The past few years have seen dramatic changes in technology. Computing is being increasingly done on mobile devices like smartphones and tablets. These devices have lower processing power and storage capacity than PCs. And they run on batteries that require recharging . Hence, applications built for them must have smaller footprints and be highly energy efficient.
Excuse me?! I started programming on a 1 MHz CPU and 48K RAM computer (Apple ][+, later upgraded to 64K, and later still with marginally faster CPUs), which has a *smaller* footprint than many embedded boards now have today. The IBM PCs I used during the early years of coursework for my B.S. Computer Science initially had 128K RAM. During the mid-'90s, the safety-critical, hard real-time backup computers developed for the state-of-the-art C-130J transport aircraft used 68040s. These experiences teach you to write clean, efficient code as a matter of habit. The only difference now is more capable hardware can be held in the palm of your hand.
at 35 if you are not learning yourself, you will become redundant very quickly
Now, this statement is absolutely true. Any good engineer understands their career must be one of life-long learning. If you are a software developer and you have not continued to educate yourself, then I agree some of your skills will be getting stale, but these will be the trendy skills you learned in college and your first job(s): today's language of choice, today's IDE of choice, today's OS of choice, today's architecture of choice. But, the Computer Science education I received in the '80s included a lot of fundamental knowledge. This body of knowledge hasn't changed, though it has been added to since then. Are computer science and software engineering degree programs no longer teaching the fundamentals that transcend the trendy development tools?
The seasoned pro learns to use the right tool for the job, instead of trying to pound the square peg (i.e. trendy) into the round hole. College can't really teach you that - it requires experience, and it is experience your young programmers may not have learned yet.
If you can hear quantization artefacts, then you're either suffering from confirmation bias or the piece hasn't been mastered to use the full range correctly.
It is because of the latter that some of us would be willing to purchase 24-bit encoded music to encourage the publishers to up their game and require better mastering. This isn't just wishful thinking, since has been shown to occur with published SACD discs. As long as the majority of consumers are willing to buy crappy mastering and listen with insensitive earbuds, the publishers have little incentive to improve.
I heartily agree and have done the same. It was a revelation when I first got my Carver power amp and discovered with its power meters that most of the time it was pulling less than one watt per channel. Of course, I had reasonably sensitive speakers too, but nothing extravagant.
Most countries have authorities that oversee all civil aviation, including general aviation, adhering to the standardized codes of the International Civil Aviation Organization (ICAO). Examples include the Federal Aviation Administration (FAA) in the United States, the Civil Aviation Authority (CAA) in Great Britain, the Luftfahrt-Bundesamt (LBA) in Germany, and Transport Canada in Canada.
1) Build vertically and increase the density of our living space, but it doesn't address increased food & water consumption or increased heat generation (if you haven't read Ringworld, you need to) as the population continues to grow,
2) Build on the ocean floor or floating cities; same problems as #1,
3) Wars fought over increasingly scarce resources, which will ultimately reduce the population, but is a rather drastic and ugly way to achieve it,
4) Allow part of the population to migrate off this planet, freeing up resources and reducing consumption of resources on the planet.
Now, #4 is hard and we're nowhere near ready for it. But if we don't work towards it, if it is not a serious goal, we will never get there. We also don't know what cool technologies will spin off and benefit everyone. You benefit handsomely from all the tech that has grown out of the first 50 years or so of "Space Nuttery".
