Linux Desktop at work
So far my only experience of using Linux in a work desktop environment, was a very positive one.
This was a few years ago now, I was working in a UK government office (as a consultant), along with a small team of Java developers (also from the same consultancy). Can't say which uk gov department, or any specifics of what we were delivering.
We'd been brought in to do some software development, specifically Java, I was acting as lead dev/designer (plus help with things like building local scripted/automated test environments for unit testing).
When we got there, we were supplied with client provided laptops (nothing unusual there), but it turned out these all had Ubuntu installed, which was a first for us!
I was already familiar with Linux myself, I'd used various flavours at home for years (including Ubuntu), desktop, servers, header-less etc, and I'd cut my teeth on AIX boxes years earlier, so this was a pleasant surprise for me. But it turned out no one else on our team had ever touched Linux desktop before, or even command line on servers etc. (We were almost entirely Windows back then, including servers).
But it seems the client had pushed adoption of Open Source. So all Laptops and servers were Linux, all tooling (build/deploy/manage etc) was OSS, although they did still use Outlook for email (this MS usage was gov wide, whereas OSS was specific to just this department). Outlook etc was via the web versions.
I became the defaco Linux SME for the team, and walked them through the differences compared to Windows etc. (It's also how I ended up doing all the automation side of things, as I was already familiar with things like shell scripting etc).
Within a few days, the whole team had adapted to using Linux, with the devs realising that many of the tools they'd used via a bit of a cludge under Windows, were just native under Linux. Even the IDE the team used (one of the Eclipse based ones) was also Linux native, so no learning curve there.
About 6 months later, when the project came to a close, the team were actually sad to see their Linux laptops having to go back!
This is so far, unfortunately, my only experience of Linux desktop in a professional environment, in over two and a half decades!
