Old and invalidated by the Microsoft RDP client in the Mac App Store: Best RDP client for Mac OS X Lion and up
Posted by jpluimers on 2014/10/10
Back when I wrote this mid 2013, this was the best Windows RDP overview article I could find: Best RDP client for Mac OSX Lion.
And it all got invalidated when finally (after years of silence), Microsoft released AppStore versions of the RDP client for both Mac OS X and iOS:
Microsoft Launches ‘Remote Desktop’ Apps for Mac and iOS – Mac Rumors.
So I tried the Mac App Store – Microsoft Remote Desktop that runs on OS X 10.6.0 or later for more than a year, and I like it a lot.
This is what the AppStore version improved over the classic Microsoft Remote Desktop Connection:
- It has more regular updates.
- It remaps the Mac Command key to the Microsoft Windows logo key.
- It uses the new RDP protocol version features which means fast response, even on slow network connections and better security.
- Full screen support is superb.
- Clipboard integration just works.
- It is really stable.
Just so you know about alternatives,
for the record, this is the draft I wrote in 2013: Read the rest of this entry »

Version control: branches, tags, merging, the folder you work in. Some SVN links.
Posted by jpluimers on 2014/10/09
When using any version control system, understanding which idiom you should follow to do proper branching, merging, tagging, etc is key to your process, and the most difficult thing to get a feel for.
For me, the most confusing part is that branches, tags, and the trunk are directories (both on your development system and the SVN server), and it is hard to see which local directory is switched to what remote one.
As soon as I understood that this was the most confusing aspect for me, I could focus on it and handle it much better.
For SVN (and TortoiseSVN), these links proved to be very valuable for me: Read the rest of this entry »

The CD pseudo environment variable in batch file: do not overwrite it with a real one!
Posted by jpluimers on 2014/10/08
I never realized you could overwrite the CD pseudo environment variable. If you do, the automatic value of the pseudo variable will not be udpated any more:
You have at some point set the CD variable explicitly. If you do this it will no longer automatically reflect the current working directory. To undo this, set it to empty:
set CD=
Thanks Jonathan and … for explaining this in both your answers.
Thanks to another answer by Endoro I now also know of the %=C:% pseudo variable (you have one per drive letter) that indicate the current directory per drive letter.

Delphi: RandomizeIfNeeded
Posted by jpluimers on 2014/10/07
Calling Randomize too often can make your Random numbers even less random.
Sometimes having the Randomize call in a unit initialization section is not practical.
Hence this little method that I think I first wrote back in the Turbo Pascal days:
procedure RandomizeIfNeeded();
begin
if RandSeed = 0 then
Randomize();
end;

Great answer on “windows – What encoding/code page is cmd.exe using” (via: Stack Overflow)
Posted by jpluimers on 2014/10/06
I just found this [Wayback] great answer (which by now regrettably is deleted; the previous Wayback link still has it) by [Wayback] Јοеу a.k.a. Johannes Rössel on [Wayback] What encoding/code page is cmd.exe using.
The whole answer is worth reading, so I won’t quote only some bits.
Edit 20210609: the answer now has been replaced by an even more detailed answer [Wayback] by [Wayback] andrewdotn. Also recommended reading. The summary of the new answer is this:
The moral of the story?
typecan print UTF-16LE files with a BOM regardless of your current codepage- Win32 programs can be programmed to output Unicode to the console, using
WriteConsoleW.- Other programs which set the codepage and adjust their output encoding accordingly can print Unicode on the console regardless of what the codepage was when the program started
- For everything else you will have to mess around with
chcp, and will probably still get weird output.

Windows: authenticated command-line download from IIS server wget: no, cURL: yes.
Posted by jpluimers on 2014/10/03
Had to download a bunch of stuff over the command-line from an IIS server that was using authentication. Not basic authentication, but NTLM authentication.
wget kept failing, even wget 1.10 that usually does NTLM quite OK (but up to 1.10.2 has a security vulnerability so you should not use wget 1.10 any more).
So I installed a Windows x86 cURL binary, and downloaded+copied the root certificates, then did some reading on the command-line switches.
Without any, cURL does http basic authentication. But a Windows server usually expects NTLM authentication (hardly documented, but it uses the Negotiate protocol).
When not using NTLM, both would show (wget -d, or curl -v) this in the output, indicating you should use NTLM authentication: Read the rest of this entry »

Some cool visual traceroute sites/mashups
Posted by jpluimers on 2014/10/02
It is always cool to see some mashups: apart from great examples, they also make for some good research material.
- Traceroute.V – CodeFromThe70s.org.
(next to JavaScript, it also requires Java. An explanation how it works reveals it is using a quite old IP->geolocation DB) - Email graphic traceroute.
(parses email headers to traceroute the SMTP route the email took) - Insert an url (example: www.parsec.it) and locate where the server is (webserver, mailserver,…) on Google Maps.
(Whereis translates an IP address or DNS address to a geolocation on Google maps) - Google Maps Hacks.
(uses the Whereis to map the output of a traceroute/tracert command into a Google map) - IP Address Lookup, Reverse IP Lookup and RBL Lookup.
(maps IP address or DNS address to Google maps) - Visual Trace Route Tool – Find, Track, and Map the Route to an IP Address.
(traces either from the server, or through a proxy)

Delphi hinting directives: deprecated, experimental, library and platform
Posted by jpluimers on 2014/10/01
I’ve been experimenting with the Delphi hinting directives lately to make it easier to migrate some libraries to newer versions of Delphi and newer platforms.
Hinting directives (deprecated, experimental, library and platform) were – like the $MESSAGE directive – added to Delphi 6.
Up to Delphi 5 you didn’t have any means to declare code obsolete. You had to find clever ways around it.
Warnings for hinting directives
When referring to identifiers marked with a hinting directive, you can get various warning messages that depend on the kind of identifier: unit, or other symbol. Read the rest of this entry »

NTCore: interesting site about about system internals and software security
Posted by jpluimers on 2014/09/30
I recently bumped into the NTCore website by Daniel Pisti.
At a client without my own VMs, I wanted to create a DebugBreak like function in Delphi, which I remembered from my Turbo Pascal days to be something like Inline($CC). So searching for both Delphi and INT 3, I found an EXE injection page at NTCore.
In Delphi, you can do this with a procedure like this, which cannot be inlined because it has an asm block:
procedure DebugBreak();
asm
int 3
end;(Reminder to self: sort out what to do here to break on an iOS device; Xcode has an alternative)
The site has information about system internals and software security posted as articles until 2009, when he switched to blog posts. Besides that, he has written a bunch of interesting articles at CodeProject. Read the rest of this entry »
