Last week, I described how to add a dynamic watermark to your images on the JVM. I didn't find any library, so I had to develop the feature, or, more precisely, an embryo of a feature, by myself. Depending on your tech stack, you must search for an existing library or roll up your sleeves. For example, Rust offers such an out-of-the-box library. Worse, this approach might be impossible to implement if you don't have access to the source image. Another alternative is to use ready-made components, namely imgproxy and Apache APISIX. I already combined them to resize images on-the-fly. Here's the general sequence flow of the process: When APISIX receives a specific pattern, it calls imgproxy with the relevant parameters
imgproxy fetches the original image and the watermark to apply
It watermarks the original image and returns the result to APISIX Let's say the pattern is /watermark/*. We can define two routes: routes:

IBM 1401 Programming Systems by Anonymous is part of the HackerNoon Books Series. You can jump to any chapter in this book . IBM 1401 Programming Systems here IBM 1401 Programming Systems P PR PRO SYSTEMS PROG YSTEMS PROGR STEMS PROGRA TEMS PROGRAM EMS PROGRAMM MS PROGRAMMI S PROGRAMMIN PROGRAMMING When companies order an IBM 1401 Data Processing System, methods-programming staffs are given the responsibility of translating the requirements of management into finished applications. 1401 Programming Systems are helping cut the costs of getting the computer into operation by simplifying and expediting the work of these methods staffs. Modern, high-speed computers, such as the 1401, are marvelous electronic instruments, but they represent only portions of data processing systems. Well-tested programming languages for communication with computers must accompany the systems. It is through these languages that the computer itself is used to perform many of the tedious functions that the programmer would otherwise have to perform. A few minutes of computer time in translating the program can be equal to many, many hours of staff time in writing instructions coded in the language of the computer. The combination of a modern computer plus modern programming languages is the key to profitable data processing. This brochure explains modern IBM Programming Languages and their significance to management. : Here an operator points to machine language instructions for a new application being generated by the 1401 system on the 1403 high-speed printer. Statements about the application which were written by the programmer are being translated internally to machine-coded language. Page 2 " " What Is A 1401 Program? A program is a series of instructions that direct the 1401 as it solves an application. " " What Is A Stored Program Machine? A stored program machine is one which stores its own instructions in magnetic form and is capable of acting on those instructions to complete the application assigned. The 1401 uses a stored program. " " What Are 1401 Programming Systems? There are two types: (1) Systems that provide the programmer with a simplified vocabulary of statements to use in writing programs, and (2) Pre-written programs, which take care of many of the everyday operations of the 1401. What 1401 Programming Systems Mean To Management: INCREASED PROGRAMMING EFFICIENCY Programmers can concentrate on the application and results rather than on a multitude of "bookkeeping" functions, such as keeping track of storage locations. FASTER TRANSLATION OF MANAGEMENT REQUIREMENTS INTO USABLE RESULTS Simplified programming routines allow programmers to write more instructions in less time. SHORTER TRAINING PERIODS Programmers use a language more familiar to them rather than having to learn detailed machine codes. REDUCED PROGRAMMING COSTS Many pre-written programs are supplied by IBM, eliminating necessity of customers' staffs writing their own. MORE AVAILABLE 1401 TIME Pre-written programs have already been tested by IBM, reducing tedious checking operations on the computer. EASIER TO UNDERSTAND PROGRAMS Programs are written in symbolic or application-oriented form instead of computer language. This enables management to communicate more easily with the programming staff. FASTER REPORTS ON OPERATIONS Routines such as those designed for report writing permit faster translation of management requirements into usable information. IBM Programming Systems Symbolic Programming Systems These systems permit programs to be written using meaningful names (symbols) rather than actual machine language. Autocoder This is an advanced symbolic programming system. It allows generation of multiple machine instructions from one source statement, free-form coding, and an automatic assembly process through magnetic tape. COBOL COBOL is a problem-oriented programming language for commercial applications. COBOL permits a programmer to use language based on English words and phrases in describing an application. [A] Input/Output Control System This system provides the programmer with a packaged means of accomplishing input and output requirements. Utility Programs These are pre-written instructions to perform many of the everyday operations of an installation. Subroutines These are routines for multiplication, division, dozens conversion, and program error detection aids. Tape Utilities These are generalized instructions, particularly useful to 1401 customers who also use larger data processing systems. They facilitate the transfer of data between IBM cards, magnetic tapes, and printers. They also provide for some 1401 processing while the transfer of data is taking place. Tape Sort Programs Data can be sorted and classified at high speed for further processing by use of these generalized sorting routines. Report Program Generator The programmer uses simplified, descriptive language with which he is already familiar to obtain reports swiftly and efficiently. FORTRAN ( FOR TRAN ) Contraction of mula slator Engineers and mathematicians state problems in familiar algebraic language for solution by the computer. RAMAC® File Organization Routines are supplied for simplifying organization of records for storage in the 1401 Random Access File. Here's how one of the 1401 programming systems—Report Program Generator—works to increase programming efficiency 1401 computers produce important reports for management in record time because of their outstanding processing and printing abilities. In addition to this rapid machine processing of used in reports, still more speed is achieved by the rapid preparation of to produce the reports. This is possible because of the IBM Report Program Generator, a unique system which permits programs to be created with a minimum of time and effort. input data programs This example illustrates how the Report Program Generator simplifies the preparation of one part of an Expense Distribution Report (The Major Total Line): Without the Report Program Generator, the program to get the Major Total Line would be written out in detail, step by step: But with the Report Program Generator, all the programmer has to write are these two statements: It's just as easy to write the statements to generate the rest of the report! The 1401 itself does the work of converting the programmers' statements into the detailed instructions. The Report Program Generator is an example of what IBM Programming Systems can accomplish. With IBM you can be certain of total systems support for maximum profitability. IBM® Stands For Service Service that begins long before the delivery of a computer ... and continues in depth long after. Service that has been by years of data processing experience. proven New IBM Services include: Programmed Applications Library Pre-tested computer programs designed to handle various major data processing functions common to firms within a specific industry.

On my current project, I work with protobuf not only for GRPC, but also as message format. While the advantages of protobuf are not limited to its speed, I was wondering if it's really so fast compared to libraries, especially in the ruby world. I decided to make some benchmarks to check it, but first I want to add a brief introduction to each format. RabbitMQ JSON What is protobuf? It's a fast, compact cross-platform message system, designed with forward-and backward compatibility in mind. It consists of a definition language and language-specific compilers. It works perfectly for small object-like data, has great backward and forward compatibility, is fast(we are not sure yet), and is more compact than JSON, for example, but have some limitations like not supporting direct comparison(you need to deserialize objects to compare). It's not compressed and some specific formats can work better for their data(for example JPEG). It's not self-describing. See for more details. Official docs What is JSON JSON is an abbreviation for . A text-based data format, which was originally used in JavaScript, but later got widely spread as a communication format not only between JS apps and backend but even between microservices and has multiple other usages. JavaScript object notation It uses strings as keys and has a string, number, boolean, object, array and nul as available types for value. The main advantage of it is that it is human-readable, and pretty easy to serialize and parse for programming language. See the for more details. site Benchmarks I picked up three popular ruby JSON libraries. They are Oj, Yajl, and standard JSON library. For protobuf, I use standard google protoc with google ruby gem. I will measure different specific types of payload to see which data type we will show the most difference, as long as complex payload with a mix of field types. You can see all the code here . https://github.com/alexstaro/proto-vs-json Benchmark setup As a hardware I use laptop with AMD Ryzen 3 PRO 5450U and 16gb of ddr4 ram. As an operating system, I use Ubuntu 22.10 kinetic. Ruby version 3.2.1 was installed via asdf. For benchmarking, I use benchmark/ips gem ( ) https://github.com/evanphx/benchmark-ips The setup looks like this: Benchmark.ips do |x|  
  x.config(time: 20, warmup: 5)  
  
  x.report('Yajl encoding') do  
    Yajl::Encoder.encode(data)  
  end  
  ...
  x.compare!  
end Integers only We will start with only integers. Numbers are pretty hard for JSON so we expect protobuf to be far away from other competitors. The test data: data = {

standard JSON encoding:   505697.5 i/s - 8.20x  slower
       Yajl encoding:   496121.7 i/s - 8.36x  slower There is no doubt that protobuf is an absolute winner, but what if we make the test more closer to the real-world scenario - we almost always create proto messages only for serialization. What would happen if we move model initialization under benchmark? Here are the results: protobuf encoding:  4146929.7 i/s
         Oj encoding:  1885092.0 i/s - 2.20x  slower

protobuf with model init:   489658.0 i/s - 8.47x  slower The result is not so obvious. I expected encoding with message initialization would be slower but not the slowest. Let's check deserialization: protobuf parsing:   737979.5 i/s
          Oj parsing:   448833.9 i/s - 1.64x  slower
standard JSON parsing:   297127.2 i/s - 2.48x  slower
        Yajl parsing:   184361.1 i/s - 4.00x  slower There are no surprises here. In terms of payload size, protobuf is almost 4 times more compact compared to json: JSON payload bytesize 201
Protobuf payload bytesize 58 Doubles only Doubles are expected to be the hardest payloads for JSON, let's check this out. Our payload: data = {

Protobuf payload bytesize 876 We see here the expected behavior with pure protobuf encoding on the first place, however, if we look at our “real-world” example we see it is not faster that the standard JSON encoding. Conclusion If you are switching from JSON to Protobuf just for the speed, it's may not worth it. The reason to use Protobuf should be the awesome cross-language schema definition for data exchange — not a performance boost.

How to Become a Front-End Developer: Skills, Resources, and Career Roadmap 

FinTech is a growing industry at the intersection of technology and financial services. This is a powerful incentive for technological progress, which expands its influence on different sectors of the economy, allowing them to develop. For example, FinTech has been most active in consumer services, banking, money transfers, payments, insurance, asset and capital management. The industry is revolutionizing the way businesses and consumers conduct financial transactions. In 2020, businesses continue to develop in digital-native scenarios: the consumer lives the digital experience, and businesses are built among platforms and ecosystems, companies can influence user behaviour more effectively and faster. Here are 3 main FinTech trends that contributed to these processes. Enhancement of customer experience in banking servicesNew banking products. Crossing of financial products Rising popularity of cryptocurrencies I suggest you quickly review each of them. This will allow us to better understand the looming trends and see the connection in this regard between 2020 and 2021 years. FinTech 2020, a Retrospective: Enhancement of customer experience in banking services In my opinion, nowadays many banks are still in the same position as before when they chose to provide customer service or not and still had a good profit. Gradually they find themselves in a situation where they need to look for a revenue stream and therefore try to maximize the number of their customers, as the margin of their products falls. Today it is not the bank but the client who chooses. The modern client is interested not as much in a good bank rate or the price of banking service, but in the convenience and speed of using the bank, the ability to work with the bank only remotely (especially during the COVID-19 pandemic), the availability of a good mobile application with various services for family, work and study. An important criterion is whether the bank has a high-quality KYC service to recognize the identity of the counterparty. New banking products. Crossing of financial products The S-PRO team is currently developing a product for an American company operating in the African market. And transport paying products are gaining popularity there, for example, special bank cards. The number of such products is growing, as is the competition. This is a trend related to the first trend – customer experience. People need a lighter digital experience, which often involves paying for something. When a person wants to buy a product in instalments online, it’s also a fintech story but it happens at the intersection of eCommerce and fintech. Banks used to hold the whole market, but today they have a lot of competition from startups. Young companies are more flexible, they see customer prospects faster, and they don’t need to do extensive analysis. In addition, there are many young talents who can and want to create something. Banks, in turn, are also interested in this, because they invest in such young companies and then can buy them. Here the issues are in the framework of collaboration with new players – large banks are already able to cooperate with startups. But middle-class banks still need to learn to do the same. Startups are actively becoming distributors of banking services. Of course, banks are still trying to create their own financial products, such as banking products for accountants, for opening a new company, etc. Cryptocurrencies become more popular The third trend is cryptocurrencies, a subsection of trends 1 and 2, I would say. In 2020, this fintech product continued to penetrate the banking sector. And cryptocurrencies appeared precisely because of customer experience. For people who need dynamics, speed and simplicity, such products are more convenient for payments. And in some areas, Bitcoins or Ethereums are best suited for this. There is an increase in the number of companies that conduct their business exclusively through Bitcoins or Ethereums. Cryptocurrencies have good financial turnovers and need strong operating activities and convenient banking services. But at the same time, it’s difficult for them to get legal and to get normal bank accounts. Today there are more and more cryptocurrency startups that work in financial services, payment processing, and software. They work as a wallet service, can securely store cryptocurrency from a range of different attacks, support all cryptocurrencies as well as do a decentralised exchange and provide many different opportunities: Cobo, Javvy, Finhaven, Digital Currency Group, Binance, and others. By the way, among our projects is a digital-bank, which works with large crypto companies, and provides them with various banking services. This is when you can come and put cryptocurrency in the bank. Also, you can get legal financing through a bank, but in cryptocurrency. Impact of the COVID-19 pandemic on the FinTech industry In general, the impact of the coronavirus outbreak on the industry depends on how much money banks make from their offline services and how they can operate online. The share of online banks is likely to have increased, while that of offline banks has decreased. Different banks operate in different industries, with their own area of expertise. Some provide B2B services, others have certain products, and others just have a bank for the population. During the first wave of Covid-19, the impact of the pandemic on the banking sector was negative, as turnover, orders and profits fell in many companies. Demand for bank loans decreased, and banks earned less on lending. In this situation, in order to maintain a positive level of profits, banks increase the fee for certain financial activities and services and develop Internet banking, including mobile banking. Citizens are increasingly shopping online and making payments through electronic banking. Among other things, since the beginning of the pandemic, the WHO (World Health Organization) recommends the use of contactless payments. Even before the outbreak of the coronavirus, the demand for digital banking grew due to the lack of time and desire to contact the physical branches of banks. The pandemic has stimulated the development of online banking platforms to make every banking service available online. Fintech trends in 2021. What is expected? 1. Improving customer experience In 2021, in the field of banking, there will be an emphasis on improving the customer experience, KYC, and onboarding processes. Work with mobile applications, chatbots, automation will also be aimed at improving interaction with users. Obviously, banking services will become more and more friendly. A bank that wants to develop should not squeeze money out of the client, but score the client before providing financial products, check their solvency by improving the work with credit ratings. Today, this is a well-worked practice, but credit scoring models will be revised. The bank’s task is to give more value to the customer through various services. Thus, the bank will be able to earn not only on its main services, such as saving money or lending but also on additional ones – insurance sales, delivery, etc. The insurance industry has worked extensively with personal and business transportation and travelling. Now, these areas have fallen due to lockdown. In 2021, insurtech is likely to focus on health insurance and on improving the customer experience. “In 2021, in the field of banking, there will be an emphasis on improving the customer experience, KYC, and onboarding processes.” 2. Increasing investment in the healthcare sector Healthcare is now at the forefront of technological innovation and financial systems, providing investors with promising growth opportunities throughout the market cycle. This growth continues because of the increasing prevalence of chronic diseases and the ageing population. And of course, COVID-19 isn’t the last reason for this. The healthcare sector is very large and offers a wide range of options for investors. Medical devices, pharmaceuticals, life sciences, and biotechnology have fairly reliable, good sales and profit indicators. Therefore, investment in healthcare is expected to increase. People are paying more attention to their physical and mental health and buying more expensive insurance. Obviously, there will be new technological challenges in this industry. And it’s logical that telemedicine will continue to develop. 3. Responsible banking: improvement of working methods with debtors According to my observations, it so happens that people don’t pay the loan because of the lack of money, but because they simply forget. The bank can be more effective in dealing with debtors if it’s able to interact properly with them through mobile applications, chatbots, or automatic write-offs, rather than through collectors. Within the projects we’re working on, the trend of resale of loans is becoming obvious. There are many lending platforms for microcredit. Such small platforms work very effectively with clients, they understand how to sell and collect these loans well. But they have a significant problem – limited access to finance. So they can’t borrow a lot of money and scale. As a result, specialized companies are emerging to help banks and these microcredit platforms, as well as startups in other financial sectors. Among our projects is the scoring of loans issued by lending platforms, and giving other institutions the opportunity to invest in these loans through API. This is what the reselling of loans looks like, and it can be done automatically. Standard mechanisms of interaction in the Intermarket space between small borrowers and banks or investment funds are being created. With the help of these scoring products and automated APIs, you can invest money in one loan or in a set of loans at once. These platforms create a variety of package offers and tools to analyze where it’s best to invest. And the margin of such investments can be quite high. We cooperate with one major sports association and within this project, we make a wallet for athletes, in particular for children. That is, the financial product integrated into the field of sports. Children have access to information on the entire sports infrastructure and can use it through a special mobile application. Parents can financially regulate the child’s access to certain sections. “The bank can be more effective in dealing with debtors if it’s able to interact properly with them: through a mobile application, chatbots, or automatic write-offs, rather than through collectors.” 4. Development of hybrid solutions in fintech Fintechs, which originated as monoproducts, are fighting for a leading role in the entire financial system. To do this, they create multi-solutions. For example, innovative banks are expanding their digital product line to become more versatile and offer hybrid products such as investment cards and smart deposits. For the user, the value of hybrid products is that such solutions help to take the first step towards savings. In particular, hybrid solutions help to use the current account more competently and at the same time not to save too much. Different mechanics are used for this purpose: rounding of purchase and transfer of “change” to the digital account, robotic investment, etc. Hybrid products are more marginal because they are easier to use. They give added value to the customers, for which they are ready to pay more. And for a financial institution, successfully crossed products are an additional revenue stream. 5. Support and digitization of the African region Today most Africans don’t have bank cards or pay in cash. We’re doing one project with a startup – a payment service in the field of urban mobility. People on the streets will receive cards to pay for transport. The registration procedure is simple and is carried out in seconds right at the bus stops. And then the user can pay with this card for other purchases and services. But the mobile application itself is made so that a person can call a taxi or get on the bus in time. In short, it’s created for the convenient use of transport. By and large, there is a tendency to digitize services for the African population. This large region is interesting for investment. The African market is strategically interesting both for countries and for companies, so business goes there from different directions. There are social initiatives to work with the population, as well as to create appropriate conditions for doing business. Africa is the next China. The development of the financial area, social projects, health care, and renewable energy are forecast. “The African market is strategically interesting both for countries and for companies, so business goes there from different directions.” I know how hard it is sometimes to overcome a long read. So today I will save your time and leave a little intrigue. The next 5 fintech trends in 2021 we will discuss in more detail very soon in the second part of this article. Also published here .
