Most TI-8x graphing calculators have a serial port over which programs can be sent and received. The connector is a 2.5 mm jack, which looks like a headphone jack but narrower. The user connects the devices with the appropriate cable, chooses "receive" on one device, and chooses "send" on the other. One thing that can be sent over such a link cable is user-entered programs. If a calculator emulator emulates the serial port, then it can receive programs not approved by Apple over the emulated serial port and thus violates the policy that you have quoted.

That's what I was talking about.

It's hard when the user can't touch-type code because an update to the device's operating system has caused it to misdetect the user's Bluetooth keyboard as a "nonalphabetic keyboard" (that is, a gamepad). Android 4.3 does this for all keyboards that use a specific Broadcom chipset, such as the ZAGGkeys Flex, and the device's owner can't fix it without wiping the device to root it.

Anything big that one would send over the wire, such as zipfiles, image files, audio files, and application installers, is already compressed. Modems won't increase compression.

Is an Android device "a computer" in this sense? Either way, it still doesn't matter because AIDE allows for programming directly on an Android tablet, provided that the Android 4.3 update didn't disable your keyboard. (The workaround works only on rooted devices.) On the other hand, each student would have to carry both an iPad and an Android tablet: an iPad to read the iPad-exclusive textbooks on which the district has standardized and an Android device for programming.

Because under the policy of at least one school, any handheld device running iOS or Android would need to be placed in the student's locker no later than the first bell and removed from the locker no earlier than the final bell. Exceptions can be made for students using special education services on the student's Individualized Education Program.

That and a $120 calculator per child is much less expensive than a $400 laptop per child, even with the economic rent that Texas Instruments collects for being accepted for use with College Board tests, and somewhat more durable.

Where is the updated version of the information that doesn't require first paying $99 for the first year? About six months ago, I was considering developing applications for iPad, and I was considering buying a sufficiently recent Mac on which to run Xcode and an iPad mini on which to test my application. Before committing to the hardware purchase, I wanted to view the App Store Review Guidelines to make sure my application concept would be permitted, but a free Apple developer account wasn't enough to view the Guidelines.

Which means any emulator would fail because it would lack support for the calculator's serial port.

I'd imagine it compares to the upgrade from DEFLATE (used in PKZIP and Gzip) to LZMA (used in 7-Zip). As I understand the claim being made, the original algorithm compressed a representative corpus of data to 50% of its original size and the new algorithm 40%.

But how easy is it to replace the rechargeable lithium ion batteries in these tablets? Most laptops from the Windows 9x era have removable batteries.

I thought there was a "mom's basement" stereotype against adults who live with family other than spouse and children. In addition, some careers tend to be concentrated in cities where one might not happen to have family. For example, good luck working for a U.S. video game developer and living with family if you happen not to have family who live in Austin, Boston, or Seattle.

If the distribution isn't skewed enough to push the mean a measurable distance away from the median, then yes, that is how averages work. Show me that the mean and median of a large human population's intelligence differ to a noticeable extent, and I'll agree with you.

It doesn't take a health club membership to do sets of push-ups and body weight squats in front of your TV. Even chin-ups are without charge at a nearby city park.

When Mozilla Application Suite (now SeaMonkey) and Phoenix (now Mozilla Firefox) were first being developed, there was no such thing as Visual C++ Express.

There's no legal obligation. But requiring a paid compiler, as Mozilla did before Microsoft introduced Visual C++ Express, does shut out much of the public from participating.

I'm not so sure of the extent to which Microsoft allows Mozilla to distribute "the scripts used to control compilation and installation" of a Windows 8 style (formerly Metro) application such as Metro Firefox, especially when such "scripts" may include private code signing keys.
