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?
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 2880×1800.
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.
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.
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.
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.
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.
Javascript tools suck, all the sample code on the web is invariably wrong in some way, variable scoping as practiced is horrible, debugging is terrible. And I am just focused on a single browser target! I’ve spent a day chasing after some pass-by-reference and scoping problem. Grrr.
Of course when I spend a day on Objective-C problems, I am pretty convinced it is the worst tool ever with its bloviated syntax and huge masses of obsolete sample code.
And when I spend a day on python I get so cranky about crappy IDEs and crappy debuggers and crappy library documentation.
The only constant is me, probably I am doing it all wrong, regardless of the environment.
5 people in line waiting to pay at Barnes & Noble Bellevue vs 1 chatty cashier. 1 Nooklehead standing over at the Nook stand doing nothing while we are all trying to give the store money.
I finally called the store and asked whoever answered to come up front and help, they said they were busy with a customer. When it was finally my turn the clerk spent 1 minute on the script trying to get me to sign up for their loyalty card — not understanding that the last thing I want to do is buy more books here.
So many things wrong here. As a start, give the idle Nook dude a square reader and let him do check outs on the Nook. Giving him something to do, a chance for me to handle a Nook, and completing my transaction more speedily.
Did my first git push while in-flight! Awesome. Doesn’t feel dirty at all!
Resisting temptation for lame cloud computing joke.
UPDATE: not surprisingly, I am also now a member of the mile-high “broke the build” club!! Along with the mile-high “you stupid jerk, now fix it” club.
David Sobeski has a great writeup on facebook covering Microsoft’s methodical destruction of developer trust over the last 15 years:
I am relearning how to be a software developer after many years away and it is notable that, not only am I not using any Microsoft technologies or tools, nothing from Microsoft even entered the consideration set as I selected targets, libs, tools, etc.
Rehashing all the missteps is entertaining, David does a great job of that, I never tracked all this stuff and many of the acronyms and decisions around them are lost in the fog of history. For whatever reason, Microsoft is at the nadir of its developer influence.
If I was the new CEO at Microsoft, fixing this would be job 1, and I wouldn’t be timid. I would have a 6 month plan to make Microsoft relevant to every developer. And there is no way to do that without buying a bunch of assets to get out in front of the existing parades. I’d buy Github or Atlassian. Stackoverflow. I’d buy or embrace a Linux dist — CentOS maybe, or screw it, just buy RedHat. I’d jump into the vagrant/docker world and buy a position in that space. I’d buy modern leading noSQL and Hadoop distributions. Xamarin as a tool. And 10 more things. At the end of this, Microsoft would be in the conversation with every developer on the planet. OK it would be a chocolate mess of technology assets, but read David’s write up — Microsoft has a chocolate mess of assets now, without any developer relevance.
I wouldn’t worry at all in the first 3 years about cleaning all this up and rationalizing it. I’d run the teams separately, I’d encourage them all to go go go, and I’d create organic opportunities for them to talk and discuss collaboration, without forcing it. Relevance as measured by developer use, and speed of evolution would be my top criteria. Every developer who is not using a Microsoft tool or runtime would be viewed as a failure. Internally I’d direct the Visual Studio team to become the tool for every developer, regardless of what platform they are targeting — iOS, Android, AWS, whatever. Rationalization could come later if at all.
This strategy will create confusion, overlaps, duplications, conflicts, and chaos — but dammit, Microsoft will be relevant again. Relevance will make up for a lot of sins.
We always go on a bit of a board game binge over the holidays. We played some holdovers from past years — Settlers of Catan, Seven Wonders. I got an awesome bamboo catanboard for Catan, that was a great gift. And we got the Cities and Leaders expansions which added additional layers to this game. 7 wonders is a typical resource accumulate, barter, and build game, with a ton of strategic options.
And then we tried a bunch of new games, the ones that passed the bar:
We had some failures too but I won’t dwell on those…hope your holidays were good!
UPS facilities must be absolute zoos at this time of year. The status for one of our packages below. Here’s hoping it doesn’t loop again at Redmond.
From Twitter, apparently Bud Light is the 2nd most popular search on Google for a beer brand:
Most searched beer brands on Google in the US in 2013: 1. Blue Moon, 2. Bud Light, 3. Bud Light Platinum, 4. Kingfisher

I’m scratching my head, what exactly do people need to find out about Bud Light? I have nothing against Bud Light. It is ubiquitously available and ubiquitously advertised. Certainly people aren’t having problems finding the product at Retail. Certainly there is no mystery about what it is. I just can’t figure out what people are thinking when they decide to turn to Google to learn more about Bud Light.
Playing with shadertoy, threejs, kineticjs, chrome experiments. I can feel my macbook heat up and i can watch the battery drain! Pretty stunning what you can do with webgl.
I am trying to figure out the best practice for integrating webgl with a webpage, in particular text. Overlay of CSS/HTML on a webgl element? Stuffing the text right into the webgl? Does the next version of webgl change anything? What lib to use on top of wegbl to make this easier?
Historical aside — what a huge missed opportunity for Microsoft, read for instance Alex St John’s story of the early days of really expressive content on the web. Microsoft had a browser code-named Chrome in the 90s that had the idea of webgl built into it. Sadly internal machinations killed it — political infighting about ownership of graphics leadership within the company, and a lack of vision in senior management — not enough people were excited about the idea of a browser and web content that brought a PC to its knees, failing to understand that thanks to Moore’s Law, this problem would go away within a short time.
