Exploring CockroachDB with ipython-sql aka sqlmagic and Jupyter Notebook


Today, I will demonstrate how ipython-sql can be leveraged in querying CockroachDB. This will require a secure instance of CockroachDB
for the reasons I will explain below. Running a secure docker-compose instance of CRDB is beyond the scope of this tutorial. Instead,
I will publish everything you need to get through the tutorial in my repo, including the Jupyter Notebook. You may also use CRDB
docs to stand up a secure instance and change the url in the notebook to follow along.

Vista Vulnerability Report mentions Ubuntu 6.06 LTS

Update: I posted this on MIXX since DIGG was taken care of by someone already, except that that user didn't really write a good preview for it so it got buried. This report is generating some buzz though. I emailed this report to Mark Shuttleworth of Ubuntu fame and little did I know, HE ANSWERED!!!! Whoever answered me on that side of the e-mail pipe liked the report and was wondering if it was official and whether he could quote from it. It definitely is official and I forwarded him the e-mail with this report, he said he will pass it down internally. That made my day, it's amazing that a man of his statute, that's if it was him, answers e-mails from regular people like me. That's what I call a real genuine pioneer! Thank you Mark and all of the Ubuntu Staff. Read

Running CockroachDB with Docker Compose and Minio, Part 2

This is my second post on creating a multi-service architecture with docker-compose. This is meant to be a learning exercise and typically docker-compose is used to set up a local development environment rather than a production-ready set up. I regularly, find myself building these environments to reproduce customer bugs. For a production-specific application, refer to your platform vendor documentation. At some later time, I will cover Kubernetes deployments that can be used as a stepping stone for a real-world application. Until then, let's focus on the task at hand. We're building a microservice architecture with CockroachDB writing changes in real-time to an S3 bucket in JSON format. S3 bucket is served by a service called Minio. It can act like an S3 appliance on premise or serve as a local gateway to your cloud storage. Let's dig in:

VirtualBox options to start VM in Normal, Detached and Headless Modes

Image
I've been an avid user of VirtualBox for a long time! Much of what I've learned in my career had something to do with VirtualBox. I do all my testing and new tutorials in VirtualBox, I use Hortonworks Sandbox VirtualBox image for my work. This is probably not a new feature but it is definitely new to me because I just noticed it, VirtualBox has an option to run in different modes, at least from the GUI perspective. I know there's a lot of untapped potential in using the VBox CLI but I haven't had much need for it yet. Back to the topic, you can now launch your VMs in headless and detached modes right from the GUI! Usually, when I launch a VM in normal way, the VM window just hangs there and is pretty annoying. I prefer to SSH to a running VM from a console instead of using the VM window. Now I can launch a VM in headless mode and it's business as usual. No extra windows, and I bet the memory toll on my machine is also smaller. When you click on start your VM, you no...
