#qi-hardware IRC log for Wednesday, 2014-12-17

wpwrakDocScrutinizer05: so ... has the rigol arrived and you're in no-sleep-until-2014 mode now ? or did you pass out waiting for oops ? :)03:45
wpwrakerr .. until 201503:45
DocScrutinizer05it arrived at 18:00 and I gave it 50min test then had a nap09:15
DocScrutinizer05and earned a terrible headache, which I won't blame to UPS or Rigol but rather to weather09:48
DocScrutinizer05btw it just was o'scope and accessories (bnc-4mm adapters, Rigol-softbag), the DMM and related accessories completely postponed to week5/201509:49
DocScrutinizer05maybe some poor chinese dude has to manually erase all the Agilent signs and replace them by Keysight09:50
DocScrutinizer05>> U1173A  Adapter Infrarot zu USB  fürHandmultimeter U125x-Serie obsolete, ersetzt durch U1173B, abwärtskompatibel<< and the complete lack of any *1173* product on that shop website open up room for speculations09:52
DocScrutinizer05btw I actually started looking at desktop-DMM but they are waaaay more expensive, mostly thanks to starting at 5 digits09:55
DocScrutinizer05they are generally calibrated and that costs $$$09:55
DocScrutinizer05my operation mode in lab is based on a "nothing is calibrated, except my own logic which is 99.999999999% true" - so I really don't need expensive calibrated gear. I don't do certification stuff where I need to check operational limits 09:58
DocScrutinizer05worst case convenient "calibration" normals are available everywhere. 1V5 primary cell, 230V AC, etc10:00
DocScrutinizer05all my probing usually is a go/nogo type of data acquisition which often has 30%/70%/130% thresholds and for such even a 5% "accurate" DMM is absolutely fine10:02
DocScrutinizer05btw c't mag goes foolish: "Heft 2 (TWO!!!) 2015 erscheint ab 2014(!)-12-27 am Kiosk"10:13
DocScrutinizer05I wonder how long until I read issue 1/20XX in summer of 20$(( XX - 1 ))10:14
Action: DocScrutinizer05 watches Rigol 1054Z auto-calibrate, gripped10:42
DocScrutinizer05some of them translations to english are a tad... unusual. using "printscreen" the scope shows a short remark "Disabled Some Operations!" ... OK. But after completing the save-to-USB process it shows a remark "Can Operate Now" which really puzzled me if this device is maybe from medical/surgery domain ;-)11:09
DocScrutinizer05http://wstaw.org/m/2014/12/17/plasma-desktopz11330.png   :-))11:25
wpwrakDocScrutinizer05: Nuernberg is a big city. takes UPS guy all day to make his rounds ;-)12:58
DocScrutinizer05HATE!!!! http://wstaw.org/m/2014/12/17/plasma-desktops11330.png12:59
wpwrakIRC port is open,. interesting. didn't think they knew their customers *that* well  :)13:00
DocScrutinizer05I wonder what EU is worth for when they can't even enforce astronomically high penalty tax on all products that do not support alternatives to redmond crap13:01
wpwrak(bench dmm) yeah, for me it's mainly to get more sensible current measurements and the convenience. i don't send my critters in for re-calibration.13:01
DocScrutinizer05http://wstaw.org/m/2014/12/17/plasma-desktopz11330.png turns out to be absolutely useless since best you can do is configure the IP stack of the rigol. NOTHING else13:03
ysionneauthat's not very funny ...13:05
ysionneau(rigole in french is laugh)13:05
wpwrakysionneau: still better than the famous Toyota MR2 ;-)13:06
DocScrutinizer05http://www.lxistandard.org/  feels like I'm in for another waste of time13:06
ysionneauwpwrak: mr2 -> shit ?13:07
wpwrakysionneau: of course :)13:07
ysionneauyes nice as well13:07
ysionneaubut less obvious than rigol13:07
ysionneaumaybe depends on how you pronounce it :p13:07
DocScrutinizer05Pachero, or Pajero13:07
DocScrutinizer05akso Toyota?13:08
wpwrakysionneau: and then there's always the Mitsubishi Pajero ... that one doens't lack clarity :)13:08
DocScrutinizer05https://translate.google.com/?hl=de#es/de/pajero  >>Definitionen von pajero  Adjektiv  [persona] Que se masturba con frecuencia.<<13:10
Action: ysionneau just discovered what Pajero means13:10
ysionneauI thought it meant "bird" but no :p13:11
ysionneauthat's pajaro13:11
ysionneaupcercuei: are you french?13:12
larscwpwrak: or the Rolls-Royce Mist13:50
viricDocScrutinizer05: yes, that's why in Spain it's called Montero13:50
DocScrutinizer05only officially, my spanish friends told me. People still call it Pajero13:57
DocScrutinizer05now you see why Siemens pays signifacant fractions of a million for new product names. "Sony" been the result of iirc 12 months of worldwide studies and several millions spent on them. The name "Sonny" sounded weird in Korea or dunno where13:59
DocScrutinizer05that's why trademarks/names are high value assets for comapnies14:00
DocScrutinizer05though I guess Mitsubishi won't ask many $$ to sell "Pajero"  X-P14:01
Action: DocScrutinizer05 glares at Rigol DS1054Z, wonders how to flash firmware and if that would reset the options (prolly not)14:02
wpwrakDocScrutinizer05: so you "upgraded" it ?14:04
DocScrutinizer05pondering to do. But no upgrade without decent rollback strategy14:05
wpwraklarsc: brought to you by the truth in advertizing board ;-)14:05
larscwhat do you call a hypercube that is fully contained within another one with the same number of dimensions? sub-cube?15:00
viricinner hypercube15:01
larscok, thanks15:02
wpwraklarsc is gift-wrapping ;-)15:03
larscin 7 dimensional shoe cartons ;)15:06
larscActually I'm working on a bit of ALSA documentation15:12
DocScrutinizer05ALSA and hypecibes?15:15
DocScrutinizer05hypercubes* dang!15:15
Action: DocScrutinizer05 wonders if larsc tries to describe the ALSA audiostack plugin concept15:16
DocScrutinizer05take care, "lower" layers of stack might as well have more 2dimensions" than upper ones of same stack15:17
wpwrakyou can tell things are going well when a document begins with "for simplicity, we assume a galois field of hypercubes in N-space, with N >= 4, for which we define ..."15:23
larscI see you did you research ;)15:30
DocScrutinizer05dang, I checked wikipedia galois field15:30
whitequark"the inherent amusement of the phrase simple complex Lie algrbra"15:31
