== Google Earth app ==
 +
 
 +
It would be interesting if we could somehow tie these pictures that people are uploading in with the google earth program- an app that lets you select a graticule, get a list / visual of points that have been geohashed, and retrieve pictures specific to those points.

:I'm already generating a KML file that can be used in google earth (and maps) to look at active graticules.  If there was a page listing all the images and where they should be placed, it would be trivial to include those images there as well. [[User:Zigdon|Zigdon]] 23:28, 25 May 2008 (UTC)
 +
::Since all of the pages for specific meetups have the same URL format, they could just be scraped off of the meetup pages- if the meetup page has that image on it, it gets listed for that location. There's probably an easier solution though...
 +
 
 +
==Meeting Standards==
 +
In the case that the Geohash for the day falls in a crowded place or just for a conversation starter I propose a standard way of letting the "in" crowd know you are a geohasher, besides the obvious raptor signs etc. perhaps a red shirt or a Madagascar flag something for people to look for.

:How about the google maps red pin? Though more generally, I think if such a marker is needed, it can probably be pre-organised per graticule.  --[[User:Nemo|Nemo]] 22:30, 3 June 2008 (UTC)

When I was on my way to the hashpoint I wanted to have a secret sign and countersign so I could say, "Did you see the fish?" and if they were indeed geohashers they would reply, "the fish wears a hat," as opposed to the "Huh?" or "What fish?" replies one would expect from innocent bystanders.

== Embedded video ==
 +
 
 +
Is there a way to embed YouTube and/or Vimeo video in the wiki?  This would be especially useful for Speed Racer hashes, e.g. [[2008-06-07_42_-71|2008-06-07 42 -71 Boston]]. --[[User:Nothlit|Nothlit]] 22:37, 7 June 2008 (UTC)

== Unofficial Invitations ==
 +
 
 +
Hey all, sorry for editing directly on the main page. I actually only wanted to change tomorrow's suggested meeting location, but couldn't drag it out of the graticule. Anyway, maybe others also like the idea. If not, feel free to remove it again. (After my summer solstice party tomorrow. ;) )

: Agreed.  Some template scripts (such as [[Template:Next Saturday]]) rely on the server time to present information in a timely fashion.  If the time is unreliable, so become the templates, and thus parts of the wiki.  --[[User:Tjtrumpet2323|Tim P]] 14:07, 17 June 2008 (UTC)

== Listing elements of a category ==
 +
 
 +
Probably it is not the right place to ask, but i didn't find out where to ask.
 +
Is there a possibility to list the elemnts of a category on a page?
 +
I know i can link it, but is there a way to show it right there?
 +

: As far as including the elements of a category, I know you can transclude the ''text'' of category directly onto the page by using <code><nowiki>{{Category:CATEGORYNAME}}</nowiki></code>, but I don't know how to include the elements, or even if it's possible.  --[[User:Tjtrumpet2323|Tim P]] 13:29, 20 June 2008 (UTC)

 +
::: Er, my name's Tim, but you're welcome anyway.  ''':)'''  Did you actually include the <code><nowiki><code></nowiki></code> and <code><nowiki><nowiki></nowiki></code> tags?  Does the category actually have "text" in it, ''i.e.,'' is it a blue link when linked to?  That's the only way you can transclude the ''text''; as I said earlier, I don't think that transcluding the ''elements'' is possible.  Could you paste a specific example below, along with an explanation of what you're trying to do?  Thanks.  --[[User:Tjtrumpet2323|Tim P]] 22:43, 20 June 2008 (UTC)

 +
:::: I'm really sorry. Your name's corrected.
 +
:::: I did not include code+nowiki, i thought i shouldn't if i wanted it to work. (Should I?)
 +
:::: Anyway. What i'm trying to do is this: A user can put the a/s/l template on his page. By doing so he's automatically gets a category, like "Geohashers in X, Y". I wanted to automate maintaining the local geohashers section of my X, Y graticule page by inserting a link to the category "Geohashers in X, Y" somehow to that place. I thought i could somehow make the wiki page show a list of the users in the category "Geohashers in X, Y" there, just like it does on the main page of the category. --[[User:Tomtom|Tom]] 23:07, 20 June 2008 (UTC)
 +
 
 +
::::: I'm sorry; I must have misunderstood you.  As far as I know, there's no way to transclude the ''elements'' of a category directly onto a page; ''i.e.,'' you can't automatically list geohashers who have added the template on any page other than the category page itself.  The only thing you can do is transclude the "description text" of the category, which wouldn't be very useful at all.  Sorry!  --[[User:Tjtrumpet2323|Tim P]] 18:26, 21 June 2008 (UTC)
 +
:::::: Yeah, i'm not a native english speaker, so the word ''transclude'' was not at all in my mind. I was just thinking that there's surely a way to collect the titles of the pages that contain the category template (? i don't know if template is the right word here, i mean <nowiki>[[Category:SOMETHING]]</nowiki>), just the way the category page itself collects them. (I mean, for example me and other users put <nowiki>[[Category:Geohashers]]</nowiki> to our userpage, and we are automatically being listed on the page of the category) I thought this listing can be programmed somehow similarly on an other page too. --[[User:Tomtom|Tom]] 12:34, 22 June 2008 (UTC)

:::::: (Of course i can believe that it can be impossible.) --[[User:Tomtom|Tom]] 12:36, 22 June 2008 (UTC)

== Front Page Coordinates ==
 +
 
 +
If I'm reading the front page source code correctly, I think that the front page's coordinates are generated automatically via a template...and that template doesn't seem to be working correctly!  I get today's (2008/07/31, W of -30) coordinates to be .5356742, .4584283, but the front page differs.  Is this a bug that needs addressing?  --[[User:Scottkuma|Scottkuma]] 14:41, 31 July 2008 (UTC)
 +
:Looks like. We had a problem at the end of June also - I think it's something to do with generating two sets of coords. --[[User:Thomcat|Thomcat]] 15:03, 31 July 2008 (UTC)

== Complete list of historical locations ==
 +
 
 +
Surely someone has by now generated a complete list of the decimal parts of the coordinates produced by the historical data?  It can't just be me wanting to see it, can it?  Does anyone have a link to one if so?  Even better if it was available as a map overlay...
 +
 
 +
: I put up a set of [http://www.bunkmonkey.com/HistoricalLocationData.csv Historical Location Data] that I generated a couple days ago. It seemed slightly too ginormous to put on the wiki in it's raw form, but if anywone wants to, be my guest. Unfortunately there are some bad dates in there due to Dow data that was missing, but I'll get them updated. My hope was to use the data to generate a map overlay or allow you to click a location on the map and have it show you all the dates that a geohash landed in the vicinity, but my web programming skills are nonexistent. I could write a Windows app, but that's not so great for anyone. Someone else tackle it. :) --[[User:ZorMonkey|ZorMonkey]] 11:57, 27 May 2008 (UTC)

::::Wow, nice! With that I regenerated my [http://www.bunkmonkey.com/MilwaukeeFrom1928.zip Google Earth KML file for Milwaukee].

: Once you have one of the data files, it's pretty easy to generate a KML file for Google Earth. Google Earth freaks out a little bit, but it works! Here is [http://www.bunkmonkey.com/MilwaukeeHistoricalGeohashLocations.zip a sample KML file (zipped)] that I generated for the 4 graticules near the Milwaukee area, and the Python code I used follows. I've just started learning Python, so forgive any hackityness. In this state it needs to be manually tweaked to generate other graticule information, but it's pretty easy.

::: [http://hermidownloads.craqstar.de/geohashing/geohashing_historical_converter.zip My python code] is just like yours (I heared about python in the comics the first time).

None of the placemarks are displayed except the ones mentioned in the corresponding wiki page (i.e. have expeditions).

== Mother Nature vs. The Internet vs. Civilization ==

I would really love to see a score table

;Mother Nature vs. The Internet vs. Civilization
 +
sorting all the hashes into 
 +
* failed because of weather and/or landscape
 +
* successfully reached
 +
* failed because of man-made obstacles (fenced in, no trespassing, failed GPS devices and the like).
 +
* (any other reasons? laziness would account for a draw IMHO.)
 +
However that would mean to parse through all past expeditions and classify the expeditions.
 +
 
 +
What do you think of the idea? Could it be realized to remain easy to maintain, when adding future expeditions - use Categories maybe? Would you be willing to help? -- [[User:Relet|Relet]] 00:54, 27 July 2008 (UTC)
 +
 
 +
: Cool idea. I'd be willing to reclassify mine. You can see reasons I have failed on my user page. The extra category should encompass laziness, chickenness, and our own errors. Data collected based on hash reports would, however, leave out the geohashes never attempted because it was obvious that mother nature or civilization would win the day: in my graticule that's all the ones on glaciers or mountains, or in the protected watersheds. - [[User:Robyn|Robyn]] 05:34, 27 July 2008 (UTC)

::I agree with Robyn, and definitely use categories.

:::These should only be used for actually attempted expeditions. I don't think that it makes sense to include non-attempted expeditions.

 +
:::Hmmm, definitions time. An "expedition" is when people set out to attempt a geohash (or meetup). I like "defeated" but it's a little wordy, and don't want to tie it to the expeditions. Nature can nearly always be beaten, given time, money, and effort. How about ''Category:Coordinates Reached'', ''Category:Coordinates Restricted'' and ''Category:Coordinates Unreasonable''? I tried unreachable, but that covers restricted as well. --[[User:Thomcat|Thomcat]] 17:04, 31 July 2008 (UTC)

::::Additional - ''Category:Coordinates Unknown'' covers the weekend we had coordinate problems (May 31) and a few others where people made an expedition without a GPS and reported they weren't sure if they made it or not. Any other discussion on these categories? --[[User:Thomcat|Thomcat]] 00:28, 2 August 2008 (UTC)
 +
:::I like the wordy version better, since it goes along the Mother Nature meme. I don't mind another wording, though. Coordinates Reached and Coordinates Restricted are clear to me, but "Unreasonable" does not bear the same message (the failure having natural causes). IMHO, that would include expeditions which weren't attempted in the first place. My idea was to separate into success/man-made obstacles and failures/failures caused by force majeure; natural causes. But maybe we can just separate into Success/Failure in a first step, and then see whether to further classify the failures.
 +
:::Not knowing your coordinates / failing GPS / relying on your memory of Google Maps is a human failure IMHO. ;)

:::Nature can "always be beaten", if you're prepared for everything. But she's good at catching you off guard. Just think of the raptors. And you've only got a few hours-days for preparation, depending on when and where to go. -- [[User:Relet|Relet]] 23:00, 2 August 2008 (UTC)

: Caveats - I use the best possible category, i.e. if some gave up but other succeeded, that counts as success. Proven non-public areas will nearly always be failures, unless somebody qualifies for [[Restricted Area Geohash]] or the like. Finally, if the spot is within error for the GPS (less than 10 meters usually) but unreachable, that's a success - it's happened to me twice. --[[User:Thomcat|Thomcat]] 16:43, 4 August 2008 (UTC)

== Numerical graticule redirects... ==
 +
 
 +
I'd like to propose that each graticule have a page named for the graticule's numerical coordinates.  For example, I've created a simple page for Cincinnati, OH at [[39 -84]] that is a trivial wiki redirection to the main [[Cincinnati, Ohio]] graticule page. In this way, it becomes VERY easy to write coordinate maps that link to adjacent areas, and it also becomes easier to computatively traverse coordinates to see what is available. Any suggestions/comments? -[[User:Scottkuma|Scottkuma]] 16:07, 4 August 2008 (UTC)
 +
 
 +
:I always thought that to be the convention already. '''Support''', but with a comma and no spaces, as in [[39,-84]]. :) -- [[User:Relet|Relet]] 16:08, 4 August 2008 (UTC)

 +
 
 +
::Better than a '''lot''' of redirects could be ... a template (e.g. '''graticule 39 -84'''). The template could do the lookup on the [[All Graticules]] page to display and link to the name. I have too little experience with templates to know if this is impossible. --[[User:Thomcat|Thomcat]] 16:26, 4 August 2008 (UTC)
 +
 
 +
::Yes, this is already done on an as-needed basis for the [[Template:ASG|ASG template]].  Generally, inactive graticules do not have this redirect because it is unnecessary.  If you want to code something to traverse graticules, try traversing using the [[All Graticules]] page. -- [[User:Moose Hole|Moose Hole]] 17:21, 4 August 2008 (UTC)
 +
 
 +
'''Seconded.'''  The convention for such redirect pages has been to use a comma and no spaces, influenced entirely by [[Template:ASG]], which was the first feature to require such redirects.  If you want to create a system of such pages to facilitate the inclusion of neighboring graticules, go for it!  --[[User:Tjtrumpet2323|Tim P]] 18:38, 5 August 2008 (UTC)

The pictures are manually added, so they don't update until someone (a) goes on an expedition and (b) chooses to show of his or her pictures. They load quickly for me, so this is my guess at what you meant, even though it's not what you said. Relatedly, I notice that the Upcoming Coordinates for Tuesday W haven't updated yet, though, even though they have been available for fifteen minutes. - [[User:Robyn|Robyn]] 13:47, 5 August 2008 (UTC)

:I think Psud means that he adds a picture, and it doesn't show up on the main page, even if he does a CTRL-F5. I've noticed that also. The pictures are running through a template, which (I'm guessing here) is connected to a database. They've always shown up within a few minutes for me, though. --[[User:Thomcat|Thomcat]] 14:19, 5 August 2008 (UTC)

:: As far as MediaWiki is concerned, there '''is''' a good reason for this... caching.  In order to reduce server load, complex templates are cached and are only reloaded/recalculated when an edit to the page housing that template is made.  However, there is a little known "purge cache" workaround that will force the server to regenerate the page if you want.  Simply add the code <code><nowiki>[{{fullurl:{{FULLPAGENAME}}|action=purge}} Refresh the cache]</nowiki></code> to any page to add a link which will purge the page's cache.  I've added this code to [[Main Page]] already, as I'm sure this is where it is most wanted/needed.  --[[User:Tjtrumpet2323|Tim P]] 18:35, 5 August 2008 (UTC)

==Automation of Coordinates Box==
 +
 
 +
I have been doing some work in attempting to automate the coordinates box for the Main Page. You can see it in [[User:CJ/sandbox/Coords|my sandbox]]. The problem I'm having is that I know '''how''' to make it happen, I just can't get the Wiki to '''actually''' make it happen. Once I try to get it to display more than four lines of data in the table it seems to freeze up the Wiki. I'm guessing it is something to do with there being too many if statements or template call-ups.
 +
 
 +
I have successfully automated the table without a colspan=2 effect for the weekend coordinates, but it just doesn't look as slick as having that effect in there.

== Shifting coordinates==
 +
For some reason I have noticed that of this week (and possibly earlier?) if I check the coordinates within an hour or so after they are released they give me one certain point for that day's hash location, and then if I check again a few hours later they have changed to generate a different point for the same day!

I had the same problem while doing planning [[2008-09-18|this morning]]. Doc Wilco told me on IRC that when the markets first open some values are not known, only estimated and that the number is adjusted for a little while. Perhaps the extreme shakeup in the markets recently made that go on longer than usual this morning.

== a few questions - graticule map, accuracy required, geotudes ==
 +
 
 +
Hi.... just some stuff
 +
 
 +
1/ the "online map of active graticules" seems a little out of whack, it doesn't include my fairly active home graticule, but does have a neighbouring and decidedly dead one listed and clickable. Is there any way we can edit it, suggest updates, etc?
 +
 
 +
:It's a wiki, you edit what you know, so go for it. Consult [[Creating a Graticule Page]] for instructions, and leave me a message if you have any trouble. -[[User:Robyn|Robyn]] 13:18, 13 October 2008 (UTC)
 +
 
 +
::It parses the site [[All Graticules]] list once per week. -- [[User:Relet|Relet]] 13:21, 13 October 2008 (UTC)
 +
 
 +
2/ what sort of absolute accuracy will be accepted in terms of a geohash success/fail? EG my main method of quickly checking up on them at the moment is an old copy of Autoroute (as there's no internet wait times, and it can easily remember a huge number of pushpins without any of google maps obtrusiveness) - but this only goes to an accuracy of 4 decimal places after the graticule degree, which in my area translates to something like a 10x20 metre square... is it enough to figure out I'm somewhere within that square (no GPS right now either - i'm a poor scrub!) and provide photographic proof of such that can be checked against aerial photos? most of the nearby locations that have come up so far are fortunate enough to have been in an open field next to a half decent road, so if anyone was there, or if a marker had been left, they/it wouldn't be difficult to see & shout to/find & add to.

::There are no rules per se. If you feel you're *there*, it's usually good enough. More specifically, a 10m GPS error range is considered acceptable by most hashers. Also, if you are in a situation where you easily could have come closer, but common sense tells you not to (e.g. trampling flower beds or fields) it's ok. If there is a big fence between you and the spot you identified, your feeling will tell you it's a FAIL. -- [[User:Relet|Relet]] 13:21, 13 October 2008 (UTC)

 +
3/ ok, i'm no maths genius, but fairly competent and took it til age 17 at school. But I can't understand half of what's going on with that GeoTude page. I get the concept but their formulas confound me - what's all this "Floor", and alpha/beta business? I know it's a seperate site but they have no contact details whatsoever, and I've seen at least one page here where someone describes an area using those co-ords. I know it'd be a useful tool and they have an online converter anyway, but I'd prefer to actually understand the math behind it if someone can explain it with a little less jargon. I bet it's actually really goddamn simple once you strip all that away and phrase it in plain english.

== About alternative location voting ==
 +
 
 +
After a (IMHO not very appropriate, since they mostly redefined geohashing to an event for their listeners) report about geohashing in swiss state radio I see an effect I don't really like. Just take a look at the graticule location maps for switzerland for today and yesterday, and you'll find that people try to shift the meetup locations to far away from the hash point to just a point in their neighbourhood, sometimes even over the graticule borders.
 +
 
 +
As I understand it, the feature to suggest an alternative location was meant for active graticules in case when the original location is inaccessible or for some other reason not useful at all, and that the alternative location should be nearest possible. I wouldn't feel comfortable with people shifting the location by half a degree into their favourite cafe and not even bothering to try to get somewhere, and then call it a success.
 +
 
 +
Btw: there are ten or more votes on graticules with zero members, but only one member joined the wiki by now...
 +
 
 +
So, I would suggest to add some more information to the maps, hoping that people will notice it there if they don't look anywhere else anyway...
 +
--[[User:Ekorren|Ekorren]] 13:31, 20 November 2008 (UTC)
 +
 
 +
:I don't have a problem with alternate locations that are far from inaccessible actual locations. For the purpose of the wiki, a meetup at an alternate is classed at [[:Category:Coordinates not reached]] and [[:Category:Failed - Did not attempt]]. The only respects that it counts as a success is towards the [[XKCD Centurion]] achievement, and that it made people happy. A graticule is big enough that one person's favourite cafe is going to be an interesting new discovery in a another place for another person. People do have to vote on it, and meet up, not just one person declaring a meet and going there. (Although the latter beats playing video games all day).

== Geohashing In Coastal Areas? ==
 +
Is there any official solution yet to geohashing in areas where most of the graticule is water? I recently moved from Manhattan to Singapore, and both locations have about a 5% chance of getting a viable point on any given Saturday. (I think Singapore's had a grand total of two since the kick-off in May.) This is mentioned in the issues page, but I didn't see anything about it here or on the archives. [[User:Adavies42|Adavies42]] 04:14, 27 December 2008 (UTC)
 +
:Yes: Wait and see. Geohashing never was about giving equal chances to all locations and participants, neither it can be. There are more geohashers who just wait for weeks and months until they find a point to reach! Try to reach a neighbouring graticule, wait for a point which is accessible, rent a boat for a waterhash, book a bicycle holiday in the Netherlands... whatever will be your way: If you make it, there will probably be much more to tell and to be proud of than in those graticules where a hash visit is done every few days. And your story ''will'' be appreciated. --[[User:Ekorren|Ekorren]] 08:15, 27 December 2008 (UTC)
 +
:Also, you basically -can- redefine the place for Saturday meetups if the rest of the graticule agrees. Some people in Australia agree to meet at the best hash from the last week during their Saturday meetup. Israel has considered redefining the shape of their graticule, to not include any (politically) dangerous territories, IIRC. These approaches make only sense for the meetup part of the game (where it's more about meeting people on a given time and date than reaching the actual hash, and where you can agree on such things), than for the hashing part (where it's more about waiting for a reachable hash to go there, independent of time and date). -- [[User:relet|relet]] 09:50, 27 December 2008 (UTC)

This wiki page has recently been a spam target. To effectively combat this, please use the "undo" function in the page history rather than deleting the spam outright. Spambots don't just add content, but delete legitimate content as well. If you just delete the spam, the net effect is a loss of content. Please use caution when restoring pages, and hold off on constructive edits if this problem persists.

Google Earth app

It would be interesting if we could somehow tie these pictures that people are uploading in with the google earth program- an app that lets you select a graticule, get a list / visual of points that have been geohashed, and retrieve pictures specific to those points. 70.162.29.88 20:14, 25 May 2008 (UTC)

I'm already generating a KML file that can be used in google earth (and maps) to look at active graticules. If there was a page listing all the images and where they should be placed, it would be trivial to include those images there as well. Zigdon 23:28, 25 May 2008 (UTC)
Since all of the pages for specific meetups have the same URL format, they could just be scraped off of the meetup pages- if the meetup page has that image on it, it gets listed for that location. There's probably an easier solution though...

Meeting Standards

In the case that the Geohash for the day falls in a crowded place or just for a conversation starter I propose a standard way of letting the "in" crowd know you are a geohasher, besides the obvious raptor signs etc. perhaps a red shirt or a Madagascar flag something for people to look for. --Ishboo 19:47, 3 June 2008 (UTC)

The Pinecone was the spot on 1st June, 2008 outside Canberra
How about the google maps red pin? Though more generally, I think if such a marker is needed, it can probably be pre-organised per graticule. --Nemo 22:30, 3 June 2008 (UTC)

When I was on my way to the hashpoint I wanted to have a secret sign and countersign so I could say, "Did you see the fish?" and if they were indeed geohashers they would reply, "the fish wears a hat," as opposed to the "Huh?" or "What fish?" replies one would expect from innocent bystanders.

Unofficial Invitations

Hey all, sorry for editing directly on the main page. I actually only wanted to change tomorrow's suggested meeting location, but couldn't drag it out of the graticule. Anyway, maybe others also like the idea. If not, feel free to remove it again. (After my summer solstice party tomorrow. ;) )

Sorry for the less-than-congenial grammar, I'm not a native speaker.

Gladstoning

I don't know the opinion of the community, but it feels like out of our topic here for me. Plus i don't like that it is without a signature. Sorry. --Tom 08:36, 21 June 2008 (UTC)

Listing elements of a category

Probably it is not the right place to ask, but i didn't find out where to ask. Is there a possibility to list the elemnts of a category on a page? I know i can link it, but is there a way to show it right there? Like... showing automatically the geohashers in my area on the graticule page based on the user category Geohashers_in_LAT_LON? --Tom 08:26, 2008-06-20 (UTC) (eh, one more question, is it possible to insert actual date and time here automatically?)

Just type ~~~~ (four tildes) to automatically sign your name and the current server time. I generally sign with two hyphens in front as well, e.g., --~~~~. You can also click the signature button (second from the right) above any edit window. --Tim P 13:29, 20 June 2008 (UTC)
As far as including the elements of a category, I know you can transclude the text of category directly onto the page by using {{Category:CATEGORYNAME}}, but I don't know how to include the elements, or even if it's possible. --Tim P 13:29, 20 June 2008 (UTC)
Thanks, Tim, but however i try, this {{Category:CATEGORYNAME}} stuff does not seem to do anything. Are these brackets okay? --Tomtom 21:50, 20 June 2008 (UTC)
Er, my name's Tim, but you're welcome anyway. :) Did you actually include the <code> and <nowiki> tags? Does the category actually have "text" in it, i.e., is it a blue link when linked to? That's the only way you can transclude the text; as I said earlier, I don't think that transcluding the elements is possible. Could you paste a specific example below, along with an explanation of what you're trying to do? Thanks. --Tim P 22:43, 20 June 2008 (UTC)
I'm really sorry. Your name's corrected.
I did not include code+nowiki, i thought i shouldn't if i wanted it to work. (Should I?)
Anyway. What i'm trying to do is this: A user can put the a/s/l template on his page. By doing so he's automatically gets a category, like "Geohashers in X, Y". I wanted to automate maintaining the local geohashers section of my X, Y graticule page by inserting a link to the category "Geohashers in X, Y" somehow to that place. I thought i could somehow make the wiki page show a list of the users in the category "Geohashers in X, Y" there, just like it does on the main page of the category. --Tom 23:07, 20 June 2008 (UTC)
I'm sorry; I must have misunderstood you. As far as I know, there's no way to transclude the elements of a category directly onto a page; i.e., you can't automatically list geohashers who have added the template on any page other than the category page itself. The only thing you can do is transclude the "description text" of the category, which wouldn't be very useful at all. Sorry! --Tim P 18:26, 21 June 2008 (UTC)
Yeah, i'm not a native english speaker, so the word transclude was not at all in my mind. I was just thinking that there's surely a way to collect the titles of the pages that contain the category template (? i don't know if template is the right word here, i mean [[Category:SOMETHING]]), just the way the category page itself collects them. (I mean, for example me and other users put [[Category:Geohashers]] to our userpage, and we are automatically being listed on the page of the category) I thought this listing can be programmed somehow similarly on an other page too. --Tom 12:34, 22 June 2008 (UTC)
(Of course i can believe that it can be impossible.) --Tom 12:36, 22 June 2008 (UTC)
Yeah, I'm pretty sure that's not possible, at least as this wiki is currently configured. Sorry. --Tim P 15:39, 23 June 2008 (UTC)

Front Page Coordinates

If I'm reading the front page source code correctly, I think that the front page's coordinates are generated automatically via a template...and that template doesn't seem to be working correctly! I get today's (2008/07/31, W of -30) coordinates to be .5356742, .4584283, but the front page differs. Is this a bug that needs addressing? --Scottkuma 14:41, 31 July 2008 (UTC)

Looks like. We had a problem at the end of June also - I think it's something to do with generating two sets of coords. --Thomcat 15:03, 31 July 2008 (UTC)
Corrected, but behind the scenes, as nothing shows up in RecentChanges. Thanks whoever! --Thomcat 16:18, 31 July 2008 (UTC)

Complete list of historical locations

Surely someone has by now generated a complete list of the decimal parts of the coordinates produced by the historical data? It can't just be me wanting to see it, can it? Does anyone have a link to one if so? Even better if it was available as a map overlay...

I put up a set of Historical Location Data that I generated a couple days ago. It seemed slightly too ginormous to put on the wiki in it's raw form, but if anywone wants to, be my guest. Unfortunately there are some bad dates in there due to Dow data that was missing, but I'll get them updated. My hope was to use the data to generate a map overlay or allow you to click a location on the map and have it show you all the dates that a geohash landed in the vicinity, but my web programming skills are nonexistent. I could write a Windows app, but that's not so great for anyone. Someone else tackle it. :) --ZorMonkey 11:57, 27 May 2008 (UTC)
I also have a set of location data 1970 to present for W30 and non-W30. No bad dates that I know of, generated using the Perl implementation today. I lack the google-fu to plot it on google maps, but am happy to provide it to anyone. Data is comma separated. And since I've got a domain name sitting around doing nothing, Ill put it to use: here 'tis free for any use --Psud 12:29, 27 May 2008 (UTC)
I've updated my non-W30 data, and added W30 data. Our numbers are pretty close, so that's good! 14,000 units tests passed! :) It looks like you're missing a few dates though - for example 2008-03-28. BTW - Mine is also in CSV format, and includes the DJIA so it can be used to calculate the numbers if anyone else is playing with the algorithm. --ZorMonkey 03:19, 28 May 2008 (UTC)
My data is now hole-less (Pls let me know if you find otherwise), and complete back to 1928-10-01 in both W30 and non-W30! download here! <-- Note also now in format date,DJIA,lat,long
Also now the data is available bzipped or text. My intention is to keep it up to date - updating at 03:00 my local time (GMT+10). Let's see if my scripting is up to it. NOTE: New web page
Wow, nice! With that I regenerated my Google Earth KML file for Milwaukee. It now includes different color markers for different days of the week, and each marker has it's date associated with it so you can use Google Earth's (frustratingly tiny) timeline to constrain the dates you want to show. I wish I had to good way to create a webpage that would generate a KML file for any region you wanted... Maybe I can attempt that this weekend - but probably not. :) --ZorMonkey 04:28, 29 May 2008 (UTC)
Can you just clarify for a st00pid n00b please - which of the "W30" and "non-W30" files should be used where in the world? Given that it's so far been "anyone east of W30 uses one, anyone west uses another" I don't know whether "non-W30" is east or west ;) ..... for reference, I spend much of my life between -1.5 and -2.1 degrees (1.5 - 2.1 west of greenwich :) - thanks Tahrey 15:40, 13 October 2008 (UTC)
See 30W_Time_Zone_Rule. Details on your User talk:Tahrey talk page.
Once you have one of the data files, it's pretty easy to generate a KML file for Google Earth. Google Earth freaks out a little bit, but it works! Here is a sample KML file (zipped) that I generated for the 4 graticules near the Milwaukee area, and the Python code I used follows. I've just started learning Python, so forgive any hackityness. In this state it needs to be manually tweaked to generate other graticule information, but it's pretty easy. Anyone know if it's possible to specify the marker color? --ZorMonkey 04:27, 28 May 2008 (UTC)
Instead of putting it here, I've put my increasingly terrible Python KML generating code up on the web. I'll update that file as I make changes and make it more (or less) awesome. --ZorMonkey 04:28, 29 May 2008 (UTC)
My python code is just like yours (I heared about python in the comics the first time). I used mine for generating a KML file for the Hamburg graticule. None of the placemarks are displayed except the ones mentioned in the corresponding wiki page (i.e. have expeditions). The template-like file "start" and the base-coordinates in the code should be edited, but then it shuould work on every graticule. I used Psud's list of historical coordinates. If my webspace was cool python-powered one, I'd like to set up a service, but it's a ceap on that doesn't allow outbound connections from PHP. --Hermann 15:12, 28 June 2008 (UTC)
Ha! I was wrong. Seems my provider loosened restrictions some time ago. I set up this script to generate KML-Data for any graticule. NOTE: This script uses Psud's list and caches output. Caches are updated every 24h. It's basically a proof-of-concept by now and needs testing.. Please have a look on the code, improve it and/or move it onto your webspace to reduce mine's traffic.
I worked on it a few hours and it has become pretty elaborate. Check it out or have a look at Hamburg for an example. --Hermann 00:22, 30 June 2008 (UTC)
Unfortunately, Psud's lists are down. The service is now defunct. --Hermann 13:38, 2 July 2008 (UTC)
UPDATE: Psud fixed his server. The Service is up and running. Comments please. --Hermann 22:20, 3 July 2008 (UTC)
I have generated KMZs for the Cincinnati, Ohio and Detroit, Michigan graticules. Each are linked to off of the respective graticule pages. Scottkuma 19:35, 30 May 2008 (UTC)
Hmm. So, if I generate this historical data, and one (or more!) points in the past land on my property, do I qualify for the Time Traveller Couch Potato GeoHash Achievement ?? --Briand 18:29, 6 June 2008 (UTC)
Well, if you do supply proof of date and location (i.e. standing in your living room next to a calendar showing that particular date), you will sure apply for the award. --Hermann 10:44, 1 July 2008 (UTC)
I think it would be very nice to see the pattern of all historical locations within a graticule. Do you think it is possible to make it? Will they be random markings, or will they show some disparities? I am very curious. (Just don't think i can make it soon.) --Tom 19:59, 12 August 2008 (UTC)
The sample KML file (zipped) from above contains the historical locations for 4 graticules, which will show any patterns there may be including any bunching/receeding at the edges. I can't see any pattern to it myself but there's a whole lot of data. Don't forget to change your time span settings in Google Earth if you want less/more points. -- Moose Hole 20:09, 12 August 2008 (UTC)
Thanks. I will check it out. --Tom 14:21, 13 August 2008 (UTC)
Pleas also chek out my service. You can find an example at my profile. --Hermann 20:38, 16 August 2008 (UTC)
Thank you for your service. I like it! I tried it for graticule 49_8. The co-ordinate for 2008-11-28 differs from the one at http://irc.peeron.com/xkcd/map/map.html?date=2008-11-28&lat=49&long=8&zoom=8 (other graticules probably, too). I found that one accidentally as I visited 2008-11-28_49_8. Did anyone find other data errors? --Fluxkompensator 16:20, 23 June 2009 (UTC)

Slow to load, impossible to edit

The main page seems slow to load anymore, and it is difficult to edit sections. I've tried multiple times to add to the date section today, but all those submissions crash and burn. I know it's Friday, but it's been slow other days also. Is it just me? --Thomcat 21:22, 18 July 2008 (UTC)

No, I noticed it, too, around July 10th and 11th. -- Jevanyn
Slow for me too. I was thinking it was some special mechanism because it was the main page, or something. -Robyn 00:04, 24 July 2008 (UTC)
Tried four submits just now, and a few times on Friday, to update the coordinate table on the main page. Each failed. --Thomcat 13:15, 11 August 2008 (UTC)

Spam

Seems like a few pages are taking the brunt of the hits. Clearly it/they seem to be watching those pages. Is any of that through the "watch this page" checkbox mechanism? Can that link be blown away somehow? I'm pretty new at this, but I know we need to find a solution other than banning the various IP addresses, and {protected} doesn't work on those pages. --Thomcat 19:11, 21 July 2008 (UTC)

I've made a copy at Talk:Main Page/Archive3 (no space). The Archive template could be modified to point to no-space pages if necessary. I suggest somebody admin attempts deleting that page, so we can see if the spam stops arriving there. --Thomcat 23:51, 23 July 2008 (UTC)

Can we put it to a vote, to require registration to post? Spam activity seems to be increasing, and attacking different pages than before. Also, isn't there a template or other method to protect pages? -- Jevanyn 14:00, 15 August 2008 (UTC)

Mother Nature vs. The Internet vs. Civilization

I would really love to see a score table

Mother Nature vs. The Internet vs. Civilization

sorting all the hashes into

  • failed because of weather and/or landscape
  • successfully reached
  • failed because of man-made obstacles (fenced in, no trespassing, failed GPS devices and the like).
  • (any other reasons? laziness would account for a draw IMHO.)

However that would mean to parse through all past expeditions and classify the expeditions.

What do you think of the idea? Could it be realized to remain easy to maintain, when adding future expeditions - use Categories maybe? Would you be willing to help? -- Relet 00:54, 27 July 2008 (UTC)

Cool idea. I'd be willing to reclassify mine. You can see reasons I have failed on my user page. The extra category should encompass laziness, chickenness, and our own errors. Data collected based on hash reports would, however, leave out the geohashes never attempted because it was obvious that mother nature or civilization would win the day: in my graticule that's all the ones on glaciers or mountains, or in the protected watersheds. - Robyn 05:34, 27 July 2008 (UTC)
I agree with Robyn, and definitely use categories. I plan to go through them all to classify the difference between Category:Expeditions and Category:Expedition planning, which will eventually lead to an automated expedition counter. I would gladly add other categories - please suggest here! --Thomcat 15:07, 31 July 2008 (UTC)
Ok, great. I suggest something like Category:Defeated by Mother Nature, Category:Successful Expedition, Category:Defeated by Civilization (any capitalization rules in this wiki?).
These should only be used for actually attempted expeditions. I don't think that it makes sense to include non-attempted expeditions. Unless there was a rule which requires The Internet to make a move every saturday, it isn't a fair game for the other two anyway. Not reporting a failed expeditions is just bad style (and people want to show off anyway). -- Relet 15:42, 31 July 2008 (UTC)
Hmmm, definitions time. An "expedition" is when people set out to attempt a geohash (or meetup). I like "defeated" but it's a little wordy, and don't want to tie it to the expeditions. Nature can nearly always be beaten, given time, money, and effort. How about Category:Coordinates Reached, Category:Coordinates Restricted and Category:Coordinates Unreasonable? I tried unreachable, but that covers restricted as well. --Thomcat 17:04, 31 July 2008 (UTC)
Additional - Category:Coordinates Unknown covers the weekend we had coordinate problems (May 31) and a few others where people made an expedition without a GPS and reported they weren't sure if they made it or not. Any other discussion on these categories? --Thomcat 00:28, 2 August 2008 (UTC)
I like the wordy version better, since it goes along the Mother Nature meme. I don't mind another wording, though. Coordinates Reached and Coordinates Restricted are clear to me, but "Unreasonable" does not bear the same message (the failure having natural causes). IMHO, that would include expeditions which weren't attempted in the first place. My idea was to separate into success/man-made obstacles and failures/failures caused by force majeure; natural causes. But maybe we can just separate into Success/Failure in a first step, and then see whether to further classify the failures.
Not knowing your coordinates / failing GPS / relying on your memory of Google Maps is a human failure IMHO. ;)
Nature can "always be beaten", if you're prepared for everything. But she's good at catching you off guard. Just think of the raptors. And you've only got a few hours-days for preparation, depending on when and where to go. -- Relet 23:00, 2 August 2008 (UTC)

Project underway. Going with Category:Coordinates reached and Category:Coordinates not reached, and then in the latter case, adding one of Category:Failed - Mother Nature, Category:Failed - No public access, Category:Failed - Technology, or Category:Failed - Did not attempt. --Thomcat 16:43, 4 August 2008 (UTC)

Caveats - I use the best possible category, i.e. if some gave up but other succeeded, that counts as success. Proven non-public areas will nearly always be failures, unless somebody qualifies for Restricted Area Geohash or the like. Finally, if the spot is within error for the GPS (less than 10 meters usually) but unreachable, that's a success - it's happened to me twice. --Thomcat 16:43, 4 August 2008 (UTC)
Further caveat - I will leave comments where I have to make some sort of judgement call. --Thomcat 18:00, 4 August 2008 (UTC)

Project nearing completion. Last post here. Scorecard through July 31st:

  • 335 expeditions with coordinates reached successfully
  • 123 expeditions brought up short by private property restrictions
  • 69 expeditions foiled by Mother Nature

--Thomcat 17:24, 12 August 2008 (UTC)


Numerical graticule redirects...

I'd like to propose that each graticule have a page named for the graticule's numerical coordinates. For example, I've created a simple page for Cincinnati, OH at 39 -84 that is a trivial wiki redirection to the main Cincinnati, Ohio graticule page. In this way, it becomes VERY easy to write coordinate maps that link to adjacent areas, and it also becomes easier to computatively traverse coordinates to see what is available. Any suggestions/comments? -Scottkuma 16:07, 4 August 2008 (UTC)

I always thought that to be the convention already. Support, but with a comma and no spaces, as in 39,-84. :) -- Relet 16:08, 4 August 2008 (UTC)
Is there a location where these conventions are laid out for all to see? (excuse my ignorance, pls!) -Scottkuma 16:11, 4 August 2008 (UTC)
Better than a lot of redirects could be ... a template (e.g. graticule 39 -84). The template could do the lookup on the All Graticules page to display and link to the name. I have too little experience with templates to know if this is impossible. --Thomcat 16:26, 4 August 2008 (UTC)
Yes, this is already done on an as-needed basis for the ASG template. Generally, inactive graticules do not have this redirect because it is unnecessary. If you want to code something to traverse graticules, try traversing using the All Graticules page. -- Moose Hole 17:21, 4 August 2008 (UTC)

Seconded. The convention for such redirect pages has been to use a comma and no spaces, influenced entirely by Template:ASG, which was the first feature to require such redirects. If you want to create a system of such pages to facilitate the inclusion of neighboring graticules, go for it! --Tim P 18:38, 5 August 2008 (UTC)

Front page galleries very slow to refresh

I've noticed that the Gallery of Recent Expeditions is exceptionally slow to update. Is there any good reason for this, and is it to be fixed? --Psud 13:38, 5 August 2008 (UTC)

The pictures are manually added, so they don't update until someone (a) goes on an expedition and (b) chooses to show of his or her pictures. They load quickly for me, so this is my guess at what you meant, even though it's not what you said. Relatedly, I notice that the Upcoming Coordinates for Tuesday W haven't updated yet, though, even though they have been available for fifteen minutes. - Robyn 13:47, 5 August 2008 (UTC)

I think Psud means that he adds a picture, and it doesn't show up on the main page, even if he does a CTRL-F5. I've noticed that also. The pictures are running through a template, which (I'm guessing here) is connected to a database. They've always shown up within a few minutes for me, though. --Thomcat 14:19, 5 August 2008 (UTC)
As far as MediaWiki is concerned, there is a good reason for this... caching. In order to reduce server load, complex templates are cached and are only reloaded/recalculated when an edit to the page housing that template is made. However, there is a little known "purge cache" workaround that will force the server to regenerate the page if you want. Simply add the code [{{fullurl:{{FULLPAGENAME}}|action=purge}} Refresh the cache] to any page to add a link which will purge the page's cache. I've added this code to Main Page already, as I'm sure this is where it is most wanted/needed. --Tim P 18:35, 5 August 2008 (UTC)

Automation of Coordinates Box

I have been doing some work in attempting to automate the coordinates box for the Main Page. You can see it in my sandbox. The problem I'm having is that I know how to make it happen, I just can't get the Wiki to actually make it happen. Once I try to get it to display more than four lines of data in the table it seems to freeze up the Wiki. I'm guessing it is something to do with there being too many if statements or template call-ups.

I have successfully automated the table without a colspan=2 effect for the weekend coordinates, but it just doesn't look as slick as having that effect in there.

Does anyone have any suggestions? Or know why this is occurring? --CJ 06:34, 26 August 2008 (UTC)

Devices used?

I'm curious to what devices you all use to find your location. Pure GPS devices? Phones? iPhones? Computer print-out? --Timma 02:47, 6 September 2008 (UTC)

  • My navigation is based on maps, high zoom satellite photo prints, and sometimes a compass. --Tom 17:47, 3 September 2008 (UTC)
  • OpenMoko Freerunner (an open source Linux PDA/Phone-thingy) with various kinds of mapping software. I'm currently stuck with tangoGPS because it uses the beautiful (and extremely accurate, and free) maps of the OpenStreetMap Foundation. -- Relet 09:13, 6 September 2008 (UTC)
  • I'm using a Garmin GPSMAP60Cx. You can check out expeditions, they usually have a picture of a GPS, most often one of the outdoor devices from Garmin(GPS(MAP) or eTrex) or Magellan.--Arvid 09:24, 6 September 2008 (UTC)
Here's a page commemorating our various GPS Receivers, mostly just photos. -Robyn 16:36, 18 September 2008 (UTC)

The Day I Was Born

I think it would be super cool to find out if anyone was actually born, at that day's hash point. That would deserve a very awesome ribbon. --Kate 10:42, 5 September 2008 (UTC)

The first thing I did when I found this was to check where my birthplace location was, great idea. --Timma 02:49, 6 September 2008 (UTC)
Historical data, and I believe there's at least one mapping implementation out there that goes all the way back to the beginning of the DJIA. --Psud 15:12, 3 December 2008 (UTC)

in need of some help

about my regional geohashing challenge, i'd like to calculate the percentage of the area that is inside the chosen region in every graticule. could somebody please help me to find a way to do that? i was thinking about, like, drawing the graticule rectangle and getting its area, and drawing the polygon of the region and getting its area. is there a way to do this in google maps or somewhere? i know google maps can tell you a lenght of a line, but is it possible with areas? --Tom 09:17, 9 September 2008 (UTC)

For the Kekerengu, New Zealand page, I used this Google Maps extension to calculate the land area (since it was small enough), and Geotudes to find the area of the graticule as a whole. After a few conversions, I got some pretty interesting numbers; certainly enough to fill a graticule page! --Tim P 13:25, 16 September 2008 (UTC)
wooooh. that's perfect, thank you. one more question: how did you check all the historical hashpoints? is it possible to make a database of them somehow? --Tom 17:55, 18 September 2008 (UTC)
Databases already exist all the way back to the DJIA. My example --Psud 15:16, 3 December 2008 (UTC)

Shifting coordinates

For some reason I have noticed that of this week (and possibly earlier?) if I check the coordinates within an hour or so after they are released they give me one certain point for that day's hash location, and then if I check again a few hours later they have changed to generate a different point for the same day! What is going on here? Has anyone else who noticed this? (It may be a problem specific to people only east of -30) --CJ 23:05, 18 September 2008 (UTC)

I had the same problem while doing planning this morning. Doc Wilco told me on IRC that when the markets first open some values are not known, only estimated and that the number is adjusted for a little while. Perhaps the extreme shakeup in the markets recently made that go on longer than usual this morning. You know you're addicted to geohashing when your first concern in a major market collapse is that the day's coordinates will be late. -Robyn 00:04, 19 September 2008 (UTC)

Hahaha...I know exactly what you mean! I too thought it may have had something to do with the state of the stock market at the moment (and inside my head a voice is saying How am I expected to geohash if the market is messed up! It happened to me earlier in the week too, but that night I had a very vivid dream about geohashing, so when I woke up I figured that the coordinates that I thought I originally saw must have just been in the dream. It's scary, I've now had two vivid dreams that I've been geohashing...--CJ 00:57, 19 September 2008 (UTC)
Okay, so the question be this. How long do we have to wait until the coordinates "settle down" for a given day? I've got geohashing to plan, and no scurvy dog bank dare get in me way. Don't make me call out the Crimson Permanent Assurance! --Thomcat 13:18, 19 September 2008 (UTC)
Hard to say. I'm an investor and actually pay attemtion to the stock market, so I'd imagine any pre-9:30AM EST estimate is based on the estimated opening price of the Dow components, which have been changing (ok, plummeting) quite a bit lately. Monday will be particularly interesting, as one of the component stocks is being replaced by another company. -- Jevanyn 13:32, 19 September 2008 (UTC)
Does anyone know what is happening? The weekends locations were supposed to be up 2 hours ago. Oh dear, I think I am addicted to geohashing. Kate 15:46, 19 September 2008 (UTC)
Seems like irc.peeron.com has problems getting the finance.google.com DJ data. I looked the DJ value up manually, used the Semi-Manual Offline Calculator to get the coordinates and planned my bike tour for Saturday accordingly. Later, I will check if peeron works again, just to make sure. Danatar 16:05, 19 September 2008 (UTC)
Hooray! Peeron is now up and running! (and the coordinates ARE completely different to what they were 5 minutes ago...)--CJ 16:06, 19 September 2008 (UTC)
Hmm, if the market does crash then just plonk the date into the algorithm and have the next.. however long's co-ords...hmm
In general, Peeron should have the data by 9:30am Eastern time. It does do another check at 10am so that if google changes it's mind as to what the opening values are (as has happened at least once before), we can keep up. Other than that, the values should be static unless I update them manually for whatever reason. If something seems weird, I'm always available in the IRC channel (#geohashing on irc.xkcd.com), or just write something on my Talk page. Zigdon 23:15, 13 October 2008 (UTC)
I don't suppose today is some kind of US holiday to do with the election is it? --CJ 13:48, 3 November 2008 (UTC)
I think you may have forgotten to take Daylight Savings Time into account. --Thomcat 14:41, 3 November 2008 (UTC)
Yep...that'd be it. Our daylight savings (here in Australia) kicked in a month ago. Had forgotten that yours only just did. Wow - that now means that the wait for co-ordinates has gone from 11.30pm to 12.30am to now 1.30am. Dont think I'll be staying up to wait for them anywhere near as much now...--CJ 22:48, 3 November 2008 (UTC)

a few questions - graticule map, accuracy required, geotudes

Hi.... just some stuff

1/ the "online map of active graticules" seems a little out of whack, it doesn't include my fairly active home graticule, but does have a neighbouring and decidedly dead one listed and clickable. Is there any way we can edit it, suggest updates, etc?

It's a wiki, you edit what you know, so go for it. Consult Creating a Graticule Page for instructions, and leave me a message if you have any trouble. -Robyn 13:18, 13 October 2008 (UTC)
It parses the site All Graticules list once per week. -- Relet 13:21, 13 October 2008 (UTC)

2/ what sort of absolute accuracy will be accepted in terms of a geohash success/fail? EG my main method of quickly checking up on them at the moment is an old copy of Autoroute (as there's no internet wait times, and it can easily remember a huge number of pushpins without any of google maps obtrusiveness) - but this only goes to an accuracy of 4 decimal places after the graticule degree, which in my area translates to something like a 10x20 metre square... is it enough to figure out I'm somewhere within that square (no GPS right now either - i'm a poor scrub!) and provide photographic proof of such that can be checked against aerial photos? most of the nearby locations that have come up so far are fortunate enough to have been in an open field next to a half decent road, so if anyone was there, or if a marker had been left, they/it wouldn't be difficult to see & shout to/find & add to.

If you have achieved good faith accuracy to the best of your technology, no one is going to complain about your claim of success. It's not like there are prizes beyond your own sense of satisfaction. -Robyn 13:18, 13 October 2008 (UTC)
There are no rules per se. If you feel you're *there*, it's usually good enough. More specifically, a 10m GPS error range is considered acceptable by most hashers. Also, if you are in a situation where you easily could have come closer, but common sense tells you not to (e.g. trampling flower beds or fields) it's ok. If there is a big fence between you and the spot you identified, your feeling will tell you it's a FAIL. -- Relet 13:21, 13 October 2008 (UTC)

3/ ok, i'm no maths genius, but fairly competent and took it til age 17 at school. But I can't understand half of what's going on with that GeoTude page. I get the concept but their formulas confound me - what's all this "Floor", and alpha/beta business? I know it's a seperate site but they have no contact details whatsoever, and I've seen at least one page here where someone describes an area using those co-ords. I know it'd be a useful tool and they have an online converter anyway, but I'd prefer to actually understand the math behind it if someone can explain it with a little less jargon. I bet it's actually really goddamn simple once you strip all that away and phrase it in plain english.

I'm not sure, which formula you're referring to exactly. The floor() function returns the next lower integer value of a real number, i.e. floor(3.1415)=3. -- Relet 13:27, 13 October 2008 (UTC)

oh, also, my FP, yay(?) :-S Tahrey 13:07, 13 October 2008 (UTC)

P.S. Create a user page. :-)

About alternative location voting

After a (IMHO not very appropriate, since they mostly redefined geohashing to an event for their listeners) report about geohashing in swiss state radio I see an effect I don't really like. Just take a look at the graticule location maps for switzerland for today and yesterday, and you'll find that people try to shift the meetup locations to far away from the hash point to just a point in their neighbourhood, sometimes even over the graticule borders.

As I understand it, the feature to suggest an alternative location was meant for active graticules in case when the original location is inaccessible or for some other reason not useful at all, and that the alternative location should be nearest possible. I wouldn't feel comfortable with people shifting the location by half a degree into their favourite cafe and not even bothering to try to get somewhere, and then call it a success.

Btw: there are ten or more votes on graticules with zero members, but only one member joined the wiki by now...

So, I would suggest to add some more information to the maps, hoping that people will notice it there if they don't look anywhere else anyway... --Ekorren 13:31, 20 November 2008 (UTC)

I don't have a problem with alternate locations that are far from inaccessible actual locations. For the purpose of the wiki, a meetup at an alternate is classed at Category:Coordinates not reached and Category:Failed - Did not attempt. The only respects that it counts as a success is towards the XKCD Centurion achievement, and that it made people happy. A graticule is big enough that one person's favourite cafe is going to be an interesting new discovery in a another place for another person. People do have to vote on it, and meet up, not just one person declaring a meet and going there. (Although the latter beats playing video games all day).
And it's Switzerland: not everyone is an alpine mountain climber! You have to cut them a break. If used the "nearest accessible point" rule in my graticule, we'd forever be meeting in front of the locked gate the gate to the watershed access road.
On the topic of not joining the wiki, I discovered that some friends of mine went geohashing without ever using the wiki. They had downloaded the iPhone app. Perhaps the maintainers of such apps could point people back to here. -Robyn 16:47, 3 December 2008 (UTC)

Geohashing In Coastal Areas?

Is there any official solution yet to geohashing in areas where most of the graticule is water? I recently moved from Manhattan to Singapore, and both locations have about a 5% chance of getting a viable point on any given Saturday. (I think Singapore's had a grand total of two since the kick-off in May.) This is mentioned in the issues page, but I didn't see anything about it here or on the archives. Adavies42 04:14, 27 December 2008 (UTC)

Yes: Wait and see. Geohashing never was about giving equal chances to all locations and participants, neither it can be. There are more geohashers who just wait for weeks and months until they find a point to reach! Try to reach a neighbouring graticule, wait for a point which is accessible, rent a boat for a waterhash, book a bicycle holiday in the Netherlands... whatever will be your way: If you make it, there will probably be much more to tell and to be proud of than in those graticules where a hash visit is done every few days. And your story will be appreciated. --Ekorren 08:15, 27 December 2008 (UTC)
Also, you basically -can- redefine the place for Saturday meetups if the rest of the graticule agrees. Some people in Australia agree to meet at the best hash from the last week during their Saturday meetup. Israel has considered redefining the shape of their graticule, to not include any (politically) dangerous territories, IIRC. These approaches make only sense for the meetup part of the game (where it's more about meeting people on a given time and date than reaching the actual hash, and where you can agree on such things), than for the hashing part (where it's more about waiting for a reachable hash to go there, independent of time and date). -- relet 09:50, 27 December 2008 (UTC)
