@movq@www.uninformativ.de Thanks. I noticed the <updated> of the feed, too. But for some reason, some articles were suddenly marked as new.

On some YouTube feed <entry>s, I noticed updated <updated> fields showing today’s timestamps. But unless there is no <published>, the <updated> is not even considered. I verified that in the source code. Yet, all the affected articles in Newsboat show today’s timestamp, not the years old publication timestamp. I generate the YouTube feeds from the original feeds myself once a day, so I doubt that this is cause by some YouTube shenanigans.

Very weird, it doesn’t make any sense at all. What is going on here? O_o It doesn’t appear that I have duplicates in the database either.

I just missed the 20 year anniversary of my blog. 😬 What a stupid long time to do this.

This started out as a PHP page with user comments, MySQL as a database, a PHP webadmin … can you believe that? Totally unnecessary. But everything was “LAMP” back then, so that’s what I was using as well. I kicked out MySQL in 2011 (it just stored files since then) and eventually switched to static HTML pages in 2015.

RSS feeds have only been there since 2009, because I was late to the party. For a long time, I didn’t understand what they were good for. 🤦

The auDA, and some 3rd-party identify service and my Registrar are a joke!

WOW! I just had to share this little story I ran into today.

I tried to register a .AU Domain the other day, only for it to instantly fail.

I emailed support, which took several days to respond, only for them to respond by saying (paraphased):

We’re sorry, but the identify checks failed. The 3rd-aprty service doesn’t tell us why, But, please make sure that the ID you used matches the Full Name, including any Middle name(s).

I used my Passport number. Which of course has my First, Middle and Last Name.

I can only assume at this point that the checks failed on the missing “Middle name”. Why? Because the Registrar I use has a database and user interface for “contacts” that only have support for First name and Last name. NO Middle Name.

🤦‍♂️ This is basically stupid at this point. Systems cannot be trusted at the most fundamental level, no matter how good they are.

Until we figure out how to build a system that allows an individual to prove to another entity that they are who they say they are without a shred of doubt (i.e: cryptographically), we’re stuffed.

There is literally nothing I can do in this case. The auDA are at fault. The 3rd-party identify service (unknown) are at fault. The registrar are at fault. Hell, even the Passport office are at fault for even bothering to or requiring a Middle name.

How has “identity” come to this?

I’m supporting incremental SQLite schema changes to just upgrade from an older database version to whatever the current software version supports. In the past, I already noticed that this is quite expensive in unit tests when each test case runs through the entire schema patches and applies them one by one.

To speed up test execution I now decided that I finally go through the troubles of maintaining both a set of incremental patches and a full schema setup in one go. A unit test verifies that both ways end up with the same structure. This gives me a set of SQLs to check the structures:

SELECT type, name, tbl_name, sql
FROM sqlite_schema
ORDER BY type, name, tbl_name

Unfortunately, the resulting CREATE TABLE SQL queries are formatted differently, depending on whether the full schema was set up in one big step or the structure had been modified with ALTER TABLE. Mainly, added columns are not on their own lines but appended in one physical line. That’s why I wanted an SQL formatting tool. Since I didn’t find one that works decently, I’m now doing some simple string manipulation. Joining consecutive whitespace into a single space character, removing spaces before commas and closing parentheses and spaces after opening parentheses. This works surpringly good enough. Of course, if it fails, the “diff” is absolutely horrendous.

Now for the cool part, my test execution dropped from around 5:05 minutes to just 1:32 minutes! I call that a win.

I just stumbled across PRAGMA table_info('tablename') https://sqlite.org/pragma.html#pragma_table_info, PRAGMA foreign_key_list('tablename') and friends. I guess, I have to play with that, now. It’s probably much better to use than the SQL text approach.

@movq@www.uninformativ.de I noticed that your feed’s last modification timestamp was missing in my database. I cannot tell for certain, but I think it did work before. Turns out, your httpd now sends the Last-Modified with UTC instead of GMT. Current example:

Sat, 03 Jan 2026 06:50:20 UTC

I’m not a fan of this timestamp format at all, but according to the HTTP specification, HTTP-date must always use GMT for a timezone, nothing else: https://httpwg.org/specs/rfc9110.html#http.date

At around 19 seconds in the video, you can see some minor graphical glitches.

Text mode applications in Unix terminals are such a mess. It’s a miracle that this works at all.

In the old DOS days, you could get text (and colors) on the screen just by writing to memory, because the VGA memory was mapped to a fixed address. We don’t have that model anymore. To write a character to a certain position, you have to send an escape sequence to move the cursor to that position, then more escape sequences to set the color/attributes, then more escape sequences to get the cursor to where you actually want it. And then of course UTF-8 on top, i.e. you have no idea what the terminal will actually do when you send it a “🙂”.

Mouse events work by the terminal sending escape sequences to you (https://www.xfree86.org/current/ctlseqs.html#Mouse%20Tracking).

ncurses does an amazing job here. It’s fast (by having off-screen buffers and tracking changes, so it rarely has to actually send full screen updates to the terminal) and reliable and works across terminals. Without the terminfo database that keeps track of which terminal supports/requires which escape sequences, we’d be lost.

But gosh, what a mess this is under the hood … Makes you really miss memory mapped VGA and mouse drivers.

@prologic@twtxt.net In my opinion, the integrity isn’t lost. The same input data always result in the same output hash, no matter when you calculate the hashes. It’s true that a corrupt database contents yields to corrupt hashes, but then you have a whole bigger problem than just receiving different hashes. :-D

@zvava@twtxt.net By hashing definition, if you edit your message, it simply becomes a new message. It’s just not the same message anymore. At least from a technical point of view. As a human, personally I disagree, but that’s what I’m stuck with. There’s no reliable way to detect and “correct” for that.

Storing the hash in your database doesn’t prevent you from switching to another hashing implementation later on. As of now, message creation timestamps earlier than some magical point in time use twt hash v1, messages on or after that magical timestamp use twt hash v2. So, a message either has a v1 or a v2 hash, but not both. At least one of them is never meaningful.

Once you “upgrade” your database schema, you can check for stored messages from the future which should have been hashed using v2, but were actually v1-hashed and simply fix them.

If there will ever be another addressing scheme, you could reuse the existing hash column if it supersedes the v1/v2 hashes. Otherwise, a new column might be useful, or perhaps no column at all (looking at location-based addressing or how it was called). The old v1/v2 hashes are still needed for all past conversation trees.

In my opinion, always recalculating the hashes is a big waste of time and energy. But if it serves you well, then go for it.

@zvava@twtxt.net The problem you now then is you lose integrity of the message content if you compute the hashes at runtime rather than on the way in. So if your message content or database becomes corrupt in any way, so do your hashes.

@zvava@twtxt.net I might misunderstand what you wrote, but only hashing the message once and storing the hash together with the message in the database seems a way better approch to me. It’s fixed and doesn’t change, so there’s no need to recompute it during runtime over and over and over again. You just have it. And can easily look up other messages by hash.
