Comment Exhaust (Score 4, Informative) 112

Looking at the video, one issue is readily apparent even to a layperson like me. The engine exhaust is totally exposed. You can see the round nozzles and jet plume totally exposed, which makes it very easy for heat seeking missiles to identify and track the heat source.

The F-22 in comparison has rectangular ports with vectoring for the exhaust with radar-absorbing materials hiding the hot engine surfaces.

Here's what I'm talking about with the F-22.

Then the J-35 in comparison, where the engine nozzles are totally exposed. They don't appear to be vectored either.

Basically what this means is 1980s heat seeking technology would have no trouble shooting down that jet, especially air-to-air launched from behind the J-35.

Comment 50 years ago (Score 5, Informative) 52

Confusing article and even more confusing summary. At first I had the impression that the satellite just moved recently. However the satellite was moved around 50 years ago in the mid 1970s. They just don't know who moved it or why, because the EOL move did not put it in a safer position relative to other orbits.

Almost certainly, it was commanded to fire its thrusters in the mid-1970s to take it westwards. The question is who that was and with what authority and purpose?

Both the US and UK had dual control over the satellite, and at times people from the UK would come to the US control center as well, and they think maybe it was moved then. However records are incomplete, which is really the crux of the matter, because there isn't a record saying who moved it or why.

The official, though incomplete, logs of Skynet-1A’s status suggest final commanding was left in the hands of the Americans when Oakhanger lost sight of the satellite in June 1977.

My guess is they were just practicing moving things and using it up its remaining fuel in the process, and perhaps hardware testing as well (making sure the thrusters still functioned after so many years in space, etc).

The odd part is that phones that have been in policy custody for quite some time (and pre-iOS 18) have been spontaneously power cycling, thus putting them in the BFU (Before First Unlock) state, which is a much more secure and difficult state to crack than AFU (After First Unlock). You know, how that first unlock of your phone requires the pin, but subsequent can use face ID, fingerprint, etc.

When law enforcement confiscate a phone they try to keep power to it so it never goes back to the BFU state, giving them a much better chance of hacking into the device.

LEO was assuming that recently updated iOS 18 phones (IE the cops' own phones) were somehow communicating with offline iPhones in their possession and telling them to do a power cycle. This doesn't really make sense because some of the iPhones were in faraday cages.

The only thing that makes sense is that Apple has had this built into the OS for a while now, but for whatever reason it only started functioning on some specific date.

Simply because he is a horrible person. I am dead serious: I can't find one positive thing about him, as a person. And, believe me, I tried.

I'll give you one that any true Democrat should love. In 1995 Trump opened the Mar-a-Lago club to blacks and openly gay couples. That was the first Palm Beach club to do so and pissed off a lot of rich people.

Trump used Mar-a-Lago for a private residence for a decade before opening it as a private club. He was a pioneer, of sorts, in Palm Beach by opening it to Jewish people and African Americans.

1) IQ is a gaussian centered around 100. So effectively half the population is below average intelligence and will not understand or grasp at complex electoral programs, and they are weak to populist trope or soundbites.

The lowest income tier of Americans significantly vote Democrat (58% of those in the lowest income bracket, vs 36% of them vote Republican). These are the individuals on welfare and government aid that are unemployed or unemployable (which is why they are in the lowest income bracket obviously). Those are also the most uneducated of Americans as well (and education levels correlates very highly with IQ).

Your argument that people only vote Republican due to IQ is incredibly biased and flat-out wrong. You can ask Elon Musk about that. If anything your argument works against Democrats more than Republicans based on factual demographics like income and education, both of which are highly correlated to IQ.

According to your definition, Buran wasn't a clone of the Space Shuttle either, because NASA didn't have a patent on space-plane-looking craft designed to operate in some extremely specific manner. Never mind that some other country did all the R&D, engineering and flight testing to prove the design was feasible in the first place.

Give me a break. You know the situation has become desperate when they must copy a design to this degree. What I'm really curious about is if China bothered to make their own mock-up, or if they just bought a model off Amazon.

Comment Beam pattern is too perfect (Score 1) 187

I think the issue here is that the beam pattern on LED lights is too perfect. The top edge of the beam is a sharp horizontal line on modern lights. So if you are looking at the light and your eyes are above that line, the light looks dimmer than ever before. That's good. The problem is if the oncoming car is angled upwards, like cresting a hill, and your eyes are below that line, you get the full brightness of the lights in your face. Which is brighter than ever.

With older non-LED lights, there was a gradient as the light intensity gradually dropped off over that threshold. So if car crested the hill, you would get more light in your eyes, but not 100% of the light. Further, the gradual gradient made the intensity gently increase and decrease. With LED once you cross that threshold it is instantly brighter, almost like they flashed their high beams at you.

The solution may be to reproduce the gradient threshold with LED lights, so that if a car is angled so the light is in your eyes, you aren't getting the full brightness flirting around the margins of the threshold.

Comment Re:Since the problem has been identified (Score -1, Offtopic) 78

There are other factors as well. In the past the US has literally paid other countries to dismantle and destroy various kinds of weapons in their arsenals. Additionally the US has destroyed their own weapons in parity with other countries (like the USSR), with inspectors from both countries verifying that both countries did indeed follow through with the agreements. Both are forms of global disarmament that, unfortunately, costs (in money and / or lives).

This is really no different - every dollar spent in Ukraine is resulting in the destruction of Russia's military machine. A great number of vehicles, aircraft, munitions, etc, destroyed will never be replaced, as Russia is relying on their cold war inventory of military equipment funded from the surge of spoils from their victory in WW2. Considering Russia's only real source of income is oil and natural gas, which the world is steadily moving away from (and accelerated by Russia's invasion of Ukraine), Russia will not have the ability to ever replace these weapons. At least not for many decades to come.

I have seen a number of military and political analysts stating the the USA has never had a better opportunity in history to get more bang for their buck in the destruction of an adversary's military machine than this situation in Ukraine. Russia will be defanged for a long, long time after this. If it wasn't for their nuclear arsenal as a deterrent, they would be open for invasion as their military has been shown to be weak and inept, in addition to having their best personnel and equipment gutted.

Historically this will be looked back upon as a great shift in Russia, similar to the collapse of the USSR. When you see Russia relying on munitions, and now actual troops, from North Korea, you can get an idea of just how bad their situation really is. Imagine the USA having to rely on weapons scrounged up from Mexico in a major armed conflict. That's pretty desperate.

Comment Just the beginning (Score 1) 284

Oh this is just the beginning. This kind of thing is going to happen more and more. The world is more interconnected and communicative globally than ever before, to the point it's a bit hard to comprehend the difference from just 30 years ago. Having entire new generations of non-English speakers exposed to English at the level they are now is going to result in more and more influence on their native languages.

The world feels like a smaller place, even within the USA itself various regional accents and uniqueness are on the decline, and this is happening on a global scale as well.

Comment Not in a vacuum (Score 1) 142

Unfortunately these days, very few of us are coding in a vacuum. When's the last time you started coding and whatever you were creating was 100% standalone and did not interface with anything in any way? No APIs, SDKs, libraries, web services, etc. The only time I find myself doing that (and still there is at least a tiny amount of interfacing) is coding in C++ for microcontrollers (like ESP32 type embedded stuff).

The rest of the time we have to continuously interface with 3rd party stuff, and that, more often than not, is jumping through a bunch of arbitrary hoops that some random person decided to come up with. For me one of those latest things was updating my code that interfaces with Firebase Cloud Messaging to push notifications to my Android app, because Google deprecated their previous FCM API about a month ago (and now it's on "v1", even though there were previous versions... go figure).

After checking some examples, etc, I couldn't find all the details I needed for my particular target language, so I turned to ChatGPT for help generating the necessary JWT auth and it did a great job producing some boiler plate code that would function. For some reason various online examples I encountered weren't quite right.

So for me, AI has been really useful to help figure out very specific interfacing issues with webservices, APIs, etc, when needed. It does the work of trudging through books' worth of documentation for one specific thing I need to use as some small but necessary prerequisite. Imagine if in order to use your cell phone you need an understanding of the engineering of its internals - that's practically what's involved with utilizing some 3rd party assets, which is overkill.

As for actually writing code, well that is pretty bread and butter stuff after 40 years of it, and for me is the actually enjoyable and easy part.
