• How can I set up a keyboard shortcut so that Ctrl+Backspace = Del?

  - by Palantir

  As an old mac user, I am used to hitting Ctrl+Backspace, and the effect is the same as if I pressed Del. I have recently purchased an Asus N53SV laptop which has replaced my MacBook, but unfortunately this laptop has a very annoying keyboard layout, where the Del key is in a non standard position, and moreover it is TINY. Is it possible to get the Ctrl+Backspace combination to issue a Del and how would I do this? Using Kubuntu, but I believe this is to be done at X level, not at desktop, am I right? Thanks!

• eepc 100h ubuntu 12.04 external monitor higher resolution modes force a rotated display

  - by Acky

  Hi I have a eeepc 1000h netbook. I've just installed ubuntu. I mainly use an external display (samsung ta350 full hd 22 inch affair) but when I select 1080 from the dropdown list, my only options are for a rotated portrait. My neck's non too supple, so tilting my head for extended periods is not really viable. :-) Any ideas on making ubuntu display 1080 normal landscape? It must surely be possible. My gparted boot cd does it perfectly. Any help greatly appreciated. Cheers!

• Windows: starting sqlplus in new window from cygwin bash

  - by katsumii

  When I start sqlplus, more often than not, I want it to start in new window,whether it be on Linux/Solaris GNOME or Windows.I seldom use GNOME so I never bothered to figure out how.On Windows, one can use Windows menu or Win+R "Run" dialog but I prefer usingbash. Because, this way, I can keep the history in ~/.bash_history file.There are 2 ways. Using cmd.exe or cygstart.For example, to start default sqlplus.exe to connect to default local instance. $ cmd /c "start sqlplus sys/oracle as sysdba" 2nd example. To start sqlplus in 2nd Oracle home and to connect to non-default local instance. $ ORACLE_SID=orcl cygstart /cygdrive/g/app/product/11.2.0.3/dbhome_1/BIN/sqlplus scott I hope this tip helps reducing your DBA time.

• HP 655 Notebook (Ubuntu 12.04) wireless internet disabled after running updates

  - by Bastian

  Today the update-manaeger suggested that I should download some updates. So I did. After the updates were installed I had to reboot the system. After the reboot my notebook doesn't see any wireless networks. I was looking for a long time on the internet for answers but non of them applies to my case. I have the idea, it has got something to do with the kernel I am currently using (Linux 3.2.0-55). Is this one new for Ubuntu 12.04? When I boot my system I can choose to use an older kernel (linux 3.2.0-32). When I use this one the notebook does see the wireless networks. This is my network card according to the command lspci: Ralink corp. RT3290 Wireless 802.11n 1T/1R PCIe Anyone an idea to fix my problems with wireless internet?

• What is the most complicated data structure you have used in a practical situation?

  - by Fanatic23

  The germ for this question came up from a discussion I was having with couple of fellow developers from the industry. Turns out that in a lot of places project managers are wary about complex data structures, and generally insist on whatever exists out-of-the-box from standard library/packages. The general idea seems to be like use a combination of whats already available unless performance is seriously impeded. This helps keeping the code base simple, which to the non-diplomatic would mean "we have high attrition, and newer ones we hire may not be that good". So no bloom filter or skip-lists or splay trees for you CS junkies. So here's the question (again): Whats the most complicated data structure you did or used in office? Helps get a sense of how good/sophisticated real world software are.

• How Can I Upgrade to 11.10 from the Command Line?

  - by nmagerko

  I am trying to upgrade my 11.04 Ubuntu operating system to 11.10, as the current system is not the most recent. However, I cannot use the GUI to upgrade - as from past experience I have learned this - because my graphics hardware only works on 10.04 to 11.04 (non-inclusive) and from 11.10+. So once I can get to 11.10, I should be just fine. Because of this, I need to find a way to upgrade the OS from the command line. Can this be done? Thanks for any and all help.

• Public versus private inheritance when some of the parent's methods need to be exposed?

  - by Vorac

  Public inheritance means that all fields from the base class retain their declared visibility, while private means that they are forced to 'private' within the derived class's scope. What should be done if some of the parent's members (say, methods) need to be publicly exposed? I can think of two solution. Public inheritance somewhat breaks encapsulation. Furthermore, when you need to find out where is the method foo() defined, one needs to look at a chain of base classes. Private inheritance solves these problems, but introduces burden to write wrappers (more text). Which might be a good thing in the line of verbosity, but makes changes of interfaces incredibly cumbersome. What considerations am I missing? What constraints on the type of project are important? How to choose between the two (I am not even mentioning 'protected')? Note that I am targeting non-virtual methods. There isn't such a discussion for virtual methods (or is there).

• Breaking in to Programming

  - by Kevin

  I've noticed that there is a gap between getting formal education in computer science as a student and entry-level/junior programming jobs. Obviously entry-level programming requires that you know some programming but how much do you need to break in? I'm in a QA non-coding role with basically a minor in CS, looking to improve my own programming skills to eventually switch industries. However I'm completely at a loss as to what I should be focusing on learning and am curious as to the steps other people have taken to get experience post-undergrad.

• XNA: Runtime differences in ClickOnce install versus development version

  - by Sean Colombo

  I have a game written in XNA, and I use ClickOnce installers to distribute the game to testers. I keep once computer as a test machine which does NOT have development environments installed, so that I can test the installed version. We've found a reproducible bug in our game, but the bug ONLY occurs on the non-development machines that use the ClickOnce installer. The bug is related to some of our code for moving around 3D objects and is not tied to Networking or GamerServices. Are there known differences in the ClickOnce runtime and the version on dev? Are there any best-practices for debugging something like this?

• Bouncing ball isssue

  - by user

  I am currently working on the 2D Bouncing ball physics that bounces the ball up and down. The physics behaviour works fine but at the end the velocity keep +3 then 0 non-stop even the ball has stopped bouncing. How should I modify the code to fix this issue? ballPos = D3DXVECTOR2( 50, 100 ); velocity = 0; accelaration = 3.0f; isBallUp = false; void GameClass::Update() { velocity += accelaration; ballPos.y += velocity; if ( ballPos.y >= 590 ) isBallUp = true; else isBallUp = false; if ( isBallUp ) { ballPos.y = 590; velocity *= -1; } // Graphics Rendering m_Graphics.BeginFrame(); ComposeFrame(); m_Graphics.EndFrame(); }

• PPC Affiliate networks for web-applications [on hold]

  - by machete

  I want to run a browser-based social media (Twitter, Instagram,...) account management tool (justunfollow.com) which monetizes through ads. But many affiliate networks like Google AdSense or media.net require your website to have "high quality content". AdSense explicitly states: "Google ads, search boxes or search results may not be: * Integrated into a software application (does not apply to AdMob) of any kind, including toolbars. * Placed on any non-content-based page. (Does not apply to AdSense for search, mobile AdSense for search, or AdMob.)" Are there serious & trustworthy affiliate networks which allow ads to be published on a web application?

• What effect does using itemprop="significantLinks" on anchors have for SEO?

  - by hdavis84

  So as I've described in a previous post about span tags within head tags, I'm practicing application of microdata via http://schema.org. Anyone who's browsed the documentation there knows that there's a lot of need for improvement for more clear understandings on use for each property. My question on this post is more about the "significantLinks" property and how it effects SEO for on page, in content anchored text. Does anyone have any more information regarding whether its good to use for link optimization? I understand what schema.org means that it's to be used on "non-navigational links" and those links should be relevant to the current page's meaning. But will using this property hurt SEO or make SEO better for each page? Thanks in advance, as by answering this with accurate information you are helping not just me, but many people who are trying to make their customers more successful through helping their rank for relevant keywords to their business, bringing them more search engine traffic.

• Skype 4.2 crashes and bugs on 13.10

  - by Juhani Taylor

  I've installed Skype and it appears to work fine right up until the point where I try to call someone. If I try to video call someone then the programme freezes and I have to force quit. I've tried several 'solutions' I've found on various forums but none seem to work. Now, when I try to call the Echo service as a test to see if the bug's fixed, it seems to connect and start the non-video call, except that it's completely silent. No audio at all. Any help? It seems to be 2 separate issues: audio and generic crashing. Anyone come across these and found solutions?

• Is this a bad time to be majoring in computer science?

  - by ATMathew

  There has been a lot of media attention paid in recent months and years to the increase in CS majors and the possibility of a second tech bubble. Some news reports have suggested that as more people enter CS, the market could be flooded with CS professionals and jobs could be increasingly difficult to find. Is this a bad time to be majoring in computer science? Edit: I'm a non-trad student who allready has a Bachelor's degree in economics and will be pursuing a CS degree starting this upcoming summer semester at the Univ of Kansas. I've been programming for about two/three years and just need a more formal education to fill the holes in my head. I have an interest in CS, it's just that I am worries about the prospects for the future.

• Open Source License that prevents re-selling

  - by Vaccano

  I have an open source project that is a add-in to TFS (ie it is for developers and those using TFS.) It is currently using the GPL. But it occurs to me that the GPL does not really represent what I am trying to do with my license. I want my code to be free to everyone who wants to use it. And if you modify it and use it then that is great too. You should not have to open source your modifications. But I would like to block someone from building my code and selling it. Or modifying it and selling it. (Anyone that wants to do that should have to negotiate a separate license with me.) Is there an open source license that prevents re-selling, but allows full non-vending use for a person/company that downloads it?

• RPG Item processing

  - by f00b4r

  I started working on an item system for my (first) game, and I'm having a problem conceptualizing how it should work. Since Items can produce a bunch of potentially non-standard actions (revive a character vs increasing some stat) or have use restrictions (can only revive if a character is dead). For obvious reasons, I don't want to create a new Item class for every item type. What is the best way to handle this? Should I make a handful of item types (field modifiers, status modifiers, )? Is it normal to script item usage? Could (should?) this be combined with the above mentioned solution (have a couple of different sub item types, make special case items usage scripted)? Thanks.

• Microsoft étend son projet 4Afrika à l'Afrique du Sud, pour connecter les zones rurales à Internet

  Microsoft étend son projet 4Afrika à l'Afrique du Sud, pour connecter les zones rurales à Internet Dans le domaine de la télécommunication, une zone blanche correspond à une zone du territoire non couverte par un réseau donné (le plus souvent réseau de téléphonie mobile ou internet). Dans son projet Microsoft 4Afrika, l'entreprise ambitionne d'exploiter ces zones blanches au Kenya. Des parties rurales de la province de Limpopo, au nord-est de l'Afrique du Sud, pourraient se voir connectées à Internet. Le projet pilote qui permettra à cinq écoles primaires et secondaires de surfer sur le web devrait fournir au pays la capacité de fournir à 80 % de sa population l'accès au web d'ici 2020.Paul G...

• Sharing a mounted Truecrypt volume via Samba

  - by user10492

  Been banging my head against the wall on this one for a while. I have an encrypted (via truecrypt) partition on a drive. In windows, I mount it locally and share it on my local network. I'm trying to do the same in Ubuntu 10.10 but am running into permission issues. The tc volume has funny permissions and I just can't seem to figure out a way to access it (unsecurely of course) over my network. Other non-tc volume shares work just fine. To recap, I mount a truecrypt volume in Ubuntu and set up a samba share as normal. The share shows up on my local network but accessing it gives 'permission denied'. Mounting as a network drive using a password does not seem to work either. Any insight would be greatly appreciated.

• Intro to NoSQL with RavenDB

  - by dgreen

  I did a talk on RavenDB back on 9/19/2012. Here was my abstract: "RavenDB is a document database which is gaining popularity in the 'NoSQL' movement. This session will introduce you to some non-relational concepts and describe how they compare/contrast with the relational solutions you're already familiar with. We'll go through the basics of RavenDB and show how easy it is to use from .NET” My next goal is to figure out how to post the slidedeck here (and maybe the code samples if I'm feeling ambitious). Then, the slides can be downloaded for only three easy payments of $39.99. However  for this one time special offer they are currently being given away absolutely FREE with a signup to http://meetup.trinug.org Footnote: I probably shouldn't have to say this, but my last comment about charging for my slidedeck was a joke. I have an odd sense of humor for those who don't already know me :)

• How to install again Update Manager after uninstalling it

  - by biezdar

  Ok, the thing is this I tried asking many times on few ubuntu forums how to deal with my non-responsive Update Manager, but all I was getting was the same stuff (run it from the terminal, run some lines, apt-get update blah blah). Nothing was helping. Eventually I went mad Windows style and tried to simply uninstall it and install it again. The problem is - how to install it again? Can't do it through Software Center, can't really build a package (because I'm too stupid to do that). And I seriously want to avoid reinstalling the whole system. I am running a 12.04 verison (Update Manager was unable to update to a newer one) Please help. I am furious with this thing.

• Why do recruiters contact you instead of the companies themselves? [closed]

  - by Chloe

  When posting my resume, I get hounded by recruiters who try to sell me on a job. Why don't the actual company HR employees contact me directly? My information is available for them to find. Wouldn't they save money by bypassing the recruiter fees? Out of the hundreds of recruiter phone calls, only 2 actual companies contacted me directly (and 2-3 other non-company individuals). Should the HR employees be let go if they are so irrelevant? (The careers exchange doesn't allow posting questions.)
