I should really learn systemd

As I slowly upgrade all my machines to Debian 8.0 (jessie) they’re all ending up with systemd. That’s fine; my laptop has been running it since it went into testing whenever it was. Mostly I haven’t had to care, but I’m dimly aware that it has a lot of bits I should learn about to make best use of it.

Today I discovered systemctl is-system-running. Which I’m not sure why I’d use it, but when I ran it it responded with degraded. That’s not right, thought I. How do I figure out what’s wrong? systemctl --state=failed turned out to be the answer.

# systemctl --state=failed
  UNIT                         LOAD   ACTIVE SUB    DESCRIPTION
● systemd-modules-load.service loaded failed failed Load Kernel Modules

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.

1 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.

Ok, so it’s failed to load some kernel modules. What’s it trying to load? systemctl status -l systemd-modules-load.service led me to /lib/systemd/systemd-modules-load which complained about various printer modules not being able to be loaded. Turned out this was because CUPS had dropped them into /etc/modules-load.d/cups-filters.conf on upgrade, and as I don’t have a parallel printer I hadn’t compiled up those modules. One of my other machines had also had an issue with starting up filesystem quotas (I think because there’d been some filesystems that hadn’t mounted properly on boot - my fault rather than systemd). Fixed that up and then systemctl is-system-running started returning a nice clean running.

Now this is probably something that was silently failing back under sysvinit, but of course nothing was tracking that other than some output on boot up. So I feel that I’ve learnt something minor about systemd that actually helped me cleanup my system, and sets me in better stead for when something important fails.

Stepping down from SPI

I was first elected to the Software in the Public Interest board back in 2009. I was re-elected in 2012. This July I am up for re-election again. For a variety of reasons I’ve decided not to stand; mostly a combination of the fact that I think 2 terms (6 years) is enough in a single stretch and an inability to devote as much time to the organization as I’d like. I mentioned this at the May board meeting. I’m planning to stay involved where I can.

My main reason for posting this here is to cause people to think about whether they might want to stand for the board. Nominations open on July 1st and run until July 13th. The main thing you need to absolutely commit to is being able to attend the monthly board meeting, which is held on IRC at 20:30 UTC on the second Thursday of the month. They tend to last at most 30 minutes. Of course there’s a variety of tasks that happen in the background, such as answering queries from prospective associated projects or discussing ongoing matters on the membership or board lists depending on circumstances.

It’s my firm belief that SPI do some very important work for the Free software community. Few people realise the wide variety of associated projects. SPI offload the boring admin bits around accepting donations and managing project assets (be those machines, domains, trademarks or whatever), leaving those projects able to concentrate on the actual technical side of things. Most project members don’t realise the involvement of SPI, and that’s largely a good thing as it indicates the system is working. However it also means that there can sometimes be a lack of people wanting to stand at election time, and an absence of diversity amongst the candidates.

I’m happy to answer questions of anyone who might consider standing for the board; #spi on irc.oftc.net is a good place to ask them - I am there as Noodles.

Andy and Teddy are waving goodbye

In summary, I'm starting to wonder if Google have a time machine. Go seems to have nicely predicted several worries and trends since its announcement: Docker, Heartbleed, and social coding.

what is wrong with this sentence?

Yesterday the new Government published a press release about the forthcoming first meeting of the new National Security Council (NSC). That meeting was due to discuss the Tory administration’s plans for a new Counter-Extremism Bill. The press release includes the following extraordinary stement which is attributed to the Prime Minister:

“For too long, we have been a passively tolerant society, saying to our citizens: as long as you obey the law, we will leave you alone. “

Forgive me, but what exactly is wrong with that view? Personally I think it admirable that we live in a tolerant society (“passive” or not). Certainly I believe that tolerance of difference, tolerance of free speech, tolerance of the right to hold divergent opinion, and to voice that opinion is to be cherished and lauded. And is it not right and proper that a Government should indeed “leave alone” any and all of its citizens who are obeying the law?

Clearly, however, our Prime Minster disagrees with me and believes that a tolerant society is not what we really need in the UK because the press release continues:

“This government will conclusively turn the page on this failed approach. “

If tolerance is a “failed approach”, what are we likely to see in its place?

Recorrecting Past Mistakes: Window Borders and Edges

A while ago, I switched from tritium to herbstluftwm. In general, it’s been a good move, benefitting from active development and greater stability, even if I do slightly mourn the move from python scripting to a shell client.

One thing that was annoying me was that throwing the pointer into an edge didn’t find anything clickable. Window borders may be pretty, but they’re a pretty poor choice as the thing that you can locate most easily, the thing that is on the screen edge.

It finally annoyed me enough to find the culprit. The .config/herbstluftwm/autostart file said “hc pad 0 26″ (to keep enough space for the panel at the top edge) and changing that to “hc pad 0 -8 -7 26 -7″ and reconfiguring the panel to be on the bottom (where fewer windows have useful controls) means that throwing the pointer at the top or the sides now usually finds something useful like a scrollbar or a menu.

I wonder if this is a useful enough improvement that I should report it as an enhancement bug.

Building a componentised application

Without going into any of the details, it's a web application with a front end written using Ember and various services that it calls out to, written using whatever seems appropriate per service.

At the outset of the project, we decided we would bite the bullet and build for Docker from the outset. This meant we would get to avoid the usual dependency and developer environment setup nightmares.

The problem

What we quickly realised as we started to put the bare bones of a few of the services in place, was that we had three seemingly conflicting goals for each component and for the application as a whole.

  1. Build images that can be deployed in production.

  2. Allow developers to run services locally.

  3. Provide a means for running unit tests (both by developers and our CI server).

So here's what we've ended up with:

The solution

Or: docker-compose to the rescue

Folder structure

Here's what the project layout looks like:

Project
|
+-docker-compose.yml
|
+-Service 1
| |
| +-Dockerfile
| |
| +-docker.compose.yml
| |
| +-<other files>
|
+-Service 2
  |
  |
  +-Dockerfile
  |
  +-docker.compose.yml
  |
  +-<other files>

Building for production

This is the easy bit and is where we started first. The Dockerfile for each service was designed to run everything with the defaults. Usually, this is something simple like:

FROM python:3-onbuild
CMD ["python", "main.py"]

Our CI server can easily take these, produce images, and push them to the registry.

Allowing developers to run services locally

This is slightly harder. In general, each service wants to do something slightly different when being run for development; e.g. automatically restarting when code changes. Additionally, we don't want to have to rebuild an image every time we make a code change. This is where docker-compose comes in handy.

The docker-compose.yml at the root of the project folder looks like this:

service1:
    build: Service 1
    environment:
        ENV: dev
    volumes:
        - Service 1:/usr/src/app
    links:
        - service2
        - db
    ports:
        - 8001:8000

service2:
    build: Service2
    environment:
        ENV: dev
    volumes:
        - Service 2:/usr/src/app
    links:
        - service1
        - db
    ports:
        - 8002:8000

db:
    image: mongo

This gives us several features right away:

Running the tests

This was the trickiest part to get right. Some services have dependencies on other things even just to get unit tests running. For example, Eve is a huge pain to get running with a fake database so it's much easier to just link it to a temporary "real" database.

Additionally, we didn't want to mess with the idea that the images should run production services by default but also didn't want to require folks to need to churn out complicated docker invocations like docker run --rm -v $(pwd):/usr/src/app --link db:db service1 python -m unittest just to run the test suite after coding up some new features.

So, it was docker-compose to the rescue again :)

Each service has a docker-compose.yml that looks something like:

tests:
    build: .
    command: python -m unittest
    volumes:
        - .:/usr/src/app
    links:
        - db

db:
    image: mongo

Which sets up any dependencies needed just for the tests, mounts the local source in the container, and runs the desired command for running the tests.

So, a developer (or the CI box) can run the unit tests with:

docker-compose run tests

Kimchi Trial 1 - Part 3 - Kimchiguk

Earlier this week I allowed some of my colleagues at work to try the Kimchi and one of them (James) liked it enough to ask for a tub of it just for himself. Being a lovely person I obliged.

My darling Rob decided that what he really wanted was Kimchiguk or Kimchijijae. Being both wonderful and lacking in ingredients, I set to do achieving something.

I read a few recipes, worked out that I lacked critical ingredients and so set about simulating Kimchiguk. I grabbed two and a bit cupfuls of kimchi from the box in the fridge, chopped it up more finely, popped it into a pot along with about a pound of cubed pork belly, two teaspoons of hot pepper flakes, two teaspoons of sugar, and two teaspoons of cornflour. I then topped that off with five cups of water, mixed it up, brought it to the boil and simmered it for 30 minutes. Then I cubed some tofu, popped that in and simmered it for another 10 minutes while some rice cooked. Served in a bowl over rice, my approximation of Kimchiguk turned out pretty well. (Note it fed both of us and there was a serving left over.)

Kimchiguk - Kimchi soup

With a do-over, I'd try harder to get pork shoulder (belly is quite fatty) and given the option I'd wait until I had hot pepper paste because the malty fermented sweetness of hot pepper paste is pretty much impossible to emulate otherwise.

Kimchi Trial 1 - Part 2

Last night we tried the small amount of 'fresh kimchi' from my epic kimchi making trial.

I marinaded some beef strips in a blended paste of onion, garlic, ginger, and sesame oil for a few hours before frying that up, and serving on rice with stir-fried carrots, leek and spring onion. A little fresh kimchi on the side for flavour.

Delicious dinner

I think the Kimchi was a success. Dearest Rob said that it tasted of Kimchi. The flavours were not very well combined and quite clearly underdeveloped, and the pepper flakes were still a little hard. I expect this to resolve over the next few days as it begins to ferment.

All in all, experiment going well, expect part 3 when I know how it tastes after fermentation begins.

back on topic

Theresa May hasn’t wasted any time. The Independent reports today that Ms May (Home Secretary in the coalition administration) has said that the new Tory administration will bring the Draft Communications Data Bill, previously blocked by the Liberal Democrats, back to the House of Commons with the intention of getting it passed into law. As the Independent also reports, dear Dave, who is let us say, technically challenged, has in the past expressed the view that no form of communication should be unreadable by the Goverment. This implies severe restrictions on all forms of encryption.

Given that the Tories now have the majority they lacked in the last administration, it is clear that they will see themselves free to attack the kind of liberties I, and millions like me enjoy and cherish. The Open Rights Group maintain a wiki devoted to the relevant points of each political party’s manifesto devoted to surveillance or other possible attacks on privacy. As they point out, the Tory party is committed to:

There are, of course, huge practical and technical difficulties in implementing much of what the Tories wish to do (consider for example the idiocy of attempting to outlaw VPN technology) but that won’t stop them trying. Indeed, some of the technical difficulties may cause the new administration to bring in mechanisms to get around those problems. An obvious example would be the requirement for key escrow for anyone wishing to use encryption.

Excuse me if I find that unacceptable. Time to encrypt much, much more of my everyday activity from now on.

Pinned Apps – An App Model for the Web

(re-posted from a page I created on the Mozilla wiki on 17th December 2014)

Problem Statement

The per-OS app store model has resulted in a market where a small number of OS companies have a large amount of control, limiting choice for users and app developers. In order to get things done on mobile devices users are restricted to using apps from a single app store which have to be downloaded and installed on a compatible device in order to be useful.

Design Concept

Concept Overview

The idea of pinned apps is to turn the apps model on its head by making apps something you discover simply by searching and browsing the web. Web apps do not have to be installed in order to be useful, “pinning” is an optional step where the user can choose to split an app off from the rest of the web to persist it on their device and use it separately from the browser.

Pinned_apps_overview

”If you think of the current app store experience as consumers going to a grocery store to buy packaged goods off a shelf, the web is more like a hunter-gatherer exploring a forest and discovering new tools and supplies along their journey.”

App Discovery

A Web App Manifest linked from a web page says “I am part of a web app you can use separately from the browser”. Users can discover web apps simply by searching or browsing the web, and use them instantly without needing to install them first.

Pinned_apps_discovery

”App discovery could be less like shopping, and more like discovering a new piece of inventory while exploring a new level in a computer game.”

App Pinning

If the user finds a web app useful they can choose to split it off from the rest of the web to persist it on their device and use it separately from the browser. Pinned apps can provide a more app-like experience for that part of the web with no browser chrome and get their own icon on the homescreen.

Pinned_apps_pinning

”For the user pinning apps becomes like collecting pin badges for all their favourite apps, rather than cluttering their device with apps from an app store that they tried once but turned out not to be useful.”

Deep Linking

Once a pinned app is registered as managing its own part of the web (defined by URL scope), any time the user navigates to a URL within that scope, it will open in the app. This allows deep linking to a particular page inside an app and seamlessly linking from one app to another.

Pinned_apps_linking

”The browser is like a catch-all app for pages which don’t belong to a particular pinned app.”

Going Offline

Pinning an app could download its contents to the device to make it work offline, by registering a Service Worker for the app’s URL scope.

Pinned_apps_offline

”Pinned apps take pinned tabs to the next level by actually persisting an app on the device. An app pin is like an anchor point to tether a collection of web pages to a device.”

Multiple Pages

A web app is a collection of web pages dedicated to a particular task. You should be able to have multiple pages of the app open at the same time. Each app could be represented in the task manager as a collection of sheets, pinned together by the app.

Pinned_app_pages

”Exploding apps out into multiple sheets could really differentiate the Firefox OS user experience from all other mobile app platforms which are limited to one window per app.”

Travel Guide

Even in a world without app stores there would still be a need for a curated collection of content. The Marketplace could become less of a grocery store, and more of a crowdsourced travel guide for the web.

Pinned_apps_guide

”If a user discovers an app which isn’t yet included in the guide, they could be given the opportunity to submit it. The guide could be curated by the community with descriptions, ratings and tags.”

3 Questions

Pinnged_apps_pinned

What value (the importance, worth or usefulness of something) does your idea deliver?

The pinned apps concept makes web apps instantly useful by making “installation” optional. It frees users from being tied to a single app store and gives them more choice and control. It makes apps searchable and discoverable like the rest of the web and gives developers the freedom of where to host their apps and how to monetise them. It allows Mozilla to grow a catalogue of apps so large and diverse that no walled garden can compete, by leveraging its user base to discover the apps and its community to curate them.

What technological advantage will your idea deliver and why is this important?

Pinned apps would be implemented with emerging web standards like Web App Manifests and Service Workers which add new layers of functionality to the web to make it a compelling platform for mobile apps. Not just for Firefox OS, but for any user agent which implements the standards.

Why would someone invest time or pay money for this idea?

Users would benefit from a unique new web experience whilst also freeing themselves from vendor lock-in. App developers can reduce their development costs by creating one searchable and discoverable web app for multiple platforms. For Mozilla, pinned apps could leverage the unique properties of the web to differentiate Firefox OS in a way that is difficult for incumbents to follow.

Implementation

Web App Manifest

A manifest is linked from a web page with a link relation:

  <link rel=”manifest” href=”/manifest.json”>

A manifest can specify an app name, icon, display mode and orientation:

 {
   "name": "GMail"
   "icons": {...},
   "display": "standalone",
   "orientation": “portrait”,
   ...
 }

There is a proposal for a manifest to be able to specify an app scope:

 {
   ...
   "scope": "/"
   ...
 }

Service Worker

There is also a proposal to be able to reference a Service Worker from within the manifest:

 {
   ...
   service_worker: {
     src: "app.js",
     scope: "/"
   ...
 }

A Service Worker has an install method which can populate a cache with a web app’s resources when it is registered:

 this.addEventListener('install', function(event) {
  event.waitUntil(
    caches.create('v1').then(function(cache) {
     return cache.add(
        '/index.html',
        '/style.css',
        '/script.js',
        '/favicon.ico'
      );
    }, function(error) {
        console.error('error populating cache ' + error);
    };
  );
 });

So that the app can then respond to requests for resources when offline:

 this.addEventListener('fetch', function(event) {
  event.respondWith(
    caches.match(event.request).catch(function() {
      return event.default();
    })
  );
 });

Rebooting democracy? The case for a citizens constitutional convention.

I’m getting increasingly cynical about our largest organisations and their voting-centred approach to democracy. You vote once, for people rather than programmes, then you’re meant to leave them to it for up to three years until they stand for reelection and in most systems, their actions aren’t compared with what they said they’d do in any way.

I have this concern about Cooperatives UK too, but then its CEO publishes http://www.uk.coop/blog/ed-mayo/2015-02-18/rebooting-democracy-case-citizens-constitutional-convention and I think there may be hope for it yet. Well worth a read if you want to organise better groups.

Hosting Update2

Well after a year the SD card on the Raspberry Pi has failed, I noticed /var was unhappy when I tried to apply the recent Bash updates. Attempts at repair only made things worse and I suspect there is some physical issue. I had minimised writes with logs in tmpfs and the frequently updated weather site sat in tmpfs too..logging to remote systems etc. So not quite sure what happened. Of course this is all very inconvenient when your kit lives in another country, so at some point I guess I will have to build a new SD card and ship it out...for now we are back on Amazon EC2...yay for the elastic cloud \o/

Cloud Computing Deployments … Revisited.

So its been a few years since I’ve posted, because its been so much hard work, and we’ve been pushing really hard on some projects which I just can’t talk about – annoyingly. Anyways, March 20th , 2011 I talked about Continual Integration and Continual Deployment and the Cloud and discussed two main methods – having what we now call ‘Gold Standards’ vs continually updating.

The interesting thing is that as we’ve grown as a company, and as we’ve become more ‘Enterprise’, we’ve brought in more systems administrators and begun to really separate the deployments from the development. The other thing is we have separated our services out into multiple vertical strands, which have different roles. This means we have slightly different processes for Banking or Payment based modules then we do from marketing modules. We’re able to segregate operational and content from personally identifiable information – PII having much higher regulation on who can (and auditing of who does) access.

Several other key things had to change: for instance, things like SSL keys of the servers shouldn’t be kept in the development repo. Now, of course not, I hear you yell, but its a very blurry line. For instance, should the Django configuration be kept in the repo? Well, yes, because that defines the modules and things like URLs. Should the nginx config be kept in the repo? Well, oh. if you keep *that* in then you would keep your SSL certs in…

So the answer becomes having lots of repo’s. One repo per application (django wise), and one repo per deployment containing configurations. And then you start looking at build tools to bring, for a particular server or cluster of servers up and running.

The process (for our more secure, audited services) is looking like a tool to bring an AMI up, get everything installed and configured, and then take a snapshot, and then a second tool that takes that AMI (and all the others needed) and builds the VPC inside of AWS. Its a step away from the continual deployment strategy, but it is mostly automated.

Sony Entertainment Networks Insanity

So, I have a SEN account (it's part of the PSN), I have 2 videos with SEN, I have a broken PS3 so I can no deactivate video (you can only do that from the console itself, yes, really)... and the response from SEN has been abysmal, specifically:

As we take the security of SEN accounts very seriously, we are unable to provide support on this matter by e-mail as we will need you to answer some security questions before we can investigate this further. We need you to phone us in order to verify your account details because we're not allowed to verify details via e-mail.

I mean, seriously, they're going to verify my details over the phone better than over e-mail how exactly? All the contact details are tied to my e-mail account, I have logged in to their control panel and renamed the broken PS3 to "Broken PS3", I have given them the serial number of the PS3, and yet they insist that I need to call them, because apparently they're fucking stupid. I'm damned glad that I only ever got 2 videos from SEN, both of which I own on DVD now anyways, this kind of idiotic tie in to a system is badly wrong.

So, you phone the number... and now you get stuck with hold music for ever... oh, yeah, great customer service here guys. I mean, seriously, WTF.

OK - 10 minutes on the phone, and still being told "One of our advisors will be with you shortly". I get the feeling that I'll just be writing off the 2 videos that I no longer have access to.

I'm damned glad that I didn't decide to buy more content from that - at least you can reset the games entitlement once every six months without jumping through all these hoops (you have to reactivate each console that you still want to use, but hey).

Beginning irc

After some discussion last night at PHP Hants about the fact that irc is a great facilitator of support / discussion, but largely ignored because there is rarely enough information for a new user to get going I decided it may be worth putting together a howto type post so here goes…

What is irc?

First of all, what on earth is it? I’m tempted to describe it as Twitter done right years before Twitter even existed, but I’m a geek and I’ve been using irc for years. It has a long heritage, but unlike the ubiquitous email it hasn’t made the transition into mainstream use. In terms of usage it has similarities to things like Twitter and Instant Messaging. Let’s take a quick look at this.

Twitter allows you to broadcast messages, they get published and anyone who is subscribed to your feed can read what you say. Everything is pretty instant, and if somebody is watching the screen at the right time they can respond straight away. Instant Messaging on the other hand, is more of a direct conversation with a single person, or sometimes a group of people, but it too is pretty instantaneous – assuming, of course, that there’s someone reading what you’ve said. Both of these techonologies are pretty familiar to many. If you go to the appropriate website you are given the opportunity to sign up and either use a web based client or download one.

It is much the same for irc in terms of usage, although conversations are grouped into channels which generally focus on a particular topic rather than being generally broadcast (Twitter) or more specifically directed (Instant Messaging). The downside is that in most cases you don’t get a web page with clear instructions of how to sign up, download a client and find where the best place is to join the conversation.

Getting started

There are two things you need to get going with irc, a client and somewhere to connect to. Let’s put that into a more familiar context.

The client is what you use to connect with; this can be an application – so as an example Outlook or Thunderbird would be a mail client, or IE, Firefox, Chrome or Safari are examples of clients for web pages – or it can be a web page that does the same thing – so if you go to twitter.com and login you are using the web page as your Twitter client. Somewhere to connect to can be compared to a web address, or if you’ve got close enough to the configuration of your email to see the details, your mail server address.

Let’s start with the ‘somewhere to connect to‘ bit. Freenode is one of the most popular irc servers, so let’s take a look. First we’ll see what we can find out from their website, http://freenode.net/.

freenode

There’s a lot of very daunting information there for somebody new to irc, so ignore most of it and follow the Webchat link on the left.

webchat

That’s all very well and good, but what do we put in there? I guess the screenshot above gives a clue, but if you actually visit the page the entry boxes will be blank. Well first off there’s the Nickname, this can be pretty much anything you like, no need to register it – stick to the basics of letters, numbers and some simple punctuation (if you want to), keep it short and so long as nobody else is already using it you should be fine; if it doesn’t work try another. Channels is the awkward one, how do you know what channels there are? If you’re lucky you’re looking into this because you’ve been told there’s a channel there and hopefully you’ve been given the channel name. For now let’s just use the PHP Hants channel, so that would be #phph in the Channels box. Now all you need to do is type in the captcha, ignore the tick boxes and click Connect and you are on the irc channel and ready to chat. Down the right you’ll see a list of who else is there, and in the main window there will be a bit of introductory information (e.g. topic for the channel) and depending on how busy it is anything from nothing to a fast scrolling screen of text.

phph

If you’ve miss typed there’s a chance you’ll end up in a channel specially created for you because it didn’t exist; don’t worry, just quit and try again (I’ll explain that process shortly).

For now all you really need to worry about is typing in text an posting it, this is as simple as typing it into the entry box at the bottom of the page and pressing return. Be polite, be patient and you’ll be fine. There are plenty of commands that you can use to do things, but for now the only one you need to worry about is the one to leave, this is:

/quit

Type it in the entry box, press return and you’ve disconnected from the server. The next thing to look into is using a client program since this is far more flexible, but I’ll save that for another post.

Refocusing Ph.D

Actual progress on this Ph.D revision has been quite slow. My current efforts are on improving the focus of the thesis. One of the criticisms the examiners made (somewhat obliquely) was that it wasn&apost very clear exactly what my subject was: musicology? music information retrieval? computational musicology? And the reason for this was that I failed to make that clear to myself. It was only at the writing up stage, when I was trying to put together a coherent argument, that I decided to try and make it a story about music information retrieval (MIR). I tried to argue that MIR&aposs existing evaluation work (which was largely modelled on information retrieval evaluation from the text world) only took into account the music information needs of recreational users of MIR systems, and that there was very little in the way of studying the music information seeking behaviour of "serious" users. However, the examiners didn&apost even accept that information retrieval was an important problem for musicology, nevermind that there was work to be done in examining music information needs of music scholarship.

So I&aposm using this as an excuse to shift the focus away from MIR a little and towards something more like computational musicology and music informatics. I&aposm putting together a case study of a computational musicology toolkit called music21. Doing this allows me to focus in more detail on a smaller and more distinct community of users (rather than attempting to studying musicologists in general which was another problematic feature of the thesis), it makes it much clearer what kind of music research can be addressed using the technology (all of MIR is either far too diverse or far too generic, depending on how you want to spin it), and also allows me to work with the actually Purcell Plus project materials using the toolkit.

Taking notes in Haskell

The other day we had a meeting at work with a former colleague (now at QMUL) to discuss general project progress. The topics covered included the somewhat complicated workflow that we&aposre using for doing optical music recognition (OMR) on early printed music sources. It includes mensural notation specific OMR software called Aruspix. Aruspix itself is fairly accurate in its output, but the reason why our workflow is non-trivial is that the sources we&aposre working with are partbooks; that is, each part (or voice) of a multi-part texture is written on its own part of the page, or even on a different page. This is very different to modern score notation in which each part is written in vertical alignment. In these sources, we don&apost even know where separate pieces begin and end, and they can actually begin in the middle of a line. The aim is to go from the double page scans ("openings") to distinct pieces with their complete and correctly aligned parts.

Anyway, our colleague from QMUL was very interested in this little part of the project and suggested that we spend the afternoon, after the style of good software engineering, formalising the workflow. So that&aposs what we did. During the course of the conversation diagrams were drawn on the whiteboard. However (and this was really the point of this post) I made notes in Haskell. It occurred to me a few minutes into the conversation that laying out some types and the operations over those types that comprise our workflow is pretty much exactly the kind of formal specification we needed.

Here&aposs what I typed:

module MusicalDocuments where

import Data.Maybe

-- A document comprises some number of openings (double page spreads)
data Document = Document [Opening]

-- An opening comprises one or two pages (usually two)
data Opening = Opening (Page, Maybe Page)

-- A page comprises multiple systems
data Page = Page [System]

-- Each part is the line for a particular voice
data Voice = Superius | Discantus | Tenor | Contratenor | Bassus

-- A part comprises a list of musical sybmols, but it may span mutliple systems
--(including partial systems)
data Part = Part [MusicalSymbol]

-- A piece comprises some number of sections
data Piece = Piece [Section]

-- A system is a collection of staves
data System = System [Staff]

-- A staff is a list of atomic graphical symbols
data Staff = Staff [Glyph]

-- A section is a collection of parts
data Section = Section [Part]

-- These are the atomic components, MusicalSymbols are semantic and Glyphs are
--syntactic (i.e. just image elements)
data MusicalSymbol = MusicalSymbol
data Glyph = Glyph

-- If this were real, Image would abstract over some kind of binary format
data Image = Image

-- One of the important properties we need in order to be able to construct pieces
-- from the scanned components is to be able to say when objects of the some of the
-- types are strictly contiguous, i.e. this staff immediately follows that staff
class Contiguous a where
  immediatelyFollows :: a -> a -> Bool
  immediatelyPrecedes :: a -> a -> Bool
  immediatelyPrecedes a b = b `immediatelyFollows` a

instance Contiguous Staff where
  immediatelyFollows :: Staff -> Staff -> Bool
  immediatelyFollows = undefined

-- Another interesting property of this data set is that there are a number of
-- duplicate scans of openings, but nothing in the metadata that indicates this,
-- so our workflow needs to recognise duplicates
instance Eq Opening where
  (==) :: Opening -> Opening -> Bool
  (==) a b = undefined

-- Maybe it would also be useful to have equality for staves too?
instance Eq Staff where
  (==) :: Staff -> Staff -> Bool
  (==) a b = undefined

-- The following functions actually represent the workflow

collate :: [Document]
collate = undefined

scan :: Document -> [Image]
scan = undefined

split :: Image -> Opening
split = undefined

paginate :: Opening -> [Page]
paginate = undefined

omr :: Page -> [System]
omr = undefined

segment :: System -> [Staff]
segment = undefined

tokenize :: Staff -> [Glyph]
tokenize = undefined

recogniseMusicalSymbol :: Glyph -> Maybe MusicalSymbol
recogniseMusicalSymbol = undefined

part :: [Glyph] -> Maybe Part
part gs =
  if null symbols then Nothing else Just $ Part symbols
  where symbols = mapMaybe recogniseMusicalSymbol gs

alignable :: Part -> Part -> Bool
alignable = undefined

piece :: [Part] -> Maybe Piece
piece = undefined

I then added the comments and implemented the part function later on. Looking at it now, I keep wondering whether the types of the functions really make sense; especially where a return type is a type that&aposs just a label for a list or pair.

I haven&apost written much Haskell code before, and given that I&aposve only implemented one function here, I still haven&apost written much Haskell code. But it seemed to be a nice way to formalise this procedure. Any criticisms (or function implementations!) welcome.

Outlook 2003, Cutting off Emails

I had a friend come to me with an interesting problem they were having in their office. Due to the Exchange server and Office licencing they have they are running Outlook 2003 on Windows 7 64bit Machines.

After Internet Explorer updates to IE11 it introduces a rather annoying bug into Outlook. Typed emails often get cut off mid sentence when you click Send ! So only part of the email gets sent !

What I think is happening is that Outlook is reverting to a previously autosaved copy before sending.

Removing the IE11 update would probably fix it but perhaps the easiest way is to disable the "Autosave unsent email" option in Outlook.

Navigate to:-
Tools, Options, E-Mail Options, Advanced E-Mail Options, and disable the "Autosave unsent" option.

I finally managed to beat my nemesis!

I purchased this book http://www.amazon.co.uk/dp/0738206679 (Linked, by Barabasi) on the 24th of December 2002, I had managed to make 6 or 7 aborted attempts at reading it to completion where life had suddenly got busy and just took over. This meant that I put the book down and didn't pick it up again until things were less hectic some time later and I started again.

Anyhow, I finally beat the book a few nights ago, my comprehension of it was pretty low anyhow but at least it is done. Just shows I need to read lots more given how little went in.

Why buying a Mio Cyclo 305 HC cycling computer was actually a great idea.

I finally made it back out onto the bike today for the first time since September last year. I'd spent some time ill in October and November which meant I had to stop exercising and as a result I've gained loads of weight over the winter and it turns out also become very unfit which can be verified by looking at the Strava ride from today: http://www.strava.com/activities/110354158

Anyhow, a nice thing about this ride is that I can record it on Strava and get this data about how unfit I have become, this is because last year I bought a Mio Cyclo 305 HC cycle computer http://eu.mio.com/en_gb/mio-cyclo-305-hc.htm from Halfords reduced to £144.50 (using a British Cycling discount). I was originally going to get a Garmin 500 but Amazon put the price up from £149.99 the day I was going to buy it to £199.99.

I knew when I got the Mio that it had a few issues surrounding usability and features but it was cheap enough at under £150 that I figured that even if I didn't get on with it I'd at least have a cadence sensor and heart rate monitor so I could just buy a Garmin 510 when they sorted out the firmware bugs with that and the price came down a bit which is still my longer term intention.

So it turns out a couple of weeks ago I plugged my Mio into a Windows VM when I was testing USB support and carried out a check for new firmware. I was rather surprised to see a new firmware update and new set of map data was available for download. So I installed it think I wasn't going to get any new features from it as Mio had released some new models but it turns out that the new firmware actually enables a single feature (amongst other things, they also tidied up the UI and sorted a few other bugs along with some other features) that makes the device massively more useful as it now also creates files in .fit format which can be uploaded directly to Strava.

This is massively useful for me as although the Mio always worked in Linux as the device is essentially just a USB mass storage device but you would have to do an intermediate step of having to use https://github.com/rhyas/GPXConverter to convert the files from the Mio-centric GPX format to something Strava would recognise. Now I can just browse to the folder and upload the file directly which is very handy.

All in it turns out that buying a Mio which reading reviews and forums were full of doom and gloom means I can wait even longer before considering replacement with a garmin.

Wow, I do believe Fasthosts have outdone themselves...

So, got a beep this morning from our work monitoring system. One of our customers domain names is hosted with livedns.co.uk (which, as far as I can tell, is part of the Fasthosts franchise)... It appears that Fasthosts have managed to entirely break their DNS:

brettp@laptop:~$ host www.fasthosts.com
;; connection timed out; no servers could be reached
brettp@laptop:~$ whois fasthosts.com | grep -i "Name Server"
   Name Server: NS1.FASTHOSTS.NET.UK
   Name Server: NS2.FASTHOSTS.NET.UK
Name Server: NS1.FASTHOSTS.NET.UK
Name Server: NS2.FASTHOSTS.NET.UK
brettp@laptop:~$ whois fasthosts.net.uk | grep -A 2 "Name servers:"
    Name servers:
        ns1.fasthosts.net.uk      213.171.192.252
        ns2.fasthosts.net.uk      213.171.193.248
brettp@laptop:~$  host -t ns fasthosts.net.uk 213.171.192.252
;; connection timed out; no servers could be reached
brettp@laptop:~$ host -t ns fasthosts.net.uk 213.171.193.248
;; connection timed out; no servers could be reached
brettp@laptop:~$

So, that's fasthosts core nameservers not responding, good start! They also provide livedns.co.uk, so lets have a look at that:

brettp@laptop:~$ whois livedns.co.uk | grep -A 3 "Name servers:"
    Name servers:
        ns1.livedns.co.uk         213.171.192.250
        ns2.livedns.co.uk         213.171.193.250
        ns3.livedns.co.uk         213.171.192.254
brettp@laptop:~$ host -t ns ns1.livedns.co.uk 213.171.192.250
;; connection timed out; no servers could be reached
brettp@laptop:~$ host -t ns ns1.livedns.co.uk 213.171.193.250
;; connection timed out; no servers could be reached
brettp@laptop:~$ host -t ns ns1.livedns.co.uk 213.171.192.254
;; connection timed out; no servers could be reached

So, erm, apparently that's all their DNS servers "Not entirely functioning correctly"! That's quite impressive!

A year in Prog!


It's New Year's Day 2014 and I'm reflecting on the music of past year.

Album wise there were several okay...ish releases in the world of Progressive Rock. Steven Wilson's The Raven That Refused To Sing not the absolute masterpiece some have eulogised a solid effort though but it did contain some filler. Motorpsyco entertained with Still Life With Eggplant not as good as their previous album but again a solid effort. Magenta as ever didn't disappoint with The 27 Club, wishing Tina Booth a swift recovery from her ill health.

The Three stand out albums in no particular order for me were Edison's Children's Final Breath Before November which almost made it as album of the year and Big Big Train with English Electric Full Power which combined last years Part One and this years Part Two with some extra goodies to make the whole greater than the sum of the parts. Also Adrian Jones of Nine Stones Close fame pulled one out of the bag with his side Project Jet Black Sea which was very different and a challenging listen, hard going at first but surprisingly very good. This man is one superb guitarist especially if you like emotion wrung out of the instrument like David Gilmore or Steve Rothery.

The moniker of Album of the Year this year goes to Fish for the incredible Feast of Consequences. A real return to form and his best work since Raingods With Zippos. The packaging of the deluxe edition with a splendid book featuring the wonderful artwork of Mark Wilkinson was superb. A real treat with a very thought provoking suite about the first world war really hammed home the saying "Lest we forget". A fine piece that needs to be heard every November 11th.


Gig wise again Fish at the Junction in Cambridge was great. His voice may not be what it was in 1985 but he is the consummate performer, very at home on the stage. As a raconteur between songs he is as every bit as entertaining as he is singing songs themselves.

The March Marillion Convention in Port Zealand, Holland where they performed their masterpiece Brave was very special as every performance of incredible album is. The Marillion Conventions are always special but Brave made this one even more special than it would normally be.
Gig of the year goes again to Marillion at Aylesbury Friars in November. I had waited thirty years and forty odd shows to see them perform Garden Party segued into Market Square Heroes that glorious night it came to pass, I'm am now one very happy Progger or should that be Proggie? Nevermind Viva Progressive Rock!

Scratch in a network environment

I have been running a Code Club at my local Primary School for a while now, and thought it was about time I put details of a few tweaks I’ve made to the default Scratch install to make things easier. So here goes:

With the default install of Scratch (on Windows) projects are saved to the C: drive. For a network environment, with pupils work stored on a network drive so they always have access whichever machine they sit at, this isn’t exactly helpful. It also isn’t ideal that they can explore the C: drive in spite of profile restrictions (although it isn’t the end of the world as there is little they can do from Scratch).

save-orig

After a bit of time with Google I found the answer, and since it didn’t immediately leap out at me when I was searching I thought I’d post it here (perhaps my Google Fu was weak that day). It is actually quite simple, especially for the average Code Club volunteer I should imagine; just edit the scratch.ini file. This is, as would be expected, located in:

C:\Program Files\Scratch\Scratch.ini

Initially it looks like this:

ini-orig

Pretty standard stuff, but unfortunately no comments to indicate what else you can do with it. As it happens you can add the following two lines (for example):

Home=U:
VisibleDrives=U:

To get this:

ini-new

They do exactly what is says on the tin. If you click on the Home button in a file dialogue box then you only get the drive(s) specified. You can also put a full path in if you want to put the home directory further down the directory structure.

save-new1

The VisibleDrives option restricts what you can see if you click on the Computer button in a file dialogue box. If you want to allow more visible drives then separate them with a comma.

save-new2

You can do the same with a Mac (for the home drive), just use the appropriate directory format (i.e. no drive letter and the opposite direction slash).

There is more that you can do, so take a look at the Scratch documentation here. For example if you use a * in the directory path it is replaced by the name of the currently logged on user.

Depending on your network environment it may be handy for your Code Club to put the extra resources on a shared network drive and open up an extra drive in the VisibleDrives. One I haven’t tried yet it is the proxy setting, which I hope will allow me to upload projects to the Scratch website. It goes something like:

ProxyServer=[server name or IP address]
ProxyPort=[port number]

Sampler plugin for the baremetal LV2 host

I threw together a simpler sampler plugin for kicks. Like the other plugins it sounds fairly underwhelming. Next challenge will probably be to try plugging in some real LV2 plugins.

Baremetal MIDI machine now talks to hardware MIDI devices

The Baremetal MIDI file player was cool, but not quite as cool as a real instrument.

I wired up a MIDI In port along the lines of This one here, messed with the code a bit and voila (and potentially viola), I can play LV2 instrument plugins using a MIDI keyboard:

When I say "LV2 synth plugins", I should clarify that I'm only using the LV2 plugin C API, not the whole .ttl text file shebangle. I hope to get around to that at some point but it will be a while before you can directly plug LV2s into this and expect them to just work.

LinuxMint 14 Add Printer Issue


 LinuxMint 14 Add Printer Issue



 

I wanted to print from my LinuxMint 14 (Cinnamon) PC via a shared Windows printer on my network. Problem is it isn’t found by the printers dialog in system settings. I thought I’d done all the normal things to get samba to play nice like rearranging the name resolve order in /etc/samba/smb.conf to a more sane bcast host lmhosts wins. Having host and wins, neither of which I’m using first in the order cocks things up some what. Every time I tried to search for the printer in the system setting dialog it told me “FirewallD is not running. Network printer detection needs services mdns, ipp, ipp-client and samba-client enabled on firewall.” So much scratching of the head there then, because as far as I can tell there ain’t no daemon by that name available!

It turns out thanks to /pseudomorph this has been a bug since LinuxMint12 (based on Ubuntu 11.10). It’s due to that particular daemon (Windows people daemon pretty much = service) being Fedora specific and should have no place in a Debian/Ubuntu based distribution. Bugs of this nature really should be ironed out sooner.

Anyway the simple fix is to use the more traditional approach using the older printer dialog which is accessed by inputting system-config-printer at the command line. Which works just fine so why the new (over a year old) printer config dialog that is inherently broken I ask myself.

The CUPS web interface also works apparently http://localhost:631/ in your favourite browser which should be there as long as CUPS is installed which it is in LinuxMint by default.

So come on Minty people get your bug squashing boots on and stamp on this one please.

Update

Bug #871985 only affects Gnome3 so as long as its not affecting Unity that will be okay Canonical will it!

On Music

Lately, (well I say lately, I think it’s been the same for a few years now) I have been finding that it is very rare that an album comes along that affects me in a way that music I heard 10 years ago seem to. That is not to say that I have not heard any music that I like in that time, it just doesn’t seem to mean as music that has been in my life for years. What I am trying to work out is if that is a reflection on the state of music, of how I experience music or just me.

Buying

Buying music was always quite an experience. I would spend weeks, months and sometimes longer saving up to buy some new music. Whether I knew exactly what I wanted or just wanted “something else by this artist” I would spend some time browsing the racks weighing up what was the best value for my money. In the days before the internet, if you wanted to research an artist’s back catalogue, you were generally out of luck unless you had access to books about the artists. This lead to the thrill of finding a hidden gem in the racks that you didn’t know existed or had only heard rumours about. The anticipation of listening to the new music would build even more because I would have to wait until I had travelleled home before I could listen to my new purchases.

Nowadays, with the dizzying amount of music constantly pumped into our ears through the internet, radio, advertising and the plethora of styles and genres, it is difficult to sift through and find artists and music that really speak to you. Luckily, there are websites available to catalogue releases by artists so you are able to do thorough research and even preview your music before you purchase it. Of course the distribution methods have changed massively too. No longer do I have to wait until I can make it to a brick and mortar store to hand over my cash. I can now not only buy physical musical releases on CD or Vinyl online and have it delivered to my door, I can also buy digital music through iTunes, Amazon or Bandcamp or even stream the music straight to my ears through services like Spotify or Rdio. Whilst these online sales avenues are great for artists to be able to sell directly to their fans, I feel that some of the magic has been removed from the purchasing of music for me.

Listening

Listening to the music used to be an even greater event than purchasing it. After having spent the time saving up for the purchase, then the time carefully choosing the music to buy and getting it home, I would then sit myself down and listen to the music. I would immerse myself totally in the music and only listen to it (I might read the liner notes if I hadn’t exhausted them on the way home). It is difficult to imagine doing one thing for 45+ minutes without the constant interruptions from smartphones, tablet computers, games consoles and televisions these days. I can’t rememeber the last time I listened to music on good speakers or headphones (generally I listen on crappy computers speakers or to compressed audio on my iPhone through crappy headphones) without reading Twitter, replying to emails or reading copiuous amounts of information about the artists on Wikipedia. This all serves to distract from the actual enjoyment of just listening to the music.

Experience

The actual act of writing this blog post has called into sharp focus the main reason why music doesn’t seem to affect me nowadays as much as it used to - because I don’t experience it in the same way. My life has changed, I have more resposibilities and less time to just listen which makes the convenience and speed of buying digital music online much more appealing. You would think that this ‘instant music’ should be instantly satisfying but for some reason it doesn’t seem to work that way.

What changed?

I wonder if I am the only one experiencing this? My tastes in music have definitely changed a lot over the last few years, but I still find it hard to find music that I want to listen to again and again. I’m hoping I’m not alone in this, alternatively I’m hoping someone might read this and recommend some awesome music to me and cure this weird musical apathy I appear to me suffering from.

My tastes in music have definitely changed a lot over the last few years, but I still find it hard to find music that I want to listen to again and again. I’m hoping I’m not alone in this, alternatively I’m hoping someone might read this and recommend some awesome music to me and cure this weird musical apathy I appear to me suffering from.

Black redstarts

It's difficult to use the terrace for a couple of weeks, because the black redstart family is in their summer residence at the top of a column under the roof. The chicks grow very fast, and the parents have to feed them frequently; when anyone goes out on the terrace they stop the feeding process and click shrill warnings to the chicks to stay still. I worry that if we disturb them too often or for too long the chicks will starve.

Black redstarts are called rougequeue noir (black red-tail) in French, but here they are known as rossignol des murailles (nightingale of the outside walls). Pretty!

The camera needs replacing, so there are no photos of Musatelier's rossignols des murailles, but you can see what they look like on http://fr.wikipedia.org/wiki/Rougequeue_noir.

Roundabout at Mirambeau

Roundabouts are taken seriously here in France. Not so much as traffic measures (though it has been known for people to be cautioned by the local gendarmes for not signalling when leaving a roundabout, and quite rightly too), but as places to ornament.

A couple of years ago the roundabout at the edge of  Mirambeau had a make-over which included an ironwork arch and a carrelet (fishing hut on stilts). Now it has a miniature vineyard as well, and roses and other plants for which this area is known.

Need a passenger to take photo!

Some new photos

Take a look at some new photos my father and I have taken. We are experimenting with our new digital SLR with a variety of lenses.
