FBI Studied How Much Drones Impact Your Privacy -- Then Marked It Secret

Isao Makes Sense (139 comments)

PIA's generally discuss the technology or system in terms of how it would be used by the agency. For the FBI, this would likely include different operational scenarios, and certainly how drone data would be used in investigations. I can understand that such information would reveal strategies and tactics. As long as is has oversight by somebody (a point of discussion, I know) I'm fine with it being marked For Official Use Only (FOUO).

Australian Police Use Telcos For Cell "Tower Dump" of All Connected Users' Data

Isao Re:What's wrong with so called postal zone dump (60 comments)

They actually already do "postal zone dumps" in the United States, in that the front of every single piece of mail sent through the Post Office is imaged and put in a database for law enforcement. They've been doing it for some time.

I had no idea this was being done.

Ask Slashdot: Experiences With Free To Air Satellite TV?

Isao Great hobby, essential to get ethnic programming (219 comments)

I've been running FTA receiver setups in the US for about a decade, so my data comes from that. My own setup uses 3 dishes (one with multiple satellites), and I operate two others at different locations. I have relatives in Europe who've been doing this for longer, and it's very easy and common over there. It's pretty rare in the US. I started because some family members wanted to receive ethnic programming in their own languages and I love to experiment. It requires some practice to set up and aim, but is very doable and doesn't have to be expensive. You can get started under $300US. Take a look at Sadoun in Texas. He also has a lot of information for beginners.

You'll need a dish (typically 90cm), somewhere with a view of your selected satellites to plant it, an LNB to go on the dish (Low Noise Block Amplifier, the actual "antenna"; the dish is just a reflector), a bunch of RG6 cable leading to your TV, and a receiver.

Before buying all this, take a look at the various satellites and channels available to you, and pick a starting satellite. You'll need to be sure that you have a clear line of sight to the "bird". A great site for this is lyngsat. In the US I suggest starting with Galaxy 19, which has several hundred channels on it.

Summarizing the rest, plant the dish, aim, and scan with your receiver to program the channels. You can get all sorts of things regularly, and occasional "wild feeds" that aren't intended for public consumption. There's also encrypted video, which is either pay TV, private company channels (like Ford, etc.) or network backhauls.

Later on you can get into multiple satellites, either with multiple LNB's on one dish, multiple dishes and a switch, or a motorized (!) dish. They're all fun.

It's a lot of fun, and can be a great intro for kids to electronics, radio reception, satellites, orbital mechanics, space, etc.

Should the US Really Limit Chinese-Government Influenced IT Systems?

Did Steve Jobs Pick the Wrong Tablet Size?

Isao Jobs did marketing and spin, and very well at that (433 comments)

Steve Jobs is FAMOUS for deriding products/features not currently delivered by his company, followed by releasing exactly those features some time later when the market is ready for HIM. (iPod with video, for example.) His strength of personality (and strong products) let him get away with it repeatedly, and few observers ever held him to task for it. The problem with the iPad Mini is that he wasn't around to push it through with his charisma. Clearly it was in the works before he died, and I doubt anything "in the works" would not be known to Jobs.

Iran Says It Sent Monkey Into Space and Back

Facebook Testing $100 Fee To Mail Mark Zuckerberg

Isao Pay me (228 comments)

I love it, go for it Zuck! This is clearly a preview of a roll-out to the general user base, where anyone, including advertisers, has to pay a user to send them messages (unless they're already accepted as a friend). This is great! Monetize advertisers (FB takes a transaction fee), and incentivise users to accept advertising an their own terms. I bet the next version of this will include topic and interest filters, so you can discount the fees on things you might actually like to hear about, and raise them on the noise. I'd only charge $0.50 to hear about a tech item, but $100 to hear about a Justin Beiber concert. Works for me, where do I sign up?

The Secret To Iranian Drone Technology? Just Add Photoshop

Isao Re:Well, at least they have artists in Iran (183 comments)

The SAVAK were a lot of fun for the population. And they had help from the CIA. The educated and wealthy classes liked the Shah, as their life was good under him (at least until the country ran out of jobs for them). The poorer, less educated citizens mainly got the boot, if they interacted with the regime at all. Since the US and Britain put the Shah on the throne, those countries weren't loved by the rebellion. And yes, I think Khomeini made a mistake letting the student rebels put the embassy hostages between him and the West. Iran has been on the short end of that stick ever since.

How Doctors Die

Isao Re:The Sanctity of Life (646 comments)

Eventually the effective dose exceeds the lethal dose

Except that in only a few countries are you able to go that far. Most places require you to stop short of the lethal dose and live in excruciating agony for as long a your systems (and technology) will support you. Have a nice day.

UK Police Buy Covert Cellphone Surveillance System

Isao Re:Wireless Privacy??? (103 comments)

Another facet of this is that the devices can be tracked, whether or not the user is using it or making a call. As long as it is on and available to receive a call (communicating with the base) it can be identified and a coarse location determined. If it were me in the law-enforcement role, the way I would use this is to identify devices in an area of interest (the protest locations) and record the identifiers over a series of days/nights. Eliminating devices which did not appear during a majority of the observed days lets you focus on the core group of people present at the events. (This will include media, people who live/work in the area, police and civil support themselves, etc.) Some careful trimming of the data by time of day will help reduce the "noise". Then you have a subset to focus investigations on. If I were on the other side, I'd make good use of WiFi (fixed and hotspots), VoIP, and "burners" (prepaid phones bought with cash and no ID - don't know if that's possible in all countries). Those are easy protections. Defense can get more technical and fiddle with the device IDs, but that likely crosses a line - and I'd want to be pure as the driven snow if I was at high risk of being arrested at some point.

Ask Slashdot: Best Long-Term Video/Picture Storage?

Isao 3-2-1 Backup (499 comments)

First off, Congratulations! Including files related to my 4 year old, I've got about 100GB of media. I recommend the 3-2-1 Backup method: 3 copies of the data, on 2 different drives/media, 1 of them off-site. I do this by having a "primary" copy of the data on a machine at home, which I copy to a backup drive periodically. The primary also gets rsync'd nightly to a cheap eeePC with a 1 TB USB drive in a closet at my parents place. All this is running Linux, but you can manage with other OS's. Bonus #1: They get local access to the media via an SMB read-only share. Bonus #2: I gave them a writable share for THEIR data, which is rsync'd nightly to our place as a backup. You can do this with friends, etc. Being on the same ISP helps as the sync traffic can stay in the provider cloud. I've also used Amazon S3 (~US$13/month for 100GB of non-redundant storage) and I still use rsync.net for more limited critical documents (encrypted), though their price doesn't scale well for large, static data sets (they don't charge for bandwidth so relatively small but dynamic data is a good fit).

SignalGuru Helps Drivers Avoid Red Lights

Isao Re:You can do that right now (436 comments)

No, s/he's talking about the ECU dropping the injector dwell to zero because the accessories can be run from the inertia of the car. Engine revs come from the wheels/transmission, not combustion, actually a lot like a hybrid's regenerative brakes. You can actually watch this happen in reverse when you get close to stopping because the revs are too low to sustain drive and the ECU starts fuel flow again, causing a slight blip in RPM as it transitions to idle. (This is also when the transmission disengages.)

Wait a minute, I think I've seen this before...

"The future could see smartphone's containing as much processing power as your current desktop."

"So I'll have to wait 5 minutes before my smartphone has finally booted?"

Yup. Same as it ever was. Next up: Implant boot times.

Why IT Needs To Change for Gen Z

Isao Re:Why Gen Z Needs To Change for Work (443 comments)

Some provide a choice: company laptop with maintenance or your own device but you do the maintenance.

I can't wait for this, and the ensuing lawsuits. Am I lawsuit happy? Perhaps, but the first time client PII or similar data is lost through this practice, there will be a lawsuit faster than you can say "failure to perform due diligence".

That said I believe there are "right" ways to do this. Virtual machines, remote desktops, mobile apps, sandboxes, etc. My company has no problem buying an employee a Mac or Linux machine or iPad when the work really requires it. With apologies to MasterCard, for everything else there's VirtualBox.

Asia Runs Out of IPv4 Addresses

Isao Re:geographic distribution (321 comments)

I say we fix this oversight from 30 YEARS AGO by developing a new addressing scheme, compatible to an extent with the original, that can be overlaid on the network and distributed more evenly around the world. Oh, and make it bigger, too, so we don't revisit this problem for a while. Who's in?

Ford Building Cars That Talk To Other Cars

The IntelliDrive program has been working on this for a while, and the OEMs are starting to test this on the road. You can look at some concept videos.

The RF band is around 5.4GHz, allocated specifically for short-range transportation communication.

Making Airport Scanners Less Objectionable

Isao Re:Deadlier than the terrorists (681 comments)

I don't like the backscatter machines OR the pat-downs, but I saw this and it raised some questions. Now I'm a Schneier fan-boy, and we even work in the same field, but let's take the NY 9/11 attack as a comparison (2819 according to NYMag).

So for the scanner to be deadlier than just that attack, it would have to kill 16 extra people a year for a bit over 176 years. Am I missing something?

For further comparison there's an 9/11-equivalent loss of life on US road every 27 days (using 2008 numbers from the 'pedia.) Maybe it's me, but I don't see it being more deadly than terrorists. That said, I'm not going in them - radiation is cumulative. RF (the MM-wave scanners) is not.

Japan's Latest Rockstar Is a 3D Hologram

Isao Re:Norman Spinrad had him beat by almost a decade (305 comments)

"Eve Tokimatsuri" from Megazone 23 came out in March of 1985. Note this is an Anime OVA, and I suspect influenced the desires of the folks working on Hatsune Miku. My only remaining questions are when the aliens attack our Dyson Sphere-like satellite city, and where to get my Garland prototype.
