DBeaver

Hi all

Today I want speak about one of the best DB Client tool in the market : DBeaver .

Why it's so good : 

1) It's an open source project, here github page. 

2) It's multi DB, instead to have many DB client, one for every DB. 

3) It's fast and light.

Before to discover it, I'm using for Oracle DB, ToaD and SQLDeveloper, both of them don't satisfy any of points above.

Actually I am using it for Oracle, Sqlite, Mysql and PostgreSQL.  

Actually, when I write this post, last version is 24.0.0, new versions are released with a great frequency and behind it there are a large community.   

So download it and enjoy.

Stay tuned. 

Devtranet

 Hi all

Today I want to speak about a a new place for developers to connect, share projects, blog, and find collaborators called Devtranet.

Really It's a great site and a space for developers to share ideas, projects and stuffs.

It's was created and co-founded by Ibrahim Salami a very young developer.

Actually it's a beta site, but I guess will be a success.

Stay tuned.

Generate Random Data for Testing

Hi all

During my last work project, I need to create a large amount of data for test.

Searching on internet a tool to create random testing data I found some tools, in particular one over all catch my attention.

It's name is Mockaroo, an online tools permits to create a large number of output format (JSON, SQL, CSV, ...).

Interface is very intuitive and using formulas and predefined datas it's possible create a very large set of random data.

Unfortunately in free version is possible only create a maximum of  1000 records for output, anyway more than enough for my test.

I recommend to try this tool.

Stay tuned.

COVID or No COVID

Covid or no covid this is the problem. 

A strange year is going to finish. From March I am in SmartWorking, my Argentinean project also is going to finish, after 16 years probably this his the last year.

An important chapter of my working life will be close.

Reasons ? Probably first reason is COVID that caused an important economic problem in all fields. The second reason is a decline in telecommunications revenues, specially voice and sms wholesale business.

But here is the first responsible, Mr. Covid : 

A little virus with a great power. It has generated fear, terror, anxiety but over all it has changed our life style in all areas : work, school, human relation, shopping, holidays, etc....

I don't know if it is true or not, if it exists or not, there are many blogs and conspiracies about it, I don't care about them.

But one thing is sure "Covid has given a boost to technological innovation" improved smart working where possible, a new way to work, to interact and to live.

Stay tuned.

 

A failure announced

Hi all

Today I want speak about new Nintendo Console. After the failure of the sale of the Wii U, Nintendo try again with another one.
Like Wii U, this console permits two use, home and portable.

Nintendo Switch is the name of this console, I think that this name is due to this double use. In portable use, it is like a tablet with a screen of 6.2 inches and a resolution of 720p. At the screen tablet you can add the two controls used in home use.

In this link there is a good review.

In my opinion this new console will be a sure failure for these six reasons :

1) This console isn't backward compatible with Wii U and Nintendo DS.
2) This double nature (portable and home) was a failure in Wii U.
3) The design is retro and the colors aren't attractive (but this is my personal opinion) grey is horrible color.
4) The price of 329 Euro it's too expensive in comparison with PS4 and XBOX.
5) Nothing innovative.
6) 3 March is a wrong date of announcement and sale, just after Christmas time.


Stay tuned.

The 2017's second post

Hi All

The second post of this 2017. Many changes will came : a new USA president, many changes in my work and a little hope to change mine.

But first all, this new USA President, TRUMP, what about him? The world is really worried. Many people think that he is like a new Berlusconi but with a large audience and power. Really I haven't an opinion about him, Obama was one of the biggest disappointments in the history. Really I think that Trump will be another anonymous president a little bit more folkloric nothing more. Probably he will not end its mandate if he does something against the interests of lobbies or somethings strange, someone speaks about not much more two years of presidency, we will see.

Another item of this new year, is my actually work, many changes will come and not all goods. Actually Vivendi controls TIM but some rumors speak about a possible sale to ORANGE (ex Telecom France). If it's true another big changes will come. We will wait for it.

My new job, I hope and pray about this. Finally I hope that 2017 will be the year of my personal change to improve my work life and my life in general.

So we go into this new year.

Stay tuned.

My first mobile app in 2016

Hi all

This year i want do my first app on android, one of my year's objectives.
This is the year :-)
An app on android, uhmmm ...., ok but the first question is "What kind of app ?", a game, an educational app, an app for useful use, ....
Uhmmm ... ok a game, i have many ideas about it.
Second answer "A 3D game or a 2D game?", ok a 2D game more simple.
Third ansert "What library i must use to do it?".

Below there are some of the most used 2D library :

Commercial C++ frameworks:

• Unity3D: very good (available on Android, iOS, Web, Windows, OS X) [Game: Rocket Bunnies]
• Unreal Engine (commercial): the best engine but not for beginners [Game: Dungeon Defenders]

Open Source C++ frameworks:

• Ogre3D: the best open source 3d engine but it is a large framework
• Irrlicht: good performance, light framework [Game: Moblox]
• Linderdaum Engine: open source for Windows and Android
• Cocos2d-x: open source cross platform

Java Open Source Frameworks:

• LibGDX : Open Source, Very Popular, Supports multiple platforms, Support for Tiled, Box2D and other, Good Documentation
• AndEngine (Open Source): good performance. For documentation, look examples and read source code; but it is the Free library to begin a game project [Game: Drop Block]
• cocos2d for Android: Garbage Collector problem
• SDL is not a good idea because it is designed for framebuffer access.
• rokon: good performance and designed for mobile but project seems dead.

Physics Engine:

• box2d (OpenSource): fast and easy
• jbox2d (OpenSource): so slow on Java that I made a JNI wrapper with SWIG to use native box2d (AndEngine does the same)
• chipmunk (OpenSource): fast but I prefer box2d
• bullet (OpenSource): excellent 3D engine

After a "deep" analysis my choice was "libGDX". "Why this library ?", for these three reasons :

1. Because it is in JAVA (I know this language)
2. Because it is multiplatform 
3. Because it has a good documentation 

Actually i am doing a course on "UDACITY" learning site, named "2D Game Development with LibGDX". I hope that it helps me :-).

Stay tuned.

Good things and Bad things

Hi all

There are good periods and bad periods in a life of a human. Many periods are worst than others and others are better than others. Life is just it.

This period in my life is a bad period, but it is not useful crying or complaining.
Yesterday i was thinking that there are many good things in my life and when i am focusing about them, bad things not appeared so bad.

So, the answer at bad moments is simple, you must focus on good things.

Take a sheet, divide it in two parts, in the left part, write good things and in the right part write bad things.

Probably good things are more than of the bad things as for me, or not. But the secret to change your life is thinking on the left side's things in the sheet. If you think too much time in right side, you will forget left side and so you will forget the good things that are in your life.

It is like the cherokee legend about two wolves. You only can decide what things are really important in your life.

Stay tuned.

My first online Course

Hi all

I am proud to announce that i have finished my first course in Coursera Site.

This year it was one of my goals.

The course was simple, a course for beginner programmer in python, "Programming for Everybody" of University of Michigan with 10 weeks of study.

I choose it for two reasons :

• My bad english level
• My basic knowledge of Python

The curse's instructor was Charles Severance really very nice and competent instructor.

Really understanding of English was not a problem and coursera allows you to slow down to listen the lessons.

I recommend this course to all those who want to learn English and the basics of programming, Python is a great language to learn to program.

Stay tuned.

eLEARNING part II

Hi all

Today i want extend my post eLearning posted in 2014.

Actually i am doing three courses, two in COURSERA about python and one, about Android, in another eLeaning site not listed in my previous post named EDX.

In EDX there are many and various courses about different matters of the most important university of the world.
I recommend you take a look at this site.

Good study.

Stay tuned.

eLEARNING

Hi all

Today i want speak about education and eLearning websites.
Personally I am using COURSERA, in this site you can find many courses about a lot of arguments from Literature to Engineering.

Actually if you want study, internet offers many possibilities, there are no excuses. Only you have to choose the course and follow it.

During the course selection it's very important put the focus on three questions :

• Why do i want learn it? 
• What do i know about this matter?
• What do i expect from a course ?

In other words where i start and where i want arrive. Learn is simply a path from an A point to a B.

Another important factor is "perseverance" if you don't have it never you can terminate a course, you have to spend part of your time to study continuously day by day, week by week.

Use a eLearning site it's different to study in a real classroom and it needs more discipline, concentration and good capability of autonomy, Instead you can organize better your lessons in according of own learning ability.

There are many eLearning sites, for me the best alternatives to COURSERA are :

• CODECADEMY
• KHANACADEMY
• UDEMY 

The last one it's one of the best about computer science and programming languages

Stay tuned.

Easter egg

Hi all

Today i want speak about "Easter egg".
In Information Technology, "Easter eggs are secret responses that occur in response to an undocumented set of commands." how is correct defined in Wikipedia.

Basically an "Easter egg" is  a programmer's signature, a way to be recognized.

Here some internet examples :

You Tube : Try to write "do the harlem shake" in the search bar and find it.
http://theoatmeal.com/ : Try to see source html code
http://www.entercomputers.com/ : Visit this website and type 'penguin' on the hompage. Note animated penguin. Then wait for something else to happen.
http://www.miniusa.com : Type ‘reverse’ in the search field and then hold down Shift and click on the gear lever.

There are many internet sites about, for example here.
