Computer-Software-Tools

Some individuals have very specific needs in regards to file renaming. A large number of needs is often accommodated with the power of PFrank pre-defined commands, regular expressions, and specialized commands. However, every so often some one-of-a-kind, unique, or perhaps insane request may come along that cannot be solved while using the current version of PFrank and unfortunately may also be not general enough to generally be included to be a standard feature.

PFrank is straightforward but convenient solution to change and alter multiple files all at once and never have to endure them one after the other. The developer states happen to be motivated by way of the insufficient a reliable renaming program as most need to be run with multiple passes using different sets of renaming sequences before getting the required names. PFrank enables you to rename anything you need to in one fell swoop with a Windows Explorer style software interface.

When you first start PFrank, you’ll find 2 basic things you can create before you begin creating your renaming sequence. The very first is the actual Folder as well as second will be the Name Filter. The latest folder determines where your files/subfolders are going to be renamed from. You may use the browse button to choose the folder, you may enter the full path manually into the text field, or maybe the fastest way is usually to just drag the folder into your text field. Should you be brand new to PFrank then it’s strongly suggested to manufacture a test folder with copies of a few of the names you would like to change. Operate the test folder as your current folder. Then continue with the strategies outlined below to experiment on what they are called. Even if you are at ease with your renaming skills you’ll still may want to come up with a backup epidermis original names in the event that something goes wrong.

PFrank use a lots of ways for deciding how and what sort of files you should rename which may be a bit tricky. This is why, the developer initiated a policy of a forum which works with the majority of the main problems. Particularly together with the the latest features that were added, you could experience problems. These include the revolutionary plugin for insertion of meta data from raw image files (e.g. cr2, nef, sr2) and also a much improved undo facility, new filters, new positioning controls as well as the ability for users to plug in their unique renaming commands. Additionally there is a recently added custom list manager for managing numerous custom lists for repeat file changing.

Pfrank comes equipped with many features, most of which you simply won’t find on any other renaming program. The nice thing about this tool is that you can easily build any renaming command sequence you want, preview each of the results, press the rename button, and you are done!

Pricey, affecting casual users in general, is always that PFrank contains a steep learning curve when compared with other renamers. The best rename will need a little bit studying with the help file. Technically minded users may grab the syntax quickly enough to make it worth their while. Check Panda Batch File Renamer for alternative free file renaming software.

Currently, there are quite a number of different graphics file formats. Nevertheless, all of them can be divided into two groups. These are files that store vector graphics, and files stored raster graphics. Raster graphics – is a format when the image is stored in the form of small dots – pixels. Accordingly, the quality of such images is limited by two factors: it is actually the size of the image in pixels, and image resolution – that is, the number of pixels per unit length (the most common pixels per inch). Files stored in raster graphics are a jpg, gif, bmp, tiff, png, psd and others.

Vector Graphics – is a format when the image is stored as an array of numbers describing the construction of images in the form of curves and the key points of the vertices. Formats of vector graphics are swf, cdr, max, ai, partly pdf.

In practice, web graphics are mainly used in two formats, raster graphics – jpeg and gif, and a vector graphics – swf. The format png is much less frequently used.

Jpeg and gif formats differ in different image compression algorithm. Since the web file size still plays a very significant value for several reasons, therefore, light weight graphics file significantly increases the speed of loading images. For different “types” of pictures fits a particular format graphics.

Determining the required format is the basic ability of a web-designer.

The format jpeg is best for photos, portraits, large pictures rich with intricate details. Compression algorithm of this format works so that, when the “weight” lessen of a picture, and therefore the quality of the image, as if “smeared out”, becomes ill distinguish the clear transitions between colors, and stray colored pixels appear as a side effect of the algorithm. The degree of compression of a file is determined each time by the designer on the basis of its needs, but the optimum ratio of the size / quality of the image compression rate is equal to 65.

Gif format is best suited for images of small size, where transparency (alpha channel) is necessary, and for animated bitmaps. Compression algorithm of the format is based on the fact that the image is given a fixed color palette (from 2 to 256 colors), and all similar shades are discarded or replaced by the adjacent colors.

Also, the algorithm calculates the image lines from left to right, and stores the information not about each pixel but considers how many pixels of the same color are in a row, and stores the information only about the color and the number of pixels. This significantly reduces the weight of the file. It is easy to see that the vertical gradient (top-down) will weigh in this case is much smaller than the gradient of the horizontal (left to right). This should be considered when creating images, especially when you create animated banners, where the weight is composed also of the number of frames and is literally a war for each byte.

Png format is rarely used. It differs from the format of gif that png to preserve more information about the file. In particular, information about the alpha channel. In gif format each individual pixel can be either completely transparent or completely opaque. This imposes restrictions on the use of transparent transitions in transparency, because of what gif files with transparency often look “jagged” at edges. However, due to the large weight png files practically are not used. It is applied a variety of visual tricks in the format gif, in particular the addition of the “transitional” pixels at the edges of the image.

When naming files you should follow the simple rules. First, it should be avoided as meaningless and “speaking” names. The file name should immediately determine its place in the web page. That is, if it’s an image to the article, it should be placed in the folder articles and its name is the id of the article. If this is the position in the directory, then in the appropriate folder (items, groups) the picture must have the name ID of the group, subgroup or product.

At the same time, if, for example, the site is very rarely write articles, you cannot add additional folders, but then the file must be on the name is uniquely associated with this section. This can be done for example by adding words to the news or art picture id (such as news-34.jpeg). If a few pictures of different sizes refer to one id it is needed to add an extension after the picture id, indicating the size (for large images – b, for small – s) (Example 38-s.gif, art-2008-b.jpeg). For several images of the same size, you can enter the serial numbers (example: art08-b_01.gif).

When naming pictures that form the design of the website, you should use the following notation: top – for the header of the site, bottom – for basement of the site, but – for various kinds of buttons, ico – for the icons, img, or pic – for other images of registration with the addition of numbers in end.

The main programs for working with images from the designer are Adobe Photoshop and Adobe ImageReady for raster graphics; Corel draw and Macromedia Flash for vector. It is also used sometimes for vector graphics software Adobe illustrator – but it’s a matter of designer’s taste, because the programs are essentially identical and have similar functionality.

With the term “bitrate” we face at the mention of audio and video formats. To understand this term, you must master the process of compressing and encoding files. German scientists have laid the general principle of file compression with minimal loss. On the example of coding the original MP3 sound file is cut into fragments, the duration of 50 milliseconds, each of which is analyzed separately. In the analysis of the fragment is decomposed into harmonics of the Fourier method, of which, in accordance with the theory of sound perception by the human ear thrown those harmonics that people perceive worse than the rest. These are quieter harmonics on the back of the higher ones. As a result, emitted sounds are masked due to the inertia of hearing. The information about the harmonics left after filtering and recorded in the MP3 file, which results in a much smaller than the original WAV.

WAV-file contains detailed information about the original sound, digitized and quantized with a frequency of 44kHz. This information is stored on ordinary audio-CD. When playing there is the inverse transformation, in which the remaining harmonic is re-converted into sound waves. Some of the information about the original signal was lost, because the sound is not identical to the original. But throwing irrelevant sounds, so the human ear cannot distinguish the signal from the original order, which was packed to MP3.

Bitrate is the amount of information per unit time. Its essence – how much information about every second of recording we can spend. Naturally, as it is smaller, the smaller the size of the files have the same length of time, thus will have to throw more “extra” harmonics. Bitrates are units of measurement – kilobits per second (Kbps) and megabits per second (Mbps). MP3 audio compression algorithm is often used with 128 kbps compression. They are of two types: fixed and variable. For example, when a video compression is used with a constant bitrate a fixed amount of data is used to encode a second film. In the case of variable bitrate the codec installs eigenvalue bitrate depending on the scenes of the movie. For example, when encoding to mpeg the gain in compression is mostly obtained by retaining only the difference between adjacent frames. During a slow scene change the difference between frames is small and thus can reduce the amount of a bit rate required for playback of these scenes. However, with the abrupt change of scenes in the film, the differences in staffing increase dramatically in size and require more bitrate to play such scenes. In contrast to the constant bit rate, at a variable one cannot predict the size of the output file, it depends on the ratio of “fast” and “slow” scenes in the film.

Regarding to radio online, the downloadable sound quality of radio stations with the network also can be analyzed by bitrate. The choice between 48kbps and 128 kbps bit rate, I hope, will introduce you to a long meditation.

The successfully passed operation of recording digital audio on the CDA (Compact Disc Audio) announced to the world about the beginning of a new era in sound recording. In 1982 in Langenhagen, near Hanover, was discovered the mass production of CDs. The rapid development of computer technology and digital technology, which began a little later, led to the necessity of compression of digital audio. The reason for this was a mass. Saving disk space, increasing the speed of transmission of digital information, the need for a sound recording format, suitable for use in the software.

In 1987, the German Fraunhofer Institute (Fraunhofer Institut für Integrierte Schaltungen) has launched a comprehensive study of the problem of encoding digital audio. This institution owns the patent on the technology MP3. Karl-Heinz Brandenburg is the “father” of the sound format, mathematician and electronics, who studied the methods of compression since 1977. In 1989, when he was received a patent on the format, a single MP3 file did not exist. In 1993, the MP3-files have been found to comply with the international standard MPEG-1.

What principles were the basis of encoding digital audio in this format?

Original audio file is divided into frames the duration of each is 0.05 seconds. Then analyzes of each frame appeared. In this case, all the sound frequencies that lie outside the range of perception of human ear are discarded. In addition, oscillations that are too high or low value of amplitude are discarded. As is known, its upper limit of human perception is of 96 dB. The lower boundary of perception depends strongly on the frequency of the sound. High and low frequencies have a higher amplitude threshold of perception. In the first phase signal of each frame, the mathematical Fourier transform as a sum of sinusoids of various amplitudes and frequencies (in fact graphically sound at any frequency is just a sine wave). In memory of recorded amplitudes and frequencies contained in the resulting formula. The second stage of processing is based on a psychoacoustic model of human perception of sound ear. For example, discarded small incremental changes in sound frequency (the signal frequency of 5000 Hz followed by a 5100 Hz signal is recorded as one with a frequency of 5000 Hz and summed duration). Another feature of the ear leads to the effect of frequency masking. Sound with a certain frequency masks other sounds with similar frequency but smaller amplitude, which is discarded. The inertia of the ear perception of sound leads to the fact that, sometime after a loud pop sound of high frequency and low amplitude is simply not heard. These sounds are also discarded by filter. The third stage is the compression of the processed signal by known mathematical methods. Data compression to MP3 is carried out on a somewhat modified version of Huffman, applying when creating an archive file in PKZIP, LHA, ZOO, ARJ. As a result of all three transformations, the information contained in the original audio file is squeezed a few times. Compression ratio in the current coder is measured in kilobits per second (kbps), and can be specified by the user. In this case, he should remember that an infinite desire to decrease the file size with increasing degree of compression leads to that the second stage of processing the sound (it is settled without any restrictions) is becoming more aggressive.

There is no single opinion on the minimum degree of audio compression admissible when it is processed. Some say that 128 kbps (compression ratio – about 10:1) is quite enough, while others prefer a value twice as large. Today, most players and encoders set the upper limit – 320 kbps, which can satisfy any expert.

Your PC can get into serious problems if you do not pay attention to the regular update of the drivers. And this is where driver updater can save you much time.

Every hotel proprietor should always think of the approaches to increase quality of services and attract clients. There is a lots of competition in this marketplace. When people organize vacations these people select among many hundreds of motels. A handful of options are expensive but offer you good quality solutions while others tend to be affordable and so well suited for travelers with limited budget. Anyhow, chief executives in the motel should imagine the strategies to improve income. Much more customers mean more money. Nevertheless, clients pays provided that these are rendered excellent solutions.

As any organization, motel needs to have mission and values. It is extremely challenging to grow into success modern company without tactics. In short, the motel owners should become aware of exactly where they go. To be able to style future plans, it’s important to bear in mind of unique circumstances. This is where performance evaluation tools are employed. BSC system could very well be one of several hottest effectiveness evaluation instruments. Moreover, BSC system perfectly fits requirements of the motel company. On this page we’re going to prioritize on development of the inn BSC, along with useful information on design of reliable key performance indicators.

Above all it ought to be mentioned that discussion of strategic objectives is vital. Hotel chief executives and owners, and personnel must be aware of what they already want to undertake to be successful. Strategic objectives and mission tend to be the necessary component of any Balanced Scorecard, just like the inn Balanced Scorecard.

Design of key performance indicators is another important phase of BSC development in the motel. performance indicators ought to calculate all facets of successful managing of the hotel. Thus, for instance it would be reasonable to measure such performance measures as apartment occupancy or even revenue for each room. These performance indicators will give you many details on exactly what should be enhanced to boost revenue and reduce losses.

Inn employees ought to really recognize the interpretation of just about all crucial performance indications so that you can understand their functions in strategy implementation. One of the leading mistakes in BSC system implementation is participation of top managers although not ordinary workers. If a reception woman won’t know very well what she actually should do to improve results, Balanced Scorecard will most certainly fall short.

Actually, design of efficient key performance indicators is of the most significant stages in creation of the hotel balanced scorecard. A few executives attempt to utilize experience obtained by other motels. This really is a fully wrong strategy because each and every scorecard is actually produced in the specific method. All at once all of us recommend choosing performance indicators obtained from reliable companies. Should you be curious about inn measurements go to our web site that you will discover the best deals on key performance indicators, in addition to useful content articles on overall performance assessment as well as Balanced Scorecard as a general rule.

Probably everybody has noticed that when connecting to the Internet via dial-up-modem the connection speed gradually decreases. The fact is that when connecting new users to the server provider’s connection speed is reduced (more so if the server provider “thinks” that your modem shows no activity). To restore the connection speed you can use the so-called ping.

What is a ping?

A ping (English acronym for Packet InterNet Groper) is a program used to check the availability of the destination network by sending him a special signal (ICMP echo request) and wait for a response. Pinging is a diagnostic scan of the remote object.

– ICMP (English abbreviation for Internet Control Message Protocol) – one of four protocols of internetworking level family TCP / IP, it restores the connection in bad situations in the transfer of custom packages.

Ping can be used for full-time operating system utilities. But first you need to know IP-address of the server.

How to know IP-address of the server?

a) Windows Vista: – connect to the internet

- click Start -> Connection

- in the window “Connect to a network” right-click your connection

- from the context menu, select “Status”

- in the window “Status” tab “Details”

- in the column “Property” locate IPv4-address of the server

- in the column “Value” find the address (eg, 100.100.100.100).

b) Windows XP: – connect to the Internet

- click the network status (“monitors” in the system tray near the clock)

- in the window “Status” tab “Data”

- in the column “Property” Find IP-address of the server

- in the column “Value” find the address (eg, 100.100.100.100).

To create a shortcut to ping the server provider (listed step by step process for Windows XP, Windows Vista for the differences are minor):

- right-click on the free surface from the icons on the desktop

- from the context menu select New -> Shortcut

- in the window “Create Shortcut”, click “Browse …”

– in the window “Browse For Folder” click Computer -> drive C: (or D:, if the operating system is installed on drive D:) -> Windows -> system32 -> ping. exe -> OK (after these manipulations in the text box “Type the location of the object” will address C: WINDOWSsystem32ping.exe) -> Next

- in the next window, enter the tag mark name (the default value ping.exe, but you can change this name on the other) -> Finish

- shortcut to the newly created ping.exe appears on the desktop;

- click the right mouse button from the shortcut menu, select “Properties”

- in the window Properties: ping.exe “tab” Shortcut click in the text box “Object” after C: WINDOWSsystem32ping.exe, make one space and enter the IP-address of the server, which was found previously (eg, 100.100.100.100), then click OK.

Now, when you notice that the speed of your Internet connection drops periodically ping the server provider by clicking on the shortcut.

Notes: 1. Answers of the ping server such as “timed out a request” or “The specified node is unavailable” usually indicates a problem of the server provider.

2. Firewall server can be configured to block requests and responses; it results in the normal functioning of all network services. In this case a ping does not make sense.

3. Ping can be any node in the network, both local and global. For example, you can ping any site to find out its IP-address, it needs to use the ping utility with the-a (prefix http:// it is not necessary to paste into the command).

Your computer can get into serious problems if you do not pay attention to the regular update of the drivers. And this is where driver updater can save you much time and efforts.

What is User Account Control?

UAC protects, requesting permission or an administrator password before making a potentially dangerous activity or a change in the parameters that can influence on the work of other users. Appeared UAC-post should be read carefully to check whether the name of the action (program) that which actually produced (runs). Check out these steps before you start, UAC can help prevent the installation of malicious software and spyware, as well as the attempts of these programs to make unauthorized changes to the OS. If the job is complete to allow or require a password, UAC displays a warning in the form of one of the following messages:

- Windows needs your permission to continue (the function or program of Windows, which can affect other users of this PC, you want your permission to run. Check the name of action to make sure that this is the function or program you want to start)

- The program requires a permit for continuation of the work (the program is not a part of Windows, permission is required to run. It has a valid digital signature that contains the name and publisher, which allows verifying the authenticity of the program. Make sure that this is the program you want to run)

- An unidentified program wants to access to this computer (an unidentified program is a program that does not have a valid digital signature from a Publisher that you can verify the authenticity of the program. This does not necessarily mean danger, because many older programs are no legal signature. However, you must pay extra attention to the program and allow it to run only if it is obtained from a reliable source, such as the original CD or a Web site publisher);

- The program has been blocked (a program that is run on this computer specifically blocked by the administrator. To run it, you should contact the administrator and ask them to unblock the program.

Why do I have to disable UAC?

UAC has a very serious disadvantage – an annoying “molestation.” User Account Control “works” in the following way- “user” is sleeping, and Vista is «on the lookout! – For any reason and does not work in peace, so experienced users prefer to disable UAC.

How to Disable UAC?

– Enter the administrator password when prompted

- uncheck Use User Account Control (UAC) to help protect your computer – > OK;

- after rebooting the PC UAC will be disabled. Disable UAC by using the system configuration Sign in as an administrator

- click logo key Windows + R;

- in the Run window in the Open box, type msconfig -> OK;

- in the System Configuration window, click the Tools tab

- in a scrolling list find facility name Disable User Account Control (UAC) -> Run

- after rebooting the PC UAC will be disabled. Disable UAC using the Registry Editor Click Start

- in the Start Search box, type regedit; -

under the heading Programs, right-click regedit.exe;

- from the context menu, select Run As Administrator

- Type the administrator password when prompted;

- a window that opens the Registry Editor, find the section [HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionPoliciesSystem];

- Find REG_DWORD-parameter EnableLUA;

- set the value to 0. Disable UAC using Command Processor Windows, click Start

– in the Start Search box, type cmd;

- under the heading Programs, right-click cmd.exe;

- from the context menu, select Run As Administrator

- Type the administrator password when prompted – after the prompt enter the command REG ADD HKLMSOFTWAREMicrosoftWindowsCurrentVersionPoliciesSystem / v EnableLUA / t REG_DWORD / d 0 / f

- press Enter.

If you’re tired of converting your videos for playback on your phone then RockPlayer is a must-have application . Maybe a battery and SD card upgrade are in order.

Analog signal using an ADC (analog-digital converter) is divided into small plots of duration of a few one hundred thousandth of a second. On each of these areas the ADC the amplitude of the sound is measured. The reciprocal of the length of these sections is called sampling rate, measured as the sound frequency, in hertz. Obviously, the higher it is (the more often we measure the amplitude), the more complete information about the signal we can save. However too frequent measurements require a lot of space to store the received information. On the other hand, reducing the sampling rate leads to a loss of information contained in the signal.

How to choose the optimal sampling frequency? The answer gives the famous theorem of Kotelnikov, according to which the sound with a frequency f cannot be digitized at the sampling rate lower than 2f. This means, for example, that an attempt to capture the sound frequency of 1000 Hz at the sampling frequency of 1000 Hz is doomed to failure. The result will be silence, or the sound is distorted, having nothing in common with the original. An important consequence of this theorem is to establish a sufficient upper limit value of the sampling frequency. Sounds of a frequency of 20 and 100 Hz, digitized with a sampling frequency of 400 Hz are generally accepted upper limit of frequency of the sound perceived by our ear, it is equal to 20 000 Hz. Therefore, the upper limit of an adequate sampling frequency sound can be taken as 40,000 Hz. In reality, the sampling frequency for audio recording on CD is 44 100 Hz. Professional studio equipment is designed to work with audio sampling rate of 48 000 Hz. The standard sampling rate for telephone lines is adopted for the 8000 Hz. This is quite enough to keep the information contained in the voice message, and also to keep an emotional and provide visibility to vote. The story does not end with the discretization.

Breaking the sound signal into the sections of a certain length and measuring the amplitude of vibration at these sites, do not forget that the value of this amplitude when recording in the computer memory also may only have well-defined discrete values. This suggests that the number of steps between the maximum and minimum values of the amplitude is limited. The number of steps depends on their height (the difference between adjacent values of the amplitude) and, therefore, than the bigger their quantity, the better the sound quality. The features of storing information in memory are led to a number of possible steps 256, 65536, 16,777,216 and 4,294,967,296 shares. These figures correspond to the 8 -, 16 -, 24 – and 32-bit sound (corresponding to the power of two, as the computer works with a binary code). Of course, the increasing of the “bit mode” of sound leads to an increase in the amount of information. However, the 16-bit audio (65536 options sound amplitude) is usually enough for most of the writing quality audio signals.
