Sure, we all know ZFS, but little chance is that you know RBAC, FSS or SMF. If you do know these, you probably won't know SamFS or JET. These are more obfuscated features of Solaris that are quite handy though.
LKFS aka the Lesser Know Solaris Features is a ebook by Joerg Moellenkamp about generally unknown commands and functionalities in (Open)Solaris.

The Russian volcano that erupted directly beneath the International Space Station on June 12th is now causing beautiful lavender sunsets across parts of the northern USA and Europe. A plume of ash and sulfur dioxide from the Sarychev Peak eruption is circulating through the stratosphere, and when parts of the plume pass over an area at sunset, the sky can be seen filled with delicate white ripples, sometimes-colorful streamers, and a telltale hue of purple.

Now that the milky way is getting high into the zenith with the accompanying constellations, an existing comet is getting back into sight. C/2006 W3 Christensen is visible as a hazy comet with a brighter core, and should reach magnitude 8 in the summer.

Het was ondertussen al 3 jaar geleden dat we ons nog eens lieten zien op TWClassic : in 2007 trok de affiche op geen bal, en verleden jaar hadden we teveel miserie aan onze kop. Maar dit jaar was de line-up toch wel sensationeel : Keane, Moby, Peche Démodé en Basement Jaxx zijn stuk voor stuk topgroepen die uiterst aangenaam festivalvoer zijn. Voor de rest : ruim 60 euri aan junkfood en booze, een marcelleke van StuBru (spot u ons Martine ?), een Proximus klak (Mobistar klanten moesten het met een belachelijke lanyard doen), en een jammerlijk gefaalde poging op een Randstad Duckie t-shirt.

Qua muziek niet te klagen, behalve dan Basement Jaxx. Tjonge, tjonge, wat een ontgoocheling; waar was de groep van 'Where's your head at?' ? In de plaats kregen we een wall of noise van drum-n-beat, gospel and r&b, die de weide in een mum van tijd decimeerde, en waardoor we hopeloos in de file terechtkwamen door het grote aantal vroeg vertrekkende festivalgangers.

We have a giant SL8500 tape library at work, which regularly needs to be fed. I once had the dull task of feeding the beast 600 tape media though the front-end CAP, at 14 media per time, which took me quickly about 4 hours to perform. Yesterday, we had a new batch of 300 tapes, which had to be entered. Luckily, the StorageTek technicians were present, doing a firmware upgrade of the library. As they opened the library for easy access of some vital parts, I took the chance of entering the machine, and putting the tapes in their slots from the inside.

A SL8500 is a U-shaped library, which can be entered from top of the 'U'. On the long sides, tapes reside on both sides, and on the curved side of the U, the tape drives are mounted. So I accessed the library in a narrow corridor of 2 meter tall walls, completely filled with tapes containing the precious electronic data of my enterprise. These corridors sure are narrow, so I guess one of the requirements of being a StorageTek admin is not having a Burger King subscription. I only hoped that the technicians didn't forget to deacivate the handbots, cause an encounter with a iron gripper, moving at 5 meters/second would definitively send me on a one-trip down to the cemetery.

The picture doesn't do the library right : in this dark corridor, only being lit by some faint LEDs, and with my crappy phone camera, only the lowest 50 centimeters are visible (I placed the camera on the floor). Imagine this being 2 meters high, and 15 meters long, and you have an idea what we're talking about.

I finished in an hour, and once the STK engineers had finished their labor, I let the library rescan its new inventory, which it finished within 3 minutes (I love StorageTek hardware). 450 new Terabytes ready to use. Happy munching, Optapemus Prime !
