  • What is the preferred/recommend way of running two version of ubuntu side by side

    - by GreyGeek
    I am running 14.04, but I need to run some corporate software/scripts that have been specifically designed for 12.04. I am aware of virtual box/vmware for full virtualization but I am looking for something more lightweight (on my windows machine both come at a significant cost in battery life) closer to os virtualization level. Ideally, I would like something like windows 7/8 compatibility mode: the ability to run a program as if I were on 12.04. Does Ubuntu/Linux have such mechanism? What is the preferred way of running programs/scripts designed for an older version of Ubuntu?

  • When Agile goes wrong

    - by Chepech
    Im writing an Agile course for some of the new guys we are on-boarding recently and I want to add a cautionary tale so they understand that Agile is not meant for all projects. My problem is that because of the nature of the projects I work in Agile has worked pretty well so far so I can't honestly point out what can go wrong and why when you use it in the wrong kind of project. Does anyone have a good real life example of a project where an Agile approach (e.g. Scurm) simply didn't worked out?

  • How to start working in a team on a project? [closed]

    - by Adio
    Ok, for the first time in my life I am going to work in a team. The problem is that all the team members including me are junior developers and for all of us this is the first time we are working in a team. The problem is that we do not know how to start the project. We know a little about scrum and agile development, we have our user stories in place and our created project - which does not have even one piece of code - and now we are stuck and don't know how and what to do? All scrum books talk about scrum development but lack of the details like how to start. How my team will know what object I am using? How we will push the first piece of code and what it will be? Any help will be great. Books, articles, advice, or anything.

  • What does ^+Z do to a process

    - by Kifsif
    In command line I wrote: michael@ubuntu:~$ firefox Firefox launched. Command prompt ($) disappeared. Then I pressed ^+z. The result was: [1]+ Stopped firefox Well, Firefox really stopped. It did not react anyhow. So, I could not close it by pressing the cross of the window. By the way, the menu items 'Tools', and 'Help' somehow showed some signs of life. They showed drop-down lists, but nothing more (no reaction to inner menu items). Well, I could not end Firefox through System Monitor. Could you comment on this case: what happened after pressing ^+z?

  • How do I remove Skype 4.3 from Ubuntu 14.04 LTS (32-bit)

    - by Lucas W
    I installed Skype on my nephew's new Ubuntu 14.04 LTS machine, and now we've decided to remove it. But I'm not able to locate it in my Installed programs section of Ubuntu Software Center. I'm able to call it up by opening the debian package, Software Center opens it up, but where I would normally see the "Remove" button, I have a "Reinstall" button. For the life of me, I can't figure out how to uninstall Skype. Any suggestions? In case you're wondering I used the version of Skype designed for 12.xx, as there was no option available for Ubuntu 14.xx.

  • How to deal with OOP design problems in interviews?

    - by haps10
    This is a question where I seek guidance from fellow/senior developers to get into my dream company - it's a pioneer in OOP and Agile. I've already failed once to clear an interview. One part I feel most challenging is to come up with a proper Object Oriented design(classes, interfaces, methods, interactions etc.) in a very short time for certain situations like Pacman, Game Of Life and so on. As the problems are unprecedented ones - my approach is mostly to try different things and then make decisions - which they feel is not clear and not what they expect from a developer with 5+ years of experience. I've already studied a few books on patterns, OOP - it didn't help me much and I think it'll take a bit more than that. Could some one please guide on what specifically shall I practice so that I can do better at design problems as above. I want to refine my approach and have a better thought process.

  • Cannot get laptop wifi to work in ubuntu 12.4

    - by Coda
    Hi i have a Toshiba Satellite L645D-S4106 laptop and i recently installed ubuntu 12.4 on it and i cannot get the wifi to connect for the life of me. When i tried ubuntu out before installing it, the wifi worked while windows was still installed on it. Then i installed ubuntu and now there is no wifi. I can't even flip the wifi network switch to the on position. I installed the driver from realtek for the linux driver and still nothing. Doing rfkill list all shows soft blocked: no and hard blocked: yes. Can anyone help me :p haha very frusterating. It probably is something very dumb. Thanks

  • Found a better solution to a problem at work - should I deter from posting the code snippet online?

    - by Calmarius
    I think most of us, programmers, used Stack Overflow to solve every day problems: looked for an efficient algorithm to do something. Now imagine a situation: you have a problem to solve. Googled a bit, found a StackOverflow question but you are not really satisfied with the answers so far. So you have to do your own research: you need to do it because you want it in the company's app. Eventually after some hours you have found the better solution. You're happy, you added it to the company's code base, then you want to submit your answer with a code snippet (just several lines) to the question you've found before to help others too. But wait: the company's software is closed source, and you worked on it on the clock. So does this mean I shouldn't post the answer neither at work nor at home to that question in the rest of my life, because I solved it at work, and the company owns that piece of code?

  • Diminishing Returns - When is it Time to Take Your Website Live?

    Being a perfectionist is not always the best way to be. Especially in a world where being first to market isn't the worst thing ever. Like many things in life, deciding when to take your new website live is a fine balancing act. The sooner you can start building up a readership or client base, the better; but you risk serious damage to your site's reputation if its functional and technical performance is below par. So when is the right time?

  • Setting Up Your SQL Server Agent Correctly

    It is important to set up SQL Server Agent Security on the principles of 'executing with minimum privileges’, and ensure that errors are properly logged and alerts are set up for a comprehensive range of errors. SQL Server Agent allows fine-grained control of every job step that should allow tasks to be run entirely safely even if they occasionally need special privileges. Can 41,000 DBAs really be wrong?

  • How realistic is it to find remote jobs? [on hold]

    - by user3728220
    I just started teaching myself Python and so far I'm really enjoying it. One of my goals in life is to find a job that I can do remotely from anywhere in the world (that has reliable internet). I know that for some programming career paths this would be impossible to do, so I'm looking for comments or advice about the best way to achieve this. Whether there's certain types of companies or industries to look for, any particular languages that would be best-suited for this, anything else I should know, etc. Thanks!

  • How many hours do you spend programming outside of work if you are married (with children) [closed]

    - by eterps
    I recently attended a conference and met some insanely talented developers with mile-long lists of accomplishments. One puzzling thing I noticed about many of these wildly successful people is that a lot of their output (books, blogs, games, mobile apps) are done as hobby projects outside of their normal jobs. Not only this, but most of them were married, and some even with children. I'm absolutely baffled by this. My question is targeted to folks that are married, working full time, and also spend time outside of work on hobby projects or extra programming. The question is: How many hours do you put in programming outside of your normal job, and how do you balance it with your family life?

  • Kworker consuming %100 CPU

    - by yusuf
    I have a process, named kworker which is continuously consuming 100% of the CPU's computing capacity. I have tried several possible solutions over a period of 3 months, but to no avail. I even got to upgrade to u + 1 (Ubuntu 12.10 Quantal Quetzal), but my effort was, again, fruitless. I desperately need some help, because, as is, this process is draining my computer's battery so fast, that makes linux usage a disappointing experience. It is noteworthy, that I do not have any such issues when I use windows, which results in twice as much battery life.

  • How do I convert an INT into HH:mm:ss using SSRS 2005

    - by user293249
    Ok I need to display total talk time of an agent that is coming into SRSS 2005 from SQL 2005 as an INT. For the life of me I cannot figure out what combination of expression editing or format editing I need to use. For the detail portion I can use: =DATEADD("s", SUM(Fields!Talk_Time.Value), CDate("00:00")) And it will return: 1/1/0001 12:00:14 AM Now I can use =LEFT(DATEADD("s", SUM(Fields!Talk_Time.Value), CDate("00:00")),8) Which will return: 12:00:14 But really what I need is: 00:00:14 Please help!
