Comment US has always placed well !!! (Score 1) 199

Okay they won in 2015, congrats! But these are their results going back to '74 when they first participated:
1 2 3 3 2 3 6 3 5 5 2 2 3 3 2 3 10 3 4 2 11 1 7 2 5 3 5 6 5 1 2 4 2 3 1 5 2 1 3 3 2
They pretty much always were top 3. Looking at other countries, only China has a better track-record coming in 1st often. Other countries placing well historically are Russia and South-Korea, but on average the US seems to do better (historically I would say 2nd after China).
So really, the are making a moot point. It's like saying the US must have really fit and healthy people, since they win a lot of medals at the Summer Olympics.

Comment How About Google? (Score 1) 180

Google has been collecting this type of data for years from every type of driver. I'm pretty sure by now they have machine learning algorithms that can predict if a particular driver is a Taxi, delivery van, private person, etc ... Probably they can even predict if a Taxi driver is an actual Taxi driver or an Uber driver (since Taxis probably spot themselves at particular Taxi hubs whereas Uber drivers will have other behavior).

Comment Social Engineering (Score 1) 54

In any of these systems, the weakest link is the human factor. Selfies in control rooms give these types of attacks plenty to work with. The name of an employee with access to these rooms, where exactly he's working and some info about his job. The next step might not be to "hack the system", but to give the company a call and go with "Hi, this is Engineer Jef Jefferson from the System X company, could you pass me Employee Z" ... "Hello Z, we've noticed that your system may still be configured with the default settings for blablabla ... ".

Comment Re:How ? Probably the same as with other classes (Score 1) 317

Indeed, but it would still need to be very basic. In Belgium the Science students (so, usually the 'smarter' students) had a CS class. I think the furthest we went were some different sorting algorithms ( insertion, bubble, quicksort).
Back in the days, everyone used to have a Commodore 64 and the like. Some claim that sparked interest as well in people, since you booted directly into BASIC, so you could program straight away. Yet all the other boys also had a Commodore 64, but that really didn't push them into CS. They could all do the 10 PRINT "PROFANITY" 20 GOTO 10, but that's as far as it went.

Comment Proprietary Math Libraries (Score 1) 208

You would be amazed at some of the 'low level' libraries that GPU manufacturers have and license to other such companies. These companies have Math Phd's still trying to get better precision and faster computation at Sine and Cosine functions, etc... I'm sure they are not in a hurry to open source this type of research which took plenty of money and time.

Comment Re:Oracle is bleeding-edge (Score 2) 122

Yes, but in that case you're running more than one "instance". The difference is that the "instance" is the set of processes that run and do the "database server" stuff ( handle memory, operate on the database, ...). A "database" is just a bunch of physical files containing the database data. You can have many such physical databases on your server, yet one "instance" can at most operate on one physical database. You can run more instances (thus having the "different databases" effect) on one server, but those are different processes running on the same server. So basically, you have two distinct instances running in that case which each have connection to a different physical database.
Anyway, you can create different schemas in one database, so that kind of gives the effect of having different "databases" in one "database" too. I guess it's just a matter of convention.
