andrewljohnson··on Twitter limits users interacting with Trump's tweets about 'stolen' election
Could they have implemented a voting ring detector instead, and not based it on what the content is?

I wonder if toxic content on Twitter could be dealt with more by limiting content that only gets engaged in an extremely polarizing way, with lots of brainless replies, or maybe content that is way more interesting to a person's followers than the rest of Twitter should be voting-ring-censored.

andrewljohnson··on Ask HN: What did you purchase that measurably improved your quality of life?
Didn't accept a bad coffee mug. Kept looking for the perfect coffee mug. Bought a great coffee mug - size, materials, heft, stability, aesthetics.

My preference is stoneware, 12 oz, square-flared bottom, with abstract natural imagery. Pre-warmed before use.

Yeah, seems fitting, "Poaching has been defined as the illegal hunting or capturing of wild animals, usually associated with land use rights." - https://en.wikipedia.org/wiki/Poaching

The "land use rights" part. The analogy works because on some level the company is "your land."

Both a cynical and wrongheaded answer.
andrewljohnson··on Swiss companies must pay share of rent for employees working from home
It’s advantageous for companies to pay for anything that can be construed as a business expense for employees, since that means they can transfer money to the employee tax free. Businesses in the US do this for health insurance, and remote companies can do it for a few more expenses. It makes sense to pay for whatever expenses the company can, as long as the administrative costs don’t outweigh the tax advantage.

Maybe Texas is the problem and not NextDoor :)
andrewljohnson··on How Nextdoor courts police and public officials
Where do you live? This was also my experience moving to Spring, TX (a suburb of Houston), which I'm now leaving because of this type of attitude, among other things.

It's not just NextDoor, many areas are on average racist and insular. One time I was strolling my baby, and there was a group of well-dressed, but wrongly colored, people (men, women, and children!) walking down the street. A woman pulled over in her shiny car to ask me if I knew these people, and I walked on and ignored her question. When I looked back, she had pulled over and was on her cellphone.

Does not compute. If congress passed a stock buyback tax 10 years ago, there would have been less buybacks over the 10 years.
andrewljohnson··on UCF researchers develop new rocket-propulsion system
Thanks, I feel enlightened. You could write press releases :)
andrewljohnson··on UCF researchers develop new rocket-propulsion system
IANA Rocket Scientist, but I'll try.

Rather than have one big continuous burn, the rocket engine rotates to create many small burns, by mixing and igniting small amounts of two gases at just the right frequency and amounts. This apparently leads to a more efficient conversion of chemical to kinetic energy.

This sounds similar to how a car engine uses a fuel injector to inject then burn small amounts of fuel to make the pistons go.

andrewljohnson··on UCF researchers develop new rocket-propulsion system
The question I have after reading this press release is, "Why was it previously thought to be impossible?" as stated in the beginning of the article.

Further down, the release seems to indicate lots of people thought it was possible and have been studying it, "The technology has been studied since the 1960s but had not been successful due to the chemical propellants used or the ways they were mixed."

So just an engineering problem, which are seldom impossible.

andrewljohnson··on A Backpacker's Guide to Maps
Ordnance Survey maps are fairly well done (as good as other sovereign efforts), but the UK's approach to map licensing has probably hurt the country economically and heavily limited distribution of OS maps. OS is maybe the most antiquated map licensing agency I've ever tried to work with.

In the US, you can get the USGS maps for free. In Switzerland or France, you can get SwissTopo or France IGN in a manageable way for reasonable licensing fees. In Australia, it's a little complex, but you can go province by province and license the maps, sometimes for free. Many, many countries provide high quality maps for free or reasonable fees.

But Ordnance Survey's maps are incredibly expensive to license, hard to administer/govern, and can't be purchased for much less (if less at all) than OS charges in their own (terrible) app. And thus aren't in my app like so many others are.

The US approach to making USGS maps public domain has created enormous economic growth. This is a nice paper on the economics of maps: https://pubs.aeaweb.org/doi/pdfplus/10.1257/jep.34.1.196

Twitch is so low: https://www.levels.fyi/comp.html?track=Software%20Engineer&s...

Is that because a lot of people want to work at Twitch, and/or because Amazon doesn't pay that well?

andrewljohnson··on Human Interface: Backpack harness innovation
Yes, I can and have repaired my sleeping bags. My pocket rocket stove is very sturdy and has a sturdy plastic case, and we’ve had it for 14+ years. And I think I’d be fine in the forest without a stove, but honestly if I ran out of food I might not last long... I’m not a survivalist.

FWIW, I’d also keep using a pack I liked. But the takeaway shouldn’t be people should buy old fashioned backpacks... they mostly suck compared to modern packs.

andrewljohnson··on Human Interface: Backpack harness innovation
This seems like a myopic view, like you fell in love with a backpack and built a worldview around it. Modern backpacking gear is extremely light, resilient, and comfortable. You can get packs that ventilate your back. The canvas isn’t really any protection at all from being thrown off a cliff, but a pack filled with soft stuff is. And the external frame is totally unnecessary if your pack weighs 20 total pounds because you have modern gear.

And then mix that in with a jab at disposable culture. You can take good care of a modern pack too, I’ve never had to replace a backpack because it broke.

Sorry to be disagreeable, I just think this comment doesn’t reflect a common reality. I’m no gear head, someone else buys all my gear... but I appreciate modern gear.

Jeez, don’t lie to people.

And don’t listen to blogposts that tell you to lie and call it fibbing.

It’s not ok to be a liar.

andrewljohnson··on Apple delivers a new redesigned Maps for users in the United States
Ah, I apologize... I think you were seeing a bug in our dark mode implementation, which was just released. We fixed it in the next update.

You can share a Membership as long as you don't mind sharing the username/password combo. You'll all end up recording your data to the same account, if you record tracks, photos, etc.

Your family might not need a Membership at all though - that's only if you need to download maps for offline use, or if you want to use different map sources... Gaia Topo and all the features besides mass-downloading are free.

andrewljohnson··on Apple delivers a new redesigned Maps for users in the United States
You should be able to use without an account.

There is a Skip button in the top right corner of the opening screen, or the Register screen. Ping me at andrew@gaiagps.com if you can't find it.

That's fair... we chose to drop the shading at that zoom, but we could be wrong. I think some people prefer a cleaner read when zoomed in so far (especially for field use), and shading also makes the tiles larger/slower to download.

Gaia GPS does have a separate raster hill-shading layer from ESRI you could layer on top, and we've been considering making our own (we already have an elevation data pipeline and create contour lines, so hill-shading isn't a huge step). Maybe that would have a special UX where you could choose to include it or not in your downloads.

I dig your map style!

Thanks, we'll be going strong for another 10 years :)

I think the business is very healthy. Headcount continues to grow, but not in a crazy way, and the great majority of the expenses are R&D. We're certainly default alive.

andrewljohnson··on Apple delivers a new redesigned Maps for users in the United States
Shameless plug, but we just shipped our huge Gaia Topo update too.

Gaia Topo focuses on the backcountry, and specifically downloading for offline use: https://blog.gaiagps.com/easy-to-read-tiny-to-download-the-a...
