Big-O Complexities / Poster of common algorithms used in Computer Science - ro31337/bigoposter
As functional programmers we always face a dilemma: should we write purely functional code, or sacrifice purity for efficiency and resort to in-place updates? This paper identifies precisely when we can have the best…

<p>What is the metaphor for the computer of the future? The intelligent agent? The television (multimedia)? The 3-D graphics world (virtual reality)? The Star Trek ubiquitous voice computer? The GUI desktop, honed and refined? The machine that magically grants our wishes? The right answer is "none of the above," because all of these concepts share a basic flaw—they make the computer visible.</p>

<p>I cut down the December 2019 RISC-V ISA manual to just the things needed to get started with RV32I, to be even less intimidating.</p> <p>I left out the end of the RV32I chapter with fence, ecall/ebreak, and hints. But included the later page (which many people miss) with the exact binary encodings, and also the chapter with the register API names and standard pseudo-instructions.</p> <p>It's 18 pages in total.</p> <p>I hope it's useful to someone else.</p>

<blockquote> <p>The Portable Document Format, better known as PDF, is one of the most widely used document formats worldwide, and in order to ensure information confidentiality, this file format supports document encryption. In this paper, we analyze PDF encryption and show two novel techniques for breaking the confidentiality of encrypted documents. First, we abuse the PDF feature of partially encrypted documents to wrap the encrypted part of the document within attacker-controlled content and therefore, exfiltrate the plaintext once the document is opened by a legitimate user. Second, we abuse a flaw in the PDF encryption specification to arbitrarily manipulate encrypted content. The only requirement is that a single block of known plaintext is needed, and we show that this is fulfilled by design. Our attacks allow the recovery of the entire plaintext of encrypted documents by using exfiltration channels which are based on standard compliant PDF properties.</p> </blockquote>
