    What makes you so certain that a CA who publicly acknowledged a breach would not also immediately die in a meltdown? There is no evidence that honestly in a similar situation would save a CA.

    If Digital Signature Trust Co.* were to publicly announce "We discovered just this morning that we have been breached, and while we can't give complete details because of the ongoing investigation, we found the hackers forged Google certificates," the public reaction would be almost identical to that of DigiNotar. If I were a customer, the chances would be high that I'd be shopping elsewhere for new certs to replace the ones that I could no longer trust. If I weren't a customer, there are obviously more reputable places to buy a cert. The incident itself is enough to cause me to lose trust, and that's really the only thing they're able to sell. I predict they'd go bankrupt as well, it might just take a few months longer.

    Perhaps hiding the breach for the extra months was a strategy to give the executive rats time to flee the sinking ship. If so, we can only hope their behavior catches up to their personal reputations.

    Agreed. The right kind of labeling tape is really important, as is the marking pen you use. Some inks fade remarkably quickly over time, or are dissolved by the solvents evaporating from the adhesives. Even if that crappy painter's masking tape magically holds for ten years, you still can't read if the coax is going to the bedroom or the kitchen.

    You can buy little booklets of purpose made cable labels, which are good for letters and digits, but not for descriptions or names. They're very cheap and portable, you can keep a supply in your toolbox, and they work great for tagging the in-wall socket ends of the cables as well as the sockets themselves.

    If you're doing a lot of work in one area, or don't mind carrying a label printer with you, get something like a Brother P-Touch labeler. They make ruggedized portable printers that you can toss in your toolbox. Get tape that begins with the letters TZFX. It's the flexible ID labeling tape recommended for cables. It's suitable for flagging as well as sticking to itself if you have to wrap it around a cable you have yet to pull.

    I know exactly what you want, because I wanted them too. I really wanted to get rid of my collection of wall warts and replace them all with some unified wiring system. My power supply is rated to handle all the accessories I have plugged in, so it's not a question of capacity. Unfortunately, I have never found anyone selling 4-pin Molex to coaxial power plug type adapters. So I made do with house current solutions, like everyone else.

    A few years ago I got sick of the rat's nest of wires beneath my desk, so I took a lazy Sunday afternoon to address the problem. I first used a labeler to mark every power brick with the name of the device it was powering. I then unplugged everything from everything, and moved all of it away from under and on top of the desk, completely opening the space. I bought two 12-outlet power strips of the industrial kind that use ordinary duplex outlets mounted inside a plain steel box. The spacing between outlets is large enough for most power bricks. I then screw mounted the strips high up under the desk, and have one plugged into the UPS, while the other isn't. Another label identifies the one that is battery powered. The wires from each are routed to the individual devices, in bundles through the holes in the desktop. The slack of each is bound up with a black twist tie near the transformer.

    Because it's dark under the desk, I clipped a small $10 clip-on reading light from Target (the kind with the wheeled switch on the cord) to the underside of the desk, and can turn it on whenever I'm working down there. It really helps. Even with my old eyes, I can easily read the faint markings and see the colors of the audio connector plugins.

    I have all the wires to the back of the PC routed and velcroed together so I can slide the whole cabinet in and out from under the desk without straining any of them (except for two peripherals with wires that are too short.)

    I mounted a third power strip to the inside wall of the hutch over the monitor, where it is mostly out of sight, and I use its outlets for temporary devices such as camera chargers, family PC's being repaired, etc.

    It's occasionally devolved over time as devices have come and gone and I didn't take the care to bundle things up nicely in their wake. Earlier this year I got sick of it again and did a bit of tidying up, but it was much easier this time. I just had to retie a few bundles and all was clean again.

  11. Re:Velcro wraps... on Ask Slashdot: Clever Cable Management? · · Score: 1

    It depends largely on the physical properties of the cable being tied. The softer the plastic of the outer insulation, the easier it is to damage. Wires designed for use in automotive or machinery applications are made with tough insulation to protect against vibration damage. Many types of cable sheaths include internal fibers to increase the physical strength, or maintain the shape and stability of the cable's cross section.

    High performance cabling such as Cat 5e / Cat 6 is engineered so that all conductors work together to carry the signal successfully. They're not just simple conductors like telephone wire, and that's why you need Cat 5e and not telephone wire for Ethernet. The insulation properties can remain intact and the wire can still conduct electricity, but the cable can be invisibly damaged in terms of its high speed characteristics such as crosstalk prevention. Look up the specifications on your wire's minimum bend radius and maximum pull tension. Pinching the cable bundle too tight could cause a problem with operating at gigabit speeds, but it might work fine at 10MHz speeds.

I also consider myself "above average" in my ability to spot fake reviews and reviewers, and I dig deeper into search engine results than most people. I visit various kinds of sites before making a major purchase, sites that marketers aren't necessarily targeting today. I'm assuming (a very big assumption based on the one sample of "me") that people in my group are better at spotting planted reviews and identifying rigged search results.

    I'm making another big assumption here, but I'm expecting that a significant fraction of people in my demographic who also make decisions in this way are also aware of NoScript, and are employing anti-tracking defenses. If both of these assumptions are true, fewer of the NoScript users are revealing their excellent sleuthing abilities to the analysis firms. That means my demographic's anti-SEO-trickery and anti-planted-review skills are being revealed to the marketers at a slower rate.

    Not quite. NoScript provides for the transparent absence of most third party trackers. Its users are really in "the blind spot" of these firms, as nobody is gathering complete metrics on their surfing habits. They can't.

    You may want to assume that NoScript users behave in the same way as non-NoScript users in the same demographic, but you can't be sure. After all, most NoScript users are concerned about their privacy or dislike intrusive advertising, and are self-selected people who better understand browsers and technology. This places them in their own demographic. The average NoScript user is further along the educated axis, which generally translates to people with higher wages and more disposable income. It includes early adopters, technology trendsetters, family experts, business technical experts, etc. These are desirable customers, the exact sort of people they'd love to influence with marketing.

    And what kind of things are they missing out on? They want to know where technically literate people go for information before making a purchase. Do they visit epinons, ConsumerReports, eBay, Google shopping, or Amazon reviews? Other sites? All of the above? Do they stick to the first page of Google results? Do they trust Amazon reviewers more than NewEgg reviewers? Do they prefer to shop by price, or to buy from retailers with higher reputations? That's information you can't get by looking at a single retailer's results. If you don't know how they got there, you don't know what factors to influence to get others to show up.

    Ultimately the marketers are trying to understand what kinds of astroturfing they can get away with. NoScript makes their job much harder. And as long as they can't identify my abilities to spot SEO trickery, planted reviews, etc., it means I personally get results that are somewhat more honest to me, and are less biased by the marketing firms.
