@johnzajac @ohmu @RickiTarr @skribe let us not forget that all things have lifespans: you, me, and government programs (supposedly). But it seems we have already discovered eternal #life in the latter, as #systems that reach a certain complexity adapt/evolve just like biologic life.

I am currently in Switzerland where it seems #CERN #science #research lab has become an #energy #utility (the sign says waste heat from #LHC is heating homes in a nearby village)...go figure!

Hey, #FediHire me! 🥳
I'm looking for a decent #job, preferably remote.
Any help is appreciated.

I bring a ton of skills and more than a decade of experience as a #software #engineer, have been working mostly on #web #applications and some #mobile over the years, and done lots of #systems programming and #firmware in my spare time projects. 🧑‍💻⚙️

My main languages are Rust and JavaScript/TypeScript.
I'm based in Germany.

More details and CV are at dan.orangecms.org/.

Please #boost, thanks!

dan.orangecms.orgHi, I'm Dan!

actually it is insanely simple.

- there is no infinite exponential growth in a finite environment

- without the biosphere intact there is no human life

- every system that uses up its non -#renewable resources, depletes its renewable resources faster than the rate of replenishment, or pollutes its sinks faster than the rate of breakdown of pollution

Back of envelope theories of complex systems, as always with my mostly relating to off-hand comments Winograd made in the first page of his Breaking The Complexity Barrier (Again) paper.

What do you think?

Main feature is bootstrapping making these graphs somewhat in terms of themselves metacircularly.

brenda elthon’s short photo essay today contains a corker of a quote: (she is talking about 1968)

<<A US government scientist, speaking at a meteorology meeting, warned that burning petroleum and other organic compounds ‘to move a 120-pound woman and a bag of groceries to and from the market’ radically affects the Earth’s chemical balance and represents a long-term threat to human survival.>>

which calls to mind the observations of author john gall, who wrote about Operational Fallacies in his book General Systemantics in 1975

<<Example 1. Doesn’t the auto industry supply us with millions of new cars each year, even tailoring them to our changing tastes in style and performance?
Answer. The reason we think the auto industry is meeting our needs is that we have almost completely forgotten what we originally wanted, namely, a means of going from one place to another that would be cheap, easy, convenient, safe, and fast. We have been brainwashed into thinking that the Detroit product [cars] meets these requirements. >>

the auto industry has destroyed the face of the earth; it has dictated urban design, while the demand for oil has been behind a lot of global conflict. our economies revolve around cars. people are locked up in jails because they drove unregistered cars because they needed cars to get to work, and so on.

remember in the 1950s/1960s when suburbs all had reasonable public transport, and men (yep, blokes, mostly) still came to households delivering bread, milk, soft drink in glass bottles, collecting used glass bottles, flogging fish, sometimes rabbits, greengroceries etc?

then we got cars and started do-it-yerself shopping. thankfully, we are now reverting to some home delivery, but urban design is still a mess.

stafford beer was the bloke credited with saying The Purpose of a System is What it Does #POSIWID

<<there is "no point in claiming that the purpose of a system is to do what it constantly fails to do">> (i lifted this from wikipedia)

"Indeed, the phrase “what we make, makes us” captures a fundamental truth about the relationship between the act of altering our world and how it is we understand that world—we make the world over in the image of our thoughts. Thought, through sensing and perception and abstraction or conception, strives to bring order to our experience."

"The notion of a system is ubiquitous. It is not simply a technical concept but it lies at the heart of how the mind deals with and conceives of and understands the surrounding world. It is the essence of how we design and build or make things and how we ultimately garner assurance about their behavior."

"A system is a set of interacting components that frequently form a complex whole. Each system has both spatial and temporal boundaries. Systems operate in, are influenced by and influence their environment. Systems can be described structurally, as a set of components and their interactions, or by reference to its purpose. Alternatively, a system can be referenced in terms of its functions and behaviors."

in my opinion, any other description of what to do describes special-purpose advanced convenience functions. It /really/ is this easy.

I include #emacs #eev support (which is transparent to the common lisp if you are not using it) since having a lisp environment at all is somewhat inevitable to using lisp, and pressing F8 over and over again is pretty easy to do.

Thoughts!?

Here's a #Linux #networking question for you: what's a lightweight way to allow an HTTP request to an arbitrary *user*-provided FQDN, but to prevent the connection being made if the FQDN maps to an RFC1918/private IP address?

(The relevant command here is #curl, but I don't think that matters as it doesn't appear to have a flag to say "only connect if the IP is /not/ inside these subnets".) #sysadmin #devops #network #hostnetworking #sre #systems #platformengineering
