Your initial statement is still wrong, that you can include a lot of information in a small number of bits. If you have a small number of bits, the overlap will be staggering. Now, that may be ok, but not ok, if you want to present orthogonal concepts (or even quasi-orthogonal).

Also, why do you believe dot product cannot be trusted?

Not OP, but I was diagnosed as an adult. There are brief screening questionaires therapists or general medicine doctors can use as a quick first step. But when I was given one of these tests, I scored a couple points under the threshhold. Later, when a thorough, proper battery of tests was administered by a psychiatrist at a major university medical center, I was found to have significant ADHD impairment. So if you think you may have ADHD, it's worth seeking out a proper evaluation from a psychiatrist. The battery of tests will take multiple hours.

I haven't had a lot of issues getting treatment after my diagnosis, personally. I know some people do have issues, and there are inconveniences like annual drug tests I have to take, but my only regret is not getting diagnosed ten years earlier.

> 75% of the time I forget to take a bag to my car.

I put our reusable ones on the floor in the entrance to the garage and then that reminds me to put them back in the trunk whenever I go to the car for whatever reason. Then I always have them while out.

I've sometimes left them in the car but just excuse myself at the checkout and go fetch them while the groceries are being rung up.

Windows 7 built a design language around it, transparency was never the main attraction.

Which is smart. Contrast is king, especially on consumer hardware where grandma might not see too well in her late age. It wasn't the glass effects of Vista or Yosemite that appealed to people, it was the high-contrast UI elements and skeuomorphic design elements (neither of which are present in liquid glass).

It's a little annoying, but as long as the main domain has a paste that links to the dodgy-looking domain then it's bearable.

Ideally, companies would have a page "all the domains we use" as part of their footer links.

So many companies that should know better are helping to enable phishing by using random domains.

> Clearly computer have introduced a lot more symbols to the keyboard, but for whatever reason, the em-dash wasn't one of them

Forms distinguished by width weren’t added to computer keyboards as separate keys because computer keyboards, like typewriters, solidified when computer displays were monospaced. (And, like other forms like proper opening and closing quotes, limited space on the keyboard was a concern.)

That approach may be a viable heuristic but it will only get you so far. It's like flagging an opinion because it doesn't rhyme with the opinions of others.

That's not what humans do when they are fact finding, though. It's not what a (proper) scientist would do if she/he discovered a great insight or theory and was wondering whether it was true.

The USB-C connectors are mostly for charging, and IME it'll take 4-6 full cycle charges until most are out of vape juice and disposable so they're always accessible. The packaging usually is snap-together with no screws so it's a puzzle.

I'm still surprised to see the fancier LCDs used which range from 2x4cm - slim 1.5x3cm (Digiflower, Raz is super popular.) Most LCD vapes which range from $20-25 are starting to fall by the wayside for $13-15 vapes with simple SMD LED displays with color overlays, (Kadobar, Geek Bar, Cookies, North) easy to make 7-segments for battery/juice status. Some are elaborate with wraparound displays that I've mistaken for flexible OLED and are deceptively cheap.

I'm confident in high volatility forward looking, but not confident democracy is dead (yet). Until elections have been cancelled, we proceed as if they are still on. If action is necessary to restore democracy, that is a possibility to be prepared for.

Edit: With regards to replies, I understand and appreciate the perspective, but the discussion will only lead to the subthread being detached here. It's important, it's valid, but it also is unproductive discussing it here. Discuss it elsewhere with like minded people.

> Uranium is incredibly cheap. Prospecting is not worth it as there are enough reserves to exploit in the foreseeable future.

A huge uranium bubble between 2004 and 2008, which triggered massive investments for prospection... and a ridiculous result (15%). The cause is known: the quest for atomic weapons triggered during the 1950's and 1960's massive prospection, and there is no decisive way to better prospect and few not yet prospected zones.

> Seawater extraction is starting to be competitive with mining

This is periodically announced since the 1970's, and no-one could industrialize. Bottomline: "pumping the seawater to extract this uranium would need more energy than what could be produced with the recuperated uranium" Source: http://large.stanford.edu/courses/2017/ph241/jones-j2/docs/e...

> In addition, we currently throw away >95% of the energy potential of the Uranium > So facto 20 of what we've used so far is just sitting in Castors. And fortunately not in deep geological repositories, out of reach.

It would be sound if a ready-for-deployment model of industrial breeder reactor. There is none.

> And then there's Thorium

Indeed, but not industrial reactor. Next.
Ask HN: What's the most frustrating user interface you use regularly?

I'm a university student working on a user interface design project. We're tasked with identifying and redesigning a problematic UI.

I'm curious about the pain points of a technical audience. What are the most frustrating websites, apps, or software interfaces you encounter in your daily work or life? What specific aspects make them bad? (e.g., poor layout, confusing navigation, lack of accessibility, etc.)

This is a deep misunderstanding, on multiple levels, not the least of which being: Mac App Store submissions, as far as I'm aware and have experienced, go through the same horrible approval process that iOS App Store submissions go through. The reason why no one complains about the Mac App Store process is because the only people who regularly submit apps to it are scammers and low-effort vibe-coders.

The top comment on HN discussions often devolve into various other discussions. Funny that is never 'underhanded' discussion, but outside of the pale when it comes to this topic. You can't have a good faith HN discussion on this topic.

Normally on HN people refute arguments, not resort to just 'bad faith'.

So there's no difference at all between "0", "0.9" and "0.9.3" in cargo.toml (Since semver says only major version numbers are breaking)? As a decently experienced Rust developer, that's deeply surprising to me.

What if devs don't do a good job of versioning and there is a real incompatibility between 0.9.3 and 0.9.4? Surely there's some way to actually require an exact version?

Context: WebPKI revocation is broken. It didn't have to be [0], but it always has been, and likely always will be, now that the industry is moving to short-lived certificates.

Let's Encrypt is now offering a profile for 6-day certificates: https://letsencrypt.org/docs/profiles/#shortlived

With such short-lived certificates, revocation effectively becomes a non-issue.

[0]: OCSP Stapling (esp. with Must-Staple) is actually pretty effective at distributing revocation information in a timely, secure, private manner. There were no real downsides to the spec, which is why Caddy has supported automatic OCSP stapling since, gosh, I think 2016 or so. The problem is that most other web servers didn't -- and still don't -- implement it well [1], making OCSP (without the stapling) a persistent privacy problem. Additionally, many client vendors want to choose what certificates count as "revoked" now, so they use their own CRLs, making OCSP entirely useless, since they only check their own CRLs.

[1]: https://gist.github.com/sleevi/5efe9ef98961ecfb4da8 -- most servers have such a bad implementation of OCSP stapling that it makes sites less reliable, not more.

This is interesting. Thanks for sharing!

As someone who is disillusioned by the state of modern frontend web development, I'm always curious about novel approaches that do things differently.

At first glance, I like that this is buildless and declarative. Supporting Web Components is also a nice touch.

However, I don't like that it abuses HTML attributes for the "directives" feature. I appreciate that these are stackable, and it seems like a concise and flexible way to specify behavior, but at the same time, it's not valid HTML, and the framework shouldn't rely on unspecified behavior of HTML parsers to ignore them. The correct approach would be to use data attributes, which would make the API more verbose, and possibly less flexible, but it ensures future compatibility across browser engines.

I'm also not a fan of attributes having any sort of logic or JavaScript code in them. That is IMO an anti-pattern popularized by JSX and frameworks of the time which we've accepted as standard, for some reason. Separation of concerns is a powerful concept that simplifies development and maintenance. HTML should define the structure and content of the page; JavaScript should define the logic. Whenever you write JS inside HTML, or viceversa, you're breaking this principle. This doesn't mean that JS and HTML can't coexist in a single file―that has been possible since the dawn of the web. But it means that each layer should be concerned about a single aspect of the application. And, yes, I'm aware that Web Components also technically break this, and, no, I don't like it.

Dagger.js takes this to an extreme level and seems to allow JS expressions inside text content, which is surely too inefficient to have any practical value.

FWIW I experimented with own buildless and declarative micro framework a few months ago[1], after a frustrating experience with Vue. I was curious if "primitive" data binding could be used with an intuitive API, while keeping separation of concerns as much as possible, and without abusing HTML. Turns out that it's really not that difficult. It doesn't have any of the advanced features and flexibility of modern frameworks, but that was a deliberate design decision. I don't expect anyone else to use it, but I plan to adopt it in personal projects. So far it has worked well for implementing the options UI of a small browser extension.

Also, for the love of all things holy, please prompt your LLM to tone down the emojis in the docs. It's quite distracting.

I love the Culture novels, and really appreciate the criticism. Thank you. My true love however thought having babies was essential for a good old age. But she was raised in Cambodia. Socialism (that is the welfare state and the promise of being looked after in old age) causes a low birth rate. My "willing suspension of disbelief" includes the idea that "post scarcity" _causes_ good behaviour. Just putting it out there...

That's an interesting way to word "the most efficient way". A solar setup that meets the energy needs of the entire household is going to have to be oversized, which is a waste. Meanwhile, 100% of the output of balcony solar is almost always going to be fully utilized by the household, meaning 100% of your investment goes into lowering your ever-rising electricity bill.

Any time you're exporting to the grid, you're losing out - the rates are never good. Check out the OP's graph. His setup is oversized by about 2x. He's exporting to the grid for most of the day, which is hardly useful, then pulling from the grid after 6pm - the worst of both worlds. Downsizing the solar setup 2x and investing that into batteries would be much better.

> I guess Im more skeptical, especially when this is coming from a single purpose advocacy group

I agree it's unlikely you'll just have solar + batteries used just for LV. However, taking a look at the adoption of storage in California and Texas, I think it's safe to assume an upwards trajectory for solar + batteries [1].

I didn't know much about Nevada's electricity generation, but based on current data [1] there are enough alternative sources to support a sizeable increase in solar generation.

Still, I don't know how much solar will be deployed and I hope nuclear does drop in price in order to speed up the energy transistion. It's exciting to see so many great technological leaps in our lifetimes.

Finally, a shout out to geothermal, which looks very promising. I recommend listening to "Catching up with enhanced geothermal " - https://www.volts.wtf/p/catching-up-with-enhanced-geothermal.

> His point is not that black people are less capable but that DEI policies [cause] looser standards

These ideas are equivalent. The belief that employers are lowering their standards in order to include more black people is based on the idea that any additional black person hired must necessarily be less competent than a hypothetical white person who could have been hired instead of them; that is, white supremacy. In Kirk's words: "You had to go steal a white person's slot to go be taken somewhat seriously."

They don't believe that there are black people who are qualified but weren't hired because of, for example, discrimination, because they don't believe "discrimination" exists per se, they just think of not hiring black people as logical meritocratic decision-making.

> I wonder when in the West we'll start mining rubbish dumps

Never, because we have virtually unlimited space for landfills, and landfill tech has quietly been improving over the last few centuries, to the point that landfills are cheap, non-polluting, and entirely carbon neutral. Countries with less land mass (Europe et al) prefer incineration (mainly to save space, despite it being significantly worse for the environment and much more expensive (although with the newer energy reclamation efforts this is getting better)).

IMO it's not worth worrying about landfills too much. Household waste makes up about 3% of total landfill waste (when you add commercial/industrial/agricultural) in North America. You and your bun wrapper are truly irrelevant in the grand scheme of things.

Revocation has many meanings. No central revocation authority is actually enforced by the BRs, as far as I know. Clients can do whatever they want. The CA can say a cert is revoked but no one has to care. Clients can also say a cert is revoked and then all their client instances start rejecting it. Most clients work this way now, like Safari -- they just distribute their own CRLs.

My dream is to build an open source CubeSat kit (hardware, software, mission control software) with an experience similar to Arduino. Download GUI, load up some examples, and you're directly writing space applications. Ideally should be capable of high end functions like attitude control and propulsion. The problem is that designing and testing such a thing is a rather expensive endeavour. So far I haven't found a way to get funds to dedicate time on this kind of "abstract"/generic project, most funding organizations want a specific mission proposal that ends generating useful data from space.

Yep you do need to be careful with uncaught errors.

When you setup your project you choose the default number of retries and back-off settings. Generally people don't go as high as 50 and setup alerts when runs fail. Then you can use the bulk replaying feature when things do wrong, or if services you rely on have long outages.

I think on balance it is the correct behaviour.

This type of thing would really need to be implemented at the township / local community level at least, similarly to how every house doesn’t have a big electrical substation plugged into the high-voltage power mains with explosive oil-cooled transformers. It’s simply not realistic to think every private dwelling can or should have this kind of capability, to say nothing of the cost. Maybe large communal housing could. Ultimately it’s a sort of social optimization problem and I don’t think giant individual capacity solves it efficiently.

One thing that could possibly work better IMO is something like a small local renewable fuel economy where excess power is used to produce hydrocarbon fuel by catalysis of electrolyzed hydrogen with carbon sources, and individuals can purchase this fuel to recover the energy, or possibly the power plant could use it during solar lows.

The advantage of this type of system is that it’s not really capacity limited, as long as you have enough fuel storage, which is simple to build more of.

of course, you could just use alcohols distilled from fermented plants instead, but that’s not as sexy.

Rooftop solar doesn't require additional land to be purchased, reduces the need for more transmission lines, and reduces transmission losses. I don't know how big these all are but it seems plausible they make it a better deal than industrial solar.

Batteries on the other hand feel like they take less space and thus could be colocated near consumption without having to be on consumer property. Warehouse size within the city. Transmission costs would be minimal.

>Meta also secretly linked user data with other information to track users’ activity on other websites without their permission — despite Apple in 2021 introducing measures explicitly requiring consent, according to Purkayastha’s filings.

That's frustratingly vague, not to mention it hinges on the complaint of a disgruntled employee. Facebook finding some way to bypass cross app tracking restrictions would be much more controversial than if they bought purchasing data (grouped by email) from data brokers, and then joined that with their own datasets, for instance.

My biggest Problem with these devices is

a.) the world of electronics is moving too fast

b.) My lack of skills and time to build something really cool with something like this

A while ago i bought a licheerv nano (similar to luckfox pico or Milk-v duo) to build an open source iPod nano via usb-c audio Jack and the open source buildroot for the licheerv nano.

I did not find a suitable 2.4 inch or at least < 3"touch display that worked with the integrated MPI port.

With LVGL it should be doable to build a small portable audioplayer with acceptable features... But not for me :-)

Diesel lasts longer, but you should also be polishing the diesel fuel to keep it in good condition, which is another point of failure. When fossil gas is available, it is usually elected as the fuel of choice because this is unnecessary (as the generator is hooked up to gas pipelines, and no storage consideration is required). Propane will last forever in a proper container, but poses more storage risk than diesel.

TLDR Diesel generators where you might be without mains for a while and intend to replenish the fuel with deliveries during the outage, fossil gas for use cases where gas delivery pipelines are available (urban, suburban), propane for offgrid use cases (rural, cell towers, etc) where fuel longevity is a concern.

Absolutely!

And even this is a challenge!

We just weren’t built for doing more than one thing at a time out of the gate, and context switching is our achilles heal. (Not to say there aren’t extraordinary examples to the contrary, its just not the default and requires a lot of practice. I’m thinking specifically about musicians but most people aren’t ready for the kind of commitment necessary to reinforce the neural pathways required to develop the skill)

You hit on something really deep about variety. A conversation near and dear to my heart, sadly this forum is not really conducive to the kind of long form dialog the topic is deserving of.
