My last post about my hackintosh is when I was still on Ryzen 3700X/X570 pair. It was overkill for my day to day work, instead I built a new PC just for the hackintosh and used the higher end pair for gaming. It was a great decision, introduced me to the microATX form factor. For a work computer (trading and programming), a microATX board fits my use case. It’s small but it’s big enough to host all my peripherals. I started with this spec. ...

For the longest time, I’ve been wanting to write a trading bot to leverage on TradingView’s alert system. For any indicator or strategy you use, you can set up alerts which will then send the notification to various destinations including a webhook. They have a strict 3 second must reply rule which is not trivial the first time I thought about it. Persistence and a lot of codes later wins though, found a way. ...

This is the second round of Bill Williams for me. This time it sticks and I built a system out of it. This is after paying a hefty tuition fee (losses), no more. As do with anything in life, the usual solution for complex problems is likely simple albeit far from easy. How It Usually Starts As I said here, the most difficult concept for me to comprehend initially is Support & Resistance. This is likely the first thing anyone learned. I understood it eventually by understanding Fractals. ...

Anyone who trades using Technical Analysis knows what indicators are for sure. There are plenty of them available. As trading is becoming more serious instead of a hobby for me, I have an itch I need to scratch. I want to easily determine when to long or short given a set of indicators using predetermined (naive) assumptions of values. Indicators Here’s a set of indicators I use for a strategy. I started with these indicators to write my Bayes Oscillator. ...

In most second semesters of Computer Science courses in Indonesia, students will learn about a course called Data Structure. In my case, it was a course about LinkedList taught in the C language. Of all the courses I took, this was the only one worth remembering all this time. Having an ever-connected list in which every node points to its previous and next nodes. The first being the head while the last is its tail. It’s time for a new head. ...

I have never in my life built an AMD CPU based box, never. BUT, AMD’s rise is well on its way to dethrone Intel off of the performance perch. Over the years, I usually upgrade my machine every 3 years whether it’s a laptop or a desktop. I’ve had my Intel i7 8700K for 2 years now, I’ve made a lot of work with it, it’s great. The blow for me with an Intel box was that Intel decided to abandon the LGA1151 socket for its newest CPU’s. Not to mention Intel’s BIOS limit preventing 6th-7th gen CPU’s not being able to run on 8th-9th gen chipsets vice versa. While AMD was improving and iterating at a phenomenal pace. Other than its impressive 7nm process which is a leap ahead of Intel, Ryzen have more cores/threads than Intel, period. ...

After installing Roon for the first time I’ve been using it everyday. How I use Roon has changed along the way. A mixer was directly plugged into my Hackintosh but now it’s plugged to a Raspberry Pi. I can now listen to music even though my Hackintosh is not powered. Discover This feature alone I think is worth half of the subscription price. Roon with its awesome metadata power will recommend you songs, albums, artists and my favorite is artists you don’t even know you had in your library. ...

I love Roon! After trying it out for 14 days, I bought the subscription. It’s just so easy to manage my FLAC library with Roon. The number one feature I love is Roon’s attention to high quality output and flexibility to play music to any receiver. My receiver is a Raspberry Pi. A few days ago I set up my Raspberry Pi to act as a Roon Bridge. I plugged my USB mixer to my Raspberry Pi allowing me to listen to music even if my Hackintosh is turned off. It’s a simple Behringer Xenyx Q502USB. Before using this mixer, I plugged a Behringer UMC202HD but was disappointed by the loudness, but then it’s powered from the USB bus so fair play to it. Plugging to the small mixer made a world of difference in loudness. ...

The title is not clickbait, it is what it is. For my Unraid box, I used 3 SSD’s I bought from Vgen. The first SSD was bought a year ago, it was a data drive for my work computer. The other 2 SSD’s was bought a few months ago. As it turns out, not all SSD are made equal, even if they were from the same brand. The packaging says it’s 550 MB/s reads and 477 MB/s writes. Here’s a bit more detail about the drives I bought from fdisk. ...

Just can’t saya this enough; UNRAID IS GREAT! Ever since I assembled my Unraid box and got it licensed, I have now used up more than 50% of my storage space. It’s time to upgrade to prepare adding more storage when it gets to 80%. With this rate though, I think I’m gonna have to seriously consider moving from SSD to mechanical drives. The final spec for the upgrade is below: ...
