Comment: Interactivity? (Score 1) 164

I wonder how much advantage of the medium a PC version of a TV series will be able to take... I''ve been homeschooling my kids whilst we've been travelling so I've tried a number of these online reading tools. Some are just a mess of unindexed content, or just libraries to wonder in and pick out books to read or subject videos to watch. The best for my 5 yr old has been ReadingEggs which has heaps of interactive mini games joined together into an overall programme that the child can follow through themselves going right from pre-literate to reading age 7 or so.

Has anyone used the iPad app of this Reading Rainbow program? What's it like ? And how much teacher support is needed?

If you knew how the old game controllers worked and what the driver had to do to read from them you would be glad they're gone. See my earlier post for some hideous detail.... You can buy adapters to USB which are likely to provide much better stability (and not need calibration constantly) and will work with windows 7, though I haven't tested with the Cyberman.

Drifting off topic, but if we're talking the gaming ports, they weren't serial. They were much, much worse. The joystick potentiometers were connected across pairs of pins in the connector, but then, instead of just making them an input to a DAC or something simple they were basically hooked up as the variable resistance on a 555 microtimer so that the position could be read by triggering the timer and counting how long it took to drop back to it's base state. I know DACs were expensive at the time it was designed, but this choice led to some programs having to busy wait to measure, endless issues with different processor speeds needing to be compensated for, and the requirement to regularly "calibrate" the joystick in each game. I suspect the chances of that precision timing working well on a multi core, variable speed CPU with a real (preemptive) OS and possibly a VM in the mix too, is small.

A USB device that works as a DAC and pretends to be a modern joystick interface would probably improve the controller no end.

And yes, I bought a joystick just to play Descent too. But a simpler one than the GP.

Their best proposed solution is to ban Yahoo email users from mailing lists and encourage them to switch to other ISPs

What the #%^+? Since when is Yahoo an ISP?

Several ISPs outsource their customer email service to Yahoo. If you're with one of those, and especially if you use your ISP provided email address, then moving would fix it (or just move to gmail/, you're mail is in the cloud now anyway, since your ISP moved it there)

Yeah, I often think Apple could make a great iPhone Nano, similar size to the iPod Nano, thicker for battery, etc, just like the iPhone / iPod touch, with just basic, simplified apps to show calendar perhaps preview, but not write email, etc. A kind of up-market feature phone, or just as an iPad companion...

Xirrus have been doing this for years - see or

They put 8 (or more) access points into a single unit, each with a directional antenna covering a segment of the room or venue. I looked at their product at a trade show or conference once (don't remember which) but it was way overkill for the spaces we had at the time which were separated with heavy reinforced concrete walls and floors, so needed an access point for each area.

Comment: Re:56 Kbps of landlines voice quality is noticable (Score 1) 329

by Adrian Harvey (#42659683) Attached to: When Was the Last Time You Used a Landline Phone?

IIRC it wasn't 1 bit in each byte/octet, but one from every 6th octet. This meant that or voice it was still 'almost' 64 kbps ... Let's see... 64 - (64 * 1/48) is 62.66... But because a modem can't synchronize, so it can't tell which bit is going to be robbed, it has to assume that but is always used, so you get 56 kbps.

Although this (bit robbing) was mostly a North American thing 56k was still the top speed modem I ever saw...

I've found much more detail here.
