Windows PPTP – How to Create a VPN Server on Your Windows Computer Without Installing Any Software

Posted by jpluimers on 2016/07/18

Windows has the built-in ability to function as VPN server, although this option is hidden. This trick works on both Windows 7 and Windows 8. The server uses the point-to-point tunneling protocol (PPTP.)

One day this might come in handy though I need to investigate a bit more on PPTP security issues first: might need to go for L2TP/IPsec instead.

Later: indeed, I should follow Don’t use PPTP, and don’t use IPSEC-PSK either (via: CloudCracker blog)

PowerPoint 2013: when Date, Slide Number or Footer don’t show – via: Academic Technology @ Palomar College

Posted by jpluimers on 2016/07/18

Coming from an Office pre 2000 background, I’m still amazed at how will things are hidden in modern Office versions.

Take the page numbers not showing on slides – Microsoft Community.

I bumped into that recently as well on a new blank presentation:

You see the placeholders at design time, but they don’t show up at presentation time.

The obvious action for me: Right click on each to see if there is anything about special formatting or hiding. It doesn’t work.

What does work is to:

  1. Go to the top of the Slide Masters
  2. Click the Ribbon
  3. Choose Insert
  4. Choose Text
  5. Choose Header & Footer
  6. Put a check marks for the place holders you want to be visible

1970 Becker Mexico AM-FM Cassette Car Radio showing operation & sound – YouTube

Posted by jpluimers on 2016/07/15

This is the radio in our W116 450SEL 6.9 (pictures are at Flickr: mb450sel69).

Still need to figure out how we can connect a mobile phone or AUX to it.

Research research…

Note there were earlier and later models of this:

This is ours:

FireFox full version direct download link

Posted by jpluimers on 2016/07/15

When firewalls, proxies, etc prohibit the boots-trapper that upgrades an existing Firefox or download stub (like “Firefox Setup Stub 38.0.1.exe”) installs a fresh one to function correctly:

https://download-installer.cdn.mozilla.net/pub/firefox/releases/38.0.1/win32/en-US/Firefox Setup 38.0.1.exe

(replace the version number with the current one; replace spaces with %20 when needed)

Somebody lost hope – see the image on the right – or these two lines at GitHub.

Those are the OCR-ed and hand corrected sources from the stack of paper below: chrislgarry/Apollo-11: Original Apollo 11 guidance computer (AGC) source code digitized by folks at Virtual AGC (http://www.ibiblio.org/apollo/).

Some great links from the above Reddit thread:

Git Cheat Sheet

I had seen the bitmap Git Cheat Sheet referenced numerous times, so I went searching for the source and found it under Creative Commons 3.0 license at http://byte.kde.org/~zrusin/git/ which has the Vector Image Source by Zack Rusin.

Interesting trick posted by Lars Fosdal on keeping IDE user specific defines

Posted by jpluimers on 2016/07/13

Via Lars Fosdal:

In Tools|Options, Environment Options, Environment Variables – under User Overrides, add a new override

Variable name: DCC_Define

Variable value: billmeyer

This causes a define for billmeyer to exist for anything that you compile in your IDE, across all units, all projects.

Which means you can sprinkle your code with

{$ifdef billmeyer}{$hints on}{$endif}

or

{$ifndef billmeyer}{$hints off}{$endif}

or even isolate out the parts of the code that currently is in development so that it doesn’t get built in the build system.

I believe it was +Uwe Raabe who revealed this gem to me.

Delphi include files and the search strategy are different for the compiler and IDE

Posted by jpluimers on 2016/07/12

Recently I bumped into a thing that I’d long forgotten: the Delphi compiler treats searching for include files (any files used with the {$I} or {$include} directive differently:

  • The compiler first searches the directory where the file that is including resides and then uses the project and IDE search paths.
  • The IDE only uses the project and IDE search paths.

This means that when you press Ctrl-Enter on the filename to be included you might edit a different file than the compiler will include.

So when a product has multiple include files with the same name in different sub-directories, then you must modify them all.

I’m not sure this is a bug or feature, so Embarcadero is free to put this in either their QA system or documentation system.

Delphi keeping EXE locked; some links

Posted by jpluimers on 2016/07/12

For my own reference when coping with “[dcc32 Fatal Error] F2039 Could not create output file” which happens with a lot of Delphi versions:

As a temporary measure (in the end you have to restart the IDE), I often use Process Explorer to force close the open handles from bds.exe to the EXE.

It also happens intermittently using Visual Studio, where  devenv.exe keeps handles locked. Same Process Explorer trick applies there too.

You can do similar tricks with LockHunter or Handle.exe.
