ChatGPT at it’s finest: writing short helpful code without having to do fancy work.

The following is a dialog with ChatGPT. I had this script that I would normally have to hand edit all of the ticker  symbols by adding them to the end of the lines of code. I am sure there is some clever way using sed or awk but, I figured why not get ChatGPT to help.

ChatGPT then was also able to generate the Tags for this post,by feeding the post into a prompt and I used Stable Diffusion to generate the featured image using the blog title as the prompt. Sometimes it is good to use ChatGPT to proofread as well but, this post was short and simple enough not to do that.

I want to show you an output, in the left column are the ticker symbols for a number of cryptocurrencies, I want you to remember all of them as they will be used in the next question that I will pose…..

I don’t have the ability to remember information from one interaction to the next, but I can certainly help you analyze or work with the data you’ve provided in this session. If you have a specific question or task related to this cryptocurrency data, feel free to let me know, and I’ll do my best to assist you!

User

Can you print out all of the symbols in the left column?

Certainly! Here are all the ticker symbols from the left column:

objectivec
AAVE, ACH, ADA, ALGO, AMP, ANKR, ATOM, AVAX, AXS, BAL, BAND, BAT, BCH, BNT, BOND, BTC, CGLD, COMP, CRV, CVC, DAI, DOGE, DOT, ETC, ETH, FARM, FET, FIL, GLM, GRT, ICP, KNC, LINK, LOOM, LPT, LRC, LTC, MANA, MATIC, MIR, MKR, MLN, NKN, NMR, OGN, OMG, OXT, PLA, POLY, QNT, REN, REQ, RLC, RLY, SKL, SNX, SOL, STORJ, UMA, UNI, USD, USDC, XLM, XTZ, YFI, ZEC, ZRX

If you have any specific tasks or questions related to these symbols, feel free to let me know!

User

OK, good, you remembered them. Now for the next step. I am going to show an example using btc and I would like you to create a listing with all of the ticker symbols from the left column. Example: $DIR/rsi-fractals-avgs-bbands-txt-summary.py btc

Sure, I understand. If you could provide an example of the desired output or clarify the specific format or information you’re looking for related to each ticker symbol (similar to the example you provided with btc), I’d be happy to assist you further.

User

I am looking for you to create code that has $DIR/rsi-fractals-avgs-bbands-txt-summary.py on every line but with the ticker symbols from the left column appear on that line right after it.

Certainly! It sounds like you want a list of commands where $DIR/rsi-fractals-avgs-bbands-txt-summary.py is followed by each ticker symbol. Here’s an example Python script that generates those commands:

python
# List of ticker symbols ticker_symbols = [     "AAVE", "ACH", "ADA", "ALGO", "AMP", "ANKR", "ATOM", "AVAX", "AXS", "BAL",     "BAND", "BAT", "BCH", "BNT", "BOND", "BTC", "CGLD", "COMP", "CRV", "CVC",     "DAI", "DOGE", "DOT", "ETC", "ETH", "FARM", "FET", "FIL", "GLM", "GRT", "ICP",     "KNC", "LINK", "LOOM", "LPT", "LRC", "LTC", "MANA", "MATIC", "MIR", "MKR",     "MLN", "NKN", "NMR", "OGN", "OMG", "OXT", "PLA", "POLY", "QNT", "REN", "REQ",     "RLC", "RLY", "SKL", "SNX", "SOL", "STORJ", "UMA", "UNI", "USD", "USDC", "XLM",     "XTZ", "YFI", "ZEC", "ZRX" ] # Directory variable DIR = "$DIR" # Generate commands commands = [f"{DIR}/rsi-fractals-avgs-bbands-txt-summary.py {symbol}" for symbol in ticker_symbols] # Print commands for command in commands:     
       print(command)

Replace $DIR with the actual directory you want to use. This script will generate commands for each ticker symbol, following the format you provided. If you have any specific adjustments or requirements, feel free to let me know!

OK how did it turn out?

This is the output, just as I expected and was looking for. Saved me probably about 15 minutes of tedious hand editing…

What’s it for?

It is screener code that will go into a script that prints out all the cryptos in the list sorted by their position relative to their 20 day moving average. It uses the same logic as used for the Mayer Multiple, except it is on a 20 day MA basis.

X = Current Price / 20DMA

# Sort by desending price/sma20 multiples

the script runs the rsi-fractals-avg-bbands-txt-summary code on all the tickers listed and saves output to…

output-rsi-er-price-sma20-multiple.csv

then sorts the output by the 20sma multiple column

Best relative performers on top, worst on bottom. This idea comes from the book Fortune’s Formula and appears as a technique used by Princeton-Newport. Basically sell the top and buy the bottom ( deep value…maybe), or alternativly short the top and long the bottom. Or in the case of crypto the bottom ones might be just be duds that are always behind the pack, maybe don’t even bother with them.

ChatGPT will create Tags

Finally by posting this post into a prompt you can ask ChatGPT to generate Tags for the post. I used most of them but trimmed a few that were redundant.

Create a hidden WordPress page using bash on the command line

Linux, Server, WordPress, , , , , ,

Recently I was searching around looking for a way to create a hidden page on a WordPress site. It is a hosted site, not on wordpress.com. It is on a Linux server to which I have shell access.

Initially I tried using a plugin that I found that hides pages and posts. Plugins, you got to love or hate them. Love then when they work great right out of the box, hate them when they take a long time to troubleshoot.

Rather than waste too much time with the plugin, I went straight to the command line.

It turns out that if you publish a page and then log into the hosting server, make a directory somewhere under your public_html, change directory into it and execute…

 wget -x -nH your-page-url-to-hide-here

Set to Draft or Private

…then go back it and make the page a draft or under review, so it “disappears” from the menu structure. It will still work as a “cached” HTML page that has been downloaded to the folder that you have created. It will work, pictures and what not that you have loaded in it will be fully functional.

Example of a hidden page

Once the original page is put into draft/under review or private mode, it is gone…

Caveat

I have noticed that caching can get in the way. If your server caches pages, wget may not see the page updated when you make changes. A quick remedy is to set the page to draft/pending review or private, delete the hidden page. I usually use rm -rf from the directory above it and then force it to download the “404” page. Then  you can publish the page re-run wget and it will force it to get the fresh version. Keep note of the size of the file as a hint that it is getting the right one.

Upcoming: Do this with a CGI Script

In an upcoming post, I will cover how to make a CGI script that will allow you to create a hidden page easily without having to use SSH to login to the server.

 

wget options used in this example, from the man page

-x
–force-directories
The opposite of -nd—create a hierarchy of directories, even if
one would not have been created otherwise.  E.g. wget -x
http://fly.srk.fer.hr/robots.txt will save the downloaded file to
fly.srk.fer.hr/robots.txt.

-nH
–no-host-directories
Disable generation of host-prefixed directories.  By default,
invoking Wget with -r http://fly.srk.fer.hr/ will create a
structure of directories beginning with fly.srk.fer.hr/.  This
option disables such behavior.

Configuring Posting via email for WordPress

My Thoughts, WordPress, , , ,

I am testing out the ability to post via a secret email, this is how I created this post, then edited some more in WP.

I fussed with it for a bit, sending emails and expecting results. I didn’t realize that the email reading for WP has to be stroked. So I put together a cron job to stroke the reading of email periodically (daily for the moment, which seems reasonable) via php
using…

php -q /home/yourcpanelusername/path-to-folder/wp-mail.php

Which didn’t work, initially. I kept getting email via cron which has XML in the body, it is an error with a line at the bottom…

<p>Slow down cowboy, no need to check for new mails so often!</p>

Then I tried this

But manually stroking the email by going to the URL where wp-mail.php lives does kick the email to a post as lists it as pending. This in my mind is not terribly useful. I would prefer to send an email and have not be a pending post as I would like to post from email without needing to login to WP, in other words just post it already.

Mysteriously after experimenting with sending a few posts by email, it started to work. I sm not sure why, but checking the mail daily at 1AM, it either gets the messages, creates a pending post and deletes the copies on the mail server as it should and reports this in a CRON email. Or there are no emails for it and it reports that correctly. After an initial weirdness it has been working fine and as expected for several weeks.

Test WordPress Install

My Thoughts, WordPress

This Blog is currently a test install for me to experiment with. I do a lot with WordPress and I wanted to try out a few things, without disturbing any live sites. I do have a server at home that I am in the process of building. My old server died a few months ago and I’ve got some big plans for the new one, such as running OwnCloud, more details to follow on this!. Eventually that server will be my “sandbox” instead of this Blog page for WP experiments after installing LAMP.

 

I do plan on putting some interesting content on this site as time goes on.
