The ISP Column A column on things Internet Other Formats: The Size of Packets October 2024 Geoff Huston We've now been running packet-switched networks for many decades, and these days it's packets and not virtual circuits lie behind most of the world's digital communications service. But some very fundamental questions remain unanswered in this packet-switched world. Perhaps the most basic questions is: "How big should a packet be?" And, surprisingly enough, there is no clear answer!

Fun with -fsanitize=undefined and Picolibc Both GCC and Clang support the -fsanitize=undefined flag which instruments the generated code to detect places where the program wanders into parts of the C language specification which are either undefined or implementation defined. Many of these are also common programming errors. It would be great if there were sanitizers for other easily detected bugs, but for now, at least the undefined sanitizer does catch several useful problems. Supporting the

The HTML spec used to define an outline algorithm that gave <h1> elements an implicit semantic heading level based on how many sectioning elements ( <section> , <aside> , <nav> , and <article> ) it was nested inside. The browser rendering was such that section > h1 would have the same font-size and margin as <h2> . The section > section > h1 would be represented as <h3> , and so on. The default rendering was implemented in browsers in their UA styles, but not the heading level in the accessibil

Introduction One of the key insights from queuing theory is that the average queue size for an unbounded system tends to increase significantly as utilization approaches 100%. Theoretical models show no bound to this increase and at 100% utilization the resulting average queue size grows toward infinity. This is important because queues themselves consume resources, be it memory or disk space on a computer or factory floor space in a plant. In an ideal world, we wouldn’t need queues. Who likes

Cache-aware programming can make a huge performance difference, especially when writing code in C++ or Rust. Python is a much more high-level language, and doesn't give us that level of control over memory layout of our data structures. So does this mean that CPU caching effects aren't relevant in Python? In this post, we'll conduct some basic experiments to answer this question, by accessing list element either in sequental order or in a random order. Results indicate that randomized access i

vramfs Unused RAM is wasted RAM, so why not put some of that VRAM in your graphics card to work? vramfs is a utility that uses the FUSE library to create a file system in VRAM. The idea is pretty much the same as a ramdisk, except that it uses the video RAM of a discrete graphics card to store files. It is not intented for serious use, but it does actually work fairly well, especially since consumer GPUs with 4GB or more VRAM are now available. On the developer's system, the continuous read p

The Biology of B-Movie Monsters BY | SESSION : Biology and Geometry Collide! Size has been one of the most popular themes in monster movies, especially those from my favorite era, the 1950s. The premise is invariably to take something out of its usual context--make people small or something else (gorillas, grasshoppers, amoebae, etc.) large--and then play with the consequences. However, Hollywood's approach to the concept has been, from a biologist's perspective, hopelessly naïve. Absolute

Edgar Cervantes / Android Authority TL;DR Google is making it easier to uniformly resize objects in Google Slides. You can now select and resize multiple objects and scale your selection proportionally. Google has also simplified selecting specific objects in slides with multiple layered objects. Google is rolling out some quality-of-life improvements that should greatly improve how you select and resize objects in Google Slides. The changes aim to help users easily resize objects uniformly

What is Package Phobia? Package Phobia reports the size of an npm package before you install it. This is useful for inspecting potential dependencies or devDependencies without using up precious disk space or waiting minutes for npm install . What is "publish size" vs "install size"? The "publish size" is the size of the source code published to npm. This number is easy to detect and is typically very small. The "install size" is the size your hard drive will report after running npm instal

One of the most annoying things about programming in C is the lack of support for generic types, also known as parametric polymorphism. Not to be confused with the abomination that is _Generic. I wish C had something like the following: struct Vector<T> { T* data; size_t capacity; size_t length; }; void vector_resize<T>(Vector<T>* v, size_t capacity) { v->data = realloc(v->data, capacity * sizeof(T)); v->capacity = capacity; } void vector_append<T>(Vector<T>* v, T element) { if (v->length >= v

Texas Instruments says it has shrunk the size of the smallest microcontroller unit in its industry with a new MCU the size of a black pepper flake. The MCU packaging is only 1.38 square millimeters in size and is part of the company's Arm Cortex line of embedded designs. TI says the product is aimed at small products including medical wearables, earbuds, stylus pens and electric toothbrushes. The product includes a 12-bit analog-to-digital converter and has 16KB of flash memory and 1KB of SRAM

Building on my previous post on sorting algorithms, I implemented the same algorithms using CUDA to explore performance improvements through parallel computing. The goal is to see how we can leverage the power of parallel computing to speed up our sorting algorithms. I went for a NVIDIA recruiting event some days ago, that was a great event and it motivated me to try to rewrite the sorting algorithms using CUDA. I’ll take merge sort as our test algorithm because it nicely divides the problem in
