cnlwsu··on Amazon Launches Managed Cassandra Service
No, nor do I know of any desire to do so
cnlwsu··on Amazon Launches Managed Cassandra Service
The contributors for Cassandra are from a group of companies that use it, not a single company that is trying to be profitable from it. I think this is a positive for the community, even if they don't contribute back since it would provide an easy getting started platform.

> what am I missing here?

Mostly that your believing Scylla marketing literature and paid benchmarks over what people actually use and experience. Theres thousands of large Cassandra deployments and a hand full of Scylla ones and it's not because people didn't do their research. If they did to ScyllaDB though it will probably kill the product, with Cassandra this is more of a positive for the community.

cnlwsu··on Show HN: HugeGraph – An open source fast and highly scalable graph database
Why https://github.com/hugegraph/hugegraph/commit/cad89c3bafce08... ? Its Ok to copy things from other projects but it seems unnecessary copy it and strip ownership like that then put "Copyright 2017 HugeGraph Authors" on it.

The escape key is there in terminal in same position it would be if there was no touchbar. Its been a complete non issue that people who do not have the touchbar like to complain about.

They took right approach. Don't treat it like a religion and do what works best for your team and project. There is no single perfect model so be willing to change if it makes sense.

cnlwsu··on Open-sourcing a 10x reduction in Apache Cassandra tail latency
Answered a bit before but they have a team that knows c* well. Cassandra is proven to handle petabytes at scale in production systems.
cnlwsu··on Open-sourcing a 10x reduction in Apache Cassandra tail latency
Data density is a thing. If u putting 10tb on a c* host, switching to Scylla doesn’t fix the issues that putting 1pb of data on a host would involve (ie backing that up). Throughput of 100mb of data done in marketing benchmarks are rarely relevant.
cnlwsu··on The suicide rate for farmers in the U.S. is more than double that of veterans
"The grass is always greener". I grew up on a dairy farm, its easy to romanticize it but the reality of waking up to literally chip and shovel frozen shit at 5am (almost daily chore to clean barns in winter) gets old after a decade. I worked hard to get out of farming and never want to go back. I love my tech job.
cnlwsu··on Ask HN: Learning NoSQL, papers and books
“Yeah, but Postgres” is the new “Is it webscale?” For any db related thread. They found a blue hammer that will work for every problem and want everyone to know.

People usually don't get jobs maintaining sqlite databases. Doesn't mean that sqlite isn't used by everyone, its mostly used in client apps though.
cnlwsu··on Note to Google Employees from CEO Sundar Pichai
Keep politics/religion out of work. Its one thing to rant on reddit at end of day, its another to broadcast it to co workers. What did he expect would happen? His little write up would change everyones mind? Both left/right are extremists these days and will never change. All you will do is alienate and anger a bunch of co workers for a few pats on back from "your" side. While the smart people will put heads down and get actual work done at work and talk politics at end of day at a bar with friends/family like the rest of the country.
cnlwsu··on Clojure will affect the way you think about programming
why not both
cnlwsu··on Clojure will affect the way you think about programming
For people familiar with java, the jvm is an upside. Being able to use libraries (especially client ones) from your project can be very useful. The amazing interop support is very nice if your pragmatic over purist and don't plan on rewriting a ton of things.
cnlwsu··on Clojure will affect the way you think about programming
Java still has same issue too with bored engineers. Over engineering happens. AbstractSingletonProxyFactoryBean anyone? But really strongly typed languages like java is easier than most dynamic typing language to jump into _if the project is sane_.
cnlwsu··on Clojure will affect the way you think about programming
I worked on a large-ish clojure project with ~15 (people left and joined) person team for years and I haven't experienced any of your points. Sounds more like an new project with a group of people not quite familiar with the language yet, which would have the problems you listed in any language.

Easy multi datacenter high availability can benefit smaller datasets as well.
cnlwsu··on The JVM is not that heavy
They also have never caught up feature wise, and actually have gotten further behind since initial release. Also the benchmarks are lies (tbf, all benchmarks are lies).
cnlwsu··on How Discord Stores Billions of Messages Using Cassandra

cnlwsu··on Elassandra: Elasticsearch implemented on top of Cassandra
Closest thing Cassandra has to behaving like a search engine is the new SASI indexes. Good deep dive here: http://www.doanduyhai.com/blog/?p=2058 which describes how its different from elastic search in "SASI vs Search Engines" section.

    - SASI requires 2 passes on disk to fetch data: 1 pass to read the index files and 1 pass for the normal
    Cassandra read path whereas search engines retrieves the result in a single pass (DSE Search has a singlePass option too).
    By laws of physics, SASI will always be slower, even if we improve the sequential read path in Cassandra

    - Although SASI allows full text search with tokenization and CONTAINS mode, there is no scoring applied
    to matched terms SASI returns result in token range order, which can be considered as random order from the
    user point of view. It is not possible to ask for total ordering of the result, even when LIMIT clause is used.
    Search engines don't have this limitation

    - last but not least, it is not possible to perform aggregation (or faceting) with SASI.
    The GROUP BY clause may be introduced into CQL in a near future but it is done on Cassandra side,
    there is no pre-aggregation possible on SASI terms that can help speeding up aggregation queries

cnlwsu··on Scaling to 100M: MySQL Is a Better NoSQL
I may be reading this wrong, but I think they are purposing a not C not A not P solution... thats "ok" fast? They explain how to make a single mysql instance run as key-value but I dont understand how it becomes master-master or cross DCs. Wonder if they run Jepsen or do any partition tolerance tests given their mentioning it.

cnlwsu··on Slack raises $200M at $3.8B valuation for business messaging
The new interface is slow and all the downtime is frustrating. Wish we were using slack
cnlwsu··on Wow, Perl 6 [video]
The next sentence says:

> These people tend to be drawn towards programming languages that are built out of small pieces with a consistent philosophy from the ground up, such as lisp or Haskell.

If you like go and dislike perl its to his point.

A TLDR (because apparently); People who like games that are complex because of complex rules like perl. People who like complex games with simple rules dislike it.

cnlwsu··on Cursive, an IDE for Clojure and ClojureScript, has reached 1.0
I've been using this awhile and will definitely buy a license. Congratulations on the release!
