People seem to dismiss the value of humility and frugality nowadays, but I see them as important virtues that lead to a more enjoyable life.

For one, I like to have a connection with the place I live and the physical objects I use like my car and home- the fact that they are old things I fixed up and maintain myself gives me a sense of place, connection, and pride- just buying something expensive that someone else prepared for me would feel infantalizing and unsatisfying.

Also, I think a lot of consumerism and conspicuous consumption comes from a sad and depressing place of anxiety that you aren’t good enough to make friends or find romantic partners without doing this. But this inevitably means resigning yourself to essentially buying the company of people that don’t actually like you. At the extreme end you see someone like Donald Trump, so anxious about not being perceived as wealthy enough that you glue fake plastic gold on everything you own because you’re afraid of looking poorer than billionaires.

I guess to truly calculate it you need to estimate how long it will take to get the ROI (i.e. reach the point where you need to pay taxes on the 150billion). And add back what you can earn by investing the money you didn't have to pay taxes on. I'm not sure what the magnificent 7 can expect as a ROI on invested money though, given that they tend to have enough cash to invest anyways and just pay out dividends.

> ram scavanged from an old 486 (edo ram)

EDO was from the 2nd generation of Pentium. It was not a 486 thing and I never even heard of any 486 that could use EDO.

The 1st gen Pentium chips were 5V parts running at 60 MHz or 66 MHz.

The 2nd gen were 3.3V and ran at 75, 90 or 100 MHz.

The critical development for EDO was Intel's Triton chipset (the 82430FX) which added EDO support for about 15% more memory bandwidth.

I ran the testing labs for PC Pro magazine at that time and Tulip Computers of the Netherlands sent in a Pentium with an SIS chipset that could detect EDO but not use EDO's timings, so it was no quicker. I wrote about it.

(This was circa 1995. 486 introduced 1989. P5 (5V) 1993. P54C (3.3V) 1994.)

Tulip threatened to sue. The board and some lawyers flew to London. I demonstrated that their PC could detect EDO and showed a message that EDO was fitted which did not appear if FP-mode DRAM was.

I then showed that a machine with a 430FX chipset was circa 15% quicker with EDO than FP RAM, and the Tulip was the same speed.

The threat of litigation was withdrawn and Tulip used our phone to make an international call to Taiwan there and then to shout at SIS.

I worked extensively with this stuff.

No 486s with EDO to the best of my expert knowledge.

I am afraid of trying to lift to failure.
never once been in a gym, or trained for anything except marksmanship, but have alwayse been physical, with a lot of what I call "dirty lifts" in the course of getting things done,pushing 60 now.
I do notice that after a stretch of realy hard work, and taking a day or two to rest and EAT, I will bulk, but nothing is by the numbers, except the day I took over the old blacksmith shop and we took the gentlmans anvil down, and lifted mine up, each of us grabing one end with one hand, my anvil weighs 460lbs, he was in his 80's and I was in my late 20's.
I muscle everything around, steel, wood, round bales,but follow the philosophy of "just because you can, dosn't mean you should"
which I believe is especialy true for realy big guys, because while you can build huge muscle, your cartlige and coligen is no better than an size small office guy with that florecent tan, where I have seen in the same frame, a big guy pushing 40, not moving good anymore, and foccused dweeb gettin his lunch zipps right through, doesn't even see the hulk.
my point, if I have one, is that nothing counts, unless you can style it

One takeaway from the book is that trend following strategies are really difficult to follow. Jesse Livermore had a 3 yearlong losing streak from 2011 - 2014 despite him following his rules. After the events of the book, he went short in 1929 and was reportedly worth over 100m in that time, a huge amount. Then he lost it all in the strongly mean reverting markets of the 1930s where his trend following strategy didn't work.

He was a problem gambler, but I think if we looked at top poker players of today, they'd all have some love the gamble in them. Jesse had godly tape reading skills that allowed him to beat the bucket shops at the start of his career.

After being kicked out of the bucket shops, he should have just become a floor trader and in all likelihood, he'd have had lower highs but would have fared a lot better overall. A lot of the trading cliches like cutting trading losses quickly, letting profits run, averaging up rather than down originate from this book. There is a reason people still talk about it 100 years after its publication. It's a good contender for the best trading book of all time.

I've been manually copying responses between chats when I hit token limits, and I'm wondering - have you considered a multi-AI consensus approach instead of persistent memory?

The idea: multiple AIs (Claude, GPT, Gemini, Grok) brainstorm simultaneously and produce one agreed response. This might solve the context problem more elegantly because:

- No token limit anxiety - you get comprehensive answers upfront
- Better quality through AI cross-validation
- The consensus answer naturally becomes your context
- Simpler to implement - just parallel API calls vs memory tree management

Just curious if you've explored this direction or if there's a reason the memory persistence approach works better for your use case?

Pi not multiplied by 2 has only one application, which is ancient. For most objects, it is easier to measure directly the diameter than the radius. Then you can compute the circumference by multiplying with Pi.

Except for this conversion from directly measured diameters, one rarely cares about hemicycles, but about cycles.

The trigonometric functions with arguments measured in cycles are more accurate and faster to compute. The trigonometric functions with arguments measured in radians have simpler formulae for derivatives and primitives. The conversion factor between radians and cycles is 2Pi, which leads to its ubiquity.

While students are taught to use the trigonometric functions with arguments measured in radians, because they are more convenient for some symbolic computations, any angle that is directly measured is never measured in radians, but in fractions of a cycle. The same is true for any angle used by an output actuator. The methods of measurement with the highest precision for any physical quantity eventually measure some phase angle in cycles. Even the evaluations of the trigonometric functions with angles measured in radians must use an internal conversion between radians and cycles, for argument range reduction.

So the use of the 2*Pi constant is unavoidable in almost any modern equipment or computer program, even if many of the uses are implicit and not obvious for whoever does not know the detailed implementations of the standard libraries and of the logic hardware.

If trigonometric functions with arguments measured in radians are used anywhere, then conversions between radians in cycles must exist, either explicit conversions or implicit conversions.

If only trigonometric functions with arguments measured in cycles are used, then some multiplications with 2Pi or its inverse appear where derivatives or primitives are computed.

In any application that uses trigonometric functions millions of multiplications with 2Pi may be done every second. In contrast, a multiplication by Pi could be needed only at most at the rate at which one could measure the diameters of some physical objects for which there would be a reason to want to know their circumference.

Because Pi is needed so much more rarely, it is simpler to just have a constant Pi_2 to be used in most cases and for the rare case of computing a circumference from the diameter to use Pi_2*D/2,

This is an over-complicated post for hn. You have already been flagged, because reality is complicated and many (not all I guess, but many) SV types are interested in simplistic views only, preferably where the US and its allies are the Good Guys (and so are the "cool" miltech companies).

I would say though it doesn't boil down to materialism; obviously religious fanaticism plays a huge role in projects such as Israel's destruction of Palestinians.

I bought a riding lawnmower used, 17 years ago. The mower was very well maintained, engine was good, and already 25 to 30 years old when I bought it.

I wanted the manual.

Sears parts still existed, and they shipped me a complete copy of the manual(photocopied) for 10 bucks.

Manual listed all parts, breakdown, etc. I was able to confidently order parts, keep it running for a decade.

That was one reason Sears was so liked.

(for reference, my new mower manual has as much detail, I checked before I bought)

I can both dislike the Israeli government and want for the Israeli population to be protected against missile and drone attacks.

I can both dislike Hamas and want for Palestine to be free.

Is it that hard for you to imagine that people just want to be safe? This is not a football match where you pick a side and then hate on the other side! Stop doing that! These are real people. If groups shoot stuff at Israel of course they're going to try to shoot that stuff out of the sky.

The people can solve this. Cut the states burn rate at least 10% every year and also remove 10% of laws every year. Let the citizens choose which programs and laws to cut using a government web portal. In 10 years cap the taxes to a max rate of 3% and require $500 million in programs to be removed for every $200 million in new programs added. Require every new program to list on a government web portal exactly who is allocated how much money and show exactly how every dollar is spent with receipts. Use AI to figure out where money is being mismanaged and instantly pause the program and funding until the issues are resolved.

Cute! I actually like the one, referenced at the end of the paper that's linked in the post, where they use a physics experiment without the usual error correction to factor values: Just re-run the experiment as many time as needed, with the errors producing a new result each time, until you hit no the result you need. So you're using your "quantum computer" as a random number generator that eventually hits the correct result by chance.

> This is a depressing thought to consider in (linear) middle age, but it is hard to escape the feeling that it is essentially true. Childhood memories have an intensity and a vibrancy that it is difficult for the rest of life to match.

This is just not my experience at all. I had a great childhood, but ask me about the most vibrant moments, and very few of them came before I was 18. The births of my children, my wedding, meeting my wife, lazy afternoons in college...
by rixed | 2026-01-01 11:08:04+00:00
Sure enough, if you model life experience as a 2d plot, you are going to have to simplify things quite a bit. Yes, time "felt" longer for a child (especially when the child has to wait or wants something yet to come, less so when it's time spent on video games), and children are particularly impatient compared to adults.

But is that experiencing life, though? How many strong memories from that "logarithmic first half" of my life do I have? Actually very few compared to what came later, and they are not particularly compelling either.

My guess is that the author just hit mid-life crisis after having spent one or two decades in an office. Boring mindless job is what makes life experience to plateau, not adulthood. If I think of the most accomplished persons that I know, who've done many things with their life, I can't imagine them saying that their childhood was half of their life. They would probably laugh at the idea.

Or maybe he hasn't reached that crisis yet, since he finds solace in the idea that his child is doing the living for him. Wait until the kids leave home, for the log to turn into a exponential panic.

This doesn’t look like a particularly charitable interpretation of my comment, although my interpretation of the article isn’t either, so it’s only fair.

And no, I am not looking for a personal fitness advice in scientific research anymore (too late for that), but am rather trying to see its applicability to others, as per my understanding of those others around me.

Most people in the developed world aren’t 22-year old males.
A significant part of the population is comprised of the elderly or middle-aged, a lot of those people have pre-existing injuries due to under- (too sedentary) and over-use (blue collar work, youth sports).
Approaching physical fitness in those groups has its its own set of requirements and limitations, and I believe that in many cases resistance training is a more safe and efficient choice.

Not saying that the youth and children are unimportant, but typically they are already well covered by the organized sports and pt classes in schools and universities, unlike the adults.

My opinion is that the study is both badly designed (likely in a way to make it easier to implement) and is not applicable to the majority of the population.

The graph is just to clearly convey the idea, not to give it any more connotation of rigor than the idea itself has. The idea has a long enough history and enough research behind it to be in psychology textbooks and be referenced on Wikipedia, but it seems to resonate for some people and not others. https://en.wikipedia.org/wiki/Time_perception#:~:text=Propor...

I built this just for fun to see how frustrating I could make a standard signup form. The username keyboard shuffles after every click, and the password field forces you to run a physics simulation (calculating friction and force) to type a single character. It's totally impractical but was so fun to build. Hope you get a laugh out of it!

I find opus 4.5 and gpt 5.2 mind blowing more often than I find them dumb as rocks. I don’t listen to or read any marketing material, I just use the tools. I couldn’t care less about what the promises are, what I have now available to me is fundamentally different from what I had in August and it changed completely how I work.

I was bored so I did the math and you are not correct. Even if you don't care about the people themselves, a normal citizen in an industrialized society like Israel has about 40 years of working life. Let's assume for simplicity that some rockets would hit children but others would hit retired people, on average hitting people when they're halfway through their career and would have 20 years of productive work left.

According to Wikipedia [1], Israel has an average GDP per capita of about 60 USD per hour worked, which at 40 hours per week, 50 weeks worked per year over 20 years comes to about 40000 hours of work and ~2.4 million USD of GDP generated. At an income tax of about 30% [2], that means an income for the state of about 800k USD equivalent. If the person dies due to rocket attack, the state would miss out on that. Iron dome interceptors are quite cheap compared to that and the laser intercepts should be an order of magnitude cheaper still.

This doesn't even take into account the sunk costs that industrialized nations incur by every citizen having to attend school for about the first two decades of their lives, mostly funded by the state. That represents a tremendous investment into human capital that would be lost if you let your citizens get shot up in preventable rocket attacks.

So no, human lives are not actually cheap when viewed through the lens of a country, even when completely excluding morals and only looking at it financially. They are in fact quite valuable.

> Ads are content too, you know?

I agree. Why there isn’t this technology implemented on film streaming, movie theaters, even games? I think ebooks should stop you reading every five minutes just to show ads. I’m sure it could be implemented in to PDF pretty easily.

Internet and all medias point is to make money for jesus christ, what are we, a charity? Why don’t book publishers put ads into printed books, they are goving away content for free!

What does "think" mean?

Why is that kind of thinking required to create novel works?

Randomness can create novelty.

Mistakes can be novel.

There are many ways to create novelty.

Also I think you might not know how LLMs are trained to code. Pre-training gives them some idea of the syntax etc but that only gets you to fancy autocomplete.

Modern LLMs are heavily trained using reinforcement data which is custom task the labs pay people to do (or by distilling another LLM which has had the process performed on it).

Fun memory and a bit of an internal photo (and a rare shot of PalmOS software from the inside): https://ibb.co/nsVrW0h1

Sears' jewelry was... definitely marked up. This is from a SNC (SEARS Network Communicator, just a fancy term for their Symbol PDTs) showing true cost on a "$1299" necklace. $1299 down to $324? What a steal! It still only cost Sears a hundred bucks.

I don't know how powerful. It will fit a half sheet. The door is a little less than a foot high and the interior obviously is smaller. I wasn't being "I made timing measurements" exact by saying "almost as fast" - think "almost as fast for my purposes". It takes about five-ten minutes to preheat and my old toaster oven took minutes, not tens of seconds. I don't remember how many. It's just a big enough improvement over a full height oven that we use it a lot more, and don't bother with a toaster oven.

You also can toast just about anything in it under the broiler.

Every assertion in this article is completely alien to me to the point that I can not even comprehend that people live like that, it seems untenable to life to me. A year did not feel like a fifth of my life when I was 5, I could not even comprehend a year in that sense and very much lived in the present. Now in my 40s I don't see a year as just another year and still don't think of it as one 45th of my life. When I was 5 I saw where I was, now I see how far I have come and how far I have to go; all that has really changed is that I have come to understand how the past and the future define the present instead of just accepting that this is what I am currently experiencing, I understand cause and effect, consequence.

Does this article seem accurate to your perception of life? It would explain some things regarding my interactions with most people if I am so completely missing something so fundemental about their existence.

Edit: Why does conveying my experience and desiring to understand the experience of others get a downvote? Genuinely curious.

Great documentation of the problem! The bypasses logged all stem from the same root problem: policy sandboxes give agents constraints to optimize against.

I’ve been exploring a different model: capture intent instead of blocking actions. Scripts run in a PyPy sandbox providing syscall interception so all commands and file writes get recorded. Human reviews the full diff before anything touches the real system.

No policies to bypass because there’s nothing to block! The agent does whatever it wants in the sandbox, you just see exactly what it wanted to mutate before approving.

As a natty bodybuilder for over 30 years for anyone aspiring towards fitness and starting at the gym my most important advice is

"Put the phone away and bust some ass"

I see way too many people (the great majority) completely sabotage their training by putting the weights down when it starts to get hard and get on their phone.

When the weights get hard is when the real set begins. If you don't do the hard reps you deny yourself the stimulus required for adapting to overcome the stress, I.e the growth.

In the early 2000’s there was a porn site that completely covered you screen with porn pop-ups when you visited it. The funny joke back then was to opened it on school computer so that the poor teachers had to close them one by one (boot the PC if they were more savvy).

Today you can just open any major news site without ad blockers and effect is almost the same. There’s no porn, but it’s almost worst with the crap they open on your browser without asking. No wonder people rather get their news from social media.

Sorry, I don't understand. You're comparing 2 things. For the 2nd thing, are you including the cost of later recapture or not?

If you're not including the cost of later recapture, then it's not a fair comparison.

If you are including the cost of later recapture, why is it cheaper to recapture later than to do so immediately?

My best and “longest” memories are from a two year period spent in the university when I had earned some money in internships and could live with few obligations.

This is also the happiest I’ve ever been.

Childhood is mostly blocked out (abusive parents, poverty), and adulthood is mostly work.

Maybe we just remember the periods when we’ve been happy. It would make sense evolutionarily.
