nicpottier··on Comma.ai, self-driving cars and indefinite optimism
Man, you have a lot of hate for CR. I think their report makes it very clear that these aren't recommendations of systems in any way but rather an attempt to start formalizing testing and the state of various systems that are out there. In multiple places they say this is a report FOR THE INDUSTRY, not consumers.

They even have a specific callout for Comma:

> A determination was made to include the Comma Two Open Pilot system manufactured by > Comma.ai. Although Consumer Reports does not endorse after-market modifications to all > consumers, we feel that it is important to include the test results in this report to the industry. The > direct comparison of this system to the other OEM systems will hopefully provide insight on this > alternative approach and highlight the areas across the industry that have room for improvement.

It is at least SOMETHING. I haven't seen anything else even close to as formalized that looks across all the various systems out there. Do you have better ones to look at?

nicpottier··on What’s interesting about the Florida water system hack is that we heard about it
I think scale is the answer to that. These systems are being scanned for day and night for vulnerabilities from attackers and once they have infiltrated can lie in wait to do something whenever they want. A foreign actor can do that at massive scale undetected (both when successful and when not).

Same isn't true for physical security.

nicpottier··on What’s interesting about the Florida water system hack is that we heard about it
My wife is a sewer commissioner for a tiny sewer district up in the mountains. It is a state of the art facility from a water treatment perspective since the treated water exits into a mountain stream. However, they recently needed to update their control systems because they all currently run on Windows98 and can no longer get spare parts from their vendors etc..

At her request I sat in on a meeting with their vendor to ask some stupid questions (but less stupid than what the commissioners would have asked) about their proposal for updating the control systems.

Some crazy things discovered:

* it's all windows, all the time. I don't know why but I find this disturbing, but apparently all the drivers for these systems only work on windows. I guess Linux is only just starting to penetrate this market.

* yes, remote access is a thing (even in the old system), especially in this case where the plant it under 20 feet of snow half the year. They claim the system can only monitor things, not control things, but I wonder how locked down that really is. Security is via a VPN.

* the vendor at play here seems to be a tiny shop of a few people that basically serve a few dozen sewer treatment plants in the area. They deal with replacing the hardware and programming these interfaces in.. kind of a crazy local cottage industry I just wasn't really aware of.

Having a background in web services / unix left me pretty unprepared to really do much more than ask some stupid questions around security / obsolescence, but the vendor had reasonable answers to my concerns. Just a very different world than what we think about every day.

nicpottier··on What I Learned in Avalanche School (2019)
This isn't true at all. Risk is not at all constant over time. There are stats in the climbing world that are similar and it is a jagged line with risk tolerance going up, then diving down after each close call etc.. but trending upwards.

"There are old climbers and there are bold climbers but there are no old bold climbers."

nicpottier··on How to lower the price of plant-based meat
100 percent agree. I'm almost entirely vegetarian but would occasionally allow myself a burger as a treat as it is one of my favorite meals when I have a real hankering. A Beyond or Impossible patty now completely satisfied that craving. They really have done a great job of it. Note I am not saying they are indistinguishable from real beef, but they are meaty enough in a way that scratches the itch which previous products never did.
nicpottier··on AirPods Max: An Audiophile Review
I still have a pair of Sennheiser HD 280 Pro's I bought 20 years ago. That seemed like a lot of money for headphones back then. They have followed me to multiple continents, been on lots of flights and have had their pads replaced and still work great.

I recently moved to Bose NC700s because ya, wireless sure is nice, but I'd be surprised if they last 10 years, much less 20. Still have the HD's though and use them now and then.

nicpottier··on SARS-CoV-2 501Y.V2 escapes neutralization by South African COVID-19 donor plasma
This is an interesting take for sure that I hadn't heard before. Do you have more information on how they could have accelerated things?

If feels like the risk of shipping a vaccine that later is found to have adverse side effects would be so dangerous to the trust of the FDA that it would be really dangerous. Think of the shattered trust on both the FDA side and on vaccines in general, feels like maybe that would be too big a risk to take.

nicpottier··on Ask HN: I'm quitting my job, will create a game – any advice?
A million yes to all this!
nicpottier··on Ask HN: I'm quitting my job, will create a game – any advice?
Right. Ya, in truth I think the big studios were all built off a single hit. And those hits keep paying out for a long time and they leverage either the brand to build sequels or just start stringing out new titles hoping another will "hit". Cross-marketing is huge too.

You can be successful building mobile games, just like you can win the lottery. :)

nicpottier··on Ask HN: I'm quitting my job, will create a game – any advice?
I should add that we decided to stop doing this when we realized we were now playing the lottery for a living. We had a few times where we got featured in stores and made thousands a day but didn't take off from there and that was that for that title.

If I can offer any advice it is to focus on simple mechanics and keep production costs way down. Don't spend more than three months on launching your first title.

nicpottier··on Ask HN: I'm quitting my job, will create a game – any advice?
I built games full time for about five years, straddling the transition into smartphones.

Building a mobile game that is profitable is a bit like the lottery. You need to build something great to have a chance of winning, but building something great is not a guarantee that you will win. I realize that goes for most business ventures, but I think it is more true for mobile games than most.

What captures the imagination of an audience is in large part a guessing game and a matter of luck. You can look at past successes as a demonstration of that. Flappy Bird was a hit for a bit but it wasn't exactly clear what was so different about it than so many before. Angry Birds started an insane franchise, but I'm not sure if the same game were launched today whether it would capture the same share of the market. It is just really really ephemeral.

But making games is fun, like really fun! I had more fun in those years than I have at any other point in my career. We were banging out a game a month and having a blast doing it. This was very early so we knew there was audience enough for each of those to pay the bills, but I wouldn't count on that these days.

So all of that to say, do it! But don't expect to pay the bills doing it. Maybe you will, maybe you won't, but it is very much either rags or riches with very little predictability on where you arrive.

nicpottier··on YouTube will now show ads on all videos even if creators don’t want them
Do you have any source on how they distribute payments? All I can find is this blurb which could be read lots of different ways (likely by design):

"Currently, new revenue from YouTube Premium membership fees is distributed to video creators based on how much members watch your content. As with our advertising business, most of the revenue will go to creators."

I support some creators via Patreon as well, but honestly that's just more work for me as my interests change and some months I don't consume any of their content.

I imagine the truth is that it is likely something Spotify-like or some variation thereof. I'm still ok with that and YouTube does make it explicit that the majority of my sub goes towards creators. FWIW I suspect there are some reasons that are subtle, bug valid, that Spotify for example distributes subscription fees the way it does, which I agree does seem kinda BS at first blush.

edit: some anecdotal info here saying that creators are indeed paid (handsomly) based on views: https://www.reddit.com/r/youtube/comments/9agg5f/how_does_yo...

nicpottier··on YouTube will now show ads on all videos even if creators don’t want them
> Its like paying a restaurant not to harass you and then going to it when you could just go to the restaurant next door without the protection fee.

No, it's like paying the restaurant for the damn food. YouTube hosting all the world's videos forever is not a god given right, nor is being able to watch content people create for free.

I despise ads, absolutely despise them, but gladly pay YouTube the $15/mo to remove them because I know good content needs to be paid for one way or another. There's still a few channels that I like that put in ads during the videos and that's still annoying, but otherwise I never see an ad.

And this is fucking fantastic! Imagine if the web as a whole adopted this. (I know there are efforts including Google's) If I could pay $10/mo to get rid of all ads (explicit and implicit) and have that go towards the creators that I consume content for, then we'd be in a much better place. (imagine if FB just got a cut of that for example, how that would change the dynamics)

nicpottier··on Goodbye IFTTT
Seems like they are making the right choice if they are driving away a "customer" that had many services connected but was paying them nothing. That's no way to run a business.
nicpottier··on HP-28S Battery Compartment Door
These aren't very good examples of what is currently possible using a decent FDM printer. (Prusa Mk3s for example) While not beautiful, PLA prints are pretty darn smooth and surprisingly strong if you orient the print in the right direction. (you don't want to stress the part on the axis of the layer stacking)

I bought one a year or so ago and while definitely still in the "toy" category, you can do some neat things with them. That said, woodworking is going to let you build way nicer things, but you don't get to just click a button and have it reproduced, nor share plans with others. But ya, FDM doesn't print things that are "nice" really, just functional.

nicpottier··on Caddy Server Is Acquired By Apilayer
This. That CLA does not assign copyright, so they can't relicense. I'm sure they know that though and either scrubbed those out at some point or are pursuing other ways of monetizing it.
nicpottier··on CodiMD, self-hosted, real-time collaborative markdown notes
Ya, I feel like the commenting system in Google docs is the main killer feature for collaboration. I would love to use Markdown for everything (can we just make it a standard email format already?) but the commenting system in Google docs is keeping us there for the time being.
nicpottier··on Inefficient, but Smart
I recently moved back from living in Ecuador for four years and I can say the inequality there is far far less than it is in the US. Your point is totally valid in many places, but Ecuador is a weak place to make it.

Carpenters seem to make a fair wage there, it is the norm to buy things that were manufactured by the shop you are buying from and that can range from inexpensive to bespoke and higher end.

As someone else mentioned Ecuador works really well as an economy for the things it gets to keep within its borders, which is a lot since they have a surplus of oil, great agricultural resources etc..

But once you start importing things the gap widens a ton. Cars are very very expensive (the few manufactured locally a bit less so) due to import tariffs. iPhones just aren't really a thing. And getting a big LCD monitor there wasn't even an option at any price, I lugged one in in a suitcase.

The craziest bit is that Ecuador is dollarized, so they don't even get to print their own money!

I generally have believed that as well, but wonder if there will be some flight away from cities after all the dust has settled, at least in the shortish term.
nicpottier··on Epidemic Calculator
Also though this may be falling into speculation but trying to account for total # of beds and peak hospitalization and adjusting outcomes when in that zone may add another important element when trying to reason about this.
nicpottier··on Epidemic Calculator
Super well done. Have you shared this with epidemiologists who have validated it? Hard to avoid some bugs no matter how careful you are!

What are the default values representing out of curiosity?

Seems the biggest bit here is the pause to intervention and how big your R0 is after intervention. Anything over 1 for the US population and it seems to get ugly fast.

nicpottier··on Google's Abandoned Android Authenticator App
Does anybody do this? I've read that as well but it doesn't make sense to me. How do I add my backup device if it is in a vault somewhere? For that to be useful I would have to have my backup device on me so I can add new accounts, but then that defeats the purpose.

I could see this working for a few very secure logins, but if the idea is to two factor everything it doesn't seem tenable.

nicpottier··on Tailwind UI
I had a similar recoil to this approach and then I tried it, and I think they are actually onto something.

Yes, you may have more than one card in your system, but in all likelihood you aren't repeating the HTML for that card more than once, rather you have it in a template of some kind which is called. So while you may have more than one card on your site, you probably don't have the template for it defined more than once. (at least ideally you don't)

For those cases where you do want to extract that code, Tailwind makes that easy to do.

Tailwind is a weird thing and like I said I really thought it was insane at first. But after rewriting a site in it in a few days I have to say it is better than the standard semantic CSS by a mile.

nicpottier··on Tesla teardown finds electronics 6 years ahead of Toyota and VW
Standard range is $40k, AWD long range is $50k. Paint is $1000 extra for anything but black, $2000 for red. Where are you getting $64k?

nicpottier··on Apple engineer killed in Tesla crash had previously complained about autopilot
Obviously take with a grain of salt give the source but.. https://www.tesla.com/VehicleSafetyReport

"In the 4th quarter, we registered one accident for every 3.07 million miles driven in which drivers had Autopilot engaged. For those driving without Autopilot but with our active safety features, we registered one accident for every 2.10 million miles driven. For those driving without Autopilot and without our active safety features, we registered one accident for every 1.64 million miles driven. By comparison, NHTSA’s most recent data shows that in the United States there is an automobile crash every 479,000 miles."

Yes, people disengage auto-pilot (or it does so itself), but it is at least plausible to say that in this like-for-like comparison of drivers and vehicles self-driving is at least comparable in safety.

nicpottier··on Apple engineer killed in Tesla crash had previously complained about autopilot
I'm not sure what you are saying actually maps to reality.

Frame and chassis have never been safer and manufacturers continue to improve. Many (most) new cars have automatic emergency braking that continue to improve. New cars seem to have an ever increasing number of air bags to protect passengers.

All these things are happening at the same time that self-driving is taking place. Tesla FWIW is pretty good at all the above despite their focus on self driving as well.

I agree it is just as ridiculous to say we need level 5 to be make something useful. Will it be decades before we have cars without steering wheels? Sure, maybe even longer. But what exists is already pretty great in most environments and only getting better. (IE, crawling along in a traffic jam at ~15mph is something I would really love to never do again and it seems self driving systems can handle this with aplomb these days)
