  1. Re:Good. I wondered when this would happen. on Feds to Require Digital Receivers In All New TVs? · · Score: 2

    How many millions of televisions are purchased in 10 years? Multiply that by $15 and that's the minimum amount of money that will be spent on this. Over a BILLION dollars. Perhaps a few hundred million in chips is a reasonable mandate to help the hearing impared, but a BILLION dollars is alot to mandate so that the FCC can rape the public of spectrum for cash. What do we, as consumers or whatever, need digital broadcast TV for anyway? How does anybody benifit? People who can afford this already pay for cable or sattelite, and people who can't afford cable and sattelite are going to be forced to buy new TVs, or tuner boxes. If they were going to open up that spectum for FREE public use, then I could see some value in this, but they're not going to do that.

    Sure, it was a dual processor system, and it used approx, 500 watts idle, and 600 watts at load. You could NOT use a 600va UPS, in fact, intel wouldn't let us put two systems on the same 10 amp circuit, and we had 1300va UPSs for each 2 processor system with monitor. The quads had two 20 amp power cords (the ones with the horizontal blades), and needed it's own 3000va UPS. You couldn't put two on the same UPS. That means the quad CPU systems used over 1500 watts of power at full load by your calculation (There was 16GB of memory in the systems, so it probably uses less then that in a lesser configuration). Can you say hair dryer? (BTW, the system required at least two of it's 4 800 watt power supplys to be in place to power up, so the estimation isn't that far off).

    Unfortuantly, we finished our development and sent the systems back, so I can't take any measurements to give you exact numbers. You'll have to settle for my memory of the situation.

    More has to happen then an IA-64 price drop. (Or more has to happen to cause an IA-64 price drop, depending on how you look at it.) IA-64 is a beast. It's a HUGE chip that drinks power. The system I used last used more power then any of my kitchen appliances except for the oven. That has to be fixed. The CPU with the fixin's has to cost less then just the power module probably costs right now. Then there's intel not letting anyone actually build systems with Itanium in it. They white box the systems, and let vendors rebrand them. That's not going to go over well forever. You have to wonder what intel is hiding that they won't let OEMs build boards and systems though... What dirty little secrets does Itanium hide?

    The second problem is that it's proprietary. Yes, proprietary, just like Power 4 and PA-RISC. Intel bills it as open, but if you want open you should go Sparc, MIPS, Alpha (dead soon unfortunatly), or x86. Those are the architectures that have competitive vendors manufacturing the cores. People write all kinds of software for x86. Not just desktop applications. Itanium can't get that kind of support if only Intel makes it. You'll see X86-64 in embedded devices right out of the gate. There are manufacturers DROOLING over a low power 64 bit chip to stick in their storage boxes and database servers. You won't see Itanium in there.

    You have to wonder wether there are two different companies over at intel. You've got the Pentium 4, which is basically driven by the marketing department, and is a huge marketing success, but the architecture is nothing to write home about, and generally lame in the innovation department. Then you have the Itanium, which is a big grown up microprocessor that was driven by the engineers, and is going to turn out to be a marketing failure. Oh well.

People who can't figure out how to do their job after years will never figure it out. Unfortunatly a sizeable percentage of professional programmers fall into one of those two categories because the jobs paid well, and there weren't as many good programmers as there were jobs. It's also hard to tell if somebody is a good programmer or not when you hire them. You typically can't look at their previous work like you can with somebody from almost any other profession. Also, people who can't tell and hire bad programmers, tend to hire lots of bad programmers. Anyway, back to the point: Respectful coworkers are not necissarily competent, hard-working coworkers.

    Of course for some of us that's not an issue, because the rest of the development staff on your project gets laid off and you have to write and test the whole 20k line product yourself anyway.

  9. Re:Pay no attention to the man behind the curtain on Reversing a Checksum Algorithm? · · Score: 2

    First of all, CRC is hardly encryption. Second of all, any sort of hardware you're likely to be communicating with was probably designed by somebody with a little more math background then a VB script kiddie. We're not talking about some lameo warez serial number database, we're talking about actual professionally designed RS232 hardware. Electrical engineers understand that CRC is for detecting a variety of errors, and they don't put the checksum in there for fun or obfsucation. It really is designed to catch certain errors. It's nothing complex, either. These checksums have to be computed by almost no hardware. There's usually an adder (not even a complete adder because there's no overflow bit), a single register, and a lookup table or two. If you're lucky, the table is computed in a straightforward manner using polynomial arithmetic. If not, you have no real choice but to dig the table(s) out of somewhere. We're not talking PGP here, but the table is calculated in such a way as to avoid patterns. More importantly, the algorithm should take into account not only the values of the data, but the position of each value. Maybe one device in a hundred is designed by some idiot that uses a simple checksum.

  11. Re:Itanium *IS* x86 compatible. on AMD's 64-Bit Chip · · Score: 2

    The only thing AMD has going for them (literally) is x86 compatibility.

    And price. And power consumption (better by a factor of 10!). And size. And simplicity of the bus (HyperTransport). And cost to manufacture. And third party chipset support. And working, available 64-bit windows.

    Also, from what I've heard, it runs 32 bit applications faster then existing AMD ia32 implementations. Certainly faster then a 1Ghz Pentium 3.

    If the price of Itanium stays over $1000 per processor, and it's as easy to implement SMP with hammer (Opteron... Whatever) as it looks like it's going to be, you'll be seeing 64bit AMD boxes outperforming Itanium boxes that cost twice as much. I wouldn't be surprised to see 8 way opterons for the same price as a quad Itanium.

    It's unfortunate that Itanium has such an uphill battle. It's clearly the superior architecture. Current implementations have a tough fight ahead if they can't get the complexity and the price down. At $500/CPU without the need for the gigantic per CPU power regulator and 750watt power supply, Itanium might be successful in the workstation market competing with hammer. At $1000-1500 per CPU, plus the outrageous board space and power requirements, the lack of third party board and chipset support, the insistance of intel that OEMs sell rebranded intel manufactured whiteboxes, and a host of other issues, the outlook is not good.

    First of all, don't be listening to the guys that are telling you to try a variety of input. They've obviously never done this before.

    If the sign doesn't use one of the standard polynomial CRC algorithms, you're only real option is to disassemble the binary you have to dig out the algorithm. Even if it does uses a standard algorithm (It's probably CRC16), you'll still have to figure out what data it's using. You can guess and check, and you may get lucky. Disassembling is a sure thing, and probably the quickest way to go, but check your licensing agreement.

    I recently reverse engineered the CRC for my LG TP-5250 cell phone which, as it turns out, uses the standard CRC16 algorithm, but is creative about which data is uses to compute the checksum. Without a dissassembler it would have taken months to figure out what bytes were being used and in what order. You can read about how/what I did here.
