>They have developed a huge arsenal of coping strategies to avoid improving FreeCAD and the results speak for themselves.

Exactly. These FreeCAD "strategies" you mention align themselves perfectly with the objectives of the legacy CAD industry: To delay; break; and obfuscate opensource CAD.

In other words: The FreeCAD team may not be infiltrated by the legacy-CAD industry, but its behavior is entirely consistent with such a state.

One solution is to fork the behemoth; but if FreeCAD is a hedge-maze-by-design, the only way to win is not to play the game: Build alternatives elsewhere, from scratch.

FreeCAD feels like a time-drainer honeypot. Though whether by accident, or malice, is unknown.

> Don't let your dog run errand and use a good leash.

I think the key part is who are you talking to. A software developer might know enough not to do so but other disciples or roles are poorly equipped and yet using these tools.

Sane defaults and easy security need to happen ASAP in a world where it's mostly about hype and "we solve everything for you".

Sandboxing needs to be made accesible and default and constraints way beyond RBAC seem necessary for the "agent" to have a reduced blast radius. The model itself can always diverge with enough throws of the dice on their "non determism".

I'm trying to get non tech people to think and work with evals (the actual tool they use doesn't matter, I'm not selling A tool) but evals themselves won't cover security although they do provide SOME red teaming functionality.

Nice.

I just use org-mode + lots of recurring tasks.

Like car.org has monthly tasks for check fluids, clean inside, clean outside. In April and October theres a task to remind me to change tires and as I'm German a task to remind me yearly to check the first aid kit (you get a fine if its expired and they spot it when they stop you).

So, almost every appliance has its org-file with routines. Same for me and my family, check vaccinations, see the dentist ...

So, if you are already using org, theres no need for an additional tool. Plus, its all text, just throw it in your git. Also, there's tools like beorg to have your org on your iPhone.

> I's still a long way towards fascism for USA to actually lose its attractiveness

Hard disagree. They are on a road to totalitarianism. Unless there's a quite violent change of course, it's just going to get much worse.

Have you not seen the president and his people go after: Political opponents, Attorneys, Leaders and workers in the government who dare to disagree, Immigrants and tourists with the wrong opinions, Journalists (because they power and can expose some of the lies and corruption).

Have you not seen the Trump family and friends becoming very rich, and giving out contracts to their friends?

Have you not seen the government being weaponist against the maga "enemies" ?

This is what fascism looks like.

I agree and it has been my almost exclusive go to ever since Gemini 3 Pro came out in November.

In my opinion Google isn't as far behind in coding as comments here would suggest. With Fast, it might already have edited 5 files before Claude Sonnet finished processing your prompt.

There is a lot of potential here, and with Antigravity as well as Gemini CLI - I did not test that one - they are working on capitalizing on it.

Solvespace is nice, but missing fillets and chamfers is kind of a deal-breaker. Last time I tried it it also had issues with small holes turning into diamonds.

That said, pre-1.0 FreeCAD had a terrible UX so it was the best FOSS CAD option.

With the 1.0 release of FreeCAD the UX is much better though. There are still a few WTFs (e.g. it took me quite a while to figure out rollback is done via right-click->set tip, or something like that)... But overall it's better than Solvespace now.

> Osaka recorded more than 90 cases of water pipe leaks under its roads in the 2024 fiscal year, according to the city's waterworks bureau.

I must admit, that seems pretty small given how many roads and many people said infrastructure supports.

Still a good idea to get ahead of maintenance, but I am pretty impressed.

I wonder if Japan is suffering the same issue many western countries are facing, where regulation and wages are becoming too high to get much done with that amount of money. In my country, I would be surprised if you could replace a single roads water pipes for 3.6million.

ya i do definitely agree that learning Vim is gonna help my overall understanding for how things work at a deeper level and also fight back a lot of the “learned helplessness” that i did develop when coding w/ AI to your point
also another thing that i was thinking is that yes short term (maybe the first few months?) i wouldn’t see any benefit… but it would definitely help in the long term and that my coding ability is not just directly tied to whatever the latest model is capable of
Show HN: AstroLens – AI that watches the sky and finds what nobody catalogued

# Show HN: AstroLens -- AI that watches the sky and finds what nobody catalogued

*https://github.com/samantaba/astroLens** (MIT licensed, Python)

AstroLens is an open-source tool that downloads images from sky surveys (SDSS, ZTF, DECaLS, Pan-STARRS, Hubble, and others), runs them through a Vision Transformer + out-of-distribution ensemble + YOLOv8 pipeline, computes galaxy morphology, and cross-references everything against SIMBAD/NED/VizieR. It's designed to run autonomously for days.

*Results from a 3-day validation run* (zero human intervention):

published results in https://www.linkedin.com/pulse/astrolens-v110-teaching-ai-wa...

- 20,997 images from 7 sources analyzed
- 3,458 anomaly candidates across 354 sky regions
- Independently recovered SN 2014J (Type Ia supernova in M82), NGC 3690 (galaxy merger), and SDSS J0252+0039 (gravitational lens)
- YOLO transient detection went from 51.5% to 99.5% mAP50 by training on data collected during the run itself
- 140 self-correction cycles, zero errors

*What makes it interesting*: The pipeline is self-correcting — it adjusts OOD thresholds, rebalances survey sources based on anomaly yield, recalibrates its reference distributions, and handles errors autonomously. It's not a batch job; it's a continuous system that gets better as it runs.

*Honest limitations*: It found known objects, not new discoveries — this validates the pipeline but the real test is pointing it at less-explored regions. OOD detection on astronomical images is inherently noisy (the boundary between "unusual galaxy" and "imaging artifact" is fuzzy). The self-correcting system helps, but false positives remain a challenge.

Runs on a laptop (CPU/MPS/CUDA). Desktop app, web UI, CLI, Docker.

Built with Python 3.10+, FastAPI, PyTorch, Ultralytics, PyQt5.

The article provides absolutely no data to support any claims of a brain drain away from America, towards Europe or anywhere else.

There are no actual numbers for emigree PhDs. Government losses across all agencies are some 10900 scientists [0] or ~14%. Whether they retire, emigrate or no longer do science doesn't matter for the outcome.

### Maximizing Productivity in Chrome Without a Mouse

- If you care about productivity, reducing mouse usage in Chrome makes a real difference.
- Most frequently used features can be handled with a single keyboard shortcut.
- Internalizing these shortcuts noticeably speeds up tab management, navigation, and development workflows.

### Essential Tab Management Shortcuts
- Switch tabs: `Ctrl/Cmd + Tab`, `Ctrl/Cmd + 1–8`, `Ctrl/Cmd + 9`
- Close / Reopen: `Ctrl/Cmd + W`, `Ctrl/Cmd + Shift + W`
- New window / Incognito window: `Ctrl/Cmd + N`, `Ctrl/Cmd + Shift + N`
- Search all tabs: `Ctrl/Cmd + Shift + A` → Especially useful when you have many tabs open
- Open history: `Ctrl/Cmd + Y` → Perfect for “What was that page I just visited?” moments

### Basic but Essential
- Back / Forward: `Ctrl/Cmd + [`, `Alt + ←`
- Scroll: `Space` / `Shift + Space`
- Focus address bar: `Ctrl/Cmd + L`

### Hidden Power of the Address Bar
- Use it as a calculator (type expressions directly)
- Perform instant unit conversions (e.g., cm → inch)
- Type `@` to switch search modes (including AI mode)
It’s not just a URL field — it’s closer to a quick command launcher.

### Developer Shortcuts
- Open DevTools: `Ctrl/Cmd + Option/Alt + I`
- Toggle element picker: `Ctrl/Cmd + Shift + C`
- Hard refresh (ignore cache): `Ctrl/Cmd + Shift + R`

There are a few keyboards out there that move the numeric keypad to the left side of the keyboard, so that right-handed people don't have to move their right hand quite so far to use the mouse. Basically, like a tenkeyless (TKL) keyboard, but keeping the keypad.

I'd love to try one of these for a while.

The slab of glass has about the size of a CD and despite having less capacity per slab the storage volume for a given amount of data would be about half of what would be needed now with the biggest HDDs and similar to the volume required by tape cartridges.

So the density is already good enough.

The main problem is the cost of the lasers used for writing, which would have to be reduced for mass production. The second important problem is the writing speed, but there also the cost of the lasers is the main problem, as for a greater speed more lasers can be added.

Despite the current writing speed being similar to downloading files from an Internet source that throttles you, I would be quite happy to have such a device, even with its current level of performance, to avoid worrying about paying periodically for new HDDs or tape drives, in order to migrate data from the old HDDs or tape formats.

pro with the 20$ subscription , from the gemini.google.com site , initially the request was routed to nano banana,

so I had to change the prompt and had to be very specific about not generating the image directly, here the exact prompt :

Not really. Unlike with physical goods like batteries, the hardware for training a diffusion vs an autoregressive language model is more or less exactly the same.

Although the lab that did this research (Chris Re and Tri Dao are involved) is run by the world's experts in squeezing CUDA and Nvidia hardware for every last drop of performance.

At the API level, the primary differences will be the addition of text infill capabilities for language generation. I also somewhat expect certain types of generation to be more cohesive (e.g. comedy or stories where you need to think of the punchline or ending first!)

(I’ve posted this before on HN but it’s worth repeating)

I’m an CAD hobbyist, and I’ve tried to work with FreeCAD multiple times over past years, always failing….

…until I saw this video and learned about version 1.1:

https://youtu.be/VEfNRST_3x8

FreeCAD is now in the same ballpark of capability and usability as Solidworks. It can still be a bit clunky and frustrating sometimes, but then so can most CAD programs, in their own ways.

Side note: the creator of the video above also has a video on optimising the FreeCAD interface. (There are some frustrations related to the interface generally, and this would seem to be a low hanging fruit for the FreeCAD team to address.)

Background: for decades the water management was handled by local govt, disastrously. Previous govt. (Ardern) fought like hell to wrestle this back to national govt, pushed it through as more systems were found to be on the verge of collapse.
The trumpkins that got elected next rolled this back immediately (“big bad central govt!”) and so now these water systems are collapsing, and the right wing is doing the GOP-style “oh yeah WE are FINALLY going to fix this”. Thanks Luxon you f’ing idiot.

But even if you combine Tier 1 and New Tier 1 Chinese cities alone, their populations are around 200M. That's close to 66% of the US. Besides Tier 2 cities like Xiamen, Hefei, Foshan and Zhuhai are still excellent.

So quantitatively, China’s pool is still very strong.

Not sure I understand you - what game, market capture? There are environments that remain more or less sane (e.g., FreeBSD, Xfce, etc) that don't play this game, if I got you right. I guess treating users so helps capture more of the market share, but it looks like there's only so much dumbfuckery one can inject into the environment until the curve begins to drop and dumb fucks themselves begin to run.

Philips just screwed up my TV. They've updated the firmware (of course, it was automated) to make home screen more of a dumb fucking experience with everything animated and self-playing movies jumping out at you for no reason, and so on... But the interface is now completely unusable - literally can't even launch YouTube. No amount of resetting helps. They also hid all the previous firmwares and I can't even roll back from a USB stick. I am a dumb fuck when it comes to TVs. And I will most likely be considering another brand next time.

Sure those are impressive. But they weren't sudden. It was already there before I was born and slowly evolved.

If I look at the most useful technologies around me, then Google Maps ranks high. But it wasn't sudden. It was on the desktop first. And then slowly crept through mobile.

LLMs on the other hand, suddenly just kind of appeared.

1. Goto pattern is very error-prone. It works until it doesn't and you have a memory leak. The way I solved this issue in my code was a macro that takes a function and creates an object that has said function in its destructor.

2. Defer is mostly useful for C++ code that needs to interact with C API because these two are fundamentally different. C API usually exposes functions "create_something" and "destroy_something", while the C++ pattern is to have an object that has "create_something" hidden inside its constructor, and "destroy_something" inside its destructor.

What strikes me about this discussion is how the talent flow has become bidirectional in ways we didn't see 20 years ago.

The US built its scientific edge partly on being the default destination for ambitious researchers worldwide. That asymmetry is eroding - not just because other countries improved their institutions, but because the friction of working in the US increased (visa uncertainty, funding instability, cost of living in research hubs).

The interesting question isn't whether the US can "win" the talent war, but whether the model of concentrating talent geographically still makes sense. Remote collaboration tools, distributed research networks, and global funding mechanisms are creating alternatives to the traditional "move to where the lab is" model.

Countries that figure out how to participate in global talent networks without requiring physical relocation might have an advantage over those still optimizing for immigration.

I don't know and can't speak for the team, but I suspect the "launching new products" is not a significant factor in the delays. It sounds to me like the delays are as a result of hardware manufacturing things (which maybe could/should have been planned for, but optimistically weren't), and that basically the alternative for the hardware folks would be a series of "sit on your hands for a couple weeks, then respond to the thing that came up" events, with the resulting delay for the PT2 being roughly equivalent whether they spend the intervening time designing new products or just waiting.

I think you're missing the point. That phrase isn't giving a direct instruction to the chatbot to make sure it doesn't get elected to congress and subsequently pass laws prohibiting speech. That phrase is meant to tell it "You should behave like those guys on twitter who really want to say the N word, but have no problem with Kash Patel bullying Jimmy Kimmel off the air.

The data in the chatbots dataset about that phrase tell it a lot about how it should behave, and that data includes stuff like Elon Musk going around calling people paedophiles and deleting the accounts of people tracking his private jet.

I can second Horizon EDA. It's not perfect, but it has the good KiCAD kernel without the abysmal UX.

FreeCAD may also be good - it's the only other one I haven't tried.

On the other hand if you're convincing EAGLE users to move they'll probably be happy with KiCAD because they're already used to an even worse UX, as if such a thing were possible.

The next thing after agent swarms will be swarm colonies and people will go "it's been a month since agentic swarm colonies, give it a month or two". People have been moving the goal posts like that for a couple years now, it's starting to grow stale. This is like self driving cars which were going to be workingin 2016 and replace 80% of drivers by 2017, all over again. People falling for hype instead of admitting that while it appears somewhat useful, nobody has any clue if it's 97% useful or just 3% useful but so far it's looking like the later.

It allows you to put the deferred logic near the allocation/use site which I noticed was helpful in Go as it becomes muscle memory to do cleanup as you write some new allocation and it is hinted by autocomplete these days.

But it adds a new dimension of control flow, which in a garbage collected language like Go is less worrisome whereas in C this can create new headaches in doing things in the right order. I don't think it will eliminate goto error handling for complex cases.

I think the big take away here isn't about misalignment or jail breaking. The entire way this bot behaved is consistent with it just being run by some asshole from Twitter. And we need to understand it doesn't matter how careful you think you need to be with AI, because some asshole from Twitter doesn't care, and they'll do literally whatever comes into their mind. And it'll go wrong. And they won't apologize. They won't try to fix it, they'll go and do it again.

Can AI be misused? No. It will be misused. There is no possibility of anything else, we have an online culture, centered on places like Twitter where they have embraced being the absolute worst person possible, and they are being handed tools like this like handing a hand gun to a chimpanzee.

I've just look out of curiosity on Appsmith, as the author endorsed this tool as some admin panel builder. I had to double check the name, as right now this is, surprise, surprise, AI powered application builder...

I used to use Replit for educational purposes, to be able to create simple programs in any language and share them with others (teachers, students). That was really useful.

Now Replit is a frontend to some AI chat that is supposed to write software for me.

Is this jumping into AI bandwagon everywhere a new trend? Is this really needed? Is this really profitable?

"No alternative" isn't quite right anymore, though I understand the feeling. The real problem with Datadog isn't the pricing - it's that their per-host model incentivizes you to care about infrastructure topology rather than user-facing behavior. You end up with 10,000 dashboards and still can't answer "is checkout broken right now?"

The open source stack has gotten genuinely viable: Prometheus/VictoriaMetrics for metrics, Grafana for viz, and OpenTelemetry as the collection layer means you're not locked into anyone's agent. The gap used to be in correlation - connecting a metric spike to a trace to a log line - but that's narrowed significantly.

The actual hard part of leaving DD isn't technical, it's organizational. DD becomes load-bearing for on-call runbooks, alert routing, and team muscle memory. Migration is less "swap the backend" and more "retrain your incident response."

If you're evaluating: the question I'd ask isn't "which vendor has the best dashboards" but "can I get from alert to root cause in under 5 minutes with this tool?" That's the metric that actually correlates with MTTR, and it's where most monitoring setups (including expensive ones) fail.

> Not using Function as a Service(FaaS) more

FaaS is almost certainly a mistake. I get the appeal from an accountant's perspective, but from a debugging and development perspective it's really fucking awful compared to using a traditional VM. Getting at logs in something like azure functions is a great example of this.

I pushed really hard for FaaS until I had to support it. It's the worst kind of trap. I still get sweaty thinking about some of the issues we had with it.

Your second point is the main argument for me personally. Numbers in brackets always mean the same thing: the ordinal number of the references object in an ordered collection. In 0 based indexing you can think of the number as refering to the space between the referenced objects. But that is simply an additional mental image on top of the original one.

As a neat bonus, in Julia 1:5 is just the iterator for the numbers 1 to 5. So slicing is typically not some special syntax either. It all works rather nicely.
