arpinum··on Britain's railway privatization was an abject failure
I'm undecided if privatisation was a failure. I don't know the counterfactual scenario well enough. The article paints a picture that British Rail was doing just fine, making all capital investments necessary, and at low taxpayer cost. I'm somewhat skeptical that it would continue like that for 30 years. Any better analysis?
arpinum··on China intimidated UK university to ditch human rights research, documents show
I can confirm. Russel group universities will grant masters degrees to people who do not show up for lectures, do not possess functional English, and do not perform the coursework. The exams are dumbed down to ensure a high pass rate. Everyone understands their job and pay depends on the international student fees.
arpinum··on Liquibase continues to advertise itself as "open source" despite license switch
I'm ok with saying that Open Source is now widely understood to mean what the OSI says, that's just a function of how language evolves. But we don't need to re-write history to get there.

Open Source isn't a brand, it isn't a trademark, it was hijacked by OSI to enforce their specific interpretation of a phrase that was already in use. OSI wasn't founded until 1998, over a decade after the term open source software became popular and was used throughout the unix and linux communities and in businesses such as Caldera. Before OSI came up with the OSD many creators of open source software had non-compete clauses in the licence.

arpinum··on Flightcontrol: A PaaS that deploys to your AWS account
This could have been some custom cdk constructs. Then at least you can plug in SQS / SNS / DynamoDB / CW / IAM all in one solution. Flightcontrol doesn't seem to offer these.
arpinum··on Heavy codes of conduct are unnecessary for open source projects
I'm not sure how your comment is relevant. No one is fighting for meritocracy here. Only providing the requested information about a case where CoC pushed a specific political view and excluded others.
arpinum··on Heavy codes of conduct are unnecessary for open source projects
Anti-meritocracy was in in some CoCs, arguing in its favour was a reason for exclusion from an event / project. Even if the argument happened somewhere else on the internet and not in the project.
arpinum··on I bought the cheapest EV, a used Nissan Leaf
The EU did put in regulations, but they did the opposite and essentially mandated DRM. They want to prevent owners from turning off nanny devices or overriding pollution controls.

Could be due to American climate and Leafs getting sold heavily in America. Jeff lives in a place hotter and sunnier than Málaga. Cars can roast in their huge unshaded parking lots with black tarmac.
arpinum··on SQLite (with WAL) doesn't do `fsync` on each commit under default settings
This is popping up because SurrealDB was found to turn fsync off by default. But there are important differences:

- SurrealDB provides poor documentation about this default

- SQLite is typically run client side, while SurrealDB is typically run as a remote server

- SQLite is actually full sync by default, but distros may package it with other defaults - SurrealDB explicitly did this for benchmarking reasons (for comparison fairness) while SQLite distros turn off fsync for typically practical reasons as it's run pure client side.

arpinum··on AWS in 2025: Stuff you think you know that's now wrong
I think there is some nuance needed here. If you ask support to partition your bucket then they will be a bit annoying if you ask for specific partition points and the first part of the prefix is not randomised. They tried to push me to refactor the bucket first to randomise the beginning of the prefix, but eventually they did it.

The auto partitioning is different. It can isolate hot prefixes on its own and can intelligently pick the partition points. Problem is the process is slow and you can be throttled for more than a day before it kicks in.

arpinum··on AWS Lambda Silent Crash – A Platform Failure, Not an Application Bug [pdf]
Azure functions don't operate in the same way, they are more like AppRunner's architecture. They then layer on the Lambda billing model.

It was typical Azure strategy of rushing out a product to show they have all the same features as AWS. It may have improved since I last touched it in 2018.

arpinum··on AWS Lambda Silent Crash – A Platform Failure, Not an Application Bug [pdf]
They did, he has writings elsewhere where he says AWS told him it was an application code problem. The sub-title of this screed also says it.

This person should not be trusted to accurately recount a story, I would be sceptical of any claim in the doc.

arpinum··on Mistral OCR
Businesses at scale use EDI to handle purchase orders and invoices, no OCR needed.
arpinum··on Why Northern England is poor
> expense increases due to consultation / public demand have come from demands made on the route between London and Birmingham.

I'm pointing out the problems in the whole country outside London, not just the north. So this includes the demand for 100km of unnecessary tunnels. Tunnels that the create higher risk and uncertainty.

arpinum··on Why Northern England is poor
I'd put less blame on London and more on secondary cities than the author does because he misses an important point: London is the only UK city that tolerates growth.

The UK system heavily centralised in tax-and-spend powers, but heavily decentralised in veto powers. Secondary cities have used their veto powers to either stop development or make it so expensive that very little gets developed.

City centres are not being built up to concentrate talent, and I wouldn't blame London or lack of public money. Housing and rents are high enough to justify private spending on concentrated development if not for the regulatory burdens and delays.

The author points out Leeds and Manchester having no metro system that exists in other similarly sized cities. But how much of a useful metro system could Leeds build given the same money spent by Toulouse or Lyon? My guess is none, the money would be consumed by lawsuits and addressing local veto owner concerns.

HS2 is cut short because of money that people outside of London demand be spent on making it so expensive on a per-mile basis. If the line were developed similar to other lines in Europe there would be money available for the full length.

I'm somewhat bullish on Manchester in the long run, they may emerge as a second city that tolerates growth. If they develop enough to become an affordable and large city then they will attract a lot of businesses who would otherwise be in London.

In my city we have a "housing crisis" while the city council owns large empty lots in the city centre from torn down or empty buildings. They have been waiting 8 years on handouts from London to afford to develop it themselves, spending £15m so far without a single unit built. It could be sold to developers and fixed council finances, but there is such a strong aversion to allowing a private company make a profit. The council actually has assets to develop the sites, but has preferred to pursue handouts instead of spending their own money.

arpinum··on Why Northern England is poor
Factor in the ability to escape bad weather, much easier to do in UK than Denmark .
arpinum··on I have made the decision to disband Hindenburg Research
There are scenarios where these target date funds are not good.

Rebalancing into bonds and mmmfs is a form of insurance against catastrophic losses equities. But if you have a sufficiently large account then catastrophic losses that affect your life are extremely rare, if they do occur they will likely affect your bond portfolio as well, and the expected loss vs 100% equities over 15-20 years is significant, something like 10x the value of the insurance you are buying.

If you want insurance for a large account then long-dated put options 20% of the money are much cheaper.

arpinum··on The Headlight Brightness Wars

Auto companies are violating the spirit of the regs while being technically compliant.

arpinum··on Americans see their savings vanish in Synapse fintech crisis
This is not true for fiduciary accounts, which are covered per principal. So FDIC coverage should extend to all customers if the account was properly declared.
arpinum··on How oxide cuts data center power consumption in half
How long before a VPS pops up running Oxide racks? Or, why wouldn't a VPS build on top of Oxide if they offer better efficiency and server management?

arpinum··on UnitedHealth says data of 100M stolen in Change Healthcare hack
There is competition in the marketplace, see Waystar and Availity.
arpinum··on Why conventional wisdom on health care is wrong (a primer) (2020)
Neither of your links are primary source data and give an incorrect interpretation. If you follow the links to the primary data you will find the phrasing changes from "medical problems contributed to..." in the source to "health care expenses were the most common cause of bankruptcy" in your citation.

The numbers you cite are the percent of bankruptcies that include medical debt. The data doesn't say the medical debt caused the bankruptcy, or that this debt type was the largest percentage of debt. People declaring bankruptcy typically have many types of debt as they generally fall behind on all their bills.

arpinum··on Pine martens return to Dartmoor after 150-year absence
We do need to build and maintain the existing reservoirs that provide water for much of Devon, otherwise we will be shipping it in from Norway. Communities that live in Dartmoor may want to upgrade to more comfortable houses and experience less poverty. A community like Postbridge or Princetown would be severely isolated by 20mph speed limits.
arpinum··on Pine martens return to Dartmoor after 150-year absence
Not good. There is a spectrum of choices between not having enough reservoirs and power generation on one end and paving over the entire country on the other. I would trade having bats confused at night in order to have more housing within 2 miles of a major city.
arpinum··on Jack Welch Screwed Up GE and Boeing, and with Them Much US Climate Action
Six sigma's main push in the 80s was to drastically reduce defect count by diving deep into manufacturing processes, the opposite of the quality issues discussed in the article. It sounds like your experience is similar to what happens to a lot of management philosophies when they get popularised into airport books and watered down.
arpinum··on Jack Welch Screwed Up GE and Boeing, and with Them Much US Climate Action
It's an interesting thought experiment for how Jack would handle the financial crises. I don't think it would play out in the same way. Maybe I'm too much of a fan boy, but Jack would have seen the writing on the wall far sooner than Jeff and had more time to pivot.
arpinum··on Jack Welch Screwed Up GE and Boeing, and with Them Much US Climate Action
A mess of an article, focusing on issues 10 years after Jack left. Ignores Jack's big quality push via six sigma and the hands-on work he did to dive deep and fix quality issues at GE during his long career. Jeff Immelt deserves much more blame during this period at GE, but his name won't get the clicks. Jeff was his own man is was not a puppet of Jack, the two hardly talked after Jeff got the top job.
arpinum··on Just use Postgres
> It is still a database where you store denormalized information and therefore is inflexible to changes in access patterns.

It is flexible and you don't need to know your exact access patterns upfront. It may not be as flexible as your chosen technology, but that doesn't make your statement true.
