schestowitz                                        <p>GPS is perfect for navigating roads, because that doesn’t require much precision. But GPS is only accurate to several meters, which means that it is unsuitable for applications that require more precise positioning. GPS RTK (real-time kinematic) systems can achieve much greater accuracy, but they are complex and require a subscription to a correction service. Viktor Kurusa needed accurate positioning for Jul 29 13:40

schestowitz                                        <p>Conciseness is often considered a virtue among hackers and software engineers. FOSS maintainers in particular generally prefer to keep bug reports, questions on mailing lists, discussions in IRC channels, and so on, close to the point and with minimal faff. It’s not considered impolite to skip the formalities — quite the opposite. So: keep your faffery to a minimum. A quick “thanks!” at the end of a Jul 29 13:41
schestowitzdiscussion will generally suffice. And, when someone is being direct with you, don’t interpret it as a slight: simply indulge in the blissful freedom of a discussion absent of faffery.</p>Jul 29 13:41

schestowitz                                            <blockquote>Jul 29 14:16
schestowitz                                                <p>Earlier I described the Plausibly Deniable DataBase (PDDB). It’s a filesystem (like FAT or ext4), combined with plausibly deniable full disk encryption (similar to LUKS or VeraCrypt) in a “batteries included” fashion. Plausible deniability aims to make it difficult to prove “beyond a reasonable doubt” that additional secrets exist on the disk, even in the face of forensic evidence.</p>Jul 29 14:16
