The overall feeling of a website is much more than just a logo design. While graphics and logos are necessary, the entire website should feel like one big entity. This occurs through matching typography and icons, but also through the choice of colors. All websites start out as a blank canvas capable of possessing many decorating and styling elements. It’s worth examining what other sites have done and how their color scheme matches with the logo and overall site content. Even if you’ve settled on a particular shade of burgundy, you might look into darker shades of red and maroon for other areas. Providing the right balance of colors on your website can lure more viewers and can make the overall content on your website more appealing.... Read more

Home Mail Server?
Categories: Tech | Pubby Cash Received: 0
It sounds like a great idea to set up a mail server at home. It is not difficult to do so. All you need is to install an HMailServer and run it on your home computer 24 hours per day. You will get featured emails like [email protected]. Isn't that cool? However, you might end up being able to receive emails only while lacking the ability of sending emails to the outside world. You might think is port 25 (the port of sending emails) open? Yes, it is absolutely open, not blocked by firewall and home router for sure. You have gone through all the settings on your side, and still cannot solve the problem. The reason is: your ISP blocked port 25 for the reason of avoiding email spamming. How to check if your ISP has this port blocked? Here is my method: use "cmd" to open the command window, and then type "telnet mail.hmailserver.com 25". If you get connection errors, that means your email sending (via port 25) ability has been restricted. You probably need to enable telnet first by opening this feature in windows. There are a bunch of articles on the internet guiding you how to do this. To check if your server's specific ports are open, in addition to the above telnet method, you can also go to canyouseeme.org, and enter a port to check. It will return an error if it is not open. And then you can do some troubleshooting accordingly. The final question is: How to solve the problem? How to bypass your ISP's port 25 restriction? You could use an smtp relay service through a third party which allows you to connect to their smtp server at a port other than your blocked port 25, and they will send out the email for you. The downside is the free version of this service usually put a limits on the daily or monthly emails you can send out. However, if you are running a home server as the title says, not for large scale business use, a 100 emails per day limit does not sound too bad. ... Read more
Kaprekar's Constant
Categories: Tech | Pubby Cash Received: 0
6174 is known as Kaprekar's constant after the Indian mathematician D. R. Kaprekar. This number is notable for the following rule: (1) Take any four-digit number, using at least two different digits. (Leading zeros are allowed.) (2) Arrange the 4 digits from highest to least to form the greatest number possible with those 4 digits. Then do the opposite and arrange those digits from least to highest to form the smallest number. Subtract the smaller number from the bigger number. Go back to step 2 and repeat. The above process, known as Kaprekar's routine, will always reach its fixed point, 6174, in at most 7 iterations. Once 6174 is reached, the process will continue yielding 6174. The only four-digit numbers for which Kaprekar's routine does not reach 6174 are repdigits such as 1111, which give the result 0000 after a single iteration. All other four-digit numbers eventually reach 6174 if leading zeros are used to keep the number of digits at 4.... Read more
