You reading this tells me you wish to learn more about Excel. This article continues our Excel series, where we explored the VLOOKUP function in the last iteration. The complete VLOOKUP guide demonstrated how the function works and how best to use it. This time, we shall bring the same focus to conditional logic and formulas like the IF function in Excel. The aim is to understand the different types of conditional logics and know how to use their operators in a working function inside Excel. So, no fluff needed here. Let’s simply dive in, starting with what Conditional Logic…
Tare once worked as a plumber in South Africa’s Western Cape and saw limited opportunities for economic advancement. After a chance meeting with a senior leader at the not-for-profit Digital Skills Africa, he received a second-hand laptop and began studying cybersecurity through Cisco Networking Academy. Showing exceptional perseverance, Tare’s studies eventually led him to become a qualified instructor in cybersecurity, Cisco networking, DevNet, and more—transforming his life and inspiring others. On this International Day of Learning, we celebrate the transformative power of education. At Cisco, we believe that learning is the bridge to opportunity. For nearly three decades, the Cisco…
ESET’s Jake Moore used smart glasses, deepfakes and face swaps to ‘hack’ widely-used facial recognition systems – and he’ll demo it all at RSAC 2026 13 Mar 2026 • , 2 min. read Facial recognition is increasingly embedded in everything from airport boarding gates to bank onboarding flows. The widely-held assumption is that a face is hard to fake and that matching a live face to a trusted source is a reliable identity signal. Jake Moore, ESET Global Cybersecurity Advisor, recently put this assumption through several practical stress tests. His experiments showed that the powerful technology can actually be both…
you’re not really sick or injured. You’re just feeling… off. like you should be doing something about it, but can’t quite put your finger on what’s going on. Your shoulders are always tight. You snap at people in a split second – its a bad habit that’s developed over time. You lie in bed feeling exhausted but can’t wind down, then wake up the next morning feeling like you never actually got any rest. At some point, that can just start to become normal, and thats not normal at all. Stress isnt all about feeling anxious or worried. It can…
For most of its existence, the IoT device has had one job: collect data and send it somewhere else to be understood. That model is under pressure from two directions at once, and the response from the industry is becoming hard to ignore. Edge AI IoT devices–ones that process and act on data locally rather than routing it to the cloud–are moving from pilot programmes into mainstream product portfolios in 2026. The timing is not accidental.Cloud-dependent IoT has a cost problem that is getting worse. The global memory shortage, driven by AI data centres consuming an unprecedented share of DRAM and NAND production, has pushed component prices to…
The Samsung Galaxy A57 is coming very soon. It was listed, by mistake, this week by a European retailer. It’s expected to have a 6.6-inch FHD+ Super AMOLED, an Exynos 1680 SoC, 6/8/12GB of RAM, 128/256GB of storage, a 50MP main, a 12MP ultrawide, and a 5MP macro camera, a 12MP selfie, and a 5,000mAh battery. Samsung SDI has been testing 12,000mAh, 18,000mAh, and 20,000mAh Silicon-Carbon batteries – internal test reports have leaked on X, and they show that the company still has work to do. There is no info on the 20,000mAh battery, but the reports for the other…
Ultrathin, stretchable, and 3D-printable nanotube composites can shield electronics from both electromagnetic interference (EMI) and neutron radiation in extreme environments. Study: Ultrathin, Stretchable, and 3D-Printable Complementary Nanotubes–Polymer Composites for Multimodal Radiation Shielding in Extreme Environments. Image Credit: Wanut Sawangwong/Shutterstock.com In a study published in Advanced Materials, researchers combined single-walled carbon nanotubes (SWCNTs) with boron nitride nanotubes (BNNTs) to create a lightweight shielding system with two complementary roles: SWCNTs suppress electromagnetic interference, while BNNTs absorb neutrons. The team first demonstrated the concept in ultrathin hybrid nanotube films, then extended it into a stretchable, 3D-printable polymer composite. The work points to a…

Summary created by Smart Answers AIIn summary:Tech Advisor reports that Google is implementing Automatic Feedback-Directed Optimisation (AutoFDO) to enhance Android’s core operating system performance across smartphones.Initial Pixel phone tests show promising results with 4% faster cold app launches, 1% quicker boot times, and improved battery life through optimized code prioritization.Google plans to expand AutoFDO beyond kernels to other OS aspects, potentially benefiting all Android device manufacturers with snappier interfaces and better responsiveness. Google has confirmed that it’s working to optimise its mobile OS, potentially bringing about a performance upgrade for all Android smartphone users. Over on the official Android Developers…
The Strait of Hormuz is a crucial artery, not only for the transit of oil and cargo but also for the data flowing through submarine cables on the seafloor. Given recent hostilities, which have included damage to data centers in the UAE and Bahrain, it is worth considering whether the potential risk to telecommunications infrastructure extends to the submarine cables in the region.
