Tomcat/Jakarta EE/JSP is a surprisingly solid stack. I only tried it once. Everything mostly just worked, and worked pretty well. You get to write pages PHP-style (interspersed HTML and code) but with the full power of Java instead of a hack language like PHP. Of course that paradigm may not suit everyone, but you also don't have to handle requests that way as you can also install pure Java routes. It supports websockets. You can share data between requests since it's a single-process multi-threaded model, so you can write something with real-time communication. You can also not do that; JSP code (and of course local variables) is scoped to a request. Deployment is very easy: drop the new webapp (a single file) in the webapps directory, by any method you like e.g. scp, and when Tomcat notices the new file is there, it transparently loads the new app and unloads the old one. You do have to watch out for classloader leaks that would prevent the old app being garbage-collected, though - downside of a single-process model.

Back when they started, lidar cost a lot of money. They could not have equipped all cars with it.

The issue came when he promised every car would become a robotaxi. This means he either has to retrofit them all with lidar, or solve it with the current sensor set. It might be ego as well, but adding lidar will also expose them to class action suits.

The promise that contributed to the soaring valuation, now looks like a curse that stops him from changing anything. It feels a bit poetic.

The Leap Motion Controller came out in 2014 already (11 years ago, wow!) and isn't very expensive. The SDK was lacking in the beginning if I recall correctly, but a webcam seems to be inferior. Technology isn't the limiting factor for a quite some time now. I'm sure many projects existed to translate gestures to MIDI, some less polished, some more polished[0][1].

Reminds me... I even used two PlayStation Eyes (EUR 5 each) with OpenCV and the EVM algorithm[2] on a ThinkPad X230 for a dance performance piece back in 2015. Movements rather than gestures and OSC instead of MIDI, but it worked great!

“The Miyawaki Method of micro-forestry is a viral sensation: sprouting tiny, dense, native tree cover in neighbourhoods all around the world. With the promise of afforestation at a revolutionary speed, this planting technique has become the darling of green-space enthusiasts, industry, and governments alike — yet few professional or academic ecologists have commented on its efficacy, or even seem to have heard of it!

In this episode, we debate the legacy of Dr. Akira Miyawaki: the man, the myth, and the method.”

If it’s manufactured it implies intent. Someone at Microsoft is doing it on purpose and, presumably, thinks it’ll benefit them. I’m not sure how this can be seen as a win for them. They invested a massive amount of money into buying all those game studios. They also admitted Xbox hardware is basically dead. So the only way they can any return on that investment is third party hardware: either PlayStation or PC. If I were to choose it would be pc for MS. They already have game pass and windows is the gaming OS. By giving business to Sony they would undermine those.

I don’t think nVidia wants gaming collapse either. They might not prioritize it now but they definitely know that it will persist in some form. They bet on AI (and crypto before it) because those are lucrative opportunities but there’s no guarantee they will last. So they squeeze as much as they can out of those while they can. They definitely want gaming as a backup. It might be not as profitable and more finicky as it’s a consumer market but it’s much more stable in the long run.

> Give plenty of credit to the juniors when they do good work, even if they were reliant on support, with no need to take credit myself

This is one of the most effective ways to lead because it builds goodwill and trust on the team. It also takes almost nothing away from you because as the senior/leader you will get default credit for most everything. It's always odd to me more people don't realize this.

I think the person who initially did bring up the phrase must have meant it the way I did, because if they didn't -- if in fact all they meant by it was "basic but obviously important questions" -- then there would be no reason for them to bring it up at all, since 100% of people already agree that you should never be afraid to ask basic but obviously important questions.

My personal experience with n-back mainly revolves around discovering the large variation in my ability to focus. Practisibg does get me better at the n-back task (not anything else as far as I can tell) but daily form determines results to a large degree. This effect seems to transfer somewhat: on weeks I'm overall worse at focusing on n-back I appear to also produce fewer commits.

But what determines this daily form I don't know. I suspect sleep, stress, and exercise has something to do with it.

> This discussion is about growth and change over time as a person.

Is it? Because the original statement used the word "never" and didn't mention growth and change over time as qualifiers.

The more one attempts to qualify -- that is, restrict the scope of -- the advice, the more one tacitly admits the point I'm trying to make, which FTR is: This advice is not always good advice.

As another commenter pointed out, Death Stranding focuses on the travel experience, where you have to plan your route according to how much 'effort' and risk you want to take.

Back when there was Morrowind, which didn't have map markers and whose in-game map had to slowly be uncovered. You get a description and that's it. The game did come with a paper map, which was stuck to my wall for years and frequently consulted.

A modern one would be Kingdom Come: Deliverance 2; when you turn on hardcore mode (which was only added after release, but the game was designed with it in mind), you don't get your position on the map, compass, or map markers; every quest involving a location has the NPCs give you a description (and at least in normal mode, your character making a remark when you've reached a landmark). It's not so much about planning your route though.

There's a precedent:

https://en.m.wikipedia.org/wiki/Uganda_Scheme

A typically British bad idea.

Another one might be transmigrasi: https://en.m.wikipedia.org/wiki/Transmigration_program

A bad Dutch idea, carried out forcefully by the Indonesian government for decades.

A point to keep in mind: the Palestinians don't want to be relocated. So, it's both contentious, and probably a (war) crime. Forced relocation has a long, torrid, bad history.

exactly this. these people dont understand that their own speculatory practices are what makes this a terrible store of value. its unstable, they even have to rely on literal stable-coins but they still dont see the problem

for the sake of argument, is there any way to introduce monetary policy into crypto currency so as to correct for unwanted inflation/deflation? without compromising on its decentralization promise

We do. We also have wolves about. In the last year there has been a grand total of one sheep in the entire district possibly lost to them.

Wolves, like many other apex predators, have been selectively bred over generations to be avoidant of humans and livestock, as the consequences are typically mortal, and remove those tendencies from the germline.

Same kinda deal as why we no longer have ducks here that aren’t scared shitless of human presence.

But to GP's point:

> To those whose time is limited: you may wish to stop reading here. If you seek to improve your life, and want the greatest ‘bang for the buck’, you are well-advised to look elsewhere.

> Meditation, for example, is easier, faster, and ultra-portable. Typing training will directly improve your facility with a computer, a valuable skill for this modern world. Spaced repetition memorization techniques offer unparalleled advantages to students. [Lots more.] And all of these can start paying off immediately.

> DNB, on the other hand, requires a minimum of 15 hours before one can expect genuine somatic improvements. The task itself is unproven - the Jaeggi studies are suggestive, not definitive.

It’s a bit mixed, by 1990 most UNIX vendors were moving to various RISC architectures so a 68k based workstation would appear rather old fashioned for that market. People paid Serious money for a UNIX system to do Serious work, so why cheap out on yesterdays technology?

A/UX didn’t seem to do that well in the market either.

So you are contradicting what Luke Nosek, the co-founder of PayPal, said?

Luke: "Many people don’t know this, but the initial mission of PayPal was to create a global currency that was independent of interference by these, you know, corrupt cartels of banks and governments that were debasing their currencies.”

Why should we believe you and not the person who created PayPal?

It was floated a few weeks ago they this tax break's disappearance was responsible for mass lay offs in tech.

Other theory were AI and interest rates.

I'm pretty sure next rounds of layoffs will have another "good reason".

Personally, I'm still partial to my pet and hard to document theory of "when headcounts go down, share prices go up - and past a certain size and age, the goal of a massive corporation is not to build things any more, but to pay for retirements through the resale / buybacks of shares"

But, hey, BBB is singed, so everything will be awesome soon, I suppose ?

Perhaps another way to think of it, is what would it take to be less disillusioned?

What was about it that made you think it might be a good thing? Have those aspects gone now or is the problem that there are new factors that put you off it?

Most importantly, what could be done to get you back onboard with the idea? I'm not really a fan of "Bad thing is bad" and like to think in terms of "This thing has a bad aspect, what could be done to fix it"

To my mind, I was not expecting Bitcoin to increase in value this quickly. Few people probably were. On the other hand if the end point of Bitcoin was to replace money, then I can see how it would have a high value at that endpoint. That presupposes that it reaches that endpoint. The perceived value (barring the mood based fluctuations of speculation) depends on the proportion of people who believe in that outcome and when they think it will occur.

When Bitcoin came out I thought that it was indeed like email for money, and that it would take a similar amount of time for it to be used by people in general. I figured it would be 20 or 30 years before the average person had even heard about it. Turns out I was quite wrong there.

I don't think Bitcoin is particularly impressive as an investment today, the risk when it comes to retaining value is some unknowable but probably quite high. The risk of holding and retaining your balance adds another layer to that. For the value of the mining reward to stay level with an external currency there has to be around a 20% increase per year to keep up with the halving. Exceeding that rate is what lead to the increase in energy expenditure. While it has increased more than that so far, the one rule of exponential growth is that it cannot continue forever.

It might have a few doublings left in it, but it is slowing down and with a risk level where you could probably find a lower risk way to double your money in a similar timeframe. Maybe it hits a million, but when? If it takes long enough you're better off with an index fund.

Bitcoin sits around $100,000 today, that's way higher than its current utility. I feel like the value should represent the aggregate impression of where Bitcoin will be in the long term. I mostly think this is true and bubbles represent the flow and ebb of the faith that has no logical support. I used to think that nobody could sustain the delusion of value when it is not apparent for many years on end. House prices have led me to think that maybe people can pretend that their thing is worth more than it actually is for many years without faltering.

I guess the world is in a funny place now. For even an index fund to be long term stable, some counties have to continue to exist, and people are beginning to have doubts about even that.

From time to time I use an LLM to pretend to research a topic that I had researched recently, to check how much time it would have saved me.

So far, most of the time, my impression was "I would have been so badly mislead and wouldn't even know it until too late". It would have saved me some negative time.

The only thing LLMs can consistently help me with so far is typing out mindless boilerplate, and yet it still sometimes requires manual fixing (but I do admit that it still does save effort). Anything else is hit or miss. The kind of stuff it does help researching with is usually the stuff that's easy to research without it anyway. It can sometimes shine with a gold nugget among all the mud it produces, but it's rare. The best thing is being able to describe something and ask what it's called, so you can then search for it in traditional ways.

That said, search engines have gotten significantly worse for research in the last decade or so, so the bar is lower for LLMs to be useful.
Ask HN: How to pivot to new ICP or Industry?
by jurissoftware | 2025-07-05 08:19:58+00:00
I have read so many stories about companies pivoting to something new completely and finding the PMF.

We followed YC book on interviewing people, operating a service, then building product. But, we are finding out (painfully) that people don't want to pay for our SaaS. There is just not enough demand. Since you can't sit idle to make money we have spent 8 months to build two small products. We dont have integrations yet but we have core tech that works well. We have single digit customers but we are not growing at all. We had zero sales for last 3 months. The month before that were not good as we had only one or two purchases.

We want to pivot. All founders agree that pivoting makes sense. But, there is a great dilemma

1) Should we use our tech built so far and find new ICP or Industry who could benefit from this?

This will be best outcome as the code, system, branding wont become throwaway. It take HELL LOT OF TIME to do branding and earn trust. Throwing it out will be starting from zero again.

Or

2) We should let our tech and systems go and pivot to new industry and build again?

We have adjacent industries in mind. We haven't done customer discovery yet in this area and this will be our next step. We won't build until we validate the demand. While we may have to throw away the tech and systems, we will be looking to solve problem with fresh eyes. No baggage and no carryover of thinking patterns.

How to choose between two? What do you suggest?

Canada is "much more socialist" in that it has socialized medical insurance. Aside from that, it's maybe a tiny bit more socialist, though one could argue it's not more socialist at all.

The systems are different, but saying they are completely different is really a stretch. There's a GST that the US doesn't have, which is, ironically, a regressive tax. If you ranked the tax code of countries by similarity to the US tax code, I'm not sure Canada would be at the top of the list, but it wouldn't be that far down.

What a miserable world people commenting here seem to live in where going out to dance is a sort of status challenging activity?! When I was younger and frequented dance floors, everyone immediately started dancing as soon as the music started playing, wasn’t that the point of being there?? Never even occurred to me to fear being the only one dancing. And if did happen I would be wondering what kind of people come here and just stands there.

I think using an experimental file system is actually perfectly fine for the root partition, as long as it doesn't include `/home` and you keep a USB stick in your drawer so you can reinstall whenever it loses data.

I'd be highly conservative about using it for my home directory though. Or at least make a subfolder where all my really important files (legal documents, master thesis, etc.) go and mount that on another partition that uses a more conservative filesystem.

Remember when we software engineers painfully learned to _not_ do massive releases with hundred of changes that are guaranteed to create bugs ?

Well, imagine if instead we were _incentivized_ to create lots of bugs in huge releases, because it helped us ship that one important feature that the PM wanted in the middle of the garbage - and also, that we were guaranteed never to have to debug the software ever, and god forbid, to use it ?

Claude Code makes me feel like I'm dispatching a legit engineer to go get something done. But they come back in a minute instead of a week. Most of the time the solution gets the job done. Sometimes it introduces too much complexity, sometimes it's totally wrong, but it gets the job done. Cursor meanwhile just feels like shortening the (copy editor/paste chat/copy chat/paste editor) loop.

For $200/month you can get equivalent value to a team of engineers. Plan accordingly! The stack is no longer safe for employment. You need to move up to manager or move down to metal.

> delete entire unit test file & have claude generate a new one

Why not just add new tests or refactor the existing ones? Seems kind of silly.

Aside from that:

- if you don't like AI tools and can afford to do so, then look for a place that matches how you want to work - if you do like AI tools, or are open to learning them, then there isn't an issue (aside from maybe how they're used)

There isn't much more to it: https://blog.kronis.dev/blog/ai-artisans-and-brainrot (bit of a rant of mine on the topic, the tl;dr would be that the cat is out of the bag in regards to these tools and there are both positives and negatives, but they lead to brainrot and degradation of skills the same way how IDEs and StackOverflow did, just a large leap further)

Let's be honest, this is us taking a few terms from a few neuroscience and cognitive psychology papers and running with it.

There are two claims in this post: Initial goals get adjusted as we discover operating constraints, and it is easier to work with fewer variables to pay attention to.

I didn't like these sentences in this post:

- "I see this in wannabe <people trying>..."

- "Here's what happens to those brave enough to actually begin ..."

Here the author was brave enough to put themselves on a pedestal; like a true wannabe profound.

Luckily we can reuse system prompts :) Mine usually contains something like https://gist.github.com/victorb/1fe62fe7b80a64fc5b446f82d313... + project-specific instructions, which is reused across sessions.

Currently, it does not take the same amount of time to prompt as if I was to write the code.

The people who give him credit are the same people who sold PayPal for $1.5 billion in July 2002:

Peter Thiel, Max Levchin, Luke Nosek, Reid Hoffman, David Sacks, Ken Howery, Jeremy Stoppelman, Russel Simmons.

Elon was removed as CEO in 2000, but he remained the largest individual shareholder when PayPal went public.
