  1. Keeping images in your head. on An Eye-Scanning Lie Detector Is Forging a Dystopian Future (wired.com) · · Score: 3, Interesting

    From noted experts on lie detectors and their weaknesses: Yes, they are measuring your current emotional/visceral response. Pathological liars do very well on these as they are acting out their stories (true or not); as they experience the universe of the story, it becomes their reality and their bodies react accordingly.

    Okay, you aren't a pathological liar. Can you focus on images, at least? You want a positive emotional response? Focus your mind on sex while answering a question. You'll inhale, your pupils will dilate, skin thermal and electrical properties will change. For an opposite reaction, focus on maggots on an open wound on your arm.

  2. Re:Once upon a time on Amazon is Stuffing Its Search Results Pages With Ads (recode.net) · · Score: 3, Insightful

    When you go into the store, you see a lot of items on endcaps of the aisles. They are highly visible. You see items on shelves at eye level and other items that are shelved high up or at the floor.

    Why do you think some items are on endcaps, and some are shelved at eye-level as opposed to floor-level? That's right. Companies PAY to have their products placed at more desirable locations.

    As you were saying, ads, ads, ads, ads, ads.

  3. Correction to TI timings. on This is the Story of the 1970s Great Calculator Race (twitter.com) · · Score: 3, Informative

    TI introduced their SR-10 calculator in 1972, not 1975. I bought one in 1973. It could do SQUARE and SQUARE ROOT in addition to the four basic functions, for around $100. A marvel!

    They released the SR-50 calculator, full trig-log capable, in 1974. I replaced my SR-10 with one of these before going off to college.

    Nope. I had an SR-10 (1973) and an SR-50 (1974). I don't know where the SR-50 is, but the SR-10 STILL WORKS!

    I went to a technical school (RPI) with the ongoing battle between RPN and algebraic notation (HP vs. TI). I knew a lot of people that had both, and both families lasted very nicely under heavily used conditions.

  5. Let Apple appraise their own buildings - YES! on Apple Argued That Buildings at Its Headquarters Were Worth $200, Not $1B, To Reduce Its Tax Bill: Report (sfchronicle.com) · · Score: 1

    Someone once proposed letting companies and people appraise their own buildings and houses for tax purposes.

    The caveat is that this appraisal is now a for-sale price. If Apple appraised their HQ at $200 and I walked in with a pair of Franklins, I now own the building.

  9. An example of cognitive bias. on Child Psychotherapist: Easy and Constant Access To the Internet Is Harming Kids · · Score: 2

    Cognitive bias is a self-deceptive practice in which a person (unintentionally) selects data to support his or her hypothesis. Understanding this principle is central to the critical analysis of scientific research. Is the person influenced by what they are seeing (due to their position, etc) when seeing a subset of the universe? Is the person drawing conclusions, abstracting from the subset to the whole, without realizing that the subset is not a representative one?

    There are many issues for concern when reviewing this article. First, Dr. Evans is embedded in a nonrepresentative world, is seeing two changes (increased cellphone use and increased identification of issues within children), and is stating a correlation on factors that may well be coincident. Second, there is the issue of the definition of mental illness in children. For autism (a general example, not one of mental illness), the definition and boundaries have shifted over time. This has been one of the causes of the increased incidence of autism. I will hypothesize that the definitions and boundaries of "mental illness" in children has also changed over time, and this may well be a critical factor in the increased incidence of the same.

    Dr. Evans proposes an interesting hypothesis (and one we have heard before). But the evidence quoted in the article is circumstantial at best, consisting of anecdotes. She does not quote any general studies. She focuses solely on the negative aspects of a changing environment, without quoting on the positive. Without baselining the definition of "mental illness", without a complete and neutral analysis of the overall impact of the *change* (both positive and negative), Dr. Evans's proposal is at best a weakly supported hypothesis.

  10. Gameplay? Story? on Gabe Newell Understands Half-Life Fans, Not Promising Any Sequels · · Score: 2

    There is gameplay and there is story. There is story and there is art. There is business and profit and legacy.

    Why do we want HL2E3? It isn't gameplay (for the most part). We can get that anywhere. Do you pull out HL2E1 or HL2E2 (or even Black Mesa) every now and then? Yeah. It is story. It is borderline art (though my artist-wife would guffaw to read that).

    Story, give us story. If no one is interested in completing it, is it because no one is interested in the story, or because no one is interested in extending the gameplay? Would it be a fulfilling experience to take their existing framework, give it to new devs as an experimental/toy playground and treat it as a "have fun" environment? Would they be able to entice a team into a non-profit-driven, do-it-for-the-fan-accolades pro bono/cover the cost experience?

    Do it, Gabe. How you sell it internally ("another game release in our catalog" vs. "art and glory for the ages") HIGHLY influences how it appears to potential team members. You can sell product outside, I'm sure you can sell it inside as well.

  11. Re:Interesting on Hotel Group Asks FCC For Permission To Block Some Outside Wi-Fi · · Score: 1
    You obviously have never traveled on business. Most business travel for most of the business travelers I know works like this:
    • Pick a hotel chain that has points and is within the company's budget (that is, how much you can bill to the client).
    • Stick with that hotel chain forever and accumulate points to your personal account.
    • Use the points for your vacations.

    We bill out the cost for our consultants. As long as the client is paying and it is within the contract budget, everyone is happy. And all of the hotels cost about the same, kind of like all of the gas stations at a corner costing the same. For company-supported travel, we establish a budget (yes, we are reasonable, we like to keep our employees happy) and go from there.

  15. Re:Almost as retarded as patenting 2 primes ! on Zazzle.com Thinks Depictions of Pi Are Protected Intellectual Property · · Score: 4, Informative

    Did you seriously read the patent? The patent is using the numbers in one of the claims as part of a mechanism. Schalfly is not patenting the numbers, just their use in a particular process. He is patenting the process, which involves using a designated set of primes to perform iterative calculations to compute "partial modular reduction of cryptographic variables."

    The concept (using a designated something as a component in a patented invention) was the same in patent number 1. In this patent, gears and cogs were used to improve the efficiency of locomotives going up hills. What was patented was using gears and cogs in a particular configuration to accomplish a goal. Gears and cogs were not patented. The construction was patented.

    The same thing here. The primes are not patented. You are free to use them however you want, as long as you do not use them in this particular machine to compute "partial reduciton[s] of cryptographic variables." Go ahead, use them as seeds in the dice roll generator for your RPG. Use them as dimensions of your mansion's living room. Print them out and use the paper to light a fire. You're allowed.

    I can't tell you HOW MANY TIMES I've run into people who think they know how to build a system because they know a tool. And they are fine, until I ask them about timing and randomness, data complexity, parallelizing on a massive scale, and so on.

I've also gotten it running on a pair of DLink DNS-323 boxes (yes, also RAID-1'ed).

  23. What makes a good manager? on Do Non-Technical Managers Add Value? · · Score: 2

    A good manager keeps invasive outsiders away and makes sure that the workers have what they need.

    Bidirectionally, this means understanding (of the needs of each group) and communication (both listening and answering). To the outsider, this means understanding their issues and communicating meaningful replies in terms they understand. It means making appropriate requests and supporting the requests using concepts that the outsiders understand. To the insider, this means understanding their needs and being able to re-frame them in a business sense (for the outsider). It means being able to answer why the insider can't have everything. It means being able to explain business needs and how the technology can meet it. Within the team, it means managing the dynamics of the group without being a babysitter or kindergarten teacher.

    A business-oriented person who understands the implications of the technology can make as good a manager as a technical person with a strong understanding of the business needs. The most critical factor is the ability to translate and communicate.

  24. TSA-quality thinking on Member of President Obama's NSA Panel Recommends Increased Data Collection · · Score: 2

    This is exactly the level of thinking the TSA uses to design its so-called security protocols. Figure out what was done. Design something that looks like you are looking at it. Then do it.

    Meanwhile, terrorists move ahead to different protocols, different targets. Such as (as has been written), using Google Mail and cross-editing mail drafts to pass information. The drafts are never sent. They are an ongoing, live document. Let me repeat, the drafts are never sent. No emails are generated.

    So all that we are left with is a bloated, monstrous governmental organization that monitors the citizenry but not the terrorists. And justifies its own existence and growing expense.

    Life by fear.

  25. Data caps aren't about data caps on Top US Lobbyist Wants Broadband Data Caps · · Score: 2
    Data caps are about charging for what is popular.

    No company has ever really demonstrated a shortage of cell phone minutes, text bandwidth, connection count, data [bandwidth latency voluume]. The companies have only demonstrated a need to maximize revenue based upon what was in vogue.

    In the early cell phone days, it was "minutes". Suddenly, minutes became cheap to unlimited (especially as a marketing tool: "friends and family", etc.) and we moved to extensive charge-by-the-text-message. Now, phones are more versatile as data engines (pictures, streaming music/video, GPS, etc.) and we are offered unlimited text and voice, with caps on the things we use the most. Excuse me, extensive charges.

    Mostly in the major providers. At the same time they boast of the best and fastest and most capable networks. "We have the most but you can't use it."

    Same thing with the home data providers (internet providers). Capacity grows beyond use, perceived need/use increases, and now we are seeing the two financial vampires appear: data caps and bandwidth limitations (no network neutrality).

    There is no shortage. This is not a supply-and-demand curve model. This is a monopoly-and-demand model. With limited suppliers acting in an unstated collusion, we have the movement towards pricing models that focus on today's usage patterns. "Last year we drummed up the demand by offering unlimited data, now you want it so we're going to create an artificial scarcity and charge you for it."

    Sadly, as monopolistic as these services are, they are not treated as utilities. They should be. A quarter-century ago they were a nicety. Now they are an essential part of the functioning/growing society/economy, and should be treated accordingly. Doing so would increase stability, access, and overall functionality.
