Deep Dive into RavenDB webinars

Dec 08 2006

The most fun part in talking technology...

time to read 2 min | 305 words

I do a lot of communicating about technical stuff, sometimes with our own developer teams, sometimes with clients, and sometimes with just random dev groups that I get to meet (user groups, email, IM, etc).

Almost invariably, whenever I talk to them about the way they built their projects (I hate the word architecture), I got through the following stages:

This isn't how I would do this...
Oh, My God!
Why are you doing this??
Oh, I see.
Hm...
Just let me think about it a moment
So, what you are doing is actually XYZ beause of ABC.
Nice...

The best part of talking tech is that I keep learning so many new approachs to solve the same problems under different constraints.

Of course, there is another variant for the above scenario, Legacy code:

Bloody Hell! (someone please show me the exit, now).
I want the home address of the guy who wrote this file, oh, and a pair of thumb screws...
There goes the week/month/year...

That's why it is a good idea to compare the return value of `write` to the buffer size. "size_t" can be 32-bit on some system...

There's a reason we miss `write_exact` and `read_exact` from the standard library. In fact, I am surprised the chunk is actua...

kpvleeuwen, I agree, unfortunately I don't have anyone to ask off the top of my head. Thanks, I fixed the headers.
