• Jquery/JavaScript's role in MVC (zend)

  - by user7543288

  I have my doubts if this question should have went into the programmers.stackexchange.com or not…but I would like to ask all you experienced developers out there, how do you see the connection that jquery - javascript has with the MVC. How would you explain it to a n00b? does it bridge the communication between the View and the Controller? or what? I have done my research and I believe this is the best article explaining it http://www.alistapart.com/articles/javascript-mvc/ but I would like to hear your point of view..

• Are there any surveys on to what degree developers like or hate scrum?

  - by dparnas

  Background: During a conference an analyst pointed out in a tweet that developers hate scrum. Myself and another person responded that this was not the case, and started discussing different scenarios on why developers would dislike scrum. One of the scenarios where that lazy developers are not able to hide in a scrum project. They are constantly challenged by the team to contribute. This discussion resulted in a blog post and video http://elsewhat.com/2010/05/20/lazy-developers-hate-agile-and%C2%A0scrum/ I've gotten three comments which I've tried to answer in a neutral way, but they comments do point out that there are some people who loathe scrum (and I am always 100% certain they are not lazy developers). Question Have there ever been a survey among developers on to what degree developers like or hate scrum ?

• Video playing is slow on 12.04

  - by user58439

  I started using Ubuntu a very short time ago, and it was working perfectly! I upgraded to 12.04 yesterday, and today I realize that everything is running slow. For example, video streaming online, from sites such as Youtube is not working correctly, audio and video breaks constantly. I have a 64 bit system, with a Intel® Core™2 Duo, 2.10GHz × 2 . I don't know what more to add. I tried free -m on the terminal, it returned that I had only 524MB free from 3858MB. All that i have running at this point is Mozilla Firefox.

• Why does Linq to Entity Sum return null when the result set is empty?

  - by Hannele

  There are quite a few questions on Stack Overflow about the Linq to Entity / Linq to SQL Sum extension method, about how it returns null when the result set is empty: 1, 2, 3, 4, 5, 6, 7, and many more, as well as a blog post discussing the issue here. I feel it is an inconsistency in the Linq implementation. I am assuming at this point that it is not a bug, but is more or less working as designed. I understand that there are workarounds (for example, casting the field to a nullable type, so you can coalesce with ??), and I also understand that for the underlying SQL, a NULL result is expected for an empty result set. But because the result of the Sum extension for non-nullable types is also non-nullable, why does the Linq to SQL / Linq to Entity Sum behave this way?

• Cant install Ubuntu. How do you format a Windows HDD

  - by heldeman

  I have an HP 630, and would like to install Ubuntu. All goes well until the point where you have to choose how you want Ubuntu installed. I choose on the whole HDD, I want Windows off the HDD. I press enter and about 5 seconds later the CD tray open and the computer reboots. This happens over and over. How do I format this Window HDD completely to install Ubuntu 13.04. I have tried 3 different CD's and the same thing happens each time.

• Google Chrome triple sa part de marché en un an et aide Firefox à devenir numéro un en Europe au détriment d'Internet Explorer

  Google Chrome triple sa part de marché en un an Et aide Firefox à devenir numéro un en Europe au détriment d'Internet Explorer Internet Explorer est détrôné en Europe, une première sur un telle zone géographique. La faute à Firefox, bien sûr. Mais aussi et surtout à Chrome de Google. Le titre du navigateur le plus utilisé en Europe revient donc à Mozilla Firefox (d'après les chiffres du mois de décembre publiés par StatCounter, spécialiste des statistiques web). Mais en analysant ces résultats de plus prêt, on remarque que la part de marché de Firefox n'a absolument pas augmenté entre les mois de novembre et de décembre. Le navigateur a même perdu 0.4 point ...

• How can I add a custom item to the Sound Indicator?

  - by con-f-use

  One of the strength of Unity are the various standardized indicators. I want to customize the sound indicator with an additional menu entry that runs a small shell script. I'm not afraid of a little Python code and I hope someone can point me to the right subroutine in the right file. I suspect that will be fairly easy but all the indicators are just so bloated that I can't look through their code in a reasonable time. Any help is appreciated. I know it is possible as the marvelous Skype-Wrapper does it.

• Limitation of high level languages? [closed]

  - by user1705796

  My question may look bit philosophical and nonsense! But I need to know kind of instructions those are not well suitable in high level languages even in c? Or rarely use in the development of software? Like read/write content of CPU registers may useful in debugging programs. And access to cache memory required when developing OS (maybe I am wrong at this point). Is this kind of instruction available languages like Java, Python, C? I also have a second question: And Why all high level languages not having same uniform syntax; at-least same standard library interface name? In python there is and. Or operator is almost same as && and ||. I think Python is developed after C but space indentation is compulsory in Python. Why Python does not use brackets {}. I already know this question going to be highly down-voted.

• Charakter coding / programming

  - by Jery

  lately I tryed a few times to create charakters for some games, but at some certain point (especially when collision detection came in) everything became messy and the interaction between chars, the world and certain items had a lot of bugs. So here is my question, how do you ussualy keep track of actions that your charakter is allowed to do, or more in general do you have some links / advices how to set up a char efficiantly? I´m working on a char right now, who should at least be able to run, jump, pick items up and use different fighting animations. Most ideas I came up with until now use some kind of action.priority / action.duration system to determain whats possible and what not, or a "action-manager" which defines for every action what is possible from that action on but it all doesnt work that well together =\ thx in advance for some input

• Grub Doesn't Load after Update

  - by Parris

  Hi Everyone, After I updated ubuntu (I believe it was most likely a kernel update) and restarted I selected ubuntu from the windows boot loader (I am using wubi). At this point I would usually land on the grub loader; however, I see something about NTFS file not found and a couple other screens flash then the computer restarts. I have tried pressing ESC right after to try and get some options, but I think grub is just not found or something... Not sure what is going on.. Any help would be much appreciated :). Thanks!

• Distinguishing between sets of status reports

  - by user1769486

  I am working on an internal database monitoring system and am at a point where I sort of hit the wall in terms of application design. Basically I have an extensible plugin architecture where I shall have an OK, a warning or an error upon running a db verification. My first question whether it is sufficient to have only one status reported with an optional status message or provide the ability to have more than one returned (with attached messages) and then calculate an aggregated overall status. In particular in the latter case my second issue would be how to distinguish between two verification reports with the same status code (as it can come from different triggers). I would need to do this to see whether some change happened between the current and last verification. I could simply have string comparisons of the attached status messages mentioned above but that does not seem very reliable.

• mysql questions for beginners

  - by ankhseeker

  ok, I have a few questions regarding mysql. I am currently running ubuntu 12.04.4 LTS command line version. I am looking for a database that I can use. I am confused at this point because I am uninformed. mysql is just one database that is on the server? or can it contain several or many databases What programs do I use to access it on the server or is it a vt-100 type access? I understand that mysql comes with lamp? or ubuntu. I am thinking that it is already installed but not sure how to access it, but that is another question for later. Outside of the man pages and the ubuntu manual, is there a site for its setup and use? Thanks!

• How can I remap my keys to act like the Macintosh keyboard (like hold alt l + l click = r click)?

  - by jaorizabal

  I want my keyboard layout to act like a Macintosh keyboard. It's hard to use my computer after years on a mac. I want to disable my right mouse click, and replace it with alt + right mouse click. The alt key will also act like ctrl. I want my left ctrl to be the HUD key. I still want my super key to be the same. Can someone please make a script, or point me in the direction of a program to do all this with ease. If you were to make a script/whatever, can you please make one what will reverse all keyboard changes in-case I feel that it is not the same. I will add to the post if I miss anything. Thank you.

• Ubuntu installation time problem

  - by hellodear

  I am installing Ubuntu and I am stuck at a point. The step is when it is asking me to select partition. It is showing me error: "No file system is defined Please correct this from partitioning menu". I am getting this error when I am clicking "Install". I want Ubuntu to install in /dev/sda7 which is 226727 Mb. I have Windows 8 in my system and I want to dual boot the system. So how to correct this error? I want to allocate this whole partition to Ubuntu only. Secondly, What should I put in the option: "Device for boot loader installation"? By default it is somewhat like this: "ATA WDC WD5000..." something like this. Please tell my both these questions. I would be very thankful to you. Thanks.

• How to create a minimal installation in VMware Player for browsing?

  - by dbz_a

  I am trying to build a minimal vmware image to use for private browsing (also called a browser appliance). I have tried using images for other small linux distros, most of them are either too heavy (I do not want any other functionality than browsing and downloading) or outdated (DSL, various browser appliance images at vmware official site). I have downloaded the minimal Ubuntu install image (12MB) and was hoping to select only the needed pakcages while installing but it was not asking for my choices anywhere. I am new to the command line installation and I would be thankful if someone could point out how to install only needed packages, and what are the bare-minimum packages to browse internet (I plan to use only firefox and transmission)

• Does Ubuntu One offer Windows Live Sync type services?

  - by Raaaaay

  I'm an Ubuntu convert from Windows and I'm liking it very much. One of the few things I miss in Windows is their Live Sync. I don't know what it's like now or whether it still exists, but at the time (2008/2009), Windows Live Sync lets you sync folders between computers without uploading contents on their server. That is, only the metadata of the subscribed folders are uploaded (things like changelog etc.). I really liked that, and I was wondering if Ubuntu One has an option that does the same thing? At the moment it only seems to have the option to upload all file contents on the web, and I'd rather not do that. If Ubuntu One doesn't have the service similar to Windows Live Sync as described above, then I really recommend it. I would greatly appreciate it if someone can point me to the right place to make my recommendations. Thanks in advance!

• Books or resources about x86 64 assembly written in AT&T style?

  - by Gnijuohz

  I know what I'm asking for is quite specific and many would say if you know x86 assembly, this wouldn't be an issue. But now I'm taking a course that requires me to use x86 64 assembly in AT&T style and I'm not familiar with assembly in the first place. So I think if I can find some books or web resources about x86 64 assembly written in AT&T convention, it'll help me the most. But so far, I haven't found such books or detailed web resources yet. So can anyone point me to some good resouces? Advice on learning Assembly is also appreciated here!

• Java Preferential Treatment

  - by Jay

  I have icedtea6-plugin installed on my Ubuntu box. The weird thing is, when I am browsing the internet, certain website are able to use the Java and some websites are not. For instance, I am able to log in to my bank at nordea.dk. They use a Java applet to authenticate the user. But when I try to use keepvid.com, it says "Loading Java Applet". And then after a minute or two it says "Error: Please click here to download Java. If you already have Java, please restart your browser and try again." The thing is I've restarted my computer, closed and opened my browser(chromium) and none of it seems to help. Could someone please point me in the right direction to solve this problem? Thanks.

• Learning MySQL Query optimization

  - by recluze

  I've been doing web/desktop/server development for a while and have worked with many databases (mysql mostly). I've come to the point in my career when I need to have someone look at my queries because they're 'kind of slow'. I believe it's now time to start learning query optimization. While I know the basics of index and joins etc., I'm not familiar with how to use, say, the EXPLAIN output to improve performance of my queries. I have not been able to find any online material that starts with the basics and takes me to application. Getting a book is not an option right now so I'm looking for tips about how to proceed with this. I hope this question is general enough not to get closed.

• GUI is not displayed anymore

  - by mdobrinin

  I am running 12.04 LTS on a VM. I encountered a problem with the screen being black and the familiar orange background showing for a fraction of a second when clicking or resizing the screen. I had to shutdown the machine and now I have no GUI. I only get a black command-line interface. As some other posts suggest, I attempted: sudo service lightdm restart This doesn't work for me because it gets stuck at this point: Skipping profile in /etc/apparmor.d/disable: user.bin.firefox Skipping profile in /etc/apparmor.d/disable: user.sbin.rsyslogd * Starting AppArmor profiles [ OK ] Any ideas?

• Microsoft va-t-il devoir racheter Nokia pour pérenniser Windows Phone ? Le constructeur finlandais est de plus en plus dans la tourmente

  Nokia de plus en plus dans la tourmente Microsoft va-t-il devoir racheter le constructeur finlandais pour Windows Phone ? Nokia coule-t-il à pic ? Peut-être pas encore, mais le constructeur se rapproche dangereusement du point de rupture. Après avoir dévoilé de mauvais résultats prévisionnels (une perte d'exploitation de plus en plus importante qui dépassera les 3% du CA), et en dessous des attentes, l'action du groupe s'est littéralement écroulée de 18 % pour atteindre son plus bas depuis plus de 12 ans.

• What makes a language (or feature) "hackerish"?

  - by iCanLearn

  I was reading the comments and answers to this question, and among them I found this: "And Java never was cool, simply because it threw the hacking part out of programming" and this: "And javascript is very hackerish language so after developing your frontend you feel very constraint when you return to java." What's the "hacking part" in programming, and what makes a language "hackerish"? What are some good examples of languages and features in languages that you would call "hackerish"? (Someone might say that I shouldn't be confused by the word "hackerish", that's it's not really a "proper" English word or something like that, but that's besides the point)

• What is the better design decision approach?

  - by palm snow

  I have two classes (MyFoo1 and MyFoo2) that share some common functionality. So far it does not seem like I need any polymorphic inheritence but at this point I am considering the following options: Have the common functionality in a utility class. Both of these classes call these methods from that utility class. Have an abstract class and implement common methods in that abstract class. Then derive MyFoo1 and MyFoo2 from that abstract class. Any suggestion on what would be a better design decision?
