upstart writes in with a story, submitted via IRC, for SoyCow9427 that was the inspiration for:The BBC has posted a story, The mysterious origins of an uncrackable video game, which describes the investigation by two Game Archaeologists into the Atari 2600 game "Entombed".The article is a narration of the story outlined in the abstract: Entombed: An archaeological examination of an Atari 2600 game (DOI: https://doi.org/10.22152/programming-journal.org/2019/3/4) and full article (pdf):The Atari 2600 was an extremely limited device with 128 bytes of RAM, a scaled down version of the venerable 6502 processor called the 6507 which had only 13 address liness restricting it to 8 kB of addressable memory, no interrupt processing, and it had no frame buffer, so each line of pixels to be displayed had to be calculated in real time — racing the beam — so being limited to exactly 76 machine cycles per line. The paper succinctly puts it: "Given that 6507 instructions all take two or more cycles, there was no room for inefficiency."As if that were not enough of a challenge, there were no libraries in ROM, all code had to be hand-crafted. No programmer documentation meant that to even get started programming, one had to reverse engineer how the 2600 even worked.The word "uncrackable" in the title is not of the crypto flavor one would normally assume, but instead of the "How did they come up with that?" variety. Specifically: create a scrolling maze that had a path through it, all with the aforementioned hardware limitations.Read more of this story at SoylentNews.

chewbacon writes:Engadget and others are reporting that contrary to the very spirit of the set-top box DVR, TiVo says all subscribers with select devices will see ads prior to playing recorded shows after a software update rolls out. TiVo says subscribers will be able to skip the ads coming in the next 90 days, but did not elaborate on this as a user says they had to fast forward through the ads. Many subscribers are angry and threatening to cancel, calling the ads a feature that devalues the service as they pay for the ability to skip ads altogether.This prompts the question: will cable companies, losing subscribers and looking to replace that revenue, do the same with their DVRs?Original article: https://www.engadget.com/2019/09/21/tivo-pre-roll-dvr-ads-for-all-users/.Original SubmissionRead more of this story at SoylentNews.

SemperOSS writes:At the All Systems Go conference in Berlin 20-22 September, Lennart Poettering proposed a new extension to systemd, systemd-homed.service. A video of his session can be downloaded from media.ccc.de with accompanying slides [PDF].In his presentation, Poettering outlines a number of problems he sees with the current system, like /etc needs to be writeable, UIDs need to be consistent across systems, and lack of encryption and resource management.His goals with the proposed solution are migrateable and self-contained, UID-independent home directories with extensible user records that unify the user's password and encryption key; LUKS locking on system suspend; and Yubikey support.He identifies a number of problems this new idea could cause with SSH logins, disk space assignments, UID assignments, and LUKS locking.He plans to introduce JSON user records that can be queried via a Varlink interface and to a certain extent are convertible to and from existing formats. The home directories will be stored as LUKS-encrypted files that will be managed by the proposed new service, systemd-homed.service. The system integration will be supported by pam_systemd and systemd-logind.service.It will be interesting to see how the world responds to this new take on systemd's ever-increasing encroachment of Linux.... and lastly, this story is brought to you from a systemd-free laptop.Original SubmissionRead more of this story at SoylentNews.
