bugnuts writes "Nearly all modern DSLRs use a Bayer filter to determine colors, which filters red, two greens, and a blue for each block of 4 pixels. As a result of the filtering, the pixels don't receive all the light and the pixel values must be multiplied by predetermined values (which also multiplies the noise) to normalize the differences. Panasonic developed a novel method of "filtering" which splits the light so the photons are not absorbed, but redirected to the appropriate pixel. As a result, about twice the light reaches the sensor and almost no light is lost. Instead of RGGB, each block of 4 pixels receives Cyan, White + Red, White + Blue, and Yellow, and the RGB values can be interpolated." Link to Original Source top
bugnuts writes "Shortly after announcing a 120 megapixel sensor which might be the world's densest CMOS sensor, Canon announced the world's largest CMOS sensor measuring 202 x 205mm. Canon has developed a dense 50 megapixel sensor in 2007, but it was never put into a camera. A larger sensor, however, is starting the rumor-mill about a large format or nighttime video camera in the works. The sensor makes possible the image capture in one one-hundredth the amount of light required by a 35 mm full-frame CMOS sensor, facilitating the shooting of 60 frame-per-second video with a mere 0.3 lux of illumination. Based on the 5Dm2 H1 ISO of 12,800 that means the new sensor has as much light-gathering as an ISO around 819,200!" Link to Original Source top
bugnuts writes "Following a rather cool spring in North America, another attack on the scientific consensus that humans are largely responsible for climate change has surfaced. A criminal hacker on a UK system leaked apparent emails from climate scientists which imply some sort of deception was going on. Some of the emails are clearly scientific in nature such as, "The fact is that we can't account for the lack of warming at the moment and it is a travesty that we can't. The CERES data published in the August BAMS 09 supplement on 2008 shows there should be even more warming: but the data are surely wrong. Our observing system is inadequate", but which will be grabbed with both fists by the climate change deniers and other zealots. More troubling, however, are excerpts such as "Can you delete any e-mails you may have had with Keith re AR4? Keith will do likewise."
These emails are certainly taken out of context, whether they are legitimate or fraudulent, which adds to the confusion." top
bugnuts writes "Blizzard announced a policy change to Addons for the popular game World of Warcraft which asserts requirements on UI programmers, such as charging for the program, obfuscation, soliciting donations, etc. Addons are voluntarily-installed UI programs that add functionality to the game, programmed in Lua, which can do various tasks that hook into the WoW engine.
The new policy has some obvious requirements such as not loading the servers or spamming users, and it looks like an attempt to make things more accessible and free for the end user. But unlike FOSS, it adds other requirements that assert control over these independently coded programs, such as distribution and fees.
Blizzard can already control the ultimate functionality of Addons by changing the hooks into the WoW engine. They have exercised this ability in the past, e.g. to disable addons that automate movement and "one-button" combat. Should they be able to make demands on independent programmers' copyrighted works, such as download fees or advertising, who are not under contract to code for Blizzard? Is this like Microsoft asserting control over what programmers may code for Windows?" top
bugnuts writes "The Warhammer Online: Age of Reckoning MMO servers will open to public retail Thursday morning at midnight. The servers have already been open for two days for customers that pre-ordered the game, and four days for those that pre-ordered the Collector's Edition. Those subscribers were given a code, which enabled the open beta client to run on the retail servers early.
bugnuts writes "At airports everywhere, they say "No Jokes", and take even off-color non-joke comparisons as seriously as a tornado. Thompson's latest letter, hand delivered to Chief Judge Federico Moreno, contained a comparison of his treatment to Al Queda which was not taken lightly. Thompson wrote:
We find yesterday that enemy combatants at Guantanamo are to get more due process from federal judges than what I am to have. I guess my "mistake" was not killing 3000 people to make my point...
Marshals visited Thompson, probably to determine if it was a credible threat, which invoked an inevitable long-winded response." top
bugnuts writes "A ruling that remote DVRs are not the same as personal DVRs may have some farther-reaching consequences on the Betamax defense of "timeshifting". Cablevision wanted to offer the ability to record programs on their own hardware at the user's request, which the user could playback later. Although it sounds innocuous (simply duplicating the DVR capabilities), it constitutes a service — which therefore does not get the protections of the Betamax case."
I took up the fight to recover the $550 data bill I received while on travel for 10 days, while my iphone dutifully and silently received lots of email and spam and so on every 30 minutes.
Initially, ATT offerred a $150 courtesy credit, which I took but mentioned that I'd be calling them back. I did so when they threatened to cut off my service. My terms were actually forgiving. While on travel, it was possible to get wifi for $15/day, so if I had purchased it there it would've cost $150. That is what I offered to pay ATT for the data charges. An argument with the customer representative ensued, but I did not back down. My point was simple: I couldn't turn it off without losing functionality unrelated to the data service. Forcing me to turn the phone off completely means I lose the iPod features, and leaving it in airplane mode means I lose the wifi and bluetooth features.
The customer service rep filed a dispute on my behalf, but I had little confidence she would forward my complaint and reasons (since she had been arguing against them with me for 10 minutes). However, she told me what was in the report and it included what I had stated.
I'm happy to report that ATT reversed all the data charges from what I can tell. I may have been charged interest for late payment, but I'm not even certain of that until I see the full itemized bill. It appears they didn't take my offer of paying $150.
My recommendation if this happens to someone else is to remember that this is a financial issue... do not lose your cool. There's always someone higher you can take this to, even if that means a judge. Like an insurance adjuster, the customer service rep is not your friend and will do everything possible to screw you, but it's not personal. Don't take offense or be offensive, because in my case this person actually forwarded my complaint to a higher department. You don't want this person emotionally involved enough to want you to lose. Have your defense in mind, and always fall back on it if you are being dragged into a different argument... that may even involve simply repeating yourself every few minutes. If it's clear you are going nowhere, ask to escalate it up the chain and ask if you need to send a written request. Good luck.
Several people have written tomes about the technological advancements and "revolution" the iPhone will bring to cellphones, both in software and hardware. Many have written tomes of the evils of it, and how they are in bed with AT&T, known to ignore your privacy. As an early adopter, I was expecting some shortcomings. What I came across, however, was a hidden landmine that will cost me hundreds of dollars paid to one of my least-favorite companies, ATT.
For those that don't know, the iphone will automatically search for wifi, and piggy-back onto those networks if allowed. If it doesn't find any, or if it can't connect for whatever reason, it falls back onto the slower cellular Edge network. This seems like a very good default and it works really well for most cases. Browsing on the iphone still amazes me on the clarity and fact that if I'm ever bored, I can just fire up a browser no matter where I am. It even downloads my email locally, and pulses when I receive a new message. You can be perpetually connected to your websites and email.
It is a geek's dream, and I'm living the dream.
Recently, however, this dream turned into a nightmare. I was on travel in the Caribbean. As soon as I powered up my iphone and took it off of the airplane mode, the iphone dutifully retrieved my email automatically incurring roaming data charges. This is, of course, despite having unlimited data in my contract with ATT. This was also happening unbeknownst to me, and there was nothing I could do about this even if I had known, except turn the radio completely off! Even if I purchased local wifi use or used a free hotspot, if it ever lost wifi connectivity it would fall back on the Edge network and incur roaming charges. Turning off the radio would prevent roaming, but would also disable use of local wifi and bluetooth. There is simply no way to tell a registered iphone to never roam without disabling the radio completely.
I discovered this only after I received a $550 bill for roaming data charges. Not once did I make an actual phone call, although I did intentionally send a couple photos I took. Most of this data transfer was from things like the phone automatically downloading my email (which I subsequently read), a little bit of web browsing, and even checking the local weather report. After a somewhat shocked call to ATT, they offered to forgive $150 of it which I accepted, but I did so without agreeing that I wouldn't pursue this further. I'm hoping this article will help prevent others from having such a surprise and financial burden.
[added 13-sep] My case of ignorance coupled with Apple's failure to program an anti-roaming feature is notunique. Rules lawyers argue that the defaults for email had been changed, or that "the phone wasn't off". But what use is a phone that has to be disabled in order to prevent racking up roaming charges? I would have still gotten roaming charges had I used the local wifi. That's because the wifi antenna is not particularly sensitive, and it's extremely unlikely it wouldn't fall back on Edge at some point. And heaven forbid my local wifi drops while I'm not actively using the phone, or once again, it'll do exactly what it's programmed to do: fall back on the Edge network and continue downloading. Works great in the US, but is a horrible default outside the local network boundaries.
Although I'm very disappointed and quite annoyed at the roaming fees, here is a quick rundown on the pros and cons of the iphone from my perspective. More importantly, it is weighted with the perceived importance. Some big "problems" that iphone detractors proclaim really are not very significant in practice, and there are several problems I've encountered that I never see stated.
I purchased my iphone knowing it would be hacked/opened at some point in the short future. It is intuitive and made for the masses, but also a perfect device for hackers - a hand-held Unix device with a radio and camera. Potentially completely programmable. Multiple inputs, bright and colorful display, a glass screen, and damn sexy, too.
The reasons I bought an iphone are largely self-explanatory:
Multiple touchscreen inputs (probably the first COTS handheld device with this).
Excellent hardware and looks (no moving parts, bright glass screen, responsive, built tough, and damn sexy).
Geek factor - runs Unix (which was destined to be hacked).
Full web browser. (Except for flash, which I don't use anyway. Or Java, but again, I'm a luddite in some ways.)
2 Megapixel camera has about double the pixels of older phonecams.
Video playback with sound.
Wifi and data.
In addition, here are some great features I discovered after owning the iphone:
Icebreaker. It's like carrying around a cute puppy - people love it.
UI: scrolling voicemail allows you to listen out of order. Surprisingly useful.
UI: scrolling through ipod songs and videos makes it really easy to find the song you want.
UI: google maps is great fun, and quite useful.
Hardware is even better than I thought it would be. The screen is nothing short of amazing, and the touchscreen works great.
Here are the problems, with my comments on the significance:
Sometimes hangs/crashes, needs a full restart. This bit me a few times, especially at first. The system crashed continually, I received no voice messages or SMS messages, and it was very frustrating. A simple reboot (holding down the power key for 6 sec) solved all the problems. Although a BIG issue, I solved it by accident. And this is happening to a lot of people.
Sweaty fingers don't work so well. Anyone with sweaty hands knows how difficult most laptop touchpads can be -- this is not quite as bad, but noticable. Also, the smudges on the screen are not an issue like many people thought it would be. My glass screen is still pristine, and just takes a simple wipe on the pant leg to clean.
No "thumb" on the webpage. Scrolling to the bottom of a large webpage is simply stupid. Am I missing something?
Where's the tilde? Finding some of the special characters on the typewriter took some work. (Hint: you have to hit shift after going to the symbols page.)
No addons to Safari. This concerns me, but I suspect this will be solved soon enough. I can't wait for someone to port firefox, though.
No Flash in Safari. This really doesn't bother me. Flash has very little user-control, except through addons to prevent it from running, and I definitely don't want it installed if I can't disable it somehow. In the rare cases I allow it on my normal browser, I would miss it on the phone. But for the most part, I see flash as an annoyance, used by advertisers and idiots to ram content down your throat. For the most part, flash makes my browsing less enjoyable, not more, so I don't miss this at all. Besides, it'll be ported soon enough, I'm certain.
No flash on the camera, either. Despite having more pixels than most older phones, the camera is not really that high of quality, especially compared to some cellphones coming out today. It'll take great pictures in good indirect light. But if you put a bright spot anywhere, or take pictures in subdued lighting, your colors and pictures will be poor. Impressive in good conditions with good colors and clarity, but lack of any programmability of light sensitivity or zoom means you get mediocre pictures in all but perfect conditions. Also, the capture is a little slow (perhaps 1/2 second, which is enough to lose the perfect shot). Lastly, the shutter button is on the screen so it's more difficult to hold the phone in awkward positions to take photos (e.g. of yourself or over your head).
No video recording. For some people, this killed the iphone for them. This is not the case for me -- I don't really mind not having video. All current phone video is such poor quality that I question the ability as simply a useless bell and whistle. Use a real camera to make real videos.
Poor speakerphone. Rarely mentioned is the low volume of the speakerphone. Or for that matter, the low volume of the ringer, too. The tiny speaker just cannot belt out the sound. And this is annoying if you're trying to use the speakerphone while driving. Get a bluetooth headset which will work really well.
2G, not 3G radio. Apple could have used a more modern radio and a faster data network, but did not. They use the Edge network, which is a bit pokey, and the fact you can do full browsing makes it feel even slower... it downloads the pictures so webpages take much longer to load. But that's the price for the quality of the browser. I can live with this, but it is annoying.
No GPS. What was apple thinking? Integrate maps into it, but not tell you where you are? And how the heck can you save the current location as a bookmark in the maps, to look up later? IMHO, the intuitive interface loses a bit in the mapping software.
No 3rd party apps. Not an issue... they're coming whether Apple likes it or not! Already you can get screenshots of web pages, voice recording, arbitrary ringtones, etc. You can even ssh into your iphone, and *gasp* run apache on it. No, really.
Lack of "buttons" makes it difficult to type. Minor issue, and noticable when using the camera. Most of the time when you'd be fumbling around (like driving) you can use the "favorites" to make calls and not the keypad. The typewriter is easy to make typos, but the software works surprisingly well to correct errors and typos. Seriously, it's good. After playing with it a weekend, you'll be typing like a pro. Well, not a pro, but you can do 20-30 wpm which is plenty good enough for a handheld.
No voice dialing. I'd bet someone will be able to make an app to do this in the future. It's a big oversight by apple, but only a moderate problem.
Mono-only bluetooth. Not an issue for me, but could be for others who use bluetooth headphones to listen to music.
Incompatible with many ipod addons. This is a big issue which I think will affect many people. Not only do the ipod functions not send sound through the docking port (so most ipod speakers and car kits will not work), but the earphone jack is recessed which makes most minijack plugs incompatible.
Cannot set your own background image. This is false, but I see a lot of people claiming it. You can set a background image easily. You simply tell itunes to sync photos to a folder on your computer, and drop your background image into this folder. Then you can view it on the phone and set it as your background.
No Instant Messaging. I suspect this will be coming soon, through a 3rd party app. Someone will port gaim or write one. But then your battery life will probably go to hell.
Poor support for sending photos. No MMS support at all, and you cannot crop photos sent via email. A big oversight for a phone that is supposed to integrate such features.
Battery replacement requires mailing the phone in. To me, this is only a minor issue. The reason why it's minor is that I reap huge benefits from it. Because apple did not have to invest in packaging the battery and terminals, they could make the battery significantly larger. And I'm happy to lose my phone for a week, in order to have an extra hour or two the rest of the two-year expected battery life. It is a good tradeoff, although granted, could be an annoying one to some people.
There seems to be a lot of "cons" compared to the "pros". So, would I buy an iPhone knowing what I do now? The answer is still a solid "Yes".
