Been quiet on the blog. Super busy learning about modern software development. In no particular order, I’ve been playing with: webgl, three.js, node.js, shaders, opencv, 0mq, travis ci, ansible, raspberry pi, arduino, resin.io, docker, vagrant, coreos, objective-c, github, hadoop, ubuntu and debian and raspbian and fedora and centos and RHEL, and about 100 more things. Having a blast!

We are looking to hire a few people and if any of the mishmash above appeals, let me know…

One milestone of my new career direction is my first accepted pull request to an open source project (the node.js mappings for opencv). Ok it was a silly little bit of frippery, adding line thickness to some line drawing routines, about 4 lines of code, but it has been a long long time since I contributed any code to any effort so it makes me kind of happy.

I have a more sizeable contribution chunked up and ready to go soon, so hopefully this won’t be the last.

I am just one of the crowd per geekwire

I bought a Lytro back in the day. It spent a week in my bag before it hit the technology graveyard in the corner of my office.

My narrative clip lasted maybe a week. Everyone around me was freaked out. And mostly I just ended up with a lot of pictures of the edge of my desk.

I just got my Pixy. Maybe I am doing it wrong but this thing doesn’t seem to detect squat. Maybe it works great in some super controlled setting but not worth my time.

Of course I had to order a Centr.

I am eternally optimistic. One of these things is going to be useful.

• OpenGL Programming Guide by Shreiner, Sellers, Kessenich, Licea-Kane. Incredibly boring in a good way. Very useful depth walkthru of OpenGL.
• Forty Signs of Rain by Kim Stanley Robinson. Boring in a bad way, unreadable. The author attempts to wrap his nonfiction treatise with some thin and dull characters who lead boring lives. Gave up on.
• Riddle-Master by Patricia A McKillip. Fun semi-classic fantasy romp. Nicely wraps up in a modest number of pages unlike the modern commercial 10+ tome series.
• Grammar of the Film Language by Daniel Arijon. Great reference on a topic I was clueless about, hat tip to Paul. A little dated but super useful.
• Revolution in the Head by Ian MacDonald. Another excellent history of the Beatles, focusing on their songs and what was going on in the culture and the group at the time. MacDonald takes a very critical look at the songs at times, which makes the discussion all that much more compelling.
• Lexicon by Max Barry. Fun adventure with very erudite zombies.
• Mind of Winter by Laura Kasischke. Uber-creepy story of a woman in the grips of a possible breakdown, or is something else going on?
• Missing You by Harlan Coben. Another solid Coben, started out a little slow, but grabbed by the end.
• Annihilation by Jeff VanderMeer. At first I thought this was going to be yet another post-apocalyptic dystopian series written to sell books, but this is something quite different. An expedition enters a blighted area in the south, and nothing is what it seems – the nature of the blight, the goals of the expedition, the members of the expedition all have hidden natures. I’ve pre-ordered the next book.
• Duke of Deception by Geoffrey Wolff. A man unravels the life of his father – a conman, liar, thief, but still a loving father. Complex relationship.

Just a reminder to self – some of the kits out there come with <1 amp supplies, and most come with 1 amp. The 1 amp supply is barely adequate for the base rpi plus camera. Less than 1 amp and camera use will drop your internet connection.

Now if you add in a USB wifi dongle, 1 amp no longer is sufficient. I am having to use a powered hub.

I’d suggest a 2 amp minimum supply.

I am hosting the webview controller in an OSX app. I have followed the code sample in calljs and i can successfully call javascript functions inside script tags from objective-c. This integration requires that the objective-c program know the name of the javascript function. for instance i have a javascript function called “objective_c_entry()”, and in my objective c wrapper, i can call that entry point using:

NSString *callResult = [[webView windowScriptObject] callWebScriptMethod:@"objective_c_entry" withArguments:args];

Now I want to move all my javascript into require.js modules; i am not clear how to reference a function in a require.js module from within objective-c. if i am moving my “objective_c_entry” function into a require.js module named “integration”, what string do I pass to callWebScriptMethod?

• Tune In by Mark Lewisohn. Fascinating telling of the Beatles’ early years. Massive detail. Uplifting in many many ways, the group overcame great odds, while staying true to themselves. But never let your kids catch you admiring this book, the young Beatles were not exactly role models.
• All The Songs by Jean-Michel Guesdon and Philippe Margotin. Exhaustive notes on the writing and recording of every Beatles’ song, which provides an interesting window onto the arc of the group.

http://noncombatant.org/2014/03/03/downloading-software-safely-is-nearly-impossible/ – and this only scratches the surface. Of all the reasons why I don’t use a Windows machine for development, this is the stupidest, and simplest to fix. Just ship a reasonable ssh client, it is not that hard.

Quite an achievement – Dendritic Inhibition in the Hippocampus Supports Fear Learning – and won’t be his last. I am jealous, I have aspired to go down the research path at many different points in my life but it has never worked out. Huge congrats!

So I have a little app that hosts the Webview control and doesn’t do a whole lot more. I am running it on a MacBook Pro Retina display. I’ve enabled fullscreen display, I’ve set the window in the xib to be full retina 2880x1800.

But the webview seems to think it is running at 1440x790ish or so. Basically half res. As reported by NSScreen. And it is pretty clearly running at half resolution.

The same web page looks fine in Chrome, full retina resolution.

Ah interestingly, in Safari, it is also running at half resolution. Hmmm.

Nothing obvious on StackOverflow. Nothing obvious in Apple developer doc (tho I certainly probably missed something).

UPDATE: Mr. Sobeski gave me some ideas. The retina devicePixelRatio is probably involved. Apparently this creates some problems in some configs. http://stackoverflow.com/questions/4405710/uiwebview-w-html5-canvas-retina-display might be a direction to try.

• Parasite by Mira Grant. The start of a new series by the author of the Feed series, which I found to be among the best of the zombie novels I read. This is also a lot of fun, a twist on zombies, in some way much creepier. Looking forward to rest of series.
• The Ice Harvest by Scott Phillips. A Fargo-esque spiral of crime and misdeeds. Fun.
• Harvest by Jim Crace. Crace does not write happy tales. This story details the collapse of an insular farming village in the face of political and economic change, and how one man in the village experiences the changes. Kind of grabbed me tho it is a mostly depressing little tale.
• We Are All Completely Beside Ourselves by Karen Joy Fowler. Gripping. A woman tells the story of the unusual family tragedy that occurred at age 5, and how that has rippled through her life and her family’s life. Very hard to put down, and the messages will sit with me a long time.
• Mr. Peanut by Adam Ross. Three intertwined marriages beset by problems and power struggles, with some Hitchcockian murder built in, or maybe not, and with a mix of fiction and maybe truth. A lot going on here. And a lot of pain. Not sure how I feel about.
• Possession by A.S. Byatt. Snore. I need to remember that Man-Booker Prize != interesting.
• The Rector of Justin by Louis Auchincloss. A charismatic school founder and his impact on all the lives of the people around him, both good and bad. The power and charisma of a founder/leader can lift some people up and drown others. Really excellent tale and relevant in many walks of life.

I didn’t really want to, I don’t use LinkedIn much, but we are hiring a couple people for the stealth startup I am working on, and I am starting to see traffic to my profile that might be related to job search. And so I am starting to think my profile should look better (thought I haven’t done a thing about), and I considered paying for a higher grade of LinkedIn service so that I could see who was pinging me. But, wow, $240 a year for LinkedIn business service?? That explains their lofty valuation I guess. That is a very rich price to expect of every business professional, the marginal cost to provide the service is effectively $0. I’d worry that this price will drive substitution, it is certainly making me think about that. I need to get a lot more for my $240 than they are offering.

Who else gets $240 a year from business professionals for a software/communications service? When a corporation rolls this up for all their sales and marketing people, how are they going to feel about it? I am sure there is a corporate discount plan tho.

Bigotry, poverty, abuse, healthcare, education, government waste and incompetence – I could go on, these are big issues in our society, and I can get outraged about them and have occasionally done so. There are certainly other issues in this category.

Whether or not a certain kind of taxi service can operate in a certain way, or whether or not cars can be sold in a certain fashion at a certain location? Yawn.

Over the holidays I had to create an Ultraviolet account. I was trying to watch a movie on our new XBOX One and I could only find it on the Vudu provider, and so first I had to create a Vudu account, and then that chained into having to create an Ultraviolet account. No idea why all this fuss was required, and I didn’t really know what Ultraviolet was for, but we got to watch our movie.

Now one month in, I get a piece of marketing spam from Ultraviolet, and now it is all clear:

Imagine … the freedom to access your movies and TV shows through many retailers

Wow. Mind blown. What a world that would be. I am so thrilled and excited. It sounds so much better than the 20 other legal or not-so-legal ways to watch videos. And I am so glad that retailers are fully involved, that sounds like it is going to be so much better for me.
