Sorry! I realized I should've added some caption to the figures.
- In the two histograms are the distribution of the age of Tor versions.
Most people have their Tor between 0 - 250 days old and there is a
- In the box plot, the boxes contain the first quantile to the third
quantile of data points, and the line in the center is the median. The
upper and lower "whiskers" show the maximum and minimum of the data, and
the points above the top whisker are outliers. It appears that there are
less bridges with very old versions, but the bridges and relays are similar
in keeping up with new versions.
You're definitely right that the temporal changes are important. I'll focus
on this in some follow-up analysis. I have a couple of questions regarding
1. What is the "date" column in the csv file you shared, specifically?
2. What's a good way to see the the unattended updates data? I can look
into it if you could point me to a general direction.
3. It seems many of the potential questions will require new data. I'm
happy to work on data generation/cleaning; but is there a good way to share
the datasets or figures? They may also be too large for the mail list..
Hi Teor - thank you for chiming in! The release schedule page looks
awesome. I notice there is not any mention of dev versions - is that
information also available somewhere?
