RTFA. The button is idempotent, so multiple pushes result in only one shipment. It resets when your package arrives.

So the child only gets to order a new jug of dishwashing liquid every day or so.

It is not intended for passenger transportation. It is for things like cargo to remote areas, or reconnaissance.

Again, there are cheaper alternatives.

Also, a lot of remote areas are remote because of weather, not terrain. If you cant get a helicopter in there, a blimp is just asking to crash.

then it can use hydrogen rather than helium, since there will be no risk to human life.

In order for this to be true, it would need to be loaded, unloaded and operated away from populated areas. This gives it a very erratic (ergo, longer) flight path as you cant fly it over cities and a huge logistic cost to get the goods to a remote location for loading and unloading (and these facilities do not already exist). The extra cost does not make sense.

Beyond this, it's daft. The airship cost $90,000,000 (90 million) to build. You dont want it exploding before it returns that 90 mil.

The Hindenburg always gets brought up here - I'm sure it was a big thing half a century ago. Now, much of the general public probably doesn't know what "Hindenburg" is, and the ones who are scared of airships are the same group who are scared of normal aircraft. I think the bigger thing here, in terms of travel, is that it only goes 80 knots. You can do 80 knots easily in an economy car. Legally too, in many places. 747s cruise at several hundred knots, around 250 IIRC. There's no reason to take this airship for long distance travel unless your goal is chillin' on the ship and looking out the window.

The Hindenburg and other airships were filled with volatile hydrogen, modern airships use inert helium. The problem is, helium is quite expensive in that volume. The fear at hydrogen airships was well founded, the Hindenburg wasn't even the worst airship disaster, that only killed 36, the worst disaster was the R101 which killed 48. Airships were not only vulnerable to explosion, they were unstable in high winds and storms. After the Hindenburg airships by and large stopped using hydrogen but there were still a lot of crashes due to weather.

The design in the article uses helium which isn't unstable like hydrogen but the problem of weather still remains. But that isn't what will kill it, it's economics as helium is going to be expensive in the quantities they need and who is going to pay for an airship to freight something at 80 knots when if it isn't time critical, a bulk carrier will do it for less.

Well, it may be poorly worded, but I have seen several places which have the blanket policy of not keeping people around for their last two weeks.

Sounds like some shitty places to work.

Everywhere I've worked they've kept people around until their last day as the two weeks to a months notice they have to give (in Australia, your notice is defined by your pay period, so companies who pay monthly can ask for a months notice). This is because a month, let alone a week is not enough time for most people to fully hand over all their projects and work. It costs a lot to get another person started on a project from scratch with no hand over.

Then again, employers aren't allowed to be abusive to employees in Australia so there tends to be a lot of trust between employers and employees because either side will lose if they act like arseholes.

Or trademark issue? Nintendo is using the DMCA here, but if the work contains none of Nintendo's code, then why would copyright apply?

Certainly I can see trademarks being an issue here, and it's only right that Nintendo try and put a stop to it.

Copyright would have more to do with art assets.

Even if the developer cleanroomed every texture and model from scratch, it was clearly intended to be a copy.

If the developer had just built the "super mario 64" engine and made his own game assets (erm, Super Silvio 64) he'd have a leg to stand on.

In the time it took you to explain that you didn't know whether Meccano is still in toy stores, you could have found out :)

In the time it took you to type that, you could have wrote "I'm an idiot" more than 6 times.

I dont even know what country the GP is in, let alone what toy stores are around his local area.

in 1960-th there was a toy - a metal constructor. It was a big box full of different plates, axes, wheels, nuts, bolts a.s.o.

[snip]

About 2010, I needed such a constructor to model some of my ideas before I implement them in full scale metal. I went to the toy shop. And I found that no such constructor is sold now.

I think the "constructor set" you're talking about was called Meccano in the west.

Not sure on it's availability these days, but I wouldn't trust a toy store to have it.

The Paleo diet today isn't good for your health.
Unsurprisingly, here is a study in Nature that points out copying Paleolithic diets would not be very useful anyway (not in the least because we've evolved since then, through the Neolithic era).

The paleo diet is yet another fully trademarked fad diet.

The Paleo diet was originally known to most Australians as the CSIRO diet and it's meant for weight loss, not as a regular diet. Its the same with Paleo which has the same high protein, low carbohydrate principles. The CSIRO diet is coupled with exercise and other elements as a 12 week program. Like Paleo, it's designed to induce Ketosis which isn't a healthy state to be in for years, but is just fine for a few months whilst you drop a few kilos.

Unlike fad diets, high protein, low carb diets are proven to reduce weight when combined with moderate exercise.

No, putting IKEA stuff together is fun. I've never understood that complaint, and I'd guess that many of the people repeating the meme have never bought anything from IKEA.

Tis a fine barn Enligh, but sure tis no desk.

As someone who enjoys a bit of construction every now and then, my main complaint with IKEA is that its incredibly easy to get things wrong if you dont meticulously study the instructions. So you can put a panel in backwards or upside down in step 4 and get to step 12 and realise that you did it wrong. So you need disassemble half the bed to right that one panel.

Most people aren't that anal about instructions and the instructions are fairly ambiguous as you've got to figure everything out from pictures and arrows.

And yes, most of my furniture was flat packed (some from IKEA, others not), I have a mixture of frugality and a Clarkson-esqe attitude of "how hard can it be".

Your performance is limited by the tire contact patch vs the weight of the car.

And the contact patch between the brake pads and the brake rotors.

You may as well just say "I know nothing about cars" as that would have been a shorter explanation.

Brake pads and rotors of better design and materials are able to work better at both lower and higher temperatures. Yes, cold brakes do not work as well as warm brakes (and we'll ignore brake fade as you shouldn't be getting that on a street).

Beyond that, with modern ABS, your brakes should not be locking up your tyres with ease, leaving a lot of room for improvement. Seeing as friction is also the force acting between the brake pads and brake rotors you cant argue that improving tyres will improve braking performance whilst improving brakes will not.

The anti-driverless car always love to bring up the situation

The pro-driverless car crowd always love to ignore the fact that the autonomous car wont be driverless for decades. A human will still be required to oversee and in case of a failure, take control of the vehicle.

The big problem with this is that people will be taking manual control because the autonomous car will abide by the rules that human drivers like to ignore like keeping a safe distance, not driving in the passing lane, keeping to the speed limit and slowing down in potentially hazardous areas (I.E. roads frequently entered by pedestrians).

Human nature wont change overnight because a pro-tech crowd wills it.

Same thing that happens when a modern car with brake assist rear ends an old car with better brakes and traction.

If your car has shitty brakes you leave extra room. Good drivers realize that 'shitty brakes' is always relative.

If you're driving a crazy high performance car you moderate your brake use to avoid being rear ended.

This.

You also dont have to be driving a crazy high performance car to get good braking. Just get some performance pads, rotors, good tyres and maybe some braided brake lines and you can make a Toyota Corolla stop like a sports car. Your 0-100 time will still be crap but 100-0 will be amazing. You dont even need to fit six piston callipers.

You've got to understand your car. Sadly this is something most people never learn. They get in it every day but dont understand where the edge of the envelope is. When I get a new car, I take it to an empty car park and test it out. Most of this testing is about 1/2 an hour of practising parking to make sure I get it right, but I also test braking, turning and accelerating to get used to how the car behaves. I know it sound very yobbish, but it's actually rather sedate with very little tyre smoke. I normally only do one emergency brake test from about 40 KPH (~25 MPH).

Also the first thing I usually upgrade is the brakes. I've currently got Project Mu pads, DBA rotors and APP brake lines on my S15, I did these before getting a bigger turbo. I've thought about getting the 6 piston callipers off of a Skyline (they'll easily fit on my Silvia) but its not really worth it unless you're turning into a hardcore track car.
