Each inode is identified by an integer, unique within the system files and directories contained a list of pairs consisting of a number of inode and name identification that allows access to that file, every file has one inode, but may have more than one name in different or even in the same directory to facilitate location. “In our case, our file inode is 512 495, this is the ID of our file on the system. When you delete a file with the rm command, what we do is delete the reference to the inode in question, for a time that inode will continue to exist in our system but we can not see and it appears that the deleted file has disappeared from our system. If any program is accessing the file that we deleted, are lucky. The program in question will have a reference to the inode of the deleted file and provided they do not close this program we can retrieve the contents of this file.
(A practical case that many of us ever happened to the log file to delete any system service (apache, postgresql, mysql. etc) while the service is working) Here is a full session since we delete a file until you recover: We open our file example with less (for example) less fichero_pruebas.txt THIS IS A TEST FILE TEXT fichero_pruebas.txt (END) Press Ctrl + z to suspend the less program without stopping it (the program remain open, accessing our database, but suspended) less fichero_pruebas.txt 1 + Stopped less fichero_pruebas.txt We found that our file is intact: ls-li fichero_pruebas.txt 512 495-rw-r – r – 1 root root 39 02/04/2008 22:28 fichero_pruebas.txt We erase … 😉 accidentally rm test.txt ficheros_de We found that not exist in our directory ls ls-li fichero_pruebas.txt: fichero_pruebas.txt: No such file or directory As discussed above, if we have a program accessing the file we’re lucky. Use lsof to see if any program is accessing the file that we deleted: lsof grep user fichero_pruebas.txt less 4r REG 28 410 3.1 39 512 495 / home / user / fichero_pruebas.txt (deleted) should not be a surprise that our less this program accessing our file deletion. The columns we are interested in this line are the first (PID of the program accessing the file, 28 410), and the fourth, the ‘file descriptor’ (4r) with reference to our file inode (512 495). With this information we go to the virtual filesystem / proc information on our linux system.
ls-l / proc/28410/fd/4 lr-x —— 1 user user 64 02/04/2008 22:38 / proc/28410/fd/4 – / home / user / fichero_pruebas.txt ( deleted) As expected, a reference to the deleted file. All you have to do now is copy the data to which / proc/28410/fd/4 this reference. For this we can easily use cp cp / proc/28410/fd/4 fichero_pruebas.txt.restaurado Now no matter what our program has finished running less because our already deleted file recovered. cat fichero_pruebas.txt.restaurado THIS IS A TEST FILE TEXT This article must have a little luck to keep our database, but in future articles we will see other techniques to use when luck is not on our side. That’s it for today, enjoy it.
Pablo Freire
Moreover, I recognize the imperious necessity of if reviewing the concepts that if have on the Mathematics, that is so important in the life of the man. As well as of the methods and techniques used in its education. Regarding this if it places Pablo Freire (1998, P. 26-29): I do not fear to say that reality in education inexists where a learning does not result where the apprentice if did not become capable to recriar or to remake the taught one. … in the conditions of true learnings the educandos ones go if transforming into real citizens of construction and of the reconstruction of knowing taught …. It is thus perceived, that it is part of the teaching task not only to teach contents, but also to teach to think certain.
The biggest importance of this study is the contribution that will give for all the professionals in general, that they work in the education of the Mathematics, therefore promotes a study dialtico enters the main points of the theories partner-interacionistas correlated to the educational ideas on the paper of the school and the importance of the use of the technology in classroom offering to them chances to reflect on its paper as mediator in the process of teach-learning in this area, inside of ours world contemporary. 2 METHODOLOGY The methodology of used research was of qualitative matrix, translating and expressing the direction of the phenomena found throughout the work. This type of research has inductive approach and one descriptive character of the studied given phenomena and/or where it has an interactive and direct contact of the researcher with the study object. As procedure of collection of data a bibliographical research was carried through sidewalk in books, magazines and too much publications of studious pedagogos and that if had dedicated the research educational and had launched important theories on the Mathematical Education.
Managing Barcode
It's important to remember for yourself what the product code (part number, a unique identifier) and a barcode – a completely different concept, and, in general, no relation to each other have not. Understanding this difference is easy to explain why one item (item) can have several different bar codes – any additional information that the provider sees fit to provide (color, batch number, weight, price, etc.), it encodes using the black and white stripes and puts the goods and / or packaging. How, then, when reading the scanner, the user system understands that a number of different bar codes mean the same heading? This should take care who fills the system database. Usually, it is hard to do. For example, this could look like card product for the Nokia 3720 in the program 1C: Managing commercial enterprise (on the left bar codes – how they look on the box and labels to the right – product information to the operator's screen): The image makes it clear that Nokia phones 3720, with which the organization is concerned: there is a part number 6438158055094, designated by the manufacturer to identify all the phones of this model, individual instances of different color and a unique number IMEI.
This fact denote the two sets of numbers: the code assigned 2000090001398 gray phone with IMEI 355441034567385, 2000090001404 assigned code yellow with IMEI 355241034545385. To the knowledge of the peculiarities of the goods have been available outside of the computer and database, these sets of numbers printed directly on a product (or packaging). And print it as a barcode, so you can all read it fast scanner. As a result, for one specific phone have a barcode indicating the model, and barcode with his characteristics – EMEI and color. To complete the picture, you can add a third bar code with information about the package (container) and the fourth – with transport marks.
