Comment Re:I still don't want it (Score 1) 280

You can likely take a .bat file, rename it to .ps, and have it run just fine. I've never had a problem doing so, at least.

Almost all my batch files, and most of my interactive cmd sessions involve "for" in various ways.

I just tried the following basic "for" statement in PowerShell:
for /d %a in (*.*) do ehco "%a"

I got this message back:
At line:1 char:4
+ for /d %a in (*.*) do ehco "%a"
+ ~
Missing opening '(' after keyword 'for'.
        + CategoryInfo : ParserError: (:) [], ParentContainsErrorRecordException
        + FullyQualifiedErrorId : MissingOpenParenthesisAfterKeyword

So for me at least, it seems highly unlikely that my batch files will work with PowerShell.

Comment Re:M.2 (Score 1) 108

Hell, I've even seen some short M2 cards that fit inside a 2.5" drive adaptor to connect to SATA.

That's because M.2 can carry different things, not entirely unlike USB-C:

Computer bus interfaces provided through the M.2 connector are PCI Express 3.0 (up to four lanes), Serial ATA 3.0, and USB 3.0 (a single logical port for each of the latter two). It is up to the manufacturer of the M.2 host or device to select which interfaces are to be supported, depending on the desired level of host support and device type. The M.2 connector has different keying notches that denote various purposes and capabilities of M.2 hosts and modules, preventing plugging of M.2 modules into feature-incompatible host connectors

Some early or cheap M.2 SSD's use the SATA, the "proper" ones use PCIe (NVMe). Plugging a NVMe SSD into a M.2 slot which only has SATA (like that 2.5" adapter likely has) won't work.

Gah, didn't like that less-than sign in the abstract and I missed it when previewing thanks to distraction. Yay.

Here's the full quote:

The analyzed records have an average twentieth century rate of approximately 1.6 mm/yr, but based on the locations of these gauges, we show that the simple average underestimates the twentieth century global mean rate by 0.1 ± 0.2 mm/yr. Given the distribution of potential sampling biases, we find that <1% probability that observed trends from the longest and highest-quality tide gauge records are consistent with global mean rates less than 1.4 mm/yr.

A 1.4 error range is really low too. That means the number might be 0.3cm to 3.1cm per decade.

You misunderstood, the error is +/- 0.2, so that 1.4 is the lower-end of the range when taking the error into account.

You're looking at easily 1/3 or 1/8th the price(depending on where you live) for non-ECC vs ECC and more capacity.

Where I live ECC costs about 30% more than non-ECC, and with RAM prices being so low these days, this is more than affordable for the extra safety ECC brings.

The bigger issue is with the cost of motherboards and CPUs which support ECC.

Comment Re:Multiple cameras? (Score 1) 81

Can't you just use several cameras?

I have a Panasonic sub-compact camera with a mixed-light setting that that takes multiple exposures of the same scene and processes them together into one properly exposed image.

In this brief PDF they do mention the innovative part, though without details sadly:

Typically, HDR images are developed using multiple cameras or multiple exposure sequencing. The game changing approach implemented here is to create high-speed HDR video imagery utilizing a single camera without time sequencing.

Camera exposure will instead be controlled at the chip/pixel level and then integrated into a high-speed video camera. The resulting HDR capability will be easier to install and operate within the SSC test stands because the entire system will be contained within a single camera; this is a completely revolutionary and innovative means to generate HDR capability with high-speed video when compared with the labor-intensive steps associated with the careful alignment required when multiple cameras are used to generate similar imaging results.

So it seems they have per-pixel exposure control, rather than a full-frame exposure control.

Not sure how that works, perhaps instead of letting the charge build up on a cell and then read all the cells after time T, they time how long each cell takes to charge, and after a cutoff time T, measure the charge of the remaining cells?

The idea being you use the time-to-saturation as a measure of brightness for over-exposed areas, while the traditional charge level for the well-exposed areas.

First thing that popped into my mind, but then I don't really know the area so yeah... may be a very stupid idea :)

If you cannot afford to buy something with cash, then you can do without it.

There have been serious suggestions here in Norway to forbid cash payments for various things. This includes buying tickets from bus drivers, paying at restaurants and for purchases above some threshold (think 2000 USD and such).

The bus drivers don't want to have cash because of robberies, the tax administration wants to make it harder for restaurant owners to cheat, and the police wants to make it harder to launder money.

We're not there yet, but I'd say it's coming soon.

Comment Re:They do. (Score 1) 159

No, not this at all. A lot of people are making this mistake. It's not what the submitter is talking about.

Of course this is not what the submitter is talking about, I never said it was.

The need for high framerate in VR is mainly due to rotation of the head, which is exactly what time warping is good for.

If one were unable to rotate your head and could only translate it, VR wouldn't have the same need for 90+ FPS.

I can't see how motion compensation would do a better job, in fact I don't quite see how it would be any good at all.

So yes, very much "this" indeed.

If one can spell apoapsis and periapsis correctly, surely one can spell "brake" and "braking" correctly.

Can, yes. Will always... apparently not.

For some reason I don't quite understand I've been rather sloppy on break/brake lately. Then again, I write way less English than I used to (it's my second language).

Oh well, thanks for the heads up, clearly I need to pay more attention to what I write.

Why would they perform a braking maneouver resulting in orbit outside Callisto?

Juno is planned to have a very elliptic orbit. It will go close to collect data, then move far away to have time to send the data back to earth. They want to spend as little time close to Jupiter as possible to minimize radiation damage.

Also, the larger apoapsis means they can expend less fuel when breaking. If you just want to be captured, you get as close as possible to the planet and break until you're just gravitationally bound, which will result in an orbit with a very large apoapsis and very small periapsis.

What's so terrible about Bandcamp (which is the digital music service I love)?

They seem to be doing pretty good, they're growing as well as being profitable.

Best part (IMO) is that they also have lots of artists saying they appreciate Bandcamp. Here are some comments from that blog post:

Bandcamp is the greatest platform for independent artists. I am glad to be a part of it, without it getting new fans would be difficult.

We release small independent music compilations since three years here on BC. We worked together with more than 200 artists in these years. The most of them publish their music on BC too. I can confirm: More people buy the music on BC. That is what the musicians say in talks. And even our pay what you want releases have a really good perfomance.

I've bought a lot of really great music on Bandcamp, the artists like it. So yeah, what's so terrible again?
