Destacan en número los trabajos del Coordinador Germán González y su equipo del Departamento de Educación, que desarrollarán diversos aspectos de la educación andina, además de la elaboración de material concreto para ser aplicados en escuelas rurales.
Lo destacable de esta etapas es que por primera vez se proponen innovaciones curriculares (González 1985, 1987a, 1987b y 1987c) y el diseño de libros de apresto para distintas asignaturas y niveles de enseñanza en el ámbito rural (Ahumada 1986, 1986a; González 1986a, 1986b, 1986c, 1986d, 1987c, 1988; González et al., 1989; Platero 1988a, 1988b y 1990; Molina y Gutiérrez 1988); aparecerán también estudios sobre economía andina (Álvarez 1982; Castro 1985).

Peculiar Acronyms

As we know, there several peculiar acronyms from computer science:

GNU: GNU's Not Unix

PATRICIA (tree): Practical Algorithm to Retrieve Information Coded in Alphanumeric

Software Architecture Patterns

Very interesting free ebook from O'reilly: Software Architecture Patterns

It analyzes 5 Architectures providing Pros & Cons of each one, adding good thoughts. (please, read the book, it is small enough :P ).

A summary among the different characteristics can be found at:

WebLogic Server 10.3.6 for Mac OSX

If you are trying to install WLS 10.3.6 in OS X Yosemite 10.10.5 then a couple error you may face:

1) Download generic installer; if you choose cocoa mac installer, then you'll get:

(or using system property: -Dos.name=unix  )
(or -Dos.name="OS X")
Exception in thread "chmodFile" java.lang.Error: unix is not a supported OS platform.

2) If you receive the message "Insufficient disk space!" , although you know you have enough space, the use the following parameter:

 i.e.:

java -Dspace.detection=false -Xmx1024m -jar wls1036_generic.jar


(also, a small installer window could appear, and it is from the same reason).

Books for Programming Challenges & Puzzles

This is a list of books for Programming Challenges and Puzzles. It is not exhaustive, but with the most interesting books I've found. (Evolutive List)

- Programming Challenges: The Programming Contest Training Manual
- Algorithmic Puzzles

It is not a bug


PPA: NO_PUBKEY C2518248EEA14886

I faced the following error in Ubuntu 15.04 when trying to: sudo apt-get update

GPG error: http://ppa.launchpad.net vivid Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY C2518248EEA14886
 
Googling, there are several solutions for it, but none worked.
Only a old script that is in a couple of Ubuntu forums:

http://ubuntuforums.org/archive/index.php/t-2257304.html





Script:

#!/bin/sh
# This script adds PPA keys to the primary keyring in /etc/apt/trusted.gpg

# Rather than using it, reduce your use of PPAs.

WebLogic Server XML Parsers

Many times there are question in WebLogic Server about parser factories:

java.lang.AbstractMethodError: javax.xml.parsers.DocumentBuilderFactory.setFeature

  java.lang.ClassCastException: weblogic.xml.jaxp.RegistryXMLInputFactory cannot be cast to javax.xml.stream.XMLInputFactory
    Error weblogic.xml.jaxp.RegistryXMLInputFactory cannot be cast to javax.xml.stream.XMLInputFactory

 java.lang.NoSuchMethodError: javax.xml.parsers.DocumentBuilderFactory.newInstance(Ljava/lang/String;Ljava/lang/ClassLoader;)Ljavax/xml/parsers/DocumentBuilderFactory;




Because the classpath retrieve from different parts these implemenations, including the JDK6 which bundles in it now.

This is how you can change by system properties the implementation, using xerces:

-Djavax.xml.parsers.SAXParserFactory=org.apache.xerces.jaxp.SAXParserFactoryImpl -Djavax.xml.parsers.DocumentBuilderFactory=org.apache.xerces.jaxp.DocumentBuilderFactoryImpl -Djavax.xml.parsers.SAXParser=org.apache.xerces.jaxp.SAXParserImpl

maybe you'll need to add xercesImpl.jar to your classpath.

Eclipse Platform Runtime Binary

Although, it is on the web, it is not easier to get a basic/minimal Eclipse installer.

You need to go to: http://download.eclipse.org/eclipse/downloads/
and get the desired version.

i.e.: 4.5 Luna: http://download.eclipse.org/eclipse/downloads/drops4/R-4.5-201506032000/


There you can find several basic binaries, such us, SDK, Plug-ins, SDK-RPC, etc.

The smallest is: Platform Runtime Binary

More details in each binary: http://download.eclipse.org/eclipse/downloads/drops4/R-4.5-201506032000/details.html#PlatformRuntime

Anyway, if you want this basic version to install another plug-ins, such us, Dynamic Languages Toolkit then you need to download another version (it is not sufficent with only PLatform Runtime Binary).

The domain http://www.monson-haefel.com/ seems to be lost by Monson-Haefel and for the same reason the Errata page of his bestselling J2EE Web Services http://www.monson-haefel.com/jws_errata.html

Although, it is JAX-RPC and kind of old for current days, still is a good knowledge repository.

Wonders of Numbers: Adventures in Mathematics, Mind, and Meaning

Fe de Errata

Small Errata for Hardcover First Edition of Wonders of Numbers

 
page 205, boxed equation, Chapter 89, near bottom: "c" should be superscripted

page 358, Chapter 89, 2nd line in Further Exploring: "c" should be superscripted

page 216, Chapter 95, line 3, missing upside-down F symbol. Should read "F(24)" not "(24)", where the "F" is the upside-down symbol. Similarly line 2 should read "Let's define a new function F(n)."

page 262, figure drawing error. Line segment misplaced. Figure 114.1 should have a line connecting point B to the dot directly to the the left instead of the line from the point below B to the point directly to the left.

page 374, figure drawing error. Line segment misplaced. Figure 114.1 should have a line connecting point B to the dot directly to the the left instead of the line from the point below B to the point directly to the left.
 
page 94, Equation 10 towards the bottom of the page is missing an italics "i" before the "sin".
 
page 379, it says " 9 + 9 + 999 = 1000 " should be " 9/9 + 999 = 1000 "

OC4J: org.apache.xml.dtm.ref.DTMManagerDefault cannot be cast to org.apache.xml.dtm.DTMManager

When using JDK 1.6 the following CastException may be obtained:

This is because we are using different
