• DIY Homemade Hybrid Rocket Engine [Video]

  - by Jason Fitzpatrick

  Remember the guy with the cool DIY astronaut ice cream build? He’s back with a mini hybrid rocket engine that runs off oxygen and acrylic. I built a small rocket engine for demonstration purposes. The engine is built from a 2″ diameter acrylic rod through which I drilled a 0.5″ hole. The oxygen at 80 psi or less is passed through the hole and then is forced through a convergent-divergent nozzle at the tail end. The nozzle’s throat is about 0.25″ and expands to 0.625″. I lit the engine by inserting a burning cotton swab (with wooden stick) while a small amount of oxygen was flowing. The acrylic catches fire very easily in a pure oxygen environment. The engine can be throttled and shut off completely, which is a major benefit to hybrid engine designs. Solid-fuel rockets cannot be throttled or shut off, which makes them difficult to control.

• Weekend Project: Make Your Own Ferromagnetic Fluid

  - by Jason Fitzpatrick

  Experiments this simple and fun give you no reason to leave all science-based goofing off to the professionals: whip up a beaker of ferromagnetic fluid to capture magnetic waves in motion. The premise is simple: by combing a viscous liquid (in this case vegetable oil) with a magnetic powder (in this case MICR copy toner) and introducing a strong magnetic source (such as neodymium rare earth magnets), you can actually see the magnetic waves in physical space. It’s like the old magnetic filings on the table top trick, but in 3D. Check out the video above to see how you can mix up a batch of your own.

• Vintage Fan Home Movie Captures the Filming of Return of the Jedi

  - by Jason Fitzpatrick

  Back in 1982, Jeff Broz and a group of his friends heard the next Star Wars film was being shot out in the California desert so they did what any fan would do; they trekked out into the desert and crashed the set. In this 7 minute home video we’re treated to views of the set, actors at work, and other behind-the-scenes footage of the production of Return of the Jedi. It’s hard to imagine, given modern security practices and secrecy surrounding movies, that a bunch of kids could just walk onto a set and start filming these days.

• WolframAlpha Can Now Do In-depth Analysis of Your Facebook Account

  - by Jason Fitzpatrick

  If you’re a big fan of WolframAlpha’s ability to crunch the numbers on just about anything–and we certainly are–you’ll likely be just as delighted as we were to watch it massage the data from your Facebook account. Find out your most liked, discussed, and shared posts, see your Facebook habits, and other neat trends. I unleashed it on my account this morning, not sure what to expect from the results. Within the results tabulation WolframAlpha provided me with all sorts of neat data break downs. I now know exactly how many days it is to my next birthday, the composition of my aggregate posting habits (how many posts are status updates, links, or photos), the time of day when I do the most posting (and what the composition of those posts is), and my average post length. I also know my most liked post and my most commented on post. It will even crunch the numbers on your network of friends (60.6% of my friends are married, for example). By far one of the more interesting data analysis it does on the friendship data, however, is organizing all your friends into relationship clusters so you can see who in your Facebook network is friends with other people in your Facebook network. The service from WolframAlpha is free: simply visit the WolframAlpha search portal and type in “Facebook report” to start the process. You’ll be prompted to create a WolframAlpha account if you don’t have one and to authorize the WolframAlpha Facebook app to access your data. Your Facebook data is cached to your WolframAlpha account for one hour in order to crunch the numbers and display the results.

• Distinction between API and frontend-backend

  - by Jason

  I'm trying to write a "standard" business web site. By "standard", I mean this site runs the usual HTML5, CSS and Javascript for the front-end, a back-end (to process stuff), and runs MySQL for the database. It's a basic CRUD site: the front-end just makes pretty whatever the database has in store; the backend writes to the database whatever the user enters and does some processing. Just like most sites out there. In creating my Github repositories to begin coding, I've realized I don't understand the distinction between the front-end back-end, and the API. Another way of phrasing my question is: where does the API come into this picture? I'm going to list some more details and then questions I have - hopefully this gives you guys a better idea of what my actual question is, because I'm so confused that I don't know the specific question to ask. Some more details: I'd like to try the Model-View-Controller pattern. I don't know if this changes the question/answer. The API will be RESTful I'd like my back-end to use my own API instead of allowing the back-end to cheat and call special queries. I think this style is more consistent. My questions: Does the front-end call the back-end which calls the API? Or does the front-end just call the API instead of calling the back-end? Does the back-end just execute an API and the API returns control to the back-end (where the back-end acts as the ultimate controller, delegating tasks)? Long and detailed answers explaining the role of the API alongside the front-end back-end are encouraged. If the answer depends on the model of programming (models other than the Model-View-Controller pattern), please describe these other ways of thinking of the API. Thanks. I'm very confused.

• The Infinite Jukebox Creates Seamless Loops from Your Favorite Songs

  - by Jason Fitzpatrick

  Why limit yourself to simply listening to a song on repeat when The Infinite Jukebox can use algorithms to turn your song into a seamless and never ending tune? Unlike simply looping a song from the start to the end over and over, The Infinite Jukebox analyzes the song and looks for spots where it can seamlessly transition from one point in the song to a previous point to create a sense of never-ending music. Some songs worked better than others in our testing–Superstition by Stevie Wonder, for example, worked flawlessly but Gangnam Style by Psy got stuck in a short loop that sounded unnatural.

• IKEA Lamps Hacked into Flexible Speaker Mounts

  - by Jason Fitzpatrick

  This simple hack combines the swing arms of two IKEA work lamps with a set of computer speakers for flexible and easily adjustable sound. IKEAHackers reader Bill Dwyer wanted an easy way to get the speakers off his desk but still be able to easily adjust them. By hacking apart two IKEA work lamps (he removed the light assembly and snipped the wires off) he was able to attach his computer speakers to the arms and, in the process, get them off the desk. The arms make it super simple to adjust the speakers exactly where he wants them, including towards other parts of his office/apartment.

• Roll a DIY Camera Jib for $25

  - by Jason Fitzpatrick

  Video gear is expensive; save your pennies by building a DIY camera jib for smooth camera movement on a budget. Over at Oliva tech they explain just how few parts you need to build their DIY jib: The guys here at the studio mocked up a simple DIY jib that is not only ridiculously inexpensive to piece together, but also very straight forward. The point of this jib was to get a very wide range of motion from top to bottom with only a few feet of 0.75? square tube, 1? angled aluminum, 1/4? nuts and bolts, and nylon washers is all you’ll need to put the jib together. This light weight jib can be used on small portable tripods, but will require a fluid head for panning left and right. Hit up the link below for a detailed parts list and build guide.

• VMware Player- no Maverick GUI after install

  - by Jason

  I'm experimenting with using both VMware Player and Virtualbox to run an Ubuntu VM in Win7. I have the VB install of Maverick working fine, and with only a few quirks such as slow response in Firefox scrolling and the occasional freeze, it works fine. However, making backup copies of a VB machine for storage is a PIA, and so I would like to see how Player works in the same situation. I created a new VM with 2GB RAM & 30GB hard drive space. The install went smoothly, but everytime I start the VM, no GUI shows and I have no mouse control. It brings me to a screen saying Ubuntu Easy Install: VMware Player is installing VMware Tools.. please wait. At this point, I get a login prompt and then goes to a standard CLI interface. At this point, I have no mouse control at all. The CPU and memory gauge that I have as a Win7 screenlet shows no changes and minimal HDD activity. The VMWare site says to install the Tools by a tarball, going to VMInstall VMware Tools, but I can't do that with no mouse control. Any solutions?

• How do you decide what kind of database to use?

  - by Jason Baker

  I really dislike the name "NoSQL", because it isn't very descriptive. It tells me what the databases aren't where I'm more interested in what the databases are. I really think that this category really encompasses several categories of database. I'm just trying to get a general idea of what job each particular database is the best tool for. A few assumptions I'd like to make (and would ask you to make): Assume that you have the capability to hire any number of brilliant engineers who are equally experienced with every database technology that has ever existed. Assume you have the technical infrastructure to support any given database (including available servers and sysadmins who can support said database). Assume that each database has the best support possible for free. Assume you have 100% buy-in from management. Assume you have an infinite amount of money to throw at the problem. Now, I realize that the above assumptions eliminate a lot of valid considerations that are involved in choosing a database, but my focus is on figuring out what database is best for the job on a purely technical level. So, given the above assumptions, the question is: what jobs are each database (including both SQL and NoSQL) the best tool for and why?

• E3 Booth Babes Display a Painful Lack of Video Game Knowledge [Video]

  - by Jason Fitzpatrick

  If you thought a prerequisite for manning a booth at an electronics expo was a passing knowledge of the electronics and games you were promoting, you were wrong. In the above video Chloe Dykstra puts a set of “booth babes” from the E3 2011 conference to the test by asking them simple questions about video games both new and old. If you’re a gaming fan and you can watch this video without laughing out loud you’ve got an iron will (or you’re shaking your head in disbelief that someone could work a gaming convention and not know the answers to these questions). We won’t lie, we were shaking our head when the one model admitted that she’d worked at GameStop for a year and still didn’t know any of the answers. What questions would you put on list?
