>I don't understand your response. Are you saying the OCaml community primarily consists of undergraduates? What I am saying is that a sizable portion of academia uses a variant of ML. Maybe it hasn't caught on in industry, but

But there is a strong community behind OCaml. A lot of undergraduate programs use a dialect of ML for their core classes. While most OCaml implementations have poor standard libraries, Jane Street Capital has released several open source li

Yeah, when the lists are sorted, you need the intuition that you can merge two sorted lists in less than n * log n time. Like you say, the best you can do for merging several sorted lists is (sum of lengths) * log(# of lists).

I'm curious, what kind of a solution are you looking for with that problem? The trivial solution of concatenating the lists and then using a library sort (or cobbling together quicksort) is about as good as it gets for small lists. For

by sgeisenh 12y ago
Yeah, random pivot quicksort is n log n expected case. Its pretty easy to show that it is realistically impossible to exceed n log n for large data sets. The constants are quite high, though, due to the need to generate a random number for

Computer Science trains students in thought processes. Since quite a few companies use a limited number of tools and frameworks, most CS graduates can jump in and be productive pretty quickly, given the proper on-site training. Problems ari

I am partial to services that let me use OBS. Not sure why several streaming services are rolling their own desktop clients.

I have a late 2013 15 inch MBP that regularly reaches 100 degrees C when running Adobe Flash. The only other time the machine has exceeded 70 is when I tried running Steam games at 2880x1800. The hardware simply shouldn't get that hot,

At least you know the adapter is working if it crashes your computer. I am lucky to get the adapter to work properly and when it does, plugging in my Shimian crashes my MBP.

Does anyone else find Clojure's syntax a bit obtuse? I feel like basic recursive definitions are much clearer in Haskell and ML. To sum over a list using an accumulator shouldn't take more than two or three trivial lines of code.

Agreed. Lectures enforce pacing and accountability better than I ever could on my own.

Check out /r/unixporn. There are some excellent setups in there. I think the lack of a standout tiling window manager might be the result of the quantity of excellent WMs in existence. Regardless, if you've never had an exper

What is excellent about chamber music, in particular, is that no individual makes the musical decisions. Each musician is talented enough to be able to react and expound upon the decisions of each of the other players. Honestly, chamber mus

Often times, in the standard repertoire, the conductor doesn't necessarily do anything in the performance. It is in the preparation, when the conductor disseminates their interpretation to the ensemble, where their artistic vision is f

This is an interesting idea, but I suspect that most consumers are inclined to pick and choose services. Maybe Amazon can fill a niche with this type of offering. Beyond viability, I find the implications of this post terrifying. The line b

The arguments of most of these types of posts can be hand-waved with "use the right tool for the job." But honestly, plumbing and electrical infrastructure is a terrible metaphor for a development framework. There is no situation

Inconsistent sleep patterns can also cause circadian rhythm disorders. I struggle with delayed sleep phase syndrome as a result of years of poor sleep hygiene. I use what is called chronotherapy ( http://en.wikipedia.org/wiki

I think, within a certain threshold, it is definitely more financially responsible to bootstrap. Though, I agree with your point about Twitter, etc: if you're a seasoned developer/entrepreneur with a large scale idea that requires

I am talking about frontier A* where you discard all nodes that have already been visited. This requires the heuristic to be consistent. As opposed to the breadth-first heuristic search which revisits nodes.

If we operate under the assumption that each intermediate path found is shortest for its respective endpoint (which is the fundamental insight for Dijkstra's), we could potentially throw away the solution because it travels through the

I'll do my best to provide an example. It is hard to come up with a general idea, but I can demonstrate using a graph: http://i.imgur.com/AwpTeRt.png The numbers in the nodes represent heuristic values at each node and

by sgeisenh 13y ago
The discussion of heuristics includes only information about admissibility and not consistency. An admissible but inconsistent heuristic can also cause A* to miss the correct solution.

While breadth-first search and Dijkstra's have a lot in common, Dijkstra's is a priority first search which is inherently sequential, whereas there is some parallelism to be had in BFS since you can check the neighbors of your fro

Wait, do the results from each round make a difference in subsequent rounds? I didn't take the time to implement a solution to problem C because I felt like it would take too long.

Authenticator tokens are pretty robust systems. I'd like to see more services start to make use of them.

With the exception of hybrid shipping, I am consistently impressed by Amazon's ability to ship using the most appropriate service. Perhaps it is due to my location in an urban area; when I use Amazon 2-day, it arrives in either 1 or 2
