• Problem with missing JSON functions on PHP 5.2.6 / Plesk 8.4

  - by Drachenviech

  I have a vserver running openSuse 10.3, Apache 2 and Plesk 8.4. I can update/upgrade neither, as it is apparently not recommended to upgrade openSuse 10.3 (and an update to the EOL 10.4 does not seem to make much sense) and Plesk fails to update no matter what version I try (even fails to upgrade to 8.4.1). Still I can live with that somehow, primarily because I don’t have the time to do a fresh remote install on the vserver. What really is a problem is, that though the installed PHP is 5.2.6 it has no zip library and no json functions. The first is probably because PHP was not compiled with --enable-zip. The second is a big mystery though. As I understand it, it always comes with PHP unless its compiled with the --disable-json configure option. This is however not the case. And the json extension module is just not there. I even tried to enable it with extension=json.so with no luck either. the configure options of my PHP are (as shipped with Plesk 8.4) '../configure' '--prefix=/usr' '--datadir=/usr/share/php5' '--mandir=/usr/share/man' '--bindir=/usr/bin' '--with-libdir=lib' '--includedir=/usr/include' '--sysconfdir=/etc/php5/apache2' '--with-config-file-path=/etc/php5/apache2' '--with-config-file-scan-dir=/etc/php5/conf.d' '--enable-libxml' '--enable-session' '--with-mm' '--with-pcre-regex=/usr' '--enable-xml' '--enable-simplexml' '--enable-spl' '--enable-filter' '--disable-debug' '--enable-inline-optimization' '--disable-rpath' '--disable-static' '--enable-shared' '--program-suffix=5' '--with-pic' '--with-gnu-ld' '--with-system-tzdata=/usr/share/zoneinfo' '--with-apxs2=/usr/sbin/apxs2' '--disable-all' '--disable-cli' As I understand it, PECL is not an option with 5.2.6. Or am I mistaken? Even if I was not, the openSuse repository only goes as far as PHP 5.2.4. The openSuse install even came without zypper, which I had to manually install. So is there a way to get ziplib and json running in PHP 5.2.6 without having to recompile the binary?

• Problems with No-IP redirecting

  - by user171156

  I am setting up a webserver on my ubuntu desktop 13.04, everything is working fine except; When trying to access the server through the external host using no-ip, it gives the original index created by apache on setup. While when I try to connect to the server via my real IP address from externally, it goes to the correct index. I have been trying to figure out what the issue is on this problem as nothing is working because of that bad redirect, I'm wondering if anyone of you could help me out, or advise me in the right path. Thank you very much! PS; If more info needed I'll provide, but this should explain it all.

• How to fix Ubuntu 12.04.3 boot to black screen full of errors in white text, after upgrading on dell inspiron 1501

  - by Ibuntu

  I am running a Dell Inspiron 1501 I use Linux only. No Microsoft or Apple operating systems (or really anything closed-source). I've only been using Linux for a little over a year but I'm starting to gain a comfortable level of familiarity with the system and terminology. I've been having some issues with Quantel Quetzal and Raring Ringtail, especially with older hardware, so I opted to install Ubuntu 12.04.3 Precise Pangolin on the Inspiron 1501. I checked my MD5 sum after downloading my ISO and all was good. I have in fact used this iso/dvd to install Precise Pangolin successfully on a few other systems (some of which are even older than this laptop). Install goes fine. The wireless card doesn't work out of the box but this is a known issue which is fairly easy to fix. So, first thing I did was open up a terminal and run sudo apt-get update && sudo apt-get upgrade which, part way through, crashed (I assume lightdm and possibly X) and took me to a black screen filled with white lines of text that were either errors or just the ouputs of commands. The reason I say that is because I was unable to gleam any useful information from the output on the screen. I did take a picture however and will post a link. After that, every time I boot the system it goes right to that black screen posting all the error messages or output in white text. I never get a purple Ubuntu splash, so from what I can tell after reading this wiki article: https://wiki.ubuntu.com/X/Troubleshooting/BlankScreen That means that after the kernel is selected, it is unable to correctly implement the settings it needs. If the purple splash never shows, the frame buffer was never set correctly right? This leads me to believe that it could be a kernel issue? The wiki suggested to try and pinpoint the issue by rolling back kernels until I find one that works. Is this my best option? I think I'm going to give it a try anyways and will let everyone know if I am able to solve the issue this way. I have since done a few reinstalls and some trouble-shooting including a couple hours scouring the net for anyone with any kind of similar issue. Most of the issues I could find involved getting a black screen after login and none of them said anything about any information output on this black screen. My reinstalls have taught me that there is no issue updating, but as soon as I run sudo apt-get upgrade my system goes to the black screen and every time I boot it up it does the same thing. The only way to fix is by reinstall. I never get any ability to log in. After a hard power off to the laptop (because I cannot use ctrl+alt+del to reboot) when it boots again it goes to the grub boot menu and I can select between regular boot, recovery mode and the two memtest options. I never tried the memtest options but the other two both lead to the same black screen. Some people having a black/blank screen issue claim to have fixed it by using 12.10 or 13.04 but I believe they were having a different issue where they got a black/blank screen after logging in. I think I will still give these images a try, but mostly figured I would just wait another day or two for 13.10. Other things I figured I would try from the following three articles: After logging in, there's a black screen and my cursor, nothing else! in Ubuntu 12.10 Black Screen on Login After Upgrading to 12.04 I can't get to the login screen include opening a terminal using ctrl+alt+f1 and trying a variety of reseting unity, x settings, lightdm (or switching to gdm); but I doubt this will work or that I will even be able to access a terminal. I'm pretty sure the whole system is stuck after it loads the last line on the black screen. I will try these things and post more information when I have. Hopefully someone has an idea in the meantime and I will keep checking back trying to find a solution. Thank you. Here are 3 different pictures of the error message. I had to take with my phone: http://ubuntuone.com/album/0TBBkxmVajJIQQtoN9mVdN

• Updating windows xp hard drive controller from ubuntu live disk

  - by Joel

  The problem: When booting, I get a blue screen shortly after the Windows XP logo splash screen. The error code is 7b, and the second hex number is 0xC0000034. Based on this link (item 7) it appears the driver should be updated. Oddly, I made no changes to the drivers recently. I suspect it was something in a windows update or the newest upgrade of my antivirus (eset). But I digress. The BSOD makes me unable to boot into Windows at all, so I can't update the driver from there. I've run various bios-level diagnostics (including full surface scan) and the hd looks good. I'm also able to boot to an old ubuntu disk and read files from the hd. The question: Based on the above, it appears that I need to update the Windows hard drive controller from the ubuntu live disk. How do I do that?

• In PHP, what are the different design patterns to implement OO controllers as opposed to procedural controllers?

  - by Ryan

  For example, it's very straightforward to have an index.php controller be a procedural script like so: <?php //include classes and functions //get some data from the database //and/or process a form submission //render HTML using your template system ?> Then I can just navigate to http://mysite.com/index.php and the above procedural script is essentially acting as a simple controller. Here the controller mechanism is a basic procedural script. How then do you make controllers classes instead of procedural scripts? Must the controller class always be tied to the routing mechanism?

• Updating Mcafee Group Shield on Exchange Server

  - by AllanPedersen

  So I don't actually have a problem yet, but I might. You see my fathers company have 10 computers and an exchange server with Mcafee Group Shield. lately they've had issues with mails from customers being blocked. I found both the problem and the solution: Mcafee update so basicly update their Mcafee group shield to the newest service pack and we are all back in buisness.. while I have some limited exchange experience and AD too. I don't have any Mcafee experience. I don't wanna crash their server for a week and have them need to get someone to recover it. So my question in here.. is it supposedly as easy as to click an 'update' button and to reboot your server.. or are there several issues I need to be aware about..? Maybe there is some common issue that goes with updating antivirus on an exchange server that I don't know about..

• Mercurial changeset hook problem when auto updating. Server permissions maybe??

  - by Gary Willoughby

  I am using Mercurial SCM over a LAN using a normal shared folder instead of http and i'm having a problem getting the auto update hook to run. I have entered this hook as detailed here: http://mercurial.selenic.com/wiki/FAQ#FAQ.2BAC8-CommonProblems.Any_way_to_.27hg_push.27_and_have_an_automatic_.27hg_update.27_on_the_remote_server.3F This installs the hook, but when i push something to the remote repo i get an error: added 1 changesets with 1 changes to 1 files running hook changegroup: hg update >&2 warning: changegroup hook exited with status -1 There is a stackoverflow question similar to this here: http://stackoverflow.com/questions/2885246/mercurial-auto-update-problem but it offers no solutions other than it may be a permissions error somewhere. Has anyone else had this problem and can anyone else shed any more light on this or give me a heads up on where to start fixing this? Thanks.

• How to handle the different frame rate on different devices?

  - by Fenwick

  I am not quite sure how frame per second works on a web page. I have a Canvas game that involves in moving an image from point A to B, and measuring the time elapsed. The code can be as simple as: var timeStamp = Date.now(); function update(){ obj.y += obj.speed; text = "Time: "+ (Date.now() - timeStamp) + "ms"; } The function update() is called every frame. The problem is that the time elapsed is different from device to device. It is pretty short on my PC, but get longer on my iPad, and is much longer on my cell phone. I thought it is because the FPS is smaller on mobile devices, so instead of calling update() every frame, I call it every 1ms by using a setInterval. But this does not solve the problem. In my understanding, the function for setInterval is invoked based on the increment in system time, other than frame rate, so it should fix the problem. Am I missing anything here? If the setInterval function is called based on FPS, is there any way to get around with the FPS difference across devices? On a side note, I have sort of a "water simulator" on the same canvas. It involves in redrawing about 60 objects which can be 600x600 pixels for every frame, so it could be a frame rate killer. I am using Phaser.js but not really using much of its functionalities, if that helps.

• Highlighting new rows in ADF Table

  - by Sireesha Pinninti

  About This article explains how to hightlight newly inserted rows in an ADF Table without writing any extra java/javascript code.IntroductionSometimes we may wish to give more clarification to the end user by differentiating between newly inserted rows and the existing rows(i.e the rows from DB) in a table by highlighting new rows in different color as in the figure shown below. SolutionWe can achieve the same by giving following EL to inlineStyle property of every column inside af:table: #{row.row.entities[0].entityState == 0?'background-color:#307D7E;':''}ExplanationHere is the explanation for row.row.entities[0].entityState given inside EL which returns the state of the row(i.e, New, Modified, Unmodified, Initialized etc.)row - Refers to a tree node binding(instance of FacesCtrlHierNodeBinding) at runtimerow.row - Refers to an instance of row that the tree node is based onrow.row.entities[0] - Gets the Entity row at zeroth index. In most of the cases, the table will be based on single entity. If your table is based on multiple entities then the index needs to be given accordingly.row.row.entities[0].entityState - Gets Entity Object's current Entity-state in the transaction.(0 - New, Modified - 2, Unmodified - 1, Initialized - -1,  etc.,)

• The clock problem - to if or not to if?

  - by trejder

  Let's say, we have a simple digital clock. To "power" it, we use a routine executed every second. We update seconds part in it. But, what about minutes and hours part? What is better / more professional / offers better performance: Ignore all checking and update hour, minute and seconds part each time, every second. Use if + a variable for checking, if 60 (or 3600) seconds passed and update minute / hour part only at that precise moments. This leads us to a question, what is better -- unnecessary drawings (first approach) or extra ifs? I've just spotted a Javascript digital clock, one of millions similar on one of billions pages. And I noticed that all three parts (hours, minutes and seconds) are updated every second, though first changes its value only once per 3600 seconds and second once per 60 seconds. I'm not to experienced developer, so I might me wrong. But everything, what I've learnt up until now, tells me, that if are far better then executing drawing / refreshing sequences only to draw the same content.

• Kill .so file process

  - by demonofnight

  I have a program, I cannot change the code. It calls some .so file's function, but don't delete the object in the end. When the owner of the program tries to update the program he kills it and send the update, but the .so file is in use so he can't update the file. It's on an AIX platform. Is it possible to force to kill the .so file? If I do a fuser -f on the file it returns nothing. Can I create another program to kill the program, is there any command to do that?

• Faster 2D Collision detection

  - by eShredder

  Recently I've been working on a fast-paced 2d shooter and I came across a mighty problem. Collision detection. Sure, it is working, but it is very slow. My goal is: Have lots of enemies on screen and have them to not touch each other. All of the enemies are chasing the player entity. Most of them have the same speed so sooner or later they all end up taking the same space while chasing the player. This really drops the fun factor since, for the player, it looks like you are being chased by one enemy only. To prevent them to take the same space I added a collision detection (a very basic 2D detection, the only method I know of) which is. Enemy class update method Loop through all enemies (continue; if the loop points at this object) If enemy object intersects with this object Push enemy object away from this enemy object This works fine. As long as I only have <200 enemy entities that is. When I get closer to 300-350 enemy entities my frame rate begins to drop heavily. First I thought it was bad rendering so I removed their draw call. This did not help at all so of course I realised it was the update method. The only heavy part in their update method is this each-enemy-loops-through-every-enemy part. When I get closer to 300 enemies the game does a 90000 (300x300) step itteration. My my~ I'm sure there must be another way to aproach this collision detection. Though I have no idea how. The pages I find is about how to actually do the collision between two objects or how to check collision between an object and a tile. I already know those two things. tl;dr? How do I aproach collision detection between LOTS of entities? Quick edit: If it is to any help, I'm using C# XNA.

• how to architect this to make it unit testable

  - by SOfanatic

  I'm currently working on a project where I'm receiving an object via web service (WSDL). The overall process is the following: Receive object - add/delete/update parts (or all) of it - and return the object with the changes made. The thing is that sometimes these changes are complicated and there is some logic involved, other databases, other web services, etc. so to facilitate this I'm creating a custom object that mimics the original one but has some enhanced functionality to make some things easier. So I'm trying to have this process: Receive original object - convert/copy it to custom object - add/delete/update - convert/copy it back to original object - return original object. Example: public class Row { public List<Field> Fields { get; set; } public string RowId { get; set; } public Row() { this.Fields = new List<Field>(); } } public class Field { public string Number { get; set; } public string Value { get; set; } } So for example, one of the "actions" to perform on this would be to find all Fields in a Row that match a Value equal to something, and update them with some other value. I have a CustomRow class that represents the Row class, how can I make this class unit testable? Do I have to create an interface ICustomRow to mock it in the unit test? If one of the actions is to sum all of the Values in the Fields that have a Number equal to 10, like this function, how can design the custom class to facilitate unit tests. Sample function: public int Sum(FieldNumber number) { return row.Fields.Where(x => x.FieldNumber.Equals(number)).Sum(x => x.FieldValue); } Am I approaching this the wrong way?

• How to Enable Priority Inbox on Android (and Setup Important-Only Notifications)

  - by The Geek

  Yesterday Google released an updated Gmail application for Android 2.2 phones that supports the Priority Inbox feature—and more importantly, allows you to change your notifications to only alert you for important email. Let’s take a look. Note: If you’ve never used Priority Inbox, you should really give it a try—it rearranges your email into what is and isn’t important, and you can customize how it classifies messages easily. The idea is that it learns over time, so if you send a lot of emails back and forth with somebody, it will know that they are probably important—you can manually adjust the settings as well. To update the Gmail application, you’ll want to head into the Market and access Menu –> Downloads, where you should see Gmail in the list, and it should let you update from there. If you don’t see an update, you’re either not running Android 2.2, or it has already updated automatically Latest Features How-To Geek ETC The 50 Best Registry Hacks that Make Windows Better The How-To Geek Holiday Gift Guide (Geeky Stuff We Like) LCD?

• My Sites Were Hacked. What To Do?

  - by Vad

  I host multiple domains with this very popular hosting provider and I just went into one of my sites and... I see a black page with message "Hacked by...". I checked and all my sites with the provider are showing this same page. Inside of file system I have seen the hacker placed all default.* and index.* files with this message. So the hacker overwrote all index pages, placed new pages and that is under every, I say again, every folder. Cleaning this up will be close to a most horrible job. What to do (right now I am awaiting the restore of files from hosting provider)? How to prevent this? Whom to blame?

• A simple example of movement prediction

  - by Daniel

  I've seen lots of examples of theory about the reason for client-side prediction, but I'm having a hard time converting it into code. I was wondering if someone knows of some specific examples that share some of the code, or can share their knowledge to shed some light into my situation. I'm trying to run some tests to get a the movement going (smoothly) between multiple clients. I'm using mouse input to initiate movement. I'm using AS3 and C# on a local Player.IO server. Right now I'm trying to get the Client side working, as I'm only forwarding position info with the client. I have 2 timers, one is an onEnterFrame and the other is a 100ms Timer, and one on mouseClick listener. When I click anywhere with a mouse, I update my player class to give it a destination point On every enterFrame Event for the player, it moves towards the destination point At every 100ms it sends a message to the server with the position of where it should be in a 100ms. The distance traveled is calculated by taking the distance (in Pixels) that the player can travel in one second, and dividing it by the framerate for the onEnterFrame handler, and by the update frequency (1/0.100s) for the server update. For the other Players, the location is interpolated and animated on every frame based on the new location. Is this the right way of doing it?

• Errors in ~/.xsession-errors

• I can't get grub menu to show up during boot

  - by wim

  After trying (and failing) to install better ATI drivers in 11.10, I've somehow lost my grub menu at boot time. The screen does change to the familiar purple colour, but instead of a list of boot options it's just blank solid colour, and then disappears quickly and boots into the default entry normally. How can I get the bootloader back? I've tried sudo update-grub and also various different combinations of resolutions and colour depths in startupmanager application with no success (640x480, 1024x768, 1600x1200, 16 bits, 8 bits, 10 second delay, 7 second delay, 2 second delay...) edit: I have already tried holding down Shift during bootup and it does not seem to change the behaviour. I get the message "GRUB Loading" in the terminal, but then the place where the grub menu normally appears I get a solid blank magenta screen for a while. Here are the contents of /etc/default/grub # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: # info -f grub -n 'Simple configuration' GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX=" vga=798 splash" # Uncomment to enable BadRAM filtering, modify to suit your needs # This works with Linux (no patch required) and with any kernel that obtains # the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...) #GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef" # Uncomment to disable graphical terminal (grub-pc only) #GRUB_TERMINAL=console # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo' #GRUB_GFXMODE=640x480 # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux #GRUB_DISABLE_LINUX_UUID=true # Uncomment to disable generation of recovery mode menu entries #GRUB_DISABLE_RECOVERY="true" # Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1"

• Uses of LINK tag

  - by DisgruntledGoat

  The <link> tag appears to have many uses aside from stylesheets. For example the W3 suggest using it for previous/next/index pages. I know that Opera also has a Navigation toolbar that will show links when present, including Home, Index, Contents, Previous, Next, Copyright, Author and more. (I doubt it is actually used by more than a handful of people.) Are there any other attributes that are useful, or other uses for the ones above? What about SEO benefit?

• Powershell and DfsrConfigurationFromAD - how to check all servers are updated?

  - by user57792

  I have two Win2012R2 servers (SERVER1 and SERVER2) that uses DFS Replication for keeping a couple of folders synchronized. Using the following Powershell-script that i run on SERVER1 I disconnect it from the group: Set-DfsrConnection -GroupName "Group1" -SourceComputerName "SERVER1" -DestinationComputerName "SERVER2" -DisableConnection $True; And to update both the servers with the configuration I run the command: Update-DfsrConfigurationFromAD -ComputerName "SERVER1","SERVER2" Now the question is, how can check on SERVER1 that SERVER2 has gotten the updated information from the AD so that I can be sure that the connection has been disabled? Usually it takes around 10-30 seconds after the Update-DfsrConfigurationFromAD command has been run before the DFS Management on SERVER2 gets updated but I need some kind of a "check and sleep loop" in my code. I've tried checking event logs and using Invoke-Command {Get-DfsrConnection} from PM-SERVER01 but nothing seems to work.

• How to Organize Subdirectories? [closed]

  - by Gary Iverson

  I am working on my first major (several hundred pages) website design and development project. I want to create subdirectories for each of the website's categories, which in turn have their own subdirectories for easy user navigation. Example: website.com/directory. I am aware that by placing an index.html file within each directory, the browser automatically detects and navigates to that page, but that seems like a messy solution (having multiple index.html files, albeit in distinct folders), and I cannot imagine everyone does that. So my question is...how do you properly organize and use subdirectories?

  This question is, I suppose, not limited to Javascript, but it is the language I use to create my game, so I'll use it as an example. For now, I have structured my HTML5 game like this: var fps = 60; var game = new Game(); setInterval(game.update, 1000/fps); And game.update looks like this: this.update = function() { this.parseInput(); this.logic(); this.physics(); this.draw(); } This seems a bit inefficient, maybe I don't need to do all of those things at once. An obvious alternative would be to have more intervals performing individual tasks, but is it worth it? var fps = 60; var game = new Game(); setInterval(game.draw, 1000/fps); setInterval(game.physics, 1000/a); //where "a" is some constant, performing the same function as "fps" ... With which approach should I go and why? Is there a better alternative? Also, in case the second approach is the best, how frequently should I perform the tasks?

• C redevient le langage le plus utilisé devant Java et C++, d'après le classement des langages de pro

  Le C redevient le langage de programmation le plus utilisé Devant Java et le C++, d'après TIOBE Software TIOBE Software publie chaque mois son classement (le TIOBE Programming Community index) des langages de programmation. D'après cet index, pour la première fois depuis 4 ans, Java perd sa place de langage le plus populaire au profit du C qui retrouve donc le top du classement. Le C "est assez constant au fil des années, il varie entre 15% et 20% de parts de marché depuis presque 10 ans. Donc, la raison principale de cette place de numéro 1 n'est pas une progression du C, mais plutôt la baisse de son concurrent Java", explique l'analyse qui accompagne ce ...
