I don't know his basis for the numbers, but they seem like in the right ballpark to me. You have fuel costs, X hours of maintenance for Y hours of flight - you can average that out, replacement costs of failed components, care and feeding of the ground crew, the pilot, the airfield it operates from, etc. Adds up rather fast. Drones are cheaper to operate than manned aircraft - that is a no-brainer. Is it exactly that much cheaper? Can't say for sure.
And I think, for instance, that explaining how and why an integral works, for example, can be done in an hour or two - tops! I would much rather a math teacher do that than spend, literally, weeks dragging us through the torturous path of proving it.
The theoretical underpinnings are useful for a career in mathematics. And nothing else that I can see (if I am wrong please enlighten me).
I don't need to prove that integrals work to use them. I don't need to derive the formulas for gravity and prove them myself using relativity in order to use them.
For me, in math class, all that time is wasted. But, to be fair, there is no separation of math classes for those few - very few! - who may take up a career in math vs the rest of us. I'm a software and electrical engineer and I include myself with 'the rest of us'.
If I'm building a building I need to know how to put it all together - spending weeks showing me how to properly kiln-bake a perfect brick doesn't help me build the building!
I never had a handle on the theoretical side of higher math - though I tried my damnedest for years. Only when I threw it all out and just focused on coming up with the right formulas to use on the right problems did I succeed. Got an A that time - and on a half point scale too!
The only way to handle this properly would have been to negotiate a new feature in that open source project the would benefit the company. It could be anything. Then send them an invoice / quote for the $5K to add the feature. They send you a check, you send them the first 'cut' of the new feature - does not have to work yet, this is just to get a delivery of it into the company's hands within their time frame - and finish it as soon as you can.
There you go - legitimate work for a fee, custom feature added to the project - everyone happy. C'mon - this isn't rocket surgery!
I'll list a few. 1) Linux / Unix was designed from the start to be a networked OS - so network security was baked into how it was designed, from the start. Windows started as a single user system, THEN added networking. Network security has thus never been job 1 from the start, and even now that still shows
2) Permissions. Linux uses Unix permissions, built from the start to protect users from each other, over a network, and to protect the OS from the users. Windows never was, and too many things run with full permissions to trash the OS. That's one reason Windows has so many vulnerabilities.
3) Windows is the UI, the UI is Windows. In Linux the kernel (OS) is separate from the UI - the UI runs on top. At the user permissions. So if the UI is crashed or compromised, malware can trash the user's account, but can't touch the system or other users. In Windows, the UI runs with full permissions, and any exploit in the UI gives full access to trash the OS.
4) Media - in Windows popping in a disk or plugging in a flash drive runs software on that disk or flash drive automatically - for convenience. In Linux, you need permissions to mount the media and anything you do with it is explicit - nothing is run automatically.
Yes, actually. I work a 9/80 work week - 9 hour days, every other Friday off. Add in a lunch break and it's 91/2 to 10. 45 minutes each way commute is about what I have too. That's just a normal 40 hour week - no overtime. When I do overtime, it's more like 11-12 hour days, but that's not too often (1-2 times a year maybe?).
A lot of us aren't killing ourselves at work and have that schedule.
This is likely just feeding a troll, but nuclear plants run by using fission to produce heat. That heat heats water to steam to run through turbines to make electricity. That steam needs to be cooled. The fission reactor needs to be cooled.
So nuclear plants need HUGE amounts of water. Big lakes, big rivers, or the ocean. That's it - it needs to be by one of those three. Coincidentally, that's where people live in large numbers. If we could stick the plants out in a remote desert we would. We can't.
You plan as best you can - they did pretty good in Japan actually. First you had the earthquake - boom. As a result you shut down the nuclear plant. So no power to run the pumps. Use backup generators for that. Tsunami hits - bigger than the protecting wall can handle. Takes out the backup generators, so no cooling again. Get portable generators in - oops! Can't hook them up - power couplers are incompatible. Guys running the plant don't make all the correct decisions from there - they make a few mistakes, wait too long to do some things, trying to save the plant rather than wreck it forever.
And there you have it - all of that had to go wrong, in order, for ONE reactor at ONE nuclear plant in all of Japan to have a meltdown - that was contained pretty well all things considered - while 10s of thousands lost their lives to natural disaster-S that caused it.

With that many stops, could staggering them be the way to go? Run 3 small trains at a time instead of 1 big one and each one stops at every 3rd regular stop. If they all take the same amount of time at each stop along the way, they could all travel much much faster - effectively the stops are now 90km apart for each train, and each makes only 1/3rd as many stops. Scale to 4 or 5 trains to have a *really* high speed rail that still services everyone.
I call bullshit. 3 seconds is the recommended travel-time distance between cars, not 1.5. Who is using that number? Also, I don't give a damn how busy a road it - if I want more distance between me and the car in front, I can slow down, stop sooner, etc. "Impossible"?? hogwash.
Sorry - I knew it would come off that way, but it's really not intended. Like most things I just expect that if you do it long enough you should be come good at it - everyone should become good at it. If you ski often for over 10 years you should be good at it. If you play pickup basketball every week for years - you should be good at it after 10 years. You know what I'm saying? And I drive, usually several times, every day. Every day!
It's impossible to know, but I've had the 'spidey-sense' for quite a while (15-20 years?). Although I did notice something very dangerous years and years earlier - when you first learn to drive you have to think about it. After that, (a couple of years later) you will stop thinking about it and start to do things without thinking. Right when that starts I caught myself doing things wrong. I had to fix my 'autopilot' and train it right. It may be that people fall into that and never get out of it as they don't realize they have committed bad habits to their 'autopilot'. Badly trained autopilots. Then add cell-phones or whatever on top of that and... crash. Just a thought.
I sincerely hope your mom never encounters a really bad situation while driving. One of the few 'concious' things I do is check my distance on the highway from time to time - checking that it's between 2.5-3 seconds. I'll also increase that if someone is tailgating me - so if I have to stop I can do it slowly enough at first to give the moron behind me reaction time as well. Seems to tick them off a lot
I agree that a 'recertification' would be a great thing for drivers, as well as at least a passing attempt to teach them what happens with mud, skids, etc. I think it would help reduce accidents a lot.
You should reread my comment - I said about 95% of the time my assumptions and tracking are good. But I still look. Every Single Time. Also, no, roads don't have a uniform slipperyness in winter - short of a 10 mile detailed survey of the conditions, I do the best I can.
That's typically a lot more than most people do - they have no idea if they can stop in a given distance in winter weather until they HAVE to. By then it's too late if they guess wrong.
Taking the risk of sounding like I'm an ass-hat to you - WTF? I've been driving for 35 years - this is all handled at the level of unconsciousness.
When I look into a lane beside me I 95% of the time see exactly what I expect to see - either a car or nothing. Basically because my mind picks up the cars through mirrors and peripheral vision and tracks them, all the time. Even when a car enters my blind spots I still 'see' them there - predict their movements and actions, etc.
I'll back off or speed up sometimes, again without real conscious effort, to avoid things I predict other drivers will do.
I know how fast my car is going from sound and surroundings - no need to look at the dash.
I can tune the radio, change stations, adjust my climate control - all without looking, by touch alone.
In winter I do things that freak my daughter out when she's riding with me - testing my 'footing' when there is no other car anywhere nearby. Why? To calibrate how slippery it is out - and adjust following distance and speed to compensate. Again, no real thinking about it, I just do it. Always have.
The question I have is - WTF is wrong with the rest of you? This isn't rocket science! If you have to concentrate on driving after doing it for YEARS, you shouldn't really be driving!
Why do you need a lawyer? I assume you are looking to make a point, not a fortune. File for $1000 (or whatever the limit is) in small claims court. A filing fee and a few hours of your time. No reason why it should not work - it may seem an odd venue for it to the judge, but I think it would still proceed. Set a precedent and others may join in - a thousand 'paper cuts' adds up.
IIRC you are supposed to WALK against the traffic - i.e. facing it. But when you are riding you are considered a vehicle, so you must RIDE with the traffic.
Riding against the traffic is against all traffic laws that I know of. Walking I'm not sure - other than the pedestrian always has the right of way, period.
Riding with any kind of speed just makes the closing rate that much faster when riding against the traffic. That increases the risk of you getting hit frontally - at a lot higher speed - when coming around corners or other obstructed view areas. Also may cause more accidents when cars need to swerve because you're suddenly appearing in front of them, speeding towards them, on the wrong side of the road.

We have never been at war with Iraq. We have always been at war with Syria.

I believe the correct way to phrase this is:
"I'm a nuclear physicist that just likes driving a truck you insensitive clod!"
memes must be respected, after all
Huh? What a question! So you actually think anyone has time to build nuclear weapons, from scratch, when they are suddenly needed?
Why stockpile ammunition for the armed forces? Why stockpile gasoline in your local gas station? Why stockpile food in your pantry and fridge?

Yes! A moon base by 1990. We could move all of the radioactive waste from all the reactors on Earth to the moon if we had such a base.
What could possibly go wrong?
At least they've got a hobby!
