Mostly tech, startup, finance stuff. Now: recreational programming, trading stonks

Sometimes I just love programming because of the unexpected little things that make me laugh, and I'm not being sarcastic

@ShameVincent @JeremiahDJohns Doesn't seem that hard to understand?: You don't want to compare a cohort with "mostly families" to a cohort with "mostly single adults living alone" because then the relative incomes would be pretty meaningless

@ClaudiuDP @ThePrimeagen Why say this about Tobi? It's not exactly a secret he wrote code for the shopify platform, and was one of the early members of the ruby on rails core team

@patio11 this is obviously a troll post? nobody writes a rejection email summarizing each step they put the candidate through

2016 & 2025 with @yukihiro_matz

(@hsbt thanks for the picture!)

[Peter Cai @pcai_]

@_st0012 @yukihiro_matz @hsbt congrats!

@ZachariahSchwab @besttrousers He literally opened by explaining the problem - it's *not* a similar picture - it goes *down* during unemployment spikes

It's just measuring ratios about how old the bathwater is, it tells you nothing you wouldn't already know by measuring stocks and flows directly

So excited and honored to be speaking at SF Ruby conf in November! I’ll be talking Realtime with Rails, Anycable and Yjs! Hope to see you there!

[Peter Cai @pcai_]

Pretty good showing from Boston at #railsconf so @APIguy insisted we all get a photo together

[Peter Cai @pcai_]

It’s kind of petty but if a candidate sends me a resume titled resume.pdf…

I just know its not gonna be a fit

@jeremysmithco Have you seen https://t.co/S2cUVTprOq

@JasonSwett Have you read sapiens? I’m sure you have thoughts

[Peter Cai @pcai_]

@JasonSwett Eh. I’d argue it’s more like a kitchen staff. A film crew doesn’t get to iterate on feedback. A good restaurant staff is continuously tweaking the menu and way it works in response to customer feedback.

[Peter Cai @pcai_]

@JasonSwett Counter point - I’ve been at companies with very well defined job levels where people could be SWE I for a decade, and this was just accepted as a possibility

[Peter Cai @pcai_]

@APIguy @bostonjsmeetup @flexcar Meetups are so back

[Peter Cai @pcai_]

@thedayisntgray Signed up too, thx for posting

[Peter Cai @pcai_]

Many US engineers want full remote jobs and are also anti offshoring but what’s the argument? What’s the game plan when all the jobs that can be done remote are offshored? :(

[Jason Swett @JasonSwett]

I bought a bunch of books on eng management. They were written by devs. Sadly, but not surprisingly, they all sucked.

Then I bought The Effective Executive by Peter Drucker. Astonishingly great!

IME often the best programming wisdom is found outside the software industry.

Let's talk if you're ready to make this the hardest, most impactful (and most rewarding) work of your career.

Reposting some news: I'm starting at Sigma Squared as VP of Engineering.

I'm especially excited to help the company enter a new vertical in law enforcement. Law enforcement agencies everywhere have been inundated with nonsense statistics that confuse disparity with bias.

[Peter Cai @pcai_]

for enterprise HR, retail, and now law enforcement & more. We're going to succeed no matter what, but it'll go easier with some help: we're hiring across multiple departments including engineering in Cambridge - but know that this won't be a leisurely walk in the park.
