• Can't install Apache 2.2.22 on Ubuntu 13.10

  - by B18C1

  My work environment requires Apache 2.2.22 instead of the latest version of 2.4. My machine is currently running Ubuntu 13.10. When I use Synaptic or apt-get it will not allow me to choose an older version of Apache than 2.4. So my question is, how can I force an install of Apache 2.2.22 on Ubuntu 13.10 using Synaptic or apt-get. When I do try to specify the version I get the following: sudo apt-get install apache2=2.2.22-1ubuntu1 [sudo] password for b18c1: Reading package lists...

• Excel (.xls) files not opening in Excel when launched from Explorer

  - by Alex Berry

  I appear to have done something to Excel (2003) whereby whenever I double-click on an Excel file (.xls) in Windows Explorer, Excel launches OK, but the corresponding workbook doesn't open, and I'm left with an instance of Excel with no active workbook, i.e. a grey screen. It was fine earlier on, but now it's goosed. It's clearly not windows file associations, as Excel launches ok. It's a problem specific to Excel itself... Any thoughts what I might have done to give rise to this? Many thanks, Alex.

• Can't the NetworkManager applet to appear in the Gnome panel in Ubuntu

  - by Nate

  I have researched this problem extensively and I can't seem to find an answer. In Ubuntu 10.04 LTS, I want to connect to my VPN through the NetworkManager applet. I installed all the network manager packages, including the gnome client. I understand I need to add the "Notification Area" to the panel, which I have done. I checked that the NetworkManager is running: nate@nate-desktop:~$ service network-manager status network-manager start/running, process 763 In /etc/NetworkManager/nm-system-settings.conf, I have added managed=true (don't know if this matters, but I saw it suggested on one forum): nate@nate-desktop:~$ more /etc/NetworkManager/nm-system-settings.conf # This file is installed into /etc/NetworkManager, and is loaded by # NetworkManager by default. To override, specify: '--config file' # during NM startup. This can be done by appending to DAEMON_OPTS in # the file: # # /etc/default/NetworkManager # [main] plugins=ifupdown,keyfile [ifupdown] #managed=false managed=true At this point, it looks like NetworkManager is running but it's not appearing in the NotificationArea of the panel. I don't know what else to try. Any ideas?

• Penalty for collision during a racing game

  - by Arthur Wulf White

  In a racing game: How should we penalize the player for colliding head on into obstacles such as walls, trees and so on. What is the way it is done in your favorite racing game? How is it done in other successful racing games? Do you think temporarily disabling the engine for a second is too severe? If I do go that route, how would I convey the 'engine is disabled' to the player in a subtle and easily understood way? Is this 'too much' of a penalty? Would the slow-down from the collision be sufficient to discourage the player from driving too carelessly? Which one is more fun? Should I consider a health-bar and affect engine performance for 'low health' status? Could you offer examples of games that handle this well and one that do it poorly? Please share your experience with racing games obstacles and reference games you feel perform well in this aspect. I am sure we all enjoy our racing games differently and I would like to hear different opinions regarding this issue. I would also like to hear how you feel we should penalize or reward for colliding with other vehicles? Should enemy vehicles be destroyable? Should they slow down severely when they hit the back of your car or would that make the gameplay imbalanced?

• Facebook like button for a Facebook feed item

  - by jverdeyen

  Here is what I do: When the admin of a website i'm creating adds a new 'news' item to his website, it directly posts the same item on the Facebook 'fanpage' of the website. This is done by an Facebook app with the permissions to post an item on the Facebook fanpage. So far so good. I'm getting the new post id from the facebook graph. Here is what I want to achieve: I'm adding a 'like' button on the original website, but when this is clicked it should be referenced to the same post item on the facebook page. So if someone likes the news post on the website he should also like the referencing facebook feed post. Which is exactly the same. Can this be done? I've been playing around with the href etc of the like button, without any success. When I hit the like button it likes the url given, but is doesn't recognizes that this is a feed post. Any idea? Thx in advance.

• Add a Real-Time Earth Wallpaper App to Ubuntu with xplanetFX

  - by Asian Angel

  Are you tired of the same old wallpaper on your Ubuntu desktop? Now you can go from blah to literally spacious, real-time styled views of Earth with the xplanetFX Wallpaper App for Linux. You can conveniently access the “file type” downloads, screenshots, and jump-to links all on the front page. For our example we downloaded the .deb setup file on our system. The setup file will need to download three additional files to complete the setup process. After those are downloaded all dependencies will have been met and you can complete the installation process. Once that is done you can find xplanetFX by going to the Accessories Section of your Ubuntu Menu. This is what the main control window looks like when you start xplanetFX for the first time. You should take a few moments to look through the various tabs and tweak the settings for items like location, screen resolution, timing, auto-start, etc. When you are done click on Execute and within a few moments your desktop will have a fresh new look! Note: It took ~30 seconds for the display to activate on our system. Have fun with xplanetFX! xplanetFX Homepage [via OMG!

• Blending animations for more character movements

  - by Noob Saibot

  I am making a hack n slash 3rd person game. And I want the character movements to be more dynamic not like fighting games where you have a moves list. I want to animate tons of different animations and have them "Tween" between each other? Because I want the controls to not be keyboard mouse. I want it to be all keyboard. that way you have up to 10 inputs (All your fingers) to blend and morph animations to create more fluid movements. In the end this will almost be similar to characters typing a phrase or string of keys rather than move forward mouse look click to melee. My question is. Has anyone done this before and would someone go about trying to tween lets say one for key on the keyboard excluding Tab, Caps, R+Shift, L+Shift, Enter, R+Ctrl, L+Ctrl, L+Alt, R+Alt, Windows Key, and Menu. So thats all the numbers, letters and punctuation keys. Thats 46 keys gives me a combination of 46P1 = 5502622159812088949850305428800254892961651752960000000000L (used Python) and with a minimum entry value of 2 keypresses shortening to half. This is not humanly possible to create so many inique animations in one lifetime. But I'm guessing there is a reason this hasn't been done already. Or if I just used 10 basic keys. Maybe ASDF SPACE (RIGHT HAND) 456+0 (LEFT HAND KEYPAD) it would give me 3,628,800 posible unique animations.

• ignore ipv6 router advertisements for static addresses with bonded interfaces

  - by boran

  I need to attribute static IPv6 addresses (not use autoconfigured addresses, and ignore router advertisements). This can be done as follows for a standard interface like eth0 iface eth0 inet6 static address myprefix:mysubnet::myip gateway myprefix:mysubnet::mygatewayip netmask 64 pre-up /sbin/sysctl -q -w net.ipv6.conf.$IFACE.autoconf=0 pre-up /sbin/sysctl -q -w net.ipv6.conf.$IFACE.accept_ra=0 However, how can this be done for bonded interfaces? using the "all" interface does not work. Systems is Ubuntu 10.04, 2.6.24-24-server. If one uses the above sysctl command for the bond0, the networking hangs on boot, because /proc/sys/net/ipv6/conf/bond0 does not yet exist and cannot be written to. One the system has booted /proc/sys/net/ipv6/conf/bond0 exist, so one solution after booting is to add the following to /etc/rc.local: /sbin/sysctl -q -w net.ipv6.conf.bond0.autoconf=0 /sbin/sysctl -q -w net.ipv6.conf.bond0.accept_ra=0 /etc/init.d/networking restart and this has the desired effect, the autoconfig v6 address disappears. Seems like a bit of a hack though, are there better solutions?

• How should Code Review be Carried Out?

  - by Graviton

  My previous question has to do with how to advance code review among the developers. Here I am interested in how the code review session should be carried out, so that both the reviewer and reviewed are feeling comfortable about it. I have done some code review before, but the experience sucks big time. My previous manager would come to us-- on an ad hoc basis-- and tell us to explain our code to him. Since he wasn't very familiar with the code base, I spent a huge amount of times explaining just the most basic structure of my code to him. This took a long time and by the time we were done, we were both exhausted. Then he would raise issues with my code. Most issues he raised were cosmetic in nature ( e.g, don't use region for this code block, change the variable name from xxx to yyy even though the later makes even less sense, and so on). We did this a few rounds, and the review session didn't derive much benefits for us, and we stopped. What do you have to do, in order to make code review a natural, enjoyable, thought stimulating, bug-fixing and mutual-learning experience?

• How to refactor while keeping accuracy and redundancy?

  - by jluzwick

  Before I ask this question I will preface it with our environment. My team consists of 3 programmers working on multiple different projects. Due to this, our use of testing is mostly limited to very general black box testing. Take the following assumptions also: Unit Tests will eventually be written but I'm under strict orders to refactor first Ignore common Test-Driven Development techniques when given this environment, my time is limited. I understand that if this were done correctly, our team would actually save money in the long-term by building Unit-Tests before hand. I'm about to refactor a fairly large portion of the code that is critical. While I believe my code will accurately work when done and after our black box testing, I realize that there will be new data that the new code might not be able to handle. What I wanted to know is how to keep old code that functions 98% of the time so that we can call those subroutines in case the new code doesn't work properly. Right now I'm thinking of separating the old code in a separate class file and adding a variable to our config that will tell the program which code to use. Is there a better way to handle this? NOTE: We do use revision control and we have archived builds so the client could always revert to a previous build, but I would like to see if there is a decent way of doing this besides reverting. I want this so they can use the other new functionality delivered in the new build. Edit: While I agree I will need to write Unit Tests for this, I don't believe I will capture everything with them. I'm looking for ways to easily be able to revert to the old, functional code should anything happen. While I know this is a poor practice, I'm planning on removing this code after our team can guarantee that the new code works to the same standards as the old.

• Render on other render targets starting from one already rendered on

  - by JTulip

  I have to perform a double pass convolution on a texture that is actually the color attachment of another render target, and store it in the color attachment of ANOTHER render target. This must be done multiple time, but using the same texture as starting point What I do now is (a bit abstracted, but what I have abstract is guaranteed to work singularly) renderOnRT(firstTarget); // This is working. for each other RT currRT{ glBindFramebuffer(GL_FRAMEBUFFER, currRT.frameBufferID); programX.use(); glActiveTexture(GL_TEXTURE0); glBindTexture(GL_TEXTURE_2D, firstTarget.colorAttachmentID); programX.setUniform1i("colourTexture",0); glActiveTexture(GL_TEXTURE1); glBindTexture(GL_TEXTURE_2D, firstTarget.depthAttachmentID); programX.setUniform1i("depthTexture",1); glBindBuffer(GL_ARRAY_BUFFER, quadBuffID); // quadBuffID is a VBO for a screen aligned quad. It is fine. programX.vertexAttribPointer(POSITION_ATTRIBUTE, 3, GL_FLOAT, GL_FALSE, 0, (void*)0); glDrawArrays(GL_QUADS,0,4); programY.use(); glActiveTexture(GL_TEXTURE0); glBindTexture(GL_TEXTURE_2D, currRT.colorAttachmentID); // The second pass is done on the previous pass programY.setUniform1i("colourTexture",0); glActiveTexture(GL_TEXTURE1); glBindTexture(GL_TEXTURE_2D, currRT.depthAttachmentID); programY.setUniform1i("depthTexture",1); glBindBuffer(GL_ARRAY_BUFFER, quadBuffID); programY.vertexAttribPointer(POSITION_ATTRIBUTE, 3, GL_FLOAT, GL_FALSE, 0, (void*)0); glDrawArrays(GL_QUADS, 0, 4); } The problem is that I end up with black textures and not the wanted result. The GLSL programs program(X,Y) works fine, already tested on single targets. Is there something stupid I am missing? Even an hint is much appreciated, thanks!

• Apache HTTPS ProxyPass certificate location

  - by oz1cz

  I'm trying to set up an Apache server that uses ProxyPass to pass HTTPS requests on to another server. Let's call the proxy server ALPHA and the target server BETA. ALPHA does not run HTTPS, but BETA does. I first tried using this virtual host specification on ALPHA: <VirtualHost *:443> ServerName mysite.com ProxyPass / https://192.168.1.105/ # BETA's IP address ProxyPassReverse / https://192.168.1.105/ # BETA's IP address ProxyPreserveHost On ProxyTimeout 600 SSLProxyEngine On RequestHeader set Front-End-Https "On" CacheDisable * </VirtualHost> But when I tried this, Apache complained saying, "[error] Server should be SSL-aware but has no certificate configured [Hint: SSLCertificateFile]". I had to copy the SSL certificate from BETA to ALPHA and add these lines to the host specification on ALPHA: SSLEngine on SSLCertificateKeyFile /usr/local/ssl/private/BETA_private.key SSLCertificateFile /usr/local/ssl/crt/BETA_public.crt SSLCertificateChainFile /usr/local/ssl/crt/BETA_intermediate.crt Now the system works. But I have a feeling that I have done something wrong or unnecessary. I have the web site's private key and certificate lying on both ALPHA and BETA. Is that necessary? Should I have done it differently?

• NFS or GFS for LVS 10 Server Setup

  - by Michael Robinson

  Currently we have a 10 servers LVS hosting setup. The people we hired to set it up did not anything about GFS which was our preferred Central Storage File System Solution. As we have tight time constraint, we just told them to use whatever they were familiar with which is NFS. I have since done some research and it seems that NFS is not ideal for the type of high traffic site we are hoping to build. I couldn't find much info online about the signaficance differences between the 2. As we to setup all servers again right now, should we stick with NFS or find someone who knows how to setup GFS amd go with that. We need a setup that is highly reliable and scalable as we intend. As after initial setup is done, we expect high increases in traffic and load.

• Is shipping a Clojure desktop app realistic?

  - by Cedric Martin

  I'm currently shipping a desktop Java application. It is a plain old Java 5 Java / Swing app and so far everything worked nicely. Java 5 was targetted because some users were on OS X version / computers that shall never have Java 6 (we may lift this limitation soon and switch to a newer Java and simply abandoning my users stuck with Java 5). I'm quickly getting up to speed with Clojure but I haven't really done lots of Clojure-to-Java and Java-to-Clojure yet and I was wondering if it was realistic to ship a Clojure desktop application instead of a Java application? The application I'm shipping is currently about 12 MB with all the .jar so adding Clojure doesn't seen to be too much of an issue. My plan would be to have Clojure call Java APIs: my application is already divided in several independent jars. If I understand correctly calling Clojure from Java is harder than calling Java code from Clojure which is why I'd basically rewrite all the UI (part of the UI, mixing Swing components and self-made BufferedImages needs to be rewritten anyway due to the rise of retina display), and do all the 'wiring' from Clojure. So that's the problem I'm facing: is it realistic to ship a Clojure desktop app? (it certainly doesn't seem to be very widespread but then shipping plain Java desktop apps ain't that common either and I'm doing it anyway) Technically, what would need to be done? (compared to shipping a Java app)

• Error with APE Server Installation

  - by sadmicrowave

  I was trying to install APE-Server from the .deb file at the ape-server homepage (www.ape-project.org) and I ran into an error so wanted to try removing the installation and reinstalling. I did a sudo apt-get remove ape-server which ran successfully but left ape-server folders in my /etc/ and /etc/init.d locations. Me being an idiot new comer to linux decided that manually delete those folders. Now when I reinstall the ape-server those folders don't get recreated and therefore I cannot send the /etc/init.d/ape-server [option] command because the folder is not found. When I try to sudo apt-get purge (or remove) ape-server I get the following sudo apt-get purge ape-server Reading package lists... Done Building dependency tree Reading state information...

• What naughty ways are there of driving traffic?

  - by Tom Wright

  OK, so this is purely for my intellectual curiosity and I'm not interested in illegal methods (no botnets please). But say, for instance, that some organisation incentivised link sharing in a bid to drive publicity. How could I drive traffic to my link? Obviously I could spam all my friends on social networking sites, which is what they want me to do, but that doesn't sound as fun as trying to game the system. (Not that I necessarily dispute the merit of this particular campaign.) The ideas I've come up with so far (in order of increasing deviousness) include: Link-dropping - This is too close to what they want me to do to be devious, but I've done it here (sorry) and I've done it on Twitter. I'm subverting it slightly by focusing on the game aspects rather than their desired message. AdWords - Not very devious at all, but effectively free with the vouchers I've accrued. That said, I must be pretty poor at choosing keywords, because I've seen very few hits (~5) so far. Browser testing websites - The target has a robots txt which prevents browsershots from processing it, but I got around this by including it in an iframe on a page that I hosted. But my creative juices have run dry I'm afraid. Does anyone have any cheeky/devious/cunning/all-of-the-above idea for driving traffic to my page?

• Can't add NetworkManager applet to gnome panel

  - by Nate

  I have researched this problem extensively and I can't seem to find an answer. In Ubuntu 10.04 LTS, I want to connect to my VPN through the NetworkManager applet. I installed all the network manager packages, including the gnome client. I understand I need to add the "Notification Area" to the panel, which I have done. I checked that the NetworkManager is running: nate@nate-desktop:~$ service network-manager status network-manager start/running, process 763 In /etc/NetworkManager/nm-system-settings.conf, I have added managed=true (don't know if this matters, but I saw it suggested on one forum): nate@nate-desktop:~$ more /etc/NetworkManager/nm-system-settings.conf # This file is installed into /etc/NetworkManager, and is loaded by # NetworkManager by default. To override, specify: '--config file' # during NM startup. This can be done by appending to DAEMON_OPTS in # the file: # # /etc/default/NetworkManager # [main] plugins=ifupdown,keyfile [ifupdown] #managed=false managed=true I restarted NetworkManager and tried rebooting, too. At this point, it looks like NetworkManager is running but it's not appearing in the NotificationArea of the panel. I don't know what else to try. Any ideas?

• The spork/platypus average: shameless self promotion

  - by Roger Hart

  This is the video of presentation I gave at UA Europe and TCUK this year. The actual sub-title was "Content strategy at Red Gate Software", but this heading feels more honest. For anybody who missed it, or is just vaguely interested, here's a link to me talking about de-suckifying the web. You can find the slideshare deck here, too* Watching it back is more than a little embarrassing, and makes me really, really want to do a follow up, so I can do three things: explain the rest of the big web project, now we've done it give some data on the outcome of the content review make a grovelling apology to our marketing guys, who I've been unfairly mean to in a childish effort to look cool There are a whole bunch of other TCUK presentations online, too. You can find them all here: http://tiny.cc/tcuk10_videos I'd particularly recommend Chris Atherton's: "Everything you always wanted to know about psychology and technical communication" - it's full of cool stuff. You should probably also watch David Black's opening keynote, which managed to make my hour of precocious grandstanding look measured, meek, and helpful. He actually makes some interesting points, but you'd basically have to ship Richard Dawkins off to Utah, if you wanted to go further out of your way to aggravate your audience. It does give an engaging account of running a large tech comms project, and raise some questions about how we propose to understand a world where increasing amounts of our stuff gets done by increasingly many increasingly complicated tissues of APIs. Well, sort of. That's what all the notes I made were about, anyway.   *Slideshare ate my fonts. Just so we're clear on this: I'd never use badly-kerned Arial in a presentation. Don't worry.
