FreeBSD Developers Will Not Trust Chip-Based Encryption

CoderJoe Re:what's that going to accomplish? (178 comments)

This article talks about Intel's design, which is based on two inverters in a ring. Both inverters are forced to the same state and then left to settle into one state or the other based on thermal noise. There's a bit more to it, but that is the basis.

DARPA's Headless Robotic Mule Takes Load Off Warfighters

CoderJoe Re:Coulda swore... (210 comments)

Boston Dynamics has been working on varieties of this concept since the late 1990s or early 2000s. In 2005 they came out with a lighter version called BigDog. (The LS3 is apparently the next phase of the BigDog project). Here is a video from 2006: https://www.youtube.com/watch?v=mpBG-nSRcrQ

The Trouble With Bringing Your Business Laptop To China

CoderJoe Re:Industrial espionage (402 comments)

How about just doing a boot-time truecrypt volume? They can't boot the system from the hard drive, and booting from a live CD/USB is also useless, as the data on the hard drive is encrypted. (unless they want to take the time to image the whole hard drive so they can work on cracking it elsewhere)

US Navy Funds 'MacGyver' Robot

And then, when the ship's computer is damaged, they open several time windows into 18th century France for a replacement?

Anonymous' Barrett Brown Raided By FBI During Online Chat

CoderJoe Re:Just self defense (208 comments)

Even in a no-knock raid, if you fire on the police, and especially if you kill one of them, you are going to be in for a world of hurt from the brotherhood of blue.

Microsoft Engineer Discovers Android Spam Botnet, Google Denies Claim

CoderJoe Re:Why not? (152 comments)

Now try again, without requiring flashing a custom OS version or root. The average user is not going to do any of that.

US District Court: Game Elements In Tetris Clone Infringe Tetris Co.'s Copyright

CoderJoe Re:Oh good (138 comments)

Now, there very well may be some people who create something and live off it for the rest of their lives without creating another thing. So what? If someone creates something so wonderful/critical/popular that it still generates income 50 years later why shouldn't they benefit from that?

Ok, so how does having copyright last until 75 years AFTER THE DEATH of the author benefit the author? They're worm food.

As far a Disney, they take from the public domain, but do everything in their power to prevent their works enriching that same public domain. In addition, after they make their work, they may attack anyone else approaching that same PD source work for another project. Plus, they don't always have the rights they think they do when creating a work (example: Winnie the Pooh by A. A. Milne. Disney stepped well beyond the license they had to the work.)

Intel Dismisses 'x86 Tax', Sees No Future For ARM

CoderJoe Re:Speed versus complexity (406 comments)

ARM isn't "magical" and its been needing more and more extras like HD decoder chips to share the load because it simply can't get enough IPC to do the job on its own.

The last time I checked, x86 needed extras like the GPU to offload HD decoding to as well.

Flame Malware Hijacks Windows Update

CoderJoe Re:whoops (268 comments)

As for why, MS managed to lose control of (or whore out) the one true cert that all Windows installations are dependent on. In spite of that being public knowledge they haven't revoked it.

Except they did revoke it. That's what the emergency security update they pushed out yesterday was all about.

Hobbit Pub Saved By Actors Stephen Fry and Sir Ian McKellen

CoderJoe Re:Misleading Cause (169 comments)

Can you provide links to any of the promotional material that uses stills from the movies? I poked around on their site, and so far, all I have found are drawings and paintings. (Though the background on one looks very similar to Viggo Mortensen, though not exactly.)

iPhone Auto-Combusts On Australian Airplane

CoderJoe Re:Ban phones with nonremovable batteries (277 comments)

I'd rather have twice (or more) the battery life per charge than a removable battery which is one reason I have an iPhone 4S instead of an android handset.

Where are you going to keep those extra batteries that you have to swap throughout the day when you are not on a plane? What happens when you have then in your pocket with some keys and one of the keys short the terminals on a battery in your pocket?

Who said anything about carrying extra batteries? Let me count the number of times I have carried an extra battery for my phone (android or other) since phones changed from analog to digital carrier: never.

Having a removable battery allows for several things, such as removing the battery when something goes wrong (or to prevent it from going wrong), or replacing entirely when the original battery has worn out.

Ask Slashdot: Recovering Data From 20-Year-Old Diskettes?

CoderJoe Re:The wisdom of using compression in archives (375 comments)

DEFLATE (which is used in gz files) also has a blocking mechanism. the problem is there is no magic value to search for like there is with bzip2. However, it is possible to recover data after a corrupt section of a tar.gz file. I know because I have done it just this month. "stored" blocks happen to be laid out in such a way that you can actually scan for them. once you find a stored block, you can then attempt to decode the deflate stream from that point. As long as no compressed blocks refer to data before that stored block, you've recovered data that you previously chalked up as lost.

Ask Slashdot: Recovering Data From 20-Year-Old Diskettes?

CoderJoe Re:Norton Disk Doctor (375 comments)

3.5" and 5.25" floppy drives are generally quite dumb. they have no idea what a sector is. These are called "soft sectored" disks. The drive just streams flux reversal pulses out over the /READ_DATA line to the controller card. The controller is where the sector is decoded.

Ask Slashdot: Recovering Data From 20-Year-Old Diskettes?

CoderJoe Re:Specialized controller devices... (375 comments)

BTW, I have also checked and adjusted the calibration on a few different 3.5" drives. I don't have test media to check the alignment of a 5.25" drive, currently.

Ask Slashdot: Recovering Data From 20-Year-Old Diskettes?

CoderJoe Specialized controller devices... (375 comments)

What method are you using to read them? If just a USB drive or an internal drive on a normal floppy controller, you might get better luck with a device such as the KryoFlux (if you are really determined to get that data back). It is a specialized floppy controller that records the timing of the flux reversals on the media, with the ability to sample a single track about 35 times in one pass, and retry many many times in an attempt to get everything. then software converts that to a usable disk image file.

If you are not interested on spending money on such a device, perhaps you could send the media to someone that has one. (Such as myself.)

Cybercrime Treaty Pushes Surveillance Worldwide

CoderJoe Re:Encrypt everything. (89 comments)

Sure, you can encrypt the data, but you still have layer 3 information showing what servers you're communicating with. And with the extensions to allow vhosts on https (with different certificates for each vhost), you might be able to tell what site is being visited by logging the handshake.
