I ran into a very weird error today. While trying to automate the deployment for this blog, I needed to replace a string in a file. The internet tutorials [1, 2, 3, 4] told me that sed would be perfect for this job and the following command should work: sed -i 's/search_string/replace_string/' filename The Error However, I kept getting tripped up by the following error: sed: 1: "i2.html": command i expects \ followed by text I spent a bunch of time trying to make sure I escaped the right char...| Kay's Blog

Earlier this year, when Spotify announced that “The Joe Rogan Experience” would stream exclusively on Spotify, it sent shockwaves throughout the podcast ecosystem. This deal – reportedly worth over $100 million – is one of the most lucrative podcast deals. The presence of this deal, let alone the magnitude, is rare for the podcast ecosystem, which is built on open principles i.e. all podcasts are available everywhere. Therefore, the concept of exclusivity does not exist in the vocabul...| Kay's Blog
January is usually a big month for tech because the Consumer Electronics Shows kicks off every year in Las Vegas. This year was no different as various manufacturers brought their latest products to showcase. Samsung and LG 2020 TVs to support AV1 decoding We have been waiting all of 2019 to see consumer devices that can decode AV1 and CES did not disappoint! Both Samsung and LG announced their upcoming 2020 TVs will be capable of full hardware decode of 8K AV1 videos from sources such as You...| Kay's Blog
Introduction It’s not often you see so many logos of tech giants on one page backing the same technology. In my experience, every enterprise has developed a case of NIH and come up with their standards. No surprise then that there’s an XKCD describing this phenomenon! But when the AV1 1.0.0 spec was finalized in 2018, with the backing of so many giants, the world knew AV1 would be a serious piece of tech.| Kay's Blog

What is LinkedIn? I have never really discovered the value of LinkedIn until about a year ago when I started using it seriously to search for a new job opportunity. I have always viewed it as a Facebook clone with a horrible and inconsistent UI. But I was surprised to discover that LinkedIn had updated their UI with a copy-paste job from Facebook. Using LinkedIn is now a much more pleasant experience!| Kay's Blog
The Tale of Two next-gen SOCs - Snapdragon 865 and MediaTek Dimensity 1000 Last month, we saw the release of SOCs expected to power next-gen flagship smartphones. Since the AV1 standard as formalized, the community has been waiting to see when SOC manufacturers add hardware support for AV1 decoding. It looks like we'll be waiting a lot longer for such a chip from Qualcomm. In what might come as a shock, MediaTek announced the first SOC to feature such support with their new Dimensity 1000 chip.| Kay's Blog
Let’s start this month’s roundup with a faster decoder! dav1d 0.5.0 & 0.5.1 release In October, dav1d saw two new releases with some fantastic speed improvements.

Often while trying to get a hold of the latest changes in libaom, you have to build the source yourself which takes time.| Kay's Blog
AVIF in Spectrum lib While browsing for AV1/AVIF updates, I noticed this commit to Facebook’s open source Spectrum library that adds support for AVIF format. https://github.com/facebookincubator/spectrum/commit/89b87bee831d3c7aabd0ad327fb118ce699df55d Spectrum is an image transcoding library for iOS and Android that is meant to be integrated into apps for image operations.

If May and June were F1 race cars in terms of speed of AV1 development, then July would probably be a Honda Civic.

In Azure, every VM has a persistent OS Disk that is used for booting the VM and contains the operating system. In addition to an OS disk, each VM also has a temporary disk that is present on the compute cluster hosting your VM. Why is my OS disk not @ /dev/sda? In most cases the OS disk is /dev/sda but in some odd cases it is not. This is not an Azure specific issue but a default Linux behavior.| Kay's Blog
It is 2019 and we need to make a decision about GIFs (no, not that one! We’re never going to be able to decide that one!). GIFs take up a massive amount of space (often multiple megabytes!) and if you’re a web developer, then that’s completely against your ethos! As a web developer, you want to minimize the bits your users need to download so that your website loads fast. That’s why you minify javascript, optimize PNGs, JPEGs and sometimes turn JPEGs to WebPs as well.| Kay's Blog

Video encoding has always been a fairly compute intensive task. With every new generation of video encoders, more computational power has been required to achieve the compression benefits. HEVC/H.265 is the latest state of the art video compression standard with x265 being the most popular open-source encoder used for encoding into the HEVC/H.265 format. In comparison to AVC/H.264 (the previous state of the art encoding format), HEVC offers about double the data compression ratio at the same ...| Kay's Blog

It is easy to use applications like Kubernetes to automate the scale out your containerized applications based on workload demand.

However, for an on-prem application going through a lift & shift to the cloud, vertical scaling of the VM is still the king.| Kay's Blog
