Do you wish there was a easy-to-use application that could keep your data files backed up as you worked, without
having to manually update the backup every time? Or would you like to be able to install a backup system for
someone else (e.g. family member, friend, employee) who might not otherwise want to be bothered with making backups,
so that it gets done automatically for them? BackupCat has been designed to satisfy those needs!
BackupCat includes the following features:
- Easily set up a list of individual folder paths to be backed up, by using the "Common Backup Pairs Wizard",
or by using the "Add a New Folder Backup Pair" dialog and browsing to the source and destination folder
to add a new backup folder pair to the list.
- Once set up, it runs automatically after you log on, unobtrusively in the background without slowing down other applications.
- Makes backups fully under your control, easily verified and stored in their original format.
- Respond automatically to changes in backed up folders on NTFS drives to immediately copy the changes to the backup.
- Runs periodic scans, which provide support for unmonitored sources such as network shares and non-NTFS drives.
- Runs scans on demand.
- Runs over wired and wireless networks.
- User configurable clone/mirror or update modes.
- User configurable settings include startup delay, periodic poll interval, logging, and background priority.

Visual Colour Selector
Visual Colour Selector previews colours from 8 built-in colour definition (palette) files, including the predefined colours of CSS3
recognised by a wide range of browsers, the X11 colours (a set of 502 distinct color values with some used as the basis for the CSS colours),
the wxColourDatabase colour database from wxWidgets (a cross-platform C++ graphical user interface software library),
and two third-party palettes designed with suitability for colour-blind people in mind. Users can also add their own palette files
using a simple text format.
You can copy colour names and RGB values in decimal or hex format to the clipboard for use in coding, web design etc.
You can create a subset of colours from any number of colour definition files as a custom selected palette,
and then filter the selected palette to get a palette of colours optimised for visual colour separation using
CIE delta-E colour separation standards, or generate an optimised palette from randomly generated colours
with user-specified ranges of hue, saturation and value/luminance in HSV or HSL colour space.
Colours are also shown simulated as seen by people with colour deficiencies (protanopia, deuteranopia, and tritanopia) and
you can generate optimised palettes accounting for these colour deficiencies.
You can evaluate contrast between light and dark colours in a filtered palette according to WCAG 2.0 (ISO/IEC 40500:2012)
criteria, with the option to evaluate the contrast accounting for colour deficiencies.
WCAG accessibility is increasingly a requirement for government websites,
e.g. US Section 508 federal websites and digital content, the Canadian Accessibility for Ontarians with Disabilities Act (AODA),
UK government Digital Service Standard, EU commission websites, Australian Disability Discrimination Act,
Hong Kong government websites, Indian government websites, etc.
You can also preview image files, including simulation of colour deficiencies.
You can download the free version of Visual Colour Selector below (some limitations apply). It should run on Windows 7, Windows Server 2008, and later versions,
and the Linux version should run on distros Ubuntu, Debian, Mint and Fedora.

wxLeakyBin is a graphical tool to assist in identifying even small memory leaks quickly.
wxLeakyBin allows you to view system and process memory usage graphically in fine detail.
By using a magnified scale factor, and the option to plot commit charge for individual processes
as well as the system, you can detect even small memory leaks that are too small to show up on the regular Task Manager.
You can measure changes in memory usage and rates of change using markers and linear regression on the graph,
which has calibrated grid intervals.
Update speeds can be set down to 100ms intervals, 5 times faster than Task Manager.
It should run on Windows 7, Windows Server 2008, and later versions.

Circuit Scribe Help
With Circuit Scribe software, you can:
- Create and print circuit diagrams (schematics)
- Create screen-capture graphics for use in illustrating web pages
- Export netlists to PCB layout software
- Export netlists to Spice circuit simulation software
- Export Bill of Materials lists
- Automatically create new component outlines by importing IBIS files
Circuit Scribe's line and colour editing features allow you to create illustration quality
layouts as well as doing routine circuit design and documentation.
To illustrate this, I created an example of a circuit illustration (part of which
is shown below), based on an illustration that I created originally in 2001
(in the page thumbnail on the right) for publication
(Seymour C J, "The Road to High Frequency Applications for SiC Power Diodes",
Power Electronics Europe, Issue 6, 2001).
The example started with standard general library components from the built-in library file, which were then modified to thicken lines and include different fill
colours in certain component objects, creating the library "Illex.lib", which is
provided in the library samples when Circuit Scribe is installed, and the circuit
layout was further augmented with text and drawing elements,
resulting in the example file "PwrOsc.cct".

The following extract shows part of the original "PwrOsc.cct" schematic:

RFProp is a Windows propagation calculator for the transmission path between an RF transmitter
and a receiver. It is aimed mainly at free-space and space-wave applications, such as
are encountered in VHF, UHF and microwave communications, and also in satellite communications.
A knife-edge diffraction calculation is also included which when enabled allows the effects of
a hill or other obstruction to be taken into account.
This updated RFProp with several improvements for better compatibility with Windows 7.
It is intended for installation on Windows XP, Windows 7, or later operating systems.
Windows Download: rfp120.zip, Version 1.20, updated March 20th, 2011, 401KB
RFProp version 1.01 was initially distributed at the 1996 Radio Solutions Conference at the National Exhibition Centre,
Birmingham, England, at which the author delivered a paper on spread spectrum radio. RFProp was part of a
free promotional floppy disk handed out at the Central Research Laboratories stand in the industry
exhibition associated with the Conference.
Version 1.10 (January 4 2004)
32 bit version of RFProp, with an improved NSIS installation program.
Non-standard .ASC file extensions were replaced by .TXT, and the units for "Margin at spec. range"
have been corrected from m to dB. File-save dialog was a considerable improvement on the
old 16 bit one. Installer updated in 2005 because of false positives from AVG on the old one.

WinShoe IRC Client
WinShoe is an Internet Relay Chat (IRC) client for connecting to IRC networks and finger servers on Windows PCs.
Features multiple IRC network connections, aliases and popups, scripts, text searches, wheel mouse, Ident and
finger servers, browsing URLs, three colour modes compatible with most existing software, 16 and 32 bit
versions. Works on Windows XP, 7 and 10.
IRC is based on a well-established internet protocol that enables people to chat by entering lines of text for display in a common text
window or 'channel' (also called 'chat room'). It is very low bandwidth protocol and can therefore continue operating even in adverse
networking conditions. When you run an IRC program, you connect to a server on the Internet. The server redistributes
everybody's chat so that all can see it.
Normally, once connected to an IRC server, users join a well-known channel to chat with others. Topics vary
and cover a range of subjects, from not-safe-for-work topics (so be warned, take care who gets access to the software!)
to politics, software technology discussions, and share trading.
