How to Photograph a Moonrise and Moonset

1 Comment

Want to learn how to predict and photograph a moonrise or moonset? Here’s a helpful 5-minute video on just that by photographer Matthew Saville of Nature TTL.

Every month there is a full moon, and this is the perfect time to capture the moon on camera. The moon will rise and set perfectly with sunrise and sunset, meaning that you have (potentially) beautiful colors in the sky to make an impactful lunar image.

To help with moonrise and moonset photography, there are a number of apps that will allow you to utilize augmented reality to “see” the position of the moon via your smartphone.

Saville recommends 3 apps in particular: PhotoPills, Sun Surveyor, and The Photographer’s Ephemeris. Each of these apps will show you the precise positioning of the moon, allowing you to line-up a composition in advance so that you aren’t relying on “getting it right on the night.”

Sometimes you may need to take a number of exposures of the scene, blending them together later during post-production, to ensure a properly exposed moon and landscape. These are all important considerations, but if you do mess up the first time around then you can try again next month!

Check out the full video above to see tips from Saville about how to compose a successful lunar landscape photo, and subscribe to the Nature TTL channel for weekly nature photography tutorials.

Calculating Like It’s 1962

2 Comments and 3 Shares

We sometimes forget that the things we think of as trivial today were yesterday’s feats of extreme engineering. Consider the humble pocket calculator, these days so cheap and easy to construct that they’re essentially disposable. But building a simple “four-banger” calculator in 1962 was anything but a simple task, and it’s worth looking at what one of the giants upon whose shoulders we stand today accomplished with practically nothing.

If there’s anything that [Cliff Stoll]’s enthusiasm can’t make interesting, we don’t know what it would be, and he certainly does the job with this teardown and analysis of a vintage electronic calculator. You’ll remember [Cliff] from his book The Cuckoo’s Egg, documenting his mid-80s computer sleuthing that exposed a gang of black-hat hackers working for the KGB. [Cliff] came upon a pair of Friden EC-132 electronic calculators, and with the help of [Bob Ragen], the engineer who designed them in 1962, got one working. With a rack of PC boards, cleverly hinged to save space and stuffed with germanium transistors, a CRT display, and an acoustic delay-line memory, the calculators look ridiculous by today’s standards. But when you take a moment to ponder just how much work went into such a thing, it really makes you wonder how the old timers ever brought a product to market.

As a side note, it’s great to see the [Cliff] is still so energetic after all these years. Watching him jump about with such excitement and passion really gets us charged up.

Thanks to [Mark] and [Jerrad] for the near-simultaneous tips on this one.

World's cheapest electricity is Mexican solar power

1 Share

Electricity here in Los Angeles is 17.8 cents per kilowatt hour (kWh). Not far away, Mexicans get solar electric for one-tenth the price. And by 2019, the price could drop to 1¢/kWh.

From Electrek:

Soon we’re going to have to confront new questions as solar power costs less than anything seriously considered before, and will offer new opportunities never thought of before. What will we do with all of this cheap energy? How do we move from fossil systems toward solar sources without destroying the social fabric of those dependent on revenue from gas and coal? How will our post scarcity society continue to advance? It’s going to be more difficult to live up to the potentials of solar and ‘free energy’ than we think.

texnessa: mediamattersforamerica: WOW. Watch these 3 minutes...

texnessa:

mediamattersforamerica:

WOW. Watch these 3 minutes from Dallas sportscaster Dale Hansen talking about what Trump doesn’t understand about the national anthem and the right to protest. Compare this to any right-wing media whining and that’s why this is one to remember.

Dale Hansen is a fucking treasure.  He admitted he was a childhood victim of sexual abuse in the hopes that it would encourage others to come forward and seek help. He has been an ardent supporter of scholar-athletes and of gay players in the NFL and of trans athletes.

“I’m not always comfortable when a man tells me he is gay; I don’t understand his world. But I do understand that he is part of mine.”

Changes in Password Best Practices

2 Comments and 23 Shares

NIST recently published their four-volume SP800-63-3 Digital Identity Guidelines. Among other things, they make three important suggestions when it comes to passwords:

  1. Stop it with the annoying password complexity rules. They make passwords harder to remember. They increase errors because artificially complex passwords are harder to type in. And they don't help that much. It's better to allow people to use pass phrases.

  2. Stop it with password expiration. That was an old idea for an old way we used computers. Today, don't make people change their passwords unless there's indication of compromise.

  3. Let people use password managers. This is how we deal with all the passwords we need.

These password rules were failed attempts to fix the user. Better we fix the security systems.

A meeting recently:
Developer Team: Our passwords require special characters, and max out at 30 characters.
Me: Why on EARTH did you do any of that? Why do you have a max?
Devs: Because ... it's hard to remember something long? How long do you want it to be?
Me: ... Get rid of the max. Get rid of the special characters.
CIO: Wait. Why do we have passwords at all? Can we link to google/linkedin/facebook and make it their problem? We are not in the security business.
Devs: Yes!
