This brings so many memories. I remember how badly I wanted an GeForce 6800 Sadly, I was never able to justify spending this much money on a GPU. Still holds true, even today.

A Roman sarcophagus was found on a beach in Bulgaria last year [1]. It was used as a bar and had holes drilled for LED lighting.

Until very recently, at the company I work for, we were running one of the largest (if not the largest) replica set cluster in terms of number of documents stored (~20B) and data size ~11TB. The database held up nicely in the past 10 years since the very first inception of the product. We had to do some optimizations over the years, but those are expected with any database. Since Mongo Atlas has a hard limit on the maximum disk size of 14TB we explored multiple migration options - sharding Mongo or moving to Postgres/TimescaleDB or another time series database. During the evaluation of alternative database we couldn't find one which supported our use case, that's highly available, could scale horizontally and that's easily maintainable (e.g. upgrades on Mongo Atlas require no manual intervention and there's no downtime even when going to the next major version). We had to work around numerous bugs that we encountered during sharding that were specific to our workloads, but the migration was seamless and required ~1h of downtime (mainly required to fine-tune database parameters). We've had very few issues with it over the years. I think Mongo is a mature technology and it makes sense depending on the type of data you're storing. I know at least few other healthcare companies that are using it for storing life-critical data even at a larger scale.

Correctly ingesting and visualizing data that's captured by different devices while also accounting for travel across timezones, is a real challenge. [1] is our guide how we do this for diabetes data generated by CGMs and insulin pumps.

Yes, zinc helped a lot in when the skin was severely inflamed and oozing. After that period passed, I discontinued it as well, because the drier the skin is, the easier it cracks.

iPhones record videos with variable frame rate, which makes them unsuitable for syncing the video with a separate recorded audio track (e.g. when recording guitars). The video and audio would ever so slightly go our of sync. I wish there was a way to use fixed frame rate when recording.

I have a severe form of allergic dermatitis that I've been trying to get under control for close to 10 years now. At one point to it so bad I couldn't take a shower without being in excruciating pain, I couldn't sleep, I could barely go through the day. The problem with all of the existing treatments, including the latest generation of monoclonal antibodies and JAK inhibitors is that they downregulate your immune system and they make you more sensitive to allergens if you discontinue the treatment. The only thing that made me better over time was stopping all drugs (including topical ones). It got worse for close to a year, but in 2-3 years my skin "healed". I'm still allergic and do get rashes occasionally, but I'm way less sensitive now.

0x70dd — Wed, 13 Oct 2021 22:45:08 +0000

Wavelets are used for pattern recognition in many iris recognition systems. First, the position of the iris in the input image is determined, then any eyelash and eyelid occlusions are removed and the iris is extracted by converting it to a polar coordinated image. The resulting image signal is convolved with wavelets of different shapes and sizes. The resulting signal is encoded using phase demodulation to produce an IrisCode. Two iris codes can be checked for a match by computing their hamming distance. [1] is the paper which describes the original system invented by Daugman. [2] is an open source implementation of that method.

I wouldn't call it healthier due to the risk of avalanches and in my experience it's not negligible. It requires some complex skills of being able to both judge the terrain and act fast if something happens. And even then, accidents happen. How many people die annually on the slopes of ski resorts and how many die in avalanches while skiing?
