    …I’m trying to replace my beloved copy of “Gödel, Escher, Bach” and eBay is suggesting the “AA Trucker’s Atlas of Britain” as being “inspired by your recent views” I deeply, deeply hope that there is a subculture of British truckers who are into algorithms & the development of consciousness.

    Remember kids: it’s ok to surveil all the people if less than 1% of them might be really bad people.

  • Tony Blair calls for roll out of digital ID | “…put all your eggs in one basket, it makes it easier to lose them all and for the government to surveil you…”

    2024/12/15 15:51:33 GMT

    Imagine that all your health information was in one place: easy, with your permission, for anyone anywhere in the health service to see. That your passport, driving licence, anything you need to prove your identity, were in one simple digital wallet, unique to you. That you could purchase and pay for any goods or services

    I don’t get much time to read nowadays so I do a lot of audiobooks, and after his Victorian Internet – itself a transformative read – I attacked Tom’s history of the world through drinks: Beer, Wine Spirits, Coffee, Tea & Coca-Cola… and Water makes 7 – and the found the whole content, if not

  • Linux Kernel: TOCTOU in Exec System | …I am sure that there was a vulnerability of this exact kind in Unix circa 1988 +/- 4yrs

    2024/12/09 08:48:00 GMT

There is a Time-of-Check / Time-of-Use issue in the Linux kernel in the exec system calls. The executability permissions are checked at a different time than

  • I remain perpetually amazed how often the same people are one moment calling for “open APIs” and “access to data for research” and the next are “what do you mean you let just anybody scrape the locations of all rental bikes in New York City?”

    2024/12/05 09:55:37 GMT

    This guy scrapes the NYC city bike locations once per minute and has used the data to possibly track a murder suspect; that’s exciting enough but some folk on Bluesky are now panicking about “surveillance” Tell us: which do you want? Open Data or Privacy?
