What's amusing is that I specifically made a comedy license for it, because I thought trying to protect the IP of such a thing is madness in the AI-native era. Then within days I find out it's a massively funded startup!
I'm a very strong Concourse proponent. We've been using it exclusively for three years, and it's better than anything we've experienced that our customers use (I run a consultancy).
We run Concourse London User Group, and the first few instances were like some kind of Jenkins survivor's support group.
It also makes things more comfortable - you can stretch and change position on long drives. In three hours of motorway driving on Sunday, I was only driving for about three minutes - the rest was Autopilot.
I drove from the UK to Ålesund, Norway and back in a Model X, which was about 1,300 miles in each direction. Did it on the way home with two kids in the back.
If you can accurately estimate how long a software task will take, you should have already made a reusable component or automation to generate that code.
Estimates are meaningless. I've seen PhDs waste endless hours faffing with estimate-calculating spreadsheets.
Fundamentally, the universe is unpredictable. Chaotic and complex systems require their starting conditions to be measured to an infinite level of precision to be predictable. The Heisenberg principle means this is, as far as physics can tell, impossible.
On a more practical macro level, a complex adaptive system becomes unpredictable once three feedback loops are present (the three body problem is related).
Modern computer systems are unpredictable because we cannot predict the interplay between levels of abstraction.
It does not matter how smart you are. Unless you have perfect knowledge of all levels of abstraction in the system below you, even in a macroscopic sense you cannot predict the future. Precise estimates will be inaccurate.
Confidence ranges and superprobabilities are of some use. Discrete and precise estimates are an utter waste of time at best, and are dangerous and misleading at worst.
EDIT
Written on a mobile waiting for plane take-off, hence lack of citations. For more on complex adaptive systems, I recommend the works of Murray Gell-Mann and the research output of the Santa Fe Institute, particularly Scott E. Page.
If you're getting burnout doing agile, you're doing agile wrong.
Don't do sprints. Have a continuous backlog. Don't do overtime. Don't make estimates. Always do the simplest thing. Only ever do the most important thing, as defined by the stakeholder.
I've written and talked about this at great length. The fact people suggest agile gives you burnout reinforces my experience that Scrum is largely misinterpreted and people incorrectly focus on sprint commitments. If Scrum is so commonly misinterpreted, it is flawed.
I saw these folks at AfrotechFest[1] in London last year, which one of my colleagues helped organise, talking about their entrepreneurial experience. Really great to see them getting mainstream media coverage, and I wish them all the best. The idea of getting into a van full of blades with strangers was definitely joked about on stage, and if they can salve that concern then they must be doing a good job!
Yeah, accept those writes and favour availability. Customer was a wealth management company.
Imagine a customer has £100 in their account. System partitions. Customer withdraws £70, hitting one DC. Customer then hits the second DC, this time withdrawing £50. Each DC thinks the transaction is valid, and so serves it.
Later when the partition is restored, events are played back, and divergent history is detected via the vector clocks - the two withdrawals are not causally related. Remediative action can then be taken.
Transactions prevent bad things happening, but require CP semantics. Eventual consistency allows AP, allows bad things to happen, meaning you have to be able to detect them and clean them up later.

I've got Claude Code adding Gemini and OpenCode support to my tool currently.
