cvwright··on How I estimate work
I think Claude’s estimates are biased towards huge enterprise projects.

I asked it to estimate a timeline for a feature in my hobby project and it confidently replied, “4.5 weeks to code completion”.

Less than 4 hours later, the feature was done. I asked it to compare this against its initial estimate and it replied, “Right on schedule!”

I have completely given up on using it to estimate anything that actually matters.

cvwright··on Statement by Denmark, Finland, France, Germany, the Netherlands,Norway,Sweden,UK
By that logic, the European members who didn’t meet their defense spending obligations for years and years have already left NATO too.
cvwright··on A faster heart for F-Droid
Unfortunately you can’t even get the RAM for $400 anymore.
cvwright··on Rob Pike goes nuclear over GenAI
But mining all the tracking data in order to show profitable targeted ads is extremely intensive. That’s what kicked off the era of “big data” 15-20 years ago.
cvwright··on Jingle Bells (Batman Smells): An incomplete festive folk-rhyme taxonomy
The redneck version that I heard as a kid was way worse than that. Things I won’t repeat…
cvwright··on Why We Abandoned Matrix (2024)
Don’t blame the user - blame Matrix for designing the system like this.

> They have to be stored somewhere. You want private keys on the public server?

Yes. Encrypted. The feature is called “dehydrated devices” and the Matrix team has been working on it for quite a while now.

cvwright··on Nano Banana can be prompt engineered for nuanced AI image generation
Well but then they spent 100 years telling us that the toddler stuff was the good stuff. Just as long as it was created by a “real artist”.
cvwright··on Metabolic and cellular differences between sedentary and active individuals
Usually in this context it means “the max effort that you can sustain for 2 minutes”.

Same thing goes for a 20-minute max effort or even an hour etc.

cvwright··on Advice for new principal tech ICs (i.e., notes to myself)
The contradictions are difficult but wisdom has always been like that. See for example the book of Proverbs, it’s full of contradictory advice.

“Do not answer a fool according to his folly, lest you also be like him.”

Versus

“Answer a fool according to his folly, lest he be wise in his own eyes.”

The skill is to understand the truth of both statements, and to discern when to apply each one.

cvwright··on Rand Paul: FCC chair had "no business" intervening in ABC/Kimmel controversy
A big part of modern discourse is people tactically pretending to not know stuff
cvwright··on Rand Paul: FCC chair had "no business" intervening in ABC/Kimmel controversy
So you’re telling me that, in the past 10 years, this was the only speech on network TV that the Trump crowd didn’t like?

Kimmel got caught spreading blatant falsehood about who the shooter was. That has always been against the rules for public airwaves.

cvwright··on Oxford loses top 3 university ranking in the UK
How are the grades of a student in a prestigious position at Oxford not relevant to the academic reputation of Oxford?
cvwright··on Oxford loses top 3 university ranking in the UK
And it’s being reported that the new president of the Oxford Union only had A B B.
cvwright··on Pontevedra, Spain declares its entire urban area a "reduced traffic zone"
Safety is the much bigger challenge for public transit in the US right now. Since the pandemic, most cities have really eased off of any enforcement of rules or laws in public spaces.

Driving in rush hour traffic sucks, but it beats getting randomly stabbed in the neck by some psycho who didn’t even pay his fare.

cvwright··on White House in Talks with Intel for 10% U.S. Government Stake
It’s the end of the postwar consensus and the return of the “strong gods”.

Before: hands-off economic liberalism.

Now: doing what seems best for ones own nation state.

See “Return of the Strong Gods” by RR Reno for an interesting explanation of lots of puzzling behavior from major political parties.

cvwright··on NIST Finalizes 'Lightweight Cryptography' Standard to Protect Small Devices
Good news. We’ve waited so long that AES is pretty damn lightweight now too.
cvwright··on Claude says “You're absolutely right!” about everything
This illustrates the dangers of training on Reddit.
cvwright··on H-1B Visa Changes Approved by White House
Americans can do software development as well
cvwright··on Exile Economics: If Globalisation Fails
Are you trying to imply something racist? Just come out and say it.
cvwright··on M5 MacBook Pro No Longer Coming in 2025
I think Apple has historically used the college student market to clear out their remaining stock of last year’s MacBooks. Otherwise why release the new models just after classes have started?
cvwright··on Food, housing, & health care costs are a source of major stress for many people
The costs also used to be a lot lower - at least for most people who just pay the premium and don’t need much care. Now it’s not uncommon for a family’s health insurance to cost more than their housing.

The people who are mad are those who are paying more and not experiencing the benefits.

cvwright··on Tour de France confronts a new threat: Are cyclists using tiny motors?
Sure it was great to see Wout win again - in Paris no less! And it does kind of validate the TVL strategy of “wear Pogi out with 3 super hard weeks of racing.”

Unfortunately for them it just wasn’t enough to make the difference in the GC.

cvwright··on Tour de France confronts a new threat: Are cyclists using tiny motors?
But like Jorgenson said this year, there’s no tactics that can beat Pogi going up a steep hill at 7w/kg. At some point it all comes down to power to weight.
cvwright··on UK backing down on Apple encryption backdoor after pressure from US
Funny how nobody in this thread has mentioned which party is running the UK right now…
cvwright··on MonsterUI: Python library for building front end UIs quickly in FastHTML apps
It kinda looks like SwiftUI
cvwright··on AI makes the humanities more important, but also weirder
No but people do pay universities for (among other things) a meaningful credential that testifies to their knowledge and abilities.

If taking away phones is what’s required to make that credential meaningful again, then the universities must do it.

I think of it like a personal trainer. Do you pay them to make you sweaty and sore? Not really, but sweat and soreness are consequences of doing what it takes to build muscle/endurance/etc.

cvwright··on There Is No Diffie-Hellman but Elliptic Curve Diffie-Hellman
There are no proofs of the hardness of DDH or RSA etc. That’s why they’re called assumptions.

OTOH if you want to win a Turing Award…

cvwright··on Social media platforms: what's wrong, and what's next
Having tried (and failed) to build a more privacy friendly social network, I can confidently tell you that the big players in this space do the shady things they do solely because users reward them for doing so.

Trying to grow a new product is super hard. Trying to move into an established market is even harder. Trying to do that while also foregoing all the dark patterns is … well I won’t say it’s impossible but ugh it would take a huge head start in terms of name recognition, funding, or something else truly extraordinary.

cvwright··on Why does the U.S. always run a trade deficit?
Problem is that the USD factories don’t provide enough jobs for the US population
cvwright··on “There are people who can see and others who cannot even look”
The pinkie and ring finger share a tendon - this is why they are weaker than the other fingers.

Or, at least that’s how it was explained to me as a kid learning to play the double bass. The standard technique is to use those two fingers together to press the string on the upper part of the fingerboard where the most strength is required.
