I spoke about Observability at #testbash yesterday. This is a thread of references from my presentation.

Observability is about being able to ask arbitrary questions about your environment without having to know ahead of time what you wanted to ask.
Ref: honeycomb.io/wp-content/upl…
What is the difference between Observability, Monitoring, and Testing? @copyconstruct has a fantastic visualisation and explanation.
Ref: medium.com/@copyconstruct…
@copyconstruct Observability is gaining momentum because the complexity of our systems makes it challenging for us to identify everything that we should monitor or test. @mipsytipsy writes about this in her argument for testing in production.
Ref: techbeacon.com/app-dev-testin…
@copyconstruct @mipsytipsy How do you explore this for your systems? @RobMeaney says that observability starts with simple questions.

@copyconstruct @mipsytipsy @RobMeaney I recommend the @honeycombio hands-on scenarios that let you explore observability through real production problems using anonymised data in a sandbox environment. honeycomb.io/play/
They also have excellent whitepapers and guides to read honeycomb.io/resources/whit…

I'm not sure how long I have the patience to keep participating in the same conversations in the testing community. The more I connect beyond our discipline, the more I feel that we've been talking in isolation for over a decade and working ourselves into a corner.
Testers talk about how to automate, how to refactor, exciting new tool X, automation strategy, how to work with developers, reporting to stakeholders, certification, communication, customer empathy, and how the testing role changes in agile/whatever.
When you look back, we've been talking about these things for a long time. Spot the difference in these testing conference programs from 2009.

TO WHAT EXTENT CAN THIS JOB TAKE YOU - Supervisory level, Managerial level, Executive level, or a dead end?

A #Thread of what you should know about your current job and what you can do to manage your career.
Some people get into a job, spend years on the same role and same position without growth.

Some times, salary may change but there is no tangible career growth - you need to ask questions.
What's career growth?

Career growth is the process of moving from one point of the corporate ladder to another. One of the most popular ways through which career growth is achieved is through promotions.

a-Since completing my job search, I feel there are things that could be helpful for others who will be doing this for the first time. So I am sharing some experiences (from application prep -> interview) in hopes that someone will find them useful. #thread
b-Disclaimer: I applied to R1 and mostly chemistry or biochem depts. And even with sharing experiences with others at @futurepi_slack, I’ve found many who would disagree on many things or had different experiences. So these are MY opinions.
c-Also this assumes that you’ve developed your research ideas and they are strong and exciting to more than just you. Definitely put a lot of work into doing that.

Observability (o11y) and formal methods (fm) are very different things, and Charity and I have very few skills in common, but we're both selling the same thing: the power to understand systems. And I think we often have the same difficulties in convincing people.
Software engineering is hard and we're not very good at it. Our concerns are not just programs but software systems, a constant dialogue between the actors, the machine, and the world that leads to surprising and dangerous emergent phenomena.
Most mainstream correctness techniques only work at the local code level. Verifying properties between just two independent programs is near impossible with just local properties, regardless of how you encode them. Humans are bad at handling complexity and bad at realizing this.

Cow is 'Mata' for RSS/BJP & other Hindutva affiliates - we ask for votes in its name, lynch people & even demand a "Rashtra Mata" status for it. But for the sake of elections, we may forget our Mata.

This #thread intends to share such instances of our political tactics!
1) "BJP has no Plan to Ban Beef in Goa" says Amit Shah

2) BJP candidate for Kerala Lok Sabha bypoll promises quality beef if elected!
