sc68cal··on Trump's global tariffs struck down by US Supreme Court
That's a great question. I would also love to know that answer. I agree with you that they're not going to share the refund if the importer was the middleman in the supply chain, and same thing if the importer was also the seller.
sc68cal··on Trump's global tariffs struck down by US Supreme Court
The importer pays the tax and passes it on as higher prices to the consumer. So the importers are the one that had the tax collected from them and would be getting the refund.

The importer CAN be the seller, but other times the importer is a middleman in the supply chain.

Jobs are the only way that you survive in this society (food, shelter). Look how we treat unhoused people without jobs. AI is taking jobs away and that is putting people's survival at risk.
sc68cal··on An Update on Heroku
It's such a shame, because they had one of the best services out there. Being able to push via Git and end up with a running deployment was a killer feature. It may not have been the first (Elastic Beanstalk was way older but when it first came out it was Java only iirc, ick) but it was incredibly popular.

Seeing them now chasing AI as a "me too" after being acquired by Salesforce just shows that huge companies will acquire something then sit on it for years and let it rot.

sc68cal··on No More Hidden Changes: How MySQL 9.6 Transforms Foreign Key Management
I think it's a good idea, as a decades long user of InnoDB. I hope that the work can be shared with other forks of MySQL
sc68cal··on Unconventional PostgreSQL Optimizations
Great article, shows a lot of interesting PostgreSQL features. I have used PostgreSQL and MySQL for decades, and this article showed me that I have barely scratched the surface of what is possible.

You completely missed the point of that quote. The point of the quote is to highlight the fact that automated systems are amoral, meaning that they do not know good or evil and cannot make judgements that require knowing what good and evil mean.

sc68cal··on Economics of Orbital vs. Terrestrial Data Centers
When Starcloud put together that whitepaper the first thing I looked at was the launch costs[1]. It references a $5M cost to launch, which right away made absolutely no sense to me. Just a cursory search shows launch costs are around $50M per launch, if not more.

It's great that this site drills down even further to demonstrate that there is absolutely no point at which the launch costs ever make this economical or viable, so I really don't understand what people are doing.

Especially because this site was harping for years about the cost of launches and putting things in to orbit, the whole reason why SpaceX got started and has grown as it has. As soon as that became an inconvenient number, we now just make things up (Just pretend that launch costs are 10% of what they actually are to get people to invest?).

sc68cal··on Golang's big miss on memory arenas
This does make me appreciate some of the decisions that Zig has made, about passing allocators explicitly and also encouraging the use of the ArenaAllocator for most programs.

Since Zig built up the standard library where you always pass an allocator, they avoided the problem that the article mentions, about trying to retrofit Go's standard library to work with an arena allocator.

Although, that's not the case for IO in Zig. The most recent work has actually been reworking the standard library to be where you explicitly pass IO like you pass an allocator.

But it's still a young language so it's still possible to rework it.

I really do enjoy using the arena allocator. It makes things really easy, if your program follows a cyclical pattern where you allocate a bunch of memory and then when you're done just free the entire arena

Their margins are negative and every increase in usage results in more cost. They have a whole leaderboard of people who pay $20 a month and then use $60,000 of compute.

sc68cal··on VA staff flag dangerous errors in Oracle-built electronic health record
That's what they did. If you read the article, it discussed the whole program as being a change from an in house developed system, to an off the shelf system.

> The program launched in 2018 to replace the aging computer system used across VA’s health care network, which serves more than 9 million veterans, with an off-the-shelf product that could handle many of the same tasks: organizing important information including appointments, referrals, prescriptions and patient histories.

> David Shulkin, the secretary at the time, announced that VA would negotiate a contract to buy the records system from Cerner without competitive bidding. VA leaders said they selected the program because the Pentagon already had purchased a similar Cerner system for the military’s more than 700 hospitals and clinics.

Exactly
sc68cal··on We're committing $6.25B to give 25M children a financial head start
I would much rather tax the wealthy, so that we could create a society where we don't have children who need a "financial head start"

I read a book nearly a decade ago, that I think is worth highlighting.

> The book's central thesis is that members of the global elite are using philanthropic institutions to preserve a system that concentrates wealth and power at the top at the expense of societal progress. Giridharadas examines the narrow limits of modern philanthropy, claiming that rich donors avoid contributing to causes which could undermine their own lofty status. He argues that in some cases, the political lobbying efforts of wealthy donors may reduce the government's ability to address inequality.

sc68cal··on DRAM prices are spiking, but I don't trust the industry's why
> The incentive for one of the big players to undercut the other on cost even just a little bit to pick up market share is extremely lucrative.

I would argue that the DRAM price fixing scandal actually demonstrates that the industry operates like a cartel. During times of low demand and high supply, they will coordinate to protect prices, and then during spikes in demand (or alleged spikes in demand) they coordinate to keep the price from dropping.

sc68cal··on Today is when the Amazon brain drain sent AWS down the spout
From the article.

> At the end of 2023, Justin Garrison left AWS and roasted them on his way out the door. He stated that AWS had seen an increase in Large Scale Events (or LSEs), and predicted significant outages in 2024. It would seem that he discounted the power of inertia

Your comment is relying on that referenced inertia. Things will continue to function for a period of time, but there exists an inflection point at which they no longer function as previously.
