OpenSTEM: People of ENIAC: early digital computer programmers

Sat, 2016-02-13 11:29
Without any real training, they learned what it took to make ENIAC work – and made it a humming success. Their contributions were overlooked for decades.

ENIAC, one of the world’s early digital computers (Colossus in the UK was earlier, for example), unveiled 70 years ago Sunday at the University of Pennsylvania, had six primary programmers: Kay McNulty, Betty Jennings, Betty Snyder, Marlyn Wescoff, Fran Bilas and Ruth Lichterman. They were initially called “operators.”

In this video, Kathleen McNulty Mauchly Antonelli talks about her time in the 1940’s learning about the ENIAC. She was one of a group of 6 women who were recruited to program this electronic computer.

Please note that the referenced article’s title incorrectly declares ENIAC to be the world’s first electronic computer. This is historically incorrect, with Colossus at Bletchley Park in the UK used for code breaking during WWII, and Konrad Zuse’s Z2 / Z3 in Germany.

Chris Neugebauer: Talks from linux.conf.au 2016

Fri, 2016-02-12 21:25

I spoke at linux.conf.au 2016 in Geelong! Once during the main conference, and once during the conference close.

Welcoming Everyone

My main conference talk, Welcoming Everyone: Five Years of Outreach and Inclusion Programmes at PyCon Australia, a five-year retrospective of how we’ve done outreach and financial assistance at PyCon Australia. It’s important that we share knowledge about how we run programmes that increase the diversity of our communities, and PyCon AU’s example shows how to build and grow such a program.

lca2017 handover talk

During the conference close, I gave our handover talk for linux.conf.au 2017, sharing what we think Hobart has to offer for the conference, and our vision for the conference. If you want to find out, in 6 minutes, what we’re planning on doing next year, this video is a good way to do just that.

Chris Smart: Trusting a self-generated CA system-wide on Fedora

Fri, 2016-02-12 12:29

Say you’re using FreeIPA (or perhaps you’ve generated your own CA) and you want to have your machines trust it. Well in Fedora you can run the following command against the CA file:



# trust anchor rootCA.pem

OpenSTEM: Gravitational waves have been detected, Einstein was right | Science Alert

Fri, 2016-02-12 09:30

http://www.sciencealert.com/live-update-big-gravitational-wave-announcement-is-happening-right-now

After 100 years of searching, an international team of physicists has confirmed the existence of Einstein’s gravitational waves, marking one of the biggest astrophysical discoveries of the past century. It’s a huge deal, because it not only improves our understanding of how the Universe works, it also opens up a whole new way of studying it.

Craige McWhirter: LCA2016 Revisited - Fuzz all the things

Fri, 2016-02-12 07:50

I actually saw this talk by Erik de Castro Lopo but didn't write about it as I arrived late and ended up sitting within arm's reach of the lectern... that and to be honest it's taken me this second viewing for it to sink in anyway.

With focus a on C / C++ Erik used his experiences with libsndfile and FLAC to provide examples of fuzzing.

The fuzzing technique provides:

  • A method to test a program with random input.
  • Provide a great leap forward in effectiveness.
  • Allows you to find bugs before they're reported.
  • Recommends AFL (American Fuzzy Lop)
  • Spends some time walking through how AFL works and how to use it.
  • Walked through sanitizers.
  • Provides a demo you can clone from git and use.
  • Covered the pro and cons rather extensively.
  • Took a walk through some SSH code as example of code not designed to be fuzzed and to underscore coding with fuzzing in mind from the start.
  • Provided a live demo and other cases.

An excellent talk, well worth watching if this is your field of endeavour.

Craige McWhirter: LCA2016 Revisited - Using Linux features to make a hacker's life hard

Thu, 2016-02-11 08:18

This talk by Kayne Naughton was the most talked about talk that I did not see while at LCA2016 in Geelong, so naturally it's the first talk I've watched revisiting the conference.

The allotted 40 minutes was clearly not long enough for Kayne to delve into his obviously deep knowledge of security in general and specifically the Linux space.

What resulted was a faced passed, informative, insightful and humorous take on Linux security, how to do it properly and how to effectively deter most would be hackers.

There's some genuine laugh-out-loud moments and plenty of 'oh's as Kayne drops the penny for us more than once.

A great talk that lived up to it's at-conference reputation.

This is another book I read as a teenager and decided to re-read. Frankly, its great. Confused teenager signs up for the British Army (or is conscripted, its not totally clear) and ends up as an artillery gunner. Has hilarious adventures while managing to still be a scrawny nerd. I loved it. A light hearted look at a difficult topic.

The reviews online for this book aren't great, and frankly they're right. The plot is predictable, and there isn't much character development. Just lots and lots of blow-by-blow combat. It gets wearing after a while, and I found this book at bit of a slog. Not recommended.
