Resolving blank screen issue while watching Netflix with DisplayLink Docking Station

This issue specifically affects users who utilize a DisplayLink docking station. If you’re a Mac Mini M1/M2 user like me, with multiple monitors connected through DisplayLink, you may have encountered a frustrating problem while streaming content from platforms like Netflix, Amazon Prime, and Hulu. This issue manifests as a lack of display, despite the presence of sound. Initially, I noticed it only occurred in the Chrome browser, while Firefox and Safari continued to function normally. However, over time, the problem seemed to affect all browsers. Even after attempting common troubleshooting steps, such as clearing cookies and updating DisplayLink drivers, the issue persisted.

To be fair I think it might happen to Windows user too. But I didn’t cross check. Suprisingly Youtube is not impacted.

How to bypass the Apple Mac M1 external monitor display limitation

Multiple monitors on M1 Chip — Three Full HD monitor + WQHD Monitor (in the middle).

M1 chip really surprised us when it was launched back in 2020. The chip performs really well with good power efficiency. There are some cons to this powerful chip. You can only output one external display from a Macbook Air, Macbook Pro, and Mac Mini M1. This is not the case when Apple still uses Intel chips. Intel HD graphic was able to drive at least two external displays just fine.

How to recover deleted ABAP Program

Have you accidentally deleted an ABAP report program and you would like to get it back to refer to that certain piece of code?

I just learned this trick. Go to SE38 and create a new program with the exact name of the ones that are deleted. This is an important step. Once done, view the new program. It will be empty of course. Click version management.

From here you will be able to view your existing history of the code. Select which version you would like to revert to.

This is how you restore/recover deleted ABAP Programs.

How to show the line numbers on Python IDLE

If you are using Python version 3.7 and below. Tough luck, you can’t show the line numbers on the left sidebar. You can only rely on the line numbers on the status bar at the bottom of the editor. Which is not helpful for some people.

For people like me, who already familiar with the line numbers with other IDE’s, this simple small feature is a must. You need to upgrade your Python to the latest version, as of now is version 3.8.

The new IDLE comes with python 3.8 has this new feature that can show line numbers on the left side of the editor.

Is anyone still using IDLE? For me, yes IDLE comes in handy when I’d like to test some small script quickly. When in full development I’ll be using VS Code.

Steps to enable the line numbers.

Go to the Options tab, click configure IDLE and click General tab.

Lenovo ThinkPad X240 Hackintosh Success Installation

I’ve managed to install a Hackintosh on Thinkpad X240. Thanks to broad hackies community internet to make this a success.

I’ll try to compile the all the steps that I gather from the net into one central place here. For anyone who owned a Thinkpad X240 or similar Thinkpad family that would like to try install Mac OSX.

My Github pages that contains all necessary kexts required for the installations.

https://github.com/izzatz/Lenovo-Thinkpad-X240-Hackintosh

I’ve followed a step by step guides from Tonymac forum.

So far everything has been working fine. Except couple of setbacks due to hardware limitations.

a) No built in wifi support. As Thinkpad use a different chip that being officially supported by Apple. Solved this by getting a small usb wifi dongle from TP Link TL-WN725N. Works like a charm Plug and play.

b) Bluetooth connectivity. This issue is bundled together with wifi issue since it is a same card. You can fix both of this issue by replacing the card with a friendly hackintosh model. But you need to do the bypass and whitelist BIOS stuff. Which is too cumbersome. Solved it by buy a small bluetooth dongle. Easy and clean solution.

c) Audio issue. Supposedly base on the guide it shouldn’t be a problem to get a working audio in Thinkpad X240. But I don’t know why, maybe I messed up my kext. It didn’t work for me. My solution is by getting a usb sound card from Ugreen. Issue solved! It can support my 5.1 channel speaker too. Good stuff.

WORK IN PROGRESS. WILL UPDATE FROM TIME TO TIME.

Upgrade Lenovo X240 display to IPS Full HD

DIY upgrade on a personal laptop.

Lenovo X240 is a great laptop. Minus the bad display and the badly design touchpad. X230 and X250 touchpad is much better. The button was on a separate panel. Other than that, all is good for this 12 inch small companion of mine.

This is my secondary machine and this laptop always connected to my full hd external monitor. Because I can’t stand working on the horrendous display. Default display panel is a TN display with 1368×768 resolution, bad viewing angle and definitely a small resolution for a programmer. It may be cheap solution for the manufacturer but very bad experience for the consumer I must say.

If you were planning to buy a new laptop, please buy at least a full hd display. Great for your eyes and big screen estate. Much stuff you can fit on your display at a time. You won’t regret it. 1368×768 should be ban on a new laptop!

Lets get started!

Launch task bar pinned app with Windows Key + Number keys

I just found out this cool tip from, https://www.reddit.com/r/pcmasterrace/

Say you have a bunch of pinned taskbar app, little did I know you can launch it using your windows key + 1, 2, 3 (any numbers based on your app placing sequence). It doesn’t work with numpad though.

So let’s get started. Reorganized and prioritized the app on your pinned list. Save that few milliseconds to procrastinate.
