Managing multiple Red Hat-based systems can be easy—with the right tools. The yum package manager and the Kickstart installation utility are full of power and potential for automatic installation, customization, and updates. Here’s what you need to know to take control of your systems.

Kickstart and yum are tools to automate installation, updates, and upgrades of Linux systems. Specifically, they operate on RPM-based Linux variants, such as the Red Hat Linux line (including the Enterprise and Fedora branches) and CentOS. Both tools have a learning curve and require some infrastructure for you to use them to their fullest extent.

As with any tool, it’s fair to ask, “What can it do for me? Why would I take the time to learn it?” My inspiration was, well, installing Fedora Core several times. To see what I mean, consider some of the information you enter when you install a Red Hat operating system (OS) by hand:

15. Głos studentów

Schutt, Rachel Helion ePub

Każdy algorytm to materiał wydawniczy.

—Emily Bell, dyrektorka Tow Center for Digital Journalism w Columbia University Graduate School of Journalism

Do współuczestnictwa w napisaniu niniejszego rozdziału zaprosiłyśmy studentów, którzy uczestniczyli w pierwszej edycji kursu „Wstęp do nauki o danych”[208]. Postanowili oni wykorzystać swój rozdział do podzielenia się swoimi przemyśleniami i wrażeniami na temat tego kursu. Współautorami rozdziału są: Alexandra Boghosian, Jed Dougherty, Eurry Kim, Albert Lee, Adam Obeng i Kaz Sakamoto.

Kiedy studiujesz naukę o danych, nie możesz zacząć od niczego innego, jak tylko od rzeczy najnowszych.

Wstępny wykład z fizyki zazwyczaj obejmuje mechanikę, elektryczność i magnetyzm, i może jeszcze coś ze „współczesnych” tematów, jak szczególna teoria względności. Tematy są prezentowane ogólnikowo, w porządku narastającej trudności. W takim ujęciu nagromadzonych i złożonych koncepcji, w dokładaniu kolejnych faktów brakuje jednak wejrzenia w to, jak — dajmy na to — Newton wpadł na pomysł rachunku różniczkowego. Nie uczy się nas o sposobie jego postępowania, o tym, jak na to wpadł. Nie poznajemy jego narzędzi ani przemyśleń. Nie dowiadujemy się, jakie książki czytał, ani czy robił notatki. Czy próbował odtwarzać dowody innych? Czy skupiał się na problemach wynikających z tego, co napisał wcześniej? Co kierowało jego tokiem myślenia: „Nie mogę tego zrobić bez pojęcia nieskończenie małego?”. Czy Newton szkicował coś na papierze? A może w pełni uformowane pomysły przychodziły mu do głowy znienacka, jak wtedy, gdy ujrzał spadające jabłko? Tego się nie uczy, lecz powinno się tego uczyć, bo daje to wskazówkę, jak początkujący naukowcy powinni postępować.

9: The “Maximum Eligible Participation” Solution

Wade Rathke Berrett-Koehler Publishers ePub

There may be a national consensus around the value of the Earned Income Tax Credit program that ensures its continuance, and perhaps even its expansion, but other programs wish they could find as much love. To build citizen wealth, we need to aggressively use all existing programs, no matter how many scars and warts they may have, because the passage of new initiatives is at the least years away. Many of these programs do not have the same level of support as EITC, which policy makers and politicians can defend as supporting hard-working families. Some, like the Food Stamp program, have supportive constituencies, but others were avowedly created to share the wealth of the nation with the poorest of its citizens and thereby provide some small share of family security.

There was a phrase from the 1960s that became a government mandate devised by Richard Boone calling for “maximum feasible participation” of the poor in a series of programs. Boone was not talking about benefits but empowerment.1 I would like instead to talk about a modern adaptation of this slogan—”maximum eligible participation.” We need a vision of maximum eligible participation and a campaign to achieve it as galvanizing as the movement for civic participation of the poor became in the old Office of Economic Opportunity (OEO). We need to create ways to ensure that all individuals and families eligible for any program or entitlement actually receive them. Such a situation would be empowering as well. As we can see in the current governmental bailout of the banking system, there is now no such concept as “breaking the bank,” but we need to imagine a concerted effort by government, organizations, and individuals to enable eligible families to get access to the “bank” of benefits that is lawfully theirs.

Antwerp • Bruges • Brussels • Ghent





The largest metropolis in Belgium is Antwerp, which is situated in the province of Flanders (of which it is the capital). Blessed with a rich history, the city of Antwerp had its first origins as a Gallo-Roman settlement, dating to approximately the 3rd century. It was later settled by the Franks (4th century), and saw Spanish rule in the 17th century. Today, the city of Antwerp is both financially and culturally prosperous. The city is also known for the impressive merchant houses of the 16th century, a large number of which managed to survive both fire and World War II bombings.

The Het Steen (a medieval fortress) stands proud in the midst of the city, providing a fitting location for the popular Museum of Archaeology, and St James Church is known for being the final resting place of the 17th-century artist Rubens.


Founded in 1810, the Koninklijk Museum voor Schone Kunsten Antwerpen (Antwerp Royal Museum of Fine Arts) is home to a collection of sculptures, paintings, and drawings dating from the 14th to the 20th centuries. Although now temporarily closed for renovation (until 2017) the collection can still be seen at various locations around Antwerp and Belgium. The collection itself is a prime example of art from Belgium and the Northern and Southern Netherlands from the 15th century. Throughout the renovation, the collection will be on display at the Cathedral of Our Lady in Antwerp, the Municipal Museum in Lier, and Schepenhuis in Mechelen.

9: Psychology for the Legislated

Sara Brill Indiana University Press ePub

THE ATHENIAN'S TURN to penal law begins with a lament that such legislation is necessary in Magnesia (853b). However, he quickly acknowledges that they are humans legislating for humans, and that the account of human nature and the human soul they have been developing reveals the necessity for laws of the sort they are about to create. The structure of these laws is informed by another early agreement, namely, that the account of the soul that informs the legislators’ approach to legislating is to be shared with the legislated (645b–c). As we have seen, the preludes that are appended to laws are treated as a powerful vehicle for conveying this civically salutary conception and attitude toward soul. This chapter will argue that the preludes attached to penal law are particularly vivid instantiations of this psychology for the legislated. We will begin with the prelude to temple robbing, a piece of legislation which directly precedes and motivates the distinction between injury and injustice that so shapes Magnesian homicide law, and which promotes precisely the attitude toward violent action that is encapsulated by the religious language of pollution. From there we will move on to discuss the legislation pertaining to homicide and the impiety of the young in order to analyze the implicit accounts of soul contained therein.
