What pointless thing are you doing right now?

Well, currently I'm trying to save a program (ie cassette - audio in) to my indy via soundeditor and then reload it back into my MSX.
The recording works fine, and I can relive the wonders of the 1980's but having difficulty reloading it back.

What other pointless things are you doing?

1) Reading up on emulator design from http://www.codeslinger.co.uk/
2) Making a patch set to GemRB latest version with MIPSPro compiler. I'm at 82% done now.
3) Thinking what to do with an MFM RLL disk i found in an old shipping box at work.

Well some stuff aren't quite pointless, but hugely entertaining. :o

Nothing much. Finishing up glueing a Monroe 325 Scientist calculator back together that USPS did a number on and wondering if I should plan a 500 mi trip to pick up a PDP 11/44 and stuff.

Other than answering this post?-) Unifying all my tripod heads to Arca-swiss (a grand total of two). I also just finished moving my on-line photo collection to iSCSI rather than NFS because windows (which runs the raw developer) is shit at NFS. The iSCSI target is a file (on a level 5 raid), mounted RO locally on the host machine via (vnd and fuse and) ntfs-3g so the photos can be fed individually to backup tape rather than pulling the entire filesystem image every time (bacula doesn't do block-level differentials AFAIK). Works great.

Modifying a hot plate to use on the still I'm making. :twisted:

Building pkgsrc on Solaris, finally, and trying to find a bug in my TMS9995 emulation for my Tomy Tutor emulator.

Planning on writing an emulator, or just interested in how they work?

Ha ha, you guys are all cooler than shite... 8-)

So I found an Nvidia Quadro FX 3000G lying around at work, I brought it to the IT guys and they said I could have it because they would just throw it in the recycle bin, now admittedly this thing is old but HP sold it for $3000 back in the day, and it's got a genlock and full multisystem visualization and multidevice film and video environment skills, so I'm hoping I'll be able to get it working with my Octane and Tezro VBOB's for doing... Really Cool Stuff. Anyway it took me all day to get it running on my Slackware machine because the Nvidia driver source code has to be hand hacked to get it to work with modern Linux kernels (like mine) that no longer support the acpi_remove_notify_handler() function call, and who's bright idea was it to remove that from the kernel source anyway? Some crazy ass crackers are saying Linus did it deliberately because he hates Nvidia, and, by extension, any Linux users who use Nvidia products. :roll:

Mainly interested in the different techniques of emulating CPU's, although my main motivation for reading up is to help make emulating SGI machines a reality. Fortunately, MIPS emulation is relatively straightforward and several emulators already have been written. The hard part is the ASIC's surrounding the core, but that's not different from many other systems.

The problem I've found is a distinct lack of R10k/R12k/R14k/R16k CPU emulators, which means more work required in order to support Octane or Origin (including Fuel and Tezro as Origin variants). I suppose O2 or Indy support might be possible in the context of QEMU, though.

So, what pointless thing am I doing right now? Reading fiction instead of writing some code to load an Octane PROM, map it into some semblance of an address space, and start simulating instructions. Which has been on my to-do list for a week now, sidelined partly by work and partly by reading fiction.

We might want to spin off a new topic for emulation stuff (another emulation topic?) if we want to continue on this line. And if you are aware of any R10k type CPU emulators, please let me know. It might save me a pile of work. (-:

Reading Being and Nothingness . Quite relevant for this thread.

Just spent a couple of hours figuring out why my G5 no longer talked to the outside world ( I could ping internally). Resetting the PRAM took care of the problem and now I'm surfing the web and looking for PPC software I can install. I was able to download Blender 2.63a and get it working, now I just need to learn blender.

Ha. I'm on my G5 surfing Nekochan. That's pretty pointless. ;)
