Recently I got to know Jeff, who holds up half the programming world.
I’ve confirmed with him personally,
and indeed it matches the legend,
so I record this here.

  • Jeff and Ehco are both developers at Shanbay, but Ehco left after a while, because Mr. Shuijing said the two of them together would too much affect this version’s balance.
  • Jeff is Shanbay’s core developer. Part of his work is changing the word cards for vocabulary-learning users.
  • Shanbay doesn’t support German because Jeff hasn’t found time to learn German.
  • Shanbay launched programming courses because Jeff discovered he had spare capacity to teach programming.
  • In Shanbay programming, when students don’t understand they ask the TA, when the TA doesn’t understand they ask the Shanbay engineer, when the engineer doesn’t understand they ask the CTO, when the CTO doesn’t understand he files a ticket to Jeff, and Jeff handles them in priority order when he has time.
  • Shanbay has no production incidents, because Jeff writes the post-mortems ahead of time and then fixes them ahead of time.
  • The few Shanbay outages were because Jeff was binging variety shows and forgot to handle frontend requests.
  • Jeff watches all variety shows in his spare time.
  • The TV variety shows in “Rick and Morty” were created under Jeff’s guidance.
  • Whenever Kim Tae-ho and Na Young-seok have arguments, they go to Jeff for the final ruling.
  • Jeff occasionally helps Xiaomi TV optimize variety show pages.
  • The 48 in AKB48/SNH48/NMB48 is Jeff’s weight, representing his weight in the group.
  • Jeff’s recent wish is for Eru Kanda to film a variety show, while Ehco is waiting for season 2 of Dragon Maid.
  • Ehco was called Echo when he was little, but he later changed the name on his ID card himself.
  • Shanbay’s wrong-answer book is handled by Ehco for the return values.
  • After AbnerLee worked with Ehco, he figured out his software should be called Typora.
  • Ehco can write 31 letters on a US keyboard.
  • Ehco only needs 1 hour to do the work of others’ 8 hours. The extra 7 hours are spent fixing spelling mistakes. True story.
  • When Ehco writes frontend, he likes to start from the obfuscated version, because that way variable names are shorter and harder to misspell.
  • Ehco’s database skills are so masterful that he generally only uses for to solve problems, not MAX or MIN functions.
  • But Ehco and Jeff’s joint debugging has also had problems, because Jeff returns values too fast, and Ehco hasn’t had time to fix the typos yet.
  • Later Ehco slipped Jeff some sleeping pills, force-sleep-ing to solve this problem.
  • Ehco’s main work at PingCAP is adding titanium (Ti) to TiDB.
  • After TiDB changed its engine to Ehco, single-machine efficiency improved 200%, but Ehco temporarily doesn’t support high availability.
  • Under Ehco’s suggestion, Dai Jiawei started livestreaming Hearthstone as “Yilingshu” (Alien Spirit Art).
  • Ehco suggested designers add Jeff to Hearthstone, localized in translation as “Jeffries.”
  • When you make a wish to Jeff, he’ll do his best to grant your wish, but watch out for the Ehco next to him — be careful not to have it altered into other meanings via typos.
  • After all, I want to be rich and I want to be lich are one letter apart, a thousand miles off.
