I think the text is wrong, it's diffing two frames and the areas that are the same are where the scorebaord is as this doesn't change between frames but everything else does.

Of course it's not worse, these numbers have huge error bars. Statistically the two statistics are not significantly different. But trying to explain that to most people with no knowledge of statistics is tough.

$313 thousand not million which seems reasonable enough.

I guess the probability of impact won't reach the >50% level until a few months before impact due to variations in earth's orbit and by that point the ability to do anything about it is limited.

There's far too many variables in skin for any non invasive techniques to work reliably in measuring blood glucose levels. The patches work fine and are highly accurate. The real next innovation is implanting devices inside the skin bu

Neither of those languages gives you portable SIMD. Rust is rapidly becoming the language of choice for high performance code.

You need to be far more specific than x86, x86 is just the instruction set, the actual architecture can vary massively with the same instruction set. In general though there is no penalty for interleaved operations.

These days CPUs are so complex and have so many interdependencies that the best way to simulate them is simply to run them! In most real code the high throughput of these sorts of operations means that something else is the limiting factor.

If you take these corporations to court these arguments don't stand up. In your oil example, if you had a warranty claim due to say a broken suspension component then the type of engine oil used wouldn't be relevant. It just allow

But these solutions require two chips, one for bluetooth and one for wifi where the ESP32 does it all in one.

An interesting use for satellite in future will be accurate estimation of solar power output in the very near future e.g. in the next hour period such that grid operators can adjust storage and demand to get a balanced grid. At the moment w

It would have been a better demo if reduced to more manageable numbers e.g. a deck of 2 black and 2 red cards. Turn 1 r = b so no bet Turn 2 bet 1/3 on whichever card wasn't revealed in turn 1. Turn 3 either you were wrong on turn

Stack too small - there's no proof the 8k allocated is too small, is it really exploitable? Non async functions - pretty common problem but difficult to actually exploit. Every developer who has worked with signal handlers has probably

2^(12*4) is 281,474,976,710,656 possible 12 character strings so seriously impressive that it can look through that many in an hour.

Which is why the UK is putting in subsea cables between Scotland and England despite the added cost.

With this sort of tech it only achieves good usability if it is accurate a high percentage of the time. Anything less than 90% accuracy on a whole trip and I likely won't trust it. So that means getting to >99% accurate on each unde

The main problem is various vents along the side of the hull. Typically these are placed closer to the centreline of the vessel such that they can't be flooded at extreme heel angles. On luxury vessels they are placed out of sight of g

Does anyone know why Mistral use a 17 bit (131k) vocabulary? I'm sure it's more efficient at encoding text but each token doesn't fit into a 16 bit register which must make it more inefficient computationally?

This is why I don't like semantic versioning. Semantic versioning only covers the "public API" but even the smallest "patch" change can result in a change in behaviour which has a big impact on the users.

Could I ask you to clarify why avoiding safemode is so important? In a non satellite system safemode means everything is driven to a safe state which is fine during testing in the lab. Also do you not run these tests in an even more simulat

Battery life is based on playing a 720p video file so most of the expended power will be in the video decoder and screen not the actual CPU. It's also dependent on the battery size in the laptop being tested so pretty much impossible t

No studies at all, all the claims are anecdotal at best.

If you look at the actual study the effect size is very slight https://www.researchgate.net/profile/Isabel-Gauthier/publica... The correlation may be just above what the author thinks is significant but eyeballing

Pulse width modulation works just as well if the pulse width is short compared to the overall cooking time. And not having an inverter makes it more efficient. Unfortunately lots of cheap microwaves have a pulse width which is more than 10

Great toy but it's a bit misleading not to touch on the query planner. All real SQL implementations will plan how to most efficiently run a query so the order of operations can be wildly different to expected based on the data and inde

Yeah a PLL without a status flag to indicate it is locked isn't good. I think there are also issues with stabilisation when using it with stop modes https://community.st.com/t5/stm32-mcus-products/msi-pll-mode

According to the documentation there is no calibration as such, the MSI clock simply runs in a phase locked loop (PLL) configuration with LSE (32.768 kHz). For example in 1MHz mode the MSI is setup to run at approximately 1Mhz, this clock t

Formula seems to be round(num_social_media_posts * 460.85) Where 460.85 comes from is unsure, but I guess a calibration factor based on some more reputable data set.
