• Three Hidden Extensibility Gems in ASP.NET 4

  ASP.NET 4 introduces a few new extensibility APIs that live the hermit lifestyle away from the public eye. Theyre not exactly hidden - they are well documented on MSDN - but they arent well publicized. Its about time we shine a spotlight on them. PreApplicationStartMethodAttribute This new attribute allows you to have code run way early in the ASP.NET pipeline as an application starts up. I mean way early, even before Application_Start. This happens to also be before code in your App_code folder...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. Take a look: here.

• Tutorial (or livedisk) for multiseat setup with dual-head display supporting openGL direct rendering?

  - by Tobias Kienzler

  I'm currently running Ubuntu 10.10 (64 bit), the GPU is an ATI Radeon HD 4290 onboard a ASUS M4A89GTD PRO/USB3 mainboard. The Ubuntu wiki doesn't cover 10.10 yet and I also don't know if that method would support direct rendering. I heard mentions of xephyr and xgl, what are the differences? Where should I start? I tried the mdm livedisk but that doesn't boot. I'm also willing to try a different distribution if necessary. Edit: 1 Will the HowTo: A well performing, full eye-candy, accelerated pseudo-multiseat setup on a single dualhead GPU. for Ubuntu 9.04 still work? I'm afraid it omits how to setup two input devices and sound however... Edit: 2 http://multiseatonlinux.blogspot.com/2010/06/part-1-setting-up-base.html covers 10.10 but requires pinning gdm. Is that circumvenatable? Also how does that setup have to be modified for dual-head?

• Homebrewed Headphone Amp Shows Off DIY Resin Casting Process

  - by Jason Fitzpatrick

  Although the guts of this DIY build are worth checking out in their own right, what really caught our eye was the beautiful resin cast case surrounding the build as it’s something that could be adapted to a wide variety of projects. Over at the electronics blog Runaway Brainz they were looking for a slick way to encase an amp project. Rather than go with a project box or similar construction, they did a resin pour and then sanded and polished the resulting encasement. The results are stunning and turn the electronic guts of the amp into a work of art.

• Can I remove "Free space" text from the Nautilus status bar?

  - by DisgruntledGoat

  I want to remove the part in Nautilus that shows free disk space. In theory it may useful but it's so badly designed, every time I select some files my eye gets drawn to "15 GB" instead of the actual size of the files. And with no files selected, it says something like "24 items, Free space 15GB" which at a quick glance looks like the total size of the files. I've looked through the preferences and don't see anything. I'm using Ubuntu 10.10 with Nautilus 2.32.0.

• Solid principles vs YAGNI

  - by KeesDijk

  When do the SOLID principles become YAGNI? As programmers we make trade-offs all the time, between complexity, maintainability, time to build and so forth. Amongst others, two of the smartest guidelines for making choices are in my mind the SOLID principles and YAGNI. If you don't need it; don't build it, and keep it clean. Now for example, when I watch the dimecast series on SOLID, I see it starts out as a fairly simple program, and ends up as a pretty complex one (end yes complexity is also in the eye of the beholder), but it still makes me wonder: when do SOLID principles turn into something you don't need? All solid principles are ways of working that enable use to make changes at a later stage. But what if the problem to solve is a pretty simple one and it's a throwaway application, then what? Or are the SOLID principles something that always apply? As asked in the comments: Solid Principles YAGNI

• How can I make the draggable window border thicker, without changing the appearance?

  - by Bruce Connor

  When you want to resize a window in gnome (as well as in other systems) you can click-and-hold at the window's border and than drag it. The problem is (and do correct me if I'm wrong here) that the draggable border is just a couple of pixels thick in gnome. That tends to be a little frustrating, and contributes to my wrist pains from using the mouse, as it requires very careful movement of the mouse. How can I change the thickness of the area I can click in order to resize a window? I don't want to increase the appearance of the window border, I'm not talking about eye candy here. I want to fine tune this functionality where I can resize a window by dragging its border. Is there a setting somewhere that will change this?

• Custom Silent HTPC Uses Entire Case as a Heatsink

  - by Jason Fitzpatrick

  This silent media center PC dissipates heat in a rather clever way; the entire back of the case is one giant heatsink. Courtesy of computer enthusiast and tinker DeFex, the build isn’t just silent but quite eye catching too. He used a combination of one massive heatsink, custom brackets, acrylic, and bicycle spokes to create a sleek case that looks as much like a computer-inspired work of art as it does a media center computer. Hit up the link below to check out the build gallery and see how he mated the CPU to the heatsink-body with a custom milled aluminum bridge.

• Unity Frustum Culling Issue

  - by N0xus

  I'm creating a game that utilizes off center projection. I've got my game set up in a CAVE being rendered in a cluster, over 8 PC's with 4 of these PC's being used for each eye (this creates a stereoscopic effect). To help with alignment in the CAVE I've implemented an off center projection class. This class simply tells the camera what its top left, bottom left & bottom right corners are. From here, it creates a new projection matrix showing the the player the left and right of their world. However, inside Unity's editor, the camera is still facing forwards and, as a result the culling inside Unity isn't rendering half of the image that appears on the left and right screens. Does anyone know of a way to to either turn off the culling in Unity, or find a way to fix the projection matrix issue?

• On Adopting the Mindset of an Enterprise DBA

  Although many of the important tasks a DBA has to perform should be done 'by hand', keying in commands or using SSMS, the canny DBA with a heavy workload will always have an eye to automating routine tasks wherever possible, or using a tool. 24% of devs don’t use database source control – make sure you aren’t one of themVersion control is standard for application code, but databases haven’t caught up. So what steps can you take to put your SQL databases under version control? Why should you start doing it? Read more to find out…

• Broken BURG install after backup/restore

  - by WindowsEscapist

  Long story short: BURG is stuck in text mode and I can't seem to get it back to the eye-candy. I have purged and then re-installed to no avail. I am running 12.04. The long story: I originally installed onto 12.04 using Super-boot-manager (BURG-manager) and then stopped using it in favour of GRUB because I had too many entries. I then had to backup and restore Ubuntu (partition was deleted and re-created) due to unrelated issues. I re-installed GRUB2 and booted into Ubuntu to re-install BURG, but after re-booting it appears to be stuck in text mode (looks exactly like GRUB 1). Any ideas? I know I'm not supposed to be using it on 12.04 (I think) but it worked before, so what's up?

• What is wrong with Unix/linux

  - by John Smith

  This is a genuine question motivated by Ideal Operating System When I moved from DOS to Linux in the late 90s it was an eye opener for me. Long file names, arbitrarily many extensions etc... Now I look at Linux and Unix and see all sorts of issues. Here are things I see which could be fixed. Too much depends on root, and rootly powers cannot be voluntarily delegated over several users. (I would love to give up my power to manager printers and delegate the job to another account) File permissions are very limited, and there is not much metadata to go with files. The "everything is a file" metaphor is not true, Plan 9 gets it right(er).

• Suggestions on Calculating Advertising Rates [closed]

  - by Jonathan Wood

  Possible Duplicate: How do I set a price for advertising on my website? I recently launched a new developer website, Black Belt Coder. The site is only seeing about 150 visitors per day but, given that it's only been live two months, I feel I'm off to a good start. I'd like to start monetizing the site as soon as possible but consider AdSense and other programs largely a waste of time. I'd like to deal directly with the advertisers but have no idea what to charge. Are there any guidelines for determining advertising rates based on visitors or page views? I don't expect to do PPC. I want to charge a the time period for banner ads, knowing that advertisers will be keeping an eye on the number of clicks.

• image viewer: png vs gif

  - by David Oneill

  I have a bunch of files that have .png extension. However, some of them are actually gif files. Any of the files, I can open them w/ gimp or view them in firefox, but when I try to open them with the Eye of Gnome viewer, it gives an error "Could not load image: Fatal error reading PNG image file: Not a PNG file" Is there: Another image viewer that can open files with incorrect extensions that I could use as default? It would need to have the ability to zoom in and out on images, and scroll through all the images in a folder via arrow keys. An automated way to rename the files that are actually gif files to the correct extensions? Choice 2 is preferred, but I don't now how to tell what type they are. I would be able to put together a bash script to do the renaming if there is a command that could tell me what type they are.

• Dell XPS 15 with Ubuntu 12.10 and HDMI working on hybrid graphics

  - by karolsojko

  So there is a lot of buzz about hybrid graphics being shitty and having a weak support. I'm currently considering buying a new laptop. Dell XPS 15 caught my eye. I will use it for work as well so I will need a large monitor for it connected by HDMI. The question is: has someone got a Dell XPS 15 and can confirm that hybrid graphics support is working fine on 12.10 with no issues on the HDMI. I ask this because all the buzz about the subject stops on 12.04 - does this mean that it's all ok now :) ?
