Been doing that since we installed exchange years ago. We use the sendmail machines to queue mail when exchange is upset. Then we used it for spamassassin tagging. More recently we are using it with bogofilter tagging. Surprisingly, using a badlist trained my personal spam stream, 400/day, and a goodlist from my mail, plus a few percent of other people's mail we get a 99.8% spam kill rate with virtual zero false positives on everyone's email. (We don't actually kill the mail, just add a header and let people's mail agents dispose of it however they wish. We encourage them to have their address books whitelisted.)
What surprises me isn't that it works, but how well it works. I wonder why spam even exists at this point. It turned out to be trivial to virtually eliminate it, I wonder why everyone doesn't.
I know, its too late, no one will ever read this but...
I run memtest86 whenever i suspect a problem. Sometimes it has to run through warm up for the problem to trip. I had machines that took as long as 8 hours of memtest86 before they generated errors.
So, add $5 to the cost of a new machine for a robust memory system, or set up each new machine and bench test it for 8 hours, then whenever it crashes mysteriously bench test it again?
The market consistently chooses not to spend the $5 on robust memory systems in their new hardware. Its the pocketbook vote that matters.
Just something to think about, the gist being we will not have reliable computers until we demand them...
Your guy had a computer that crashed twice a day from bad ram. Why doesn't he have parity ram and some mechanism for the computer to hollar "hey, i got a parity error, my ram is bad"? SIMMs come in 64 bit chunks these days.
Parity will cost 2% or so. ECC adds 10% on 64bit ram. Why not? You've got a component that is probably the 2nd mostly likely cause of failure (power supplys being number 1, fan failure), is probably the most expensive failure to diagnose becuase of its random nature, and for a $5/computer cost (typical) you could identify and eliminate it.
Why don't people demand this? Why didn't you demand this on your workstation?
I know I've personally wasted more than 40 hours of my life debugging systems that turned out to be bad RAM in the end. $5/box RAM insurance is pretty cheap in those terms.
Video Editting and HD streams - The answer is in there... streams. video by its very nature is perfectly suited to being streamed. HDTV quality DV is 50Mbit/sec (I think), 2.5 minutes/gig. Unless your programmer is an idiot (and granted, lots are) you don't need to hold your whole scene in ram simultaneously. Effects only need the surrounding couple of frames. Non-linear jumps are a quick disk seek, easily fits in the vast surplus of disk speed. Sure you are working with lots of data, but it can come and go from your hard drive very nicely.
Visualization - depending on the dataset and processing, this can actually be one of the 6 programs that can use 64 bits. 'slicing' an N-dimensional dataset down to 2d is a good example. Huge pool of data, very little processing required on each sample.
Yes. It is nice to use a 64bit integer for time when the semantics require integer math. But what percent of a web browser's time do you really think is consumed doing javascript time math? 0.001% would be a good guess, but i suspect probably several orders of magnitude too high. Speeding up time math by a factor of 6 (my high end guess at the improvement for a 64bit opcode versus the pair of 32bit opcodes) isn't going to be measurable.
64 bits is mostly silly for 99% of applications. Sure its nice to have wider data paths, but that doesn't require any code changes. And sure, as with any radically different procressor implementation the code generator optimization rules need to be changed in the compiler...
But the 6 applications that could actually benefit from a process address space greater than 4GB, or were simulating 64 bit integer math are the only ones that need to be recoded. (Lets see, oracle server comes to mind, nothing like caching the whole database for performance. We do that regularly when possible. Is it on os-x yet? I'm not sure anything else comes to mind. I suppose the computational fluid dynamics folks and other simulations might appreciate it. In general it is the people who do a little bit of processing to large amount of data on a repetitive basis that benefit most from larger address spaces.)
Still, don't underestimate the importance of that code generator rework I mentioned before. I would presume that the applications benchmarked are the regular old 'optimized for motorola g4' versions and a recompile with the new code generator will result in 5-25% improvements. (You might wipe that number off before you use it anyplace else. It came out of my ass.)
Now thats just silly. Correct arithmetic does not make correct conclusion. Oh wait, I just checked in preview, your arithmetic is wrong. PI*r*r... 3.141596*50*50 = 7853sqkm... ~9kbps/sqkm. Maybe you used PI*PI*r*r? Anyway, to continue...
Just like cellular phone cell size, you tailor the coverage area to match the number of subscribers. In an urban area you use small cells, as small as a block or 4, in rural areas crank it up and cover a whole county. (I'm from Missouri, ours fit. Nevadans and Austrailians not so.)
Not only kill firefly, but hobble it from the get go by skipping the two hour intro that sets the stage. Note to studio execs... (I'm sorry, I can't resist the format...I am weak...)
The buildings that remain from 400 years ago only do so by dumb luck. Virtually all of their contemporaries have failed, even ones of similar design and construction.
To last 400 years a structure needs to be built of non-degrading materials, with a design that remains useful despite unknown domestic evolution, in a location that remains desirable, but not so desirable that the house is removed for redevelopment of the property, and in a style which will always be at least acceptable. Only one of those criteria is under the designer's control.
Simply seeing 400 year old houses no more implies the ability to create them than seeing someone win at roulette implies you can pick the next winning number.
This article is about a guy that used a punitive damage law to punish a spammer. Hardly and eye-for-an-eye. That would be spamming a spammer. See a slashdot article from a couple of months ago for that.
Studio costs are just one part of production for a typical album. They also usually include a producer to guide the project (assuming you want to be a commercial success) and paying the band an amount to live off of during the process.
Choruses also usually spend less time in the studio than the typical band. The chorus is working from a precomposed score and can sing their parts right the first time. Overdubbing, multiple takes, mistakes, and experimentation all take time.
Manufacturing/distro is in the $2/cd neighborhood. Marketing can be huge.
I upgrade every 4 years, but that is not quite true. Since I have a desktop and a laptop, a wife and kids it goes roughly like this... Even year: upgrade my iMac, give old one to kids, give old kids iMac to my brother Odd year: upgrade my iBook, give old one to wife, give her old laptop to my mother.
So each computer does 4 years service in my house but it migrates from my more demanding uses (development, multitrack audio recording) to the less demanding users.
What you need to do to ensure timely hardware upgrades is a bunch of dependents that don't need the fastest computers.:-)
(And no, the 17" doesn't mean I can dispense with my laptop. I value "small" for many of my laptop uses. An iBook AND an iMac cost about the same as a 17" powerbook. Still, I'd like a superdrive in the portable...)
First, I think the 217kbps is referring to encoded data. you don't have to do async encoding on top of that. Still, I distrust any claimed maximum speed. We'll see...
Second, USB does have isochronous transfers for guaranteed bandwidth applications (like speakers and video cameras). I don't think 1.0 had it, maybe it crept in at 1.1? Still, at only 217kbps the wireless isn't going to do speakers or video well, not the target.
Third, short range. Yes! That is because they are low powered. Bandwidth, range, and power consumption are tied together by physics. You can play with the constants by using different modulation schemes, but ultimately more bandwidth or range is going to take more power.
You can't take my 802.11 systems away. I'm not suggesting that wireless USB or bluetooth would ever replace those. Heck, even 11mbps inspires me to walk upstairs and plug in my 100mbit wire for some operations.
Wireless USB can be a cheap addition to any computer ($10?) and allow me to get rid of my keyboard and mouse wires plus let all of my gadgets communicate with my digital hub. I look forward to having computers have "2 USB ports plus wireless USB" as a standard feature.
Yes, please do screw bluetooth. But not in favor of 802.11[abg]. The 802.11 series of protocols is much faster, but also require more power. Bluetooth uses very little power, but is speed limited.
The problem with bluetooth is that it is extrordinairily complex. needlessly complex. The standards comittee took years to create a spec so byzantine that it takes vendors years to implement.
An alternative is coming. Cypress Semiconductors is rolling out wireless USB. In a nutshell...
lower cost (simpler = less silicon; $3.50/unit. That is the wireless and the little CPU to run your keyboard, mouse, game controller, or interface to your larger device.)
lower latency (low enough for FPS games. 8ms, up to 20ms with 7 devices. Human reaction time is something like 50ms.)
higher speed (217kbps)
standard software (everything is still USB to your computer)
Their first releases are an integrated HID controller and the upstream bridge which should be available now or very soon. It isn't clear to me if the bridge chip can be used by people making non-HID hardware devices, like PDAs, as a client interface.
You can read their old press release here. There is a link to a nice PDF at the bottom of that page.
Leading unanswered questions...
How does it get along with 802.11[bg]? They are in the same band, both frequency hop.
Cell phone companies do not move quickly. Will they consider a cheaper alternative to bluetooth?
Is the product on track? Their press release is from November. There is a suspicious lack of information on the Cypress site. Their projected milestone was Q1'03, so they still have time.
Me, I hope Wireless USB catches on. I'd love to make wireless USB connected balls like these to use as system status indicators. Yes it is needlessly complex, but it compensates by being oddly cool.
Is Henry V.009 stealing gasoline? Do we have any proof that he isn't? I think we should have this before we consider his posts.
(And yes, this bit of silliness is just to remind people that accusing others of unsubstantiated wrongdoing is not a particularly persuasive strategy.)
Lindows is not obligated to provide me with source code, but the last I heard they had an online repository idenitified in their distributed media. It wasn't working quite right, but they were aware of that and fixing it.
Let's show the industry how it is done. I'm finishing a CD this month, it will be available mid February for $10. I suggest every slashdot user buys a copy, then I'll call the RIAA and tell them how well $10 CDs work.:-)
Incidentally, the $5 production cost is probably high. Even in the small volumes I work with I can get full color inserts and disc, all assembled in the jewel case, shrink wrapped, billed to a individual sale, and shipped for $4. (None of my labor! No more grueling nights assembling CDs and getting paper cuts!)
Still, I do think that slashdot users buying 50,000 copies of my disc would be a nice idea. They make nice gifts.
Its worth noting that when Atheos (nifty OS, not a unix clone, dead now) needed a browser the author evaluated KHTML and Mozilla and decided KHTML was far easier to port, then proceeded to do it in a week or so.
The crude abstract of this article implies KHTML is not cross platform. History says otherwise.
<soapbox> - you do not need to agree
Personally, I think Mozilla has set free software back about two years. Alternative browser development came to a standstill when netscape released the code. After all, we were all going to have a fast, lean, free, standards compliant browser as soon as they got it compiled. Then came the slips, the rewrites, the bloat, and the delusions of grandeur.

Positive Gs are easy utilizing centrifugal forces. Round and round to increase Gs, change the wrist angle of the robot arm to change the direction of the force relative to the person. Negative Gs are easy, just turn them 'head out'.
You won't get much in the way of sustained, reduced Gs, but you can short ones, 1 second, by flinging people downward with the arm.
They just need to make sure to put a vomit shield around the device to keep from flinging it into the spectators. I'll bet you could add an imax like projection sphere around it for a more integrated experience. Just make sure you can hose down the screens.
Sure does. From the statutes... "the right to exclude others from making, using, offering for sale, or selling"
I was going to find a better reference, but I've been seduced off topic by USC 35 section 105 wherein US patent law is extended to items invented and used in outer space if they are invented or used on a US controlled spacecraft. So you can't use this PVR legally on the ISS either.
USC 35 section 154 has the part you should read. You can get the section of law at http://www.uspto.gov/web/offices/pac/mpep/consolid ated_laws.pdf
He can only record at 15fps but is still taking 2Gbyte/hr.
He clearly isn't doing mpeg encoding. Maybe a 422 or somesuch. In any event his quality is probably far below even VHS.
He can't have a disk larger than 60G, bios trouble. (Coupled with above, he has lower capacity than even old tivos.)
He loses one edge of the picture.
It displays annoying vertical lines, but you can wiggle the card and sometimes make it clear up.
it has no user interface for selecting shows
It has no ability to look at listings. Heck, you can use your tivo this way if you want to avoid the monthly fees.
He spent $300 on hardware, yet some critical components are used gear from ebay. My DirectTV+Tivo integrated unit was less than that (just basic package too) with free dish and free installation (and that was a bitch, took the poor guy all day). Sure I pay a bit to tivo (its on the directv bill) but the total is still less than my basic cable bill was.
Don't Tivo and Replay have patents on the concept of DVR? It may even be illegal for him to overspend for shoddy substitute.
On the plus side... I have fun playing with my toys too.
Shrink your speakers down to the size of soda can.
Realize that this thing operates at a specific frequency and set of harmonics. You are free to use all sorts of resonance tricks.
You never need to get inside. You can make a metal casting 23mm thick if you wish.
I don't recall reading that his operates in the 20-20kHz range. Maybe its above 20kHz so a small amount of sound leakage is tolerable. (Seems unlikely, but... high-low separation at 20kHz is a fraction of an inch at atmospheric pressure. At higher pressure the wavelength will be greater, so that might give enough space.)
Suddenly it seems a lot easier to soundproof.
There is also the issue of the density difference from the compressed gas media in the tube to atmospheric pressure (think about sound not transferring well from water to air or back), but I suspect that is a red herring given that you are going to a more dense material first before the atmosphere.
Incidentally, I think they have a compressed gas because you can't do 173dB in free air. You rip the air down to total vacuum in the low pressure parts before you get there.
Unrelated trivia note: Your hearing ends at 20Hz. If you put a mic on your body and pitch shift the 20Hz range up into audible frequencies you will find that your body is quite loud and distracting if you can hear it.
There are already incentives in place to get many of those problems taken care of...
beverage cans carry deposits in many states. (I'm particularly fond of Manhattan etiquette that says you don't throw your can inside the street garbage can, but place it on top and the nice people come and collect them for the deposit.)
many (most?) communities have annual "nasty waste" days where they collect paint. It is mixed into giant lots of vague color and distributed to people that need free paint.
nasty waste day will also take mercury (gets recycled)
used motor oil goes back for use as fuel I believe, although I've heard that it can be purified and reused I don't think that is cost effective. We used to have a tank at our municipal recycling center for oil, but they had to take it away. It was unattended and people were disposing of hazardous waste by dumping it in the oil tank.
anitfreeze, gets recycled by businesses but doesn't pay for itself, many will allow you to drop off, sometimes for a small fee. Better than apologizing to your neighbor for poisoning their pet.
where I live there are disposal fees built in to new tire sales. Beats stock piling them indefintely in the basement.
But look at PCs. Heck, my tires last longer than cheap PCs. There isn't a financial reason to gather old PCs and dispose of them properly. They can have their life extended by being reused or having components reused, but ultimately you are dumping a bunch of lead and other minor nasties into landfill. Sure, its a foreign landfill these days, but kids still play there and drink water from the wells under it.
Simply filling your basement with old tires and disintegrating paint cans and hoping you die before you finally have to clean it up and let your executors take care of it is a pretty good microcosm of the 1970s, but for a few dollars more you can arrange to have these things properly disposed of.
I had to destroy a recording of Handel's Messiah. I handled the recording and also played in the bass section. Our orchestra scores were clear, but the choir sung from sheets that were "arranged" after the end of copy rights, 1922.
Go to the Harry Fox Agency and you will find dozens of people claiming copyright on Handel's Messiah one way or another.
It was for a small run, fund raising CD and the licensing hassles outweighed the benefits so we destroyed the recording. Still its great fun to perform it. If anyone asks you, you should accept.
Hymns have similar problems. You need to work from a pre-1922 hymnal to be clear, but you can't buy those.
I have a similar problem with traditional folk music. Everyone and their dog that ever published an album for a label with a traditional song claims ownership. I have to find documentation that the song predates 1922 to use it royalty free.

There is also the issue of the density difference from the compressed gas media in the tube to atmospheric pressure (think about sound not transferring well from water to air or back), but I suspect that is a red herring given that you are going to a more dense material first before the atmosphere.
Incidentally, I think they have a compressed gas because you can't do 173dB in free air. You rip the air down to total vacuum in the low pressure parts before you get there.
Unrelated trivia note: Your hearing ends at 20Hz. If you put a mic on your body and pitch shift the 20Hz range up into audible frequencies you will find that your body is quite loud and distracting if you can hear it.
But look at PCs. Heck, my tires last longer than cheap PCs. There isn't a financial reason to gather old PCs and dispose of them properly. They can have their life extended by being reused or having components reused, but ultimately you are dumping a bunch of lead and other minor nasties into landfill. Sure, its a foreign landfill these days, but kids still play there and drink water from the wells under it.
Simply filling your basement with old tires and disintegrating paint cans and hoping you die before you finally have to clean it up and let your executors take care of it is a pretty good microcosm of the 1970s, but for a few dollars more you can arrange to have these things properly disposed of.
I had to destroy a recording of Handel's Messiah. I handled the recording and also played in the bass section. Our orchestra scores were clear, but the choir sung from sheets that were "arranged" after the end of copy rights, 1922.
Go to the Harry Fox Agency and you will find dozens of people claiming copyright on Handel's Messiah one way or another.
It was for a small run, fund raising CD and the licensing hassles outweighed the benefits so we destroyed the recording. Still its great fun to perform it. If anyone asks you, you should accept.
Hymns have similar problems. You need to work from a pre-1922 hymnal to be clear, but you can't buy those.
I have a similar problem with traditional folk music. Everyone and their dog that ever published an album for a label with a traditional song claims ownership. I have to find documentation that the song predates 1922 to use it royalty free.
