Delphi: Design-Time Component Name Limited to 63 characters (via: Vin Colgin – Google+)

Posted by jpluimers on 2014/05/05

I learned something new today (thanks Vin Colgin) the Delphi Design-Time Component Name is Limited to 63 characters.

Uwe Raabe found out that this an Object Inspector thing due to this constant in DesignIntf.pas:

const
  MaxIdentLength = 63;

It has been probably there since Delphi 1 and has been documented on-line since at least Delphi 2007.

I remember having had long (like 100+ character) identifiers in source code, but not in the Object Inspector.

Now I know you can’t (:

Reminder to self: links to HP C4680 Windows Drivers

Posted by jpluimers on 2014/05/05

Reminder to Self: links to HP C4680 Windows Drivers.

My mom has an HP C4860 all-in-one inkjet printer/scanner/copier.

Soon she will have a new laptop, so here are some links I will need to get that printer installed:

I’m not sure though why “Basic drivers” still need to be close to 40 megabytes.

A Quick Test Drive of Tails, a Privacy Focused Linux Distribution

Posted by jpluimers on 2014/05/05

Fazit:

You’ll probably want a standard OS for day to day tasks, and only use Tails if you really need to remain anonymous.

pickhardt/betty: a command-line like tool like Google Now/Siri for *nix and Mac OS X (requires ruby)

Posted by jpluimers on 2014/05/05

Fun project with potential: pickhardt/betty that was pointed to me by Ilya Grigorik – Google+.

Betty is a natural language (for now: English based) front end for tools like curl, find, wc, whoami, find, etc.

It requires ruby, and runs on *nix or Mac OS X (where it uses osascript for iTunes).

Interesting discussion about generic Dictionaries in Delphi (via: Steve Maughan – Google+ – TObjectDictionary Advice Needed)

Posted by jpluimers on 2014/05/05

There is an interesting G+ discussion thread about generic Dictionaries in Delphi.

It covers the stock TObjectDictionary in the Generic.Collections unit, Spring4D, performance characteristics like O(1), O(log n), etc, and implementation details like fill factors and hashing algorithms.

Worth reading at Steve Maughan – Google+ – TObjectDictionary Advice Needed I’ve been using Delphi for….

Since TObjectDictionary hasn’t changed much since the introduction of generics in Delphi, this discussion is valid for at least Delphi XE and up (and probably Delphi 2010 and 2009 as well).

I’m not sure about these last ones as like Andreas Hausladen, I’m cutting back on the Delphi versions I regularly use, which for now are mainly XE6, XE3, XE and 2007).
