• Case convention- Why the variation between languages?

  - by Jason

  Coming from a Java background, I'm very used to camelCase. When writing C, using the underscore wasn't a big adjustment, since it was only used sparingly when writing simple Unix apps. In the meantime, I stuck with camelCase as my style, as did most of the class. However, now that I'm teaching myself C# in preparation for my upcoming Usability Design class in the fall, the PascalCase convention of the language is really tripping me up and I'm having to rely on intellisense a great deal in order to make sure the correct API method is being used. To be honest, switching to the PascalCase layout hasn't quite sunk in the muscle memory just yet, and that is frustrating from my point of view. Since C# and Java are considered to be brother languages, as both are descended from C++, why the variation in the language conventions? Was it a personal decision by the creators based on their comfort level, or was it just to play mindgames with new introductees to the language?

• LightScythe Creates Huge Light Paintings

  - by Jason Fitzpatrick

  Earlier this year we showed you how an LED POV staff could be used to visualize network data. This build takes it to another level and allows you to imprint entire words and images into photos. Gavin, a hardware hacker from Sydney, built an open-source POV (persistence of vision) staff after the Wi-Fi visualizer inspired him to begin playing with large POV builds. He built his POV staff using LED strips, wireless controllers, and a laptop to send the signals at the proper intervals to the staff. He can write words, create images, and even send Pac-Man racing across the frame. Hit up the link below to read more about his project and grab his schematics and parts lists.

• Does HTML5 have a feature that enables a user to add an icon to the Apps screen when "installing", and if not, when are they planning to add it?

  - by Jason Livesay

  I know that the mobile bookmark bubble might sort of work for iOS, but it isn't going in the same section. And for Android, bookmarking is really not going to cut it for a mobile HTML5 application install since users just don't think to go to their bookmarks and that bookmark process takes two or three steps. To me this issue of getting the application (bookmark) installed pretty much makes the rest of the HTML 5 features aimed at mobile HTML much less useful. I can't realistically expect users to prefer the bookmark install and launch process over regular apps, so I can realistically expect them to ignore my mobile HTML5 application and use a native app. The groups behind mobile HTML 5 features do seem to be pushing for HTML 5 apps adoption with things like Application Cache etc. To me it seems obvious that the bookmark bubble is not going to cut it. Someone please tell me they have addressed this or at least are working on it?

• Mercury and Sound Waves [Video]

  - by Jason Fitzpatrick

  In this video a tone generator is used to shoot specific frequencies through a large drop of mercury which results in a wide array of unique shapes and patterns created by standing waves–but really, you need to see it to appreciate it. The experiment, put together by Nick Moore, combines a glass dish, a drop of mercury, and a old tone generator to demonstrate standing waves in 3D. Check out the video above to see the experiment in full speed or hit up his YouTube channel to see a remix with music (and other cool science experiment videos).

• DIY Halloween Decoration Uses Simple Silohuettes

  - by Jason Fitzpatrick

  While many of the Halloween decorating tricks we’ve shared over the years involve lots of wire, LEDs, and electronic guts, this one is thoroughly analog (and easy to put together). A simple set of silhouettes can cheaply and quickly transform the front of your house. Courtesy of Matt over at GeekDad, the transformation is easy to pull off. He explains: It’s really just about as simple as you could hope for. The materials needed are: black posterboard or black-painted cardboard; colored cellophane or tissue paper; and tape. The only tools needed are: measuring tape; some sort of drawing implement — chalk works really well; and scissors and/or X-Acto knife. And while you need some drawing talent, the scale is big enough and the need for precision little enough that you don’t need that much. For a more thorough rundown of the steps hit up the link below or hit up Google Images to find some monster silhouette inspiration.

• What is the ideal laptop for creative coding applications?

  - by Jason

  Hi, I am a creative coder using C++(cinder and OpenFrameworks) I am looking to upgrade from my MacBook, which slowed down to about 3fps this morning. My project involves particles systems and fluids reacting to audio analysis data and computer vision data in real-time. SD or HD? no biggie. I have asked many people what computer I need. Ideally, I want a MacBook Pro. But is that enough power? I've been told that I need a desktop for what I am doing though I'd rather stay portable I've been told that I should go PC linux to get the most power but I'd rather stay mac I've been told that RAM is more of bottleneck than processor speed I've been told that the Graphics Card is more important than CPU and that code optimizations such as using trees over lists, proper threading, sending tasks to the GPU make a bigger difference than the hardware!!! what's true?! what do I need? Any suggestions are greatly appreciated

• Turn Your Browser Pane into a Game of Katamari Damacy

  - by Jason Fitzpatrick

  If you’re a fan of Katamari Damacy, a quirky and fun Japanese puzzle game made popular on the PlayStation, you’ll love this Javas script hack that turns your browser pane and its contents into a giant HTML-collecting game of Katamari Damacy. Katamari Damacy, for the unfamiliar, is a addictive game based on the premise that a galactic prince is on a mission to rebuild stars, constellations, and moons accidentally destroyed by his father. You roll around and collect objects (making yourself an increasingly larger ball in the process). This script hack puts a ball on your web browser pane (works best in Chrome) that you can roll around collecting elements from the web page. At first you can only grab links but as you grow you can grab increasingly large objects like photo elements off the page. It doesn’t have the sophisticated graphics of the Playstation version, of course, nor the detailed back story, but it’s a clever little hack that is sure to delight fans of Katamari Damacy.

• The Most Ridiculous Computer Cameos of All Time

  - by Jason Fitzpatrick

  For the last half century computers have played all sorts of major and minor roles in movies; check out this collection to see some of the more quirky and out-of-place appearances. Wired magazine rounds up some of the more oddball appearances of computers in film. Like, for example, the scene shown above from Soylent Green: Spoiler alert: Soylent Green is people! But that’s not the only thing we’re gonna spoil. Soylent Green is set in 2022, and at one point, you’ll notice that a government facility is still using a remote calculator that plugs into the CDC 6600, a machine that was state-of-the-art in 1971. Come to think of it, we should scratch this from the list. This is pretty close to completely accurate. Hit up the link below to check out the full gallery, including a really interesting bit about how the U.S. Government’s largest computer project–once decommissioned and sold as surplus–ended up on the sets of dozens of movies and television shows.

• XboxMP Helps You Find Multiplayer Games for the Xbox

  - by Jason Fitzpatrick

  Searching for the perfect versus or cooperative Xbox multiplayer game can be challenging–the game publisher says it plays four but what exactly does that mean? XboxMP catalogs games with detailed breakdowns of what the multiplayer experience actually entails. You can search first generation Xbox games, Xbox 360 games, and Xbox Live Arcade games with a variety of detailed criteria including the number of players it supports for local, system link, and online play (it may be a deal breaker, for example, that the only way to play the game with 4 players is to have two Xboxes or an Xbox live account).

• Password protect an alias virtual directory

  - by Jason

  I have a main domain being hosted through CPanel. I also have a sub-domain that I would like to appear as a path under the main domain instead of as a sub-domain. So I have: http://example.com/ pointing to the main hosted file. http://example.com/mydir pointing to the subdomain files. This is achieved by a httpd.conf include from the main domain section to set an alias: alias /mydir /path/to/subdomain/files/ Now, that works fine so far. The problem is that if a .htaccess file under /path/to/the/subdomain/files/ contains an error, the alias is completely skipped, and /mydir goes instead to the main host files. That is kind of surprising to me - I would expect an error to return an error instead. Now the killer: if I try to password protect /path/to/subdomain/files/, then trying to access http://example.com/mydir will again attempt to deliver from under the main hosted files and not from /path/to/subdomain/files/ I am not seeing any errors reported on the .htaccess file in the apache error log, so I am assuming the .htaccess is valid: AuthUserFile /path/to/valid/readable/.htpasswd AuthName "Secure Access" AuthType Basic Require valid-user This kind of behaviour does not seem right to me. Is there something obvious that could be causing it? Or is this just the way it works? Perhaps using an alias is the wrong way to go?

• What You Said: How You Share Your Photos

  - by Jason Fitzpatrick

  Earlier this week we asked you to share your favorite tips, tricks, and tools for sharing photos with friends and family. Now we’re back to highlight the ways HTG readers share their pics. Image available as wallpaper here. By far the most popular method of photo sharing was to upload the pictures to cloud-based storage. Many readers took advantage of sizable SkyDrive accounts. Dragonbite writes: I used to use PicasaWeb (uploaded from Shotwell) until I got the SkyDrive w/25 GB available. My imported pictures are automatically synchronized with SkyDrive and I then send out a link to whomever I want. I have another (desktop) computer where all of the pictures are stored from mine and my wife’s camera’s imports so if I need to free up some space on SkyDrive or my Windows 7 laptop, I double-check they are in the desktop computer before deleting them from my laptop (and thus from SkyDrive as well).

• Resize images to specific height value in ImageMagick?

  - by Jason

  I've looked around for this, and can't find an easily implemented solution. Currently I'm working on an application that deals with panoramas. As they come out of the batch stitch process, the dimensions average 18000x4000. Using ImageMagick, how can I downscale those images to a specific height value while maintaining aspect ratio? According to the manual, the convert operation takes in both height and width to resize to while maintaining the same aspect ratio. What I'd like is to put in 600 and 1000 in my existing resize script function and have both a regular viewable image as well as a reduced size.

  - by Jason Fitzpatrick

  While building a nuclear weapon is a complex task in and of itself, the most difficult part is refining uranium. In this informative video, Bill Hammack explains. Weapons and power plants require uranium that contains a greater amount of the isotope uranium-235 than found in natural uranium, which is mostly uranium-238. He outlines the key difficulty in separating the two isotope: They have nearly identical properties. He explains the two key methods for separation: Gas diffusion and centrifuges.
