Re: 100 times more?

"I use Opera (12.16) or Firefox. I have about 20 tabs open. Opera takes 3.7 GB. Firefox takes 4.2 GB with the same tabs."

Suggest you look at the output of free and see how much total memory is actually being used. On this 8GB i7 with lots going on it shows 7.6GB (3.4GB used ignoring buffers and caches) and only 80MB swap used.

The value you are quoting for Firefox sounds like the virtual memory size. If I look at the amount used size for the just top 18 memory 'hogs' using the virtual size it runs to 40GB - showing how useless a measure it is.

Re: 100 times more?

"Running just a single browser in Linux tends to eat up 4+ GB of memory, plus whatever services, X and the window manager all use.""

What !!

Well I'm running 3 (KDE) desktop users , Firefox, Thunderbird a Virtualbox inst, VLC to a webcam server, VNC to a pi, 5 filemanagers, and several terminals on this i7 laptop that only has 8GB and only 3.4 GB is in actual use - the remainder is cache/buffers - swap is ~80MB

Firefox with 11 tabs open is using ~0.45GB and ~380 processes are showing in the task manager

Re: Whichever way you slice it

"In fact, 1GB RAM isn't even sufficient to run a 32bit desktop OS these days - unless you're a masochist."

Well I've had a pi 2 for a few days now and I've never seen more than 400MB used - more if you count caches etc certainly.

I've got a browser with BBC main news page, LibreOffice calc with a 23000 row * 20 col. spreadsheet with all cells occupied with calculations, filemanager, taskmanager, terminal window and synaptic package manager all open on the desktop and and a lightweight webserver running too - memory usage is ~370MB

Re: How about

"t really does not get anywhere near what you would need for a proper desktop."

It looks like a proper desktop to me. I've got a web browser, image viewer, full LibreOffice, compilers, VLC, etc - the test spreadsheet suggests the performance is not too shabby but I'll know more in few weeks esp. when I've installed more demanding software. I'd not expect a 4-core 900 MHz ARM with 1GB of memory and an 8GB SD card to be too spritly but I'm really rather suprised. No, I'm not going to render HD video or even process too many RAW photo files but I will be testing it - and no I'm not going to be compiling vlc ( but I don't need to) but I will be compiling a lot of my own C programs so I'll have a reasonably comparison.

Re: How about

"I recently got myself a Raspberry Pi to play with. "

So did I. I'd resisted for quite a while due to time constraints but I order a kit on Monday, it arrived on Wed. and was running an hour later. Today (Fri.) I have it running vncviewer via ssh and I'm impressed. I have a test spreadsheet for LibreOffice calc that recalculates 400000 sines. On my laptop (4-core i7 ) it takes <1 sec - on the pi ~5 secs. I'm still setting it up but wifi was easy, jut need to set it up the way I like and install more sw. I spent ~£65 on the kit but that included SD card, keyboard, mouse, power supply, HDMI and ethernet cables and USB wifi.

Re: Not sure of the math

"At 0.3c, plug it into the kinetic energy equation"

You are quite correct with the calculation but it's worth noting the relativistic energy is slightly higher even at 0.3c - at higher velocity it will be much higher.

e.g at 0.8c it's ~2.8e18 J

I think if you read the BBC article you'd find they don't think they have. Our conditions might be even worse - who knows. But if you look at the list of conditions I don't think many of people here would prefer them to our current status.

The moon is having a measurable effect by gravity on our planet but any gravitation waves produced by the moon are miniscule.

I'd imagine it's about high-ish average-ish even in the UK . But more to the point where are they going to get 500 kW of battery power that will get them a reasonable range as well. It's about 5/6 Tesla batteries at ~500kg each for about 1 hrs duration flight ( I know doubtless cruise will be much lower consumption )

Five technologies you shouldn't bother looking out for in 2016

Re: Five technologies you shouldn't bother looking out for in 2016

" Thank you for proving my point that no one really needs it to be Linux."

Apart from a few specialist programs that might well be true - it's just that some of us find it a far superior environment. After all I have to go to the 'trouble' of building my own desktops aand servers and hunting out laptops that are OS free and then installing LInux and it's all still worth it for me.

Most people don't need Windows in that to quote LucreLout below "but then, 99% ish of home users aren't doing serious programming; They aren't even building Android fart apps, they're just browsing the web."

(Not my figures and I don't happen to agree either.)

I repeat - why would you want everyone to use Windows ?? What's it to you ?"

Re: Five technologies you shouldn't bother looking out for in 2016

"You can't understand the very simple fact - is that Linux Desktop is a collection of incompatible libraries, wildly and poorly designed applications that do not follow any UI concepts and do not work with each other"

As I've used Linux since 1996 I don't need anyone to give me a lesson. I use it all the time for everything both professional and personally - I don't find the problems you seem to think exist - all the applications I use cut & paste fine together - partly because I use the same desktop environment and partly because I make sure I use the best applications for my purposes. I had to seriously try to think of an example that didn't work - and all I could think of was an old vector editor I used until a few years ago when I started using Inkscape.

Do you really imagine having worked all my life in a high-powered scientific environment I'd be wasting my time fiddling with something not fit for purpose. I'm perfectly happy using Linux, so are many other people so basically mind your own.

I repeat - why would you want everyone to use Windows ?? What's it to you ?"

Re: Five technologies you shouldn't bother looking out for in 2016

"Thanks, you just proved my point that noone in the real world needs Linux on desktop."

Your view of the real world obviously is at odds with mine.

Apart from the scientific angle I use Linux for everything I do. RAW photo development/editing, video editing, PIC programming (MPLAB works perfectly in WINE) and now there is a Linux version anyway, and all the usual stuff - except I don't use cr*p like Facebook (sob !) but e-mail, browsing, Google Earth, LibreOffice, VirtualBox and lots of other stuff.

In fact I can't understand your problem - why would you want everyone to use Windows ?? What's it to you ?

Re: Five technologies you shouldn't bother looking out for in 2016

"Anyone non-IT professional who uses Linux desktop does not really need any desktop at all"

What an extraordinary claim. Almost all the people I know personally who use Linux desktops are NOT IT professionals but are scientists & academics. The reasons are complex but the simplest is that a lot of scientific software was written for UNIX and has been ported to Linux. The subsequent ports have been improved, extended and adapted to newer hardware. The other major reason is the availability of compilers/interpreters for a range of languages as a lot of scientific software is written/adapted by scientists for peer consumption.

If you doubt the existence of commercial software of a highly complex nature for Linux can I suggest :
