Disable Hiberboot
More than one Acer Aspire laptop has had problems with screen blacking out or flickering
after boot. To resolve this issue, you can disable Windows 10 Hybrid Boot or
Fast boot function. By doing so, you may also increase the life of a solid state
or M.2 drive, because the O/S RAM will not be dumped to the drive every time you shut
the computer down.
- Open registry editor (regedit)
- Navigate to HKEY_LOCAL_MACHINE / SYSTEM / CurrentControlSet / Control / Session Manager / Power
- Double click HiberbootEnabled and assign the value 0 to it
Alternatively, copy the following text to a file with a .reg extension:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerPower]
"HiberbootEnabled"=dword:00000000

Copy the node_modules/chai folder to your public (or public/lib) folder
Include mocha in the page you want to debug
<html>
<head>
<link rel="stylesheet" href="lib/mocha/mocha.css">
</head>

<script>mocha.setup('bdd')</script>
<div id="mocha">
</div>
<script>
mocha.run();
</script>

{
"version": "0.2.0",
"configurations": [
{
"name": "chrome debug",

Static USB device name
When a device name is important (e.g. a line printer device such as /dev/usb/lp1), the
name could cause problems when multiple devices could change the device name sequence
at boot time or when devices are plugged or unplugged. The UDEV subsystem provides
a way to statically name these devices or symlinks to it.
It is recommended to specify static symlinks rather than device names in order to
avoid blocking adding devices if names already exists.
In modern versions of Linux, udev rules replaces the need for usb_modeswitch. In stead
if editing files in /etc/usb_modeswitch.d, you have to add configurations in
/etc/udev/rules.d.
- Find the USB vendor and product IDs
lsusb
# or if you cannot recognise the USB device, but you know the current device name
udevadm info -a -p $(udevadm info -q path -n /dev/usb/lpX) | grep -B 3 -A 3 idVendor
# Replace /dev/usb/lpX with the actual device number
Add a UDEV device ADD rule by editing /etc/udev/rules.d/10-local.rules and adding the following:
ACTION=="add", ATTRS{idVendor}=="1504", ATTRS{idProduct}=="003d", SYMLINK+="pos"
# Change vendor, product and name of symlink
# In this example, plugging in a POS printer creates a device symlink /dev/pos
Refresh UDEV rules without rebooting
udevadm control --reload-rules
udevadm trigger
Unplug the device, wait a few seconds and plug it in again
Verify that symlink exists
Change application configuration
# For example, change CUPS printer
service cups stop
# Edit /etc/cups/printers.conf and change the line printer device URL to your symlink:
# e.g. DeviceURI parallel:/dev/pos
service cups start
