After a drush upgrade from 8.4.2 to 8.4.4, my site went down with "The website encountered an unexpected error. Please try again later." error, and the error log is filling up with this message:

Uncaught PHP Exception Drupal\Core\Field\FieldException: "Attempt to create a field storage without a field name." at /var/www/mysite.com/htdocs/core/modules/field/src/Entity/FieldStorageConfig.php line 246

Drush couldn't clear caches (the above error popped up). I tried everything I could think of, including:

These instructions are written for Adobe Acrobat X, which even as of this writing is no longer supported by Adobe. Future editions of Acrobat will likely not work exactly this way.

Major Steps

There are two major steps to set up a digital signature in Adobe Acrobat:

1. Get a Digital ID
2. Create the Signature (appearance) based on that Digital ID

Once you have it set up, it's easy/quick to sign documents with your ID.

In Python3's pymssql library, the following error can crop up, and I found it to be a little misleading:

A script that ran happily for about a year suddenly stopped working last week. From the stack trace, it was apparent that the script was stumbling on Python's smtplib>sendmail command. Here's the error:

OSError: [WinError 10013] An attempt was made to access a socket in a way forbidden by its access permissions

The offending code:

This script tracks of Bitcoin's current USD price and displays it along with the price's "trend" since the script started running. The main part of the idea was borrowed heavily from this Stack Exchange article. It takes advantage of the coindesk API for getting current price information.

Sure, it's not a fancy line graph, but it's got ASCII-art up/down arrows!

Here's an example screenshot:

if you frequently have to toggle between two network adapters in Windows, it can become a hassle to keep opening the Control Panel widget, right-click, disable/enable adapter, etc. For example, you may want to turn off your wired connection and connect to wifi, then switch back to wired, etc.

I find that I frequently (many times daily) have to send files as email attachments. Depending on the task, the files can be located in a half-dozen or so places on the Windows file system. I found myself browsing (from Outlook's "Attach File" function) to my Documents, Downloads, Desktop, or one of several network drives for the file I just saved there a few seconds ago.

When installing a Python 3 package with Pip, if the package to be installed calls for a dependency that is outdated or otherwise not available, you can get a local copy of the module, change its dependency lists, then install it from the local source.

This will likely be no big deal for the Python wizards out there, but it was a pretty nice victory for me, so I thought I'd better share in case someone else has the same trouble.

I was attempting to install the lastpass-python module:

In a Drupal view, I have a button in place that allows the user to export the current view to an Excel (XLS) download (utilizing views_data_export module functionality). That download is expected to be around 3,500 rows, with 39 columns. I just noticed that trying to hit that button for the download results in (almost exactly 30 seconds later) an error I hadn't seen before: "Server Hangup".

I recently had to upgrade a Windows IIS Server running PHP 5.5 to PHP 7.1.1. I ran across this excellent blog post which got me 99% of the way through the process.

Some things I had to do additionally/differently:

I've found this tool to be very powerful and helpful...and I almost couldn't find it again after recently upgrading to a new computer. To prevent future heartburn, I'll document it here.

From the csvkit web site:

csvkit is a suite of command-line tools for converting to and working with CSV, the king of tabular file formats.

This post outlines a method I came up with to use a single AutoHotKey script to auto-load any number of scripts in a sub-folder. It also allows every script to have its own autoexec section, and to hook into a timer for event-type functionality.

AutoHotKey scripts that are 'persistent' need to be loaded into memory by Windows just one time. If you have several of them to load, you can get them all individually, but you end up with a system tray full of little green 'H' icons.

AutoHotKey is a powerful Windows automation tool, capable of doing pretty much anything you could do yourself on your PC. I have a number of scripts I run regularly (or always have running) to speed up my work and/or make it more accurate and efficient.

One of my favorite scripts responds to the key combination of Ctrl-Alt-0 (that's a zero). When I press that combo, a couple things happen:

1) First, the script checks to see if the machine is connected to WiFi, and if so, grabs the name of the WiFi's SSID.

I haven't found a way to make my email 'groups' from Outlook available on a mobile device (Android phone). I've tried several email clients, but none of them brings in the groups I use frequently in Outlook.

Recently, I came up with a workaround, using Outlook rules. Essentially, I can set up a rule with the following criteria:

• Sent from my account

• Sent to my account

  I almost never send mail to myself, so this works. If you routinely cc: yourself, you may need to be careful here.

Background

Network drives allow multiple users on the same network to have acccess to the shared folders/files. However, if you have two different sets of network drives (at work and at home, for example), it can be a hassle to manually map drives when your computer 'resumes' on the new network.
