Take it as a challenge. Programmers of 70s & 80s did amazing things with limited memory and CPU. We're largely spoiled nowadays and often don't have to pay attention to memory usage or CPU usage. Being forced to pay attention to these details will make you a better programmer in the end.

Available now for OS X 10.4 and 10.5, and through Apple's Software Update service, this update patches a flaw in the Java Virtual Machine that could potentially allow a malicious Java applet to execute arbitrary code on the machine. Apple had previously advised users to turn off Java temporarily in their Web browsers."
destinyland writes "Sun Microsystems has helped fund a 198-page nanotechnology roadmap — but how close are we to real nanotechnology? A science writer asked four nano pioneers, including K. Eric Dexler ('progress is accelerating') and Ralph Merkle ('the exponential trends continue to be exponential') Though we don't have Star Trek replicators yet, the article lists some surprising recent nano developments (artificial tissue, nanoparticle sheets, ultrathin diamond nanorods). And the roadmap's scientists are envisioning targeted cancer therapies, super-efficient solar cells, high-density computer memory chips and even responsive 'smart' materials."
