nohup allows me to run jobs on my servers and have them keep running even when I log off.

I’ll give you a few examples, but that’s no substitute for the docs! https://www.freebsd.org/cgi/man.cgi?nohup or just run man nohup

# for example, run my script.py even if I lose connectionnohup script.py
# but let's say I want to have my terminal back after running itnohup script.py &
# but my favorite is getting all the output and getting the pid!nohup script.py > script.out 2>&1 echo $! > script.pid

If you’re a control freak who has a compulsion to understand every piece of how the world works you’ve probably tried to “do it yourself”… and so this piece is part installation guide, part diary entry, and part a warning:

Abandon all hope ye who enter here *

*unless you hope to learn a whole bunch

Step 1: Download

At https://www.python.org/ download the installers for both Python 3 and Python 2. If you are only going to pick one Python 3 is the way of the future. Unless you know what you’re doing go with the default configurations.

This step is all most…

My first developer talk in the books!

You can see the recording yourself at this link, or get the presentation and all the materials here unofficialoraclecloudhub.github.io/oracledb-graphql-demo/

This site (hosted from out unofficial cloud-hub GitHub repository) has all the materials I presented in my talk. The GitHub repo that has the code for the site also has everything you need to run the modified GraphsiQL app on a real Oracle Database yourself!

Building it

Not a trivial task.

I was hoping to have the demo done three weeks before hand (before Q4 really picked up) but a last-minute trip to San Fransisco to record at Oracle Studios and two HUGE…

I loved this course! Chris Saxon has so much energy and enthusiasm for databases, it’s infectious. This is a very basic introduction to RDBS and is appropriate for anyone :) Chris also has a fantastic youtube channel — see the intro to the course here

This covers introductory PL/SQL — which might be different from the SQL you’re used to!

Misadventures in automation

TL;DR — if you’re using chrome visit chrome://net-internals/

By day, I work behind an http proxy. By night, I tinker without restraint- feeling the open internet breeze through my hair.

While I’ve adapted by writing a script to set/unset proxy settings it would be nice if there was a program that would just run in the background, looking for network changes, and alter setting accordingly. I also want to learn java, and the best way to learn is to do, so hence my new pet project…

I wanted this program to be cross-platform compatible but that was…

Would you trade privacy for convenience?

The other day I wanted to take a stroll down memory lane, but couldn’t seem to coordinate the right songs, photos, and diary entries… We accumulate so many memories (see cute baby below) distributed across a collection of devices. There’s no single interface to reach them, you can’t search them, a lot of times it even means physically activating hardware! This is 2017!!! I should be able to do this without getting out of bed!

Yes, there are some pretty great solutions. Google’s G Suite in combination with Google Photos comes pretty close to…

I was creating a new BDC (Big Data Cloud) instance when everything was not going smoothly, as usual... the storage container now had to be in global format! This means I need the URL for Oracle Cloud’s Storage REST API.

We need two things; the Cloud Storage Container Name and then the REST Endpoint.

Cloud Storage Container Name

This you should remember, you named it! Mine is “on-fire”.
