• Why can't the Unity panel be hidden?

  - by newboldrob

  I am a light Linux user. I have Natty installed on my netbook and used to have it dual-booted on my Windows 7 PC. After a total refresh of my notebook off came Ubuntu and I'm back to basics over there. But HERE (I'm running Natty on a HP-Mini) I've decided to poke around a bit to get the best user experience on this little thing. I really like the Unity interface but really hate the static Unity Panel. I have no clue why it's even necessary to be on globally. After all, in the classic interface, both panels can autohide or get filed aside with buttons on either side of the bar. On a 10" screen, real estate is at a premium. What intrinsic purpose does the static unity panel hold for the OS? There has to be a great reason for this thing to HAVE to be here. It ONLY goes away in fullscreen apps and I can't use everything fullscreen Why can the unity panel not be hidden?

• Ubuntu ver 14.04 Network discovery not showing up on windows 8 but on windows 7

  - by Schwabber

  I have an old PC that is now my new Ubuntu machine. Currently I was working on sharing a drive so that backups and streaming could take place. I have it set up perfectly on my windows 7 laptop (able to read and write to it). For some reason however my wife's windows 8 laptop is not showing up on the Ubuntu and vice versa. I turned on network discovery on the win8 machine, but that didn't help. Thanks in advance edit- I have my win7 and win8 in the same homegroup and both can see each other in the network. Also the workgroup is the same.

• Google won't display site

  - by Markasoftware

  My website (markasoftware.getenjoyment.net) doesn't seem to be indexed properly by Google (I haven't tried other search engines). When I type in the URL of my site it appears right at the top of the list like it should. When I type in the entire contents of the title, however, the site doesn't appear! The title is quite long (Thermonuclear War Game Online: Thermonuclear War By Mark) and it has little (if any) competition. Have I been punished by Google for some reason, or is it something else? I have received zero hits from search engines. Can someone tell me why my site down't appear?

• Reasons for Pair Programming

  - by Jeff Langemeier

  I've worked in a few shops where management has passed the idea of pair programming either to me or another manager/developer, and I can't get behind it at all. From a developer stand-point I can't find a reason why moving to this coding style would be beneficial, nor as a manager of a small team have I seen any benefit. I understand that it helps on basic syntax errors and can be helpful if you need to hash something out, but managers that are out of the programming loop seem to keep seeing it as a way of keeping their designers from going to Facebook or Reddit than as a design tool. As someone close to the development floor that apparently can't quite understand from a book tossed my way or a wiki page on the subject... from a high level management position, what are the benefits of Pair Programming when dealing with Scrum or Agile environments?

• How to examine the speed of your code results?

  - by Goma

  Hi. Whatever was your choice PHP, ASP.NET, Ruby On Rails or even JSP. You know that you can develop a website to give a specific result or to do some tasks in many ways. I mean you can change your code to make it shorter (or for any other reason) but to give the same result. In this case how do you test which code was faster to excute so you choose it to make your website faster? I mean do you have any tools or ideas in how to test the time of execution for your code and compare it with time of execution after you do some edit?

• How can I restart compiz from tty? (& Related, how can I set up a fallback WM?)

  - by Jon

  So I'm testing Natty, and Compiz keeps crashing on me. I expect this sort of thing from alpha software, of course, but it doesn't always give me the option to restart compiz, and for some reason doesn't have a fallback WM configured. Without a window manager, all my programs are still running, but they're not accepting input from the keyboard, and I can't switch between them. I can, however, press Ctrl+Alt+F1 and get a terminal, and I can killall Xorg to reset everything, but I'd rather just reset compiz if possible. If I try typing compiz --replace there in the tty, it complains "fatal--couldn't open display." Is there a way to have tty1 restart compiz? Like compiz --replace --display=something? Additionally, is there a way to configure a fallback window manager so that there's an easier way to recover from compiz crashing?

• Why don't 8.04 panel launchers work on 10.04

  - by Android Eve

  I copied my panel launchers verbatim from 8.04 to 10.04, residing in both systems in the same path: $HOME/.gnome2/panel2.d/default/launchers However, for some reason, they are not visible on 10.04's GNOME panel. Why? In my attempts to troubleshoot the problem I: Verified that copied 8.04 launchers have same permissions as manually created 10.04 launchers (-rwxr-xr-x). Added the first line as: #!/usr/bin/env xdg-open Logged off, then logged on. Rebooted. None of the above helped. So the question remains: Why? And how do I make them work?

• Why make the login page to a single page application a separate page?

  - by ryanzec

  I am wondering why it seems to be popular to have the login page of a SPA be a separate page that is not page of the SPA (as in loaded and send data through ajax requests)? I only thing I can think of is security but I can't think a specific security reason. I mean the only thing that come to mind is that if your login page in part of the SPA, it sends the username/password through ajax which can be seen by such tools like firebug or web inspector however even if you send it as a normal POST request, there are other tools that can easily capture this data (like fiddler, httpscoop, etc...). Is there something I am missing?

• dovecot main process terminated with status 89

  - by G. He

  I'm trying to configure dovecot/imap to run without SSL. I set ssl = no in 10-ssl.conf in /etc/dovecot/conf.d. However, with this setting, dovecot dies right away when it is started. I checked the log file and found the following: dovecot main process (4895) terminated with status 89 What does it mean? Is there a way for dovecot to run without ssl? The reason I do NOT want ssl is that my outlook complains the certificate cannot be verified. It is really annoying. And I only run the server on a very small lan and don't need that extra security.

• Are IE9 really good ?

  - by anirudha

  IE9 started a campaign for kill IE6 from the core because they know that IE6 is a big trouble or  problem for them for promote 9 version of IE. so they started a campaign for killing IE6. next time they kill IE 7 , 8,9 whenever they found this old version have a big problem for them to promote next version of IE.   Why they not make a update system who automatically update the browser and tell user to restart and update goes installed in the user system. well IE9 should learn from all other that they have very well design auto-update system who never give user in trouble that your browser goes old. Chrome and Firefox both update themselves and say user restart to enjoy another good version. in IE6 a big problem is that updates. no one sure that they installed new version of IE6 without any hassles and update goes install without any problem because they really know or care about “you need this to install this and this for this” so they thing “why I update IE whenever I am unsure that my browser goes update and I have no problem again” so they do nothing because their work done with no problem because common person used high profile application who work even in IE6. so they do nothing.    IE6 countdown website have designed a banner for warn or force user to upgrade to next version of IE. well there is no good reason for put the banner on website some of reason are:-   Windows 7 comes with pre-installed IE8 and Vista comes with upgrade version them IE6 so that is sure that you force a user who have Windows XP [luna] and if they want to upgrade IE then they can get IE8 not version 9 because IE9 is design for Windows 7 or Vista Service pack 2. so What is the use of update when user still have a outdate version too because IE8 is old version and not have any capability of HTML5 so forcing user by using the banner have no sense. I am not know why they all listed on website put the banner on their own website. it’s good that you offer user what they want instead of giving them a outdate version of IE again. My means to give a user list of browser they can try to enhance their browser experience instead of only IE.   IE9 build upon WPF and they spent more time on using WPF in IE instead of making user experience browser.  many thing is designed wrongly in IE first thing is tabs. the tabs in chrome are bigger and easily to move and same in Firefox even not have smooth tabbing. IE have same tabbing as chrome have but leak a point that it’s too small. if you really  want to move then sometime they create a problem that they going elsewhere from the current instance of IE.   Chrome have a big buttons, tabs and menu to enhance browser experience and Firefox have a good feature that you can make them bigger or small. you can put the icon for add-ons on the toolbar for easily use but IE have no relation with customization so we never can thinking about that.   When chrome provide lot’s of extensions and a  webstore for browser application and same feature in Firefox can be seen then there is no plugin in IE. really you can see their IE addons Website where no plugin listed for web development. even in the category or tag. as a response from many blog there is new for developer that new version of IE9 developer tool. well IE9 have three new tabs a blogger tell on their blog. when I trying them I found many thing but I still unable to edit the Css from the HTML tab and no plugin I found I can get to enhance IE9 web development. something more other provide never IE9 give me like personas , customization , browser extension or any other they used to tell a small thing customization  .   IE9 still have some problem with JavaScript that when I use Firefox and chrome and logout in both then my cookie is deleted but in IE it’s not done. it’s show me that IE9 still have different from other not for good thing even some bad thing too. When I trying to read a article that is written in Hindi using Unicode font I found that they show many thing misspelled. there is three Sha in Hindi but they all goes wrong in IE. the misprint thing is not that the writing  for the articles goes wrong. it’s problem or browser to rendering a font. the Firefox and chrome not give me this problem even opera render the font in italic style by decrease the font-size but all those work perfect.   in Pwn2Own the apple’s safari  and IE9 both are hacked. this is a awesome news for whose who thing that  open-source is lose in  Security and close-source is highly-secured software. well this is not a good parameter for talking about software. it’s should depend how much application tested and used. because more testing and more use of application make them better.   I  appreciate IE to making their new version 9 and good luck for them. there is a another matter that I personally found nothing on them.

• Matching my skills with Java and Web Programming

  - by John R

  here is my main question: What is the most common way that Java is used in web development? The reason I ask: I am currently in the process of finding my first internship. Every employer has a separate set of languages, technologies and acronyms they want their candidates to know. In school I did well with Java. As a hobby and interest I have developed a handful of web pages widgets, scripts, etc. My university emphasized Java, C and theory. My hobbies emphasize HTML, PHP, JavaScript, CSS, and a little jQuery, etc. I can't learn a dozen different technologies to satisfy most prospective employers (in what is left of the summer). I think my best bet is combine my skills with Java and my interests in web development. That brings me back to my original question: What is the most common way that Java is used in web development?

• Ubuntu 14.04 liveusb boot screen graphic errors

  - by user568109

  I am trying to install Ubuntu 14.04 on my Lenovo Y500 laptop. It came preinstalled with Windows 8. I want to install it in a separate partition with a USB drive. I have tried both Unetbootin and universal usb installer. But for some reason the screen after booting is crappy. The screen goes blank after selecting try ubuntu or install. If I try with nomodeset option the screen only displays on a small strip on the top. Which again is split into three. Each seem to be identical. It is not decent enough to begin installation. The graphic card in my laptop is Nvidia GT650M, if it helps. Maybe the problem is related to that. Can anyone help in fixing this error when installing Ubuntu.

• Is imposing the same code format for all developers a good idea?

  - by Stijn Geukens

  We are considering to impose a single standard code format in our project (auto format with save actions in Eclipse). The reason is that currently there is a big difference in the code formats used by several (10) developers which makes it harder for one developer to work on the code of another developer. The same Java file sometimes uses 3 different formats. So I believe the advantage is clear (readability = productivity) but would it be a good idea to impose this? And if not, why? UPDATE We all use Eclipse and everyone is aware of the plan. There already is a code format used by most but it is not enforced since some prefer to stick to their own code format. Because of the above reasons some would prefer to enforce it.

• Find out if there is a local user logged in when logging in over ssh

  - by sebastiangeiger

  I need to run some calculations on a machine that I can only access remotely but also serves as a work station. There are many of them and I want to pick a "free" one. Free means in this case that no one is logged in locally. My first try was the who command, but for some reason it only lists "selected" users and I can't really find out how they are selected. Next try: ps aux | cut -d " " -f1 | sort | uniq: better showing a bunch of demons but also the local user that was not displayed by who. My current solution is to go in and do ps aux | grep "gnome-session" which is better but still gives me a lot of junk. Ideally I am looking for something that I can include in my ssh profile that warns me about (active) local users when I log in.

• How much C/C++ knowledge is needed for Objective-C/iPhone development?

  - by BFree

  First, a little background. I'm a .Net developer (C#) and have over 5 years experience in both web development and desktop applications. I've been wanting to look into iPhone development for some time now, but for one reason or another always got side tracked. I finally have a potential project on the horizon, and I'm now going full steam ahead learning this stuff. My question is this: I haven't done any C/C++ programming since my schooling days, I've been living in managed land ever since. How much knowledge if any is needed to be successful as an iOS developer? Obviously memory management is something that I'll have to be conscious about (although with iOS 5 there seems to be something called ARC which should make my life easier), but what else? I'm not just talking about the C API (for example, in order to get the sin of a number, I call the sin() function), that's what Google is for. I'm talking about fundamental C/C++ idioms that the average C# developer is unaware of.

• Windows Store now open to lots more developers (120 markets!)

  - by Michael B. McLaughlin

  See the post here: http://blogs.msdn.com/b/windowsstore/archive/2012/09/11/windows-store-now-open-to-all-developers.aspx . This includes individual accounts now so if you tried signing up before and got a message about it only covering company accounts, you can sign up now. Don’t forget to verify your account and setup your payment and tax information. Also, if you are an MSDN subscriber you should be able to get a code from the MSDN site that will give you a free year (saving $49 US) but you will still need to submit some form of payment (e.g. credit or debit card) for verification purposes and so that they can automatically rebill you at the end of the subscription year (unless you’ve cancelled your account for some reason, of course). Go forth and register and make awesome games and apps for me to buy and play and use!

• Nvidia Driver versions?

  - by Patrick Krenz

  I've looked all over and can't find any reason as to why or how Nvidia names their drivers. for example they have a 330.xxx/340.xxx series that are current but also a 300.xxx and i've found that they aren't always release in order by number. Here's an example on there site with version and release date 331.38 - January 13 334.16 - Feb 7 331.49 - Feb 18 I'm really confused about what driver to actually go with, a few different series versions seem to work adequately and I just want to have an understanding of it and what the best option to work from would be. I really appreciate any information

• Why is facebook cache buggy?

  - by IAdapter

  I just started using facebook and I see that many times when I add something to my profile and visit it later its not there. I bet the reason is that the page is cached and not updated very often. Is this on purpose or is it a bug? P.S. For example I added the music I like and later I see that I did not add it, but next day when I visit again its there. I saw it in two web-browsers, so its a facebook bug. Does it has something to do with scalability?

• Dealing with frustration when things don't work.

  - by John Isaacks

  You ever try to implement something simple but for some strange reason it doesn't work. So you try a possible solution but then something else doesn't work. You keep trying different workarounds but every time something different isn't working. Every time you get one step closer you also get one (or more) step farther from solving this problem and its now been 3 hours when this should have taken you 10 minutes. And it still isn't solved. There is no one in your company who can help, and you are about to put your fist through your screen. At this point you are so frustrated you can no longer think about the problem clearly. What should you do at this point? Or what can you do to avoid reaching this point?

• What is Perl's relation to hackers? [closed]

  - by K.Steff

  I know Perl is a language revered by many hackers (as in hacker vs cracker) and respected by many good programmers for its expressiveness. I also realize it is useful to know and it's very handy at generalizing common Unix tasks (Unix here includes Linux and Cygwin). I also know that being a good hacker probably means you're a good programmer in general (references on this one are sparse around the web, but about everything Paul Graham has ever written seems approving of this statement to me). So my question is whether there is a reason that attracts hackers to Perl in particular? Will learing Perl improve my general programming, problem-solving and hacking skills if done properly? Does it present unique tools that are more useful to a hacker?

• Monitor not turning off when screen saver is on

  I installed Ubuntu for the first time 3 weeks ago and I really love it. I have Ubuntu 12.04. My only problem is that when screen saver is on, it just shows blank screen, and not turning off the monitor, so my monitor is always on. I have Samsung E2220 - 22". I looked over the web and I found this command: sudo xset dpms force off This command shuts down my screen so I don't see a reason why the screen saver can't shut it down. Thanks a lot! Elad

• Recommendations for a network of student-related content

  - by Javier Marín

  I am running a network of websites with notes, homeworks, essays, etc. where users share their own content. I'm having real trouble with the latest Google updates (penguin, panda, etc) because the content is mainly poor-quality and with the same topic. For that reason, I want to create more websites and have more probabilites to appear in the SERPs. My question is: does Google analyzes related websites in order to exclude it from the results? I've think about distribute the websites around the world, in different hostings, but I'm afraid that Google would link it by their analytics, webmaster tools or adsense account, is that possible? What other recommendations do you have?

  I'm trying to integrate Amazon GameCircle and I have been able to successfully initialize GameCircle in my app, but the problem is when I click on the button that displays achievements, the GameCircle achievement list comes up but it says "You have unlocked 0 of 0 achievements". Same happens with leaderboards i.e there are no leaderboards for this app. I have created a Leaderboard and a few achievements on the online developer portal for Amazon but they don't show for some reason. Can someone help me with this. Any links/resources that help with integrating GameCircle will be appreciated. Thanks.
