This one has us applying a simple algorithm to a list of strings to extract some characteristics of a string - specificially, whether a given string contains exactly two or three of any letter - then summing up how many each of these characteristics applies to the strings, and multiplying …
I haven’t posted here in two years. This site was meant to be a way for me to start writing something more than post random crap on Twitter. I’ve failed at that, but I’d like to try again.
Note
What’s written above was accurate when I …
Back in January, I picked up a Lenovo Miix 310 a while back to play with Windows. It was an interesting experience, but I really can’t see myself shifting my development over to Windows any time soon, so I figured I’d throw Xubuntu on it and see if …
The orthography of Esperanto is terrible. Not as bad as, say, English or French, but pretty bad. It needn’t have been this way, though, as it’s so very close to actually being good.
Many screeds against Esperanto orthography will point to its use of diacritics, but this is …
This has frustrated me for so long.
If you want to use checkboxes in a form in Django, the obvious choice is BooleanField. There are times it would be really useful to have the value attribute filled out, but by default, Django just checks for the presence of the field …
Some good friends of mine got married recently, and I helped out with the site for the wedding. One of the things that needed to be put up on the site was a poem. Now, just dropping the text of the poem into the page as-is would look weird; poems …
It’s almost like a rite of passage for a developer to write a monad tutorial.
Well, this isn’t a monad tutorial. This is simply an effort to put an end to some of the nonsense that leads to monad tutorials being written in the first place and all …
My git workflow for anything non-trivial is pretty straightforward, but a little different from what I’ve seen others describe. I’m almost certainly not the only person out there who uses this workflow, so I’m certainly not claiming any originality.
There seem to be two camps, both based …
It’s funny. When I started this, I didn’t think the first proper post here I’d make would be on Irish grammar. This assumes a certain basic knowledge of Irish, such as word order and basic vocabulary. Tweet at me with any feedback.
Like English, but unlike many …
One of the things I’ll be covering here will be languages.
I’m currently learning a number of languages, though I’m taking some more seriously than others. The ones I’m currently taking seriously, in order of importance, are:
I would actually like to be …
Can’t Hack is a blog. Those who know my might know that I already have a blog over at stereochro.me, but this is meant to be something a little different.
Over the years, I’ve began feeling somewhat burned out in general. There are so many things I …
Earlier this summer, I started brushing up on my French, and learning Spanish and Portuguese using Duolingo. More recently, I started learning some Dutch too for when I attend FOSDEM. Here are some resources I’m using to help me.
It’s long struck me as peculiar that package management isn’t more commonly built on top of union filesystems. I’m sure there’s probably somebody who’s had roughly similar ideas to the ones I’m about to put forward, but I’ve never came across them being …
I’ve been reviewing some SQL queries recently, and I’ve noticed some things that people do that lead to far from optimal performance. Here’s a few, and what people should be doing.
COUNT(*) vs. COUNT(col)At first blush, these may seem the same, but they actually mean …
One elementary error people make is using the type() function where isinstance() would be more appropriate1.
If you’re checking to see if an object has a certain type, you want isinstance() as it checks to see if the object passed in the first argument is of the type …
[Here’s something I knocked up for one of my co-workers who’s an experienced developer, but a Python neophyte. It may be useful to others.]
As in PHP, the global keyword in Python declares that any reference to a given variable name within the scope of a function or …
Ireland is a country of just over four million people, with a parliament consisting of 226 members in total, with 166 members in the the lower house and 60 in the upper, so for a nation of our size, we’ve a disproportionally high number of public representatives for a …
I did the minesweeper kata a few days back. It was a bit too easy, though it’s quite possible that this is more an artifact of how I approached it. Given that it’s a simple one, it might be an idea to see if I can take it …
I did the Harry Potter Kata earlier because I was feeling a little bored. Here’s the result. I use cents rather than euros as my unit of currency here.
I’d a start when I was thinking about how I’d solve the problem. I thought that being greedy …
