Really hope this makes it to something like Modretro/Chromatic games collection. The box art looks fantastic, love seeing resurgance of Gameboy color.

States should pay more attention to Mississippi on how they were able to revamp education in under a decade.

Interesting that they prominently feature Lidar as an upgrade over whatever Tesla has. Sheds some light on the whole drama with lidar vs camera in self-driving.

Anyone tried using lidar and just cut/measure distance to the object?

Cute, but the original clock used to run on AA battery that needs a replacement every two years or so, and now it needs a power supply. Or some big battery recharge/replacement every few hours maybe days.

What's facinating to me is the lack of software comparison in comments. Lots of comments where people compare driving noise, material quality, price to Tesla and other brands. Sure it's important to some, but its like comparing apple vs android watch by how the leather strap feels on each device.

Anyone has experience with BYD over-the-air-updates? Do they release updates often? Are there any serious bugs like with Lucid air? How does the software compare to Tesla?

Just performance when compared to current generation hardware. Not significantly worse, but things like DDR4 ram and single thread performance show the signs of aging. Frankly for similar $$$ you can get a new hardware from beelink or equivalent.

KDE is excellent, but these days all you really need is a nice terminal and a browser.

New comment by MrVitaliy in "Dumb to managed switch conversion (2010)"

MrVitaliy — Tue, 12 Aug 2025 23:25:16 +0000

There are a ton of features that fall under 'managed' umbrella, but for most home usecases you don't really need to manage the switches often. Once you setup WiFi SSIDs with VLAN tags, you almost never have to touch the switch. I like to separate networks with VLANs.

If your WiFi doesn't have client isolation, IoT devices can still scan your network. WiFi client isolation will prevent that, having them on separate VLAN also makes sense.

Another usecase is a Guest network, when friends come over. You might not want to isolate clients there and allow devices to talk to each other, but also don't interfere with your home network.

If you work from home, depending on what you do, you might want to have 'office' VLAN. Or a 'Kids' VLAN, where internet turns off every night at 8pm.

At this point, it may be easier to QoS and give only 10% of your internet bandwidth to Guest network, and 5% to IoT device network, etc.

Also worth keeping in mind that "degradation" usually means the battery holds 80% of original charge. Basically your range shrinks from 300 miles to 240 miles. Automobile with 240 miles range is still a very useful car.

Thank you for sharing your perspective Yoav, it's refreshing to read comments from an actual observer and not an army of armchair warriors.

MrVitaliy — Wed, 14 May 2025 23:42:09 +0000

This sounds similar to the sound a hybrid Toyota makes when backing up. I wonder if in this geographic area, hybrid car awareness sounds should be something like construction banging, just to differentiate from the ambiance.

MrVitaliy — Mon, 10 Feb 2025 18:54:54 +0000

The surnames with the suffix -enko are the most known and common Ukrainian surnames. Where "en" is roughly son-of or a child-of equivalent in English, and the "ko" means a smaller, baby version. For example Kovalenko where "Koval" means blacksmith, Petrenko where Petre or Petro if from a biblical name Peter.

Surprised author didn't mention https://labgopher.com/ for finding used enterprise hardware at low cost on ebay. This hardware is cheap and typically out-of-service for enterprise, but great for home labs.

Japan has a fascinating culture. Wouldn't you say the same thing about video games? Which studio can sustain 6-7 years of active game development (The Legend of Zelda Breath of the Wild) exclusive for one console?

New comment by MrVitaliy in "Relearning math as an adult"

MrVitaliy — Fri, 19 Jan 2024 05:28:31 +0000

I think it's a weird way to learn math, and I learned it this way in school. Most of these courses just teach information memorization and recall. sin(x)^2 + cos(x)^2 = 1, etc.

I would start with something like Elementary Analysis: The Theory of Calculus, and work from there. You'll eventually arrive at the same place -- Calculus but from a much stronger mathematical foundation.

MrVitaliy — Fri, 08 Dec 2023 01:46:37 +0000

PoE over CAN bus moves more complexity from EE world into software world. While Tesla currently has best auto software, this is still a very foreign and a different way of thinking/managing for traditional auto manufacturing. This won't be just using a different set of cables, it's going to flip their engineering departments upside down.
