garkin··on Bitcoin hits $1T in market value
Being middle class is not a crime and never was.
garkin··on Microsoft Edge is now the second most-used desktop browser
I just tested it. They use built-in Microsoft Sam as TTS (at least in Windows), old and awfull.

TTS in the Edge is pretty close to the bleeding edge. It's good. Both English and Russian. And Edge is still a gorgeus Chromium without recent time UI degradations and without ad- and privacy- blocker intolerant management.

Personally i have a prejudice against Firefox for subjectively poor and ugly UI and old scars from their rendering issues.

garkin··on Microsoft Edge is now the second most-used desktop browser
I personally use Edge almost daily for their awesome in-browser TTS and reading-mode feature. I inspire you to try it.

For general purpose Google account integration convinience grip is yet overweights their constant effort to ruin UI and extensions. Also Edge App Store still lacks uMatrix, but already has uBlock Origin.

Energy is not the only thing you should care about freight and human logistics. Logistical resources of cities are scarce and it already badly affects labor market there.
garkin··on Dark matter nightmare: What if we are just using the wrong equations?
Dark matter sounds super intuitive as for me.

Let's assume we observe a system of planets and we have a good theory to describe its behavior. Then with better tools and more observation we found an orbit deviation. Patch it by assuming additional yet unobserved planet? Or patch it with much more sophisticated mathematics?

garkin··on A Look at the AMD Zen 2 Core
Here is a fresh Zen1 timings comparison from Reddit[1].

Most increase is between 3200cl14 vs 3200cl12. 12%. Difference between this two is almost purely a Latency.

Then compare 3200cl12 and 3600cl14 - 3%, marginally no increase. Almost no difference in latency, only throughput and IF.

Past 3200 RAM throughput and inter-core-communication (IF) has very little influence for Zen1 gaming. For Zen2 this scenario would differ in some ways but not too much.

2400 vs 3000 vs 3200 MHz RAM | Ryzen 2nd gen: https://youtu.be/TjMq-Nv6Mq8

It affects general tasks too, but with much less magnitude than gaming, because games are concerned with frame times and overall latency the most.

garkin··on A Look at the AMD Zen 2 Core
I will distill your post to: most user builds are bad balanced to begin with and they wont see a difference and would had a better price / more cores. Valid point, i agree with it. Still could be argued about a need for a better memory for Ryzen. This equalizes total build cost and you need to be informed about this platform trait beforehand, which will results in even worse average build balance. Imagine prebuilt PCs from wallmart with 2400 leftovers.

But my point is more about advanced user builds and press benchmarks.

[0] - 2400 cl16. It's much worse than 3600 cl16, used in referenced Ryzen 3000 test. It would be interesting to see how Ryzen would perform with it. May be zen2 comparison with 2400 vs 3400 (3600 is very rarely achievable there as IMC trait of the platform) would be a good illustration.

[1] - 3200 C16. But it performs way bellow expectations. Modern Intel chip should have ~55ns with it. With 3600 cl16 intel will have ~40ns.

garkin··on A Look at the AMD Zen 2 Core
Zen 2 is very good in number crunching and synthetics. But it has a problem - terrible memory latency. 70ns with 3600cl16. (https://www.userbenchmark.com/UserRun/18168279) It distills to a not-so-good gaming frame times. It's 64mb L3 cache (https://en.wikichip.org/wiki/amd/ryzen_9/3900x) helps only partially.

Few games will suffer greatly from it, but there are several titles with RAM bottlenecks, like PUBG and FarCry.

Anyway, AMD has a much better price/performance offer than Intel. For general puprose Intel is totaly anihilated, but for the games they are still more than competitive.

garkin··on Why Medium Sucks
My only problem with Medium are rehosted "personal blog" junk domains. Otherwise uBlock would work without any additional effort.
garkin··on Google Just Gave 2B Chrome Users a Reason to Switch to Firefox
It's more like "25% and counting". It was ~3% 10 years ago. Tendency is pretty obvious and omnious for Google and like.
garkin··on Ask HN: Do you keep a personal knowledge repository?
https://workflowy.com/ This simple yet robust app totaly ruined mind maps for me.
garkin··on NPM staff fired after trying to unionize – complaints
"Potential threat" trading in modern world is ridiculous. Why doesn't it smell ultra iatrogenic for anyone?
garkin··on Available on Google Cloud: Intel Optane DC Persistent Memory
It uses Intel Optane. It's basically super fast SSD used as RAM.
garkin··on TSMC: First 7nm EUV Chips Taped Out, 5nm Risk Production in Q2 2019
There realy should be some kind of ISO about node naming. I guarantee this "5nm" would be as much missleading as their "7nm". Only thing that matters is wafer price, yield, transistor count and TDP.
garkin··on Try OCaml
I tried ReasonML an year ago.

It was __very__ amusing to play with Variants, Pattern Matching and Units. If programm compiles - it almost always just works. It's an indispensable tool to play around and get more ideas how to write a better programs.

And it was disastrous in __everything__ else. Installation and compiler bugs. Terrible tooling. Terrible code packaging. Terrible Javascript interop. Painfully archaic syntax. Sometimes extremely esoteric compiler errors.

After a week i thrown out all the code and rewritten it using Typescript. Won't ever use new languages on projects with deadlines, no matter how sweet evangilists talks are.

Why did you drop OCaml?
garkin··on Building multiplayer games with Socket.io and HTML5 Canvas
It's not for client. It's for server and bandwidth.
garkin··on Preact, React alternative without weird Patents License
I watched both a while ago, things could have changed.

Inferno was positioned back then as some kind of a ressearch thing not suited for production.

Preact pros was:

- very small size (it's near 5kb Non-Gzipped without compatibility layer), perfect for lightweb mobile apps (Inferno was like 60kb, React 250kb)

- has less gimmicks for porting from React and an optional compatibility layer to enable some of low-level React libs and components

Preact has no synthetic event system wrapping, if you heavily relly on it then things could be rough.
