Connected carolers advance the lyrics with the space bar, while the server renders a tree selected for the viewer's screen size. The project uses Wish, Bubble Tea, Unicode Braille symbols for higher-fidelity drawing, and pre-rendered trees generated by a Python script. ### Source excerpt A global christmas carol over ssh ## The Life of a Data Byte DevFeed: [The Life of a Data Byte]() Original publisher: [Read original article]() Published: 2020-03-08T08:09:26Z Content type: article Language: en Sources: [Jessie Frazelle]() Topics: [data](), [ASCII](), [Code](), [digital]() Tags: [ascii](), [code](), [data](), [digital](), [encoding](), [storage](), [unicode]() ### AI overview An overview of how bits and bytes have been stored across historical and modern media, followed by an explanation of character encoding with ASCII, Unicode, UTF-8, UTF-16, and UTF-32. ### Source excerpt A byte of data has been stored in a number of different ways as newer, better, and faster mediums of storage are introduced. A byte is a unit of digital information that most commonly refers to eight bits. A bit is a unit of information that can be expressed as 0 or 1, representing logical state. In the case of paper cards, a bit was stored as the presence or absence of a hole in the card at a specific place. If we go even further back in time to Babbage's Analytical Engine, a bit was stored as the position of a mechanical gear or lever. For magnetic storage devices, such as tapes and disks, a bit is represented by the polarity of a certain area of the magnetic film. In modern dynamic random-access memory (DRAM), a bit is often represented as two levels of electrical charge stored in a capacitor, a device that stores electrical energy in an electric field. In June 1956, Werner Buchholz1 coined the word byte2 to refer to a group of bits used to encode a single character of text3. Let's go over a bit about character encoding. We will start with American Standard Code for Information Interchange, or ASCII. ASCII was based on the English alphabet, therefore every letter, digit, and symbol (a-z, A-Z, 0-9, +, -, /, ", ! etc) were represented as a 7 bit integer between 32 and 127. This wasn't very friendly to other languages. In order to support other languages, Unicode extended ASCII. With Unicode, each character is represented as a code-point, or character, for example a lower case j is U+006A, where the U stands for Unicode and after that is a hexadecimal number. UTF-8 is the standard for representing characters as eight bits, allowing every code-point between 0-127 to be stored in a single byte. If we think back to ASCII this is fine for English characters, but other language's characters are often expressed as two or more bytes. UTF-16 is the standard for representing characters as 16 bits and UTF-32 is the standard for representing characters as 32 bits.

It highlights capabilities including ltree, citext, date arithmetic, jsonb, lateral joins, window functions, custom foreign data wrappers, replication slots, range types, statistics, logical decoding, and psql features. ### Source excerpt Postgres has a rich set of features, even when working everyday with it you may not discover all it has to offer. In hopes of learning some new features that I didn't know about myself as well as seeing what small gems people found joy in I tweeted out to see what people came back from. The response was impressive, and rather than have it lost into ether of twitter I'm capturing some of the responses here along with some resources many of the features. @listrophy - $ brew postgresql-update database Though personally I prefer Postgres.app ;) @pat_shaugnessy - ltree Pat has a great post that walks through ltree @billyfung - citext A really handy datatype for case insensitive text @eeeebbbbrrrr - date math with intervals I couldn't agree more on this one, working with time in Postgres is the easiest time I've every had @DataMiller - The jsonb datatype and lateral joins I'd argue it's hard to claim now JSONB is a hidden gem, but lateral joins are certain a great one @ideasasylum - row_number() over(partition http://orders.site_id order by orders.created_at) Window functions are definitely a handy feature was my hidden (to me) discovery this week @franckverrot - Index access method, and custom FDWs @jonjensen0 - Set-returning functions and custom aggregate functions can be very helpful. @ascherbaum - psql -x Psql is indeed awesome and can be well tuned @Abstr_ct - The fact that the docs are fantastic and all hidden gems are actually readily available. Oh, and pl/brainfuck obviously @Halpin_IO - Subnetting and network operations @jkatz05 - Replication slots, both physical and logical. They've made setting up replication infinitely easier. And range types. Because they're awesome. @petereisentraut - Unicode table borders @_avichalp Notify/listen @simonw - The fact that GIN indices can make LIKE queries run fast even if the % isn't just at the end of the string @javisantana - it has a statistics system to plan queries that can be used by the user when accuracy does not matt ## Why I'm Learning Perl 6 DevFeed: [Why I'm Learning Perl 6]() Original publisher: [Read original article]() Author: Evan Miller Published: 2017-07-25T14:50:00Z Content type: opinion Language: en Sources: [Evan Miller]() Topics: [Perl](), [Concurrency](), [Programming](), [Programming language]() Tags: [c](), [concurrency](), [perl](), [programming-language](), [unicode](), [virtual-machine]() ### AI overview Evan Miller explains why he is exploring Perl 6, focusing on its runtime and concurrency capabilities. He highlights MoarVM's event-loop-aware scheduler, continuations, lightweight worker routines, and concurrent bytecode execution without a GIL, while noting that the article is not a full language review. ### Source excerpt The Perl 6 virtual machine is a promising piece of technology: Why I'm Learning Perl 6 ## Understanding Unicode and UTF-8 Character Encoding DevFeed: [Understanding Unicode and UTF-8 Character Encoding]() Original publisher: [Read original article]() Author: Graham King Published: 2012-05-31T22:25:18Z Content type: tutorial Language: en Sources: [Graham King]() Topics: [Programming](), [ASCII](), [Python](), [Go Language](), [.NET](), [Java]() Tags: [ascii](), [c-sharp](), [encoding](), [go](), [java](), [programming](), [python](), [software](), [unicode](), [utf8]() ### AI overview This guide explains how Unicode code points represent characters and how UTF-8 stores them using one to four bytes.
