SDS: Simple Dynamic Strings library for C

Simple Dynamic Strings Notes about version 2: this is an updated version of SDS in an attempt to finally unify Redis, Disque, Hiredis, and the stand alone SDS versions. This version is NOT binary compatible* with SDS verison 1, but the API is 99% compatible so switching to the new lib should be trivial. Note that this version of SDS may be a slower with certain workloads, but uses less memory compared to V1 since header size is dynamic and depends to the string to alloc. Moreover it includes

FEMA Staffers Warned of Looming ‘Katrina-Level’ Disaster, Then Got Suspended

It’s been 20 years since Hurricane Katrina slammed into the U.S. Gulf Coast, killing nearly 1,400 people and displacing up to 1.2 million more. The storm’s impact overwhelmed the Federal Emergency Management Agency, revealing fatal flaws in its disaster response. The agency’s failure prompted Congress to overhaul FEMA largely through the ​​Post-Katrina Emergency Management Reform Act (PKEMRA). This set higher expectations for its leaders and enhanced its autonomy within the Department of Homela

We rebuilt Cloud Life's infrastructure delivery with System Initiative

By Ryan Ryke, CEO, Cloud Life ‍ This is the story of how we eliminated static configuration files from our infrastructure workflows at Cloud Life, and, in the process, cut delivery times by more than half, improved reliability, and made our engineers’ work feel much smoother and more manageable. Before this project, we’d been working with the same model that most modern infrastructure teams use: Terraform scripts, config repos, PR reviews, CI pipelines. We’d optimized what we could, but the w

How to slow down a program and why it can be useful

Most research on programming language performance asks a variation of a single question: how can we make some specific program faster? Sometimes we may even investigate how we can use less memory. This means a lot of research focuses solely on reducing the amount of resources needed to achieve some computational goal. So, why on earth might we be interested in slowing down programs then? Slowing Down Programs is Surprisingly Useful! Making programs slower can be useful to find race conditions

We Rebuilt Cloud Life's Infrastructure Delivery with System Initiative

Posts from this author will be added to your daily email digest and your homepage feed. Disney is suing Sling TV over its new streaming passes that give you access to live cable networks for as little as one day. The lawsuit, filed under seal, claims Sling violated the terms of its licensing agreement with Disney and included its networks in the sh

Computing’s Top 30: Theofanis Raptis

Transitioning between two different cultures and professional roles—from working at a university in Greece to joining the National Research Council of Italy—presented Theofanis Raptis with several valuable lessons, including an understanding of what he calls an intellectual “fermentation” process. Triggered by internationalization, bilateral cooperation, and cross-discipline collaborations, this fermentation included the dynamic exchange and blending of ideas across disciplines and cultures, le

The first stars may not have been as uniformly massive as we thought

For decades, astronomers have wondered what the very first stars in the universe were like. These stars formed new chemical elements, which enriched the universe and allowed the next generations of stars to form the first planets. The first stars were initially composed of pure hydrogen and helium, and they were massive—hundreds to thousands of times the mass of the Sun and millions of times more luminous. Their short lives ended in enormous explosions called supernovae, so they had neither the

The “Wow!” signal was likely from extraterrestrial source, and more powerful

A new study has re-examined the famous "Wow!" signal, finding that it likely has an extraterrestrial origin after all, and may have been even more intense than previously believed.

Object-oriented design patterns in C and kernel development

My scheduler operations implementation A benefit of working on your own operating system is that you’re free from the usual "restraints" of collaboration and real applications. That has always been a major factor in my interest in osdev. You don’t have to worry about releasing your program, or about critical security vulnerabilities, or about hundreds of people having to maintain your code. A benefit of working on your own operating system is that you’re free from the usual "restraints" of co

This Visiting Interstellar Comet Just Keeps Getting Weirder

Ever since interstellar comet 3I/ATLAS whizzed into our cosmic neighborhood in July, astronomers have been racing to uncover its characteristics. Now that the powerful James Webb Space Telescope has taken a good look at this icy interloper, it seems to be weirder than anyone imagined. A preprint submitted to the Astrophysical Journal Letters for peer review on Monday, August 25, describes the first results from JWST’s survey of 3I/ATLAS. A team of astronomers observed the comet with the telesc

Das Problem mit German Strings

German strings are everywhere I look. The impression I’ve gotten from working in the Rust Arrow/Datafusion ecosystem and related file formats for the last couple of months is that StringViews (the implementation of German strings in Arrow) are becoming, if they have not already, the canonical form of representing string columns at execution time. This is generally a good idea. German strings are a fantastic innovation rooted in simplicity that greatly improves most string processing use-cases i

Gmail may finally alert you when someone reacts to your Chat messages (APK teardown)

Tushar Mehta / Android Authority TL;DR Strings in the latest Gmail update hint at some new Google Chat features in testing. Notification summaries in Gmail might work independently of Android 16’s system-wide version, bringing the feature to more devices. Gmail may also offer auto-generated conversation summaries and finally notify you when someone reacts to your Chat messages. Little by little, Gmail is slowly turning into more of a one-stop hub than an inbox. Google has been weaving Chat i

Marshall's first party speaker unsurprisingly looks like a guitar amp

Marshall just introduced its very first party speaker, the Bromley 750. It looks a whole lot like a guitar amp, which makes sense given the company's pedigree. Also, instrument amps are basically just big speakers anyways. This Bluetooth speaker includes a replaceable battery that allows for more than 40 hours of use before requiring a charge. It produces 360-degree stereophonic sound that Marshall says will "find its way through any crowd." It also features a "sound character knob" that change

Health Connect prepares to track your favorite vices (APK teardown)

Mishaal Rahman / Android Authority TL;DR Health Connect gives Android users a tool to store their health and fitness data in a centralized repository. In addition to regular health metrics, Health Connect is getting ready to keep track of nicotine and alcohol consumption. Nicotine reporting will support different consumption methods, like cigarettes and vaping. Let’s be honest: Android Health Connect needs work. The system has the best of intentions, offering a tool for organizing and making

CEO Demands Employees Start Using AI, Fires Anyone Who Doesn't

Almost three years since the release of OpenAI's explosively popular ChatGPT, it's clear that artificial intelligence isn't exactly taking the job market by storm. Sure, AI makes a convenient cover for business executives who were already looking to downsize or outsource their labor force, but the tech's myriad hallucination issues, legal risks, and security baggage make it ill-suited to automate human jobs. That's to say nothing of the fact that 95 percent of businesses gunning for an AI overh

Anonymous structavaganza in Zig

Mon Aug 25 2025 When statements disappear, what remains of good semantics? Let’s see what side effects have been introduced! To start, observe this truly primordial ‘C code; struct A {}; struct B {}; void example ( struct A e ); int main (){ example (( struct B){}); } clang output: error: passing 'struct B' to parameter of incompatible type 'struct A' example((struct B ){}); ^~~~~~~~~~~~ THE TYPES ARE UNIQUE. THEY HAVE DIFFERENT NAMES! THE ARE NOMINALLY DIFFERENT. And such it is for all

Silicon Valley is pouring millions into pro-AI PACs to sway midterms

In Brief Andreessen Horowitz and OpenAI President Greg Brockman are among the Silicon Valley veterans putting more than $100 million into a network of political action committees (PACs) that will advocate against strict AI regulations in next year’s midterm elections, reports The Wall Street Journal. The new pro-AI super-PAC network dubbed “Leading the Future” aims to use campaign donations and digital ads to advocate for favorable AI regulation and oppose candidates that the group thinks will

Tech’s Heavy Hitters Are Spending Big to Ensure a Pro-AI Congress

Much of the American public is dubious to neutral when it comes to artificial intelligence. A recent poll found that 71 percent of Americans were concerned about the technology “permanently” displacing human workers. Since we ostensibly live in a democracy, you’d think that would be bad news for the AI industry; unfortunately, many of the folks who are central to our economy are all-in. What do you do when you can’t win in the court of public opinion? The next best thing is to work the refs, a

Memory optimizations to reduce CPU costs

Imagine that you are given the following task, with a file like this: Name,Department,Salary,JoinDate John Smith,Marketing,75000,2023-01-15 Alice Johnson,Finance,82000,2022-06-22 Bob Lee,Sales,68000,2024-03-10 Emma Davis,HR,71000,2021-09-01 You want to turn that into a single list of all the terms in the (potentially very large) file. In other words, you want to turn it into something like this: [ { "term" : "Name" , "position" : 0 , "length" : 4 } , { "term" : "Department" , "position" : 5

The Google TV Streamer is rarely on sale, so it’s your lucky day!

My 4 favorite Linux distros for streaming - and why choosing the right one makes a huge difference

Jose A. Bernat Bacete / Moment via Getty Follow ZDNET: Add us as a preferred source on Google. ZDNET's key takeaways Some Linux distributions are better for streaming. There are certain factors to consider for streaming on Linux. The distributions here should work fine without tweaking. Among Spotify, Netflix, Hulu, and other streaming services, I consume a lot of content. Although you might think any operating system with a web browser (or the ability to install an app or two) is perfectl

Google to require developer verification for Android apps outside the Play Store

Google is tightening security measures around Android app distribution, the company announced on Monday. Starting next year, Google will begin to verify the identities of developers distributing their apps on Android devices, not just those who distribute via the Play Store. The changes will affect all certified Android devices once live, though the global rollout will be more gradual. The tech giant stresses that this does not mean developers can’t distribute outside of the Play Store through
