  1. Re:Inside the Bochs? on VirtualPC 2004 Versus VMWare 4.5? · · Score: 2, Interesting

    The problem with Bochs is not just that it is beta quality. It is useful for a subclass of things people use VmWare for, like kernel development, some debugging stuff.

    But for running windows, and windows apps under Linux on a daily basis it is not your best bet. Bochs is too slow and will probably always be too slow given the attitude I see from folks on their mailing list. They say the focus is on accuracy over usability. But their other problem is they are stuck under the weight of an implementation with a less than optimal pure emulation solution.

    If you want Free software your best bet currently is QEMU. It is definitely in its early stages but it already runs circles around Bochs since QEMU dynamically translates the code.

    And Plex86 is out of the running since they have chosen only to support running virtual Linux machines.

    Copying and use are different things. You need to understand the difference.

    Your typical slashdotter is FOR copyable, changeable software, and for licenses which allow that. Your typical slashdotter ABIDES by licenses that prevent copying and changing but allow normal use, usually by avoiding the software altogether since there are usually Free alternatives.

    Apply this line of thinking to movies: this is a license that prevents copying but also attempts to prevent normal use, that is, displaying that damn movie any way you like. Not copying or in any other way making multiple instances... but just the normal action of displaying it is somehow to be controlled.

    This is what is offensive about such overly restrictive licenses. When I buy something I expect to get some fair use rights too. But restrictive licensing, encrpytion, drm, etc have the effect of preventing you getting even normal use out of the things you buy.

    The translation I read was published by Penguin Classics I think. It had some criticism in the foreword I think that might help to understand it.

    One important fact is that "The Song of the Lord" (the Baghavad Gita) is a little sliver of the Mahabharat. The setting is Arjuna in a chariot driven by Krishna... he is faced with the prospect of going to war against many people some members of his own family. Krishna explains how even this which he does not wish to do and seems wrong can be considered Right action.

    The book had the opposite effect on me. It freed me a bit from my hard driving mindset to finish my studies and go make lots of money... I made a detour into expanding my mind with a lot of philosophy and Eastern religion stuff. Spent a little more time at the community college exploring than I probably should have. But given where my life is today I wouldn't change a thing.

    Sometimes I think the book should have a "Intellectually Dangerous" warning label on it.

    MTBF means mean time between failure, not mean writes between failure.

    If you really want to know how many times you can erase a sector of flash, that is defined. Typical consumer flash devices are rated for 100,000 erasures. However, the actual factors that go into lifetime are:

    1. How good the wear leveling algorithms are
    2. How full the flash disk is
    3. How much space you have altogether
    4. How often the processes you normally run write to the flash disk
    5. Number of erasures your flash part is rated for

    No one is going to be able to figure out what that means for them except by measuring actual use... i.e. trying it out while the disk driver is instrumented in some way.

    In general I think the best advice is:

    1. Keep a large percentage of the flash disk free
    2. Keep files that are truly temporary/intermediate files, logs, etc. in ram disk.
    3. Try it for a day and see what files are changing on the disk, and see if you can get those moved to RAM disk. Some you can't, like your working files (documents).

  14. Re:Specs on The Pragmatic Programmers Interviewed · · Score: 2, Insightful

    The mistake you make is thinking that everything that can be coded must go through a long drawn out design phase. For all code that doesn't, which I'd wager is most software that gets created on a daily basis, it is enough to know in broad strokes know what the problem is and get to work producing something that does what you want. That doesn't necessarily mean coding, but it could very well all be done by one good programmer.

    The thought that the waterfall method of hashing a spec and design out for months before any development can begin only comes from those in involved in larger projects... > 50,000 SLOCs... that are created in a herculean effort to produce a mammoth piece of software which must perform to a rigid set of specifications.

    Even in large projects, rigid adherence to waterfall method has never worked. You always wished you had spent some time prototyping (read: designing and coding) to figure out the problems you only discover after you get into implementation phase and realize there are problems with the spec.

    Good coding does require skill, that's a fact but the skill doesn't take more than 2 years to acquire, I think. Design is a more significant skill and the best programmers bring the skills of a designer to the table as well.

    The fact is that most of the time rough design and coding is done by the same person: the programmer. In such cases it rarely makes sense to spec and design then farm it out.

    If you're actually going to specify design and validate things to a degree that the only errors that are possible (a herculean feat beyond anyone's imagination) are coding errors, why bother even farming it out at that point? If the task you have created for the outsourced coder is just translating spec to code, there's barely even a task there. How many lines a day can you type when you don't have to think about it? I can code a couple of thousand lines a day if the thing is already design.

    That said I have found that corporations are on a kick that they don't want to shrink their in-house development staffs. This doesn't automatically translate to "outsource to India" which is a very big step even for large corporations. Rather they tend to rely on local software contractors.

    Now then, I can imagine someone building such a thing. Take asterix, then you need to find some PCI card which implements the same protocol as the cell phone network you are on. You need another card to connect to your analog phone line.

    Anyone know who sells cell phone pci cards, or external USB PCI cards?

    Alternatively I guess you could just rig up your cell phone to a good soundcard, and connect to control the device via the serial port. Depending on the API to the phone, you should be able to get commands to the phone to dial, detect when someone is calling and send a command to answer it.

    Not rocket science... someone must have done this already.

    Anyway, I think "space ghetto" is an extremely myopic and overly simplistic view of the show to the point of being basically wrong. Yeah when the feds first get to ds-9 it is a mess, but by the end of the first season everything is in pretty much working order, at least insofar as the NCC-1701D was ever in working order.

    And as far as the Bajorans, although the Cardassians had basically been using them as slave labor, their vibrant culture survived the occupation. So yes they had recently liberated (themselves) from the Cardassians, but though wounded as a people, being ex-slaves didn't in any way define them.

    There are reasons for choosing a dedicated firewall over a add-on software to a general purpose computer.

    Having worked for a firewall company, you are correct, there is no inherent difference between the software in a firewall that runs on your computer and one that runs on separate hardware... a so called "hardware firewall" (the correct term I would use is "dedicated firewall")

    Hardware firewall are just dedicated computers. They don't generally implement hardware state machines, or whatever. They are typically an embedded OS and TCP/IP stack with stateful packet inspection, NAT, application level gateways, etc. No sane person would try to implement that in silicon, and certainly not silicon that can be kept up-to-date. It's software, plain and simple.

    HOWEVER. You should not run your firewall on your general purpose computer.

    A dedicated firewall defaults to being "safe" out of the box, unlike your typical operating system. It doesn't have a lot of crap running on it that could be compromised. The amount of software on there is minimal (depend on that... the economics of mass producing hardware enforces that rule for you).

    Another way to think about it is: if the hacker is battling to get into your network, would you rather have him hacking away at a little box on the edge of your network that will probably trip alarms and if compromised just fail closed, or would you rather have him on your desktop hacking away directly trying to get in, where, when he defeats your desktop firewall, he's inside the gates?

The feeling I get from the show is that there is a future, the one we all understand from other Trek shows, which is in danger. The whole point of Enterprise, is, in the face of rampant attacks from time travellers on the timeline, to by and large preserve the future that we are expecting to see.
