Pine64 stops making Linux devices as AI inflates component costs

If you've been eyeing up one of PINE64's Linux-friendly single-board computers, phones or tablets, now would be a good time to buy one. The open-hardware company has announced it will not be "producing more Linux devices" for the time being, and expects its existing stock of certain devices, including the PineNote and PineTab 2, to sell out in the next three months. After that, there won't be more until. Why's the company pulling the plug on production? One guess: RAMaggeddon. The AI infrastructure boom continues apace, and demand for memory and storage chips has reduced supply and driven up costs [...]

Firefox 154 released with translation, AI and UI tweaks

Mozilla has released Firefox 154 with some small AI-related changes, an 'improved' full-page translations and faster video seeking on "all operating systems". Firefox 154 serves as the final monthly release of Firefox before browser switches to a faster, twice-monthly release schedule early September. That means you'll be back here, reading "Firefox 155 released" in a couple weeks, rather than the usual four weeks. But enough what's coming; what's new now? Firefox 154's main changes Firefox's been expanding its range of address bar actions in recent releases. We got tab muting action in v152 and an colour picker in v153. Firefox [...]

Ubuntu's App Center doesn't know what went wrong

I recently re-encountered my favourite 'error' dialog in Ubuntu, which is thrown by the distro's App Center (snap-store), which is the default GUI software management tool. Now, I don't see it often, but when I do it (un)helpfully informs me: "Something went wrong. We're sorry, but we're not sure what the error is." I appreciate its honesty and sympathise with the general sense of unease it imparts – I say something similar myself, looking at the state of the world – but surely it's the software's job to know what's wrong – or at least pretend it does! Here's the [...]

Wordbook is a modern offline dictionary for GNOME

They say never judge a book by its cover, and few do if said book is a dictionary, but what about desktop dictionary apps? I recently came across Wordbook, a modern English-English dictionary powered by OpenEnglish WordNet and eSpeak for pronunciations. Wordbook is in GNOME Circle, and its GTK4/libadwaita UI is a good fit for the desktop. Wordbook uses a lexical database, with words grouped into 'synsets' based on their meaning. It makes it easier to explore related words, distinguish between words that look similar (but have different meanings) and find different precise alternatives. A random word option, favourites and [...]

Linux 7.2 brings cache-aware scheduling, faster ext4 and Btrfs

Linux kernel 7.2 has been released, adding cache-aware scheduling, ext4 filesystem performance boosts and a slew of new and improved hardware drivers for laptops and peripherals. A merge widow record was also set during the 9-week development cycle, with more than 2,100 individual contributors involved. AI, obviously, has helped. Commit-crunching by LWN found roughly 5% of commits in 7.2 have an 'assisted-by' tag, indicating AI usage. Not that the latest kernel update was all additions. More than 13,000 lines of code for legacy i486 CPU emulation were removed from Linux 7.2, as was a 40-year-old Hercules graphics card driver, AppleTalk [...]

Add multiple picture widgets to your Ubuntu desktop

If you remember that desktop picture widget for GNOME I wrote about last year, but found it a bit too basic for your personalisation preferences, you weren't alone. Another user felt it could lacked enough flexibility, so forked and improved it. Picture Desktop Widget Remake improves on the original. It lets add multiple picture widgets to your Ubuntu desktop, and assign each one a different folder to pull images from, at random. Plus, you can set the size, position, border radius and aspect ratio of each widget individually. Each photo frame has its own on/off button in Preferences, so you [...]
