Re: @Degenerate Scumbag - ZFS is for dedicated file-servers

>It works, is widely used, and has features like nothing else. Other attempts to match it have not succeeded.

This is true, in the context of its designed purpose.

>It does use chunks of memory, but then so would anything else doing the same job.

The job it's designed for is to be a dedicated storage server, and it uses memory accordingly. It intentionally gobbles up all available system memory, leaving just a small headroom for safety, and unfortunately because it wasn't designed with the Linux kernel architecture in mind, it's not plumbed into the regular kernel disk cache system, and thus won't release that memory as instantly as a native Linux filesystem does.

>Saying, "don't use it", is like saying, "make do without its unique features" and isn't offering a viable alternative.

The OP was advising against using it in inappropriate applications. For all you know they could be a big fan of it in the proper context, as am I. And of course, I'm sure we'd all like to see a similarly functional Linux-native equivalent COW filesystem created, that would play better with the Linux kernel and be suitable for more general applications. (With BTRFS seemingly at a dead-end, Bcachefs is the new hope on that front.)

And talking about its unique features, I'll refer back to your earlier comment:

>Software package management is heading towards using ZFS snapshots. It'll be the way you get software, or uninstall it. It's a pretty neat idea.

The experimental ZFS snapshot functionality that Ubuntu have implemented in package management is merely a "roll-back" feature, ie make a snapshot before applying changes, so it can be reverted to the known good state if things go wrong. This is conceptually similar to what Windows does with "System Restore", by creating restore points before applying updates.

The idea that ZFS snapshots could be used to distribute software betrays a fundamental misunderstanding of the concepts involved. ZFS snapshots are a filesystem block-level feature, and thus a snapshot is only applicable to the ZFS filesystem it came from, or a replica of it.

Re: ZFS is for dedicated file-servers

For one, it eats memory like no other filesystem. The projects itself states that it can be used with 2GB, but 8GB+ is recommended for decent performance. The consensus among major users seems to be 8GB + 1GB per terabyte of storage. Of course, this is for caching, and you could argue that Linux itself allocates unused memory as disk cache whatever the filesystem, but ZFS being non Linux-native code bolted on to the kernel is not plumbed in to that system. It allocates that cache memory to itself like application memory. None of this is a problem in it's intended application, but it's hardly optimal for desktops.

NASA to launch 247 petabytes of data into AWS – but forgot about eye-watering cloudy egress costs before lift-off

Re: me too

Yeah, that's along the lines I was thinking, except racks of up to 48u are available, so you can get 11 of those 4u 60 drive enclosures per rack (you could actually fit 12, but then you'd have nowhere to mount the switch). Also, Seagate are promising to release 18TB drives in the first half of this year, which ups the potential density a bit. Power-wise, you could _just_ manage with 5KW per rack constant power, but only if you carefully manage the spin-up of the drives - if they all start at once, the initial surge would draw 15KW.

Degenerate Scumbag

I'd be curious to know how you achieve that density. My back-of-a-fag-packet calculations made it 24 racks, at a cost of around $10mil. Still, the point stands that this would be far cheaper for them to keep in house.

Other than the fact such action would have traditionally been regarded as extremely bad form that "breaks the internet", I don't believe so. There have actually been several alternative root server organizations, some functioning just as independent mirrors of the ICANN root, some serving kooky non-ICANN TLDs. Some continue to run:

No, it means "If you are stupid enough to buy a voluntary surveillance device and place it in your home, we are not responsible for any data the controllers of the surveliance device gather on you by profiling the searches you make of our content using the surveillance device."

They're providing web content to Amazon in the same way as Wikipedia etc, nothing more. Amazon certainly can profile you based on your searches of that, in the exact same way that Google can gather information and targeting advertising based on a profile of your searches. I absolutely agree that the potential for Orwellian abuse is quite horrendous, but if you're concerned about that the answer is to disengage from Amazon/Google etc, not blame content providers for making their content available on the platform you chose to use.

Row erupts over who to blame after NordVPN says: One of our servers was hacked via remote management tool

Degenerate Scumbag

Re: I dont get how the box itself was compromised

Usually these remote management systems function as emulated local keyboard + monitor, and can mount disk images as virtual USB drives, enabling full remote reinstall of the OS. This can be used to boot a live image and from there you can mount the internal drives and look at what's on them. Access to the ILO is pretty close to having physical access to the machine.

A cautionary, Thames Watery tale on how not to look phishy: 'Click here to re-register!'

Degenerate Scumbag

Do not trust any public announcements from Thames Water regarding any issue at all. There is barely anyone left in the company that actually knows what they're doing, and the customer communication is left in the hands of totally clueless people.

This extends beyond IT issues, and into the realm of operational matters and public safety. One example occurred last year during a burst main event in Hammersmith. They actually tweeted out that discoloured water is safe to drink. (It most certainly is not; they probably meant aerated water, but the people sending these public communication simply have no clue.)

Degenerate Scumbag

It's official management policy in Thames Water to declare any failure a success. Like when they spent £250 million building a desalination plant that was supposed to have a 150MLD capacity, but can barely run for more than a couple of days at 25MLD. Didn't stop then CEO Martin Baggs from singing its praises in a self-congratulatory wank-fest of an opening ceremony.

All Thames Water's customer accounts were centralised on an IBM mainframe decades ago.

The 8chan "global rule" has always been "don't post anything that is illegal under US law". Child pornography has never been tolerated, however because of the free speech principles of the board they won't act against things that are distasteful but legal, such as clothed images of cute kids shared by pedos as wank material. So in that respect they could be said to be tolerating pedos.

Peace pays dividend for OpenWRT as 'baseline' release lands on servers

Degenerate Scumbag

Re: OpenWrt is the only thing I run

Yep, I'm the same, I wouldn't consider running anything else on a home router.

You only have to looks at things like the WPA2 bug last year to see the benefit. How many router manufacturers released patched firmware for their old routers? How many unsupported routers are still out there, permanently vulnerable? Mine were secured within a day of hearing about it.

Degenerate Scumbag

No Damage

It's not really accurate to talk about the "damage done" by the fork. It's not like there were ever really two projects running in parallel.

The reality was there was an active team of developers who were being hampered by the original OpenWRT project infrastructure still being under the control of founders who had little involvement any more, and apparently little time. The active developers forked LEDE through frustration to enable progress. OpenWRT development immediately stalled.

The re-merge was basically a case of the inactive founders finally getting the message and handing over control of the domain to the active, ongoing project.

Dormant Linux kernel vulnerability finally slayed

Degenerate Scumbag

"Well, except when you have Linux on closed hardware (NAS, router)"

This is why for years I have not bought any home router etc without first checking that it's supported by OpenWRT. This policy really paid off last year when that major WPA vulnerability was discovered - all my routers, including 5 year old models were updated pronto. I'm sure that there are millions of vulnerable routers out there that are long since unsupported by the manufacturers, but still in use.

Internet engineers tear into United Nations' plan to move us all to IPv6

Degenerate Scumbag

Re: The reason for lack of IPv6 adopton

Many ISPs provide underpowered routers to their customers that struggle to do NAT at full speed on their fastest services. Ipv6 liberates them from that burden. I personally witnessed a significant performance increase when my 1GBit line was IPv6 enabled.

Degenerate Scumbag

"If the minimum subnet size is 2^64 , and the complaint is "the routers will fill up if we have millions of routes". how exactly are switches going to cope if you put millions quintillions of hosts on one subnet?"

I'm afraid this merely betrays your lack of understanding.

The large address space allocations reduce the number of routes required by allowing things to be properly routed by subnet. This was how IPv4 worked originally, but it ran out of address space for that scheme decades ago.

Here's an IPV4 example for simplicity. Say you have the following ip addresses:

134.240.73.12

134.240.73.89

134.240.56.87

134.116.76.23

Under the present overcrowded IPv4 scheme, a router might well need separate routing table entries to reach all those addresses.

Under the original scheme, it would have required a single entry to reach the gateway for the 134.*.*.* subnet.

The gateway for the 134.*.*.* subnet would then have required 2 entries for the gateways for 134.240.*.* and 134.116.*.*

The gateway for the 134.240.*.* subnet would then have required 2 entries for the gateways for 134.240.73.* and 134.116.56.*

The huge address space of IPv6 allows a return to a similar addressing scheme.

Degenerate Scumbag

Ok, I'll take the bait...

How is a system running 20% of the world's active internet connections not working?

It's not a case of getting ipv6 to work, it's a case of getting ISPs to implement it. The assumption that this is not happening because of some inherent problem with ipv6 is disproved by the many successful cases.

The reason for slow adoption is simple enough to explain: pure corporate inertia. They need a "business case", and ipv6's main selling point is extra address space, which isn't much of a carrot as long as enough ipv4 addresses remain available. It's taken the stick of address exhaustion to get Western ISPs moving.

The lower adoption in developing nations probably has something to do with the fact that their regional registries still have a fair bit of their ipv4 address allocation left unused. It's not rocket science, and it doesn't require UN interference to solve.

Re: Still I don't understand why Russian doesn't allow full tests.

Re: BT

So BT completed the rollout, the problem is with your customer equipment.

I can understand you being frustrated with BT as they supplied you with the hardware (and it seems the firmware updates that were promised for earlier models were not delivered), but the fact is that you do have an ipv6 enabled line. Your problem is the shitty support BT offer for the equipment they supply.

If you were that way inclined, you could probably liberate the router from their proprietary firmware and implement ipv6 yourself - the hardware is perfectly capable.

Degenerate Scumbag

Re: BT

I believe they rolled out firmware updates to devices going back to the HomeHub 4. I can't speak from personal experience, though.

I'm also on VM. I got fed up with waiting and implemented ipv6 with a Hurricane Electric tunnel. It works perfectly and maxes out my bandwidth with ease.

My advice to any VM customer is to switch their POS "super hub" into modem mode and use a decent router behind it. I have used nothing but OpenWRT routers for years. The ipv6 autoconfigures effortlessly if plugged into an ipv6 native connection, and even the tunnel config was straightforward to set up.

Re: Alternative history drivel..

Thanks for linking to that Wikipedia article. It was most enlightening to learn that the electromechanical, binary Harvard Mark 1 was "based on" the mechanical, decimal analytical engine. I'm puzzled though, because the Wikipedia article for the Analytical Engine states:

"Howard Aiken, who built the quickly-obsoleted electromechanical calculator, the Harvard Mark I, between 1937 and 1945, praised Babbage's work likely as a way of enhancing his own stature, but knew nothing of the Analytical Engine's architecture during the construction of the Mark I, and considered his visit to the constructed portion of the Analytical Engine "the greatest disappointment of my life".[36] The Mark I showed no influence from the Analytical Engine and lacked the Analytical Engine's most prescient architectural feature, conditional branching."

Clearly the Analytical Engine article must have been written and edited by people with an ideological agenda to push, little knowledge of the subject matter, and no respect for historical fact.

This must be the case, because I can't imagine the "Women in Computing" article to be the inaccurate one, what reason would anyone have to distort that?

Facebook confirms Cambridge Analytica stole its data; it’s a plot, claims former director

Degenerate Scumbag

Storm in a teacup.

So let me get this straight:

-Data was collected from people who opted in.

-More data was collected from those of their friends who chose to leave their profiles open to the public.

-Trump and Brexit campaigns used the services of this company, so now people with anti-Trump, anti-Brexit agendas are trying to claim it as a sophisticated psy-op that tricked people in voting the wrong way.

-Throw a Russia connection in, just because everything is Russia's fault these days.

Sorry, not buying it. They didn't have to change people's minds. Both the Trump and Brexit campaigns primarily succeeded because they tapped in to discontent that had long been building among the electorate.

The data that they got from this would only have been useful for researching public opinion, which is a legitimate thing to do. If people don't want their data used in this way, they shouldn't publish it to the world on a public website, which is what an open Facebook profile is.

This is an attempt to manufacture a scandal, and it smacks of desperation. It's about time the Globalist lefties accepted that the public are not on board with their agenda.

It is indeed a cinch for those worth their salt. It does tend to rile up the low-iq dead wood who have trouble picking up new skills.

Indeed. If a company has an "ipv6 team", then it's function should only be ensuring the regular network team are fully up to speed and assisting them with deploying the upgrade. Any model of seperate teams is pure idiocy.

Re: Facebook not running IPv4 at all?

V6 is so complicated that my entire home network automatically configured when they activated it on my connection. It was so seamless it took me a while to notice.

The extra address space may be the driving force behind deployment, but it's not the only advantage. Built in multicast has the potential to reduce streaming bandwidth considerably. Imagine being able to stream video directly to a million people from a home internet connection. With ipv6 this is possible.
