Re: [OSM-talk] SHA-1 collision announced by Google

It's been known for a while that sha1 can generate duplicates. What next
the announcement that MD5s have collisions too?

All hashes by their nature can have collisions. The news is there is a 
practical way to intentionally generate them. It's the first time this is done 
for SHA-1, at least publicly announced (it wouldn't surprise me if the NSA had 
secret techniques and computing power to do it already).

The only one that wouldn't have collisions would be to hash every single
bit to produce a 1:1 copy of the file(pretty useless) or bigger. So yes all
hashes can create collisions, its more on the probability that it happens
to be as low as possible

[OSM-talk] iD is getting a new menu...

2017-02-25 Thread Bryan Housel 
Just wanted to pre-announce that the next version of iD (coming sometime in 
March) will have a new menu!
Here’s a picture:  https://twitter.com/bhousel/status/835607333640232962 


We don’t often change iD’s user interface, but we felt that iD was starting to 
outgrow the “radial menu”, and it was time to move to a more traditional 
right-click context menu.  The new edit menu will only pop up when the user 
right-clicks, so it will not get in the way of editing as much as the old menu 
did.  Also by switching from a circular shape to a vertical bar, we are less 
constrained by the number of items that we can add to the menu.

Details about how the work came together over the past month, and screenshots 
can be found here:
https://github.com/openstreetmap/iD/pull/3753 

Thanks to Kushan for much of the code, and Rasagy for the design work.

Please try out editing with the new menu by using the mirror here:
https://openstreetmap.us/iD/master/ 

Thanks,
Bryan
