I wonder how much human health is impacted by these leaky pipes.

I would like to see a city where pipes are guaranteed leak free, for example by making them double walled with high pressure air in the outer layer, and then seeing if disease levels in the city are lower.

We already have this data in a way, from cities where there is no running water and people rely on bottled water for drinking and washing.

Not to mention being a ruminant with multiple stomach compartments and a long gut.

Aromasin · 15 days ago

Humans are quite capable of digesting a diet rich in legumes just like all our other close relatives in the great ape kingdom. They subsist on a 85-99% plant based diet, primarily of fruits, nuts, and seeds. We have clearly adapted to eat more meat as our bodies changed to master running and throwing for hunting, but we are still a variant of great apes at the end of the day.

> Legume improves bovine digestion and reduces methane emissions.

For people too---but you have to pass it through a cow first and eat it in the form of beef. Otherwise ...

Aromasin · 16 days ago

Gut biome is important for legume consumption. The first few months I went to a plant based diet my digestion was hell. At some point I reached a turning point though, and my gut health became even better than before. My flatulence was so much worse when I was eating meat regularly - often room clearing.

I haven't heard anyone mention this rule, which I think is useful:

Cars, dogs, and water.

These are the big three common things that children interact with regularly that can, and will, cause irreparable harm or death with functionally no warning and virtually instantaneously. Kids also don't have the experience or the intuition to figure out if a situation is dangerous; cars move too fast, dogs are too hard to read, and water danger is hard to grasp even for adults (the number of people, including grown adults, I've seen panic and had to get pulled out after gleefully jumping into water where it turns out they can't reliably touch the bottom is fairly high).

The first two require some strictness (i.e. being very clear about rules like never going near a road without an adult, and never hitting a dog or pulling it's ears), but water basically requires regular swimming lessons from qualified instructors. It's something I wish happened earlier, and that more families had easy access to.

I surf a lot, and I've lost count of the amount of times I've had to save people from a riptide. They're always completely exhausted, barely keeping head above water, and minutes from getting pulled out to sea with no energy left to swim around the rip and back to shore. I pulled out a couple on deaths door on their honeymoon just a couple weeks ago - that could have crippled their families. It's frustrating the lack of awareness people have around the sea. Unless you know the shore you're swimming on intimately, or the sea is flat with no swell, there's no guarantee you'll be able to fight the sea if you're further out than up to your waist in water.

I've looked at this question in Rugby Union. In my opinion. The travel issue is the main factor for home advantage. Travelling is physically and mentally tiring. If you can ease the travel methods. Where you either cultivate a team environment where people will be at ease being away from home / home base. Or travel earlier and in better form. Then you will end up with better away results.

Aromasin · a month ago

In Union, many of the popular leagues are international clubs level. For most of their history, they were split into Southern and Northern hemisphere leagues. Recently that shifted, and the South African teams joined the United Rugby Championship which is European (Ireland, Italy, Scotland, Wales, and before Top 14 became preferred, France). This was because, despite the historical significance, the time zone difference between the South African and Australia/New Zealand teams were too severe. Now South Africa is in the United Champinoship, they only play in a +/-2 hour difference in terms of time zone.

Shotengai arcades have been dead or dying since the 1990s if not earlier, and it's not gentrification that's killing them, it's lack of demand. For daily needs, in Japan as everywhere else in the world, one-stop shopping spots like supermarkets and convenience stores win out over visiting lots of specialty retailers that can't compete on price.

I often watch travel vloggers visit these places and you can't help but notice that all the vendors are also in their 70s or older, and they run them on their own. With no generational hand-over these places are doomed not matter how succesful or not they might be.

Maybe I'm just jaded and demanding, but:

1) As others mentioned, two GbE interfaces seems really limited for a 2025 project. Modern FPGAs can support 100GbE and up - I don't necessarily expect that on a hobbyist-level project, of course, but 1GbE is well behind the curve.

2) There don't appear to be any hardware design files (e.g. schematics, PCB layouts) in the Git repository. In fact, the only mention of the current FPGA is a single text file stating that "Cyclone 10 GX port in progress"...

3) There's basically zero open source support for Intel/Altera FPGAs. Yes, you can open-source your HDL, but the vendor tools are all closed-source and there's no alternatives.

Aromasin · 2 months ago

Agreed. They are using an Cyclone 10 GX - that's over $250 for a part from 2017...

If the restriction is wanting low price to suite the FPGAs open-source low-budget market, they'd be better off using a Lattice Certus-NX or something. 5Gbps SERDES on that for ~$40, or better yet a CertusPro-NX with 10Gbps SERDES for ~$70. Altera and Xilinx are just throwing away the sub-100K-LUT market to Lattice at this point, yet people are still building systems out using these expensive, antiquated parts. That's shelf pricing too - go through a distributor and it'd be 50% of that price!

I've had some fun learning how to implement various bits and pieces of networking on FPGAs as a hobby for a while, and while boards like this that focus on gigabit network are fine, the fact is that there are a lot of FPGA boards with gigabit and 100Mbps interfaces. What there are not enough of are low cost boards that can do 2.5Gbps, 5Gbps and 10Gbps. Lattice has some very affordable FPGAs with 5Gbps SERDES, and their newer 10Gbps capable chips remain extremely affordable.

One of the things I would absolutely love to have are a couple of FPGAs boards in SFP and QSFP form factors. Why might you ask? Because it would be seriously useful to have a PPPoE / L2TP data plane to plug into the port of a 100Gbps capable switch for use in the network edge. Modern ethernet switches have plenty of Layer 3 networking capabilities, but most switch vendors fail to expose any functionality for these protocols even though the underlying ASICs often enough have the capability to handle them. Sure, you'll never see these protocols in a cloud data center, but plenty of incumbent telecoms make use of them in their FTTP networks due to the legacy of xDSL deployments and the need to support wholesale access to those networks. Sadly, developing such a board is beyond my hobbyist electronics capabilities, but I'd have no problem bashing a bunch of Verilog / VHDL into shape to make it work in fairly short order... I just hope it uses an FPGA like the Polarfire for which the SERDES are about 100x easier to use than the gawd awful Xilinx 7 series (KC705, I'm glaring at you for eating weeks of my hobbyist life to that bring up).

Aromasin · 2 months ago

You can absolutely do this using something like a CertusProNX from Lattice (I much prefer it to the Polarfire), mounting an SFP/SFP+ cage onto the FMC connector of the board, and wire their transceiver lanes to the FPGA SERDES pins. HiTech Global has a 4-port SFP/SFP+ FMC module. I believe there are also QSFP mezzanine cards but I haven't looked much into that. ISI or Trenz probably make something.

At volume, $550 for 600k LUTs is outrageously high and much more than what you’d pay Xilinx or Altera.

Aromasin · 2 months ago

Absolutely, but I quoted shelf price. Volume pricing can be anywhere between 30-80% less than that. Agilex 5 equivalent is ~$900 and much the same for the Ultrascale+ equivalent, so Lattice is the most competitive on cost.
