UPCOMING MEETING

MAKE LIVE CD FROM ISO

This month we'll take a look at making a live or bootable CD from an ISO file. This is something you may never need to do, but it is something you should be aware you can do if the need arises. We'll provide a couple of examples of why you might need to use a live CD. We'll also discuss what an ISO file is and how it is different from a file archive format like a ZIP file.

For Linux and Mac users support for burning an ISO to a CD is natively supported by utilities included with those OS's. Not so for Windows users. So we'll be taking a look at one way Windows users might make a live CD from an ISO file.

LAST MONTH'S MEETING

Attendance:
13 people in all attended the meeting on Saturday, July 13th. Two of the 13 attendees were virtual attendees via Google+ Hangout video chat.

Main Meeting Q&A:
We began last month's meeting with our normal round of questions and announcements. Among the questions and announcements:

Bill B -

Nelson S -

Tom J -

Rich T -

Ted K -

John M -

Ed C -

Layton F -

Main Meeting Program:
The main meeting presentation topic was "Behind the Scenes" and was presented by John D.

John's focus was on discussing the work flow process of preparing the monthly club newsletter. Brief reference was given to John M's audio processing of the club's audio files and to the monthly updates to the club web site.

John spoke about the transition from last year's word processor derived PDF distribution and hard copy mailings to an HTML based publishing process that results in HTML embedded directly in email and the resultant PDF and ePub eBook spin-offs.

John produces the HTML newsletter on his Windows 7 computer using Amaya with an assist from Notepad++. Amaya is a W3C compliant WYSIWYG (What-You-See-Is-What-You-Get) HTML editor. John creates 3 HTML variants each with a slightly different layout look - one for the club web site, one for emailing, and one used to create the PDF and eBook. He converts the appropriate HTML document to PDF using LibreOffice and also converts the HTML to ePub format using Calibre. His preferred email client is Zimbra Desktop since it is cross-platform software and integrates well with Google mail, contact, and calendar services. He uses the Directory Opus (a.k.a. DOpus) file manager as an FTP client to upload the HTML newsletter to the club web site.

COMPREHENSIVE LIST OF 26 BOOTABLE ANTIVIRUS RESCUE CDS
(for Windows computers; list updated 1st quarter of 2013)
http://www.raymond.cc/blog/13-antivirus-rescue-cds-software-compared-in-search-for-the-best-rescue-disk/

A rescue CD is an additional tool provided by most antivirus companies to assist in removing difficult-to-remove malware without booting in to Windows. This is especially useful when the computer is so badly infected that Windows couldn’t be booted up, or is crawling really slowly and you can hardly run any diagnostic tools inside Windows to investigate and clean the virus.

A huge advantage in using a rescue CD compared to the antivirus installed on your computer is the chances of a successful removal is much higher because the malware is inactive since Windows is not even loaded in the first place. Unlike when a virus is active on the system, it can be very resilient and block any security tools from being run, making it really difficult even for experienced users to delete it from the system.

Rescue CD’s mostly come as an ISO image file that can be written to a compact disc (CD) or installed to USB flash drive which is then used to boot up the computer to run the live operating system in memory. Most of the rescue CD’s provided by the antivirus companies are free while there are a few that are exclusively available only to their paid customers. Here is an extensive list of 26 available rescue CD’s that can be downloaded and used for free.

TOOLS FOR MANAGING EXIF DATA OF YOUR IMAGES
http://www.labnol.org/software/exif-data-editors/14210/

When you capture a photograph with your digital camera, the camera will not only store the current date and time into the image file but even the camera settings.

Exif Metadata in Photographs

The information that is recorded by the camera into the photograph may include details about the camera model itself, the lens that was used, shutter speed, aperture, focal length and so on. Some modern digital cameras and camera phones are GPS enabled and they can therefore save even the location co-ordinates (latitude and longitude) with the photographs.

All this “metadata” is embedded into photographs using the standard Exif format that can easily be read by most image editing programs as well as online photo sharing websites like Flickr and Picasa Web Albums.

1. How to View Exif Data of Images

If you are impressed by a photograph and would like to know more about the camera make and the lens settings that were used when capturing that picture, here’s what you can do do.

Go to Jeffrey’s Exif Viewer and upload the photograph (or if you found the picture on the web, simply copy-paste the image URL). The tool will create a nice summary of all the meta data stored in that photograph along with the location information (see example).

Alternatively, you may use Google’s Picasa, Windows Live Photo Gallery, or any other photo viewer programs to display Exif data from photographs on your desktop.

2. How to Edit Exif Data in Photographs

Why would anyone want to modify the Exif data of photographs? Well, there can be several genuine reasons.

For instance, the internal date of your camera was incorrect and therefore all the pictures were captured with a wrong timestamp. Or you want to add your name to the photograph’s metadata so that people immediately know who the owner is. WIth an Exif editor, you can also geo-tag your photographs manually even if your camera doesn’t have GPS.

You may be a bit surprised but Windows Explorer is actually a wonderful Exif editor. Just right click any image file, choose Properties and click the Details tab. You can now edit a wide range of metadata associated with that image from the camera model to the shooting date to copyright information and more.

Windows Explorer won’t let you edit GPS related information of photographs but Google’s Picasa software is a good choice for doing that.

Finally, if you want to change the Exif data in tons of photographs, you can edit them all in one go using a dedicated Exif editors like Geosetter or Microsoft Pro Photo. Geosetter can pull Exif tags from one photograph and apply them to all your other photos while Pro Photo is more suited for geo-tagging pictures.

Similar stuff can also be done with the help of command like utilities like jHead and ExifTool – these are very powerful tools but implementation is obviously a bit geeky.

3. How to Remove Metadata from Photographs

Sometimes the Exif data of your photographs may reveal more than what you would expect. It may therefore sometimes sense to strip your images of all the meta information before uploading them to the web.

To remove all the metadata from a photograph, just right-click the files inside Windows Explorer and choose Properties. Now click the Details tab and select the option that says “Remove Properties and Personal Information.”

Choose “Remove the follow properties from this file” followed by “Select All” and click OK. All the private metadata tags are now erased from the photograph.

TECHBASIC FOR IOS
http://www.byteworks.us/Byte_Works/techBASIC_App_Builder.html

Write your apps in techBASIC on your iPad or iPhone. That’s where you use them, and that’s where you write them!

techBASIC makes it easy to write apps with interactive graphics, apps that connect to Bluetooth LE and other sensors, and apps that easily do complex math. Just of few lines of techBASIC code often replace what would take several classes in Objective C!

Move your program to your Macintosh and use techBASIC App Builder and Xcode to compile it for distribution, just like any other app.

You can tweak your app, run it in Xcode’s iPhone simulator, or even write apps from scratch in techBASIC App Builder right from your Macintosh.

As with any app, you need to join Apple’s Developer program to compile apps for any iOS device.

You can sell your app on the App Store, distribute it using Ad Hoc distribution, or just move it to your own iPhone or iPad. You don’t need techBASIC to run the compiled app--it works just like any other app.

SOFTWARE WORTH A LOOK

AMAYA HTML EDITOR
(FREE, Open Source, for Linux, Mac, Windows)
http://www.w3.org/Amaya/

Amaya is a Web editor, i.e. a tool used to create and update documents directly on the Web. Browsing features are seamlessly integrated with the editing and remote access features in a uniform environment. This follows the original vision of the Web as a space for collaboration and not just a one-way publishing medium.

Work on Amaya started at W3C in 1996 to showcase Web technologies in a fully-featured Web client. The main motivation for developing Amaya was to provide a framework that can integrate as many W3C technologies as possible. It is used to demonstrate these technologies in action while taking advantage of their combination in a single, consistent environment.

Amaya started as an HTML + CSS style sheets editor. Since that time it was extended to support XML and an increasing number of XML applications such as the XHTML family, MathML, and SVG. It allows all those vocabularies to be edited simultaneously in compound documents.

Amaya includes a collaborative annotation application based on Resource Description Framework (RDF), XLink, and XPointer.

Amaya is an open source software project hosted by W3C. You are invited to contribute in many forms (documentation, translation, writing code, fixing bugs, porting to other platforms...). The Amaya software is written in C and is available for Windows, Unix platforms and MacOS X.

The application is jointly developed by W3C and the WAM project (Web, Adaptation and Multimedia) at INRIA.

Amaya is a complete web browsing and authoring environment:

Amaya lets users both browse and author Web pages
Using Amaya you can create Web pages and upload them onto a server. Authors can create a document from scratch, they can browse the web and find the information they need, copy and paste it to their pages, and create links to other Web sites. All this is done in a straightforward and simple manner, and actions are performed in a single consistent environment. Editing and browsing functions are integrated seamlessly in a single tool.

Amaya maintains a consistent internal document model adhering to the DTD
Amaya always represents the document internally in a structured way consistent with the Document Type Definition (DTD). A properly structured document enables other tools to further process the data safely.
Amaya allows you to display the document structure at the same time as the formatted view, which is portrayed diagrammatically on the screen.

Amaya is able to work on several documents at a time
Several (X)HTML, native MathML (.mml) and SVG (.svg) documents can be displayed and edited at a time.

Amaya helps authors create hypertext links
The editor helps you create and text out links to other documents on the Web from the document you currently are working on. You can view the links and get a feel for how the information is interconnected. This feature is not limited to HTML anchors. With XLink, any MathML and SVG element can be a link too.

Amaya includes a collaborative annotation application
Annotations are external comments, notes, remarks that can be attached to any Web document or a selected part of the document.
