How to setup a GUI via VNC for your Oracle Linux Compute Instance in Oracle Cloud Infrastructure (OCI)

In a couple previous posts, I explained how to get an “Always Free” Oracle Cloud compute instance and how to install MySQL on it – as well as how to add a web server.

I started my IT career (way back in 1989) using a (dumb) terminal and a 2400-baud modem to access a server. While I still use a terminal window and the command-line, it is always nice to have access to a GUI. In this post, I will show you how to install and use a GUI on your Oracle Cloud …

In a previous post, I explained how you can take advantage of Oracle’s “Always Free” Cloud instance to obtain a free Oracle Cloud compute instance (virtual machine) and install a copy of MySQL – without having to pay a setup fee and without incurring any monthly charges. And, you can have two free compute instances per account.

This free Cloud option from Oracle is great. I can think of a lot of ways to utilize a free Oracle Cloud compute instance – but the first one that came to …

Installing MySQL on Oracle Cloud’s “Always Free” Compute Instance

At Oracle’s OpenWorld 2019, Oracle announced an Oracle Cloud Free Tier, which includes Oracle Cloud services that will always be free – as long as you use them or keep them active.

Most other hyperscale cloud vendors offer a free 12-month trial before they start charging you, so to see Oracle provide a “truly free” service is really great. And the free services are not just limited to one or two choices – you get a wide variety of free services to choose from. As of this blog post, here is a brief summary of free services (these are subject to change in the future):

The Slow Software Movement

Those who build SaaS know that you’re actually providing an experience. You’re building long-term relationships and aiming for recurring revenue. Therefore, your product must be flexible, resilient, and consistent.

Many companies find it hard to take time, acquire the right ingredients, and design truly great software from the bottom-up. This is understandable given how fast the SaaS industry moves.

But firstly, who am I to be talking about this subject? My education was in Economics and Complex Systems, and I’ve been fortunate to gain exposure to various IT trends and tools working almost a decade mostly in Tech. I started interviewing customers at Continuent (majority SaaS) over five years ago, and I have listened to a number of …

NoSQL + SQL = MySQL 8; Keynote OSI2019

NoSQL + SQL = Mysql 8 Open Source India 2019 keynote from Sanjay Manwani

Slides from the keynote presented at Open Source India 2019 at Nimhans convention center Bangalore. As usual lots of interesting folks. Lots of focus on Open Source.

Met people from the SODA foundation who are trying to standardize the IO layer across all cloud implementations. All the best guys.

Also met folks from MOSIP who have an effort ongoing to help countries create their own UID. Seems like they already have some traction.

Also met an interesting person trying to think about Indian design and creativity in software. After Chumbak it does make sense to think about how not only UI but the software development …

How free is your Open Source software…really?

With growing development and support costs as well as the need to maintain a sustainable business, it became apparent that maintaining the OSS release of Tungsten Replicator (TR) just wasn’t viable. Earlier this year we decided to close it down, instead focusing our efforts on improving and developing its commercial release whilst also growing our flagship commercial product, Tungsten Clustering.

For many businesses, Open Source Software (OSS) is still a very viable solution in many use cases, and I’m sure it will continue to be so for a long time, but I wanted to explore whether an OSS solution really is as free as the $0 price tag suggests.  In this blog I explore just that..

The hidden costs of OSS

Over the last few weeks I stumbled …
