  1. Effective Value Delivery

    In Blog.

    Some time ago, as part of trying to help a core line-of-business system team improve their effectiveness, we brought Driven Software in to provide expert guidance. Driven (for short) are experts in assisting teams and organisations in streamlining how they manage their development work, or, as they would probably put …

  2. Shoutout to 2?xml2?

    Published: Fri 11 August 2017

    In Blog.

    I'd be remiss in not dedicating a blog post to this handy little utility, designed to allow Unix-heads to extend their honed command-line fu to XML. Let's demonstrate with a small example:

    $ echo "/root/=something in here" | 2xml
    <root>something in here</root>
    

    2xml takes line-oriented hierarchical data and converts …

    HTML Layout is Pain

    I’m the first to admit to my being an HTML-dunce. Over time, there’s been the odd need to get my hands dirty with HTML and/or CSS, but it was generally always fairly short-lived and things have progressed so unbelievably far since the late …

    Strings in Ruby are a little different from those in the Python or .NET world. Whilst the latter are immutable, the former aren't. I remember in the days in-which the .NET Dynamic Language Runtime was receiving a lot of attention, the issue of how IronRuby strings would be reconciled with …

    I’ve had this idea knocking around in my head for a while now; how to get everything to be “keyboard-driven”. Ultimately one needs to draw a picture or two, but that invariably involves the mouse, and with the mouse comes the imprecise. There’s something satisfying about knowing that …

    A prime number is a number greater that one which can be evenly divided only by one and itself. For instance, we can divide 3 by 2 and we’d get 1.5, but that wouldn’t be even. We can divide 3 by 3 and get 1; that’s …

    As a follow-on from a previous article I wrote on revisiting the oft-cited FizzBuzz program, a colleague pointed me to an interesting site where one can get to see FizzBuzz written in a whole bunch of different languages, namely: “Rosetta Code”. Rosetta Code describes itself as a “programming chrestomathy” site …

    One thing that I don't think is going to ever change in this domain is the fact that no matter how much you know, there's always something new to learn. Going back to basics every now-and-again is worthwhile, no matter how much of a seasoned player you may think you …

  9. Ruby: Nil Aint Nothing

    Published: Sat 29 July 2017
    By EWS

    In Blog.

    A kind-of universal “truth” that one becomes accustomed to as a programmer is that null aka NULL aka None means “nothing”:

    #include <stdio.h>
    
    void main(int na, char** args) {
         printf("The value of NULL: %p\n", NULL);
    }
    
    $ cc test.c && ./a.out
    The value of NULL: (nil)
    
    $ csharp

  10. A Grave Situation

    In Blog.

    Being ever-so-slightly “OCD touched”, the fact that using quotes in my standard Vim setup doesn't result in them automatically being “smart-quoted” has been a buzzing background noise for some time now. For all RMS's perennial reminders of the evil of proprietary software, it's like the most compelling of vices, you …

    As I mentioned in a previous post, I'm going through a sort-of programming renewal. I've never had a proper opportunity to get my hands dirty with the language of the web (is “web” even a term that people use anymore?), that is HTML/CSS (and, of course, Javascript, although even …

    I consider myself to be lucky to have been introduced to computers at a young age. I forget now exactly when it was, but I certainly remember the first "taste" I had for computers and programming. It involved a Hewlett-Packard 85 and Hewlett Packard Series 80 BASIC. I was hooked …

  13. Quick-and-dirty regular expressions with Runter

    By EWS

    In Blog.

    Parts 1 and 2 of a series about Regex discoverability in .NET led me to write a very small utility for "quick-and-dirty" regular expression matching (that is, of the same level of quick-and-dirtiness as sed or awk).

    Introducing Runter:

    There's only one thing worse than setting development screening tests and having to mark them, and that is being required to sit a screening test yourself which happens to contain a typical question that you yourself set in a past test. Well... I guess that should be a good thing …

    For some time now, I've had a sort of a mid-life-crisis-induced fascination with all things entrepenurial and consequently now spend an appreciable amount of driving time listening to podcasts in that vein. One of them is the excellent Get Altitude podcast by Eben Pagan. Eben is clearly a wickedly smart …

    For my sins, I have to assess three candidate software product suppliers in respect of just how good they are at what they do. In fairness, I only have myself to blame since I was the one who suggested doing such a due-diligence.

    I attended the Driven Software Unconference a few weeks ago which was structured more-or-less according to an Open Space model. One of the less-common technology-focussed topics of discussion was "Vim Tips and Tricks".

    Unfortunately "Vim Tips and Tricks" quickly degenerated to an Emacs versus Vim advocacy face-off (as tends to …
