Product requirements document - Wikipedia

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

Saved by uncleflo on January 18th, 2019.

A product requirements document (PRD) is a document containing all the requirements to a certain product.
It is written to allow people to understand what a product should do. A PRD should, however, generally avoid anticipating or defining how the product will do it in order to later allow interface designers and engineers to use their expertise to provide the optimal solution to the requirements. PRDs are most frequently written for software products, but can be used for any type of product and also for services. Typically, a PRD is created from a user's point-of-view by a user/client or a company's marketing department (in the latter case it may also be called Marketing Requirements Document (MRD)). The requirements are then analysed by a (potential) maker/supplier from a more technical point of view, broken down and detailed in a Functional Specification (sometimes also called Technical Requirements Document).

An Introduction to Lean Canvas – Steve Mullen – Medium

https://medium.com/@steve_mullen/an-introduction-to-lean-canvas-5c17c469d3e0

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.

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.

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.

How can we find the tf-idf value of a word in the corpus?

https://www.researchgate.net/post/how_can_we_find_the_tf-idf_value_of_a_word_in_the_corpus

Saved by uncleflo on December 23rd, 2018.

I am working on text classification using SVM. In a paper (Fuzzy Support vector machine for multi-class text categorization) the author has reduced the features(words) by applying the following criteria: "Eliminate the words that are ICF>log2, Uni<0.2 and TF_IDF<26". My question is how can we find TF_IDF value of a word. TF is a local measure and IDF is a global measure. TF_IDF gives different value for a word in each document. TF-IDF is the acronym for Term Frequency–Inverse Document Frequency. This metric aims at estimating how important is a keyword not only in a particular document, but rather in a whole collection of documents (corpus). Actually, a lot of common words like articles or conjunctions may appear several times in a document but they are not relevant as key-concepts to be indexed or searched. TF (Term Frequency) provides a measure about how frequently a term occurs in a document.

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.

Applications for unmanned aircraft operational authorisations

Saved by uncleflo on November 27th, 2018.

The process to follow when applying to the CAA for an operational authorisation (a permission or an exemption) depends on the relative complexity of the authorisation that you are seeking: Applications for relatively ‘simple’ operational authorisations, which are commonly referred to as a ‘Standard Permission’, are addressed via an online application process: A ‘Standard Permission’ enables a person to conduct commercial operations with a small unmanned aircraft (drone) and also permits operations within a congested area. Applicants will be required to provide all documents and payment online (credit /debit card only ) before submitting their application. Applications for more complex operational authorisations, commonly referred to as ‘Non-Standard Permissions’, or those that require a specific Exemption from the Air Navigation Order are addressed via a more traditional ‘paper based’ application form, the SRG 1320.

GNU gettext utilities

https://www.gnu.org/software/gettext/manual/gettext.html#Why

Saved by uncleflo on June 29th, 2018.

Usually, programs are written and documented in English, and use English at execution time to interact with users. This is true not only of GNU software, but also of a great deal of proprietary and free software. Using a common language is quite handy for communication between developers, maintainers and users from all countries. On the other hand, most people are less comfortable with English than with their own native language, and would prefer to use their mother tongue for day to day’s work, as far as possible. Many would simply love to see their computer screen showing a lot less of English, and far more of their own language. However, to many people, this dream might appear so far fetched that they may believe it is not even worth spending time thinking about it. They have no confidence at all that the dream might ever become true. Yet some have not lost hope, and have organized themselves. The Translation Project is a formalization of this hope into a workable structure, which has a good chance to get all of us nearer the achievement of a truly multi-lingual set of programs. GNU gettext is an important step for the Translation Project, as it is an asset on which we may build many other steps. This package offers to programmers, translators and even users, a well integrated set of tools and documentation. Specifically, the GNU gettext utilities are a set of tools that provides a framework within which other free packages may produce multi-lingual messages.

Quora - What is the best JS, CSS, HTML, and PHP minifier?

https://www.quora.com/What-is-the-best-JS-CSS-HTML-and-PHP-minifier

Saved by uncleflo on June 1st, 2018.

JavaScript: I’d rate Google’s Closure Compiler as the best, and UglifyJS second. There isn’t much data out there comparing them, especially the current or recent versions of them, but Closure gets lots of attention from talented people and its minification is guided by smart optimizations. In that sense, it’s a true compiler, doing things like dead code elimination and some restructuring. CSS: CSSO and CSS Nano are both good. CSSO was created by Yandex, and I’m generally impressed with Yandex’s talent. (They’re the Google of Russia, sort of.). HTML: As far as I know, there isn’t a good HTML minifier right now. WebMarkupMin might be good, but it’s new and I haven’t tested it. The most popular is HTML Minifier, but it’s buggy, poorly documented, and unsafe – it can easily break your website, and they’re strangely unwilling to fix their bugs (see this bug). A golang minifier deletes the `<html>` and `<head>` tags, which is fascinating. For some reason HTML minifiers seem to be in the hands of people who are willing to take alarming risks with HTML – it’s a weird bubble in the universe. We could really use a focused project to build a reference HTML minifier, and I’ve asked Cloudflare to open-source theirs (but I have no idea if they will).

Count number of lines in a file using DOS

http://brett.batie.com/scripting/count-number-of-lines-in-a-file-using-dos/

Saved by uncleflo on May 29th, 2018.

Every once in a while I get on a computer and I need to count the number of lines in a file. My first instinct is to open my text editor (editplus) and hit ctrl+end to get to the bottom of the document. Then I can view the status bar which will tell me the line number. This works fine when I am on my computer but not when I am on another computer that does not have editplus installed. My next option might be to open this file in notepad and do the exact same thing. This will work fine if the file is not to large. The problem is I often deal with very large files. I need a quicker way to produce the same results. This is where DOS comes into play. I can use the following command and let DOS quickly tell me the number of lines in the file.

Operational Transformation

Saved by uncleflo on June 23rd, 2017.

Software that lets you edit a shared document together with others over the internet can be really useful if you’re working in a team, especially a distributed one. Nowadays, there is a lot of web-based software for simultaneous collaborative editing, no matter if you’re working on rich-text documents, spreadsheets, presentations or source code. Let’s take a moment to define more precisely what we mean with the term realtime collaborative editing. What we want is that multiple people working at different computers can make changes to a document hosted on a server at any time. These changes are synchronized immediately with the other peers, in contrast to version control systems like Git, where one usually works on a feature all by oneself and eventually merges the changes back to the project. No client should have to communicate with the server or any other client before making a change. In particular, there is no need to acquire a lock from the server to make an edit and concurrent edits can occur. After all changes have been synchronized, every client should see the exact same document. It turns out that implementing this kind of real-time collaboration is far from trivial. The most common solution responds to the name Operational Transformation (usually abbreviated OT). It originated from a research paper published in 1989 but got more recently popularized by Google Wave. Today, it powers many collaborative editors such as.

This page contains general information posted by the FPS Foreign Affairs. If you are residing abroad, please verify in this list whether your embassy or consulate has posted specific information for your place of residence on its website. A passport is an official, worldwide recognized and usable travel document in the format of a booklet issued by the relevant authority in a particular State to its nationals. One must make a distinction between a passport and an identity card which, as its name implies, is just a single card. Belgian passports are valid 7 years (5 years for minors). Any Belgian citizen can be issued his or her own passport starting at birth. It is possible to travel to around 50 countries using an identity card, but a passport allows its holder to travel to any country in the world, subject to fulfilling any applicable visa requirements.

Saved by uncleflo on November 17th, 2016.

Web Service Atomic Transaction is an OASIS standard. To achieve all-or-nothing property for a group of services, it defines three protocols (completion, volatile two-phase commit, and durable two-phase commit), and a set of services. These protocols and services together ensure automatic activation, registration, propagation and atomic termination of Web services. The protocols are implemented via the WS-Coordination context management framework and emulate ACID transaction properties. Following the standard, a distributed transaction has a coordinator, an initiator, and one or more participants. This document describes the WS-AtomicTransaction namespace. It also contains a directory of links to related resources using Resource Directory Description Language (RDDL) 2.0.

Saved by uncleflo on October 21st, 2016.

WSDL is an XML format for describing network services as a set of endpoints operating on messages containing either document-oriented or procedure-oriented information. The operations and messages are described abstractly, and then bound to a concrete network protocol and message format to define an endpoint. Related concrete endpoints are combined into abstract endpoints (services). WSDL is extensible to allow description of endpoints and their messages regardless of what message formats or network protocols are used to communicate, however, the only bindings described in this document describe how to use WSDL in conjunction with SOAP 1.1, HTTP GET/POST, and MIME.

SVG Basics Tutorials - Scalable Vector Graphics by Hand

http://www.svgbasics.com/

Saved by uncleflo on June 13th, 2015.

Welcome to the SVGBasics tutorials. Scalable Vector Graphics (SVG) is a standard from the W3C which is built on top of XML. The SVG standard describes ways that graphics can be drawn for use on the web. I've assembled here some examples that you can freely modify and reuse. The idea is to cover the basics with numerous examples that people can experiment with to get an idea of what SVG can do. The Scalable Vector Graphics (SVG) recommendation comes from the W3C. The recommendation describes how to create vector graphics using a mark up language. Because SVG is based on XML, tools that already know how to interpret XML will be able to interpret SVG. Having this well-established standard as a foundation saves a lot of the work in defining the language. It also means that there are numerous tools around which can check the structure of an SVG document or read it to pull out interesting information.
