Etat czy B2B dla IT - Programista
Kinga Jańczak
Etat czy działalność – to dylemat, przed którym stoi nie jeden programista. Publikacja przedstawia kalkulację opłacalności etatu i pracy w modelu B2B z uwzględnieniem rewolucji podatkowej wynikającej z wejścia w życie Polskiego Ładu. Opracowanie w prosty sposób tłumaczy zawiłości w przepisach, obrazując je w formie konkretnych przykładów wykorzystujących spotykane w branży kwoty. Dzięki takiemu podejściu publikacja stanowi: • symulację składkowo-podatkową w przypadku zatrudnienia na podstawie umowy o pracę, • kalkulację dostępnych form opodatkowania dla programistów w przypadku działalności gospodarczej. Po przeczytaniu opracowania, nie będziesz miał już żadnych wątpliwości czy wybrać etat, czy własną działalność gospodarczą.

We'll also delve into the mechanisms of advanced smart contracts, taking a practical approach.You'll also learn how to develop your own cryptocurrency from scratch in order to understand the business behind ICO. Further on, you'll get to know the key concepts of the Solidity programming language, enabling you to build decentralized blockchain-based applications. We'll also look at enterprise use cases, where you'll build a decentralized microblogging site. At the end of this book, we discuss blockchain-as-a-service, the dark web marketplace, and various advanced topics so you can get well versed with the blockchain principles and ecosystem.
Ethernet. Biblia administratora
Charles E. Spurgeon, Joann Zimmerman
Kompendium wiedzy o sieciach Ethernet! Biblia administratora sieci Ethernet! Standard Ethernet powstał w 1976 roku w ośrodku badawczym firmy Xerox. Wykorzystywany do budowy sieci lokalnych, znajduje zastosowanie praktycznie w każdym miejscu. Sieci Ethernet spotkasz zarówno w mieszkaniach czy domach, jak i w biurach czy centrach danych. W zależności od budżetu, jakim dysponujesz, możesz zbudować sieć dostosowaną do własnych potrzeb. Nowoczesne sieci Ethernet pozwalają na niezawodne przesyłanie danych z ogromnymi prędkościami. W Twoje ręce oddajemy biblię wiedzy o sieciach Ethernet, która odpowie na wszystkie nurtujące Cię pytania oraz zaprezentuje nowoczesne techniki wykorzystania tych sieci. Przekonasz się, jak wygląda proces automatycznej negocjacji oraz jak zasilać urządzenia za pomocą Ethernetu. W kolejnych rozdziałach znajdziesz charakterystyczne elementy popularnych sieci 10, 100 i 1000 Mb/s oraz niezwykle wydajnych sieci o prędkości dochodzącej do 400 Gb/s. Trzecia część tej książki została poświęcona budowie systemu Ethernet. Poznasz tu systemy okablowania strukturalnego, dostępne kable, złącza oraz przełączniki. Książka ta jest obowiązkową pozycją na półce każdego administratora, który chce poznać swoją sieć od podszewki. Dzięki tej książce: poznasz historię standardu Ethernet zrozumiesz zasadę jego działania zobaczysz, jaki potencjał kryją sieci Ethernet nauczysz się projektować wydajne rozwiązania poznasz tajniki działania Twojej sieci

ETL is one of the most common and tedious procedures for moving and processing data from one database to another. With the help of this book, you will be able to speed up the process by designing effective ETL solutions using the Azure services available for handling and transforming any data to suit your requirements.With this cookbook, you’ll become well versed in all the features of SQL Server Integration Services (SSIS) to perform data migration and ETL tasks that integrate with Azure. You’ll learn how to transform data in Azure and understand how legacy systems perform ETL on-premises using SSIS. Later chapters will get you up to speed with connecting and retrieving data from SQL Server 2019 Big Data Clusters, and even show you how to extend and customize the SSIS toolbox using custom-developed tasks and transforms. This ETL book also contains practical recipes for moving and transforming data with Azure services, such as Data Factory and Azure Databricks, and lets you explore various options for migrating SSIS packages to Azure. Toward the end, you’ll find out how to profile data in the cloud and automate service creation with Business Intelligence Markup Language (BIML).By the end of this book, you’ll have developed the skills you need to create and automate ETL solutions on-premises as well as in Azure.

Event-driven architecture in Golang is an approach used to develop applications that shares state changes asynchronously, internally, and externally using messages. EDA applications are better suited at handling situations that need to scale up quickly and the chances of individual component failures are less likely to bring your system crashing down. This is why EDA is a great thing to learn and this book is designed to get you started with the help of step-by-step explanations of essential concepts, practical examples, and more.You’ll begin building event-driven microservices, including patterns to handle data consistency and resiliency. Not only will you learn the patterns behind event-driven microservices but also how to communicate using asynchronous messaging with event streams. You’ll then build an application made of several microservices that communicates using both choreographed and orchestrated messaging.By the end of this book, you’ll be able to build and deploy your own event-driven microservices using asynchronous communication.
