Comment Re: bit rot (Score 1) 475

I'm not very familiar with ext4 nor lvm, but for me it's the fact that zfs validates the checksums on _reads_, and repairs corrupted data if needed, and that you can configure it to store N copies of each block. These two features work on a single disk (non-raid).

So if you have a single disk, you can set it to store say 3 copies of each block, and when reading the data and it finds that one block is corrupted, it will try to use one of the other two.

SMB services should -never- ever be exposed to the internet, under any circumstances.

If it's like the last SMB issue, then the issue is not that they send packets to an SMB server, but rather get the machine to connect (outbound) to a malicious SMB server, which replies with malicious packets.

This can be done using standard phishing tricks.

This is why one should block outbound SMB traffic as well.

Comment Re:People go to movies? (Score 4, Informative) 142

With today's technology, why does anyone still go to a theater to see a movie?

Maybe because some live in smaller condos where big-ass projection screens and high volume is not an option?

I have a high-end 65" TV and a decent sound setup, but it cannot compare to the big screen experience. So I still go to the cinema for movies I really want to enjoy.

I guess it also helps that live in a country where, for the vast majority of cases, people are not idiots when going to the movies. Oh and the seats are numbered so you know you'll get a good seat if you order early enough.

I find it particularly confusing how a game rated "Mostly Negative" still had the highest sales revenue.

Almost all of it was pre-launch purchases. Game was hyped into the 8th dimension. it was on the "top sellers" list months before launch.

However, many players spent more than 2 hours playing the game, waiting to find all those neat things they were promised, before they realized the game was not what they had been told it would be. And after 2 hours of game-time you can't refund the game anymore.

Others are still clinging on hoping the devs will fix the mess and release the game they showed the world during E3 and whatnot.

Comment Re:They can't dynamically figure this out? (Score 2) 164

The only way to get a correct figure would be to predict how many times I'm going to recompile in the future.

Or it could quote you a range: time remaining with light load, and time remaining with heavy load.

It could also figure out what is "light" and what is "heavy" by your usage patterns.

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 :)
