• Code review vs pair programming

  - by mericano1

  I was wondering what is the general idea about code review and pair programming. I do have my own opinion but I'd like to hear from somebody else as well. Here are a few questions, please give me your opinion even on some of the point First of all are you aware of way to measure the effectiveness of this practices? Do you think that if you pair program, code reviews are not necessary or it's still good to have them both? Do you think anybody can do code review or maybe is better done by seniors only? In terms of productivity do you think it suffers from pairing all the times or you will eventually get in back in the long run? Thanks!

• Software Center doesn't ask for a password anymore

  - by Jeff

  So, out of the blue, software-center stopped asking me for a password. It just runs, and then turns grey. Works fine as root, or with sudo. While investigating, I found out about polkit (new to me), and looked at the policies, which seem fine. Looking under localauthority, however, showed that while the sub-directories (10-, 20-, 30-, 50-, 90-) are there, there aren't any files under those. Is that my problem? Should there be a file in the 50-local.d? Or am I still looking in the wrong place for my problem? I looked for similar questions and looked at the answers, but they don't really help any. One other thing, I'm not sure it's related but seemed to happen about the same time: The Dash Home only shows items for recent files and downloads. Nothing anywhere else anymore.

• Microsoft Office 2013 Takes New Approach

  You can check out an article from Computerworld for a good look at the questions and answers about the new software. For instance, you've probably noticed that I'm not giving the full name. That's because Microsoft seems to be using several names. If you go the traditional route and pay the one-time upfront fee for the shrink-wrapped edition, it's Office 2013. There's also a tablet version called Office Home and Student 2013 RT - but that won't include the iPad, or at least not at first. The consumer preview, which I'll be linking to in a minute, is dubbed Office 365 Home Premium. There ...

• Share on Facebook does not show thumbnail images

  - by matt74tm

  I have a PHP application which has a "Share on Facebook" button that, On the development server shows the thumbnail images correctly and allows the user to select between them On the live server, it does NOT show the thumbnail images at all. The relevant portion of the .htaccess file is: # Set up caching on media files for 2 days <FilesMatch "\.(gif|jpg|jpeg|png|flv)$"> ExpiresDefault A172800 Header append Cache-Control "public" </FilesMatch> I'm using the exact same set of php files and .htaccess, but the server configuration is different. What could be causing this? Note that the text appears fine. Edit1 We are also doing some URL rewriting related to images in the .htaccess (on both servers): ... RewriteRule ^.*/content/image/(.*)$ content/image/$1 [L] ... RewriteRule ^.*/images/(.*)$ images/$1 [L] ... Would that be somehow making a difference? Images appear fine all throughout the site. (I posted this question earlier as http://stackoverflow.com/questions/4142597/share-on-facebook-does-not-show-thumbnail-images) )

• DVC101 Video Capture Device on USB hub - Ubuntu Server 12.04

  - by John

  I have a Dell Inspiron 8600 laptop I use as a media server/video capture system. It only has 2 USB ports and I have a total of 3 devices I need to connect. The DVC101 works perfectly while plugged directly into the USB port in back of the laptop. Unfortunately it does not get recognized when plugged into a passive or powered USB hub. Questions: Is there something I am missing on the Ubuntu side? Something I need to do that will allow the device to be recognized through the hub? If not, will the extra USB ports on a dell laptop dock (port replicator) act the same as the aftermarket hubs? I know this one is off topic of Ubuntu but any input appreciated.

• Checking whether the user input is a str in Python [migrated]

  - by Sahil Babbar

  I checked various questions on Stack Overflow but one thing every logic lacks. Let me demonstrate using Python: while True: user_input = raw_input() if type(user_input) == str: print 'ERROR' else: print 'BINGO' Also, we cannot use input() in place of raw_input() as it gives the error:Traceback (most recent call last): File ".\test.py", line 3, in <module> user_input = int(input()) File "<string>", line 1, in <module> NameError: name 'asdf' is not defined The problem here is that raw_input converts the user input into string so it always prints 'ERROR' and if I change the second line to user_input = int(raw_input) then, it gives an error: Traceback (most recent call last): File ".\test.py", line 3, in <module> user_input = int(raw_input()) ValueError: invalid literal for int() with base 10: 'asdf' I tried this with try and except but it shall work fine to check integer but not a string. I feel that this question may be marked as a duplicate but I think that this query is important, if logically taken.

• April 25th Online Forum -- Oracle Solaris 11: What's New Since the Launch

  - by Larry Wake

  It's been a few months since we released Oracle Solaris 11, so we thought it was time to check in and let you know how things are going. On April 25th, at 9:00 PT, we'll host an online forum, featuring Markus Flierl, the VP for Solaris core engineering, as well as engineers, customers and partners. During the forum, Markus and his crew will give an update on the release, recap Oracle's OS strategy, and give you a peek at what the engineers are working on for future updates. I think one of the more interesting parts of this event will be the chance for some of our customers to share why they've moved to Oracle Solaris 11 and what benefits it has already given them.  We'll also have an online chat, so you can ask Solaris engineers any questions about what you've heard, or other thoughts you've had.  It should be a worthwhile event -- hope you can join us. Online Forum: Oracle Solaris 11: What’s New Since the LaunchApril 25th 9:00 a.m. PDT – 11:30 a.m. PDTRegister today!

• Why I LOVE Dell

  - by Robert May

  We recently ordered a laptop for an employee.  It was delivered yesterday and we realized it had no web cam and wasn’t the 1080p resolution.  He wasn’t happy. So, this morning, I sent an e-mail to our rep and asked him what we could do.  Within an hour or two, he called me, arranged a replacement laptop with the corrected specs, set up a return and had everything arranged and charged us only for the difference.  No pain, no silly questions.  We won’t loose use of the laptop either.  The return and the new laptop will overlap so that we can just pack up the old laptop in the box of the new one, slap some labels on and away we go. This has been my experience with Dell over the past 10 years.  Their corporate service has always been fantastic, and it’s made me a huge fan.  Keep up the good work, Dell! Technorati Tags: Dell

• Windows Phone 8 detected as mass storage

  - by legends2k

  From version 8 onwards Windows Phone supports MTP (media transfer protocol) to transfer audio and I thought I could use Rhythmbox to upload music onto my device. Thing is Rhythmbox doesn't display the device under Devices pane (there's no Device pane for that matter). I searched other questions here and tried out installing mtp-tools, mtpfs and also tried gMTP, which doesn't seem to detect the device as a portable player. I see that the device's icon looks like a Camera in dash bar and when I see the address location, it shows gphoto2://[usb:002,013]/, which makes me doubt that it's detected as a camera or as a mass storage device. /.gvfs/gphoto2 mount on usb%3A002,003 is where the actual mount is. What do I do to fix this? I tried creating .is_audio_player too.

• Turning my mobile boardband into Wifi with my laptop using Kubuntu 12.04 to use it in my desktop PC

  - by Suhail cholassery

  Its been 3 or 4 months since I started using 12.04. What I want to do is very clear: Turn my mobile broadband connection into Wifi connection with my laptop using Kubuntu 12.04 to use it in my desktop PC. I browsed through most of the questions related to this (ad- hoc connections, bridging mobile broadband with Wifi, etc). I also read the ICS article, but I found those too difficult to digest. I hope that there is some other way to do this. I request you to give me a practical and applicable answer . I am not trying duplicate any other existing question.

• Options for secure git -repo hosting?

  - by hhh

  I need a secure git -repo host, either by third-party or by myself. I am not sure how so outlining some ideas. Please, answer how you manage git -repos securely -- do you use some service or do you use only your 'legs' -approach? Afaik Bitbucket.org and Github.com are missing Gmail -style second-verification. Now I need this kind of login-system with password and mobile-phone to access the administration things in the git -hosting or ability to disable this kind of access without private -key. Host it oneself (not sure about details) other? Perhaps related http://stackoverflow.com/questions/11007679/how-can-i-host-git-repositories-and-manage-my-content-hosting-myself

• Launcher disappears when Focuswriter is minimized

  - by Andreas

  This bug has to do with the integration of the full-screen writing app Focuswriter within Unity. It appeared before I upgraded from Ubuntu 12.04 to 12.10 - probably caused by a an automatically upgraded change that persist in 12.10: When I minimize Focuswriter after it has been in full-screen mode the launcher is invisible - instead of seeing it I just see a rectangle the color of my desktop background where it should have been. The launcher becomes visible if I click the area once but then I'm likely to hit an icon and unwillingly open a program. I've reported the bug to the developer of the program here: https://github.com/gottcode/focuswriter/issues/101 He has labeled the bug "upstream" saying that the bug is can only be fixed in Unity. My questions are: 1) does anyone (perhaps experiencing problems with other full-screen programs) have a solution or workaround so the launcher won't disappear? 2) where can I file a bug report for this problem?

• When do one give up on programming challenges to look at the solutions?

  - by snowpolar

  Recently, I have been trying to learn programming and improve my ability in writing method level code through practices on websites such as Codingbat.com However in the recent weeks I have been stuck for weeks at the last 2-3 questions of String-2/Array-2 and early String/Array-3 problems. It feels really tempting for me to give up and google online for the solutions, but I'm afraid that by doing so I may end up not improving my ability at all. I wonder if this is common and when faced with such situations how long do 1 wait before giving up to look at the solutions or to continue spending more weeks on trying to solve the problems by yourself? How do 1 really engage in effective deliberate practice to improve programming ability and attain the necessary problem solving techniques? Any formal techniques available to tackle the never seen before problems?

• Write data to SQL Server directly from BizTalk or use external service?

  - by dlongest

  An external source will be sending us XML data that BizTalk will pick up and transform into an internal schema. We need this data to be loaded into a SQL Server database as we're going to expose some of the data to our web front-end via a custom WCF service. The question is: what is the recommended approach for doing something like this? Options we're considering are having BizTalk write to the database directly or having BizTalk call a custom WCF service which would handle the save operation. Another briefly considered idea was having BizTalk write to an MSMQ and have a custom service pull from there and store it in the database. What are some of the guidelines or questions that should be asked in assessing these options? There are concerns related to overhead from calling the extra service, duplication of efforts if the schema is modified in the future (which it will be to some extent), and simply the best way to design within a service-oriented architecture that we're struggling with.

• Question about server usage, big community platform

  - by Json

  I’m working on a community platform writen in PHP, MySQL. I have some questions about the server usage maybe someone can help me out. The community is based on JQuery with many ajax requests to update content. It makes 5 - 10 AJAX(Json, GET, POST) requests every 5 seconds, the requests fetch user data like user notifications and messages by doing mySQL queries. I wonder how a server will handle this when there are for more than 5000 users online. Then it will be 50.000 requests every 5 seconds, what kind of server you need to handle this? Or maybe even more, when there are 15.000 users online, 150.000 requests every 5 seconds. My webserver have the following specs. Xeon Quad 2048MB 5000GB traffic Will it be good enough, and for how many users? Anyone can help me out or know where to find such information, like make a calculation?

• How do I increase the touchpad sensitivity on Acer Aspire One 532h?

  - by Yossi Farjoun

  I got a cheap netbook and put ubuntu on it without even booting into the windows it came with. I am now slightly regretting it since the trackpad is very annoying, it only registers when I press quite hard on it, and even then the motion is so slow that I must drag me poor finger 3 times to get the pointer to move up or down that tiny screen. OK. enough rant. now business: I went into the setting and increase sensitivity and acceleration to high. No difference. the behaviour did not change at all. So now my questions are: Is this a hardware problem? Is there a program I can run to see what input the trackpad is receiving? so I know if it can, in theory, read the light touch and not only the heavy, sandpaper-your-fingertips-off touch? is there some manual setting that the system might not be setting correctly and which I could change from the terminal?

• AGPL License - does it apply in this scenario?

  - by user1645310

  There is an AGPLv3 based software (Client) that makes web service calls (using SOAP) to another software (Server - commercial, cloud based). There is no common code or any connection whatsoever between these two except for the web service calls being made. My questions - Does the Server need to be AGPL too? I guess not - but would like to confirm. Let us say the end point URL for the Server can be configured on the Client side (by editing an XML file) to connect it to different Servers (again, there is no connection other than the webservice calls being made) does it require any of these Servers being AGPL? Are there any issues in running the Client as a DLL that is loaded by other commercial applications on users' desktops? Does it require these other applications also to be AGPL?

• What tools exist to report bugs

  - by Luis Alvarado

  As of today I only knew about ubuntu-bug which I could use to report bugs about a specific program. But now I learned about apport-collect and apport-bug which basically are: apport-bug - Reports problems to launchpad using Apport to collect a lot of information about your system to help the developers fix the problem and avoid unnecessary questions and answers. apport-collect - Works as apport-bug but it send the information to an already existing bug report. In my case it was apport-collect 1060268 Thanks to Brad Figg in Launchpad. Are there any other tools to report bugs?
