FIND WHERE A BITLY ADDRESS GOES

  • General

From time to time I still run into URL shorteners. I always wonder where it is going to send me, and if I can actually trust the link. This is especially worrisome when you run into URL shorteners on new sites. Well I found a way to note the actuall address of the site that it is trying to send you to.

All you have to do is copy the URL and put a plus at the end of it

Example:


Add the plus at the end of the URL
http://bit.ly/2HK6nTW+

Place it in your address bar, and it will bring you to the page, showing the full URL

Now you can see that
http://bit.ly/2HK6nTW+

SET A STATIC IP ON YOUR RASPBERRY PI 4

This guide assumes that you are running the latest version of Raspbian on your Pi. If you are not, you can follow this guide to get it setup.

How to install Raspbian on your Raspberry Pi 4
https://tacticalware.com/wp-admin/post.php?post=1240&action=edit

My build also uses a FAST M.2 drive instead of the slow Micro SD card:
https://tacticalware.com/boot-raspberry-pi-4-from-m-2-usb-drive/

Now that we have both those straightened out, to set a static IP is simple. Just perform the following:

Open a Terminal
Type:
sudo bash
nano /etc/dhcpcd.conf
Replace hostname with the name of the Pi, I set mine to tacticalware1
Then you will want to
uncomment the following lines and set your address(to uncomment, remove the # from the beginning of them)
#interface eth0
#static ip_address line and set the ip
#static routers line and set it
#static domain_name_servers line and set it
Note that if your local network is 192.168.1.xxx or 192.168.0.xxx use an ip scheme that matches your setup
Ctrl x to save
y
Press Enter
nano /etc/hostname
Make sure you set it to tacticalware1 or whatever your pi’s name is
ctrl x
y
nano /etc/hosts
make sure tacticalware1 is listed in there as well at the bottom of the file, next to 127.0.0.1
ctrl x to save
reboot

Your system will now reboot and your static ip address will now be in effect.

WORDPRESS DOUBLE DASH ISSUE 2021 [SOLVED]

  • General

The dreaded double dash issue is back in wordpress. This issue is where wordpress automatically reformats two dashes, into a single long dash. It needs to be removed in blogs like this ome, where many of the commands you see are infact double dashes. This is the quick fix for it.

Login into your site

Go to: Dashboard

Click Appearance

Select Theme Editor

Choose functions.php

Scroll to the bottom of the page and paste

add_filter( ‘run_wptexturize’, ‘__return_false’ );

Click Update

The issue is fixed

Make sure the ‘ symbol above is correct, if it is the apostrophe that slants forward it will not work. it has to the be the apostrophe character that is straight up/down

You will probably need to do this everytime you update your wordpress theme. So bookmark this page and come back when you need to fix it next time.

BESTBUY BOT RUNNING ON RASPBERRY PI

I have been trying for weeks, if not months, to get my hands on the new AMD and NVidia video cards, and just cannot. They are always sold out on bestbuy.com, amazon and many other sites. So I had taken a deeper dive into why this is happening….and it is one simple word…bots.

Thankfully one user on github was sick of it too, so they wrote an open source bot, and released it to everyone, to help level the playing field. Below you will find the info on how to setup this bot to help you, do your normal holiday shopping, against these bots.

First you will need to follow this guide:
https://tacticalware.com/install-ubuntu-desktop-20-10-64-bit-os-on-raspberry-pi-4/

Once you set your Raspberry Pi up, you can pick up the rest here:

From the Desktop of your Raspberry Pi
Open a terminal and type the following:
sudo bash
Enter your password
apt- get update
apt-get upgrade
y
Your Pi will update

Once it is updated, run the following
apt-get dist-upgrade
y
The distribution will upgrade now

After it finishes updating, type the following
mkdir /installs
chmod 777 /installs
cd /installs
apt install git
git https://github.com/Hari-Nagarajan/fairgame.git
reboot

After your system reboots, from the desktop
Open a terminal
sudo bash
Enter your password
cd /installs/fairgame
apt install python3-pip
pip install pipenv
pipenv shell
pipenv install
This will probably fail with an error, however the major dependencies have been satisfied, so your bot will work.

Now time to test the bot
python3 app.py bestbuy –sku [6440913]

Success!

From here you will want to refer to the Readme in your /installs/fairgame directory to see exactly how you will want to run the bot now that it works.

RASPBERRY PI GREEN SCREEN

An issue that you will find with the Raspberry Pi’s are the Green Screens, as show in the picture. Green Screens are the result of a corrupted Operating System. The simple fix for this, is to reinstall the OS onto the Micro SD card, or onto the M.2 ssd if you run your Pi devices the way I do.

BOOT RASPBERRY PI 4 FROM M.2 USB DRIVE

If you want huge performance increases, consider getting rid of the Micro SD card, and moving your data and OS over to an M.2 Drive on the Raspberry Pi. How do you do this, you ask. First, make sure you have the same hardware as me, in order to follow along. Second, run through the following guide.

If you need to do this from scratch, follow this guide to setup your Raspberry Pi: https://tacticalware.com/install-raspbian-os-on-raspberry-pi-4/

Then, make sure your firmware / eeprom is up to date. If you need assistance with it, follow this guide:
https://tacticalware.com/update-new-raspberry-pi-4-firmware-eeprom/

Once you have both steps above completed, you can move onto setting up the M.2 drive

For this, I have inserted a WD 500GB M.2 Drive into a USB 3.0 dongle, and have it connected to my Pi. If you want to get the same parts as I have, skip to the bottom of this page.

Now, you will want to connect your M.2 dongle to your Raspberry Pi 4, and boot it up.

Once you are at the Desktop:
Open a Terminal
sudo bash
raspi-config
Select option 6 – Advanced Options
Choose option A6 – Boot Order
Select option B1 – USB Boot
Press Enter
You should now be on the “Usb device is the default boot device” screen
Select OK
Scroll to Finish and select it
You will see the message:
Would you like to reboot now?
Choose NO

Back on your Raspberry Pi 4 Desktop
In the top left corner, click on the Raspberry to access the drop down menu
Select Accessories
Scroll over to and choose SD Card Copier

A dialog box will open
If you have the same setup as me, using the same hardware below, you will want to select the same options, otherwise you will have to choose the relevant settings for you
Copy from Device – Select the option for the SC32G
Copy to Device – Select the option for the WDS500G3
Select Start
Choose YES – to erase all contents
Click OK once the contents are copies over successfully
Select Close
Shutdown your Raspberry Pi 4
Remove your Micro SSD
Power the Pi back on, it should now boot from the USB M.2 Drive
Open a terminal
Type
sudo bash
raspi-config
Select option 6 – Advanced Options
Choose option A1 – Expand filesystem
Press Enter
Root File system will be resized
Click Ok
Reboot

You are done!
