Earlier quoted context omitted.

If two cars travelling the same direction contact each other such that the front axle of one car bumps the rear axle of the other (the car in front), it's usually the car in front that has the safety problem. This is the same principle behind the PIT maneuver.

If there's a rear end collision severe enough that the axles are contacting each other, both parties have a safety problem.

I wasn't talking about that. I meant lateral motion

Working on Circuitscript, a language based on python to describe electronic schematics/circuits: https://circuitscript.net/

The main motivation for creating Circuitscript is to describe schematics in terms of code rather than graphical UIs. This makes it easier to track changes and version control with a text based schematic. I have used different CAD packages extensively (Allegro, Altium, KiCAD) in the past and wanted to spend more time thinking about the schematic design itself rather than fiddling around with GUIs.

The main language goals are to be easy to write and reason, generated graphical schematics should be displayed according to how the designer wishes so and to encourage code reuse.

I started a new project: https://lifeweeks.app/ It's a way to create a visualization of your life in weeks, based on Gina Trapani's version that I saw here last week. Would love feedback if anyone has any!

Super cool. I have something similar in my browser tab for years now when I open a new one

Nice. Is that an extension?

I've been updating my HN bot (watch comments for keywords and post to Slack/Discord) written in Crystal to use raw SQL instead of unmaintained ORM. Turns out the whole app needs only ~ 10 SQL requests, and it's way funier to write modern SQL than fighting the ORM. The new code looks like this : db_message = Model.save_new_message!(@conf.db, DbButler::Hn, item, DbState::Processing) Than I have a Model module with all…

Hmm any plans on integrating it with Discord instead of Slack? Also, aware of https://f5bot.com/?

I'm creating an infinite canvas that has all your organization's code and documentation on it. If you zoom in, you can see the code, if you zoom out you see the big picture. By giving everything a place on the map, it becomes easier to figure out your way through the landscape and understand the systems. Different modes can you show you different things: code age, authorship (bus-factor, is the person still with the…

Sounds awesome - out documentation is suffering a bit so something like this would be incredible.

I've looked into replacing windows but decided that that's going to be one of the things that I'll let professionals do. The ironic thing is that not only are the tradies expensive, but prices for renting specialty machines are also crazy high where I currenly live. Like, I looked into renting a stand-up concrete grinder/sander -- $100 for 4 hours! Plus, you need to buy the sanding attachments which are another $200…

The window part ist not that hard as long the windows don’t weight too much. Of course, the wall opening should be somehow suitable and the wall stable enough to accommodate new thick and long screws (sadly not my case). I am buying all the tools. AliExpress price and quality level if I don’t need them much. Good quality ones for the bigger tasks. I tried renting at the beginning, but it’s very expensive at the end.…

Yes, I have also bought a lot of tools which I never needed before in my life. And like you, I'm also usually going for the lower end price-wise because chances are that I will not ever need them again after our reno. And frankly, most of the time the tools are completely fine for me.

Interestingly, there already were a number of times where a tool came in handy that I had bought as some point in the past not when I had a need for it at that point but because it was on sale. And if not, I could always resell it, although I probably won't because it's not worth it.

As for the concrete grinder, I actually looked into buying one coming from the same mind set. But the kind of machine that I could rent for 100 bucks costs North of $3000 if I bought it new. And I will likely never need it again after using it once. So this time, I'm surely not going to buy one.

With the windows, I know there's quite a difference in terms of installation depending on where you live. For instance, in the US, you basically buy a window with a flange on it, put it in the whole and screw it into the studs. Then you foam spray the gaps and trim the window. In Germany, installing a window (to code, mind you) is a whole production. Even just measuring what kind of window to order is non-trivial. And I'm sure there's lots of variations in other countries as well.

I've been building https://mentions.us for the last couple of months. It's a little web app that monitors Reddit, Bluesky, Mastodon, Hacker News and a bunch of other sites for keyword mentions. Not an original idea (F5Bot has existed for at least 8 years) but a fun project, and I think it can make a contribution by monitoring more sources and having a free tier that includes sending Slack messages.

It has taken a couple of months to go from idea to a product that's polished enough for other people to use, and I've been full time on it. It has a couple of dozen companies using it now, almost all from the last couple of weeks. That's been a big boost!

I think an AI powered f5bot is needed. Curious to know that are you integrating API of these platform or some other way?

Yeah, it's on my list. When you're scanning sites with high volume (Reddit has ~300 posts per second, Bluesky has ~100) you have to keep things fast and cheap, so I think keywords still have a role, but I think they can become an implementation detail.

My plan over the next couple of months is to build the option for users to enter the kind of things they want to scan for, have AI convert that to keywords, use the keywords for the (fast) scanning, and then apply additional filtering using AI to the small number of posts that match.

Not built yet, but I think there's a bunch of promise to using AI to find relevant conversations online.

Re: APIs, yep, all APIs. I'm not doing any web scraping at the moment
