CowCatcherCowCatcher is an Open Source initiative aimed at providing authoring tools and a repository for Java training material. This material is primarily directed at those who provide Java class-room training (like ourselves!), but may be of use for anyone studying Java.
Browse the Online Java Courses to get an idea of what we are developing.
CowCatcher community-members are jointly authoring Java Courses using the HolyCow! © content management framework. This framework, written in Java, allows you to author training-material in XML and generate HTML and PDF. The material allows authoring all the resources for a complete training: slides, notes, examples, exercises, quizzes, answers and background reading material.

These files are executable. jar, with names like Boleto_Cobranca, Pedido_Atualizacao orImprimir_Debitos. If we decompilamos them, we obtain code obfuscated names of variables and methods extremely long:
Beyond obfuscation, we can observe some of the imports in the image. We see that the last five imported classes have to do with encryption, using the symmetric algorithm DES. Then, if we identify the methods that perform the decryption, and perform the replacement methods and variables by most representative names, we have something like this:
The key used for decryption is equal to the name of the Java class. Therefore, somewhat adapting the maincode, it can make is malware decode all your strings for us. In fact, we can parse the main class in search of these strings and then pass this list to our modified code, carry out decryption.
We then see some of the strings encrypted and decrypted:
We have highlighted the IP address of the server that is contacted by the malware, which varies between the different samples that we have analyzed. We see, in addition, that builds a Visual Basic Script, which is then executed with the cscript.exe file.
It is worth clarifying that analyzed files have other features, which can be seen in the rest of theimports. Perhaps what is most worthwhile to mention has to do with detection of virtualized environments, thwarting her execution. We also see downloading files from the Internetfunctions, as with the rest of the imports:
It is striking the diversity in languages and platforms used in Brazil, but there was how the objectives of cybercriminals and their methods of propagation are still the same.
Sale and promotion are banned in the country. ANMAT reported the incident to the Directorate of Registration of Internet Domains.
Websites offering “electronic cigarettes” whose sales and promotion are banned in the country, were discharged after the National Administration of Medicines, Food and Medical Technology (ANMAT) -organismo under the Ministry of Health of the Nation, by Juan Manzur- carry out the corresponding complaints to the National Registry of Internet Domain Names.
As a result of these efforts, concretized through the Program Monitoring and Control of Advertising and Promotion ANMAT, the lower of the following websites are provided:
www.fumarelectronico.com.ar, www.e-cigarrillo.com.ar and www.argentinagreensmoke.com.ar.
The so-called “here are the best electronic cigarette 2016” is designed for replacing the consumption of snuff derivatives or just to simulate the act of smoking device products. So far, they have not presented scientific evidence of its efficacy and safety, or the exact chemical composition of the contents of the cartridges of these products, both those who advertise that contain nicotine as that of promoting not contain known.
For these reasons, the population should not be acquired or used such devices are recalled and can be denounced the illegal Internet sales and misleading advertising of health products.
Compressing the CSS and JS code and other files with GZIP increases the speed of the web and improves SEO
The speed of a website is a very important for local SEO services and usability factor.Google gives more importance to the rapid sites whose load does not take more than a few tenths of seconds (based on broadband connections), since their goal is always to provide the best user experience.
Loading speed to many factors such as the weight of downloads from the server (code, photos, videos, etc.), the number of calls to the server, calls to external APIs, etc. should
We can analyze each of these factors through very valid and free tools such as GT Metrix and Pingdom Tools , which give a note to the webpage you want to analyze based on all factors of WPO (Web Performance Optimization) and show detail the performance of each aspect of the web, and how to improve it .
COMPRESSION CSS and JS
One of these factors, as mentioned, is the code.Surely all who have handled some code may have noticed that contains many blanks and notes that make each .css or .js file is larger in Mb of what could be.
There are online tools that will work for us: will erase all unnecessary spaces and characters in a file or .js .css to restore a version commonly called “min” much smaller.
my favorite, lets you choose different options and the degree of compression (4 levels from very high to low)
YUI Compressor uses and can compress both CSS and JS
very simple to use.
COMPRESSION HTML and PHP
Close the HTML or PHP of a page is not as simple operation, as it is touching a very sensitive code, which can include CSS elements and Java encrusting (the <style> to give styles in HTML and <script> Java, including the same Google Analytics)Yet there are online tools to compress these codes. One of them is:
NOTE: the tool itself warns that by minimizing the HTML <pre> tags (preformatted text) and the style will be lost white-space: pre ;.
Once we have obtained the compressed versions of our codes, we will update existing links between the different files and finally upload to the server.
GZIP: CHOICE OF COMPRESSION
Gzip is another way to compress the contents of a web , and is a command that works on the server side. So it’s the server, once these instructions are sent compression, which knows which files have to be compressed.Today is a very effective and widely used solution, which can lower the size of files from a web up to 70%.
NOTE: Gzip does not compress any file type. In fact .pdf files, .jpg, .png, .mpg, etc. It is always better optimize or compress thembefore uploading them to the server (here an interesting note about http://yslow.es/compresion-gzip/ ).
Gzip, being a given server command, including active lines of code in the .htaccess file.
mod_gzip_item_include file (html |? txt | css | js | php | pl). $
mod_gzip_item_include cgi-script handler ^ $
^ he mime text mod_gzip_item_include /.*
^ he mime image mod_gzip_item_exclude /.*
mod_gzip_item_exclude rspheader ^ Content-Encoding:. * * gzip.
To work, the server will need to have the relevant library, that accepts the command mod_gzip activated.
Another option is to use the mod_deflate command:

AddOutputFilterByType DEFLATE application / vnd.ms-fontobject
AddOutputFilterByType DEFLATE application / x-font
AddOutputFilterByType DEFLATE application / x-font-opentype

Both tablets and smartphones are devices that use applications, to carry out an unlimited set of tasks. An application is a computer program that is designed to perform singular or multiple tasks. Many apps can be very useful in the dental practice. Downloading directly to the devices through the Apple Store or Google Play, depending on the operating system of your phone. Many of them are free, others are free download but require an update to payment of the annual subscription for full functionality, and some applications must be purchased. Rates can be as variable as €0.89 hundreds of euros.
Below is a list of what we believe to be the five most useful for dentists applications thanks to the consult of experts from Freedom Dental Melbourne.
