Still hung up on a good alternative to Publisher

If it makes you feel any better, whether you're on Windows or Linux, you need to be looking for an alternative to Publisher... it's been deprecated and has an EOL about a year out. You can, of course, continue to run it, but I can't imagine running any MS software that doesn't get security updates anymore, especially one that's an Office component.

Comment Re:Oh....it's about... (Score 2) 37

What's soccer? Is that where you put socks on cars? We're talking about a sport played with a ball and feet. The fact you weirdos confuse it with handegg is your own problem.

There are at least half a dozen different games called "football," none of which are the One True Football(TM). Soccer is a shortening of Association Football (itself named to differentiate it from Rugby Football which was codified earlier), and was, in fact, used as slang shortly after the codification of Assocation Football around 150 years ago.

You can identify the condescending assholes that already know that because they use terms like "handegg" to feign ignorance of this when they demand you stop using a word that's been in use for a century and a half in favor of their preferred terminology.

Comment Re:Eventually need a language with pointers (Score 1) 65

To understand what the program is actually doing and how the computers actually work, you need to understand pointers. They aren't necessary in day to day work, but not understanding how they work will lead to subtle bugs.

If you are coding in a language that doesn't have pointers, then you don't actually need to understand how pointers work... any more than you need to understand how assembly language works in order to program in C++. It might be helpful in some cases to understand pointers, in the same way it might also be helpful to understand assembly, or transistors, but plenty of people successfully write software (even well-designed, correct, performant software) without it.

Comment Re:Odd assumption in first question (Score 1) 65

Obviously this task was defined by an incompetent that does not understand border cases.

Is that obvious? To me it looks like the task was defined by someone who was looking to simplify the requirements so that test-takers could focus more on the relevant parts of the problem and less on corner-case minutiae.

It's the programming equivalent of the Physics exam question that ends with "ignoring air resistance".

Comment Re:Start on Earth, or orbit. (Re:Start small) (Score 1) 163

Does anyone really think a 100 kW nuclear power plant wouldn't be secured?

Putting it on board a rocket means there is a significant chance that it will be scattered across the launch site or the area downrange of the launch site, if the launch goes wrong. I don't know how you could mitigate that risk.

Comment Re:Time to change the payment model. (Score 4, Insightful) 86

Instead, content producers should GET paid per web request. And the payor should be the person making the web request. ISPs would just skim off the top.

The internet is more than just the web, and this is just a bizarre proposal. If you think bandwidth caps are bad, just wait until you can get charged per-connection fees.

Comment What about other vehicles? (Score 1) 68

Hydrogen does not make a good fuel, tor a tonne of reasons, but nitrogen fuel would be less prone to nasty reactions and fewer problems. Could N6 combustion be controlled at levels suitable for heavy road vehicles or trains?

(Electric trains have their own problems, due to the fact that the junction needs to be poor and the cost of copper is so great that lines need to use far worse conductors to reduce theft.)

Comment Re:surprisingly stable? (Score 1) 68

Read Ignition!, an excellent and entertaining history of the development of liquid rocket fuel by John D. Clark (one of the main protagonists of the field), with the truly excellent forward by Isaac Asimov that includes the following excerpt:

Now it is clear that anyone working with rocket fuels is outstand-
ingly mad. I don't mean garden-variety crazy or a merely raving luna-
tic. I mean a record-shattering exponent of far-out insanity.

      There are, after all, some chemicals that explode shatteringly, some
that flame ravenously, some that corrode hellishly, some that poison
sneakily, and some that stink stenchily. As far as I know, though, only
liquid rocket fuels have all these delightful properties combined into
one delectable whole.

Search for a PDF, and you'll find it. I've had the fortune to meet a number of scientists cut from the same cloth as Dr. Clark, and they are among my favorite people. I'm sorry I never had a chance to meet him.

Comment Re:Really cool, application to rockets not so much (Score 2) 68

But would it really be non-polluting?

In fracturing its atomic bonds, N6 will likely release most of its energy as heat and we all know that if you heat N2 and O2 enough you end up with all types of oxides including a nasty pollutant called Nitric Oxide (NO). I can't see N6 simply disassembling itself neatly into 3(N2) in an oxidative environment such as the earth's atmosphere.

Any sort of combustion-level heat in the presence of nitrogen and oxygen creates lots of messy NOx byproducts (that are all atmospheric pollutants), so, yeah, unlikely to be a pure N6 -> 3(N2) reaction without at least restricting its decomposition environment to exclude O2.

My father designed instruments to measure atmospheric concentrations of NOx (and I wrote much of the software for them) for one of the biggest manufacturers of things like that. He explained the chemistry to me years ago, and NOx pollutants are nearly unavoidable in the presence of O2.

Comment Re:How did we all decide to use the phrase vibe co (Score 3) 59

It's obviously something that the AI companies came up with to sell their product and here we are just using it like fucking sheep.

Really? AFAIK it was a joke phrase some individual came up with to gently mock the idea of "coding" without actually knowing what you're doing... and then (some) people somehow went ahead and adopted it as a serious idea anyway. (I wish those people luck, they are going to need it)

Comment Re:Yes, but ... (Score 1) 34

But even if they step out of the landscaping strip in the median 15 yards in front of the truck?

Stopping distance for a fully loaded semi at 55 miles per hour is 133 yards. If you step out in front of that truck 15 yards ahead, there's nothing the truck can do about it -- well, it could try to swerve, but it's anyone guess whether that would help or just makes things worse.

Comment Re:Always One Question (Score 1) 34

More importantly these trucks have Lidar. It has proven essential for safe self driving systems. Cameras alone are inadequate.

I'd go a little further, and say that any single sensor technology alone is inadequate, due to the amount of damage that occur after an unmitigated sensor failure. Multiple sensor technologies should be active at once, so that if (when!) any one type of sensor gets fooled, the others can override it and nobody dies.

Comment Re:It's bad enough people get experimented on (Score 2) 34

With those self-driving SUVs but you've got the semi trucks and those things can easily kill and they can kill a lot.

My friend's cousin got rear-ended by a semi truck that didn't see the red light at the end of the off-ramp, or the car that was stopped at it. He was instantly killed, his car was crushed like a can.

It turned out the semi's driver had been on the road for 14 hours straight, and was not, shall we say, in a fully lucid state.

Would a self-driving truck have avoided this death? It's hard to say for sure, but we can probably at least say that its cognitive abilities wouldn't degrade over the course of a long day, due to lack of sleep.
