Security Engineering


Security engineering is concerned with the development and evolution of systems that can resist malicious attacks, which are intended to damage the system or its data or information.
Software security engineering is part of the more general field of computer security.

Software engineers should be aware of the security threats faced by systems and ways in which these threats can be neutralized.

Lightspeed and Powerplay


Lightspeed, its low-latency wireless-transmission technology, and PowerPlay, a way to charge mice while using them on a custom mat. Both solve the main complaints some gamers have around wireless mice: that they’re laggy and could lose charge at any moment.

PowerPlay is the more intriguing of the two because it’s something we’ve never seen before in the mouse arena. High-end wireless mice might give you a charging cradle, while others usually pack a cable in the box to juice back up.

Pervasive Technology and Mobile Computing


The realisation that pervasive technology can provide a direct link between data and people has crystallised into the idea of participatory sensing, which appropriates everyday mobile devices such as cellular phones to form interactive sensor networks that enable public and professional users to gather, analyse and share local knowledge.

Its potential for data collection at a high granularity in space and time, very difficult for scientists to achieve otherwise, together with its potential for citizen involvement at all layers of society, make this an extremely promising tool for monitoring and managing the environment.


Sound Pollution in Bangladesh


I think there have no proper law against this terrible sound pollution in Bangladesh. My hearing system should be damage for this heavy sound of ambulance and Police team’s vehicle.

Though sound pollution happening in many countries, But In Bangladesh, sound pollution is another one greatest issue for the environment.
Most probably, Ambulance, VIP & Police Protocol team vehicle always create so enormous sound on the road that they can go forward swiftly.
Absolutely, this is their duty. But, when an ambulance and Police vehicle fall into a traffic jam. They must try to do wait and stop their whistle of vehicle; otherwise they misconduct the sound pollution law.


Zigbee | IEEE 802.1.5 | IEEE Standard 802.15.2012


A second personal area network standardized by the IEEE is the 802.14.5 standard [IEEE 802.15 2012] known as Zigbee. While Bluetooth networks provide a “cable replacement” data rate of over a Megabit per second, Zigbee is targeted at lower powered, lower-data-rate, lower-duty-cycle applications than Bluetooth. bluetooth_street_small

For example, home temperature and light sensors, security devices, and wall mounted switches are all very simple, low-power, low-duty-cycle, low-cost devices.
Zigbee is thus well-suited for these devices. Zigbee defines channel rates of 20, 40, 100, and 250 Kbps, depending on the channel frequency.
