Re: It's all very wonderful

"Sure, we get a bit squeezed and the food is dodgy. But people have never been able to travel so far, so fast, for so little."

Or to look at it another way - people have never been able to cause so much pollution just for a 1 way trip.

No doubt I'll be modded down for making that comment but just look up into the sky on a sunny day in most places in europe and look at all the shit from the aircraft turning the blue into a hazy white. And yes I know thats ice crystals but there's an equal amount of CO2 and other pollutants emitted along with the water vapour that you can't see.

Re: It's all very wonderful

"Flying was once a pleasure but now, and especially with the US Paranoia and fear that everyone of going to destroy their ****** country it is no fun anymore."

Did someone force you to take a job that requires you to make 20+ flights a year? I sure as hell wouldn't take it. As far as I'm concerned my job is simply a necessary evil to earn money to live my life and any job that eats into my own time on a regular basis isn't worth having. If you did 20 long hauls that a minimum of 40 days a year on business trips, probably closer to 60. Fsck that. You must be mad.

Re: "C++ has its place , but this sort of low level almost to-the-metal code is not it."

"From your heartfelt complaints, I infer that you were once exposed to some complete idiots who took the C++ language spec as a challenge,"

Pretty much in every company I've worked in, usually by people who've read a design patterns book and seem to think they need to apply as many patterns as possible and abstract as much as possible with whatever problem they're given regardless of whether it warrents it or not. Usually it turns out these sorts are nothing more than lego brick coders who have no real feel for coding but they can bluff their way along by virtually cutting and pasting methodologies into their code.

"C++ was largely developed by experienced C coders "

Don't get me wrong - I like C++ , its a far better OO version of C than that Objective-C abortion Apple seems to love. I just don't happen to like the way it tends to be used. The problem is that with C if you don't know what you're doing you won't get very far - your program will more than likely crash pretty fast and often. But with C++ if its kept at a high abstract level with liberal use of the STL and other libraries lot a lot of people can just about manage to get something working.

Re: Corporations (like Google) need to step up.

"As a mostly C++ 11 coder its also gotten me interested in best practices in old school C (yes yes I know C++ is almost a superset of C but boy are they two different worlds even in mindset) so perhaps can help out eventually as well."

I do hope you're not suggesting that if rewritten in C++ it would somehow be more readable because as someone who also is a professional C++ coder I can assure you it would not be. For something as low level as SSL you need entirely *explicit* code, not the implicit untraceable to the naked eye mess most C++ programs end up as with cascades of constructors and destructors constantly firing off from stack objects coming in and going out of scope and no one being 100% sure exactly what is going on especially if you chuck in the STL with all its behind the scenes memory allocation games. And what would you do with 2011 here? Throw in some lambda functions or auto types or maybe default template values just to confuse the hell out of anyone tracing the code in a normal editor?

C++ has its place , but this sort of low level almost to-the-metal code is not it.

Well I didn't see it , but whenever I've seen "exciting" clips from F1 its usually the sort of thing that happens all the time elsewhere, not once in 2 hours.

"It is also idiotic to talk about "bump and grind" at 200 mph."

Nascar manage it. But then they're closed wheel.

"F1 cars have never routinely bumped each other because it's extremely dangerous in an open wheel car."

Err, thats kind of what I said. And thats what makes open wheel racing so tedious IMO.

"F1 has always been and remains the pinnacle of motorsport. "

*snort* Yeah , right. Maybe 30 years ago. Now its just profligate self obsessed bling circus that just happens to involve cars. The racing is dull, the cars are dull and the drivers are dull and some of the races - eg monaco - are just a pointless farce. They're not a race, they're an event for the glitterati to be seen at.

Re: +1 for Touring Cars

Yup. Touring car is proper track car racing. Unfortunately it doesn't have the bling bling and primadonas of F1 so the TV companies arn't interested. Still, F1 is slowly disappearing up its own arse with its dull racing, constant absurd rule changes and personality free drivers and people are voting with their remote controls. Silverstone was on at the same time as the wimbledon mens final and the Tour de France yesterday and I'll lay good money on its viewing figures being a distant 3rd out of the 3 of them.

"I enjoyed the British Grand Prix yesterday"

You're one of the few then. I gave up on F1 years ago, just a tedious procession round and round in a circle with hardly any passing due to most of the tracks not being designed for open wheel racing where even the slightest touch means you're off. Compare that to touring cars where bump and grind is the order of the day. F1 is an utter snoozefest. And now you don't even get a decent sound from the cars with the new hybrid engines - they sound like bad tempered lawn mowers.

Re: You think aircraft carriers are expensive...

" I remember at one point the US was refusing to hand over the source code....."

Wouldn't surprise me. We're the USAs Bestest Friend Ever when they need something from us (like helping them justify pointless invasions), but when we need something from them and they don't get much from it, its a different bloody story.

"We have a great history of building amazing aircraft here in the UK & Europe, I can't see why we didn't build out own VSTOL fighter,"

2 main problems:

A) We don't have the money and since no other european country has ever seemed that interested in VTOL we'd probably have to cough up for everything which wouldn't go down well with the usual "wot abaht 'ospitals-n-skools!" style of moron voter all politicians seem in thrall to these days.

B) The current crop of politicians don't seem that interested in supporting british industry anyway and when challenged just fall back on the EU fair competition rules. Which everyone else in the EU ignores anyway except us.

"at the very least we should never have sold off our Harriers!"

A textbook definition of extreme short term thinking. Even if we didn't have the money to run them they could have been mothballed with minimum maintenance until we did. But no, Osborne had to sell them off for a pittance. The man should be ashamed of himself.

Re: All software has flaws

"On the other hand, there is a pretty cool article on formal verification "

If formal verification were a panacea it would be a lot more common. All it does however is move the bugs from the software to the formal specification (which is effectively a sort of program in itself) and you end up having to debug the latter instead, and which scales in complexity with the complexity of the system you're trying to prove. And if you have a bug in the spec that goes unnoticed then it makes the formal proof worse than useless because people assume that , well , the software has been formally proven , it can't fail! Hmmm...

Or Titan is slowly drying up

Why? A huge bloated atmosphere and the liquid on the ground is confined to a few relatively small areas. Now if I was a betting man I'd lay a few quid on the fact that Titan is undergoing a very slow runaway greenhouse style effect and that in a few thousand/million years (take your pick), Titan will be completely dry of liquid hydrocarbons with them all having evaporated into its atmosphere swelling it even more. Whereas in the past - looking at the landscape - its fairly obvious there was oceans worth of liquid on the surface , far more than today.

Simple solution to this type of mess - go to suppliers and say "We want this , this and this by this time and you'll get your money when its done. If you over run or under deliver we'll subtract X for each infraction. Now give us your quote.". Sorted.

Re: The next step will come from ...

Right, because the X server is the obvious bottleneck on a massively parallel backend system. Not.

As for bloatware , yes you have a point there. First of all perhaps its time to dump a lot of inefficient scripting languages and VMs whether running Java style languages (unless the JIT execution can really be proven to be faster than precompiled binaries for the task) or entire OSes, and go back to to-the-metal style coding at using C/C++ and research even more improvements to compilers.

Following that strip down the OS itself - far to many server OSes run with code they don't need that while it doesn't do anything still occasionally is pointlessly spun up and queried (eg drivers) or just has to be passed through (eg firewalls). This is the case for Windows and Linux.

Then reduce the number of daisy chained API libraries and rewrite important code in a single library with minimal code jumping and hence paging required.

Once all that is done then we can start worrying about hardware.

Re: "allowing electric cars to drive in bus lanes"

"Ridiculous. A car with one person in it in a big city is probably wasting road space

(unless you have to carry tools and parts to do your job, and then you'd probably need a van anyway)."

Depends where in a big city and which city. Transport in city centres is usually good - in the suburbs, not so much. If I need to go visit a friend or relative I'm not waiting 15 mins for a bus to show up then have to change halfway , wait another 15 mins then sit there as the bus stops every 300m to pick up passengers and end up taking 2 hours to do a journey that I could do by car in 30 mins. And thats assuming I don't need to carry anything large or heavy. To coin a phase - fuck that.

Believe me - designing a fix for a vehicle when there are structural , safety, efficiency and space considerations to take into account, not to mention the warranty to consider if you feck it up and the owners want a replacement - is a lot harder than updating and testing some software which has to worry about none of the above.

AI turned out to be a lot harder than ANYONE expected. Even the supposedly (from a 1950s point of view) "trivial" AI problems of computer vision and voice recognition are only now really coming to fruition. One of the problems of course - other than hardware - is that the brain simply does not work on boolean logic except perhaps at the very highest level some of the time. Eg: "If its sunny I'll go for a bike ride else I'll watch a DVD". But the computer pioneers assumed it worked like this all the way down. You can't blame them , its an obvious inference , it just happens to be wrong.
