How can I travel to America from Australia with my dog in the cabin or else be with him in cargo?

I want to travel to America from Australia with my dog in the cabin or else be with him in cargo.  NONE of the Airlines flying out of Australia will let me do this. I am willing to travel very rough in cargo as long as I can stay with my dog. I don't even need food, just maybe water. Flying dogs separately in cargo especially over such long distances is EXTREMELY RISKY. Many have DIED or gotten lost in transit (see , , , , ). I am a senior citizen and my dog is my only family member left alive. He means the world to me and I will not leave him behind.  Is there any solution to this? I have looked into flying privately but it is far beyond my means. Is it possible to hitch a ride on a cargo plane or military transport plane?


How to edit the transparency of the grease pencil stroke?

In my viewport, there is a stroke drawn lightly by the tablet pressure. However, the transparency of the material assigned to the stroke is 1, so it is a fairly dark color. Since the cause of this problem is the pressure applied to the stroke, not the set value of the material, I want to adjust the transparency by editing the properties of the stroke. Q: How to access the transparency properties of already drawn strokes without touching the material?


Is there anything that cancels out Small creatures' disadvantage to attack when using Heavy weapons?

A party member in a D&D 5e game I'm in is playing a halfling paladin. It occurred to me (for whatever reason) to ask what weapon they were wielding, and they said their main weapon was a maul, and their backup was a warhammer/shield combo).  Upon checking the , I discovered that  have the "Heavy" :     Heavy. Small creatures have disadvantage on attack rolls with heavy weapons. A heavy weapon’s size and bulk make it too large for a Small creature to use effectively.   The player seemed to be unaware of this (a similar character in Critical Role apparently wielded heavy weapons without issue - of course, CR is not necessarily a perfect demonstration of the rules as written).  As such, I was curious whether there is anything in the rules (i.e. not homebrew or a house rule) that cancels out this innate disadvantage for player characters, other than gaining advantage from some other source in combat.  (Note: the issue has already been resolved in our game between the player and DM, so it's purely a rules question.)


How to enable root login again after changing password?

I had enabled root login before and tried to change its password using this . But after successfully changing the password and locking it via sudo passwd -dl root. I cannot login back to SSH, it says Access is denied.  I have two users on my machine. root and admin, admin does not have su permission. When I try to use sudo on admin user, it says that admin is not in the sudoers file. That is why i need my su user back.

TikZ: How to draw a pattern at the border of a tikz path

I want to draw the shapes of airspaces according to the german VFR map style and I have problems with the restricted areas, ED-R44 in this picture:  (source: ) I already found out how to do the airspace A and B,C,D but the fill mechanism doesn't transpose to the hatch pattern I am looking for: \documentclass{minimal} \usepackage{tikz} \usetikzlibrary{patterns}  \tikzstyle{EDR}=[draw=red,line width=1pt,preaction={clip, postaction={pattern=north west lines, pattern color=red}}] \tikzstyle{D}=[draw=blue,line width=1pt,preaction={clip, postaction={draw=blue,opacity=0.5,line width=12pt}}]  \begin{document} \begin{tikzpicture} \draw[EDR] (1,0) -- (4.5,1.5) -- (4,4) -- (1,3.5) -- (2.5,2) -- cycle;  \node at (6,2) {$\rightarrow$};  \draw[EDR] (8,0) rectangle (12,4); \draw[fill=white,draw=none] (8.5,0.5) rectangle (11.5,3.5);  \draw[D] (13,0) rectangle (17,4); \end{tikzpicture} \end{document}   The problem is, that the white fill doesn't work for arbitraray polygons, but I am unable to think of a way for preaction, postaction or decoration, to make it work.


Changing boolean value inside function doesn't seem to work

I have a short question concerning changing the value of a boolean variable. bool = True  def boolean(boo):     boo = False     return boo  boolean(bool) print(bool)  What am I missing? By returning the value of 'boo' inside the function boolean should do the job, shouldn't it?` Thanks for answering.


I recently came across the approximation $$\ln n! \approx n\ln n - n + \frac{1}{6}\ln(n(1+4n(1+2n)))+\frac{1}{2}\ln \pi$$ Supposedly this was written in Ramanujan's last notebook, but I can't seem to find it anywhere else, nevermind a proof for it. Does anyone know if it was ever proven, and if so where such a proof is?


I've been given an exercise as follows:   Let $P$ be the real vector space of polynomials of degree at most $n$, and let $D$ denote the derivative, considered as a linear operator on $P$. Prove that $D$ is a nilpotent operator, meaning that $D^k = 0$ for sufficiently large $k$.  Right now, I basically have a proof that says something like "since the polynomials in $P$ have a degree of at most $n$, $n + 1$ applications of $D$ will leave any polynomial in $P$ equal to $0$". However, this doesn't sound very rigorous to me, and I feel like a proof by induction may be involved. Could somebody please give me some feedback on this? Thank you very much!   P.S. I know that this question has been answered here to some extent already, but I haven't found anything on the induction part, which is why I'm asking this question now. Thanks again!

Charging Phone with a Modified Power Supply

I have converted a computer power supply into bench top power supply and I am now ready to add some USB ports to charge various devices. On the power supply label it shows the 5v rail is capable of delivering 14 amps. If I connect a USB port to the 5v rail, will it fry my phone? (I'm assuming 14 amps will most definitely destroy my phone).   I know generally devices will only draw what current they need, but I ask because my phone obviously charges faster with a 2amp charging block vs a 1amp charging block. So therefore, if the power supply can produce 14 amps, wouldn't my phone attempt to charge at 14 amps?  Sorry in advance if this is a noob question, I have only recently started messing with electronics, or anything with electricity for that matter.


We are physicists and we are arguing over the use of "a" and "an"

Here is the situation. I am in an office full of physicists and one physicist is writing his PhD Thesis. Fundamentally, he wants to know whether he should type "an SV" or "a SV" into the computer.  SV is an acronym for "Secondary Vertex", so it is clear to us that "a secondary vertex" is correct.  So the argument is over whether   a or an "sounds better"   and additionally   is SV a new, alternative word which means the same thing as "secondary vertex" (just as one can use "roll", "bap", "barm" interchangeably in the phrase "bacon roll" to mean some bread which is probably also buttered into which one has inserted some grilled, or otherwise cooked using another method, bacon causing the butter to melt into a delicious snack most suited for eating at lunchtime. or is SV an object which is to be expanded by the readed using a previously defined definition (should one read "SV" as "secondary vertex"?)   So, he should type "a secondary vertex", but is it "an SV" or "a SV". My vote is for the former as it "sounds better". (Or at least that is my opinion.)  Finally, we also consider "an STFC" or "an SRVTLVF" to be "better sounding", however "a TRVTLVF" seems to be "better sounding". We have discovered that it doesn't seem to matter what the letters of an acronym following a first "S" letter are, the "better sounding" choice is still "an" rather than "a".  Is there a rule about whether "a" or "an" should be used for acronyms?


How does a large number of various "installed apps" affect your PC and overall PC performance?

I have recently gotten an "Adobe Creative Cloud" account. I am wanting to experiment with some of the apps, so I was thinking of downloading the entire set of apps for Creative Cloud and just start learning some, see what might, and might not benefit me as an IT guy.  I have a Windows 7 - 64 bit - Alienware MX17 that is about 2-3 years old. No issues with it ever, besides two times overheating/shutting down, where I had to send it to someone and have it cleaned, and thermal paste applied (twice in it's lifetime). Overall I get great performance, and no drag. I work and game on it "a lot".  I have 176 free out of 500, but a good bit of that are Comics.  Anyway, I installed Dreamweaver, Photoshop and a few others with no difference on performance. If I just go through and download them all, will it affect my overall performance when gaming or anything else, or does it not matter how much you have installed on it..as long as it's limited on what is running at a given time?  Thanks!


Do Bayesians believe in Fixed Effect Models?

This is the first time I'm using Ubuntu 19.10. Earlier I was a macOS user and Windows is something that everyone operates. I installed Ubuntu along side Win10 today through a USB stick and although there were some problems regarding the dpkg utility during installation, I seem to have solved it by re-configuring the package manager post install. So far the OS is running smoothly but there seem to be issues regarding the /boot directory. At every boot, I get these warnings:  # Warning 1 Could not scan some of the folders contained in "/boot" Error opening directory '/boot/lost+found': Permission denied   # Warning 2 The volume "boot" has only 9.2 mb disk space remaining.   So I have three questions:   What is the significance of lost+found directory? How do I allow access to this directory? Can I resize the /boot directory through the Disks utility?   Regarding the third question, I followed some of the advice provided at the official documentation and set the size for /boot to ~250 mb but that seems to be a bit smaller than expected. I have tried this:  sudo apt autoremove --purge  Reading package lists... Done Building dependency tree        Reading state information...

So I started a project and it mainly revolves around a manhole and a street, and it's raining, but I can't get the manhole to look wet.  One thing I tried was to mix 2 noise textures (one with a low scale and one with a high scale), and mix that with the gloss texture, however that barely changes anything.  The Road has puddles on it, ripples, etc. and practically looks pretty wet, however the manhole looks pretty dry, and I can't seem to figure out what to do to fix it.  I thought about making the ripples (made following Gleb Alexandrov's tutorial) affect the manhole too, however I don't know how to make it in a way that looks realistic, as the manhole has a displacement texture, so adding ripples on it wont really fit.  You can see the material for the manhole below, but the node system is huge, so I color-coded everything.  Dark-Blue: Texture Coordinates, Mapping, and Color Ramps  Bright Red: Mix Shader  Dark Red: Overlay Maps (although I don't think they're having much of an effect, so you can ignore them).  Green: Diffuse Stuff (The two textures are the diffuse and the AO map)  White: Reflection  Cyan (sort of): Gloss


I'm comparing two groups on the # of hospitalizations they have in a 5 year period. Length of hospitalization stay is highly variable. For example, a patient might have 3 hospitalizations that in total lasted 100 days, where as another patient might have had 50 visits, each lasting a single day. Therefore, It would seem natural to factor in length of stay (in days) into the picture.  Right now I'm thinking of a Poisson Rate Regression, with a single categorical predictor (Group) and # of hospitalizations as the DV. I'd like to include Total Length of hospitalization stays as an offset, which is in days. My question is, I have some patients who did not have any hospitalizations, therefore their length of stay is effectively 0.   In order to hit the Poisson Rate Regression model (in SAS anyway), I must log the offset term. I clearly can't take the log of 0, so I'm wondering what can I do in this situation? Can we add a constant of 1 to both Hospitalization and Total Length of Hospitalization to remedy this?  (cross posted @ Talkstats.com)

I need to search for the first occurrence of text between single quotes, return the text (without the quotes), but if there is no quoted text is found, return null. I cannot use any additional methods.  For example:   On input "this is some 'text' and some 'additional text'" the method should return: text On input "this is an empty string '' and another 'string'" it should return: nothing.   My code:       public static String findSingleQuotedTextSimple(String input) {         Pattern pattern = Pattern.compile ("(?:^|\\s)'([^']*?)'(?:$|\\s)");         Matcher matcher = pattern.matcher (input);         if (matcher.find()) {             return (matcher.group ());         }         else {             return null;         }     }   However I seem to fail the test and the output is null every time, please help me point out the problem.

How do you correctly use a meat thermometer?

I have two meat thermometers. I bought a second one because I thought the first one was resulting in overcooked meat, however the new one is doing the same! They are both standard metal prong 'analog style' with a needle.  An example - cooking chicken breast. The thermometer says the temperature must reach 77 degrees Celsius. I cooked it for a short time in a griddle pan first and then put the pan in the oven. The temperature hung around 71 degrees and when it didn't seem to be getting any higher and I felt it was overcooking I pulled it out. Sure enough, overcooked!  How can I use a meat thermometer to cook meat correctly?

Font Setup for an Academic Thesis, no Computer Modern Wanted

I want to help a friend to set up a template for his thesis.  So far I used the lmodern package for almost everything. But I think that the readability of computer modern on a screen is not really good (printed it is good). In addition lmodern or cm look very common because almost everyone uses it.  What font setup (math/text) would you recommend to spice a document up a little (it is still a academic thesis). It will be written in German and will contain a fair amount of math and listings too. It should look good on a screen too.  I once read that Lucida Bright is a great font regarding my demands. But it is not free. I also read that the The LaTeX Companion is written with Lucida Bright.  It is important that the math font contains upright and italic greek letters.  Listing to start:  \documentclass[]{article}  \usepackage[latin1]{inputenc} \usepackage[T1]{fontenc} \usepackage{lmodern} \usepackage[english]{babel}  \usepackage{blindtext}  \begin{document}  \section{Test Title} \blindtext  \begin{description} \item[serif] Test Test \item[sans serif] \textsf{Test Test} \item[typewriter] \texttt{Test Test} \item[math] $a^2+b^2= c^2$ \end{description}  \end{document}   Output with \usepackage{lmodern}    Output with \usepackage[sc]{mathpazo}

Best Practices in Username Standards: Avoiding Problems

I'm interested in finding out what people's experiences with standard usernames is. I've always been in places that used {firstInitial}{lastname} (sometimes with a length-limit). Now I've users that want {firstname}.{lastname} - and now it comes up that the period may cause problems.  Specifically:   What is the best username length limit to use to maintain compatibility across all uses? What characters should be avoided?   UPDATE: The reason I didn't mention specifics is that I wanted to be general enough to handle anything that might come up in the future. However, that may be too general of a requirement (anything can happen, right?).  This is our environment: Ubuntu Server Lucid Lynx 10.04 LTS, Red Hat Enterprise Linux 5.6 and up, Windows Server 2003 and Windows 2000 Server (with Active Directory in Windows 2000 Native Mode), Zimbra 7.x for mail, and OpenLDAP in the near future.  UPDATE: I should mention (for completeness) that I saw  (though it didn't answer my asked question) and also this , both of which were very informative.

I can select all "w" nodes with XmlNodeList w = xdoc.GetElementsByTagName("w");  I found that XPath can be really helpful here, but I can't get that to work. I tried root.SelectNodes("//w[address != \"asd\"]");, but this isn't returning anything. I thought maybe the namespace is the problem here, so I tried root.SelectNodes("//namespace:w");, but that throws an exception:  System.Xml.XPath.XPathException: 'Namespace Manager or XsltContext needed. This query has a prefix, variable, or user-defined function.'  If I remove the root node's arguments, and "xsi:" in front of the types, it works. How can I get it to work when there is a namespace? Can someone help me please how can I do this? Thanks!


What is the intuition behind the notion of strong differentiation?

${\bf definition.}$ A function $f$ defined on open set $A \subseteq  \mathbb{R}$ is said to be ${\bf strong \; differentiable}$ at $a \in  A$ if       $$ \lim_{(x_1,x_2)  \to (a,a) \\  x_1 \neq x_2 } \dfrac{ f(x_1)-f(x_2)  }{x_1-x_2} = f^{*}(a)$$      exists and is finite and we call $f^*(a)$ the strong derivative of $f$   at $x=a$   How is this notion different than the usual derivative?  I mean, if we set $x_2 = a$, we get our usual derivative...  What is the point of such definition? what is motivation for this?


Do Cantrips stack when you multiclass Spellcasting class of the same casting type (Wizard, Edlrich Knight, Arcane Trickster)? Ex: Lv 10 Arcane Trickster has 4 cantrips & Lv 10 Wizard has 5. Does the mean this PC knows 9 cantrips?    Sadly this did not help as they used two different spellcasting type.

How to add a month to an Excel date value?

I tried to google for a while but it seems to have no straight forward way to do this math.   For example, we have the date at B2 12/31/2012 and need to add 2 months to it and store value in B4. What is the direct formula to use? I rather not using any 3rd party addon(s).


So I have a second hand notebook. The previous owner seems solid and says that for him, he was able to catch his Wifi router without any issues, even when he was in front of his house and the router was in 3rd floor inside...  Now I am the owner and the laptop was in service once. I used wired lan before so I did not care, but now I tried the wifi adapter and it is almost useless. I have wifi router RIGHT next to it and it indicates only 3 bars out of 5. Any other wifi routers in the house are inaccessible.  I was looking into the computer and wifi antenna is connected. I even tried to switch the main and aux antennas and it did not help at all. When I disconnect antennas and just leave the adapter without them, I get 2 bars out of 5 in the same experiment as before.  I even took the whole computer apart (inc. display) and the antennas do not appear to be damaged or severed anywhere... This is a little mystery to me. What else can I try?


How to teleport a player upwards every two seconds?

I want to make a setup with command blocks that will, if you hold a specific item, elevate you 100 blocks. For example, when you hold an ender pearl named "Sky Orb", you would be teleported 100 blocks up each couple of seconds. I already have the necessary commands:  /scoreboard objectives add Holding dummy /scoreboard players set @a Holding 0 /scoreboard players set @a Holding 1 {SelectedItem:{id:"minecraft:ender_pearl",tag:{display:{Name:"Sky Orb"}}}} /tp @a[score_Holding_min=1] ~ ~100 ~    Basically, the main problem is the delay. You should only be teleported every 2 seconds or so. Does anyone know a setup for this?  (I'm using the 1.9 snapshots)


Is there something wrong with "Mmmm Bacon" hat mechanism?

Today while searching I voted on a question and suddenly got a hat so out of curiosity I checked it and it said I received a "Mmmm Bacon" hat, as shown below.     Now the question is how a hat that is to be awarded on 30th of December is awarded on 29th of December? Is this a bug or something else that I failed to understand?


Notification "Congrats, you've gained the privilege – participate in meta" for the reputation gain in Meta

I am a meta user already and gained some initial reputation. On that, I got a notification like the one shown below in the image:  "Congrats, you've gained the privilege – participate in meta"    This is a probable bug since I am already a Meta user and this notification stands irrelevant now.


Find the radius and interval of convergence of the series $\sum\limits _{n=0}^{\infty} n!x^n$

I used ratio test and ended up with $|x|\lim \limits _{n\rightarrow \infty}(n+1)$  If $x\neq 0$, the limit is infinite and thus the series diverges. Now, when $x=0$, I have the series $\sum\limits _{n=0}^{\infty} n!0^n$  I am sure that all terms will be zero except the first term with $0^0$. I know this to be one of the indeterminate forms and I am not sure of what to do with it.


ffmpeg working from command line in Terminal but not in an Automator shell script!

I have just compiled my own copy of ffmpeg on my system and it's located in the following path:  /opt/local/bin/ffmpeg   When I run the following command in Terminal.app, it runs smooth:  ffmpeg -i /Users/Amit/Documents/input.avi -c:v copy -c:a aac -b:a 384k -strict -2 /Users/Amit/Documents/output.m4v   However, a similar command run as a shell-script in an Automator service fails:  for f in "$@" do     ffmpeg -i "$f" -c:v copy -c:a aac -b:a 384k -strict -2 "${f%.*}.m4v" done   Up until now, I had a pre-compiled build of ffmpeg on my system located at:  /Applications/Scriptlets/   And my Automator shell-script had the full path (/Applications/Scriptlets/ffmpeg) instead of just ffmpeg; and it worked fine. However, today I decided to compile a fresh copy of ffmpeg using MacPorts and removed the earlier version from my Applications/Scriptlets folder. Now, this ffmpeg works fine in Terminal but gives an error whenever I try running it from a shell-script inside of an Automator workflow. Am I doing something wrong here? Please help!


At the time of Harry Potter and the Chamber of Secrets we have 2 conscious and functioning Horcruxes - young Tom Riddle from the Diary and the "main piece" hiding somewhere in Albania.   Young Tom Riddle reveals that he is not aware of the future - it's Ginny who told him that Voldemort was defeated when trying to kill Harry.     “Well, you see, Ginny told me all about you, Harry,” said Riddle. “Your whole fascinating history.“ His eyes roved over the lightning scar on Harry’s forehead, and their expression grew hungrier. “I knew I must find out more about you, talk to you, meet you if I could. So I decided to show you my famous capture of that great oaf, Hagrid, to gain your trust—”      [...]      “Haven’t I already told you,” said Riddle quietly, “that killing Mudbloods doesn’t matter to me anymore? For many months now, my new target has been—you.”      [...]      “So I made Ginny write her own farewell on the wall and come down here to wait. She struggled and cried and became very boring. But there isn’t much life left in her… She put too much into the diary, into me. Enough to let me leave its pages at last… I have been waiting for you to appear since we arrived here. I knew you’d come. I have many questions for you, Harry Potter.”      “Like what?” Harry spat, fists still clenched.      “Well,” said Riddle, smiling pleasantly, “how is it that you a skinny boy with no extraordinary magical talent—managed to defeat the greatest wizard of all time? How did you escape with nothing but a scar, while Lord Voldemort’s powers were destroyed?” There was an odd red gleam in his hungry eyes now.      — Harry Potter and the Chamber of Secrets, chapter 17, The Heir of Slytherin   It is quite clear, that the Diary only has a memory of 16 years old Tom Riddle.  If he were to win that fight and consume Ginny, what would happen with his memory? What would be his memory state at the moment?   addresses whether there would be 2 Voldemorts and how would they interact. For the sake of this question, I set that aside and actually ask in what state exactly will Voldemort's memory be and why. I see three possible outcomes:   The memory of Tom Riddle from the diary will merge with the original Voldemort's memory (though I'm not sure in this one since Voldemort doesn't seem to have any connection to his Horcruxes as he doesn't even notice them being destroyed) Riddle's 16 y.o. identity will dominate and be more or less single source of memory since that is Horcrux's condition vice versa original Voldemort's identity will prevail since he's the original one and have higher ground on this. He can't die while there's at least a single Horcrux, while Horcruxes can be destroyed, which places his original part higher.


Escaping characters in command line search and replace

In Unix (running MacOS High Sierra), I've seen a few different search/replace (over several files) methods, e.g.:  perl -pi -w -e 's/SEARCH_FOR/REPLACE_WITH/g;' *.txt   or using sed or grep, etc. The problem is, how do I escape my search strings properly?  For example, if I need to replace http://my.site/dir with http://new.my.site/dir, obviously I can't include forward slashes in my search string without escaping.


Is there a word for a question asked despite knowing the answer, but meant to elicit a response for the sake of the audience?

In journalistic writing I often see writers, correspondents, and interviewers use questions in non-literal ways.  Of course there are rhetorical questions designed to make a point and not meant to literally elicit an answer.   Instead of that, I have in mind when an interviewer asks a correspondent, "why did she not go to the police?" when the interviewer already knows the story and knows the answer to the question, but wants the correspondent to articulate the answer for the audience's benefit.    Is there a commonly used term for this sort of a question?  A "leading" question generally implies an attempt to manipulate the respondent into giving certain responses, which is not exactly the same as what I'm describing.


Unable to access “319 GB Volume”. Windows didn't shut down properly

I am absolutely brand new to Ubuntu, having tried it a few years ago and didn't continue with it because my often used software would not work on it.  I still need to use Windows from time to time and I have a dual boot system on a Dell Inspiron n5010 laptop.  This morning when using Windows, Skype tried and failed to update.  I shut down restarted and booted to Ubuntu.  Trying to access the files in the windows partition gave this message:  Error mounting /dev/sda3 at /media/nick/426268B36268AD7B: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000" "/dev/sda3" "/media/nick/426268B36268AD7B"' exited with non-zero exit status 14: Windows is hibernated, refused to mount. Failed to mount '/dev/sda3': Operation not permitted The NTFS partition is in an unsafe state. Please resume and shutdown Windows fully (no hibernation or fast restarting), or mount the volume read-only with the 'ro' mount option.   I shutdown Widows fully but still get the same error.  At this stage I don't know enough to or mount the volume read-only with the 'ro' mount option.  Since posting this question I have found that restarting rather than shutting down after using windows cured the problem.  I have no hibernate option in my windows 10


I'm working on a site which had default link structure like domain/post-slug. The content team wanted me change it to domain/blog/post-slug so I added /blog/ in custom structure field in permalinks settings. The problem is that it added /blog/ to other custom post types as well for example domain/blog/case-studies/post-slug (case study is a custom post type we have). Now they want me to remove /blog/ from custom post types and only keep it for blog articles. There are other instances where they want me to add a certain words like services in the link structure of some pages. I've tried some plugins but so far none seem to fit this use case. How do I achieve this? I'm using wordpress 5.7


Postfix forwards to Gmail being rate limited even with unmodified headers

I've installed Postfix on Ubuntu 14.04 with the defaults. I then configured some virtual aliases to forward email from a few addresses to various personal (mostly Gmail) accounts. This is just to make these addresses all connect cosmetically to the domain on the website we are hosting.   Unfortunately, in a short amount of time Gmail has started rate blocking the forwarded emails due to spam. Apparently, Postfix is rewriting the headers in a way that makes Gmail think all the spam is originating with our server. Google  for information on how to best forward to them.  In it, they say:     We recommend that you do not change the envelope sender when   forwarding email to Gmail. Sometimes, when forwarding email, the   envelope sender gets changed to your domain. When this happens, Gmail   may learn that your domain is sending spam, and will treat other   emails from this domain as spam as well.   This make sense, but it would still seem that Gmail would have to see the IP and hostname of our mail server and register it as a source of spam. But this is what they say and I've found nothing on point anywhere.   I even tried using Mailgun to filter the forwards as they provide spam blocking, but within a day they deactivated the domain and are being rather slow to respond to my inquiries. Any help is appreciated. I would like to avoid a full fledged mail server setup just to handle a few rarely used forwards.  Update: My original assumption was incorrect in that Postfix is not rewriting the headers, however the original issue remains. Gmail is rate limiting forwards due to excessive spam. It would be understandable if they limited the servers that are actually sending the email, and these are listed in the headers as part of the delivery chain.


I have this table:  ------------------ | id   | foods   | ------------------ | 1    | cookies | | 2    | cake    | | 3    | milk    | ------------------   And this table:  ------------------ | id   | colors  | ------------------ | 1    | red     | | 1    | blue    | | 1    | pink    | | 2    | orange  | | 2    | yellow  | | 2    | purple  | | 3    | cyan    | | 3    | gold    | | 3    | silver  | ------------------   I want to SELECT the foods from the first table and match them with the colors from the second table, based on id.  So I want the output to look like this:  -------------------------------------------- | id   | foods   | colors                  | -------------------------------------------- | 1    | cookies | red, blue, pink         | | 2    | cake    | orange, yellow, purple  | | 3    | milk    | cyan, gold, silver      | --------------------------------------------   How can I do this?  EDIT: This is not a duplicate. I am not trying to concatenate. I am trying to merge a concatenated table into a regular table based on ID.


In Star Trek, why do Federation / Starfleet ships always seem to delay returning fire until it's almost too late?

I keep seeing this situation in Star Trek series:     "Captain, they've raised shields!"   "Now they're charging their weapons!"   "Captain, they're targeting our engines!"   "OK Ensign, evasive maneuvers."   BOOM   "Shields are holding, Captain, we're at 25%."   "They're coming about for another pass!"   BOOM   "Captain that one took out our warp drive, shields are offline as are phasers"   "Ensign, target their weapons array with a photon torpedo."   "Captain, they're hailing us..."   "Ok, belay that, put 'em on-screen."     & from this point they're possibly boarded, taken hostage, all kinds of bad outcomes that they have to come back from. One might imagine that a well-equipped cruiser would drill for such eventualities. I'd imagine it more like:     "Captain, they're raising shields!"   "Folks, you know what to do - defend the ship!"   All over the ship the crew work together as a well-oiled machine. Shields go up,    phasers take out the bad guys' weapons & engines faster than the other guys can    react, while simultaneously the helmsman takes them through a series of seemingly    random maneuvers designed to make them a very slippery target.   "OK hail them, see why they made an aggressive move on us."     Any reason why it's always the former & never the latter case?


How do I prove that $3$ divides $14^{2n}-1$ by induction?

How do I solve this?  Prove that $3$ divides $14^{2n} -1$ for all $n = 0,\,1,\,2,\,3,\,\ldots$  My calculations are:     Let $n=1$ then $3|14^{2*1}-1 \implies 3|196-1 \implies 3|195$ which is true      Now $n = k$ and assume $3|14^{2k}-1$      let $n = k + 1$      $3|14^{2(k+1)}-1 \implies 3|14^2*14^{k+1}-1$      and $3|14^2-1$ so $3|14^2*14^{k+1}-1$      which makes $3 | 14^{2n}$ true.   I tried starting with $n = 0$ as it's the smallest base but I couldn't get it to work.


What's the best way to find outliers in the time-series, encountering that it is a real-world mechanical process (process continuity)?

What's the best way to find outliers in the time-series, encountering continuity? I attached two time-series that I'm interested to filter. One is less noisy, and one is a bit noisier. I'm mostly interested in the first one. BTW the data looks like it is periodic, however, it is not and it is quite short (200-500 samples). Also, I don't know much about the process Thanks


In a simple float operation, is there any difference between multiplication and division?

I was wondering if there could be a a little difference (for performance issues) between multiplication and division in a simple compute like in:   float thing = Mouse.getDY() * 0.1f; float otherThing = Mouse.getDY() / 10f;   when this kind of things happens a lot, of course, for example in camera position calculation in a 3D game (lwjgl).  Thanks !

Latex longtable, start equation on new line

I'm trying to get an equation go to a new line in a table, in latex.  Basically I want it look something like this:    column 1         column 2               column 3 (equation)          (text)               (equation)    A+B+C           quite long text         A+B+C,  A=B+C,                   that gets split up              B=D-G                   as you write    B+G+H+J         more long text that    A+Y+J+K, A=F+G+L                   that wraps around               F=B-R+H+L  [other equation]   [more long text]      A+F+H [<- only this equation]   The specific format I'm looking to make is that of the one in column 3, where the 3rd equation is directly under the 2nd equation.   However only in certain rows like row 1 and 2. Row 3 just has a single equation, that doesn't need to take that format.   I'm doing this because certain lines are too long and go off the end of the page. And I to want to split it up, column 1 is just 1 long equation which I can't split up. Column 2 is just text, and I've found a way to wrap it around quiet nicely. Column 3 however consists of either 1, 2, or 3 different equations, and I want to bring an equation down to the next line, but in the format I need, equation 3 below 2.   I've tried using the format of column 2, in column 3, messes up all my equations in the other rows of the table.  Any help would be appreciated, my code and a picture of how my current pdf looks, is below:   \documentclass[10pt,a4paper]{article} \setlength{\abovecaptionskip}{5mm} \usepackage{array} \newcolumntype{L}{>{\centering}m{5cm}} \newcolumntype{j}m{5cm}} \setlength{\extrarowheight}{2.5mm} \usepackage{amsmath} \usepackage{multicol} \usepackage{float} \usepackage{longtable}  ~ all preamble ~  \begin{Document}  ...  ...  \renewcommand{\arraystretch}{1.7}  \begin{longtable}{ l L l }  $\overline{X} \cdotp Y \cdotp Z + \overline{X \cdotp \overline{Y} \cdotp  \overline{Z} + X \cdotp Y \cdotp Z} $ &   Use De Morgan's law [OR to AND] &   $ \overline{A+B} = \overline{A} \cdotp \overline{B}, $  $ \quad A = X \cdotp \overline{Y} \cdotp \overline{Z}, $ $\quad B = X \cdotp Y \cdotp Z $ \\\  ...  more similiar rows  ...  \end{longtable}  \end{document}


I have a problem identifying what fonts are used in typesetting these pdf documents. However, since I'm a beginner here with low reputation, I can't post an image caption of the files. Even if I could do so, the quality of the image is so low that I'm afraid won't be clear enough in order to identify the fonts correctly. So I managed to upload two examples pdf files in Dropbox and put the links here. I'm sorry if that may cause you any difficulty.  For the first font, the letters look almost the same as the default font of Latex typesetting. However there's a small difference. You can view it in the sample file . For the second, the letters are slightly fatter. You can view it .  Any help is greatly appreciated. I really don't know who to ask, because I just encountered the pdf files, not the .tex files, and had no idea what fonts are used.


Short story, where FTL travel is very simple but humans never discovered it

I read a short story (I think, but it might have been a novel), where most races discover a very easy way to travel faster than light at a certain point in their technological development.   What I remember:   The guys in wooden ships bounced around subjugating the people without FTL travel. Earth had never figured out the FTL, and so had poured its effort in a different path, achieving present day technology. The aliens were freaking out about handing the humans FTL travel. The story was told from the point of view of the aliens. I read it in the last 10 years, but there is no telling how old it actually was, although I do remember them mentioning F-18s or F-14s.


Are there any works, canon or otherwise, that deal with the concept of the Founders, or other shapeshifters, being assimilated or otherwise encountering the Borg?  The idea of an assimilated Founder just came to me, and the difficulty of inserting nanoprobes into a non-solid mass interests me. I suspect the answer to this question is negative, but am curious.


I've been a designer for 6 months, having previously had a 1st class honours degree in Graphic Communication. My issue is that I am a Very good designer, but I work too slow. It's beginning to drive a rift between myself and the creative director who desperately wants me to work quicker. I've always been a workaholic even in university, I put in 110% all the time, really work my ass off, but I'm still not fast enough to complete projects quickly, my work is good, but it's not efficient.  Do you guys have any tips to help me speed up?

Creating Thiessen Polygons (Analysis) by defining external feature boundary?

Although this issue has been addressed in this post some months ago: , the appropriate answer has not been given. So, new ideas are welcome.   How can we use the Create Thiessen Polygons (Analysis) tool available with ArcInfo license by defining an external feature boundary (e.g. study area boundaries defined by a polygon) for the created thiessen polygons?  As I have seen this is not possible via the Environments...options in that tool.   Is there any available code in VBA for doing this? or How can I run this tool within a VBA code?  The comments indicate that ArcGIS 9.2 and 9.3 is being used, the tag indicates version 10, the first post is for that version not previous ones.


What can LVM do that standard partition can't?

I haven't spent much time dealing with standard partition. Aside from "LVM makes it easier" to manage disk, what really can LVM do that standard partition can't?  All I can think of right now is that your LV(Logical Volume) can be a combination of multiple hard disks. Can you also add size to your volume by shrinking another volume in standard partition?


Scalar product on Lie algebra of compact Lie group

I am studying Differential Geometry and I am facing with a lemma in which there is a step that I do not understand. In particular, let $G$ be a connected compact Lie group, is used "$\langle\ \cdot , \cdot \rangle$ any $Ad(G)$-invariant scalar product (or equivalently a non-degenerate semi-positive bilinear form) on $\mathfrak{g}$, the Lie algebra of $G$ ". I can't find any such of scalar product.  When a connected compact Lie group $G$ has such a scalar product? I tried with the Killing form that is semi-definite negative bilinear form, that is non-degenerate iff the lie algebra is semisimple, but how I can prove that a compact connected Lie group have semisimple Lie algebra?  I tried also with a proposition (3.6.2) in "lie groups", Duistermaat-Kolk, saying that the killing form of a lie algebra $\mathfrak{g}$ is negative on the complement of the center $\mathfrak{z}$ of $\mathfrak{g}$. Then if I prove that $G$ is centerless, so is $\mathfrak{g}$ and the opposite of the killing form is an $Ad(G)$-invariant scalar product on $\mathfrak{g}$.  $\underline{NOTE}$: The lemma I have to do states "Two maximal tori of a compact connected Lie group $G$ are coniugate", so we can suppose that $G$ is non-abelian.

Can I configure my Mac to store documents and pictures on iCloud only

I am using the latest macOS Mojave, and I have a Mac which only has 250 GB of storage space. Due to the nature of my work, I need as much of this space available at all times.  I will sporadically need 100+ GB for a short duration of time for example. The problem with iCloud is that it optimises so to store as much as possible on the Mac at anytime and this causes me problems. Yes it will delete some local content when I am short on space but it takes too long.  I want iCloud switched on and accessible from my Mac, I just want it to keep everything on iCloud. Why does this not seem to be a feature or am I missing something?  It seems to leave me with 25 GB, which is 10% available so maybe this is a setting?

What is the danger of running untrusted software as a normal user

Sometimes I have to use some propriety softwares which I don't trust or even pre-compiled open source ones which I don't know if they've been compiled as their source are.   Lets say we installed a propriety application in /opt/software, then we run it as a normal user (without sudo, gksudo, etc).   I know when we run a program it is able to connect to the Internet, monitor X, keystrokes, collect user data and so on. It can't change anything important in the system or infect the system, (because of the Linux permissions system). It is possible for program to add some plug-in/extension to a user's browser (Because browser profiles are available in user home directory). After closing the program and rebooting it can't do anything anymore. Wrong because:   Program can add itself to a shell/file/directory which does the autostart process, so it will run at any login.  If we consider the autostart process clean, without rebooting there is a chance that a process of the program is still active. Programs can delete or modify any file in the user home directory (or any other file which a user has write permission to).   So what should we do?   I think the only safe way to run a propriety program is running it as another user. If running the program as another user somehow is not possible then we should change the autostart files permission so only root can change them. then after closing the program a reboot will do the job.   Am I right? Is there anything that I'm missing?

Image Texture is duplicating itself across the back of the image?

I am trying to create an eye. Sounds simple, and it should be simple but I'm having a frustrating problem.   For some reason, when I apply a texture, the UV mapping sends the texture to the back of the eyeball and the mesh itself has a square pupil rather than a circular one.   If I flip normals, nothing happens. If I scale the UV mapping by hitting "S 1", it sends the texture to the front which is great, but duplicates the eye texture like a hundred times along the sides and back of the eyeball.      These are the only nodes I am using so far on the material.  I've tried looking into this for hours with no success. Does anyone know why this would be happening? I don't think it's the the picture I'm using either, I've tried other 3D eye pics and they all have the same issue.  The UV mapping is also huge compared the the original graph, since scaling is the only way I've been able to send the texture to the front of the eye.  I am fairly new to Blender and I appreciate any guidance that'll help me continue growing.


Can't boot to Windows 8 after installing Ubuntu

First of all, I know a lot of people has asked this question, but after revising a lot of questions, I didn't find my answer so I ask here because I'm desesperated and I need a solution... Here's my problem:    I have Windows 8.1 preinstalled in my PC, and I've also installed Ubuntu 12.04. Firstly, when I installed it, it worked perfectly and I didn't have any problem running the two OS. But, lately, this last week, it gave me some errors because I couldn't start Ubuntu, so I reinstalled it. The problem now is that when I try to access my Windows 8.1, it gives me this error:     Error: no boot disk has been detected or the disk has failed.   When I enter my BIOS settings, it successfully shows the Windows Boot Manager under the boot menu options, but when I try to access it, it gives me that error. Also, I've tried to solve the problem with the Windows 8 recovery mode but it doesn't detect my OS... I know my hard drive is working, because I can access to my Ubuntu and I can also access my Windows 8 files through Ubuntu.  I've found  but I'm not sure if it's what I have to do, is it? If this could solve my problem, I'm stucked in the first step where I have to assign my EFI partition a drive letter, because I don't know which volume is my EFI partition.   So, I would appreciate it a lot if you could help me because I really need to access my Windows 8.1 without losing any data... Thanks!

How to authenticate to sql server as Windows User from java application?

I have a puzzle i must solve.  On a client server application written  in  Delphi + SQL Server the app users are mapped to SQL Server users. In this way the user logs in from the client using SQL Server credentials and it is authenticated and logged. Then the app uses sa to run all queries, the system is designed in a way that the user who logs in to the database can just query a table where the encrypted sa password is visible, so the app reads the password, decrypts it and logs in as sa.  The users can  be either with sql server authentication than Windows authentication.  In the DB there is a  USERS  table in  which username are stored, those match with SQL Server Login names, in case of Windows Authentication the uesrname is stored as "DOMAIN\User", in case of sql authenication simpy as "User".  i am writing a java web application that must keep the same authentication system for the users: the app connects to th db with JDBC using the sa user, but in the login form the user must input its sql server login  data. Since the webapp must be used also outside of the LAN/VPN i'd like that also the Windows auth users can pass login by typing DOMAIN\User in the name field and the password in the password field.  For SQL auth users it is simple, i just try to exectute a query the password table (the only one visible) in a try catch block, while connceted as the User who tries to login, in case of non  raised exception i consider the login succesful. It works.  The problem  comes with WIndows auth users. After a lot of research i  foudn out that a solution could be to try to connect to the LDAP server just to check if the provided DOMAIN\User and password are correct. I am currently exploring this idea, i asked  for this reason.  The question i am asking here is about t he whole process. Is this aprpoach correct or should i consider alternative ideas like create a "WebPassword" field to be used by Win auth users when loggin in  to the webapp?  In another webapp I made with  (VCL for the web) i was able to perform my task since the DAC component i used () allows to connect to sql server by passing at runtime DOMAIN\USER and password of any other user. This is not possible in jdbc so i already discarded this idea.  Please keep in mind that this question is about "migrating an old client server application to the web by keeping old authentication system (because client server and web must coexist)".

how do I restore to a previous version wherein the .env file is available

Just a dumb question from just a newb in git, Messed up alot with git, but now I was wondering if how can I restore to a previous version in the application, since my .env environment configuration file is now gone in my current master branch, I did merge my other branch with this one. I knew I made my latest work on my chat-feature branch, pretty much the 100% of the application was there, since the chat part and the payment feature of the application was there but when I checkout there, its not even working, I was wondering how can I go back to that previous commit that I made. When I git log I want to be back to this specific version.


Why do I still read voltage on outlet when I turn off breaker?

I have an GFCI outlet box wired with yellow coated wire, which I believe goes to a dedicated circuit breaker. When I turn off the breaker to the box, I still read residual voltage.  Is this induced "phantom voltage"? Is it safe?  This outlet box is underneath a jetted tub, so I want to be sure there is no voltage in the box when I turn of the circuit breaker.   The 3 tools I used to measure the voltage are:  1) Gardner Bender GDT-3190 multimeter (10 MOhm input impedance) - when pluged in to outlet hot and neutral, multimeter reads 2.1V on 200V AC setting.   2) Klein Tools NCVT-2 proximity Voltage Tester - when close to the yellow wire, tester beeps for voltage reading on 12-48V scale, but not for 48 - 1000V scale.   3) SPERRY GFI6302 outlet tester - reads open hot, so not picking up any voltage.   Thanks for the help!


Sci-fi series from 2000s with alien-like characters and a character resembling fire

As a child I watched a couple of episodes of a sci-fi series set on a planet, that was far from resembling Earth - I remember a dark, stoney scenery and tanks of some form. It was probably in English, and it was a 3D animated series.  The only thing I really remember is a character that was burning, it was basically a walking fire with black eyes and flames instead of hair, the entire being just burned and it was orange/yellow- a fire. And then there were some sort of aliens or alien-like creatures, a father and a son, or a father and a daughter. in some way they resembeled bugs. The ''fireman'', and those two aliens were the ''good guys'' of the series, but I can't remember what they fought against or ran away of...


Why does SO allow people to continue answering a question when one is accepted and highly voted up?

Simple question, title says it all. For example I have a few posts where the answers that are accepted are highly voted up by the community, which indicates they are, based on my questions, vastly right. Now I am not your copy, paste programmer who lives on SO, but I do use SO for understanding issues and problems and seeing new ideas and solutions to existing issues that I cannot figure out. Lets take an example post, call it "How to do x in x language" The question might have an answer with a vote of 100+, while other answers that still come in years later get instantly downvoted. Why does stack allow people to continue answering after a question has accepted what they deem to be the right answer based off the info provided, the votes and maybe the example solution (keyword: example). Why? I could see if there was no accepted answer, or every answer was below a certain threshhold in terms of voting. But questions after 6 months, regardless of accepted answer or not, should be closed - like GitHub. Thoughts?

How to prove that : $\sum \limits_{k=0}^{n-1} \lfloor x+\frac{k}{n}\rfloor = \lfloor nx\rfloor$?

for all $x\in \mathbb{R}$ and $n\in\mathbb{N}^*$ without using euclidian division.  First I re-write the sum in this way : $\sum \limits_{k=0}^{n-1} \lfloor x+\frac{k}{n}\rfloor = \lfloor x\rfloor+\lfloor x+\frac{1}{n}\rfloor+... +\lfloor x+\frac{i-1}{n}\rfloor+ \lfloor x+1-\frac{i}{n}\rfloor+...+\lfloor x+1-\frac{1}{n}\rfloor$   Now we can see that there is two possibilities for $x$ between two natural numbers $[q,q+1]$. Indeed we have the part $\sum \limits_{k=0}^{i-1}\lfloor x+\frac{k}{n}\rfloor=ji$ with $0\le j\le n$.And the other part $\sum \limits_{k=i}^{n-1}\lfloor x+1-\frac{k}{n}\rfloor=(j+1)(n-i)$.  Finally the floor will be $nj+(n-i)$.  Now for $\lfloor nx \rfloor$ it will be between $[nq,nq+q]$ which lets $n$ possibilities for its values but it would be perfect if it was $nj+(n-i)$ .  Thanks in advance !

Are people really going to use public IPv6 addresses on their private networks?

I have been reading the , and I came across this passage in the gateway section:     ...Note that NAT is only relevant for IPv4 and its limited address space;   in IPv6, the wide availability of addresses greatly reduces the   usefulness of NAT by allowing all “internal” addresses to be directly   routable on the Internet (this does not imply that internal machines   are accessible, since intermediary firewalls can filter traffic).   That got me thinking... With IPv6 there is still a private range.  See: .  Are companies really going to set up all their internal machines with public addresses?  Is that how IPv6 is intended to work?

The title is basically my question.  I've use TEdit to remove all of the stone and dirt Crimson in my world, but the background walls don't seem to be removed by TEdit.  Will these wall blocks make the Crimson spread in my world still, or am I safe?


Is exporting to feature class the simplest way to make joins permanent?

I am a new user doing simple tasks with ArcMap 10.1  I have a shapefile and an excel file, and I want the join to be a permanent part of the shapefile. The way I've been going about this is to export the shapefile into a feature class within a database. Is this the most efficient way to go about saving the joined attributes?


Why does my Xbox keep signing me out of Xbox live

When ever I am playing Xbox it randomly signs me into Xbox live then later will sign me out of Xbox live and I don't know how to fix this little issue. If anyone knows the answer it would be much appreciated if you could help me out.

Newbie Question: in Blender 2.8 Adding Armature options missing?

I did try searching for this but didn't find anything.   I've been following some tutorials for Rigging and have seen a lot of videos showing  Armature Templates available from the Armature sub option see attached.  On the version of blender I'm using 2.8 Beta Win 10 64 bit (23 April 19) I have no options to select anything.  Only the Armature menu heading is from the ADD option  which when selected provides a single bone.  Have these other options gone now or do I need to configure something within blender?  Thanks


Adverb position in "Listen carefully to what I say"

I've come across the phrase "Listen carefully to what I say" and I'm really not sure why carefully has gone in between listen and to. It doesn't happen with other verbs; you don't "switch carefully on the light", for example.  When can an adverb follow a verb, and when can it not?


Windows 7 – Red Cross on Network Icon After Incoming VPN

After creating a New Incoming VPN Connection in my Windows 7 Ultimate 32 SP1, the Network Icon in the System Tray always shows a red cross mark even though I am perfectly connected to the LAN & Internet.  This issue is already discussed  on Super User.  However, the solutions posted there did not work in my case.    What all I have tried so far, including earlier suggested solutions to the old question:   Deleted the subkey 'Config' from HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network and restarted Windows. Waited for over 10 minutes but the red cross mark remains. Release, Renew, FlushDNS IP address. Full uninstall & reinstall of latest drives of Realtek PCIe GBE Network adapter. (Gigabyte 880GM USB3 Rev 3.1 board) Disable & Re-Enable Network Adapter. Updated Windows 7 SP1 with Convenience roll-up update.   Even after incoming VPN connection is established, it continues to show the cross mark.   If I start in Safe Mode with Networking then only it’s gone but only during Safe Mode.  Does anyone know if this is a bug in Windows 7 and is there any particular update that fixes it?


How do I typeset arbitrary fractions like the standard symbol for .5 = ½?

I know I've seen somewhere how to typeset 1/2 as ½, but with arbitrary fractions (that is, a macro that takes two arguments and makes the first denominator and the second numerator...). Now I can't seem to find it.  How do I typeset an arbitrary fraction the same way as ½?


maximum via current carrying capacity pcb

As I know, there exist limits on maximum current, a pcb via can tolerate before it melts before the via's temperature rises unacceptably high above ambient (say 10-100 C above ambient depending on application).   What are standard values or rules of thumb for the maximum current (or current density) through a pcb via?  PS: the question is about DC, but any additional considerations (if any) for a high frequency current are welcome as well.


Are there any howto guides that show the basic aspects of using SO? It would be nice to have something to link to when telling a user to stop   whenever their  is closed as "not a real question", and to edit the original one instead.  There are other simple howtos that could be useful, such as:   Tagging as homework, and giving efforts so far How not to use a title "CODE PLS!!!!!" Asking on an alternative SE site Commenting instead of posting a new answer Accepting an answer   Even something as simple as a standard screenshot with the various componented (link / button / text boxes) numbered could be extremely useful.  Related to this, what about completely new users who don't see the notifications of new comments? Perhaps it could be possible for a mod to trigger a template email to them?

Can you help me ? I need all solution....


In Two and Half Men, Charlie kept Alan around since they were brothers from the same mother. But why does Walden continue to keep him around? He's certainly not paying rent, helping and certainly not in love! I can understand why he would wanna keep Jenny and her girlfriend around (I mean, who wouldn't?), but why Alan?


How much of Harry Potter was preplanned and how much was improvised?

If we chart out a 2 tiered timeline, the upper tier being the in-universe events and the lower tier being the period in which J. K. Rowling is writing the Harry Potter books, does the lower tier ever out-pace the upper tier?  In other words, as an example, when she wrote Harry Potter and the Philosopher's Stone did she already have the events of books 2, 3, n... sketched out in a notebook somewhere?  It is an exceptionally long series, one which became wildly popular before it was complete. I am very curious how much of it she managed to write ad hoc (stretching it on and on) and when exactly she conceived the final stages of the story.


Tree-like aliens invade Glasgow using mind-control

The general idea of the book was that a race of aliens in the form of trees travelled through space visiting other worlds and using their ability to send their minds into the brains of the creatures living in these worlds so that they could explore without being intrusive or being discovered.   They arrived on Earth and sent their minds into the animals they could sense and one found his mind in the body of a teenage boy in Glasgow, Scotland around the mid-to-late sixties.  Having found himself in the teenager, he discovered the primitive mind of humans had him trapped and unable to return to his tree body.  The story is a little comic and deals with the teenager finding his way in life and how he deals with things like his mother and girls while worrying the others on the ship would be coming for him as he was happy not to rejoin them.


Re-enable secure boot [ MOK secure boot ]

I installed the NVIDIA driver 367.44 from the Nvidia site. As a last step I was prompted to disable secure boot on re-boot. I did that, but I am not fully comfortable keeping it disabled. I want to re-enable it and do not know how to.  In anycase, I can not use the Nvidia card for rendering and it only works with the "--no-opengl-files" option.  Anything else pushes Ubuntu into a log-in loop.  Edit:   sudo mokutil --sb-state   shows:   SecureBoot enabled   But while booting I get an annoying "Booting in insecure mode message"     EDIT: as I understand from the comments this might not pertain to UFEI secure boot, but the MOK secure boot which is needed for Ubuntu to use third party drivers. I am still using 14.04 and keeping the validation enabled did not cause me any issues with my nvidia drivers for CUDA.

What is the purpose of the emitter resistor in a common emitter amplifier?

I'm struggling to understand the purpose of the resistor circled in red, I know it has something to do with DC biasing and the feedback on the circuit (as the capacitor will cause AC bypass). But I'm struggling to understand the exact circumstance where this would be needed. Is it a change in supply voltage, or change in transistor beta? And the exact mechanism that would cause the resistor to solve the problem.


Size of Internet Explorer tile in Windows 8

While the tutorials say you can customise the size of tiles in Windows 8, this is not possible with the Internet Explorer tile. Because this is the tile I most often use I want it to be large, but the tile only has options for small or medium sizes.  Is there any way to make the IE tile large?


Getting the value of a (perhaps un-applied) CSS attribute

I have the following CSS  .EggChart {     width: 5000px;     height: 400px; }   and would like to read the value of height from the CSS class specification, either using raw JavaScript or in jQuery. If the class has been applied to an element of the DOM this seems straightforward: I'd select the elements of the DOM with this class and read their CSS attributes, but if the class has not been applied to any DOM element how would I do this?


Using the Fitch system, how do I prove $((p \implies q) \implies p)\implies p$? I started with the hypotheses $(p \implies q) \implies p$ and $\sim p$. However, from these hypotheses I did not get the desired contradiction to solve the question.  Thanks sb45


I have been using the Java documentation for OpenJDK 1.7, but I am not seeing a lot of information on Big-Oh notation in terms of complexities of operations between different container types, which is making it harder to know which is the most performance collection to use for my task at hand; for example, implementing a stack or a queue.  I have been using an ArrayDeque for both just following my C++ instincts. The basics are there, such as ArrayList is faster than LinkedList, but there doesn't seem to be a consistent section for this. In C++ documentation, there is a section like the one below. Any Javadoc references that speak about complexities between containers would be helpful.  C++ example:      Complexity      Average case constant, worst case linear in the size of the container.   Java Example: Embedded in the ArrayList documentation I found the following     The size, isEmpty, get, set, iterator, and listIterator operations run in constant time. The add operation runs in amortized constant time, that is, adding n elements requires O(n) time. All of the other operations run in linear time (roughly speaking). The constant factor is low compared to that for the LinkedList implementation.


Selecting attribute values with html Agility Pack

I'm trying to retrieve a specific image from a html document, using html agility pack and this xpath:  //div[@id='topslot']/a/img/@src   As far as I can see, it finds the src-attribute, but it returns the img-tag. Why is that?  I would expect the InnerHtml/InnerText or something to be set, but both are empty strings. OuterHtml is set to the complete img-tag.  Are there any documentation for Html Agility Pack?

Why is clicking "flag" in a review immediately counted as failed

In my latest review  I was immediately locked when I accidentally clicked the flag link.  The question how I was able to click the link accidentally can be easily answered with, I did but I don't know either.  Why is clicking "flag" immediately counted as failed even if the flag workflow can be canceled?


Show that this extension is not integral.

We consider $R=\mathbb{R}[x^2-1]\subset \mathbb{R}[x]=R'$ a ring extension, which is easy to see that is integral. Now we consider the ideal $P'=(x-1)$ of $R'$, and $P=P'\cap R$. We claim that $R_P\subset R'_{P'}$ is not an integral extension.   My attempt: I consider the element $\frac{1}{x+1}\in R'_{P'}$. Suppose that this element is integral, then there exists a relation $$ \frac{1}{(x+1)^n}+\sum_{i=0}^{n-1}\frac{1}{(x+1)^i}\frac{a_i}{b_i}=0$$ for $n\in \mathbb{N}$, $\frac{a_i}{b_i}\in R'_{P'}$. Making common denominator and calling $c_n=b_1\cdots b_{n-1}$, $c_i=\prod_{j\ne i}b_j\notin P$, we get $$c_n+\sum_{i=0}^{n-1}(x+1)^{n-i}a_ic_i=0.$$ I think that from here I can deduce an absurd, but I am stucked on this point...


How to prove this problem about Connectivity.

problem:X and Y are topological space. $A \subsetneq X$,$B \subsetneq Y$,$X$ and $ Y$ are connected,then $ X×Y-A×B$ is connected.  I want to use difinition of connnectivity,to prove there no  extist a separation of $ X×Y-A×B$,but I didn't make it.Then i want to use some result about union of connect space to do it as like prove ' a finite product of  connected space is connected',but i don't know how to find connected space such that their union is  $ X×Y-A×B$.


Chances of Getting into Neuroscience PhD program

I have a 3.46 overall gpa ( I'm retaking organic chemistry, so it should be closer to a 3.6 or a 3.7 by the time I graduate) and a 3.7 in my Biology major. My gre scores are pretty shoddy, not gonna lie. While I'm retaking it later on in the month, I'm currently in the 82nd and 86th percentiles for my verbal and writing respectively, but my quant is only in the 30th percentile. I have A's and B+'s in all my math courses, and I even work as a calculus tutor at my school. I have been doing independent research for the past 2 years and I've even participated in a 10 week research program at another university. I'm so worried that I won't get in anywhere. I really want to be out west, either at the University of Washington or OHSU but any funded program that has good research mentors will do. Do I have even a slight chance of getting in somewhere?


I'm sure that I knew how to do this once many moons ago and that it's really simple.  I have a matrix $ X $ which is defined as:  $$ X = A {A}^{T}  $$  How do I find $ A $ given $ X $?


How can I improve portraits when shooting in low light without flash?

I see a lot of questions about low light, and one of them which stood out to me was   All my flash pictures tend to turn out great, but my shots in low light without flash are always terrible   blurry bad colors under exposed   My setup is: Nikon D3200 with a 35mm f/1.8 prime.  After reading the above question, it seemed that I should have gotten a good photo, but below is what I got in RAW. Settings: ISO 800, 35mm, f/1.8 1/15sec.     Can someone give me a suggestion of what my settings should have been, perhaps? (Remember that I don't want to use the flash, so I can capture the ambient). It's typically situations or candid portraits like this I would be taking. Also any advice on what quick adjustments I could make if I get a dim result like below?  I don't want to ask for the subject to stand still until I get a great shot, so if I get a poor result on my first trial, what settings should I immediately switch to in order to hopefully get my second shot closer to a likeable shot?  Note: getting another body or lens would be a last resort if I run out of options.
