Re: [9fans] Darksky
we do all seem to be working on the same things.

I haven’t tried rebuilding flickrfs recently, but it still gets at my flickr account (just tried it). I had forgotten that it was related. My next target is Twitter. I saw a blog post that you were working on a dropbox thingie at some point; you ever get anywhere with that?
Re: [9fans] Plan 9 BOF at Usenix with a slight difference
I can't make it, but I'd be most appreciative if someone who can attend would record this talk Ron. Either way, I'm excited to hear more! -joe On Thu, Jun 25, 2015 at 11:54 AM, ron minnich rminn...@gmail.com wrote: I'm giving a talk at Usenix in Santa Clara in 2 weeks on u-root, and I'll be setting up a Plan 9 BOF (assuming there is room) with a difference: we're going to demo the GPL'ed Plan 9 code base booting on a small amd64 cluster (assuming it's working by then!). The system is built with gcc, although some of us are advocating moving to clang. A full build of all libraries, binaries, and kernels takes about 2-3 minutes. It's now possible to debug the kernel, including setting breakpoints and examining structures, with gdb when you are running under qemu. If you're at Usenix drop on by and see what you think.

Re: [9fans] p9p's stats

On 2015-06-25T19:25:36+0200, Nils M Holm wrote:
When logging in via ftpfs, though, I get an empty /n/ftp directory.
Turns out that ftpd on FreeBSD announces a port on localhost for
passive mode connections:
227 Entering Passive Mode (127,0,0,1,247,55)
If I understand QEMU user networking correctly, it sees incoming
traffic as originating from localhost, in which case the above
would make sense.
So I patched ftpfs and added an additional command line option to
ignore the host address part of the above message and substitute
the destination system's address.
The patch works fine for me. I'm not a networking expert, though,
so it may have some subtle side effects that I'm not aware of.
The patch is below in case anybody is interested.
Thanks for your help!

[9fans] Basic limbo programming help
Hello fellow 9fans! I'm currently trying to learn limbo programming for fun and profit. I'm experienced in java and other languages, but I'd like to learn limbo because I want to (wait for it, drumroll please!) build a distributed agent-based system. The agents themselves aren't anything complicated; I've already written a prototype in java. However, limbo offers a vastly superior communications system than java (and windows for that matter), so I believe inferno is going to be a great choice in the desired platform. However, first thing's first, is learning the language. So, I'm reading A descent into Limbo. And the first program example runs fine. However, the second, the graphical hello world, does not. I'm having a problem with the line: t := tk-toplevel(ctxt.screen ); The compiler is telling me that screen isn't a reference of ctxt, and it expected display instead. But if I change the reference from context to display, well... It will compile and run, but I don't get a button. The example pictures show a different inferno button than what is in the current version, so maybe it's an outdated example? Or is ctxt really the author telling me don't copy and paste, think about what goes here! Because I'm finding those hinted in other example codes as well. So, if there are any limbo programmers out there, would you mind giving me a hand? Thanks!
Re: [9fans] p9p's stats
nstats in my contrib as promised. its a slightly modified port of russ's code from p9p that uses a GUI frontend and an OS specific backend. I added the OS type and a rough performance guide to the top line (if the window is wide enough) as we had quite a few servers on different OSs and it was very helpful to be able to put the system load in context. I have used this code extensively but not widely - there may be portability issues I have missed. As usual feel free to feed back fixes and extensions. -Steve
