It's pretty easy in California to go to Community College while in High School, I took second year algebra in my high school, and on the recommendation of my high school teacher took Trig at the local community college (next door to the high school luckily) at the same time. There just wasn't any open spots at the High School. This was 1980 or so. My son took calculus really early maybe 10th grade. So he took multivariable calculus and differential equations at a local community college. I think a friend one grade above him also did the same. So I think it's possible for people to find solutions if teachers work in good faith. I think the real problem is just that I don't think the program will have the intended effect. There is no substitute for having a strong foundation, and pretty much if you get a C or worse in one class, you will have a much harder time going foward, but there really doesn't seem to be any systematic way to help those kids. Fortunately things like Khan Academy do exist, and for those kids who are motivated there are lots of doors open, way more than when I learned this stuff as a kid. The real issue is motiviation to learn math, most kids are not.
Do you know whether the GCC Ada, Fortran, Go, D and Java frontends also assign full copyright to the FSF? Are the copyright of all dependencies likewise assigned to them?
It is a real achievement in plasma fluid dynamics engineering to have got a stable plasma so hot for so long.

However, it does not mean there will ever be practical, commercially competitive power produced using this method or anything much like it. The total mass of material fusing in a reasonable volume is so small that, despite the large amount of energy per nucleus fused, the power produced is nowhere near what would be needed to pay for plant construction, never mind operation and maintenance--not to speak of having to replace all the most expensive parts after minimal use, as they are destroyed by neutron irradiation.

Thus, every cent spent on this project actually takes us farther away from a renewable-energy future, vs. that same money put into building out wind and solar capacity and storage.

This is a fundamental problem in any hot-neutron fusion system. The real reason governments pour so much money into Tokamak fusion projects is as jobs programs for hot-neutron physicists, and subsidy for contractors, to keep them all ready for when they will be tapped for weapons work.

This is similar to the way NASA is still funding SLS: nobody expects it ever to be useful for anything, but the contractors involved need to be kept busy and employing staff for when a new missile system is needed.

There are lots of probably-practical ideas for aneutronic fusion that don't get peanuts because they fail to provide a conduit for funding to thd right places. E.g. D-H3 fusion in FRC may well be practical for spacecraft propulsion, but development is on a shoestring budget, hoping to test something in maybe 2035.
The part where he is wrong is the premisses that every new computer must more or less gives up all the software of the previous one in order to reach a new trajectory.
This used to be more or less true with early 80's computers, such as Apple II or C64, but that's exactly what changed with the PC. 32-bit arrived, and kept compatibility with 16-bit alive. Windows arrived, but (initially) kept compatibility with DOS. etc. Fast forward today, and the Mac M1 arrives, and can still count of Rosetta to continue running x64 applications.

This is a key change, and a necessary one, as rewriting everything for a new system is just a killing blow.

Unfortunately for him, this mistaken analysis is exactly what lead Jobs to the NeXt, a new computer re-invented from scratch, dropping everything that existed prior to rebuild it. This costed too much time and energy, and the NeXt was late, expensive, incomplete, a commercial failure. Jobs was lucky to be bought by Apple before going under.

And arguably, that's a lesson he learned well. Immediately after, while taking command of Apple, he states basically the opposite : re-use everything that can be re-used, especially open source. Only redevelop what you think you can do better.
A Brief History of the Amphicar – President Lyndon Johnson’s Favorite Car (2020)
I used to blog. Many (9) years ago. I took a break (https://objology.blogspot.com/2012/05/stepping-out-of-balloo...). 9 years of polyglot-ism later, I've toyed with returning to some sort of small b blogging, just for the therapeutic nature of writing about what I learn and do.

But I'm honestly at a loss where to do it. I don't really want to do the hosted-for-monetization thing again (Medium, BlogSpot, etc). I've looked at GitHub Pages/Jekyll, all the cool kids seem to be doing that? It seemed kind of complicated and end-runny. And it wasn't clear how much control I'd have over my future that way?

What do other small b bloggers do now days to control their own destiny and keep things simple?
> You can only search a log for the time that you were logged in and saving it.

That ignores the possibility of the data being synced between local system and the server. Slack is already in the cloud, so cloud options are on the table. And so is syncing data.

> suggesting search would be better locally is plain silly. Search is obviously better done at the server.

The reverse is obvious to me. Slack search, like all web SaaS search tools, is really bad. I could do better with grep - and it would work faster, and I could actually trust that it searches through all the messages, instead of giving me some eventually-consistent view into results of a query that is only tangentially related to what I requested. And they wouldn't be able to tell me which properties I can or can not search by.

And I'm not talking theory - in the past, I did some spelunking in many years' worth of IRC logs in a folder on my drive, and the experience was much better than searching for anything in Slack.
Intel CEO says semiconductor shortage could last year
I use Wikidata data (in a non-academic capacity) shrug

It's not that easy to work with, but there aren't any good alternatives in my case. Freebase died. DBpedia doesn't compare. Domain-specific databases don't have the data I'm looking for (or it's woefully incomplete and/or hard to link to external entities) because it straddles multiple domains, not to mention they're usually not free. I for one am very thankful for Wikidata existing and seeing good activity.
Those social media contents you've listed there is nothing anybody wants to keep. Let's be real here. This is throwaway information. While outside of the edgy cool startup bubble the rest of the professional information is still being saved somewhere. Sometimes even saved AND printed. No matter if it was on Slack, Teams or wherever.

> His generals really screwed up the Eastern theatre in the late 1940s. Hitler knew they needed to secure the oil in the Caucasus but the generals were myopically focused on an Eastern advance and on securing useless symbolic military wins that contributed nothing towards the oil effort.

Correct me if I’m wrong but the attack on Stalingrad was a diversion for a symbolic victory ordered by Hitler. And when German forces were getting beat he ordered them to fight to the last man, and the general in charge was a rule follower and did not disobey orders.

In other words, I think you’re blaming the wrong person here. Germany’s generals were on the way to the Caucasus to do exactly what was needed (from Germany’s perspective) but Hitler stopped them because he was going crazy and wasn’t a good military commander.
90s volvos were absolute tanks . My friend had one and it got rear ended while parked and both the car that rear ended it and the car in front of the Volvo got totaled. The Volvo was pretty much fine and just needed a new bumper (which was easily done as the bumpers were distinct from the body work).
>Sounds good. Where is such program? This is surely not a very novel idea, but where is it?

Every office in the nineties. Windows 95 + Office on the desktop and a Windows NT Server sharing the files. I'm not saying we should try and wind the clock back but it was a solved problem.

I feel much the same as you, smoking to me was always an easily excusable pretext to be alone or speak to complete strangers as required.

I also felt it helped to bridge the strata in the workplace, as a junior I'd often end up sharing a cigarette with an exec or manager of some kind and hear about goings on in a different part of the company or from a higher level which would help to piece together the puzzle of how the business was being run.

It's been many years since I've smoked habitually, a few months since doing so socially, I don't feel the urge, but I do miss the idle moments it allowed for.

There really is nothing quite like it. The closest thing I've found is tending to weeds in my back garden.
Perhaps it has to do with the type of fiction and maybe a little bit with school? When I was done with high school one of the things I celebrated was that I would never (have to) read a fiction book ever again. Literature class turned me so off from reading that I was fairly convinced about this.

A couple of years later I stumbled across Light Novels, which led to Web Novels, and eventually more fiction of other types. Nowadays I sometimes wish that I would read less. Sometimes my binge reading can get out of hand.

Perhaps there are others that have been turned off from reading? Perhaps they simply haven't come across the type of fiction that would grip them? Fiction is about entertainment after all. Books will offer you the widest variety of stories. More so than any other entertainment medium. There should be something for most people.
Ask HN: How hard was it to get your product out there?
For all you out there who've launched a bootstrapped startup in the past five years and growing, how hard was it to acquire customers during the early days?

I have spent a good amount of time working on product development and think my product is ready but the road ahead seems really daunting. It just seems so hard to get the word out these days if you're not some influencer with a decent amount of following.

I'm trying to find out because I'm about to launch a SaaS and am going with the pre-launch lifetime deal for early adopters approach (https://plantoost.com/pro/lifetime) and I'm looking for ideas on how to get the word out.

If you used to be in a similar situation, what has worked best for your startup initially and were there any tweaks you had to make along the way? What have you discovered to have worked to acquire customers? Was it cold email marketing, social media outreach, content marketing, forum posts, affiliate marketing? Everyone out there seems to want to sell me a package.

A couple years ago I posted a 'Who's Mentoring' post [1] on the same day that the monthly 'Who's Hiring' post went up. Doing a search, [2] I can see that others have posted in the same vein over the years. It'd be great if the HN community could facilitate mentoring for targeted needs.

Over the years, I've talked with various folks from HN, and even launched partnerships with a couple startups that I met through HN. It's a great community, and I'd be happy to give back however I can.

> Sure, most clients let you automatically save logs, but they were just text files you opened in any text editor. They weren't in a special IRC format, and you didn't open them with your IRC client.

Yes, that's exactly the point. You owned this data, you could do whatever you wanted with it, and it was stored in a format that was both trivial and most fitting for the data stored.

> Hell, you couldn't open them with your IRC client.

I'm pretty sure you could in some clients, and some definitely pulled stored logs to backfill the chat after restart. Though I haven't done that myself (instead I relied on a bouncer to supply the backlog on connection).

> There's no reason you can't just ctrl-C a bunch of stuff out of a Slack chat and ctrl-V it into your text editor. Only difference between that and IRC logging is that you have to do it manually.

That's a world of a difference. In Slack, it's painful to do, and if you haven't done it when you first saw a message, it's going to be even more painful to do after the fact.

Right, I love WebDAV too, it’s a really underrated protocol.

But tbh, it’s underrated because of the crappy Windows implementation causing explorer to hang as soon as a fly causes interference.

It’s sad because WebDAV could have been (with some added ergonomics) the missing link between the filesystem-desktop metaphor and the cloud apps.

Exactly! Stacked logic is the key to the fabled smart matter. Heat dissipation is going to be an issue, although I think IBM had some ideas on microfluidics. Also, there's been a ton of work on dilution fridges for quantum chips, and some startups are doing cryo logic, these two could complement
That's a reasonable take when the comparison is between a landmine and a present-day autonomous drone, but the latter technology is in its infancy. A large part of the fear involves the future. As scary as inadvertently stepping on a landmine is, it's a whole different level of terror than running for your life from some relentless Terminator-style robot.
I recall years ago IBM had an experimental solution to that that involved liquid in between the layers to transport the heat (vague memory, I think they used an analogy to blood).

applied mathematics earlier on, especially with the use of computers, sounds fantastic to me.

of course everyone is going to argue about equity or lowering standards or whatever... but personally i think bringing more applied math to k-12 will be a boon, especially in the age of computers.

maybe by demonstrating how fun it can be to use the tools, more kids will be willing to suffer through the abject monotonity of rote memorization for doing hand calculations.
With an H-19! I'm jealous... (I gotta get my two H-11A boxes running with the pair of 8" floppies. Another 'rainy day' project!). In the day, I built 3 H-19s to save a few bucks, and that was a LOT of work. Another one which was even more a pain to assemble was the kit form of the ADM-3A. Still, for the time, it was a lot of terminal for the $$.
I don't watch a video. I did look at what is in your profile, though. It is the kinds of thing I might use NNTP instead (although having a web interface can also be helpful for the users who prefer that). (Actually, I have a NNTP server myself, and have partial work of a optional web interface too, for the users who prefer that; it displays a link to the NNTP if the scripts is not enabled so it can work even on Lynx (which supports NNTP) or just in case the user prefer to use the NNTP.) I do like that you have accesskey attributes; many web pages don't use it. I did see the git repository about it too, and I had read the documents there too.

(If you have a computer with internet, and if it will serve a plain ASCII text connection even not needing HTML or Telnet commands, nor VT-100 or anything like that, nor non-ASCII characters, then it can work if you have internet, if you have a computer with a keyboard (using a telnet client, or just nc, or whatever); that is the minimal possibility. So, it is another possibility maybe; of course is not only possibility.)

Fore, it was _how_ I was smoking more than anything.

It was in large part a social factor. Most of my first line leaders smoked in the Army. Most of my co-workers smoked getting out.

I had tried a few times without ever getting "hooked," until one random day it was about to rain. I was inhaling deeply (desert rain has a great smell), and took my deepest drag yet.

I finally realized I had been smoking in my "mouth" it, so to speak. From there the head-clearing buzz was present, and it truly felt amazing.

Then it started to go away. Take another drag, and never quite reach that again.

Years pass and you start to wonder why you still do this stupid, nasty habit. At this point, you're already addicted and like the beautiful light switch analogy another user gave, it is a conscious effort to always quit, not to pick it up again.

I somehow only picked up smoking a year after separating, not trying to insinuate a 1:1 relationship there. Now drinking... ;)

Heathkit was my intro to electronics in the 1960s and early 70s. My father gave me a Heathkit electronics lab that consisted of a board with a bunch of components, spring connectors, various lengths of pre-stripped and tinned wires, and a project book full of fascinating experiments that I did over and over. He also built our family color television and stereo receiver from Heathkit projects. I remember watching him work on them in his shop after dinner, soldering components into place for hours. Both of those units lasted a good long time, too.
I quit smoking with Carr too, some half dozen times. It would last for a few months, then I would start again after a few beers. The latest trick, good for two years now, is using nicotine-free rolling herbs (edit: things they give as filler to roll your joints, a mix of things like papaya leaves, tea, etc)
I do not see why not, people were thinking like that 20 years ago, it isn't like your 3D engine will have to implement all techniques from the last 50-60 years (no need for wolf3d raycasting, for example and a lot of the shading and lighting code will become simplified once everything is capable of raytracing). Also AFAIK UE5 contains something like 5 render paths for different rendering approaches for all the different hardware and game types they need to cater to, but a specialized engine wont need to be that generic.
Feature-wise, there's no fundamental difference. All of it boils down to a matter of taste.

But in terms of support, I must say Nix is currently ahead of Guix. It has a large quantity of packages that surpasses any other distros[1], (almost) all of which goes through review. It also has support for non-Linux platforms, namely macOS and BSDs. The community is large and active, and there are various avenues which you can reach out for help.

So if you're interested in either but don't know which to choose, I'd recommend Nix. If you're feeling adventurous and also like Scheme, Guix would be the way to go.

> but for most users, they shouldn't care where it is saved, ala dropbox. They just want to access their files.

Yes, but it does matter where it's saved, because the location and method confers ownership of the data. "Possession is nine-tenths of the law" is the rule of modern Internet. It shouldn't matter whether my photos live on my drive or in a third party's cloud, but it does - because in the cloud setting, the company dictates what I can and cannot do with my data, can pull shenanigans like applying strong lossy compression to uploaded photos, and they will eventually take my access away - either I cross the ever-expanding terms of service somehow, or they'll just go out of business.

In my experience of both managing my own data and helping non-tech people, filesystem vs. cloud data durability is really a wash. People seem just as likely to lose their local data due to drive failure or accidental deletion, as they are to lose access to the cloud storage (or have the company disappear from under them).
If governments truly gave a shit about their people and medical resources that's exactly what they should do.

There was a study that claimed to prove that antioxidants can prevent the stress that causes sleep deprivation to be fatal, and that this fundamentally originates in the digestive system across quite different species.

They didn't extend lifespan compared to baseline, but they restored baseline lifespan to sleep deprived subjects by feeding them various substances.

They tried a bunch of antioxidants, the most readily available one was melatonin, I think, but it's not clear to me what it all means.

If mice and fruit flies can live without sleep, would it work for humans? Do antioxidants help humans with sleep disorders?

All I know is that over the counter melatonin does not seem to work any miracles for me. I have no idea if it would make me capable of staying awake 24/7 if forced.

Lifespan is a separate issue, but you could look at eliminating sleep, if possible, as living 1/3 (or more) longer.

The author of this article doesn't have a problem that "rethinking the computer desktop as a concept" will help with - they have an organisational/concentration problem. With 75 tabs or 88 preview images the user can't possibly see the wood for the trees - or the problem he's working on from other clutter.

I have 20 or so projects on the go but have 6 or so apps and rarely more than 4 or 5 browser tabs open for longer than a few minutes.
