It is nearly universally the case that TCP packets have the DF flag set. This is because it's most efficient to have TCP segments sized to fit into a single packet each - if part of a segment doesn't arrive, the entire segment will be resent anyway.

So the DF flag is set, and the sending TCP reduces its estimate of the path-MTU whever it sees an ICMP "Fragmentation Needed" response.

I can't help but notice great the condition of the roads are (probably due to the very few cars there). This road in particular looks well looked after. For a country that has a lot of starving citizens, it is quite surprising. Take a drive through most streets in Los Angeles and you will experience what a poorly maintained road feels like in a supposedly first-world country. Same goes for some roads in my city here in Australia, poorly constructed to the point where heavy rain is enough to put massive potholes into a main road.
So the concern is the economy slowing down due to the large number of current truck drivers who are going to be out of jobs in the near future. I don't expect there to be a sudden drop.

First comes the autopilot trucks where they still need to be manned. Sure the drivers will likely take a hit in pay, they'll still have a job. Then comes the fully autonomous trucks, removing the drivers although. I see this being a gradual transition, not a cliff like the article mentions.

"Basically, the only real barrier to the immediate adoption of self-driven trucks is purely legal in nature, not technical or economic."

I feel like this is such a huge assumption considering any type of autonomous driving has not been seen use anywhere yet.

That's not a good comparison due to the difference in risks and returns.

Airplanes are expensive, are subject to international regulations and possess extreme damage potential.

Trucks can be confined to desert roads (like in Australia), are relatively cheap and are subject to national regulations. Also AFAIK drivers are relatively more expensive than pilot in comparison with total cost of ownership.
I find myself in the strange situation where I both agree and disagree with this sentiment.

The source of disagreement can be described as "time" - I consider not only the past, but the delay that happens after a technology is described to when it makes changes in our lives. It all takes time, and in the time to come, there is a chance that autopilots can take more responsibility from the pilot. Would you really be confident that in 20 or 30 years time, pilots will have the same job description as of today?

Of course, a pilot in a passenger plane has a lot more responsibility than simply piloting the plane. For example, dealing with passengers or talking to ground control.

The autonomous trucks will not take driver's seat overnight - the truck in question will be a decade-long testing phase, according to the article. What happens afterwards is anyone's guess.
You are right, just like AI that writes finance and sports articles would never displace journalists. Oh, hold on, it has. But surely a robotic assembly line would never replace honest and hard working American automotive workers..... just don't look at Detroit for conformation of that theory. At least all of our secretary and typist jobs are still safe..... well, not so much, but still, surely one can always go to a pharmacist school and get a high paying job after that. Right. What, AI is doing that now too, and better than humans ever could? Na....

Change is coming, and there are too many people who wish to hide their head in the sand rather then embrace this change, and figure out how to deal with it. We need a new economic model, because capitalism isn't going to work in a world where everything is created by machines (capital) and consumers have nothing of value to exchange for the goods that capital is producing. I am not arguing for communism, because we all know how well that has worked in the past. We need another solution.

Unless, if AI is going to replace all the labor, why not also replace the consumers with AI :)

The reason is because you never want routers to have to fragment your packets ever. Fragmentation is really inefficient. So any modern stack will always set DF and listen for ICMP unreachables. In other words, PMTU discovery.

None of the other reasons you mention are really relevant.
I agree and I believe that at first automation won't be integrated in the boeings and airbuses but will grow and evolve from inside the drone industry.
It would really be great if people stop calling it the "Hamburger" icon, and just dub it as the "Menu" icon.

When I ask someone (who is not clued into UX discussions, e.g. my parents) to look for the "Hamburger" icon, they expect to find a literal hamburger shape. Ask them to look for "three or four parallel lines", and they find it faster. I've then asked them to learn is as the "Menu" button, and that seems to stick. Otherwise, it is GOTO START ;) !

So designers everywhere, please change this horrible name and use a more easy to grok name.

Creative: YC Hacks, GitHub Music Hack Day, Yo Hackathon, and Brainihack all elicited some pretty fun stuff. I missed the Brainihack this year though, too bad! Techendo was pretty cool too, albeit small.

Cooperative: Some hackathons had lots of small prizes or none at all. Paypal Battlehack was really fun, a Change.org hackathon was stress-free and friendly, and I learned a lot at a Swift "hackathon" where even the smallest accomplishments were celebrated.

I haven't been to any college hackathons yet, but I'm looking forward to Hacking EDU in October!

This article claims that truck driver is the most common job in more than half of all states. That's obviously false.

There are as many registered nurses as truck drivers for example. And there are seven million teachers in the US.

"About 2.8 million workers drive trucks around. That’s a big number, but it pales in comparison to other occupations. More than 21 million people work in office and administrative support, more than 14 million work in sales and more than 11 million work in food services. Nine million work in transportation or material-moving occupations. Heck, there are nearly 9 million production workers who actually make things."

I expect a constant review of the sensor performance and adjustment. The truck in question is part of a decade-old testing phase, according to the article. This will provide a lot of information, which can help navigate the issue of sensor interference.

Sensor malfunction was a constant worry when I worked on small robotics projects. I hope that car companies, which have much bigger resources than I can afford on my projects, will spend sufficient effort on making sensor interference and various malfunctions not degrade the operation of an autonomous vehicle.

I'm still very skeptical on self driving vehicules to react correctly in non traditional events happening on the road...

Like, fraying your way in a traffic jam to reach the correct lane, which sometimes involve slow but untraditionnal paths.

Or Waiting half an hour for an accident to be cleaned, then looking at the police officer signs telling you to move on the lane coming in the other direction, because they've secured it for a while, etc.

I'm pretty sure we'll have a lot of autonomous vehicles stuck on the roads in a " wait for a human driver to unlock me" mode at the beginning.

Lot of unanswered questions:

How do other employers (not necessarily tech) motivate candidates to move there? Any natural attractions? Lots of outdoorsy people move to places like Colorado, Montana, Wyoming for hiking, camping, etc.

Is your salary competitive? If it's high compared to the cost of living, do you demonstrate that?

Is this just a job or a genuine opportunity? If the latter, how are you demonstrating that?

If it's really just a job (and that's OK), I'd figure out how to make remote developers work out. You have a lot of developers who already live in small towns with low cost of living, but it's their town and they don't want to move to yours. If you can leverage that, it's a win/win.

My experience of buying 20k disks at a time is that even those volumes aren't significant to the manufacturers. So essentially you are asking the distributor to label them.

Given that you have multiple vendors and you also seem to have a risk even in handling any drive, I would suggest that asset tagging the disks and using a bluetooth scanner, or android data entry app, would make sense for all your disk assets. You can then automatically document and track the entire lifecycle of a disk live, as it is inserted or removed.

Your refusal to generate your own labels seems strange.

> ...a sense of purpose, if you will.

Don't find purpose in what you.

The projects that make you proud today will be embarrassing to your future self. Many illustrators I know hate even looking at their 6 months old drawings. Learning is 99% failing, so finding purpose on your successes is not a sustainable strategy toward well-being.

Self-worth (resonant frequency?) comes from why you do something.

Search for the core values that define your actions. Persistence, empathy, discipline... whatever you define as the leading factors of your life. Then stick with them. As long as you are true to yourself, that is, you stick to your why, you'll find self-worth.

Accept that your values may change over the years. Coherence is a self-defeating value.

> ...insatiable craving to create some meaningful impact.

Many people fall into depression because they are either changing the world (whatever that means) or doing nothing. Don't fall into this trap, find meaning in the little things. Keep in mind that 100% of the "overnight successes" you hear from the media bubble were ALWAYS X years in the making, where X >= 10.

> I'm torn between the desire to be practical (be risk averse, lead a comfortable life) and an insatiable craving to create some meaningful impact.

Don't let the media fool you, risk aversion and entrepreneurship are not mutually exclusive. Before you go solo, being employed in a field you're passionate about is going to give you 4 kinds of leverage:

– network / mentorship,

– First-hand experience,

– Financial safety net,

– (If your business is tied to your day work) future clients.

If your employer is not a douchebag, you can start your business on the side.

I'm always wary of the "great customer support" gambit. I mean, of course everybody likes great customer support, but who actually makes everyday purchase decisions based on hearsays about customer support quality?

I'm not talking about business threatening decisions (like relying on a free Google API, or tying your hosting to your registrar). But for most purchases at worst you will lose the money tied to it, which is probably not that big a deal.

Few weeks ago I ordered stationaries from an obscure Japanese website I had never heard about before, for my Japanese tea subscription service [1]. Total cost was around ¥4500 (~$37). I didn't hesitate, worst case I would have lost ¥4500. Turned out everything went very smoothly and I will certainly buy from them again. But maybe they have dreadful customer support, how could I know?

Next time I look for something online maybe Google will propose me a "Buy Now" button. And maybe I will give it a try, what could possibly go wrong? At worst I will lose a few bucks?

Land between large cities increasingly turns to human desert in many places of the world. People find no reason to continue living in small settlements and no ecomonical backing for doing so.

Places where people lived for thousand years now become deserted.

This might be another nail in the coffin after rail (only stops at large cities) and air (flies over entirely).
oh. I though it meant "settings" and every time I see both the hamburger icon (that we're discussing) and the gears icon (a common icon for settings, preferences, configuration) I get confused as to how I'm supposed to guess where you've put what I want.
There are many programs which together provide a significant economic baseline. It's not all in the form of direct cash deposits, although much of it is, it's just that the programs are a disparate and tangled mess. That $40k trucker's salary nets out to only about $5k more than the baseline benefits for an unemployed adult citizen. [1] It's barely better than not working, and you have to spend the whole week on the road! Staying home and fixing up the house [2] while taking the subsidies will always be a better bet.

The only difference between what we have today and "Basic Income" is currently we phase the benefits out as you start to work, obviously to disincentivize working. You could think of "Universal Healthcare", for example, a lot like eliminating the phase-out for Medicaid. ACA already eliminated the asset test, now it's just an income test, so maybe that will go next. (mostly depends who's elected in 2016)

Go: A Surprising Edge Case Concerning Append and Slice Aliasing
What if it works the other way round? What if automation eliminates most, if not all, jobs, and thus reduces the appeal of living in cities where work is easily found? What if land remains expensive in urban areas, but the economic support for people to afford it isn't there?

What if automated delivery makes it cheaper to deliver to anywhere, so that it becomes easier and more practical to live far apart from others?
Eventually someone will be smart enough to figure out how to build an automated package delivery network in a city. Just imagine the economic benefit that will have. Imagine if every company could offer shipping services similar to Amazon Prime but at a fraction of the cost. Automated trucks would significantly aid long haul shipping legs in such a network.
It's like a Gram-Schmidt process. You take one question, then you look at other questions given (quotiented by, projected on, etc) that question, and so on.
This might as well happen. I think that decent Basic Income will cause just that: millions of people leaving expensive cities to live cheaply in the country.

This thought is backed by Russian dacha phenomenon.
A decade ago I had great Amazon support, missing books were resent and all problems solved fast.

In Germany I had very crappy Amazon customer service experience the last 2yrs. Problems with payments, fraud, washing machine delivery without taking back the old one although I had paid for that, etc. Worst was a stolen mobile phone (during delivery), where Amazon support gave wrong instructions during several interactions and then failed to cancel the attached carrier contract for months (blaming it on their system) which blocked me to get a new contract b/c I was banned for 6 months by German carriers.

In none of the cases Amazon did help in any positive way. Payments and fraud was only solved after I went to the police.

At least here Amazon support changed directions from 'happy customer' to 'cheap as possible'.
"Move fast, break things" is great when you want to create a social networking app and the worst thing that can happen is that somebody isn't reminded to congratulate your friends on their birthdays. With payments systems people can lose lots of real money and there are literally millions of people always looking for ways to game the system - that's why regulation and moving slowly enough is a painful necessity.
That's not the only difference.

We have a massive bureaucracy to handle all the various aspects of the distribution of those benefits. Most of which is not necessary in a basic income system.

The cost savings by eliminating that bureaucracy would be substantial.
Same for me, I buy on Amazon for the quality of the reviews, the fact that if there is a problem with the delivery or the product received, I just send an email an everything is solved. In order for this to work, Google will have to improve tremendously their customer service, if they are doing it like in the Play Store and Adwords, it's just not going to work.

And with that, the elimination of entire industries built up around the existence of car ownership like: mechanics, car washes, parking, valets, body shops, rental companies, car insurance, car loans, and on and on.

I'm not so sure that's true. If a truck/car breaks down on the road, it doesn't matter if there's a human behind the wheel or a software program. It still needs to get fixed. There will still need to be financing of these vehicles, ostensibly because they might be more expensive because of the software/hardware allowing it to be autonomous in the first place. We haven't really worked through how insuring these things will work, but just because they're autonomous does not mean that all of a sudden the entire automotive insurance industry evaporates.

On the whole, however, I agree with the initial point about how the peripheral economies built around servicing human truck drivers on their routes will take a hit. I'm thinking of all the towns on the way to Watertown from Minneapolis that would probably evaporate if they didn't have the trucks running the daily on the 212.
