For some, video conferencing is just a click away but what about those who aren’t really that fond of using Skype or Google Hangouts? Is it even possible for you to convince them to install a video call and chat application just so you could talk or chat to them via webcam? Well, some of them might say yes but wouldn’t it be much better if you can make a video call without even installing any software or application? Speaking of which, you might want to check out this cool web-based video conferencing service called appear.in.
WHAT IS IT AND WHAT DOES IT DO
Compared to other video call and chat applications, appear.in is a web-based group video calling service. What’s great about it is that you’re not required to login or register. There’s also no need for you to download and install any particular app or software. With appear.in, all you need is a stable internet connection, someone to talk to and of course – a supported web browser. As of now, you can use appear.in on Chrome, Firefox and Opera. So if you want to chat or start a video call, just create a chat room and then share the link to your chat room to your recipients. It’s as easy as that.
- Easy to use, web-based
- No user registration or login required – there’s also no need for you to install any software or app on your computer
- Neat, stable and responsive user interface
- Can cater up to eight participants
- Supports screen sharing
- Uses SSL/SRTP to secure and encrypt your chats and video conversations
- You can claim a chat room as your own
- You can lock a room to prevent others from joining in without your permission
- You can view or set your chat room in full screen
- You cannot drag, resize or move the chat box
- No emoticons for chats
- Works using WebRTC, so it will only work with browsers that support WebRTC
The way how appear.in works is quite simple. Since it’s purely web-based, you don’t need to install anything on your computer. If you want to start a video conversation, all you need to do is to access its homepage and then you create a chat room (or simply called as “room”) by typing in your preferred chat room name in the provided text box. You can create any name that you want but you can also opt to generate a random chat room name like “gamy-salmon”, “thirsty-grouse”, etc. Once you’re done, just click the “Create” button and make sure that you allow the web app to access your webcam and microphone. Just keep in mind that the recommended number of participants in a chat room is only limited to eight. If you go over this limit, there’s a possibility for the web app to crash or you might experience some unexpected errors.
You should also keep in mind that every appear.in chat room has a unique link. In order to invite other people to join your room, what you need to do is to send or share your room’s link to your recipients. So as soon as they click the link, they will automatically appear on your screen and vice versa. Other than this, you can also opt to keep your room locked so that no one else can join your video conversations.
If you want to gain more control over your chat room, you can own it by clicking the “Claim” button. As a chat room owner, you are given the privilege to secure your room with a password. You can also customize your room by setting your own background image or photo.
Functionality wise, appear.in is very easy to use. It’s hassle-free. The video and audio quality is also good plus it doesn’t crash or lag. It has screen sharing and full screen functions. Its user interface looks neat and you can also use its chat box to send a message to your recipients. It may lack some tools and options that would make it more user-friendly but what’s more important is that it does what it’s intended to do and so far, it’s doing a good job. It also uses SSL/SRTP encryption to secure your video calls and chats.
Most computer users have dozens of passwords: Banking websites, social media, bill payments, online retailers—all of them require secure logins. Because so many websites vary their password requirements it’s hard to use just one password that’s easy to remember, not to mention what a bad idea that is.
Keeping your online identity secure requires the use of complicated and varied passwords, and managing all of them can be nearly impossible. 1Password is a multiplatform app designed to solve your problems.
- What is 1Password? 1Password is a password management app that stores all your login information behind one master password. It is available for iOS, macOS, Android, and Windows.
- Why does 1Password matter? Password hacking continues to grow in sophistication, making complex, hard-to-crack passwords essential. 1Password can auto generate random passwords, greatly increasing account security.
- Who does 1Password affect? 1Password affects anyone who uses the internet. Secure passwords are essential in the internet age, and 1Password makes managing them incredibly simple.
- When is 1Password happening? 1Password has been on the market for 10 years and continues to grow in sophistication and ease of use.
- How do I make use of 1Password? Interested users can download 1Password at its website, in the App Store for iOS, and Google Play for Android.
What is 1Password?
1Password is an app used for managing the multitude of passwords each of us has nowadays. Put simply, it’s a secure vault where you can put passwords, credit card numbers, and other sensitive personal information.
1Password uses a single logon for access to all stored passwords, and users can also use their fingerprints to log in on applicable devices.
Users who want to share information among family members will find 1Password particularly useful: it has a family sharing system built right in. Administrators can share select information with certain family members, enabling parents and children to access shared accounts.
Apps are available for iOS, Android, Windows, and macOS. The desktop versions of the app can also automatically sign in to secured accounts if a user is logged in to 1Password.
Why does 1Password matter?
Information security has always been an arms race, and if anything it has only become more intense. It’s hackers vs. infosec professionals in a constant competition to one up each other: that’s why apps like 1Password are so important.
1Password can’t guarantee you’ll never be compromised but it’s a good start. The app itself uses AES-256 encryption, which is incredibly strong and nearly impossible to crack. It is made even more secure with the use of fingerprint scanning technology like TouchID: If you’re not the one with your phone 1Password isn’t getting unlocked.
To round matters out, 1Password will automatically generate complicated random passwords for you. Since it is automatically filling them out itself you won’t need to worry about forgetting them.
In short, 1Password matters because hackers are getting better and better at cracking weak passwords.
Who does 1Password affect?
How many passwords does the average internet user have? It’s hard to know how many are unique, but the average US email address has 130 accounts registered to it. Anyone with even a fraction of that many accounts is affected by 1Password.
It is very tempting to reuse passwords or vary new ones just slightly, and that’s a serious security risk. 1Password can do a lot to nullify that risk on both mobile devices and traditional computers.

Do you keep hearing about cloud hosting and wonder how it differs from a regular hosting plan? Perhaps you just built a new site and are wondering if you should give the cloud a try?
Cloud hosting is a more reliable, scalable, and secure option than a regular shared hosting plan. But shared hosting is, usually, cheaper and easier to set up.
In this article, Lucero Del Alba will cover everything from control panel options, migration issues, and the pros and cons of each option. We’ll get to see what each option is about and —hopefully! — help to you decide whether it’s better for you to stick with shared hosting, or if you should switch to a cloud plan.
Once Upon a Time on a Shared Hosting Plan …
Traditionally, when we needed to put a site online, we’d buy a domain, get a hosting plan, and FTP the site from our computer to the web. We grew so used to it that it became second nature.
We would typically have features such as a very comprehensive control panel, statistics, and email hosting for the domains registered on that account, among other things. But also some hard limitations, such as a certain amount of disk space, a given bandwidth, and a fraction of the CPU and the server memory.
For many brochure, portfolio, blog and small business sites, that’s perfectly adequate. But for many businesses, it’s not ideal. And even for a freelancer maintaining a couple of simple sites, it’s possible to run out of resources for a given site from time to time. (It’s no fun being asked by a client why the site is down.)
The VPS and Dedicated Server
One way of upgrading is to buy a bigger, slightly more expensive plan with a little more resources, in the form of a VPS (virtual private server). And if that doesn’t cut it, you can rent a dedicated server — that is, a full rack on a hosting company’s data center.
With a dedicated server, you get all of the server resources in a non-shared environment for, let’s say, $100 a month. Yes, about a 20x more expensive than a basic shared hosting plan — but hey, you wanted the whole thing, didn’t you?
Whether you’ve stuck with shared hosting or jumped into the world of the VPS or dedicated server, it has probably all worked just fine, and you may never have contemplated trying anything else. Believe it or not, though, there’s now a generation of web developers that barely know what FTP is, having never used it.
… and Then the Cloud Hosting Plan Came Up
When Amazon Web Services (AWS) was first introduced, everything was new and it seemed like you needed to take an intensive course before you were able to start operating with this cloud infrastructure.
But things have changed since then. Not only have more providers come onto the scene, but also more solutions that can be used out-of-the-box, including cloud hosting.

With technology always advancing and the automation all types of routine jobs, there’s never been a better time to learn to code and pick up some specialist skills. The demand for these skills has never been higher, and what’s more, you can master them from the comfort of your own home.
In this article, we’ll be discussing some free and premium resources to help you get started with learning for starters and more skilled coders also. Most of the following resources will cover wider areas, which adds even more to our value.
My favourite website to read articles on is: SitePoint
SitePoint shares articles very frequently, has various tutorials for both beginners and experts. The articles are all free to read, but SitePoint has premium content also called SitePoint Premium, with video tutorials and top-quality books to learn from.
Next is: Tuts+
As part of Envato’s creative ecosystem, Envato Tuts+ contributes to the mission of “helping people learn and earn online”.
Envato Tuts+ tutorials are available to you completely free—all 23,360 of them!. Based around specific projects, they include step-by-step written instructions and screenshots to help you practice and master the skills needed to create a practical outcome.
Standards for developing flexible, durable, and sustainable HTML and CSS. Really handy basics that should be followed, written based on years of experience.
High-level advice and guidelines for writing sane, manageable, scalable CSS. Harry Roberts is a CSS specialist, who does lots of presentations in conferences, worked with well known companies such as Adobe, Google. This guideline is a bit more advanced, but will truely be a turning factor in your CSS writing.
More advanced: Sass guideline by Hugo Girauduel
Sass is an extension of CSS that adds power and elegance to the basic language. Sass’ ultimate objective is to fix CSS’ flaws. CSS, as we all know, is not the best language in the world . While very simple to learn, it can quickly get quite messy, especially on large projects. This is where Sass comes in, as a meta-language, to improve CSS’ syntax in order to provide extra features and handy tools. Meanwhile, Sass wants to be conservative regarding the CSS language.
Starting with: Treehouse
Learn from over 1000 videos created by expert teachers on web design, coding, business, and much more. Their library is continually refreshed with the latest on web technology so you’ll never fall behind. They have free trial for two weaks, after that it costs 25 $ / month.
Two more I like: Codecourse & Codecademy
Codecademy provides a wider area of knowledge. They extend their video courses with useful resources for developers such as: version controlling with Git, command line tutorials, more advances topics like Sass & AngularJS. They have many free to watch tutorials, and some premium content for 20 $ / month. I would recommend their free tutorials for starters since it’s really well organised and makes the user follow up a real life example.
Codecourse gives more attention to framework specific tutorials, I would recommend their free courses for coders who have already mastered the basics.
Final personal favourite one: Laracasts
Learning to code positively affects all areas of your life and gives you a newfound sense of energy to really pursue the goals you want in life.
A lot of people think that this positive impact is limited to improving your technological skills and ability to use a computer, but it’s so much more than that. It changes your whole life, from lifestyle, through social life, to career. Wish all of you starters good luck!
The following article was written by Mike MacCana, founder at CertSimple. It explains that HTTPS can provide identity, SEO, access to HTML5 powerful features and even keep network carriers from messing with your site’s content. Read on for how or see the original article here: CertSimple
You know this, but let’s recap with a practical example:
Alice needs to send a message to Bob, privately. Someone – let’s call them Malory – sets up a wifi access point in Alice’s favorite cafe, Malory can happily reconstruct all the HTTP traffic between Alice and Bob. Malory runs
apt-get install driftnet
on her Linux laptop and enjoys a flat white while everyone else’s HTTP browsing appears on her screen in realtime.
Except HTTPS traffic won’t show up on Malory’s screen: things encrypted with a website’s public key can only be decrypted with the website’s private key. Because the website’s private key is (hopefully) only available to the website, Malory can’t decrypt the traffic.
1. Ownership attestation
Making sure Alice is actually talking to Bob. There are different levels of validation: domain validated certificates prove control of a domain, but don’t assert any particular entity controls the certificate – even if the domain is similar to a well known company.
The EV certificates you see at banks, online wallets and other high trust websites check the company applying for the certificate is who they say they are, so you know whose key you’re encrypting with. The browser displays the company name and where the company is registered, but you can check the full details inside the certificate:
2. Search engines use HTTPS as a ranking signal
You’ll need to set up HTTPS for your whole site rather than using something like a ‘billing’ subdomain. This also gives you flexibility to make previously static content interactive. Want to let users give you their contact details on a blog post? You’ve already set up HTTPS so you can do that securely.
3. Ability to use HTML5 ‘powerful features’
- Video and Microphone
- Device motion / orientation
- Pointer locking
- Encrypted Media Extensions (aka DRM)
This has already started in the current version of Canary, with geolocation being made HTTPS only since Chrome 50. If you run Canary – and soon for all Chrome users – you’ll need HTTPS for geolocation. Otherwise
navigator.geolocation.getCurrentPosition() will fail with:
4. Not having your content modified by carriers
Carriers are awful:
- Comcast adds advertisements
- AT&T adds tracking
- Verizon adds tracking and sells access to advertisers
- T-Mobile re-encodes videos, degrading quality
- The Chinese government makes your users attack GitHub.
The only thing that’s stopping them? HTTPS. If the carrier can’t decrypt the packets passing through their network (because they don’t have the site’s private key) they can’t inject their own content.
This is effective enough to the point where nefarious carriers have asked users to install configuration profiles to add the carrier’s root certificates, which are used to modify and inspect what should be private traffic. Thankfully you have control over what your browser trusts.
5. Ability to send passwords in newer browsers
Current Firefox nightlies, and soon Firefox stable, add warnings to pages that use
password type inputs without HTTPS. Here’s what it looks like:
If you’re not already considering HTTPS a standard part of your web app development cycle, you should be.

What is Data Visualization?
Data Visualization is a way of representing complex data and stats in a pleasing, visually-appealing way. Visual data may include components like pie and graph charts, maps or tables, and can be presented in different forms, such as infographics, videos, illustrations and interactive reports.
Why is it important? The answer is simple. Our brains absorb visual information better, faster, more easily.
Benefits of Data Visualization
The benefits of visualizing data include:
- providing clearer information for clients
- making it easier to view and analyze patterns and trends
- enabling interaction with the data
- allowing for more information to be absorbed, and more quickly
- better identify peaks and troughs.
Sitepoint’s arcticle is going to assess how a new tool, Google Data Studio, can help us build beautiful and interactive reports.
Google Data Studio
Google Data Studio (GDS) is a new tool by Google that makes it easy to create beautiful, engaging, responsive, branded and interactive reports. It does this by pulling metrics from Google’s properties, such as Google Analytics, Adwords and YouTube Analytics, as well as spreadsheets and SQL databases.
For the article, the author will be using Data Studio to create a visual report using Google Analytics data. To do this, you first need to have an active Google Analytics property that is properly integrated with the website.
The same applies to other reports. If you wish to pull the data from your Adwords or YouTube Analytics, make sure to sign in with an appropriate Google account that has that data.

The purpose of Shiny is to provide an intuitive and user-friendly interface to R. R is a highly popular statistical environment for doing heavy data analysis and constructing statistical models, and therefore is highly popular among data scientists. However, for a user with a non-coding background, using R to conduct such analysis can become quite intensive. This is where Shiny Web Apps come in. Essentially, Shiny allows for a more intuitive graphical user interface that is still capable of conducting sophisticated data analysis — without the need for extensive coding on the part of the end user.
In this article on using Shiny with R and HTML, the author illustrated how an interactive web application can be created to conduct analysis without the need for direct manipulation of code. In this article, the author will use a slightly different model to illustrate how the Shiny environment can be customized to work with the end user in a more intuitive fashion. Essentially, the goal of this article is to illustrate how a user can:
- Build an application by linking the UI and server side
- How to customize the themes available in the Shiny Themes library
- Implement error messages in order to provide guidance to an end user on how to use a particular program
The program itself that is developed for this tutorial is quite basic: a slider input allows the user to manipulate a variable within the program by means of reactivity, which causes instantaneous changes in the line plot output that is developed by means of reactivity.
This inherent function gives Shiny a significant advantage over using R code as a stand-alone. Traditionally, in order to analyze the change in a particular variable, the code must be manipulated directly (or the data from which the code is reading), and this can ultimately become very inefficient. However, Shiny greatly speeds up this process by allowing the user to manipulate the variables in a highly intuitive manner, and changes are reflected instantly.
However, the whole purpose of Shiny is to make an R Script as interactive as possible. In this regard, the user will want to be able to add features to the program that go well beyond reactivity. Two such aspects of this that the author will discuss in this tutorial are:
shinythemesin order to customize the appearance of our Shiny appearance
- Constructing a
validate()function in order to display an alert once variables are manipulated in a certain manner
