Show HN: Numari – an original number puzzle for Sudoku lovers
Hi HN,

Numari is a number puzzle I've been working on for a few months that I (finally) completed recently. This game was made with the intention of appealing to those who like games similar to Sudoku.

I actually released this as a native app in 2018 (for both iOS and Android), however the rules were a bit too complicated for the initial release (the game used to allow for diagonal movements). Since the general feedback about the game was positive, and since I was looking for an excuse to play with and learn React, I decided to remake the game as a web app with slightly different rules than the original version.

I hope you enjoy it, and I'd very much love to hear your feedback and suggestions!
I’ve only been to London once and there is really good public transportation. Couldn’t you pick a smaller town outside of London maybe on the end of line for trains or something like that to get a cheaper place? You could then save money I presume and still be within an hour or so of family/friends. I’m in US so a 3-4 hour drive to me is nothing and a short train ride is even less of a deal.

I have a sit/stand desk and 2 monitors plus laptop and am experimenting with 1 monitor and will probably buy a webcam soon since I’d prefer the MacBook to be “docked” for desk space. I’d recommend sit/stand since the lower back will feel it after some time, although you are young.
Modern Georgists extend 'land' to all natural resources. So minerals, water, radio spectrum, and importantly, 'right to pollute' (e.g. CO₂ emissions) would all be included and taxed.

If you create something without using any natural resources, then you shouldn't have to pay any taxes on it — it all belongs to you. Well done! If a large company does it then same — it's good to use less resources, and taxing their use encourages people to use less. But you will still probably want to live somewhere (and eat food grown somewhere, and drink water that fell somewhere), and you pay tax on what you use, instead of the income you generate.

Georgism is about taxing resource consumption, not income.

Many would argue, but what's their qualification? Where's the meta research implied in your comment that supports your view that social science regularly fails to meet contemporaneous standards for epistemological rigor that physical sciences do?

rundll32.exe is just a way of doing FFI from as a command -- there are few different options on UNIX-likr systems for that. The most obvious is ctypes.sh [0].

There are, though, even more sophisticated options than just FFI, like the Witchcraft Compiler Collection [1], which includes among other things an interactive shell.

It's about status. It motivates a good portion of the population. When they gaze into that painting, they appear more intelligent, more discerning, more uniquely human. Not casting judgment on them, because we all do it in different ways.
Using main as entry point might not be the best option, as that way some initialization code is skipped and for instance not even the program arguments will be easily accessible. Instead, using _start from crt1.o should be the better option:

gcc -fPIC -shared -o test test.c -Wl,--entry,_start -D 'PT_INTERP="/lib64/ld-linux-x86-64.so.2"' /usr/lib64/crt1.o

That being said, looking at things from the outside, I tend to think that objects are not stored in a compressed form. It would make many operations much slower.

1. There are APIs to fetch byte ranges from objects. Would that work without decompressing the entire object?

https://docs.aws.amazon.com/whitepapers/latest/s3-optimizing...

2. You can query over multiple objects using SQL either via Athena or S3 Select.

Edit:

Someone has already explained how byte range requests would work.

> You would also likely delete the 'const'

I never type `const` in the first place. I don't find it useful, which was the point of my original comment.

> then either you work on something unusual

In C++, I've been working on game engines, compilers, interpreters and occasionally some reverse engineering. Not sure if that counts as unusual. I'm always thinking about perf, so if I can safely modify something in-place, I usually do.

> or you should learn to do better

I do just fine without `const`, thank you. Maybe you should learn to have a more open mind.
Too easy to blame the apps IMO, although they're certainly making things worse. I went to college just before dating apps became ubiquitous and from my experience hookup culture was as much a thing as it is now, only people would first drink their inhibitions into submission before making bad decisions.

If I had to take a (very uneducated) guess I'd say as a society we're currently experiencing an epidemic of unhappiness, especially amongst young people, and what the article describes is just one of many symptoms.
The issues in this article are no excuse to back peddle or react with fear, if anything I see them as reasons to continue forward, keep the good, address the bad and keep moving.

This read like one long rant from my mother in law that starts with "I'm not racists, but Mexicans..." Except it's June Cleaver saying "I'm a feminist, but she was asking for it in that dress"

Surely it makes no sense to adopt encryption no one but a few individuals of questionable motives understand, to protect against a technology that is a long way from even proven yet. IMHO.

Anything else requires several leaps of faith that should be no where near "in use" encryption - research is of course a very different story, but stories like this are hardly confidence inspiring.

that's ridiculous. Most software is basically a succession of drawLines / drawRect calls with the occasional pixmap.
Arguably one difference between hipchat and slack in 2015 (when I was using hipchat) was slack nailed their design/UX. In turn it influenced the later generation of chat programs (discord, microsoft teams, etc). And they have good marketing.

If you consider the construction used primarily on-site materials, it appears the money largely went into laborer's hands. It's not like the region is teeming with employment opportunities for those folks, and they surely didn't just set fire to their compensation. My guess is it fed and housed a bunch of area families, not a total waste - but sure, the labor could have built something more useful.

Now the area is a national monument and will draw tourism, creating jobs and growing the economy in a desert.
That is really the authors point. These things that the sexual revolution told us were “neutral to positive” and would bring freedom and lasting happiness ended up not being true. The author mentions the studies that have born this out, as well as many peoples experiences the author relates.
I don't know about others, but in my circles very few couples don't have kids because they can't. Most of the time the decision not to have (another) baby is related to external factors such as high and rising costs of doing so.
This is true, but I don't think your point entirely fair either. Zig's design lends itself to writing this style of code. In contrast the usual way(s) C++ is used encourages code that makes these types of optimizations hard/impossible. In practical terms, if you wanted to write fast software, the ergonomics of the language allowing you to use the desired architecture matter a lot.

(Also, you're replying to the primary author of Zig and presenter of that talk, if you weren't aware.)
They bundled their own (forked probably) GEM runtime with it. No Desktop or ability to launch other apps.

And I don't know if they ever bothered providing a standalone version that would work with DR's GEM.

Also not sure why they never ported to the Atari ST. Would have been probably quite trivial.

TimeWorks Publisher also ran under GEM. And looked a lot like Ventura. And existed for the Atari ST as well.

Maybe you are looking in the wrong places?

Figurative painting — pretty much the definition of glorifying humanity - has made a HUGE comeback over the past decade or so, to the point where we art nerds make jokes about it.

There is still a lot of “difficult” art out there, and plenty of IMO anti-humanist work, but the breadth of styles that are taken seriously is greater than it ever was in history.

You don’t have to like everything. There’s plenty out there you probably would like.
Totally agree with you, but not sure the comparison is apt. When I look at Guernica on my phone, I think "Wow, that's cool, I bet it would be so imposing at full size."

When I look at parent's link to Voice of Fire, I think, "Am I getting punked?" Point being that the small version makes me think "this is dumb", but I can appreciate that the scale of the original leaves a totally different impression.
AFAIR "The Dispossed" assumed people will accept radically lower standard of living, if the system itself is "fair" (low inequality). Communism implemented that in pratice (low inequality, but also low standard of living) and people hated it.
How do Electrical Engineering courses in college deal with this? I think differential equations and the Laplace transform is something they learn on the firt semester or year. The dropout rate must be high unless they have found a creative and fun way to teach this stuff.
I should have read more closely. I just get exhausted with these GoDaddy rants since I'm very aware these stories happen with namecheap and gandi and all the other recommendations that come out when we see these threads, but it's not an instant internet point fountain with those brands.
Then it's a bit weird that she dismisses "consent workshops". What's wrong with those? They explore patterns and scripts of social interaction that successfully remove the fiction of plausible deniability from outright predatory behavior, and enable others to recognize it and call it out easily. This is not something that should have obnoxious political connotations, it's just a straightforward improvement.
Does it give you pause at all that this is, historically, a common way of thinking among authoritarians and fascists?
It's a distributed system either way.

Acknowledging that opens up a whole world of already thought through solutions to problems in distributed systems.

If that thing is good, that's good.

Less sarcastically - this initiative was launched to reduce the fuel usage of German citizens because fuel prices are exploding and reserves are running low. Trains are operated electrically and can use alternate energy sources.

So yes - people were using the train more: Either as an alternative to their personal vehicle (for commuting, visiting friends, going shopping), or as an alternative to taking a plane (going on a holiday, even within Germany).
Chlorine-carbon (or halocarbons in general) bonds are somewhat rare in nature. That is not to say they don't exist, but they are a bit unusual. The problem with halocarbons (aside from fluorine, which has its own issues) is they are generally not very reactive, so they can bioaccumulate. But when they do react with biological systems, it tends to be in unwanted and toxic ways.

That said, as a former chemist, I consume sucralose, and I am not worried by it. Unlike most halocarbons, It's very water soluble, so it does not react in the ways the bad halocarbons do.
that’s still a skill I don’t have, do you? this stupid thing is going to outlive us, and maybe anything we’ll ever do

One of the people paying for it said:

> “Over the years I would sometimes compare Michael Heizer’s City project to some of the most important ancient monuments and cities,” Govan said in a statement. “But now I only compare it to itself.”

We can argue the merits of the art itself, but I think we can agree that the self-congratulation is nauseating.
>Yes, they make reading imports across your entire project rather difficult: Suddenly there are multiple ways of referring to the same module. If you ever have to do a project-wide search & replace during a refactoring (because your favorite refactoring tool failed you), this will be hell.

> Moreover, in each file you'll end up with a weird blend of absolute and relative imports, depending on what was shorter or looked nicer to the author at the time. Not nice to look at at all.

it sounds like your project had inconsistent import styles leading to this issue. IMO imports should always be relative and always be one imported symbol per line, they should be sorted and linted [1] that they follow this exact form. you will have no issues with imports, merges, search and replaces, etc. after that.

Does being this rude normally work well for you in society?

> What you've written, though, is a very, very lazy critique of art appreciation.

No it isn't, because I haven't written a critique at all. I shared a fairly simple opinion broadly in response to some people's reactions of some other people's negative reactions to this work.

> You make a real juvenile start just calling it "snobbery,"

The ad hominem here is inappropriate.

> I'm sure Centre Pompidou is objectively "way more interesting" than the Louvre, why does the Louvre even exist? Thanks for clearing that up.

Objectively? How have you read a position of objectivity into my comment? This is a discussion about art, which is inherently subjective.

> What, did you go to Paris once and have a bad time?

I love Paris. I haven't the slightest clue where you got this idea.

> So: why should we--why should anyone--care about your half-arsed opinion? ... and why should I respond?

Good question. Why did you respond?

> therefore people who do understand that thing are, what, somehow insulting you?

No. I have neither said nor implied that. You should try interpreting other people's comments more charitably in future.

> Just shut up. Let people appreciate things and shut up.

These words — and most of your words that precede them — are entirely inappropriate for this forum.

If you would like to attack me personally, I'd be happy to share my personal phone number with you and you can say all of this to my face.
I'm not a journalist.
I'd like to understand your perspective better. Can you give some examples of the strings attached to the help that are a problem? For instance, homeless shelters might have rules like "don't get drunk or high in the shelter". Is that what you're referring to?
It's more that 'wandering off into the wild and doing your own thing until society settles down/it being worth it to try again' was an option.

Now we're at population levels that require some amount of technological complexity to maintain and therefore a certain level of complex organization.
Like all cryptocurrencies, it has a hugely relevant use case, namely speculation without regulations. The fees for anonymous money transfers at huge costs are also tolerable for large scale criminal networks.

Dangerous? Because dangerous means we can avoid it.
The only reason for scientists and engineers (i.e. non-pure-mathematicians) to learn ordinary differential equations is so they can move on to partial differential equations. This is because:

> "Most of the natural laws of physics, such as Maxwell's equations, Newton's law of cooling, the Navier-Stokes equations, Newton's equations of motion, and Schrodinger's equation of quantum mechanics, are stated (or can be) in terms of PDEs, that is these laws describe physical phenomena by relating space and time derivatives. Derivatives occur in these equations because the derivatives represent natural things (like velocity, acceleration, force, friction, flux, current). Hence, we have equations relating partial derivatives of some unknown quantity that we would like to find."

For the vast majority of people working with DEs, they'll have two major goals: (1) Take a physical problem they wish to model and construct (formulate) the PDE (the actual mathematical model), and (2) Solve the PDE, taking into account the initial value and boundary conditions.

Going through a introductory course in ODEs is a valuable process because a common method of solving a PDE is reducing it to an ODE. However, with real-world problems, the actual approach will almost always be computational:

> Numerical methods: These methods change a PDE to a system of difference equations that can be solved by means of iterative techniques on a computer; in many cases this is the only technique that will work. In addition to methods that replace PDEs by difference equations, there are other methods that attempt to approximate solutions by polynomial surfaces - spline approximations.

A related common approach are perturbation methods, which transform a nonlinear problem into a series of linear ones that approximate the original nonlinear equation, and to which in turn numerical methods can be applied. Wikipedia has a good writeup:

https://en.wikipedia.org/wiki/Perturbation_theory

Quotes from a very good source: "Partial Differential Equations for Scientists and Engineers, Stanley J. Farnow, 1993, Dover"

Pure mathematicians tend to oppose the introduction of approximate and computational methods early on, but there's no reason they can't be taught side-by-side with the traditional 'exact solutions' material, and it would probably greatly interest and benefit students.
> basically no reason to care about wasting lots of horizontal space

There is, but not obvious: the effect can be seen in Silicon Valley where it takes forevery to get anywhere because you need to drive a long distance to get to your destination because it is so far away.

Long distances make for congestion when cars are the main method of transportation (also: see LA).

Subways (and cyckling) scale a lot better. See Paris/London or Tokyo or Amsterdam/Copenhagen.
There's also a physical limitation in the amount of coastline available for building desal plants.

I actually really like brutalist-style angular concrete, so I think this piece is pretty neat. My only complaint with brutalism in actual buildings is that the entrance is generally hidden.
