tldr; UCLA makes it extremely hard to share meal swipes, so I reverse engineered our school's internal API

Sharing meal swipes with your friends in UCLA sucks. Its a mess requiring the seller to manually placing orders, screen-record QR codes (screenshots are blocked), and then chase for payments.

Here's how I fixed it:
1. Used @charlesproxy as a MITM to map the internal backend API of our dining hall app.
2. Wrapped these endpoints in a simple UI.
3. Integrated @stripe for instant payments to the student selling the swipes.
4. The buyer gets their QR code immediately, no screen recording needed.

Now I can just purchase swipes from my friend without them having to actually do anything 🤷

@kylejeong holy shit this is so clean

✅ bucket list item complete: write an article on a tech blog!!

come read about distributed systems, memory pressure, thread parallelism and more!

Daft now has native distributed ASOF joins.
And it scales horizontally without data skew.

Distributed asof joins in v0.7.10 — temporal accuracy at any scale.

Match each trade with the most recent quote before its timestamp. Scales to billions of records without the shuffle penalty.

Eventual was ranked #47 globally on Paraform’s Talent Density Index.

What I liked most about this wasn’t the ranking itself, but how they define it: not by who looks impressive on paper, but by who’s actually developing people the market is fighting for.

A friend put it better than I could:
“Honestly, it’s a testament to the talent you’re recruiting and fostering.”

Feels right.

Grateful to be building alongside this team.

We won 2nd place at Vercel's AI Accelerator Demo Day and I've been told on very short notice that today is Vercel Day on Product Hunt and to do a launch on it. So here it is.

We would love to have your support: https://t.co/T8Er8nrbpb

as you grow older you start realizing that love and care doesn't always come in the form you desire

you look back to your childhood. the nagging, the sliced oranges you didn't ask for, your parents asking about your school day. you didn't realize but that was the only way they knew how to care about us. they grew up in an era where no one thought them how to put feelings into words. they could only show you the only way they knew how

fast forward to this digital age, social media bombards you with 8011 ways of showing love, attachment theory, "if he wanted he would", hyper analyzing text message. and you immediately dismiss them when they miss one single thing you assumed they'd know

they leave you on read, they miss a special day, their tone feels slightly off. and your brain does what brains do with imperfect information. it fills the gaps. small doubt becomes narrative. narrative becomes infection. infection becomes overthinking

the truth is you don't know everything. you don't know they had a brutal day. you don't know they been carrying that immense stress for months. or maybe you knew and you were just selfish because it's easier to make up fake reasons as to why they don't care because it protects you

but protection comes at a cost of weakening the bond. overthinking erodes your ability to receive care and also dismisses their efforts

if you for once stop looking for things that went wrong and start noticing the quiet things you find that they care in their own ways. some include you in their prayers. some drive you around at 2am because they sense you are not okay. some wake up at 6am to deliver you breakfast

social media has really fucked up the way we perceive love. in chasing the loud perfect love, we have started overlooking real love. the sliced oranges kind

Caught up with my ex-student Euan Ong at Anthropic, and I was embarrassed to reveal I haven't read his now legendary essay on CS career advice.

is software headed towards a modern day version of the library of babel?

really liked this analogy from: https://t.co/LIiMIA4VFg

[Euan Lim @euanlimzx]

@kylejeong NO ITS A REAL QN !!! as a community, software engineers need to figure out the most effective new way of acquiring the skills of a PM / staff engs given that the traditional roadmap is slowly being eroded

[Euan Lim @euanlimzx]

as a junior dev i feel like there's this strong tension between:
1. the pressure to deliver more output to stand out among the competition, but this comes at the expense of
2. spending more time to learn a skill, knowing that it'll take you a much longer time

do you want to be more valuable in the short term, or in the long term? or does being more valuable in the short term innately open you up to more opportunities in the long term?

the article clearly favours the "slow is fast, fast is slow" mindset to programming, but there's also a risk that a subset of these skills become antique over time

a simple naive answer would be to just do both to cover all bases, but i'm just wondering if forced to make a choice, what would be in your best interest? perhaps something like a T-shaped approach makes sense, but I also feel thats too cursory of an answer.

Really thought provoking article by @AnthropicAI here:

[Euan Lim @euanlimzx]

@kylejeong thanks for sharing the article!! seems like good software engineers of the future will resemble good PMs / staff engs, which then poses the question - what is the (new) most effective way to get to that stage, given that coding is being taken out of the equation
