Carrie getting some much deserved attention. "Ms. Grimes is an Internet-age statistician, one of many who are changing the image of the profession as a place for dronish number nerds. They are finding themselves increasingly in demand — and even cool. “I keep saying that the sexy job in the next 10 years will be statisticians,” said Hal Varian, chief economist at Google. “And I’m not kidding.”" - Bret Taylor from Bookmarklet

Great article, but it left out that statisticians need some CS muscle to effectively operate on large scale data. It's the combination that make Carrie -- and others like her -- 'Internet-age' statisticians. - Michael E. Driscoll

In this day and age, caching effects outweigh most algorithmic gains (for most data sets that you're likely to encounter). The cost of a cache miss can be disastrous -- going to main memory is roughly 200 times slower than hitting in your L1 cache. This is why...

1. Tree-oriented data structures are usually a bad idea. Every branch means you're chasing a pointer to some completely unrelated area of the memory, likely a cache miss. - Tudor Bosman

2. High-performance server code is hard to write in Java (as opposed to C/C++). You can't embed objects in each other; every object reference means following a pointer, likely a cache miss. Also, objects are huge -- they contain a vtable and a lock and all sorts of other crap that you often don't need. - Tudor Bosman

3. You get surprising behavior with C++ STL data structures. It's often faster (for small-sized data sets accessed infrequently) to store them in a vector and do linear search than to store them in a std::map (which is a tree) and do binary search. - Tudor Bosman

Every programmer should read this. http://people.redhat.com/drepper... - Tudor Bosman

This, by the way, is why I don't like Java. Write most of your code in a high-level language (Python, PHP, Javascript, Lisp, whatever floats your boat), which is easy to write, read, debug, and deploy, and the performance-critical parts in C++. Java is trying to sit in the middle, but doesn't do either "ease of use" or "high-performance" particularly well. - Tudor Bosman

Techniques originally designed to minimize disk seeks now make sense for data held in RAM. For example, btrees can be faster than red-black trees on modern machines: http://idlebox.net/2007... - Ben Darnell

Coincidentally, I found this just now, linked from Reddit. http://msinilo.pl/blog/?p=614 - Tudor Bosman

I'd critique this assertion on a few grounds. One, while you do not have control over object embedding, there is nothing preventing it, and indeed, there are tons of papers on "object inlining" compilers, in much the same way that escape analysis can allow automatic stack allocation. It is true that current JVMs don't do this, but it is not prohibited. Secondly, compacting garbage... more... - Ray Cromwell

I feel the same way about Java being in the middle. If you only pick one language that might be the thing to use. But if you're using two, a combination like C++ and Python seems better than C++ and Java, or Java and Python. It may be true that JVMs *could* inline objects, but they don't, and that's what matters to me as a programmer (not a compiler writer). However I think there could... more... - Amit Patel

OT, but "When it comes to operating-system-specific details and solutions, the text exclusively describes Linux. At no time will it contain any information about other OSes. The author has no interest in discussing the implications for other OSes. If the reader thinks s/he has to use a different OS they have to go to their vendors and demand they write documents similar to this one." - Andrew C (✓)

Some would that a high level language that requires programmers to specify object allocation and layout is basically not a high level language. HLLs tend to defer such design decisions until later, relying on the compiler, because early optimization could inhibit later reuse (e.g. declaring a method 'final' in Java for 'performance') The dismissal of the JVM's current optimizations... more... - Ray Cromwell

Related, it has already been implemented in HotSpot (http://citeseerx.ist.psu.edu/viewdoc...), 9% average to 51% speedup. Also, JDK6u14 has experimental escape analysis, but not full stack allocation yet, however, IIRC the IBM J9 VM has had automatic stack-allocation for non-escaping objects since early 2000s. - Ray Cromwell

back in 99-03 we had rather opposite problem -- we had to reduce capacity/bandwidth (on now obsolete pentiums :) yeah, we had also to keep it running 99.999% reliable, hotswappable, on _minimal_ hardware support, and what not else. The Decision we made to make it _that_ capable was to drop C++ & C mix and write it plain C ;) Moral of story -- don't over-engineer :D - A. T.

I don't know what datasets you use, but it only takes a few thousand or so nodes to make an O(log n) tree algorithm faster than an O(n) list algorithm, even when a node access it 200 times slower than a list access. - Gabe

Are you suggesting that a O(n) algorithm is better than O(log n) because the O(log n) has a constant factor of 200 (or even 1000)? - siva

I am suggesting that a program that uses an O(n) algorithm might be faster than a program that uses a O(log n) algorithm under the circumstances. I'm not comparing the algorithms, but their implementations on real hardware. - Tudor Bosman

and with real-world data sets. Depending on your application (say... videogames), they might in fact be quite small. - Andrew C (✓)

"Many circumstances can trigger anger, but one that is commonplace in the male adolescent culture of cruelty is the feeling of inferiority or being devoid of social status. There is little scientific evidence to support the admittedly popular idea that boys with high testosterone levels are aggressive and yet have higher social status..."

cont'd. "Our clinical experience also refutes the notion of such a biological imperative. It is not the virile class leader who is usually the bully or the one getting into the fights after school. It is the boy who is further down the social ladder, one who feels rejected or ashamed, who expresses his hurt through aggressive action. Clinical evidence tells us that boys who have the genetic defect Kleinfelter's syndrome tend to be aggressive. Kleinfelter's is a clinical condition caused by an extra female chromosome (XXY), and affected boys have small genitalia and a testosterone deficiency. Clinicians who work with these boys report that they tend to be self-conscious because, especially for those on the cusp of puberty who must shower together after gym class, penis size is a visible measure of manhood. These boys tend to get into trouble fighting, perhaps to protect themselves against the pain of this shame and perhaps in part to validate their manliness.

"Toyota North America hired several employees directly from the National Highway Traffic Safety Administration (NHTSA). These former government employees helped to end NHTSA probes into unintended acceleration occurring in some of the same vehicles that are now being massively recalled and which are apparently responsible for causing deaths. The probes were ended in 2002-03, and the employees consistently lobbied against any expanded inquiry into these issues over the past decade." - Andrew C (✓) from Bookmarklet

"The irony is that Toyota's regulatory lobbying effort was in pursuit of short-term gains that ended up causing long-term damage to their reputation. As with banking, special treatment given to firms at their own request has been damaging -- even fatal, to their own existence. In Toyota's case, it has led to the tarnishing of their once impeccable reputation, and regrettably to the deaths of 19 of their customers." - Andrew C (✓)
