trello indexing is bad

I have many examples of trello indexing for search failing, but here's one.

Search for "flight singapore london" returns no results. Actual card contains "fly singapore -> london", so fly and flight aren't treated as co-stemmed (whatever the term) by indexer. But in comment of card is "flights", so word and its regular plural by adding "s" aren't treated as co-stemmed?

I've added "keyword: flight" as a comment, and will see if that gets indexed and affects the search "flight singapore london" at some point in the future.

But in other cases, all the search terms do appear literally, but the search still fails.

More interestingly, playing with this raises some thoughts about application architecture.

Many applications are "eventually consistent".  New data is added, and at some point in the future, indexes are updated, linked records are updated, aggregates, and so on.  In almost no cases is there an indication to the user about this.  Could be "all up to date", or "records to receive", or "processing records",  or "disconnected; don't know if there are new records", and in all cases "this known as of timestamp, compared with now".  Where the data replication and processing can be handled by middleware, this is then reportable to the user in a uniform way.  On a traditional window frame, this could be indicated by an icon in one of several states.  On a phone (anything full-screen), some nook or cranny of the screen might be reserved for this.  Or it could be handled "inside" the application, but preferably as a secondary indication, with the OS / middleware one being definitive.  The only thing I've used that came close to this is Lotus Notes, in that applications had databases that got replicated at the Lotus Notes level, and could work disconnected.  But it was horrible to use.

Coming back to the case at hand, me adding "keyword: flight" would result in my search on other device saying "no results (but changed records from last 3 minutes have not yet been indexed)", or some indication on the screen that reprocessing is taking place.  And, kind of separately, why can't it brute-force search through this new record so that it does indeed present an up-to-date view?

the persistent idiocy of "privileged ports" on Unix

TCP and UDP have ports.  These are 16 bit; there are 65535 or so per IP address. These protocols don't care to differentiate between the ports.  Elsewhere, IANA presumes to operate a process to allocate "well-known" ports in the range 1-1023, "registered ports" in the range 1024-49151, and to reserve the remainder, 49152–65535, for "ephemeral" ports.  The caller end has to have a port, which is how replies get back within the virtual connection, and these are conventionally picked from the ephemeral range by the OS's networking stack. The whole idea of ports is ridiculous, because it allows ISPs to arse around presuming to decide which services they will "not allow".  Anything that allows IPSs to do anything other than shift opaque packets will allow ISPs to meddle and break things, and due to the Law of Meddling, if they can, they will.  I am currently working around an issue with Claro, a pretend ISP, blocking port 5060, allocated to SI...

difference between timezone and offset

This is something I tried and failed to explain to a Computer Science graduate some years ago.  The Computer Science graduate assumed I was trying to make a point about seconds difference between UTC and GMT.  No.  I hope this doesn't count as slop, but Gemini can put it pretty well: User Question 1 what is the conceptual difference betwen a timezone and an offset AI Response 1 While they both help us tell time across the globe, a time zone and an offset are fundamentally different concepts. An offset is a static mathematical calculation, while a time zone is a dynamic geographic region governed by local laws. What is an Offset? An offset is the exact amount of time added to or subtracted from Coordinated Universal Time (UTC) to get the local time. Format: It is always expressed as a plus or minus sign followed by hours and minutes (e.g., +01:00 or -05:00). Nature: It is purely digital and mathematical. Limitation: It does not account for daylight saving time (DST) o...

shannonizers fail at logic

 some people have been wittering on about “AI”, as though it’s this or that. according to derpawerp, they are even going to take over the world. i asked one what’s the third-most populous city in new zealand, and it said something implausible. it then claimed auckland was the second-most populous. immediately after, it said auckland was the most populous, but didn’t notice its mistake. i had to “prompt” it, by asking whether the same city was really the first and second most populous. at which point, of course, “you’re absolutely right”. but it continued, with a straight face, making not just incorrect, but blatantly incoherent, claims about city population rankings. these word salads don’t just fail on basic facts, they lack the self-awareness to pick up on themselves when, according to themselves, they are being ridiculous. one was bugging me for pictures ideas, so i said draw a projection of new zealand onto northern hemisphere, flipping latitudes and lining up the other axis wi...
