April 1, 2006, San Francisco, CA: In a surprise move, Department of Justice (DoJ) attorneys filed a subpoena yesterday in federal court against the National Security Agency, requesting one million sample Google searches. They plan to use the searches as evidence in their defence of the constitutionality of the Child Online Protection Act.
Next week (Mon-Tuesday) I will be speaking at David Isenberg's "Freedom To Connect" conference, on an open net, in Silver Spring, Maryland (Washington DC.)
April 10 I will be at UCSB's CITS conference (Santa Barbara, obviously) on growing network communities.
The next week April 19-21 sees the annual Asilomar Microcomputer Workshop, always a good time.
See you there.
Today many services offer MRI scans for a fee. DNA testing services are getting better and better -- soon they will be able to predict how likely it is you will get all sorts of diseases. Many worry that this will alter the landscape of insurance, either because insurance companies will demand testing, or demand you tell them what you learn from testing.
Jeff Pulver is a giant fan of the SlingBox, a small box you hook up to your TV devices and ethernet, so you can access your home TV from anywhere. It includes a hardware encoder, infrared controllers to control your cable box, Tivo or DVD player, and software for Windows to watch the stream. The creators decided to build it when they found they couldn't watch their San Francisco Giants games while on business trips.
And I get that part. For those who spend a great deal of time on the road, the hotel TV systems are pretty sucky. They only have a few channels (and rarely Comedy Central, which has the only show I both watch on a daily basis and which needs to be watched sooner rather than later) as well as overpriced movies. But at the same time you have to be spending a lot of time on the road to want this. My travel itineraries are intense enough that watching TV is the last thing I want to do on them.
But at the same time it's hard not to be reminded of the kludge this is, especially hooked to a Tivo. And if you have a Tivo or simliar device, you know it's the only way you will watch TV, live TV is just too frustrating. I don't have Tivo any more, I have MythTV. MythTV is open, which is to say it stores the recorded shows on disk in files like any other files. If I wanted to watch them somewhere else, I could just copy or stream them easily from the MythTV box, and that would be a far better experience than decoding them to video, re-encoding them with the SlingBox and sending them out. Because of bandwith limits, you can't easily do this unless you were to insert a real-time transcoder to cut the bandwidth down, ideally one that adapts to bandwidth as the Slingbox does. And I don't think anybody has written one of these, because I suspect the MythTV developers are not that too-much-time-on-the-road SlingBox customer.
(Admittedly the hardware transcode would be useful, but a 3GHZ class machine should be capable of doing it in software, and really, this should just be software.) For watching live TV, if you cared, you probably could do that in Myth TV. If you cared.
So the SlingBox...
Two thoughts today related to global warming.
Many people fear that as the developing world starts developing more, it's going to want more fossil fuels, and will burn them like crazy and add more CO2 to the air. China is the country feared the most. As you can see in my many pictures from there they burn a lot of coal there and the air is most often hazy from it.
As I've written before, Google's Adsense program is for many people bringing about the dream of having a profitable web publication. I have a link on the right of the blog for those who want to try it. I've been particularly impressed with the CPMs this blog earns, which can be as much as $15. The blog has about 1000 pageviews/day (I don't post every day) and doesn't make enough to be a big difference, but a not impossible 20-fold increase could provide a living wage for blogging.
I've done a few threads on eBay feedback, today I want to discuss ways to fix the eBay shipping scam. In this scam, a significant proporation of eBay sellers are listing items low, sometimes below cost, and charging shipping fees far above cost. It's not uncommon to see an item with a $1 cost and $30 in shipping rather than fairer numbers. The most eBay has done about it is allow the display of the shipping fees when you do a search, so you can spot these listings.
For some time in my talks on CALEA and VoIP I've pointed out that because the U.S. government is mandating a wiretap backdoor into all telephony equipment, the vendors putting in these backdoors to sell to the U.S. market, and then selling the same backdoors all over the world. Even if you trust the USGov not to run around randomly wiretapping people without warrants, since that would never happen, there are a lot of governments and phone companies in other countries who can't be trusted but whom we're enabling.
New York, March 22, 2006 (CW) Bell South and AT&T, two of the remaining Baby Bell or "iLec" companies announced today, in conjunction with GoodPackets Inc., a program to charge senders for certified delivery of internet packets to their ISP customers.
William Smith, CTO of Bell South, together with AT&T CEO Ed Whitacre, who will be his new boss once the proposed merger is completed, made a joint announcement of the program together with Dick Greengrass, CEO of GoodPackets.
Very technical post here. Among the children of Unix (Linux/BSDs/MacOS) there is a convention that for a program to open a TCP or UDP port from 0 to 1023, it must have superuser permission. The idea is that these ports are privileged, and you don't want just any random program taking control of such a port and pretending to be (or blocking out) a system service like Email or DNS or the web.
This makes sense, but the result is that all programs that provide such services have to start their lives as the all-powerful superuser, which is a security threat of its own. Many programs get superuser powers just so they can open their network port and, and then discard the powers. This is not good security design.
While capability-based-security (where the dispatcher that runs programs gives them capability handles for all the activities they need to do) would be much better, that's not an option here yet.
I propose a simple ability to "chown" ports (ie. give ownership and control like a file) to specific Unix users or groups. For example, if there is a "named" user that manages the DNS name daemon, give ownership of the DNS port (53) to that user. Then a program running as that user could open that port, and nobody else except root (superuser) could do so. You could also open some ports to any user, if you wanted.
