Ah, I should have been more precise and said "assign" instead of "cast". R assigns a 64-bit int to a double, and therefore loses precision in certain cases.

Workarounds like those you mention are what I wound up using. I did more work outside R and less inside R. These days, for many projects I no do almost nothing in R.

The point is that when scientists write software they store big numbers in floats because no sane person needs more precision than that. The idea of huge, exact numbers is foreign to physicists and chemists and statisticians. Especially statisticians.

Only computer programmers and cryptographers need huge, exact integers.

I think you're right, and I see the same kind of thinking when I ask about 64-bit integers in R. The people who use R are statisticians who can't imagine why a double isn't close enough. The people who complain about it are the computer programmers who are trying to use 64-bit exact fields to merge two datasets etc.

FWIW, GNU R, the freetard knockoff of S, also can't do anything with 64-bit numbers. It stores them in a double, which gives you 52 bits of exact integers and beyond that it's approximate. This can really bite you in the ass if you aren't aware of it ... and it's not documented anywhere except in code. It can be especially bad if you try to read a BIGINT (64-bit integer) value via RODBC, which silently truncates the value to 52 bits.

Well, you're wrong. Current wifi chips which come loaded with "world" firmware will never broadcast on 5GHz channels unless they first see beacons from an AP on that channel. These channels are marked for passive scanning only. When a device sees a beacon on that channel then it assumes that local regulations allow wifi on that channel, and the chip will enable it. The chips used in access points, by contrast, generally are shipped with locale-specific firmware, or at least locale-specific black box operating systems.

This is why the wifi card out of your laptop can't really be used as a decent access point. You can't get them to ever broadcast beacons on the 5GHz band.

This is not what war is like, this is what cowardice looks like. If armored infantry are so afraid of 8 photographers walking down the middle of the street that they have to hide inside their armored vehicles waiting for a helicopter to investigate, then those infantrymen are chickenshits. Plain and simple. I'm sure you'll say that the grunts just want to make sure they don't get dead, but the fact is that they're armed to the teeth and in a city crawling primarily with unarmed civilians. They are going to have to be men and not hide behind FLIR gun pods.

"Hearts and minds" and all that.
