IT-literature


Educational literature (textbooks, educational-methodical manuals) is one of the main means of presenting a material to students. It forms the basis for the formation of competences of educational institution's graduates, on the basis of their independent acquisition of knowledge, skills and abilities in their professional field, and experience of creative activity. Therefore, the level of university graduates' education, the quality of vocational education they receive, and hence their competitiveness in the labor market, largely depends on the quality of educational literature. 


IT educational literature is a very broad concept that includes both professional literature for IT professionals and books for beginners, i.e. people just mastering the computer and the Internet.


There is a program educational literature, i.e. literature for IT students in a particular discipline, and educational literature for those who study this field of knowledge on their own or strive for continuous excellence. After all, as you know, one of the fundamental commandments of a successful programmer is to never stop learning, which is invariably associated with reading professional literature. 


it-literature


Professional literature for those who study IT covers such topics as databases and DBMS, design, software development and testing, system administration, languages, techniques and technology programming, computer graphics and web design, operating systems, etc.


When choosing literature, it is important to understand that in the age of IT-technologies a lot of pseudo-scientific literature appeared. Sometimes it is difficult to understand the quality of the material because of the rich choice, and there is no one to ask for advice. Often young people, developing in the IT sphere, are interested in what successful IT specialists read? What books do they recommend? The Pro-Papers turned to its experts for clarification and collected useful advice on a selection of educational literature for IT specialists and those who are just studying.


So, the IT-sphere is updated every year with new subject areas (for example, blockchain (cryptoindustry), machine learning, Internet of things (IoT)), programming languages ​​(Scala, Swift, Go, Kotlin, Rust, Solidity), frameworks to existing programming languages and professions (smart contract developer, blockchain engineer, big data analyst, Go or Swift developers, etc.).


In order to be constantly on the crest of the wave, specialists need to continuously learn new things. Books on IT, books with successful cases of industry leaders, articles on Internet resources, IT courses and specialized conferences help in the development and expansion of knowledge. Often, IT specialists read the literature in the original language, since foreign publishers set trends and usually translated books appear with a decent time delay.


IT-specialists read first of all, specialized materials and books on their subject area. If you are a Ruby, you will certainly know the "Ruby Path" book, if you are an experienced rubist, you must have read "Metaprogramming in Ruby 2" and "Effective Testing with RSpec 3", if you are a Go programmer, you probably mastered "Go Programming Language". There are also bestsellers on project management methodologies, team management or testing tools for project managers and testers.


Our experts cited the example of a relatively new 3 books, which, as it seems to us, are useful to read for IT-specialists regardless of specialization.


Git for a Professional Programmer

 

For over a decade, any teamwork with code in IT companies has been conducted in the version control system. Every developer knows about the Github service or analogues (Gitlab, Bitbucket). Confident use of such a tool as a version control system allows improving the speed of both personal and team work on a project. The book "Git for a professional programmer" will allow you to feel like a duck to water when working with versioned code. The book is useful not only to programmers, but also testers and project managers.


Grokking Algorithms

 

The book is about the basic, commonly used algorithms, approaches and data structures. The basic data structures and algorithms are given in the book, in detail and clearly written, and even illustrated with excellent examples. The book is suitable for beginners (not necessarily "mathematical mindset"), as well as developers with experience who want to refresh the memory of the basics that have been forgotten.


How Does Google Work

 

Excellent book, that promotes honesty, initiative and openness to everything new. Moreover, the initiative should not be punished in case of failure (as an example, an unsuccessful google wave project is given). The Google company encourages its employees to act - as in the modern world hypothesis testing is cheap both in time and in money. We need to check more and make prototypes. The ideology of Google within the framework of project selection is to support strong projects, to give up weak projects as early as possible, even if many resources have already been invested.


For ordinary users who want to acquire or improve computer skills, there are tutorials for working on the Internet or office programs.


It is important to remember that books on IT technologies are usually extremely practical, and therefore you need to "become a skilled hand" so that the material correctly settles in your head. So, if you only begin to study the IT sphere, remember that only with practice you can become a skilled hand at IT.


It is worth to experience examples from the book immediately in the process of reading. If a technology is completely new to you and you have never met it either in practice or in theory, then most likely you will not understand all the information in the book for the first time. That is why it is recommended to return to the book again after the first reading and some practice.


Read, learn and do not be afraid to discover something new. Only by working on yourself you can become a professional in your field.

wifi-improvement


As one of the most popular ways to access the internet, WiFi is now used the world over by the public and various businesses. Also known as a wireless network, this innovative technology has paved the way for internet access as we know it, allowing multiple devices to connect to a network using radio signals.


However, it relies on devices being in a certain range, and sometimes this can cause weak or inconsistent connections, depending on how far any given device is from a router. As such, here are some useful ways to boost your WiFi.


Quality Router

 

First and foremost, you will want to make sure that you have a good router to help you access the internet. To this end, you may want to consider investing in an 802.11ac router, which is one of the best types of router currently on the market. They tend to have a much greater range and speed compared to some of the older Wireless G or Wireless N routers.


You may also want to consider using decent, durable parts to connect your router to your computer and the wall outlet. There are plenty of specialist suppliers like RS which stock quality cables which you can explore at your leisure.


Placing

 

Where you place your router will also make a fairly significant difference to its overall effectiveness. Given that WiFi relies on radio signals being transmitted cleanly, it is important that there are as few obstructions as possible when it comes to finding a home for it.


So, putting it inside a cupboard or in a box will weaken it, but leaving it in an open space (preferably on a wall mount) should help to strengthen the signal and improve performance. It is also good to have it in a central position in the house/building, so that each room has good coverage.  


Wireless Channel

 

Your router should automatically connect to the optimal channel, but some channels are more crowded than others, and sometimes there may be a better channel which is less crowded. Routers in surrounding buildings can interfere with your WiFi if they are on the same channel, so it is well worth looking into how you can look at which channel your router is using and switch it manually if necessary.  


This should help to strengthen your signal and prevent any degradation in the WiFi's signal, prolonging its shelf life.


These are just some of the many methods you can use to improve your WiFi. Be sure to find whatever works for your individual network and you should see a great improvement.   


proxy-server-android


Android enables its users to configure proxy settings for each individual Wi-Fi network they have stored on their device. Some networks, particularly corporate or educational facility networks, require users accessing them remotely to connect via a proxy or VPN.


When you connect to a network for which you have configured a proxy, any internet browser and app that support proxies on Android (of which Google's Chrome is one) will automatically route your internet traffic through the designated proxy.


Note that If you need to hide your IP address, or you are trying to circumvent local geo-blocking, you should use a VPN instead. When you use a VPN, all of your device's traffic is sent through it. However, in addition to the aforementioned circumstances in which a VPN is required, there are many users who prefer to use a VPN for a variety of reasons.


The Proxy Menu


The following method should work for all modern Android phones. Note that many manufacturers customize the look and feel of their phones OS, meaning that things might not appear exactly as described here.


To begin with, open your Android's Settings menu. Then tap the Wi-Fi option to bring up a list of networks. On many devices, this option will be tucked away in another menu, usually Connections. Check the top of your screen for a search bar while in the Settings menu. Searching for ‘Wi-Fi' on there should get you where you need to go.


Make sure that you are connected to the network that you want to configure and long-press (hold your finger on) the "Modify Network" option. From there, tap on the "Advanced options" section to expand it. Select the "Proxy" option and you should be presented with three options; "None", "Manual", and "Proxy Auto-Config". The automatic configuration option isn't available on all older versions of Android.


Configuring Your Proxy Automatically


Perhaps your organization may have provided you with a link to a configuration file to help you set up your proxy. These proxy auto-configuration scripts come in the form of a .PAC file. If you choose the "Proxy Auto-Config" option, you will be prompted to enter the address of the .PAC file.


Some networks offer auto-configuration through the Web Proxy Auto-discovery Protocol (WPAD). However, Android does not support this. You will therefore need a .PAC address in order to automatically configure the network. For WPAD networks, you will need to speak to the network administrator to find the .PAC address, or the manual settings that you need.


Manually Configuring the Proxy


After selecting the "Manual" option, you will see a list of settings appear at the bottom of the dialog box. This is where you need to enter the settings for your proxy; if you don't know what those are, you should speak to the administrator of the network you wish to connect to. Alternatively, if you are trying to connect through a residential proxies service that you have paid for yourself, you should be able to get the settings from their website or support staff.


In the "Proxy hostname" box you will need to enter either the hostname or the IP address of the proxy you want to connect to. Hostnames are in the format of "proxy.example.com", whereas IP addresses will be in the form of "xxx.xxx.x.xxx". Then, you will need to choose a port number you want to use when connecting to the proxy.


proxy-server-android-1



If there are any websites that you want to whitelist, exempting them from your proxy and telling Android to bypass the proxy when communicating with these addresses, you can enter them in the "Bypass proxy for" button at the bottom. If you want to add more than one address to the list, separate them with commas.


Once you have entered all your settings, press the save button and you're done! Each Wi-Fi network stored on your device has its own individual Wi-Fi settings, so enabling the proxy on one network will not automatically enable it on the others. You will need to re-enter the settings for every Wi-Fi network you wish to use the proxy with.


Wrapping Up


Configuring a proxy server on your Android device is simple and straightforward. It is worth asking your network administrator if they have an auto-configuration file that you can use. Not only is this faster, especially if you need to set up the proxy on multiple Wi-Fi networks, but if this file is ever changed or updated by the network administrator, your device will automatically use the new settings. If you manually configure your connection and have any issues, consult with your network administrator or proxy provider.


hosting-project-1


It becomes extremely difficult sometimes to choose a compatible hosting service, especially when the market offers you a wide range of hosting solutions. It is challenging to decide whether to go with a VPS, shared hosting, or a dedicated server.


Shared hosting is no less than a family data plan, where responsibilities are shared among the family members. VPS, on the other hand, is just like an individual data plan. It's you who extend and upgrade your resources by paying for the service.


Analogy - Hosting Platforms


Shared hosting

 

Shared hosting forces all the users to share the available resources on a shared server. It includes everything from memory to CPU time to the disk space. A reliable hosting provider monitors all the shared servers for an uninterrupted supply.


VPS hosting


VPS is just like owning a condo. While you got a rental apartment as a segment of an entire building, you are still responsible for maintaining your rental property. Not all resources on a private virtual server (VPS) are shared.


However, the required portions of these resources are always available for you. This enables you to have more flexibility and faster load time. VPS allows you to have comparatively more resources as compared to a shared account.


Dedicated hosting


Dedicated hosting can be put into the scenario of owning a house. It's only you who has the access to all the resources available on the server machine and no other user account can interfere. Nevertheless, this type of hosting service does not come cheap.


Which would be appropriate for an online business project?

 

Shared hosting

 

A shared hosting enables more than one website to consume resources on a shared server. Due to the fewer resources available, it only serves the purpose for small websites and blogs where heavy traffic is not much a concern.


VPS hosting


VPS is the best way to start with, especially when you are running restricted on your budgetary limit. If you are a startup and want to share your business idea with the world, VPS can be your best pal. There are several hosting companies that provide this service.


You may like to go with Hostinger VPS plan as it is one of the many hosting providers that provides cloud infrastructure for their services. It is a perfect balance of both performance and cost-effectiveness.


User's point of view over VPS


1. Excellent performance and dedicated resources such as more CPU power, tweaked RAM, enough storage, and adequate bandwidth.


2. The isolated environment for better security and invincibility against getting affected by your neighbor.


3. Complete root access to the hosting server just like a dedicated hosting.


Advantages

 

If you are looking for a better performance, cheap in cost hosting, top security, and complete privacy - VPS can be your best option. Some of the advantages you'll get by opting for this service are;


1. More compatibility with regards to the resources.


2. Server setup takes less time.


3. More access to the server with better control.


4. Complete isolation in the environment where a VPS server functions.


5. Almost mimics the characteristics of a dedicated server.


Why switch to a VPS host?

 

1. When you need more speed


Adding more content to your website, most likely to slow it down after a while. This is nothing new when it comes to the websites that are more database dedicated. When you start noticing a significant reduction of speed, it's time to switch to a VPS host.


Furthermore, the majority of the growing websites witness an insurmountable traffic over the time. The more popular your website gets, greater will be your viewer traffic. It also signifies that your existing plan cannot bear the heavy traffic. Therefore, VPS would be more logical for you.  


2. When you lack with the resources

 

When your website continues to face 503-server errors, it indicates that your services are no longer available to your customers as well. It also points out that you are substantially lacking with the required memory on your server. Thus, the VPS upgrade is a must.


3. Insurgence in the security

 

If by any means you've opted for a faulty hosting service, part of which, you are constantly under the cyber attack, it's time to change it to VPS. Otherwise, it may result in data loss and a potential business fall as well.


4. Lack of features


Lack of features may result in less flexibility, uncertain downtime, and fewer viewers. On the other hand, a Cloud-based VPS offers more flexibility and compatibility in both open-source and proprietary Operating Systems.


What to look for in the best VPS hosting provider?

 

1. Live chat support

 

A trustworthy VPS provider enables you to have a live chat support for troubleshooting. The availability and lack of this feature make a whole lot of difference.


2. Cost


If budget is your major concern and you are looking for a moderate performance with regards to hosting, choose a service provider that offers you VPS plans at a cheaper cost.



3. Trusted source and uptime


You need to look for how much uptime your host promises you in your VPS hosting package. Like it or not, but it is one of the deciding factors with regards to the reliability of a service provider.



4. Customization

 

As mentioned above, your VPS service must be flexible in nature. Just in case you think your website requires more resources, the provider must be flexible to extend it with an upgrade.


Dedicated hosting

 

Dedicated hosting has its own fair share of advantages when it comes to the hosting solutions. It provides you the full access to your resources. It can be your best option if you have an established business and you look for extended resources to support your hosting solutions.


It, however, costs a little bit more as compared to the VPS hosting. Whereas VPS provides you with a moderate yet tweaked performance, a dedicated hosting provides you the same but in an extravagant way.


Conclusion.


While the shared hosting is good for the home users, the VPS is for those who wish to dive deep into the web world. Dedicated hosting also doesn't seem to be lacking anywhere as it offers you the heavy duty performance. However, for startups, VPS can be a great option.


workplace-leader


Being a leader in your field of work is what many aspire to be, although not all who have this dream will be fortunate to achieve it. While at the same time not all who move up the ladder necessarily become good managers either.


LEAD FROM THE TOP

 

Whether you are in charge of one person or one hundred, the pressure that comes with the extra responsibility of leadership is not something that should be diminished, especially as a businesses success or failure is usually dependent on the orders from the top.


In the pursuit of business success having a good workforce is only half the battle, it's what you can do with your staff which is key. Get the best out of co-workers and your company will go from strength to strength.


However, on the flipside should you not got manage to unlock the true potential of your staff then it means you could be in for a rocky period ahead. One that could lead to a set of personnel cutbacks somewhere down the road.


Many have asked the question, just what makes a good leader in the workplace and it is one that in fairness does not have a definitive answer. The simple reason being is that no two sets of staff are the same.


EVERYONE IS DIFFERENT

 

Every group of staff that needs to be led will come from a mix of different backgrounds and will bring their own personal attributes to the table, while at the same time there are a number of different managerial styles that can be applied.


Therefore, it is all about trying to get the two components to mesh perfectly in a bid to help your business prosper and even though there are a number of different permutations in the workplace there are some central staples that can be applied across the board in regard to leadership.


Most people will have the point drilled into them that work is the most important aspect of their life, something that is not strictly true. There's no doubting that gainful employment is a key aspect especially as it allows people to live their day to day lives.


Unless the work that is being worked on is one that is more altruistic in nature such as charity or volunteer work, the chances are you are going to need some financial inducement for the job that you carry out.


FINDING THE BALANCE


At the same time though workers need to be careful they don't become a slave to a wage and make sure that they find the correct work life balance in their job. This is somewhere that good leadership skills can be displayed.


If a staff member seems deluged with work, then here is the time to step in and address the situation. Perhaps take time to chat to that member of staff and allow them to raise any concerns about the current workload.


From here you can delegate some of that load to other members of the team. It could be you have an excellent worker who cannot do their job to the best of their abilities due to them getting bogged down with the more unimportant facets that they have to deal with.


There's no question that you can push your staff to work hard, something that not only has a benefit to the business if results are delivered, but also because it means that it will allow them to develop both professionally and personally.


Driving through a big project and delivering on time may mean going the extra mile at times, but the sense of achievement that comes with it is a feeling that is very hard to replicate and brings a lot of personal pride.


However, as a leader of a team or group you need to make sure that your you don't push your staff too hard. There is a very fine balancing act that needs to be undertaken here, as you need to discover where their breaking point is.


And it is one that really you don't want to reach as that could then have serious repercussions for your business further down the line, it only takes a workplace meltdown to occur for a whole host of momentum to be lost.


It's a similar scenario to one you would find at a casino, one that comes with weighing up risk versus reward. The risk is asking too much from your staff and facing a negative backlash, while the reward is delivering your objectives on time.


GIVE SOMETHING BACK

 

If a big project is in progress and there is a large amount of work that needs to be done, then another key aspect of being a good leader is being able to motivate your staff during what might see like tough times.


You should be prepared to give something back, especially in regard to time. If someone is constantly working late, then why not give them a half day as an act of gratitude to say that their work is not going unnoticed.


Or why not establish Friday drinks in the final hour of the week, not only does it release the pressure of a busy few days, but it will also allow you and your team to bond on a more social level. If your team all get on with each other then they will be prepared to go the extra mile when it matters. Maybe you could allow them to play mobile slots during their lunch break or maybe have a friendly office game of Texas Hold'em poker, which is both fun and stimulating.


As a leader you can also take the team out for lunch say once a month. Again, it not only offers a more sociable element, but it also gets your staff out of the confines of the office and mixes up their working day.


That's not to say that's all about team lunches and drinks, ultimately there is still work that needs to be done. At the same time though a lot could be said for the phrase "do the job and not the hours" and the benefits that come with a more flexible approach.


If work is done by 4:30 and your staff are due to finish at 6, then why not send them home to say thanks for a job well done. An act that will boost morale and keep you in your staff's good books, showing that you can be a good person as well as a good leader.
