  A plugin to update last_error in Delayed Job

delayed_job is a process based asynchronous task processing gem which can be ran at background. It will fork the specified number of processes to execute the tasks asynchronously. The task status is usually stored in the database so that it can be easily integrated into a Rails application where asynchronous job execution is desired. Normally when a job fails to execute or error occurs, it would save the error into the database with the column last_error. Ideally all these will be handled b...

  Making Sites Shine with @font-face

Like many of my web designer brethren, I’m a bit of a typographic geek. And like many web designers, I’ve been frustrated (to say the least) about the historical state of web typography.At first, we were limited to a common, but very small set of “web safe” fonts. Anything beyond those fonts, we had to rely on images. Images for text not only meant we had to create and maintain dozens (if not hundreds) of images, but it introduced accessibility issue...

  Parallel Javascript

Lately the ideas for a parallel, shared memory JavaScript have begun to take shape. I’ve been discussing with various JavaScript luminaries and it seems like a design is starting to emerge. This post serves as a documentation of the basic ideas; I’m sure the details will change as we go along. User Model The model is that a JavaScript worker (the “parent”) may spawn a number of child tasks (the “children”). The parent is suspended while the children exe...

  On Erlang's Syntax

I first planned to release this text as an appendix entry for Learn You Some Erlang, but considering this feels more like editorial content and not exactly something for a reference text, I decided it would fit better as a blog post. Many newcomers to Erlang manage to understand the syntax and program around it without ever getting used to it. I've read and heard many complaints regarding the syntax and the 'ant turd tokens' (a subjectively funny way to refer to ,, ; and .), how annoying...

  Why, oh WHY, do those #?@! nutheads use vi?

Yes, even if you can't believe it, there are a lot fans of the 30-years-old vi editor (or its more recent, just-15-years-old, best clone & great improvement, vim). No, they are not dinosaurs who don't want to catch up with the times - the community of vi users just keeps growing: myself, I only got started 2 years ago (after over 10 years of being a professional programmer). Friends of mine are converting today. Heck, most vi users were not even born when...

  Code reviews in the 21st Century

There's an old adage that goes something like: 'Do not talk about religion or politics'.  Why?  Because these subjects are full of strong opinions but are thin on objective answers.   One person's certainty is another person's skepticism; someone else's common sense just appears as an a prior bias to those who see matters differently.  Sadly,  conversing these controversial subjects can generate more heat than light.   All too often people can get s...

  The Problem With Client-Side Analytics

Client-side analytics is broken. The numbers produced by it are trivially spoofable by competitors and nefarious characters. Most websites use client-side analytics of one type or another and the only way to get numbers you can trust is to compare numbers from multiple providers and to take an average of the closest two.This post highlights the problem and proposes a partial solution that substantially mitigates the issues with minimal effort. Our proposed solution is simply to include a digital...

  Cybersecurity | The New Dangers That Lurk Online and Their Solutions

(Image source: Pexels) Data is one of the most important things to us. While robbers that steal valuables like laptops, phones, or money are still a threat, cybercrimes are also more dangerous than ever. That’s because your data is far more valuable than you might think. Companies benefit from users’ data by applying it for their indexing, marketing, and accumulation needs. They actively use this information to sell you more products. Have you ever visited Amazon and instantly got a ...

  Glass Button in Photoshop

These days glass buttons seem to be very popular. You can find glass buttons in Windows Vista and all around the Web. Other popular buttons are metallic and plastic buttons.
