FreshRSS and RSS Feed Posts

Ramen Junkie 0Comment

Keen observers (ha ha ha no one reads this), might have noticed that a few posts of links showed up in the feed.  These are basically, stories I read in my RSS reader that I found interesting, and wanted to share, or at least, keep track of.  The posts as of now are a little ugly, and I’ll probably clean up the formatting over time, but I wanted to go ahead and write a bit about the process.  I’ll have the Code on Github at some point.

As for the factors, firstly, this is something I’ve wanted to have on my blog for a while.  Like a long while.  I might even try to see if there are ways to better slit up the links by topic later.  A fair number of blogs I subscribe to have these sort of link digest posts, and I’ve always just liked the idea.  It’s also good for personal reference to when I may have read something.  It is limited as it only comes from y RSS Reader.

Speaking of my RSS Reader.  I’ve moved on from TinyTinyRSS, for a few reasons.  One, the interface is a little meh, honestly.  Maybe the newer version is better but it’s only available in Docker, and Docker is such a PItA to use.  Also, while looking for alternatives, it sounds like the folks who make TTRSS are kind of a bunch of gatekeeping jerk types, and I’d rather not support that.  I also find the need to keep the update daemon running with Screen to be a pain.  So I’ve moved over to FreshRSS, which I just run locally on a Raspberry Pi.  I may move it to a publicly accessibly machine at some point, but I am not entirely convinced that TT-RSS wasn’t the entry point for my previous server malware woes.

So, like TT-RSS, Fresh RSS has a way to get an RSS feed out of your Favorited posts.  In the past I’ve used tools like IFTTT to automate posting these links around, but I don’t use IFTTT anymore for reasons I’m not going into.  Fortunately, I’ve been working to become a pretty good Python coder for the last month or so.  So instead I wrote a script.  

It’s not even a particularly complicated script.  There are only two things it really needs to do, get new articles, and then post them to WordPress. Since the script runs locally, on the same Raspberry Pi even, it easily can reach and pull the RSS feed.  One nice thing I noticed with Fresh RSS, the feed included a time interval, so just getting new posts was super simple, because the interval is just “24” for “24 hours”.  The script eventually will run on a cronjob at the exact same time daily.  Anyway, after pulling the RSS, the entries are already in an easily usable Dictionary.  which gets fed into the construction of the WordPress Post.

def get_feed(feed_url):
    NewsFeed = feedparser.parse(feed_url)
    return NewsFeed

The posting part was pretty easy as well, WordPress has an API, and Python also has a library that can use that API.  It just needs some log in information and a post payload to send.  

def make_post(NewsFeed):
    wp = Client(f'https://{wp_url}/xmlrpc.php', wp_user, wp_pass)
    post = WordPressPost()
    post.title = f"{cur_date} - Link List"
    post.terms_names = {'category': ['Link List'], 'post_tag': ['links', 'FreshRSS']}
    post.content = f"<p>Blogging Intensifies Link List for {cur_date}</p>"
    for each in NewsFeed.entries:
        post.content += f'{each.published[5:-15].replace(" ", "-")} - <a href="{each.links[0].href}">{each.title}</a></p>'

The trickiest part was formatting the date a bit prettier.  I mentioned cleaning up the formatting a bit, I’m thinking maybe a simple invisible table, so the date and the links don’t wrap oddly like they do now.   i also added a check that if there are no new favorited posts, it will skip making a post.  Otherwise I’ll end up with empty posts on days I forget to check my feed reader

While writing the script, at first I was just outputting a text copy of the post to the console until satisfied.  Eventually, I pushed out a real post, then verified that things worked.  The next day, was just a straight test by opening the project, then running it again.  The third day, I copied the files and installed the lobraries needed, then posted from the Pi.  Phase 4 of this will be to set up Cron to run it automatically.  If that works then it will certainly, “just run” for the foreseeable future.

Back to web development again, but with a different twist this time.  Instead of scraping things, we’re learning Flask, to produce little Python based Websites.  In doing these exercises, I find I am kind of wondering why one would use Python over say, Apache, or NGINX or even IIS.  I can sort of see where it’s useful, and maybe later we will get to more of it’s usefulness.  My primary issue is that the HTML code part of it ends up being VERY specifically Flask based.  Like flask looks for images and CSS in specific folders.  Plus if you use any sort of variables, they all get passed to the HTML in a very particular way.

I had considered that it might be useful for sharing some of the code I have written through my web server, but in my research, things like Tkinter and Turtle don’t work at all through Flask.  I was kind of hoping it was smart enough to produce little Browser pop ups or something to render the graphics out.

This section isn’t super complex so far, but it wraps up the Intermediate+ section with a little interlude for Bootstrap in between, so I figure it’s a good little chunk to keep in it’s own write up.

As usual, the code is all on Github.

Day 54 – Intro to Flask

There was literally no project today really.  We created a basic “Hello World” Flask server, then created some Decorator Functions.  It was interesting, but not really that exciting to write up.  I do somewhat question the usefulness of a Decorator a bit, versus just having a function that takes an input and modifies it directly.

## Day 55 – Higher Lower Game Returns

The Day 55 Lessons were a bit better.  We covered Decorators a bit more and how to handle URLs in Flask, which brings me back to the “Is this better” I mentioned in the opening, since once again, the code will get weird to use outside of Flask.

I had a lot of fun with the project though.  It’s a web version of the “Higher-Lower” Game from way back on Day 14.  You Pick a number, it tells you if it’s higher or lower, only with web pages.  It was essentially a way to learn about using Dynamic URLs in Flask, but spiced up for fun.  I added a nav bar to mine so the user didn’t have to type a URL and could just click the next number to guess.  I also used a bunch of silly GIFs from my favorite musicians instead of Cat GIFs on each page.  

It’s kind of useless, but it was fun to build.

Day 56 – Personal Website

This day was mostly about how to quickly import existing code to Flask.  It involved a couple of practice projects and a “real” project.  The first Practice was taking the Lesson 41-44 website and importing it to Flask.

The second practice was to use someone else’s template and import it to Flask, as well as modifying and simplifying that code.

The final project was to build a simple “Name Card” website with some social links.  Essentially, it was a repeat of the second practice, but actually replacing images and information.  I kind of prefer the previously made CV website and it’s easier to hose on the web so I’m going to stick with that for now.

Day 57 – Blog Capstone Project Part 1

This project picks up in Day 59 with the start of the Advanced Section of the course.  The basic idea here was to build a simple blog interface that would read some generic JSON Posts and display them, and then let users click into each blog post to read more.

I’m particularly proud of my result, which only uses one HTML file, that varies if the user clicked on a blog post or not.  I feel like it was a pretty slick solution.  The starter files also included a file to make a “Post class”.  Using this class was not part of the assignment, but I suspect it will come up later, so I went ahead and built it, though I didn’t use it to read the blog posts.

If this comes out alright, I may actually use it somewhere, I’ve been looking for something to put on Joshmiller.net.  Though I also don’t really NEED another Blog outlet.  I barely maintain the one I regularly use now.

Here we are now with a few more automated bot tasks.  It’s been a fun series of lessons, though I enjoyed using Beautiful Soup more then Selenium.  Selenium runs into too many anti-bot measures on the web to be truly effective.  I mean, it’s definitely a useful too, but in my experience, it’s not reliable enough.  BS seems to be much more effective, though it can’t really interact with pages.

In the long run, I think I am more just irritated by “clever bull shit” on web pages that makes both pieces of software a pain to work with. Take Instagram, none of the classes or ids are anything but jumbled characters.  The code feels like it was written by a machine, and it probably was.

Also, this round is a bit shorter than before because the course is veering off into a new direction with Flask Apps, so it seemed appropriate to wrap things up on the Automation Section of the Projects.

Day 51 – Twitter Speed Complainer

This project is great, because this is something I have tried to run from other people’s code but it never seems to actually work.  Now, I just have my own code to run.

EZ Mode.

It will need something with a desktop to run it on, but I have a while Windows PC for running random shit and a mess of Raspberry Pis.  I don’t even care about the complaining part, in fact, I would rather not, I just want to track Internet speed.  I may even change this ti push to a spread sheet or database or something later.

But for now, it Tweets.

So, the Speed test part was easy, though I used SpeedOf.me instead of SpeedTest.net, because SpeedTest.net supposedly will give dodgy numbers by partnering with ISPs and putting servers in ISP data centers.  I just prefer SpeedOf.me mostly, it’s cleaner.

The Twitter part was tricky… ish…  So, a common problem I keep running into with Selenium, is it thinks my Bot Programs, are Bots.  

I’m so offended for my Bots, accusing them of being Bots.   They run into captchas and email verifications and just flat out fail to log in or load half the time. It makes sense, captchas and email verifying exist, 100% to stop people from abusing things like, Selenium. Fortunately, Twitter Bots is one thing I do have a fair amount if experience with. I wrote one ages ago that just tweeted uptime of the server.  I wrote one script that would pull lines from a text file and tweet them out at an interval.  I have another Python based bot that tweets images.  What do these Bots do differently?  They are 100% Bots, running with the proper Twitter Bot Based AI, and labeled as such.  

So, since Selenium was being a pain to deal with using Twitter, I pulled out my Image Posting Bot code and scavenged out the pieces I needed, which was about 4 or 5 lines of code.  It uses a Python Library called Tweepy.  In order to use Tweepy, you have to use the Twitter Developer console to get API Keys, which I already had.

Day 52 – Instagram Follower

Another almost useful project. For this project, you open up Instagram and log in, then it opens an account of your choosing, and follows, anyone following that account.

Now, while I have a love/hate relationship with Instagram, I am not super interested in cluttering up my feed with thousands of accounts.  So, while I did complete the task, I set it up to ONLY follow the first 10 accounts.   I also added a check to make sure I wasn’t already following said account.

I may revisit this again later with other, more useful ways to interact with IG.  Maybe instead of following random people from another account, it auto follows back.  Or maybe it goes through “suggested” and looks for keywords in a person’s profile and follows them.

Day 53 – Zillow Data Aggregator Capstone

The final project for this section combines Selenium and Beautiful Soup to aggregate real estate listings from Zillow into a Google Spreadsheet doc.  I quite liked this one actually, it’s straight forward and relatively harmless.  I did run into an issue where it started thinking I was a Bot, but by that point, I knew I could successfully scrape what I needed from Zillow, so I commented out the Zillow call and replaced it with a file load using an HTML file snapshot of the Zillow page.

This was very easy to slide in as a fix because I was already pulling the source code using Selenium into a variable, then passing that variable to Beautiful Soup.  It was simply a matter of passing the file read instead.

Scraping the data itself was a bit tricky, Zillow seems to do some funny dynamic loading so my number of listings and addresses and prices didn’t always match.  To solve this, I added a line that just uses whichever value is the smallest.  They seem to capture in order, but eventually, some fell off, so if I got 8 prices and 10 addresses, I just took the first 8 of each.

Another issue I came across, the URLs for each listing, don’t always have a full URL.  Sometimes you had to add “https://www.zillow.com” to the front.  It wasn’t a hard fix,

if “zillow” not in link:

link = “https://www.zillow.com”+link

There was also an issue with the links because each link shows up twice using the scrape I was using.  A quick search gave a clever solution to remove duplicates.  It’s essentially:  list = dictionary converted to list(list converted to dictionary).  A Dictionary can’t have duplicate keys, so those get discarded converting the list to a dictionary, and then that result just gets flatted back out into a dictionary.

Lastly was the form entry itself.  The Data Entry uses a method I’ve used before for entering data to Google remotely, with Google Forms.  Essentially, Selenium fills out and submits the form over and over for each result.  I had a bit of issue here because the input boxes uses funny tags and are hard to target directly.  Then my XPATHs were not working properly.  I fixed this by adding two things, one, I had Selenium open the browser maximized, to make sure everything loaded.  Second, I added more sleep() delays here and there, to make sure things loaded all the way.  

One thing I have found working with Selenium, you can never have too many sleep()s.  The web can be a slow place.

Things are continuing to be interesting and useful here with the introduction of Beautiful Soup, a tool used to parse unstructured data into usable structured data.  Well, more or less that’s what it does.  Useful for parsing through Scraped Web Page data that does not have it’s own API available.

As normal, everything is on GitHub.

Day 45 – Must Watch Movies List and Hacker News Headline Scraper

As an introduction to using the tool, Beautiful Soup, we had two simple projects.  The training project actually feels more useful than the official project of the day, though I also remixed the training project a bit.

The “Project of the Day” was to scrape the Empire Magazine top 100 Must watch movies and output them to a text file.  I am pretty sure this list does not change regularly and this it’s sort of a “one and done” run.

The trainer project was more interesting, because it scraped the news headlines from Hacker News, a Reddit-like site centered around coding and technology that is absolutely bare bones in it’s interface.  The course notes were just to get the “top headline of the day”, but I modified mine to give a list of all headlines and links.  I will probably combine this with the previously covered email tools to get a digest of stories each day emailed to myself.

Day 46 – Spotify Musical Time Machine

This one combines the web scraping with the use of APIs which was covered previously.  Specifically the Spotify API.  The object is to get the user to input a date, then scrape the Billboard Top 100 for that date and create a Spotify Playlist based on the return.

This one was actually tricky and, as I often do, I added a bit to keep it robust.  Firstly I created a function to verify if the entered date was, in fact, a valid date.  Knowing my luck, there is a function that does this in Date Time, but writing it up was fun.  It could be better though, it only verifies if the day is between 1 and 31, for example.  Something I may clean up later I think.

The real tricky part was dealing with the scraping.  Billboard’s tables are not very clean and not really scrap-able.  I had come up with a way to get all the Song Titles, but the resulting list was full of garbage data.  I set about collecting the garbage data out by filtering the results list through a second list of keywords, but I noticed someone int he comments had found a simple solution of using Beautiful Soup to search for “li” (list items) with an “h3” (heading 3), which easily returned the proper list.  

So I tried the same for the artists, filter by “li” then by “span” which …. returned 900 items.  So I added another filter on the class used by the “span” containing the artist, which did not help at all.  Fortunetely, I already had solved this problem before while working on the Song List.  I created a list of keywords and phrases to filter, then ran my result across it, eventually I was able to output 100 sets of “Song Title – Artist name”.

The real tricky part was using the Spotify API.   Ohhhh boy what a mess.  There seems to be several ways to authenticate, and they don’t work together, and the API Documentation for Spotify and SpotiPy are neither amazing. It took a lot of digging on searches and testing to get the ball rolling, then some more help with code around the web.  But hey, that’s part of what coding is, “Making it work”.

The first issue was getting logged in, which meant using OATH and getting a special auth token, which Spotipy would use to authenticate with.  

The second issue, once that was working, was to create the playlist, which didn’t end up being too hard, just one line of Spotipy code and output the goof ID key to a variable from the response. Still, I deleted so many “Test List” playlists from my account.

So, the real tricky part, was that Spotify doesn’t work super great if you just search with “artist” and “track”.  Instead you get the ID of the artist, then search within that artist for the track, which works much more smoothly.  Why? To add tracks to a playlist, you add them by Spotify IDs.  Thankfully, I could throw a whole List of them up at once.

The end result works pretty flawlessly though, which is cool.  Though It also shows some of the holes in the Spotify Catalogue as you get into older tracks.  My playlist for my birthday, in 1979, is missing 23 tracks out of 100.

Also, I may look into if there is an API for Amazon Music int he future, since that is what I use instead of Spotify, sometimes.

Day 47 – Amazon Price Tracker

Ok, this one will actually be useful to me in the long run.  Like actually useful.  I already use sites like Camel Camel Camel but running my own tracker would be even better.  Especially because one of my other primary hobbies is collecting Plastic Crack (toys).  Geting deals on things is definitely useful, especially given how expensive things are these days.

Also, I have not found a good way to monitor for sales/price drops on eBooks, which is another advantage to straight scraping web pages.  

So I even added to this one a bit.  Instead of looking for one item, it reads links and desired proces from a text file.  Now, if you look at the code, it probably could be cleaned up with a better import, treating it as a CSV instead of raw text, but I wanted to keep things as simple as possible for anyone who might run this script to monitor proces.  It’s just “LINK,PRICE”.  Easy, simple.

Day 48 – Selenium Chrome Driver

The Day 48 Lesson was an intro to the Selenium Chrome Driver software.  This is a bridge tool, that I imagine can connect to many languages, but in this case we used Python, that can open it’s own dummy web browser window, then read and interact with it.  

So the first bit was just some general example, followed by actually using it to pull the events list from Python.org and dump them into a dictionary.  I could actually see this being useful for various sites because so few sites have easy to find calendar links for events.  I’m sure there is some way to add calendar events to a calendar with Python.  Just one for the “future projects” list.

Afterwards we learned about some interaction with Selenium, filling in forms and clicking links to navigate Wikipedia.  

Finally the day’s project was to automate playing a Cookie Clicker game.  These “Clicker” games are pretty popular with some folks and basically amount to clicking an object as quickly as possible.  The game includes some upgrades and the assignment itself was pretty open on how to handle upgrades.  There was a sort of side challenge to see who would get the highest “Cookies Per Second”.  I set mine up to scan the prices each round and if something could be bought, buy it.  This got me up to about 50 CPS after 5 minutes.  It could be better.  I may go back and adjust it to stop buying lower levels once a higher level can be bought, which I think might be a better method.  Why buy Grandmas when you could buy Factories.

Day 49 – Linked in Job Applier

So, I completely overhauled this one, but kept it in the spirit of things, because the point is more to practice using Selenium in more complex ways.  The original objective, was to make a bot that would open LinkedIn, sign in to your account, go to the Jobs Page, search for “Python Developer”, find jobs with “Easy Apply” and click through the Apply Process.

I am not in the market for a job, so applying for random jobs seems like a dumb idea.  I also use 2-Factor on my LinkedIn account, so logging in automatically would be quite impossible.  It was suggested to make a “Fake Account” to get around this but that seems a bit rude.  It also suggested simply following companies instead of applying, but I’d rather not clutter up my feed with weird false signals.

So instead…

My Bot will open LinkedIn, go to to the Jobs Page for each term in an array of job terms individually, (for the test I used “Python Developer” and “Java Developer”).  Then it takes those results, strips out the Company Name and URL to the Job Opening, and compiles them into an email digest that it sends out.  

One issue I did have is that LinkedIn apparently uses different CSS for Chrome versus Firefox, because I was just NOT getting the results back for the links to each job, and it turns out the link bit has a different Class in Chrome, which Selenium was using, than Firefox, which I was using to inspect code (and use as my browser).

Anyway, it works in the spirit of what was trying to be accomplished, without actually passing any real personal data along.

Day 50 – Tinder Auto Swiper

So, I am really not in the market to use Tinder at all.  I was going to just skip this one.

Then I decided, “You know what, I can make a fake profile with a “https://www.thispersondoesnotexist.com/” profile.

But then it seems dumb to get people to match with a bot.

No wait, I can set up the bot to Reject everyone, swipe, whatever direction “reject” is.  No matches!

Oh, it needs a log in via Google, Facebook, or Phone Number.  Never mind.

No wait, I have some old Facebook Profiles for a couple of my cats, I will just use one of those to log in with!

Oh, it still wants a phone number.

So anyway, I decided even trying to fake it was not worth the trouble.   But hey, Halfway there!

100 Days of Python, Projects 32-40 #100DaysofCode

Things are ramping up a bit again here.  Now we get all sorts of fancy API calls for real time data.  This will definitely be useful for later personal projects, along with the email notifications.  I will probably be running dozens of scripts on a Pi or my web server by this time next year.  This is the sort of stuff I really dig, keeping notice of what’s going on with things.

As usual, my Github Repository for all this code is here.

Day 32 – Sendmail (Birthday and Quote Email-er)

So, I am sure on some level, I was aware that “Python can probably send an email”, but I’ve never really looked into it much.  But actually making it happen is a lot cooler, and it’s simple enough that frankly, I will probably build a class that I can stick in other projects, later.

Also fun, I already have a paid web host that can run cron jobs, or even just a bunch of Raspberry Pis, so anything I made on this next section of projects, I can easily automate to actually use right off.

The bigger thing I actually learned how to work in this chapter, is .gitignore.  Which was not part of the lesson.  I set up a fresh email account for sending mail with these scripts and it’s using easily revoked App Passwords, but since I am posting my work to Github, there is a risk of accidentally posting a file with actual authentication information to the public.  Fortunately, my experience in PHP kicked in immediately with how to handle log in data properly.  For starters, it all goes in it’s own separate file and imported.  This makes it easy to edit later if needed.  It also means, I can tell Git to ignore these files when posting, using the .gitignore file.  

Because I am keeping all of the projects (so far) in one repository, it did become tedious to .gitignore every copy of auth.py, I found that adding “**/auth.py”, which is a bit of bash shell script syntax, is enough to omit all iterations of auth.py, automatically, across all sub-directories.

So my local copy runs fine, but the online copies are all missing the auth.py files.  Easy.  And if I fuck it up for some reason well, you can’t log into the gmail account with the app token, so the account is safe.  It’s used only for this purpose, so nothing of value is on the email of that account, maybe someone could send emails as that account, but chances are I would realize I screwed up and immediately revoke and reset the App Password.

Day 33 – ISS Notifier

It’s too bad the International Space Station (ISS) is getting de-orbited soon, this nice little tool will, unfortunately, be useless soon.  Anyway, this lesson was more work with API calls.  The app pulls the current position of the ISS, in latitude and longitude, then compares it to the lat/lon entered for the app (the user’s position).  It also makes a second API call to check when Sunrise and Sunset are locally, to find out if it’s currently night time out, since you can’t see anything during the day.

If it’s night time, and it’s within 5 degrees Lat/Lon, of the user, it sends an email to notify that the ISS is potentially visible overhead.

I actually took this one and put it on my web server running every ten minutes, so we’ll see if I ever get any emails from it.

We also made a silly little Kanye Quote app, that pulls and populates Kanye West quotes to a quote box with a little cartoon Kanye.

Day 34 – Quiz Game Revisited

I called it, for the most part.  Back on Day 17, we made a simple text Quiz Game.  And the way it was put together, I was pretty sure it would come back to get a GUI in a future lesson, and here it is.  Additionally, it got a nice API call to the OpenTrivia API to get fresh questions every run.  

We also configured the Tkinter interface as a class, instead of as part of the main code, which was different, but not super tricky.  

I want to go back and add a title screen with options for topics, number of questions, and difficulty later.  I did make a few simple modifications.  I didn’t like the Red/Green for Incorrect/Correct, so mine just says “Correct” or “Incorrect”.  I also added a final splash screen of the final score.  Additionally, I use a try/except in the data gathering code, and left the original data in the file.  If the API fails to load, it will load the original tech questions I built for it.

Day 35 Rain Notifier

So, the main purpose for this app was to use apps which require authentication.  Also, to send a text message instead of an email, using Twilio.

Getting the weather wasn’t too tricky, except that the suggested API seemed really invested in getting a credit card from me.  I’m not adverse to this, and it looks like I would get 1000 free calls per month, way more than I would need at about 33 per day, but I opted to just use an alternative API.  The alternative I believe will only work for a bit before the “free trial” runs out, so this won’t be as useful in the long term without revision.  

The point is more the practice anyway.  There seemed to be a LOT of potential responses that included rain, so I made sure the code would loop through and check for any of them.  I didn’t use them, but I also picked out the responses that related to Snowy weather as well.  

I also used an alternative method for the sending a text.  Somewhat tangentially related, a few months ago, I played, most of this little Programming Practice game called “TwilioQuest”, which is put out by Twilio.  I skipped the API portion of that entirely.  It seems that because I created my account while using a VPN, it became instantly locked.  I decided it wasn’t worth the hassle of unlocking it at the time, and it’s come up again for the exercises in this class.  

Fortunately, I can’t just send text messages by email.  Specifically, sending to (PhoneNumber)@txt.att.net will send an email to that number, on AT&T.  I am pretty sure this works on other carriers, but the to domain is of course going to be different.  The easiest way to find this is to send a “text” to an email address, since the phone number will be the “From” address.

In the end, I don’t really WANT texts anyway, so If I use this, I’ll just set it to send me an email instead anyway.  In fact, going forward, for these projects, I plan to just omit the Twilio/Text part and substitute in a regular email.  I just, prefer those. I even broke out my emailing code into it’s own class, which has been extremely useful for follow up projects since I can just drop that code into a new project, import it, then make a “Mailer” which I can call with the text of the message to send emails.

Day 36 – Stock Trading News Alert App

Just a more complex version of the “APIs with Authentication” as well as this lesson’s first “Do it all on your own” project with bare bones instructions.  It also involves two APIs, one for the Stock Prices and one for News Stories.

The end project, if a tracked stock price changes more than 5% up or down from yesterday and the day before yesterday, look up the top news stories about that stock, and email them to the user (originally text).  The overall project wasn’t that complicated, though I did make mine a bit more complicated than it needed to be.  Specifically, for the Stock Data, I created a function that accounts for the weekends when calculating yesterday and the day before yesterday.  It wasn’t hard, but, I guess the API data essentially already does this if you just read in sequence instead of by date.  

Oh well.  Both methods work fine and I used the dates in the News Story algorithm.

i also converted the whole system to work in OOP, so I could create several “Stock” classes for several companies, which were cataloged in an array and it would cycle through each one, maybe on a Cron Job and oh shit never-mind, the free version of the stock API is extremely limited on calls per minute.

Also oh well.  I don’t really follow stocks that closely anyway.

Day 37 – Habit Tracking App

I went ahead and put this one down on my “List of programs to improve later”, specifically, add a GUI, maybe the ability to manage multiple habits.  It’s a neat idea and concept and I like the API backend it used.  The real “hold up” is that I kind of already use a pretty robust Habit Tracking App that also does moods, called Daylio. I’ve been using it for…  it says 1740 day is my streak, which is almost 5 years.  Note to self, make a Daylio Blog Post in about a few months.

This is straight habit tracking/making though, without the mood.  So it still may be useful for tracking quantities over just straight “ifs” like Daylio is tracking.

Day 38 – Fitness Tracking with Google Sheets

Similar to last lesson, I already have apps that do this, though I am pretty sure most of the point here is to learn how to use the Google Sheets API.  Which actually will be useful for me, because I already have a few older, jankey, programs I have written that use Google Sheets as a back end, but make POST requests through Google Forms.  Connecting directly would be way way cleaner.

The more interesting part was working with an API that does natural language processing for work outs.  I kept trying to feed it weird things and it did a good job of translating it into the sheet dump.  Like “I climbed Mount Everest for 50 minutes” was found as “Rock Climbing”.  It also filled in for “I ran a marathon”.  Which was interesting.  It seems to have some basic idea of lengths to use.

Day 39 and 40 – Flight Deal Finder Capstone Project

I skipped the Day 39/40 Project.  Unfortunately there aren’t even any videos to watch over, but there is code to look over, so I did that. I literally, never, every fly.  And I don’t see myself every really having any use for this.  My wife isn’t going to fly, for a variety of reasons.  The only way I might fly, is if my job required it, but that’s going to be covered by my job, through their own travel management website.

Also the API wanted my payment information.  I’m not super keen on that one, especially because it seemed to want to connect to a bank account and not just some throw away CC number or an easily revoked Paypal connection.  

I updated the missing IATA Codes in the Google Sheet using Sheetly, and it’s PUT request API, which was the main “actually new” bit here.  I didn’t have the API for getting real IATA codes (see above) so I just took the first three letters for each city, upper cased them, and had the API put them into the sheet.

Also, Sheety has a limit on it’s free tier of 200 calls per month, and I’ve probably already used about half of them just testing the IATA Codes and the previous day’s code. Looking through the comments, it seems like everyone kind of disliked this project.

And this feels like a good breaking point for this section’s post.  The “Intermediate+” section isn’t done, but the next few lessons switch to a general over view of the web and HTML, before getting into other APIs.  I expect these next few lessons to go by quickly as well.  I am already well versed in HTML/PHP/CSS/etc, and there don’t really seem to be projects associated with the lessons.  I do plan to watch through them (mostly) to see if there is anything I can glean from them.
