How to Test Your Lens | B&H Explora

https://www.bhphotovideo.com/explora/photography/tips-and-solutions/how-to-test-your-lens

Saved by uncleflo on January 6th, 2019.

So, you just bought a shiny, new, and maybe expensive, lens for your camera, and being the savvy consumer, you did your homework. You pored over customer reviews on the B&H Photo website, read online reviews splattered all over the Internet, grabbed a copy of every photo magazine that reviewed the lens, bookmarked dozens of websites, and now have the lens’s MTF curve charts burned into your retinas. Now, your lens is here and it is time to go out shooting. Honestly, not a problem. Your lens should be as good as it can be and, as photographers, we want to take photos. So, stop reading and go out and make some photographs! Still here? OK, let me tell you why you might want to test that lens yourself. The main reason is that even with today's precision computer-controlled manufacturing techniques, there are variations in each and every lens that rolls off an assembly line. This means that some examples will be better than others. Some lenses will be outstanding and others will make you wonder if all of those glowing reviews you read online were completely bogus.

Sophie Hellyer - What Are You Made of? // The Sustainable Swimwear Guide

https://www.sophiehellyer.com/blogposts/2018/1/31/what-are-you-made-of-the-sustainable-swimwear-guide

Saved by uncleflo on December 20th, 2018.

I realise when I first released this post, it was January, a time of year that not everyone is throwing themselves into water without a wetsuit. A lot of you have been asking about sustainable swimwear options again over the past month with this never-ending heatwave we are having, so I thought I’d update and repost this guide. With environmental issues becoming much more prominent in the mainstream media, a quick google into the textiles and fashion industries will provide you with endless reasons to choose slow fashion. If you didn't follow Fashion Revolution and the #whomademyclothes movement go and check it out, alongside the documentary The True Cost. The price is often more because these companies pay workers a fair living wage, and source sustainably grown and produced materials. I've been trying to buy everything I wear consciously and not fall into the consumerism trap too often (although I'm occasionally slip up and find myself on the high street, damn those glittery topshop dinosaur socks). I try to follow the guide lines:

London housing crisis extends to the water

https://edition.cnn.com/2016/07/26/world/london-water-crisis/index.html

Saved by uncleflo on December 20th, 2018.

London vies with Hong Kong and Monaco for the unenviable title of the world's most expensive city for housing. The average house price in the English capital is now nearly £600,000 ($787,000), and a study from the charity Shelter found just 43 properties affordable to people on an average income. Several of these properties were houseboats. Life on London's 100-mile network of canals, or 42-mile stretch of the River Thames, has become a popular option for beleaguered citizens, and such homes can cost as little as £20,000 ($26,500). But as more people swap apartments for houseboats, the popular, romantic vision is giving way to a harsh reality.

Zoom H6 Review: The Ultimate Podcasting Recorder?

https://www.thepodcasthost.com/equipment/recorders/zoom-h6-review/

Saved by uncleflo on December 20th, 2018.

Zoom are the masters of the digital recorder, and the Zoom H6 is currently their marquee model. We’ve been using the H4 and H5 recorders for a few years here at The Podcast Host, and both are superb bits of kit. But we treated ourselves to an early Christmas present in the shape of the H6, and I’d been looking forward to getting a good look at it. I’ve heard enough glowing reviews of the H6 from well respected podcasters and audio engineers to know that there’s no doubt over its quality. So, in this review, we’ll go over what makes it such a good recorder. But we’ll also look at the reasons why it might be overkill for some podcasters, depending on their own individual requirements.

Fundamentals of Restoration Projects

http://www.docksidereports.com/fundamentals_of_restoration_proj.htm

Saved by uncleflo on November 29th, 2018.

During my three decades as a marine surveyor, I've always been amazed about two aspects of restoring old boats what, in the marine trade, is known as a refit. First is that the people who can best afford to do them, usually don't. Followed by those who can't afford such projects are usually the ones that attempt them. Such projects usually go wrong because the owner failed to appreciate the costs, and to estimate them in advance. There are no good deals on fixer uppers with boats. There is just expensive and more expensive. Money is the name of the game, and if you haven't got it, then it's a mistake to think that you can do a refit on the cheap.

By reporting your own positions, MarineTraffic will be able to display your vessel on the Live Map. Visibility: Real-time vessel positions displayed on the MarineTraffic Live Map are extremely useful to a wide spectrum of users closely-related to the shipping industry one way or the other. To name a few, ship owners, agents, pilots, tug operators, port authorities, crews' families and friends, passengers, cargo handlers or recipients, brokers, leisure boaters, sailing racers, ship chandlers, bunkering companies, yacht charterers or brokers may have a reason to monitor the positions of your vessel. The list of interested parties is unlimited while the numbers speak for themselves; the visibility of the MarineTraffic website is such that the number of visitors per day well exceeds the half a million mark! Safety: Although MarineTraffic is not intended to be used as a safety tool, there are many cases where making your position widely known could enhance your safety at sea. Making your position known to the public may be complementary to the official means of distress reporting (such as EPIRB or DSC radio) and may help in Search & Rescue (SAR) procedures where the position of the vessel cannot be acquired by other means. Historical data: MarineTraffic stores historical data in its database. Historical data regarding the past movements of your vessel could be accessed for many reasons; such as just for fun or recollection, for statistical reasons, for analyzing tracks in comparison to weather conditions, for accident investigation etc. Consider it as an online log of yours!

Pietà (marble sculpture)

https://www.khanacademy.org/humanities/renaissance-reformation/high-ren-florence-rome/michelangelo/v/michelangelo-piet-1498-1500

Saved by uncleflo on October 28th, 2018.

Michelangelo, Pietà, marble, 1498-1500 (Saint Peter's Basilica, Rome) Speakers: Dr. Beth Harris and Dr. Steven Zucker. The Pietà was a popular subject among northern european artists. It means Pity or Compassion, and represents Mary sorrowfully contemplating the dead body of her son which she holds on her lap. This sculpture was commissioned by a French Cardinal living in Rome. Look closely and see how Michelangelo made marble seem like flesh, and look at those complicated folds of drapery. It is important here to remember how sculpture is made. It was a messy, rather loud process (which is one of the reasons that Leonardo claimed that painting was superior to sculpture!). Just like painters often mixed their own paint, Michelangelo forged many of his own tools, and often participated in the quarrying of his marble -- a dangerous job. When we look at the extraordinary representation of the human body here we remember that Michelangelo, like Leonardo before him, had dissected cadavers to understand how the body worked. - Created by Beth Harris and Steven Zucker.

We've finally done it: Fstoppers has moved over to a new 10 Gb/second network and server and it is incredibly fast. Let me show you what we did and how you can create your own 10 Gb/s network for a fraction of the price. For the past four years we have been using a Synology NAS (network attached storage) device to work from and to backup all of our photo and video content. It has served us well but as we hire more people, and as we begin shooting videos in 4K, it has been filling up and slowing down. It was time for us to upgrade.

Ricoh’s Theta V Is Sharper and More Powerful, But Let's Talk About 360 Video...

https://gizmodo.com/ricoh-s-theta-v-is-sharper-and-more-powerful-but-lets-1798544146

Saved by uncleflo on October 8th, 2018.

Ricoh has been in the 360-degree camera game for a long time—way before johnny-come-latelies like Samsung and Nikon. Things started back in 2013 with the original Ricoh Theta and now four years later, the company is back with the $430 Theta V. New features include 4K video and spatial audio capture, however, even with all those bells and whistles I’m having a hard getting excited about Ricoh’s new camera. The problem isn’t with the camera itself, it’s the medium. As I think back on the thousands of videos I watched since 2013, not a single 360 video sticks out in my a something truly memorable. Even when I dig a little deeper and consider things like Casey Neistat’s video about droneboarding or a tour through California Extreme with Steve Lin and Drew Scanlon, the source of the white blinking guy meme, I can’t help but think that both of these clips would have been better as boring flat clips.

3 Biases That Hijack Performance Reviews, and How to Address Them

https://hbr.org/2018/06/3-biases-that-hijack-performance-reviews-and-how-to-address-them

Saved by uncleflo on June 22nd, 2018.

When we talk about bias, we often tie it to acts of discrimination or prejudice. But according to cognitive science, everybody, by virtue of having a brain that’s constantly seeking efficiency, is biased in some way — and not all biases make us actively malicious. The key is how we manage our biases. While biases can affect any of an organization’s talent decisions, they can be especially harmful when it comes to diversity and inclusion efforts. And there is perhaps no setting that shapes careers, salaries, and lives like annual performance evaluations. In a recent performance management summit we ran with over 100 large organizations, 57% of them said they weren’t taking any actions to address bias in performance reviews. One reason why may be a lack of shared language: In order to address biases, you first have to be able to label them. Research has found that several biases come up again and again when managers are evaluating a team member.

In-Depth Diving With A Vintage Tornek-Rayville

https://www.hodinkee.com/articles/vintage-tornek-rayville-diving-in-depth

Saved by uncleflo on June 5th, 2018.

A mile offshore from San Benedicto, a volcanic island in the Eastern Pacific, and 75 feet deep, I raise my GoPro to take a selfie. I want to preserve this moment, not only because it’s the first dive of what promises to be a truly memorable adventure, but also because on my wrist is a very rare watch. I’m wearing a vintage Tornek-Rayville TR-900, a watch built by Blancpain for the United States Navy in the 1960s, and this is likely the only surviving one that has been fully serviced and suitably sealed for modern dive use. It’s a photo for bragging rights, or perhaps an epitaph, should I be the one to lose or flood such a rare horological treasure.

Human Body Heat as a Source for Thermoelectric Energy Generation

http://large.stanford.edu/courses/2016/ph240/stevens1/

Saved by uncleflo on May 31st, 2018.

The idea of converting human body heat into a form of usable energy has been targeted by scientists for years. A resting human male gives off roughly 100-120 Watts of energy. A very small fraction of this can be utilized by a thermoelectric device to power wearable devices. As an example, Seiko's Thermic Watch managed to capture continuous a charge at only one microwatt, so there is certainly a viable market that has not yet blossomed. It being known that 80% of a typical human's body power is given off as heat, current technologies can only produce a few milliwatts of energy. This is not nearly enough to charge your iPhone at a power input of roughly 5 watts, and unfortunately this sort of efficiency may never be possible.

Securely Hash Passwords with PHP

https://jonsuh.com/blog/securely-hash-passwords-with-php/

Saved by uncleflo on December 27th, 2017.

PHP 5.5+ now comes baked with a password_hash function to generate secure, one-way hashes along with a password_verify function to match a hash with the given password—If you’re a PHP developer, you should always be securely storing user passwords, no excuses. Developers have a huge responsibility when handling and storing user-sensitive information, such as a password. We should take extra precaution and the necessary steps to make sure the user’s data is safe and secure*. *Please keep in mind the following implementation is only part of the problem since it handles the data once the web server receives it; however, it does not address the other issue of securely sending the sensitive data over-the-air from the browser to the server, which is why a valid SSL certificate is necessary.

Performance and Security of ECDSA

https://koclab.cs.ucsb.edu/teaching/ecc/project/2015Projects/Levy.pdf

Saved by uncleflo on July 10th, 2017.

Digital signatures are used world wide to verify the authenticity of messages and confirm that they have not been altered in transmission. The Digital Signature Algorithm (DSA) is a Digital Signature Standard for the Federal Information Processing Standard and uses public key cryptography. The Elliptic Curve Digital Signature Algorithm (ECDSA) is a version of DSA using elliptic curves. In this paper, I will introduce ECDSA and discuss its key generation, signing, and verifying procedures. Then, I will compare this algorithm to the RSA digital signature algorithm and discuss its various advantages and drawbacks. Finally, I will discuss the security of ECDSA and attacks that can break it.

Saved by uncleflo on July 10th, 2017.

This paper introduces a new cryptographic library, NaCl, and explains how the design and implementation of the library avoid various types of cryptographic disasters suffered by previous cryptographic libraries such as OpenSSL. Specifically, this paper analyzes the security impact of the following NaCl features: no data flow from secrets to load addresses; no data flow from secrets to branch conditions; no padding oracles; centralizing randomness; avoiding unnecessary randomness; extremely high speed; and cryptographic primitives chosen conservatively in light of the cryptanalytic literature.

Saved by uncleflo on April 12th, 2017.

Alice Phoebe Lou's fiercely independent approach to her music has given the singer songwriter a creative confidence that shines through in her captivating vocals and stripped back music. Having developed her bluesy, folk sound busking on the streets of Berlin, Alice has caught the ears of a community of music lovers the world over with her honest storytelling and raw, beautiful voice. Alice grew up on a mountainside in South Africa listening to her parent's records and indulging her love of theatre, arts and music at a local Waldorf school; a formative time that nurtured her independence and desire to experience music of all styles. This multi-faceted creative upbringing mixed with Alice's natural wanderlust and in 2010, 16-year-old Alice made her first journey to Europe during her summer break from school. Inspired by watching fire dancers in Paris, she began to perform likewise to get enough money to fund her travelling.
