xd··on If our particles have no identity, how can we? (2015)
Different states.. state of an electron on disc used by every execution of a program vs the very different state of a program after it's been running for some time vs any other invocation of that program.

edit: it's what makes debugging so much fun :D

xd··on If our particles have no identity, how can we? (2015)
The most interesting point, if you read the article, which from the comments no one actually seems to have done; she finishes with the idea: "Our identity is a state, but if it’s not a state of matter—not a state of individual physical objects, like quarks and electrons—then a state of what?"

The geek in me thinks of a program at rest on disk vs a running program.

xd··on How the GDPR Will Disrupt Google and Facebook
Strike 3 - 4% of your TOTAL GLOBAL REVENUE (or 20mil EUR, whichever is higher)

Why would they impose a 20M limit and not stick to 4% revenue irregardless of it...

edit: I'm not sure that the down voting is about.. it's still a limit, a limit that means a company turning over 0-500M will pay up to a 20M fine.. not so bad the closer you get to 500M but not so great if you're a small company, especially so as the regulation is so open to the "law of unintended consequences" right now and only larger companies will have the funds / man power to navigate it.

xd··on Mark Zuckerberg Calls for a Universal Basic Income
Basic requirement for UBI would be for Facebook to pay their fair share of tax first, surely.
xd··on US billionaire helped to back Brexit
If you don't understand my use of the word "we" as in the opposition/Right, or "narrative" as in political narrative; we are off to a bad start.

A quick example of bad left would be their reaction to Brexit and anyone that voted in favor of it, which to them meant, overnight half the country became racist.

Now, comparing a doctor, whom don't base their care on political opinions - to, say, financial experts that have something to gain from their "expert opinions" are two very different types of expert. But again, this is what we see coming from the left all the time, everything is black and white, there is no middle ground, you are either with us or a whole host of 'ism words.

Funny thing is, doctors actually have to make shitty calls i.e. triage, and sometimes society can be so broken, that to fix things, shitty calls need to be made; something the left are utterly incapable of doing.

xd··on US billionaire helped to back Brexit
"by seeing enemies where you could have allies." Ironically that's what we are seeing from the left, they see anyone that doesn't share their narrative as the enemy, in need of reeducating, and use the most abhorrent language to describe them, even going as far as comparing people to Hitler.

And these "experts" you talk of, they're just as politically motivated as you are, think about that.

xd··on Ask HN: What did you do after quitting the IT industry and how have things been?
You ever watch svseeker on youtube? He's a DBA building a boat; I've been watching him for years now and he touches on how his job is just a means to an end in his goals.
xd··on The Deep Roots of JavaScript Fatigue
Wanna back up that beautiful rhetoric with some actual objective reasoning as to why; HTMl, Javascript, the DOM are "bad" and some ideas on the way forward?
xd··on Banksy: “Steve Jobs – The Son of a Migrant from Syria”
"potential to be great people" From all accounts I've read; he was in no way a great person - great business man, yes.
xd··on WebGL water scene
Good effort, but when I hold shift he doesn't row faster ;)
xd··on “Fashion Is Hard. PostgreSQL Is Easy” [video]
Autocomplete is in MySQL you might just need to enable it with -A or in the config comment out no-auto-rehash.
xd··on Greaseless ball bearings: A revolutionary spin
Thanks for the downvote. Obviously you do not agree with simple facts, but just in case you think I'm making my point up: http://machinedesign.com/archive/proper-film-thickness-key-b...

Let me quote a key passage: "Engineers must check that films are sufficiently thick so asperities — peaks of surface roughness between mating surfaces — don't touch. Otherwise, bearings can rapidly wear and fail."

xd··on Greaseless ball bearings: A revolutionary spin
Grease is needed to lubricate the balls so they are not in direct contact with the races. Without grease the balls/races will fail rapidly when under load. There is no load on the cages so I fail to see how this development helps at all.
xd··on App that lets you talk over email
Is this real time voice communication or simply email with an attached wav?
xd··on Re: CVE-2014-6271 – remote code execution through bash
There seems to have been some confusion about the effect of this feature on PHP in previous threads on HN. If you are running mod_php you are unaffected even if you use exec / system etc as the Apache PHP SAPI doesn't pass the environment variables to the sub process.

However if you pass any user data (_POST, _GET, etc) into a system/exec etc call that sets an environment variable then you would be vulnerable.

xd··on Everything you need to know about the Shellshock Bash bug
There are a lot of comments below stating mod_php is just as vulnerable as mod_cgi. This is NOT the case, mod_php is unaffected by shellshock.

Edit: Just to be clear, even using system / exec etc is not affected as the environment variables are not passed along to the sub process by the apache sapi.

xd··on Passwords for 5M Google Accounts Leaked
Mine is on there but the password is a simple one I use on sites I don't care about and never used it for my gmail account. Can only assume it's been scraped from another site.
xd··on Sndtst: 8-bit video game music
You should check out the carmageddon tracks.
xd··on Why I'm sending back Google Glass
Interesting experiment, but for the most part I wouldn't expect google glass users to walk up to strangers and record them directly like this.
xd··on Chrome's experiment of hiding the URL is awful
He has a good point .. why is it "Search Google" .. the internet isn't Google, last I checked anyway.
xd··on Propose HN: Screenshot Saturday
I've been working on a desktop PHP editor written in PHP (you read that correctly ;) using wxPHP (uses wxWidgets):

https://camo.githubusercontent.com/be79881a1e77b79e3a24ce88d...

Currently focusing on the xdebugd side which is an xdebug proxy but with a web interface. I'll post a screenshot of that next Saturday I hope!

xd··on Mercedes Is Owning This Formula 1 Season
I'd love to know how they are running the shaft from the turbine to the compressor .. these things spin at something like 100,000RPM if I'm not mistaken. Normally this would be handled by a few bearings with direct oil intake at high pressure with the bearings being only a few centimeters apart if that .. but to span an entire engine is some special kind of precision engineering.

edit: special because any imbalance in the shaft would rip the bearings apart.

xd··on The new PHP
What do you mean by depend on an ini file? I wasn't aware there was any settings for equality testing there..
xd··on Ask HN: Best way to store integer array/list per key
https://gist.github.com/AndrewRose/8805629

Considering you are storing only millions of rows I figured a mysql implementation using blobs should do the trick .. but it all depends on the load you expect .. worth playing around with the idea I think.

xd··on Ask HN: Best way to store integer array/list per key
Just working on something, will be right with you.
xd··on Ask HN: Best way to store integer array/list per key
Sorry I meant to say what size of integer you require, 8,16,32,64bit?
xd··on Machine Learning in JavaScript
No no, thank you!

I've been building a data management platform for the last 8 years and we are now at the stage where we want to provide tools to help our customers get more from their data than just statistics. As my programming experience is mainly in PHP and JS this set of articles is helping me grasp ML rather than trying to wrap my head around a new language. I'm currently working on k-means clustering and re-implementing everything in PHP to get the best possible understanding I can .. my aim after that is to see how well I can implement things at an SQL level.

xd··on 10 Most (and Least) Stressful Jobs for 2014
"It isn't complicated enough to need a specialist."

Have you ever tried to center a hole to micron precision? Do you know which drill speed vs feed rate to use for the metal you are drilling? Do you know which drill bit to use? Do you know how to sharpen drill bits correctly? Do you know how to secure work to the table? Do you know how to use a sine bar and gauge blocks to mount your work piece at a precise angle? Do you know how to inspect the surface of the work piece to make sure it doesn't have burrs, specs of dirt etc that could throw the work tolerances out? etc etc

It's not he most in depth job, but it's far from unspecialised.
