In Part 3 of our series, we explored the hardware device elements of the Reolink RLC-810A ― focusing on the NAND memory. We continue with Part 4 of our exploration into an IP camera firmware through introducing the concept of a file system. Furthermore, we will explore the technical reasons for choosing the UBI File System (UBIFS), a file system used especially for a category of mass storage, and we will unpack the UBIFS part using the ub..

I love this blog post. Thank you for writing it. I must add one thing: every accessibility audit needs to test with forced colors. Countless sites claim to be accessible but fail this basic check. For those less familiar: forced colors is a standard feature defined in the CSS Color Adjustment Module Level 1 . It overrides colors with a user-preferred palette. Implementations include Windows High Contrast Mode and Firefox on all support....

Synapse is incredibly slow, which is why I run the Conduit matrix server . Server performance is the main price paid for Matrix’ history replication. This also gives Matrix a spam DDoS problem: sometimes people mass-create accounts on hundreds of servers with open registration, and mass-join rooms. The flood of thousands of join-events will OOM most connected servers. My Conduit server (RocksDB backend, 1 vCPU, 1GB RAM) is actually fast ....

Slack’s business logic for showing notification periodically appears in LinkedIn posts and such. In Slack’s original post, this diagram was meant to illustrate what logic was being transferred from the multiple Slack clients to the server, but the diagram has since been taken as an example of product complexity and how development is harder than it may sound . In contrast, I think the diagram obscures the intended logic, but the logic i....

Warning: This Article Is Poorly Written With the ongoing collapse of Twitter, there has been a lot of talk about the Fediverse, and primarily Mastodon, which in spite of it probably not wanting to be, is the flagship in the ActivityPub fleet. I want to preface this by saying that I think Mastodon is really great software from the user side. It’s a very powerful tool and deserves all the credit it gets for it’s UI, it’s filtering features..

When we discuss resistant statistics, we typically assume resistance to extreme values. However, extreme values are not the only problem source that can violate usual assumptions about expected metric distribution. The low-density regions which often arise in multimodal distributions can also corrupt the results of the statistical analysis. In this post, I discuss this problem and introduce a measure of resistance to low-density regions.

It took me several seconds to parse the casual quip “But, aren’t you folks web2?” . I probed further and they continued— “Isn’t Zerodha [1] web2? Why don’t you convert it to web3?” . For the next few minutes, I struggled to explain how technologies, processes, people, regulations, laws, industry, and the entire legal and societal foundation that underlie an organisation, no matter how imperfect, aren’t “web2”, and that they can’t just b....

Arrived an hour before sunset, so only hiked just over a couple of miles out and back again. Although short, it was well worth the trip. The skies were clear, and Garfield Mountain descended into a deep shade of red as the sun went down. Along the first mile there are several expansive views looking north-east. After a mile or so, we spotted a Gold Crested Kinglet, with a vibrant yellow stripe on its head. We could also hear other birds i..

Mach engine uses Zig as the C/C++ compiler for almost everything. Unlike other toolchains, Zig enables many more safety checks by default - such as clang’s undefined behavior sanitizer. Using Zig, we’ve caught undefined behavior in established projects like GLFW[ 1 ], the DirectX Shader Compiler[ 2 ], and more. Undefined behavior is everywhere, often relatively innocuous, and hard to catch. Professional C/C++ developers know to run U....

Re-published from a 2019 Medium post If you were asked to envision an archaeologist, what would come to mind? Perhaps an Indiana Jones-esque figure, digging in dusty soil in search of a long lost treasure. Petra This is the romantic idea of archaeology fed by the media. However, today’s biggest challenge in archaeology is not to make new discoveries, but to work through the ever-increasing body of already excavated and d..

When Oppenheimer quoted the Bhagavad Gita, he had realized the impact of the greatest inventions in the history of the human race, one of his own creation: the atomic bomb. This advancement had come out of necessity to outpace wartime....

Re-published from a 2019 Medium post : Would you guarantee the happiness of a whole city in exchange for the misery of one poor soul? In Ursula K. Le Guin’s short story “The Ones Who Walk Away From Omelas,” we reach this moral dilemma: is the intense suffering of one boy worth the happiness of a city? I would like to encourage any reader of this article to read Le Guin’s story first — it’s a relatively short read, and in my opinion, ..

As some of you are probably aware, I have the habit of going on two cyclical “kicks”, every year. Right now I’m going through a health-kick, which means I’m going to try a bunch of self-improvement type things until I forget I was doing them. Anyways, I’ve been seeing Headspace ads everywhere lately, so as a form of core rejection of their business model, I’ve been meditating on my own.
