• Is it possible to upgrade PHP to 5.3 on a Centos Kloxo installation?

  - by Malachi Soord

  I have a VPS running Centos with Kloxo on and I was wondering how I would upgrade the PHP to 5.3 - It's currently running 5.2.6. When I try and do a yum update I get the following errors: Resolving Dependencies --> Running transaction check --> Processing Dependency: libpq.so.4 for package: lxphp ---> Package postgresql-libs.i386 0:8.3.7-umask.7 set to be updated --> Finished Dependency Resolution lxphp-5.2.1-400.i386 from installed has depsolving problems --> Missing Dependency: libpq.so.4 is needed by package lxphp-5.2.1-400.i386 (installed) Error: Missing Dependency: libpq.so.4 is needed by package lxphp-5.2.1-400.i386 (installed) You could try using --skip-broken to work around the problem You could try running: package-cleanup --problems package-cleanup --dupes rpm -Va --nofiles --nodigest The program package-cleanup is found in the yum-utils package. Any help would be greatly appreciated.

• Preserve the state of the start screen

  - by axrwkr

  What would I need to do in order to cause the start screen to stay the way it was the last time I saw it when I go back to it? I've noticed that every time I leave the start screen it resets back to the beginning, this means that I need to scroll back to where I was to get the same view. I don't want to change the order of the applications on the start screen to accommodate this, I would much prefer it if I could find a way to make the start screen stay the way it was so I can move on from there and also if there was a way to jump to the beginning or the end of the list that would be great. I imagine I can just use the search feature to find a specific program, but that's just an extra step, almost as bad as having to scroll.

• How to write to a file and, while the file is still being writen, read and parse its contents using

  - by Isabelle

  Hello. I'm actually trying to write a shell script that logs the output of a command to a file but, since the command takes a long time to complete (about 15 minutes), I would like to start parsing the output of the command (content of the file) before the command is completed, so I can send messages to the standard output (the user), like: 10% complete 45% complete and so on. Program steps Redirect command to a file: $(command) $FILE Start reading and parsing the output ($FILE) before the command is finished. I thought of using pararell programming, but I havent't got the hang of it. Any help you be appreciated. Best regards.

• How can I add metadata to NTFS files/folders?

  - by Pwdr

  I want to tag different file types (i.e. .pdf, .epub, .iso, .bin, folders,..) using the same descriptive fields. For example i would like a metadata field "type" which would be "eBook" on pdf- and epub-files, "CD-Image" on iso- and bin-files. I read about Alternate Data Streams (ADS) to make this possible. Does anyone know a good program for Windows 7 to tag different files and search for them? It is important for me, that the metadata is NOT stored in a separate database. I move the files a lot and need to stay flexible (ADSs 'stick' to the files). Any ideas?

• How can I programmatically renumber pages in a PDF?

  - by Andrew

  As a graduate student, I come across PDFs of articles and book chapters on a daily basis. Sometimes these PDFs are paginated correctly internally (that is, if an article starts on page 67, the PDF starts on page 67 as well; not on page 1). When they aren't, I have to open the file in Acrobat and renumber the pages in the "Page Thumbnails" panel. I would love to be able to automate this whole process with a script (bash, Python, AppleScript, whatever) that lets me pass the first actual page number... something like fixpagination example.pdf 67. However, I cannot find any terminal-based program that can re-paginate PDFs. Neither pdftk nor PyPDF seem to be able to deal with pagination. Are there any scriptable programs that can internally re-paginate PDF files?

• Interested in scp recipe for sftp [closed]

  - by GJZ

  You wrote in a reply this Blockquote The problem is that sftp runs as the user's id -- first, the sftp client ssh's into the target host as the given user, then runs sftp-server. Since sftp-server is running as a regular user, it has no way to "give away" a file (change owner of a file). However, if you are able to use scp, and assign a key pair to each user, you can get around this. This involves adding a user's key to root's ~/.ssh/authorized_keys file, with a "command=" parameter to force it to run a script that sanitizes and alters the arguments of the server-side scp program. I've used this technique before to set up an anonymous scp dropbox that allowed anyone to submit a file, and ensure that no one could retrieve submitted files and also prevent overwrites. If you are open to this technique, let me know and I'll update this post with a quick recipe. We are interested in this scp quick recipe for our community services file sharing. Best Regards, Gert Jan Zeilstra

• Can't Open Up Event Viewer

  - by Erik W

  I just installed a large backlog of Windows Updates (I have Windows 7 Ultimate 64-bit) and now a handful of programs are acting strangely (not opening, crashing, etc) I went to try to diagnose the program using the Event Viewer, but when I open it up I get the error "Microsoft Management Console has Stopped Working" immediately after I double-click on the icon. Is there any way for me to figure out what is going wrong? I have another Windows 7 PC, that I tried to remotely view the logs from, but I got the error "The RPC Server is Unavailable". I'd like to start up the service, but oh wait, I can't open anything in the "Administrative Tools". I'd like not to re-install Windows, as I had just done so a couple months ago after a Windows Update jacked up my graphics card drivers.

• Rendering multiple squares fast?

  - by Sam

  so I'm doing my first steps with openGL development on android and I'm kinda stuck at some serious performance issues... What I'm trying to do is render a whole grid of single colored squares on to the screen and I'm getting framerates of ~7FPS. The squares are 9px in size right now with one pixel border in between, so I get a few thousand of them. I have a class "Square" and the Renderer iterates over all Squares every frame and calls the draw() method of each (just the iteration is fast enough, with no openGL code the whole thing runs smootlhy at 60FPS). Right now the draw() method looks like this: // Prepare the square coordinate data GLES20.glVertexAttribPointer(mPositionHandle, COORDS_PER_VERTEX, GLES20.GL_FLOAT, false, vertexStride, vertexBuffer); // Set color for drawing the square GLES20.glUniform4fv(mColorHandle, 1, color, 0); // Draw the square GLES20.glDrawElements(GLES20.GL_TRIANGLES, drawOrder.length, GLES20.GL_UNSIGNED_SHORT, drawListBuffer); So its actually only 3 openGL calls. Everything else (loading shaders, filling buffers, getting appropriate handles, etc.) is done in the Constructor and things like the Program and the handles are also static attributes. What am I missing here, why is it rendering so slow? I've also tried loading the buffer data into VBOs, but this is actually slower... Maybe I did something wrong though. Any help greatly appreciated! :)

• 12.10 Wireless networking

  - by user108594

  I downloaded ubuntu 12.10 using WUBI and cannot connect to the internet. I removed it and downloaded ubuntu 12.04 still cannot connect. This I assume rules out the program being the problem. I reinstalled 12.10. When loaded I get the same message W/red (x) stating Internet not connected. I went to the Settings drop down box and it does not reveal the network list but (enable networking has a ck mark). Am running a HP Laptop with a w/7/64 OS that has a kill switch that indicates (orangeno connection) I downloaded 12.10 on my desktop (on the same network) and everything OK. I tried to follow the instructions in the help menu but got lost and confused . Sincerely Dan Additional Info per request Broadcom 802.11b/g Wlan Internal pc [hp laptop] P.S. I've been out of town for about a month. TKS for your gitback I did install 12.10 via cd and everything ok,but retried alongside 7 and unable to connect to internet,also took laptop and hard wired using ethernet cable and everything ok. stumped again and running out of ideas!!!

• Is the Entity Component System architecture object oriented by definition?

  - by tieTYT

  Is the Entity Component System architecture object oriented, by definition? It seems more procedural or functional to me. My opinion is that it doesn't prevent you from implementing it in an OO language, but it would not be idiomatic to do so in a staunchly OO way. It seems like ECS separates data (E & C) from behavior (S). As evidence: The idea is to have no game methods embedded in the entity. And: The component consists of a minimal set of data needed for a specific purpose Systems are single purpose functions that take a set of entities which have a specific component I think this is not object oriented because a big part of being object oriented is combining your data and behavior together. As evidence: In contrast, the object-oriented approach encourages the programmer to place data where it is not directly accessible by the rest of the program. Instead, the data is accessed by calling specially written functions, commonly called methods, which are bundled in with the data. ECS, on the other hand, seems to be all about separating your data from your behavior.

• Windows: Is there something to see and remotely control single(!) windows on a remote PC?

  - by Horst Walter

  Is there something where I can see and control single(!) windows of PC1 on PC2 remotely. Basically like it is possible with X-Windows. I am not talking / asking about A software which displays the whole desktop remotely (like VNC, Windows RDP). A X-windows server for windows, to connect to Linux. The answer here ( Windows Remote Desktop Connection for just a single window (or a single program) ) requires Windows Server 2008. I need to run this on two Windows 7 machines. Example: PC1 shows three windows, and I transfer, see, and control window 2 on PC2. -- Edit -- I have checked whether there is an X-Server for Windows <- Windows. But there seems not to be one other than Unix <- Windows: http://stackoverflow.com/questions/40453/what-is-a-good-and-free-x-server-for-windows

• 7 drived classes with one common base class

  - by user144905

  i have written the following code, //main.cpp #include<iostream> #include<string> #include"human.h" #include"computer.h" #include"referee.h" #include"RandomComputer.h" #include"Avalanche.h" #include"Bureaucrat.h" #include"Toolbox.h" #include"Crescendo.h" #include"PaperDoll.h" #include"FistfullODollors.h" using namespace std; int main() { Avalanche pla1; Avalanche pla2; referee f; pla1.disp(); for (int i=0;i<5;i++) { cout<<pla2.mov[i]; } return 0; } in this program all included classes except referee.h and human.h are drived from computer.h. each drived calls has a char array variable which is initialized when a member of a drived class is declared. the problem is that when i declare tow diffrent drived class memebers lets say Avalache and ToolBox. upon printing the char array for one of them using for loop it prints nothing. However if i declare only one of them in main.cpp the it works properly. and the file for computer.h is as such: #ifndef COMPUTER_H #define COMPUTER_H class computer { public: int nump; char mov[]; void disp(); }; #endif ToolBox.h is like this: #ifndef TOOLBOX_H #define TOOLBOX_H #include"computer.h" class Toolbox: public computer { public: Toolbox(); }; #endif finally Avalanche.h is as following: #ifndef AVALANCHE_H #define AVALANCHE_H #include"computer.h" class Avalanche: public computer { public: Avalanche(); }; #endif

• Where did the notion of "one return only" come from?

  - by FredOverflow

  I often talk to Java programmers who say "Don't put multiple return statements in the same method." When I ask them to tell me the reasons why, all I get is "The coding standard says so." or "It's confusing." When they show me solutions with a single return statement, the code looks uglier to me. For example: if (blablabla) return 42; else return 97; "This is ugly, you have to use a local variable!" int result; if (blablabla) result = 42; else result = 97; return result; How does this 50% code bloat make the program any easier to understand? Personally, I find it harder, because the state space has just increased by another variable that could easily have been prevented. Of course, normally I would just write: return (blablabla) ? 42 : 97; But the conditional operator gets even less love among Java programmers. "It's incomprehensible!" Where did this notion of "one return only" come from, and why do people adhere to it rigidly?

• Java desktop programmer starting to learn Android development: how different is it?

  - by Prog

  I'm a Java programmer. All of my experience is on desktop applications, using Swing for the GUI. I spend a lot of time studying OOP, I have decent understanding of OO concepts and I design and program by the OO approach. I'm thinking of starting to learn Android development soon, and I'm wondering how different it is from desktop development. Obviously the GUI libraries will be different (not Swing), but other than that, I want to know if there are significant differences. I will divide this question to two parts: Apart from the GUI libraries, am I still going to use the standard Java libarary I'm used to? Aka same data structues, same utility classes, etc.? If not, what are the main differences between the libraries I'm used to and the libraries I'll be using? How different is Android development in regard to OO design? Are all of the familiar principles, design patterns, techniques and best pratices just as valid and used? Or is OOP and OOD in Android development significantly different than OO in desktop development? To summarize: apart from GUI design, how different is Java Android development than Java desktop development?

• eCryptfs on ubuntu server : How to keep the home mounted without being over ssh?

  - by Bebeoix

  I have a daemon program who need to read in a file who is saved somewhere in my home folder. But every time I close my ssh connection, this daemon can't read the file because it appear that eCryptfs unmount the home. Maybe there is an option to force eCryptfs to not only mount with an ssh connection ? I didn't found it. Thanks. PS : I know this thread, http://askubuntu.com/questions/165608/why-is-ecryptfs-only-mounting-private-home-directory-over-ssh, but this is not the proper/good way to deal with the request.

• Windows 7 - You don't have permissions to save in this folder

  - by James

  Huh? I'm getting this message - "You don't have permissions to save in this folder" - even though I am the only user on this machine, and administrator. How can I set permissions for myself to do everything, everywhere (including saving deleting etc)? Thanks. Edit: Sorry, forgot to say which folder it was. It is a folder in Program Files, where I save my PHP files for local testing. Sorry if Im a bit daft with all this, but I've upgraded straight from XP to 7, and having never used vista, I'm used to being allowed to have full control.

• ssh freezes when trying to connect to some hosts

  - by NS Gopikrishnan

  When I try to ssh to particular machine/s in a list, The SSH command happens to be freezing. I tried out setting ssh timeout. But then also it's freezes even after the timeout. In verbose mode : OpenSSH_3.9p1, OpenSSL 0.9.7a Feb 19 2003 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug1: Connecting to x358.x.server.com [10.x.x.x] port 22. debug1: fd 3 clearing O_NONBLOCK debug1: Connection established. debug1: identity file /export/home/sqlrpt/.ssh/identity type -1 debug1: identity file /export/home/sqlrpt/.ssh/id_rsa type -1 debug1: identity file /export/home/sqlrpt/.ssh/id_dsa type 2 At this point it freezes. A work around I thought was to create a child process for each ssh calls and if the process doesn't respond after a timeout - Kill it. But are there any less complex ways, so that I can accommodate it in a shell script itself rather than going for a C/C++ program ?

• How to reformat reStructuredText?

  - by wal-o-mat

  I'm writing reST in vim, which handles line breaks for me (after 80 chars). However, since I frequently go back and edit the text before, lines get ugly again. For example, in tables, it's sometimes annoying to re-format a complete table just because you need a line break in some place. So I wish I had a program that reads my ugly-but-correct reStructuredText and outputs it nicely formatted and wrapped. I found that pandoc in.rst -w rst mostly works, but it has some drawbacks. For example :author: John Doe becomes author John Doe and title formatting is changed as well. Sadly, there seems to be no rst2rst or something similar. Does anyone have some advice?

• Cannot get Virtual PC to install on my machine

  - by Brandon

  I'm not sure what I'm doing wrong. I ran the tool to check that hardware virtualization is enabled, and it is (i7-2600). I ran the proper version of the Virtual PC download (Windows 7 Professional x64) and I can see the Windows Virtual PC (KB958559) update in my installed updates list. The .msu file runs fine without errors, but even after multiple reboots I can't actually find a trace of Virtual PC anywhere. There is nothing in program files, the start menu, or system32. Am I missing a step?

• Finding a job: feedback on my current prodicument and my relentless efforts [closed]

  - by Michael

  I am a very well rounded IT guy, with a passion for programming in particular. I have been through a BS program less the internship as I refuse to go lower than minimum wage (i.e. free) and/or such opportunities find the institution lacking. Since then, the catalog for my degree has changed, so I am making peace without it. I go up for job interviews and get myself no farther than a submitted resume. I have even changed my strategy and made this website: http://goo.gl/qqpN8 to showcase my highlights (but not at all exhaustive) for specific areas in the US and paid for classified ads. The 'internship' is notable as I am just trying to get my foot in the door. Because IT is so vast, with programming and engineering in particular, I spend my time researching the requirements for the job I am applying for. This has made me that well rounded guy I spoke of earlier, but has made me a victim of being a jack-of-all-trades; unfortunately being a master of none. I embrace my gung-ho attitude and find it to be a trait that has powered my career before. But I am starting to lose steam. I want it straight. What is not appealing about everything I am doing? What are the technologies that I need to focus on that are in great demand at the moment?

• Access console of QNX server

  - by dhergert

  I am new to QNX (although I am familiar with Unix/Linux). This company I am working with has an old QNX (4.25) server in a server room that they remotely access via Windows terminals (Kermit via Telnet) which presents them with a text-based program. I need to get into/onto the actual box to be able to view directories, files, etc... and wondering if I can do that "remotely", along the lines of how I would SSH into a Unix box. Is there something like that in QNX? Do I need to actually hook up a keyboard/monitor to this server to be presented with a console? Would I even get a console?

• Looking for internet traffic manager software for Windows 7

  - by Semyon Perepelitsa

  I have 128 KB/s (1 Mbit/s) internet connection. Not quite fast for downloading big files, but it is okay for internet browsing. When I start big file dowload, I cannot surf the web normally: pages appears slowly, especially pictures there. Therefore I pause downloading, but I'm regularly spending much time on reading articles or leaving the computer alone, when I can allow the file being dowloaded. Is there any software that can automize the process of pausing and resuming download or simply automatically regulate internet speed for each application using Internet? I download files using different software and protocols (Download Master for http, ftp; uTorrent for torrents; many other programs for updating themselves), so I don't want to be tied to particular program for downloading.

• Blatant copyright theft

  - by Tom Gullen

  Found a user on the forum trying to solicit business for his website, a good user reported it and I checked the website out. Firstly and most dangerously it's attempting to sell our original software, which is open source. Our open source software is around 15mb big and he's serving a 50mb download and trying to sell it for $20. He's also stolen our CSS/images/site design in general which is all custom built. I attempted to open reasonable discussion with him, and he responded promptly saying he would remove offending materials if he could just have 3 days to sort it out which I accepted. I'm not sure what his plan was because everything on that site is offending material. Anyway he messaged back saying the site was offline, and it was, but it went back online shortly afterwards. It's pretty sickening that someone is selling open source work as their own, (the site about us page references him as the sole developer etc etc, it's unbelievable to read it). I want to shut it down, what are my options? I'm going to contact his domain registrar, web host, and Paypal (that's how he's selling the program). Any other ideas?

• Changing wallpaper depending on time of day via script or batch file?

  - by Patrick

  I want to have 2 different wallpapers that change according to time of day (6 and 22 hours respectively) and only want to display the night one after 22 hours and the day one only after 6 hours and until 22 hours. I didn't find a program that can do this after a standby, so I thought it should be easy to realize with the task scheduler running a script. Now the question is not only how to realize such a script, but also if the script should include the time checking or the task scheduler. I'm not sure what would work better with long times of the PC being in standby. I tried a few scripts already from similar questions and hoped I could modify to them to my needs, but they didn't work at all. Anyone able to help me? TIA.
