Are you at or over 40?

Anecdotally I feel I noticed a very fast ageing speed between 38 and 40. Suddenly got white hairs, feel more tired, more wrinkles, way harder to keep VO2max up (I run a lot), muscle sores after training suddenly lasting up to 3 days instead of 1, face looks older, etc.

I feel like that all happened real fast around this age.

I'm a big fan of Bret Deveraux and a long term subscriber, but this is mostly nit-picking.

The Roman armies didn't dress as uniformly as this? They did in contemporary depictions (Trajan's column) so this is only as much artistic license as real Roman artists would take, and for the same reason - it's more visually impressive.

A Roman army wouldn't have this mix of units, or at least, it would have them in different proportions? Well, this wasn't typical, but you fight with the army you have - maybe your light infantry took heavy losses in a previous battle but you were able to cobble together a load of extra archers.

The tactics weren't typically Roman - or maybe they were, but not in 180 AD, because that specific period happens to be well-documented? Mixing some patterns from different eras is again allowable artistic license, one of the things that makes this art rather than an exact reproduction of a specific battle. And also, a good general adapts to the conditions: he had more archers than typical, so needed a different battle plan.

Comparing the weaponry anachronisms to having tanks at the Battle of Gettysburg is unfair: the American Civil War lasted 5 years, while Roman campaigns in Western Europe (Gaul and Germania) lasted at least a few centuries. It's closer to having an ironclad show up at Fort Sumter and complaining that design wouldn't exist until a year later.

The title literally says it's nitpicking, so I'm fine with that. But the introduction oversells it a bit more: "such a deceptive historical mess", etc. Like I said, big fan, but I was expecting inconsistencies more on the scale of "they seem to have marched 30,000 troops 100 miles in two days to relieve Minas Tirith, with no sign of any logistics to supply them".

I built EffiMail (https://your-domain.com) to solve a problem I faced: finding quality email productivity resources in multiple languages. What it does: Comprehensive guides on email management, privacy, and productivity Free tools: template generator, spam checker, subject line analyzer, read-time calculator Available in 6 languages (EN, ZH, JA, DE, ES, FR) Mobile-optimized with fast search and categorization Tech stack: Next.js 15 with App Router Static generation for performance i18n with next-intl Tailwind CSS for responsive design MDX for content management Why I built it: Most email productivity content is English-only, limiting accessibility for global teams. I wanted to create a comprehensive resource that works across languages and cultures. The trickiest part was handling MDX content localization while maintaining SEO performance. I ended up with a file-based approach that generates static pages for each locale. Looking for feedback on: Performance and mobile UX Translation quality (used mix of professional and AI translation) Missing features or content gaps Technical architecture suggestions Happy to answer questions about the implementation or discuss email productivity challenges you've faced.
Strategy or Just a Dream?
by KangrooJack | 2025-06-27 06:27:08+00:00
n general, my current strategy is focused on increasing initial capital. Here's how I'm approaching it:

I'm working in the mining industry in Australia, where even entry-level positions start at around AUD 2,000 per week. On a personal level, I hold tax residency in Paraguay. As for the business structure, I'm still deciding between setting up a Georgian LTD or an Estonian OU. If I find that a Belize-based company offers more credibility in Asian or European markets, I might go in that direction instead.

The estimated cost to set everything up—both personal and operational—is around USD 10,000. Getting fiscal residency in Paraguay has become much simpler since 2022. Today, you can do it through a specialized agency for around USD 4,000. They also provide a temporary residential address, which is a requirement for filing the paperwork. That part was a bit of a hurdle for me, since I recently moved to Australia. Doing it independently would take around eight months, and you’d still need to spend at least 3–4 days in Paraguay to find and rent a one-bedroom apartment.

Plan A Use my mining salary to invest in stocks or equity ETFs through a company structure, following a dollar-cost averaging strategy and taking advantage of compound interest. The focus is on choosing accumulating funds—those that reinvest profits—rather than distributing ones. The goal isn’t capital gains, at least not primarily, but rather to build up financial assets that can be used as collateral for loans and mortgages with banks or financial institutions.

Plan B Once I have collateral, I’ll use it to secure financing and purchase physical assets—real estate or high-value goods—with a practical, grounded approach. Step-by-step:

Buy a property Rent it out Initially focus on student housing for consistent demand Later move upmarket and target more specialized rental niches For example, in Albania, you can build something quite appealing with around EUR 110,000—especially if you’ve got a good eye for design.

Assuming the mining income remains stable (which is the foundation of the entire plan), I can take on multiple loans as long as I manage risk properly and maintain solid debt servicing capacity. You only need one property to get started and build experience. Two means you're getting serious. By the time you have three, you're no longer a beginner.

In my case—since I’d be renting the properties—the key is to ensure that rental income covers the debt within a clearly defined and pre-calculated time frame. That creates a self-financing system.

I’m not stressed about any of this. The real challenge is just the initial planning and structuring. As for unexpected events, I’m ready to handle them as they come.

Anyone interested in discussing this? Or have any tips on where to connect with people who have a similar mindset and ambition?

Sometimes I wish we could have kept XML alive alongside JSON.. I miss the comments, CDATA etc, especially when you have to serialize complex state. I know there are alternatives to JSON like YAML but I felt XML was better than YAML. We adopted JSON for its simplicity but tried to retrofit schema and other things that made XML complex. Like we kind of reinvented JSON Schema, and ended up like what XSD did decades ago and still lacking a good alternative to XSLT..

Isn't reading more like pattern recognition than parsing letter-for-letter? It seems to work like that for me. There's also the somewhat famous text where each word's letters are jumbled and people can still read it fluently. Maybe that's not the case for everyone, though, and people have different ways of making sense of written text.

Edit: Quick search turned up this article about the jumbled-word phenomenon, containing the example text at the top: https://observer.com/2017/03/chunking-typoglycemia-brain-con...

Been running sans shoes for 12 years or so, (early 40s). Before that, I started with Vibram FFs for a year. Can't for the life of me, ever imagine wanting to run with shoes on, again.

Seems apparent to me that shoes vastly alter the mechanics of a step. Just try sprinting at full speed for 20 meters or so, maybe indoors or something, if the pavement is intimidating. You might notice it feels very different. Much easier on the joints.

I say sprint because I imagine that would reinforce the instinct to ball-strike right off the bat. At least it was that way for me.

All that said, apparently some people still heel-strike without shoes and have to unlearn doing so. Also, trying to force ball-strikes with raised-heel shoes, when I was in my mid 20s, gave me terrible shin pain.

I also found the lack of a jolt from ball-striking, makes for easier breathing.

It may be intimidating at first, there are lots of little foot/ankle muscles that take time to get built, not to mention calluses that are like pads, but it certainly feels easier on the joints.

FWIW, I've had a bum knee ever since being pushed to the ground in gr4 so the fact it's no worse for wear should count for something. Of course my word alone means nothing though. Maybe take Harvard's.

https://scholar.harvard.edu/files/dlieberman/files/2012c.pdf

Anyway, I wonder if the running-knee-scare from yesteryear was because of a difference in shoe design.

Edited to add:

Oh yeah, I also want to add that barefoot running makes a MASSIVE difference in preventing ankle-roll injuries. For some reason I got really prone to rolling in my early/mid 20s or so. After running barefoot, it pretty much stopped outright.

The one or two times I did ankle-roll, (YAY work boots), I just shrugged it off and continued on, feeling nothing about 20 min later. This vs getting all swollen and not being able to walk for a week.

I'm pretty sure I've never rolled without shoes on. It's another one of those things that kind of seems evident. That is, that the mechanics of shoes hinder your ability to prevent rolling.

With shoes, you kind of lose the ability to deliberately pronate the ankle/heel, to micro-adjust balance, while keeping the ball and toes firmly planted to the ground. It seems to me, this is because the shoe heels are flat where our own heels are rounded. Also shoes are usually pretty stiff while feet can twist a little bit.

I would gladly take easier on our hardware, bandwidth and planet even if a bit harder on the developers' brains. (as a developer).

I wish we recognized that we need apps to be lean.

I think you are right, and I dislike React for this.

> The radiators are much smaller than the solar arrays.

Modern solar panels are way more efficient than the ancient ones in ISS, at least 10x. The cooling radiators are smaller than solar panels because they are stacked and therefore effectively 5x efficient.

Unless there are at least 2x performance improvements on the cooling system, the cooling system would have to be larger than solar panels in a modern deployment.

> Matrix isn’t perfect but it has only improved in the 5 years I’ve been using it.

I'd very much like to disagree.

From the top of my head, in the past few years of using Element Web:

- Notification center is now gone.

- Room search is now only limited to official Matrix rooms.

- At peak it consumes ~2.2 GB of RAM.

- UI feels more sluggish by the day.

- Loading it now takes ~10 minutes.

- Using it as an IRC bouncer (to Libera) is now gone, which was what initially attracted me in the first place.

And I don't even use the voice / call functionality of Element Web.

I somewhat understand the reasoning behind the decisions, but I feel like they should have improved the UX first before working on the protocol itself.

Maybe for a big llm, but if they add some gpu cores and added a magnitude or 2 more unified memory to their i devices, or shoehorned m socs into high tier iDevices (especially as their lithography process advances), image generation becomes more viable, no? Also, I thought I read somewhere that apple wanted to infer simpler queries locally and switch to datacenter inference when the request was more complicated.

If they approach things this way, and transistor progress continues linearly (relative to the last few years) maybe they can make their first devices that can meet these goals in… 2-3 years?

There are use cases where even low accuracy could be useful. I can't predict future products, but here are two that are already in place today:

- On the keyboard on iphones some sort of tiny language model suggest what it thinks are the most likely follow up words when writing. You only have to pick a suggested next word if it matches what you were planning on typing.

- Speculative decoding is a technique which utilized smaller models to speed up the inference for bigger models.

I'm sure smart people will invent other future use cases too.

Whoa, I just realized how much Zope’s page templates were basically XSLT that looked slightly different.

This gives me new appreciation for how powerful XSLT is, and how glad I am that I can use almost anything else to get the same end results. Give me Jinja or Mustache any day. Just plain old s-exprs for that matter. Just please don’t ever make me write XML with XML again.

> Doing this across different Linux distributions is inherently prone to failure.

Sure if you just take binaries from one distro that link with libraries on that distro and try and run it on a different one... But that's not what we're doing. All of our TCL modules are either portable binaries (e.g. commercial software) or compiled from source.

> Honestly, it sounds like you just don't understand these systems and how they work.

I do, but well done for being patronising.

> TCL modules aren't better than containers,

They are better for our use case.

> this is like comparing apples and organgutans.

If apples and orangutans were potential solutions to a single problem why couldn't you compare them?

Yes they did, and published it all.

Sometimes I can't believe how low discussions on HN can fall. Did really nobody in this thread bother to check this? Are we fine disparaging research solely based on the fact that they used a method that gives bad results with bad inputs (which doesn't?) and their incentives could be misaligned (whose aren't?)?

If there are well justified concerns about the method or data then by all means let's talk about it, but please let's all try to keep low effort anti intellectual conspiracy theories away from here.

> Others have tried to cook like the Neanderthals, concluding that flint flakes were surprisingly effective for butchering birds, and that roasting the birds damages the bones to such an extent that it's unlikely they would be preserved in the archaeological record.

I found this statement a bit alarming, as flint flakes being quite effective in butchering is quite well known — anyone who has practiced or studied “primitive living” ( that term doesn’t feel right…) would know.

However, that was not an explicit conclusion in the referenced paper, just by arstechnica. Not even a gripe, though, very interesting article!

> people also stop moving (exercising) significantly in their forties

Also likely that people who never experienced the negative outcomes of a sedentary or unhealthy life style start doing so due to the biomolecular changes. Drinking more likely to hurt your liver, soda more likely to cause diabetes, smoking more likely to cause cavities despite having done all that for 20 years without visible problems.

> but languished where it shined, as a markup language with an amazing transformation capability in XSLT

I choose to look at this a little differently.

An XML application using XSLT is so much better (faster load times, faster to write, easier to make correct) than a JavaScript application with a JSON api, that XML is basically a secret weapon.

I only care enough that it stays in browsers, but otherwise I'd prefer nobody know about it because it means less competition on things that matter (faster load times, faster to write, fewer bugs, etc). And I've got a half-baked JavaScript-based "renderer" I can finish in case some Google VP asshat goes looking for things to delete...

My mind jumped here too.

From the article:

>Subcultures were the main creative cultural force from roughly 1975 to 2000, when they stopped working. Why?

>One reason—among several—is that as soon as subcultures start getting really interesting, they get invaded by muggles, who ruin them.

>The muggles who invade and ruin subcultures come in two distinct flavors, mops and sociopaths, playing very different roles.

I'm 38. We had three kids over a period of 8 years. Looking at old pictures I seemingly held on for a long while, until something hit me at 35-36?!

It's like there's two versions of me now, the one who was somehow moderately fit by biochemical decree, with a healthy amount of flesh to his face, voluminous dark blonde hair and a pleasant complexion...

... And the grey haired, weathered, lined, dessicated mummy I see in the mirror. I love my kids dearly but the constant caring really takes something out of you. That and the whole getting older thing in TFA.

I keep telling myself I'll get a gym membership soon to reclaim some of my dignity.

"I think this is the quickest way of clearing my overdraft"

That statement from Michael Eavis (founder of the festival) kind of hits home with a recent story from The Independent in how bands are settling for less, or even paying to play at the festival - as an investment. Being shown on the BBC as part of their coverage can make or break the experience (and their economy).

Sounds like something someone < 40 would say. To anyone over, I feel like this study is pretty obvious. I'm in my early 40's and whatever change this is, has been discussed multiple times with my peers, active lifestyle or not, wealth or not, married or not, physical career or not. Everything starts to feel a little harder, whether it's exercise, problem solving, memory, sleep, sex drive, appetite, fuckin everything. Things change in your late 30s, for sure.

All young people think they are special and age is just a number. The rest of the population knows that isn't true. Spare me your weight lifting 80 year old, or "my grandpa worked the farm til he was 90" stuff, we all know those are extreme outliers.

Not really. The root reason behind Go's fast compilation is that it was specifically designed to compile fast. The implementation details are just a natural consequence of that design decision.

Since fast compilation was a goal, every part of the design was looked at through a rough "can this be a horrible bottleneck?", and discarded if so. For example, the import (package) system was designed to avoid the horrible, inefficient mess of C++. It's obvious that you never want to compile the same package more than once and that you need to support parallel package compilation. These may be blindingly obvious, but if you don't think about compilation speed at design time, you'll get this wrong and will never be able to fix it.

As far as optimizations vs compile speed goes, it's just a simple case of diminishing returns. Since Rust has maximum possible perfomance as a goal, it's forced to go well into the diminishing returns territory, sacrificing a ton of compile speed for minor performance improvements. Go has far more modest performance goals, so it can get 80% of the possible performance for only 20% of the compile cost. Rust can't afford to relax its stance because it's competing with languages like C++, and to some extent C, that are willing to go to any length to squeeze out an extra 1% of perfomance.

That’s an interesting point, I do often hear about being near a rail line as being a benefit for property values, but you don’t usually hear the same thing about being near an airport. Although this might partially be because a rail line is something people would use more often than an airport.

I don’t have much of a personal opinion on this. I just thought it was interesting. You’d think this train with a fixed route, tons of seating, traveling multiple times per day, would be cheaper than a plane, but somehow it isn’t.

The pollution and noise pollution is an interesting point, that could probably be improved somewhat for air travel while keeping the benefits, if electric planes could be developed. I was in India at one point and the noise of just being anywhere near roads was terrible day and night, it wasn’t even necessary people just love to honk there. There actually was a kind of luxury hotel city (Aerocity Delhi) near the airport there, I guess if they’re already used to that much noise being near an airport can be valuable.

There is some advantage for cars and planes in that you don’t need to develop the whole land between the two points you’re interested in traveling between as much as you do for rail, maybe that’s where the price difference is coming from.

And instead incurred the burden of imunnosupressive drugs. It may be a good trade, but this isn't a zero consequence thing.

The treatment injects foreign genes, modified pancreas insulin producing cells/genetics. Without immune suppression they're engulphed. But they did, once immune reaction was suppressed, they did embed, and survive.

> fully open source including the server side

But, and maybe I'm stating the obvious but it is a critical difference, open source is nice but much inferior to open interoperable standards.

Signal-the-company does not allow any clients other than their proprietary compiled client (I believe they sort of tolerate some, but not supported). So while in theory I could use the open source software to run my parallel signal-protocol network, it won't interoperate with the one run by Signal-the-company which is where most people are. So, not actually useful.

Contrast this with email which is an open standard. I can run any SMTP server I like and any MUA I like (or even write my own for one or both), and interoperate with the whole universe of people who use email.
