To be fair, MTBF is not something you can measure in a reasonable time for these kinds of review sites. Far better for this kind of thing is niche-specific youtube channels.

But in any case, what you're asking for here is a prediction of your future satisfaction with a product. It's a non-trivial problem even for the most innocuous purchases.

Will I like Lysol or Clorox wipes more? Who knows, and the reviews aren't going to beat first-hand experience in any circumstances.

Landlines are backed by large -48V battery banks, the uptime on landline phone service is much higher than the power grid.

definitely. although one of the hallmarks in a good photographer is the ability to find the exotic in the mundane.

but now i'm curious how many foreign photographers we're missing out on.

64dB SNR is pretty standard these days for MEMS – you will pay a lot more to get up in the 70s. Good studio mics will be in the 80dB+ range.

what exactly is the endgame with a borderline illegal, obviously non-monetizable service like this?

edit: my mistake - i see you're building a local client, not a remote cache. still, i wonder how you see this playing out in the future.

Re:Writing embedded firmware using Rust on Sunday December 19, 2021 @08:54PM (#29620749)
I'm not sure I agree on the safety aspect - if they only thing preventing unintentional peripheral access is verbosity, that's not really the kind of security that matters, is it?
Re:Writing embedded firmware using Rust on Sunday December 19, 2021 @08:24PM (#29620586)
Why is it this way though - it seems to me like you could create a type that just works like the C code

  struct Uart {
    u8 CR2,
    // etc.
  }
Instantiate it as 'static with some macro that defines where it lives in memory:

  #[mcu::loc(0x1002010)] static UART1 = Uart::new();
  #[mcu::loc(0x1003010)] static UART2 = Uart::new();

And then have it bound directly to the memory locations on the MCU at compile time/link time.

Still learning rust, so apologies if this syntax doesn't make sense.

What is a "small-hoster issue"?
it goes beyond repairability though – look how much apple upcharges for SSD and RAM.

The majority of their profit margin comes from overpriced DRAM and flash storage:

RAM:

  - 16GB -> 32GB: +$400 (+$75 retail)
  - 16GB -> 64GB: +$800 (+$200 retail)
SSD:

  - 512GB -> 1TB: +$200  (+$40 retail)
  - 512GB -> 2TB: +$600  (+$150 retail)
  - 512GB -> 4TB: +$1200 (+$350 retail)
Since you can't upgrade it yourself, buyers are paying more at point of purchase, and a high end machine depreciates significantly more over time. With something like framework, you can buy a base model and upgrade it as needed, and resell value of all models is higher because they can easily be repaired and upgraded.
the point is that healthcare costs have to be socialized – if you put the burden on the employer, you necessarily end up with the US system.
Re:Western Digital HDD boss mentions archive disk drive idea on Tuesday December 14, 2021 @01:08PM (#29555001)
Why can't tape be self-contained like HDDs?

Aside from the fact that most people using tape for archival storage don't want to pay extra for the read/write heads, SATA interface, etc., there is no reason why you couldn't package all these things into a self-contained tape unit with a small flash disk acting as a small cache and directory listing.

You could definitely package such a thing for consumers, for example, but most workloads there aren't a great fit for the medium. Basically the only thing that makes sense is using it for archival and backups.

I thought this was about joke stealing, but it looks like the comedians want a cut for the performance and a separate cut for the writing. In other words, they want more of a percentage on the work that they're already getting paid for.

I would bet money that the donor was obese.

Ah, yes indeed, you failed to include the headline from the article: "Woman Becomes Obese After Fecal Transplant From Overweight Donor"

100%

This is the next logical step for semiconductor companies like AD, TI, etc.

AD doesn't tend to compete on cost, so high quality open source drivers become a key differentiator compared to other companies with lower cost parts, especially as these parts become increasingly complex. A 9 axis IMU with 10 different acquisition and buffering modes, built in algorithms, etc. becomes a lot more tractable if you don't have to write the whole driver from a datasheet.

I love drinking ice water, but I stopped after I found that even when using RO-filtered water in a separate ice cube tray, I was getting getting off tastes in the ice from something that was evidently living in the fridge/freezer.

I don't know if its spores or just odors or what, but I can't seem to get it out of the fridge; I'm pretty sure it's growing on or near the evaporator coils, in an area I can't access.

sorry if this sounds dismissive, but I'm curious - how is this different than using google hangouts or facetime or zoom and doing screen sharing?
It's not though. We don't consider America to have a scarcity of food, even though there are people starving there. Food scarcity happens when a region cannot produce its own food.

Shipping food to food scarce regions is not a sustainable solution to the problem of scarcity.

in that particular case, it boils down to how many you can fit on a pallet. if you get an extra row or column or both, you're now selling 550 bottles per pallet instead of 500.

Or try reading the ethereum yellow paper: https://ethereum.github.io/yellowpaper/paper.pdf

When it gets into the symbolics of the ethereum state machine (section 4+), things get hairy fast. Unfortunately papers like this only make sense once you understand the paper. It's a succinct representation of knowledge for someone skilled in the field, but not a sensible way to teach others about the EVM.

There's tons of little utility features like this that are IMO the core of why people use libraries in javascript, but could easily be replaced by a common library offered by the browser.

Base64/hex/binary conversion, type checking, DOM access shortcuts, etc. etc.

Chrome and Firefox play HDR videos just fine, it's one of the first things I did when I opened the package.

Really miss having FiOS when I lived in NYC. AT&T has some dark fiber on the pole just outside my house but hasn't lit it up.
