MrVitaliy··on macOS 27 Golden Gate – Review
Apple seems to be doing a lot better job at integrating LLMs into OS, than Microsoft.
MrVitaliy··on Improving Heuristics for A* Pathfinding
One of my fav LLM tests is asking it to implement A* algorithm, in X language, in a single file, output 80x40 char map with random obstacles and show the path. Ask it to build UI or change path heuristiscs, etc.

It's such a quick prompt but can quickly signal how useful the model is in that language or framework, how much you have to constraint output with specs and tests.

MrVitaliy··on Nvidia DGX Spark as a daily driver
I do appreciate how Nvidia tries to say close to vanilla with Linux and Android (nvidia shield). Instead of trying to build a shitty moat like Samsung with all their garbage software.

If nvidia ever releases Android smartphone, I'd probably stand in line to get one.

MrVitaliy··on AMD Ryzen 7 7700X3D Review: 3D V-Cache Gaming Performance for Less
What people? Very few top games on Steam require kernel-level anti-cheat -- https://steamdb.info/charts/
MrVitaliy··on Linux on Older Hardware: The Complete Revival Guide
I RDP (Remmina) into a beefy VM with all the bells and whistles running FreeRDP service and do heavy web browsing there. Its also more secure if your old laptop doesn't get the latest updates.
MrVitaliy··on Wolfenstein 3D for Gameboy Color on custom cartridge (2016)
Really hope this makes it to something like Modretro/Chromatic games collection. The box art looks fantastic, love seeing resurgance of Gameboy color.
MrVitaliy··on Scores decline again for 13-year-old students in reading and mathematics
So sorry, I'm from Califurnia
MrVitaliy··on Scores decline again for 13-year-old students in reading and mathematics
States should pay more attention to Mississippi on how they were able to revamp education in under a decade.

MrVitaliy··on Xiaomi launches next-gen SU7 with 902 km range and Lidar, still undercuts Tesla
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.
MrVitaliy··on It Took Me 30 Years to Solve This VFX Problem – Green Screen Problem [video]
Anyone tried using lidar and just cut/measure distance to the object?
MrVitaliy··on Converting a $3.88 analog clock from Walmart into a ESP8266-based Wi-Fi clock
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.
MrVitaliy··on BYD Sells 4.6M Vehicles in 2025, Meets Revised Sales Goal
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?

MrVitaliy··on RAM is so expensive, Samsung won't even sell it to Samsung
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.
MrVitaliy··on KDE is now my favorite desktop
KDE is excellent, but these days all you really need is a nice terminal and a browser.
MrVitaliy··on Dumb to managed switch conversion (2010)
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.

MrVitaliy··on GM, LG to upgrade Tennessee plant to make low-cost EV batteries
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.
MrVitaliy··on IDF officers ordered to fire at unarmed crowds near Gaza food distribution sites
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··on The pigeon whistle: A defining sound of old Beijing (2019)
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··on Surnames from nicknames nobody has any more
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.
MrVitaliy··on The electric shock behind Europe's stuttering EV future
Not soon, this would requires sophistication in software and software development. US has the crown on this for now and near future at least.
MrVitaliy··on Starting today, YouTube is almost unusable on Firefox
Just have two browsers. Use Chrome for only youtube and google apps. And Firefox for rest of web use.
MrVitaliy··on Home Lab Beginners guide
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.
MrVitaliy··on Anime is a $25B industry that pays its animators pennies
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?
MrVitaliy··on Relearning math as an adult
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··on Tesla shares 48V architecture with other automakers
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.

MrVitaliy··on Israeli Researchers Produce Green Hydrogen with 90% Efficiency
I'm hopeful for hydrogen use in aviation. Either that or some ridiculous breakthrough in battery tech, and the latter seems less likely than former.
MrVitaliy··on More Than 40% of Japanese Women May Never Have Children
What's interesting to me is how Japan still has higher birthrate than Taiwan and Korea, and some say than China.
MrVitaliy··on Toyota has been developing a solid-state battery for EVs with a range of 745mi
