Something I’ve been thinking about is whether the current technological landscape, through positive and negative pressures, can enable a revival of small-scale production. Basically, making more of what you consume at home, in your neighborhood, etc. I think “human scale” technologies can help mitigate some of the more nightmarish horizons of the technological society we inhabit, though, obviously, neither completely…

I'm a physician and I've thought a lot about this in the context of the US healthcare system. Step foot in a hospital and the first thing you notice is that everything is single-use, thousand-dollar widgets. I've been into the idea of open-source medical hardware and software for a while. The unfortunate reality, however, is that the obscene cost of getting FDA approval for even the simplest medical device makes thes…

Some larger hospitals already have this, or had something like this. I know personally of one that had an in-house engineering team and it was slowly dismantled in a process of outsourcing, until the remainder of the team resigned as a group. It caused a certain amount of chaos.

EHR is sort of similar. To me, the roll-out of that was a disaster, and pushed what was in-house in most cases to being managed by EPIC and other EHRs out of the hospital. The mandates were a big mistake in my opinion, as it forced hospitals to scramble to use something being offered by outsiders, instead of collaborating to produce something open-source, or growing EHRs more organically from within the organization.

I personally blame the rise of hostageware in hospital settings partially on this trend.

My broader point is that although I think there's a lot of potential with open source hardware, software, and things like 3D printers, prevailing economic forces are pushing in the opposite direction. Consolidation and mergers, streamlining everything that doesn't contribute to increasingly dense profits as you go up the administrative chain. In this schema, better to outsource everything you can to trim costs. I don't agree with it, as I think it leads to a lot of hidden costs and hidden but lost benefits, but that's the idea.

Unfortunately, the combination of overregulation and profit-driven hierarchical management is creating pressures against in-house, from the bottom up creation of goods and medical services. The talent is there, it's just pushed out from the top.

Sometimes I feel like healthcare and the biomedical area is today driven more by the interests of profiteers than patients/clients/customers.

Probably nothing. I think we peaked in early 2000s and now we're floating on a plateau. I don't think progress will be restored during my lifetime unless we first meet a shared catastrophe on the level of WW2.

In a weird bleak way I was hoping that Covid would be a catalyst for the next big reset, in the way WW1 and WW2 were, but it would have needed to affect our daily lives greatly for at least 5 years for that to happen. It only managed to cripple us for 18 months, and for many it is life back to normal. Again we have used technology to preserve the status quo, and not for the betterment of the human race.

At least in OSH for Medical Devices, the limiting factor under current 21CFR regulations would probably be Manufacturing and the associated support operations. Design & Development is tedious but doable in an OSH/OSS fashion, and getting through 510k could probably be solved by people donating skills (and someone else donating cash). Don't quote me, but I don't think that the actual fees that the FDA charges to do a 510-k submission are not particularly high, it's just that the work that goes along with it is burdensome and people want to be paid. In an Open Source approach, this could largely go away as long as someone donates the fees.

That gives you a design that the FDA is happy with.

Now you have to build, distribute, service and support that device and no matter how you slice it, you're looking at substantial costs to comply with 21CFR across all these tasks. So this is where the creativity really has to come in: can we spread those costs across a "community" to make it worthwhile, or will we just end up right back at Square One with single use, $1,000 devices?

I don't think there's a path forward (at least in the US) without change to regulations.

Photonic computing and the return of Fortran. These are two separate things but to some degree they're both boosted by the rise of heterogeneous computing.

I'm curious about the Fortran aspect - I've never worked with it (though I've always been a little curious). Care to elaborate?

It's sad, but... nothing.

The things that I do find interesting are usually expensive, which crushes any interest. I hate my job and mostly see technology as torture due to it. Even if I want to work on an idea, I don't feel like staring at a screen after working my regular job.

Earlier quoted context omitted.

I didnt realize that people felt this way. In what way do you imagine personal computing would change if intel was broken up? I can't even imagine what vision you have in this regard.

If intel had been even just a little less rapacious, things like many alternative architectures might've existed for longer (Alpha was kewl!). I can't do justice to the examples of bad faith marketing they've indulged in, anti-competitive acquisitions of promising companies that then are buried, architecture choices made for marketing gains that saddle programmers with years of boneheaded bullshit, delightful tricks…

Am I wrong in thinking alternative architectures could make it harder to develop software, and a lot of boneheadedness is a result of backwards compatibility? We already have ASICs for very specific processing applications, so I'm not sure society is suffering a huge opportunity cost. That said; I'm not a computer engineer or architect, or even anything close. Also the 'oopsies slow paths' thing is actually business horse shit, and I have heard that rumor substantiated by quite a number of people.

I'm down for open source architectures, but our manufacturing technology is not ready to support DIY processors yet, even at low speeds. Solving the manufacturing process could go a long way to spurring competitive processor architectures.

I'm enthusiastic about block chain. Is it in a bubble? Yes, but so is virtually every speculative asset... Blockchain legitimately has potential to solve major social problems equitably, for example, online representative voting with open source software, anonymity, verifiability, higher efficiency and powered by the people. Otherwise, I'm getting pretty stoked about computer vision techniques. If I had more time I w…

> Blockchain legitimately has potential to solve major social problems Blockchain was cool and novel, but the hype should be over already. We’re nearing 15 years of blockchain tech and it is still not magic powder that solves society’s problems.

I think its made remarkable progress, especially now that Proof of History exists and Proof of Stake is widespread, most of the ground work is set for efficiently creating trust-less game theoretic environments. I think developing blockchain techs is a naturally slow process, since it take so much effort to test and start a network. If you are used to thinking of blockchain dev like normal software, you would be correct in thinking that blockchain is unimpressive, based on its velocity.

Its not a magic bullet for society's ills, but its going to be a game changer if people really want the games we play to be more equitable and impossible to hijack.

I am excited about dedicated servers. Yes, dedicated, not cloud servers in AWS or something like that. I am interested in running my own server for decades, but nowadays, since about 2 years, you get extremely powerful and reliable servers for already 40 bucks a month. That is amazing. The power you can deliver today compared to the costs reached a very good ratio. This was unthinkable 5-7 years ago and open a lot of…

The cloud is really just the centralized computing paradigm of the old days with a new coat of paint. This fascinates me because people seem to have forgotten that the reason personal computing was such an incredible thing is that it freed people from that old paradigm. I suspect that, over time, people will lean anew why it was that being freed of it was such a great thing.

Yeah, exactly this! I'm always telling people that "the cloud" is just taking us back to mainframes and dumb terminals. Especially now with things like Chromebooks existing.

The most offensive thing of all is that modern dumb terminals don't have keyboards anywhere near as good as the old days.

The race for breakeven fusion is heating up, and it's exciting to see. That old adage about reaching breakeven being 'always 30 years in the future' is actually, finally looking more like 5-10 years. Relevant projects, all tokamaks: The largest ever fusion reactor so far which is being built now -- ITER in France, then there's MIT/Commonwealth Fusion's SPARC (they just demoed a type 2 superconductor magnet that devel…

Sabine Hossenfelder recently explained why breakeven fission is much further away than the public generally believes [0]. Without spoiling her explanation, it boils down to how you measure "breakeven".

GNU Guix and reproducible builds. That software can be bitwise reproducible and explicitly declared feels like an exit ramp from the relatively brittle systems that are standard. It feels insane to me that only now these concepts are coming to fruition. Afaict, Guix and Nix invalidate the need for things like puppet, ansible, etc.
