Is it better to use a non-FOSS email and phone number forwarder or to use one of each for everything? (www.cloaked.app)

I like to try websites out before tying my identity to them. How do you do it? Simplelogin? I honestly won’t manually make a new gmail for every new website I try and I to want the option to see what emails I get.

systemd-boot discovers windows automatically, no need for configuration.

Detecting extensions using web accessible resources is not possible on Firefox as Firefox extension ID’s are unique for every browser instance. Therefore the URL of the extension resources cannot be known by third parties.

and also for Chrome:

in manifest v3 extensions will be able to enable ‘use_dynamic_url’ option, which will change the resource URL for each session (browser restart). This will render this detection method unusable.

Though it should be noted that this method isn’t the only way to detect extensions.

The way it’s written doesn’t say whether it simply isn’t made to work for Firefox or whether it couldn’t be made to work for Firefox. Fortunately, the latter appears to be the case.

Testing packaging which targets multiple distributions?

I am working on creating deb/rpm packages for an OSS tool I use. So far, I have been manually testing each deb/rpm in a virtualbox live cd version of that OS but it’s tedious to do that for every release. This is a GUI tool, I basically just need to confirm that the apt install goes correctly and the program can actually...

This kind of integration testing is best left up to the individual distros. Same as the integration (as in: packaging) itself.

Distros don’t want your binary package, they want your source code, build instructions and a build system that won’t make them cry. Some distros even explicitly disallow re-packaging external binary distributions.

As a distro maintainer, I appreciate your wish to do QA on all the distros but that’s just too much work. You focus on making your software better, we focus on making it work with the rest of the software ecosystem.

Providing a package for one or two distros (i.e. your favourite one) is good practice to ensure your software can be reasonably packaged but it’s not the primary way your users should receive your package in the traditional Linux distro model.
Additionally, you might want to package your software for one of the cross-distro package managers such as Flatpak, AppImage, Snap, Nix, Guix, distri or homebrew. This can serve distro maintainers as a point of reference; showing how it is intended to work so they can compare their packaging effort. If there’s some bug present in the distro package but not the cross-distro package, that’s a good sign the issue lies in the distro packaging for example.
Again, don’t put much time in this. Focus on your app.

I use NixOS but I don’t bother with automatic deployment or even automatic formatting. I don’t feel it’s necessary in a homelab setting as hardware failure rarely happens at such small scale and the manual steps left aren’t that significant.

Proton Mail CEO Calls New Address Verification Feature 'Blockchain in a Very Pure Form' (tech.slashdot.org)

Proton Mail, the leading privacy-focused email service, is making its first foray into blockchain technology with Key Transparency, which will allow users to verify email addresses. From a report: In an interview with Fortune, CEO and founder Andy Yen made clear that although the new feature uses blockchain, the key technology...

Voting is another concept that would become unhackable overnight

No. Voting on the blockchain is an even worse idea than money on the blockchain.

In many cases, there are good reasons why these things are done they way they are. I have yet to see a software system that is better at preventing voter fraud than humans looking at your government-issued ID at a poll site and humans overseeing other humans manually counting votes.

A single actor might be able to commit voter fraud in the order of dozes or hundreds of votes perhaps but with a digital voting system based on blockchain, they could do so on the order of thousands or even millions by compromising end-user devices used for voting or buy enough work/stake/whatever to perform a 51% attack.

Same goes for money btw. Our current system is by far not a perfect one but removing the ability for governments to i.e. freeze accounts of bad actors is not a boon.

nobody’s made a solution that is simple and effective

This one isn’t that either by the looks of it but it’s certainly a problem where something like blockchain could provide a solution.

This is false. Protonmail has supported Web Key Discovery for external domains since 2019: proton.me/blog/security-updates-2019

Atemu,
@Atemu@lemmy.ml avatar

So PM claims it has on the order of 10^8 users. Let’s assume each user has one email address with one public ed25519 key, both of which are likely false.

Each key is 32Byte; 32B * 10^8 = 3.2GB.

Could someone do the math how much fiat it’d take to store such an enormous amount of data on the Ethereum or monero blockchains?

Homomorphic encryption enables votes to be both public and obfuscated at the same time.

That’s nice but has nothing to do with voter fraud prevention.

I will not reply to the stupid ad hominem. You have made it exceptionally clear that you have no idea what my political views are.

Understanding init freedom?

I’m planning to move over to Guix over NixOS, as soon as my current situation improves and possibly import a new libre respecting laptop (Star Labs is thankfully available in India). I do have a very old laptop with a Celeron processor and 4GB of RAM with Guix installed already, and what has come to my attention is that it...

It actually is. The file gets opened by bash and bash passes the file descriptor to cat but cat is the program which instructs the kernel to write to the device.

Modern cat even does reflink copies on supported filesystems.

systemd has become like the JavaScript of init systems

Likening systemd to JavaScript is incredibly inappropriate.

systemd now handles DNS, cron, bootloader, and is a suite of tools tightly coupled with the init system)

No. Except for the cron replacement, all of those are stand-alone tools that can be run with systemd, without systemd or replaced with any alternative.

They just happen to be developed under the systemd project umbrella and are obviously tested to work well with another.

This argument is especially weird for systemd-boot; it’s not even a Linux program ffs.

There are some components that are harder to replace with alternatives but mostly because no good alternatives exist. Systemd might be partially to blame here in how easy it is those parts can be ran independently and replaced with equals and you could certainly criticize it for that but you didn’t even mention one of them.

Truth be told, the birth of systemd really heralded in the death of the UNIX philosophy

There is no truth in this sentence.

Doing one thing only, and doing it well, while looking good on paper, and oftentimes is a good general rule of thumb, doesn’t apply to modern application development, for better and worse.

What? Please google “Microservices”.

Your whole wall of text hinges on the assumption that systemd is a simple “init system”; a root process spawning a set of other processes. This is false.

systemd (as in: PID1) does service management, not init. It happens to also fit into the “job description” of init because starting and cleaning up dead services also fall under the responsibility of a service manager but reducing it to just an init system is just plain wrong. All the other things are handled by separate components/processes.

Thus, it still follows the “unix philosophy”. The “one thing” it does simply isn’t what you think it does.

It’s like saying cp doesn’t follow the UNIX philosophy because you could copy files with cat. cat is soo much simpler to understand, why would anyone ever use the bloated cp? Must be the pesky commercial influence of Bell labs!

Truth be told, the birth of cp really heralded in the death of the UNIX philosophy.

simple_cat which does a simple read/write loop

You just proved my own point. cat does the write(). Bash just configures where it writes to.

re the reflink thing, you were probably thinking of cp, not cat.

No, I was specifically thinking of cat. I just copied a 73G non-sparse incompressible file in 3 seconds using cat file > copy.

copy_file_range does reflinks on btrfs.

except for hdds without cache

The “cache” on HDDs is extremely tiny. Maybe a few seconds worth of sequential access at max. It does not exist to cache significant amounts of data for much longer than that.

At the sizes at which bcache is used, you could permanently hold almost all of your performance-critical data on flash storage while having enough space for tonnes of performance-uncritical data; all in the same storage “package”.

Atemu,

Note that bcache and bcachefs are different things. The latter is extremely new and not ready for “production” yet. This post is about bcache.

AMD platform support is coming to coreboot in the next few years, consumer platforms much later and even there I’m doubtful it’d come to your laptop in particular.

Get a Frame.work with Intel chip if you want coreboot on a modern laptop soon-ish. I know the guy working on that port ;)

What you’re doing is perfectly fine.

It is however more of a mitigation for bad distro installers than general good practice. If the distro installers preserved /home, you could keep it all in one partition. Because such “bad” distro installers still exist, it is good practice if you know that you might install such a distro.

If you were installing “manually” and had full control over this, I’d advocate for a single partition because it simplifies storage. Especially with the likes of btrfs you can have multiple storage locations inside one partition with decent separation between them.
