The Best Free Software 2013
For five years, PCMag has brought you an ever-bigger, ever-better list of desktop software that will cost you absolutely nothing. But this year, we're shaking things up a bit. Instead of an annual look at the best free software, we're going monthly.
Since software can cost thousands, you might wonder why and how you can score immensely useful programs for free. This happens for the very good business reason that developers often try to gain traction with the public by giving away their product, or at least a "lite" version of it, in the hope that you'll upgrade to a paid version. It's called the freemium model. Sometimes all they want is a donation. In other cases the programs display ads to keep the money flowing. In the end, by giving it away the developers gain recognition at the very least, if not money straight away. More importantly, it serves you, the user, because you've got access to tools for your computer that rival anything you'd pay for.
We're throwing in all the worthy apps that run on Windows 7 and 8, the latest MacOS, and of course, the cloud-based Web apps that run in a browser like Chrome, Firefox, or IE to use anywhere. We'll let you know which OS each title runs on, and if it has a mobile version you should nab for your smartphone.
Look for a new category of free software titles every month. Be sure to let us know what freebies you'd like to see next, and as always, tell us in the comments section if we missed your favorite.

Buying a used computer CPU
A CPU is one of the most important parts of your computer system.
It’s like the brain of a computer system and is responsible for most of
the data processing. As a result it plays a major part i
n a computer
system’s performance.
Buying a used CPU can lead to significant savings at minimal risk.
New CPUs are released all the time so older models can be had at a good
discount. A second-hand CPU is the most risk free purchase of
used computer hardware you can make. This is because a CPU either works
perfectly or not at all so it’s easy to tell what condition it is in. If
it works at all then it’ll continue to work happily for decades. If it
doesn’t work then it’s dead and worthless. There is no room for doubt.
However, there are certain steps you can take to ensure that you
purchase a fully functioning CPU:
- First take the CPU out of its socket and examine it closely. Look at the top of the CPU where heatsink is. It should be free of any burn marks or other obvious signs of damage. The top of the CPU will likely have thermal paste on it so removing that thermal paste maybe required. You can use rubbing alcohol to do that. Obviously don’t use water.
- Take a good look at the underside of the CPU. If it’s a pinless chip make sure that all the contacts are in good condition. There should not be any foreign matter covering them. Foreign matter covering the contacts can cause short circuits and even cause the CPU to burn. If the CPU has pins then make sure that all the pins are present and fully upright. Bent pins can cause short circuits. Broken pins can cause a CPU to malfunction.
- See the CPU in action. The seller must have a motherboard, RAM, PSU etc. so that you can install the CPU and see it functioning in a working system. When booting up the system be sure to go into the BIOS menu to verify that the CPU is the correct model. Also make sure the system boots the operating system successfully.
- If possible run a CPU stress test like prime95 for a few minutes. Using a CPU temperature monitoring software like real temp you can see whether the CPU runs within the manufacturer’s prescribed temperature limits when under load. If it doesn’t you may have to reapply the thermal paste and reseat the heatsink fan.
The rule of thumb is that you have to reapply thermal paste every
time you remove the Heatsink Fan or HSF assembly from top of the CPU. So
once you’ve bought a used CPU you will need to reapply thermal paste.
You can buy cheap thermal paste in large computer shops locally. Small
shopkeepers will not know anything about thermal paste so avoid
asking them. Before applying the new paste you will have to remove the
old paste from the bottom of the HSF and the top of the CPU using
alcohol swabs purchased from a pharmacy. Then you install the CPU in its
socket on the motherboard, apply a tiny amount of the new paste onto
the top of the CPU and install the HSF.
Buying a used CPU can save you quite a bit of money and following the steps above ensures that you get a working chip.

Facebook is the many-headed frenemy, the great underminer. We know this because science tells us so. The Human-Computer Institute at Carnegie Mellon has found that “passive consumption” of friends’ feeds and your own “broadcasts to wider audiences” on Facebook correlate with feelings of loneliness and even depression.
