1 00:00:00,003 --> 00:00:04,617 Now I am going to do a short example of cognitive walkthrough on a non-related piece of software 2 00:00:05,115 --> 00:00:06,905 just to give you an idea of what we are looking for. 3 00:00:07,644 --> 00:00:10,951 So the task I have for this cognitive walkthrough 4 00:00:11,547 --> 00:00:15,108 is to open a painting program and draw a red hexagon. 5 00:00:16,469 --> 00:00:19,010 So I am looking at the screen right now. 6 00:00:19,010 --> 00:00:21,310 I am trying to see what options are available to me. 7 00:00:21,310 --> 00:00:25,407 Nothing looks like it is exactly a painting icon. 8 00:00:25,407 --> 00:00:27,934 So I'm not exactly sure where to click. 9 00:00:27,934 --> 00:00:33,853 I probably would go for this, but on second thought, 10 00:00:33,853 --> 00:00:38,283 I want this magnifying glass because that usually gets me some results. 11 00:00:39,054 --> 00:00:40,740 Let's try "paint". 12 00:00:42,167 --> 00:00:44,930 And that looks like pretty likely so I am going to choose that one. 13 00:00:48,886 --> 00:00:50,771 All right, now it is asking me, 14 00:00:50,771 --> 00:00:53,448 it looks like its asking me how big it wants the image to be. 15 00:00:53,448 --> 00:00:57,130 I'm wondering at this point whether I will be able to change this decision later. 16 00:00:57,130 --> 00:01:02,396 It doesn't say whether I will be able to undo this, but I think that what it is will be fine. 17 00:01:02,396 --> 00:01:05,260 So I'm just going to ignore that and click okay. 18 00:01:07,016 --> 00:01:09,947 And the window changed size. I assume that means it changed to the size that I just entered. 19 00:01:11,686 --> 00:01:16,388 All right, so I need to make this red. This definitely looks like color selection so I will try that. 20 00:01:18,299 --> 00:01:21,085 It is giving me a bunch of options for color. 21 00:01:22,521 --> 00:01:26,962 "Strawberry"... is not quite what I want. 22 00:01:26,962 --> 00:01:28,653 Maybe "Maraschino". 23 00:01:29,311 --> 00:01:34,090 Now, I am seeing if there is a tool that will draw shapes like a hexagon. 24 00:01:34,826 --> 00:01:39,545 This says "Rectangle" and if I click on it, it looks like it is only rectangles. 25 00:01:40,188 --> 00:01:44,855 "Ellipse". That's no good. "Rounded Rectangle"? 26 00:01:45,417 --> 00:01:47,980 So I think I might have to draw my own hexagon. 27 00:01:48,441 --> 00:01:51,213 I am going to click on a paintbrush. That's the tool I want to use. 28 00:01:51,213 --> 00:01:54,655 No, wait! The line tool is better. 29 00:01:55,106 --> 00:02:01,245 All right, so I am going to draw a line by clicking and going over here and click again. 30 00:02:01,245 --> 00:02:04,438 And... that's not what I wanted. 31 00:02:04,819 --> 00:02:07,688 So, I was expecting it to draw a line between those two points but that didn't happen. 32 00:02:08,233 --> 00:02:10,758 So I am going to undo that. 33 00:02:11,889 --> 00:02:14,843 And this time, I am going to try dragging. 34 00:02:14,843 --> 00:02:17,750 Okay, and that does what I want. 35 00:02:17,750 --> 00:02:21,855 So, okay, I got the hang of this. This is pretty easy. 36 00:02:22,409 --> 00:02:26,830 I wonder if there is a way to auto-close this shape, but I don't feel like actually looking for it, 37 00:02:26,830 --> 00:02:29,427 so I am just going to manually link this up. 38 00:02:31,063 --> 00:02:37,413 And now, I know from other paint programs that usually a paint bucket will fill something in, so we will try that. 39 00:02:37,413 --> 00:02:40,620 Okay, and that did what I expected. It filled in the red area. 40 00:02:40,620 --> 00:02:43,973 All right, so that's a cognitive walkthrough. That's an example of how we're going to do it. 41 00:02:45,068 --> 00:02:49,740 Now I'm going to ask you to do another demonstration. This one will not be using the software that we're testing. 42 00:02:50,324 --> 00:02:53,185 Oops. That's not what I expected. 43 00:02:55,271 --> 00:02:58,474 But just to let you have practice at doing this. 44 00:02:59,021 --> 00:03:06,981 So your task is to use a web browser and find out the population of Zimbabwe. So go ahead. 45 00:03:07,862 --> 00:03:12,794 Looking at the desktop, I see the common ribbon across the bottom 46 00:03:12,794 --> 00:03:17,700 with two popular web browsers, Saf—, Chrome and Firefox. And I am a die-hard Chrome addict, 47 00:03:17,700 --> 00:03:20,712 so I double-click Chrome to launch that. 48 00:03:22,104 --> 00:03:27,193 Chrome is prompting me to sign in and this isn't a computer I trust, so I'm not going to sign in. 49 00:03:27,193 --> 00:03:38,147 Instead in, I am going to type in the URL bar, "https slash slash google dot com". 50 00:03:38,147 --> 00:03:40,257 I like to run all of my searches over— 51 00:03:40,257 --> 00:03:46,375 Oh, and I get as far as typing in "https g", and the browser selects, or, suggests Google for me, 52 00:03:46,375 --> 00:03:49,060 so I am going to take that suggestion. 53 00:03:49,060 --> 00:03:57,762 I now have the search bar in the middle and I type in "population of"... 54 00:03:57,762 --> 00:04:03,284 And I get as far as typing in "population of zi" and it selects "population of zimbabwe". 55 00:04:03,284 --> 00:04:08,248 I am going to go with the "I'm feeling lucky" suggestion, not even letting it complete the year, 56 00:04:08,248 --> 00:04:14,825 and it gives me a handy-dandy bar—or, graph sourced from Wikipedia 57 00:04:14,825 --> 00:04:20,269 which tells me that the 2013 population of Zimbabwe was 14.15 million. 58 00:04:21,269 --> 00:04:24,377 Okay, great. Excellent. I think you have really got the hang of it. 59 00:04:24,826 --> 00:04:27,747 Thank you. And, Command-Q to close the browser when I am done. 60 00:04:28,439 --> 00:04:28,838 Good. 61 00:04:29,285 --> 00:04:29,814 Which does what I expect. 62 00:04:30,345 --> 00:04:35,040 There may be some points during this where there is some down time. Where I am going to ask you do download some software. 63 00:04:35,634 --> 00:04:36,148 Sure. 64 00:04:36,622 --> 00:04:41,225 So while it's going on, I encourage you to, you know, look and see what you can see on the screen and just describe what you see. 65 00:04:41,225 --> 00:04:43,869 In order to fill up some of that time and make good use of it. 66 00:04:44,343 --> 00:04:44,874 Okay. 67 00:04:45,834 --> 00:04:48,367 So, now we are going to begin the real experiment. 68 00:04:50,230 --> 00:04:54,704 I am going to have you... You're going to be testing a piece of software called Tor Browser 69 00:04:54,704 --> 00:05:01,427 which is a special web browser that has... that is used for anonymity purposes. 70 00:05:01,427 --> 00:05:02,738 And this is the list of tasks that you are going to do. 71 00:05:03,213 --> 00:05:04,182 Okay. 72 00:05:04,966 --> 00:05:08,663 And do these in the way that you would normally do them, if you were going to follow these steps at home. 73 00:05:09,343 --> 00:05:10,168 Okay. So... 74 00:05:10,658 --> 00:05:11,588 Do you have any other questions before we begin? 75 00:05:12,014 --> 00:05:12,601 No, I'm good. 76 00:05:13,553 --> 00:05:20,747 So, first instruction is to download Tor. So I am going to fire up Chrome again. 77 00:05:21,940 --> 00:05:26,869 And I actually know that Chrome will just allow me to type searches in the search bar, 78 00:05:26,869 --> 00:05:31,625 so I am going to type in "tor mac download". 79 00:05:31,625 --> 00:05:34,620 And that gives me some suggestions. I pick the first one. 80 00:05:34,620 --> 00:05:44,471 Which takes me to "Download Tor" from www.torproject.com, or .org. That looks like a reasonably reputable site. 81 00:05:44,471 --> 00:05:46,598 It's an HTTPS site. 82 00:05:47,089 --> 00:05:55,906 I have a warning about wanting to do things differently so I am just going to pop that open in a new tab... 83 00:05:55,906 --> 00:06:00,764 No. I clicked on that wrong... Pop that open in a new tab. 84 00:06:00,764 --> 00:06:04,831 And in the mean time, I am going to hit the "Download Tor Browser" button. 85 00:06:04,831 --> 00:06:07,603 So that is a 40-meg download. 86 00:06:08,269 --> 00:06:14,343 I'm going to go read the warnings about things that I should and shouldn't do on Tor. 87 00:06:14,788 --> 00:06:22,418 Because I am assuming that I want to have maximum security so, follow all of the warnings, make sure I don't do this wrong. 88 00:06:26,178 --> 00:06:28,793 Okay. Seven and a half megs of download to go. 89 00:06:29,492 --> 00:06:32,744 All right, in the meantime, I am going to... 90 00:06:33,293 --> 00:06:38,314 pop open a new tab and read about "tor onions". 91 00:06:41,870 --> 00:06:47,173 And again, that tells, takes me to the Tor Project webpage. 92 00:06:47,173 --> 00:06:51,314 Ooh, I have a "hidden wiki" for Tor onion URLs. 93 00:06:51,314 --> 00:06:55,456 That looks like I might want to open that up and read more about that. 94 00:06:56,723 --> 00:07:02,516 And pop open another tab and type "tor onions" again because there were a lot more links 95 00:07:02,516 --> 00:07:07,156 so I am going to read the Wikipedia page on Tor as well. 96 00:07:07,156 --> 00:07:12,694 It tells me it's a network for preserving anonymity and resisting censorship. 97 00:07:14,134 --> 00:07:23,540 Okay, here's the table of contents... Okay. This appears to be a slightly more historical and theoretical document. 98 00:07:23,540 --> 00:07:29,687 So I am going to go back to the Tor Project. In another tab. 99 00:07:29,687 --> 00:07:31,934 And click the "Documentation" link. 100 00:07:31,934 --> 00:07:36,163 And have a look at the "Installing Tor on Mac OS X". 101 00:07:37,286 --> 00:07:42,766 Okay. It tells me it wants me... this is the compile-it-yourself version. 102 00:07:42,766 --> 00:07:48,447 And the recommended way is to use the Tor Browser Bundle. Which I think I am downloading. 103 00:07:48,447 --> 00:07:52,199 Yep. I am downloading still. 104 00:07:52,199 --> 00:08:02,110 But I am just curious what other stuff... Okay. Well there's definitely a suggestion on configuring your application to use Tor. 105 00:08:02,110 --> 00:08:04,721 So I should probably keep that tab open. 106 00:08:04,721 --> 00:08:12,562 Okay! my download appears to have completed so I am going to let Chrome open the disk image. 107 00:08:12,562 --> 00:08:14,641 It is verifying right now. 108 00:08:15,291 --> 00:08:17,418 Mounting the disk. 109 00:08:17,418 --> 00:08:20,983 Drag Tor Browser Bundle into Applications. 110 00:08:21,800 --> 00:08:26,290 Okay. Copying... 95 megs. 111 00:08:30,252 --> 00:08:32,934 All right. 112 00:08:33,715 --> 00:08:37,937 And Shift key, pop open my applications, 113 00:08:39,163 --> 00:08:41,615 and there is Tor Browser. 114 00:08:43,965 --> 00:08:49,094 "'TorBrowser' can't be opened because it's from an unidentified developer." 115 00:08:49,094 --> 00:08:52,097 Grr! I express some frustration at this fact. 116 00:08:52,740 --> 00:08:53,606 [Laughter.] 117 00:08:54,727 --> 00:08:59,413 [Sighs.] And, Shift-U, 118 00:08:59,413 --> 00:09:05,024 I tend to actually, when I am changing quarantine bits, 119 00:09:05,024 --> 00:09:12,517 rather than turning off quarantine checking on the entire system, I just remove the quarantine bit. 120 00:09:12,517 --> 00:09:17,288 So, I go to "cd slash Applications", 121 00:09:17,717 --> 00:09:21,494 "ls minus l", 122 00:09:22,312 --> 00:09:24,517 "Tor Browser". Excellent. 123 00:09:24,517 --> 00:09:33,640 There is my Tor Browser. So I, uh, is it... "chattr"? 124 00:09:35,871 --> 00:09:47,825 "chflags", "d", "com dot apple dot quarantine Tor Browser". 125 00:09:48,269 --> 00:09:53,711 Argh. It's "chattr". 126 00:09:57,044 --> 00:10:00,345 Okay, it doesn't want to let me do that which means I need to go to the System Preferences, unfortunately. 127 00:10:00,977 --> 00:10:06,398 Mmhmm. And we will just undo anything that you do, so don't worry about it. 128 00:10:07,222 --> 00:10:16,063 Okay. It wanted me to do something again... I forgot what. Warning says, 129 00:10:19,392 --> 00:10:23,768 "Security preferences", okay. 130 00:10:25,957 --> 00:10:37,245 Okay... "Security & Privacy"... "General"? 131 00:10:37,602 --> 00:10:41,202 Ah, here we go. "Open Anyway"! Click the lock to make the changes. 132 00:10:42,442 --> 00:10:44,841 Uh, it's "password" on this computer. 133 00:10:50,145 --> 00:10:54,527 Okay, let's see if I can do that from an identified developer. 134 00:10:56,980 --> 00:11:01,611 Actually, I am going to say open that anyway. Let's see what happens. 135 00:11:01,611 --> 00:11:07,373 Maybe I don't have to open up my system too much. 136 00:11:07,373 --> 00:11:11,828 I see the bouncy Chrome browser, or browser ball. 137 00:11:11,828 --> 00:11:16,648 It's verifying. Waiting, waiting. 138 00:11:22,196 --> 00:11:24,773 Okay, so yes. I want to open Tor Browser. 139 00:11:27,706 --> 00:11:34,328 Okay, I now have a dialogue that asks me to configure my Tor settings. 140 00:11:34,328 --> 00:11:42,479 If I am connecting directly to the Tor network or if my computer is censored or proxied somehow. 141 00:11:42,479 --> 00:11:50,585 Looking at this, I would almost actually choose the censor or proxy mode, just because I work in computers 142 00:11:50,585 --> 00:11:54,274 and I know that my work network actually filters Tor... 143 00:11:54,274 --> 00:12:01,625 And I may have heard stories on the news about various consumer ISPs also filtering traffic. 144 00:12:01,625 --> 00:12:11,604 But! I am tempted to go with censored, but I am going to try the easy, "this will work in most suggestions—most situations" choice 145 00:12:11,604 --> 00:12:14,207 and just connect directly. 146 00:12:14,692 --> 00:12:19,736 Okay, connecting. It is telling me it is doing stuff. Loading network status... 147 00:12:20,866 --> 00:12:22,610 Pausing a little bit? 148 00:12:22,610 --> 00:12:26,416 Okay, I can close the System Preferences now. 149 00:12:28,366 --> 00:12:34,702 And, while it is doing its thing, I am just going to go back to reading the instructions about Tor. 150 00:12:35,219 --> 00:12:38,669 Okay, cool. Tor seems to have loaded. 151 00:12:38,669 --> 00:12:41,937 "Congratulations, this browser is configured to use Tor" 152 00:12:41,937 --> 00:12:46,517 and the first link it gives me is a "Test for Network Settings" so I am going to click that. 153 00:12:46,517 --> 00:12:48,596 Which gets me as far as step 3. 154 00:12:49,316 --> 00:12:49,871 Right. 155 00:12:52,384 --> 00:12:58,096 This is definitely not nearly as fast as regular Internet. 156 00:13:00,192 --> 00:13:02,307 I see you have NoScript loaded. 157 00:13:02,307 --> 00:13:06,144 Okay, great, the browser is configured to use Tor correctly. 158 00:13:06,684 --> 00:13:17,307 So now that I have Tor running, I am going to use the default searches inside the Tor Browser, so that appears to be Startpage, and 159 00:13:17,307 --> 00:13:20,039 I am going to type in "onions". 160 00:13:23,929 --> 00:13:34,546 I am going to pop open a new tab, and in that new tab, I am going to see if anybody talks about YouTube over Tor, 161 00:13:34,546 --> 00:13:40,339 just because I think that maybe not all sites on the Internet are going to work correctly when Tor is in use. 162 00:13:40,339 --> 00:13:49,567 Okay, so... back to Startpage, it gives me lots of stuff about onion foods. 163 00:13:50,544 --> 00:13:52,595 Not so much about Tor onions. 164 00:13:53,068 --> 00:13:56,191 Okay, good. We actually just needed, wanted the search here. 165 00:13:56,191 --> 00:13:58,953 But. You may go ahead and do an additional search if you want. 166 00:13:59,850 --> 00:14:06,397 I just put in "onions" and "tor" into the search bar to see if that tells me more stuff. 167 00:14:06,397 --> 00:14:12,061 And okay, there are a whole lot more results here now. 168 00:14:12,061 --> 00:14:15,294 There's a Reddit link, there is a second search called "Hidden Wiki" 169 00:14:15,294 --> 00:14:23,495 which gives me a URL that is line noise dot onion, and that looks like something interesting to click on. 170 00:14:24,058 --> 00:14:27,313 And I click on it in the background. 171 00:14:27,623 --> 00:14:35,587 Ooh, here is a link on the "youtube over tor" search that I did called "Watching YouTube over the TOR network" from Ubuntu Forums. 172 00:14:35,587 --> 00:14:46,875 That looks like that might be helpful if I am trying to find videos on YouTube. 173 00:14:47,534 --> 00:14:52,315 Some people complain that it doesn't always work. 174 00:14:53,269 --> 00:14:55,907 Uh... 175 00:14:58,022 --> 00:15:04,807 Okay, not seeing a huge amount of warnings right away that tells me that it shouldn't work. 176 00:15:04,807 --> 00:15:13,020 I am going to open a new private window though inside the Tor Browser, because, just on the assumption that I might be searching for controversial videos, 177 00:15:13,020 --> 00:15:29,923 so I am going to, you know, dispose of all of my cookies and tracking information and then go to "https youtube", "youtube dot com" in my new private window. 178 00:15:34,206 --> 00:15:39,053 And it tells me I am viewing YouTube in English, that is cool. So it's not routing me through Kazakhstan. 179 00:15:39,465 --> 00:15:45,679 Let me see if I can type in "ode to joy" in the search bar, in YouTube. 180 00:15:47,821 --> 00:15:52,804 Okay. There's a whole bunch of... now I... 181 00:15:52,804 --> 00:15:54,287 Stupid Google. I don't want to look at your ads. 182 00:15:54,745 --> 00:15:55,587 [Laughter.] 183 00:15:57,042 --> 00:16:00,599 Okay, so I clicked on the first one. 184 00:16:00,599 --> 00:16:06,933 Hmm. "Cookies help us deliver our services. By using our services, you agree to the use of our cookies." says YouTube. 185 00:16:06,933 --> 00:16:12,590 Well, fine. I guess I can accept that because I am running in a private browsing window 186 00:16:12,590 --> 00:16:17,614 and my cookies will be destroyed after this session anyway. So... 187 00:16:21,380 --> 00:16:23,676 That was not the video I clicked on. This is somebody's channel. 188 00:16:24,248 --> 00:16:26,014 "A plugin is need to display"... 189 00:16:26,014 --> 00:16:30,620 Oh, okay, it loaded, I guess it fell back to HTML5. 190 00:16:31,072 --> 00:16:37,889 And you have you have the little plugin warning up in my... about bar. But... 191 00:16:53,969 --> 00:16:58,467 Okay, this takes a while. I am just going to go to my settings, okay. 192 00:16:58,467 --> 00:17:03,168 I can't reduce quality on the video any so I guess I am just kind of stuck waiting. 193 00:17:06,806 --> 00:17:19,363 It is curious that this session is giving me YouTube in German. So... I guess this particular connection has routed me through Germany. 194 00:17:21,058 --> 00:17:26,532 Which could get kind of annoying, so I am going to pop open a new tab in the same private browsing window 195 00:17:26,532 --> 00:17:34,446 and go to "www dot google dot com slash n c r" which is "no country redirect". 196 00:17:34,446 --> 00:17:42,108 And that will set a cookie in that session to use English US. 197 00:17:42,601 --> 00:17:53,270 So. Now I am waiting for my flash mob YouTube video to load. I am just pausing the video playback to let it buffer. 198 00:17:54,368 --> 00:17:55,978 Doesn't seem to be winning, so... 199 00:18:00,646 --> 00:18:04,813 You don't need to watch the whole thing, but just enough to get an experience of it. 200 00:18:14,648 --> 00:18:16,401 This is just like T-Mobile! 201 00:18:16,890 --> 00:18:18,155 [Laughter.] 202 00:18:22,115 --> 00:18:29,126 Okay, so that is... Yep, I wish to close both of those tabs. Okay. 203 00:18:29,681 --> 00:18:30,961 Good. 204 00:18:31,521 --> 00:18:38,230 Now back to my onion menu. Okay, where is the onion menu on Tor Browser? 205 00:18:39,296 --> 00:18:45,909 There's the Tor Browser... Here's a little coffee cup... What if I click on the coffee cup? 206 00:18:45,909 --> 00:18:48,556 Clicking on the coffee cup doesn't do anything. 207 00:18:52,433 --> 00:18:58,951 Um, "Options"? No. That is the... that's just the launcher options. 208 00:18:59,953 --> 00:19:07,507 Okay. "Tor Browser Preferences". That is not what I was looking for. 209 00:19:12,824 --> 00:19:19,250 Well, let's find Tor. 210 00:19:19,653 --> 00:19:26,797 "TorBrowser - ux", "TorBrowser"... Okay, that's my Tor Browser. 211 00:19:28,693 --> 00:19:37,892 Hmm, okay. "Tools". Those are Firefox tools, it looks like. 212 00:19:38,336 --> 00:19:41,359 Which... HTTPS Everywhere settings... 213 00:19:42,034 --> 00:19:48,611 "Use 'New Identity' under the onion menu." Hm. Okay. 214 00:19:53,121 --> 00:20:00,718 Let me type in "onion" in the search bar and... nope. 215 00:20:00,718 --> 00:20:03,544 That gives me Wikipedia links for onions and dictionary definitions for the onions 216 00:20:03,544 --> 00:20:07,070 and Bing searches and foods, but... 217 00:20:08,105 --> 00:20:15,291 That... okay. Let me go back to the Tor docs. 218 00:20:15,291 --> 00:20:25,327 But actually, if I am being all paranoid and stuff, I am going to close out my Chrome tab and go back again... 219 00:20:25,327 --> 00:20:36,028 And I am going to type in this new search tab, "osx tor onion settings". 220 00:20:37,308 --> 00:20:39,890 Let me see if that... 221 00:20:39,890 --> 00:20:49,146 That takes me back to the Tor Project Mac OS X install instructions. So that looks like something I want to read some more. 222 00:20:49,718 --> 00:20:53,791 Okay. "Verify download". 223 00:20:59,808 --> 00:21:06,132 Okay, so I'm going to look at the Tor FAQ entry for "Tor doesn't work". 224 00:21:08,769 --> 00:21:17,234 Tor seems to be working, but it's not entirely clear to me where all my Tor settings are. 225 00:21:19,241 --> 00:21:29,278 Let me go into System Preferences, maybe there is a... maybe there is a preference in there. 226 00:21:29,594 --> 00:21:34,509 "tor". Nope. No system preferences for "tor". 227 00:21:34,509 --> 00:21:39,512 "onion". No, no system preferences for "onion" either. 228 00:21:40,172 --> 00:21:45,032 Searching for "tor". 229 00:21:45,032 --> 00:21:53,623 And now I've got TorBrowser and TorBrowser but no other settings. 230 00:21:56,916 --> 00:21:59,162 Hm. "Tor Browser Bundle". 231 00:22:05,269 --> 00:22:10,709 Let me look at the Torify HOWTO. Maybe that will tell me. 232 00:22:14,662 --> 00:22:17,298 Okay. 233 00:22:19,703 --> 00:22:24,113 Tells me all about setting up proxy and SOCKS. 234 00:22:28,839 --> 00:22:33,990 "Do not mix modes of anonymity"... "Tor over Tor"... "Software updaters"... 235 00:22:37,105 --> 00:22:41,001 I think not. Uh... 236 00:22:46,353 --> 00:22:52,385 Ooh! Tor manuals. Let's see if there is one of those for OS X. 237 00:22:52,957 --> 00:22:58,230 "Configuring manually", "Configuring a relay". That looks like that might be useful. 238 00:22:59,868 --> 00:23:04,949 No, that's for Debian. Doesn't say for Mac. Okay. 239 00:23:05,567 --> 00:23:12,344 Let's back up a little bit and "osx tor settings" in Startpage search. 240 00:23:14,096 --> 00:23:21,178 That's the... Tor Browser Bundle... 241 00:23:30,172 --> 00:23:35,096 Okay... "Why use Tor" on a Mac, "What Tor can and cannot do". 242 00:23:35,096 --> 00:23:39,193 Okay, step 1, "Install the Tor Browser Bundle". 243 00:23:39,193 --> 00:23:47,780 Step 2, "Configure Tor to use the..." Tor... 244 00:23:48,170 --> 00:23:51,596 Okay, so it is telling me to do something with Vidalia. 245 00:23:52,830 --> 00:23:55,386 "vidalia". 246 00:23:56,308 --> 00:24:01,189 Nope, that gives me links to Georgia and songs on iTunes. 247 00:24:02,446 --> 00:24:04,517 Tor Browser... 248 00:24:08,952 --> 00:24:11,828 Okay, hm... 249 00:24:12,432 --> 00:24:20,182 Well, this page on the Internet tells me that in version 3.5 of the Tor Browser Bundle, "About"... 250 00:24:20,182 --> 00:24:28,994 and I have something definitely newer than 3.5. They bundled Vidalia right into it, and... 251 00:24:34,634 --> 00:24:38,631 Clicking around to see... How to I open new...? 252 00:24:39,218 --> 00:24:48,144 Okay, so this tells me that I am going to have to start looking in "torrc settings"? 253 00:24:55,775 --> 00:25:04,760 Let's see what happens if I type "tor browser bundle new circuit". 254 00:25:15,727 --> 00:25:29,119 Okay, so I clicked on the link to Stack Exchange, that says how do I switch a, to a new circuit? 255 00:25:29,833 --> 00:25:33,683 "Tools". "View"... 256 00:25:39,566 --> 00:25:45,273 Hm. "'New Identity' under the—under the onion menu." 257 00:25:48,948 --> 00:25:50,954 Hm. I feel like I am... 258 00:25:50,954 --> 00:25:54,817 Oh, hey! There's the onion menu. That was not obviously defined at all! 259 00:25:55,483 --> 00:26:01,211 Okay. Cool. Now that I found the New Identity in the onion menu, I will click that. 260 00:26:01,211 --> 00:26:10,711 It closed all of my windows and it gave me a "your browser is connected to Tor", and... 261 00:26:10,711 --> 00:26:23,625 Okay, I went to 165.254 something, as my IP address. I am going to go "New Identity" again, close my window, and I am going to test my settings. 262 00:26:24,388 --> 00:26:38,895 And it gave me 104.131, so I believe that maybe the New Identity is... actually tearing down my circuit and giving me a different exit node. Awesome. 263 00:26:38,895 --> 00:26:42,704 "Cookie Preferences". Hmm. 264 00:26:43,259 --> 00:26:51,882 Alright well, I am going to go to "www dot", oh, who's full of cookies... 265 00:26:52,477 --> 00:26:57,683 "gawker dot com". They're totally going to give me cookies and stuff. 266 00:26:58,116 --> 00:26:59,270 [Laughter.] 267 00:27:03,365 --> 00:27:07,211 And maybe, yeah... yahoo.com while I am at it. 268 00:27:07,211 --> 00:27:09,634 Now I should have a whole bunch of cookies. 269 00:27:10,670 --> 00:27:15,946 So if I go to Cookie Protections, 270 00:27:16,461 --> 00:27:21,726 I don't see any cookies in there. I guess that's cool. 271 00:27:22,983 --> 00:27:30,416 Let me go to Tor Browser Preferences. And go to "Privacy". 272 00:27:34,651 --> 00:27:40,926 I am going to click "Content" and then to go to 273 00:27:41,721 --> 00:27:44,867 I am looking for all of the cookies and stuff in here. 274 00:27:46,388 --> 00:27:47,596 Da da daaa... 275 00:27:52,501 --> 00:27:58,214 "General"... "Tabs", "Content"... Let's see what's up... 276 00:27:58,214 --> 00:28:03,041 That's pop-up exceptions, that's fonts and colors... 277 00:28:04,003 --> 00:28:07,708 "Privacy". "Learn More". 278 00:28:08,750 --> 00:28:11,826 Okay... it's not quite what I wanted to have happen. 279 00:28:15,053 --> 00:28:17,612 Anyway, "Cookie Preferences". 280 00:28:18,780 --> 00:28:25,060 Let's see. I am going to click the "Protect New Cookies" button and see what happens. 281 00:28:25,992 --> 00:28:34,132 "www.google.com/ncr". Because that should set a cookie. 282 00:28:38,583 --> 00:28:42,804 Okay, and then what happens if I go to Cookie Protections? Hm. Still no cookies. 283 00:28:42,804 --> 00:28:45,579 Not sure what that does for me then. 284 00:28:47,555 --> 00:28:49,153 "Preferences". 285 00:28:50,325 --> 00:28:56,799 Okay, this is the usual Firefox preferences that I would expect. 286 00:28:56,799 --> 00:29:00,065 I am not going to mess with those any. 287 00:29:00,065 --> 00:29:03,561 Okay. I see that it's got private browsing turned on. 288 00:29:03,561 --> 00:29:05,990 Turns off all of the plugins, which is good. 289 00:29:05,990 --> 00:29:13,525 Restricts all the third-party cookies, and I guess spoofs... spoofs browser settings. 290 00:29:13,525 --> 00:29:19,236 Which is actually... I am going to type in "what is my useragent". 291 00:29:19,236 --> 00:29:23,060 Just to see what my browser identifies itself as. 292 00:29:25,204 --> 00:29:30,772 And! There we go. whatismyuseragent.com. 293 00:29:31,344 --> 00:29:45,548 And it tells me that I am probably using "Mozilla 5.0 Windows NT 6.1 Gecko Firefox". 294 00:29:45,548 --> 00:29:48,758 Sure, why not. This doesn't look anything like this Mac full of nuclear secrets! Awesome. 295 00:29:49,423 --> 00:29:49,922 [Laughter.] 296 00:29:50,525 --> 00:29:53,556 Sounds awesome. 297 00:29:53,556 --> 00:29:56,135 Okay. And open network settings. 298 00:29:56,135 --> 00:30:02,902 Ah! And this probably lets me to change the thing I selected at the beginning 299 00:30:02,902 --> 00:30:07,630 about needing to go through a firewall or proxy or some sort of censorship thing. So. 300 00:30:07,630 --> 00:30:11,271 I am just going to turn those on and... 301 00:30:13,463 --> 00:30:20,247 Okay. I am going to turn off the proxy because I don't know that, I don't know what my proxy settings are, let's say. 302 00:30:20,247 --> 00:30:27,576 So I am just going to say that I am on a network that only allow 80 and 443. And my ISP tries to block Tor. 303 00:30:27,576 --> 00:30:37,626 I am going to go like that and then I am going to go New Identity which seems like a reasonable guess to make Tor do the things. 304 00:30:38,589 --> 00:30:42,069 And... do the Tor network check. 305 00:30:42,674 --> 00:30:50,548 I got a new IP address, so that's cool. Seems to have worked without any hassle to me. 306 00:30:51,782 --> 00:30:58,557 "Network Settings". Yep, network settings are still back the way that I left them. I am using only 80 and 443. 307 00:31:01,034 --> 00:31:09,839 Good, and so finally, just go along the toolbar and give a summary of what you think each UI element does, in the top part of the browser here. 308 00:31:10,345 --> 00:31:21,144 Okay, so this is the good old NoScript, and it is set to block all JavaScript right now. Which is cool. 309 00:31:22,202 --> 00:31:29,430 It appears to be just like the NoScript I run in my browser, so no surprises there. 310 00:31:29,430 --> 00:31:37,276 Now that I finally recognize the little green onion, I see that's the Tor menu and that tells me, 311 00:31:37,276 --> 00:31:40,079 or that gives me control over the Tor module itself. 312 00:31:40,079 --> 00:31:45,479 I can tear down circuits, I can tell what I want it to do with cookies, 313 00:31:45,479 --> 00:31:47,836 configure all the other details. 314 00:31:47,836 --> 00:31:55,605 I didn't click on the "About", but I guess that tells me what version I am running if I have to file a bug report. 315 00:31:55,605 --> 00:32:01,576 It also lets me change the network settings. 316 00:32:01,576 --> 00:32:06,682 I've got the usual sort of tabbed browsing experience and I can click the little plus to open up all kinds of new tabs. 317 00:32:06,682 --> 00:32:17,556 I've got the usual sort of omnibox where I can either type in any URL that I want to browse to or I can type in a search string. 318 00:32:18,209 --> 00:32:27,803 And if I type in "search string", it sends me to startpage.com which seems to be the browser's default search provider, 319 00:32:27,803 --> 00:32:33,221 as is shown in the little search tool, 320 00:32:33,698 --> 00:32:37,602 and I have a selection of other search engines I could use... 321 00:32:38,301 --> 00:32:44,220 Startpage is the default for some reason, there is also DuckDuckGo, Google, Amazon, Bing, 322 00:32:44,220 --> 00:32:46,171 I guess they get progressively worse as you go down the list. 323 00:32:46,621 --> 00:32:47,540 [Laughter.] 324 00:32:48,247 --> 00:32:53,155 And then the typical Firefox settings menu. 325 00:32:55,003 --> 00:33:05,335 I didn't play with HTTPS Everywhere. But it seems to be set up to force HTTPS wherever possible. 326 00:33:09,229 --> 00:33:09,903 Great, that is the end! 327 00:33:10,384 --> 00:33:10,784 Okay.
