ThinkPad Wired USB Keyboard with TrackPoint, 0B47190: Disassembly and Cleaning

A friend has this Thinkpad/Lenovo keyboard for a long time, but the right mouse button was becoming erratic. We decided to disassemble and clean it and try to fix the right mouse button. on the back of the keyboard, CEM-2015-05-29 Rev W02 Fru PIN 03X8715

Prying the Clamshell Apart
Turning the keyboard over there are rubber pads on each corner and one in the middle. These do not have screws underneath, so disregard them. This is a plastic clamshell. I used a credit card to pry open the clamshell from the USB port, and then used a flat head screwdriver to pry the two halves part. The front bezel comes apart easily.

I enjoy taking apart machines, especially well engineered and built machines. How do you know if a piece of engineering is well built? You take it apart and see for yourself. This is a friend’s Philips System One Continuous positive airway pressure (CPAP) machine that, after 6 years of daily use, was replaced by a better model. Here’s how to take it apart.

Overall the machine is made of thick ABS. The air intake has both a foam and paper filter. Surrounding the motor is a silicone liner that was very clean, even after 6 years. There are air gaskets that seal in the air.

Working with a Tyrant: Governing from Within

This New York Times editorial is gutsy and calls out Donald Trump. It is well overdue. The lack of truth, the fabricated truth, no truth, all adds up to either you disregard reality and go Trump, or you question how this administration can come to pass.

All ages have their tyrants. They are psychopaths that can be charismatic and draw followers into his fold. I worked for one but they quickly removed me. You either believe or they chew you up and spit you out. This is where you find out if you have the backbone to stand up for who you believe you are and how you were brought up, or fold into the morass.

It is 2018 September 05 and Toronto is 34C!

Usually Toronto is moderately warm in June and hot in July and August. By the time September rolls around the weather cools down considerably. This was untrue this summer, where we have had a very hot June through to August. And today, on 2018 September 05 we are experiencing yet another super hot day. Wow. At least our PM2.5 air quality, at 55 moderate is not too terrible.

Hot Toronto 34C weather 2018 Sept 05. Very unusual

Toronto Air Quality is 55, still at Moderate. This is good.

Saving PSB Images from Chinese QQ QZone Wall

Chinese QQ QZone's photo image display javascript gets in the way of saving large images

Chinese QQ QZone’s photo image display javascript gets in the way of saving large images

On Chinese QQ QZone people have walls similar to FB. QZone uses an image display script in your browser. If the image is large when you right click and you can save the image as .PSB or .JPG, but it will not render in your browser, as .PSB is an unknown file type. I believe QQ’s javascript manipulated the image so you can zoom and move around, but this gets in the way if you want to see the original pic and zoom for yourself.

WordPress Trackback Spam Technique for Content Spamming

Recently I have been observing a different WordPress spam technique that uses WP trackbacks. This technique has some interesting characteristics that are unlike other types of spam, so my usual clues as to origin and banning method did not work. Fortunately this technique also has some unique characteristics that can be used to ban them. Fortunately.

WordPress Trackbacks
When one WP site links to another WP site, the WP sites communicate with each other using a method called trackbacks. The first site sends a trackback request to the second site. The second site posts the trackback as a special comment, which invites the user to click through to the first site. These trackbacks are automated, making it convenient for both sites.

Using the QQ QZone: Hints and Tips

I use the QQ messenger program from Tencent in China. While its big brother WeChat has a very broad ecosystem, QQ is much smaller and has limited function. As I wish to limit such a program to only messaging people in China, QQ fits the bill for me. Both QQ and Wechat are standalone programs that can run on Windows, Mac or Android. There is no version for Linux.

Both QQ and WeChat have a huge following in China. QQ has 805.5 million users, while WeChat has 1,040 million monthly active users (MAU). As of the second quarter of 2018, Facebook had 2.23 billion monthly active users [worldwide].

Ontario G1 road test vs Class G2 road test: Are they the same?

Little Weed is of the age where he is considering getting his G1 license, or Learner’s Permit. What is confusing is the Ontario Ministry of Transportation terminology. In fact they seem to be both the same.

The minimum practice period for G1 drivers before they can take the G1 road test is :

12 Months Without Driver’s Training : You are not eligible to take the G1 road test until 12 months after you have passed your written test unless you have taken an approved drivers ed course…

Dried Achiote Paste: How to Break It Down Back to Powder

Achiote paste: A unique Mexican flavour, but if it dries to a brick, is very difficult to break back down to a paste.

Achiote paste: A unique Mexican flavour, but if it dries to a brick, is very difficult to break back down to a paste.

Big Weed had purchased this in California, as we do not have access to this here in Toronto. Achiote paste has a very unusual taste which I like. As I only used a half of the small pack I did not know to tightly wrap it so that it did not dry out. The result was a brick that was as hard as rock. Instead of wasting the achiote brick, which I cannot buy here in Toronto, I decided to try to break it down back to smaller chunks of near powder. This was more difficult than I thought.
