Lessening Free Speech Is Not Ethics
Creative Commons Attribution-No Derivative Works 4.0

🄸🄼🄰🄶🄴 🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽 ⦇I'm trying to blacklist; I mean, killfile; I mean, denylist⦈
Summary: In the name of “protecting us” the folks_at_Microsoft_Canonical herald
a new era of censorship and self-censorship
THE INTERNET is becoming more oppressive a space over time. I’m not so old —
nor a “traditionalist” — but I think the way things are going is truly
Orwellian. It’s further magnified by centralised platforms such as social
control media and corporations that control Free software communities — to the
point of policing speech. Of course they call that “Open Source” and speak of
“conduct” (code word for control by those corporations).
Enter_Canonical. Yesterday it published “Inclusive Language and its Future at
Canonical” — a post that I wanted to respond to in video form. It’s harder to
take videos out of context.
“Are we mandating tolerance of corruption?”This issue isn’t a cross-
generational thing. It’s not even about age. It’s about corporate interests and
a divide-and-rule strategy, akin_to_trolling by the most_hypocritical_companies
out_there. A few months ago I turned 40 and my site has just turned_20 (I’m
hardly new to the Web; I’ve made sites since I was 15 and I’ve used IRC since I
was about 13; it was prior to that when I had practised some simple
programming). The actual technical progress made since then is nearly zero.
We’ve had technology turned against its users, using misleading doublespeak
like “smart” and “clown computing”. At the same time there was a watering down
of language — to the point where condemning a_criminal_company_like_Microsoft
is_considered_"hateful". You know we’ve gone too far when criminals are
protected from “offence”. Are we mandating tolerance of corruption? █
Note/clarification regarding meme: When you ban someone or ban whole groups
(e.g. IP addresses from China) there’s no “polite” term/way to put it. It’s a
never-ending or circular game of word-shuffle. It’ll appease nobody but
xenophobic corporations which abhor speech (except their own), and that
appeasement will only be temporary anyway. It’s a pretext or excuse for ‘agenda
creep’, governed_by_corporations,_not_communities.

# ⚓ OS News ☛ The_first_Asahi_Linux_Alpha_Release_is_here⠀⇛
This is an absolutely stunning effort and
achievement by the Asahi team, but as a mere user,
this whole thing does not exactly instill me with
the confidence needed to buy Apple hardware to run
Linux on it. There’s no denying M1 hardware is
amazing, but the idea of being entirely at the
mercy of whatever Apple decides to do with the
firmware and boot process seems like a terrible
place to be in. That being said, few people will
care about that possible issue, and for them, this
is great news.
# ⚓ uni Toronto ☛ Some_notes_on_Linux’s_/proc/locks_listing_of
file_locks⠀⇛
As covered in the proc(5) manual page, /proc/locks
lists current flock(2) and fcntl(2) file locks (and
also lockf(3) locks, because those are actually
fcntl() locks). Unsurprisingly, this /proc file is
the fundamental source of information used by
lslocks(8), and so understanding what appears in /
proc/locks and what doesn’t can tell you something
about what lslocks can show you.

# ⚓ ID Root ☛ How_To_Install_Mirage_on_Ubuntu_20.04_LTS_–
idroot⠀⇛
In this tutorial, we will show you how to install
Mirage on Ubuntu 20.04 LTS. For those of you who
didn’t know, Mirage is an open-source application
that is used to view photos on Linux systems. The
graphical user interface enables the users to view
the images easily. The Mirage, you have many
options. Includes the ability to crop the image,
resize it or change the color saturation.
Furthermore, it automatically detects all the
images found in the directory and displays them in
the side panel.
This article assumes you have at least basic
knowledge of Linux, know how to use the shell, and
most importantly, you host your site on your own
VPS. The installation is quite simple and assumes
you are running in the root account, if not you may
need to add ‘sudo‘ to the commands to get root
privileges. I will show you the step-by-step
installation of the Mirage image viewer on Ubuntu
20.04 (Focal Fossa). You can follow the same
instructions for Ubuntu 18.04, 16.04, and any other
Debian-based distribution like Linux Mint.
# ⚓ HowTo Forge ☛ How_to_Install_Chatwoot_Messaging_Platform_on
Debian_11⠀⇛
Chatwoot is a free, open-source, and real-time
messaging platform. It provides a simple and live
chat for your website and integrates it with other
apps. It helps your businesses to provide good
customer support to their clients via social media
channels. It can be easily integrated with social
media apps including, Facebook, WhatsApp, and
Twitter. It is a very good alternate solution to
other commercial software like Intercom, Zendesk,
etc.
# ⚓ Finally⠀⇛
I gave up on WordPress for my personal blog,
because after all of that effort and time spent
yesterday, I have nothing to show for it. The site
still was not rendering correctly. On the upshot, I
discovered something called Hugo which generates a
static site and I found the perfect theme for me
called beautiful hugo. It is exactly the minimalist
approach I am looking for an does not require a
whole lot of resources to run. This is just a first
post to put something up. There will be more to
come soon.
# ⚓ Vermaden ☛ ZFS_Compatibility⠀⇛
The best free filesystem on Earth – ZFS – also
often named OpenZFS recently – has also become very
portable in recent years of its development. The
OpenZFS Distributions page lists 6 (six) operating
systems already.
[...]
… but if you would like to create a ZFS pool
compatible with all of them … which options and ZFS
features should you choose? There is OpenZFS
Feature Flags page dedicated exactly to that topic.
# ⚓ Heap_Overflow_in_OpenBSD’s_slaacd_via_Router
Advertisement⠀⇛
In this blog post we analyze a heap overflow
vulnerability we discovered in the IPv6 stack of
OpenBSD, more specifically in its slaacd daemon.
This issue, whose root cause can be found in the
mishandling of Router Advertisement messages
containing a DNSSL option with a malformed domain
label, was patched by OpenBSD on March 21, 2022. A
proof-of-concept to reproduce the vulnerability is
provided.
o § Games⠀➾
# ⚓ Techdirt ☛ More_Gaming_For_Good:_Charity_Bundles,_Fortnite
Team_Up_To_Raise_Millions_For_Ukraine⠀⇛
Once again, here comes the video game industry to
do good in the world. Despite being the easy
villain for many, including grandstanding
politicians, video games and their communities can
often be seen doing good for the world. A couple of
weeks back, we discussed how one itch.io game
bundle was offering thousands of dollars worth of
games in a bundle that had over 1,000 titles to
raise money for charities supporting Ukrainians.
Despite a minimum price of $10 in a “pay what you
want” format, that bundle had already raised $2
million from a $100k goal and was then aiming at $4
million instead.

# ⚓ Make Use Of ☛ Is_Chrome_OS_Desktop_Linux?_8_Points_to
Consider⠀⇛
Do Chromebooks run Linux? This isn’t the way
they’re advertised, for sure. Google doesn’t
tell you Chromebooks come with Linux. They
run Chrome OS, Google’s take on what a
desktop operating system can be.
But despite how different Chrome OS looks and
feels, Chrome OS is based on Linux. So when
we talk about Linux, are we also talking
about Chrome OS? Here are eight points to
consider.

Pinephone_Pro,_Librem_5,_Pixel_3a⠀⇛
Capyloon is an experimental Web-based OS
leveraging b2gOS that served as the base for
the now-defunct Firefox OS. The developers’
goal is to provide an open-source OS
improving privacy and user control through
web technologies.
It’s still early stage, and some of the
technologies used include the IPFS protocol,
WebAssembly plugins, and the Tor network.
Capyloon is more like a new phone shell as it
replaces Phosh when installing it in a Linux
smartphone.

# § FSF⠀➾
# ⚓ SDTimes ☛ Free_Software_Foundation_award_winners⠀⇛
The winners of Free Software Foundation’s
2021 Software Awards for achievements in the
field of free software, are SecuRepairs, Paul
Eggert, and Protesilaos Stavrou.
SecuRepairs was the winner of the Award for
Projects of Social Benefit, which is
presented to a project or team responsible
for applying free software, or the ideas of
the free software movement to benefit
society.
SecuRepairs helps to provide factual advice
on information security issues like data
privacy as they pertain to repairing devices
and software, and works to help combat the
anti-right-to-repair narrative spread by
certain large hardware manufacturers.
# § Programming/Development⠀➾
# ⚓ Swapping_two_Numbers_without_Temporary_Variables⠀⇛
Please never use this in any production code.
The less we have to think about a piece of
code, the better it is. It’s a fun thought
experiment nevertheless!
o § Standards/Consortia⠀➾
# ⚓ Hackaday ☛ High_Noon_For_Daylight_Savings_Time⠀⇛
The US Senate has approved the “Sunshine Protection
Act”, a bill to make Daylight Saving time the
default time and do away with the annual time
changes. While I can get behind the latter half of
this motion, redefining Daylight Saving time as
Standard time is, in my opinion, nonsense.
# ⚓ Patrick Breyer ☛ DMA:_European_Pirates_celebrate_success
with_interoperability_requirements_in_final_trilogue
results⠀⇛
The Pirates in the European Parliament welcome the
final trilogue outcome of the Digital Markets Act
(DMA) that was negotiated yesterday.
Representatives of the EU Parliament, the Council
and the Commission have agreed on including
interoperability requirements for messaging
services. According to Pirates, this will allow
more choice for users, who will no longer be forced
to use multiple platforms for private messenger
communication.
* § Leftovers⠀➾
o ⚓ Vice ☛ How_Is_There_Already_So_Much_‘Elden_Ring’_Porn?_We_Asked
the_People_Who_Made_It⠀⇛
Elden Ring, one of the biggest games to launch this year,
about being a miserable wandering maidenless wretch of a
Tarnished on a Lord of the Rings type mission, is no
exception. The [Internet] is already filled with high
quality 3D Elden Ring porn. Who’s making it, and how are
they doing it so fast?
o ⚓ The Register UK ☛ China’s_annual_parliament_gives_tech_industry
much_to_ponder⠀⇛
China is this week staging its annual “Two Sessions”
meetings, which see its pair of top decision-making
bodies meet to set the agenda for the coming year. As
usual there is plenty of material that touches on tech.
The two bodies are the National People’s Congress – a
body of people installed by the Chinese Communist Party
that is technically a parliamentary body but never votes
against the Party’s wishes – and the National Committee
of the Chinese People’s Political Consultative
Conference. The latter is akin to the UK House of Lords
or US Senate in that it has an oversight role.
Premier Li Keqiang delivered the Two Sessions’ first big
set piece on Saturday, in the form of the “Report on the
work of the government”. Li emphasised increased adoption
of digital government services, more 5G, and many more
efforts to digitise many aspects of China’s society and
economy. The importance of improving China’s ability to
develop semiconductors, software, and AI was also
highlighted. Those plans have been aired before, but Li
this year said China’s government will “strengthen
overall planning” of digitization initiatives, suggesting
an acceleration.
o § Education⠀➾
# ⚓ The Nation ☛ What_I_Learned_About_Standardized_Testing⠀⇛
In June 2018, I heard that then-Mayor Bill de
Blasio wanted to do away with the Standardized High
School Admissions Test (SHSAT)—the exam New York
City students take to get into one of eight
specialized high schools. These specialized schools
are seen as huge stepping stones into elite
colleges.
# ⚓ Daniel Miessler ☛ How_to_Disagree⠀⇛
Paul Graham has a great piece on how to disagree
with people in the best possible way.
He provides a hierarchy, with 7 being best: [...]
# ⚓ Reuters ☛ Taliban_orders_girls’_high_schools_to_remain
closed,_leaving_students_in_tears⠀⇛
The last time the Taliban ruled Afghanistan, from
1996 to 2001, they banned female education and most
employment.
# ⚓ India ☛ Hijab_Row:_TNTJ_Issues_Death_Threats_To_Karnataka
HC_Judges_Over_Case_Verdict⠀⇛
He also informed that Campus Front of India (CFI),
the student wing of Popular Front of India, said
that HC’s decision stands against the Constitution
and they will continue to fight against it.
Additionally, Amir-e-Shariat an Islamic
organisation gave a bandh call against the Court’s
verdict, Bhardwaj said.
# ⚓ The Economist ☛ “A_library_is_more_powerful_than_Putin’s
aeroplanes”⠀⇛
The museum’s collection spans the 12th to the 20th
centuries, a period during which Lviv was part of
the Mongol empire, Poland, the Austro-Hungarian
empire, Imperial Russia, Poland again then, after
the second world war, the Soviet Union. The city’s
rich history is reflected in its architecture:
Renaissance palaces mingle with baroque churches
and neoclassical façades in ice-cream colours. The
city has a strong intellectual tradition. Over the
centuries it has been a hub for mathematicians,
scientists and philosophers.
o § Hardware⠀➾
# ⚓ Hackaday ☛ Polar_Planimeter_Quantifies_Area_By_Plotting
Perimeter⠀⇛
These days it’s hard to be carry the label “maker”
or “hacker” without also being proficient in some
kind of CAD- even if the C is for Cardboard. But
before there was CAD there was Drafting and its
associated arts, and one couldn’t just select a
shape and see its area in the square unit of your
choice. So how could an old school draftsman figure
out the area of complex shapes? [Chris Staecker]
introduces us to the polar planimeter, a measuring
tool created specifically for the purpose and
explained in full in the video below the break.
# ⚓ Hackaday ☛ Get_GitHub_Tickets_IRL_With_A_Raspberry_Pi_And_A
Receipt_Printer⠀⇛
Thermal receipt printers are finding their way into
all sorts of projects that are well beyond the
point-of-sale environment that they normally
inhabit. And while we applaud all the creative and
artistic uses hackers have found for these little
gems, this GitHub physical ticket printer has to be
the best use for one yet.
# ⚓ Hackaday ☛ DIY_Prony_Dyno_Properly_Displays_Power
Production⠀⇛
When hackers in the US think of a retailer called
Harbor Freight, we usually think of cheap tools,
workable but terrible DVM’s, zip ties, and tarps.
[Jimbo] over at [Robot Cantina] looked at the 212cc
“Predator” engine that they sell and thought “I bet
I could power my Honda Insight with that.” And he
did, successfully! How much power did the heavily
modified engine make? In the video below the break,
[Jimbo] takes us through the process of measuring
its output using a home built dyno.
# ⚓ Hackaday ☛ DIY_SLS_3D_Printer_Getting_Ready_To_Print⠀⇛
Ten years ago the concept of having on our desks an
affordable 3D printer knocking out high quality
reproducible prints, with sub-mm accuracy, in a
wide range of colours and material properties would
be the would be just a dream. But now, it is
reality. The machines that are now so ubiquitous
for us hackers, are largely operating with the FDM
principle of shooting molten plastic out of a
moving nozzle, but they’re not the only game in
town. A technique that has also being around for
donkeys’ years is SLS or Selective Laser Sintering,
but machines of this type are big, heavy and
expensive. However, getting one of those in your
own ‘shop now is looking a little less like a dream
and more of a reality, with the SLS4All project by
[Tomas Starek] over on hackaday.io.
# ⚓ Hackaday ☛ A_Robot_Game_To_Open_Your_Hackerspace⠀⇛
It’s always good to welcome a new hackerspace to
the fold, and thus we’re pleased to hear about the
upcoming opening of Hackerspace Drenthe, on the
north-eastern edge of the Netherlands. Starting a
new space during a global pandemic is something of
a feat. As part of their opening something is
required to demonstrate a robot for the curious
public, and what could be more accessible than a
robot arm playing tic-tac-toe!
# ⚓ Hackaday ☛ Hackaday_Podcast_161:_Laser_Lithography,
Centurion_Hard_Drive,_And_Mad_BGA_Soldering⠀⇛
Join Hackaday Editor-in-Chief Elliot Williams and
Staff Writer Dan Maloney for an audio tour of the
week’s top stories and best hacks. We’ll look at
squeezing the most out of a coin cell, taking the
first steps towards DIY MEMS fabrication, and
seeing if there’s any chance that an 80’s-vintage
minicomputer might ride again. How small is too
small when it comes to chip packages? We’ll find
out, and discover the new spectator sport of
microsoldering while we’re at it. Find out what’s
involved in getting a real dead-tree book
published, and watch a hacker take revenge on a
proprietary memory format — and a continuous
glucose monitor, too.
# ⚓ SparkFun Electronics ☛ Arm_Opens_Innovation_Lab_in_South
Africa⠀⇛
Arm is opening a new pilot innovation and
demonstration (E3)NGAGE lab in partnership with the
Cortex Hub, a regional technology incubator located
in East London, Eastern Cape, South Africa. The lab
will focus on engaging, educating and catalyzing
local technology ecosystems while making Arm the
computing foundation across the region.
# ⚓ The Register UK ☛ Intel_axes_older_FPGA_cards,_moves
development_to_customers_•_The_Register⠀⇛
Intel is discontinuing its original lineup of
Programmable Acceleration Cards as it turns to an
“ecosystem first” strategy that helps customers
create their own FPGA-based products, including
SmartNICs.
The chipmaker issued an end-of-life notice
Wednesday for three products in its FPGA-powered
Programmable Acceleration Card lineup that debuted
in 2017: the Intel PAC with Intel Arria 10 GX FPGA,
the Intel FPGA PAC N3000, and the Intel FPGA PAC
D5005.
Intel is ending production of the cards “due to
product transition and declining demand,” and
customers have until July 11 to order them, the
notice said. The final shipments will go out March
10, 2023, though Intel warned it can’t guarantee
delivery for last-time orders “due to the
unprecedented global demand for and limited supply
of semiconductor components and substrates.”
o § Health/Nutrition/Agriculture⠀➾
# ⚓ Common Dreams ☛ Opinion_|_Will_Privatization_Force
Traditional_Medicare_Out_of_Business?⠀⇛
Five or ten years from now, seniors may wake up one
morning and discover that their beloved Medicare
program has been completely privatized. And it will
not be because that’s what seniors want; it will be
due to corporate influence and profiteering.
Medicare was not created as a private program. In
fact, it was enacted in 1965 as federal health
insurance for seniors because many private
insurers refused to cover them. But over the past
three decades, insurance companies and private
investors have found a way to capture a growing
share of federal Medicare dollars—money that should
go toward patient care, not corporate profit.

# ⚓ TruthOut ☛ Our_Governments_Have_Chosen_Capitalism_Over
Preparing_for_Next_COVID_Surge⠀⇛
# ⚓ Orac ☛ Autopsies_for_everyone_will_end_vaccine
misinformation_immediately?⠀⇛
Although I had mentioned him before, first time I
dedicated a post to discussing Steve Kirsch, the
tech bro who started out the pandemic two years ago
as somewhat reasonable in his desire to fund
research into repurposed drugs to treat the COVID-
19 who later turned ivermectin zealot,
misinformation firehose, and outright antivaxxer,
it was about his “secret plan to end the vaccine
madness.” More recently, he’s been whining that no
one will “debate” him while harboring the apparent
delusion that a free-for-all five hour video debate
between him and his pseudoexperts versus real
experts will end vaccine hesitancy, while
complaining about “censorship.” (Of course, what he
views as censorship I view as quality control.)
Given Kirsch’s history of hare-brained schemes to
“end vaccine hesitancy” or “end COVID-19
misinformation,” I was somewhat amused at his
latest proposal; that is, until I realized that
some people might wonder why it’s not a good idea.
His proposal was published on his Substack earlier
this week under the title—yawn, again?—A simple way
to end vaccine misinformation immediately. The way?
Kirsch thinks that an autopsies will do the trick,
but not just any autopsies, rather:
# ⚓ Counter Punch ☛ Two_Years_in_and_We_Still_Need_to_Learn_the
Lessons_of_This_Pandemic⠀⇛
A global pandemic had reached the United States and
changed each of our lives in ways we never
imagined. Millions of Americans would lose jobs,
friends, family, and even their lives to COVID-19,
while billionaires would see record increases in
their wealth.
While the country ground to a halt, and I googled
whether an imam would perform our marriage over
Zoom, there was a glimmer of hope at the back of my
mind. Surely, I thought, an event so monumental —
one that laid bare every inequity of our economic
system — would call for a change of equal measure.
# ⚓ Pro Publica ☛ State_Launches_Cancer_Study_After_ProPublica
Identifies_Toxic_Air_Pollution_Hot_Spot⠀⇛
After learning from a ProPublica analysis that his
Missouri city is a hot spot of toxic air pollution,
Verona Mayor Joseph Heck demanded that government
officials look into the local cancer rate.
Three months later, the state health department
confirmed his fears: The rate of Non-Hodgkin
lymphoma in the Verona zip code is more than twice
as high as that of the surrounding county and
state, officials told him. Non-Hodgkin lymphoma, a
cancer that begins in the lymphatic system, can be
caused by exposure to ethylene oxide, a potent
carcinogen released by the BCP Ingredients plant in
Verona. ProPublica’s unique analysis of air
pollution data from the Environmental Protection

According to Mark Gurman at Bloomberg, Apple
has been working on a new subscription

products that will let customers subscribe to
Apple hardware with a monthly recurring
payment. According to Gurman’s sources, Apple
has been working on the subscription program
for several months and is expected to launch
it at the end of 2022.
Unfortunately, that’s all the detail we have
right now. We don’t know anything about
pricing, bundles, which Apple hardware would
be offered (other than the iPhone), or terms
for trade-ins and upgrades. Apple already
offers the iPhone Upgrade Program in the

after 12 months.

According to Bloomberg’s report, the monthly

be a still-undecided monthly cost,
potentially with the option to upgrade to new
hardware as its released. And like Apple’s

possibility of bundling in AppleCare or Apple

But if we look at a larger map that includes not

from Turkey to Somalia and Yemen.
Parallels are occasionally drawn between the
Ukrainian war and a dozen or so conventional and
guerrilla wars being fought out in this vast area
of conflict to the south of Ukraine. When
similarities between these conflicts are noted, it
is usually on the grounds that Russian shelling and

imagines plotters behind every curtain (which is
where the assassins of Tsar Paul I found him hiding

Putin’s self-imposed isolation can only mean that
he’s cut off from his commanders in the field, as

For many of these countries, Moscow’s attack on
Ukraine does not look any different from
Washington’s 2003 attack on Iraq. They stayed out
of that and are staying out of this, despite the
wall-to-wall coverage, the comparisons to Pearl
Harbor and the media frenzy over this assault on a
country whose citizens are white (and therefore
apparently deserve more compassion than the
millions of non-European Afghans starved by U.S.
sanctions or the over 377,000 brown Yemenis
slaughtered with U.S. weapons), with breathless
claims that nothing like this has happened in
Europe since World War II. Our propaganda outlets
that call themselves media have apparently
forgotten NATO’s 1999 bombing of Yugoslavia. For
some unexplained reason, that didn’t count. Except
of course to the Serbs – another demonized ethnic
group, though I doubt their magnificent composers
were banned from the repertoires of western
orchestras, that their conductors and sopranos were
ordered to revile their country or be fired or that
their immortal novelists, like Dostoevsky, were
deleted, if temporarily, from curricula at the
University of Milan.
There’s nothing easier than denouncing a national
enemy. More arduous is attempting to regard
something objectively awful – the Russia/Ukraine
war – with clear eyes and without succumbing to the
required Two Minutes Hate. Few do that in the west.
Any western news report, any politician’s speech,
even casual conversation about this conflict zooms
quickly to Two Minutes Hate. Furious tirades
against Moscow and Putin explode everywhere, are
the norm, expected and those who don’t indulge thus
are suspect at the least and very likely considered
treasonous. Nothing nowadays comes more naturally
or facilely than this western and European hatred
of all things Russian. But that is not the case in
the Global South.

I doubt the people saying “stop worrying about

nuclear winter in October of 1962, when John
Fitzgerald Kennedy decided to turn Soviet missiles
sent to protect socialist Cuba from further U.S.
invasions into a game of nuclear chicken. On
October 27, 1962, Soviet submarine Second Captain
Vasily Arkhipov’s refusal to agree with his
Captain’s decision to assemble and launch a nuclear
torpedo at US destroyers in the Saragossa Sea may
well have saved humanity from annihilation. At the
time, one-third of the United States’ nuclear bomb-
carrying Air Force fleet was in the air at “Defcon

to rage for years, killing about 400,000 people.

The horrible paradox is that, though Bolsonaro’s

(the operative word) a very effective kind of
political communication or, better said,
propaganda. This kind of fake news provides a cover
of white noise that’s so stupefying it’s impossible
to see behind it. Nevertheless, if it’s difficult
to produce direct evidence that the Bolsonaro
government is committing a whole range of heinous
crimes, we can state that the militia gangs that
have been associated with the Bolsonaro family for
years are engaged in drug trafficking, arms deals,
and assassinations, creating a climate of fear
which, duly disseminated, is the perfect medium in
which such a regime can operate, especially with
help from the new “digital militia”.
Bolsonaro’s murderous antics are more than
diversionary tactics from the real business of his
shambles of a regime dominated by the interests of
the bullet-beef-and-bible lobby, which is all about
agribusiness (read: razing the Amazon), “family
values” (read: extreme homophobia and hatred of all
sexual and reproductive rights), and trigger-happy
paramilitaries (read: narco-militia), a foul mix of
drug traffickers, paramilitary forces, and neo-
Pentecostal churches waging a holy war, some under
an Israeli flag and with a copy of the Torah,
against rival criminal groups and Afro-Brazilian
religions. It’s not just about a bunch of Brazilian
fanatics. No corner of the Earth is free of the
politics of hate and fear which pervades almost all
aspects of social life. Everyone’s affected, one
way or another. In the case of Brazil, Bolsonaro
and his henchmen present themselves as patriotic
heroes when they’re blatantly committing lese-
patria at the service of local racketeers and
international corporations. This atrocious mix of
ecocide, genocide, religion justifying deadly
intolerance, and drug trafficking, all dressed up
as “government”, does one’s head in when trying to
understand the connections, the twists in the lies,
or how a man like Bolsonaro can get away with
political spectacles that as well as being morally
repugnant are insulting to the intelligence. At
this point we’d like to cite the whole of Guy

The combination of Covid, the costs of the green

prices), and the damage caused by the Russian
invasion of Ukraine have already brought Hungarian
economic policy to its knees. The disasters of

This formula to measure the efficiency of the CDS
has been in use for more than a decade, but it is
being reupped by the Biden administration. Indeed,
the CBP guide was issued just as Biden was
declaring that he would create a fair, orderly, and
humane border and immigration system. While the
administration talked about rescinding Trump
initiatives such as the Migrant Protection Protocol
(now reinstated) and was hinting that Title 42
would be stopped (it’s still in effect), the CDS
and the more long-term deterrence strategies have
continued on without much comment. And its policies
and infrastructure of incarceration, which for
decades has led families to be arrested, detained,
and separated, lurks below the dominant rhetoric,
particularly that of the White House.
Behind closed doors, agents, like technocrats in a
Fortune 500 company, create color-coded graphics to
demonstrate the most “efficient” and “effective”
enforcement techniques. Even though the
effectiveness of deterrence has been questioned and
refuted, and even though the question of human
rights has not entered the equation at all, the
U.S. federal government seems to be plowing ahead
with this without any questions.

# ⚓ Techdirt ☛ On_Elon_Musk_And_Free_Speech⠀⇛
Let’s start this off by noting that I actually
think that Elon Musk sometimes receives both too
much criticism from some circles and too much
praise from others. I think he deserves tremendous
praise for taking visions that, at the time, seemed
nearly impossible, and then making them real. From
electric vehicles with Tesla, to space flight with
SpaceX, it’s unquestionable that he’s driven
tremendous innovation. And even in areas like
Starlink, which has been unfortunately overhyped,
he deserves kudos for actually building a working
(if somewhat limited) satellite internet service.
And that’s not even getting into his various
efforts with trying to create a hyperloop, or
trying to deal with transportation issues via The
Boring Company. Again, some of these have been
massively overhyped, but Musk, unlike many others,
gets a vision and then acts on it, and I find that
commendable — and helpful in driving innovation
forward.

To this point on November 22, 2021, the
International Institute for Democracy and Electoral

released its 2021 Report on “The Global State of
Democracy.[1] The report’s introduction begins with
these chilling statements. “Democracy is at risk,”
“Its survival is endangered by a perfect storm of
threats, both from within and from a rising tide of
authoritarianism.” “The world is becoming more
authoritarian as nondemocratic regimes become even
more brazen in their repression, and many
democratic governments suffer from backsliding by
adopting their tactics of restricting free speech
and weakening the rule of law.”
Indeed, the annual report from Freedom House
reports that freedom around the world declined in
2021 for the 16th consecutive year, that China and
Russia are exporting authoritarianism, that
undemocratic regimes are growing more so, and that
even in established democracies, like the U.S.,
“internal forces have exploited the shortcomings of
their systems, distorting national politics to
promote hatred, violence and unbridled power.” Over
the past year, 60 countries became less free, while
only 25 improved.[2] 38% of the global population
live in countries that are not free (the highest
since 1997); 20% live in free countries; and 42%
live in “partly free” countries. Sadly, the United
States falls within this last category.[3]

The debate over the degree of flexibility at
the disposal of national courts in Europe to
grant, deny, or tailor, injunctive relief in
patent litigation seems to be a never-ending
story. In most jurisdictions, absent
exceptional circumstances, findings of
infringement lead national courts to grant,
quasi-automatically, an injunction. However,
some scholars as well as industry players,
have argued that in light of recent changes
in litigation behaviour as well as technology
developments, a general principle of
proportionality should play a more prominent
role vis-à-vis injunctive relief. It is in
particular with reference to Art. 3(2) of the
Enforcement Directive that such claims have
been made. If UK courts have been inclined to
consider that, under certain circumstances, a
balance of interests may take place before
granting a permanent injunction, German
courts on the other hand have firmly stood on
the ground that the principle of
proportionality should not interfere with the
right of patent holders to obtain such
remedy. However, most recently, the German
Ministry of Justice published a draft
amendment to the German Patent Act providing
some guidance on the role of proportionality
vis-à-vis the rules of injunctive relief. The
issue of flexibility and injunctive relief is
symptomatic of a broader debate regarding
potential over-enforcement practices by right
holders and the means to overcome or reduce
the negative effects of these practices.
Overall, this article examines how the
origins and justifications of the Enforcement
Directive, which focus on fighting piracy and
counterfeiting, may affect the applicability
of the principle of proportionality in the
ever-changing context of patent law. How
national courts have (or have not) relied on
different mechanisms to infuse more
flexibility in case of over-enforcement
practices by right holders. And finally, how
the principle of proportionality as well as
the principle of the prohibition of abuse of
rights may serve national courts in this
endeavour of limiting excesses in patent
litigation.
# ⚓ EFF ☛ Defend_Innovation⠀⇛
The result is Defend Innovation: How to Fix
Our Broken Patent System, a whitepaper
providing a comprehensive view of the issues
plaguing the patent system today, as well as
a series of solutions that Congress, the
Patent Office, the courts, and companies can
implement.

# ⚓ Torrent Freak ☛ Court:_Null-Routing_is_Not_a
Practical_Anti-Piracy_Measure⠀⇛
A federal court in Florida maintains that
there is no reason to believe that hosting
company Quadranet is liable for the pirating
activities of its VPN customers. A group of
filmmakers suggests that the provider could
have null-routed IP-addresses, but the court
doesn’t see this as a practical or effective
measure.
# ⚓ Torrent Freak ☛ Pirate_IPTV_Services_Disrupted_By
Dozens_of_Rightsholders_On_Multiple_Fronts⠀⇛
Rightsholder measures against pirate IPTV
providers, sellers and resellers are nothing
new but in the last week alone, numerous
actions have come to fruition in a number of
regions. Whether in Canada, the Netherlands,
France or the UK, life is getting just that
little bit harder for those in the pirate TV
business.

Summary: From the_official_talk‘s description: “Many communities have widely
adopted codes of ethics governing the moral conduct of their members and
professionals. Some of these codes may even be enshrined in law, and for good
reason—certain conduct can have enormous consequences on the lives of others.”

http://techrights.org/videos/office-move.webm
Summary: Today I moved to a more spacious desk and added a bunch of equipment
to compensate for a failing SSD
TODAY was a very unusual day. None of this was planned, but a solution for the
failing SSD was long overdue. I took precautionary measures to avoid
catastrophic data loss, but short of literally replacing the storage nothing
would work properly. Postponing and procrastinating was a disaster waiting to
happen. I also needed quite a lot of storage, so I ended up buying a low-budget
machine, cobbling together all the machines from noon till evening time, taking
the opportunity to also turn the dining room into an office, which is generally
a lot safer as there’s no carpeting. There will be several practical benefits
in the long run and at the moment I control 9 screens and 6 computers with one
mouse and one illuminated (external) keyboard that I’m accustomed to. It is
mechanical. Tomorrow will be a very busy day because of data migration, so I
don’t anticipate much output. Today was a long-term investment that can pay off
for months to come.
Incidentally, today I finally became a KDE Neon user. I was always intrigued by
and curious about this distro, now I can warmly recommend it to KDE lovers. I
also really liked Linux Mint Debian Edition, which is only days old. Shame on
Mozilla for turning Firefox into adware; I hadn’t imagined it would get this
bad. I think several distros should consider making Falkon or LibreWolf the
default Web browser. █

* Leftovers
* § GNU/Linux⠀➾
o § Desktop/Laptop⠀➾
# ⚓ Unix Men ☛ How_Businesses_Can_Benefit_from_Using_Linux⠀⇛
Many businesses spend a lot of time weighing up the
benefits of cloud automation and orchestration,
without spending too much time considering
operating systems. Historically, Microsoft Windows
has been the OS of choice. However, when it comes
to hosting services, Linux is definitely the better
option.
o § Audiocasts/Shows⠀➾
# ⚓ Video ☛ ProtonDB_Has_A_New_Linux_Game_Ranking_System_–
Invidious⠀⇛
ProtonDB is an incredible website to check the
state of Linux gaming but recently it received a
massive change and ruined the site but now it has
been redesigned and in many ways is better than
ever
# ⚓ Video ☛ I_Need_More_Audio_Jacks_On_My_Computer_–
Invidious⠀⇛
I’ve got a problem. I’ve got multiple sets of
speakers and headphones that I switch between, and
I’m tired of having to constantly plug/unplug stuff
into the one 3.5mm jack on the back of my computer.
# ⚓ Video ☛ My_New_Linux_Desktop_–_Material_Shell_–_Invidious⠀⇛
This is an absolutely amazing desktop experience.
By far one of my favorites, because we revisit one
of my favorite layouts and developers of modern UI
interfaces.
o § Kernel Space⠀➾
# ⚓ Asahi_Linux_Is_Reverse-Engineering_Support_For_Apple
Silicon,_Including_M1_Ultra⠀⇛
For months, a small group of volunteers has worked
to get this Arch Linux-based distribution up and
running on Apple Silicon Macs, adapting existing
drivers and (in the case of the GPU) painstakingly
writing their own. And that work is paying off —
last week, the team released its first alpha
installer to the general public, and as of
yesterday, the software supports the new M1 Ultra
in the Mac Studio. In the current alpha, an
impressive list of hardware already works,
including Wi-Fi, USB 2.0 over the Thunderbolt ports
(USB 3.0 only works on Macs with USB-A ports, but
USB 3.0 over Thunderbolt is “coming soon”), and the
built-in display. But there are still big features
missing, including DisplayPort and Thunderbolt, the
webcam, Bluetooth, sleep mode, and GPU
acceleration. That said, regarding GPU
acceleration, the developers say that the M1 is
fast enough that a software-rendered Linux desktop
feels faster on the M1 than a GPU-accelerated
desktop feels on many other ARM chips.
o § Applications⠀➾
# ⚓ Make Use Of ☛ Why_Run_Windows_Apps_on_Linux?_Here_Are_15
Linux_Alternatives⠀⇛
As you might have noticed, more and more people are
switching to Linux these days. However, it is still
pretty common for Linux users to look for apps they
are used to using on Windows.
If you want to enjoy the Linux experience to the
fullest, we recommend switching to Linux apps to
perform your day-to-day tasks. That’s how your
journey will come full circle.
So, to aid you in this process, here is a list of
Linux alternatives to popular Windows apps that you
can download and use for free.
o § Instructionals/Technical⠀➾
# ⚓ DT ☛ Upgrade_PostgreSQL_Database_(Cluster)_from_one_Major
Version_to_Another⠀⇛
I’m in the process of finally upgrading my Debian
install from oldstable (buster) to stable
(bullseye). My DAViCal installation uses PostgreSQL
for its database backend. Strangely, I have two
versions of PostgreSQL (9.6 and 11) and I purged
the older one (without deleting the databases,
thankfully).
# ⚓ ID Root ☛ How_To_Install_ExifTool_on_Ubuntu_20.04_LTS_–
idroot⠀⇛
In this tutorial, we will show you how to install
ExifTool on Ubuntu 20.04 LTS, as well as some extra
required packages by ExifTool
# ⚓ Streaming_the_Steam_Deck_to_OBS⠀⇛
Valve was kind enough to send Steam Deck devkits to
Arch Linux maintainers and developers which gave us
an opportunity to mess around with the device.
Personally I find it a bit fun to mess around with
video streaming, thus one of the first things I
wanted to try figure out was how I could stream the
gamemode on the Steam Deck. Installing the OBS
flatpak and adding it to the menu doesn’t actually
work so we sadly have to be a bit more clever.
# ⚓ Ubuntu_22.04_Chromium_Browser_installation⠀⇛
The purpose of this tutorial is to show how to
install the Chromium web browser on Ubuntu 22.04
Jammy Jellyfish. Chromium is an open source browser
maintained by Google. Along with the Chromium
browser itself, Google Chrome, Microsoft Edge,
Opera, Vivaldi, and a slew of other notable web
browsers are all based on the Chromium source code.
It’s safe to say that Chromium plays a huge role in
the way that many users view the web today.
# ⚓ How_to_set_browser_environment_variable_on_Linux⠀⇛
The purpose of this tutorial is to show how to set
the web browser environment variable on Linux.
Setting environment variables is usually how users
can set the default applications and programs used
on their Linux system. Therefore, the browser
environment variable should point to the user’s
desired default web browser.
In the case of a default web browser, this setting
is best configured by the GUI itself. Simply
setting the $BROWSER variable is not going to give
you the the result you are expecting. Manually
setting the web browser environment variable
through other means is possible, but the process
for doing so will vary across distributions and
desktop environments.
# ⚓ How_to_set_or_change_boot_partition_flag_on_Linux⠀⇛
The boot partition flag is used to indicate that an
MBR partition is bootable. Although MBR has been
superseded by GUID Partition Table in recent years,
MBR is still very prevalent across many systems.
The boot loader resides on a bootable partition and
is what tells your system where to look for the
operating system.
In this tutorial, you will find the step by step
instructions to set or change the boot partition
flag on a Linux system via command line and GUI.
# ⚓ Install_Couchbase_Server_on_Debian_11/Debian_10_–
kifarunix.com⠀⇛
In this tutorial, you will learn how to install
Couchbase Server on Debian 11/Debian 10. According
to the documentation, Couchbase Server is an open
source, distributed, JSON document database. It
exposes a scale-out, key-value store with managed
cache for sub-millisecond data operations, purpose-
built indexers for efficient queries, and a
powerful query engine for executing SQL-like
queries.
# ⚓ ByteXD ☛ How_to_Install_KDE_Plasma_or_Kubuntu_in_Ubuntu
22.04_or_20.04_–_ByteXD⠀⇛
The KDE desktop environment is called KDE Plasma,
and also referred to as Plasma Desktop.
It’s one of the most popular desktop environments,
is very intuitive and easy to use, is available in
many languages, and provides a consistent user
experience across a wide range of devices.
The KDE Plasma is also one of the most feature rich
and customizable desktop environments, and it has a
very modern look and feel.
# ⚓ MakeTech Easier ☛ How_to_Use_WhatsApp_Web_on_Desktop_and
Chrome_–_Make_Tech_Easier⠀⇛
If you have particularly chatty people on your
WhatsApp list, you’ll know how annoying it can be
to converse with them using a mobile keyboard. You
can’t really get the gossip grapevine (or more
important messages) going at a measly 20 words-per-
minute. Thankfully, there is a way to use WhatsApp
on your PC, so you can type with your hardware
keyboard and really express yourself.
# ⚓ How_to_customize_i3status_on_Linux⠀⇛
I3 is one of the most used tiling window managers
on Linux. A tiling window manager arranges windows
in a non-overlapping way: this allows us to use
screen space efficiently, but can require a little
bit of time to get used to.
The i3 window manager on Linux is usually installed
together with the i3status utility, which can be
used to populate supported status bars with
information such as memory or CPU usage. In this
tutorial we see how to customize i3status and use
some of its modules.
# ⚓ How_to_set_alarm_on_Linux⠀⇛
Setting an alarm on Linux can be helpful to remind
you of something or act as a timer. It might also
come in handy if you take a little snooze at your
desk. In this tutorial, we will show you how to set
an alarm on Linux via command line and GUI.
# ⚓ How_To_Install_and_Run_Linux_on_Android_(With/Without_Root)
–_DekiSoft⠀⇛
Technology is moving at such a pace that users
prefer smaller handhelds as their preferred choice
of hardware. Phones have become smaller in size and
more powerful in terms of computing power. They are
more than enough capable of running a full-sized
operating system.
# ⚓ The New Stack ☛ How_to_Deploy_Kubernetes_with_Kubeadm_and
containerd_–_The_New_Stack⠀⇛
There’s no easy way to say this, but Kubernetes is
challenging. And although at one time it was
actually fairly simple to deploy a Kubernetes
cluster to bare metal (thanks, in part, to Docker),
it’s not quite as simple as it once was. To
complicate matters even further, there’s an almost
endless amount of paths to getting the platform up
and running.
# ⚓ H2S Media ☛ How_to_Install_PowerShell_on_Ubuntu_22.04_LTS
[Ed: Microsoft junk, but some people use this to migrate away
from Windows]⠀⇛
# ⚓ H2S Media ☛ Install_PowerShell_on_Debian_11_Bullseye

# ⚓ How_To_Install_OpenRGB_On_Ubuntu_22.04_|_20.04_LTS_|
Itsubuntu.com⠀⇛
How to install OpenRGB tools on Ubuntu 22.04 LTS
Jammy JellyFish or Ubuntu 20.04 LTS Focal Fossa.
# ⚓ Install_Couchbase_Server_on_Ubuntu_22.04/Ubuntu_20.04_–
kifarunix.com⠀⇛
In this tutorial, you will learn how to install
Couchbase Server on Ubuntu 22.04/Ubuntu 20.04.
According to the documentation, Couchbase Server is
an open source, distributed, JSON document
database. It exposes a scale-out, key-value store
with managed cache for sub-millisecond data
operations, purpose-built indexers for efficient
queries, and a powerful query engine for executing
SQL-like queries.
# ⚓ AddictiveTips ☛ How_to_back_up_and_restore_your_website_on
Linux⠀⇛
If you run a website on a Linux server, you should
be keeping regular backups. We’ve got you covered
if you’re new to Linux server administration.
Here’s how to back up and restore websites on
Linux.
# ⚓ ID Root ☛ How_To_Install_Passbolt_on_AlmaLinux_8_–_idroot⠀⇛
In this tutorial, we will show you how to install
Passbolt on AlmaLinux 8. For those of you who
didn’t know, Passbolt is a free and open-source
password manager based on PHP, MySQL, and OpenPGP
which allows you to securely store and share login
credentials of website, router password, Wi-Fi
password, etc. It is self-hosted and available in
both community and subscription-based editions.
This article assumes you have at least basic
knowledge of Linux, know how to use the shell, and
most importantly, you host your site on your own
VPS. The installation is quite simple and assumes
you are running in the root account, if not you may
need to add ‘sudo‘ to the commands to get root
privileges. I will show you through the step-by-
step installation of the Passbolt password manager
on an AlmaLinux 8. You can follow the same
instructions for Fedora, RHEL, CentOS, and Rocky
Linux distributions.
# ⚓ AddictiveTips ☛ How_to_set_up_a_LAMP_server_on_Debian_11⠀⇛
While many people think of Debian as a rock-solid
workstation operating system, that’s not all it can
be used for. Debian is also one of the most used
Linux-based server operating systems.
There are a lot of server applications for Debian.
However, one of the most popular things users set
up is LAMP. LAMP is Linux, Apache, MySQL, and PHP,
and it is essential for hosting web apps. Here’s
how you can set up a LAMP server on Debian 11.
o § Wine or Emulation⠀➾
# ⚓ 9to5Linux ☛ DXVK_1.10.1_Adds_Initial_Support_for_Shared
Resources,_Fixes_God_of_War_and_GTA:_San_Andreas⠀⇛
DXVK 1.10.1 is the first point release in the DXVK
1.10 stable series and it’s here to implement
initial support for shared resources in an attempt
to fix video playback for several Koei Tecmo games,
including the Atelier series and Nioh 2, as well as
the D3D11-based UI in the Windows version of Black
Mesa.
However, “initial” means that this feature is
considered experimental as it hasn’t been
thoroughly tested against all graphics drivers.
According to the release notes, only basic 2D
texture sharing between the D3D9 and D3D11
implementations is supported when using DXVK for
both APIs.
# ⚓ GamingOnLinux ☛ DXVK_1.10.1_is_out_with_initial_support_for
shared_resources_|_GamingOnLinux⠀⇛
DXVK is the free and open source project that
translates Direct3D 9 / 10 / 11 to Vulkan for use
with the Wine and Proton Windows translation
layers. One of the major parts of Steam Play Proton
that helps games run well on Linux desktops and
Steam Deck.
Version 1.10.1 brings on initial support for shared
resources, fixing video playback in a number of
Koei Tecmo games (Atelier series, Nioh 2), as well
as the D3D11-based UI in the Windows version of
Black Mesa. It’s still quite experimental now and
needs more testing across various drivers.
o § Games⠀➾
# ⚓ Boiling Steam ☛ Steam_Starts_Collecting_Feedback_From_Users
on_Steam_Deck_Verified_titles_–_Boiling_Steam⠀⇛
Valve has just announced through the Steam
community news that they are adding a new feature
to collect feedback from end users about the Steam
Deck Verified games they try out. In practice it
will first ask you to opt-in to be part of the
feedback service, and afterwards it will ask you
questions about the titles you have just played on
the Steam Deck to confirm if it matches your
experience:
# ⚓ GamingOnLinux ☛ Syncthing_is_a_great_way_to_transfer_files
from_PC_to_Steam_Deck_|_GamingOnLinux⠀⇛
Recently I did a guide using the Warpinator tool to
transfer files from PC to Steam Deck, here’s
another way using the wonderful tool Syncthing that
you might prefer. that you might prefer.
A lot of people seemed to like the previous guide
and video, however a few people couldn’t get
Warpinator to work although most did. So as a
bonus, I checked out Syncthing to see how that
works. It’s just as easy to get going too.
# ⚓ GamingOnLinux ☛ Valve_actually_announced_Steam_for_Chrome
OS_now_too_|_GamingOnLinux⠀⇛
After a bit of a false start with an announcement
made too early, Google has now announced Steam for
Chrome OS and Chromebooks and now Valve has done
their own brief announcement. So it’s all
officially official now.
o § Desktop Environments/WMs⠀➾
# § K Desktop Environment/KDE SC/Qt⠀➾
# ⚓ Wikidata_Data_Reuse_Days_2022_Recap⠀⇛
Over the past two weeks I attended a number
of sessions of the Wikidata Data Reuse Days
2022 and presented KDE’s use of Wikidata in
our travel apps there. Here are some of the
things I found particularly interesting from
a KDE perspective.
o § Distributions⠀➾
# § IBM/Red Hat/Fedora⠀➾
# ⚓ Fedora ☛ Nest_with_Fedora_&_Fedora_Hatch:_Announcing
dates_&_call_for_volunteers⠀⇛
Hi Fedora Friends! We made it through another
year of living with COVID-19, with plenty of
other challenges added on top. To everyone
who make up Fedora – thank you for your
presence, contributions, and efforts during
this trying time. Because we have yet to see
an end to living with COVID-19, I opened a
discussion with the community about what we
should do for this year’s contributor
conference.
Based on that feedback, I am pleased to
announce that we will be holding the third
edition of Nest with Fedora on August 4th,
5th, & 6th. I will be publishing info on the
CfP in the upcoming months. We will also be
funding local in person meetups that we have
titled Fedora Hatch. If you want to
participate in an in person meetup, make sure
to read on and suggest your ideas on the
Flock pagure!
# § Debian Family⠀➾
# ⚓ Linuxiac ☛ Parrot_5.0_Released_with_Cloud_and
Customizability_in_Mind⠀⇛
From release 5.0, Parrot is also available
for Raspberry Pi 4. Without a desktop
environment, you can install whatever you
like.
Penetration testing and ethical hacking have
risen in popularity and industry needs over a
previous couple of decades. From learning
about the dangers of the internet to
protecting data from hackers, the software
industry has become increasingly aware of the
millions of dollars that could be lost in a
breach.
Similar to Kali Linux, Parrot Security OS was
created as an operating system for ethical
hackers to raise awareness even further. It
is a free and open-source Linux distribution
based on Debian.
# ⚓ Debian_—_News_—_Updated_Debian_11:_11.3_released⠀⇛
The Debian project is pleased to announce the
third update of its stable distribution
Debian 11 (codename bullseye). This point
release mainly adds corrections for security
issues, along with a few adjustments for
serious problems. Security advisories have
already been published separately and are
referenced where available.
Please note that the point release does not
constitute a new version of Debian 11 but
only updates some of the packages included.
There is no need to throw away old bullseye
media. After installation, packages can be
upgraded to the current versions using an up-
to-date Debian mirror.
# ⚓ Debian_—_News_—_Updated_Debian_10:_10.12_released⠀⇛
The Debian project is pleased to announce the
twelfth update of its oldstable distribution
Debian 10 (codename buster). This point
release mainly adds corrections for security
issues, along with a few adjustments for
serious problems. Security advisories have
already been published separately and are
referenced where available.
Please note that the point release does not
constitute a new version of Debian 10 but
only updates some of the packages included.
There is no need to throw away old buster
media. After installation, packages can be
upgraded to the current versions using an up-
to-date Debian mirror.

And back to relative normality : the usual
suspects are in Cambridge. It’s a glorious
day across the UK and we’re spending it
indoors with laptops 🄸🄼🄰🄶🄴 🄳🄴🅂🄲🅁🄸🄿🅃🄸🄾🄽 ⦇:)⦈
We’ll also be releasing a point release of
Buster as a wrap up of recent changes.
Debian 10 should move from full support to
LTS on July 14th – one year after the release
of Debian 11.
All seems to be behaving itself well.

For various obscure reasons, I have a mirror
of Debian in one room and the main laptop and
so on I use in another. The mirror is
connected to a fast Internet line – and has a
1Gb Ethernet cable into the back directly
from the router, the laptop and everything
else – not so much, everything is wired, but
depends on a WiFi link across the property.
One end is fast – one end runs like a snail.

# ⚓ Piwigo_and_Raspberry_PI:_a_Private_Open_Source_Photo
Management_Platform⠀⇛
Keeping your pictures and videos in smartphones can
suddenly drain your storage space. Piwigo with
Raspberry PI can save your space and give you more
features to manage them privately
In this tutorial, I’m going to show you how to
install Piwigo on your Raspberry PI computer board.
It can also be considered a great Google Photo
alternative, as the Google service requires a paid
subscription once you require more space. An
important thing is, after the Piwigo installation,
to use the official users manual to keep our files
secure from any outage with periodic backups.

# ⚓ Arduino ☛ Top_Three_Arduino_Cloud_Games_Projects
Revealed_|_Arduino_Blog⠀⇛
The Arduino Cloud Games was first hinted at
just after Christmas, 2021. That’s how long
these amazing members of the Arduino
community have been toiling on some genuinely
incredible projects.
The top three were just announced live on the
community day at Arduino Week 2022, so we
thought we’d give you a closer look at what
they built. Firstly though, even if it’s
something of a cliche, we’ve got to say that
picking them was insanely difficult. The
quality, imagination and skills we’ve seen
throughout the Arduino Cloud Games has been
staggering. Seriously, there are very few
people who work at Arduino that could build
such amazing things.
So if you didn’t make it into the top three,
despair not! You were up against some of the
toughest creative competition in the maker
world. You all blew our minds with every new
project that arrived on Project Hub, so you
should be incredibly proud that you made it
into the finals. Keep on building!

I recently saw @vidak@zoinks.one thinking about
setting up a server where people could host Gemini

their previous effort of building something for the
benefit of others, a tilde server. It felt like a
very familiar problem.
# ⚓ Linux Links ☛ Best_Free_and_Open_Source_Alternatives_to
Apple_Boot_Camp⠀⇛
Apple, Microsoft, Alphabet (Google’s parent),
Amazon and Facebook dominate the tech landscape.
Their dominance is so broad they account for more
than 20% of the S&P 500.
There are many things to admire about Apple’s
hardware and software. Apple make great looking
(albeit expensive) hardware. Over the years key
successes include the iPhone, iPad, iPod, and the
MacBook Air. The company designs its own hardware
and software. This gives them the power to make an
operating system and suite of apps that are tailor-
made and optimized for their hardware. Apple also
operates the Apple Music and Apple TV media
distribution platforms.
Mac OS X is Apple’s proprietary operating system
for its line of Macintosh computers. Its interface,
known as Aqua, is highly polished and built on top
of a BSD derivative (Darwin). There’s a whole raft
of proprietary applications that are developed by
Apple for their operating software. This software
is not available for Linux and there’s no prospect
of that position changing.
In 2020, Apple began the Apple silicon transition,
using self-designed, 64-bit ARM-based Apple M1
processors on new Mac computers. Maybe it’s the
perfect time to move away from the proprietary
world of Apple, and embrace the open source Linux
scene.
# § Programming/Development⠀➾
# ⚓ Linux Links ☛ 3_Top_Free_and_Open_Source_Ruby_Web
Frameworks_–_LinuxLinks⠀⇛
One of the types of software that’s important
for a web developer is the web framework. A
framework “is a code library that makes a
developer’s life easier when building
reliable, scalable, and maintainable web
applications” by providing reusable code or
extensions for common operations. By saving
development time, developers can concentrate
on application logic rather than mundane
elements.
A web framework offers the developer a choice
about how to solve a specific problem. By
using a framework, a developer lets the
framework control portions of their
application. While it’s perfectly possible to
code a web application without using a
framework, it’s more practical to use one.
Ruby is a general purpose, scripting,
structured, flexible, fully object-oriented
programming language with a focus on
simplicity and productivity. Ruby is a very
conservative language. It’s equipped with
very carefully chosen features that have been
fully tested.
When it comes to web development, there are a
fairly small range of Ruby frameworks to
choose. The choice depends on finding the
right tool for the job at hand. Here’s our
pick of the finest Ruby web frameworks.

# ⚓ The_Rhodes_Scholars_Guiding_Biden’s_Presidency⠀⇛
The recent, pandemic-ridden years have involved a
steep and often traumatic learning curve for many
citizens across the Trans Atlantic. One
particularly shocking revelation that has ripped
virally across the internet in recent days revolves
around the revelations that the World Economic
Forum’s ‘Young Global Leaders’ have been positioned
across western governments and powerful private
institutions over the past three decades.
Videos of Klaus Schwab bragging that Young Leaders
have been positioned across the governments of
Canada, Argentina, Europe and beyond are now being
posted across social media platforms on a daily
basis, confirming the suspicions of many that the
World Economic Forum is not a benign business
networking operation, as it has tried to project
for the credulous. Rather, it is something much
darker and insidious.
Set up in 1993 as the Global Leaders of Tomorrow
and renamed WEF Young Leaders Forum in 2004 (fueled
with funds from such benevolent institutions as JP
Morgan Chase and the Bill and Melinda Gates
Foundation), over 1400 young leaders (under the age
of 38) from both public and private sectors have
been processed through the program. For those
tapped to become members of this elitist clique,
they agree to attend six years of regular WEF
conferences featuring seminars, focus groups and
other special experiences both at Davos and at
regional WEF events, at which point they graduate
and become “alumni” who, in turn, become capable of
nominating future young leaders.
Just a tiny sampling of the prominent figures who
have been processed and installed into positions of
influence to advance the WEF globalist agenda over
the past 30 years include Angela Merkel, Nicholas
Sarkozy, Emmanuel Macron, Tony Blair, Mark
Zuckerberg, José Manuel Barroso, Bill Gates,
Chrystia Freeland, Pete Buttigieg, Jacinda Arden
(PM New Zealand), Jack Ma (Ali Baba founder), Larry
Fink (Blackrock CEO), Larry Page (Google founder),
Lynn Forrester de Rothschild (Council for Inclusive
Capitalism founder), Jimmy Wales (Wikipedia
founder), Peter Thiel (Paypal founder), Leonardo Di
Caprio (tool), Richard Branson (Virgin Records
CEO), Jeff Bezos (Amazon founder), Stephan Bancel
(Moderna CEO), Pierre Omidyar (Ebay co-founder),
Alizia Garza (co-founder BLM), Jonathan Soros (son
of sociopath) and, according the Schwab, himself
“half the Canadian Cabinet” under Prime Minister
Justin Trudeau.

Disassembling and analyzing malware to
see how it works, what it’s designed to
do and how to protect against it, is
mostly a long, manual task that
requires a strong understanding of
assembly code and programming,
techniques and exploits used by
miscreants, and other skills that are
hard to come by.
What with the rise of deep learning and
other AI research, infosec folks are
investigating ways machine learning can
be used to bring greater speed,
efficiency, and automation to this
process. These automated systems must
cope with devilishly obfuscated
malicious code that’s designed to evade
detection. One key aim is to have AI
systems take on more routine work,
freeing up reverse engineers to focus
on more important tasks.

# ⚓ The_Change_Game:_MeitY_Resorts_To_Quick_Fixes_To_Silence
Experts⠀⇛
On February 21, 2022, the Ministry for Electronics
& Information Technology (MeitY) published the
Draft India Data Accessibility & Use Policy, 2022.
Immediately, civil society experts pointed out
several flaws concerning data privacy and security
rights of citizens. To our shock, on March 6, 2022,
we noticed MeitY had made substantial changes to
the Draft India Data Accessibility & Use Policy,
2022, during the consultation period, without any
public acknowledgement. Effectively this resulted
in multiple versions of it, contracted the
consultation timeline, and confused stakeholders.
Responding to this, IFF wrote to MeitY indicating
the need for a fresh consultation process as these
actions have completely vitiated the ongoing
consultation process and led to an erosion of
public trust.
