Comment Re:Different failure mode (Score 2) 82

My experience is quite different to this - most SSDs I've seen fail have been the flash that's failed, and the drive puts itself into read-only mode so that it won't damage the flash with further writes. This allows you to copy the data off the drive. Interestingly, some failed SSDs report to the OS that they are read-only, but others pretend to be a read/write device, but they silently discard all the writes. At least you can still get the data back that has already been written though.

If however the controller fails, then the drive can suddenly die - and as most drives are using some form of encryption on their flash chips, even if you transplant another controller, the crypto keys will not match and the data will be unrecoverable.

Comment Re:Not enough people that use powershell commentin (Score 5, Informative) 110

PowerShell and it's objects are awesome ... until they aren't.
One issue I face is that I use PowerShell to manage things on Office 365 / Azure AD that I can't do through the web interface. This is mostly good, except when it's not.

An example, if you're running something like Get-MailboxFolderStatistics on a local Exchange server, the statistics you get back are proper objects, and you can do things like sort them by size.
If, however, your run this against Office 365, you get output back that looks the same, except it's serialised as xml, sent down the line, and then deserialised for display. There's no option to tell it to return sizes in bytes, because you don't need to because it's an object and you can display it however you want. It then returns human-readable sizes (e.g. 12.3 GB, 486 MB etc) and now you can't sort it because it comes back down the line as text. If you want mailbox folders, on Office 365, sorted by size, you then need to grab this text, and parse it to turn it back into bytes, sort it, and then parse it again to turn it back into human readable text.

So you then need to do something like:
Get-MailboxFolderStatistics username | sort-object @{ Expression = {$tmp = $_.FolderSize -replace ".*\((.+) bytes\)","`$1"; [int]$foldersize = $tmp -replace ",",""; $foldersize }; Ascending=$false } | ft Identity,FolderSize

Comment Re:Can Oracle be trusted? (Score 1) 51

Solaris was never intended to be an alternative to Windows. Solaris on x86 was a viable to Linux once upon a time, but Solaris on SPARC was where Sun had their sights set, and it was a formidable combination with rock-solid hardware and a powerful operating system that enabled things we can only dream about on the desktop or commodity server space - think about things like hot swap CPUs and RAM, this is possible on Solaris SPARC.
Interestingly enough, Apple built DTrace into Mac OS X. It's utility is somewhat limited these days with System Integrity Protection (SIP aka rootless) but it's still there and can be used without disabling SIP if you're only tracing non-Apple binaries.

And the answer is no. Who in their right mind would use this, knowing that the moment Oracle's lawyers smell the hint of money in the water, they will change the licensing requirements again so that what was once free is now an expensive licence. They have form in this regard, they have done it before, and you're crazy if you don't think they'll do it again.

Once upon a time, Solaris was a solid alternative to Linux on commodity x86 hardware. Today? Not so much. The only reason to use Solaris is if you're in bed with Oracle, and the only people in bed with Oracle are people with money to burn.

Sonos is not supposed to be really simple, it's supposed to be a multi-room, wireless audio system with decent sound and an app controller that allows access to your own music library as well as popular streaming services.
If you want really simple, you'll get a stereo amplifier, a pair of speakers and whatever audio source you want, and you'll listen to it in one room.
If you want convenience, and audio synchronised across different rooms, then that's where Sonos enters the picture. It's not cheap and it's technically very sophisticated. They have good audio engineering driving the sound and, most importantly for me, they give you years of ongoing support without needing to keep paying for a subscription.

There are many other subwoofers that use the same general design as the Sonos Sub. It's notable however that the tech in the Sub (two opposed drivers working in opposition to cancel out the vibrations of the other one) is vaguely similar to this tech that Sonos have purchased.

Comment Re:Huh? (Score 2) 42

This is an interesting development as Sonos already use a similar concept in their compact Sub.
They have two drivers facing each other across the central hole in the sub, firing in opposition to each other.

This cancels out vibrations in the cabinet and increases the displacement over a single driver.

That's absolutely true, and there were other considerations too since color JPEGs are 24 bit and you not only have to decode the image but also downsample it somehow into a number of colors you can display. Doing this poorly can be done a pixel at a time, but doing it well requires loading the whole image into memory... and lots of computers of the day didn't have enough memory to decode JPEGs that they could otherwise [more or less] display.

I wonder what the first retail computer with 24bpp graphics was.

I can't remember there being an option for my 286 to display more than 2556 colours, but for my 386, there was.
I had a Tseng Labs VGA card, and there was a plug-in highcolour DAC available that gave it either 15/16-bit highcolour (32k or 64k colours) or 24-bit (17M colours) truecolour.

I also remember in the 286 days that JPEG (and JFIF) images were uploaded to bulletin boards, but you had to first download them to disk and then run JPEG2GIF to convert them to a 256 colour GIF that the computer could actually display. Many JPEG images were actually created by GIF2JPEG, so although the format was capable of 24-bit colour, a lot of images were simply converted from 8-bit colour.

Comment Re:Fraudulent purchase ? (Score 1) 132

NewEgg state on their website "30-day hassle-free returns". Many online storefronts have a similar policy.
NewEgg specifically say that you can return an item sold with the 30-day hassle-free return badge at any stage within 30 days, with no restocking fees and free return shipping.
It doesn't matter if the dude from Gamers Nexus intended to use the product or not, NewEgg sold it under the condition that it could be returned for a refund in full at any time within 30 days.

Someone buys a product with - apparently no intention of keeping it - fully intending to return it, expecting a full refund.

Why isn't that fraud ?

Why should a retailer be expected to deal with this cynical purchase with anything other than a cynical return experience.

Why indeed? Because NewEgg promised that they would.

Comment Google are the new Microsoft (Score 1) 109

Google are straying further and further from their don't be evil mantra, and trying to take over the free web by pushing Chrome, that they are truly the new Microsoft.

Curiously enough, Microsoft are now the new Google.

Sure, you have to pay for Office 365 email hosting, but it's very, very good. It works better with regular email clients (unlike Google's way they map labels to IMAP folders) and it all just works.

You can mix and match licences, so you may only need one account with a Business Standard licence (giving you 50 GB of email hosting, plus the Office apps) and the other accounts may only need a Business Basic licence instead.

The spam filtering on Office 365 is excellent, and you can easily archive old users as Shared Mailboxes (each with their own 50 GB quota) for free, unlike Google where you have to keep paying for any mailbox you want to keep.

Comment Re:Maybe "deprecate" means something different (Score 1) 68

Kernel Extensions (kexts) were deprecated in macOS Catalina, released in October 2019. They then transitioned to unsupported in macOS Big Sur, released in November 2020.

Now, this breaking functionality in Dropbox is not what it seems on the surface.
I don't know what is actually changing behind the scenes, but the outcome is that Smart Sync (which is what Dropbox calls syncing cloud-only files to the local disk, on demand) is still working if you double-click on a file in the Finder. It's only when you try to open an online-only file in an app (via File > Open) that it won't sync.

So, it's not that this functionality is completely broken, but it's more likely got something to do with securing the way that kexts can communicate with third-party apps.

If you commonly double-click on files in the Finder to open them in third-party apps, then you'll likely notice nothing amiss. It's only if you were to then be in an app, and go to open a file directly that it will fail to sync, and only if it's an online-only file. Syncing of files that are synced locally to the Mac will continue to work as expected.
