Alt-J – Greasemonkey script to replace Wingdings

Here’s a Greasemonkey script to get rid of those horrible “J” characters we see when an Outlook user tries to send you a smiley.

(Thanks to Abhinay Omkar’s “J for Smile” script which was the inspiration here.)

I don’t really use Greasemonkey but it seems that most people put their scripts on – however this seems to be a repository for Chinese spam and other garbage. So here it is:

// ==UserScript==
// @name        Alt J
// @namespace
// @description Replace J with smiley etc
// @include*
// @grant       none
// @version     1
// ==/UserScript==

function makeSmiley(sm)
        case "J":
        return "☺";
        case "K":
        return "😐";
        case "L":
        return "☹";
        return sm;

function makeSmileys(){

    var fonts = document.getElementsByTagName('font');
    for (var key in fonts)
        var font = fonts[key];
        if (font != null) 
            var face = font.face;
            if (face != null && face.indexOf('Wingdings') != -1)
                font.innerHTML = makeSmiley(font.innerHTML);

    var spans = document.getElementsByTagName('span');
    for (var key in spans)
        var span = spans[key];
        if (span != null) 
            var style =;
            if (style != null && style.indexOf('Wingdings') != -1)
                span.innerHTML = makeSmiley(span.innerHTML);

C stdio – disable buffering

Sometimes it’s useful to disable buffering for printf/fprintf etc. This is especially the case when you’re trying to debug a program and you’re not sure if it’s going to exit prematurely, before the output buffer gets flushed.

It’s a pain to stick fflush() after every fprintf. The proper way to do it is:

setbuf(stream, NULL);

The manpage assures us this is equivalent to the more verbose

setvbuf(stream, NULL, _IONBF, BUFSIZ);

Array equality in JavaScript – functional style

So it turns out there is no built-in test for array equality in JavaScript. There are some suggestions here on StackOverflow, but I wanted to see if there was a simple answer using Functional Javascript.

Here’s my attempt:

ArrayEq: function(a1,a2) {
    return reduce("x && y",true,map("x[0]==x[1]",zip(a1,a2)));

Reading from right to left, the zip transforms them into an array of pairs, then each pair is compared, and then the reduce applies the && operator to each boolean result in turn.

Quick random passwords

I’m sure there are lots of password generators out there, but a quick way of achieving this at the command line is something like

cat /dev/urandom | dd count=1 2> /dev/null | base64

Then copy and paste as much as you need. The result will be fairly unmemorable, but apart from OS login passwords which need to be typed, most logins can be automated, eg by using user:pass@host style URLs.

How do I store long strings with Firebird, NHibernate and NHibernate.Mapping.Attributes?

Yes, I know, it’s the hot question of the moment which everyone is asking.

Anyway, I figured that someone else might want to know this, since Firebird is a supported database for NHibernate, and the embedded version is very handy.

This is what the declaration for a member called “Detail” should look like (I think you can omit the “Name” attribute if you want):

[Property(0, Type="StringClob")]
[Column(1, Name="Detail", SqlType = "BLOB SUB_TYPE 1")]
public virtual string Detail { get; set; }

So the SqlType bit is Firebird-specific, and I don’t think it was very obviously documented anywhere in the Firebird docs. It feels a bit nasty to write code like this because it means I’m locked in to one database backend FOREVER.

For a fun bonus rant, the NHibernate page seems to be down at the moment. You can say what you want about Java, but the open-source tools and community are so much richer for Java than they are for C#. In fact, I’d say that C# is at around the Java 1.2 level on this basis.

Richard Stallman’s Rider

Thanks to The Register, whose story linked to an email which details RMS’ rider and requirements for making speeches in tedious detail.

Honestly, this stuff makes “a bowl of blue M&Ms” look trivial. We learn that he doesn’t like dogs, can’t sleep if the temperature is higher than 22°C, and that “I like some wines…but I don’t remember the names of wines I have liked”.

Even if I thought this guy was the messiah of free software (I am an avid emacs user), I don’t think I would want to host such a fussy and childish person.
