In eigener Sache: „Established 2023“
Zwei Jahre. 24 Monate. 730 Tage. So lange gibt es diesen Blog – und das nur, weil ich eigentlich nur für mich die Mediatheken durchforste, um Filme zu finden, die etwas riskieren. Filme, die weh tun, irritieren, begeistern, wütend machen. Filme, die nicht glatt gebügelt wurden, Filme für meinen ganz privaten Eskapismus. Ich schreibe darüber, weil sie mich beschäftigen. Weil ich etwas sehe, das nicht untergehen sollte im Strom der Flachware. Und weil ich glaube, dass Filmkritik viel mehr sein kann als Konsumberatung.

Il problema delle patate - Una storiella nata in Francia e raccontata da Lucio Russo nel suo "Segmenti e bastoncini" per esemplificare il tracollo della prparazione matematica negli studenti della scuolaPer mostrare un esempio del dibattito sul deterioramento dell'insegnamento scientifico, diffuso in termini analoghi in tutto il mondo occidentale, riportiamo la storiella del "problema delle patate", che, nata in Francia, è stata riproposta recentemente in Spagna. [Nota. Il "problema delle patate", ripreso da una rivista spagnola, è stato riproposto in traduzione italiana da Ana Millàn Gasca nel numero marzo-giugno 1996 di "Lettera matematica". Ho abbreviato leggermente il testo. Fine nota.] Si tratta della descrizione delle successive modifiche di un semplice problema di aritmetica.
1960.
Un contadino vende un sacco di patate per 1000 pesetas. Le sue spese di produzione sono i 4/5 del prezzo di vendita. Qual è il suo guadagno?
1970 (insegnamento "tradizionale").
Un contadino vende un sacco di patate per 1000 pesetas. Le sue spese di produzione sono i 4/5 del prezzo di vendita, e cioè 800 pesetas. Qual è il suo guadagno?
1970 (insegnamento "moderno").
Un contadino scambia un insieme P di patate con un insieme M di monete. La cardinalità dell'insieme M è uguale a 1000 e ogni elemento di M vale una peseta. Disegna 1000 grossi punti che rappresentino gli elementi dell'insieme M. L'insieme S delle spese di produzione è un sottoinsieme di M ed è formato da 200 grossi punti in meno di quello dell'insieme M. Rappresenta l'insieme S e rispondi alla domanda seguente: qual è la cardinalità dell'insieme G che rappresenta il guadagno? Disegna G in colore rosso.
1980 (insegnamento "rinnovato").
Un contadino vende un sacco di patate per 1000 pesetas. Le sue spese di produzione sono 800 pesetas e il suo guadagno è di 200 pesetas. Sottolinea la parola "patata" e discutine con il tuo compagno.
1990 (insegnamento "riformato").
Supponendo che degli agricoltori vogliano vendere un sacco di patate per 1000 pesetas, fai un sondaggio per determinare il volume della domanda potenziale di patate nel nostro paese. Completa questa ricerca analizzando gli elementi del problema, mettendo in rapporto gli elementi fra loro e cercando il principio del rapporto fra questi elementi. Per finire, fai una tabella a doppio ingresso, indicando in orizzontale, in alto, i nomi degli elementi citati, e in verticale, in basso, diversi modi di cucinare le patate.

S'è destra - Redistribuire violenza e non ricchezza
Valerio Renzi on Substack
La destra vince perché, pur non redistribuendo ricchezza, redistribuisce la possibilità di esercitare potere e violenza sul piano simbolico e materiale ad alcune porzioni di popolazione, che creano un blocco sociale trasversale e interclassista poten…Substack
Na ja, vermutlich ist das Industriezeitalter in 200-300 Jahren komplett vorbei, und der Kaputtalismus mit seinem bösartigen tumorhaften Wirtschaftswachstum kollabiert spätestens um 2050, wenn er überhaupt noch so lange durchhält. Interessant ist, wie schlimm die kumulativen Schäden an allen möglichen ökologischen Systemen dieses Planeten bis dahin noch werden. Wenn nur so 50-60% aller Spezies aussterben, stehen die Chancen sehr gut, daß hinreichend viele Menschen den Kollaps überleben, daß die Hominiden nicht aussterben. Wenn wir es so weit eskalieren lassen, daß 90% aller Spezies aussterben, dann verschwinden mit hoher Wahrscheinlichkeit alle ökologischen Nischen für große Landwirbeltiere, und das sind wir dummerweise halt auch. Egal wie es läuft, in 5-10 Millionen Jahren ist die Biosphäre wieder völlig normal, nur halt mit anderen Spezies, die aus den Überlebenden evolvieren.
Um Ameisen würde ich mir keine Sorgen machen, die haben diverse ganz gewaltige Massensterben überlebt. Selbst wenn die meisten Spezies von denen verschwinden, ist das nicht allzu schlimm für die Ameisen insgesamt. Problematisch ist eher, daß die verschwindenden Ameisenspezies alle möglichen Tiere und Pflanzen beeinflussen, und daß sich dort, wo sie verschwinden, andere Spezies breitmachen, die andere Einflüsse auf das lokale Ökosystem haben.

I run Firefox with uBlock Origin in my work as well as private device for > 2 years without any issues including tricky applications like Citrix, Virtual Desktops etc.
On my mobile, I use Fennec with uBlock Origin, Decentraleyes and PrivacyBadger and sometimes have some small issues, so I have to view the page in Desktop mode instead.

Using Clouds for too long might have made you incompetent
My take on how a decade (or more) of using cloud services for everything has seemingly deskilled the workforce.
Just recently I found myself interviewing senior security engineers just to realize that in many cases they had absolutely no idea about how the stuff they supposedly worked with, actually worked.
This all made me wonder, is it possible that over-reliance on cloud services for everything has massively deskilled the engineering workforce? And if it is so, who is going to be the European clouds, so necessary for EU's digital sovereignty?
I did not copy-paste the post in here because of the different writing style, but I get no benefit whatsoever from website visits.

Thank you! Great to see some lowering to technical barrier to entry for the Fediverse.
I believe the biggest barrier to entry for Lemmy is not a lack of features but the technical lingo required.

in reply to FundMECFS • • •I got firstnamelastname@gmail.com when gmail was still 'invite only'.
The one drawback to that is there is a General in the U.S. Army with my exact name who doesn't understand how email works and apparently gives out my email address as his. I wish I knew what his actual email address was so I could let people know what it is. I bet he's missing out on a lot of VA functions and barber appointments because he couldn't be assed to remember his actual email address.
