How to Improve Website Performance Without Harm

If you want to make your site popular among internet users, you should do your best to speed it up. There are quite a lot of ways how you can do this. For instance, you can find an appropriate hosting plan.
However, it’s not the only way you can choose to accelerate your site. Today, we’re going to give you more tips how to make your web platform a speedy one. So let us start.

Tip 1: Make Sure that Your Code Is a Proper One

If you’re willing to create a website, you need to write a code for your web pages. Remember that writing a tight code can help you accelerate your site immensely. So what things can help you write a tighter code?
  • You can save more than 50% on file size if you use pure CSS instead of tables;
  • Get rid of excess code in CSS and JavaScript;
  • Transfer CSS and JavaScript files to external files;

Tip 2: Use a Content Delivery Network (CDN)

Using a CDN can really speed up your site, as this service unites a chain of data centers (Points of Presence or PoPs) where your cached and copied content will be stored.
Such a simple decision gives you an opportunity to deliver your web files to their end users from the servers located not far from their place of residence at a high speed. Besides this, a secure CDN also gives you an opportunity to:
  • Reduce load on your initial server;
  • Cut down your hosting expenditures;
  • Continue delivering your web content even if the initial server shuts down;
  • Protect your content from hotlinking, scrapers and other kinds of malicious bots.

Tip 3: Apply for Caching

Caching can also help you make your web pages smaller. For instance, you can put some extra tags in the header to to monitor how pages are cached. If you have the pages that don’t change, you may add a ‘never’ value to the ‘Expires’ header. You can also specify how often pages should expire.

Tip 4: ‘Squeeze’ Your Images

Images often contribute to the design of the website. However, they need a lot of traffic to be downloaded and finally slow down your site. Here are several tips how you can optimize your images:
  • Use a special software to cut down the size of the palette of GIFs;
  • Transfer your GIF images into PNG images to be able to use PNG optimization software;
  • Resize your images with the help of an image editing program.

Today, we have given some clues and tips on how to speed up your website. We hope that our post will help accelerate your site effectively.

Most In-Demand Programming Languages in 2017

There are great many of programming languages, some of them are more popular among developers, and some are less. In order to be competitive and informed on the latest market tendencies in the sphere of programming, we provide you with the list of top-5 popular programming languages that are in demand in 2017.

The language
Language description
SQL - Structured Query Language
This language has won a dramatic lead over other programming languages in recent years, thus, SQL is a clear leader in our list. The language is used in order to communicate with and manipulate databases. The language is common with many variations like MySQL and Microsoft SQL. Moreover, the language has become more open with the popular data analysis programming language, and a Linux version.
Java
The number of Java positions, available in the market has gone up by almost 30,000 in 2017, probably due to continuous Android growth. This is a simple, widely-applied language, used by millions of developers worldwide – all native Android apps are built in Java. Moreover, we remind you about the upcoming Java 9 launch in July 2017, this event will, supposedly, contribute to the language popularization with general public.
Python
Being a general purpose programming language, it emphasizes code readability and, increasing developer productivity, used for desktop apps, web apps and data mining.
JavaScript
This, mainly client-side and dynamic scripting language, is used for front-end development. The programming language is compatible across all browsers, used in over 90 percent of all webpages.
C++
C++ is based on C – the “grandfather” of all programming languages. C++ appears to be a powerful, high-performance programming language, used to develop system software, games engines, desktop and web apps. At the same time, many beginners admit that C++ is harder to learn that Python or JavaScript, for example.

What do we know about SNMP?


What do we know about SNMP?
First of all let’s clarify what this abbreviation stands for. SNMP stands for “Simple Network Management Protocol”, it is an internet-standard protocol, which collects and organizes information on managed devices on IP networks in order to modify that information to change device behavior. The main application of SNMP is in network management for network monitoring.
Surely, it is a real challenge to manage large network with many nodes without a large staff to monitor every computer. With the help of SNMP or network system monitoring you can monitor network nodes from a management host. You get the chance to monitor network devices, such as workstations, printers, routers etc. All you should do is to install SNMP on the network device you intend to monitor.
Scan SNMP enables network devices by entering IP ranges to be scanned. Each device possesses its own unique webpage listing device details such as name, MAC, IP address, vendor, model and serial number. Device specific information is also scanned in the form of a complete network interface for switches and routers or toner information for printers. In order to identify your devices MAC addresses are used. If IP changes occur, your device entries are simply updated.
More possibilities
  1. You can make manual changes as well
Nowadays modern technologies allow users to conduct information scanning automatically, but sometimes manual editing and adding entries become necessary as well. It is possible to edit manually a single asset or to change the information for multiple at a time. You can surf to any device's webpage and edit its scan results.
  1. Access device overviews
The SNMP inventory overview helps you find easily the devices you are searching for. You can custom sort devices by IP range or look for specific devices.
  1. Track the statuses

SNMP scanning retrieves toner information on your printers, and let’s admit that it is quite a valuable feature in busy office environments. Built-in reports are available to notify you of printers low on toner which in turn enables you to order new cartridges and schedule maintenances.

What is SDN (security-defined networking)

Software-defined networking (SDN) is an approach to computer networking that allows network administrators to manage network services through abstraction of lower-level functionality.

Originally, SDN focused solely on separation of the control plane of the network, which makes decisions about how packets should flow through the network from the data plane of the network, which actually moves packets from place to place.
Here is standard SDN framework:




We are using SDN, because of:
  • Direct Programming;
  • Centralized Management;
  • Reduce CapEx;
  • Reduce OpEX;
  • Deliver Agility and Flexibility.

SDN delivers speed and agility when deploying new applications and business services.

Forward networks and network protection


A team of PHD researchers from Stanford University, launched their new startup - Forward Networks, that help users understand network behavior while protecting and predicting how changes will impact the system.
There are 3 applications:
-Forward Search: Erickson describes it as a “Google search for your network.” It creates an inventory of all possible routes that traffic can take in the network. Previously this would be done through a cumbersome manual process of mapping packet flows or using a ping and trace routes. Forward Search allows users to precisely examine how traffic is flowing within their network between any two points.
-Forward Verify: This application explores whether the network is doing what it is supposed to be doing. It can test policies, such as isolation zones, which applications communicate with one another and even lower-level network “hygiene” policies related to optimized traffic flows.
-Forward Predict: This feature lets network engineers test a change they want to implement in their network in this software copy of the network before it is rolled into the production environment.

Will it change our ways to work with networks? If they will realize all these ideas, I think - yes.
