It preserves TIN's search features and correctness but uses full table scans, making it much slower and suitable for small test datasets rather than production workloads. ### Source excerpt Lead is a feature-equivalent version of TIN you can run in CI ## Lookat 2.1.0 released DevFeed: [Lookat 2.1.0 released]() Original publisher: [Read original article]() Author: Staf Wagemakers Published: 2025-09-14T18:04:00Z Content type: release Language: en Sources: [stafwag Blog]() Topics: [Unix](), [color](), [browser](), [changelog]() Tags: [2](), [2025](), [ansi](), [browser](), [bsd](), [changelog](), [color](), [freebsd](), [git](), [linux](), [lookat](), [manpage](), [ncurses](), [netbsd](), [openbsd](), [release](), [unix]() ### AI overview Lookat/Bekijk 2.1.0 is the latest stable release of a Unix file browser and viewer that supports colored man pages.

Usually, it is to get the user's attention and signalize success or error. I could reach for a battle-tested library like Chalk, but I usually don't need all of its features. Instead, I have a tiny script I copy from project to project: const reset = "\x1b[0m"; const log = { green: (text) => console.log("\x1b[32m" + text + reset), red: (text) => console.log("\x1b[31m" + text + reset), blue: (text) => console.log("\x1b[34m" + text + reset), yellow: (text) => console.log("\x1b[33m" + text + reset), }; Then, I can easily log things in color: log.green("This seems like a very successful message"); log.red("Something might have gone wrong"); log.blue("I'm here to inform you of something"); log.yellow("Lemon 🍋"); Once executed, it looks like this: How it works # The script uses something called ANSI escape codes. It is a way to give commands to a terminal by passing sequences of bytes, usually starting with an ASCII escape character \x1b. They are mostly used to move the cursor and to change the color or styling of the text. They are standardized, and they should work on any platform. For example, \x1b[31m is an escape sequence that tells our terminal to switch color to red. All text after it will be red, until we pass the reset sequence \x1b[0m, which will revert text to the default color. More robust version # If you need more features, I suggest using an existing library. I usually recommend picking one of these two: picocolors - when I need more robust but still lightweight library Chalk - when I need a fully featured coloring library Browser # As a bonus, let's see how we can use color in a browser's console. Escape sequences are not going to work, but we can actually use CSS. console.log("%c🍋 Lemon", "background: black; color: yellow;"); Everything after %c will be styled using CSS defined in the parameter after it. Open the console in your browser and click on the b ## Hardware entropy: RDRAND DevFeed: [Hardware entropy: RDRAND]() Original publisher: [Read original article]() Author: Marek Published: 2013-03-24T23:00:00Z Content type: article Language: en Sources: [Marek Majkowski]() Topics: [Randomizer](), [Hardware](), [cpu](), [Security](), [intel](), [Linux Kernel]() Tags: [aes](), [ansi](), [bits](), [cryptographic](), [entropy](), [fips](), [generator](), [hardware](), [intel](), [kernel](), [linux-kernel](), [nist](), [security](), [time]() ### AI overview This article explains Intel's RDRAND instruction, which uses an on-processor entropy source and AES conditioning to produce hardware-generated random numbers. It also describes checking the carry flag because RDRAND may temporarily return no data when demand exceeds hardware supply. ### Source excerpt Hardware entropy: RDRAND This is the third blog post on machine instructions: This time I've noticed instruction. According to Wikipedia is: ... a random number generator that is compliant with security and cryptographic standards such as NIST SP800-90, FIPS 140-2, and ANSI X9.82. The generator uses an on-processor entropy source, which passes the randomly generated bits to an AES (in CBC-MAC mode) conditioner to distill the entropy into non-deterministic random numbers. Sounds good. ## Pretty command line / console output on Unix in Python and Go Lang DevFeed: [Pretty command line / console output on Unix in Python and Go Lang]() Original publisher: [Read original article]() Author: Graham King Published: 2011-11-16T01:17:10Z Content type: tutorial Language: en Sources: [Graham King]() Topics: [Command-line interface](), [console](), [Script](), [Python](), [Unix](), [Go Language](), [screen](), [color]() Tags: [ansi](), [color](), [command-line](), [commandline](), [console](), [go](), [python](), [screen](), [scripts](), [software](), [unix]() ### AI overview A tutorial on improving Unix command-line script output without using curses.
