findstr as alternative for recursive grep search
Posted by jpluimers on 2016/04/27
Usually I use the old Borland grep.exe that still ships with Delphi. Too bad it is 16-bit app which does not recognise Unicode.
FindStr does. Though much slower and with limited regular expression capabilities, can do recursive searches too:
findstr /spin /c:"string to find" *.*
The /spin is a shortcut for these case insensitive command-line options (the full list of possible options is below):
/S Searches for matching files in the current directory and all
subdirectories.
/I Specifies that the search is not to be case-sensitive.
/N Prints the line number before each line that matches.
/P Skip files with non-printable characters.
Sometimes I leave out the /P to include binary files.

XSD enumerations: key value pairs
Posted by jpluimers on 2016/04/26
One of the things you cannot do in XSD, is have string enumerations contain both a key and a value.
But there is a little appinfo trick inside annotation that you can user under some circumstances, for instance when you interpret the XSD:
This file contains hidden or bidirectional Unicode text that may be interpreted or compiled differently than what appears below. To review, open the file in an editor that reveals hidden Unicode characters.
Learn more about bidirectional Unicode characters
| <xs:simpleType name="event_result"> | |
| <xs:restriction base="xs:string"> | |
| <xs:enumeration value="101"> | |
| <xsd:annotation><xsd:appinfo>Syntax error</xsd:appinfo></xsd:annotation> | |
| </xs:enumeration> | |
| <xs:enumeration value="102"> | |
| <xsd:annotation><xsd:appinfo>Illegal operation</xsd:appinfo></xsd:annotation> | |
| </xs:enumeration> | |
| <xs:enumeration value="103"> | |
| <xsd:annotation><xsd:appinfo>Service not available</xsd:appinfo></xsd:annotation> | |
| </xs:enumeration> | |
| </xs:restriction> | |
| </xs:simpleType> |
appinfo is the application counterpart of documentation: both can contain any xml, but appinfo is aimed at machines, whereas documentation is aimed at humans.

Happy birthday .nl top-level domain for getting 30 today
Posted by jpluimers on 2016/04/25
I remember this happening when I was almost starting the studies at University: the Netherlands getting their country code top-level domain in 1986: at first mostly universities and research institutions were getting their .nl domains.
Today 30 years ago .nl came into existence and the first research institution domain here was cwi.nl (the research institution for math and informatics) as it handled the registrations (for years Piet Beertema did that, even before he hooked CWI to NFSnet in 1988).
This was the era of uucp – way before the web – which handled a lot of the mail traffic, but not the only one as back-then my HLERUL5.bitnet email address wasn’t even tied to the .nl dmain back then: it ran over DECnet based Mail-11 software. So it took a few more years before I got a .nl email address that the university and one of the reasons I still use a jeroenp account on many systems, for instance a few more years later when I got jeroenp@dragons.nest.nl at home.
This was way after the first commercial companies got their .nl toplevel domains, for instance and.nl was registered very early on (and Jos Horsmeier was very active).
So: happy birthday .nl and a bit thank you for all the people involved in getting .nl into existence.

Mac OS X Time Machine – Stuck on “Preparing Backup”
Posted by jpluimers on 2016/04/25
For one of my USB backup drives, Time Machine was stuck showing “Preparing Backup”.
tmutil (which has a lot of undocumented parameters) helped me out.
tmutil status would not show any change for hours either:
retinambpro1tb:~ root# tmutil status
Backup session status:
{
BackupPhase = ThinningPreBackup;
ClientID = "com.apple.backupd";
DateOfStateChange = "2015-05-04 19:27:31 +0000";
DestinationID = "01AE12C7-1D3E-469E-BE7E-32DA30F0030E";
DestinationMountPoint = "/Volumes/Elements2TB1";
Percent = "-1";
Running = 1;
Stopping = 0;
}
...
retinambpro1tb:~ root# tmutil status
Backup session status:
{
BackupPhase = ThinningPreBackup;
ClientID = "com.apple.backupd";
DateOfStateChange = "2015-05-04 21:13:28 +0000";
DestinationID = "01AE12C7-1D3E-469E-BE7E-32DA30F0030E";
DestinationMountPoint = "/Volumes/Elements2TB1";
Percent = "-1";
Running = 1;
Stopping = 0;
}
So I:
- removed the .inProgress file found by
ls -al /Volumes/Elements2TB1/Backups.backupdb/`scutil --get ComputerName`/*.inProgress - rebooted with the USB drive attached
- waited for spotlight to complete
- manually started a backup
- verified it made progress using tmutil (you need to run that as root, for instance with
sudo su -)
And it indeed made progress and finished:

Anyone that installed D10.1 had the new installation dialogs that Embarcadero brags about…

Conclusion:
- Web Installer = new installer, but forgets some Active X parts
- ISO Installer = old installer, but works fine
