I don't think the Mandelbrot Set itself persay is all that useful, but its 3d relatives like Mandelbox, Mandelbulb, etc sure generates some amazing landscapes... I could totally picture that used in games or movies. It's amazing the diversity it can do with some parameter changes - steampunk machinery and evolving spacescapes, reactors / futuristic computers, art deco, extradimensional beings, alien cities, floating viny landscapes, transforming robotics, things hard to describe, etc.

I'd love to have a house / secret supervillain lair that looks like this one ;)

Taxis in the Netherlands are generally great (though expensive), with the notable exception of Amsterdam. There they refuse you service if the trip is not long enough to their liking. They are typically rude, and oftentimes armed. It's fun to go to the taxi-stand at Amsterdam central station and notice the permanent presence of at least two police cars there. They're not there to protect taxi drivers from the population, that's for sure.

I've taken UberPop in Amsterdam and it's great. Unfortunately, the Uber drivers need to ask you to sit in front, to reduce the risk of being attacked by vigilante taxi drivers. It's a breath of fresh air in a thoroughly unpleasant market, and I hope legislation gets passed soon to make it legal.

The majority of major, targeted hacks (rather than just sweeping the net for vulnerabilities) - aka, the kind of stuff that the US military cares about - involves sending emails or making phone calls and introducing yourself as Bob from IT, and sorry to bother you but there's a problem that we need to discuss with you, but first a couple questions...

They don't need script kiddies, they need social engineers. Question number one in the job interview should be "Is your native language Russian, Chinese, Farsi, Korean or Arabic?" And even as far as the more traditional "hacking" goes, rather than script kiddies they're going to need people who are going to custom analyze a given system and assess it's individual vulnerabilities, people with real in-depth understanding. One would presume that in most cases that the sort of targets that the US military wants to hack are going to keep themselves pretty well patched to common vulnerabilities.

AIs doing hacking? What are you talking about? This is the real world, not Ghost In The Shell.

And why would that be?

Not everyone is wired the same way, and some of the greatest contributors to science did it out of curiosity rather than goodwill.

Personally, I think the H.L. Mencken quote sums it all up rather well.

I just want the search engine to stop changing what I'm searching for. I don't want to have to quote every word like I have to do with Google to make sure that the word is actually in the page, and by "the word", I mean "the word I type, not a word that Google things may be similar to the one I typed". It's worst when you're searching for foreign words, product names, acronyms, or whatnot and Google tries to treat them as if they're English words and declines them or chooses synonyms.

"Did you mean X?" is fine. Even "Searching for X (see original results here)", if you're very confident that the person made a common spelling error or whatnot. But just going in and swapping out words as if this is expected behavior? Terrible. At least let me disable it if you want to do that...

Beyond all this: I do like how one can do simple commonn operations on Google - math, conversions, etc. The more of these the better IMHO, so long as they have a standardized format - be they tracking numbers, flight lookups, whatever. It's okay in my book to be a bit Wolfram-y.

Keep the interface plain, simple, the sort of thing that'll work on any browser, from a modern Chrome to a simple text-only browser. Only use javascript where it's not essential for the site to work. Here's an example of something that would be a good use of javascript: if you need to track clicks, like Google does, do it through javascript rather than by having a link redirect like Google does. I hate how I can't just right click and copy link on Google without getting some massive Google redirect link.

Just my thoughts. :)

I wish I could mod this comment up. There is nothing more joyful than giving your children the opportunities that you never had, and helping them accomplish their own success.

Apparently you don't know the meaning of the words "for fun".

You can get a buff body with a reasonable workout regimen in less than a year, and many elements of your "looks" can easily be fixed (better hair, wearing contacts, getting teeth fixed, dressing more stylishly).

If you have game, then your dick size doesn't matter, because history is rife with examples of men with questionable looks and stunning women.

Ultimately, having good social skills is much more important than any of those things in getting laid.

About 10 years ago I worked on simulating a rocket with electric turbopumps for fun. The concept was the exact same as theirs - minimize the number of parts that have to operate in harsh environments to reduce cost, maintenance and risk of failure. You don't even need any penetrations of the propellant lines, the rotor of the electric motor is the compressor itself.

I have no clue whether the design will actually be practical. But it's certainly not new. I'm sure I'm not the first person that this concept occurred to.

They talk about how they need to regularly pick up and relaunch balloons when they come down. I don't see why they would need to design the balloons without any sort of reinflation system. The leak rate is tiny, right? So:

1. A little more solar panel area than they already need.
2. Hydrogen filled instead of helium filled.
3. Tiny container of sulfuric acid (hygroscopic - self-dilutes down to a given concentration with atmospheric moisture)
4. Electrolysis cell (sulfuric acid is used as the electrolyte in some types of electrolysis cells).

Problem solved. Sulfuric acid draws moisture from the air, and during the day the solar power electrolyzes it it to produce a minute trickle of hydrogen into the balloon, which replaces the minute trickle that leaks out. Your balloon's lifespan is now as long as your electronics and envelope last.

Indeed, the figures Musk cited a couple years ago was that over 80% of the part count of a Falcon 9 is sourced in-house; it's a critical part of their approach to keeping costs down. He wanted to do that with Tesla as well but it proved impossible, only about 20% of their parts (at the time) were produced in-house. Unsurprisingly the biggest problems in their early days came from external suppliers, like the gearbox issue on the Roadster.

ESAB is a Swedish company. What use is it to NASA to dote largess on a Swedish welding firm?

I'm actually rather disappointed with ESAB here. I have one of their MIG welders from the 1960s and it still works; they're a respectable name.

I feel bad for NASA mind you, in that I don't think many of their problems are their own. They get all sorts of legacy systems forced upon them due to political reasons ("You can't do decision X that would be more efficient because 1000 people in my district would lose their jobs"), they never get the funding to engineer new things from scratch based on lessons learned, etc. I do wonder, mind you, whether their heavy reliance on external contractors is something they could reform.

Nothing like releasing your review the day after units start shipping, ie when it's too late to find out the unit's faults.

Goddammit I hate embargos...the only reason they exist is to hide flaws and problems from people who could get a refund. Ray, stop being the industry's bitch. You have a ton of readers, tell gadget makers to pound sand if they tell you that you can't release a review before it ships.

1. That's not "a" study, it's from a metastudy. The simple fact of the matter is, while the news makes a big deal of any study that shows a statistically significant difference between genders, most of these statistically significant differences are barely above the level of noise.

2. Where are you getting that quote from the paper? A search for those words doesn't reveal that.

There absolutely are some very demonstrable differences in certain psychological regards - mainly sexual. The most obvious of these, for example, is the fact that women are more likely to be attracted to men and men to women. But that's far from the majority of studied sexual differences that get so much play in the press. " With very few exceptions, variability within each sex and overlap between the sexes is so extensive that the authors conclude it would be inaccurate to use personality types, attitudes, and psychological indicators as a vehicle for sorting men and women. "

3. Girls are far less likely to get involved in chess to begin with in all countries (again, the fact that children mimic sex distribution of behaviors of the previous generation, no matter what they are in the particular society one is in), so one shouldn't be surprised that this is reflectected in the highest levels. Chess, as a competitive sport, has always been predominantly a "men's sport", internationally. But as XKCD notes, this is changing. The Polgár sisters are a great example. Their upbringing was an experiment by their father; to see what would happen if children were raised with extensive training in a specialist intellectual topic from an early age. One ended up an International Master while the other two ended up as Grand Masters, with Judit ending up one of the world's most powerful players of any gender. Their father's choice removed gender self -selection from the picture.

4. Oh please, you're not seriously going to pretend that there weren't tremendous pressures in Victorian society for women to not be involved in STEM-style careers, or that they weren't usually expressly banned from such. Even women who took them up as hobbies (usually well-to-do women) were often strongly advised against it, that it was harmful to a woman's delicate composition to be mentally straining one's self (a risk of the catch-all Victorian women's distorder "hysteria"; the cure for "hysteria" was to refrain from all serious physical and mental activity). This is the culture that ours came from, and it's been a slow incremental process of moving away from it ever since. The fact that you'd call "citation needed" on that is absurd, that's like "A normal human hand has five digits [citation needed]."

5."I'll see your 50% and raise it to 100%" - how does this even make sense? Women are 50% of the population (roughly). Nobody is talking about disinteresting men from pursuing STEM careers. There's already interest there. The goal is to try to also get more interest from women, to work against the carryover cultural connotations of STEM as "men's work".

6. " Are there laws or even customs, that prevent girls from entering a STEM field and excelling in it" - it's like you didn't even read my post.

7. "But what if it is bilogicial — as seems perfectly probable?" - not according to the actual research. And if one person wastes their time trying to become a physicist when they'd have made a better fry cook? Well whoop-di-freaking-doo. The world is still a better place.

I once coded for a game, Eternal Lands, where I discovered a major security bug. The game had a feature where if a person said a URL, it would turn into a clickable link. This was opened via a popen call. No input sanitization. Aka, vulnerable to injection. A person who simply speaks a malicious URL and makes it look like something interesting to click (hiding the insertion command in the path) could run it on anyone's computer who clicks to open the link.

Big problem. Simple fix. But try as I might, I couldn't get them to let me fix it. They were fine with me writing a whole new special effects graphics system for them, but one simple input sanitization, noooo, the popen works, let's not mess with it and possibly "introduce a bug"! Eventually it took me writing a sample command on the forum that would make a file in the user's home directory (which anyone who knows anything about unix commands could make far more malicious) by clicking on the URL. Suddenly they let me patch the system immediately (and deleted the forum thread... I don't blame them).

I didn't want to have to resort to that. But I didn't want a potentially dangerous exploit sitting in the system.

I never got approval to fix all of the other potential exploits in their system. Their networking protocol was terrible. I only ever saw the client code, but there was literally zero authentication that the server was who they said they were and that packets weren't malformed. Their entire security model was "let's initiate a TCP connection to a hard-coded IP and unconditionally trust everything that we receive". I can't imagine what their server code is like. But they wouldn't even let me add in trivial bounds checking to make sure that the packets weren't oversized - the most minimal of sanity checking.

The fear of changes breaking stuff often leads developers to neglect security. Changes to improve gameplay or graphics? Of course, our users will love it! Changes to the protocol? Nonono, the protocol is working, why risk breaking it?

The short of it? Don't have too much faith that that MMORPG you're playing isn't hackable in a way that could be nasty to your system.
