Looking for contract jobs that take advantage of my RS232, .Net Serialport expertise. Collaborating on projects that have serial port requirements is also acceptable.

Willing to travel on a limited basis.

Please feel free to contact me via email.

comment Why do higher level languages have neither xor nor nand short-circuit operators?
Short-circuits make sense in this context, if true andalso(orelse) thistrue. XOR doesn't.

comment What does the English word “for” exactly mean in “for” loops?
The OP was looking at how the code statement could be interpreted. Most of the answers were you can't. I provided an alternative, a way it could be(loosely).

comment Which is Preferable: FirstName LastName or Forename Surname etc
40. People have names. That one confused me, but I am sure there is an example. I was born in the US and have three names. Unfortunately for me I go by my middle name. Thanks a lot mom and dad.

comment Does data size in TCP/UDP make a difference on transmission time
Typically there are three scenarios. One is real-time data (e.g. voice over IP), data transfer (e.g. FTP), and poll/response (e.g. HTTP). In the first two case the size of the packet v. frame rate is of importance. For real-time the size of the packet is smaller but sent at a fairly fixed rate. In data transfer you are more interested in sending as much data as possible. In the case of http data neither much matter.

comment Does data size in TCP/UDP make a difference on transmission time
The downvote wasn't mine. UDP as defined in RFC 768 assumes that IP is the underlying protocol. The OSI model was intended to be layered such that any layer could be replaced.

comment Does data size in TCP/UDP make a difference on transmission time
When I started networking (mid 70's) error rates were a huge consideration. Over time it became less of a consideration in most cases. Modern wired / optical networks are almost error free, and wireless networks are getting there.

The basic statement made by the OP is correct. What protocol, and size of data packets, chosen definitely depends on the application.

I agree that the time the data is on the wire is longer for larger packets. It is also true that UDP has smaller overhead. What other network layer protocol does UDP run on?

comment Does data size in TCP/UDP make a difference on transmission time
If you have ever noticed the specifications for an Ethernet switch it is given as BPS (bits/sec) and FPS (frames/sec). These two measurements are mutually exclusive. To attain the BPS spec. the frames have to be max size, and for FPS the frames have to be min size. As long as the data you are transmitting, with overhead, fits into one physical frame, bigger is more efficient. Bear in mind that along the path the data may have to fit in different size physical frames. Basically the statement made to you is correct for both UDP and TCP.

How about BONSOP, which is still used today ;)

comment Where can I find a punched card simulator?
FYI - Hanging chads weren't an issue when using keypunch machines. They(chads) were a result of the use of 'scored' cards that could be 'punched' without a machine.
