Astronauts (or other 'nauts) could find life on Mars quite healthy

Re: @ Loyal Commenter

"Humans can breathe pure O2 just fine at lower pressure"

Indeed they can and as the pressure on Mars is too low they'll need a sealed environment to live in so lower pressure oxygen is helpful.

Industry in 'denial' as demand for pricey PCs plunges

Chemist

Re: Engineering and Scientific Software

Well I number crunch a lot in spite of being retired but in fact my main need for power is editing 1080p/50 video which eats enormous amounts of processor time and memory. In addition processing a few RAW DSLR images eats lots of processor and memory and although nothing like video it needs to much more responsive as it's more interactive - rendering video can run in the background or overnight. So I'm looking for ~10X increase in performance over my rather aging dual-core AMD and maybe 8G of memory.

Re: So..

""with the power-hungry, large and inadequate""

The one you highlight is 10cm*16cm*4cm and weighs 250g

Quotes from reviewers "Need to buy battery pack or use on mains all time." , "Lack of opportunity to use 'normal' batteries may be a drawback for some people", "Cost of battery pack if wantind a portable radio (costs more than the radio itself!)", "The only failing is the price of the battery if you want it portable"

The damn thing is £30 and then you need to buy a mains adaptor

It''ll be no substitute for the Roberts' FM radio I use walking in the hills which lasts 8 hours+ on ONE AAA rechargeable and is the size of a box of matches.

Torvalds: I want to be nice, and curse less, but it's just not in me

Re: I would like to point out ...

So I assume all you other OpenSUSE people are having to use root password to connect to WiFi - is that right ? Am I the only one that doesn't ?

Or are the downvoters actually the ones who know nothing.

Re: I would like to point out ...

"https://plus.google.com/+LinusTorvalds/posts/1vyfmNCYpi5"

I've read it before -- it makes no difference to me , I'm writing THIS on a laptop that doesn't need a root password for WiFi - I don't know what Linus was doing but I do know that root is not needed - Network Manager runs as root automatically from startup - for that matter it handles my 3G dongles the same way.

"Before commenting on something you know nothing about" - that's just a stupid comment - I obviously know something about this to have so many machines using it that I've set up.

I would like to point out ...

..that regardless of what is said on the subject ( and given I don't know what Linus had configured on his daughter's laptop ) that you DON'T need to use root password to access a WiFi point with OpenSUSE

The usual install for networking on OpenSUSE defaults to the 'old' network system but can be changed to use Network Manager which is what is needed for easy access to WiFi roaming. The only time the root password is needed is to make this switch - from then on all WiFi networks only require their usual authorizations.

I have set up 7 or 8 in the last few years of which 4 are current. I travel extensively with laptop or netbook and never have a problem with WiFi

Re: Sad, and a huge loss of resources

"KDE is a fine piece of work."

I agree entirely - I've been using it since it first came out and indeed SUSE since v5.0 and never really had a problem, somethings I don't really like but I switch them off generally. Most people that seem to have a problem with desktops or indeed distros seem to chop and change and never actually become familiar with any one.

Re: Further proof that idiots don't know what theya re talking about

Just to add :-

I can assure you that minimizing animal use is VERY important in the life sciences - 2 reasons

1) Ethical

2) Money - using animals is VERY expensive.

I could go into the many reasons why it is necessary to use animals for certain purposes but the people who 'believe' that animal use is 'unnecessary' or 'misleading' or just ethically unjustifiable in any circumstance would never be swayed by argument.

Re: Lovely, but dangerous

"I'd prefer my pilots to be able to see things in the last few miles"

Me too. We were standing on the beach in the south of France a few weeks ago - very dark, beautiful starry night, far from any serious light pollution and then suddenly a brilliant green beam started up from inland pointing up and out into the med. sky. It flashed all over the place for about a minute, no obvious pattern like a laser light show, and then stopped. What it might have done to a pilot or even a sailor doesn't bear thinking about.

I think 1% of users choosing to build there own machines ( as I do ) or installing LInux over Windows or as a dual boot is an extremely good percentage as probably 90+% of users never think about it all as their machines are either provided by the company or already have Windows installed when they buy them.

(no I don't build my own laptops but I've netbook that has never seen Windows and a laptop that was recycled from a relative that gave up on it after a Windows update trashed the hard drive)

Not seen any since the days of having to compile the kernel - so late 90's ? - ghost processes, or rather zombies - sometimes but that's generally other software not the OS and indeed they get reaped anyway.

"Don't open ports for any services. Use OpenVPN or some other VPN instead."

Not an area I've done anything with other than setting up remote access via a vpn to my wife's school's computer but surely I'd need to have an open port to access my server via OpenVPN.

Re: Get attacks at SSH all the time...

Well I salute your solutions. I leave it open for a number of reasons but mostly recently proxying from our holiday home in Switzerland to watch iplayer. I did toy with setting a flag file on my web-site (on my ISPs server) and having (my) server scripts check that for a variety of reasons ( I have a PIC microcontroller that's controlled from my server that can do remote measurements like the house temp and remote switch on/off of kit) but so far non-standard port/username and really horrible password + up-to-date SSHD seems fine.

Get attacks at SSH all the time...

but I've got a non-standard port, the router redirects to my server where the only allowed user for SSH login has a VERY non-standard username and 20 digit 'difficult' password and I still check the logs. Almost all attackers go for the standard ports.
