After IDUG is before IDUG: Back from Db2 conference in Charlotte, NC

Last week the IDUG NA 2019 was held in Charlotte, NC. It featured 8 parallel tracks dedicated to Db2 for z/OS and Db2 for LUW and emerging technologies. In addition, two tracks for hands-on labs and workshops were offered. Personally, I delivered three presentations, moderated and attended sessions, and was active on Twitter. So what was on? Continue after the snap of Twitter photos from last week.

Cloud-based FIPS 140-2 Level 4 crypto service

Locks, keys, and data security
Yesterday, I got my hands on a FIPS 140-2 Level 4 cloud-based crypto service. If you are asking "what's that and what can I do with it?" you should continue to read. It is a dedicated HSM (Hardware Security Module) to manage encryption keys and offered as IBM Hyper Protect Crypto Services on IBM Cloud (HPCS). Here is what I learned while using the service.

Your chatbot with Watson Discovery News

Some months back I introduced you to a barebone news chatbot. Today, with the updated tutorial to build a database-driven chatbot in place, I want to show you how to easily combine Watson Assistant with Watson Discovery. Watson Assistant already provides steps to deploy an integrated search skill which is based on Watson Discovery. My approach is similar to the database integration: Deploy a cloud function and invoke it from the dialog.

Db2: SQL-based explain and printed acccess plan

Vote for this Db2 idea
This Friday in Munich, I gave a talk about the new native JSON functions in Db2 at the German Db2 user group (DeDUG) meeting. To speed up queries and to enforce uniqueness or some structural rules, Db2 functional indexes can be used with the new JSON_VALUE. As usual for some prototyping, I utilized a Jupyter Notebook for my presentation. Now, how to demonstrate that indexes are really used? Show the access plan! But how in a notebook?

Updated tutorial: Database-driven chatbot

If you want to build a chatbot that gets its content from a database, there is a good news. The existing tutorial “Build a database-driven Slackbot” was just updated to adapt to latest features of IBM Watson Assistant. First, define a skill that reaches out to a database service like Db2. Thereafter, use the built-in integrations to easily tie in the assistant with Slack, Facebook Messenger, embed the chatbot into your own application or use the WordPress plugin.

Running Db2 Developer-C as Docker container

Container: Db2 the easy way
Last week I wanted to start testing some new Db2 features without going through the steps of installing that Db2 version. I turned to my local Docker installation, issued a single command and had Db2 up and running. Quite interesting, that command downloaded Db2, installed it, created a sample database. Here are the details.

Db2 Developer-C Edition as Docker Image

IBM provides a free Db2 edition, Db2 Developer-C Edition. It can be installed and used as Docker container, see here the Db2 Developer-C Edition in the Docker store. Once you have added it to your basket and checked out, you can download it and get information about how to configure it. Basically, only few values need to be set in an environment file (see db2_env_list below).

After adapting the environment file, I invoke the script (with a single command) to run Db2 on docker. If not downloaded yet, it obtains the container image, starts it, sets it up:

docker run -h db2server_ --name db2server --detach \
--privileged=true \
-p 50000:50000 -p 55000:55000 \
--env-file db2_env_list \
-v /home/hloeser/progs/db2:/database \

Thereafter, I can connect to Db2 using the usual tools and SDKs.

Digital ethics, trusted AI and IBM

Last week I gave a talk followed by a discussion at a university. The presentation was about the current state of Artificial Intelligence (AI) and AI research topics. A good chunk of the discussion was dedicated to fairness, trust and digital ethics. In the following, I am sharing some of the related links.

IBM Research has a site dedicated to  AI. On that, a section provides insight into topics on what they call Trusted AI. On the main IBM site is also a portal Trusted AI for Business, providing an introduction and overview for the non-research crowd. If you are interested and want to try out and learn about few problems hands-on, I recommend these links:

IBM experts are part of many public panels, workgroups and commissions. In Germany, there is the Enquete-Kommission "K√ľnstliche Intelligenz - Gesellschaftliche Verantwortung und wirtschafliche, soziale und √∂kologische Potenziale". On the European level, it is the EU High-Level Expert Group on Artificial Intelligence.

Finally, as a showcase of current AI capabilities, I recommend this video of IBM Project Debater and the live debate at Think 2019. A short video explains how Project Debater works:

Startup lessons from a Fuckup Night

Last Wednesday, I attended the Fuckup Night Friedrichshafen Vol. II. If you don't know, Fuckup Nights is a global movement and event series dedicated to professional failures. That is, usually founders of failed startups tell their stories. Typically, it is a mix of funny adventures into the world of business, some sad parts and most importantly some lessons learned. So what were the lessons I took away? Read on...

Enterprise digitalization and cybersecurity: How companies struggle

Cybersecurity Workshop at Zeppelin University

The innovation cluster is organized by the Zeppelin University in Friedrichshafen. It tries to bring together companies from the wider Lake Constance region that are impacted by digitalization. The researchers have identified four topics that will be addressed:

Hello again, Davos, AI ethics, cybersecurity, Db2 events and IBM Cloud

Hello, here I am again after a while. I hope you had a good start into 2019. I enjoyed being offline for a while, then got busy with not much time to blog. So, here is a roundup of things going on.
