Hyundai 45

2019 Hyundai 45

(Final Sliding Door)

Hyundai Motor Company unveiled 45, an electric vehicle concept, at the 2019 International Motor Show in Frankfurt.

Very nice, sleek and minimalist.

And a nice simple interior.

Z3

Konrad Zuse, a German engineer (b. 1910) died on this day in 1995. He designed the Z3 computer.

The Z3 was the world’s first working programmable, fully automatic digital computer. It was built with 2,600 relays, implementing a 22-bit word length that operated at a clock frequency of about 4–5 Hz. Program code was stored on punched film. The initial values were entered manually.

The Z3 was completed in Berlin in 1941 but was not considered vital, so it was never put into everyday operation. Based on the work of Hans Georg Küssner’s “Program to Compute a Complex Matrix” it was written and used to solve wing flutter problems.

Zuse asked the German government for funding to replace the relays with fully electronic switches, but funding was denied during World War II since such development was deemed “not war-important”.

The original Z3 was destroyed on 21 December 1943 during an Allied bombardment of Berlin. The Z3 was originally called V3 (Versuchsmodell 3 or Experimental Model 3) but was renamed to not be confused with Germany’s V-weapons.

A fully functioning replica was built in 1961 by Zuse’s company, Zuse KG.

 

Chrysler Portal

Looking for sliding doors ?

Forget the Peugeot 1007, or the Honda Vision XS-1, here it is..

The Chrysler Portal

The important features:

    • Electric Drive.
    • 400km range on a full charge.
    • 350kw DC Fast Charge.
    • Track-mounted seating that can fold flat, slide the full-length of the vehicle or be removed.
    • Sliding, Illuminated, portal-shaped articulating front and rear doors for easy loading/unloading.
    • In-vehicle wireless network enabling seamless integration of personal devices.

Fortran

In 1956 FORTRAN, the first modern computer language, was first shared with the coding community.

The Fortran Automatic Coding System for the IBM 704 (15 October 1956), the first programmer’s reference manual for Fortran

This was the first computer programming language I used (circa 1977). We didn’t have computers at school, programs were written out in longhand and transcribed to punch cards.

These were collected and sent to a mainframe that ran the program and printed out the results in wide,  punched paper.

The IBM 704 mainframe, which used FORTRAN language

Most of our work was returned where a single punching error, had terminated the program. Just to get a list of the first few prime numbers was an achievement.

The Adventures of Bertram Fiddle
Episode 1: A Dreadly Business

I first came across this from episode 73 of Smashing Security

This is a Victorian murder mystery game, available on steam and for the Android. It was installed on my tablet at the time (April 2018) and while briefly played, never finished.

With a (little) help from a walk-through the game was completed in an afternoon. It’s a fun little game, with lots of silly wisecracks and puns, mostly referencing things in the 20th century.

Episode 2 Continues the story…..

 

Prog Day

Today is International Day of the Programmer.

In 1956 The IBM 305 RAMAC was introduced, the first commercial computer to use disk storage.

 

Then, in 1985 Super Mario Bros. is released in Japan for the NES, which starts the Super Mario series of platforming games.

 

Comp Bug

On this day in 1947 a moth lodges in a relay of a Harvard Mark II computer at Harvard University, causing the first case of a computer bug.

The Harvard Mark II, also known as Aiken Relay Calculator, was a computer built under the direction of Howard Aiken and was finished in 1947. It was financed by the United States Navy. Howard Aiken and Grace Hopper worked together to program and build the Mark II.

 

PC Birth

The IBM Personal Computer, commonly known as the IBM PC was introduced on August 12, 1981. It was created by a team of engineers and designers under the direction of Don Estridge of the IBM Entry Systems Division in Boca Raton, Florida.

TBL & WWW


On August 6, 1991, Tim Berners-Lee posted a short summary of the World Wide Web project on the alt.hypertext newsgroup, inviting collaborators.

This date is sometimes confused with the public availability of the first web servers, which had occurred months earlier.
