\nJedn\u00edm z t\u011bchto nadm\u00edru technick\u00fdch lid\u00ed byl Mi\u0161a Basov. B\u011bhem let pr\u00e1ce v \"M\u011bge\" jsem o n\u011bm sly\u0161el mnoho dobr\u00e9ho a zaj\u00edmav\u00e9ho v tom smyslu, \u017ee st\u00e1l t\u00e9m\u011b\u0159 u samotn\u00fdch z\u00e1klad\u016f a spustil spoustu proces\u016f. S n\u00edm jsem se po\u0159\u00e1dn\u011b sezn\u00e1mit nedok\u00e1zal: potkali jsme se doslova na person\u00e1ln\u00edm odd\u011blen\u00ed, kdy\u017e jsem p\u0159inesl dokumenty a on je odeb\u00edral.<\/p>\n

Jeden z monitorovac\u00edch syst\u00e9m\u016f, se kter\u00fdmi jsme pracovali, byl naps\u00e1n Mi\u0161ou. U\u017e si moc nepamatuji, co se tam monitorovalo, ale v\u00edm, \u017ee Mi\u0161a napsal do\u010dasn\u00e9 \u0159e\u0161en\u00ed, kter\u00e9 se rychle stalo trval\u00fdm. A to je v po\u0159\u00e1dku: mnoho z toho, co prav\u00ed technici d\u011blaj\u00ed pro sv\u00e9 vlastn\u00ed pot\u0159eby na rychlo, se ukazuje jako skv\u011bl\u00e9. Ten monitorovac\u00ed syst\u00e9m tak\u00e9 v\u0161em vyhovoval, fungoval bez jak\u00e9koli podpory a \u00fadr\u017eby, pravda, nikdo nev\u011bd\u011bl jak.<\/p>\n

P\u00e1r let po Mi\u0161ov\u011b odchodu monitorov\u00e1n\u00ed za\u010dalo zobrazovat pr\u00e1zdnou str\u00e1nku.
\nOkam\u017eit\u011b jsem vyhl\u00e1sil poplach. Vedouc\u00ed sm\u011bny vyhl\u00e1sil poplach. Vedouc\u00ed sektoru vyhl\u00e1sil poplach. <\/p>\n

Vedouc\u00ed odd\u011blen\u00ed dal na poplach. Vedouc\u00ed slu\u017eby dal na poplach. Vedouc\u00ed odd\u011blen\u00ed zazvonil zvone\u010dky. Zvuk usly\u0161el IT \u0159editel cel\u00e9ho Povol\u017e\u00ed a okam\u017eit\u011b svolal poradu. Zavolal na ni vedouc\u00ed odd\u011blen\u00ed. Ten za\u0159val na vedouc\u00edho slu\u017eby.

Jednou, kdy\u017e jsem se vym\u011bnil na sm\u011bn\u011b, vyrazil jsem na tuto poradu.

\"P\u0159\u00edb\u011bhy
\nAnalyzujeme dal\u0161\u00ed \u201ep\u0159ehmat\u201c na sm\u011bnn\u00e9m st\u0159\u00edd\u00e1n\u00ed.<\/i><\/p>\n
Za n\u011bkolik let pr\u00e1ce zde si vzpom\u00edn\u00e1m na t\u0159i p\u0159\u00edpady, kdy n\u011bkoho z odd\u011blen\u00ed propustili.
\nJednou se in\u017een\u00fdr na no\u010dn\u00ed sm\u011bn\u011b rozhodl d\u00e1t si pivo, a v tu dobu do slu\u017eby vtrhl technick\u00fd \u0159editel. N\u011bkdy mohl takhle p\u0159ij\u00edt jednodu\u0161e pozdravit (jakoby on s\u00e1m za\u010d\u00ednal mezi slu\u017eebn\u00edky). Chytil kluka s plechovkou piva, klik na telefon, v\u00fdpov\u011b\u010f. U\u017e se nepilo pivo v noci.<\/p>\n
Jin\u00fdkr\u00e1t slu\u017eebn\u00ed oper\u00e1tor n\u011bjakou hodn\u011b stra\u0161nou nehodu pro\u0161vihnul. Podrobnosti u\u017e si nepamatuji.<\/p>\n
A pot\u0159et\u00ed \u2013 u\u017e ke konci m\u00e9 pr\u00e1ce tam. Pracovn\u00ed podm\u00ednky se velmi zhor\u0161ily, byl obrovsk\u00fd fluktuace a hrozn\u00e9 p\u0159es\u010dasy. Lid\u00e9 n\u011bkdy pracovali 24 hodin, pak \u0161li sp\u00e1t na 12 hodin a op\u011bt se vraceli na 24hodinovou sm\u011bnu. I j\u00e1 jsem tak pracoval, dokud mi to zdrav\u00ed dovolilo a bylo to placen\u00e9; pak prakticky p\u0159estali platit p\u0159es\u010dasy (standardn\u011b slibovali kompenzaci volnem, kdy\u017e bude p\u0159\u00edle\u017eitost \u2013 ale v\u0161ichni v\u011bd\u011bli, \u017ee nikdo nikdy nevyraz\u00ed), a na sm\u011bny n\u00e1s vyh\u00e1n\u011bli skoro hrozbami. Jednomu in\u017een\u00fdrovi to nevydr\u017eelo, vstal uprost\u0159ed sm\u011bny, ode\u0161el dom\u016f nav\u017edy, po cest\u011b nakoukl do kancel\u00e1\u0159e vedouc\u00edho slu\u017eby a poslal ho do h\u00e1je. Pamatuji si e-mailovou zpr\u00e1vu, v n\u00ed\u017e tohoto in\u017een\u00fdra zp\u011btn\u011b ozna\u010dili za fa\u0161istu a zr\u00e1dce, v ka\u017ed\u00e9 v\u011bt\u011b bylo c\u00edtit, jak to veden\u00ed toto jedn\u00e1n\u00ed roz\u010d\u00edlilo.<\/p>\n
Pokud jde o m\u00e9 osobn\u00ed chyby \u2013 jeden p\u0159\u00edpad si svou neobvyklost\u00ed zapamatoval. Op\u011bt no\u010dn\u00ed sm\u011bna, v\u0161echno ticho, nic se ned\u011bje. Na sm\u011bnov\u00e9 kontrole kontrolujeme monitoring: ups, v noci do\u0161lo k poklesu zpracov\u00e1n\u00ed dat ze switch\u016f, dobr\u00e9, \u017ee \u010derven\u00e1 kontrolka sv\u00edt\u00ed u\u017e dlouho. Celou noc jsem se d\u00edval na tento sign\u00e1l \u2013 a snad jsem ho nevn\u00edmal. I kdy\u017e to byl jeden z nejjasn\u011bj\u0161\u00edch a nejviditeln\u011bj\u0161\u00edch monitoring\u016f, st\u00e1le nech\u00e1pu, pro\u010d jsem to nevid\u011bl.
\nTady \u017e\u00e1dn\u00e9 v\u00fdmluvy ne\u0161lo uv\u00e9st, byla to \u010dist\u00e1 a stoprocentn\u00ed chyba, hav\u00e1rie p\u00e1t\u00e9 kategorie a velmi pravd\u011bpodobn\u00e9 propu\u0161t\u011bn\u00ed.

Proto\u017ee by nikdo nev\u011b\u0159il pravd\u011b, musel jsem si vymyslet n\u011bjakou poh\u00e1dku, \u017ee jsem kv\u016fli zran\u011bn\u00ed p\u0159ehnal s l\u00e9ky a usnul. \u0160\u00e9f slu\u017eby na m\u011b k\u0159i\u010del ve sv\u00e9 kancel\u00e1\u0159i, celkov\u011b to sm\u011b\u0159ovalo k propu\u0161t\u011bn\u00ed \u2013 ale vy\u00fastilo to v napomenut\u00ed s poklesem platu. Od t\u00e9 doby u\u017e n\u011bkolik let v Meg\u011b \u017e\u00e1dn\u00e9 bonusy nevid\u011bli, tak\u017ee jsem neutrp\u011bl \u017e\u00e1dnou ztr\u00e1tu.<\/p>\n
Kdy\u017e si vzpomenu na epizodu s p\u0159\u00edchodem technick\u00e9ho \u0159editele: jednou v noci se do slu\u017eby nahrnul n\u011bjak\u00fd chud\u00e1k a za\u010dal k\u0159i\u010det, \u017ee sed\u00edme nezamknut\u00ed (slu\u017eba by nem\u011bla b\u00fdt v z\u00e1sad\u011b zam\u010den\u00e1), \u017ee jsme tu idioti a \u017ee r\u00e1no od n\u00e1s o\u010dek\u00e1v\u00e1 vysv\u011btlen\u00ed v\u0161ech na\u0161ich chyb. T\u00edm chud\u00e1kem byl vedouc\u00ed bezpe\u010dnostn\u00ed slu\u017eby a od n\u011bj to bylo ZARAZ\u00cd. Po\u0159vav si, vedouc\u00ed ode\u0161el do tmy, a r\u00e1no jsme se zeptali na\u0161eho \u0161\u00e9fa \u2014 co m\u00e1me d\u011blat? \u201ePo\u0161lete ho do h\u00e1je\u201c \u2014 odpov\u011bd\u011bl a t\u00edm incident skon\u010dil.<\/p>\n
Jak jsem zni\u010dil odd\u011blen\u00ed<\/h4>\n
\nV t\u011bch dnech byl bashorg (tehdy je\u0161t\u011b bash.org.ru, a ne to, co je te\u010f) kultovn\u00edm zdrojem. Cit\u00e1ty se tam objevovaly skoro ka\u017ed\u00e9 dva m\u011bs\u00edce, a m\u00edt SVOU! CIT\u00c1T!!! NA BASHI!!! bylo stejn\u011b cool, jako m\u00edt vlastn\u00ed dom\u00e9nu druh\u00e9 \u00farovn\u011b v roce 2000. Tenkr\u00e1t byl bashorg v\u00edce IT-animovan\u00fd, ale byl vtipn\u00fd pro v\u0161echny.<\/p>\n
Ka\u017ed\u00e9 pracovn\u00ed r\u00e1no nejmlad\u0161\u00edho in\u017een\u00fdra (tedy m\u011b) za\u010d\u00ednalo \u010dten\u00edm bashorgu \u2014 t\u0159icet sekund sm\u00edchu p\u0159ed dvan\u00e1cti hodinami str\u00e1d\u00e1n\u00ed.<\/p>\n
Jednou se m\u011b kolega zeptal, \u010demu se to sm\u011bju. Uk\u00e1zal jsem mu, \u010demu. On rozeslal odkaz po odd\u011blen\u00ed.<\/p>\n
Pr\u00e1ce se na p\u00e1r dn\u00ed zastavila: k m\u00e9mu p\u0159ekvapen\u00ed nikdo z koleg\u016f o bash do t\u00e9 doby nev\u011bd\u011bl. Ve slu\u017eb\u011b se sm\u00e1li: \u201eAch-haha-haha, opravit KDE, haha-haha!\u201c. \u201eHihihi, utopit kl\u00e1vesy v rtuti, bgegege!\u201c. Pracovn\u00ed den byl ztracen, na druhou stranu \u2014 \u017eivot jsme si z\u00e1znamn\u011b prodlou\u017eili.<\/p>\n
