Do you have some reason to believe that Google seriously hosed the Java implementation on Android or these guys have massively increased the efficiency of the Python implementation? Otherwise, it seems the answer would have to be yes.. the

Post-it notes are more powerful tool than most people realize because they: - Rearrange easily (no copying) - Support text and diagrams - Are concurrently editable (as a group) - Convert virtually useless walls into huge work surfaces The i

They've offered more and more powerful instances as hardware has improved, and they offer spot pricing allowing the market to set the price for spare cycles. Offering smaller instances is a good thing for a variety of reasons from simple co

Perhaps you're right.. Have they continued to eliminate features they didn't like in releases since 2002? As far as I could tell, VB.NET wasn't an upgrade to VB6, it was a product introduced to smooth the transition to C#... like Lotus 1-2-

You're right: it's primitives sucked. However, VB let people do a huge amount of work without code: Think the GUI designer, VBX/OCX controls, and OLE embedding. That's the power i was talking about, not a way to implement advanced algorit

Are useful and powerful the opposite of sucky to most people? Not to me. Consider a parallel example: Visual Basic (pre-.NET, think ~3.0) opened up programming for GUIs to a much much broader audience (because Hypercard was made for a far l

Don't try to teach the machine things you don't know yourself. Study the rules and actors in the systems you're studying, and come up with theories to test against the data. You'll need to do this work anyway, so it's at least a good way to

It can, but it's usually an impossibly huge search for a way to turn garbage into gold.

One of the key lessons in finance is that you can't make money doing what everyone else is doing. This is only true in the long run, and not true for individuals. As a simple example, consider the practice of selling far OTM options.

I can think of lots of ways to eat 80% fresh produce on $1/day, at least by the post's standards.. a plot of dirt, a short skirt, etc.

I've read this over and over again, and I can't tell if you're agreeing or disagreeing with me! Defocus spreads a point of light over more than one point in the image... as does the "antialiasing filter."

Not coincidentally, the color camera's bayer filter and the pentile matrix use an awfully similar RGBG matrix arrangement. Each "pixel" you get RAW off the camera is only R, G, or B. The "full" resolution is synthesized in "demosaicing."

You may be interested to know that nearly all digital cameras advertised resolution is the total number of what you call "subpixels."

I just meant to be offering constructive feedback. The tutorial was useful for me. It's certainly way better than the tutorial I had before you wrote it! It's pretty impressive for an hour of work.

by ggruschow 16y ago
Nice work. Assuming you're trying to advocate Clojure, I'd recommend changing your tutorial to make things look easy (as opposed to highlighting gotchas). I recommend doing math examples first. Show how it makes a good calculator, but avoid

It's only a zero sum game if you don't consider all the fees and taxes. Doing so would be total folly. The fees and taxes make up a huge portion of the profits and losses on these strategies.

The way HFTs use leverage is opaque to most margin systems. Intraday margins are allowed to go way outside of overnight margins, and only positions are margined, not orders. That said, there's also traditional leverage used in many cases be

This is just a stop-gap measure to get some income before you implement context-sensitive ads, right? Most advertisers won't get any value from most searches.

It's not just backup because you can share directories across dropbox accounts, and dropbox maintains that central repo on as many machines as you want.

There's also the other problem: saturation. Everyone who I know who wants to use an iphone already has one. A number will upgrade when the next one comes out. I have an ipod touch, but don't want to have to carry that much size/weight to
