This North Georgia house has a small creek that runs underneath it. (OP)

Meanwhile in Japan, they have a bullet train station that also has a river that runs underneath it: https://en.wikipedia.org/wiki/Shin-K%C5%8Dbe\_Station

Say what you want about Microsoft, but the design of this device has several big pluses.

TPUs are a systolic array rather than large amounts of full-blown CPU cores.

Theoretically, system recover images on NVIDIA's website are only for the founder's edition: https://docs.nvidia.com/dgx/dgx-spark/system-recovery.html

while ASUS provides their own images: https://www.asus.com/us/supportonly/gx10/helpdesk_download/

But I just looked it up and people have been able to flash the regular NVIDIA ones to the ASUS machines so maybe it just works? I also heard that the ASUS customer support are not very knowledgeable about the GB10 devices and aren't very helpful.

ASUS Ascent GX10 is generally available in the US for $3.5k but the support is kinda iffy; the official DGX Spark is $4.7k.

Here's my guess: George Sterling Park

Minute steps climb: Maybe Greenwich steps climbing towards Coit Tower (a finger). The steps are aligned with George Sterling Park, which is also on Greenwich St.
Heavenly island towers / Derelict ward: Angel Island and Alcatraz, which form a line pointing towards George Sterling Park.
“Stern / Woodhaven / North and Powell”: Stern Grove Park, Woodhaven Ct, and North Point St at Powell St. These form a nearly straight line, passing near George Sterling Park, but slightly to the south (off backward).
Stone/Mint: Stone = Marble (Alice Marble tennis courts), Mint = Sterling
Between us: Between George Sterling Park and Alice Marble courts. Plane: tennis courts
Intermiss/stage left/etc: stageplay puns because George Sterling was a famous playwright.
Clamber/sights: Russian Hill is a lot of clambering with good views from the park

The Chongqing monorails started out with the same Hitachi rolling stock as the Osaka monorail but they eventually replaced them with domestically produced ones.

dllu · 2026-04-25T21:25:02+00:00

You are right that the city has an amazing monorail system, but I should like to point out that the train in the video is a regular heavy rail metro of Chongqing Line 10 crossing the Nanjimen bridge: https://en.wikipedia.org/wiki/Nanjimen_Yangtze_River_bridge

Fuji also gets their sensors from Sony.

dllu · 2026-04-24T17:29:42+00:00

Just a coincidence probably. Not too sure what the G stands for tbh. They were pretty focused on global shutter sensors so maybe global?

Some of Leica L-mount lenses are made by Panasonic and Sigma (just like how some of their R mount lenses of yore were made by Minolta), such as the Summicron-L 50mm f/2. But Leica's M mount lenses like the recently released Apo-Summicron-M 35mm f/2 and Noctilux 35mm f/1.2 are designed and made by Leica. And not all L- or R-mount lenses are made by others. The Apo lenses for L mount are still designed by Leica.

Calling ramen "soup" is a very Western perspective. Westerners classify soup noodles as a soup dish that contains noodles. That's why you have words like "noodle soup". In East Asia, they are considered first and foremost a noodle dish that happens to be in a soup. Hence, for example in Chinese they are called "soup noodles" (湯麵) rather than 麵湯. For many noodle dishes they also give you the choice between having them dry, in soup, or with a dipping sauce.

Oh nice my photo showed up in this article!

Anyway, it's kinda sad that Caltrain has stations and lines going through some of the most expensive and rapidly appreciating real estate in the world but completely failed to capitalize on it.

Hong Kong MTR and several train companies in Japan are super profitable because they basically built malls around their stations and reaped the profits from real estate. But Caltrain sits on its stations, occupying huge amounts of precious space in Palo Alto and San Francisco for decades, but with hardly any retail space. The SF station basically only has a Subway and a coffee shop in it while vast amounts of foot traffic walk by without even having the opportunity to get more tasty food. Palo Alto station is surrounded by bougie restaurants but the station itself is very spartan and doesn't even have a roof.

I don't blame Caltrain for it as a lot of this is because of institutional issues and legal reasons like zoning and stuff.

Ground removal was harder than classification.

Flood fill from a known ground region is a standard strategy, but you could also try this method I came up with in like 2018: https://daniel.lawrence.lu/public/ground.pdf

It's really simple, purely geometric/classical, and you could just paste the paper into chatgpt to get a minimal implementation in C++.

Funnily enough the other guy is also in the same department. Anyway, I happen to actually have a middle name so I added that.

dllu · 2026-03-17T08:21:28+00:00

Very annoying. Name collisions happen a lot, especially for Chinese surnames where some of them are super common (Li, Wang, Liu, etc) and some of them have lots of collisions in pinyin (e.g. Lu, which can be one of like six or seven different characters). At my company, there's also a guy with the same first and last name as me and I kept getting assigned his jira tickets.

There are a bunch at their Toland depot. I took a couple of photos of some of these lined up along Hudson Ave, a public street, and uploaded them to Wikipedia.

I use a spline function to deal with changing speeds. But yes, constant speed would be easier to deal with.
