Are any facts knowable? Besides the fact that something exists, in some shape or form, at this particular moment, that allows the thought about this to happen.

?? Some people do agree that the Electoral College system was more suited for a previous time where the States were more disjointed and the federal government wanted to entice each state to participate in the system by giving the smaller states more power. In modern day, a system that's closer to people's actual votes makes more sense to some people. This simply allows changing from Electoral College where a candidate can win despite having less votes than another candidate, to a more true first-past-the-post.

Of course, I think ranked choice voting is much much better but I don't think it's fair to make this sound like some secret nefarious conspiracy. It's also not apparently related to the article

Agreed. Super pedantic comment: it's Battle off Samar.

Ah I see! I was a wee baby back then haha

It's not as big of an issue for us since we use nearly all consumer/industrial stuff with build in ESD protection. I was also using it as a way to stress test whether the board would develop problems from handling, temperature and humidity changes, shock and vibration, etc

Reporter. I saw a pretty cool visualization of someone's activities over a year, and decided to give it a shot. I gave up after the first day because of how annoying it is.

Cubesat Developer's Workshop? Which year was this, if you don't mind me asking?

The funny thing is that I did pretty much the same thing, I had our flight computer prototype in my hoodie pocket to fidget with (since I'm leading all the electronics for the project) but luckily we weren't travelling far and didn't get any invitations from the government folks.

As someone with mild knowledge of semiconductor fabrication and optics, I honestly think these technology are not that meaningful to justify their cost of development and implementation, compared to the winning solution of arbitrarily complex plastic lens assemblies.

Chromatic aberration can be good enough with doublet lens design and Petzval is largely solved by the final field flattener usually with multiple concave and convex sections, and you can still easily fit a large number of lenses in a small formfactor.

Additionally being able to adjust the power of a lens is not a huge gamechanger, as a lot of the complexity with modern optic design is to counter various defects and distortion like aforementioned Petzval.

Rather, the fundamental limit is the sensor size. It's just not practical to achieve much better image quality with a physically small system

This is AI generated which makes it more uncanny than it needs to be. But honestly, what's wrong with wanting to document something by taking picture or video? It's a natural thing that humans want to do, whether by writing it down or sketching picture. Digital photography and videography has now just become much more accessible due to lower cost and near ubiquity of high resolution imaging devices.

Didn't we get to brag about it already? The value of continuing to have the capability seems to be outweighed by the costs of maintaining the facilities and equipment

Is there much practical reason that requires sending people to the moon still? Modern robots are cheaper and can perform science more effectively than any human

Have you tried 10 kΩ for LED and FET pull down?

100 Ω sounds like way too much current for modern LEDs. I often end up using 100 kΩ especially for green LEDs. They are very visible under indoor lighting even with 1 MΩ and 3.3 V supply.

For pulling down FETs, you want something in the range of 10 kΩ. 10 MΩ sounds way too high, which makes your circuit sensitive to being touched or affected by moisture, especially if there are near by components connected to the power rail.

My digital electronics grab bag consist of 22 mΩ for sensing, 100 kΩ for battery voltage divider, 22 kΩ for one of the 3.3 V buck converter feedback dividers, 10 kΩ for everything else like I2C pulling.

High precision resistors are often necessary for metrology applications like very precise and low drift voltage sources. Often parts like Vishay's same-substrate thin film resistor networks [0] are used, as the temperature of each resistor leg are kept the closely relative to each other, resulting in the ratio between them being stable against temperature changes. Even if you use some adjustable/tunable circuit, you usually still require some sort of precision resistor network as an original standard.

In general, however, it's much better to measure/sense physical phenomenon by first converting it into frequency, because it is much easier to measure frequency precisely. Using something like a TCXO from Seiko Epson with 1 ppm tolerance, and measuring over time, you can easily achieve 0.00001% precision and beyond. I know that strain gauges used in civil engineering often utilize this concept, where a metal string is "plucked" electronically and the frequency is then measured.

A lot of steps are being taken to "stay ahead" though. Consider something like the CHIPS act, I actually got offered a research grant for the summer from it. This is the first time I felt such direct influence and urgency from the politicians

The input to the algorithm is literally three numbers: total words, total sentences, total syllables. If this counts as AI, then your thermostat or film camera feels pretty AI too.

Looks like the author draws a lot from Edward Tufte's The Visual Display of Quantitative Information - I would recommend it to anyone interested in design, it's a very interesting read with a lot of neat visuals. Some complain that it might be a bit heavy on map related examples, but I say that's no problem since maps have pretty much the same goals as effective UX, that being organizing and presenting information to the user accessibly.

I'm not sure what you mean. The biggest FPGAs do not have hard processors built in. Those which do feature hard cores usually advertise it specifically.

See Xilinx's UltraScale+ Kintex and Virtex series, both able to have more logic elements than the Zynq MP equivalents https://docs.amd.com/v/u/en-US/ds890-ultrascale-overview

Have you used polycaprolactone/PCL aka "InstaMorph" for hobby/projects? It's a very tough plastic that can be melted by putting it in hot water, then formed by hand. I think something like a linkage made out of this material could be a fantastic intentional failure point for certain mechanical systems, as long as the temperature requirement is not much higher than human conditions. Also, if you have a hot air blower, you can repair it in-situ.

I'm honestly not sure why we don't see more of this plastic used for consumer stuff. Something that you can melt down and fix stuff or make little ornaments sounds like a great marketing gimmick. It's also generally a pretty bio-safe plastic.

But often, temporary bridges that can be moved and assembled and hold traffic are straight.

It's so funny that Forbes seem to mistaken Portland Oregon for Portland Maine? They quote their own article that says "Maine Winner Nabs $1.35 Billion Mega Millions Jackpot.."

I was doubting myself but the apnews article shows a video with Oregon Lottery and mentions of Salem and Oregon laws... I'm pretty sure this isn't in Maine haha

Communication protocols that incorporate spread spectrum (code/direct sequence for GPS and chirp spread spectrum for LoRa) get a "processing gain" at the stage of the receiver where the signal is despreaded. The resulting signal will have an SNR roughly equivalent to a narrow band (non spread spectrum) signal with otherwise the same parameters. You will have a generally equivalent bit error rate for the same SNR.

It's also possible to receive non spread-spectrum signals below the noise floor, if you can observe it over longer time and get additional "processing gain" that way

Additionally, it is a bad idea to use spread spectrum as a means of concealment because if the adversary is physically near enough, your signal will show up above the noise floor. Due to the inverse square law etc, you have a narrow zone of enough power to be received by your remote recipient, but not enough power for closer adversaries to detect you. You are also reliant on the unlikely situation of an adversary without more advanced RF hardware with lower noise receivers.

Jia Tan could mean literally anything as pinyin since it doesn't have diacritics for tone. 嘉坛 (Jiā tán) could be a totally plausible name, and so could 佳檀 (also Jiā tán). Chinese names can largely use any character that doesn't come with a really bad meaning

How is the location relevant? I think the subtitle of the article presents the thesis clearly: Selling itself as the new American dream, crypto exposes the vulnerable to fraud and scams, and loads risk onto the poor

Time doesn't necessarily have to be another dimension. They're just what they are but organized in time.

How bright do you need the LEDs to be? Even 20 mA is a huge amount for modern electronics. On my boards I have 100 kohm resistors with green LEDs and they are very visible even at some 20 uA of current

I'm perfectly fine with higher bandwidth connectors, but don't force it on the majority of users who do not need the modernity and nice things. Have Type-C as a dedicated high bandwidth connector and don't force me to use it on my devices that don't need the high bandwidth.

I've implemented USB-C with PD and SS speeds before, so I know. I've even used if not that exact same connector, but at least a functionally same one from LCSC.

It's just that these reasons seem so inconsequential to me. There's stuff like type C needing two extra resistors even for USB 2.0. Being able to adapt between connectors is also BS in my opinion because you can convert anything between anything if you really wanted to. And if you only use USB HS speeds, you'll just waste connect lifetime of your expensive higher-specced cable. Sure, you can get 2.0 only type C cables, but why? I think there's no good reason to use USB-C besides high bandwidth purposes. Barrel jacks or supply power better. All our normal peripheral devices aren't consuming exponentially more bandwidth anytime soon.

Comparing technology to human lifetimes doesn't seem very relevant. Even not accounting for broad categories like "fire" or "language", we're still using individual technology from "long ago" like knives, forks, pen and paper, etc. It's fine to make improvements that keep backwards compatibility (more ergonomic scissor should be able to cut the same paper), but changing connector just because it's old is unwise.

The issue of type C is that it's trying to accommodate the entire spectrum of applications from very high bandwidth to very low cost. The range of possibilities has much increased since when Universal Serial Bus was devised, thus many recent solutions feel like they're bad at everything and good at nothing. Perhaps we should allow the specialization of type A as a cheap, reliable, slow, high power, connector, and save type C for only when high throughput is needed?

I think it's a bit ironic that the cable is considered more costly than the receptacle, which is generally true if you consider the device as a whole, but now we have multiple hundreds of dollars thunderbolt cables and the cap on the actual receptacle component is below $10 even for ones with support for higher speeds.

But then again, most people don't have the SMD rework tooling to be able to easily replace receptacles
