When applying for post-doctoral and faculty positions you are typically asked for three (sometimes more) reference letters to support your application.    Given that it is competitive out there, it also makes sense to apply for all positions that are good matches to your qualifications and career development goals (in the case of post-docs).  Sometimes this may mean asking for several reference letters (or pre-application "can you support me if required?" requests) in a short space of time.  Also, there may only be a small pool of people (i.e. 3 or 4) who know your work sufficiently well to give an excellent reference.  I have also been told that referees want to help you out, and that there is no reason to fear asking them.  And, that in many cases once a letter is written it can typically be quickly repurposed.  But there must be a breaking point.  How do I manage this without being disrespectful?  How many requests in a given unit of time is too many, or harms my credibility?   I am asking this question in this forum, as I am interested in the norms in the academic world, which are often somewhat different than the rest of the working world. Proving an integral equation.

Stack Exchange app iPhone X optimization The Stack Exchange app doesn’t look very good on Apple’s brand new flagship phone yet.    Also the app can’t identify the device model either.

The wrapping is really ugly and I can't, for the life of me, find a fix that doesn't involve manually tweaking the hell out of everything, to the point that I might as well scrap the crappy algorithm packages and write everything out in TeX.  Is there any way to properly indent the following  \documentclass{article} \usepackage{algorithm} \usepackage{algpseudocode} \begin{document} \begin{algorithm}    \caption{My pseudo code.} \begin{algorithmic}[1]    \While{this line is sooooooooooo long and boring and too much for algorithmic to handle}       \State look at this state, this state is just too long for algorithmic to display it properly        \While{again this line is sooooooooooo long and boring and too much for algorithmic too handle}          \State look at this state again, this state is just too long for algorithmic to handle, I'm just going to switch to Word       \EndWhile    \EndWhile \end{algorithmic} \end{algorithm} \end{document}​     so that the output is similar to I'm using Ubuntu 16.04 and there's no fglrx! Block any query in BIND I've been trying to block ANY queries in my BIND server with no success.  I followed this post  which says that I can use minimal-responses but it doesn't work.  None of the answers fit my current configuration.  view world {     match-clients   { world-clients; };     allow-recursion { none; };     recursion       no;     allow-transfer  { key XXXXXX; };      minimal-responses yes;      forwarders      { };      include         "/etc/bind/world.conf"; }; Site blocked by content filter I run a large and high trafficked WordPress powered platform. One of my editors informed me that our site is blocked at his workspace as a "games site". They use WebCat to filter the traffic.  The issue here is that our platform is not a gaming site, although it does have a games category that covers news. And that is a very minor part of the site.  My question is, what can I do to unblock the site? How does WebCat work? Do they use a universal database to filter the traffic (meaning that the site is blocked on all workspace with WebCat) etc. Obviously they need to improve their filtering algorithm. Get complete stats of process started/terminated during login of user account When I login, I notice many process quickly start and terminate in task manager. But it happens very fast and I cannot save details about them (like process name, command line, CPU usage,..)  How can I collect stats about them so I can view them later My new laptop came preinstalled with Windows 8. Naively, as I am, I just formatted the harddrive and installed fine old Ubuntu. Now I want to install Windows 8 for dual boot again, but I have no DVD and to download the ISO one needs a product key. That key is not on the back of the laptop anymore but somewhere on the mainboard.  Is there any way to recover the product key from the mainboard using Ubuntu? Suppose a book consists of three sections:     The book is/was divided into three sections.   I am thinking the past tense option "was" should be used, because the act of dividing the book into three sections happened at the time of writing. Is my analysis good? My computer wont shutdown If I try to shutdown my computer it simply takes me back to the login-screen. I looked around and found :  Type in terminal:   sudo gedit /etc/default/grub Find the line: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" Change this to:GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force" Save the file and close the file.  Finally, in terminal: sudo update-grub   But now there is a new problem when I try step 5 it says:  *myname*@ubuntu:~$ sudo update-grub [sudo] password for *myname*:  /usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?). *myname*@ubuntu:~$    I am new whit linux and dont know what to do.

Capturing Blue Screen of Death (BSOD) screen Possible Duplicate:          Sometimes I get a BSOD screen for a split second and I have no chance to see the cause of it. It also happens when I am not at the computer. The event log doesn't have enough information. Is there a way or tool that captures the screen when it happens so I can look at the cause later.  I already did a memory diagnostics test so that's not the problem. I am using &lt;a&gt; tags for links on a web page. How do I disable the Tab key from selecting either of them? My floating point number has extra digits when I print it How to find all questions that were duplicates of another question? I am interested to see a list of all questions that were closed because being a dup of another question.  I strongly want to research a particular question and reading all the answers inside the dups will help me a lot.  Is there such feature? if not, this is a feature request
