Firebase is the base behind YAC’s many functionalities, remote config is one of them. In this post I have described how remote config solves some of the problems I have.

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..

I now have a scraper that works and a static website built with Hugo. Putting these together, I need to re-deploy the static website each day with updated inventory, which the scraper provides. So my single VPS instance will run a daily cronjob script that: scrapes the inventory. stores it in the database. git pulls the website from Gitlab. pulls updated inventory from database. inserts updated inventory into website. pushes web..

Git Deployment Tutorial SSH Key Setup Context I needed to push to deploy my scraping app to a server. Using git seems to be the way to deploy web apps, so thought to use the same method. Locations ¶ There are four locations to keep in mind. I’m deploying to an Ubuntu Server 16.04. A. Local Git and Working Repo : /Users/dhruvkar/projects/projectname/ B. Remote Git Repo : /home/gitrepos/projectname.git/ C. Remote Working Repo ..

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.

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....

This node app generates random json maps compatible with Tiled and Phaser.js. It uses a cellular automata algorithm to generate the background and then randomly places objects on the map. First set a birth and death rate as well as various spritesheet tiles for your background and objects then run app.js. The json output can […]

Since moving to Jekyll last year, I’ve done relatively little to tweak the inner workings of this site. After all, one of the most appealing things about having a static site is that it doesn’t need to have a lot of moving parts. It just works. But today I finally got around to a couple of housekeeping items that have been on my list: image captions and MathJax. Image captions For image captions, I settled on a beautifully simple so....

Apache Flink has hit version 1.3 lately and the SQL support has been extended. You can find what is supported from the docs. In this blog post, I will be giving a small example for using Streming SQL a Tumbling Window. Consider you are streaming room temperatures that are being read from many sensors. You want to find the average tempetarute in windows of 10 seconds and act upon it. You want to do it in SQL.

This year Postgres open and PGConf SV have combined to great a bigger and better conference right in downtown San Francisco. I’m obviously biased as I’m one of the co-chairs, and I know every conference organizer says picking the talks was hard, but I’m especially excited for the line-up this year . The hard part for me is going to be which talks do I miss out on because I’m sitting in the other session that’s ongoing. You can see the full....

1300 words, 4 and a half minutes. This will probably be the first and last time I write about social networking. I’m an antisocial social networker. I had an expectation that part of the job of a networking platform (professional or social) would be to filter content or updates, both in terms of who was posting them and the individual significance or quality of the posts. Boy was I wrong. One person re-posts every single article they see, a..

Running Cucumber scenarios in parallel can be tricky, especially when a custom test runner is used. That's why we created Cucable - a Maven plugin to split test scenarios into smaller chunks that can be run at the same time.
