It's a chart of a discussion on Twitter. I simply use two fingers on my trackpad and scroll back and forth, up and down, and explore the chart as it stands. If you can suggest an easier way to render it then I'd love to hear it.
Not a problem ... I'm involved with outreach, enrichment, and enhancement, so creating a DiGraph or concepts, although impossible, would be an excellent goal. I know groups that are making progress towards it for the UK school curriculum, but it's hard, and I'm not entirely sure that what they're doing will turn out to be useful in the way(s) I'd hope.
What caught my attention about your site is that I know from experience how hard it is to create a fork of gwern.net: https://www.shawwn.com/swarm I noticed lots of little details in yours, like the fact that the anonymous feedback form is different, and that you exported your logo with potrace. (Killer logo by the way!) All of that took a lot of thought and effort, and it was a delightful surprise to see that someone else did it independently. It'd be neat to compare notes with you!
Thanks a lot for the thoughtful content, and the tree of concepts. I don't have nearly as much training in math, so it was quite helpful. :)
it would be! meanwhile, here's a bare sketch of the prerequisites needed to understand the theorem statement (the proof needs some more):
1. elementary algebra (functions, graphs, etc)
2.1. single variable calculus (limits, derivatives, integrals, series)
2.2. elementary number theory (modular arithmetic, euler's and fermat's theorem, etc)
3. abstract algebra (groups, rings, fields, and homomorphisms between them), abstract alg. also clarifies a bunch of elementary number theory.
4. the very basics of algebraic number theory (ideal class group, discriminant of number fields)
it may seem like a lot (especially to a school child who just learned arithmetic!) and in some sense it certainly is, but many of these concepts reinforce and build upon each other, so when you've understood them, it doesn't seem like much at all.
Ug the acer ferrari, it was accidentally like a real ferrari:
Acer was probably the worst manufacturer at that time and needed to put a desktop CPU in. They didn't put any hardware/firmware throttle in so they would overheat and trigger the CPU thermal limit if you could not install an OS fast enough.
When our procurement office let us choose them as one of the few options, I assumed it meant someone in procurement was having a midlife crisis.
Why not just put stickers on a run-of-the-mill look laptop to personalize it? Having some different colors within the same model might be a slight improvement in cheerful looking meetings, but procurement generally can't be bothered with extra constraints like making sure the right computer goes to the right person.
This seems like an install/setup guide for an alternate package manager that installs an almost normal webserver?
I don't really get what yunohost is supposed to be providing AFA simplifying the experience, given it is apparently not it's own bootable image of a distribution.
I think most existing distributions have a webserver that comes up and serves a directory in /var and they don't serve any PHP. Unless you know php or want to do click and pray with wordpress, I would consider no PHP/etc and no enabled modules the right config to start a home blog.
As such, I think this is really too advanced for the stated audience and more of a description of a possible later option.
I think the little Arm boards are good enough now for surfing, etc.. But for a desktop with lots of RAM and cores an AMD Ryzen would be good.
The only use I really have for a lot of cores is compiling the software I am using on the machine, which seems like circular reasoning for consumption, particularly since browsers and such things with long compile times are things I least want to contribute to.
I find this article a bit disappointing compare to earlier ones from the same blog.
To summarize my dislike, I find the premise that:
1. Trying to get free as in beer CPanel style service while using Tor for your own privacy and wanting family to accept unsigned certificates as a sign of trust in you. The innapropriate trust is in a hosting company with an unclear business model which can include relying on grey areas to sell MITM access to a 3rd party for injection of spyware downloads.
I find this markedly worse than the pre-existing standard:
2. Forcing friends and family to accept your preferred large provider for file sharing or photos that is probably giving you several gb for free and has some reputation to maintain for their freemium upsell.
I would have preferred:
3. Using classic shell access ~/public_html from some small UNIX community or other non commercial site.
4. Using more unusual setups to introduce friends and family to p2p networks, filesystems and similar.
"Stockdale had no reason to think that the day’s mission was to be anything unique.
The flight in September 1965 was part of his third combat tour of North Vietnam, serving as Wing Commander of the aircraft carrier Oriskany. Despite his misgivings about the purpose of him being in Vietnam, he was a competent and skilled career fighter pilot. Nothing suggested he shouldn’t expect to make it back home that day - let alone that decade.
But sometimes life deals you a lousy hand, and it dealt Stockdale quite an unhappy one.
While trying to aid trapped American soldiers on the ground, he was suddenly falling out of the sky and hurtling towards a small Vietnamese village. His plane was on fire, the control system shot out by North Vietnamese who had used the grounded soldiers as bait, and he didn’t have much choice beyond punching out of the plane."
Good stuff, I also find Arch Linux's documentation fun and absorbing (and quite often a sufficient overview when looking into configuration) even though I've never really used Arch.
One thing I find interesting is older/slower recycled hardware and configuring/compiling everything yourself hit the same kind of yankee conservativism for me, but don't work so well together unless you go to pretty extreme minimalism, such as never using the large evergreen browsers (which can take a week to build on older hardware) or fancy compilers.
In the distant past, I used gentoo and treated a constant build cycle as its own sort of meditation. More recently, I moved to nixos and accepting it's defaults builds (and therefore cached builds) as a sort of bug oriented version of Occam's razor. The least changed system is the least likely to exhibit an unreported problem.. But it is hard to resist the pull of testing builds which brings in the draw of the best tools which is sadly still the newest instead of quality tools that last in a more traditional trade.
I generally like the technology and cs-related submissions, as well as the occasional mathematical or philosophical article. Not sure that I'm keen on the "fighting" articles that I'm seeing on the list. Those don't really match what I thought this site was for.
On the netbook theme, it was originally Microsoft that used licensing to limit the amount of RAM they could ship with (1gb?) and support(2gb). This made it impractical to sell anything in the low end on screen size, etc, but above their limit on RAM. It was already impractical to sell anything but windows unless you sold no Windows or AMD if you sold any Intel.. So Microsoft/Intel licensing and illegal behaviors kept a gap in every vendors product line between terrible and medium range for as long as they could.
I think in the next phase, the factor was Intel, older Celerons support more RAM, but Intel realized cpu constraints were no longer as significant as memory constraints, so maxing out RAM on an economy system was outperforming their middle range.
The vendors themselves are IMO far too disorganized to be behind these factors, the death of the desktop/pc is largely about consumers avoiding the results of tactics organized by Intel and Microsoft to maximize their own slices that the vendors got no piece of. The only real exception is clutterware, but even that was probably tolerated and maybe encouraged by Microsoft. They had an interest in obfuscating sources of clean media aside from paying them directly at the time and it also let them claim vendors had sources of income to seek out and later to redirect blame.
My perspective is that the volume is low enough that one reposter or even one blogger greatly influences the average direction of the site.
In that sense, I think someone going in a niche direction with posts could give a niche that interests them (and is not the main perspective of some larger site) a try on this site and have a slight headstart on bringing that niche to the larger sites..
The opposite direction for this site, would be if everything on HN were reposted here or with equal chance.. Then the site/community has no specific direction of its own, and why make comments here that could be made in the larger community with the same general focus?
