Solaris Engineering - huge amount of technical stuff

As promised - Solaris engineers just have overhemled us with technical postings on their blogs! There's really huge amount of technical data posted just after the launch. Below are some links I collected (it will take a lot of time to read thru all of this) - I haven't catched all of them - you have to find them yourself.

update: Thanks to Liane Praza and Bryan Cantrill you can find more ordered list of some of the links below - here and here.

Something wonderful has just happened!

Finally Open Solaris is up!

You can download sources and compile them yourself! And it works! Several Pilot members, including me, have been doing that for some time. It's quite simple.

I've been involved with Open Solaris for several months now, as many other folks. It took a lot of time to open Solaris but they (we?) did it!

Solaris engineers prepared a little suprise on their blogs - so go to Sun's blog or better to Planet Sun which is a blog aggregator of Sun's blogs. I belive you would find there a lot of really interesting and technical staff about Solaris in a moment.

ps. I really love Source Browser - just try it!

Something's going to happen... Something wonderful...

I understand how you feel.

You see, it's all very clear to me now.

The whole thing.

It's wonderful.

Solaris SX build 16

I installed last night o my laptop latest Solaris Express which is based on Nevada build 16, so it includes new booting architecture on x86/x64 platforms. Here are screenshots (sorry for bad quality of these pictures).

Something's going to happen... Something wonderful...

Own Cluster Agents

Some overview on developing own cluster agents.

Voices of Open Solaris

"Most operating system reviews and developer interviews rely on technical points to explain what a project is about and what benefits users might derive from it. We rarely hear from the people responsible for the lion's share of the work in the open source software world. So here's a less technical interview with some members of the OpenSolaris development team."

Full interview here.

B52 drink

Some humor :)

New build of Open Solaris

I've just BFU'ed my system to Nevada build 16 of Open Solaris!

Sun Microsystems Inc.   SunOS 5.11      milek-b16       October 2007
bfu'ed from /tmp/nightly-nd/ on 2005-06-10

btw: Open Solaris is coming really soon now!

Solaris Security Toolkit 4.1

Formerly known as JASS. From System News:

"Designed to simplify and automate the process of securing Solaris Operating Systems, this toolkit is based on proven security best practices and practical customer site experience. It can be used to secure SPARCR-based and x86-based systems."

It's available for free here and documentation is here.

Monitor!

This is cool!

Messaging Server with SpamAssassin and ClamAV

I've just added support for ClamAV to spam_master.

What is spam_master? It's a small C program which allows Messaging Server to use SpamAssassin and ClamAV. It's not a clean code - but it works. You can download it here.

NVIDIA drivers for Solaris x86/x64

NVIDIA just released drivers for its video cards for Solaris X86. You have to modify /etc/driver_aliases to get it working with vide adapters which are not officially supported by Sun. And yes, it supports OpenGL!

Compare by hash

Really interesting paper comparing hash functions efficiency with compression and diffs. Definitely worth reading even for sys admins (you can find there some interesting remarks abour RSYNC).

btw: I have a little bit different version of the document with some minor differences when Val Henson was working for Sun.
And it looks like you can find more interestig papers on her page.
