We must regain control! 6 What’s wrong with Apt/Yum/Pacman/etc.? Global state (/usr) that prevents multiple versions of a package from coexisting. Non-atomic installation, removal, upgrade of software. No way to roll back. Nondeterminstic package builds and maintainer-uploaded binaries. (though this is changing!) Reliance on pre-built binaries provided by a single point of trust. Requires superuser privileges. 7 The problem is bigger Proliferation of language-specific package managers and binary bundles that complicate secure system maintenance.

  • Ubuntu Kung Fu.Pdf
    Prepared exclusively for J.S. Ash Beta Book Agile publishing for agile developers The book you’re reading is still under development. As part of our Beta book program, we’re releasing this copy well before we normally would. That way you’ll be able to get this content a couple of months before it’s available in finished form, and we’ll get feedback to make the book even better. The idea is that everyone wins! Be warned. The book has not had a full technical edit, so it will con- tain errors. It has not been copyedited, so it will be full of typos and other weirdness. And there’s been no effort spent doing layout, so you’ll find bad page breaks, over-long lines with little black rectan- gles, incorrect hyphenations, and all the other ugly things that you wouldn’t expect to see in a finished book. We can’t be held liable if you use this book to try to create a spiffy application and you somehow end up with a strangely shaped farm implement instead. Despite all this, we think you’ll enjoy it! Throughout this process you’ll be able to download updated PDFs from your account on http://pragprog.com. When the book is finally ready, you’ll get the final version (and subsequent updates) from the same address. In the meantime, we’d appreciate you sending us your feedback on this book at http://books.pragprog.com/titles/ktuk/errata, or by using the links at the bottom of each page.

  • Independent Video Games and the Games ‘Indiestry’ Spectrum: Dissecting the Online Discourse of Independent Game Developers in Industry Culture By
    Independent Video Games and the Games ‘Indiestry’ Spectrum: Dissecting the Online Discourse of Independent Game Developers in Industry Culture by Robin Lillian Haislett, B.S., M.A. A Dissertation In Media and Communication Submitted to the Graduate Faculty of Texas Tech University in Partial Fulfillment of the Requirements for the Degree of DOCTOR OF PHILOSOPHY Approved Dr. Robert Moses Peaslee Chair of Committee Dr. Todd Chambers Dr. Megan Condis Dr. Wyatt Philips Mark Sheridan Dean of the Graduate School December, 2019 Copyright 2019, Robin Lillian Haislett Texas Tech University, Robin Lillian Haislett, December 2019 ACKNOWLEDGMENTS This is the result of the supremely knowledgeable Dr. Robert Moses Peaslee who took me to Fantastic Fest Arcade in 2012 as part of a fandom and fan production class during my doctoral work. This is where I met many of the independent game designers I’ve come to know and respect while feeling this renewed sense of vigor about my academic studies. I came alive when I discovered this area of study and I still have that spark every time I talk about it to others or read someone else’s inquiry into independent game development. For this, I thank Dr. Peaslee for being the catalyst in finding a home for my passions. More pertinent to the pages that follow, Dr. Peaslee also carefully combed through each malformed draft I sent his way, narrowed my range of topics, encouraged me to keep my sense of progress and challenged me to overcome challenges I had not previously faced. I feel honored to have worked with him on this as well as previous projects.
