  1. Re:problems with oil cooling on Oil-Cooling 802.11 Infrastructure · · Score: 1

    Nope, that is not the biggest problem. The biggest problem is that oil, diesel fuel, etc are so bloody higroscopic. Anyone who have tried to mix ammonal using what is written in the popular books (not the real ones) and had it refuse to explode will tell you that.

    In order to keep oil dry you need a boatload of something like Calcium Stearate and a fully closed system. If it comes with contact with air anywhere it will go to 5-15% water in no time at all and become conductive. And then - boing...

    That is the serious difference between control on the SPAM level and trader level. ASA involvement can be on the trader level. This means that they may directly force the trader (if a UK) company to restrain from SPAM practices and they may also issue such a decision.

    It is true that their decisions do not have the force of a legal act. But AFAIK there have been practically no cases in recent UK history for a company to try to disobey them.

    IMO you need a clue bat application.

    1. As far as I know, Sun tried to license NFS. Failed. For various reasons. Do not try to pull that "give to the community crap" at least as far as NFS is concerned.

    2. Solaris (not SunOS) NFS support until 2.6 was crap. Many patchlevels even as late as 2.5.1 had quite a few data corruptions bugs. As a result most old non-academic installations actually used NetAppliance when they needed NFS.

    3. I had to be a design authotity on something like 100+ Netra T1s with Solaris running the most elementary services like DNS, news, mail, etc. None of them running more then one service so they were not even loaded. And frankly I have not seen so many hardware failures and memory leaks in the core OS anytime before and anytime after. Basically white boxes from a bandit corner shop have lower failure rate and most linux kernels in the 2.3.x and 2.5.x series were more reliable.

    4. If you have created a website that needs one 100+ CPUs box instead of having the load spread across several redundant systems you should be fired on the spot. Frankly, have you ever heard of single point of failure? Actually, have you heard of dot.bomb? There were some sites like "The Street" which tried this technological model. All of them failed and dragged several decent ISPs which decided to cater for this model with them.

There is a gas station every 10 km on major roads and every petrol station sells gas. Even Shell surrendered to the laws of economics and started selling natural gas.

From there on actual fingerprinting will require knowlegde of the exact P2P protocol but even looking for simple strings can give more then enough information.

    RC4 has a history of implementation flaws. It is a good algorithm but it is quite often applied to the wrong problem and IMO anything that is not classic stream and has known plaintext fragments is a "wrong problem". The results of such misapplications are well knonw. MSFT 40 bit PPTP, WEP are just a few fine examples.

    So for this specific case I would personally run away from RC4 like hell.

    Also, in order to do this attack the attacker has to a be a man in the middle with capability to intercept and replace traffic. Outside the scope of a university campus network the possibility for such attack is becoming a very rare occurance as most networks do not have a suitable point to do this without exposing yourself.

    Absolutely agree (as a network admin).

    I will also add to this:

    • BSA, RIAA, MPAA and other A(sses) recently got into the habit to collect IPs from various P2P networks for further persecution so any "slacker" at work may bring you a BSA audit. Even, if your software is 100% legal, the time waste to fish out all licenses, proofs of purchase and prove that we are OK will cost any business a considerable amount of money.
    • Besides the BSA, RIAA, MPAA there is also the Script Kidd0tz A. Which also collects IPs from P2P services. Every time someone tries to run such shit at work (and invariably be caught) I notice an increase of 20-30% in the number of port scans we get.
    • And on top of all is the level of infestation of P2P networks with Troyans and other such shit.

    So overall, anyone caught with P2P on the networks I run is offered an offer of either donating to GreenPeace, planting a tree for every attempted donwload or being referred to the boss for disciplinary measures.

    The funniest bit here is that I QoS down all P2P shit to 32Kbit total for everyone with a 5% random drop. And everyone knows it. And there are still people trying from time to time (people apparently never ever learn).

    IBM, Dec, SGI, Sun (w)are all small companies? Nice to hear that...

    Hmm... Check their results over the last 30 years. They have not made a single penny out of OS licenses. In all cases development costs outweighted the OS license revenue by a margin of several times (excluding IBM suicidal abandoned licensing experiment with AiX 4.0). And in all cases the financial results in the OS divisions (and for many apps as well) came from support.

    Sorry pal. You have no clue. At least as far as Operating System economic model is concerned. Compilers, infrastructure software, etc generally also fall into the same category. They have always lived out of support revenue and will continue to live out of it. Ever heard of IBM global services?

    This does not mean that various other ecnomic models are not better for end-user apps, high end specialized software, etc. But that is an entirely different matter.

  21. Re:Russians Can Help, But Can't Sustain ISS Alone on The Search for Secret Shuttle Parts · · Score: 2, Insightful
    What have you been smoking? I want some ya know...

    And, of course, remember that tthe station is not yet complete. Only the Shuttle can do that job.

    What a load of bullshit. About half of it in terms of weight happened to be where it is on the back of a Proton booster. Which russians have been and are launching with a frequency of a flight per month or more to carry commercial satellite payloads. So no problem there whatsoever and actually the Shuttle is the most inefficient and expensive way to continue the expansion of the ISS.

    Using the Russian craft effectively limits the station's capabilities. Since the Soyuz is the only way to get the crew off the station in an emergency, that means no more than 3 people can be onboard, which is about one-half the intended crew complement, I believe.

    The ISS AFAIK has more then 6 docking ports. While you can dock at most two shuttles to it due to space constraints, you can make a Christmas tree of Soyuz and Progress craft out of it. Which in fact means more crew then with a shuttle.

    The cargo-capacity of Progress, only a small fraction of the Shuttle's, is simply insufficient to resupply the station in the long term.

    After you do a bang for the buck calculation you suddenly find out that Progress is actually a more efficient means of delivering payload. It is less then the shuttle at a time but it is more the enough as Salut and Mir has proved through the years.

    Overall, using shuttle for the ISS is only a matter of politics. What the ISS needs to make itself ecomomically more reasonable is not more shuttle. It is a higher capacity cargo container launched with disposable boosters like the Ariana 5, Proton or if it is something even bigger Energia. After all that is what Energia was designed for - to be a modular booster capable to deliver hundreds of tons into low orbit (it cannot reach stationary).
