Re: Reverse Vista effect

I've no experience of recent Photoshops as I stopped using WIndows a few years back but I did have a legit copy of Photoshop Expressions which worked perfectly under Wine - I seem to recall it had just one massive .dll Certainly if you must have something it's a powerful argument.

If you don't mind telling what do you need to do that isn't available on Linux ? I know there must be some things but it'd still be good to know.

Re: "G-forces are simply acceleration induced by the Earth’s gravity"

What has Earth's gravity got to do with it other than giving a name to a unit of acceleration that's biologically relevant ?

A rocket far from any gravity source will still generate a force on it's occupants when the engine is running that can be measured in Gs indeed that's an Einstein thought experiment that's used in GR discussions

Re: £36 and $65 contracts are the norm for iThingsies.

"when renewing their £15-20/month contract buut often it has no data so basically they are just getting the handset to use as a full screen phone (plus texts)."

It's quite possible (my wife has just done it) to get a mid-range Android phone, 1GB data, 250 mins, 5000 texts for £15/month in the UK.

Re: We need them for democracy

"requires every person to understand the world to some degree"

Not just democracy. In part lots of aspects of education are of themselves no direct path to a career. For example most people are not going to use calculus or chemistry or lots of other parts of the syllabus. It doesn't mean that exposure to some aspects isn't worthwhile. Many people don't know what they want to do - exposure to a bit of coding or hardware hacking may well be the start of someones career - I'm sure it was for some people here.

Although I'm not an IT professional an interest in electronics from 13 and coding all my adult life meant that when I NEEDED to write my own software for scientific purposes I could.

"Android and Linux will converge soon, someone somewhere will produce some kind of "Android Framework" that you could install on any distro so you can double click on .apk files."

Oddly enough I've just been trying a x86 Android build (for eeepc) in VirtualBox (on Linux) -seems stable and just like my wife's phone with the exception that there's no wireless, phone, GPS of course and there is a virtual Eth0. An SD card can be emulated but I've not got round to that yet so can't install apps. at the mo. There is a terminal emulator so I can tell you the kernel is 3.0.36-android-x86-eeepc.

CERN rushes to install new anti-matter hunter

Chemist

"I'm wondering how they make antihydrogen from antiprotons. Does the proton 'pick up' an ordinary electron, which stays in orbit due to normal processes, or do they give it an antielectron?!"

Well the antiproton would have a negative charge so they'd need a positron rather than an electron. I think antiprotons are relatively 'easy' to make but generating antihydrogen and bringing to reasonable temperatures seems a lot more difficult

Re: Why bother?

"why MS should even bother to spend money developing free software"

One reason is that they charge for skype <=> conventional phone calls. Very reasonable price. I use it regularly to call my mother in UK from Switzerland - costs <2p /min. I see now it can be just £4/month for unlimited calls on a subscription basis (but a fair usage policy !)

Works fine on Linux - we've got a USB headset that improves the quality a lot

Evildoers can now turn all sites on a Linux server into silent hell-pits

Chemist
Silver badge

Re: Maybe its time...

Thanks for that.

In reality I'm not too worried - I run a webserver on the internal network but the only external open port is a non-standard one for SSHD which as I mentioned has a password from hell *and a very non-standard username as the only valid account. The server running SSHD is firewalled, the NAT router is firewalled and all ports below 1024 are filtered at my ISP. I'm assuming that the major risk is e-mail attachments and given that I'm VERY suspicious and have trained my wife to be the same I'm fairly sanguine.

I agree I could try tripwire or some such or apparmor.

I really wanted to open up any discussion around Linux security and see if there was anything I'd missed.

*The password from hell is NOT written down, is 20 digits long something not like "bcGbf54TTt32dfcm2n1f" and generated on the fly by a little c program from a passphrase that I can remember. I use the same method, with different passphrases for all my serious passwords

Re: Maybe its time...

Genuine non-trolling query

I've used Linux for years without any anti-virus, as far as I know there are so few threats and the existing AV programs mostly seem to look for Windows malware that might be passing through. It's summed up in these quotes from the Wikipedia page : http://en.wikipedia.org/wiki/Linux_malware

"There are a number of anti-virus applications available which will run under the Linux operating system. Most of these applications are looking for exploits which could affect users of Microsoft Windows."

"The following is a partial list of known Linux malware. However, few if any are in the wild, and most have been rendered obsolete by Linux updates or were never a threat. Known malware is not the only or even the most important threat: new malware or attacks directed to specific sites can use vulnerabilities previously unknown to the community or unused by malware."

So far I've relied on regular updates, good firewalls, careful browsing on a limited account, separate account for banking, VERY hard passwords for secure stuff like banking and SSH, and rigid adherence to good practice. (yes I often get e-mailed Windows malware or phishing tricks)

The questions - is this enough - anyone know how effective the current AV products are ? - is this a non-issue ?

I've found it VERY slow when the computer has certain internet connections bizarrely enough

Re: Normal people don't use Linux

"Linux is too broken to use"

That's rather a broad comment given that lots of people use it all the time. I do every day - I don't use anything else. I obviously can't help with your problem esp. as as it's so vague. I do know that before I retired 200+ people used it in the company I worked for all the time and that was 8-9 years ago.

My wife, who had little in the way of computer education, used Windows at her school until she retired but then had no problem shifting to Linux.

Re: Only 2: GParted and Libre Office

"Why would an average computer user need emacs or vi ?"

They wouldn't need emacs or vi but then again a lot of Linux users are more technically inclined.

I listed my 'user' stuff earlier but in addition :

gcc - I write quite a lot of stuff in 'c'

tcl/tk - for quick GUI front-ends

VirtualBox

Now I'm not a IT professional, although I've been using and building computers since the Science of Cambridge Mk14 and written quite a lot of scientific programs and others for my own use.

Google Earth

A video editor - I mostly use kdenlive which supports 1080p/50

Thunderbird

Skype

UFRAW plugin for GIMP

Hugin for panorama creation

+2 I couldn't do without vncviewer for remote access and sshd/ssh/fish but they are likely built-in.

mplayer from the command line plays videos esp. 1080p/50 with the lowest cpu usage(~10% on my rather old dual-core AMD) although many other players support acceleration.

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.
