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…

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.

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?

After some years in IoT, I tried a bunch of different platform like esp8266 but Arduino remains a must.
Simple reason to choose it for your first (or second :) IoT project:
- Arduino works at 5V and can accept as input voltage 7-12V, but with limit up to 20V (avoid it! :).
This mean you can use a wide range of power supply (4 AA Batteries, 12V transformer from your dead router and so on) - Arduino board provides a 5V regulated output and a 3.3V too for working with a wide range of sensors.
- You got 6 Analog2Digital pins (the A0...A5 pins) with a 0..1024 value resolution. In comparison, esp8266 has only one pin with less resolution.
- It is completly open source, so you can find easily cheap clones like this one at less then 10 euros.
- The ATmega328P chip inside Arduino provide I2C and SPI communication which means you can easily work with other chip.
You can even program an Arduino to be an I2C client to other Arduinos making a small set of complex circuits.
For instance, the C/64 SID chip emulator can be compiled to act like a I2C slave and another Arduino can program it like...a SID chip - Did I talk about the real time operating system, written by an italian guy?.... I was able to use it to build a small "Egg box Lamp".
- Arduino works at 5V and can accept as input voltage 7-12V, but with limit up to 20V (avoid it! :).
