TeamMentor TBot page to delete articles based on list of Guids

Continuing on the thread where I'm helping Serge to prune the TeamMentor's ASP.NET 3.5 library (see here, here and here for how I set-up the current test environment), one of his requirements was to be able to batch delete TeamMentor articles based on a list of GUIDs.

Without touching the 3.4 codebase I was able to add a new TBot Admin page with this feature (which is quite a cool 3.4 TeamMentor capability that I will blog about in a different post).

As with the previous examples, the TBot Script, called Delete_Articles_By_Guid.cshtml was developed on a GitHub hosted, TeamMentor UserData Repo:

Eclipse Plugin that allows the execution of REPL Groovy Scripts (in the current Eclipse Instance) and Fluent API for Eclipse+SWT

For the past 6 months I have been working on an Eclipse plugin that implements a Groovy REPL that makes it very easy to learn Eclipse and SWT.

I also started the creation of a fluent API for Eclipse and SWT, in order to reduce the amount of code that needs to be written when creating Eclipse plugins.

The plan is to release the next version of this plugin as an kind of Eclipse Plugin Builder, but it is already quite usable in the current state.

Setting up a Minecraft server in Azure (for use at weekly CodeClub session)

For almost one year, I've been doing a weekly CodeClub session at one of my kids schools, and sometimes at a local restaurant (see here)

Since there is quite a lot of passion in the kids for Minecraft, I decided that for this term, we would try to use a Minecraft server in class, and see if we (me and kids) can figure out how to use Minecraft without a mouse (ie, with only programming).

Since my first experiments with a Minecraft server where quite positive (see Setting up a CraftBukkit based Minecraft server on OSX (Nov 2013)) I decided that it was time to take it up a notch, and try to create a Minecraft server in Azure (so that the kids can access it from home).

Here are the steps I took:

Adding files to TeamMentor's web root via a UserData folder (synced with GitHub)

This post shows how to add custom files to the TeamMentor's webroot using a special feature of the TeamMentor's UserData folder.

In this demo I'm going to use the UserData setup in this post (currently synchronised with a GitHub repo)

Basically we are going to edit a file in GitHub, which will end up in the root of the associated TeamMentor website (which is quite a powerful PoC and bug fixing feature).

First step is to go to the synced GitHub repo (created here) and click the Create a new file here button in GitHub's UI:

Using TeamMentor 3.4 TBot admin pages to load and sync UserData with a GitHub hosted repo

Continuing from where Using TeamMentor 3.4 TBot admin pages to load and sync a Library hosted on GitHub left, this post shows how to use the same technique to sync TeamMentor's UserData with a GitHub repo.

For more details on how the UserData repo/folder fits within TeamMentor's architecture, see these posts:

Using TeamMentor 3.4 TBot admin pages to load and sync a Library hosted on GitHub

Serge asked me to help making some changes to the TeamMentor's Asp.NET 3.5 library, and since we need a test server to look at what might be changed (and run some scripts) this is a good time to show about how to use the TeamMentor's 3.4 Tbot pages to load a Library hosted on GitHub

I will also show, how once the TM server is configured with a library using a Git url,  changes can be auto committed/pushed to that Git server, every-time there is a content edition using TM's web editors.

Step 1: Preparing the target TM server

Lets start with an Azure hosted TeamMentor server, for example this one:

Viewing Eclipse and SWT objects (Workbench, Display and Shell) using Groovy's ObjectBrowser and using TeamMentor's Plugin ObjectBrowser

Using the Groovy REPL included in TeamMentor's Eclipse Plugin (see update site and more info here, here, and here) it is possible to view in real time a number of Eclipse/SWT objects (for example the Workbench, Display or Shell )

Using Groovy's ObjectBrowser:

Let's start with Groovy's ObjectBrowser which I used to use just about every day, since it gave me access to a live view of an particular Object's Fields, Properties (from getters) and Methods.

Eclipse Groovy REPL - Open TeamMentor Article in multiple formats

Part of the new TeamMentor Fortify Eclipse plugin v1.6.0 (update site here, installation instructions here) is a really powerful TeamMentor and Eclipse API which can be easily accessed via the included Groovy REPL.

In this first post (of several in this topic) I will show how to use the APIs to Open TeamMentor Article in multiple formats


The first step is to open the Util - Write Script (TeamMentor DSL) view (which is the name of the provided Groovy REPL) using the TeamMentor menu (note that the Advanced mode features config property needs to be checked, or the Advanced and Debug Features sub-menu will not be visible):

Fixing Coding Signing issue where Eclipse Plugin didn't install in Indigo

As mentioned in the Saga to sign an eclipse plugin with a code cert the problems didn't finish after the plugin was signed OK.

During the final QA stage Roman reported that he was Unable to install plugin on Indigo.

I was able to replicate that issue on a clean install of Indigo, where I got the following error when trying to install the TeamMentor Plugin:

Saga to sign an eclipse plugin with a code cert

Signing an Eclipse Plugin with a code cert should be simple right?

Well this is probably one of those cases that maybe it is obvious for others with more knowledge on how java code signing works, but I've spend the good part of two days trying to sign an eclipse plugin, and finally I was able to get it to work.

I will start with the solution (as executed in OSX), and then talk about the problem:

Book: Sum: Tales from the Afterlives

I just finished reading Sum: Tales from the Afterlives by David-Eagleman, which is a small and easy to read book with lots of great ideas and concepts.

The books is basically 40 mini sci-fi stories about possible scenarios that could happen after we die.

Ironically, and predictably, the side effort of reading these possible scenarios, is to appreciate even more the live we currently live on :)

David is also the author of  Incognito: The Secret Lives of The Brain, which is a book that I started reading on a Kindle, loved it, but never finished. This is another good example of why Kindle/eBooks don't have the same connection with the reader as physical book (see Physical Books are the best technology for reading for a better analysis of why I think that happens).

I have now bought a physical copy of  The Secret Lives of The Brain  and am looking forward to reading it property :)

Lockhart's Mathmatician's Lament, Math's should be treated as Art and the 'dangerous idea' that Zero is

I have a problem with how maths is being taught to our kids.

The best description of the problem I've read is Lockhart's Mathmatician's Lament since it really touches on the fundamental problem that we (as a society) have created:

Maths should be taught as Art, just like Music or Painting , instead of the current 'force feed abstract non-real-work complex set of instructions and concepts'

If you have not read his amazing paper (and you can just start with the first 10 or so pages), do it NOW since it might change how to think about Maths and how they are taught in school.

Updating GitHub Forks with latest commits from GitHub's 'parent' repo

One of the areas that tend to case some problems with GitHub 'Forking model' workflow, is the need to have the Forks updated with the commits that have been added to the Parent repo (i.e. the repo that was used to create the Fork from).

To see real-word examples (and pains) of this issue, take a look at these posts:

• How to update a forked GitHub repo (in this case tm-sme/Lib_Vulnerabilities) 
• Syncing all releases to the same commit and Tag (for TeamMentor v3.4) 
• Fixing the Merge conflict caused by one extra commit on TeamMentor master 

For the example show below, I'm going to update the DinisCruz-Dev/TeamMentor_Eclipse_Plugin repo which is a Fork of TeamMentor/TeamMentor_Eclipse_Plugin (here also referenced as the Parent repo).

Updating the GitHub repos for the 1.6.0 release of the Eclipse Fortify Plugin

As you can see by the recent eclipse related posts, I have been working on a Plugin for Eclipse that shows TeamMentor guidance to users that have access to the Fortify Eclipse plugin (and *.fpr files). We are now in the final stages of releasing the first public version (1.6.0) which is actually made of two parts: An Eclipse Plugin builder (which is Open Source) and a small 'Fortify Specific' code-mapping script. Very soon these will be in separate projects, but for now they are all hosted at the TeamMentor/TeamMentor_Eclipse_Plugin.

This post is just to document the current GitHub development model and where to find the main parts of this release.

On Java code formatting

As a variation of what I wrote in Formatting code for readability here is another example.

Which 'Java source equivalent files' shown below are easier to read?

This one (from FAQ How do I open an editor on something that is not a file?):

How to update a forked GitHub repo (in this case tm-sme/Lib_Vulnerabilities)

Today I helped to update the tm-sme/Lib_Vulnerabilities repo which is a fork of the TMContent/Lib_Vulnerabilities and is being auto-updated in real-time when changes made to the https://sme.teammentor.net/ server (i.e every time there is a content change in https://sme.teammentor.net there is a server-side git commit, followed by a git pull to tm-sme/Lib_Vulnerabilities (which is a pretty sweet workflow))

The issue we had was how to push the changes from tm-sme/Lib_Vulnerabilities into the TMContent/Lib_Vulnerabilities  repo, so that they can be synced back to https://vulnerabilities.teammentor.net

Note: this workflow would had been easier if the two repos where in sync, but it happened that there was one commit made to TMContent/Lib_Vulnerabilities (which is the master repo) on the 13th of Dec (d26f385) in between a bunch of updates to the tm-sme/Lib_Vulnerabilities repo (done automatically by TeamMentor). Bottom line: at this stage the repos are not compatible, which is why the GitHub Pull Requests don't work.

The O2 Platform is like a Microscope

Dennis Groove gave a really nice answer today on how he views the O2 Platform: "...O2 is in my humble opinion a tool not dissimilar from a microscope, it allows you to see what can not be seen. So yes, it does allow you to identify security vulnerabilities via static analysis and other methods. However, that is not really using the tool to its full potential..."

Here is the question asked on the O2 Platform mailing list:
