comment Will ReadyBoost help at 8 GB RAM development machine?
SATA 1,2, 3 run speeds to disk of up to 6 G bits / sec. Its possible that drive latencies will reduce that to a series of bursts, and its also possible that an SSD will have less bursts than a mechanical HDD. On raw speed tems though, I can't see how USB would ever be faster.

comment Does it make sense that the lower a router is to the floor, the worse my reception?
Reflections CAN help for MIMO receivers, only because of the spatial separation. Where one antenna sees a null, there is a reasonable chance that another antenna won't see a null simply due to the spatial separation. If you get REALLY LUCKY there might be constructive interference, boosting receive signal power. In general though, your comment is unhelpful and your assertions need some backup.

OK - so my 20+ years in RF engineering are worthless then? 1. You can combine received signals from multiple antennas, provided it is done at an IF frequency, not at RF. You can can't just feed all the antenna feeds into a combiner, for example. After reception processing you can select the signal path with highest amplitude. When it comes to transmission, you will need to elaborate because you can't transmit the same signal on multiple antennas AT THE EXACT SAME TIME - it ALWAYS turns into a phased array. There's a boat-load of maths to back me up on that.

comment Hot Copy a vmware virtual machine
The suspend / resume of a VM is usually quite fast - about 1 minute should do it. The copy of the VMDK (virtualised disk) will be the slower part. If copying disk-disk in a machine, 14 GB should be done in under 15 minutes. If copying to somewhere on a LAN it may be slower - depending on all kinds of factors including but not limited to your network speed. A reasonable guess is about 15-30 minutes.

comment Why does my Internet slow to a crawl unless I reboot my router every few days?
I've had the same issue with an old D-link (very old, I no longer use it). The problem causing the issue is best described in technical terms as "dodgy firmware". In other words, there are firmware defects.

comment Random number field code?
I would note however the the original question was about adding a UNIQUE IDENTIFIER to word documents. The thing with this is - is this PER DOCUMENT? Or PER RECIPIENT OF A DOCUMENT? This makes a big difference to what should be done.

comment Random number field code?
In word, you can do this using the algorithm in VBA. The algorithm for an M-Sequence is very easy, provided VBA allows bitwise shift, OR, AND and XOR operations. Its about 10 lines of code. The secret sauce is the magical M-sequence generating function.
