Change broken sun visor clip snap retainer holder for 1998, 1999, 2000, 2001, or 2002 Toyota Corolla

This is a pretty easy DIY fix.  All you need is a standard phillips head screwdriver.  If your visor clip still holds the visor, but is kind of broken where it easily comes un-snapped, pick up something like this from eBay for well under $10:

Unscrew the old one.  Pull the old one out.  You might have tug at it a little hard.  I even used a flathead screwdriver to pry a little of it off.  It will pop off eventually, and then you can easily install the new one.

Installing PhpPgAdmin on Fedora

Installation

Install postgresql and apache httpd

Install PhpPgAdmin:

sudo yum install phpPgAdmin

pg_hba.conf

Modify the pg_hba.conf file and change the following line:

local   all             all                                     peer

to this

local   all             all                                     md5

This will allow a password to be entered when the PhpPgAdmin app tries to login to the postgresql server.

phpPgAdmin.conf

If you've installed phpPgAdmin on Fedora (or likely other Linuxes such as CentOS or RHEL), you'll need to modify the /etc/httpd/conf.d/phpPgAdmin.conf to open up access.  In the Apache 2.4 section, put only this line in:

Require all granted

Then restart the httpd web server.

Then try to login here: http://localhost/phpPgAdmin - you will use the same login and password that you use to login into postgresql with the psql command line utility.

How to get Nvidia Driver working on Fedora Linux 27

I had a few problems with this, so I thought I'd blog about it.  There's a new way to install the Nvidia driver on Fedora.  First, check if your laptop has the Optimus technology (hybrid graphics).  If so, disable it in the BIOS.  Then follow these instructions:

https://www.if-not-true-then-false.com/2015/fedora-nvidia-guide

When you finally get ready to test out if your Nvidia driver was successfully installed, you can run glxgears and check the frame rate.  You may have to turn off "Sync to VBlank" in the nvidia-settings (in "OpenGL Settings") first.

These instructions are needed to download (or create) a patched version of the NVIDIA installer, for newer kernels such as 5.x (e.g. 5.5 and 5.6).

How to play a DVD movie on Fedora 24

This probably works on newer Fedora versions too.  You might have problems with DVDs not playing, due to them being encrypted and Fedora not coming with the decryption software.  Here's how to get your DVD movie playing.

sudo su

dnf install https://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm

dnf install gstreamer1-{ffmpeg,libav,plugins-{good,ugly,bad{,-free,-nonfree}}} --setopt=strict=0

nf -y install --nogpgcheck http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm

dnf -y install gstreamer-ffmpeg gstreamer-plugins-base gstreamer-plugins-good gstreamer-plugins-good-extras gstreamer-plugins-bad gstreamer-plugins-ugly gstreamer-devel gstreamer-plugins-base-devel gstreamer1-libav gstreamer1-plugins-bad-freeworld gstreamer1-plugins-ugly

dnf -y install libdvdread libdvdnav lsdvd

sudo dnf -y install git autoconf automake libtool kaffeine

# Download and install libdvdcss

mkdir /path/to/anywhere

cd /path/to/anywhere

git clone https://code.videolan.org/videolan/libdvdcss.git

cd libdvdcss

autoreconf -i

./configure

make

sudo make install

Then start Kaffeine by pressing the Windows button on your keyboard, and searching for "Kaffeine". The DVD should start.

How to clear P0128 Check Engine Light (CEL) (coolant temperature below thermostat regulating temperature) on a 1999, 2000, 2001, or 2002 Toyota Corolla

Parts needed:

• Temperature sensor: http://www.ebay.com/itm/271937021784
• 19mm deep socket: http://www.homedepot.com/p/Husky-3-8-in-Drive-19-mm-6-Point-Metric-Deep-Socket-H3D6PDP19MM/202913533
• 10mm socket
• Mini flathead screwdriver

Do this:

1. Park car in a place where you don't mind a little coolant leaking out, or put a basin under your car
2. Pop hood
3. Disconnect battery  (Disconnect black/negative first)
4. Remove battery from car
5. Remove engine air filter and air filter console.  You don't have to completely remove the top of the air filter console.  You can just move it off to the side. See https://www.youtube.com/watch?v=sXUNb9fTeG8 - you might need to remove two black plastic cable straps/ties which you can do by sticking in a mini flathead screwdriver in the opposite side (from the bottom).  Be careful not to drop any 10mm bolts down the hole in the air filter console.  You can wrap it in aluminum foil if you don't trust yourself.
6. Use your hands to unclip the wiring from the old temperature sensor.  It might be a tight fit, but you should be able to get your fingers in there if your fingers aren't too fat.  Be careful not to break the sensor wirings.
7. Remove the temperature sensor using the 19mm deep socket.  I used a breaker bar.
8. Some coolant might leak out, so quickly hand-screw in the new temperature sensor into the engine and tighten with the 19mm deep socket.
9. Reassemble.

The check engine will be cleared because the battery was removed, but the real test will take 50-200 miles of driving to make sure the car's computer keeps the P0128 code off.

Some people reported the temperature dial instantly going up to "H" right away, but I didn't experience that.
