No, that's the point; the previous algorithm was O(1) [a simple queue] but that led to doing a huge amount of extra work. By using a smarter queue that "cost" an extra O(log(n)), we could skip work that didn't need doing

To be clear, sometimes a terabyte of RAM is the right solution. But it's pretty common to find someone needing that simply needs a better algorithm. [or, recently, a mathematical identity that meant the task could be done streamed from

I don't cross paths with a lot of C or C++ where profiling is a concern. I use gprof for that, but I haven't needed it in a few years. None of the folks I work with reach for C or C++ as a weapon in their quiver. I do cross paths

The stuff I've used in recent months: - For Java, personally I like the netbeans profiler - Octave's built in profiler gets the job done: https://octave.org/doc/v6.2.0/Profiling.html - I use JetBra

This place has been an astonishingly good fit for me, yeah. I was laid off from my last job, and a friend passed along my resume at an opportune moment. That was twelve years ago, and I'm still here. My group has a perpetually open pos

Finance guys tend to be able to afford to have the right people to be sure of that on hand; they also are specifically in the business of cost-benefit analysis. I have no insight or information this; but sometimes you can throw money at a p

The mathematician that designed the model I referred to at the end ended up passing it on to me. I've now built something of an empire of people and projects using it, "just" by making better tools to manage its inputs, outpu

Oh, and not to tar with toooo broad a brush: One guy contacted me the other day wanting a terabyte of memory. He'd actually done all his homework and had a weirdly interesting use case. I'm actually pretty excited to explore get

I, too, am a software engineer dealing with researcher code on a daily basis, and I'm also the person that oversees most of our research compute hardware [sysadmin in a past life]. Some of my other favorite gems: * "I need a t

The inconsistent and self incompatible licensing of tidyverse has stopped my company releasing source code to R things a couple of times. I see they're working on getting everything to MIT, but at least for now... (I say this as both o

The first time you're turning right and the wheels come off the ground, it's truly terrifying. Because the first time it happens you literally have no coping mechanism and simply careen forward in a straight line, because no intui

I have a sidecar attached to my Honda shadow. It's a weirdly fascinating thing ; riding a sidecar is as different from riding a bike, as riding a bike is from driving a car. The dynamics are all different, handling is absurd, etc. A pr

Where I work we moved to a fancy backup solution a few years ago. Which one doesn't matter but suffice to say the name implies the focus isn't on metal Not a single one of our metal machines ever successfully backed up with it. Te

My new cellphone literally has a Hasselblad camera on it. I get all the things that make better cameras better, but I already have stupidly high end living in my pocket. It's not like that company would put their brand on anything crap

I was looking for something like this the other day. I ended up just implementing functions directly in sql like plot_bar(category, value), plot_points(xval, yval), which open a popup with the chart.

So, in conclusion it's a hack... but, it's also incredibly robust. It doesn't hurt, and we acknowledge there are cases where it could help. It's idiomatic enough that literally everyone who's done a nontrivial amoun

I implemented a DB visualisation tool like this for sqlite3, also using graphviz. It's called, unimaginatively, sqlite3todot [1] The couple tricks it has that I really like are a) it shows the table itself [which isn't uncommon],
