Sono convinto che parlare delle prodezze dell’attuale presidente degli Stati Uniti possa solo amplificare la pubblicitá delle sue idee strampalate. Restano sul tappeto i fatti peró, e su questi un pó di riflessioni vanno fatte.

In questi ultimi cinque giorni, abbiamo assisito al balletto dazi si, dazi sospesi, dazi forse.

Ho iniziato a scrivere questo articolo un mese fa, cercando di raccogliere mentalmente l’enorme elenco di iniziative strampalate portate avanti da Trump. Non è bastato attendere, per sperare che la polvere delle sue azioni si depositasse! Proviamo a fare qualche riflessione in ogni caso, perché i fatti hanno tale portata da non poter essere ignorati.

We already discussed about Queue management solutions in the past, and I am always happy to write about it. Queue managers are not easy to implement, and there is a reson if IBM MQ Series is still a successful product. Some month ago, a big bank customer asked me to provide a small queue implementation to increase asynchronous internal processing of our payment solution.

The project had very strong contraints: I could not use existing queue system because they were not yet available, and I need to be able to provide microservice parallelism in a cloud-environent.

I have very little time to provide a solid solution, and re-inventing the wheel was not an option. Performance was important, but we plan to have a managable numbers of transactions per seconds, far behind modern cloud database capacity.

Challenge accepted.

HP started designing handhelded calculators from 1968 until the end of ‘80. I buyed an HP-42S around 1993 but it has been designed near 1986.

Here I want to focus on the chip design of the 10C series, a compact set of calculator with programming abilities but with full numeric display. The HP-15C was introduced in 1982, in the full 8bit computer era, the same year of the C/64. Later model will feature a more mature “Saturn” processor. I will describe here this chip at the best of my abilities, because it sheds a light on how custom architecture was done around end of 1979.

Di solito non amo fare recensioni sulle serie che vedo su Netflix, perché i gusti sono gusti e non bisognerebbe discurterne, ma in questo caso, faccio volentieri un’eccezione. Vorrei consigliarvi una serie da vedere ed una serie da evitare, rispettivamente Running Point e ZeroDay. Eviteró spolier per quanto possibile.
