Intel AVX2 is one of the most important SIMD extensions in the x86 instruction set. While the original AVX instruction set introduced 256-bit YMM registers and wider floating-point vector operations, AVX2 extended that model to integer SIMD and made 256-bit vector programming much more broadly useful. AVX2 arrived with Intel’s…
Intel AVX, short for Advanced Vector Extensions, marked one of the most important transitions in the history of x86 SIMD programming. It extended the 128-bit SSE model to 256-bit vector registers, introduced a cleaner instruction encoding, and made SIMD code easier for compilers and developers to optimize. AVX was first…
SSE4.2 is the second part of Intel’s SSE4 family. Compared with SSE4.1, it is much smaller and more specialized. SSE4.1 added a broad set of practical SIMD improvements: blends, dot products, rounding, integer min/max operations, widening conversions, insertion and extraction, and several multimedia helpers. SSE4.2 did not continue in that…
SSE4.1 is one of the most useful refinement steps in the SSE family. It did not introduce wider vectors, new XMM registers, or the newer AVX encoding model. Instead, it filled many gaps that made SSE2, SSE3, and SSSE3 code awkward. Where SSE3 mostly improved floating-point horizontal operations, and SSSE3…
SSSE3 is one of the most useful but most poorly named SIMD extensions in the x86 family. The name stands for Supplemental Streaming SIMD Extensions 3, and the extra “S” is important. SSSE3 is not the same thing as SSE3. It is a later extension, with a very different focus.…
SSE3 is one of the easiest SIMD instruction sets to misunderstand. Compared with MMX, SSE, and SSE2, it did not introduce a new vector register file, it did not widen vectors beyond 128 bits, and it did not radically change the programming model. Instead, SSE3 added a small set of…
Standing out of the pack starts by being visible, and being noticed by the right group of professionals. No matter how good your profile is, it is lost in a sea of similar profiles, so you need to show up and start attracting visits to your profile page. Suppose we…
Scraping content from websites can be a useful tool for gathering information or automating certain tasks. In C#, there are several libraries available that can help make this process easier. In this blog post, we will cover how to use the HtmlAgilityPack library to scrape content from websites in C#.…
Scraping dynamic content from websites has become an important task in data collection and analysis. With the advancements in web technologies, websites are now using dynamic content that cannot be easily scraped with traditional web scraping techniques. In this blog post, we will explore how to scrape dynamic content from…
File I/O looks like one of those things that cannot be unit-tested properly. A method that reads directories, scans files, compares extensions, and deletes files seems tied to the real machine where the test is running. That creates all the usual problems: tests become slow, fragile, dependent on local paths,…
