Session variables. If people would use those and not just cookies. It'd be better.
And how exactly do you think session variables work? How do you link a browser to the session? Cookies!!!
Yes, I know you can put a god damn session id in the URL query string, but that's annoying, unreliable, and insecure. IF someone navigates your website for a bit, puts some stuff in the shopping cart, then just goes back to your homepage by stripping everything but the domain name off the URL...TADA!!! You've lost their session!!! Or if they jump to a different part of your website via a bookmark from a previous session...TADA!!!! You've lost their session. Or if they copy their URL and pass it to someone else/post it on a forum...TADA!!!! Someone else is now using their session (yes, you can "solve" that issue by linking the session by a secondary authentication variable like IP, but then you run the risk of having your website broken for anyone that moves between IP addresses).
In short, I've never seen a good, clean, reliable way to link a user to a session that doesn't involve cookies. If you've got the magic solution to that, please...I'm all ears.
Now if you mean websites should only use session cookies instead of persistent cookies, and the "deny all cookies" option only denied persistent cookies (does it do that already? I have no idea), then yes...that is a workable solution for most cases. Off the top of my head, I think the only thing you lose there is the ability to persist your login between browser sessions. But then again, if someone doesn't mind session cookie but dislikes persistent cookies, they could already set their browser to clear all cookies on exit or use a private browsing mode, and then all current websites would work perfectly fine.
2. If it's software-based, it'll be cracked and pirated within a month of release.
You would think so, wouldn't you. However, Windows Media Center is software based, and yet (as far as I know) nobody has managed to crack it to enable open source software to mimic WMC and trick the cable card devices into giving full access to the Copy Once and Copy Never content.
Reading through the FCC's summary, I can't tell whether this is a good or a bad thing. In principle it sounds good, but certainly there's going to be some sort of certifications involved somewhere, and I doubt open source stuff like mythtv is going to be able to pass the requirements to get certified. Cable card may be less than ideal in implementation as far as open source is concerned, but at least there, if you've got a cooperating cable provider, you can access much of that content in it's digital form, which is better than the previous options of analog capture.
So the question we need to ask is whether, from an open source perspective, this is actually going to improve things for us (I'm definitely skeptical on that), keep it about the same, or make it worse.
I find the whole concept of Binge On very confusing, and it makes me feel like there's something fundamental I don't understand.
With typical wired service through your cable company, the most limited resource is on the other side of your ISP, and that's why the ISPs want to get websites like youtube and netflix to cache content locally to reduce that expense. With wireless service, of course that same resource limitation and expense still exists, but by far the much bigger resource limitation is between your phone and the cell tower. That's why cellular plans have much lower bandwidth caps than wired service.
So what sense does binge on make (from tmobiles perspective)? Yes, it reduces their outside bandwidth expense, but I thought that's kind of backward. Perhaps they'll save a few bucks on the backbone connectivity costs, but by making that content free from data caps, they're actually encouraging people to start using services they otherwise might not have used due to that caps, thus greatly increasing utilization of the more limited (and much more difficult to expand) wireless bandwidth.
Yes, it looks like it just replaces the WPS button.
Nope, the banana actually serves a secondary function. This whole thing is so poorly described, but if you click the reddit link in the summary, and then from there click the link to the original thread:
When you touch the banana, you get an 8 hour voucher for our guest wifi. (the 3 sec timeout is only for demoing) The PI has 5000, 8 hour vouchers. We are open ~200 days a year. If we have 10 guests a day, then this will work unattended for a couple of years easily.
So the purpose of the banana is to make it so novel that (along with the absolute lack of adequate instructions on the board) people are repeatedly touching the banana over and over again (not really sure of what is going on), thus ensuring that those 5000 vouchers don't last a month.
Police also often commit felonies like murder in the performance of their duties. We don't jail any cop who shoots a suspect, we investigate to determine if they were justified in doing so.
That's not murder until the investigation determines they were not justified. If they were justified, then its considered something else (not sure which term the law would apply....self defense? justifiable homicide? another term that applies specifically for police officers?)
In general I disagree with you. I'm alright with authorities having to set up more elaborate sting operations which require breaking laws to catch criminal. Maybe not your more contrived example of selling drugs indiscriminately and letting everyone run off, but I'd certainly support something like selling drugs in an effort to get further into a major drug organization in hopes of getting access to the top players in the organization. There are limits though. Selling drugs (to adults, not children/teens), fine. Committing murders, definitely not.
However, when it comes to child porn, I agree with you. I can have no tolerance for it. At no time, for any duration or for any reason, should the authorities be distributing it. After all, we've been told that child porn is SO dangerous to children that even the act of sharing CGI generated pictures (in which no child was actually harmed) is harmful to children. If distributing CGI child porn harms children, then just imagine how many children were harmed by these agents distributing ACTUAL child porn photos, in which children were actually directly harmed.
Now he's got throughput he can't actually use, but is missing critical functionality like wireless support.
I personally gave up on wireless support in my router. First problem I was always having was finding a router that had all the features I want. DDWRT is a priority for me, but finding a single device that 1) supports DDWRT easily (ie: doesn't rely on me finding a specific outdated revision of the hardware) 2) is cheap 3) has gigabit ethernet 4) good wireless 5) has a good amount of memory
Getting all of these in one device is difficult. The next problem is that I'd periodically end up with wifi issues. I had issues now and then with different device. Then I got my OnePlus One and the problems got worse. For some reason that device always has connection issues. It would continually get disconnected (so often that I couldn't even backup the videos from my phone via smb...it would always lose connection in the middle and I'd have to start over. It might take 10 tries before a video successfully copied over). I tried 4 different DDWRT routers I had access to (4 different device models from 3 different brands) and had the same issues
The last issue is dealing with power outages. All of my networking equipment is in the basement on a battery backup. When power goes down, I'm able to maintain connectivity and continue working from a laptop without issue. However, locating everything in the basement means I have OK signal on the first floor, and terrible to no signal on the 2nd floor and front/back porch. To resolve this issue I put a 2nd DDWRT device (running as a wireless access point) on the first floor, but unfortunately it has no battery backup.
About a year ago, I decided to change my strategy. I ditched the 2nd device, turned off wireless on the router itself, and bought myself a Ubiquiti wireless access point. This solves a lot of issues 1) Wireless is now one less feature I need to concern myself with on a router 2) It's reliability has been impeccable. In 1 year, it has been rock solid, not requiring a single reset, and it's worked flawlessly (and performed well) with every device I connected it to 3) It's designed to use power over ethernet. It's power supply is plugged in to the UPS in the basement, then the ethernet is patched between the powersupply and my patch panel and through the regular house networking. 4) It looks really nice, so I can actually put it in a very central place in the house without it looking ugly. And at this location, the one device provides exceptional coverage for my entire house and the front/back yard.
I agree. Anything I borrow from there I link right back. But not just for the reason you suggest. It's not uncommon to see topics on stackoverflow where an answer was marked as the accepted answer, then years later either the original answer stops working (due to a library or browser change), or a better answer comes along because someone noticed an obscure bug or a better solution is now feasible. If I (or someone else) later encounters a bug in that code, it's best to know where it came from so you can go back, check the comments, and see if there's an update.
That solves problem #1, where the Nest fails to turn on. Is there a solution for the opposite issue, where the unit fails to turn off and continues to run indefinitely? Would the solution be to take a 2nd analog thermostat, wire it in series with the nest, and have it set to the upper bound? So 3 thermostats in total? When the the Nest is set to heat the house to 70 degrees, you've got backup thermostat #1 wired in parallel and set to heat the house to 55 degrees, and you have backup thermostat #2 wired in series and set to heat the house to 85 degrees. That will allow the nest to wander between 55 and 85 before one of the failsafes kicks in.
Does that all make sense? Christ...3 themostats just to make sure the thing does its job properly?
Think about it....from the description it sounds like they are essentially archived based on time of upload. So when 5 years rolls around, guess where everybody's 5 year old photos are going to be: all on the same batch of blurays. So when 5 years approaches, they pre-copy those blurays back into online storage. After 3 months or whatever, those photos get purged from online storage and the old blurays are once again the only copy.
It is misleading to sponsors to show ads to people who don't want to see ads, and who refuse to ever click on ads. This would be no more than wasting bandwidth and (where an amount is charged per impression rather than per click) is a dishonest collection of revenue.
Sorry, but it's not the slightest bit dishonest. Do you think advertisers are under some mistaken impression that there's a 1-to-1 correspondence between impressions and clicks? No, of course not. They know only a fraction click through, and they even know that only a fraction of those that click through end up buying their product. But that's not a problem, because it's all built into their pricing model. That's why targeted advertising cost more per impression/click than general ads, and why the better targeted it is, the more it costs per impression/click. That's also why the revenue received by the websites showing the advertising has dropped over the years, as adblocking became more common and per-impression rates have plummeted and/or been switch to per-click payouts.
So what do you do if the residents decide not to go buy water, or can't afford it? Let them drink the contaminated water, I guess? Well, even if that is a bit heartless, OK...lets go with that "solution". So do we also condemn the 4 year old kids to drinking that water too, or are they supposed to get off their 4 year old asses, get a job, and go buy some safe bottled water on their own, since their parents can't or won't do it for them?
Nav Canada first detected a problem on 1 July 2014 when controllers noticed a 787 appearing to deviate up to 38nm (70km) from its planned track. The controllers alerted the crew by radio, but the pilots insisted their instruments showed they were still on course. Suddenly, however, the 787 “was observed jumping back to the flight plan route” on the controller’s screens, according to ICAO documents.
I'm sorry, but if a plane is reporting that it is 70km from where it actually is, that's no small deviation. That deviation is more than 10 times the required flight separation. It may not pose a safety hazard once controllers already know they have to fall back to the older system. But before this was discovered? That's a HUGE safety hazard. The only reason they can get away with claiming it wasn't a safety hazard was because they lucked out and the system only screwed up when there were no other planes around

In the US, three phase power comes into a residential neighborhood or a large building (apartment complex, industrial site, etc.) and typically two of the three are distributed to individual residences -- giving you your regular mains and a high-voltage for a dryer and/or stove. The phases are rotated between the different residences -- so one unit gets A and B, the next B and C, the next C and A, the next A and B, etc.
I don't know much about how power is distributed, but the way you explain it doesn't sound exactly right to me. Homes get their power in the form of a 2-phase 120v system where the phases are 180 degrees apart. The two 120v circuits are split between the two phases. Any 240 volt appliances bridge the two 120v phases to generate the 240v needed.
The way you explain it, the power in homes would be 120 degrees apart, not 180 degrees, thus you wouldn't be able to generate the required 240 volts. What am I missing here? Do they do some sort of phase adjustment in the neighborhood? I was under the impression that wasn't a minor thing to do.
I hate to say it, but they already have a "Made for iPhone" program where there are special chips the iDevices are looking for, and if they don't find it they will complain the accessory may not work properly:
Last I heard it never went past fear mongering but was still annoying. I can't remember if there was a way to disable it or not but I'm sure if so it was on by default.
That's nothing new. It's been around for a long time. I had a 2nd gen ipod touch. Apple wanted like $50 for their composite A/V cable (with the red/white/yellow connectors) so you could play video back on an old analog TV. Instead I went onto ebay and bought one for $3.50 that worked perfectly. Or at least it did work perfectly, until IOS 4.0 (I think that was the version, but maybe it was 3.0) was released. Then whenever the cable was connected, it would pop up that error message. You could still use the audio out on the cable, but the video portion was useless (I don't remember if it completely stopped working or was just useless because it showed the error message on your TV). The only way to get video out was to buy a new ridiculously priced official cable that had their DRM chip inside.
I don't know if Costco has changed the way they do it recently, but when I tried to use Costco's car service 5 years ago it certainly wasn't that simple. I went to Costco to check the price, and they told me I'd have to contact the Toyota dealer to get the price (and there was only 1 participating Toyota dealer in the area). I called the dealer up, and they absolutely refused to provide any pricing info over the phone. They wanted me to drive there...20 miles away. Let's just say I was less than impressed by usefulness of the service.
Okay, didn't know that about glass, and still find it suspicious - if that were the case then you wouldn't need IR filters in cameras, etc, and would probably have proven problematic for Herschel's accidental accidental discovery of infrared. But okay, maybe for far infrared you'd need a special prism.
No need to remain suspicious. Simply look it up yourself. That's what google is for right? But I'll do it for you anyway.
Visible light is in the 390-700 nm wavelength. Glass is transparent mostly in the 350 to 2500nm range, and is almost completely opaque outside of the 250 to 4000nm range CO2 absorbsion occurs at 4257, 7204, 14992nm (more commonly notated as 667, 1388, and 2349 cm-1, in case you want to search to do your own verification)
So you can see there is a ton of IR in the 700-2500 range that glass is nearly completely transparent to. That's why you can have IR cameras. But CO2 is WAY out of range.
No, he's right. Higher polling frequency plus intelligence is technically the best solution. If you decrease polling frequency, you become more susceptible to losing distance around curves and right angle turns. Instead, the best solution is to poll continuously (or as continuously as is practical for computational and battery needs).
Assuming you travel in a straight line, then all of those errors should be randomly distributed to both sides of your actual line of travel. You then go from the starting point and assume you traveled in a straight line to the next point. You then go in a loop where every iteration, you bump up the assumed end point of your straight line by one additional point. Each time, you calculate how far off you are from the best fit line.
As you go further and further, your fit for the line should get better and better. At some point, you will eventually notice that you start to diverge from the best fit line...the points in between your assumed start and end point will start to fall more and more to one side of the line. At this point, you can start to realize that you've actually passed the end point of that straight line travel. You back up a few points until you get back to a good distribution. Then you mark that as the end point of your straight line, and then repeat the process from there.
On the other hand, assume you are travelling on a curve. With a high enough sampling frequency, this same process should be able to determine that right from the start, the line is becoming less and less fit, and realize that the straight line path needs to be broken up into smaller segments.
The algorithm isn't going to be great for capturing a zig zag path or lots of small alternating curves, but it's not going to be any worse for those situations than polling less frequently.
It's bullshit because why use ultrasound? I'm sure the sound of a commercial playing can be recognized from the commercial itself, just like Shazam can recognize a song. And to make things easier just embed a very recognizable sound in the commercial that is not annoying but is sure to be picked up and recognized.
Yes, exctly. I wish I had mod points. The premise of this is so stupid. If the app already has access to the microphone, then just listen to the commercial itself. The ultrasonic part is going to be so hit or miss. It's not a sound that the broadcast and TV is explicitly trying to reproduce, so it's going to be EXTREMELY hit or miss. Just think about the sound the TV is actually trying to intentionally reproduce, and how much it varies depending on different factors. 1) audio compression method 2) volume 3) type of speakers 4) the acoustics of the tv/cabinet the speakers are enclosed in 5) distortion characteristics of the amplifier circuitry 6) the shape and furnishings of the room 7) your position within the room
and probably more that I'm not thinking of. Then add in for your phone detecting that normal range of sound
8) materials between the speaker and the microphone (is the phone in your pocket? is your hand obscuring the microphone?) 9) other sounds within the room, airplanes flying by, etc 10) The characteristics of the microphone within the phone
Then you go to ultrasonic...a range that hasn't been explicitly designed for, and every one of those above factors gets magnified.
And to make it all even stupider...they think this is a way to link multiple devices together by virtue of them hearing the same ad? LOL...if they are able to overcome all of the above obstacles and actually detect the sound from 2 different devices, how are they going to know these aren't 2 entirely different people in different houses watching the same TV channel? I've got a much better method of correlating devices...by IP address. Most people have their phones set to connect to wifi in their house, and most people will have all devices NATed to a single IP.
I suppose it all might someday be possible to pull off this ultrasonic stuff. It's also possible I'll some day be able to travel to china by means of digging my way there. But just as it's always going to be quicker/easier for me to just take a plane to China, I'm pretty sure the commercial detection and device correlation will always be easier to accomplish with methods other than the ultrasound method.
If your account is getting charged $0.25 / debit then either you don't live in the US or you need to get a new bank. In the US the fee used to be about $0.40 but a few years ago Congress capped it at $0.21 and I've never heard of a bank making you pay part of that fee (though some merchants will). In fact some banks will even split that fee with you. If you get a Discover checking account, for example, they will give you $0.10 cash back / debit

Even an old analog TV could give you a 1.44gb photo, when you consider slight variations in subpixel noise (remember...he said photo, not screenshot).
Now, on the other hand...the camera that takes 1.44gb photos is something that I might actually be interested in.

Nav Canada first detected a problem on 1 July 2014 when controllers noticed a 787 appearing to deviate up to 38nm (70km) from its planned track. The controllers alerted the crew by radio, but the pilots insisted their instruments showed they were still on course. Suddenly, however, the 787 “was observed jumping back to the flight plan route” on the controller’s screens, according to ICAO documents.
I'm sorry, but if a plane is reporting that it is 70km from where it actually is, that's no small deviation. That deviation is more than 10 times the required flight separation. It may not pose a safety hazard once controllers already know they have to fall back to the older system. But before this was discovered? That's a HUGE safety hazard. The only reason they can get away with claiming it wasn't a safety hazard was because they lucked out and the system only screwed up when there were no other planes around

In the US, three phase power comes into a residential neighborhood or a large building (apartment complex, industrial site, etc.) and typically two of the three are distributed to individual residences -- giving you your regular mains and a high-voltage for a dryer and/or stove. The phases are rotated between the different residences -- so one unit gets A and B, the next B and C, the next C and A, the next A and B, etc.
I don't know much about how power is distributed, but the way you explain it doesn't sound exactly right to me. Homes get their power in the form of a 2-phase 120v system where the phases are 180 degrees apart. The two 120v circuits are split between the two phases. Any 240 volt appliances bridge the two 120v phases to generate the 240v needed.
The way you explain it, the power in homes would be 120 degrees apart, not 180 degrees, thus you wouldn't be able to generate the required 240 volts. What am I missing here? Do they do some sort of phase adjustment in the neighborhood? I was under the impression that wasn't a minor thing to do.
Hanged. You hanged yourself in a barn in 1272.
Simple Freudian slip. He was likely preoccupied thinking about how he'll finally be able to hung himself in 2016 with his DIY CRISPR
I hate to say it, but they already have a "Made for iPhone" program where there are special chips the iDevices are looking for, and if they don't find it they will complain the accessory may not work properly:

Last I heard it never went past fear mongering but was still annoying. I can't remember if there was a way to disable it or not but I'm sure if so it was on by default.
That's nothing new. It's been around for a long time. I had a 2nd gen ipod touch. Apple wanted like $50 for their composite A/V cable (with the red/white/yellow connectors) so you could play video back on an old analog TV. Instead I went onto ebay and bought one for $3.50 that worked perfectly. Or at least it did work perfectly, until IOS 4.0 (I think that was the version, but maybe it was 3.0) was released. Then whenever the cable was connected, it would pop up that error message. You could still use the audio out on the cable, but the video portion was useless (I don't remember if it completely stopped working or was just useless because it showed the error message on your TV). The only way to get video out was to buy a new ridiculously priced official cable that had their DRM chip inside.
I don't know if Costco has changed the way they do it recently, but when I tried to use Costco's car service 5 years ago it certainly wasn't that simple. I went to Costco to check the price, and they told me I'd have to contact the Toyota dealer to get the price (and there was only 1 participating Toyota dealer in the area). I called the dealer up, and they absolutely refused to provide any pricing info over the phone. They wanted me to drive there...20 miles away. Let's just say I was less than impressed by usefulness of the service.
Okay, didn't know that about glass, and still find it suspicious - if that were the case then you wouldn't need IR filters in cameras, etc, and would probably have proven problematic for Herschel's accidental accidental discovery of infrared. But okay, maybe for far infrared you'd need a special prism.
No need to remain suspicious. Simply look it up yourself. That's what google is for right? But I'll do it for you anyway.
Visible light is in the 390-700 nm wavelength.
Glass is transparent mostly in the 350 to 2500nm range, and is almost completely opaque outside of the 250 to 4000nm range
CO2 absorbsion occurs at 4257, 7204, 14992nm (more commonly notated as 667, 1388, and 2349 cm-1, in case you want to search to do your own verification)
So you can see there is a ton of IR in the 700-2500 range that glass is nearly completely transparent to. That's why you can have IR cameras. But CO2 is WAY out of range.
No, he's right. Higher polling frequency plus intelligence is technically the best solution. If you decrease polling frequency, you become more susceptible to losing distance around curves and right angle turns. Instead, the best solution is to poll continuously (or as continuously as is practical for computational and battery needs).
Assuming you travel in a straight line, then all of those errors should be randomly distributed to both sides of your actual line of travel. You then go from the starting point and assume you traveled in a straight line to the next point. You then go in a loop where every iteration, you bump up the assumed end point of your straight line by one additional point. Each time, you calculate how far off you are from the best fit line.
As you go further and further, your fit for the line should get better and better. At some point, you will eventually notice that you start to diverge from the best fit line...the points in between your assumed start and end point will start to fall more and more to one side of the line. At this point, you can start to realize that you've actually passed the end point of that straight line travel. You back up a few points until you get back to a good distribution. Then you mark that as the end point of your straight line, and then repeat the process from there.
On the other hand, assume you are travelling on a curve. With a high enough sampling frequency, this same process should be able to determine that right from the start, the line is becoming less and less fit, and realize that the straight line path needs to be broken up into smaller segments.
The algorithm isn't going to be great for capturing a zig zag path or lots of small alternating curves, but it's not going to be any worse for those situations than polling less frequently.
It's bullshit because why use ultrasound? I'm sure the sound of a commercial playing can be recognized from the commercial itself, just like Shazam can recognize a song. And to make things easier just embed a very recognizable sound in the commercial that is not annoying but is sure to be picked up and recognized.
Yes, exctly. I wish I had mod points. The premise of this is so stupid. If the app already has access to the microphone, then just listen to the commercial itself. The ultrasonic part is going to be so hit or miss. It's not a sound that the broadcast and TV is explicitly trying to reproduce, so it's going to be EXTREMELY hit or miss. Just think about the sound the TV is actually trying to intentionally reproduce, and how much it varies depending on different factors.
1) audio compression method
2) volume
3) type of speakers
4) the acoustics of the tv/cabinet the speakers are enclosed in
5) distortion characteristics of the amplifier circuitry
6) the shape and furnishings of the room
7) your position within the room
and probably more that I'm not thinking of. Then add in for your phone detecting that normal range of sound
8) materials between the speaker and the microphone (is the phone in your pocket? is your hand obscuring the microphone?)
9) other sounds within the room, airplanes flying by, etc
10) The characteristics of the microphone within the phone
Then you go to ultrasonic...a range that hasn't been explicitly designed for, and every one of those above factors gets magnified.
And to make it all even stupider...they think this is a way to link multiple devices together by virtue of them hearing the same ad? LOL...if they are able to overcome all of the above obstacles and actually detect the sound from 2 different devices, how are they going to know these aren't 2 entirely different people in different houses watching the same TV channel? I've got a much better method of correlating devices...by IP address. Most people have their phones set to connect to wifi in their house, and most people will have all devices NATed to a single IP.
I suppose it all might someday be possible to pull off this ultrasonic stuff. It's also possible I'll some day be able to travel to china by means of digging my way there. But just as it's always going to be quicker/easier for me to just take a plane to China, I'm pretty sure the commercial detection and device correlation will always be easier to accomplish with methods other than the ultrasound method.
If your account is getting charged $0.25 / debit then either you don't live in the US or you need to get a new bank. In the US the fee used to be about $0.40 but a few years ago Congress capped it at $0.21 and I've never heard of a bank making you pay part of that fee (though some merchants will). In fact some banks will even split that fee with you. If you get a Discover checking account, for example, they will give you $0.10 cash back / debit
