What is the fastest way to add an attribute to the root element of a massive XML file? These files are too large to be read into memory and I'd like to avoid as much of an I/O penalty as possible.

Aren't you going to have to rewrite the entire file anyway if you're inserting text at or near the beginning? A SAX parser should be adaptable to buffer input (via an InputStream) if you don't want it all in memory at once .

Is there any good way to design a web page for massive data entry? Datagrids seem to be the best way to handle this type of data entry and I think a client application like Access or SQLite+Frontend would be better suited for this than the web.

All of this can be done with JavaScript.
So no clicking submit buttons and no waiting for page reloads .
The important part would be to make everything keyboard-accessible, and to reduce as much as possible the wait time between records .

I am interested in any experience using JS charting packages handling massive amounts of data (for example tens of thousands of data points).

It can do things like this.
If we are talking about large data for gMap there is a Cluster Marker .
I have used google maps to display polylines; I've been facing huge performance issues when the polylines had more than a thousand points .

Simple question hopefully.
We have a style sheet that is over 3000 lines long and there is a noticeable lag when the page is rendering as a result.
Here's the question: Is it better to have one massive style sheet that covers everything, or lots of little...

What you can do is use a locking hint to reduce the locking overhead and potential contention .
Sorry it is not possible to add a WHERE clause to TRUNCATE
You will have to use a DELETE
You can't use a WHERE with a truncate: it's all or nothing .

My integers in Ruby (MRI) refuse to overflow. I've noticed the class change from fixnum to bignum but I'm wondering how this is modeled and what sort of process ruby uses to perform arithmetic on these massive integers. I've seen this behaviour in SCHEME...

Basically, it boils down to long-addition/multiplication/division/subtraction.
You can take a look at the source code (in C) in the erl_interface module .

We're using rsnapshot for backups. It keeps lots of snapshots of the backuped up file, but it does delete old ones. This is good. However it's taking about 7 hours to do a rm -rf on a massive directory tree. The filesystem is XFS. I'm not sure how many...

This is why block based snapshots are so good:).
