WiFi Basics Part 2: Standards and Amendments Through 802.11n

Today, WiFi is everywhere: coffee shops, restaurants, retail, hotels, sports venues, etc. We can access it from our laptops, tablets, and smartphones. At home there may be game consoles, smart home devices, and set top boxes. I have several ChromeCast devices. They turn your TV into a wireless network device that you can stream movies from your computer or phone directly to the TV. It is so pervasive in our lifestyle that we don’t give it a second thought.

Find out more about crashes in Mozilla Firefox

It is often not clear what caused a web browser to crash. While you sometimes get a good clue by analyzing what you did last, opened a link that supposedly crashes Firefox when doing so, it is often not clear why Firefox crashed at that point in time.

While you may be interested to know why the browser crashed to avoid this in the future, you often have to correct issues caused by the crash.

AfterShip is probably the best Package Tracker for Android

I recently sold a couple of old game consoles and games on eBay, something which I have not done for years. Since I had to ship all items as packages, I started to look for an application to help me keep track of them all so that I would stay in the loop and know when packages were delivered to the buyers.

Microsoft aims to change authentication with Microsoft Passport

If you want to sign in on a web service currently you have to provide username and password to do so. This is neither convenient nor overly secure, considering that the server you communicate with has to store username and a hashed password for that.

Microsoft envisions Passport to change that by allowing users to sign in to applications and web services without passwords.

Windows 10 to ship this Summer

Who would have thought that? Microsoft announced a few moments ago that it will ship the company's latest operating system Windows 10 this summer to 190 countries.

What this means is that Windows 10 will ship no later than August / beginning of September which is earlier than the expected October release date the company picked for Windows 7 and Windows 8.

The release date would ensure that the final version of the operating system is available before the end of the important back to school period.

What’s the best free file synchronization software for Windows?

File synchronization software comes in many shapes and forms. From cloud storage services that allow you to sync files with the cloud and from there to your other devices to local solutions that you use without third-party involvement.

This article concentrates on local solutions only that are offered for free and run on all supported versions of the Windows operating system.

While cloud syncing services have their advantages, it makes little sense to use them when you want to sync files in a local network between devices.

Find out which RAM your computer supports

Depending on how much RAM is installed in your computer, it may benefit greatly from increasing it. This is especially true if less than 4 Gigabyte of RAM is installed in the machine but may make sense in other cases as well depending on the operating system and applications that you run on it.

If you are new to all of this, you may run into troubles easily. Questions about which types of RAM your computer supports are not easily answered if you don't know where to look for those answers.

No more recovery partitions in Windows 10 and other storage gains

When I check the storage space that Windows uses on the two computer systems I run it on, I notice that it occupies 43.4 Gigabyte on a Windows 7 64-bit Pro system and 15 Gigabyte on a secondary system using Windows 10. That's only the Windows folders though and does not include recovery partitions, data in the user or programs folder.

You can use a freeware like TreeSize Free to display the size of the Windows folder on your system.

That i icon on YouTube? That’s the new Cards feature

If you have watched a YouTube video lately you may have noticed an i icon appear in the top right corner on the site like on this video here.

This is YouTube's new Cards feature that the company sees as an evolution of annotations.

A click on the icon opens a card which displays additional information related to the video and added by the maker of the video.
