Comment What's the value of an unlocked US cellphone? (Score 4, Informative) 185

Is there something I don't understand? I don't think unlocking a US cellphone has any additional value than an unlocked US cellphone. The phone's most value is on its original network and it's almost worthless on any other network.

All GSM is not equal. Unlock a T-Mobile cellphone and move it to AT&T and you get a degraded EDGE speed. And I assume that's true in reverse. An unlocked AT&T cellphone presumably has poor speed on T-Mobiles network.

All CDMA is not equal. A Verizon phone cannot necessarily be switched to Sprint -- my experience is that Sprint has to support that phone explicitly in its own network, including a possible new firmware load. And presumably vice versa.

And of course a GSM phone cannot be activated on a CDMA network or vice-versa.

So even if you can unlock your phone, there doesn't seem to be ANY interoperability with respect to carriers. Your unlocked phone has the most value on the network it came from, and almost no value on any other network.

So what's the point of unlocking it?

Please feel free to correct me and point out all the things I don't understand about cellphones. Cause I don't get it, and I assume it's due to my ignorance.

The Math of a Fly's Eye May Prove Useful 90

cunniff writes "Wired Magazine points us to recent research that demonstrates an algorithm derived from the actual biological implementation of fly vision (PLoS paper here). Quoting the paper: 'Here we present a model with multiple levels of non-linear dynamic adaptive components based directly on the known or suspected responses of neurons within the visual motion pathway of the fly brain. By testing the model under realistic high-dynamic range conditions we show that the addition of these elements makes the motion detection model robust across a large variety of images, velocities and accelerations.' The researchers claim that 'The implementation of this new algorithm could provide a very useful and robust velocity estimator for artificial navigation systems.' Additionally, the paper describes the algorithm as extremely simple, capable of being implemented on very small and power-efficient processors. Best of all, the entire paper is public and hosted via a service that allows authenticated users to give feedback."

Comment No "truly" mandatory vaccines since WW I (Score 1) 541

From Penn's Center for Bioethics:

http://www.vaccineethics.org/issue_briefs/requirements.php

Today, the term "mandate" is imprecise when applied to immunization. The last time the U.S. required vaccination without exception--a true mandate--was during World War I.1 Today, processes in place in the vast majority of states provide parents with significant latitude regarding whether to vaccinate their children.

Mandatory vaccination programs should be reserved for the most severe of disease outbreaks, and only after the designated State or Federal official has declared a state of emergency.

Comment Re:So the Pre 1.0 makes me appreciate my Treo 755p (Score 2, Insightful) 283

"Did it ever occur to you that perhaps the Pre just has a really crappy touchscreen?"

So actually I did. Next time I post at slashdot I'll write a ph.d length dissertation.

I ruled out that the Pre has a crappy touchscreen because:
  a) all of the reviewers (wsj, nytimes, and many many more) all said the touchscreen was great even in comparison to the iPhone
  b) the palms and treos had touchscreens that needed calibration and the pre somehow doesn't need calibration (and maybe it does...)
  c) palm has long been known for their touchscreens of one sort or another, hard to believe they can't do a touchscreen right.
  d) palm recently hired 200 apple engineers, hard to believe they can't do a touchscreen right

By the way, it's pretty obvious to someone who has used a palm pilot or treo and then the pre that all the pre apps were designed from day one to use a touchscreen too.

Comment The Pre PIM is Palm PIM 1995 (Score 2, Insightful) 283

Basically Palm has punted on the PIM. One complaint about the Treo and later Palms was the PIM never advanced past what it was in 1997. But on the Pre they've dumbed it down even further and gotten rid of categories and search.

So while I might keep notes or web clippings in a memo (best restaurants, best bars, all npr stations in the nearby states, lan settings for home and work, ...) now such long collections of notes are horrible to browse through or find.

It is in some sense a Google/Facebook phone, but they haven't embraced all the Google Apps yet (no google tasks, no google voice, no google reader)...

Comment So the Pre 1.0 makes me appreciate my Treo 755p (Score 5, Interesting) 283

Weird because while I love my Treo I hate my Treo, but using version 1.0 of web os makes me appreciate my Treo much more.

So yeah yeah yeah, Pre is great. But here is where I think it sucks compared to my Treo.

The calendar program is puny and worthless in comparison to the Treo + Agendus. It's very hard to visualize what is happening a month at a time on the Pre. On the Treo + Agendus, there are icons for birthday cakes, and icons for dentist appointments and all sorts of very useful 16x16 icons that help a great deal visualizing what's going on a month at a time.

The memos and tasks are truly worthless. Very hard to make detailed notes. No way to categorize or organize the notes. I have over 200 notes on the Treo and they are simple to find and all are searchable. None are searchable on the Pre and there is not even a way to categorize them.

Touchscreens are for noobs. All this time I've wondered what the iPhone crowd was crowing about with their touchscreens, but today, on the Pre, I really miss the fidelity and precision of a stylus and a 5 way navigation button the stylus lets me precisely hit exactly the point on the screen I am looking for and the nav button lets me precisely scroll up and down the number of items I desire. Exactly. Each time. Repeatedly.

The software is at a very simple and unsophisticated level. Websites constantly need to be zoomed and the browser doesn't remember that I've zoomed this website the last three times I've been to it, and so does not automatically zoom it the next time. Compare to Firefox.

And webos is slow. The whole thing feels slow compared, yes, to the PalmOS on the Treo 755p EVEN with it's white screens of death. It's frustrating and may go back to the store within the 30 day period while I wait for webos 2.0.

And I fear that contrary to what Palm has been saying, the problems will be firmware related and not an easy download. And frankly, the Treo experience is that Palm will release one new set of firmware, maybe two, and then consider the phone dead and push people to get the next one.

So we'll see. I think the hope of the phone is:
  * a firmware upgrade from palm
  * release of mojo sdk and native apps from long time palm developers

Ya know, just because the iPhone only has one button doesn't mean Apple was right to go that route. Apple loved their one button mouse for a decade when everyone else knew how stupid that was. 5 way nav buttons and a stylus isn't such a horrible klugey interface as much as forcing touchscreen for everything is.

Comment Re:False sense of security (Score 1) 461

Everyone is ragging on the OP for cites and saying it can't be true because it would break laws. (As if that means much these days....)

It's Time to Drop the 'Expectation of Privacy' Test
Commentary by Bruce Schneier

In the United States, the concept of "expectation of privacy" matters because it's the constitutional test, based on the Fourth Amendment, that governs when and how the government can invade your privacy.

Based on the 1967 Katz v. United States Supreme Court decision, this test actually has two parts. First, the government's action can't contravene an individual's subjective expectation of privacy; and second, that expectation of privacy must be one that society in general recognizes as reasonable. That second part isn't based on anything like polling data; it is more of a normative idea of what level of privacy people should be allowed to expect, given the competing importance of personal privacy on one hand and the government's interest in public safety on the other.

The problem is, in today's information society, that definition test will rapidly leave us with no privacy at all.

In Katz, the Court ruled that the police could not eavesdrop on a phone call without a warrant: Katz expected his phone conversations to be private and this expectation resulted from a reasonable balance between personal privacy and societal security. Given NSA's large-scale warrantless eavesdropping, and the previous administration's continual insistence that it was necessary to keep America safe from terrorism, is it still reasonable to expect that our phone conversations are private?

Between the NSA's massive internet eavesdropping program and Gmail's content-dependent advertising, does anyone actually expect their e-mail to be private? Between calls for ISPs to retain user data and companies serving content-dependent web ads, does anyone expect their web browsing to be private? Between the various computer-infecting malware, and world governments increasingly demanding to see laptop data at borders, hard drives are barely private. I certainly don't believe that my SMSes, any of my telephone data, or anything I say on LiveJournal or Facebook -- regardless of the privacy settings -- is private.

Aerial surveillance, data mining, automatic face recognition, terahertz radar that can "see" through walls, wholesale surveillance, brain scans, RFID, "life recorders" that save everything: Even if society still has some small expectation of digital privacy, that will change as these and other technologies become ubiquitous. In short, the problem with a normative expectation of privacy is that it changes with perceived threats, technology and large-scale abuses.

Clearly, something has to change if we are to be left with any privacy at all...

Comment You sell it as service, but it's much more.... (Score 1) 729

You raise an interesting point, and I think there is a bit of truth that this may incentivise bad behavior.

But done right, and your service is much more than bug fixing. It's market research as you interact with customers and find out there current problem and their future needs. It's customer maintenance since each time you interact with your customer you are selling them again on why your company is the smartest, friendliest, easiest to work with, thus keeping them from buying competing products. It's customer tutorials as you explain how to setup the normal installation, and how to use, and why and when to use advanced features the customer isn't even aware of.

All of this can be used to help your customer understand the value that your company's support provides.

(Caveat: I just pulled this response out of my butt. I think it's truthy good, but ymmv.)

Computer Error Caused Qantas Jet Mishap 389

highways sends word that preliminary investigations into a Qantas Airbus A330 mishap where 51 passengers were injured has concluded that it was due to the Air Data Inertial Reference System feeding incorrect information into the flight control system — not interference from passenger electronics, as Qantas had initially claimed. Quoting from the ABC report: "Authorities have blamed a faulty onboard computer system for last week's mid-flight incident on a Qantas flight to Perth. The Australian Transport Safety Bureau said incorrect information from the faulty computer triggered a series of alarms and then prompted the Airbus A330's flight control computers to put the jet into a 197-meter nosedive ... The plane was cruising at 37,000 feet when a fault in the air data inertial reference system caused the autopilot to disconnect. But even with the autopilot off, the plane's flight control computers still command key controls in order to protect the jet from dangerous conditions, such as stalling, the ATSB said."

Submission + - Paul Krugman 1978: TheTheory of Interstellar Trade (nytimes.com)

jerryasher writes: Paul Krugman, writes at his New York Times blog about his early papers: Thirty years ago I was an oppressed assistant professor, caught up in the academic rat race. To cheer myself up I wrote — well, see for yourself. Joshua Gans of the University of Melbourne scanned a copy of the thing I wrote — back then academics did their work with typewriters, abacuses, and stone axes — and was good enough to send me a copy. Ladies and gentlemen, I give you The Theory of Interstellar Trade. Abstract: This paper extends interplanetary trade theory to an interstellar setting. It is chiefly concerned with the following question: how should interest rates on goods in transit be computed when the goods travel at close to the speed of light? This is a problem because the time taken in transit will appear less to an observer traveling with the goods than to a stationary observer. A solution is derived from economic theory, and two useless but true theorems are proved.

Does anyone know of spell checkers for programming languages? I don't want a text spell checker, I want a programming language aware spell checker. A spell checker that I can pass all of my code through and will flag spelling errors in function names, variable names, and comments, but will ignore language keywords, language constructs and expressions, and various programming styles (camel code, or underscores, or ...) I want a spell checker that knows that void *functionSigniture(char *myRoutine) contains one spelling error. Does anyone have such a thing for Java or C++? Are there any eclipse plugins that do this?
