Why doesn't QUIC work well for machine-to-machine traffic ? Is it due to the lack of offloads/optimizations for TCP and machine-to-machine traffic tend to me high volume/high rate ?

Anecdotally I keep hearing the overuse/abuse of OOP (Object Oriented Programming paradigm), especially in Java, has proved to be counter productive over the last two+ decades. This obviously is a religious topic; but clearly the heavy push for OOP seems to be waning as can be seen from the approach languages like Go have taken and their success.Are there any studies/good articles that looked...
a database noob question, when you say distribute the database to 50 servers all these are shards, correct? MySQL (or any standard RDBMS) can't span more than one server, correct ?
Do you have a source for the number you quoted ?

Most content in the social media platforms are dynamic and generated per user based on their friends, iikes, subscriptions etc. Does this mean search engines don't get to index any of the contents shared in social media platforms ? Does Google deploy any special tricks to crawl and index content that's 'normally' not accessible ?
No, these are not the traditional surnames. What I am referring to is a practice of legally changing the last name (typically father's or grand father's name) to Iyer or Iyengar. To me its a clear on your face statement that the person belongs to that caste and wants to flaunt it.
Fair points. I don't have historical data, but my observation is that the issue of brahmins controlling/dominating lot of sectors was a real problem at some point and the reservation system was a populist response that did provide some benefit for oppressed castes, but created a whole bunch of other problems and unintended consequences. And its still remains such a hot button populist issue no political party would dare implementing the required reforms. The unintended consequence is the emigration of a lot of people from the "higher" castes. I guess its hard to say if it had any material impact on India's progress but the "higher" caste population that doesn't have the means/resources to emigrate is put in a real difficult situation.
I am an Indian and have been in US for many years. There is one thing I have noticed among brahmins, during their Naturalization process many of them change their last names to Iyer or Iyengar (two sects of Brahmins).
I am referring to guys from the southern part of India where I am from. Its not a common practice there.
My interpretation of this is these folks have a perceived sense of superiority feeling about their caste and having it in the last name is a form of boasting.
In South India there has been a social movement in the last few decades to allocate quotas for "lower" caste members in universities and govt jobs to stop the domination of brahmins (merits, or lack there of, of the quota system is whole different topic). So having Iyer or Iyergar as last name would be frowned upon/judged endlessly there. May be they feel a sense of freedom here in US that prompts this behavior.
Is this applicable for Go as well ?

https://queue.acm.org/ is providing membership free access for three months. Looking for suggestion for good papers to read. My primary areas of interest, concurrency/performance at scale, distributed systems, authentication/authorization.
Genuine questions as someone with no experience in dealing with large sclae log aggregation: Can you share some details on what kind of issues you ran into in production with Elastic Search that needed a dedicated team to manage ?
Are there videos for MIT's distributed systems course ? Can't seem to locate it in the site.

I have good ideas for side projects and in general want to keep myself primed by solving algorithmic problems (I am an individual contributor with 15+ years exp and no plans to move to management roles).But I struggle with self control and discipline. I come home on a Friday evening and end up binge watching or do unproductive/unnecessary things online till like 3 or 4 AM and screw up the next...

Its an area I suck, writing good functionality/integrations tests for the features I implement.Looking for blogs/articles from developers who are better at this, tips, practices etc.
Can you provide some references to open source implementations of Succinct implicit trees ? How different are they from a simple unbalanced BST ?
Any idea why it works for v6 but not v4 ? SSH authentication itself is agnostic to the IP version, no ?
can someone help me understand this better.. Did Cisco leave a user public key in the switch and the private key has leaked ? To exploit this vulnerability attacker has to get hold of that private key ?
What does he mean by this "My first advice would be to choose your ancestors carefully." ?
Looks like Duo provides a 2FA for accessing any application ? Does it work for any random app ? Are there any details online about the technical details on how that works ?
Do you know if gcp firewall has limits on the number of rules and what those limits are ?

When migrating from Linux firewall to AWS Security Groups are there any issues to be aware of ? I believe number of rules is limited in AWS Security Groups. Are there other limitations or known issues ?
Curious, what specifically does nftables offer in this context that iptables doesn't ?

Can you share some blog posts, presentations about modern monitoring & alerting framework used by web scale companies ?I hear a lot of about Graphite, Prometheus, Nagios, Datadog etc. But missing the big picture view of how to put the pieces together for a complete monitoring stack that is scalable and efficient.
To be specific, the requirement is to run containers on all the instances. Container connectivity will be through a L3 network using BGP
few thousand EC2 instances ideally in a flat L3 network (using BGP)

- what are the main technical differences in the way networking is implemented in AWS vs GCP ?- Are there any commonly used networking solution with physical hardware (Cisco, Arista etc.) that doesn't work well or needs a redesign to work with either provider ?- What are the potential gotchas with either when running at scale.

Apparently CA's platform can monitor & analyze millions of requests going through JVM nodes per second. Are there details about how exactly the JVM monitoring is implemented ? Are there similar open source tools ?

SANS.org paper on NIDS says the following "performs an analysis for a passing traffic on the entire subnet. Works in a promiscuous mode, and matches the traffic that is passed on the subnets to the library of knows attacks"Is there any public list of such known attacks ? Also, are there any reliable open source software in Linux that can do NIDS ?

It looks really expensive (~$140 per month per employee ?) but the company seems to be growing crazy and also a very good place to work for.How are they able to pull off such a high subscription price ?
