  • How to report a crash bug with nothing on screen

    - by winniemiel05
    I would like to report an installation bug, but I can't launch ubuntu-bug : On my tablet (LDLC Janus, an Intel based tablet without OS installed by default), I have a problem when I install Ubuntu 11.04 or 11.10. Once the installation is finished, when I reboot, there is ABSOLUTELY nothing on screen, but Ubuntu boot correctly anyway : I choosed auto-login mode and I can hear the login sound. Even if I Ctrl+Alt+F1 or F2... there is nothing. But the livecd works fine (even touch screen even if without multi touch). I tried to install 10.10 it works, but as soon as I upgrade the same problem occure. i installed Fedora 15 and then Fedora 16 (because of other problems) and no problems with them. I would like to report this bug on launchpad but I don't know how to do to give devs logs files and other useful files which could help debug. Thanks a lot for your answer, I would really prefer using my tablet with Ubuntu (I miss U1, USC, Unity)

  • Like camping on the moon

    - by Marc Schluper
    No Silverlight today. I made a mistake. I created an application to upload a file and store it encrypted on a server. But I forgot to check on what machine it needed to be deployed. Yesterday I heard it was on an old ASP.NET 1.1 machine. Oops. Oh well, how hard can it be to change this simple application? Answer: much harder than I thought. Today I took out: Encryption using X509 Certificates Master Pages Compression Using statements Generic lists Upload control ASP.NET Membership All via a key hole to access a virtual machine. It has its charm, though, doing primitive things. Like camping on the moon.

  • How to enable 3D acceleration under VMware workstation 8?

    - by Yan Zhou
    I saw there are similar questions, but I don't think they answer exactly my questions. Did anyone managed to get 3D acceleration work under VMWare workstation 8? I have VMware 8.01 installed on Ubuntu 11.10. The guest I am trying is also Ubuntu 11.10. I manually installed vmware-tools and it went well, except the X-config part was skipped as it said the distribution driver is used. The guest runs well but it seems fall back to 2D mode. Does any one has any idea how to enable 3D acceleration under VMWare workstaion with Linux guest?

  • How to introduce versioning for questions on Stack*? [closed]

    - by András Szepesházi
    What today is the best answer for any given question, yesterday was not available and tomorrow will be obsolete. Especially when we're talking about software development. Here is an example for you (there must be thousands, this one is absolutely imaginary): Q: What is the best way to implement autocomplete in javascript? A: (2000) Whut? A: (2007) Write a custom ajax function, display the results after processing A: (2011) Use this plugin: http://jqueryui.com/demos/autocomplete/ (nono, I'm not a jQuery affiliate, actually I prefer MooTools) What would be your recommendation to introduce versioning for Stack Exchange questions and answers? Is there a need at all for that?

  • Why there are many guest accounts?

    - by Radu Radeanu
    After I saw this answer, I realized that there are many guest accounts on my system: grep guest /etc/passwd guest-jzXeRx:x:117:127:Guest,,,:/tmp/guest-jzXeRx:/bin/false guest-l5dAPU:x:118:128:Guest,,,:/tmp/guest-l5dAPU:/bin/false guest-FdSAkw:x:119:129:Guest,,,:/tmp/guest-FdSAkw:/bin/false guest-eBU0cU:x:121:131:Guest,,,:/tmp/guest-eBU0cU:/bin/false Moreover, in this moment there is nobody logged as guest, but if somebody will login as guest, a new guest account is created - why, since there are already other guest accounts? After the new guest will log out, his account will be deleted. But why the other guest accounts remain? For what use/purpose? It doesn't mind me at all this guest account, but I want to know if it is okay to delete them manually.

  • Backend devs put down by user stories

    - by Szili
    I planned to slice in backend development into to the user stories vertically. But a backend guy on our team started to complain that this makes their work invisible. My answer was that at the sprint planning and review meetings we discuss backend tasks in front of stakeholders so it makes it visible, and maintaining a high quality during the project will result a slower startin pace than other teams, but we will have a stable velocity during the project. And velocity is highly visible to stakeholders. He still insist having stories like: "As a developer I need to have a domain layer so I can encapsulate business logic." How can I solve the issue before it pollutes the team? The root of the issue is that our management systematically consider backend work as invisible and call backed devs miners, or other pejorative terms.

  • Follow-up Answers for my Australia Classes

    - by Kalen Delaney
    I was out of the country for the last two weeks of March, delivering classes in Brisbane and Sydney, which were organized by WardyIT . It was a great visit and there were 24 terrific students! As is sometimes (perhaps often?) the case, there were questions posed that I couldn’t answer during class, so here are a couple of follow-up answers. 1. I brought up the fact that SQLS 2012 generates a warning message when there are ‘too many’ Virtual Log Files (VLFs) in a database. (It turns out the message...(read more)

  • How to impove Ubuntu performance on netbook

    - by Alexey Shytikov
    Most recent Ubuntu 12.04 seems to be quite nice and Unity (3D/2D) works fine for me, however not on my old Acer Aspire One any more. There was a times, when I switched from Windows XP to Ubuntu and was happy about system looks, effects and speed... now I attend to think that XP was really great comparing with 12.04. I have found similar questions here but no reasonable answer: how to lower CPU usage for Unity (3D/2D) and memory consumption for Ubuntu 12.04. With new interface I could not find how to disable background services... It's Linux, it's should be the way to optimize without buying new PC... Please share your recipe!

  • SQL SERVER – Beginning New Weekly Series – Memory Lane – #001

    - by pinaldave
    I am introducing a new series today.  This series is called “Memory Lane.”  From the last six years and 2,300 articles, there are fantastic articles I keep revisiting.  Sometimes when I read old blog posts I think I should have included something or added a bit more to the topic.  But for many articles, I still feel they are fantastic (even after six years) and could be read again and again. I have also found that after six years of blogging, readers will write to me and say “Pinal, why don’t you write about X, Y or Z.”  The answer is: I already did!  It is here on the blog, or in the comments, or possibly in one of my books.  The solution has always been there, it is simply a matter of finding it and presenting it again.  That is why I have created Memory Lane.  I will be listing the best articles from the same week of the past six years.  You will find plenty of reading material every Saturday from articles of SQLAuthority past. Here is the list of curetted articles of SQLAuthority.com across all these years. Instead of just listing all the articles I have selected a few of my most favorite articles and have listed them here with additional notes below it. Let me know which one of the following is your favorite article from memory lane. 2006 Query to Display Foreign Key Relationships and Name of the Constraint for Each Table in Database My blogging journey began with this blog post. As many of you know my journey began with creating a repository of my scripts. This was very first script which I had written to find out foreign key relationship and constraints. The same query was updated later on using the new SYS schema modification in SQL Server. Version 1: Using sys.schema Version 2: Using sys.schema and additional columns 2007 Milestone Posts – 1 Year (365 blogs) and 1 Million Views When I reached 1st week of Nov in 2007 SQLAuthority.com blog had around 365 blog posts and 1 Million Views. I was not obsessed with the statistics before but this was indeed an interesting moment for me as I was blogging for myself and did not realize that so many people are reading my blog. In year 2006 there were not many bloggers so blogging was new to me as well. I was learning it as I go. 2008 Stored Procedure WITH ENCRYPTION and Execution Plan If you have stored procedure and its code is encrypted when you execute it what will be displayed in the execution plan. There are two kinds of execution plans 1) Estimated and 2) Actual. It will be indeed interesting to know what is displayed in both the cases when Stored Procedure is encrypted. What is your guess? Now go ahead and click on here and figure out your answer. If the user is not able to login into SQL Server due to any error or issues there were two different blog post addresses the same issue here and here. 2009 It seems like Nov is the month of SQLPASS month. In 2009 on the same week I was in USA attending SQLPASS event. I had a fantastic experience attending the event. Here are the blog posts covering the subject Day 1, Day 2, Day 3, Day 4 2010 Finding the last backup time for all the databases This little script is very powerful and instantly gives details when was the last time your database backup performed. If you are reading this blog post – I say just go ahead and check if everything is alright on your server and you have all the necessary latest backup. It is better to be safe than sorrow. Version 1: Above script was improved to get more details about the database Version 2: This version of the script will include pretty much have all the backup related information in a single script. Do not miss to save it for future use. Are you a Database Administrator or a Database Developer? Three years ago I created a very small survey and the results which I have received are very interesting. The question was asking what is the profile of the visitor of that blog post and I noticed that DBA and Developers have balanced with little inclination towards Developers. Have you voted so far? If not, go ahead! 2011 New Book Released – SQL Server Interview Questions And Answers One year ago, on November 3, 2011 I published my book SQL Server Interview Questions and Answers.  The book has a lot of great reviews, and we have even received emails telling us this book was a life changer because it helped get them a great new job.  I don’t think anyone can get a job just from my book.  It was the individual who studied hard and took it seriously, and was determined to learn something new.  The book might have helped guide them and show them the topics to study, but they spent their own energy on it.  It was their own skills that helped them pass the exam. So, in this very first installment, I would like to thank the readers for accepting our book, for giving it great reviews and for using it and sharing it.  Our goal in writing this book was to help others, and it seems like we succeeded.

  • What are some valuable conferences for game developers?

    - by Tommy
    Lately I was thinking of visiting a Game Developer Conference and so I search the Internet, but I didn't find a thorough list of available Conferences. Now I know some of them, like the GDC in San Francisco but I was wondering, what other Game Developer Conferences are out there. So my question is: What Game Dev Conferences do you know, that are valuable for Game Developers and Game Designers? Have you visited one of these Conferences yourself? Is there a skill level needed to appreciate such a Conference? I am aware, that there is no "true" answer to this question, but I think, that an overview over existing Conferences could be usefull for all levels of game developers.

  • Java - learning / migrating fast

    - by Yippie-Kai-Yay
    This is not one of those questions like "How do I learn Java extremely fast, I know nothing about programming, but I heard Java is cool, yo". I have an interview for a Java Software Developer in a couple of weeks and the thing is that I think that I know C++ really good and I am somewhat good at C# (like, here I can probably answer on a lot of questions related to these languages), but I have almost zero experience with Java. I have a lot of projects written in both languages, I participiated in several open-source projects (mostly C++, though). Now, what should I do (in your opinion) to prepare myself for this Java interview. I guess migrating from C# to Java should be kind of fast, especially when you know a lot about programming in global, patterns, modern techniques and have a lot of practical experience behind you. But still two weeks is obviously not enough to get Java in-depth - so what should I focus on to have the best chances to pass the interview? Thank you.

  • Setting environment variables when executing Eclipse via Unity launcher icon

    - by Nullptr
    My question is a followup for the following: How to pin Eclipse to the Unity launcher? I created Eclipse's icon to the Unity launcher based on the selected answer at the above link. However, when I launch Eclipse via this icon, the environment variables are not properly set. I need to call . /opt/intel/bin/compilervars.sh intel64 to use Intel compiler tools in Eclipse. However, launching via the icon can't do it. Of course, running manually Eclipse on the terminal is okay. I tried to place . /opt/intel/bin/compilervars.sh intel64 on several places such as /etc/profile and /etc/bash.bashrc. But, still not working. Where is the best and correct place to call such environment setup?

  • Adding a Wine (.exe) file to open/play files in Thunar's 'Custom Actions'

    - by cipricus
    What is the line parameter in Thunar's "custom actions" that would play a music directory in a Wine (.exe) program? I want to put Foobar2000 (and possibly other such applications) in Thunar's Custom Actions (actions that can be added/edited to be used in the context menu to play music folder's content). If I put no command parameter at the end of path, the player opens but there is no play and no files in the play list. If I add any of the listed parameters I get the error unknown commandline parameter: /path.to.file (Giving an answer to this question depends on knowing the CLI command that would have to be added into Thunar - so please look at this question too)

  • Best practices for web page styling with CSS?

    - by adifire
    I have a website to design. I have information on how the page should look and interact. The problem is I'm not good in front-end design, and have put many many hours to get the hang of the stuff. Currently, i am getting the CSS from sample sites in github and use them to style my site, which seems to be Not a ethical way. Question: how do you style webpages? Are there some really good tools? I would be deeply appreciated if a detailed answer will bee provided or link to wiki will work as well.

  • Web Frameworks caring about persistence?

    - by Mik378
    I have noticed that Play! Framework encompasses persistence strategy (like JPA etc...) Why would a web framework care about persistence ?! Indeed, this would be the job of the server-sides components (like EJB etc...), wouldn't this? Otherwise, client would be too coupled with server's business logic. UPDATE: One answer would be : it's more likely used for simple application including itself the whole business logics. However, for large applications with well-designed layers(services, domain, DAO's etc..), persistence is not recommended within web client layer since there would be several different web(or not) clients.

  • 13.04 Gnome - removing icons from lower panel

    - by Mikey
    I use the stripped down Gnome UI for 13.04 (Gnome-no effects) and on the bottom there is a panel where you can put icons for app launchers, by dragging them from applications menu. This is probably a really dumb question, but I can't figure out how to REMOVE a launcher icon from that panel once I put there! How is this done? Note - I saw another answer that said click alt-super and right click on top panel - I clicked remove launcher and now my top Application and Places menus are gone! How do I get them back - all screwed up now.

  • Useful code paste site tools

    I know there are site tools to check if your webpage is alive, has compression, etc but lets not get into that. What are useful sites to paste code in and to share links of? The three i know are http://codepad.org/ shows source and runs code online http://www.pastie.org/ share source with syntax highlighting http://jsfiddle.net/ great for JS help or for the occasional test. What else do you know of? One answer per question. I'll let lints and validators slide since you do paste code into them.

  • Next in Concurrency

    - by Jatin
    For past year I have been working a lot on concurrency in Java and have build and worked on many concurrent packages. So in terms of development in the concurrent world, I am quite confident. Further I am very much interested to learn and understand more about concurrent programming. But I am unable to answer myself what next? What extra should I learn or work on to inherit more skills related to Multi-core processing. If there is any nice book (read and enjoyed 'concurrency in practice' and 'concurrent programming in java') or resource's related to Multi-core processing so that I can go to the next level?
