wow! everyone was just silent after the "revolution". no one said a single word about the right-wing armed forces. now the news are back in the front page of HN, cool... and meaningful in terms of timing, as one of those politics guys says in my country.
You should allow apps downloaded from places other than App Store. Go to Security & Privacy under System Preferences, and on the general tab, select "Anywhere" under "Allow apps downloaded from:" option.
When you have some slow peers along with a lousy internet connection, put.io really helps. with my upload speeds (makes 56K jealous), to seed a torrent up to a meaningful ratio, i should wait forever. put.io helps me with this and many other stuff. besides that, they recently added a server to my city, which boosted my usage.
Besides the torrents, they catch rss feeds, podcasts faster than I do, and I just stream it, if I need any subtitles, I just upload them (or fetch from open subtitles) and there they are.
I love their service and will keep supporting them, and recommend to anyone I know.
