This week started with news titled D-Link Router backdoor vulnerability discovered and Back door found in D-Link routers. This rather worrying security vulnerability on several D-Link branded modem routers made me to check my system because I use D-Link firewall. But let’s start from the basics. Because D-Link device was on news, where is a →
I just read an interesting article True or false? High-power LEDs don’t generate IR heat in the forward direction like a filament lamp that give something to think about on LED technology. I and you have for sure read that a high power LED emits no UV or IR and that any heat is created →
