Turn on the Pi

Once on the Desktop, click on the Terminal icon

Type:

REMOTE SUPPORT THROUGH CHROME REMOTE DESKTOP

Teamviewer has been a constant headache in 2020. So I have had to find a teamviewer replacement…and have found Chrome Remote Desktop. So far my experience has been good. Quick, easy install. I can still remotely manage my mining rigs. This guide shows how I connect to a system that runs during the day for a dedicated user (who owns it), and mines at night. When he has an issue, he contacts me and we setup a Chrome Remote Desktop support session using the following excerpt from this link https://support.google.com/chrome/answer/1649523?co=GENIE.Platform%3DDesktop&hl=en

Share your computer with someone else

You can give others remote access to your computer. They’ll have full access to your apps, files, emails, documents and history.

  1. On your computer, open Chrome.
  2. In the address bar at the top, type remotedesktop.google.com/support, and press Enter.
  3. Under “Get Support, “ click Download Download page.
  4. Follow the onscreen directions to download and install Chrome Remote Desktop.
  5. Under “Get Support,” select Generate Code.  
  6. Copy the code and send to the person you want to have access to your computer.
  7. When that person enters your access code on the site, you will see a dialog with their e-mail address. Select Share to allow them full access to your computer.
  8. To end a sharing session, click Stop Sharing.

The access code will only work one time. If you are sharing your computer, you will be asked to confirm that you want to continue to share your computer every 30 minutes.

IPAD PHOTO UPLOAD TO ONEDRIVE FAILS

  • iPad, MAC

My ipad has been setup with OneDrive, and I had initially configured the photos to automatically upload, so I have a backup of them, off my device. The upload worked great for the first upload, but the ongoing iPad photo upload to onedrive fails with no errors showing.

I finally found the fix

On the iPad
Go to Settings
Scroll down to OneDrive
Enable Background App Refresh
Mine was disabled

Over the next day or so, your iPad should begin uploading all of your photos again to OneDrive!

Success!!!

USING ‘SCREEN’ ON A HEADLESS MINER

To set the stage, my mining rigs are setup on Ubuntu 20.04, with NVidia 1080Ti Cards, and they are headless systems. On these systems, I use Putty to connect to them, and run them. You will notice that when you close putty, your miner will stop mining. Which can be a pain, because who wants to always have a Putty connection to their miner, especially when it is a headless system.

A fun little program that I have used for years and never thought of mentioning, is called Screen. Screen allows you to run your headless mining system, without putty being constantly attached, or having a keyboard / mouse / monitor attached.

To enable screen, you can do the following once you are logged in through putty
sudo bash
apt-get update
apt-get install screen
If you are running Ubuntu 20.04 you may find that it is already installed. If it is installed, to run it, simply do the following
screen ./program-name
and the program will run

For me I use it to run my custom mining scripts, so I will cd to the directory, and run
screen ./etc.sh
The mining software will start up, and I can then close Putty, and the rig will continue to mine…..

If at any time you want to reconnect to your miner to see the progress:
Open Putty
Login
Type screen -r
Press Enter
Your screen will reconnect

MINING ETC ON UBUNTU WITH NVIDIA 1080TI

Recently I had to change the software on my rig. My rig is mining ETC on Ubuntu with NVidia 1080TI cards. I had to change it because claymore was not working the way it should with the site ethermine, hence the need to change mining software from claymore to ethminer. The following guide is how i did it.

Login to the headless rig
sudo bash
cd /
mkdir /miner
cd /miner
wget https://github.com/ethereum-mining/ethminer/releases/tag/v0.18.0

Once it downloads you then run
tar -zxvf *.gz
The software will unpack

cd bin
wget https://tacticalware.com/downloads/etc-ethminer.txt
mv etc.txt etc.sh
chmod +x etc.sh
nano etc.sh
Change the wallet address to your wallet
Save the file and Exit
./etc.sh

You should now be mining. Be sure to look at https://etc.ethermine.org/ and monitor your wallet to verify that it is sending data back and forth to the site. It should take about 15 minutes to show up initially, so be patient.

ADDING A DIGIT TO A COLUMN IN POWER BI

  • Power BI

I have an excel file with all of my original data, that i need to modify, once it is in Power BI. To do so, I have worked with a friend to create a simple, but effective code to to this automatically. The zip code is automatically formatted in excel, and changed from 02860 over to 2860. I did not notice it until well after it was within Power BI. So this guide is what I ran through in adding a to a column in Power BI.

Open Power BI
Open the pbix file
Click Home
Select Transform Data
Find the Zip column and highlight it. In My case the column has 2860
Click Add Column
Select Custom Column
Type in the following in the Custom Column Formula dialog box
= Text.PadStart([Zip],5,”0″)
Click Ok

That’s it! I now have a zip code column with the proper formatting of 02860 instead of 2860
