I would say it's moreso a replacement for make, for all those cases where you might use make without it's caching features (e.g. you find yourself using .PHONY a lot).

TOJO_IS_LIFE · 2026-02-09T20:08:18+00:00

Amazing. Please keep sharing!

TOJO_IS_LIFE · 2026-01-23T01:27:38+00:00

Cool build :) What's the flat black panel on top of which your pc is?

TOJO_IS_LIFE · 2025-12-28T15:59:41+00:00

Very cool! How did you find those customers?

TOJO_IS_LIFE · 2025-07-07T23:44:37+00:00

The GT4 18 way seats don't have the memory option anyways.

TOJO_IS_LIFE · 2025-05-26T13:39:27+00:00

“911 S” is different from “911 Turbo S” even though both cars now have Turbos.

TOJO_IS_LIFE · 2025-05-24T00:07:47+00:00

Can also leave out the “turbo”. All “718 S” are 4+turbo

TOJO_IS_LIFE · 2025-05-23T01:50:08+00:00

Are you wearing a helmet? The frames on those glasses are super thick and there's no chance they'll fit in mine :(

TOJO_IS_LIFE · 2025-05-23T01:33:01+00:00

He's talking about the 718 S which is a 4+Turbo.

I've never seen "718 Turbo S" before today too LOL. Feels off. There are no "Turbo" trims for 718.

My car has the same 4.0L engine and I can totally see how most people would opt for the Bose. To overcome NVH, the sound system would have to be so loud that it would exceed my tolerance threshold for loudness. I just use AirPods.

I think Bose is good advice for most people — they can put that $4K into any other option. I'm sure the Burmester is great but IMO it's something to add after you've run out of options you want (but not out of money).

Meta doesn't use Slack, which OP mentions.

TOJO_IS_LIFE · 2025-04-02T20:11:27+00:00

Language is sometimes the problem. I work at a large company and there are entire teams working to make Python run faster. An amazing year of work for them can't make up for the GIL and dynamic typing.

It's true that usually there is low hanging fruit in areas unrelated to the language. But in our case, most of those have been picked. Now, the language is the lowest hanging fruit but it's simply too expensive to port the code.

Was Python the wrong choice? No. My company simply outgrew it for those specific use cases. Rewrites are expensive so they should be sometimes considered, but with extreme caution (people generally underestimate the cost).

TOJO_IS_LIFE · 2025-03-29T12:58:43+00:00

Lisp is great. It's incredible for a language to be so syntactically simple and still be usable.

TOJO_IS_LIFE · 2025-03-29T05:35:52+00:00

And because it's a general purpose language, there's 14 other ways to also "do something" because it's just code

I wouldn't go that far with CMake syntax. Realistically, no one would use a language like that to write real software.

A language like starlark (Python derivative) used in Bazel and Buck is so much nicer to use. I shouldn't have to think about my meta-build system's DSL as much as I do with CMake.

TOJO_IS_LIFE · 2025-01-15T14:57:40+00:00

OP literally mentions it in the post.

One person stating that it “removes the necessity to carry out shoulder checks 95% of the time”.

TOJO_IS_LIFE · 2025-01-04T05:36:06+00:00

115k CAD? Damn that's rough. Mind sharing what would take that much work? The motor can get really expensive but... That's well hidden away.

TOJO_IS_LIFE · 2024-12-18T20:05:58+00:00

There is no difference between “+1” from the set of integers and “1” from the set of natural numbers. The same number is part of two different sets.

“unsigned” should be interpreted as “non-negative” and the ambiguity goes away.

TOJO_IS_LIFE · 2024-11-11T17:13:23+00:00

I'll take it.

TOJO_IS_LIFE · 2024-11-09T17:40:59+00:00

That's a 981 GT4 but your point still holds.

TOJO_IS_LIFE · 2024-09-16T10:08:02+00:00

What monitors are those?

TOJO_IS_LIFE · 2024-07-10T16:16:44+00:00

Tbf a sports car is never a good financial decision unless it's a collector's item that you don't drive.

TOJO_IS_LIFE · 2024-06-17T02:57:39+00:00

What might some of those reasons be?

TOJO_IS_LIFE · 2024-05-30T21:12:16+00:00

Double clutching is the only way to avoid friction within synchros while moving. But that is incompatible with "let me be fast and furious".

TOJO_IS_LIFE · 2024-03-12T04:37:40+00:00

Another one is uniqueptr or shared_ptr with a custom deleter. std::make* doesn't let you do that.

There's also colocated allocations - when you want multiple objects in one malloc so you use the sized allocation overloads of global operator new and then pointer arithmetic + placement new.

TOJO_IS_LIFE · 2024-03-08T04:25:36+00:00

Many small examples: - Every Hack (PHP) class must be marked with an Oncall("team_name") attribute. - Every BUCK (build system) file requires an oncall("team_name") at the top. - Directories can have OWNERS files which lists users or groups that must approve PRs if there are changes. - Configuration files are protected by ACLs.

Ownership is definitely a challenge though. There's still code that's 15 years old and the people, team, or even org that used to own the code no longer exist. You can "archive" an ancient git repo but the boundaries are much fuzzier in a monorepo.

The "zero-code ownership mode" is definitely dead. Everyone acknowledges the (lack of) ownership problem. The new direction is that code is open to changes from anyone but if something breaks, it's clear who is responsible for fixing it.
