drewrv··on U.S. Treasury sanctions virtual currency mixer Tornado Cash
So far, the only thing "cryptocurrency" has revealed is that finance regulations are mostly useful and good.
drewrv··on Phrases in computing that might need retiring
Tech debt is one of the few metaphors I love because it’s so accurate. What a lot of engineers struggle with is that manageable levels of debt is fine for a business and in fact superior to being cash constrained.

Some forms of debt are a headache if the business goes south but tech debt can be ignored if the software project goes nowhere. So the “terms” are good.

Rather than complaining about tech debt, one should communicate the advantages of paying it down or the risks of taking on too much. But the metaphor works and simply referring to “debt” will not dissuade people because a bit of debt is fine.

drewrv··on Former Republicans and Democrats to form new third U.S. political party
How does a party of such people organize? What policy positions could they hold on abortion, lgbtq rights, and gun rights that will lead to wide appeal?
drewrv··on The Case for C# and .NET
It's a pain, but there are some optimizations to shrink the large download size.

This person was able to get it from 14.4MB to 4.4MB: https://www.michielpost.nl/posts/reducing-blazor-webassembly...

Whether that's acceptable is up for debate but it is in line with most SPAs/websites these days.

drewrv··on Ask HN: Who is using the .NET stack for their startup (2022)?
I haven't launched a startup on .NET recently, but I've been looking into modern .NET and I'm pretty impressed. I'll probably use it for my next side-project.

I think Blazor in particular has a lot of potential. I've grown disillusioned with front-end development over the past 5 years so it's worth trying something new and experimental. But I'm not sure I'd bet my career on it or ship it widely yet.

drewrv··on US Supreme Court says EPA can’t regulate carbon pollution under Clean Air Act
Couldn't congress "get off its rear and do its job" by forbidding the FDA from regulating housing? Requiring every regulatory action to require an affirmative from congress is absurd.

Besides that, congress controls the budget for these agencies. Simply by funding the EPA and the FDA, it demonstrates a level of support for their actions.

drewrv··on Supreme Court limits EPA’s power to cut emissions
This term alone the "conservative majority opinions" have been downright contradictory on "relevant legal issues". Women now have a right to defend their life with a gun but cannot defend their life with healthcare.

It's clear that they are simply using "originalism" to cherry pick what falls in line with their personal opinions.

drewrv··on What Caused the 2020 Homicide Spike?
Crime data is messy and can take decades of debate without ever coming to any conclusions. Beyond the abortion argument, I’ve heard convincing claims that the cause of a decline in crime was due to phasing out leaded gasoline.

For 2020, I blame Tiger King for glamorizing a life of crime. I’m prepared to put together some infographics about it and the theory will be as convincing as any other.

drewrv··on The SQLite Code of Ethics
Not an open source project, but I’ve seen a Code of Conduct save a local user group when drama erupted between a founding organizer and a regular member.

Having a written agreement and guidelines to mediate conflicts is vital once a community gets to a certain size. Humans have been doing this since Hammurabi.

drewrv··on If it isn't going to work, just shut it down
The stuff he’s criticized for doesn’t “challenge” any narrative. It’s all self inflicted like lying about FSD or calling someone a “pedo”.

And what do you consider “the establishment” to be exactly?

drewrv··on Reddit bans ‘SFW’ deepfake community
I don't know of any social media site that has been able to "consistently" enforce moderation at scale. When you have millions of humans they will find every edge case and workaround to any specific legalese you come up with.

Courts struggle with it too: https://www.youtube.com/watch?v=qhWCk2f2alI

Smaller sites like HN do better compared to twitter or reddit, because it's easier. But ultimately it all depends on what kind of communities the company wants to nurture.

While it would be nice if social media companies actually said the truth about moderation rather than pretending there's some content neutral principals they're applying, I also think a lot of people would be better off if they accept that social media is what it is, and move on if they don't like it.

drewrv··on Amazon investors nuke ethics overhaul and say yes to $212M CEO pay
I feel like you’re using the word “fair” in an econ 101 sense, not in the way most people use it.

“The market reached equilibrium” with child labor and indentured servitude. Most people consider child labor unfair, so law/culture/customs changed how the market operates.

Even within the narrow definition of “fairness” in economics you still have externalities. This can become really tricky and require ethical considerations beyond a “pure math” problem.

drewrv··on In defense of coding interviews
It’s unrealistic to expect this level of optimization in a generalist whiteboard session. For a specialist, maybe. I’m not specialized in this area.

For an array of 5-10 items the performance hit of foreach is worth it for readability. Maybe an interesting discussion could occur about when to sacrifice readability for performance but you won’t get that by grilling people about minutiae.

drewrv··on In defense of coding interviews
It is nice to hear a defense of this style since there’s often so much complaining about it, and the tips to mitigate the downsides are useful.

Personally I don’t mind a whiteboard session or two during a loop but what’s wild to me is how, especially at big companies, you’re expected to do four or five of these to get an offer.

How often do these companies decide “well they understand when to use DFS and they can merge-sort a linked-list and they knew to use dynamic programming but we can’t hire them because they couldn’t remember how to implement a heap”?

drewrv··on Amazon investors nuke ethics overhaul and say yes to $212M CEO pay
> Fair, by definition, is when the market reaches equilibrium.

This is absurd. "The market" is amoral: it's just a collection of human behaviors that are shaped by laws, culture, and customs. All of those can change, the law can change quite easily.

drewrv··on Netflix’s bad habits have caught up with it
I don't know what state you're in, but many states have senior citizen exemptions, or low income exemptions.
drewrv··on Show HN: A site that puts in a referral for you for your dream job
I often see people on blind asking for and offering referrals to people who are basically strangers. It makes sense to turn that into a product, so kudos.

That being said, it's always made me feel weird in a way I struggle to articulate. It seems cool to offer an opportunity to someone who needs it, and referral bonuses are nice for workers.

But it does seem to go against the spirit of referral bonuses.

I suppose if companies were really upset by people hacking their referral system they could simply fix their online application process so that it doesn't go nowhere.

Looked at a different way, the companies are essentially paying bonuses to their engineers to do resume screening. It seems like if that's what they really wanted they could ask people to do it as part of their job though.

drewrv··on Astronomers reveal first image of the black hole at the heart of our galaxy
Reading between the lines of this page: https://en.wikipedia.org/wiki/Timeline_of_the_far_future

The sun itself may get ejected into intergalactic space when the Milky Way merges with Andromeda. (< 5 billion years from now)

Earth will probably be totally engulfed by the sun when it goes red giant, or it might not in which case presumably it will continue orbiting. (7.59 billion years from now)

By 100 billion–1 trillion years from now all galaxies in the local group are expected to have merged, so there will probably be other opportunities for the sun to get yeeted into intergalactic space.

By 10–100 quintillion it's expected that 90-99% of all stellar remnants will be ejected.

Finally, at 10^30 (1 nonillion) years from now, we get this gem: Estimated time until most or all of the remaining 1–10% of stellar remnants not ejected from galaxies fall into their galaxies' central supermassive black holes. By this point, with binary stars having fallen into each other, and planets into their stars, via emission of gravitational radiation, only solitary objects (stellar remnants, brown dwarfs, ejected planetary-mass objects, black holes) will remain in the universe.

One thing to keep in mind though is that by the time our sun gets sucked into a black hole, the galaxy will have merged so it may very well be a different black hole, or this paticular black hole may have merged with multiple other ones.

drewrv··on Astronomers reveal first image of the black hole at the heart of our galaxy
I've heard it said as "The universe is under no obligation to make sense to us". It's possible that the events where the two theories diverge will always be out of reach for us to observe.
drewrv··on Things to know about raising debt for startups
There are companies that offer loans like this but the rates aren’t great. Also mortgage lenders don’t like it if your down payment is debt.

I believe wealthy people (so some founders) do this on better terms because they have a better negotiating position.

drewrv··on Google Docs will “warn you away from inappropriate words”
Next thing you know there will be actual laws that ban what can be said in schools, books being banned, and laws that allow drivers to run over protesters.

Fortunately the people who are vigilant about Twitter moderation policies and word processor features are acting in good faith and will be outraged by actual government attempts to stifle speech.

drewrv··on Ask HN: How to find users if the problem you're working on is widespread?
A couple of ideas:

- Figure out how to target the people who are immediately looking for your service or might be. For the home example, people going to open houses, people searching mortgage rates, renters who just had a kid or got married, Employees of a startup that just IPO'd or was acquired.

- Try to get referrals from happy past customers. I've used home buying services and also recruiting services that will just straight up mail me a check for thousands of dollars if I was a customer, and sent them a friends referral.

drewrv··on Elon has decided not to join our board
I think that him taking over Twitter would be terrible for everyone involved.

The general public would be better off if Tesla and/or SpaceX actually accomplished their stated goals. What they’ve done is great but they’re not done and need leadership.

Twitter would be way worse off if he turned it into Gab or 4chan with an edit button. Both their product and their financials.

Musk himself is turning into a cringy Twitter troll. If a friend of mine were acting like that I’d tell them to put the phone down and go for a walk. The less he thinks about Twitter the better.

drewrv··on Fossil of dinosaur killed in asteroid strike found, scientists claim
Thanks for posting this. I didn’t know about it and it’s lead me down quite the Wikipedia rabbit hole.
drewrv··on Elon Musk to join Twitter’s board of directors
Who has been banned from Twitter for a joke that offended "only the wokest"? Dave Chapelle still has a twitter account. As does Louis CK.
drewrv··on Block a tweet, its author, and every single person who liked it
There's a number of people who pretty much have to use Twitter for their job. Writers, pundits, journalists, etc.
drewrv··on Basic Quantum Algorithms
For those who are interested, this lecture was sent to me as an overview of quantum computation for people like me: people who know how to code and know some basic linear algebra.

It goes deeper than the pop-sci articles about "doing all combinations at once" but remains accessible and by the end you understand entanglement and can read some Q# code.

drewrv··on Solid.js feels like what I always wanted React to be
Knockout.js was/is wonderful, I'm not sure why it never took off the way angular or react did. I do appreciate jsx though so I'll be looking into Solid.
drewrv··on Why are semi trucks in the US and Europe so different? (2018)
I don't know a good article, but for some reason I was curious at one point and discovered the marketing pages for various big rigs. Marketing materials presumably showcase more flashy features and higher trim levels.

Also the /r/Truckers/ subreddit has users post their setup sometimes. But usually those are either "look what I was able to cook" or "check out my gaming setup".

drewrv··on An open call to restore normalcy for U.S. children
I feel like it's worth pointing out this study is from Johns Hopkins Institute for Applied Economics, Global Health and the Study of Business Enterprise.

The authors are all economists, none have a background in epidemiology or medicine.
