A 10-Point Plan for Systems (Without Being Overwhelmed)

Types of Spam Filters

Spam filters are created to stop unwanted messages from being sent by unethical users. At present, there are so many types of spam filters being used. But because they are designed in various ways, how they detect spam varies as well.

Content-based filters are spam filters which are most popularly used today. As implied by the term, these filters work by spotting suspicious words or symbols contained in the subject line, header and content of an email. The process mainly relies on phrases or words that users themselves brand as spam, thanks to a feature email systems provide. This means that if a spam message includes words or phrases which are not on the user’s list, it will not be blocked until the same user adds them to the list. The benefit of this filter though is it can be customized to the user’s preferences.

Another type of spam filter used today is called the Bayesian Filter. This is different from the content-based filter in that it needs to be “trained” so it can determine whether an email is legitimate or spam. This “training” entails splitting the messages into tokens and saving them in their appropriate place – in a database for spam tokens or in the other database for legit tokens. This kind of filter requires minimal maintenance and can easily extract cues from the user’s usual messages. For instance, in a lawyer’s email, any message relating to the legal profession will be considered good. The main disadvantage of the Bayesian filter is its dependence on messages it has been trained with.

Another popularly used spam filtering system nowadays is called the Blacklist-Whitelist filter, where all good email addresses are added to the whitelist, while all the suspicious ones go to the blacklist. Using this filter, messages coming from whitelisted users are forwarded to the inbox, while those from blacklisted users are immediately blocked. A zero false negative may be expected by users with this filter. Its main drawback is that even if only a part of an IP was used to forward a spam message, the entire IP will be considered a spam sender when a real-time blacklist (RBL) is used.

The Challenge-Response Filter is another type of spam filter, which requires unknown senders to complete a certain action before the email could be received. The filter, for instance, may request the sender to give his website address so the email’s legitimacy can be confirmed. This filter is perfect for email users with low traffic.

Lastly, the Community Filter is equipped with a central servers to which users can forward suspicious emails. The server’s job is to save the “fingerprint” of those emails. If the email has been flagged several times before by other users, it will be blocked, although many users would have already opened it.

Make Your Home More Comfortable by Choosing the Most Efficient Air Conditioning System

Selecting an air conditioning system for your home is a decision you’ve got to be very careful with. HVC is not really cheap. There’s no reason at all to ruin the family’s budget. There is really a need for you to look at the cost of air-conditioning units. While cost is crucial in a HVAC, efficiency, air quality and installation are equally important. Specifically, the most important features you need to consider in a HVAC unit besides price include power capacity that fits room requirements, energy consumption, durability, ease of installation and repairs and maintenance.

The unit you’d like to purchase will be dependent on the size of the rooms in your house. A small HVAC system may not provide enough power to satisfy cooling and heating requirements of large spaces. A big unit, the other hand, cycles off and on quickly and this can leaves rooms either unreasonably hot or cold.

A cost effective system is the best buy. You can determine whether it’s cost effective or not by looking at its Seasonal Energy Efficiency Ratio (SEER). Those with higher SEER are more cost effective. Choose a money saving HVAC that also comes with warranties. Compare quality and prices and get the unit that saves money without surrendering quality.

Select an unobtrusive system

There are HVAC systems that are irritatingly noisy. Get a unit that won’t disturb your sleep, so be more thorough when you explore the market.
Make sure the unit comes with detailed installation and operation manuals. An air conditioning unit delivered without an instructional manual and not properly installed is useless. Minor problems in the operation of the system can be taken care of quickly if instructional manuals are provided. Instruction manuals should contain not only instructions on maintenance procedures but also instructions on programming the thermostat.

Make sure to buy an air-conditioning system that improves indoor air quality. Give your undivided attention to the system’s features that are supposed to maintain the quality air in your home. You’d want to know about the Bi-Polar Ionization Units, air filters, and UV Lights your system uses.
