> We're calling 400MB RAM usage ultra-lightweight now? OpenBox needs 7MB of RAM, and there are WMs that are even lighter on memory requirements.

My WM uses 1,158K of RAM, or basically just a bit above 1M. This is a very minimal custom thing I wrote years ago that works for me.

But the previous person said "total RAM usage on boot". I was curious enough to reboot: on boot my Linux system uses 310M. That's without Xorg and starting only some very minimal services. After startx it uses about 405M.

"RAM usage" is a tricky topic. I have 32G on my machine and there's no memory pressure at all on boot, so the kernel can just allocate/cache stuff "just in case", but it doesn't necessarily need all that memory to allocate.
What does this mean for the Roomba's long term serviceability? I tend to hear really good things about the product. In Australia the ACCC (Consumer protection office) has decent protections for these situations, but in the USA is it probably that Roomba's will become unrepairable with no consumer recourse?

What's the benefit of the container over installing as a tool with uv? It seems like extra work to get it up and running with a GPU, and if you're using a Mac, the container slows down your models.
> Do regular users even know the difference […]

Honestly, from observing my close family and friends as well as passing by strangers, everyone uses whatever default comes(i.e. Chrome on Android) or again Chrome(on iOS because they saw some banner ad somewhere to install it to access their password stored previously in android life).

The core portal to internet currently appears to be the blue-F(aka Facebook) icon which has an interesting search. People search in Facebook for specific topic and then will reluctantly move over to browser and again search on Google(always default). So, in summary no, everyone uses Chrome and does not know the difference.

Some of my colleagues seem to use Brave and Linux die-hards use Firefox(comes default with ubuntu last I tried ubuntu).

Whatever patents that they had have to be expired, I kind of wish someone would make reproductions. I know there's the 3D printed ones, which are cool in their own right, but since 3D printers aren't super precise the parts have to be huge to compensate. I want as close to a one-to-one reproduction as possible, but I guess there's not much money in it.

> Continuous production implies at least a few people 24x7. Not all chemicals are continuous production

Yes. I'm asking if there is a chemical-production process that can be run 24/7 but which isn't due to labour shortages somewhere that doesn't result in such production being shut down (or protected)?

Chemicals are globally-traded commodities. Some are perishable and/or difficult or even illegal to ship. So there is regional price variance. But ceteris paribus, if it can be run continuously, production will shift to where it is.

> I think that’s probably because the 1990s styling is part of what makes PuTTY what it is – “reassuringly old-fashioned”

This is definitely something that attracts me to PuTTY. There _is_ something reassuring about applications that look the way PuTTY does - maybe the aged look projects stability due to lack of change, maybe it's just the additional cohesion from using OS primitives, I'm not sure. What I am sure of is that I find the opposite to be true for apps with a "modern" aesthetic; the more material design, rounded corners, transitions, low contrast, high padding I see, the more I experience feelings of distrust and skepticism.

I'm not qualified to psychoanalyze it, but I'd hazard that it's not an uncommon interpretation in some user groups, given the pockets of fans of PuTTY-esque design.
Zkt is probably widely implemented even if not declared. Since most RISC-V cores are towards the lower end of the spectrum (in order etc.) you'd have to go to extra effort not to implement it.

AVRs main benefit is the incredible I/O you get from them.

AVR EA has a 16x gain 12-bit ADC on it, for example. And AVR DB has 3x OpAmps on it for free.

There are also LUTs that operate at full clock speed on these AVRs these days. Handy for glue logic (AND / OR / XOR gates, kind of a mini-FPGA on a few pins).
The description was very poor. They could only feed power back into the one circuit that hardware is on, and the would also be a violation of multiple safety standards, as well as the National Electrical Code. That’s a good way to get someone hurt or killed, and to have your ass thrown in jail for sporting such a stupid device.

This is why you have lockout devices on breaker boxes, if you’re going to have an emergency generator that plugs into the same box.

Or you have automatic transfer switches that handle cutting off your feed back to the power company, before turning on any battery or power generation equipment at your site.

Take a step back and look at how it’s constructed, and what the inputs and outputs actually are. It is clear that it’s just a pretty UPS with a weird proprietary wireless communications system, and should be compared against the likes of APC and CyberPower.
I never understood that quote until recently.

If AI can prove major theorems, it will likely by employing similar heuristics as the mathematical community employs when searching for proofs and understanding. Studying AI-generated proofs, with the help of AI to decipher contents will help humans build that 'understanding' if that is desired.

An issue in these discussions is that mathematics is both an art, a sport, and a science. And the development of AI that can build 'useful' libraries of proven theorems means different things for each. The sport of mathematics will be basically over. The art of mathematics will thrive as it becomes easier to explore the mathematical world. For the science of mathematics, it's hard to say, it's been kind of shaky for ~50 years anyway, but it can only help.

I wonder if there could be some sort of NFC/USB Yubikey thingy that resides in your government-issued ID that responds with TRUE if the person is considered an adult. Ideally, it would just leak your nationality (the "is_adult=true" response would be digitally signed by your government at ID-issuing time).

Agree. I mostly do front end in my day job, and despite JavaScript being a bit of a mess lang, dealing with npm is way better than juggling anaconda, miniforge, Poetry, pip, venv, etc depending on the project.

UV is such a smooth UX that it makes you wonder how something like it wasn’t part of Python from the start.
I also have an older home and we had to repair our sewer line. It was clay pipe which had broken in a few spots and had major root intrusion. Thankfully there's some newer technology that makes it significantly cheaper in the right circumstances -- instead of digging up your street connection and laying in new pipe they can blow an epoxy-soaked liner into your existing pipe, then run a curing light through it. It ended up being less than 40% of the cost of replacement and works just as well.
Hey everyone,

I’m Dalton, the creator of CatCompass, and after years of beta testing in my local community, I’m excited to finally launch it globally!

What is CatCompass?

CatCompass is a crowdsourced platform for reporting stray cat sightings. Just snap a photo, and the app automatically tags your location—helping shelters, TNR programs, and rescue organizations better allocate resources where they’re needed most.

CatCompass Impact: Staying Close to the Problem

This platform isn’t just something I built—I actively rescue, vaccinate, sterilize, and find homes for stray cats myself. So far, I’ve personally helped over 20 cats since launching CatCompass. Being hands-on with this work keeps me connected to the reality of the problem—I never want to forget why I built CatCompass in the first place.

By staying directly involved in TNR, fostering, and adoption efforts, I ensure CatCompass isn’t just another app—it’s a tool built from real-world experience, designed to make a tangible impact on stray cat welfare.

CatCompass Sentry: Automated Colony Tracking

CatCompass Sentry is a feature designed to monitor cat colonies 24/7.

Here’s how it works:
• When using the CatCompass camera, hit the shield icon to activate Sentry mode.
• Aim your camera at a feeding station, shelter, or colony location.
• The camera will automatically take a photo whenever it detects a cat—up to 4 times per hour.
• Use an old phone or any webcam-enabled device to continuously track cat activity.

Sentry helps caregivers and rescue groups monitor stray cat activity without constantly being present, making it easier to track colony members, detect new arrivals, and ensure cats are eating safely.

AI-Powered Moderation for Better Data

To ensure accurate and effective reporting, CatCompass features an AI Moderator that analyzes each image for:
• Outdoor settings to confirm the cat is a stray.
• Collars or other identifiers to distinguish lost pets from true strays.
• Eating behavior to track feeding patterns and support Compassion Credits.
• And more

This AI-driven verification improves data accuracy and ensures that every reported sighting contributes valuable insights for rescue groups, shelters, and researchers.

Gamifying Compassion: Earn Rewards for Feeding Strays

Through our Compassion Credits program, users can earn rewards by feeding stray cats. Simply snap a photo of a feeding moment, collect credits, and redeem them for exclusive deals at participating businesses. It’s a way to incentivize kindness and turn everyday acts of compassion into a community-driven movement.

Join Us & Make an Impact

After years of local testing, CatCompass is now live globally, and I’d love for you to be a part of it. Whether you’re a cat lover, a TNR volunteer, or someone who just wants to make a difference, your contributions can help shape a better future for stray cats.

In Signalwire’s defence, reading through the old mailing list, I got the feeling they drove the development of Freeswitch for years without being properly compensated by downstream projects. Sadly I’ve also seen other parts of the Voip community recalibrate their generosity when it comes to open source and I honestly can’t blame them.

I don't disagree, people can learn new keystrokes and workflows, but it just makes it a tougher sell.

Imagine that you've been using Windows for twenty years. You have been doing paid professional work with Adobe Premiere for twenty years. You have a workflow with the two that has worked for about twenty years. Linux might be better, but it's probably not that much better than the setup you have right now, and the applications you have built your business on don't exist on that platform, and there would be a pretty steep learning curve to pick up the new stuff.

I can't speak for anyone else, but I probably wouldn't move to Linux at that point.

Now, if I were already using the Windows version of Lightworks or Resolve, that might be different; a lot of my knowledge would transfer over, and that might be enough for me to change over.
I know your intention is probably well placed but we do though need to factor in revenues:

Year Revenue
---- -------
2007 $75M
2023 $653M

I bring this up because G&A of big companies (in general) always outpaces R&D once they hit scale ... and in an ideal situation - your revenues should outpace R&D expense because you're getting economies of scale (which further dilutes the R&D to Other Business Function comparison).

And Mozilla has hit scale / become "big company" - with those kinds of revenues.

The reason why G&A outpaces R&D, is because now you have all kinds of work to do that you don't have to do when your small/underdog, like:

- regulatory compliance

- legal

- privacy

- advocacy

- public relations

- etc...

When you're the underdog, you don't have to deal with these activities and as a result, your expense base is more heavily skewed toward R&D.
I’m enjoying UV a lot as well. If anyone from the Astral team sees this, I’d love to request more functionality or examples around packaging native libraries.

At this point, just thinking about updating CIBuildWheel images triggers PTSD—the GitHub CI pipelines become unbearably slow, even for raw CPython bindings that don’t require LibC or PyBind11. It’s especially frustrating because Python is arguably the ultimate glue language for native libraries. If Astral’s tooling could streamline this part of the workflow, I think we’d see a significant boost in the pace of both development & adoption for native and hardware-accelerated tools.
government agencies aren't the ones building the knowledge, know how and world wide soft power of a country. it's the people and their businesses. a government is meant to govern the administrative tasks of everything imposed by the social contract of a country, nothing more. and given that the US is built on a foundation of liberty.

how much more are american taxpayers expected to foot the bill for? a lot of them work two or three jobs and still cant make ends meet.

I do not want my data included in the dataset. "We're not looking at it, pinky swear!" rings hollow.
yeah it's a cool concept, but knowing what I know about the ability of generative AI to accurately replicate specific moments of history, it falls flat.

The whole point of this kind of thing should be to reward people who can recognize "that architectural style wasn't invented until the 13th century" but that's precisely the sort of thing image models cannot do reliably.
This was one of the reasons I bought into the recent Raspberry Pi 5 tablet the Pilet on Kickstarter --- I'm hoping it, or a Raspberry Pi connected to a Wacom One or Wacom Movink 13 will work as a general-purpose device.

Actually, he sounds like the opposite, but anyway.
Mise does way more than uv, it's a much larger scope than just Python tooling.

I think the current status quo, that of mise utilizing uv for it's Python integration support, makes sense and I don't see that changing.

Also, FWIW, mise has other methods for Python integration support, e.g. pyenv, virtualenv, etc.

Edit:

Ha... Didn't realize who I was replying to. Don't need me to tell you anything about mise. I apparently misinterpreted your comment.

Show HN: Sync your Govee lights with live sports
Hello all! I posted this on a few sports pages, and I've had alot of people interested, so I wanted to share it here too.

Lumealert connect's your Govee (Philips Hue coming soon!) smart lights, and syncs with live sports events.
We currently support NHL, MLB, MLS, and EPL (Premiere league).

We're in a good place to let some people give it a try, tell me what works, what doesn't etc.
Currently, there are 3 scenes.

Scene one is "game day morning", which will automatically turn your lights to the color of your team. This happens around 3am est, on game day.

Scene two, is the classic scoring. Anytime your team scores, you can run a custom diy scene (that you created within the govee app) to play. This lasts 10 seconds then reverts back to your color.

Scene three, alert when your matchup starts. Whenever your match starts, you can set custom color/custom DIY scene to play on your lights for 30 seconds.

We have so many more "scenes" in the works and plan to release 1-2 a week

Right now, there currently is a One device trial - no credit card needed.

These lights will only work with wifi controlled devices.

If this sounds up your alley, please register at

www.lumealert.com

Note: after registering, you'll be brought to the dashboard where you can add your API key. There are instructions on that page how to do it.

Please don't hesitate to reach out on here if you have any questions, feedback, etc.

my workflow involves switching between files in working set, sometimes going back to staged. The git panel is easier to navigate than the file tree. I also need to see all the markers for recent changes I made, they are in git diff

For the actual commit often I have to do terminal because VSCode would fail to give me the relevant commit hook error message.
