  1. Re:Has the NIF... on Record Setting 500 Trillion-Watt Laser Shot Achieved · · Score: 1

    This is the real question, they were discussing this stuff years ago, like it should achieve ignition any moment now. I am hoping they are just keeping it quiet since this one is more of a research facility for future fusion devices. Even if they do get more out than they put in, this thing is not viable as an power plant in any way - containment of that output energy is going to be very tricky, plus it gets so darned hot they have to wait half a day before they can fire it again and I think some of the parts like the huge lenses may be too easily damaged. It will be something like, yes we achieved ignition, but we only proved it, most of the energy went into heating up the facility and melting parts

    Everyone works with cloud infrastructure because its trendy ? Don't try and learn anything, it could be painful. Keep it trendy, that way you don't have to pay attention.

  3. Re:What CS definition? on Ask Slashdot: Building a Personal FOSS Cloud? · · Score: 1

    I agree that it is a buzzword that is thrown around, but when I compare someone wanting a personal cloud so they can share infrastructure across their personal devices, basically to their own VPS somewhere - syncing their contacts, to the gradual advent of transcending hardware constraints to services by automating the sharded location of data and virtual compute nodes to scale tasks out as if the hardware is just a temporary location for some info passing through it. Servers used to have names, now, in the cloud they are scalable service template instances. It's not a buzzword, it's quite a complicated thing that has arisen from the abundance of hardware as a unit and the requirement that none of it be solely relied upon just to provide services. People who work with cloud infrastructure, know that it is the culmination of years of advanced server operations that has luckily made many single server requirements largely irrelevant, The servers are expendable and a machines purpose is transitory, no longer is most of what a server does dependant on its OS being tended like a garden - the OS is important, but what one server does today, maybe nothing like what it does tomorrow, since the entire infrastructure is a like a floating virtual interoperating system. Brought online to do this today and it all goes tomorrow. Many organisations doing this every day to the same big data-centres. The data is not embedded into the co-dependance of hardware and its OS, whole systems come in and out of existence every day. This is why it's a cloud. It's not a buzzword after all.

    At least I told you when I mentioned Openstack, I was talking about cloud services and not the failure of all mobile vendors to implement SyncML.

  5. Real Cloud on Ask Slashdot: Building a Personal FOSS Cloud? · · Score: 3, Informative

    I did misread this. When I think cloud computing, I am coming for a CS point of view, which is that cloud computing is the terms used to describe the efforts to make scalability of software as a service ubiquitous. Basically, the cloud is not a bunch of servers, it is the infrastructure that provides scalable services to an application layer like the web. Amazon pretty much built the best cloud and others are following their lead. So, I have been looking at OpenStack
    If anyone actually thinks this question is in any way relevant, please let me know if there are other resources.

  6. Re:Found at 125 GeV on LHC Discovers New Particle That Looks Like the Higgs Boson · · Score: 1

    The Higgs is a lot of food for thought. General Relativity shows us that the degree of gravity in spacetime depends upon the mass and its distribution. Now we can probably build a GR model that refers to the Higgs field and this would cover all matter above it. I say probably because I can't conceive of it yet - I need time and basically some really smart people to do the work for me.

  7. Re:Build your own - not at someone's house though. on Ask Slashdot: VPN Service For a Deployed US Navy Ship? · · Score: 1

    As someone who works for a foreign company in China, I can say that rolling your own under restrictive circumstances is the only real way to go, since anything that is known to provide VPN services maybe blocked. Also, I think the most important thing the OP needs to look into is WAN acceleration. Getting a VPS is one thing, but then if the link is slow or just no great quality, performance is going to suffer dramatically using regular TCP stacks, Regular VPNs alone don't solve this - you need to investigate using TCP accelerators, I have done so and despite the ongoing battle with China we do pretty well now with TCP streams that would normally be 3 to 10 times slower over such link quality.

  8. Re:Change Apache to nginx on Ask Slashdot: Experience Handling DDoS Attacks On a Mid-Tier Site? · · Score: 1

    That's too generic. I manage a heavily dynamic site and so we use both, since page caching is a waste of time, the cache has to be a little further down and the impact of using any particular brand of webserver application will be held back by the processing behind the entrance point.

  9. Re:Change Apache to nginx on Ask Slashdot: Experience Handling DDoS Attacks On a Mid-Tier Site? · · Score: 4, Informative
    Its quite normal in Slashdot for one person to rant, another rebuts everything cruelly and then another and another...

    My take on this is that nginx is cool for static pages, we all should know that.... new optimisations in Apache 2.4 hope to address some of these and Apache is easier for me to configure for dynamic sites with controllers.

    Regarding DDOS - neither of these will help... there are different types of DDOS attacks, sure. Any site that is dynamic in nature is screwed by any DDOS before it even saturates the entrance because an inability to disseminate requests in time causes the webserver to effectively stall. There are mitigations, one of the best is iptables rate limit for DOS attacks, of course defending DDOS attacks requires enough horsepower behind the scenes, so that when the entrance is saturated, requests can still be distributed usually by a load-balancer that places the bottleneck at the entrance alone - placing the site in the cloud with auto-scaling will solve this at a cost. Any type of DDOS attack that relies on an exploit though, requires a fix, removal or workaround before any horsepower mitigation can take place.

  14. Re:Design Matters on Arise SIR Jonathan Ive · · Score: 1

    I'm using KDE4 because believe it or not, to really have your nose high in the air about a quality user interface attached to a strong underlying OS you can delve into with ease, you need to be able to tie the process of building the interface to the ease of the interface and not be tied down the licencing. This is why Windows will always be virtualised into my Linux Desktop - despite WIndows 7 being the best Windows so far - many of the objects you may want to pass may not be reversibility in any form, as in text based system configuration. If you want to make it into simpler objects, nothing is stopping you. I don't want a uniform desktop designed for me, I want options, finesse, control, and usability that no consumer driven product will ever possess. As for Apple, they still need to do a lot of catch up work to be in the same usability ballpark as Linux/KDE. Maybe we just see as far as you know and we both know differently.

    There is also the assumption that each write layer is perfectly uniform despite reads being close to error. Even if there is localised uniformity in a single pass, I doubt there is any reason to assume it is purely a function of locality given manufacturers are pushing the limits of what is physically possible to make more money. If they choose to make a barely accurate reader at a given density to maximise profit, would the write process be orders of magnitude more accurate ?

    This is absolutely correct, however I think that at 256Kbps, there is a good chance most people will still not perceive a difference. I would add one step and say, if you want to know what these differences actually sound like, try different grades of MP3 in the comparison, most peoples threshold is around 160-192 Kbps - this is where they can just distinguish consciously the difference and quantify it mentally.
