this is not subsidizing. this is way too expensive for a no-name model.

there is an algorithm called quick-select. getting median of an array should not require full sort of the whole array, only a partial sort is needed to get the median. quick-select does this.

24-bit was created because microphone want to record large dynamic range without gain switching circuit.

96kHz was created to better reproduce 20kHz high frequency, so the digital noise shaping filter does not need to be super sharp right at the Nyquist frequency.

Both were introduced for a sound technical reason. beyond that, most are marketing non-sense to cheat consumers.

Those resellers are simply just selling Kimi K2.5 or GLM5.1 as counterfeit Opus. We, Chinese, know how to play the counterfeit game for a long time in so many industry.

in a few more months, when Chinese model gets to Mythos capacity and Fable still locked down. What Anthropic will say? Why can they just admit they are not the only people who know how to train an LLM model.

At one point, I was thinking that if any of my customer send me a snail mail with an actual physical stamp on it, we will call the customer immediately and solve their problem.

There are better and superior alternative of NE5532 these days. People should just move on. OPA1612 is the king in highest-end audio performance, at least on datasheet paper.

does it really matter if LLM has conscious? if they produce working code, then it is useful, whoever if they have real conscious of fake intelligence.

we don't know what the conscious in human brain is either.

maybe it is wrong to spend 200B every year continuously to begin with.

I think what this actually means is that you can apply permanent residency in the US, but you can only get the physical green card outside of the US when the case is approved. So, the last step to get the card need to from outside the country.

This is not surprising at all. The biggest benefit of cloud model in terms of energy efficiency is that when running more than 1 requests, the power consumption of said GPU roughly stayed the same. The more concurrency requests the server can handle, the less power each request consume. The server GPU is already likely more energy efficient than local GPU, concurrency make the cost structure unbeatable by local hardware. It is generally assumed the local hardware only run 1 request, but if the local engine is meant to serve a small business with meaningful concurrency, the economy might still work out.

Every vendor defines their audio jack connector serial port differently. It is very dangerous to use 3.5mm jack. There is no pinout standard of using 3.5mm.

Even as pure audio jack, the 3.5mm connector has two standards, with the difference on ground and mic.

The type of people who need spice is dead serious about accuracy. 1ppm error sometimes is not tolerable. So, an optimization in a game engine is definitely not suitable for engineering simulation.

if the goal is to only get the median, you should not use sort. sort is O(nlogn). there are algo that give you medium at O(n), check quickselect.

B70 idles at 30W, while RTX PRO 4500 idles at 9W (measured to be 5W at wall).

B70 runs at 1/3 token output rate of RTX PRO 4500 and consume 3X idle power when do nothing.

When you get 4 of these, the idle power alone is 120W. That is a lot of electricity if left on 24/7.

At that power consumption, you also end up being more expensive than API calls and many times slower. It starts to feel very stupid to run local interference.

If the client is very keen on privacy, then they can pay for the NVIDIA.

I end up returning my B70s, and bought RTX PRO 6000.

At this speed, people end up paying more on electricity than api calls. (California electricity)
