@AdrianneCurry Get this : uasure.com

I just got diagnosed loosely with gout. Awaiting my bloodwork. Most people get gout from fun stuff like booze and stuff...mine? Asparagus. Spinach. Avocado. Beef organs. Sigh

@BarbellFi Because inflation can eat your lunch that way. If you bought $1m in 30 year bonds in 1965 by 1995 your returned principle was worth ~$212k in 1965 dollars. You lost almost 80% of your principle for a 4-5% yield.

30 year treasury bonds yield 5% now $1 million invested is $4,200/month Completely risk free & state tax free That’s $50k/year paid out for 30 years Then get the million back after 30 years Why aren’t more people doing this? 🤔

@asymmetricinfo I actually tested this in grad school. What we found was that dominant cursive writers wrote faster in cursive, dominant printers wrote faster printing, and there was no statistically significant speed difference between dominant cursive or print writers.

Yes, of course, but also, the reason cursive exists is that it's easier and faster to write so no one had to be forced after they learned it.

@stylishdawg With what time? Seriously... if you are really senior who has the time to invent trouble, there's so much naturally arising trouble...

yeah i think this is very true. minor details def matter sometimes. but i think its a combination of: 1. cargo cult, like you said 2. in order to reach senior, most levelling guides will have you do more non-technical process type work, which leads to a lot of seniors that feel the need to shoehorn that stuff in when it doesn’t matter

> dumb obsession over minor details > check level > senior engineer every time

@Chaos2Cured @yacineMTB Mostly I have just made a *huge* number of errors at high rates... and learned from at least some of them, sometimes after repeating the mistake for the second or third time 😀

@edwarnicke @yacineMTB Following you. You seem like a solid dude. Have a great day. •

one of the things i've learned about incredibly competent people is that they are incredibly competent at everything. it's either nothing or all. like, if someone is really good at one thing, they tend to be good at everything life is just unfair like that

@Chaos2Cured @yacineMTB People who are incredibly competent at only one thing can easily miss the work involved on digging in on other things. Once you hit at least two, they recognize the work needed, and dig in properly.

@Chaos2Cured @yacineMTB My experience is likely a slight nuance on your observation: people who are incredibly competent are at least two things are incredibly competent at anything they turn their mind to. The 'at least two' is crucial.

@ibuildthecloud Sort of like mutexes in Golang. Are they sometimes the right tool. Sure. But infrequently enough that you should be suspicious whenever you see them in a PR.

I feel like if you memoize a component that should be a strong indicator that you might be doing something wrong. I don't want to say it's an anti-pattern, because it has it's place, but yeah, it shouldn't be the norm.

@DominikTornow Memcpy is the future.

TCP is an outdated abstraction Stop designing around connections

@ibuildthecloud MAY we have your feelings on SHALL?

My natural objection to authority gets triggered by specs using MUST and SHOULD. I'm like, "you can't tell me what to do."

@mccricardo More critically, as engineers, it’s our duty to ask ourselves whether a pattern applies to a problem at all. Much mischief has been wrought by engineers with a limited tool box of patterns beating on a problem with one of them instead of seeking out a more appropriate tool.

Pattern: a particular way in which something is done, is organized, or happens. As engineers, it's part of our job to understand several patterns and how to adapt them to our context. It's not to apply them verbatim.

@ibuildthecloud Wait... what do you have against FactoryBuilderAdapterDelegateImpls ...

This book destroyed a generation of programmers. I was one of them. Took a very long time to unlearn this crap.

@CTOAdvisor I do am concerned about how we train seniors without the experience of being junior. There's a lot of learning that goes into being able to get good results out of GenAI (and correct its mistakes). If we just replace the juniors with AI, where do the next seniors come from?

I'm fairly confident that I could return to a senior engineering role armed with GenAI. It's a powerful force multiplier in the right hands. Ed's earlier point is that senior IC will find it very similar in effort to managing juniors.

@CTOAdvisor If someone is really *up* to performing at a more senior engineer level but is in a junior role, GenAI code gen can look like its making them more senior... but its just enabling them to show they are more senior. 2/

@CTOAdvisor GenAI for code tends to be useful in the hands of developers senior enough on a topic to 'supervise' it properly. Seniors will often spend a lot of their time 'supervising' more junior engineers who write a lot of the code. GenAI can replace those juniors. 1/

The new DORA report says GenAI improves developer “flow” and “productivity” by a few percentage points. But something about that isn’t passing my sniff test. I’m on Day 11 of my Zero to Builder journey. I’m talking to senior engineers every week. And here’s what I’m seeing firsthand: Experienced developers aren’t just working faster. They’re working differently. •AI assistants are writing thousands of unit tests in minutes. •Devs are spending less time on boilerplate—and more time solving strategic challenges. •An AWS Principal Engineer told me how AI now frees him up to focus on system-wide innovation, not syntax. GenAI isn’t just speeding up developers—it’s making them more senior. The DORA report hints at this shift, but it doesn’t fully capture it. If you’re only measuring how much code GenAI helps produce, you’re missing the bigger story: AI is changing what we build, how we think, and who gets to be a builder. #ZeroToBuilder

@CTOAdvisor Complexity can’t destroy it, it can only be moved around.

I’ve seen this play out too many times: A messy, bureaucratic solution gets replaced by a “simple” one. But when you scale it… the complexity reappears. Turns out, the old system wasn’t dumb — it was just dealing with reality. Scale breaks everything.

@ChrisShort It only took me decades to realize I'm the same way :)

I am always surprised when I have an issue I can't seem to resolve, I step away from it, let some time pass, sleep on it, and the next morning I get it working right. I've been this way my whole life!!! It always surprises me.

@IterIntellectus Not to be difficult... but do you have a cite on that lives saved number? Because it feels low to me..

haber-bosch process. 3-4 billion lives and counting

@themgmtconsult @rebelEducator Day prison

@rebelEducator School is babysitting.

Wait, so let me get this straight: Kids are *legally required* spend 7 hours in school, 180 days a year, for 13 years ... ... and yet 54% of American adults can't even read at a 6th grade level? Please make this make sense.
