I want to update my windows 10 to the latest build 1607, I have 5 laptops at home which needs this update, I would like to download the ISO (or whatever the file extension is) and update them manually instead of downloading the same build 5 times, I found this  but it gave me a desktop client app that downloads the same file, (like scratching your left ear with your right hand!), I want the actual update files maybe direct link or the location where this downloader stores the updates.
I need to repair my Windows 10 installation. Where can I get a clean ISO (with install.wim, no Install.ESD, so that I can run DISM against the WIM) of the specific Windows 10 build required for this?  In my case, I need the Anniversary update (Build 14393), Creators Update (Build 15063) or Fall Creators Update (Build 16299.15).
Why is my Nikon 50mm f/1.8 giving me an fEE error? I have a AF Nikkor 50mm f/1.8. When I have the aperture setting on the lens to 22 I can take photos. But when I change the dial to anything other than 22(lowest f/stop) then I get a flashing fEE message and r09 where the number of exposure left is.  I don't have the manual for this lens but am just wondering if anyone knows what the issue is here.  My camera is a Nikon D70S. Exact sequence of sheaves with non exact sequence of global sections Let $X$ be some topological space. By $\mathcal{F}_i$ we denote some sheaves of abelian groups on $X$. The sequence of sheaves and morphisms  $$\mathcal{F}_1\longrightarrow \mathcal{F}_2\longrightarrow \mathcal{F}_3\longrightarrow... $$ is said to be exact if for each $x\in X$ the corresponding sequence of stalks $$(\mathcal{F}_1)_x\longrightarrow (\mathcal{F}_2)_x\longrightarrow (\mathcal{F}_3)_x\longrightarrow... $$ is exact. However if the sequence of sheaves is exact than the sequence of global sections is not necessarily exact! (The most famous example is the sequence of sheaves $$0\longrightarrow\mathbb{Z}\hookrightarrow \mathcal{O}\stackrel{\exp}{\longrightarrow} \mathcal{O}^*\longrightarrow0$$ considered as sheaves on $\mathbb{C}-\{0\}$, where $\mathcal{O}$ is a sheaf of holomorphic functions, $\mathcal{O}^*$ is a sheaf of holomorphic functions with no zeros).  So, could you give me some easy examples of such phenomenon ? How to get Saudi Arabian transit visa for road travel? Recover data from hard drive with partitions (but not most data) overwritten I have a 500GB hard drive I've been keeping around to recover data from that I removed from a failing NAS drive that got sort of... erratic at the end. I finally got rid of the NAS when during a firmware update it removed the partition table.  Fast forward to a week ago, when I was building a new PC, and a mixup resulted in me placing the hard drive in question in the new PC and installing Windows XP on the first 100GB. I'm presuming any data on that first 100GB is now gone, but for the rest of it, is there any way I can recover it at home, as professional data recovery is currently too expensive?  I have a blank 1TB HDD if I can store any images of that hard drive on. The problem was definitely with the NAS and not the hard drive, as the hard drive had a successful install of Windows when mistakenly place in the new PC, and there were capacitors in the NAS's circuitry clearly broken.  The data I want to recover (in order of priority) is:   High: Some jpgs of family photos. Medium: Some RAW files. (There are also jpg versions of all of these) Low: Some mp3s, avis and ISOs, I can re-rip most of these if need be, but it'd be handy not to have to.    (I don't need a backup lecture, and if you can hold it in from nagging Jeff Atwood for it, you can hold it in from nagging me for it)  In short:   The partition tables are gone and overwritten. The data is not overwritten, except for an amount equal to the size of a Windows XP SP3 installation. I want to do a survey of textbooks in set theory. Amazon returns 3582 books for the keywords "set theory". A small somewhat random selection with number of references in Google scholar is the following.   Two questions:    What textbooks in set-theory are considered standard?  What is a good place to aggregate standard references (of textbooks)?    (I'm only interested in text-books, which as a format already provide a kind of standardization)  Textbooks on set theory (author: title (year) #Google Scholar citations )   Thomas J.

(Some of the dates might not be the first published edition.) Why is it string.join(list) instead of list.join(string)? Would a Bayesian admit that there is one fixed parameter value? In Bayesian data analysis, parameters are treated as random variables. This stems from the Bayesian subjective conceptualization of probability. But do Bayesians theoretically acknowledge that there is one true fixed parameter value out in the 'real world?'  It seems like the obvious answer is 'yes', because then trying to estimate the parameter would almost be nonsensical. An academic citation for this answer would be greatly appreciated. What do I do now if I contributed to Roth IRA in 2012-2013 and my MAGI exceeded the limit? In 2013 I opened a Roth IRA for year 2012, contributing $4000 for year 2012.   In 2014 I contributed $5500 to that same Roth IRA for year 2013.  In 2015, I realized I was not eligible to contribute to a Roth IRA in 2012 and 2013 due to MAGI exceeding the limit. I opened a new account (Traditional IRA), deposited $5500, then immediately did a conversion to a new Roth IRA. (This is the "backdoor" approach as I understand it, is perfectly legal, and what I should have done in previous years). So I believe my Roth IRA account #2 (for tax year 2015) is in good standing  So now, what exactly should I do with the first Roth IRA account that I contributed to (incorrectly) for years 2012-2013? Luckily (?) there is only about $500 of gain in the account at this time.  If I re-characterize it as "Traditional IRA", have I missed the opportunity to do the conversion to Roth IRA for years 2012 and 2013?  Out of curiosity: Had I not caught this error, what would be the implications at Retirement time when I tried to take money out of the Roth IRA? Would the funds be treated as ordinary income (plus penalty?)   Lastly, with all this seemingly "fancy footwork" opening Traditional IRA and converting to Roth IRA, what documents (if any?) do I need to hold on to when it comes time to withdraw from the Roth IRA at retirement time to ensure the tax-free benefit?

I used to think that it's mist, but from what I've read here, it turns out that it isn't.  It's the white smoke-like fog that is close to the ground. I've seen it recently above a couple of small ponds (and ground) in a damp forest. It was almost as white as smoke, you can barely see through it, but it is close to the ground, from 20cm to a meter or so.  Since it isn't fog (which is a cloud that you can see, say from a mountaintop, and if it's not mist (which is more like 'rain'), then what is it? How to show textures in the 3D View editor? Is there any software or hardware which lets you stop, slow down, speed up or even reverse time? Obviously I'm talking about time in terms of the PC clock rather than real time.  We were testing an application we've developed at work by setting the clock forward and back to simulate different scenarios and I started thinking how useful it would be if you could adjust the rate(?) of the system clock with finer control. So you could make a minute pass in a second or a day pass in 30 seconds and watch how the program you're developing copes with changes in date and time.  Is there any such software available?   I'd be interested to hear if anyone knows of any software or hardware which can let you do some or all of the above. I am working on binary classification problem, I try to evaluate the performance of some classification algorithms (LR,Decission Tree , Random forest ...).

The human bodies, as we've seen, are kept in tanks and the body is kept asleep.  But why did the Matrix need to provide any kind of simulation for the brain to experience?  Why couldn't it have just kept all humans in a medically induced coma?  Or performed something equivalent to a lobotomy on every human?  Why did the Matrix need to spend the resources to keep the humans in good mental shape?
