Loading solaris sar data to MySQL

Sar (System Activity Report) is the performance data collector on all unix systems. If it works pretty well to collect data, displaying the result lets a bitter taste; forget any colorfull graphs, its output is only tabs of pure ascii text. However, sar's weakness is also his strength; text is easy to parse and Unix have plenty of powerfull tools to do so. My aim today is to parse the output of sar and to load it into MySQL. Why MySQL? Simply because it's a powerfull free database, and querying MySQL with Excel is easy. The idea is simple: sar > XML > LOAD XML command > MySQL database Step 1 - choosing the output of sar On Solaris, sar -A provides all the results; actually, it is equivalent to successively issue these commands: sar -u (CPU utilization) sar -d (activity for each block device) sar -q (average queue length while occupied) sar -b (buffer activities) sar -w (system swapping and switching activity) sar -c (system calls) sar -a (file access system ro...

Restoring a Dell Dimension 1100

I purchased it a while ago, second hand but almost new. It then left home during my broke up, and was recently given back, with its 17" CRT. Dusty and no HDD (my ex kept her secrets), but worthed a restore; the idea was to replace the old Toshiba laptop I use for Cubase. Cleaned up, memory boosted to 1 Gb, SSD and IDE-to-SATA converter, ready to go. I first tried Windows 7, but the lack of compatible video driver forced me to go back to XP. Well, it's a pretty good OS after all, still in use in many places. Once all drivers set, the Dell works pretty well and quite fast. My workhorse sequencer is Cubase SX 2.2, wich was released in the same years; with 1 Gb RAM, it's large enough for my needs. Because I lack a descent audio I/O so far (I use my Novation XioSynth as I/O; I wich to purchase a friend's unused I-ONIX), I mainly use it for MIDI. With twice the horsepower and 4 times the memory (and room to double), it's a good step ahead from my Toshiba. A good p...

ARP Omni repair

Hi there. Long time. Last summer, I bought a non working ARP Omni. Powered up: no sound but a small glitch. Here is what I've done to fix it. Deep cleaning. Vacuumed first, then I pull all the board off and bath them. Yes, in water with soap and an old tooth brush to gently scrub. Rinced and thorough dried them with common a hair-dryer. Cleaned the Pratt-Reed keyboard. Cleaned the casing. Sanded the wood ends and sprayed some Pledge. Looks nice now. Check the PSU; every thing was OK in this department. At that time, I had no scope. My first guess was a dead output op-amp. Replaced, but still dead. Suspected the 4007 on upper board; replaced it. Still no sound. Got a small digital oscilloscope (116 $ incl shipping and taxes). Upper Voicing Board. Check the output of main osc: OK, outputs of MK50240: Ok. Checked the 4069s and found 2-3 dead gates. Replaced the dead 4069. Ground was shorted to -15V on Upper Voicing Board. Once forced to 0V, could produced some...

Jean Naty-Boyer a bercé mon enfance

Comme ça, d'un coup, m'est revenu en mémoire quelques mots d'une chanson apprise durant le CE2 (8 ans) : "conte la Seine aux indifférents...". Quelques googleries plus tard, j'apprends que l'auteur est Jean Naty-Boyer, agé de 79 ans, à qui on doit plus de 400 chansons pour enfants. Dont le célèbre "Boris et Natacha" (Dans la forêt blanche d'Ukraine ...). Autrement dit, on a tous une chanson de Naty-Boyer logée quelque part dans la tête, mais il est curieux de constater qu'il n'existe pas un site qui lui est dédié, pas même une page wikipedia...Faut corriger ça.

La tortoche et le gibelot

Ça sert à rien d’se grouiller… Faut prendre un bon départ Comme disait la tortoche au gibelot, l’air peinard. « -Tiens ! J’te joue une tune que j’te gratte au poteau, Malgré mes p’tits panards et toi tes grands pinceaux. -T’es cinglée, qu’y lui fait, t’as une poussière dans l’œil… Les 2 doigts dans l’tarin, j’gagnerais dans un fauteuil. Tu s’rais même pas parti que j’s’rais déjà au bistro… -Que dalle ! fait la tortoche. Tiens, j’te joue l’apéro. » Et les paris s’engagent. 60 contre 1, voilà l’gage. Le kangourou, qui s’marrait, dit : « c’est moi que j’fais l’starter ! ». Y file sa pogne dans sa fouille, en sort son revolver Et Pan ! les v’là partis. Ou plutôt la tortoche, parce que l’gibelot, y’s’dit : « -J’suis pas encore loquedu, y’a l’bourguignon qui tape, j’partirai à la fraîche En mettant l’grand braquet… J’m’en vais griller une sèche. » Y s’installe, fait son pieu, glisse sur la moleskine, Pique un p’tit roupillon… et la tortoche , elle s’débine Sans s’frapper, vers le but. Quand ...
