Unicoder: New User Interface

miner, minerazzi, unicode entities, unicoder

The Unicoder Tool, available at http://www.minerazzi.com/tools/unicoder/unicoder.php now features a new user interface. This one is more user-friendly and faster.

The tool generates Unicode entities in decimal and hexadecimal notations by extracting in real time a range of unicode entities as listed at the Unicode.org site. Cached results are returned if the site is down or something goes wrong.

Who can use it?

Developers that want to test character encoded vulnerabilities; e.g., ascii/unicode injections.

Content creators that need to use specialized, international, or art-like characters or language-specific symbols.

On IR Tutorials, Google, and SEOs

cosine similarity, google, minerazzi, seos

In a Google patent article on user similarities (https://www.google.com/patents/US8458195) my old tutorial on cosine similarity is cited. If you try to follow that link, you won’t be able to access it as I removed it long ago, along with all of my IR tutorials. These changes were part of the relaunching of http://www.miislita.com as a miner.

I have seen many web pages citing that tutorial, or reproducing that one and many more from the early 2000s. Those attempts are convincing me that I should restore them, perhaps in the tutorials section of Minerazzi?

Perhaps. In the meantime, check this little one http://www.minerazzi.com/tutorials/cosine-similarity-tutorial.pdf where the connection between cosine similarity and Pearson’s Correlation Coefficient (r) is demonstrated.

Essentially, Pearson’s r is a cosine; i.e., the cosine between mean-centered paired variables. As a cosine, Pearson’s r is not additive, nor it can be arithmetically averaged, as many SEOs still wrongly think.

Miislita.com – Most Complete Puerto Rico’s Miner

We have added more records to Miislita.com miner (http://www.miislita.com), making it the most complete miner and search engine for products and services relevant to Puerto Rico.

Its News Center now features more local and world RSS News (http://www.miislita.com/prbusca), monitored with the Social Pulse Parser (SPP).

As a Minerazzi miner, this is a curated collection. So you won’t see here tons of web noise as you would get from other search engines.

For searches not relevant to Puerto Rico, please use any of the miners available at http://www.minerazzi.com

The IP-to-Country Locator is a new Minerazzi tool available at http://www.minerazzi.com/tools/ip-country/locator.php

It allows users to locate the countries that are associated to a set of IPs. Use it for data mining IPs and track down users (potential customers, spammers,….).

chemistry, fractals, minerazzi, statistics, tools

We have developed a whole new set of multidisciplinary tools for mathematics, statistics, and chemistry.

Starting today, the following are available:

Mathematics

CSS Fractal Studio – http://minerazzi.com/tools/fractals/studio.php
Create CSS-only 2-dimensional fractals and multifractals.

Statistics

Combinator – http://minerazzi.com/tools/combinator/tool.php
Compute combinations, permutations, circulations, and inversions.

Chemistry

Diluted Solutions Maker – http://minerazzi.com/tools/diluted-solutions/maker.php
This tool helps lab techs to prepare a set of diluted solutions from a stock solution.

VSEPR Wizard – http://www.minerazzi.com/tools/vsepr/wizard.php
This tool predicts central atom electron arrangements and molecular geometries using VSEPR data.

Acids Iteration Pattern – http://minerazzi.com/tools/acids/iteration-pattern.php
This tool uses an iteration pattern to compute the pH of acid solutions regardless of their dissociation strengths. A great example of Applied Numerical Dynamics Theory!

New Tools
