I&#8217;ll definitely continue to use both platforms; I just need to decide which one will be my primary device.<\/p>\n<p>In addition to a great notification system and the ability to run background apps, I&#8217;ve found another point in Android&#8217;s favor, and had a fun time geeking out with it last night. <a href=\"http:\/\/www.google.com\/sky\/skymap.html\">Google Sky Map<\/a>, which was born in Google&#8217;s Pittsburgh office, allows you to do what you&#8217;d expect from Google: search the sky.\u00a0I noticed that none of the daytime\/indoor demos really showed the app &#8220;in the wild,&#8221; so I waited for the <a href=\"http:\/\/aa.usno.navy.mil\/data\/docs\/RS_OneDay.php\">moonrise<\/a> last night and then shot a quick video. I decided to search for the Moon for three reasons: First, I know what the Moon looks like and can confirm the app&#8217;s accuracy. Second, it&#8217;s the only natural object in the night sky that my video camera is able to capture. And finally, I was hoping that it would lead me to <a href=\"http:\/\/wysz.com\/wyszdom\/2009\/01\/david\/\">David Moon<\/a>. He totally freaks out when I find him at night. It&#8217;s hilarious.<\/p>\n<p>Here&#8217;s my quick demo:<\/p>\n<p><iframe loading=\"lazy\" title=\"Google Sky Map\" width=\"660\" height=\"371\" src=\"https:\/\/www.youtube.com\/embed\/rv6X8H3Hw6Q?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<p>My camera did pretty well on full-auto; I think you get the gist of what&#8217;s going on. The bright circle is the Moon. You&#8217;ll note that the Moon actually appears a bit to the left of where Sky Map said it would be. It&#8217;s possible that my compass needs to be calibrated. The difference could also be caused by the fact that\u00a0<a href=\"http:\/\/www.ngdc.noaa.gov\/geomagmodels\/struts\/calcDeclination\">at my location<\/a>, magnetic north is about 14\u00b0 east of true north, and the app currently does not account for\u00a0<a href=\"http:\/\/en.wikipedia.org\/wiki\/Magnetic_declination\">magnetic declination<\/a>.<\/p>\n<p>Did you like the music? It&#8217;s my first time publishing a video with YouTube&#8217;s\u00a0<a href=\"http:\/\/www.youtube.com\/audioswap_main\">AudioSwap<\/a> feature. I chose a short song called &#8220;Happy and Happy&#8221; because it sounded corny enough to be in one of those science videos you watch in school.\u00a0I&#8217;d also like to note that this is the first time I made use of one of YouTube&#8217;s <a href=\"http:\/\/www.youtube.com\/blog?entry=Lsn9BnVuSAM\">new tags<\/a> to make sure the video was presented properly. I uploaded a raw HDV file, which is 1440&#215;1080 pixels. But that doesn&#8217;t sound like it matches the 16:9 aspect ratio, does it? That&#8217;s because DV and HDV use a horrible concept called &#8220;non-square pixels&#8221; which I&#8217;m sure was a good idea at some point for technical reasons, but in today&#8217;s world is just an annoyance. So, to make sure YouTube knew to present it as widescreen, I added this tag:\u00a0yt:stretch=16:9. Worked like a charm, and it meant I didn&#8217;t have to do any transcoding on my end.<\/p>\n<p>So, the next time you see one of those articles about &#8220;Object X will be visible to the naked eye tonight,&#8221; grab your (or your friend&#8217;s) Android device and find that object in no time. Or if you want to find something tonight, try searching Google (without the brackets) for [tonight&#8217;s sky] or something similar. Before heading outside, however, check to see if the object you&#8217;re looking for appears above the yellow horizon line. If it&#8217;s below the horizon, you won&#8217;t be able to see it without some heavy-duty Earth-moving equipment, so make sure you look up the best viewing time for your area.<\/p>\n<p>Don&#8217;t have access to an Android device? Don&#8217;t forget you can still explore the sky <a href=\"http:\/\/www.google.com\/sky\/\">with your browser<\/a> or <a href=\"http:\/\/earth.google.com\/sky\/\">with Google Earth<\/a> before heading out to find things yourself.<\/p>\n<p>I haven&#8217;t done a lot of stargazing in my life, and it&#8217;s a bit difficult to do where I live now, but I have a few favorite sky-watching moments:<\/p>\n<ol>\n<li>As a birthday present for me one year in elementary school, my parents won a fundraising auction for an evening with Derrick Pitts at the Franklin Institute in Philadelphia. We got to look through a pretty sweet telescope on the roof.<\/li>\n<li>In 4th grade, my science teacher hosted an astronomy night. It was temporarily cancelled due to weather but then was back on at the last minute. The next morning, I told my homeroom teacher that I went to the astronomy night and she looked really concerned because she thought it was cancelled. I remember this because she always seemed worried about everything.<\/li>\n<li>When I was 11 years old, I went to an Audubon camp in Maine in August and saw my first meteor shower. I&#8217;m guessing it was the Perseids, and it was amazing.<\/li>\n<li>In March of 1997 when my family was on vacation in Colorado, a partial lunar eclipse occurred while the Comet Hale-Bopp was especially bright, and I&#8217;m pretty sure we spotted it. At the same time, Hanson&#8217;s &#8220;MMMBop&#8221; was a popular song, and Andy Signore wrote a parody song honoring this and published on the back of the creatively-named <em>S&#8217;Edition,<\/em> a parody of <em>The Edition,<\/em> our school&#8217;s paper.<\/li>\n<li>I <a href=\"http:\/\/wysz.com\/wyszdom\/2008\/08\/perseids\/\">saw the Perseids again<\/a> last summer.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"<p>Tomorrow night I&#8217;ll finish my Android trial, and I&#8217;m honestly not sure which device my SIM card will be sitting in at 7:00.
