I had given a somewhat thorough reading to their API some time ago,
but didn’t find anything that interesting and I was thinking of
developing a java GraalVM API which would be more customizable, easily
usable for other text banks. I took a second look at it and they still
don’t address their own problems, like repeated texts (same exact
text/publication with different identifiers), not standardized
metadata definitions: fr., french, French, fr, … to specify the
language. Author names are entered as free text as well ... so what is
the point of even having an API when the metadata is not well-defined,
-kept.

Well, the Chromium HAR log utility has captured that file as a HAR
formatted one of sorts describing the client-server back and forth and
the Linux file utility is telling me it is: "JSON text data". You may
also go:


https://archive.org/search?query=Euklid+OR+Euclid+OR+Euclides%5B%5D=lending%3A%22is_readable%22


to save that page and tell me what can you start with its content.
This is what I mean with hellishly obfuscated "js cr@p" and I can't
understand why archive.org would do that.

or you could:


a) go: https://en.wikipedia.org/wiki/Karl_Rosenkranz

b) click on: Works by or about Karl Rosenkranz (at Internet Archive)

c) on the archive.org page, select "texts" and "always available"
(meaning text which is public domain)

d) open "More Tools" ... as I explained before (with d.5 I meant you
may have to scroll down or use Key press combinations to "manually"
get all records) in Rosenkranz' case I got 169 texts.

Actually, in order to deX-Y it in case anyone can offer any help, it
is more like "I want an index of all the books which have ever been
written/published" in order to read all of them ;-)


Data registries mind their own extant entries. There is no general,
"orbis unum" registry of all texts (generally meant in a philological,
semiological sense: videos, paintings, ...) just the registry not the
extant data. Terribly persuasive silly me tried to explain this idea
to the archive.org folks and they told me off.

What would that registry be good for? Well, let me use self serving
metaphors, some time ago people didn't know how many people lived in
their countries or even their cities, where did the Nile river start,
what an earth map would look like, ... There was a moment in the
history of humankind in which one person could actually have read all
extant literature (at least relating to one culture, say: "natural
philosophy"). Technically it is not so hard, according to google some
130 million books have been printed since the invention of the
printing press. Not that many, anyway. The idea of reading them all
seized me when I was little after reading a one liner by some Perugian
dude (as cannibalized by me):


"the greatest of all gifts and graces that God has granted us with is
the capacity of overcoming oneself".

 Well, I am old enough to remember when JSON meant: "JavaScript Object
Notation" in the form of human-readable attribute:value text files.

 a) using a chromium-derived browser, which can be used to dump the
HAR file log of the network back and forth, go, e. g.:
  https://en.wikipedia.org/wiki/Anaxagoras
 b) click on the link that says: "Works by or about Anaxagoras" (at
Internet Archive)
 c) on the archive.org page, select "texts" and "always available"
(meaning text which is public domain, he died 25 centuries ago)
 d) then to produce the HAR file, go:
 d.1) More Tools > Developer Tools;
 d.2) click on "Network" tab;
 d.3) Filter: GET
 d.4) check: "Preserve Log"
 d.5) scroll down the page all the way to make the client-server back
and forth cascade
 d.6) save the network log as HAR file to then open and eyeball it!

 1) That HAR file is not properly formatted. Instead of
"attribute":value pairs in the standard way, they have used front
slash + quote pairs (instead of just quotes) erratically all around
the file. That is why you can't use jq.
 2) since they (archive.org) have been changing the format they use on
their pages (to avoid html scrappers?), I don't try to make sense of
what they do. I would just use quick hacks and "keep moving".
 2.a) make editing copy of the file
 2.b) using sed I would parse out the lines with the data I need:
  sed --in-place --expression
's/{\\"index\\":\\"/\n{\\"index\\":\\"/g' ""
 2.c) once you extract them, you then need to parse the fields for
post processing.

 I have tried substring substitution, sed et tr to first replace all
front slash + quote pairs into quotes to then be able to use jq in the
happy way you should. I haven't been successful (is that the reason
why they obfuscate their pages in that way?)

trying to parse lines from an awkwardly formatted HAR file ...

[Albretch Mueller]

out of a HAR file containing lots of obfuscating js cr@p and all kinds of
nonsense I was able to extract line looking like:

var00='{\"index\":\"prod-h-006\",\"fields\":{\"identifier\":\"bub_gb_O2EAMAAJ\",\"title\":\"Die
Wissenschaft vom subjectiven Geist\",\"creator\":[\"Karl Rosenkranz\",
\"Mr. ABC123\"],\"collection\":[\"europeanlibraries\",
\"americana\"],\"year\":1843,\"language\":[\"German\"],\"item_size\":797368506},\"_score\":[50.629513]}'
echo "// __ \$var00: |$var00|"

The final result that I need would look like:

var02='bub_gb_O2EAMAAJ|Die Wissenschaft vom subjectiven Geist|["Karl
Rosenkranz", "Mr. ABC123"]|["europeanlibraries",
"americana"]|1843|["German"]|797368506|[50.629513]'
echo "// __ \$var02: |$var02|"

I have tried substring substitution, sed et tr to no avail.

 I am downloading one by one a bunch of (relatively small) documents I

 Most connections attempts are either missed or dropped even though I
am testing first that the data is there. Maybe you know a better way
you would share?
 When I use brave/private/TOR (which apparently uses its own DNS
strategy) things become a lot less problematic (even if noticeably
slower than it already is), so it seems I may have to run brave
through Selenium ...
 I have never been able to see a traceroute log in all its integrity.
I would not go:
 sudo service networking restart
 after every traceroute run, because I am using my employers Internet
and I don't want to risk "electrons" getting even angrier with me.

[Albretch Mueller]

spend days on end reading, coding and thinking about Math?

As part of turning society/the world as a whole into an "all tangible
things" panopticon they have turned the Internet into a
"freedom-loving" gulag for which they are even using "AI"; so, they
don’t even need to use V-Leute. Those minitrue folks are so smart!

Something that shouldn't be happening at all is that after I use
traceroute once, it doesn't work again and my Internet access speed
describes like a sinus curve which amplitude remains for the most part
under 16KiB per second and for more than one second as 0B per second.

 Right on the Debian Kernel Handbook they tell you you may use
"initramfs hooks" for such things:

 
https://kernel-team.pages.debian.net/kernel-handbook/ch-update-hooks.html#s-initramfs-hooks

 even though I couldn't find exactly the
"/etc/initramfs/post-update.d/" directory used by  update-initramfs
for post update hook options, I notice what seems to be a bunch of
those in:

 /usr/share/initramfs-tools/hooks/

[Albretch Mueller]

I've got a relatively old laptop with an ATI Radeon HD card, which
firmware I can't update. Wild pixelations happen even on relatively
simple pages not just videos. It seems to be a common problem. What I
have searched and found out is that I will have to un/repack initramfs
..., but I haven't found a relatively safe, complete procedure.

How can you update the initramfs on read-only media?

 Well, yes! I think that Debian's APT, dpkg, apt-clone, ... within the
context of how they compare to other packaging systems, their essence
and functions has the potential to become  very beneficial to the
Debian and Linux culture. The other day I heard the author of Qubes OS
himself say that his project was not the be all and end all of Linux
security, that the only way to use a computing device with some of
that thing they used to call "privacy" is not to ever connect it to
the Internet (even physically removing the pertinent hardware and
compiling the kernel without networking libraries if it comes to that)
and I remember Linus Torvalds himself saying once publicly that he
never connects his work horse computer to the Internet. He was even
profusely making faces while he did.

 I think Qubes OS in a sense is an aberration, too wasteful
operatively and I do think that you could run the same box in
air-gapped and exposed mode in the "touch of God" way I already
explained.

 Debian and apt and the way things are done within this OS cultural
ecosystem are fine, except for the assumption of using the Internet as
a trusted medium to any extent ("except", right? ;-)). I just got some
retribution from the Internet AI Gods, it seems. No internet access

 The way I see them, "circular dependencies" are "cultural".
"organizational" issues not essentially technical ones. circular
dependencies happen in packages which should be part of the same node.
Show me examples in which it is not the case.

Debian:12.4/stable [amd64] ...

[Albretch Mueller]

apt-get installation logs (in --dry-run mode) show lines like:
...
Inst libvncclient1 (0.9.14+dfsg-1 Debian:12.4/stable [amd64])
Inst vlc-bin (3.0.20-0+deb12u1 Debian:12.4/stable [amd64])
Inst vlc-plugin-qt (3.0.20-0+deb12u1 Debian:12.4/stable [amd64])
...
you can get most parts of the suffix: "Debian:12.4/stable [amd64]", in
various way except the ".4" and the "stable" parts.

How could you get, list those ".4" and "stable" attributes prior to
running apt-get?

 Well, "my mind" has been partially trained, partially conditioned to
be kind of mix of poetic/artistic, scientific (mostly Math and
Physics, but anything empirical I find fascinating and technical
things somewhat, but I can’t be abused by all that AI cr@p you find
everywhere these days) and downright paranoid and proudly, joyfully so
;-)

 To me saying that you can ensure security, that thing they used to
call "privacy", ... with software would be like saying that you could
invent some sort of esperanto which would not allow for people to lie.

 Package dependencies to me are just DAGs, what I am mostly interested
in is how the various hard-, soft- and "mind"-ware "techne" aspects
related to one another and for that kind of semiotic study you need to
look into the grammar established by the different processes that go
on a computer. The nodes of the DAGs (the "characters" of that
grammar) conditioning the different kinds of transformations offered
by the packages’ utilities when programs run. So, to start I would
like to study the Debian packages and how dpkg establishes and keeps
those dependencies. What happens on the hire and on the repositories
with certificates ... I haven’t found a book yet, explaining it all.
At times I have found great explanations about single aspects.

 ... and mine is of the totally irrevocable, even joyful kind; so,

 I have always believe that Debian’s basic assumptions about using the
Internet as a relatively secure, “private” venue are definitely more
worryingly irrational than my paranoia.

 I think at some point I will have to learn more about Debian’s apt
utility. Any documentation you would suggest explaining it all from
the protocoled structure of deb packages to the various installation
procedures depending on degree of paranoia? When I learn something I
like to learn all of it.

 I tend to only mind what I am working on. I would just use an
unexposed computer and/or do things by hand/on paper if possible, but
you can’t do algorithmic simulations and tests by hand.

 My DELL Inspiron 5593 actually does have a M.2 512GB KIOXIA NVMe SSD,
which I need to use! The problem, as I described here without getting
a solution for it:

// __ I cannot change BIOS settings on my laptop?

 
https://forums.tomshardware.com/threads/i-cannot-change-bios-settings-on-my-laptop.3833102/

 is that I can't access/change the BIOS settings on my own laptop to
make the hdd work in AHCI mode, I think. I have also read that Debian
Linux has problems operating such cards:

https://superuser.com/questions/1502756/debian-not-detecting-nvme-asus-zenbook-ux430ua

I purchased a Dell XPS 8930 with an NVMe dirve. Debian and Fedora did
not recognize the NVMe. I had to use Ubuntu 18.04 for the drive to be
recognized. I'm not sure what Ubuntu is doing that Debian is not, but
I suspect it has something to do with updates. Debian tends to stick
with old and broken software. They will not upgrade for users. – jww

 You may know how to deal with such problems, better than I do, since
I don't tend to mind the intricate technical details about computer
hardware, even though I understand well the physics in them.

 Every piece of computer hardware my paranoia uses seems to have a
mind of its own. I have decided to not use computers (do all the
writing by hand on paper), but the data processing and algorithmic
basis of my paper I have to do on a computer.

 Any suggestions?

 Sorry, but I don't think I am making much sense out those reported errors.
 I may not even have an NVMe card in my computer as the manufacturer claims.

 Thank you I spent some time going over their discussions which in two

 I started my computer with the Bullseye Debian live DVD and the dmesg
log is not flooded with such error messages (as it does with
Bookworm):

dmesg reporting lots of errors apparently emanating from a Realtek RTL810xE PCI Express Fast Ethernet controller ...

[Albretch Mueller]

 I decided to upgrade to Bookworm because I needed to use some NVRAM
memory supposedly available in my computer, but then my wireless
Ethernet started to "complain". I initially thought those errors might
be related to the lazy use of the Ethernet drivers from Bullseye but
when I started to use Bookworm's drivers the errors became more
complicated. Following some hints from:

 Well, the way I see such my options, you could:
 1.1) parametrize a call to a function, or
 1.2) use named files for each type of strace run.
 I would rather use §1.1

 Thank you. As you have suggested to me. I will have to use a

 Based on:

 three questions:

 1) how do you set up the process to be straced as a parameter? Something like:
prx="echo hello"
logfile="file.txt"
#
strace "${prx}" 2>"${logfile}"
ls -l "${logfile}"; wc -l "${logfile}"; cat "${logfile}"

 2) how do you know for sure that you are stracing the same process
that you are running and is logging some data? I had read up from the
links that I included that there are ways to make the shell spit the
process number before a process is run, but how do you then insert the
stracing segment in the one liner in order the use that process id
before the process is actually run?

 The way I understand the PID options of strace:

strace --help ...
 -p PID, --attach=PID: trace process with process id PID, may be repeated
 --tips[=[[id:]ID][,[format:]FORMAT]]: show strace tips, tricks, and
tweaks on exit
 id: non-negative integer or random; default is random
 format: none, compact, full; default is compact

 it seems to be attaching to some already running deamon or server process.

 How do you make it swallow a process that would go in one step/moment?

 3) I have noticed that strace output is not totally predictable, so
"parsing" is not that safe, straightforward

 prx="echo hello"
logfile="file.txt"
#
strace "${prx}" 2>"${logfile}"
ls -l "${logfile}"; wc -l "${logfile}"; cat "${logfile}"


$ strace file strace.wlog.txt 2>&1 | tail -n 5
write(1, "strace.wlog.txt: ASCII text, wit"..., 56strace.wlog.txt:
ASCII text, with very long lines (348)
) = 56
munmap(0x7f127f083000, 8281024) = 0
exit_group(0)   = ?
+++ exited with 0 +++

$ strace wget --help  2>&1 | tail -n 5
Email bug reports, questions, discussions to 
and/or open issues at https://savannah.gnu.org/bugs/?func=additem=wget.
) = 956
exit_group(0)   = ?
+++ exited with 0 +++
$

Notice the diffing "munmap(0x7f127f083000, 8281024) = 0" line
which I think comes from strace.

 But how do you strace a program saving the output (of the stracing)
in a logfile while you also save that program's output without making
it part of the stracing? Say you go:

$ strace -f wget --help

You can clearly see the output of "wget --help" tailgated as part of
the stracing (which, of course, you can parse out), but I want two
separate log files. One for the stracing and the other for the actual
output of that program you ran.

I found some posts suggesting that to be possible, but I couldn't get it right:

 This thread has taken a life of its own and I have learned quite a
bit from our back and forth. This is not how I intuitively thought it
worked. I thought you had to actively ask the OS to update itself ...
Now I am interested in learning all there is to be learned from this
whole time keeping methodology and how it relates to systemd and the
boot process.

 Is there a way to start the Linux kernel of a Debian Live running
instance enabling you to log the whole process (in a more in depth way
than dmesg) and then go "follow tcp" for each listed process in dmesg
as you do with wireshark?

 So, a possible (the only?) solution to those kinds of problems would
be to always and explicitly use UTC, right? Or, using the longitude 20
West (just crossing Iceland, which is 60+ North) or 170 West (too
close to "Vladimir Putin") where so few people live that I don't think
that anyone would care about day time savings or any of that.

 All kinds of software keep time diffs. I am trying to use it in an
obvious human readable way right in the file names.

Hmm! and one hour difference is not detected, because of the way is
being parsed. Why would that happen? Why would %S be in the range
second (00..60), instead of (00..59)?:

seks00=1698539400; TZ=Europe/Berlin date -d '@1698539400' '+%Y%m%d%H%M%S'

seks02=1698543000; TZ=Europe/Berlin date -d '@1698543000' '+%Y%m%d%H%M%S'

diff_seks=$(( seks02 - seks00 ))
echo "// __ \$diff_seks: |$diff_seks|"

 The only way I see is for the running computer on "exposed mode" to
check via systemd if the time zone has been changed and reset it in
that case before you use date for file naming for all data that is
kept in a measured way.

 In the case of the person flying from Paris to Boston he will find
out that he flew away from continental Europe once he reboots his
computer in "exposed mode" (pun intended). He will notified of the
time zone he had used before and all such deltas will be kept. The
only measured data that will be deleted is the one which remains the
same.

 If I understand what you seem to not understand about my work around
to get a time difference in seconds out of my "cobblesome" date
formatting for file names, this is my time zone (remember I am using a
Debian Live DVD, on "exposed mode" ;-))

$ date +%z
+

$ cat  /etc/localtime
TZif2UTCTZif2UTC
UTC0

 At the end of the day, all I need is a time difference in seconds
(and yes, milliseconds would be better), which would be the same
regardless of your time zone.

 I do see the good in what you are suggesting to me and I will have to
include time zones in the file names as well and deal with the
possible cases (someone working at Charles de Gaulle Airport in
Paris/France boards a plane to Boston Logan/MA/USA ...). But the
actual question I will have to deal with is how to check and possibly
reset the time zone and the time via a network in a reliable way once
a ToG booted computer gains access to the Internet for which I will
have to use systemd-timesyncd when it boots and shuts down/ when it
changes modes.

 Am I clearer now?

 What difference would that make when all I need is a time difference?
The way I understand such time format issues is that it needs to just
be the same in the two dates.

 I (erroneously?) thought coreutils was maintaining Linux date, so if
they tell you on their --help instructions to use certain options
(including cobbling them together to your heart's content) and you are
telling them you are using their format and how, they should be able
to parse that string. ANyway, my hack around it wasn't effortful at

 and how does my paranoia relate to that wall of itemized statements

around the sun in exactly 356 days, ... and the adoption of the
Gregorian calendar already caused quite a fuss in the history of
humankind, which, believe me, didn't have to do at all with my
paranoia.

 All my paranoia is talking about is that:
 1) for historical reasons going back to the Sumerian/Babylonian
civilization, the date format we use is not 10-based
 2) coreutils date is not quite true to itself when it comes to en-
and decoding its own formatting options
 3) since time is a scalar magnitude, a time difference will be
constant regardless of my paranoia and the statements on that link you
posted.
 4) contrary to what happens with floating point numbers (which, in
general, you can't represent truthfully as binary), a time difference
in seconds is whole number which you can exactly represent as binary.

 Even people who are not paranoid and know their sh!t would easily see
my points. I would say it is primary school Arithmetic.

Re: difference in seconds between two formatted dates ...

 Well, yes, "date --date= ..." doesn't work in the way I would wish
("logically" think about it):

 
https://www.gnu.org/software/coreutils/manual/html_node/General-date-syntax.html

 parsing any format allowed by date:

 
https://www.gnu.org/software/coreutils/manual/html_node/Date-conversion-specifiers.html

 which made me think of how/why did I start using my "coblesome"
formatting, but there is nothing really that homely about it. Those
formatting options are listed right on:

 date --help

$ date --version 2>&1 | head -n 1

# 63 weeks 5 days 11 hours 0 minutes et 43 seconds later
s02=$(( s00 + 63*7*24*60*60 + 5*24*60*60 + 11*60*60 + 0*60 + 43))

 Actually, my basic idea is if you can encode a date using formatting
options this utility provides, then you should be able to decode it
using the same options that same utility provides, no? ... and then
get "seconds since 1970-01-01" which wouldn't matter when you are
computing the difference between two 10-based whole numbers which can
be represented exactly in binary Arithmetic.

 Thank you. I learned something out of it, but I used such "cobbled-up
pseudo numeric monster" because, in kind of a poor-man's "measured"
way, I use size, line count, last mod and sha256 metadata in file
names baselining the system's state. I avoid spaces and any other
characters you can't use in most fs' and/or may be interpreted by
shells or OSs in their own ways.

 but this is not what I meant and I am sure you can once again impress
everyone here with your bash skills/wisdom. Is there such a thing as:

 dt00=$(date +%Y%m%d%H%M%S)
 printf -(whatever the formatting for seconds would be) "${dt00}%Y%m%d%H%M%S"

 I dealing with my "exposed mode" kinds of states ;-). I use a
computer which initial state is kept as part of the file name as I
explained, then as part of another ("exposed" or "private") reboot I
want to check that file, so I would not be able to then simply do $((
dt02 - dt00 ))

 After rebooting (separately for "exposed" or "private" mode):
 a) those kinds of name measured files are checked,
 b) if everything is fine you would keep some basic statistics (last
difference; as well as, incrementally, average, stddev, skewness and
kurtosis of differences so far)
 c) delete the file(s) previous to the latest one
 ...

 and, no, I am not expecting for bash to do that kind of statistics
for me, but I would love to see once again how wrong I am.

 No calendar issue here. All is needed is turning dates into seconds

you get seconds in dt00 and dt02 and then the difference. You can't

 My mistake, even though it didn't get in the way of what I was trying

 I like your second one liner much better (LC_COLLATE=C tr -c -s 'A-Za-z0-9.' _)

 I tend to avoid '[:alnum:].' because the intended meaning of

 Ach, yes! I forgot echo by default appends a new line character at

echo "// __ \$_FL_TYPE: |${_FL_TYPE}|"

Re: why would "tr --complement --squeeze-repeats ..." append the substitution char once more? ...

[Albretch Mueller]

 "tr --complement --squeeze-repeats ..." makes sure that the replaced
characters only appear once (that it doesn't immediately repeat). Say
you have something like "  " (two spaces) or "?$|" (three characters)
which will be replaced by just an underscore.

In the case of: "ASCII text"
 what should come out of it is: "ASCII_text"
 not: "ASCII_text_"
 no underscore at the end. That is the question I have.

 I use such constructs as: "[A-Za-z0-9.]" to make explicit to myself
and other people what I mean. I work in corpora research dealing with
text based various alphabets not just in ASCII so I avoid any kinds of
linguistic/cultural shortcuts and abbreviations.

Probably echo and tr are not dancing well together. echo might be
tailgating an end of string character which tr then replaces with an
underscore.
which option do I use with echo for that not to happen?

 which (cell phones) they would also get "for free", mind you.

 And well ..., yes, even if you remove the networking hard and
software, all RF devices need are electrons moving around in ways you
can control and encode. Some time ago, I heard the expected news that
they had managed to sandwich a RF circuitry on the layers of a chip!
So, expect for everybody to start making their own chips at least for
their most critical infrastructure!

 There will however always be physical ways to hack a hack. Imagine a
bugged cell phone, you could always physically extend the
functionality you need and keep the cell phone itself encased in a
Faraday cage at all times.

 Thank you. I should have more clearly stated that those computing
devices would go each about their particular business situationally in
an air-gapped mode to then each go about their "collective
intelligence" on a separate computer, a "server" of sorts.

 These days, everything from microwave ovens to pacemakers are
computing devices, but why should they be wifi-enabled? People don't
seem to even realize that since the 1990's they have been driving
computers on wheels. Then you hear that Vladimir Putin assassinated
Michael Hastings for saying the same Joe Biden said only two decades
before; you hear targeted individuals talking about of smoke rings
(something that can't happen in nature by itself) to then hear about
COVID-19 and how it was all started in China by some dissident
"freedom-loving" bats, ... I even heard once as part of those marginal
comments you hear which make you go like, say what?, that courtesy of
U.S. tax payers the CIA was giving money to Ukrainian people but in
order to get it they had to use their cell phones ;-)

 Think monitoring devices in hospitals, schools, power plants, ... I
once heard that some "intelligence department" knew the grounding
truth about some matter which happened in some remote place in Russia,
because they had been monitoring the cell phones of not only "we the
people", but even the police and, of course, when you hear such thing,
since neither Physics nor "God" have "blue-eyed sons" (contrary to
what some Israelis/Jewish people may think) or as they say "what is
good for the goose is good for the gander", that also means that "the
Chinese", "Russians", ... are able to do the same thing (of course, in
their case they do it "because they hate freedom"). Now, imagine that
at least the police would use a "ToG network" (to call it something)
without any networking capabilities on a hard- and software level
(just the necessary functionality, for example, passively getting GPS
coordinates for which you don't need the whole networking stack) for
their computing devices with a One-Time pad lease for the session they
will be using it (and they would be physically powered for the amount
of time they need to be used) which they must relinquish after each
day of work to their base and which data would be encrypted (reusing
the initial OTP) in ways that only the server which leased the OTP
would be able to decrypt. Think of how they hacked the enigma machine
and how Nazis suspected such a thing to have happened:

 https://en.wikipedia.org/wiki/Erhard_Maertens

 What could those "freedom hating" Chinese, "what the heck is freedom"
Russians, all those "intelligence departments", ... do about any of
it?

 I explained the basic idea to a friend over the phone and clarified
to him a number of doubts he had about it. He got it. He also realized
that it wasn't much of a hassle, really. And he told me that I come up
with such ideas because I have been forced to look at reality from a
different point of view. In a Hegelian, karmic way it is a good thing
that people looking at reality from different vantage points can talk
to one another, even though, as they say, "misunderstanding is as
mutual as love should be".  No XY problem whatsoever, and I am not
trying to hide anything from anyone (whatever "hiding", "privacy", ...
could possibly mean these days). As Mike Rogers (of Pink Floyd fame)
said when he was being accused of being a racist, anti-zionist or a

 I could even envision industries around such specifications. The only
reason why such things haven’t happened (would not ever happen?) is
because police, politicians and IT companies (which these days are all
the same) want to run society as if we were all rats in a maze they
control real time in a predictive and cross correlating way in which
everything is ephemeral to "we the people" while they keep a click by
click, keystroke by keystroke, breath by breath, ...  data
Doppelgänger of each of us.

 Something "my paranoia" noticed as part of the Snowden revelations
which IMO hasn’t been aired, questioned, discussed enough was that the
NSA, as part of their "all tangible things" doctrine, was most
interested in people’s medical records. Why?!? Why would "they" care
about people’s health? Isn’t the safety and betterment of society what
they should be interested in? To top it all "we the people" didn’t get
the extent to which they were making fun of us when they said that:
"what matters is how we use that information, not that we collect
it"!!!

 This is how the world we are living in looks like:

 I am not into protagonism and that is not my main line of research,

 I beg to differ and at the end of the day this is something that can
be physically/technically proved. Basically, how could you hack a
computer which you booted without a physical networking interface and
(part of the objectives) without loading the networking capabilities
from the kernel by exploiting Linux' runlevels? All you would need to
do is automating updates to that configuration.

> - Maintaining such systems is a pain.

 Well, not really! Booting a Debian Live DVD doesn't take more time
than booting Windows (from scratch) and the whole idea of using a
package extensions USB pen drive would automate updates. This
basically is all there is to maintaining it. You would be basically
making use of the BIOS and RAM of a computer (you don't even need to
own), you would keep the whole OS and all extras you need in your
shirt's front pocket. If they mess with the BIOS you will notice it
because the thing will not work and it would report the BIOS change
and exactly how, what the difference is and for basic physical reasons
you can't infect a computer's RAM.

> - There are no shortcuts.

 Well, no! ... and this is a good thing! We both, "hackers" and "we
the people", have to follow step by step procedures (what Ancient
Greek thinkers called "techne" and later we meant by "functions" up to
Descartes, before all that non-sensical "black box", I/O mindset took
over), what makes the difference is "the touch of God" and that no one
can take away from you that you could take care of your own security,
privacy (as existential philosophers would say: "absolutely no one,
nothing can take away your freedom").

 Notice that I am not just talking about computer soft and hardware. I
got my education as a theoretical Physicist (basically a double-major
in Physics and Math) an der TU Dresden, so I tend to see, understand
every through its physics.

 Experiment:
 1) use a hermetic metal (not plastic, looking like metal!) box (one
of those they use for candies)
 2) turn on your cell phone and carefully put it inside (making sure
it stays on)
 3) close the metal box
 4) right in front of that box place a call to your own phone using another one.

 Well, yes! and how would those kinds of anecdotes speak against a

 As anyone could see you could even run a network of detached
computers without networking interfaces in a "touch of God" kind of
way, some sort of "leased One-time pad touches of God" specifically
for each, all coordinated through and which data/information would end
up in a kind of "server", you could even use cell phones to do such

 We all know that a DVD caddy could be easily bugged as well (the USPS
keeps stocks of all kinds of equally looking things which are bugged)
and  a DVD caddy is more of a mechanical, more power consuming thing,
so it would be ideal to go the knoppix-like "toram" way. Knoppix these
days is based a debian, so figuring out the grub hack to pass start up
arguments to the kernel at boot time shouldn't be difficult. You would
also be freeing the DVD port in case you need it.

 "bootfrom" would be also nice (I think in knoppix you can even
combine the "bootfrom=<...>.iso" and "toram" start up options!). These
days it doesn't matter much because you could use WSL (Windows
Subsystem for Linux), but for whatever reason you may want to just use

> ... that thing they used to call "privacy".

 I am old enough to remember the times in which telling someone that:
"you care about their privacy" would have been taken as an odd joke.
It would tacitly mean that -you have no privacy whatsoever-! Privacy
is one of those things you would have to take care of yourself! (ToG-L
would enable "we the people" to do so) In some European countries not
just the government has implanted chips in military personnel, but
your boss would make it a precondition to be hired even though it
doesn't relate to your job description in the least! "We the people"
would get chipped just to be part of a dance club! Some government
have had ideas about chipping everyone which makes you wonder if
people have started to lose their senses "in the end of times" ...

 Einstein who made his main occupation the mathematically measurable
aspect of the it, mind you, said: "two things are infinite: the
universe and human stupidity; and I'm not sure about the universe".

 I am not trying to be persuasive anyone. I actually think in the
times we are living things have gotten more than half way off for way
too long and we, scientists, tech monkeys and Mathematicians could and
should inform "we the people" and help them more actively have their
stand on, way out of such issues.

 that didn't work, dpkg would still demand dependencies, so I decided
to change the strategy to:
 1) using apt-get install ...
 2) save the install log into a file (apt-get install reports to you

 Hmm! ... and the apt-zip functionality doesn't exist anymore in the

ToG Linux (first draft of a RFC) ...

[Albretch Mueller]

ToG Linux ("Touch of God" (no blasphemy intended) a la Michelangelo's
"The Creation of Adam", with one of the poetic connotations being, to
make best use of what you know to be certain, what "you can touch"
(can exclusively reach with certainty), is readily available in your
immediacy (before the physical reality of fields was understood,
Leibniz made fun of Newton's "actions at a distance", of which Newton
himself admitted not to know its origin and nature ...))
This would be a first draft about what could be considered a poor-man
Debian Live air-gap running instance. I post it here because Debian is
definitely my favorite distro (and many other are based on it), the
deb live and blends mailing lists are mostly about specific changes to
their project and I am talking about general topics relating to
securing a Debian Linux running instance in a relatively straight
forward way based on options which are already available. No fanciness
or "conceptual demands"! Nothing new under the sun! It is more of a
„Deutsches Eck” kind of thing, making things confluent to make good of
them.
Some of the ideas have nothing to do with Debian per se, but
objectives which conceptual ecosystem aims at being able to use
computers with some of that thing they used to call "privacy", at the
very least less exposure. Most of the measures are procedural and
physical (involving hardware). Using just software would just be an
illusive waste of time.

0.1) even though by their very nature OSs', applications, network-

software which manage to get in your system would be mindlessly erased

away, they need persistence and they know they would be exposing their
rear end to the four winds and that you won't have to spend your mind
on worries and/or your hard earned money on "virus scanners", "malware
detectors", ...);
0.2) you may be able to and should use the same computer in both:
exposed, and "air-gapped" mode;
0.3) ToG would require just some disciplined and prudent exercise of
your exposed activities, (if any) near to zero comma nada monetary
investment;
0.4) ToG would let its user base have -some- healthy and aware
tranquility of mind when it comes to safety and "privacy";
0.5) the use of a package extensions phase during the boot process,
makes blends unnecessary, since you would enhance the functionality of
your initial Debian Live DVD during boot up in whichever way you want
and even use other supported architecture*.

USB pen drive can be a RF device in ways you can't simply tell apart
from regular ones) and most (all?) breaks into air-gap systems have
been through misuse of USB pen drives)*
1.2) a "package extensions" USB pen drive (where you would keep extra,
specific packages you need, not included in §1.1) and a lokal web
references file;
1.3) a computer, you own*, which:
1.3.1) BIOS doesn't include networking, is open source (could be
"trusted and checked") and which binaries you can linearize and dump
in full as a file*;
1.3.2) BIOS lets you choose the boot device;

 At times *being* and *keeping moving* is entirely fine, you don't
have to be *happy* and I am not sure if I am living in the stone-age
or the brave new world in which we are living these days. One thing is
sure, I can't be naive about any of it.

 I do have the "same-release, same-architecture connected system" I
just want to make as sure (among other things meaning -on a hardware
level-), as I possibly could that, by simply rebooting a live DVD you
can "switch" (as it were) from one to the other.

 As a simple matter of economy (I use almost exclusively amd64 based
hardware), I am trying to streamline a way of:
 a) booting a live Deb Linux from a DVD (which, physically, you can't
write onto)
 b) running a short script with an array of utility packages which are
not part of §a's install base preferably from a pen drive or a
subdirectory of a hard drive you could mount
 then you would:
 1) boot up
 2) (from the USB pen drive) run §b's dpkg-based script
 3) install the extra stuff you need including Selenium-automation
versions of firefox (gecko) and brave (chromium)

I have no other way to work. They are even using "AI" to mess with

 I am using apt-rdepends --follow=Depends 

 to download all dependencies into a subdirectory for each package
then I notice the same files: srcpkgcache.bin et pkgcache.bin in every
subdirectory.

 Once we go into exposed mode (go online), we tacitly become all

 Yes, of course, you can always do so. I meant it would be best if
certain security issues are dealt on a hardware level. It may sound as
"paranoid", "crazy" to you, but I always go into exposed mode using a
Debian Live DVD, basically:

 1) boot up
 2) mount local drive (reset my home dir ...)
 3) mount USB pen with extra stuff I need
 4) customize my run by using dpkg to install packages from the USB pen drive
 5) unmount, remove pen drive
 6) physically plug in Internet enabling hardware
 7) install the drivers to be able to connect to the Internet ...
...
 (n-2)) disconnect yourself from the internet (software + hardware by
removing the wifi USB dongle or cable) ...
 (n-1)) run script to check which files were changed during your run and how
 n) shutdown

 Yes, it is cumbersome, but it is the only way I can access the
Internet with some reliability.

 It is not just about soft- and hardware level measures, "hackers" as
part of their modus operandi need "persistence". They would not spend
their while and expertise knowing well that by shutting down your
computer you would be effortlessly erasing all their cr@p, along with
all cookies and all of that and they are smart enough to realize that
they would risk exposing their rear end to the four winds. If they
continue doing such thing you will know the kinds of "legally
protected" hackers that would not mind such risk.

 I have to use a Debian Live DVD to access the Internet; so, probably
these utilities should be included. I can't entertain functional
illusions about taking care of my business in any other way. It is
thoroughly annoying and time wasting, but you also "live and learn". I
have been running dmesg and comparing its output as I access the
Internet (all problems go away when you close all browser windows and
disconnect yourself from the Internet) one of their jokes is making
the hard drive crazily rev and then you find the message:

addition to running diffing the output of dmesg.

 The main problems I am having are brought about by:

 1) the BIOS of the laptop I use these days having wireless networking
which is started by the BIOS (at some point I will try dealing with
that by disconnecting the built-in hardware). In the ways I understand
"reality" (and "quid est verum?", right?) the BIOS should not be
taking care of networking, "have a mind of its own";

 2) javascript is the main attacking framework used by "the
government" and how can you use the Internet these days with
javascript disabled? (it would be like trying to breathe underwater)

 3) "the government" is using AI for their societally-wide
Zersetzung-like "social control" (as "good Christian" "freedom lovers"
call -repression-)

 How do I know, am so sure about it? Well, this is a pattern that I

in a "lexical priming" kind of way, if you elaborate on your
statements even if in a jestful way, "patriots"/their "'patriotic'

 This is what happened last/this time: you notice the people you get
the news from (I don't watch TV, read newspapers, nor am I on social

 Well, actually, yes. This is how I have been mounting the Windows
NTFS of my laptop and my employer's as well without any problems
whatsoever. I just open the file browser/viewer and click the drive to
mount it in order to unmount, eject it you right click on it. It
works.

 Apparently, some of us do. ;-) My obfuscation of the path didn't
relate to the error.

message about the drive. If so, let Windows 'fix' it. I've had cases
where the drive was not cleanly unmounted and Linux has mounted it
read-only. Windows was able to repair it, whatever the problem was.

 THis is the second thing I did. I booted into the BIOS and run an
exhaustive test/diagnostic on every physical part of it twice. It all
tested fine, including the hard drive.

 Then something spooky happened. I couldn't care less about Windows,
but then "'the BIOS' 'told me'" it would fix my laptop and it effing
did without messing with any of my data!!! Then I could boot into
windows again ... once I checked everything was fine I went back to my
Debian live ways.

 Every electronic thing I use has a mind of its own, that makes your
life so much more enjoyable! ;-)

> Did you disable the Fast Boot feature in Windows?

 Yes, I did. I had to reset the BIOS to "factory settings" which also
changed the clock time which then I couldn't change with hwclock ...
but when I booted the laptop with a network access at the library. It
did reset the clock apparently using WIndows time servers.

 That fix took me like four hours (dealing with the nonsense of the
installation ...), but at the end of th eday I was able to go back to
my do, do, do, ... mode.

when I try to save or download a file I consistently get the same error message:

$ cp "No space left on device" > No_space_left_on_device.txt
bash: No_space_left_on_device.txt: No space left on device

that started happening right after a WiFi connection at a library was
shutdown, which I waited for with my script running, accessing the
Internet, because I wanted to test such a case. Script "gracefully"
worked as programmed to do, but that other error started right after
the connection was cut off.

I have no idea how could those two things be related! Why would that
happen? Any suggestions, please?

 I do that because base64 would (must?) work on any OS and the
conversion from and to any other encoding is straightforward. As you
suggested, I am more friendly to the idea of including hashes of the
data payload, even though I think it is not that important, because
the actual big problem that corpora research people have is files with
exactly the same look and feel and the same content which have
different hashes (for example, pdf files). I have been thinking about
a way to compute hashes which resemble more faithfully, both,
structural and content similarity among files. Do you know of any way
to do such thing? The structural aspect should be "easy". It could be
handled as DAGs of some sort of XPaths.

 Even if not totally syntactic (so you can't functionally solve it
with some code), this is a relatively manageable problem, you would:

 a) take notice of the sites that do such things;
 b) sniff not only the http headers, but notice the file extension of
the file; and
 c) safe the file to a temp repository for the Linux util "file" to be
run on it ...

 Out of those heuristics you should be able to strategize around such problems.

 What do you mean by "hashing the document content"?

 OK, now I see why cutting off the string on the first space that
appears is safe. I never saw such cases because I always used sha*sums
on files. I would expect if a user enters a string via printf that was
all there was to it. Of course, sha*sums can tell apart a file from a
text string.

"Miller, Henry", "Miller, Henry 12-1891 06-1980" apparently as
different authors/"creators", to the gutenberb.org large text bank
including some protagonistic bs in the actual texts, to developers of
libreoffice watermarking text with some cr@p which of course is being

once an epiphany while watching Trump talk to a media prestitude who
caracteristically wasn't making much sense. After asking a few
questions trying to make sense of what she was saying, prestitude said
"let me formulate it better". Trump quietly sat back saying: "OK, take
your time"!!!

 I was amazed! There you have someone the U.S. media, who as a mouth
piece of the status quo, were being viscerally offensive towards
anything relating to him, including posting on the front page of
mainstream US news papers naked pictures of his wife and mother of his
child one month before she became "the first lady" and he took it
easy, respectfully on her! That was the best case I have noticed so
far of "separating the message from the messenger". I mean people who
erect all those pay walls and somehow see themselves as authoring,
guarding content are not even the messengers and we all have to put up

 Yes, you could but I am trying to find out why this is happening

 yes, I know and my way to deal with such issues is:

 a) by including in the name of the web log of the download the date
and time ...
 b) once the data file is downloaded, say a pdf file of an old book or
some publication, all the metadata in the front and back pages of the
book are OCRed, the actual title, ISBN, publishing date ...

 because I would like to include the three strings in the file descriptor:
 a) the crazy long name
 b) its base64 representation
 c) §b's sha256sum representation which is the one used for the file
name and the log of the download.

 I would like to make this scheme "fool (and fail) proof" as they say.
There is no way in earth that a file system messes with all three

 The local copies should represent the web URLs as close as possible
in order to minimize "what came from where" kinds of confusions. Also
from the same URL you would then download the corresponding pdf file
with exactly the same name, the only difference being the extension.

 Thank you. I was playing with different options to see if that was
the reason I was getting those white spaces and hyphens at the end.

 Why is that happening? How could it be avoided? COuld you set the
characters used in the representation of a sum?

sha256sum --text generating blank spaces and hyphens?

[Albretch Mueller]

 This is not a debian question per se (more like a Linux bash one),
but I wasn't able to find an answer on the Internet.

 Here is first the problem I am having before you start reading a
conspiracy theory into it ;-)

 I need to somehow map URL on the web to a local file, but you can't
do that for two main reasons:

 1) URLs are free text
 2) which people take to their heart's content.

 Take for example:

 
https://dokumen.pub/qdownload/nietzsche-und-der-deutsche-geist-band-4-ausbreitung-und-wirkung-des-nietzscheschen-werkes-im-deutschen-sprachraum-bis-zum-ende-des-zweiten-weltkrieges-ein-schrifttumsverzeichnis-der-jahre-1867-1945-ergnzungen-berichtigungen-und-gesamtverzeichnisse-zu-den-bnden-i-iii-9783110202861-9783110189865-3110189860.html

 that file and the pdf you would download I need to map to a local
directory looking like: ... /pub/dokumen/qdownload/ ...

 but the file name (excluding the extension) is 306 characters long,
which Windows NTFS would not swallow. There may be also funky rules
regarding character sets and where in a string certain chars may be
used; so, as a way to work around those kinds of problems I:

 a) encode the string name as base64
 b) calculate the sha256sum of §a
 c) use §b as file name (of course, leaving the original extension as it is)
 d) include a "§b_file_name.txt" plain text file decriptor which only
content is the actual prehash name of that file.

 I am trying to avoid funky characters and sha256sum --text still
generates them!?!

 I work like this because I need replicate the original URL as a local
path in a way that would be compatible any file system.

 Do you know of a better way to deal with such issues?

 Once again, "social" issues remind me of my dear grandpa Hegel ;-).
There must be idiotic people like me for "smart" people out there to
"be themselves".

 The issue at hand was the traceroute exaggerated "* * *" output, no?
BTW, I made sure to put a "'little' tin hat" on my post and phrased it
knowing well "it would be archived", but, in case you want to believe
me, those actions weren't directed at you.

 Here are my candidate elucidations (and from the little corner from
which I see reality Occam's Razor doesn't really apply); either the
"international community" (tm) doesn't like that niggah me has to
download vast amounts of data items (it is almost exclusively text
anyway, so I don't know what the big deal is and I have noticed people
on the same network (using windows terminals) with more than one
browser window open watching high def videos) so, it might be my usage
patterns which is flagged as "dangerous" dude misbehaving.

 There is also some idiotic perp invariably dressed on a pink shirt
that USG is paying to occupy a relatively retired seat where I used to
sit my days. Unfortunately, I couldn't take a picture of him for you
to "analyze it" ...

there.

 Yes, but should it happen on every hop? In my case it happens while I
am trying to reach every site and from wherever I have the chance to
get some relatively decent Internet access?

 A descriptive metaphor would be. You can see the traffic light once
you get out of your home's drive way, but the rest of all of them
misfunction regardless of where you are driving and the time of the
day and it always, consistently and apparently, exclusively happens to
-you- ;-)

SQUASHFS error: Unable to read fragment cache entry ...

[Albretch Mueller]

 I always use a Debian live DVD while exposed.
 The thing is that in order to squeeze every minute of attention I
possibly can I tend to:
 a) just close the lid of my laptop
 b) while keeping the DVD player attached to the laptop
 c) then, reopen it and continue.
 That way I avoid like 5 minutes of configuration time.
 Not always, but most of the times I start getting those kinds of errors.
 Basically, I need to be able to close my laptop and pack it up while
I am going from point A to B and then take it out and continue.
 How do you guys to that? I mean, "you guys who must use live DVD" ;-)
 Any helpful tip would be appreciated!

What do all those "* * *" mean on a traceroute log?

[Albretch Mueller]

 I have found a few examples and "explanations" but in the cases of
the examples I have seen by other people, like:

 
https://serverfault.com/questions/733005/what-does-having-mean-in-the-command-traceroute-and-how-can-you-cope-wit

 It is not with every site and it is mostly with one hop. I my case it
is with all sites and once the packets reach the web (from hop 5 to
30), from wherever I connect to the Internet. Why would that happen
and why would that -consistently- "happen" to me?

 Well, debian folks say it is gradle folks the ones that didn't get it
right and vice versa.
 As you could see from their installation page, the one and only
installation prerequisite is a java version after the reflection API
was introduced. I would guess everyone who works from a Debian install
and need to install gradle is because they are using java already.
There have been 7 releases till JDK 19.

 Maybe debian packages should have various installation candidates
based on the JDK one has installed or during configuration of the
package if no java install is reachable it should look for it in the
filesystem and if it is still not found tell user and abort the
installation.

Re: gradle wants openjdk-11 even if a newer version is installed? ...

[Albretch Mueller]

 OK this is what the gradle folks told me/us:

 
https://discuss.gradle.org/t/gradle-wants-as-java-version-openjdk-11-even-if-a-newer-version-is-installed/45254/6

 Gradle itself would just use the Java from your JAVA_HOME or as
fallback from PATH (given you use a version that is compatible with
your Gradle version, otherwise it will most likely fail to execute
later on).
~
 so, the installation by apt-get should have detected that I had set
JAVA_HOME and the included the JDK in my PATH.

 In case someone stumbles on the same problems, runs into the same
thread, here are the quick steps about how to install gradle on Linux
(without gregorian chanting " ... and if you use Windows, ... and if
you use MacOS, ..."):

 1) look for the installation file at: https://gradle.org/install/

 right now:
$ date
Tue 28 Mar 2023 06:14:52 PM UTC

 it was: https://services.gradle.org/distributions/gradle-8.0.2-all.zip

 2) set the directory where you want to keep the installation file

 3) download the file to §2 using wget, curl or your browser

 4) choose an 

 5) unzip -d "§4: which ever  you chose" "§2:
path to the installation file "

 6) set your: PATH="/bin"$PATH

 7) test everything is OK:

$ which gradle
/bin/gradle

$ gradle --version

ERROR: JAVA_HOME is not set and no 'java' command could be found in your PATH.
