Web developers often face the challenge of compressing images to meet specific size requirements, such as a 100KB limit for uploads. The traditional approach involves manually adjusting image quality settings through trial and error, which is inefficient and unreliable. This article introduces a more effective method using binary search to precisely compress images to a target size. The author explains that the quality slider commonly used in image compression tools is a poor primitive because the same quality setting produces vastly different file sizes depending on the image content. Instead, the target-first approach focuses on the desired file size (e.g., 100KB) and finds the highest quality that fits within that budget. The technique involves drawing the image to a canvas, then performing a binary search over the quality axis (typically 8 iterations) to find the optimal quality setting. The algorithm ensures that the resulting image is as high quality as possible while staying within the size limit. The author provides a JavaScript function that implements this method, which can be used directly in web applications. Additionally, the author created a free browser-based tool called 'Compress Image to 100KB' that automates this process, allowing users to drop in an image and get a compressed version that fits their size requirements without any guesswork. The tool operates entirely in the browser, ensuring privacy as images are never uploaded to a server. The article concludes by asking readers about their own image compression practices, including target sizes and whether they compress at upload time, build time, or via a CDN. This method represents a shift from the common practice of compressing defensively (using lower quality settings to ensure size limits are met) to a more precise and efficient approach that maximizes image quality within constraints.

In #45955 I proposed a new slices package in the standard library. After considerable discussion there and in discussion #47203 we settled on an API and added the experimental package golang.org/x/...

(Relevant article based on post: Optimizing Dropdown Menus for Better UX in Web Applications) You Should Know: When dealing with large dropdown menus (like country lists), inefficient search mechanisms can frustrate users. Instead of manual iteration, implement binary search for faster lookups. Below are practical steps and commands to optimize UX in web apps. 1. Binary Search Implementation (JavaScript) function binarySearch(arr, target) {

There are two ways to search an element in a List class, by using contains() method or by using Collections.binarySearch() method. There are two versions of binarySearch() method, one which takes a List and Comparator and other which takes a List and Comparable. This method searches the specified list for the specified object using the binary search algorithm. The list must be sorted into ascending order according to the natural ordering of its elements (as by the sort(List) method) prior to making this call. If List is not sorted, then results are undefined. If the List contains multiple elements equal to the specified object, there is no guarantee which one will be returned. This method runs in log(n) time for a "random access" list (which provides near-constant-time positional access). --- Java, Unix, Tibco RV and FIX Protocol Tutorial
