Noiseless PC Audio

The first experience I had listening high fidelity music involved a Creative Sound Blaster Audigy and a 5.1 Creative speaker setup, this was back in 2003. At the time, I just plug analog outputs to the appropriate speakers, there was no noise or distortion distinguishable from the speakers. It’s a different story today, analog outputs are noisy and your speakers will bleed the electrical noise into sonic waves. A while ago I wrote about Airplay for listening but after a while I wasn’t enjoying the sync delay every time I play any video file. This also doesn’t work with Windows PC so I wanted something that works using a universal standard even though if I have to buy some more toys to do any signal conversion as long as it stays digital all the way to the DAC. ...

Microsoft Flight Simulator 2020 - What I Found So Far

Since the game launched in August 2020, this has been the game I spent time the most with over than 463 hours logged so far. Becoming a pilot was what I wanted to be before I knew how to code, learning to fly is nothing like coding, bugs are fatal. This write up sums up what I’ve found about the game so far I wish I knew before playing the game. ...

Airplay On Raspberry Pi - Hifi Setup

I’ve had this setup for a year now, it’s useful if you don’t have optical out from your devices like your laptop or your phone. Why optical out? Because analog out from computers are noisy. Noisy as in electrical noises. Without even cranking up the volume the hiss and garbled noise is unbearable. From that point on, I will only output digitally and will only output analog from either a DAC or a mixer. ...

Macbook Air M1 Experience for a Software Engineer

In short, It’s GREAT! What can I say more other than it’s just a fantastic machine to play with. At the moment I have a Macbook Pro 16" i9 top of the line, a Ryzen 5600X gaming PC and this new laptop. The i9 16" is just not in the same league as this M1 Air. But that’s not all I have to say, I’m looking at this from a software engineer’s point of view. ...

Blogging With Hugo

Before this post, my blog was a self hosted Ghost installation. I hardly update the installation, it’s been at its 0.11.x install for quite a while. It’s not quite straightforward it seems to update to the latest Ghost version. I didn’t want to use MySQL as it’s not needed for my scale, couldn’t get it to work with sqlite3 unfortunately. So I went shopping and immediately liked Hugo. Pre Migration Going to talk more about what led me to Hugo. It started with Pico but was immediately discouraged because the website is not served throught HTTPS and although I have nothing against PHP, it’s still PHP. Dug deeper about static file blogging platforms, wanted a Python alternative to find that it’s not great, it’s too bland for my taste and most importantly it looks old (sorry..). ...

Learning FastAPI By Doing - Let's Go Bro!

A few days ago I published a Python Sanic backend and an Android app of a weekend project I did a few years ago. The project was simply directing people to a random cheapest return flights from where they are, set a budget and just press Go. It was written when async Python was beginning to mature. So I thought why not learn something new (FastAPI) and compare it with Sanic. ...

Microsoft Flight Simulator - 8700K, 3700X & 5600X with an RTX 3080

As I said here and here, Microsoft Flight Simulator 2020 is beautiful. Been flying non-stop the past few months, to this day I’ve logged 229 hours of game time. Flying virtually made me remember moments and also an opportunity to learn something new. This blog post is about what you get in the game with combinations of CPU’s I’ve tested it on and RTX cards namely 2070 Super and 3080. The combinations are all feeding a 4K60 monitor with HDR turned on. ...

cTrader Bots - Runing 24/7 At Home

Lately I’ve been indulging myself in learning more about trading much more than cryptocurrency. During the last 2 weeks I jumped head first into Forex and Precious Metals. It’s different, volume is always high, unlike Bitcoin. Gained a new perspective, while other people might see as manipulation, I see how market maker moves as just another day at the office. Anyways, I learned how to automate some parts of the tradings, here’s what I experienced. ...

The Case Of Pairing 3700X and 3080

It has been known that the 3080 is a power hungry GPU while 3700X is supposedly a power efficient CPU with a TDP of 65W. Pairing the two should not be a problem powered by a Corsair RM 750W PSU, or is it? Here’s what happened to my rig. Hardware Spec Before anything else, here is the spec I built: AMD Ryzen 7 3700X Corsair H115i Pro AIO Watercooler AsRock X570 Taichi Motherboard 32GB HyperX Fury 3200MHz Palit Geforce RTX 3080 GamingPro OC Corsair RM750 80+ Gold The Problem The same 3080 was paired before with an Intel i7 8700K rig. I had no problem whatsoever from the hardware. Ran everything just as it should. But there were the occasional stutter when playing Microsoft Flight Simulator 2020, my theory was that there wasn’t enough bandwidth somewhere to do something. So I tried to pair the 3080 with my AMD rig. ...

Microsoft Flight Simulator 2020 - Beta Testing Using Your Customers

First of all, WHAT A FLIGHT SIM! In terms of graphics, I don’t think there’s anything close to rival. Leveraging Azure’s worldwide CDN to stream content is a brilliant feat, flight sim content being dynamic means improvements to the content will be delivered faster to us. Picture perfect graphics though comes with a hefty tax on our PC builds, this is next gen material. Built for MSFS 2020 As much as I love the graphics, was not impressed with frame rates. I bought a new casing to house a PC built for this game. Expected to get decent 50-60 FPS but I wasn’t getting it. ...
