This post describes my experience using a Raspberry Pi as a wireless VPN gateway. In particular, how to solve the terrible performance I had initially.
I have been doing more work on flash memories and decided to write up the notes I have been taking.
This article is about the technology behind flash memory: how data is stored, the architecture of flash memories and (briefly) how data is read, written and erased. (This may turn into a series with more detail on various aspects of flash technology.)
Solid-state drives (SSDs) based on flash memory are increasingly replacing hard disk drives (HDDs) for mass storage in many applications. A quick check of an online retailer showed that about half the laptops and desktop computers used SSDs.
One of my recent projects was an article on the display technologies used in mobile phones, laptops, TVs, etc. As is often the case, I learnt a lot from researching the piece. Which was useful as I was thinking it is about time to buy a new TV.
