    What is AI pattern recognition?


    Pattern recognition is based on human behavior and is a feature of many of today’s widespread AIs. It has a lot to do with machine learning and algorithms, but let’s take a look at the details.

    What is AI in the first place?

    AI (artificial intelligence) is an artificial reproduction of the intellectual behavior of human beings using software. Computers acquire the ability to recognize patterns contained in large amounts of data, learn new patterns, and perform all tasks.

    Relationship between AI and machine learning

    Machine learning is one of the ways to analyze data to realize AI. The machine automatically learns the rules and patterns behind the data. In recent years, machine learning has placed the highest priority on prediction accuracy, and deep learning has become a typical analytical method. The characteristics of machine learning that learns and recognizes are the same as pattern recognition. In other words, pattern recognition is realized by utilizing machine learning.

    What is pattern recognition?

    Pattern recognition is the process of identifying and retrieving certain features and rules from data. The features and rules here are not logical information but are found from images and sounds, so they are generally supervised learning.

    Even if we humans are not familiar with the word pattern recognition, we usually perform the same intellectual behavior. For example, when searching for a friend from many people at a meeting place, it is based on the characteristics (height, face, voice, etc.) of the friend, and this behavior corresponds to pattern recognition.

     

    Process flow by AI pattern recognition

    What is the flow of AI learning pattern recognition? From here, let’s deepen our understanding of the processing flow in pattern recognition.

    Pre-process

    First, in order to make it easier to extract features, we mainly perform processing such as digitizing the data signal and removing noise. If there is a problem with the data, it will not be possible to extract the appropriate data, so it cannot be used as it is. Pretreatment enables efficient feature extraction, which is the next process. In addition, equalize the variance of each scale.

    Extract features

    After the pre-processing is complete, the essential characteristics of the data are extracted in order to make a judgment based on the data. Depending on what you recognize, you need to clarify the features to be extracted. Features are expressed numerically, and the features that are picked up and arranged are called a feature vector.

    Identify / classify

    It identifies which class the feature vector existing in the feature space corresponds to, and classifies it by class. Machine learning is used because this identification / classification work has very high-dimensional features and is extremely difficult for humans to perform manually.

     

    AI pattern recognition algorithm

    There are many algorithms that show the calculation procedure for AI to perform pattern recognition. It is necessary to properly use the algorithm depending on the purpose of pattern recognition. From here, we will explain each algorithm.

    Neural network

    A neural network is a mathematical model of neurons, which are the human cranial nerve system. By enlarging and complicating this neural network, high performance is demonstrated in various tasks.

    Naive Bayes

    Naive Bayes is a model for solving classification problems. It is based on “Bayes’ theorem” which is the theorem of probability theory. The amount of calculation is small, the processing is fast, and it can handle large-scale data.

    Logistic regression

    A model for solving classification problems. When an input is given, it outputs which class the input is classified into and how likely it is to be classified. For example, in the two-class classification, the probability that a certain event will occur is predicted, and if the probability is greater than 50%, it is classified into the class of “a certain event will occur”, and if not, “a certain event will not occur”. Classify into classes.

    Random forest

    It is an algorithm that predicts each class in multiple different classification trees and decides which class to classify by majority vote. It is easy to handle because there are few parameters that must be determined in advance.

    k-nearest neighbor method

    It is a classification method that is frequently used in pattern recognition and is based on the closest training example in the feature space. It is a method of supervised learning of problems for which the answer is already known.

    Support Vector Machine (SVM)

    An algorithm that can be used for both classification and regression, it is an algorithm that uses supervised learning to find a linear function (hyperplane) that separates two classes on a feature space. A support vector is a data point that is closest to the data dividing line. It has the advantage of being easy to separate correctly even with a small amount of data.

     

    What you can do with AI pattern recognition


    The number of patterns that AI can recognize is innumerable, just like the patterns that humans can identify, and the number of pattern recognition is also very large. Among them, the following three are said to be characteristic. Let’s take a closer look at the technologies that are possible with each recognition.

    Recognize images

    Image recognition is a technique in which a computer determines what is in the target image. With the development of deep learning, it is used in a wide range of fields. The first popular technique for image recognition was barcodes in the 1940s. After that, a method of comparing the similarity of the target images appeared, but it was a difficult situation to put into practical use because of the great disadvantages. In the 2000s, as the accuracy of machine learning increased, pattern recognition using a large amount of image data became mainstream. Face recognition is a typical technique in image recognition. The number of scenes that are applied to face recognition when entering offices and large-scale event venues is increasing rapidly.

    Recognize characters

    Character recognition is widely known by OCR (Optical Character Recognition). It is a technology that reads handwritten characters and images with a scanner or digital camera, extracts them, and then converts them into digital character codes so that they can be used on a computer. In Japan, full-scale use began when Toshiba first commercialized domestic OCR in 1968. Currently, there are many companies that are promoting operational efficiency by introducing OCR, regardless of the size of the company.

    The flow of utilizing OCR is to first capture the image of the manuscript for which character recognition is desired, and then perform layout analysis to determine the character part from the image. After that, the line is cut out line by line, the characters are further decomposed for each character, the characters are cut out, the characters are recognized, and then the output is performed in the format. In these steps, normalization to make characters a certain size, feature extraction to process characters so that they can be recognized accurately, standard patterns to register all the characters you want to recognize, etc. are performed.

    Recognize voice

    A technology that uses a computer to convert voice data into text data. With the spread of voice recognition services and smart speakers, the usage of voice recognition technology continues to expand. Speech recognition needs to go through four steps. By acoustic analysis, we perform an acoustic model that converts the data into data that is easy for the computer to recognize and calculates the success rate with the learning pattern. Next, the language model creates more accurate sentences, and the pronunciation dictionary words the combinations of sounds. By utilizing deep learning, it became possible to implement the process from the acoustic model to the language model in one, which led to a significant improvement in functionality.

    • Multi-signature wallets, or “multiseg wallets” for short, are a type of cryptocruncy wallet that require at least two private keys to sign transactions.

     

    • Imagine a safe locker with two locks and two keys held by two parties and can only be opened if both parties use their keys to do so.

     

    • In the Bitcoin Lightning network, opening a payment channel between two parties requires a multi-signature transaction, where each partner locks a certain amount of bitcoins in a multi-sig wallet and then sends each partner two One of the required keys is received.
    In this tutorial, you will learn more about multiseg wallets and why they are used.

     

    What are Multiseg Wallets?

    How do I create a multiseg wallet?

    A crypto wallet is a digital or analog storage solution that a crypto holder needs to access their cryptocurrencies. Basically, a crypto wallet mechanic (with a signature) has two essential elements.
    The first is a public key (” Public Key “), which can be compared to an account number. The hashed version of the public key is the owner’s wallet address. To access and control the funds, the user needs a private key, which is similar to the PIN code of that bank account. Therefore, it is extremely important that only the crypto-holder can have the private key to ensure that only he/she has access and therefore full control over the crypto-holdings associated with that address.

    What are the risks of single signature crypto wallets?

    Always remember that the security of your crypto wallet should be a top priority, with cold wallets being the safest way to store your crypto holdings offline, keeping your crypto inaccessible to third parties.
    However, with all traditional crypto wallets with a single signature, there is still the theoretical risk that someone can steal private data from your computer (considered a “hot wallet”) or even from your cold wallet (offline storage). Can steal the key. And can possibly appropriate your cryptocurrencies.
    You can think of a traditional crypto wallet as a “single-sig wallet” with only one private key, or a wallet where only one signature is required to authorize a transaction.

    What are Multiseg Wallets?

    You can think of a traditional crypto wallet as a “single-sig wallet” with only one private key, or a wallet where only one signature is required to authorize a transaction. Multisig wallets, on the other hand, require at least two private keys to sign transactions, making them more secure than single-signature wallets. But what does this mean in practice?
    First, multiseg wallets provide greater security not only to teams and organizations that need to manage shared assets and transact with multiple parties, but also to individual crypto holders: a crypto user has There may also be multiple private keys (“signatures”). wallet, which means the risk of accessing one’s crypto holdings is further reduced when multiple signatures are required, as some multi-sig wallets offer private key integration from other wallets.
    And then, self-explanatory, multi-seg wallets are a very secure method to store crypto for groups or organizations that are spread across the globe and want to manage funds in a trustless environment where the parties involved know each other. Don’t know personally.

    How can I create a multiseg wallet?

    In general, setting up a multi-sig wallet is no more complicated than creating a single-sig wallet. After selecting your co-signers or the number of people you want to share the wallet with, you add participants to the wallet with just a few clicks and also choose whether to make a transaction. How many signatures are required, which is equal to how many are private. The keys will be in your wallet. Of course, if you want to use a multiseg wallet alone, you can also use it as an additional layer of security.
    Multiseg wallets are a highly secure way to store crypto for groups or organizations spread across the globe that want to manage funds in a trustless environment where the parties involved don’t know each other personally.
    Also, all co-signers must have a password, called the “Master Public Key”, to access the shared multisig wallet. The difference between a master public key and a traditional public key is that to make a wallet truly “multiseg” you must share it with each of your co-signers. After the co-signers confirm that they want to “join”, the multisig wallet displays how many participants must sign to accept the transaction.

    What are the advantages and disadvantages of multiseg wallets?

    The advantages of multiseg wallets are obvious, besides being difficult to hack due to multiple private keys. Passwords are stored in multiple locations or on different devices, reducing dependency on a single device. Using a multisig wallet also reduces reliance on one party because co-signers can step in if something happens.
    At the same time, this is one of the disadvantages of multisig wallets. If all signatories collectively decide to commit fraudulent transactions, recovery of stolen funds can prove very difficult. Additionally, when a multiseg wallet is used by only two parties, there is always the risk that one party will block a transaction initiated by the other party if they disagree with it for some reason. For this reason, the “2 of 3” scheme is a safe option. In this case two parties transact, but a third party is also involved as an arbitrator who is solely responsible for resolving any dispute.
    In addition, transactions can take longer because so-called Threshold Signature Wallets (TSS) require multiple signatures during a transaction, starting with a single trusted party signature, then a private Divide the key among the number of participants. The signature appears on the blockchain as a standard single signature, having multiple signatures instead of one significantly increases the transaction size. For this reason, single sign transactions are given preferential treatment by miners and can result in processing delays, higher gas fees on the Ethereum blockchain, and higher transaction fees for multi-seg transactions.

    What are multisig wallets used for?

    Currently, multiseg wallets are used either as regular wallets with increased security or as elements of the Lightning network.
    Bitcoin’s Lightning Network is a Layer 2 scaling solution for the Bitcoin network. On the Lightning Network, participants can establish payment channels between two parties where an initial deposit is made, which can then be used to send transactions over the Lightning Network to a certain extent, with each The balance is updated with the transaction.
    Since these transactions are not stored on the blockchain, they increase the size of the network. Each transaction requires the consent of both parties, which is why Lightning wallets are also “multi-sig” and therefore each party has its own private key. Bitcoin users who regularly transfer small amounts of BTC benefit from near-instant transaction processing and low fees.

  • How blockchain will change the world by creating a machine of trust?

    How blockchain will change the world by creating a machine of trust?

    A blockchain is a machine that creates trust”, and emphasizes that “the extension of the meaning carried by the technological innovation of blockchain goes far beyond the cryptocurrency itself”.

    “Block A chain is a machine that creates trust” and emphasizes that “the extension of the meaning carried by the technological innovation of the blockchain goes far beyond the cryptocurrency itself.”

    To put it simply, blockchain enables people to cooperate with each other without trusting each other and without the endorsement of a neutral central authority. Therefore, we can indeed regard it as a machine that creates trust. But how does this “trust machine” change the world?

    The “trust issue” has always been a crucial issue that has plagued the coordinated development of human society. However, this problem was not without solutions in the past.

    For people or organizations that do not trust each other, if there is a need to cooperate, there are usually two modes in the past.

    One is that we use the reputation system to try to trust first. If there is no problem during this period, we will accumulate reputation and we will continue to cooperate next time; if there is a problem and we do not keep our promises, then there will be no next time. This kind of trust mechanism is indeed useful in unlimited games, but once the number of games is known, problems are likely to occur. For example, we often see news about “tourist attractions slaughtering customers”. The main reason for this is actually that locals know that most people may come this time in their lives.

    The other is to rely on a third party that everyone trusts, that is, the “guarantor model” or the “trusted third party model.” For example, A and B need to cooperate, but they do not trust each other, but A and B trust C, then C can act as a guarantor. If there is a transaction between A and B, if either party violates the contract, then C will pay. When we buy things on Taobao, Alipay actually plays the role of “C”. Or more directly, A and C trade directly, and C trades with B. At this time, C is called the central counterparty.

    How blockchain will change the world

    Compared with the former, the latter model does not have the problem of “non-infinite game failure”, but it is not perfect. Because in this model, everything depends on “C is reliable.” If C wants to run away or open a convenient door for himself, then the whole model will collapse.

    In our current real society, the ubiquitous and operating trust mechanism is mainly the latter “trusted third-party model.” Just like, we trust WeChat Pay, essentially trusting Tencent; we deposit money in the bank, essentially trusting the bank; we believe that the stocks we buy are really stocks because we trust the state-guaranteed exchange and the legal system.

    In short, the current operation of our entire society is filled with a large number of trust models of “trusted third parties”, relying on trusting individuals, companies, organizations, governments, and mutual restraints and guarantees, notarization, laws, and regulations between individuals. A series of explicit rules, unspoken rules, such as procedures, procedures, and the combination of these trust factors.

    Of course, this kind of trust mechanism is considered to be well-tested and works well so far. Although there may be various flaws and loopholes in the middle, they can all be improved through the improvement of the trust factor and iteratively upgraded. For example, certain types of contracts are prone to default, and the risk can be controlled by increasing the mortgage guarantee ratio.

    However, in addition to relying on third parties naturally, this trust model still has certain limitations and deficiencies in some broader issues.

    Such as currency. As we all know, a human currency currently follows the latter type of trusted third-party model and is essentially a central counterparty model, so it is inevitable that the central counterparty will break the trust. For example, the fiat currency issued by the central bank tends to depreciate in the long run and is always inflated. This is actually stealing everyone’s wealth, and countless A and B who trust C have suffered losses. . This is actually the concept of “seigniorage” that we often hear.

    Another example is the cooperation between some large companies, especially those involving information and data. Just like mobile phone manufacturers, they each have some blacklist information about harassing calls, but they basically do not share each other. But we know that the more complete this kind of data, the greater the value to customers. The problem is that it is difficult for everyone to find a suitable “trusted third party” to share information and data.

    There are many such problems. In short, the same is true between people, enterprises, and countries.

    Iis there a third model?

     

    How blockchain will change the world

    The original intention of this design is that no one can be trusted to play the role of “C”, and all transactions must be under everyone’s eyes. All in all, the goal of the design is to make everyone’s benefits of not cheating higher than the benefits of cheating, so as to encourage everyone not to cheat.

    Bitcoin is the verifier of this model. At least for now, this experiment is still successful.

    In short, blockchain technology provides a new solution model, without any artificial trust factors, a completely machine-based trust model. It replaces the role of a trusted intermediary with a machine and uses a set of mathematical algorithms to ensure that two parties who do not trust each other can still complete transactions or achieve cooperation without resorting to a third party. This also makes it possible to achieve broader social collaboration and even large-scale global production collaboration.

    Just like the issue of information and data sharing between mobile phone manufacturers mentioned earlier. Everyone can create a consortium chain and make all the use of information public to all parties, so that not only do you no longer have to worry about the leakage of third-party information, but you can also avoid intrigue with each other, so as to achieve win-win cooperation.

    In addition, the trust model created by the blockchain can greatly save costs compared to the traditional “trusted third party” model.

    The modern economy is built on multiple levels of trust. We trust technology giants, banks, insurance companies, governments, and many more institutions every day. But as everyone knows, the cost of trust in our society is extremely high. In the case of banks, in order to allow us to trust and deposit money with confidence, they spend trillions of system maintenance costs (backstage, front desk, and facade) every year. At the same time, banks can also make trillions of dollars in profits. . However, from the perspective of users, these are actual costs. In order to save and withdraw money with ease and peace of mind, we have to spend trillions of costs every year to support the banking system.

    How blockchain will change the world

    We trust so many institutions that we take it for granted that the economy is built on multiple levels of trust, and therefore often overlook the high costs behind these trusts.

    And because the blockchain can replace the role of trust intermediary with a fully mechanized trust model, it can also greatly reduce the credit cost of our entire society.

    All in all, the birth of blockchain technology has provided a more exciting solution to the long-standing trust problems and information asymmetry problems in our human society. In the future, as the application of blockchain technology penetrates into all walks of life, blockchain technology will greatly reduce the transaction costs of the entire society, improve efficiency, and create a better future for us.

  • How blockchain will change the world by creating a machine of trust?

    How blockchain will change the world by creating a machine of trust?

    A blockchain is a machine that creates trust”, and emphasizes that “the extension of the meaning carried by the technological innovation of blockchain goes far beyond the cryptocurrency itself”.

    “Block A chain is a machine that creates trust” and emphasizes that “the extension of the meaning carried by the technological innovation of the blockchain goes far beyond the cryptocurrency itself.”

    To put it simply, blockchain enables people to cooperate with each other without trusting each other and without the endorsement of a neutral central authority. Therefore, we can indeed regard it as a machine that creates trust. But how does this “trust machine” change the world?

    The “trust issue” has always been a crucial issue that has plagued the coordinated development of human society. However, this problem was not without solutions in the past.

    For people or organizations that do not trust each other, if there is a need to cooperate, there are usually two modes in the past.

  • What is FileMaker? Easy-to-understand explanation of basic knowledge and what you can do

    What is FileMaker? Easy-to-understand explanation of basic knowledge and what you can do

    Companies need “database management software” to manage huge amounts of data.
    Among the many management software, do you know “FileMaker” provided by Apple’s subsidiary Claris International Inc., which is easy to operate without IT expertise?
    This time, I will explain the basic knowledge of FileMaker and how to install it in an easy-to-understand manner.

     

     

     

    What are a database and low code?

    In the first place, a database is a “collection of collected data”. The tools and software that manage this collected data are called database management systems. In the modern IT society, the amount of information handled by companies such as customer information, order history, and employee lists tends to be enormous, and it is difficult to manage without creating a database of information.

    If you use database management software, you can easily extract detailed data such as “I want to extract only customers in Tokyo from the list” and “I want to check last year’s order history in order of sales”. To put it simply, it is a database that can manage multiple data at once, even for lists and lists created with “Excel”, which is familiar as spreadsheet software. To give an analog example, a paper telephone directory or a job information magazine can be said to be a database of telephone numbers and job information.

    In addition to being used in system and application development, this database may also be used to analyze collected data for sales strategy planning and marketing. There are many database management software that boasts a high share of the world, such as “Oracle database”, which has excellent extensibility, and “MySQL”, which is also used to build search engines.

    However, when dealing with such a database, in addition to learning the SQL language, VB.NET, HTML, PHP language, etc. necessary for designing the user’s operation screen (UI), as well as automatic processing (automatic processing ( You can run an application only after learning advanced programming languages ​​such as Java and C # for building scripts). Programming is also called coating because developers write code so that they can understand it on their computers. If the language used by professional developers is expressed as pro code, the tool for coding with almost no programming language, that is, mouse operation (drag and drop) or creating an application with general keyboard operation is a low code tool. A tool that completes an application without writing any code is a no-code tool.

    The low-code and no-code concepts help people in the field who are familiar with the field of business to create applications that contribute to their achievements. For example, at one airline, active pilots have created low-code applications for proper training and screening, and more than 2,000 pilots are working on safe operations using iPads. In addition, doctors have created a questionnaire app for their clinical department, and visitors can enter it on their iPads to achieve paperless operations.

     

    What is FileMaker?

    FM is a database management system developed by Claris International Inc., a subsidiary of Apple. Although it is software with a long history released in 1985, it is still being upgraded even in the present age of Reiwa, and it is used by more than 200,000 organizations in Japan, and its popularity can be seen. Similar to other systems, it can store and manage the collected data, but FM has the feature of being “easy to operate” among many systems and has a good reputation as the best database management system for beginners.

    FM is suitable for beginners because it requires “less expertise”. For example, even if you create an application form based on the data prepared in Excel and publish it to the outside for input from a mobile terminal, you can simply operate the mouse and keyboard without programming (coding). It is possible to complete it. This is called no-code development.

    You can also use FM functions and scripts to automatically display your address when you enter a zip code, automatically enter katakana when you enter Chinese characters, and automatically display your age from your date of birth with minimal coding. You can also do it. This is low code development.

    Furthermore, by using FM and development languages, such as linking with tools such as SNS, linking with programs such as AI (artificial intelligence) and machine learning, and linking with FM using JavaScript, which is the development language, Professional developers can also complete their apps faster.

    Many of the database management systems mentioned above, such as Oracle and MySQL, operate using a special language called the “database language” to operate system. In addition, developing applications using databases requires knowledge of programming languages ​​such as Java and PHP, as well as coding skills. To put it simply, you can’t run a database management system such as Oracle or MySQL without the expertise and skills.

    Even in a database management system that tends to give such a difficult impression, there is no need for a database language or programming language to operate FM. You can build a database or system with just intuitive mouse operation and Japanese input.

     

    What you can do with FileMaker

    Customer list
    Customer numberCompany NameaddressDepartment in charge
    001〇〇 Co., Ltd.Tokyo CitySystem Development Department
    002△△ transportationOsaka Prefecture △△ CitySystem Development Department
    003□□ ProductsKanagawa Prefecture □□ TownProduction department
    004XX Mfg. Co., Ltd.Akita Prefecture XX VillageProduction department

    FM falls into the category of “relational databases” within databases. This is a database management system that uses columns (columns) and rows (records) as shown in the figure, and has the feature that “it is easy to manage and extract the input data”. Since it is easy to add information after creating the database, it is suitable for developing business systems and mobile applications that are frequently updated and used daily.

    • “Personnel management system” that performs personnel evaluation and labor management
    • “Budget management system” that manages expenditures and expenses for each department
    • “Customer management system” that organizes business negotiations and company products together with customer information
    • “Inventory management system” to check inventory status and delivery status in real-time from outside

    In recent years, on-premises used in-house and systems in the cloud environment are increasingly coexisting, but FM is also useful in hybrid environments where both are used. Some people may wonder, “Is Excel enough?” If you simply create a database for management, but with Excel, the more management items and data volume, the more complicated the input and output of data. It will be easier. As a result, it tends to be a difficult database to handle, such as saving old and new files on a personal terminal and not being able to access them at the same time by multiple people.

    In that respect, FileMaker can set detailed processing methods such as “import conditions” and “output conditions” for data. You can also synchronize master data with various related apps in real-time. For example, if you change the employee information in the master, it can be automatically reflected in the personnel system, expense settlement, customer management system staff, inventory management system staff, etc., and can be managed collectively. In addition, if you set permissions, even when accessing from outside, a limited number of people can access only limited information, and there is no worry about data leakage. If it’s a simple database, Excel will suffice, but using FileMaker will make it easier to create a database that meets your detailed needs.

     

    Benefits of deploying FileMaker in your enterprise

    Databases and systems created with FileMaker can be shared by multiple people, so it’s not difficult to use the same database within a department or team. If a company that does not have an IT professional such as an engineer or a programmer realizes DX (digital transformation), we recommend FileMaker, which has excellent no-code and low-code development, free screen design, and high operability. increase.

    In addition, FileMaker is a database compatible with multiple devices that can be operated on Windows, Mac, web browsers, iPads, and iPhones. Even data saved in multiple file formats such as CSV and XML can be automatically imported by building a scheduler with FileMaker, making it an ideal database for companies seeking a seamless development environment. You can say that.

    In addition, FileMaker also has a function that can be linked with Web APIs such as “Google”, which is useful when you want to develop a management system using an external Web application that is difficult to realize with Excel. In addition, FileMaker provides templates for each database such as “employee information” and “invoice”, so you can easily create a database or system just by entering items. Another advantage of FileMaker that Excel does not have is that it is easy to reduce the man-hours and costs required for production.

     

    What are the disadvantages of FileMaker?

    Although FileMaker has a low technical threshold and a reputation for high operability, it often requires specialized knowledge and skills to make minor modifications to the completed database and system. Also, compared to other databases, FileMaker has the disadvantage of slow processing speed, such as when processing millions of records, so system development that requires responsiveness such as convenience store POS systems and bank ATMs. It is also unsuitable for building a website that is accessed by thousands of people at the same time.

    Low-code development tools for companies located in industries where the business environment is changing drastically, organizations that cannot decide the completed model at the development stage and proceed with agile development through repeated trial and error, and companies that require development speed. It is also a good idea to adopt FileMaker as a tool.

    With FileMaker, developers can accelerate and accelerate the development process that reflects user feedback. In the case of the United States, companies that are no longer busy with development can think about ways to solve their problems in a short period, spend time creating innovation, and even months. It seems that some companies develop with FileMaker and perform user tests before starting production development with Oracle etc., which requires a development period, and absorbs the feedback.

     

    Main types of FileMaker

    typeFeatures
    FileMaker ProBasic development and client system running on Windows / Mac
    FileMaker ServerDedicated server software for publishing FileMaker data
    FileMaker GoA system for operating FileMaker on iPad and iPhone
    FileMaker CloudFileMaker that can be operated on the Internet (cloud)
    FileMaker WebDirectAbility to run the created database on a web browser

    Another feature of FileMaker is that you can create one app and use it in various environments and devices. You don’t have to make them separately for Mac, Windows, iPhone, etc. App development is done in FileMaker Pro. If you want to use it on your iPad, use Filemaker Go, which is free to download, and if you want to share it with multiple people, use Filemaker Cloud or Filemaker Server. If you want to operate with a web browser or Android device, use WebDirect.

     

    How to deploy FileMaker in-house

    FileMaker can download the system from the official website, but you need to register your name, phone number, email address, etc. from the input form. When deploying FileMaker in a company, enter the company name (or organization name) and the number of employees. Claris, which releases FileMaker, is an American company, but you can input Japanese on the official website, so you will not have any trouble getting the system.

      How to purchase Claris FileMaker

    You can use FileMaker for free for 45 days, so it’s a good idea to consider a full-scale introduction after trying out the usability. If you want to continue using it after the free period, you will have to select the above plan before making a contract. Make sure to choose a plan according to the size of the company and the number of people. By the way, if you install FileMaker individually, you will purchase the usage right in the form of a single license, but since the fee changes depending on the purchase or upgrade, please check the official website of FileMaker for details. ..

    It’s undeniable that FileMaker has a minor image when compared to well-known databases such as Oracle and MySQL. However, FileMaker continues to be upgraded even in the modern age of Reiwa, and features have been added and refurbished. Nowadays, the image of “database for beginners” is being dispelled, and many companies are adopting FileMaker as a development environment because of its excellent operability.

    There are many low-code development tools out there, but if you don’t choose the right low-code platform for yourself, it can be more costly. There are many tools with simple functions and low prices, but there is a possibility that the necessary functions will be insufficient during development and it will hinder the execution of the project and the realization of DX that should be the original purpose only for digitization. , It may not be possible to pursue efficiency. If so, choose a platform that continues to evolve in functionality.

  • How can I avoid ICO scams?

    How can I avoid ICO scams?

    In this lesson you will learn how to recognize potential scams in the cryptocurrency sector and what you should look out for.
    The methods of raising funds for new coins are as revolutionary as the blockchain technology itself. ICOs (Initial Coin Offerings) are a breath of fresh air in the fundraising world and may even replace traditional venture capital financing for startups over time.
    However, it also has a few disadvantages. Investing in ICOs is risky. Scams are common and sometimes suspicious schemes are very difficult to spot at first glance.
    Caution: To ensure that you only invest in worthwhile projects, you should be aware of some warning signs that indicate that a project requires a lot of caution.
    Before investing in a project, be sure to ask yourself the following questions:

    Do I understand this plan?

    Does the project have a real “use case” and can I understand it? What is this plan for? Or are only keywords like AI, blockchain, decentralized, revolutionary, etc. used? If a project’s white paper doesn’t make it clear what the project’s goal is and you read on and find yourself more confused than ever, caution is advised. If a project doesn’t make sense to you, you shouldn’t invest in it.

    Can this project have real benefits?

    Can this project be profitable? If not, it will get little attention because people only buy things they value.
    If something looks suspicious to you, it probably is.
    After browsing the website, watching videos about the project and reading the white paper, but still not sure what the project is trying to achieve, you should try the infamous duck test: “If it looks like a duck, swims like a duck and quacks like a duck, then it’s probably a duck.

    Does the ICO project really need blockchain?

    Does this project really need blockchain technology to function or will it work without blockchain? The white paper should clearly explain why blockchain is needed within the project and what role it plays in future product development. You should really only invest in projects that are revolutionary and offer a unique service right after their token ICO.

    Who is behind this project?

    Of course, every now and then, people who appear out of nowhere and have no track record in the industry have brilliant ideas and are busy launching the next big thing on the scale of Google. Unfortunately, however, you’re far more likely to be scammed by actors you didn’t even know existed than by reputable crypto entrepreneurs and developers.
    Ideally, the founders are business oriented and already successful in the industry. For example, they have won awards, they run well-known and established companies, their photos and bios appear in the team section of the website, etc.
    The only exception to this caveat regarding anonymous actors is the Bitcoin Project, created by Satoshi Nakamoto, who still maintains a pseudonym.

    Do your own research.

    If you are interested in a project, you should show your initiative and find out as much detail as possible. Read white papers and posts on social media like Medium, Telegram and Discord, interact with others and find out everything you want to know. However, never base your decisions on someone’s internet posts, such as forums.

    Do a project’s “bad times” show up in the roadmap?

    Every serious project should present a clearly structured plan that is always up-to-date and includes all project phases, old and new goals and milestones. If the project plan is incomplete or unstructured, something is wrong. Remember: No matter what project you are interested in, if there is no roadmap available, you should reconsider your investment. Don’t forget to do your research.

    Can you chat with the founders?

    We can all imagine how busy the schedule of project initiators must be. Those who approach a project with passion still make sure to allow enough time to interact with their community and not disrupt the flow of information. It is ideal if the founders of a project are reached through Telegram or other social channels and regularly informed about the project.
    It shows professionalism when project managers keep their community informed about the current status of the project and any changes. This means that they value the opinion of their community. If project managers are keeping a low profile or are unwilling to comment, there may be a reason.
    • Attention: If a project meets all the requirements, it is not guaranteed to succeed.
    People who do not make hasty investment decisions and invest carefully will learn to recognize how an ICO was created for purely fraudulent purposes. If you spot a scam early, you can invest in an ICO instead, which will pay you back in both time and money.

  • Can cryptocurrencies like Bitcoin be hacked or blocked?

    Can cryptocurrencies like Bitcoin be hacked or blocked?

    Bitcoin is considered hack-proof because the Bitcoin blockchain is constantly verified by the entire network. Therefore, threads on the blockchain itself are very unlikely.

    • Since blockchain technology is centralized and distributed, hacker attacks can be safely prevented.
    • A 51% attack can unbalance the blockchain.
    • Bitcoin has never been hacked until now.
    • Wallets used to store cryptocurrencies are easier to hack than blockchains.
    • Accordingly, there are always successful hacker attacks on people and websites.
    Why Bitcoin Can Be Considered “Hack Proof”?
    What happens if a hacker attacks the Bitcoin blockchain?
    What is a 51% attack?
    Can Bitcoin be locked/unlocked?
    Why are bitcoins stolen?

    Why Bitcoin Can Be Considered “Hack Proof”?

    Bitcoin is considered hack-proof because the Bitcoin blockchain is constantly verified by the entire network. Therefore, attacks on the blockchain itself are very unlikely. To add a new block with bundled transactions, each participant (miner) solves complex mathematical problems by constantly updating the Bitcoin database.
    These complex mathematical problems arise from Bitcoin’s cryptographic hash function. When a particular block is added to the database, every node in the network must agree on the block’s validity. Only when all nodes match will the Bitcoin database be updated accordingly.
    Manipulation of the cryptocurrency network is almost impossible. Decentralized, temporal, computational and powerful Bitcoin blockchain not only prevents deletion and overwriting of pre-validated Bitcoin block, but also prevents double spending.

    What happens if a hacker attacks the Bitcoin blockchain?

    As you already know, there is not just one copy of the Bitcoin blockchain. Instead, every node in the Bitcoin network has a copy. Nodes are distributed worldwide and contain all Bitcoin transactions made to date.
    A hacker who wants to change the distributed database of Bitcoin or any other network based on blockchain technology will have to hack not one, but more than half of the computers participating in the network (51% of the attack).

    What is a 51% attack?

    A 51% attack is the biggest threat to the blockchain if such an attack is successfully carried out by a person or organization and thus captures most of the network’s mining power (hashrate) and compromises Bitcoin’s transaction history. can go. The network can be changed and overwritten purely theoretically.
    A majority (i.e. 51%) is always required to decide which transactions are accepted and which are rejected. This means that a majority of 51% can change the blockchain’s distributed database. This will cost twice as much – it is possible to spend the same transaction multiple times. However, it is very rare that such a scenario will actually occur.
    A 51% attack on Bitcoin has never succeeded, and the network has never shut down, even for a brief moment.

    Can Bitcoin be locked/unlocked?

    A 51% attack on Bitcoin has never succeeded, and the network has never shut down, even for a brief moment. Additionally, several authorities and banks have repeatedly called for the shutdown of the Bitcoin network. Every time without success, because Bitcoin has been running without interruption for almost 10 years.
    For a complete system failure of the Bitcoin network, many things would have to go wrong. Here are a few “doomsday scenarios”:
    If there was a worldwide power outage, the Internet and all communication channels were shut down, the nodes in the network would not be able to communicate with each other and the entire Bitcoin network would shut down.
    The Bitcoin update contains a malicious bug that was not detected in the Bitcoin protocol despite careful testing and review of the peer-to-peer network. The network will likely crash for a short period of time. This could lead to a drastic drop in the price of Bitcoin and a fork of the blockchain.
    Bitcoin is decentralized and therefore theoretically cannot be banned by any single government. However, there have been attempts in the past to ban cryptocurrencies or limit their use. Since one government cannot do much on its own, several governments can work together to push for a ban on cryptocurrencies. However, it is highly likely that governments will pass laws to protect investors and tax laws.
    A 51% attack represents an unexpected but serious threat, however, for such an attack to be successful, not only 51% of network participants would be required, but also a huge investment in mining equipment. It will be necessary. In addition to these factors, it is highly unlikely that such a majority will occur, as network participants will also risk their profits.
    Additionally, new and supposedly better cryptocurrencies are introduced to the markets almost daily. Such developments risk market fatigue when it comes to investing. This means that once all the investors

    Why are bitcoins stolen?

    Most cryptocurrency thefts involve users and websites that do not take proper precautions when storing them. Often, coins that are kept in places where they are not safe are stolen.
    For example, a “hot wallet” is any cryptocurrency wallet that is connected to the Internet or “online” in some way. Hot wallets are wallets on desktop or mobile devices, as well as wallets hosted by an exchange that has failed to keep its security measures up to date. A hot wallet can also refer to wallet private keys that are carelessly stored on a compromised, hackable device.
    Cryptocurrencies are stolen because they are stored in unsecured locations.
    The Mt.Gox hack is perhaps the biggest example of poor security precautions and the biggest theft of cryptocurrencies. Mt Gox was an exchange founded in Japan and converted to a Bitcoin exchange in 2010. Due to lack of security measures, more than 850,000 BTC were stolen. Mt. Gox hack is the biggest hack since the creation of Bitcoin and led to the bankruptcy of the exchange in 2014.
    Fortunately, other exchanges around the world learned from this incident and have since kept their security measures up to date. However, we recommend that all cryptocurrency users practice prudent security habits and read our article on how to store cryptocurrencies safely.
    Although certain security precautions must be taken, blockchain technology with its distributed database is one of the most innovative and important innovations to date. Blockchain technology opens the door to many applications that are just waiting to conquer the world.

    What does “cryptojacking” mean and what can I do about it?

    In cryptojacking, cryptojackers use your computer or smartphone to mine cryptocurrencies using malware.
    • Cryptojackers get cryptocurrencies on your computer without you noticing.
    • Cryptojacking can be done through your browser and without additional malware.
    • Cryptojacking is quick to detect and easily preventable.
    In this lesson you will learn about the dangers of cryptojacking.
    • How does cryptojacking work?
    • How can I protect myself from cryptojacking?
    • Should in-browser mining of cryptocurrencies always be viewed critically?

     

    Mining Bitcoin and other cryptocurrencies is as energy and computing intensive as it is profitable. So, it was only a matter of time before fraudsters on the Internet developed ways to abuse the computing power of other users’ computers for their own financial gain. This process is known as “cryptojacking” – an apt term to describe a combination of cryptocurrency and hijacking.
    By being a victim of cryptojacking, you allow cryptojackers to use your computer’s processing power and electricity for mining.

    How does cryptojacking work?

    The concept of cryptojacking is simply explained. You visit a website and as you browse it, a malware script runs in the background. This script usually consists of a few lines of JavaScript code, which then silently starts mining CPU-heavy, anonymity-based cryptocurrencies like Monero using your computer or smartphone.
    As a victim of cryptojacking, you are allowing cryptojackers to use your computer’s computing power and power supply for mining without you noticing.
    There have also been reports of Chrome browser extensions being infected and then removed from the Chrome Web Store.

    How can I protect myself from cryptojacking?

    To be protected from cryptojacking through your browser, you actually only need to install free browser extensions like MinerBlock (Chrome) or KoiCoin (Chrome and Firefox).
    Some users see legitimate, voluntary in-browser cryptocurrency mining as an alternative monetization model that could potentially replace advertising on websites.

    Should in-browser mining of cryptocurrencies always be viewed critically?

    Not required. Some users even see legitimate, voluntary cryptocurrency mining as an alternative in-browser monetization model that could potentially replace ads on websites.
    For example, users may choose to view ads or knowingly give away a small portion of their computing power to receive a certain cryptocurrency as payment to avoid ads. The same applies to non-profit organizations, which can for example collect donations by asking visitors to install an application or stay on their website.
