Arduino is a great hardware for a lot of reason: easy to use, difficulto to break, it is a very solid 5-Volt board.
But it a way too much and it has a very limited amount of RAM. So I started exploring other more “different” solutions. I need an economy chip with some RAM on it. After some research, I stumpled upon a lot of so-called Arduino alternative…

Oracle SQL Developer is full of nice feature, damned by a overwhelming options pane, like the one I will describe to you right now.
Even if Oracle databases (<12) does not support auto increment, you can easily ask to your sql data modeler to generate for you a sequence and a trigger in a automatic way.

Oracle SQL Developer is full of nice feature, damned by a overwhelming options pane, like the one I will describe to you right now.
I will show here a very fast way of comparing different database and auto-generate migration script.
- Reverse engineer the source database using Oracle Data Modeler
- Now select the right arrow shown below:
- Select the destination datasource (more here) when asked.
- The compare pane will enable you to compare the databases.
But the default options will also use schema name to detect different object, so you will not get what you want in every scenario.
In 50% of my daily job, schema are different, so you must select the options below to fix it:
Select "Options" and then "Compare options". Then de-select "Use schema property" like suggested below:
- Push the "Sync new object". Then push the "DLL Preview" button and inspect the generated database.
- Bonus: by default the tool will not include tables to drop. Inspect the two pane ad check the table you want to drop in the left pane.
- Refrain launching the script without proper testing. You are migrating your valuable data.

I have just read what Apple shown at the WWDC 2016.
In the 1985 Windows 1.0 was born. In a snap, the IBM compatible system evolved, and the competitive advantage of the Macintosh dried up and disappeared.
IBM PC was cheaper and way more open.
Like in the 1985, now in the 2016 the iPhone revolution has come to an end. After the Retina Display introduction, no real new feature was introduced. The apple Watch was beaten by competition.
Two years passed with no true innovation (i.e. Apple Watch is not a revolution).
The last MusicApp removed the beautiful cover navigation, and try to sell you the apple music rent service all the time, instead of let me play the music I have already bought.
MacOSX is the oldest one nowadays.
Historically Apple system are very closed. The reason is simple: when you go to your shareholders and ask for money, you can show you have a competitive advantage, a strong set of feature no one can take apart from you. But Apple lost this war in 1985, when the high pricey Macs cannot compete with open IBMs clones.
To be fair, IBM could open to clone market because its business was on high-end server, and Microsoft alliance will help to sell more IBM PCs.

I have just read this insightful statement on this blog article about congitive load in Javascript
jQuery is undoubtedly useful when dealing with browser quirks, but once an application grows over a few thousand lines of code, unstructured jQuery code simply becomes too difficult to maintain, and you start needing the discipline of a framework to organize code. But when you're at tens of thousands of lines of code, you start to run out of entity types to CRUD, and your application growth starts to build on top of existing concepts. This is when you need the mental shift from being a library consumer to being a reusable component author,
This clever guy is the creator of Mithril, a very small, well crafted javascript library a friend of mine pointed to (via github…):

After my two children grow a little, I have some spare time to play with RaspberryPi. I have bought a Raspberry Pi 2 Model B, a very neat and compact machine with 1GB of RAM, and a quad-core ARM chip on it.
I was looking for an easy-to-carry unix box, and I was wrong: raspberry pi can be a lot more than that.

I am a very happy owner of a RaspberryPi Model B 2, a quad core ARMv7 computation unit for a price between 45 and 35 €.
If you plug only a network cable it can be powered by a USB port of your router (!avoid putting on it other USB stuff, because the energy drain can be too much).
RaspberryPI is a perfect all-time-running machine, just follow this smart guide…

Working in a big company, my work laptop came with MS-Windows7 Enterprise installed. But as you imagine, Unix is my preferred desktop environment. So let’s how to configure a perfect Debian Linux for a old wolf consultant like me. You will be able to install commercial software mubmo jumbo like Oracle Express and IBM Websphere in a snap, and have a 64 rock solid system, easy to bring in a USB stick if you like.
