  • Is ignoring clients data during an automatic upgrading acceptable?

    - by A competent translator
    I recently faced a deletion of my calendar and notes data inside a third party application ( Horde ) on my online space. When I told the web hosting provider they replied that they were doing an upgrade to system software (!!) and client third party applications are not within their reach or backup policy. They don't even have a backup of my data. Is this practice acceptable from a web hosting provider, even for an individual clients ? I know that backing up my data is my responsibility but I anticipated that backup copies done by the host would be available when needed.

  • Lost power during upgrade, how do I recover?

    - by Ryan McClure
    I was attempting to update my 11.10 install to 12.04beta. During the install step, I accidentally lost power to my laptop (the power cable came unplugged) and it shut down. Whenever I go to boot now, I can select my install via Grub and it loads up to where the sign-in should happen, but I get a display that looks like what you see as soon as you shut down. It looks like it locks after checking for the battery. Is there anyway, with or without Live media, to restore my machine's install/update to 12.04 but still keep my settings/applications/files?

  • Conky dropping shadow when invoked at startup

    - by boywithaxe
    I read this thread but it doesn't really address my issue. The problem that I have is that whenever I log in, conky starts up, as set up in Startup Applications, but the instance it runs is dropping shadow and is above every other window, showing the wallpaper beneath it. This can be easily fixed by relaunching conky, but that defeats the purpose of having it start up at login. Also, running conky at any point manually after logging does not cause this. Any suggestions? I rewrote the script and played about with Compiz, but it still keeps happening.

  • Why would I want to use CRaSH?

    - by Adam Tannon
    Justed stumbled across CRaSH and although it looks mighty interesting, I'm wondering why a Java developer should invest time & energy into learning (yet another) shell language. What sort of standard- and cool-applications can CRaSH be used for? Is this like a Groovy-version of Jython? I guess, when the dust settles, I'm looking for CRaSH's "wow" factors. I'm sure they're there, but after spending ~20 minutes perusing the documentation I'm just not seeing them. Thanks in advance!

  • How to write loosely coupled classes in node.js

    - by lortabac
    I am trying to understand how to design node.js applications, but it seems there is something I can't grasp about asynchronous programming. Let's say my application needs to access a database. In a synchronous environment I would implement a data access class with a read() method, returning an associative array. In node.js, because code is executed asynchronously, this method can't return a value, so, after execution, it will have to "do" something as a side effect. It will then contain at least 1 line of extraneous code which has nothing to do with data access. Multiply this for all methods and all classes and you will very soon have an unmanageable "code soup". What is the proper way to handle this problem? Am I approaching it the wrong way?

  • Different behavior when launched from terminal instead of Unity launcher

    - by dgkontopoulos
    I have written two Perl/Gtk programs. When launched from the dash menu, they run just fine. However, if I try to launch them from terminal using the very same command found in their .desktop files, their Unity launcher will be blurry and will remain inactive when clicked, if I keep it in the Unity bar. The problem is solved if the Exec part of the desktop file is replaced with perl path_to_script However, that leads to other problems, including a lintian warning and forcing all Perl GUI applications running from terminal to adopt the same launcher. This issue is quite annoying since one of the programs relies on a different (Python) program in order to be launched and this results in having a blurry and inactive launcher.

  • Changing Workspaces changes active window

    - by puk
    I have a dual monitor setup, but I am sure it's the same with a single monitor. If I have two applications open, one is vim, the other is google chrome. Lets say the focus is on vim. If I switch to another workspace (ie. alt3) then switch back to that workspace (ie. alt1) now the focus is on google chrome. This process toggles indefinitely so long as I don't transition too quickly. Is there any way to prevent/disable this?

  • What options should I consider for a modern Web/Mobile development stack? [on hold]

    - by jimmy_terra
    I'm a long time server side dev who has been tasked with building a bleeding edge web UI (go figure), so apologies for the very broad nature of the question. What are the best modern libraries, tools, languages and patterns for building a dynamic web application that will run seamlessly on mobiles also? My requirements are that it must be dynamic (push updates), support automated testing, and should allow 'componentization' (a team of devs will be working on this). What should I check out and why? I will start off with some of the things I'm looking at already: Front-end HTML5 CSS3 JavaScript AngularJs Testing Karma Testem Jasmine Patterns Single Page Applications

  • How can an application (like Firefox) be forced to use a certain network interface?

    - by Lekensteyn
    I've two interfaces: eth0 and wlan0 on a notebook. Possible use cases: eth0 grants me Internet access, and wlan0 is currently connected to a router which does not have Internet-connectivity. For development purposes, I need to connect to the wlan0 by default, but use eth0 for surfing eth0 and wlan0 are both connected to the Internet. For a torrent application, eth0 should be used for speed, but for portability of the notebook, SSH should have a connection over wlan0 eth0 is a wire connection, wlan0 is a wireless one. Sensible data should be transferred over eth0, but other traffic can go over wlan0 as well. Is there a way to force applications (like nc.traditional or firefox) to use a certain network interface? A wrapper like example-wrapper eth0 program is fine too if such program exist. It would be nice if it could configured within Firefox (in runtime). I'd like to avoid IPTables solutions if possible.

  • Windows 8 for productivity?

    - by Charles Young
    At long last I’ve started using Windows 8.  I boot from a VHD on which I have installed Office, Visio, Visual Studio, SQL Server, etc.  For a week, now, I’ve been happily writing code and documents and using Visio and PowerPoint.  I am, very much, a ‘productivity’ user rather than a content consumer.   I spend my days flitting between countless windows and browser tabs displayed across dual monitors.  I need to access a lot of different functionality and information in as fluid a fashion as possible. With that in mind, and like so many others, I was worried about Windows 8.  The Metro interface is primarily about content consumption on touch-enabled screens, and not really geared for people like me sitting in front of an 8-core non-touch laptop and an additional Samsung monitor.  I still use a mouse, not my finger.  And I create more than I consume. Clearly, Windows 8 won’t be viable for people like me unless Metro keeps out of my hair when using productivity and development tools.  With this in mind, I had long expected Microsoft to provide some mechanism for switching Metro off.  There was a registry hack in last year’s Developer Preview, but this capability has been removed.   That’s brave.  So, how have things worked out so far? Well, I am really quite surprised.  When I played with the Developer Preview last year, it was clear that Metro was unfinished and didn’t play well enough with the desktop.  Obviously I expected things to improve, but the context switching from desktop to full-screen seemed a heavy burden to place on users.  That sense of abrupt change hasn’t entirely gone away (how could it), but after a few days, I can’t say that I find it burdensome or irritating.   I’ve got used very quickly to ‘gesturing’ with my mouse at the bottom or top right corners of the screen to move between applications, using the Windows key to toggle the Start screen and generally finding my way around.   I am surprised at how effective the Start screen is, given the rather basic grouping features it provides.  Of course, I had to take control of it and sort things the way I want.  If anything, though, the Start screen provides a better navigation and application launcher tool than the old Start menu. What I didn’t expect was the way that Metro enhances the productivity story.  As I write this, I’ve got my desktop open with a maximised Word window.  However, the desktop extends only across about 85% of the width of my screen.  On the left hand side, I have a column that displays the new Metro email client.  This is currently showing me a list of emails for my main work account.  I can flip easily between different accounts and read my email within that same column.  As I work on documents, I want to be able to monitor my inbox with a quick glance. The desktop, of course, has its own snap feature.  I could run the desktop full screen and bring up Outlook and Word side by side.  However, this doesn’t begin to approach the convenience of snapping the Metro email client.  Consider that when I snap a window on the desktop, it initially takes up 50% of the screen.  Outlook doesn’t really know anything about snap, and doesn’t adjust to make effective use of the limited screen estate.  Even at 50% screen width, it is difficult to use, so forget about trying to use it in a Metro fashion. In any case, I am left with the prospect of having to manually adjust everything to view my email effectively alongside Word.  Worse, there is nothing stopping another window from overlapping and obscuring my email.  It becomes a struggle to keep sight of email as it arrives.  Of course, there is always ‘toast’ to notify me when things arrive, but if Outlook is obscured, this just feels intrusive. The beauty of the Metro snap feature is that my email reader now exists outside of my desktop.   The Metro app has been crafted to work well in the fixed width column as well as in full-screen.  It cannot be obscured by overlapping windows.  I still get notifications if I wish.  More importantly, it is clear that careful attention has been given to how things work when moving between applications when ‘snapped’.  If I decide, say to flick over to the Metro newsreader to catch up with current affairs, my desktop, rather than my email client, obligingly makes way for the reader.  With a simple gesture and click, or alternatively by pressing Windows-Tab, my desktop reappears. Another pleasant surprise is the way Windows 8 handles dual monitors.  It’s not just the fact that both screens now display the desktop task bar.  It’s that I can so easily move between Metro and the desktop on either screen.  I can only have Metro on one screen at a time which makes entire sense given the ‘full-screen’ nature of Metro apps.  Using dual monitors feels smoother and easier than previous versions of Windows. Overall then, I’m enjoying the Windows 8 improvements.  Strangely, for all the hype (“Windows reimagined”, etc.), my perception as a ‘productivity’ user is more one of evolution than revolution.  It all feels very familiar, but just better.

  • C# on ubuntu 12.04

    - by Deus Deceit
    Is C# a good choice for ubuntu programming? E.g unity, or applications that will run on ubuntu? Am I doing good wanting to learn C# when I'm determined to stick with ubuntu and develop on it or for it? If not, can you give me reasons why? And which languages would be better than c# for ubuntu development? I already know c, c++, java(basics), php, mysql, python(basics). I like to learn new stuff, but stuff that worth my time. Does C# worth my time? If c# worth my time, here's what I have done and what I need: I installed all mono packages I could find on the ubuntu standard repositories. Now I want a good tutorial to get me started. I'm a complete noob with c# so a basic tutorial and how to compile run under ubuntu 12.04 would be great.

  • Des failles découvertes dans les formats d'archivage, permettant dissimulation et propagation de cod

    Des failles découvertes dans les formats d'archivage, permettant dissimulation et propagation de codes malveillants La semaine dernière, lors de la Black Hat (l'évènement mondial en terme de sécurité informatique, qui a lieu plusieurs fois par an, cette édition s'est déroulée à Barcelone), des chercheurs ont exposé leurs résultats à propos d'une étude concernant les formats d'archivage populaires. Tomislav Pericin, fondateur du projet de protection de programmes RLPack, a découvert comment y cacher des programmes malins indétectables par la majorité des antivirus. Il assure cependant que la majorité des vendeurs d'antivirus ont récemment mis à jour leurs applications afin de détecter les formats d'archive compromis, comme ".ra...

  • Broadcasting webinars to and from Ubuntu

    - by Chris Wilson
    I've recently attended an online workshop using Citrix GoToWebinar, a service that allows someone to broadcast their desktop and audio out to all members connected to the presentation as well as receive audio and screencasts from those attendees , and the experience was unbelievable, and I was wondering if there was any such service/software available on Ubuntu. Points to consider include, but are not limited to: Web services or local applications. Free (as in beer) or paid. Free (as in speech) or proprietary. Ease of use Ease of setup Any other point that anyone can thing of

  • Use Adwaita Dark for Libre Office and possibly other apps too?

    - by Relik
    I would like to know how to force some apps to use the Adwaita dark theme. I noticed by default that the movie player and photo viewer apps in gnome shell use Adwaita Dark while most other apps use the Light variant. I would really like to set Libre Office to use Dark instead of Light. How would I go about doing this? I found the site below, but the instructions seem a bit outdated and they do not work for GTK3. http://urukrama.wordpress.com/2008/07/13/setting-a-custom-gtk-theme-for-specific-applications/

  • Chromium web-app creation doesn't work in 12.10?

    - by speter
    If you create an application of a website in Chromium and choose "desktop", a .desktop file is created. In 12.04, you were able to move it to ~/,local/share/applications/ and then start it from the Dash or the launcher. In my fresh 12.10 installation, this doesn't work anymore. I think the line that is misinterpreted is Exec=/usr/bin/chromium-browser --app=http://buymeapie.com/. If you try to run it from a terminal, you get the following result: 20:32 ~ speter Exec=/usr/bin/chromium-browser --app=http://buymeapie.com/ bash: --app=http://buymeapie.com/: Datei oder Verzeichnis nicht gefunden (English: "File or directory not found"). Can anyone explain or knows a workaround?

  • Entry level developer career advice [closed]

    - by Evan
    I just got done with college and I have a full time job with a large software company that I have been an intern at for over a year. As an intern I was on the web team doing lots of architecture and developing UI in ExtJS and some Java backend experience. Now as a full time employee I am mainly doing ExtJS applications, which I enjoy a lot, and I want to stay in the web development field, but: Am I limiting my career options with just doing ExtJS stuff? Will experience in ExtJS help or hinder my programming skills? Will I be looked down upon because I'm only gaining experienced with ExtJS?

  • Welcome to our Friday tips series!

    - by Chris Kawalek
    Today we're starting a brand new blog series. For your Friday afternoon reading, we'll be posting a technical tip or question and answer on a technical topic. We'll start by introducing ideas on our own, but we'd really like it if you were involved and asked us questions via Twitter! Tag your tweet with #AskOracleVirtualization and we'll consider your question for the blog. Today's tip is on Storage and Oracle Virtual Desktop Infrastructure: Question: I run Oracle Virtual Desktop 3.4.1 on Solaris and use a local ZFS storage pool.  How should I configure my ZFS ARC cache?  Answer by John Renko, Consulting Developer, Oracle: Oracle recommends about 5G of ARC cache per template in use to achieve up to a 90% disk read offload. Set your ARC min=max to reserve the maximum amount of your remaining memory for your running VMs. In /etc/system: set zfs:zfs_arc_min = 5368709120 set zfs:zfs_arc_max = 5368709120 The amount you need to reserve will depend on your template but this has proven to be a great start for a typical windows 7 VM running productivity applications.

  • A roadmap to learn PHP efficiently

    - by Goma
    I have been always confused when I want to start learning PHP. I got afraid of learning any bad habbits or things that could lead to unsecure applications. If you can help and hope you can, I would like to ask you experts in PHP to help me and put a roadmap for me from the beginning. It would be better if it is a series of books so when I finish a book I go to the next or a series of videos or whatever. No worries about how much the books may cost, most importantly that I will learn the right things. Thanks.

  • How do you verify that your prototype/application meets the requirements?

    - by Roflcoptr
    Recently I wrote an small prototype that uses some relatively new technology. Now I wanted to verify if this prototype is usefull and could be used in real world example. But now I have a problem, how can I do that? Normally, it would be a good thing to compare the prototype with already existing similar applications and compare if you perform better, provide better usability, etc. Since I'm not aware of something similar, this is quite difficult Normally, I would see if the requirements of the customers are met. But there aren't any real requirements and no real customers. It as just an idea. So the problem is, how can I get feedback on my prototype to see how it is accepted by potential users and what should be improved in a real implementation?

  • Reasons to use C++ ?

    - by RodH257
    I've read here and in other places that learning C++, C or other low level languages are a must to get a more low level perspective on development. I agree with this, but I find it hard to find a reason to use C++ over C# or similar languages. Most of the work I do is web based, so there's no need for C++ there. Other work is windows based, and most things work fine in C# there, so what sort of situation could I use C++? I don't do any high performance stuff, nor do I create games, mostly business applications. I'm looking for an excuse to expand on my C++ knowledge but I need some motivation other than 'because the internet said I should'.
