vvilliamperez··on AI-generated posters don’t have to be horrible
This is the classic client vs designer disparity.

Here, client makes it with AI vs designer making it with AI.

The client doesn't really know what they want, or how to ask it properly. The designer is the one with taste, and the client pays for that.

Designers find flaws in the AI outputs, because their taste is high and prefer to just make it themselves.

(Not even touching on the hornet's nest of ethics of how these models are trained)

It's not exactly correct. Photography is just as much an art, but it's a very different medium and pieces are judged differently.

Realism isn't difficult, so critique shifts towards composition, narrative, context, process, and emotional impact.

Taking a clear photograph is easy with modern equipment, which means the bar for what's considered "good" is high.

I bought one from a machine easily at a train station. It spits the card out for you.

Once I downloaded it, it made sense. The blog post almost made me cancel my subscription because it seemed to get rid of the IDE entirely.

I just use open claw as a local memory management system. Not sure from TFA what's new here.

Actually their payment model has some baked in niceness.

If you don't use the service in a month, they just refund you. This has kept me from unsubscribing for years now. Some months I use it, some I don't.

It's more of hassle to unsub, and re-sub again when I want.

They could be priming users for a transparent interface, like a transparent iPhone. Or glasses.
vvilliamperez··on Take the Pedals Off the Bike
I ride and work on motorcycles a lot.

tl;dr: Front wheel fork angle causes uprightness, the overall cause of turning is due to tire shape and contact patch at lean. Countersteering is the input to start and maintain leaning.

Bicycle and motorcycle physics have a lot of different forces at play, but the main one for keeping the bike upright is the front wheel, causing corrective steering at lean.

When a bike starts to fall, the rake angle causes the wheel to "self correct" and steer the bike towards uprightness. With speed, the bike wants to stay upright and will self correct.

To steer at low speeds (most bicycle speeds), you actually turn the wheel in the direction you want to go very briefly, "fall" into a lean and switch quickly to counter steer in the other direction, keeping the bike upright.

At high speed it's a bit different. You don't need to initiate the turn. You can just skip straight to counter steering, which forces a lean and causes a turn. At speed you are constantly upright, so you need some input to tilt the bike.

The effect of leaning to the right with the wheel self-correcting left, is an overall arc to the right (vise versa).

As for gyroscopic forces, these are at play but the force is negligible for keeping the bike upright. Heavier wheels have higher angular momentum, making the bike a bit harder to force a counter steer. They also affect how quickly a bike can accelerate given a certain force.

vvilliamperez··on How I got scammed on Facebook Marketplace (2023)
I just had a Facebook marketplace camera scam happen to me Today.

Seller marked as shipped, and delivered, but my package wasn't there.

After some sleuthing (I knew a guy who works in UPS) the seller put a different ship to address. So Facebook marketplace isn't doing something as simple as verifying the tracking label is heading to the right destination.

Only doing E-bay from here on out. They have this problem solved for the most part.

"Z-pak" is a dosage of the antibiotic Zithromax, or Azithromycin, taken as a "pack" of pills over the course of 5 or more days.

I'm guessing backed up means constipated

Took me a bit to understand at first, but now I read it as `engineer`
vvilliamperez··on Tell HN: Twitter switched temporarily to rate limited mode
Could be they are trying to identify bots. Real users will probably leave the app/website on rate limit hit.

Yes other companies have animations but they make sure it performs well across browsers and OSs.

Mac+Firefox users are probably in your customer base. Listen to the feedback.

vvilliamperez··on Apple Vision Pro: Apple’s first spatial computer
Apple is taking small but important steps here. Notice how most of the content is 2d rendered onto a plane in 3d space.

Meta and previously Magicleap perhaps bit off more processing than they could chew with 3d models in a 3d world mesh.

vvilliamperez··on Help make mass surveillance of entire populations uneconomical
Not legal.

The problem with conspiratory talk is that while one person may fully not intend on action, it could inspire and/or manipulate others into committing acts. The blame is shared on all for conspiring and creating that environment where acts can emerge.

Nurbs are not efficient for realtime rendering.

There's no reason to encode all that curve data if all you care about in the end is a finite set of pixels rendered on the screen.

You can achieve the same level of detail without having to recalculate the surfaces. It's a lot easier for the computer to morph a shape by applying some math function (that's essentially arithmetic) to all the polygon's vertexes.

That said, I've seen some 3d artists work in NURBs, then render out to Polygons.

Oh in the last line of your original post, you said you think we will gravitate Towards working from home. Typo?

Edit: OP edited to correct the confusing typo

Is this a chat-GPT response? No offense, I'm just confused by the line of reasoning.

vvilliamperez··on Japanese explained to programmers
Yeah that's the link what I was referring to, I forgot to add context.

What I meant was if Matz "trying to make Ruby natural, not simple" was due in part to the way the language is spoken.

This style of sentence structure was one of the strangest things to get comfortable with. You have to think a bit differently.

The function chaining makes sense here and I wonder if the language had influence on Ruby's development.

Anyone interested in the language should definitely check out the Genki series. It's written well enough you could fully teach yourself.

vvilliamperez··on Ask HN: How to move from traditional tech into game dev?
Almost all indie devs these days use Unity or Unreal. You'll get more output out of these quicker, and that will encourage you to continue developing.

Don't be put off from writing your own engine, but it is quite a daunting task, expecially for 3D.

Besides rendering, these off the shelf engines provide tooling that make game development easier on you. Map editing, animation editing, sound editing etc all built in.

It works. It's basically a software brute force that works great for 4 digit pins, takes longer for longer passcodes. Other offerings are a keylogger for the pin/passwords after they "return" the device to the suspect.
