Restore audio settings - cannot open mixer: No such file or directory

- by Alfred M.

The internal speaker of my laptop never functionned under Ubuntu. I tried to follow indication on the web and now the jack audio does not work either. The graphic interface for audio management now displays a 'dummy output' instead of the three possible outputs I used to have (one of them was working for the jack output). In a terminal alsamixer raises an error: cannot open mixer: No such file or directory I did try to remove and reinstall alsa-utils but it did not change anything. This happened after a failed atempt to install alsa-driver-linuxant_1.0.23.1_all.deb from here. My sound card seems to be not recognised anymore. After reboot I have no more the sound icon in menu bar the upper right corner. I think I have removed my sound card driver. Indeed, the command sudo lshw -class multimedia indicated audi device as unclaimed. Any idea how I could revert to a better situation (that is jack support and alsa working)? EDIT: The command lspci -nnk | grep -iEA3 audio gives lspci -nnk | grep -iEA3 audio 00:1b.0 Audio device [0403]: Intel Corporation 82801I (ICH9 Family) HD Audio Controller [8086:293e] (rev 03) Subsystem: ASUSTeK Computer Inc.

How to stop Bash appending history

- by Craig

I am having a lot of trouble setting up the terminal history of Bash the way I want. I would like to have no duplicate entries and if I enter a command I want it saved and the duplicates above removed. The problem is the history command shows me it is functioning the way I want however once I log out the duplicates come back again. I believe it is just appending the history to the existing one. I have these lines in my .bashrc file (~/.bashrc) HISTCONTROL=ignoreboth:erasedups shopt -u histappend I have even tried uncommenting shopt but it still appends the history on logout. How can I have the history be exactly how it is before I logout?

EC2 instance store cloning or to ebs via guy management console

- by devnull

I have found similar questions here but the answer are either outdated or are from the command line. The case is this. I have an EC2 instance using instance store (this was the only AMI available for Debian 6 in Ireland). Now through the AWS GUI I can do a snapshot of the instance volume and/or even create a volume. But an image made from the snapshot doesn't boot. What is the best solution to either clone an EC2 instance that uses instance store OR from the created snapshot of the instance store to launch a new EBS instance (identical clone) FROM the gui aws management console and not command line ? Before turning this down consider that there is not similar question on how to do it via the aws management console. hint can't be done is not an appropriate answer. As you can create a snapshot of the instance store backed instance and/or a volume and create an AMI from that snapshot.

How to power off a hard drive to essentially "hot swap"

- by Brandon

I'm looking for either freeware or the programming basics to power off/on a hard drive. Mounting and unmounting a hard drive is simple enough just using the command prompt in Windows XP. Now I need to be able to power down the hard drive so it will not become damaged when being unplugged. I would prefer this to be a simple doable in the command prompt, a simple script, or at worst C++/C#. Freeware that does this exact requirement would also do the job. This script/program will run on Windows XP with .NET 2.0 SP1.

controlling an object through another object ?

- by Stefano Borini

Today I've seen the following pattern: you have an object A and an object B. Object B accepts a pointer to A at its constructor. Once B is created, there's a method B.doCalc() that performs a calculation (internally using A's information). The result is obtained with method B.getResult(). In order to perform another calculation, A is modified, and B.doCalc() is called again. What is your opinion on this choice ? I would have designed it differently, but I want to hear your voice. Edit : note that my main objection is to modify A to have a different result from B, without touching B. Although similar, I think that just this discipline expresses a much better feeling of what's going on. Instead of a = new A a.whatever = 5 b = new B(a) b.doCalc() res = b.getResult() a.whatever = 6 b.doCalc() res = b.getResult() You get the a pointer object from b itself. a = new A a.whatever = 5 b = new B(a) b.doCalc() res = b.getResult() a = b.getAPointer() a.whatever = 6 b.doCalc() res = b.getResult() because it makes more explicit the fact that a is taken from b and then modified. I still don't like it, though...

How to get both PIPESTATUS and output in bash script

- by Mustafa Serdar Sanli

I'm trying to get last modification date of a file with this command TM_LOCAL=`ls -l --time-style=long-iso ~/.vimrc | awk '{ print $6" "$7 }'` TM_LOCAL has value like "2012-05-16 23:18" after execution of this line I'd also like to check PIPESTATUS to see if there was an error. For example if file does not exists, ls returns 2. But $? has value 0 as it has the return value of awk. If I run this command alone, I can check the return value of ls by looking at ${PIPESTATUS[0]} ls -l --time-style=long-iso ~/.vimrc | awk '{ print $6" "$7 }' But $PIPESTATUS does not work as I've expected if I assign the output to a variable as in the first example. In this case, $PIPESTATUS array has only 1 element which is same as $? So, the question is, how can I get both $PIPESTATUS and assign the output to a variable at the same time?

Facebook Stories for Retailers

- by David Dorf

Getting people to "like" a brand is important because it opens the door to a possible B2C relationship. Once a person likes that brand, the brand can post to their newsfeed with promotions, announcements, and surveys. At least for me, I "hide" the noisy brands and just monitor the ones that keep posts under 4 times a week. I see lots of people, especially with fashion brands, comment on postings at which point the posting is seen by their network. A metric I've heard (but not verified) is that for every person that comments, ten of their friends see the original posting. That's a pretty cheap way to communicate to potential customers in a viral way. Over at mainstreet.com they compiled the a list of the top liked retailers on Facebook as of Feb 1, 2011. They are listed below: 19,414,892 Starbucks 11,302,939 Victoria's Secret 7,925,184 Zara 7,032,398 McDonald's 6,117,222 H&M 5,400,586 Taco Bell 4,665,760 Subway 4,494,849 Lacoste 4,185,570 Hollister 3,973,181 Forever 21 So I guess the public likes their fast-food and fashion. To take this to the next level, Facebook is now displaying Sponsored Stories, which I saw for the first time on my page this weekend. I found this picture at the Wall Blog that depicits Sponsored Stories very well. Over on the right-hand column of a person's page, where they see advertisements and such, Facebook will post stories involving their network of friends and their interaction with sponsored brands. Now their "likes" can suddenly become your ads. "Jessica and Philip like Starbucks. What are you waiting for?" This is another great way to take messages viral by accessing social graphs. As usual there will be a certain level of outcry from privacy advocates, but given the other more iniquitous issues, I believe this will fall by the wayside. Retailers should consider using Sponsored Stories to increase their Likes, and thus increase their voice in the social world.

Problem with XeTeX (LaTeX) and system fonts

- by mghg

I have started to use an enterprise specific class for LaTeX, but have got a problem with usage system fonts in Ubuntu. The class uses the fontspec package, I have therefore been instructed to use XeTeX (i.e. the command xelatex instead of latex or pdflatex). However, the command xelatex testfile.tex results in the following message: ! Package xkeyval Error: `TeX' undefined in families `Ligatures'. See the xkeyval package documentation for explanation. Type H <return> for immediate help. ... l.61 \newfontfamily\headfont{Arial} ? The class has previously been used on Mac and Windows and the font setup is as follows: \newfontfamily\headfont{Arial} \newcommand\texthead[1]{\headfont #1} \setromanfont{Georgia} \setmainfont{Georgia} \setsansfont[Scale=MatchLowercase]{Verdana} It has been suggested that since XeTeX makes use of system fonts and the class file has worked flawlessly on Mac and Windows, the problem might be that Arial is not a name used in Ubuntu. I have tried to exchange Arial with Ubuntu Light in the setup code above, but that have not been any improvement. Any suggestions please on how to move forward?

Netsh commands not working on remote computer

- by Mike Christiansen

Hello, At work, we are in the process of migrating over 200 computers from static IPs to DHCP. The DHCP server is configured. My biggest hurdle is physically going to every single computer in the area and configuring them all for DHCP. I am trying to use netsh to accomplish this. However, I cannot even seem to set one computer to DHCP remotely. The command I am trying is: netsh -r COMPUTERNAME interface ip set address name="Local Area Connection" source=dhcp netsh -r COMPUTERNAME interface ip set dns name="Local Area Connection" source=dhcp This results in the error The following command was not found: interface ip set address "name=Local Area Connection" source=dhcp. Any ideas?

How can I hard reset a USB device?

- by Cory

I have a USB device (a modem) that is really finicky. Sometimes it works fine, but other times it refuses to connect. The only solution I have found to fix it once it gets into a bad state is to physically unplug the device and plug it back in. However, I don't always have physical access to the machine it is plugged in on, so I'm looking for a way to do this through the command line. This post suggests running: sudo modprobe -w -r usb_storage; sudo modprobe usb_storage However I get an "unknown option -w" output. This slightly modified command: sudo modprobe -r usb_storage Fails with the message FATAL: Module usb_storage is in use. If I try to kill -9 the processes marked [usb-storage] before running they refuse to die (I think because they are deeply tied to the kernel). Anyone know of a way to do this? NOTE: I cross-posted this on superuser.com as I didn't know which was more appropriate. I will delete and/or link whichever one is answered first.

OSB and Ubuntu 10.04 - Too Many Open Files

- by jeff.x.davies

When installing the latest Oracle Service Bus (11gR1PS3) onto my Ubuntu 10.04 system, the Eclipse IDE was complaining about there being too many open files. The Oracle Service Bus and the Oracle Enterprise Pack for Eclipse (aka OEPE) do make use of ALOT of files. By default, Ubuntu will restrict each user to 1024 open files. A much more realistic number for OSB development is 4096. Changing the file limit in Ubuntu is fairly simple (if arcane). You will need to modify two different files and then restart your server. First, you need to modify the limits.conf file as the root user. Open a terminal window and enter the following command: sudo gedit /etc/security/limits.conf Add the following 2 lines to the file. The asterisk simply means that the rule will apply to all users. * soft nofile 4096 * hard nofile 4096 Save your changes and close gedit. The second file to change is the common-session file. Use the following command: sudo gedit /etc/pam.d/common-session Add the following line: session required pam_limits.so Save the file and exit gedit. Restart your machine. You shouldn't have any more problems with too many open files anymore.

Can TP-Link router make phone calls?

- by Umair Ashraf

I have a TP-Link router with DSL service provided by a local company which serves it over the landline phone. My landline cord is plugged into an ethernet router which is then plugged into TP-Link wireless router. I can access internet with this wireless router all over my home with all computers. Landline Cord [into] Ethernet Router [into] TP-Link Wireless Router [air] Computers I would add that landline cord is also into a phone device which I use to make calls and that's not cordless. Now I am accessing internet via WiFi on my laptop and want to ask if is this possible to make landline calls via this same computer I am surfing internet through? What I am asking it to a dial-up via TP-Link router that goes through landline. You see the landline cord is the actual data gateway and is also used to make calls. So it can simultaneously send Data and Voice over the same wire.

Odd behavior on Shift-{Esc,Fx}

- by ??????? ???????????

Sometimes, when changing between the modes in Vim, I forget to take my finger off the Shift key. This innocent mistake is probably part of the luggage carried over from other terminals, but I have never seen my input treated this way. After changing from command mode to input mode, if I hit the Esc key while the Shift key is down, Vim will display <9b (Control Sequence Introducer) instead of switching to the command mode. At least two work-arounds to this intended behavior are available on the mintty site (faq, issue). " Avoiding escape timeout issues in vim :let &t_ti.="\e[?7727h" :let &t_te.="\e[?7727l" :noremap <EscO[ <Esc :noremap! <EscO[ <Esc " Remap escape :imap <special <CSI <ESC My question is about the syntax and the meaning of the first solution. From the looks of it, it seems like t_ti is being assigned a literal value, but I'm not sure why the "c address-of" operator is required. I'm also not sure why there are two noremap statements.

Specify a custom dictionary for FxCop and Visual Studio source analysis

- by Marko Apfel

Renaming the default custom dictionary from CustomDictionary.xml to an other name – for instance FxCop.CustomDictionary.xml needs some additional changes to work in involved applications. Visual Studio Team System code analysis For Visual Studio Team System code analysis this file should be added as a link to all projects and setted to be the Build Action CodeAnalysisDirectory. Build target In a build target the command line tool FxCopCmd should be called with the /dictionary parameter: <Target Name="FxCop"> <Exec Command=""$(ProjectDir)..\..\build\FxCop\FxCopCmd.exe" /file:"$(TargetPath)" /project:"$(ProjectDir)..\EsriDE.SfgPraxair.FxCop" /directory:"$(ProjectDir)..\..\lib\Esri.ArcGIS" /directory:"$(ProjectDir)..\..\lib\Microsoft" /dictionary:"$(ProjectDir)..\FxCop.CustomDictionary.xml" /out:"$(OutDir)..\$(ProjectName).FxCopReport.xml" /console /forceoutput /ignoregeneratedcode"> </Exec> <Message Text="FxCop finished." /> </Target> FxCop-GUI (standalone application) In FxCop-GUI is no option to specify an own file name – but you could add a hint in the FxCop project file. Open your this file and look for the line: <CustomDictionaries SearchFxCopDir="True" SearchUserProfile="True" SearchProjectDir="True" /> Then change it to: <CustomDictionaries SearchFxCopDir="True" SearchUserProfile="True" SearchProjectDir="True"> <CustomDictionary Path="FxCop.CustomDictionary.xml"/> </CustomDictionaries> Ready :-)

How to design a scriptable communication emulator?

- by Hawk

Requirement: We need a tool that simulates a hardware device that communicates via RS232 or TCP/IP to allow us to test our main application which will communicate with the device. Current flow: User loads script Parse script into commands User runs script Execute commands Script / commands (simplified for discussion): Connect RS232 = RS232ConnectCommand Connect TCP/IP = TcpIpConnectCommand Send data = SendCommand Receive data = ReceiveCommand Disconnect = DisconnectCommand All commands implement the ICommand interface. The command runner simply executes a sequence of ICommand implementations sequentially thus ICommand must have an Execute exposure, pseudo code: void Execute(ICommunicator context) The Execute method takes a context argument which allows the command implementations to execute what they need to do. For instance SendCommand will call context.Send, etc. The problem RS232ConnectCommand and TcpIpConnectCommand needs to instantiate the context to be used by subsequent commands. How do you handle this elegantly? Solution 1: Change ICommand Execute method to: ICommunicator Execute(ICommunicator context) While it will work it seems like a code smell. All commands now need to return the context which for all commands except the connection ones will be the same context that is passed in. Solution 2: Create an ICommunicatorWrapper (ICommunicationBroker?) which follows the decorator pattern and decorates ICommunicator. It introduces a new exposure: void SetCommunicator(ICommunicator communicator) And ICommand is changed to use the wrapper: void Execute(ICommunicationWrapper context) Seems like a cleaner solution. Question Is this a good design? Am I on the right track?

Workaround: build FBX in XNA raise OutOfMemoryException

If you try to add large FBX 3D model to the XNA project, and build it, you can get an OutOfMemoryException build error like following: Error 1 Building content threw OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown. at System.Collections.Generic.List`1.set_Capacity(Int32 value) at System.Collections.Generic.List`1.EnsureCapacity(Int32 min) at System.Collections.Generic.List`1.InsertRange(Int32 index, IEnumerable`1 collection) at Microsoft.Xna.Framework.Content.Pipeline.Graphics.VertexChannel`1.InsertRange(Int32 index, Int32 count) at Microsoft.Xna.Framework.Content.Pipeline.Graphics.VertexContent.InsertRange(Int32 index, IEnumerable`1 positionIndexCollection) at Microsoft.Xna.Framework.Content.Pipeline.Graphics.MeshBuilder.AddTriangleVertex(Int32 indexIntoVertexCollection) at Microsoft.Xna.Framework.Content.Pipeline.MeshConverter.FillNodeWithInfoFromMesh(KFbxNode* fbxNode, String name, KFbxGeometryConverter* geometryConverter) at Microsoft.Xna.Framework.Content.Pipeline.FbxImporter.ProcessInformationInNode(KFbxNode* fbxNode, String name, Boolean* partOfMainSkeleton, Boolean* warnIfBoneButNotChild) at Microsoft.Xna.Framework.Content.Pipeline.FbxImporter.ProcessNode(ValueType parentAbsoluteTransform, NodeContent potentialParent, KFbxNode* fbxNode, Boolean partOfMainSkeleton, Boolean warnIfBoneButNotChild) at Microsoft.Xna.Framework.Content.Pipeline.FbxImporter.ProcessNode(ValueType parentAbsoluteTransform, NodeContent potentialParent, KFbxNode* fbxNode, Boolean partOfMainSkeleton, Boolean warnIfBoneButNotChild) at Microsoft.Xna.Framework.Content.Pipeline.FbxImporter.Import(String filename, ContentImporterContext context) at Microsoft.Xna.Framework.Content.Pipeline.ContentImporter`1.Microsoft.Xna.Framework.Content.Pipeline.IContentImporter.Import(String filename, ContentImporterContext context) //additional calls here … My desktop PC have 8Gb RAM, and Visual Studio’s process devenv.exe use under 2Gb of it while build process (about 3.5-4Gb of RAM is always free).

OS on my PC is Win x64, so I “charge” devenv.exe by using editbin.exe utility – in the VS Command prompt I run following: editbin "C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\devenv.exe" /LARGEADDRESSAWARE This command edits the image to indicate that the application can handle addresses larger than 2 gigabytes.

P.S.: although now you can build a bigger files, than usual, keep in mind, that XNA have some restrictions on vertex buffer size etc., depend on your current XNA project profile (Reach or HiDef). And if your model’s vertexbuffer size more than 64Mb (with Reach profile), that model can’t be built and raise an error.

ASUS EPC 1015CX won't boot with display after installing additional drivers

- by Dinesh

I have a ASUS EPC 1015CX with Ubuntu 12.04 LTS installed using wubi alongside Windows 7. It worked perfectly after installing except that the supported screen resolution was only 800*600 instead of 1024*600. The specifications of the 1015CX device can be found here I tried installing additional drivers which was Broadcom for wireless and Cedarview-drm. By this time there was no display coming up after the boot. I could hear a voice and then the letters I typed got pronounced correctly. So, I guessed the issue has to be with the graphic terminal. I tried repair broken packages in the menu and booted and the display is now at 1024*600. But, if I restart normally the problem continues like before. As per what I found out after searching, I again opened additional drivers and installed Cedarview-graphics-driver. I tried restarting hoping it will work. But again, the result was same. There was no display but the system was working. I did more searching and followed the instructions found here. But still the result was same. I am keen to switch to linux from windows after hearing and learning great things about it. I know this community is good and always helping. I wanted to thank you all for the help in advance. Please let me know what I am doing wrong and help me to switch to linux from this same old windows.

Removing specific part of filename (what's after the second dash) for all files in a folder

- by Bodo

I use the command line utility youtube-dl to download videos from YouTube and make mp3s from them with avconv. I'm doing this under Ubuntu 14.04 and very happy with it. The utility downloads the files and saves them with the following name scheme: TITLE(artist-track)-ID.mp3 So an actual filename looks like: EPIC RAP BATTLE of MANLINESS-_EzDRpkfaO4.mp3 Some other file names in the folder look like: EPIC RAP BATTLE of MANLINESS-_EzDRpkfaO4.mp3 Martin Garrix - Animals (Official Video)-gCYcHz2k5x0.mp3 Stromae - Papaoutai-oiKj0Z_Xnjc.mp3 At first, this was no problem. It didn't bother me while listening to my music in Rhytmbox. But when moving to phone or other devices it is pretty confusing to see a so long name, and some players, like the Samsung ones, treat that last part (id after second dash) of the name as Album or something. I'd like to create a bash script that removes what's after the second dash in the name for all files, so it'll make them like this: From: Martin Garrix - Animals (Official Video)-gCYcHz2k5x0.mp3 To: Martin Garrix - Animals (Official Video).mp3 Is it also possible to instruct youtube-dl to exclude the ID from now on? I am currently downloading with the command: youtube-dl --extract-audio --audio-quality 0 --audio-format mp3 URL

What is the easiest and cleanest way to create a chrooted SFTP on Centos 5.4?

- by benjisail

Hi, I would like to setup a SFTP with chroot (or equivalent) login to my Centos 5.4 server in a clean way. By clean way I mean by using only the YUM command if possible and with something easy to maintain and easy to extend (for example an easy way to add an extra SFTP user). The problem with CentOS 5.4 is that OpenSSH is at version 4.3 in the repository so it is not possible to use the built in chroot capabilities of OpenSSH 4.8+. Installing RSSH required to create manually a chrooted directory which don't seems easy to maintain to me. MySecureShell is an other solution but it require an higher version of openSSL than the one which is in the repository. I know that I could install manually an higher version of OpenSSH but I would lose all the advantage of the Yum command and it could become tricky to maintain if I want to do some updates in the futur... Do you have an easy and clean way to setup a chrooted SFTP login on a centOS 5.4 server? Thanks!
