This post is cross-posted from Honeycomb’s instrumentation series). One of my favorite concepts when thinking about instrumenting a system to understand its overall performance and capacity is what I call “time utilization”. By this I mean: If you look at the behavior of a thread over some window of time, what fraction of its time is spent in each “kind” of work that it does? Let’s make this notion concrete by examining a toy example.

The Touch Bar is actually useful and I can’t believe how thin/light this laptop is. If you aren’t already a Mac user in the market for a new laptop, then this isn’t for you. If you are in the market or would like to see how I view my new computer, read on!

I finally got around to converting my avatar from a raster graphic to a vector format. I wanted to be able to animate the polygons using JavaScript and CSS. Another great advantage of a vector format is how the format lends itself to generate a PNG or JPG in any size. Massaging the SVG File Format First things first, I took the source image and ran it through the delaunay triangulation - image triangulation experiment software, experime....

On occasion developers ask us for cn1lib dependencies, e.g. allowing one cn1lib to use functionality in another cn1lib. This isn’t something we rolled into the cn1lib infrastructure because we strongly believe in simplicity. Dependency management solutions become fragile once nesting sets in and often mask over-engineering which is really dangerous for a tool that depends on small footprint. A cn1lib is really just an ant project that pac..

I’m old school and still rocking an old X220 laptop because I didn’t like the new ones . My battery life isn’t as great as I’d like it to be, but it gets worse when some “webapp” (which I’d much rather have as a native GTK+ app) causes Firefox to rev my CPU with their websocket (hi gmail!) poller. This seems to happen most often on planes or when I’m disconnected from the internet. Since it’s difficult to know which tab is the offendin..

We thought about skipping the release today and going straight for a release on the day of the code freeze but this might create a situation where a regression is missed because you didn’t have enough time with the code. This means we might have more than one update until the 16th release of 3.6 so please bear with us. We will release plugin updates with the code freeze and they should include the release candidate of 3.6 within them.

Just a couple of weeks ago I was offering tips on how to search the website in lieu of a search engine. Having gone thru the process repeatedly and trying many different approaches and off the shelf solutions we decided to build something simple of our own and we did . This is a compromise, search works on the server instead of using the fact that the site is statically generated. As a result it is far from ideal but it’s still pretty co..

Riverside Plaza Memory Sketch Every day for the past three months I have drawn some scene or event that I saw that day, purely from memory. Usually this is something I saw on the way to work, or, if I'm home that day, something I saw when out for a run or a walk somewhere in the neighborhood. Since I usually make the drawing at the end of the day, several hours will have passed by the time I get around to recording what I saw. To ....

We will release Codename One 3.6 on the 16th of January, this means we will enter code freeze on the 9th during which only critical bugs will be fixed with peer review. Since Codename One is a SaaS product release cycles aren’t as crucial for most of us but they provide a framework both for versioned builds and for us to focus on the more mundane aspects of product maintenance.

__ This is the third post in a three-part series on In-App purchase. Please check out Part I: Introduction to In-App Purchase and Part 2: Implementing Non-Renewable Subscriptions . Auto-renewable subscriptions provide, arguably, an easier path to recurring revenue than non-renewable subscriptions because all of the subscription stuff is handled by the app store. You defer almost entirely to the app store (iTunes for iOS, and Play f..

Opening a demo or sample code from GIT is relatively easy if you are an experienced Codename One developer but for a lot of newer developers for whom samples are often more crucial this can be challenging. One of our solutions was placing the demos in the Codename One new project menu but that’s probably not enough. First before we begin with the step by step guide let’s explain what is happening…

At the scale of the entire web, better tools are the only way to deliver better experiences. The
