who we are

Jonni Bidwell Using an LCD display (the original Display-o-Tron 3000) connected to an OG Raspberry Pi, I managed to create an audio spectrum visualiser, which got its data from another Pi playing from Volumio. It only managed to update about every 0.2s, but it was my first client/server program and I am still proud. Nick Peers I’ve built a fair few PCs over the years, but none have proved as satisfying as my current build: an AMD Ryzen 7 2700X with 32GB RAM and 256GB Samsung NVMe SSD. It’s blisteringly fast, and perfect for everything I’ve thrown at it so far. Les Pounder My proudest tech achievement is a fortune teller, located in a Blackpool arcade, which uses Python to tell you your future. Tickets for the gift shop and a tarot card are spat…

build it yourself

Projects, projects, projects! From the Raspberry Pi to Linux to Arduino, we’re going to keep you busy in 2020 with only the best maker projects to try in Linux Format! We’re running a maker special with our favourite builds to try, from running an NAS to a fully functional robot build. I’m currently renovating a house – largely by myself – which is fun. I get to play with lots of different tools, work with wood, plaster a wall, do a bit of soldering, break a few things, fix a few things and get a sense of achievement when a room finally doesn’t look like it’s come straight out of Fallout 3. Now, I’m quite often wrong (just ask Jonni) but I get a strong feeling that open source and Linux people…

tightening internet security in 2020

It looks like there are some big changes afoot for the internet in 2020, most of which will be welcome to anyone concerned about their online security and privacy. First of all, LibreDNS ( ) has now launched, offering “a public encrypted DNS service that people can use to maintain secrecy of their DNS traffic, but also circumvent censorship.” The DNS has been created by a group known as LibreOps ( On its GitHub page the group claims it is “a group of hackers (re-)decentralizing the net. Doing our part.” That ‘part’ includes creating “decentralized services and tools that respect users’ privacy by default.” As well as offering a DNS service, LibreOps has also created Diaspora ( ), a distributed social network, Etherpad (, an open source online editor for collaborative…

mozilla lays off 70 people

It seems that Mozilla is having a tough time at the moment, with news that the company behind the Firefox web browser has laid off 70 people – a considerable amount considering it employs around 1,000 people worldwide. Back in 2018, Mozilla generated $429 million from deals with search engines. Companies like Google, Yahoo and Yandex pay Mozilla to have their search engines included as the default search engine in Firefox. Mozilla had been hoping to reduce the dependency on these deals, which accounts for around 90% of the company’s revenue, because Firefox’s market share continues to fall and those deals could become less lucrative in the future. The company had planned to bolster its revenue with subscription services, such as the Firefox Private Network service ( and other products including file…

torvalds: don’t use zfs

Linus Torvalds, the somewhat outspoken (we hadn’t noticed – Ed) creator of Linux, has taken to a mailing list ( to moan about the ZFS filesystem, saying, “Don’t use ZFS. It’s that simple. It was always more of a buzzword than anything else, I feel, and the licensing issues just make it a nonstarter for me.” The licencing issues Torvalds is referring to is the fact that ZFS uses Common Development and Distribution License (CDDL) 1.0, while the Linux kernel is licensed under the GNU General Public License (GPL) 2.0 – and these are not fully compatible with each other. If ZFS is included with the Linux kernel, this would mean that it is a derivative work of the original Linux kernel. What seems to be particularly troubling for Torvalds is Oracle’s…

silent runnings

“Recently we had a lovely email, which hopefully you’ll have the pleasure of reading next issue, from a computing veteran. He talked about the revolutionary innovations he had seen over the course of his career, from punchcards to personal computers, and wondered why we don’t see such revolutions anymore. CPU clock speeds and misrepresentations of Moore’s law are commonly used to support this argument (our dear reader did not use these and that is why we like him). This got me to thinking, are all improvements really incremental now, or do they just seem that way? Let’s take Linux as a sort of microcosm here. Linux journalists would dearly love if every new release of a distro was packed with revolutionary and shiny features, but these days we often have to…
