Guidance on a More Effective Approach to Your Project and Coding
— by Hawke Robinson — last modified Mar 12, 2023 03:04 PMThis posting is about some very basic, but FUNDAMENTAL, steps that should be taken with every project at all levels. Taking short cuts on these basics "passes the buck" down to others and is very inconsiderate of everyone that comes after you, so please make this a basic habit for everything you do, if not for yourself, then for everyone else that has to look at your project or code later (you won't be around forever).

ERPNext Self-hosted on Debian 11 Bullseye
— by Hawke Robinson — last modified Jun 05, 2022 09:38 AMERPNext technically is better supported on Debian 10, but since that is getting a bit old in support I'm trying to make it work on Debian 11 so I can remain on there as long as possible, this does mean some tweaks have to be performed to get it all working and dialed in. This page summarizes the tweaks I have found, and will be updated periodically as new ones come up.
Odoo has become too Mercenary. Abandoning Odoo and evaluating alternative replacement options. - Trying ERPNext
— by Hawke Robinson — last modified May 19, 2022 03:32 PMUnfortunately the opensource community in the last 10 years is killing the goose that laid the golden egg. The new generation of coders who don't know what it was like before opensource, are shooting themselves in the foot by becoming increasingly mercenary in their opensource approach. We saw this with Plone, and now with Odoo. So now we need to find another alternative, one again.
Old Technology Grognard's Opinion Piece On Current Hype About Blockchain Buzzword Bingo
— by Hawke Robinson — last modified May 13, 2022 09:10 AMI've been involved with computer/information technology since 1979, and online since the same time. This is just a quick response to an email conversation I had with someone, that I thought might be worth capturing here. Much of what I state is arguable, so take it as the opinion piece that it is, rather than the more instructional pieces I usually write. Cheers!
Our Top and Ongoing Woes with Odoo

It meets our needs for our various small companies, but there is significant pain associated. Unfortunately we haven't found a better fit over all these years to the feature set we need. Here is a list of the challenges/problems we keep running into spanning Odoo versions 11 through 15 and ongoing...

The Fifth AND Second Age of Computing?

Jitsi Architecture Variants
— by Hawke Robinson — last modified Jul 13, 2021 08:01 AMDue to Jitsi’s modular, opensource, and highly configurable nature, there are many different architecture variations available when deploying a Jitsi ecosystem. This posting attempts to summarize, some more theoretical for the sake of discussion and analysis, a wide range of variants to consider for different implementations. Which Jitsi Architecture Variant to choose is based on each individual's specific scope and budget. Each successive variation tends to be more complicated than the prior variant. Note that these are NOT Jitsi official variations or terminology. These variation distinctions were created by Hawke Robinson as an attempt to bring some order to the many different potential approaches, and increase clarity when considering scalability, features, and budget constraints.

Critical Thinking About Microservices vs. Bandwagoneering - The Latest Buzzword Bingo: Microservices, Containerization, etc.
— by Hawke Robinson — last modified Nov 23, 2021 01:18 PMEvery profession is rife with buzzwords, and tech is replete with them. The specific details change, though the basics remain the same, and often recycle old-as-new every 20 years or so. This posting discusses the current bandwagon buzzwords about old-is-new microservices and monoliths primarily, though with some ancillary mentions regarding containerization, and more on Jitsi.
Trying to run multiple selenium 3 chrome driver nodes per AWS spot instance: goal 5k users minimum
— by Hawke Robinson — last modified Jun 03, 2021 04:11 AMI am tasked with extensive load testing of Jitsi and related components. There have been a number of challenges just getting the tests to work on the scale needed (minimum 5k users, preferably 20k, but that can be extrapolated from the 5k). But just trying to get to 5k continues to be a challenge due being back in the 1970s and the popularity of "the cloud". I once again have to deal with the equivalent of the IBM engineers and begging for resource access to do my job... Anyway, here are updates on how it is going...

At 2,000 and climbing! [SOLVED] Standalone all-in-one Jitsi server max capacity 600 users, no matter how much hardware (at least in AWS)
— by Hawke Robinson — last modified Oct 28, 2021 11:10 AMI am working on a very extensive load-testing for capacity planning project analyzing Jitsi and various related components in educational and other settings, for my current employer. In the current load-testing I have hit a hard limit around 600-650 users for a default-install standalone all-in-one Jitsi server. This is not expected behavior. I am hoping the JItsi community can help determine if it is as simple as a configuration tweak, or if it is a more serious bug.
