Protecting MS Excel Worksheets with passwords can be user-friendly. No one fiddles with the configuration. Yet, if you need to administer the sheets, lost passwords are a pain. So, in case you need to unprotect a sheet – and obviously only if you have the right to do so! – the folling VBA code snippet can help:

Sub LittleMagicPasswordBreaker()
    Dim i As Integer, j As Integer, k As Integer
    Dim l As Integer, m As Integer, n As Integer
    Dim i1 As Integer, i2 As Integer, i3 As Integer
    Dim i4 As Integer, i5 As Integer, i6 As Integer
    On Error Resume Next
    For i = 65 To 66: For j = 65 To 66: For k = 65 To 66
    For l = 65 To 66: For m = 65 To 66: For i1 = 65 To 66
    For i2 = 65 To 66: For i3 = 65 To 66: For i4 = 65 To 66
    For i5 = 65 To 66: For i6 = 65 To 66: For n = 32 To 126
    ActiveSheet.Unprotect Chr(i) & Chr(j) & Chr(k) _
        & Chr(l) & Chr(m) & Chr(i1) & Chr(i2) & Chr(i3) & _
        Chr(i4) & Chr(i5) & Chr(i6) & Chr(n)
    If ActiveSheet.ProtectContents = False Then
        MsgBox "One usable password is " & Chr(i) & Chr(j) & _
            Chr(k) & Chr(l) & Chr(m) & Chr(i1) & Chr(i2) & _
            Chr(i3) & Chr(i4) & Chr(i5) & Chr(i6) & Chr(n)
        Exit Sub
    End If
    Next: Next: Next: Next: Next: Next
    Next: Next: Next: Next: Next: Next
End Sub

Just open the VBA editor ([Alt]+[F11]), copy the snippet into a new VBA Module of the Excel worksheet, and execute (Run or [F5]).

The qaul.net-software implements a redundant, open communication principle, in which wireless-enabled computers and mobile devices can directly form a spontaneous network. Text messaging, file sharing and voice calls are possible independent of internet and cellular networks. Qaul.net can spread like a virus, and an Open Source Community can modify it freely. It runs on MacOS, iOS, Windows, Ubuntu, Android alike: https://github.com/qaul/qaul.net.

A small application to simplify the process of creating symbolic and hard links in Windows 7 and Windows 8 (likely Vista too). It is a GUI for the MKLINK command in Windows, which makes creating the links much easier.

The program requires administrator permissions due to use of the command prompt, so you should run it as an administrator if you experience any problems.

Note: It is not possible to create a hard link from a network share. You must use a symbolic link instead: https://sourceforge.net/projects/symlink-creator/.

HTTP File Server, otherwise known as HFS, is a free web server specifically designed for publishing and sharing files. The complete feature set differs from other web servers; it lacks some common features, like CGI, or even ability to run as a Windows service, but includes, for example, counting file downloads. It is even advised against using it as an ordinary web server.

HFS is a small HTTP file server, aimed at mostly sharing files for download.
The official documentation describes HFS as:

  • HFS (Http File Server) is file sharing software which allows you to send and receive files. You can limit this sharing to just a few friends, or be open to the whole world.
  • HFS is different from classic file sharing because there is no network. HFS is a web server which uses web technology to be more compatible with today’s Internet.
  • Since it is actually a web server, your friends can download files as if they were downloading from a website using a web browser, such as Internet Explorer or Firefox. Your users don’t have to install any new software.
  • HFS lets you share your files. Most web servers are used to publish a website, but HFS is not designed to do that. You are, however, free to use it in any way you wish, – but at your own risk.
