• Notebook MSI GT640 - noisy fan - Ubuntu 11.10 x64

  - by pablo

  I have all time this issue when using Ubuntus, the fan (fans?) runs most off the time and between 60%~100% even in idle which is weird. The GPU temperatures are mostly around 80 degrees and I don't think it's right :( I always use Jupiter with power saving preset and add the line in linux default like this: quiet splash pcie_aspm=force i915.i915_enable_rc6=1 So it helps a little (fan just doesn't run all the time 100%...) What else can I do? The notebook spec is: Core i7-720 (8 threads) NVIDIA GTS250M So it's rather one of the first, not so silent and cold notebooks;), with Core i7 family and without optimus technology (as nvidia GPU is the only graphic card built-in) but anyway I don't have theese strange hot times in Windows 7.

• What programming languages have you taught your children?

  - by Dubmun

  I'm a C# developer by trade but have had exposure to many languages (including Java, C++, and multiple scripting languages) over the course of my education and career. Since I code in the MS world for work I am most familiar with their stack and so I was excited when Small Basic was announced. I immediately started teaching my oldest to program in it but felt that something was missing from the experience. Being able to look up every command with the IDE's intellisense seemed to take something from the experience. Sure, it was easy to grasp but I found myself thinking that a little more challenge might be in order. I'm looking for something better and I would like to hear your experiences with teaching your children to program in whatever language you have chosen to do so in. What did you like and dislike? How fast did they pick it up? Were they challenged? Frustrated? Thank you very much!

• How do I get Flash 10.2 RC + Crystal HD for HW accelerated video to work?

  - by Gee

  I have a netbook with a N450 Atom and a BCM70012 aka Crystal HD card. On Windows 7 I can play HD flash video with very little CPU usage because of the RC of Flash 10.2. I did some reading and saw posts claiming that the Crystal HD card is finally supported by the newer Flash 10.2 RC in Ubuntu but I can't get it to work. I can confirm that flash 10.2 is loaded and used, and there's even a HW acceleration option that is enabled in the settings but performance is horrible. From what I read, the Crystal HD card is supposed to be enabled on 10.10 by default - I don't know if it is. I tried installing drivers for it in various ways but HD flash video is still a slideshow So does anyone have it working? If so, how'd you set it up?

• Is it worth being computer languages polyglot?

  - by Anton Barkowski

  You can often hear that programmers should learn many different languages to improve themselves. I still go to school and don't have big programming experience (a little more than year). But what was noble intention to improve programming skills turned into some kind of OCD: I feel that I won't calm down until I learn all relatively known programming languages. And here is question itself: Will being programming languages polyglot actually help you (And I don't mean usual "Programmer should know at least all paradigms", I mean really all languages you usually hear about)? Does anybody have similar experience? Does it help with job/skills/career? How often are you able to apply those skills?

• Looking for a FormBuilder that gives me all images and sourcecode to my form

  - by Tracy Anne

  Wow, I started my search this morning and didn't think it would be so difficult to find. I'm just tired of spending hours putting together simple html forms in dreamweaver. I'm an enthusiast web developer mostly focused on php and mysql. I hate CSS and HTML and I'm looking for a simple program that will put a form together for me where I can then completely embed the form into my site. I'll do all of the programming to attach it to my database I just need the form and images. I've looked into jotform, wufoo, 123forms etc but it seems like they all want to keep my form on their servers in one way or another. It looked like jotform had a developers version but $450 bucks is a little steep for a part timer like me. Is there no simple software out there that will throw a nice stylized form together for me?

• Alan Turing Needs Your Help

  - by Chris Massey

  Well. sort of. Clearly, you are using a computer. If you are on this site, you are probably quite familiar with computers as artifacts of our modern society. Hopefully, you are also familiar with the fact that Alan Turing, logician and mathematician extraordinaire, was instrumental in laying down the foundations of modern computer science, and did a little work to help turn the tide of WWII in the Allies' favor. Hold that thought. A phenomenal collection of Turing's papers (including his first ever...(read more)

• Architecting multi-model multi-DB ASP.NET MVC solution

  - by A. Murray

  I have an ASP.NET MVC 4 solution that I'm putting together, leveraging IoC and the repository pattern using Entity Framework 5. I have a new requirement to be able to pull data from a second database (from another internal application) which I don't have control over. There is no API available unfortunately for the second application and the general pattern at my place of work is to go direct to the database. I want to maintain a consistent approach to modeling the domain and use entity framework to pull the data out, so thus far I have used Entity Framework's database first approach to generate a domain model and database context over the top of this. However, I've become a little stuck on how to include the second domain model in the application. I have a generic repository which I've now moved out to a common DataAccess project, but short of creating two distinct wrappers for the generic repository (so each can identify with a specific database context), I'm struggling to see how I can elegantly include multiple models?

• Help with creating symbolic link

  - by user1737794

  I'm a little bit confused with how the symbolic links work. I hope someone can guide me in the right direction. I want to put a demo online from our software, which normally only runs locally on a Mac Mini. So I put all the files in the var/www from my Ubuntu 12.04 server installation. There are a lot of hardcoded links in the software which point to "/Applications/XAMPP/xamppfiles/htdocs/narrowcasting" Of course I can change all these code on my html/php files in /var/www, but that would be quite annoying. I hope I can fix this by creating a symbolic link. For example I have a directory called thumb in /var/www/thumb. The php code is trying to put a image in /Applications/XAMPP/xamppfiles/htdocs/narrowcasting/thumb. Can anyone give me a tip how to achieve this with a symbolic link? Thanks in advance.

• How to disable the alt-hotkey behavior on gnome terminal?

  - by farleyknight

  This is not just gnome terminal, but pretty much all gnome windows: When you hold the "alt" key, you can press the first letter of one of the menu items. This will let you scroll that menu without clicking on it directly. This is okay on any other window, like say Firefox, but on gnome terminal, it steals the keys I use for emacs!! There is very little chance of me learning a new set key combinations if I can avoid. If I can't isolate this just to gnome terminal, I'm fine with that.

• Question about Target parameter of Matrix.CreateLookAt

  - by manning18

  I have a newbie question that's causing me a little bit of confusion when experimenting with cameras and reading other peoples implementations - does this parameter represent a point or a vector? In some examples I've seen people treat it like a specific point they are looking at (eg a position in the world), other times I see people caching the orientation of the camera in a rotation matrix and simply using the Matrix.Forward property as the "target", and other times it's a vector that's the result of targetPos - camPos and also I saw a camPos + orientation.Forward I was also just playing around with hard-coded target positions with same direction eg 1 to 10000 with no discernible difference in what I saw in the scene. Is the "Target" parameter actually a position or a direction (irrespective of magnitude)? Are there any subtle differences in behaviors, common mistakes or gotchas that are associated with what values you provide, or HOW you provide this paramter? Are all the methods I mentioned above equivalent? (sorry, I've only recently started and my math is still catching up)

• Asset displays in the UI

  - by Owen Allen

  I've seen a little bit of confusion about how the UI displays assets and asset information, so I thought I'd explain how information and actions are displayed.  In Ops Center, operating systems, servers, zones, Oracle VM Servers, and anything else that you can manage are called assets. When you discover them, Ops Center puts together a model in the navigation pane that shows the relationships between the assets. For example: This tree shows three servers, and the Operating Systems on each one. If one of the operating systems was a global zone, we'd see the non-global zones beneath the global zone as well. However, when you select an asset, the info in the center pane and the actions in the actions pane are the ones that apply to that specific asset, and not to its related assets. If you select a server, for example, you'll see service request info and have the option to provision a new OS. If you select an existing OS, you'll see file system information and have the option to update the OS. Actions that apply directly to the hardware aren't visible from the OS view, and vice versa.

• Getting a sphere to roll down a .FBX object Unity3D/C#

  - by Timothy Williams

  I'm working on a little ramp and ball game in Unity, I modeled the ramp outside Unity and exported it to a .FBX file, then I imported the ramp in to Unity. I set up the ball and ramp, both have Rigidbodies, Ramp is set to isKinematic = true, yet when I play the game the ball just falls right through the ramp and hits the floor below it fine. So it's something wrong with the ramp. Am I doing something wrong? Are .FBX files unable to apply physics? Thanks, Tim.

• Comparing Checksums

  - by Sean Feldman

  This is something trivial, yet got me to think for a little. I had two checksums, one received from a client invoking a service, another one calculated once data sent into service is received. Checksums are plain arrays of bytes. I wanted to have comparison to be expressed as simple as possible. Quick google search brought me to a post that dealt with the same issue. But linq expression was too chatty and I think the solution was a bit muddy. So I looked a bit more into linq options presented in the post, and this is what ended up using: var matching = original_checksum.SequenceEqual(new_checksum); Sometimes things are so simple, we tend to overcomplicate them.

• Beginner's guide to writing comments?

  - by Cameron

  Is there a definitive guide to writing code comments, aimed at budding developers? Ideally, it would cover when comments should (and should not) be used, and what comments should contain. This answer: Do not comment WHAT you are doing, but WHY you are doing it. The WHAT is taken care of by clean, readable and simple code with proper choice of variable names to support it. Comments show a higher level structure to the code that can't be (or is hard to) show by the code itself. comes close, but it's a little concise for inexperienced programmers (an expansion on that with several examples and corner cases would be excellent, I think).

• Web Service - SOAP

  - by seth

  My experience with web services is slim and I'm trying to understand this a little bit more. I have done for instance a web service using visual studio. In order to use it, I add a web service reference in my projects and this creates a proxy and the use is pretty simple. Does this use SOAP? I ask this because i will be now facing a web service that i must communicate using SOAP with attachements and i'm trying to understand the concept behind this and the difference to what i have done so far. Will the proxy still be viable or do i need to create the XML by hand and post it to the web service? This concepts still confuse and so any help is appreciated. EDIT: I'm not developing the service, i will be just using it.

• Do private static methods in C# hurt anything?

  - by fish

  I created a private validation method for a certain validation that happens multiple times in my class (I can't store the validated data for various reasons). Now, ReSharper suggests that the function could be made static. I'm a little reluctant to do so due known problems with static methods. It would be a private static method. My question is, can private static methods cause similar coupling and testing problems like public static methods? Is it a bad practice? I would guess not, but I'm not sure if there is a pitfall here.

• I feel stuck in the center of Python, How to get past beginner

  - by Isov5

  I really apologize if this doesn't follow the S.O rules but I need a little help, I personally still classify myself as a beginner in python, Yet I've wrote a very small and VERY SURE impractical program for my boss to use. I know I'm still a beginner because simple things still perplex me but every book I read for beginners honestly just rehashes what I do already know but every 'more advanced' book doesn't really allow me to learn, they depend on example files and I never really understand why they built 'said' function or 'said' class. So onto my question... Is there any recommendations on a book or ANYTHING that pushes me out of this stage, I've used head first and normally they are really good but my issue there is they have me back tracking just to move forward again, It worked in HTML but its confusing in Python, basically I think I need to build a program while following along, Again I like HeadFirst's style but I need something that isn't going to make me have to remember one thing just to forget it... for record, I've checked into some O'Reilly books
