It is easy to understand the impact this will be in people’s lives.

I think within no time it will be modded with motors, maybe salvaged from broken electrical appliances and it will come full circle.


You’d need electricity for that and a lot of places don’t have it.

You'd be surprised at the places that have electricity, like houses in middle of nowhere, central asia. One of the challenges with engineering technology for the global south is that poverty is wildly different for different people. I met a professor working on flatpack windmills to pump water/electricity. The major challenges he kept seeing in the the Andes weren't the sorts of longevity/efficiency/logistics issues we usually solve with standard engineering, but how the products interacted with local politics and society.

Solar maybe

To add to AlotOfReading's point, many places have some electricity, just utterly unreliable.

It might be down a few hours every day, or completely cut for days after storms or infra degradation, or the current fluctuate too much for delicate electronics. Many places could also get hold of a gasoline generator.

These kind of variations could require more thinking on the design, but being able to use electricity when available and hand power when needed would be the best.

Ideally the people on the ground thinking about their specific issues and having open ways to adapt the machine for it opens the door for many kind of evolutions.


That is a much better article.

It is not a wall, but rather a “network of submerged stone structures”.


> There is a set of languages which are essentially required to be available on any viable system. At present, these are probably C, C++, Perl, Python, Java, and Bash

Java, really? I don’t think Java has been essential for a long time.

Is Perl still critical?


From my experience of building LFS it appears to be needed to built as part of the tool chain.

It's extremely hard to build any unixly userspace without perl dependencies.

I really do wonder who (as in "which packages") still depends on perl. Surely it can't be that many?

Edit:

On my (Arch) system removing perl requires removing: auto{conf,make}, git, llvm, glibmm, among others.


excuse the late reply, but check what requires perl as a makedep

critical at build time, not runtime

That is really interesting. Pity half of them use a "eval(unescape(escape(x)).replace(/u../g,'')))" with a compressor and decoder function.

> dates back to the late 1890s and will be replaced with a modern, more durable, metal trough.

I think any infrastructure that has lasted over 130 years is already quite durable.


It's wood, I'm sure the MBTA has a workshop that can build replacement parts.

Odds are the replacement is going to be some custom metal machined overseas and will be basically irreplaceable due to cost and skill issues.


The MBTA has a quite capable metal shop that's been making replacement parts for the 1960s vintage subway cars for quite a while.

Right but it will be something they can't work with. Like some custom magnesium-aluminum metal that has to be cast and can't be machined with normal tools.

And being the MBTA, it will be installed in the wrong size and have to be replaced in a couple of months.

My bet is on that there will be some kind of interaction of the metal catenary in the environment and maybe causing friction in the cables and shorts, which no one thought of since 1890 when they chose wood due for its insulating properties.

Then they will have to replace the metal with some fancy plastic one, because you can’t just admit the wood was better after all, but the plastic will also be unsuitable and degrade quickly which will ultimately end up with going back to wood in another 10 years. But that wood will then only last a fraction of the original wood, because we do not have old growth wood anymore and all the pine plantation wood won’t last a similar 130+ years.

So after about $3 billion dollars in costs and another $5 billion in economic and lifestyle impact after 20 years, they’ll declare it all a wonderful success, even though the wooden catenaries will live on as art or interior decor for another 200 years.

If we’re lucky, the death toll will even be low.


I foresee a "oh we can't replace the plastic one it with wood now because that would be a new material and we don't have data to prove it conforms with some rule we made up so the only solution is to pay some engineering firm who knows people on beacon hill a ton of money to say that pine is fine" situation before they go back to wood.

And as bad as the MBTA is... Keolis is worse (arguably).


Har, har, har, Buy Murican, amirite?

I encourage anybody who gets the opportunity to ride the green line. It's cool that they managed to build it in a time before tunnel boring machines (by literally digging a huge, long pit, building the track, then covering it with a roof and dirt again). Just wear noise cancelling headphones or something cuz those trains screech

Cut and cover is still the cheapest way to build subways, but is less often used nowadays because of the surface disruption.

Long before tunnel boring machines existed we needed to develop methods to dig under rivers. Brunel invented the tunnelling shield for digging under the Thames in 1825 and later a more refined version was used to dig the first deep-level tube line which opened in 1890.

THIS kind of comment is what makes HN gold!

TIL...


It's probably not the same wood since 1890. Requires more repairs and replacements.

I think there's a good chance it is. Not out in the sun, not in contact with ground/moisture, pretty consistent temperature. Wood can last a very long time under those conditions.

It could be. A lot of wood has been around for longer than that. Wood is easier to damage so I expect some has been replaced over the years, but there is no reason to think it wouldn't last in that application.

Yeah, I watch mine exploration videos and it's shocking how well wood in a dry and stable environment will last.

I wouldn't exactly call the environment on the green line as dry, especially in the summers.

The city of Venice is literally built upon timbers driven into the seafloor.

That haven't ever been replaced.


Maybe the chemicals they've used to treat the wood were so hardcore

Once again, promo-driven culture rears its ugly head.

> I was stopped by police while taking a walk and shouted at and treated like a criminal when walking in to a Wendy's drive through

I live in a very bike friendly country, so culturally closer to Europe in terms of transport, but if you walked into a drive through you may well be stopped by police.

Drive throughs have long since stopped serving pedestrians.

Generally anyone trying this is inebriated.


As a kid I used to skate (roller blade?) through our local MC Donalds drive through, did give the personnel a little chuckle every time we did it.

I worked at the local McD as a teenager and it was always funny to see a horse ordering something (the camera does not pick up the rider). Ours was near the end of a trail often used by people on horseback.

And since horse riders are legally equivalent to vehicles it's pretty much a "fine as long as you don't shit in the driveway" situation.


The “cars only in the drive thru” was mainly driven by insurance requirements; cars aren’t expecting pedestrians there.

>Drive throughs have long since stopped serving pedestrians.

That's a social class and location based. The average overpaid techie on HN who lives in the kind of place where all the houses are a million bucks and everyone buys their trophy wife a 4Runner because that's what you need for one kid then yeah, the drive through won't serve you as a walk up.

The Popeyes in Camden NJ don't care if you ride an elephant through the drive through.


>Drive throughs have long since stopped serving pedestrians.

You quoted me but I was commenting on my country, an egalitarian country in the Pacific.


> Anthropic isn’t exactly jumping up and down telling everyone how awesome it is, which tells you everything you need to know.

You can’t really read into that. They are unlikely to let their competitors know if they have a slight performance/$ edge by going with AWS tech.


With GCP announcing they built Gemini 3 on TPUs the opposite is true. Anthropic is under pressure to show they don’t need expensive GPUs. They’d be catching up at this point, not leaking some secret sauce. No reason for them to not boast on stage today unless there’s nothing to boast about.

Yes, but Google benefit from people using their TPUs, while Anthropic gains nothing unless AWS throws money at them for saying it.

This.

Anthropic is not going to interrupt their competitors if their competitors don't want to use trainium. Neither would you, I, nor anyone else. The only potential is downside. There's no upside potential for them at all in doing so.

From Anthropic's perspective, if the rest of us can't figure out how to make trainium work? Good.

Amazon will fix the difficulty problem with time, but that's time Anthropic can use to press their advantages and entrench themselves in the market.


I am not sure, I would imagine enthusiastic quotes will lead to huge discounts and in that scale that matters

Striking a deal with a competitor (AZURE) does though.

> The secondary market hurts their sales for new sets, or so they believe.

I think the secondary market drives sales. People need to believe that the overpriced sets they are purchasing, never open, and stash in the attic will make them a fortune on the secondary market one day.


Can you tell me about "Simtel"? I have never used a BBS but from looking at that ISO it was a collection of software downloaded from BBS' ?


FTP server, not BBS. You had to be on the Internet to access it.

https://en.wikipedia.org/wiki/Simtel

It was called SIMTEL20 for a while because it was hosted on a PDP-10 mainframe running the TOPS-20 operating system, but apparently it was hosted on a PDP-10 running ITS first:

> The archive was hosted initially on the MIT-MC PDP-10 running the Incompatible Timesharing System,[1] then TOPS-20, then FreeBSD servers


That is an interesting piece of internet history, thank you for sharing.


> Stick a microphone and camera outside on a robot and you can get unlimited data of perfect quality (because it by definition is the real world, not synthetic).

Be careful with mistaking data for information.

You are getting a digital (maybe lossy compressed) samples of photons and sound waves. It is not unlimited, a camera pointed at a building at night is going to have very little new information from second to second. A microphone outside is going to have very little new information second to second unless something audible is happening close by.

You can max out your storage capacity by adding twenty ML high megapixel cameras recording frames as tiff file but gain little new useful information for every camera you add.
