WikireaderA universal encyclopedia in your pocket. When was the first time I heard of that? Yes, I'm pretty sure the first time I read of this concept was in the Hitchhiker's Guide To The Galaxy. I won't be the first and last person to make the connection.

I've been fascinated with the concept of having universal knowledge in your pocket for a long time now. Data plans with mobile carriers, always carrying a USB thumb drive with lots of data that I'm particularly interested in at that moment, audio books, you name it. I've tried all possible ways to keep myself informed on various topics, on the go. I still haven't found the ultimate device, or approach, to meet all my needs. A nifty little gadget called WikiReader is taking a giant leap in the right direction to change all that. For 99$ you can have all the knowledge for servers and uptime in your pocket! I kid you, you can actually have a lot more than that. To be precise, about another 3 million other topics.

iPhone Web Server

The iPhone - one of the most, if not the most, popular mobile phone on the market. Innovative, when first launched, craved by people from all around the world, and widely accepted by the software development society. There are many great applications for it, most of them designed for plain fun and rich multimedia experience on the go. After a period of euphoria people start tinkering with the device even more, thinking - "What else can I squeeze from this device?".

Most of the times the answer is - a lot! We've all seen various wacky applications and some of practical use. One that you might not find practical at all is the web server for iPhone, called ServersMan. I honestly don't think this app will have a solid commercial value and extensive future implementations, but it is one of those things people will put on their phones only to tell friends they did so. Geeky, really geeky, and good for home use too. You can get all your data off your phone without syncing.


Time to Live (TTL)

Time To Live!We might have mentioned TTL in some of the previous posts related to Ping and Traceroute. TTL, or Time To Live is the transmission limit of a given data unit in a TCP/IP or UDP based computer network.

A data packet with a TTL value of 64 will cease to exist if it hasn't reach its end target in 64 iterations. The purpose of the TTL field is to avoid a situation in which an undeliverable datagram keeps circulating on an Internet system, a system that will eventually become swamped by such immortal datagrams.


DHCP (Dynamic Host Configuration Protocol)

Posted on June 24th, 2010 by Victoria Pal in Tech

DHCPDHCP stands for Dynamic Host Configuration Protocol. This protocol is used by DHCP clients to automatically obtain IP addresses. Most ISPs use it to make your life easy and be ready to browse the Internet right after you properly connect your network device.

Four steps, invisible to the user, take place before a host can obtain its IP address.
