dual screen phone: LG G8X
https://www.theverge.com/2019/10/22/20926719/lg-g8x-dual-screen-spƄecs-features-price-release-date-us-announced
:format(webp)/cdn.vox-cdn.com/uploads/chorus_image/image/65524727/IMG_0269_2.0.jpg)
The G8X ThinQ is a unique take on a dual-screen phone. Instead of using a foldable screen, like Samsung’s Galaxy Fold, or attaching an entire second screen with a hinge, like Microsoft’s upcoming Surface Duo, LG just made a normal phone with one screen. The second screen is based entirely within a case that the G8X slips into. Once it’s in, you can turn the second screen on and off or remove the phone later and just use the device as normal.

Python 2 vs Python 3:
The future of databases, by Dr. Michael Stonebraker
Very opinionated and eloquent overview of history and future of database systems
by one of its major creators and contributors.
Creator of 9 database companies / products, including Postgres.
Winner of Turing Award, the highest recognition in Computer Science.
In a nutshell: while higher level languages, including SQL are here to stay,
current architecture of database systems is not optimal match for current technology and needs,
and is being replaced by "NewSQL" There are three major domains of database systems:
* Data Warehousing: best served by "columnar storage" engines.
* Transaction data systems: best served by "in memory" engines.
* Non-relational systems (document, graph, array db systems, etc)

Kinesis works with streaming data.
Kafka works with streaming data too.
Kinesis Streams is like Kafka Core.
Kinesis Analytics is like Kafka Streams.
A Kinesis Shard is like Kafka Partition.
They are similar and get used in similar use cases.
Data is stored in Kinesis for default 24 hours, and you can increase that up to 7 days.
Kafka records are by default stored for 7 days and you can increase that until you run out of disk space. In fact, you can decide by the size of the data or by date. You can even use compaction with Kafka so it only stores the latest timestamp per key per record in the log.

cloud: C++, Rust, WASM on AWS Lambda; Lambda Layers
Introducing the C++ Lambda Runtime | AWS Compute Blog
Runtime API allows you to write your Lambda functions in any language, provided that you bundle it with your application artifact or as a Lambda layer that your application uses.
As an example of using this API and based on the customer demand, AWS is releasing a reference implementation of a C++ runtime for Lambda. This C++ runtime brings the simplicity and expressiveness of interpreted languages while maintaining the superiority of C++ performance and low memory footprint.
When building serverless applications, it is quite common to have code that is shared across Lambda functions. It can be your custom code, that is used by more than one function, or a standard library, that you add to simplify the implementation of your business logic.
Previously, you would have to package and deploy this shared code together with all the functions using it. Now, you can put common components in a ZIP file and upload it as a Lambda Layer. Your function code doesn’t need to be changed and can reference the libraries in the layer as it would normally do.
A function can use up to 5 layers at a time. The total unzipped size of the function and all layers can't exceed the unzipped deployment package size limit of 250 MB.

Google QUIC protocol vs TCP
QUIC - Wikipedia
"QUIC (pronounced 'quick') is a general-purpose[1] transport layer[2] network protocol initially designed by Jim Roskind at Google,[3] implemented, and deployed in 2012,[4] announced publicly in 2013
While still an Internet Draft, QUIC is used by more than half of all connections from the Chrome web browser to Google's servers. Most other web browsers do not support the protocol.
Among other applications, QUIC improves performance of connection-oriented web applications that are currently using TCP.[2][9] It does this by establishing a number of multiplexed connections between two endpoints over User Datagram Protocol (UDP). This works hand-in-hand with HTTP/2's multiplexed connections, allowing multiple streams of data to reach all the endpoints independently, and hence independent of packet losses involving other streams. In contrast, HTTP/2 hosted on Transmission Control Protocol (TCP) can suffer head-of-line-blocking delays of all multiplexed streams if any of the TCP packets are delayed or lost.

AC / HVAC SEER Efficiency Savings Calculator
SEER Efficiency Savings Calculator | HVACDirect.comSeasonal energy efficiency ratio - Wikipedia
The efficiency of air conditioners is often rated by the seasonal energy efficiency ratio (SEER)
The SEER rating of a unit is the cooling output during a typical cooling-season divided by the total electric energy input during the same period. The higher the unit's SEER rating the more energy efficient it is. In the U.S., the SEER is the ratio of cooling in British thermal unit (BTU) to the energy consumed in watt-hours.
