To make managing and analyzing a group of related data easier, you can turn a range of cells into a Microsoft Office Excel table (previously known as an Excel list). A table typically contains related data in a series of worksheet rows and columns that have been formatted as a table. By using the table features, you can then manage the data in the table rows and columns independently from the data in other rows and columns on the worksheet. Note: Excel tables should not be confused with the data tables that are part of a suite of what-if analysis commands. For more information about data tables, see Calculate multiple results with a data table. In this article Learn about the elements of an Excel table Managing data in an Excel table Learn about the elements of an Excel table A table can include the following elements: Header row By default, a table has a header row.

Using Structured References with Excel Tables Structured references make it much easier and more intuitive to work with table data when you are using formulas that reference a table, either portions of a table or the entire table. They are especially useful because table data ranges often change, and the cell references for structured references adjust automatically. This minimizes the need to rewrite formulas as rows and columns are added and deleted in a table, or when external data is refreshed.

Eraser Discussion Forums • View topic - Getting to know Eraser 6 Eraser Discussion Forums • View topic - Getting to know Eraser 6 Read this even if you don’t want to read the manual Who this post is forThis post is for anyone who has just installed Eraser 6 for the first time, including previous users of Eraser 5. If you have just opened the Eraser program, and don’t know what to do next, close the program and read this first. You may be able to do what you want without opening the program at all. There is also a really good basic introduction to Eraser with screen shots here. A warning before we beginEraser has one purpose, and one purpose only: to destroy data and put it beyond recovery. The post does not replace the full user manual, which can be accessed by opening the Eraser Program and clicking on Help. The easiest way to erase files and folders is to use the context menu. If you have a more complex set of files to erase, or you want to be more sure of what you are doing, you may find it easier to use the drag and drop method. The Eraser ScheduleWhen you start the Eraser program, the Schedule opens. David
The shocking truth about Silicon Valley genius Doug Engelbart Tributes to the genius of computer pioneer Doug Engelbart are flooding the web following the announcement of his death at the age of 88. His work transformed the way people use computers today by making them accessible and "personal." His seminal demo of computer graphical user interfaces using a mouse and keyboard transformed people's careers and changed the course of their lives -- even for those that weren't there but heard about it from others! [Doug Engelbart 1968 Demo] However, despite all the accolades and testaments to his genius, Silicon Valley largely ignored his work and he spent decades trying to find funding for his ideas, and even someone to listen to him. Counter-culture and the PC I met him in June 2005 following an event hosted at Xerox Palo Alto Research Center (PARC) in 2005 celebrating the book launch of John Markoff's, What the Dormouse Said: How the Sixties Counterculture Shaped the Personal Computer Industry. I couldn't believe my luck. Pol Pot and the PC revolution… The shocking truth about Silicon Valley genius Doug Engelbart
The impending crisis that is Windows XP and IE 8 The impending crisis that is Windows XP and IE 8 Do you remember what you were doing in October, 2001? You weren’t watching videos on YouTube, updating your Facebook status or even using the term “social media”. It was still the days of web 1.0 and REST was something you did when you were tired. This was a cutting edge device: Websites were “Best viewed in Internet Explorer 5” and looked like this: That 800x600 image was the typical resolution too, it was the most your common 15” CRT screen (in 4:3 aspect, of course) could display. This was a different era, the era in which Windows XP was born. But unlike Raymond and Britney, Windows XP refuses to move on (well at least unlike Raymond), in fact it has hung around until well after its due date. First, the facts: XP still has a massive presence Let’s start with the facts; despite what many people may think, Windows XP is still hugely popular. This is worldwide usage by operating system and clearly XP still has a very strong foothold. IE 8 and Windows XP – inseparable bedfellows

4 Free Software alternatives to Matlab 4 Free Software alternatives to Matlab For those involved in data analysis, numerical computation and taks of that nature, Matlab is an industry standard software to use, though it is not necessarily the best available. The problem is that (Matlab) is commercial and can be expensive. Recently I took a class on Machine Learning and was surprised to find that the professor was not going to use Matlab, but a Free Software alternative called GNU Octave, which was good news because it meant not having to spend money on a proprietary software. Being relatively new to this field, I decided to see what other Free Software alternatives are available. It turns out that there are a bunch of them that are already available in the repository of your favorite distribution. The following list (in alphabetical order) contains four alternative to Matlab that I found: 1. GMT is officially described as a: General purpose calculator program similar in some aspects to BC, Matlab, Maple or Mathematica. 2. 3. Sagemath’s user interface is described as:
Introduction to the Command Line Introduction to the Command Line Commands enable you to do all sorts of powerful things. We will demonstrate this by looking at an everyday task you might be familiar with. If you use a digital camera, you probably have a folder full of images on your computer. Imagine you wish to resize the image profile.jpg so it is 300 pixels wide and then save it as a new image called profile_small.jpg. Using an image editing software, the steps you need to go through might be as follows: Open the image editor from the Applications menu. Using the command line, you can achieve the same result by typing the following: convert -resize 300 profile.jpg profile_small.jpg That is one step in the command line instead of eight steps using the image editor. A single command can do the same thing whether you have 30 images, 300, or 3000. Advantages of Using Commands Many people who give the command line a try are so amazed by its possibilities that they do not even want to go back to a Graphical User Interface(GUI)!

Software Debugging Methodologies When does the course begin? This class is self paced. You can begin whenever you like and then follow your own pace. It’s a good idea to set goals for yourself to make sure you stick with the course. How long will the course be available? This class will always be available! How do I know if this course is for me? Take a look at the “Class Summary,” “What Should I Know,” and “What Will I Learn” sections above. Can I skip individual videos? Yes! How much does this cost? It’s completely free! What are the rules on collaboration? Collaboration is a great way to learn. Why are there so many questions? Udacity classes are a little different from traditional courses. What should I do while I’m watching the videos? Learn actively! Software Debugging Methodologies

Commodore 128 D Black Edition! | WTEs Commodore 8-Bitter Blog Ich bin eigentlich kein Freund von “gemoddeten” Commodore-Rechnern. Die meisten Versuche beleidigen entweder mein ästhetisches Empfinden oder erregen meinen Widerwillen gegen mutwillige Zerstörung von Originalhardware. Wenn jedoch ein umgebauter Rechner ordentlich verarbeitet und gestylt wurde, zolle ich dem gern Respekt. Was allerdings unlängst im Forum64 der Öffentlichkeit präsentiert wurde, löste eine andere Reaktion aus. Für den C128D SD2IEC/LCD Black Edition! Dieser Beitrag wurde unter C128 veröffentlicht.
It seems 1985 was the year that Commodore announced several new computers and peripherals, but never got them to market. In this “Friday Commodore”, I’ll be talking about the Commodore LCD portable computer, the 1572 drive and the C900… 3 very interesting products, that never made it to market. Commodore LCDThe Commodore LCD was presented simultaneously with the Commodore 128 at the Winter Consumer Electronics Show (CES) in Las Vegas back in January 1985 As a 65C02 based computer, many thought it would be a portable 64 (like the SX-64), but this was not the case (it even barely weighed 2,5 kilos). Technically, this computer was a gem as it had one of the best LCD screens at that time, delivering 80 characters on 16 lines (480×128), a built-in 300 baud modem, a professional keyboard with 8 programmable function keys and 32 Kbytes of battery-backed memory to save data. Surely with a superb machine like this, sales would have been sky-high, so why did it never reach the production stage? To market or not to market… Commodore’s prototypes of 1985 | MOS 6502
Willkommen bei eye-print - Kurioses Mein Computer - der Commodore 128 Der C128 gehört zu den herausragensten 8-Bit-Computern, die die Firma Commodore jemals gebaut hat. Das Gerät wurde 1985 erstmals vorgestellt und war als großer Bruder zum C64 geplant. Der C64 galt damals als meistverkaufter Heim-Computer der Welt. C128-Modus: Das Commodore Basic V7.0 besitzt einen Umfang von mehr als 150 Befehlen und wurde gegenüber dem Basic des C64 stark verbessert. Also, alles fing so an: Mein Eintritt ins Computer-Zeitalter kam eigentlich sehr spät. Datenblatt Commodore 128 Nun denn, mit dieser High-End-Maschine begann mein Weg ins Internet.
