Sounds great! I think I’ve actually stumbled across info-Beamer before. We use pretty much the exact same approach in re: configurable zip deployment for BrightSigns. It would be great to chat some time! I’ll shoot you an email.

If you have fixed media (as opposed to realtime dynamically generated or streamed etc) this trick can go a very long way - or even if it is generative, if the time is used to drive the animation. It just requires good clock sync, like you s

The deprecation of OMXPlayer has been problematic for one, since I rely on some custom applications which need to be able to have some fairly precise/low latency requirements between when you tell it to start playing vs when the playba

I entirely work with museums, where there are lots and lots of considerations in re: rendering device. The considerations for eg a commercial display are a little different, but I don’t have experience with working with those sorts of clien

Reliability is a big part of it - but they are not really all that expensive for what you get IMO, especially in an enterprise context. A BrightSign is effectively a very sandboxed Linux box (you can SSH into them!) which has extremely reli

Congrats on delivering this fun project! I do a lot of work with synchronizing media content across devices so it’s always fun to see the solutions people come up with. You probably came across them in your research, but the industry standa

Yeah, that makes sense. We are lucky in that we get to deploy our code to the devices. It’s not really “embedded” in the sense most people use as these are essentially sandboxed Linux devices that only run applications written in a programm

I run a small SaaS side hustle where the core value proposition of the product - at least what got us our first customers, even if they did not realize what was happening under the hood - is, essentially, an implementation of NTP running ov

Supabase consistently puts out such fantastic bite-sized gems - and for me some of my favorites have been related to PostGIS - whether it’s about serving tiles directly, or this (ab)use of functionality typically used in a PG geospatial con

Even if projects use BIM internally it’s still completely possible that the final deliverables are all PDFs/drawings/etc generated from BIM/internal models for contractual/liability reasons etc.

It seems like, with sufficient users entering data (including previous sales/purchases if desired), you could begin to train models to take into account local/regional factors etc. do you have any long term plans to collect user d

by szvsw 2y ago
How do you define adaptation and learning? What about say, an autoscaler which is programmed to just track the the load for every hour over the last week, and use the average of the last 7 days at 8am to pre-emptively auto-scale? Is that le

Any matrix multiplication can be trivially unwrapped into a bunch of for loops with basic arithmetic. In fact, that is exactly what any GPU kernel ultimately does in some sense. What differentiates a “traditional computer program” from a si

Yeah, wouldn’t P(success) = 0.2 be pretty fantastic for any highly experimental/speculative/moonshot research entity?

You have to worry about changing the ground temperature even on earth FYI. When designing district heating/cooling systems with borehole fields, one of the things that you check for is to make sure that you don’t inject too much heat (

Yes, I think along similar lines there… but on the other hand, brands need not reflect underlying truths about reality, and in fact often do not. Suppose two years from now, it is revealed by a whistleblower that they were part of a special

One of the most brilliant pieces of production design (in my opinion) is the choice to make paper octagonal via trimmed corners in the BSG universe. Such a wonderful way of communicating that the world is other, or ours but through some str

In the modular synth/music world, this is sometimes referred to as GAS… gear acquisition syndrome. As always, it’s not the tool, it’s how you use it… and as always, being creative is always hard, and the challenge is (usually) within y

Not quite, though very related and I believe both should end up with essentially the same result. Matching pursuit is essentially a greedy algorithm, if I recall correctly - please do correct me if I am wrong, where you conceptually find th

The first time I used L1 regularization to recover a sparsely sampled signal’s DCT coefficients my mind was blown. If you’ve never tried it out, you should, it’s pretty crazy! The power of priors and choosing the appropriate inductive bias…
