Good idea - good comms
This is a damn good idea.
The Stratford site has excellent transport links of course (including the International station).
Also very good comms were put in for the Olympics - I remember meetign wto BT techs happily terminating rolls of CAt5 out in the sunchine in the Olympic Park during the Games.
I thought that the Olympic Press Centre was slated for use as high tech offices anyway?
Developers developers developers
Last year Google had 400 million Android activations in 2012, now it's 900 million. "We couldn’t have got there without developers."
Did he bound aroudn the stage screaming Developers! Developers! Developers! when delivering that statistic?
Seems like a missed opportunity....
Re: Welcome home Commander.
What you said.
Reawakened my interest in space.
Beer, as Cmdr Hadfield hasn't had one in six months.
Re: Must ask
Chickpeas? The bloke is living inside a converted plastic water tank. Which will be almost airtight. And you expect hom to live off CHICKPEAS? Its dangerous enough living on storm-lashed Rockall, without the risk of suffocation.
Storage California - you can Check Out but you can Never Leave...
Regarding your point about backups, you don;t back up huge amounts of data in a big store like that.
You keep two (or more) copies, hopefully in distinct locations.
Sorry if that is me appearing to be aggressive - I run an HSM system, and backups consist of backing up the 'stub' files on disk. you then keep two copies of the data on the slower tiers.
Sorry to say it - this is a pretty scrappy article. Not well thought out.
You leap about between discussing object stores, and then comparing them with the underlying technology - you mention 'tape' several times. The actual mechanism for storing the data is separate from the data.
I was at a talk recently by DDN and was very impressed by their Web Object Store.
Similarly a lightning talk by Hitachi at Cloudcamp on object stores. It is an idea whose time has come.
Re: The board has rounded corners
Rounded corners are so it fits into an Altoid mints tin.
Those tins are the traditional case for US breadboard electronic projects.
Re: Hands up, who's not heard of HL7 (another set of standards from the 1980s)
Look at the history of HTML and the Web - at the time there were office systems and information retrieval systems which ran on individual platforms (IBM Profs for instance).
Berners Lee developed the standard for exchanging the information - and produced DEMONSTRATION web browser and web server instances. You DIDN'T have to buy a NeXT computer to use the Web - allt you needed was something which parsed and displayed HTML.
Nail on head
I used to work in a teaching hospital, at the time when the NHS IT project was starting.
I completely agree with this article.
Re: Whats the I/o?
SirDigalot, your comment about a power station is right on the money.
There is a lto of discussion on supercomputing lists re. the push to exascale - not because the compute power is impossible but because of the power requirements.
Re: Can't wait for the software!
Yes. but the problem is getting that retail sales data/industrial sensor data into and out of the GPUs.
You still have to have a very capable system which can read the data from disk and display the results.
Just throwing lots of flops at a problem isn't the stotal solution.
Don't simply blindly expand the capacity of disk on your SAN.
If you are dealing with big datasets (and I do) you should look at a Heirarchical Storage Management system.
You can select a secondary tier of cheaper SATA disks, or a tier of MAID (didks which automatically idle down when not used) and a tier of tape in an automated library.
Less often used data will be pushed to tape automatically.
Re: And how do we get at the existing stuff that's buried in various sealed sites?
Well then - why not build the new molten salt reactors on these same sites?
The sites are already there, and have experienced staff nearby, plus the waste does not have to be transported over a long distance. Existing sites will also have the high voltage generator sets and transmission transformers/wires too.
"And the business based in High Holborn London. "
"Recruitment is a challenge"
Well there's a surprise - everything OK for those at the top who are drawing large slaries and can afford that nice place in Clapham?Notting Hill.
But you want recent graduates to work for you in central London - are you paying them a decent enough wage to be able to afford to rent a place and afford a Travelcard?
Or are you jsut whining that they won't work for peanuts and live in a shed.
Re: The "minor" option for my degree:
JCL? Z/OS ? I used to do a lot of that - well MVS and VM/CMS when I were a lad!
I agree with you re JCL - it IS a throwback to punch cards - because, err, well, the machine expects to be reading punch cards. I can also use a punch card machine.
Maybe I should revive my JCL and start earning those big bucks!
Hundeds of thousands of unfilled vacancies?
I am laughing myself silly.
So where then is the law of supply and demand - why aren't huge salaries being offered for all those oh so desperately needed people to fill those vacancies?
Re: Don't forget 'sar' and 'ksar' and mpstat
+1 for kSar
Its been very useful to me on many occasions - such as users saying 'my machine was very slow last night' and you can show them a graph of memory being used up or huge network loads.
Beer, because its Friday afternoon.
... but ifconfig still only shows the loopback adapter. This is because the sysconfig networking scripts (located at /etc/sysconfig/networking-scripts/ifcfg-eth*) haven't been updated with the new MAC address.
Probably slightly cowboy, but you can use the udev files to associate MAC addresses with eth0/1/2 etc as you say, then in the ifcfg-eth0 configuration files not use a MAC address - ie once udev has sorted them out you just have ifcfg-eth0 not tied to a MAC address.
Someone will tell me that the world will end if I do this, but I've been happily running systems like this for years.
Re: A few things
"All you have done is spout about your nuclear imaging (a claim that cannot be verified)"
Errr... it is a claim that certainly can be verified.
Damned if I'm going to bother to name the company on here, but its on my CV.
And I worked in the medical physics department at a London teaching hospital for several years, and was the computer manager at a brain imaging unit it the same hospital.
If you think thats unverifaible, so be it.
Re: Medical equipment, don't make me start...
"As regards test results (ie images etc). These are transient because it's generally not the result that's important, it's the interpretation of the result, in conjunction with other diagnostic information that gives your doctor the information he/she needs to direct your healthcare."
Absolutely agree. Very well put.
What we're missing here is the process - a scan is ordered by a clinician, patient turns up at department, and a lot of digital data is gathered. That dat is kept on disk (in this case on a MO disk, if I remember the capacity being a whopping 80 Megabytes).
The data is kept in digital fomat so that a consultant can view it, and interpret it. The consultant will dictate a report with his/her findings. And remember it takes years to train as a radiologist.
It is the report which is the important part, and this should be what you think of as your "medical records" - and should be kept.
I don't see what the fuss is about keeping all that raw data - there isn't the storage room for it, or the need.
The data IS kept for a reasonable amount of time - after all you might be in hospital for months, or be undergoing (say) a cancer treatment. It is useful to compare the tumour size pre-and-post treatment (I'm sure there are many more examples). But eight years later? No.
Re: A few things
Easy for you to say that Anonymopus coward.
" This is why one should never use proprietary formats for data."
Have you ever read data off a brain scanner?
I have - I have worked in medical imaging departments, and for a nuclear medicine company which maintained scanners.
I ahve worked with Siemens and Philips gear, and with GE probably but I forget that.
So you buy a million pound brain scanner, dig out your basement, install it, install a cyclotron next door.
So you're then going to say to the doctors that they can't see the data off it because CTI Siemens provide the data in their own format?
Of course, hat you do is translate that data into other formats.
there is a standard for nuclear medicine images, which I worked with.
Similarly DICOM for other imaging modalities.
Re: Why do we have records then?
Medical images are routinely stored digitally in systems called PACS. You can take X-rays directly on digital plates, and CT and MRI data are of course digital anyway.
HOWEVER if we restrict ourselves to patient notes for this discussion, have you ever SEEN a patient records department? I have. Do you know what a Lloyd-George envelope is?
When I worked at a leadign London teaching hospital well over ten eyars ago, the head of medical physics asked me to get involved in a project some bright spark had to scan int he entire hospitals medical records.
I ran a mile.
I doubt a project like that has ever successfully been done.
Re: @ Film .... there is only one copy of it
I'm sure copying X-rays is possible. Remember however that you would need a high resolution scanner, with a good dynamic range - these things are used to look for subtle changes for diagnostic purposes. Such as spotting breast cancer.
However, having worked in a hospital in medical imaging I have never seen X-rays being copied.
I could be wrong - this may be routine these days.
This is one of the arguments for PACS - in a hospital if you are running a clinic a request is made for patients notes and X-ray films which are brought up on a trolley.
Notes and X-rays quite often go missing, and what happens if a patient is attending two clinics on the same day?
with a digital PACS system the images are available in multiple locations.
Re: Why do we have recrods then?
You are slightly confusing patient records and imaging data.
I'm not sure about patient records, but there is no requirement to keep medical images since birth.
If I recall correctly, for children images have to be kept till they are eighteen.
For adults it is something like ten years.
I'm not sure of the exact number of years - as I said it is some time sonce I worked in medical imaging.
Think about it - do you REALLY expect hospitals to maintain warehouses with the X-ray films your eighty year old granny had taken when she was a child?
Conventional X-ray films were reoutinely recycled for their silver content.
This is a bit of a non-story.
I worked in medical imaging at a London teaching hospital several years ago.
I was responsible for storign and retrieving images om magneto-optical disk.
Remember folks - on those days a gigabit hard drive was considered big, and medical images contain a lot of data.
I haven't seen a drive like that in years, and I doubt they are still available.
Actually, that is an argument for X-ray film - film is an acquisition medium (ie you stick it behind the patient when you do the X-ray), it is a viewing medium - all you need is a bright light to view it and it is an archive medium - stick it in an envelope and you still have it eyars later.
Having sadi that, I am not doubting that PACS is the best way to do things (and I worked on a pioneering UK PACS system at the Hammersmith too).
Film is bulky and expensive because of the use of silver, and there is only one copy of it, so has to be physically shifted around for more than one doctor to have a look at it.
Re: This is down to...
Are you SURE this was a proprietary format which needed IE5 to view them?
It is highly likely that they were in DICOM format, which is pretty universal for medical images.
Re: :Never mind the birds
As a child I lived in the town in Scotland where the huge Singer factory had its own power station.
The station discharged warm water into the canal, which had monster goldfish as a result.
I now work in a building which has a massive lake used as a cooling pond - and yes we do keep fish in it!
Big Iron goodness
Mmm mmm mmm.
Re: Is it me??????
I don't agree with you.
The techniques used to build, manage and run jobs on beasts like this filter down to the HPC machines used by 'normal' business and academia.
Getting stuff on expenses
I used to work for an NHS hospital.
I found it cheaper and easier to go to Tottenham Court Road in my lunchtimes and buy small items like cables and connectors on my own credit card and claim them back on expenses, rather than going through filling out a requisitions form.
Re: Turning off servers at 6:30?
Oh, and another point. A lot of us aren't quiche eaters.
Some of us build and install systems which are used for aircraft engine design and nuclear weapons simulations.
A lot of us run systems which do Real Work (TM) - which of course includes e-commerce, big databases, high frequency trading in the City.
In my case I care for and manage hugely powerful Beowulf clusters which run 24 hours a day, running simulations, the results of which my colleagues will look at over the weekend and on Monday morning. If I were to TURN OFF these machines overnight I would be
a) laughed at
b) out of a job
Re: Turning off servers at 6:30?
Turning off the email servers at 6:30? What a clod this guy is.
I work for a company which has a global presence - we send teams of engineers and technicians all over the world, complete with racks of servers and data comms.
We also have branch offices and dealerships all over the globe, which means we are a 24/7 operation.
I also am very glad to say I work with a team of dedicated, hard working people. I guarantee my office will have people in and working hard at 8pm tonight, same as any other night.
Turn the email servers off at 6:30? Ha ha ha ha. In what time zone?
Re: Effluent temperature
I was a boy in the town in Scotland which had the huge Singer plant. They had their own power station for the factory, which discharged warm water into the Forth and Clyde Canal. The canal was populated with enormous foot long (and larger) goldfish.
Re: True believers
Yes - but the discharge is HOTTER
If you took an intake from downstream of your outtake you would end up heating the same water again and again. There has to be a temperature difference between the hot water which comes from your server room pipe loops and the water which you are using for cooling - too close a difference and you aren't able to transfer much heat into the cooling water. Identical temperatures of course and you can't transfer any.
Talking about VAXes, at CERN years ago the standard unit of comparison was a VUP - Vax Unit of Performance
I THINK a VAX 750 was one VUP, might have been a 780
I'm surprised that an IBM PC is measured in milliVAXes - I thought they would be roughly comparable.
Re: Damn you..
God have mercy on my soul for using that word.
I get your argument re. the amount of CPU power in an average office.
And IB switches are quite cheap these days - see colfaxdirect.com for example
I would conter though with exactly the same argument - CPU horsepower is relatively cheap these days, and it is the effort and wages of the programmers and administrators which is the cost.
So I would say it is better to have dedicated hardware in an environmentally stable room, close to the data. Rather than coping with a mongrel set of desktops, which vary in speed and memory.
Depends on your application of course.
And cloud (ye Gods why did I have to use this word...) changes things - I wouldn;t bother these days to do office level cycle scavenging. Hire those cloud machines by the hour.
At the Sandybridge launch the other day there was a talk by Amazon - their HPC instances when ganged together reached 42 in the Top500
Re: "an open-source clinical image and object management system."
this is not (as far as I know) a medical records project like the NHS project - it is a PACS project, ie allowing remote access to medical images.
You should not confuse the two.
The reply from Sporkinum confuses the compression applied to the image on disk (which may or may nto be lossy - I don't know).
Anonymous coward asked about PCOIP compression - which is the compression used by the remote desktop protocol. Read up about PCOIP - it is pretty smart. It will 'build to lossless' - ie you might see some loss when an image is rotating, depending on how much bandwidth you have.
HOWEVER when the image is stationary - ie like an X-ray image - you will have a perfect image.
Speaking as someone who worked on the first PACS system in the UK, this is really interesting stuff and a good use for PCOIP.
Rather strangely I am a particle physicist who worked at CERN and I now with a Formula 1 racing team.
What do you mean? If you're talking about using the LHC tunnel to race vehicles through, then sorry to say it is (a) too small (b) probably not ventilated enough.
OSX based on BSD
Actually, OS X is not bad, based as it is on BSD
Indeed. Someone please remind Mr Watmore that OSX is based on BSD - which is - errrrr..... open source, no? And therefore easily hacked. Ah well.
Open source "more easily hacked"
Mr Watmore is a senior civil servant. He has gone before a parliamentary select committe and stated that "He insisted the government was committed to using more "open source" software to save cash - but had to balance this with concerns about how easily it could be "hacked". "
This is purely and simply FUD.
Mr Watmore, if you read this please present the eveidence for your assertion that open source software is more easily hacked.
Please stand up and speak at any one of the IT user groups which meet in London and give a presentation to back up the statement you make.
"that a few more people have (access to) geiger counters than back in 1986."
Err... well no not really. 1986 was not that primitive a year.
Ionizing radiation detectors have been around for over a hundred years, beginning with gold leaf electrometers and cloud chambers.
"Geiger" counters as you term them are pretty standard bits of kit in any physics lab, or health physics setup, and were certainly common in 1986.
In 1986 I was a student at university, working at a CERN experiment.
My PhD is in experimental particle physics - so I know a thing or two about radiation detection devices - and I have also worked for several years in a medical physics department.
I really don't like the term "Geiger counters" being used by the media - there are many, many types of radiation detectors, which are relevant to the type and energy of the radiation you are tyring to measure (spark tubes, scintillators, ionisation chambers, Geiger counters, filem dose badges, calorimeters, semiconductor detectors, drift chambers)
What you see on TV are dose meters - which are likely to be ionization detectors.
Tbyte of RAM
"...a terabyte per node is going to be normal with the server chips that Intel and AMD are cooking up for this year."
Very interesting - a reference here would be great. I know Nehalem EX is coming, but not sure they can take that much RAM.
