I have no idea why this is happening.  I have ran multiple malware programs, I have run anti-virus programs, I even restored to an early point in time.  The keyboard letter "I" doesn't appear to be stuck, I am using an external keyboard by the way.  When I reboot the computer and get to the login screen, when I press ctrl-alt-del to login, it the password textbox starts putting "IIIIIIIIIIII......", it only stops when I bang on the keyboard.  I also noticed at one point that my caps lock on turned caps off and caps lock off turned caps on and some other weird behavior.  I have tried search online for similar issues, but no luck.
I'm using an HP laptop running Windows 7 Home Edition.  The moment I reach the login screen the computer automatically types "ppppppppp" in the password place, luckily I have fingerprint login to counter that.  The moment I login, it keeps acting as if I'm typing 'p' repeatedly. I tried removing the button and cleaning under it but it was no use. I've tried restarting, uninstalling the keyboard driver, but it was no use.  I can't go to Control Panel because the moment I get there, it starts typing "pppppp" in the search field and I'm unable to find anything.  I'm typing this from my phone because going anywhere on my laptop seems impossible.
Directory index forbidden by Options directive Show timestamp of a vote in the tooltip when mousing over it Sometimes I come across an old question or answer that I voted on in the past, but I don't clearly remember when (or sometimes even why) I voted it up or down. Being able to see the date/time that I cast a vote would help me remember my mindset at the time.   When mousing over the toggled vote, the tooltip reads the same as if I hadn't voted, with no further information. For example:     This answer is useful (click again to undo)   The only way to get the timestamp is if I try to click the vote to undo it and get the locked vote message:     You last voted on this answer [datetime] Your vote is now locked in unless this answer is edited   However this requires me to guess that the vote is locked - if there was an edit since then I'll actually undo the vote and erase the info I was looking for.  Feature request: Please add the vote timestamp to the tooltip when mousing over a cast vote. This is already done with the green acceptance checkmark for example. computing the orbits for a group action Let $G$ be the Galois group of a field with nine elements over its subfield with three elements. Then the number of orbits for the action of $G$ on the fields with nine elements is   3 5 6 9   I have no idea how to compute the numbers of orbits for a group action. Anyone please help me. Thanks. What's the difference between denizen, resident, inhabitant? What's the difference between , , and ?  Even if their ODO definitions suggest they are interchangeable most of the time, are there fine differences in meaning between them? Number reference headline I try to number the header of my references. I succeeded to add the number to the table of contents, but I can't get it to work for the header.  To add the number to the toc I used:  \addcontentsline{toc}{section} \protect\numberline{\thesection}References}   If I try the same for \refname, I get 5References without space.   \renewcommand{\refname}{\protect\numberline{\thesection References}}   When I put the references title outside the curly brackets, it's shown in a new line. What am I missing here? The full bibliography call looks like this:  \renewcommand{\refname}{\protect\numberline{\thesection References}} \addtocounter{section}{1} \cleardoublepage \phantomsection \addcontentsline{toc}{section}{\protect\numberline{\thesection}References} \bibliographystyle{apacite} \bibliography{bachelor}   EDIT 1:  As @TeXnician stated, a tilde would solve the problem. It is not very elegant, though, as I have to use approximatly three of them to get the same space as in the other headlines.   \renewcommand{\refname}{\protect\numberline{\thesection~~~References}}   EDIT 2: @Werner suggested a shorter solution, but it throws multiple errors, when I try to integrate it into my .tex file.

Currently, on every other day I commute to work which is a distance of 18km each way. I enjoy this ride but next year I may be moving to a place which will be about 35km from work. Questions:  1) Would it still be reasonable to commute this kind of distance each way once I have moved?  2) Google maps estimates that this distance would take 2 hours to complete. Would it be possible (depending on the bike and fitness) to do this distance in about an hour? How to re-enable tray icons for applications in Ubuntu? Elmah: How to get JSON HTTP request body from error report Why can I modify a read-only file? Short Question:  Why can we manipulate a read-only file in Vim using : + w + q + ! even without being an administrator?  Long Question:  I have a text file (myFile.txt) which is read-only for everyone:  navid@navid-ThinkPad-T530:~/ubuntuTest$ ls -l myFile.txt  -r--r--r-- 1 navid navid 26 Aug 22 21:21 myFile.txt   I can open it with Vim without having admin privileges:  navid@navid-ThinkPad-T530:~/ubuntuTest$ vi myFile.txt    I modify it and press: Esc + : + w + q + Enter and I see this error message:  E45: 'readonly' option is set (add ! to override)   So far, everything makes sense.  But when I press: Esc + : + w + q + ! + Enter, Vim saves the changes.  I'm using Ubuntu 16.04 and VIM 7.4. I'm trying to compile a kernel for a 32bit single-core Intel Atom machine. Needless to say, the compile is taking inordinate amounts of time. It's been going for 2 hours and it's still only halfway through the driver modules.  Compiling a kernel on my main desktop only takes 15 minutes but it's a 64bit machine. Can I cross compile to generate a 32bit kernel package from the better machine? Ubuntu 18.04 bond with netplan duplicate MAC address after cloning If $m^4+4^n$ is prime, then $m=n=1$ or $m$ is odd and $n$ even I have been stuck on this one for months, really simple to state, really giving me trouble.     Show that if $m^4 + 4^n$ is prime, $m&gt;0$, $n&gt;0$, then $m$ is odd and $n$ is even, except when $m=n=1$.   The case $m=n=1$ gives $5$, so that is why it is excluded. Clearly $m$ is odd, for if it was even, the number would be divisible by at least $4$, but I can't seem to get rid of the case where $n$ must be odd.   The only thing I've managed to try is to write $m$ as an odd number, say $m = 2k+1$, and $n = 2\ell + 1$, then get $$ m^4 + 4^n = (2k+1)^4 + 4^{2\ell+1} = 16k^4 + 32k^3 + 24k^2 + 8k + 1 + 4^{2 \ell + 1} $$ and this is congruent to $0 \mod 5$ unless $k \equiv 2 \mod 5$, and now it gives you an even more ugly polynomial if I write $k = 5j+2$, and it's not working. I've tried other inconclusive approaches, like trying to see if two numbers of some form generate numbers of the same form.. (for instance primes of the form 8k+1 and 8k+7 always generate primes of the same form when multiplied together, stuff like that).  Any ideas? Even just ideas you haven't gave a thought... they're welcome! I have a bibliography in which a particular author wrote two papers in the same year.
