how to boot ubunutu / linux from grub command line [solved]

I'm st grub command line...

grub> _

type the following:

ls

your will get a list of drives / partitions

(hd0) (hd0,gpt8) (hd0,gpt7) (hd0,gpt6) (hd0,gpt5) (hd0,gpt4) (hd0,gpt3) (hd0,gpt2) (hd0,gpt1)

you need to probe each one to find which os is on each

e.g.

grub> ls (hd0,7)
(hd0,7):Filesystem is ext2.
grub> _

and you can also check that vmlinuz is present by typing
ls (hd0,7)/

this will give you list of files

now we set the root for boot

set root=(hd0,7)
linux /vmlinuz root=/dev/sda7
initrd /initrd.img
boot

then when ubuntu starts run the boot repair program

laravel - introducing a favicon (favicon.ico) to the app website [answered]

Here's a quick and easy on how to add favicon.ico to a page using laravel.

1. Put your favicon.ico somewhere tidy
e.g. public/assets/img/

if your laravel app site is
/var/www/mywebsite/

put the favicon favincon.ico in the

/var/www/mywebsite/public/assets/img/

2. add the link code to your web page
Assuming you want the icon on every page

Link Code:
<link rel="shortcut icon" href="{{ asset('assets/img/favicon.ico') }}">

link code goes in the head section

edit resources/views/layout.blade.php
to access the head section

here's an example

<!doctype html>
<html lang="en">
@section('html-head')
<head>
        <meta charset="UTF-8">
        <title>{{ $pageName or 'MyWebsite' }}</title>
        <link rel="shortcut icon" href="{{ asset('assets/img/favicon.ico') }}">
        <meta name="viewport" content="width=device-width, initial-scale=1">

        @section('html-head-includes')

                @if (App::environment() == 'local')
                        {!! HTML::style('/assets/lib/bootstrap/dist/css/bootstrap.css') !!}
                        {!! HTML::style('/assets/css/bootstrap-theme.css') !!}
                @else
                        {!! HTML::style('/assets/lib/bootstrap/dist/css/bootstrap.min.css') !!}
                        {!! HTML::style('/assets/css/bootstrap-theme.css') !!}
                @endif

                {!! HTML::style('/assets/lib/font-awesome/css/font-awesome.min.css') !!}
                {!! HTML::style('/assets/css/cityadmin.css') !!}

        @show

</head>
@show

@section('html-body')
<body>

        @yield("content")

</body>
@show
</html>

3. Test your websiteI find a new incognito window useful for testing new icon changes as nothing is previously cached.

Windows Vista - how to reduce size of Datastore.edb

ANSWER: defrag the database using esentutl.exe

Here's what I did

C:\Windows\system32>esentutl /d C:\Windows\SoftwareDistribution\DataStore\DataStore.edb

Extensible Storage Engine Utilities for Microsoft(R) Windows(R)
Version 6.0
Copyright (C) Microsoft Corporation. All Rights Reserved.

Initiating DEFRAGMENTATION mode...
Database: C:\Windows\SoftwareDistribution\DataStore\DataStore.edb
Temp. Database: TEMPDFRG4872.EDB

Defragmentation Status (% complete)

0 10 20 30 40 50 60 70 80 90 100
|----|----|----|----|----|----|----|----|----|----|
...................................................

Moving 'TEMPDFRG4872.EDB' to 'C:\Windows\SoftwareDistribution\DataStore\DataStore.edb'..

Note:
It is recommended that you immediately perform a full backup
of this database. If you restore a backup made before the
defragmentation, the database will be rolled back to the state
it was in at the time of that backup.

Operation completed successfully in 27.875 seconds.

Now i have an extra 400MB free - makes the difference on vista!

sugar crm rest api example

REST api Example

source: http://urdhva-tech.blogspot.co.uk/2013/02/rest-api-example.html

At times developers find it so difficult to find simple and running example of REST API to perform CRUD operations on SugarCRM.. There are plenty of tutorials, blogs, developer guides explaining same thing. Still for an ease for ourselves and to the hunters of same, writing the same thing all over again. 

REST Example

This blog post explains how to login to SugarCRM instance with admin user.

<?php

// specify the REST web service to interact with

$url = '<SITE_URL_OF_SUGAR>/service/v2/rest.php';

// Open a curl session for making the call

$curl = curl_init($url);

// Tell curl to use HTTP POST

curl_setopt($curl, CURLOPT_POST, true);

// Tell curl not to return headers, but do return the response

curl_setopt($curl, CURLOPT_HEADER, false);

curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);

// Set the POST arguments to pass to the Sugar server

$parameters = array(

    'user_auth' => array(

        'user_name' => 'admin',

        'password' => md5('<ADMIN_PASSWORD>'),

        ),

    );

$json = json_encode($parameters);

$postArgs = array(

    'method' => 'login',

    'input_type' => 'JSON',

    'response_type' => 'JSON',

    'rest_data' => $json,

    );

curl_setopt($curl, CURLOPT_POSTFIELDS, $postArgs);

// Make the REST call, returning the result

$response = curl_exec($curl);

// Convert the result from JSON format to a PHP array

$result = json_decode($response);

if ( !is_object($result) ) {

    die("Error handling result.\n");

}

if ( !isset($result->id) ) {

    die("Error: {$result->name} - {$result->description}\n.");

}

// Echo out the session id

echo $result->id."<br />";

$session = $result->id;

Create a new record in Lead module
 As we have session id, we are logged-in!, we will use that session id to create a new record.
Here we used set_entry method for that we need three parameters

1) session : pass current session id
2) module : module name to create a record
3) name_value_list : name value list combination

Let's see that in below code snippets

$parameters = array(
    'session' => $session, //Session ID
    'module' => 'Leads',  //Module name
    'name_value_list' => array (
            array('name' => 'first_name', 'value' => 'David'),
            array('name' => 'last_name', 'value' => 'Boris'),
            array('name' => 'status', 'value' => 'New'),
            array('name' => 'lead_source', 'value' => 'Web Site')
        ),
    );
$json = json_encode($parameters);
$postArgs = 'method=set_entry&input_type=JSON&response_type=JSON&rest_data=' . $json;

curl_setopt($curl, CURLOPT_POSTFIELDS, $postArgs);

// Make the REST call, returning the result
$response = curl_exec($curl);

// Convert the result from JSON format to a PHP array
$result = json_decode($response,true);

// Get the newly created record id
$recordId = $result['id'];

print "New Record Created with ID ".$recordId;

Read detail of top 5 leads having work phone, as an example.

// Let us fetch detail of a Lead

$fields_array = array('first_name','last_name','phone_work');

$parameters = array(

    'session' => $session,                                 //Session ID
    'module_name' => 'Leads',                             //Module name
    'query' => " leads.phone_work IS NOT NULL ",   //Where condition without "where" keyword
    'order_by' => " leads.last_name ",                 //$order_by
    'offset'  => 0,                                               //offset
    'select_fields' => $fields_array,                      //select_fields
    'link_name_to_fields_array' => array(array()),//optional
    'max_results' => 5,                                        //max results                 
    'deleted' => 'false',                                        //deleted
);

$json = json_encode($parameters);

$postArgs = array(
    'method' => 'get_entry_list',
    'input_type' => 'JSON',
    'response_type' => 'JSON',
    'rest_data' => $json,
    );

curl_setopt($curl, CURLOPT_POSTFIELDS, $postArgs);

$response = curl_exec($curl);

// Convert the result from JSON format to a PHP array

$result = json_decode($response);

print "<pre>";
print_r($result);
die;

Update a lead status "New" to "Assigned" for lead which we have just created. We can use set_entry method with specified record id to update a value.

$recordId = "<Your 36 character record id>"; 

$parameters = array(
    'session' => $session,
    'module' => 'Leads',
    'name_value_list' => array(
            array('name' => 'id', 'value' => $recordId),  //Record id to update
            array('name' => 'status', 'value' => 'Assigned'),
        ),
    );
$json = json_encode($parameters);
$postArgs = 'method=set_entry&input_type=JSON&response_type=JSON&rest_data=' . $json;

curl_setopt($curl, CURLOPT_POSTFIELDS, $postArgs);

// Make the REST call, returning the result
$response = curl_exec($curl);
// Convert the result from JSON format to a PHP array
$result = json_decode($response,true);

// Get the newly created record id
$recordId = $result['id'];
print "Record Updated, Updated id ".$recordId;

Delete a record via web-service.  It is as simple as we update record with id. Here we need to provide id and deleted equal 1.

$recordId = "<Your 36 character record id>"; 

$parameters = array(
    'session' => $session,
    'module' => 'Leads',
    'name_value_list' => array(
            array('name' => 'id', 'value' => $recordId),
            array('name' => 'deleted', 'value' => '1')        //Deleted flag
        ),
    );
$json = json_encode($parameters);
$postArgs = 'method=set_entry&input_type=JSON&response_type=JSON&rest_data=' . $json;

curl_setopt($curl, CURLOPT_POSTFIELDS, $postArgs);

// Make the REST call, returning the result
$response = curl_exec($curl);
// Convert the result from JSON format to a PHP array
$result = json_decode($response,true);

// Get the newly created record id
$recordId = $result['id'];

print "Record Deleted!, Deleted record id is ".$recordId;
