Forgot my only administrator account password?
How do I reset the Windows XP Administrator password?
Why won't my computer go to sleep automatically? Windows 8 is set to sleep after 30 mins, and it used to work, but recently it's started refusing to sleep. (I can still manually ask it to go to sleep without any issue.)    I was having issues a while ago, but it was with my network adapter. That's since been disabled, so it's definitely not that:    I've checked to see what devices are able to wake up my machine, but it only appears to be my mouse:    Which is odd, because I haven't recently changed my mouse, and more confusing still: The monitor does go to sleep just fine. If it was actually the mouse keeping my system awake, I'm pretty sure the monitor wouldn't go to sleep.  I've checked my Wake Timers, and nothing:    I've also checked my existing requests...  UPDATE: I found something. What to do with it, I don't know...    Note: Even when /requests says that there's "NONE" under every category, my machine still won't sleep(!).    In short: How can I tell what's preventing my computer from Sleeping?    UPDATE: Ok, so I now have a few more pieces of the puzzle. I came back to my computer and it was ASLEEP! Lawks! It seems that the only times it doesn't sleep is if VLC Player is open, even if a video isn't actually playing.  UPDATE UPDATE: Ok, so it won't sleep sometimes when VLC Player ISN'T running, either. Bah! How to run a fresh version of AIX in a Virtual Machine with a Linux host? Any ideas how to display a PDF file in a WPF Windows Application?

However, I do not fully understand it and was hoping for a better explanation.  The method basically states if you have $x^y \bmod N$, it can be computed by repeatedly multiplying by $x$ modulo $N$:  $$x \bmod N \rightarrow x^2 \bmod N \rightarrow x^4 \bmod N \rightarrow x^8 \bmod N \rightarrow \ldots \rightarrow x^{2[\log y]} \bmod N$$  This is supposed to calculate in $\mathcal{O}(\log_2 N)$ time.  An example is given:  $$x^{25} = x^{11001_2} = x^{10000_2} * x^{1000_2} * x^{1_2} = x^{16} * x^8 * x^1$$  I don't really understand how this is faster. Aren't you just doing the same thing? You're just breaking down the exponents into representations of base $2$. Also where does $x^{2[\log y]}$ come from? If you're breaking it down into exponents of two where does a logarithm come from? (Aren't logs representations of numbers in exponents of $10$?)  I'm sorry if this appears to be a really stupid question - I have minimal knowledge in math.  Also, I wasn't sure if this belongs here or on stack exchange, so give me the word and I'll move it. Why has the role of Bruce Banner been played by different actors in the three films that Hulk has appeared in? Hulk (2003) Eric Bana Bruce Banner  The Incredible Hulk (2008) Edward Norton Bruce Banner  The Avengers (2012) Mark Ruffalo Bruce Banner  Is there any reason why different actors are used in different versions of the same role? How to use Boost in Visual Studio 2010 When should I use double or single quotes in JavaScript? console.log(&quot;double&quot;); vs. console.log('single'); I see more and more JavaScript libraries out there using single quotes when handling strings. What are the reasons to use one over the other? I thought they're pretty much interchangeable.

Modern textbook on statistical field theory with an emphasis on applications to non-equilibrium phenomena? I'd like to make commands I've typed (input) into terminal stand out from all the output.

Go Giants!  bold jumps to mind but I'd accept a color or even highlighting the whole line...   I'm sure there's a way to do this but it's not obvious to me...  thanks! What does it mean when it says under a journal article that it has been communicated by "XYZ" where XYZ is not the author but some other scholar with a very strong reputation? What is the relationship to the actual author and/or the content? Is this some sort of seal of approval to get results out and known quickly? (I am specifically wondering in the context of mathematics and mathematical physics.) I’ve always understood that the phrase two weeks usually turns into two weeks’ when used as a modifier as in   I’m giving my two weeks’ notice.  I get two weeks’ vacation. (“two weeks’ holiday” for Brits)   with an apostrophe on the word weeks’, indicating that the vacation “belongs” to the weeks.   One way to explain this is the phrase “two weeks of vacation” being contracted to “two weeks’ vacation” – the vacation is “of” the weeks; that is, it is possessed by them.  But I’ve seen a lot of people omit the apostrophe in casual writing, and thinking about it, it seems plausible that the noun vacation would be plainly modified by the adjectival phrase two weeks.  But on the other hand, shouldn’t adjectival phrases be hypenated, namely two-weeks vacation?  Yet that seems wrong, too: the hyphenate should be singular, two-week vacation (like two-tone shoes) because .   touches on this (and references a good ) but doesn’t explain why the plural must be possessive in this case.   suggests that two weeks might be adverbial rather than adjectival, and thus resists being used attributively. But that still doesn’t quite explain this particular muddle of pluralization, possession, and attribution.  Given all this, why should “two weeks vacation” be written “two weeks’ vacation” with a possessive apostrophe? How can an 18 month old be taught that bullying is not ok? He seems to like causing the trouble it brings upon him, and bullying, mean acts also seem to please him. He likes to sit on his younger cousin (my son), push him down, and steal his toys. His parents seem to be at a loss about it, and I don't really have any good suggestions to give. Thanks. So...as what do we close too localized questions now? So we got  which works very well and is very nice and handy. But there is one question left, as what do we close ?  It actually helps , "too localized" was removed because it was misused most of the time:     5(A). "Too Localized" is no longer necessary since the specific   off-topic reasons now address its main use case. (new)      Too Localized was, by far, the most misused close reason in our   surveys, with both Community Managers and Moderators deeming over 50%   of randomly sampled TL closures to not have merited closure (including   on SO).      Today, TL is used helpfully on code dump questions on SO, but the new   OT reasons are where this is now correctly addressed. SO can use   "Large blocks of code with requests for debugging without meaningful   supporting info" as a specific OT reason.   But the new dialog leaves us with only four options:        Programming questions are off-topic on Meta Stack Overflow.

Other (add a comment explaining what is wrong)      Only the "other" reason does very well fit on "too localized" questions now, doe we close it with that? Does it make any difference for SEO benefits to buy dropped and already available domains other than backorder domains that are expiring soon?  I heard somewhere that whois gets deleted after being dropped. But I didn't find any confirmation if it's true or not.  Anybody can tell me if there are benefits of one against the other, if yes what? Does iOS have a firewall? Can I use a present-tense verb when writing about a past event? My sentence is     In Charles Dickens' book Oliver Twist, the stingy orphanage director doles out just one small bit of soup to the hungry orphans.   The main question is should it be doles or doled? Could it be either? No Surname in indian passport and given name is considered as last name in E ticket for an international flight I have booked tickets for my parents to visit Mauritius for a week and my mom's passport (given name is xxxx) doesn't have surname, so in the e-ticket form her name has been printed as "Mr xxxx". I have spoken to the travel agency and Air Mauritius, but didn't get any information regarding the issue.  Can anyone please tell me if there might be a problem boarding the flight?  I am very anxious right now since its their first international flight.
