I assume you mean running btrfs on top of md (mdadm) or dm (dmraid), not the other way around?

miedpo · 2 years ago

Woops, you are correct! And it looks like it is dmraid, not mdadm.

Sorry about that!

Anecdotally and absolutely not production experience here, but I've had a Synology device running btrfs for 7 or 8 years now. Only issue I ever had is when I shipped it cross country with the drives in it, but was able to recover just fine.

This includes plenty of random power losses.

miedpo · 2 years ago

They do use btrfs. However, Synology also uses some additional tools on top of btrfs. From what I remember (could be wrong about the precise details), they actually run mdadm on top of btrfs, and use mdadm in order to get the erasure coding and possibly the cache NVME disk too. (By erasure coding, I mean RAID 5/6, or SHR, which are still unstable generally in BTRFS).

The Icelandic volcanoes are a very different kind. They create lava flows instead of explosions (except when they erupt under glaciers, but there is no glacier near Grindavik). Another example is Hawaii, where the village of Volcano is only a few miles from the crater, which has been active almost continuously for over thirty years.

This is almost completely correct. However, I have heard of one other possibility that might be a problem - a steam explosion (maar).

From what I understand, a person died falling in a crack in town earlier this week, and when they went down to investigate, they found ocean water in it. There is a possibility (albight slight) of magma finding it's way into such cracks and causing a steam explosion. Nothing on the scale of something like what happened at Hunga-Haapi earlier last year, but still a not-so-great explosion.

Comments here seem to suggest that Nextcloud isn't worth it. Later today I'm supposed to talk with some folks at IT looking for an in-house file-sharing/collaboration tool that Dropbox/GoogleDrive is (or was, because after GoogleDrive price hikes our institution ditched them). I was going to suggest Nextcloud as a possible option to investigate...

miedpo · 2 years ago

I'm using Nexcloud currently, but an alternative for you to check out for you might be Pydio.

It has a lot of the same features, and generally seemed a little more stable. However, it was a little more painful to configure, and has a few unique terminologies you'll have to get used to. Also it's UI does load faster than Nextcloud, but once loaded, it is a little less snappy.

For the user downloaded client, I found that it works, but is a little less convenient than Nextcloud (no Automatic pinning of the folder, no partial downloads to save space)

I know everyone says it's not practical to run your own mail server, but I wonder if it's something I should have another look at. Even though this article says the cost of SES is 12:1 vs self managed infrastructure, and it's likely that SES is on the cheaper side of things, it's not really about the cost for me, it's about the loss of control.

I don't like having the potential for changes I can't control. It almost feels like I need two of everything just to be safe.

I wish some of the up-and-coming auth systems (ex: logto.io) would have some kind of tiered fallback for transactional email. For example, I have self hosted mail that's tier 1 (use first), AWS SES as tier 2 (use for failover), and Postmark as tier 3 (use as a last resort).

The reason I list Postmark last is because there is a point where price becomes a factor for me. If Postmark is 10x SES for 50k messages, and SES is 12x self managed infrastructure, that's 120x costs (12,000% markup), right? I feel like that's so expensive I might have gotten it wrong, so please correct me if I did.

miedpo · 3 years ago

Self hosting the infrastructure is incredibly easy. There are a lot of products out there that make hosting your own email system a cinch. One I'd personally recommend would be Cloudron, but I've heard MailCow is very easy, and I'm sure there are many other tools out there that sort of just 'do it for you'.

Email deliverability on the other hand is... I'm going to say, it's not hard, but not easy either. Mainly you have to deal with blacklists, as well as certain providers being a bit weird. Staying off of blacklists can be both easy and hard. Most blacklist providers have several different layers of "Don't accept email from this server". The highest layer is easy to stay off of - just don't send spam. The layers below it might not be though. In particular, if your IP address is even in the same range as where other people might be sending spam, your going to end up on a blacklist because of it. So certain blacklists might have a 'Level 2' or 'Level 1' where if you use the same VPS provider as a spammer, your VPS that's never sent spam is going to get some of that 'bad reputation'.

Email servers deal with blacklists in different ways - some just accept most things, some are a lot more strict. Usually email server will count up indicators for spam, and score them, and then, if it's above a certain score, the email bounces. Usually having a little 'bad reputation' (like from Level 2 / Level 1 like I listed above) won't be enough 'score' to effect things, but having a lot of it certainly will. I had an email server hosted on a VPS with a Level 2 warning, and my Gmail still got my emails. But I don't know if my emails would go well to all email providers (didn't do enough testing). In addition, some email providers will silently fail your emails if they don't pass - Google is pretty notorious about doing this. So it can be a bit of a pain to debug problems.

The advantage of SES is that they deal with the reputation problem. They will jump on a Level 1 for a few days, then stay off of it for the rest of the month, then jump back on it again, and the cycle repeats. This is for the generic shared IP form of SES, so it's pretty good. It's certainly going to be more expensive, but you will need to send a good amount of email before it make sense to start managing reputation on your own probably.

If you want the best of both worlds (although this sounds like what you are already doing), I'd suggest hosting your own server, but then using Amazon SES as the outbound email relay. Amazon's outbound costs are very very cheap, and that's what you need the reputation for anyways.

It would be really nice if there was a system with fallback relays though, I agree. Let's hope that happens sometime :).

wizzard0 · 3 years ago

There’s a reimplementation of the Tailscale control plane called Headscale, if you want to self-host.

I’d try to use that first, because sadly Nebula and ZeroTier don’t have a relay/TCP/HTTPS fallback option and still “have no plans of implementing one” as of Mar 2023, which leaves you out of luck as soon as you encounter NATs or try to access your cluster from an airport/hotel wifi

Maybe you know of other mesh/p2p VPNs that do support TCP fallback though? Would be great to see some alternatives in this area

miedpo · 3 years ago

Pretty sure ZeroTier supports relaying (I remember reading some of their earlier blogs and it mentioning something to that effect). In practice, you just have to turn off the uPnP in Settings to use it I've found.

Edit: Yep, just found a reference to it: https://docs.zerotier.com/zerotier/troubleshooting/ (Sorry, no direct link, so you'll need to Ctrl-F and look for Relay)

Cool! Separate question: What makes people decide to use a mail client instead of webmail? What can I do with a client that I can't do with Gmail web?

miedpo · 3 years ago

It's just a bit more snappy and has a few advanced but helpful features that gmail does not.

For comparison... think about how it feels to work in Microsoft Word compared to Google Docs. You can do most of what you can do in Word in Google Docs, but there are helpful things in Word that just make it that much better. And it just feels a little better when you use it... thus, if you need to do really serious word processing, you do it in Word.

Outlook and Thunderbird have a similar feeling when compared to gmail. It won't matter much if you are only sending 10 emails a day. But if you are sending 50 or 60 emails a day over multiple inboxes (particularly in the context of business email)... you might find it's a little easier to organize and respond to people in the desktop clients.

In the case of Thunderbird, here are some features it has I probably couldn't live without:

-Archiving split by Month (As a bonus there is also an easy shortcut key for archiving)

-Open in thread (this is a little different than gmails as far as I understand in the way that thunderbird deals with split threads, which can be important in a business context where you have some replies only going to some people, others going to other people - it's easy to see this tree structure in Thunderbird)

-Folders AND Tags (Thunderbird's Tagging and Folder system are separated, gmails is combined as far as I'm aware. As a bonus, Thunderbirds tags highlight emails in color for easy identification, and also have easy shortcuts)

-Add-Ons (For example, I use a Thunderbird extension that can attach notes to an email message... which can then synchronize between computers which is useful for accounts where a lot of people access the inbox, but where sending an internal email would clog said inbox. For gmail, you can write web extensions, but Thunderbird has an ecosystem already pre-existing and mostly free)

-Reminder if you use the word 'attach' and don't have an attachment (It sucks when you send out an email saying 'such is attached below and it's not actually there. Gmail might have this too now - have not checked.)

These things all seem pretty small but they make a big difference in how I manage my email, and especially with Thunderbird, this is all customizable. Want Unified inboxes, or separate ones? Your choice. Want to see the cc's from an email as a column in your email list, but not the favorites ('important' tag in gmail) column? Your choice too. And there's a lot more options than just these, meaning you can really streamline your email process. And this just ... at least for me, makes enail a little less painful.

Just my two cents :).

miedpo · 3 years ago

Hey,

So I would probably avoid Amazon just because many of their services charge for data out. It isn't out, but it's a variable for you, and you probaly want something that's flat per month. Cheapest you are going to get with somewhat reliable service is either going to be Hetzner or BuyVM. Hetzner is better for someone who doesn't want to tinker, BuyVM for those who do (BuyVM is a little less reliable, but you can set it up cheaper if you are willing to do a little bit of manual work with shell commands).

Secondly, I'd suggest you host this through Cloudron. It helps you handle automatic security updates and backups. It's very nice, and worth paying for, although it's a little pricey for individuals.

Third, with email, you can host it yourself (in fact Cloudron has this built in), but I'm going to recommend against it, or at least recommend that you pipe important emails through another service like Fastmail. Let me explain why. There's going to be some point after hosting for 5 years, where your server is going to go down. Now email will be fine, it's built to deal with cases where servers go down, but... we rely so much on email right now, that it's going to really suck to have it down. So by all means, have your personal email come to the server, but keep anything that you can't do without running on a managed service. You can pipe it through your own domain, and set up automatic forwarding, but it's going to be a little better to run important stuff through someone else's server, imho.

Just my two (or three, I guess) cents.

Nothing posted on some companies website is governed by free speech or the USA’s 1st amendment. The Terms Of Service apply and typically a user has agreed to those by simply participating on the site. This includes account bans, blocking content, etc. the company can do whatever it pleases, if it benefits them to listen to a gov’t agency request then they might do it.

Its comical that people believe Musk is promoting free speech or anything of the sort. Most of everything he does online is antics to draw attention in some way that benefits him, go look at the SEC for details around that with Musk.

I would make a bet one of his next options is to saddle Twitter with more debt as it approaches bankruptcy. Or give insider info to his investors ahead of his next Tesla sell-off so they can recoup their losses with Twitter.

miedpo · 3 years ago

Just responding to one part of this, if that's cool.

I think what the comment above is saying is that it's not about whether or not speech on Twitter is protected. It's that the government isn't supposed to act to restrict speech in any manner that doesn't cross the lines he listed.

If I'm remembering correctly, there was a big court case because Trump was hiding critical responses to his tweets on Twitter. The judge ruled that Trump violated the 1st amendment even though Twitter is a private company ("private property"?).

This is because the 1st amendment not only protects speech, it restricts government attempts to control speech (or at least that's the argument that would be made).
