I quickly improved my PRs and sped up code reviewing by doing following when I create PRs

- make a diagram if is possible

- make a summary of changes like why this file changed and decision behind this

- make a note about backward compatibility

- anticipate which questions can be asked and answer them upfront

Instead of running each small write query as the event occurs (a vote), collect them in memory and at some time interval (1m, 5m, or whatever your UX will tolerate) write them to the DB in batch with one (or a few) writes.

Apple also doesn't allow new dating apps, with some exceptions (unique, high quality experience, which seems like a judgement call you would have a hard time arguing with App Review):

4.3 Spam Don’t create multiple Bundle IDs of the same app. If your app has different versions for specific locations, sports teams, universities, etc., consider submitting a single app and provide the variations using in-app purchase. Also avoid piling on to a category that is already saturated; the App Store has enough fart, burp, flashlight, fortune telling, dating, drinking games, and Kama Sutra apps, etc. already. We will reject these apps unless they provide a unique, high-quality experience. Spamming the store may lead to your removal from the Apple Developer Program.

I think they use the SIM card country ID and also the ad audience categories to suggest content.

For example swapping the SIM card with a fresh installation of TikTok shows different "local" videos. Even if the public IP address is unchanged like when using WiFi instead of Data.

I've also think they use ad categories to suggest videos. Using a fresh TikTok installation and then spending some time navigating a subreddit of a topic, would likely show videos of that topic the next time you open TikTok.

I'm 33, Ive got a fairly high IQ, make $340k in a STEM field and enough to retire tomorrow, I'm not unattractive, and put a huge amount of effort over many years into online dating. I've pretty much given up on dating. I have a total inability to find anyone I'm interested in that is interested in me.

When I was younger and I wanted to go to bars and get drunk and be an idiot I had plenty of attractive sexual partners.

So I don't buy this at all. The guys I know who have an easy time dating are 1 or 2 points more attractive, make minimum wage as yoga teachers or selling crystals or dumb stuff like that, and tell Women painfully stupid stuff they want to hear about their quantum vibrations matching and other new age nonsense.

So I can say this narrative empirically doesn't feel true for me.

There was a Category 5 Typhoon in in the Philippines where I am last week. The power was out and there was no electricity, refrigeration, or internet for a week. One of the transformers in my neibourhood blew out and got destroyed, and at 6pm on Christmas Eve they replaced it and we finally had power! I'm a software developer with a wife and two kids and we have a lot to be thankful for. We survided COVID-19 and a Category 5 hurricane.

I'm sorry; that's bad. Can you email me with details so that we can investigate what happened? (patrick@stripe.com; others welcome to do so too.)

More than 10,000 people have interviewed at Stripe so far this year, so "several sigma bad" still happens to an unfortunate number of people. That said, we want those who interact with Stripe to come away having been treated professionally and respectfully, and our recruiting team cares about fixing our process failures. On behalf of Stripe, I apologize.
