xentronium··on Everything Is Booming Except for Wages
1. CPI is a wrong deflator to use when comparing to GDP growth

2. Wages != Compensation

xentronium··on Ask HN: Were you happy moving your API from REST to GraphQL?
Our front end engineers were extremely happy. Me personally, as a backend engineer, not as much, but it isn't too bad.

There are some quirks (error handling), performance issues (e.g. fixing n+1 queries) and DOS concerns, but again, it isn't all that bad.

(we're using rails/graphql-ruby on backend | react/relay on frontend)

xentronium··on Regarding the Em Dash
Depends on typography traditions. In Russian, em-dash in the middle of a sentence is always typeset with short spaces. We also rarely use en-dashes (I think there are maybe two cases when it is allowed: in date ranges like 1940–1945 and as a bullet point in lists).
xentronium··on F.C.C. Repeals Net Neutrality Rules
> In what bizarro world would anyone actually want ISPs competing for the last mile

You can easily have up to 1 gbit symmetric internet connection in Russia for $10 because of that competition.

It's not rocket science, guys, US ISPs suck because your regulation killed all the competitors, and your solution is what, more regulation?

Are you confusing tw with twhr/y?
xentronium··on How I Used Twilio, Python and Google to Automate My Wedding
Well, not exactly an app, but some forums dedicated to reviews for courtesans are quite old.

There is a setting for menu being always on.
xentronium··on What CSS minifiers also leave behind
Man, just post a link to CV like you're advised and let good things happen to you. If they don't, you lose nothing, but if they do, you got something out of your effort.
xentronium··on Chekhov: “Cultured people must, in my opinion, satisfy the following conditions”
Chekhov had this very weird and dry sense of humor. Some jokes would certainly look like insults to a random observer.

In this case, though, I believe he was actually frank, if blunt, but well meaning (his brother had issues with alcohol).

xentronium··on Russia Blocks Porn Site Brazzers for 'Damaging Human Psyche'
Russian laws effectively prohibit all kinds of internet pornography. More precisely, they restrict "unlawful distribution of pornography", but never define any "lawful" way to do so.

---

That said, if it weren't pornography, small rant about our judicial system:

Any judge in any city pop 50000 can issue a country-wide block for any site. Often these resolutions are too far reaching, sometimes they order to block root page (/) instead of specific page (/foo/bar), rendering whole sites unavailable. Sometimes they ban ip addresses of aws services, disrupting half the internet.

Another important thing about these hearings is that there is often no defendant. They might call in the site hoster, but hosters are never interested in defending their customers so they simply ignore the subpoena. Site owner would often discover their site was blocked after the fact.

Finally, in many cases judges don't even bother writing their own verdict. Instead they copy-paste whatever public attorney cooked up, including all the factual and orthographic errors, and sign it.

https://medium.com/@aalien/law-limits-8d733178e158 this is a very insightful post (alas, only available in Russian) from @aalien, founder of lurkmore.ru, which is arguably the most often banned site in Russia, about how this horrible system functions (or rather, malfunctions). I found this excerpt especially hilarious:

«Full list of Roskomnadzor-banned pages is available on our site. Unfortunately, that page is also banned by Roskomnadzor, because it contains "textual information about committing suicide". It's in the quoted Roskomnadzor letter, of course»

xentronium··on Getting Started with Webpack 2
> Now, the JS community seems to be thinking more about stability and backwards compatibility. That's very welcome, at least from the perspective of this grumpy server-side developer.

That's exactly why the blog post suggests using yarn instead of npm, isn't it?

xentronium··on ESPN Loses 621,000 Subscribers; Worst Month in Company History
> I don't think any sport-themed games are played professionally though.

FIFA is somewhat popular.

xentronium··on Vine will be discontinuing the mobile app
coub.com? I thought it was quite popular, but apparently that's only in Russia.

Blood, anyone? I think Blood is the single scariest game I played as a teenager.
xentronium··on Verifying Wikileaks DKIM-Signatures
I remember having issues verifying emails with attachments last time I've used dkimverify.
xentronium··on Civ VI 'AI Battle Royale' on Twitch
Yeah, civ 5 ai sucks, and don't even get me started about combat (builds all the wrong units and can't properly control the armies it has). I blame 1-unit-per-tile change.

It's a shame, especially since in multiplayer this game is amazing (except for, cough, networking code, cough).

xentronium··on The GitHub GraphQL API
In rails/graphql combo it's resolved the same way you usually resolve n+1 queries: you make 1 request per type of edge (i.e. one request for posts, one request for authors, on request for comments)

xentronium··on Ruby on Rails Tutorial
I kind of agree with GP sentiment for two reasons:

1. Nowadays I mostly advice newcomers to start with sinatra instead of rails, because rails keeps growing in scope and the surface to cover is huge

2. Lots of things rails does might seem magical if you don't know ruby

Don't get me wrong, rails is still bread and butter of myself and other rubyists, but for a newcomer to start with rails is a somewhat strange/scary thing to do.

xentronium··on New Features in Ruby 2.4
It's also reverse.
xentronium··on How to be a wizard programmer
I think you're right when it comes to basic questions (like "how to do XXX in rails"). However, in my practice, 90% of the obstacles are not concerned with how to do something in the framework/language of choice, but rather "how do we do XXX in our code?" (state machines, search, billing, reporting, etc). These questions can be answered by digging into code and understanding the logic, however, it's better if someone senior explains how and why they do things the way they do, clarifies rationale.

You're missing the central point of default rails stack.

xentronium··on How to win the coding interview
> If by "well documented" you mean "lots of people have whinged about it at great length", then I guess you're right. It's also a "tried and tested" method, too, so it's got that going for it.

You are wrong. Just because it's most used currently doesn't mean it's better. And it is actually well documented.
