bendykstra··on V2 rockets on London and surrounding counties
The V2 had a guidance computer. Early rockets were purely inertial while some later rockets also rode radio beams to their targets.
bendykstra··on Meet Model X
Fans, which force air through the filters into the cabin.
bendykstra··on Beyond ad blocking – the biggest boycott in human history
I'm not arguing one way or the other as to the morality of these situations, but I don't think that they are analogous. Each of the following should be considered separately:

1. The transfer of money from the advertiser to the ad venue

2. The viewing of the ad by the consumer

3. The effectiveness of the ad campaign as perceived by the advertiser

In the case of the bus, the most important consideration for the bus company, whether it was paid for the ad, is unaffected by whether or not you choose to look. Also, the advertiser knows beforehand that it is only paying for the probability that a passenger will sit near their ad. The fact that someone did not diligently view all the ads will not change their estimation of the ad campaign's value, since it is already factored in.

In the case of online ad blocking, all three are affected to the maximum degree. You have no chance to view the ad, the effectiveness of the blocked ad is known by the advertiser to be zero and the site is not paid.

bendykstra··on Forcing suspects to reveal phone passwords is unconstitutional, court says
After Riley v California (2014), a warrant is required before the search of a mobile device. Therefore, in a scenario where you are asked to unlock your device, the only question is whether you are required to cooperate by giving your password or offering your finger. In the case of a password, the answer appears to be no, due to the privilege against self-incrimination. In the case of fingerprints, there is no such right. You are merely identifying yourself to the phone and your identity cannot be construed as incriminating testimony.

bendykstra··on Show HN: Hacker News Simulator
My favorite is

> Show HN: nnmm – A feed of your print or paper books

Isn't this just a pile of books?

bendykstra··on Pluto ‘Wows’ in Spectacular New Backlit Panorama
New Horizons team member John Spencer answered that question on the Unmanned Spaceflight forum:

Yes, this was a single channel image (we wouldn't have held out on you if we'd had color!). Several of our closest MVIC images were b/w rather than color, because of limited time near closest approach- we can take B/W images faster than color ones, and they allow higher-res LORRI riders. We still don't know what color the haze is, though we'll have lower-resolution high-phase color images soon, which will answer that question.

bendykstra··on I love the Victorian era. So I decided to live in it
If you like this, check out the BBC's excellent series, Victorian Farm. In the show, a historian and two archaeologists live and work on a farm for a year, using only tools and techniques of the Victorian era. Experts in period crafts and trades visit the farm to demonstrate tasks like building barrels or creating lime mortar to use in the building of stone walls. Here is a farrier creating a horseshoe in minutes from a plain metal bar: https://youtu.be/-x1hP8zisUI

Although the farm is the focus of the show, a good amount of time is given to domestic labor. I used to grumble when I had to do laundry, but now when trudging down to the basement, I can only think about how much of my day has been freed up by the washing machine.

bendykstra··on The Pixel Factory

Wow, yeah. I'm using an old laptop with Ubuntu. Firefox ground to a halt, crashed and then my computer spontaneously rebooted.

bendykstra··on The Noise Around You Could Strengthen Your Passwords
If a slightly different sound resulted in an entirely different signature, the system would be useless for comparing recordings of ambient noise, which will never be identical. You've taken the analogy with hashing too far.
bendykstra··on Tesla unveils new car-charging robo-snake
I bet if you exposed another mammal like a monkey or a cat to that recharging tentacle, it would be frightened by it too. We are wired to be afraid of snakes and snaky things. It's one of the most common phobias. Sci-fi horror merely tapped into that fear.
bendykstra··on Fiat Chrysler recalls 1.4M cars after Jeep hack
I think that disabling the entertainment center's access to the internet would be the responsible thing to do. Given Toyota's recent $1.2B settlement over the unintended acceleration defect, leaving this door open to hackers could be very costly for Chrysler.
bendykstra··on Bitcoin Trends in the First Half of 2015
Those events seem outside the scope of an article that is about multi-year trends.
bendykstra··on Go GC: Solving the Latency Problem in Go 1.5
It could still be a case of one person's bloat being another's feature. Though for a website website, the other people could be advertisers, people who develop the site and people who publish content to it. There was a Mozilla report not too long ago that found that just disabling tracking (not ads) reduced page load times by almost half.
bendykstra··on What a 4am haircut taught me about hackathons
You could probably get an idea of how inflated that requirement is by looking at what percentage of the 1,500 hours is spent on issues relating to safety and hair cutting. Browsing the syllabi of barber schools, I see subjects like career networking, public speaking and small business management.

You could also compare states. In New York, the requirement is set by the school and I found one school that requires 288 hours.

bendykstra··on Simple 4-bit/1 Hz virtual computer for learning purposes
One address is used for memory-mapped I/O. (Writes go to the printer. Reading from this address produces a random value.)
bendykstra··on We scraped the World Bank's website
Hi, one of the authors here. First, though I worked on the paper, I am not employed by CGD, so these comments are my own.

The main reason for using the non-headless Firefox WebDriver was that we wanted the script to access the site just like a human user. This made it easy to explain to non-technical people exactly how we had gotten the data. We didn't want to do anything that could be seen as circumventing the interface that the World Bank had created for that purpose.

Up to a point, performance was not a concern. In fact, as slow as Selenium is, we still artificially limited the speed of the script by waiting three seconds between each set of queries. However, when it came to selecting options, it could take Selenium tens of seconds, so that was done with js.
