The era of DTrace

The kernel debug printf thread discussed recently on opensolaris-code forum raised interesting things. Inspired by Mike Shapiro mail I started to rework all my DEBUG cmn_err() in the Bluetooth prototype into DTRACE_PROBEn() calls. At some point I realized that there is no need for DTRACE_PROBEn() calls at all. Exactly like Mike suggested - all the necessary data processing can and should be done externally in the accompanying D-script. I have to admit it was quite a revelation for me. I think only now I start to comprehend the real power of DTrace and I am sure there will be more plesant surprises on the way.

So, good bye cmn_err() - you served me well, but it is a new era of DTrace !

Which repositories are there ?

opensolaris.org lets [OpenSolaris] projects host their repository there. However, there is no easy way to find out which repositories are there. Unless, ofcourse, project leaders announce the repo to some mailing list or so. There is, nonetheless, another way to find all of them - visit root of the OpenSolaris source browser site - it will show you what they've got there in all gory details.

SXCR b52 seems to be available

Solaris Nevada (aka SXCR) build 52 seems to be available for download.

Interesting (and addictive) brain exersize

Got this stuff from a friend. Solving it was a funny experience!

And it brings a bunch of new packages:

Live ON Mercurial Repository

Great work ! The ON consolidation made another step towards migrating to Mercurial SCM. The live Mercurial mirror of the Internal TeamWare gate is available for [RO] anonymous access at ssh://anon@hg.opensolaris.org/hg/onnv/onnv-gate. Kudos to stevel, dduvall and all the others involved in creating the infrastructure and making it happen !

365 days of OpenSolaris uptime

Well, 365 days full of interesting discussions, heated debates, creating a mindshare, forming a community - building OpenSolaris to what it is today. I am very proud to be part of it.

From my part these 365 days were filled (with no particular order) with:

1. Contributing a very first non-Sun bug fix to ON consolidation.

2. Contributing to Polaris project - some may remember a burst of posts this winter in the press on OpenSolaris/PPC kernel being built. While the meaning of this was quite exaggerated by the press it was a big step none the less.

3. Taking care of OpenSolaris Subversion repository.

svn:/export/home/imp> uptime
1:50am up 365 day(s), 3 users, load average: 0.00, 0.00, 0.00
svn:/export/home/imp>

which is breaking a 365 days uptime barrier today together with OpenSolaris !

4. Trying to find time to put more life into Israel OpenSolaris User Group.

Yesterday evening I found that I even was nominated for OpenSolaris Contributor Award!

So, happy birthday OpenSolaris, congratulations to all the community members - everyone of us put something into what we have today, so let's celebrate!

Polaris community site has arrived

Polaris Community site if finally up and running. It took some time to figure out which software to run there and where to host it and after a month of preparation it is now operational. Kudos to Craig and Dennis for making it happen.

The software we run there allows us to have a wiki, a ticket management, a simple project management, etc - I feel very much impressed with the overall quality of it. Good stuff! I am surprised I never heard about Trac before...

ASCII Art Forever !

James Dickens just posted a funny "vi" upgrade picture and I remembered that many years ago I came across a Star Wars Episode IV in ASCII. Yes, the movie in ASCII Art ! You were to telnet to some host and it was then played on your terminal. So I google for it "ASCII Star Wars" and it immediately showed me a modern (aka Java, aka Web-friendly) version of this masterpiece.

So, here it comes - http://www.asciimation.co.nz/

Storage Community went live !

Rainy evening at Murphy's

It was rainy yesterday evening, but it didn't stop us - John Plocher, Leon Koll and myself - from getting together at Murphy's pub in Herzelia marina. Place was quite crowded - people were gathering there to watch the basketball game later that evening on the big screens around the pub. So we had to wait some time while the staff were figuring out where to sit us. The good thing is that we've got the first round of beer on house for standing patiently :) Too bad Leon showed up a little later and missed that.

Anyway, if you ask me - pub is one of the best places to have good technical talk :)
