- Comment on Endangered classic Mac plastic color returns as 3D-printer filament 5 hours ago:
They didn’t make it out of brominated ABS, so it won’t turn yellow with age though.
- Comment on True Wireless Power is FINALLY here (building a TRULY wire-free desk setup) 9 hours ago:
FCC emission requirements are very lax below 30MHz, so something can pass FCC part 15 yet still jam the entire HF band.
- Comment on True Wireless Power is FINALLY here (building a TRULY wire-free desk setup) 1 day ago:
Wireless power sounds like and RFI nightmare. It will never match the efficiency of a cable either.
- Comment on Meta and Yandex are de-anonymizing Android users’ web browsing identifiers 1 day ago:
It looks like Meta or Yandex apps must be installed for the exploit to work. Luckily I don’t have any of those installed on my Android devices.
- Comment on In North Korea, your phone secretly takes screenshots every 5 minutes for government surveillance 2 days ago:
They can’t see much through the electrical tape over the lens.
- Comment on The plan for nationwide fiber internet might be upended for Starlink 6 days ago:
Every single time the land line ISPs have gotten money for rural broadband, they use it for something else and don’t build anything. Starlink actually built a network that works. Many places have gotten decent 5G home internet too.
I have been promised fiber for over a decade yet the only wired connection available is a DSL network that’s been so poorly maintained that it barely even functions.
- Comment on ISPs seem designed to funnel people to capitalist cloud services 6 days ago:
My dynamic IPv6 prefix hasn’t changed in a couple of years. It only changed because I reset the router config and that changed my DUID. That’s good enough for everything I host. I don’t even bother with dynamic DNS anymore.
I wouldn’t bother with trying to host an email server from a residential connection though. Even if you can get your ISP to open port 25 for you, many email servers won’t accept mail from residential IP addresses.
- Comment on IPv6 for self hosters 6 days ago:
If you need IPv6, you can get a free tunnel from Hurricane Electric. They will give you a /48 if you request it. I used it for years since my old ISP didn’t have IPv6. I am close to one of their servers, so the latency was very low.
- Comment on The sun is killing off SpaceX's Starlink satellites 1 week ago:
During solar maximum, the lifetime of a satellite could be reduced by up to 10 days, the researchers say.
I’m sure they have, but it doesn’t make a significant difference. The headline is just clickbait.
- Comment on Is it OK to leave device chargers plugged in all the time? An expert explains 1 week ago:
I unplug the switching power supplies when I’m not using them because I don’t want to listen to the RFI that they produce.
- Comment on Is it OK to leave device chargers plugged in all the time? An expert explains 1 week ago:
Electrolytic capacitors wear out due to age whether they are used or not. Heat makes them wear out significantly faster. If the power supply is not under load, it shouldn’t be producing any noticeable amount of heat.
- Comment on Prototype of RTX 5090 Appears With Four 16-Pin Power Connectors, Capable of Delivering 2,400W 1 week ago:
They could have just used normal 8 pin connectors in that case.
- Comment on My two cent about emails servers field. Over a two decades... 1 week ago:
Almost every scam email I get comes from a gmail address. If a business is not sending emails from their own domain, I automatically assume it’s a scam.
- Comment on The oldest Fire TV devices are losing Netflix support soon 1 week ago:
You can always use Jellyfin or Kodi with your old Fire TV and get your Netflix shows elsewhere.
- Comment on Realtek's $10 tiny 10GbE network adapter is coming to motherboards later this year 1 week ago:
It is being pushed beyond its ratings, so there’s no guarantees that it will work. There’s no harm in trying Cat5e at higher speeds if it’s already installed, but don’t install it with the intention of using it at more than 2.5G.
- Comment on Realtek's $10 tiny 10GbE network adapter is coming to motherboards later this year 1 week ago:
It’s impressive that they got the power consumption down to less than 2 watts. I think this is the first 10GBASE-T NIC I’ve seen that doesn’t have a heatsink on it.
- Comment on “How you design the beep is important.” Behind the movement for calmer gadgets. 1 week ago:
Heat makes lithium ion batteries fail much quicker. A non rechargeable lithium AA would last a long time and they don’t leak like alkaline batteries.
- Comment on “How you design the beep is important.” Behind the movement for calmer gadgets. 1 week ago:
Gas valves and igniters don’t even need much power. They could put a battery in there so it could be used when the power is out. My propane fireplace runs for years on 4 AA batteries and that’s powering the receiver for the remote too.
- Comment on Russia to enforce location tracking app on all foreigners in Moscow 1 week ago:
Why do they need an app instead of just using cell tower data? I guess you just take a flip phone then.
- Comment on Amazon is sending customers refunds for some really, really old returns 1 week ago:
with one poster claiming to have received almost $1,800 this week for a TV returned to the retailer in 2018.
Wow, I would have filed a charge back and deleted my account if Amazon did that to me.
- Comment on Heat setting magnets is bad. 1 week ago:
The most common grades of neodymium magnets will demagnetize at around 60-80°C. Even if they could handle the temperature, they wouldn’t stay in place well since they are smooth.
Epoxy and super glue both work well for gluing the magnets in a hole. Rough up the back side if the magnet so the glue has something to hold on to though.
- Comment on Stack overflow is almost dead 2 weeks ago:
If they move to Discord, nobody will ever be able to find the answers. They must use a website that is indexable by search engines or it will be pointless.
- Comment on Huawei’s foldable laptop is probably thinner than your phone. 2 weeks ago:
I hate thin laptops. The screens flex when you open them and feel like they are going to break and they don’t have enough connectors.
- Comment on Still booting after all these years: The people stuck using ancient Windows computers 2 weeks ago:
You can get industrial grade CF cards that use SLC memory. They have much better write endurance than normal CF cards.
- Comment on Volvo EX90’s Lidar Sensor Will Fry Your Phone’s Camera 3 weeks ago:
Every normal color camera has an IR filter. If they did not, the photos would be pink in sunlight. Some IR gets though the filter allowing you to see IR LEDs, but it’s significantly attenuated.
- Comment on Volvo EX90’s Lidar Sensor Will Fry Your Phone’s Camera 3 weeks ago:
Cameras have an IR blocking filter and it still damaged the sensor. I don’t know how they can consider it eye safe. I wouldn’t want to be close to one.
- Comment on What are some cool projects that I can do with a 1st gen Raspberry Pi? 3 weeks ago:
It’s got enough power for a retro game emulator.
- Comment on 3 weeks ago:
Finding a charge controller and inverter that’s compatible with the voltage of sodium ion batteries will be difficult.
- Comment on Today’s AI can crack second world war Enigma code ‘in short order’, experts say 4 weeks ago:
What do you expect? Computers have gotten a lot faster over the last 80 or so years.
- Comment on Reddit will tighten verification to keep out human-like AI bots 4 weeks ago:
It most certainly won’t apply to their own bots.
