• Why can we delete some built-in properties of global object?

  - by demix

  I'm reading es5 these days and find that [[configurable]] attribute in some built-in properties of global object is set to true which means we can delete these properties. For example: the join method of Array.prototype object have attributes {[[Writable]]:true, [[Enumerable]]: false, [[Configurable]]: true} So we can easily delete the join method for Array like: delete Array.prototype.join; alert([1,2,3].join); The alert will display undefined in my chromium 17,firefox 9 ,ie 10,even ie6; In Chrome 15 & safari 5.1.1 the [[configurable]] attribute is set to true and delete result is also true but the final result is still function(){[native code]}. Seems like this is a bug and chromium fix it. I haven't notice that before. In my opinion, delete built-in functions in user's code is dangerous, and will bring out so many bugs when working with others.So why ECMAScript make this decision?

• Core dump utility for .NET

  - by Dave

  In my past life as a COBOL mainframe developer I made extensive use of a tool called Abendaid which, in the event of an exception, would give me a complete memory dump including a formatted list of every variable in memory as well as a complete stack trace of the program with the offending statement highlighted. This made pinpointing the cause of an error much simpler and saved a lot of step-through debugging and/or trace statements. Now I've made the transition to C# and .NET web development I find that the information provided by ASP.NET only tells half the story, giving me a stack trace, but not any of the variable or class information. This makes debugging more difficult as you then have to run the process again with the debugger to try and reproduce the error, not easy with intermittent errors or with assemblies that run under the likes of SQL Server or CRM. I've looked around quite a lot for something that does this but I can't find anything obvious. Does anyone have any idea if there is one, or if not, what I'd need to start with in order to write one?

• Forking project on Github etiquette

  - by Mike Wills

  There is a project on Github that I mostly like and want to use. There are a few things I want to do differently/remove that doesn't make sense for what I want/need. Also I want to add a few things as well. As I understand it, I should fork the project and I can make whatever changes I want and push back to my fork. From there, I also want to occasionally pull into my fork the changes from the original project so I get the latest bug fixes/features. Am I off-base of how I think it should work? How would bring in the changes from the original project?

• Unity launcher autohide leaves "ghost" behind?

  - by Hailwood

  In 12.04 I had the launcher set to autohide, which worked perfectly. However in 12.10 I am getting a strange "ghost" issue. Take this screenshot, with me having a maximised google chrome window, mousing over the back button. As well as this, I also get another ghosting issue when I have the panel set with an opacity, whereby whatever is in approximately the middle left of the screen gets mirrored up to to panel, but only when I move/switch to a window. But that one is not so annoying as the autohide bug, how can I fix that?

• 11.10 runs really choppy and slow, but not if I choose "Gnome Classic"

  - by Ingram

  I'd like to use Unity with Ubuntu 11.10, but everything from Unity runs really choppy and slow. I have an ATI graphics card and I have installed the drivers through "Additional Drivers". The drivers work, as I can play 3d games flawlessly. When I drag the mouse box around or drag windows around, it is really choppy. I previously had Ubuntu 10.10 and everything worked fine. I installed gnome 3 on 11.10 and it does the same thing Unity does, very choppy and slow graphics. However, if I choose Gnome Classic, everything is fine. I can drag the mouse box all around with no problems. I can drag windows around and it looks and feels great. Is this a bug with Unity? Are others experiencing this? Or is there something I can do to fix this?

• What features would you like to have in PHP? [closed]

  - by StasM

  Since it's the holiday season now and everybody's making wishes, I wonder - which language features you would wish PHP would have added? I am interested in some practical suggestions/wishes for the language. By practical I mean: Something that can be practically done (not: "I wish PHP would guess what my code means and fix bugs for me" or "I wish any code would execute under 5ms") Something that doesn't require changing PHP into another language (not: "I wish they'd drop $ signs and use space instead of braces" or "I wish PHP were compiled, statically typed and had # in it's name") Something that would not require breaking all the existing code (not: "Let's rename 500 functions and change parameter order for them") Something that does change the language or some interesting aspect of it (not: "I wish there was extension to support for XYZ protocol" or "I wish bug #12345 were finally fixed") Something that is more than a rant (not: "I wish PHP wouldn't suck so badly") Anybody has any good wishes? Mod edit: Stanislav Malyshev is a core PHP developer.

• Avast Antivirus Crashes

  - by user67966

  Well I have installed avast anti virus on Ubuntu 12.04. But after updating, it crashes! So I have made some tweaks like below: 1) I pressed press Ctrl+Alt+T and opened Terminal. When it opened, I ran the command below. sudo gedit /etc/init.d/rcS 2) typed my password and hit enter 3) when the text file opens add the line: sysctl -w kernel.shmmax=128000000 4) made sure the line you added is before: exec /etc/init.d/rc S 5) This is how it should look like: Code: #! /bin/sh # rcS # # Call all S??* scripts in /etc/rcS.d/ in numerical/alphabetical order # sysctl -w kernel.shmmax=128000000 exec /etc/init.d/rc S 6) save it 7) Reboot My question is. Did I do anything wrong. I mean as I have made some tweaks,will it lower the security of avast down like viruses do! Please if you are a programmer check this if it contains bug or harmful intentions...Thanks.

• No lock screen when the right click menu is open

  - by Shivram

  I just found that the lock screen on my laptop does not show up when the right click menu is open. I discovered this when I pressed the right click button accidentally while closing the lid and the laptop went to sleep, but the lock screen never showed up when I opened the lid again. I am also not able to lock the system manually(with ctrl+alt+L) when the right click menu is open. Is this by design or is it a bug? I would assume that the screen should be locked automatically when the computer goes to sleep, but this doesn't seem to be the case. Anyone have any suggestions? My specs are: Dell Vostro 1500, Ubuntu 12.10

• Dimming the backlight is irreversible on a Samsung Q210 notebook, what do I do?

  - by user27304

  I'm new to the community, although I have been using Ubuntu since 2010. I have a Samsung Q210 notebook; Specs: Intel® Core™2 Duo CPU P8400 @ 2.26GHz × 2 4 Gigs RAM Nvidia 9200m GS (although system information in Ubuntu doesn't know) 194 GB HD OS: Ubuntu 11.10 Kernel is 3.0.0-12-generic-pae Although Samsung seems to be infamous for problems with Ubuntu, after upgrading to Oneiric, finally the FN Brightness Buttons are recognized. The only problem is, after dimming the backlight for a fixed amount of steps (3 or 4, I dare not count now because that would mean rebooting because I can't see anything), the display goes completely dark and using the FN buttons to brighten the backlight does not work anymore (before reaching that threshold, going brighter after dimming works). Now what do I do? File a bug report? If not, what then? If yes, how? Not sure... guess I should ask here first.. thanks for answering in advance.

• Why is Claws Mail starting in offline mode?

  - by Thanks

  I am sorry if this is not the best place to ask this, but hopefully someone might be able to help. After I upgraded to Ubuntu 11.10 from 11.04, Claws Mail 3.7.10 began starting in offline mode. It continues to do so upon every startup. I have searched and searched but cannot find any option that might affect this. Am I overlooking the option? Is this a bug with the current versions of Claws Mail and Ubuntu? Or is there some other way to fix this? Thank you.

• Why does Google Analytics show false referrals?

  - by Peter Merrill

  Ever since Google revamped their Analytics interface I've been noticing a weird "bug" while viewing the "Real-Time" overview area. From this area I can obviously see live stats of visitors to my website but when I visit my website by opening a new tab (Chrome) and manually visit website the real time stats sometimes look like the image linked below. http://i.stack.imgur.com/mfniY.png Is there any reason why Google is saying that I was referred by Stack Overflow when I'm visiting my website from a new tab? Could this be something do to with how I installed the analytics on my site or could this be an issue with browser cookies? Have anyone else noticed this? I am mainly concerned about this because in the standard reporting area of my Analytics panel my referral stats are getting thrown off every time I visit my own website.

• Cinnamon Settings blank after update

  - by Seth Balmore

  Using Ubuntu 12.04 with the cinnamon desktop, I installed the most recent updates and now when I open "System Settings" the entire window appears as a blank white screen. The headers for APPEARANCE, PREFERENCES, and HARDWARE are present, but the usual icons for *Background, *Hot Corners, *Printers, etc. are no longer visible. Some of these settings can still be altered via the terminal: cinnamon-settings backgrounds cinnamon-settings applets cinnamon-settings mouse and touchpad But other commands, such as cinnamon-settings hot corners are met with an error. This is obviously a problem with cinnamon, so I just want to bring it to attention and find out when they plan on fixing the bug. A workaround can be found on the web, but it seems way to risky to rely on.

• Debug in Eclipse - ClassNotFoundException

  - by lmsasu

  Hi all, when i debug in Eclipse a simple console application, I get a lot of ClassNotFoundException lines in the debug Window. It is not an error, somewhat lower in another pane I get "Source not found.". I understand that it is because the source code of the required class is not available, buI would like to skip over these lines... I have to press a lot of times the "step over" or "step out" button to get out of these states. What can I do in order to avoid these useless lines at all? Thanks

• What has been your experience with paid support from Canonical ?

  - by gabkdlly

  I am considering buying "Ubuntu Desktop Support" from Canonical for 2 reasons: I have a couple of issues that I would like professional help with. ( Specifically a recurring kernel panic, and a slow wireless connection. ) I would like to lend a helping hand toward supporting Ubuntu financially. However, I am a bit worried that once I transfer the money, they will end up just referring me to the bug tracker on Launchpad. Also, free support options like this site have the pleasant property that they are open to the internet, meaning that if my issue gets fixed, it is more likely to help others with the same problem. What does paying for support from Canonical actually get you ?

• Bluetooth mouse lag on high cpu load ubuntu 11.04 12.10

  - by sirkubax

  I have just migrate to Ubuntu 12.10 and I have noticed that I have huge problem with my bluetooth mouse left click button on a high load (wired, but scroll and right button are not affected) (I think powersave cpu mode affect that more than cpu load) It just not "trigger the interrupt". Mouse is laggy, click are not reggisterd. I can not work like that. At the same time, my touchpad and usb mouse works great. How to check that - limit cpu frequency (I use powersave and ondemend mode) I now wonder, what should I log, check, measure, to capture enough data to fill bug report. Any suggestions? greetings sirkubax

• Test descriptions/name, say what the test is? or what it means when it fails?

  - by xenoterracide

  The API docs for Test::More::ok is ok($got eq $expected, $test_name); right now in one of my apps I have $test_name print what the test is testing. So for example in one of my tests I have set this to 'filename exists'. What I realized after I got a bug report recently, and realized that the only time I ever see this message is when the test is failing, if the test is failing that means the file doesn't exist. In your opinion, do you think these $test_name's should say what the test means if successful? what it means if it failed? or do you think it should say something else? please explain why?

• Ubuntu reports low battery capacity on my Dell Vostro

  - by Jeff

  I have a Dell Vostro 1500. Before I wiped Windows XP off my hard drive in 2009, I had a full ~7 hrs battery capacity. I installed Ubuntu 9, and the capacity immediately dropped to about 27% (and has since decreased to about 11%). I couldn't figure out what to do, so I've just lived with the 20-30 minute battery life ever since. I upgraded to Ubuntu 10, and the issue remained. I wiped my hard drive clean again and installed Ubuntu 11, and the issue still remains. I tried what they told me in the forum here, but it didn't do anything. Is it possible for a battery to suddenly lose most of its capacity?? Or is there a bug in the power management software?

• RabbitVCS displaying unchanged files on commit

  - by misterjinx

  I have a strange problem with RabbitVCS. I'm inside a working copy directory and I want to commit some files. When I click the commit button, the commit window shows up, but there is a strange situation. Even though I have modified just a few files, the commit window is displaying all the files and directories inside working copy and the checkbox is ticked for each of them, like those files need to be committed. But those files were not changed and already exist in the repo. Please see the image below to understand what I'm saying (the only file that is unversioned/was changed is .htaccess, therefore it should have been the only file listed there). Has this happened to anyone ? It is a bug with RabbitVCS (and probably a solution exists) or am I doing something wrong ?

• Hide all normal windows shortcut is not working in Ubuntu 13.10

  - by Vladislav Ivanishin

  Hide all normal windows shortcut is not working. It is currently set to Alt+Ctrl+D. And changing the shortcut doesn't help (tried Super+D, Alt+Esc). However other shortcuts work fine (even from the same Navigation tab). I guess the question is a duplicate of this which is unanswered. Update: It works exactly one time after reboot. I can minimize windows and even bring them back using the combination but only once. Also switching keyboard layout shortcut stopped working, but as I can see it's a known bug.

• How much should I charge for a web app

  - by Kostas

  I am a freelance web developer and I am working on a PHP/MySQL/Javascript based project. It's a web app that uses a custom CMS with user types, followers system, search forms, blogs, social integration. It will take about 3 months to finish, according to a roadmap I make (based on current development stage) and about a month after that for bug fixing and testing. So I have to tell them a price. What price range you think it's appropriate?? (It's a good regular client, so I want something reasonable) Can you give me some ideas?? Thanks.
