Moving to WordPress.

I’m moving this site to WordPress because Drupal became too messy to administer in some spare time. The fact the database in Drupal 8 became just a storage for application-produced “BLOBs” was the nail in the coffin. Any mis-configuration required too much time to fix, while modules often couldn’t keep pace with the new faster […]

Draytek Stat Processor

DrayTek routers have some advanced configuration capabilities, but their web UI is not one of the best ones around. Especially, it doesn’t display many useful data about VDSL connections which are actually available, but only accessible via telnet/ssh. Moreover they are displayed in a text format only, which makes some of them not very useful. […]

DrayTek Vigor 165 QoS setup

​ It looks the DrayTek Vigor 165 xDSL modem/router supports some QoS features, despite the fact the datasheet does not mention them. They are available from the CLI, and partially in the web UI via a bug in the firewall filter setup page. The CLI gives access to the qos setup, qos class and qos […]

Windows 10 DNS Cache is not just a DNS cache

Disabling the dnscache service in Windows 10 looks to bring a series of issues. I found out when I upgraded a machine from Windows 7 to Windows 10. That machine had the service disabled because it was used in a test environment where often DNS entries changed, and the default cache settings of Windows 7 […]

Why a “case of” statement in Delphi is a dangerous idea

Over and over, people ask the case .. of statement to be expanded to allow strings, i.e. Looks nice, doesn’t it? Sure, but the devil is in the details. Strings are complex data types, and comparing strings is not a straightforward tasks. If you use just a single, simple encoding, and a simple language like […]

Mom, a modal loop ate my service messages!

A colleague of mine was using the “modernized” service implementation I wrote about some time ago. His services needs to be notified when a user logs on/off or locks/unlocks the machine. Everything was fine for a while, until he started to complain it worked for a while, but then, “randomly”, notifications weren’t triggered any longer. Debugging, he […]

Modernize you Delphi Windows application: use Windows 2000 (and later!) services.

No, the title of this blog post is not a mistake. Delphi, including XE7, only implements services using NT APIs obsoleted since Windows 2000. Windows NT was EOLed in 2004, 2000 in 2010, and XP last year, yet Delphi still doesn’t take advantage of the new APIs. What are the advantages? Well, using the “extended” […]

Netgear WNCE3001 DHCP issues, and why luser-oriented interfaces are a mistake

In the past days, I bought a Netgear WNCE3001 wireless adapter to connect my pay TV decoder to the Internet. To configure it, you need to connect it to a PC Ethernet port, and use its configuration wizard to perform the initial configuration – which is just configuring which wireless LAN you want to connect to, and […]

Dopo che una mia lettera riguardante il caso TelexFree è stata pubblicata nella rubrica “Italians” del Corriere della Sera, qualcuno mi ha scritto che TelefFree ha ottenuto il famoso “Chapter 11”. Vero. Ma come al solito gli artisti della truffa vi dicono solo parte della verità, quella che fa comodo a loro. L’ordine della Corte, disponibile qui, dispone di […]
