• Assign programs permanently to different sound-outputs in Pulseaudio?

  - by Mood

  I want to assign Skype input and output to my USB-headset while the rest of my laptop uses the internal sound-card. This is an easy task with PulseAudio Volume control (pavucontrol). The only problem I have is every time a call is made I manually have to set the output and input for Skype to my USB-device . When I hang up, Skype disappears from Volume Control. It reappears again with the next call only this time the default sound-card is selected again. It shouldn’t be hard to let PulseAudio look or the USB-headset is connected when Skype audio comes is before selecting the default. The way to do it is obvious not through Volume Control.

• How serious/common are wordpress updating issues

  - by gyaani_guy

  I am currently deciding between a CMS (joomla OR wordpress )to dive deep into. I think I would go for wordpress, but the only thing thats holding me back are any potential issues with updating wordpress- that updating wordpress can break plugins, but is necessary because of security issues. How drastic are the changes in wordpress? say over a period of 2-3 years? from the perspective of someone intending to dive head first in its code. Should I fear regular updates breaking stuff ? Thanks

• How do you balance the speed of Sprints with the customer's conservative adoption schedule?

  - by Cheeso

  I'd prefer to have sprints that last 3-4 weeks, but customers don't want to adopt new feature/function every 3-4 weeks. Existing customers are conservative and, once we meet their minimum bar for features and capabilities, they like to remain on a stable release for much longer than 4 weeks. Even a 3-month cycle would be pushing it for them. On the other hand, newer customers tend to have more feature requests, and are willing to follow sprints. But this willingness dissipates after we've met their bar. How do you balance the need for rapid sprints with the customer's conservative view of application change? I'm particularly interested in SaaS scenarios.

• What Application Indicators are available?

  - by user8592

  I installed Ubuntu 11.04 on one of my systems and I am using the Unity interface. Unity is working quite well so far but I really miss panel applets for net speed, cpu temp, and system monitor. These applets are useful for viewing quick info. Unlike 10.10, there is no other way to get this info onto the panel or unity launcher. There are solutions like screenlets and conky but they don't feel appropriate for a clean desktop look. If you know one then please list out any third party indicators with links so that they can be found.

• apt-get not recognizing downloaded archives

  - by meteors

  I installed Ubuntu Gnome 13.10. I previously had Ubuntu Gnome 13.04 and had all the archives in the /var/cache/apt/archives/ stored to a removable disk. After installing 13.10 I copied all my archives to the above mentioned path. When I run apt-get install it tries to fetch the archives although I have the archives. Also if instead of apt-get install if I try to install individual .deb files using dpkg -i everything runs fine. These are the permissions of files: How do I fix this. Previously copying archives like this worked fine and downloading duplicates the files.

• Telecommuting with a foreign employer as a permanent job

  - by grabah

  Does anyone have any experience in telecommuting (working at home) for a company based in some foreign country? By this I don't mean working on some contracted job, but more or less permanent job. Is this even possible, what are options for payment, and can you expect to be paid by usual rates for that country or significantly less? Is there any working hours control, or as long as you deliver on time it's all good.

• Tools to diagnose Ubuntu problems

  - by Luis Alvarado

  Over time a user will have several problems with Ubuntu as any other OS in the world. What tools and terminal commands exist in Ubuntu to help diagnose how the problem occurred and help solve it if it can be done. Problems like: Ubuntu Freezes after X time or when using Y app Ubuntu rebooted/hibernated/suspended all by itself Ubuntu not showing video or video has problems Ubuntu not making any sound or sound has problems Ubuntu not reading X drive (Pen drive, Internal Drive, External Drive...) Ubuntu slow Ubuntu not working with X hardware when connected Ubuntu network problem Normally there is a couple of GUI tools or Terminal commands that Ubuntu experts typically mention first to use to do a first diagnosis of this. What GUI tools (in case the problem is not related to video or limits the user from using the GUI) and Terminal commands (In case GUI is not working) can a user use to diagnose and help himself to how to find/fix the problem.

• Application for taking pretty screenshots (like OS X does)

  - by Oli

  I've been building a website for a guy who uses Mac OS X and occasionally he sends me screenshots of bugs. They come out looking like this: This is fairly typical of Mac screenshots. You get the window decorations, the shadow from the window and a white or transparent background (not the desktop wallpaper -- I've checked). Compare this to an Ubuntu window-shot (Alt+Print screen): It's impossible to keep a straight face and say the Ubuntu one anywhere near as elegant. My question is: Is there an application that can do this in Ubuntu? Edit: Follow up: Is there an application that can do this in one move? Shutter is pretty good but running the plugin for every screenshot is pretty tiresome as it doesn't seem to remember my preference (I want south-shadow and that requires selecting south, then clicking refresh, then save) and it's more clicks than I'd like. Is there a simple way of telling shutter I want south-shadow for all screenshots (except entire desktop and area-selection)?

• Do you use to third party companies to review your company's code?

  - by CodeToGlory

  I am looking to get the following - Basic code review to make sure they follow the guidelines imposed. Security code analysis to make sure there are no loopholes. No performance bottlenecks by doing a load test etc. We have lot of code coming in from third parties and is becoming laborious to manage code reviews and hence looking to see if others employ such practices. I understand that it may be a concern for some and would raise the question "Well, who is going to make sure the agency is doing their job right?" But basically I am just looking for a third party who can hold all vendor code to the same standards.

• Using a random string to authenticate HMAC?

  - by mrwooster

  I am designing a simple webservice and want to use HMAC for authentication to the service. For the purpose of this question we have: a web service at example.com a secret key shared between a user and the server [K] a consumer ID which is known to the user and the server (but is not necessarily secret) [D] a message which we wish to send to the server [M] The standard HMAC implementation would involve using the secret key [K] and the message [M] to create the hash [H], but I am running into issues with this. The message [M] can be quite long and tends to be read from a file. I have found its very difficult to produce a correct hash consistently across multiple operating systems and programming languages because of hidden characters which make it into various file formats. This is of course bad implementation on the client side (100%), but I would like this webservice to be easily accessible and not have trouble with different file formats. I was thinking of an alternative, which would allow the use a short (5-10 char) random string [R] rather than the message for autentication, e.g. H = HMAC(K,R) The user then passes the random string to the server and the server checks the HMAC server side (using random string + shared secret). As far as I can see, this produces the following issues: There is no message integrity - this is ok message integrity is not important for this service A user could re-use the hash with a different message - I can see 2 ways around this Combine the random string with a timestamp so the hash is only valid for a set period of time Only allow each random string to be used once Since the client is in control of the random string, it is easier to look for collisions I should point out that the principle reason for authentication is to implement rate limiting on the API service. There is zero need for message integrity, and its not a big deal if someone can forge a single request (but it is if they can forge a very large number very quickly). I know that the correct answer is to make sure the message [M] is the same on all platforms/languages before hashing it. But, taking that out of the equation, is the above proposal an acceptable 2nd best?

• Will YouTube (or any video hosting service) provide a mp4 link to an uploaded video? [closed]

  - by DoubleJ

  I've looked into a number of video hosting options, but none seem to provide a .mp4 link to your uploaded video, which I require for use in a project using BigVideo.js. The only service I've found to provide this functionality so far is VimeoPro, which I can't afford. Is there any way to do this for free in YouTube? Or, otherwise, are there any other (preferably low- or no-cost) video hosting providers that will provide a .mp4 link?

  Client side template binding in web applications is getting popular with every passing day. More and more libraries are coming up with enhanced support for client side binding. jQuery templates is one very popular mechanism for client side template bindings. The idea with client side template binding is simple. Define the html mark-up with appropriate place holder for data. User template engines like jQuery template to bind the data(JSON formatted data) with the previously defined mark-up.In this...(read more)

• Best strategy to discover a web service in a local network?

  - by Ucodia

  I am currently doing some research for a project. The setup is simple, I have a computer running a service in my home network and any device connected to that same network should be able to discover the service automatically and use it. I have no specific technology requirement whether it is on the server or client side. The client knows about the service definition. Other than that I have no idea what strategy to use, what technology to look at or whether I should go for a SOAP or a HTTP based service. I think going HTTP with REST API is the best for targeting all devices but I am opened to any suggestions. Thanks.

• A Web Service to collect data from local servers every hour

  - by anilerduran

  I'm trying to find a way to collect data from different servers around the world. Here are the details: There is only one single PowerShell script on servers that encrypts data (simple csv file) and sends with preferred method (HTTP/HTTPS Post could be) There is no more control on that servers. Can't install any service, process etc. Just I can configure script to execute every hour. This script also will have encrypted username/password/license key for every server. Script will compress data and send to me with these information. So I need a service (I'm not sure if Web Service is the rigth solution) on the cloud that will help me to: Will get data that is sent from servers using a method. Will authenticate request to recognize sender using license key/username/password and most importantly, Will redirect/send this filecab to my SQL Server on the cloud (Azure). Also it should seperate data according to customer information in license key. So every data for every customer will be stored in dedicated DB/Tables on my SQL All the processes above should be completed automatically. No way for manual steps. Question: A Web Service (SOAP or Restful) is the rigth solution for that?

• Allow non-sudo group to control Upstart job

  - by Angle O'Saxon

  I'm trying to set up an Upstart job to run on system startup, and that can also be started/stopped by members of a group other than sudo. With a previous version, I usedupdate-rc.d and scripts stored in /etc/init.d/ to get this working by adding %Group ALL = NOPASSWD: /etc/init.d/scriptname to my sudoers file, but I can't seem to get an equivalent working for Upstart. I tried adding %Group ALL = NOPASSWD: /sbin/initctl start jobname to the sudoers file, but trying to run the command start jobname produces this error: start: Rejected send message, 1 matched rules; type="method_call", sender=":1.21" (uid=1000 pid=5148 comm="start jobname " interface="com.ubuntu.Upstart0_6.Job" member="Start" error name="(unset)" requested_reply="0" destination="com.ubuntu.Upstart" (uid=0 pid=1 comm="/sbin/init") As near as I can tell, that's a complaint about how my user account isn't given the power to send 'Start' messages in the D-Bus config file for Upstart. I haven't been able to actually find any information on how to edit that file to give a group permission to access a specific service--does such an option exist? Is there a way to edit the Sudoers file so I can run the job without editing the config file? Am I better off just sticking with the previous version?

• Is there an equivalent of RDP?

  - by detly

  The "Desktop Sharing" settings that come installed by default seem to use VNC. VNC is a bit of a bandwidth hog, can only work at the resolution of whatever screen is attached to the host, and mirrors every action on the host. (It also seems to work poorly with compositing, but maybe that's been fixed.) I know about X tunnelling, but that's annoying to use and doesn't always work properly (or, more accurately, some apps don't work properly). Is there any kind of protocol in between the two, similar to RDP used for Windows? Specifically, something that can run at a different resolution to the host screen and is a little lighter on the network? (Ideally, the more the protocol could have in common with RDP, the better.)

• HELP: I Broke Ubuntu By Uninstalling Compiz

  - by tSquirrel

  I'm still getting used to Linux, having come from Windows. I was receiving an error that "compiz" had crashed a few times so I figured I'd uninstall it. sudo apt-get remove compiz sudo apt-get install compiz I logged out then back in, after that, the GUI was totally gone and I have no idea how to get it back or what I need to do to restore the GUI to what it was before I killed poor Compiz. GUI was pretty much unmodified after a fresh install of 14.04 How can I fix it? I'm not even sure how to get to a terminal or anything. The login screen looks normal, but after logging in, it's a totally bare desktop with my backround and a few icons. No Dash, toolbar, etc. Hot Keys don't seem to work either (Super = Dash doesn't work, etc); although I did accidently open "Disk" UI. Not sure how. Please Help! Right now I'm working off my W7 dualboot.

• How to run a program as a service (silent)?

  - by U2ros

  I have a python based server which i start from the terminal. This particular instance of the terminal then gives control to the program, and the program uses it as a kind of logging window, until its closed. Is this normal, or should i somehow try to start the program some other way in which it will simply show as an active process? If i close the terminal from which i started the program, the program dies with it. Thank you

• Should one use a separate database for application data and user data?

  - by trycatch

  I’ve been working on a project for a little while and I’m unsure which is the better architecture. I’m interested in the consensus. The answer to me seems fairly obvious but something about it is digging at me and I can't pick out what. The TL;DR is: how do you handle a program with application data and user data in the same DB which needs to be able to receive updates to the application data periodically? One database for user data and one for application, or both in one? The detailed version is.. if an application has a database which needs to maintain application data AND user data, and the user data all references application data, it feels more natural to me to store them in the same database. But if there exists a need to be able to update the application data within this database periodically, should this be stripped into two databases so that one can simply download the updated application data database file as an update and replace the old one? Or should they remain as one database, and the application data be updated via a script which inserts the new data into the existing database? The second sounds clearly preferable to me... but for some reason just doesn’t feel right, and I can't pick out quite why.

• Should developers be involved in testing phases?

  - by LudoMC

  Hi, we are using a classical V-shaped development process. We then have requirements, architecture, design, implementation, integration tests, system tests and acceptance. Testers are preparing test cases during the first phases of the project. The issue is that, due to resources issues (*), test phases are too long and are often shortened due to time constraints (you know project managers... ;)). So my question is simple: should developers be involved in the tests phases and isn't it too 'dangerous'. I'm afraid it will give the project managers a false feeling of better quality as the work has been done but would the added man.days be of any value? I'm not really confident of developers doing tests (no offense here but we all know it's quite hard to break in a few clicks what you have made in severals days). Thanks for sharing your thoughts. (*) For obscure reasons, increasing the number of testers is not an option as of today. (Just upfront, it's not a duplicate of Should programmers help testers in designing tests? which talks about test preparation and not test execution, where we avoid the implication of developers)

• Calculation of Milestones/Task list

  - by sugar

  My project manager assigned me a task to estimate the development time for an iPad application. Lets assume that I gave estimation of 15 working days. He thought that the number of days where too many and client needed the changes to the application urgently (as in most of cases). So, he told me: "I am going to assign two developer including you and as per my understandings and experience it won't take more than seven working days." Clarifications I was given the task of estimating development time for an individual. How could I be sure that 2 developers are going to finish it within 7 days? (I am new to team & I hardly know the others abilities) Questions Why do most of project managers / team leaders have understandings like: If one developer requires N days, Then two developers would require N/2 days, Do they think something like developer = s/w production machines? Should a team member (developer, not team lead or any higher post) estimate other developers work? I didn't deny anything in the meeting and didn't said, but what should be the appropriate answer to convince them that N/2 formula that they follow is not correct?
