  • Common Javascript mistakes that severely affect performance?

    - by melee
    At a recent UI/UX MeetUp that I attended, I gave some feedback on a website that used Javascript (jQuery) for its interaction and UI - it was fairly simple animations and manipulation, but the performance on a decent computer was horrific. It actually reminded me of a lot of sites/programs that I've seen with the same issue, where certain actions just absolutely destroy performance. It is mostly in (or at least more noticeable in) situations where Javascript is almost serving as a Flash replacement. This is in stark contrast to some of the webapps that I have used that have far more Javascript and functionality but run very smoothly (COGNOS by IBM is one I can think of off the top of my head). I'd love to know some of the common issues that aren't considered when developing JS that will kill the performance of the site.

  • Writing Large Portions Of Code Then Debugging?

    - by The Floating Brain
    Lately I have been writing a game engine, and I have been writing a lot of "foundation stuff" (standard interfaces, modules, a message system ect.), but I have noticed a pattern, a lot of the stuff is interdependent and I can not debug until everything is done, hence I do not debug for about 3 to 5 hours at a time. I am wondering if this is an acceptable practice for this part of the project, and if not, if anyone can give me some advice? -----Update-----: I downloaded some code metrics tools, and my programs cyclomatic complexity is 1.52 which as I understand it is good, and should correlate to high cohesion, if I am wrong please correct me/

  • php+mysql account management software?

    - by kdavis8
    I need an account system added to my website as a plugin to all of my HTML pages. The account system plugin needs to,register new users, log in current users, remove users who want to disconnect service, and manipulate all of these things via database on my web server. However, I do not know how to program in the PHP language or create and manipulate MySQL databases. I want a program that can create and manipulate the MySQL database automatically for my website and handle also PHP calls automatically. Are there any open source freeware programs out there that i can use? If so what are the names of these freeware?

  • Can I install ubuntu on usb hdd without loosing data on it?

    - by Radek
    I have live-usb stick that I can boot latest live Ubuntu from. Then I have 160GB external WD hdd with few GB free of space. My notebook can't have any internal hdd so I was wondering if I can use my external one to install and boot Ubuntu and install new programs, save settings etc. without loosing (or moving around) any data on this external hdd. The best would be if I can somehow use the live-usb. I'm traveling so any "complicated" solution might be bit hard to implement. I do have an access to the Internet.

  • Ubuntu studio/xubuntu 12.04 instead of Ubuntu 12.04/12.10 for CAD/ arhcitectural workflow. Worth it?

    - by gabriel
    I am currently using Ubuntu 12.10. So, as described in the title I am planning to install Ubuntu studio. The programs i use are Blender, Maya 2013, NukeX, Bricscad, Sketchup (with wine) and also i am planning to install revit architecture through VirtualBox. Well, I am using a quad-core CPU and i want to have all the power of my system for rendering/modelling. So, i decided to try a more lightweight desktop than unity. Also, what made me to decide this, is that when i tried to install Bricscad v12 the program does not work. So, i thought that if i want something more professional for my work i should have only LTS versions of lightweight Ubuntu. So, my 2 questions are :1) Worth it? 2) Can i have global menu(close,minimize,maximize buttons, menu) like ubuntu/unity? Thanks

  • Why does my CD Tray keep popping open?

    - by Anton
    I have Ubuntu server - Ubuntu 10.04.3 LTS and I can't figure out why my CD tray is opening all the time. I have looked into /var/log/auth.log, cron list and found nothing. The eject command closes tray and then it gets opened again. The server has a LAMP (Linux-Apache-MySQL-PHP) setup and I can't afford to restart it now. How can I find out who or which program is popping the tray open? Which programs can cause this behavior?

  • Broken Gnome panel after Ubuntu Update

    - by Asaf
    Like every single update on Ubuntu system, my graphical system is completely broken after updating to version 11.10 http://i.imgur.com/YIHfA.png As shown in the image, the date is in the middle of the panel, There are many icons missing (network connection icon, skype) There's no right click menu when I try to right click on the panel and many programs don't have their menus (file,edit,view... those things). How do I fix this? I have gnome-panel, I don't want Unity and I'd rather install windows 95 before I switch to it.

  • Do you believe it's a good idea for Software Engineers to have to work as Quality Assurance Engineers for some period of time?

    - by Macy Abbey
    I believe it is. Why? I've encountered many Software Engineers who believe they are somehow superior to QA engineers. I think it may help quench this belief if they do the job of a QA engineer for some time, and realize that it is a unique and valuable skill-set of its own. The better a Software Engineer is at testing their own programs, the less cost in time their code incurs when making its way through the rest of the software development life-cycle. The more time a Software Engineer spends thinking about how a program can break, the more often they are to consider these cases as they are developing them, thus reducing bugs in the end product. A Software Engineer's definition of "complete" is always interesting...if they have spent time as a QA engineer maybe this definition will more closely match the designer of the software's. What do you all think?

  • compiz hiding unity and all menus

    - by Lennart Guldbrandsson
    After updating to Ubuntu 11.10, I was severly disturbed by Dash and wanted to go back to Ubuntu Classic. So I tried to read up, and found Compiz SettingsManager. In there, I clicked "on" never hide menus. For some reason this made all my menus at the top of the screen (volume, network, my login identity, and shutoff, etc) disappear - as well as the quickstart menu to the left (Unity). I am not very technical, so I have a hard time finding any programs now, and I just got on the internet by clicking on a link in a document, that I was fortunate to have on my Desktop. Without it, I wouldn't be able to ask for help. What I wish for is a) to get back the menu at the top, b) to restore the Ubuntu Classic without the irritating launcher and Dash, c) these two things to not disappear every time there is a new version of Ubuntu. Any help is greatly appreciated.

  • Ransomware: Why This New Malware is So Dangerous and How to Protect Yourself

    - by Chris Hoffman
    Ransomware is a type of malware that tries to extort money from you. One of the nastiest examples, CryptoLocker, takes your files hostage and holds them for ransom, forcing you to pay hundreds of dollars to regain access. Most malware is no longer created by bored teenagers looking to cause some chaos. Much of the current malware is now produced by organized crime for profit and is becoming increasingly sophisticated. How Ransomware Works Not all ransomware is identical. The key thing that makes a piece of malware “ransomware” is that it attempts to extort a direct payment from you. Some ransomware may be disguised. It may function as “scareware,” displaying a pop-up that says something like “Your computer is infected, purchase this product to fix the infection” or “Your computer has been used to download illegal files, pay a fine to continue using your computer.” In other situations, ransomware may be more up-front. It may hook deep into your system, displaying a message saying that it will only go away when you pay money to the ransomware’s creators. This type of malware could be bypassed via malware removal tools or just by reinstalling Windows. Unfortunately, Ransomware is becoming more and more sophisticated. One of the latest examples, CryptoLocker, starts encrypting your personal files as soon as it gains access to your system, preventing access to the files without knowing the encryption key. CryptoLocker then displays a message informing you that your files have been locked with encryption and that you have just a few days to pay up. If you pay them $300, they’ll hand you the encryption key and you can recover your files. CryptoLocker helpfully walks you through choosing a payment method and, after paying, the criminals seem to actually give you a key that you can use to restore your files. You can never be sure that the criminals will keep their end of the deal, of course. It’s not a good idea to pay up when you’re extorted by criminals. On the other hand, businesses that lose their only copy of business-critical data may be tempted to take the risk — and it’s hard to blame them. Protecting Your Files From Ransomware This type of malware is another good example of why backups are essential. You should regularly back up files to an external hard drive or a remote file storage server. If all your copies of your files are on your computer, malware that infects your computer could encrypt them all and restrict access — or even delete them entirely. When backing up files, be sure to back up your personal files to a location where they can’t be written to or erased. For example, place them on a removable hard drive or upload them to a remote backup service like CrashPlan that would allow you to revert to previous versions of files. Don’t just store your backups on an internal hard drive or network share you have write access to. The ransomware could encrypt the files on your connected backup drive or on your network share if you have full write access. Frequent backups are also important. You wouldn’t want to lose a week’s worth of work because you only back up your files every week. This is part of the reason why automated back-up solutions are so convenient. If your files do become locked by ransomware and you don’t have the appropriate backups, you can try recovering them with ShadowExplorer. This tool accesses “Shadow Copies,” which Windows uses for System Restore — they will often contain some personal files. How to Avoid Ransomware Aside from using a proper backup strategy, you can avoid ransomware in the same way you avoid other forms of malware. CryptoLocker has been verified to arrive through email attachments, via the Java plug-in, and installed on computers that are part of the Zeus botnet. Use a good antivirus product that will attempt to stop ransomware in its tracks. Antivirus programs are never perfect and you could be infected even if you run one, but it’s an important layer of defense. Avoid running suspicious files. Ransomware can arrive in .exe files attached to emails, from illicit websites containing pirated software, or anywhere else that malware comes from. Be alert and exercise caution over the files you download and run. Keep your software updated. Using an old version of your web browser, operating system, or a browser plugin can allow malware in through open security holes. If you have Java installed, you should probably uninstall it. For more tips, read our list of important security practices you should be following. Ransomware — CryptoLocker in particular — is brutally efficient and smart. It just wants to get down to business and take your money. Holding your files hostage is an effective way to prevent removal by antivirus programs after it’s taken root, but CryptoLocker is much less scary if you have good backups. This sort of malware demonstrates the importance of backups as well as proper security practices. Unfortunately, CryptoLocker is probably a sign of things to come — it’s the kind of malware we’ll likely be seeing more of in the future.

  • What are some recommended video lectures for a non-CS student to prepare for the GRE CS subject test?

    - by aristos
    Well the title kinda explains all there is to explain. I'm a non-cs student and was preparing to apply PhD programs in applied mathematics. But for my senior thesis I've been reading lots of machine learning and pattern recognition literature and enjoying it a lot. I've taken lots of courses with statistics and stochastics content, which I think, would help me if I get accepted to a program with ML focus, but there are only two CS courses -introduction to programming- in my transcript and therefore I decided to take the CS subject test to increase my chances. Which courses do you think would be most essential to have a good result from CS subject test? I'm thinking of watching video lectures of them, so do you have any recommendations?

  • Problem in Kubuntu: Default browser never opens

    - by user170852
    I'm using Kubuntu, and I switched the default browser to my favourite one. The thing is, when I did this, both my Twitter clients stopped working. Now each and every Twitter client I download and install fails to open any web browser to finish my account authorization. It's impossible they're all broken, so I reset my default browser to rekonq and it works well as a default browser, but still can't login to twitter from any client. In fact, every button in every program that should open a browser window (like Amarok with the "like on last.fm" button) does nothing. So I think there may be a problem with my system but I can't figure out what is it. My user is not in the admin group (it's a shared user), I have an admin user but I only use it to install programs. Could that be the cause? Also, hitting alt+F2 and writing man:file (enter) opens a rekonq window normally.

How do I completely get rid of the Ubuntu installation? Thanks.

  • Problem with graphic Ubuntu 12.04 (not sure if it's because of the graphic driver)

    - by Duy Nguyen
    Ubuntu 12.04 was functioning properly . Then after an update, some graphic elements stop working properly. I could not launch programs that has 3D elements. Work space switcher's window displays 2D window instead of a 3D like usual. In Details menu, the Graphic row is blank. I am using Intel GMA 4500MHD graphic card. I am guessing that the driver is not properly installed? Anyone has the same issue? Please help!

  • What features of old computers helped you learn to be a better programmer?

    - by David Cary
    What features of old computers helped you learn to be a better programmer -- but don't seem to be available on new computers? I imagine that, while educational, you are really glad some features are gone, such as programs ran so slowly that I could almost see each pixel being plotted, so I got a visceral feel for the effect of various optimizations. I imagine other features you may be a little nostalgic for, such as I could turn on the computer, and write a short program that printed "Hello, World" on the printer, before ever "booting" a "disk". (I'm hoping that this is constructive enough to avoid the fate of the " What have we lost from computers 20 years ago ?" question).

  • Why should most logic be in the monitor objects and not in the thread objects when writing concurrent software in Java?

    - by refuser
    When I took the Realtime and Concurrent programming course our lecturer told us that when writing concurrent programs in Java and using monitors, most of the logic should be in the monitor and as little as possible in the threads that access it. I never really understood why and I really would like to. Let me clarify. In this particular case we had several classes. Lift extends Thread Person extends Thread LiftView Monitor, all methods synchronized. This is nothing we came up with, our task was to implement a lift simulation with persons waiting on different floors, and theses were the class skeletons that were given. Then our lecturer said to implement most of the logic in the monitor (he was talking about class Monitor as THE monitor) and as little as possible in the threads. Why would he make a statement like that?

  • How to composite videos and make animations in Ubuntu?

    - by Naveen
    Well, I'm not talking about programs like NukeX, Cinelerra, Jahshaka because they aren't either free or feature rich. I have seen couple of cool videos done on Linux platform, most likely to be Ubuntu. How Linux is Built - Linux Foundation Ubuntu 12.10 Beta Overview - OMG! Ubuntu What is the magic application they are using to composit those videos..? Can upcoming LightWorks workout these effects...? Is there any Linux native OpenGL based application to deal with particles, just like Particle Illusion for Windows? Thanks!

  • How do you learn a new programming language?

    - by Naveen
    I am C++ developer with some good experience on it. When I try to learn a new language ( have tried Java, C#, python, perl till now) I usually pickup a book and try to read it. But the problem with this is that these books typically start with some very basic programming concepts such as loops, operators etc and it starts to get very boring soon. Also, I feel I would get only theoeritcal knowledge without any practical knowledge on writing the code. So my question is how do you tacke these situations? do you just skip the chapters if its explaining something basic? also, do you have some standard set of programs that you will try to write in every new programming language you try to learn?

  • Do I have to completely reinstall Ubuntu now that it won't boot?

    - by Dave M G
    I just tried installing software called Teamviewer. It said there was some kind of error with unresolved dependancies. Then I realized I was trying to install the 32 bit version, but I needed to install the 64 bit version. So I tried that, and I got an error saying that Ubuntu needed to do a partial upgrade. I thought that was weird, so I just wanted to abandon installing anything and get out of this. I exited all programs and rebooted, and now I can't get back into Ubuntu. After the GRUB screen I get a black screen and no login options. If I boot into recovery, I get the following screen: I booted up a live CD of 12.04 to see if that could help, but it seems the only option is to completely reinstall Ubuntu. Can I repair this in any way, or is my only option to make a fresh install?

  • Will mono be carried forward by upgrading to 12.04?

    - by vasa1
    I plan to upgrade from 11.10 to 12.04 when 12.04 is released. I noticed from my previous experience in upgrading from 11.04 to 11.10, that Synaptic, which was dropped in 11.10, was retained on my system presumably because I upgraded from 11.04 (which did have Synaptic by default) and didn't do a new install. Given that Synaptic was retained, my question relates to mono. According to the list here, I don't have any programs that need mono. (I've just purged Banshee.) If I don't remove mono, will it be carried forward when I upgrade to 12.04 just like Synaptic was? If the suggestion is to remove mono before the upgrade to 12.04, is sudo apt-get purge libmono* libgdiplus cli-common libglitz-glx1 libglitz1 still the recommended way to remove mono-associated material from 11.10?

  • How do I consistently activate USB speakers

    - by Andrew.Healy
    I have a pair of Ricco USB speakers. As these are external, I sought to use them with 11.10. They are recognised by 'aplay -l' and Pulseaudio- I have selected them, but, have to reset the volume, every time I log on. I can also only recieve feedback and sound from apps and programs- like Kaffeine- on this boosted volume- I cannot get System Sounds, like logon or logoff. I have tried the alsamixer install that used to work, to no effect. Is their an app that I should be trying or is this feat impossible ? I have tried to delete all the files in .pulse and rebooting or just deletion of the entire .purge directory, as Michael K suggested- neither work as the directory is automatically rewritten on reboot. Ideas?

  • How to unmount a virtual cd/dvd in Ubuntu 11.1o

    - by P J Reil
    I'm new to Ubuntu 11.10 and have absolutely no idea what I'm doing. I don't now how but in downloading and fooling around with a virtual cd/dvd program I seem to have inadvertently installed it. I had to shut down my computer for a while and when I re booted it all my files and my setup was gone. I have a brand new 11.10 setup with all the programs installed that I originally had but no files or bookmarks etc.. I'm not sure, but I think I'm running in a virtual cd/dvd. I don't know how to determine if I am or not and can't boot up in my original setup. Can anyone help me?

  • What is the benefit of writing to a temp location, And then copying it to the intended destination?

    - by Devdatta Tengshe
    I am writing an application that works with satellite Images, and my boss asked me to look at some of the commercial application, and see how they behave. I found a strange behavior and then as I was looking, I found it in other standard applications as well. These Programs first write to the temp folder, and then copy it to the intended destination. Example: 7zip first extracts to the temp folder, and then copies the extracted data to the location that you had asked it to extract the data to. I see several problems with this approach: 1.The temp folder might not have enough space, while the intended location might have that much space. 2.If it is a large file, it can take a non-negligible amount of time for the copy operation. I thought about it a lot, but I couldn't see one single positive point to doing this. Am I missing something, or is there a real benefit to doing this?
