Also keep in mind that if you have an SLOG (ZIL on a separate device), and then 
lose this SLOG (disk crash etc), you will probably lose the pool. So if you 
want/need SLOG, you probably want two of them in a mirror…

I all pedagogikk er det essensielt at pensum presenteres intelligibelt. Det er 
et elementært imperativ for alle pedagoger å unngå eksessiv anvendelse av 
idiomer med xenotyp etymologi. I de fleste tilfeller eksisterer adekvate og 
relevante synonymer på norsk.
