Character encoding is a very bad beast when you write code, but UTF-8 will save us.
Belive me: You will love the Big Brother and the UTF-8.

It was designed for backward compatibility with ASCII and to avoid the complications of endianness and byte order marks in UTF-16 and UTF-32.

I admit it. I suffered from an “algebra narcoleptic syndrome” during my relational database lessons at University (1996 circa).
Ok it is a fake. But it seems so real on these days.
I was unable to avoid sleeping. I learned to love SQL after some years and now I think SQL is the most powerful, direct and useful stuff you can learn.

At Dropbox, Kafka clusters are managed by the Jetstream team, whose primary responsibility is to provide high quality Kafka services. Understanding Kafka’s throughput limit in Dropbox infrastructure is crucial in making proper provisioning decision for different use cases, and this has been an important goal for the team. Recently, we created an automated testing platform to achieve this objective. In this post, we would like to share our method and findings.

isync: free IMAP and MailDir mailbox synchronizerisync is a command line application which synchronizes mailboxes; currently Maildir and IMAP4 mailboxes are supported. New messages, message deletions and flag changes can be propagated both ways. isync is suitable for use in IMAP-disconnected mode.Synchronization is based on unique message identifiers (UIDs), so no identification conflicts can occur (as opposed to some other mail synchronizers).Synchronization state is kept in one local text file per mailbox pair; multiple replicas of a mailbox can be maintained.isync is free software in the sense of the GNU GPL v2.

The department of defense, has published a nice document to “detect” agile bullshit. The document is called DIB_DETECTING_AGILE_BS_2018.10.05 and was published on October 2018.
We saved a copy on our site, because we think it is very very interesting…

Alfine mio figlio di otto anni mi ha fatto una domanda su Salvini. Sarà che è sempre in TV insieme a Di Maio, che non si parla d'altro o che il populismo è accessibile alle nuove generazioni.
In TV passano immagini di gente che muore in mare. Riconosco che l'immigrazione non gestita possa diventare un problema in futuro, ora non è così grave (perlomeno non dove vivo io). Per fare un esempio ho assunto 4 tate in otto anni, facendo una quarantina di colloqui e solo in un paio di casi c'erano delle canidate "italiane", ed in entrmabi i casi hanno avanzato proposte discutibili. C'è sicuramente una certa parte del paese (la mafia per esempio) che fa i soldi sull'emergenza continua che si attualizza nei centri di asilo, c'è il racket degli accattoni davanti ad ogni bar che sicuramente sfrutta i poveracci senza lavoro, ecc.

I am studying Apache Kafka (a "distributed streaming platform") and I stumbled upon this conclusion: the "disk read fear" a lot of projects have in the past, is a fake.

A lot of distributed database started tutorial with the statement "disk read are slow, write are fast" which is true to some extent, and accounted for de-normalizing data and memory caches.

Nel 1492 Colobo scoprì l'America scommettendo sul fatto che la terra fosse tonda. In realtà c'erano parecchie prove indirette, ma nessuno lo aveva ancora dimostrato, e soprattutto i rischi di andare per mare erano altissimi. Ora girano per internet teorie complottiste che

C'è una riflessione profonda fatta da Roberto Toninello sul Post.it
L'articolo merita di essere letto ma il succo è questo: il governo festeggia l'abolizione di vitalizi che portano un risparmio di quaranta milioni di euro, l’anno. Peccato che queste sono noccioline in confronto a quanti miliardi vengono "trasferiti", per ogni aumento dello spread, dai poveri ai ricchi speculatori. Toninello lo chiama Robin Hood alla rovescia. In pratica in termini economici vale molto di più una cavolata detta da Di Maio/Salvini/Conte/Tria che fa impennare lo spread rispetto ad una faticosa legge approvata in parlamento, su cui peraltro sono d'accordo.

On this Christmas, a lot of us will pay more then $1000 for a new iPhone XY or for a similar Samsung one (twice the price of a netbook) and you will have in your hand a quite powerful machine: for instance iPhone used as Theorem Prover is faster then an Intel Workstation (!)

Sometimes your windows' HyperV Hypervisor will refuse to start.
The problem is tricky because the services seems started if you check them. Also the installation is successful, virtualization is enabled and so on. So what is wrong?
