Cannot declare square matrix with large rows/columns (1446) in ANSI C
C programming, why does this large array declaration produce a segmentation fault?
Mean or sum of gradients for weight updates in SGD Will Winterbash promote mass spamming due to its short time frame? Is there any concern that , due to their time-limited nature, will encourage mass spamming of posts? Cosmopolitan, for example, can only be achieved by posting to Meta. There are over one million users on Stack Overflow who may want this hat, and have only until January 4th to get it, and their only means of doing so is to invent some reason to post to Meta. Breadboard Confusion I just received the following breadboard in a electronics starter pack I purchased.    I am a little confused in how I would go about prototyping on this board, all the tutorials I have read state that the breadboard should have a positive and negative  input on it. But it appears this one doesn't.  Could anyone help clear my confusion? Problem in installing Python 3.3 in Ubuntu 12.04 How can I install a package without installing some dependencies?

Need to get 29.3 MB of archives. After this operation, 74.5 MB of additional disk space will be used. Do you want to continue [Y/n]?   I don't want to install the texlive packages. I've installed texlive manually from . Any suggestions? Should I keep my swap file on an SSD drive? I'm considering getting an SSD drive to run as the primary OS partition.  As I understand, this should provide a substantial improvement in performance.     My question is this: Should I leave the swap file on that drive?     The swap partition will be largely random seeks and so should benefit from the speed.  On the other hand, it will be constantly written to which will wear out the drive faster. Is commitment necessary to participate in beta (as of June 2015)? There's this proposal for a new S.E. site which is about to enter the beta phase. It reads  This proposal is in: Commitment A successful site needs people to commit to use it. This proposal is 100% complete. Committed users will be invited to the private beta soon.  I'd like to participate in the beta but I don't want to commit (due to a full name being required). Will I be unable to participate in the beta if I don't commit? Catching poisoned arrows When catching an arrow tipped with poison (like the ones used by yuan-ti) with an ability like the one the monk has or the one given by arrow catching gloves: does the ability reduce the poison damage? If so, is the total damage or the piercing one caused by the arrow only the damage that must be downed to 0 to catch the missile? Tourist Visa (30 days) Dubai valid until date Today I was informed by VFS that my tourist visa for UAE got approved. I'm travelling to UAE on 16th December 2014 and returning on 7th Jan 2015. But when I checked the "valid until" date on the visa it states 30 December 2014.    Does this date mean I should return before December 30th? Should I get it corrected from VFS? What the #$@&%*! is that called? Is there a standard for public key encrypting and signing short messages? Some systems, that operate over flaky bearers, need to send signed, encrypted messages that are entirely self contained - i.e. send a single 300 byte UDP rather than have a 10Kb, two-way, certificate conversation over TCP.  Assume the destination has a private key and already knows the source's public key, and the source has a private key and already knows the destination's public key.  Given this assumption, is there a standard for encrypting/signing a small, but arbitrary length, message?  (I'm well aware of the dangers of rolling my own encryption scheme.)  Would there be a minimum ciphertext size that is related to the public key size?  (I'm thinking plain PKI encryption for plaintexts shorter than the key, and a PKI encrypted AES key for longer plaintexts.) How do I get Skyrim to recognize I don't have a follower anymore? How can I get TeXstudio's syntax highlighting to recognize an unknown command? TeXstudio does not recognize the LaTeX command \rm (red highlighting in the document, with the message: unrecognized command), even after I activate all possible completion files (.cwl).  In such a case, what can I do so that TeXstudio recognizes a certain command for highlighting? "How it works?" vs. "How does it work?" What is the difference between:        "How it works?"      and        "How does it work?" Number of Pairs of Subsets Find the number of Pairs $(A,B)$ of subsets of $[n]$ such that $A ⊆ B$? I just need clarification in my thought process. My professor's wording at times can through me off. I just want to know if I am on the right track. We will have $3$ regions: 1.Outside $B$ 2.Inside $A$ 3. Inside $B$, Outside $A$ I believe the number of pairs is $3^n$ but I am not sure. Any help would be appreciated. Cleaning ‘staining’ off bottom of MacBook screen A couple months ago, I started to see some very small stain spots on the bottom of my MacBook Pro early 2015 screen. It's very annoying to see while I'm using it. When the screen is turned off, I see it as in the picture below. But when it's turned on, I see it as very small water-ish drops. I tried to clean it using water, screen cleaner, and even alcohol, but it didn't go away.  Also that area doesn't feel as smooth as the unaffected area. So, I think it's on the outside of my screen not inside.  Have you ever seen this before? Any suggestions on how to remove it without the need of replacing the whole screen? How can I uninstall a nvidia driver completely ? As expected, Nvidia drivers have reduced my customizations. I can't login to Unity 3D session. I can't find any content to help me to uninstall the driver and I don't know what to do as I have never uninstalled them before. How to solve the diffencial equation for power series $(1+x²)y'' - 6xy=0$ in $x_{0}=0$ I have tried for the power series but when suppose the solution is $y(x)=\sum _{n=0}^\infty a_nx^n$ appeared sums dependents of $a_n$,  $a_{n+2}$ and $a_{n-1}$ and this is not possible. What was the galaxy formation Rust saw before confronting Erol Childress in  S01E08?  It was weird like out of the series. I guess it was some sort of hallucination, a product of Rust's madness or addiction. I just bought a new MTB and am planning to change my previous MTB into a Road Bike.   How do I do it? What kind of parts do I need to change or add or remove?  I am not looking to for a full conversion into specialised road bike. But like the answers are suggesting, I am looking for a bridge between commuter or road bike. My majors concerns to be met are:   Should be fast enough to compete with road racers over short distance Should be light as a road  Should be as close as possible in as cheap as possible.
