• How to make bottom half of a page take up remaining height?

  - by RobVious

  I've searched and tried a bunch of different things. I have a variable-height tophalf, and the bottom half should fill up the remaining space. A JSfiddle: http://jsfiddle.net/UCJmQ/ CSS: .top { background-color: lightblue; height: 300px; } .bottom { background-color: green; min-height: 100px; overflow: hidden; height: 100%; } html, body { height: 100%; } HTML: <div class="top"></div> <div class="bottom"> </div> What I'm seeing now is the green page taking up the entire window's height, not the remaining height. How can I make it take the remaining height instead?

• PHP - Setting Database Info

  - by user1710648

  First off, I'm sorry if this shows no code which is not what Stack Overflow is about..But I have no clue where to go on this. I have a basic CMS I made, and I am trying to distribute it. I want to make it so that upon going to /cms/install for example, they set the database info, and different info to integrate into the CMS. Now my issue is, what would be the best method to allow the user to store that database info? A cookie seems to not be the right way..Could I store database info inside of a database? Not too sure where to go on this. More or less. What is the best way to temporarily store the database information the user gave before arrival of the full CMS.

• How are OpenGL programs debugged?

  - by manasij7479

  I'm trying to find what is causing a segfault when glDrawArrays is called (as gdb says) in my simple program. When I use the OpenGl calls directly, the program runs fine. But when I wrap them up into two classes (under construction, of vao and vbo) the program segfaults. So, in my wrappers, I definitly disabled something or set something I'm not supposed to. My question is, how do I get some diagnostics that will help me pinpoint the source of the problem ? I'm looking for something similar to what glGetShaderiv does, but for vao and vbo s, that will tell me if I have..say.. unbound a buffer by mistake. [I'm not posting the code here, but if any of you want to donate some time by testing a segfaulting example, here is a tar.gz of the source . You'll need working libraries of sfml-2.0rc, glew and gcc=4.6 .]

  After an error occurs, I call perror(), naturally. But I'm getting a segmentation fault when I do this or printf("error: %s\n", strerror(errno)); I have no idea what is happing. int fd; if((fd = open(FILENAME, O_RDONLY)) == -1) { perror("fbi"); exit(1); } for(;;) { readed = read(fd, buffer, BUFSIZE); if(readed == 0) break; if(readed == -1) { perror("fbi"); // <- here's the error exit(1); } How to fix this?

• Synchronization between user space process and interupt context code

  - by user1748950

  Recently I attended couple of interviews. Out of all kernel questions which were asked, thr is one specific question which I couldnt find convincing answer of. How will you use different synchronization techniques while sharing data between user space process and interrupt context function? My convincing answer was: In interrupt context code: 1. do *spin_lock_irqsave* 2. access data buffer which is shared between user space app and kernel 3. do *spin_lock_irqrestore* Then this was not convincing answer. Do I have to do irqsave and irqrestore in all the instances of data access? Regards, Yogi

• What is the best way to go about obfuscating Java code? [closed]

  - by Waltzy

  Possible Duplicate: Best Java obfuscator ? Well, I'm planning on releasing a Jar into the world but would prefer if the code was not readably available to anyone with a Java Decompiler as I want to control access to the program with usernames / auth codes etc. After some Googling I haven't found any software to do this for me, so I was wondering what steps to take from here; if anyone can point me at any software or information on methodologies of obfuscation I would be grateful. Cheers again Stack Overflow.

• poll(2) doesn't empty the event queue

  - by sasayins

  Hi, Im using linux as my programming platform. I am using poll(2) to know if my device is triggering an event. The first call of poll is ok, it blocks and wait for the event to happen. But in the second poll function call, it will return but it capture the event. Below are my code ret = poll( fds, 1, 2000); //2 secs timeout if( fds[0].revents & POLLIN && ret > 0) { printf("event occur\n"); } It seems the queue/buffer is not empty, im just assuming. What do you think is the problem? Thanks.

• IE7 cutting off image

  - by Kimberley

  Hi all I have 3 divs with rollover images inside them stacked vertically inside my main content div. IE7 is chopping off about three quarters of the bottom div and I can't figure out why. It displays perfectly in all other browsers (even IE6) but IE7 just won't display properly. This is my first website so I still have a lot to learn. I've managed to fix the other IE bugs but just can't figure this one out. Any help appreciated! } .main_content { float: left; width: 816px; background-image: url(Images/evokedesign_bg_tile.png); background-repeat: repeat-y; overflow: hidden; } .portfolio_buttons { float: left; width: 634px;

• How to fill a structure when a pointer to it, is passed as an argument to a function

  - by Ram

  I have a function: func (struct passwd* pw) { struct passwd* temp; struct passwd* save; temp = getpwnam("someuser"); /* since getpwnam returns a pointer to a static * data buffer, I am copying the returned struct * to a local struct. */ if(temp) { save = malloc(sizeof *save); if (save) { memcpy(save, temp, sizeof(struct passwd)); /* Here, I have to update passed pw* with this save struct. */ *pw = *save; /* (~ memcpy) */ } } } The function which calls func(pw) is able to get the updated information. But is it fine to use it as above. The statement *pw = *save is not a deep copy. I do not want to copy each and every member of structure one by one like pw-pw_shell = strdup(save-pw_shell) etc. Is there any better way to do it? Thanks.

• DIV appear differently in chrome only.

  - by DreamWave

  I have a website at bgflirt.com that appears differently in FireFox and Chrome. This is how it looks in firefox: and here's how it looks in chrome: As you can see, in chrome (and safari) the page is not stretched to fit the entire screen. I'm using this code for positioning the div containing the flash on the right: <div style="width: 200px; position: absolute; right: 0px; top: 10px; overflow: hidden;"> </div> The page should look the way it does in firefox, in all browsers. Any ideas on how to fix this will be greatly appreciated !

• conditional beginReceive

  - by sbenderli

  I am writing a client program that uses Sockets. I would like the client to receive asyncronously UNLESS it is expecting a response, in which case I would like to receive syncronously. My current problem is that because I have to make a call to socket.BeginReceive which waits until there's data on the buffer, the async call always happens prior to the sync call.. How could I temporarily stop BeginReceive from executing? Is there a way to call EndReceive and then once I am done receiving syncronously, I can continue to receive asnycronously?

• Setting height of a DIV to correspond with location of anchor inside said DIV

  - by filip

  Core issue : http://jsfiddle.net/pipip/P46Xg/ I have a div container with a few paragraphs of text, and inside one of these paragraphs is the following anchor <a id="stop" /> The container is set to overflow:hidden Is it possible with javascript / JQuery to set the height of the container so that the bottom of the container stops exactly at or below the anchor? Added Depth & Background : http://jsfiddle.net/pipip/yj9dB/ This would be used for a modified JQuery Slider. Where someone using a CMS could type [readmore] anywhere into the Content field, which would be replaced by the above anchor via PHP. This way they would be easily able to control where the Read More break appears within the container. In the associated example I am hard-coding the height to 75px, although what I want is for the height to be dependent on the location of the anchor id="stop" in the text. Thanks. If this is an awful way to go about it, I'm all ears!

• Alignment issues with IE7-8

  - by user1868861

  I have major issues with cross browser compatibility. This picture illustrates the problem: What code do I put in for IE7-8 so that my menu aligns properly? Right now it looks right in firefox but nothing else. This the the menu code she had (there might be other code associated but I don't know, see actual site): .custom .menu { height:25px; border: 1px none; float:right; } I have tried things mentioned in other threads, overflow:hidden; / giving a width / margin: 0 auto etc. Nothing works and only ends up breaking Firefox as well.

• Reference and Value confusion

  - by rgamber

  Hi I read this question on Stack overflow, and tried to do an example. I had the below code: public static void main(String[] args){ int i = 5; Integer I = new Integer(5); increasePrimitive(i); increaseObject(I); System.out.println(i); //Prints 5 - correct System.out.println(I); //Still prints 5 System.out.println(increaseObject2(I)); //Still prints 5 } public static void increasePrimitive(int n){ n++; } public static void increaseObject(Integer n){ n++; } public static int increaseObject2(Integer n){ return n++; } Does the increaseObject print 5 because the value of reference is changing inside that function? Am I right? I am confused why the increasedObject2 prints 5 and not 6. Can anyone please explain?

• Javascript for removing menu and scroll bars

  - by nWight

  Hi - I have this script on my html page: parent.resizeTo(550,510); I'd like to add to it so it positions the window in the middle of the screen. Also, I want to remove the address and tool bars (I've managed to hide the scrollbars by using body{overflow:hidden;}). I know how to do this using JS upon opening a new window from the browser but this needs to work from clicking a link on a PDF. Does anyone have any suggestions? Thank you!

• C++ vector that *doesn't* initialize its members?

  - by Mehrdad

  I'm making a C++ wrapper for a piece of C code that returns a large array, and so I've tried to return the data in a vector<unsigned char>. Now the problem is, the data is on the order of megabytes, and vector unnecessarily initializes its storage, which essentially turns out to cut down my speed by half. How do I prevent this? Or, if it's not possible -- is there some other STL container that would avoid such needless work? Or must I end up making my own container? (Pre-C++11) Note: I'm passing the vector as my output buffer. I'm not copying the data from elsewhere.

• Error 2013: Lost connection to MySQL server during query when executing CHECK TABLE FOR UPGRADE

  - by Dean Richardson

  I just upgraded Ubuntu from 11.10 to 12.04. My rails app now returns the (passenger) error "Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (111) (Mysql2::Error)". I get a similar error when I try to access mysql at the command line on my Ubuntu server using mysql -u root -p. I have mysql-server 5.5 installed. I've checked and mysql is not running. When I try to restart it, it fails. Here are some key lines from the tail of /var/log/syslog after an attempted restart: dean@dgwjasonfried:/etc/mysql$ tail -f /var/log/syslog Mar 7 08:55:27 dgwjasonfried /etc/mysql/debian-start[5107]: Looking for 'mysqlcheck' as: /usr/bin/mysqlcheck Mar 7 08:55:27 dgwjasonfried /etc/mysql/debian-start[5107]: Running 'mysqlcheck' with connection arguments: '--port=3306' '--socket=/var/run/mysqld/mysqld.sock' '--host=localhost' '--socket=/var/run/mysqld/mysqld.sock' '--host=localhost' '--socket=/var/run/mysqld/mysqld.sock' Mar 7 08:55:27 dgwjasonfried /etc/mysql/debian-start[5107]: Running 'mysqlcheck' with connection arguments: '--port=3306' '--socket=/var/run/mysqld/mysqld.sock' '--host=localhost' '--socket=/var/run/mysqld/mysqld.sock' '--host=localhost' '--socket=/var/run/mysqld/mysqld.sock' Mar 7 08:55:27 dgwjasonfried /etc/mysql/debian-start[5107]: /usr/bin/mysqlcheck: Got error: 2013: Lost connection to MySQL server during query when executing 'CHECK TABLE ...

Dean Richardson Update: Thanks to quanta's suggestion, I looked at the /var/log/mysql/error.log file. I found error messages relating to pointers, fatal signals, and more stuff that I really couldn't make much sense of. I also found mysql man page references, however. One suggested that I try starting mysqld with the --innodb_force_recovery=# option, then attempt to dump (or drop) the offending/corrupted database or table. I worked through the escalating option levels one-by-one (innodb_force_recovery=1, innodb_force_recovery=2, etc.) This allowed me to successfully run mysql -u root -p from the command line and execute several commands. I was able to run queries on my production database, but any attempt to query, dump, or even drop my development database raised an error and led to me losing the connection to mysql. So I've made progress, but until I'm somehow able to drop or repair my development db I'm still unable to get my app to load. Any further advice or suggestions? Thanks! Dean Update: Right after running sudo mysqld --innodb_force_recover=1 from the command line, the error.log contains this: Right after retrying sudo mysqld --innodb_force_recover=1, The error.log file shows this: 130308 4:55:39 [Note] Plugin 'FEDERATED' is disabled. 130308 4:55:39 InnoDB: The InnoDB memory heap is disabled 130308 4:55:39 InnoDB: Mutexes and rw_locks use GCC atomic builtins 130308 4:55:39 InnoDB: Compressed tables use zlib 1.2.3.4 130308 4:55:39 InnoDB: Initializing buffer pool, size = 128.0M 130308 4:55:39 InnoDB: Completed initialization of buffer pool 130308 4:55:39 InnoDB: highest supported file format is Barracuda.

  - by O.Shevchenko

  I am running SCEP client to enroll certificates on NDES server. If OpenSSL is not in FIPS mode - everything works fine. In FIPS mode i get the following error: pkcs7_unwrap():pkcs7.c:708] error decrypting inner PKCS#7 139968442623728:error:060A60A3:digital envelope routines:FIPS_CIPHERINIT:disabled for fips:fips_enc.c:142: 139968442623728:error:21072077:PKCS7 routines:PKCS7_decrypt:decrypt error:pk7_smime.c:557: That's because NDES server uses DES algorithm to encrypt returned PKCS#7 packet. I used the following debug code: /* Copy enveloped data from PKCS#7 */ bytes = BIO_read(pkcs7bio, buffer, sizeof(buffer)); BIO_write(outbio, buffer, bytes); p7enc = d2i_PKCS7_bio(outbio, NULL); /* Get encryption PKCS#7 algorithm */ enc_alg=p7enc->d.enveloped->enc_data->algorithm; evp_cipher=EVP_get_cipherbyobj(enc_alg->algorithm); printf("evp_cipher->nid = %d\n", evp_cipher->nid); The last string always prints: evp_cipher-nid = 31 defined in openssl-1.0.1c/include/openssl/objects.h #define SN_des_cbc "DES-CBC" #define LN_des_cbc "des-cbc" #define NID_des_cbc 31 I use 3DES algorithm for PKCS7 requests encryption in my code (pscep.enc_alg = (EVP_CIPHER *)EVP_des_ede3_cbc()) and NDES server accepts these requests, but it always returns answer encrypted with DES. Can I configure Wndows NDES server to use Triple DES (3DES) algorithm for PKCS#7 answer encryption?

• emacs, writing custom commands which use term-mode

  - by valya

  Hello, I'm using Emacs and M-x term for a terminal. Since my typical workflow looks like this: edit some code C-x C-o to the terminal buffer (or C-x b term[Enter] or something) press Up key to use the last command press Enter to run it C-x C-o to go back I want to bind all of these (except the first step... maybe) to one command, I believe Emacs is awesome enough to do that :-) So, a command must: go to the buffer with terminal (maybe it shouldn't change any windows at all, maybe it should split the window vertially (if it weren't split already) and use the right sid) run a last command what've been run there go back to the last buffer/part of the screen Thank you! I'm not really used to the Emacs scripting system, and I hope someone will help me and someone else will be able to use the answer to improve his workflow, since I believe this is a pretty common one Examples of commands: python manage.py test python manage.py test stats python solve.py # for project-euler puzzles :-) the first and the second runs over a ssh (in a terminal) sometimes (I like developing with vagrant) I understand that it's easy to bind the first and the third ones, but the second changes too often - I'd just like to "run last command"

• Which is more secure: Tomcat standalone or Tomcat behind Apache?

  - by NoozNooz42

  This question is not about performance, nor about load-balancing, etc. Which would be more secure: running Tomcat in standalone mode or running Tomcat behind apache? The thing is, Tomcat is written in Java and hence it is pretty much immune to buffer overrun/overflow (unless a buffer overrun in a C-written lib used by Tomcat can be triggered, but they're rare [the last I remember was in zlib, many many moons ago] and one heck of a hack to actually exploit), which gets rid of a lot of potential exploits. This page: http://wiki.apache.org/tomcat/FAQ/Security has this to say: There have been no public cases of damage done to a company, organization, or individual due to a Tomcat security issue... there have been only theoretical vulnerabilities found. All of those were addressed even though there were no documented cases of actual exploitation of these vulnerabilities. This, combined with the fact that buffer overrun/overflow are pretty much non-existent in Java, makes me believe that Tomcat in standalone mode is pretty secure. In addition to that, I can install both Java and Tomcat on Linux without needing to be root. The only moment I need to be root is to set up a transparent port 8080 to port 80 forwarding (and 8443 to 443). Two iptables line as root, that's all root is needed for. (I don't know for Apache). Apache is much more used than Tomcat and definitely does not have a security track record as good as Tomcat. What would make Tomcat + Apache more secure? What would make Tomcat + Apache less secure? In short: which is more secure, Tomcat standalone or Tomcat with Apache? (remembering that performance aren't an issue here)
