My friend, I understand this experience is very real and painful to you, but to me and others who might be reading this message, you appear to be displaying signs of schizophrenia. I've read through this and other messages you've posted on HN, and I'm being reminded of the writings of Terry A Davis, another programmer who used to post on HN who believed he could speak to God through the operating system he was developing all by himself. I would encourage you to read up on Terry, and to consider seeking psychological help. I understand that may be difficult to contemplate, but Terry ended up dying by being struck by a train while walking on train tracks; he was either so out of his mind that he didn't see or hear the train coming, or he committed suicide. It would be tragic if a similar fate befell you.

Implemented properly, the idea is that you have a chain of certificates (rooted by the CPU vendor's public key) that can identify all the different bits of software that have executed on the machine, along with a ephemeral public key. The hardware guarantees that the associated private key can only be wielded by the software versions that the chain attested to. So when you initiate your TLS connection with this machine, you can validate the cert chain and understand exactly what software the machine is running, assuming that you trust the CPU vendor and all the versions of the software that were attested to.

"Silicon solar cells do not contain toxic compounds. "

This is absolutely untrue. The silicon is just the starting base, you still need to dope the cells, often with an arsenic compound (Indium-Gallium Arsenide, Gallium Arsenide, etc.)

In the EU and California, solar panels are exempt from RoHS requirements.

I used to manufacture solar panels for Sunspark Technology in California. You can't get the same kind of conductivity using tin bus ribbon without sacrificing usable cell area, as you need a wider, flat strip of tin, compared to lead. The newest "invisible bus bar" panels are using silver wire. These cells, when I worked there pre-COVID, were dumping ~11A at full light exposure. The inter-string bus bars were lead-coated copper, as were the string to junction box interconnect ribbons. 60/40 was used in the junction box. We manufactured panels for everyone, including Jinko, that behemoth of a solar corporation.

Solar panels very often have toxic stuff everywhere.
Remote attestation or not, "Software freedom" fighters should understand that things happen based on some user base need. Somebody needed this and they added it, whoever needs it doesn't care if they can't run linux on it. If the user cares about running anything else on the hardware, they will add a way to disable the feature. it is all about the user need.

if you are a secondary priority user on some hardware, the way to fix it is to focus on becoming important enough to be prioritized instead of fearing some technology will limit things.

I'd suggest maybe just the nature of organizations becoming more corrupt over time. When an org is younger more of its focus is still put towards the task it was originally created to perform, but the longer they exist the more bureaucracy and corruptness sets in, the most institutionalized they become, the more they put their effort into just spreading their influence and enriching themselves rather than performing their original task.

Sometimes at points in their history an org can reform itself and revert back to an earlier stage, but at this point I personally feel that most major institutions have been around long enough that they've effectively become corrupt beyond the point of reform, and just need to be replaced.
Not only does the author ignore the huge progress in conventional garbage collected languages like Java, he also dismisses GC as inherently flawed despite the fact that the common strategy of only having one heap per application has nothing to do with garbage collection. In Pony each actor has its own isolated heap which means the garbage collector will only interrupt a tiny portion of the program for a much shorter period of time. Hence the concept of a stop the world pause is orthogonal to whether you have a GC or not. One could build a stop the world pause into an RC system through cycle detection if desired.
And so isn't this basically the flaw in the whole idea? You can always emulate a TPM. You can always boot with a stock kernel and have the host patch the memory afterwards. Software can try to detect whether it's running in a VM, but the VM can lie. Last I heard, blocking VMs didn't go so well when nVidia tried it.

Am I wrong about the effectiveness of this? I'll readily admit I don't understand most of the underlying tech here.

These consumer facing apps always have the most barebone features (order from menu, earn/redeem loyalty points), yet they always seem to need a native app to deliver it instead of the mobile website.

Is it because customers are used to apps after a decade of "there's an app for that" marketing? Or is it because apps allow for always-on tracking that browsers don't allow?

On a website, the browswer will let you know each time the site is trying to track your location. In an app, you just need to give them permission once and they'll always use it.

For this reason, I use m.uber.com (if I have to use Uber at all).

Of course not. Things happen based on what investors and developers want. Users are very much secondary. They're a nuisance. If things did really happen based on some user-base need, would we have had Instagram or Facebook in their current form?

I also run Arch. `systemd-analyze critical-chain` shows that the longest Linux step is `systemd-udev-settle.service`. The UEFI step is longer still, and I don't have a classic bootloader, I use efistub.

My network is handled by NetworkManager, so I think it only comes up after I log in. I'm not quite sure what udev is waiting for, but since I don't boot up my computer often enough, it never bothered me enough to go hunting. But it's just surprising to see Windows come up quicker, on exactly the same hardware (dual boot on the same NVMe).

Different company, but Lam Research had a finance CEO, he had to 'resign' because he liked leading women on with career advancement promises more than running a critical infrastructure company.

> … assuming that you trust the CPU vendor and all the versions of the software that were attested to.

That’s a huge caveat.

You also cannot verify your trust is deserved, and that it will continue to be deserved, because such a system by its very nature must be opaque to untrusted parties (which means you).
Another alternative to silicon cells that is actively being researched is perovskites:

> Perovskite solar cells hold an advantage over traditional silicon solar cells in the simplicity of their processing and their tolerance to internal defects. Traditional silicon cells require expensive, multi-step processes, conducted at high temperatures (>1000 °C) under high vacuum in special cleanroom facilities. Meanwhile, the hybrid organic-inorganic perovskite material can be manufactured with simpler wet chemistry techniques in a traditional lab environment.

You already do have mandatory disclosure on shenanigans like that in the US. It's the boilerplate HIPAA agreement you sign when you first see a provider.

I hate Cloudflare with burning passion. Not only is it a US company that centralizes internet infrastructure around itself, it also terminates TLS for way too many websites and sees their cleartext traffic. It then actively meddles with said traffic and punishes you for something you have no control over (your IP address). It's a dystopian nightmare only second to online ads. But ads at least can be blocked — you have zero agency in case of Cloudflare.

Whenever I see the "one more step" crap, I just close that tab.

Cloudflare needs to stop existing, and it needs to do so yesterday.

Schottky barrier cells are a well established idea in photovoltaic research. Here's a 1975 report on an effort to develop low cost Schottky cells:

"Silicon Schottky photovoltaic diodes for solar energy conversion"

https://ntrs.nasa.gov/api/citations/19760005411/downloads/19...

Here's a very early (1953) review of photovoltaic cells that includes Schottky barrier cells:

"Photovoltaic Cells and Their Possible Use as Power Converters for Solar Energy"

https://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.52...

There are a couple of problems with the implications given by the quote

Schottky cells do not require a high-temperature phosphorus-diffusion step, which ordinarily creates the n-layer of the p-n junction in silicon today. This alone reduces the energy input into the solar cell production process by 35%.

Reducing the solar cell energy inputs by 35% is a clear win only if the cell output does not fall commensurately. A record 17% efficiency for a Schottky cell compares to over 24% record efficiency for PERC cells made with conventional high temperature phosphorus diffusion:

"Trina Solar claims record 24.5% efficiency for 210mm PERC cells"

https://www.pv-tech.org/trina-solar-claims-record-24-5-effic...

That means that the best Schottky cell generates about 69% as much energy as the best PERC cell while taking about 65% as much energy to manufacture. The Schottky cell generates about 7% more output energy per unit of input energy -- a pretty marginal improvement.

There is a more promising alternative to high temperature diffusion cells already in mass production: the heterojunction solar cell. It was originally commercialized by Sanyo (later acquired by Panasonic) but its patents have recently expired so several manufacturers now make heterojunction devices.

Major solar manufacturer Longi just set a cell efficiency record of 26.5% with a heterojunction design:

https://pv-magazine-usa.com/2022/06/24/longis-heterojunction...

Heterojunction cells are processed at low temperature because the delicate amorphous silicon layers cannot withstand high heat:

"Silicon heterojunction (SHJ) solar cells have typically a low process temperature limit (~250°C) because high-temperature annealing processes can degrade the passivation of the hydrogenated amorphous silicon (a-Si:H) due to the hydrogen effusion during the annealing."

(From https://www.intechopen.com/chapters/61900)

Given the combination of low temperature processing and high efficiency found in heterojunction cells, I am personally doubtful that the Schottky barrier cell can offer superior energy return on energy invested for solar power systems.

Can you even do paper prescriptions any more? I've only had digital ones my entire adult life.

Quick edit to answer my own question: In my home state paper prescriptions are only legal in a few situations (if it's for an animal, glasses, justifiable emergencies). However in some parts of the country they're still possible. Even if I had a choice, I prefer the convenience of sending the data digitally- once you actual fill the paper prescription CVS or whoever is still gonna be able to glean sensitive medical info, so you're just delaying the inevitable.

i diasagree with your comment on every level

Originally I expressed no opinion about national debt, I merely point out hypocracy of making demands of future generation, but acting angry and righteous when those generations make requests of us.

also I spesifically stated that I do not buy into ideology typically attached to 'small government'.

also the premise that the only way to deal with national debt is to have smaller government is wrong, we could have higher taxes or print money

Lastly the idea that smaller government is more efficient or cheaper is wrong too - industries where the government is the only buyer, like prisons, tend to do terribly when they are given to the private sector - it creates insentive for corruption and fraud and is actually harder to manage as a market than it is for a government to run them directly. In every meteic, from recisevism to in prison murder rate, private prisons do worse.
I don't know where you got the words "entertained", "fun things to do all the time", or "spoon fed" from. I didn't use any of those words and I think we actually agree that meaningful things doesn't equate to parties all the time.

When I say engaged and meaningful - I mean it in the purest sense of the words, whereas you seem to equate it to "unserious".

Back to concrete questions: Are business leaders and educators presenting problems in a way that people connect with and see the value of? Are they providing an environment that makes people want to work hard and makes them feel empowered to take on difficult challenges?

Take History education for example. I'd say the answer to the above questions are "no".

* Most students who take a History class in a typical American school don't see how memorizing dates for tests connects to anything meaningful in their life or understanding of the world.

* I'd say educators don't or can't spend much time or effort connecting the dots or presenting information in a way that inspires people to ask deeper questions.

Instead, the focus is on rote memorization in preparation for flawed standardized state tests which themselves serve as the basis for obtaining federal funding to run the school itself.

Not to mention teachers themselves are underpaid and under-resourced while the students are forced to wake up at 6am (often not getting enough sleep) to catch the bus, sit in uncomfortable chairs for 8hrs a day with no agency, and then we're surprised that they're not excited by people talking at them all day?

Put another way, let's say you show up to a restaurant that serves shitty food, has a shitty environment, and the server get your order all wrong - you pay for this with your time and money. Do you think it's reasonable for the head chef to complain that customers are ungrateful and should be happy they got food at all? If the restaurant down the street takes the care to get all these things right, are customers entitled for choosing that restaurant every time instead?

Yes, but they're inconvenient as can possibly be. Pharmacies here seem like they have digital prescriptions available the same day, while I almost always have to return another day when dropping off a paper prescription.
As good as the progress is that we make in „these areas“, i can‘t stop to think about that the problem is not, that we do not have enough food on this planet. It‘s just a undesigned designed system with issues in infrastructure and supply chain. But also that is not that it could not be „easily“ done („easy“ in relation to the effort it takes to not change due to different goals). There is just not enough incentive.

I know it will not be the ultimate solution, but everybody who has entertained the thought of eating no or much less meat, now is the time. Especially in Europe and the US. So much food is used to feed food we throw away because we product just too much. Yes, it wouldn‘t magically end up in the right places, but we have to start somewhere.

If just the people on HN would start focusing on this, it could make huge difference…

I can‘t accept that we live in a world where people become millionaires by punching others in the face in front of a camera, meanwhile around 25.000 people starve to death each and every day…

Let‘s do something.
Even if you think it‘s impossible and you have many reasons why it wouldn‘t get solved… let‘s not accept systematic issues as the end.
It should be the beginning. After all, this is HackerNews, right?

Where could we start?
