Nebra Anybeam turns your Raspberry Pi into a pocket home cinema projector

TVs are available to buy in truly huge sizes these days, and with 4K (and upwards) resolution, movies and TV shows really come to life. But there’s something even more magical about watching a film projected onto a screen or a wall. With the right setup, it can be like having a cinema in your home. You don’t necessarily need to spend a fortune on a projector though. Nebra Anybeam can turn your Raspberry Pi into a cinema projector that you can slip into your pocket and take anywhere.

Back in the Day: UNIX, Minix and Linux

I don't remember my UCSD email address, but some years later, I was part of the admin team on the major UUCP hub hplabs, and my email address was simply hplabs!taylor. Somewhere along the way, networking leaped forward with TCP/IP (we had TCP/IP "Bake Offs" to test interoperability). Once we had many-to-many connectivity, it was clear that the "bang" notation was unusable and unnecessarily complicated. We didn't want to worry about routing, just destination. Enter the "@" sign. I became taylor@hplabs.com. Meanwhile, UNIX kept growing, and the X Window System from MIT gained popularity as a UI layer atop the UNIX command line. In fact, X is a public domain implementation of the windowing system my colleagues and I first saw at the Xerox Palo Alto Research Center. PARC had computers where multiple programs were on the screen simultaneously in "windows", and there was a pointer device used to control them—so cool. Doug Englebart was inspired too; he went back to Stanford Research Institute and invented the mouse to make control of those windows easier. At Apple, they also saw what was being created at PARC and were inspired to create the Macintosh with all its windowing goodness. Still, who doesn't love the command line, as Ritchie and Kernighan had originally designed it in the early days of UNIX? (UNIX, by the way, is a wordplay on a prior multiuser operating system called Multics, but that's another story.) Read more

Python Programming Leftovers

GNU/Linux Leftovers

  • USB Support In Chrome OS 75 Will Make Linux Incredibly Versatile
    Chrome OS Linux instances are on the cusp of becoming immensely more useful and versatile based on a recent change spotted by Keith I Myers in the beta-specific Developer Channel following an update to version 75.0.3759.4. That's because while the update inevitably introduced some new bugs that will need to be squashed before a final release, it also included full support for USB devices on the Crostini side of the equation.
  • Old computer? Linux can give it a new lease on life
    The operating system is called Linux and was created in 1991 by Finnish student Linus Torvalds. He released Linux as open source which meant that any good programmer could tinker with it and improve upon the original. Today Linux is a popular free alternative for Windows and Mac computers and used by millions of people. The beauty is that Linux requires much less processing power and memory than Windows and is perfect for older computers.
  • At Least 27% Of Gentoo's Portage Can Be Easily LTO Optimized For Better Performance
    entooLTO is a configuration overlay for Gentoo's overlay to make it easy to enable Link Time Optimizations (LTO) and other compiler optimizations for enabling better performance out of the Gentoo packages. GentooLTO appears to be inspired in part by the likes of Clear Linux who employ LTO and other compiler optimization techniques like AutoFDO for yielding better performance than what is conventionally shipped by Linux distributions. The GentooLTO developers and users have wrapped up their survey looking at how practical this overlay configuration is on the massive Portage collection.  The initial GentooLTO survey has been going on since last October and they have collected data from more than 30 users. The survey found that of the Gentoo Portage 18,765 packages as of writing, at least 5,146 of them are working with the GentooLTO configuration.
