  • Should HTTP Verbs Be Used Semantically?

    - by Xophmeister
    If I'm making a web application which integrates with a server-side backend, would it be considered best practice to use HTTP methods semantically? That is, for example, if I'm fetching data (e.g., to populate a menu, etc.), I would use GET, but to update data (e.g., save a record), I would use POST. (I realise there are other methods that may be even more appropriate, but we need to consider browser support.) I can see the benefits of this in the sense that it's effectively a RESTful API, but at a slightly increased development cost. In my previous projects, I've POST'd everything: Is it worth switching to a RESTful mindset simply for the sake of best practice?

  • Can't install AMD drivers and Blinking problem

    - by demonscream
    I just installed Ubuntu 12.04 LTS with WUBI, everything is going fine and ubuntu is awesome but i have a little problem. When i open my Sony VAIO model E laptop, i have 2 choices (which is normal) but when i select Ubuntu 1/2 of the time it will just give a rapidly blinkin color background and can only be corrected if i reboot the computer and select ubuntu again. I think this has something to do with the fact i can't get any driver update for my computer from AMD, according to their website, VAIO computers aren't supported. I have a AMD RADEON HD 7650M graphic card which is not detected in ubuntu. When i try to install the drivers using the drivers application it gives a "can't install" error. What should i do?

  • Is not being paid for training normal?

    - by user23838
    I'm a recent college graduate, and I recently had a interview with a company for an entry-level programming job. The company told me that they require two months of unpaid training for all entry level programmers. The reason given was that since they are providing free training, there wouldn't be any compensation. Is this normal? Update For others junior developers looking at this: Don't go for these type of scams. This was my first interview. I interview with 10 other companies around the area and got about 9 job offers from them. I worked for a fortune 50 company for 9 months with good pay and recently found a better opportunity for even better pay and better work. I guess moral is to be patient and have confidence in yourself.

  • XNA content.load Dependancy

    - by Richard
    Quick question, My project i'm building for test purposes is working fine but i have dependencies flying around everywhere due to the XNA framework. In Update i have gametime passed everywhere... this is okay. In Draw i have gametime & spritebatch passed everywhere... this is okay. My issue is in the content.load textures/sounds/fonts. I have them as public variables ie Texture1 = Content.load(of texture2d)("Texture1") I'm passing a 'Game1' pointer into the constructor of every new class being instantiated to gain access to these variables. Am i missing an OOP trick to prevent me having to pass a pointer to 'game1' to every New class?

  • How to build a dynamic grub on a usb-drive?

    - by 13east
    I would like to setup GRUB on a USB where it detects automatically the available OS installations on the machine that it is plugged into. This could be useful if you messed up your default GRUB menu on a computer and would like to boot into the machine w/out booting Live-OS. Or if you have multiple Live-OS installations on a USB-Drive and would like to add/remove different installations w/out needing to update grub manually. I know that Grub2 has a OS-prober feature that looks for other installations on the hard-drive, but will that work in either of the scenarios listed above?

  • Examples of Android Joystick Controls? [on hold]

    - by KRB
    I can't seem to find any well executed code examples for Android joystick controls. Whatever it may be, algorithms, pseudo code, actual code examples, strategies, or anything to assist with the design and implementation of Android joystick controls; I can't seem to find anything decent on the net. What are some well executed examples? More specifically, Pseudo Code Current Examples Idea/Design Functionality Description Controller Hints Related Directly to Android Architecture What kind of classes will I have making this? Will there be only one? How would this be implemented to the game architecture? All things I am thinking about. Cheers! UPDATE I've found this on the subject Joystick Example1, though I am still looking for different examples/resources. Answered my own question with a link to the code of the above video. It's a fantastic start to Android Joystick Controls.

  • Reset Windows share password after 'Remember forever'

    - by timmit
    I've been happily connecting to a Windows share from my 14.04 machine. When I first entered the password for the share I chose to have it remembered forever. Yesterday I changed the password on the Windows machine, today I can't access the share... My searches for a solution have been in vain, most suggestions say that there is an entry in the Password & Keys (seahorse) app that should be deleted, this doesn't exist for me. I even ran seahorse as the root user to see if the key was hidden away in there, but no luck. Is there anywhere else I should be looking? Shouldn't the Nautilus app be prompting me to update my password in this scenario?

  • Line6 UX1 soundcard and Ubuntu

    - by the_drow
    I own a Line6 UX1 soundcard and I would like to make it work for Ubuntu. I have followed the instructions here and it worked. But at some point I upgraded my kernel version (not sure what uname -a prints but it's related) and it stopped working. Here's what uname -a prints: Linux ubuntu 2.6.32-29-generic 58-Ubuntu SMP Fri Feb 11 20:52:10 UTC 2011 x86_64 GNU/Linux I figured out that maybe it's installed per version so I used svn update and hit make again. My guess was right as it copied the relevant files to the new version's folder. I restarted and still nothing. Should I revert to an older version? Or is there a solution here?

  • Why circles are not created if small?

    - by Suzan Cioc
    I have changed the scale to my own and now I cant create any object, including circle, if it is of the size which is normal for my scale. I am to create big object first and then modify it to smaller size. Looks like minimal size protection is set somewhere. Where? UPDATE While creating a circle, if I drag for 0.04m circle disappears after drag end. If I drag for 0.08m circle also disappears. If I drag for more than 0.1m, circle persists after drag end. How to set so that it persist after 0.01m too?

  • Battery icon constantly empty when discharging Vaio VGN-FZ210CE

    - by Alex
    I have a Sony Vaio VGN-210CE laptop, and its battery does not report the drain rate properly. In 11.10 and earlier, the battery icon would update with the percentage, not the estimated time. In 12.04 and 12.10, it estimates by time, which is always some very low value because the estimated drain rate is 700W. I currently have 89% in my battery but the icon is red and empty. If there is an application I should install, or a setting I should change, please let me know. Thanks!

  • What is a normalized Vector?

    - by draiden
    Can someone explain the following code? I need to learn what each part means so I can turn it into enemy movement in a space shoot-em-up Vec2d playerPos; Vec2d direction; // always normalized float velocity; I get the above is naming two 2d Vector objects, and creating a variable called velocity. I'm not sure what the normalized comment is about, though. update() { direction = normalize(playerPos - enemyPos); playerPos = playerPos + direction * velocity; }

  • Dual-boot question involving separate HD and windows 8

    - by user286976
    I use an external HD with Ubuntu+GRUB on it. This allows me to effectively "hijack" most systems. Basically it's a permanent LiveUSB - my own system wherever I go. I use it for recovery mainly when Windows systems muck up, and for portability (as I can have my system on the go, without effecting the pc I'm borrowing, much like a LiveCD). I'm about to update to Windows 8 now [on a new, different computer]. Is there any special measure I should take to do this? I've seen a similar post here, but the OP had both harddrives plugged in simultaneously - that's not exactly my setup. Thank you :) EDIT: added for clarification that this is for a totally new computer.

  • Grub-Customizer made Windows 7 disappear from Gurb2

    - by user199055
    I am running dual-boot Ubuntu 12.04/Windows7. I wanted to change the boot order in Grub2 to have Windows on top of the list. I installed Grub-Customizer on Ubuntu 12.04 using the following terminal commands copied from another post: sudo add-apt-repository ppa:adabbas/1stppa sudo apt-get update sudo apt-get install grub-customizer After installing, I launched Grub-Customizer from Dash Home. Windows 7 does not appear in the list. I closed the program and was prompted to save the current settings. Upon rebooting, Windows did not appear in the Grub2 list. I went back into Grub-Customizer and clicked the "Revert" button but still no Windows 7. Does anyone know how I can fix this?

  • Listening For and Raising Events in the BLL

    - by OneSource
    I'm working on a WinForms .Net Recording App and I have a RecordingMgr in my BLL to listen for new events captured by another class. I want to display the events in my UI and I'm stuck as to what's the best way to do this. I can think of a few scenarios to handle this but all of them seem sub-optimal: Listen for and handle Recorded Events in both the UI and in the RecordingMgr After receiving the event in the RecordingMgr, raise it again so that the UI can pick it up Create a variable in RecordingMgr (e.g., a BindingList) that the UI can bind to and update it when an Event is received Ditch the RecordingMgr and just put the event recording logic in the UI What's the best approach? Something above or something else?

  • Should I understand SVN before I jump to GIT?

    - by John Isaacks
    I work in a department where no one has ever used source control before, including myself. I am trying to push the concept. I have spent a little while researching SVN. I some basics learned. I can Create/update/checkout/commit with command line and from Tortoise. I am starting to learn how to tag and branch but still confused a lot about conflicts between branches and trunk etc. I am still learning, but I do not have a physical person who can show me anything. Its all from books/tutorials and trial and error. From what I have read online it seems like git is the better thing to know, but its also more complicated. I don't want to overwhelm myself. Should I continue to master svn before moving to git or would I be wiser to just jump to git now? Are there pros and cons to both approaches?

  • How to keep specific old kernel on my next kernel upgrade?

    - by tvrtko
    I just updated my Ubuntu 14.04 and got a new kernel. This new kernel is not working properly for me so I booted the previous version. Let's call this good old working version "3.13.0-24.47". Now, I want to keep this "3.13.0-24.47" version until I decide to delete it manually. I want to be able to upgrade my kernel each time there is a new version in hope of getting the one which works again. Until then, I want to use the "3.13.0-24.47". I'm afraid that next update will delete my "3.13.0-24.47" version because there are only two kernel versions available at a given time on my system (/boot).

  • What is the SEO-recommended method for using underscores and dashes in URLs that contain geographic locations?

    - by ElHaix
    In reading through this article: In Subfolder & File Names, Use Dashes, Not Underscores Good: Good: http://www.domain.com/sub-folder/file-name.htm Bad: http://www.domain.com/sub_folder/file_name.htm In my URL's, I may have one or two city names, ending with the province/state: Burnaby_New_Westminister-BC/[some search term]. My URL rules currently are defined such that everything after the dash is the prov/state. Some geographic locations already contain dashes: Notre-Dame-de-Grâce (in QC), which I would convert to ~/Notre_Dame_de_Grace-QC/ I thought of placing the prov/state after another "/", however in some cases the province/state name may not exist, thus ~/Notre_Dame_de_Grace/, so the first term after the domain name contains the geo location {city, city_name-state}. I am now revisiting this, and wondering if this rule set should change, and if so, what is the recommended way of implementing this? -- UPDATE -- After reviewing this video, I see that I should be using the dashes, rather than underscores. However since I still want to have my geo locations in the first URL section, is there anything wrong with using a double-dash separator - ie: /city-name--state/ ?

  • Need to run `nvidia-xconfig` before booting

    - by RobinJ
    I formatted my whole hard drive, and installed Elementary OS (Ubuntu 10.10) on it in an attempt to get rid of all the problems. It failed. Every since I installed the nvidia-current drivers I first need to boot into recovery mode, and run sudo nvidia-xconfig before booting the system in the normal way. If I don't do this, it will just stop at a black screen after the boot screen, responding to nothing but CTRL+ALT+DELETE and the power button. When I boot the system after running the nvidia-xconfig command I can just start working as usual. Update I suspect it's got something to do with Plymouth. I shall have to try it again before I can confirm it, but removing the quiet and splash parameters from the kernel line in /boot/grub/grub.cfg seems to help. But still, I like my Plymouth screen. A black screen with text rolling over it (or without the text) doesn't attract me much.

  • IIS and content caching

    - by JayC
    I'm a web developer and administer of a Windows 2008R2 Could Instance with IIS 7. I recently made an update to our website, but when I revisited the website, the website was being viewed with old stylings. I did a refresh (shift + reload button in Firefox) and of course the website displayed as it should. I didn't worry about it, until my client had the same issue in Safari. So, my question, in general, is, how do I prevent this from happening again, and yet still afford some caching of our site? I noticed we did not have content expiration set up on our webserver sites, so I've set that up, but did I really need to? I've also looked at Etags, and, honestly, it's hard for me to know whether or not I should use them or not. One comment I read somewhere there isn't really any issue with Etags scenarios in IIS (even in webfarms)... but, I dunno. Anybody have any suggestions, links, info? Thanks.

  • Flash Retirement - HTML to be "the one"

    - by RichMill
    I will update this blog post as we get closer to the retirement of the Flash portal. As you might have read the support.oracle.com  flash site will be replaced with what you see in supporthtml.oracle.com,  once we get the rest of the features and functions ported over to the html site. The HTML site is written using Oracle's ADF stack. So we are now pretty much 100% eating our own dog food.  More details to follow.

  • How to make a minimal upgrade?

    - by wajed
    I use apt-get install --no-install-recommends ubuntu-desktop to install minimal desktop. I want to upgrade my system to the latest version (12.04) with it still being minimal. How do I do that? What I tried:- I tried Update Manager, and it gave me the Option to upgrade to 11.10 first, then to 12.04. What happened after I upgraded to 11.10 is that my desktop got bloated, and instead of the system using 500MB of RAM, now it uses about 1.5GB I can't even start apps anymore.

  • changed plesk root name, what DNS settings get modified?

    - by NRGdallas
    we recently changed our plesk server's main URL from siteold.com to sitenew.com. many websites had their NS set to ns1.siteold.com - does plesk automatically update that to need ns1.sitenew.com? should I change the godaddy settings? attempting to change them states "Nameserver Not Registered" - is this simply the delay required? lastly, when adding a new domain to plesk, one would simply need to adjust the nameserver for that site in godaddy to ns1.sitenew.com or ns1.newdomain.com? (does plesk have a centralized name server, or does each site acquire its own?)
