jaxn··on Ask HN: What technology is mocked today but will be common within 20 years?
The downvotes you received are the proof you are right.
jaxn··on Removal of Heroku free product plans
Young people use google for YouTube more than anything else. When they search, it’s on YouTube.
jaxn··on Electric vehicles are way more energy-efficient than internal combustion
No way “most” people can use bikes for pretty much everything.

I get what you are advocating for. I have had several periods in my life where I used a bike as my primary form of transportation. But it only works well in a pretty narrow set of circumstances.

jaxn··on Ask HN: Resources to learn generative art programming?
You also can’t cook five star dinners without reading recipes.
jaxn··on Reddit moderators need to be stopped
I have been a mod on one of the top/default subredits, as well as other popular subreddits. There is a lot of crap to sort through in order to keep the overall value of the subreddit.

Did you post the same article to multiple subreddits? Is a fair amount of your post history on reddit links to the same blog? Is your account new? Those would all be looked at when deciding to ban.

jaxn··on Tesla Autopilot Almost Steers Model 3 into Oncoming Train
There are several ways to communicate:

- turn signal to initiate a turn. - scroll up/down on the right steering wheel control to increase/decrease max speed - left/right on the right steering wheel control to increase/decrease follow distance - nudge the gas pedal to be a little more aggressive (starting from a stop sign, executing a turn that FSD has already started signaling, etc - and sometimes I just take control via brake or stalk. I generally don't disengage with the wheel since that keeps the speed on auto.

As for when the loaner didn't stop, it didn't have FSD. So while it looked like my car, it didn't have the same features as my car (just basic autopilot, not FSD).

I have not had situations where FSD was engaged and failed to stop or brake from highway speeds.

On familiar routes with nothing unusual going on, I also can let my guard down. But you do get alerts if not paying attention and will get kicked out of the beta after 5 or 6 of those. I have had 2 of those alerts in the course of the 6-7 months I have been on the beta.

You need to set your forward collision warnings to 'early'. The safety score ding happens at medium. If you have it set to 'late', you will get dinged and never even know it until later.

I think of it in terms of I am still piloting the vehicle, but FSD is executing the maneuvers. This means that I am able to focus on the bigger picture (looking further forward, paying attention to what is going on in all lanes, etc).

I am a MUCH safer driver with autopilot/FSD than without.

So, to your devil's advocate, I am sure I would blame myself if my family member died while driving my car no matter what the car was. But FSD in my car has prevented accidents for me and my family.

Edited to add: I don't want to pretend it is without risks. My biggest fear with FSD/autopilot is that it requires a constant understanding of who is in control. And that is the thing I stress to my friends/family. Your #1 job, and the thing that can kill you, is thinking that autopilot is engaged when it isn't and running a red light or driving off the road on an interstate exit.

Tesla gave me a loaner for a couple days while my car was in the shop. The loaner did not have FSD, and there were a couple of times I expected it to stop and it didn't. It was mentally tough b/c it was familiar like my car, but it wasn't my car.

It used to be close, but not anymore. I am in the beta, so we are talking door-to-door navigation with turns, stops, starts, etc.

Stopping at stop signs / red lights is the biggest game changer. But all of the driving stuff is useful.

jaxn··on Tesla Autopilot Almost Steers Model 3 into Oncoming Train
I used it every day and it does almost all of my daily driving. If it never improves from where it is now, it will be worth the $6k I paid for it.

And yeah, you gotta watch it and pay attention.

jaxn··on Web Push for Safari
Absolutely.

Especially with all the additional fees carriers are tacking on these days under the guise of reducing spam.

jaxn··on Web Push for Safari
Restaurant waitlist notifications. In-store pickup notifications. Travel notifications.

Basically any situation that is some combination of in-person and online. Sure, you can build and maintain an app and then force people to install it to receive notifications. Or you can use/abuse SMS and force people to give their (highly targetable) cellphone number. But both of those alternatives cost more and are less consumer-friendly.

jaxn··on Heroku: Core Impact
Azure/Github seems to be getting close to a buildpacks 2.0 kind of thing with devcontainers.
jaxn··on Don't just shorten your URL, make it suspicious and frightening (2010)
It fits in sms.
jaxn··on Heroku resetting passwords for “a portion” of their users immediately
How about email validation as a first step and send the "this email is in use" message via email instead of on the sign up form.

Adds friction to signup, but would work when it's really important to not leak account existence.

jaxn··on Barcode Detection API
We also scan pdf417 from ID cards. In our case, it was much easier to just use hardware 2d scanners. We are a b2b SaaS and they are scanning IDs all day, so a hardware solution makes sense.

The weird thing about pdf417 is that there is a lot of helpful info our there, up until a point. It's like everyone is collaborative and asking/answering questions up until the point they really figure it out, but those last few steps never much make it into open code.

A couple times a year I go searching to see if anyone has implemented solid pdf417 in WASM yet. It seems like a natural fit to me, and I am sure people have done it, but I have yet to see anything publicly available.

jaxn··on How Does This End?
Hey, no need to be Sour Grapes, Jimmy. It seems likely to me that Putin eventually meets the same fate he has given so many others. Does that solve all of the world's problems? Nope, but it solves one of the world's problems.
jaxn··on How Does This End?
I was hoping for an oligarch uprising that enlists the help of some other former-kgb taxi driver resulting in Putin being suicided.
jaxn··on Ask HN: Tools to visualize data in SQL databases?
I really like the visualization language idea.

I have used Vega + Jupyter a few times. As well as the Vega Viewer extension for VS Code. I haven't used it enough to be proficient and fast, but I have used it enough to know that I want to be.

jaxn··on Slackware 15.0
I also started with Slack floppies, but never really thought about how much it taught me. Disk partitions, files systems, permissions, networking, drivers, etc. It really did force learning at least a base level of all aspects of the system.

I have been a generalist for most of my career and that may not have happened without Slackware.

jaxn··on Ask HN: General Mood of the Community
And fatigue. I think the entire world is just tired.
jaxn··on Thin PostgreSQL Clones
Is this advocating the use of production data in dev/test/qa environments?

I am struggling to come up with scenarios where that would be a good idea.

jaxn··on Slackware Linux 15.0 RC3
Slackware was my first too. I think it was version 3.5 with a bunch of floppies.

Now that so much of my work is in containers, it might be time to go back to slack for the main OS.

jaxn··on Show HN: I built a CNC-machine from scratch, using 40x 3D-printed parts
Really neat project!

Maybe I missed it, but is there a general cost estimate anywhere? I saw the BoM, and assume most the cost is in the router and stepper motors, but is this like ~$500?

jaxn··on Is the world economy entering a wage-price spiral?
If your income is from working a job, then it can only go up via a raise, a different job, or an additional job. But you can only reasonably work 2-3 jobs. The gains are linear and do not compound.

If the income comes from investments,we'll, there are no limits. Each increase compounds.

So yeah, the rich get richer. The system is broken, but it is working as designed.
