I have been having issues with my Intel Core i7 MacBook Pro - as the notebook heats up, the LCD display starts to die. Initially the display would glitch - black bars or lines of dead pixels would appear at the bottom of the display,. Then these dead portions start to “jump” causing the display to flicker. The glitches progressively affect a larger and larger portion of display, until the display gives up and just just goes blank! Perhaps the flexgate design flaw with the ribbon cable between the motherboard and display...
When I first used Grav, “a modern open source flat-file CMS,” to host this site, I setup a local development environment using macOS’s built-in Apache and PHP. But this is getting harder with each macOS release, so it’s time to use a Docker container instead.
In the Windows 10 Start Menu, I used Pin To Start to a medium sized tile for Firefox - and the icon is nice and large - but is not the case for other shortcuts. I was wondered why... and how to make all the icons have a more consistent look.
There are multiple ways to run Linux GUI applications in a Docker container, but today I’ll highlight a method that I found interesting: using Xpra to forward X11 screens from containers to a web browser. This post is based on Eugene Yaremenko’s docker-x11-bridge, which I simplified.
I’ve been putting of this post for too long. I use Bulma as the CSS framework for this site. I previously used Bulma Customizer to customize some settings but this does not seem to work anymore. So here is how to customize Bulma CSS yourself.
I wanted to re-purpose an old Linksys WRT54GL by overwriting its firmware with the open source DD-WRT firmware, because the original Linksys firmware does not support a wireless repeater setup. A Wireless Repeater is used to “extend” the range of a primary wireless router by connecting a secondary wireless router (i.e. bridging), and routing Internet-bound traffic via the primary router. Here is how I got it working.
I recently posted about configuring RTSS to overlay CPU and GPU information on games in Windows 10. Here is my setup for Cyberpunk 2077, so that I can keep an eye on my framerates (when testing the plethora of graphics settings), CPU / GPU / RAM utilization and temperatures.
I though I’d quickly post my Cyberpunk 20774 settings running on a Nvidia RTX 2060 at 1080p (920×1080). The default Cyberpunk Ray Tracing Medium preset results in low frame rates and rather blur graphics, although all effects are enabled.

I bought a cheap-ish mechanical keyboard from 1stPlayer, the DK 5.0 Lite 87 along with the DK 3.0 mouse. I called this purchase “a mistake” as I am not quite satisfied with the physical build and the very poorly designed software. So, I figured I might as well do a short review that may help prospective buyers.
I suddenly experienced a strange issue today - the row of number keys on my 1stPlayer DK 5.0 Lite mechanical keyboard, i.e. the keys from
9, would output the wrong number! Specifically, hitting all numeric keys in order would output
1678923450 instead of
1234567890. This happened while gaming and I have no idea what caused it.
Just a bunch of un-related findings that may help when creating Windows and macOS VMs using VirtualBox.
On my new Windows 10 desktop I wanted an on-screen display (OSD) of system performance overlay while gaming - similar those benchmarking videos one finds on YouTube. While I don’t overclock my CPU or GPU, I still do want to know the utilization and temperatures, as these give me a hint as to whether the system is thermal throttled or bottlenecked.
I found that Oracle VM VirtualBox 6.1 was running very slowly on my brand new Windows 10 PC.
Initially I thought it was to do with VirtualBox, e.g. insufficient cores or memory, the display controller (VBoxSVGA), insufficient video memory, etc. And then I thought it might be an AMD thing, so had a look at BIOS, e.g. nested AMD-V, etc.
We will remember 2020 for all the wrong reasons, but on a lighter note, 2020 has been quite the year… for silicon!
- The incredible performance of Apple’s M1 and A14 (@ 5m).
- AMD crushing Intel with its Ryzen 5000 series CPUs (@ 7nm).
- The neck-and-neck race between the AMD Radeon (@ 7nm) and Nvidia RTX.
- The launch of next-gen consoles from Microsoft and Sony.
I just got myself a new desktop PC! I am not much of a Windows user, but am looking forward to Cyberpunk 2077! I have never built a PC before, so I did the research and learnt a lot. Here is what I bought and why.
Here is a quick iOS Shortcut to join Cisco WebEx personal rooms by email name. In my organization, once logged in to Cisco WebEx, we can join a colleague’s personal meeting room just by his or her email name. Here is a shortcut to either:
- Launch WebEx for the contact from the Contacts App share sheet,
- Or just run the shortcut to select email to launch WebEx.
I use macOS spaces (virtual desktops) to arrange the various apps I frequently use. I have one space setup with two Firefox windows, in fullscreen Split View mode. But by default, Firefox windows are not really “full screen” for me, in that the tabs, toolbar and bookmarks bar will still be displayed. Here is my workaround to force the browser to full screen.
I’m always eager to learn about the open source tools or frameworks developers use. I found this list a good “read” :P
