LinuxCon China 2017: Trip Report

Linux Foundation held a combination of three events in China as part of their foray into Asia early this year. It was a big move for them since this was supposed to be the first time Linux Foundation would hold an event in Asia. I was invited to present a talk on Hardening IoT endpoints. The event was held in Beijing, and since I have never been to Beijing before I was pretty excited for the talk. However, it turned out the journey is pretty long and expensive. Much more than a student like me can hope to bear. Normally I represent Mozilla in such situations, but the topic of the talk was too much into security and not aligned much with the goals of Mozilla at that moment. Fortunately, Linux Foundation gave me a Scholarship to come and speak at LinuxCon China which enabled me to attend LinuxCon and the awesome team at Mozilla TechSpeakers including Michael Ellis and Havi helped me get ready for the talk.

The event was held at China National Convention Center. It's a beautiful and …

Linux Foundation Open Networking Summit

The Open Networking Summit took place on April 3-6 – where Enterprise, Cloud and Service Providers gathered in Santa Clara, California to share insights, highlight innovation and discuss the future of open source networking. I was invited to give a talk about Web Virtual Reality and aframe at it. So, Open Networking Summit (ONS) actually consists of two events – there might be more, but I was involved with two. ONS is the big event itself. There is also the Symposium on SDN Research (SOSR). This is an academic conference that accepts papers.  There were some pretty fantastic papers at the conference. My favorite one – there was a system called “NEAt: Network Error Auto-Correct”. The idea here is that the system keeps track of what’s going on with your network and notices problems and automatically corrects them. It was designed for an SDN setup where you have a controller that is responding to changes in the network and telling systems what to do.
The event was held at San Jose Conven…

Bringing the Focus back : Firefox Focus (Builds) for Android

Firefox Focus – A Free, Fast Private Browser for....android! On 17th November 2016 Mozilla announced Firefox Focus. A free fast and easy to use private browser for iOS. Firefox Focus was filled with goodies. From inbuilt tracker blocking, content blockers to making privacy the first class citizen. It was all of that. Wrapped in a nice package, but only for Apple Ecosystem. The argument for having focus was to make privacy dead simple and default experience for most people out there. An excellent read is this article "Privacy made simple with Firefox Focus".
And while this was all fine, a lot of us were severely disappointed that we don't have an android version. That all changes now.
Mozilla has released a port of the Firefox Focus source code and I decided to build a port from it. And this is how it looks in my One Plus One.
If you notice it looks almost similar to its iOS counterpart. Focus blocks tracking cookies by default in its system. But there are small design c…

WannaCry : কি এবং কেন

স্টিভেন সবে সকালের কফি টা হাতে করে নিয়ে বসেছে তার ডেস্ক এ. রাতের শিফট থাকলে সব সময়েই হসপিটাল এ তার মেজাজ খারাপ হয়ে থাকে। উপরন্তু রেবেকার সাথে বাড়ি থেকে বেরোনোর সময় ঝগড়া টাও তার মাথায় ঘুরে বেড়াচ্ছিল। বাড়ি ফিরেই আজ তার জন্যে কিছু একটা ভালো কিছু রান্না করে রাখবে বলে ভাবছিলো স্টিভেন। 
এসব চাই পাশ ভাবতে ভাতেই কম্পিউটার তা আনলক করে সে সবে বসেছে, হঠাৎ স্ক্রিন এর ব্যাকগ্রাউন্ড এর ছবিটা দেখে তার ভুরু কুঁচকে গেলো।
"মেরি কি এসব প্রাকটিক্যাল জোকে করছে আমার সাথে?" ভাবলো স্টিভেন। মেরি তাদের নার্স। মাঝে মাঝেই স্টিভেন এর কম্পিউটার এ বসে খুটখাট করে. সেই হয়তো কিছু করেছে, ভেবে পেশেন্ট এর ফাইল তা খুলতে গেলো স্টিভেন, কিন্তু পেলোনা। তাড়াতাড়ি বাকি ফাইল গুলো খুঁজতে গিয়ে কোনোটাই আর পেলোনা। ততক্ষনে বিন্দু বন্ধু ঘাম জমতে শুরু করেছে কপালে স্টিভেন এর. মাথা তুলে রিচার্ড এর সঙ্গে কথা বলতে গিয়ে দেখে রিচার্ড হতভম্ব মুখে তাকিয়ে আছে তার সামনের কম্পিউটার এর দিকে যাতে তখন ছবি  

ওপরের কাল্পনিক লেখা তা হতেই পারতো কোনো ড্যান ব্রাউন এর নভেল। কিন্তু তা হয়ে দাঁড়ায় এক সত্যি ঘটনা যা ব্রিটেন এর NHS ট্রাস্ট এর সত্যিকারের ঘ…

LibrePlanet 2017: Liberating your open source experience

LibrePlanet is a yearly gathering of free software activists, users, and contributors—and, it's my favorite conference of the year. Here's why.
LibrePlanet is run by the Free Software Foundation, and has steadily evolved from a yearly members' meeting with presentations from staff and board members to a full blown two-day conference with speakers and attendees from all over the world. The event brings people who care about free software together to talk about the future of the movement, address current challenges, and celebrate successes.
PreludeI was invited to give a talk at LibrePlanet 2017 on 25th March at MIT, in Cambridge, Massachusetts representing Mozilla as a Tech Speaker. I reached Boston on 25th early morning. Around 1 AM. The journey itself was awesome till I realized that you don't get Uber or Lyft at Boston Airport.

Not that the apps don't function there. They work! Just no driver will be ready to pick you up from Airport at that time. After trying to b…
