Getting Ready For HTTP/2: A Guide For Web Designers and Developers

The Hypertext Transfer Protocol (HTTP) is the protocol that governs the connection between your server and the browsers of your website’s visitors. For the first time since 1999, we have a new version of this protocol, and it promises far faster websites for everyone.

In this article, we’ll look at the basics of HTTP/2 as they apply to web designers and developers. I’ll explain some of the key features of the new protocol, look at browser and server compatibility, and detail the things you might need to think about as we see more adoption of HTTP/2. By reading this article, you will get an overview of what to consider changing in your workflow in the short and long term. I’ll also include plenty of resources if you want to dig further into the issues raised. My aim is to give you enough of the background to be able to make good decisions as you plan your move to HTTP/2.

A Brief History Of HTTP Link

HTTP is an old protocol, initially defined in 1991, with the last major revision — HTTP/1.1 — published in 1999. Websites in 1999 were very different to the websites we develop today. In http2 explained, Daniel Sternberg notes that the amount of data now required to load the home page of an average website is 1.9 MB, with over 100 individual resources required to display a page — a “resource” being anything from an image or a font to a JavaScript or CSS file.

HTTP/1.1 does not perform well when retrieving the large number of resources required to display a modern website. As we’ll see later in this article, many of the performance best practices we know as web developers come from our coping with the limitations of HTTP/1.1.

How to Troubleshoot a Computer

When your computer misbehaves, it’s useful to know how to troubleshoot problems yourself. That way you won’t have to run to the computer repair store for every issue that arises. There are a variety of things that could be going wrong with your computer, but you can usually track down and fix the problem on your own.

1.Reboot your computer. It may seem like a simple suggestion, but rebooting your computer will fix many of the problems you may be having. Press the Power button or use the Shut Down command to safely turn the computer off. If the computer is not responding, press and hold the Power button for about five seconds to force the computer to power off.

• Allow your computer to sit for about thirty seconds after being turned off before you turn it back on again.

2. Try to determine what caused the problem you are having. Think back to when the computer started having issues. Was a certain program installed, or a change made to the hardware? Was something suspicious downloaded, or installed with a program you got? Was there a power outage and now things aren’t working correctly? Narrowing down the possible cause of the problem will make it much easier to determine how to proceed.

 

 

 

 

3. Check all of the cables. A loose power cable could be preventing your computer from booting up. A bad surge protector could be the culprit. Your keyboard or mouse may have come unplugged. Your monitor cable might be loose. Checking all of your connections will only take a moment.

How Safe Is Online Backup?

In this article, we will take a closer look at how safe is online backup and which are those different security elements that define safety. Let us clarify first that uploading data to an online server doesn’t mean that it will become automatically visible to everyone. Modern online data backup services protect your data with multi-layered security, which means high-grade encryption, sending data over secure connection, saving data in encrypted format, servers’ duplication and extremely high level of physical security of servers.

Online Backup Means Additional Safety

When your files and folders are saved locally, you have a quite high risk of losing them. Imagine hard disk failure, computer viruses, thefts, fire and flooding accidents, deleting files by accident or overwriting them unwillingly. If you have no backups, you will lose your valuable data forever. Having data backup and keeping it in remote location gives you security, and you will not lose your important data due to a sudden, unexpected event.

Data Safety with Encryption Technology

The best online data backup providers offer twice as secure encryption as the leading payment gateways. If you trust Paypal and Amazon with 128-bit encryption technology, the leading online backup services, for example Backblaze, Livedrive, ZipCloud and MyPCBackup, are offering even more secure solutions with 256-bit encryption. This gives even higher guarantee that your files and folders are sent safely and nobody can hack or interrupt sending data to backup server. All listed online backup companies are using the same encrytpion standards for transferring your data from a server back to your computer, so both sending and downloading backup data are secured in the same way.

Additional Encryption on Backup Server

Online data backup service providers are doing their best to keep your files and folders safe. The best online backup companies are also offering additional security layer, and are compressing and encrypting the data from server-side. Typically, server-side encryption is done with such advanced technologies like AES or Bluefish, which are both literally unbreakable. Compression helps backup firms to save some disk space and optimize their expenses, so that they are able to offer you services with reasonable prices. Server-side encrytpion gives additional guarantee that there is absolutely no chance for other clients, hackers or rogue employees to access your data.

All server rooms have cooling and other climate control equipment, automated fire detection and suppress systems. Most importantly, server rooms have uninterruptible power supply, from multiple electricity sources, for case of outages. With backup companies, servers are protected against many possible accidents you haven’t even thought about. Professional online backup service means that your data is always protected.

Multiple Hard Disks and Locations.

 

Top data backup companies have multiple server centers located in various geographic areas. Your files and folders are copied at least to one other hard disk, in another server. It means that if something happens with the main disk and server, your data is safely preserved in another location and can be recovered from it. Data duplication to additional geographic location adds to the whole backup system another safety dimention, which gives you additional guarantee that your backup copy will be available when you need it the most.
