We were prepared for an uphill effort in terms of getting Kotlin up and running… Turns out that getting the basic support out of the door was much easier than expected with a few expected caveats that will hopefully be acceptable moving forward. Steve did pretty much all of the work on this, I asked him to write a post where he explains the challenges as this isn’t the first time he ported a JVM language to Codename One.

systemd : it's the init system that (some?) love to hate. Full disclosure: I find systemd a little overbearing, although by no means would consider myself militantly anti-systemd. It has obvious advantages, and although I'm at philosophical odds with it at some levels, I see no reason why everybody shouldn't understand it a bit better - especially now that most people will need to deal with it on their favorite distros. This post....

On occasion I answer a question on stackoverflow, the discussion forum or elsewhere and I get a response of the form of: “this wasn’t clear from the docs”. We improved the docs but befitting a huge project run by engineers without a technical writer in sight this is a bit of a problem… The thing is that this is a problem you can fix regardless of your level in engineering or in English.

This past week a tsuru user was having a problem in one of his apps. Some units of his app would simply get stuck, timing out every request and apparently doing nothing. As a workaround he wanted to kill the problematic unit and force it to restart. On tsuru you are able to restart all units of an app but may not choose a particular unit to restart. We then “sshed” into the problematic container, by using tsuru app shell -a

What do we see here? On the left is a papier-mâché box, with a Palekh style miniature on it. It is dated 1961. The style developed after icon painters from the city of Palekh had to find new jobs following the revolution of 1917. The painting on the box depicts the tree stumps on which Vladimir Ilich Lenin used to rest and work. In the distance a foreign delegation looks on. On the right, Fidel Castro is laying flowers to the tree stumps,..

Last October, I had the privilege to speak at Grace Hopper, the world’s largest gathering of women technologists. It was impressive to see 15,000 fellow female technologists gather together to share their experiences and technical expertise. To look into the audience, and see a room full of other female engineers was a great experience! My talk was titled, You May Not Be a Polyglot, but Your Code Needs to Be (previously presented at Midwest..

The really awesome book don’t go bad if you know what happens. That’s because they are intricate enough that there is still a lot to be experienced on a second, third and fourth read. Just like poetry, great prose keeps on giving the more you read it. And great movies keep on giving the more you watch them. I recently re-read Hemingway’s “The old man and the sea.” I already knew what happens. Let me “spoil” it for you. An old fisherman ....

Our first [right-to-left platform](https://www.trivago.co.il/) was released in 2014. We had developed a solution to generate right-to-left CSS with Sass mixins and variables as we have [described](https://tech.trivago.com/2015/04/27/right-to-left/) in a blog article. We used this approach for nearly 3 years but recently migrated the right-to-left CSS generation from pre-processing to post-processing with [RTLCSS](http://rtlcss.com/). With t..

This is a follow-up to the ROS prototype to production on Ubuntu Core series to answer a question I received: “What if I want to make an image for the factory, but don’t want to make my snaps public?” This question is of course not robotics-specific, and neither is its answer. In this post we’ll cover two ways to do this. Before we start, you’ll need a little bit of an Ubuntu Core imaging background.

Push gets a lot of support queries, it’s a hard subject to wrap your head around especially with all of the conflicting and shifting landscape around it. To make matters worse every OS conceptualizes it very differently. I go into some of the really advanced stuff such as fallback behavior in the advanced course but basic stuff is still a crucial first step. So I adapted some of the material from there and re-did the push How Do I? vid..

It's not uncommon to hear, from persons that relocated to a new country, discussions related to the dissatisfactions with the new land they've set upon or the land they've just left behind. Apart from the stifling reply, "they're just not used to it", what else is hiding behind this phenomenon. Let's dissect this case.

If you have been following my previous posts on Rust’s drop order, you may want to know how it all ended. In january, I summarized my research in an RFC and submitted it for consideration of the Rust community. Today, after six months of discussion (with around 80 replies), it has been finally accepted as RFC 1857! Besides reading the RFC itself, you may want to check my previous posts to see the reasoning that led to it:

If you’re a mobile app developer, at some point in time you’re going to need to interact with a backend. One of the tasks you might need to do is to retrieve and display images from a server, or submit an image to that server. What format should the image be in when you’re submitting it? How do you convert bytes received from a service call into an image? Let’s build the entire stack from the server to an iOS App to find out how. Setting....

However, recently, I've had the privilege of working on the development of a privacy-preserving email client called Pixelated, which seeks not only to decentralize control of data, but also to make privacy accessible to the non tech-savvy user through a modern email interf..
