Which UC Company Will You Choose? Communication is the lifeblood of any successful company. Without successful communication, you can’t provide the excellent customer service that your customers need or provide the collaboration opportunities that employees demand. With so many UC vendors to choose from, it can be challenging to determine which provider is right for you. Just remember that there’s no one-size-fits-all option. The UC solution you need will depend on your customers, your background, and your personal preferences.

6 Top Unified Communication Companies to Consider in 2019

In Javascript, you write some code and they get interpreted by the Javascript engine. To understand behind the scenes, you need to have an understanding of basics. To achieve that, in this article, we will be focusing on the difference between scope, context and execution context. In the road of understanding Javascript, difference between scope, context and execution context is crucial. Scope Since this article is a part of series, check out the rest of the series via the links at the end of article if you would like to learn more about the types of scope or how you can use it. Learn Javascript Fundamentals For a short explanation, scope is closely related to the . It is common to confuse scope and context, but in reality they are completely different. With scope, you control the . Variables created in global scope can be accessed from any scope whereas the local variables are accessible within the function in which they are created. visibility of variables accessibility of your variables Context Context is simply the value of the property of which will be explained later in this article “this”, execution context . It also refers to the object that function belongs to. Value of differs by how the function is called. In global scope, value of is always the object. “this” “this” window .log( ); console this // window If the function is a method, the value of is the object that method belongs to. Of course, keyword is not that simple to understand. In this article, I am not going into the details of how keyword work, just stressing out what its relation is to scope, context, execution context. Understanding how works is really one of the hardest and also most important topics in Javascript. There are, fortunately, lots of resources. If you are unfamiliar, I suggest that you check them out. “this” “this” “this” “this” 1. MDN Javascript.info 2. Mastering The Javascript 3. This Keyword Meaning of keyword depends on how and where the function is called, not where it is declared. Its meaning changes every time a function is called from different execution context. Why execution context? Because keyword is actually a reference to “this” “this” function’s current execution context. Execution Context Execution context is something that you need to know to understand how Javascript code runs. First of all, it is an that represents the in which Javascript runs. What happens inside the execution context is two things basically. First one is parsing the code line by line and the second one is storing the variables and functions into the memory. In simple terms, it has two types; abstract concept environment 1.Global Execution Context 2.Local Execution Context Global Execution Context is the first thing that is created when you write Javascript code. It is the default context. Local Execution Context, as you can imagine, is created when you call a function, not define. Because it is an abstract concept, I am going to support it with an image. Let’s walk through the image. When engine starts reading your code, it creates the global execution context, it starts parsing line by line and adds your variables to memory also known as global variable environment. Let’s say you have defined a function like this; { number=num+ ; number;
} ( ) function adding num let 2 return If you call adding function, adding( ); 3 While the engine is parsing, if it needs to execute the function, new local execution context is created. In that execution context, parsing takes place and variable is added to local memory, then parsing continues. After this, engine returns to the previous execution context. number Exiting the local execution context and continuing parsing in the previous execution context is achieved with keyword. Those arrows in the image represents this cycle. Every time a function gets called, this happens again. Every function call results in different local execution context. return To sum up briefly; 1.Global execution context is created first. 2.Whenever a function gets invoked, called or executed, new local execution context gets created. 3.Engine starts parsing the code in global execution context. 4.When engine comes across a function call, it enters a local execution context, continues parsing in there. 5.When it handles function execution, it exits from that local execution context, returns to previous one. This brings us to another important concept. How does engine know which execution context to enter or exit? The answer is . Call Stack Call Stack, in a simple term, is a mechanism for Javascript Engine to keep track of execution contexts, which to enter, which to exit or which to return. At the bottom, there is global execution context. If a function gets invoked, we have a new local execution context and this one is pushed to the top of call stack. Once it’s done, it gets popped out. Let me explain it with an image; So, what is going on here? 1.Engine starts parsing, global execution context is automatically pushed to the call stack. 2.Function1 gets invoked, local execution context is pushed to the top of global execution context. Engine will continue to parse after function1 is executed. 3.Inside function1, new execution context is created and gets pushed to the top of call stack. After function2 is executed, it gets popped out from call stack. 4.Function1 gets popped out after it is executed. 5.Finally, it returns to global execution context. Engine continues to parse and all of the code is executed. Phases of Execution Context Throughout the article, you may be wondering how the execution context is created. Despite being abstract, it is a process and the engine follows some steps in the process. Basically it has two phases; 1.Creation Phase 2.Execution Phase In the , engine first creates or . This object consists of variables, arguments, function declarations. In this stage, they are assigned the value of “undefined”. creation phase Activation object Variable Object Arguments property is also an object, array-like object, that has a length property and all arguments passed to the function call are stored in this object. After that, engine creates the scope chain. Each execution context knows its scope. It has a reference to its outer scopes all the way to the global scope and the engine searches variables, if exists or not, starting from the current to the global scope. And this is called scope chain. Scope chain is a list of objects consisting of its own variable object and its parents’ variable objects. Lastly, the value of ” is determined. In global context, its value is window/global object whereas in every function call its value may be different. “this In the , variables are assigned a value and the engine executes the code. execution phase If you would like to read more about Javascript Fundamentals, please take a look at the Learn Javascript Fundamentals Series. 1. Global Scope 2. Local Scope 3. Scope, Context, Execution Context Happy Coding!!!

As per the rule: Your deck should not exceed ten slides. The slides duration should not cover more than 20 minutes. It should be typed in less than 30-point font. If you want to hone your pitch, try not to bombard the slides with a lot of information. Instead, mention the laser focused points about your business, focusing on your core competencies in the same way. Now here are some of the critical components of a startup pitch decks that you should incorporate to achieve a better response of your investors. Problem The stories of the most successful ventures portray itself as a significant problem solvent that attracts more potential customers. They build a service that solves their problem like never before. It clearly gives an impression that you should highlight the "Problem - your product or service is solving" in one of the initial slides.  It is the perfect way to capture the attention of your investors. Paint your own business story by attractively representing your business idea. It will also help your investors to have a better understanding of your funding goals. Vision Another essential component of a pitch deck is to have a strong vision. Bring your business's primary goals/ missions on the board. Try to keep it concise and straightforward. A single-sentence overview could do wonders and adding some lucrative benefits & comparison with another well-known company is the icing on the cake. As an example, you could write, "We're like Facebook for Professors." By using such phrases, you can catch the attention and raise the interest of the investors to know more about your idea. Remember, do not overdo it, instead, write it in a way that it could reflect the ideology of a high profile name. Exclusive Value Proposition After describing your vision & mission of your startup, you should add Value Proposition in your pitch deck. The value proposition should represent the fact of how your startup venture is exclusively qualified to address the pain areas of your customers. Always try to highlight the following points: The uniqueness of your startup idea and give the reasons how it can stand out from the competition( business owners of similar niche). Mention how you are equipped with comprehensive solutions concerning all the possible issues. Give the fact of how your startup can achieve massive growth. Team I would like you to wonder what type of services provider you would choose if your valuable assets - time & money are at stake? Would you choose an experienced or non-experienced service provider? Undoubtedly, you would also prefer an experienced one. So, the same goes for your business venture. In your pitch deck, qualification of your team members should be a focal point. Your potential investors may build their faith based on all the experience & expertise your team members have. It helps them to understand that your team has enough potential to manage a high-growth startup. Milestones Before seeking financial investment,  you need to gain some early traction as a startup founder.

Moreover, it will explain how your business is going to make money. business structure You should leave a striking impression in the minds of your potential investors regarding your marketing strategy as well as the business model. It should be highly unique from others and must be capable of driving high profits. Competition Do you know which is the biggest mistake most startup founders make? Well, sometimes they think that they are hitting the ground without competition. However, every startup has some competitors(minimum one) that could beat them and steal their market space. So, add a slide regarding the same and mention where do your competitors stand out in the market? Highlight the mistakes they are making with a responsible solution that how your business model, products, or services are superior than them. While adding up this slide, make sure that content should be appropriate and must not pinpoint anything wrong or bad about the competitor's strategy. You need to give a comparative analysis. *Additional Tip: Ask It is also a very crucial section of your pitch deck. It outlines the fact where would you utilize the fund's investors will give you, and why it is vital for you to attain that amount.  You have to prepare for the further outgrowths of this slide like with plenty of expert insights and other essential data.

Top Tips to Create a Winning Pitch Deck For Your Startup 

Default EOS accounts EOS uses a different account structure than most cryptocurrencies you know. While it might seem complex at first, it is not that difficult once you understand the basics, all of which will be covered in this article. So, how do EOS accounts work? Account structure Every user has one or more accounts on the EOS blockchain. EOS accounts are human-readable identifiers that are stored on the blockchain and they are required to push or transfer any (valid) transaction to the EOS blockchain. These accounts can also be owned by multiple people depending on the permissions configuration. EOS accounts are 12 characters long and can contain the letters a-z and the digits 1–5. These account names replace the long and clumsy wallet addresses that are used in most cryptocurrencies. Furthermore, every EOS account has permissions. Permissions can be seen as requirements which need to be fulfilled in order for a transaction to go through. An EOS account has 2 native permissions by default: : shows ownership of the account and is needed to make any changes to the ownership the account. This key(s) for this permission is/are best kept (safely) offline, as they are not needed to do most things on the EOS network. Owner : used for transferring funds, voting for producers and making other high-level account changes. Active Besides these 2 native permissions you can create new, custom, permissions that fit your needs. Each permission has one or multiple keys and/or account name(s) associated with it. Each key or account name associated with a permission has a certain , and each permission has a certain weight which needs to be met before a transaction requiring that permission is accepted. weight threshold Visualization of a default permissions structure. (Source: EOSIO Developer Portal ) To help you understand all of this information we have included the above image, which visualizes the permissions structure of a default EOS account. As you can see, the permission has a default of 1, and 1 key with a of 1 associated with it. The same goes for the permission which has a default of 1, and 1 key with a of 1 associated with it. owner threshold weight active threshold weight This means that only the (private) key associated with the or permission is required to perform any transaction requiring the or permission. owner active owner active Account resources Now you are familiar with the structure of an EOS account, it’s time to learn about account resources. Each EOS account has 3 resources: , and , which all allow users to do different things. We will explain each resource individually below using a . CPU network RAM metaphor by EOS Asia How resources in an EOS account (can) look If the EOS blockchain was a train, CPU, network and RAM could be explained in the following way: Network would be the available seats in each train leaving and entering the blockchain. Your chair will always be reserved, and if u need it, it will be yours. BUT, if no one is on the train, you could lay across a bunch of chairs because they are free! So network is a way to make sure you have somewhere to sit when the train leaves. CPU is how often you can ride the train, and works much like network as far as allocation goes. You may have a train ticket, but of course the ticket is only usable on certain days and times. Now the EOS train is pretty laid back, so any unused space is free to use re: CPU and network, are free to use the people that paid for the space need to use the space. CPU and network are joint resources that together are called BANDWITH. RAM is your storage space on the train. If you need to bring a ton of luggage, you need to pay per bag to check your bags onto the train. If you do not need to bring a lot of luggage, you can sell your storage space to others that are riding on the train. and can be obtained by staking EOS, which is essentially locking your tokens for a certain time. When the user wants to move their EOS they can unstake their tokens, essentially making transactions free. can not be obtained through staking but can instead be bought and sold and is used to hold other tokens for example. CPU network RAM Putting it all together You now understand both the structure and the resources of EOS accounts, so it’s time to put all of this together in order to fully understand EOS accounts. EOS accounts and permissions visualized. (Source: Blockgenic ) In the above image you can see how the account structure is related to the account resources. The light blue lines indicate & are needed to perform any action requiring that permission. The red line indicates is needed to hold other tokens. This should give you a solid understanding of how an EOS account operates. CPU NET RAM Multisignature accounts Using the permissions structure within EOS you can do many interesting things. One of those things is creating a multisignature account, which is relatively easy on the EOS network. In general, a multisignature account (more commonly known on other blockchains as a multisignature wallet) is an account that requires more than 1 signature in order to perform a transaction. EOS accounts are more complicated, as they have multiple permissions with multiple actions associated with that permission, instead of a single possible action which is the case on most current blockchains. As a result of this more complicated account system it is possible to change the earlier described of a permission that needs to be met before any transaction requiring that permission can be executed. It is also possible to then add multiple keys with different to the permission. threshold weights Using these principles you can then require multiple keys to sign a transaction before it (and the action that the transaction performs) executes, essentially making your permission a multisignature permission!

Decentralized Cloud Storage is changing the face of the internet (2/2)

(Read Part 2 here ) That one single innovation since the last century, which probably has the most significant impact on our lives today is the internet. It started as a decentralized ecosystem back in the early days. The open protocols like TCP/IP and SMTP helped build different kinds of applications on top of the internet like the World Wide Web, emailing services, and messaging. However, the internet, s we know it today is all centralized, and companies are investing heavily in huge server farms that hold all our data and information. Too much ‘centralization’ is slowly killing the online ecosystem Centralization has its own unique benefits, which include: Higher speeds Low latency Higher availability Quick throughput But all these benefits come at the cost of severe drawbacks like data hacks and security breaches, censorships, and lack of control over your data, to name a few. If you carefully observe, the internet is dominated by a few technology companies, the ‘Big Tech’. In fact, the internet is dominated by only a handful of ten big companies, according to a blog post published by . Too much centralization also means that the governments can ban your access to any application, leaving you with no other options whatsoever. Mashable Hacks, censorships, and blockage are widespread in the centralized system One recent example came from Turkey where the government banned Wikipedia in 2017, claiming it was a ‘threat to their national security’. China has blocked access to popular social media, search engine platforms, and replace them with applications that come with lots of government surveillance, content blockage, and censorship. So now the question arises, how can we make the internet decentralized again with no censorship and more public control? Well, it is certainly possible as more and more advancements have been made into the ‘decentralized cloud storage’ space, which we will discuss more in this article. What is Decentralization, and how does it apply to cloud storage? Decentralization, in terms of technology, means that the system doesn’t rely on a central authority, it doesn’t have a single point of failure. In more technical terms, decentralization is a subset of distributed architecture where the decision making is performed independently by all the participating nodes, instead of relying on a single node. Decentralization has been around for many years, and it has more to do with governance, decision making, and control. The earliest example of a decentralized system is the internet itself, where the websites were hosted on individual PCs, followed by Napster and BitTorrent, which laid the foundation for peer-to-peer (p2p) file sharing. BitTorrent protocol became the most famous and widely adopted and is still used today in a variety of different applications. When we talk about cloud storage, ‘decentralized cloud storage’ means that you can store your data, not on one single server or location, but many different nodes spread across multiple locations. These nodes are independent of each other in terms of complete authority over decision making. It is quite similar to BitTorrent protocol where the users host files on their local storage and act as ‘seeders’ (sharing chunks of files with other users who want to retrieve them), but there are some fundamental differences. Decentralized cloud storage is made possible by the new protocol for the distributed web named IPFS (InterPlanetary File System). In the next part, we will dive a little deeper into the IPFS protocol. We will also discuss how it differentiates from the BitTorrent protocol, which is also built for distributed peer-to-peer (p2p) file-sharing over the internet. IPFS and how it builds the foundation for the decentralized cloud storage IPFS (InterPlanetary File System) is a protocol developed by Protocol Labs for the distributed web of the future. It aims to challenge the traditional HTTP protocol by building a more distributed and decentralized network. Both HTTP and IPFS are hypermedia protocols built for the web, to transfer any data between client and server over the internet. However, there are subtle differences between the two, in fact, IPFS aims to replace HTTPS to become the default protocol of the internet. Instead of a single server, IPFS works on a huge swarm of nodes that store different blocks of data and users accessing the network can retrieve this data from the nearest node. Below is the brief explanation of what happens to the files on the IPFS network: The file is divided into chunks of data called blocks. Each block is given a unique hash. IPFS works on deduplication, which means that all the redundant files are removed from the network. Every node participating in the IPFS network stores the content with its hash and some indexing information. When a user wants to retrieve the file, he is telling the network to find a list of nodes that have the content behind a particular hash. With IPNS, a decentralized naming system, each file can be easily found by human-readable names. One other significant difference between IPFS and HTTP is how they address the content over the internet. HTTP primarily uses something called ‘location-based addressing’ where you retrieve the content by addressing its location, which is the IP address of the server hosting that piece of content. On the other hand, IPFS uses something called ‘content-based addressing’ where you retrieve the content by either its name or a unique hash since the IPFS has deduplication all across the network, which means that every node is hosting exclusive content that makes ‘content-based addressing’ more efficient and reliable than the traditional location-based addressing. How the IPFS differentiates itself from the BitTorrent protocol? The IPFS sounds very similar to the BitTorrent protocol as both of them are distributed. However, they both are fundamentally very different from each other in so many ways. Let’s discuss a few key differences between the IPFS and BitTorrent protocol. IPFS is built for the web aiming to replace HTTP while BitTorrent is only built for peer-to-peer (p2p) file sharing. IPFS has deduplication all across the network, which saves a ton of bandwidth and resources. However, BitTorrent doesn’t have any deduplication, which means that there is a very heavy redundancy all across the network. IPFS uses ‘content-based addressing’ to retrieve the files while BitTorrent uses Trackers to locate the peers, which use ‘location-based addressing’ just like regular DNS and HTTP. All the data on IPFS is ‘immutable’, just like Blockchain, and it has a versioning system built in which keeps track of different versions of the same file. BitTorrent protocol doesn’t have this immutability and versioning system. IPFS has the capability of being an offline-first network that can significantly help in natural disasters or developing the world. BitTorrent doesn’t have any offline dressing mechanism built-in. With the hashing, content-based addressing and immutability, IPFS is ‘blockchain ready’. In fact, many blockchain platforms are using IPFS for distributed file storage already. BitTorrent, on the other hand, is best suited for peer-to-peer (p2p) file-sharing over the traditional internet model. What about privacy? Is decentralized cloud storage secure? Blockchains are immutable for sure. Decentralized file storage puts another threat on the table: privacy, security, and integrity of data. Fortunately, it has been taken into strong considerations, and different blockchain platforms take care of it in their unique ways. The majority of the applications that we will discuss in this article have end-to-end encryption and sharding. Before the distribution of files into the decentralized world, it is divided into blocks, and those blocks are encrypted and then distributed among many different nodes. For the file retrieval, you need to have your private key to decrypt the files. However, this is just a broader perspective of how secure decentralize cloud storage is. With no central location of your files and with encryption built into the system, decentralized cloud storage might be more secure than the centralize solutions available today. When it comes to IPFS, there is a problem — Why would the users utilize their local storage to store chunks of data for the IPFS network? How are they incentivized? In the , we will discuss different decentralized cloud storage solutions, which most of them are using blockchain on top. next section https://hackernoon.com/decentralized-cloud-storage-how-it-will-change-the-face-of-the-internet-22-np1f2349h

🤓 What is Codetalks? As programmers, we know how important it is to be up to date in terms of programming languages, frameworks, methodologies and tools in general. We must always be in continuous learning. One of the best ways to stay up-to-date is by attending technology conferences and events, but many of these events are not in our city or we simply cannot attend. The positive part is that most of these events are recorded and are available for free through different video platforms (mainly Youtube or Vimeo), which is great, but there are a couple of problems: ❌ There are plenty of interesting events and talks around the world every week and it’s hard to be aware that they exist. ❌ Each event is on a different date and is published on different accounts and video platforms, which makes it very complicated to track the events that interest us. That’s why we decided to create , a . Each video is grouped by tags and event so that it is incredibly easy to discover conferences, watch lectures and keep learning. Codetalks.tv platform for developers that brings together the best programming talks around the world in one place 📋 What should our MVP have? Considering that this is a MVP (minimum viable product) we wouldn’t want to extend the development time too much, therefore, we tried to identify the key functionalities that would give meaning to the project, in this way we could validate if our idea made sense or not before continuing to invest more time and effort in it. The characteristics we identified as most important were: Talks finder View talks by tag View talks by event View available tags View existing events Send talks (Youtube & Vimeo) Subscribe to a specific tag Receive feedback and ideas As for the design, it had to be simple and intuitive. It didn’t make sense to create anything new and extravagant and that’s why we opted for a design similar to that of Youtube, so that anyone can instantly feel familiar with it. Focusing more on the look and feel, we decided to make a small wink to our potential users, the developers, for this reason we gave it the appearance of a code editor (VS Code?), and even… we used the famous Monokai color palette. 🛠 Let’s get to work And it’s time to code! One of the interesting things about a side-project is that you can afford to experiment and try new things out, so, we didn’t want to miss this opportunity. Here is a brief summary of the technology stack we used, both for the backend and for the frontend. If you find it interesting, we will publish more articles explaining part of the development process in more detail. Frontend: : Create React apps with no build configuration Create React App : The perfect partner for GraphQL. The client is designed to help you quickly build a UI that fetches data with GraphQL. Apollo : A very popular CSS-in-JS styling library that uses tagged template literals in JavaScript and the awesome power of CSS to provide a platform that allows you to write actual CSS code to style your components. Styled-Components Other libraries or tools that have helped us a lot: : Open source tool for developing and organize UI components Storybook : This library is gold. It allows us to embed videos from YouTube or Vimeo, and customize them completely: Put our logo, remove the buttons from the original platform … etc.. Plyr : To create forms in a simple way (Everybody hates forms, right?). It is very useful used together with , an input validation library. Formik Yup : This is another simple library to perform small operations with colors. Color Backend: : Fully-featured GraphQL Server based in Express GraphQL-Yoga : Prisma is a database abstraction layer that turns your databases into GraphQL APIs with CRUD operations and realtime capabilities Prisma Third party tools: : This is the tool we use to receive errors that occur both in frontend and backend. In this way we can eliminate the small bugs that arise. Sentry : This is how users can subscribe to receive the latest videos from a tag, when they do so their email account is added to a Mailchimp list and from there we can then send the weekly summary of the best videos. Mailchimp : we use Cyfe to have in one place information from different parts of the platform. For example, we have a panel for Analytics, and another to see the number of users and videos we have on the platform. We can continue to add data and internal information from the platform to have it all in one place. Cyfe : we use Typeform to receive feedback from users because it is a simple and quick way to implement it and have it integrated with Slack to receive information instantly. Typeform And then came the moment of truth… 🚀 The launch The truth is that if we are taken out of the technical or product part we will feel like a fish out of water, one could say that marketing is not our strong point. That’s why, to define our launch strategy, we simply asked ourselves a question: Where are our potential users?, and based on the answers we found, we drew up a list of possible acquisition channels: ☠ Big portals (Disaster): We tried to follow all the advice we read by different blogs regarding a successful launch in PH, we knew it was very important and one of the keys to the launch, however we only got (very sad). Product Hunt: 9 upvotes We only got . Hacker News: 4 points We sent it to the subreddit g. It wasn’t published either. Reddit: r/programmin At this point, and after a truly horrible initial release, we wondered if actually made sense, are we really solving a problem and bringing something to the community? our motivation crashed. CodeTalks However, after a few days of decline, we decided to continue trying in other ways and this time, fortunately, it was better: ✌ ️Niche media (Not bad): We have appeared in several important blogs in the sector, which has brought us a very qualified traffic. Blogs for devs: We have been quoted in several newsletters, many of them with tens or hundreds of thousands of subscribers. Devs Newsletters: Since the beginning it has been a great ally, we get a lot of traffic through this social network, partly due to a very cool bot we have developed that posts talks and mentions speakers all day long (this is for another post). Twitter: Despite not having had a spectacular launch, we have seen over the last month how traffic has been increasing day after day steadily. In addition, we have received a lot of positive feedback, so the general feeling is that people like it, and although we think we have not reached product-market-fit yet, we do believe that we are going in the right direction and that it is worth continuing to invest some more time. In addition, we have a few very cool ideas for version 2.0, and…. why not, we’ll make another release later with lessons learned, maybe this time we’ll be luckier hehehe. 🎓 What we learnt If we had to draw some key lessons, these would be: Attempt to , a pain that you have detected in your own flesh. In this way you will be your own target client and you will know what you need. resolve a real problem . Don’t go crazy with the technology stack or the features that the MVP should have. Try to launch quickly and validate your idea as soon as possible. Keep things simple Since you’re doing a side-project, along the way. If the project finally fails, you will at least take with you new knowledge and something interesting to add to your portfolio. try to learn something new Don’t be discouraged if your project doesn’t receive all the attention you expected at the beginning, it could be for different reasons. . Be patient and try to improve your product little by little. Listen to your audience . Consider each new feature you add to the product as a new opportunity to make a new launch and get attention. Make lots of launches
