Image credit: Brett Sayles via Pexels It is a truth universally acknowledged in the tech world that if you build a self-driving car in your garage, the universe will test your code in the most comically unforgiving way possible. Case in point: a viral video circulating out of Pakistan, where a hopeful innovator’s DIY autonomous vehicle skipped the gentle test-track phase and opted instead to target a parked police van with surgical, irony-laced precision. A Demonstration Gone Spectacularly Wrong The clip begins like many hopeful tech demos on the internet. A creator enthusiastically showcases a vehicle modified to steer itself, promising a glimpse into the future of automated transit. But much like trying to perform data science in R when you could be using the sheer perfection of Python, the execution devolved into unnecessary pain very quickly. The vehicle suddenly veered off its path, ignored the open street entirely, and slammed directly into a stationary police cruise...

Image credit: Rickie-Tom Schünemann via Pexels Xiaomi's performance-focused sub-brand POCO is set to disrupt the mid-range smartphone arena once again with the global debut of the POCO F9 Pro and the flagship-tier POCO F9 Ultra later today. Known for pushing the boundaries of price-to-performance ratios, POCO's latest F-series entry promises to bring enthusiast-grade features to a much broader audience. Next-Gen Display Technology and Performance The standout feature generating massive buzz ahead of the official keynote is the device's screen technology. Leaks suggest the POCO F9 Pro could debut a groundbreaking 185Hz refresh rate display, setting a new benchmark for ultra-smooth mobile gaming and fluid interface navigation. If accurate, this ultra-high refresh rate would propel the device well past standard 120Hz and 144Hz competition in the mid-range market segment. Under the hood, the smartphone is expected to feature a capable, high-efficiency chipset pai...

Analogies are rhetorical devices or stylistic devices used in dialogue or narrative to express a complex topic in a familiar context and simplify the underlying concept in its form – well, that sounds very much like the task of numerics as a field of mathematics. Life can have different viewpoints Numerical analysis is certainly not just a stylistic device or something that can be applied quickly. However, it is important to bear in mind the parallels here: when using analogies and numerical analysis, the task is to express a complex abstract construct in a more comprehensible or clearer form and to master interaction with the situation. Etymology The word analogy comes from the Latin word "analogia", which translates as "correspondence" or "relationship". An analytical abstraction of a topic in the context of semantics that can be projected onto more everyday areas of life. The prefix "ana-", also from Latin, has many meanings: up/on back/again ...

Indifference...causes a lot of problems but also offeres a lot of opportunities, but are they worth it? This article is slightly different in nature, as it aims to abstract the influences of today's technology on society. What I say here is expressed more with the intention of at least trying to make a difference. Illustration: What we see, is not always correct nor sharp It is hard to imagine everyday life without the media presence we have today; we are constantly surrounded by it. Everyday life is becoming more hectic, non-stop, and always geared toward optimization, regardless of any short- or long-term setbacks.  This bombardment of media can quickly become overwhelming and tempt us to approach the media selectively or not at all, indulging in (selective) ignorance. Occasionally, during periods when one needs peace and quiet, or perhaps during vacations, this may be helpful. However, one might consider that if one only allowed oneself this during vacations, as in the past, the...

Performance – how fast a program runs – matters a great deal in computing. In tasks like heavy numerical simulation, processing large files, or running many concurrent operations, a few extra seconds (or minutes) can make a big difference. At one end of the spectrum are low-level compiled languages like C++ that give programmers direct control of the hardware, and at the other end are high-level languages like Python that prioritize ease of use but may incur overhead. Java sits in the middle as a managed language with a sophisticated runtime, while Julia is a newer language explicitly designed for scientific and numerical computing with high performance in mind. In this article, we compare how Python, C++, Java, and Julia typically perform on three kinds of tasks – numerical computation, file I/O, and concurrency – and explain what language features and architectures cause the differences. Illustration: The speed of code Numerical Computation Python: Pure Python code (e...

Images now make up nearly 50% of a typical website's total page weight . In an era where both  user experience and search engine rankings are tied to page speed , optimizing images is no longer a luxury—it's a necessity. This article will guide you through two powerful techniques to address this: implementing responsive images with srcset and converting your entire library to the modern WebP format . Illustration: A webP image Why Your Website Needs Responsive Images The "one-size-fits-all" approach to images is broken. Serving a massive, high-resolution desktop image to a mobile user wastes bandwidth and slows loading times . Conversely, stretching a small image on a high-resolution screen makes it look blurry or pixelated . Responsive image technologies solve two main problems: The Art Direction Problem : Delivering a differently cropped or composed image depending on the display size. For example, a wide header image on desktop might be cropp...

Want to glue Python to the rest of your system  -  call a compiled program, run a shell script, invoke Node.js, call Java, or pipe data to/from R? Enter subprocess . It’s Python’s standard way to start external programs, control their input/output, check return codes, set environments and timeouts — all with a solid API. Below is a practical, friendly guide: what subprocess is, why you’d use it, examples, best practices, pitfalls, and which languages/tools you can call from it. What is subprocess ? subprocess is a standard Python module that lets your Python program spawn new processes, connect to their input/output/error pipes, and obtain their return codes. It replaces older modules like os.system , popen and friends with a unified, safer interface. Key high-level primitives: subprocess.run() — simple, recommended for most cases (Python 3.5+). subprocess.Popen — lower-level, use when you need streaming IO, advanced control, or long-lived processes...
