zaf··on Springer Textbooks More Than 10 Years Old Available for Free Legal Download
Well it's understandable.

While most of us are in the middle of holidays theres some poor soul beavering away trying to implement some feature before the "end of the year" deadline and tapped the wrong combination of keys and bam! the bank account graph starts dipping and crap hits the fan.

Hey, why don't you read some of the theoretical security / programming books that your company publishes?

-11 to Springer.

zaf··on Springer Textbooks More Than 10 Years Old Available for Free Legal Download
This is simply fantastic. I'm sure all publishers will follow. +1 to Springer.

Here is my current read:

Alan Turing: Life and Legacy of a Great Thinker http://link.springer.com/book/10.1007/978-3-662-05642-4

zaf··on Unfolding the 8-Bit Era: 8 players, 8 projectors, and one NES [video]
That is pretty cool. I suppose the "8-player" does not mean simultanioues 8-players but probably 4-player max what the NES can do and there is some multiplexing going on (using an Arduino) so you can have more people round the table for crowd control. Ah, yes, found the setup diagram:

zaf··on Raspberry Pi Zero: the $5 computer
All sold out!

Wanted the MagPI Magazine with a free RPi Zero but its sold out!

zaf··on Smallest RPN Calculators
Thats cool. I wonder if they are programmable... I have a HP12C which still feels great.
zaf··on Writing a Game Boy Advance Game
There are many articles on the web with lists of great games.

I've had great success with Super Mario Kart, Dynablaster etc..

zaf··on The Long Life and Quiet Death of True Detective Magazine
And I was just flicking through online at archive.org and found a bunch scanned:

Love the covers...

zaf··on Test versions of IE from 6 through 11 and Microsoft Edge using virtual machines
Amen. Thank the heavens for having choices in far superior computing environments.

I'm always shocked at what windows users have had to go through in the last 15 years.

I was getting warmed up to windows 10 but the recent privacy issues have got me cold again.

zaf··on Test versions of IE from 6 through 11 and Microsoft Edge using virtual machines
I've been using this for the last 6 months as part of cross browser testing and it has been a life saver. The alternatives are even a bigger pain in the rear.

I have no idea who to thank but thank you.

zaf··on FireTcl: Tcl embedded in Firefox browser
Well, Lua is moving fast and is lightweight and Tcl is a heavyweight and moving slow.

So the momentum is about the same and therefore both are relevant.

zaf··on Assembly 2015 demo party results
Entering manually (HTTPS) https://www.assembly.org/blogs/2/posts/24/ works...?

Why would you get a redirect?

EDIT: on safari it doesn't but firefox it does redirect...

zaf··on I made a cell phone [video]
Hey, great talk and thanks for the link to the paper.
zaf··on Oliver Sacks: Sabbath
I can confirm from experience that restricting computer/electronics use on Saturdays does wonders.

Currently am going further and practicing to include fasting on Fridays and 'Village' on Sundays to complete the mystical triad.

Four-day week with the rest as my own personal projects! Yea!

Simple ritual hacks that help in keeping my feet on the ground.

zaf··on Why the Greenwich meridian moved
Ha, just a month or two ago I was asking one of the local experts about the exact same thing.

It got so technical that he advised me to continue my enquiries with the astronomers at the Royal Observatory.

Unfortunately it was a Saturday morning and, as you know, they were all in bed after yet another crazy all nighter.

zaf··on Digital Bodleian Library
Excellent news.

FYI: The interface uses double click to navigate to the high res scans.

zaf··on Career Advice for Engineers and Designers
> Some programming tasks are especially suited to states of flow

Thats as close a match I found to "Programmer" vs 10 for "engineer".

zaf··on Eigenvectors and eigenvalues explained visually
D3 and MathJax

zaf··on Greek Debt Crisis Deal Is Reached, but Long Road Remains
> so how come I'm not hearing of lots of outside money moving in to buy hotels, resorts, etc.?

In the leisure industry that'e been happening big time on the Premium level for the last 10 years and now slowly at the Luxury level.

As for European/Global industrial powerhouses it's always been the red tape and government agency middle men that has been the main friction for moving in.

Whats happening is that these hassles are being removed as Greece gets more in line with European regulations.

zaf··on Don't use || to set default values in JavaScript
And what about the check for 0? Or does the empty string handle that case as well?
zaf··on Don't use || to set default values in JavaScript
> The only practical consideration raised is the falsy types can trip you up but that is easily negated.

You mean adding an if block to check for the zero and blank string?

zaf··on Toys from Trash
My favourite is the Homo Polar Motor:

http://www.arvindguptatoys.com/toys/homopolarmotor.html

So simple yet so magical.

zaf··on Toys from Trash
Great resource.

Discovered the site several years and helped in creating an offline version (only iOS) with all the content (as of 2012):

zaf··on Show HN: Fast and Extensible Parser for Markdown in PHP
I've worked with several markdown implementations and parsedown is my current choice due to my main constraint - speed. Great work and thanks for sharing.
zaf··on Sparkfun offering discounts on Arduino day
You could try codebender ( https://codebender.cc/ ) which is a browser based IDE that requires a simple browser plugin to be installed to communicate with your arduino.
zaf··on It's Behind You: The making of the game R-Type on the ZX Spectrum
Can't wait to read the PDF! Thank you Bob.

One of the best games ever and an unbelievable ZX Spectrum port.

I still remember holding and reading the box cover from the shops to my home.

And, shameless plug, this is what I did for my summer vacation project: "R-Type Real Time Memory Visualisation" ZX Spectrum http://zaf.io/page-3o.html#p139

zaf··on Starting Forth – the classic Forth language tutorial
Ah, so you mean that certain words can not only look at the stack but also look at manipulate the input word stream.

Thanks for the explanation. I really ought to do a practical session with Forth.

zaf··on Starting Forth – the classic Forth language tutorial
I've just recently started to dig into stack-based programming languages and would love to get hold of the Leo Brodie manuals.

One question to programming language experts: Is it possible to have a stack-based programming like forth but without the need for the extra characters needed in the syntax (like quotes, brackets etc..) and only use whitespace to separate the 'words'?

zaf··on Retro Gaming with Raspberry Pi
Thank you for writing the code and sharing it - super useful for many projects I'm sure!
zaf··on Forget flat design. Design in a 1995 style for full impact
Yeah, I saw that to.

Tried finding clues who does the website but no luck after first scan.

zaf··on ScummVM ported to HTML5 - play old games in your browser
Excellent project!

Graphics for Monkey Island in Safari on a Mac seem to be corrupted.
