And as my wife discovered..
You can get Johnny Winter to sign a CD, or in fact two, 3 weeks before he dies.
Try that with an MP3.
I may be too sexist and misogynistic to have heard of it?
ALL of bashes features are obscure and rarely used.

Is Linux a trademark?
Linux Pear, its Linux, its almost an Apple and it runs Windows apps...(but not windows).
Not even North Korea

I hear a green activist has just been deported from Russia as well.
So every cloud has a silver lining.
Re: How decisions bite you on the ass
Um... isn't /bin/sh linked to /bin/bash?
Not on any of my systems, no.
/bin/dash on all systems I control.
Re: what else lurks
Indeed. All debian derived stuff uses dash by default and bash only for user console work and you can fix that in /etc/passwd
Hm. So that was the reason thunderbird and Firefox...
suddenly were in the list of 'recommended updates'.
Oddly, it may have fixed an NNTP problem with thunderbird, too.
Whatever, at least the fixes are going in pretty much as soon as the problem is found.
The people it seems, want privacy more than they want security.

Re: Bash Vulnerability?
Well not me, intentionally.
The question is, does that mean I am safe?
Yes., what bothers me is that Apache by definition can read all the PHP stuff that it executes, and some of that contains passwords for databases and email addresses and the like.
Can apache be fooled into - say - shoving all my php scripts down a pipe to some remote eejit, and if so what so I need to do to stop it?
I am not sure I ever use CGI - the only active scripts are PHP intentionally.
the server is vintage debian. bash is available, but not sure if its the default i'd expect that to be dash.
Simple task: how can I test my apache server for vulnerability, how can I switch off CGI altogether?
Give me arbitrary execution on a server with Apache's privileges and I can do quite a lot with that. At the very least I can connect to whatever database powers your site ...
using whose login credentials? You dont think that a readonly access to limited data is te same as full access to everything and to get that password anyway, you need access to the scripts that employ them, and apache does nit have access to the scripts necessarily.
Re: National Security.
First rule of software vendoring.
Only admit there was a bug when the fix is already in place, and available as a high priced upgrade.
Re: That huge march in the US had effect.
The real question is what is the anti-scientific hogwash.
Right now its 6:1on, on AGW.
Everyone understands climate change ...
“Everyone understands climate change is occurring"
Ok, yes, we do.
"and the people who oppose it"...
I suppose that would be the Greens? and big Government?
... "are really hurting our children and our grandchildren and making the world a much worse place,”
Not much to disagree with there then.
Many a true word misspoken in haste.
We know who is denying climate change. The AGW boys. Who deny its stopped warming years ago.
We know who is damaging our children's future. People who tax the bejasus out of us in expensive, highly profitable but totally ineffective efforts to stop a problem that isn't happening.
Re: @Tim Worstal
rubbish. You could easily turn the whole lot into aluminium silicate and various other metal salts compounds, separate them out, re smelt them and make new cans.
By using vast amounts of energy.
You can recycle any element in whatever molecular compound you want, if you have access to infinite amounts of cheap energy. You can make diesel gasoline and tar from water and carbon dioxide.
What you can't do, except by nuclear transmutation, is make new elements.
The most entropic substance in the universe, into which, by current theories all matter will ultimately turn, is cold iron.
So even with nuclear transmutation, the universe relies on 'anything that isn't iron' to fuel the processes of existence.
We are surfing the entropy wave of the big bang, and when its spent itself on the beaches of reality, we will be left high and dry, and dead.
Re: Where's Worstall?
We can in principle add an infinite number of zeros to anyone and everyones bank account.
That is not what is at stake here however.
We can also define value as 'man hours achieving nothing of any value' as well.
That is not what is at stake here however.
To create something of use - say a house - takes either man hours of labour or a certain amount of entropy (free energy).
That is what is at stake here.
Growth in a post industrial society of anything of real value - I don't count shiny new thing as being of real value, when you are starving and thirsty and cold, as any street beggar will tell you (a hot meal and shelter is far more valuable than an I-phone) - is utterly dependent of cheap, in terms of energy and human effort, energy to power the machinery that makes everything else you actually need.
And low cost free* energy (of which renewable energy so called is not a member) is something we are running out of**.
If the price of food rockets, because the price of diesel and fertiliser rockets, because both are in fact packaged energy, and furthermore we now have 30 people between farmer and consumer, who all need to be paid more and more to have a decent lifestyle, when it used to be just two or three... then we are in a downward spiral.
*free in the thermodynamic sense, i.e. at low entropy
** except nuclear, which we have a huge amount of left.
Re: Re:model a whole years economic activity in the UK in less than a minute
Positive feedback is not the clue.
Understanding multiple lagging negative feedback in a non linear suite of equations is the clue to chaos.
The whole POINT about chaos is that it is both unpredictable, and yet utterly deterministic.
Re: All been done before
The problem is that economics doesn't actually conform to any models that actually seem to work.
And the way economics has been run since WWII is by using debt to kick start investment into a bigger and better tomorrow. On the basis that growth solves the debt problem. More weath tomorrow repays the debts of today.
That fell apart when it became fairly obvious* that other constraints than money supply were limiting growth, and banks and governments turned to funding consumption, not capital plant and infrastructure, sometime in the late 90's.
*except to banks, politicians and economists.
Re: If you give a politician 1£ ...
A computer was asked to write a bug free program.
Definitely bug free.
If the caffeine hasn't yet kicked in, the point is that computers may well be able to write better programs than humans, in a narrow technical sense: the problem is deciding which programs to write...
What costs, is capacity and content.
What you pay for, is connectivity, and adverts.
Charging for You tube packets so the money went back to the you tube creator minus a slice for you tube for hosting it? Sounds better to me than having everywhere littered with adverts.
Mind you, on pay per view TV, you pay and STILL get the adverts..
At last, someone who 'gets it'
Re: to be fair
Why use 25 words, when one will do?...
Because you get paid by the word?
Re: This announcement worries me
I agree. COBOL on a Linux server is the ultimate in stability - and will run legacy apps. till Domesday.
Microfocus has no where else to grow. COBOL sales are static and mature.
And if the terminals end up Linux too, well so what?
Re: Return of the Ramdisk?
The way I work, I would use an SSD to run my computer installation - all my actual work is on a networked drive pair of spinning rust, which even at 100Mbps speeds is fast enough - I cant type gigabits of data every minute anyway :-)
That gives me what I want most. Faster program loading.
Few domestic users run huge databases so in fact using an SSD as the primary boot device with something more secure for moving data storage, makes a lot of sense.
The salient point is that fast access to irreplaceable data is not the issue. Its fast access to highly reinstallable applications that is the thing one wants.
And if you are mad enough to go 'cloud' then that's where your data is, not on your SSD.
It probably IS linux,
dressed up to look microsoftish.
Because thats what I would do If I were microsoft. Make a microsoft window manager, and a mechanism for windows apps to interface to linux. Sorta super-wine
And get selling.
CP/M was better than DOS too...
In the end, what wins is - well what wins. For all manner of strange reasons.
yup. 455, 465, 470khz were widely used in IF strips BUT its unusual to have an IF strip exposed to the 'ether'. Shielded and screened and fed from a mixer.
IN practice to receive such a frequency the LO would be exactly twice that - 940Khz.
I suspect that if you were slightly off, there would be some unwanted heterodyning, though.
1.5dB worse SNR on DSL
is all the difference I can detect...
Hardly planet busting
Re: Human flea instead?
Actually a soldier is just a way to get a rifle to the point of application. Why not give the rifle a jet pack and call it a drone?
And that is the way to fight a modern war. No humans on your side in the battle zone., just humans with google glasses on, somewhere 100 miles away.
. 22 calibre rifle on a quadcopter, for those pesky militants.
Re: What are Apple buyers going to do.
installing OS/X on non mac hardware is possible, but its way beyond 'insert disk and boot'
success rates in restoring from tape?
back in the day, about 25%.
3/4 of all tapes were unreadable after a few years.
Or even a few months.
I'd rather have my rust spinning or still in a sealed enclosure, with the same read heads as what wrote it. than in a flipping tape cartridge.
So its continuously replaced mirrored disks for me.
As for moving 100TB across an ocean, well the Internet was supposed to mean you didn't actually have to.
And in any case 100TB in 48 hours is only 4.6Gbps.
Well within a single fibre capability.
And that way it gets loaded direct onto the disks at the far end without a tape reader.
That will probably fail to read it anyway.
Re: Quantum mechanics?
Exactly. transistors are already quantum level devices: this is just a bit more quantum.
Excuse me, but what is a 'watch'?
..and why would I need one?
Re: Not all collisions are high speed
A good day to test a kinetic energy orbital weapon?
Well its Monday..and Im still here. I think.
....And the orbit may also be altered so that its further away in future
I think statistically that is probably far more likley.
Years ago some of us in a drunken evening coded up an iterative solutin to the N body problem - a program we called 'orbits' in which more or less random planets and suns were arranged in random places at random velocities.
The only ones that were stable for more than a few orbits comprised a large mass and some smaller ones. Even those had a tendency to catapult any other masses out of the ecliptic plane into outer space.
In a remarkably few cycles those in a plane would settle into harmonically related orbits.
Our conclusion was that the solar system was they way it was because anything else is unstable.
And will either converge towards a solar system type layout or fly apart.
Stuff on deep elliptical orbits around the sun is very prone to have its path altered to go nearer the sun: That can throw it out of orbit altogether.
Re: You can't beat theromodynamics
I think that isn't quite right.
And there are ways of getting rid of heat into space at night by radiation, anyway.
I take your general point, but not your actual numbers.
Re: John Savard Watch the Funny Man!
..except that everyone trades in dollars or SA rand now.
The zimbabwean dollar is so debauched only a man with a gun can force you to take it as payment. And in general the man with the gun doesn't offer payment anyway.
Re: we're not all going to die.
The only question is how fast, and how soon, and HOW PAINFULY.
Re: It's a shame.
I thought it was in fact closer to Правда these days.
Re: step outside of your city mind
actually these days cows are factory farmed on agricultural fodder. Sheep are commonly grazed around arable land that is perfectly suitable for crops/.
However, browsers are often suitable for land that is not suitable for agriculture at all. Grazers like grass, and grass means 'suitable for cereals'
Re: Doing More With Less
There is a graph somewhere of 'civilisation' versus energy usage per capita.
Various metrics define civilisation like infant mortality life expectancy and education.
Cuba does the best with the least, but overall the trend is that the less per capita energy you have the poorer and less civilised and more likely to die young you are.
Sure there is always room to scrape a percent in efficiency, but overall supplying things like clean water and basic refrigeration and house heating take a certain amount of energy to do even before you factor in the inefficiencies that you might improve upon.
One man can drink from a stream and shit in the woods and catch a deer every week for breakfast, 5 million cannot. The price of high populations is technology, and technology means stuff and it means energy.
reduce that energy and your population goes down, all by itself in very nasty painful ways.

Re: UK too this winter
I remember firing up the petrol then the diesel gennies too.
We did discover that a 100BHP Cortina engine didn't like 100bhp for more than 7 hours before it blew its big ends.
