  1. Re:Call Barack Obama on New FISA Bill Would Grant Telcoms Immunity; Vote Is Tomorrow · · Score: 2, Insightful

    The usual advice on influencing politicians is not to threaten them. I heard from one of my state legislators that he tuned out $CAUSE activists because all they ever did was criticize and threaten, never acknowledging when he met them halfway and never putting their volunteer time where their mouths were.

    >you will refuse to donate or organize in the future if he refuses to take the lead on this issue.

    And if you do, save the nuclear threats for nuclear attacks. This issue shouldn't be a dealbreaker when we're still fighting about habeas corpus.

    What about students who score off the charts on ability but have given up on the school system? A single teacher spending a little time to point out interesting resources or to demonstrate that ability is valued can make a decisive difference.

  4. Poverty definition on Helping Some Students May Harm High Achievers · · Score: 1

    >You know who exactly are poor, right ? It's the 10% lowest earners.

    >And in a total surprise, everybody is totally shocked and utterly amazed ... ~10% of people are poor.

    Since 1965, the US government has been basing the threshold for "poverty" on the Orshansky measure, which is based on expenditures needed for a minimal standard of living.

    There are some problems with the way this is calculated, which may understate poverty: "The present system is based on a minimally nutritious food budget devised decades ago by the Department of Agriculture. The food budget is multiplied by three because back in the 1950's and 60's food was considered one-third of an average family's outlays.

    Neither the food budget nor the multiplier have changed in all these years, although food is less than 20 percent of the average family budget today."

    In this century the official US poverty rate has ranged between 11.3% and 12.7%.

    Your credit card number, if you still buy things over the phone. Somebody malicious could do worse things with your credit card number than just running up your bill.

    If you're in a position where someone might feel motivated to spy on you, for example being a spouse who's constantly "working late" or a reporter publishing damaging leaks, then you probably do have something to lose from having your privacy violated.

    Then there's the whole matter of principle. If I found a camera in my shower I'd be pretty steamed (pun intended) even though my showers are not really something that could be used against me.

  11. Casualties of TMI on McCain Backs Nuclear Power · · Score: 3, Interesting

    >Number of people dead due to TMI incident: zero.

    More than that, depending on how you look at it. Losing the wrecked reactor and shutting down the one next to it meant that the reactors were no longer saving lives by displacing coal. A nuclear power advocate named Petr Beckman took the Office of Technology Assessment figures for premature deaths due to coal use and calculated that having those two plants off the grid cost 100 lives per year.

  12. Waste disposal on McCain Backs Nuclear Power · · Score: 4, Insightful

    >They all have at least one good point though: what do we do with the waste?

    Power plant equality, now!

    Why not hold all power plants to the same standard?

    The mercury from a coal plant doesn't decay. It stays toxic forever.

    Vitrifying nuclear waste is already a better solution than the one used for coal plants, which is to dispose of the waste in the downwinders's lungs.

  13. Proposed code of ethics on Confessions of a Wi-Fi Thief · · Score: 1

    Let usage be governed by the intent of the access point owner.

    If the SSID says "Free WiFi" then it's OK to connect. If the owner has set up anything, even WEP, to control access you should assume they're denying permission and stay off. If the owner allows connections but sends you to a captive portal that says it's for business partners only and if you're not you should disconnect, then you were OK up to the captive portal but should disconnect otherwise.

    The reason there's a debate is that the owner's intent is hard to discern given the current technology. If the SSID is Linksys, then if possible knock on the door, introduce yourself, and ask. That often isn't feasible.

    In really ambiguous cases, fall back on the Bedouin tradition for using other people's wells while traveling. The standard there was that you were supposed to allow passing travelers to drink at your well, and that you could do the same on your travels, but that if you tried massive or commercial use such as watering your whole flock of livestock then desert dispute resolution techniques would come into play.

    The equivalent for us would be not downloading ISOs or videos from someone else's wireless connection.

    And of course don't use it for anything that's considered illegal: no unauthorized downloads of commercial music, for example.

  21. Security policies on Building an Effective Information Security Policy Architecture · · Score: 3, Insightful

    You always have a policy. It may be implicit, relying on the experience and intuition of the technical people. It may be dysfunctional, like "everything goes". Or it may be written down, which I gather is the sort you find useless.

    Written security policies are just plain indispensable if you're covered by PCI/DSS or HIPAA, since both standards require them. They also give you a way to do knowledge transfer: before a written policy, the technogeeks know not to download free toolbars, after a written policy everyone does.

    Anything good has a policy underpinning it. Are the backup tapes encrypted? If so, it's because there was a policy decision to encrypt them, even if that decision was made by an empowered IT person rather than a suit or a consultant.

    >You can't identify sensitive information assets because there's just too much data and no one can agree on what's sensitive and what's not.

    You can identify enough to be useful. Customer credit card information and health records are things people can agree on, especially when external forces require them to. Protect the things you know are sensitive, and you can reduce the risk of something damaging or embarrassing happening, and reducing the risk is all you can hope for anyway.

    Two issues here.
