The point he's missing is that you don't have to develop software on the same computer you test it on. The best solution is to have a separate test computer that's appropriately slow. In fact, most people probably already have an old one lying around that they could use. And regardless of speed, it's good to test your software on a variety of systems.

I certainly do test on many different systems, but not all of them.

This doesn't take the place of real-world testing. It takes the place of setting up a network and putting a modem between my client and server then attaching a tape drive to my server to see what happens.

So far, it's been quite useful, but I've got a ways to go.

I don't believe I communicated clearly enough in the creation of this project.

This is not ``Yay, I don't ever have to worry about any other computer because I can simulate anything.''

This is me sitting next to my QA guy (who really understands what I did better than I do so far) and having him say, ``Why don't you just make it fast for the first ten minutes, then slow down socket operations briefly, then switch a pattern of speedup and slowdown on disk reads?''

I want to do more fault injection stuff. I'm being asked to do stuff like manipulate the data (sometimes), or lie about the results of certain operations.

Wouldn't all this depend on your target customers? If your target customer is big business that have fast computers you are okay.

If your customers are average joes, then yes I would say you should have a test environment in place that closely represents those customers.

Even after all that the question I have is which set of customers brings in the most money for you? Lets say you have a mix of big business that run fast machines, and average joes that run slow machines. If 90% of your money comes from big business, why bother trying to make software for the slow machines? Just slap on a system requirement and it should cover them, so-to-speak.

Another site that rips off the HN comments verbatim?

Hi everybody, I'm doctor copyright-infringement!

That's Disqus (YC S07). Its "reactions" piece pulls in comments from sites like HN, Reddit, and Digg into the comments widget it puts on a given blog post.

Great work, but I think a library to do the opposite would be more useful.

... to make your computer go faster than it really is?

That WOULD be pretty useful.

Or are you merely talking about libraries that do optimization for you?

Bleh. It looks pretty useless without threading.

EDIT: By threading, I mean conversation threading; this isn't a misplaced comment about the performance of La Brea.

I concur. I've never really found it useful.

I see. Does HN say somewhere that "anything you submit can be used for commercial purposes by YC startups"?

Interesting point, I googled for 'who owns copyright blog comments' and found this (Google cache, the site itself is down):

http://webcache.googleusercontent.com/search?q=cache:6GfoIFr...

I'd like to hear if anyone else agrees or disagrees with this article (it seems to be a bit of a grey area).
