In questo secondo capitolo della serie egg box per arduino (una lampada a led costruita con 2 scatole di plastica delle uova), riscriveremo il codice in modo da utilizzare un sistema operativo real time chiamato NilRTOS e disponibile su Github; in particolare mostrer貌 un semplice sketch che 猫 in grado di produrre un piccolo accordo ed accedere tre luci rispetto ad un ritmo, mentre una quarta, di colore rosso, si accender脿 rispetto ad una cadenza diversa.

Programmare Arduino 猫 molto divertente, ed in questo articolo voglio mostrare come creare una semplicissima lampada luminosa. Questo esempio sar脿 anche il pretesto per mostrare differenti implementazioni software dello stesso progetto (in prossimi post)
Questo progetto 猫 volutamente molto semplice, e non si serve di nessun sensore.

I stumbled upon a very brain-f**k error on Oracle 10g on these days.
Context: the following query [sql]SELECT * FROM (
SELECT TO_NUMBER(CUSTOMER_ID) AS SNDG FROM BAD_CODES_TABLE WHERE
AND I_LIKE=UPPER(‘STATIC_CONDITION’) AND CUSTOMER_ID NOT LIKE ‘%P%’ ) S WHERE TO_NUMBER(S.SNDG) >2000[/sql] could trigger a Invalid number if CUSTOMER_ID column contains invalid numbers.Why?
Well鈥f you ask to “explain plan”, you will get something like
- a table full scan
- Filter Predicates AND
- I_LIKE=UPPER('STATIC_CONDITION')
- TO_NUMBER(S.SNDG) >2000
- CUSTOMER_ID NOT LIKE '%P%'
- Filter Predicates AND
Read More - a table full scan

How I Structure My Flask Applications Flask has been my preferred web framework as of late. I think it has a great core feature set and Armin, the main author, has done well to keep its API minimal and easy to digest even for developers that are relatively new to Python. However, given that it is a rather minimal framework, it can be often difficult to decide on how to structure an application after it reaches a certain level of complexity. It tends to be a common question that comes up in the #pocoo IRC channel.In this article I intend to share how I structure Flask applications. To help support this article Ive written a very basic application that Ive arbitrarily named Overholt. If you plan on following along I recommend having the source code open in your browser or a code editor.
