rgovostes··on I extracted the safety filters from Apple Intelligence models
Is this related in any way to Core ML model encryption (https://developer.apple.com/documentation/coreml/encrypting-...)? I find that feature a little bizarre because Apple has historically avoided providing any kind of DRM solution for app asset protection.
rgovostes··on Show HN: I wrote a "web OS" based on the Apple Lisa's UI, with 1-bit graphics
The shadow text style and fatbits editor in the Preferences app really took me back. Other than a lack of close buttons on windows, it's remarkable that you can strip away 40 years of UX "innovation" and the result is still productive and intuitive.

(Edit: Menus staying open after one click was a welcome improvement that I think came much later.)

rgovostes··on Show HN: I wrote a "web OS" based on the Apple Lisa's UI, with 1-bit graphics
I had the same reaction, but it's intentional. Open the Preferences app, check Decorate Desktop, and then select something other than Pale Blue Dot from the color palette picker.
rgovostes··on bootc-image-builder: Build your entire OS from a Containerfile
Roman Shtylman has an example of using a Dockerfile to produce a rootfs for the Jetson Nano: https://github.com/defunctzombie/jetson-nano-image-maker (2022)

I've always been hesitant to use this method over debootstrap: the Ubuntu container images ("FROM ubuntu:20.04") are created from a tarball that Ubuntu's convoluted CI system spits out and I'm not confident I understand if it's somehow suitable only for a container and not for real hardware.

rgovostes··on macOS Tahoe forces all app icons into iOS squircles
I'm an icon snob myself, and have fond appreciation for the glossy 3D icons of Mac OS X's past—the Pages inkwell, the "Here's to the crazy ones" easter egg in TextEdit, etc. I abhor the minimal-effort iPhone Mirroring icon in Sequoia.

I think the automatically generated icons for your apps look completely fine. And basically all of the examples you showed. You could remove the border on Bonjeff or add a background color to Underpass (or any of them) if you really wanted. If I had StopThe* side by side in my Dock, I would probably wish the octagons were the same size, but they might not have been to begin with?

(My favorite icons might be in Books.app → Book Store → Sections.)

rgovostes··on macOS Tahoe forces all app icons into iOS squircles
> The macOS Tahoe app icon squircling is a pain and a cost for indie developers like me and the others shown above.

No? The system provided you with an icon. You aren’t obligated to redesign anything.

It’s fair to disagree with the aesthetics of the new style or usability of losing unique silhouettes or readability of shrinking icons down to fit in the squircle, but it isn’t creating any obligation for indie developers.

rgovostes··on WireGuard vanity keygen
For vanity GPG keys, I came up with a neat trick where you could insert arbitrary ASCII art into your key. You construct your ASCII art using the Base64 character set. The decoded binary will be gibberish but you can place it in an inert Literal Data Packet that will be ignored by any conformant OpenPGP parser. It just takes a little finagling to align your data to a 3-byte boundary with appropriate line wrapping.

rgovostes··on I bought a $1k electric boat from China. Here's what showed up
The article mentions it cost 5x the list price; was almost a foot shorter than described; lists to one side; has uneven fiberglass and a cheap, inefficient propeller; reaches only 2 knots; and that the author doesn’t “think it’d be a safe” in “decent current”. Hell of an ad, if so.

Yes! You can select “remember my choice” but it won’t. Evil.
rgovostes··on Sapphire: Rust based package manager for macOS
As described on https://docs.brew.sh/Installation#untar-anywhere-unsupported:

> Technically, you can just extract (or git clone) Homebrew wherever you want.

However, Homebrew maintainers are dickish about essentially banning you from contributing to the project if your installation is nonstandard. They have a similarly discouraging warning if you are running a developer beta, which has turned me off of contributing fixes to broken formulas lest they reject them.

> If you decide to use another prefix: don’t open any issues, even if you think they are unrelated to your prefix choice. They will be closed without response.

rgovostes··on Marching Events: What does iCalendar have to do with ray marching?
I was really hoping this was going to be a demonstration that the recurring event frequency field is Turing complete by implementing a ray tracer in it.
rgovostes··on Dockerfmt: A Dockerfile Formatter
As far as I can tell from https://github.com/moby/moby/issues/4032, as of Debian 12 "bookworm" and Ubuntu 23.04 "Lunar", explicitly setting DEBIAN_FRONTEND is no longer necessary.
rgovostes··on Let's Ban Billboards
Boston sells off every square inch of public bus stop, trash can, etc. to a small number of companies that pay a pittance for the right to resell the space for advertisements. Lexington and Concord are the only places where such things are disallowed.

During the pandemic I found a trash can in a suburb that had been postered with a Johnnie Walker ad for over a year, and sent in a phony request for a quote to advertise a community poetry slam event. The quote was for over $2000. Multiply that by every trash can in the city.

rgovostes··on AnimeJs v4 Is Here
Are there authoring tools available, as with Lottie, or is it code-only?
rgovostes··on Why Is This Site Built with C
Many tools in the web publishing world are fixated on build speed. I would think transformations of text into templated HTML ought to be basically instantaneous on modern CPUs and SSDs, even for slow interpreters, for websites of even substantial size. It doesn’t exactly require algorithms with quadratic runtimes.
rgovostes··on The Myth of Liquid Detection
Apple provides a man page for every system daemon. I suppose this doesn't answer too many questions though:

    NAME
      liquiddetectiond – Liquid Detection and Corrosion Mitigation Daemon

    DESCRIPTION
      liquiddetectiond runs in the background and collects liquid detection
      analytics from each USB-C port on the system.
rgovostes··on I Turned Off Apple Intelligence – Sad Update
Today Facebook Messenger sent me a second notification about a message because I hadn't responded to the first one 6 hours earlier. They are hell-bent on making the experience as miserable as possible to drive engagement.

The rule about promotional push notifications being opt-in still exists in the App Review Guidelines, it may just take some public shaming to get Apple to enforce it.

(While many apps from big publishers skirt the rule, DoorDash is the most egregious I've noticed: if you opt out of promo notifications, they'll try to trick you into turning them back on every time you place an order, suggesting that you won't receive delivery updates otherwise.)

rgovostes··on Leaked Apple meeting shows how dire the Siri situation is
My speculation is that the small on-device models are simply not useful enough for practical purposes.

The on-device transformer models are described as having 3B parameters[0]. Their own figures from 6 months ago show that humans prefer other models' output 25-40% of the time, which aligns with Gurman's reporting.

I don't know how well Apple's A-series chips can handle transformers, but if you play with their on-device diffusion models (Image Playground, Genmoji), you can watch your battery drop before your eyes. And the output of these models is also embarrassingly behind the state of the art.

If Apple can make great foundation models for Private Cloud Compute, that's great. But then what's the point of buying a new iPhone for on-device inference capabilities?

Secondly, I speculate that allowing a server-side model to query the personal context database is going to be hard to do performantly, requiring several round trips and uploading fragments of the data to the cloud for processing.

rgovostes··on Comet open source remote KVM from GL-iNet
Has existed on decades, just requires the simple process of turning it on in your BIOS, then changing your network adapter advanced settings in Windows to Wake on Magic Packet, and configure the power management settings to "allow this device to wake the computer", etc... It's like a 20 step process.
rgovostes··on Discovering errors in Donald Knuth's TAOCP
I haven't read TAOCP myself, but if I recall a lecture that Knuth gave, his algorithm analyses sometimes include cycle counts for his virtual MMIX architecture. He mentioned that these are counted by hand. If I were seeking a reward check, I would write a verifier to look for errors there.
rgovostes··on Dear Apple: Add "Disappearing Messages" to iMessage
There sort of are "burn after reading" voice messages. After they're played once, they're removed after 2 minutes.

The recipient can tap "Keep" to permanently save the audio. This returns to the sender the prone-to-misinterpretation warning, "So-and-so kept a message from you."

The "Keep" function is actually an important signal here to the user that breaks the expectation that disappearing messages are unassailable. The recipient can always make a copy.

rgovostes··on Global sales of combustion engine cars have peaked
I deliberately rented a Kia Niro EV on my last work trip for the novelty of driving an electric car since probably 2016. I even insisted when they tried to switch me to another vehicle.

Boy, it sucked. Even with a Type 2 charger at work, and maybe 2 miles between the office and my hotel, charging was a huge hassle. And with an ICE vehicle I can refuel before dropping it back off at the airport in about 5 minutes. It's just not practical to recharge my EV after driving 1.5 hours to catch my flight.

The only other noteworthy experience was making an adjustment in a parking space and having 2 or 3 alarms going off concurrently without any indication of what they meant. (Excluding the proximity sensor, if memory serves.)

rgovostes··on Why can't we screenshot frames from DRM-protected video on Apple devices?
Apple’s GIF search feature in Messages (#images, like Giphy) is almost entirely content from TV shows and movies. It seems hypocritical for Apple to promote this as a way to express yourself, while prohibiting users from making such content themselves on Apple devices.
rgovostes··on GSA Eliminates 18F
The original formula for 18F was to hire elite tech workers coming from highly paid corporate jobs to do term-limited stints in public service at lower wages.
rgovostes··on GSA Eliminates 18F
A good article from (2015) about the formation of 18F is “Inside Obama’s Stealth Startup”, https://www.fastcompany.com/3046756/obama-and-his-geeks.

I can’t access an archived version at the moment but if someone finds a link, it is an insightful read.

You can really tell they abandoned it by the lack of references to Copilot on the website.

rgovostes··on I found a backdoor into my bed
Do you still have any? I've always wanted to acquire a Kerbango (https://en.wikipedia.org/wiki/Kerbango) for my collection. I helped dismantle the backend server that continued running in iTunes data centers, powering the Internet radio feature, long after the hardware was dead.
