wizzard0··on Design your day with the knowledge of your future capacity to perform
Do you have an API? Both pushing markers and pulling predictions is interesting. I believe a lot of ppl on HN who take this seriously already have at least some contraptions where integration is valuable (instead of "fifteenth competing standard")
wizzard0··on Cloudflare for Offices
Physical security of these boxes is really interesting (e.g. as CF holds a lot of SSL certificates the profit of hacking into these boxes is likely a lot higher than looks at first glance)
wizzard0··on Xata – Database service for serverless apps
Well, congrats with the launch!

As for "too early" - well, yes. Sounds good in theory, except there's absolutely no detail from both a developer or a founder's perspective.

That is, can't provide feedback when there's nothing apart from the landing page to evaluate :/

Some preliminary API docs maybe? Those should spark a discussion pretty well imho

wizzard0··on A guide to Windows application development using w64devkit
I wonder if a similar toolkit could be assembled for the GUI apps using Zig, Nim or some other fancy new C-like languages plus a minimalistic UI wrapper.
wizzard0··on Requirements change: migrating either/or data schema
> Final design should be the same no matter what was the order of implementing requirements

-- good one!

wizzard0··on Adolescents’ rich and nuanced relationship with risky behaviour
Yep, I decided to submit under a more neutral tone because the "Sex and drugs" part felt too sensational, but the result got too opinionated. Will try better next time.

UPD: Also... isnt "when Steinberg told the adolescents that their friends were watching from an adjacent room, they took significantly more risks" an environment/culture influence? I don't mean environment like "nature", but the social one, and that includes peer pressure.

wizzard0··on Telegram Remote Code Execution Zero-Day Vulnerability
Calling it "remote code execution" is veeeery clickbait-y. By this logic, any website with download links uses "remote code execution".

Even the source article says just "zero-day".

Also, tldr: Using Unicode Right-To-Left, you can make Telegram show file name "gpj.js" as "sj.jpg". That's all.

wizzard0··on Show HN: Observable Notebooks
basically if you have a bunch of code blocks that depend on each others' results - you don't have to remember which ones to update if you changed one, it will update automatically.

especially useful with data visualization/exploration, but also helps a lot if you have a complex sequence where it's easy to get lost and forget to recompute something. there's a youtube link in the comments here which explains a lot.

wizzard0··on Multipath TCP Check
Very nice, but the website looks down. Looking forward to play more.
wizzard0··on Show HN: Strukt – a visual shell for tabular data
I'm mostly interested in rich data retrieval/query building UI, and Plot.ly seems focused more on the second part of the problem, where your datasets are already prepared.
wizzard0··on Show HN: Strukt – a visual shell for tabular data
If it really works as advertised, I'd happily purchase it right away. But I need Windows or Linux version.
wizzard0··on Milagro: Distributed Cryptosystem for Cloud Computing
There's a bounty of $100M (at the very least) for cracking 256-bit (128-bit strong) elliptic curves. It's called Bitcoin :)

So if they're broken - we'll know that very, very fast.

wizzard0··on New batteries could make phones, drones, and electric cars last twice as long
Note that having a compressed energy ready for rapid release is exactly equal to handling an explosive in your laptop :)

There are a lot of experimental batteries that have like 5x capacity of the current Li-ion ones, but melt and explode when heated or crushed, which makes them effectively useless.

This is one of the hardest problems in high-capacity batteries - to avoid "rapid unscheduled heat dissipation" and the following "rapid unscheduled disassembly".

wizzard0··on Dtrace Conf 2016 Event Videos
Can you please re-check the link? It seems to be broken, and your user profile lists only the Property Oriented Programming from 2013
wizzard0··on Xiaomi’s first laptop is a Macbook Air rival
Maybe because "many of Xiaomi products — particularly its first forays into new categories — are China-only affairs"?

Also, visual similarities do not always translate into legally-pursuable patent violations, or similar.

wizzard0··on A GitHub repo required for any Elm code
That's consistent with other approaches taken by Elm (like ports for FFI). It streamlines things, but sometimes is too restrictive.
wizzard0··on Show HN: Telegram bot with filters to read Hacker News
would be better if number of points was shown on comments button, to save one line of text on mobile devices
wizzard0··on “You pay to read research you fund. That’s ludicrous”
arXiv charges neither for reading nor for publication. And for-profit publishers have to be profitable to exist, which necessarily incurs costs on authors and readers.
wizzard0··on The 3DS Cryptosystem
Another illustration of the classic thesis "security should be built from the ground up and can't be added later". Also shows the importance of minimizing the attack surface. Would love to hear some inside stories about discussions that ultimately led to these implementation decisions.
wizzard0··on Solution to one of the “Millennium Prize Problems”
It's in russian.
wizzard0··on Akka, Haskell, Erlang, Go and .NET Core compared on 1M threads
Another .NET version arrived, 2x faster LOL
wizzard0··on Akka, Haskell, Erlang, Go and .NET Core compared on 1M threads
There's an update for Akka version, which measures 12/8/4.4 seconds on subsequent attempts, so yes, warmup is important... but somehow that seems kinda unfair for other languages too.
wizzard0··on Akka, Haskell, Erlang, Go and .NET Core compared on 1M threads
It's indeed apples vs oranges vs pies (Actors/Coroutines/Futures). Probably should make a table :)
wizzard0··on Akka, Haskell, Erlang, Go and .NET Core compared on 1M threads
Returning num instead of Promise.resolve(num) is unfair compared to .NET version ;) but I merged your PR as-is
wizzard0··on Akka, Haskell, Erlang, Go and .NET Core compared on 1M threads
There's updated Akka version which is a lot faster, btw.
wizzard0··on Akka, Haskell, Erlang, Go and .NET Core compared on 1M threads
BTW, there's a merged PR which makes Akka a lot faster; can someone measure that on OS X (MB Air or MB'2015) ?
wizzard0··on Akka, Haskell, Erlang, Go and .NET Core compared on 1M threads
You can't create 1M threads on Windows (or OS X, for that matter) because there won't be enough RAM for stack space. (also, running more threads than physical cores on CPU-bound task is pretty pointless).

Maybe you mean we should schedule something which has a complete event loop? That would be a lot more fair wrt the Akka version, but the Go version does not create any threads either.

wizzard0··on Akka, Haskell, Erlang, Go and .NET Core compared on 1M threads
Updated to use Task.Run, got only 15% perf decrease, which can be due to the delegate creation too...
wizzard0··on Akka, Haskell, Erlang, Go and .NET Core compared on 1M threads
See the updated version. Runs about 15-20% slower, which is far less than the difference between single-threaded version and task-based one. Also, it's pretty easy to see in Task manager how all the cores get loaded.
wizzard0··on Akka, Haskell, Erlang, Go and .NET Core compared on 1M threads
Haskell maybe?
