vk6flab | 2 years ago | on: 55% of workers say their pay isn't keeping up with inflation
For context, inflation adjusted, in 1998 (25 years ago!) when I was a generic IT help-desk operator at a local University I was earning that rate. So, apparently in ICT we're earning too much and we should be happy about it.

I have been analysing data in one way or another pretty much my entire career. Much of the time that takes the form of writing custom code to extract data, then to clean it, then to store it, then to analyse it.I am a polyglot ICT professional and my resume is formatted as a list of work experience. As an example, for a recent large project I was contracted to analyse a large obfuscated codebase in active development.
The brief: Analyse a JavaScript library which may be subject to legal action.
As the sole developer and data analyst under contract, I determined that the library consisted of about 300k lines of obfuscated code that was in wide use and under active development. After I attempted initial static analysis, I built a tool to capture the library and log its activity whilst it was running (ie. during run-time). The library under investigation actively monitored user activity and resisted simple screen-shot attempts. The capture and logging tool I developed simulated user interaction, scrolled pages, clicked on links and logged all activity including dynamic DOM changes made by the library. The tool also captured Chrome HAR files. I used the source-code for Chrome to discover and address several messaging and logging edge-cases.
The capture and logging tool I wrote in Node.js, used Chrome and puppeteer, and was implemented on AWS EC2 using Docker images I built from scratch, published to, and pulled from AWS ECR. Logs were stored on AWS S3. I deployed the tool across random AWS regions using AWS CloudFormation and bash.
For initial analysis, I generated Graphviz maps using Python with thousands of nodes and edges showing the URL calls being used and their relationships. I conducted in-depth analysis of over a TB of logging data with customised de-obfuscation tools that I built to use abstract syntax tree filters to generate names using four letter English words to enable the tracking of function and variable names. I mapped function calls, reverse engineered and mapped (mostly undocumented) Chrome HAR files. I also traced variable values across the codebase, dynamically inserting debugging statements during run-time.
Customised versions of the library were also injected at run-time to discover further interactions of the codebase with other "cooperating" libraries. I also mapped the evolution of the library codebase itself using git, by creating commits for each discovered and de-obfuscated version. I used PHP to download historic versions of the codebase from archive.org. I traced and documented small and large changes.
I documented the entire project, under the expectation of showing evidence in court.

Email: [email protected]vk6flab | 2 years ago | on: Portugal. The Man – Official Website Is a Google Sheets Document
At one point I provided live tracking data to a popular event site using Google Sheets and advised their web team to create a local cache of the data and refresh it every 10 minutes. Instead they ignored that advice and included the document itself into the home-page. The document was hugged to death within about 30 minutes of going live on a four day event and it took days for Google to increase their throttle, at which point it didn't matter any more, since the event was over.
I realise that Google has infrastructure to handle this load, but an international event, with a (then) Google Apps account, was unable to make enough noise at Google to fix things in a timely manner.
vk6flab | 2 years ago | on: Why decline in generalists leads to disjointed games and harms tool quality
People flat-out don't believe that the skills enumerated on my resume could be held by a single person, and are.
Apparently, I'm clearly "over the hill", having been at this for nearly 40 years. I should state that I have 20+ years experience instead, as-if having life experience doesn't actually make you better qualified to understand the contexts of any role in an organisation.
My skill-set is "threatening" to others, because, apparently, knowing things about a great many technologies means that I know more than the person hiring me, which somehow means that I'm a threat. As-if surrounding yourself by people who are smarter than you is suddenly undesirable.
I've been told to "dumb down" my resume because there's too much there, even if there's 99% chance that a computer will be the device actually reading it and selecting me. Apparently I'm supposed to "infiltrate" a company at a lower level and then "show" them that I can do more, despite 40 years experience showing that people only see the skills that they want to see.
According to some automated job technologies I have 104 years of experience. Not sure how that works.
Then there are those who want to know which of the experience is "professional" and which isn't. (I've been self-employed for the past 23+ years)
In the end, I liken it to this:
"How much experience do you have in eating food?"
"Do you mean, adding together each of the 15 minute meals, or how long have I been eating food for since I was born?"
"Okay, how much professional experience do you have eating food?"

Hi I'm Onno,
I'm an experienced polyglot IT professional, software developer, trouble shooter, researcher, public speaker, educator, writer and publisher, founder and small business owner, podcaster, and licensed radio amateur. I work remotely from my home-office in Perth, Western Australia, UTC+8.
My experience with data started with the Dutch equivalent of Medicare when I was an intern, trusted with access to 20 million health records, a VAX/VMS cluster and a copy of SPSS. Since then I've built and used databases in many different contexts, from dBase (and Clipper) to MySQL (and MariaDB), from Oracle to MS-SQL, PostgreSQL and SQLite.
I've built standalone and web-based applications and lost count of how many once-off tools I've written to convert one data-set into another. I've built visualisations in R, Tableau, QuickSight, D3.js, gnuplot and Graphviz for clients around the globe. I've created mapping systems, won several Hackathons, and most recently, in a project lasting 44 months, investigated 300,000 lines of source-code, generating several terabytes of data. I'm familiar with AWS, Linux, and Open Source, am a public speaker, have produced a popular technical podcast about amateur radio for over 12 years and have conducted about 1,800 radio interviews, most of them live to air.
Whilst actively looking for the next opportunity, I'm analysing a five billion row data-set for HF Radio propagation, building a word-cloud based search engine to tag data, revising the eBooks I've published and I'm exploring how Morse code evolved to deal with the physical phenomenon of dispersion. For self-education I've been building some M/L models to classify data.
