A tutti gli assidui utilizzatori delle macchine per il pane, suggeriamo il seguente lievito madre, che dà ottimi risultati.

Inoltre contrariamente a quanto suggerito nelle istruzioni, se usate una macchina per il pane è sufficiente aumentare le dosi standard suggerite dal manuale di istruzione delle macchine di appena 0,5 cucchiani, e servirsi negli impasti di farina manitoba (bastano 100g) per ottenere ottimi risultati.Altri consigli li trovate qui.

Qualche mese fa avevo sviluppato una applicazione IoT per misurare la temperatura e spedire i dati ad una coda mqtt. Poi c’era uns server che collezionava i dati. Totale: tre server, con tre punti di fallimento ma architettura molto “cool”

In effetti però la potenza dei moderni chip embedded è tale che è possibile implementare una soluzione completamente asincrona “alla Erlang”. Con meno di 8 euro, potete procuravi il chip esp8266 su Amazon

Ho ricevuto come gradito regalo il Super NES Classic in versione “mini” che potete trovare su Amazon ad un prezzo intorno ai 70 € con 21 giochi precaricati dal sapore Retrò anni 90.

Come vedremo è possibile aggiungere altri giochi (anche per altre console!), effettuando dei piccoli hack…

After a bunch of years, I am happy to announce StereoSID 2.0.6 is here to stay. It spots a new sid_player example and some optimization on the I2C implementation. https://github.com/daitangio/sid-arduino-lib

From an internal email of a very very big corporate company

Incident Background: BIGPROJECT has been unavailable since APAC SOD due to a data refresh activity being wrongly triggered in from UAT to Production environments.

Business Impact

1. BIGPROJECT is unavailable for all users in the bank
2. BIGPROJECT2 platform which sits on BIGPROJECT is unavailable this includes the Click-to-chat serviceCurrent Status
3. Initial attempt of flashback Database to restore from the last good restore point failed due to errors due to absence of flashback logs– this was a quicker option, but now ruled out.

• Currently going ahead with full restoration in the Primary database – this activity is tentatively supposed to take 8-9 hours (in place of 6 hours earlier mentioned)

After 5 hours in another email they dare to say:

After some trial and error, I decided to switch to a new syntax highlighter library, mostly because the old one stopped working. I am very satisfied with Crayon because it is backward compatible with  the previous plugin based on SyntaxHighlighter3 and offer also a nice in-line editor.

Sometimes I need a very very fast start on emacs. If you have the same need, put this in your init.el and live happy:

(cua-mode)
(setq select-active-region nil)
(setq mouse-drag-copy-region t)
(global-set-key [mouse-2] 'mouse-yank-at-click)

Assembly: the only way

In principle there was only one: assembly machine language. Hardware and software engineer was a one-role.

The guy who was able to project a chip, was the one who was able to program it.

Then Fortan (1957), the first high level language compiler was created.
