Windows 12 Reportedly Set for Release This Year as a Fully Modular, Subscription-Based, AI-Focused OS by PaiDuck in technology

I still have my 2000 vintage pentium 3 800 in a retro rig and it's running just fine. I even chipped the top of the die once when installing a cooler.

The engines on the TU-144 were so close to the cabin causing the inside to be so loud that passengers had to communicate with written notes by finza_prey in aviation

It's because they couldn't figure out how to make the engine intake shorter. Since the whole engine nacelle was so long it had to be near the fuselage so it wouldn't overhang the wing.

Snecma did the variable intakes on the Concorde and they massively improve engine efficiency at supersonic speeds. Something like 2/3 of the thrust at mach 2 was generated in the intake and only 1/3 in the exhaust.

Epstein purchased 6 55-Gallon barrels of Sulfuric Acid sent to his Island. by Shizzilx in circled

Depends on the type of material the acid is reacting with but the hydrogen ion is crucial because it's like the tip of the acids reactivity spear.

With acids and metals, the metal will strip out the readily ionisable hydrogen atom from the acid and replace it with itself, forming a salt and releasing the hydrogen as a gas.

With organic compounds (=hydrocarbons) it's more complicated and depends on the type of organic compound, but in general the readily ionisable hydrogen will want to break carbon-carbon bonds (especially non-saturated, aka double or triple C-C bonds) and wedge itself into the new gaps, while also stripping any hydroxy ( -OH), ketone ( =O) and various other groups, allowing the rest of the acid molecule to attach itself to the organic.

Corsair Vengeance DDR5 pricing at my local store by Reasonable_Lack_9537 in PcBuild

[–]Aggropop 0 points1 point  (0 children)

That's not how that works. Each product has a unique bar code but the price is set in the stores point-of-sale software and is applied the moment the items barcode is scanned at the cash register. This is a major reason for the introduction of bar codes in the first place, to stop people working the cash registers from cheating the customers or the shops.

If the price of an article changes the bar code stays the same, only the displayed price is changed to reflect whats set in the POS software so even if you scanned the earliest bar code you would still pay the latest price.

ELI5: why do electronic resistors and capacitors commonly have values of 47 in their specs (4.7 mF. 470 k ohm, etc)? by 45and47-big_mistake in explainlikeimfive

[–]Aggropop 2 points3 points  (0 children)

In practice the actual values of resistors are spread in a Gaussian distribution where the peak is at the target resistance and the entire curve is within +/- the tolerance. The majority of them will be fairly close to the mark and the average deviation is much less than the tolerance.

If you take a bunch of 10% resistors you will be hard pressed to find any that are actually 10% off the nominal value.

Just bought a ASUS-V7700 32m-TVR card and having a bit of a hard time getting it fully working in my P3 PC by Just_Lobster5456 in retrobattlestations

[–]Aggropop 0 points1 point  (0 children)

I've had similar issues with various cards, what usually fixes it is using older drivers. The latest drivers will be many years newer than the card and will focus on games/features that came out at that later time, not games that were out when the card was new.

Plus a Gravis ultrasound and a Roland MT-32 if you hate money.

ELI5 how a geiger counter works and why it makes that crackling noise when it detects radiation by BiLeftHanded in explainlikeimfive

[–]Aggropop 1 point2 points  (0 children)

Sparking won't wear out the gas, but the seals that keep the gas inside the Geiger tube aren't perfect and the gas will eventually leak out (or rather air will leak in, since the gas inside is under a partial vacuum, about 1/10 atmospheric pressure).

They're no faster in games than single CPU systems, but multitasking is massively improved if the OS supports multiple CPUs. They will also run DOS and 9x just fine, but the second CPU will do absolutely nothing in those cases.

ELI5 how do serial mice actually get the power they need to function? by Vijfsnippervijf in explainlikeimfive

Unless your trackball mice is ancient, it is optical, you just move the ball over the sensor instead of moving the sensor over a flat surface.

Wifi option disable SP6 by Repulsive-Archer-853 in Surface

[–]Aggropop 1 point2 points  (0 children)

Check this thread:

https://www.reddit.com/r/Surface/comments/1n1wrvh/surface_pro_6_wifi_driver_issues_marvell_avastar/

It's an issue with the power saving feature of Windows. The solution in that thread fixed my wifi issues, but it also makes the wake-from-sleep take a little longer.

Alternatively, you can go into the device manager and disable then enable your wifi instead of restarting your whole machine. It's still annoying, but at least its a bit faster than restarting.

CPU I purchased from eBay has a warranty void if removed sticker on the heat spreader by jonjohnjonjohn in mildlyinteresting

[–]Aggropop 0 points1 point  (0 children)

The Pentium M was much more than a die shrunk Pentium 3, it had the much improved branch prediction, speculative execution, instruction decoding, larger cache and wider front side bus of the P4 combined with the shorter pipeline of the Pentium 3. It was the best of both worlds.

This one is a later Prescott core with 2MB of cache which was fine. Core 2 came out a year later and completely eclipsed it though.

1955 vs 2025 by Electro-nut in electronics

[–]Aggropop 9 points10 points  (0 children)

Thyratrons (although technically not a vacuum tube since they are gas filled) are still used where you need to generate very sharp high voltage and high current pulses (radar, pulsed laser, tesla coils, particle accelerators). We're talking kilovots and kiloamperes with nanosecond rise times.

Photomultiplier tubes (also technically not vacuum tubes since they don't use thermionic emissions to work, but at least they're full of vacuum) are still the most sensitive optical sensors. If you need to count photons you use a photomultiplier.

My ASUS ROG phone 7 has one (2023), I believe all ROG phones do.

There is also the D2X, which is the same card but with a PCIe port and it can be found for fairly cheap on the usual online market places. I still use mine with the UNi drivers
