deltasquared··on Putting email in its place with Emacs and Mu4e
Yes! Org-table is a spreadsheet. org-babel will run SQLite and gnuplot.
deltasquared··on Org-social is a decentralized social network that runs on Org Mode
This filtered out those who 1) don’t use eMacs 2) don’t use org-mode

I suspect org-mode users are willing to go through an extra step if needed.

My notes are in .org if I want to share with someone else I export to .md and use the output

deltasquared··on “Support for System V scripts now deprecated; will be removed in future release”
People may not trust systemd because years ago there were some really bad defaults like https://github.com/systemd/systemd/issues/2402 that for instance mounted your firmware in read write mode by default.

That kind of thing leaves a bad taste in some peoples mouth. I am pretty sure some people have bricked hardware with systemd.

deltasquared··on Show HN: I may have created a new type of puzzle
Thanks for your wonderful books. You have been an inspiration.
deltasquared··on Sampler for Mac Touchbars
For Vim use, I map caps lock to esc. This is built into osX under settings -> keyboard -> Modifier Keys...
deltasquared··on The x86 Advanced Matrix Extension
I am wondering why I would want this on a CPU when this kind of processing is already available on a GPU.
deltasquared··on Numerical Linear Algebra for Programmers
It lost me at no C++ at all.
deltasquared··on Grassmann.jl A\b 3x faster than Julia's StaticArrays.jl
I agree, the subtle difference between the physics and math mindset is interesting. I wound up on the sidelines as a computer scientist who worked in a physics lab.
deltasquared··on Grassmann.jl A\b 3x faster than Julia's StaticArrays.jl
I do have a bit of physics in my background. I read about Grassmann recently in a game programming book. Foundations of game engine development Volume 1 By Eric Lengyel ends with a nice explanation of Grassmann algebra.

The road to reality by Roger Penrose also has a treatment of Grassmann algebra in physics context.

I agree the library is likely a reference to the mathematician.

deltasquared··on Grassmann.jl A\b 3x faster than Julia's StaticArrays.jl
This is a pretty neat trick, they implemented exterior algebra see https://en.wikipedia.org/wiki/Exterior_algebra

You see this kind of math in textbooks focused on computer graphics.

deltasquared··on Introducing Swift
It does look a bit like Dylan. I wonder if it has more than a passing resemblance. Also I wonder if they are doing SBCL real time compelling.
deltasquared··on An autocompletion daemon for Go
That project just made my day!
deltasquared··on Amazing Dice: Rediscovering surprise
Non transitive dice are really fun.

If you want a jumping off point, I wrote some simulations with this set of dice in python. The source [0] is on github.

deltasquared··on Decompiling C# (async/await)
Surprisingly, you don't have to wait for Roslyn.

The technique exists now [0]. It is kind of a pain to use and seems kind of dangerous to use as a web app. But it is there. I messed with this a few years ago.

deltasquared··on Decompiling C# (async/await)
It is neat that C# has some standard macros defined. It would be nicer if it was more explicit what is going on behind the scenes. I would love to see the equivalent of c-macro-expand. [0]

Also, although it is possible to extend C# using stuff like custom linq providers, [1] I still prefer lisp style macros.

deltasquared··on Google Announces $1,299 Chromebook Pixel With 2560×1700px Touchscreen
And this is why I am always suspicious of an IDE. This sounds like a really nice way to talk to a Linode to develop on.
deltasquared··on Sorry, Geeks, Microsoft Excel is Everywhere
I wonder if by geeks, the OP means "people who want to get the correct answer consistently."
deltasquared··on Five days with Pebble
Well if you want to start with the previous product, the inPulse, they have an SDK here: http://getinpulse.com/pulsesdk/

They have a simulator and some nice code samples. It is a fun C api and simulator. I am not sure when they will release the SDK for the Pebble.

deltasquared··on Critic Markup: Plain-Text Editing Markup for Humans
Well if anyone wants an emacs mode for this: (require 'generic-x) ;; we need this

(define-generic-mode 'critic-mode nil nil '(("{--.--}" . 'font-lock-warning-face) ("{~~.~~}" . 'font-lock-constant-face) ("{{.}}" . 'font-lock-keyword-face) ("{>>.<<}" . 'font-lock-function-name-face) ("{\+\+.*\+\+}" . 'font-lock-type-face) ) nil nil "A mode for foo files" )

deltasquared··on Critic Markup: Plain-Text Editing Markup for Humans
Nice idea. It seems pretty easy to understand. Where is the emacs mode?
deltasquared··on [dead]
It is true that 2 multiplied by it's self 57,885,161 times is not prime. However, if you subtract 1 from that the result is prime.
deltasquared··on Kinda like apt-get, but for Windows
I do not think apt-get means what you think it means.

Chocolatey seems to implement a subset of the functions that apt-get is useful for.

On Windows if I want to look for system updates, I use Windows update. On Debian I use apt-get.

On Windows if I want a library to use on a project, I use NuGet. On Debian I use apt-get.

On Windows if I want to install a bunch of free applications, I probably will use ninite, but chocolaty looks like a nice replacement for this. On Debian I use apt-get.

That said chocolatey seems like a nice tool for windows.

deltasquared··on How SublimeText Bodybags vim+Terminator
I agree, work over ssh or go home.

I am pretty sure I will be using Vim when Sublime goes the way of Textmate and SlickEdit.

deltasquared··on How A Pull Request Rocked My World
Yup. I remember that particular realization. Now switch statements in OO languages just look broken to me. Thanks Python!
deltasquared··on Why extroverts fail, introverts flounder and you probably succeed
Something sounds off here.

At face value the article is saying. If most people are "ambiverts" and ambiverts make the best sales people, and sales people are the best leaders, why are there not more leaders? Why is it that most people are not in charge.

Finding out that there is no correlation between extroversion and sales performance is interesting and all but I think it would be better to find a new scale to use, one with positive correlation for what you are looking for.

Pointing out that people's scores for extroversion fall along a normal distribution, and that people's sales preform aces fall along a normal distribution does not really say much.

Typically, a low correlation score means your model is wrong, not that you need to fix your model by choosing a different locus.

deltasquared··on Javascript Cryptography Considered Harmful
What is magical about C code, or asm, or microcode that makes it more secure? Everyone has to trust someone. See the Ken Thompson hack: http://c2.com/cgi/wiki?TheKenThompsonHack
deltasquared··on Hydrogen made with muons reveals proton size conundrum

deltasquared··on What It's Like To Be Ridiculed For Open Sourcing A Project
I don't understand, not the critics, not the project.

Why insult something that someone obviously put a lot of care into?

The code is nicely formatted and clear. I can see how it works. Props to harthur for making something easy to read and then sharing it on Github. Both readable code and sharing should be encouraged.

I don't really get why someone would want to implement text processing utilities in node.js. It seems to be a bit heavy on the overhead.

Might someone re-implement harthur's user interface (which a bunch of people seem to like) in c, and submit it to the GNU Coreutils project?

deltasquared··on Unlocking Cellphones Becomes Illegal Saturday in the U.S.
Yeah, I have switched out SIM cards on my travels.

When I Had a locked phone, I would keep it on Airplane mode for the duration of my trip.
