But there are very few positions that qualify. There is one retired WO down the hall from me. He flew sky hook style helicopters for the US Army. There have been numerous discussions over the years about how to reward people who know how to manage information and knowledge better than they can manage people. There have been Staff Scientists at some companies which were actually senior engineers. Bob Pease at National Semiconductor is one example. But this only seems to work at large companies. I think the biggest problem is that HR types don't want to acknowledge these types of people exist. It doesn't fit their nice little arrangement of pigeon holes.

2009/8/26 Ralph Deffke ralph_def...@yahoo.de: sorry I mixed 'set' with 'given' and if my mistake did prevent all the smarter guys to give u an answer I'm sorry too. I hope not to be too limited to give u an answer well, think about how PHP 5 works. $a e.g. is a REFENCE to some memory where the variable resides. so the interpreter running into this unset() statement searches the reference table to find the pointer named $a to delete its name from the reference table. it doesn't find it, but it's ment to unset it anyway, why should be complained about it. in the next line the $a is not set, as u want it. mmmh nice as well that nobody told me direcly that I mixed set with given Excuse me? I told you as soon as I knew that's why you were getting it so wrong. ps.: great behavior, I think for less then 10% of the world population is english the native language, such a behavior prevents very good and smart programmers arround the world to share their knowledge. I actually think it's perfectly reasonable to expect people contributing to this mailing list to have a good grasp of the English language... at least enough not to make errors like the one you have here. I understand how rude it can appear but I think it's important that information resources such as this are as reliable as possible, and if that means you need to be a bit more careful about asserting your expertise when there's a chance that you've misunderstood the question. I see no difference between misunderstanding due to language issues and misunderstanding due to having not read the question correctly. They both have the same effect. Maybe I'm being too harsh. I'm sure you have a lot of knowledge to share, but if you want to participate in what is an English mailing list please be more careful in future. Now, on to my real problem with the way you answered the question. After your initial mistake you proceeded to, as far as I can tell, completely fabricate a reason for the behaviour you were seeing with absolutely nothing to back it up whatsoever. And then, despite being corrected you repeated it. That's what I really objected to - anyone can misunderstand a question, but filling in the blanks from thin air helps nobody. Ever.

Here's my take on it: I'm absolutely certain that I'm easily smart enough to be rich. Why aren't I? Because I've just never been that interested in making a lot of money. Of course, I can see the advantages of being rich, and of course, I'd like to be. But I've never placed that much importance on it. I'm much more interested in doing something I like (programming), running my own business (and not having to answer to a boss who's an idiot) and having a great marriage to a woman I can spend hours talking about nothing to.

There are some *very* lucky people out there who get away with doing and/or knowing very little, with minimal intelligence but who manage to get paid over-the-top amounts for it. In my experience they are the type of person for whom money is the goal. I hate that attitude and it says more about society in general than such an individual. For me money has never been a core driver in my life, mainly because I've been fortunate to usually have a job that pays well enough to provide me with everything I need, but so far I've never felt it was excessive. IMHO the richest person in the world is the one who would still do what they get paid for after they've won £100m on the lottery. Having a job you love so much that you can't imagine not doing it is the holy grail. I reckon I'm pretty close to that because I love my job (both current and new) and the only thing I would change if I could would be to own the company rather than work for it, but that would change little in my day-to-day activities.

I've worked in a number of organisations where the sales staff were treated like rock stars and the people who did the actual work were treated like commodities - easily replaced. I've also worked in (and now insist on only working for) organisations that recognise that building stuff is as important, if not more so than being able to sell it. When it comes to software, especially since the (and I really hate the term, but) Web 2.0 label took off it's become increasingly clear that a good product will sell itself through personal recommendations many times more successfully than a glossy ad campaign. It's also being recognised that a fair proportion of the public now object to being sold something by pretentious, over-confident, pushy salespeople, and it's fairly likely they'll be put off buying whatever their selling regardless of what it is. This, I think, is the source of the recent switch in focus from polished advertising to polished products. This switch coupled with the low cost of distributing software via the internet has created the perfect environment for small companies to create great products and compete effectively with traditional shrink-wrapped software publishers. And long may it continue. Better quality software is better for everyone, users and developers alike. Incidentally, I should say at this point that if PHP has one weakness in this brave new world its that the barrier to entry is far too low. It's just too easy to do it wrong and get away with it. Most languages specifically aimed at web development suffer from the same problem, but PHP seems to have special skills in this area. I've been recruiting for my replacement recently (drop me a note if you're interested in a lead developer role in a financially stable UK-based company) and as with every time I recruit PHP developers it scares me the number of people out there commanding decent salaries when they really don't know what

Re: [PHP] Re: unset() something that doesn't exist
php tigger is right i think. Because of Zend engine parse line by line.(I can't use English give expression to it with My Poor English). It mean that (What I think) unset function is right parse but error for is parameter. Tigger Display :Warning: Wrong parameter count for unset what is your think. But Developer want it backend compatibility that I guess. See http://us.php.net/manual/en/function.unset.php change logs 4.0.1 Added support for multiple arguments. 4.0.0 unset() became an expression. (In PHP 3, unset() would always return 1). 2009/8/25 tedd tedd.sperl...@gmail.com: At 2:31 PM +0100 8/25/09, Stuart wrote: Please don't reply directly unless you intend to pay me for my time. 2009/8/25 Ralph Deffke ralph_def...@yahoo.de: sorry but its about the top topic it say it never does an error if u dont give an argument I accept that your English is not great, but given that you should be a bit more careful.

To be fair tedd English is clearly not his main language and I can see how you could misunderstand the original question as he did. What I objected to was that he took what he interpreted as the question being asked, saw that it did in fact behave that way and then proceeded to completely fabricate an explanation as to why it does so when that explanation does little more than demonstrate that he clearly has no understanding of what's actually going on. I can't stand people who claim to know what they're talking about when they're really making it up as they go along. Actually, an explanation like that does do a lot more than demonstrate ignorance. It gives naive observers of this thread, now and in the future, incorrect information that they may potentially rely upon if nobody corrects it. That's why I'm wasting my time on this - I do it for the greater good. Hmm, maybe I just need a holiday... -Stuart -- http://stut.net/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Re: unset() something that doesn't exist
sorry I mixed 'set' with 'given' and if my mistake did prevent all the smarter guys to give u an answer I'm sorry too. I hope not to be too limited to give u an answer well, think about how PHP 5 works. $a e.g. is a REFENCE to some memory where the variable resides. so the interpreter running into this unset() statement searches the reference table to find the pointer named $a to delete its name from the reference table. it doesn't find it, but it's ment to unset it anyway, why should be complained about it. in the next line the $a is not set, as u want it. mmmh nice as well that nobody told me direcly that I mixed set with given ralph_def...@yahoo.de ps.: great behavior, I think for less then 10% of the world population is english the native language, such a behavior prevents very good and smart programmers arround the world to share their knowledge.
