New comment by larelli in "Every new car sold in the European Union must include a driver monitoring camera"

larelli — Wed, 08 Jul 2026 06:50:41 +0000

The only time our 2025 Kia warned me about being distracted was about 30 minutes into a highway drive in Europe during heavy snowfall. The roads were covered in snow, people were generally cautious but traffic was still flowing and I was checking mirrors more frequently than usually to make sure lanes around me were clear and I was aware of everything going on. I guess staring straight ahead without situational awareness is the way the car prefers. :|

This sounds really neat. Is it a commercial product or did you build them yourself?

New comment by larelli in "Tapping Morse code on a wall"

larelli — Sun, 25 Jun 2023 18:21:35 +0000

The only Morse code message I know is SOS which is ...---... and I imagine it's reasonably easy to understand when being tapped in an emergency situation. It would tell rescuers that someone is still alive and to continue their search.

The article goes to great lengths to describe the difficulties in manufacturing and assembling the mechanism in the band itself but then also mentions that there a large ecosystem of third-party bands available. How do all those get made? Does every manufacturer have to use the same high-precision machines?

New comment by larelli in "Europe Is Guaranteeing Citizens the Right to Repair"

I'm in the same boat. What kept me from replacing the battery is that the device is EOL and won't receive any software updates, including security fixes. Did you also change the firmware?

New comment by larelli in "How to properly manage SSH keys for server access"

larelli — Sat, 26 Sep 2020 18:15:58 +0000

I think I understand how signing keys removes the need to update every server when adding a user to the system, but it seems like that comes at the price of having to update them all when someone leaves to revoke their certificates. What is the benefit of pulling revoked certificates to all servers periodically vs pulling authorized_keys files? Is it possible to work around this at all, e.g. conceive a system that eliminates all needs to push to servers? Is an online lookup like LDAP the way to go there?

The Reaction Control System (RCS) [1] uses hypergolic fuels [2] which are highly toxic. Such fuels are desirable in this application because they combust whenever the fuel and oxidizer are brought in contact. There's no need to an ignition system, which reduces the chance for failure.

Ask HN: Failed one-person online businesses (and lessons learned)?

larelli — Thu, 24 Oct 2019 16:02:56 +0000

A recent thread discussed successful one-person online businesses (https://news.ycombinator.com/item?id=21332072)

I'm curious about the failed attempts, lessons learned, and what advice others would offer.

* How many people here have tried starting a one-person online business but feel that they have failed?

* What would you do better next time? What lessons did you learn?

New comment by larelli in "That New Memory Smell: Tech Can Tell If Your Flash Is New or Recycled"

larelli — Mon, 07 May 2018 17:23:34 +0000

From the headline I assumed that technicians were literally able to smell whether a chip is new, possibly by it releasing gases shortly after production. It reminded me of the distinct smell of new hard drives when you open the factory sealed pouch.

I was slightly disappointed when I found that the article describes software based testing instead.

I tried "curl ipdata.co" and got a 301 page. It'd be great to get the same json back that's shown on the webpage.

New comment by larelli in "Some Internet Archive employees to receive some of their pay in Bitcoin in April"

larelli — Fri, 22 Feb 2013 12:34:01 +0000

I found the title of this post to be misleading or at least stressing its point. The article says

"Some Internet Archive employees have elected to receive some of their pay in Bitcoin in April."

so it's not all employees, not all of their pay and not all of the time, as I expected from the headline.

I could memorize it from the moment I realized that it works exactly like 'cp', i.e.

cp

Hence I think of it as

ln

Couldn't someone at Google provide a dump of the wiki. Assuming that they have it in their page cache they might be willing to help, given they seem to be one of the largest organizations using Python.

Are you the benjy from the site? Thanks for the help.

larelli — Mon, 14 Jan 2013 13:24:40 +0000

I really like the idea, but I'd do even more so if I could install a cronjob to automatically download a file with all aliases I previously added to my online profile. Of course this comes with security implications you'd have to sort out. Please do this (or let me help you with it).

Edit: I just found the feature on the site and am happy now. (:
