00:00:00,199 --> 00:00:06,640
this is not a test this is an actual Techquickie episode and for your own

2
00:00:04,839 --> 00:00:11,360
safety I recommend you do not leave your computer for the next 5 minutes of

3
00:00:09,080 --> 00:00:15,719
course real emergency alerts are designed to warn you of things that are

4
00:00:12,960 --> 00:00:20,640
somehow even more important than new YouTube videos but they've always been

5
00:00:18,359 --> 00:00:26,400
kind of mystifying with their weird combination of robotic voices and

6
00:00:23,279 --> 00:00:28,920
disconcerting sounds wouldn't it just be

7
00:00:26,400 --> 00:00:34,280
easier for a human announcer to get on the air and warn us of an impending

8
00:00:30,920 --> 00:00:37,559
pandemic hurricane or Godzilla attack

9
00:00:34,280 --> 00:00:40,239
well no the emergency alert system or

10
00:00:37,559 --> 00:00:45,960
EAS used in the United States is designed to get messages out as quickly

11
00:00:43,239 --> 00:00:50,280
as possible and this is difficult to do without automation I mean in certain

12
00:00:48,239 --> 00:00:55,079
kinds of emergencies like an approaching tornado you might only have a couple of

13
00:00:52,840 --> 00:01:00,199
minutes to prepare so there isn't necessarily time for a human being to

14
00:00:57,719 --> 00:01:06,680
scoot off to the recording studio do a few takes apply some autotune then sort

15
00:01:03,440 --> 00:01:08,439
out where the message should go by then

16
00:01:06,680 --> 00:01:12,720
you'll probably be a couple miles off the ground chatting it up with the

17
00:01:09,759 --> 00:01:18,360
Wicked Witch of the West and speaking of where the message should go those three

18
00:01:15,520 --> 00:01:22,640
extremely harsh sounding tones you hear at the beginning of a warning work kind

19
00:01:20,640 --> 00:01:28,240
of like those annoying sounds that you'd hear from a dialup modem they sound like

20
00:01:25,920 --> 00:01:33,640
random screeches but they actually contain critical information about where

21
00:01:30,720 --> 00:01:38,960
the warning needs to go they are called same headers and when they reach a TV or

22
00:01:36,720 --> 00:01:44,840
radio station from whichever government Authority issued the warning special EAS

23
00:01:42,119 --> 00:01:50,079
equipment at the station can decode them and automatically forward information to

24
00:01:47,159 --> 00:01:55,880
listeners about what the emergency is which area it's affecting and what time

25
00:01:52,799 --> 00:01:58,719
the warning expires and since same code

26
00:01:55,880 --> 00:02:02,119
specifies specific geographic regions you won't have to worry about getting

27
00:02:00,280 --> 00:02:07,560
that super important show you're watching interrupted by an e warning for

28
00:02:04,280 --> 00:02:09,520
Los Angeles if you're living in New York

29
00:02:07,560 --> 00:02:14,920
the next thing you'll hear is an attention

30
00:02:11,680 --> 00:02:18,200
tone which as you can probably guess is

31
00:02:14,920 --> 00:02:19,519
there to annoy you to get your attention

32
00:02:18,200 --> 00:02:23,400
so hopefully you'll look up from your 3DS for long enough to learn there's a

33
00:02:21,480 --> 00:02:28,480
serial killer on the loose so although many have complained about how harsh the

34
00:02:26,160 --> 00:02:33,640
tone sounds I doubt they're going to be changing that anytime

35
00:02:30,360 --> 00:02:35,879
soon finally comes the voice that sounds

36
00:02:33,640 --> 00:02:41,239
like something out of your nightmares matter of factly delivering all the Gory

37
00:02:38,120 --> 00:02:43,480
details of your impending doom or maybe

38
00:02:41,239 --> 00:02:48,760
it's just a minor flood 20 mil away it can be kind of hard to understand for

39
00:02:45,519 --> 00:02:51,080
some people again the automated EAS

40
00:02:48,760 --> 00:02:56,720
voices were designed to make message dissemination quicker even if that comes

41
00:02:54,000 --> 00:03:01,680
at a creepy cost with that in mind the US's National Weather Service has tried

42
00:02:59,319 --> 00:03:06,000
to improve proed the voice over the years going from something that sounded

43
00:03:03,680 --> 00:03:10,879
suspiciously like old school Microsoft Sam a slow moving storm system will move

44
00:03:09,000 --> 00:03:16,280
across the Northern Great Lakes Region today and tonight to a voice that

45
00:03:13,120 --> 00:03:18,599
actually isn't that terrible anymore

46
00:03:16,280 --> 00:03:23,560
Zone forecast for Central and Southeast Montgomery County for the rest of the

47
00:03:20,720 --> 00:03:30,599
overnight mostly clear well that's cool in all lus but TV

48
00:03:26,760 --> 00:03:33,439
radio please I stream everything why is

49
00:03:30,599 --> 00:03:38,959
the EAS relying on such ancient technology well there are advantages to

50
00:03:36,159 --> 00:03:44,680
using radio to warn people it's a simpler technology than the internet and

51
00:03:41,280 --> 00:03:47,040
is likely to be more reliable if a major

52
00:03:44,680 --> 00:03:50,480
emergency knocks out power and internet service with it you're going to be

53
00:03:48,760 --> 00:03:55,640
pretty happy you've still got that battery powered radio in fact you can

54
00:03:53,200 --> 00:04:00,000
buy same compatible radios that pick up special frequencies that will

55
00:03:57,200 --> 00:04:04,239
automatically broadcast EAS alerts but stay quietly in the corner otherwise but

56
00:04:02,959 --> 00:04:08,720
if you don't want to do that many cellular carriers are now broadcasting

57
00:04:06,319 --> 00:04:14,000
EAS messages directly to smartphones anyway so you won't be left in the dark

58
00:04:10,879 --> 00:04:16,320
if you're just not a TV or radio person

59
00:04:14,000 --> 00:04:21,240
and good thing too because nothing ruins selfie time with your squad quite like

60
00:04:18,359 --> 00:04:26,680
hailstones the size of grapefruits tunnel bear VPN lets you

61
00:04:24,479 --> 00:04:31,039
tunnel to 20 different countries allowing you to browse the internet and

62
00:04:28,280 --> 00:04:36,120
use online services as though you are in a different country it's easy to use

63
00:04:33,919 --> 00:04:41,600
your connection gets encrypted and they have an industry-leading privacy policy

64
00:04:38,600 --> 00:04:44,720
they've got apps for iOS Android PC Mac

65
00:04:41,600 --> 00:04:47,240
and also a Chrome extension and it is as

66
00:04:44,720 --> 00:04:51,759
simple as downloading the app getting 500 megabytes of free data with no

67
00:04:49,880 --> 00:04:57,840
credit card required which is pretty freaking cool clicking the little button

68
00:04:54,039 --> 00:05:00,199
and boom all of the poking around and

69
00:04:57,840 --> 00:05:05,400
nonsense that goes along with the PN use for personal use is eliminated by tunnel

70
00:05:03,360 --> 00:05:11,000
