pinboard | threadsafe way to publish data | Storage library

This isn't a general gripe about the bloat of Android apps nowadays^*, but a very specific question:

If you install Android Studio 2.3.3 and create the "Hello world" sample app (as described in the Building your first app official tutorial), then build a release APK, the resulting file is 825KB (I tested this on Linux, but I suspect the output is the same on other OSes).

I've already enabled ProGuard and there are no images or other resources.

What goes in that APK by default?

Why?

How can that bloat be taken out?

By comparison, in 2013 a Hello World app was under 10Kb.

_{* I remember when decent fully-functional apps were a few hundred KBs, and by comparison a PWA like Uber is 1% the size of the corresponding Android app}

Problem:
I am unable to successfully publish a non-monolithic script module to my local PowerShell Gallery when using PowerShell 5.1 and my module contains 7 or more functions. Publishes fine with 6 or less functions.

Example: FunctionsToExport = 'Get-Test1', 'Get-Test2 ', 'Get-Test3', 'Get-Test4', 'Get-Test5', 'Get-Test6', 'Get-Test7'

The publish always hangs at 'VERBOSE: Performing the operation "Publish-Module" on target…', but never completes.

I am not seeing any errors, so I am not sure why it is hanging.

What does work:
I can successfully publish my non-monolithic script module to my local PowerShell Gallery when it contains 6 or less functions.

Example: FunctionsToExport = 'Get-Test1', 'Get-Test2 ', 'Get-Test3', 'Get-Test4', 'Get-Test5', 'Get-Test6'

This works fine: VERBOSE: Successfully published module…

If I simply add one more function and update the manifest, I can no longer publish without it hanging again at the same place.

I am pretty sure I am missing a step, but I am having trouble figuring out what I missed.

I am learning the non-monolithic script module design from Mike F Robbins by reading his blog posts and watching his presentations. The gist of this design is each function is in a separate PS1 file that is dot sourced from the PSM1 file.

Summary of how I build my script modules:

• Create new script module scaffolding using custom Plaster template.
• Add functions to the folder named Public.
• Update module version and FunctionsToExport section in manifest.
• Use PsDeploy or Publish-Module to deploy to a local PowerShell Gallery.
• The local PowerShell Gallery is just a folder on my data drive G:\JnPowerShellGallery.

This is how I am publishing my module to my local PSGallery.

So I wrote a code to make 4 photos (or more) be responsive (Pinboard like) but I can't figure out how to make the photos be random.

Example: You visit the page and you see img A: B: C :D Then when you refresh the page there is a different set of images. I know there is plenty of tutorials to randomize photos but I haven't found anything with the pinboard like design that I created.

Could really use some help in understanding what code I need to add to make the photos change with each page refresh instead of always showing the same photos.

HERES MY CODE:

In an effort to hone my python and Spark GraphX skills, I have been trying to build a graph of Pinboard users and bookmarks. In order to do so, I scrape Pinboard bookmarks recursively in the following fashion:

1. Start with a user and scrape all bookmarks
2. For each bookmark, identified by a url_slug, find all users that have also saved the same bookmark.
3. For each user from step 2, repeat the process (go to 1, ...)

Despite having tried suggestions from several threads here (including using Rules), when I try to implement this logic, I get the following error:

ERROR: Spider must return Request, BaseItem, dict or None, got 'generator'

which I strongly suspect has to do with this mix of yield/return in my code.

Here a quick description of my code:

My main parse method finds all bookmark items for one user (also following any previous pages with bookmarks of the same user) and yields the parse_bookmark method to scrape these bookmarks.

Trying to reproduce (in the simplest way possible) Maciej Cegłowski's http://pinboard.in; instead of Links and Tags, I have Books and Tags. Every Book can be tagged with any number of Tag's, and a Tag is associated with many Book's.

In an attempt to teach myself how to program, I'm making a little web app (Flask, SQLAlchemy, Jijna) to display all the books I've ever ordered from Amazon.

In the "barest bones" possible way, I'm trying to learn how to replicate http://pinboard.in—that's my paragon; Maciej Cegłowski is a straight G ... I have no idea how his site runs so goddamn fast: I can load 160 bookmark entries—all with associated tags—in, I dunno, 500 ms? ... which is why I know I am doing something terribly, terribly wrong, as is discussed below. (If I could, I would just pay him to tutor me. lulz.)

In any case, I created a many-to-many relationship between my books Class and my tag Class such that a user can (1) click on a book and see all its tags, as well as (2) click on a tag and see all associated books. Here is my table architecture:

Here is the code for the relationship between the two Classes:
