My friend recently lost her domain name as she forgot to renew it. Now there is no way she can get back the domain name. So how do you find out domain expiration date?
There are 3 simple ways:
By checking the public WHOIS database
Visit whois service here and enter your domain name. You can also use your domain registrar whois service to find out information.
By logging into your domain service providers account
Login to your domain registrar account and list expiring domain. Make sure you set all domains to auto renewal. Finally, make sure your credit card / payment information is upto date to avoid delays.
By using automated shell scripts for Linux /UNIX / Mac OS X
You can grab modified shell script that run as a cron job from your own Mac OS X / Unix computer. This script checks to see if a domain has expired. It can be run in interactive and batch mode, and provides facilities to alarm (email) if a domain is about to expire in advance.
Free Windows Software
If anyone has any information about free domain remainder utility for Windows XP / Vista, please add them in the comments.
Most domain register provides a series of reminder emails to you as the domain name approaches its expiry date. Make sure you whitelist those email address. If domain names are quite important register them for 5-10 years and lock all domain names.
Robert Graham, the CEO of errata security, surprised attendees by hijacking a Gmail session on camera and reading the victim’s email. He went even further by demonstrating the attack to us in person, taking over another journalist’s Gmail account and then sending us sheep-loving emails.
Now you know why it’s dangerous to check your web emails in public hotspot or through open wi-fi connections. You can try https session and only use secure wifi connection to avoid problems.
From the article:
The attack is actually quite simple. First Graham needs to be able to sniff data packets and in our case the open Wi-Fi network at the convention fulfilled that requirement. He then ran Ferret to copy all the cookies flying through the air. Finally, Graham cloned those cookies into his browser – in easy point-and-click fashion - with a home-grown tool called Hamster.
POP3 has made earlier versions of the protocol obsolete. Generally you will not find a free POP3 server. Usually your ISP or webhosting company provides IMAP or POP3 access.
But where can get a free POP server?
You can use Google’s GMAIL service which provides a free POP3 service. You can download email using POP3 and send email using Googles SMTP server. According to Google:
POP, or Post Office Protocol, lets you download messages from Gmail's servers onto your computer so you can access your mail with a program like Microsoft Outlook Express or Netscape Mail, even when you aren't connected to the Internet.
POP access is free for all Gmail users and we have no plans to charge for it in the future.
The Dynamic Host Configuration Protocol (DHCP) is a set of rules used by communications devices such as a computer, router or network adapter to allow the device to request and obtain an IP address from a server which has a list of addresses available for assignment. The Dynamic Host Configuration Protocol (DHCP) is a member of the TCP/IP suite and a protocol that is designed to save network administrators a lot of time and effort. A successful DHCP implementation can do just that.
This article explains setting up DHCP on tens, hundreds, and even thousands of computers can be daunting. Here's how to do it easily with Windows Server 2003:
As you probably already know, every computer that communicates on a network does so via an IP (layer 4) address. The goal of DHCP is to provide a mechanism of automated address delivery, to give every computer its own IP address without an administrator having to type them all in manually. In small networks, this isn't too big of an issue. However, in networks with tens, hundreds, and even thousands of computers, the task of IP address management is daunting. Luckily, Windows Server 2003 provides a means for us to implement DHCP with its own DHCP server service
PDF (Portable Document Format ) format is already optimized and he de facto standard for document publishing on the internet and other media.
A PDF file is often a combination of vector graphics, text, and raster graphics. The basic types of content in a PDF are:
* text stored as such * vector graphics for illustrations and designs that consist of shapes and lines * raster graphics for photographs and other types of image
Because all graphics and other stuff PDF file is optimized. You can use program such as Winzip or 7-Zip (or command line utility winzip/zip) to package and compress a pdf file. My personal experience shows that you will not gain much benefit from compressing a PDF file as compression ratio is very small.
I'd be interested to hear if you have other software program to consider when compressing a PDF (remember it must provide a good compression).
The name "Ogg" refers to the file format which can multiplex a number of separate independent free and open source codecs for audio, video and text (such as subtitles). Files ending in the .ogg extension may be of any Ogg media filetype. The term "ogg" is often used to refer to audio file format Ogg Vorbis, that is, Vorbis-encoded audio in the Ogg container.
You can use VLC player to play ogg files under Windows XP or Vista.
A nice list that will help you to clean up and speed up MAC OS X :)
From the article:
After Apple recently announced a delay to OS X 10.5 Leopard I had to delay my iMac upgrade until the Autumn. This led me to thinking about how to speed up Tiger to get the most out of my ageing G5.
This is what I came up with: 1. Repair Disk Permissions Navigate to Applications > Utilities > Disk Utility. Select your Macintosh HD and select Verify Disk Permissions. If needed you can then Repair Disk Permissions.
2. Clear out login items Its good to check that unwanted programs are not starting up when you login to your Mac. This can be done from System Preferences > Accounts > Login Items.
