Re: Well you are overlooking something

"Hey, I don't care if I'm the one"

You're not ! - maybe we should have a Reg poll about OS use - has there been one ?

Size does matter: Outlook.com punters want meatier passwords

Chemist
Silver badge

For really important passwords .

I use easily remembered passphrases and these are parsed by a little (very well protected -only root readable) C program that swaps letters around, adds fixed characters, pads, adds different numbers to some characters etc. so that a simple passphrase like "Ballmer is a bum" comes out as (something) like :-

ttxbv34jb21Mxsm1FncZpp

Just copy/paste. Anyone see a problem ?.

This is only for the really important ones such as finance or SSH where I think it's worth putting in a little effort. Even if someone gets local access to the computer and knows about my system they'd still have to know the passphrases ( I don't use MYBanksPassword etc. !)

Re: People forget why noone uses Lynux

Agree Vic, I'm sitting here in my holiday home in Switzerland and using Firefox on a Linux distro to view "forbidden" BBC TV content via my (Linux) server in the UK courtesy of OpenSSH and SSH tunnels.

MYSTERY as six people SURVIVE deadly VAMPIRE BAT BITES

Re: Vacination program

The point is that the virus will not MUTATE any FASTER - it will be more successful by default.

Incidentally the mutations may make the virus LESS virulent - might be more

..in an outbred population to allow for some survival from most infectious diseases. People with mutant CCR5 chemokine receptors (from memory) are resistant to some strains of AIDS for example. It may be true that anyone showing the symptoms of rabies from these bats will die but how many are exposed and never develop clinical disease ?

Re: As If

What are you using that needs you to go to the commandline at all for installation ? I usually use OpenSuse but I have also installed Xubuntu and DSL to VMs without any need for thr commsndline

Re: As If

I have the view that anyone who suggests that the command-line is NEEDED to use LInux is either ignorant or spreading FUD. I never routinely use it for installations. The command line is handy for many things, sometimes ( very rarely) easier for setting-up new or exotic hardware. I also use it all the time for compiling software. But for using a system it isn't needed. My wife for example wouldn't know what it was.

Dell readies Linux Ultrabook for autumn release

Chemist

Re: Ultrabook with Ubuntu and Steam for Linux?

"~60% of them actually work,"

I'm suprised and impressed that you have persisted I admit. On the other hand I'm amazed at this - in 17 years of using ( personal and professional ) and installing Linux I've never encountered anything like this - even in the old compile your own kernel days. The most has been the odd wifi driver or fingerprint reader on a laptop but not for years - even hardware stereo graphics with liquid-crystal specs (and that was 7or 8 years ago) or VDPAU hardware acceleration of H264 1080p/50 video have been rock solid.

Good luck with your endeavours

Re: Ultrabook with Ubuntu and Steam for Linux?

"I am describing issues I am having right now, today"

We will just have to disagree - I use all sorts of hardware, most of it self-built but I never wonder if Linux will run on it - I just expect it will. The only research I do is to checks scanners and wifi cards but the situation with wifi is that I expect it to work. I've mainly stuck with one distribution (Suse and now OpenSuse) except for VMs and expect to install in ~30 mins. I've done 8 installations in the last 12 months on several dual-core Intel and AMD, dual-core Atom (server that runs full-time and is the ssh access to my network when I'm away), single core atom netbook (upgraded from the rubbish Linux distro it came with) , old AMD 64 and a celeron laptop - donated to me after the owner gave up on it after a Windows update failed ). all with Intel or nVidia graphics - no issues, no crashes or lock-ups it just all works.

Re: Ultrabook with Ubuntu and Steam for Linux?

"except for the hardware support. It’s terrible"

Sorry Trevor - years ago that might have been true although I've had nothing much to concern me in ~17 years of use. But now it's not an issue for me - desktops and servers I don't have any problem with - laptops I've had no problems for ~5 years.

"rebuilding your Linux OS to try to get wifi working, or sound, or getting your video driver .."

FUD - some people may indeed have trouble but I've installed OpenSuse 11.4 to 3 very different laptops/netbooks in the last year and had NO problems at all - not just with the built-in hardware but also 3G dongles, printers, DSLR cameras ( controlling them NOT just downloading pics), USB headsets, webcams etc

"The average reg reader does not have a clue about business."

Indeed that might be true but it looks like a company that has to buy it's OS and manufacture expensive phones THAT IT CAN'T SELL might also be rather poor at a business where it used to be a market leader.

Metro, that ribbon, shared mailboxes: Has Microsoft lost the plot?

Chemist

Re: You think MS don't know this?

Whilst I accept that my work is not mainstream for many people adding together other users in academia, image processing and video it's clear to me that Linux is on the desktop if only in niche areas - not necessarily as easy for administrators I admit although I've never heard of any problems with print serving, file-sharing ( I have my own print/file/compute server)

"I even have Linux-on-the-desktop"

I know what you mean Trevor but it kind of gives the impression that business doesn't use Linux on the desktop. My last few years before I retired were spent using Linux workstations for heavyweight scientific purposes like protein modeling, quantum mechanics and 3D graphics and the company I worked for had 200 such systems spread around the world (and several 1024+ node Linux farms) - these were replacing SG workstations as the performance/cost was so much better.

Judge: Patent litigants behave like animals

Re: Nice one judge

"Some of that is down to old-school (out of date) thinking on the part of synthetic and medicinal chemists"

Well I know what you mean but after 38 years of hoping that we'd be able to model reality sufficiently well to do most drug discovery in a computer I think we are still far from it.

The reasons are too many and varied for this forum but include :

1) The conformational flexibility of small molecules

2) The structural complexities of target molecules even when the structure is 'known' *

3) Even with a good structure to work with the reality is often far more complex with the target protein being actually in a different state or set of states in the physiological condition so that 'docking' of drug targets to the target is rendered useless.

4) Even if a set of algorithms could 'solve' 1 & 2 ALL the other criteria necessary for a safe, useful drug in terms of adsorption, metabolism, toxicity still need to be met - most drug leads fail here

* - the gold standard for structure determination is x-ray but this is done in the 'solid' state usually at low temperatures and that masks the kinetic and water effects seen in 'real ' situations.

I've seen vast advances in the area of computing being applies to medicinal chemistry but even in my own field of protein modeling there is still a LONG way to go.

Microsoft sets the price for a Windows 8 upgrade at $40

Chemist

Re: I upgraded from Win 7 to openSUSE...

Why would I manually upgrade a kernel when the update mechanism will do it and the kernel modules for me - what would be the point ? I've never had a problem upgrading kernels probably for that reason and I never claimed that I (randomly ?) upgraded kernels manually - those days are over.

Drivers are NOT compiled into the kernel generally - they are loaded as modules when required and have been for years - look in /lib/modules/{kernel-version}/kernel/drivers/

I only research NEW and expensive hardware - everything else on 7 machines of wildly varying types and ages just works - I'm sorry if that fact upsets you.

I build all my own except laptops and they always work.

It IS the fault of the manufacturers - they don't release the necessary details in many cases which means supporting new hardware is a thankless task performed by some extremely talented and hard-working individuals who I thank daily and if it takes a while for a new driver I'm prepared to wait.

Re: I upgraded from Win 7 to openSUSE...

"because you've not upgraded the Kernel when you know there will have been a problem."

I don't chose to upgrade I let the update mechanisms update when necessary I don't really understand what your point is ?.

As for none-working hardware if manufacturers chose not to provide drivers or give the necessary info then so be it . I'd always do a little research before spending any serious money.

That's what I have Broadcom 4312 on a laptop - runs fine without any probs on OpenSuse 11.4

Re: I upgraded from Win 7 to openSUSE...

On the contrary - 1 laptop, 1 netbook and 1 desktop running on wireless without ANY problems at all - the others are ethernet anyway. 1 3G dongle, 1 Epson scanner/printer, 3 serial-USB convertors, 1 Samsung laser - again NO problems. 2 built-in bluetooth and 1 USB bluetooth - no problems. 4 webcams - no problems

2 have Nvidia graphics again no problems - one running vdpau hardware acceleration which is needed really to playback 1080p/50 video

All are on OpenSuse 11.4 but in any case I've not had any serious problems for years

Last laser I bought was a Samsung and it came with Linux drivers - I didn't use them as it was plug and play ( even networked Linux machines found the printer ) so it might be worth a Google.

Re: I upgraded from Win 7 to openSUSE...

I've used Linux for years ( almost the beginning) on lots of hardware often with Nvidia hardware and I've NEVER had a problem when updating kernels. I've sometimes had to wait a while fort he newest hardware to be supported but that's often specific to a distro. On other occasions it was down to individual programs - so I bought a Canon D550 when it was new and had to wait ~10 days for RAW support !
