In basketball, "efficiency" typically refers to a player's ability to contribute positively to their team's performance relative to the amount of resources (like minutes played, possessions used, or shots taken) they require to do so. There are several ways to measure efficiency, but one commonly used statistic is Player Efficiency Rating (PER), developed by researcher John Hollinger. Player Efficiency Rating is a comprehensive statistic that summarizes a player's statistical contributions into a single number.
Genesis block message by Ciro Santilli 37 Updated +Created
Inscription added by Satoshi Nakamoto on the Genesis block containing:
The Times 03/Jan/2009 Chancellor on brink of second bailout for banks
which is a reference to: www.thetimes.co.uk/article/chancellor-alistair-darling-on-brink-of-second-bailout-for-banks-n9l382mn62h wihch is fully titled:
Chancellor Alistair Darling on brink of second bailout for banks
The "Alistair" was slikely removed due to limited payload concerns.
Through the newspaper reference, the message proves a minimal starting date for the first mine.
And it hints that one of Bitcoin's motivation was the financial crisis of 2007-2008, where banks were given bailouts by the government to not go under, which many people opposed as the crisis was their own fault in the first place. A notable related stab is taken at Len Sassaman tribute.
We can extract the image from the blockchain ourselves by starting from: blockchain.info/block-height/0?format=json.
From that page we manually extract the hash 000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f and then:
wget -O 0.hex https://blockchain.info/block/000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f?format=hex
xxd -p -r 0.hex
and that does contain the famous genesis block string:
EThe Times 03/Jan/2009 Chancellor on brink of second bailout for banks
The JSON clarifies that the data is encoded in the script field of the transaction input:
{
      {
         "script":"04ffff001d0104455468652054696d65732030332f4a616e2f32303039204368616e63656c6c6f72206f6e206272696e6b206f66207365636f6e64206261696c6f757420666f722062616e6b73"
The extra E (0x45 in ASCII) in EThe Times is just extra noise required by the script, we can break things up as:
04ffff001d0104 45 5468652054696d65732030332f4a616e2f32303039204368616e63656c6c6f72206f6e206272696e6b206f66207365636f6e64206261696c6f757420666f722062616e6b73
where:
  • 54 is T
  • the 04ffff001d0104 part just doesn't show up on the terminal because it is not made of any printable characters.
The initial 04 is OP_RETURN.
TODO what is actual the meaning of the ffff001d010445 part? @defango twitter.com/defango/status/1642750851134652417 comments:
04ffff001d0104 is a hexadecimal string. It is commonly used in the Bitcoin network as a part of the mining process. Specifically, it is used as the target value for a block to be considered valid by the Bitcoin network.
This value represents the level of difficulty required for a miner to generate a block that meets the network's criteria. The first four bytes, 04ffff, represent the maximum possible target value. The next three bytes, 001d01, represent the current difficulty level
while the final byte, 04, is a padding byte. In summary, this value sets the difficulty level for mining a new block in the Bitcoin network.
TODO the output of the transaction has a jumbled script, likely just a regular output to get things going, can't be arbitrary like input.
Double-double by Wikipedia Bot 0
The term "double-double" can have different meanings depending on the context in which it is used: 1. **Culinary Context**: In some coffee shops, notably the Canadian chain Tim Hortons, a "double-double" refers to a coffee order that consists of two creams and two sugars. 2. **Sports Context**: In basketball, a "double-double" is a statistical term that signifies a player achieving double digits in two different statistical categories during a single game.
In basketball, a "block" refers to a defensive action where a player legally intercepts or deflects an opponent's shot attempt. This can occur when the defensive player jumps and makes contact with the ball, preventing it from going into the basket. Blocks are notable for several reasons: 1. **Defense**: They are a critical component of strong defensive play, showcasing a player's timing, athleticism, and ability to read the opponent's movements.

A basketball winning streak refers to a scenario in which a team wins multiple consecutive games without losing any in between. Winning streaks can vary in length, from just a few games to many. They are often a testament to a team's skill, cohesion, and sometimes favorable matchups against opponents. Winning streaks are significant because they can indicate a team's form and confidence level. They can boost team morale and fan support and play a crucial role in a team's standings during the regular season.
As of October 2023, the Basketball Champions League (BCL), established in 2016, has become one of Europe's premier club basketball competitions. The league features teams from various European domestic leagues and aims to provide an exciting platform for clubs outside the EuroLeague and EuroCup.

Gel electrophoresis alelle determination by Ciro Santilli 37 Updated +Created
In the case of indel mutations (see limits of gel electrophoresis for minimal size difference issues), it is possible to determine the allele with gel electrophoresis. You can just read out the alleles right in the gel. It is a thing of beauty.
As of 2020, this method appears to be much cheaper than DNA sequencing approaches.

In basketball, an assist is a statistic that credits a player for a pass that directly leads to a made basket by a teammate. The player who makes the pass is awarded the assist if the recipient scores the basket without any significant interruption, such as dribbling or excessive delay. Assists are important because they reflect a player's ability to facilitate teamwork, enhance ball movement, and create scoring opportunities for others.

Advanced statistics in basketball refer to a set of metrics and analytical tools that go beyond traditional statistics (like points, rebounds, and assists) to provide deeper insights into player performance, team dynamics, and overall game strategy. These advanced metrics help coaches, analysts, and fans evaluate the effectiveness of players and teams in more nuanced ways.

Pinned article: ourbigbook/introduction-to-the-ourbigbook-project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.
