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.

ISO 12233 Test Chart

Saved by uncleflo on January 6th, 2019.

In 2000, the International Standards Organization adopted ISO Standard 12233: Photography -- Electronic still-picture cameras - Resolution measurements for the measurement of camera resolution. This standard is protected by copyright, but the design of the associated test chart seems not to be protected; its description has been available on the Web in an Excel spreadsheet. I have semi-manually converted this to an Adobe Illustrator file which is displayed here. In 2014 and again in 2017, the ISO revised the standard and the chart below was replaced by several new ones. Those new charts are not available here. In principle, you should be able to print this chart and perform resolution tests on your camera. The reality isn't that simple; there are lots of subtleties having to do with focus distance, quality and contrast of your printer, evenness of illumination, surface reflections, etc.

An Introduction to Lean Canvas – Steve Mullen – Medium

Saved by uncleflo on January 4th, 2019.

As an entrepreneur, one of the most important tasks you can perform is getting your idea(s) out from your head into a tangible format so that you can communicate that with others. In the past, this usually meant a well-researched business plan, that would usually take weeks (more like months) to create. I turn to the Lean Canvas to help me quickly formulate possible business models, product launches, campaigns and variations of, and communicate this with my stakeholders for my Lead Flow Method work. Having the Lean Canvas as a visual guide made this part “communicating the model/idea” so much more effective — and I think the most valuable function of the tool. The problem with business plans for startups & entrepreneurs are that they’re a waste of time, don’t get me wrong a well-researched business plan is important but only at the right stage of your business (usually when you’re in growth/investment). This quote from Steve Blank sums up this point in case: “Business Plan: a document investors make you write, that they don’t read”. The key fundamental to Lean methodology is the elimination of waste — this includes time, processes, inventory and more. So as a lean startup you need a quicker way to get ideas out of your head, you need to stay lean & avoid waste — so, it’s time to introduce Lean Canvas.

Linux Daemon Writing HOWTO

http://www.netzmafia.de/skripten/unix/linux-daemon-howto.html

Saved by uncleflo on January 4th, 2019.

A daemon (or service) is a background process that is designed to run autonomously,with little or not user intervention. The Apache web server http daemon (httpd) is one such example of a daemon. It waits in the background listening on specific ports, and serves up pages or processes scripts, based on the type of request. Creating a daemon in Linux uses a specific set of rules in a given order. Knowing how they work will help you understand how daemons operate in userland Linux, but can operate with calls to the kernel also. In fact, a few daemons interface with kernel modules that work with hardware devices, such as external controller boards, printers,and PDAs. They are one of the fundamental building blocks in Linux that give it incredible flexibility and power. Throughout this HOWTO, a very simple daemon will be built in C. As we go along, more code will be added, showing the proper order of execution required to get a daemon up and running.

What You Need to Know About Watermakers - Sail Magazine

https://www.sailmagazine.com/diy/need-know-watermakers

Saved by uncleflo on January 4th, 2019.

With a watermaker aboard, the days of rationing freshwater can come to an end! Photo by Discovery Yachts Water may be essential to life, but it can also be a pain aboard a sailboat. For one thing, it weighs a tremendous amount, and tankage can take up a good deal of space, especially aboard a smaller cruising boat. Water tanks can also be a pain to top off, especially in a remote foreign port. Not only do you often have to pay for the stuff, but there is the fear of its containing both organic and inorganic contaminants. Fortunately, in recent years sailors have been able to enjoy the benefits of modern watermakers that in many ways do for water stowage what GPS did to navigation: make a whole world of problems go away with the push of a button. That said, like GPS, watermaker technology is not entirely a no-brainer. In addition to taking care of your system—running and rinsing it regularly, pickling it with biocides if you can’t, and changing the filters regularly according to the manufacturer’s recommendations—it’s important to recognize that despite their similarities, there are also some basic differences between the many models on the market that have important implications in terms of how they are operated.

Water systems - Jones Boatyard

Saved by uncleflo on January 4th, 2019.

Most enclosed boats will have some kind of water system on board, ranging from a single manual pump operated tap to a system featuring hot and cold water with mixer taps and showers. Marine plumbing can be a daunting subject but most pleasure craft designed for river use have surprisingly similar water systems and understanding the function of just a few key common components can really help to gain a good understanding of marine plumbing. Unlike domestic plumbing where water pressure is generally created by gravity, boats require an electric pump to generate water pressure as tanks are often level with or below the outlets they serve. The pump is therefore the heart of the system and works by cycling on and off to maintain the desired pressure and a good flow when you open a tap. Most pumps are switched on and off automatically via a pressure switch inside the pump, though some smaller pumps rely on micro switches within the taps themselves. Pumps do differ in the pressure they provide (usually in PSI) and the flow rate (usually in GPM or LPM). The size of your boat, the number of outlets the pump will serve and the complexity of the water system will dictate which pump you will need.

GraspingTech | How to Mount an NFS Share Using a Windows 10 Machine

Saved by uncleflo on January 3rd, 2019.

Mounting an NFS (Network File System) share using a Unix-like operating system is pretty straight forward. But how do you mount an NFS share of a UNIX system from a Windows 10 machine? Keep reading to find out how. With that said let’s install the Services for NFS feature and mount an NFS share. The first thing we need to do is install the NFS Client which can be done by following the steps below: With the default options you will only have read permissions when mounting a UNIX share using the anonymous user. We can give the anonymous user write permissions by changing the UID and GID that it uses to mount the share.

Mounting NFS on a Windows Client

Saved by uncleflo on January 3rd, 2019.

Complete the following steps to mount NFS on a Windows client: The UID and GID values are set in the Windows Registry and are global on the Windows NFS client box. This solution might not work well if your Windows box has multiple users who each need access to NFS with their own permissions, but there is no obvious way to avoid this limitation. To set up the Windows NFS client, mount the cluster, map a network drive, and configure the user ID (UID) and group ID (GID). The Windows client must access NFS using a valid UID and GID from the Linux domain. Mismatched UID or GID will result in permissions problems when MapReduce jobs try to access files that were copied from Windows over an NFS share. Because of Windows directory caching, there may appear to be no .snapshot directory in each volume's root directory. As a workaround, force Windows to re-load the volume's root directory by updating its modification time (for example, by creating an empty file or directory in the volume's root directory).

2 Sentiment analysis with tidy data | Text Mining with R

https://www.tidytextmining.com/sentiment.html

Saved by uncleflo on December 23rd, 2018.

In the previous chapter, we explored in depth what we mean by the tidy text format and showed how this format can be used to approach questions about word frequency. This allowed us to analyze which words are used most frequently in documents and to compare documents, but now let’s investigate a different topic. Let’s address the topic of opinion mining or sentiment analysis. When human readers approach a text, we use our understanding of the emotional intent of words to infer whether a section of text is positive or negative, or perhaps characterized by some other more nuanced emotion like surprise or disgust. We can use the tools of text mining to approach the emotional content of text programmatically, as shown in Figure 2.1.

Term Frequency and Inverse Document Frequency (tf-idf) Using Tidy Data Principles

https://cran.r-project.org/web/packages/tidytext/vignettes/tf_idf.html

Saved by uncleflo on December 23rd, 2018.

A central question in text mining and natural language processing is how to quantify what a document is about. Can we do this by looking at the words that make up the document? One measure of how important a word may be is its term frequency (tf), how frequently a word occurs in a document. There are words in a document, however, that occur many times but may not be important; in English, these are probably words like “the”, “is”, “of”, and so forth. We might take the approach of adding words like these to a list of stop words and removing them before analysis, but it is possible that some of these words might be more important in some documents than others. A list of stop words is not a sophisticated approach to adjusting term frequency for commonly used words. Another approach is to look at a term’s inverse document frequency (idf), which decreases the weight for commonly used words and increases the weight for words that are not used very much in a collection of documents. This can be combined with term frequency to calculate a term’s tf-idf, the frequency of a term adjusted for how rarely it is used. It is intended to measure how important a word is to a document in a collection (or corpus) of documents. It is a rule-of-thumb or heuristic quantity; while it has proved useful in text mining, search engines, etc., its theoretical foundations are considered less than firm by information theory experts.

tf–idf - Wikipedia

https://en.wikipedia.org/wiki/Tf%E2%80%93idf

Saved by uncleflo on December 23rd, 2018.

In information retrieval, tf–idf or TFIDF, short for term frequency–inverse document frequency, is a numerical statistic that is intended to reflect how important a word is to a document in a collection or corpus. It is often used as a weighting factor in searches of information retrieval, text mining, and user modeling. The tf–idf value increases proportionally to the number of times a word appears in the document and is offset by the number of documents in the corpus that contain the word, which helps to adjust for the fact that some words appear more frequently in general. Tf–idf is one of the most popular term-weighting schemes today; 83% of text-based recommender systems in digital libraries use tf–idf. Variations of the tf–idf weighting scheme are often used by search engines as a central tool in scoring and ranking a document's relevance given a user query. tf–idf can be successfully used for stop-words filtering in various subject fields, including text summarization and classification. One of the simplest ranking functions is computed by summing the tf–idf for each query term; many more sophisticated ranking functions are variants of this simple model.

If I ask you “Do you remember the article about electrons in NY Times?” there’s a better chance you will remember it than if I asked you “Do you remember the article about electrons in the Physics books?”. Here’s why: an article about electrons in NY Times is far less common than in a collection of physics books. It is less likely to stumble upon the “electron” concept in NY Times than in a physics book. Let’s consider now the scenario of a single article. Suppose you read an article and you’re asked to rank the concepts found in the article by importance. The chances are you’ll basically order the concepts by frequency. The reason is simply that important stuff would be mentioned repeatedly because the narrative gravitates around them. Combining the 2 insights, given a term, a document and a collection of documents we can loosely say that:importance ~ appearances(term, document) / count(documents containing term in collection).

DMARC - Wikipedia

https://en.wikipedia.org/wiki/DMARC

Saved by uncleflo on December 23rd, 2018.

DMARC (Domain-based Message Authentication, Reporting and Conformance) is an email-validation system designed to detect and prevent email spoofing, the use of forged sender addresses often used in phishing and email spam. It is built on top of two existing mechanisms, Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM). It allows the administrative owner of a domain to publish a policy in their DNS records to specify which mechanism (DKIM, SPF or both) is employed when sending email from that domain; how to check the From: field presented to end users; how the receiver should deal with failures - and a reporting mechanism for actions performed under those policies. A DMARC policy allows a sender's domain to indicate that their emails are protected by SPF and/or DKIM, and tells a receiver what to do if neither of those authentication methods passes – such to reject the message or quarantine it. The policy can also specify how an email receiver can report back to the sender's domain about messages that pass and/or fail.[2]

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.
