Used to have IB: that broker is no joke. I would see ads on TV of $7 a trade while I was paying their crazy .001 cents per share or whatever their price was. Great paper trading account, and a Java/C++ API for everything. Plus level-2 data.

These kids with their RH accounts have no idea..

Re:Ideas That Changed My Life on Sunday June 07, 2020 @08:04PM (#23452238)
I think these are closer to aphorisms than "models of thinking". In that sense take them or leave them if the are applicable to your life.

I don't read too deeply into stuff like this..maybe that is talked about in one of these ideas that I haven't finished reading.

How does this not break sizeof ?

Can't upvote enough. I think these changes could also be made in a way that can be mechanically-translatable.

For example: removing the register keyword, always requiring a return statement, etc etc.

A lot of changes can me made that will make static analysis easier.

There will always be people with 50 year old code bases that will never change (and some c89 compiler will always be there for them), but the language is pervasive enough that it deserves progressive changes to make it (even) simpler and safer and slightly more high level.

Re:Systems that defy detailed understanding on Friday April 10, 2020 @02:19PM (#22835823)
I think this is useful even for systems (SW stacks) that are much smaller and "knowable": you start by observing, trying small things, observing more, trying different things, observe more and slowly build a mental model of what is likely happening and where.

His defining characteristic is where you can permanently work around a bug (not know it, but know _of_ it) vs find it, know it, fix it.

Very interesting.

100% agreed. We might have been on the same team. Don't forget Omnipath and Xeon Phi. Prediction: this new discrete graphics card as well.
Define science the usual way, the essence of science is reproducibility: if you can't achieve that you are not practicing science.
Totally bonkers: economists using science to approach "social science" issues. Social sciences should be ashamed that this is not the norm, we should all be startled and surprised that this is a new thing and evidently people have just been using a system of high-fives and good wishes to solve the world's social problems.

Yes that is the physiology barrier that you describe that will be difficult to overcome.

The flaw is everyone thinks they will be a better driver than an AI, even though very few actually will be.

So if I had to choose my children driving with an "average joe" / friend / etc vs an AI, I would say: the data says the AI will crash 25% less, therefore it is safer.

I don't get why people are up in arms over this: the average person drives like an I D I O T. A Tesla auto-pilot drives above average. And right now they are driving the worse they will ever drive.

Therefore: more auto-pilot, less human death.
