Yeah, I understand. I thought Star Trek transporters were creepy for the same reason. But imagine a technology where your neurons were replaced gradually individually or in small groups. If one neuron were hot swapped for a transistor, you'd still be you. Your brain would still process the same thoughts and patterns in the same way, only part of the process would be running on a nonbiological construct. Now replace another one, and a few more. You're still you. Same patterns, same body, same circuitry. Repeat the process until your wetware's been entirely replaced by circuitry. At no point were you not you, any more than when you slept at night.
I would do my best to stay healthy and hope for medicine and robotics to improve so any organ that fails can be replaced.
This. Exactly this. I don't want to live to be a 150-year-old drooler in a dementia ward. I want to live long enough that I can make the transition from physical to digital existence. When your mind is online, you don't have to worry about your knees wearing out.
I'm serious about this. I know a lot of people dismiss Singularity-type thoughts, but I can't see us not having the technology to make this possible and common within the next hundred years. In my life, I've gone from home computers with 1KB of RAM to 8GB, and from data cassettes and 170KB floppies to multi-TB home servers. My MacBook can't emulate a human brain today, but it's several orders of magnitude closer than we were a few short decades ago.
Excellent point, and if I ever update that howto (it's in my GTD list - honest!), I'll recommend it highly. If you're using Postfix, check out its new postscreen server. It's so good that I dropped greylisting altogether.
I don't think so. It allows fake addresses like "no-reply@example.com" through. But in my opinion, senders like "somebot@foo" are a certain sign of spamminess. Like with watching the HELO failure logs, I never saw anything remotely legitimate looking get blocked.
Reverse DNS doesn't have to match the domain that they are sending mail from. It should just match the name that the mail server is presenting when it does a HELO.
Absolutely. In fact, it's extremely rare for the mailserver to have the same name as the mail it's sending. For example, I got an inbound connection from mail-yw0-f63.google.com to deliver a message from somelist@googlegroups.com.
It's been a long time since I wrote up some spam-filtering instructions, but I'd still stand by most of my recommendations. In general, yes: just increase the spam score. I do have several litmus tests, though. If you fail one of these, I'm not accepting your mail:
Your HELO has to send something that actually looks like a hostname. "server" doesn't work, and neither does "5626^^^". Rationale: a server this badly misconfigured is either a spambot or so horribly broken that I don't want to talk to it. I look at the output of this rule from my logs and I've literally never seen anything blocked that looked like it might have been legitimate.
Don't send me my own hostname in the HELO. You're lying. The only reason to do this is to trick me into relaying for you.
Don't send mail From: an unresolvable address. "someone@server" isn't a legitimate email address. Neither is "joe@nonexistent.example.com". If it would be impossible to send you a reply because the address you've given can't possibly be valid, I don't need to hear from you.
I use zen.spamhaus.org, bl.spamcop.net, and b.barracudacentral.org to generate a likely spam score for incoming servers. If their combined score exceeds a certain threshold, I outright block email from that server. A server might accidentally end up on a blacklist, but it's unlikely that one would accidentally end up on more than one of those (in my opinion and experience) very conservative lists.
"Be liberal with what you accept" is a great idea to a point, but there are some things that correlate very strongly with spamminess. Back to the subject at hand: I don't think that lack of reverse DNS is one of those things.
It would be impossible for me to disagree more. In my experience, users have almost no idea what they really want.
For example, regulations require us to maintain digital copies of documents that we transmit to other parties. One day, I walked through the room where we keep all the scanners used to digitize all incoming paperwork. I noticed a thick stack of neatly-ordered paper (as opposed to the small stacks of random shapes and sizes we usually receive in the mail). When I asked what it was for, the woman running the scanners told me that part of her job was to print out our outgoing documents and scan them in to our fileserver.
What she really wanted was for outbound documents to be automatically stored somewhere. When asked, what she thought she wanted was a faster scanner.
Everyone here knows how it goes: I ended up being the unofficial tech support for all my friends and family. Even after swearing that I didn't know much about Windows, I accidentally helped someone clean up their PC and word got around. Anyway, I have a patented plan for fixing two-year-old computers that run like molasses: 1) uninstall Norton, McAfee, AVG, and ever other antivirus program I find; 2) install MS Security Essentials; and 3) make them buy more RAM.
MSE doesn't have a vested interest in visibly demonstrating that it's still running and that you should renew your annual subscription you last renewed a month ago. Upgrading from the seemingly universal stock 1GB of RAM to 3 or 4 (depending on their CPU and OS) makes an enormous difference.
I move to the menu, click on it, click on the section I want and click on the application I want. It starts. I use the mouse to interact with the application.
LOL. So you've never used Windows? More like click the menu, click "Program", click the name of the publisher, click the application, and skip past all the uninstallers, readmes, and links to money saving coupons to find the app you want to launch.
The Start Menu, done right, is a great idea. MS never came remotely close to doing it right.
Well, yeah! Unless you have major governments looking over your shoulder, the physical damage from a drill (both in the form of holes and the warping and cracking of the glass platters) will take care of almost any attacker. The equipment needed to pull data off a drilled drive would cost way more than a petty thief could earn from swiping your credit card information off it.
When was the last time you voted or even contacted your representative based on copyright? I never have. Maybe I should, but there are other things I care about more.
It doesn't have to be either-or, you know. You're entitled to communicate with your employee on several different matters of lesser or greater importance to you; you don't have to pick just one.
This bill is dead on arrival that the House, which is Republican controlled.
Yeah. Too bad they couldn't have passed the bill in 2009 when there was a Democratic house, senate, and president. If Obama were serious about this, he would have proposed the legislation when it stood a good chance of going through. Instead, he waited until it could be used for political points to complain about anti-budget Republicans in the 2012 presidential race.
Face it: Bush the Third had no intention of ever passing this proposal. This is nothing more than political grandstanding.
The Playbook was designed to work with your blackberry.
You say that like tethering your shiny, new product to your old, dwindling-market-share product is a good thing. In reality, it narrows your potential market to people who currently own and are still committed to BlackBerry phones. In contrast, you can buy an iPad or Galaxy Tab and start playing with them right away without investing in any of those companies' other products.
It seems like a smart move to me!
It could've been a smart move with RIM was still relevant. It's sure not now.
I'm not so afraid of being caught and arrested or tortured or anything like that as of being caught and having to throw my knife away or race back to check my carryon.

Not according to OSHA, orthopedic surgeons, or ophthalmologists. We're evolved to look downward more easily than upward.

Git and Mercurial are far more complicated than need be for anything but the most complex projects.
Couldn't agree more. I mean, git commit -a; git push and git pull are an utter bitch to remember.
You know, you don't have to use their every feature just because they're there.
If your heart acquires strength, you will be able to remove blemishes from others without thinking evil of them.

Asking out of ignorance of Windows administration: can't you script that so that you could be up and running in 3 seconds or less?

I'm not sure what you mean, but I've been tunneling IPv6 with OpenWRT for quite a few years now.
Gnome's been great to me. If it hadn't sucked so badly, I wouldn't have given up on Linux desktops after 13 years of trying and gotten a Mac. Thanks!
