Implementowanie Czystej Architektury w Pythonie

Sebastian Buczyński

Zaawansowane programowanie zaczyna się tam, gdzie kończy się framework Praca programisty wydaje się dziś znacznie prostsza niż kilkanaście lat temu. Wydaje się taka, ponieważ ma on dostęp do niezliczonych bibliotek przypisanych do języków programowania. Gdy pojawia się problem, sięga do biblioteki ― i po sprawie. Problem rozwiązany, zgadza się? I tak, i nie. Owszem, w wypadku prostych projektów wystarczy bazowa znajomość zasad programowania, podstawowa znajomość danego języka i wiedza na temat tego, co zawiera konkretna biblioteka. Tak jednak działa to jedynie przy nieskomplikowanych aplikacjach. Bez wątpienia dziś łatwiej zacząć programować i szybciej można uzyskać mierzalne efekty, ale... ...prawdziwe programowanie zaczyna się poziom wyżej. Na etapie większych projektów. Bo duże systemy, niezależnie od języka, w jakim zostały napisane, zawsze są trudne ― zarówno w rozwijaniu, jak i w utrzymaniu. Książka, którą trzymasz w ręku, została napisana ze świadomością tej programistycznej prawdy. Adresowana do średnio zaawansowanych programistów zajmujących się rozwojem aplikacji internetowych, stanowi kompletny przewodnik po implementacji czystej architektury. Znajdziesz tu także opisy wielu technik, które pomogą Ci zapanować nad projektami rozwijanymi od dłuższego czasu, takich jak strategia testowania czy modularyzacja. Dzięki ich opanowaniu będzie Ci o wiele łatwiej dbać o poprawność funkcjonowania systemów, nad którymi sprawujesz programistyczną pieczę.

Informacja i kodowanie. Krótkie wprowadzenie z przykładami zastosowań

Wojciech Kordecki

Informacja i kodowanie. Krótkie wprowadzenie z przykładami zastosowań Wojciech Kordecki Naukę programowania zacznij od solidnych podstaw Jak sądzisz, co stanowi bazę informatyki? Od czego powinien zacząć przyszły programista? Może od opanowania jednego z najpopularniejszych języków programowania? Oczywiście mógłby od tego rozpocząć, tyle że to trochę tak, jakby uczyć się korzystać z narzędzia bez świadomości, do czego ono właściwie służy. Języki programowania to praktyka. Tymczasem niezbędną wiedzą, którą także powinien opanować każdy przyszły informatyk, są podstawy dotyczące teorii informacji i kodowania. Wraz z tą książką przyswoisz je bez konieczności odwoływania się do zaawansowanej matematyki i samej informatyki. Ten podręcznik obejmuje najważniejsze kwestie: od znaków, które przekazują informacje, źródeł informacji i sposobów mierzenia ilości przekazywanych danych po przetwarzanie sygnałów z analogowych na cyfrowe i odwrotnie. Po drodze zapoznasz się z takimi zagadnieniami jak podstawy kodowania (w tym kodowanie Huffmana), bezstratna kompresja i digitalizacja danych, grafiki i dźwięku, wreszcie konstrukcja kodów liniowych i cyklicznych.

Infrastruktura jako kod. Dynamiczne systemy w epoce chmury

Kief Morris

Sześć lat temu pojęcie infrastruktury jako kodu było czymś nowym. Dzisiaj, gdy nawet banki i inne konserwatywne organizacje planują przejść na korzystanie z chmury, zespoły programistów w firmach na całym świecie próbują budować duże bazy kodu infrastruktury. W swojej praktycznej książce Kief Morris z ThoughtWorks wyjaśnia, jak efektywnie zarządzać infrastrukturą w epoce chmury, używając zasad, praktyk i wzorców zainicjowanych przez zespoły DevOps. Nowe, uaktualnione wydanie, przeznaczone dla administratorów systemów, inżynierów infrastruktury, programistów, kierowników zespołów i architektów, pokazuje, jak wykorzystywać technologie chmury i automatyzacji do łatwego, bezpiecznego, szybkiego i odpowiedzialnego wprowadzania zmian. Czytając tę książkę dowiesz się, jak definiować wszystko jako kod i jak używać projektów oprogramowania i praktyk inżynieryjnych do tworzenia systemów składających się z małych, luźno sprzężonych elementów. Książka obejmuje następujące zagadnienia: •  Podstawy: wykorzystywanie infrastruktury jako kodu do ciągłego wprowadzania zmian i podnoszenia jakości operacyjnej za pomocą narzędzi i technologii przeznaczonych do budowy platform opartych na chmurze •  Stosy infrastruktury: sposoby definiowania, udostępniania, testowania i ciągłego dostarczania zmian zasobów infrastruktury •  Serwery i inne platformy: używanie wzorców do projektowania udostępniania oraz konfiguracji serwerów i klastrów •  Duże systemy i zespoły: przepływy, zarządzanie i wzorce architektoniczne używane do tworzenia elementów infrastruktury i zarządzania nimi   „Praktyki infrastruktury jako kodu przeszły ewolucję od zarządzania serwerami do zarządzania całymi stosami, ale ich nowe możliwości zostały osiągnięte kosztem złożoności. Książka wykracza poza same polecenia. Prezentuje wzorce projektowe kryjące się za dobrymi praktykami oraz metody automatyzacji na wyższym poziomie”. —Patrick Debois założyciel DevOpsDays Kief Morris jest globalnym dyrektorem ds. inżynierii chmurowej w ThoughtWorks. Pomaga organizacjom i zespołom szukać lepszych sposobów wykorzystywania technologii infrastruktury i chmury do szybszego i bardziej niezawodnego uzyskiwania większych korzyści. Od ponad 20 lat zajmuje się projektowaniem, tworzeniem i uruchamianiem zautomatyzowanej infrastruktury serwerów IT. Zaczynał od skryptów powłoki i Perla, a następnie, w miarę pojawiania się nowych technologii, przeszedł między innymi na CFengine, Puppet, Chef i Terraform.
