Welsh Terrier

The Welsh Terrier originates from Wales and was originally bred for hunting fox, rodents and badger, but during the last century it has mainly been bred for showing. Despite this, it has retained its terrier strength of character. The Welsh Terrier has been claimed to be the oldest existing dog breed in the UK according to research. The Welsh Terrier was a latecomer to the British show-ring (being primarily a working dog) and was not officially registered as a breed until the 19th century. It is currently on the UK Kennel Clubs list of breeds that are in danger of dying out, having as few as 300...

@HackToHell I'd go ConEmu personally.

Alex Solon

@Bob, also why does it need to be disabled? (I'm gussing there's a newer version, I'm not familiar with the particular versions

Bob

@AlexSolon Put it this way: disable SSL 2.0 and SSL 3.0. Now.

@AlexSolon ...because it's broken.

It's also about two decades old.

HackToHell

ConEmu is not a shell, so it does not provide "shell features" like remote access, tab-completion, command history and others. ConEmu is advanced console window where you can run any shell of your choice. However, some of these features placed in RoadMap

Bob

And it's been broken for one and a half decades.

HackToHell

That's a deal breaker, it's more of a wrapper

Bob

14:19

And it's now even more broken than before.

@AlexSolon Why isn't it disabled in the first place

@HackToHell It's no more or less of a wrapper than Console2 is.

It also integrates nicely with Clink.

@Bob, what should I use in place of SSL 2.0 and SSL 3.0 for the HTTPS connections to my server?

@HackToHell HTTPS is disabled by default on Apache2

@AlexSolon yeah, no one has certs, that's why

You should run an allowed list for protocols

with only 4 memeory sockets.

qasdfdsaq

$35, ech.

Hennes

14:26

I got 3x4GiB and 3x2GiB

qasdfdsaq

I was thinking of selling mine but not worth the time for $35...

Hennes

Decent new board around EUR 275

For that price I might just as well get a new board and new CPU

Alex Solon

@HackToHell, I was going to run my server with a SSL Certificate that's free from this one place (I think @Bob referred me to it, right?), but I think the Certificate is - legally - only valid for non-profit sites, or sites with a certain income range (I haven't looked into that part quite as much yet)

@AlexSolon No. Someone else linked letsencrypt.

Hennes

Not sure.

It started 3 or 4 years ago

Journeyman Geek

quick visual inspection for bloaty caps might help

the ones that could fail are through hole so replacing them isn't too hard

Hennes

Then yesterday I took it out of the case. Cleaning it (carefully).
Added only 6GiB, the 'new' X600 graphics and the old SSD from the RAID array.

And it just booted

Apparently the HW RAID card does not do interesting stuff with a JBOD disk

And after being up for an hor it rebooted when asked without delay.
Which is unusual.

Alex Solon

14:30

@Bob, oh well. It's a damn good service though. Any site that will give you a valid SSL certificate for free is a good one, especially seeing as the usually cost upwards of $50 for a private server. I think how they're funding it is through the standards companies (ISO, ANSI, etc) and large security corporations giving them funds (or the SSL Certificates themselves) in an effort to secure the Internet in a better way.

Hennes

I entered the BIOS, turned off the extra SATA RAID from the motherboard (which was never used but delays booting by 5-10 seconds) and it got stuck in a power on-power-off loop

Bob

@AlexSolon ...nup. even the paid ones are only something like $9/yr on the low end.

Hennes

So I got three options:
1) Live with it.
2) Try again and again. Remove CPU. Reseat CPU. Etc etc. Flex the board and see it it works if it is slightly bend.

3) Or give up.

No spare X58 boards, no spare CPU's

And plety of memory which would be a shame to dump

HackToHell

hmm cmder hangs a bit

Apart from that it's awesome

Alex Solon

@Hennes, if your trying to configure a hardware raid setup to use something similar to JBOD, just use one of the standard setups that are provided by Raid (I think there's a configuration that works very similar to the Windows/Linux software "Raid" implementation).

HackToHell

14:33

Feels like node.js

Ha, you can run a prompt as another user

10/10 gonna use this

Alex Solon

And damn, I didn't realize that SSL Certificates were running for that cheap. I must've been looking at enterprise certificates (or something of the like). Either way, my website isn't bringing in any profits (or any revenue for that matter), so I could declare it as a non-profit organization for right now, and just use the free SSL Cert. from LetsEncrypt. No reason for paying for something that I don't have to - yet.

Hennes

Oh, I got two real HW RAID cards

I like using those.

I had one in use with 1sxSSD (JBOD), 4x 1TB (RAID) and 1x 140GB (15K RPM SAS)

I removed that card to make diagnostics easier.

Plugged in the SSD to the on motherboard chipset SATA port and was surprised to see it boot

Bob

@AlexSolon ...Windows dynamic disks and Linux md both implement common 'standard' RAID levels (amongst other things that aren't described by those levels).

Though, really, standard RAID levels are only general descriptions of what they do - every implementation is different and none are compatible with each other.

Alex Solon

If you're going to have multiple RAID cards, make sure you only have one card in at a time when you configure them, otherwise there's a slight chance that the cards will get confused. Actually, I've also seen it where if you had two RAID cards of the same brand and model, the motherboard would see them as one card (or one as an unrecognized device). So you might have to change the model-ID of one and then force a driver install it

(you can do this in the Windows device manager, just click through the warnings that say it's not compatible).

Journeyman Geek

Assuming he does, and he runs windows.

If ~~I'm not old and senile~~ memory serves, its an older machine. I seem to think it runs fbsd, but I'm not sure

Alex Solon

14:41

@Bob, the way Windows write it's data structures for RAID is completely incompatible with most, if not all, hardware implementations. I think a few of the Linux implementations (keep in mind it's quite a bit more complicated to setup if you're dual booting and want to have shared software raids between two different types. In that case, use the Windows version of the RAID implementation, because Linux is much more likely to support it than Windows is to support the Linux implementation)

Journeyman Geek

and ugh

So much stuff to charge for the trip

Bob

@AlexSolon ... ... "every implementation is different and none are compatible with each other"

It's not "software vs hardware".

Journeyman Geek

spare phone (since our indian sim cards are full sized, not micro), kindle, spare laptop, battery bank....

Bob

It's "this brand of hardware vs that brand of hardware vs that brand of hardware vs that piece of software vs every other implementation out there".

Heck, you're not even guaranteed compatibility between different models within the same brand.

Alex Solon

@Bob, the "Standard RAID Levels" are just descriptions of what the particular implementation must achieve with the configuration (whether that's data parallels, striping, or some other config.), most software RAID configurations are capable of loading the hardware configurations and reading from them (assuming your RAID card didn't do some fancy GPT or identification type stuff), but it will be slower using an

exact implementation of the hardware type. That's why software RAIDS do the same thing in a very different way - in order to gain optimization, and make a software RAID even slightly usable in terms of performance.

Bob

14:45

@AlexSolon ...isn't that exactly what I just said?

Is there an echo in here?

Also, no, software RAID implementations typically are not compatible with the hardware implementations.

Outside of specialised recovery and forensics tools.

Alex Solon

@Bob, that's exactly true with the product identification, but usually it's more of a problem if you run two of the exact same cards. That's why I always use two different models unless the model I choose is capable of running along side a similar/same model

qasdfdsaq

Urgh WTF. Amazon Germany won't ship the laptop I want to the UK

On the plus side, you can by the same laptop second hand on the same page from Amazon and they will ship it to the UK

Journeyman Geek

0_0

Alex Solon

@Bob, a lot of the software RAID implementations can rebuild a hardware raid config if your RAID card died or what not. It's not always guaranteed to work, and the only thing you can be sure of is that it will be extremely slow and processor intensive.

qasdfdsaq

So much for EU free trade and what not...

Still. The second hand one ended up being £150 cheaper than the same model new from the Czech Republic, that being the only other place that sold the specs I wanted.

Sure they've both got foreign keyboards but I'm more familiar with German than Czech keyboard layouts anyway.

Alex Solon

14:49

@qasdfdsaq, you could always try using a VPN to complete your purchase, but if it's a trade restriction between the two countries then it may or may not get "lost" in shipping and you would potentially be out a large sum of cash. I wouldn't take the risk, but it might be possible.

qasdfdsaq

@AlexSolon VPN wouldn't help, and it's not a trade restriction either. Someone ticked the wrong checkbox and Amazon refuses to ship it to UK addresses.

There's basically zero trade restrictions in the EU, that being much of the point of the EU in the first place.

Probably someone ticked "Hazardous goods" because it has a lithium ion battery...

Bob

@AlexSolon As I said, specialised recovery and forensics tools. Not something you actually run it with.

qasdfdsaq

And the restriction is based on destination address, not source IP or anything like that.

Bob

The formats are fundamentally incompatible, and at the end of the day what you end up doing isn't much different from taking a backup image and later restoring it.

@qasdfdsaq Possibly just the airmail carriers refusing it? Though I suppose they could move it by truck.

Here, the only options are air or sea :P

Alex Solon

@qasdfdsaq, you might want to look into companies based in a country that Amazon will ship to. There's some that will receive your package and then send it to you from their country that does allow shipping to the US. Kind of like a loop-hole in the system. I'm not sure if it's entirely legal - or if it complys with the international shipping requirements/laws - but there are companys that will do that

@Bob They explicitly don't have Li-Ion listed as hazardous when you actually click the hazardous list :-/

I just ended up ordering the second hand one (£100 cheaper).

Bob

@qasdfdsaq Ah. It's been a pain in the arse shipping Li-ion here with AusPost refusing it :\

qasdfdsaq

A second-hand, previous generation German version of the laptop I had in December, but for £500 cheaper than I paid for the UK version, not too bad

(And it's meant as a temporary stopgap anyway until new generation mobile graphics chips come out later this year)

@Bob, one of my raid cards died once and I was able to use a Linux implementation of RAID to rebuild the array and then re-rebuild it with the other cards array (they were combined together to create around 15ish Terabytes of redundant storage).

qasdfdsaq

@AlexSolon The thing is the Amazon restriction is completely superfluous. There's no external restriction stopping them from shipping it, it's just an internal don't-care/SNAFU. I'm pretty sure I could have roped one of my German friends into forwarding it to me if I had to tho

Alex Solon

@Bob, it was extremely slow to rebuild the array (it took around 6 hours), but it did allow me to retrieve the data and install a new card.

qasdfdsaq

6 hours doesn't sound slow at all for a 15TB array.

Alex Solon

@qasdfdsaq, if you mean a temporary laptop then I wouldn't bother wasting your money. Just wait

qasdfdsaq

Linux software RAID is faster than most hardware RAID cards nowadays anyway.

Bob

...it takes me about that long to verify a 4 TB array

maybe longer.

and that's just a verification of a mirror

qasdfdsaq

A 1.5TB drive I had would take 5.5 hours to read from start to finish (continuous sequential). That's a best case scenario. The 4TB drives I have take about 8 hours.

Bob

granted, the disks are slow and the impl is shit

@AlexSolon heh, Please don't assume folks here don't know what they are doing

Alex Solon

No no. It took 6 hours to rebuild half of the array (each raid card contained half of the drives). And it took much much longer to reconnect the two array halves together and get the data off

qasdfdsaq

The 8TB drives I have... urgh. 14 hours(!)

Alex Solon

In my hardware implementation I could rebuild an array with two failed drives (it happend) in a hour. But I do have enterprise grade RAID cards

qasdfdsaq

It's impossible to read or write any modern >1TB drives in an hour, it must have been using used sector logging.

Bob

@AlexSolon Hm. Looks like the one exception is that a patchset for recognising Adaptec volumes is available for md. But it's not baked into the core, so you would have had to run with a custom build.

(Basically, we're back to specialised recovery/forensics tools)

Even the fastest 15K RPM enterprise drives in existence take over 1.5 hours to go through 1T.
