Inkscape is an amazing vector graphics editor. It is free and open source and works on a variety of platforms, including Linux, Windows and OSX. Inkscape replaces Corel Draw and Adobe Illustrator and can read their files, and is a first class citizen among these other editors.

Inkscape on OSX
Unfortunately the mainstream OSX release runs on xQuartz which is slow and doesn't support the standard OSX keystrokes and menus. Plus the windowing is not flexible enough. The main branch has continued development while the idea is to get a native release working with Gtk 3, but it is unclear if or when that will take place.
For years I have used an old 2013 release from Valerio Aimale. There is now a 2017 release for Inkscape 0.92.2 but it doesn't run on OSX 10.01 (Yosemite), so I am unable to test or use.
While s_uv is working on a next version of OSX with Gtk integration (called OSX Menu), it still is wrapped in xQuartz, with the same issues.
As of mid-2018 I no longer use OSX, so things may have changed since then.
Inkscape Features and Functionality
Inkscape Keyboard and Mouse Reference
I use Inkscape as a drawing and illustrating tool and also for editing images in terms of compilations, extraction and svg-ification, logos, book covers, basically everything under the sun.
As with any tool, getting efficient with Inkscape is a discovery process with a learning curve. As well, I happen upon a variety of features that continue to amaze, including:
Barcode generation: > Extensions > Render > Bar Code
Inkscape supports extensions including:
Inkscape Map Inkscape SVG files to HTML image map or coordinate list
The current system of analytics tracking is so very broken, let us count the ways:
Most solutions require third party trackers
These are easily blocked by third-party ad blockers/privacy tools
They are a privacy nightmare, even when implemented properly
They slow a site down by increasing http requests and the overhead of additional offsite requests
Most self-hosted solutions are equally bad
Most self-hosted solutions, including open source, require either a cloud service,
(again, the problems above),
or a full application with mysql as a database (large overhead for small, low-volume websites).
Return of Weblog Analysis
What is needed, with a bit of fine tuning, is a basic weblog analysis. After all, most of what is desired can be managed through http headers, including using session and tracking cookies, all accessible from well-configured weblogs.
In turn weblogs can be parsed and information structured and placed into additional logs and/or sqlite databases, which can then be accessed via clients for realtime or reporting data.
Apache log content available
Client IP address (which can be then compared with GeoIP)
Date/time of request
Here is where the meat and potatoes are located. Of course initial requests may not have cookie data, but subsequent requests certainly can, including session (encrypted even) and user tracking (clickstream) cookies, including encrypted usernames/passwords.
In my household we have been introducing Xiaomi products for the past six months. Overwhelmingly positive, but not without a hiccup here and there. In general, there is an odd mixture of: quality, design, and value. I say odd because generally those things don't go together. Great price, good looks, and works well. Not perfect, but nothing is. Xiaomi may have much bigger rivals, especially in China, but they have such a strong combination that they are able to compete with, and in some cases beat out such giants as Samsung in markets like India.
Colorblindness affects approximately 5-8% of the population, mainly males. The visualization of these kinds of colorblindness is eye-opening, to say the least.
The most common form of colorblindness is deuteranomaly, which is red-green. The colorblindness simulations show the color red as indistinguishable from a certain shade of green.
Actually to my eyes the dichromatic treatment renders both green and red as amber or ochre. Which means that yellow, orange, green, and red are seen as a light yellow to dark yellow spectrum, with purple as a darker form of blue.
This means that the use of red and green as distinguishably different should be avoided. The use of red-yellow distinctions or green-yellow distinctions could work.
Also now that the blue-purple distinction also gets muddled, which is not useful for the dark blue link and purple visited-link color standard in html.
There are three online marketing graphical components which should be made colorblind-safe
* Company logo and other visual brand design elements
* Website color scheme, including background, headers, subheads, links, and visited links
* Any graphical banner advertisements used anywhere on the web
Just like the company or brand name and website URL, which may not be changeable, the company brand colors and logos may be off-limits to optimization. However, any kind of navigation or non-core imagery should be viewed through the lens of the colorblind customer.
Rules of Thumb
Some rules of thumb can be generated from these research findings
* Do not mix green with either red or orange
* Use a darker green against light backgrounds, as light green appears as yellow
* Do not mix blue and purple, and avoid shades of blue to purple, they won't stand out
* Use the VischeckJ tool (below) which will show how differentiated a given logo and graphic scheme is from competitor brand visuals
As per the usual, the idea is to be different, but in a good way.
What does it take to create a new normal? For the body, to make regular exercise the default and not exercising the abnormal condition? By exercise I mean something well, meaningful.

Evolution is about adaptation (and natural selection) but the part most interesting is the adaptation that is possible in our individual lives. This does not mean we can become another species in one generation, but that we are an adaptive organism. Some folks talk about evolution in the same terms as fate. While this is correct (insofar as it is our fate to be human with specific attributes which are the result of evolution), it is much less important that what we can change and how we can leverage what we have into achievement.

Fonts, Typeface, and Typography -- what a mess. Not only does one have to repeat, essentially, the history of typography and letterpress printing to understand all this, but most fonts, like software, are protected and licensed in strange ways, which can increase risk.
And so, we turn to Open Source and Open Content licensing as well as interesting, beautiful and most of all useful typefaces to use these days.
Note that this page is updated on occasion.
There is not only special glyphs kerning (spacing) between specific sets of glyphs (e.g., x and each rounded glyph (a,c,d,e, etc.)), and ligatures, which are essentially unique hybrid glyphs representing two or my glyphs positioned next to each other (e.g., ff, fi, etc.).
Unicode Character Charts
Unicode specifies character charts and language blocks.
OpenType is an improvement over TrueType and can act as a wrapper around TrueType fonts, as well as extend their functionality through advanced glyph handling, as well as cross-platform compatibility.
OpenType vs. TrueType - 5 common misconceptions
While this video is useful, it does not take into account that OpenType is not a superset of TrueType and there are some features in TrueType not available in OpenType (e.g., hand-hinting), and being an older font format, there may (still) be more tools that work better with it.2
Digression into Languages, Scripts, Keyboards, Characters, Glyphs
First we start with languages, which may have one, more than one or no scripts (entirely verbal languages). Scripts consist of characters and glyphs, characters being discrete marks and glyphs being semantic. In many cases a glyph can be made up of multiple characters, and can also be modified in some way (kerning, position, etc.) based on combination.
Keyboards map keys to characters, but the specific font can have mapping tables which produce these custom glyphs when in some kind of proximity.
Fonts of Importance
The ultimate goal will be working toward a nice set of typefaces which will support various scripts and collectively be a great toolbox for the creation of most kinds of documents and publications.
Types of Typefaces
Serif: Humanist - Caslon, Linux Libertine, Linux, Biolinum, Gentium
Sans Serif: Geometric - E.g., Beteckna, Futura
Sans Serif: Grotesk - E.g., Nimbus Sans, Franklin Gothic URW, Helvetica
Sans Serif: Humanist - E.g., Gill Sans, Verdana, Open Sans, Gentium
While this appears useful, and is based on the Vox-ATypI classification, the criticism that this is outdated, that small differences separate different categories, and ultimately that these categories are unhelpful in any meaningful and practical sense.
OTF has within it a different set of categories that can be used, including:
OS2 Width Class: From Expanded to Condensed
OS2 Weight Class: Standard style from very light, thin to heavy, black
PANOSE Family: Any, No fit, Text and display, Script, Decorative, Pictoral
PANOSE Serifs: Degree and type of serif (from normal sans through a variety of options)
PANOSE Weight: Standard style from very light, thin to heavy, black
I've used a Kindle since the Kindle Keyboard (3rd gen), and since then purchased and used the DX for a while (the much larger model). On 06 September 2012 the Kindle Paperwhite was released and I registered mine on 10 September. I broke that model within six months by wedging it in a bag that had too many objects in it, but Amazon sent out a replacement free-of-charge (which included free shipping, and I live outside the United States).
