  1. oh boy here we go again on Using Drupal · · Score: 1

    Drupal is software written by amateurs--oh, they are well-meaning and their sheer numbers swamps the efforts of most other projects, making it a powerful temptation for the get-it-done-now. But Drupal is terribly convoluted, inefficient, buggy and expensive (it is impossible to deploy a Drupal site without an admin on retainer to apply the numerous security updates)--its arcane architecture was written to accomodate the quirks of the non-object oriented and now-obsolete PHP4--its a bandwagon with a long and painful upgrade path that will probably take the next 10 years to sort out. Have fun jumping on it. (FYI I am fully on that particular wagon though I'm not particularly enthralled, obviously).

  2. Re:R sucks as a language on The Power of the R Programming Language · · Score: 1

    Mathematica also supports this notion of unevaluated inputs. For example, Plot[] does this and then internally compiles an optimized version of the input expression for faster repeated evaluation that leverages the requested precision goal (usually machine precision which is fastest).

    Usually Evaluate[]/Unevaluated[] works nicely and is transparent to the end user but when it it doesn't work right for a particular use, it leads to some highly confusing code.

    Calling people "Idiots" is 1) not helpful for others and 2) only encourages aggravation in yourself. Its counterproductive in every way. Selfishness and altruism are both fine qualities, they can co-exist, and will get you far in life. Being a zealot won't get you anything.

    People are naive, stubborn, uneducated and manipulated. But all of those are qualities that can be changed--they are not idiots.

    No its not obvious... supply and demand economics, right? Well, the demand is high, but the supply is essentially infinite as TFA points out. N/infinity = zero for extremely large values of N. Therefore it should be practically free. What we are looking at is a price-fixing scam.

    USB hasn't changed the approach towards class compliance, and they continue to improve those related specifications. If you want to point fingers, look at the hardware and software vendors. FTDI, for example, makes a nearly ubiquitous USB-serial chip that is not class compliance in spite of the fact that every major OS supports the serial device class.

  7. Re:latency badness on Intel Developers Demo USB 3.0 Throughput On Linux · · Score: 1

    The quantization error is a technical shortcoming of MIDI, not USB. Open Sound Control uses time stamps that allow the messages to be reconstructed with the original time structure after transmission over a transport with arbitrary quantization (and random delay).

    That isn't correct--USB also has an isochronous transport mode that guarantees timely access and bandwidth to a streaming device.

    Also there is USB On-The-Go (OTG) which is for ad-hoc point-to-point communication between devices without a host controller. That was released as a 2.0 spec supplemental and is commonly found in ... printers that you can plug your camera into, for example.

    The idiocy of the US is the fault of the EPA which continues to use the misleading MPG rating for fuel economy. Given how bad our educational system is, its not reasonable to expect consumers to re-do the math themselves.

    Loss of life, yes, some. World wide economic problems, no, not even close... in fact its been mostly ignored for several years because the actual cost in terms of pirate ransoms is trivial compared to the basic operations revenue and profit margins of a major global shipping company. In fact the only thing that is really expensive is the payout to families when people get killed--and the pirates know this--their goal is to get money without making a big scene.

    Its a basic fact that impoverished regions of the world breed terrorists, drugs, piracy, human rights abuse and other crimes. Somalia and areas of Afganistan/Pakistan being a couple of the worst, ... the sooner the G8 (and especially the US) come to senses and realize this, the better.

    The trick to that sort of optimization is to defer the evaluation until the =, at which point the optimal execution plan is selected. But, you can't overload "=" in C++. The workaround is basically to provide another function to explicitly force the evaluation when you need it.

    The problems with the justice system are related to insufficient accountability and transparency of information and economic barriers that deny ordinary citizens sufficient resources to receive a fair trial against opponents with wealth and/or power, including the state, large corporations and the ultra-wealthy.

  16. Re:Misleading summary on Unix Dict/grep Solves Left-Side-of-Keyboard Puzzle · · Score: 1

    The OED doesn't list every valid word construction as its own entry--often one has to look up a more basic form to find the definition. Anyways, here is what I got:

    "after-" is listed as an "in combination" with broad usage, though usually with a hyphen for syntactic clarity. If we want to be pedantic, "after-cataract" is probably more correct.

    "vertebrated" is an adjective for something having or suggesting the appearance of vertebrae. Devertebrated isn't explicitly mentioned but it seems a reasonable construction.

    "tessera-": another "in combination" prefix meaning "four", derived from Greek. "tesseradecade" is a group of fourteen.

  23. Re:Muscle Cramps? on Stretching Before Exercising Weakens Muscles · · Score: 1

    Light aerobic workout will prevent cramping just as well in addition to reducing joint friction. And stretching doesn't prevent overextension, it encourages it.

  24. Re:Importance of warm-up on Stretching Before Exercising Weakens Muscles · · Score: 1

    For the purpose of training the muscle fiber to relax, passive extension is both more effective and considerably less damaging than any active stretch.

    To be clear, a passive extension puts the muscle at full extension, but without additional tension, and also with the limb in a fully-supported non-weight bearing position (typically this requires the floor or some other support).

    Light active stretching can help with optimizing the alignment of the muscle fibers, but it shouldn't be done pre-workout, and it can actually antagonize the relaxation of the muscle since as one approaches the extension limit of the muscle a protective reflex causes the muscle to tense up.

    One more point to make is that flexibility is controlled in part by a genetic factor that influences tenacity of the collagen. The technical term is "hypermobility" and is a serious problem for some people, who are often found in fields where natural flexibility is an advantage (dancers and others in the movement arts). Hypermobile individuals are prone to joint injury because they don't have a sufficiently tight muscular cage around the joints. Stretching can greatly increase the likelyhood of injury. Light to moderate aerobic workouts will reduce the probability of injury for two reasons: 1) proper penatration of synovial fluid to all regions of the joints, and 2) increased blood pressure improves muscular stability around the joints.

    Nothing against you in particular but I have yet to meet any athletics instructor that actually studied kinesiology to any technical extent, especially in martial arts. I would trust the advice of a sports medicine physical therapist--that is a medical degree with a relevant emphasis (general practice doctors also don't typically have sufficient knowledge). The Pilates certification is also reasonably technical, and I have yet to see any Pilates instructor recommend something questionable. The advice of nearly everyone else is derived from hearsay and anecdotal observation.

  25. Re:Importance of warm-up on Stretching Before Exercising Weakens Muscles · · Score: 1

    That isn't entirely true, since for some muscle groups it is most important to strengthen it in the extended state because that is its "normal" mode. The abdominals in particular.
