It's worth noting that there's also gallium nitride to consider and while it isn't as good as silicon carbide in high temperature applications or areas needing higher thermal conductivity it's better than silicon carbide as far as breakdown voltage and low resistance are concerned. Maybe eventually we'll see GaN in server power supplies and SiC in VFDs for fans, cooling, and DC infrastructure. There might even be a justification to use SiC solid state transformers to bridge between utility power, generators, battery banks, etc.

It's very important to note that 50% efficiency gains might not be as huge as it sounds given that we're just talking about losses in MOSFETs. This isn't going to be turned into your next CPU or show the same kinds of efficiency gains in logic circuits.
This is awesome and all, but I don't understand how it will support itself? Unlike Matrix which has plenty of money from government contracts (and venture capitalist money, which kinda sucks but whatever), I don't see how a centralised chat platform with video, voice, data rich messages, etc. relying on donations can support a large user base without one day compromising on privacy respecting data collection.

With Matrix, everyone can help share the load by setting up their own homeservers, if they want to. Plus, P2P is going to be part of the protocol at some point with embedded servers in the clients.

So what's the monetisation strategy? I wish they were more upfront about that, even if the answer was "we have no idea yet". And if the plan is not to monetise, an answer as to how a centralised server with high demand will keep up with capacity would be appreciated.

From the TOC, it looks like an elementary algebra book.

Students usually don't see rigorous construction of integers and rationals till classes titled something to the effect of "intro to proofs 101", "intro to discrete analysis", "abstract algebra 101", "elementary general algebra", "elementary set theory", "basics of elementary number theory"... And the construction of reals would have to wait till something like "elementary real analysis 101".

Usually, after elementary algebra come 3 semesters of calculus. Subject as vague and, uhh, as un-mathematical as it contains neither concrete definitions(other than the one for derivative), nor any theorems. Nothing substantial to grasp at when drowning.

Traditionally, actual learnable definition-lemma-theorem-corollary-examples style math starts after the calculus sequence. So the audience for the linked book is at least 2 classes removed from the time they get to see number construction.

While elementary algebra is both useful and unavoidable, I don't think the same about the calculus. IMHO, the latter is just a waste of time.

The sequence elementary algebra -> intro to math proofs -> elementary real analysis -> Lebesgue Integral by way of Daniell-Riesz -> complex analysis -> non-Euclidean/abstract topology -> measure theory -> probability theory -> differential geometry would give anyone world- class education into the nature of functions which the calculus sequence is kind-sorta supposed to give you a tiny and very distant taste of.
In case of this law passing they will raise prices to cover costs for supporting old hardware. But I, perosnally change phones every 2 years becuse I like new techology and do not want to pay the price for supporting obsolte hardware which I do not use. Proposed law should balance benefits of people who want to use old hardware vs. ones who one to upgrade often.
This is a great list. I also use sops because it has symmetric key support for a great many systems, allowing me to use gpg and aws kms for one set of secrets.
Thanks, omarhaneef. People like you (many years later) are why I did this in the first place. :-)
Not exactly true. You can formally construct the set of real numbers with set theory and then say a number is an element of that set

Looking at https://www.travelsafe-abroad.com/united-states/savannah/

So... How Safe Is Savannah Really?
Savannah is a reasonably unsafe city.
The crime index ranges from medium to high.
The main problems here are robberies and assaults, car theft and theft, vandalism, violent crime, and drug problems.
Nevertheless, the historic Savannah district is entirely safe for exploring the area day and night.
Better to be in a company than one.
Outside the historical site, district crime is more common.
When studying a historical area, remember that this is a tourist area, and there will always be those who hunt tourists – be careful, but especially at night.
One still needs to follow the dictates of common sense to avoid being victimized.
Don’t walk around alone at night, particularly in unfamiliar neighborhoods.
Lock vehicles and keep valuables out of sight.
For cars, perhaps you need to be especially careful – the number of car thefts and hacks is enormous.
Be sure to close the car and park in a guarded parking lot to avoid problems.
Never leave anything in the car, not even trinkets.
Do not get involved in any relationship with drug dealers; drugs are illegal here. Nevertheless, there are many who wish to offer or sell them to you.
Keep an eye on your drink at the bar – there have been times when strangers added opiates to rob a victim.
Lead doesn't explain it, warmongering is something that has been high since ancient times, but airborne lead dates to the 20th century.
There are an assortment of different tips or practices I've found useful over the years but it's hard to beat exercise and cognitive behavioral therapy.

I'm embarrassed to say that for cultural reasons I've never been quite able to actually go talk with a therapist but at one point I started hearing about some companies keeping performance coaches on staff and realizing that was actually something I was neglecting career wise and life wise.

I'm no expert on the topic or anything. The little bit I know is from a book called Feeling Great written by Dr. David Burns. It's written half as a self help sort of guide aimed at people trying to use the techniques and half as guidance for practitioners on how the techniques actually work.
I'm sure there are more elegant approaches, but I would start like this:

A number is an imaginary (as in made up by humans, not as in complex numbers) object that solves certain equations.
It is not well defined and should not be used as basis for other definitions.

"Natural numbers" can be constructed directly and have a well known notation. Integer numbers are used to make the equation "a + x = b" solvable by x for every natural number a and b.

Rational numbers (Q) make the equation "ax = b" solvable by x for any non-zero integer a and b.

The algebraic closure of Q (=: Q*) makes the equation P(x)=0 solvable by x for any polynomial P.

The definition of R is more complex. I guess I would simply say it contains numbers to solve equations like sin(x)=0 by x.

This makes it very clear that -3 or 0 apples don't exist. These numbers just have the purpose to solve equations which makes them handy if you want to compute stuff.
Hi Kenny,

The motivations that you've talked about, learning or money and generating users, are these the only motivations when undertaking a side project? When thinking about a side project would you think about other motivations as well?

Is there room for undertaking a side project where the aim isn't learning or money and users but instead there is a motivation to improve how the world is, making lives better for people?

"Good" is such a subjective term. Even the worst totalitarian governments are good for some percentage of the population. Even the best democratic ones have people who are struggling against the system and would regard it as evil.

I live in New Zealand and there are people driving around thinking we are a communist country and feeling oppressed by government. They express as much through the signs and stickers all over their vehicles.

I wish that good and evil existed in a measurable way but I fear that we live in a world of grey and everyone sees the shades differently from their different perspectives.
As a creator with some dead project(s) I feel horrified when I think how many hours I “wasted” on them.

But then again, I had to scratch those creative itches, I had to built those useless things, they made me what I’m today, a more experienced, tired and inching closer to a break from software engineering.
You need to revisit Economics 101. High demand -> price rise -> more supply -> price drop. If you set a price ceiling, this will make the shortage worse as the market cannot properly function.
View length. If I watch a whole video then that's positive signal between me and that video (no matter if I actually like the content or not). Netflix gets that as well. I can say I like history documentaries, but Netflix knows I really use their service to watch trashy reality TV shows in the middle of the night - and then they use that information to choose what sort of shows to produce.
not sure what your definition of epicenter is, but the definition i know says it is the point on the earth's surface directly above the focus of the earthquake. so a human could easily be the epicenter since they are primarly found on the surface.

Even in your example there are scenarios it could be worthwhile. What if it’s gas produced in-country and its used as a military fill station? Particularly if it’s always available despite foreign political events. For personal usage maybe it’ll never be worth it, but perhaps it’s worthwhile for other use cases. Solar + batteries might not work if you can’t buy/procur enough batteries, especially for Arctic regions say where days are short.

Or perhaps it’ll become possible to use for recharging electric airplanes in-flight. In that case the ability to “beam” worldwide might offset the cost of ground based grid of towers or ocean barges, etc.

To be clear, I think it’s very unlikely, just not infeasible. Particularly if antennae tech keeps improving.

None that I could find. I didn't know snopes was in the business of captioning at all.
> Companies have spare storage…but it sure as shit ain’t worth it to them. This is the hubris of most crypto projects: they have no real economic grasp of the problems they jump into. Amazon isn’t going to fuck around with Chia for what amounts to literal dust on their balance sheet. Businesses aren’t going to jeopardize their core competency for a couple of bucks. And the average Joe doesn’t actually have external storage space. Spotify, iCloud, Dropbox, etc. It’s all professional miners. Chia is not decentralized.

Which companies will adopt it and which ones won't is probably hard to determine from the outside. It should be a fairly objective evaluation though internally for a company in terms of what hardware the company currently has and what it will cost to farm Chia and what future expected value for Chia may be. Chia has somewhere between 300K - 400K full nodes operating on the network. That is objectively more decentralized than Bitcoin that has somewhere on the order of 40K - 80K full nodes the last time I checked. So I would say Chia is the most decentralized network I currently know of.

> The payoff for the lottery is HUGE. So even though the EV is negative, people still do it. The payoff for Chia is comparatively small. People won’t (and don’t) care.

That will be a function of the price of Chia. As Chia's price increases more and more people will want to get into that lottery. A lot more people will consider farming some plots of Chia if one XCH is worth $50K compared to $250.

Yep, been using FreeBSD on the Desktop since 1996.
I've used Linux for plenty of things, but I tend not to unless I need something thats written specifically for Linux.
There's very little I need Linux itself for.
My issues with Linus were a few design decisions, how stuff gets into the kernel, how the distributions work, how things are poorly tested/etc.

Sadly now that FreeBSD is using ZoL I'm encountering a bunch of problems related to that :(
Well then, can you at least care if she played all of her hands perfectly and won "in spirit"?

And I think its safe to say that when a women is playing against a misogynic douche like this guy seems to be in spades no less, that she actually does want to take as much money from him and crush his ego.
The one-size-fits-all model is the main problem. It's cultural imperialism.

I think it is mostly solved by relative ranking systems and the user having power to block any terms they don't want. You should get content similar to those that have similar preferences to you.

I really hope to be able to report back in about a year or so on ways to better communicate. At first I thought, maybe the best online dialectics is just walls of careful text rather than tweets. Now I try doing that, and I make careless mistakes and I can barely parse a paragraph without losing my train of thought.

The solution I think is explicit structure. Arguments usually form a (for now let's say) DAG, let's present them that way explicitly. Metadata, i.e. human emotion can be annotated onto that - emoji, good or bad vibes? If you can diff that graph even better.

Argument Maps are kind of a non-technological approach to this: https://fbistudies.com/wp-content/uploads/2015/04/20150417_R... really impressed me.

In fact, working in a fully-remote, fairly high information density (finance) company, I think the work of the pioneer cyberneticists (and potentially Soviet ones, not sure on that as I can't speak Russian) could be immensely helpful for modelling and manipulating the spread of information and humanity within a company.
Oh super neat, thanks! If I understood correctly its more like a cation conductor than a specifically proton conductor, but much of the chemistry was beyond me.
If we're talking about "number" in general, yes, it is true that this is an informal term among mathematicians.
I had Pfizer and it still doesn't trouble me that much, I will catch Covid19 anyway, I'm just less likely to end up with a serious case of it or die.

Why people would just immediately attack the vaccine and not discuss the fact that hundreds of millions, eventually billions of will be exposed to way higher levels of spike protein through actual infection is beyond me.

I agree that it's not ideal, but what was the alternatives?

It’s experiencing breaking changes in the name of improving performance and flexibility. This is precisely the reason why you don’t want it in the standard library, because that would have either prevented these improvements from being invented, or fractured the ecosystem between std::base64 and base64 in just your urllib/urllib2/urllib3/requests sort of way.

As it stands, by being external, people can depend on base64 0.11, 0.12, 0.13, &c. and it all works fine, and over time they’ll tend to migrate to the latest version (dealing with the generally minor breaking changes involved) but it doesn’t matter so much.
Well that's exactly the point. GP didn't state whether a private space mission meant achieving orbit or not.

They way it solves censorship is through decentralisation, which solves most of the other problems simply by being free of the issues inherent to abusive centralised social media platforms i.e Facebook... ads, optimising for user attention on shit content, and anything else trying to extract value that is not in the users interest.

However the problem with decentralised platforms is often more to do with marketing for "normals", even if the tech is sound it will not succeed if it is too obscure. If they can make this into an app and get it passed Apple's and Google's gardens, it might have a chance to compete against facebook and twitter.

It is only solid as long as you don't define irrational numbers literally as everything that is not rational.
Depends on how important such events are in the game. Lazy, or just being smart with your limited resources as culling like this isn't cheap.
> You need to revisit Economics 101.

Personal attacks not appreciated here.

> If you set a price ceiling, this will make the shortage worse

No. You may perceive the shortage as worse, but in reality, 100% of the supplies will be going to people who need them, as opposed to 30% sitting unused in hoarders' warehouses not helping anyone. Having 70% of the supplies in the field and 30% sitting in a warehouse, appearing for sale, but outside anyone's budget, is not an efficient use of supplies in an emergency.

If there is a mask shortage, I want every single mask strapped to a face, somewhere, somehow, and zero masks in a warehouse.

If you don't regulate it, it means the rich get essential items while the poor don't. Instead of the people who have the greatest legitimate need for the essential items getting access to them.
Interesting. For anyone else looking for more info (the wiki site linked there doesn't exist, just has the Wiki software's template page): YouTube seems to have a lot of guides to Valentina [1], and this blog post [2] gives some motivation behind why people use it. They say:

> The Forum https://forum.valentina-project.org/ is a great resource. It's active and admins reply quickly.

but unfortunately the forum seems defunct as well. So, it seems the project is still maintained (last commit a month ago), but none of the affiliated sites are.

Main difference is the profits come from work being performed by members of society that can work, in the form of actual problems being solved. The members of society who are working hope this will help perpetuate the cycle by allowing new members of society to work and solve problems when the previous working members are not able to work.
i’ve watched a lot of youtube this year. every day, and i rarely consume any other media at all. Its overtuned to locking you in and i generally agree with OP. I was watching a lot of guitar stuff and at one point that’s literally all it would show me, despite having other interests. i think i appreciated it was a bit lacking when i realized i was regularly clicking into my subscriptions and searching (manually) for new stuff they or related channels may have uploaded — and finding many interesting videos after wards.

Its a hard problem and perhaps im an exception, but if you are searching for new stuff, and finding amd watching it, that’s a miss by the algorithm. Especially if that becomes the main thing you do.

TikTok (or at least my experience with it) is largely focused on 15-second clips, so I'm not sure duration differences are the significant ones. It seems the algorithm's ability to surface engaging content on a per-user basis is more important than anything else.
in this particular example (NYC subway), it is kinda hard to understand how that benefits people outside of the NYC metro area. I live in a much more distressed mid-atlantic city, and NYC already has one of the best public transit systems in the country. why would I be happy about my federal tax dollars subsidizing transit in one of the wealthiest US cities while my local public transit is barely off the ground?
