Besides being the Hardy-Ramanujan number, 1729 is also a sphenic number because it is the product of three different primes (7*13*19).



amount of revenue in $ Microsoft made in its first year (D|ONE: 114'000 CHF)



In Mandarin the number 250 (Er Bai Wu) means "moron". Nobody would accept a price or a salary at 250. Explanations about the origin of this expression differ, but a good interpretation seems "on a scale of 1000 you are 250".



Year when D|ONE was established.



Number of different countries of origin for D|ONE team members.



30% Probability that the leading digit in many lists of numbers starts with digit 1 (12.5% that it starts with 3). Called Benford's Law. Detected because some pages in logarithm tables looked used more than others. Used in forensic accounting, specifically in fraud detection.

On top of being the famous Hardy-Ramanujan number, and being a sphenic number, 1729 is also the third Carmichael number, after 561 and 1105. A Carmichael number is an integer n where bn-1 = 1 (mod n) for all b that are prime relative to n. All prime numbers have the Carmichael property.

Pragmatic as the Chinese are, if you take the the "4" (see 4) issue head-on you may turn it into a blessing: 4 times 4 i.e. 4444 means: may you be 4 times lucky in all four seasons.



This number rotates itself:

  142857 X 1 = 142857

  142857 X 2 = 285714

  142857 X 3 = 428571

  142857 X 4 = 571428

  142857 X 5 = 714285

  142857 X 6 = 857142





If you re-arrange things just a little bit, fate may change a lot: Swapping 2 and 5 (see 250) means a significant upgrade: In Mandarin Chinese the number 520 means, "I love you". To make an extra you may also say "520 1314": I love you forever... "13" meaning "this life", "14" meaning "until death" (or "until next life? according to religious preferences).



Distance in kilometers between both D|ONE offices, San Mateo and Zurich.

Interesting but useless info (IBUI)


Number 4 is considered an unlucky number in Chinese, Korean, and Japanese cultures because it is nearly homophonous to the word "death". In order not to take unnecessary risks, in most hotels in Hong Kong or Mainland China there is no fourth floor to choose in elevators (caring also about superstitious Westerners, the 13th floor is usually skipped as well).



The Hardy-Ramanujan number. The British mathematician G. H. Hardy told this story about the Indian mathematician Srinivasa Ramanujan: "I remember once going to see him when he was ill at Putney. I had ridden in taxi cab number 1729 and remarked that the number seemed to me rather a dull one, and that I hoped it was not an unfavorable omen. "No," he replied, "it is a very interesting number; it is the smallest number expressible as the sum of two cubes in two different ways." This anecdote gave this number its name.

    9^3 + 10^3 = 1729
    1^3 + 12^3 = 1729



This number comes up in many discussions among certain professional circles (e.g., programmers). We are not sure why but we have our best analysts working to find out ;-)



Four colors are needed to color a map so that no two adjacent regions get the same color (four-color theorem).

Die Abhängigkeiten von Tabellen, Objekten und Berichten erkennen - mit DBOXS impact.

Wer SAP BusinessObjects (BO) als Reporting System im Einsatz hat, wird mit der Frage konfrontiert, welche Berichte bei einer Änderung des darunterliegenden DWHs oder eines BO Universums betroffen sind.
BO stellt kein Tool zur Beantwortung dieser Frage bereit. Der vorliegenden Artikel erklärt, wie DBOXS impact diese Lücke für DeskI Berichte schliesst.

An Hand von konkreten Anwendungsbeispielen zeigen wir, wie DBOXS impact zu einer besseren Übersicht über die Abhängigkeiten innerhalb des Reporting Systems führt.

Diese Transparenz senkt den Entwicklungs- und Unterhaltsauf-wand beträchtlich. Darüber hinaus erstellt DBOXS impact eine detaillierte Dokumentation, die z.B. beim Umstieg von DeskI auf WebI von grossem Nutzen ist.

Saubere Kundenansprache

Sie haben es sicher auch schon erlebt: ein Verkäufer spricht Sie auf ein Produkt an, das Sie bereits haben. Das Resultat: ein verärgerter Kunde. Bei schlechter Datenqualität bleiben die CRM-Aktivitäten eines Unternehmens erfolglos. Ein systematischer Prozess hilft, Fehler zu ermitteln und die Datenbasis gezielt zu verbessern. So erhalten auch die "richtigen" Empfänger die "korrekte" Botschaft.
