Looks like a very nice feature - but would be great if they provided some actual benchmarks showing when vectorization is faster than not. For example, if you're bound by memory bandwidth, no amount of extra compute is going to help yo

I'm reminded of the old joke, "python is executable pseudocode, while perl is executable line noise." But seriously, I've got some battle scars from the perl days, and hope not to revisit them. Honestly, there's ver

Some more tips from someone who does this every day. 1) Be careful with CSV files and UNIX tools - most big CSV files with text fields have some subset of fields that are text quoted and character-escaped. This means that you might have &qu

I have golfed since I was a kid (grew up in the mid-Atlantic), and have been a serious golfer for the last 7 years or so - having lived both in Boston and the bay area during that time. I very rarely bet any money on my round, nor do the pe

Why is that number ridiculous? At ~1% of the workforce, this means that the average American laborer needs 2.5 days/year of lawyer time to keep them fully occupied, which honestly doesn't feel like such a stretch to me, given that

A few points that will likely get lost in the noise here: 1. It is weird to take the top graduate schools and ask about what they teach to undergrads. I'd rather see this done with the best national universities list - http:/&#x2

I hear Java people say "I love scala" a lot. I do not hear people coming from other environments saying this.

It seems that a lot of people are missing the point. Leveraged Sellout was famously satirical of the financial markets in the heady pre-crisis days of '06-'08. Even published a book: http://www.amazon.com/Damn-Feel

This type of crowdsourcing meets ML is a really nice example of where we can leverage humans and machines to the best of their current abilities. It would be great if the feedback from the human workers could get reintegrated into the trans

I like that they're still referred to as a "startup" even though they exited for $170m nearly 5 years ago.

If you want to take a look at scaling page rank on commodity clusters with R, you should take a look at the newly released SparkR ( http://amplab-extras.github.io/SparkR-pkg/ ) and possibly just call into GraphX ( https:

I don't follow the connection between your comments. XML Support as selling Point + Multiparadigm == !mainstream? I agree that scala has its quirks (IMO, the type system is way too complicated), but to have dismissed it based on two ap

I helped write the AMPCamp exercises (and parts of Spark) - the exercises were done in the context of a two-day long seminar held at Berkeley where the days were mostly filled with talks/training about the stack. The actual exercises w

To play devil's advocate - isn't the reason you're sorting so that you can find information more easily? Aren't you manually performing search yourself? While not perfect, I think searching for "from:sender" is

Most of the HN clones you see (that share the style of HN) are built based on this Arc example. Note certain features of HN (like the rules used for scoring posts) are not in this source code.

Right, but in this example it's not telling me what the "grep" is doing. Admittedly xargs is a weird case where the arguments to the program are invoked as a program, but I'd say it shows pretty frequently in these type

The first reason I ever set up a VPN connection was to play MCM with randos across the internet. The first version only supported multiplayer over LAN, so you had to configure a PPTP client and find a "server" to join that had oth

Where does that 6x speedup come from? Is it a different algorithm? How is the 1d process different from the 2d? It might be that the 2d lib is just better optimized.

Would love to see how this works vs. just finding the max correlation of the 1d sampled stream vs the base data. If that's no good - try fft on the 1d sample and rescale.

Perhaps the point of the article was to stir conversation, but I'd prefer it if they'd actually propose some ideas, rather than saying that it's different now. I'm not a huge fan of Agile, but I do think it encourages so

The point is that currently the Scala compiler provides one target - the JVM. Support for .NET was officially dropped last year, and nobody seems to care. Scala and the JVM are very tightly coupled - targeting LLVM or something should be
