I’m not getting this, at least not yet.

Maybe it’s because I run Pi-hole; I know it filters out a TON of Roku’s telemetry and other traffic. Might be worth setting up Pi-hole on your network and see if stuff like that goes away?

Mozilla’s “least to most creepy” ranking is the best resource I’ve found so far:

I mean, if a car doesn’t see a cyclist until the last moment, swerves to avoid it, and hits something else, the cyclist being there created a dangerous situation for the driver.

Even just considering a driver hitting a cyclist, the driver still has to live with that outcome for the rest of their life. Unless your expectation is that the driver is a psychopath who only cares about the condition of their vehicle, which I suppose is a possibility.

When I had my homelab services exposed to the broader web, I enjoyed using Authelia with NGINX. It supported MFA and worked well enough.

That said, I HIGHLY suggest you expose as few of your home systems to the web as possible. Ideally, I would set up a VPN like WireGuard or OpenVPN and use that to connect into your LAN while on the go.

The more of your home network you expose to the web, the bigger your attack surface. If you can just turn on a VPN that already has strong authentication like asymmetric key pairs, you significantly reduce the ways someone can break into your home network while making as many (or few) of your home services available through that VPN as you want.

Is anyone proposing both?

This feels like a publicity stunt at best. Why de-extinct something at all, especially something with no current ecological niche?

Respectfully, an article from four years ago that I cannot read in full without creating an account, which seems to just reference a calculator from FT that is over a decade old at this point (whose sources I also cannot seem to find) doesn’t impress me. Do you have anything more recent, preferably that sites sources, that you can share? I’m genuinely interested in what data is actually worth

Honest question:

If you feel these tools are essential and there are no other options (not sure I agree, but that seems to be the argument you were making; let me know if I am wrong), what is the alternative?

These things take money to keep the infrastructure running, pay staff, patch security vulnerabilities, and bring new features for those same communities to use. And they are also a public company, which means they have a legal responsibility to return money to shareholders.

I’m not defending Meta, I refuse to use their platforms and will not be buying any of their hardware. But if it takes money to keep the lights on (at a minimum), how does offering ads or a subscription equate to a false choice?

I also feel many don’t understand the full extent, either. They’re used to using fairly secure devices in their everyday life (often not realizing how much the software they install is also spying on them), so why wouldn’t these IoT things also be secure?

In my experience, it’s all very vague and ethereal until the risks are highlighted for them. “So what if Google can read all of my emails? What could they possibly do with that information, anyway; why should I care?” is an example of a portion of a real conversation I’ve had.

The original “clicker” remotes were really neat tech! The way it worked unfortunately limited the number of buttons you could have, but still ingenious.

Do you own another Apple device from which you could remove your phone from your account (instead of using the store’s phone)?

 

I just watched Joe Scotto’s new YouTube video, where he walks you through the basics of setting up KiCAD and designing a simple macro pad PCB. I am actually super excited to use this knowledge to design my own stuff now!

 

Hello!

I've ventured far too deep into the custom ergonomic columnar-staggered mechanical keyboard rabbit-hole, and I think I've finally found myself at my endgame (for now, anyway lol): the Hillside 46.

TL;DR:

Please see "questions" section at the bottom regarding why, how, and if I should use the ESD protection on the right-half, left-half, or both halves of this split ergo-mech keyboard build.

Background:

In constructing this board, I came across a part of the circuit design that has confused my non-expert brain: the ESD chip and decoupling capacitors. At a theory level, I understand that it protects the board from electrostatic discharge (presumably, specifically, the microcontroller) and the damage it can cause. What is weird to me is that this is the only keyboard out of the several split-mech-ergo boards I've built that have featured this protection circuit, and even within the Hillside family of keyboards, the version with 46 keys that I built seems to be the only one with this protection circuit which makes the decision even more perplexing to me.

Given that this is a split-keyboard design with a reversible PCB, there are footprints for the SRV05-4 ESD chip (datasheet here) and decoupling capacitors on both sides of the PCB though they appear to be wired up differently depending on the side of the board you're using (schematic here). On the "top" of the PCB (left side of the keyboard), you would solder the ESD chip with pin 1 at the top-left position. I did this and everything works fine.

On the "bottom" of the PCB (right half of the keyboard), the connections to the pads seem to be mirrored from the "top" of the PCB, but it looks like that was done so in a way that would not allow me to invert the ESD chip, with pin 1 at the bottom-right of the footprint, and still have everything work. I definitely can't keep pin one at the top-left of the footprint on the "bottom" of the PCB, so I'm kind of stuck as to what to do.

Questions:

  1. Are the ESD chip and decoupling capacitors necessary or just nice to have?
  2. If they are necessary or very useful, do I really need them on both halves of the board?
  3. Looking at the Gerber file, it seems like I might be able to mount the ESD chip to the footprint on the underside of the right-side PCB and still have it functional; is that correct?
  4. What is this ESD circuit protecting against, exactly? I assume it's potential voltage spikes on lines that shouldn't have them that can occur if I were to unplug one end of the audio cable while the keyboard was still plugged into power/USB; is that correct?

Thanks in advance!
