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.

Saved by uncleflo on January 4th, 2019.

If a user wants to execute a command, he has to first log in into a system. But some users in the system have /bin/false or /sbin/nologin set as a default shell in the /etc/password file. If I change /bin/bash to /bin/false in case of my user, I won't be able to log in into the system, so I also won't be able to run commands. But the shellless users do it anyway: How can a user without a shell execute a command? In POSIX, every running process has three User IDs (UIDs) associated with it; the real UID, which identifies the user who launched the process, the effective UID, which is used to determine what resources the process can access, and the saved Set-User-ID (SUID), which is the effective UID the process had when it started (at the point of the last exec() call). Of these, the effective UID is the most significant, since it is the one used when determining access control decisions regarding the process.

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

https://graspingtech.com/mount-nfs-share-windows-10/

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

https://mapr.com/docs/51/DevelopmentGuide/c-mounting-nfs-on-a-windows-client.html

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).

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.

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.

Saved by uncleflo on December 23rd, 2018.

This tool provides an efficient implementation of the continuous bag-of-words and skip-gram architectures for computing vector representations of words. These representations can be subsequently used in many natural language processing applications and for further research. The word2vec tool takes a text corpus as input and produces the word vectors as output. It first constructs a vocabulary from the training text data and then learns vector representation of words. The resulting word vector file can be used as features in many natural language processing and machine learning applications. A simple way to investigate the learned representations is to find the closest words for a user-specified word. The distance tool serves that purpose. For example, if you enter 'france', distance will display the most similar words and their distances to 'france', which should look like:

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).

Saved by uncleflo on December 20th, 2018.

SpaceSniffer is a freeWare (donations are welcome) and portable tool application that lets you understand how folders and files are structured on your disks. By using a Treemap visualization layout, you have immediate perception of where big folders and files are placed on your devices. Treemap concept was invented by Prof. Ben Shneiderman, who kindly permitted the use of his concept into this tool. Start a scan process and see the overall situation. Bigger are the elements on the view, bigger are folders and files on your disk. You need more detail on a big folder? Just single click on it. The selected element will be detailed with its content. Need more and more detail? Keep selecting elements and they'll discover their secrets to you. Need a larger view of a small folder? Then double click on it, and it'll zoom to the full extent of the view. If you need to understand why no more free space is left on media, keep following bigger elements. Maybe you want to focus only on particular file types... ok. Just type the file type on the filter field (example: *.jpg) and press enter. The view will react and show you only JPEG files.
