Jark/FTDISample: Note: As of version 10556.0 the ftdi driver does no longer seem to work. A sample application showcasing the FTDI D2XX driver use in Windows Universal projects (UWP). This sample is tested on the Raspberry PI 2 with Windows IOT installed and a FTDI FT232R usb-to-serial adapter.

Yeah, I couldn’t get this working either. I’m not sure where ReadTimeout is actually used by the SerialDevice class internally. But I did end up getting something working by copying the timeout to a

grep: searching for pipes, optional characters
Posted by jpluimers on 2016/09/22
For my own reference as RegEx is a write-only language:
Search for pipes means just back-slash escaping them:
grep "\|S\|" products.txt > s-rated-products.txt
Search for optional charactes (in this case searching for both the singular and plural form of a word) can be done by grouping the optional part in parentheses:
grep -i "Movie(s)?" products.txt > movie-products.txt
Search for either OR:
grep -E "foo|bar" products.txt > foo-or-bar-products.txt
egrep "foo|bar" products.txt > foo-or-bar-products.txt
Note that the Borland grep does not support the OR syntax, but egrep does.

SPAM – Garantiebellen – +31172749040 – ‘Hang op! Klik weg! Bel uw bank!’ – #KVK doe er wat aan!
Posted by jpluimers on 2016/09/21
Onder het mom van ‘Hang op! Klik weg! Bel uw bank!’:
Ik werd net gebeld door +31172749040 die zich bekend maakten als “Garantie Bellen” en onder het mom van “partner van KPN” je proberen een nieuw abonnement met lagere tarieven aan te smeren.
Hun web-site meldt dat ze in Rotterdam zitten:
Hun algemene voorwaarden echter Utrecht:
Garantie Bellen, Churchilllaan 11, 3527 GV in Utrecht
Op de hele site geen informatie van het handelsregister, dus ze plegen sowieso een economisch delict:
Het niet naleven van de verplichting om het KvK-nummer te vermelden is een economisch delict (art. 1 sub 4 WED). Het is een overtreding die wordt gestraft met hechtenis van ten hoogste zes maanden, taakstraf of een geldboete van de vierde categorie (dat wil zeggen ten hoogste €19.000,-).
Die heb ik inmiddels zelf gevonden: 61233927 met als informatie:
Naam: To the Max Callcenter B.V. Vestigingsadres: Westblaak 142 Vestigingsplaats: 3012KM Rotterdam KvK-nummer: 61233927 Vestigingsnummer: 000030351928 Soort Inschrijving: HoofdvestigingTo the Max Callcenter B.V.Hoofdvestiging

Tools to view Blue Screen info and Windows/Application Crash Reports
Posted by jpluimers on 2016/09/21
These NirSoft tools helped me finding out about some crashes that never made it to the event log:
- Blue screen of death (STOP error) information in dump files.
- WinCrashReport – Displays a report about crashed Windows application
- AppCrashView – View application crashes (.wer files) in Windows 7/Vista
- Get information about Windows software that stopped responding/freezing (hang)
At first I thought my own software development caused them, but In the end they were caused by buggy video drivers.

Yes Dorothy, the .NET System.Array Class can throw you a NotSupportedException
Posted by jpluimers on 2016/09/21
It’s been in the System.Array class forever, but remarkably few people do know that it can throw you a NotSupportedException (for instance when calling Add, Insert, Remove, etc).
It does because it implements IList, but not all methods implemented from IList are valid.
And it also indicates that, as the IList Properties allows for IsFixedSize to return false.
A similar case is there for IsReadOnly: then you cannot even modify the values.
Ever since I started teaching .NET/C# classes almost 15 years ago, I warned:
beware when you use IList as not everybody implements all methods.
