Recipe: Burger Patties

2012-01-02T15:12:00.000+13:00

Low carb, gluten free hamburger patties for our whole family.

You will need:

400g cheap minced beef
3 cloves of garlic, crushed
½ teaspoon mustard powder
¼ teaspoon ground black pepper
a pinch of paprika
1 small egg

Combine all ingredients and mix well with your hands. Separate the mixture into balls about 5 cm across, or about 60 g.

To cook, flatten the balls to less than 1 cm, and cook with a little dripping on a frying pan or barbecue until done, turning once when the bottom is brown.

Uncooked patties can be frozen with baking paper between them.

Recipe: Lamb Rogan Josh

2011-10-29T15:42:00.000+13:00

This recipe is based on the excellent Route 79 Rogan Josh recipe, updated to ensure it contains absolutely no chilli or wheat products, so my wife and kids can eat it. It’s one of the kids’ favorite meals, and the only way Trina will eat lamb.

This recipe makes far too much, so we freeze the extra for another few kids’ meals when they’re tired and we don’t have time to cook.

You will need:

About 700g of lamb.
A thumb-sized chunk of ginger.
Two or three cloves of garlic.
2 teaspoons salt.
1 teaspoon turmeric.
4 teaspoons whole coriander seed.
3 teaspoons whole cumin seed.
3 cardamom pods.
1/4 teaspoon ground cinnamon.
3 cloves.
1/4 teaspoon peppercorns.
A pinch of ground nutmeg.
One star anise.
One bay leaf.
Chilli powder to taste.
One large onion.
A sploosh of oil.
Two 400g tins of chopped tomatoes.
A cup or so of coriander leaves (cilantro).
A large pot, and a couple of hours until dinner
A cup or so of basmati rice.

Remove the lamb from the bone, and chop it into bite size pieces, removing the worst of the fat. Roughly peel then grate the ginger with a Microplane or similar, peel and crush the garlic, and grind the coriander seed, cumin seed and pepper in an electric grinder.

Sploosh some oil into the pot, and chop the onion while it is heating. Fry the onion with the garlic and ginger until it goes soft, then add the salt and all the ground spices and keep frying. Some of the spices may stick to the pot, but keep stirring to make sure they don’t burn.

After a few minutes, add the lamb, the bay leaf and the rest of the spices. (Keep the coriander leaves for later.) Keep stirring while browning the lamb. As the fat cooks off the lamb you should be able to start scraping off any spices that were stuck to the bottom of the pot.

Once the lamb is browned and coated with the spices, add the tins of tomatoes. Put the lid on the pot and bring it to the boil, then turn it right down. Put the rice in lots of water to soak.

Let the pot simmer quietly for half an hour, then give it a stir. After another half an hour, chop the coriander leaves and stir them in, then keep cooking, stirring regularly to make sure it doesn’t catch. Drain and rinse the rice, and start cooking it however you prefer.

When the rice is done, serve it with the lamb on top, and put any leftover lamb in the freezer for later. Try not to serve the bay leaf or the star anise to the kids. Enjoy!

Nokia M11 Interface Address via SNMP

2004-06-22T20:00:00.000+12:00

I used to use a Nokia M11 to connect to the Internet. The M11 actsas a router, so the IP address of the router on the Internet bore noresemblance to the IP address of my computer. However, I needed thatexternal address to send to DynDNS.org.

The M11 supports SNMP, so I wrote a short shell script usingNET-SNMP. It finds theexternal IP address in two steps:

Loop through the network interface descriptions under ifDescr to find the ifIndex of the PPP interface.
Loop through the IP addresses under ipAdEntIfIndex to find the matching index, and get the IP address of the selected interface from ipAdEntAddr.

The command line syntax has probably changed since I used this program,so you might need to make some minor changes.

Python fcrypt

2004-02-20T20:24:00.000+13:00

I’ve written a pure Python implementation of the Unix crypt(3) algorithm, and packaged it with Distutils and with doc strings for pydoc and doctest. It’s based on Eric A. Young’s optimised fcrypt code, which was written in C.

Download the most recent version:

fcrypt-1.3.1.tar.gz (11K)

There are some known problems with this software:

The bitwise arithmetic relies on the specific behaviour of Python 2.2 and earlier when overflowing an integer on 32-bit architectures. Python 2.3 works the same but generates a very large number of warnings. Python 2.4 converts many of the intermediate results from the int to the long type, which still works, but is a bit slower.

Since I don’t really understand how the original algorithm and C code works, fixing this is quite difficult for me.
If you try to use MD5-crypted passwords which use a salt beginning with $1$ , the current version uses $1 as the salt, and the DES crypt algorithm.

In view of the preceding points, and the low security provided by the DES-based password hashing algorithm, I recommend that you use Michal Wallace’s md5crypt unless you really need compatibility with other software using the same algorithm. In a future version, I may try to provide MD5-based hashing in addition to the current algorithm.

If you’re still on Python 2.3 and you’d like to just get rid of the warnings, you have two options. You could add a command line option when you start Python:

    python2.3 -Wignore::FutureWarning:fcrypt ...

Or you could include extra code before importing the module:

    import warnings
    warnings.filterwarnings('ignore', '', FutureWarning, 'fcrypt$', 0)

CD-ROM Access in Python

2004-01-19T15:33:00.000+13:00

Quite some time ago I had the idea of writing aPython program to access theCDDB.This didn’t get very far, but the code samples I came up with might beuseful to someone else.

If you’re looking for other software like this,Ben Gertzfield has his ownCDDB modules forPython.

There are three files for download here:

cddbid.py is a small module tocalculate the CDDB ID for a CD-ROM, given the track lengths.
cdtoc.py is some example code that usesthe ioctl functions in Python to retrieve the track lengths from aCD-ROM, at least under x86 Linux.
CDROM.py is an automatically generatedfile from the Linux cdrom.h header, that provides constants needed bycdtoc.py.

XSLT, CDATA and disable-output-escaping

2003-08-01T12:00:00.000+12:00

This document elaborates on my ideas about XSLT in response toKevin Davis’sexperimentswith Movable Type at Alazanto.

Be warned that really understanding this document will require agood knowledge of XML and XSLT, although I have tried to make theexplanation and examples as clear as possible.

The Problem

Kevin has been experimenting with using XSLT to format simple XMLoutput from Movable Type into a complete web page. Originally, heincluded the data for each weblog entry in a CDATA section containingliteral XHTML, in much the same way as many RSS feeds. See thefollowing example, reformatted for clarity:

<entry>
 <title>entry with images</title>
 <date>August 09, 2003</date>
 <author>Kevin</author>
 <idnum>000033</idnum>
 <permalink>http://alazanto.org/xml/archives/000033.xml</permalink>
 <body xmlns:html="http://www.w3.org/1999/xhtml"><![CDATA[<p><img
  class="archive" align="right" src="http://alazanto.org/images/sample.jpg"
  alt="photograph of a flower, just for show"/>Mauris felis elit, varius
  quis, pulvinar vel, sodales vehicula, mi. Nunc elementum pharetra elit.
  </p>]]>
 </body>
 <more xmlns:html="http://www.w3.org/1999/xhtml"><![CDATA[]]></more>
 <comment-link>http://alazanto.org/xml/archives/000033_comments.xml</comment-link>
 <comment-count>6</comment-count>
</entry>

The XML CDATA markup indicates that the data between<![CDATA[ and ]]> should not beinterpreted as XML with elements and entity references resolved.Instead, the data is included as a literal string, exactly asif each <, > and &had been encoded as <, > and& respectively. The result is a DOM tree likethe following:

<entry>
- <title>
  - 'entry with images'
- <date>
  - 'August 09, 2003'
- <author>
  - 'Kevin'
- <idnum>
  - '000033'
- <permalink>
  - 'http://alazanto.org/xml/archives/000033.xml'
- <body>
  - '<p><img class="archive" align="right" src="http://alazanto.org/images/sample.jpg" alt="photograph of a flower, just for show"/>Mauris felis elit, varius quis, pulvinar vel, sodales vehicula, mi. Nunc elementum pharetra elit.</p>'
- <more>
- <comment-link>
  - 'http://alazanto.org/xml/archives/000033_comments.xml'
- <comment-count>
  - '6'

Note that in this DOM, the child text node of the<body> element is just a string, withno special meaning to an XML parser or an XSLT processor, even if itlooks to you like a paragraph from an XHTML document.

We can write fairly simple XSLT templates to turn this XML intoXHTML for the browser. To include the literal XHTML in the result, wecan try theXSLTdisable-output-escaping attribute, with a templatesomething like this:

<xsl:template match="entry">
  <div class="entry">
    <h2><xsl:value-of select="title"/></h2>
    <xsl:value-of select="body" disable-output-escaping="yes"/>
  </div>
</xsl:template>

Without the disable-output-escaping attribute, thestring value of the <body> element would be writtento the output so that it could be read in again by another XML parser.In other words, each < would be escaped as<, each & as&, and each > as>.

When processed in Internet Explorer, or a stand-alone XSLTprocessor, the disable-output-escaping attribute disablesthis escaping step, so that the text child of the<body> node is included literally in the outputfile as shown below, which is what Kevin expected:

<div class="entry">
 <h2>entry with images</h2>
 <p><img class="archive" align="right"
  src="http://alazanto.org/images/sample.jpg"
  alt="photograph of a flower, just for show"/>Mauris felis elit,
 varius quis, pulvinar vel, sodales vehicula, mi. Nunc elementum
 pharetra elit... </p>
</div>

The problem occurs when trying to use the same templates inMozilla. The Mozilla XSLT processor doesn’t supportdisable-output-escaping, since it transforms directlyfrom the source DOM to a destination DOM tree, without an output stepin which to disable escaping. The DOM that Mozilla constructs isquite predictable, but not what Kevin wanted:

<div>
- @class='entry'
- <h2>
  - 'entry with images'
- '<p><img class="archive" align="right" src="http://alazanto.org/images/sample.jpg" alt="photograph of a flower, just for show"/>Mauris felis elit, varius quis, pulvinar vel, sodales vehicula, mi. Nunc elementum pharetra elit... </p>'

This means that Mozilla displays the markup to theuser, complete with <p> and<img> tags, instead of the paragraph text with afloating image. Mozilla bug 98168 is about this behaviour, andcomment11 states quite clearly that it is expected and will not be changed.

The Solution

The solution for Kevin is to create the original XML file withoutenclosing the paragraph in a CDATA section, making the image andparagraph tags real elements in the source XML DOM, so that they canbe copied directly to the destination XHTML DOM. This small change tothe source XML gives us a very different source DOM tree:

<entry>
- <title>
  - 'entry with images'
- <date>
  - 'August 09, 2003'
- <author>
  - 'Kevin'
- <idnum>
  - '000033'
- <permalink>
  - 'http://alazanto.org/xml/archives/000033.xml'
- <body>
  - <p>
    - <img>
      - @class='archive'
      - @align='right'
      - @src='http://alazanto.org/images/sample.jpg'
      - @alt='photograph of a flower, just for show'
    - 'Mauris felis elit, varius quis, pulvinar vel, sodales vehicula, mi. Nunc elementum pharetra elit.'
- <more>
- <comment-link>
  - 'http://alazanto.org/xml/archives/000033_comments.xml'
- <comment-count>
  - '6'

With this input, the XSLT to copy the nodes can be just as simple,using xsl:copy-of to copy all the elements underthe source <body> element, but not the elementitself:

<xsl:template match="entry">
 <div class="entry">
  <h2><xsl:value-of select="title"/></h2>
  <xsl:copy-of select="body/*"/>
 </div>
</xsl:template>

By copying elements instead of literal XHTML source code, Mozilladisplays the page from the correct DOM tree, and it works just as well withInternet Explorer and external XSLT processors. The result looks verysimilar to the input DOM:

<div>
- @class='entry'
- <h2>
  - 'entry with images'
- <p>
  - <img>
    - @class='archive'
    - @align='right'
    - @src='http://alazanto.org/images/sample.jpg'
    - @alt='photograph of a flower, just for show'
  - 'Mauris felis elit, varius quis, pulvinar vel, sodales vehicula, mi. Nunc elementum pharetra elit.'

You can see the result of this in Kevin’sexample XML weblog, in any web browser that supports XSLT.

(Finally, thanks to Kevin for using the<xsl:copy-of> element, which I’d managed to miss infour years of reading the XSLT spec.)

Using x3270 with an IBM AS/400

1998-11-08T21:55:00.000+13:00

There have been a few questions asked on comp.sys.ibm.as400.misc aboutaccessing an AS/400 “green screen” display from Unix. This pagedescribes how I had it set it up very nicely under Linux using thex3270 terminal emulator.

My environment was:

A model 4609-510 AS/400 with OS/400 V4R2, and configured forTCP/IP on an Ethernet LAN.
A IBM PC with a Pentium processor running Debian GNU/Linux 2.0.
The version of x3270 from this version of Debian, which is3.1.1.9.
I’ve used this basic setup for versions of x3270 from before3.1.1.5, and from OS/400 V3R6.

(Since I first wrote this document, a few links to it have appeared on various web pages, and I’ve started then stopped maintaining x3270 for Debian.)

Introduction

The first thing to do is to get x3270 compiled, installed andconfigured to connect to the AS/400 system. This is all fairly wellcovered in x3270’s documentation, so I won’t expand on it here.

When you connect to the AS/400 using x3270, you will (surprise!)be using a 3270 data stream, which the AS/400 converts to a 5250 datastream for you. Recent versions of x3270 emulate a 3279 device, whichhas the enhanced features necessary for all the colours andhighlighting to be displayed. In fact, I found the effects to becloser to what is described in the DDSReference than any other PC emulator.

System Request support

A problem with all official releases of x3270 up to 3.1.1.7, isthat there is no way to use System Request to interrupt a display thathas the keyboard locked. The new TN3270E RFC defines the 3270 Attnfunction as sending a telnet ‘Interrupt Process’ code, which is notwhat x3270 normally sends. It turns out that the AS/400 supports thiscode for System Request.

For System Request to work properly, I recommend compiling thelatest version of x3270.

Configuring for AS/400

All the configuration you need should be taken care of by my .x3270pro file. Make sure there’s nothing youwant to keep in your current one, then drop mine in your homedirectory. If you’re the latest version of x3270, use the .x3270pro patched file instead. Then startup x3270 and try it!

This is what the file actually does:

The first long section following“x3270.keymap.5250” defines a new keyboard mapping thattranslates the key you press (like F2) into what the AS/400 emulatorwants to see (PA1 followed by PF2). A special one is Shift-Home,which is useful with SDA. You’ll know if you need it.
You must use a model 2 (with an 80x24 screen) because that’sthe size of screen the AS/400 draws on.
I use the ‘alt’ character set to enable my Alt key,overridden by the 5250 mappings above.
The ‘us-intl’ character set seems to correspond almostexactly with CCSID 37, which is the default CCSID at my site. Thisrepresents the US English code page. In particular, the brackets ‘[’and ‘]’ work. (See some of the members in QSYSINC/H for examples.)Only the pilcrow sign ‘¶’ is represented differently.
‘blankFill’ makes entry fields work better when inserting atthe start.

Problems

Unfortunately, the 3270 display does not support the keyboardshift and validation of a real 5250 and these functions are providedby the AS/400. This means that input in an uppercase only field willappear however you type it.
The Field Exit, Field + and Field - keys are not supported bythe AS/400’s emulation, so my key mappings simulate it by erasing tothe end of the field then tabbing to the next field. This usuallyworks fine except with negative numbers, which I have trouble with.ISTR having other problems on V3R6.

Introduction to Scripting

1998-08-10T19:00:00.000+12:00

In August 1998, the local LinuxUsers’ Group had a meeting for its members, where three presentationswere given about topics related to Linux. This page links tomaterials from my presentation about scripting.

My presentation focussed on four languages:

You can download three files containing material for my presentation:

The PDF file of the slides;
The LaTeX source for the slides;
The gzipped tar file containing the example scripts I prepared.

Not all the examples described in the slides were written. The GUIexample was not written for sh, because there is no GUI libraryavailable on Linux. With CDE installed, theremight be dtksh, but I’ve never used CDE. The scripts to check a webpage were not written due to lack of time.
