"The darker the night, the brighter the Täht."
To the world, he was the unsung hero who silently ripped the excess latency out of the Internet. To the open-source community, he was a legend known as dtaht on Reddit and @mtaht on Twitter. But behind the code was a man born Michael, who chose to live as Dave, and gave everything to connect us all.
As perhaps the final large-scale Padavan port for legacy devices, this project serves as a digital museum. Before his digital footprints fade into the void of the internet, there are forgotten stories—cold facts and warm lore—that must be preserved here.
- ⚖️ The Judge, The Hacker & The "Disappointment": Dave's father, Ron, was a respected municipal judge. Ironically, Ron once wrote that he was his own parents' "only disappointment" because he became a lawyer instead of an engineer. Decades later, Ron found himself equally baffled by his own son. Dave’s nomadic hacker lifestyle confused him. Ron would playfully grumble: "Why don't you work for IBM? You've been fixing the internet and giving the technology away for free? Again?" But Dave wasn't chasing money; he was chasing a dream. Yet, Dave inherited his father's fierce sense of justice and critical thinking—a trait summarized by a tattooed ex-convict who once recognized Dave in a bar and bought him a beer, simply saying of Judge Ron: "He was fair."
- 🎨 The Mother's Gift: Art & Music: While Dave inherited his critical thinking from his father, his boundless creativity, nomadic spirit, and deep passion for music undoubtedly came from his mother, Beverly. She was an award-winning painter, an avid world traveler, and a generous patron of the arts who even opened her home to visiting symphony musicians. Dave’s identity as a "sci-fi folk musician" carrying his guitar everywhere was a beautiful continuation of her vibrant legacy.
- ⚾ The Alternate Universe & "Extra Innings": Dave cherished a vivid childhood memory of driving home with his dad, screaming at the radio during a dramatic 19-inning Phillies baseball game. Years later, Dave discovered that specific game never actually happened that way. His beautiful conclusion: "I can only conclude that it took place in some alternate universe that only he and I shared." In 2012, as Ron was dying in a hospice, he began feverishly typing blog posts with just two fingers. Dave stepped in as his editor, realizing that for the first time since he was a boy, they were collaborating rather than arguing. "I didn't realize that he was in a hurry," Dave later reflected in a heartbreaking eulogy, mourning the stories his dad left untold. Yet, he was profoundly grateful his father's life went into "extra innings," allowing them to finally understand each other before the end.
- 🌍 The Nicaragua Origin: The fight against bufferbloat wasn't born in a corporate lab. It started when Dave was building OpenWrt mesh networks for the One Laptop per Child (OLPC) project in Nicaragua. Facing severe latency in those harsh environments, he found his lifelong mission.
- 🐈 The "International Man of Mystery": Much of the core bufferbloat mitigation was coded in open-source pioneer Eric S. Raymond’s (ESR) basement. ESR fondly recalled Dave as the "International Man of Mystery" who would crash there as a nomad, charm all the household cats, and stubbornly swear he would one day beat his friends at the hardcore board game Power Grid. ESR joked that if Dave earned a cent for every dollar of value he generated for the internet, he could have "bought the entire country of Nicaragua and had enough left over to finance a space program."
- ⚔️ The FCC Crusader & The Code You Use: When the FCC threatened to lock down router firmware in 2015, Dave rallied internet pioneers to fight back. Without his crusade, custom firmware ports like this Padavan project wouldn't even be legally possible today. As John Carmack (creator of DOOM) famously tweeted upon his passing: "There is a very good chance your packets flow through some code he wrote."
- 🕯️ Coding Through the Dark (Mike & Michael): In his final days in a hospice, Ron (born Mike) barely managed to type with two fingers, feverishly advocating for the Affordable Care Act. Though wealthy, he fought because he wanted the best healthcare for everyone. Decades later, his son Dave (born Michael) dragged a body plagued by Multiple Sclerosis and partial blindness to continuously code algorithms like CAKE, giving the best internet to everyone for free. Both men lived up to their family surname, "Täht" (which means "Star" in Estonian).
Though Täht's physical world gradually faded into darkness, our digital universe continues to shine brightly because of him.
There is a heartbreaking, yet incredibly beautiful timeline to Dave's family.
On June 9, 2012, sitting by his late father Ron's side in his final hours, Dave wrote on his blog:
"Of all these things, the one viewpoint I was sure of, the one thing I believe to be true of an afterlife, such as it is, was this: "
"That yes, we are all starstuff."
"And it made me cry to think it through."
On January 11, 2025, his mother Beverly passed away peacefully at her home, surrounded by loved ones.
Less than three months later, on April 1, 2025, Dave's own lifelong game went into its final "extra innings."
He passed away at the age of 59, joining his parents.
In life, they were Stars illuminating the world.
In death, they are Starstuff illuminating the universe.
Dave was a sci-fi folk musician who carried his guitar—famously bearing a sticker that read "This guitar kills Vogons"—everywhere. He bonded with people just as much over music as he did over code. To honor his vibrant soul, OpenWrt officially named their 25.12.0 release "Dave's Guitar."
Poetically, the legendary Taiwanese rock band Mayday (whose anniversary is March 29) has an iconic anthem called 《憨人》 (Fool). Just three days after their anniversary, on April Fools' Day, Dave passed away.
On March 29, 2020, Mayday's lead singer Ashin wrote a touching post revealing the profound mystery hidden within the Chinese title 《憨人》 (Fool). For engineers and hackers around the world, this is the most beautiful equation of humanity:
💻
憨 (Fool) = 敢 (Courage) + 心 (Heart)
Ashin wrote:
"That year, I suddenly realized that the character for'Fool' (憨) is made of 'Courage' (敢) placed over a 'Heart' (心)."
"Then, inspiration led me to write this song..."
"Let us bring this song to the courageous you, let's meet when the dawn comes."
This song is the absolute reflection of Dave's life. He refused the "sky full of gold" to give his algorithms (FQ-CoDel & CAKE) away for free. To let the global open-source community sing along with Dave's spirit, here are the full lyrics in 4 languages, completely unabridged: Traditional Chinese, Taiwanese Romanization, English, and Official Japanese.

"When you miss Dave, modprobe sch_cake!"
— A tribute to the soul of bufferbloat mitigation.
🇺🇸: His wish, I finished. Dave Täht (1965–2025) was a great open-source contributor in network technology. He turned down countless high-paying contracts just to keep his code free and open-source. Because of his research in the Bufferbloat field, countless devices today enjoy smooth networking.
🏹 A Coincidence Across Time: Archer and Arrow
There is a Chinese idiom: "A single arrow pierces the clouds, and thousands of troops come to meet."
Dave is like that cloud-piercing arrow tearing through the dark night of network congestion. Coincidentally, when he demonstrated the CAKE algorithm in 2015, the test device he used was the TP-Link Archer C7; in 2016, he used an odroid C2 to test the driver.
Today, I successfully ported his final legacy to the TP-Link Archer C2. Dave is the Archer, this code is the Arrow, and I successfully hit the target: a beautiful world without Bufferbloat.
🧩 A Belated Promise: The MT76 Prophecy
In 2016, Dave wrote on his blog that he struggled to find a MediaTek (MT76) based router, predicting it would be the rising star of open-source networking.
Years later, through this project, I've enabled thousands of MT76 devices to smoothly run the CAKE algorithm he wrote.
"Dave, I finally got this MT76 running for you!"
🌟 Light a Star, Let the Love Continue
Dave's surname "Täht" means "Star" in Estonian. If you use my firmware, please go to the GitHub open-source memorial repository and light up that "Star" for me to continue Dave Täht's spirit!

Built on the mature foundation of fq_codel, CAKE is a state-of-the-art Active Queue Management (AQM) technology. With CAKE, heavy bulk transfers no longer interrupt real-time applications. Even if your family is downloading large files, your online games will still maintain a low Ping✅.
The name originates from the movie "2010" and the game "Portal", representing the beautiful vision that everyone gets a piece of the cake. It actually stands for Common Applications Kept Enhanced. Simply put, it ensures that when multiple people use the network, everyone still gets bandwidth, keeping things smooth and stutter-free.
CAKE's primary goal is to eliminate Bufferbloat.
Its Core Features:
- Traffic Shaping: Limits ingress and egress bandwidth to ensure network packets don't pile up in nodes like modems.
- Fair Queuing: Ensures every device gets a fair share of bandwidth, preventing a single application from hogging the network.
- Automated Management: Compared to older QoS, CAKE usually only requires setting the download and upload bandwidth limits to achieve excellent results.

I believe the internet has no borders. The firmware build environment now supports 14 languages:
- English_Only (Default)
- CN - Traditional Chinese (Taiwan), simply enter
CNin the menu to get it. - Also includes: Russian (RU), Czech (CZ), German (DE), French (FR), totaling 14 languages.
It's truly a piece of cake! I have integrated all settings into GitHub Actions. You don't need to know how to code at all. Just click your mouse, and you'll get your customized firmware in minutes!
Step 1: Register/Log in to GitHub and Light a "Star" 🌟 (In Memory of Dave Täht)
Go to GitHub to register a free account and log in. Please visit the memorial repository and click the "Star ⭐" in the top right corner to pay tribute to Dave!

Step 2: Select Your Router Model and Fork the Project
Based on the code you found in the table above, enter the corresponding link and click the "Fork" button in the top right corner:
🟢 Classic Devices (Kernel 3.4) 👉 https://github.com/TW641/padavan-builder-workflow
🔵 Advanced Devices (Kernel 4.4) 👉 https://github.com/TW641/padavan-4.4
Step 3: Enable Actions
Go to your Forked project, click the "Actions" tab at the top, and click the green button "I understand my workflows, go ahead and enable them".
Step 4: Select the Correct Workflow
On the left side of the Actions page, click the corresponding workflow name based on your model:
🟢 3.4 Models: Build firmware (Ultimate Fix - Early Size Check)
🔵 4.4 Models: Custom-Router-Build-Final-Fix
Step 5: One-Click Compile & Customize (IP/Password)
Click the "Run workflow" dropdown menu on the right.
[Most Important Step] Enter your "Option Code" in the Target Model field (must perfectly match the one in the brackets from the table); for the language menu, enter English_Only (or CN if you prefer Traditional Chinese).
Customization: You can directly modify the default IP and password in the JSON field. If untouched, default values will be used. Finally, click the green "Run workflow" button!
Step 6: Download & Flash
Wait for about 10-15 minutes. Once the workflow shows a green checkmark ✅, click into the run, scroll to the bottom, and find "Artifacts" to download the ZIP file. The .bin file inside is your exclusive firmware!
