- by Claudiu

I'm running cm9 ics on my Galaxy Note and i tried anything i could find googleing around but to no result, if i look on the phone in usb settings there is the option for mass storage but it's grey and therefore not selectable I don`t know what the problem is but i saw somwhere that it might be an old version of libmtp so i tried to install libmtp 1.1.3 with ./configure make make install but even after when i try mtp-detect it gives me libmtp 1.1.1 is it normal? anyway when i run mtp-detect here is what it gives me libmtp version: 1.1.1 Listing raw device(s) Device 0 (VID=04e8 and PID=6860) is a Samsung GT-P7310/P7510/N7000/I9100/Galaxy Tab 7.7/10.1/S2/Nexus/Note.

How do you avoid working on the wrong branch?

- by henginy

Being careful is usually enough to prevent problems, but sometimes I need to double check the branch I'm working on (e.g. "hmm... I'm in the dev branch, right?") by checking the source control path of a random file. In looking for an easier way, I thought of naming the solution files accordingly (e.g. MySolution_Dev.sln) but with different file names in each branch, I can't merge the solution files. It's not that big of a deal but are there any methods or "small tricks" you use to quickly ensure you're in the correct branch? I'm using Visual Studio 2010 with TFS 2008.

Profiling NetBeans 7.0 Beta 2 and Reporting Problems

- by christopher.jones

With NetBeans 7.0 recently going into Beta 2 phase, now is the time to test it out properly and report issues. The development team has been squashing bugs, including memory issues with the PHP bundle.There are some great new PHP related features in NetBeans 7.0, so you know you want to try it out.If you identify something wrong with NetBeans, please report it following the guidelines http://wiki.netbeans.org/IssueReportingGuidelinesDepending on the issues, data to attach to the report is mentioned on: http://wiki.netbeans.org/FaqLogMessagesFile and http://wiki.netbeans.org/FaqProfileMeNowIf you have a memory issue then a memory dump would also be useful. Run the jmap tool for this. There is some background information on http://wiki.netbeans.org/FaqMemoryDump. Here's how I used it.First I set my environment to match the JDK used by NetBeans. In my case I am using a nightly build so the JDK is in the configuration file under $HOME/netbeans-dev-201102210501:$ egrep netbeans_jdkhome $HOME/netbeans-dev-201102210501/etc/netbeans.conf netbeans_jdkhome="/home/cjones/src/jdk1.6.0_24" $ export JAVA_HOME=/home/cjones/src/jdk1.6.0_24 $ export PATH=$JAVA_HOME/bin:$PATH Next, I found the correct process number to examine:$ ps -ef | egrep 'netbeans|jdk'cjones 23230 1 0 16:07 ? 00:00:00 /bin/bash /home/cjones/netbeans-cjones 23438 23230 2 16:07 ? 00:00:09 /home/cjones/src/jdk1.6.0_24/binFinally I used the parent JDK process as the jmap argument:$ jmap -histo:live 23438 num #instances #bytes class name---------------------------------------------- 1: 12075 9028656 [I 2: 49535 6581920 <constMethodKlass> 3: 49535 3964128 <methodKlass> 4: 80256 3840776 <symbolKlass> 5: 36093 3635336 [C 6: 5095 3341312 <constantPoolKlass> 7: 5095 2486016 <instanceKlassKlass> 8: 4325 1961432 <constantPoolCacheKlass> 9: 18729 1763976 [B 10: 59952 1438848 java.util.HashMap$Entry . . .This histogram memory report will help identify the kind of memory issues you are seeing. It may not be as complete as an often tens of megabyte jmap -dump:live,file=/tmp/nbheap.log 23438 heap dump, but is much more easily attached to a bug report.If you want to keep up to date with NetBeans, nightly builds are at: http://bits.netbeans.org/download/trunk/nightly/latest/zip/

Removing AppPrincipals from Office365

- by Sahil Malik

SharePoint, WCF and Azure Trainings: more information So here is an annoying issue. If I have your AppPrincipal and secret, I can party as you! But as we go through our usual dev cycles, we create these ApplicationIDs. Hell Visual Studio will create them for us, to make things easy!The problem is, many a developer, and some a ITOgre, may leave these AppPrincipalIds sitting there and not clean them up when they are done playing. You can look for currently registered App Principals at https://yourtenant/_layouts/15/appprincipals.aspx The problem is, that URL shows you App Principals registered AND currently in use. Currently NOT in use App Principals are NOT shown on that page. The same issue applies on premises also, even though here I am talking specifically about Office 365. Getting rid of these in On-Prem is easy, just use the Object model (server side). Read full article ....

Basic Ubuntu FTP Server

- by JPrescottSanders

I would like to setup a basic FTP server on my Ubuntu Server install. I have been playing with VSFTPD, but am having issues getting the server to allow me to create directories and copy files. I have set the system to allow local users, but it appears that doesn't mean I get access to create directories. This may be an instance where I need to be better grounded in Unbuntu server setup in order to configure this FTP server adequately. The end goal is to be able to move files from my local dev folder into my www folder for deployment. Directories need to be able to move as well. Any help would be greatly appreciated.

Android, OpenGL and extending GLSurfaceView?

- by Spoon Thumb

This question is part-technical, part-meta, part-subjective and very specific: I'm an indie game dev working on android, and for the past 6 months I've struggled and finally succeeded in making my own 3D game app for android. So I thought I'd hop on SO and help out others struggling with android and openGL-ES However, the vast majority of questions relate to extending GLSurfaceView. I made my whole app without extending GLSurfaceView (and it runs fine). I can't see any reason at all to extend GLSurfaceView for the majority of questions I come across. Worse, the android documentation implies that you ought to, but gives no detailed explaination of why or what the pros/cons are vs not extending and doing everything through implementing your own GLSurfaceView.Renderer as I did Still, the sheer volume of questions where the problem is purely to do with extending GLSurfaceView is making me wonder whether actually there is some really good reason for doing it that way vs the way I've been doing it (and suggesting in my answers to others to do). So, is there something I'm missing? Should I stop answering questions in the meantime? Android openGL documentation

How to hide bind mounts in nautilus?

- by Bazon

Summary: How do I remove folders mounted via bind or bindfs in /etc/fstab from appearing as devices in nautilus left column, the "places" view? detailed: Hello, I mount various directories from my data partition via bind in /etc/fstab in my home directory, eg like this: #using bind: /mnt/sda5/bazon/Musik /home/Bazon/Musik none bind,user 0 0 #or using bindfs bindfs#/mnt/sda5/tobi/Downloads /home/tobi/Downloads fuse user 0 0 (Background: /dev/sda5 mounted to /mnt/sda5 is my old home partition, but I do not want to mount it as a home partition, as I always have at least 2 Linuxes on the computer ...) That works well, but since 12.10 every one of those items is listed in Nautilus in the left column under "Devices". (Where normally USB drives appear, etc.) This is a waste of space (as I have many of such mounts...) and so I would like to have these mounts hidden, just as it was before in 12.04. How can I do that? Thanks!

How to retrieve data from a corrupted volume

- by explorex

Hi, My Ubuntu 10.10 just crashed, probably due to hardware error (and in the end I was getting errors like Unknown filesystem ..... grub> .., and it went to the GRUB console before I could take any other action). I reinstalled the same version from a USB stick. I had Ubuntu installed with the ext4 file system and I also have the same filesystem in the same hard disk on a different drive. When I try to access my previous filesystem, I get errors: Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sda6, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so I had some important files in the previous volume ; I don't know how to retrieve them. And what are the chances that I would get the same outcome (hardware error)? Please help me!

Asking about deleted partition at boot

- by Shawn Mitchell

I have Ubuntu installed through Wubi. I also had another partition on my computer to try out the dev preview of Windows 8 aptly named Windows_8. After I was done playing, I deleted the Windows 8 partition and added the extra space back to my Win7/Wubi partition. Now every time I boot into Ubuntu, it tells me that it can't mount the partition and asks me if I want to recover or skip it. Is there a way to get Ubuntu to forget about this partition so I can skip this extra step in my boot? Thanks

Where to start building a BaaS

- by Wesley

I'm building a Cloud Platform, and the next phase of design involves building an extensible BaaS back end. (see http://youtu.be/lNi-05-PyEw) The reason I think we can attempt this, is there are dozens of these kinds of extensible back end data proxy's popping up almost daily at this point, which tells me the enabling technology is there to build one from scratch in a few months. I'd like to start in the right area: What kind of Dev background should I look for? What kind of tech stack should I build on? What kind of costs can I expect in terms of man-hours, etc... I know there isn't one right answer here, but I think this is the right sub to post this in, and credit will go towards to most constructive answer.

TortoiseSVN and Subclipse icons not updating with SVN? [migrated]

- by Thomas Mancini

I have a repository on a network share with working directories on two separate machines. Upon making changes to my local working directory and committing them, the icons are not changing on the other developer's machine. If the Dev goes to Team Synchronize with Repository it shows the changes in the Synchronize view within Eclipse, however I was expecting the icon next to the project to change if it is not in sync with the repository. The same happens with TortoiseSVN in Windows Explorer. If we right click and check the repository for modifications it shows them, however the overlay icon on the directory is still the green check box. Am I just misinterpreting what I expect to happen, or is there a way to get these icons to change if the project is no longer in sync with the repository?

Google intègre le support de WebM à Chrome et rechange la licence du nouveau codec vidéo issu du VP8

Mise à jour du 07/06/10 VP8 vs H.264 : Google intègre le support du WebM à Chrome Et rechange la licence du nouveau standard vidéo issu du VP8 Les choses s'accélèrent pour le projet WebM issu du VP8, un standard vidéo que Google a décidé de rendre open-source, et du Ogg-Vorbis (lire ci-avant).

How can I generate signed distance fields (2D) in real time, fast?

- by heishe

In a previous question, it was suggested that signed distance fields can be precomputed, loaded at runtime and then used from there. For reasons I will explain at the end of this question (for people interested), I need to create the distance fields in real time. There are some papers out there for different methods which are supposed to be viable in real-time environments, such as methods for Chamfer distance transforms and Voronoi diagram-approximation based transforms (as suggested in this presentation by the Pixeljunk Shooter dev guy), but I (and thus can be assumed a lot of other people) have a very hard time actually putting them to use, since they're usually long, largely bloated with math and not very algorithmic in their explanation. What algorithm would you suggest for creating the distance fields in real-time (favourably on the GPU) especially considering the resulting quality of the distance fields? Since I'm looking for an actual explanation/tutorial as opposed to a link to just another paper or slide, this question will receive a bounty once it's eligible for one :-). Here's why I need to do it in real time: There's something else:

Lead/Manager vs Individual contributor which is better?

- by User11091981

Currently I am working in a company as a Manager (software dev). But I only have 6.8 yrs experience. I joined this company as a software engineer and got promoted to SSE, Lead and Manager. Some of my team members are having better experience than me, and I feel like I need to have more exposure/experience to take these roles. I feel like it is better to be an individual contributor learn many things for another couple of years and become a Principal Software Engineer, rather than involving in Management. Options I have: 1. Ask my current employer to make me an individual contributor? 2. Find a new company and join as an SSE to start over? 3. Find a new company for a lead position? Please advice.

Wubi install: How do I increase swap size

- by Diogenes Lantern

I am trying to increase the swapfile size on my WUBI install. I followed the answer here: sudo su swapoff -a cd /host/ubuntu/disks/ mv swap.disk swap.disk.bak dd if=/dev/zero of=swap.disk bs=1024 count=2097152 mkswap swap.disk swapon -a free -m until I reached: mv swap.disk swap.disk.bak At which point I have got got the following: root@ubuntu:/host/ubuntu/disks# mv swap.disk swap.disk.bak mv: cannot move `swap.disk' to `swap.disk.bak': Operation not permitted My 256 M swap space is all used up. I would like to install a total of twice that. Is there a method of setting it which would not include guesswork on my part?

How do I get the Grub menu back after installing Windows on a separate disk?

- by Shazzner

Tried sudo grub-install on sda1 but it complained about being a BAD IDEA. I had to install windows for a work related issue so I used a separate disk (I had used it for ubuntu on this computer, but bought a bigger disk so installed ubuntu on that and left the old one in in case I needed an old file). Windows installed fine but overwrote Grub. So if I choose the Ubuntu disk to boot first in BIOS I get a blank screen. I googled and followed this advice: https://help.ubuntu.com/community/RecoveringUbuntuAfterInstallingWindows However, when I get down to this section: sudo grub-install --root-directory=/media/0d104aff-ec8c-44c8-b811-92b993823444 /dev/sda1 I get this: Attempting to install GRUB to a partition instead of the MBR. This is a BAD idea… --recheck does nothing. Any ideas?

How to keep a team well-trained?

- by PierrOz

Hi dear fellows, I'm currently mentoring a small team of 4 junior dev in small software company. They are very smart and often achieve their tasks with a high-quality job but I'm sure they still can do better - actually I have exactly the same feeling for myself :) -. Besides some of them are more "junior" than other. So I would like to find of a funny way to improve their CS skills (design, coding, testing, algorithmic...) in addition to the experience they acquire in their daily work. For instance, I was thinking of setting up weekly sessions, not longer than 2 hours, where we could get together to work on challenging CS exercises. A bit like a coding dojo. I'm sure the team would enjoy that but is it really a good idea? Would it be efficient in a professional context? They already spend all their week to code so how should I organize that in order for them to get some benefits? Any feedback welcome !

Ubuntu 12.10 - VirtualBox not sharing internet with guest system

- by Fernando Briano

I went from ArchLinux to Ubuntu on my dev box. I use VirtualBox to test web sites on Windows and IE. I have my Windows 7 VirtualBox image running on Ubuntu's VirtualBox. Back with ArchLinux, internet worked "out of the box" on the Windows boxes. I left the default options on the box's Network Options (NAT). The Windows machine shows as "connected to ethernet" but reports: The dns server isn't responding So I can't access Internet from there. I tried searching for Ubuntu's official docs but they seem pretty outdated. I tried using my old boxes from Arch (which boot normally but have no internet) and creating a new box from Ubuntu itself, but still get the same results. Update: I'm using VirtualBox 4.1.18 from Ubuntu's repository (apt-get install virtualbox).

Error while trying to dual boot Ubuntu alongside Windows 8

- by Brian

I recently purchased a new Toshiba Ultrabook that comes pre-installed with Windows 8. I'm trying to dual boot 12.10 with it and I have run into a problem with the installer. When I get to the page to pick the partitions I get this: No drives are listed and the only thing in that device drop down is /dev/sda. If I click Install Now or +/-/change I get an "Ubuntu has stopped working" error message. I'm trying to install off a 12.10 64-bit USB drive in UEFI mode, and I have tried it with secure boot both enabled and disabled with the same results. The hard drive set up is as follows: 500 GB main drive windows recovery (primary) EFI boot section (primary) Windows' partion (280 GB I believe) (primary) unallocated space I created for Ubuntu partition (200ish GB) another Windows recovery partition (primary) 12 GB solid state drive all unallocated space Could it be a problem with the number of primary partitions? I think I read somewhere about a max of 4.

I/O errors are reported when I try to install Ubuntu, but the SMART data is good. Is my hard disk dying?

When I try to install linux, it tells me there is an input output error on dev sda. I have tried both Ubuntu and Mint on two different computers. So that narrows it down to the hdd. After hours of googling and trying different things I tried making the hardrive ext4 with gparted but that comes up with an error. This makes me think that the hdd is bad. There are a few reasons I think the hdd isn't bad. I can use the hdd in windows fully. Windows and gparted disk health checks both say it is fine. Its SMART data is all good. So... help?

Remove encryption from USB flash drive

- by Timic

It all started when I was attempting to format my PNY USB drive because it was full of junk. When it asked me what type of file system, I selected FAT but there was a checkbox below that said "Encrypt" and I accidently checked it and continue. I had no choice but to come up with a passphrase for it, and so I did, thinking I was able to remove that encryption. But after that at Disk Utility I thought I would find a "Remove Encryption" button or something like that but I didn't. I tried formatting it to remove the encryption but it gives me an error: Error Formatting, The device is busy" Detail>>> One or more block devices are holding /dev/sdb/. I am stuck, what should I do?
