I find it fervently infuriating when someone uses the word passion and degrades it. They degrade the meaning of the word. Passion is the ultimate upgrade of the hobby, a cultivated curiosity. Something you're currently dedicating your life to. You diminish it when blurting that a person that doesn't spend any time outside the "obligatory work hours" on his passion, not even a thought, to be passionate. What is passion if it's not thinking a..

At Cerner, we love Ruby and Rails and use it prominently in our cloud based solutions. When we found out RailsConf 2016 was going to be held in the hometown of Cerner’s headquarters in Kansas City, Missouri, we were excited for the opportunity to support the conference by attending as well as being a sponsor and hosting one of the official after parties. RailsConf 2016 took place in the heart of downtown Kansas City.

This is the story of my involvement with Fine Uploader, how it changed my life, how it affected those around me and my peers at Widen, and how I hope it can continue to have a positive net effect on the open source community and individual developers.

Last week, over 72 companies demonstrated their approaches at Finovate Spring 2016. As VC funding slows down, entrepreneurs and intrapreneurs are now focused on incremental improvements instead of transformational game-changers. What's next for fintech?

It’s been quite a busy week with many changes and updates, some of those were in line for a couple of tools we plan to introduce over the next few weeks. This week I also placed an interesting thread from the discussion group. Normally I try to keep this focused on stackoverflow but if a good thread comes up in the discussion group that raises an interesting topic I think this is a good place for it too.

Today I turn 31. Before the day is through, I'll have ended up celebrating with family and coworkers. And Bash, because as it turns out, Bash can be a bit festive. I find most default Bash prompts to be rather boring. Sure, they vary from platform to platform, but they all seem a little too lite on info that I care about. A few years ago I decided to liven it up a bit.

Agile Data Warehousing and Business Intelligence in Action

Very often the construction of a Data Warehousing / Business Intelligence (DW / BI) system is performed following the flow of traditional engineering: analysis, design, construction, testing and implementation. Communication between developers and people interested in the business is almost nonexistent, and developers are interested in technologies for working with data but often neglect to ask this most important question: "What business q..

We’re all pretty jaded when it comes to software but when I first saw yHomework I was completely floored by it! Where was this tool when I was in junior high? If you haven’t seen yHomework in action I suggest you give it a try right now on your Android or iOS device . In a nutshell the app accepts several types of math equations starting with the basic algebra e.g 3(x+5)=6 and then shows you the process of solving it as if ..

In high school I did well in math competitions and even qualified for the national team. Part of the reason was that I spend a bunch of time on my own solving math problems. It didn’t feel like a compulsory work. Instead, it was often a compulsive behavior for me. I was often unable to un-glue myself from the math problem at hand. When I saw a good problem, I attempted to solve it. The easier ones I could solve quickly. But some of them....

One of the often requested features in Codename One is zip support, we had some issues with it until a couple of years back when we added tar and gzip support. But people still asked for standard zip file support which was missing. We’re working on a tool that we hope to share next week that needs zip to work. Initially we thought about doing this natively as zip works on most native OS’s but one of the true benefits of the tool is ..

I’m just going to jump right into the definitions and rigor, so if you haven’t read the previous post motivating the singular value decomposition, go back and do that first. This post will be theorem, proof, algorithm, data. The data set we test on is a thousand-story CNN news data set. All of the data, code, and examples used in this post is in a github repository, as usual. We start with the best-approximating $ k$-dimensional linear subs..

Some of the wifi routers (especially beetel models) provided by airtel broadband is paired with two SSIDs(Access point), One is an actual SSID for internet access and another one called MGMNT, which is used by airtel for maintenance / automatic configuration. The default key for MGMNT is 0987654321, which is hard-coded into the router’s firmware and the stupidest part is there is no option to disable it. Now lets start hacking!, Con....

We're not seeing the banks or the airlines, or the bigger retail outfits open-sourcing various bits of software. Why not? I think that the key distinction is, ‘Is this company one where the engineering staff or technical staff has a lot of leverage within the organization?’" —Martin Fowler, Chief Scientist One of the themes highlighted in the April 2016 edition of the Thoughtworks Technology Radar was “Open Source as a Virtuous Byproduct.”

When we initially launched Codename One it was pretty hard to imagine today’s apps. Menus and back navigation were miles apart when comparing Android 2.x and iOS 4.x… So we created a very elaborate set of abstractions (command behavior) that served as a set of patch framework we could live with for a while. But like any patch framework this started crumbling under its sheer weight and this lead us to the Toolbar API . The reason w..

This week we chose to modernize the very outdated Chrome Demo . This demo is one of our early demos developed during the iOS 4.x era. We licensed its original design from app design vault and created a Codename One version of that original template. While the guys in app design vault modernized most of their templates to iOS 7 flat design they didn’t do this for the Chrome demo.

We talked about the new Android 6 (Marshmallow) permissions in Codename One last week and so far we’ve been pretty happy with the result. We had some build regressions on the older Ant based build path but those were fixed shortly after and it’s been smooth sailing since then. As part of the transition to the new permissions system we added two features to the simulator and the AndroidNativeUtil class.

I was just getting in my terminal when I noticed that the cursor was not blinking. C’moon! I can work with a non-blinking cursor. When a cursor blinks it sets up the pace. I keep moving as the cursor blinks. It is hypnotizing. I can leave my thoughts behind and operate in a state of flow. The blinking cursor is easy to see. I don’t need to look for the white rectangle. I can spot it much easier even when I’m not focused on the screen. I....

Introduction If you are new to Linux or the Mac you might find installing Go to be a bit confusing. It was for me when I started learning Go. Go was the reason I stopped using Windows, which I used for 20 years. Even if you’re experienced with these operation systems, setting up Go might seem a bit of a mystery. With this in mind, let’s walk through installing Go.

Why Inclusivity, Equity and Leadership are key. Recently, I found an annual report from my first employer, a large UK firm, where I was one of six graduate trainees, with five of us being women. At that stage in my life, I didn’t even think about equality and diversity, and assumed the notion of 'work hard and you will be rewarded whatever your gender', would be upheld.

Previously on Anvil: version 0.1 was the first one to use incremental rendering approach instead of virtual tree diff’ing. Version 0.2 added support for XML layouts and binding data to existing views. Version 0.3 was about two-way data bindings - most views got simplified lambas for handling user input and many related bugs have been fixed. Today’s version 0.4 takes care of support libraries. I personally rarely use support libraries (at wo..

Last time around we compared Codename One to QT and this time around I’d like to compare Codename One to the 800 pound gorilla: Xamarin. Xamarin is an amazing product that I contrasted with Codename One in the past but this is worth repeating. On its surface Xamarin might seem like a similar tool to Codename One using C# used instead of Java, but this is misleading as the tools are so different conceptually they have very litt..

Looking at a list of unanswered questions people have sent me, I couldn’t find a single reasonable thread that united any of them, save the fact that they all concern my truckly ways. They’re all pretty much orthogonal in the N-dimensional space that truck questions occupy. Let’s get to them. What does your family think of your living situation?
