Vintage technology is the future of enterprise IT

What turns weakness into catastrophe is monoculture. All software has flaws, all systems have weaknesses, and you design around that by having multiple different systems with different weaknesses. If the world’s banana crop is a single strain, then a single pathogen can take out the lot.

You’re not going to harden your IT infrastructure by rewriting Active Directory in FORTH under VMS, much as such an exercise may appeal to the more perversely creative. But the more experience you have of seeing things done differently, of analyzing and understanding systems that don’t make the current industry standard assumptions, the better you’ll be at assessing and working with different contemporary options.

Atkinson Hyperlegible Font is a font designed with low vision readers in mind.

The Braille Institute has developed a font - free to download - that’s designed to be clearer for readers with lower vision.

An example of one of the aspects of low legibility that they tackled attached.

It’s named Atkinson Hyperlegible. Here’s where you can read about the font and download it: https://brailleinstitute.org/freefont

Der ewige Zombie: E-Voting

Die leicht tendenziöse Semesterfrage „Digitalisierung”, die im Rahmen einer „entgeltlichen Einschaltung in Form einer Kooperation mit der Universität Wien” im Standard ist ein trauriges Blitzlicht auf den aktuellen Stand der digitalen Grundbildung in Österreich.

Insbesondere die zweite Frage „Was spricht gegen die Einführung von E-Voting – die elektronische Stimmabgabe bei Wahlen – in Österreich?”, bzw. genauer gesagt, die „richtige” Antwort darauf, lässt die Wissenden die Hände über dem Kopf zusammenschlagen. Die „korrekte” Antwort laut Universität Wien und Standard wäre nämlich:

Beim E-Voting können Manipulationsversuche gut erkannt und das Wahlgeheimnis gewahrt werde, allerdings stehen Österreicher:innen dem digitalen Wählen skeptisch gegenüber.

In der Begründung wird dann auf einen entsprechenden Text der Uni Wien verlinkt. In diesem Text wird der sicherlich sehr schlaue Hr. Univ.-Prof. Dipl.-Ing. Mag. Dr.techn. Edgar Weippl, der natürlich rein zufällig vor allem zu Blockchain- und Distributed Ledger-Technologien – den zwei Technologien, die noch immer die Probleme suchen, die sie lösen wollen – forscht, wie folgt zitiert:

Kann man E-Voting überhaupt sicher umsetzen? Ja, meint Edgar Weippl, das kann man. Beispielsweise mithilfe der sogenannten „homomorphen Kryptographie”, bei der jede Person selbst überprüfen könne, ob ihre Stimme gezählt bzw. alle Stimmen korrekt addiert wurden.

Ich mein, ich bin sicherlich weder der dümmste, noch der gescheiteste Mensch auf dieser Welt, aber wenn ich mir Homomorphe Verschlüsselung auf Wikipedia durchlese und mir dann z.B. „Λ ○ λ”, eine Haskell library für (Fully) Homomorphic Encryption aus der Liste auf Github raussuche, kann ich nicht selbst überprüfen, ob damit alle Grundsätze des freien, geheimen und persönlichen Wahlrechts erfüllt wurden.

Und genau diese Überprüfbarkeit listet auch der österreichische Verfassungsgerichtshof in seiner Entscheidung vom 13.12.2011 „V 85‐96/11: E-Voting bei ÖH-Wahl gesetzwidrig” in seinen Bedenken:

… von Bedeutung, dass die wesentlichen Schritte der Wahlhandlung und der Ergebnisermittlung von der Wahlkommission zuverlässig und ohne besondere Sachkenntnis überprüft werden können müssen.

Ich denke nicht, dass Verständniss von homomorphen Kryptographie und die dazugehörigen Programmierkenntnisse als „ohne besondere Sachkenntnis” durchgehen. Vor allem, wenn die Alternative „Papierzettel nach Kreuzchen sortieren” ist.

 

Aber genau so wird Stimmung gemacht, um über kurz oder lang den feuchten Traum der ÖVP und deren angeschlossenen IT-Dienstleister und IT-Consulting-Unternehmen, manipulierbares e-Voting in Österreich endlich zu etablieren, doch noch zu realisieren – weil es ist ja „sicher”.

“Logic and Argumentation for the 21st Century”

On 14 January 2023, we celebrate World Logic Day. In the city of Kurt Gödel, Ludwig Wittgenstein, and the Vienna Circle, mathematical logic and its application to the sciences have a long and rich tradition. This January, we welcome Dov Gabbay (King’s College London and University of Luxembourg) as speaker at the Vienna World Logic Day Lecture.

The third edition of the lecture series is welcoming Prof. Dav Gabbay who will talk about “Logic and Argumentation for the 21st Century”.

The WELL: State of the World 2023: Bruce Sterling and Jon Lebkowsky

Personally, I didn’t come to any particular harm by the quarantines.
I had good fortune, they weren’t traumatic times for me. What were
those times like? They were "like nothing else," but also they were
remarkably like "nothing." They felt somewhat like a general strike
or a hurricane evacuation, but they also had this novel sci-fi
vacuity to the textture of the days. Huge, surreal absences. The
lack of transport nose and any sky-contrails was a big aspect. The
people were in hiding from one another, but also the big machines
were absent and silent.

The value of one consulting firm’s federal contracts has skyrocketed under the Trudeau government

In Österreich würde ich so eine Studie ja gerne mal für Accenture sehen …

Smart cities

This was a hopeful slogan to unite a scattered series of approaches
to urbanism. There’s no unifying "smartness" there. Google being
ignominously chased out of Toronto with pitchforks was probably the
Waterloo for this.

The WELL: State of the World 2023: Bruce Sterling and Jon Lebkowsky

Web3, NFTs

It seems pretty clear now that this impressive craze was not so much
"blockchain art" as "lockdown art." It’s what art people do
culturally when they’re not allowed out of the house. One of the
most entertaining cultural freakouts I ever personally witnessed,
but it was convulsive and in many ways quite sad.

The WELL: State of the World 2023: Bruce Sterling and Jon Lebkowsky

In 02023, people are becoming poorer, their lifespans are shorter;
food costs more, and housing is worse. You’d think there would be
more focussed, radical indignation about such an obvious bad scene
– a culture in visible decline – but the temper of the times seems
to welcome it, somehow.

I don’t like begin a year with gloomy, elaborate whining; that like
a privileged luxury that people have when Mom’s not chased in exile
and Dad’s not under arms in a trench. And yet, I do realize that
my customary futurist speculative habits have become old-fashioned.
I’m from a tech-obsessed subculture, so it’s my habit to look for
scientific and industrial innovations and assume they’re gonna alter
the world’s situation.

That’s not what happens in this decade. I’m aware that I need
better methods.

The WELL: State of the World 2023: Bruce Sterling and Jon Lebkowsky

There’s something very Twenty-Twenties about attempting and failing
to "turn the page" on inconvenient truths that can’t and don’t go
away. That’s why each year tends to repeat the last. I wouldn’t
call that "moral cowardice," because people do not, and cannot,
really ignore the pervasive problems – they do see them, and tend
to complain quite consistently about the same issues, year after
year. But, without ever getting much done about them. It’s rare to
see any public problem that’s analyzed, agreed-upon, confronted,
dealt with and dismissed. All the "crises" tend to thrive, and to
mutate into long-term shambolic debacles. It’s a decade that feels
the need to marinate in its own distresses – doomscrolling as a
way-of-life.

"When you can’t imagine how things are going to change, things
change in ways that are unimaginable."

web0 manifesto

In other words, web0 is web3 without all the corporate right-libertarian Silicon Valley bullshit.

The Cursed Computer Iceberg Meme

This is why many people in IT drink heavily.

Inside the 8086 processor’s instruction prefetch circuitry

Caching and prefetching were used in mainframe computers dating back to the 1960s. For instance, the IBM System/360 Model 91 (1966) had a cache with prefetching. Minicomputers such as the VAX 11/780 (1977) later used caching and prefetching. However, these features took a while to trickle down to microprocessors. The Motorola 68000 (1980) had a 4-byte prefetch queue. As far as I can tell, the 8086 was the first microprocessor with a prefetch queue.

We can view the 8086 as a stepping-stone towards the large caches first used externally in the 80386 and internally in the 486. The 80186 and 80286 kept the 6-byte prefetch buffer size of the 8086. The 80386 has a 16-byte prefetch buffer, although apparently due to a bug it was shrunk to 12 bytes in later revisions. As well as the prefetch queue, the 80386 supported an external cache.
