In the early eras of web development, developers frequently structured web page layouts using nested HTML <table> elements. While tables provided a quick way to arrange sidebars and banners, they introduced major drawbacks: rigid markup, poor responsiveness on mobile devices, and compromised accessibility for screen readers. Building Semantic, CSS-Driven Layouts The modern approach separates structural HTML markup from visual styling. Rather than using table rows and cells for visual positioning, web designers use semantic container elements (such as <header> , <main> , <section> , and <div> ) styled with CSS rules. Key Advantages of CSS Layout Systems Cleaner Code: Lightweight HTML markup that is easier to maintain and faster to load. Responsive Adaptability: Easy repositioning of elements across mobile, tablet, and desktop screens using media queries. Accessibility: Better document structure for search engine crawlers and screen readers. Flex...

In late September 2015, Indian smartphone manufacturer Micromax unveiled three budget-friendly 4G LTE devices: the Canvas Blaze 4G, Canvas Fire 4G, and Canvas Play 4G. To boost adoption across tier-2 and tier-3 Indian markets, Micromax partnered with telecom operator Airtel to offer a six-month double-data promotion on all 4G handsets in the lineup. Comparing the Canvas Trio Model Display Processor Camera Battery Canvas Blaze 4G 4.5-inch FWVGA 1.1 GHz quad-core Snapdragon 210 5 MP rear / 2 MP front 2,000 mAh Canvas Fire 4G 4.5-inch FWVGA 1.0 GHz quad-core MediaTek MT6735M 8 MP rear / 2 MP front 1,850 mAh Canvas Play 4G 5.5-inch HD IPS 1.2 GHz quad-core Snapdragon 13 MP rear / 5 MP front 2,820 mAh The Indian 4G Transition All three models ran Android 5.1 Lollipop and featured dual-SIM connectivity. At the time of launch, Indian carriers were investing heavily in LTE infrastructure, and domestic manufacturers like Micromax sought to capture first-time 4G smartphone buyers before...

In September 2015, BlackBerry CEO John Chen officially confirmed what tech analysts had speculated about for months: BlackBerry was preparing to launch its first Android-powered flagship smartphone, named the BlackBerry Priv. The name reflected the brand's dual heritage of privacy and privilege. A Unique Physical Slider in an Android World Announced alongside BlackBerry's Q2 fiscal 2016 financial results, the Priv combined a physical slide-out QWERTY keyboard with a 5.4-inch curved dual-edge touchscreen. The device ran standard Android with full Google Play Store support, supplemented by BlackBerry's proprietary DTEK security suite and enterprise productivity tools. A Historic Platform Pivot For over a decade, BlackBerry had relied exclusively on its proprietary operating systems. Transitioning to Android was a pragmatic acknowledgment that the app ecosystem deficit on BlackBerry 10 had become insurmountable. The Priv marked a pivotal turning point as the company shifte...

Shortly after the public rollout of iOS 9 in September 2015, independent security researcher Jose Rodriguez uncovered a significant lock screen bypass flaw that allowed physical access to a user's contacts and photo library without entering the device passcode. How the Vulnerability Operated The exploit relied on a flaw in how the lock screen interacted with Siri and the Clock app. By entering incorrect passcodes and invoking Siri at a specific timing interval, an attacker could trigger accessibility and search features that revealed the device's Address Book. From the contacts interface, an unauthorised user could browse photos, email addresses, and phone numbers without authenticating. Mitigation and Patching Security analysts advised users to temporarily disable lock-screen Siri access in device settings while Apple developed a software update. The incident underscored an ongoing challenge in mobile security design: balancing lock-screen voice convenience with strict dat...

In late September 2015, Facebook rolled out native 360-degree video support across its web platform and Android app, giving users an interactive way to explore scenes directly from their News Feeds. By dragging an on-screen cursor on desktop or rotating a handset in physical space, viewers could look around in every direction inside a recorded environment. Launch Partners and Technology To capture footage for the format, creators used specialised multi-camera rigs stitched into panoramic spherical video. Facebook partnered with high-profile creators and brands at launch, including GoPro, Discovery Channel, Saturday Night Live, and Lucasfilm, which debuted an exclusive 360-degree experience set in the Star Wars: The Force Awakens universe. A Step Toward Virtual Reality Maher Saba, Facebook's video engineering director at the time, framed 360-degree video as an important step toward richer, more immersive digital storytelling. The feature paved the way for Facebook's broader ...

In September 2015, Asus launched the Zenfone Go in India, entering the cutthroat sub-Rs 8,000 smartphone segment. Priced at Rs 7,999 across Flipkart, Asus exclusive outlets, and offline retail channels, the device aimed to bring Asus's sleek industrial design to first-time smartphone buyers. Hardware Specifications Display 5.0-inch HD (1280x720) IPS LCD Processor MediaTek MT6580 quad-core (1.3 GHz) Memory & Storage 2 GB RAM / 8 GB internal (microSD up to 64 GB) Cameras 8 MP rear with LED flash, 2 MP front Battery 2,070 mAh Operating System Android 5.1 Lollipop with ZenUI Connectivity Dual SIM, 3G / 2G, Wi-Fi 802.11 b/g/n, Bluetooth 4.0 The Market Dilemma The Zenfone Go competed directly against popular budget rivals such as the Xiaomi Redmi 2 Prime, Lenovo A6000 Plus, YU Yuphoria, and the second-generation Moto E. Although Asus bundled 100 GB of free Google Drive cloud storage for two years to sweeten the deal, the Zenfone Go had one critical disadvantage: it lacked...

In September 2015, NASA partnered with Virgin America and Alaska Airlines to conduct operational testing of a cockpit software suite known as the Traffic Aware Planner (TAP). Developed at NASA's Langley Research Center under the Traffic Aware Strategic Aircrew Requests (TASAR) initiative, TAP aimed to reduce commercial flight durations, fuel consumption, and carbon emissions. Real-Time Dynamic Routing Rather than relying solely on static flight plans drafted before takeoff, TAP connected directly to the aircraft's avionics hub on a standard pilot tablet. By continuously monitoring the plane's active position, altitude, remaining fuel, and flight route alongside real-time weather and restricted airspace data, the application calculated optimal altitude and route modifications mid-flight. Preventing Air Traffic Conflicts Crucially, TAP integrated automatic scanning of nearby aircraft transponders to ensure proposed flight path adjustments would not create airspace conflic...
