Now WTF!? Suddenly, @falsifian@www.falsifian.org’s feed renders broken in my tt Python implementation. Exactly what I had with my Go rewrite. I haven’t touched the Python stuff in ages, though. Also, tt and tt2 do not share any data at all.

By any chance, did you remove the ; charset=utf-8 from your Content-Type: text/plain header, falsifian?

Image

@movq@www.uninformativ.de Non-ASCII characters were broken. Like U+2028, degrees (°), etc.

Turns out I used a silly library to detect the encoding and transform to UTF-8 if needed. When there is no Content-Type header, like for local files, it looks at the first 1024 bytes. Since it only saw ASCII in that region, the damn thing assumed the data to be in Windows-1252 (which for web pages kinda makes sense):

// TODO: change default depending on user's locale?
return charmap.Windows1252, "windows-1252", false

https://cs.opensource.google/go/x/net/+/master:html/charset/charset.go;l=102

This default is hardcoded and cannot be changed.

Trying to be smart and adding automatic support for other encodings turned out to be a bad move on my end. At least I can reduce my dependency list again. :-)

I now just reject everything that explicitly specifies something different than text/plain and an optional charset other than utf-8 (ignoring casing). Otherwise I assume it’s in UTF-8 (just like the twtxt file format specification mandates) and hope for the best.

There is a bug in yarnd that’s been around for awhile and is still present in the current version I’m running that lets a person hit a constructed URL like

YOUR_POD/external?nick=lovetocode999&uri=https://socialmphl.com/story19510368/doujin

and see a legitimate-looking page on YOUR_POD, with an HTTP code 200 (success). From that fake page you can even follow an external feed. Try it yourself, replacing “YOUR_POD” with the URL of any yarnd pod you know. Try following the feed.

I think URLs like this should return errors. They should not render HTML, nor produce legitimate-looking pages. This mechanism is ripe for DDoS attacks. My pod gets roughly 70,000 hits per day to URLs like this. Many are porn or other types of content I do not want. At this point, if it’s not fixed soon I am going to have to shut down my pod. @prologic@twtxt.net please have a look.

Apple’s Phone App Finally Supports T9 Dialing in iOS 18
T9 dialing, or Text on 9 keys, is a predictive text technology that emerged in the 90s to make it easier to type text messages on devices with limited input options, such as traditional mobile phones with numeric keypads. Each number key (2-9) on a T9 keypad is mapped to a set of letters. For example, the key “2” corresponds to “ABC,” “3” to “DEF,” and so on.

So would they really place a navaid on a building that contains a UFO? I do not think so.
Would a UFO crash that close to Seoul without a since photo or video? I do not think so either.

So you would have:

type ErrPermissionNotAllowed []Permission
func (perms ErrPermissionNotAllowed) Is(permission Permission) bool {
    for _, p := range perms {
        if p == permission { return true }
    }
    return false
}
var err error = errPermissionNotAllowed{"is-noob"}

if errors.Is(err, ErrPermissionNotAllowed{}) { ... } // user is not allowed

var e ErrPermissionNotAllowed
if errors.As(err, e) && e.Is("a-noob") { ... } // user is not allowed because they are a noob. 

So you would have:

type ErrPermissionNotAllowed []Permission
func (perms ErrPermissionNotAllowed) Is(permission Permission) bool {
    for _, p := range perms {
        if p == permission { return true }
    }
    return false
}
var err error = errPermissionNotAllowed{"is-noob"}

if errors.Is(err, ErrPermissionNotAllowed{}) { ... } // user is not allowed

var e ErrPermissionNotAllowed
if errors.As(err, e) && e.Is("a-noob") { ... } // user is not allowed because they are a noob. 

@lyse@lyse.isobeef.org do you need to have an explicit Is function? I believe errors.Is has reflect lite and can do the type infer for you. The Is is only really needed if you have a dynamic type. Or are matching a set of types as a single error maybe? The only required one would be Unwrap if your error contained some other base type so that Is/As can reach them in the stack.

As is perfect for your array type because it asserts the matching type out the wrap stack and populates the type for evaluating its contents.

As is perfect for your array type because it asserts the matching type out the wrap stack and populates the type for evaluating its contents.

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?

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.

There was a MrBallen video with the same type of story. Some younger woman died of a heart attack while sitting up in her own coffin.

Rebooting a LUKS Encrypted System Without Typing The Passphrase: https://mckinley.cc/blog/20230526.html

I was able to fix this now, by making a ‘default.nix’ file, and then you can open a shell that has all the stuff needed by simply typing ‘nix-shell’ in the root git directory. Pretty nice, I’m starting to enjoy this OS more and more.

Here I am, looking at my bookshelf, where the ‘12 rules for life’ book sits.
I found the way he had to be put in a coma to get off addiction to his medicine etc fascinating. It felt like the good old ‘do as I say, not as I do’ type of thing. But hey - regardless of who you are or how strong you portray yourself - there can always be hard issues to tackle in life.

Isode: Red/Black 2.0 – New Capabilities

So. Some bits.

i := fIndex(xs, 5.6)

Can also be

i := Index(xs, 5.6)

The compiler can infer the type automatically. Looks like you mention that later.

Also the infer is super smart.. You can define functions that take functions with generic types in the arguments. This can be useful for a generic value mapper for a repository

func Map[U,V any](rows []U, fn func(U) V) []V {
  out := make([]V, len(rows))
  for i := range rows { out = fn(rows[i]) }
  return out
}


rows := []int{1,2,3}
out := Map(rows, func(v int) uint64 { return uint64(v) })

I am pretty sure the type parameters goes the other way with the type name first and constraint second.

func Foo[comparable T](xs T, s T) int

Should be

func Foo[T comparable](xs T, s T) int

decided to boot it again. turns out I typed the wrong encryption password yesterday, and instead of saying that it printed that error. booted fine now :)

@prologic@twtxt.net @movq@www.uninformativ.de this is the default behavior of pass on my machine:

I add a new password entry named example and then type pass example. The password I chose, “test”, is displayed in cleartext. This is very bad default behavior. I don’t know about the other clis you both mentioned but I’ll check them out.

The browser plugin browserpass does the same kind of thing, though I have already removed it and I’m not going to reinstall it to make a movie. Next to each credential there’s an icon to copy the username to the clipboard, an icon to copy the password to the clipboard, and then an icon to view details, which shows you everything, including the password, in cleartext. The screencap in the Chrome store is out of date; it doesn’t show the offending link to show all details, which I know is there because I literally installed it today and played with it.
