Re: $ to pound £
I was going to post the same thing about exchange rate.
It seems if you divide all numbers by 2 you may get a little closer to reality.

Jim Handy writes that the expectation for Optane SSDs was that “the new memory should have performance close to that of DRAM and a price close to that of NAND. Instead, what Intel has announced is an SSD whose performance is close to that of NAND flash at a price that is close to that of DRAM.”
This, added to the fact that it is only avalible in 16GB and 32GB sizes, is why I can't see optane being used. If it had a speed between SSD and RAM, then some poeple could justify a cost between the two. As it stands this is a dead duck. A samsung NVMe SSD is already limited by the speed of the four PCIe lanes it has the Optane disk only has 2 Lanes so I can't see how it can match performance, and is avalible up to 2TB.
When I first came acrros the Optane term I did a google to find out what it was, but could only find marketing misinformation about it, so was sceptical, now I know it is useless.
Exactly. I have a kid who I have to look after in the evenings. I can't just clear off with a days notice and expect my other half to cover. When the people who downvoted me finally get out of short trousers they might understand the issues about having a family and the accompanying responsibilities that outweigh any job requirements.
I agree, I have a wife and kids the I love. They are more important to me than being a slave to someone else.
I'm way too much of a control freak over my data and services to be comfortable with this although I know that problems of scale and to some degree reliability go away. I'd want these alerts so at least I can be informed about the health of my cloud services. I really can't imagine shrugging my shoulders and telling the boss "dunno mate, it's Google innit? Nuffink I can do squire. Nope, no idea, they haven't said anyfink."
Although I agree with you. I am finding that after moving some stuff to the cloud when it goes wrong you can just say to the boss "dunno mate, it's Google innit? Nuffink I can do squire. Nope, no idea, they haven't said anyfink." and he just accepts it at face value, and I can forget about it. although you may need to add, "no, there is now way to contact them, what would cost more. You just have to wait until they fix it." more stress free, but they may not be needed my services any longer soon.
zfs isnt as flexible as btrfs IMO eg Cant remove physical extents and rebalance. btrfs is the default fs in suse. and apt-get automatically snapshots every upgrade and you can rollback or co-exist even version upgrades although it requires command line to do so. I doubt ZFS even comes close on that score. Pretty awesome.
ZFS can now remove devices
at least 6 years ago opensolaris, you could do a upgrade, it would automatically snapshot the rpool and reconfigure grub for the new OS, but give the current one its own boot option for the kernel and a clone of the root filesystem pre upgrade that you could easy boot back into as if nothing have happen. (only gotcha was then manually upgrading the zpool verison on the disks that could not be understood by the old system).
So ZFS can do the automatic snapshot and stuff, just needs to be implemented by the distribution.
"¹ Sorry, I'm part Scottish but I live next to the Alps. A mere thousand metres does not register as a "climb" around here², unless it's properly vertical.
² In seriousness, latitude does make a huge difference, and the weather at Ben Nevis is comparable to a much taller mountain in the Alps, but that shouldn't stop me from taking the piss.
Nope, they where Climbers. They had just got the the top via the north face. i.e. vertical Ice climb.
This is why the "small" startup companies can succeed. The big incumbent might have all the advantages on paper like the customer and the data, but the small start ups that do the IT in house have the "agile" capability to deliver and win all those customers.
"What you do, is go to the customer and ask them, and that's your metric. And, if more numbers happen to help them understand what a great job your doing, to make them happier then fantastic, if not don't. If your saving your own cost, which is sensible, don't confuse it with making your customer happy."
This is it, it should be about providing the product a customer wants, and instead of month of marketing making it up, you release a prototype. Then fix and develop the customer want improved and forget about the features you guessed at but they don't use. The quicker and smaller the release, the less the customer is annoyed by the changes (only as a general rule.) and major bugs can be fixed quickly.
You don't get better at something by not doing it.
I've just noticed that the tiles that are already shaded spell GCHQ in morse code.
Nice touch but probably useless to the puzzle. Unless it is a clue for the next stage."
You're right, I wondered why some of the easy lines had stuff in them. It only spells GCHQ though, so probably just to humorous way to give a clue on what to do.only spend a few minutes so far as my day job is getting in the way.
I ran postfix for 6 years with no problems. (except the odd SDSL connection failure)
Then Exchange on premise for almost 3 years, had about a week of issues, slowness and outlook connection problems (e-mail still moving fine, 99.85%, only a problem due to load in office hours) due to migration to newer hardware but performed worst.
Office 365 for 3 days, and already 3 hours of problems. 96%
That's progress for you.
It will store the files twice, a link to them appropriately. The de-dup table must be able to take both locations of the same hash though as the older flecther4 hashing algorithm used just for checksum would cause problems if de-dup turm on for that pool.
more info can be found at https://blogs.oracle.com/bonwick/entry/zfs_dedup
Trust or verify?
If you accept the mathematical claim that a secure hash like SHA256 has only a 2\^-256 probability of producing the same output given two different inputs, then it is reasonable to assume that when two blocks have the same checksum, they are in fact the same block. You can trust the hash. An enormous amount of the world's commerce operates on this assumption, including your daily credit card transactions. However, if this makes you uneasy, that's OK: ZFS provies a 'verify' option that performs a full comparison of every incoming block with any alleged duplicate to ensure that they really are the same, and ZFS resolves the conflict if not. To enable this variant of dedup, just specify 'verify' instead of 'on':
When FTTC was first being used it was advertised as up to 40Mb or 80Mb, but it was rare to get that actual speed, so I believe ofcom forced ISP to advertise it lower to increase the number of people getting the top speed. the tech never changed so if you are right on top of the cabinet and have a good new copper phone line, then real limit can still be 80Mb.
Erm.... what exactly do you think "the cloud" is made of, then? A cloud provider is essentially an external provider running your data centre. It's implausible to think that cloud providers are running everything off physical servers not virtual ones, so any cloud provider is just a potential client for VMware. And data stored 'in the cloud' is still physically stored somewhere, and given ever-increasing data volumes, it's unlikely that storage providers will become obsolete.
I don't think the big cloud providers are going to go to Dell, EMC and VMware for their needs though, The likes of Google, Facebook and I guess Amazon (don't know about Microsoft) design and build their own hardware and cut of the middle men and go straight to Intel, Western Digital, Seagate etc..
"As for certification. I looked at it until I saw the cost. Never been certified, never been asked if I have them. Only ones they benefit are MS and the people floggin them."
Nope, lack for certification can also be a reason not to give a pay rise / promotion, if you do get certified that have to come up with another excuse.
Companies that really need 100% uptime will still need there own IT (e.g. like hospitals and Data centers have UPS and generation capability) or time some of these will get decommissioned because of the cloud's reliability, (e.g. like the decommissioning of the London underground power station) and then complain bitterly of the very rare outage that takes service out, despite it still exceeding SLA's.
Still have 241 jobs advertised in just the UK, everything must be fine.
He'd have to make sure no one ever touched or he be busted.
Growing u pin the UK I could not tell the difference between an air pistol or a real gun, but I would know he was lying about the next bit
"Workmates said Hillyer claimed that he that worked for the intelligence and security services who had issued him a gun."
If that was true, he would no brag out it, or even tell anyone, and definitely not show anyone a gun. The security services selection criteria is very strict and amounts to one very good candidates in almost every aspect failing one just one aspect. e.g. Giving away information to a potential women, can't find the exact link at the moment, but the role of a honey trap is detailed at http://www.telegraph.co.uk/history/world-war-two/11110440/Agent-Fifi-deadlier-than-the-male.html
"The problem with that is a company doing a good job at a fair price could be out on their ear with no notice when a rival pops up and says they can do the same for half the price, & then doesn't and charges more for uncontracted extras"
This is true but they should at least be able to do the basic job for the price they claim, and not take the customer to court because they can't. BT is the supposed "expert" so should be able to estimate the cost to do they job. The council (customer) should not have to legally responsibility if the supplier is lying to them.
This is going to be good to watch. Not sure it is going to be good PR for BT to send out, if we fail to meet the contract terms well will take you to court if you legally end it.
Cllr Andrew Wallis claims BT failed in almost every area, and sure only some failures are needed to be able to pull out. http://www.cllrandrewwallis.co.uk/cornwall-council-tries-to-pull-the-plug-on-bt-cornwall/
"Why would anyone want to be a teacher, let alone an IT teacher".
In the UK those who want to be teachers are motivated by seeing children develop grow in there understand. If financial reward is what you are after UK teaching is not for you. Even then the bureaucracy (now too much box ticking and measuring) can make a good teachers life miserable so they leave a profession.
Those who think yes are making the same mistake Microsoft where making years ago when Windows 7 came out.
Over time the desktop is becoming more of a niche product and the OS the client device runs is becoming less important, as there is real competition in the client device market at the moment.
GNU/Linux is now the basic main player, and other OSs have to offer a compelling reason to be used instead. Which Windows and OSX do on the desktop etc...
"Although. I know that it still breaks that whole unix thing of "do one job and do it well" but so long as it works well and isn't causing any major problems for you by being combined.. does it really matter?"
Thank you for your response, sounds a lot like the opensolaris smf, just a little different when it works.
I do find with the opensolaris smf stuff though if a simple restart does not work finding out why (past the smf logs ) escapes me.
Haven't really look at EL 7 or Centos 7 yet, I suppose its time I did. Currently the commercial software I administer that runs one Linux it certified for particular 6.x releases. I just haven't felt the need to get my head around systemd as I cannot see it bring me any benefit.
How have others found systemd?
Ever had a child? They're handy devices and you'd be surprised at how easy it is to drown out the sound of crying (though it doesn't seem like it in the dead of night).
For example: you've put them to bed. You've gone downstairs and into the kitchen. You need to cook and you put on the extractor fan and it's quite loud. You could turn it off, but then you'd need to open a door or window because the heat, moisture and smells build up as you cook. Also, to stop it spreading around the house generally, you'd close the door to the kitchen. That's enough to drown and muffle the sound of whimpering or crying.
Got 2 Kids thanks. We eat with the kids before they go to bed, but in your example but you can still open the door every 5 minutes an listen out for them, if you are doing something noisy that would drown the sound out. But even today, in our new house with closed firedoors that block out the sound quite well, they can still wake me at night, of I can hear them above the TV.
I own no multimillion dollar businesses after all.
neither will Rovio soon. A 1 hit wonder being in the right place at the right time, is going to be difficult to replicate. It did have the 3 element of also being a good game ( a requirement, but a minor one to the other 2)
Sun released the code under the CDDL, and FreeBSD adopted it. My real problem is that Oracle then stopped releasing any updates, so the OpenZFS has had to create a fork from the last Sun release of opensolaris. This fork will therefore be incompatible with the later version of Oracle ZFS.
"Just planning this kind of thing will be a major project which will require external expertise."
This is why oracle will be safe for a fair few years, I bet they will ultimately decline like IBM, because of current business model of screw all the current customers. Larry doesn't care about that far in the future, he wants his boats today.
I used to like slashdot, as about 1% of the comments where thought provoking, and the mod points system helped to find them, but that was in the days when about 25% of the stories where interesting. Now only 5% are worth the time to even read the copies and paste "summary". I still look occasionally when I am bored.
You could just not make the headline a question, rather than using opposite question to try and avoid Betteridge's Law complainants. e.g. Uk.gov: Thinks it is not doing enough to promote Big Data.
Also isn't Big Data, just the marketing speak for Data warehouse. Like "The Cloud" is for visualization.
