  1. Memory is irrelevant for this kind of "processor" on New Optical Chip Claims 8 Trillion Operations/sec. · · Score: 5, Interesting

    This is NOT a Harvard architecture part - this isn't fetching instructions from RAM and executing them, like a regular DSP would.

    Think of this more like an FPGA - you have a device that is configured for a specific processing algorithm, and data is fed in at wire rate and processed at wire rate.

    An example of how a device like this might be used may be in order:
    I'm trying to find a radar pulse buried in the noise coming in from my receiver. I want to know the phase delay of the radar pulse - how long from when I sent it till I got it back.

    Now, I know what my radar pulse looks like as it goes out. I know that any reflection is going to consist of versions of that pulse shape, delayed and of varying strengths. So what I do is called a correlation - the easiest way to think of this is to imagine having 2 transparencies, one of my outgoing pulse, and one of the incoming signal. Now, I hold them up to the light, and slide the incoming signal across the reference pulse until things match up - that's the point of maximum correlation, and that give me the delay of the signal.

    A real correlation function is a bit more complicated as you have to allow for the signal level to be changed - if I am looking for a signal of N samples in a received data stream of M samples, I have to do M*N multiply and add operations to get my correlation. Now, for a radar signal I might be sampling at over a billion samples a second, and looking for a chirp of a 100 ns would give me over 100 billion MAC operations a second. There are ways to do that with conventional DSPs, but they are a galloping BITCH to do (you basically make a cluster of DSPs, and each DSP takes a part of the signal. Synchronising that is a bitch.)

    This device would work by having the shape of the outbound pulse represented in the structure of the device itself, and the MACs are done by taking the incoming data stream and projecting it on the structure - thus you do all your processing in parallel, and at wire speed. You get a pulse out when the incoming signal matched the signal you ar looking for.

  2. OMG L@MERz! U Suxor! on On Videogaming TV Shows And Vitriol · · Score: 1

    Look at the posts by the "g@merz" on Slashdot. Look at how they react to ANYTHING. "OMFG! U SUXOR! FAG!"

    This, on a board that is NOT purely a gamer board. Now, consider the effect of something that attracts only gamers - the result will be to concentrate the "g@merz" to the strength of Alien blood.

    I do not find it surprising that there is vitriol directed at a gaming channel. I find it surprising that anybody else is surprised.

    Nota Bene - I draw a clear distinction between "gamer" - "a person who plays games" and "g@merz" - "a collection of immature morons".

  3. How many tons of hydrogen on 4 Tons Of Plants per Mile to Ride In Your Car · · Score: 0

    OK, so how many tons of hydrogen had to be fused in order to make a gallon of gas - don't forget that fusion is not 100% effecient, so it takes many kilotons of hydrogen to make a ton of carbon (the rest being pissed off as heat, as helium/lithium, etc).

    Also factor in the tons of carbon that never leave the star that made it. /bullshit mode off

  4. I wonder if they fixed the bugs in Anaconda on Progeny Ports Red Hat's Anaconda To Debian · · Score: 2, Interesting

    I wonder if they fixed the bugs in Anaconda that prevent it from understanding an fstab which contains either:

    a LABEL= line instead of a device name
    a file system type of "auto"

    (and yes, I have reported both to RH.)

    Perhaps they even fixed it so that when there is a failure, you have the option of going to another VC, fixing the problem, and trying again, rather than Anaconda's current behavior of "Nope. Had an error. Gonna reboot now. Definitely gonna reboot. [OK]"

  5. I want it NOW on Google Considering IPO Auction Online · · Score: 4, Insightful

    I want it NOW

    This is not a reference to the Google stock, but rather to the pervasive attitude in today's society that is leading to our downfall as a civilization.

    I want it NOW - as in, "I am unwilling to wait, and do the sensible thing, so I will do something completely stupid to get this right now."

    Rather than waiting to earn and save enough money to buy (that plasma display|that new video card|that big SUV|...) people just charge it on the ol' credit card. Result - most of their income goes to servicing their debt.

    Companies are like this, as well. Rather than borrowing money from a bank, or folding some profits back into R&D, they look for the immediate solution - "Let's sell off part of the company!" Unfortunately, unlike a bank debt which is designed to go away after a time (when you pay it off), selling off part of the company as stock is almost impossible to reverse. True, a company can try to buy back the outstanding shares, but as they do so, the cost of the outstanding shares will rise, and they are unlikely to ever be able to buy them back.

    And I am sorry, but any employee who is swayed by stock options IS A TOTAL FSCKING MORON. The only way stock options are valuable is if the stock price of the company significantly increases from the time the options are granted to the time they are vested. As other posters have pointed out, this leads to a company trying to grow continuously, which is simply not possible. As a result, eventually you will get stock options that don't significantly appreciate in value.

    There are better ways to "incentivize" an employee (that was the very term that was used by my boss as I was offered stock options - which were so far under water when the company was bought out that I was offered one whole dollar for the lot). A profit sharing plan, in which a percentage of the company's profits are credited to an account in the employee's name, with a vesting period, is FAR MORE effective at giving a key employee a reason to stay than stock options - the employee can SEE the value, can SEE the exact amounts of money he is walking away from, and that value DOES NOT FLUCTUATE as the market varies - hence the employee is unlikely to walk away at an uptick, as upticks and downturns simply don't happen.

    Lastly, the whole purpose of playing the stock market has changed. It used to be a means by which you invested you money in a stock in return for dividends - converting cash into an annuity, thus attempting to guarantee youself an ongoing income, while still having the money available for use if needed. In that mode, the stock market is a non-zero sum game - you can gain value without somebody else losing value.

    But now, the stock market is played like a trading card game - the idea of holding a stock for years is gone, buy it today and sell it tomorrow, lather rinse repeat. When it is played like that, the stock market becomes a zero-sum game - if I make money on the market somebody else had to lose - if I bought it low from you, then you lost your chance to make money, and if I sell high to you, you are losing money to me.

    As a result, since in a zero-sum game everybody is in direct competition with everybody else with little motivation to co-operate, you get the "dog-eat-dog" mindset we see today.

    No, I hope Google does NOT IPO. Yes, it would be nice to be able to buy a few shares of a well-run company who's management is planning for the long term. However, the odds of Google remaining such a company after IPO are vanishingly small. To paraphrase Marx (Groucho, not Karl) - "I wouldn't want to own stock in a company that would sell it to me."

  6. My, how times have changed on More on the Versalaser · · Score: 1

    Back when I was working with laser marking systems (1988), they were in the $100K region for a 25 joule per pulse laser marking system. This wasn't a raster scan system - just a flash of IR through a mask, and this wasn't a cutter, just a marker.

    Now you can get a 25W continuous duty cutter for $10K.

    My, how times have changed.

    (of course, a laser capable of 15 pulses per second of 25J each, with a pulse width of 25ns, is a different beast than 25W continuous output, but...)

  14. sftp too slow - WHY? on Sending Files w/o Sending Clear Passwords? · · Score: 1

    OK, the question I would have is, exactly WHY is sftp too slow?

    The raw throughput of sftp isn't much less than ftp, given that you have enough CPU on both ends of the link for the encryption/decryption.

    You speak as though the slowdown of sftp is very large compared to ftp - not the few percent the protocol itself would add. This would lead me to beleive that you are running slow due to the encryption itself.

    So, first of all I would check the CPUs of the machines involved - unless you are running an old junque P75 you should not have a big problem filling most pipes.

    Secondly, check what encryption algorithm you are using for the link once it is up. Some of the algorithms require less CPU than others.

    It really sounds like SSH/SFTP would be the solution you want, but you just need to to a bit of tuning.
