So yeah that actually happened! I’ve always wanted to publish a book and thanks to Apress publishing - that is a reality now. The book is titled “Practical Docker With Python: Build, Release and Distribute your Python App with Docker” and is targeted at people who are new to Docker and want to containerize their application (with an example Python chat bot). The book starts with a brief introduction to containers and Docker, guides you on how to get started with Docker before diving into deeper topics such as Docker Networks, Volumes and Compose.

I recently published couple of articles elsewhere: How to Increase Container Security and Ward Off Threats - Adobe Tech Blog 5 OpenSource tools for container security - OpenSource.com Scanning Docker Images for Vulnerabilities with Aqua Microscanner - previously, on my blog Do give them a read.

E3 has come and gone by and most of the year’s press conferences were boring (what was EA even smoking?). Having said that, some of these did grab my attention. Below are a list (in no specific order) of gameplay/trailers/things I’m looking for and thought were good. Enjoy Skyrim Very Special Edition - Hilarious and very well done The Elder Scrolls Blades - FPS RPG for mobile, play on portrait, landscape, sounds great, PvP, PvE,town building, and coming to phones, PC and VR - and all this for free.

Containers are slowly becoming the standardized units of deployment. As containers become more popular, they also become the focus targets for attacking the system via vulnerabilities present in the packages within the image. There are quite a few container vulnerability scanning solutions (example: Clair, Twistlock, now Prisma Cloud, Aqua – however most of them are either commercial or require an elaborate setup, which makes it difficult for individual developers to involve them as part of the container build process.

Long time, no write! Newsletters have become all the rage these days and I guess for good reason - they’re curated, come in (usually) once a week and typically offer a respite from the deluge of news that comes in why typical RSS Feeds or via Twitter. Naturally I subscribed to few initially and then the list of newsletters increased - and now I am stuck with a newsletter bomb in my Inbox

VR and me go like chalk and cheese - ever since a kid, I’ve had motion sickness which limited me from playing most FPS games and my last attempt at VR(at IGX 2016) was a disaster - I barely could withstand 30 seconds of VR. Granted the game selection was bad - for me anyway (Driveclub on PSVR) - still I didn’t expect that bad of a reaction. With that bit of context, the reactions that flew in when I told the folks that I(well Jo, my wife, to be more precise) bought the Rift was expected.

In Chef parlance, databags are global variables saved in JSON format and are stored and accessible on the Chef server. Given that these are indexed and can be searched up along with the fact that they can be encrypted make them ideal candidates to store secrets such as credentials/ssh keys. Chef provides an easy way to search and fetch databag and databag items from within a recipe: For ex to fetch a databag called admins, it’s as easy as:

Among the services I look after, the biggest and high-profile - is the user facing website. The website is your bog-standard typical frontend(powered by Express/Angular) which fetches data via an API which is powered by the backend(built on Rails). Typical flow is that Express receives the request from the browser, makes a request to the backend which is then served using Rails API via nginx which acts as the reverse proxy.

I had an instance today where a local VM(which is provisioned by Xenserver) was running low on disk space and wanted to increase the disk space allocated to it. Last time when I did it by increasing the space from within Xen Manager, I failed miserably(the VM was configured with LVM and neither pvscan or lvscan was able to see the increased space). This time I tried a different approach:

End of the year is here and while other services are busy sending Year in 2016 report, there sparked a mini gaming report in our telegram group and I decided to compile my gaming in 2016 report. At the start of the year I had decided to finish more games this year and I guess I did a pretty decent in accomplishing this. So here’s my summary Games finished this year: # PC:
