Show HN: I created a blender tutor that answers with visual cues
by gpopmescu | 2025-09-11 19:25:14+00:00
Hi HN,

When learning Blender I found I often end up spending too much time asking questions to ChatGPT and still having trouble locate where to click.

So... I created blender tutor that is like an LLM but can also find where to click to accomplish a given step when you try to for example enable auto save.

Ideal for beginners to finding out where to click and avoid searching through documentation and youtube tutorials!

For now it`s only a chat, but I plan to develop a next version where it will see what window/state you are currently in and help you better this way by showing you exactly where to click.

It will also be available for more softs like Photoshop etc.

Let me know if you think it will be useful :)

Thank you for your time! Happy to answer questions here.

Too bad that when it comes to reading for pleasure, "all signs show a slump"...

https://www.arts.gov/stories/blog/2024/federal-data-reading-...

Though I agree with you that a larger reading screen would be very nice, I doubt such an experience on a device that offers endless digital distractions will reverse this downward trend - not that you said it would.

With Microsoft specifically there's also the fact that it made a massive investment into rebuilding a large chunk of its campus in the last few years (IIRC it began before COVID). They demolished some of the oldest buildings - the ones that were done back when every senior engineer was entitled to an office of their own - and replaced them with "open office" cubicle farms.

Now, I would imagine that there are quite a few in the top management who originally signed off on that expense. Probably the same people who were talking about replacing offices with cubicles since 2015, which means Satya and his inner circle. So now they've spent a lot of money, they have to do something to show to the board that it wasn't wasted. Which means filling those buildings with employees, whether they like it or not.

If the person who taught you big-O notation didn't point out that for all practical values of N, log(N) is tiny, then they did you a disservice. It is indeed "practically constant" in that sense.

However, when someone says an operation is O(1) vs O(log N), it still tells you something important. Very broadly speaking (tons of caveats depending on problem domain, of course) O(log N) usually implies some kind of tree traversal, while O(1) implies a very simple operation or lookup. And with tree traversal, you're chasing pointers all over memory, making your cache hate you.

So, like, if you have a binary tree with 65000 elements in it, we're talking a height of 15 or 16, something like that. That's not that much, but it is 15 or 16 pointers you're chasing, possibly cache-missing on a significant amount of them. Versus a hash-table lookup, where you do a single hash + one or two pointer dereferences. If this is in a hot path, you're going to notice a difference.

Again, lots of caveats, this article provides a good exception. In this case, the sorting has much more beneficial cache behavior than the hash table, which makes sense. But in general, log(N) hints at some kind of tree, and that's not always what you want.

But yes, don't be afraid of log(N). log(N) is tiny, and log(N) operations are very fast. log(N) is your friend.

This is very encouraging, but will take a long time to get to any type of usable treatment because these cells are literally made to evade the immune system they run a whole bunch of other risks. Also cell therapies right now are one of the weakest markets in Biotechs due to the level of costs to develop. This is slightly different since it's Allogenic, but the market seems not very invested in cell therapy.

A swarm is actually a reproductive process. It looks like a mass of bees, but it has a specific purpose and composition.

(Although maybe you’re right colloquially)

https://en.m.wikipedia.org/wiki/Swarming_(honey_bee)

A load of bees engaged in robbing behaves entirely differently from a swarm, which is a magical thing to interact with.

1 - My main phone has a bunch of work stuffs on it and all my authenticator stuffs and etc

2 - I've been raided by the FBI before in my past (used to be blackhat in my 20s but now im whitehat :))

3 - I lose my phone sometimes. far better to lose a dinky burner phone VS my main phone.

It's obviously exaggerated for humor. Has no one ever told anyone else a story before? No one talks like this.

"Off-the-books" meetings are just friend-based connections. I got a bug in the Linux nvidia driver fixed that was affecting me by just hitting up an old friend. I could write that story as him saying "Keep this top-secret" if I wanted because that's just fun storywriting.

Loeliger's 'Threaded Interpretive Languages' jumpstarted my career in the late 1970s: I built a networked water management system based on their code, which was my first big project, earning me £1,500. Note that there's a bug in their code (I no longer remember exactly where) so getting it off the ground was tricky.

>I primarily blame Democrats

For the millionth time:

In the US, our democracy is purposely built to give the minority party almost zero power. If you have less than half the votes in both houses, you can't do anything, full stop.

Go look at how often Democrats have actually won votes. Americans choose not to vote for democrats and then blame them for not having power.

It's ignorance.

Republicans have run this country for 90% of the past 50 years. The public institutions failing have been purposely meant to fail by purposeful sabotage by republican politicians, who openly describe their tactics and publicly boast about "starve the beast", and people STILL blame democrats.

It takes way more time, effort, and public goodwill to build up or reform US government institutions, by design than it takes to tear everything down.

If you are still blaming democrats, you are part of the problem. Blame the politicians who have been voted in, democratically given the reigns of power, and have used that power for 50 or more years to make things worse.

Add to that, republicans have held the majority of State governments for the past 20 years.

It's utterly INSANE the lengths people will go, the stupid rhetorical lies they will tell themselves just to not have to say "The republicans have actively harmed this country for 50 years"

The US system intentionally does not give the minority party any power.

I didn’t miss their point, I challenged the foundation upon which it rested.

You are asserting that a free market is unstable and will inevitably lead to a monopoly. Even if I take this as a fact for the sake of argument, it doesn’t nullify my point that judging the intention of political action (antitrust laws to prevent monopolies) against the outcomes of a system (free markets devolve into monopolies) is comparing apples to oranges. You must judge the outcomes of both systems. As I stated in my original reply, regulations can actually lead to monopolies, so the outcomes matter a lot more than their good intentions.

If I don’t take your assertion as a fact though[1], then what you’re doing is judging what you believe to be the outcome of a free market with what you believe will prevent that through legislation. This is entirely too theoretical and doesn’t even begin to answer which is a better system. Ultimately we need to understand the actual trade-offs that are being made between these systems in order to select the system with the most desirable characteristics.

[1] It is not at all proven that a free market will naturally devolve into a monopoly. This has been a contentious debate in economics for centuries and is absolutely not resolved. People tend to assume a static market and extrapolate into the infinite future, e.g. if a horse drawn carriage manufacturer has 99% market share then will it forever be a monopoly in a broken system or will a fledgling automotive industry dethrone this “monopoly” with a better alternative that is not even a direct competitor? This is a really, really deep subject in either case.

Oh. Interesting. I had to look it up:

When :extend-via-metadata is true, values can extend protocols by adding metadata where keys are fully-qualified protocol function symbols and values are function implementations. Protocol implementations are checked first for direct definitions (defrecord, deftype, reify), then metadata definitions, then external extensions (extend, extend-type, extend-protocol).

(def component (with-meta {:name "db"} {`start (constantly "started")})) (start component) ;;=> "started"

Kind of a crazy feature.

This is very much in the Ha Ha Only Serious vein of humor: http://catb.org/~esr/jargon/html/H/ha-ha-only-serious.html

As someone who is not a Silicon Valley Liberal, it seems to me that "alignment" is about .5% "saving the world from runaway intelligence" and 99.5% some combination of "making sure the AI bots push our politics" and "making sure the AI bots don't accidentally say something that violates the New York Liberal sensibilities enough to cause the press to write bad stories". I'd like to realign the aligners, yes. YMMV, and perhaps more to the point, lots of people's mileage may very. The so-called aligners have a very specific view.

How strange that the article never links directly to the Helix editor. I usually immediately open the homepage of whatever a blog post is talking about as a background tab to be able to click back and forth, or to be able to immediately figure out what the thing being talked about is, but no luck here, except for some decoys (like the "helix" link next to the title which is just the tag "helix" which sends you to a page with all the posts tagged with "helix", which happens to just be this one post).

I of course quickly just googled it myself and found the page, and so afterward I went to the source of the blog post and searched for the URL to confirm that it wasn't actually linked to anywhere. Turns out that about three quarters of the way down, in the "Key Bindings" section, there is a link to the Helix keymappings documentation page, which appears to be the closest thing to a direct homepage link.

Anyways, no nefarious intent being implied of course, I just found it sort of interesting. I am pretty certain it just got accidentally left out, or maybe the project didn't have a homepage back in December of 2024 when this was originally written? Although the github page isn't directly linked either (only one specific issue in the github tracker).

Oh, and here's a link to their page: https://helix-editor.com/

And github page: https://github.com/helix-editor/

tl;dr This guy's AI software couldn't run on iPhones without damaging them. That's an iOS/iPhone bug. He believes Apple just put in a more advanced cooling solution into their latest phones because new AI software requires more cooling for the chips.

The whole thing is written in a bombastic storytelling style that is typical of LinkedIn threads. If this is entertaining to you, this is the link for you since it has actual image examples of their model output varying between platforms.

>> android also doesn't have the same polish as iOS

As someone who switched from using Android for many years to iOS for the iPhone Mini, this seems to be all about what you're used to. The lack of polish on iOS for many features, notifications and quick settings first among them, makes me crazy but not enough to deal with a huge phone. Android's had the notification shade with integrated settings since just about day one and it's a killer feature.

The Public Suffix List changes often. I have once worked with a team who built a major feature on top of PSL, but the person who built it did not at all consider how it might handle changes to it. Basically, the feature analyzed domains and uses PSL data to extract the "important part" of the domain, and then stored that in the database as part of a primary key in a table. But when the PSL changes, the database needed to be taken offline for certain tables to be completely rebuilt. And code querying the database had to be updated in lockstep with the database changes. This design made zero-downtime deployments difficult. It then took quite a while for the team to evolve the schema such that the database contents would not depend on the PSL.

This is just one cautionary tale I have personally experienced.

I’m of the opposite opinion, really: Automatic TLS certificate requests are just an implementation detail of software able to advertise as accepting encrypted connections. Similarly many applications include an OAuth client that automatically takes care of requesting access tokens and refreshing them automatically, all using a discovery URI and client credentials.

Lots of apps should support this automatically, with no intervention necessary, and just communicate securely with each other. And ACME is the way to enable that.

I have both a pair of the over ear Sony XM4’s and AirPods Pro 2 and I’m not sure I’d characterize the Sony’s sound as “better”, even when using lossless audio. They sound good but the sound profile is mostly just different, with the Sony’s leaning more bassy and the AirPods more balanced.

The noise cancellation are neck and neck but the AirPods had much less of that “pressure” sensation when using it. AirPods transparency is just plain better. Comfort for long use sessions is better on the Sony’s. Mic is better on the AirPods.

> Gabby Giffords assailant was pretty insane but reports from people that knew him claimed he was liberal

Unmasking myself a bit here but one of my college roommates at University of Arizona also attended classes with Jared at Pima Community College. Jared liked to burn flags, collect guns, and think the world was conspiring against him. The dude was insane (see his mughsot), not liberal.

You're misunderstanding, and it's a great opportunity for me to clarify:

I want a graphical installer for applications within NixOS.

Currently NixOS applications are added by editing the configuration.nix, with more specific tooling avaliable via flakes and home-manager. We agree that this is cool and good.

What I want for consumer use is NixOS, with an interal graphical installer that handles updating configurations in the background; ideally forming a no-terminal-necessary UX for consumer users.

The restrictions are not aimed at organisations, but to protect individuals.

https://www.gov.uk/government/publications/domestic-cctv-usi...

"If your CCTV system captures images of people outside the boundary of your private domestic property – for example, from neighbours’ homes or gardens, shared spaces, or from public areas – then the GDPR and the DPA will apply to you. You will need to ensure your use of CCTV complies with these laws. If you do not comply with your data protection obligations you may be subject to appropriate regulatory action by the ICO, as well as potential legal action by affected individuals."

You, as an individual, have data protection obligations, if your ring doorbell captures audio/video about someone outside your property boundaries. The apple translation service seems analogous.

This is great news. Any type of pancreatic function restoration is also potentially good for Type 1.5 (which constitute a sizable chunk of misdiagnosed T2Ds) where the body attacks more slowly (over the course of years) instead of acutely like traditional T1D and so doctors assume it's insulin resistance instead of pancreatic function decline since they both present with the same symptom - hyperglycemia.

It was surreal to see the lengths that bought corpo Dems and their media went to sink the Bernie Sanders campaigns twice, making it extremely clear they preferred Trump over Bernie.

The whole system is broken. It's overdue to launch our own publicly owned instance of what they built in Taiwan to sidestep political gridlock:

We posted the same thing, in essence, at the same time. This piece is completely nonsensical in every way, and I presume it is targeted at laymen who'll just go along with it. Like anyone who sees that last bit about MLX and CoreML and doesn't realize the author seems to not have a clue what they're talking about should understand they're being duped.

Apple adopted a new cooling technique on their highest end device to differentiate and give spec sheet chasers something to be hyped about. It should help reduce throttling for the very odd event where someone is running a mobile device at 100% continuously (which is actually super rare in normal usage). It's already in the Pixel 9 Pro, for instance, and is a new "must have". It has nothing to do with whatever app these guys were building.

The rest of the nonsense is just silly. If you are building an app for a mobile device and it pegs the CPU and GPU, you're going to have a bad time. That's the moment you realize it's time to go back to the drawing board.

Some people will probably call you a luddite, but don't listen to them. There's nothing wrong with taking joy in the craft, with learning and exploring and creating. That's what hacker culture used to be about.

Unfortunately, you won't be able to get a job in software with anything but AI skills, since humans no longer write software in the industry. People will look at you the way they used to look at anyone who wrote their own HTML or Javascript without frameworks and Typescript, like you must drive your car to work with your feet.

Binet's (or Euler's or de Moivre's) formula for the nth Fibonacci number is (((sqrt(5)+1)/2)^n-(-(sqrt(5)+1)/2)^-n)/sqrt(5). Additions are O(n). Multiplications vary depending on the algorithm, the best known (Harvey-Hoeven) is O(n log(n)) but comes with some nasty constants that probably mean classic Karatsuba or Toom-Cook multiplication (O(n^1.X) for some X will be faster for the range to be graphed, but I'll stick with O(n log(n)) for this. The exponentials will be O(n log(n)^2) in the best known case IIRC. That factor dominates, so I'd say it's probably O(n log(n)^2) but that a graph probably won't start cooperating quickly due to the algorithms picked having factors that are ignored by big-O notation for the small inputs given.

However you do it it probably can't be linear, since multiplication is probably at best O(n log(n)), though that lower bound hasn't been proven. A naive recursive calculation will be even worse since that has exponential complexity.

The reason that the KDC doesn't decide if the user should get a ticket is that then the power requirements of the DC would be enormous. It should have to know if a user is supposed to have access to every single service in the environment. It would be a massive database. That massive database would also have to sync to all the other DCs. To alleviate this, Kerberos let's the server decide if the user has access, and if so, how much

I don't think attitudinal surveys are of much value here. If you ask someone whether they support murder very few are going to give you an affirmative answer. Even people who advocate for political violence will jump through wild rhetorical hoops when challenged about it, eg arguing that communists aren't people and therefore killing them isn't murder.

I think it's better to look at the actual incidence of violence than to extrapolate from weakly correlated leading indicators.

How do you reconcile being an immigrant coming to a country. And then supporting the foundational document of the country be changed or overruled by decree (14th amendment) against the will of the populace . And then whine about the law and papers?

If we should be deporting anyone it should be immigrants like you how seem to want to change the culture and meaning of "American"

> Is it that these were hundreds of the best battery factory professional engineers in SK or just a cultural match?

SK has been building battery factories for a while, naturally, they ended up with an experienced talent pool.

> How is competence built with any offshoring of a new thing?

China has the blueprint: enforce knowledge sharing/knowledge transfer to local entities, and provide adequate direction and government funding.

> I think it’s a stretch to say Americans can’t be trained to make a factory.

Experience =/= capability - Americans certainly can be trained, but who's paying (and waiting) for that? Does it make economic sense to do so for a one-and-done project? LG Chem (and its vendor ecosystem) have been building battery factories for well over a decade now, and will continue to use that competency. What would happen to your hypothetical newly-trained, all-American battery-factory builders once the Savannah project is up and running? Especially under this administration that is set on cutting the knees from under renewables.

The ICO is pretty zealous though in this regard. To quote recital 18:[1]

This Regulation does not apply to the processing of personal data by a natural person in the course of a purely personal or household activity and thus with no connection to a professional or commercial activity.

It seems quite reliable that Bluesky gets down voted. Whether it's mastodon/Fediverse folk or right wing pro twitter philes or both, I dunno, but it sucks to have aggressors out there, dark forest freaks sniping away.

I try very hard to find the positive & to upvote things I don't fully agree with, if well argued. I wish the social network of HN could do more against adversarial zero-sim thinking, didn't have people who insist on draining.

I'm against murderers and I'm against agitators (which is just about synonymous with influencers in politics). Kirk did a lot of damage. And whoever did this did a lot of damage too. I'm not sure about where the balance between those two lies but it irks me that you're supposed to be either on the side of the murderer or on the side of Kirk with zero room for more complex viewpoints. What irks me even more is the cynical way in which the usual suspects have already decided this is what they needed to further their agenda.
