Labour’s Rule Book

I have posted and try to maintain  the most recent copy of the Labour Party Rule Book  that I can find, this is also hidden in member’s net; this latter link requires a login and the search engines have difficulty in finding it.

I have also created a bit.ly short name for the LP’s version, bit.ly/uklabourrules17. This copy of the rules is the 2017 rules, presumably authorised by lab16. Hover over the links to see the tool tips.  Continue reading “Labour’s Rule Book”

Rendering New Age Video

While winding myself up to play NWN2, I started experimenting with image morphing software, to see if I could make a video of a Druid Shifter polymorphing into their werebear shape. Sadly I think I lost the pictures from the 1st attempt and so as I started the game I had another go. Anyway once created, there is the question of how to serve it on the web. This article documents the tools I used to create the video and the tools I used to host it on this page. Continue reading “Rendering New Age Video”

pump.io and microblogging

I returned to pump.io in Oct 2016 and again in May 2017 when I rebuilt the page deprecating aged content . The page had remained unchanged since I had to stop my 2015 experiments. In 2015 I’d got the server software working but had not made a usable solution for either micro blogging, nor for messaging. I hope that the pre-reqs remain  node.js, npm, a database server and ‘gm’. I assume that node.js forever remains desirable.

2016

Here are some links

I decided to install on a brand new U16 image and there have been some npm install problems. I have worked out how to run mongodb in a docker container.

On my 1st U16 build I was getting errors on the npm installs but after loads of sudo ( apt-get update ; apt-get upgrade ), the npm calls work, although with warnings in the case of forever. Now onto mongodb.

mongodb

This page describes how to install and start mongodb. Use apt-get to install, I amended the .conf file to invoke smallFiles, implemented the recommended service file mongod.service and used the service command to start and stop as tests.

In May 2017, a moved the smallfiles command from the conf file to the command line in the services file.

It is recommended to run mongod in a non-root user, and that is what the systemd service file mandates and the post install triggers set up the mongo users. The first time mongod is run it performs a db initialisation, if this is done as root, you will need to remove all the files from the database sub-directory before it will run as a non root user because the daemon cannot manipulate the files previously created as root. Doh! I need to check about smallFiles as the alternate way to do this is from the command line.

mongodb file systems require support for fsync. It will not work with vbox shared folders. There are also performance reasons for not using NFS. There may be some problems in using data volumes in Docker. I used this page to guide me in building the volume structures/regime.

I built an image, using the instructions here, I pushed it to my repo and start the image first time using the following code,

$ docker run -p 27017:27017 --name mongodb-1 -d dfl1955/mongodb --smallfiles

npm & pump.io

Install via apt-get install nodejs npm using apt-get, for ubuntu symbolically link /usr/bin/nodejs to /usr/bin/node.

$ ln /usr/bin/nodejs /usr/bin/node

Install graphicksmagaick using apt-get, I originally did this using npm.

I have used the manual install route, so mkdir or

$ cd /opt/local/
$ git clone https://github.com/e14n/pump.io.git
$ cd pump.io 
$ npm install -g
$ npm test -g

and then

$ npm install -g databank-mongodb

make the jason config file, include the “serverUser” parameter and then make the user, this lives by default in /etc/pumpio.conf.json, then if you use the dafault loging location, you need to make /var/log/pump but first you need the user

$ useradd pump

then

sudo mkdir /var/log/pump
sudo chown pump:pump pump

Because of vbox, I installed and started samba & mongod obviously.

I made the pumpio config file

{
    "driver":  "mongodb",
    "params":  {"hostname": "localhost"},
    "hostname": "davevbu16c",
    "secret":  "ruislip",
    "noweb":  false,
    "site":  "Awesome Sauce",
    "owner":  "Dave Levy",
    "ownerURL":  "http://davelevy.info/",
    "port":  80,
    "address":  "0.0.0.0",
    "nologger":  false,
    "logfile": "/var/log/pump/pumpio.log",
    "serverUser":  "pump",
# don't want uploaddir anymore
    "uploaddir": "/var/local/pump.io/uploads",
    "debugClient": false,
    "firehose": "ofirehose.example"
}

Using the default port caused errors, so I transformed the listener port to 80.

2015

I have decided to give pump.io a whirl given the constraints of using other’s micro blogging services products. I last used this when it was laconica. The database server must have a databank client interface which they say means mongodb, couchdb or redis. They recommend mongo as the best default, should be fun.

 

On Ubuntu, one needs to make a link command to provide the alias of node to /usr/bin/nodejs. See more from Stackoverflow.

Installing forever, this is another node.js package and needs to be installed using npm. See also this article at exratione.com, and this article at Github. forever is needed to set some of the environment, and the use of the -a & -l flags are significant, or more accurately, the -l flag takes an argument, which is the first string after the flag. i.e. -l -a ${filename} doesn’t work. This has been bugged here…

https://github.com/foreverjs/forever

Important commands include, forever start application and forever –help. NB Global installations using npm make links in /usr/local/bin

My notes on packages and parameters have been moved to a comment, dated 2nd May 2017.

I have written a start/stop script. Wonder if anyone else will find it useful. (Probably not, its LSB compliant.)

To solve the problems related to pump.io itself I need to set the logging on. This will need prettyprint, see this and this. Looks like python will be helpful.

This might be best encapsulated using Docker.

NWN2 the official campaign

Here are my notes for the first run through. I am playing a barbarian which I will switch to druid after a time to get the Dire Bear shape shift. I am inspired by Lux the Barbarian from the film, D&D II and the Epic Guilds Berserker build, which I document here. This build may be weaker than optimum in the social skills for the Official Campaign. Also, I am not a fan of crafting and its possible I should have spent more skill points on one of the crafting skills for this run, some tests are against crafting and you might want to make some armour, weapons and magic items. Late research suggests that this is important and effective. I started to play the game in 2015, nine years after its release; the community is now pretty weak and I am unsure how useful it’ll be but it clearly remains a development platform.

E-Voting, some new technology

I have written a lot recently about how building e-voting systems is hard but here are two initiatives that try and address this issue. I need to read about them in more detail, but the first uses the blockchain, it would seem bitcoin’s blockchain, while I am less clear on the Liquid Feedback’s architecture and hence it’s security. Continue reading “E-Voting, some new technology”

Nulis

I have implemented the Nulis theme on the wiki, which is apparent if you visit the site using a desktop or other large screen device. It still uses wptouch for smaller screens. I have turned off wptouch for this theme. It seems good for my android systems. The rest of this article talks about anchor tags, the header image and additional toolbar buttons.
