#\s+ is:

• #: a literal #
• \s: any whitespace character (space, tab etc)
• +: the previous thing (here the whitespace), one or more times

In words: "a hash followed by at least one whitespace character"

#[^\s]. is:

• #: a literal #
• [^\s] : a negated character class. This matches anything other than the set of characters after the ^. \s has the same meaning as before, any whitespace character
• . : matches any single character

In words: "a hash followed by any character other than a whitespace character, then any character".

https://source.android.com/docs/setup/contribute/licenses says most of the Android userspace is Apache 2 licensed. While they can't close source the Android branch of the kernel, they could close-source new userspace code and it would probably diverge from the last open source release quite quickly.

Realistically, that would probably be sufficent to make Android functionally closed-source, even if the GPL bits were still available.

And they're not going to pay millions to be the default for a browser that no one uses.

Yeah, its not unreasonable that you'd have a remote way to access the device to gather debug data with the customers consent. An SSH key in the firmware is a flexible way to do that, so long as there are good controls in place to ensure that it isn't misused.

I think multiple people already have access to the databases that store the data the device sends. I don't really care whether they get the data from the device itself or from the database.

Similarly, I think multiple people have the ability to make changes to the firmware build and the systems that distribute it. So those people already have the potential ability to gain access to the device.

One person or multiple people having unauthorised access are both unacceptable. I'm saying that the users have to trust the companies ability to prevent that occurring, and that therefore this particular technical detail is mostly irrelevant

I'm 90% sure it is not a single user. I just don't see how that really affects the security of the product, given that the company that sells it can already do the things the author is saying can be done if you have this key.

To be clear, I wouldn't buy this. I just don't think the SSH key makes it any worse than it already was

A shared account doesn't mean everyone who works there has access to it, or that those who do have access aren't subject to some type of access control.

The article basically goes on to say that the existence of this key makes a huge difference to the security/privacy of the product. It argues that using it, someone could access data from the device, or use it to upload arbitrary code to the device for it to run. However, those are both things the user is already trusting the company with. They have to trust that the company has access controls/policies to prevent individual rogue employees doing the things described. It seems unreasonable to say that an SSH key being on the device demonstrates that those controls aren't in place.

The email address attached to the public key, [email protected], to me suggests the private key is likely accessible to the entire engineering team.

This assumption is doing a lot of heavy lifting in the authors argument that this is a big deal.

This assumes that the reviewer who gave the rating wasn't considering value as part of their scoring. I'd expect the reviewer to be scoring a TV based on his good it is compared to similarly priced competitors, not comparing to every other TV on the market

Sure, but then you've just shifted the problem up a level. Now I have to trust that the user id you provide me in the insecure channel really is you. Which means either trusting the insecure channel or trusting that the web app has confirmed who you are in some other way before giving you an ID.

We have to reject the first since we could skip all the asymmetric crypt and just send a symmetric key directly in the insecure channel.

If we're trusting the web app has confirmed your identity, we've moved from "just quickly go to this page and it'll generate you a public key" to "go to this site, upload a photo of your ID and a video of you saying that its you and whatever other verification is needed, then it'll give you a public key".

You originally wrote:

The one sticking point is that your recipient needs to visit the site before you can send your vacation photos to them, but is it really that hard?

The hard part isn't them going to the site in advance, it's them establishing trust with the site that they are who they claim to be.

Even if you're using asymmetric cryptography, you still have to trust the insecure channel. If an attacker can replace the URL sent there with their own then they can have the sender encrypt the files with an attacker controlled public key rather than the legitimate one

It's not that you change the passwords for each website often, it's that you use a different password for each site. That way if one site gets hacked and your password is leaked, it can't be used to access your accounts on other sites.

Plenty of costs don't depend on how much usage there is. If a tree falls and takes out a power line it cosrs the same whether that line was being used at 1% capacity or 100%

It's a quite entitled view to take that they should make an effort to pass the project on. It would be very hard to build sufficient trust in a new developer quickly, and passing it on without that trust would be undermining the trust that users of the projects have placed in this dev. If I were him, I wouldn't be staking my reputation on finding someone to take over from me if there wasn't already an obvious candidate.

The successful fundraiser you mention looks to have had a target of $12k USD (from: https://discuss.techlore.tech/t/divestos-is-unsustainable-needs-community-support-we-sent-250-and-you-can-help-too/6660, the original page has been taken down), and was as a alternative to them taking a full time job. I'd say its a reasonable bet that money was spent on living expenses, and IMO $12k a year is much less than this level of skilled work is worth. It's certainly not enough money to make it unreasonable to shut down the project a year later, and I doubt anyone who donated feels shortchanged by it.

Why would it need 5GHz? At most it needs to do two audio streams, which aren't going to need lots of bandwidth

The upside of IANA doing it would be a standardised place for sites to move to. Without coordination, different sites would move to different TLDs, probably mostly based on what isn't already registered. IANA could create a new TLD for this and give existing whatever.io owners a chance to register whatever.iox before its generally available

If you're just commuting & riding flat, even-ish trails, you maybe don't need a MTB at all. You'll get much bigger changes in handling/comfort/speed from changing the style of bike than the marginal gains from upgrading individual parts.

What are you hoping to gain from a drivetrain upgrade? It might make more sense to look at changing the type of bike you have, rather than trying to transform a MTB to act like a hybrid/gravel/road bike

How exactly is it hashed? There aren't that many possible phone numbers, so it might be viable to just try every valid number until you find one that matches

Blaming Spotify for this is like blaming the company that made your TV for showing you ads that are part of the broadcast. Unless Spotify makes the specific podcast you're listening to, they're just playing you the content someone else made, including the ads they included in that content.
