So I just came across this question:    And wanted to close it on the grounds that it has absolutely nothing to do with programming. So I click flag-&gt;It should be closed for another reason on the basis that the subheading to that options describes the reason:     This question does not meet this site's standards and should be closed.   So then I click off-topic because... underneath which it says     This question does not appear to be about programming within the scope   defined in the help center.   Yup. Perfect. Then I get a list of options, none of which describes the problems with that post:   Questions about general computing hardware and software are off-topic for Stack Overflow unless they directly involve tools used primarily for programming. You may be able to get help on Super User. Nope, the question isn't about general hardware and software Questions concerning problems with code you've written must describe the specific problem — and include valid code to reproduce it — in the question itself. Nope, not about that Questions asking for code must demonstrate a minimal understanding of the problem being solved. Include attempted solutions, why they didn't work, and the expected results. Nope Questions on professional server, networking, or related infrastructure administration are off-topic for Stack Overflow unless they directly involve programming or programming tools. No, unrelated Questions asking us to recommend or find a tool, library or favorite off-site resource are off-topic for Stack Overflow as they tend to attract opinionated answers and spam. No... This question belongs on another site in the Stack Exchange network. Errr... Maybe but do they really want it???   So what am I supposed to do, just send it off to someone on some other Stack Exchange site? Why would this list not be exhaustive?
Currently, when flagging an off-topic question, the following choices are offered.   Questions about general computing hardware and software are off-topic for Stack Overflow. Questions concerning problems with code you've written must describe the specific problem and include valid code to reproduce it. Questions must demonstrate a minimal understanding of the problem being solved. Questions on professional server, networking, or related infrastructure administration are off-topic for Stack Overflow unless they directly involve programming or programming tools. Questions asking us to recommend a tool, library or favorite off-site resource are off-topic for Stack Overflow as they tend to attract opinionated answers and spam. This question belongs on another site in the Stack Exchange network   However, there are some questions that fit in none of these categories.  For example, career advice questions are off-topic here (and on programmers.SE), questions like  are off-topic on pretty much any SE site.    Some questions might also be relevant on another SE site not listed when the "belongs on another site" option is selected.  How should those questions be flagged?  Why isn't there a "it's off-topic because it is" option?  EDIT: just to be clear, I don't have the "Other" option under Off-Topic.
How to make pdfsam work in (L)ubuntu 18.04? In the radio series, how did Zaphod get into the artificial universe? In the book The Restaurant at the End of the Universe, it's very clearly explained how Zaphod gets into the simulated universe; he's in it from the moment he enters Zarniwop's office, and a big deal is made of him leaving via the window rather than the door so that he stays in it.  In the radio series, however, this doesn't happen. At the end of Fit the Seventh, Zaphod asks "How do we get to this universe, then?" and Roosta replies "I'm afraid it looks like we don't...", pointing out that the building is splitting down the middle, preventing them reaching the office.  Later, in Fit the Twelfth, Zaphod finally meets Zarniwoop in the lounge of the slightly-delayed spaceliner and reacts with astonishment at learning he's been in the artificial universe all this time. "How did we get into it? I mean like where, when?"  Zarniwoop only replies enigmatically: "You didn't notice? Well, I'll let you work it out for yourself."  So, how did he get in? As noted, he never actually entered Zarniwoop's office. My only thought is that it happened during the "body debit" incident with the disco, but there's no particular indication that that should be the case. Is there any other possibility? How to determine whether a given Linux is 32 bit or 64 bit? When I type uname -a, it gives the following output.  Linux mars 2.6.9-67.0.15.ELsmp #1 SMP Tue Apr 22 13:50:33 EDT 2008 i686 i686 i386 GNU/Linux   How can I know from this that the given OS is 32 or 64 bit?  This is useful when writing configure scripts, for example: what architecture am I building for? How to setup synctex with vim, pdflatex and an open-source PDF-viewer under Linux? Accidentally ejected External drive while downloading file, now having problems reading With $x+y\ge z$ $(x,y,z\ge0)$, prove that: $$\frac{x}{1+x}+\frac{y}{1+y}\ge\frac{z}{1+z}$$  I'm aware that using analytic view this is easy since $f(x)=\frac{x}{1+x}$ is concave in $[0,\infty)$. However I want to prove it using merely algebraic techniques. Is that possible? How to set default magnification for all windows 32-Bit UEFI Boot Support I recently purchased a Dell Venue 8 Pro.  I have read online about what it needs in order to boot into Ubuntu or any other Linux distro.  From what I have gathered, what really needs to happen is 32-bit UEFI support.  I got information from several sites, but where it was really summed up was in this previous post:    "Ubuntu has no 32-Bit Uefi installer, ask them to add support, they may listen."  That thread was specifically about getting the Dell Venue 8/11 Pro to boot Linux.  However, there are a slew of new tablets coming out running 32-bit UEFI, and I think this is a trend that is going to continue to grow:  mjg59.dreamwidth.org/26734.html  "UEFI on IA32 isn't going away. It will show up on more embedded systems as time goes on."  Others have tried this before with mixed success, but haven't gotten things to work quite right:    "It doesn’t really work. But it’s interestingly close."  I'm trying to start a thread dedicated thread on 32-Bit UEFI support, because that is the piece that is missing (from what I understand).  I don't really know how to work with this stuff, but I'm hoping that some people who do will read this and either contact canonical or somehow patch Ubuntu (or any other distro, really) to work this way.  Again, I don't really know how to do any of this...I'm just hoping someone can help!  Dell Venue 8, 11 Pro, Toshiba Encore, Acer w3, w4, Lenovo miix, and the asus transformer a100 are all tablets that will be affected by this...I think these are going to be incredibly popular tablets once their prices go down, and I think people are really going to get interested in putting linux on these.  Any help is appreciated, and thank you all so much!  EDIT 4/1/14:  Just booted into Ubuntu on my DV8Pro!  All you have to do is follow the instructions here:    To summarize, what you need to do is download the latest Ubuntu 14 daily build (AMD 64 is what worked for me) and put that on a USB drive via Rufus.  'For “Partition scheme and target system type”, choose “GPT partition scheme for UEFI computer.”' You can get the latest daily build here:   You will need to put the file found below into your EFI/Boot directory:   Disable Secureboot and such--follow the original instructions link if you don't know how.  Then set the USB to boot first in BIOS.  This should get you to GRUB.  The rest I'll quote the original author, it's real straightforward:  In the GRUB menu, highlight “Try Ubuntu”, and press “e” to edit it. In the editing screen, scroll down to the command line options, where it says “quiet splash”. Delete “splash” and replace it with: video=VGA-1:1368x768e reboot=pci,force [EDIT: For those of us using the Dell Venue 8 Pro, you need to use this line instead: video=VGA-1:800x1280e reboot=pci,force That accounts for the different resolution of screen.]  Then press F10 to boot. You should get all the way to the Desktop.  There you have it!  This got me to the Unity Desktop.  Problems:  Wifi is not working, but I used an Ethernet adapter and that seems to work.  I tried rotating the screen, but it throws your touch input off to one side, so I left it.    Make sure to read the tutorial mentioned earlier, it is more comprehensive, even though it is made for the ASUS T100.  If nothing else, the instructions I have provided should be enough just to get you to the Unity Desktop, which for me was amazing!  Hope you too can have the same success and keep building on it!  For what it's worth, someone else did this and posted a youtube video here: When should "Mom" and "Dad" be capitalized? I am trying to understand capitalization rules with Mom and Dad. I believe I have it correct below, but please let me know if I do not.     The one thing I learned from my dad was that it was good to earn the trust of one's children. Dad has shown me how good that a dad can be. One day when I went to his house, and Dad wasn't there, I ran outside....   The above passage is just made-up just so that you would see what I mean about capitalization. Let's put numbers by each one, like so:     The one thing I learned from my dad(1) was that it was good to earn the trust of one's children. Dad(2) has shown me how good that a dad(3) can be. One day when I went to his house, and Dad(4) wasn't there, I ran outside....    This is one where I'm not certain. I believe in this sense I'm showing possession here with "my", and it just didn't seem right saying "my Dad". I don't know what the grammar rule is here, or if I even have it right. This one is obvious—it starts the sentence. In this case, I'm using Dad like a name instead of saying "Larry". Therefore, it should be capitalized. Again, just like 3. In logic, a semantics is said to be compact iff if every finite subset of a set of sentences has a model, then so to does the entire set.   Most logic texts either don't explain the terminology, or allude to the topological property of compactness. I see an analogy as, given a topological space X and a subset of it S, S is compact iff for every open cover of S, there is a finite subcover of S. But, it doesn't seem strong enough to justify the terminology.   Is there more to the choice of the terminology in logic than this analogy? How to pin either a Shortcut or a Batch file to the new Windows 7, 8 and 10 Taskbar and start menu? We are having trouble adding our batch scripts to the Windows 7, 8 or 10 taskbar or start menu.  Our batchfiles take some arguments and just execute other application based on those arguments . To keep it simple, we created some shortcuts for our customers which they just need to click in order to get everything running.  The question here is: How can we pin those shortcuts or batch files to the taskbar or start menu?  (The customers aren't supposed to access the file system and that's why they can only see the taskbar) Parsing XML, JSON, and newer data file formats in UNIX using command line utilities The Unix environment has some excellent tools for parsing text in various forms. However, of late, the data is not in the traditional (historical) formats (CSV, TSV, record-based or some other delimiter-based) it used to be before. Data these days is exchanged in structured formats like XML/JSON.  I know there are some good tools like sed, awk and Perl which can chew down nearly any form of data out there. However, to work with this sort of structured data, often one has to write a complete program, and, given the little time available to extract information, one has to sit down and figure out the whole logic of what one wants to query and put it down programmatically. Sometimes this is not OK – basically because the information extracted from those files acts as inputs for further work; also because of the time it takes to search for the appropriate solution and code it up. A command line tool is needed with sufficient switches to find, query and dump data.  I'm looking for tools that take a XML/JSON or other forms of structured data and dump it into other formats like csv, etc., so that from there one could use other commands to get any information out of it.  Are there any command line utilities you know of which do this kind of a job? Are there already awk/Perl scripts available to this? Let I and J be ideals of a ring R. Show by example that the set of products {xy | x ∈ I, y ∈ J} need not be an ideal Let I and J be ideals of a ring R. Show by example that the set of products {xy | x ∈ I, y ∈ J} need not be an ideal, but that the set of finite sums of products of elements of I and J is an ideal. This ideal is called the product ideal, and is denoted by IJ.   I want to check if my work on the first part makes any sense. I am not sure if I am picking the right example.  If I let R = Z and I = (2) and J = (3) then I has multiples of 2, and J has multiples of 3  6 will divide the product IJ if we add 2 and 3 though we get 5 in IJ, but I am not sure if 5 Divides IJ. How to add modifiers using python script and set parameters? I've found some code that could add a modifier but none can set parameters like Octree. How to auto populate with conditions? My DOM looks like this:  &lt;div id="d1"&gt;    &lt;div class="c1"&gt;             &lt;a href="#"&gt;&lt;img src="img1_on.gif"&gt;&lt;/a&gt;             &lt;a href="#"&gt;&lt;img src="img2_on.gif"&gt;&lt;/a&gt;    &lt;/div&gt; &lt;/div&gt;   When someone clicks on an image, I want the image src to change to &lt;img src="imgx_off.gif"&gt; where x represents the image number 1 or 2.  Is this possible or do I have to use CSS to change the images? Error: !

I created a virtual machine to install ubuntu 14.04 on VirtualBox 4.2.12.*. I created virtual CD to install it with fixed-size virtual disk of 200GB. After successful installation, it restarted as usual. But after showing message of below, it hangs. Actually, I created virtual machines to install ubuntu at Virtual Box successfully several times. It's very easy. The installed ubuntu versions ranged from 9.10, 13.04 and even 14.04 before. I don't know why this time it hangs at restarting after successful installation. The only difference between this failure restart and previous successful ones is that the virtual disk is much larger, 200GB. It failed three times.  * Deactivating swap...

In the event of a power failure, the LED bulb will turn ON automatically. That is, when the switch is ON and mains power goes off the bulb will detect that and turn ON. If the switch is OFF bulb will not turn ON. When mains are ON and the switch is ON the bulb will start recharging again.  It is just like a normal bulb. See the   My question is, how the bulb will detect the event of mains failure? Can somebody give me a hint on this?
