daten··on London Met Police lab uses "electrical network frequency analysis" (ENF)
I had the same response, but then I thought "wait, I don't do any covert and sketchy surveillance, this doesn't affect me".

Can you think of any privacy concerns with this technology?

daten··on London Met Police lab uses "electrical network frequency analysis" (ENF)
Here's a white-paper with more detail about the technology.

http://www.diamondcut.com/Downloads/AppNote4DiamondCut.pdf

The author describes a case-work example where he compares an analyzed audio file to ENF data from the power company (?) about the building and can prove it wasn't recorded on the claimed date and there were multiple deletions.

daten··on Gmail has become unusably slow
Do you really expect GMail to provide personal customer service to its ~176m [1] non-paying users?

Don't mistake non-paying for no-profit. Those users don't pay cash but they do give google lots of personal data and ad-clicks that makes google money. I would personally rather pay a fee and keep my data private and not see ads.

If google loses "non-paying" customers because of performance issues or outages that they don't know about because there's no effective way to contact them, they also lose money just like a company with paying customers.

daten··on Why I Switched from iPhone to Android
get over it. some people like consistent ui controls between apps (hello, HIG) for a less confusing user experience. and really folks, flash has never been allowed to be in the store, yet somehow they've built a 200,000+ app ecosystem worth > $4B in revenues.

"get over it"? why?

Can I be the judge of what kind of UI controls I like instead of Apple deciding for me? This hasn't be a problem with any Windows or Linux app I've ever used or any webpage I've ever visited. I guess I don't confuse easily.

And without those same app store policies holding them back, how long do you think it will be before Android passes Apple's ecosystem?

200,000+ is a lot of apps, but how many of them are "fart apps" or something equally as useful?

The $4B in revenue also sounds like an impressive number, how much of that money is because users had to pay for apps to make up for the lack of flash? And why does it matter to me how much money they've made? Isn't that part of the problem? At the end of the day the app store doesn't exist to serve users, it exists to make Apple as much money as possible, this motivates them to maintain as much control over it as possible no matter what the cost to users or developers is.

daten··on Why I Switched from iPhone to Android
The reasons the author states are all why I'm not getting an iPhone, primary Apple's unwelcome control over the app store.

I'm eager to "jump on the Android bandwagon" but I have to figure out how to deal with the ETF on my current featureless Motorola phone with Sprint. Apparently replacing a broken phone resets your contract date.

daten··on I've Changed My Mind About The iPad
The draconian app store policies alone are reason enough for me. I wouldn't try to downplay that.

Other limitations Apple puts on their devices come in second. I'm a very technical person. I would be happier having another gadget with Linux on it.

daten··on I've Changed My Mind About The iPad
I'm not trying to troll, I just have an ongoing concern when I read articles like this.

Another way to look at it is, I've been convinced by marketing and countless articles on HN telling me how amazing this new gadget is that I went and bought one.

Now I need to find a place it fits in my life and convince myself it's something I didn't know I needed and that I didn't waste my money.

I've only owned it for a week but I'm sure that a year from now I'll still love it because it's a great product, not because it's new and shiny.

daten··on Your computer room will overheat next weekend
That's how it works in my office building. It also kicks off at 7PM on weekdays. It may not be completely off, but you can hear it blowing all day and at 7PM there's a loud THUMP in the vents and no sound after that.

Not a problem, our server room has independent cooling that takes the heat to a unit on the roof. It might have to work a little harder on long weekends but we keep track of our heat budget and this isn't a problem.

daten··on A look at the wireless traffic of MIT students
I thought it sums up the article pretty well. I was expecting much more based on the title.

A better title: "Amateur high-level wireless traffic analysis of 21 consenting students during a 45 minute class"

daten··on Retweeting links and replying “cool stuff ” is not a discussion
I disagree. There may be plenty of things to complain about with facebook, but I still find it plenty useful to stay in touch with friends, family and acquaintances. We plan events, share photos, keep current with what's happening in each others lives and occasionally have long discussions on specific topics. For me it works exactly the way it's supposed to and it's easy to ignore the ads on the side of the page.

I worry that the real "hype" right now is buying into the recent anti-facebook trend.

daten··on I’m graduating with a CS degree but I don’t feel like I know how to program.
I also like this page for evaluating where you might stack up against other candidates.

daten··on Future of Flash
That's my experience with any recent ATI card in Linux. Flash doesn't have to be involved. High resolution or full-screen video with a quad-core AMD Phenom and 8GB of ram results in dropped frames and tearing.

I fixed it by switching back to NVIDIA.

daten··on FBI Gets Evidence in Student Webcam Scandal
"someone who covertly installs photographic equipment in the bedrooms of minors should get at least 1000."

Why?

They should spend the rest of their life in jail for invading someone's privacy? Is this to protect society or for revenge? Do you feel it's not possible to teach the person why you think their actions were wrong and release them back into society so they can continue to contribute positive things? What if there really was no ill-intent? What if the software was legitimately installed only for the purpose of recovering stolen property and the images that were archived were done so only for that purpose or accidently? Does the person responsible only have to serve a life sentence if they had voyeuristic motivations?

daten··on "Malamanteau", a self-powered notability?
I was disappointed to learn that the history of deleted wikipedia pages is hidden from public view.
daten··on How did Facebook guess my email address?
I know facebook tracks how users browse their site and which profiles they look at, how often and how long (from articles facebook staff were interviewed in). I wonder if they have starting using that data to recommend friends? If someone is searching for a particular person frequently enough, or regularly visiting the public parts of their profile, they probably know each other.

I'm not saying it's appropriate.

daten··on What iPads Did To My Family
I understand why it's fun to play with a new (limited) device. I have an ipod touch. But I worry when people rush to buy $500 devices without being able to articulate why they need it. It sounds like good marketing and impulse shopping. I'm very curious to see how this plays out in the long run.
daten··on The People Who Support Linux. Do You?
I support Linux by using the OS (the kernel /and/ open source applications) every day in a business environment, discovering bugs and submitting bug reports and patches to improve the software.

I feel like this article is just a fund-raising advertisement for the "Linux Foundation". I wonder what's more valuable to the community, money I give to one organization or time and skills I use to benefit many different applications.

daten··on Why I went without hot water for a year
I assume this is rare, but the lack of sanitization in this case paralysed a 22 year old woman.

""" Then her diarrhea turned bloody. Her kidneys shut down. Seizures knocked her unconscious. The convulsions grew so relentless that doctors had to put her in a coma for nine weeks. When she emerged, she could no longer walk. The affliction had ravaged her nervous system and left her paralyzed.

Ms. Smith, 22, was found to have a severe form of food-borne illness caused by E. coli, which Minnesota officials traced to the hamburger that her mother had grilled for their Sunday dinner in early fall 2007. """

daten··on Why I went without hot water for a year
I can't speak for him, but I shower once a day. I enjoy feeling clean and not smelling. I also appreciate when others do the same.

The whole experiment seams to be about his ego, I wish he tried to gain more insight into other reasons people chose to stay clean enough to not offend their peers with their smell instead of just concluding:

"I felt myself standing apart from the sheep-like masses who had been led to confuse their wants and needs."

daten··on McAfee quarantines svchost.exe on millions of WinXP machines worldwide
With fake SSL certificates signed by "real" CAs, cross-site scripting and other advances in phishing attacks, just educating users may not be as effective as it used to be. Malware is quickly becoming advanced enough that even trained technical users may be fooled. Many attacks don't require user interaction. AV products may be slow to respond and signature matching won't catch everything, but if it catches half of what shows up on corporate networks it can still save a lot of time and money.
daten··on XKCD "Hell" implemented in flash
My observations of the game mechanics.

0. Once a piece touches another piece, you lose control of it.

1. The weight of one piece can affect the balance of others.

2. If you hold a piece against the side walls, it will stop descending.

3. If you move a piece into the wall and then immediately away from it, you can put it into a slow spin while still being able to flip the piece.

4. You can control the descent speed by tapping the down arrow. After each acceleration, the downward velocity resets when you stop accelerating. If you reduce the speed with which the pieces collide, the already stable pieces will not bounce as much.

5. Getting something really close to a complete horizontal row does not cause the row to disappear. I have not yet achieved an arguably perfect horizontal row.

daten··on MSNBC Blocking Searches for "Wikileaks"
It might matter how recently you posted them. I don't know exactly how facebook works but I'm assuming they have multiple servers that changes have to get synced to. Sometimes it can take 30 minutes after I post something before it will reliably show up. You can refresh once and see it, refresh again and it will be gone.
daten··on Wikileaks gun camera video of civilians shot in Baghdad 07/12/07
Are you saying you're not responsible for the lives you take if the organization that trained you had better advertisement funding?
daten··on Am I the Only One Who Uses a Text Editor to Edit Files?
Control-Option-Command-8 switches the display to greyscale, then inverts it (in other words, black text on white becomes white text on black).
daten··on Find your birthday (or any other number) in pi ...
Weird. If I "See 10 digits starting at position 186,557,264", the result is: 8912345678

But if I search for that result, it doesn't find it.

If I search for 12345678 it finds it and you can see 89 before it. Why can't I search for that number?

daten··on I want privacy because I break the law
Hopefully you get some jurors who are familiar with Jury Nullification. Otherwise the instructions from the judge and persuasion by the prosecutor might convince them they have no choice but to follow the letter of the law.
daten··on TSA Security Directive SD-1544–09-06
Do those doors still have shades if they're never allowed to be closed?
daten··on TSA Security Directive SD-1544–09-06
The "terrorists" aren't the reason he prefers the train. Terrorist attacks on both are so rare that they're not a real reason to prefer one over the other. However the overly invasive, rude and ineffective airport security is a strong reason not to fly when there's an alternative available. For some reason the trains, malls, schools, libraries, churches and stadiums around where I live aren't getting blown up by terrorists and they have little or no security at all.
daten··on Eric Schmidt: "If you have something [to hide], maybe you shouldn't be doing it"
I agree. This is an important thing to realize. It's also not just analytics. Every site that links to advertisements controlled by google or one of the many advertising companies they've acquired can also be used to correlate data about you. I started worrying more when they bought doubleclick.net. I wonder if that same google opt-out cookie works for those sites? What if you're concerned about your privacy enough to clear your cache and cookies every time you close your browser? Google is in a stronger position to track more of what you do on the net than many people may realize.
