Indeed, I am fairly disappointed by this video. This is pure BS. There is no actaul fact presented. Statements are not facts. You can do lots of that.

MYTH: the little girl droped the ice cream on the floor
FACT: In reality the cat made it fall.

Maybe it is a fact, but without any proof it is just a statement in the air.

This is spot on! I do not believe there are parts of computer science with NO industrial applications. I work as a assistant professor and I saw hundreds of PhD students. All of what they were doing had some form of practical relevance.

Even if what you do is not directly applicable (yet), you have to have a wide knowledge of a chunk of the discipline. Even the most theoretical chunks have practical relevance. A friend of mine was researching complexity theory (some weird complexity classes that appeared since the PCP theorem came). And he works designing algorithms for planning (of both, nurses, schools, ...) He did not find anybody interested in complexity, but his understanding of complexity made him very useful to design models and build algorithms.

Would I give my heart surgery to a guy that does not have an MD, but has a bachelor in poetry? Absolutely not!

Does a bachelor in poetry have a place in a hospital? Yes absolutely!

In particular, liberal art graduate tends to be good communicators. And that is something pretty much all tech field need. We need lots of people to help the tech field communicate.

I am working in a university in a CS department, and I strongly believe that having people to help us "publicize" our work is very important. I'd love to have a youtube channel full of interviews of different members of the department. Maybe short videos explaining a particular paper I wrote. That would be cool and would fulfil our job to explain what we are doing to the public.

We had a couple of artist in our college last year who essentialyl tried to make a piece of art by taking a marionette and coupling it with a few camera to build an "interactive automaton".

Well, I'd suggest the right question is, how much does this one benchmark matter?

Well, the article does not even convince me that the benchmark was properly executed. When going from a 32-bit to a 64-bit architecture, you certainly need the code to be properly optimized for the new target architecture. For instance, if you do not use the new instructions, it is unlikely you will see a major performance improvement. If you normalize the benchmark result to clock speed and number of cores there is not much difference between the 2 processors.

So my guess is: they did not properly compile the benchmark.

I disagree with that. What we want is to have net neutrality in practice. Now competition in the ISP market is a tool that could lead to net neutrality. It is an indirect way of getting net neutrality. But I strongly believe that net neutrality is important enough that we want to have a direct regulation about it.

Now, more competition in the ISP market woud not hurt :)

There is a similar law (in spirit) in North Carolina about public universities trying to hire a university professor from another public university. You can not make an offer more than xx% over what they currently have (I think it is 10%). The reasonning is similar, it cost more money to the state to get the same person they were already having at a similar position.

I already carry a tablet around. So if I need to have a watch AND a phone, then it is useless to me. I want it to replace my smartphone to keep only a watch and a tablet.

I want to be able to make a phone call with it. Not dick tracy style, but I could slide the watch to my hand and use it as a phone.
I want email/text message notification. (I don't care about composing if speech to text works fine.)
Appointment and todo list and reminders. (Once again modification using speech to text)
Time travel estimate to my next appointment (or home, work google now style)
Giving direction like a GPS.
Weather forecast.

ideally, battery life of more than 2 days. and something much smaller than what all smartwatch are. I don't want a half phone on my wrist. With modern screen resolution a quarter credit card is probably big enough.

Let's be honnest here. If anybody is willing to buy anything I did for $2B, I'd sell it without thinking about it (even if it is a cure for cancer). Cash in your $2B and go explore some other crazy ideas you have that you release for free (you'll probably find a second way to cure cancer). You no longer need money at that point: you can live with $10M/y for 200 years...

We once had world trade based on sail. Much/ most of that cargo does not need to get to it's destination quickly..

That is something I actually wondered. If you go slower then you need more boats and more crews. Also you'll need to store more food on the boat. (I guess you could fish, but let's not go there...) So there is a fixed overhead which prevents you from going arbitrarily slow.

According to [1], it takes about 10 days to cargo from the UK to the US (east coast). That boils to to roughly 26Km/h. I don't know much about boats, but that seems fairly slow to me.

Anybody knows more?

Well, that might be a little bit extreme. I am all for promoting local economies. But we need to make a good cost/reward analysis. Quite frankly, the cost of bringing an smartphone (or whatever electronic) from overseas is actually fairly small compared to the cost of producing that smartphone. (Even assuming you bundle in the cost of phone all derivative ecological cost.)

I am not an expert, but if you distribute the production line all over the world, then you might lose a significant economy of scale when producing the devices. Also I don't you might still need to transport prime (or refined) materials: you might need chip foobar, which is not produced in the USA and need to be brought from overseas. Producing everything everywhere is never a reasonnable choice.

Also shipping from california to florida might actually be worse than shipping from brazil. So you might want to produce in florida. But clearly putting one production site per state is certainly ridiculous. Some things might have to be transported over long distances. Producing mangos or strawberries in New York, might not be so easy...

I thi nk that what you are seeing is the difference between fat packages and slim packages. What I mean is that in your typical gnu/linux distribution, libs are installed on the system and applications depends on teh libs. That makes dependency issues a real nightmare.

But all other succesfull operating system take a different approaches. on windows, application typically deploy their own libraries. On macosX everything is typically in a fat binary. On android, all libraries are shipped in the APK. I assume IOS works the same. They all depend on a slim "operating system" and on shipping "complex" libraries when needed.

I wonder if that is the main problem with application deployement?

I use auto a lot. auto (or equivalent syntax) are used a lot in functional programming languages. Mostly in short functions where I do not really care what the proper typename is. It is clear how the variable behaves and that is I care about it. Often, I know I get some kind of iterator, but the actual type might not be easy to find. In particular, it might depend on a template parameter. So I guess I could add plenty of typedefs to get an easy to write type. But what is the point really?

Indeed! Where are concepts! These is the number 1 addition to C++ most of us need! I am sure that they were not added for a good reasons. But programming template is currently a nightmare because of the duck typing of the meta programming system.

Dear standardization committee, we NEED a solution to the template compile time debugging problem.

In any formula, constants (especially those obtained from handbooks) are to be treated as variables.
