• 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!

• How to restart WiFi interface without rebooting (it drops connection)?

  - by Dima

  I boot into ubuntu and it connects to the Wifi network fine. After about 10-15min the DNS stop resolving any website and a couple of minutes later network-managers tells me that I'm disconnected and tries to reconnect constantly to my router and fails to do it. Upon Ubuntu restart everything works fine for the first 10-15min again. When I boot into Mac OS X everything is fine with the same connection! How do I restart wifi interface? sudo ifdow wlan0 just tells me that wlan0 is not configured and wlan0 doesn't appear in /etc/network/interfaces either, which I find strange.... (unless network-manager is doing it behind my back).

• IP/PORT forward requests to another server

  - by DT.DTDG

  I have the following listening PORT:IP set up on my UBuntu server. 12.345.67.890:3636 It receives requests perfectly, however, I would now like to forward any requests to that IP:PORT to another IP:PORT, i.e.: 09.876.54.321:3636 Essentially I want to do a request forward 12.345.67.890:3636 -> 09.876.54.321:3636. How can I go about it in Terminal and if I wanted to change it back how can I go about that too? Is there also a way to test that the data is forwarding and it is setup properly? Thanks! Edit: Can I just do as follows, just wondering how I would go about testing it and how I could disable it? sysctl net.ipv4.ip_forward=1 iptables -t nat -A PREROUTING -p tcp --dport 3636 -j DNAT --to-destination 09.876.54.321:3636 iptables -t nat -A POSTROUTING -j MASQUERADE

• Can someone help me remove/fix ubuntu?

  - by user286152

  I'm very new to ubuntu for starters. Whenever I turn my computer on, it opens to the GNU Grub terminal. It says it supports minimal Bash-Like line editing (I have no idea what this means). To work-around this, I used "exit -ubuntu", this then takes me to a separate page which I selected the Windows Boot Manager and click on the Windows 8.1 icon which makes my Windows 8 load normally. If I click on the other icon, being the ubuntu one, I get put back at the GNU Grub terminal and thats it. If someone could help me either remove ubuntu or repair it so that I can load it again, I would appreciate it. I had installed the most recent ubuntu version. Any other required information to assist I can provide. Thank you.

• How-To: AutoVue Bug Status Tracking & Email Notifications

  - by Graham McKendry

  I’ve posted a number of different Support process-related and tool-related blog entries over the past few years, and one common question I received back from various customers and partners is “How can I easily track AutoVue bugs & enhancements for status updates?” The capability to track bug status through the My Oracle Support (MOS) portal has existed in different forms for a while, although hasn’t necessarily been easy to find without going through specific segments of the extensive MOS training. Recently, the instructions were consolidated into the following highly recommended knowledge base article: KM Note 1298390.1 - How to Monitor a Bug from My Oracle Support The note covers various capabilities, including: How to add the new ‘Bug Tracker’ widget to your MOS dashboard How to add and manage bugs within the Bug Tracker and probably most interesting to MOS users... How to enable email notifications for bug status updates Make sure to pass this KM Note along to your MOS users in case they haven’t already configured this valuable feature.

• No splash screen on hibernate

  - by Marky

  Hibernate is working fine. A bit slow when resuming from a hibernate but I can bear with it just so that I have all open applications on the desktop as I left it. Then again the "slowness" might be because of the 4GB RAM, although I'm assuming only what is used gets swapped and not the entire memory. Going back, my question is has anyone been able to make Ubuntu show a splash screen or some kind of indicator/progress bar to show while hibernating or while resuming? I remember with SuSE on my HP Compaq Presario notebook it had messages appear during and after. Better than nothing, I guess. Thanks in advance! :D

• vlc issue with unity

  - by bob

  I'm using ubuntu 12.04 with unity 3d. I am having troubles to lock vlc (version: VLC media player 2.0.1 Twoflower (revision 2.0.1-0-gf432547)) to the left panel. It doesn't behave the same way other applications do. This is a fresh install from the repo, I didn't change any settings. Ubuntu 12.04 is also a fresh install. For example, (left) clicking on it doesn't bring it to front, but creates a new instance (this in particular is very annoying, if it gets behind another window, that happens to be maximized, there is no way to bring it back up). It also doesn't have a right arrow to say the number of instances there is. Any way around that ?

• Why was Apple&rsquo;s prediction on iPads so wrong?

  - by BizTalk Visionary

  by Robert Scoble on April 14, 2010 Apple has announced it is selling far more iPads than it expected and is delaying the worldwide launch by a month. I am seeing this problem in US too. There are lines in stores (when I went back to buy a third iPad I had to wait in line). The demand is nuts for iPads. So why did Everything Apple guess its prediction so wrong? …….. Read more....

• Openjdk-7-jdk some commands not recognized?

  - by function

  I installed openjdk-7-jdk using apt-get install. However, when I type 'javac', the terminal says, 'bash: /usr/bin/javac: No such file or directory'. I think the link is broken, but how can I fix it? Note: I installed openjdk-7-jdk before, but then I removed openjdk and installed sun-java. Now I deleted sun-jdk and want to go back to openjdk, but javac is not recognized. I'm using Ubuntu 11.10. Edit: Recognized: java; Not Recognized: javac, javadoc, appletviewer, ...

• Disabled WiFi but it keeps re-enabling itself; want it to stay disabled

  - by Mike Uresti

  I have an Alienware X51 desktop with a wireless card, I have it connected via ethernet and want to permanently disable WiFi from ever using itself. When running Windows, I go to device manager and rightclick-disable the Wireless card and that takes care of my problem. Is there a similar method using Ubuntu 14.04? For now, I click on the network icon in the system tray and uncheck 'Enable wifi' but it seems to turn itself back on as I use my computer, I think I have the incident isolated to something with Steam. It seems like after I start the Steam client it always is re-enabled. Hopeful answer: Just disable/remove/block wireless card from ever working.

• Reinstall Ubuntu on Custom Partitions

  - by Forerunner117

  I am attempting to reinstall ubuntu 13.04 without losing my installed software and /home docs. I have read countless threads on this same topic, but nothing seems to apply to my situation. When I originally installed, I had created a separate partition for /home, but I am now unsure of which partition that was. Based on the picture below, where should I be installing the new copy? Also, will I run into problems since I am now running 13.10 and want to put 13.04 back on it? Should I grab 12.04 or 13.10 for this reinstall? Picture: http://i.stack.imgur.com/FL2SY.png (Note: I am performing this reinstall due to a complete muck up of my unity/compiz settings and configuration, resulting in no desktop. I've done my best to resolve this problem first before resorting to this.)

• DesktopCouch does not sync

  - by burli

  I have here two computers, both installed with Ubuntu 10.10. The Laptop uses the Netbook Edition. Both are connected, file sync and Tomboy Notes are working. My Desktop syncs databases with Ubuntu One, my Laptop does not. If I delete for example the contacts Database on my Desktop, the database is back a view seconds later. If I delete the same database on my laptop, nothing happens. (I'm using Futon) If I kill beam, delete the config and try to restart with the dbus-send I got an error Error org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken. How can I fix that?

• How to determine the right amount of up front design?

  - by Gian

  Software developers occasionally are called upon to write fairly complex bits of software under tight deadlines. Often, it seems like the quickest thing to do is to simply start coding, and solve the problems as they arise. However, this approach can come back to bite you—often costing time or money in the long run! How do we determine the right amount of up front design work? If your work environment actively discourages you from thinking about things up front, how do you handle that? How can we manage risk if we eschew up-front thinking (by choice or under duress) and figure out the problems as they arise? Does the amount of up front design depend entirely on the size or complexity of the task, or is it based on something else?

• PASS Summit '12, Day One

  - by AaronBertrand

  I had an incredibly interesting experience getting to Seattle this week. I flew out of Providence through Philadelphia. Apparently there was some smoke in one of the towers at PHL, so our flight was an hour delayed. I missed my connection by three minutes . I was absolutely amazed that after a one-hour, full ground stop, flights shortly afterward were leaving exactly on time. It was like anti-Aaron magic. I got to the gate and watched my plane back away. My luggage never would have made it but it...(read more)

• x11 Remote Desktop with Ubuntu 12.04

  - by BSchlinker

  When I was running Debian, I was able to start a remote session over x11 by just typing gnome-session However, with Ubuntu 12.04, this only seems to result in my desktop and background being forwarded over x11 -- the top bar (where the clock is) and dock are both missing. I tried starting all of unity by executing unity, but that just resulted in a segfault. How can I start a Unity 2D session over x11? Edit: I prefer x11 as I need to tunnel the connection over 2 other servers. I would need to do a good amount of port forwarding within SSH to get any other connections back. Of course, if someone has any other suggestions, I'm willing to listen.

• How do I revert Alt-tab behavior to switch between windows on the current workspace?

  - by chris.ritsen

  Enabling Bias alt-tab sorting to prefer windows on the current viewport as described here made no difference. How can I get back the exact same behavior as 11.04, so that alt-tab only switches between windows on the current workspace? Simply disabling the alt-tab and shift-alt-tab keybindings on the unity switcher seems to have helped, but it still switches workspaces on me sometimes. For example, if I give a terminal window focus then press alt-tab, it switches to another terminal window on any workspace before trying to switch on the same workspace. Also, the Unity switcher still shows up when I alt-tab then hold alt even though I removed its alt-tab keybinding.

• Apress Books - 4 - Introducing Visual C# 2010 - Further comments

  - by TATWORTH

  Apress Books Introducing Visual C# 2010 - ISBN 978-1-4302-3171-4 Having read through parts 1 and 2 of this 4 -part book, I am very impressed by its practical approach to C#. I cannot improve on the by-line "Get started on your C# journey with an expert by your side leading by example" Adam Freeman teaches C# by precept and example. I suspect he drives a Volvo C30 as it comes up in many of the code examples!  Throughout the book there are numerous links back and forth so as to avoid overcomplicating the current topic. I have have no hesitation in recommending this book both to programmers starting out with C# and to the seasoned professional. It is a book that should be on every C# development team's book shelf. There are a few typographical errors in the book, one of which has already made it to the errata, however these are very minor and do not detract from the usefulness of this book.

• Visual Studio 2010 JavaScript Intellisense Behavior

  After I installed Visual Studio 2010 I was having a difficult time editing .js files in Visual Studio. I habitually type the "(" character as soon as the function I want to call is highlighted in the Intellisense window, but in 2010 this behavior was no longer auto-completing the function name. At first I thought this behavior was due to the new "suggestion mode" in Intellisense, but no amount of toggling with CTRL+ALT+SPACE would bring back the auto-complete behavior. It turns out the two...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight.

• Update installed on netbook.. now sidebar icons have disappeared! :oS

  - by Lolly Collier

  hope someone can help. I am not extremely computer literate and my brother installed Ubuntu on my Acer net book when my windows crashed irretrievably . I recently (day before yesterday) had a box come up saying an update (i think it was 10 or 11 .something) i followed the instructions to download and install it and now, all my side bar icons have disappeared. I happened upon an Internet connection by chance and have no idea whatsoever how to get them back. This is quite probably a really stupid question and a really easy fix but as i said earlier, i am pretty much a novice, very far from a computer expert! Thanx in advance :o)

• WF4 &ndash; It has suddenly got interesting

  - by MarkPearl

  I was at Teched two years ago when one of the Microsoft leads said there were three new area’s that we needed to pay attention to for development, namely: WPF WCF WF At the time I was just getting back into development work and had a look at WPF and immediately was sold on the approach. While I haven’t been to involved with WCF directly, I know that some of the guys in my dev team have been and that it too was a success. So what happened to WF? It seemed clunky, and all the demo’s that I saw of it left me scratching my head wondering how if it was going to be useful. Fast forward two years later and while I have had a brief look at WF4, I can immediately see areas where we can use the technology. Does that mean that I think WF4 is the bees knees? I don’t know enough about it yet to really have a solid opinion, but I do think that it is finally going in the right direction. A good introduction to WF4 can be found here.

• Is it possible to power down my external via the eject button?

  - by beanaroo

  I'm trying to convert from Windows 7 to Ubuntu 12.10 with Gnome 3.6. Using the notification area's eject icon, I notice the partition is unmounted but the drive is still powered and spinning... I understand the latter can be taken care of by means of udisks --detach /dev/sdb I really don't want to have to run a command everytime I eject. Windows does the whole process when ejecting a medium via the systray. Is there a way I could add in the command to the eject button? Is there an appropriate place I could file a feature request? Little things like this are making it hard for me to swap back over to Linux. Thanks for the support!
