Action against underspending

Are you also notoriously leading your department into problems by underspending on your budget? I am proposing a 3-step solution:

• Send me e-mails with the expected amount of underspending
• I will sum up the stated amounts
• At the end of the fiscal year everyone transfers the money into an escrow acount to finance a new space program

Update: So far I have received estimates amounting to £60,000.

Hornetseye-0.20 released

I have released version 0.20 of the Ruby extension HornetsEye. The new release comes with an implementation of the Dual-Tree Hypercomplex Wavelet Transform. The DHWT is useful for filtering 2-D signals.
