OSProcess examples

Well, I finally got off my butt and created a package with examples of how to use OSProcess and CommandLine. It only has a couple of examples until I dig up more examples. I think I started using OSProcess back in Pharo 4. I find it easier to use than OSSubprocess because you can just paste commands from the shell into command: and waitForCommand:. The package is on Smalltalkhub.com and the particulars for Monticello are:

Pine A64 Dreams

Well, Raspberry Pi has some competition in the single board computer space, The Pine A64. There currently a Kickstarter project to fund a 64 bit computer with similar or more powerful specs.

The PINE64 CPU is a quad-core ARM A53 64-bit processor that runs at 1.2GHz.

The GPU on the PINE A64 is a dual-core MALI-400 MP2 and runs at 500MHz, capable of 1.1 Gpixel/s throughput. This means the graphics capabilities are slightly higher than the original X-Box’s level of performance.

PINE A64 board is powered by the latest 64-bit quad core ARM A53 CPU and delivers up to 20-30% better performance than other 32 bit open source counterparts.

Here’s a chart comparing some features on the competing systems.

Right now the only OS available is Android, but the company producing Pine A64 saying it’ll have Ubuntu Snappy and Lubuntu available, they just don’t say when. I preordered the $29 Pine A64+ with 2 gB of memory figuring that the additional ram will be useful. Eventually, I want run Pharo on it, but that may take some time.

Hello world!

There’s an interesting web site: called SMALLTALK ZEN about Web Development with Pharo Smalltalk and Seaside. Pharo Smalltalk contains the reference implementation of Seaside, a web framework that makes it easier to develop web applications. There’s an article on Wikipedia about Seaside and then there’s the Seaside web site.
