Hi, if anyone has a little time tonight, I'm trying to put together a screenshot of some new software I'm writing but I need a few people from different geographical locations to browse a website to get a decent picture. So, if anyone is able to bring up "" in a browser and leave it open in a tab over 10pm, I would be very grateful.

it's a "real time" Analytics plugin for wordpress so you can see who's on a given site at any given point in time, which page they're on and which pages they've visited.

Essentially I'm after a "better populated" version of this;

Ok, for anyone who missed it, one of the core Linux maintenance teams appears to have screwed up really badly. As a result, you should really consider upgrading your system ASAP. You will hear people say "yeah, but it's difficult to implement the exploit", and they may be correct. However, once someone does produce a comprehensive exploit, my guess is that many (most!) home Linux installations are open.

Details of the issue are here;
The Ubuntu-specific details / fix details are here;

Hi, has anyone been watching "Mr Robot", which has just appeared on Amazon Prime?

Although it's not "about" Linux, technically, it pretty much is all about Linux.  :o 
(it's now one of my favourite shows .. :)  )

The Penguin's second hand Linux Emporium / Boxes to spec *really* cheap ...
« on: September 19, 2015, 05:45:11 pm »
Ok, so I've just cleared out a rack and am left with a whole bunch of kit with nowhere to go. Typically these are all rack mount servers based on AMD Hex-Core chips at either 3.2G or 3.3G with with 16Gb of RAM. These things make really good workstations when packed up in a desktop case ..

If anyone wants a really cheam server/workstation based on this sort of kit I'm happy to build one up with new disks / case and supply it with a years warranty from a company with a 13 year track record. Boxes essentially at cost with the distro of your choice pre-installed ...

« on: September 19, 2015, 05:40:56 pm »
Ok, I have six of these, I think they all have 2 x 75GB .. 15K RPM disks ...

They're sat on my Windowsill obscuring the sunlight .. if anyone's interested and would like more details / to make an offer on some or all of them, please let me know, otherwise they're headed for the 99p section on eBay ...

.. last seen in action around 4 years ago, all seem to have Windows 2003 Server licenses attached ..
.. as far as I'm aware they should all be working fine ..

In the beginning they were all young an innocent, full of promise ...
As time passed they became more powerful and more cynical ...
And eventually, they turn to the dark-side ...

Anything else to kill . GoogleWallet maybe .. oh, no, already gone.

How about ...

News and Events / Linux Chat
« on: April 06, 2014, 02:24:25 pm »
Hi,  I've run up an OpenFire server at  I've always been aware that the 'chat' facility here wasn't the best in the world, would be interested to see if OpenFire is a better solution - if anyone has 10 mins to kill .. :)

To try it out, run up "Pidgin" and create a new account.
This will be a Jabber (or XMPP) account of the form <your choice of id>, if you tick the right buttons it should try to create a new account for you.
Once in, you can friend others, or try to join the "LinuxForums" chat room ...

If it proves useful, I'll try to add a Javascript XMPP client for anyone not wanting to use Pidgin.
(incidentally, I'm using Empathy, this works just as well [better?] that Pidgin , with the exception it doesn't seem to like 'creating' new accounts)

Is it me? or was this just not in the news this week ??

It just seems incredible that the entire government of our nearest neighbor resigns and neither the BBC or Sky seem to have covered the issue, at least I've not seen it on TV and I can see no mention on their respective news sites.  Apparently Farage isn't the only Euro-skeptic doing well this week, albeit , apparently, not all the press want us to know about it. One wonders if the French will already have left the EU before we actually get to vote on it (?!)

Anyone with a account, please be aware I've just turned on reverse DNS checking .. so if you (or anyone) sends you email from random home computers directly, this will no longer work. i.e. your mail machine will need to have a reverse DNS lookup to match your forward lookup.

Solution for anyone with this issue:
Pipe your mail via an authenticated account, your GMail account will do the trick.

General Discussion / C++ .. who is the Joke on ??
« on: April 01, 2014, 11:21:30 am »
On the 1st of January, 1998, Bjarne Stroustrup (inventor of C/C++) gave an interview to the IEEE's 'Computer' magazine. Naturally, the editors thought he would be giving a retrospective view of seven years of object-oriented design, using the language he created. By the end of the interview, the interviewer got more than he had bargained for and, subsequently, the editor decided to suppress its contents, 'for the good of the industry' but, as with many of these things, there was a leak.

Here is a complete transcript of what was was said, unedited, and unrehearsed, so it isn't as neat as planned interviews.

Interviewer:  Well, it's been a few years since you changed the world of software design, how does it feel, looking back?

Stroustrup:  Actually, I was thinking about those days, just before you arrived. Do you remember?  Everyone was writing 'C' and, the trouble was, they were pretty damn good at it. Universities got pretty good at teaching it, too. They were turning out competent - I stress the word 'competent' - graduates at a phenomenal rate. That's what caused the problem.

Interviewer:  Problem?

Stroustrup:  Yes, problem. Remember when everyone wrote Cobol?

Interviewer:  Of course, I did too

Stroustrup:  Well, in the beginning, these guys were like demi-gods. Their salaries were high, and they were treated like royalty.

Interviewer:  Those were the days, eh?

Stroustrup:  Right. So what happened?  IBM got sick of it, and invested millions in training programmers, till they were a dime a dozen.

Interviewer:  That's why I got out. Salaries dropped within a year, to the point where being a journalist actually paid better.

Stroustrup:  Exactly. Well, the same happened with 'C' programmers.

Interviewer:  I see, but what's the point?

Stroustrup:  Well, one day, when I was sitting in my office, I thought of this little scheme, which would redress the balance a little. I thought 'I wonder what would happen, if there were a language so complicated, so difficult to learn, that nobody would ever be able to swamp the market with programmers?  Actually, I got some of the ideas from X10, you know, X windows. That was such a bitch of a graphics system, that it only just ran on those Sun 3/60 things. They had all the ingredients for what I wanted. A really ridiculously complex syntax, obscure functions, and pseudo-OO structure. Even now, nobody writes raw X-windows code. Motif is the only way to go if you want to retain your sanity.

Interviewer:  You're kidding...?

Stroustrup:  Not a bit of it. In fact, there was another problem.  Unix was written in 'C', which meant that any 'C' programmer could very easily become a systems programmer. Remember what a mainframe systems programmer used to earn?

Interviewer:  You bet I do, that's what I used to do.

Stroustrup:  OK, so this new language had to divorce itself from Unix, by hiding all the system calls that bound the two together so nicely. This would enable guys who only knew about DOS to earn a decent living too.

Interviewer:  I don't believe you said that...

Stroustrup:  Well, it's been long enough, now, and I believe most people have figured out for themselves that C++ is a waste of time but, I must say, it's taken them a lot longer than I thought it would.

Interviewer:  So how exactly did you do it?

Stroustrup:  It was only supposed to be a joke, I never thought people would take the book seriously. Anyone with half a brain can see that object-oriented programming is counter-intuitive, illogical and inefficient.

Interviewer:  What?

Stroustrup:  And as for 're-useable code' - when did you ever hear  of a company re-using its code?

Interviewer: Well, never, actually, but...

Stroustrup:  There you are then. Mind you, a few tried, in the early days. There was this Oregon company - Mentor Graphics, I think they were called - really caught a cold trying to rewrite everything in C++ in about '90 or '91. I felt sorry for them really, but I thought people would learn from their mistakes.

Interviewer:  Obviously, they didn't?

Stroustrup:  Not in the slightest. Trouble is, most companies hush-up all their major blunders, and explaining a $30 million loss to the shareholders would have been difficult. Give them their due, though, they made it work in the end.

Interviewer:  They did?  Well, there you are then, it proves O-O works.

Stroustrup:  Well, almost. The executable was so huge, it took five minutes to load, on an HP workstation, with 128MB of RAM. Then it ran like treacle. Actually, I thought this would be a major stumbling-block, and I'd get found out within a week, but nobody cared. Sun and HP were only too glad to sell enormously powerful boxes, with huge resources just to run trivial programs. You know, when we had our first C++ compiler, at AT&T, I compiled 'Hello World', and couldn't believe the size of the executable. 2.1MB

Interviewer:  What?  Well, compilers have come a long way, since then.

Stroustrup:  They have?  Try it on the latest version of g++ - you won't get much change out of half a megabyte. Also, there are several quite recent examples for you, from all over the world. British Telecom had a major disaster on their hands but, luckily, managed to scrap the whole thing and start again. They were luckier than Australian Telecom. Now I hear that Siemens is building a dinosaur, and getting more and more worried as the size of the hardware gets bigger, to
accommodate the executables. Isn't multiple inheritance a joy?

Interviewer:  Yes, but C++ is basically a sound language.

Stroustrup:  You really believe that, don't you?  Have you ever sat down and worked on a C++ project?  Here's what happens: First, I've put in enough pitfalls to make sure that only the most trivial projects will work first time. Take operator overloading. At the end of the project, almost every module has it, usually, because guys feel they really should do it, as it was in their training course. The same operator then means something totally different in every module. Try pulling that lot together, when you have a hundred or so modules. And as for data hiding. God, I sometimes can't help laughing when I hear about the problems companies have making their modules talk to each other. I think the word 'synergistic' was specially invented to twist the knife in a project manager's ribs.

Interviewer:  I have to say, I'm beginning to be quite appalled at all this. You say you did it to raise programmers' salaries?  That's obscene.

Stroustrup:  Not really. Everyone has a choice. I didn't expect the thing to get so much out of hand. Anyway, I basically succeeded. C++ is dying off now, but programmers still get high salaries - especially those poor devils who have to maintain all this crap. You do realise, it's impossible to maintain a large C++ software module if you didn't actually write it?

Interviewer:  How come?

Stroustrup:  You are out of touch, aren't you?  Remember the typedef?

Interviewer:  Yes, of course.

Stroustrup:  Remember how long it took to grope through the header files only to find that 'RoofRaised' was a double precision number?  Well, imagine how long it takes to find all the implicit typedefs in all the Classes in a major project.

Interviewer:  So how do you reckon you've succeeded?

Stroustrup:  Remember the length of the average-sized 'C' project?  About 6 months. Not nearly long enough for a guy with a wife and kids to earn enough to have a decent standard of living. Take the same project, design it in C++ and what do you get?  I'll tell you. One to two years. Isn't that  great?  All that job security, just through one mistake of judgement. And another thing. The universities haven't been teaching 'C' for such a long time, there's now a shortage of decent 'C'  prorammers. Especially those who know anything about Unix systems programming. How many guys would know what to do with 'malloc', when they've used 'new' all these years - and never bothered to check the return  code. In fact, most C++ programmers throw away their return codes. Whatever happened to good ol' '-1'?  At least you knew you had an error, without bogging the thing down in all that 'throw' 'catch' 'try' stuff.

Interviewer:  But, surely, inheritance does save a lot of time?

  Does it?  Have you ever noticed the difference between a 'C' project plan, and a C++ project plan?  The planning stage for a C++ project is three times as long. Precisely to make sure that everything which should be inherited is, and what shouldn't isn't. Then, they still get it wrong. Whoever heard of memory leaks in a 'C' program?  Now finding them is a major industry. Most companies give up, and send the product out, knowing it leaks like a sieve, simply toavoid the expense of tracking them all down.

Interviewer:  There are tools...

Stroustrup:  Most of which were written in C++.

Interviewer:  If we publish this, you'll probably get lynched, you do realise that?

Stroustrup:  I doubt it. As I said, C++ is way past its peak now,  and no company in its right mind would start a C++ project without a pilot trial. That should convince them that it's the road to disaster. If not, they deserve all they get. You know, I tried to convince Dennis Ritchie to rewrite Unix in C++.

Interviewer:  Oh my God. What did he say?

Stroustrup: Well, luckily, he has a good sense of humor. I think both he and Brian figured out what I was doing, in the early days, but never let on. He said he'd help me write a C++ version of DOS, if I was interested.

Interviewer:  Were you?

Stroustrup:  Actually, I did write DOS in C++, I'll give you a demo when we're through. I have it running on a Sparc 20 in the computer room. Goes like a rocket on 4 CPU's, and only takes up 70 megs of disk.

Interviewer:  What's it like on a PC?

Stroustrup:  Now you're kidding. Haven't you ever seen Windows '95? I think of that as my biggest success. Nearly blew the game before I was ready, though.

Interviewer:  You know, that idea of a Unix++ has really got me thinking. Somewhere out there, there's a guy going to try it.

Stroustrup:  Not after they read this interview.

Interviewer:  I'm sorry, but I don't see us being able to publish any of this.

Stroustrup:  But it's the story of the century. I only want to be remembered by my fellow programmers, for what I've done for them. You know how much a C++ guy can get these days?

Interviewer:  Last I heard, a really top guy is worth $70 - $80 an hour.

Stroustrup:  See?  And I bet he earns it. Keeping track of all the gotchas I put into C++ is no easy job. And, as I said before, every C++ programmer feels bound by some mystic promise to use every damn element of the language on every project. Actually, that really annoys me sometimes, even though it serves my original purpose. I almost like the language after all this time.

Interviewer:  You mean you didn't before?

Stroustrup:  Hated it. It even looks clumsy, don't you agree?  But when the book royalties started to come in... well, you get the picture.

Interviewer:  Just a minute. What about references?  You must admit, you improved on 'C' pointers.

Stroustrup:  Hmm. I've always wondered about that. Originally, I thought I had. Then, one day I was discussing this with a guy who'd written C++ from the beginning. He said he could never remember whether his variables were referenced or dereferenced, so he always used pointers. He said the little asterisk always reminded him.

Interviewer:  Well, at this point, I usually say 'thank you very much' but it hardly seems adequate.

Stroustrup:  Promise me you'll publish this. My conscience is getting the better of me these days.

Interviewer:  I'll let you know, but I think I know what my editor will say.

Stroustrup:  Who'd believe it anyway?  Although, can you send me a copy of that tape?

Interviewer:  I can do that.


Now the problem with this for a C++ programmer is that you look at each point and think; "yup", "yup", "yup" .. then you really have to wonder whether this is a spoof or if it's 'for real'  .. obviously it's an April Fool, but it really does make you wonder whether this is the interview he "should" have given !!

You can read the 'real' interview here;

Enough people thought it was real for Bjarne to explicitly reference this spoof in his personal faq;
