  1. Re:There are many paths to the same flaws... on Firefox 4 Will Push Edges of Browser Definition · · Score: 2, Insightful

    Try reading his comment again. The connection between "changing the usability and UI one comes to expect from a web-browser" and XPI is exactly what has broken IE ever since Microsoft tried this (as the GP pointed out). When you blur the boundaries between a trusted environment and an untrusted environment, you break the very rudimentary security that the web-browser has. The main outcry in the comments here today is not even about the assumption that FF4.0 would be "bloated" - it's because it'll become the same insecure mess that IE is.

    A real desktop application is trusted. I installed it. I gave it access to my local drive. It is fundamentally different to some webapp running in a page that I happened to surf across.

    My browser profile is private. If it's going to "float" between browsers then how is privacy going to be guaranteed?

    Most people don't want a tightly integrated experience - because the security problems that it would cause are too much hassle for them. They want a browser that works - it browses the web (including whatever scripting, and media that requires) - but it works within a sandbox, away from the rest of their system.

  2. Re:Slicehost.com on Amazon EC2 Now More Ready for Application Hosting · · Score: 1

    As people are recommending their hosting providers this seems like a good place to ask for a suggestion. I've wanted to move my filesystem off of the machine at my place, and onto an online provider. Unlike most people looking for shell account I'm not so interested in bandwidth costs, I figure I'll only need 200GB/mon. But for storage I want about 2TB, and this seems to be the killer. Each hosting company that I've checked has built their pricing plans around the assumption that people are hosting web-apps - lots of bandwidth, not very much disk.

    What's the most cost effective way to do this? S3 looks ideal, but it is rather pricey. Dedicated hosting seems a waste as all I want is access to the storage and it's going to cost about £100/month to get 2TB of storage.

    Has anyone got any ideas / experience?

    Of course it is. Taking up too many resources on a multiuser system is a technological problem, one that is solved with disk quotas and per-user cpu utilization limits. Taking up too many resources on a network is likewise a technological problem, one that should be addressed with intelligent bandwidth accounting that allows for bursts and does not mislead users as to their permitted allotment.

    You've used the same phrase twice, but it has very different meanings in those contexts. The issue of what is too much bandwidth for a user is, as I stated, a political problem. ISPs are mis-selling their connections, and misleading their customers about how they can be used. Once the political problem of what is being sold is addressed, then it is a technological problem to enforce those limits.

    The rest of your post seems redundant. You've repeated what I suggested.

    I'm fairly sure that you have missed the point.

    We both agree about how parallelism impacts jobs in the real world. We also agree that if we can speed a job up then we don't care how it is achieved. The point that I made that you keep skipping over is that when there is no fine-grained parallelism available the key question becomes do I care about speeding up multiple copies of a job, or do I need a single job to run faster.

    The OP's choice of compilation was odd, which is what I remarked on. If I'm compiling lots of things in one project then it will go faster. But compilation itself is not easy to parallelise, and as I pointed out commercial compilers don't currently speed up single compilation units over multiple cores.

    Your false dichotomy is that a single unit must be simple (hello world) and anything more complex can be split into multiple units. Not only is this not true - but I gave a concrete example right at the beginning of where this would be a problem. This would be the point that has whistled over your head on multiple occasions.

    When the compiler needs to perform global analysis (ie if you are doing aggressive global optimisations across the whole program - not local optimisations within a single unit) there is no obvious way to speed it up. There may well be fine-grained parallelism in there but nobody has exploited it yet. There is no coarse-grain parallelism because you only have a single task - compile the whole program.

    Applying these sort of aggressive global optimisations has been the focus of the compiler community for decades. Now that multicores are becoming common it will be another interesting problem to parallelise.

    Wow, you totally missed the point of what I was saying didn't you. Fine-grained / coarse grained does matter in real life.

    If a problem doesn't exhibit fine-grained parallelism then running multiple copies is the *best* you can do. In some situations that is enough (i.e. a large project with lots of separate compilation units). In some situations it isn't enough, i.e. where you can't split your compilation into separate units because you're trying to run global optimisations across the whole lot.

  9. Re:Duh? on More Interest In Parallel Programming Outside the US? · · Score: 3, Informative

    What do you mean by "parallelize well"? Normally people would use that phrase to imply fine-grained parallelism in the problem but I suspect that you are using it differently. For example when you say that compilation parallelizes well are you talking about coarse-grain parallelism across compilation-units? This is not really a single instance of a problem being computed in parallel, but rather many independent instances of a problem. If you are willing to use many independent instances of a problem then the coarse-grain parallelism will always scale "well" - i.e linearly in the number of cores. But this does not provide a speedup in many real-world applications.

    In your compilation example, it is easy to get speedups at the compilation level using something like make -jN. But this assumes that each unit is independent. If you want to apply advanced global optimisations then this is not always the case, and then you hit the harder problem of parallelizing the compilation algorithms rather than just running multiple instances. It's not impossible but I'm not aware of any commercial compilers that do this.

    Your figures for the UK are way off.

    No, you should read more carefull. I said that 10Mb was slow for the next generation of sevices currently being unveiled - i.e. ADSL2 which is undergoing trails at various locations. I am well aware what current speeds are like as I have a 4Mb connection despite living within 0.5mile of our exchange. Although we had 8Mb at our previous address I asked for a downgrade to 2Mb because of the line dropping problems. I take it that you are aware that 10Mb is available to most urban areas through cable?

    I don't believe you that OFCOM limit contention to 40:1. Can you provide some backup? I suspect not as one of Plusnet's products is sold with a 50:1 contention ratio suggesting that you are talking out of your arse. Given that most ISPs have FUPs of around 40-50GB a month this suggests that contention to the backbone is currently 35-40:1 for most people.

    At 100:1 a connection would be fine for browsing - that is the entire point of BT products sold with a 3GB monthly cap. The only thing that would stop it being suitable (given that the bandwidth would be there) is latency. But that is a separate issue and it does not have a direct relationship with the contention ratio.

  16. Re:Not all sessions experience the same congestion on Fixing the Unfairness of TCP Congestion Control · · Score: 4, Interesting

    Even if that is true, the congestion won't be correlated between between your streams, if it occurred on the final hops (and hence different final networks). There is a more basic problem than the lack of correlation between congestion on separate streams - the ZDnet editor, and the author of the proposal have no grasp of reality.

    Here's an alternative (but equally effective) way of reducing congestion - ask p2p users to download less. Because that is what this proposal amounts to. A voluntary measure to hammer your own bandwidth for the greater good of the network will not succeed. The idea that applications should have "fair" slices of the available bandwidth is ludicrous. What is fair about squeezing email and p2p into the same bandwidth profile?

    This seems to be a highly political issue in the US. Every ISP that I've used in the UK has used the same approach - traffic shaping using QoS on the routers. Web, Email, VoIP and almost everything else are "high priority". p2p is low priority. This doesn't break p2p connections, or reset them in the way that Verizon has done. But it means that streams belonging to p2p traffic will back off more because there is a higher rate of failure. It "solves" the problem without a crappy user-applied bandaid.

    It doesn't stop the problem that people will use as much bandwidth for p2p apps as they can get away with. This is not a technological problem and there will never be a technological solution. The article has an implicit bias when it talks about users "exploiting congestion control" and "hogging network resources". Well duh! That's why they have have network connections in the first place. Why is the assumption that a good network is an empty network?

    All ISPs should be forced to sell their connections based on target utilisations. Ie here is a 10Mb/s connection, at 100:1 contention, we expect you to use 0.1Mb/s on average, or 240GB a month. If you are below that then fine, if you go above it then you get hit with per/GB charges. The final point is the numbers, 10Mb/s is slow for the next-gen connections now being sold (24Mb/s in the UK in some areas), and 100:1 is a large contention ratio. So why shouldn't someone use 240GB of traffic on that connection every month?

When the surfer decides to hunt for information on one particular domain - it is not about what the webmaster wants, it is about what all three parties want.

If a user a clicks on the ad from a competitor within a site search then guess what - the competitor looked more interesting. By censoring these ads the customer would lose out, and Google would lose out on revenue. Allowing the webmaster to restrict the set of ads shown on searches of their site would make it less black and white, but even doing this "a little" would damage the interests of the other two parties.

    These claims are from the "luddite" segment of the web - who thought that deep linking somehow breached their copyright.

Trying to drown the competition won't work anymore. Trying to support pisspoor content on 15pages with one hundred ads per page wont work, and crying that free access to the information breaks your business model won't make it change.

    Perhaps you would? You've post a link to wikipedia as an appeal to authority but you've misquoted the page and butchered your definition of NP-c. The only reason that you were modded insightful is that the average slashdotter with modpoints doesn't understand the difference.

    It's not hard to follow; if I give you a candidate solution to a problem and you can check quickly if it is true or not (i.e. in poly-time) then the problem lies in NP. So all problems in P lie within NP. Some problems in NP are harder than others i.e. 3-sat. If any single one of those problems can be reduced to the problem being discussed (in poly-time) then then it is complete within NP - it is one of the hardest problems in NP.

    The poster than you were replying to was pointing out (in terms that you didn't understand, I suggest you read his reply closely) to you that the difficulty of factoring is not related to the difficulty of NPc problems. He is entirely correct, not only is there no theoretical basis for relating the hardness of the problem but if you have spent any time working on NPc problems, and on factoring you would understand that they are very different.

    Finally, quantum computers cannot (currently) factor large integers. It is silly for you to make that claim in a discussion about whether or not QC would ever scale to large problems at all. Also the integers that they can factor are not a direct result of their non-determinism. Don't forget that we can run non-deterministic algorithms on devices other than QCs.
