To dramatically reduce page load times, improve performance, and reduce your bandwidth and infrastructure costs, you can implement a CDN, or content delivery network, to cache these assets across a set of geographically distributed servers.
In this tutorial, we’ll provide a high-level overview of CDNs and how they work, as well as the benefits they can provide for your web applications.
What is a CDN?
A content delivery network is a geographically distributed group of servers optimized to deliver static content to end users. This static content can be almost any sort of data, but CDNs are most commonly used to deliver web pages and their related files, streaming video and audio, and large software packages.

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.

How can I make use of 1Password?
1Password is free to download and use, though some of its more advanced features will cost you money. Premium features can be unlocked for a one-time $9.99 purchase. Additional functions include:
- Additional categories (in addition to passwords, credit cards, and personal IDs)
- The ability to create custom fields in a stored item
- An Apple Watch app
- One-time password generation (available only on supported websites)
- Custom password organization and tagging
- The ability to create multiple storage vaults
A family plan with access for five people costs $4.99 per month and is billed annually.
The FDA (Food and Drug Administration) has released the well known standard 21 CFR PART 11, which governs how affected systems should handle electronic records and signatures. The scope of this standard extends to all companies within the food, clinical or pharmaceutical industries.
The question is if a web-based training system (also called Learning Management System or LMS for short) is required to be compliant with Part 11 or not. There is no clear answer to this question however; just as it is the case with any type of system (be it web-based or not) it depends on two main factors:
- What the system is/will be used for.
- If the system’s output (electronic or paper) will be used as official records.
If the system is/will be used to train employees and the electronic records of this process will be the proof of completion, compliance with Part 11 is required.
On the other hand, if compliance is not required, it may still be a good idea to verify if the employed system would confirm with Part 11 or not. The standard itself was created for the purpose of information security and the general requirements of confidentiality, integrity and availability (also known as CIA) are represented in it. The same view is employed here as is in many standards regarding information security.

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.

“You’ve designed a beautiful site. It looks great, it sells widgets, and it gets the job done! But, there’s always room for improvement, especially on the technical side of things. One of the best ways to improve the overall experience on your site is to enhance your site speed.
Besides making the experience better for your users, page speed is also becoming a major influence on search engine optimization. So, don’t downplay the value of page speed, even if your site is pretty fast already. Look at how fast your competitors are loading and you may find the quick way to get ahead of the search engine curve — faster sites get preferential treatment.”
10 ways to speed up:
- Faster Servers Mean Faster Results
- Turn on File Compression
- Put Images into CSS
- Minify CSS
- Minify JS
- Minify HTML
- Proper Image Sizes
- No CSS @import
- Browser Caching
- Clean Up Bad Requests
Quality and quality assurance is an ever present requirement in today’s world. In the field of programming, the management of code quality is a key issue in larger project, especially in cases where several programmers work on a project. Each programmer brings his or her own knowledge to the project, including their own coding style and solutions. While this can be a good concept locally, the whole project can become confusing and unmaintainable.
Luckily this is not a new issue and several solutions have been created for it. Static analysis tools is a collection of such solutions. They include standardization of coding and error detection.
For the list of static analysis tools for PHP, visit the following page: https://github.com/exakat/php-
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”.

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!
