    Sine Nomine isn't a terrible consulting company, either.

    I worked for a company that used their services to help us design and implement a fairly major project. They had one guy come to us onsite and another guy help him out with the planning. Their solution wasn't the flashiest. It wasn't the newest tech. It probably wasn't the absolute fastest, and certainly wasn't the most vertically scalable. It scaled really well horizontally, though, and was really reliable.

    Despite a higher hourly rate and higher travel expenses than some, their quote was on the low side over all. They knew enough to get the job done in a reasonable manner in a short period of time.

    Based on my past experience with them, I'd probably trust them for support on any fork they released. It's always nice when the code goes back to the core project and others are willing to support it, too. Sine Nomine is probably a good choice if you can afford them, though, since they did the work on the port.

    This could be useful for flooded areas, too.

    You assume I'm talking about an existing rod fission reactor. I am talking about high-temperature fusion reactors. Take a look at the Sun. High temperatures are guaranteed from high-temperature hydrogen fusion. Hence the name.

    The heating of some water to steam, even 850 degree steam, wouldn't impact the heat of a 10**9 kelvins very damn much. Getting the water close enough to take advantage of the heat might be an issue. There are significant barriers to the high-temperature fusion plants themselves, too, but there is progress in that area.

    Batteries might be a better carrier someday than hydrogen or hydrocarbons. Lithium-ion is probably not the technology to do that. Zinc-silver might be if ZPower actually solved the dendrite issue with them. Ultracapacitors would be nice, too.

    Coal, oil, and natural gas are inherently lossy, too, or did you think we're currently producing new dinosaurs and forests and fossilizing them faster than they're being used?

    Using anything as an "energy carrier" doesn't mean you're violating the second law of thermodynamics. As far as anyone knows, there's no way at all to ever do so. The whole idea of an energy carrier, even one like gasoline or diesel, is that it produces more energy on site than it takes to deliver it. It does not produce more energy at its final destination than what it took to produce in the first place.

    Well, if speed is that much of a factor then you want your memory fabbed at a smaller node anyway, right?

    The RAS recharge and data cell recharge in modern RAM is handled by the memory module anyway. The CPU just tells the module when to do it. So the module should be able to separate that from the read/write voltage on the data and address lines if it's dealing with two very different voltage ranges. The right solution, though, is to put the RAM through a die shrink.

  16. Re:About overclockers: on Overclocked Memory Breaks Core i7 CPUs · · Score: 1

    What about inline solid resistors?

    The higher voltage is used almost entirely to shorten the RAS recharge time, IIRC. The data line voltage usually shouldn't need to be the same as the refresh voltage. If your memory really requires 2 volts these days to send data to and from the processor, then you need a process shrink.

    Memory can only be read or written at the proper edges of the clock frequency, so allow a write then refresh before the next possible read. The higher refresh voltage takes care of refreshing quickly and accounts for the voltage leak. The lower data line voltage to the processor means no damage.

    This all depends on something other than the on-CPU memory controller providing the higher voltage for the refresh rewrite only, under the control of the memory controller.

    In a CAS-before-RAS memory implementation, the memory controller sends CAS then RAS and the memory module refreshes itself. There's no reason the actual refresh voltage would need to flow through the memory controller. If there's no separation of the RAS recharge voltage from the external data lines, then that's a limitation of the module design. The modules would, again, be in need of a process shrink so they don't need so much voltage or a design change so that the higher voltage for internal module requirements don't flow out to other components.

  17. Re:About overclockers: on Overclocked Memory Breaks Core i7 CPUs · · Score: 1

    The main power issue with RAM is the refresh pulse being high enough voltage so that it happens so frequently with enough reliability. There's not much reason with the nature of DRAM that the read and write voltages need to be as high as the refresh voltage.

    You could accomplish this, if the memory can be read and written with a lower voltage than the refresh pulse, by putting resistors inline on the bus.

    Unix and Windows are different mindsets as much as different technologies. Perl fits the Unix mindset very well. That said, although I am both a Perl programmer and a Unix user, I'd rather have Perl on my Windows machine than mess with VB, ASP, or C#.

C# would be the way to get Windows-specific code that kinda sorta works on Linux with Mono for more serious projects.

    Look up "Moose". It's a module for objects in Perl 5 that pretty closely match the default implementation of objects in Perl 6.

    Larry has promised that Perl 6 will still have most of the flexibility of Perl 5, but the design is going to include good defaults throughout the language rather than forcing you to always roll your own.

    If you have a real hard-on for OOP, then you will probably love Perl 6 some day when it's out. Even the parser is just polymorphic methods, and therefore you can extend it and override parts of it at will. There's even enough thought behind the mutability and overriding of the parser that there are no reserved words and no numeric precedence levels. If you want a certain level of precedence, you say which operator you want the same precedence as, or that you want higher or lower precedence than operator X. You can whole new precedence level in between multiplication and addition, if you really need it, and all in one statement.

    Well, Microsoft has been one of the big fund sources for ActiveState's ActivePerl package.

    One thing you must realize about Perl before you go and stick it on the CLR is that Perl is severely dynamic at several levels. The CLR is a stack-based virtual machine for languages that are slightly dynamic. It really isn't a very good fit. Perl 5's parsing rules also happen to be very complex.

    That's why Parrot was invented -- it's a register machine VM with automatic spilling and designed from the ground up to work well with highly dynamic languages. It's also designed to allow multiple languages to be compiled down to byte code for it. The main language in question is Perl 6. Perl 5, Ruby, Python, and PHP interpreters are also being written for it among others.

    There have been many minor to major improvements in Perl 5 since 8 years ago. Among them are a mostly iterative regular expression engine, better threading, a native case statement (called given) and a new popular object system (as a module) that most people who try it like more than the original stock Perl 5 objects. Most of the serious heavy lifting in Perl implementation is being done on Perl 6, though. Rakudo (the implementation of Perl 6 on Parrot) is progressing and Parrot itself is stable enough that people are starting to write directly to it for production use.

    If the people who develop perl think that Perl needs a different kind of VM to run its best and they've spent eight years on the language and VM, then why disregard all that now that completion of that work is within sight? Why shoehorn Perl 5 into an environment where it won't fit when there are viable systems for running it and it's about to be largely superseded?
