@GergelyOrosz @AbdelOufkir1 @Lanooba I was part of that fintech team when I joined Uber and remember you visiting the WeWork we were at. Stop by the new office next time. :-)

I’ve been scrolling on Twitter for 15 years. No end in sight.

[Johan Mena @jhnmn]

This Twitter ads outage is the best kind of outage.

[Johan Mena @jhnmn]

Will somebody save this company from irrelevance?

[Johan Mena @jhnmn]

Still keep Twitter near and dear to my heart, and would dearly like to see it succeed.

The company will need a special kind of engineering talent with enough institutional knowledge to cut through mountains of complexity in *every part of the stack*: product, infra, ops…

[Johan Mena @jhnmn]

At Uber, we maintain a handful of popular Go libraries like zap, tally and cadence. It’d be ecstatic if Copilot could auto suggest code to write efficient zap serializers for my structs, for example.

[Johan Mena @jhnmn]

Copilot looks super interesting.

I wonder how well it would work with libraries. I imagine popular open source libraries would benefit a ton.

I can’t believe it’s only $10/month.

[Gergely Orosz @GergelyOrosz]

Many of the same software engineers mocking GitHub for charging $10/month for an advanced AI code completion tool that took years to develop would join an ML startup in a heartbeat to build another AI tool: where people would have even less willingness to pay anything for it.

[Johan Mena @jhnmn]

@danluu Where do I go to learn about these kinds of investments opportunities?

[Johan Mena @jhnmn]

I grossly underestimated the amount of effort it takes for big tech cos to move thousands of engineers to patch 0-day like log4j’s. If the tooling is not there, prepare to spend many hours just thinking about the corner cases you missed across your *entire stack*.

[Johan Mena @jhnmn]

Perf season: the mad scramble for impact.

[Johan Mena @jhnmn]

That went by FAST.

students are starting to steal each other's notes with iOS 15 and it's... kind of genius

[Johan Mena @jhnmn]

Update: Wau did not disappoint! Please stop me from spending all my money here.

[Johan Mena @jhnmn]

I’m very much super duper hyper excited to check out this place! Malaysia has some of the most delicious food I’ve tried.

"We noticed that on the Upper West Side people actually stayed," says Michelin-star chef Sahlil Mehta, who opened the Malaysian restaurant Wau with his wife, Stacey Mehta. "So we signed the lease here at the peak of the pandemic, and Wau was born." https://t.co/5Z9r8snOXK

A perfectly fine example of a git commit message from today.

im just out here tryna pay the bills python.

[Johan Mena @jhnmn]

I’ve been thinking about a lot of things recently. But the thing I’ve been thinking about the most is rate limiting technology.

[Johan Mena @jhnmn]

Two artists I’ve been obsessed with recently:

1. Paul Kalkbrenner
2. Chilly Gonzales

[Wendell Pierce @WendellPierce]

The depth of my love for this brother, can only be matched by the depth of my pain learning of his loss. A immensely talented man with the ability to give voice to the human condition portraying the lives of those whose humanity is seldom elevated until he sings their truth.

[Johan Mena @jhnmn]

@Gothamist Xi’an is so good people break in at night to try to cook their own damn dumplings. I miss having one next to work.
