ST 4U 206: Introducing Log4s

March 14, 2012 11:01:42.253

Today's Smalltalk 4 You looks at log4s (a logging framework) in VA Smalltalk. Today we just scratch the surface; there will be more screencasts on this topic. If you have trouble viewing it here in the browser, you can also navigate directly to YouTube. To watch now, click on the image below:

log4s.

Today we'll look at the logging framework that ships with VA Smalltalk - log4s (A Smalltalk port of the well known log4J package). It's already in your image, so there's no need to load it from ENVY. There are a couple of different ways to get started, but today we'll look at setting it up via the ini file. Every VA image has a corresponding (same base name) ini file - you'll want to append a new "stanza" to it. Here we are setting up a basic file logger, using the default root level logger. You can have multiple logging streams (each filtered separately) on a single logger; today we'll just look at a simple file logger. Here's the way we define that in the ini file:


[log4s]
debugEnabled=true
quietMode=false
globalLevel=All
dailyRollingFileAppender =(fileAppender, root, vaLog.log, false, Info, EsPatternLayout,
 'ڴe{ISO8601}: [%level] %message', true, topOfDay )


What that sets up is a file logger off the root (technically, a new appender - each logger can have any number of appenders associated with it). When you log something, it will appear in that log file (we specified vaLog.log above). The pattern specified how the log entry appears; the VA documentation goes through in great detail how you can customize that. To log a warning, you can do something like this:


"simple log event"
EsLogManager warn: 'This is a warning, beware!'

One caveat - the doc talks about class LogManager, while it's actually EsLogManager. The output for what we did above?

Logging

We'll get into filtering, programmatic setup and more in the future screencasts

Patents and Copyrights Jump the Shark

March 13, 2012 22:16:07.052

I think it's time to seriously consider ending copyrights and patents completely. Ask yourself - could a complete free for all be worse than what we have now?

While most of the tech world was partying at South by Southwest in Austin yesterday, Yahoo announced it was filing a lawsuit against Facebook for allegedly infringing on 10 patents from their 1,000+ patent warehouse.

As if all of that crap Yahoo claims as their work wasn't already done on some BBS system back in the early 90's. Seriously - wipe the slate clean, and just start over.

Money Grab

March 9, 2012 16:01:24.000

The insanity of this "search engines should pay" approach should be obvious:

Germany’s government wants search engines and news aggregators to pay news publishers for using pieces of their material.

What they want is to be paid by the people who make it easier to find their material. IMHO, Google (et. al.) should just remove all covered organizations from their search results, and see how well they like that outcome.

Today we'll look at changing the default font used across all VA Smalltalk tools. To start, notice the little Aa icon at the far right of the toolbar:

Fonts

Open that, and you'll get a chooser tool for fonts. Select something you would prefer - here we are picking the Impact font. Not because it's a great choice for this, but because the change will be obvious:

After you accept the change, all the tools update. Open a few:

All of your tools now use this font.
