Re: [HOT] Map-a-thon getting 509 Bandwidth Exceeded error

[Nicholas Doiron]

Hi Mikel,

I sent the IP address to the osm-dev IRC chat about 24 hours ago. Maybe
someone can dig it up?

I should note that I was running an app to review our users' changesets and
count features added. This may have pushed us over a short-term throttling
limit, but not the longer-term daily limits.
https://github.com/mapmeld/osm-scorekeeper

There are three more organic factors which affected our downloading:
- our new mappers panned and zoomed over a large area, downloading more data
- our area is dense with buildings data
- our area has many Mongolian gers, which are circular ways

I was under the impression that people *can* request a reset, if an admin
is online, but admins currently can't schedule or whitelist IPs ahead of
time.

If there's anyone who would look over the C++ for the rate limiter

and explain it to a web-stack developer like myself, please contact me
off-list.

Yes, this is probably due to a shared IP address for that lab. This problem has 
been seen before at mapathons, but usually with much higher number of users. 
Usually, the rate-limiting will ease off after a time, so it should've been 
available again later.
The OSMF Operations team won't currently make exceptions to the rate-limiting 
policy. But they do think it should be an unusually high volume situation to 
trip the bandwidth limits. I think it's worth asking if one of them will 
investigate more closely to see if there was something unusual in the situation 
of your mapathon. Do you have the IP address for the mapathon venue?

 Hi,
I'm working with The Asia Foundation to run an OpenStreetMap map-a-thon in 
Ulaanbaatar, Mongolia. We have 17 teams of 3 people, mostly students and city 
planners, mapping unplanned areas of the city (ger districts)
At 3:30pm local time, we got a 509 Bandwidth Exceeded error on most teams' 
machines, so we had to end our first day early.  No one's data is lost, but we 
can't download existing data into iD, so every map area looks blank.  There was 
a risk we would add the same building many times.
Is there a way for us to re-enabling editing before tomorrow morning? And keep 
the gates open for another 48 hours or so?I'll do my part by closing a couple 
of apps (including Show Me The Way from OSM Labs) which were running at the time

Re: [HOT] zebra crossing

We found a in #1047. It was a node of building. They seem to be Easter Eggs. 

"An Easter egg is an intentional inside joke, hidden message, or feature in an 
interactive work such as a computer program, video game or DVD menu screen."

Re: [HOT] zebra crossing

[Bryan Housel]

Hi John,
I’m happy to change the preset in iD to make it more clear.   Maybe we should 
just offer 2 presets that differentiate between “Marked Crosswalk” (aka 
`crossing=zebra`) and “Unmarked Crossing”?

This is an odd one because “Zebra Crossing” seems to be a well known thing in 
British English, but is unknown in American English.  In the United States 
people were asking me for a crosswalk preset, and we saw new mappers skipping 
crosswalks entirely because they didn’t know that `crossing=zebra` was the 
correct thing. Also, at the time the OSM wiki was confusing - it seemed to 
imply that all crossings were zebras - not sure if that is still the situation.

Thanks, Bryan

Re: [HOT] zebra crossing

You are indeed right John, if you select a node belonging to a highway the
crosswalk element appears in the tagging list. The result gives you an
element with both highway=crossing and crossing=zebra tags.

That's what is being tagged.  Quite often on paths or footways or even
tracks in very remote parts of the world.  I've seen maybe four in West

[HOT] zebra crossing

[john whelan]

I'm seeing a number of these on different projects.  They could be put in
for fun but I suspect there are too many,they seem to come from
inexperienced mappers I suspect using iD.

A possible undocumented feature or too easy to add? There seems often to be
two tags involved on the node which would be unlikely if it was done for
fun.

Thoughts?
