Funny Delphi code of the day: on literals

Posted by jpluimers on 2013/12/09

The fact that the [WayBack] 31-character limit on ClientDataSet field and index names is worse, but I just encountered this GetParamNameWODog function in a Delphi 3rd party library:

function GetParamNameWODog(const ParamName: _string): _string;
if (ParamName <> '') and (ParamName[1] = '@') then
Result := Copy(ParamName, 2, 1000)
Result := ParamName;

What’s wrong with using the Length function here?

Yes, SQL Parameter names will probably less than 1000 characters, but then the 1000 literal should be a constant with a meaningful name, and the '@' literal should be too. Read the rest of this entry »

“Hoogtes” waar ik gewoond heb / “Altitudes” of where I have been living

Posted by jpluimers on 2013/12/09

(English translation below)


Veel van Nederland ligt onder zeeniveau, inclusief de meeste plaatsen waar ik gewoond heb, maar ik wist nog niet hoe ver het van N.A.P. “zeeniveau” afweek.

Via toeval kwam ik er achter dat dit on-line heel makkelijk op postcode opvraagbaar is, met een URL als deze:

Je krijgt dan een resultaat als dit:

Volgens AHN2 is de gemiddelde hoogte in postcodegebied 1060NP -1.8 m.

Onderaand de postcodes waar het om gaat.

Vrijwel mijn hele leven was dus beneden zeeniveau, maar ik ben boven zeeniveau geboren (:

En als bonus: AHN Viewer en AHN.


Most of The Netherlands is below sea level, including most of the places I lived, but I didn’t know how far from N.A.P. “sea level” that was.

By coincidence, I found out that it is easy to find this relative altitude by Dutch poascal code with a URL like this:

It will get you a result like this, where the last number indicates altitude:

Volgens AHN2 is de gemiddelde hoogte in postcodegebied 1060NP -1.8 m.

Below is a list of postal codes where I lived or where my post got delivered.

So I lived most of my life below sea level, but was born above it (:

As a bonus, I also found AHN Viewer and AHN.
