jrcii··on Stanford quantifies the privacy-stripping power of metadata
An MIT project reached the same conclusion a couple years ago http://www.independent.co.uk/life-style/gadgets-and-tech/mit...

Someone from MIT also contributed to this study in the same vein http://www.nature.com/articles/srep01376 From the abstract, "[I]n a dataset where the location of an individual is specified hourly, and with a spatial resolution equal to that given by the carrier's antennas, four spatio-temporal points are enough to uniquely identify 95% of the individuals."

jrcii··on A Small London Company That Makes Beautiful Globes
I'm happy that these are out there. I make a point to find the highest quality versions of the products I buy, the product research is somewhat of a hobby. I researched globes a couple years ago and was disappointed that globes appeared to be one of the only products I couldn't find a high quality version of. Even the best I found in construction quality were mediocre and had inaccurate maps.
jrcii··on Hidden Microphones Part of Government Surveillance Program in the Bay Area
I've become increasingly convinced that western society will accept anything so long as it's fed, housed, and safe. If that's true, as a society we have a lot of rights that we're not willing to fight for but which the government is highly intent on restricting - an equation for inevitably losing them.
jrcii··on How I fell in love with a programming language
Is that love for Clojure past tense?
jrcii··on Ask HN: Which hackers do you look up to the most?
Leslie Lamport. There are a dozen larger than life programmers out there, but reading his biography I was struck with a kind of resigned sorrow at the concrete expression of a certain ideal life that I always wanted for myself and know I'll never achieve. BS from MIT at an absurd age, math PhD, goes on to write TLA+ which is a marvel of sophistication. Turing Award.

The king kind of has to be Dennis Ritchie in my mind, I can't think of code that's more influential in general and definitely in my life than C and Unix.

I like Rich Hickey a lot, what he's done and judging from his talks his personality.

More obscure but this guy Fabrice Bellard is an animal, he puts out this insane amount of sophisticated code like, oh btw guys here's a fully working LTE stack.

jrcii··on "I know how to program, but I don't know what to program"
I have a list of project ideas 500 miles long and growing every day. I somehow feel obligated to build all of it and it gives me anxiety.
jrcii··on A Farewell to FRP
Whenever I write a bunch of code that works right away I'm highly suspicious that I'm missing something.
jrcii··on PostgreSQL Scalability: Towards Millions TPS
Slightly tangential but I'm genuinely curious, does any have a theory as to why nearly every RDBMS post on Hacker News is about Postgres and almost never MySQL or MariaDB? Considering the relative obscurity of the former it seems somewhat inexplicable.
jrcii··on Former Facebook Workers: We Routinely Suppressed Conservative News
> It's a private company's prerogative to display whatever content they wish

True, but it could be argued that users are reasonable in assuming that Facebook is a neutral or automatic platform, not manually manipulating content to achieve political goals. If that is true the ethics of misleading millions of people is at best questionable.

jrcii··on Tesla crash after flying 82 feet in the air shows importance of a crumple zone
Possibly more frequent, though neither of us have data. Driving at too high a cruising speed to have adequate reaction time is common, I've never known anyone to crash a car because they lost control during acceleration (motorcycles yes). In contrast, based on my admittedly anecdotal experiences, it's common to accelerate to avoid someone who, for instance, ran a red light or stop sign.
jrcii··on Tesla crash after flying 82 feet in the air shows importance of a crumple zone
>software based limit on the maximum acceleration

That strikes me as a bad idea. There are scenarios where you need to accelerate your car as quickly as possible to move out of the way of danger or avoid an accident.

jrcii··on MSVC CRT Sneaks in Telemetry by Default?
So much for "developers developers developers developers developers" https://www.youtube.com/watch?v=Vhh_GeBPOhs
jrcii··on VXHeaven: Source code for classic viruses
All we need now is an issue of 40Hex, 2600, and the Anarchist's Cookbook.
jrcii··on Microsoft no longer allows admins to block Windows Store access in Win10 Pro
Windows 7 was the VM, not the host.
jrcii··on Microsoft no longer allows admins to block Windows Store access in Win10 Pro
I lived through the exact same disaster. I spent HOURS on the phone trying to acquire a license for Windows 7 Enterprise, I needed it for Hyper-V. Microsoft's main number, dead-end IVR system. Tried the Microsoft Store, they routed me to the dead-end IVR system. 50 or so minutes after my initial attempt I got some person that could barely speak English from India routing me to a voicemail, a couple of times Microsoft's phone system plain hung up on me after having me on hold for 20+ minutes.

Eventually I got some person at a Microsoft Store felt bad about the whole thing and took 2 days to get a number for a rep a CDW who could get me the price. That rep didn't have the price, but took my information after a 15 minute call and promised to get it to me. When she did days later, she couldn't give me a final price because she forgot I needed a user CAL and a remote access CAL. When I went to make the final purchase, she said oh, actually we can't do it because Microsoft won't sell the Windows 7 license anymore only Windows 10.

The whole process made me feel like I was losing my mind.

jrcii··on A Basic Income Should Be the Next Big Thing
Abolish all welfare, phase out social security, and have the poor rely on private charities. If people don't want to donate to the charities that's their choice, it's their money. You're not entitled to money, food, a home, or a job -- you're entitled to nothing. You're entitled to starve in the gutter. If you want something more you have to earn it or have someone voluntarily agree to give it to you out of their own free will.
jrcii··on The Secrets of Medieval Fonts
I love RSS, but I've noticed that every time I explain the concept to a non-technical person and how they would go about adding feeds and setting up a feed reader it's perceived as a complicated non-starter. I could attribute that to my own failure to explain it, but normally I'm pretty good at making technical things simple for laymen so idk.

Obviously there's something wrong with RSS because it's a good idea that's been around a long time and it doesn't appear to be popular with the general public.

jrcii··on A strange Firefox address bar behavior
I disabled all magic in the address bar so if I type "foo" it tries to connect to "http://foo" or else returns an "Unable to Connect" error. I was surprised how many steps were required to accomplish this.
jrcii··on Doom as a tool for system administration (1999)
You could round it out with that 3D "Unix" file browser from Jurassic Park.
jrcii··on How the Apocalypse Will Bring Out the Best in People
One summer in the early 2000s there was a blackout along the whole west coast, I was in Palm Springs where the temperatures that time of year regularly exceed 110F. The water filtration shut off so all the city's water was declared possibly contaminated and the gas pumps were off so if you needed gas to get to water there was none. People realized the last clean source of water was bagged ice and started forming mobs banging on the locked doors of convenience stores. I saw people siphoning other people's gas. Basically all hell broke loose. The kicker? The power was only out for 6 hours. When people are scared it doesn't take long.
jrcii··on Java garbage collection can be really slow
I was going to say for people who are going to lengths like kernel bypass networking to get these trades out faster I wouldn't be surprised if the key stuff is in assembly.
jrcii··on Show HN: Shell utility to encrypt a file into a self-decrypting script
> without needing to worry about command line arguments. For example, people are generally satisfied with .tar.

I have to google the extract arguments for tar every single time I use it. What was it again, -xfv?

jrcii··on Boaty McBoatface and the False Promise of Democracy
> There has been studies that show American politicians are mainly aligned with the wishes of the rich rather than people who vote on them.

jrcii··on OpenBSD 5.9
Hilariously these releases are apparently accompanied by songs with choruses that make reference to "secure by default" http://www.openbsd.org/songs/song59b.mp3

To me, there's nothing quite like the feeling OpenBSD offers you of running `ps -ax` and seeing a nice, clean, minimal list of essential processes.

jrcii··on U.S. government worse than all major industries on cyber security
This makes me wonder at what point incompetent system administration becomes legal negligence.
jrcii··on Don’t design like a programmer (2010)
> Try copying a number from Safari iOS into Google Hangouts Phone dialer. There's no paste option

The paste option is there, however it's very tricky to get it to appear. You have to hold your finger down over the space where the number appears, but sometimes you have to try it 5-10 times to get the paste option to actually appear. Before Google Voice shut off external integration and ruined it I had an app called Talkatone which worked with Google Voice, Hangouts has never been as good as that app.

jrcii··on Linux QoS for humans
I've really enjoyed pf on OpenBSD over the years. My only frustration has been the ever-changing backwards-incompatible rule syntax which perpetually makes large swaths of documentation useless, including the most recent printed book on pf and numerous online sources.
jrcii··on The truth comes out: Microsoft needs Linux
Their recent overtures toward open source are heartening, and for me did start to overcome the reputation of the old Microsoft. I was disappointed that they squandered that good will with the Windows 10 telemetry debacle.
jrcii··on OpenBSD hackathons
This is the shirt I would kill for https://www.eff.org/files/images_insert/defcon20-script-kitt... If you have one in medium please let me know what transgressions I have to commit for it.
jrcii··on The sugar conspiracy: sugar—not fat—is the greatest danger to our health
Dr. Lustig is known for his interesting and thorough, if somewhat controversial, case against sugar https://www.youtube.com/watch?v=dBnniua6-oM
