Calamares is a distro- and desktop-agnostic Linux installer. It’s my day job. It is named for squid, in particular battered squid rings from the Mediterranean sea, Calamares. There’s lots of ways to catch squid and octopuses. One way is to use an octopus trap, and in Japan these have a fairly distinctive shape and are called tako tsubo. There is a specific kind of heart spasm that causes the left ventricle to take on the shape of an octopus trap; this is generally Not Good. Here’s a cute illustration from a squid-lover.

This focuses on gender and nationality, not anything technical or corporate ("The Committee is comprised of 4 women, 3 men, and 0 nonbinary individuals"). Creating quotas for "nonbinary individuals" means there's a career incentive to change gender; that can propel people into positions of power just to meet diversity quotas. Criteria that would be more meaningful would be, works or does not work for large monopolist because it is well known what harms Free software communities the most, based on history.

Kodi 19.2 Improves Xbox Support and Support for Devices Running Old Android Versions

Filed under

Software

Kodi 19.2 is here five months after Kodi 19.1, which introduced initial support of the Kodi 19 “Matrix” series for the Xbox gaming console, added better support for SMB shares, improved reliability for HTTP and NFS network filesystems, enabled file caching by default for network filesystems, and fixed playback of optical DVDs in Linux.

The big news in Kodi 19.2 is that Xbox support has been greatly improved. For example, it improves the performance of the HEVC DXVA2 decoder using 128 byte aligned decoder surfaces, improves support for 10-bit swap chain surfaces used for HDR-capable TVs, and improves swap chain performance when using the DXGI_SWAP_EFFECT_FLIP_DISCARD variable.

  • Speak to me! – Purism

    My trusty laptop’s speakers gave up the ghost. I don’t like to sit around in headphones all the time, I don’t have any other speakers, and the replacements are still being manhandled by the postman. I’d get used to the austerity if I hadn’t started missing calls from a friend. That’s unacceptable! But what am I supposed to do? Buy extra gadgets just to throw them away after a week? Nope, I’m not that kind of a person. But hey – I have a Librem 5! It has a speaker. It’s open. I have control over it, and I’m a hacker too. So I should be able to come up with a hack to turn it into a speaker for my laptop, right? Pulseaudio to the rescue. I look through the guide. There it is: forwarding audio over a network.

    Recently, some colleagues commented about validating if users in a Telegram group were or not employees anymore, so that the process could be automated without having to chase down the users that left the company. One of the fields that can be configured by each user, is the link to other platforms (Github, LinkedIn, Twitter, Telegram, etc), so querying an LDAP server could suffice to get the list of users. First, we need to get some data required, in our case, we do anonymous binding to our LDAP server and the field to search for containing the ‘other platform’ links.
