serve maps, DIY style
Dec 19th
in this week i had lows and downs. i realised once again why the open source community has such a long way to go still. i was tasked to put together a ‘demo-able’ map server with client.
after about two days of reading i noticed there might be much more to google maps than just a couple of javascript command called to place a marker. mapping, and most important, correct, standards based mapping is a beast.
and i will show you how to tame it how to make it more tame…
putting the ‘errrrrrr’ in erlang
Dec 10th
so for a while i’ve been trying to do a small something, anything in erlang. got myself pragmatic programming in erlang, setup yaws on my ubuntu machine and downloaded an erlang web framework called erlyweb that seemed to glow with potential.
so, its been about 2 weeks, my fascination with erlang was as short lived as a teenage holiday romance. the concurrent language which would probably topple all others if the overheads weren’t so much. erlang has a huge learning curve, don’t think just cause you dabble in a bit of ruby you will pick up this language in one go
i’m sure it will More >
lyme, a stack of scalability
Nov 25th
so last week i’ve been to a conference in good ol’ silicon valley -
a lot of focus on scalability and performance. that being said – i’ve decided to be proactive and try out a stack i’m totally unfamiliar with, but apparently with great potential.
lyme – linux, yaws, mysql, erlanglinux - the tried and tested platform, open-source, and where all good things start.
yaws - yet another web server written in erlang, supposedly outperforms apache with throughput and parallel sessions.
mysql – i’m just a big fan, what can i say
erlang - the language, created as a general purpose, concurrent language
so finally i got my lyme stack running More >
ip’s, geolocations and whatnot (demo)
Nov 11th
so i took some time and did an ip2location lookup demo which will tie in very nicely with my next big post. this i’ve used in conjunction with a spatial system (explained in my previous post) done with google maps and a bit of black magic.
this service was developed in my time at azapi – and they were so kind to host it for me
so have a look at how this feature can be used – in a visually stimulating way
- oh, one more thing – this demo will only work completely if your in South Africa – my geo-ip database is More >
