  • Learning to program in the modern era?

    - by BBHorus
    At this time, lets say in the modern era, in which order do you organize a programing course for teaching and/or learning, what should be learned first, what should emphasize: Databases Data structures Design patterns Programing paradigms(Procedural, functional, OOP, ...etc ) Operating System Some specific programing language What about English if you are not native speaker or doesn't know English AI Anything else... I ask this because in the university that I went, the programing course was awful it was not focus on what you were going to see out when you work what you were supposed to learn. PS: Again sorry about my English is not my main language. ...Experts and gurus please share

  • Are there any reliable solutions for annotations/reflection/code-metadata in C?

    - by dukeofgaming
    Not all languages support java-like annotations or C#-like attributes or code metadata in general, however that doesn't mean it is not possible to have in languages that don't have this. An example is PHP with Stubbles and the Doctrine annotation library. My question is, is there anything like this for C?, or are there any reliable ways of doing reflection with extended code metadata in C? Ideally, I'm looking for something that reads javadoc-like comments. Edit: The reason for me *needing* as opposed to just wanting, is that I need to generate C code and code-metadata from a database, as well as being able to edit that metadada and update the database. The volume of the work (~15,000 variables/structures/functions to generate from this database) justifies the solution.

  • No background/wallpaper in Ubuntu 12.04 - what to do?

    - by magnesus
    This is how my desktop looks like after moving Firefox window arround: The background just doesn't redraw, there is no wallpaper. It is like that since update to 12.04 - it was the same in 11.10 but I had special intel drivers then that fixed this problem. Doesn't seem to be fixed in 12.04 even with the ppa I was using then. What can I do? I couldn't find anything about it on Google because results were unrelated. :( I have Samsung RF-511 notebook with Nvidia card turned off - so it's using only Intel from i7.

  • PC won't boot up after installing 11.10

    - by bakhshu
    I have a HP/Compaq s1010z (AMD64) desktop and installed 11.10 from a CD (using the entire disk). So it formatted the entire drive, went through installation and then it ejected the CD and asked me to click the Restart button, which I did. It rebooted fine the first time, but any time thereafter, it fails. Meaning, after the initial BIOS screen, the monitor seems to be stuck in limbo with a text cursor blinking on the top left corner, as if it can't find anything to boot from. At first I tried reinstalling (reformat entire drive again) - no improvement. Then I did an in-place re-installation (leave home dirs in place, just redo the OS), nothing there either. Then I put in the 11.04 CD, changed the boot order to CD first, and got the CD menu, chose 'Boot from first hard disk' and it booted fine. The problem is that I can't boot without the 11.04 CD, how ironic! Any ideas?

  • Social Media JSR 357 NOT approved by Executive Committee

    - by alexismp
    JSR 357 (Social Media API) has not passed the initial ballot which means, according to the JCP rules, that "the JSR submitter(s) who may revise the JSR and resubmit it within 14 days". Given the comments associated with the negative votes, it may be challenging for the submitters to address the concerns about the scope assessed by many as being too wide. Standardization is a difficult task and the JCP (the Executive Committee in fact) played its role by pointing out the challenges ahead of such a JSR as it was envisioned by its submitters, and thus the risk of never completing. If anything this proves that the JCP is working as expected. For those disappointed that Java will not get a standard "Social Media API" (for now at least), let me remind you of the recent open-sourcing of DaliCore.

  • How can I operate on the active X display using a command in the console?

    - by G1i1ch
    I have problems where compiz freezes and I have to switch to another console(ctrl+alt+F1) to restart. But it would be easier if I could just do "$ compiz --replace" in the other console and not have to lose work or anything. But when I do this it says it can't open the display, makes sense because the display is open in console 7. Is there any way I can easily redirect a command to another console for it to be run there? Like for instance, be in console 1 and execute "$ compiz --replace" on console 7?

  • Cannot load a webpage with hp pavilion dv2000 laptop

    - by Andre'
    I am using an Ubuntu 12.04 cd to test out the os before I take the plunge, and I can't get webpages to load in the firefox application. When I look at the wireless settings, ubuntu says that my computer is connected to my home wireless network, but I am repeatedly prompted to enter my password (it keeps telling me that authentication is required by my wireless network). After a few rounds of this, Ubuntu seems to give up and tells me that wireless network is disconnected. Furthermore (I'm currently in ubuntu using a wired connection if it has anything to do with this), the wireless connection will randomly attempt to establish itself. I've entered rfkill list and all of the wireless devices therein say "no" - they're not blocked. I can connect to the network in Windows 7, so I don't think my network is the problem. Any suggestions?

  • How do I install ubuntu 12.04 over windows HP

    - by Cakemix
    I have an HP Desktop AMD 64 6-core processor 10GB RAM 1.5TB HDD and Windows 7 installed. I downloaded the 12.04 ISO and burned to a DVD. I want to install Ubuntu over Windows. I have recovery CD's made in case Ubuntu isn't for me and my family. During the install it says No root file system is defined please correct this from the partitioning table. In the box where I should be able to choose a partition, none are available to choose from, it is blank. I know that HP has decided to use 4 partitions. How do I go about deleting all the partitions using the LiveCD? I've never used GParted before and am a bit lost when it comes to anything to do with partitions.

  • possible to use an IP derived from Dynamic DNS in htaccess IP allow/deny commands?

    - by user115745
    On a website I manage, I want to use an .htaccess file to allow access to a certain administrative directory only from my home IP address, which is dynamically assigned by my ISP and therefore changes -- not regularly, but it does happen. I also have an account from DynDNS and have one of the auto-update clients making sure it always points to my actual home IP address. I don't actually host anything at home; I just have set up the Dynamic DNS account. Is there any way to combine these features: that is, is it possible write the .htaccess allow/deny commands at my outside webhost in a way that my home IP address is not hard coded into the command, but instead is somehow derived from the Domain Name that the DynDNS has assigned me, by doing a real-time lookup every time the directory's .htaccess file is hit? Thank you.

  • What factors help in getting a site indexed by Google fast?

    - by ekaj
    What should I do to get a site indexed on Google, fast? Taking example of Super User I just did a quick Google for a question that was 20 minutes old, to look for an answer, and it was already on Google Search - how is this possible? I glanced over this article which seems to suggest that SU has added RSS feeds (which SU has, but when I opened the feed the article says last posted 6 minutes ago, but when Googled it is 11 hours old) - which leads me to think (Based on that article, I don't know much about search indexing but I am reading at the moment) that most of this indexing is done thanks to the sitemap. is there anything else I am unaware of that helps SU questions get on Google so fast?

  • What method is used to create the password?

    - by Gortron
    Hello, I am developing on to a Groupon clone app called Couponic on behalf of a client. Can anyone help in pinpointing how Couponic generates user passwords? I want to be able to generate new passwords in the same method Couponic uses in a separate PHP script if possible, so that users of an existing site will also be able to log in to the Couponic site without re-creating an account. Couponic is built using the YII PHP framework, I can't find anything in the YII documentation. Any help would be greatly appreciated.

  • How to redirect a international domain to a subfolder on the English site without hurting Google rankings?

    - by ernest1a
    I have two sites: www.example.de www.main.com www.main.com is English version of www.example.de which is in German. I want to keep only www.main.com. For the English version I will keep www.main.com, but for German I want to move it to www.main.com/de. I am wondering what would be best solution for old www.example.de: Redirect everything from www.example.de to www.main.com/de using 301 redirect? Redirect everything from www.example.de towww.main.com/de/page-url-of-old-size.html? So each link actually get own address. Is that necessary or will Google realize where the page belongs on new site even if I redirect everything to home page? Any other solution, maybe just set in Google webmaster tools the new domain or anything like that?

  • How do I get HDMI out working on an Acer AC700 HDMI?

    - by Kyle
    I have installed Ubuntu on my Acer AC700 (Chromebook) using both the Cr-48 method and the script method both of which I think are the same. The only thing that does not work is HDMI out. I assume this is because it uses the Chrome OS kernel to boot so I have hoped that eventually it would update and work. I'm currently running 12.04 with Kernel 3.4.0 and still no luck. I've tried booting in recovery for Ubuntu and attempting to get Xorg to generate a new config but I don't know enough to do anything else and that didn't work. Am I the only one out there? Is there no one else who wants this to be possible Any help is greatly appreciated.

    My user is the Admin, it runs fine, not bugs or anything, I used Ubuntu Tweak for a few things like logging options and the sidebar and Unity Tweak for hotcornes and minimize window and that's about it.

  • Where to start when digging into an existing J2EE codebase?

    - by Jacob Krustchinsky
    I work for a company that produces enterprise applications to be used by schools and districts to manage all of their tests and standards data. Their existing application is written in J2EE and is very large. I personally am a seasoned PHP and Ruby = RoR developer and I have been asked to attempt to implement easily added but crucial features to an existing J2EE codebase. I am very familiar with Java SE and know the architecture of a web application well. What I am asking for is, will this suffice for the task ahead and what tips can you give me in digging into the code base and actually efficiently adding these new features? Is there anything important I need to know before beginning and what can I expect in terms of problems and issues coming from a Java SE, PHP, RoR background? Time isn't too much of an issue, I should have plenty of time to familiarize myself with J2EE.Please also note, syntax will not be a problem here.

  • Cannot access my own web page

    - by enflam3
    I am developing, learning and experimenting with php,html,javascript,flash and so on. Having web hosting and all of the cpanel, phpmyadmin and other utilities. One day, while updating information, connection between my computer and website just went down. I found out that it is only from this computer, where I cannot access anything. I don't know what is the reason I cannot access website, however this is what I have checked so far: Everything else opens normally, having problem only with my page. Cannot access FTP,cpanel or any kind of information related to the domain and hosting ipconfigs detects IP, but shows request timed out (so its not browser related) Turned off Firewall,AV, Rebooted computer Cleared caches,temp,cookies,histry with CCleaner Checked connectivity with both (wired,wireless) networks ISP has dynamic IP that has been changed about 3 times since issue Checked host file I am out of ideas and understanding what could cause this kind of issue, however couple minutes ago, found out that everything works with proxy server (when adding IP and port to the browsers) Can someone point out what should I check or try to get rid of this problem?

  • Laptop wakes while lid is closed and overheats

    - by user56601
    I'm running 12.04 on a toshiba L305D with athlon x2 (Already suspect this has something to do with it). My laptop will wake from suspend, presumably from wireless scanning. This is a serious bug as sleeping laptops are often inside bags, so the cooling system is effectively disabled. I can no longer seriously use Ubuntu when I have to worry about hardware damage every time I close the lid. There is shockingly lack of information about anything close to this. So many control panels have been removed or dumbed down, and everyone seems to want this behavior instead of the opposite, for servers or torrents of whatever. Well, most laptop users will 99% be likely to regularly put their laptop in a backpack or briefcase or other bag. Does anyone know how to fix this?

  • 13.10 Desktop - Stop Suspension on Lid Closure

    - by bpmitche
    I'm having a problem with power management settings on my ASUS K52-F Laptop. Upgraded from 13.04 to 13.10 earlier today; closing the laptop lid puts the laptop into suspension (even on AC Power - tried fixing it in gnome power settings, tried fixing it in Cinnamon power settings, tried changing it in DCONF-Editor, but no matter where I change the setting the laptop lid still suspends). After resuming from suspend, I restore to the gnome window/login manager (instead of Cinnamon login manager). Wifi doesn't reconnect, but the icon in Cinnamon shows that I'm connected. IFCONFIG shows that the interface is up and working normally, but still not reconnecting. ifconfig wlan0 down / up doesn't change anything. Any help would be greatly appreciated.

  • Am I personally liable for bugs in medical software I've developed as an employee? [closed]

    - by user466406
    Some background: I'm employed at a small, Australia-based web agency that is dipping it's toe into Mobile Application development (iOS). The project that I'm working on provides a way for users to save medication dosage information which is sync'd with a backend server. Users must agree to ToS, Disclaimer etc before using the application. This is my first iOS application, and the project is currently over budget. As a result, management is not devoting the resources to Q&A and is pushing instead for more features. I am an employee of the agency, that has been contracted by a non-for-profit. The application will probably be released under our agency's name, but we also have the option of releasing it as the not-for-profit. My question is, if there are bugs found in the application, and as a result a user takes an incorrect dosage of a medication, am I personally liable? Is there anything that I can or should do in order to protect myself personally?

  • Restricted Flow Of Power

    - by user13827
    I'm sure all is fine, but i need some reassurance. Last month my company launched consolidated two of their websites into one new website. www.fdmgroup.com and www.fdmacademy.com into a newly designed www.fdmgroup.com. Because the FDM Academy grew as it's own brand we decided not to just forward the domain to the fdmgroup website, but instead just mirror the new FDM Group website and use a canonical tags to the FDM Group domain (so the link juice will pass to the FDM Group domain pages) The website has be live for nearly a month and i don't believe any power has passed down through the FDM Group website to it's deeper pages even though 301 redirects from the legacy group and academy domains in place. I am also seeing the same problem on the FDM Academy domain, but i expect to see this as every page has a canonical to the same page on the Is there anything which is restricting the flow of power through the site, or am i just being impatient. Thanks in advance Jon

  • How do I repeatedly move an image by 1 pixel?

    - by Will
    I have a method that is moving a UIImageView called shootImg across the screen: -(IBAction)shoot{ if (appDelegate.shootInt > 0) { if (direction == 1) { shootImg.center = CGPointMake(shootImg.center.x+1, shootImg.center.y); appDelegate.shootInt = appDelegate.shootInt - 1; shootLabel.text = [NSString stringWithFormat:@"%d", appDelegate.shootInt]; } This does seem to work. But it only moves shootImage 1 pixel. What I want to do is make it repeatedly move 1 pixel. I tried a while loop but that didn't seem to work. I'm not using cocos2d or anything like that and if you need to see more code just ask. Thanks :)

  • Client Side Prediction

    - by user13842
    I have a question regarding Client Side prediction. Ive tried to search topics about my specific problem but couldn't find anything which really answered my problem. Most tutorials and explanations assume that the Client sends messages like "Move my player up by 1 Position", but what if i send messages like "Set my player's velocity to x"? Since it's hard to explain with text, i made a graphic explaining my problem. The main problem is, that the player sets his own velocity, due to Client Side Prediction, earlier than the Server. So if 2 different velocities overlap, the Server would get out of sync. How can i tackle that problem? Thanks a lot. Graphic: http://img27.imageshack.us/img27/6083/clientpred.png (Ignore the 5.5cm)
