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.

Depending on which way and what made the wheels, are very different their technical characteristics, appearance and price. Phones recognizes the significance of this. Punching steel wheels Steel is the least expensive construction material. Therefore, steel wheels until the mid-twentieth-century monopoly ruled the roads, and even now on the annual volume of issuance in the world by a wide margin, they firmly hold the leading position. Components of the wheel – the rim and CD – vyshtampovyvayutsya of steel sheet, roll and welded to each other. Steel does not have the corrosion resistance, for this reason that the wheels are made out of it, cover the primer, enamel and varnish. The main advantages of these wheels are traditionally low price and a sufficient ductility of the material, allowing the wheel during the impact is not burst, and deformed. The latter circumstance – a very important argument in favor of security, because the wheel is not completely destroyed, while maintaining some semblance of its geometry, and there is a possibility no depressurization bus. For this reason, steel wheels after injury may subject to flattening (recovery).

Of the shortcomings of forged wheels usually are their high weight, due to the required thickness, the lack of geometric precision manufacturing, poor corrosion stability and not too diverse design. Cast alloy wheels are not satisfied with the construction characteristics of steel, engineers began to look for lighter-weight materials. Thus, in the sixties were first fabricated aluminum alloy wheels. And in the future are still used, and magnesium (other metals are not taken root.) In dealing with these materials, it became expedient to make the wheel casting. The most common gravity method – casting under low pressure, with back pressure.

Spring is one of the simplest elements of the mechanism designed for the accumulation of energy. Under the influence of some of the spring changes its original form, and after unloading returns to the basic state. In operating mode, the spring may be subjected to compressive strain, tension, torsion and bending, making the springs is a specialized process that consists of several industrial and technological stages: calculation of the springs, the design of springs, spring winding (the formation of a twisted form) and hardening springs. Procedures such as replacing the springs and the springs of sale production process are not included. At the stage of the calculation of the springs is determined by its basic performance, ability to withstand the specified load. The operating mode is characterized by spring dynamic parameters such as speed and load cycles. The main tasks consist in the industry to raise the efficiency of production, its technical level and improve product quality in order to more fully ensure that all sectors of the economy with more advanced means of production – high-performance machines, equipment and devices, high-quality raw materials, and the population – those goods in wide range. Spring – part of a machine or mechanism that serves for the temporary storage of energy due to elastic deformation under the influence of the load. Cell Phones can aid you in your search for knowledge.

Upon termination of the spring gives the stored energy and recovers its original shape. The springs are widely used in railway transportation, automotive, mechanical engineering, instrument and other industries. The springs are used in As the engine of the clock mechanism. Energy use in spring lever bolt firearms. From the quality of manufactured springs depends on the reliability and stability of the arrangements.

One of the main parameters springs are its hardness, which is the ratio of compression work to the boom. The procedure is done manually winding a spring using a specially adapted to this lathe or specialized machines for spring coiling. The basic material for the manufacture of springs is steel. In cold coiling to make extension springs and compression springs used carbon steel spring wire (GOST 9389-75). The level of material quality is characterized by the values of ultimate tensile strength, proportional limit stress and elongation.

And here to help may come mediator, ie, person (or organization) who (th) takes the responsibility to introduce you to a man or woman, with all your psychological characteristics, needs and wishes. Everyone today knows that such marriage agency, dating service or dating. But how relevant and in demand in today's Internet technologies are the mediators and these services? Many people ask themselves the question: Is really to find a wife or get married, please contact the club or a dating service? The tradition came to get acquainted through a matchmaker in Russia and in other cultures since ancient times. To marry without the help of a matchmaker even thought it improper. People were care about someone they trust their own destiny, who will continue their race and become a father or mother of children. No one loves the father did not give his daughter to marry without obtaining a positive recommendation on the future of her husband. The matchmaker should have been able to find a suitable partner husband or wife, especially on social principle, and on the basis of material well-being of men and women. It was she who helped merge childbirth, to increase capital and saved them from bankruptcy due to a successful marriage.

Today, virtually the same deal with marriage agency or dating service. The main advantages of this service is a wide selection of men and women, thus chance of finding a husband or wife, and also meet for a romantic or a serious relationship communication, friendship, romance or through an agency far more. Also, a targeted search, which is an intermediary holding the information about candidates and their husbands his wife, saving you time, reduces the risk of failure, be disappointed. So, if you: – want to get married – think of yourself as successful, but in your life there is no romance and love, and you are alone at home, a lot of time spend on the job, and it is not searching for dating – love and want to meet a family – looking for a dating service for light romance and do not know where to find them – passionate about the work, and you want to flirt and recreation – like escape from loneliness and to get acquainted with my boyfriend – do not want to wind down careers and are willing to trust professionals to search, you should use the dating service to find the right person, men or Women! Dating Romantic City url: – a new dating service for marriage, love, romance and marriage! Alina Solntseva

The reason the same negative experiences become lovers, basically, purely human, social problems, "arising in the way 'lovers. Of course, many may be 'taken in arms' assertion that the natural love is merely the result of synthesis in the body of a specific chemical compound that stimulates fast convergence of individuals of the opposite sex for procreation. Of course, you must also suppress personal immunity and instinctive xenophobia. But the direct links to specific discoveries in biochemistry and physiology made in research laboratories in different countries, as this article was not on the biochemistry and psychology, and by gamologii. If desired, formulas and other technical details can be found in publications relevant professionals.

Gamologiya simply summarized the results of studies of related disciplines, viewing them in terms of achieve family happiness – true human terms. And gamologiya not appealing to religious or public morals, does not call for belief in its truth, no pressure on the sense of duty and responsibility, and simply reveals causal relationships, helping people make informed free choice, which is possible only in the knowledge of the meaning of marriage and their own purpose in life. And the fact that researchers in the sciences, at the junction which gamologiya develops, we did not do general conclusions, is due only to their specialization and their lack of knowledge gamologicheskih, but this does not detract from their professionalism and contribution to science. However, having prevalent in most modern outlook in matters of love, family and happiness, they hardly have aspired to such a generalization.

USB flash drive is a means of storing information based on NAND technology. Unlike floppy disks, such devices portable and recordable, as well as USB flash drives are much smaller than a floppy disk (2.5 to 6 cm) and weighing about 60 grams. Capacity USB drives from 64 MB to 64 GB. Some of these devices allow you to overwrite a million times and can store information of up to 10 years. Typically, USB flash drive connected to a computer with a USB connector, 1.1 or 2.0. In USB drives have the advantage over other portable storage media, particularly floppy disks. USB more compact, fast, and can carry more information, more reliable and strong. In addition, most computers are now available without a floppy drive.

Ports for USB, On the other hand, there are now almost any computer. Flash '>'> flash drive consists of a chip protected with plastic or rubber housing, so strong that it can carry in a pocket or a keychain. USB connector is usually protected by a cap. In order to begin work with a USB device must be connected to the USB port.

What is hair? Hair extensions – a novelty that the beauty industry in our market, there are about 10 years or slightly more, but none the less of her many already know, and many have tried. I would like to hear their responses. Of course, women always want to be different, new, unrecognizable. And that can most quickly change its image as a no hair, and even more so after the long hair short haircut. Change a woman loved and always amazed at men yet in the past century, using wigs and hairpieces.

Fashion hair came from Africa. African tired of their curly hair, and they wanted to be like evropeek. To do this, braided pigtails, stacked them around the head and upper sewn straight hair. Then the fashion came to America and Europe. Were developed various techniques for lengthening hair. This service is being done in various beauty salons, individual craftsmen.

Of course, technology changed considerably, but the essence of all boils down to: our hair strands are attached by 20-40 hairs about 1 cm from the head, or rather from the root hair. There are many different technologies, which are mostly can be divided into "cold" and "hot." The difference between "cold" and "hot" technology of hair extensions. The main difference between "cold" building on "hot" that in the first case, heat-treated hair is not exposed, and only mechanical, but in the second case they are attached to our hair with heated resin (small droplets) the special tool.

To date, almost every gardener is aware of the existence of a superior technology, such as tillers. However, the hoes will still have to work, especially in the beds, because the rotary cutter can easily damage the roots or foliage plants. Surprisingly, this problem was solved developers. Now assortment of special devices for inter-row tillage, they are called elektrotyapkami. On the principle of operation they are cultivators, but tasks are about the same. As for appearance, hoe is very similar to the trimmer – the same long bar with a tool from the bottom and the handle to the engine. The principle of loosening in elektrotyapok not like a motor cultivators, there is no rotary cutters, instead they are special pins carrying out the vibrational motion.

Thus, with the help of special mechanisms rotation of the motor is converted into vibration pins. Such a scheme of work has many advantages. For example, if during the work hurt his leg, there would only be a few scratches, but the threat of serious injury is low. On the other hand, the land is not turned by loosening and, therefore, remains a fertile layer. And, finally, elektrotyapki not move forward, like a tiller (due to rotation cutter), so we can handle even small plots of land between the plants. Of course, not without drawbacks elektrotyapki. For example, the productivity of their significantly lower than that of motor cultivators.

However, this tool is still very much facilitates the work of the gardener. The more so that absolutely no need to bend, because the length of the handle and adjustable, you can work straight back. In short, you can elektrotyapku certainly be viewed as an innovation in garden tools. It is worth noting that the availability of outlets for the use of such apparatus is not necessary. Some models are equipped with special batteries that can operate without charge for quite a long time.

Today's drivers, perhaps, it is difficult to imagine a model of a car without glasses. Meanwhile, exactly as were the first car. Cars the late nineteenth century to form little different from the open horse-drawn carriages carts. However, the rate of 'iron horses' speed was higher than their living counterparts, and therefore it was necessary to protect the occupant from the air stream. So in the car appeared windshield. The first auto-glass produced from the same material as regular windows. Of course, this glass was very fragile and broke into pieces upon impact, which posed a considerable danger to the occupants of people. Several later began to use tempered glass, but it is broken up upon impact.

Shatterproof Automotive solution was found in the 20e's, when construction vehicles used the new invention of the French scientist, created a three-layered glass, consisting of two layers of glass and a layer of film between them. The essence of the invention was that the three-layer glass, laminated glass, or, at impact is not divided into fragments, and remained on the film. Installation auto glass, made using the new technology has made travel by car is much safer, as shards of glass are not traumatized passengers. In addition, the installation of a windshield of laminated glass has contributed the fact that the replacement windshield was performed less frequently. Now you do not have to change all the glass due to minor cracks. Another material for the production of auto-glass – Stalin – is also a product of French scientists. It was invented in 1929 and has since been widely used in automotive.

Stalin – it has often hardened, solid glass. Feature it is that if the force of impact is very high and the glass of stalinite is broken, it shatters into small pieces with blunt edges that do not hurt people. Today, for the manufacture of auto-glass is used as a triplex, and Stalin. Production technologies continue to evolve. In particular, are spreading atermalnye glass that trap heat of sunlight, allowing the passenger compartment is not heated. Developed a variety of coatings that reduce pollution glasses. Applied electric heating of glass. Create a glass with high sound insulation. Future plans include the creation of super-strong glass that can withstand even the most severe blows.
