Does plan9 support 15 different archs with all of their quirks and subarchitectures? no. only 11
WiFi stack? yes, and bluetooth
Support for different power modes? yes, I think so, can't say I've ever used it. does "echo blank > /dev/vgactl" count?
Framebuffers? no, it is a 21st century os
Kernel probes, high resolution timers, extended inbuilt security APIs? yes
all in 13 syscalls

it's called "the Unix philosophy". invented by Doug McIlroy, probably before you were born
I thought goople app engine didnt allow outgoing connections

Using URL Fetch
When your application uses the URL fetch API to make an HTTP request, the development web server makes the request directly from your computer. The behavior may differ from when your application runs on App Engine if you use a proxy server for accessing websites.
Linux, fuse
there's your problem. it's not designed for it
> If anything, a microkernel is always more bloated because of the extra code needed to do all the process sync.
there are more than two types.
We have fretted recently because the plan9 kernel is struggling to fit on a floppy disk when loaded up as an installer with most things turned on.
The whole of plan9, kernel, userspace, 386 binaries & sources for 6 architectures fit into 200Mb uncompressed (and the whole shooting match compiles in 15 minutes).
Linux is a re-implementation of an OS that was already considered dead by it's maintainers.
"Not only is UNIX dead, it's starting to smell really bad." Rob Pike circa 1991.
see also "Sometimes when you fill a vacuum, it still sucks."
I wouldn't use Fuse as your benchmark. All of plan9's filesystems are userspace (except the one that uses a dedicated machine). They can saturate 10gbe so your objections really concern Fuse and it's hosts.
That's "President Obama".
thats right, bloat
filesystems dont belong in the kernel.
My operating system is open source but I bought it. What kind of software is it?
instead he's killed us all
700 years ago there were two million people in my country, now 60,000,000+
still close enough to search for things.

bah google changed their uri scheme
no, just providing more info, the author linked to Bentley's text for further reference so I was filling in the back story.
how about "what postcode am I in"? when out and about.
also "click on the map, what's the postcode?"
quite handy for getting the area code i.e N1
Only if you buy into it.
We were on Windows 2000 until this year finally moving to XP for multi-media compatibilty (specifically Flash) reasons.
I've been around since dos3.3, looking forward to upgrades went out of the window a long time ago :)
The only interesting hardware innovation in recent times has been an interest in reduced power consumption / back to passive cooling.
Then again, I'm a guy with a 486 upgraded to P54C with 32Mb RAM as my email server.
Bentley built his Markov chain using his Bell labs colleagues Pike & Kernighan's Markov algorithm from The Practice of Programming
http://books.google.co.uk/books?id=to6M9_dbjosC&pg=PA62&...
Pike had used this technique earlier when coding up http://en.wikipedia.org/wiki/Mark_V_Shaney with Bruce Ellis
I'm sure they were not the first
Did you read to the bottom? They wanted to generate not only valid output from valid makefiles but wanted to catch the same errors in the same way as their reference.
I like their approach and I would consider it an excellent bug hunting tool. Focussed fuzzing.
Would you consider their markov chained output a derivative work though ?

A light metre is 1 / 299 792 458 or 3.33 x 10e-11 seconds
how do you measure mental pain?
Markov chaining bach is also interesting

use it in unicode mode, that kills performance
my friend works digitising film stock.
He told me that a Portuguese tv station is deteriorating and the fumes it gives off spreads the process to the other film stock and even if they had all the 35mm film digitisers in the world running 24/7 they would still lose a significant portion so they are having to make some tough decisions about what to save.
oh and it was Bell-Labs that invented pixels.

Python used to be available as a client side scripting language for EMCA but I can't find that project these days.
The Limbo programming on the Inferno OS makes great use of co-routines. http://www.vitanuova.com/inferno/

I copy the data arenas to another machine and when they are full (500mb per arena) I burn them to cd.
I us this script to copy the arenas
http://plan9.bell-labs.com/sources/contrib/maht/rc/vbackup
It's slightly sloppy in that I could just append the unwritten bytes but for < 500mb who cares, its a 1gbe after all.
Venti dumps give me a full history of file changes. On the plan9 central server one can browse the daily snapshots for 10+ years of plan9 development. It also coalesces duplicate blocks so storing 20 copies takes as much room as one.
Venti is available for plan9 and Lunix.
