Yes, they're serious. The problem isn't that some cars exist, it's car dependency. Car infrastructure is inefficient, expensive and takes up enormous amounts of space. It's also ugly and loud. Cities built around cars get very spread out, so walking, cycling or public transport become inefficient or unsafe options. As a result, you have to drive, whether you want to or not. If you want to go literally anywhere, you have to get into your car and deal with traffic. But it doesn't have to be that way. Cities built around walkability, cycling and public transport are not only more efficient, but also much more pleasant, even for those who still want to or have to drive. Good alternatives to cars are the only way to really improve traffic. The idea isn't to just get rid of all cars but to make it so you don't need one.

is it okay to have a subdomain to connect to vaultwarden?
A lot of the people would disagree but I think so, yes. Provided that you have set up all the security measures such as firewall/fail2ban, you’ll be fine.
Am i better off just trusting bitwarden and sticking with them?
I think of it as a matter of personal preferences. But honestly, if you had to ask this without your own basic plans for security, I’d advice you to stick with Bitwarden. You’ll just sleep better, that’s all.
Sorry, but I sincerely hope you just don’t selfhost Vaultwarden.
Its just a shitty laptop with a slow ass HDD, and who knows how much life its got
I think your main problem is going to be a reliability than security when this is the case. What is your plan for backup? You will be locked out, possibly permanently if you lose Vaultwarden data. Judging by your comments, you really, really don’t want to selfhost password manager of any sort.
Sorry, but I sincerely hope you just don’t selfhost Vaultwarden.
Are you saying this because i dont know much about firewalls and VPNs right now? Or because i dont have a good backup solution? Or something else?
Currently my backup solution might not be the nicest, but im taking regular backups on the same laptop, copying those onto an external HD, and syncing that onto my main PC, hopefully whoch should be enough
Are you saying this because i dont know much about firewalls and VPNs right now? Or because i dont have a good backup solution? Or something else?
Yes.
Backup sounds to be enough but I still advice you not to. You can familiarize yourself with security in general before you do something as critical as a password manager.
Man 100%. If anyone wants to be a computer expert and is struggling, just stick with it and keep learning. You have to learn through experimentation and effort!
It’s just an attitude thing that some people’s egos are hurt when Linux confuses them.
IMO if you are asking such question - stick to Bitwarden cloud.
Passwords, at least to me, is something I don’t want to lose. I don’t trust myself I could provide a proper uptime & security, so I just use cloud version.
Yeah that was something i was worried about too, not like my server is an proper rig. Its just a shitty laptop with a slow ass HDD, and who knows how much life its got
I recently switched to cloud from vaultwarden. I was comfortable enough with the security, but when I started to actually plan disaster recovery, it was something I literally could not afford to get wrong.
So bitwarden is the one service I don’t, and have no plans to, self host.
Bitwarden’s official self hosting stack (not a single container) ships with nightly encrypted database dumps. And their backup page mentions just needing to backup the ‘bwdata’ folder which has worked great for me.
That’s great. For me, at least, getting a server restored from backup on something like aws without access to passwords was going to require more preparation than I was willing to deal with.
Definitely worth exploring if you’re prepared to handle that though.
About accuracy: Analog sensors are more accurate than digital ones and that is because they are analog. While an analog system has unlimited resolution and thus can continuously follow a signal curve, digital systems can only process quantized data and that is a clear disadvantage when it comes to precision. To visualize it, think of analog data as a smooth curve and of digital data as a stair shape that follows the curve. In the picture the red line is an analog signal while the blue line shows how that same signal would look after quantization in a digital system. As you can see the analog red line is an accurate depiction of the actual sensor data while the digital blue line is only an approximation to the original analog signal.
I think parent is referring to quantization in the amplitude/y-axis (bitdepth), whereas you are referring to quantization in time/x-axis (sampling rate).
Quantisation is a potential factor but the graph does not show its effects and their comment describes the supposed effects sampling, not quantisation.
Also, when we come to discussing SNR, you’ll have to consider the SNR of analog systems too.
I should have been more clear: The negative effects of quantisation. Obviously sampling into discrete values is shown but not the negative consequences that can have.
A DAC interpreting the blue trace will output something extremely close to the red one. There might be a slight bit of error in it due to the quantisation before but the graph does not show that and it probably couldn’t since it’d be so tiny. A good way to show quantisation noise would be a histogram with a signal in the middle and some quantisation noise around it.
The DAC would not output the jaggy line. It couldn’t, that’s not a valid analog signal. Painting the steps between the points can be done if your audience knows what that means but can be extremely misleading if it doesn’t. Those lines between the points with 90 degree angles don’t exist in the real world, they’re just interpolated between the points in the visualisation.
A much better way to represent digital samples in such a chart is the way it’s done in the wikipedia article on the topic: en.wikipedia.org/…/Sampling_(signal_processing). They’re just discrete points. If you did the same interpolation between the points as a DAC would do (which is not nearest-neighbour interpolation), you’d get the analog trace shown.
Quantisation is a potential factor but the graph does not show its effects
Pardon me? The blue graph is obviously a result of sampling and quantization of the red graph. If there was no quantization but only sampling going on there would be exclusively vertical blue lines with precise values instead of quantized values and no horizontal blue lines because no data between samples. To be precise, the blue graph does not even show the precise values of the samples but only the results of the quantization of those. Exact sample values are only indirectly in this graph - they are where red graph and blue vertical lines meet.
However - I was primarily referring to OP´s idea that digital speedometers would be more precise than analog speedometers. If you look at the graph you will see that the analog speedometer always knows and thus displays the exact speed of the car in any moment (plus a small inevitable speedometer system delay). The digital speedometer on the other hand most of the time only knows the quantized value of the last taken sample - except in the exact moments when the samples are taken. Considering the quality (resolution and speed) of nowadays digital technology I assume this is not a factor to consider when designing speedometers though.
Interesting. Does quantization not always refer to quantization of the amplitude value of a sample while the sampling rate is always referred to as the … sampling rate? I get what you mean by quantization of time but I have never heard anyone calling the sampling rate that before, so now I´m asking myself if it even is a real quantization because there is no value approximation going on and the sampling frequency is an exactly known value at all times.
Yes I think you used the terms correctly — it should be referring to the amplitude. “Discrete sampling” or just sampling rate is the preferred way to refer to time, you’re right.
I was trying to use consistent language in response to the reply claiming you were misunderstanding the sampling theorem. I think that poster was confusing discrete/quantized steps in time with discrete/quantized steps in amplitude.
Does it make sense to mix my uses, i.e. media server, open project, etc. co-existing with file server for my docs and general files. Can I segregate portions for only local access?
Yes and yes.
I don’t have tons of time to maintain this. Nextcloud hasn’t been a pain, I log in here and there and make sure everything is updated (nextcloud and the server) and I run the NextCloud security scan to make sure I get an A+. Does it make sense to go for something like the better Synology NASs that can run docker images or would it provide better affordability/functionality to use a mini-pc or a FBmarketplace/craigslist slim pc hooked up to a drive enclosure or something else frankenstein-y. I don’t mind doing basic maintenance, but I can’t afford to spend every other weekend rebuilding things.
Most of the time, setting up for the first time and tweaking for maybe couple weeks top is a pita. I have not spent more than an hour a month after the initial setup phase. Realistically, you wouldn’t need more than what I spent.
I had one time that my OMV fucked up my docker containers but spent about 30 min and it was back to normal. All the other problems were network problems which will happen even if I used Synology.
I have a dead WD MyBook Live and MyBook Cloud on my shelf. WD never updated them to fix the critical security issues, I missed the 40% off upgrade window, and they’re not safe to run with network access. They also sucked even when they were new. I want to avoid products doomed to become dead-end abandonware before I’m ready to upgrade. Are there NAS brands that are known to be better/worse with this? How does homemade NAS fare as far as hardware support and having to upgrade/rebuild when OS versions change.
In the end, if you go with the premade NAS, you will want Synology. There are no real competitors in the market atm.
Homemade NAS has been constantly getting better. Trunas is amazing. OMV is nice although I’m using it just because I’m too lazy to upgrade to Truenas.
I can’t say anything about other NAS brands but homemade NAS is going to get basically the best and the fastest updates there is, depending on the OS of uour choice. They will be painless for most of the time.
Can I purchase/build a simple NAS that I use for storage and serve the files for my media server through a different device like my laptop? Is this better/worse than just streaming from the NAS itself or will I not notice in most cases?
If you’re using homemade NAS, that will be more than enough. If you’re using something like Synology, you’ll be fine but also want something better depending on your usecase.
It sounds like some of the pre-built machines can use drives of different sizes which would allow me to re-use the barely used drives inside of the WD devices. Do any of the self-build solutions allow for this
Check out Unraid. I personally would not do that though.
I would LOVE some book/media/community recommendations for digital hygiene and how to handle store, backup, maintain the deluge of information in our modern lives.
Even disregarding the trust issues with Flatpak packages made by random people: Packages often contain versions of some libraries in order to not depend on the distro's. If there are security vulnerabilities in a library then the distro maintainers usually fix it very quickly (if not go find a better distro) and it's fixed for all packages on your system that depend on it. But this doesn't apply to Flatpak where the package providers have to update the libraries in their own package - and the track record isn't great. Sandboxing doesn't help if that vulnerability leads to wiping your home directory.
I like pass, It’s just a wrapper around standard tools - gpg encrypted files in a directory, with git for version control. You can organize the subfolders however you’d like, and store whatever you want in them. You can sync the files across systems however you’d like - copy/paste, rsync, network drive… You can even go as far as to install a git server, e.g. gitlab, and clone, push, and pull into password synchronization bliss.
If you are running a media server, depends what you going to do with it. Storing media without transcoding you don’t need much, ex-gov computer from last 10 years x86_64 CPU that could store a HDD, you could use openmediavault (Linux), Unraid (paid - linux) or freenas (freeBSD) in a JBOD config and a ssd for cache (so you can serve databases, and metadata quickly, like plex or Jellyfin) and it will be much faster than MyBook Cloud.
Transcoding media, that is converting media from a format to another format so you can be compatible is a different story. You will need at bare minimum intel with quicksync or a fast CPU for software encoding.
Generally with DIY NAS software, you load a docker, point the docker directory (fake) to your jbod directory and it will just deploy on the webUI port you assigned it too.
Generally I will do this imo. Cheap intel PC (eg. Ex-gov) with a HDD > upgrade to SSD for a cache drive > DIY PC with plenty of SATA ports > upgrade to NVME > Cheap GPU for transcoding OR SAS card for more harddrives.
If the data is really important, make sure you have a parity drive and a backup solution.
With what I've seen of the US, I can see why many people over there would unironically hate cars. Car-centric planning has all but ruined the walkability of most US cities to the point of making it almost obligatory to own a car.
Come over to Europe and you'll be able to see the difference that planning has had clear as day.
