I agree guidance is needed. However it is much easier to guide someone if they have other basic skills. If you don't know basic logic you will do exactly the maintenance activity I teach you without noticing that some other part is broke. If you can't read you can push buttons in the right order but if you make a mistake you won't be able to understand the error message.

Once you have basics which don't need digital stuff I can teach you more quickly, but it will be specialized to areas I know deep : I hope it is useful for you. Don't ask me to teach you medicine, I know my first aid but that is just enough to get someone to a doctor who takes over doing things I don't know how to do or teach.

I picked doctor above because I can guarantee that any target group of humans will find it useful to have a few people to spealize in it. Computers are great, but it isn't necessary to have as a specialist in every village.

As I've discovered in the past few weeks of archiving a soon-to-be offline service: archiving is tricky and often requires tampering with traffic.

The IA uses a MITM proxy [0] to produce WARC files from intercepted traffic. Another software suite for producing high-fidelity archives injects JS [1] into pages served by its MITM proxy.

Yup, and if they reduce power consumption (and heat generation) per core, they can cram more in the same device without having to upgrade the cooling or power supply, and they'll have to throttle less if temperature limits are reached. It's always worthwhile to get more performance-per-watt.
He completely rewrote CryptoCat in 2016 and that still wasn't good, the security page was at https://web.archive.org/web/20160407125207/https://crypto.ca... and there were still pretty bad issues, notably the file sharing disclosing the exact size of the file shared, despite him stating "Cryptocat makes the following assumptions: Untrusted network: We assume that an attacker controls the network and so can intercept, tamper with and inject network messages.".

Probably even better. Water has a nice heat capacity (I think about 10x as much as copper), but maybe that isn't that important for such a solution as long as the heat gets used. Even if we would just get 10% of the invested energy back, it would be a huge boon already.
What a beauty!

"The Thing" was designed by Soviet Russian inventor Léon Theremin, best-known for his invention of the theremin.
The way I solved this was by buying cheap weather stations from AliExpress. Many of them come with multiple temperature/humidity sensors powered by batteries - for as low as 70$ for a station with 4 sensors. Those sensors transmit on 433 MH or 838MHz radio which has excellent range (20m+ through walls) and long (months+) battery life.

On RPi side I only had to get an RTL-SDR receiver and run https://github.com/merbanan/rtl_433 on the RPi itself to decode the data.

It was significantly cheaper than going with BLE or WiFi sensors.

> In general, don’t whiteboard sketches have a hand-drawn feel?

Whiteboard sketches on a physical whiteboard do, but in general, computer “whiteboard” sketches are a mixed bag that IMO land more often on the side of straight lines and perfect circles, especially if you look around at which computer whiteboard products are commercially successful.

> Seems like the trick would be a tool to give diagramming tools a hand-draw whiteboard sketch feel, or take hand-drawn whiteboard sketches and give them a diagramming feel.

Here’s one example of the former:
https://matplotlib.org/xkcd/examples/showcase/xkcd.html

The latter, converting sketches to diagrams, would be neat and is an interesting & difficult problem.

The thing that neither of these use-cases really cover is the need for a fast iteration / ideation tool in the exact same role as a physical whiteboard. Once you’re concerned about the presentation & look, the majority of time is spent working on the layout and the presentation because it takes longer to make it pretty than to just work out or communicate an idea without regard to beauty. Very small changes to where something goes or what it looks like can lead to a large and time-consuming ‘refactor’ of a diagram.
Thanks, but probably not.
> What about someone who notices that they are getting older and are starting to develop aches and pains and decides to start buying health insurance that they had avoided when they were younger because they seemed to have been made out of rubber back then?

That's exactly the reason the ACA made health insurance mandatory, to avoid that scenario which would require insurance companies to make the policies more expensive in order to compensate for the higher average age and worsening average health of the insured pool, which further incentivizes the avoidance, and so on, until we're right back in the same situation with a high-risk pool and unaffordable premiums.

Incidentally, that doesn't mean that avoiding health insurance if you are young and healthy with no dependents is actually a good idea at the outset, since many common health conditions like injuries from car accidents don't particularly discriminate by age.
I think I would take books and copyright over a free internet, and a lot of other people would too.

>Enforcing copyright in the 21st century requires sacrificing computing freedom as we know it today. Computers would only execute approved "lawful" software.

>Subversive programs which do things like play movies without consulting the rights holders first would be banned. That would surely mean the end of playful hacking and the free and open source software community.

How does the second part follow the first? 100% freedom in all forms is not a pre-requisite for opensource software. There are plenty of things you can't and shouldn't be able to do. I think this is a false dichotomy.

Heavily inspired by vi text editor. WYSIWYG but sans the mouse. Some of the things you can do with it:

* create an element before/after/begin/end/around other elements
* easily toggle classes/attributes/styles
* move/clone/edit many elements at different places at the same time (just like Sublime's multi-cursor simultaneous editor)
* quick undo/redo
* CSS framework support (quickly imports externally hosted CSS files such as Bootstrap, Tailwind, UIkit, Material, etc)

To start creating a Bootstrap page, when you go to https://vivpage.com/pages/new, just press colon key to get into command mode, then type lf bootstrap and hit enter. You're ready to create html elements! Here's an easy one for a hero section:

$div -c container
$div -c jumbotron
$h1 -c display-4 "Hello World!"
>p -c lead "We change the world one Bootstrap class at a time!"

> Are you suggesting that if you sat a child down in front of a computer and walked away, they wouldn't eventually know how to do most things?

Yes, that is exactly what I am saying. And yes, I have the opportunity to watch children and their interactions with technology. And also, the random clicking without fear gets them to locked tablet/computer with things turned off, random files deleted and them being scared cause nothing works suddenly.

Also, I remember VCR and no, the kid was rarely the only one knowing how to set the clock or almost never the one who set the clock first when device came new. Typically someone else set the clock when device was new.

When you put the kid in room with crayons, overwhelming majority wont learn to do art in any reasonable level. If you put them into room with wood and knife, overwhelming majority wont discover woodworking techniques.
Ideally, the document format should specify which parts are in what language. Both MS Word and HTML can do that.
Good question! In a case like that you'll have to be a little more aggressive about copying libraries from the build container.

How to quickly plan and estimate an MVP
I do worry; some years ago they added some features to MacOS that made it look like they were headed towards a touch screen interface, convergence with their mobile products - Launchpad, mainly, which I hate and never use and I don't think there are many people that do. I mean yeah, using Finder to list applications beyond what's in the bar is crude at best, but it works fine for me. I don't use Launchpad and have the application bar hidden most of the time; spotlight works for me for 99% of my use cases.

But that's just one piece of anecdata. I prefer my MacOS to remain roughly how it is now.
I suppose it depends on how quickly they go from "Apple says this legacy" to actual legacy tech.
> The power plant is run precisely when you don't have excess power to store. Conversely, you don't have concentrated CO2 when the power is available.

Unless you have some way of buffering the CO2. Biologically, this is what CAM photosynthesis does [1], and i have a vague memory of there being an industrial equivalent. Something like dissolving the CO2 in calcium hydroxide, to make calcium carbonate, then later on sparging it with hydrogen to recover the carbon?

I'm sure that plenty do. I somehow discovered Emacs in the Terminal on the family Mac when I was much younger and I consider that the start of my interest in how computers work under the hood (aside: thanks to the GNU Emacs developers for making the manual so accessible immediately after typing `emacs` into a shell).

The biggest positive influence from my parents and other adults in my life was regulating my video game time but not my "playing with the computer" time. I was pushed towards reading and learning about computer stuff instead of playing games and watching videos.

I'm sure that some kids need more guidance, but in the age of the Internet, the subtle push away from entertainment activities might be enough for many.
It may be necessary for the micro to run slower in order to be stable, but to my knowledge no system for making that adjustment automatically exists in the vast majority of systems. The main problem being it's hard to detect. How do you tell if the CPU is on the margin of failing without a huge amount of extra circuitry? It can be hard enough to detect that it has had a fault. It's not due to lack of interest: such sensing approaches have been patented before, but don't seem to have made it out of the R&D lab.
It still feels like you dove into the deep-end of the data collection conspiracy pool before considering other more-likely explanations, like "They have the information now to know that, in general, using color to make the rest of the bar less prominent wasn't sufficient to minimize users feeding data to malicious sites."

Absolutely. That's part of why I'm delaying. A professor at the University of Michigan is working on a similar project and I want to catch up with her.

Health and fitness research is amazingly vague and.. well shit. Or no wait, the term in underfunded. We should be sinking hundreds of billions into figuring out these things.

The stuff here talks about the amount of physical exercise to stay healthy! In what other field would such things be acceptable? You just cant say "Stay healthy", there is no such thing. (at least not today)

I want to see the entire chart derived from huge data sets but I believe the really interesting data to live around minimal activity. There is probably a sweet spot around 20-100 steps where fewer really starts killing you really fast. Then we can get to addressing the issue and possibly improve average/collective health dramatically.

I wouldn't mind showing up for bench marking 1 time per year. If the report puts me in a group slowly killing themselves I would be interested in solutions. It might sound absurd but I already pay 25 euro for some smokes. They say it is for my health but Nicotine addicts don't need to smoke.
> What I think is most plausible is one large manufacturer will consolidate designs and rent the equipment to do the harvesting

No way. Everybody wants the machines at the same time. You're going to incur the capital cost of buying/manufacturing the machines, the cost to store and maintain them for 50 weeks out of the year, and then rent them out at a profit for 2 weeks? No, the farmers will just keep hiring human labor.

If you can solve this problem, you can sell a lot of machines for a lot of money for a short few years. After that, they'll be a commodity and be dominated by all the other capital-intensive manufacturers that can run a factory better than you can.
My guess is that it is some larger corporate client with a middleware app they pinned the cert into. An app they built on Heroku hurriedly because it was fast and cheap to get started and they didn’t expect to need to scale. Then as can happen it became important and they scaled anyway. They probably lost the talent that built it so they don’t even remember how it works.

All of this is assumption based on how they seem to buy enough compute at Heroku to have sway over rolling back this change of cert provider.
This is perhaps a rather pedantic point, but do you really mean government _provided_ healthcare, or simply government _funded_ healthcare?

Very few countries have the former (the UK famously does), and many societies would be considered civil have the latter.
It's not in the WebRTC API. You can change the volume on the audio tags you create, or you can pipe the audio media stream into a WebAudio graph and modify it there.

I've built a number of WebRTC apps over the years. Recently, I built just such a thing as you described and open sourced it: https://www.calla.chat. I opted to build it on top of Jitsi Meet this time. It's actually advantageous that it's not through the WebRTC API because Jitsi doesn't give access to the raw WebRTC commands. But hijacking the audio elements it creates is completely doable.
While I am excited at the possibility of ditching Gmail, one of the main things I am most excited about is that DHH has been hinting at a lot of new tech to come out of this including what he mentioned as the simplicity of Rails for the front end world.

The methane comes mostly from burping. [1]

I objected to how the article draws misleading comparisons amd I gave two examples - how the scale of emissions is distorted, and how offering up milk substitutes as an alternative ignores how most dairy is actually used. I think that's enough to convey my point without a line-by-line breakdown of the entire article.

I do like that they pointed out that consolidation has driven up demand, and at the cost of rural businesses and communities. But it's overshadowed by the rest of the article. For example, the grain alternative would just make consolidation worse.

This isn't about me wanting to drink milk, eat meat, and ignore climate change. It's about how we're replacing our traditional distributed and varied food supply with corporate monoculture.

The article is written with such a heavy bias (intentional or not) that it seems more like an opinion piece. I'm not angry. I'm just disappointed in the journalism.

Ask HN: Software for online group meetings or discussions?
I'm looking to host online science discussions primarily between a small group of people but with the potential for others to join to listen/comment/contribute. Right now the plan is to use Zoom with someone taking notes but I was curious if there were other alternatives (besides WebEx, Google Meet, etc.)

I thought I had read somewhere on HN about an alternative to podcasting where a group of people had a discussion then they could bring in guests to join the conversation.

Alternatively, if someone has a combo software alternative that would be interesting as well (Slack + Facetime + ...)

> But vice versa, using the process and knowledge we gain from 5 nm chips might improve the lifetime of 7 nm chips by orders of magnitude

Probably not. The problems at each scale are very different and tend not to have much overlap. Process limitations also exist regardless- say you figure out that patterning transistors at 3 nm increases lifetime in a way that is applicable to 7 nm. 7 nm still can't take advantage of it as long as it requires 3 nm scale patterning, if there is even overlapping technology. Even if it requires adding a new step, say a wafer treatment that is necessary at 3 nm but optional at 7 nm, the economic benefit from increased lifespan is probably not worth retooling the old equipment.
