The police can demand identification when issuing any citation: jaywalking, littering, etc.

Hikers are erratic. It's common when a person is walking to see something interesting and immediately walk towards it. It's Nature, and you are there to see stuff, right? (I catch myself almost doing this on a nearby shared use tr

In previous reports I've seen, they generally speed gun at a blind downhill corner. It's a good choice: the biker is speeding in a location which might have a hiker, so the guys getting the tickets are in fact the ones endangeri

People routinely break their own bones when mountain bike riding. There is plenty of momentum available to do serious damage. It's a shared trail. Would it be safe for hikers if someone rode a bike at 100mph? Of course not. To paraphra

There are weight limits on many bridges yet pickup trucks are sold without a built in scale. Basically, if you think you might be breaking the law, it's up to you to figure it out. I ride very causally, and use an App to measure my rid

Speed guns have been used on Mt Tam for at least 25 years. Not sure why these reporters think this is new.

The notion that multi-threading is hard to get right is a common one, but it does not match my experience. I've been running 100+ threads in C++ routinely for 20 years now. So long as you are sensible (using mutexes for shared data str

I think the author was specifically meaning types of OO, like Smalltalk, where each object sends and receives messages. That model works as-if each object is a separate thread.

Having a dedicated processor for each object is a terrible idea in terms of energy. Consider current high-core count Intel processors on Windows. Windows shuts down entire cores to save energy. Windows only powers enough cores to cover your

Your terminology is flat-out wrong, sorry. Asteroids and comets are not differentiated by their orbital shape. But that's not what I'm disputing. Asteroids routinely have their orbits mucked with by the planets and get thrown into

Goodness no! An asteroid in an elliptical orbit, for example, could be a civilization killer and might currently be undetectably far away right now. We are missing a lot right now, and we need to spend money on much better surveys.

I liked your article and it got me thinking about your point a lot. I'm just whining about the title since I think it could be improved. Would like to also see some text that mentioned that the inefficiencies add up so that it mostly m

The phrase "fundamentally broken" is overblown when referring to a syscall that works fine for most applications. "Doesn't scale" may not sound as glamorous in the title, but it's a lot more accurate. Back in t

Sure. But according to Wikipedia, they abandoned communal ownership of property in 1932. Seems like the common thread is still that all attempts at fully communal systems fail sooner or later. Successful group ownership of a business by the

The forces they are claiming are not sufficient to stay in space. Also, some sources of error would provide actual boosts in orbit without being useful as spacecraft engines.

Mutation Breeding[1] has been in use since the 1930s and has exactly the same risks in terms of creating unexpected attributes (allergens or whatever) in plants. GMO is little more than a vastly more efficient kind of Mutation Breeding; thi

Occam's Razor says it is not true. If you read the linked article, it is saying, in the most polite and disinterested way possible, that it is not true although they allow, in the driest of terms, that it could be true. I expect if the

The "premise" for the em-drive has been determined to be a thorough misunderstanding of the physics involved, so you cannot rule out any potentially contributing force in the experiment. Yes you heard that right: guys who misunder

Like I said above "There needs to be strong oversight to prevent abuse". That pretty much rules out whims. We have people who talk to themselves and freeze to death in the Winter. I disagree when you say "it is better this wa

That was part of the problem. The other part is that "One Who Flew Over the Cuckoo's Nest" inspired the left to change laws so that it became hard for Psychs to institutionalize people who need help. Both parts need to chan

When you program a flash cell, you first erase it, then you program it with a new value. Each erasure wears the cell out, so the more bits-per-cell, the longer the flash memory will last. It may also be faster: to read a cell you have to ad

If the read speed had degraded, I didn't notice since the RAID controller is the bottleneck in this particular system. We burned out the drives with a 800Mb/s sustained 24/7 write stream. In post-mortem I did the math and the

There is some uncertainty in the numbers, so the manufacturers quote fairly conservative numbers. In recent years flash cells have become a bit more fragile and the process technology has changed multiple times, so good past results on endu

Gosh I'd need to know a lot more about this number before drawing any conclusions. For example, what counts as malnutrition? In the US, do addicts die from spending too little on food? If a baby dies due to untreated gestational diabet

These are Enterprise class drives. In SSDs, the big difference between Enterprise and Consumer is endurance. Flash memory wears out over time and the firmware manages the wear and maps out bad sectors over time. Eventually, too much wears o

Not quite sure what you mean: I was responding to a question asking why it would be nice to have a liquid core. In other words, I was commenting on the radiation question. To hide from Radiation, one plan is to have 16 feet of soil on top

Without a magnetic field, there is way too much radiation on the surface of Mars. A colony would pretty much need to live underground. If you are going to live underground on a planet with unusably-thin air, why not live on the Moon instead
