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.

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.

How TF-IDF algorithm determines keyword importance - arbitrue Blog

https://www.arbitrue.com/blog/tf-idf-algorithm-for-keyword-importance/

Saved by uncleflo on December 23rd, 2018.

There are many tools in the developer’s toolbox when it comes to automatic data extraction. A good example is TF-IDF algorithm (Term Frequency – Inverse Document Frequency) which helps the system understand the importance of keywords extracted using OCR. Here’s how TF-IDF can be used for invoice and receipt recognition. In this article we focus on other techniques in order to make this text file “understandable” to a computer. For this purpose, we must delve into the world of NLP or Natural Language Processing. We will focus mainly on how we can transform our file of raw text into a format that will easily be understandable by our algorithm. In a nutshell, TF-IDF is a technique for understanding how important a word is in a document which is often used as a weighting factor for numerous use cases. TF-IDF takes under consideration how frequent a word appears in a single document in relation to how frequent that word is in general. Search engines can use TF-IDF to determine which results are the most relevant for a search query.

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.

Weighting words using Tf-Idf - NLP-FOR-HACKERS

https://nlpforhackers.io/tf-idf/

Saved by uncleflo on December 23rd, 2018.

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).

How to Make a Concrete Garden Statue at Home

Saved by uncleflo on November 29th, 2018.

A few years ago I decided to order a Buddha garden statue mold online because I wanted to start making these statues and selling them. They are fairly easy to make they just require a little hard work and there are a few things that you can do which help to improve the quality of the finished product. Firstly though I will tell you the things which you will need to make the statue. You will need a mold which you can buy online or you can make your own. I will be putting a hub up soon which shows you how to make your own. You will also need some cement, some sand , some pea gravel, water, a container to mix your concrete in, a spade or something that you can mix your concrete with, a rubber mallet, some silicone spray and some carpet. You can also find a product which is called concentrated plasticiser. I have found that this product helps to reduce air bubbles and also makes the statues stronger and less likely to crack.

Mike Curtis over at hdforindies.com recently posted a brilliant rant/advice list called 10 Things Not To Do, detailing his "don't" list for indie/digital filmmakers. Inspired by this, I have attempted to concoct my own finger-wagging list for the audio sound of things, for filmmakers as well as other producers, directors and DP's. (Edit: I'll preface this by stating this is mainly based on my professional experience, the majority of which has been shorts, both DV and S16; indie DV and HD features; corporate and industrials; documentaries and some reality TV. Additionally, much of what I've come up with is echoed to an extent in The Letter, which you should already have framed on your wall:)

Wireless Tethered Shooting With Your Canon DSLR Via Wi-Fi

http://marcschultz.com/blog/wireless-tethered-shooting-canon-dslr/

Saved by uncleflo on November 29th, 2018.

If you have followed my blog over the past few years, you may have read some of the articles I wrote on the subject of tethered shooting with your Canon DSLR together with either a tablet or smartphone. I love tethered shooting with portable devices, mainly because they are small and easy to carry around, I can trigger the camera remotely and I can see a larger review image on the remote screen afterwards. In fact, my most widely read blog post is one I wrote in November 2013 titled Tethered Shooting With Your Canon DSLR And Android Tablet. But since then, a lot has changed. Many of the newer Canon DSLR bodies now offer Wi-Fi, such as the Canon 6D, 80D, 70D, 1DX Mark II (via the Canon WFT-E8 adapter), all versions of the Rebel T6, and the 7D Mark II (via a recently released Canon W-E1 Wi-Fi Adapter). But best of all, the newest Canon EOS 5D Mark IV, which was just released last month, is Canon’s first high-end, full frame DSLR to have full Wi-Fi built in. So an updated post on this subject was needed.

The Making of a DIY Brushless Gimbal With Arduino

https://www.instructables.com/id/DIY-Brushless-Gimbal-with-Arduino/

Saved by uncleflo on November 28th, 2018.

This is a story of my third project with cheap gyro and Arduino. After the earlier two projects, Easy Inverted Pendulum and 3D Calligraphy, I have thought of making Camera Gimbal with Arduino. Then I had three policies for the project: Equipped with standard camera bigger than GoPro; Simple as possible with no special device nor kit; Bootstrap: Refer to fewer websites as possible and finish with no imitation. At the start of the project, I had intention of making 2-axis gimbal with Servo Motors. But it has been made clear that it is difficult to see adequate performance using Servo Motor. Consequently a 3-axis gimbal with Brushless Motors and Arduino has been made. INTRODUCTION VIDEO below shows the effectiveness of the DIY gimbal. In the video, pretty noise would be heard suddenly. It is left without any reduction to show strengths and weaknesses of the gimbal. Arbitrary film editing is avoided.

Wind Turbine Design

https://learnengineering.org/wind-turbine-design/

Saved by uncleflo on November 28th, 2018.

Primary objective in wind turbine design is to maximize the aerodynamic efficiency, or power extracted from the wind. But this objective should be met by well satisfying mechanical strength criteria and economical aspects. In this video we will see impact of number of blades, blade shape, blade length and tower height on wind turbine design. The next big factor which is affecting performance of wind turbine is shape and orientation of blade cross section. A moving machine experiences fluid flow at a different velocity than the actual velocity. It is called as relative or apparent velocity. Apparent velocity of flow is difference between actual flow and blade velocity. Absolute velocity of the flow is shown in first figure, while apparent velocity in the second figure. It is clear that apparent velocity of flow is vectorial difference between actual and blade velocity. The vector difference is shown in the first figure at a particular cross section. A rotating blade will experience an apparent velocity of flow.

9 Cuts Every Video Editor Should Know | Filmmaking Tips

https://www.youtube.com/watch?v=Wv3Hmf2Dxlo

Saved by uncleflo on November 1st, 2018.

1) Mechanical - How is the film assembled?
a) Straight Cut: This is your basic cut. It's literally putting two clips side by side.
b) The Split Edit:
i) J-Cut: As you watch the first clip play, you begin to hear the audio from the next clip before you see its visuals.
ii) L-Cut: It's a J-cut in reverse. You're transitioning with Shot A's audio. This is used with dialogue scenes.
c) Jump Cut: Cut bits and pieces out of it, and put the fragments you want to include in your timeline back together. It'll look like the clip is "jumping" around through time.
d) Cutting on Action: To put it simply, "Cutting on Action" just means cutting in the middle of your subject's action.

2) Narrative - What does the cut say?
a) Match Cut: It matches the similar actions and content of both shots.
b) Contast Cut: Drawing a connection between two things. An example being cutting from a crown of shoppers to a herd of sheep.
c) Cross-Cutting: Also known as parallel editing, it is editing two different stories so they play side-by-side.
d) Cutaways: Also called an Insert Edit. These kinds of cuts are helpful if you want to add shots that give more information and context to a scene.
e) Montage: You know what montages are, right? The subject is all over the place and different cats, to show he did a lot of work for something specific.
f) The Transition: Any kind of mixing effect that merges clips together, like a fade or dissolve.
