I don’t know if you’re being serious, but I can confirm from my time at as a developer at a banking software company, we didn’t use a hard RT OS even for like Mosler or Hitachi high speed check sorters. Just fast C++ code. (On Windows XP still, when I left in 2016)

(Work load is basically: batch of checks is loaded into an input hopper, along with check sized pieces of paper which are headers and footers, machine rapidly scans MICR lines and they go flying towards output pockets, and our code has something like 20 ms to receive the MICR data and pass back a sorting decision.)

I feel like objecting to the “General advice about email is don’t” thing but I don’t know if I understand the objections well enough to refute them. I self host email for mspencer.net (meaning all requests including DNS are served from hardware in my living space) and I have literally zero spam and can’t remember the last time I had to intervene on my mail server.

On one hand: My emails are received without issue by major providers (outlook, gmail, etc) and I get nearly zero spam. (Two spam senders were using legitimate email services, I reported them, and got human-seeming replies from administrators saying they would take care of it.) And I get amusing pflogsumm (summarizes postfix logs) emails daily showing like 5 emails delivered, 45 rejected, with all of the things that were tried but didn’t work.

On the other: most of the spam prevention comes from greylist, making all new senders retry after a few minutes (because generally a legit MTA will retry while a spammer will not) and that delays most emails by a few minutes. And it was a bear to set up. I used a like 18 step walkthrough on linuxbabe dot com I think, but added some difficulty by storing some use and alias databases on OpenLDAP / slapd instead of in flat files.

But hey, unlimited mail aliases, and I’m thinking of configuring things so emails bounce if they seem to contain just a notification that terms and conditions are updated somewhere. I don’t know, cause some chaos I guess.

And I have no idea if my situation is persuasive for anyone because I don’t know what the general advice means. And I worry it’ll have the unfortunate side effect of making self hosting type nerds like me start forgetting how to run their own email, causing control of email to become more centralized. And I strongly dislike that.

I’m surprised I’m the first comment saying this, but all I see is a user who needs help expressing their needs but who is not getting that help. Sure they don’t have our experience with decomposing problems and anticipating technical issues, but that’s normal and expected.

Yep, mspencer dot net (what little of it is currently up, I suck at ops stuff) is 2012-vintage hardware, four boxes totaling 704 GB RAM, 8x10TB SAS disks, and a still-unused LTO-3 tape drive. I’ll upgrade further when I finally figure out how to make proper use of what I already have. Until then it’s all a fancy heated cat tree, more or less.

I don’t think they meant to bite at anyone. I feel compassion for anyone who has been beaten down by our system and doesn’t have any fight left. I still have a little, and I take that statement as encouragement to keep fighting. Despair and depression are brutal and I’ll keep fighting for both of us.

Agreed, one of those “technically correct but deliberately missing the point” statements. Not sure why you’re so heavily downvoted so I want to explain why I support your statement.

The original statement doesn’t suggest they fail to understand words are constructed for sharing meaning, it asserts that the statements don’t communicate anything useful because the speaker made them up.

The statement is wrong, it needs a response, but “all words are made up” is not a useful response. It’s technically correct but fails to meet the speaker halfway by understanding their position and building towards it. See also: “all lives matter.” Technically correct but not useful, and deliberately avoids trying to understand the speaker’s position.

I couldn’t find the clip, but first thing that came to mind was the StarTalk Live with Buzz Aldrin and John Hodgman.

Hodgman: “maybe they’ll find H 2 2 2 2 O!”

Edit: crap, I have to call myself out. I failed to read completely, thought the screenshotted poster accidentally changed one part of the comparison, instead of deliberately changing both parts. If the original was molecules in a cubic inch of water vs stars in the observable universe, I read this post as atoms in a molecule vs stars in the observable universe.

Apologies, I discovered I was a fool and was excited to share my discovery.

Dear God do I hate how true that is. Not sure if intentional or not, but either way I’m with you. And I think they’re working to a plan.

I had a call center job while finishing college, but I’m currently a professional software developer. The difference in coverage is crazy. Dental crowns went from 25% to 75% coverage. My annual maximum out of pocket for healthcare is so low I keep hitting it by accident and wondering why things are suddenly free.

Why? I think it’s a deliberate plan to make life pretty good for like 51% of us, so we won’t vote against the way they absolutely wreck the other 49% of us.

I hope it stops working soon.

Same. Went from radiks.net dial-up to US-West business DSL. Registered my domain at the same time, mspencer.net

My first full time job was for Ameristar Casino Council Bluffs. I can say this: see all that fancy stuff? They built it with your money. They don’t need more of it.

I don’t know what people call this, but I’m curious if you also need future balance prediction, basically “here’s how much left over you’re going to have this payday, next payday, etc”. I might switch from my homegrown spreadsheet to one of these recommendations if they also support that.

(I’m talking about something where you input your known scheduled debits and credits, especially for people with biweekly paychecks but monthly debits, and then you match recent actual activity with what’s expected. So you get “current balance is $1800 but it’ll get as low as $300 before you get paid next” type info to keep you from over spending.)

I think image generators in general work by iteratively changing random noise and checking it with a classifier, until the resulting image has a stronger and stronger finding of “cat” or “best quality” or “realistic”.

If this classifier provides fine grained descriptive attributes, that’s a nightmare. If it just detects yes or no, that’s probably fine.

I have an iPhone and a gl.inet gl-e750 portable cell router, and my SIM card stays in the router. I don’t actually restrict my phone the way you’re talking about, but this gives me vpn to my home network without needing the vpn running on each client device. And if I wanted to block connections to big tech company services, I could do that.

Payment card transactions can be disputed or reversed. Cryptocurrency transactions cannot be easily reversed. Reversal is an important capability because sometimes customers or merchants lie, or they can have problems fulfilling their obligations.

When the buyer and seller are in the same country, or are in countries with legal and criminal justice systems which cooperate, transaction risk is lower so fees can be lower.

Not really, it’s been pretty effortless. Every couple months I have to make sure my renewed LetsEncrypt certs really got imported, but I don’t think I’ve had to intervene manually for anything in a long time.

I do, and I agree about their utility. My users and aliases are in OpenLDAP but it’s pretty easy to add new ones.

Separate accounts are preferable if you’re actually going to be responding to messages. I’ve had some embarrassing encounters where I’ve given an alias to a business that I didn’t realize was going to actually use it for real email conversations with a human. By default roundcube web mail lets you hit reply anyway and the reply goes out with your real address, which can lead to confusion.

I host my own for mspencer dot net, used this 15-ish step walkthrough from linuxbabe dot com. Only maybe three instances of spam in two years, gmail and outlook receive my messages just fine, etc. (Successful spammers were using legitimate services, and those services took action when notified. Greylist delays emails by a few minutes but it’s extremely effective against most spammers because they never come back to retry messages after a few minutes, while legitimate senders will.) I don’t know if I would accept blanket advice against self hosting.

Fundamentally if your mail server can see the addressee, it can see the content. SMTPS encrypts both in the same channel. So at the point where you accept messages and store them in a mailbox, the messages have to be readable.

Encrypting them at rest isn’t something I currently do, but if you’re going to later serve those messages to an email client that expects to receive clear text, your server needs both the keys and the messages. They can be stored in different places.

Most of your needs could be met with full disk encryption on the box hosting Dovecot. If you’re worried about being compelled to decrypt, there’s always the deck of cards trick: The pass phrase for full disk encryption consists of a memorized portion plus the letters and numbers of the top N cards in this deck of cards you keep by the server. If someone were to shuffle that deck of cards, and the server were powered down, the encrypted volume would be impossible to recover.

I’m eager to learn what other Dovecot tricks people can recommend to improve security.

Hmm, you have uncovered a problem with both of our ideas. Steam’s leverage is reduced after they have deposited sales proceeds, and is gone after the publisher isn’t selling games on the platform any longer.

(I’m griping about Rockstar specifically but my point is still flawed in the general case.)

Deceased users’ estates still haven’t agreed to the new terms, have they?

Now punish publishers who try to change the terms of sale after sale. “Want to play the single player game you bought a decade ago? Agree to this new arbitration clause.”
