Comment Same for small plane crashes (Score 1) 269

The media are all over small plane crashes much the same way, giving a highly distorted view of just how safe aviation is. Aviation organizations like AOPA have started to get on the media's case about this.

If they reported car crashes with the same enthusiasm the "news" would be nothing but car crashes.


Comment Re:Because Windows Sucks (Score 5, Insightful) 265

The only reason Linux is perceived as more secure than other operating systems is because most hackers don't care enough to spend time working to crack it, so there are less attempts.

Linux is a major server OS (arguably the largest), very big in embedded systems, and completely dominant on smartphones. Hackers are spending very significant time working to find exploits.

If the process is 60% efficient, there is instantly 40% loss even before you load the product onto a truck - let alone drive it anywhere.
If used in a heat engine then it's likely to only be about 40% efficient in the energy use there so if used to power cars, there's a total energy efficiency of 24%, and that's if you filled up your car right at the point where the stuff is made without having to deliver the fuel anywhere in a truck - compared to storing the power in a battery where the powerpoint to wheel efficiency for say, a Tesla is about 70%
Still a worthwhile technology pursuing though - especially if efficiency can be improved further - and congrats to the team for such a breakthrough.

Comment Re:Or stay on LTS (Score 1) 78

I'm using LTS for all my work machines. The last round I rarely felt I missed out on anything compared to my updated machine at home. I think it's perfectly reasonable to stay with LTS if you want. You can still update to newer versions of, say LibreOffice and similar applications using snaps if you need it.

It's just like what I say about calculus: it's important to understand the basic concepts of integration and differentiation but you are NEVER going to solve integral or differential equations in real life

Actually I have solved differential equations to replace code that was using numerial methods to calculate some stuff. Tee end result was code that ran a lot faster and gave a much more precise solution. It took a couple of pages of maths, and because I am not very good at maths it took me a while, but it was worth the effort.
I have also had to use the good old quadratic equation to solve equatiosn that were calculating acceleration or deceleration, and plugged in the resulting formulas to replace code that was using numerical routines to solve these as part of a robot path planner. In the original code the previous guy had at least left clear comments saying what the code was trying to achieve, and a note in the comments to say something along the lines of plugging in a better solution at some point in the future

This highlights both the advantage of good commenting practice, which made it easy for later programmers to see where improvements could be made, and the importance of being able to apply this kind of maths to problems instead of just going to the numerical toolbox.

It's radio. Anybody in the vicinity can listen in all they like. Back in the bad old days this was Industry Canada's position, that cellphones were not private and there was nothing anybody could do about it.

Unlike AMPS, the communications are digital. So what. If you are sufficiently determined you can decode the data you have captured.

"Because Windows has a bad habit of hiding file extensions, whenever the device owner accesses their NAS, they see this file as a folder, fooled by the fake icon." -

So part of the problem is windows too. Hiding file extensions and allowing scripts to be run without confirmation. That's the same rubbish which made macro viruses so rampant in msoffice formats.

Comment Re:Softare and wording problem (Score 1) 210

The first generation Xperia phones actually did something similar. They kept the battery at above 90%, by charging up to 100% then letting it fall to 90% again before recharging it again. Much better battery lifetime than keeping it at 100%.

But lots of people complained that Sony had a lousy battery charger system that couldn't even keep the battery topped up. So to avoid the bad press they changed it and kept it at 100% all the time, like the rest of the manufacturers.
