Tech question, with a young 'un around the house, I'm reluctant to get wi-fi set up, so currently run a lan wire from modem (cable) to laptop (powerbook). My desk is across the room from the modem, so if I wanted to run a cable (which would involve going over a door and along about six feet of skirting) would it be best to run a coaxial and have the modem shifted to the desk, or a long lan wire and leave the modem where it is?

1) Why does having a child affect whether or not you have 802.11 (wireless)? Are you afraid that the signals will cause cancer or electrosensitivity?
2) Coaxial cable has a data transfer rate of about 30 mbps per channel. Depending on how recent your computer, your router and your cabling are your Ethernet connection will either be 100 or 1000 BASE - that is, with a nominal transfer rate of 100 or 1000 mbps.

So, functionally, I doubt it makes much difference - your broadband connection is unlikely to be able to output enough data to max out either cable, unless you have business-grade cable Internet. If you want to experiment, go to speedtest.net and check your download/upload speed with both options, but I doubt any difference will be noticeable. If I were you, I'd probably put the modem wherever it is least obtrusive and easiest to connect to a power socket.

For reference, 802.11b (which I assume your powerbook has in its Airport card - if you mean Powerbook as the type of Apple laptop replaced by the Macbook and Macbook pro moments after I bought one rather than as a generic term for an Apple laptop) has a data transfer rate in ideal conditions of 11 mbps, so it's notionally slower than both types of cable, but over six feet and with a normal cable broadband connection and normal usage I doubt you'd notice. If your Powerbook is basically static, and you have no other devices, tethered or wireless are probably equally effective.

1) Yes, pretty much the thinking
2) thanks

ta haus; and i had thought the plural was 'es' - like in octopus - as the word is greek, not latin, therefore not 'i'... but answer away at any question, asked or no - always a good read!

and just 'herd'? how boring for such a very non-boring beast... we need 'lith to make up a better one than that!

Octopus is the same - "octopuses" or "octopi". The words have Greek roots, but actually what you're using is a Latinisation of that Greek word creating for taxonomic purposes - so hippos potamios is Latinised to hippopotamus, which follows standard second-declension rules - so, like "stadium", you have an anglicised plural (stadiums) and a latin plural (stadia).

Benny, have you looked at Powerline?

I'm assuming that you would prefer not to run wires around skirting and over doors, given that you mentioned wireless, and are therefore not averse to spending a bit of money.

If that is the case (and obviously this is significantly more expensive than a long ethernet cable), then I'd wholeheartedly recommend Powerline. If you've not heard of it, it uses your electric ring to send data signals, and a kit consists of two plugs that also have ethernet sockets on them. Plug one into your modem and a nearby socket, and the other near to your laptop, and voila. Job done.

I use these to link my modem (which comes through into my lounge at the front of my house) to our computers (which are in the room at the back of the house), and they work flawlessly, with no extra wiring needed, and set-up consisting of literally no more than simply plugging them in.

Thank you, I'll have a look into those.

Is there actually any well-controlled research on the effects of wireless signals on health? I mean, we're perpetually in a soup of electromagnetic radiation coming from all over the place anyway; hell, any current through a wire will create an electromagnetic field, not to mention all of the naturally occurring signals. The PowerLine system mentioned upthread will certainly cause your house wiring to act as an antenna; this very effect is why broadband over power lines has not taken off - it would end up wrecking a huge chunk of spectrum due to the interference.

I understand wanting what is best for the little one; it just seems a bit absurd to me that a low-power wireless signal would make any difference relative to the effect of the background overall.

If that's a Q looking for an A - no, there's no peer-reviewed data suggesting that 802.11 wireless broadband has any adverse health impacts that I know of. If you're in an urban area, you're likely to get your neighbours' signals anyway, and in a few years urban WiMAX will make the whole question somewhat academic. I'm not sure how you'd go about getting that data, to be honest - you'd need to isolate people from other electromagnetic stimuli for quite a long time while they are plonked next to a wireless router.

How does one go about applying for an American greencard?
There seems to be many, many sites on the web to do with this... however.... is there an wholly official manner in which to do it?

Did you try this?

01:09 / 06.01.09
Cool Tsuga, I'll have a look, meant to say 'Greencard Lottery' if that makes things clearer.
I'm pretty sure I can get a year long working visa, and then apply for sponsorship from a company should I be working for somewhere reputable enough...
Hmmm, unsure but its stuff I'll have to beginning to look at if I plan to move.
Covering all bases.

Mirror, can I ask you to clarify this for me?

The PowerLine system mentioned upthread will certainly cause your house wiring to act as an antenna; this very effect is why broadband over power lines has not taken off - it would end up wrecking a huge chunk of spectrum due to the interference.

Does this mean that whatever (if any) "harmful" effects might come out of a wireless router are being replicated anyway in my house by my Powerline system?

(I have wireless anyway, so it's an academic curiousity, not a personal "I'm worried" one). Cheers.

So tell me Barbelith, are full deposits usually payable on flats for short term lets of three months or less? Obviously you can wreck a flat in a day as easily as a year, but there is also a certain amount of wear & tear to take into account in the latter case.

Any ideas?

Neon Snake:

A bit on antennas first; basically, any wire with a current running through it will act as an antenna; i.e, it will generate an electromagnetic field. Of course, house wiring isn't a very good antenna as it is not engineered to resonate at any given frequency; radiation represents a loss of energy. What these power system broadband units do, to the best of my knowledge, is add a high-frequency digital signal to the primary 60Hz carrier wave. In large-scale application, at least, this has been shown to produce significant interference on ham radio bands (i.e. power lines act as antennas, but the frequency at which they radiate ordinarily is outside of the bands used for communication.) The high-frequency digital signal changes this; I'm not entirely certain about the physics of it, but there's more information available here on the interference produced by commercial BPL tests.

Anyone can help me with this?



This is a photo of Israeli soldiers and some weird machine, that I saw this evening on the online news. What is that thing? Anyone know?

I believe that's used for catching butterflies.

It reminds me of those jawa cars. Maybe the designer was an OT fan? But I´d really like to know what that is supposed to be/do. The front looks like drills.

It's a bridging vehicle, isn't it? It looks like the two parts on top unfold to form a bridge over small rivers and such-like.

Mirror: Thanks. So, the guys promoting Powerline as a way of avoiding any (potential) negative effects of Wi-Fi are incorrect, then?

Yes, that might be what it is. Thanks! What I thought were drills probably look like the teeth of an excavator´s bucket from a different angle.
 
 
Tsuga
22:59 / 10.01.09
I thought about a bridging vehicle, except that it's so pointy at the ends, and the appendages look diamond-shaped. It could be deceptive, and the pointy bits are actually track ramps, the diamond shape is engineering.

I have a question, actually:
I received an email from my ISP, Verizon, a "notice of claim of copyright infringement".
They do say The copyright owner has not asked Verizon to identify you, and Verizon will NOT provide your identity without a lawful subpoena or other lawful process. However, if the copyright owner does issue a lawful subpoena or other lawful process that seeks information about your identity or account, Verizon will be legally required to provide the requested information to the copyright owner.

I'm not too worried, but should I be?

An ex GI just confirmed that is indeed an "AVLV" (Armored Vehicle Launch Bridge).

Could it possibly be a phishing scam of some kind?

You look positively glowing in comparison to the heroin chic look you were sporting a while back. Pink still suits you though.

I just realised that heroin chic is an anagram of heroic chin.

Yes. And would that also make Christian Bale in The Machinist an anagram of himself in Batman Begins?

deeper.
