KDE Plasma 6 Is Now 'Fairly Livable'
by Peter Reutemann 20 Jun '23

20 Jun '23

'Prominent KDE developer Nate Graham believes that Plasma 6 is now "fairly livable" and recommends KDE developers and power users / enthusiasts start giving it a try. Phoronix reports: He characterized Plasma 6 as: "Basically everything in Plasma compiles with Qt 6, and at this point Plasma 6 is fairly livable. To give you a sense of how livable, it's good enough that over the past 2 months, I've gone on three KDE-related trips from the USA to Europe, with my only computer running Plasma 6 in "current git master" state, with work-in-progress merge requests applied! Its stability has been good enough that this has caused me no apprehension, and indeed, it's been totally fine on each trip. So seriously, if you're a KDE developer or an adventurous user, start living on Plasma 6! Jump right in, the water's fine. :)" He went on to write more about the current development activities around Plasma 6. He also shared his personal beliefs around Plasma 6.0 release timing although no official release schedule is yet to be determined. Nate's belief is that Plasma 6.0 will likely be ready for release sometime between December and March.' -- source: https://developers.slashdot.org/story/23/06/19/212256 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

The State Of Linux Music Production
by Lawrence D'Oliveiro 17 Jun '23

17 Jun '23

Been messing about with my old MIDI keyboard again, after a long while putting it aside. It now complains about a “low battery” warning, but I think that only affects the onboard sound settings, which I’m not particularly fussed about. I got a USB-MIDI interface a few years back, and I can use that with the keyboard to drive sound sources on my main machine. But things have changed in the Linux music world since the last time I tried this (at least on Debian). JACK and PulseAudio have both been replaced by this new thing, PipeWire, which is supposed to handle video, audio and MIDI routing through a common architecture. So I no longer have to start up jackd when I want to switch to music-production mode (in fact, trying to run jackd under PipeWire will screw up your audio something awful). Instead, patching between sources and sinks is done via WirePlumber, for which a convenient GUI frontend is available in the form of qpwgraph. All the main PipeWire-related processes are managed as user-level services via systemd. One thing hasn’t changed, and that is the incompatibility between ALSA MIDI ports and JACK MIDI ports: that USB-MIDI interface only appears to the system as ports of the ALSA kind, whereas JACK-aware apps want to accept MIDI data via ports of the JACK kind. So I still have to start up the old “a2jmidid” program to provide a bridge between these two. qpwgraph shows all these different kinds of entities, each labelled with its type: “ALSA”, “PW” (PipeWire) or “JACK”. The latter two can be connected directly to one another, while ALSA ports can only be connected to ALSA ports. The colour-coding--purple for ALSA MIDI ports, red for JACK/PipeWire MIDI, green for JACK/PipeWire audio--is a hint that you can only connect matching colours. Some JACK-aware apps still have trouble running under PipeWire; for these, there is the “pw-jack” tool, which substitutes the JACK dynamic libraries with ones that hook directly into PipeWire before launching the specified app. E.g. I had to run a2jmidid with pw-jack a2jmidid Also, the command pw-jack zynaddsubfx -O jack tells ZynAddSubFX to run with its JACK interface active, and I can route events from my keyboard to it via the intermediary nodes automatically created by a2jmidid. Don’t forget to hook up its audio output terminals to the box representing my speakers, and voilà, I can make sound.

Analysis Of The GMail Fake Email Exploit
by Lawrence D'Oliveiro 15 Jun '23

15 Jun '23

You may have heard about an interesting hack a few days ago <https://www.theregister.com/2023/06/09/google_bimi_email_authentication/>, where some low-lifes figured out how to send fraudulent emails to GMail users that showed a “verified” blue BIMI checkmark, indicating that the recipient could trust the from-address as authentic. But of course it was not. The details of how the hack was perpetrated are quite intricate, and involve some subtle interplay between the mail-processing policies of GMail (where the recipients had their accounts, and which implements the BIMI check), Microsoft (which ran the Exchange servers where the fraudsters got accounts, and from which the fraudulent messages were sent) and UPS (the purported sender of the fake emails). Of course, all three parties have since taken action to ensure this particular scenario will not happen again. ThioJoe offers up a good explanation of how it all worked here <https://www.youtube.com/watch?v=Czc0F_A82rE>. If your eyes glaze over at the mention of SPF versus DKIM versus DMARC--well, you’re not alone. When I looked at whether I should implement something like this on my own mail server to try to ensure that spammers could not send out fake emails under my name, I felt the same way. So I just decided not to bother. For now ...

Edge Sends Images You View Online To Microsoft
by Peter Reutemann 13 Jun '23

13 Jun '23

'Not so long ago, Microsoft Edge ended up in hot waters after users discovered a bug leaking your browser history to Bing. Now you may want to toggle off another feature to ensure Edge is not sending every picture you view online to Microsoft. Edge has a built-in image enhancement tool that, according to Microsoft, can use "super-resolution to improve clarity, sharpness, lighting, and contrast in images on the web." Although the feature sounds exciting, recent Microsoft Edge Canary updates have provided more information on how image enhancement works. The browser now warns that it sends image links to Microsoft instead of performing on-device enhancements.' -- source: https://yro.slashdot.org/story/23/06/12/182216 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

12 Jun '23

'Slashdot reader e065c8515d206cb0e190 shared the big announcement from Debian.org: After 1 year, 9 months, and 28 days of development, the Debian project is proud to present its new stable version 12 (code name bookworm). bookworm will be supported for the next 5 years thanks to the combined work of the Debian Security team and the Debian Long Term Support team... This release contains over 11,089 new packages for a total count of 64,419 packages, while over 6,296 packages have been removed as obsolete. 43,254 packages were updated in this release. The overall disk usage for bookworm is 365,016,420 kB (365 GB), and is made up of 1,341,564,204 lines of code. bookworm has more translated man pages than ever thanks to our translators who have made man-pages available in multiple languages such as: Czech, Danish, Greek, Finnish, Indonesian, Macedonian, Norwegian (Bokmål), Russian, Serbian, Swedish, Ukrainian, and Vietnamese. All of the systemd man pages are now completely available in German. The Debian Med Blend introduces a new package: shiny-server which simplifies scientific web applications using R. We have kept to our efforts of providing Continuous Integration support for Debian Med team packages. Install the metapackages at version 3.8.x for Debian bookworm. The Debian Astro Blend continues to provide a one-stop solution for professional astronomers, enthusiasts, and hobbyists with updates to almost all versions of the software packages in the blend. astap and planetary-system-stacker help with image stacking and astrometry resolution. openvlbi, the open source correlator, is now included. Support for Secure Boot on ARM64 has been reintroduced: users of UEFI-capable ARM64 hardware can boot with Secure Boot mode enabled to take full advantage of the security feature. 9to5Linux has screenshots, and highlights some new features: Debian 12 also brings read/write support for APFS (Apple File System) with the apfsprogs and apfs-dkms utilities, a new tool called ntfs2btrfs that lets you convert NTFS drives to Btrfs, a new malloc implementation called mimalloc, a new kernel SMB server called ksmbd-tools, and support for the merged-usr root file system layout... This release also includes completely new artwork called Emerald, designed (once again) by Juliette Taka. New fonts are also present in this major Debian release, along with a new fnt command-line tool for accessing 1,500 DFSG-compliant fonts.

Microsoft Excel Has Become A Threat To Democracy
by Lawrence D'Oliveiro 07 Jun '23

07 Jun '23

Austria’s Social Democratic Party recently held an election for a new leader, according to <https://www.theregister.com/2023/06/06/austria_election_excel_blunder/>. Trouble was, two days after announcing the result had gone one way, they then had to report that in fact it was the other way round, owing to a stuffup involving an Excel spreadsheet. I suppose the only good news is that this was strictly an in-party election, not something involving any level of Government.

The State Of Fibre Broadband In The USA
by Lawrence D'Oliveiro 07 Jun '23

07 Jun '23

Came across this report <https://arstechnica.com/tech-policy/2023/06/internet-users-love-fiber-servi…>, which is interesting to compare with conditions in NZ: In terms of availability, the Federal Communications Commission broadband map indicates that about 38 percent of US residents can get fiber. The percentage drops to 29 percent when including only fiber services that offer gigabit download speeds and at least 100Mbps upload speeds. Basically, US broadband is dominated by companies with heavy investments in cable (and some ADSL), who have no interest in obsoleting that investment any sooner than they have to. Moral: there are places where a free market works, but strategic infrastructure buildouts is not one of them.

Trouble Accessing .nz Sites, Anybody?
by Lawrence D'Oliveiro 30 May '23

30 May '23

Seems some people have had trouble accessing various .nz sites since last night, and into this morning <https://www.nzherald.co.nz/business/banking-apps-some-websites-down-as-inte…>. The explanation at the end seems to indicate that InternetNZ is rolling out DNS security, and caching inconsistencies on ISPs’ servers are leading to hiccups for users. Hopefully this will be resolved soon as the outdated DNS entries get flushed.

Microsoft Releases Azure Linux
by Lawrence D'Oliveiro 26 May '23

26 May '23

Microsoft has announced a commercially-supported product it calls “Azure Linux” <https://devclass.com/2023/05/25/azure-linux-released-at-build-where-microso…>. This is essentially the same code as its custom “CBL-Mariner” distro that it runs internally on its Azure servers. While this is RPM-based (the same package manager used in Red Hat), it is not a fork of Red Hat, but is built specially from the ground up. Project lead Jim Perrin explains why: “The reason we chose not to fork a different distro … Microsoft has kind of a history with Linux. … I think the Balmer quote is from 2001, but a lot of the sentiment still lingers even today. Part of the reason we did not choose to start with a distribution and then fork it for our needs is we didn’t want to be seen as doing the embrace and extend thing again, we didn’t want to wake any of that up, we figured, build it from scratch, we can tailor it to our needs … we’re scratching an itch we had and offering the solution back to the community.” The “Ballmer quote” being the infamous phrase “Linux is a cancer” that then-CEO Steve Ballmer uttered back in 2001. Yes, nice to see some past sins are still kept in mind, at least in some corners of Microsoft ...
