Analyzing the Source Code of UEFI for Intel Galileo by PVS-Studio

Firmware development, even when done not in assembler for exotic architectures but in plain C for i386/amd64, is a pretty tough job, where a single bug can cost too much - up to a major failure of the target hardware platform. So it is just vitally necessary to use various techniques to avoid errors at the earliest firmware development stages.Unfortunately, we can only dream of formal verification or application of MISRA C in case of UEFI firmwares (on the other hand, no one feels like spending a couple of years and 50% of the project budget on firmware development),... read more

DIY: How to do a fiber optic mechanical splicing: steps and tips

Mechanical splicing is the process of precisely aligning two fiber optics together using an alignment device and index matching gel that has a similar refractive index and covers the possible air gaps, helping light travel from one fiber to another with minimal loss and little back reflection. However, they are still two separate optical fibers, which is why this method is considered temporary and is mostly use to rapidly restore short-haul single mode or multimode cables in FTTH installations. How to do it? Mechanical splicing is easy to do if you have all the tools... read more

Intel Core i7 4790K Energy Efficiency

Introduction During the time of the first generation Intel Core i series, Tom's Hardware made an article about finding the most efficient clock speed for Core i5 750 http://www.tomshardware.com/reviews/core-i5-750-efficiency,2500.html and Core i7 920 http://www.tomshardware.com/reviews/overclock-core-i7,2268.html. I got curious as to what is the most efficient clock speed for my Core i7 4790K. Test System [CPU] Intel Core i7 4790K [GPU] Gigabyte GTX 970 mini-ITX [MOB] Gigabyte Z97-D3H (F7 bios) [RAM] G.

The short movie (about 10 minutes long) Big Buck Bunny was encoded from AVI to MP4 using High Profile preset. Video resolution is 1080p. Only the first 2 minutes of the video was encoded to shorten the benchmarking time. Big Buck Bunny is an open movie which was... read more

Regarding CSGO MouseMovementRecorder

Hi, Good morning/Afternoon. A lil background about the topic just to get things clear. This article towards: Old school players who have played enough 1.6 (Competitively, Played Lans (Won titles) etc) and towards the Nerds/Geeks who are expert in this matter. New Players or inexperienced this is not for you. Thanks in advance for the replies. For Trolls: (No, it's not about a bad aim, I've played Lan competitively and my aim is not anywhere around bad). In csgo, (MouseMovementRecorder) will always show green/red colors no matter what kind... read more

Dangerous Things: xNTi NFC Tag Implants

Welcome fellow OCN'ers !   As we all know the NFC technology has come leaps and bounds and is spreading quickly into various different methods of both use and deployment. Most of us know NFC from our usage of contactless payments or for quick information transfer from our mobile phones (Cell phones for the American readers :P). I am sure most of you have seen the NFC posters/stickers that are dotted around information kiosks that allow quick access to that important travel information or V-card like information that allows us to send our contact details. In reality NFC... read more
