So don’t follow me and I won’t be on your timeline?

This is not a ChatGPT wrapper and no I’m not sick of hearing about innovative companies solving interesting challenges. Like how to serve models at scale inside a company w thousands of devs all using a bunch of different models…

At those advocating for 996 at AI startups it apparently is

Offices in SF; whole team in-office. They are a small team that only pulls silly hours when they want to and makes sense (small team, everyone has equity ofc.)

But weekend work is not the norm; staying late is not expected; ppl take summer vacations, have families.

They work hard sustainably.

Went to the offices of a “cracked” AI company that is killing it: massive AI companies and Big Tech are customers. Building innovative infra. Have a bold vision.

They work really hard. Yet Friday 5:30pm the office was empty - everyone went home to family.

Success != 996

Some coincidence: got a notification and the name looked oddly familiar: it’s the author of the book I’m reading on my flight! And I have WiFi.

I’m halfway though Code Health Guardian by Artie Shevchenko. Lots on how to design software - tactics that feel even more important when working with AI.

It's here: learning.oreilly.com/library/view...

It's really full cricle: I pitched this exact book, with the exact structure to O'Reilly as my first choice publisher.

At the time, they decided to not go with it, and wished me best of luck. But finally it's available with them as well!

The Software Engineer's Guidebook is finally available on the O'Reilly platform! So if you have an O'Reilly subscription, you can read it.

This was a very frequently requested platform: glad that we could make it happen with the O'Reilly team!

thank you! Yes I have a console and prefer those games. I have a kid who is more about the kinds of games that consoles don't have (e.g. decorate a room; dress up a character etc) and hence struggling with these iPad ones that are like that, but predatory in weird ways (a friggin' room decor game!!)

... because your day has been a series of nonstop interactions, so you had to figure out how to do deep work in small chunks that could have been interrupted

I wonder if devs like this will embrace AI agents far faster (and maybe better?) vs devs used to only working "in flow"
gergely.pragmaticengineer.com
I get a feeling that working with multiple AI agents is something that comes VERY natural to most senior+ engineers or tech lead who worked at a large company

You already got used to overseeing parallel work (the goto code reviewer!) + making progress with small chunks of work

Look you don’t know me, I don’t know you. I won’t tell you how to parent, please can you do the same?

I trust you are a great parent and do the best for your kids. Bye!

Again, I’m pretty sure it’s because of loading ads in the background

Incredible that it’s not possible to pay for a game with no ads, no in-app predatory stuff, save for few exceptions (eg Apple Arcade)

2. Game that has no online functionality and one I paid to remove ads won’t start without an internet connection / in flight mode!

3. In-app predatory payments with dark patterns everywhere
gergely.pragmaticengineer.com
As a parent with a kid who’s starting to play games on the iPad, I’m so pissed at the predatory state of kid’s games.

1. I pay $7 to remove all ads from this game. Yet catch my kid watching ads - even after paying they are offered to watch for in-game rewards. WTH

2. (cont’d)

Three years later, this prediction happened as expected.

Bootcamps are mostly dead and have been dying since 2022: because of the job market.

New grads from college / uni can barely get jobs. Boorcampers even less so: no demand

For an AI startup today, what language would be the best choice: Python, TypeScript, Go or Rust?

Armin Ronacher is a great person to answer: a longtime open source contributor, creator of Flask (a Python fullstack framework), and he's building his AI startup. Spoiler: he's not using Python for it.

The Linear Euro Tour tonight in Amsterdam. The dev asking a question from the Linear Eng team travelled from Germany to be here tonight 😲

Great event

thank you - I'm going to do this. This is getting under my skin now

Might be the sign for me to block ads. I've been lenient about this, but those without this issue all tell me they are agressively blocking all ads.

Time to bite the bullet. Thanks!

Wonder if there's a correlation here w/ ads & tracking, which has absolutely exploded in recent years. I don't observe the same jerkyness w/ Chrome, but I also use NextDNS to block a lot of traffic.

I don't think it's just that, but maybe contributes!

All I do is open a few tabs in Chrome here and there - and an hour later my computer is jerky and lags.

I check, and every single time it's Chrome taking up well over 16GB.

In 2025 I still don't understand how memory can sprawl so much in browsers, and why

*kills Chrome*

and yet, native mobile engineering was not all that understood by leadership

also, Uber had (and has) 5x or more backend engineers than mobile engineers.
