The GUI is very simple and you don’t have a lot of options to play with, in fact all you can do is customize the toolbar on the top. The color of the lines can also be customized. Drop one or two images to the panes and start indicating the similar areas of the pictures by dragging lines. You can add points by clicking on the picture and remove them with backspace....

Understanding RFCs To fully understand what an RFC is, one must also understand what gave birth to them, and why they were necessary at the time in which they were first created. A long, long time ago, the Internet was run on a small network of computers known as ARPANET. It was a project of the United States Department of Defense. When the Internet was born, there was a need for protocols with which to communicate so that the way in which computers talk could be completely standardized....

I had no issues installing it on several devices, but for the purposes of this walk-through I am using a Kindle Fire HDX, mainly because it happens to have a nice case/stand in the form of the Origami, which makes it convenient for media. Once installed, you will be prompted to log into your MyPlex account upon first startup. This is not something that is necessary for you to have, but it’s free....

While you can change privacy settings and limit who can find your children on some social sites, you never really know what they are doing or who they are talking to and about what. Recently a co-worker told me about a way she helps shelter her kids while still letting them use Facebook. She uses a site called Togetherville. Getting started You will need a Facebook account of your own to start....

High email deliverability and positive sender reputation were major criteria which eliminated fancy, cheap email hosts.

1. AirPush Detector One of the most common kinds of ads in the notification bar is an AirPush advertisement. The AirPush Detector will scan all of the applications on your Android and find any known apps to use the AirPush ad system. When you have the list, you can start to delete the apps.

Note: as usual, you should consider the somewhat hazy legalities surrounding game emulation before proceeding. The following guide doesn’t offer advice on getting your hands on ROMs and ISOs. Getting Started The first thing you need to do, of course, is install Retroarch from the Play Store. Once you’ve done that, open Retroarch, and you’ll be presented with the main menu, which may mean absolutely nothing to you if you’re unfamiliar with Retroarch....

Test Your Internet Connection To begin with, ensure that the problem is with Safari and not with your internet connection. For this, open, say, a non-Apple app like Facebook or Chrome, and see whether the website or the feed loads. If it does, then Safari is at fault. Otherwise, your internet connection is at fault. If it’s the former, move on to the next step. Turn on Mobile Data for the Safari App If you’ve been exploring your iPhone’s data-saving features, which let you specify which apps have access to your phone’s mobile data, then there’s a chance that you turned off mobile data for the Safari app....

This isn’t a difficult process, but it can be a little time consuming if you’re doing this often enough. Wouldn’t it be easier if you could initiate a Google search for any image, right on its respective Web page? That’s where the Search by Image Chrome extension really comes in handy. Let’s see how this extension makes the Google search by image function even easier. Getting Started Install the Search by Image extension from the Chrome Web Store....

If you’re like me, your browsing experience is spread across multiple devices running different operating systems. I spend a lot of time on my Mac, way more than I do on my iPad or iPhone. And I also carry an Android phone (for work). When I’m on Twitter or catching up on RSS, and I come across an iOS app that I just need to try out, right now while it’s hot, if I don’t save it somewhere, I’ll just forget about it, and my Twitter followers will never get to hear my snarky comments about the hot new app....

Self-signed Certificate vs. Commercial Certificate Self-signed Certificate is signed by its owner. It is generally used for testing local servers and development environment. Although self-signed certificates provide the same level of security between website and browser, most web browsers will always display a security alert message that the website certificate is self-signed and cannot be trusted, as it is not signed by the Certificate authority. Commercial Certificate is an authorized certificate issued by a trusted certificate authority....

SlideScreen is a visually pleasing home replacement utility for Android. There are two ways to utilize SlideScreen. You can use it as a full replacement for your home screen or as a standalone app. Whichever you choose, you will get the same interface and functionality. The concept of SlideScreen is somewhat different from the traditional Android home screen. Instead of providing you several screens to place your widgets or shortcuts, there is only one screen in SlideScreen and all your information from various media streams (SMS/emails/RSS feeds/calendar event/Facebook/Twitter/Stocks) are loaded on the screen....

Go to the Compatibility tab and check the box “Run this program in compatible mode”. In the dropdown field, select “Windows Vista (Service Pack 2)”. Click Ok. If you have your Windows Live Messenger open, close it and reopen it. It should now appear in the status bar when you minimize it. Note: The above method will work for Windows Live Mail as well.

Fortunately, macOS lets you configure the shortcut menu easily and extend it with third-party utilities, a few of which are covered below.

With Facebook investing billions on WhatsApp, there is no doubt that WhatsApp’s success was assured. Nonetheless, if we compare WhatsApp to Telegram from a technical standpoint, the former comes up short. Find out what you’ve missed by not giving the lesser-known messenger apps a chance they deserve. Telegram Has a Better Desktop App While Telegram has not been around as long as WhatsApp, it’s still considered a great desktop app....

I’ve seen displays set up for delivery drivers during other parts of the year: treats and bottled water set out on the front porch, inviting drivers to treat themselves. It’s a great gesture and probably also ensures that your packages will be treated kindly. How “Alexa, Thank My Driver” Works Image credit: Unsplash

1. Skype When it comes to communication, it’s hard to beat Skype (although it does have competitors nipping at their heels, such as Google Hangouts). If you work online for a living, then you will probably be using Skype all the time to communicate with colleagues and / or customers. The Mac version of Skype does have a slightly different design than the Windows one, and it is pretty clunky in my opinion....
