Odroid UX4

2015-12-06T21:19:00.003+00:00

My Raspberry Pi died so I replaced it with the 8 core Odroid UX4.

ODROID-XU4 is a new generation of computing device with more powerful, more energy-efficient hardware and a smaller form factor.
Offering open source support, the board can run various flavors of Linux, including the latest Ubuntu 15.04 and Android 4.4 KitKat and 5.0 Lollipop.
By implementing the eMMC 5.0, USB 3.0 and Gigabit Ethernet interfaces, the ODROID-XU4 boasts amazing data transfer speeds, a feature that is increasingly required to support advanced processing power on ARM devices.

Set the fan

I was worried about the noise. It is not loud but audible. After:

change the governor to "interactive" from "performance"

XQDT in Eclipse Kepler

2014-05-02T23:46:00.004+01:00

XQDT provides support for editing, execution, and debugging of XQuery modules in Eclipse.

It requires DLTK version 3. Certain plugins will install DLTK version 4, e.g. Scala IDE, which prevents XQDT installation.
If that is not installed then version 3 of DLTK can be installed from the indigo update site
http://download.eclipse.org/releases/indigo

Then install XQDT

Updating the Pipo M9

2014-04-26T11:13:00.001+01:00

I tried Pipo-M9-Pro-RileyROM-2-7-KitKat 2.7.2 on my Pipo M9. It looks good and is much faster than the Finless Jellybean ROM, but it has a battery problem and more importantly Linuxdeploy fails with permissioning errors. This is a KitKat issue I believe. Other minor issues:
Screen rotation:

It's a problem with occurs mostly when using the stock launcher. If you use another like Nova or Apex, then the problem don't exist.

GPS:

I do sync time with NTPSync before trying the first time, maybe that's the trick.

So back to JellyBean, not with the Finless ROM this time but Pipo-M9-Pro-RileyROM-2-7-Jellybean. Fast and clean, the only gripe is the slow boot time.

A very rough guide to running BaseX on Openshift

2014-03-22T19:07:00.001+00:00

Update: 24Apr2014 see openshift-basex-quick-start

I hope to release an Openshift quick start cartridge for BaseX soon. Until then here are some quick notes that completely ignore the right way to do this.

1. Use putty to access your gear: https://www.openshift.com/blogs/access-your-application-gear-using-ssh-with-putty

2. Install BaseX

cd app-root/data
wget http://files.basex.org/releases/BaseX-latest.zip
unzip *.zip

3. In jetty.xml change the host and port settings to use Env values

<New class="org.eclipse.jetty.server.nio.SelectChannelConnector">
    <Set name="port"><Env name="OPENSHIFT_DIY_PORT" default="8080" /></Set>
    <Set name="host"><Env name="OPENSHIFT_DIY_IP" default="127.0.0.1" /></Set>
    <Set name="maxIdleTime">60000</Set>
    <Set name="reuseAddress">true</Set>
    <Set name="Acceptors">2</Set>
    <!-- Support for SSL connections . <Set name="confidentialPort">8986</Set> -->
</New>

4. If the default server, (ruby?) is running kill it.

5. Start the BaseX httpserver
#!/bin/bash

# start basex
cd ${OPENSHIFT_DATA_DIR}basex
nohup bin/basexhttp -X -Dorg.basex.SERVERHOST=$OPENSHIFT_DIY_IP \
-X -Dorg.basex.SERVERPORT=$OPENSHIFT_DIY_PORT \

Schematron resources

2014-02-07T13:32:00.000+00:00

At the beginning of the week I needed to create a Schematron sample in a hurry. I had done it before, a long time ago, on another machine. It did not help that http://www.schematron.com was, and still is, down. This article is a record of the resources I found at the time and later.

First https://code.google.com/p/schematron/ seems to be the place to get an implementation of ISO Schematron. This comes as a set of XSLT files. The wiki suggests a number of options for running these, which led me to the excellent tutorial at http://www.dpawson.co.uk/schematron/.

In a hurry and not wanting to set up a batch file I remembered that Kernow has a Schematron option. Sadly I could not find any documentation for this and the Web start option seems to have become a victim of enhanced security policies.

Another useful tutorial, with example business logic from the Ark, is data2type schematron introduction

XML Database Schematron support

eXistDb :uses Jing, which does not support the ISO version.
BaseX there are a couple of embedded uses in github projects.
Zorba nothing yet.
MarkLogic has ML-Schematron.

Other tools

XProc has validate-with-schematron.
quixschematron has streaming support.
http://code.google.com/p/phloc-schematron/ Apache Licence
http://www.probatron.org/ is another implementation with Java and .Net support.

It seems to me it would be nice to have a http://expath.org/ module that wrapped up the Schematron functionality and made it easy to install. Something like ML-Schematron that could run in BaseX or ExistDb.
