dhon_··on I Can’t See You but I’m Not Blind
I have aphantasia, although to a lesser degree to the author. Like you I can visualise 3d models in my head, but if I try to recall an image of someone it lacks detail. I can "fill in" detail by recalling facts about that person (hair/eye colour, wrinkles etc) but the image is blurry and details fade quickly.

I don't dream very much, though a few times a year I will have a very vivid dream (basically like a video in my head with lots of detail). This makes it very apparent that my normal imagination is lacking detail. It feels a bit like it's a different area of the brain that I don't typically use, and makes me wonder if I could use it more with practice.

One test for aphantasia goes something like this:

> Imagine a ball sitting on a table. You reach forward and push the ball and it rolls off the table. Now without changing the scene, what colour was the ball? What about the table?

For me the ball is smooth an white. The table is something akin to stainless steel. My wife will describe a colourful beach ball on a wooden table with lighting and shadow and describe the room it's in in detail. My scene was in a void as no room was mentioned.

dhon_··on Batteries included with Emacs (2020)
Well, apparently they do need to look at the screen :)
dhon_··on Windy.com
15C is 59F, 16C is 60.8F so I'd say using integer Celcius and converting to Fahrenheit
dhon_··on The Alexander: Why did you build such a long piano?
I originally thought The Giant was a modelled instrument (as opposed to sampled) because it looked like something out of a Studio Ghibli film
dhon_··on Localize your cat at home with BLE beacon, ESP32s, and Machine Learning
If you attach an IMU to your cat would it become blurry?
dhon_··on Robotic Manipulation (Online Textbook)
Thank you for Weekly Robotics, it's an amazing resource
dhon_··on A 60 GHz phased array for $10
Value to the end customer does not equate to value to the big company though. It could be that the products that were shut down were barely turning a profit.
dhon_··on Prusa MINI: Smart and compact 3D printer
What I love about Prusa is that they eat their own dog food. They use their printers in a farm producing parts for their products. This makes reliability and repeatability first class citizens.

He mentions in the blog post that the motivation for this was wanting smaller & cheaper machines for the farm, as two small machines can print faster than one big one for the same cost.

I'll still wait for reviews, but this looks like a great little machine and I suspect that quality will be reasonable for the above reasons.

One issue will be corrosion on the rails over time though. This affected an original Ultimaker I had sitting around as I let too much dust gather on it.

dhon_··on Everyone Has an Accent
I've heard a theory that the slow southern accent was due to a hookworm outbreak. So maybe historically at least there was some validity in the assumption.

dhon_··on Google Cloud Text-To-Speech Powered by DeepMind WaveNet Technology
Tacotron (also by Google) looks promising in this area https://google.github.io/tacotron/publications/global_style_...
dhon_··on Numpy: Plan for dropping Python 2.7 support
How is the Twisted Py3 support coming along in practice? It looks like they are steadily ticking items off the todo list, but is it ready for production use yet?
dhon_··on In love with the BBC micro:bit
What did you change to improve ESD resilience?
dhon_··on AI vs. MD: what happens when the diagnosis is automated
I suspect the reasoning from the algorithm would be a lot more specific than from a doctor given the same information. People don't have deep understanding of their reasoning process and (necessarily) make a lot of decisions based on a hunch. An algorithm would be able to tell you confidence ratings for multiple conditions and reasoning behind which treatment was prescribed or what additional tests were required.

I still feel that this is a tool that should be used by Doctors (rather than to replace them) as the reports will likely contain more detail than a layman would understand.

dhon_··on How we built a Smart Office system based on Raspberry Pi
Interesting, are they mounting the SD card read only?
dhon_··on Image Compression with Neural Networks
If it still features human responders then it will probably suffer the same issues. Maybe we can train neural networks to answer programming problems?
dhon_··on Wearable keyboard that turns anything you can touch into a typing surface
A wristband seems like a much less obtrusive way to accomplish this goal (tracking tendons or muscles in the forearm) and would be great integrated with a smart watch.

This looks promising http://www.smh.com.au/it-pro/business-it/writing-in-the-air-...

dhon_··on Wow, Perl 6 [video]
For anyone else that's confused - the linked page above is the presentation, but you need to use space or arrow keys to navigate.

Also, the URL at the bottom is broken (says TPM2016.zoffix.com but links to http://zoffix.com/TMP2016)

dhon_··on Why your first Rust FizzBuzz implementation may not work
Thanks, also is the "try it" link on rust playpen linking to the wrong code?
dhon_··on Why your first Rust FizzBuzz implementation may not work
In the contrived Python example, FizzBuzzItem is only called if the result is a number (not in any of the modulo 0 cases) - is that intended? I can see that it works, but it's breaking the analogy for me with the Rust code.
dhon_··on DEFCON Capture the Flag Qualification Challenge #1
> We can see that the bit in bold here was 0x0100 as var_14.

Should that be "0x01"?

Edit

> The null after the 0x1 is implied

Oh I see, strncpy stopped when it hit the (implied) null (0x00) character

dhon_··on Python with Braces
I don't understand, this is already available with

  >>> from __future__ import braces
dhon_··on How I Learned to Stop Procrastinating, and Love Letting Go
On a side note, I just listened to this audiobook "The Art of Procrastination: A Guide to Effective Dawdling, Lollygagging and Postponing"

http://www.amazon.com/The-Art-Procrastination-Lollygagging-P...

A humorous take on working with procrastination, not against it. Short, but highly recommended.

dhon_··on Cython 0.20
From https://github.com/cython/cython/blob/master/README.txt:

Cython (http://cython.org) is a language that makes writing C extensions for the Python language as easy as Python itself. Cython is based on the well-known Pyrex, but supports more cutting edge functionality and optimizations.

The Cython language is very close to the Python language, but Cython additionally supports calling C functions and declaring C types on variables and class attributes. This allows the compiler to generate very efficient C code from Cython code.

This makes Cython the ideal language for wrapping external C libraries, and for fast C modules that speed up the execution of Python code.

dhon_··on Python and Flask Are Powerful
Or use twisted python and throw simple out the window!

Kidding (sort of), twisted is great :)

dhon_··on Python and Flask Are Powerful
I think you're paying the $5 for getting the Python 2 & 3 versions of the book more so than the different file formats. After all, you could convert formats fairly easily.
