Python Multiprocessing

A quick note-to-self on how to make the Python multiprocessing module work the way I'd like it to ...

GraphQL

I've been glancing sideways at GraphQL for a number of years after hearing it described and not fully understanding 'exactly' what it was or how to use it ...

Python

There's always version 2

Given the current state of affairs I've finally had a little time to site down and re-write PyNNDB with proper documentation, to proper coding standards, and using slightly more Pythonic patterns.

Oy! Pack it in!

Computers are never fast enough, Python is never fast enough, but there's always scope for improvement ...

Python

So, everyone should use JS eh?!

Over the last couple of years I've lost track of the number of people who've told me that Python is dead because eventually everyone will be using Javascript .. because it runs on the server AND in the browser. Although I've always considered that the argument has merit, Node's stability and

To replicate, or not to replicate

Often a very important question when designing your database and applications .. but what if it wasn't? Current / common database systems like MySQL, Postgres, MongoDB and so forth, all seem to have adopted a modern paradigm which involves disconnecting applications from the data they are intended to operate on, typically by

Python

OMG an ORM for NoSQL?!

My previous contract involved using SQLAlchemy with Postgres, neither product was something I'd spent much time on previously, so using them in anger was quite enlightening. I can sort of see why people like to use ORM's, especially if you're coming from a background where they are the norm (Java?

mongodb

If it walks like a Database ...

And crawls like a Database, then likely as not it's probably a modern Database. Just to be specific I've spent the last few years working with MongoDB, partly because it's a new-style NoSQL Database and is better for web work than SQL DB's, and partly because it interfaces really well

Python

Life in chains

Back in the 80's I was introduced to Unix pipes and was amazed by what could be accomplished by joining together a sequence of relatively simple commands. More recently I've come across a similar mechanism in jQuery for chaining together a list of selectors to produce a very complex operation

mongodb

Just how bad can it be?

Mongo has proven to be very useful in recent years, and the way in which it integrates with Python makes it an ideal storage tool for Python based projects. However, I've started to notice on projects that are sensitive to performance, it can be a little on the slow side.

iflexCron

Just to remind myself, I'm going to start posting useful microservice snippets so when I figure out how I'm going to add templates and libraries I have a stock of stuff to add. In this instance I've previously been calling CRON (the Unix tool) for batch processing, writing a stand-alone

Python

Test Driven Development

Interesting experience yesterday, was introduced to the concept of "Test Driven Development", it's a term I've heard banded about, but not something I've seen in action before. After an initial reaction revolving around "why?!" I think I've arrived at the conclusion that like all "new&

Countdown ...

Ok, today I started putting up some community stuff for iFlexStudio. I've just managed to get all the Ansible stuff working, so I can roll out an instance on Digital Ocean with minimal finger movement, now I'm back on the bug list before I do any more feature work. What

crossbar.io

For Example ...

So, Roger from the Crossbar forums suggested I write a blog post describing how to use my new IDE to build some of the Crossbar examples, sounded like a good idea. What could possibly go wrong?! Well, problem number one is the complete change in emphasis. The examples are designed

Python

Time to decorate ...

Ok, if you're not a Python programmer this might be irrelevant to you, unless of course it proves to be yet another reason why you should be ... maybe in preference some lesser scripting languages. (No flames please, I didn't mention PHP ...) In more recent times I've started to notice more

crossbar.io

Rise of the machines ...

Ok, maybe a little over-dramatic, but I've been working on this (off and on) for the last few years and yesterday I started to put a GUI / UI around what I now have .. it's going a little better than expected. IONMAN started out as a door-entry system, based on an

The perils of a dynamic data ...

Once upon a time, we used to have mainframes where everything was done in one place and the stuff user's could work with was delivered in ASCII to a green-screen terminal, and the only thing going down the wire was what the user was allowed to see. Then came Client-Server

Crossbar.io

I've just set up a demo of the work I've been doing on Crossbar with Microservices and SPA's, it's all available on Github Here, and there's currently a live demo running Here. Features of the demo Single HTTP load to initialise application All subsequent 'page' loads are via websockets All

linux

ProLinux Desktop 1.0 (alpha)

Finally managed to bin the remainder of debian-cd in favour of a build process written entirely in Python (338 lines at the moment) with no Make, Bash or Perl in sight. Runtime to produce an ISO image from cold is ~ 1m20s, presently running at a little over 1G. # time ./make_

python-apt

Breaking broken ...

Far be it from me to complain about free software (!) but after spending the last few weeks working with the debian-cd package I'm more than a little bit horrified. Is this really what people are using to generate install CD's ?! Ok, so it builds lots of different architectures, lots of

linux

What the APT?

I've been playing around with the debian-cd package recently for ProLinux, turns out the Debian build process is a little antiquated and written for the larger part in Perl. As a result (mainly of the latter), I'm in the process of re-writing the entire procedure in Python and have come

C

No, really, you don't have to C everything ...

As a programming language C is great for performance, flexibility, readability and endurance, but seriously, it's not the best tool for every job. If for example you need an intelligent web server to serve up to a few thousand requests per second of coded responses you might try to write
