JRKrause commented on AI Infrastructure Landscape   ai-infra.fun/... · Posted by u/histories

Excuse my ignorance in this space but I want to check my understanding:

About a year ago I toyed with writing a web app that was essentially a front-end to a diffusion image generator (very original I know). The site used socket-io -> flask -> redis queue -> distributed pytorch processes.

Am I correct that several of these services are selling some equivalent of the '-> redis queue -> model' component? Is part of the value proposition here that you don't need to staff people with pytorch/equivalent familiarity?

Yeah we did run into a similar issue. Someone designed a power supply and it wasn't immediately obvious how the elements of the circuit were hooked up in ato.

I think a viewer would be nice ultimately. But we haven't exactly figured out how the solution might look like. ideally something that allows you to create datasheet-like snapshots of part of your design?

JRKrause · 2 years ago
A nebulous description of my ideal setup would be something like this:

Side-by-side schematic symbol view / code view that are actively synced to one-another in real-time. Schematic view allows basic arranging of parts, editing interconnects, triggering jump-to-reference within the code view, adding probe points for SPICE, displaying SPICE output graphs. Code side does all the heavy lifting like creating new parts, scripted behaviors, editing component values, all the cool shit that would be a nightmare to sort into a GUI.

Much easier said than done, of course.

Very neat, nice work.

I tooled around with a similar idea sometime back. There are clear advantages of code over graphical-schematics when it comes to automatic generation of component values / re-use of elements / speed of development / automatic SPICE testing / etc.

The primary issue I ran into was that: electronic circuits are inherently graph-structured and the traditional circuit schematic is well suited, optimal even, for displaying this kind of information. Trying to understand an analog circuit that is described as code seems awkward.

Using neural networks to solve inverse-scattering problems (like wifi scattering off a human body, for example) seems to have a lot of potential. The lack of phase-information (i.e. not just signal intensity but instantaneous phase of the EM wave) captured by traditional receivers makes this class of problems so difficult to approach since you are blind to a significant portion of the available EM information. Mitigating this by constraining your solution-space to 'reasonable' outcomes is practically very difficult... for a human. Very cool to see such a practical demonstration of a neural network seeming to accomplish exactly this.

A daily driver RX-8 that stills drives? How? What's your mileage and oil consumption like. As quirky as the RX-8 was, I liked the car but not the engine.
JRKrause · 2 years ago
Many days late on this reply but I am at 120K miles (2008 model). The engine compression is noticeably low now. Before warming up and at low RPM the car really struggles to make it up the hill out of my neighborhood. I've had 3 flooding events that were only fixed by rolling the car down that same hill 3-4 times. I have to slip the clutch a concerning amount when getting into first from a stop.

A new engine at the dealership price of $7K is still going to be cheaper than an equivalently sporty new car though!

JRKrause commented on Self-Checkout Is a Failed Experiment   theatlantic.com/technolog... · Posted by u/samizdis
JRKrause · 2 years ago
There's a noticeable difference between self-checkout stations, for example:

The stations at my local Harris teeter are unable to handle the user quickly scanning+placing products in the bagging area. I imagine this has to do with how the software translates changes in the bagging-area weight to a count of items. When this happens you have to wait around for the system to decide you aren't, in-fact, stealing.

These same stations also prevent further item scanning once an age restricted item (e.g. alcohol) is scanned, forcing you the wait around for the attendant before you can continue with your items.

Contrasted to the self-checkout stations at my local food-lion, which have none of these issues, the lack of UX is frustrating.

To top off with some non-content: You'd really think more people would have learned how to reliably scan barcodes after observing others do it hundreds, if not thousands, of times.

Wrote a letter to my local Mazda place about this. I've had nothing but good experiences with the several Mazda vehicles I've owned (still daily-drive the rotary-engine RX8...). Seeing them engage in what appears to be dmca bullying of a project like Home Assistant feels like a betrayal.
JRKrause commented on Ups says drivers to make $170k in pay and benefits following union deal   cbsnews.com/news/ups-driv... · Posted by u/shaburn

Maybe if I pay you $170k I expect you to hydrate yourself correctly via an insulated water bottle, get adequate sleep and possibly even exercise so that walking in a hot van doesn't strain you.

I sold cars after college. My company didn't buy me insoles so my feet hurt less. I didn't hound them to pad the carpet on the showroom more, or give me rubber mats to stand on outside so my feet didn't hurt. I took care of my own needs.

PS, I actually saw a car salesman pass out one day in the heat outside. He drank heavily the night before and was extremely hung over.

How is paying out-of-pocket for an insulated water-bottle / better shoe insoles any different than paying a fee for a union to collectively negotiate these things for you?

In both cases you, the worker, exchange money for improved work conditions. In the second case you are simply paying comparatively more money for larger returns.

That's what I moved to ChatGPT4 for most of my info queries. Google is badly compromised by SEO. Plus ChatGPT4 gives answer right away within having to go through multiple results and search within each page for specific line I need.
JRKrause · 3 years ago
Right there with you. I've gotten so used to having it give me exactly the answer to my specific question that, when I must fall back to traditional search, it's noticeably unpleasant.

Paper: https://iopscience.iop.org/article/10.3847/2041-8213/ace1ec/...

This is observational evidence regarding the swarm. Not anyone expressing incredulity at a collision producing ejecta.

To think the UCLA article didn't even include the photograph of the asteroid taken by DART prior to impact.
