• PyQt design issues

  - by Falmarri

  I've been working on a my first real project using PyQt lately. I've done just a little bit of work in Qt for C++ but nothing more than just messing around. I've found that the Qt python bindings are essentially just a straight port of C++ classes into python, which makes sense. The issue is that this creates a lot of messy, unpythonic code. For example if you look at QAbstractItemModel, there's a lot of hoops you have to go through that forces you to hide the actual python. I was just wondering if there's any intention of writing a python implementation of Qt that isn't necessarily just a wrapper? Either by Nokia or anyone else? I really like Qt but I would love to be able to write more pythonic code. I hope this is OK to ask here. I'm not trying to start a GUI war or anything.

• Kernel panic when booting from USB

  - by maaartinus

  I downloaded ubuntu-11.04-desktop-amd64.iso and used Universal-USB-Installer-1.8.6.3.exe to format my USB stick und put the ISO on it. When I tried to install from it, I've got a kernel panic just like here, except for the version number (mine was 2.6.38-8-generic #42-ubuntu). My ISO image seems to work, as I installed it into a VMWare player without problems. Booting Linux from USB works surely too, as I did it some time ago with an older Ubuntu version. I can imagine things to try out, e.g., write the image again, try another version, pray, look for patches, etc. However, I'm looking for a time-efficient solution, something what most probably works. An advice of the sort "wait two weeks until it's surely fixed, then download again" is acceptable, I'm determined to switch to Linux, but it can wait a bit.

• Quick path jumping

  - by Sebastian P.

  I was just at a lecture, where I noticed the lecturer using a command (probably aliased) to jump to a specific folder. Example: ~/code$ j sciproj ~/projects/sciproj2011/$ This looked quite slick, so I started wondering: Is this a standard utility, and if so, what is the name? I have two theories as to how it works: It can both create, delete and jump to aliases directly from the command-line in the style of the example, without having to set up aliases in a configuration file or script or whatnot manually. It searches the home directory for a folder matching the name and jumps to it. The second option seems a bit slow, however, so the first would be preferred.

• Programatically loading user controls

  - by PhilSando

  Today's little problem is that I am trying to load user controls from my codebehind like so: Dim myControl As UserControl = Page.LoadControl("~\Modules\Content.ascx")              Controls.Add(myControl)  On running the page myControl is no where to be seen. I wonder why that is? Well after a bit of thought the following come to mind... Am I using the correct code to insert the usercontrol? Is there an alternative available? Does the fact that the usercontrol has a page_load method make a difference? Does the fact that the usercontrol is being called from the page_init method make a difference? Do I need to register the control in my aspx page at design time? I'll be looking to answer these questions as the day goes on!

• Which language to learn C# or Salesforce.com/apex for C++ programmer [closed]

  - by polapts

  Being a C++ programmer with 7-8 years of experience, I wanted to know the market trends. When I searched a little bit I found more jobs with keyword C# than C++ or Java. I am just wondering if it is a good idea to learn C# or Java from a career perspective. Also, I read somewhere about Salesforce/apex. It was mentioned that this is something in vogue. So my question is which technology I should go for C#/Java/Salesforce(Apex) from career perspective? Thanks

• Guide to installing a fully encrypted file system?

  - by Michael Stum

  I have a little Netbook on which I want to install Ubuntu 10.10 (32-Bit) on. However, since it is a portable PC I want to completely encrypt the file system (in case of theft). Currently it runs Windows 7 Starter and I use TrueCrypt which installs a custom boot loader that asks for the password. I remember from the past that Linux can do that as well by putting /boot on it's own, unencrypted partition. Since it's been ages since I last worked with file system encryption (I remember setting up LVM and a custom patched grub to ask for the password) I wonder how that would work nowadays and if there is a step-by-step how-to for it?

• Restoring Grub after Kubuntu installation

  - by justquestions

  I installed Kubuntu on top of my existing Ubuntu 12.04 (64 bit) installation. During Kubuntu installation, I chose lightdm as my default display manager (instead of kdm). Now after rebooting, the Grub has a new color (gray instead of default purplish) and the screen while booting is gray (instead of purplish). I am curious if it is possible to change this grub behavior without removing Kubuntu. I did find a lot of discussion about modifying grub themes but they were not very useful because I do not know what is the default unity grub theme. I did reinstall grub but it didn't change anything. I tried the Grub Customizer but couldn't succeed. Thanks in advance!

• function names - "standartised" prefixes

  - by dnsmkl

  Imagine you have such routines /*just do X. Fail if any precondition is not met*/ doX() /*take care of preconditions and then do X*/ takeCareOfPreconditionsCheckIfNeededAtAllAndThenDoX() A little bit more concrete example: /*create directory. Most probably fail with error if any precondition is not met (folder already exists, parent does not exists)*/ createDirectory(path_name) /*take care of preconditions (creates full path till folder if needed, checks if not exists yet) and then creates the directory*/ CheckIfNotExistsYet_CreateDirectory_andFullPathIfNeeded(path_name) How do you name such routines, so it would be clear what does what? I have come to some my own "convetion" like: naiveCreateDirectory, ForceDirectoryExists, ... But I imagine this is very standard situation. Maybe there already exists some norms/convetions for this?

• SharePoint Apps &ndash; the dark side

  - by Sahil Malik

  SharePoint 2010 Training: more information First of all, I am a proponent of SharePoint apps. As I have said many times over, SharePoint Apps make me very ‘appy, they are very app-propriate. But there are some points to consider that make a bit app-rehensive. These are all mentioned in my book “SharePoint 2013 - Planet of the Apps”, .. but here are some thoughts of the negatives of Apps that I think we need to consider before diving in, Mutliple Servers, More Complexity Apps, by definition will include an extra server. This excludes SharePoint-hosted apps of course. Extra servers by definition will add more complexity. As it is, when you introduce SharePoint to an organization, the number of servers multiply like bunnies. Now you will have additional servers, and these servers talking with each other. You will have to maintain trusts, and you will have to patch more stuff, reset more “admin” passwords – you get my point. Read full article ....

• Why is my content database so large?

  - by PeterBrunone

  If your SharePoint site collection hasn't grown, but your content database has, the most likely culprit is versioning.  If a list -- or worse, a library -- has versioning enabled, the default is to keep every single one.  That means that every time someone edits and checks in a document, its storage footprint increases by the size of the document (and probably a little more).The solution?  It could be a bit painful, but you'll need to go back into each library and restrict the number of versions to keep (three is sufficient for most uses, but your needs may vary).  I suggest keeping only major versions as well, since minor versions are really just stopping points on the way to a published document.Of course if you have a real business need to keep all those versions around, then you'll want to look into an archiving solution that will take the old versions out of the content database but still make them available if necessary.

• Login screen won't accept my password

  - by Raven H

  I recently upgraded to 12.04 from 11.10 and since upgrading have been unable to login to my user profile. The upgrade went okay and I can login to a guest session fine but whenever I try to login to my profile, after entering my password, I just return to the login screen. I've changed my password in Root (passwd 'username')and can log in to tty1 with no issues, it's just in GUI I'm having problems. I'm using a HP dv7 laptop, 32 bit Ubuntu install, Intel® Core™2 Duo CPU P7350 @ 2.00GHz × 2, Nvidia graphics. Any help would be appreciated.

• Long running calculation on background thread

  - by SundayMonday

  In my Cocos2D game for iOS I have a relatively long running calculation that happens at a fairly regular interval (every 1-2 seconds). I'd like to run the calculation on a background thread so the main thread can keep the animation smooth. The calculation is done on a grid. Average grid size is about 100x100 where each cell stores an integer. Should I copy this grid when I pass it to the background thread? Or can I pass a reference and just make sure I don't write to the grid from the main thread before the background thread is done? Copying seems a bit wasteful but passing a reference seems risky. So I thought I'd ask.

• Drawing flaming letters in 3d on OpenGL ES 2.0

  - by Chiquis

  I am a bit confused about how to achieve this. What i want is to "draw with flames". I have achieved this with textures successfully, but now my concern is about doing this with particles to achieve the flaming effect. Am I supposed to have a Path in where i should add many particle emitters along the path that will "be emitting flames"? I understand the concept for 2d, but for 3d are the particles (that are quads) always supposed to be facing the user? Edit: Something else im worried about is the performance hit that will occur by having that many particle emitters, because there can be many letters and drawings at the same time. And each of these elements will have many particle emitters.

• Are there references discussing the use parallel programming as a development methodology? [closed]

  - by ahsteele

  I work on a team which employs many of the extreme programming practices. We've gone to great lengths to utilize paired programming as much as possible. Unfortunately the practice sometimes breaks down and becomes ineffective. In looking for ways to tweak our process I came across two articles describing parallel pair programming: Parallel Pair Programming Death of paired programming. Its 2008 move on to parallel pairing While these are good resources I wanted to read a bit more on the topic. As you can imagine Googling for variations on parallel pair programming nets mostly results which relate to parallel programming. What I'm after is additional discussion on the topic of parallel pair programming. Do additional references exist that my Google-fu is unable to discern? Has anyone used the practice and care to share here (thus creating a reference)?

• How are Programming Languages Designed?

  - by RectangleTangle

  After doing a bit of programming, I've become quite curious on language design itself. I'm still a novice (I've been doing it for about a year), so the majority of my code pertains to only two fields (GUI design in Python and basic algorithms in C/C++). I have become intrigued with how the actual languages themselves are written. I mean this in both senses. Such as how it was literally written (ie, what language the language was written in). As well as various features like white spacing (Python) or object orientation (C++ and Python). Where would one start learning how to write a language? What are some of the fundamentals of language design, things that would make it a "complete" language?

• Unbuntu stuck at boot after update

  - by RandomUbuntuUser

  Well, I installed Ubuntu 11.10 via Wubi on my MSI U270. Everything was running fine, I even got fglrx working after I manually downloaded a .run and executed it. Then I thought of running the complete updates that were on the update manager. I did run it, it took a whole night to complete, I waited a bit as the part came where I had to click on "Restart now". I clicked it, after that I'm stuck at the purple screen with all dots lighted orange. I've been waiting for it to start up for more than half an hour, and there used to be occasional HDD blinks which isn't happening now. Should I reboot? Edit: After the restart not while restarting, forgot to mention that and by the way, is there a way to see anything that's happening just so I know that it ain't stuck?

• Letting go of a project

  - by SkyOrg

  I've been the sole developer of a niche product for my company for nearly 6 years. I've grown quite attached to the project and I enjoy working on it. However, it was the decision of management to take the project out of my hands and move it under the wings of another team. Unfortunately, I'm having a hard time letting go of the project. I'm sad to see it leave my hands since I've put so much time into it and enjoyed working on it, but it also allows me to work on new things. I've even caught myself being a bit hostile to the other team, which is poor on my part. How can I convince myself to just let it go?

• package update in ubuntu on vitual box

  - by Ayusman

  while following one of the tutorials I needed to install a curl package. Here are my system configuration: Virtualbox 4.1 on Windows 7 64 bit. I have installed ubuntu 12.04 on the virtual box. When I try the following: sudo apt-get install curl I see the following errors: [sudo] password for userMe: Reading package lists... Done Building dependency tree Reading state information... Done Package curl is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'curl' has no installation candidate userMe@userMe-ubuntu:~$ When I try the same on a direct installation of ubuntu on a laptop (not a virtual machine) there is no problem. I am assuming this may be because of network settings. Please note that my work PC is in a corporate network and uses auto proxy settings (using a .pac file) for internet access etc. Any help will be appreciated.

• Deforming surfaces

  - by Constantin

  I try to accomplish an deforming physic behaviour for levelsurfaces, but don't get an idea how to start with the implemenation so far. Regardless of the shape from the surface (planes, cubes, spheres…), I want to have small indentations at the positions from game-entitys (players, enemys, objects…). It's kind of complicated to explain, so I illustrated what I'm talking about (here is an example with an sphere): So, the surfaces should be able to deforming themselfs a little bit (to apear like an really soft bed or sofa). My surfaces need probably an high vertices count to get an smooth deforming, but my big problem is the math for calculating this deforming… I'm programming in C/C++ with OpenGL, but will be fine with any advices in the right direction. Any help would be highly appreciated,

• Do wordpress websites get indexed quicker by SE than a regular website?

  - by guisasso

  I registered a couple of domains with the names of categories of products we sell. I then installed wordpress in one of those domains and played around with it for a bit, and left it alone for about a month. There was a link on my regular website to that secondary website and that website was also registered in google's webmaster tools, but that's that. I then searched on google last week for that product category, and to my surprise, that secondary website showed up in the 2nd or 3rd page on google. Now my question is: Do search engines index wordpress websites quicker? I had given up on using wordpress for that website, since it's so simple, but should i use it, would it give me better results? Thanks in advance for the help, if the question is not deleted.

• And at what point of modification to the original does source code with no license become owned by me?

  - by nathansizemore

  I've recently come across a publicly viewable project on Github that has no license associated with it. In this repo, there is a file with the logic and most of the code needed to work as a piece of a project I am working on. Not verbatim, but about 60% of it I'd like to use with various modifications. Once my code base is a little bit more stable, I plan to release what I've done under the WTFPL License. I've emailed the repo owner, and so far have not gotten a reply. I know I have the rights to fork the repo, but if I release a stripped down and modified version of the other project's file with mine, under the WTFPL, am I infringing on copyrights? Per Github's Terms of Service, by submitted a project on Github and making it viewable to the public, you are allowing other users to see and fork your project. Doesn't say anything about modifying, distributing, or using the fork. And at what point of modification to the original does it become owned by me?

• Ubuntu 14.04 + nvidia-331-updates makes a blank desktop screen

  - by Achint

  I upgraded my installation from 13.10 to 14.04. The problem is that whenever I install the Nvidia drivers from the GUI, upon reboot or trying to login again it only shows the wallpaper of my desktop and nothing else. The mouse does move around, but nothing works. I am unable to open a terminal or do anything else. If I go into the tty console and purge the drivers, then things seem to work again. I have an Optimus setup, with an onboard Intel and discrete Nvidia GTX770M card. It's a 64-bit architecture. I really need to work with CUDA, and was hopeful after hearing that nvidia-prime was released, but this is a real downer. Any help on this?
