I've been Cross from birth - I was the Cross my mother had to bear! Dave Cross

Thanks for the tip - I've done that now so here's hoping! BTW I'll still lurk occasionally, Regards and thanks to all CP'rs! Dave Cross

I have given up work, so much as I've enjoyed the Code Project for these last ten or so years, I don't need the daily news any more. I try to unsubscribe, I still keep getting them. I write to webmaster like this: From: Dave Cross [mailto:dave.cross@ifdev.net] Sent: 20 January 2015 17:23 To: 'webmaster@codeproject.com' Subject: Unsubscribe not working Hi, I’ve tried a few times to unsubscribe from the daily build but I’m still getting them. Please fix it! Dave. I'm still getting the messages! Honestly, I expected better from you! Dave. Dave Cross

Afraid so. You should hear my mother complain about the cross she had to bear. Dave Cross

Nothing will have changed because I couldn't report it! Actually, I realise I've learnt something from the experience. If you don't give customers contact details it must drastically reduce bug reports! :laugh: Dave Cross

I must have been feeling weak, any way I was tempted by this in the latest newsletter. Webcast: Agile for Distributed Teams IBM’s Elizabeth Woodward and Jean-Michel Lemieux cover important considerations for those organizations looking to adopt a distributed Agile methodology. Watch the Webcast Here. When I registered, I was passed to a screen that had no obvious next action, refused to play the webcast, had no contact or feedback links and appeared to have disabled the back key. Clicking the only working links on the page elicited the information that my OS wasn't adequate (XPsp3) despite the prerequsite being XPsp2. I suspect the real problem was I was running Chrome but I hate a) advertisers who ignore a particular browser, b) implementors who don't cater for same and c) organisation that publish web pages without feedback or contact links so that I can voice my displeasure directly. The net result is IBM have my details and I will no doubt have to unsubscribe from a further horde of spam and I can only rant about it here to make me feel better. :mad: Dave Cross

Actually the Italian governments money. (which is also owned by Fiat)

It was always about the Technology. Alfa and Ferrari in the 50's, Lotus in the the late 70's. Now it's about who's got the money to buy the technology. Those guys with the red cars have always got the money. Still they were lucky today. And now Jenson knows what he's up against. Roll on round two, remember it's not a sport or a business, it's a soap opera.

Dave Cross

He means 'Yes'. probably.

Thanks for that - the article doesn't jog my memory especially but it's smack on the money and full of super ideas.

Dave Cross

My increasingly unreliable memory tells me that I read a series of erudit articles here about a couple of years ago which outlined some ideas for a 'next generation' of IDE or programmer workbench. Does anyone else remember them? If I can find them, I'd like to review them.

When I was a lad, working in a COBOL shop, there was a test program which used the names of all the punch room girls as variables. I can't recall what it did but it had memorable lines like: MOVE MARY TO BED and PERFORM SEX UNTIL SATISFIED. :-O

A long time ago, probably twenty years ago at least, I talked to a chap from the National Computer Centre who had studied initial performance in aptitude tests and later career success. He found (IIRC) that the only good correlation was 'O' level English language (apologies to younger and non UK readers) and that ICL's test seemed to specifically select bad programmers!

Who wants Linux to succeed? I've written commercial software for a living since I had to build S100 crates and reconfigure CP/M for them. I thank Gates that all my potential clients have the same OS.

Dave Cross

Thanks for the clue, I traced the .insert() operation and found it made two calls to new() for 33 & 72 bytes when inserting my class ( int and char[50], not Unicode). That looks to me like an overhead of 105-54=51 bytes per entry. std::list required 97 bytes per entry but std::vector only 56. I have to store about 10,000 records and 50k seems like too big a price to pay for the convenience of std::set. Do these results seem reasonable to you?

Dave Cross

Thanks for that. I have the book and I know the relative merits of the containers. I need the functionality of std::set but I could code around the limitations of vector or deque if it was worth while. My question is really how to tell, in a given situation, exactly how much extra memory std::set uses compared with, say, std::vector? I can knock up a little test program to dynamically allocate 10,000 items using each method but how do I tell how much space is allocated to the whole collection? I need something like run-time_sizeof(). I have the feeling I've forgotten something simple.

Dave Cross

From the 'I feel I ought to know the answer but I don't' dept. I need to create a large array of UDT's and I'm short on space. Using std::set would be a no-brainer if I could work out (and justify) how much extra space it'll need at run-time compared with a hand crafted array. I realise I don't even know how to measure it at run time! Any hints and tips would be welcome.:confused:

Got a complex class which depends on data files opened in the constructor. Does anyone have any neat ideas about how to handle error conditions? If the files don't exist I don't want the object to be created but I can't see how to do it. TIA Dave Cross
