  • Don’t even need that. Meta crosses multiple platforms now - Instagram, FB, WhatsApp, etc. All you need is for someone you know to have you in their contacts list, and the hit the “allow access” a single time. All of that data is then scraped, cataloged, and cross referenced with everyone else. Name, address, phone numbers, birthday, work address - anything your contact felt it convenient to add about you in their phone. From there it’s just a matter of time until data mining of second and third level contact - or outright data leaks - fill in the rest of your profile and demographic information.





  • I think it doesn’t go far enough. Straight up, no one should be permitted to create or transmit the likeness of anyone [prior to, say, 20 years following their death] without their explicit, written permission. Make the fine $1,000,000 or 10% of the offender’s net worth, whichever is greater; same penalty and corporate revocation for any corporation involved. Everyone involved from the prompt writer to the work-for-hire people should be liable for the full penalty. I can’t think of a valid, non-entertainment (parody/humor), reason for non-consensual impersonation - and using it for humor or parody is a slippery slope to propaganda weaponization. There is no baby in this tub of bathwater.





  • Interesting that I learned 32.2 ft/s, but only 9.8 m/s - one less significant figure, but only a factor of two in precision (32.2 vs 32 = .6%; 9.81 vs 9.8 is only 0.1%). Here’s the fun part - as a practicing engineer for three decades, both in aerospace and in industry, it’s exceedingly rare that precision of 0.1% will lead to a better result. Now, people doing physics and high-accuracy detection based on physical parameters really do use that kind of precision and it matters. But for almost every physical object and mechanism in ordinary life, refining to better than 1% is almost always wasted effort.

    Being off by 10/9.81x is usually less than the amount that non-modeled conditions will affect the design of a component. Thermal changes, bolt tensions, humidity, temperature, material imperfections, and input variance all conspire to invalidate my careful calculations. Finding the answer to 4 decimal places is nice, but being about to get an answer within 5% or so in your head, quickly, and on site where a solution is needed quickly makes you look like a genius.


  • Yeah, that’s just a shitty (or out of spec) time base. My Seiko watch gains 1-2 minutes a day, but it’s completely mechanical so it depends on temperature and winding/mechanism tension for accuracy. There are electronic timing circuits which are resistance and capacity based, and as the resistance and capacitance of the system drift (time/age and temperature) they also drift. A crystal, made to vibrate at high frequency (piezoelectrically, iirc), will provide a much more stable time base and be accurate to seconds over many days’ time.

    Interesting aside - time keeping is how ships at sea used to determine where they were in the ocean. Latitude can be found from the stars, but longitude can’t so it needs a time reference standard. The book, Longitude tells the story of the search and the competing methods for determining location prior to the invention of crystal/electronic time bases and modern GPS. I won’t say that the storytelling is particularly gripping, but the actual path to discovery is fascinating.


  • That’s probably just fluctuations in the line frequency and the method for keeping time varying between the two (one might use a crystal that drifts). Being on the “wrong” frequency will have it shift by hours every day. I had a (US/60Hz origin) microwave in my apartment in Bonaire (50Hz) last year that never seemed to have the right time, and when I did the math I realized it was the frequency - it was behind by ~4 extra hours every day (50/60 x 24 hours).




  • SMS and (at least for craigslist) voice 2FA doesn’t work with VoIP (Google Voice numbers, including numbers ported from mobile operators). IRS 2FA via SMS definitely doesn’t work, nor does Dunkin Donuts (which invalidates use of their entire app on all mobile platforms). Some services offer voice 2FA which will go through, and some offer email, but many don’t. Of course the vast majority of 2FA over SMS work with the major VoIP providers, but if you hit one where it doesn’t…there’s either no way around it or you have to wait for a snailmail 2FA token (IRS).


  • I currently have (almost) only VoIP numbers. My cell phone technically has a carrier number, but only my immediate family and two friends (8 people in total) actually have that number for my contact, and I keep it that way for safety/security purposes. As a result, I already can’t do things like try ChatGPT, use the some vendor apps, or get quasi-2 factor codes from several businesses - including the IRS. Their systems simply can’t interact across a VoIP gateway. There really should be a certificate authority for these things, but the POTS system is just so fucking old.




  • Storage and transport of H2 is a big deal because of the unique properties (very low transition temp/very high pressure for liquid). That generally means for a non-pressurized, non-cryogenic storage it has to be combined into another molecule and then catalyzed back out, real time, for use. And, of course, the ignition ratio range (4%-75% in air) means that it’s very easy to accidentally ignite a H2 leak; substantially easier than most other fuels, though this is mitigated by it’s density and ability to disperse in an unenclosed area.

    Production is theoretically energy efficient as you can create it with hydrolysis, but the cheapest way of producing it, by far, is cracking of methane, which requires a high temperature process to create. It may not produce a high volume of CO2, but it perpetuates the cycle of exploration and extraction of gaseous hydrocarbons and the related environmental dangers and downsides.


  • Sorry, in advance, for the long, descriptive post, but the value of a dedicate, slide mute switch is somewhat nuanced.

    The mute switch on an iPhone is a physical slide switch. Without looking, you can feel if it’s muted (back) or active (front) position. Alternately, you can see the condition as, when it’s in the “mute” position, it has an exposed orange (painted) indicator. Neither of these verifications require that the phone be awake or to light up the screen. It can also be activated with the device off, so that if you turn the phone on in a quiet place you don’t have to wait for the UI to become responsive (usually after start notifications have actuated, which occur before software buttons can be pressed to mute the phone). It is a single action to mute, compared to a 5 gesture sequence to silence the phones primary sounds (which can be ringtone OR playback volume, but not both) and an 6-8 gesture sequence (depending on the wake-status of the last used app) to silence the secondary phone sound. Note: I’m assuming that face unlock is active and you are staring at your phone obtrusively; entry of the unlock code would add 7-9 additional touch gestures.

    While I agree that a button is nice, it still takes at least two actions - press the button and visually confirm its actuation puts it into the desired mode. There are times when you are unsure what mode the phone is in. On an iPhone, that is not visible from any screen until you either a) wake the phone and actuate a volume button (neither visual nor haptic feedback occurs when a volume button is pressed) or are logged into the phone (two minimum gestures plus face authorization) and use the action center (swipe function) to visually verify th volume position.

    Now, you could easily argue that this is fucking terrible UI design, and I would 100% agree with you. I would, likewise agree, that most technical features on an iPhone are certifiably obtuse - ex: you cannot turn on your hotspot without entering the settings app; it’s not even an action center icon option as it is on Android. I would add that it’s also monumental dumbfuckery that your hotspot is the name of your phone and cannot be changed. Or that there is no function to alter the Prompt volume in the phone (ie. for GPS directions) unless the prompt audio is actively playing - difficult if the prompt volume is accidentally (or temporarily) set to zero. In 3rd party apps the prompt volume is several menus deep; for the OEM map application, it doesn’t exist - there is literally no setting.

    But, it remains - if you want to mute the alerts on your phone, the switch requires fewer actions and zero view of the device to actuate, and zero activation of the screen or login to verify it’s condition. You may never need to discretely silence your phone or check that it is in silent mode without taking the phone out and unlocking it, but many of us find it quite useful.
