He sat back at his desk, the blue light of the monitor reflecting in his tired eyes. He realized the "free" version he was looking for was a ghost. In the engineering world, "free" often meant "unverified," and in a lab with hazardous fumes, "unverified" was a fireable offense. The midnight Pivot

Elias knew the problem. He was guessing loss coefficients. He needed the . But the firm’s budget was tighter than a rusted shut damper; they wouldn't spring for the $150 software license.
