Umbhalo obhaliwe ohunyushwe

Kuhunyushwe kusuka ekulandiseni kokuqala kwesiNgisi. Umsindo namazwibela atholakalayo alawulwa yi-YouTube.

0:00 Inkampani yokuhweba ithumela ikhodi entsha kumaseva ayisikhombisa kwawayo ayisishiyagalombili, futhi owesishiyagalombili uthenga futhi athengise amasheya acishe abe ngamaRandi ayizigidi eziyizigidi eziyisikhombisa emizuzwini engamashumi amane nanhlanu, okuningi, ngisho nangosuku Lwesithathu. Agasti 1, 2012. I-Knight Capital, ingxenye yeshumi yayo yonke i-U.S. ukuhweba ngamasheya, ibika ukulahlekelwa kwamaRandi ayizigidi ezingama-440. I-SEC kamuva ibala ngaphezu kwama-460, ihlawulise i-Knight izigidi eziyishumi nambili, futhi izibhalela i-postmortem ngokwayo: amakhasi ayishumi, iziphawulo eziyisishiyagalombili.

0:25 Kuhleleka kanjani, kungani kungenzeka, futhi ubani ngempela olahlelwa icala. Lona yi-The Daily Diff, i-postmortem. Julayi 27. I-New York Stock Exchange yethula uhlelo lwemali oluncane kubantu abaningi ku- Agasti 1, ngakho i-Knight ikopisha ikhodi entsha ku-SMARS, i-router yayo yama-oda, amaseva ambalwa ngosuku, ngesandla. Uchwepheshe oyedwa, amaseva ayisishiyagalombili, amakhophi ayisikhombisa. Akekho ohlolayo; akukho mthetho othi kufanele kube khona. 8:01 a.m. Uhlelo lwangaphakathi luqala ukuthumela abasebenzi i-imeyili yephutha elifundeka kanje: I-Power

0:51 I-Peg ikhutshaziwe. Ama-imeyili angamashumi ayisishiyagalolunye nane ngaphambi kokuvulwa. Ayiklanyelwe njengezixwayiso, ngakho akekho oyifundayo, okuyisinqumo sokuklama esinenani. 9:30, imakethe iyavula. Amaseva ayisikhombisa asebenzisa ikhodi entsha. Owesishiyagalombili ubona ifulegi elifanayo bese esebenzisa i-Power Peg esikhundleni salokho: ikhodi i-Knight eyayiyithathe umhlalaphansi ngo- 2003 futhi ingalokothi isuswe. Ithumela ama-oda ezingane ngama-oda ekhasimende angu-212, futhi ayilokothi ime.

1:13 Ukwenziwa okuyizigidi ezi-4. Amasheya ayizigidi ezingama-397. I-akhawunti yokubamba ikhula idlule umkhawulo wayo wamaRandi ayizigidi ezimbili, okungaxhunyiwe lutho. Onjiniyela, emakethe ebukhoma, bakhipha ikhodi entsha kumaseva amahle ayisikhombisa, okushintsha i-Power Peg kuyo yonke indawo. Cishe ngo-10:15 iyama: amabhiliyoni amathathu nengxenye isikhathi eside, amabhiliyoni amathathu kanye nemihlanu esikhathini esifushane.

1:31 Okokuqala: Isimo sokumisa se-Power Peg, isibali esithi i-oda lomzali li- ligcwalisiwe, lathuthelwa ngo-2005 futhi lingalokothi lihlolisise kabusha, ngakho ikhodi ethatha umhlalaphansi ijalika ingunaphakade. Okwesibili: isici esisha sisebenzisa kabusha ifulegi elidala le-Power Peg, ngakho yebo efanayo isho izinto ezimbili kumaseva amabili. Okwesithathu: akukho nkinobho yokubulala. Akukho okuqhathanisa ama-oda aphumayo nama-oda angenayo; akukho okumisa i-SMARS. I-risk monitor isikrini esibukwe abantu; ayibonisi imikhawulo. I-git blame: ifulegi elisebenziswa kabusha esikhundleni esisha, ikhodi efile esebenza iminyaka eyisishiyagalolunye,

2:00 futhi ukuthunyelwa ngesandla okungenalo ipheya lesibili lamehlo. Hhayi uchwepheshe. I-oda le-SEC alilokothi limqambe ngegama, nami ngeke. Ububanzi bokuqhuma: amaRandi ayizigidi ezingama-460, cishe izigidi eziyishumi ngeminithi. Amasheya ehle ngo-63% kuya kumadola amabili namashumi amahlanu nesishiyagalombili, ukutakula okungu-$400M ngedola elilodwa namashumi amahlanu ngesheya, ukuhlanganiswa ne-Getco ngaphambi kukaKhisimusi. I-Hacker News, uLwesine: kwenzeka kanjani ukuthi iqhubeke imizuzu engama-45 ngaphandle kokungenelela komuntu? Akuzange. Abantu benza kwaba kubi kakhulu.

2:25 Isahlulelo, i-postmortem: buyisela emuva. I-Knight ayilokothi izibhalelwe i-postmortem yayo; isilawuli siyenza, ezinyangeni eziyishumi nane kamuva, futhi ukulungiswa yinhlawulo nokuhlanganiswa. UMsombuluko: isici esisha, ifulegi elisha; ikhodi efile iyasuswa, hhayi ukukhubaza; noma yini ethumela ama-oda ithola iswishi yokuvala. Ngithumele isigameko ongakavunyelwa ukukhuluma ngaso, kumazwana, noma ku-daily diff dot dev. Futhi yilokho umehluko wanamuhla.

2:48 Ngingu-Niko ovela ku-Axrisi. Hlanganisa ngokuzibophezela.
