Actually I lived 7 miles from work, 1 mile from a grocery store, and 0.7 miles from light rail that went to major shopping centers and had a $400 GT bicycle with $50 panniers on it. I've seen people do bulk runs to Costco on touring bikes (different geometry and gearing, made to haul 200lb of shit around) with specially designed trailers that hook up to your bike (they're about $200-$500; the ExtraWheel is the most maneuverable, but really big bulk storage comes with some of the less slick ones. You can't put a crate on an ExtraWheel).
Roads were invented because of bicycles. Bicycles would scare pedestrians--too fast, dangerous, heavy. Paved roads allowed for easier, faster transit and isolation. In some cities, a bicycle gets you around better than a car--Baltimore City is like that, try driving down by the Inner Harbor and it's a mess, a bicycle can keep up with traffic (pass it by driving illegally, but that's bad--don't run lights and don't weave through traffic... though the right lane is dedicated bicycle/bus in a lot of the harbor area so usually you DO blast past traffic!). Parking is expensive and you're usually a mile away from anything interesting, but the bike you lock up out front of the Barnes & Noble and you're right at Barnes & Noble instead of 6 blocks away (it's a 3/4 mile walk from the $8 parking garage to the B&N, or $20 to park in one of the ones 4 blocks away for more than 2 hours).
Bikes won't get you 20 miles to work unless you're really hardcore or traffic is really that bad. I mean if you got it and you're going to sit in traffic for an hour and a half, but you can pull it off on the bike in the same time (or less--bike lane at 20mph...), go for it. New York is like that, but they have public transit that's much more reasonable. Mass transit here takes 3 hours for a former coworker to get to work, while he makes the bike ride in 2 and it's work, so he bicycles there and doesn't buy a bus pass--on a $20 ducati, which by the way does fall apart every few weeks (hence why I have a real road setup hybrid bike, that plus it's actually easier to ride). For the average person I would say 5 miles is reasonable, and if you can't do it then you can get up to it in a few weeks. After that, the time difference or the amount of endurance needed starts increasing sharply and it's no longer feasible; can't fault someone for commuting 60 miles in a car instead of a bicycle (maybe you should move closer to work...).
For me it took me 39 minutes to drive to work and 45 to bicycle it, stopping at all traffic lights and stop signs with local law stopping (Idaho law says bicycles and motorcycles can stop at a red light, verify no cross traffic, and then proceed through; Maryland law specifies that bicycles and motorcycles must wait for green, and pedestrians cross with the light--i.e. red light means pedestrians get a do-not-walk). It put less wear on my car, cost me about $100/mo less in car insurance (full coverage, I drive a lot less and so I pay less insurance--blame me for having a car loan instead of buying in cash), helped me feel much more awake at work, sleep better, I even became slimmer but stronger.. more muscle tone, less flab, for an investment of 12 minutes a day. Grocery trip was 10 minutes driving in the city, or the same time on a bicycle because I always caught the same lights anyway. Light rail ride was longer than driving, but cheaper than gas, and I could read books on the light rail--I can't read books while driving, I swerve all over the road.
I wouldn't bicycle the 15 miles uphill to Hunt Valley and back. I have gone the 9 out to H-Mart, a few times, just to do it. Usually I drive that because usually I get fish!
Anyway I could do this all day, but eh. Bicycles, motorcycles, public transit... my parents tried to convince me riding the bus or light rail was infeasible as a form of transit, but that's what I do these days. I own a car, I drive, but I also bike around and ride rail. Don't take a 50cc dirt bike on a cross country highway trip; don't take a $20 ducati as a bicycle for serious commuting (or mountain biking, never do that unless you want to die when your bike shatters).
I strongly suggest the Google Nexus 7, and perhaps put Cyanogenmod 10 on it depending on your needs. Cyanogenmod 10 is definitely a plus; the question is does it meet HIPPA, or more precisely if it's compromised can you be blamed for using CM10 versus nobody (even Google, they didn't supply this for HIPPA) being blamed for using what came standard?
Also see the "Bicycles are toys" crowd, versus the people who have no car and don't pay insurance/gas/car payment and are happily bicycling to work, to school, grocery shopping, etc.
Uh, no. Maybe with rainbow tables calculated ahead of time, but the hashes are MD4 and not really easily cracked. On the other hand, the actual password used is needed to generate the encryption key for EFS--an MD4 collision isn't "close enough". Physical access always gets you authentication, but it won't get you the actual password (you can't use what you get to log into other accounts with the same password--ie bank accounts) and it won't get you encryption keys.
$51,914 is the median income, I make $65k, and they're like "ok so you're an out-of-touch rich asshole." I was an out-of-touch rich asshole when I made $45k too; apparently I'm rich until I make minimum wage.
All I can say is you motherfuckers suck with money and that's why you're poor. When I'm making $80k or so we can talk about me being rich because my income's high.
No, I don't consider $1300 to be a lot of money. I'm going to throw about that much to fix the roof and some brickwork. Also sump pump, going to buy TWO furnaces (a hydronic off the water heater and one sized for the house that's dedicated to heating the water heater as a back-up), and install a new 400L water heater (solar driven, so it'll provide solar heating and hot water free, plus I get 5 SREC worth about $200 on the market these days per year; if the tank goes cold, the gas furnace will kick on and heat the tank).
My expenses are high, some $20k/year. I intend to slim that down to about $4000/year within the next 4 years. That includes food, gasoline, my home, car insurance, home insurance, utilities (gas, electric, phone). I'll be eliminating my mortgage, my car loan, a fair chunk of my heating bill, half my car insurance (removing collision since I don't drive much and I'll save up money to buy another car if I destroy it), and part of my food bill (by cooking more at home). Just my rent at the apartment was $9000/year.
Hell at that level I could just buy one of these empty houses, rebuild them, and let HUD rent them out for me. They'll give me $500/mo, that's like $6000/year. The burn-outs around here aren't worth fixing up because you'll never recover your costs (unless you do the work yourself), and the neighborhoods suffer. I could fix several up and rent them or sell them, tidy up the neighborhood some, and in short order the income would make me quite comfortable... then I could quit this white collar shit, pay a management company or HUD to do all the work for me, and just go build houses for a living. Something that feels like I'm actually doing something.
Not true. I rented for the longest time because owning would have been out of my reach. I had excellent credit, but the P&I on a house smaller than the one I have at 3% would have been $1200(!) and it was only 1.5 times the size of my $750/mo apartment. On top of that came PMI and property taxes, it would have been about $1500/mo, plus maintenance. Home owners insurance is about $400/year too but that's like $30/mo.
Buying is cheaper than renting NOW. It's a good time to buy.
A 42 inch TV isn't huge. I personally have a 32 inch and, while I think it's massive, I recall projection TVs being popular in 2000 that were 6 feet wide. We're talking 6 feet of 3:4, so think 5/3 of 72 inch that being 120 inch diagonal. Now I mean I've seen the $30,000 plasma TVs that are that big, but this is a $3000-ish projection TV. That's gimongous.
I've routinely seen people on food stamps complaining about their $150 cable TV or satellite bills, although now satellite can be had for $20/mo unless you have all the movie channels. I've seen a few people bitch that they couldn't afford rent and can't handle the $300 cable TV bill, which is a wtf for me. This happens in this city. Food stampers with $150-$300 TV bills.
$1750/mo is livable for me, if you mean after taxes. Once I pay off my car loan, lower is livable. It's tough, but that's because I've done things that I shouldn't have done if I had a tighter budget.
$300 is a lot of money? Are you kidding me? Dude, I work a white collar job at like $65k/year. I have a mortgage to pay on an 1800sqft house. $300 isn't a lot of money. They get broadband for 10 years with no fee, that's like $2.50/mo
I spent $350 outright on my Galaxy Nexus so I didn't buy any $50 contract phone for 24 months with a +$20 bill ($480 + $50 = $530 for the phone, no I spent $350). I have a watch that costs more than my mortgage payment. I pay my mortgage and my car payment every month and I still save up an extra 3 mortgage payments and a car payment (I'll have that house paid off shortly).
I mean seriously, the most basic welfare and unemployment necessity costs more than $300 and requires paying more than a $100 monthly fee to use, and burns like $50/mo in electricity.
Look at Victorian era pornography. Erotic novels involving beating, rape, bestiality, pedophilia, etc. Even I can't stomach that stuff (then again I'm weak on sexual stuff).
I was raped as a child at the age of 7 and I am also a victim of child pornography as well. Chances are they're those images/videos of me being raped floating out there somewhere on the internet. Knowing that there are people pleasuring themselves to images and videos of me being brutally raped gave me extreme PTSD as a teenager.
I can accept this.
What I can't accept is the line that the government hands down: "every time someone looks at an image of child pornography is another victimization of that person." Investigators have hash databases and such to identify known images; in a whole prosecution, from start to finish, there may be absolutely nobody who actually sees the image. Like, the image never comes up on screen. This is because every time you double-click the JPG, it's considered identical to raping that person again.
Now honestly, I get that "it's out there and it bothers me" is a thing. But I don't see how that comes to "each single instance is terrible" in any way. It's out there. Obviously we don't want to put this up in front of the court for the whole world to see. Maybe not the lawyers. A special investigator can testify that, yes, he saw the images; that's fine, it's his job, he's background checked, we trust this guy to say "oh that was a picture of a beagle" if it was a false positive. We can't do that because apparently the victim is made a victim all over again if the single investigator pops it open for a quick visual verification.
You can imagine how this works when they find a new picture.
But at the same time, I'll say, put them away, preferably before they cause trouble.
So wait, are you advocating jailing people because of the thoughts in their head? I'm trying to understand this. It looks like you're admitting there's a non-issue here with the actual "crime" of possession, but that what the possession implies is important and we should jail these people.
Victorian pornography--text, words, stories written--included a lot of stuff. Bestiality, child porn, a lot. Are you advocating thus that the thoughts are the crime, and people who read such things should be jailed or put on some sort of probation or under supervision? What about those who don't? The moment you let it slip that you have thoughts like that dance through your head at times, you should be put under some kind of arrest or monitoring?
Are we to keep our thoughts secret? Are we to keep a straight face at all times, smile, praise the current government, worship the great deeds of America in keeping the world safe, agree that the Muslims are evil and must be destroyed, and loudly proclaim that children are not sexual and display our firm belief in this by jumping to destroy anyone whose eye twitches with uncertainty when the topic comes up?
The Tegra 3 only runs in a mode with 4 cores running at once, or in a low-power single-core mode on a low-power-consumption core that should top out at 500. OMAP specs say it's dual-core, I would hazard a guess that the 2 M3 cores are also low-power cores and it doesn't run all 4 at once just like the Tegra 3 doesn't run all 5 at once.
Also, if you want to use (n) keys to reconstruct, you use a finite field and plot a polynomial of degree (n-1). Two points? Plot a line. Three? Quadratic. Four? Cubic. Take four points on a cubic polynomial and run gauss jordan elimination, and you get an equation that generates ALL the points. Then pull the Y intercept as the key. So take key K and generate (rand1)x^2 + (rand2)x + K and pull 15 points, use any 3 points to solve for rand1, rand2, and K.
No, the problem isn't that you're storing the key; the problem is you have to store the key. If you take 50 uniqueness points from a fingerprint, you'll get 50 points that are almost close enough. You don't get numbers {3, 7, 15, 29, 37, 42} and then again get {3, 7, 15, 29, 37, 42}; what you get is {3, 7, 15, 29, 37, 42} and you store that, and when you plug in you get {3, 8, 14, 27, 36, 44} and that's close enough that it's 99.99% likely to be the same fingerprint. If you generate a key with {3, 8, 14, 27, 36. 44} it won't match the key you generated with {3, 7. 15, 29. 37, 42} and you won't be able to decrypt shit.
Except that with the NTLM2 hashes, you can't use the hash to get the password and thus can't use the password to decrypt EFS files. With the system you described, I can boot a Linux LiveCD and copy out all the passwords for all accounts, and then log into anything directly and decrypt any encrypted files I want.
Ridiculously hard. Fingerprints are biometric, they change. You have a rough model that's similar to a rough model snapshot of your fingerprint pressed, squished, scanned, etc. Your print may possibly be rotated--orientation is random, but comparable to a known snapshot. Basically every time you image the fingerprint you get a slightly different result, and you apply fuzzy logic to work out if it matches prior data.
This also means that using fingerprint uniqueness points to generate some sort of AES key would store your password in plain text: the finger print is stored somewhere for verification, and therefor the finger print model can be used to derive the encryption key, and thus the key is stored with the ciphertext, thus plain text. (By this logic, if you attach your front door key to your front door with a magnet and then lock your front door and leave, your house is unlocked--any moron can pluck the key dangling by the door knob and open your door, you've simply altered the interface a bit. Key under the doormat is the same, takes a little more time examining it to figure out how you're supposed to open the door but you can, it's not really locked.)
Basically if the fingerprint scanner integrated with Windows Login the same way as third party login systems like Novel Networks et al, it wouldn't need your password until you tried to access an encrypted file. The flaw here is they hack it out by sending your password to Windows; fingerprint data is too noisy, you compare it as "sufficiently similar" but it's going to be too unique to generate a key from with any repeatability and high entropy. Thus they store the key UUENCODED or BASE64 or MIME to obscure it, which doesn't work on hackers. Instead, they should hook the login process and directly complete user authentication without a password, and let windows ask for a password if it tries to touch an EFS file.
I understand that both of these things use the same processor core design, and that they're within 5% of each other in terms of raw single core speed, and that one of these has twice as many cores available and so if you ever DO peg the system with a couple threads or have it under enough continuous load that you might have to wait a moment to halt a process and state save and context switch out to the interrupt handler and new process (i.e. screen draw, etc) that you won't get lag and jerky responsiveness.
Of course a modern phone currently won't load an OMAP 4470 enough for this to be an issue. But really, they're the same thing, just one at its highest tier clocks its execution unit 100MHz slower than the other, and the other at its highest tier has the ability to concurrently run only half as many execution threads. The half as many threads thing is the bigger of the two. FFS they're SOC with integrated memory controllers and north bridges and such, everything is right there, they're both well-tuned systems.
This is like saying a dual core 3.0GHz Core i3 Intel outperforms a 2.8GHz Core i5 Intel. It's a dumb statement from the more-gigahertz crowd who measure everything by FPS in Doom 3 and think 100MHz is massive.
Yes but in this case the nominal clockrates are the same and the fastest clockrates are a whopping 5% away from each other at 100MHz distance. If you have a single task keeping your processor pegged above 95% for any appreciable time (a few mS for an interactive task like drawing the screen), you have other problems or you're doing a batch task that should only take a few seconds anyway.
The fact of the matter is having 4 cores helps when your phone is your media player and you want the OS to be able to do housekeeping in the background, respond quickly to user inputs, keep the screen updated, continue animating that live wallpaper, get your e-mail, download a text message, etc. Hell, watching video is insane because you have to de-encapsulate the video (i.e. out of the OGG/AVI/Matroska container) and then simultaneously decode audio and video in real-time (called Demuxing). If you tap the screen and have to wait 40mS for free processing power instead of 1mS, the phone lags ever so slightly and you say it's "a little jerky". You can no longer smoothly slide the system bar open from the top.
Between the two, 5% CPU power isn't going to make a damn bit of difference and 2 extra cores is going to make your phone way more responsive if it ever does happen to be loaded in a way that makes that 5% suddenly important.
OMAP 4470 "Can outperform the Tegra 3"? The Tegra 3 has 1.2-1.7 GHz QUAD CORE ARM Cortex-A9 application-optimized cores with NEON. The OMAP 4470 has 1.5-1.8GHz DUAL CORE ARM Cortex-A9 application optimized cores with NEON. You know that means the slowest Tegra has 1/3 more processing power available than the fastest OMAP 4470, and its single-core speed is 2/3 that of the OMAP? If you went with the Tegra 3 T33 used in the Asus T700 at 1.7GHz, you'd have 95% of the single core speed and 90% more total processing power available.

Actually I lived 7 miles from work, 1 mile from a grocery store, and 0.7 miles from light rail that went to major shopping centers and had a $400 GT bicycle with $50 panniers on it. I've seen people do bulk runs to Costco on touring bikes (different geometry and gearing, made to haul 200lb of shit around) with specially designed trailers that hook up to your bike (they're about $200-$500; the ExtraWheel is the most maneuverable, but really big bulk storage comes with some of the less slick ones.

So wait, are you advocating jailing people because of the thoughts in their head? I'm trying to understand this. It looks like you're admitting there's a non-issue here with the actual "crime" of possession, but that what the possession implies is important and we should jail these people.
Victorian pornography--text, words, stories written--included a lot of stuff. Bestiality, child porn, a lot. Are you advocating thus that the thoughts are the crime, and people who read such things should be jailed or put on some sort of probation or under supervision? What about those who don't? The moment you let it slip that you have thoughts like that dance through your head at times, you should be put under some kind of arrest or monitoring?
Are we to keep our thoughts secret? Are we to keep a straight face at all times, smile, praise the current government, worship the great deeds of America in keeping the world safe, agree that the Muslims are evil and must be destroyed, and loudly proclaim that children are not sexual and display our firm belief in this by jumping to destroy anyone whose eye twitches with uncertainty when the topic comes up?
The Tegra 3 only runs in a mode with 4 cores running at once, or in a low-power single-core mode on a low-power-consumption core that should top out at 500. OMAP specs say it's dual-core, I would hazard a guess that the 2 M3 cores are also low-power cores and it doesn't run all 4 at once just like the Tegra 3 doesn't run all 5 at once.
Also, if you want to use (n) keys to reconstruct, you use a finite field and plot a polynomial of degree (n-1). Two points? Plot a line. Three? Quadratic. Four? Cubic. Take four points on a cubic polynomial and run gauss jordan elimination, and you get an equation that generates ALL the points. Then pull the Y intercept as the key. So take key K and generate (rand1)x^2 + (rand2)x + K and pull 15 points, use any 3 points to solve for rand1, rand2, and K.
No, the problem isn't that you're storing the key; the problem is you have to store the key. If you take 50 uniqueness points from a fingerprint, you'll get 50 points that are almost close enough. You don't get numbers {3, 7, 15, 29, 37, 42} and then again get {3, 7, 15, 29, 37, 42}; what you get is {3, 7, 15, 29, 37, 42} and you store that, and when you plug in you get {3, 8, 14, 27, 36, 44} and that's close enough that it's 99.99% likely to be the same fingerprint. If you generate a key with {3, 8, 14, 27, 36. 44} it won't match the key you generated with {3, 7. 15, 29. 37, 42} and you won't be able to decrypt shit.
Except that with the NTLM2 hashes, you can't use the hash to get the password and thus can't use the password to decrypt EFS files. With the system you described, I can boot a Linux LiveCD and copy out all the passwords for all accounts, and then log into anything directly and decrypt any encrypted files I want.
Ridiculously hard. Fingerprints are biometric, they change. You have a rough model that's similar to a rough model snapshot of your fingerprint pressed, squished, scanned, etc. Your print may possibly be rotated--orientation is random, but comparable to a known snapshot. Basically every time you image the fingerprint you get a slightly different result, and you apply fuzzy logic to work out if it matches prior data.
This also means that using fingerprint uniqueness points to generate some sort of AES key would store your password in plain text: the finger print is stored somewhere for verification, and therefor the finger print model can be used to derive the encryption key, and thus the key is stored with the ciphertext, thus plain text. (By this logic, if you attach your front door key to your front door with a magnet and then lock your front door and leave, your house is unlocked--any moron can pluck the key dangling by the door knob and open your door, you've simply altered the interface a bit. Key under the doormat is the same, takes a little more time examining it to figure out how you're supposed to open the door but you can, it's not really locked.)
Basically if the fingerprint scanner integrated with Windows Login the same way as third party login systems like Novel Networks et al, it wouldn't need your password until you tried to access an encrypted file. The flaw here is they hack it out by sending your password to Windows; fingerprint data is too noisy, you compare it as "sufficiently similar" but it's going to be too unique to generate a key from with any repeatability and high entropy. Thus they store the key UUENCODED or BASE64 or MIME to obscure it, which doesn't work on hackers. Instead, they should hook the login process and directly complete user authentication without a password, and let windows ask for a password if it tries to touch an EFS file.
I understand that both of these things use the same processor core design, and that they're within 5% of each other in terms of raw single core speed, and that one of these has twice as many cores available and so if you ever DO peg the system with a couple threads or have it under enough continuous load that you might have to wait a moment to halt a process and state save and context switch out to the interrupt handler and new process (i.e. screen draw, etc) that you won't get lag and jerky responsiveness.
Of course a modern phone currently won't load an OMAP 4470 enough for this to be an issue. But really, they're the same thing, just one at its highest tier clocks its execution unit 100MHz slower than the other, and the other at its highest tier has the ability to concurrently run only half as many execution threads. The half as many threads thing is the bigger of the two. FFS they're SOC with integrated memory controllers and north bridges and such, everything is right there, they're both well-tuned systems.
This is like saying a dual core 3.0GHz Core i3 Intel outperforms a 2.8GHz Core i5 Intel. It's a dumb statement from the more-gigahertz crowd who measure everything by FPS in Doom 3 and think 100MHz is massive.
Yes but in this case the nominal clockrates are the same and the fastest clockrates are a whopping 5% away from each other at 100MHz distance. If you have a single task keeping your processor pegged above 95% for any appreciable time (a few mS for an interactive task like drawing the screen), you have other problems or you're doing a batch task that should only take a few seconds anyway.
The fact of the matter is having 4 cores helps when your phone is your media player and you want the OS to be able to do housekeeping in the background, respond quickly to user inputs, keep the screen updated, continue animating that live wallpaper, get your e-mail, download a text message, etc. Hell, watching video is insane because you have to de-encapsulate the video (i.e. out of the OGG/AVI/Matroska container) and then simultaneously decode audio and video in real-time (called Demuxing). If you tap the screen and have to wait 40mS for free processing power instead of 1mS, the phone lags ever so slightly and you say it's "a little jerky". You can no longer smoothly slide the system bar open from the top.
Between the two, 5% CPU power isn't going to make a damn bit of difference and 2 extra cores is going to make your phone way more responsive if it ever does happen to be loaded in a way that makes that 5% suddenly important.
OMAP 4470 "Can outperform the Tegra 3"? The Tegra 3 has 1.2-1.7 GHz QUAD CORE ARM Cortex-A9 application-optimized cores with NEON. The OMAP 4470 has 1.5-1.8GHz DUAL CORE ARM Cortex-A9 application optimized cores with NEON. You know that means the slowest Tegra has 1/3 more processing power available than the fastest OMAP 4470, and its single-core speed is 2/3 that of the OMAP? If you went with the Tegra 3 T33 used in the Asus T700 at 1.7GHz, you'd have 95% of the single core speed and 90% more total processing power available.
There is no way you can outperform the Tegra 3.
It's called rent seeking.
