Question to all you Gophers out there: How do you deal with custom errors that include more information and different kinds of matching them?

I started with a simple var ErrPermissionNotAllowed = errors.New("permission not allowed"). In my function I then wrap that using fmt.Errorf("%w: %v", ErrPermissionNotAllowed, failedPermissions). I can match this error using errors.Is(err, ErrPermissionNotAllowed). So far so good.

Now for display purposes I’d also like to access the individual permissions that could not be assigned. Parsing the error message is obviously not an option. So I thought, I create a custom error type, e.g. type PermissionNotAllowedError []Permission and give it some func (e PermissionNotAllowedError) Error() string { return fmt.Sprintf("permission not allowed: %v", e) }. My function would then return this error instead: PermissionNotAllowedError{failedPermissions}

At some layers I don’t care about the exact permissions that failed, but at others I do, at least when accessing them. A custom func (e PermissionNotAllowedError) Is(target err) bool could match both the general ErrPermissionNotAllowed as well as the PermissionNotAllowedError. Same with As(…). For testing purposes the PermissionNotAllowedError would then also try to match the included permissions, so assertions in tests would work nicely. But having two different errors for different matching seems not very elegant at all.

Did you ever encounter this scenario before? How did you address this? Is my thinking flawed?

An official FBI document dated January 2021, obtained by the American association “Property of People” through the Freedom of Information Act.

This document summarizes the possibilities for legal access to data from nine instant messaging services: iMessage, Line, Signal, Telegram, Threema, Viber, WeChat, WhatsApp and Wickr. For each software, different judicial methods are explored, such as subpoena, search warrant, active collection of communications metadata (“Pen Register”) or connection data retention law (“18 USC§2703”). Here, in essence, is the information the FBI says it can retrieve:

  • Apple iMessage: basic subscriber data; in the case of an iPhone user, investigators may be able to get their hands on message content if the user uses iCloud to synchronize iMessage messages or to back up data on their phone.

  • Line: account data (image, username, e-mail address, phone number, Line ID, creation date, usage data, etc.); if the user has not activated end-to-end encryption, investigators can retrieve the texts of exchanges over a seven-day period, but not other data (audio, video, images, location).

  • Signal: date and time of account creation and date of last connection.

  • Telegram: IP address and phone number for investigations into confirmed terrorists, otherwise nothing.

  • Threema: cryptographic fingerprint of phone number and e-mail address, push service tokens if used, public key, account creation date, last connection date.

  • Viber: account data and IP address used to create the account; investigators can also access message history (date, time, source, destination).

  • WeChat: basic data such as name, phone number, e-mail and IP address, but only for non-Chinese users.

  • WhatsApp: the targeted person’s basic data, address book and contacts who have the targeted person in their address book; it is possible to collect message metadata in real time (“Pen Register”); message content can be retrieved via iCloud backups.

  • Wickr: Date and time of account creation, types of terminal on which the application is installed, date of last connection, number of messages exchanged, external identifiers associated with the account (e-mail addresses, telephone numbers), avatar image, data linked to adding or deleting.

TL;DR Signal is the messaging system that provides the least information to investigators.

In-reply-to » 💡 Quick 'n Dirty prototype Yarn.social protocol/spec:

I’m not super a fan of using json. I feel we could still use text as the medium. Maybe a modified version to fix any weakness.

What if instead of signing each twt individually we generated a merkle tree using the twt hashes? Then a signature of the root hash. This would ensure the full stream of twts are intact with a minimal overhead. With the added bonus of helping clients identify missing twts when syncing/gossiping.

Have two endpoints. One as the webfinger to link profile details and avatar like you posted. And the signature for the merkleroot twt. And the other a pageable stream of twts. Or individual twts/merkle branch to incrementally access twt feeds.

In-reply-to » Atom vs. RSS: https://mckinley.cc/blog/20221109.html

@mckinley@twtxt.net Thank you! I didn’t even know about signing and encrypting XML documents. Right, RSS is a little bit messy.

Unfortunately, the autodiscovery document in one of your linked resources does not exist anymore. What annoys me in Atom is the distinction between <id> and <link>. I always want my URL also to be my ID, so I have to duplicate that – unnecessarily in my opinion.

Also, never found a good explanation why I should add <link rel="self" … /> to my feeds. I just do, but I don’t understand why. The W3C Feed Validation Service says:

[…] This value is important in a number of subscription scenarios where often times the feed aggregator only has access to the content of the feed and not the location from which the feed was fetched.

This just sounds like a very questionable bandaid to bad software architecture. Why would the feed parser need access to the feed URL at this stage? And if so, why not just pass down the input source? Just doesn’t make sense to me.

Also, I just noticed that I reference the http://purl.org/rss/1.0/modules/syndication/ namespace, but don’t use it in most of my feeds. Gotta fix that. Must have copied that from my yfav feed without paying attention what I’m doing.

Your article made me reread the Atom spec and I found out, that I can omit the <author> in the <entry> when I specify a global <author> at <feed> level. Awesome! Will do that as well and thus reduce the feed size.

In-reply-to » Today I found that Solarpunk is a thing: https://www.wikiwand.com/en/Solarpunk

@abucci@anthony.buc.ci Its not better than a Cat5e. I have had two versions of the device. The old ones were only 200Mbps i didn’t have the MAC issue but its like using an old 10baseT. The newer model can support 1Gbps on each port for a total bandwidth of 2Gbps.. i typically would see 400-500Mbps from my Wifi6 router. I am not sure if it was some type of internal timeout or being confused by switching between different wifi access points and seeing the mac on different sides.

Right now I have my wifi connected directly with a cat6e this gets me just under my providers 1.3G downlink. the only thing faster is plugging in directly.

MoCA is a good option, they have 2.5G models in the same price range as the 1G Powerline models BUT, only if you have the coax in wall already.. which puts you in the same spot if you don’t. You are for sure going to have an outlet in every room of the house by code.
