Is Continuous Delivery all about the nuts and bolts of CI? Infrastructure automation and the design of build pipelines? The biggest constraint to being able to incrementally roll out new features are oftentimes the problems in the design of the system itself. And this is often drowned in the CD conversation. To enable rapid, frequent release, it is essential to understand the kinds of constraints we should consider when evolving the archite..

The sidebar in Mutt is useful if you have multiple email accounts and want to switch between them quickly. It shows you each inbox with a number of unread emails. I have 6 Gmail accounts plugged into my Mutt and here is what I used to see. INBOX (1) INBOX INBOX (2) INBOX (1) INBOX (7) INBOX And I had to remember which one was which. Let’s say you have your mailboxes in ~/.mail. $ ls ~/.mail work home Create a directory called aliases..

One of the hardest ideas for developers to grasp in Codename One (or GUI programming in general) is the idea of a single event dispatch thread (EDT). The rules of using it and releasing it are sometimes complex and mistakes are very easy to make e.g.: Writing complex/slow code that blocks the EDT thus slowing the entire application Accessing Codename One widgets from a thread that isn’t the EDT. The problem is that both of these issues ..

How do move from releasing every few months, to weeks and then perhaps daily? Is “Fail fast, Learn fast” the way to get there? Enough of talk… I’d like to see how it really can be done? Please do join us for our Go User Group webinar (GUG) on Tue, Oct 30, 2012. This interactive (plenty of Q&A time) webinar will feature two 20-25 min presentations:

Hello fellow readers, I've been away of the social networking scene for a year, after obvious wrong events such as Facebook entering the stock market. This post is a reminder of those horrible, so called, online social networks. Social networks make people look stupid! On a personal level, I've been out for a year and I still feel the weird nausea arising when looking at people wasting their precious time on those networks; wandering, l..

Logos are a trap. Let me explain that statement: they are a place many startups get stuck. A logo is what identifies you. It's the symbol that takes up space in a customer's mind when they think about your company. There is no symbol that is more connected to your company than a logo. This traps entrepreneurs because it drives many of us to want the perfect logo. This is how I got Review Signal's logo created in 3 days from start to fin....

Redis is an advanced key-value store. Like memcached on steroids. Everything is in the RAM and you can theoretically reach 100 000 GET per second with Redis. My solution below will cache all the HTML output in Redis and display it without the need to load WordPress. A big thanks to Jeedo Aquino who have [...]

Let’s talk about compiler backends. C should be a portable language, and there is no need to rewrite the whole compiler if you want to port it to the new CPU architecture. Backend is a part of the compiler that generates low-level byte code. Compiler itself just calls backend functions. Good backend design makes the compiler highly portable. I wanted CUCU to be a portable compiler (actually, a cross-compiler). So, I decided to move backend ..

I recently set up a Mercurial server (Windows, Apache, ActiveDirectory and hgweb.wsgi). However, cloning our 1Gb repository took an hour or more and often failed. The only information in the Apache log was mod_wsgi (pid=1234: Exception occurred processing WSGI script 'C:/hg/hgweb/hgweb.wsgi' IOError: failed to write data The solution was to disable compression by adding the following lines to hgweb.config [server] preferuncompresse..

Both continuous delivery and devops have become mainstream, at least in terms of mindshare. As a result, a lot of vendors have jumped onto the bandwagon. Most products that have anything to do with deployment now try to associate themselves with devops and continuous delivery. In this webinar, Sriram will try to clear the air in a product independent manner. He will also cover common devops anti-patterns and explain the idea of infrastructu..

It continues to amaze me how bad Haskell is at processing strings. One of the reasons I wanted to learn Haskell was to be able to write short, dynamic-language-like programs that execute fast once compiled. Somehow rather, Haskell has failed to deliver on its promise of bare metal speed. I mostly write scripts and utilities meant to run on my machine—these scripts mostly process text. Read a file, parse it and spit something out. Exa....

Dear internets, I’m a sysadmin/architect, which means I spend a good amount of time coding in puppet and other languages. Puppet is a great tool, however the puppet community is a bit anal strict about their style policies. I can respect this because I understand how important uniformity is when many developers are sharing code. ( On a side note, I absolutely can’t stand using spaces for indentation, but that’s another story. Plea..

So far, we have defined language grammar and have written a lexer. In this part we will write a parser for our language. Before we start, we need some helper functions: int peek(char *s) { return (strcmp(tok, s) == 0); } int accept(char *s) { if (peek(s)) { readtok(); return 1; } return 0; } int expect(char *s) { if (accept(s) == 0) { error("Error: expected '%s'\n", s); } } peek() returns non-zero value if the next token is equal to the giv..

For those of you unable to attend JavaOne this year, you can check out the full video of our session here. You don’t actually see me but you can hear me talk and see the slides/demos since the feed from the projector was recorded. Apple wiped my iPad the day before with a stupid iOS 6 beta bug and my version of the demo had some bugs in it, but other than that I’m pretty happy with the presentation.

Drag the bookmarklet link below onto your bookmarks toolbar, then click it when you are on the OKC search page, and voilà, you will have the options for 5 and 10-mile searches. 10-mile radius will be selected, so just click "search" and you will have....

Let talk about the compilers. Have you ever thought of writing your own one? I will try to show you how simple it is. The first part will be pretty much theoretical, so keep patience. what we’re going to achieve? CUCU is a toy compiler for a toy language. I want it to be as close to ANSI C as possible, so that every valid CUCU program could be compiled with a C compiler without any errors.

We recently added Windows Phone support to Codename One, this allows you to build your applications as a Windows XAP application for installation on a Windows Phone device. Unfortunately of all the platforms we support (including J2ME and iOS) MS is the only company that chose not to allow standard OTA distribution so you will literally need a PC in order to install the application with a cable.

In my professional work, we have a system that utilizes __call and __callStatic for caching of certain method calls. We have been running into a problem where calling an undefined method via :: within the class itself will trigger __call rather than the expected __callStatic. The Problem The following code example illustrates the issue.
