Square Reader SDK lets you use Square hardware to take payments in your app.
Here we go again, for the month of October to date:
Something I don’t get: out of the 9,883 unique IPs for Safari, 1,282 are already using Panther’s Safari update. In other words, 13 percent of Daring Fireball readers who use Safari were already using Panther before today. That seems awfully high. It’ll be interesting to see how high that number jumps in the next week.
Note on Methodology: It is not possible to accurately count “unique visitors”. What I do is count each originating IP address once for each browser. This means that if you’re using DHCP and get a new IP address from your ISP, you’ll get counted multiple times. Similarly, multiple visitors coming from behind the same proxy or router (like if you have several machines sharing a cable modem connection at home) will only be counted once, because in the logs they’re sharing a single IP address. The point is not to count readers, but to gauge the popularity of various browsers.
