I have 2 monitors on my laptop computer. It’s nice. Here’s info about my second monitor:

– AOC 15.6″ USB powered monitor
– ClickMonitorDDC
– Displaylink driver

I set up ClickMonitorDDC so I could change the brightness of both monitors easily. Info here. I also set it up to change the volume easily.

I had an, apparently common problem where sometimes the screen would restart repeatedly. To fix it, I disabled “USB Selective Suspend” and upgraded to the December 2019 Displaylink drivers. That fixed it. There’s more tips on fixing that problem here in case my fix doesn’t do it.

I bought 2 of those USB-powered monitors so I don’t have to drag it from home to work each day. That was nice.

I just got an oscilloscope and the manual mentioned “Locating Sleeve: Using locating sleeve could ensure the stability and reliability of the tip exposed to the test point.” Say what?

Here is what a locating sleeve is for. If you need to carefully touch just one point on a PCB, you can take off the tip of your probe off, that is the tip with the spring loaded hook, and then attach the locating sleeve. Now it will be easier to touch just what you are intending to.

These instructions work! Hurray! I tried a while back and it didn’t work.

This tip came from my friend Tim A. He added, “I found that it seemed to stop me downloading the apks directly, so I put them on the SD card and installed them from there.”

If you use Cricket Wireless, you may have found, like me, that Cricket Visual Voicemail sucks. Here’s how to change to using Google Voice voicemail.

Step 1: Get free a Google Voice account with a new phone number

Step 2: Set up conditional call forwarding like so:

**004*[your google voice number]#

Step 3: Have someone call you and the call should be answered by your google voice. Rejoice in the non-suckyness!

You can disable this forwarding with #004#

You can read more about conditional call forwarding for GSM phones here

Update 11-6-19: On the Google Pixel 2, I was unable to use the **004* code. It threw an error. So I did what a few websites recommended: Put the SIM card into another phone, type in the code above, put the SIM card back in your phone. Done!

Why do I say the Cricket Visual Voicemail Android app sucks?

• I have to push most buttons twice for it to work (sounds crazy? it is!)
• When I start playing a voicemail, the first 3 seconds play and then it stops. Hitting play (twice) restarts it as long as I’ve waited the magically determined amount of time. It’s crazymaking like having a big piece of lint under one of my keys!
• It often doesn’t transcribe my messages
• I’ve had these exact same problems for 3 years and 2 phones

TL;DNR: I was getting 50,000 spam email bounces per day. I enabled SPF, DMARC, and DKIM. I made an email filter at Dreamhost to stop the email forwarding madness from Dreamhost to my Gmail account. Problem solved! (for now)

Tens of thousands of people have been getting spam claiming to be from Lee.org. (Update 8-4-18: HUNDREDS of thousands 🙁 ) First, I’m sorry about that! Second, it’s not actually coming from me. Third, I documented below how you too can stop spam from being spoofed from your domain.

I was alerted to this when I got 20,000 email bounces last week from a letter sent in my name. That one started:

From: Mr-Williams <lee@lee dat org>
Subject: Re: Your Outstanding Bill Payment notification
How are you doing today? I am Pleased to inform you that we have made arrangement with bank of America to release your payment sum of $10.3 Million dollars…

I realized that my (geekspeak alert!) SPF record was incomplete. So bad actors were able to pretend to be me and send zillions of spams in my name. I had incorrectly set my SPF record in my DNS to:
TXT v=spf1 include:netblocks.dreamhost.com
but it should have been set to:
TXT v=spf1 include:netblocks.dreamhost.com -all

Without the “-all”, SPF wasn’t working to stop spam in my name!

Here’s what one of the spam email headers looked like:

Authentication-Results: spf=neutral (sender IP is 201.162.82.32 (In Brazil, definitely not from my mail host!!!))
smtp.mailfrom=lee.org; hotmail.com; dkim=none (message not signed)
header.d=none;hotmail.com; dmarc=none action=none header.from=lee.org;
Received-SPF: Neutral (protection.outlook.com: 201.162.82.32 is neither
permitted nor denied by domain of lee.org)

MXToolbox is what keyed me in to what was going wrong. Thanks!

And thanks to Shehz for the helpful comment!

Update 8-3-18
I also added a DMARC record to my DNS
It’s a TXT record under lee.org that looks like so:
_dmarc TXT v=DMARC1; p=quarantine; ruf=mailto:[myDMARCemailaddress]@lee.org; rua=mailto:[myDMARCemailaddress]@lee.org; sp=n
one; ri=86400
So now email receivers know definitively what to do with spam coming to them from lee.org. And I get a report of when a bounce happens. I initially set p to “none” and got a few correct DMARC reports. Now it’s “quarantine” and in a little while I’ll set it to “reject”.

Update 8-3-18 #2
With DMARC enabled, I’m getting fifteen hundred reports a day telling me that spam “from” lee.org is being blocked. Ugh, sorry world! That tide is stopping now!

I got help with DMARC from these sites:
* https://dmarc.org/
* https://mxtoolbox.com/SuperTool.aspx?action=dmarc%3alee.org&run=toolpage

Update 8-22-18
I averaged 700 DMARC spam reports per day for the last 7 days.

Update 10-19-19 I got rid of the mailto: fields in my DMARC entry. I’m tired of getting kinda-pointless DMARC messages.

Update 10-18-18

Dreamhost shut off my email temporarily twice recently because the quantity of spams being forwarded from my Dreamhost lee.org account to my Gmail account were getting the better of them. Ugh. Here was the suggestion from Toby at Dreamhost:

SPF and DKIM records only help if the receiving server checks them. I would advise not to forward to gmail as this causes server load issues for everyone else on the server if you do run into further problems with this. You can configure your Gmail client to retrieve your email directly from Dreamhost’s server using POP3, and discontinue the use of your forwarder.

You’ll get all the benefits of Google SPAM filter as well, and this will be functionally equivalent to your current configuration. For more information on how to set up the Google side of things, please refer to the following article:

https://help.dreamhost.com/hc/en-us/articles/214870568-How-to-check-your-DreamHost-email-at-Google

Additionally you can setup filtering to filter out these spam message so
they don’t forward nor clog up your email box.

I set up POP3 fetching and created some custom filters. I noticed that Gmail fetches about 200 emails per grab and it runs every 5 minutes or so. That means if I’m getting a lot of spam, Gmail won’t be able to keep up with fetching the mail! I just tested this and… OMG I opened the floodgates and started getting 250 email bounced PER MINUTE! It is no freaking wonder why Dreamhost turned off my email forwarding for a while!! Here’s a snapshot of Gmail and Dreamhost failing to keep up with the full force of spam with the spam floodgates wide open.

I deleted my spam folder with 1,500 emails and closed the floodgates by putting some filters in place at Dreamhost. But even 15 minutes later, old spams were still slowly trickling into the spam folder… Looking at the headers, it’s hard to tell if Dreamhost started choking/rate limiting or Gmail was choking/rate limiting.

I turned off POP3 mail fetch and left the mail filters in place. All is well now!

It was as simple as setting Dreamhost Panel | Mail | Message Filters | to “First, delete emails with [bad actor] in the body and then stop.”

Autohotkey is mind bogglingly useful! Autohotkey is a free, open source Windows program that lets you do simple and complicated scripting with keyboard commands. I’ve been using it since about 2001. I use it a zillion times a day. I couldn’t imagine not having it.

Some things you can do with it:
– Have a second copy-paste clipboard
– Do a “paste” and strip out the formatting
– type often used strings like addresses, phone numbers, and email signatures with just a few strokes.
– make a window on your computer to be always on top of the other windows
– start a favorite program (Chrome, Word, Calc, whatever) with a single keystroke
– Type today’s date with a single keystroke

I’ve set it up to do about 50 commands. If you want to do things on the computer faster and easier, you might want to use it too. Just download Autohotkey and put some of the scripts I have below in your setting file. There’s a bunch of ways to do that, here is a tutorial.

Here is my settings file. Just look at the first line of each script to see what it does.
