archgoon··on The Israeli weapons and spyware falling into the hands of despots
I believe ComputerGuru was thinking of cyber weapons as discussed in the article. There's very little need to think too hard for examples of the US selling conventional weapons to despotic regimes; and you certainly don't need to go back to the Iran Contra to find the US doing so.

In any case ComputerGuru is rightly distinguishing between stolen leaked weapons versus deliberately selling them. He's not saying that that it hasn't happened, merely that he chosen example was trash.

Also the cheerful, well positioned shipmates casually blocking access to various parts of the sub as he walks down the corridors.

> It's pretty sad that "look like you know what you are doing and convince gullible people" is probably the best future career advice I can give to my school-age daughter.

I would like to think that you would want your daughter to get more out of life than just raw cash.

archgoon··on In a Sheep to Shawl competition, you have 5 people, 1 sheep, and 3 hours
There are over a hundred thousand sheep farms in the US alone. That's 117 in 6 countries, what percentage of farms had bad practices and how were the ones that were audited chosen?

Given that this is PETA, I would not assume good faith here.

Finally, the original poster makes a universal claim about the nature of sheep farming, which your above anecdotes do nothing to support.

archgoon··on With new trade deal, Big Tech wants to be above the law
The republican primaries are not rigged. The previous elites of the party didn't want Trump in 2016. Republican voters, however, did.

Americans really love to twist themselves in knots to excuse their own laziness with respect to politics. "Oh look at how dysfunctional the government is, but there's nothing we can do about it."

2016 pretty clearly made it clear that at the end of the day, its the people of the US who hold power in their country.

archgoon··on Prompt injection explained, with video, slides, and a transcript
With a slight modification, this basically applies to just about all security vulns ever :)
archgoon··on The AT protocol is the most obtuse crock of shit
When he was ranting about crypto, I had assumed that Bluesky had done another silly Coin or something. Nope, this is just apparently a dislike of public keys and signing messages, which seems like a great idea for a federated protocol.
archgoon··on Proton’s mass radius is apparently shorter than its charge radius
For a back of the envelope calculation we consider the uncertainty principle

Δx*Δp >= ℏ/2

Δp = Δ(mv) >= ℏ/(2Δx)

m = 9.1 * 10 ^ -31 kg (mass of electron)

x ~= 1 * 10^-15 m (radius of proton)

ℏ = 6.6 * 10 ^ -34 kg m^2 / s (plancks)

Δv >= 31 524 512 m /s

Which is about 1/10 the speed of light. There isn't a true cutoff for "relativistic speeds" but in general, 1/10th counts.

archgoon··on Is Y Combinator worth the money? Brutally honest review of W22 batch experience
Advice does not need to be correct to be valuable. Simply getting a perspective on a problem, and a proposed strategy, can improve your ability to reason about your problem domain. If advice is wrong, and you choose not to follow it, then you know that people will ask about it later and you will be prepared to explain why you thought it was wrong; which is a better situation then saying to potential investors "Gee, never thought about that option."

That is to say that advice, right or wrong, gives you information about the problem space and perspectives on it; which can be valuable if you evaluate said advice critically.

As an example "You should always unit test your code" may not be applicable, but being able to say something like "This code is almost 100% dealing with External systems so a pure unit test would not be the appropriate way to test this code" is a better answer than "What's unit testing?" (Yes, I'm sure someone is going to quibble with this example :) )

Yep, as are most of the other comments.

archgoon··on Amazon starts flagging frequently returned products that you maybe shouldn’t buy
This is true; but this is a cost optimization argument; not a feasibility one, which is all the OP was proposing.
archgoon··on We updated our RSA SSH host key
Once took a security course where the prof accidentally opened his rsa key file while streaming.
archgoon··on A growing number of scientists are convinced the future influences the past

That was Oppenheimer, not Feynman.

I'm not entirely sure what purpose bombarding politicians with ChatGPT emails is if their response is simply to run ChatGPT to create automated replies.
archgoon··on I changed my mind about nuclear waste
The author gave a fairly detailed account of how nuclear waste is processed and its general safety. Which claims do you take issue with?

As it stands, I have learned considerably more from her post.

archgoon··on I’m now a full-time professional open source maintainer
Part of being successful here is tooting one's horn.

In what sense does HN have shadow banning (sort of)?

archgoon··on Amazon Smile Gets a Frown
Google result:

> Effective altruism is a research field and practical community that aims to find the best ways to help others, and put them into practice.

Doesn't sound that bad.

I believe you misread that.

Pdfs are readable by machines. It's also released as tex.

Huh. this account apparently got shadowbanned. Guess it's another good reminder not to post here.

archgoon··on MIT study: Covid-19 vaccines may be less effective for racial minorities
It probably is that simple; not sure why I'm being downvoted for pointing out the obvious.

Ah fuck it; nuking my account. I shouldn't waste time here arguing with people.

archgoon··on MIT study: Covid-19 vaccines may be less effective for racial minorities
Seems like mostly a non issue, even if their model is correct. If you have a 10% chance of the vaccine being ineffective for an individual, then the vaccine is still about 85% effective for that population, which is more than enough to pull the R values well below 1.
archgoon··on AWS Lambda pricing now per ms
Huh... that's the limit of lambda functions, are you doing some sort of work in 15 minute chunks?
archgoon··on Parse, don’t type-check
Clojure, for those unfamiliar with the language, unsurprisingly, does in fact allow for both 'for' and 'while' loops, and are part of the core language library.

https://clojuredocs.org/clojure.core/while

https://clojuredocs.org/clojure.core/for

And here are examples picked from a random repository of these constructs being used in the wild:

https://github.com/ring-clojure/ring/search?q=while

What clojure does do is also provide a number of higher level control constructs, and, by the nature of the syntax of the language, puts them on the same level as 'while' and 'for', which themselves are part of a library, rather than baked into the language itself.

This can, of course, be done in other languages, using fluent interfaces.

https://en.wikipedia.org/wiki/Fluent_interface

But is typically much more awkward and harder to compose. Also, you typically have to wrap expressions in lambdas.

archgoon··on US internet speeds 91% faster in 2020 according to user speed tests
Can you expand on when competition came to Seattle and how? I've been using Condo Internet (now Wave Broadband) for something close to 5-6 years. When was the tipping point in terms of competition?
archgoon··on I should have loved biology
I suspect that there is a transition, that happens after high school for some people, where the world goes from a bewildering set of disjointed arbitrary facts that need to be memorized, into comprehensible system that can be understood and behavior predicted (with sufficient effort).

I also suspect that part of this is that software engineers, realizing that they can now purchase things like lab equipment and bacteria cultures, are now free to fund their own learning in their own idiosyncratic way (much like they learned to program), and not worry about burning money on something that doesn't pan out.

Between this, a new confidence that the world is understandable and... debuggable, and the fact they can finance their own experiments, gives a shift in perspective that wasn't available when they were in high school.

archgoon··on Why I teach vim
Unfortunately, vim macros don't tend to get implemented when other editors implement keybindings.

This is unfortunate, vim macros are fantastic for reformatting text.
