The reason why I seperate weather data collection in Arduino and database and Internet programming in Raspberry Pi is I like modulized design.Both system are independent to each other.It make life a lot simple.
The use of color here really highlights certain portions of the packet header. For example, the source and destination addresses and ports really jump out. But there are some other, more subtle color patterns that I worked in here. For example, if you look closely you’ll see that I matched the color of the ACK bit with the blue in the ACK number field. Similarly the colors of the SYN bit and the sequence number match, as do the URG bit and urgent pointer field.
For Type I patients, who must inject insulin several times a day, the new system will be less useful. The problem is that it takes time for changes in the blood sugar levels to be reflected in the saliva. And that means the concentration of glucose in the saliva always lags that in the blood by around 30 minutes or so. That’s long enough to cause serious problems if, for example, sugar levels in the blood are dropping precipitously.
Nevertheless, carbon nanotube-based sensors could be significantly cheaper and more robust than the enzyme-based ones that are commonly available today. And that in itself is an important factor for healthcare systems already overburdened by the high cost of treating this disease.
