Generally speaking these days I think that small planes with manual controls (i.e. your private pilot's Cessna) just aren't capable of going that fast. Most of the planes that will be able to go that fast in a dive will have hydraulically boosted controls if not full fly by wire systems.

However this was a real problem during WW2, and high speed dives killed more than a few pilots. By 1942-43 most fighter planes were able to dive fast enough to get into trouble (500+ mph/800 kph) but weren't designed for it at all. The aerodynamics of supersonic flight just weren't understood at the time. In some cases the design of the plane made it essentially impossible to pull out once you went beyond a certain speed, all you could do was attempt to slow down enough to regain control. The P-38 Lightning was notorious for this. I don't have any specific sources handy but I recall reading accounts of things like pilots bracing their feet against the control panel trying to pull the control stick with all their strength, taking extreme measures like lowering the landing gear to slow down (risking it being ripped off and maybe tearing the whole plane apart), or only surviving due to sheer luck - sometimes the thicker air at lower altitudes would slow them down enough before it was too late.

Nifty to see this. I was recently brainstorming about FOSS satellite tracking tools that could be pressed into service for military operations planning. Stuff ranging from planning attacks when certain space-based sensors have gaps in coverage, to working out minimum requirements for targeting adversary satellites. A lot of budget-constrained forces might be able to leverage SkyRoof to fill this gap.

I think it is about adopting the right framework. A mix of Clayton Christiansen and 5 whys works for me (similar issues).

I start by writing down the big things: In this year I worked at/for/with ....

WHY was I there: I think about the major projects I did.

WHY was I there: I think (and try to verify) the impact #s/%s those projects had.

WHY was I there: I think about the technical and soft skills needed to make that happen.

WHY do I care: I consider if there is any configuration of things that would make me consider doing the project again.

Having to track past performance as a business made this much clearer -- I adopted the above approach to expand out CV, then developed a similar approach for business development templates to explain recent past work.

I sometimes will drop these templates into an LLM and have it work with me to define or identify ways to better communicate.

I do not remember my life and I’m a bit sad about it. Aphantasia is completely fine - I feel like that makes me better at various things. SDAM just feels like mostly downside. It makes it hard to notice the passage of time, or plan for the future. It makes me sad whenever I look at pictures of my kids, but can’t remember them being young like that. It makes me sad that when I am old, I will not have the memories of my youth to look back on.

They're hard for me because the events that a lot of people consider achievements don't really stand out in my memory. Often I tend to forget they happened.

I've solved some programming problems that I considered quite mundane and unremarkable, yet others think it was some great achievement.

While it might have been hard at the time, in hindsight the events seem unremarkable and just me doing my routine duties.

> "Write about a time during your university studies in which you faced a difficult problem, and what you did to overcome it."

I guess the university example I could spin a story about how I failed a subject and had to repeat it and got high marks the second time round. The thing is I probably won't remember the event if I'm in an interview and under pressure.

When I started writing this post, I couldn't think of anything difficult that I had to overcome in my CompSci degree. It took me a while to even remember failing that subject, and in hindsight I don't have any emotional attachment to the event. It just doesn't stand out in my memory as remarkable or interesting or even difficult. I did change up my tactics the second time around and did quite well in the subject, so I have material for a story.

The problem is most of the time I don't even remember failing that subject. Even if I did remember, I'd probably dismiss it as I don't remember it being difficult.

Luck is defined as something happening that was unlikely to happen, so having that in mind that evolution kept happening that is no luck, happens on every living organism (last specimens before extension being the exceptions), that the smarter apes got to reproduce is not luck, it is predictable, that they had to use less muscles if they are smarter is also predictable, that muscles are something primates can give up easier than e.g. liver function it is fairly predictable, that you would prefer to take better care of your smarter offspring is also fairly predictable (not saying it's morally justifiable), and so there are so many aligned factors and feedback loops at play that calling it luck would be a disservice, yes evolution has a slight "brute-force" approach to it that arguably involves "luck" but that it's just a small part of it

I hate to be pessimistic but this is something that CC doesn't seem good at: forgetting the tools that it loves and using the ones you want it to. You might want to try "disallowing" that command(?) explicitly (in addition to adding to CLAUDE.md and/or prompt).

I'm not sure what command is being called to set PYTHONPATH. If my assumption that it relates to a specific command is incorrect the above probably isn't helpful.

Good luck!

I met someone with SDAM who described it in a more striking way.

He said he doesn’t have any “first-person” memories. Most people, even if they forget most things they do day-to-day, and don’t have great “indices” of their memories, can think back on certain times where they remember being there, doing a thing, probably with some visuals associated with that, which can be played back. This person said that none of the things they remember that they did, they can remember personally doing, if that makes sense.

For me, I have scattered samples, like once in a while throughout my life, my brain sort of takes a snapshot and forms a memory. I can imagine myself back in each place I lived, for example, or each place I worked, or graduating from college, or walking on the beach.

A long time ago we made a few experiments about water cooling inside a glass of plastic. It goes from 100°C to 60°C very fast. It's very difficult to get a value over 95°C.

The simple model predicts that temp(t)-temp_environment is an exponential and then if you graph log(temp(t)-temp_environment) should be a line. But if you run the experiment it's curved a goes down very fast until 60°C and then it's a line as the model predict.

Our 23-year old son died two and a half years ago and while I'm sure SDAM helped me to get through the horrible immediate times, it's quite sad to be without a lot of detailed memories and events that I can look back on to relive the good times. On the whole, I'd rather have had a functioning episodic memory. (and my son)

> Array programming is similar to functional programming – the primary way to control execution involves composition of functions – but APL tends to encourage the reliance on global properties and sweeping operations rather than low-level recursion4.

This AoC solution is, indeed, quite the functionista! Better yet, it leans heavily into point-free expressions. The style is pretty popular amongst APL language enthusiasts and puzzlers.

That said, you actually see quite different APL styles in the wild:

- Pointed declarative style, also a popular with functional programmers (e.g. anything like this[0] from the dfns workspace)

- Imperative, structured programming, very common in legacy production systems (e.g. this[1] OpenAI API interface)

- Object-oriented, also common in somewhat newer production environments (e.g. the HTTP interface[2])

- Data-parallel style (e.g. Co-dfns[3])

Heck, APL even has lexical and dynamic scope coexisting together. IMHO, it's truly underrated as a language innovator.

From science fiction author Charles Fort in his 1931 book titled Lo! “If human thought is a growth, like all other growths, its logic is without foundation of its own, and is only the adjusting constructiveness of all other growing things. A tree cannot find out, as it were, how to blossom, until comes blossom-time. A social growth cannot find out the use of steam engines, until comes steam-engine-time. For whatever is supposed to be meant by progress, there is no need in human minds for standards of their own: this is in the sense that no part of a growing plant needs guidance of its own devising, nor special knowledge of its own as to how to become a leaf or a root.

Oh, wow, there’s a term for this?

I, too, lack episodic memory for anything that wasn’t extremely emotional —- but have extremely strong semantic memory. As well as memory of specific occasions or patterns being linked to a spatial sense (which in turn relates to vague visuals —- colors and textures; spatial relationships; sometimes a very blurry visual snapshot or one with blank gaps in it; but not actual images).

The main benefit IMHO is deprovisioning.

With straight up fed you can autocreate users etc but as the relying party you don't know when their access has been revoked. Sometimes this doesn't matter, but... often it does. People come and go all the time in enterprise. You can more accurately show user state in your UI and (crucially) accurately adjust license seats. You can also de-activate API tokens or alternative auth methods the user might have configured to close the loop on security.

Big orgs will pay more for SCIM to avoid having to do user access reviews in the UIs of individual products they have bought. It directly translates to person-hours of busywork and admin burden of executing / tracking that work.

SCIM is much cleaner.

They're cute. They're pretty much harmless in my experience.

They swarm all over the PNW, in season. Don't step on them if you can help it. They're not death newts. I'd be a dead commenter if they were death newts.

They swarm all over the trails in spring, and then they're gone for the rest of the season. That's my recollection of it.

I don't live there anymore, maybe they have evolved into these dangerous death newts. One can hope.

More than just human ingenuity than human political organization. Building modern technology requires all the amenities a moderns state affords it, from capital financing, to complex supply chains, to modern bureaucracy, to rule of law, to a willing populace that can conform to rigid roles. Stuff like that takes hundreds of years to build, not so much from innovation but the accumulation of trust and conformity, and the necessary defences to prevent outside invasions from nomadic warlords like the Mongols.

Thinking of switching from API access to Max 20x tomorrow for a more consistent bill.

Been using $50-100 of Opus tokens through API access per day. Think I’ll hit the Max 20x limits and get put in timeout?

I wish Max could automatically overflow to API access when it times out so I would need to have token anxiety.

The code has few comments but gotta love when you can tell someone was having fun!

I’m honestly impressed that a pure python implementation can beat out vLLM and SGLang. Granted they lean on FlashInfer, and of course torch.compile has gotten incredibly powerful in the last few years. Though dynamic shapes have still been a huge thorn in my side, I’ll need to look closer at how they pulled it off…

Not suuuper relevant, but whenever I start a conversation[0] with OpenAI o3, it always responds in Japanese. (The Saved Memories does include facts about Japanese, such as that I'm learning Japanese and don't want it to use keigo, but there's nothing to indicate I actually want a non-English response.) This doesn't happen with the more conversational models (e.g. 4o), but only the reasoning one, for some unknowable reason.

I have aphantasia, and today I learned that I also have SDAM.

There are benefits. For example, I find that I have no issue forgiving people. It's more work for me to harbor a grudge. I don't relive the burden of that initial pain of betrayal when someone close to me harms me, so it's easy to forgive and literally forget.

Fun fact: My dreams are very rarely visual.

What I would find interesting is if the tech trees of different civilizations, not just in Earth but elsewhere would eventually converge. And if you can reach a point where you can anticipate that, how would that predetermine the relationshp between your civilization today and others in the future, or even better, how would that define the relationship between those more advanced to those behind them?

Ownership costs of the domain names is certainly NOT the correct tool control the problem of domain squatting. Some players like rich individuals or big companies will still have enough wealth to squat as many domains as they like. Meanwhile, others with legitimate needs like citizens of low-income countries and small enterprises, will be priced out of the market.

Keep in mind that domain names aren't used just for naming web sites or services. It's a distributed metadata distribution system with several other uses like mail server config, numerous TXT record types, WKD etc. If you take the stance that only the affluent should be allowed to access those services, it will defeat the purpose of the entire system.

The real problem with the DNS is that its design makes it amenable to economic exploitation. It's true that the system takes economic resources to maintain. I'm fine with paying that cost and don't believe that it would make domain names unaffordable. But ICANN and the others are certainly demonstrating increasingly rent seeking behavior lately.

This feels like a cheap trick to drive users towards Claude Code. It's likely no coincidence that this happened at the same time they announced subscription access to Claude Code.

The Windsurf team repeatedly stated that they're running at a loss so all this seems to have achieved is giving OpenAI an excuse to cut their 3rd party costs and drive more Windsurf users towards their own models.

> For example, I think I may also have mild face-blindness, the difficulty in recognizing faces and linking them with names. Usually, it doesn't cause major issues, and with some effort and repetition, I can learn to recognize people. But the face-blindness really rears its head when I meet someone not-so-familiar in an unexpected place, like random encounters on a train. Since I don't have the usual contextual cues to help me, in these cases I find it very hard to pin down who they are. They go "hey Marco, what's up?" and all I get is the vague sense that I know this person from somewhere. Only when they mention names or other contextual information do I have a chance of allocating them in their rightful place in my mental social network.

Oh man, I don't have aphantasia (though I do have unusually poor autobiographical memory), and things like this happen to me all the time. Even more embarrassing is when I introduce myself to someone and they say "we've met several times before."

This one line (especially the part in parenthesis) hits directly on the heart of the matter:

Lillienfeld likely never actually built his transistor (it would have almost certainly been impossible to build a working one due to material limitations), but he nevertheless described the concept.

An invention doesn't become viable when someone thinks it up, it becomes viable when the material science is there to make it happen. We all wish we had the impossible, and we ponder what we would do if physics were just a little more forgiving. So, when material science advances to the point that physics is no longer the limiting factor, a swath of tinkerers is going try it out, all at once, and a few will get it right.

I think I have a similar mental world to the author (with important differences) but will say a few things:

- My lack of memories of my late mother has left me with untold grief in a way the passing of my grandparents did not.

- Mental health is too focused on the individual and the variation in our behaviour should be viewed not only with regards to our own individual fitness but also the fitness of our group and our kin. Most things that are decried as disorders are understudied in group settings designed to maximise the positives. And I despise people overhyping ADHD etc etc as some sort of superpower.

I don't understand what you're trying to prove. They do exist and I never said they don't. They keep popping up here and there, mainly working in demo conditions against static contrast targets.

My point was that so far, these things are just curiosities with very limited usage and there's no mass adoption. Maybe some, but there's some of everything in this war. All the main uav units that I'm aware of use manually controlled fpvs and there are reasons for that.

It matters if 1) you have long-lived sessions on the application (RP) or 2) the application (RP) does something on behalf of the users and you need to stop that.

For example, say I leave the company. My account in SSO (IdP) gets deactivated, so I can no longer use SSO to log in to the company GitLab. However, without some way to let GitLab know that I'm gone, I might still be able to access repos with my SSH keys or access tokens, and scheduled jobs in my account will still run. Deprovisioning not only lets GitLab know I won't be logging in through SSO again, but also that it should stop the scheduled jobs in my account, and block other access methods.

You're right that depending on what your application does, you might not need it at all.

Unlikely, at least for what I think you mean by "readable" here.

APL isn't really one of these exhibitions of computational simplicity in the way of the languages you mention. It's inventor, Kenneth Iverson, was more focused on the human side of thinking in and using the language.

Forth, Lisp, et al are quite easy to implement, but they require considerable library layers on top to make them useful for expressing application-level logic, even if we just focus on the pure functions. APL, on the other hand, has a larger core set of primitives, but you're then immediately able to concisely express high-level application logic.

Are you looking for a kind of reference implementation for learning purposes? If so, I'd say the best route is just go with the docs. Arguably the Co-dfns compiler is a precise spec, but it's notably alien to non-practitioners.

This I am finding a problem. If you are a senior developer you are leading every day and doing senior things but it is like walking. I don't remember each step I took.

In the performance review you now need to say "On this Tuesday I needed to get from the salon to the baker so I initiated by motor neurone and walked out of the salon. This made me get there in 5 minutes which had the impact of my mum getting her cinnamon scroll" and you have to remember that happened. For those with worse memory this is an extra job. If you don't do it you get discriminated against.

So I think we’re on the same page when it comes to the layperson’s ignorance on the subject, and I agree the term is mostly useless. I also agree that quadcopters aren’t the endgame of future warfare, although I’ve been entirely shocked at how effective they’ve been so far.

I don’t really put much stock in your average person’s take on warfare generally, so I’m not too bothered by the torrent of misunderstanding. You see the same thing with AI/AGI, and much of it is fueled by those garnering for clicks.

I will say I missed in my original response that the OP was taking exclusively about autonomous devices, and in that case I would agree with their take.
