[Painless].[SQLServer].[Performance] (A Java & 2008 R2 troubleshooting short novel)

Non sono un DBA ma uno sviluppatore, principalmente Java. Prima di 2 mesi fa l’apice della mia conoscenza dei database erano indici e sequence. D’improvviso un’applicazione “legacy” ha iniziato ad essere inutilizzabile per problemi di performance. Se stai scoprendo il piacere di query lente, deadlock, stalli dell’applicazione, connection leak e ti confondono gli isolation level potresti portare a casa qualche utile spunto.

Una diretta dalla trincea con tattiche probabilmente applicabili anche a Oracle o PostgreSQL e un momentaneo lieto fine.

IoT, sviluppo su moduli Cinterion

Sotto la spinta di un crescente sviluppo della IoT, in un mondo web e smartphone oriented rispunta la tecnologia j2me e embedded jdk. Vedremo come e dove si sfrutta questa tecnologia.

Spesso l’”internet delle cose” richiede interfacce verso sensori di vario tipo tra i quali accelerometri, sensori di temperatura e GPS spesso collegati via UART e i2c. Scopriremo cosa sono, come usare questi bus di dati e come dialogare con i vari sensori. Il tutto dall’interno del modulo Cinterion EGS5-x.

I sistemi embedded sono solitamente ambienti in cui scarseggia la memoria e la capacità di calcolo, esploreremo come sfruttarli al meglio e come evitare errori di architettura del software per questo tipo di hardware.

Non sei stufo di scaricare jQuery? (“Tool di front-end in webapp Java”)

Uno sviluppatore Java è normalmente concentrato soprattutto sullo sviluppo in Java, con i relativi tool e ambienti di sviluppo. La parte di ambiente di sviluppo front-end è quasi sempre trascurata, demandata ad altri, ed estranea al normale processo di sviluppo di una webapp Java. Deve essere per forza così?

Innovazione e contaminazione digitale Industry 4.0


La partecipazione è, come sempre, libera e gratuita.

Se usi GPG potresti portare la fingerprint della tua chiave su un foglietto e chiedere se qualcuno è interessato a firmarti la chiave.

Al termine del meeting andremo tutti assieme a mangiare al ristorante Wok Sushi :-P

    Generically, any database management system (DBMS) that can respond to queries from client machines formatted in the SQL language. When capitalized, the term generally refers to either of two database management products from Sybase and Microsoft. Both companies offer client-server DBMS products called SQL Server.
