'Calculators Killed the Standard Statistical Table' (sas.com)
theodp writes: In an obituary of sorts for the standard probability tables that were once ubiquitous in introductory statistics textbooks, Rick Wicklin writes: "In my first probability and statistics course, I constantly referenced the 23 statistical tables (which occupied 44 pages!) in the appendix of my undergraduate textbook. Any time I needed to compute a probability or test a hypothesis, I would flip to a table of probabilities for the normal, t, chi-square, or F distribution and use it to compute a probability (area) or quantile (critical value). If the value I needed wasn't tabulated, I had to manually perform linear interpolation from two tabulated values. I had no choice: my calculator did not have support for these advanced functions. In contrast, kids today have it easy! When my son took AP statistics in high school, his handheld calculator (a TI-84, which costs about $100) could compute the PDF, CDF, and quantiles of all the important probability distributions. Consequently, his textbook did not include an appendix of statistical tables." -
SAS Mocked For Recommending 60% Proprietary Software, 40% Open Source (infoworld.com)
This week SAS wrote that open source technology "has its own, often unexpected costs," recommending organizations maintain a balance of 60% proprietary software to 40% open software. An anonymous reader quotes InfoWorld: How they arrived at this bizarre conclusion is hard to fathom, except that SAS sells more than $1 billion worth of proprietary software every year and presumably would like to continue, despite a clear trend toward open-source-powered analytics... In a Burtch Works survey of over 1,100 quant pros, 61.3% prefer open source R or Python to SAS, and only 38.6% opting for SAS, with that percentage growing for open source options every year.
Worse for SAS, a variety of open source data infrastructure and analytics tools threaten to encroach on its bastions in data management, business intelligence, and analytics... Nearly all innovation in data infrastructure is happening in open source, not proprietary software. That's a tide SAS can try to fight with white papers, but it would do better to join by embracing open source in its product suite.
"In the paper, SAS correctly argues that open source versus proprietary software is not an either/or decision..." writes InfoWorld, but they note that the report also "put the percentage of open source adopters at a mere 25%, which is pathetically wrong." The article suggests a hope that the report "is the product of a rogue field marketing team, and not the company's official position." Adobe's vice president of mobile commented on Twitter, "I just wonder who in their marketing dept thought this was a good idea." -
Ask Slashdot: When Do You Include 'Unnecessary' Code? (sas.com)
"For more than 20 years I've been putting semicolons at the end of programming statements in SAS, C/C++, and Java/Javascript," writes Rick Wicklin, a researcher in computational statistics at SAS. "But lately I've been working in a computer language that does not require semicolons. Nevertheless... I catch myself typing unnecessary semicolons out of habit," he writes, while at other times "I include optional statements in my programs for clarity, readability, or to practice defensive programming." While Wicklin's post is geared towards SAS programming, Slashdot reader theodp writes that the question is a language-agnostic one: ...when to include technically-unnecessary code -- e.g., variable declarations, superfluous punctuation, block constructs for single statements, values for optional parameters that are the defaults, debugging/validation statements, non-critical error handling, explicitly destroying objects that would otherwise be deleted on exit, labeled NEXT statements, full qualification of objects/methods, unneeded code from templates...
He's wondering if other Slashdot readers have trouble tolerating their co-workers' unnecessary codes choices (which he demonstrates with a video clip from Silicon Valley). So leave your answers in the comments. When do you do include 'unnecessary' code in your programs -- and why? -
Symbolic vs. Mnemonic Relational Operators: Is "GT" Greater Than ">"?
theodp writes: "Mnemonic operators," writes SAS's Rick Wicklin as he weighs the pros-and-cons of Symbolic Versus Mnemonic Logical Operators, "tend to appear in older languages like FORTRAN, whereas symbolic operators are common in more recent languages like C/C++, although some relatively recent scripting languages like Perl, PHP, and Windows PowerShell also support mnemonic operators. SAS software has supported both operators in the DATA step since the very earliest days, but the SAS/IML language, which is more mathematically oriented, supports only the symbolic operators. Functionally, the operators are equivalent, so which ones you use is largely a matter of personal preference. Since consistency and standards are essential when writing computer programming, which operators should you choose?" -
Calling All Data Do-Gooders
theodp writes: We're entering a new era of data-for-good, writes SAS CEO Jim Goodnight, who explains how SAS and the International Organization for Migration are using analytics and data for disaster relief efforts, but issues a broader call-to-action: "These projects just scratch the surface of what's possible when new data, and those that know how to use it, are applied to humanitarian needs. Organizations such as DataKind and INFORMS, through its new Pro Bono Analytics program, are rallying data scientists to lend their time and expertise to helping people around the world. And there are many more data sets out there that could help with relief and other humanitarian efforts. It's an exciting time to be in the world of big data and analytics. We're just beginning to understand how technology can tackle society's grand challenges." Please share your ideas on what unlikely data sources might help with disaster relief. And, how can we bring the world's analytics talent to bear on these challenges. -
Turning a Nail Polish Disaster Into a Teachable Math Moment
theodp writes: In The Spiral of Splatter, SAS's Rick Wicklin writes that his daughter's nail polish spill may have created quite a mess, but at least it presented a teachable math moment: "'Daddy, help! Help me! Come quick!' I heard my daughter's screams from the upstairs bathroom and bounded up the stairs two at a time. Was she hurt? Bleeding? Was the toilet overflowing? When I arrived in the doorway, she pointed at the wall and at the floor. The wall was splattered with black nail polish. On the floor laid a broken bottle in an expanding pool of black ooze. 'It slipped,' she sobbed. As a parent, I know that there are times when I should not raise my voice. I knew intellectually that this was one of those times. But staring at that wall, seeing what I was seeing, I could not prevent myself from yelling. 'Oh my goodness!' I exclaimed. 'Is that a logarithmic spiral?'" So, got any memorable teachable math moments you've experienced either as a kid or adult? Yes, Cheerios Math counts! -
How Blind Programmers Write Code
theodp writes: Yes, folks, there are blind programmers. There's Ed Summers, for one, who lost his vision at age 30 and now ghostblogs for Willie the Seeing Eye Dog. And if you've ever wondered how the blind can code, Florian Beijers, who has been blind since birth, explains that all he needs is a normal Dell Inspiron 15r SE notebook and his trusty open source NVDA screen reader software, and he's good-to-go. "This is really all the adaptation a blind computer user needs," Beijers adds, but he does ask one small favor: "If you're writing the next big application, with a stunning UI and a great workflow, I humbly ask you to consider accessibility as part of the equation. In this day and age, there's really no reason not to use the UI toolkits available." -
How To Fix The Shortage of K-5 Scholastic Chess Facilitators
theodp writes The good news, writes Michael Thomas, is that wired kids are learning chess at an unprecedented rate. Young children learning chess from tablets can quickly become more knowledgeable than their parents. But the bad news, laments Thomas, is there is so much demand for scholastic chess that there are not enough experienced chess facilitators to go around. Could technology like RFID-tagged chess pieces or services like ChessStream.com be employed to referee second-grader chess matches, Thomas wonders, or are more well-meaning-but-not-necessarily-expert human facilitators — a la T-ball coaches — the answer? -
Ask Slashdot: Where's the Most Unusual Place You've Written a Program From?
theodp writes: "Michael Raithel was polling the SAS crowd, but it'd be interesting to hear the answers to the programming questions he posed from a broader audience: 1. What is the most unusual location you have written a program from? 2. What is the most unusual circumstance under which you have written a program? 3. What is the most unusual computing platform that you wrote a program from? 4. What is the most unusual application program that you wrote?" -
The Desktop Is Dead, Long Live the Desktop!
theodp writes "'The desktop or laptop is now in decline,' writes John Sall, 'squeezed from one side by mobile platforms and from the other side by the cloud. As a developer of desktop software [by choice not necessity], I believe it is time to address the challenges to our viability. Is software for the desktop PC now the living dead, or zombieware.' While conceding there's some truth to truisms about the death of the desktop, Sall believes there's still life in the old desktop dog, 'We live in a world of computing where dreams come true,' Sall concludes. 'The mainframe bows to the minicomputer. The minicomputer bows to the personal computer. The personal computer bows to the tablet and smart phone. It seems as if these will soon bow to the smart watch or smart glasses. But at each step along the way, some applications find their best home – and other applications as well as new applications find the more convenient and smaller home better...So let's keep our desktops and laptops, our PCs and Macs. They are amazingly good at what they do.'" -
Why Letting Your Insurance Company Monitor How You Drive Can Be a Good Thing
Hugh Pickens DOT Com writes "Kim Gittleson reports at BBC that car insurance firms like Progressive are trying to convince consumers that letting them monitor their driving behavior is actually a good thing. They say that the future of car insurance is not just being able to monitor individual drivers to give them lower prices, but also to make them better drivers. 'Now that we can observe directly how people drive, we think this will change the way insurance works,' says Dave Pratt, who says that Progressive has more than a trillion seconds of driving data from 1.6 million customers. '18-year-old guys pay a lot for insurance, but some 18-year-olds are really safe drivers and they deserve a better deal.' Better big data technologies, like the telematic driving data collected by car companies (PDF) or even information gathered from social media profiles, can help augment that risk profile. 'If I'm a driver that doesn't drive that frequently, and I have a pattern that would indicate that I drive more carefully than an average person with my profile, then I may be able to save 30-40% on my car insurance, and that's pretty significant,' says Joe Reifel. For now, using big data analytics for insurers is still in the early stages. Only 2% of the U.S. car insurance market offers an insurance product based on monitoring driving, but that proportion is projected to grow to around 10-15% of the market by 2017. And other countries, like Italy and the U.K., are already using the data to analyze not just risk profiles but also to determine who is at fault in car accidents. The future, most analysts agree is create a continuous feedback loop between insurers and consumers, so that consumers will react to the big data analyses that insurers perform and change their behavior accordingly. 'Bad drivers will at some point need to improve their driving or accept [having] to pay for the real risk they represent,' says Jacques Amselem." -
Are You Too Good For Code Reviews?
theodp writes "Why do some programmers,' asks Chris Hemedinger, 'place little value on code reviews?' This apparently includes even Programming Greats like Ken 'C' Thompson, who quipped, 'we were all pretty good coders' when asked about the importance of code reviews in his work. Hemedinger, on the other hand, subscribes to the school of thought that peer code reviews are Things Everyone Should Do. Not only do reviews keep you on your toes, Hemedinger says, they also 'improve quality, ensure continuity, and keep it fresh. Who can argue against that?'" -
SAS Named Best Company To Work For In 2010
theodp writes "If you're in the market for a new job, Fortune has just published its list of 100 Best Companies to Work For in 2010. Topping the list this year is SAS (SAS jobs), the largest privately held software company, which Fortune notes is populated with more statisticians than engineers or MBAs, and led by a Ph.D. founder whose first love is programming. Google (jobs), which once viewed SAS as model for employee perks, took the #4 spot, and Microsoft (jobs) checked in at #51." -
Who Wants To Be a Billionaire Coder?
theodp writes "Computerworld reports that 60-year-old billionaire John Sall still enjoys cranking out code as the chief architect of JMP ('John's Macintosh Project'), the less-profitable-but-more-fun software from SAS that's used primarily by research scientists, engineers, and Six Sigma manufacturing types. 'It's always been my job to be a statistical software developer,' explains SAS co-founder Sall. So if you didn't have to work — and had more money than George Lucas and Steven Spielberg — would you be like Sall and continue to program? And if so, what type of projects would you work on?" -

SAS CEO Blasts Old-School Schooling
theodp writes "What does SAS CEO Dr. Jim Goodnight have in common with 47% of high school dropouts? A belief that school is boring. Marking the 50th anniversary of Sputnik with a call for renewed emphasis on science and technology in America's schools, Goodnight finds today's kids ill-served by old-school schooling: 'Today's generation of kids is the most technology savvy group that this country has ever produced. They are born with an iPod in one hand and a cell phone in another. They're text messaging, e-mailing, instant messaging. They're on MySpace, YouTube & Google. They've got Nintendo Wiis, Game Boys, PlayStations. Their world is one of total interactivity. They're in constant communication with each other, but when they go to school, they are told to leave those 'toys' at home. They're not to be used in school. Instead, the system continues teaching as if these kids belong to the last century, by standing in front of a blackboard.'" -
Managing for Creativity
theodp writes "After seeing some of the ideas management comes up with as a result of reading the Harvard Business Review, you may be tempted to hide their copies. But make sure they see this month's Managing for Creativity by Dr. Jim Goodnight, the still code-cranking CEO of SAS, the world's largest privately held software company." From the article: "Many academics and businesses have made inroads into this field. Management guru Peter Drucker identified the role of knowledge workers and, long before the dot-com era, warned of the perils of trying to "bribe" them with stock options and other crude financial incentives. This view is supported by the research of Harvard Business School's Teresa Amabile and Yale University's Robert Sternberg, which shows that creative people are motivated from within and respond much better to intrinsic rewards than to extrinsic ones." -

SAS Institute Announces Linux Port Of SAS Software
stoney27 wrote to tell us about another big -- no, make that huge name porting their product to Linux. This time, it's SAS, porting their SAS data-warehousing and management software to Linux. In a world filled with FUD and innuendo, it's refreshing to hear SAS research vice president Bob Moran explain the move by saying "[m]any IT managers are attracted to the reliability and ease-of-use of Linux." Given their market, it's almost predictable that the first release is for Red Hat specifically, but this release says they intend to support all major distros. -
