Summary: Techrights is happy to report that its_presence_in_Geminispace (with

Gemini Protocol) pays off and later today we’ll hit another milestone

MAYBE it’s worth noting, as the month of April is now officially over, that in

the month of April we had record traffic in Gemini (about half a million

pages). Gemini started in 2019 and we joined 1.5 years later (it has more_than

quadrupled_since. It continues_to_grow. Ever since then we’ve_grown_our

capsules_to_46,000_pages (milestone due later today) and we’re_watching_closely

new pages in Geminispace (polling_every_hour_for_updates). Next year Gemini

turns 5. It has been a long and positive journey for us. █

Microsoft Misinformation Spew

Creative Commons Attribution-No Derivative Works 4.0

http://techrights.org/videos/spewing-anti-linux.webm

Summary: Today we publish two videos about Microsoft’s misinformation/

disinformation capabilities; by making an LLM ‘freely’ available, with built in

biases (controlled by Microsoft), anti-GNU/Linux lies and venomous statements

can proliferate without any attribution

THE past few days were spent catching up with news links and implementing new

curation tools (s/n ratio is awful in today’s Web). Daily Links have gone on

here for over 15 years (next month our IRC community turns 15 too) and they’re

very important for us.

“Sounds like Microsoft spreads misinformation using its so-called ‘news’ sites,

right? Do we want to use or rely on a chatbot from such a dishonest

company?”One reader asked for more details about the demise of Microsoft-

branded peripherals, but so far all press coverage we’ve found about it was

Microsoft puff pieces, misdirection, and face-saving, damage-limiting spin.

This is discussed in passing above. Certainly Microsoft isn’t doing well. The

“Microsoft Store” franchise died in 2020 and ever since then we’ve already

repeatedly heard of Azure layoffs (every year; the press suppressed this

information), which means that clown computing isn’t working out for Microsoft.

All that spare (unused) servers capacity is instead being wasted of “HEY HI”

(AI) gimmicks and vapourware. Trying to get people to actually use the darn

thing required a very expensive and relentless “marketing” campaign, borrowing

just about every trademark of Microsoft, conjoined with buzzwords (“Hey Hi!”)

and paid stenographers.

AWS is also having issues (and layoffs), but Amazon shares were up 10% at the

same time an MSN (yes, Microsoft) headline said “Amazon disappoints”… (double-

standards/hypocrisy all over this)

MSN itself had many layoffs, as did Bing (which is the main trademark Microsoft

uses to shill the chatbot).

Sounds like Microsoft spreads misinformation using its so-called ‘news’ sites,

right? Do we want to use or rely on a chatbot from such a dishonest company?

That too is discussed above.

“Not only is the company dishonest,” an associate noted, it “the chaffbot is

nearly always stubbornly wrong. “It would be very important to link to (and

describe briefly) how wrong it usually is,” this associate added. We’ll provide

some examples later.

“Information oligopolies and consolidation are hallmark of imperialism in the

digital realm.”Lest we forgot Google’s grip on the Web and Gulag Noise (Google

News) having a near monopoly. Phoronix, GamingOnLinux, and 9to5Linux (Michael,

Liam, and Marius; literally just 3 people) dominate the so-called “search”

results in Gulag Noise for terms like “Ubuntu” and “Linux”. Why aren’t more

GNU/Linux news sites included? Because they’re “advertiser-unfriendly” (i.e.

not sucking up to corporate power)? The source diversity in that Gulag

disservice is truly awful and they are not striving to fix that. Nor will

“Bard”…

Information oligopolies and consolidation are hallmark of imperialism in the

digital realm.

The video above speaks about Webspam or SPAM sites — a topic we’ve revisited

lately in light of a disturbing resurgence. Sites that are ‘written’ or

‘composed’ by SPAMBOTS (or generated by chaffbots/chatbots/automated

translation apparently) keep spreading lies and FUD about GNU/Linux… possibly

generated by Microsoft bots. They’re trained on GNU/Linux-hostile (and

censored) datasets, including sites sponsored by Microsoft, then curated in

Kenya by sweatshop-grade staff. It’s about institutionalising bias. Then, the

FUD comes out in bulk. No need for Microsoft to pay for shills, they need only

with some practical examples later today in another video. █

Microsoft Anonymising Its Propagandists

Creative Commons Attribution-No Derivative Works 4.0

http://techrights.org/videos/fud-machines-and-ars-technica.webm

Summary: Generating GNU/Linux-hostile chaff seems like a “side perk” of

Microsoft doing a month-long or months-long campaign for a rather worthless and

highly inaccurate chatbot (chaffbot), falsely marketing that chatbot as

conversational “HEY HI” (AI) or tool for composing E-mail, code, commits and so

THE video above deals with a certain resurgence of anti-”Linux” FUD. Some of

that seems to be computer- (or Microsoft-) generated, but not all of it, as we

noted_earlier_on. Microsoft basically creates weapons of misinformation.

We’ve long deemed this a potential topic, as this severe problem is only

growing and it’s not going away. We only needed to gather more material to

serve as evidence of the trend and this past week we found sufficient material.

At least some of that is computer-generated spew. That’s not a new problem, but

it can grow in intensity over time. “Because it is bot-generated,” an associate

noted, “that message will turn up elsewhere.”

“We’ve long deemed this a potential topic, as this severe problem is only

growing and it’s not going away.”“Speaking of [it],” the associate added, “I

notice (and you have seen before) that Ars [Technica] has relabled all of

[Peter] Bright’s articles as “Staff Writer” or somesuch” (for those who don’t

know, Bright is a serial child rapist who was promoted, then acted as editor

and moderator in that site for years).

So Reddit’s owner (Condé Nast) thinks that the issue right now is the name

(pedophile and child abuser), not the lies relayed by Microsoft through him.

What does this tell us about the media and about him?

“So Reddit’s owner (Condé Nast) thinks that the issue right now is the name

(pedophile and child abuser), not the lies relayed by Microsoft through him.

What does this tell us about the media and about him?”Citing this_piece_from

SecurityWeek (“RTM Locker Ransomware Variant Targeting ESXi Servers”), one

associate noted that this is “not a “linux” variant” and the topic should be

revisited in light of plenty such FUD lately (we found about a dozen this past

week alone and included those with quick rebuttals in Daily Links; the video

above shows_this_subset_of_the_lot; Gemini_equivalent_here).

“CISA panels are notoriously stacked (loaded with full-time Microsoft

staff).”Seeing the direction all this is going (media emitting disinformation),

and moreover noting that public_input_is_being_collected by the Microsoft-

infiltrated_CISA, the associate said that “FOSS participation needed” (Linux

Foundation is a_front_group_of_proprietary_software_vendors, so that won’t

count; OSI also fronts for Microsoft). “Industry vendors have until June 26 to

comment on the provisional document,” the report says, so we suppose they limit

themselves to input from corporations, not experts or ordinary members of the

public*. CISA panels are notoriously stacked (loaded with full-time Microsoft

staff). The_objective_is_‘privileged’_back_doors_rather_than_true_security. █

✐ The_Same_Mismanagement_and_Micromanagement_(Stalking/Bullying)_That_Caused

the_‘Suicide_Wave’_Under_Benoît_Battistelli⠀✐

Posted in Europe, Patents at 7:59 am by Dr. Roy Schestowitz

Last summer: EPO_Management_Severely_Harms_the_Health_of_Staff_by_Bullying_Them

This month: Corrupt_Administration_at_the_European_Patent_Office_is_Causing_a

Mental_Health_Crisis (published shortly before the letter below)

                 🄸🄼🄰🄶🄴_🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽_⦇Micromanagement⦈_

Summary: Micromanagement and microaggressions have become an habitual

occurrence and reality (“new normal”) at the EPO; managers try to push salaries

downwards and they_pressure_examiners_to_grant_patents_in_violation_of_the

rules

THE Local Staff Committee The Hague (LSCTH), or people who were recently

(re)elected by EPO staff (representation by consent, not by decree like António

Campinos), says there is growing concern for the mental health of EPO workers.

Benoît_Battistelli showed this can culminate in fatalities, but he, unlike

managers_at_France_Télécom, was never held accountable because the EPO operates

with complete impunity.

“Threatening tone from managers during a health crisis is worse than tasteless.

It can kill.”The letter below was disseminated among thousands of EPO workers

earlier this month. It does not name any manager in particular, but it does

speak of “constant reminders to increase the production pace, repeated

seemingly over-zealous quality checks, relentless micromanagement, part-time

request rejections, etc…”

There is also the “I’m paying you!” excuse for abusing people and ‘casually’

breaking the law (or EPC). There’s a mention of “colleagues in higher grades

who are apparently being told that they are “being paid too much”, colleagues

who are more fragile due to health conditions or having young children,

colleagues on 5-year contracts, etc…”

Here is the full message:

 § Work pressure and micromanagement – Are you suffering at work?

 Contact health practitioner and staff representation⠀➾

 Dear colleagues,

 Due to under recruitment the pressure to produce has been increasing

 over the years.

 We have been made aware of colleagues – whose work was previously

 often recognized, appreciated and rewarded – now being put more and

 more under intense scrutiny by their line management. This can take

 many forms, e.g. constant reminders to increase the production pace,

 repeated seemingly over-zealous quality checks, relentless

 micromanagement, part-time request rejections, etc…

 Although this situation is affecting most colleagues, we note a

 pattern that certain groups seem to be particularly targeted:

 colleagues in higher grades who are apparently being told that they

 are “being paid too much”, colleagues who are more fragile due to

 health conditions or having young children, colleagues on 5 -year

 contracts, etc…

 We would like to remind all colleagues that:

 - if your work is affecting your health – trouble sleeping,

 headaches, exhaustion…- you should contact your general practitioner

 and OHS and consider taking sick leave; and

 - if you feel that you are being targeted by your line management,

 you are not the only one and you should contact your staff

 representation as soon as possible.

 Kind regards,

 Local Staff Committee The Hague (LSCTH)

Remember that life isn’t about work. Some people work to live, but they should

not mistake that for workplace as a home/family. If you cannot take the abuse

anymore, consider leaking out evidence of the bullying, as some people did

throughout the pandemic. Threatening tone from managers during a health crisis

is worse than tasteless. It can kill. █

Summary: The Putin-_and_Belarus-linked EPO (Benoît_Battistelli and António

Campinos sent plenty of money and data to Minsk) is wondering how to compel

workers_to_do_illegal_things and always contemplating ways to fake “production”

(even if this Russian roulette of an office drives 7 people to suicide in just

a few years; they’ve learned nothing from that [1, 2, 3])

Tackling Sirius_Fraud at the Police

Creative Commons Attribution-No Derivative Works 4.0

http://techrights.org/videos/sirius-and-the-police.webm

Summary: The managers at Sirius_‘Open_Source’, who don’t even use GNU/Linux and

who steer away from Open Source, stole_a_lot_of_money_from_many_GNU/Linux

engineers and were reported to the police; but it’s rather revealing and

telling that the police does not prioritise prosecution against white-collar

criminals (cops would rather deal with poor shoplifters and such)

“Action Fraud is the UK’s national reporting centre for fraud and cyber crime

where you should report fraud if you have been scammed [or] defrauded,” says

the site at actionfraud.police.uk, which Greater_Manchester_Police_asked_me_to

go_to. So 8 days ago I did and my expectation was that they would be slow to

progress. As noted in the video above, it’s not just about myself as other

former colleagues are victims of the same crime and they too are chasing this.

“As noted in the video above, it’s not just about myself as other former

colleagues are victims of the same crime and they too are chasing this.”This

video may seem unrelated to tech, but one must consider what Sirius ‘Open

Source’ is and what it claims to be. This is turning out to be a massive

embarrassment in the UK because clients of Sirius ‘Open Source’ (scare quotes

intentional) were some of the very largest public institutions in the UK and

elsewhere. What if they realised that a firm that calls itself “Open Source” is

managed by people who reject Open Source and who engage in fraud against

engineers who do in fact insist on Open Source? What would these large public

institutions in the UK think? █

            # ⚓ Barry Kauler ☛ Preliminary_support_for_fscrypt_v2⠀⇛

                   The ext4 filesystem supports per-folder encryption,

                   called

                   “fscrypt”. This is a feature that can be enabled

                   using the ‘tune2fs’

                   utility.

                   In EasyOS, the working-partition (usually) has

                   fscrypt enabled, and

                   some folders are encrypted. This means, if the

                   drive is stolen, no one

                   will be able to read the contents of those folders.

                   The advantage of encrypting a folder, compared with

                   a file as may be

                   done in Puppy Linux, is the folder has no size

                   limit, or rather, it is

                   the limit of free space in the partition.

                   There is a utility name ‘e4crypt’ in the initrd,

                   that decrypts these

                   folders at bootup. Easy has used this utility up

                   until the present;

                   however, it is what is called “version 1″ fscrypt,

                   and has some serious

                   problems with multiple users.

                   When I took Easy down the path of running apps as

                   separate users,

                   things got complicated. I had to use the ‘keyctl’

                   utility for each user

                   to decipher the folders. And recently it got even

                   more complicated with

                   Flatpaks, that run in a sandbox and have great

                   difficulties with

                   recognizing the kernel keys — meaning unable to

                   access the encrypted

                   folders.

                   Since the 5.4 kernel, I think about 2020, there has

                   been fscrypt v2,

                   that looks like it might make usage with multiple

                   users much easier.

                   Here is some early information about v2:

                   based interactive

                   frontend, language-server-protocol backend

                     git tag release-4.9 (commit ebb424eee5599fc)

                     There have been over 70 commits since the last

                   release.

                     There have been 10 bugs fixed / features added

                   since the last release.

                   = SystemTap backend changes

                   * Corrected handling of DWARF5 implicit-pointer and

                   entry-value data

                     and bit-fields.

                   * Corrected accidental runtime double-hit of some

                   types of synthetic

                     probes.

                   * Improved kernel backtrace repeated artifacts.

                   = SystemTap frontend (stap) changes

                   * Added a Jupyter based front-end to stap.  This

                   may be invoked via a

                     container - or built locally (likely via pip3

                   downloads).  The user

                     interface becomes an interactive notebook in a

                   Anyone who has setup a website will appreciate that

                   SSL/TLS requires a web server to have an SSL

                   certificate authenticating its identity. However,

                   while TLS requires a server certificate, it also

                   has optional support for client certificates,

                   whereby a client connecting to a TLS server must

                   also authenticate its identity to the server. Just

                   as in the case of server certificates, this is done

                   by presenting a certificate and proving ownership

                   of the corresponding private key.

                   it helps to understand that this approach may be

                   harmful to human relationships (which could explain

                   the social awkwardness of hackers), but it remains

                   useful as a method to improve the design of

                   safety of computer systems. When a system fails

                   it runs, which cron will email to the crontab’s

                   owner (or MAILTO setting). This means that this

                   machine is now running right at the edge of its

                   sending ratelimit; if it generates even one more

                   email message (for example from some other cron job

                   that runs once a day to notify you about pending

                   never recover and will always have something in its

                   local mail queue. If it sends a second extra email,

                   where you want to play the game! I run Sunshine on

        Bug_Fixes⠀⇛

             Debian 11.7 is here almost four and a half months after

             Debian 11.6 to provide those who want to deploy the

             Debian GNU/Linux 11 “Bullseye” operating system series on

             new computers with up-to-date installation media so you

             won’t have to download hundreds of updated from the

             repositories after the installation.

             This means that Debian 11.7 includes all the security and

             software updates that have been released from December

             17th, 2022, when Debian GNU/Linux 11.6 was released,

             until today. In numbers, Debian 11.7 includes a total of

             102 security updates and miscellaneous bug fixes for 92

             packages.

* ⚓ Debian ☛ Debian_Installer_Bookworm_RC_2_release⠀⇛

       The Debian Installer team[1] is pleased to announce the second

       release

       candidate of the installer for Debian 12 "Bookworm".

       Improvements in this release

       ============================

        * apt-setup:

           - Enable <codename>-updates when installing testing, not

       only

             when installing (old)stable (#991947).

        * argon2:

           - Restore threading support in the installer (#1034696).

        * base-installer:

           - Install zstd alongside initramfs-tools, like busybox.

        * choose-mirror:

           - Update Mirrors.masterlist.

        * cryptsetup:

           - Improve support for low-memory systems (#1028250): Check

for

             physical memory available also in PBKDF benchmark, and

       use only

             half of detected free memory on systems without swap.

        * debian-cd:

           - Include zstd alongside initramfs-tools, like busybox.

        * debian-installer:

           - Fix grub font loading, making sure we get the nice

       graphical

             splash screen in Secure Boot mode too (#1034535).

        * grub-installer:

           - Install shim-signed on i386 and arm64 as well as amd64

       when

             we're installing grub-efi-*-signed packages.

           - If we detect other operating systems installed, check

       with the

             user (at low priority) and re-enable os-prober.

        * grub2:

           - Add debconf logic for GRUB_DISABLE_OS_PROBER to make it

       easier

             to control things here, particularly useful for the

       installer

             (#1031594, #1012865, #1025698).

           - Add luks2 to the signed grub efi images (#1001248).

           - Fix probing of LUKS2 devices (#1028301).

           - Fix Secure Boot on arm64 (#1033657).

           - Don't warn about os-prober if it's not installed

       (#1020769).

           - Fix an issue where a logical volume rename would lead

       grub to

             fail to boot (#987008).

        * live-installer:

           - Remove the live packages before the cdrom is unmounted,

             avoiding a long wait at the end of the installation

       process.

        * partman-efi:

           - Fix detection of BIOS-bootable systems, fixing at least

the

             "Guided - use entire disk and set up LVM" use case on

       UEFI

             systems (#834373, #1033913).

        * preseed:

           - Restore support for the "hostname" alias on the kernel

       command

             line (#1031643, #1034062).

           - Switch auto-install/defaultroot to bookworm.

       Hardware support changes

       ========================

        * flash-kernel:

           - Adjust OLPC XO-1.75 boot script.

           - Add Lenovo Miix 630 and Lenovo Yoga C630.

           - Add StarFive VisionFive board.

           - Add Lenovo ThinkPad X13s.

           - Add Colibri iMX6ULL eMMC.

           - Add Raspberry Pi 3 Model B Plus Rev 1.3.

        * linux:

           - udeb: add intel_lpss* (optional) to kernel-image

       (#1032136).

             Many laptops have their touchpad accessible over I2C,

       only

             visible if LPSS is available in the installer.

       Localization status

       ===================

        * 78 languages are supported in this release.

§ Canonical/Ubuntu Family⠀➾

* ⚓ Neowin ☛ Ubuntu_23.10_goes_all-in_on_the_mythical_creature_theme_with

  Mantic_Minotaur_codename⠀⇛

       Canonical has announced that Ubuntu 23.10, which is due out in

       October, will carry the codename Mantic Minotaur. It’s typical

       for Ubuntu to receive a codename of an endangered animal like a

       Pangolin but it seems with this release, the company has

       decided to go entirely with non-existent creatures.

       The adjective, Mantic, “relating to divination or prophecy”,

       comes from the Greek word mantikos and mantis which means

       prophet. So you could read Mantic Minotaur as Prophetic

       Minotaur.

       The disclosure of the codename for Ubuntu 23.10 comes nearly a

       month after the cycle’s calendar was published in which it

       states that a beta will be made available on 21st September and

       the final release due on 12th October. The beta will give the

       public an opportunity to try it out and report any last-minute

       bugs that developers may have missed.

§ Devices/Embedded⠀➾

* ⚓ Linux Gizmos ☛ TESPuino_board_comes_in_an_Arduino_UNO_form-factor⠀⇛

       Kickstarter featured this week an Open-source development

       ESP32-based board designed for learning and quick prototyping.

       The TESPuino provides up to 14x GPIOs, 1x MicroSD card slot for

       storage and 1x USB Type-C port programming and power.

§ Open Hardware/Modding⠀➾

* ⚓ Hackaday ☛ Building_A_WiFi_Picture_Frame_With_An_EInk_Display⠀⇛

       LCD photo frames never really caught on — by emitting light,

       they didn’t seamlessly blend in with a home’s decor in the way

       printed photos do. [Sprite_tm] decided to see if a color e-Ink

       screen could do any better, and whipped up a WiFi-enabled photo

       frame using a Waveshare display.

* ⚓ Adafruit ☛ Raspberry_Pi_tripod_and_Camera_Support⠀⇛

       Shared by feiticeir0 on Thingiverse, this neat tripod and

       camera support comes in handy!

* ⚓ Andrew Hutchings ☛ Schneider_Euro_PC:_Restoration_Part_3⠀⇛

       Last time I got as far as the Euro PC showing tons of BIOS

       errors on the screen, which is a good first step. This time I

       try to get a little further…

* ⚓ Tom’s Hardware ☛ New_App_Shows_Raspberry_Pi_Pico_Pinout_at_Command

  Line⠀⇛

       Pinout.xyz has released a new command line-based GPIO pinout

       chart for the Raspberry Pi Pico microcontroller.

* ⚓ Hackaday ☛ The_World’s_First_Agricultural_Right_To_Repair_Law⠀⇛

       Long time readers will know that occasionally we mix up our

       usual subject matter with a dash of farm equipment. Usually the

       yellow and green variants that come from John Deere, as the

       agricultural manufacturer has become the poster child for all

       that is wrong in the fight for the right to repair. An old

       Deere is worth more than a nearly new one in many places,

       because for several years now their models have had all their

       parts locked down by DRM technologies such that only their own

       fitters can replace them. Now after a long legal fight

       involving many parties, the repair and parts company iFixit

       sound justifiably pleased as they announce the world’s first

       agricultural right to repair law being passed in the US state

       of Colorado. (Nitter)

      o ⚓ It’s FOSS ☛ “Meet_the_Techs_of_Tomorrow_Where_They_Are_Today”:_A

        Conversation_With_Stu_Keroff⠀⇛

             I remember reading an article about Linux back in (maybe)

             1998 or 1999, and I was fascinated by it, but I didn’t

             actually try it for the first time until late 2005.

             I obtained a used computer from a tech friend and started

             experimenting with it. My first distros were Linspire and

             Mepis. From there, I moved to Ubuntu. At first, it was

             just having fun and learning how to make things work.

             Then, I started trying to do more of my teaching work

             using Linux. Then, it was getting students interested and

             involved.

             I first started doing Linux clubs at school back in 2012,

             and the whole thing started by accident. Our school had

             started a 1:1 laptop program that year, and almost

             immediately students started breaking and losing laptops.

             I wanted to integrate tech into my teaching, but I would

             have students in each class that did not have a laptop

             because they had broken it.

      o § Events⠀➾

            # ⚓ Volker Krause ☛ Linux_App_Summit_2023⠀⇛

                   Last weekend I attended the Linux_App_Summit_(LAS)

                   2023 in Brno, Czechia,

                   to speak_about_push_notifications and to get a few

                   remaining_interoperability_issues sorted out.

                   § LAS

                   While my goal for last_LAS was to finally

                   meet people in person again for the first time

                   since the pandemic, I had a much more specific

                   objective this time,

                   get the remaining questions around UnifiedPush on

                   Linux sorted out.

            # ⚓ Abhijith_PA:_Attending_FOSSASIA_2023⠀⇛

                   I attended FOSSASIA_2023 summit held

                   at Lifelong Learning Institute,

                   Singapore. A 3 day long parallel talk filled

                   conference. Its my second

                   time attending FOSSASIA. The first one was 2018

                   summit. Like

                   last time, I didn’t attend much talks but focussed

                   on networking with

                   people. A lot of familiar faces there. PV Anthony,

                   Harish, etc.

                   I vounteered to run Debian Booth at the exhibition

                   hall distributing

                   stickers, flyers. Rajudev also helped me at the

                   booth. Most of the

                   people there used debian or its derivates or know

                   debian already, its

                   easier for me that way, that I don’t have do much

                   explaining compared

                   to other booths. Thanks to Parth for looking after

                   Dear all,

                   I am happy to announce the 20th stable version of

                   Gnuastro: version 0.20.

                   Gnuastro is an official GNU package, consisting of

                   various command-line programs, C/C++ library

                   functions and Makefile extensions for the

                   manipulation and analysis of (astronomical) data.

                   All the programs share the same basic command-line

                   user interface (modeled on GNU Coreutils). For the

                   full list of Gnuastro’s library, programs, and

                         PyTest is a popular testing framework for

                         Python programming language. Fixtures in

                         PyTest provide a way to manage the resources

                         and data required for running tests. They

                         simplify the process of setting up, tearing

                         down, and sharing test data between test

                         functions. PyTest fixtures provide a

                         convenient way to define these resources and

                         data once and reuse them across multiple

                         tests, saving time and reducing the chance of

                         errors.

                         In this tutorial, you will learn what PyTest

                         fixtures are, why they are used, and how to

                         define and use them in your tests. To explore

                         the usage of Pytest fixtures, you’ll be

                         creating a simple note-taking application

                         that lets users add, edit, and get notes.

                         Gtk4 has interesting ways of splitting models

                         and views. One that I didn’t find

                         very well documented, especially for Python

                         bindings, is a set of radio buttons

                         backed by a common model.

                         The idea is to define an action that takes a

                         string as a state. Each radio

                         button is assigned a string matching one of

                         the possible states, and when the

                         state of the backend action is changed, the

                         radio buttons are automatically

                         updated.

                         All the examples below use a string for a

                         value type, but anything can be used

                         that fits into a GLib.Variant.

             it was just what the doctor ordered.

             Japan are a great way to explore with a headache. Maybe

             One of my favourite parts of travelling to a destination

             take a break from thinking about all of the details of my

             journey. With that said, there are many airports without

             pianos, and many more that have one piano in a single

             terminal but no pianos in other terminals. I was speaking

             with a few people about how we could help place pianos in

             airports where one is not available, providing travellers

             with the ability to have the same experience I and many

             other travellers have: a moment to sit back and make

             music between legs of a journey.

                   successes – both the Mars rovers and the current

                   copter came from such experimental beginnings. I

                   argued that letting some spirit of experimentation

                   In 2017, as lawyers for prisoners in Ohio sought to

                   spare their clients from lethal injection, they

                   challenged one of the state’s key witnesses: Daniel

                   Buffington.

                   As he had done elsewhere, the Florida-based

                   pharmacist had submitted written testimony saying

                   that prisoners would not feel pain from the three-

                   drug cocktail administered by executioners. But the

                   lawyers for the men on death row argued that

                   Buffington was unqualified to testify in an

                   upcoming hearing, noting that he had not

                   administered general anesthesia or conducted

                   research on midazolam, the key sedative in the

                   Last winter, Dr. Gail Van Norman sat on the witness

                   stand in the federal courthouse in Oklahoma City,

                   testifying as part of a trial that would determine

                   whether Oklahoma’s lethal injection procedure was

                   constitutional. Two weeks earlier, at the request

                   of lawyers representing more than two dozen

                   prisoners, Van Norman, an anesthesiologist and

                   professor at the University of Washington, had

                   attended the execution of a man named Gilbert Ray

                   Postelle.

                   In the execution chamber, she testified, Postelle

                   was lying face-up on a gurney with his arms

                   stretched out beside him. Executioners injected him

                   with midazolam, a drug that was supposed to knock

                   him unconscious so he didn’t feel pain from two

                   drugs that would soon paralyze him and stop his

                   heart. It didn’t appear to work. For 2 1/2 minutes

                   after receiving midazolam, Postelle continued to

                   wiggle his hands and feet. His eyes remained open,

                   blinking and looking up at the ceiling. Postelle’s

                   breathing became increasingly strenuous and rapid.

                   Van Norman said his trouble breathing was a result

                   of the large dose of midazolam.

                   also need a balun to reduce noise or unwanted

                   bootup is used to create the encrypted folders.

                   Master keys must be real cryptographic keys, i.e.

                   indistinguishable from random bytestrings of the

                   same length. This

                   On April 18, 2023, the European Commission

                   published its proposal for an EU Cyber Solidarity

                   Act (“CSA”). It aims to strengthen incident

                   detection, situational awareness, and response

                   capabilities, and to ensure that entities providing

                   services critical for day-to-day life can access

                   expert support to manage their cyber risk and

                   respond to incidents. Specifically, the CSA aims to

                   promote information sharing about cyber incidents

                   and vulnerabilities, to help improve the cyber

                   resilience of critical entities, and to create an

                   EU-wide resource for incident management.

                   The CSA adds another layer to the increasingly

                   crowded landscape of EU cybersecurity laws. The

                   proposed law would interact with the revised

                   Network and Information Security Directive (“NIS2”)

                   and certifications issued under the Cybersecurity

                   Act. Private companies in specific sectors will

                   also have to consider potential overlap with the

                   forthcoming Cyber Resilience Act and the financial

                   services-focused Digital Operation Resilience Act.

                   most likely interpretation will be incorrect”

                   insofar as this is possible in lojban. Here a line

                   break is used to trick the reader; we start off

                   with “a green tree” but the next line gives a bo

                   which joins the tree tighter to pipybanfi, so it’s

                   a (green (tree frog)) once you get to the second

                   line, not the default ((green tree) frog) without

                   the bo. Garden path sentences are really better

                   done in not lojban, where you can usually play

                   around with homonyms, verb nouns, or who knows what

                   else to really cause the reader to stop and have to

                         Too much of what we do in our industries is

                         improving on products that have long passed a

                  # ⚓ Unveiling_`guprecords.raku`:_Global_Uptime_Records

                    with_Raku⠀⇛

                         For fun, I am tracking the uptime of various

                         personal machines (servers, laptops,

                         workstations…). I have been doing this for

                         over ten years now, so I have a lot of

                         statistics collected.

                         As a result of this, I am introducing

                         `guprecords.raku`, a handy Raku script that

                         helps me combine uptime statistics from

                         multiple servers into one comprehensive

                         report. In this blog post, I’ll explore what

                         Guprecords is and some examples of its

                         application. I will also add some notes on

                         Raku.

                         Ending up at a big tech company and spending

                         many years in Java land, I gravitated towards

                         modern graphical IDEs. At the time Eclipse

                         was dominant; it was also, for the size of

                         codebases we were using and the speed of

                         computers at the time, incredibly slow. I

                         logged hundreds of milliseconds to respond to

                         a keypress.

                         You can quickly identify the nature of a link

                         with a few lines of CSS. According to the

                         protocol (http, gopher, mailto…), or if the

                         link is an inner link, a tiny icon will be

                         displayed next to it…

                    of)⠀⇛

                         A while back the Rust project switched from

                         recommending the Rust Language Server (rls)

                         to officially supporting it’s replacement,

                         rust-analyzer for use in IDE’s and editors.

                         There were solid technical reasons for the

                         change, but the rollout was not without some

                         growing pains.

                         One issue with using an lsp server in the

                         context of Rust is that it is common for

                         people to have multiple versions of the Rust

                         toolchain on their system. Most people who

                         use Rust in anger have at least a stable

                         toolchain and a nightly, while some projects

                         (such as the Linux kernel) requiring a

                         specific stable compiler version. It’s not a

                         problem due to the language changing that

                         fast (although a few years ago it would have

                         been). The issue is that in order to support

                         procedural macros rust-analyzer must be built

                         from the same source as the compiler in use.

                         That means that one would need a version of

                         the program for each toolchain, and a way to

                         switch between them.
