Natrium Tri-carbonaat {NL}

I am fortunate enough to have had the best teachers of my school era, still available when I was going to school; you know; that place where they teach you to

be quiet
not ask too many questions
sit quietly and still for hours
do as you're told
basically program you to become a working drone

That part didn't work on me.

All others good things did work

I learned

the languages
the Physics
the Chemistry 🧪
the Mathematics
Linear Algebra
the Quantum Physica
on every process I was already executing ever since I was a young bright child

6CO2+ 6H2O = C6H12O6 + 6O2

This is one of the most important chemical formulas / chemical reactions on Terra

If you've never had any chemistry please go and look it up {sources}.

It's important to know this formula by heart.

If you've had chemistry in school, didn't really like the subject, please also go look it up too.

When you've read the article about this reaction you will understand why I made that statement of massive importance.

Without this Natural Chemical Reaction, life, complex life 🧬 for the species of Homo Sapiens would not be possible!

There are many other reactions in chemistry which dictate what we do, which drive our Corpus, which drive our psyche. I shall not delve into those now, that is for other articles.

With all this knowledge in background, I saw this generic article on chemistry and this molecule jumped out

Na2CO3

Natrium Tri-carbonaat {NL}

The carbonates are very important and very interesting chemicals which many occur in nature. In fact, the things that they can do for us are so vast and diverse, that I will just point you to a page where everything is neatly and properly explained, on a technical dedactive level.

Alkaline reactions are a few of the processes that the carbonates can do for us.

Carbonates are used to soften water

Ca2+ + CO2−3→ CaCO3 (s) {sources}

We also use it in cooking, you do that too, when we bake with dough

When you've read just a section of the article, you'll realize that you use this family of chemicals everyday ;)

Chemistry 🧪 has never been a mystery for me. I love the way many processes work chemically, it makes everything in nature so nice and beautiful.

A cohesive comprehension of Nature builds within you, when you understand the mathematics, the physics, the chemistry of processes, which in the beginning seem complex, but are quite simple when divided in the sub processes

Я дал AI-агенту канбан-борд, и он справился с проджект-менеджментом лучше моей команды

Есть такой момент, знакомый каждому, кто долго работает в паре с AI. Сидишь в терминале, Claude генерит код, ты ревьюишь, правишь курс, снова запускаешь. Проходит пара часов, и ты понимаешь: никто не записал, что вообще произошло. Ни один тикет не обновлен. Таймер не запущен. Чат на тысячу строк, но он испарится, как только закроешь сессию. А когда коллега спросит, что было сделано за день, ты будешь восстанавливать картину по памяти. Удачи. Меня это достало. Заканчиваю марафон-сессию с Claude или Codex, ощущение, что гора работы сделана, а доска проекта все так же показывает Not Started. Тайм-трекинг? Какой тайм-трекинг. Разрыв между реальной работой и тем, как выглядит проект, стал просто нелепым.

curl

Daniël Stenberg

facts and praise

I'm fortunate that I am allowed to follow Daniël, lead programmer of the mightycurl. The reason I formulated the line in this way, is because only through the power of the FediVerse I've gotten a boost from someone I follow, who found a post of the lead programmer or curl interesting

stats:

install base => 20000*106 devices

20 billion+ installations!

curl is used in command lines or scripts to transfer data. curl is also libcurl, used in:

cars
television sets
routers
printers
audio equipment
mobile phones
tablets
medical devices
settop boxes
computer games
media players

Curl is THE Internet transfer engine for countless software applications in over twenty billion installations!

curl is used daily by virtually every Internet-using human on the globe!

curl is 30 years old

Let that sink in!

Opinion

curl is mature critical network infrastructure software that we all need to have our internet powered software / hardware to function in respect to data transfer.

The syntax to use curl in simple implementations is IMHO quite easy. In case you need to know an extra option, the executable and libcurl have excellent documentation. End users normally interact with curl using the (elf) binary on Linux based POSIX operating systems. The more mature BSDs have another binary format

Just type curl to get an initial output which looks like this on my current system

curl
curl: try 'curl --help' or 'curl --manual' for more information

then type

curl --help
Usage: curl [options...] <url>
 -d, --data <data>           HTTP POST data
 -f, --fail                  Fail fast with no output on HTTP errors
 -h, --help <subject>        Get help for commands
 -o, --output <file>         Write to file instead of stdout
 -O, --remote-name           Write output to file named as remote file
 -i, --show-headers          Show response headers in output
 -s, --silent                Silent mode
 -T, --upload-file <file>    Transfer local FILE to destination
 -u, --user <user:password>  Server user and password
 -A, --user-agent <name>     Send User-Agent <name> to server
 -v, --verbose               Make the operation more talkative
 -V, --version               Show version number and quit

This is not the full help; this menu is split into categories.
Use "--help category" to get an overview of all categories, which are:
auth, connection, curl, deprecated, dns, file, ftp, global, http, imap, ldap, output, pop3, post, proxy, 
scp, sftp, smtp, ssh, telnet, tftp, timeout, tls, upload, verbose.
Use "--help all" to list all options
Use "--help [option]" to view documentation for a given option

When you type curl --manual|less you get the manpages which I delimited with less through a vertical pipe

NAME

    curl - transfer a URL

SYNOPSIS

    curl [options / URLs]

DESCRIPTION

    curl is a tool  for transferring data  from or to a  server using URLs.  It
    supports these protocols:  DICT, FILE,  FTP, FTPS,  GOPHER, GOPHERS,  HTTP,
    HTTPS, IMAP,  IMAPS, LDAP,  LDAPS, MQTT,  POP3, POP3S,  RTMP, RTMPS,  RTSP,
    SCP, SFTP, SMB, SMBS, SMTP, SMTPS, TELNET, TFTP, WS and WSS.

    curl  is  powered  by  libcurl  for  all  transfer-related  features.   See
    libcurl(3) for details.

URL

    The URL syntax is  protocol-dependent. You find  a detailed description  in
    RFC 3986.

I can also type man curl to get a nice output:

curl(1)                                         curl Manual                                        curl(1)

NAME
       curl - transfer a URL

SYNOPSIS
       curl [options / URLs]

DESCRIPTION
       curl  is  a tool for transferring data from or to a server using URLs. It supports these protocols:
       DICT, FILE, FTP, FTPS, GOPHER, GOPHERS, HTTP, HTTPS, IMAP, IMAPS, LDAP, LDAPS, MQTT,  POP3,  POP3S,
       RTMP, RTMPS, RTSP, SCP, SFTP, SMB, SMBS, SMTP, SMTPS, TELNET, TFTP, WS and WSS.

       curl is powered by libcurl for all transfer-related features. See libcurl(3) for details.

URL
       The URL syntax is protocol-dependent. You find a detailed description in RFC 3986.

       If  you provide a URL without a leading protocol:// scheme, curl guesses what protocol you want. It
       then defaults to HTTP but assumes others based on often-used hostname prefixes.  For  example,  for
       hostnames starting with "ftp."  curl assumes you want FTP.

       You  can specify any amount of URLs on the command line. They are fetched in a sequential manner in
       the specified order unless you use -Z, --parallel. You can specify command line  options  and  URLs
 Manual page curl(1) line 1 (press h for help or q to quit)

The reasoning behind curl --manual is simple. On a machine without the manual system you still need access to the full manual. This is one of the reasons why man curl is also implemented as curl --manual

An important RFC is echoed to my terminal in the man curl output which is RFC 3986

A Uniform Resource Identifier (URI) is a compact sequence of
characters that identifies an abstract or physical resource. This
specification defines the generic URI syntax and a process for
resolving URI references that might be in relative form, along with
guidelines and security considerations for the use of URIs on the
Internet. The URI syntax defines a grammar that is a superset of all
valid URIs, allowing an implementation to parse the common components
of a URI reference without knowing the scheme-specific requirements
of every possible identifier. This specification does not define a
generative grammar for URIs; that task is performed by the individual
specifications of each URI scheme.

I shall not quote the whole RFC 3986 here. You can read all about it on the RFC site (see sources)

As you can see curl is thorougly documented, has all the features a simple end user needs to fetch all kind of data, scaled up all the way to the extensive complex features router hardware et all, needs to transfer data.

programming route

I came to this toot when I saw that certain external feature code, which lives in stable external libraries, is now being removed from curl. I should say the code is depreciated then phased out.

This is a logical step

It takes resources to maintain external code
If the (shared) libraries are stable and mature, it's much better to just call those libraries and be done.
The more external code you can remove from your project the better it is for all the programmers

The same is also happening in the Linux kernel, they are following in the footsteps of curl

Conclusion

There is a treasure trove of information in the sources. Just reading the pages on RFC 3986 will keep you occupied for hours.
Have fun and keep reading / learning and programming!

C64 SID

The SID CMOS IC in the C64 delivers an interesting eight bit sound colour in the C64

When I first heard the C64 SID as a kid it was nothing to throw your hat at. I've had experiences with concert piano's, tenor saxophones, percussion instruments in the electric range professional synths, bass guitars so I knew this bleep bloop ssshtt IC could never sound the way of the pro musical hardware, especially not the acoustic instruments.

Last Ninja I

It was when I heard the music of Last Ninja I knew that with it's severe limits, the Sound Interface Device has something special to offer. The composer of the music of this game did something marvelous.

He used arpeggio techniques to make the SID play chords

SID does not play polyphonic sound
Arpeggio gives the illusion of chords due to the rapid succession of notes played
Iconic music was spawned with Last Ninja
Unique arpeggio chords created on the SID are still seeked by those who were kids in that period
Others copied the technique and a cult music genre was born
People still create SID chords on emulated C64's to this day, since the machine is long gone in the anals of history

Background & history

Personal POV

Being brought up with acoustic instruments of all kind, I know how good and a great instruments should sound
I have perfect pitch
I can hear up to the 1/100 of a Hz if a instrument is in tune
It's annoying when instruments are out of tune for me.
That distuned instrument, sounds like a kakaphony of cats squealing making the played music horrific in my head
I came with a high level of raw musical talent enabling me to easily pickup all different kinds of acoustical instruments
Behind a piano, without any formal training, I could easily play a song in minutes with the chords and the lead tune in a good manner
I loved to play on the electric bass, so the bass track which I first compose in my head, when I play the piano, is played in sequence
I would then pickup one of the brass instruments (I love the Tenor Sax) and play the lead well in munutes too
All that was left was playing the chords on any synth or keyboard available (usually one of the Korg or Yamaha synths)
I can hear and mix the levels of instruments in my head
It's easy to remix a sound in my head without having to touch a mixing console
All of these talents combined give me good insights in music as a whole and computer (SID music then) as a detail
I can work on electrical equiment on the pcb level, something I picked up as a young kid
From the age of three I disassembled tube radios with expert precision, making me fluent in the disassembly and assembly of tube radios
I assembled them back in working order from the age of four, after complete disassebly!
This gives me great insight in the hardware level of electronics

Last Ninja+

I naturally dismantled my C64 again when I heard the game.
Why did the game sound that way from a hardware POV
What makes the IC tick
I've got the manuals of all the IC's
I had already replaced the PLA906114 Program Logic Array with a new one on a socked, with no qualms
The PLA9016114 got too hot in the tropics (max temp 70C) so it never lived long without a heat sink.
My PLA's were programmed by a friend of mine who was an expert in the programming field
The new PLA's came blank
I did all the extraction, socked soldering and other work myself

The answer was in the C64 hardware manual

SID does just 8 bit audio
has zero polyphony
a limited frequency range both low and high
has scratchy output (which I later learned to appreciate)
has monophonic, single channel analog output
is in actuality a fair sounding IC but far from great

The Yamaha 8 bit sound IC of that period was much better

Yamaha had less succes than the SID for a simple reason

Mass deployment

SID was everywhere!
C64 machines were sold like warm bread in the morning at the old baker
Mass deployment means much more software programmed for the IC
SID won on mass deplyment and lower price in comparison with the lead 8 bit Yamaha audio IC of that period
The ammount of games making use of the SID was staggering in comparision
Games drove the success of the SID to astronomical heights
I got used to the SID, later seeking it's sound when I transitioned to my Amiga A500 with

Paula

Paula is polyphonic with 16 bit (14 bits actually) sound
Paula sounds much cleaner
has 4 channels 0 1 2 3
hard panning of channels in the stereo analog output
more stability
more joy

Motivation for seeking SID after it was gone...

Simple
NOSTALGIA
We all have it
even kids do

C64 SID

The SID CMOS IC in the C64 delivers an interesting eight bit sound colour in the C64

When I first heard the C64 SID as a kid it was nothing to throw your hat at. I've had experiences with concert piano's, tenor saxophones, percussion instruments in the electric range professional synths, bass guitars so I knew this bleep bloop ssshtt IC could never sound the way of the pro musical hardware, especially not the acoustic instruments.

Last Ninja I

It was when I heard the music of Last Ninja I knew that with it's severe limits, the Sound Interface Device has something special to offer. The composer of the music of this game did something marvelous.

He used arpeggio techniques to make the SID play chords

SID does not play polyphonic sound
Arpeggio gives the illusion of chords due to the rapid succession of notes played
Iconic music was spawned with Last Ninja
Unique arpeggio chords created on the SID are still seeked by those who were kids in that period
Others copied the technique and a cult music genre was born
People still create SID chords on emulated C64's to this day, since the machine is long gone in the anals of history

Background & history

Personal POV

Being brought up with acoustic instruments of all kind, I know how good and a great instruments should sound
I have perfect pitch
I can hear up to the 1/100 of a Hz if a instrument is in tune
It's annoying when instruments are out of tune for me.
That distuned instrument, sounds like a kakaphony of cats squealing making the played music horrific in my head
I came with a high level of raw musical talent enabling me to easily pickup all different kinds of acoustical instruments
Behind a piano, without any formal training, I could easily play a song in minutes with the chords and the lead tune in a good manner
I loved to play on the electric bass, so the bass track which I first compose in my head, when I play the piano, is played in sequence
I would then pickup one of the brass instruments (I love the Tenor Sax) and play the lead well in munutes too

I bought a #Hangell (no, I wasn't familiar with that name) switching bench power supply and it arrived. It happens to be one that #BigClive just briefly showed in one of his unbagging videos.

I got it because my existing old #linear supplies max out at around 18 V, and that has been a hindrance of late. A #switching supply isn't ideal, because of the possibility of noise, but this model will do 5 A at 60 VDC, and a linear supply that can do a couple of amps at that voltage is big, heavy, and pricey.

So of course, as soon as I received it, I took it apart. As you do.

And ... I'm pleasantly surprised. The #PCB layouts look good, the assembly appears very good, with proper pick&placed #SMT components and reflow soldering, not hack-job hand soldering. The components seem to be #quality, even name-brand where appropriate. There are what appear to be genuine class X and class Y #safety capacitors everywhere they should be. The front binding posts are fairly typical cheap #Chinesium ones, but appear to be from the better end of the quality spectrum as far as those go.

One ding: the multiple #electrolytic output caps appear to be 63 V-rated ones. For a supply that goes up to 60 V, that's just not acceptable. Maybe that's because this unit can also be had in a 30 V model? Or maybe they're just hoping you don't notice.

I'm sorely tempted to replace them with 100 V-rated ones before I use it. I'm going to add some more output #filtering as well.
