Latest LLM-based reasoning models hallucinate up to 79% of the time, per @nytimes.

For devs, that’s not innovation—it’s risk.

Diffblue Cover is different:
✅ Built on reinforcement learning
✅ Tests that compile & run
✅ Trustworthy by design

Hard to believe it's been 20 yrs!

[Jono Bacon @jonobacon]

Wow, 20 years ago @Canonical sprung into life...and it completely changed my own life.

While I didn't join in 2004, I came along a few years later...Canonical captured the interest of the early British open source community with @ubuntu .

At the time I was a journalist, writing for @linuxformat, @linuxmagazine, Linux User & Developer and others...and I was building a community in the UK called Linux UK.

These were the earlier days of the commercialization of Linux...and we all hankered for the same thing: a distro focused on (1) simplicity and ease of use, (2) technical brilliance, and (3) a strong commitment to community and building something great together.

Back then, most distros had some of either but none had all three...and then Ubuntu came along (in brown).

I instantly became a fan. It was early, it was ugly, but it innovated...and it innovated with a cheeky smily for trying something new. I was hooked.

I could see the huge potential, and I wanted to be part of it.

I had gotten to know @sabdfl a little via some events and I had heard he was hiring for an 'Ubuntu Community Manager'. I had never seen a 'community manager' job before.

I emailed him to feel out whether I might be a fit and he said, "I am not sure if this is the right job for you". Maybe he was right? 🤣

...but I knew in my gut that I could do it...I just needed him to give me a shot.

A few months later after a series of discussions...he offered me the job...and the ride of a lifetime started.

We built a community of millions of users, hundreds of thousands of developers, docs writers, translators, event organizers, and more...all over the world.

The job took me across Europe, the Americas, Asia, and beyond...and I met truly inspiring people from all walks of life.

Our community did AMAZING things: packaging thousands of applications, building a whole set of apps for Ubuntu Phone, translating Ubuntu into hundreds of languages, running a global network of local user groups, working closely with our friends in Debian and upstream projects every single day...it was awe-inspiring.

My job was simple: streamline how good people build great things, keep them motivated, solve their problems, and tell their stories.

I am tremendously proud of the community we built around Canonical, and I had an amazing team of people including @mhall119, @castrojo, Daniel Holbach, Nick Skaggs, @popey, and others...

...but what made Ubuntu so special in my time there was the genuine sense of connection we had with our community.

We were like a family...we loved each other...but we would argue...but EVERY time we debated or disagreed it was from a position of respect and finding common ground.

Even when I wrote an April Fools post saying our biggest critic was fake and I was pretending to be him all along (trololol)...he took it in the spirit it was intended...and that to me underlined a mutual respect within each other (even in the thick of fierce disagreements.)

But more personally, I have huge thanks to @sabdfl and @silbs for giving me a shot. It changed me life in a number of different ways, and I will always be grateful.

Here's to Ubuntu...here's to Canonical...and here's to the freedom to move the damn window buttons to the other side. 🤘

What is the ideal level of code coverage for unit testing in #Java applications? Atlassian recommends 80%, whereas the standard at companies like Google seems to be “60% as acceptable, 75% as commendable, and 90% as exemplary.” Read on ➡️

The tech industry is broken and the system is stacked against start-ups trying to push it in a better direction. So we’re going to invest in those companies ourselves.

@jakeriley @NYTimesWordplay That's happened to me before. There's a bug in the android app that doesn't clear the previous day's data completely.
