Mean Stack Technologies

Developing websites with the help of Mean Development Tools is very advantageous than other tools as it provides greater amount of flexibility than other tools. It feeds upon the JavaScript language for coding which makes integration with other applications quite easy. The vision of the Mean Stack development technology is to enable developers in creating more agile applications with uniform language at all the layers.

MongoDB database shares a remarkable similarity with other databases but it is schemaless which makes additions and deletions quite easy. This aspect and feature of the MEAN development technology eliminates complexities and redundancies while dealing with large amount of data. It is very difficult to deal with data segregated into tables and columns in SQL databases. This function also makes MEAN based development synchronized with cloud and cloud based applications. Therefore, the cloud based applications can be easily created and hosted on the cloud network.

MongoDB is also a good alternative to the JOIN Command. It is true that the JOIN command is a groundbreaking innovation for saving disk space. With the help of this command a user can delete unnecessary fields. The fields can be included whenever a necessity arises. This feature concludes a cheap and clean database. But disk space is quite cheap nowadays and comes with terabytes of memory. So JOIN can be replaced with MongoDB.

Mean web development tool uses Angular JS as web client framework which runs at supersonic jet speed. It is a good option when compared to other frameworks like Apache or Internet Information Services (IIS). Apache and IIS lack multitasking abilities as they both conceive HTTP requests using threads. If the threads are engaged in different types of work than no further requests can be generated and this slogs the server response. Having good speed serves many benefits as today’s user are very restless and spend very less time.

During the development stage, the conventional web pages need to be refreshed again and again every time there is a request. So if there is huge data on an ecommerce website then the user has to click ‘Next’ to go to the next page. At this point, he again views the content he viewed earlier. This creates a bad user experience which can severely hamper the prospects of businesses. The advantage with Node JS in MEAN development is that it runs on only one thread for receiving incoming HTTP requests. It performs operations very instantly as it is capable of receiving threads very quickly. So it manages multiple connections at one single point of time. The PHP fan club might boast about the code libraries developed for leading platforms like WordPress or Drupal. However, Node JS is a complete package manner for which the public libraries are increasing at a flash flooding pace. In the coming days, it is possible that many more platforms will be developed using Node.js.

Another amazing option available with MEAN development stack is Express JS which renders vital resources for executing similar and identical tasks on the website. Its interface is quite simple which allows a user in creating endpoints and managing cookies. Moreover, it helps in creating REST routes; for managing HTTP Header; providing supporting to integrated middleware for effectively managing the requests and responses.

All the critical elements of MEAN web development tools (MongoDB, JS Express, AngularJS and Node.js) speak JavaScript Object Notation (JSON) for transferring data. The fluid data in JSON remains very crystal clear while moving through different layers. JSON eliminates the requirement of reformatting the data again and again for every layer. Whereas, the PHP language which reads the SQL data doesn’t support the data at every layer.

Breaking Changes in Selenium

Like any good software developer, we tend to treat breaking backward compatibility as a crime and work hard to protect our end-users from facing any consequences resulting from unexpected changes. That said, we live in a world where change is the only constant! It’s always a challenge to absorb the changes.

For our Scriptless Test Automation platform, we use Selenium WebDriver to interact with the Browsers. We generally use a stable version of Selenium webdriver as a base line for our own development. However, we end up supporting multiple versions and combinations of supported browsers/OS combinations, as our customers demand it. During the regression phase of a particular product update release, our QA team reported an issue that all the mouse actions (MouseHover, MouseUp, MouseDown) were not working with the Selenium WebDriver version 3.6+

We investigated the issue and figured that inside mouse actions (in the Qualitia Engine code), we use Locatable APIs. We found that these Locatable API had been refactored (as well as deprecated) by Selenium community in SE 3.6+ and the community recommended to use Actions API which they supported since SE 3.0+.

Though the challenge, henceforth, was going to be maintaining backward compatibility with Selenium versions in Qualitia (at least post SE 3.0), any of the above changes would be simple if we didn’t care about backward compatibility. But then ideally we have users using various Selenium 3.x versions. We had no option but to fix this issue in Qualitia 5.0 in a manner which works across all the Selenium 3.x versions.

We also figured out that Locatable is a primitive way of accessing mouse actions so the community was forced to move to Actions API and hence, they didn’t care refactoring them. This essentially caused breaking changes. After brainstorming, we could come up with a few approaches as solutions for this issue:

Potential Solution 1: The seemiingly obvious solution was to replace Locatable package statements with new package structure statements (which SE 3.6 had introduced) and compile the code with Selenium 3.6. The code would have successfully compiled. However, it would have thrown runtime exception for those mouse actions (MouseHover, MouseUp, MouseDown). This would happen since Java wouldn’t find the package structure in earlier versions, which is meant for SE 3.6. We dropped this solution.

Potential Solution 2: Use Locatable APIs and write code to handle Mouse actions in Selenium version in an agnostic way. The idea was, if mouse actions fail at runtime (due to unexpected package import) catch that Exception (which means user must be using pre-SE 3.6 version) and explicitly call the Pre SE 3.6 package structure (i.e. older fully qualified Locatable package to invoke Mouse actions on Pre SE 3.6).

The pseudo code would look something as follows:

try
{
//SE 3.6 handling
Locatable driver = (Locatable) webDriver;
Mouse mouse = driver.getMouse();
mouse.click(getCoordinates());
}
catch(RunTimeException e)
{
//Pre-SE 3.6- handling
com.newstructure.Locatable = (com.newstructure.Locatable) webDriver
Mouse mouse = driver.getMouse();
mouse.click(getCoordinates());
}

This Selenium version specific exception based code and using deprecated Locatable didn’t seem to be clean and promising way. Making Selenium version assumptions for the run-time exception can turn anytime into a disaster.

Potential Solution 3: Use Actions API and change the entire implementation while maintaining the backward compatibility. Since Actions API is supported post 3.0+, it would be very safe to use them. Moreover, SE community also recommends to use them over primitive way of using Locatable mouse action. We also achieve backward comparability. There would be almost no impact to the Qualitia user, since for her, in her scriptless Qualitia steps, mouse action name and parameters would remain the same. (Although, technically speaking, the parameters would get ignored in the latest API, but that won’t break anything for the user.)

We decided to go for Solution 3. For the Qualitia User, nothing changes as we decided to live with optionally accepting the parameters, which are not used by the API. The old test cases will continue to function without any impact. The Qualitia user would blissfully be unaware of the changes happening under the hood!

Business Process Automation

  • Fully Identify The Needs Of Automation. What workflows and tasks exactly do you want to automate in your business? What specific performance figures do you want to improve? Ask yourselves these questions before deciding which automation tool to apply.
  • Make A Checklist Of Features Needed. Depending on your business purposes and goals of automation, your automation software should embrace a number of specific features you need. Do you want to make your marketing efforts more efficient? – Make sure, your tool is able to improve lead generation and build initial contacts with your customers.
  • Strive For Cohesiveness. Make sure, your newly chosen automation tool is capable of easy integration with other systems. You use a lot of digital tools for business running purposes, so don’t let them work against each other. Otherwise it could disrupt the whole workflow process and cause more harm than good.
  • Fully Realize Your Navigation Capabilities. Ensure, you and your team will be able to navigate the software without difficulties. If you can’t easily set up and use your solution, then most of the time saving advantages will be just negated.
  • Ensure Your Software Will Grow Along With Your Business. Think long term and find a solution, which can scale along with your constantly advancing business. Make sure, your choice is agile enough to grow and adapt to the future needs. So you will not have to worry about outgrowing its features and necessity to switch over to the latest software.

Dedicated Leased Line

Apart from that, dedicated lines are mainly used in carrying out phone calls and providing enough bandwidth to the head office of a company wherein various staff can be connected to work computers down to home.

More so, dedicated leased lines provide a higher data throughput, more consistent speeds, and faster upstream speeds. They also make certain that the capacity used is reserved primarily for the use of an individual company. As compared to connections on consumer internet, the bandwidth that is available is not expected to drop at the most needed time when customers also attempt to use the connection.

Dedicated lines also provide great speed advantages, not like ADSL. Based on the research in the United Kingdom Telecoms industry, an ADSL connection provides only twelve megabytes downstream and one megabyte upstream.

On the contrary, an Ethernet circuit with a higher capacity may provide a speedy connection of almost ten-thousand gigabytes, both downstream and upstream. Some companies are not in need of enough bandwidth; others are in need of more bandwidth which ADSL cannot deliver.

Dedicated connections may also deliver more consistent and higher speeds compared to broadband. The only difference is felt in the speed of uploading. Due to the reason that the connections of dedicated lines are symmetric, the speed in uploading through the connection is perfect that meets the download speed. For a lot of businesses, a much slower speed in uploading results for upgrading the efficiently-built dedicated line.

More so, dedicated lines have their faster and better service agreements. Dedicated lines service agreements often guarantee that if connectivity issues arise, they will be fixed immediately in just one day. They also increase their service by actively monitoring the connections twenty-four seven every day. This further ensures that once the line has gone down, the operations center will troubleshoot it. In effect, the downtime is further minimized.

On the other hand, the dedicated circuits can further carry the WAN traffic, telephone calls, and video conferencing streams. Various types of traffic can be carried out which range from the internet traffic like emails, web pages, and even video streaming.

In addition, dedicated lines may also be used for carrying out telephone calls as many companies are connecting telephone systems to the telephone network through the use of ISDN30 circuits. The typical speeds also range from ten megabytes, twenty megabytes, and one-hundred megabytes.

Truly, dedicated lines are a lot better compared to ADSL for most businesses!

What is a leased line?

A leased line is a private telecommunications line that permanently connects two locations to provide reliable, guaranteed bandwidth for data, internet and voice services.

Leased lines provide symmetric bandwidth, meaning that the upstream and downstream speeds are the same. These speeds range from 10Mb right up to 10Gb.

When selecting your service speed you also select a bearer speed which is the maximum your line can carry in the future. So when receiving a leased line quote you will see figures quoted such as 10Mb on a 100Mb bearer – which means you are taking a 10Mb service on a 100Mb bearer.

At any point in the future, you can increase your speed to 20Mb, 30Mb right up to the limit of 100Mb.

Typically there are three main types of leased line connection:

Connection type 1

A connection between a customer location and a Point of Presence (PoP), which is typically used for access to the Internet;

Connection type 2

A point to point (P2P) connection between two customer locations linking them both together for data upload/download.

Connection type 3

A connection between a customer location and a data center. Whilst the majority of leased lines we supply are for internet access, we also provide them for MPLS Networks and direct P2P (point to point) connections.

About Uncapping Cable Modems

Uncapping is defined as the concept of somehow eliminating the bandwidth limit many cable modem service providers impose. Some customers want to do this in order to improve the speed of their cable modem. This is obviously theft of service and may have seriously unpleasant consequences like imprisonment.

One way to do this is to set up a modified DOCSIS config file on a TFTP server hooked to the Ethernet side of the Cable Modem and tricking it to read the config file from the Ethernet side instead of the cable side. There are other ways but it involves highly technical skills in server technology and is too risky.

Cable modems service providers are fighting back with MIC, MAC/IP Checking and DOCSIS 1.1. MIC. Message Integrity Checking is run by authenticating the config file in the modem through robust encryption techniques using a shared secret. MAC/IP Checking is run through the service aggregation device (router) that checks the matching IP addresses with MAC addresses that were assigned to the end user PC during DHCP or statically. This would prevent the IP Accumulation attack way of uncapping. If the BPI+ of DOCSIS 1.1 is enabled, the Fake MAC way of uncapping would be consequently prevented. Most MSOs have not yet upgraded to v1.1, but that is expected to happen over time. Problems with theft of service may influence the decision to upgrade.

Rapid Application Development

An astounding 65% of the budget of large firms is spent on maintenance and upgrading its operating systems. These were designed only some time ago, but given the nature of alterations and their frequencies, many software require changes and transitions. Quite often, the end users can satisfactorily meet all their requirements even without some essential components of a software. It is the task of a software developing team to identify all such potential areas of operation which can be left out or encapsulated within a broader heading, to save the time, effort, and cost. In some other cases, the business which has ordered the software can negotiate on certain parts which can be done away with, before the software is fully developed. It may again save valuable cost and time before implementing the software.

RAD is a combination of entities like a well-defined methodology, a dedicated and trained staff, proper and efficient management practices, which uses both efficient manual and computer tools. The entire system of operation can be summarized as a software development mechanism providing higher quality in less time, using:

  • Software essentials restructuring
  • Prototyping and verification designs
  • Integrating all changes in the current model
  • Minimizing the effort of reviewing, testing, and other such steps

Advantages of Using RAD

There are many advantages of using RAD, and it can solve many concerns of the user as well as the developer.

  • Conventional software development methods take, on an average, almost 20% more time than the RAD procedure. Using RAD can enable quicker visualization of the end-design, and hence, allow rapid software testing and rectifying steps. The customer is able to have a faster look at the design to add valuable inputs, in order to make the design more user-friendly.
  • The current competitive scenario demands frequently upgraded software in order to effectively satisfy customers’ requirements. RAD enables a faster and updated version to reach the end user, by systematically eliminating redundant steps or using the prototype methods.
  • Cost overruns and meeting the time constraints are another advantage, though not a big consideration in high-end uses.
  • RAD makes the development process to be a more credible one by facilitating a scope for the customer to actively provide inputs and feedback in the development process. This may also prove feasible from the point of view of a developer.
  • It protects the current project from being subjected to variations in the market.

 

Logistics Product Data Training

As a supplier, if you’re unsure concerning the quantity placed by means of a customer and you invest a massive amount of inventory. Most often, in the event the customer cannot get the information that they desire in a timely fashion, they will move on to some other online company and buy the things that they want there. If he doesn’t want the product that arrives, returns increase the cost of operation. Since customers are the best assets in the company, with their feedbacks, business will adjust their operations to fulfill the ongoing needs of their subscribers. By identifying which type of customer is targeted, the grade of the procedure and the output itself will be streamlined. With the internet advantages of payments and orders, several customers are given extra convenience to make the most of their time.
Introducing Logistics Product Data Training

Each organization differs in its attitude towards customer support. Perhaps among the most important departments in regards to taking the organization to the next degree of innovation! It is essential to every business organization to comprehend the customer needs for value-added service.

However great the new product may appear, in the event the market rejects it, it is a failure. Without the demand for a better mousetrap, no one builds one, even if this need is simply locating a new product to generate income with. Within this role, you will make certain that the ideal products are delivered to the correct location in time and at a very good price tag. Attitudes and Usage Studies track how folks interact with products and supply insights concerning this usage. The breakthrough product is something which is entirely new.

There are steps a business can take to enhance the probability of a prosperous development practice. For every single item, companies ought to be in a position to find the perfect price a customer is prepared to pay. If a business has numerous problems that will need to get addressed, a consultant may be required long-term. In this way, it needs to only stock products as per demand. Most companies won’t have this highly specialized skill in-house in the advertising department.

Desktop Security Software

Before You Go

Be sure to install all of the latest security patches.  This should include your OS and third party applications (chat, PDF viewer, browser, etc.).  As part of this, make sure all of your desktop security software, as well as the software you use normally, is up to date.  This will guarantee protection against any threats you may encounter on a public WiFi connection.

As tempting is it may be, it is best not to mention anything about going on vacation on your social network of choice.

Make a backup of your computer.  This is one of our ten rules to keeping your system secure, but make sure you definitely make a backup before you leave.  Should you get some sort of infection while out and about, you will be able to enjoy your vacation much more if you know the contents of your disk are safe at home ready to restore when you get back.

If you haven’t already done so, encrypt or password protect your data and/or any data devices you are taking with you.  Just like pickpockets hang out in crowded tourist areas, hackers look for chances to exploit unprotected public WiFi.

During Your Trip

Most people who travel with a laptop are very quick with the computer usage they need.  Usually, they just need to log in quickly to check and send e-mail.  Because of not wanting to be on the computer too long, you may be tempted to bypass any virus definition updates from your antivirus or other security software.  Because new threats are flagged everyday, please, don’t forget your updates.  This is a must!

If on an unknown network where you are unsure about the security of the connection, do not enter personal details such as credit cards or passwords.  If you want to be extra careful, disable autostart for programs that use the internet to log on with a password (Skype, MSN, etc.).

In addition to the above, avoid Internet banking on networks that are not your own.  This even includes your hotel.  Just because they have high speed Internet does not mean that it is secure and virus free.  If you have kept your security software up to date, your system should catch any threats.  But why risk it?  If it is really necessary to do business while away, invest in a portable wireless option from your Internet Provider before you go.

Because flash drives and other USB devices are a common source of malware infection, turn off the “Autoplay” option in the control panel.  Another suggestion is to give each one a quick scan with your antivirus or anti-malware software before opening any files.

Optional:  Change your wireless network settings and avoid connecting to unsecured public WiFi.  This can be done from the control panel at “Network and Internet Connections.”

When You Get Back Home

Scan and patch the computer you work on, if it should be different from the one you had on your trip.  Remember, as long as you have been away, it has been sitting there, collecting dust on its virus definitions and other security updates.  This is a pain on a busy day back in the office, but know it will be part of your first day back and schedule it in so you don’t skip over it in a rush.

Finally, you probably took some pictures.  Maybe you took a lot.  You will also probably want to share those pictures.  However, JPG files also have an EXIF field that many are unaware of.  If you took these pictures with your iPhone or other smart phone, this field will have GPS coordinates.  This is not necessarily a concern for everyone, but say you were staying in a vacation home that you or a friend owns.  Some one could find this picture online, see your comment how the vacation house now has a new TV, and find out exactly where this unoccupied house is from the JPG.  For more information, learn how the EXIF field can be  cleaned.

Safe and digitally secure travels!

Things to Consider Before Going for Web Development

  • I. Domain Name: One of the basic things before starting with web development is choosing a name that people can remember well and easily. Along with it choose wisely and appropriately, whether you will be using.com or.net, or something else.
  • II. Hosting Provider: The speed and working of your website would be dependent on the hosting service you choose. So it’s always recommendable to choose a reliable hosting service provider and look at how much capacity you need and thus accordingly choose one which suits your needs.
  • III. Latest Technology: Always keep in mind to use the latest technology for web development like HTML5, CSS3, PHP, JQuery, JavaScript, etc. Nowadays, all web development companies use the best and latest technology.
  • IV. Colour & Layout: An eye-catchy color can always be termed as the best option for your website. As it’s said that colors affect the feel of your website, it is best to choose the best color for your website. A neat & clean layout is always preferred by visitors. And not to forget about the header and footer. It must be attractive, but at the same time even simple and not too shiny.
  • V. Have clear Purpose: Now when you have started the process of web development, you must have a clear and precise idea regarding it.
