Myth - 72dpi For Web Images

Every time I read articles or tutorials about saving images for Web pages or sending through e-mail they always mention saving the images with a resolution of 72DPI or Dots Per Inch. The interesting fact about this suggestion is that a computer monitor doesn’t deal with dots or inches, but rather with pixels.

The resolution of a monitor is indicated as two numbers: [number of pixels for width]x[number of pixels for height]. For example, resolutions are indicated as 800×600 or 1024×768. You notice no mention of dots or inches because a monitor only cares about the number of pixels. This means that when creating images for viewing on a monitor it is important to pay close attention to the size of the file in pixels.

Disks - Detailed Introduction

  • Secondary storage device of choice.
  • Main advantage over tapes: random access vs. sequential.
  • Data is stored and retrieved in units called disk blocks or pages.
  • Unlike RAM, time to retrieve a disk page varies depending upon location on disk.

    • Therefore, relative placement of pages on disk has major impact on DBMS performance!

Components of a Disk

  • The platters spin (say, 90rps).
  • The arm assembly is moved in or out to position a head on a desired track. Tracks under heads make a cylinder (imaginary!).
  • Only one head reads/writes at any one time.
  • Block size is a multiple of sector size (which is fixed).

Stumping The Jump

Stumping the “Jump” in Spreadsheet and Document Creation Programs: A Smarter Way to Select Needed Text and/or Data

Perhaps one of the most annoying little “bugs” in most Microsoft software programs (and several other non-Microsoft document/spreadsheet programs) is when the cursor/user interface “jumps” far beyond where you wanted it to go. This tendency is often called “jump”. (For example, “Oh shoot – my cursor just jumped ahead five pages into my Word document – I just wanted to select the next three paragraphs!”) Jump happens when you are using a program like Microsoft Word or Excel and you are trying to select text or data into your clipboard, and as you start to scroll through the data, the cursor suddenly “jumps” much further into your document than you intended. Suppose, for example, that you are trying to select data from rows 30 to 240 in an Excel spreadsheet, and as you start to scroll down from row 30 you suddenly find yourself on row 2754 – this is “jump”!

The Hidden Hindrance To Virtualization Performance

As a recent article shows, virtualization is taking over in a big way. This technology allows better use of system resources by allowing multiple operating environments on a single physical hardware platform. More specifically, it is the creation of one or more virtual instances of a “guest” operating system on top of a “host” operating system, or in some cases directly on top of a specialized software layer. It allows numerous virtual machines, either standard PCs or servers, to operate and appear as independent machines when in fact they’re operating off of a single hardware platform.

How To Defend Yourself When On Trial

When you are on trial how should you defend yourself? Notice I say, when, and not if!

This man, Paul appears in another courtroom, and we are given quite a descriptive insight as to how he acts and behaves before his accusers.

Reach for your New Testament and check out the detail in Chapter 24.

Paul, on trial in Caesarea, by the Mediterranean Sea, is invited to reply to the accusations which have been made against him. Here we see a man of God who has a clear conscience in the presence of God, and before his accusers.
