[chrisaldrich] hrusi[m] you'll notice on that example RSVP, that post looks like an article, but is doing double duty as an rsvp.
#
[chrisaldrich] You'll notice another one here https://events.indieweb.org/2020/09/domain-of-one-s-own-meetup-september-2020--908ut7UmA2T3 where I've done an rsvp data element on the part about the fact that I'm hosting.
#
[chrisaldrich] I really should have my post set up with h-event, but I haven't gotten that far yet... So for now it's an article with an embedded rsvp.

petermolnar !tell [James_Gallaghe] there is no pubdate on your webmention at https://jamesg.blog/webmentions/4.html
#
Loqi Ok, I'll tell them that when I see them next
#
Loqi [James Gallagher] I am feeling this way about my quantified self data. I like to share it on my site but the goal of my site is to share my writing and thoughts with the world. I do love sharing quantified self data but it comes with a lot of overhead. I only show ent...
#
hirusi[m] [chrisaldrich]: Yes I see it. I'm not sure what the...correct approach is but I'll probably take a look at that in the future. 😅

[tantek] URL design and dates thread: https://twitter.com/vincentlistens/status/1302532795068112900
#
@vincentlistens It turns out my bright idea to build my website urls based on date times was really really stupid. Don't ever do this and be me. It's a world of pain that means I'm going to have to rebuild almost everything from the ground up and alot of redirects to preserve the old urls :'( (twitter.com/_/status/1302532795068112900)
#
[tantek] spoiler: timezones lol
#
GWG [tantek]: I was talking timezones on the podcast and my EXIF issues
#
[tantek] yes. I have had DST issues with EXIFs myself!
#
[tantek] my solution to timezones and EXIF was to never change the time in my camera when I traveled to different timezones, so when I returned home, all the times were "correct" in my home timezone (which matches up with my published times etc.)
#
[tantek] however, iOS gets this "right" so I have felt "safe" changing timezones on my iPod and not worried about it not working properly when I get home
#
GWG [tantek]: I have a three part process
#
GWG Depending on what version of EXIF your file saved in
#
GWG The latest, where the times have offsets
#
GWG The previous, where the times have the offset saved separately
#
GWG Or the one before that that many still use where it isn't saved and I have to derive it from the gps coordinates
#
GWG And if it is a physical camera... compare to my logs
#
[tantek] GWG, one "trick" I used to do is to use my camera to take a photo of my watch right after changing my watch's timezone to the local timezone (I was going to land in, usually I did this on the plane to wherever the timezone was different). That way I could check/verify the timeoffset between the visual time on my watch and what time the EXIF claimed the photo was taken
#
GWG I still haven't solved tagging photos in EXIF
#
[tantek] as in long after the fact, when I had a collection of photos to go through, I could check these "timestamp marker photos" at the start / end of trips
nickodd left the channel
#
GWG [tantek]: I seriously considered having my site rewrite the EXIF
#
GWG I wonder if that is too much
jonnybarnes joined the channel
#
[tantek] I think it's useful to have the EXIF reflect what the camera captured
#
[tantek] rewriting might make sense if the camera's clock was set to the wrong time(zone) and you're "just" correcting that accordingly
#
GWG I was thinking about it for embedding my name and such
[jeremycherfas] joined the channel
#
GWG And adding the correct offset
#
GWG I have other priorities first... working on photo, video, and audio presentation again
#
GWG A lot of that is what metadata to display

#
[tantek] Thanks [jeremycherfas]. After one too many times of forgetting to set my Canon SD90 clock for DST, or getting confused about photo times & dates after returning from Australia, I found this to be the only way I could “reason” about what (local) time was it when I took the photo (which sometimes was in “the future”)

#
petermolnar from someone who tried to use EXIF as a meaningful storage: don't bother. It'll only cause you pain and suffering. If one insists, keep using the XML fields.
#
ndegruchy aren't there more than just EXIF type fields?
[LewisCowles] joined the channel
#
ndegruchy Yeah, looks like IPTC and XMP

Zegnat Is it just me, or did [jeremycherfas]' reply to [tantek] never made it from Slack to IRC?

sknebel I see a join for jeremys slack-representation, so not a netsplit I'd guess

#
GWG Just created a URL that 302 redirects to my user photo so I can change my photos without changing the URL. Trying to decide what cache/expires instructions I should set.
#
GWG And wondering if I'm better off serving the image instead of redirecting
