P not equal NP

Thursday, September 2nd, 2004

This article was on slashdot today. Uninteresting little article about NP problems and how once we build our magic NP box, our current methods of encryption will be rendered useless. I particularly liked this statement: The Internet would be vulnerable to hackers and computer viruses. As though it currently isn’t vulnerable. Once we build a quantum computer or perhaps a cellular computer, it’ll be our magic NP box. No one can say when that’ll be, but I’m certain the day will come. The only interesting tidbit I garnered in that article is that Adleman is at USC.

What I don’t understand is why Garfinkel wrote the article (and spelled Adleman’s name wrong). Is this new information to him? He mentions last month’s Crypto conference, but did they have anything new to say about P vs NP problems? Probably not. And if they did, he doesn’t mention it.

And this makes me think how interesting it is to watch things go from rigorous scientific publications to mass media. How trendy some topics get. For a little while. Then you realize how long lived said topic is and the public loses interest again. Until the next cycle.

Don’t forget your RFID

Monday, August 23rd, 2004

I was reading an article in the hardcopy version of New Scientist (couldn’t find the article online to link to) about a new application of RFID — a watch that you could program with important items that you couldn’t leave the home or office without. You’d tag your keys, pager, cell phone, etc with small RFID stickers. The actual reader is too large to fit into a watch so you would have to install an RFID reader in the doorway of your house, or take advantage of RFID readers we already come in contact with out in the wild — like the card reader at work that lets you in the door. The readers would ping the tags, the watch would decode that data and buzz an alarm if you tried to leave your house without your house keys or tried to leave work without your pager.

Just imagine the wonderful uses of the forgetfulness watch — your wife could tag your wedding ring, the grocery list, your small child. Your boss could tag your laptop, the technical documents he wants you to read, the resumes you’re supposed to sift through, your pager, cellphone, and blackberry. Every time you’d tried to exit a building, your watch would go off in a beeping frenzy alerting everyone to the fact that yes, you are leaving some important piece of yourself behind. No, you cannot be trusted to take responsibility for your own things; yes, you are shirking some duty or another. You’d really be better off forgetting the damn watch.

I can’t wait to get an RFID reader. Imagine the fun things you’d find out about the people around you.

Score one for P2P

Friday, August 20th, 2004

EFF scores a win for P2P. The Ninth Circuit declares that distributors of peer-to-peer software can’t be held liable for what their users do. Don’t forget to read Fred’s comments on the ruling.

Robots in the news

Thursday, August 19th, 2004

Robotic surgery: telerobotic laparoscopic operations performed on 22 people in the last six months in Canada. Looks like Dr. Anvari, who performed the world’s first telerobotic assisted surgery about a year and a half ago in February 2003, continues his mission to prove the safety and feasibility of these procedures in the hopes of widespread adoption. It sounds like he’s succeeding at it, too.

And Seiko Epson creates the world’s lightest flying mircoboot. 12.6 grams with the battery installed — that’s less than half an ounce — and less than 1/32 of a pound. And it takes photos! It doesn’t seem to work that well yet, but it’ll get there. Here’s another article with a picture.

Implanting RFID

Tuesday, July 27th, 2004

Short little article about a pilot project in a New York hospital tagging patients with RFIDs. The RFID tag holds name, date of birth, sex and a medical record number. Doctors and staff carry around RFID readers, tablet PCs and have wifi access to the medical network. Seems like a lot of shit to be carrying around. And what about the privacy and security issues with wifi access to medical records?

The funny bit is at the end where they make mention of other RFID tagging projects including a Mexico City one where they implant people with RFIDs, just like they do with dogs and cats! And the related article about Mexicans afraid of being kidnapped getting chipped is hilarious.

Inking metallic patterns, cheaper RFID tags

Monday, June 7th, 2004

Interesting article about an ink produced by QinetiQ and Sun Chemical that allows you to draw patterns and “grow” metal. Useful, of course, for RFID tags. It’s supposed to be cheaper, faster, and more environment friendly. RFID Journal article; QinetiQ press release.

RSA security chief scientist on RFID

Wednesday, June 2nd, 2004

QA with Burt Kaliski. He makes good, rational points. He doesn’t say much that’s new in the RFID conversation, however he makes mention of something that I haven’t heard any discussion about yet — that deactivating the RFID tag also disables benefits of the tag. Currently privacy advocates believe that having the ability to disable the tag at will is a good thing. And while it may be a good thing now for privacy, I agree with Kaliski that there has to be another way to safeguard privacy and still be able to take advantage of the technology. If killing the tags is the only way to ensure my privacy, then my dreams of a smart fridge are never going to be realized.

RFID re-emerges

Saturday, May 29th, 2004

It seems like RFID news has been quiet until recently. So far there hasn’t been any talk of federal regulation of RFIDs, but now the U.S. Federal Trade Commission has scheduled a June 21st workshop to discuss RFID and the effect on consumers. Written comments about the uses of RFID will be accepted until July 9th.

I’m not a huge fan of government regulation, but think it’s a good sign that the debate about RFIDs continues to grow. Other recent news includes the RFID News “Ask the Experts” about RFID which interviews five different people from CASPIAN, HP, EPCglobal, EPIC, and Verisign. I love Katherine Albrecht’s quote (which was also posted on slashdot):

“In most cases, asking how a company exploring item-level RFID tagging can protect their customers’ privacy is like asking a fox how he can best ensure the safety of your chickens.”

Though I disagree with her that “unless they have a financial or professional stake in RFID’s success”, people aren’t going to like the technology. I think the technology is interesting and could be very useful. In the tech ubiquitous home, RFIDs would be a great addition — I think the refrigerator example exemplifies this — a computer in your refrigerator door that tells you when your milk is low and displays recipes based on the contents of your fridge. We’re quite a ways from that, and a lot of standards and policies need to be figured out in order to both safeguard privacy and allow us this convenience, but I personally would love a smart fridge.

The links off of Albrecht’s interview are a great way to introduce yourself to the reasons why we need these discussions if you aren’t already familiar with them.

On the other hand, Jack Grasso of the EPCglobal (a non-profit organization; EPC = Electronic Product Code), claims that consumers “overwhelmingly support the use of RFID for the benefits they expect to recieve from the technology”. But of course if you ask people if they want safer prescriptions or fresher produce, people are going to say yes. If they don’t understand more than that about RFID technology, they’re not fair questions to ask. And the group that did that study also just launched a joint RFID venture with Sun. They’re not unbiased. The study (which is incorporated in a pamphlet informing and encouraging businesses to better market RFID) by Capgemini (formerly Cap Gemini Ernst and Young) contains quotes like “consumer buy-in is essential given the current public debate”, “This finding indicates that many consumers have not yet formed an opinion about RFID, providing an opportunity for businesses to position RFID in a favorable light”, and “If the industry fails to educate consumers, that role will default to consumer advocacy groups”.

Cédric Laurant, of EPIC, also makes mention of the probable publicity campaign that business interests will likely undertake to make item level RFID palatable and even desirable to the average consumer. He also has a detailed list of the ways in which item level RFID tagging can be deployed in a consumer friendly manner.

File sharing still goes on

Thursday, May 27th, 2004

Who would’ve guessed: file-sharing continues unabated by the RIAA lawsuits and threats. What will they try next?

Misc news items

Thursday, May 27th, 2004

Today — I’m sure you saw it — the BBC is going to license some of their audio and video media using a Creative Commons like license. Lawrence Lessig is, of course, thrilled, and rightfully so. The BBC is awesome — for doing this and taking a progressive step in copyright, for promoting and encouraging creativity by allowing us to use their media, and also for providing excellent news coverage.

In science news, I’ve been reading a fair bit on the nanobacteria controversy — are they a new life form or just interesting crystals? It’s odd to see that a group of scientists are already marketing and selling products based on the belief that there are such things as nanobacteria before the proof has been conclusively decided. I find that extremely unscientific, but they seem to be getting away with it.

On the privacy front, some Republicans want to make the provisions that were supposed to sunset at the end of 2005, a permanent fixture of the USA PATRIOT Act — basically they expanded government rights to access and tap into personal and private information in the name of national security. Donna Wentworth has written an awesome primer on these provisions at the EFF.

On the filesharing front, there’s the wonderful PIRATE Act that turns criminal copyright infringement lawsuits into civil lawsuits so that the taxpayers foot the bill for the legal costs that the recording industry currently pays, and allows the government to wiretap to verify copyright infringement claims. Copyfight article here.

Mypod

Tuesday, May 25th, 2004

My iPod has completely changed the way I listen to music. I love music, but I’ve never been a huge consumer of it. I have a small collection of CDs and I listen to the radio a lot. Before I purchased the iPod, I would pick a CD or two and listen to it/them until I got tired of it and then would listen to another one — CDs would sit in the CD player sometimes for days, weeks.

But now that I have my entire collection on mypod, I often listen to it on shuffle. If I’m running, I listen to one of my playlists with fast, loud music on it, and if I’m in a particular mood, I listen to a particular album, but usually it’s on shuffle. At first I loved it — hearing songs I’d forgotten about or didn’t even know I had. But a few months of that and I was bored with my collection. Sometimes I purposely don’t use the iPod so that I can still be able to listen to it again.

So I’ve begun to consume a lot more music. Used CDs (because new CDs are horrendously expensive) when I’m not sure what I want and need to browse, but mostly using iTunes — where music is often cheaper than buying new CDs and you get it immediately (well, almost immediately — you still have to wait for all of it to download).

But I’ve also been thinking about how tied I am to iTunes. Which, of course, is exactly what Apple wants, right? I can’t create a new playlist without iTunes, I can’t add new music without iTunes. What good is my iPod when I don’t have my mac near me? My mac is no longer my work computer so I don’t have it with me at work on a daily basis so I’ve really begun to notice how useless the iPod is if I want to customize my music without iTunes. I could use it as a harddrive and muck with the files on there, but I can’t play any of the music that’s on there that’s not in my iTunes library without having mypod attached to a computer. Clever, those Apple folks. And selfish, too.

Not so moral after all?

Tuesday, May 11th, 2004

So, it’s all fine and dandy for me not to ’steal’ CDs and music, but the first time I want a piece of media that I can’t legally download, I go and do it anyway. I didn’t watch the superbowl and only saw the Pepsi commercial with Pink, Beyonce, and Britney somewhat recently. And I’ve been obsessed with it ever since. Last week, I searched online and got to see the video, but wasn’t able to download. So I downloaded a little tool instead, that let me capture the media stream and saved it to my hard drive.

And I’ve been thinking about it ever since. If I could buy the commercial I would — I want a quality copy of it, but no one seems to sell commercials — at least not that one anyway. And I know this question gets asked repeatedly — but where is the harm in what I am doing — I as in me, not I in a general, all of us are Is, kind of way. Having this commercial in my posession so that I can watch it every day is going to encourage me to consume. I will go and buy Pink and Britney Spears albums. I’ve got Destiny’s Child albums, but maybe I’ll go buy the Beyonce album, too. I’m easily influenced by music. I’m a huge fan of commercials — I was talking to a friend of mine about this — but I’m of the first generation to have grown up with MTV during our formative years and I’ve been hugely influenced by music videos — those short clips of amazing and interesting video and sound. My attention span is short, and if you can keep my interest before I zone out, then I’m sold on whatever it is you have to sell — clothes, music, sex, car insurance. Pair your product with some hot pop stars, and I’m a drooling mess.

I admit I’m guilty of doing something I shouldn’t have done, but I’ll make up for it.

That three minute, gladiator commercial was produced by Abbot Mead Vickers, BBDO London. Go view the commercials at bbdo.com — they’re all awesome. You can watch the Pepsi commercial here.

Robotic orange cones

Thursday, April 29th, 2004

“Herds of robotic traffic cones” might eventually be closing down lanes on a freeway near you — humans safely on the side of the road away from potential harm. These new road markers have a leader (called the shepard) who herds his little sheep into line to demarcate closed sections of road. The shepard is equipped with GPS, the human on the side of the road sits and tells the shepard where to go, the shepard watches over his little flock and goes and turns off any bad, straying sheep so it stays out of harm’s way. Isn’t that cute?

Size matters, tongues like fat, dancing robot conductor

Monday, April 5th, 2004

I hate blogging news items without commentary, but I couldn’t pass these up…

  • Size Does Matter — Mammals that live in cold climes have larger penises because they mate less often — the longer penises help deposit sperm closer to eggs and increases the chances of successful fertilization.
  • Texture matters when it comes to the foods we want to eat. Eating fat triggers pleasure zones in our brain that overlap with the pleasure zones triggered by taste. I myself am a huge fan of eating according to texture — I’m particularly fond of chewy foods — like the texture of cooked squid and really, really stale gummy bears.
  • And my favorite…robot conductor — not only can it conduct a Beethoven symphony, but it can dance, too! I love dancing robots.

Piracy doesn’t harm sales

Tuesday, March 30th, 2004

A New
Scientist article
says that downloading music doesn’t harm CD sales — in
fact, the more a song is downloaded, the better the album sells. Wow, who would’ve guessed that the RIAA might’ve been barking up the wrong tree.

Grand Challenge results

Saturday, March 13th, 2004

So it looks like as of 11 this morning the farthest anyone got was 7 miles — Red Team and SciAutonoics II both made it 7 miles along the 142 mile course. Two cars were withdrawn and the other 13 were disabled. Results here.

The Grand Challenge

Monday, March 8th, 2004

I forgot to mention this before, but Darpa’s Grand Challenge — an unmanned ground vehicle race from Los Angeles to Vegas is this weekend. The first team to finish the course within the time limit will win $1 million. There was an article about the Red Team from CMU in the March 2004 issue of Scientific American which chronicled their successes and failures over the course of several months. It looks bleak for them finishing the race in the allotted time, but it does for all the other contestants, too. However, the race will be annually repeated until someone does win or funding runs out (in 2007 I think).

The Grand Challenge main event is on March 13, 2004.

RFID forum

Friday, March 5th, 2004

The RFID forum was interesting. It was a mixed panel of librarians, privacy advocates, and a techie grad student from Berkeley. I’ve never been to a public meeting like this — the San Francisco Library Commission was there listening to the panel. No action was taken this evening, and no action has been taken so far on the RFID issue except to move forward in considering it.

They have also already put away money for this project — the first year’s funding for the RFID implementation has already been put away. It’s not in their operating budget, but if they decide to move forward with this they will move that money into their operating budget and ask for additional money.

The interesting thing for me was the human issue. I’m fascinated by this topic, but I have always looked at it from a technical and privacy issues stand point. I think, of course, about the impact it will have on people as a whole, but have never thought about individuals on a personal basis. The representatives of the libraries emphasized over and over again the costs — both financial and emotional — of the repetitive motion injuries their employees suffer. I did not write down the numbers of those affected, but it seemed a significant portion (of at least Berkeley’s) library’s funds went into workers’ compensation and / or disability. You tell could from the way the library represenatives spoke, most notably Jackie Griffin, director of the Berkeley Public Library, how emotionally committed they were to their library and the people who worked there. They are also focused on improving the services they provide and are passionate about it.

They, as librarians, are also passionate about protecting our privacy. But being involved as deeply as they are in their respective libraries, they are emotionally vested to improve their services and make work easier and less risky for their employees. It’s very easy to understand why using an RFID system would be advantageous for the SF Public Library — library staff wouldn’t have to scan every book for patrons when checking out. Patrons would check themselves out instead (actually increasing privacy by minimizing third party interaction and viewing of personal data). Managing inventory would be simpler — they claim they can just take a wand (reader) to a stack of books lying on a table and easily find books that aren’t on the shelves when other people want them.

While it all sounds great, I’m wondering how realistic it is that it will work as they think it will. One of the librarians mentioned that the wand reader worked less ideally than the vendor made it sound — tagged books had to be read at a very close distance, and had to be oriented in the same direction in order to read multiple books. What about checking out stacks of books at one time when patrons leave? I bet we’ll still have to scan the books one by one. Which is fine with me. But then, why not improve the current self check out machines? When asked about the self check out machine they currently had their complaints were that it was slow, you had to scan books one at a time, and video and other media had to be handled differently and could not be scanned. Improving those machines would free up librarians to service patrons, cut down on repetitive stress issues, and cost less than upgrading the entire system to use RFIDs.

I understand that it’s more complicated than simply upgrading and improving those machines, though — there’s still the repetitive stress from placing the anti-theft device in every single book, and the issue with shelving and finding books. But RFIDs, while innocuous now, have incredible potential to defrock us of our privacy. Cheerleaders for RFID technology say that our hypothetical concerns are unrealistic and overly paranoid, but there will easily come a time when technology is such that our concerns will not be hypothetical. And there may come a time when they are not overly paranoid either — and if that time comes, I don’t want to have in place the technologies that will make me a vulnerable citizen under an overly watchful eye.

Today’s events

Thursday, March 4th, 2004

SFGate has an article about how the SF Public library wants to put RFIDs in all its books (complete with quote and picture of Lee Tien :). There’s an RFID forum tonight at the library from 6-8 that I’ll probably attend (though the last time I said I’d be somewhere — Tuesday’s SFOBUG — I didn’t end up going).

Also — the Asian film festival starts tonight! You can finally see the Hero (Flash site) on the big screen!! It’s the opening film tonight. It’s an amazingly beautiful and tuoching film. There’s also a wonderful Korean film I think I’m going to recommend my mother see about a woman who doesn’t let her husband suck the life out of her.
