arpinum··on UK bank fined £49M over IT system meltdown
The 250+ page analysis of the incident was an excellent insight into how large IT projects fail: https://www.tsb.co.uk/news-releases/slaughter-and-may/slaugh...

money quote: > This situation has all the hallmarks of business management strong-arming the IT organization into an unrealistic timeline. When business leaders push for overly-aggressive timelines, or regulators ask for multiple competing risk frameworks and excessive after-the-fact incident reporting, this all puts a strain on the delivery organization’s ability to untangle the complexity before ‘go live’.

arpinum··on EDI vs. API
I have not heard this claim either and I work in the EDI space.

No idea why this is on HN other than seeing an EDI company fumble a marketing article so badly while trying to stay relevant.

arpinum··on No evidence for nudging after adjusting for publication bias
Not a great journal if you are trying to publish something with potentially large import. Its reasonable to guess that something is seriously wrong with the study to not get it in a good journal. This publication does not move my opinion on the matter.
arpinum··on Voyager Digital files for bankruptcy
That is a checkbox on the bankruptcy form, it’s not a free text field.
arpinum··on Show HN: Easily Convert WARC (Web Archive) into Parquet, Then Query with DuckDB
Do you see DuckDB as a possible replacement for AWS Athena? Where would Athena still be better than DuckDB + Parquet + Lambda?
arpinum··on Shimano Forces Hammerhead to Remove All Di2 Related Functionality From Karoo
I’ve been reading Ray for over a decade and do not find your comment accurate. He has criticised private ANT, he gives good reviews to Garmin competitors, he has been pretty critical of early Vector pedals. His writing style is focused on specific products and things he can measure. You might not like that he doesn’t go off on rants about the industry or write based on info from his comment section, but that doesn’t make him less trustworthy. I’d go so far to say there isn’t a writer in the sports tech space with more integrity than Ray.
arpinum··on I disabled WiFi on the new Samsung fridge
There are legal requirements for enhanced emergency calling in European cars. Cars must have the ability to alert emergency responders with location data. Don’t expect to be able to disable internet in cars going forward.
arpinum··on Graviton 3: First Impressions
Graviton 2 (c6g) also cost more than the Graviton 1 (a1) instances
arpinum··on TRPC: End-to-end typesafe APIs made easy
I'm not seeing the appeal of this over Smithy, which can target multiple frontend and backend languages. What am I missing? What is wrong with codegen tools? Especially when they help you design strong contracts upfront, rather than ad-hoc API design as their demo shows.
arpinum··on Exposed by a Strava KOM: The Many Lives of a Fake Pro Cyclist
For some reason I thought AA would be a great MLM recruitment area. Do they discourage recruitment for jobs and religion?
arpinum··on Exposed by a Strava KOM: The Many Lives of a Fake Pro Cyclist
Well worth the read, but it left me with so many questions.

How much is self-deception? The conclusion of the article makes me think he believes some of his own lies, as if he starting lying so much he doesn't remember what is reality.

The other characters in the story are equally fascinating. Did the retired general know Clark was a grifter, but was happy to collect a pay check sitting on the board? Can you succeed as a defence contractor without buying influence via board seats?

Did Clark purposely team up with unqualified people as a 'shared complicity'? This makes me think he didn't believe his own stories, as he didn't want people in his inner circle who could call out his lies.

When the female cyclist said she would believe Clark if he said the sky was green, what could Clark possibly have done to have so much control over a person? What percent of the population is vulnerable to being sucked into obvious lies?

MLM scams, politics of the Big Lie, investment scams, prophets, miracle cures, etc. The world seems full of these horrible people. How can we help our friends and family avoid being victims if these scammers have such strong powers of persuasion?

arpinum··on Energy Trends UK, October to December 2021 [pdf]
> When a good chunk of factories shut down

Do you have a source or way of quantifying the claim of the amount of factories shutdowns and the primary cause being energy prices?

arpinum··on The Dec/Compaq Turbo Laser 6 AlphaServer KN7CH Processor
DEC didn't have it in their DNA to compete on price and deliver 'good enough' solutions. We praise them today for these fantastically robust boards and very clean power delivery, but in the end it destroyed the company. Ken Olsen was wilfully blind to the PC revolution, mainly because he knew he couldn't get the margins needed from home users for his over-engineered designs and expensive sales teams.

arpinum··on You and the planet need a heat pump
Modern heat pumps, for example by Mitsubishi and sold in the UK, maintain a COP > 2.5 at -7C.
arpinum··on UCLA hiring Asst. Adjunct Professor “on a without salary basis” (PhD required)
I remember a department head telling me they got offers constantly from people willing to be an adjunct for free. Why? Because it would boost their credentials when doing other work and consulting.

The math is easy to figure out: if you spend 75 hours a year as an adjunct to increase your day rate by $100, then your time as an adjunct is worth up to $250 / hr.

arpinum··on Incident with GitHub Actions, API requests, Codespaces, Git operations, Issues
Github Actions does not have good track record. https://www.githubstatus.com/history . You don't need a majority of GitHub users to understand it's owned by Microsoft for there to be an impact on brand value.
arpinum··on Incident with GitHub Actions, API requests, Codespaces, Git operations, Issues
These incidents have to hurt Azure's brand value. It's a monster task to run something as big as GitHub, if they ever get it stable it will lend a lot of credibility to Microsoft's cloud skills.
arpinum··on Over 10% of Tesla Model S EVs Fail Germany’s Strict Inspection After 3 Years
Author lumped together suspension and headlight problems, we do not know the split between these two issues, but they carry vastly different consequences
arpinum··on Over 10% of Tesla Model S EVs Fail Germany’s Strict Inspection After 3 Years
Article fails to mention how many of these defects are due to low beam alignment issues, which is normally a quick adjustment done by dealers before the inspection. Article writer likely knows what they are doing and disguises the numbers.
arpinum··on Police in tiny Alabama town suck drivers into legal ‘black hole’
State constitutions should be updated to force all revenue and assets derived from fines to be distributed equally to all residents. That would distribute the benefits widely enough to remove the current incentives where fines line the pockets of local police and fund town operating budgets.
arpinum··on “Chatbots: Still Dumb After All These Years”
Like early mainframes, not every task is a good fit for emerging tech.
arpinum··on “Chatbots: Still Dumb After All These Years”
The initial dialog tree and year of “improvements” were done by IBM themselves.

The main issue was that it was a vanity project for a stakeholder, which they used to pivot into a new job / career as a “thought leader”

arpinum··on “Chatbots: Still Dumb After All These Years”
I saw the development of a chatbot based on the IBM Watson stuff. It was just like a phone tree map, except the system tries to guess the option selected based on the intents found in the speech/text. Of course it got no adoption, except when forced on users to drive metrics.

It was enormously expensive, it would have been cheaper to have a human on the other end.

arpinum··on What makes EDI so hard?
FHIR will take over, but I wouldn't call that a good thing. the development of FHIR is extremely haphazard, most of it will turn into a generic KV store and miss a lot of the great systems thinking in EDI. It's as if they lowered the barrier to entry at the expense of robust document exchange.

Hopefully Stedi can make adopting EDI easier and increase its popularily over the next 50 years and there isn't such a demand to create alternative systems.

arpinum··on AWS us-east-1 outage
This is not true. Lambda updates us-east-1 last.
arpinum··on AWS Amplify Studio: Figma design to full-stack apps
Amplify constantly under delivers. Features are built only enough to make a demo. Now they say they can go from design tool to working app, where dozens of companies have failed over the last 25 years. Call me skeptical.
arpinum··on Living with single-tenant and multi-tenant architectures
I do, but the techniques are different. Adjacency list are the primary tool. But there is generally a lot less normalisation. Keep related data in the same item or next to each other in the list. Sometimes you over-fetch and filter for the data you need client-side.
arpinum··on Living with single-tenant and multi-tenant architectures
This is a great reminder of all the problems I don’t think about because I use Lambda, API Gateway and DynamoDB. I still think a lot about IAM policies and queuing systems, but scaling compute and databases are no longer a concern.
