Sometimes in University I found bold young guy saying something like:

I will reimplement this in machine language because is faster

I will reimplement this xyz C function by my own

My program crash, I think there is a bug in HP UNIX socket implementation

I will ge rid of this Java Garbage Collector because it is too slow. I will reimplement all the code in my C++ routine.

Belive me: your code is doomed. A full list of guys have already done your same code, found a million bugs and corrected it in the tool you want to replace because they are shitty slow, to your eyes.

I feel your pain because I made your same mistake. Keep reading.

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.

1. Reverse engineer the source database using Oracle Data Modeler
2. Now select the right arrow  shown below:
3. Select the destination datasource (more here) when asked.
4. 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:
5. Push the "Sync new object". Then push the "DLL Preview" button and inspect the generated database.
6. 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.
7. Refrain launching the script without proper testing. You are migrating your valuable data.

Pandoc is an universal document converter to convert Markdown, Org-Mode, Html, Word documents from one markup format into another  After using different tools, (including GNU info and SGML). I find out pandoc vert handy.

The BBC Micro bit an ARM-based embedded system designed by the BBC for use in computer education in the UK. The device has been given away free [...] [to every 11 years old pupil] in the UK, and is also available for purchase by anyone.

This is the wikipedia definition.

In ambito Open source vi sono innumerevoli licenze disponibili. Quali sono le loro differenze salienti? Come orientarsi? In questo breve articolo diamo una serie di indicazioni e spunti di riflessione.

To increase performance and SD life of your raspberry PI 2/3, you can follow my first article on this subject.

You can easily increase even more the SD life if you can trade a bit of RAM.

The key idea is to take advantage of tmpfs, which can be resized on the fly too.

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.

If the WWDC2016 breaking news is a new file system, it is a very poor gift. I am writing this note on a Windows 10 PC. It is not a shining operating system it freeze a bit and has still a very ugly backup engine, but MacOSX is not the “most advanced operating system” anymore, like it used be in 2000.

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.

After my first child reached 5 years old, I decided it was time to start my Lego Technic Revenge, together with KyloRen Star Wars lego-puppy (eh eh).

It is very difficult to find out a good set to play with gears and so on. The big Lego Technic toys like cars and so on are sold without nice pieces to link with “normal bricks” (see below the red one).

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…):
