DOSBox ported to google’s Chrome as NACLBox!

This is cool.  While it won’t be portable like jdosbox, it should run significantly faster.  At the moment there is some bugs in a port of SDL to the NACL framework, but when they get those worked out it’ll be amazing!

And I have to wonder with a real i386 backend and SDL would Qemu on NACL be possible? And the ability to sync disk images somewhere for persitent storage, and you’d get a ‘web os’ of your choice, on demand!

At a minimum it’d be cool to compare neko in a ‘native’ version of dosbox.

Sysadmin rosetta stone.

A friend passed this link on to me, and it’s a good place to turn for some old/foreign OS’s.

It’s covers some basic tasks with the following OS’s:

  • AIX
  • A/UX
  • DG/UX
  • FreeBSD
  • HP-UX
  • IRIX
  • Linux
  • Mac OS X
  • NCR Unix
  • NetBSD
  • OpenBSD
  • Reliant
  • SCO OpenServer
  • Solaris
  • SunOS 4
  • Tru64
  • Ultrix
  • UNICOS

Always a good thing to have handy if you run into a supercomputer…..

Looks like more outages ahead..

“We’re moving most of our servers from SVTIX[1] to Market Post Tower[2] this
weekend. we’ve got layer 2 between the two locations already, so we’ll
be bringing down servers in batches of five and moving them five at a shot.
each user should experience something like two hours of downtime, if all
goes well.”

Well at least luke is transparent on the whole thing so it looks like there will be more bumps ahead. But I do have a full backup so worst case I can bring this online elsewhere if this goes down.

If anything the blogger outage made me finally break down and get that squared away.

As always, I’ll have win32 builds up in the usual spot.  i386/x86_64 and everything else.  I’ve tested these on Windows 7 x86_64, and they should work on XP & Vista i386 as well.

Also I’ve switched this to 7zip to save space.

 

So this VM walks into a bar…

He looks at the selection, and is impressed, they have virtually everything he could ever imagine.

OK, I saw this shamelessly come through on google…
And I must admit, I really don’t have one.  But I did find a funny picture in an ancient OS/2 SDK, from Microsoft…

Heh.  Then again zippy the pinhead was quite popular in the 80s.
Yow!  Did something bad happen or am I in a drive-in movie??

Which sure does remind me of stuff like this…

Whole lot of virtualization going on!

Emulators in emulators, in emulators in emulators… (XP in Virtual PC, Windows 95 in Qemu, MacOS in Mini vMac, MS-DOS in SoftPC)..  It reminds me of  Inception

Arduino: Core memory for your pc

A picture of Arduino core memory

Arduino Core memory shield

While the site, corememoryshield.com is more so geared to making your own, they do provide the information needed to build your own core memory…

One has to wonder if in the future, some kids will struggle to get a hard disk working, or perhaps attach DRAM to a pc…

Then again I am pretty sure that SIMH, emulates machines that most certainly used core & drum memory…
