Agreed (at least to the first part). The same argument has been made about the new web font technologies. http://hackademix.net/2010/03/24/why-noscript-blocks-web-fon... "It really worries me that the FreeType font library is now being m

"malloc never says no" malloc says no if you set a ulimit in your shell. I do this on the desktop to stop myself from shooting myself in the foot. (Recent kernels also let you turn off the overcommitting behavior.)

KNN "no learning involved" : one probaby wants to cross-validate K at the least, if not learn the metric. Some methods say online learning isn't applicable. As pointed out elsewhere, objectives for K-means and mixture models could be fitte

I tried not to be that guy and already gave some alternatives for regression. “Polynomial regression” implies to me that the basis functions are polynomials. I‘ll assume you meant “good basis for a simple fit, maybe by least squares”. Mor

Terrible generalization of polynomials is useful for demonstrating overfitting (I've done it myself in tutorials). However, responsible tutorials should mention that the other obvious lesson is that the polynomials (1, x, x², x³, etc) are a

As an academic, I would advise lay science enthusiasts to steer clear of anything classified as "general physics" (or "general mathematics") in the arXiv. There's far too much of it, mostly junk, and you'd be better spending your time elsew

The persistence and the dedication needed in skateboarding—that's what we need to be teaching. No one says to a toddler, 'You have ten weeks to walk, and if you can't, you get an F and you're not allowed to try to walk anymore.' It's absur

I don't know, but it would be easy to do. Give the user a long random string that they need to temporarily add to their HN profile about box.

Sort of, on Linux. See my comments elsewhere on this page for an inotify "replacement" of atchange, and notes on why it won't do quite the same thing as the perl script.

by imurray 16y ago
Thanks. Below is the version I'm trying. It allows multiple-argument commands, doesn't stomp on atchange if inotifywait isn't installed and I wanted it to fire when touching files as well as modifying them. if which inotifywait > /d

by imurray 16y ago
Thanks! When I first used atchange (detailed in another comment) I saw mention of things like inotify, but didn't have the kernel support on the system I was using. Fast-forwarding to now, having just installed inotify-tools (Debian/Ubunt

How many times did I want to watch a directory waiting for a file to appear in it? For this sort of thing I use a simple perl script called atchange. I could do: atchange . ls And I'd see list output whenever a new file appeared i

Also Firefox doesn't put DNS through a socks proxy by default, which has some security implications and doesn't allow you to reach internal-only names. In about:config set: network.proxy.socks_remote_dns to True.

I suppose I use screen heavily — I run it a lot, but usually forget that I am. When I connect to remote hosts, I use a script (which among various other things) runs: ssh -t remote.host.net screen -D -R -S "$(hostname)_$PPID" Then if

That's true, but as you say UK students aren't necessarily that tied down. I moved (in the UK) from a physics undergrad to research in machine learning and statistics. This sort of move is common.

by imurray 16y ago
I recommend the anonymous comment starting: It's unfair to characterize a UK PhD as "a good US Master's thesis"... http://matt-welsh.blogspot.com/2010/09/so-you-want-to-go-to-... — it's pretty fair and accurate.

There can certainly be some dark times. Sometimes when reading PhD comics I didn't know whether to laugh or cry! Do I regret doing a PhD? Not for a moment: on balance my PhD and postdoc years were fantastic . Although part of my happyness
