Bluetooth is one of those specs that makes me take a step back… It’s nuanced, complex and multi-layered. That isn’t necessarily bad, it solves a remarkably hard problem. Unfortunately when people say the words “bluetooth support” it’s rare to find two people who actually mean the same thing! So while we did have a lot of requests for bluetooth support over the years most of them were too vague and when we tried to follow thru we us..

In karate practice we train by performing a predefined sequences of actions, called “kata”. These include blocks, strikes, stances and jumps in a strictly defined sequence. Throughout the kata, every body part has an exact purpose. The legs do stances and kicks. The arms and forearms - blocks an punches. Even the smallest parts of the body have a part. The eyes need to look in the direction of the technique, the feet need to “grab” the fl....

Editor note: CocoaPods remains supported, but current iOS dependency guidance now also covers Swift Package Manager (SPM) and mixed CocoaPods/SPM setups. See the current “Working with iOS” section in the developer guide. CocoaPods is a dependency manager for Swift and Objective-C Cocoa projects. It has over eighteen thousand libraries and can help you scale your projects elegantly. Cocoapods can be used in your Codename One project..

Our identity defines the choices we make. Our actions become our identity.

When we face choice and say “Yes, I will do that. I am that kind of person,” we use our identity to justify our choice of action. The choice might not be the most convenient, but it matches our preconception of who we are. When we decide whether to make our bed in the morning, whether to drive above the speed limit, whether to drink coffee or take a nap when tired, our identity has a say in the decision. If we consider ourselves tidy, we’....

Woke up this morning to the amazing news of Google winning against Oracle on the issue of fair use! This is great news for everyone as it effectively makes “clean room implementation” legal. This solidifies Java’s status as “open” showing that even its owner has limitations on their power. I might write more about this next week if I have some time, I just hope the verdict doesn’t get turned in an appeal.

Properly used, user research will destroy your product. This is a feature, not a bug. You have an idea, maybe even a great one. You’ve done your design sprint, your visioning session, your intense few days of white-boarding. You’ve built your draft roadmap, have a few personas and a well-worn copy of the Lean Startup. No plan, though, survives its first contact with the enemy.

Starting with the new version of the NetBeans plugin we will have the new settings/preferences UI which we introduced in the IntelliJ/IDEA plugin . Currently this will be in addition to the main preferences but as we move forward we will only add features to the new settings UI. You will be able to open the new project preferences UI by right clicking the project and selecting it in the Codename One section:

Born for it: How the Image of Software Developers Came About

The stereotype of the socially-awkward, white, male programmer has been around for a long time. Where does this image come from? Did the demographics of the world’s programmer population really evolve naturally, because “boys just like computers more”? What shaped our perception of programmers? This text is about some possible explanations I found when reading about the history of computing.

We were stuck on an “old” version of xcode in the build servers. This hasn’t been a big deal for most features but in some cases we are running into issues e.g. in using the full capabilities of the new iPad or 3d touch. The reason for this is Apple’s backwards compatibility policy. Apple allows you to run an older version of xcode, but the newer versions of xcode always require the latest version of Mac OS X. The problem here is th..

ppx_core: context-free rewriters for better semantics and faster compilation

At Jane Street, we have always been heavy users of pre-processors, first with camlp4 and now ppx. Pre-processing makes the infrastructure a bit more complex, but it save us a lot of time by taking care of a lot of tedious boilerplate code and in some case makes the code a bit prettier.

PropertyCross is one of our newer demos, due to that there was relatively very little work needed to modernize it and this resulted in a stunning improvement over the existing demo. During that process we also discovered a small regression due to changes in the web service we relied on. Check the live version running on the right hand side thanks to the power of the Codename One JavaScript port!

Sticky headers was one of the first big requests we said no to. Back in the day a lot of people asked for it but we always shot it down because it was too hard to implement on top of our Swing inspired lists. This predated our Container improvement, InfiniteContainer and InfiniteScrollAdapter . While our preference for lists has waned we never got around to show how easy it is to do sticky headers with Container until last week..

Me: Why is this report different to the one in production? SysAdmin: Dunno. I guess they must have fixed it production and forgot to check it back into source control. If I had a dollar for every time I’ve had that conversation I’d be a rich man. It is usually the result of some late-night troubleshooting and finally the system is working as expected and everyone goes to bed. But the next day, nobody remembers what exactly they changed..

One of our support emails drew my attention to a glaring omission in our icon font support… When we create an icon for a Button it’s color matches the unselected color of the button which might not look as attractive when the Button is selected or pressed! The thing is that with an icon font this is trivial to accomplish and requires literally no code changes. So starting with the next update calling FontImage.setMaterialIcon(La..
