rwbt··on Now Available: Ivory for Mastodon by Tapbots
+1. I like Ice Cubes but I can't seem to find a way to load new posts without jumping to the top of the timeline.
rwbt··on Tech execs who raise their kids tech-free or limit their screen time (2020)
Just an observation, I'm a parent of two toddlers and try to limit screen time as much as possible. But if we ever go to my in laws or relatives places they always have a TV blaring in the background. I try not to make a fuss about limiting TV or screen time when we're visiting but they do know my views on screen time.

They are completely fine giving iPads and allowing kids to watch YouTube for hours. I have no idea what it's effects are long term but their kids seem to be doing ok in school so far.

rwbt··on Steve Jobs Insult Response (1997) [video]
I can't believe people compare Jobs with Musk. Jobs was so much better put together in public and seems like he can still be very coherent and persuasive even when angry (likely in this video) and insulted in public.
rwbt··on California pulls the plug on rooftop solar
Most counties require houses to be hooked up to the grid. That's why people who prefer living off grid choose unincorporated lands.
rwbt··on Twitter applies 7-day suspension to half a dozen journalists
Is this his way of going through a public meltdown?
rwbt··on A trip through the Graphics Pipeline
Yep, GL4 with DSA was such a big improvement.
rwbt··on A trip through the Graphics Pipeline
Earlier versions of GL were indeed a lot of fun and easy to get started without much learning curve, but very easy to get into a pickle and blow your foot once the project gets reasonably complex with everything being a state in the context.
rwbt··on As Carvana crashes, used car dealers, not buyers, stand to win big
Easy to blame that it's a manual paperwork driven process, but I'm glad that transferring a legal title isn't a one click process. These are not software EULAs and title related fraud is still a big risk even with all the safeguards.

National chains like CarMax handle this paperwork just fine and Carvana should've invested more in the back office staff rather than overpaying for used Jettas, you know to move fast and break things.

rwbt··on Richard Hipp Speaks Out on SQLite (2019) [pdf]
Yes, Dr. Hipp mentioned it once that there is a foundation in place to take care of things and increase the bus factor. I think that was one of the conditions before Nokia signed their agreement to license SQLite for Symbian.
rwbt··on DHS announces extension of Real ID full enforcement deadline
They're seriously understaffed. Forget about the partisan politics for the reasons behind it but a terrible side effect of this lack of resources is that they only go after the low hanging fruits to audit. Like Joey Banana who forgot to report a few hundred dollars of income will get audited but complicated tax evasion schemes go unaudited.

Count yourself very lucky that you never had an issue with the IRS. I had to deal with a mistake that the IRS made erroneously and even after 4 years it is still not resolved. Every 6 months I get a letter that the IRS still hasn't bothered to look into it and I'm guessing they likely never will.

DMV is the butt of all the jokes, but atleast you can walk into a DMV office and a real person, however annoyed they might be will try to help you.

rwbt··on DHS announces extension of Real ID full enforcement deadline
I'd rather have a federated ID system like what we have currently with state drivers licenses/voter id systems. Social Security Number/TIN is already used as a unique identifier for all financial transactions anyways.

It's messy and complex at times, but in the long run I'd rather deal with a bunch of small state level bureaucracies than a giant federal behemoth that barely functions (looking at you IRS).

rwbt··on The New Smoking (2021)
I'd imagine there's a lot less motivation to build new physical recreation spaces like skateboards etc if almost everyone is starting at a screen every waking minute.
rwbt··on Fast Functional Lists, Hash-Lists, Deques and Variable Length Arrays [pdf] (2002)
Does anyone have experience with this vList data structure in real life applications? How well does it cache? Any production software that implemented this?

It's intriguing but wonder why it never gained traction.

rwbt··on Honda electric moped coming, intended to fit “50cc” category
Love the designs - but how is this better than a modern electric pedal assist or throttle controlled electric ebike?

They made a lot of sense during the oil crisis but why would anyone really bother getting licensed, paying for registration and maintaining insurance when you can get an electric bike and get a very similar experience without all that hassle?

I'm not trying to be dismissive mind you, but genuinely curious if this potential market will be big enough to address it.

rwbt··on Show HN: Structpad: notepad-database hybrid that helps you use abstract thinking
Very nice. Not sure how I'd use it but looks and works great. Also, kudos for using local storage.
rwbt··on Status vs. Wealth: Why the Rich Don't Act Rich
Great book although I don't really agree his concluding chapter of Category X. I don't think one can materially participate in society and also fully extricate themselves from the hierarchies.
rwbt··on No New Streaming Services Will Launch in 2022
Good. This is likely an unpopular opinion but the internet was supposed to bring knowledge, creative expression and so much more to the masses. Instead it devolved into a dopamine delivery machine with non-stop binge consumption and addiction to everyone.
rwbt··on LibSQL is an open source, open contribution fork of SQLite
I wish this project good luck but I'm glad how SQLite team kinda does it's own thing like using Fossil for development instead of Github, not accepting outside contributions, very different code of ethics document etc.
rwbt··on My family’s unlikely homeschooling journey
> Unfortunately, homework is part of the grade and you can't tell the teachers to skip it for your kid.

This is the biggest curiosity killer. Instead of helping them it somehow teaches the kids to become a bunch of obedient rule followers. Maybe that's the intended effect.

rwbt··on My family’s unlikely homeschooling journey
I'm glad to hear first hand experience. Where does one find other parents who are homeschooling their children?
rwbt··on My family’s unlikely homeschooling journey
Homeschooling is interesting. I like the idea, but I'd be more worried about lack of socialization with other children or any kind of group learning. Even more so if the child is slightly introverted.

This is less of an issue if children are raised in the nuclear families like in the olden days, but these days what other avenues are left where children can learn something in a group and form long term friendships other than a school?

rwbt··on We don't know how the universe began, and we will never know
Reminds me of something Karl Popper philosophized about. I'm completely butchering it ofcourse, but it goes along something like this - Every scientific theory is waiting to be falsified by future generations. He concludes that everything in Empirical sciences cannot be proven, but instead they're only falsifiable.
rwbt··on Can the Visa-Mastercard duopoly be broken?
That $25/month fee is for accounts that accept payments. I don't think debit accounts will have such a ridiculous fee.
rwbt··on End of the Machinery Game Engine
Did they get acquired by some big company? Their blogposts always felt like they want to be acqui-hired.
rwbt··on Show HN: C3 – A C alternative that looks like C
> I'm puzzled with what the market for these kinds of languages are.

There's a significant number of C programmers who want something slightly more modern and convenient but don't want to write C++ due to a number of reasons.

I think Zig, D are examples of this niche but syntax wise they don't completely look like C.

rwbt··on Voronoi Diagrams on the GPU (2016)
Yes- the drawing cones performance will eventually bottleneck depending on the num of sites, in that case your proposed solution makes much more sense.
rwbt··on Voronoi Diagrams on the GPU (2016)
Not sure if you read the article till the end but

> On the same machine, the instancing version can do a few thousand seed vertices (an order of magnitude more) at 60 frames-per-second, after which it becomes bandwidth saturated.

If you have a powerful GPU you can get even faster results. I have a project that does Lloyd's relaxation using voronoi and for me the using cones with a depth buffer gave the best result.

rwbt··on Voronoi Diagrams on the GPU (2016)
If you fill quads, you won't get to use the depth buffer to occlude fragments easily. GPUs can do a lot of depth buffer optimizations before they run the fragment shader.
rwbt··on Voronoi Diagrams on the GPU (2016)
Jumping Flooding Algorithm (JFA) gives very good results but you need to do a multi-pass render. If you want a single pass solution and let the GPU handle most of the work you can render cones[1] using an Orthographic view matrix. It is also super fast thanks to depth buffer optimizations.
