ʻO nā ʻōlelo papahana kakaʻikahi a me ka pipiʻi loa. Mahele II

I kēia mau lā, no ka poʻe heluhelu Habr, ua alakaʻi au i kahi pōkole aʻo nā ʻōlelo hoʻolālā e like me Rust, Dart, Erlang, e ʻike i ke ʻano kakaikahi o lākou i ka mākeke IT Lūkini.

I ka pane ʻana i kaʻu noiʻi, ua ninini ʻia nā manaʻo a me nā nīnau e pili ana i nā ʻōlelo ʻē aʻe. Ua hoʻoholo wau e hōʻiliʻili i kāu mau manaʻo āpau a hana i kahi loiloi hou.

Ua komo ka noiʻi i nā ʻōlelo: Forth, Ceylon, Scala, Perl, Cobol, a me kekahi mau ʻōlelo ʻē aʻe. Ma keʻano laulā, ua kālailai au i 10 mau ʻōlelo papahana.

I mea e maʻalahi ai ʻoe e ʻike i ka ʻike, ua hoʻokaʻawale wau i nā ʻōlelo i ʻelua mau pūʻulu: ʻaʻohe koi (ʻaʻohe koi a haʻahaʻa haʻahaʻa) a kaulana (ua koi ʻia ka ʻōlelo ma ka mākeke IT Russian).

ʻO kaʻu loiloi, e like me ka manawa hope loa, ua hoʻokumu ʻia ma ka ʻikepili i lawe ʻia mai ka portal Headhunter, mai ka ʻoihana pūnaewele LinkedIn, a me nā helu pilikino mai koʻu ʻoihana. No ka nānā pono ʻana i nā ʻōlelo laha ʻole, ua hoʻohana au i ka lawelawe Amazing Hiring.

No ka poʻe ʻike ʻole i ka Amazing Hiring, e haʻi aku wau iā ʻoe. He lawelawe kūikawā kēia e "parses" i nā ʻike āpau e pili ana i nā loea mai nā wahi āpau o ka Pūnaewele. Me kāna kōkua, hiki iā ʻoe ke ʻike i ka nui o nā loea e hōʻike i kahi ʻōlelo kūikawā i kā lākou mākaukau.

No laila, e hoʻomaka kākou me nā ʻōlelo papahana kaulana.

Nā ʻōlelo kaulana

ʻO Verilog, VHDL

Ua kaulana loa kēia mau ʻōlelo wehewehe ʻenehana nui ma ka mākeke IT Lūkini. Ua hōʻike ʻia nā loea 1870 ma Headhunter ua ʻike lākou iā Verilog. Hoʻihoʻi ka hulina VHDL i 1159 hoʻomaka hou. 613 nā loea i kākau ma nā ʻōlelo ʻelua. ʻElua mau mea hoʻomohala i hoʻokomo i ka ʻike o VHDL/Verilog ma ke poʻo inoa o ka hoʻomau. Hoʻokaʻawale, ʻike ʻia ʻo Verilog ka mea nui - 19 mea hoʻomohala, VHDL - 23.

Aia he 68 mau hui e hāʻawi ana i nā hana i nā mea hoʻomohala i ʻike i ka VHDL, a me 85 no Verilog. ʻO kēia mau mea, he 56 ka nui o nā hakahaka. Ua kau ʻia nā hakahaka 74 ma LinkedIn.

ʻO ka mea mahalo, kaulana nā ʻōlelo i waena o nā poʻe ʻōpio ʻōpio mai 18 a 30 mau makahiki.

No ka hui pinepine ʻana o VHDL a me Verilog, hōʻike wau i ka ratio pili o ka helu o nā hoʻomaka i ka helu o nā hakahaka me ka hoʻohana ʻana i ka laʻana o ka ʻōlelo VHDL. No ka maopopo, ua hoʻokaʻawale wau i nā mea hoʻomohala i hōʻike i ka ʻike o VHDL ma ke poʻo inoa o kā lākou hoʻomau, hiki ke ʻike ʻia ma ke kiʻi:

Hōʻike ke kiʻi i ka ratio o ka helu o nā hakahaka i ka helu o nā hoʻomau i paʻi ʻia. Hōʻike ʻia nā mea hoʻomohala o ka wehewehe ʻenehana VHDL i ka ʻulaʻula.

Scala

Malia paha kekahi o nā ʻōlelo kaulana a ʻimi ʻia ma ka papa inoa. Ua komo ka ʻōlelo i nā ʻano helu like ʻole Stackoverflow. He 18 ia ma ka papa inoa o nā ʻōlelo kaulana loa. ʻO ia kekahi o nā ʻōlelo punahele ma waena o nā mea hoʻomohala ʻōlelo, e lawe ana i ka 12th wahi i ka pae a, ʻoi aku hoʻi, ua helu ʻia ʻo Stackoverflow iā Scala ʻo ia kekahi o nā ʻōlelo papahana ʻoi loa. Aia ka ʻōlelo ma hope koke o ka ʻōlelo papahana Erlang, e lawe ana i ke kūlana 8. ʻO ka uku awelika honua no kahi mea hoʻomohala Scala he $ 67000. Ua uku nui ʻia nā mea hoʻomohala Scala ma USA.

Ma Headhunter, ua hoʻokomo nā loea 166 i ka ʻike o Scala i ke poʻo inoa o kā lākou hoʻomaka. Ua paʻi ʻia ka huina o 1392 resume ma Headhunter. Ua kaulana loa kēia ʻōlelo ma waena o nā ʻoihana ʻōpio. ʻO ka maʻamau, hele ʻo Scala ma hope o Java. Aia he 2593 e hoʻomaka hou ana ma Linkedin, a ʻo 199 nā mea hoʻomohala Scala.

Inā mākou e kamaʻilio e pili ana i ka noi, ʻoi aku ka maikaʻi o nā mea āpau ma ʻaneʻi. Aia he 515 mau hakahaka ikaika ma Headhunter, a he 80 ka nui o Scala i helu ʻia ma ka inoa hakahaka. Aia nā hui 36 e ʻimi nei i nā mea hoʻomohala Scala ma LinkedIn. Ma ka huina, hāʻawi nā hui 283 i nā hana no nā kāne ʻike iā Scala.

Hōʻike ke kiʻi i ka ratio o ka helu o nā hakahaka i ka helu o nā hoʻomau i paʻi ʻia. Hōʻike ʻia nā mea hoʻomohala Scala i ka ʻulaʻula.

Ma waho aʻe o ka makemake o nā mea hoʻomohala Scala ma ka mākeke Lūkini, loaʻa iā lākou nā uku kiʻekiʻe. Wahi a kaʻu helu ʻoihana, ʻoi aku ke kumukūʻai o nā mea hoʻomohala Scala ma mua o nā mea hoʻomohala Java. Ke ʻimi nei mākou i kahi mea hoʻomohala Scala no kahi hui Moscow. ʻO ka uku maʻamau i hāʻawi ʻia e nā mea hana i waena o nā loea pae waena e hoʻomaka mai 250 tausani rubles.

Iā Perl

ʻO ka mea "pinepine" ma kaʻu papa inoa o nā ʻōlelo laha ʻole ʻo Perl. ʻOi aku ma mua o 11000 mau loea IT i helu i ka ʻike o Perl ma ke ʻano he mākaukau nui, a ʻo 319 o lākou i hoʻokomo i ka ʻike o ka ʻōlelo ma ke poʻo o kā lākou resume. Ma LinkedIn ua loaʻa iaʻu he 6585 mau loea i ʻike iā Perl. Aia he 569 mau hakahaka ikaika ma Headhunter, 356 ma LinkedIn.

He liʻiliʻi nā mea hoʻomohala i hoʻokomo i ka ʻike Perl i ke poʻo inoa o kā lākou hoʻomau ma mua o nā hakahaka i paʻi ʻia. ʻAʻole ʻo Perl he ʻōlelo kaulana wale nō, ʻo ia kekahi o nā ʻōlelo i makemake nui ʻia ma ka mākeke. Penei ke ano o ka helu helu:

Lakeponahelu Stackoverflow e hōʻike ana ʻo Perl kekahi o nā ʻōlelo papahana ʻoi loa (ʻo ka awelika honua he $69) a ʻo kekahi o nā mea kaulana loa i ka honua. ʻOi aku ma mua o 000% o nā mea hoʻomohala e ʻōlelo iā Perl.

ʻOiai ke kiʻekiʻe kiʻekiʻe o ka ʻōlelo, hāʻawi ʻia nā mea hoʻomohala Perl i nā hana e nā papahana i noho lōʻihi ma ka mākeke IT. I nā makahiki ʻekolu i hala iho nei, ʻaʻole i loaʻa i kaʻu ʻoihana kahi noi e ʻimi i kahi mea hoʻomohala Perl no kahi papahana IT hou a hoʻomaka paha.

Heluhelu:

Inā mākou e hoʻohālikelike i ka noi no nā ʻōlelo papahana kaulana a pau, loaʻa iā mākou kekahi mea e like me kēia: ʻo ka ʻōlelo kaulana loa i waena o nā mea i hoʻohana ʻia ʻo Perl. He 925 ka nui o nā hāʻawi hana ma HeadHunter a me LinkedIn no ka poʻe ʻike iā Perl. ʻAʻole mamao ʻo Scala ma hope o Perl. Aia nā makana 798 ma nā puka.

Hōʻike nā kiʻi i ka helu o nā hakahaka i paʻi ʻia no nā ʻōlelo hoʻonohonoho: VHDL, Scala, Perl.

Nā ʻōlelo papahana laha ʻole

Kekahi

Ua ʻike ʻia ka ʻōlelo papahana Forth i nā makahiki 70. I kēia manawa ʻaʻole ia i koi ʻia ma ka mākeke Lūkini. ʻAʻohe wahi hakahaka ma Headhunter a i ʻole LinkedIn. Ua hōʻike ka poʻe loea 166 ma Headhunter a me 25 ma LinkedIn i kā lākou mākaukau ʻōlelo ma kā lākou hoʻomau.

ʻO ka hapa nui o nā mea noi i ʻoi aku ma mua o 6 mau makahiki o ka ʻike hana. Ke noi nei nā poʻe loea me ka ʻike o Forth i nā ʻano uku like ʻole mai 20 tausani rubles a hiki i 500 tausani rubles.

Cobol

ʻO kekahi o nā ʻōlelo papahana kahiko loa. ʻO ka hapa nui o nā mea hoʻomohala he mau ʻelele o ka pūʻulu ʻelemakule (ma luna o 50 mau makahiki) me ka ʻike hana hoihoi. Hōʻoia pū kēia i ka helu hope loa Stackoverflow, ʻo ia ka mea i kākau ʻia e ka hapa nui o nā mea papahana ma Cobol a me Perl.

I ka huina, loaʻa iaʻu he 362 hoʻomaka hou ma Headhunter a he 108 hoʻi hou ma LinkedIn. Ua hoʻokomo ʻia ka ʻike Cobol o nā loea 13 i ka inoa hoʻomaka. E like me Forth, ʻaʻohe hāʻawi hana i kēia manawa no ka poʻe ʻike iā Cobol. Hoʻokahi wale nō hakahaka ma LinkedIn no nā mea hoʻomohala Cobol.

Rexx

Kūkulu ʻia e IBM a hiki i ka piko o kona kaulana i ka makahiki 90, ua lilo ʻo Rexx i kēia lā ʻo ia kekahi o nā ʻōlelo liʻiliʻi loa ma kaʻu papa inoa.
Ua helu nā mea hoʻomohala 186 i ka ʻike o Rexx ma kā lākou Headhunter hoʻomaka hou, a me 114 ma LinkedIn. Akā naʻe, ʻaʻole hiki iaʻu ke ʻimi i nā hakahaka no Rexx ʻike ma kekahi o nā puka puka.

ʻO Tcl

He koi no ka ʻōlelo, akā ʻaʻole wau e hoʻokaʻawale i ka ʻōlelo e like me ke koi. He 33 mau hakahaka ma Headhunter a he 11 ma LinkedIn. ʻAʻole kiʻekiʻe loa ka uku i hāʻawi ʻia i nā kāne me ka ʻike o "Tikl": mai 65 tausani rubles a 150 tausani. Ua hōʻike ʻo 379 mea hoʻomohala ma Headhunter a me 465 ma Linkedin ua ʻike lākou i ka ʻōlelo. Hoʻokahi wale nō mea hoʻomohala i helu i ka kuleana o Tcl ma ke poʻo o kāna resume.

ʻO kēia ke ʻano o ka ratio o ka helu o nā hakahaka i ka helu o nā hoʻomau i loaʻa ka mākau Tcl e like me:

Clarion

ʻAʻole au i ʻike i nā hana ikaika e koi ana i ka ʻike no Clarion. Eia naʻe, aia kahi manaʻo. Ua hōʻike ʻia nā kānaka 162 ma LinkedIn ua ʻike lākou i kēia ʻōlelo, a ma Headhunter - 502 mau loea, a ʻekolu o lākou i hoʻokomo i ke akamai i ke poʻo inoa o kā lākou resume. Ua loaʻa iā Amazing Hiring he 158 mau loea i kamaʻāina i ka ʻōlelo Clarion.

Ceylon

Hoʻokumu ʻia e Red Hat i ka makahiki 2011. Ma muli o Java. No laila ka inoa o ka ʻōlelo: ʻike ʻia ka mokupuni ʻo Java ma ke ʻano he mea hoʻolako kope, a ʻo ka mokupuni ʻo Sri Lanka, i kapa ʻia ʻo Ceylon ma mua, ʻo ia ka mea hoʻolako kī ma ka honua.

Kakaʻikahi maoli ka ʻōlelo. ʻAʻohe wahi hakahaka a ʻaʻohe hoʻomaka hou. Ua loaʻa iā mākou kahi hoʻomaka maoli ma Headhunter. Hāʻawi ka lawelawe ʻo Amazing Hiring i nā loea 37 wale nō ma Rūsia.

Heluhelu:

Inā hoʻohālikelike ʻoe i nā ʻōlelo ʻokoʻa a pau e ka helu o ka hoʻomaka ʻana, loaʻa iā ʻoe nā helu helu hoihoi: ma LinkedIn, ʻo ka poʻe loea i hōʻike i ka ʻike o Tcl, a ma Headhunter, ʻo Clarion ka ʻōlelo kaulana loa ma ka papa inoa. ʻO ka ʻōlelo kaulana loa ma waena o nā mea hoʻomohala ʻo Cobol.


Ua hōʻike ʻia kaʻu loiloi liʻiliʻi ua lilo ʻo Ceylon i ka ʻōlelo laha loa; ʻaʻohe koi a me ka lako i ka mākeke IT Lūkini. ʻO nā ʻōlelo laha ʻole pū kekahi me Forth, Cobol, Clarion, Rexx. Ua lilo ʻo Perl a me Scala i mau ʻōlelo kaulana a kaulana. Hiki ke hoʻoneʻe ʻia lākou mai ka papa inoa o nā ʻōlelo papahana laha ʻole.
