Lots of ways to start. None of them are wrong. Just let your passions lead you to something you’d like to explore. Maybe start with a hackable 3D printing kit that will let you build parts for more robots. Hacking the 3D printer can directly teach you a lot about robotics.

https://simplefoc.com/ Is my type of rewarding nerdy topic. You might be more attracted to other control strategies.

Mastering robotics as a DIY thing is usually more about the mechanical (particular linkages and kinematics) as well as electrical (particularly motor control). The programming part of it generally can be lower quality and more hacked together, but still can be an area of deep exploration if that’s your passion.

https://youtu.be/pJj6uGcMco4?si=J0ui8LzYxEBXePZ0 ‘Engineer Bo’ is a small YT channel with a few great videos about stepper motor control. This video is about protecting the motor driver chip from large surges of electricity when the motor tries to wuickly “brake”. There’s a second video where he iterates on this solution.

If you don't find the mechanical and electrical parts something you want to invest enough time in to learn, and want to just dive into the programming side, then you could focus on simulation entirely. In that case, look into MuJoCo or OpenAI Gym (ported and maintained by community as ‘Gymnasium’).

Don’t be afraid to ask LLMs to help you learn. They might lie to you or occasionally send you down a non-optimal path, but they’ll be helpful first exposing you to so many of your current blind spots and helping understand the scope of any endeavor you might be interested in.

You can still buy brand new LTO-4 and up from a brief search - I think due to the enterprise use cases it’ll hang around longer than any other format. Tape existed before the HDD; it’ll be there watching HDDS pass away into the ether too. Probably a few tape drives on the Starship Enterprise somewhere.

More seriously; you can buy used lto-7/8 for very little these days, and the tapes are extremely cheap per gb. The drives are somewhat loud; it’s not a beside device for sure. I’m finding it a bit of a pain to manage a good backup strategy with them.

There should be two separate lines of products. One in which privacy is priority and adheres to government regulations (around privacy) and probably costs 2x and one with zero government intervention (around privacy) which costs less and time-to-market is faster.

I don't want a few irrationally paranoid people bottlenecking progress and access to the latest technology and innovation.

I'm happy to broadcast my brainwaves on an open YouTube channel for the ZERO people who are interested in it.

You can actually make go spit out .o files and link it with your favorite linker. Bazel does this, if you ask it to.

I played a lot with experimental linkers when I was trying to get build time down for our (well, $JOB-1's) large Go binary, but they didn't help that much. The toolchain that comes with Go is quite good.

This argument doesn’t make sense to me. Generally speaking, having more registers does not result in more spilling, it results in less spilling. Obviously, if you have 100 registers here, there’s no spilling at all. And think through what happens in your example with a 4 register machine or a 1 register machine, all values must spill. You can demonstrate the general principle yourself by limiting the number of registers and then increasing it using the ffixed-reg flags. In CUDA you can set your register count and basically watch the number of spills go up by one every time you take away a register and go down by one every time you add a register.

Because I know javascript a lot more than I know Lua (and I suspect given js popularity, a lot of people are in the same boat). Yes Lua is easy to learn, but it's still different enough that there is friction. The differences also aren't just syntactically, it's also libraries/APIs, and more. I also don't have any need/use for Lua beyond neovim, so it's basically having to learn a language specifically for one tool. It's not ideal for me.

But the people who did the work wanted Lua, and I have no problem with that. That's their privilege as the people doing the work. I'm still free to fork it and make ruby or js or whatever (Elixir would be awesome!) first-class.

If you’re talking about this post, it’s just someone who was misinformed. https://www.reddit.com/r/DataHoarder/s/cmxnECtgAv

> Verbatim clarified that these discs were advancements. The technical changes resulted in a different appearance and the ability for higher burning speeds, the changed media-ID was due to an adaptation with regard to other Verbatim products. Verbatim had already shipped the first modified media in early 2022. The data security of the new discs is not inferior to that of the old discs: Data should also last 1000 years, according to the manufacturer.

Not a neuroscientist either but I would imagine that raw data without personal information would not be useful for much. I can imagine that it would be quite valuable if accompanied with personal data plus user reports about how they slept each night, what they dreamed about if anything, whether it was positive dreams or nightmares etc. And I think quite a few people wouldn’t mind sharing all of that in the name of science, but in this case they don’t seem to have even tried to ask.

That's a very good response. I agree completely.

> Thus, regulation does not give people more freedom, it can however reduce harm.

When I say regulation is freedom, I'm borrowing from dialectics. The only way we figured out how to move forward is to leave something behind.

So when you see regulation, the absence of a given right, let's say to carry a deadly weapon in public, you have to see this is the tailend of the synthesis of a long debate, where we agreed that the risks of arming the population outweighs the benefits of self protection.

So regulation is freedom because freedom is choice, and to choose is to leave something behind. Regulation is just the manifestation of the consequences of that choice.
Show HN: MirrAI – I built a Virtual Try-On app to fix online shopping(Open Beta)
by MohammadRMZ | 2026-02-14 17:40:49+00:00
Hey , My name is Mo. I’m an indie developer and I built MirrAI because I honestly get frustrated buying clothes online. You wait a week for delivery, try it on, and realize it looks nothing like it did on the model.

So, I built a solution.

*MirrAI* is a mobile app that uses generative AI to let you virtually "try on" clothes. You upload a photo of yourself, pick an item (upper body, lower body, shoes, etc.), and the AI attempts to blend the new outfit onto your body while keeping your pose and lighting natural.

It’s not just a standard image generator; I’ve focused heavily on the "Fit Check" aspect to make it actually useful for styling.

*Current Status:*
We are in *Open Beta*. It’s definitely not perfect yet (fabric physics are hard!), and you might see some funny glitches with complex poses, but it’s functional and fun to play with.

*I’d love your help with:*
1. *UX:* Is the flow of uploading/selecting clothes intuitive?
2. *Quality:* How convincing does the "try-on" look to you?
3. *Bugs:* If it crashes or makes you look like an alien, please let me know!

Thanks for checking it out. I’ll be hanging around in the comments to answer any questions!

– Mo

This exactly.

Politics on Ars makes me think of the Sports Illustrated swimsuit issue. At some level of the decision making process for the publication you have to suspect that not only is being done just for engagement but also that there's no respect for the audience.

Ars is more complicated - I mean, RFK jr. comes out against vaccines - is that sciency or politics? Both? But ultimately they're just playing to the audience in the worst way.

My language was sloppy, but I'll admit I thought it was pretty obvious that we were talking about defining the rest of the reals starting from the rationals -- obvious enough that it didn't need clarification. I can't edit my prior comment, but you may imagine it has been amended in the obvious way with that clarity made explicit rather than implicit and reply to it again if you're interested in continuing the conversation.

It's so strange, when I switched to Android, it felt like iPhones had more polish and fewer glitches like these. But there's just aren't any usability bugs that I deal with on Android anymore.

I think the blog explains why people put up with such a buggy OS:

Well, they're more aligned with Larry Ellison's than they are the CCP, even if they're probably not all that aligned.

Separately I don't particularly care who owns TikTok. I've never used it. But if someone is going to own and people are going to voluntarily subject themselves to these algorithms and the owners intentions, it I'd prefer it to be Americans (or another western country).

I like this aphorism someone once stated on bothsides-ism: When an arson burns down your home you don't pause to consider their side of the situation. Standing up to a bully doesn't mean the bully is being treated unfairly. They're just not accustomed to pushback on their BS and quickly don the caul of victimhood whenever their position is exposed.
Show HN: OpenCode-finance – prompt a ticker, get a structured PDF analyst report
by bilalbayram | 2026-02-14 17:42:37+00:00
OpenCode Finance — `/report <TICKER>` generates a delivery-ready PDF equity research brief

Prompt in. Equity research out.

I built OpenCode Finance (opencode-finance), a finance-focused fork of the OpenCode terminal agent runtime. The goal is to make “repeatable analyst reports” feel like a single command instead of a multi-hour docs + spreadsheets + copy/paste workflow.

The core workflow is:

/report AAPL
and a few minutes (seconds when you use 5.3 Spark) later you have a polished PDF report + the underlying artifacts on disk

What makes it different from “chat with a finance bot” is that the output shape is intentionally rigid and consistent across tickers, and the report is assumption-first:
- Observed data is labeled as observed; non-observed claims are explicitly labeled as inference.
- Sources are attached inline (URLs + retrieval timestamps in the report).
- There’s an assumptions ledger so you can audit what the model assumed vs what it actually fetched.

How it works in practice:
- You run it locally in a terminal TUI.
- `/report` runs a strict preflight; if you’re missing required provider credentials it automatically drops you into onboarding so you can finish setup and rerun immediately.
- Output is a clean PDF “artifact” you can hand to someone, plus markdown/JSON artifacts for review and iteration.

Install + quick start:

curl -fsSL https://opencode.finance/install.sh | bash
/onboard

Sample PDFs:

https://www.opencode.finance/reports/AAPL-2026-02-14.pdf

https://www.opencode.finance/reports/TSLA-2026-02-14.pdf

https://www.opencode.finance/reports/LLY-2026-02-14.pdf

Code + docs:

https://www.opencode.finance/

https://github.com/bilalbayram/opencode-finance

A few quick notes:

- Not investment advice. The report is meant to separate observed data from assumptions/inference and be auditable.

- Runs locally; tool actions are permissioned and provider credentials are stored locally via `opencode-finance auth`.

- `/report` is designed to be reproducible: fixed structure, consistent sections, and a PDF output suitable for sharing.

I'd argue that Wikipedia and its 'sister' projects have accidentally cannibalized a sizeable fraction of the former 'non-commercial, non-business focused' Internet of the 1990s and early 2000s. If you're providing information in a way that's not intended to further some sort of profit motive, it makes sense to work within that large established project because that maximizes the resulting exposure. The rise of LLMs only makes this starker, every LLM is trained from Wikipedia.

I read ars technica during undergrad over 20 years ago now. It complemented my learning in cpu architecture quite well. While in class we learned old stuff, they covered the modern Intel things. And also, who could forget the fantastically detailed and expert macOS reviews. I’ve never seen any reviews of any kind like that since.

I dropped ars from my rss sometime around covid when they basically dropped their journalism levels to reddit quality. Same hive mind and covering lots of non technical (political) topics. No longer representing its namesake!

> I don’t think the CEOs are fully aligned culturally with Trump

Does it matter? If all their actions are in support of a regime, does it matter if they secretly don’t agree with it and don’t even say it? Does it matter that your neighbour says they don’t agree with ICE of they still rat you out to them? Ideologies without action aren’t worth much. At this point, we should assume these CEOs are fully on board with and support Trump’s policies. There’s no reason to make up excuses that they might not be when they repeatedly demonstrate the opposite.

As an aside, it seems cool that the bar to reverse engineering has lowered from all the LLMs. Maybe we'll get to take full control of many of these "smart" devices that require proprietary/spyware apps and use them in a fully private way. There's no excuse that any such apps solely to interact with devices locally need to connect to the internet, like dishwasher.

Thanks for this post. Sometimes you need a relatively simple tool for controlling a problem. I think this is something that I need to employ here on my place.

I have a problem with deer. My property is effectively an interstate highway for them with lots of delicious grazing available in my native grass pasture and in my orchards and gardens. I have fenced the important areas where we grow our food using deer fencing and it is effective. It does not stop the traffic though, it merely redirects it. I want the deer to avoid my property and using the scented repellent products is ineffective.

I bought a slingshot with a bunch of mudball ammunition and started using that every time I found them over the fence on my property. It is effective enough that you can make them leave if you tag one of them. After a while, they recognize the sound of the slingshot release and will trot off a little ways to buy time to determine whether there is an issue. Aiming and hitting targets is not hard and your skills improve over time so that it is pretty easy to score on 80% of targets in no time. The real problem is the effective range of the slingshot. For deer more than 50m from you the ball has lost most of the energy and when it thumps on the deer the usual result is that the deer raises its head from the grazing and looks around to locate the source.

I think a sling will be the next tool that I employ to make them graze someone else's property. The improved range should help me keep them on the other side of the fence.
by bee_rider | 2026-02-14 17:46:16+00:00
I agree with you.

One little thought is, has there been much drama between the vim and neovim communities? (I guess community can be defined broadly enough that the answer to that question is always “yes,” but I haven’t seen much). They both seem completely happy to just do their own thing. I think the perennial argument just exits in the mind of some fans.

It is nice to see a pair of projects with so much potential for competition coexisting peacefully. Plenty of room on the internet I guess.

If it was truly a private chat, there is no sealion.

That's why my perspective on this is that it is precisely about the expectation of privacy (even when in a factually non-private context), or as you note a clear division between participants and observers.

And that's why I think there's a cohort/age-based aspect to this: early users of the internet never had any concept of privacy in general, other than for email.

As always with the surveillance industry, your experience may vary. I'm sure there are workarounds, less-hassled IPs you can get access to, etc. The point is that going for the straightforward libre software solution lets you avoid playing any of those constantly-churning games to begin with.

I like the idea of some kind of algorithm minimalism, or at least parsimony; but I also think sometimes it might be appropriate? In this case, another approach would simply be randomization, which doesn't favor any name (Aaaaaron Aaaaanderson's blog :P ), this randomization can be consistent (such that you can find something you wish in linear time).

I think equally important is algorithmic transparency, that is, that the algorithm be publicly disclosed (although I think simplicity is a component of transparency: if you just dump a huge incomprehensible algorithmic mess somewhere that's not very helpful), so that you at least know what you are getting into, and better yet have some ability to choose and make educated critique of the current state of things (i.e. does the algorithm just maximize engagement like a slot machine? or does it optimize for some kind of helpfulness?).

Yeah 100% this. I want to watch Endeavour without ads, and I couldn't get some of it on Bittorrent (which is a first). It's available on ITVX for a subscription but there's literally nothing else I want to watch on there and I don't want to deal with cancellation & time pressure to watch it all.

I did consider buying a Blu-ray player and buying it on Blu-ray but it seems like they never actually released all the series on Blu-ray.

In the end I ended up figuring out how to download it without ads from ITVX. There's a tool which will bypass Widevine, download all the segments and splice them together without ads. Quite a pain to get working but still less annoying than yet another subscription. We already have Netflix, Disney, Prime, and a TV license.

Hey everyone,

Wow, you scooped us! we weren’t really expecting to launch here just yet, but happy to answer any questions y’all have :)

First, Pierre is building code storage for machines -- think GitHub’s infrastructure layer, but API-first and tuned for LLMs.

What does that actually mean? We’ve spent the last 18+ months speed running GitHubs infrastructure (with a lot of help from early GitHub folks)… this is Github’s spoke architecture with a few modern twists + object store for cold storage.

Up until this point, GitHub is the only team that’s built a truly scalable git cluster (gitlab, bitbucket, etc. are all enterprise plays, with different tradeoffs).

Code.Storage is meant to be massively scalable… and we’ll be doing a larger post on what that means, and the scale we’re already doing soon hopefully :)

On top of this, we’ve invested a TON of time into our API layer – we have all the things you’d expect, list files, create branch, commit, etc. – with some new api’s that agents have found helpful: grep, glob based archive, ephemeral branches (git namespaces), etc.

Right now we’re in private beta – but happy to do my best to answer any questions in the short term (and if you’re working on anything that might benefit from code storage or storing code like artifacts – please reach out to jacob@pierre.co

It is that deep and 'I was just joking' ironic misogyny is still misogyny.
This is the process of normalization. You go from 'edgy' to true believer without ever noticing a sudden shift.

It is how we got from 'ironic' nazis forums online 30 years ago to practicing nazis

Yes, but also... that's like 90% of the interactions you get on the internet?

I don't want to be too meta, but isn't that a description of most HN threads? We show up to criticize other people's work for self-gratification. In this case, we're here here to criticize the dev caving in, even though most of us don't even know what Stoat is and we don't care.

Except for some corner cases, most developers and content creators mostly get negative engagement, because it's less of an adrenaline rush to say "I like your work" than to say "you're wrong and I'm smarter than you". Many learn to live with it, and when they make a decision like that, it's probably because they actually agree with the mob.

To expand on that: B5 is about ethics, and it has a primordial good and evil that are decidedly kept in the mystical realm. It has a supernatural concept of souls, it has messiah-like characters, it seems to believe in a notion of fate. TNG on the other hand is steeped in renaissance enlightenment, it has the spirit that there is no supernatural, and that everything is rationally explainable. It often tackles ethics as well, but I dare say that beyond that it explores a broader territory in philosophical topics than B5. TNG is more down-to-earth, B5 is more vibe-heavy.
