recommend gadgets for brad! [Nov. 11th, 2000|08:10 pm]
Brad Fitzpatrick
Ate dinner. Still tired. Might read a book later.

For now, I invite everybody to help me in a little research project. I want to buy three new gadgets, and I need recommendations on which to get.

1) Digital Camera -- my old one broke, an Epson PhotoPC 600, and I need a new one. Looking for: Compact Flash (I hate Sony Mavicas... no offense, evan), takes pictures quickly, looks professional (no gimmicky Kodaks with cartoon menus... no offense, dad).

2) MP3 Player -- never owned one. Looking for: more than 64 MB of memory, or one that takes Compact Flash (I love Compact Flash's form factor and low cost). Must be able to show long file names and/or ID3 tag info. I don't want one that plays CDs too ... I already have a discman. I don't want moving parts.

3) Scanner --- my parents have one, blythe has one, sarah let me borrow hers most the year my freshman year ... i need my own finally. All too often I need to scan things and can't. Looking for: flat bed, Hewlett Packard (preferred), 8.5x11" (minimum and maximum), high DPI, parallel port or SCSI interface .... USB would be okay, but I'd prefer if it weren't.

It's been awhile since I did research into any of these categories of products, so any and all information will be much appreciated. :-)

Re: BSD/OS

Very good reasons.

I took an operating systems course and enjoyed it quite a bit.

How hard to you find to port things to BSD/OS? How activity is the community?

Re: BSD/OS

Well, I should have made one thing clear earlier: I work for a company which makes its own real-time embedded network operating system. It's distantly derived from BSD/OS, but we've taken great pains to ensure complete compatibility, at least with userland apps, and iBCS2 compliance.

It's that OS that I speak of. It's certainly something I do with a passion. I'm involved in the lower level stuff usually - drivers, stack optimizations for packet flow, and vm/paging/scheduling - though we strive to eliminate overspecialization.

And we're very active indeed in developing our OS. It's proprietary, which is something sadly needed in order to ensure market share (there are some really big entities in this area), but the answer to how hard it is to port code to BSD/OS and to our OS is "it depends."

If the (userland) code's been written with some semblance of POSIX.1 or POSIX.4, it's fairly trivial. Even drivers are easy to port over if the spec is clear. The problem is when people get too hacky. (e.g. a certain project which emulates concurrency in userland threads by setjmp()/longjmp() across "virtual-concurrent-control-threads.")

At any rate, this is probably not the right forum to get into this in gory detail. We should meet up some time and generally geek out.

Re: BSD/OS

Interesting.

Yes, a geek out is definitely in order.
