leecb··on Making regular GPS ultra-precise
> The Quasi-Zenith Satellite System (QZSS) (Japanese: 準天頂衛星システム, Hepburn: juntenchō eisei shisutemu), also known as Michibiki (みちびき, "guidance"), is a regional navigation satellite system (RNSS) and a satellite-based augmentation system (SBAS) developed by the Japanese government to enhance the United States-operated Global Positioning System (GPS) in the Asia-Oceania regions, with a focus on Japan.

leecb··on Alleged M4 MacBook Pro unboxing video
I wonder how much of this increase is solely enabled by TSMC process upgrades, either through higher clock speeds or increased number of transistors per core? It's kind of interesting that every iteration of the M series has corresponded to a change of TSMC process.

M1: 16 billion transistors at 3.2 GHz on TSMC N5

M2: 20 billion transistors at 3.7 GHz on TSMC N5P

M3: 25 billion transistors at 4.05 GHz on TSMC N3B

M4: 28 billion transistors at ?? GHz on TSMC N3E

leecb··on Telecom Industry Is Mad Because the FCC Might Examine High Broadband Prices
AT&T ran fiber to my house (and everybody else on my street). 15 months later, the highest speed option we have is still 50/10 Mbps DSL from AT&T.

I wonder why they put it in if they aren't going to bother offering service with it?

leecb··on New Loongson chip matches Intel's 14600K in IPC tests, overclocked to 3 GHz
What operating system would be run by PCs using this chip? Are there existing operating systems that support LoongArch?
leecb··on Braid, Anniversary Edition trailer [video]
Very excited that this unique game continues. It's too bad they aren't supporting the Mac, like the old game did.
leecb··on Server-side rendering is a better choice for many applications (2020)
> taking over 500ms and a complete page reload

For me this is 45ms to transfer the 2 kB (compressed) of HTML; the whole process takes under 60ms total, which is pretty darn close to "instantaneous" for the "complete page reload."

EDIT: I'm in Texas, so most of this time is probably just round trip time to the west coast.

leecb··on Tesla repossessed my car due to an extreme oversight on their end
This was not paid with a check, but a cashier's check, and so the money would have already been gone from their account:

From the post:

> The car was paid for with a combination of card and CASHIER’S check. Cashiers check means the amount of money is withdrawn from the bank when it’s ISSUED not cashed. so no, we did not notice extra money sitting in our account because it had already been withdrawn.

leecb··on Apple dives into display-making to cut reliance on Samsung
> MicroLEDs are still just LCDs with a better backlight but LCD Tech has evolved quite a lot and pixel refresh time (< 3-4ms) is not much of a problem anymore.

You're thinking of MiniLED, which is just better LEDs behind an LCD.

MicroLED is a whole different ball game, with no LCD at all. It's just red, green, blue LEDs, one for each pixel.

leecb··on CSS Paged Media Module Level 3
Weasyprint is an excellent tool for converting HTML to PDF. It has supported CSS Paged Media Module for a while; this has been very useful for making printable PDFs from web pages.

Weasyprint seems to be one of the few HTML->PDF engines out there that doesn't depend on a browser engine. It's impressive just how much works (HTML, CSS, SVG, etc), given that this is a relatively simple project compared to a full-featured browser. Performance isn't bad, considering it is implemented in Python.

The improvements seem to be in which thread WebRTC does work: moving more work to workers and off the main thread.

The release notes for alpha builds (e.g. [1]) link to this bug [2] "[meta] Update libwebrtc to new stable branch 2H2020", which as a number of comments about WebRTC using the main thread as its worker thread.

leecb··on Apple sues NSO Group to curb the abuse of state-sponsored spyware
> those inane licenses no one reads, do we really want them to legally binding?

What all would be possible if software EULAs weren't legally binding?

One thing that EULAs typically do is reduce liability for the company producing the software. Imagine if Google/Apple were liable for damages from all the miscommunications caused by autocorrect?

leecb··on Plunge in lithium-ion battery costs
> The element is cobalt, Kobalt is a brand of tools

Kobalt is the name of the element in German; @jillesvangurp's profile says he is based in Berlin, perhaps he also speaks German. (German also capitalizes nouns.)

leecb··on Why thieves love to steal catalytic converters
Tesla has demonstrated that their batteries can be removed and replaced in a matter of a minute or two, given the right equipment.

https://www.tesla.com/videos/battery-swap-event

Since the batteries cost an order of magnitude more than a catalytic converter, this could justify criminals developing more sophisticated equipment to pull it off.

> accumulated rubber from those landings

Rubber accumulation on runways is a normal and expected situation. Part of runway maintenance at airports serving larger aircraft includes regular removal of the rubber using high pressure water or chemicals.

leecb··on Show HN: I developed a native macOS Hacker News client
Very happy to see a "mac-assed" app!

My only complaint so far is that I can only see about 12 items in the app on one screen, vs the whole front page in a browser. Adds a lot more scrolling.

leecb··on PG&E will bury 10k miles of power lines so they don't spark wildfires
> My vision of the future has all power lines buried.

Singapore already has already achieved this. It's actually quite pleasant to not have any overhead lines.

They are currently replacing the main electricity distribution cables that run under roads, and replacing them with a system that runs in tunnels 60m underground. This depth is necessary to avoid other systems like the subway(MRT) that run at shallower depths. https://www.todayonline.com/singapore/deepest-tunnels-spore-...

leecb··on Hello, HPy
Related but separate from the subinterpreters PEP, there is interest in moving from a global interpreter lock to one lock per subinterpreter. This would need to be in place before running Python interpreters truly in parallel within one process. There’s a great summary here: https://lwn.net/Articles/820424/
leecb··on Apple’s Independent Repair Provider program expands globally
I've personally had an iPhone 8 purchased in Thailand replaced under warranty in Sydney. I've had US-purchased Macbook Pros serviced in many other countries, including batteries (Canada, Thailand), mainboards (Germany, Singapore), top cases (butterfly keyboard in Thailand and Germany) and screens (Texas, Thailand). Certainly seems global to me, though countries without Apple stores are most definitely second class participants in Apple's repair network.
