Reverse Engineering the Nike+ FuelBand's Communications Protocol

justthinkit Re:Is anybody surprised? (69 comments)

In what way should anybody be surprised that a wearable, wireless device has implemented security in a completely incompetent way?

Right. Since Fitbit wearers are the product, to a vast array of companies wanting personal information, it sounds like the Fitbit is designed exactly how they want it designed -- to increase the value of Fitbits in the ultimate marketplace.

How Do We Know the Timeline of the Universe?

Then why is inflation the very first "unsolved problem" on this hefty Wikipedia page?

Mr. Siegel's wonderfully know-it-all blog post is based on inflation...i.e. the assumed explanation for an unsolved problem.

What are you most interested in seeing out of CES?

justthinkit Re:Something Truly Innovative (162 comments)

Money controls things, so those who focus on this will naturally be the most persistent.

But tombstones are also persistent. And landmines, Chernobyl and Fukishima. And of course Rick Astley.

So, there is more to life than just persistence.

Still, I happened to watch tonight an example of persistence from someone who is a true great in their field. Ian Anderson - Thick As A Brick, Live In Iceland. At age 67 he sounds identical to the 40-year-younger man I heard (in Stand Up) when I was a child. If he isn't the most innovative person in music, I'd like to hear some other nominations.

Back in the computing field, what about Steve Gibson? Spinrite was the greatest interface to a DOS program that I have ever seen. Especially consider how real-time and precise it had to be on the back end. Yet he is alive and well today with Shields Up, etc.

Writers Say They Feel Censored By Surveillance

justthinkit Re:"Big Brother" isn't just the government (130 comments)

When you put an overrated mod on a post, you don't have to assign a reason to what you are doing. "Overrated because I say so". It is a worse than pointless moderation. If it is a troll/flame, mark it as a troll/flame. If you just happen to not agree, you can reply but otherwise too bad for you.

My particular mod bomber(s) wait for a few days after I have posted, then fire off a couple of down mods. They figure, quite rightly, that most people have moved on, so there will be few who come along later to reverse their down-mods.

Hence my point about the need for all of us to meta-mod -- to moderate the moderators, and thus keep them honest.

Writers Say They Feel Censored By Surveillance

justthinkit Re:"Big Brother" isn't just the government (130 comments)

However, I have had someone get annoyed with me and use some kind of bot to mod down every single post that I made.

You are not alone. Shows the importance of meta-moderating... Also, Soylent is taking the route of getting rid of the overrated mod, a mod bomber favorite.

How Civilizations Can Spread Across a Galaxy

justthinkit How? (272 comments)

and fly it at 50x this speed using say fusion power

How does "fusion power" help it go 50 times faster?

Going fast is a mass problem -- you have to send a lot of mass out behind you to go really fast in space. Xenon propulsion using "just the sun" works pretty good at this sort of thing. Maybe you meant "fusion + a whole bunch of mass we can accelerate really fast and fire out our rocket butt?"

First of all, props for your comment about Monopoly above.

Amazon rates Power Grid very highly. One group, who did not care for the game, caused me to wonder what the optimum number of players is for this game. Any suggestion(s)?

Drunk Drivers in California May Get Mandated Interlock Devices

justthinkit Re:How about mandatory felony sentences instead? (420 comments)

How about make bars (& liquor stores) responsible, period.

They pay their share of all costs -- lawyers, cops, DUI-testing vehicles, repairs, jacked-up insurance premiums, death benefits, emergency room visits, funeral costs.

Businesses would quickly get out of the booze/poison business. Life would be better. Full stop.

Ditto. I have five of these, at home.

Google Unveils New Self-Driving Car Prototype

justthinkit Re:Butt Ugly (90 comments)

A good point. The Cd is just one part of the Fd. And in the Fd equation, Cd (inversely related to A) is multiplied by A so that the frontal area is removed entirely from the final equation. There should be a (Cd * A) term (although even that would not be quite right...Reynolds number being yet another factor).

It should just be Fd...

CDC caught in scientific fraud

justthinkit justthinkit writes  |  about 5 months ago

justthinkit (954982) writes "With a full headline of "CDC caught in scientific fraud, perpetrating vaccine violence against blacks in shocking eugenics cover-up", the waiting begins. The evidence is coming from a whistleblower, and will be "made public in mere days." The story continues with "MMR vaccine causes autism"...and the CDC knew it. For 12 years. So are Slashdotters still going to say vaccines are harmless? This is almost sacred ground for some."

Tattoos and why we love/hate them

justthinkit justthinkit writes  |  about a year and a half ago

justthinkit (954982) writes "For years I've pondered why people get tattoos. I've studied them, laughed at them and admired them. I've watched several tattoo reality shows and watched friends and closer get tattoos. But if I became Emperor I would ban the word "tattoo" and replace it with the word "mistake", as I think that is usually what they become, sometimes immediately. Still I'm occasionally open-minded and would love to hear other perspectives on the subject. What are your thoughts on tattoos? Do you have one or more? Are they visible? If you have tattoos, do you have piercings? How much have you spent on tattoos? Do you have any tattoos that you regret? What tattoos were painful? Do you have a favorite tattoo, on yourself or someone else? Which area of the body is the best place to have one? And the worst placement for a tattoo?"

Have they discovered a new particle?

justthinkit justthinkit writes  |  about 2 years ago

justthinkit writes "Live Science reports on the findings of researchers from Amherst College and the University of Texas at Austin that speculate there might be "a new fundamental force of nature". Having alleged long-range effects it may turn out to be electromagnetism in disguise. Still, the prospects are interesting. Thus far there are 3 possible explanations, including an "unparticle" and a Z' (pronounced "Z-prime"). Does anyone have a simple(r) explanation of the "long-range spin-spin interaction" observed?"

Best 32-bit System In 2012

justthinkit justthinkit writes  |  more than 2 years ago

justthinkit writes "I have a number of applications that will not run on 64-bit Windows, but I would like to gain the benefits (most better caching) of having more than 4GB of RAM. Am I stuck with these Windows operating systems? And why is Windows Server 2008 Datacenter and Enterprise not included on that page? Should I go with a Linux or Win 7/8 system, and run a VM of Windows XP? Is this a solved problem or a lost cause?"

Why do you hate your printer?

justthinkit justthinkit writes  |  more than 3 years ago

justthinkit writes "After buying the big black ink cartridges for my Canon Pixma printer, only to have them be ignored while I use up the other inks, despite having my printer set to "grayscale", I am ready to buy another printer. Thanks to Slashdot I've learned to go back in time to the era of laser printers, only now I need to choose the best one of those. We need to print & scan, with almost zero faxing. I have narrowed my search down to an HP LaserJet Pro M1212nf or a Canon MF4450 but there seem like dozens of printers I could choose from. Since printers are practically free, and their supplies practically gold-plated, it comes down to which printer will I hate the least?"

Have you Bumped someone today?

Does anyone see any opportunites or problems with this kind of service?"

What gadgets go on your pedalled ride?

Anyone using the compressed air horn that fits in your closed fist and taps a supply of air in a bottle the size of a water bottle? I could see semis & dump trucks flipping over when they heard it. How about an electric motor add-on — is it worth the weight? Share your best bike secrets and maybe save a life."

What does Ubuntu mean to you?

justthinkit justthinkit writes  |  more than 6 years ago

justthinkit writes "Apparently, Ubuntu means a lot more than "easy to use Linux" to Doc Rivers and the Boston Celtics. For the NBA team it has become a rallying cry. Translated as "I am because we are", the Celtics break huddles with UBUNTU! (and have made it all the way to the NBA final as a result). So what does Ubuntu mean to you? Is "collective success over individual achievement" what Linux is all about? Or is this moment going to be more like what happened to Tux at Indy?"

Favorite application of all time?

justthinkit justthinkit writes  |  more than 7 years ago

justthinkit writes "Slashdot readers, you are the most technical people on Earth. You probably average a decade or more of computing experience. What, in all your years of hacking, have you found to be your favorite application of all? What is the one program you would like to have with you on a desert island? And why?

The catch is it has to be a single file and no dependencies other than what the OS of its day provided by default. This is a blast-from-the-past seeker. I am sick of OSes today shipping with hundreds of thousands of files, on install DVDs. I am looking for the most useful yet tiniest ever. Small is indeed beautiful (and Word.exe's chief architect should be President).

I'll kick things off by stating mine — Microsoft Word for DOS, version 5.0a [Version 5.5, patched for Y2K, is available from MS for free]. My choice: Word.exe, 622,428 bytes.

Some of the reasons I love Word.exe? Ran native on OS/2, had a shallow mouse-and-keyboard accessible menu tree (that negated the need for obscure WP-like macros or keyboard templates, although it had one of the best keytemps ever), integrated support for a powerful yet readable macro language, RTF support, embeddable images, CR or CR-LF text file support, changeable screen resolutions (including a half readable graphics mode), first DOS application with native mouse support. And practical things like a hefty 8MB file size limit, auto-created backup files, auto-generated "DOC" file extension, automatic on-screen pagination and absolute 100.0% stability. Pity that XP broke the clipboard access...

At one point I worked at a 500 person engineering firm that was still running Word.exe right into the Windows 98 era. I've written applications that depended on automated calls to Word.exe. Low tech, high age friends of mine use Word.exe to write, manage contact lists and convert documents — for almost 20 years now [timeline]. They bought a new printer 6 or 7 years ago and the dealer installed Windows to install the printer drivers. On their next trip to British Columbia, on route to Hawaii, I was called upon to put it back to "just DOS + Word" for them. Word.exe keeps on keeping on.

If we allow more than a single file but still limiting things to what shipped with the core application, then I would also cite: postscript support (30KB), superb help file (105KB), the most complete spell check database at that time — that allowed user and global add-on dictionaries (180KB), full thesaurus (320KB), excellent tutorial system for mouse and keyboard (900KB)]. Heck, if you excluded the thesaurus & tutorials you could be fit it all on a single bootable 3.5" floppy.

Ok, I think I set the bar pretty high but I am really looking forward to other all-star submissions."

justthinkit writes "John C. Dvorak is at it again, but this time he might be making sense. In a brief piece on pcmag.com he writes about Windows copy issues, calling the words "Preparing to copy" the "Windows' words of doom". His observations range from show-stopping bugs like the "The Long-Filename Anomaly" to annoyances like poor time-to-completion estimates. He doesn't add Vista's new copy slowdown feature to the list, probably hoping that Vista will just go away altogether. So is it time to cut him some slack?"

justthinkit writes "ZDNet reports that "Microsoft has sold nearly 40 million copies of Windows Vista in the first 100 days, twice as fast as the introduction of Windows XP, Microsft [sic] chairman Bill Gates said in a keynote address Tuesday." Is it just me or do the words "Reality distortion field" come to mind? Bill Gates then added that "sales of Vista in the first five weeks have matched 'the entire installed base of similar software'. Given there are 300 million+ computers in operation, each of which has an operating system, what are we to make of such a bizarre statement?"
