Expert Beginner Dev's Know They Know Everything
-
I worked with a person once who was having to parse XML. Person would scream every time the schema (we used DTDs) changed. Now, I would think screaming is normal because the schema should not change after development started (at least not much). So I kept my head down and ignored it. Well, this person screamed much worse and never stopped. The person would scream from one day to the next - even until the next schema change happened, at which time the person claimed the code had just started working again due to the previous change. One day this person left the company. A second person who was working with this person was now responsible for the code... The second person came to me and asked if it was right... I looked at the code and the first person was parsing the entire LARGE XML structure manually as a string. Nothing worked and it was bug ridden. I looked at the 2nd person funny, who never raised the alarm while working with the 1st person. Both had degrees from prestigious universities - but could not ask anyone else in the company how to parse XML. We were using MS products of course, which have built in libraries for doing such things. That is my XML story... Lesson 1... be humble and ask for help. Ten minutes of help could have saved weeks of screaming X| Lesson 2... if your employees scream too much... you should code review their work before it is too late :doh:

Expert Beginner's are developers who do not understand enough of the big picture to understand that they aren't actually experts.

I've never seen this explained so well before. I finally know the term (Expert Beginner) to use for the contractor I worked with at a large mortgage bank who knew that he knew everything. This guy had convinced a publisher to publish his book so he basically threw it on my manager's desk and my manager hired him. It was proof enough that he was a genius. At one point I asked the contractor a question about his XML parsing code that he had written as part of a larger project. Me: I see you seem to have written some functionality that manipulates the XML. Why didn't you just use the XML classes built into .NET? ExpertDev:I tried those classes but they weren't any good so I wrote my own. Me <slowly>: Umm... First of all, you've now created proprietary code that everyone throughout the company has to examine and understand just to interact with your section of code now. That's one problem. ExpertDev: Well, I'm telling you the Microsoft libraries are 5 times slower than my code. Me: So you're telling me that you wrote better code than the .NET team at Microsoft? ExpertDev: All I can tell you is that mine parses the XML 5 times faster. I have performance data. Me: Yes, you're right. It is 5 times faster than the .NET XML DOM parser. That's because the .NET one parses it into a structured object that is easy to manipulate. The problem is that in

I'm sure, that one who sees XML as a string will fall over escaped chars in an entity... Take some time to create the proper data and you will see miracles... :cool:

:thumbsup: A long time ago I worked for a guy that had written a book. He knew absolutely nothing. To make matters worse, his hair was thinning and someone had convinced him to, well, paint his scalp black under the hairline to make it look like he had more hair. You can guess how much respect he got. :)
Hair plugs are worse. Trust me. I had to train a technical bod from our New York distributer - good bloke, spoken to him on the phone loads of times. So he flew over and we meet for the product training ... And he had hair transplants. All the hair on his head was in little identical clumps, in absolutely straight rows and columns, and while you're talking to him your eyes are continually rising up, and up in fascinated horror to the regular field of - presumably - butt hair all over his head ... :laugh:
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

When the C# developer has tried Java he will still pooh-pooh it though :D Erik's blog on the expert beginner was in The Insider a while back. The problem is that the more you know the better you know what you don't know. That's why the good people are modest, while the people who know just a little bit shout the hardest.

Two great truths. Too bad the whole world doesn't know them better.

I replaced such an 'expert' who had written a book. He spent 3 months delivering sod all, so they got me in, and I delivered it in 2 weeks. Experts, fuck em. Oh, and then there was the USB expert. What a twat. Thought a transaction error was to do with the transaction translator needed to run full speed device on high speed hubs! He delivered shit for months till I lost patience and put my own code in the driver.

To be fair some of the Microsoft classes can be difficult to use. After a few months battling my way through problem with the configuration classes, I really regretted my decision to use those MS classes. In future, I might roll my own or find an alternative. My point being, is that we all will have bad experiences that influence our future decisions. In time, you may forget what those reasons were and just stick to the libraries and patterns you're familiar with. Arguing over performance was the wrong argument to have. You should have really dug into the statement 'weren't any good.

In Manager speak - "I'ts costing me a fortune for this guy, don't tell me he's no good'
The manager was also saying: "Look, it doesn't really matter, because by the time anyone finds out that it's not great code it won't matter because then those people will just have to deal with it anyways. But, if you make noise, upper level management will think something is wrong in my group and then they might start looking more closely at me and my life is good right now. And that's what matters...my life being easy."

This was a long time ago, before the internet and smartphones. But probably something like this: 1990's INFOMERCIAL HELL #19: Spray paint the bald away with GLH, by Ronco, of course! [^]
"...But the BABES are back!!" lol. That is one seriously awesome commercial. Thank you.

True story... When I was a system engineer with Sperry-UNIVAC back in the day, one of the account reps told us a story about an IT manager that he swore was true. A client IT director was complaining about the slowness of printing reports from one of our small mainframe machines. As most of these directors did not want to spend the monies to upgrade to the far faster printers, this particular account rep suggested that the director put the disk drive units on their third floor, the mainframe unit on the second and the printer on the first. This way the electrons would be going down and as a result, much faster to the printer. About a month later when the account rep visited the account for a regular checkup-call he found the director immersed in blue-prints for the reconstruction of the IT department. Asked what the director was doing he told the account rep that he had gotten permission to start rebuilding the IT areas to implement the account rep's previous month's suggestion for faster printing... Our profession is just littered with stories of such stupidity, which are more often than not completely true. The reason for this is that the quality of technical management in our field tends to be quite low despite all the hype about how they consistently try to hire the best and brightest. In short, most such management are irrational, incompetents who barely have the ability to reason beyond what the company expects of them. They in turn hire buffoons who the original poster of this thread described. Rational, technical personnel who understand this perpetuation of irrationality in our field slowly go insane over the many years we attempt to deal with such people in during our career. It is no wonder that our profession is such a mess?
