How many devices are connected to your home Wi-Fi?

marienf Re:Why Fy? (260 comments)

I'm not sure if you're agreeing with me or not, except on the sports.
I agree not everyone can run wires all over the place, and that most studies are biased.

But that not everyone can run wires is like saying not everyone gets to escape air pollution: It's not fair, but it doesn't make air filters bad, or ridiculous.

Most studies are biased, but consider which bias is more likely: one forced by a billion-dollar wireless industry, or one invented by a bunch of scientists crying in the desert desperately risking their grants and careers trying to warn everyone ?

At what age did your friends start working on cell phone sites? The problem is especially acute for young children. But it's also a bit of a strange argument: We all know about the 95-year old uncle who has smoked all his life and is still going strong. There's always the exception, and there are many other factors at play in human health.

Tell me what you mean regarding that nuclear plant? It's a much different type of radiation.. I'm at 68.8 Km from the nearest nuclear power plant. It's such a small country that just about everyone is closer than 50 miles from one :-)

marienf Re:Why Fy? (260 comments)

While I certainly believe your experiment with the cigarette, and would expect cellphones, which are much closer (and much more powerful) to have worse effects, just like you would, it is far from certain that we may continue to rely on dose-response in the case of modulated microwaves. In some cases, lower exposure got worse results: some cellular defense mechanism failed to trigger at very low doses but damage still occurred.

That is not true on many levels. While the sun outputs a lot of
radiation at many walelengths, it does not produce all of these in equal
amounts, and while the bands we're talking about here (>800Mhz to say
4Ghz) are not absorbed much by the atmosphere, in the end, the amount of
energy reaching the earth's surface is still not that much.

The sun produces microwaves in several, specific bands, related to
different phenomena in different layers, but the most-studied appears to
be the 2.8Ghz solar flux.

For example, in the

Penticton/Ottawa
2800 MHz Solar Flux .. graph you see a peak at about 30 x 10^-22 W/m2 of 2800Mhz solar flux.

That's .000000000000000000003 Watt per square meter at its peak.

I took out my flux
density meter. It has a range between 0.0 and 2000.0 uW/m2 in the
800Mhz to 2.5Ghz range.

This makes sense because the most conservative norms at this point (the
norms that I'm using), the 2008

BAUBIOLOGISCHE RICHTWERTE (German) have less than 0.1 uW/m2 as an ideal situation
for a bedroom.

I have a general background radiation in that range of about .2 uW/m2 in our garden, in the radio-shadow of the house opposed to the nearest Cell Mast. the HFE35C has a speaker so I can hear an impression of modulation of what I'm pointing the directional antenna at. Mostly, it's Wifi, GSM, 3G, etc.. which I've
learned to recognize.

The neighbour's Wifi, after some careful targetting, is about 7 uW/m2 on
the first floor, through the open window facing them.

That's .000007 Watt/m2 measured through at least one solid wall and
about 15 meters of air.

That's 2.3*10^15 (2,333,333,333,333,333) times the microwave flux from the sun at it's peak, at 2.8Ghz.

When I take any of our laptops and enable the Wifi, at one meter from the device I'm off the HFE35C's scale (greater than 2000 uW/m2).

A cell phone registers as a kind of explosion and is obviously, many time off the scale. Most cell towers, in line of sight, are, as well, from 50m or more.

So those are worse than 6.6*10^17 more intense than solar microwaves at
close range.

But all of this doesn't even really matter. Even if the sun would irradiate the surface with effectively the same or higher amounts of microwaves, I would still not expect much or any biological effects becasue of the type of modulation (not) occurring on the sun's microwaves. Unmodulated microwaves have biological effects only though thermal effect, and that has been proven to be negligeable at low exposures.

If you bother to read the research, it's the MODULATION that gets everyone worried today: Biological effects occur for low-level HF exposure when the RF is modulated, especially with square waves.. e.g. digital data.. What is a laughably safe dose for thermal effect (solar, Wifi, DECT, Bluetooth, ..) suddenly shows serious impact when modulated with square waves..

Best Me With Research, not Ridicule.
It's a lot of work and I'm going to give up if I get more lazy answers.

> Go figure.

I sure hope so, or we would be in a bit of a global predicament :-)

But as you might discover when doing a bit of research, there are many types of radiation, and the biological effects are not the same for all these types (go figure :-)).

For sunlight, these have been studied much better than modulated microwaves have ever been, and this has shown some hazards, which is why noone finds parasols, protective substances to rub onto the skin, and finding shade a strange thing to do. Now some folks are concerned about modulated microwaves, even at the low doses you're trying to make fun about, and I would prefer to stay our of that particular sun until there are some definitive answers about that.

> Hey....how else am I supposed to watch football when I poop?
Don't even get me started on ball sports..

> Ever consider someone who works from home, and works on a computer?
Yeah.. because that's what I do 6 days out of 7.

> What's the point of not being in the office if you're still tethered to a location to work
Quiet, fresh air, own music, company, not commuting for hours, etc.. Also the wiring is just about everywhere.. I mean: I don't work on the ceiling, in the toilets, bathroom, entrance hall, etc.. nor do I really want to. Referring to your opening remark: I hate watching sports..

> Maybe I want to...I don't know...sit outside on a nice day and do some work.
And I do so at every occasion. There are Ethernet and power plugs at various spots in the garden..
most of these spots are still below 4uW/m2 in terms of microwave exposure, so I don't worry much about that, and I love being outside. We don't want to get to a point where we lock ourselves up: That would represent far too high a social cost.

> You're just one of those paranoid tin-foil hat types who probably only feels secure in a cubicle
I was wondering when the TFH would come up. As a matter of fact, I have refused jobs that required me to sit in a cubicle or on any type of open space with lots of noisy people, for years. So, no, sorry, don't feel secure in a cubicle.. Quite the opposite. Besides, those offices commonly have Wifi, DECT, lots of BT devices and colleagues on cell phones.. So not really my favourite place for that reason also.

> Technology has allowed us to no longer be tied to a terminal..or a room...or a building...or even a populated location
So.. because I've solved my particular needs for workspace freedom using wires, and you have solved it using microwaves, I'm more tied than you are? And how does the capability of that technology to work "anywhere" make it desirable or useful to do so? And especially: is that perceived freedom worth the health risks? If I were a rescue-worker, I would happily risk working with a microwave-based comms device on my head for hours, because in some situations, it's just safer to do that than to lose contact with your colleagues. But I believe those are extraordinary circumstances.

> I probably wouldn't want to associate with a paranoid job like you in the first place..
Sorry to hear that. I would humbly suggest you have a good night's sleep and read up on some modern research on biological effects of RF, and perhaps come back to this discussion afterwards.

> IOW, you don't know, but are happy to toss out an AC snarky comment.

That's right: I don't know, so I rely on research of others. I find serious concerns, compare the potential but likely health hazards to the cost and inconvienience of shielding, and conclude it's worth shielding, in our case.

BTW: Cool job, on the radars!

> What amount of that RF is being converted to heat in my body?
The heat doesn't matter at those doses.. Just about everyone agrees about that. We should stop hiding behind the thermal effect which is benign at low dose. It's the cell metabolism, endocrine, genetic, blood-brain-barrier etc.. effects that these scientists worry about.

Eternally hiding behind the one effect that has been well-established as non-problematic at low doses: The thermal effect, we're ignoring all the other effects, there is a whole list, these do occur at low doses, are insufficiently researched, and IMHO the preliminary results look very bleak.

marienf Why Crazy (was: Why Fy?) (260 comments)

So, if modern research casts serious doubt on both the dose-response and thermal interaction approach, suggests low doses may be dangerous and concludes that much more research is required to declare low level RF safe for humans, my family and I are perfectly fine with a shielded house, why is it crazy to avoid that risk? We're not losing anything (except the investment for the shielded paint and grounding accessories), and we're potentially avoiding a major health hazard to the best of our abilities (we're not walking around in tin foil hats or conductive hoodies or anything, but at least, in the home, we give our cells a break (pun intended)).

"Protection against Non Ionizing Radiation is based on a paradigmatic assumption: We know very well the interaction between electromagnetic fields and living organisms: it is a thermal interaction; thus the standards internationally accepted are adequate to protect people and workers.

Now I would be extremely interested to hear why my comments would give you that impression?

Is it

- the fact that we live in a well-wired home?
- the fact that we live in a shielded home?
- the fact that we ask visitors to leave mobile devices in the hallway or switch to airplane mode?
- the fact that I don't see any use for mobile devices in the (well-wired) home?
- the fact that I don't use any mobile device, at all, personally (I have no use for it)?

Agree with hooiberg.

Before we moved in, we had the electricians add Ethernet + Coax all over the place.
We now enjoy radiation-free hard-to-tap full-duplex high-speed reliiable connections everywhere. The phones are VoIP models and on that same network, so are our laptops. I don't see the point of making a very simple problem complex and unreliable. I don't see the point of Wifi, in short.

In fact, we went One Step Beyond, shielded our home, and banned all microwave-based devices (except the oven, which is in a well-shielded switched enclosure) from it. Our visitors leave their cell phones etc. in the hallway. A bit like guns in some saloons, back in the days, I guess.

The quality of our social gatherings has certainly improved as well, with people not looking stressed and preoccupied with checking their little screens and allowing these to interrupt face-to-face conversation, and we enjoy 1uW/m2 throughout the home, just to be on the safe side.

What's the point of having a mobile device *in the home* in the first place? I certainly don't see it, and while I personally don't use mobile devices at all, I can sort of see how these can be useful while on the road. But in the home.. That's just plain silly.

Not Just Apple: GnuTLS Bug Means Security Flaw For Major Linux Distros

marienf Near Zero Impact (144 comments)

Agree. I've ran through everything that linked to gnutls on my distro (Arch) and although there's
quite a lot of binaries that do, most of those do not offer TLS connections (or any network connectivity at all), so my
guess (without knowing GNuTLS at all) is that they use some other feature offered by the library.

Of those that I know actually capable of SSL/TLS connections, all (also) link to OpenSSL.

So without making a definitive statement, AFAICT this should have near zero impact on GNU/Linux.

With HTTPS Everywhere, Is Firefox Now the Most Secure Mobile Browser?

marienf Re:who are we fooling? (279 comments)

> So what are you proposing instead?
I'm proposing to stop outsourcing most PKI to central authorities, making the "trust" a conscious user decision.
Now before you argue that I can remove all authorities from my browser and add exceptions as I go, this is not a solution as what I will find
is single-signed by some company I have no way of checking. If what I found was multi-signed there would be a reasonable chance of determining
a level of trust via my web of trust. e.g. I would have something to go on while making that decision.

> I think the whole point of HTTPS Everywhere is that using it is better than not using it.
Sure, but HTTPS (SSL, TLS..) is not what I have issues with. What I have issues with is using certificates single-signed by central authorities and preloading these into client software.

> As security increases, convenience decreases.
I cannot argue with that :-) I just think it's necessary.

With HTTPS Everywhere, Is Firefox Now the Most Secure Mobile Browser?

> against dragnet surveillance attacks like those performed by the NSA, GCHQ, and other intelligence agencies.

While I certainly think it is a good idea to encrypt traffic, this statement is highly misleading or naive: Since the CA
system is *flawd by design* and every one of those "authorities" in the long list of built-in CA inside
your browser can, by negligence or choice, supply any of these and other agencies with a valid certificate for
*any hostname in the world*, initiatives like these protect your privacy only from your local sysadmin/ISP, and also
do nothing against traffic analysis.

Should a US person/company trust that "China Internet Network Information Center" isn't going to create a cert for a
US bank or company to perform a MITM attach with? Should a Chinese company trust "Wells Fargo" not to?
Should the Greeks trust "TÜRKTRUST Bilgi letiim ve Biliim Güvenlii Hizmetleri A.. (c) Aralk 2007", or the
Turks "Hellenic Academic and Research Institutions Cert. Authority"? What on earth makes you think ALL of these
companies can resists pressures to misbehave? Yet all of them are built-in to your browser and "you" trust them.

Just go to any (Cloudflare, Akamai..)-accelerated site using https and check out the certificate used to see how that works:
They are issued certificates for the customer domains they accelerate, and hence have access to all the traffic.
In essence, they do exactly what a man-in-the-middle attack would do, except on a much grander scale (and with the collusion
of the actual domain holders). The agencies can carry out such attacks from within the ISP's, and your browser would still show "green".

The Cert validation in the browsers leads to a *dangerous false sense of security* at most. This is crypto, a weakest-link business
if ever there was one, folks. It's not ALL, or SOME that need to fail in order for PKI to fail, it's ANY of them.

Surely, we can do better than that: We should get rid of all centralised security illusions. Why aren't we signing contents using our PGP
keys that at least make multiple signers possible and habitual, and, and this is the essential difference, IMHO: That *you* have made a
conscious decision to trust or mistrust, to a certain degree, by reviewing a web of trust, as in informed consent as opposed to blind paternalism
of massivly built-in, pretrusted certificates by distant companies you really have no clue about.

Is the World Ready For Facial Recognition On Google Glass?

marienf blinders are effective in low light (469 comments)

Anyone know if those LED baseball caps really work? What about a can of spray paint, aimed at the Glass-hole?

This looks promising, it's an IR based 'camera blinder' that hides your face:
http://www.slashgear.com/surveillance-cam-blinder-2010369/

Dunno how effective it is against different camera types and it does require you to wear a dumb-ass headband but it looks like a promising concept.

I've been playing around with various IR LED types, such as this one, at a couple wavelengths, and I found that in darkness and twilight, you need only very few to become a huge blob of ghostly light, but in good lighting conditions, a good camera like an Axis P3367 and even some of the crappy webcams I tried will see them as merely little points of red light. So I'll integrate a bunch in my backpack's straps and on it's surface, to at least get that commute, including subways etc.. covered, but with little hope of completeness.

So the real challenge may be: can we build a device that automates lens detection, focuses a small laser on the lens in question, and keeps it there while both the lens and the wearer of the countermeasure laser move along. +1 for a switch that will briefly increase laser power to burning strength. As in using a 2W Laser diode at low power. Capability :-)
