Agreed, except in the case of certain media industries which seem to command the government and police to carry out their orders.

4K Ultra HD Likely To Repeat the Failure of 3D Television

davegravy 4K in business (559 comments)

I'm not sure about 4k for home use, but I think it has applications in office environments.

The small company I work for (less than 50 ppl) just bought a 65" 4K TV for use in one of our meeting rooms for collaborative computer work. I tried outputting a desktop to a number of 1080p panels and the picture quality was quite shit (unless of course you stand far away to the point the panel seems too small and you can't read much).

I'm not sure why that is... 1080p computer monitors are fine, but for some reason it just doesn't translate to TVs.

At 4k, PC picture quality is acceptable - actually quite remarkable, and so we went this route. We just got the thing so time will tell how useful it is.

Egyptian Security Forces Storm Pro-Morsi Camps Leaving Nearly 100 Dead

davegravy Re:So Much for Democracy (381 comments)

You can't have a democracy and a precedent for simply removing elected leaders when you are not satisfied with the outcome.

I agreed at first.

But in theory such a system might be an improved one - if we can elect people based on their platforms and then axe them when their platform proves to be nothing but lies and deceit, we might eventually end up with elected leaders that do as they claim they will.

The problem, obviously, is doing it peacefully. Maybe if the Egyptians get a few more rounds of practice at this they'll get it down to a fine art and invent* the next form of government.

*this is how you know I'm a Civilization fan.

Printable Gun Downloads Top 100k In 2 Days, Thanks to Kim Dotcom

davegravy Re:Uhm (656 comments)

Mod parent up.

There aren't many places on the net where you can go to discuss political topics rationally without emotional/inflammatory interference. You just don't get amuch of that on Slashdot, I presume due to the above average intelligence that most Slashdotters have in common (elitist as that sounds).

It's not part of the site's mission statement, agreed, but its uniqueness in this regard is what draws people to discuss out of scope topics. I don't think it's a bad thing.

Best course -- pray it turns out to have been a big gas leak.

It would be nice to return to the days of blissful ignorance when we believed we had no enemies or if the mounds of money and freedoms we give up for security would actually make us safe.

Ask Slashdot: Hacking Urban Noise?

davegravy Re:More details needed (474 comments)

How and what, exactly, have you insulated, and where is your domicile in relation to the street?

Do you have sound dampening mats on the ceiling? If not, bear in mind that most houses and apartments are above street level, and most of the sound will be reflected off the ceiling. A layer of sound dampening material there should have the largest effect.

If you live low to the ground, sound insulating the walls that can see the street, rather than just outside walls would have a similar effect.

There are two components to the noise intrusion - the direct field and the reverberant field. Adding absorptive finishes to the room will help reduce the reverberant field, which in a best case scenario will buy you 3dB (i.e a barely noticeable improvement). Short improving the isolation (i.e windows and exterior partition construction) there isn't anything you can do about the direct field.

A few strategically placed plants or sound dividers - think cubicle walls but far less intrusive - can also help.

Massive barriers can help in outdoor noise propagation scenarios. In this type of situation, the outdoor noise is impacting the exterior facade, causing it to vibrate, and is re-radiating sound in the interior of the OP's space. This means that the source of sound is a large area, not a point source. The sound is effectively coming from "everywhere", and so you don't get the same kind of path length difference attenuation from barriers like you do when you have a point source that is far from the receiver. This is exascerbated by the fact that the intrusion is low frequency which diffracts around corners far more than higher frequency sound.

Plants are not massive enough to be of any significant help. To put things into perspective, a dense forest that's 100m in depth will only attenuate sound 2-3dB, and that's mostly a high frequency reduction.

If you must go with a noise generator (which I don't recommend), try pink noise instead of white. The sounds from the street you try to mask out are going to be mostly low frequency, and white noise will mainly add more sound energy in the higher end of the spectrum.

White noise will add equal sound energy across the spectrum. Pink noise will add more energy in the lower frequencies. We don't typically recommend noise masking for low frequency intrusions into offices and other facilities we consult on because the masking is generally perceived to be more annoying than the original problem. It's best used when there is a speech privacy problem in large open offices because there isn't ENOUGH background noise.

Upgrading your window would typically be recommended, but will only do a little for low frequency. Note that in glazed assemblies, the framing is the weak point. STC 35 is where most frames will top out (even though the glazing will advertise higher STCs into the 50s). If you want a really solid window construction you need an isolated frame assembly which is two frames in series that do not touch each other and which are isolated from the surrounding structure using 3mm thick neoprene gaskets. Each frame supports a separate pane of glass. The inside perimeter should be lined with glass-fibre to prevent standing waves in the cavity.
Overall thickness of the glazing might be 2-3"

NZ Broke the Law Spying On Kim Dotcom, PM Apologizes

davegravy Re:Still not over. (235 comments)

Whoa Whoa WHOA!

That's not the kind apology the PM was offering. It was more a "sorry about your luck" kind of apology, not the "this is broken and needs to be fixed" variety.

US Military Designates Julian Assange an "Enemy of State"

davegravy Re:Freedom of Speech is such a smokescreen. (805 comments)

We need more of this. We need to know more about what businesses and governments do in secret to line their pockets by picking ours. The mainstream media can't quite be trusted to do so, I feel they're in the payroll of government and business -- so the last resort is.. this.

But, who vets this kind of leaks? Who can assure the reader that it isn't misinformation? Wow, paranoids are right, I think!

Still, there's a little place in my heart that tells me.. we really don't want to know. I think it could be that revolting, that repulsive.

Committing of atrocities by popular and powerful people has been a constant throughout human existence. It's safe to assume it continues today, to a degree as revolting as ever.

There's two types of people in this world: The blissfully ignorant, and those with futile optimism that awareness might breed change.

Samsung Beats Apple In Tokyo, Itching To Sue Over LTE Patents

davegravy Re:Why do we even have a Patent Office? (221 comments)

For example, sound and light from the device could be disabled when entering a movie theater, or communications with other devices could be disabled in a science laboratory.

How is that patentable?
Not only is a obvious, it is already implemented by various android applications. Tasker probably being the most famous.

Can you now patent stuff people are already doing?

While I agree, I'm happy to let Apple have all the patents it wants regarding locking down devices. It provides all the more motivation for Android to be open and free.

Google Granted Cloud OS Patent

davegravy Re:These type of patents are bad (143 comments)

That's like saying how bad a law is depends on how its used.

Laws which allow authorities unfettered rights to spy on citizens are good, provided the government doesn't use that power to persecute.


Laws which allow authorities unfettered rights to spy on citizens are bad BECAUSE they could be used by governments to persecute.

Is TV Over the 'Net Really Cheaper Than Cable?

davegravy Country-dependant (285 comments)

In my country a-la-carte works like this: the price per channel scales depending on how many channels you buy, such that the total cost you pay is always at least equal to the cost of the traditional bundle packages. It's totally pointless. Also in my country, over the Internet broadcast licencing hasn't really been established (for the most part).

The result is that over the net tv is far cheaper, but in no way legal.

Don't Super-Size My Smartphone!

davegravy Re:If consumers didn't want big phones (660 comments)

Agreed. My old Nokia may be "dumb" but it lasts the entire workweek (5 days...sometimes 6). Who want a phone that dies partway through the day? You would miss incoming calls.

Because technology evolves and eventually smartphones will last a whole week. When they reach that point, I'll know how to use them to their full extent. You however will be a while behind on that learning curve.

Also, for my lifestyle, battery life is of limited importance. I have inexpensive charging cradles at home, in my car, and at my office desk - and the routine to use these was not hard to develop.

davegravy (1019182) writes "Byron Sonne, the Toronto-based security consultant / chemistry hobbyist / geek who was arrested leading up to the Toronto G-20 for alleged plans to bomb the event, has been found not guilty of all charges.

Sonne was held in prison for 11 months without receiving bail and the ruling comes 2 years after his arrest. Sonne is considered by many in the Toronto security community as a champion of civil rights and a sharp critic of security theatre."
