Poor Prerequisites and Followup

Icon 3 Comments
As a recent college grad looking for that "first job", I'm amazed at the number of listings that require 'X' amount of years in a language as a bare minimum requirement. The loose correlation appears to be that the longer one has used a language, the better they are at it.

Why is that the predominant mentality? ...

What do passwords typically "require"?

  • Lower case letters
  • Upper case letters
  • Digits [numbers]
  • Symbols
  • A certain length

It's Getting Progressively Worse

An email I received earlier today:



Some thoughts:

The usual crap, misspelled words, poor grammar, etc... but I'm particularly fond of the FBI cyber crime department twist. It appears [you, the recipient] have been in contact with some nefarious people so we'll help you get some money; all you have to do is send us $260 after...

Right off the bat, I did not come up with this concept myself. I was inspired by @BenAlabaster. Rather then tweeting #FF people, I could make a single blog post which would allow for more robust descriptions of why one should follow my recommendations of individuals to follow in the twitterverse ...

Code "Guessing"

Icon 5 Comments
We've all done it. It's almost a rite of passage, but it needs to stop. Guessing at code means you've abandoned all paths of knowledge and logic and are now flailing hopelessly at some code.

There used to be a time, for all of us, where we'd start...

This is not a political post, so please return your underwear to the untwisted position.

Icon 14 Comments
Less then five minutes ago, the following was uttered on the forum:



WOAH!

Everyone, everywhere, this is not factual, but oddly enough, widely permeated. Yes C can be cryptic, yes C can be low level, but that does not, I repeat, does not, give one permission to write code that looks like something off of an ancient Egyptian wall....

Frequently Asked Programming Questions - Part I

Icon 1 Comments
We get a lot of programming questions here. They come in waves; they come in packs. The analytically minded among us have noticed patterns among threads (start/end of a semester, extra credit, AP tests, etc...). There are also a lot of "repeats": the exact same question, a variation on that question, or a permutation imposed by the giver...
