Ozone Hole and Refridgerators

December 19, 2020

Getting a new refrigerator this week, with the delivery people taking away our old fridge (See Note 1) caused me to to think about the “ozone hole” problem.

The delivery people were firm in their belief that the gasses in the refrigerators now were very dangerous and they have special procedures to handle the old refrigerator. That’s ok, they said, because it fixed the ozone “hole”.

Reading the scientific literature (which I’m sure the delivery people were unaware of) I think the jury is still out about the impact of eliminating chlorofluorocarbons (CFCs).

So here’s how I see it:

1. They banned chlorofluorocarbons with the “hope” of eliminating the ozone hole
2. The new chemicals are more dangerous if released and are less efficient in cooling (causing a net increase in energy use to overcome the loss of efficiently).
3. Since the new chemicals are dangerous they implemented strict controls on handling the new chemicals. Surely these controls and systems design are not without significant cost but we’ll ignore that and just assume some cost.

So … why did we not invest the same money (whatever that cost) to build handling systems to control release of chlorofluorocarbons from refrigerators and retain this “better” chemical for refrigerators in the spirit of reducing energy consumption? Was this never considered?

Somehow or another I doubt it as the people wanting the sell the new chemicals had a different objective in mine. Just wondering.

Note 1. Economically not possible to repair the old one. We did not take out an extended warranty on the fridge 2 years ago as it was pretty expensive and I know vendors do not lose money on these warranties. Since we didn’t have an extended warranty, and the base warranty was only 1 year old, the vendor wanted a LOT of money to just look at it, and then parts and labor would be “extra”. So … we bought a new one from a new and more reputable vendor.

DEVONthink and Hazel

December 4, 2020

The purpose of this document is to outline in general terms how we use capabilities of Hazel and DEVONthink, in tandem, to automate the process of getting files into DEVONthink and then processed (where possible and implemented).  

We use Hazel for what Hazel is good at. We don’t try to make DEVONthink do what Hazel does well. We let DEVONthink do things related to DEVONthink.

There is no use of Apple Script in this process. Certainly Apple Script could be used, but because Apple Script is OSX-specific and that I can’t be bothered learning yet another computer language I avoid Apple Script when it’s not really needed to meet my needs. Other people’s skills and needs are perhaps different. 

Global Inbox

DEVONthink has a so-called “Global Inbox” folder to which it looks to automatically import into the Global Inbox when files appear there.

This screen shot from Page 8 of User Manual for DEVONthink 3.6.1.  All other references to the DEVONthink User Manual is to this document available from



Page 128 describes how to turn this on and create this folder.  This folder is buried in the file system, but is displayed in OSX’s Finder simply as “Inbox” after it is installed via the “Install Add-Ons” menu in DEVONthink.  The Global Inbox folder is located in:

/Users/XXX/Library/Application Support/DEVONthink 3/Inbox

Where XXX is the user’s login name.

Anything dropped into this folder, manually or by automated process, gets eventually imported into DEVONthink.

For more information on the Global Inbox, see the DEVONthink User Manual.

Making the Global Inbox Work

As mentioned above, the Global Inbox Folder in the Finder’s sidebar and is simply “Inbox”.  Sometimes I forget that that folder means when I want to put a file there for automatic import into DEVONthink.  

I also want to make it easy for me to add files to DEVONthink from whatever device (IOS or OSX) I may be using. This DEVONthink folder resides on one machine and not easily accessible by other devices. 

This is not a full explanation of how we use Hazel, DEVONthink, or other apps we have in our workflow for reading, learning, and writing (occasionally).

To make this happen I use Dropbox which runs on all my devices to sync files.  Most all the files and folders that I work on are in the Dropbox folder so it’s a “universal” file location for me accessible by all devices.  Dropbox automatically takes care of the synchronisation of all so-called Dropbox files across all of my devices.  

For sure other synchronisation products and applications could be used, but I’ve not bothered trying as Dropbox works well.

In the Dropbox folder I create a special folder called “2DEVONthink”.  See that folder in Finder, along with “Inbox” in the following screen shot of my Finder.  I put a “2” at the front of the folder so that it shows up near the top of an alphabetic list of folders (in Finder in OSX or Files in IOS), and I put “DEVONthink” in the name to make it be what it is. I did not add “Inbox” to the folder name as it makes it too long and redundant anyway.


Anything dropped into this folder, manually or by automated process, gets eventually imported into DEVONthink.

Now how do we make it useful?  We use Hazel (https://www.noodlesoft.com) quite a lot. From their User Manual:

Hazel Overview

We setup Hazel to “watch” the “2DEVONthink” folder and when anything appears it moves it into the designated DEVONthink Global Inbox folder on that machine (see “Global Inbox”).

By making a Hazel rule (which runs on a desktop iMac which is usually always running (or sleeping) and connected to the internal and external network, it can act automatically on my behalf to move an incoming file (via Dropbox) into the DEVONthink folder, and then if DEVONthink running, or when it does run, it imports all the files it sees in it’s Global Inbox folder.

Hazel 2DEVONthink Rule

Using 2DEVONthink in Real Life

This folder becomes the one place I put all files that are destined to DEVONthink.  I just drag and drop from where they are, or “File/Save As …”.  There are of course many ways to get files into DEVONthink which are well covered starting on Page 48 of the DEVONthink User Manual. 

What’s nice about using this approach is that once DEVONthink “imports” the file into it’s Global Inbox, then we can use DEVONthink’s Rule Engine to automatically do things for me.  All “incoming” with this method will be trigger the Rule Engine’s “Perform the following actions” then picking “Import”.

Related: Pre-analysis on Incoming

For some files I like to give them good “stand-alone” names which succinctly describe the contents. Files have to “stand-alone” regardless of what file folder, DEVONthink “group”, or whatever they reside in. I use Hazel to pre-process some of these rules.

Look again at the Finder Window in “Making the Global Inbox Work” and notice the folder “Scanner Input”. 

This is the folder to which I direct output from Scanner and where I drag/drop files which I want handled like scanned files, e.g bank statements, invoices, bills, etc. Things that I can figure out the pattern based on content and then adjust the file name before sending on to DEVONthink. 

Again Hazel comes into it’s own here as it has very sophisticated technology handle files based on user-defined rules.

We setup (numerous) rules watching “Scanner Output” for files matching patterns. Once the pattern is recognised, then we direct the file to it’s intended destination.Often that destination is DEVONthink, so we simply tell Hazel to move the file into the 2DEVONthink folder. Some of the rules direct files to another folder, and some of those folders are “indexed” by DEVONThink.

RMSLtd Rule

Notice in the above example we are using Hazel’s capability recognise date formats, assign dates to variable names, text into variable names, and then use those variables in the actions.  See the Hazel User manual for more information on how to do that.

In summary, we use Hazel for what Hazel is good at. We don’t try to make DEVONthink do what Hazel does well.  We let DEVONthink do things related to DEVONthink.

Types of Rules used “On Import”

Once the file hits DEVONthink’s Global Inbox, we have a number of rules setup to process those files. DEVONthink has some sort of queuing process setup to do things in order and one at a time. We don’t need to “schedule” these rules to fire at intervals or at any particular time. We just tell DEVONthink to do things “on import” trigger.

Some of the rules we have setup to fire “on import” are:

  • Convert PNG and JPG files into one-page PDFs
  • Convert all HTML files into multi-page PDFs
  • Convert Web Archive files into PDF
  • OCR anything not already OCR’ed
  • Classify (this one works better and better as time goes on)


This document was composed using Scrivener (https://www.literatureandlatte.com/scrivener/overview), my favorite tool for writing. It was compiled into a simple PDF format. The Scrivener files are NOT in DEVONthink but in the folder where I keep all the Scrivener writing projects. The “finished” PDF is stored in DEVONthink.

The “Loonies” have taken over

Big Hat Tip to Paul Homewood at “Not a Lot of People Know that”, but see his article about the “Climate and Ecological Emergency Bill” in Parliament. https://notalotofpeopleknowthat.wordpress.com/2020/09/06/mps-table-climate-emergency-bill/

Another easily-predicted but suicidal action is the how the government and power companies are hoping to use smart meters to turn over supply of electricity. Starting with Central Heating and car charging, but when will it stop. Why not instead work to build a reliable electrical power supply system. https://www.msn.com/en-gb/money/other/government-mulls-emergency-measures-that-would-enable-smart-meters-used-to-switch-off-your-electricity-without-warning-or-compensation/ar-BB198Jlb and elsewhere.

Thoughts on being Paperless

April 17, 2020

My first draft of this was a reply on the Mac Power Users forum. I thought I would post more permanently here.

How you get to paper-less has to suit what you do, can do, and need to do. You can start and achieve paperless without a lot of messing with fancy computer tools. Exploit the tools to your benefit when the need and value is clear.

I’ve been pretty much paperless for years and in a nutshell, I would offer the following:

I used to use and recommend Fujitsu scanners and software. I abandoned the two perfectly working scanners I had because Fujitsu for Mac OSX Catalina changed the licensing model and didn’t make the software compatible with my hardware. Shame on them. I moved to a Brother ADS-1700w with automatic document feeder. I also occasionally use a flat-bed scanner which is part of my Epson WF-2750 printer.

For me, tagging is probably a waste of time. Feels good to tag, and I do it; but I never use them.

Having a deep folder structure is probably also a waste of time. Feels good to have a structure, and I probably over-do it. Deep folder hierarchy has deep history when everything paper involving many clerks and admin staff with file cabinets, drawers, and filing folders in the drawers. Probably started by the project team that built the pyramids! Those days gone. Simple folder structure and then rely on that and computer navigation (Finder) and search (Spotlight et. al.) to find stuff.

Remember that the containing folders are not “sticky” to a document if the folder name contains important information to identify the file. File names are the best you have to label the document and remain unchanged, normally. When files move around and if they depend on the folder names above to describe the document, then key information is lost. I use Hazel to help with naming files, but sometimes I name/rename manually. As I’ve used Hazel for years, I of course have some complex rules. Make Hazel shine is fun. Notionally I name all files something like: [Scan or Incoming Date] [Identifier] [Description including document date if appropriate].pdf. PDFs are OCR’d. I rely on the computer’s search to find things more than hunting through folder structure.

  • [Scan or Incoming date] is YYYYMMDDHHMMSS as can’t depend on file system dates “sticking”. This format is sortable.
  • [Identifier] is normally the same as the folder targets (to help me or Hazel move, and may include initials of person if personal
  • [Description] as it says. Vendor, what it is, for what, etc. If a bill/invoice, I’ll include the date in readable format, e.g. 4 June 2019 or something. Be descriptive. Hazel can be setup to extract all that, but easy to go over the top.

I’ve learned that a few top-level folders is best. I minimise use of subfolders for reasons as described above.

  • ~Personal/ with a subfolder for each person in the family with stuff pertinent to them. Subfolders by person are as appropriate. Some of these subfolders by person are shared across network with that person.
  • ~Finance/ with a subfolder for each year. I dump everything for that year in the relevant year folder. No other subfolders (relying on file name to distinguish the files)
  • ~Interesting/ with a few subfolders of interest area.

I have a few more top-level folders which have emerged over the years but too detailed to explain here. I hope you get the gist.

The Finance and Interesting documents are actually now imported fully in to DEVONthink databases (one for each). A third DEVONthink database is “Personal” which is mostly indexed back to the ~Personal/ folder–I do that so that I can keep sharing with the family members secure and easy. they don’t use (yet) DEVONthink. I’ll use DEVONthink for searching/finding/etc.

DEVONthink will use the tags that were assigned into the OSX file system, but yet again, i find that while I do it, I never use them. Gotta stop, I think. DEVONthink’s structure (Groups, Smart Groups, etc.) is great.

You of course don’t need to use DEVONthink, especially at start. If you chose to get there, you can drag and drop your files to import (trivially easy), or you can index pointers back to the files still residing in the file system. All this described fully in DEVONthink’s terrific manual.

Files inside DEVONthink are still in native format and not proprietary as other applications. Important, I think.

And, perhaps most importantly, remember and be cognisant of:

  • Some information is private and needs to be kept confidential and secure. To what extent you do that depends on the nature of the information.
  • make sure you have robust backup regimes. Consider having offsite backup also somehow or another.

Modelling …. Humm.

April 15, 2020

Important and insightful article by John Nolte:


“So when these proven frauds try to destroy your standard of living and centralize their political power using their global cooling global warming climate change or whatever the hell these proven frauds are calling it today, models, remember how terrible the “expert” coronavirus models are, and remember that the coronavirus “experts” had a whole lot more information to work with for their models than the modelers predicting global cooling global warming climate change or whatever the hell these proven frauds are calling it today.”

Modelling the Virus. Oh dear.

March 30, 2020

Call it “Wuhan”, “Chinese Corona”, or COVID-19 … whatever.

Neil Ferguson, the “scientist” to used his model to advise UK government (in the news) is now admitting the facts about the ‘C’ code he wrote 13+ years ago (he calls it “thousands of lines of undocumented C”). Oh gosh. C is pretty much the worst thing to use for this sort of thing and being undocumented, and probably unvalidated is scary. It’s alright though. Don’t worry. He’s turned the Code over to Microsoft who is re-writing it and will put a “web front-end on it” .

I feel better already.

Ocean Heating Cause Maybe Not by CO2

March 28, 2020

A very interesting article “Geologic Heat Linked To East Coast Ocean Warming Trend” which shows NOAA data that supports the view that there are other significant sources of heat that warm the oceans besides atmospheric CO2.
