About borski

Just a hacker in the SF bay area who likes technology of all sorts; cyber security expert, founder, angel, advisor/mentor, and singer/musician. :)

Working on https://www.kobofoundry.com

I have always been more interested in why and how things worked, rather than just being content that they did.

20+ years in offensive software security, eight patents (I hate them but tell that to the VCs who love them)

Sold Tinfoil Security, after 9 years of building it, to Synopsys, in January 2020. Hell of a ride.

My (last) startup: https://www.tinfoilsecurity.com acquired by https://www.synopsys.com

Twitter: @borski

borski@owlpost.lol -- get in touch! I'm always up for meeting interesting people.

    Given that most dogs are adopted from shelters, dog behavior is often a reflection of early upbringing. The current owner can train and teach their dog, but some behaviors and fear…

    Do you have anything to indicate this? A source or any analysis?

    They often have promotions which can make this very lucrative. “spend at least 1 mile, get 40% off” etc

    I’m familiar with the margins in retail (my parents ran a retail store their entire lives). My point wasn’t that they don’t do a lot of volume; it’s that their retail business is n…

    True, but at higher prices (and with delivery fees), which somewhat defeats the purpose of the cost savings at Costco.

    In Q1 2026, AWS was 60% (roughly) of Amazon’s operating income. I’m not so sure their retail piece is the part that’s making them big money.

    David Sacks could not be further from a reliable or impartial narrator on this topic. And before someone calls this an ad hominem, it isn’t; I am not saying he is bad or morally wr…

    Yes, and if you’re driving late at night near a college campus I’d recommend slowing down and being extra careful. College kids are allowed to get drunk and act stupid. You are sti…

    Out of how many pedestrian-vehicle collisions? Anyway, I am not saying it never happens.

    I agree, of course. That is far from the most common scenario. In the most common scenario, it is the driver’s fault. Of course there are exceptions to everything.

    It is either a YC company or the poster was (or is) a YC founder.

    If you walk around yielding a knife, and you accidentally walk into someone who wasn’t paying attention, it is definitely your fault. If you drive a car and accidentally drive into…

    The pedestrian is not the one driving the weapon. It is your fault if you hit a pedestrian, even if they walk right off the curb, even if they’re drunk. Unless they intentionally j…

    > I'm doing no such thing. By invalidating the Monet piece if it is described as AI-generated, art becomes entirely about the creation story. So that moves the bar to telling a con…

    You misunderstand art. If art were solely about the outcome, we’d all be staring at photographs instead, as no art will ever have as high fidelity. Art is about the journey of the …

    That was just as true a decade ago, and two decades ago, as it is today. Bad “software engineers” have always existed. That hasn’t changed.

    It does, in the higher echelons of performance / seniority. Junior wages won’t change, and may even get lower. But, at least at present, the top devs are earning more than ever as …

    Not any efforts. But this one is certainly allowed to be a dumb effort, if it is. Not all things that are called “ethical” or “safety” are worth doing.

    Getting excited about the announcement of new capabilities is very normal. People used to wait in line all night to buy an iPhone. This isn’t that different.
