  • Does attending the upcoming Devdays 2011 have some value for a resume?

    - by systempuntoout
    This fall I'm 99% going to London to attend the awesome Devdays 2011; I have many reasons to go there and some of them are: Professional stuff Great people Awesome topics Unicorns Passion London :) Obviously all the cool technologies that will be discussed are light years far from my daily work but useful for my side projects and maybe for some future employment. Now, to get to the point; a coworker said to me that he won't come with me because Devday London is expensive, and something expensive should reward you with a certificate, a certificate that could have some value to the eyes on an employer. Is he right? Do you think that attenting to this kind of event have some value on a resume? Should it be highlighted? Does it have any value for a future employer?

  • Why is Android VM-based? [closed]

    - by adib
    By about 2004, it was clear that ARM is the clear winner for mobile CPUs, beating out MIPS, SH3, and DragonBall. PocketPC (Windows Mobile) applications was natively-compiled (at least most of them - except for .NET compact and its competitors). Likewise, Apple's iOS (named iPhone OS at the time) prefers natively-compiled applications. Then why Android chose a virtual machine based system stack? (the Dalvik VM). Wouldn't it be simpler to just compile applications down to ARM code using GCJ or something? Is the decision influenced by the J2ME-way of doing things, or was just because it's "cool"? Perhaps like most things Java, the culture that prefers multiple levels of indirection and abstractions, they just added another layer of abstraction for "just in case"?

  • How to get rid of the orange highlight in Unity?

    - by user74660
    I've installed Ubuntu 12.04 LTS and I'm using Unity. I also installed Adwaita theme and Elementary icons. Everything is cool. Highlightings are blue, as I want them to be, but there are some places where the default orange color remains: When clicking on Workspace Switcher, the borders of the current or the selected workspace are still orange. When dragging a window to the edges of the screen, the highlight effect for the Snap Window feature is still orange as well. All other highlights are blue, according to the Adwaita theme. So, how can I get rid of those two mentioned orange highlights and turn them into blue, following the Adwaita color theme? Thanks for your attention. brunces

  • My Obligatory IPad Post

    - by mark.wilcox
    I've had my IPad for about a week now. So I thought I'd write some thoughts down based on my initial experiences. Here are my initial take-aways: 1 - Netflix OnDemand - I'm a movie junkie. I'm now more apt to just start a movie as background sound for my workday (I telecommute - so except for the occasional bark from my dog, it's awfully quiet here if I don't have something going). 2 - The Email Client is really nice and I'm as fast or faster typing when I have the wireless keyboard engaged. Even with onscreen keyboard - I'm already close to 75% of desktop speed 3 - The battery life is incredible - I think this is the first case where a mobile device actually under-promised on battery 4 - It totally has killed the notion of using a normal PC for my wife and mother-in-law - neither of which had wanted an iPhone/iPod Touch or really any Apple device until they got to play with my iPad. The concept of - instant on, easy to hold and touch-based navigation has them hooked. Heck, it has me hooked. My ultimate goal is to be able to have it at least replace the need to take my netbook with me on the road. I haven't had a chance to complete my testing on that front yet - between work, my wife traveling (for a change) and now my wife home sick - I haven't had time to just play with it. But so far my only regret - that I haven't already bought two more for everyone else in my family who wants to use mine. Posted via email from Virtual Identity Dialogue

  • easy visualization of usage statistics (web app)

    - by sova
    I have some usage queries for my web app's database, the results of which I want to display graphically. Is there an easy-to-use api that exists for this purpose? I want to show things like average query-time per user (a small user-base), average query time per day, and things like that. I think it would be cool to show these on a two-axis graph. I am displaying this data on my site, so a jQuery/javascript/html solution for rendering information into graphs would be ideal. Thank you :) P.S. I wasn't sure if I should ask this on SO, but I am looking more for which product to use, not how to program with it.

  • Ubuntu won't load, freezes on purple screen

    - by kara
    Last time I restarted my computer, I could not get Ubuntu to load; the screen would either go black, or would hang at the purple screen indefinitely. I have had some graphics problems in the past, but had put 'nomodeset' after 'quiet splash' in the grub command line, which at least let Ubuntu load. That doesn't work now, and doesn't work if I remove it. I looked up some answers, such as this one: Purple start screen - no splash screen However, when I enter the root in recovery mode in grub, I always get errors when I run those command lines and it won't let me modify the files. Also, if I run in recovery mode and then choose 'resume normal boot', it will continue. But instead of getting a usual interface, I get a black screen that asks for my username and password. I enter these, and it tells me I'm in Ubuntu 12.04, but I'm still on a black screen with texts. It also informs me that there are updates to install. When I use the command 'sudo apt-get update', it starts to retrieve the information, but then the screen goes blank after a couple of seconds and I can't do anything anymore. Any ideas?

  • How to support tableless columns with WYSIWYG editor?

    - by Andy
    On the front page of a site I'm working on there's a small slideshow. It's not for pictures in particular, any content can go in, and I'm currently setting up the editing interface for the client. I'd like to be able to have one/two/more columns in the editable area, and ideally that would be via CSS - does anyone know of a WYSIWYG editor that supports this? I'm using Drupal (would prefer not to involve Panels as it would require a bit of work to make it a streamlined workflow for content entry) in case that matters to anyone. To start the ball rolling, one way would be to use templates. I know CKEditor supports templates, and it looks like TinyMCE might have something similar. I don't know how well these work with tableless columns (the CKEditor homepage demo uses tables to achieve its two column effect). Holding out for a cool solution!

  • What's New in Oracle Secure Global Desktop 5.1 webcast

    - by Chris Kawalek
    We have a really exciting webcast coming up for you this week that will tell you all about what's new in Oracle Secure Global Desktop 5.1. Hosted by Andy Hall, you will learn all the exciting features in this brand new release! What's New in Oracle Secure Global DesktopThursday, November 7, 9AM Pacific TimeRegister now. If you'd like a sneak peek, hop on over to the Fat Bloke Sings, where Fat Bloke goes into detail on some of the new features. My favorite is accessing your applications (or even full desktops) from SGD using just the Chrome web browser. In this graphic, Fat Bloke is running Oracle Linux via SGD and accessing with Chrome on the Mac. This required no installation on the client, no dependencies on any other software, nothing -- just open up Chrome, login, and all of your stuff is there. Very cool.  We hope to see you on Thursday! -Chris

  • Should I learn GWT (I'm a Java newb) if I eventually want to learn JavaScript and related libraries?

    - by Aaron
    I haven't been working with Java for a long time, and I found GWT to be interesting plus a chance to learn and practice Java. My goal for this year is to learn JavaScript. I'm very interested in HTML5, browser extensions and other cool stuff that JavaScript can do. I think I'm more interested in this than Java at the moment (that's not to say I dislike or would discontinue working with Java) but I would like advice as to whether it's a good idea to proceed with learning GWT (given my interest in JavaScript) or to spend my time learning other Java technology. Thank you.

  • Is there a way to make catalyst driver work in Trusty for the radeon hd4330?

  • Issue in Webscrapping in C# : Downloading and parsing zipped text files

    - by user64094
    I am writing an webscrapper, to do the download content from a website. Traversing to the website/URL, triggers the creation of a temporary URL. This new URL has a zipped text file. This zipped file is to be downloaded and parsed. I have written a scrapper in C# using WebClient and its function - DownloadFileAsync(). The zipped file is read from the designated location on a trapped DownloadFileCompleted event. My issue : The Windows 'Open/Save dialog is triggered". This requires user input and the automation is disrupted. Can you suggest a way to bypass the issue ? I am cool with rewriting the code using any alternate libraries. :) Thanks for reading,

    - by tehp
    Possible Duplicate: How to mute the sound output on Windows Start up? I carry a laptop around. Sometimes I'll open it up in meetings or other quiet settings. The speaker is interrupted by the windows startup noise or Pandora refreshing it's page and starting to play a song or some other random computer noise. Is there a simple way to mute the sound on startup/resume/whatever? Kind of like the BIOS option to turn on or off the Num Lock.

  • Where have I been for the last month?

    - by MarkPearl
    So, I have been pretty quiet for the last month or so. True, it has been holiday time and I went to Cape Town for a stunning week of sunshine and blue skies, but the second I got back home I spent the remainder of my holiday on my pc viewing tutorials on www.tekpub.com Craig Shoemaker, who I got in contact with because of his podcast, sent me a 1 month free subscription to the site and it has been really appreciated. I have done a lot of WPF programming in the past, but not any asp.net stuff and so I used the time to get a peek at asp.net mvc2 as well as a bunch of other technologies. I just wished I had more spare time to do the rest of the videos. While I didn’t understand all of what was being shown on the asp.net stuff (it required previous asp.net expertise), the site was a really good jump start to someone wanting to learn a new technology and broaden the horizons and I would highly recommend it, My only gripe is that in South Africa we have limited bandwidth and bandwidth speeds and so I spent a lot of my monthly bandwidth on the site and had to top up with my ISP several times because of the high quality video captures that the site did. I would have preferred to download the video’s, but apparently that is only available to people who have the yearly subscription fee. Other than that, great site and thanks a ton Craig!

  • Ubuntu won't start - blank screen with flashing white cursor

    - by loomy
    My laptop is dual-booted with Windows 8 on one partition and Ubuntu 12.04.3 on the other. I've searched for my issue already, but nothing I've found so far has solved the problem. Since last week, when I try to boot Ubuntu from GRUB, I am taken to a purple screen (as usual), but then to a black screen with a blinking white _ cursor. I've tried leaving it, but nothing else happens. When I hold Shift and edit the GRUB entry to change 'quiet slash' to 'text', the back screen instead asks for my login and password. When I put them in, it tells me the date of my last logon, and then waits for further commands. Being very very new to Ubuntu, I have no idea at all what to try out at this point. I tried to launch FailsafeX, but while that was beginning, it said "unable to run server /usr/bin/x" No such file or directory", then shortly after returned to the recovery mode menu. Pressing Ctrl+Alt+Delete goes through an Ubuntu loading screen, then the laptop then restarts. Any suggestions will be very appreciated, and apologies if this is a common issue that has been answered a million times before.

  • Is there a way to change the root password while still logged in? I did something bad by accdient -_-

    - by Robert
    So I was trying to add my printer, and I wasn't able to make any changes due to the fact that cups was not accepting my root password. I was Googling some changes and trying to fix the problem when one of the commands CHANGED MY SUDO PASSWORD! Can someone please tell me which one of these is the culprit? I was trying to these commands: cat /etc/group | grep root cat /etc/group | grep myUserName usermod -a -G lpadmin myUserName sudo usermod -a -G lpadmin myUserName sudo gedit /etc/cups/cupsd.conf lppasswd -a myUserName lppasswd -a root sudo lppasswd -a myUserName I think it was this one, but I know which passwords I put in! There was nothing which I typed in besides my strong password or my easy temporary password. Unless I made a typo... please no. restart cups sudo password root This is so not cool, I was just trying to add a printer :'( Please help my stupidity!

  • Ubuntu 13.10, kernel 3.11 blank screen issue with hybrid graphics

    - by Lagerbaer
    On my HP Envy, which has both an Intel on-chip graphics card and an Nvidia Geforce: *-display UNCLAIMED description: 3D controller product: GK208M [GeForce GT 740M] vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: cap_list configuration: latency=0 resources: memory:d2000000-d2ffffff memory:a0000000-afffffff memory:b0000000-b1ffffff ioport:5000(size=128) memory:b2000000-b207ffff *-display description: VGA compatible controller product: 4th Gen Core Processor Integrated Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 06 width: 64 bits clock: 33MHz capabilities: vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:46 memory:d3000000-d33fffff memory:c0000000-cfffffff ioport:6000(size=64) I have trouble with all newer kernels. I basically had to install 12.04 LTS and use their 3.5 kernel family to get the system to boot. The 3.8 from 12.10 or the newest 3.11 from Ubuntu 13.10 leave me with a black screen upon boot. On one occasion I did hear the "log in" sound, but the screen did not display anything. I have purged all nvidia drivers so I guess it should just use the intel drivers, but apparently this is all messed up with newer kernel versions. This is different from the other "nvidia boots into blank screen" bug in that I don't rely solely on an nvidia card. Surely the intel on-chip card should be supported and leave me with something different from a blank screen? Again, it only works with kernel versions 3.5.0-41-generic, not with the 3.11.0-12 one that ships with Ubuntu 13.10. When I go into the grub menu and change the boot options from 'quiet splash' to 'nomodeset' I am able to boot the system, but then I don't get any graphics and trying 'sudo service lightdm start' doesn't succeed (I get 100% CPU for apport, but this doesn't do anything either, so I kill it). Help, I'm all out of ideas. EDIT: Let me add that I'm using the EFI boot system and have a dual-boot installation with Windows 8.

  • NetBeans "Find Usages" Tool Integrates JSF Expression Language

    - by Geertjan
    I saw this by Adam on Twitter today: Interesting. Let's try it. Here's my method "getCustomerId". I select it, right-click, and choose "Find Usages" (or press Alt-F7): A nice dialog appears: Then click "Find" and, guess what, this is what I see (click to enlarge it): Clearly, as you can see, I'm not only finding the Java controller class where the getter is used, but also the Facelets files, and, within those, the exact lines where the JSF expression language makes use of the getter. This is not a new feature, tried it and got the same result in 7.1.1, but it's really cool to know about nonetheless.

  • 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!

  • Linux Software Raid runs checkarray on the First Sunday of the Month? Why?

    - by mgjk
    It looks like Debian has a default to run checkarray on the first Sunday of the month. This causes massive performance problems and heavy disk usage for 12 hours on my 2TB mirror. Doing this "just in case" is bizzare to me. Discovering data out of sync between the two disks without quorum would be a failure anyway. This massive checking could only tell me that I have an unrecoverable drive failure and corrupt data. Which is nice, but not all that helpful. Is it necessary? Given I have no disk errors and no reason to believe my disks have failed, why is this check necessary? Should I take it out of my cron? /etc/cron.d# tail -1 /etc/cron.d/mdadm 57 0 * * 0 root [ -x /usr/share/mdadm/checkarray ] && [ $(date +\%d) -le 7 ] && /usr/share/mdadm/checkarray --cron --all --quiet Thanks for any insight,
