  • debug (11)

    When one of the early computers stopped working, it felt like the program was wrong. The fact was that a bug was crowling inside and generating electrical problems.

The word de-bug means removing the bugs from the software program.

  • decimal (4)

    Most Database systems offer a number type called DECIMAL. In general, it represents a fixed integer number with a set number of digits on the left side of the decimal point and a set of digits after the decimal point.

  • dump (6)

    The dump command, under a Unix system, is used to dump the entire file system to another device. By default, the dump output device is a tape device (/dev/tape). Now a day, however, it is often used with other devices such as another file system (from one hard drive to another.)

    Other systems use that same keyword. It is particularly the case of database systems. For instance, the PostgreSQL database has a pg_dump command.

    The opposite command is restore. That command is used to get the data from the output device and put it back on your hard drive.

  • duplicate (4)
  • DVD (1)
  • .dylib (1)
    Dynamic Library--the Mac OS/X naming convention for dynamic libraries. Not too sure why they choose that extension since FreeBSD uses .so just like most other Unices... To confuse people, maybe?

  • FAT
    The FAT (File Allocation Table) file system has its origins in the late 1970s and early 1980s and was the file system supported by the Microsoft MS-DOS operating system. It was originally developed as a simple file system suitable for floppy disk drives less than 500K in size. Over time it has been enhanced to support larger and larger media. Currently there are three FAT file system types: FAT12, FAT16 and FAT32. The basic difference in these FAT sub types, and the reason for the names, is the size, in bits, of the entries in the actual FAT structure on the disk. There are 12 bits in a FAT12 FAT entry, 16 bits in a FAT16 FAT entry and 32 bits in a FAT32 FAT entry.
  • favicon (2)

    Favorite Icon was first created by Microsoft. Like many other website features, Internet Explorer expects their favicon.ico file in the root of your website. FireFox and other browsers properly support the link tag named shortcut icon.

  • Fiesty (2)

    Name of a Walt Disney character used for a version of Ubuntu.

  • FIFO
    First In, First Out--This is another way to speak of a pipe or ring buffer. On one side, there is a generator that pushes data in and on the other side you have another program that reads the data sent by the generator. The data comes out in the same order it was pushed in. Usually the data are bytes, but it should be a short, long or even a complete event or object.
  • file (126)
  • filter (7)
  • FireFox (9)
  • firewall (9)
  • fix (23)
  • flash (4)
  • float (4)

    float is a type in most software languages referencing an IEEE floating point number. These numbers are generally defined on 32 or 64 bits with three parts: a sign, an exponent and a mantissa. There is also a bias which is not saved in the number. The sign is 0 (positive) or 1 (negative). This means you have a representation of: +0.0 and -0.0. The exponent is about 1/6th the total size in bits. The bias is added/subtracted from the exponent. In the end, it is a signed power of 2 exponent (i.e. exercises a shift on the mantissa.) The mantissa forms the current number.

  • focus (3)
  • font (3)
  • footer (1)

    The bottom of a page, generally something that appears on all the pages such as the current page number, total number of pages, date when it was printed, and the name of the company.

  • hard drive (11)

    A hard drive is a device that save a large quantity of data for later recollection.

    Most hard drives today use a magnetic system to save the data. However, those do get really hot and tend to break easily because they use a mechanical head (after 4 to 5 years.) Yet, they have an incredible capacity with drives that can hold as much as 2Tb.

    New modern drives use flash technology. This is like your USB thumb drive. It does not get hot, it is silent, it has much faster read access (no head to move.) It has two drawback: (1) it has a rather slow write and (2) the capacity is still quite small (at time of writing we are starting to get 128Gb drives...) The price is also much higher, but if you consider that these drives will probably last you twice as long as the magnetic drives and you won't need extraneous cooling systems, overall, it probably still worth it.

  • Hardy (1)

  • Hylafax (2)





  • label (5)

  • lock (6)

    A lock is used to limit the use of shared resources in different ways. When only using the data in read mode, the lock will prevent modifications, but any number of threads and processes can access the data. When in write mode, then only the owner can access the data.

  • locking (1)
  • log (21)
  • logo (4)

    The term logo usually references a small image or icon used to represent a business or product. In computing, there is also the LOGO language, a simplified version of the lisp language, if I may.

  • logon (1)
  • low (4)
  • lsof (2)

    List open files in your Linux system. This command lists all the files that are currently opened. If you are root, you can list all the files opened on the system. Otherwise, only those that you have permission to read or write will show up.

  • LVM (1)



  • navigation
  • negative (1)
  • nested (2)

    In computing, nested means an item defined inside another. It is most often used for loops, a loop can be declared inside another. The one inside is called the nested loop. In particular, two loops can be defined one after another or one inside the other. There is no other way to declare a loop.

  • network (48)
  • network card
  • nice (3)
  • node (15)
  • nop (1)

    nop is the usual abbreviation for the No Operation command often used in assembly language (processor code.) Some times, it is written as noop instead.

  • not (325)

    In programming there are two not operators. One is the logical not that transforms TRUE into FALSE and vice versa. The other transforms bits from 0 to 1 and vice versa. not is also used in documentation with a very specific meaning. Often, the accompagnying verb defines the meaning with more details (i.e. MUST NOT and SHOULD NOT.)

  • Qt (9)

    Qt is a multi-platform development system for servers, command line tools, and graphical applications (GUI). It allows you to create objects that will work on many operating systems with very minimal if any changes.

  • QuickBooks (6)


  • radio (5)

    In the computer world, the term radio is often used for radio buttons.

    Radio buttons are a group of seletable buttons, however, only one of the buttons can be selected in a group. This is called an exclusive choice. Programmatically, when the end user clicks on a button, the computer makes sure that all the other buttons are de-selected.

    The result of the selection is often a number representing the selected button.

  • RAID (2)

    Redundant Array of Independent Disks most often used to have your data duplicated between multiple disks for safety and fast access.

  • RAM (1)
    Random Access Memory. Everyone with a computer uses a lot of RAM to run their processes. This is true of any electronic device with some dynamic capabilities (like your cell phone, pocket calculator, watch with calculator, etc.)
  • reboot (10)

    The action of restarting a computer is called reboot. This reloads the operating system and your different auto-start software.

    There are two types of reboots: a cold reboot and a warm reboot.

    The cold reboot is the one where you turn your computer all the way off and back on. It is considered to be the ultimate reboot which ensures that everything is alright.

    The warm reboot is when you just reboot your operating system. This means some of the hardware parts may not be fully reset as expected in a cold reboot. There are several reasons for this, at times the BIOS of your system does not give the correct signals to all the parts, and at times the signal doesn't propagate to all the parts as it should.

    This is why a warm reboot does not always work (i.e. think when you change a driver and the new driver is not able to properly reset the state of a board or chip... turning the computer all the way off and back on may resolve the problem.)

  • recaptcha (1)
  • record (8)
  • recordset (8)

  • vsftpd (2)

    Very Secure File Transfer Protocol Daemon, an FTP server that allows people to transfer data between computers. It is marked as very secure, at least it is as secure as an FTP server can be (although there has been several security advisories for this tool...)

    Remember that an FTP transfer is rarely using an encrypted pipe (it is possible to use kerberos and SSL to really secure the data transmission) and also because it uses a data stream opened dynamically, it is possible for hackers to spoof a data connection.

  • vulnerability (1)



  • X11 (15)
  • X3D
  • xdebug (1)
  • XML (11)

    Extensible markup language. First mainly used on the Internet, XML was born out of a constrained version of HTML (SGML). It is now used for all sorts of data.


  • zlib (1)

    The Z library is a compression library based on an algorithm that compresses at best in some automated and simle way. For better performance, the entire input file is necessary. Note that you can get better results with other methods, this one is excellent for streaming, however.

  • zoom (3)

    The effect of enlarging (zoom in) or reducing (zoom out) what you see on your screen.

    Note that enlarging generally pixelizes the data unless you have an image with very high precision.

    On the other hand, reducing merges colors together and thus generates a blury image.
