  • Messaging, web browser, podcasts, navigation, a couple services that require a phone to access. I tend to not install apps that could be websites.

    Hardware drivers are surely dated. Android, on the other hand is 15, and I assume getting updated to 16 soon. I think I’m pretty good with regard to the sort of zero-click exploits I’ve heard of used for targeted attacks. If somebody slipped a trojan into a software update, I could have a problem, especially if it was a privileged app like AccA or Adaway. Of course, updated drivers wouldn’t protect me from that.


  • The entire smartphone industry.

    I use five year old smartphone (Pixel 4a). I can afford a new one, but I don’t need a new one, and it would be worse in ways I care about (bigger, probably without a headphone jack), without being better in any way that really matters to me, so I don’t want a new one.

    Official software updates ended a couple years ago, but I’m running LineageOS and I got an update this week. Google has intentionally made it hard for most people to use LineageOS or any other Android distribution not blessed by Google as their primary phone by allowing app developers to check whether it’s Google-approved. For now, I can usually work around that, but it would be too big a hurdle for most people.

    The kernel is getting pretty old though; it’s 4.14 when I’m up to 6.17 on my laptop. This is because SOC vendors don’t release open source drivers, nor maintain the proprietary ones for very long.

    Finally, there’s the battery. Mine is in great shape because I use AccA to limit charge to 60% most of the time, but charging to 100% as most people do would have greatly reduced its capacity by this point. Replacing it requires melting glue and some risk of damage. Most phones are like that now (though that’s changing due to EU regulation).





  • The article doesn’t talk about the fact that the increase is far greater in dark conditions, which is not readily explained by the changes to car design the article discusses.

    This article talks more about that, and the linked report suggests population trends have contributed to more people walking at night along arterial roads with poor pedestrian infrastructure.

    To be clear, daytime fatalities are up by about 40% in the interval shown, which is much more than the increase in population. Increasing vehicle size and hood height are real problems too, but don’t seem to be the biggest factor.




  • I’m scared.

    Of what? This is not a rhetorical question. Security starts with threat modeling, and your threat model dictates the precautions you need to take.

    If you’re most people, your main privacy threat is advertisers and data brokers. Other comments have detailed how they collect data, and it’s usually “voluntary”. Defenses against this include a browser with good adblocking like Firefox with uBlock Origin, using websites instead of native apps as much as practical, using DNS-based adblocking, limiting or eliminating use of corporate social media, turning off voice-activated assistants, and preferring open source when practical.

    It is not likely that advertising companies are activating the microphone or camera on your phone without your knowledge. The legal penalties for doing something like that in most countries would be ruinous for even the largest corporations, and the motivation for security researchers to check for things like that is substantial. If it did happen, the impact on your life would likely be a small payment from the resulting class-action lawsuit several years later.

    If you live under a repressive regime that is known to routinely install spyware on phones, you may have different concerns. If an intelligence agency, large criminal organization, or multinational corporation is directly targeting you and willing to spend more money than most people have surveilling you, they’ll probably succeed even if you throw your phone in the ocean.


  • In any case, modern Android phones and modern iPhones do display an indicator when an app (or the system) is accessing your microphone. I do not know if this can be disabled.

    It can’t, for certain values of can’t.

    On Google certified Android, the feature is required; apps cannot disable it, and there isn’t a UI toggle for it. A phone manufacturer who added a way to disable it would be breaking its contract with Google and could owe money or lose the ability to ship Google certified Android. As for Google’s own devices, “just trust us”. If you have a normal threat model, that’s probably good enough.

    If someone very sophisticated and resourceful is targeting you directly, that may not be good enough. It can be disabled with ADB, and it’s possible to run ADB commands on-device. It would be hard to make that happen without physical access to your unlocked phone, but if your adversary is sophisticated enough and the stakes are high enough, it would be unwise to rule it out.


  • Sony once sold a video camera that could sort of do that under specific circumstances.

    Cameras usually have a filter to block infrared light, but that camera offered the ability to toggle the filter to improve the camera’s performance in low light. Hobbyists also sometimes modify cameras to remove their infrared filters for artistic effect or to photograph animals at night without disturbing them with visible light. Some clothing is not fully opaque to infrared light, so an IR camera can sometimes capture some detail of what’s underneath. Adding a filter that reduces visible light and passes IR might increase the effect.




  • I don’t especially want to be in the position of defending either spez or r/jailbait, but I was on Reddit at the time and I do think I should explain how 2008 was a different time on the web.

    There had been a number of attempts to censor and age-gate the internet in the late 1990s and early 2000s. People involved in creating internet tech and building its culture were almost universally against anything that even smelled like censorship. Much of the early userbase migrated from Digg in response to Digg censoring a leaked DRM key. The only sitewide rule on Reddit was “don’t break Reddit”.

    When r/jailbait finally did get banned in 2011 and Reddit’s first content policy was imposed, that decision was unpopular among Redditors even though most thought sexualizing young teenagers was disgusting. It signaled a change to what Reddit was, and people rightly feared that it would lead to significantly more restrictions. Now I have to enforce a rule on r/flashlight that people can’t sell flashlights designed to be attached to guns, and I don’t want to make or enforce such a rule.





  • The reason cast iron is useful for searing a big cut of meat is that it has a reasonably high specific heat capacity (less than aluminum, more than copper, similar to steel) combined with considerably more mass than typical cookware made of other materials. It takes longer for the meat to cool the pan, so more heat transfers into the outer surface of the meat.

    Cleanup of properly seasoned cast iron should be about as easy as non-stick pans because the seasoning (polymerized cooking oil) is, in fact a non-stick surface. Contrary to popular belief, it’s fine to use soap on it, but aggressive abrasives can strip the seasoning. Fortunately, that’s not hard to fix.
