Ask HN: Can someone recommend a game for a programming competition?
I'm going to make a competition for my company's developers so that we can explore other problem domains with programming. I'm thinking about something simple, where one can make a playable AI without too much effort. Can anyone recommend such game? Can you also recommend a server software to host this competition?
That should be about 360MB of uncompressed data (1024x768x88x4 bytes) which should fit into the memory of most IGPs, which generally reserve 1 or 2 GB. Compositing 4 images at once should be something that even a very old GPU should have no problems with, even at 4K resolution. Windows Desktop Composition probably does a lot more work.

Still this indeed gets my laptop's fans spinning in both Chrome and Firefox. I wonder why that is... I don't think you can do a lot wrong code wise here. Maybe the composition takes a software path, but why?
Check out the materialic app on android. Themes (solarized and others), the possibility to download comments for offline reading and more. It is the app use the most, yes i'm an infovore.
Worldbox had been in the market for 8 years. They stole the code (given the cloned app's appid is called Worldbox) and rejigged the sprites. Then tried to trademark "Worldbox" (which isn't the name of their game) with the plan to then change name and kick Worldbox off the store.
For one, they didn't invent the platform they're using for the purpose of the conference so they're paying per user. I believe they're using https://gather.town/pricing

If that's not a satisfying answer, chalk it up to tradition. The streams are provided free for an unlimited number of users. Maybe they only want to deal with the customer service side of a few thousand attendees.
Absolutely. I've maintained a fork of an abandoned OSS project mainly because I needed it for myself and it was easy to just do it on GitHub.
Turns out some folks noticed, starred the repo, used the code and someone opened a „Thank you” - Issue earlier this year.
That was a main reason for me to actually publish the code on NPM, work towards a stable version and write some documentation at some point.

On the whole it seems like it doesn’t have that far to go
This is one of those obvious things that people have a blockheaded aversion towards. In every job I’ve consulted on, there has been a component where pagination is the bottleneck. And it’s rarely where pagination could be useful (like a static list of products). I typically see it when someone builds an aggregating (and aggravating) microservice that pulls all of the data from another service; that blocks the entire database.

Perhaps it’s the world of ‘Django developers’ I find myself in. But the fact this simple design pattern reaches the front page of Hackernews worries me.

I’ve personally had backend developers give confused looks and diatribes about simplicity when I’ve suggested this approach. Frontend developers frequently give the greatest resistance, which I think is because they most often act in concert with product managers who are welded to certain UX idioms that they chose without fully imagining the engineering consequences of.

One approach which I try to push people towards is fetching a big list (N≈5000) and paginating it however the UX designer wants. The response of the big list should be sparse, that is without including additional fields that aren’t displayed by the front end (and fetching more data when the user navigates). You’ll frequently get puzzled looks suggesting this, but benchmarks will usually show that fetching 5000 rows and a small number of columns takes a few milliseconds, and can be serialised into 150kb. On balance it ends up being faster: as you’ll get fewer network requests; fewer round trips to the database; fewer fetches; and less time spend serialising (which is a major bottleneck itself that Python developers ignore).

Yeah that part should be updated. It is still valuable in that it specifies that there should be some sort of minimum standards for secure data transfer. Even what is specified there is way better than nothing.
> There is a period of time when someone is already an expert but not yet committed to any particular belief. This is an excellent time to listen to their opinions. Unfortunately, this period is usually quite short for most people.

Is there? Or is this an unfalsifiable classification that people one agrees with can be put in, and people who one doesn't agree with can be pushed out of?

The idea that opinions have no relation to expertise is a general argument against expertise. The magic period during which people have expertise but don't have opinions seems related to that magic period for journalists when they understand all of the facts about a story accurately but have no opinion about what is true and what is not true.
Seeing the Magento market share brought sweet nostalgia from the 2010s era. For a brief period of time it was all the rage in PHP commerce. It was seen as more professional than a WooCommerce setup (performance and bugs aside, I guess).

Magento 2 released and it had a better aesthetic, but it was more of the same broken ideas no one wanted to work with. Why the team went with a fresh take on the old XML-based configuration is beyond me.

Clients I worked with passed on Magento 2. Somewhere in here there is a lesson I can't articulate :-)
I'm building buyforlife.com, a platform to overcome cheap products and keep corporations accountable - the Rotten Tomatoes for products.

Have you ever been annoyed about an Amazon review saying "Package arrived flawless after one day, 5 stars"?

I want to change the way people review products. I'm now introducing "Recurring Reviews". After every year, the reviewer will receive an automatic reminder to assess the condition of the product and if the reviewer is still happy with it. This is how we can follow the whole lifecycle of a product.
It is not like a comment on HN. The Guardian editorial staff wouldn't agree to publish it (and pay the author) if they didn't agree with it on some level.
The point of a microbenchmark is to determine how much a single aspect impacts the performance.

Yes, everything impacts performance. But if you're trying to optimise a hot code path, you want to try minimising the unnecessary overheads.
I also agree that plastic is probably bad, but it's everywhere though and I've kind of resigned myself to the fact that it's become unavoidable.

With respect to the article, it's an opinion piece and clearly marked as such. I'm not sure if this is a difference between US and UK papers, but in papers that still try to have some journalistic integrity in the UK there is, by convention, a difference between articles marked as 'Opinion' and news articles. The writers of opinion pieces are invited to submit articles on a one-off basis and are not necessarily journalists, they can be anyone and the articles they write are expected to hold an opinion so when you read one the understanding is that it will be biased towards a particular viewpoint. So the Guardian frequently has opinion pieces written by politicians (generally centrist but from the left and right of politics), activists, scientists, etc. These opinion pieces typically lean leftish on average, because its The Guardian, but individually they are not always left leaning.

Do newspapers from other countries have a similar convention?
There's NIMBYism in the UK too. My local Tory MP managed to kill the offshore wind farm navitus bay you would have been barely able to see (12-15 miles offshore).

Reference : https://static01.nyt.com/images/2008/10/04/nyregion/wind600....

He did it by collecting signatures from local business owners complaining it would "ruin the view".

I think he may have been lobbying on behalf of incumbent utilities. He clearly wasn't doing this because of a few specks appearing on the horizon, but exploiting knee jerk NIMBYism over the view was how he got the project canceled.

Ok so you are saying not only are there implicit super instructions via macro op fusion there are also variable length instructions in there too? Ok, I'm not a RISC-V expert but damn that kind of ruins even the last tiny shred of its original value proposition of being simple. Sure the core instruction set is easy but once you add extensions it's just plain ugly.
I went through the signup flow, and the only information it asked me that was ever verified was my phone number.
> Should we randomly hire one?

If the additional interviewing time doesn't produce real improvement in outcomes over random hiring, then yes, don't waste the interviewees’ time and time the form is paying you for doing it.
Thanks for pointing this out! Great suggestion, I will try it out.
The UK is giving up on its industrial production capabilities. I saw a National Grid document not too long ago talking about how their infrastructure plans involve downscaling the grid capacity up North as it comes up for replacement, including outright removing lines, because it was built to support industrt that no longer exists in the country. In general, there's just not the political will to actually make things here, and the press tends to push the narrative that anyone who thinks we should is stuck in the past.

More like the people who love to tell you they're "child-free" or "don't own a TV/smartphone" (or a thousand pro-gun bumper stickers or open-source laptop stickers or punk rock patches . . .

Virtue signaling is like tryinf to help people see in the dark by shining the flashlight you're carrying in their eyes.
> If a few more hours of interviews can avoid a bad hire

Can it, though?

I'm sure it can increase the manager subjective feeling of confidence, but does it verifiably, objectively produce better results?

> When weighing people's opinions, expertise should be rewarded but commitment should be penalized.

This is straight paranoia, unless you plan on only talking to people about their job or topics that don’t interest them.

You’re clearly too committed to your opinion here.

> There is a period of time when someone is already an expert but not yet committed to any particular belief.

Experts without opinions? It sounds like you’re just talking about a toaster. Toasters have no opinions about you when you set the shade to dark, like a monster

It's trended downward because of the basic economics of the "peak oil" argument - it has become more scarce and thus more expensive to extract.

The "more electricity" point is a red herring. Cost per kwh is all that matters.

That's like pointing to AM radio being around longer saying it produced more hours of audio and then trying to use that as a basis for it being of superior quality. It's just older.

The bicycle argument is also a total misunderstanding of the vast technical superiority of things like modern solar.

The aptera and light-year one automobiles for instance, both due next year, will feature solar panels, that in sunny climates, will charge a vehicle more miles than an average daily commute.

This means that in typical use, the owner will never need to plug in or otherwise fuel up the vehicle, at all.

For a WFHer like myself it means I effectively will always hop in with a "full tank". I'm excited and you should be too.

These are the 1.0 version of the cars. Wait until the 5th or 10th year.

In 2030, a 1,500 or 2,000 mile range vehicle that fueled itself merely by sitting outside is what I'll be driving. You can continue going to the gas station and paying $10-20/gallon if you wish. Have fun.

There's significant revolutions in energy coming in the 2020s. Such as partially transparent photovoltaics that transition window UV exposure with the sunlight so you get a pleasant adaptive window coating that also powers your home.

We're on the road to effectively unmetered energy. We are doimg much better than coal now. Let's keep moving
I reached the same conclusion about stackoverflow.

Penalized is just the converse of rewarded. Use negatively-weighted instead if the language is the point that trips you up, but the person who writes “Frankly, I was shaken to the core by what was exposed, yet I understood why the stakes were sky high for those seeking to hide the truth. Why it was a fight to the death to keep a lid on their secrets?” does get those words negatively-weighted in my accounting.

That negative score is added to the positive score from the expertise part of the author when I determine how much credence to give their argument.

The show ended before a large swath of HN's demographic was born. I watched it as it aired and barely remember any of it. I wouldn't know that was a Seinfeld reference if no one said anything.
I do like the user interface of WooCommerce, it fits quite nice into WordPress. What I don't like about WooCommerce is that they don't care about backwards-compatibility. WordPress Core is very much into backwards-compatibility, and I think plugins and themes should follow that idea. I do wish something better then WooCommerce would show up for WordPress.

And another thing, that I personally don't have much of a stake in, a lot of WooCommerce addon plugins are of dubious quality. Following the Wordfence blog about security issues in plugins, there are often Woo plugins that have quite some big issues, like unauthenticated SQL attack or similar. As a hacker you don't even have to go to the trouble of multi-staging several security issues to get in, 1 of these is enough.
What Is the Color of the Universe?
I've noticed the same. Maybe all of this YouTube tinkering will help revitalize the hobby.
Yes, the alternative pitch would presumably be that EU standards (which the agreement is (I suspect) copying for now) aren't being updated fast enough because of the bureaucracy of 27 countries slowing things down, even for uncontroversial changes, and on its own the UK could move more quickly.
I have the same experience. Stack Overflow is not great when you try to achive something novel or do something new from scratch.
For reference, a great intro to Lean for programmer-types without an academic maths background is Kevin Buzzard’s Natural Number Game: https://wwwf.imperial.ac.uk/~buzzard/xena/natural_number_gam...

Buzzard’s wider Xena project is formalizing a huge chunk of the undergraduate-level math curriculum into a “standard library” of math, written in Lean.
No, because you don’t need to render at full resolution where you’re not looking. That’s the appeal of foveated rendering, you just render say, a tiny 1080p region where you’re currently looking, and render the rest also at 1080p but stretched out over your entire FOV, and with fast enough frame rate and eye tracking, plus a decent blending algorithm, it will be unnoticeable.

But looking at the whole is not nearly enough. I don't want my electricity turned off during winter.
There's already a planned 500km interconnector between Ireland and France[1], which avoids Brexit related risks. Since wind power is growing in importance in Ireland, it's a great chance to make the EU grid greener, and build out the idea of the EU super grid[2] concept.

Ireland also has enormous offshore wind potential off the Atlantic coast, which could be built out and the energy exported to mainland Europe.

However, let's hope that the UK can agree to a deal to fully develop the potential of the Dogger Bank project[3, 4] (collaboration between the British, Dutch, Germans and Danes to build the largest offshore wind project in the world).

Another project I'd love to see is Iceland's geothermal energy piped through Ireland or the UK to mainland Europe[5], supplying crucial baseload energy to the UK, perhaps even to mainland Europe.

Defining activists as hopelessly biased due to their commitment is nothing but blanket immunity for corruption. The corrupt have no commitments to anyone but themselves.

Becoming passionate about something is generally a result of the interpretation of facts, not the cause. It's very difficult to become passionate about plastic pollution without any knowledge of plastic pollution. The only people that can maintain this fantasy libertarian opinion without enthusiasm are people who support plastic pollution because it makes them money, and pay people to come up with arguments to continue doing it - hence all people without a financial stake are hopelessly biased activists.

If they're not making money, what could they possibly be getting out of it? They're obviously insane and feeding their own egos through heroism, and therefore can't be believed.
That is simple. Journalism becomes another super-optimized activity.

"Journalists" today typically want to expend as little effort to get as much results the reader be damned. The results are defined by your output in the views you can generate per month and this means you generally want to write a lot of articles each to be well received... by Google algorithm. You probably also want people to spend a little bit reading the article and hopefully scroll further than the first page.

Douglas Adams, Salmon of Doubt:

> “Incidentally, am I alone in finding the expression ‘it turns out’ to be incredibly useful? It allows you to make swift, succinct, and authoritative connections between otherwise randomly unconnected statements without the trouble of explaining what your source or authority actually is. It’s great. It’s hugely better than its predecessors ‘I read somewhere that...’ or the craven ‘they say that...’ because it suggests not only that whatever flimsy bit of urban mythology you are passing on is actually based on brand new, ground breaking research, but that it’s research in which you yourself were intimately involved. But again, with no actual authority anywhere in sight.”
That's not an accurate comparison. You are then using that 20% to power grow lights for photosynthesis. How efficient is photosynthesis using grow lights? Even if it's twice as efficient, you're then looking at 4% of 20% which is 0.8%.

Sure, this can be used used land not suitable for agriculture. I only see this really being helpful in cities that have old industrial buildings that are sitting vacant (reuse existing infrastructure and reduce transportation).
But isnt that the contrary of what Christensen postulates, starting at non-competitive down-market nieche and work upwards?

I'm rather bearish on Tesla for various reasons. I also believe current stock prices for Tesla and Amazon are mainly driven by general uncertainty and too much liquid cash with nowhere to go.

That being said, vertical farming doesn't realy solve any problems, food nd water are distribution and not availability problems. None of which are solved by vertical farming. Obviously that doesn't prevent people from raising a shit load of VC money. If anything, the wetern world is producing too much food, incl. meat, in hyper industrialized farms already.

1. I didn't say they were wrong, I said facts are being misinterpreted. That means that even if we assume the facts in the article are true, the interpretation of those facts isn't being done objectively.
2. If you are going to talk quantitative, please start with a concrete definition of the KPI and how you calculate utility and cost.

If you are looking for concrete examples of how you are being manipulated by the article, then to name just a few example:

- The article drops analytical rigor just at the exact moment when it benefits their narrative. For example, the 2020 goal of the initiative was a projection based on certain assumptions. To say if the project has failed or not according to those projections, the assumptions must hold. Funnily enough the article doesn't list those assumptions anywhere or address whether those assumption still hold true, or even if they were valid to begin with.

- The article uses language to imply malice, where there is none. For example: "Moreover, freedom of choice is restricted: in AGRA projects in Kenya, small-scale farmers are not allowed to decide for themselves which corn seed they plant and which fertilizers and pesticides they use on their fields." Gasp, horror. An investor wants you to follow their rules. How dare they. Jacobin should be on the barricades that VCs don't allow you to spend their money on a new Porsche, because that limits your startups freedom of choice!

- The article talks about agroecology as if it's as of now a viable alternative. Unless there's tons of investor capital lined up behind it, it really isn't. In fact, these aren't even comparable things.
I'm not sure why you say it's a "quite safe" assumption that most games are written in C#. Unity's beginner-friendliness gives it a disproportionate presence online, while the vast majority of AAA games are still solidly C++.

If we eliminate all games with less than 1000 sales or something, I think it would be a very low confidence estimate.
