• Ubuntu Studio Audio Issue with Alsa - No sound

  - by ddragon

  Spec: OS: Ubuntu Studio 13.10 64bit CPU: AMD FX 4100 Quad Core Memory: 6GB DDR3 Video: Radeon HD 4250 (embedded on the mobo) Sound: Delta 66 PCI Issue: I just installed Ubuntu Studio and found out that the streaming audio on a few common website such as Youtube had no sound, and also my CD/DVDs via a player. Thus, in the terminal, I entered: sudo alsa force-reload It actually worked but the sound/audio output was MONO and NOT Stereo (the sources are set to stereo stereo), and it seemed I was not able to locate any settings that can switch the output sound to stereo at all. I went through many forums and eventually "autoremove" pulseaudio since many said I would not be able to utilize both pulseaudio and alsa in this case. Now, I have no audio whatsoever. Does this version of Ubuntu only offer mono sound/audio no matter what I do? Then, I may just need to ditch the whole thing and go back to Windows, which I don't want to since Ubuntu Studio offers many great apps, soundfonts etc.. I have also installed restricted extra, but even after rebooting, it did not resolve the issue. In the terminal mode, I pulled "alsamixer" and unmuted almost everything. But still no sound after a reboot. Just an FYI, I have no saved data under this version of Ubuntu Studio yet, so please feel free to let me know whether I need to install Studio 12.10 instead or mess with some installing/uninstalling apps/plug-ins, etc... If it breaks at some point, all I need to do is to re-install it, which I do not mind at all. Or, if you can provide me a step by step instruction to get this work, I do not mind clean install the Studio 13.10 then wait for your instruction AT ALL!

• Testing home directory scripts by setting $HOME to the location of the test directory

  - by intuited

  I have an interdependent collection of scripts in my ~/bin directory as well as a developed ~/.vim directory and some other libraries and such in other subdirectories. I've been versioning all of this using git, and have realized that it would be potentially very easy and useful to do development and testing of new and existing scripts, vim plugins, etc. using a cloned repo, and then pull the working code into my actual home directory with a merge. The easiest way to do this would seem to be to just change & export $HOME, eg cd ~/testing; git clone ~ home export HOME=~/testing/home cd ~ screen -S testing-home # start vim, write/revise plugins, edit scripts, etc. # test revisions However since I've never tried this before I'm concerned that some programs, environment variables, etc., may end up using my actual home directory instead of the exported one. Is this a viable strategy? Are there just a few outliers that I should be careful about? Is there a much better way to do this sort of thing?

• How do you KISS ?

  - by Conor

  The KISS principal is a highly quoted design mantra. The aim of this principle is to stamp out unnecessary complexity on a project. This is a good thing, saving time, energy and money. It can lead to a relatively stress free implementation and a simple, elegant, maintainable end product. A lot of discussion on KISS provides mechanisms to simplify requirements, design and implementation. Things that spring to mind include: avoid scope creep; simple obvious design and code; minimal run-time dependencies; refactoring to maintain simplicity; etc. However there are a lot of implicit things that we do to KISS. Examples: small team sizes; minimal management layers; tidy desk; mastery of a single IDE; clear concise error messages; scripts to automate/encapsulate tasks; etc The purpose of this question is to derive a checklist of KISS items. I'm especially interested in non-obvious items.

• HP OfficeJet 5600 w/ Dlink DPR1260 not printing except from Notepad

  - by joelarson

  I have an OfficeJet5600 attached to a Dlink DPR1260 wireless print router. It has worked great for a long time. Today we had a power outage and the thing was inaccessible. I reset the DPR1260 and reinstalled drivers and soforth. I can now print from Notepad, but not from any Office programs, IE, or Chrome. I have toggled on and off many settings such as spooling/not spooling, etc. Nothing has helped. Any ideas? I have Windows Vista.

• SyncToBlog #11 Stuff and more stuff

  - by Eric Nelson

  Just getting more stuff “down on paper” which grabbed my attention over the last couple of weeks. http://www.koodibook.com/ is live. This is a a rich desktop application built in WPF by some ex-colleagues and current friends :-) Check it out if “photo books” is your thing or you like sweet WPF UX. Study rates Microsoft .NET Framework rated top, Ruby on Rails 2nd bottom. I know a bit about both of these frameworks. Both are sweet for different reasons. .NET top. Ok – I liked that. But Ruby on Rails 2nd bottom just blows away the credibility of the survey results for me. Stylecop is going Open Source. Sweet. ”…will be taking code submissions from the open source community” VMforce for running Java in the cloud. Hmmmmm… Windows Azure Guidance Code and Docs available on patterns and practices. Download both zip files. – One is just the code and the other is 7 chapters of the guide to migration.

• Which Single Source Publishing tools and strategies are available?

  - by Another Registered User

  I'm about to write a 1000-Pages Documentation about a huge programming framework. The goal is to bring this documentation online into an web platform, so that online users can search through it and read it online. At the same time, the text has to be made public in PDF format for download. And at the same time, the whole thing needs to go into a printed book as well (print on demand, they want a giant PDF file with the whole book). The PDF files: The whole content is divided into several chapters. Every chapter will be available as a standalone PDF eBook. And finally, all chapters will be available in one huge printed book. Is LaTeX capable for something like that? Can it be used for Single Source Publishing? Or would I have to take a look at other technologies like DocBook, etc.?

• Nano suddenly putting in weird characters when I type

  - by Cocorico

  I am using a shell and editing a file in nano (similar to pico). A short while ago, it started doing this thing where if I type: $query = "select" * from topics where id='' "; and then I hit Backspace and try to stick the letter 'a' into the id='' part, it changes it to: $query = "select * from koala_topics where id='a='' "; and the cursor jumps around to a few spaces before. Also if I type print At the start of a new line, and then I think "Oh I should have added a tab" and I go back and try to add a tab, it adds a tab AND 2 spaces, and if I put the cursor through the word print, it turns into printnt. Some other weird things have happened too. I uninstalled nano using yum (which is how I installed it), and then re-installed it, thinking that would get me clean preferences (in case that was the problem) but it doesn't fix it.

• Create Webmin user for an EC2 Instance

  - by Dean

  I've setup an Amazon EC2 Instance, using the Ubuntu 12.04 AMI (ubuntu/images/ebs/ubuntu-precise-12.04-amd64-server-20120424 (ami-a29943cb)), and I'd like to get Webmin working (so I can setup a DNS). After following the installation instructions on Webmin's site, the installer says I can login with any username/pass of a user who has superuser access. The problem is that the EC2 instance only has 1 user "ubuntu", which can only login using SSH keys -- not a password! I've tried creating users manually and I can't login as those users (even via SSH), so I think it might be a permission thing provided by the AMI. Does anyone know the best way around setting up a login to my webmin?

• Wubi doens't work anymore - shows 'No wubildr' error

  - by Joe

  Basics: HP Mini 311 Ubuntu netbook edition 10.04 (installed via Wubi) Symptoms: I load to Windows Boot Manager as usual. Options are Windows 7 and Ubuntu Netbook, like usual. Selecting Windows 7 does as it should. Loading Ubuntu Netbook, though, does not take me to the usual screen where it lets me select versions of Ubuntu (sorry for bad wording, not sure what the real name is called; it's where you select from about 6 items; I always picked the first due to lack of knowledge without issue). Instead it flashes an error in white on a black screen then restarts very quickly. It took me a few restarts, but here is the error: Try (hd0,0): NTSF5 No wubildr Try (hd0,1): NTSF5: Situation: I have no clue what caused it. The only thing I did last night on Ubuntu was install Skype, but the mic didn't work instantly so I got lazy and switched to Windows 7 and used Skype on there. When I tried to switch back to Ubuntu it began this. (There may be something I forget... it was 5 in the morning). There were no recent updates that I remember. No weird activity. Just... random. Help please?

• VM can't connect to outside in bridged mode

  - by Kamal

  I am not able to ping any machine(not even the host) from Guest VM in bridged mode. But I got an IP which is on the same subnet as host. I can ping my guest VM from the host and can use ssh to connect to the guest. I am using Vmware workstation 6.5. Guest VM is a centos VM and host is windows xp. Every thing works fine in NAT mode. Any clues as to what could be happening. I tried disabling all the firewalls I have.

• How to change the fonts used in Foxit Reader?

  - by user982438

  I really want to use Foxit Reader as my default PDF reader for its Tab Interface, and low memory footprint. Having tried mutiple times over the years the only thing that is stopping me are the Fonts. PDF in Adobe Reader looks Regular, but PDF Rendered in Foxit Looks Ugly. Would this solution works in Chrome as well? Since i record Chrome is using Foxit Reader as its embedded PDF engine. And is there any reasons why Fonts are used differently in Adobe and Foxit Reader?

• Overriding Debian default groups from LDAP

  - by Ex-Parrot

  This is a thing that has always bothered me: how am I best to handle Debian standard groups for LDAP users? Debian has a number of groups defined by default, e.g. plugdev, audio, cdrom and so on. These control access in standard Debian installs. When I want a user from LDAP to be a member of the `audio' group on all machines they log in to, I've tried a few different things: Adding them to the local group on the machine (this works but is hard to maintain) Creating a group in LDAP with the same name and a different GID then adding the user to that group (breaks reverse / forward GID mapping, doesn't seem to work) Creating a group in LDAP with the same name and same GID and adding the user to that group (doesn't seem to work at all, things don't see the LDAP group members) Creating a group in LDAP with the same name and same GID then removing the local group (this works but upsets Debian's maintenance scripts during upgrades that check for local system sanity) What's the best practice for this scenario?

• Executing a Batch file from remote Ax client on an AOS server

  - by Anisha

  Is it possible to execute a batch file on an AOS server from a remote AX client? Answer is yes, provided you have necessary permission for this execution on the server. Please create a batch file on your AOS server. Some thing as below for creating a directory on the server.    Insert a command something like this in a .BAT file (batch file) and place any were on the server.   Mkdir “c:\test”      Copy the following code into your server static method of your class and call this piece of code from a button click on Ax form. Please execute this button click from a remote AX client and see the result . This should execute the batch file on the server and should create a directory called ‘test’ on the root directoryof the server.     server static void AOS_batch_file_create() { boolean b; System.Diagnostics.Process process; System.Diagnostics.ProcessStartInfo processStartInfo; ; b = Global::isRunningOnServer(); infolog.add(0, int2str(b)); new InteropPermission(InteropKind::ClrInterop).assert(); process = new System.Diagnostics.Process(); processStartInfo = new System.Diagnostics.ProcessStartInfo(); processStartInfo.set_FileName("C:\\create_dir.bat"); // batch file path on the AOS server process.set_StartInfo(processStartInfo); process.Start(); //process.Refresh(); //process.Close(); //process.WaitForExit(); info("Finished"); }

• What happens to modern-ui apps when they aren't in the foreground?

  - by Mark Allen

  If I start a modern-ui app and then switch to a different app or a normal program running on the desktop, what happens to the first app? I've heard something about the first app being suspended, but realized that I don't really know that for certain. I mean, could you write a SETI@Home (BOINC) app if you wanted to, or will apps that aren't in the foreground always be suspended? Can you change that? I could see changing that based on available resources, running from AC vs. battery, etc. This morning I heard about an iPad being recovered thanks to the "Find my iPad" app, and was wondering whether you could write such a thing as a modern-ui app and have it work without being the running foreground app. (I'm aware that you'd just write a Windows service or similar, that's not what I'm asking about.)

• Simple recursive DNS resolver for debugging (app or VM)

  - by notpeter

  I have an issue which I believe is caused by incorrect DNS queries (doubled subdomains like _record.host.subdomain.tld.subdomain.tld) when querying for SRV records. So I need to an alternate DNS server with heavy logging so I can see every query (especially stupid ones), acting as a recursive resolver with the ability create records which override real DNS records so I can not only find the records it's (wrongly) looking for, but populate those records as well. I know I could install a DNS server on yet another linux box, but I feel like this is the sort of thing that someone may already setup a simple python script or single use vm just for this purpose.

• ESET Remote Administrator Console showing infected files on a client, but threat log is empty

  - by Aron Rotteveel

  We recently deployed ESET NOD32 Antivirus on our small domain network and use the Remote Adminstrator to manage everything remotely. On a recent full system scan, one of the clients shows 10 infected files of which 4 have been cleaned in the scan log. The strange thing, however, is that the threat log is empty. Is there any reason why the threat log is empty? What has happened to the 6 remaining uncleaned files? Where can I view information on what files are infected and what they have been infected with? I know this can be done through the scan log properties screen, but with 958790 files scanned, I obviously do not want to browse through this list. Any help is appreciated.

• Set-and-forget Windows backup software with NAS-support?

  - by Evert

  I am looking for set-and-forget backup software for Windows (Vista & 7, and if possible XP/2003). The idea is that it runs in the background on the clients, and does its thing towards a network-share. In case the HDD of one of these clients spontaneously combusts, all I want to have to do is: replace the drive, insert a USB-stick, boot from it, and restore the machine. It should support drives which use [ICH]-RAID. What are my options here? It looks like WHS meets all the requirements, but I am curious about my other options here.

• I thought the mac mini server also serves as a wifi router?

  - by erotsppa

  I just bought a snow leopard mac mini server, everything came as a bundle pretty nice. The snow leopard server software preinstalled on the mac mini too. Only thing I'm not sure about is does this also act as a wifi router? In the back of the box it says "airport extreme wireless networking included", I assumed this means that this can act as a wifi router like an aiport extreme? Is this true? If so, how do I do it?

• [MINI HOW-TO] Update Your Zune Player Software

  - by Mysticgeek

  Keeping your computer and software up to date is very important in keeping everything running smooth and secure. It’s also important to keep your geeky gadgets updated as well. Here we take a look at updating a Zune HD. Note: In this example we’re updating a Zune HD out of the box which hasn’t been updated yet. The first thing you’ll need to do if you haven’t already is download and install the latest Zune software (link below). Now plug your Zune into your computer with the included USB connection cable and give it a moment to be recognized. Next launch the Zune Desktop software and you should get the following screen. Just accept the EULA… Then the update kicks off. Make sure not to disconnect the Zune while the update takes place. The update will take a few minutes, and after it’s complete you should be good to go and can start using your Zune. To update your player in the future, go to General Settings then Player Update. Just like your computer’s hardware and software, you want to keep your other geeky gadgets updated as well. This will help the device run more smoothly, and sometimes add additional functionality.

• mplayer dumpstream sometimes fails

  - by User1

  I'm trying to rip the video at http://videolectures.net/ecml07%5Fgetoor%5Fisr/, so I can play it at a faster speed. I paste http://193.2.4.216/2007/pascal/ecml07%5Fwarsaw/getoor%5Flise/ecml07%5Fgetoor%5Fisr%5F01.wmv into a firefox browser in Windows and MediaPlayer plays the thing. However if I try mplayer -dumpstream, it gets stuck into an infinite loop trying to play the file. If I use wget to download the link, I get a small text file which basically points to the same URL. How can I get mplayer to download this stream?

• Wire Framing WP7 Apps With Cacoo

  - by Tim Murphy

  While looking for a free alternative to Sketchflow I landed on the Cacoo web site.  Any developer who decides to use the free Visual Studio tools may find themselves doing the same search.  The base functionality of Cacoo is free although there are certain features that have fees attached to them such as extended stencils and templates. Cacoo doesn’t seem to have a template for WP7.  It does have templates for iOS and Android development so I started with the Android template and started modidfying it for WP7.  Funny thing is since Android has the same hardware vendors as Windows Phone the basic frame looks just right (I would swear I was looking at my Samsung Focus). Below is the start of a new mockup for the user group that I help run. I found that while Cacoo doesn’t have all the icons I need I am able to insert them from the Windows Phone Toolkit folder.  If I put them off to the side as you can see above.  I can simply copy and paste them into the appropriate place as needed.  Beyond that I have customized the main frame frame so I can have my base to work from.  In the future I intend to create this as a stencil and if it looks good enough I would consider making it public. My use of this product is still in it’s early phase, but it seems like a great way to start.  Maybe if you use this to get going you can earn enough from your resulting apps to pay for something with more bells and whistles in the future. del.icio.us Tags: WP7,Windows Phone 7 development,design,Cacoo,wire frame

• Moving from Test Automation to Development

  - by avgvstvs

  I'm in an interesting quandary. I've been doing test automation using QTP for about 1.5 years, and am in the slow process of switching to a developer role in my same company. I also begin my Master's in CS this fall. An old friend is trying to recruit me for a Sr. Test Automation position that could potentially pay me $23k more for the exact same thing I do now. But obviously I would defer moving to development. The new company is much more technical overall (I would be moving from financial services to industrial automation, and they have MANY more software dev roles available. I know traditionally QA type jobs carry an odd "danger" tag, but test automation is really a different beast. Does anyone have any experience moving from test automation to development? Does the QA stigma exist? The extra $$ would be nice, but not at the expense of my career. I should note that my Master's will be on Systems/parallel programming, so one thought is that I'll get automatic consideraton for development upon completing my Master's. I also work 6hrs/wk doing game development with a friend.

• USB Keyboard not working under windows 7 x64?

  - by Comboo

  I have two usb keyboards, one no-name cheapo thing and an old logitech. When i plug them in to my computer they pop up in device manager as "Unknown device" respective "USB-receiver". Both of them fail to install any drivers, neighter automatically or through windows update. Both keyboards work perfectly on another computer i have with vista 32bit. Can this be one of those cases where a device does not work in 64bit version of windows? I doubt it though since I've never had that problem before with any device and i thought that basic things like keyboards would be kind of failsafe. I don't really know how to start debugging this issue. I've tried all the obvious, rebooting, changing usb-port etc. Are there any generic x64 keyboard drivers you can use? Is there any way to find the manufacturer of the keyboard over usb? There is nothing written on it.

• Automatically Snapshoting AWS instances (or other back up strategy)

  - by user1172468

  I just realized that my aws instance count has risen into the double digits. I'm currently backing portions of my folders and dbs and moving them off to a backup instance. What I think I should be doing is taking a snapshot of the instances (automatically) and persisting them on S3 so I have a running 7 day collection of daily backups. There is a question asking the same thing here, however the answers don't go into depth. So the closest answer seems to be: use a cron job to snapshot the instance. So do I run the cron job on the instance itself? or do I have a micro instance to run these snapshots? Could I get an example script or the command for say a linux flavor? what software must I have installed to get this to run? Thanks.
