rtb··on Performance comparison: counting words in Python, Go, C++, C, Awk, Forth, Rust
Thanks! I think he should make that a lot clearer in the "results" table.
rtb··on Performance comparison: counting words in Python, Go, C++, C, Awk, Forth, Rust
What are the "grep" and "wc" lines doing in the results? I can't find them in his git repos.

Does he have a solution for the problem using grep, or is he just including "grep x <input" as a reference point for how fast you can read a file?

rtb··on Show HN: PSX Party – Online Multiplayer Playstation 1 Emulator Using WebRTC
Amazing. Needs multitap support for more than two players!
rtb··on My million dollar domain hobby
No mention of the ethics of this, except in a single dismissive comment?

He is deliberately land-grabbing domain names in the hope that he gets in the way of legitimate users enough that they pay him off? Scummy.

People try to distinguish between domain squatting and "domaining" by saying that the former is "bad faith" but the latter is not, but I don't really see any difference.

I hope that ICANN release enough new TLDs that this problem just goes away by dilution and the "domainers" lose all the money they "invested" in this scummy practice.

rtb··on How active noise cancellation for automotive works
> The pressure waves from both the unwanted exterior noise and manufactured anti-noise reach occupants’ eardrums at exactly the same time and cancel each other out.

What happens if your ears are not exactly where the system thinks they should be? If you are taller or shorter than they expect? If you are not sitting in the drivers seat? If you lean over?

My guess would be that the system makes things worse more often than it makes things better, if it relies on your ears being in the correct position.

The wavelength of middle C is something like 2 feet, so if your ears move by 1 foot will you be getting double noise, rather than zero noise?

rtb··on Surveillance on UK council websites [pdf]
The alternative is to not show ads.

Yes, Google Analytics has many of the same problems. The alternative to that is to analyze the server logs or to simply not track your users' behaviour in detail.

rtb··on Surveillance on UK council websites [pdf]
I think they understand it fine. As you say, the website is using Google's ad server. So it is sending detailed identifying info about each user to Google.

Just because that has become normal for "the online ad ecosystem" over the past few years doesn't mean that it should be acceptable or that we cannot try to stop it.

rtb··on Congrats! Web scraping is legal! (US precedent)
US law has a very similar approach. See e.g. https://www.bitlaw.com/copyright/database.html

But I don't think that's relevant here, as a) this isn't a copyright case and b) HiQ are not attempting to recreate the entire "compilation" of LinkedIn

rtb··on Why So Many Londoners Live in 'Two-Up, Two-Down' Housing
Yes, coal heating was banned around that time. https://en.wikipedia.org/wiki/Clean_Air_Act_1956

Great list.

rtb··on Ask HN: Is there a platform for sharing ideas that people want to “give away”?
A quick search for "send letter online" shows there are at least 2 or 3 companies that offer this currently.
rtb··on A copy of your property deed costs $3 – this SoCal firm will do it for $89
Surely this is just fraud, i.e. obtaining money by deception? Do they really need a new law to ban this, or do they need to enforce the existing laws better?
rtb··on My Sudden Trip to Hell
I agree. I find it heartbreaking that the brightest minds of our generation are working on better ways to get spam into people's mailboxes. He more or less worked himself to death just to "enable our customers to deliver a highly responsive, on-demand experience with their marketing and their content."

Surely the world would be better off without further optimising targeted spam.

rtb··on My Sudden Trip to Hell
No-one is claiming that stress synthesizes bacteria, that is a laughable strawman.

We are surrounded by bacteria at all times. If stress were to weaken your immune system, then you might be more easily infected by them. This seems completely plausible to me (likely, even). It is not a great leap to describe this link as stress "causing" the infection, even if it might be better to describe it more precisely. Perhaps "stress meant he couldn't fight off the infection as he normally would have"?

rtb··on Madoff whistleblower Harry Markopolos calls GE a ‘bigger fraud than Enron’
There are two economists – one young and one old – walking down the street together.

The young economist looks down and sees a $20 bill on the street and says, “Hey, look a twenty-dollar bill!”

Without even looking, his older and wiser colleague replies, “Nonsense. If there had been a twenty-dollar lying on the street, someone would have already picked it up by now.”

rtb··on Preparing for Prison (2016)
The author doesn't mention endemic rape in US prisons because he is writing about UK prisons.

All Americans should be ashamed of the state of their prison system.

rtb··on Lawsuits Aim Billions in Fines at Equifax and Ad-Targeting Companies

  "Brian Vecci, technical evangelist at Varonis, 
  elaborated on what he saw as the downside of the
  zeal to crack down on data brokers.
  
  “Entire business models could be declared illegal
  and have to be scrapped if these complaints are 
  valid, and that might be a bad thing for 
  consumers,"
Sounds great to me. He has completely failed to show any real downside.

Because people don't think they're being watched.

... so it is deceptive to watch them.

rtb··on What's wrong with the default build tool for Scala
Maven is no longer maintained, and has many long-standing bugs that may never get fixed.
rtb··on A Beginner´s Guide to Getting Things Done
It is discussed in the book. You should just read the book if you want to consider this seriously.

If you're just looking for a summary: there is very little point writing things in a list if you don't read the list, obvs.

The key to GTD is that if you actually do write everything in lists and calendars, then you are freed from having to remember things. If you can reach that inflection point, then it frees up a lot of mental capacity and is glorious. Remembering things is surprisingly mentally draining, as it basically consists of thinking about them every now and then.

Read the book.

rtb··on Show HN: React PWA – A scalable Progressive Web Application foundation
I got a plain 504 the first time I tried.

I refreshed, and got a Cloudflare page with a banner at the top saying "This page (https://www.reactpwa.com/) is currently offline. However, because the site uses Cloudflare's Always Online™ technology you can continue to surf a snapshot of the site." The bottom of that page where the "snapshot of the site" presumably should be is a differently branded 502 error page.

rtb··on Accessibility at Trivago
> Would those be thrown out if the A/B test was a fail?

It sounds like it, yes.

> there are legal, ethical and moral obligations.

From the evidence in this article, Trivago don't give a shit (or didn't)

rtb··on Equifax C.E.O. Richard Smith Retires After Huge Data Breach
Because you can't prove damages. If you suffer loss that you can directly link back to Equifax, and you manage to get your day in court, you'd get damages just like if you had a faulty steering wheel.

The problem for the law is that things are much more indirect in this case.
