I once met a person that never drank water, only soft drinks. It’s not the unhealthiness of this that disturbed me, but the fact they did it without the requisite paperwork.
Unlike those disorganised people I have a formal waiver. I primarily drink steam and crushed glaciers.
This is something HP should have handled.
If a bad update is rolled out then it’s the responsibility of the software maker partner (HP) and the distributor (Microsoft), not just one or the other.
Those laptops are THEIR products, not Microsoft’s.
Both Microsoft and HP have branding on their laptops and a responsibility post-sale for the reliability of their systems. Hardware, firmware and OS responsibilities are all party to this chain of failure.

Perhaps imported and then assembled in Australia?

Ouch
Bad bot. Several of your selected sentences are verbatim repeats.
I wouldn’t know, but it’s totally not on there, or so I’ve been told.
There have been constant news articles coming out over the past few years claiming the next big thing in supercapacitor and battery technologies. Very few actually turn out to work practically.
The most exciting things to happen in the last few years (from an average citizen’s perspective) are the wider availability of sodium ion batteries (I believe some power tools ship with them now?), the continued testing of liquid flow batteries (endless trials starting with the claim that they might be more economic) and the reduction in costs of lithium-ion solid state batteries (probably due to the economics of electric car demand).
FWIW the distinction between capacitors and batteries gets blurred in the supercapacitor realm. Many of the items sold or researched are blends of chemical (“battery”) and electrostatic (“capacitor”) energy storage. The headline of this particular pushes the misconception that these concepts can’t mix.
My university login no longer works so I can’t get a copy of the paper itself :( But from the abstract it looks first stage, far from getting excited about:
This precise control over relaxation time holds promise for a wide array of applications and has the potential to accelerate the development of highly efficient energy storage systems.
“holds promise” and “has the potential” are not miscible with “May Be the Beginning of the End for Batteries”.
Only for certain types of capacitors. In practice they can overlap quite a bit, especially with common aluminium electrolytic capacitors (these form & dissolve complex aluminium oxide & hydroxide layers on the plates).
Oh. Back to resistance: Doesn’t really matter audio quality doesn’t care it’s still the same AC signal just with less amplitude
Only for ideal resistors.
Resistors are noise sources. Intentional resistors tend not to be too bad (and probably won’t be heard in this situation unless you have super-high-impedance headphones, perhaps 10’s of K), but unintentional resistors (eg corroded unstable metal contacts inside a plastic part) can be atrocious.
A few things to add to this:
(1) If your resistor acts even slightly like a diode then you will encounter partially rectified RF signals (more noise yay). Metal oxides between metals can do this, eg if the connector has crimped two badly-plated bits of metal together.
(2) Plasticisers in some plastics can leak out, causing corrosion on unseen internal metal parts.
(Of course linking all of this together is just conjecture, the causes of Moss’ bad adaptors might be something completely different)
learned from experience the differences between using a standard jack and an XLR, and I can say that the sound is vastly cleaner with XLR (at least on a set).
Your experiences were correct, don’t doubt them. That would have been ground-referenced equipment, ie plugged into wires that eventually join a wall. RF interference would interact with that quite differently, unbal vs bal would be quite different.
This could end up competitive.
Invite people to your house, give them a tour and briefly mention the shelf before scurrying them on. Watch their faces contort but don’t give them the opportunity to ask any questions.
EDIT: I have a vague guess at what could have gone wrong with your adaptor. It might have had OK L and R contacts but a broken G contact. You would then hear the difference between the L and R channels, which most often sounds like garbage. Music would be weird (entire instruments/vocals disappear) and mono audio would be silent or near-silent (so you’ll have to turn it up a lot and will hear noise).
Balanced will reduce noise (in terms of RF noise, of course) significantly better than unbalanced,
In this situation I don’t think it will at all.
I don’t think that balanced vs unbalanced is actually electromagnetically that different in this particular configuration (see my edit at the end of above). Things like where the wire is sitting on your body and what pose you are in will probably affect RF noise pickup levels on the headphone wires much more than changing between bal & unbal signalling.
but the source of noise does need to be far enough away from the capturing device to not affect it directly and, therefore, be able to be negated by the balanced cable.
I didn’t get into near-field and far-field effects. I’m not sure that it really matters here, but I might be wrong.
That’s really weird o.o The adapters should just be metal and plastic, same as the cables.
Maybe they have a really weak connection internally, ie high resistance? This might lead to both lower volume in the headphones and (in some circumstances) higher noise, especially if it’s an unstable resistor.
I recommend starting a shelf of cursed items :)
I don’t like adaptors, as they almost always noticeably reduce audio quality.
Huh? 3.5mm to 6.35mm adapters, the small bits of metal and plastic, or are you talking about something else?
I wouldn’t say placebo. It’s definitely doing something.
I would say this is still a placebo. Placebos always still do something. A sugar pill tastes sweet and modifies the sugar levels in your blood. The important questions are validity and effectiveness, not whether or not it does something.
Balanced audio will not eliminate noise in most of the circumstances where a headphone user hears noise. There are far more likely sources (the source file itself, DAC limitations, audio amp limitations, external sound from their environment, etc). It will help in some very specific circumstances, but that’s like trying to sell snow chains to all car owners on the planet because you can claim that they improve traction.
If you do work in an environment where changing to balanced headphone signalling helps… why are you working with your head inside an RF hazard zone?
(From page): However, balanced audio does a better job of eliminating noise, should it exist in your signal. In a case where extraneous noise is present
Misleading.
Noise exists in all signals. Balanced audio only “does a better job” in circumstances other than what this product is being sold for. Discussing this at all gives it false merit anyway.
EDIT: Giving this some further thought: balanced and unbalanced signalling is mostly moot when you’re an isolated device with one cable attached. From an RF standpoint you’re not forming both halves of an antenna (dipole or monopole+ground). Electrically they both look extremely similar in this scenario. Your partially conductive human arms waving around will probably couple to RF noise better than the headphone cable.

A good search term is “SSD over-provisioning”
The file size discrepancy is usually due to 1000 vs 1024
No, that’s something else entirely. It doesn’t matter what measurement system you use, the drive juggles more sectors than your OS can see.
but filling the drive with random data until its full should wipe the drive.
Only if you assume people can’t access the reserved/unallocated/over-provisioned sectors. If you are only worried about small thieves then this might not be an issue. If you’re handling sensitive data (like medical records for other people or anything with sensitive passwords) then it’s completely inadequate to leave any form of data anywhere on the disk.
I assume you’re joking, but if not: the 4MB of flash you see is not mapped 1:1 with 4MB of actual flash on the SD card. Instead there might be something like 5MB, but your OS only sees 4MB of that.
The extra unallocated space is used as spare sectors (sectors degrade and must be swapped out) or even just randomly if it somehow increases IO performance (depending on the firmware).
Erasing the 4MB visible to your OS will not erase everything, there still may be whole files or fragments of your files sitting in the extra space. Drive-vendor specific commands can reliably access this space (if they exist and are available to you, which they mostly are not). Some secure erase commands may wipe the unallocated space but that’s vendor specific, not documented and I don’t think even supported over the SD interface (although I might be wrong on this last point).
Encryption and physical destruction are your best bets.
Poor AutoTL;DR bot has no chance distinguishing the human-written and bot-written parts of the article
At least with current revisions.
I’m vaguely lead to believe that HDMI’s backwards compat with DVI-D (ie why you can have a passive cable from DVI-D to HDMI) means you can use DVI-D signals and an “HDMI-cable compatible” connector. Not sure what this project does however, perhaps it interfaces with pre-made proprietary HDMI logic blocks.
Windows update fetches all sorts of things now. If the hardware advertises X device then Windows update will check if it has anything for it. Approved vendors can provide all sorts of guff. Historically that has included drivers that intentionally brick your devices. HP probably packaged up some software that updates the BIOS and got it into the Windows Update DBs.
