Totally. Stopping at a specific time is a good rule of thumb, but you can obviously compensate for one half life by just consuming twice as much at the start.

And the surprising thing too for me: how low the threshold is where it can impact your sleep.

Neat idea. Who is the audience? How often do you think a piece of evidence comes across, significant and noteworthy enough, for the average person? Is that happening daily or close to it?

I've been struggling with poor sleep for months. The 3am wake ups (can't fall back asleep) are really bad.

I figured it couldn't be coffee because I fall asleep easily. But it turns out that lingering caffeine can let you fall asleep at bedtime and then come back to haunt you later when you move into lighter sleep.

I've been in denial about my caffeine consumption because I've gotten away with it until now.

I vibe coded a little caffeine metabolism tool to face reality. I wanted something with a simple half-life formula and drag and drop using common beverages.

What becomes clear very quickly is: my caffeine consumption needs to be way lower and earlier to fix my sleep issues.

Government jobs. But my experience tells me that getting away with doing nothing is very corrosive to the soul and will be regretted later.

You could look at 16% as roughly equivalent to a dice roll (1 in 6) or, you know, the odds you lose a round of Russian roulette. That's my charitable interpretation at least. Otherwise it does sound silly.

There's a difference of $24 but I have $1200 in cash reserves. And I make up the difference later. Oh no! Guess I have to lay off 10% of my employees now.

I can see why it would affect startups not making a profit but why would it dramatically affect FAANG (e.g. some of the most profitable companies in the world that have been running for decades)? The article contributes all these large layoffs in FAANG, in part, to this tax rule.

There were smartphones before the iPhone. One could also describe the difference as "just a touchscreen".

Fair enough, but I don't think you realize how the original comment comes off. There's a lot of wiggle room in the terms "interested", "engineering", and "unremarkable", but the way I take it is: if one hasn't become a legend in their field by age 40, not only do they not deserve a job, they don't deserve to be here (since they're clearly not interested in engineering).

You're right on many of these points and I probably take it personally because I'm coming up on 20 years and am unremarkable. You never know what people went through to get where they are.

I went to a cheap state school, didn't major in CS despite wanting to desperately because my family convinced me it was a bad move, graduated into the GFC, got pigeonholed into QA for a while, spent years getting my masters in CS, wasted energy on side projects for many years, cared for sick family members for many years, struggled with major impostor syndrome and insecurity.

I've done things I'm proud of and I made it to FAANG after all that, but am unremarkable. It's kind of offensive to then hear that I'm not interested in engineering because I'm not a Distinguished Engineer or whatever.

> If you have spent 20 years as a software engineer amassing wealth (3 houses) and not making significant contributions to your peers or the field, everyone knows where your priorities are. It's okay that you aren't that interested in engineering.

Lots of unfounded assumptions and snobbery in this.

> The easiest way to do this is to deliver things that they already know about, such as projects that they’ve asked you to do

I've struggled with this recently. I feel like advancement requires getting credit for the idea itself, otherwise you're just implementing other people's designs. But ideating (will actually good ideas) is pretty tough.

I'm often surprised when someone will paste a screenshot of a tweet with the name blurred (presumably to protect them from harassment). The contents of the tweet are easily searchable...

My experience working at one of the companies that gets accused of this a lot is that many colleagues wish we were as evil as claimed because it would be so much easier do their jobs that way than struggling through the reality of it which is endless red tape over the tiniest issues that have even the slightest proximity to privacy. So I've been a bit skeptical too.

Most of the post is disputing the point you're making. Did you read it?

What people experienced during a trivial, 1 hour study doesn't really compare to regret over decades of someones life.

Did he?? He expanded a bullet list of the different owners to fit a 12 minute video, started and ended the video with an ad, literally said he "didn't have too much to say about Golden Gate Capital", and shares the insight that "Red lobster just needs to get to a point financially where they can be themselves..." OK.

I have to point out that Hyperrogue is far from a tech demo. Though the controls are simple, there's some 60 lands each with fascinating rules and emergent complexities. https://www.roguetemple.com/z/hyper/gallery.php
