The issue involves std::char_traits: LLVM 19 removed its unconstrained base template because the C++ Standard does not require it for unsigned-character types. Code may need string concatenation and related operations replaced or a correct custom specialization provided. ### Source excerpt Brief post on a somewhat vexing and irritating C++ problem I ran into some time ago. I hope that this page will help other people deal with this problem more quickly than I did. I've long used std::basic_string, an unsigned char string, for fiddling with bits. You could use a regular char string, but especially when doing cryptographic or sub-byte operations, it is more convenient to not have to deal with sign bits. ## Advanced String Manipulation in Twig with Craft CMS DevFeed: [Advanced String Manipulation in Twig with Craft CMS]() Original publisher: [Read original article]() Author: andrew@nystudio107.com (Andrew Welch) Published: 2024-05-01T17:39:00Z Content type: tutorial Language: en Sources: [nystudio107 | Articles on modern web development.]() Topics: [Content Management System](), [PHP](), [Library](), [Code](), [phpstorm]() Tags: [advanced](), [craft](), [hidden](), [how-to](), [insights](), [learn](), [manipulation](), [plugins](), [powers](), [required](), [string](), [twig](), [unleash]() ### AI overview This tutorial explains how to perform advanced string manipulation in Twig with Craft CMS without additional plugins.

It explains how to obtain heap snapshots, compare snapshots over time, and inspect object references and retained size while noting that increased memory or retained size alone does not conclusively prove a leak. ### Source excerpt 最近解决了一个 Node.JS 应用内存泄漏 Bug，顺便学会了用 Chrome DevTools 去看 heapdump 文件。这里做一些简单的记录。 如何「优雅地」获得 heapdump 文件 由于我们所有应用都是以容器部署的，所以要去获得某个容器内的文件，并拷贝到本地难度还是比较大，也非常麻烦。考虑到调试时或许会需要下载非常多次的 snapshot 文件，建议可以包下 heapdump 库，做成一个接口，把文件 dump 之后再传输给客户端，这样一劳永逸。 ## Multiline strings in ES6 JavaScript DevFeed: [Multiline strings in ES6 JavaScript]() Original publisher: [Read original article]() Author: Jack Tarantino Published: 2015-11-29T23:59:53Z Content type: tutorial Language: en Sources: [Jacopo Tarantino]() Topics: [JavaScript](), [es6](), [Template]() Tags: [best-practices](), [es6](), [javascript](), [string](), [template](), [template-strings](), [templates]() ### AI overview A tutorial on ES6 Template Strings in JavaScript, covering multiline strings, interpolation, tagged template strings, and older ES5 techniques for writing multiline strings. ### Source excerpt The new kid in town is called Template Strings. Template Strings are demarked by a backtick(`) on either end and can contain other backticks if they are escaped by a backslash(ie. let my_string = `some cool \`escaped\` thing`). This new kind of primitive in JavaScript is different from ## Python Helpers for String/Unicode Encoding, Decoding and Printing DevFeed: [Python Helpers for String/Unicode Encoding, Decoding and Printing]() Original publisher: [Read original article]() Author: Chris Hager Published: 2015-11-23T00:00:00Z Content type: tutorial Language: en Sources: [Chris Hager]() Topics: [Python](), [Code](), [pdf](), [console](), [Windows]() Tags: [console](), [decoding](), [encoding](), [pdf](), [python](), [string](), [windows]() ### AI overview This tutorial presents two public-domain Python helpers: make_compat_str decodes bytes or strings into Unicode, while print_to_console prints Unicode safely across terminals and output encodings. The helpers are used in PDFx. ### Source excerpt String encoding and decoding as well as encoding detection can be a headache, more so in Python 2 than in Python 3. Here are two little helpers which are used in PDFx, the PDF metadata and reference extractor: make_compat_str - decode any kind of bytes/str into an unicode object print_to_console - print (unicode) strings to any kind of console (even windows with cp437, etc.) All of this code is in the public domain via The Unlicense. ## Let's Build A Simple Interpreter.

It also references a video demonstrating the behavior. ### Source excerpt When I was doing a fair bit of Ruby I often used the TextMate's shortcut (Ctrl+:) to convert a Ruby String to a Symbol or a Ruby Symbol to a String. It's something I've periodically missed while doing Clojure, and yesterday I found myself in the middle of a refactoring that was going to force the conversion of 5+ Clojure Keywords to Strings. The following emacs lisp is my solution for toggling between Clojure Strings and Keywords. The standard disclaimers apply - it works on my machine, and I've never claimed to know emacs lisp well.

It introduces a series on probabilistic analysis of Google's ngrams for tasks including spelling correction, word segmentation, typing prediction, and cipher decoding. ### Source excerpt We are about to begin a series where we analyze large corpora of English words. In particular, we will use a probabilistic analysis of Google's ngrams to solve various tasks such as spelling correction, word segmentation, on-line typing prediction, and decoding substitution ciphers. This will hopefully take us on a wonderful journey through elementary probability, dynamic programming algorithms, and optimization. As usual, the code implemented in this post is available from this blog's Github page, and we encourage the reader to use the code to implement our suggested exercises. ## Basic Computer Science DevFeed: [Basic Computer Science]() Original publisher: [Read original article]() Published: 2011-08-31T00:00:00Z Content type: tutorial Language: en Sources: [Radek Pazdera]() Topics: [Computer science](), [Programming](), [coding]() Tags: [computer-science](), [concatenation](), [programming](), [programming-languages](), [science](), [string]() ### AI overview A beginner-oriented introduction to foundational computer science concepts, including alphabets, symbols, strings, and formal languages.

It explains how a computational model recognizes a language by accepting or rejecting strings. ### Source excerpt The first step in studying the sorts of possible computations (and more interestingly, those things which cannot be computed) is to define exactly what we mean by a "computation." At a high level, this is easy: a computation is simply a function. Given some input, produce the appropriate output. Unfortunately this is much too general. For instance, we could define almost anything we want in terms of functions. Let $ f$ be the function which accepts as input the date of California Super Lotto drawings, and returns the set of winning numbers for that date. ## switch-window reaches 0.8 DevFeed: [switch-window reaches 0.8]() Original publisher: [Read original article]() Author: Dimitri Fontaine PostgreSQL Major Contributor; Author Published: 2010-09-13T15:45:00Z Content type: article Language: en Sources: [Dimitri Fontaine]() Topics: [coding](), [Utility Software](), [GUI]() Tags: [keyboard](), [layout](), [split](), [string](), [window]() ### AI overview The author describes updating the switch-window utility to use the keyboard layout from quail-keyboard-layout, using the first ten letters as labels and direct-switch keys instead of hard-coded numbers. The change is intended to improve suitability for cssh users. The article also briefly mentions an upcoming el-get release and asks readers to test it and report problems. ### Source excerpt I wanted to play with the idea of using the whole keyboard for my switch-window utility, but wondered how to get those keys in the right order and all. Finally found quail-keyboard-layout which seems to exists for such uses, as you can see: (loop with layout = (split-string quail-keyboard-layout "") for row from 1 to 4 collect (loop for col from 1 to 12 ("q" "w" "e" "r" "t" "y" "u" "i" "o" "p" "[" "]") ("a" "s" "d" "f" "g" "h" "j" "k" "l" ";" "'" "\\") ("z" "x" "c" "v" "b" "n" "m" "," "." "/" " " " ")) So now switch-window will use that (but only the first 10 letters) instead of hard-coding numbers from 1 to 9 as labels and direct switches. That makes it more suitable to cssh users too, I guess.
