wjnc··on Should a medical diagnosis reshape the past? (2025)
What a wise reflection and a powerful concept of 'moral accounting' as something to not hold on to. The Tao of Pooh has left my hands seconds ago. The 1983 paperback first edition, with yellow pages than smell of sweet old paper. Thank you for reminding me of that gem.

The thing with loss and emotional maturing is that it is a long and painful process. To try to answer the question "Should a medical diagnosis reshape the past?":

Yes, for all the love you have. Let it. Even if it's false. Narratives that help you find peace and understanding are what you need. Think deeply on that the position of the father /might/ be right, but even false can be a wise position. It is so unlikely that a mother held her child and not loved the child fully and with the intention to raise it right. Circumstances (medical, life, ...) can get in the way. But hold on to that intention.

And we have to be honest: both agents will misuse users and the other way around. So you are asking Anthropic for a backing that will also get stress test by meatspace. I do like the idea: a prepaid or restricted amount credit card for agentic purposes, with the novelty being that amounts above threshold have some kind of protection within consumer law.

Thank you for your time and knowledge.
wjnc··on What we know so far about Spain train crash
Would you mind sharing some more of the why it is still an open problem? (I know I know little about this subject.) I understand satellite positioning isn't definitive and did not suggest it should be the /primary/ risk mitigating factor. But even as a tertiary or lower risk mitigating factor, this would have been a worthwhile investment. (Sorry for the bleak introduction of economics.)

And some problems are just _open_ to outside looks. My assistant tells me that the room for error in trains on one dimension ('left - right') is mere 10s of centimeters. I understand that problem. But what track you are on, isn't that obvious to the human in the cabin? (Again, simplifying, not flaming. Production ready safety is _hard_.) So could a vision based solution help count tracks from left to right? (Assistant: "US PTC, on about 54,000 route-miles, uses GPS for the lead locomotive plus crew-entered track information and switch position".) So you use the dimension that matters most in crashes (forwards / backwards) from satellite, augmented with vision or human based left-right positioning. Some trains already have sensors to sense things like leaves on the track to adjust speeding and braking... So the sensor based approach is already there.

Perhaps I am read as suggesting that the problem is easy, and that is not my intention. But for cars this was solved decades ago for routing and years ago for self-driving. I use that daily. Flying is organised with a very clear 6 sigma approach. Crashes are nearly always situations where events / risks stack. Trains (in Spain)...?

Tl;dr - Safety is a function of (human; process; technology) and there is clearly something lacking for trains, when compared to other types of transport.

wjnc··on What we know so far about Spain train crash
I would argue that we should look at systems-level explanations. The human factor is so glaring we can get caught up in it. There are what, 50?, high speed trains in movement in Spain at the same time. Even GPS + Starlink + 1 monitor (is that 50k€?) could have prevented this. But it happened, and the question is what is going on with train security in Spain in general for people to (be able to) make such decisions.
wjnc··on The 'else' keyword is probably a literal translation from German (2020)
Forgive me for trying it out on you:

“Er trinkt heute Kaffee, sonst trinkt er nur Tee.”

wjnc··on The 'else' keyword is probably a literal translation from German (2020)
As a non-native speaker of both English and German, I feel a little difference in usage. I liked this bit of slop:

‘The most significant nuanced departure is that "sonst" can mean "normally," "usually," or "in general," contrasting a specific event against a baseline of normality. "Else" cannot do this.’

There is an etymological root to ‘sonst’ that is also the root of English ‘thus’. The German explanation would fit well in this story (but indeed no evidence presented).

wjnc··on How to grow a cacao tree at home (2024)
Can I just add that this commercial website is great. It's informative. It has lots of information. It's very clear to read. And the blog just breathes loving the product.
wjnc··on IBM CEO says open weight models are now good and cheap on-prem
This being /u/jacquesm would imply it is kinder to assume him having that setup than claiming to have that setup.
wjnc··on Tiny Little Office
I am placing your time of digital fruition in the 00’s or later? Not bashing, but we bought floppies in the 80s with software with no updates. Cool kids got their software from Oh No More Warez + keygen in the early 90s. That went online in the late 90s.

Always online, internet of shit and perma update crap came at that same time, first for the OS and later for everything. Oh, plus two decades of using shady Russian software for virus scanning. Shit went up, update everything became everywhere and everyday. Plus gigabyte frameworks for functionality that was kilobytes before.

My point in cursing too much? (Sorry, mentally screaming FUD here.) That tiny code projects, even without an active maintainer, in the LLM-era are probably a lot more secure when run by the people they target (we run containers, and sandboxes, the cool kids run immutable distros). This is democratizing software, and it has the great feel of old.

Please everyone, vibe code tiny project with tiny codebases everyday. Dump them on GitHub in a free tier. Make so many that the people have a free choice again! And go watch Cliff Stoll again for that hacker energy!

wjnc··on Sorry, I'm in a meeting
How do you expect a hierarchy to function? Should the assistant to the SVP ask the managers to let the employees reschedule? That’s like a lot of bureaucracy for exactly the same flexibility.

(Am open to better approaches though! Not saying I particularly enjoy last minute urgent meetings you can’t say no to. But most often those are important and with people whose agendas need more care than mine.)

wjnc··on Don't be fooled–LLMs don't reason
This just reads so anthropocentric to me. Humans are wired to see intelligence only where intelligence is human-like. We see autonomous action-response and planning as the keys to intelligence. I would expect that, dear primate based Homo sapiens.

We are experiencing non-humanoid intelligence without AGI. That is awesome. And we don’t have a clue how to protect ourself from AGI.

Likewise, we intelligent primates have this great system of coordination called market economics that lets us destroy our home planet with our eyes open. That’s what we call intelligence!

(Not 100% personal opinion and deliberately inflated from the I’ve been thinking about.)

wjnc··on Suits Are Better Tech Than Modern Clothes
Wasn’t meaning to insult, sorry. Didn’t take the lowest interpretation though (“performative”, “clown suit”). And I didn’t go for the ad hominem about men in sweat suites.

I guess we need the distinction of made vs. made to fit (a suit that is tailored post-production) and made to measure (a tailor-made suite; each piece of cloth size for a unique product). Best fitting is made to measure and that is what I am referring to.

wjnc··on Suits Are Better Tech Than Modern Clothes
You have probably never worn a tailored suit. The difference between a good fit and a mediocre fit is in centimeters on the right spots, not the difference between a clown suit and a fitting suit. Tailoring is mainly for fit, not looks. Just the tailoring sessions shows that: about 40 minutes of measurements, and about 10 minutes of choices in wool, in pockets, in model. And to expand on the theme in OP: Super 140 wool is an awesome material on both durability and flexibility. There is a few thousand years of tech just in the wool. (Beat that cotton jeans!)

A tailored suit, but indeed, every tailored piece of clothing will always have the best fit and comfort. That's trivial. Even your sweat suit would benefit from being a tailored sweat suit.

I have non standard measurements and buying trousers has always been a chore (a cm lower shoulder, a 1/2 cm shorter leg, cyclist quads, life influences body). I've now started to use AI to pre-select brands and fits that might suit my sizing. Which is actually just moving somewhat towards at least 'fitted' clothing. The future of adult and sustainable fashion 'should' be made to measure.

wjnc··on I don't want to read what you didn't write
That is exactly how one could describe the relationship between heroin and the users health systems. It’s okay for a little while, until it isn’t but there is no going back. When the risks start telling, lawyers will have a field day. Assisted by LLM’s obviously, which then puts the burden on judges, who then need LLM assistance.

This thing called attention economics has captured my attention quite hard. Digital opiates are everywhere since 10 to 20 years. And in my view, the part that they implicitly of explicitly strive to capture your attention is new.

wjnc··on Gravity Linux Alpha Release: Linux on the M4 Mac Mini with GPU and DCP Support
Let’s take the kind view? If Apple has a problem in a former engineer possibly using insider knowledge that is first and foremost a problem between Apple and said engineer. Reasonably if that first round kicks off, in the second round of problems an OSS project is possible in scope.

The engineer and the project have discussed these risks and decided to continue in a fork from Asahi. So I would say that this is (nearly) how it is supposed to go. Asahi stays clean from contagion and Gravity Linux has taken a, hopefully well considered, risk.

wjnc··on Microsoft exec called AI scraping 'the largest theft of labor in human history'
Creators are unwillingly and contra to economic systems that have evolved over a few millennia entered in the Borg or the Matrix. So their achievements are reused for private and public benefits without their permission. Piracy is theft. And this piracy is a bigger theft than piracy on an individual download basis. Was there any doubt? (Linguistically I agree that you can’t “rob culture”. You can rape or reap culture though, and that is the point at hand.)
wjnc··on Autism is genetic – and why this information matters now
Sorry, I was begging the question and think that’s a bit too private for a public forum.

In general terms my inside pretty much knew that I was neurotypical on quite a few dimensions, but I kept on trying to fit in a normal frame for 40+ years. Accepting these dimensions for what they are (roll the D100) and sharing them to a different degrees in different circumstances (private, social, work) helps me a lot. Turns out friends know you better than you think and that talking about things leads to mutual understanding! While I was long ashamed of being different (to a degree).

An example … I am more “German” than a German. Show me a rule and it ‘fuses’ into my brain. So things like rules and fairness are not for me as they are to most people. This, so I am told, is pretty typical for some people, while most people will literally roll their eyes when I reason mathematically from rules. I think rolling your eyes is not polite and not taking the substance seriously and you can understand how it might go from there. This is also highly hereditary behavior.

wjnc··on Autism is genetic – and why this information matters now
Knowing something you’ve learned to live with for life has a name and by learning that name thus recognizing your ordeal can be very helpful. Neurodiversity is real and learning that you are perhaps somewhat special (not wired like others; perhaps prone to using social tricks as a mask) can help. My personal learning of the last few years. For me the tricks and masks didn’t hurt me, but recognizing how I am and even a bit of sharing that with closest relations helped me massively.
wjnc··on Nike exits the S&P 100 after 18 years and a $200B market-cap wipeout
Can I ask how the shoes created actual orthopedic damage? (I totally understand how hard injury and recovery are, so not flaming. I destroyed my hip cartilage while a happy runner and triathlete, so I know about injuries, recovery and letting go of something I adored and that defined me.)

Shoes * body * mileage = impact, where body gives signs of damage being done and is also the one to work on via technique and strength if something is not going well in your posture. I see the 'duck run' (knee buckling inside, feet moving outside to correct for the loss of height) all the time and would think that something that mostly is related to underdeveloped muscles around the knee.

wjnc··on I Added a Non-Wi-Fi Mitsubishi AC to Home Assistant
This is exactly the case in my household. Excess solar is pretty much worthless here, so with a smart AC you can dump the excess solar into your house as either heat or cold. This (currently) has a lot better ROI than installing a household battery. (Battery tech and availability might change this.)

I am enamoured by making dumb AC's smart by this method, since you probably have a lot less IT risks than by using the suppliers app. I think the trade off is between IT risk and mechanical / technical risk, since adding your own parts have an effect on warranty (or at least: willingness to repair by the supplier).

wjnc··on I resigned from Anthropic today (Jacob Coxon)
Capture a market. Become big enough to jump hurdles XYZ due to scale and amount of, say, lawyers and compliance officers you can field. Then push for more compliance. It’s effectively a moat and one of the most durable kind since lawmakers aren’t very agile. It also opens a second front (first front being: product) to go up against newcomers. Kindly point out to the regulatory agencies that they are not compliant and demand enforcement due to “equal playing field”.

To make this point concrete: KYC in banks in Europe is on a scale of 1000s FTE per bank. No newcomer can ever comply with KYC the way big banks have implemented this by pure meat. Trouble ensue for all newcomer. That’s a moat!

wjnc··on Bill Gates tries to install MovieMaker (2003)
Every single recipient on the thread was a Vice President, Corporate Vice President, or Senior/Group Vice President. Gates intentionally bypassed lower-level product managers and emailed the executive tier directly to demand accountability for platform-wide usability regressions.

If you think this is not missing the forest for the trees, please explain.

wjnc··on Bill Gates tries to install MovieMaker (2003)
Sorry, but board room or top-50 professional discussions are ment to be a lot more meta. Bill using 500-1000 words to voice his concrete experience in downloading an app, with his directors immediately chiming in for fixes misses the forest for the trees. And Bill starts the quest for the one tree in his choice of words. It was disalignment in his organizational model and the CEO is on the line for that alignment. The happy install flow for moviemaker.exe - who cares… Just look at that thread! Response 3 is already “that’s not my turf”-ing. I’m not saying it’s easy to create a shift in a company of that size, it’s that they weren’t trying when the problem was yelling in their face.

(Typing this with a hot lap thanks to Windows update. The agony. Debian solved that 20-30 years ago.)

wjnc··on Hackers have withdrawn ~4k BTC (~$320M) from the Liquid Federation wallet
This is funny. Is this analogous to finding a wallet on the street and returning it (in my locale: and getting a finders fee), or is this analogous to taking a wallet from a drunk sleeping person (morally dubious), contacting them the day after to return the wallet, or is it just stealing per se.

Where I live it's only theft if there is an intention to unlawfully take ownership of the good. As an example, forgetting to pay in a supermarket lies exactly on that boundary. Take a cart or hide a product and you won't get away. Try to pay, payment fails and you don't notice, walk away and get apprehended and you might convince the judge that you had no intention to unlawfully take ownership.

wjnc··on Mark Cuban: Why US hospitals "don't know their costs"
There is no one way of doing cost attribution. So, at scale, there is no such thing as one perfectly calculated cost per product. Hospitals are outliers compared to more regular firms in that they produce tens of thousands of procedures / products. In the Netherlands we’ve standardized products for billing and negotiation purposes but still most negotiation is on a higher level than price per product.

Tl;dr Mr Cuban is right, but I think hospital accounting nears P/NP-level complexity

wjnc··on UEFA's Champions League draw creates unfair clusters; a Cayley graph fixes it
It’s something I like (math and networks) on a subject I like (football) but the AI tone is so heavy I get turned off. It’s far beyond my load-bearing capacity.

(tldr - a subset of teams get paired dispropotionally often in UEFA Champions League when compared to random, lowering average points taken away and thus harming chances for this ingroup and increasing chances for the outgroup; it’s interesting stuff; the group differs per year)

wjnc··on GPU World
In spirit of this conversation - Terence Tao is awesome right? He was already one of the best mathematicians on the planet when he happened to start dabbling in computer assisted proofs (obviously as a giant standing on the shoulders of giants) at exactly the right time for the computer revolution to find a perfect use case (as you point out).
wjnc··on GPU World
I know! And financials and actuaries aren't either. Excel, Python, R and don't know what we can use ducktape and spit for to keep together. But as the LEAN-example quite nicely shows: with the right scaffolding I am convinced the GPU World /could/ look rosy.

An economic problem would be - how could the builder of a scaffold capture _some_ value without right away be copied. The fact that LLMs threw away every protection of intellectual property at their inception makes it a lot harder to invest in (with the goal of capturing some) value. I am at least /somewhat/ influenced by RMS on the 'seductive mirage' of IP but I have my doubts on how copyleft could bring more than breadcrumbs to those who build scaffolds.
