Anyone know where it is now?

How long until apple blocks this? They are famous for protecting their walled garden and hostility towards cross platform development tools.

Probably after launch. It’sa good way for developers to build and test apps for VP so they won’t go after it for now.

I can't be the only one who is tired of seeing news media digging at Tesla constantly. No other car manufacture is treated the same way.

Same with Elon. News sites know articles about him bring views so there is a new article edit him every other day. At this point I just don’t care what stupid thing he’s done this week.

I wonder what argument is made that it does have zero carbon emissions. Does the article say? I think by 2023 everyone knows the carbon impact of compute so what could they possibly say as otherwise?

Am I the only one who thinks the added "realities" to Counter-Strike have continually made the game worse? I feel like the simplicity and hard corners of 1.6 made the game fantastic for 5v5 gameplay and more competitive. I enjoy the lack of layers and features.
JamesUtah07 · 2 years ago
I’ve been playing a lot of 1.6 at play-cs.com recently and enjoy it way more than csgo. I think cs source was maybe the sweet spot but I agree that the maps now are too busy and distracting and take away from the gameplay.

Offtopic, but have people had any success maintaining a personal email domain as forwarding to the major email providers?

I have a vanity domain, and used to be able to use GMail to send email as that domain [1], and forward received mail from that domain back to GMail.

But with SPF, DKIM, and DMARC (or something), this has broken and such received email gets marked as spam and/or phishing.

I don't know how to fix the forwarding/receiving flow [2], because GMail will see the message coming from an arbitrary source, but being forwarded by an intermediate (my hosting provider's forwarding email server) which will fail its integrity checks.

I have not been able to understand how to solve this. Clearly, forwarding servers aren't a well-regarded use-case in this new era of verified email flow.

Also, I'm not just talking about GMail. I used to do forwarding for my family who used a variety of providers, so I can't just switch to GMail (via Google Domains) for my entire domain.

[1] GMail still offers that feature, under Settings->Accounts and Import->"Send mail as"

[2] the sending flow is easy: just add gmail's SPF to my own domain's

I have for many years BUT you have to pay Google to make it work. It used to be free but I guess it was abused too much for spam. Now you have to pay for Google workspace and it should work.

It's not just silencers - movies and video games are generally bad at gunshots. For good reasons - if you make them as loud as they ought to be, even to the limits of the recording equipment (since you'd need to go well into the hearing-unsafe territory), they'll drown out everything else.

There are exceptions. The famous shootout scene from "Heat" does a surprisingly good job at conveying just how deafening gunfire really is close up, for a movie. Although even that is much milder than it would be IRL, due to use of blanks and the aforementioned equipment limitations.

That scene was pretty interesting but can’t help notice that all the automatic guns just fired endlessly. There were a few reloads but it’s astonishing how fast you go through 30 rounds and they were firing way longer uninterrupted. On another note that final shot was amazing cinematography.

I was afraid this was going to be a "fake" primitive technology channel... but it seems that this one, "Primitive Technology", is actually the _only_ real one! It was even used as "a baseline for what SHOULD be achievable in a natural setting" [0]

The video hyperlinked below is a fascinating debunking of most other "primitive" channels.

This guy basically invented the genre and everything’s else has been copping his success. Most can’t do the stuff he does and to differentiate they just make stuff up.
JamesUtah07 commented on Ask HN: What are some cool but obscure data structures you know about?    · Posted by u/Uptrenda
jtolmar · 3 years ago
The union-find data structure / algorithm is useful and a lot of fun.

The goal is a data structure where you can perform operations like "a and b are in the same set", "b and c are in the same set" and then get answers to questions like "are a and c in the same set?" (yes, in this example.)

The implementation starts out pretty obvious - a tree where every element either points at itself or some thing it was merged with. To check if two elements are in the same set, check if they have the same parent. Without analyzing it, it sounds like you'll average findRoot() performance of O(log(n)), worst-case O(n).

There are a couple of simple optimizations you can do to this structure, the type of things that seem like they shouldn't end up affecting asymptotic runtime all that much. The first is that, whenever you find a root, you can re-parent all the nodes you visited on the way to that root, so they'll all be quicker to look up next time. The other is that you keep track of the size of sets, and always make the larger set be the parent of the smaller.

And neither of those actually do anything impressive alone, but if you use both, the algorithm suddenly becomes incredibly fast, with the slowest-growing (non-constant) complexity I've ever heard of: O(the inverse of the Ackermann function(n)). Or, for any reasonable N, O(4 or less).

Is there a name for the data structure/algorithm?

Not to be "that guy", but claiming that 4:15am in California (11:15 UTC) is daylight is really stretching it, at least going by this morning. Also sunrise here is ~5:50 AM. Even for a 7am meeting I typically need lights on in my office until partway through. The room has both eastern and southern exposure in the south-east corner (my desk is literally by the windows).
JamesUtah07 · 3 years ago
Sunrise means that the sun is fully above the horizon. Dusk is when the sun light is starting to appear but the sun is still below the horizon. So yea I think the original 99% is experiencing daylight is from from accurate but almost everyone will be experiencing sunlight… technically.
