[Ricard Dias] wrote in to tell us about his guide for developing Linux applications on a Mac. He really enjoys the development environment provided by XCode, and it doesn’t take much to make it work as an all-in-one solution for Linux development.
The real trick here is the use of SSH to access a Linux environment. In this example he uses Ubuntu running as a virtual machine, but also mentions that the same thing can be done just as easily with a separate box as long as it is on the same network as the Mac. SSHFS (the SSH Filesystem) lets him mount the development directory on the Linux box locally. This is where the XCode project and files will be stored, but building the program will be done by the Linux machine via a script calling the make comand via SSH. To test out the newly built program, [L] tunnels in using X11 forwarding for ssh, and the application will be shown as a window in OSX, even though it is running on the Ubuntu machine.
We love SSH and use it all the time. It’s amazing how hand it can be.
[Steve] over at Big Mess O’ Wires has never been so happy to see the “Sad Mac” icon.
A little over a month ago, he decided to take on the task of building his own Mac clone using modern technology. Not to be confused with Mac emulation on modern hardware, he is attempting to build a true Mac clone using an FPGA that is functionally identical to the original.
He is calling his creation the “PlusToo”, with the goal of producing a modern version of the Macintosh Plus. The Plus shares a good amount of hardware with its other original Mac brethren, allowing him to replicate any of the other machines such as the Mac 128K, with a few simple configuration changes.
Building this clone is an incredible undertaking, and it’s a lot of fun to watch the construction progress bit by bit. [Steve] has been diligently working for a little over a month now, recently getting the clone to run 68000 code from the Mac ROM, resulting in the Sad Mac image you see above. While the logo has been dreaded among Mac users for years, it signals to [Steve] that things are coming along nicely.
Provided you haven’t been toiling away in a secret lair somewhere (we’re looking at you [Jack]), odds are you may have seen the news that [Steve Jobs] stepped down as CEO of Apple this past Wednesday.
This earth-shattering news even eclipsed that of the East Coast Megaquakeapocalypse. It sent the blogosphere into a tizzy, sparking a whirlwind of news posts and retrospectives on his career. It’s been impossible to ignore the coverage (we’ve tried), and since we see everyone else writing about it, we feel the need to be at least somewhat up on our current events as well.
At the end of the day though, we don’t care how many patents [Steve] owns, how many failed products he has dreamed up over the years, or that he and [Woz] used to wear matching thongs to the beach in the 80s*.
Nope, we just care about the hacks. So here’s a trip down memory lane highlighting the Apple-related hacks we’ve seen so far in 2011, which will forever be known as the year [Steve Jobs] gave up the reigns at Apple (again).
XBMC on iOS Devices
Overhauling an old Apple keyboard
Mac Pro serial terminal
Taking secret photos of Apple Store patrons
Apple ][ USB keyboard conversion
Apple ][ Weather Display Parts 1, 2, 3
If you find a crusty old IT guy and give him half a chance, he’ll probably regale you with stories of how things were done “in the old days” where no one had their own computer and everyone worked on mainframe-connected dumb terminals. [JSTN] yearned for a true to life terminal display that he could attach to his 2010 Mac Pro, and since there’s no chance anybody is bringing one to market any time soon, he pieced one together on his own.
He dug up a digital VT220 terminal, and got to work trying to interface this office relic with his shiny new Mac. He found a few helpful tips from someone who did the same thing with an Apple ][c, though that solution relied on emulating a terminal – something he did not want to do.
He connected the VT220 to his computer using an off the shelf USB to serial adapter, but the software side of things still needed attention. A quick gettytab tweak later, he had his hardware terminal up and running without much trouble.
He says that he is more than happy to help anyone do the same, so let the mad eBay scramble for old terminals begin!

[Phillip Torrone] gave us a heads up about a project he and [Limor Fried] along with [Mike Doell] have just wrapped up. Their aptly-named “iCufflinks” softly pulsate with light the same way in which you see many Mac products do.
The cufflinks are made from machined aluminum and have the ubiquitous “power symbol” milled into the face. Inside the cufflinks, you will find a small circuit board and a battery, which powers the device for up to 24 hours. The team reverse-engineered the soft LED pulse found in Mac products in order to deliver the exact same visualization in their cufflinks.
Ignoring for a minute, the name and the inspiration for the product, we think they are pretty darn cool. There’s nothing like a set of softly glowing cufflinks to spark conversation at any social gathering.
Like anything else you’ll find on Adafruit.com, the cufflinks are completely open source, so you can feel free to tweak and remix the design any way you’d like.

If you’ve been hungry for more power for your microcontroller projects, but reluctant to dump your investment in Arduino shields or the libraries and community knowledge that go with them all, Digilent has you covered. Their new chipKIT boards are built around the Microchip PIC32 MCU…a powerful 32-bit chip that until recently was left out of the cross-platform scene. A majority of code and quite a number of Arduino shields will work “out of the box” with the chipKIT, and the familiar development tools are available for all three major operating systems: Windows, Mac and Linux.
We first mentioned these a couple weeks ago, but the software was unavailable at the time. Seeing the development tools in action was quite unexpected…

Back in 2004, Apple hobbyist/guru [Michael Mahon] built a cluster of Apple IIe main boards dubbed the “AppleCrate” as an experiment in parallel computing. Now that a few years have passed, he is back with a new iteration of the device, aptly named AppleCrate II.
AppleCrate II was built to address some of the design limits of his first cluster project as well as to expand his parallel computing capabilities. His gripes with the first model were primarily structural in nature. The new system is organized in horizontal layers, using metal standoffs between each main board, rather than relying on a shaky wooden superstructure to keep things together. He also found his previous 8-processor configuration a bit limiting, so the AppleCrate II has 17 nodes – 16 slaves and one main board dedicated to running the operation. The cluster even uses his own homebrew networking stack known as NadaNet to enable communications between the boards.
The project is pretty impressive, so be sure to swing by his site if you want to learn more. He has a ton of technical details there, as well as copies of all of the software he used to get the cluster up and running.
