The complex numbers are a degree 2 field extension over the real numbers.

The general theorem is that for a field k, and an irreducible (meaning it can't be factored with coefficients in k) polynomial p(x) with coefficients in k, the smallest field containing a root of p(x) and k is a vector space (over k) of dimension deg p(x). The irreducible polynomial corresponding to i is x^2 + 1 = 0.

Similarly, a finite field of order q = p^r can be constructed with an irreducible polynomial of degree r with coefficients in the prime field of order p.
Yeah. It's not really clear what I'm supposed to be doing when I go there. IS it safe to sign up to a random community to try it out or do I need to spin up my own server if I want an un-revocable identity on the network? Can my node be kicked off if I do that?

I really like the idea of federated services like that, but they need to have two separate, clearly explained ways to participate; 1) What to do as a normal user and 2) what to do as an enthusiast running a server.

I also think those federated platforms will have scaling issues. What happens if I end up with some type of feed that includes content spanning 20 different servers of varying (hosting) quality?
I (woman without CS degree) once pitched to an investor and his first question was “Okay, but who’s going to build it for you?”

Um... me? I _built_ it. It already exists and I have users and I said that several times but apparently the idea of me being able to do that on my own was simply too confusing for him to understand. His next question? “Who’d you hire to build it?”

facepalm
Me too!! The only thing I wish Miniflux did is newsletters.

The only thing I learnt is that 'pantry' means something different in America.. what we call a 'food bank' (AIUI, difference from 'soup kitchen' being handing out ingredients rather than hot meals) by the sounds of it?

In the UK a pantry is a small room/large cupboard used for cool but not refrigerated storage; so I thought this was going to be a sort of 'asset management system' somehow specifically good for shelf-stable foodstuffs.
User Onboarding Teardowns
A bit of a tangent, there was a notorious reddit thread a long time ago with a comment by someone supposedly in the MMO industry [1] that echoes your point about content:

> Art is one of the biggest expenses in a commercially-produced MMO. There's a LOT of it, it's time intensive to create, and it has to be turned around fast

That thread mostly focused on how unrealistic it is for one person to develop an MMO by themselves, which is not exactly the case here. But it gives a bit of a taste as to why MMORPG is one of the most challenging game genres to succeed with. "Half of all MMOs commercially developed never release; half the survivors immediately fail", and the remaining successes almost all have staggeringly huge amounts of art & lore like you mentioned.

YC provides seed money. No one should rely on YC for due diligence.
This is one of the reasons I hope wearing masks in public becomes a permanent thing. I don't want anyone to know whether I am smiling or not.
i hope that any of that has any bearing on engineering practice in our lifetimes.
Game Programming: Optimization Technique Slicing
Yes, I think everyone would agree that OCaml has gone from competing with the predominant high-level language of 1996 (C) to the predominant languages of today (definitely not C).

Another factor is that creating a language (Rust, Go etc.) from scratch lets you have nice unified tooling to an extent that is probably just not possible with languages with baggage. So I doubt OCaml will ever manage to be quite as seamless as those, but IMO it's already gone from significantly worse tooling than e.g. Python/Java to significantly better, and is still improving all the time!
Why are we so hung up on keeping texts? (I'm guilty of this hang-up too.) I didn't archive my AIM messages. I don't record my phone conversations.

Frontier is getting sued by the FTC and a bunch of states for lying about the internet speeds they provide, so hopefully the other ISPs will be similarly held responsible too.. It might take years, though.
Speaking of room heater, I remembered when I was studying on control theory in university and learned PID, I was thinking "this thing is so simple and yet so effective, it gotta be everywhere!".

It's a little bit disappointing when I later realized that most of heater/air conditioner basically just use on/off control with a deadband. I guess the limiting factor here isn't the controller but the actuator part, but still a let-down to see them being so primitive.
the point is, he or his fund can also get cheap loans when rates are historic low by land and win twice by inflation
As far as I can see, the court is not doing here anything else than interpreting the law. Literally, the whole ruling is explaining pieces of the law step by step.

> The objects of the EPBC Act include providing for the protection of the environment, especially those aspects of the environment that are matters of “national environmental significance”: s 3(1)(a). Section 3(1)(b) states that a further object is the promotion of “ecologically sustainable development” through the conservation and “ecologically sustainable use” of natural resources.

> The following principles are principles of ecologically sustainable development:

> (c) the principle of inter-generational equity—that the present generation should ensure that the health, diversity and productivity of the environment is maintained or enhanced for the benefit of future generations;
And intriguingly, one can also say that the phenomena of start-up is perhaps a branching-out of 60s' hippie movement (partially inspired by books such as The Whole Earth Catalog which is not only spiritual-ish but leans more towards pragmatism) where instead of going all anti-capitalism and trying to be self-sustainable from the ground-up and detach itself from the economy (which eventually always ran into problems cuz then it became a micro-economy itself, which was the very thing it tried to transcend), start-ups aims to be self-sustainable in the existing econcomy while detaching itself from the cooperate cultures.
> Games are not about content, they're about multiplayer experience.

The amazing success and critical acclaim of single player games such as Horizon Zero Dawn, the Metal Gear Solid series and the Deus Ex series, among others, might make you reconsider your position on that.
It's a random number in front of physical measurement, unrelated to anything from reality.

Just because all of the marketing departments choose to participate in this particular bs doesn't mean it's not pure marketing bs. That just means it's industry standard marketing bs.
I agree!

I've often gotten sidetracked in design software so many times when all I needed to do was add a small update to the UI.

The process goes something like...
1. Have an idea or requirement to add a small tweak or feature.
2. Find the original design file.
3. Figure out how the file is constructed.
4. Get frustrated because I notice unrelated inconsistencies.
5. Forget what I was originally doing.
6. Realize hours have past and I haven't accomplished the simple task yet.

I am creating NextUX to make updates to designs faster and easier for more people.

My process now looks like...
1. Have an idea or requirement to add a small tweak or feature.
2. Take screenshot(s), update the design, and add comments.
3. Share the iteration with the team in Trello or Jira.

I hope NextUX enables non-designers to incorporate more visuals with their writing. It doesn't have to be pretty, but adding mockups to a spec doc, long email, or jira issue makes it so more obvious what is being proposed.
He says it's his opinion, but then states that the language shouldn't have tagged version 1.0 without it, and that people should not advertise julia because it's such a important feature.

I totally get that there are workflows that Julia is inappropriate for, but when someone says that a tool shouldn't be released because it doesn't target their workflow, I really don't know what to call that other than blindingly self centred.
Yeah, I understand that. But I mean as members of the military who are trained and indoctrinated into OPSEC and information handling practices, I would expect them to have made a better decision.
> We know that scientism definitely is, and it's emerging these days.

I agree, and I tried to make the distinction between that and the science that produces results. Whether science also requires faith, would be a lengthy tangent. I don't necessarily disagree with that, it would depend on pinning down what exactly we mean by faith, which I think was beyond this thread. Good discussion though.
Genuine question; is this any good? Is there artistic merit to this work? Seems like an absolute word-salad, but would love to be told otherwise
Very eager to see how your app works when it opens up to the public. Are there ways to provide assurances for your end-to-end encryption which may be digested by experts?

At least in the German ruling of the constitutional court they could refere to Article 20a of the German constitution

Art20a, Roughly translated:
The state, in responsibility for future generations, protects the natural means of subsistence and the Animals in the constitutional order by use of legislative, excecutive and judiciary measures.

Of course this doesn't say verbatim to protect the climate but I think this is enough legislative basis to rule dangerous negligence on the matter of climate change unconstitutional.
Price increases happen as a result of supply shortages. E.g. demand exceeds supply, reducing availability of the goods.

If the supply chain is not elastic enough to increase production quickly, prices will likely rise. See: any chart of Supply/Demand, that demonstrates the relationship.

But saying price increases are due to shortages should not alleviate inflation concerns, unless there are specific supply side reasons for the shortage. Prices will only really tend to increase when producers can't meet demand, and can't ratchet up production quickly. Otherwise they're leaving money on the table by having empty shelves of their below market priced goods.

E.g. if the chip shortage is caused by a natural disaster: supply side issue. If the chip shortage is caused by increased demand: demand side issue (which manifests as supply shortage).

It's very important to distinguish the reason for the shortage to get a better sense of what's going on.

In some cases it's just backlogged things due to covid, in others it's increased personal consumption draining inventory and leading to demand induced shortages.

Inflation doesn't manifest uniformly. You'll see prices of some subset of goods increase, now that company has more money and spends that money etc. It's highly related to velocity of money
I took this approach many years ago to get them into a pdf. Was able to with minimal headache iirc.
Not necessarily, the article mentions that YC allegedly never even vetted the project:

> According to Upton, a senior employee at Y Combinator claims that Bellack has a friend in the accelerator who helped greenlight DreamWorld without the appropriate due diligence. "Originally, I thought this was a bit of a joke, but they called me and validated all their information and their sources. This person is actually higher up than just investing," he says. "[DreamWorld] wasn't vetted. They apparently had nothing to show on demo day, and they were still allowed through."
> Very often Western people criticize Russians for being too gloomy and unfriendly because we never smile

WTF? I'm very often around Russian and other Slav people and many of them smile plenty.

> In Western culture, and especially in the United States, the smile is an indication of well-being ... In Russian culture the smile is identified with laughter. Russians do not smile unless something funny happens and provides a reason for laughter.

Massive over-generalization. Local culture, personality and personal life background induce much more variability in tendency to smile than whether you're Russian/Slav or not.

Also, the author seems to lump the US and Europe together, something I also frown upon.

Bottom line: I am not smiling at this article.
DOJ indicted ham-sandwich Russians, then later retreated. Only process crimes charged (lying, interfering). Buying ads on social media isn't illegal, and the amount was de minimus (< $30k). FARA crimes were reverse-engineered, selectively prosecuted, and didn't related to Russia in any way. Everything about these headlines is an utter farce.
yes it is really bad, the UIs for PMs was better 10 years ago, thinking about ICQ, Adium, MSN Messenger and the like. You could export history as file and easily scroll and search them

Yea, I’ve found it interesting reading about YC companies from this batch that include:

- A scam MMO

- Terminal autocomplete as a service

- A Splitwise clone

- An app that puts your next meeting in your menu bar (for $10/month!)

YC gets 5K+ applications/cycle, accepts 1-3%, so they rejected 4500+ companies for these?
Thanks. That makes sense. But I didn’t feel like deleting anything. Just my wife and I on the iCloud storage and there’s plenty of it at present. My photo collection that I’ve been cleaning up is a bigger offender right now than messages. Damn cats doing cute things.
I don't buy the theory that the Web PKI or some equivalent is "unnecessary for non-Web things". If anything I think there have been a few places where there's a nasty security gap because somebody didn't just stuff the Web PKI in there, even though it wasn't necessarily a perfect fit, because what we got instead was nothing ie no security.

An example of that first: Does your phone try to connect to SomeBrand WiFi networks? How does it know if this is a "real" SomeBrand WiFi network? It doesn't. In some scenarios this means you leak valid credentials for the "real" SomeBrand to bad guys. In most cases you at least leak identity information. That's not great news. If the WiFi network was named example.com the WiFi AP could of course present a certificate for example.com, leveraging the Web PKI.

Now, there are people who want to do QUIC without TLS, mostly what they want to do is NOISE. Like this: https://www.cryptologie.net/article/467/quic-noise-nquic/ But again, I think something like SSH is the exception and the Web PKI is more applicable to most uses for QUIC.
And who pray tell decides its value? The central planning committee?

I know what building an MMO is like, having worked on one 10 years ago that was already 10 years old and still exists today (small audience though).

Building something like these people are talking about requires more $ than a Marvel superhero movie to get anywhere. We could manage about 100 simultaneous players visible to each other in a reasonable time but no more; the internet is not fast enough to manage more than that many "people" with anything resembling real behavior, even then its hard to maintain the illusion of fluidity with the random latency of so many streams using prediction. Supporting millions of users like these people claim is fantasy even if you only saw a handful. Maintaining state in a single world at that volume is impossible with real people (you can fake a lot of "AI" characters but not actual players). There is reason why most MMO and similar games limit the number of players, or like Eve throttle the game time and slow everything down if too many ships appear in the same place (not possible in a "on ground" sort of world).

Also building something of this magnitude and even getting it to do even a small subset of what they want requires people with lots of experience, as this is highly complex and specialized programming, not to mention an enormous amount of art creation, lighting, audio, story and other content, unless you go the No Man's Sky route and generate everything. But they don't support huge numbers of"local" players either.
I feel like it's a little less responsive to movement than the real game.

I live in a concrete house. Our phones don't receive wireless signals inside the house and we can't get wife on any floor except the main one where the router is. At least for houses like mine, cat-6 will be around for the foreseeable future.
"What are you doing to help solve that problem?"
what does that mean 'going dead'? like you even said, other articles from 'bellingcat' seem fine, so just wait for it to be upvoted if it's actually interesting
Probably not the kind of answer you're looking for, but networking appliances (routers, switches, firewalls) essentially used to be "unikernels" in the early 90ies, particularly the original Cisco IOS. Which is also a great example that blurs the lines between embedded systems and unikernels…

That said, no modern router is a "unikernel" anymore, and the low end switches fall more into the embedded systems category.

(btw: out of curiosity, how would HN differentiate between an embedded system/RTOS and an unikernel?)
This is very rare in MMOs. Most are not really sandboxes but theme parks, where most multiplayer is through interacting with the content cooperatively.

The more I see those small graphical OSes like this one, Kolibri, etc. the more I wish they were ported (or better conceived from the beginning) to be run on ARM systems. Those small cheap boards with video output would find the best possible companion when bare metal programming is too hard and a full fledged Linux distro would be overkill. Give me a compiler, then libraries for gpio and hardware, GUI, low level networking, etc. and I can choose between a huge load of cheap boards to build a lab instrument panel, my new home IoT dashboard, a portable communication device, a music synthesizer, etc. It looks to me as those two worlds are in need of each other but they don't know that yet.
Although this looks like quite an interesting article, I gave up reading it because of the awful graphs. Surely people eager to analyse this issue can read a logarithmic scale, which would provide valuable clarity and context.

I'm familiar with the issues in the article and understand the desire hook reader's attention by pointing out income disparities as dramatically as possible. Still, once a reader is engaged then a more technical presentation allows them to get more value from the article and better equips them to discuss or debate the issue.

> Very eager to see how your app works when it opens up to the public. Are there ways to provide assurances for your end-to-end encryption which may be digested by experts?

We recommend using a simple MITM proxy or a firewall app like Little Snitch / LuLu to inspect the network traffic.

Yes – there's a peer-to-peer connection between the Windows and Mac devices.
From the first paragraph:
"So wild, a Bethesda, Maryland, resident recently included in her written offer “a pledge to name her first-born child after the seller,” according to the CEO of the realty site Redfin. So wild, she did not get the house. "

I understand that the author is trying to say that the housing market is so bananas that even offering your first born didn't get them the house, but on what planet would people want that? If someone tried to offer me naming their child after me just to purchase my home, I would immediately decline, or at least beg they drop that condition. Strange...
These decisions can easily be legislated either way completely invaliding most "judicial overreach" after the fact. It's just the legislation branch in a lot of countries are quite happy to not be involved in these kind of big decisions.

Likely because each iMessage receiving device has a private key to decrypt the messages, and senders encrypt the iMessage against all the keys in your key bag.

To access iCloud and or services you also need to have a device security key that is tied to genuine hardware.
It's the same in Russian actually. You're saying "how are you" ("как дела") after "hello" ("привет"), but you're not really expecting any meaningful answer other than "I'm OK" ("нормально") or "I'm fine" ("отлично").

But it might be one way to start a conversation when you want to tell something you don't like. Like "How are you? I'll live. What happened? ...". But it's more of closed friends conversation when you can feel OK sharing your burdens with other person. I guess, similar thing could happen in US?
