I’m looking for an algorithm that converts a list of integers (for instance of…

Posted by jpluimers on 2016/09/28

Got a very quick response Range combo – Paste.ie – Irish For Pastebin on:

I’m looking for an algorithm that converts a list of integers (for instance of pages to be printed) from this form:1,2,3,4,6,7,8,13,14into1-4,6-8,13-14… – Jeroen Wiert Pluimers – Google+

I’ll write some unit tests soon and make it into a unit for testing.

For now it looks exactly what I need. In addition, I learned how this algorithm is called Range extraction – Rosetta Code and the opposite Range expansion – Rosetta Code.

Basically these lists are the format where a user can enter the range of pages to be printed.

The code by Asbjørn Heid uses a Functional record definition allowing for function binding just like in C++ Boost.Bind [WayBack].

Based on that, I made this changeset: https://bitbucket.org/jeroenp/besharp.net/commits/7205b070a4e6457675a083b78d26659da506fc08

atom-keyboard-macros: tried, doesn’t work reliably – anyone who knows a better one?

Posted by jpluimers on 2016/09/28

One of the things I missed in the Atom editor is a keyboard macro recording/playback.

I tried atom-keyboard-macros but it doesn’t work reliably.

Not sure where it fails as the failure patterns are inconclusive.

Anyone having a better experience?

Common Table Expressions: no nesting, but consecutively usage – via Stack Overflow

Posted by jpluimers on 2016/09/28

Common table expressions are awesome. They work in at least Oracle and SQL Server.

You cannot nest them, but you can use them consecutively. Thanks spender for explaining that:

WITH
x AS
(
SELECT * FROM MyTable
),
y AS
(
SELECT * FROM x
)
SELECT * FROM y

The Oracle at Delphi: Set in my ways

Posted by jpluimers on 2016/09/28

A few pieces of Delphi compiler history:

Allen Bauer:

Most notably, the Object Pascal/Delphi compiler is written in mostly C with a smattering of C++, the editor kernel (sans display rendering) and debugger engine (process control/symbol table management) were written in C++. All of which I’ve worked on throughout my 24+ years on that team.

The 16bit compiler was written in pure assembler. The current compiler is written in C. It was derived from an Amiga 68000 Turbo Pascal compatible compiler. It’s never been written in Object Pascal.

That being said, there was an effort several years ago to completely rework/re-architect the compiler. That was done in OP. It just barely got to the “hello world” stage before it was set aside.

Oracle Cross database queries: you need a “database link” for that

Posted by jpluimers on 2016/09/27

I recently learned that you can do cross database queries in Oracle using database links.

You need to prefix your objects with the right schema/owner (for instance dbo.) and suffix with an @ sign followed by the database link name.

This query finds all configured database links:

select * from all_db_links;

Heittps enabled – a hardest part of https-ing a suite of sites is getting rid of “Mixed Content”

Posted by jpluimers on 2016/09/26

“Heittps enabled.” and working for most parts: Verschlüsselung: heise online und Heise-Onlinedienste per HTTPS erreichbar heise.de [WayBack]

A hard part in getting there is fixing “Mixed Content” errors. Report them at https://www.heise.de/newsticker/meldung/Verschluesselung-heise-online-und-Heise-Onlinedienste-per-HTTPS-erreichbar-3331421.html
