Submission + - What did /.'ers do to experience the 2017 Total Solar Eclipse?

xmas2003 writes: /. posted a few days before the August 21st, 2017 Total Solar Eclipse but we haven't seen any followup. What did /.'ers do to experience this rare incredibly cool event and how did it turn out?

SmarterEveryDay Destin gets great geek cred for watching the ISS transit the eclipsed sun while we were fortunate to have an incredible experience on 40 acres of farmland watching the Total Solar Eclipse near Tryon, Nebraska — here's a complete video of the totality event from the middle of nowhere.

While the pics/video are cool, the real-life experience of actually being there in person is even 100X better — highly recommend you try to attend a future total solar eclipse!

Submission + - Webcam-Equipped Remote-Controllable Halloween Haunt

xmas2003 writes: Timothy asked yesterday what /.'ers are doing for Halloween and said "Maybe one year Alek Komarnitsky will switch to Hallowe'en instead of Christmas, and offer a webcam-equipped remote-controllable haunt." Turns out he actually has been doing that since 2005 ... and his Controllable Halloween Decorations allow you to turn 10,000 lights ON & OFF plus inflate/deflate the giant Frankenstein, Pumpkins, Grim Reaper, Skull, Headless Horseman, SpongeBob SquarePants, and Homer Simpson — D'OH! ;-)

Submission + - Followup: Ultraviolet Vision after Cataract Surgery (komar.org)

xmas2003 writes: "Several months ago, I posted to /. about being able to see ultraviolet light after cataract surgery. While a lot of the discussion whimsically discussed the best way for "Captain UV" or "UltraMan" to use this "super-power", there were some people who were skeptical or (incorrectly) said this is Tetrachromatic vision. I've subsequently done more testing using an Oriel Instruments MS257 Monochromator and was able to see color down to 350nm — below the usual ~400nm limit of the visual spectrum. It's also easily demonstrable with a pair of 400nm and 365nm UV flashlights.

Some /.'ers who also have UV vision commented this can be quite annoying at black-lit Disney Rides, Halloween Haunted Houses, etc. Fortunately for me, it's just an interesting oddity so far. Along those lines, some interesting related stories about using UV vision during World War II and Star Gazing. Finally, many/most people end up getting vision debilitating cataracts, so my experience having a Crystalens implanted after cataract surgery may be informative."

Submission + - Linux-Powered Christmas Display Puts Rudolph to Sh (komar.org)

xmas2003 writes: "Over at Linux.com, Zonker writes about Alek's Controllable Christmas Lights for Celiac Disease. This annual Internet tradition uses a hi/low-tech combo of LAMP'ed Redhat Web Servers, a 7+ year old Thinkpad running Unbuntu for the X10 control, and an old-school webpage design that could be politely described as Web 0.0 — wait until you see the animated cursor — D'OH! The site is free (and totally fun) as it also raises awareness and donations for Celiac Disease — over $70,000 to the University of Maryland.

Nifty pictures of the crazy christmas display can be seen on the Christmas Blog (notice Clifford Stoll's "The Cuckoo's Egg" in post #220) plus watch videos of it in action with comedic history. Nothing quite says Christmas like a giant HULK inflatable wearing a Santa Hat ... along with three wise men of Elmo, SpongeBob, and Homer Simpson — D'OH! The Slashdot Effect of turning 21,000 Christmas lights ON & OFF this evening should provide quite a Christmas Eve show to Alek's neighbors ... and also the International Space Station."

Submission + - Able to see Ultraviolet Light after Cataract Surge (komar.org) 2

xmas2003 writes: "I recently had Cataract Surgery with a Crystalens implant. With my cloudy yellowing (UV-filtering) natural lens removed, I see the world in a new light (more on that in a moment) as everything is brighter and colors are more vivid ... plus in focus. As a typical /. reader, I've been myopic since childhood, so it's wonderful not to have to wear glasses/contacts for distance.

One interesting oddity is that I can now see Ultraviolet light — it seems that there are a few people who have photoreceptors sensitive below 400nm into the UV spectrum. I've done some testing with a Black Light and UV filter to confirm this but would love to do more conclusive testing such as using a Monochromator — anyone in the Boulder, Colorado area have access to one? And any suggestions from /. readers on how I can further explore this phenomena?

So while "I can't see dead people", I guess I have a "superpower" ... although I'm not sure a middle-aged suburbanite Dad should don purple tights and cape to become a crime-fighter! ;-)"

Submission + - Consumer webcams with high quality sensors

xmas2003 writes: Since 2005, I've had a live webcam watching my grass grow — another is currently watching a bird nest on my front door — five babies! While I appreciate the 802.11g wireless and Pan/Tilt/Zoom (10x optical) of the 5 year old D-Link DCS-6620g, it has issues, especially image quality. I've investigated getting a new webcam, but except for high-end/security-related gear from companies such as Axis, there doesn't seem to be much improvement in the consumer space as most offerings are just cheaper and USB connected for tethered video conferencing, etc.

I have an 18 Megapixel Canon 7D DSLR that shoots gorgeous 1920x1080x30p hi-def video. While I don't expect that in a consumer webcam, their recently released T2i uses the same chip and sells for $800. And heck, point-n-shoots are a couple of hundred bucks and now many cell phones have cameras built in, so there's plenty of low power speedy CPU's in small packages these days to handle the signal processing.

So why hasn't someone taken a sensor with good image quality sensor, downsized to around 1024x768, and put it in a PTZ webcam package with 802.11n wireless for around $500?

Submission + - Gmail, SPF, and Broken Email Forwarding

alek writes: I recently stopped getting Email from a friend ... which turns out to be related to his use of SPF records and my forwarding to gmail. This "lost Email problem" may get worse with Google implementing Domain Keys.

Background: Like many people, I have me@mydomain.com as my public facing Email address. When Email comes into my server, I forwarded it to me@gmail.com. But since my friend has published SPF (Sender Policy Framework) records that say only his server is allowed to send Emails for friend@frienddomain.com, gmail apparently rejects (silently buries actually!) the Email since it is forwarding through my server. Please note that this is exactly what SPF is designed to prevent — spammers from sending Emails with your address — but it breaks forwarding and has other problems.

What's *really* strange is that if I look at the raw sendmail logs on my server, the Email from friend@frienddomain.com comes in, and is forwarded to gmail ... with an "OK" as the response — i.e. the gmail MTA doesn't reject the message as it ideally should. However, the Email then disappears — it's not even in my gmail spam filter ... so there is no trace of it at all. If my friend sends directly to me@gmail.com, it shows up ... since his domain sends directly and the SPF test is passed. Note that on my gmail account, I associate me@mydomain.com with my me@gmail.com account ... so perhaps there should be a recipient test applied before SPF is tested on the sender ... although this arguably defeats the purpose of SPF.

The logical solution is to configure sendmail on my server to do Sender Rewriting — anyone have an easy FAQ to do this? But many people/domains aren't doing this ... and my Email forwarding to gmail is quite common, so I'm surprised that this issue hasn't gotten more attention. Is there another solution?
