Bardziej niż Agile. Jak zwiększyć innowacyjność twojego biznesu

Marcin Żmigrodzki

Efektywna innowacyjność w biznesie jest możliwa! Rozwój firm - od startupów do korporacji ― nie jest możliwy bez wprowadzania nowych pomysłów w życie. Jednak wiele z nich po wdrożeniu okazuje się nie przynosić korzyści, bo albo nikt nie chce kupić nowego produktu, albo wprowadzone rozwiązanie techniczne nie dostarcza spodziewanej wartości. Ponad 90 procent startupów bankrutuje, połowa firm, które 20 lat temu były na liście Fortune 500, już nie istnieje i jedną z głównych przyczyn tego stanu rzeczy jest niewystarczająca innowacyjność. Czy zatem skuteczniejszą strategią biznesową byłaby rezygnacja z innowacyjności i pozostanie przy tym, co może nie działa najlepiej, ale przynajmniej jest znane i sprawdzone? A może lepszym wyjściem byłoby generowanie mnóstwa pomysłów w nadziei, że przypadkiem uda się trafić na przełomową ideę? Nie, nie, po trzykroć nie! Biznes, by trwać i generować zyski, musi w dłuższej perspektywie bazować na wdrażaniu nowych idei, aby przynosiły wartość. Tajemnica sukcesu tkwi w tym, by owe idee weryfikować, odrzucać lub modyfikować na odpowiednim etapie, jeszcze zanim firma poniesie na nie duże wydatki. Takie podejście pozwala unikać strat i zarabiać na tych pomysłach, które faktycznie mają szansę odnieść sukces. Jak je wybrać spośród innych? Jak z powodzeniem przeprowadzić projekt eksploracyjny? Jak kontrolować projekt typu discovery, aby podążał za najlepszą opcją działania? Jak maksymalnie szybko uczyć się na doświadczeniach? W jaki sposób można użyć do tego narzędzia Agile? O tym wszystkim w swojej najnowszej książce pisze Marcin Żmigrodzki.

Bash Quick Start Guide. Get up and running with shell scripting with Bash

Tom Ryder

Bash and shell script programming is central to using Linux, but it has many peculiar properties that are hard to understand and unfamiliar to many programmers, with a lot of misleading and even risky information online. Bash Quick Start Guide tackles these problems head on, and shows you the best practices of shell script programming. This book teaches effective shell script programming with Bash, and is ideal for people who may have used its command line but never really learned it in depth. This book will show you how even simple programming constructs in the shell can speed up and automate any kind of daily command-line work.For people who need to use the command line regularly in their daily work, this book provides practical advice for using the command-line shell beyond merely typing or copy-pasting commands into the shell. Readers will learn techniques suitable for automating processes and controlling processes, on both servers and workstations, whether for single command lines or long and complex scripts. The book even includes information on configuring your own shell environment to suit your workflow, and provides a running start for interpreting Bash scripts written by others.

Bayesian Analysis with Python. Unleash the power and flexibility of the Bayesian framework

Osvaldo Martin

The purpose of this book is to teach the main concepts of Bayesian data analysis. We will learn how to effectively use PyMC3, a Python library for probabilistic programming, to perform Bayesian parameter estimation, to check models and validate them. This book begins presenting the key concepts of the Bayesian framework and the main advantages of this approach from a practical point of view. Moving on, we will explore the power and flexibility of generalized linear models and how to adapt them to a wide array of problems, including regression and classification. We will also look into mixture models and clustering data, and we will finish with advanced topics like non-parametrics models and Gaussian processes. With the help of Python and PyMC3 you will learn to implement, check and expand Bayesian models to solve data analysis problems.

Baza danych od środka. Analiza działania rozproszonych systemów danych

Alex Petrov

W ciągu ostatnich 15 lat powstało tak wiele baz danych i narzędzi, że łatwo się pogubić, jeśli próbuje się zrozumieć przypadki użycia, szczegóły i specyfiki. Większość opracowań na temat systemów baz danych nie opisuje implementacji mechanizmu pamięci masowej. Tymczasem znajomość tych wewnętrznych aspektów jest bardzo ważna dla programistów, inżynierów, architektów i menedżerów. Aby wybrać odpowiednie narzędzie do pracy, musisz zrozumieć idee i algorytmy stojące za ich projektem. Michael Klishin, współpracownik RabbitMQ Ta książka ułatwi Ci zgłębienie koncepcji kryjących się za działaniem nowoczesnych baz danych. Dzięki niej zrozumiesz, w jaki sposób struktury dyskowe różnią się od tych w pamięci i jak działają algorytmy efektywnego utrzymywania struktur B drzewa na dysku. Poznasz implementacje pamięci masowej o strukturze dziennika. Znajdziesz tu również wyjaśnienie zasad organizacji węzłów w klaster baz danych i specyfiki środowisk rozproszonych. Dowiesz się, jak algorytmy rozproszone poprawiają wydajność i stabilność systemu i jak uzyskać ostateczną spójność danych. Ponadto w książce zaprezentowano koncepcje antyentropii i plotek, służące do zapewniania zbieżności i rozpowszechniania danych, a także mechanizm transakcji utrzymujący spójność logiczną bazy. Najważniejsze zagadnienia: klasyfikacja i taksonomia pamięci masowej silniki pamięci masowej oparte na B-drzewie i niezmienna struktura dziennika struktura plików bazy danych pamięć podręczna stron i pule buforów systemy rozproszone: złożone wzorce komunikacji węzłów i procesów klastry baz danych Obowiązkowa lektura dla każdego, kto korzysta z jakiejkolwiek bazy danych!
