Getting SSH Key for Gitlab & Source Tree

Step 1 : Generate id_rsa public key by typing  : ssh-keygen -t rsa -b 4096 -C "youremail@com" on your command prompt.

Step 2 : Now open public key file and copy paste to gitlab at the ssh key section.

Step 3 : After that go to source tree and navigate to Tools > Add SSH key

Step 4 : Then check the connections  via "ssh -v git@gitlab.com"

Step 5 : If success,  you can now clone , pull, push or check out within your branches.

Step 6 : Otherwise, try git CLI to get it done manually if (Source Tree) problem occurs.

Working with Private Repo (GitLab)

To clone :

git clone https://YOUR_USER_NAME:PASSWORD@gitlab.com/root/filename.git

Redirect if not authenthicated laravel 5.4

the path is defined in app/Exceptions/Handler.php

/**

    {
        if ($request->expectsJson()) {
            return response()->json(['error' => 'Unauthenticated.'], 401);

        return redirect()->guest('elsewhere');

Laravel 5.4 and higher version ( Specified key was too long when doing migration)

Specify a smaller length for your e-mail:

$table->string('email', 250);

Which is the default, actually:

$table->string('email');

And you should be good.

For Laravel 5.4 you can find a solution in this Laravel 5.4: Specified key was too long error, Laravel News post:

As outlined in the Migrations guide to fix this all you have to do is edit your AppServiceProvider.php file and inside the boot method set a default string length:

namespace App\Providers;

use Illuminate\Support\Facades\Schema;
use Illuminate\Support\ServiceProvider;
public function boot()
{
    Schema::defaultStringLength(191);
}

Upgrading to Laravel 5.5 with current project

Step 1 : Change php version that currently your localhost server using (Wamp = php 7.0)



Step 2 : Uninstall and install composer again and select the correct php version (7.0) while setup



Step 3 : If error still occur. Try using 'composer install --ignore-platform-reqs' to setup your project folder

npm run dev

Problem : laravel-5-4-cross-env-is-not-recognized-as-an-internal-or-external-command

You need to make cross-env working global instead of having in in the project.

1) remove node_modules folder

2) run

npm install --global cross-env

3) remove "cross-env": "^5.0.1", from package.json file devDependencies section. Actually, you can skip this step and keep package.json intact. If you prefer.

4) run

npm install --no-bin-links

5) run

npm run dev

and see it working

npm run gulp on root project

Some problems need to settle :

1. error cannot found module "browser-sync

Answer :

Tried these steps. Its work for me.

Globally install gulp.

Next need to install the project’s local dependencies (that’s where it’s looking for browser-sync). To do that,

cd into the project directory and run npm install.

Then try gulp serve.

You can also try following lines

npm i browser-sync --save then

npm start

2. error cannot found module "gulp-sass"

Just do npm update and then npm install gulp-sass --save-dev in your root folder, and then when you run you shouldn't have any issues.

Android ViewPager (Working with Basic Tabs)

Step 1

Instantiate view pager id

viewPager = (ViewPager) findViewById(R.id.viewpager);
setupViewPager(viewPager);

Step 2

Setup View Pager adapter

 private void setupViewPager(ViewPager viewPager) {
        ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
        /* Passing title to adapter */
        adapter.addFragment(new OneFragment(), "Featured");
        adapter.addFragment(new TwoFragment(), "Rentals");
        viewPager.setAdapter(adapter);
    }

    /* Fragment Adapter */
    class ViewPagerAdapter extends FragmentPagerAdapter {
        private final List mFragmentList = new ArrayList<>();
        private final List mFragmentTitleList = new ArrayList<>();

        public ViewPagerAdapter(FragmentManager manager) {
            super(manager);
        }

        @Override
        public Fragment getItem(int position) {
            return mFragmentList.get(position);
        }

        @Override
        public int getCount() {
            return mFragmentList.size();
        }

        public void addFragment(Fragment fragment, String title) {
            mFragmentList.add(fragment);
            mFragmentTitleList.add(title);
        }

        @Override
        public CharSequence getPageTitle(int position) {
            return mFragmentTitleList.get(position);
        }
    }

Step 3 Adding cool transition

  viewPager.setPageTransformer(true, new DepthPageTransformer());

Step 4 Transition Class

public class DepthPageTransformer implements ViewPager.PageTransformer {
    private static final float MIN_SCALE = 0.75f;

    public void transformPage(View view, float position) {
        int pageWidth = view.getWidth();

        if (position < -1) { // [-Infinity,-1)
            // This page is way off-screen to the left.
            view.setAlpha(0);

        } else if (position <= 0) { // [-1,0]
            // Use the default slide transition when moving to the left page
            view.setAlpha(1);
            view.setTranslationX(0);
            view.setScaleX(1);
            view.setScaleY(1);

        } else if (position <= 1) { // (0,1]
            // Fade the page out.
            view.setAlpha(1 - position);

            // Counteract the default slide transition
            view.setTranslationX(pageWidth * -position);

            // Scale the page down (between MIN_SCALE and 1)
            float scaleFactor = MIN_SCALE
                    + (1 - MIN_SCALE) * (1 - Math.abs(position));
            view.setScaleX(scaleFactor);
            view.setScaleY(scaleFactor);

        } else { // (1,+Infinity]
            // This page is way off-screen to the right.
            view.setAlpha(0);
        }
    }
}
