I would never speak to someone like that. However, I would love it if Linus would talk like that to me. I would learn so much from that man. Also, we don't know anything about their personal relationship. I have friends that treat each other like this every day, and yet are still very good friends/colleagues, but they know not to speak this way to me. Linus can talk to me like that any time, but my friends and co-workers can't. You establish these limits when you start any friendship or professional association.
Mauro did make a major fcukup. He accepted a patch which returned an obviously invalid error value for an ioctl request. The worst part is that the error code was changed depending on its value, as if to sweep the problem under a rug. The beauty of the LKML is that there is no rug. The reason Mauro got burned is because he is a seasoned maintainer.
Mauro did not deserve to be shamed on the slashdot front page. Yes, he did blame userspace for the problem he created as the maintainer of the media subsystem. Also, any new kernel developer should make sure they know the coding style and inherent laws of the subsystem they are focusing on. I am sure he understands the USB video device class very well, but he submitted code that goes against basic pragmatics (changing an error value).
We all enjoy drama, and this conversation is gold for any new or old developer. I learned something from this argument. It taught me to refocus on meticulous aspects of my code, and to rehash the basics of all of the programming paradigms (which should be obvious anyway). I gather this was Linus' intent. He just took a very direct approach to filling our minds with some valuable knowledge.
Why not take something positive from this mailing list instead of contributing something negative? Stop bashing Mauro. He has a family, and stresses in life that will be exaggerated by this blunder. Linus comments were well deserved, but he took to the harsh criticism fairly well after he foolishly brushed off the initial call to his attention. Unfortunately, he ended his follow up with an unfortunate comment. I am sure he is now trying to ignore superfluous flames outside of the LKML and refocus his attention on learning through reading the code in his subsystem. The most important first step is to read the kernel source. If you don't understand some aspect, you need to look deeper. It is never enough just to code. You have to always continue to read and learn throughout your entire career as a developer.
When I read a book, I look up every single word I don't know. This has become habit, and as a result the more I read, the less I actually need to look up words. Apply the same aspect to your coding. When you are reading code, don't skip over any function or operation you *think* you understand.
The UK computer industry enjoyed a mini-rennaisance in 2012 thanks to the popularity of the $40 Raspberry Pi
Are they serious? Do they even know where the ARM SoC is designed?
It amazes me that the Arm Holdings stock was only around $20 a few months ago, when they are without question the most dominant, stable, and secure tech company in the world. Both Apple and Google are completely dependent on the licenses they have acquired from ARM to allow them to use their risc based ultra low power cpu in their devices, and to allow the manufacturers (samsung, ti, etc) to build those chips, and yet in some cases their stocks are twenty times more.
This amazes me, but at least ARM's stock has doubled in the past few months. There is NO bigger player in the computer industry in the world than the UK. I make this claim upon the the fact that now mobile is the dominant platform, and ARM is the only real player in that game (as of yet). Anyone can license and manufacture these chips for cheap and give us crappy hardware as a result, but the ingenuity is in their reduced and low complexity instruction set which allows for their ultra low power design, which is why almost everybody is using their SoC designs.
The only reason that nobody realizes this and their stock has been stagnant in the past is because they don't have a "ARM inside" sticker on every ARM based device made. It there was such a sticker, they would be beyond any doubt the most popular company in the world.
Disclaimer: I am Canadian (and live there at the moment), but I am also a UK citizen. I also don't hold any ARM stocks, though I am kicking myself that I still have yet to acquire any, since it would have almost doubled in value over the past year.
inability to communicate good ideas is more an indicator the ideas aren't that good
If you find his book too complicated, then check out Stroustrup's other book, "Programming Principles and Practice using C++", which is more like a high school text book. Or check out his amazing and simplistic site for the aggregation of information crucial to c++, http://www.stroustrup.com/C++.html
He may not be the greatest writer, or the most congenial, but his ideas were great, and no one can argue against it. No language is as dominant and most crucial to the world's infrastructure, and his books (and his online material) are a great companion in your time of need.
I recommend he learn some well established api. He should get straight into it. Something graphical with very intense visual feedback. He should start by just getting the demos to work. They are *really* simple to get setup, and give great insight in to the capabilities of the frameworks. Then as he progresses he will learn other things he can accomplish and add to them. http://code.google.com/more/ http://developers.facebook.com/ http://qt-project.org/ https://developer.apple.com/library/ios
When I was a kid, I would only read a book if I knew it contained the solution to a problem. I would read the book cover to cover if I had to, but in general, I was always more interested in building rather than reading.
My only intent was to play video games, and I would do anything to get them to work. I would save every penny just to by another mb of ram. I was constantly changing the motherboards and processors as well. When I was 11, I was writing batch scripts. At that time, I was using 80386 architecture and DOS. I moved to windows to play games like ski-free, and to play around with winsock and tcp. I got into irc for videos and music, which also introduced me the concept of a newsgroup. At this point everything changed. Any problem I had could be solved with ease. Generally, somebody else would always have faced the same problem I had, and they had solutions!
I got into web development pretty early, but I got bored with it quickly, since at that time, the specification was pretty limited, and I was always more interested in playing video games and sports instead. I'm 29 now, and I have a bachelors in computer science, and a masters in engineering. I do numerical programming with C++ and OpenCL.
I only got into hardcore programming in university, but my general experience with computing placed me highly with my peers. My university was arguably the best in the country for that particular undergraduate program. Lots of my friends had fathers who were programmers, and taught them a lot at a young age, but none of them progressed faster than I did. I easily caught up to them.
My point is that you do not need to push him into programming, He may loose interest very quickly. My interest in things has always been very volatile, since there are so many other things to be interested in as well (sports, music, novels, etc). If his passion is genuine, he can catch up easily. The one corollary is that each generation is exponentially more intelligent than the previous generation. My generation was the first to have access to an over abundance of information. Before, there was a deficit of information and a surplus of attention, but now there is a surplus of information, and a deficit of attention. Access to such an infinite pool of information has made me much more ingenuous than my father's generation. Our kids will most likely be exponentially smarter than we are. Of course, previous generations more easily focused on one particular field, which had its merits, as they made incredible discoveries. The argument that there are less things to discover now is bulls$%*. We still understand very little in the scope of things. He does need to become the next teenage billionaire. His passion(s) just need to be nurtured properly. LET HIM PLAY! He has to work for the rest of his life.
Einstein's theory was only accepted after the empirical work done by Eddington. Einstein's theories were completely outrageous at the time.
I did not imply that neutrinos travel faster then light, it has clearly been proven otherwise. I meant for you to infer that there may exist some unknown particle that could still possibly travel faster than the speed of light.
when you get your mistake plastered all over the media you do look a bit silly.
So it is the scientist's fault that his ideas where sensationalized by the media? He said that he doubted his own results, and just wanted other scientists to verify his own work. People love making other people look stupid just to make themselves feel smart.
Ogre is a 3D rendering engine with a very large community based around it. We used it for a proof of concept for a real-time simulator, and there were few limitations we faced in using it. It might not be as clean as unity, but it has more flexibility in licensing, as long as you don't might copy left, which in your situation you shouldn't. Actually, I just looked and it seems they made the switch to the MIT licence.
The proof of concept was actually a major improvement over the production simulator, but of course business politics always wins in the end.
