Run .jar file on Linux

Hi everyone,

Today, I am bringing to you a very nice thing, if you have written java code on windows, exported it as a .jar file and used it on Windows but was unable to do this on linux though you have JDK installed on linux, then this is the right place for you !!

To do this surely you must have a correct and runnable java code with a main class.

Steps:
======

If you are using netbeans right click on the project and then click clean and build, on eclipse right click on the project and then choose export and choose as runnnable jar file.

This will create a .jar file in your project folder (for netbeans inside the dist folder).

You will open your nice terminal and start by creating a "launcher" which is a shell script that you create so that it can run your .jar file.

In this example I made a simple watch and the jar file is named SimpleWatch.jar, ok?


you will type:

cd /usr/local/bin

then

gksudo gedit SimpleWatchLauncher.sh

the last command will open the Text editor you copy and paste this

#! /bin/bash
cd /home/khaled/NetBeansProjects/SimpleWatch/dist
java -jar /home/khaled/NetBeansProjects/SimpleWatch/dist/SimpleWatch.jar

Of course you will replace "/home/khaled/NetBeansProjects/SimpleWatch/dist" with the path of the directory that contains your .jar file

Save and exit the Text editor






Type this in the terminal (Make sure you are in /usr/local/bin)

sudo chmod +x /usr/local/bin/SimpleWatchLauncher.sh

That's it you are done !!!


now open your terminal and type:

cd /usr/local/bin/

Click enter
then type

SimpleWatchLauncher.sh

Your application will Run isA and you will now that Java is really platform independent :D

فرانكو لعربي

عاملين إيه ؟
البوست ده أصلا أنا كاتبه كله فرانكو مش كاتب ولا كلمة فيه بالحروف العربي اللي على الكيبورد !! إزاي بقى ده عن طريق برنامج جامد جدا مايكروسوفت نزلته اسمه Maren البرنامج ده تقدر تخليه يحول الكلام الفرانكو إلى عربي وإنت بتكتب والصراحة البرنامج جامد جدا و التوقع بتاعه رائع جدا لكن في حاجة مهمة كنت عاوز أقولها إن على اد ماالبرنامج ده و ال برامج اللي زيه بتخلينا نكتب عربي أكتر على الانترنت على اد ماهي يخلينا نستغنى تماما عن الحروف العربي وتقريبا ننساها لاننا كده بجد عمرنا ماهانسخدم الزراير العربي على الكيبورد لاننا ياما هانكتب فرانكو أصلا أو هانكتب فرانكو مترجم عربي

عموما البرنامج جامد جدا وأكيد هستخدموا بالذات في بوستس على البلوج هنا في اللابل الجديد اللي اسمه بالعربي
الحاجة برده الجديدة إن مايكروسوفت نزلت البرنامج ده ببلاش يمكن عشان عارفة إن قليل قوي من المستخدمين العرب ممكن يدفعوا فلوس مقابل سفتوار بس ياريت مايكروسوفت تنزل نسخ تشتغل على انظمة تانية غير الويندوز زي لينكس وأبونتيو وكمان ماك .... يا رب



ممكن تنزل البرنامج من اللينك ده

واتفرج على الفيديو اللذيذ ده كمان عن البرنامج


سلام

Clean you Vista

Hi everyone,

If you are using Windows Vista like me, you may have noticed that the free space on your C drive where you installed Windows decreases even if you install no new software on it. This is caused by many things, the most important ones are temporary internet files which are files stored on your hard to enable you surf the internet faster, Temp folder which may be up to five GB which saves configurations about applications you ran on your computer, the hibernate files which enables your computer to hibernate.

You can clean them up and free space so you can speed up your system by using the clean up disk tool
Start -> Accessories -> System tools -> Disk Clean Up

Any way if you really want to clean every thing and get more space, I recommend a tool called CCleaner (Crap Cleaner), it just Free 3.8 MBytes and still it cleans your folders safely and fast, it cleaned about 9 GB from my C Drive !!!

Go to CCleaner

لون روحى

أقف أمامها , أمرر أصابعى على إفريزها الذهبى , أتحسس حروف اسمى التى نقشت بعناية . اقترب قليلا ً لأشتم رائحة الألوان و القماش , ما زالت الرائحة كما كانت عندما أدركتها أول مرة .

"أسف و لكنى لا استطيع منع نفسى" هكذا همست إلى اللوحة و أنا أعلم أنها ستتفهمنى . نظرت إلى الفرشاة الموضوعة بحرص على الترابيزة المجاورة ... بدأت التقط علب الألوان و انزع عنها ذلك الغلاف الشفاف و عينى تمتلىء بالدموع , صوت بداخلى يتوسلنى لماذا تريد أن تعبث بها ؟ لقد تركت القدر يرسمها لك طوال السنين الماضية كان يصلحها هو كلما أفسدها . كنت دائما ً تسخر من الأخرين إذا رأيتهم يغيرون لوحاتهم بإيديهم و تندهش منهم و هم يزيلون ما أضافوه للتو , تتمزق لوحاتهم يرقعونها بجلودهم , يحاولون فى يأس استعادة عذريتها التى أضاعوها منذ سنين.

ظلت لوحتى هى الأكمل و الأجمل , كلما يسألنى أحدهم كيف استطعت أن تحافظ عليها أجيب بأنى فى الأساس لم ألمسها قط , ينظر إلى باستغراب يتمتم ببعض كلمات " أحمق ... مغفل ... مجنون ... " , لكنى لم أهتم أبدا ًبما يقولون , و ليس كلامهم هو الذى يحرك يدى الأن و هى تخلط الألوان استعدادا ً لأن ارسم على لوحتى لأول مرة .

- حلوة أوى اللوحة , بس أنت فين ؟
- ايه !! أنا فين ؟؟!
- أه أنت فين ؟؟
أخذت أبحث بين هذه الوجوه المنتشرة على سطح اللوحة و لكنى لم أجد نفسى .
- مششش عارف تلاقينى هنا و لا هناك بس مش باين , ما أنا قولتيلك أنا عمرى ما جيت جنبها !!


لم ترد و لكنى رأيت فى عينيها ابتسامتى البلهاء , تردد نظرها بينى و بين اللوحة , شعرت بخيبة أمل أطلقتها فى تنهيدة حزينة حارة مازالت تلهب جبينى , رحلت و لم تأت ثانية .
شعرت برعشة اسقطت الفرشاة من يدى , انحنيت لالتقطها فاختلطت الألوان فقد كل لون وجوده و ذاب فى وجود الألوان الأخرى , لا يهم سارسم نفسى الأن بأى لون أيا ً كان , و لكن أين اضع نفسى ؟ فى المنتصف سأكون قريبا ً من كل شى ء , و لكنها فى طرف اللوحة " ارسم نفسك بجوارها إنك تفعل كل هذا من أجلها " .

حسنا ً, انا الأن فى لوحتى بالقرب منها , لا شىء تغير ما زلت لا أراها و ما زالت حياتى كما هى , لا فرق إلا هذا اللون الغريب الذى رسمت به نفسى , إنه يسيطر على اللوحة , طرد كل الألوان على الإطار الذهبى , لن أزيله و ليحدث ما يحدث , لن أزيله مع أنه دهس جسدها الجميل و ألقى به على الأرض , لن أزيله مع أنه هو الذى دمر حياتى , كيف أزيله و هو حياتى و ليس اللوحة فلتذهب اللوحة للجحيم و يبقى لون روحى .

3 in 1 xampp = PHP + MySQL + Apache

Hi every one,
Well I was assigned to build a web site that uses php and MySQL to register users
who will be students and professors and show them courses and other options.
Any way, I needed to setup all of php, MySQL and Apache (as a server). I looked up on the internet and it wasn't that easy. Yes you will download the three of them easily as they are all free, but it will need a lot of work in order to integrate them with each other and run them.
In order to get rid of all of these nasty stuff, all you have to do is to download and install a package called xampp whih includes all the above tools and it is very easy to install and use as well.

Here are the steps to have your own server where you can build a database and PHP files:

1 - You have to download xampp, it is open source so you will find the suitable version for your machine. just go to xampp home page

2 - Choose the version that suits your operating system - xampp is avaliable for Windows, Linux, MAC and Solaris -

3 - You can download the installer or the zip or the exe. I recommend the installer, it is easy and safe, also it is only 35 MB.




4 - Run the installation normally, it would be better not to install it in C because you may get bothered for security options on Vista.

5 - After the installation is done, go to the folder where you installed xampp, run the xammp controller



6 - You should have a window like this:



7 - If the Apache server is not runing, just click on start, do the same for mysql in case you need it.



You will find it on your tool bar





8 - Now it is all set for us to run the server, just go to your internet browser
and tyoe this in the address bar:

http://localhost/xampp/index.php

If you have the same as this then every thing is set you can build your own php NOW.




9 - Now let's build our site:

- Make a new folder that should contain all the pages, we will name it MyWeb

You have to make this new folder as a subfolder in the folder named htdocs you can find this folder in the folder where you installed xampp.



- download this file called firsPage.php

Put firstPage.php in the folder MyWeb that we created at the previous step.

10 - Write this url in your address bar

http://localhost/MyWeb/firstPage.php

and click Enter

Yes you just did it !!



If you have any comments or questions, don't hesitate

Saving Energy

Hi everyone,
While I was surfing on the internet, I found a very interesting site, it calls you to join them on their cause for saving energy.

You must have heard people talking about this matter many times before, but I doubt that it ever caught your interest or made you really change your habits or adapt new habits that would save energy.

This web site is REALLY different, it is very exciting and brings you to the core of the problem, it shows you how you by changing your habits and adapting new ones would change things in numbers. For instance, it shows you how much money you would save if you go to your work on a bike three days a week, it also tells you how much the equivalent energy saved by you can do in other fields (like charging your laptop or providing a hospital with energy).

The nicest thing in the site is the game, yes you can play a game where you have a city in 2015 and you have to provide it with enough energy, you get to choose between all sources: nuclear, hydro, natural gas, etc. Anyway, you have to watch out for three meters: Economic, Environmental and Security, you have to balance the three meters to get the highest score, it is really nice and will teach you something as well.

Go to the site here
To play the game choose energy ville.
If you want to see how much you can save here

47 million years old OMG !!

Hi everyone,
You must have heard of the evolution theory, that theory that suggests that creatures actually were mainly very primitve lives, which by time - I mean here millions of millions of years - evolved into creatures that you say all around.

This theory includes human beings !!. I believe it is silly because human has been created by Allah as human. He may have been bigger and different from now but surely he was a human.

Anyway, scientists have found a 47 million years old fossil that they claim as one of the early human ancestors - A phase on the evolution journey -
As I said earlier, I wouldn't take it that this fossil is one of my great great grand mothers as they say in the report. but surely, it is someone's else grand mother !!

The great thing about this fossil that it is perfectly preserved, you can see all the details of the body even some fur can be located !!
The great condition of the fossil - 95% compelete - can be justified by the fact that it was found in a place which is believed to have been a lake where gazes and liquids existed which helped preserving this fossil along with other thousand fossils of animals and fishes.


It is very interesting see a look at the BBC for more details .
