The Evils of the For Loop 
(unknown author) via Shades of Gray on Thu, 08 Jan. 2009
Shared by jana4u
me prijde "for" v kodu lepe citelne nez ".each", ale asi je to otazka zvyku
I've never liked the for…in loop in Ruby. I cringe every time I see it in examples (Rails seems to put it in views a lot) and I tend to switch it to an each() call. It really bugs me.
That's mostly just my gut reaction, but if I had t

Top Ten Attributes of Good Clients
Obie Fernandez via Obie Fernandez on Thu, 08 Jan. 2009
The following attributes are arranged in countdown-style, to denote relative importance to me. I'm the first to admit that it's a subjective and incomplete list. Also, to go beyond "good" and be considered a "great" client, they would have to possess almost all of these attributes and more. No single attribute can redeem an otherwise "bad" client by itself, and many of the attributes on this li

Mr. Moore gets to punt on sharding

Shared by Mahesh CR
"No use preempting the technological progress of tomorrow" Pragmatic software product engineering...
Sharding is a database technique where you break up a big database into many smaller ones. Instead of having 1 million customers on a single, big iron machine, you perhaps have 100,000 customers on 10 different, smaller machines.

The Cost of Net Negative Producing Programmers
blogger@jayfields.com (Jay Fie via Jay Fields' Thoughts on Tue, 06 Jan. 2009
It's common to compare ourselves to doctors, lawyers, and other highly-paid professionals. Unfortunately, almost every comparison breaks down dramatically, very quickly.When doctors screw up (massively) they get sued. When (permanently employed) programmers screw up they get let-go, and they go find a new job, usually with more responsibility and a pay raise. There are no ramifications for

Modifying ActiveRecord fields in place
Ethan Vizitei via CodeClimber on Tue, 06 Jan. 2009
So here's a "gotcha" for Rails that had me chasing my tail for a few minutes today. Imagine that you have a model object that is storing a string that is encoded to represent a large amount of data in a small amount of space. For instance, let's say you have a calendar item that is using a string that is 31 characters long to represent the state of each day in the month (this is purely h

Successful Products Are Discovered, Not Invented
Adam Wiggins via a tornado of razorblades on Mon, 05 Jan. 2009
Successful companies rarely achieve their success on their first idea, says Jason Cohen. Instead, your initial idea causes you to get something out into the marketplace, from which you can discover a truly good idea:
Here's a newsflash: Your idea probably sucks, and it doesn't matter because

Ruby on Rails Tutorials
(unknown author) via Ruby Pond on Mon, 05 Jan. 2009
There has been a few occasions over the previous months when various people I meet have asked me to point them in the right direction to get started with ruby on rails. I remember when I started, it was a pretty easy question to answer… everyone just got pointed in the general direction of why_’s poignant guide, the pickaxe book, and agile web development with rails. But things have come a

Happy New Year

My first post on this blog happened in January 2008. At that time, I figured I'd be doing this for a couple months, and then move on to something else. Instead it's turned into something I truly have enjoyed, as I've gotten all kinds of valuable feedback and advice from readers. As a final post of the year (before I go find some eggnog and an X-Box party), I just wanted to thank everybody who t

Allowing custom CSS in your app
Courtenay via caboose - blog.caboo.se Home on Wed, 31 Dec. 2008
There are a number of good reasons why you don't want your users providing their own CSS (for example, when theming their site). These are: taste (see: myspace) and security.
The former is pretty much your users' problem. The pages don't have to look terrible -- and in fact Myspace charges a LOT of money to do those custom movie or band pages (it's part of the service when you buy the
