掌握比特币-开始赚取比特币的指导: New Moon (Vampyre Ser.)
by Adidas Wilson 顺宏比特币是由名不副实的程序员或者一群程序员发明的一种加密货币和数字支付系统，名叫Satoshi Nakamoto。 它在2009年作为开源软件发布。 系统是点对点的，交易是直接在用户之间进行的，没有中间人。 这些交易由网络节点验证，并记录在称为区块链的公共分布式账本中。 由于该系统没有中央存储库或单个管理员，比特币被称为第一个分散数字货币。 比特币除了被创造为挖矿的奖励外，还可以在合法或黑市交换其他货币，产品和服务。 截至2015年2月，超过10万商户和供应商接受比特币作为付款。 根据剑桥大学2017年的研究报告，使用加密货币钱包的用户数量达到2.9-580万，其中大部分使用比特币。
Γκέιμινγκ και βιντεοπαιχνίδια: Μια διαδραστική απόδραση από τη βαρεμάρα... (Πώς να... #95)
by Όουεν ΤζόουνςΓιατί το γκέιμινγκ αρέσει στους ανθρώπους; Εκατομμύρια επαγγελματίες και ανήσυχοι γονείς αναρωτιούνται το ίδιο εδώ και τουλάχιστον πενήντα χρόνια. Έχουν γραφτεί πολλά για το γιατί το γκέιμινγκ κατέκτησε τη νεολαία της δεκαετίας του '70 και γιατί, τώρα, άνθρωποι όλων των ηλικιών αγαπούν να παίζουν. Οι πληροφορίες σε αυτό το ηλεκτρονικό βιβλίο σχετικά με τα διάφορα είδη βιντεοπαιχνιδιών, τα παιχνίδια σε υπολογιστή, τα αρκέιντ κ.ά. είναι οργανωμένες σε 16 κεφάλαια των 500-600 λέξεων περίπου το καθένα. Ως μπόνους, σου δίνω την άδεια να χρησιμοποιήσεις το περιεχόμενο στον δικό σου ιστότοπο ή στα δικά σου ιστολόγια και ενημερωτικά δελτία, αν και είναι καλύτερα να το ξαναγράψεις με δικά σου λόγια.
كتاب العشق الإلكتروني
by عبدالله علي الأسمريكم كانت رائعة تلك اللحظة التي قررت فيها قبل عقد من الزمن أن أدلف إلى مقهى للإنترنت في قلب مدينة الرياض لأول مرة في حياتي. رأيت عامل المقهى وقد ارتسمت على وجهه ابتسامة عريضة وهو يقودني إلى مربع صغير يحوي طاولة انتصب عليها جهاز حاسوبي ذي شاشة عريضة. بدا المكان معزولا من ثلاث جهات أما الجهة الرابعة والتي يتم من خلالها الدخول فكانت عبارة عن باب صغير ينغلق بمجرد الدخول. بعد أن استويت على المقعد هرع العامل إلى أيقونة المتصفح browser ليطمس منه سجل المستخدم السابق وذلك - على ما يبدو - لكي لا أ لقي نظرة على ما كان يفعله من جاء قبلي. لم تسعفني خبرتي إذ ذاك في تفسر مغزى ذلك التصرف

Τέλεια γνώση του Bitcoin: Οδηγός κερδών στο Bitcoin για αρχάριους
by Adidas WilsonΤο Bitcoin είναι ένα κρυπτονόμισμα και σύστημα ψηφιακών πληρωμών που επινοήθηκε από κάποιον άγνωστο προγραμματιστή ή ομάδα προγραμματιστών, με το ψευδώνυμο Satoshi Nakamoto. Κυκλοφόρησε ως λογισμικό ανοικτού κώδικα το 2009. Το σύστημα στηρίζεται στη διομότιμη επικοινωνία, και οι συναλλαγές λαμβάνουν χώρα μεταξύ των χρηστών άμεσα, χωρίς μεσάζοντα. Οι συναλλαγές αυτές επαληθεύονται από δικτυακούς κόμβους, και καταγράφονται σε ένα δημόσιο κατανεμημένο καθολικό που ονομάζεται αλυσίδα συστοιχιών (blockchain). Επειδή το σύστημα λειτουργεί χωρίς κεντρικό αποθετήριο ή έναν μοναδικό διαχειριστή, το bitcoin χαρακτηρίζεται ως το πρώτο αποκεντρωμένο ψηφιακό νόμισμα. Παρότι έχει δημιουργηθεί ως αμοιβή για εξόρυξη, το bitcoin μπορεί να ανταλλαχθεί με άλλα νομίσματα, προϊόντα, και υπηρεσίες, είτε σε νόμιμες αγορές, είτε στη

10 Don'ts on Your Digital Devices: The Non-Techie's Survival Guide to Cyber Security and Privacy
by Daniel G. Bachrach Eric J. RzeszutIn nontechnical language and engaging style, 10 Don''ts on Your Digital Devices explains to non-techie users of PCs and handheld devices exactly what to do and what not to do to protect their digital data from security and privacy threats at home, at work, and on the road. These include chronic threats such as malware and phishing attacks and emerging threats that exploit cloudâe based storage and mobile apps. It''s a wonderful thing to be able to use any of your cloud-synced assortment of desktop, portable, mobile, and wearable computing devices to work from home, shop at work, pay in a store, do your banking from a coffee shop, submit your tax returns from the airport, or post your selfies from the Oscars. But with this new world of connectivity and convenience comes a host of new perils for the lazy, the greedy, the unwary, and the ignorant. The 10 Don''ts can''t do much for the lazy and the greedy, but they can save the unwary and the ignorant a world of trouble. 10 Don''ts employs personal anecdotes and major news stories to illustrate what can--and all too often does--happen when users are careless with their devices and data. Each chapter describes a common type of blunder (one of the 10 Don''ts), reveals how it opens a particular port of entry to predatory incursions and privacy invasions, and details all the unpleasant consequences that may come from doing a Don''t. The chapter then shows you how to diagnose and fix the resulting problems, how to undo or mitigate their costs, and how to protect against repetitions with specific software defenses and behavioral changes. Through ten vignettes told in accessible language and illustrated with helpful screenshots, 10 Don''ts teaches non-technical readers ten key lessons for protecting your digital security and privacy with the same care you reflexively give to your physical security and privacy, so that you don''t get phished, give up your password, get lost in the cloud, look for a free lunch, do secure things from insecure places, let the snoops in, be careless when going mobile, use dinosaurs, or forget the physical--in short, so that you don''t trust anyone over. . . anything. Non-techie readers are not unsophisticated readers. They spend much of their waking lives on their devices and are bombarded with and alarmed by news stories of unimaginably huge data breaches, unimaginably sophisticated "advanced persistent threat" activities by criminal organizations and hostile nation-states, and unimaginably intrusive clandestine mass electronic surveillance and data mining sweeps by corporations, data brokers, and the various intelligence and law enforcement arms of our own governments. The authors lift the veil on these shadowy realms, show how the little guy is affected, and what individuals can do to shield themselves from big predators and snoops. What you''ll learn After reading 10 Don''ts, you will understand how to: detect and report phishing scams choose better passwords and how to manage and safeguard all of them use cloudâe based storage services more safely shield your data from the prying eyes of government agencies, data brokers, corporations, and criminals steer through the risks of public wireless network, shared computers, and obsolete devices select and configure apps for your mobile devices without unknowingly compromising your privacy and security lock, safeguard, and erase your physical devices Who this book is for The primary target audience for 10 Don''ts is just about everybody--namely, non-techie individuals who routinely use computers, smartphones, and tablets in their daily lives but who are nagged by persistent worry that they are exposing themselves to personal insecurity, intrusive surveillance, and criminal violation. The secondary readerships for this book include employees of small businesses lacking dedicated IT specialists, whose owners want to give their workers a short and entertaining book to reduce the risk of business loss from unsafe practices; households with multigenerational users, ranging from incautious tee...

10 PRINT CHR$ (Software Studies)
by Nick Montfort John Bell Ian Bogost Patsy Baudoin Jeremy DouglassA single line of code offers a way to understand the cultural context of computing.This book takes a single line of code—the extremely concise BASIC program for the Commodore 64 inscribed in the title—and uses it as a lens through which to consider the phenomenon of creative computing and the way computer programs exist in culture. The authors of this collaboratively written book treat code not as merely functional but as a text—in the case of 10 PRINT, a text that appeared in many different printed sources—that yields a story about its making, its purpose, its assumptions, and more. They consider randomness and regularity in computing and art, the maze in culture, the popular BASIC programming language, and the highly influential Commodore 64 computer.

100 Things We've Lost to the Internet
by Pamela PaulThe acclaimed editor of The New York Times Book Review takes readers on a nostalgic tour of the pre-Internet age, offering powerful insights into both the profound and the seemingly trivial things we've lost.Remember all those ingrained habits, cherished ideas, beloved objects, and stubborn preferences from the pre-Internet age? They&’re gone.To some of those things we can say good riddance. But many we miss terribly. Whatever our emotional response to this departed realm, we are faced with the fact that nearly every aspect of modern life now takes place in filtered, isolated corners of cyberspace—a space that has slowly subsumed our physical habitats, replacing or transforming the office, our local library, a favorite bar, the movie theater, and the coffee shop where people met one another&’s gaze from across the room. Even as we&’ve gained the ability to gather without leaving our house, many of the fundamentally human experiences that have sustained us have disappeared.In one hundred glimpses of that pre-Internet world, Pamela Paul, editor of The New York Times Book Review, presents a captivating record, enlivened with illustrations, of the world before cyberspace—from voicemails to blind dates to punctuation to civility. There are the small losses: postcards, the blessings of an adolescence largely spared of documentation, the Rolodex, and the genuine surprises at high school reunions. But there are larger repercussions, too: weaker memories, the inability to entertain oneself, and the utter demolition of privacy.100 Things We&’ve Lost to the Internet is at once an evocative swan song for a disappearing era and, perhaps, a guide to reclaiming just a little bit more of the world IRL.
