  1. Best language for scientific/numerical work? on ESR Sees Three Viable Alternatives To C (ibiblio.org) · · Score: 2

    I looked into Python for scientific/numeric programming, and from what I gather, key value paired lists are at its foundation and everything, including its object class model, is layered on top of that. Java, on the other hand, is based on an object class model from which you construct data structure objects such as key value paired hash lists?

    What I like about Java is that it supports dense arrays of numeric values. Its dense-array model is an exception to "everything is a" hash list/object/thingy. It appeared to me that Python implements arrays on top of key value paired lists/hash lists/dictionaries/whatever-you-want-to-call-them. Maybe that works for sparse-array numeric linear algebra, but much numerical programming involves operations on dense numerical arrays where compilers optimize array access in loops to incrementing address registers. Even in Java, which does not allow disabling this safety feature, the compiler will analyze loops to optimize bounds checking.

    Python has NumPy to support dense arrays of numeric values in this fashion, but NumPy, at least at the time 10 years ago I looked at it, was this wart on the Python language, in other words, something that sticks out and gives the appearance that it doesn't really belong there. It is straightforward to operate on NumPy arrays in native-code extension modules to Python, but on the Python side, such an array is this "blob" that you can only poke at with native-function calls.

    Matlab is the "thing", the expensive, proprietary thing that persons with engineering domain knowledge who cannot be bothered to learn a "real" programming language use. It is for the people who used to use Fortran to perform engineering calculations with one of those Tektronix "vector storage" video displays 40 years ago and now they have Matlab, which combines a goofy scripting language with a GUI with a vast legacy Fortran and C numerical library with a graphical visualization library.

    Forget about Matlab; I run Java as my "FORTRAN" in Eclipse and my Java programs output tab-separated columns of numeric data. Java does not have an "immediate mode eval-prompt" like the Matlab command windows, but the incremental syntax checking and compiling allows for much faster edit-build-execute cycles that what Visual Studio offers with C/C++. If my program crashes, I can quickly find the offending line in the Eclipse edit window -- good luck with that in C/C++. The Eclipse console window is a text-mode GUI allowing data exchange with other GUIs -- C++ in Visual Studio does not support such data exchange of numeric console-mode output. My "Tektronix vector storage display" is copy-and-paste to an Excel or Open Office Calc spreadsheet to plot the results.

    In my ideal world, there would be 3 layers, scripting/incrementally compiled managed-code/native code. I would like something other than the serious-coin-per-seat sole-source Matlab as the scripting layer (it interfaces well with Java with transparent exchange of dense arrays, in fact, the Matlab GUI is written in Java), but I really like Java for that middle layer.

  2. on the Engineering Quadrangle, Google had students queued up to get a donut along with a chance to win a Google Donut or whatever they call their clone of the Amazon Echo. They were totally slow because you had to give over your personal information to even get the kind of donut you could eat, and they had this Disney-ride line-control labyrinth filled with students by 8:30 AM. Sure wish I had my camera to photograph Google treating a large mob of Engineering students like cattle in a feedlot.

    What did this have to do with the mission of the College of Engineering?

  3. Since Mr. Torvald's kernel was the enabling contribution, I propose calling it "Linux-GNU."

  4. I had thought that Mr. Damore posted to an internal Google message board where employees were encouraged to post their views on the diversity policy?

    If he had posted publically in his role as a Google employee, I would concur with the sobriquet "dumbass."

    Had he on his own initiative circulated an "you are entitled to reading my opinion" memo within Google, also "dumbass."

    Since he responded to an internal Google request to carry on a conversation on a potentially controversial company policy . . . wait, "conversation" doesn't mean having a back-and-forth exchange of views, "conversation" means the company speaks with one voice and the employee politely listens. This is a widely known social convention, this is not by everyone in the world apart from maybe a 'spergie coder. Never mind, "dumbass"!

  6. Alec Baldwin on Newspaper Obtains James Damore's Complaint Against Google (siliconbeat.com) · · Score: 3, Interesting

    Hollywood actor Alec Baldwin comments on an impresario in the news for allegations, which the subject of these allegatiions has as much as admitted, that he had assaulted many women. Mr. Baldwin remarks on Twitter or other public places that "everyone knew" what was going on but said impresario was not held to account because "women accepted settlements."

    The response to Mr. Baldwin was yes, women accepted financial settlements in exchange for their silence but what choice did they have given how the "system is rigged"? Excellent point, and there is also a "you go first" problem. Once many women come forward with corroborated stories, it is not anywhere near as hard as if you are the first woman to come forward against a well-connected man and how you as the accuser are going to be put on trial.

    But that is not how the correct-thinking persons are responding to the once correct-thinking Alec Baldwin. There is not a conversation of the form, "This wouldn't have been such a problem if the women hadn't accepted financial settlements" to which the response could be offered, "Yes, I see your point that maintaining silence perpetuates the problem. But you also have to take into account that the first woman to speak out will be facing tremendous obstacles, especially not knowing if other women will follow in speaking out."

    No, Mr. Baldwin offers his opinion and then it is, "Oh the Humanity! How can Baldwin make such a sexist, insensitive remark? Alec Baldwin is the worst sort of man in Hollywood with no regard for what women in Hollywood go through! Mr. Baldwin's career is finished."

    The subject here is a somewhat different aspect of men's inhumanity to women, but do not many of the "debunkings" of James Damore, here and elsewhere, fit this pattern?

  8. "Devil's Advocate" in Elon's cannonization hearing on Tesla Posts Biggest Quarterly Loss, Slashes Production of Model X and Model S (yahoo.com) · · Score: 1

    Sometimes you need what the Vatican called a "Devil's advocate" when considering whether to venerate person as a saint.

    Heaven knows that the late Christopher Hitchens was "one step above a stalker" of Anjezë Bojaxhiu https://en.wikipedia.org/wiki/....

    On the other hand, Mother Teresa became an object of unquestioning cult veneration while living and after her passing. Her personal sacrifice, her willingness to work with the sickest of the sick among the poorest of the poor, what saintliness. "Mother Teresa" becomes a throw-away line in a Sunday sermon.

    Maybe, just maybe, this saintly lady had her own obsessions. She was running a hospice, after all, but maybe her practice could have made better use of pain-relief medication rather than having end-stage cancer patients in agony, telling them that their suffering is a virtuous imitation of Christ?

    So why do I "believe" the godless Mr. Hitchens instead of Catholic Christian believers regarding Mother Teresa? Maybe I have heard many accounts as well as experienced for myself where belief becomes an ideology not properly tempered by common sense? Don't tell that patient that their indescribable pain is making them go to Heaven, give them some morphine, please! Yes, Mr. Hitchens may have been crazy to doubt Mother Teresa's goodness, but there is that trope that crazy people sometimes utter truths, not just that, warnings one ought to heed.

    So what is so wrong about "making her a saint." For all of Hitch's knocks, Mother Teresa is in Heaven for all I am able to know and for all I am permitted to judge. On the other hand, the rush-to-sainthood on her, in light of suppressing her human frailties, weakens the moral authority of the Vatican with respect to its role in steering others towards becoming unheralded saints. I am told the Vatican cut corners in this process (like Elon getting his Model 3 line running?) by leaving out the Devil's advocate.

    OK, I have played out the analogy of Missionaries of Charities to a car, but one can get the idea. Father Elon is shepherding us towards our de-carbonized transportation Future, but there is an Amen Corner of supporters who cannot admit to any of his shortcomings. Do you think that the Niedermeyers (and Hitchens) are doing a service in that their absence, there will be no questioning taking place?

    It is an odd thing for Ayn Rand disciples with the empathy for workers of the fictional Gordon Gecko to be so stoked to tell us "Nothing to see here, move along" about Tesla. Usually those in the free-market-uber-alles faction are just not that impressed by electric cars. A person has to wonder if a Slashdot faction commenting on this story has an "agenda."

    It is also an odd thing that Honda and other multi-national automakers have been able to set up non-union shops here in the U.S. without engaging in across-the-board purges in a way to get the UAW to smell blood.

    Talking about blood, Jean-Louis Gassee, who has a chronic medical condition requiring frequent testing of his own blood, had some interesting insights as to why tech wunderkind Elizabeth Holmes and the Theranos blood-testing company seemed odd. More recently he blogged about visiting the Fremont plant as a celebrity Model S purchaser and how he rubbed his Tesla-enthusiastic fellow celebrities the wrong way with his remarks (Gassee was buying a Model S for his wife, he explains). Parts were stacked high in contradiction of Lean Manufacturing dogma, and in contrast with the Maryville, Ohio Honda plant he had observed, the Tesla shop floor activity was frenetic. The Honda plant, by contrast, had its assembly line running so smoothly that the workers did not appear to be breaking a sweat.

    The Tesla Model S is an incredible automobile, they tell me, and maybe the problem with it is that it is incredible that Tesla is able to sell an automobile of that sophistication for the price they charge without it all being smoke-and-mirrors of burning out its workers and fleecing its investors to contribute the labor and money to in effect give away what are effectively hand-built quarter million-dollar cars?

    The stories of 70-hour work weeks of relentless pressure are just sour grapes from slackers who deserved to be cut loose? And what about SpaceX, the darling of the Ayn Rand space cadets, where Musk is able to work miracles launching reusable rockets for low money while the Boeing and Rocketdyne or whoever are spinning their fins attempting to build a new rocket, using armies of slacker aerospace workers who just put in their time and then go home to watch their daughters' soccer games, whereas SpaceX has a cadre of enthusiastic non-slacking workers putting in the 70-hour work weeks of the Apollo era where everyone ended up divorced?

    Back at Tesla, they are trying to speed up their line ten-fold to go from the high-end luxury market of the S to the upper-mass market sedan market of the Model 3. And there are just some "bottlenecks" to be worked out? While their "body" line tooling is still being put together in some undisclosed location in Southeast Michigan?

    So everything is fine with everything Elon, and he is going to work out these snags like he has worked out every engineering problem he has faced before because he is a Genius, the bitching about these recent dismissals is just a distraction. OK.

He expressed the hope that through NAFTA and future agreements that the economy of Mexico could develop to the point that free migration was tenable, and he pointed to how Spain improved economically to become closer to the level of Germany to allow visa-free movement of people between Spain and Germany.

    Well good. Especially since many people under those circumstances are here, raised and indoctrinated in our shared American since early childhood. They are here because immigration laws were not adequately enforced, creating de facto Open Borders.

    OK then, we offer work permits and legitimate Social Security Numbers and amnesty to those here under those circumstances.
