DevFeed: [How fast is C++23's std::flat\_map?]() Original publisher: [Read original article]() Author: Daniel Lemire Published: 2026-09-16T20:26:36Z Content type: article Language: en Sources: [Daniel Lemire]() Topics: [Data structures](), [Library](), [gcc](), [LLVM](), [clang]() Tags: [array](), [arrays](), [clang](), [gcc](), [llvm](), [overhead](), [speed](), [standard-library]() ### AI overview This article benchmarks C++23's std::flat_map, a sorted container backed by parallel arrays of keys and values. It explains serialization and loading considerations, then compares insertion and lookup performance with std::map. Random-order insertion becomes quadratic as the container grows, while increasing-order or bulk insertion is much faster; random lookups can also be faster for large maps because std::flat_map uses less memory. ### Source excerpt C++23 added a new type to the standard library: std::flat_map. There is also a std::flat_set and other variants, but let me focus on std::flat_map. A flat map is a sorted vector of keys next to a vector of values. A query is a binary search over the sorted keys. You need a recent standard library: ...

It also describes a benchmark parsing three JSON documents with separately trained PGO builds and comparing their speed against a profile-free baseline. ### Source excerpt When a compiler optimizes your program, it has to guess. Which functions are worth inlining? Which side of a branch is the common one? Which method does this interface call actually reach? At compile time it cannot know, so it uses heuristics. Profile-guided optimization (PGO) replaces the guessing with measurement: you run your program, record ... Continue reading Profile-guided optimization in Go ## How fast is C++26's std::hive?

In the reported tests, hive insertion costs about twice as much as vector insertion, while iteration is about eight times slower than vector and no faster than linked-list iteration. ### Source excerpt C++26 adds a new container to the standard library: std::hive. It is meant to occupy the ground between std::vector and std::list. Like a vector, it keeps its elements in contiguous blocks of memory, so scanning it does not require you to chase a pointer for every element. Like a list, it never moves an element ...

It covers ascending, descending, comparator-based, and selector-based checks, which return true for correctly ordered collections or collections with fewer than two elements. The checks stop when they find an unordered pair. ### Source excerpt Image generated using Perplexity Kotlin 2.4.0-Beta1 introduces a small but powerful addition to the standard library: a set of new extension functions that lets us check whether a collection is already sorted. With these extension functions, we can check whether elements have already been sorted without resorting them. New Functions .isSorted() .isSortedDescending() .isSortedWith(comparator) .isSortedBy(selector) .isSortedByDescending(selector) All of these return true if: The elements are in the expected order, or The collection has fewer than two elements.These functions are optimized -- they stop checking as soon as an unordered pair is found, so they handle large inputs efficiently.Code samplesdata class User(val name: String, val age: Int)fun main() { val numbers = listOf(0, 1, 2, 3, 4, 5, 6, 7, 8, 9) println("Numbers: isSorted") println(numbers.isSorted()) // true println("Is sorted descending") println(numbers.isSortedDescending()) // false // Users list val users = listOf( User("Alice", 21), User("Balley", 34), User("Charles", 29), ) println("Users: isSorted by Age") println(users.isSortedBy(User::age)) // false val comparator = Comparator{ user, user2 -> user.name.length.compareTo(user2.name.length) } println("Users: isSortedWith(comparator)") val sortedList = users.sortedWith(comparator) println("Users: Name by length ${sortedList.joinToString()}") // Output: Users: Name by length User(name=Bob, age=31), User(name=Alice, age=24), User(name=Charlie, age=29) println(sortedList.isSortedWith(comparator)) // true }References What's new in Kotlin 2.4.0-Beta1 | Kotlin ## Why Ruby Is Well Suited for Advent of Code DevFeed: [Why Ruby Is Well Suited for Advent of Code]() Original publisher: [Read original article]() Author: Tony Yunker Published: 2025-12-02T14:00:00Z Content type: opinion Language: en Sources: [Hashrocket]() Topics: [Advent of Code](), [Ruby](), [Programming](), [Data structures]() Tags: [advent-of-code](), [data-structures](), [programming](), [ruby](), [standard-library](), [tooling]() ### AI overview This opinion article explains why the author prefers Ruby for Advent of Code programming puzzles, highlighting Ruby's flexibility, data structures, standard library, and tooling. It also notes that Ruby's metaprogramming can cause bugs in larger production codebases. ### Source excerpt It's the most wonderful time of the year - Christmas Advent of Code time! Advent of Code is an Advent Calendar style series of programming puzzles put out each year, starting on December 1st leading up to Christmas. The puzzles are super festive and ramp up in difficulty over the course of the month. Programmers of every level can participate, and in researching some of the more difficult problems you'll probably learn something cool! It's a great way to finish out the year. I've been taking part in Advent of Code since 2019 (I've never completed a full year - and that's ok! You can participate for as long as it's fun and have the time) and have tried solving in multiple different languages - Advent is a great way to learn/skill up in a new language. But Ruby remains my favorite language in which to solve these puzzles. Many of Ruby's strengths - its flexibility, robust standard library, and tooling make it the ideal language for Advent of Code. Flexibility Ruby doesn't enforce any one way of writing code. Want to solve a problem with a procedural script? Go for it! Want to leverage object-oriented programming and send messages between classes? Can do! Want to write in a functional style and map and zip a data structure in one long chain? You can do that too! And you can mix and match paradigms between problems - whatever models each problem best. Ruby's data structures are super flexible as well. In many of the problems, Array and Hash allow you to very quickly model solutions. But if you find a hash isn't quite cutting it and you don't want to upgrade it to a full class, you can use the Data class to create value objects. This will lend you a bit more structure than a hash, and allow you to encapsulate some logic inside it without having to bring in the overhead of a Class. Some of Ruby's flexibility - metaprogramming in particular - can be...unpopular... in larger production codebases. It's the "magic" that can lead to some nasty bugs. But Advent is a great place ## Announcing the Square Go SDK DevFeed: [Announcing the Square Go SDK]() Original publisher: [Read original article]() Author: Jordan Bergero Published: 2024-12-18T17:00:00Z Content type: release Language: en Sources: [Square Corner Blog RSS Feed]() Topics: [SDKs](), [Go Language](), [Back end](), [API]() Tags: [api](), [apis](), [backend](), [dependency](), [go](), [guide](), [retry](), [sdk](), [sdks](), [standard-library]() ### AI overview Square announces a Go SDK for building Square integrations with Go backends.

Binary Search Clip, Clone, and Compact Compare Contains, Delete, and Equal Introduction In the first post of this series, I discussed the binary search API from the slices package that is now part of the standard library with the release of version 1.21. In this post, I will share how the Clip, Clone, and Compact APIs work. Clip The Clip API can be used to remove unused capacity from a slice. This means reducing the capacity of the slice to match its length. ## The C Standard Library Function isspace() Depends on Locale DevFeed: [The C Standard Library Function isspace() Depends on Locale]() Original publisher: [Read original article]() Published: 2023-06-06T13:41:23Z Content type: article Language: en Sources: [Evan Jones]() Topics: [C](), [ASCII](), [bug](), [Library]() Tags: [ascii](), [bug](), [c](), [function](), [implementation](), [library](), [locale](), [mac](), [mac-os](), [standard](), [standard-library]() ### AI overview The article explains that C's isspace() behavior depends on the active locale. In the default C locale it recognizes six ASCII whitespace characters, while other locales may also recognize Unicode whitespace. The author connects this behavior to a parsing bug involving PostgreSQL Hstore values on Mac OS X. ### Source excerpt This is a post for myself, because I wasted a lot of time understanding this bug, and I want to be able to remember it in the future. I expect close to zero others to be interested. The C standard library function isspace() returns a non-zero value (true) for the six "standard" ASCII white-space characters ('\t', '\n', '\v', '\f', '\r', ' '), and any locale-specific characters. By default, a program starts in the "C" locale, which will only return true for the six ASCII white-space characters. However, if the program changes locales, it can return true for other values. As a result, unless you really understand locales, you should use your own version of this function, or ICU4C's u_isspace() function. An implementation of isspace() for ASCII is one line: /* Returns true for the 6 ASCII white-space characters: \t \n \v \f \r ' '. */ int isspace_ascii(int c) { return c == '\t' || c == '\n' || c == '\v' || c == '\f' || c == '\r' || c == ' '; } I ran into this because On Mac OS X, Postgres switches to the system's default locale, which is something that uses UTF-8 (e.g. en_US.UTF-8, fr_CA.UTF-8, etc). In this case, isspace() returns true for Unicode white-space values, which includes 0x85 = NEL = Next Line, and 0xA0 = NBSP = No-Break Space. This caused a bug in parsing Postgres Hstore values that use Unicode. I have attempted to submit a patch to fix this (mailing list post, commitfest entry). For a program to demonstrate the behaviour on different systems, see isspace_locale on Github. ## Map as a property delegate DevFeed: [Map as a property delegate]() Original publisher: [Read original article]() Published: 2023-05-08T00:15:00Z Content type: tutorial Language: en Sources: [Kt.

It also discusses the desired properties of a hashing function and the role of cryptographic signatures and public-key recovery in a decentralized blockchain. ### Source excerpt Introduction In episode 11, Bill highlighted the issue of identity verification and provided a solution to this problem. The solution proposed was to cryptographically sign a transaction to verify its authenticity. Bill chose to implement a solution making use of the Elliptic Curve Digital Signature Algorithm (ECDSA) as the public key can be extracted from a signature. Although a small distinction, the ability to re-compute a public key is essential in a decentralized and distributed environment. ## Ultimate Go: Advanced Engineering Episode 9 DevFeed: [Ultimate Go: Advanced Engineering Episode 9]() Original publisher: [Read original article]() Published: 2022-12-20T00:00:00Z Content type: tutorial Language: en Sources: [William Kennedy]() Topics: [Blockchain](), [Go Language](), [Bitcoin](), [Ethereum]() Tags: [bitcoin](), [blockchain](), [blockchain-asset](), [build](), [building](), [code](), [concepts](), [engineering](), [ethereum](), [genesis](), [genesis-json](), [genesis-record](), [go](), [go-blockchain](), [implement](), [introduction](), [project](), [project-layout](), [reuse](), [standard-library]() ### AI overview This video tutorial covers the initial layout of a blockchain project in Go, including creating a genesis record and explaining its role. It also introduces fundamental blockchain verifications. ### Source excerpt Introduction In episode 8, Bill wanted to build a blockchain in Go and began to lay the groundwork for the project. Go is a good choice because its standard library has the necessary network and cryptographical functionality required to build a blockchain. Unlike the previous segment, Bill plans to use this blockchain to manage accounts and balances with hypothetical assets. Bill will reuse concepts from ethereum, bitcoin and the previous segment of the series to implement this blockchain. ## Building a Semantically Correct Blockchain in Go: Genesis Blocks and Asset On-Ramping DevFeed: [Building a Semantically Correct Blockchain in Go: Genesis Blocks and Asset On-Ramping]() Original publisher: [Read original article]() Published: 2022-12-19T00:00:00Z Content type: tutorial Language: en Sources: [William Kennedy]() Topics: [Go Language](), [Blockchain](), [Dependency management](), [Library]() Tags: [blockchain](), [blockchain-asset](), [blockchain-equity](), [dependency-management](), [ethereum](), [genesis](), [genesis-block](), [go](), [go-blockchain](), [standard-library](), [video]() ### AI overview This video explains how to build a semantically correct blockchain entirely with Go. It covers how a blockchain starts, the role of the genesis block, and how assets are introduced into the blockchain, while building on concepts from an earlier dependency-management example. ### Source excerpt Introduction In the first part of the series, Bill designed a dependency management system. The dependency manager needed to be distributed, transparent, cryptographically auditable and scalable. To meet these requirements, Bill borrowed concepts from blockchain. He did this to illustrate how the blockchain can be repurposed and used to accomplish the mundane task of dependency management. While doing so, Bill indirectly highlighted the problems a blockchain solves. In the next segment of the series, Bill will build a semantically correct blockchain. He plans to perform this task entirely with Go and he'lll re-use the ideas described in the previous segment to further facilitate your understanding of what a blockchain is. Early on Bill admits he is no economist, and for the sake of the series he will use a hypothetical pot of gold as the starting equity for his blockchain. Follow along and learn how assets are "on-ramped" into the blockchain. ## Scope functions DevFeed: [Scope functions]() Original publisher: [Read original article]() Published: 2022-09-23T00:05:00Z Content type: tutorial Language: en Sources: [Kt.
