April 15th is known to Americans as Tax Day -- the due date for most federal individual income tax returns. Occasionally a taxpayer may need additional time to gather the information necessary to complete the return. The IRS allows a one-time automatic six-month extension to the filing date, with a final return due date of October 15th. This is only an extension of the filing date. Taxes owed must still be paid on time.
A low noise amplifier raises an input voltage to a higher output with low noise. The amp's gain represents the level to which voltage is multiplied. A basic low noise amplifier consists of these components: four outputs, four inverting inputs, four non-inverting inputs, a positive voltage input and a negative voltage input. To make power more uniform, you with also need pairs of capacitors, resistors and 9-volt batteries that share a common ground.
HP-UX core files are automatically overwritten at the next core dump. You may want to keep all of your core files for later analysis. To save a core file, rename it so that it isn't overwritten when the next core dump occurs. You can rename your core files through the terminal to prevent the loss of core file data.
The FASTA file format is a text-based format used to represent nucleotide and peptide sequences with single-letter codes. The format originated with the FASTA software package, which was developed at the University of Virginia. The FASTA format has developed into a standard in the field of bioinformatics. It is possible to download the FASTA software package and create and compare sequences on your own Mac computer.
Jvvh is among the leading updates to the operating software of FTA satellite receivers. FTA stands for the free-to-air TV market, which extends from simple antennas for local reception of television stations and signals, to FTA receivers that attach to satellite dishes capable of receiving thousands of over-the-air (OTA) signals. Coding tools for Jvvh consist of adaptations to the coding that Jvvh custom codes made to the FTA receivers. Jvvh ceased active updating in 2009.
SQLite can add powerful data-management capabilities to your website or desktop application. Unlike other data-management systems such as SQL Server, SQLite does not need servers to operate; rather, it works by reading and writing files that reside on your hard drive. SQLite does not contain many file types, but those files are critical to the system's operation.
By default, when communicating with a Lightweight Directory Access Protocol server that is using the nss_ldap module, users might experience a timeout error if the server fails to locate an appropriate resource within 30 seconds. If your server's users regularly experience timeouts, you can decrease their occurrence by editing the configuration file of your nss_ldap module.
Persistent handlers are tools that Windows' search engine uses to find files. The handlers are small extensions of the Windows Shell, registered to look for particular software objects stored on the computer. Using persistent handlers cuts down the amount of searching the Shell has to do when you ask for a search.

It memorizes any fields you type into a form, including usernames and passwords, and remembers them for future use. It also remembers a great deal of personal information, such as credit card numbers, banking information and addresses.
Archiving information on paper can take up a significant amount of space. Paper records also come with a security risk, as documents can be stolen or damaged by fire, water or property destruction. DataGrabber is a software application that supports the management of unstructured data in one or more repository. This form of data control helps to ensure the data files remain safe from loss or damage. Additionally, DataGrabber supports the archiving and distribution of file information using CDs and DVDs.
A typical software installation disc can contain hundreds of files, with each one having a vital role in the functionality of the program. Although you may click just one shortcut icon to start a program, many different files contribute to the result that you see on the screen.
GPS devices and map-related computer programs use the GPS Exchange format to record digital location-related data. Because it follows industry-standard XML specifications, a GPX file contains its own description information. The GPX standard includes support for tracks, routes and waypoints. It is an open, public-domain format available without licensing fees.
HFS files are disc images created by Macintosh computers. However, the term "HFS" can be easily confused with an early Macintosh file system, referred to as the "Hierarchical File System." HFS files, or files ending in ".hfs," are files that contain an exact replica of a CD or DVD. This allows the computer user to create a disc image using the Macintosh operating system.
The Droid line of smartphones run on Google's Android operating system. This provides each device with a standard set of features but allows manufacturers to include support for additional files and options. Although all Android devices support the basic file types for compatible applications, the APK format, any types that aren't native to the operating system may not be supported.
Samsung Epic mobile users attempting to install a DK28 update to the phone from a memory card may encounter an “eSignature Verification Failed” error message. The error message will prevent you from installing the necessary updates to your phone. Before contacting your carrier for assistance, you have several options to bypass the error.
In Debian, you can choose from different repositories to track and update packages. Lenny is the code name for the old stable repository. When a new stable version of a package is released into the stable repository, the old version moves to Lenny. If you use Totem for digital television in Debian, you can track Lenny for the package to help ensure the updates don't break the application.
Software installations and updates will often need to rename existing data on your computer. If a file is loaded into memory and currently being used, it cannot be modified. In that case, Windows schedules the file to be renamed after the computer has rebooted. These pending file renames are stored in a registry string and read during the next reboot. Identify any pending file renames by launching the Windows Registry Editor and viewing this string value.
Files in Monkey's Audio format, also known as APE, are designed to sound identical to the audio source, but may not play on many portable music players or in applications such as Apple's iTunes. Converting these files to a standard MP4 audio format may cost a bit of audio quality but offers a compatibility advantage, especially when you're on the go.
Windows users who experience a slowdown in computer functions may notice the file svchost.exe running on their computer taking up available memory and resources. The svchost.exe is a crucial component of the Windows operating system and is necessary in order to run Windows applications. However, the file uses quite a bit of memory, which in turn slows down the system. Knowledge of the svchost.exe process and what it does may help you understand which of the processes are necessary and speed up your operating system's functions.
GIMP is a graphic design program that you can use to create and edit images on your computer. It is free to download and use, providing an economical alternative to retail graphic design programs. “Unknown File Type” is the error that GIMP displays when you attempt to open a file that it can’t read. You will receive this error when you attempt to open a Script-Fu file in the GIMP program.
PPM files are a type of image file called a pixmap. PPMs allow for full RGB color and come in two types: ASCII and binary. ASCII files are designed for human-readability. They also transport well to a variety of other platforms. Binary files are easier to parse due to the lack of white space, and they are efficient at saving file space. To determine which type of PPM file you have, look at the magic number.
Comparing a Control Program for Microcomputers file to a Portable Document File is an apples-to-oranges comparison. The original CPM files came from a disk-operating program in the 1980s for 8-bit computers used to manage a computer’s hard drive. Adobe created the PDF format to allow people to share documents from most any software application in a secure format. Most files with a CPM extension are program commands, while PDF files are not.
EVI, which stands for Echoview Index, is a file format used by the hydroacoustic data processing application Echoview. An EVI file contains the index of an echosounder data file, allowing Echoview to instantly read the data stored within them. If Echoview does not read or detect EVI files, you will have to re-associate it with the EVI file extension.
The CHW file extension is assigned to a group of individual help files. CHW files are exclusively used by the Microsoft corporation, and are responsible for creating a table of contents for a user's help center articles. CHW files must stay up to date in order for the Windows Help application to be able to pull the appropriate help articles.
Files generated by the Adobe program PageMaker 6.5 are assigned the P65 file extension. PageMaker facilitates the creation of literature for professional purposes. Users are provided with a variety of pre-designed layouts and graphics, which may be combined in a range of combinations to create unique pieces for publication.
An MRK file is a computer file that carries the ".mrk" file extension. Several different file types use this file extension, and so there is no single ".mrk" file type. Each of the implementations of this ".mrk" file follows a specific format and servers a different application. These files are incompatible and they are not interchangeable.
The file extension PCB is not exclusive to one computer program. Files with extension PCB are used for at least two purposes: storing information about printed circuit boards, and the toolbars for Microsoft PowerPoint. Changing the data in either type of file can have detrimental effects on the programs with which the file is associated -- don't alter these files unless you are very savvy about their use.
A MRU file represents a file that you recently opened within a particular Windows program. This type of file does not have a unique extension applied to it, but rather has the extension assigned to it by the program that created it. For example, all MRU files in Word have the extension .doc or .docx. The list or MRU files is updated in real time as you interact with different documents.
Many different applications save data with the .pbp file extension. These include programming languages, portable PlayStation devices, video playback programs and application design utilities. PBP files can contain many different types of data, and are used only for specialty purposes. Most users won't encounter them on a day-to-day basis unless they are programmers or work with video game images.
MXF stands for Material eXchange Format and is a file used by digital audio and video media software. An MXF file is a container, or wrapper format file that describes data used by other files in a program. It specifies how different streams coexist. The Society of Motion Picture and Television Engineers defines the MXF standard.
The file extension PTX is used for several different file formats. Most commonly, a PTX file is a texture file for PaintShop Pro or a text file for E-Transcript Manager. A PTX file may also be a Pentax image file, a Punch! Professional Home Design texture file or a Participant Termination Calculation System index file.
The CDE file format is associated only with a few specialty programs. Most computer users won't encounter this kind of file on a day-to-day basis. However, users of 3D computer-aided design software may require CDE files often. This format is also associated with a type of control design software and is sometimes mistaken for several similar file formats.
The CHK file extension is used with more than one program. The files function differently in each program, and the CHK file from one program is not compatible with any other program. CHK files may be related to portions of Windows files, Blizzard video files or a specific anti-virus program.
The SAV file extension is known as a common file, because it is used by different computer applications. The SAV file most typically represents a program or video game that is partially completed. The files save information so that a user may step away from a program session and find it in the same state upon return.
Seven file types carry the description “RBF” and are identified by the RBF file extension. File extensions are not enforced by copyright. Software houses select file extensions based on abbreviations of file contents or the applications that use them. This results in the repetition of file extensions for unrelated file formats.
The file extension PLF may indicate several different uncommon file types for a wide variety of program types, including media, gaming, software licensing and sales management. A file with the PLF extension is most likely a playlist file for WinDVD. Another relatively common type of PLF file is a license file for Papyrus Live Updater.
A VCM file is a computer file with a file extension of VCM. File extensions are not unique to a file type and the VCM file extension is attached to three types of files, each used by a different application. The common usage of the same file extension for three different file types is coincidental. A file produced in one application that uses the VCM file extension will not open in another application that uses the same file extension.
Many applications developed for mobile phones make use of the Short Message Service, or SMS, to deliver data. The Android Application Interface, or API, supports the SMS and can be used to develop applications that use this technology to send and receive data. To access the Android API, you need to have the Android SDK installed and work in the Eclipse Integrated Development Environment. The ADT Eclipse plug-in is also required to allow the IDE to interface with the Android API.
In AutoCAD, you can export your work into a number of different file formats. One of these is the DXB or Drawing Interchange Binary format. This format only contains certain data from the drawing such as basic shapes and polylines, and it is often used to transfer the general concept of a drawing between two programs that are generally not compatible or to send rough outlines of drawings to plotters. DXB files can be created using a custom plotter driver.
Initiailly released in 1996, the Nintendo 64 was Nintendo's first 64-bit gaming system. Like the original Nintendo Entertainment System, Nintendo 64 games were encoded on plastic cartridges rather than the optical media used by modern video game systems. A Z64 file contains a copy of the data contained on a Nintendo 64 game cartridge.
A "Z64" file extension is a data file copied from a Nintendo 64 game cartridge. The Nintendo 64 was a classic gaming console designed and sold by Nintendo starting in 1996. Its showcase game was "Super Mario 64," which is one of the more popular Z64 emulator files that you can find online. Although the Nintendo 64 is no longer manufactured by the company, you can still download hundreds of Nintendo 64 game titles to play on your personal computer.
In the early 1980s, pioneering personal computer software maker Ashton-Tate released a program called dBase II, the first database manager for microcomputers. DBase II had its own programming language and used .dbf files containing user-definable fields for character, number and date information. By building custom .dbf files and writing programs in dBase II, software developers created custom accounting and management software applications for small to medium-sized businesses.
With the right tool kit and experience, you can create Web applications that look more like desktop computer programs than typical Web pages. Flex and ColdFusion are two programming tools produced by Adobe Systems Incorporated you can use alone or together to create Rich Internet Applications or RIA Apple Mac OS X, Windows, Linux, Unix, iOS and Android users.
MATLAB is a mathematical and statistical analysis package produced by software company MathWorks Inc. MATLAB contains a number of built-in numerical and graphical functions, and as it is essentially a programming language, it is highly customizable. If you need to draw a circle and mark a specific point in that circle, you can do so with complete accuracy using the coordinates system built into MATLAB.
Optical media has a finite shelf life, so it is important to back up discs in case your originals become scratched or otherwise unreadable. If you have a PlayStation Portable game system then you can create or download backup copies of your games in the compressed CSO file format. You can only legally obtain a CSO file for a game that you already own.
