Ten years ago we moved to Lebanon. There was a culture clash. In this post I'll explain why some locals go on destructive paths. We all know generalizations have the nasty effect of activating justice warriors. My intention is not to trigger rage, generalizations are what they are, a resonance of the state of mind *we* are living in. While everyone is not going to read this post and take value out of it I still wish for it to be a wake ..

I have a GNU/Linux server which I mount a few LUKS encrypted drives on. I only ever interact with the server over SSH, and I never want to keep the LUKS credentials on the remote server. I don’t have anything especially sensitive on the drives, but I think it’s a good security practice to encrypt it all , if only to add noise into the system and for solidarity with those who harbour much more sensitive data.

Today we are going into code freeze for Codename One 3.4 which is due one week from now, because of the fast release cycle we don’t need more than a week of code freeze to stabilize our current release. The code freeze applies only to the Codename One libraries and ports as those are the parts that will be inherent to the release. How does the Code Freeze Work? The pieces of Codename One that are frozen are effectively the entire gi..

With the latest version of the Android port we fixed a long running bug in gradient drawing on Android. Gradients should now work correctly and will also be performant potentially even faster than images on Android. Our standing recommendation is to avoid gradients as they pose a memory/performance penalty on most platforms and so this change raises the question of using gradients back into the forefront. We gave this some..

It might be good to feel bored. The bored mind is seeking. Now, there is a difference between bored and distracted. The distracted mind feels overwhelmed. When I am distracted, there are too many stimuli. I might get distracted by my phone or think about the movie I watched last night. Being distracted means that I’ve surrendered control of my thoughts to external prompts. I might have decided to dedicate my time to certain activity, but....

The jat app is very similar to whatsapp in some regards but is more oriented towards group communication than SMS replacement. Over the past couple of weeks we picked it up as a great communication tool in our team. It uses push notifications to notify and activates accounts via SMS. This makes it very convenient for someone like myself who moves between devices constantly. Chat is a very common use case for developers in the Codena..

EDIT : This article was first posted in 2016. As of 2019 I still have to use Windows at work, but now I just use WSL with wsltty. At work I have to use Windows as operating system on my workstation, even though I manage almost only linux servers. There are dozens of ways to connect from Windows via SSH to a linux server and I will tell you my way. I started (of course) with PuTTY , the unarguably most famous ssh client for window....

D3 is great at data visualizations, but it manipulates the DOM directly to display that data. Rendering DOM elements is where React shines. It uses a virtual representation of the DOM (virtual DOM) and a super performant diffing algorithm in order to determine the fastest way to update the DOM. We want to leverage React’s highly efficient, declarative, and reusable components with D3’s data utility functions. At this point, we can safely....

It turns out that we just fixed that specific issue as we are moving into the final stretch before..

Plenty of people are talking about how organisations should capitalise on design, yet few are talking about the practicalities of what it looks like to actually deliver it. Pairing developers and designers removes the natural suspicion between them, is fun, easy, and presents value to customers faster, making businesses—and teams—happier.

As part of our continuing effort to squash bugs for the 3.4 release date we hit two major issues, the first of which is a long time RFE to fix PDF viewing on iOS & Android to work consistently . This also applies to any file opening in iOS/Android which should now be trivial with the Display.execute method. Just use that method on any file within your home directory in FileSystemStorage and it should launch the native app to view..

Lately I've been exploring the world of Clojure. I'm not sure whether it was the siren song of functional programming that started driving me, the simplicity of Lisp, or my curiosity about this language that was being promoted by the likes of Uncle Bob. Whatever the cause, I needed to explore this strange world head first. I needed to try out this language for myself. I spent much of time just dipping my toes in and writing little toy progr..

Have you registered for a new user account in an app before? How about adding your payment info for buying something online? Those are two examples of what a “workflow” can be. Workflows are usually associated with a set of screens that appear in different orders depending on what the user selects. For example, registering with Facebook vs. email can change the sequence and number of screens presented to the user. We will demonstrate how st....

As part of the bug fixes for the 3.4 release we fixed issue #1725 which was surprisingly difficult to fix… As part of that fix we also added a new method to TextArea by the name of setActAsLabel which we now implicitly call in the SpanLabel & SpanButton classes. So why do we need that and why not just use the text area as it is? There are two basic challenges in multiline strings, the first is related to the way layout managers w..

The singular value decomposition (SVD) of a matrix is a fundamental tool in computer science, data analysis, and statistics. It’s used for all kinds of applications from regression to prediction, to finding approximate solutions to optimization problems. In this series of two posts we’ll motivate, define, compute, and use the singular value decomposition to analyze some data. (Jump to the second post) I want to spend the first post entirely..

ShipIt Day is an all day, all night hackathon with the goal of building something awesome, usable, and value-adding within the given 24 hours. This Spring marked our fifth ShipIt Day, with participation and reach growing with each event. We kicked off the event at 10 AM on Thursday, when teams broke out and got to work and stopped only for food and caffeine. Many stayed until a few hours after dinner arrived, several stayed all night and to..

One of the things we are often asked to do at Thoughtworks is help organizations and teams transition to new ways of working and thinking about work. Frequently, these requests are driven by an organization’s desire to compete more effectively in their marketplace, or to protect themselves against disruptive newcomers. Often beginning with the Information Technology (IT) function or department, they have specific goals in mind, such as adop..

As I mentioned last week we are redoing a lot of our videos and this video will serve as a benchmark to where we want to be in terms of production. We just released a modified version of the video geared towards IntelliJ/IDEA users here . We are really excited about the new IntelliJ/IDEA plugin we released a couple of weeks ago and this video shows off some of its capabilities.

One of the hard things to debug in Codename One is UIID/Padding/Margin placement which is often tricky to get “just right”. I use the Component Inspector quite a lot to review a layout that misbehaves and gain further insight into what’s happening in runtime. __ | You can gain insight into the Codename One component hierarchy by running the simulator and selecting the Simulate → Component Inspector menu option. This will present..

This post is less about the “trucks” and more about the “tax-advantaged accounts”, which hopefully won’t offend too many sensibilities. I just figured it’s been a while since I last forayed in my financials , and the several ensuing months have seen some modifications to the plan. The biggest of these modifications is that I added a new tool to my early retirement arsenal: the Mega Backdoor Roth . The Mega Backdoor what?

This is the first set mixed in nearly 12 years. Working in an open office space means many hours of my day are spent listening to music with headphones on, cranking away at software code. For me, this means listening to music that doesn’t distract from the task of writing and problem solving. This set was designed in the spirit of musicForProgramming.net . This set was heavily inspired by sci-fi movies that use long scenes to showcase ....

When we first started to present Codename One to investors a very prominent local investor said he’d commit to a round of funding if we allow Android developers to import native Android apps to Codename One. We passed on that which in retrospect might have been a mistake but the technical challenges were the main reason for that decision. Should we Support Android Native Code? Ignoring the technical issues involved this might seem l..
