  1. Yes I have. on HP Secretly Rendering Printer Cartridges Unusable? · · Score: 1

    I provided NMR as only an example. There is GC-MS, LC-MS, HNMR, C13NMR, etc.

    There are quite a few tools to reverse engineer compounds. How do you think they do it? :P

    And just because something is difficult doesn't mean there isn't software out there to predict what compounds will look like under that magnetic field. Given some educated guesses provided by generic structures and patent literature and there isn't much that can't be discovered.

  2. I never said it was anything but! on HP Secretly Rendering Printer Cartridges Unusable? · · Score: 1

    I just pointed out that a company will try to make as much money as possible. That ink design wasn't just one person- it might be 10 years of ongoing research (different generations) and different classes of compounds. I know of individuals that screened 10,000 ink compounds a year... which meant a hell of alot of purification and whatnot. You hit some winners out the door, you lose alot tho.

    As for measuring ink in Kg, heh, how do you think it's made? Dyes are recrystallized and then dissolved. Pigments are nano-milled *typically*. pure 'dyes' aren't found very often (such as food colouring) because they aren't stable.

    Look at the balance sheet all you want- if they didn't make a profit (sold their inks at cost) just how would they develop new technologies?

  3. Reverse Engineering on HP Secretly Rendering Printer Cartridges Unusable? · · Score: 3, Interesting

    It's not very hard to take an ink, purify it, dissolve it in Methylene Chloride, toss it into a powerful NMR ... and come up with a structure.

    Then quick jaunt to the patent literature will help pinpoint any patented routes that are 'protected' to produce similiar compounds.

    Finally, set up any graduate in chemistry to come up with a synthetic route.

    Retool a pharmco plant or use (*if you care about quality*) some form of purification (membrane, recrystallization, solvent exchange, chromatography) and you've got an ink with no upfront costs.

  4. If digital TVs were cheaper, I'd adopt faster. on Court Says FCC Out-of-Bounds With Digital TV · · Score: 3, Interesting

    Therefore, the FCC should convince the rest of the government to subsidize the cost of a 7000$ plasma 70" TV to about 299$. Then I'll buy it, and I won't give a rats ass (gnats-ass?) about the broadcast flag.

    Yep, I can be bought.

  5. This surprises you... how? on HP Secretly Rendering Printer Cartridges Unusable? · · Score: 5, Interesting

    Inkjet was always touted as the 'razor' for any company coming up in the ranks. The problem is ... much much much research $$ goes into finding pigments and dyes that are permanent and light fast... as well as fit the receiver requirements.

    And companies want to recoup that cost as fast as possible.

    I worked on some yellow dyes and can tell you it's a very difficult process. Very expensive- you might have 6 months of failures.. and the floor lab might be stained a million colours.

    But when it's done (and your scale up engineers have done it right) you'll get the cost of your ink way down.... I seem to remember some were down around 30$/kg. Pretty cheap. But that was the 'cost' of making the ink, not including all the $$ into research.

    And being a chemist I can tell you inks in suspension aren't good after sitting for awhile. Yes, it's in a dark cartridge, but I don't know many people that will tell you it's safe to take a drug /pill thats been in a bottle for 4 years. Ink's not a drug (tho as expensive as cipro!) but it is used to print a photograph that will, if said photo should fade, be lambasted as a "cheap ass company" for producing a bad product (See http://www.wilhelm-research.com/ ... mind you I dont have a very high opinion of his work... but it's still a consumer 'start' ... he'll be re-inventing quite a bit of knowledge because he's refused help)

    Anyways.... this shouldn't surprise anyone that works with inkjets. The high-volume people will never see the problem, only the low volume people. And those that know will probably do something like this instead http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&cate gory=1246&item=6746041397&rd=1 - note I am not endorsing this seller or product, only that I'm currently contemplating buying it...)

  7. Don't fear this, Fear Avian Bird Flu on The Cure for Cancer Might be: HIV · · Score: 2, Interesting

    This research, while initially scary, is relatively safe due to the safeguards in place.

    What you need to fear and what the general population doesn't understand is that chickens overseas are the perfect breeding ground for the next epidemic. At least one case exists where two people caught the flu bug from an infected person... who got it from a chicken.

    Can you imagine what wouldve happend had that inital carrier been infected with, say, influenza? A nice, ripe virus that mutates every year and at the drop of a hat... now being fed genes that can expand it's payload a millionfold.

    What do you think a flu vaccine would cost then? Assuming, of course, that the 20% mortality rate would be realistic...

    Anyways- this research doesn't scare me. They aren't talking about mixing different diseases yet that have radically different vectors (think Clancy). But should they try to pull this stunt with common flu, chicken pox, small pox, HIV, bird flu, and rabies... and let them stew... then we're in trouble. Byebye world population...

    Try as I might I couldn't come up with a business case to legally dispose of the material that I couldn't ebay.

    Even as it was, I was taking a risk that there was really 60% salvageable bits of equipment within each trailer. We're talking laptops refused, LCDs, etc. I figured I could get close to 90% of value, but the cost of disposing of the material was astronomical.

    That said: Dell picked up the stuff and drove it to New Jersey, backed in, and dumped it all into the pit.

    Had I known thats what they were going to do I would've followed with a U-Haul and cleaned up at the back end.

  11. I'm not begrudging them shipping- on Same Part, Same Supplier, Different Prices · · Score: 1

    I just find it annoying, thats all, and a calculated risk of doing business.

    It should be obvious to consumers that larger companies get 'breaks' on shipping. If that weren't so, do you think the tide of 'junk mail' you receive would be nearly so great? Think about it- if they were forced to pay 37 cents per letter (if that's the current cost...) instead of the bulk 17 cents or less... they'd use more targeted attacks.

    Shippings all cool and dandy. I used to buy from an ebayer that got my companies spare equipment. When they started charging 60$ for shipping and would no longer allow local pickup, I stopped.

    Ann Landers (her daughter) had that same dilemna- someone wrote in asking about urges for a child.

    She turned that person into the police.

    That person hadn't abused anyone. But recognizing a deviate behavior and 'correcting' it before irreparable harm comes to a child is more important than fixing it after the fact. (and even then, can you really fix it?)

    Have all the thoughts you want. But verbalizing them or being proud of them in a way that encourages you to act upon them... that is the actions that have crossed the line into dangerous territory. From there it is just a very small step to acting upon them.... whereas just thinking them is still a few more steps towards acting on them.

    There is no reference to her, just some scenes from a hotel. She is not visible.

    Now in 50 years who knows- maybe they'll be able to reconstruct the regions that were damaged. Doubtful due to the entropy increases in the compression and manipulation (Jpg typically destroys data rapidly on recompression after modification...)

    Plus ... not too many people resemble themselves at age 9. You'd have to know what you're looking for, similar to what teachers do in schools- posting their childhood photos and letting the kids guess who they are. Captive sampling permits this sort of 'mix and match' approach- some features that are discerned easily as an adult show only a hint as a child.

    They needed information. Rather than blur out the subject (which then becomes the focus) they repaired, to the best of their ability, the scenes and posted them.

    Frankly that's no different then sending out 'awards' to criminals and when they show up, arresting them.

    There is no 'interesting line' between privacy and law enforcement. Law Enforcementis paid to lie to GET the 'bad guy'. And anyone that says sexually assaulting a 9 year old girl (or boy) isn't bad needs to post their home address.... so that that tip can be forwarded onto the appropriate authorities (or anyone else that owns a baseball bat).

    I remember back to when I was only 2 years old- I had had surgery on ... well, we'll call it a sensitive part of the body.

    Now I don't remember the surgery, and I don't remember the antics I pulled at showing nurses why I was in the hospital... but I *do* remember the first time I had to goto the bathroom after surgery.

    That memory is so seared into my brain I can even recall I was high enough to look out a window over the cityscape, and that there was a bricked church in the background and the window had blinds (the black slatted ones) on it.

    And I remember so much so terribly much pain I don't know how I survived it.

    My parents tell me that after that brief moment of screaming I was OK... and I don't remember anything else of that event save for that moment.

    And just for comparison (of a little kid) I've had 18 kidney stones... I have a good memory for pain. But that memory makes me cringe and shiver every time I have it.

    Yup I know it's particularly anal, but I'll agree with the first post: We need more reliable drives. All of my photos are backed up 2x on DVD- one goes into a jukebox, the other goes onto a spindle, and all are stuffed into something called CDStorageMaster (fun proggy).

    The HDs mirror each other but I've not yet had time to test a catastrophic failure of this. I had a manual raid before and, when my system crashed due to a bad PSU (note: Antec replaced it free of charge) I was eventually able to get all the drives back up and running, but I was left with a very nasty taste of bad-dynamic disks in my mouth.

    So please... more storage at 35cents/gb and I'll be happy. Or 3.5 cents/gb would make me happier, but one can hope.

    Honestly- couple rounds of 0 or 00 shot, maybe even birdshot up close. Shot expands at 1 inch per yard which, if you're opponent is at 20 feet away, means he'll take a good 90% of the pellets in less than a 1 foot area.
