  1. 802.11a and who needs wireless anyway? on Upgrading Wi-Fi — What, When, and Why · · Score: 1
    802.11a is generally much less crowded than 802.11 b/g and as fast as 802.11g. Wireless in a crowded area can suck quite bad.

    I'm trying to help out some folks with a network in their home office - at the moment there are Ethernet cables strewn everywhere and it's a hazard (not to mention constant cable failures from chair casters, etc.). Wifi seemed to be a likely solution, but when I arrived, I discovered that I can pick up 4, sometimes 5 nearby 802.11b/g signals from many places in the house, on channels 1, 6, and 11. The people I'm helping have several 2.4GHz cordless phones (including a very expensive 4-line one that would be painful to abandon). The neighbours on one side, believe it or not, have six 2.4GHz cordless phones (at least that's how many I've spotted around the house so far). I haven't been in the other neighbours' house but I wouldn't be surprised if it's the same over there.

    So 802.11b/g is pretty hopeless. I travel with an access point, and gave it a try, but the signal conked out every few minutes.

    I looked into 802.11a, but could not find a single router that did not get trashed in Amazon reviews and the like. If reviewers say it's hard to set up, I don't care about that. But they all had multiple reports of frequent lockups requiring resetting the hardware, which isn't acceptable. The situation here is such that any sufficiently disruptive technology problem, such as a router that crashes every few days, is going to require me flying 20000 miles (Asia to USA and back) to deal with it, and I would prefer to minimise that.

    So we've just ordered a pair of Netgear XE104 HomePlug switches to see if those do the trick. Based on what I've read, I'm optimistic.

    Where I live there aren't any 2.4GHz cordless phones (that I've seen) and wifi interference seems to be much less of a problem. It's all 1.9GHz DECT phones. But given the potential hazards of all this microwave energy in the home, I'm thinking of ditching the cordless phone and, if the XE104s work out, getting some of those for my apartment since I basically use the laptop in the same 2 or 3 places all the time anyway.

    The thing Americans often forget is that while Macs are fairly common in the US, they're almost absent in the rest of the world, while Linux has had very significant penetration, even on the desktop, in Latin America, Europe, and Asia.

    I live in Southeast Asia. There are two Mac stores within a 5 minutes' walk of my home. When I walk by Starbucks I typically see 2 or 3 Macs and 5 or 6 Wintel notebooks (running Windows; I am an incurable desktop-peeper). I went to a party on Friday, 3 people brought notebooks to DJ with, and two of those were Apple iBooks.

    Conversely, the only time I have ever seen anyone but myself using Linux on the desktop is at the Linux users group meetings, and even there a good share of the computers were actually running Windows. The only person outside the LUG I know who runs it on the desktop is a foreigner (from the UK) who uses it to demonstrate high-end software that runs on Unix and Unix-alikes.

    Electric subways are only feasible in certain places, and they require an enormous amount of capital to build. It's not cheap tunneling under existing buildings and infrastructure. Most US cities aren't dense enough to support subways.

    I agree; most US "cities" do suffer in this regard. Personally, I'd rather drown myself in a vat of lye than live (or make a prolonged visit to, for more than about a week) anywhere not dense enough to support subways, so my interest in such places and their problems is fairly offhand and highly abstract.

    Once you start making people who live in the sparser areas pay their own way rather than sucking money from the cities, the factors to which you refer may change. You may find that the population starts to concentrate, and/or that populations in outlying areas decrease to the point where congestion and pollution are non-issues. Would be a treat for the die-hard ruralists, I suppose.

    Diesel buses are quite nasty. Anyone arguing fuel efficiency for public transit is an idiot unless they're talking about 50 years in the future, because the buses on the road today are crap. There's a few places with diesel-electric or natural gas buses, but that's the exception, not the norm. Also don't forget, most buses are NOT loaded to capacity most of the time, so their passenger miles-per-gallon numbers are generally much worse. In general, public transit is very inefficient and very polluting.

    That's because in general, public transit in the USA is at a 3rd-world standard.

    Electric subways are fast and carry large numbers of people with decreased energy usage and pollution (depending on the particular power supply).

    This is utterly infeasible and unworkable. The problem is that cities want to maximize the number of vehicle stops at red lights, in order to frustrate drivers and make them either not drive or choose alternate routes. Google for "traffic calming".

    Traffic calming is used to encourage drivers to choose roads which are designed for higher capacity, yes. The idea is to ensure that traffic in residential areas with children playing and people trying to sleep is not a hazard or an annoyance. You'd have to really hate your neighbours to disagree with this.

    Not really. SMTP is unencrypted, so if you're relying on encrypted webmail to secure your e-mail communication your security model is probably wrong. The only things which should really need an SSL connection per se are changing your password and deleting messages; by implication logging in would also need SSL to set up a secure cookie for these.

    About half of my SMTP is encrypted; STARTTLS support is pretty widespread in MTAs these days. Turn it on in yours and you might be surprised.

    But in any case, the opportunistically intercepting a message or two is one thing. Being able to log into someone's mail account and read all their old and sent mail, read their new mail whenever you want, and forge mail from them with valid headers, is quite another kettle of fish, and considerably more serious.

    My first reaction was "Good Lord, how stupid can people get?" - I mean, does this mean that if you set up a wireless network in accordance with their regulations, and it still gets abused (through WEP weaknesses or whatever), they have implicitly invited you to sue them?

    But then I thought back to ohhh, yesterday, when I was wrapping up a work trip to Thailand. When I arrived I had bought a SIM card at a dusty little family shop and the cashier who installed it into my phone signed me up for a bunch of promo offers including the loathsome Calling Melody (which I never figured out how to disable) and 50 free hours of GPRS (pretty good considering the card cost me US$7.50).

    My hotels had free wifi so I didn't end up using that much of the GPRS time. Yesterday, at the airport, I figured I might as well use some more of it up, so I popped open the trusty iBook and turned on internet sharing with SSID name "Free Internet!"

    Within 15 minutes I had 5 or 6 people on it (must have been painfully slow for them). I was too tired to do anything useful, but just for the heck of it I started up ethereal to see to what ends my largesse was being used. It was remarkable how trusting (or probably ignorant) people were - as well as how many unencrypted port-80 webmail servers and office intranets there are out there.

    So maybe the real value of the rule in TFA is to protect the users from themselves, rather than protecting the AP owners. When you connect to an unknown AP you never really know what could be going on with your traffic unless you encrypt and authenticate it.

    Sorry, but no matter how slick the words, it is still depriving someone of the compensation for their work.

I can think of a few others: Working for someone who doesn't pay you the commission due, for instance, is not the same as armed robbery. Someone not paying you for the software you wrote for him is fraud. They are all forms of stealing.

    So you content that depriving someone of compensation for their work is "stealing"? Pretty iffy, but okay, I'll bite.

    How about if David builds a table with the intent to sell it, and I come along and build a better table for less money, and everyone buys mine instead? David has been deprived of compensation for his work.

    How about if David builds a table and it falls apart when he's in the process of delivering it, and I refuse to pay? Deprived of compensation.

    I don't know how you came up with the "average" cost of a house in Goa, but it is nowhere near that high. And Goa has a lot of foreigners bidding up prices; it's not typical.

    Rs1200 is a LOT for a meal. More interesting is the cost of meals you are likely to eat on a regular basis. You can easily eat out for US$0.50 at a basic place.
