Mind sageli kritiseeritakse t\u00f6\u00f6l \u00fche kummalise omaduse p\u00e4rast \u2013 m\u00f5nikord viibin liiga kaua \u00fclesande kallal, olgu see juhtimis- v\u00f5i programmeerimise \u00fclesanne, mis tundub lahendamatuna. Tundub, et on juba ammu aeg loobuda, minna j\u00e4rgmise juurde, aga mina ikka nokitsen ja nokitsen. Selgub, et asi ei ole nii lihtne.<\/p>\n

Lugesin siin \u00fchte imelist raamatut, mis k\u00f5ik j\u00e4lle selgitas. Mulle meeldib selline asi \u2013 sa tegutsed kindlal viisil, see toimib, ja siis \u2013 bam, leiad teadusliku selgituse.<\/p>\n

L\u00fchidalt, selgub, et maailmas on v\u00e4ga kasulik oskus \u2013 lahendada lahendamatuid \u00fclesandeid. Just siis, kui ei tea, kuidas seda lahendada, kas see on \u00fcldse v\u00f5imalik. K\u00f5ik on juba ammu loobunud, kuulutanud \u00fclesande lahendamatuks, aga sina \u2013 nokitsed kuni l\u00f5puni.<\/a><\/noindex><\/p>\n

Hiljuti kirjutasin arusaamisest teadlikkuse kohta, kui \u00fchest v\u00f5tmekvaliteedist, mis minu arvates on programmeerija jaoks oluline. Noh, see ongi see. Mitte loobuda, otsida, proovida variante, l\u00e4heneda erinevalt, kuni \u00fclesanne l\u00f5puks ei katke.<\/p>\n

Sarnane omadus, nagu mulle tundub, on v\u00f5tmekvaliteet ka juhiks. Isegi veel olulisem kui programmeerija jaoks.<\/p>\n

On olemas \u00fclesanne \u2013 n\u00e4iteks, kahekordistada efektiivsuse n\u00e4itajaid. Enamik juhte ei p\u00fc\u00fcagi seda \u00fclesannet lahendada. Lahenduse asemel otsitakse p\u00f5hjuseid, miks seda \u00fclesannet \u00fcldse ei peaks t\u00f5statama. V\u00e4ljaated k\u00f5lavad veenvalt \u2013 v\u00f5ib-olla, kuna \u00fclemusel, ausalt \u00f6eldes, ei ole ka tegelikult tahtmist seda probleemi lahendada.<\/p>\n

Niisiis, mida raamat selgitas. Selgub, et lahendamatute \u00fclesannete lahendamine arendab oskust lahendada lahendatavaid \u00fclesandeid. Mida rohkem ja kauem sa nokitsed lahendamatute kallal, seda paremini suudad lihtsamaid \u00fclesandeid lahendada.<\/p>\n

Jah, muide, raamat kannab nime \"Tahtej\u00f5ud\", autor on Roy Baumeister.<\/p>\n

Ma olen sellisega juba lapsep\u00f5lves tegelenud \u00fcsna proosalisel p\u00f5hjusel. Elasin 90ndatel maal, oma arvutit mul ei olnud, k\u00e4isin s\u00f5prade juurde m\u00e4ngima. Ja, mingil p\u00f5hjusel, armusin seiklustesse. Saadaval olid Space Quest, Larry ja Neverhood. Aga internetti ei olnud.<\/p>\n

Tollased seiklused ei ole kellegi praegustega v\u00f5rreldavad. Esemed ekraanil ei olnud heledalt esile toodud, kursoreid oli viis \u2013 st. igale esemele sai reageerida viie erineva viisiga, ja tulemus oli erinev. Kuna esemed ei olnud esile toodud, siis polnud pixel hunting'i (kui liigutad kursori \u00fcle kogu ekraani ja ootad, kuni midagi esile kerkib).<\/p>\n

L\u00fchidalt \u00f6eldes, olin seni, kuni mind koju ei saadetud. Aga k\u00f5ik \u00fclesanded sain tehtud. Siis ma hakkasin armastama lahendamatuid probleeme.<\/p>\n

Siis t\u00f5in selle praktika programmimise peale. Varem oli see t\u00f5eline probleem, kui minu palga suurus s\u00f5ltus \u00fclesannete lahendamise kiirusest \u2013 aga ma ei saa niimoodi, mul on vaja s\u00fcveneda, m\u00f5ista, miks see ei toimi, saavutada vajalik tulemus.<\/p>\n

Seda olukorda p\u00e4\u00e4stis tehas \u2013 seal oli p\u00f5him\u00f5tteliselt \u00fcksk\u00f5ik, kui kaua sa \u00fclesande kallal oled. Eriti, kui oled ainus programmeerija ettev\u00f5ttes ja pole \u00fclemust, kes t\u00e4htaegadest meelde tuletaks.<\/p>\n

Aga n\u00fc\u00fcd on k\u00f5ik muutunud. Ja ma, ausalt \u00f6eldes, ei m\u00f5ista inimesi, kes j\u00e4\u00e4vad pidama 1\u20132 iteratsiooni juures. Kui nad kohtavad esimest takistust, nii nagu k\u00e4ed longu. Nad ei proovi isegi teisi v\u00f5imalusi. Lihtsalt istuvad ja k\u00f5ik.<\/p>\n

Osaliselt rikub pilti internet. Kui miski ei \u00f5nnestu \u2013 jooksu google'i. Meie aegadel pidid sa ise hakkama saama, v\u00f5i ei olnud mingit v\u00f5imalust. No maksimaalselt k\u00fcsisid kellegilt. Aga maal ei olnud eriti keda k\u00fcsida \u2013 j\u00e4lle, sest su suhtlusring on interneti t\u00f5ttu piiratud.
\nPraegu aitab lahendamatute probleemide lahendamine t\u00f6\u00f6s palju. Sisuliselt ei tule variant, et loobun ja ei tee, isegi mitte m\u00f5tteisse. Siin on, minu arvates, p\u00f5him\u00f5tteline k\u00fcsimus.<\/p>\n

Tavaks lahendada lahendamatut sunnib lahendust otsima, aga selle tava puudumine sunnib leidma \u00f5igustusi. No v\u00f5i ema kutsuma igas arusaamatuses.<\/p>\n

See ilmneb eriti isikuhalduses. Tavaliselt on n\u00f5udmisi, millega algaja t\u00f6\u00f6taja kas vastab v\u00f5i ei vasta. V\u00f5i seal on ettevalmistusprogramm, mille tulemustest s\u00f5ltub, kas inimene sobib v\u00f5i ei sobi.<\/p>\n

Aga mulle on see \u00fcksk\u00f5ik. Ma tahan igast inimesest programmeerijat teha. Lihtsalt n\u00f5uetele vastavuse kontrollimine \u2013 liiga lihtne. See on lahendatav \u00fclesanne. Isegi sekret\u00e4r suudab sellega hakkama saada. Aga muuta t\u00fcvest Buratino \u2013 see on jah. See on v\u00e4ljakutse. Siin tuleb m\u00f5elda, otsida, proovida, eksida, aga j\u00e4tkata.<\/p>\n

Nii et ma soovitan siiralt lahendada lahendamatuid \u00fclesandeid.
