Basic error signaling in REST API are usually driven by HTTP status codes (eventually also using the HTTP reason field, even if its purpose is tied to CORS implementation). This is generally handled causing an exception in http client libraries (like MARS Client Library, Indy, REST Client library and others). However, it is not uncommon […]
I am happy to revive my blog to share some (good) news! After a quite long period I focused on “less public” work (as developer and consultant), I am trying to get back to developer conferences. Even if logistics and time availability are quite a challenge, for a number of reasons, I strongly believe to […]
Workshop in Denmark On September 13th and 14th I had the pleasure to be the speaker at DAPUG workshop in Denmark.

I’ve been happy to had a chance to share some time with other developers from different countries (including Denmark, Finland […]
Giovedì 16 Dicembre 2021ho tenuto un webinar per OSItalia. Il tema era lo sviluppo di un (semplice) client mobile per i servizi REST relativi alla fatturazione elettronica forniti da OSItalia stessa. L’intervento seguiva un altro webinar tenuto da David Lastrucci relativo alle API sottostanti. Ho deciso di usare il mio framework FMXER (disponibile gratuitamente su […]
Yesterday a customer asked me about customizing the FMX dropdown in order to make it consistent with the rest of UI. Specifically, we were trying to change the background of the dropdown list to a semitransparent color. Even if this sounded trivial to me at first, it turned out to be a little tricky, hence […]
Since legal invoicing became mandatory for every company in Italy (2019) many Italian people had to start handling XML files containing invoice data. Many viewers are already available to browse invoice files yet still the activity may become very time-consuming and far from trivial for the regular user. In particular, some people (accountants or managers) […]
Dall’introduzione dell’obbligo di fatturazione elettronica, introdotto per tutti in Italia dal 2019, molti di noi, a vario titolo, si sono trovati a dover maneggiare file XML delle fatture, attive o passive. Nonostante siano molti i visualizzatori disponibili (online e offline), ancora oggi maneggiare questi file può essere tutt’altro che immediato. Soprattutto chi (magari i commercialisti […]
I’ve just pushed a few commits to MARS (https://github.com/andrea-magni/MARS) repository and there is a new feature in the library now. Nowadays, for a number of different reasons, you may find yourself trying to keep your endpoint’s URLs as short as possible. It is quite usual to see urls like https://youtu.be/[id], a shorter version of https://www.youtube.com/watch?v=[id]. […]

One of MARS users (Kostas, thank you for the constant feedback on MARS) asked how to enable SSL through Indy built-in server (link). I personally tend to setup a reverse proxy (using Apache, nginx or Microsoft IIS) and let the webserver to take care of low level aspects such as SSL, compression, caching and load […]
