They have ieee1284 printer-port protocol baked into them, so you do an OUT transaction of several bytes and the adapter does the per-byte handshaking. The old parallel ports were just a collection of gpio lines (originally some input-only a

Sounds like if Acme Telecom resells Google's service, and a cop has the number of an Acme subscriber, Google will put the cop in touch with Acme.

MIPS, the Microprocessor without Interlocked Pipeline Stages, doesn't make sure the result of one instruction is available before executing an instruction "later" in the stream that refers to that result. Something like (pse

The lock-powered-by-key exists: http://www.cyberlock.com/access-control/cyberkey-smart-keys . The power and signaling go through metal contacts rather than wirelessly.

In many applications, crashes are less of a problem than falsely believing a write happened persistently. Consider a mail server: if it can wait until the message is really saved before returning the final success response, then a crash mea

For those who haven't had a physics class, that's garbage because silver is somewhat more conductive than copper, which is slightly more conductive than gold. The main benefit of gold is that it's more stable than copper, so

Newer systems using 3GPP-type authentication (LTE, and I think UMTS) require mutual authentication between the SIM and the network (details in [1] section 6.3). If the network doesn't provide a satisfactory AUTN, the mobile can't

Confirming you can feed a .sln file to msbuild (I did it the other day), no idea about whether nmake accepts them. Source: https://www.wireshark.org/docs/wsdg_html_chunked/ChSetupWin3... .

Just redirect gpg's input from the file? gpg ... < hello.txt | curl ... Its stdin will be the file instead of a pipe, but few programs care about the difference and fewer still in such a way that you'd prefer to use th

A sim card gets to send messages to the baseband in response to requests from the baseband. It doesn't have arbitrary memory access unless the baseband has really nasty bugs.

A "short-lived victory" isn't what it used to be. Local production started 45 years after the first shipment; sounds pretty good in modern terms.

Gmail also supports you.r.nam.e@gmail.com (add random dots to the local-part). (Almost?) every system considers '.' a valid character. However, you need to keep track of which tagged address goes to what service, much like the ca

These programs can't do much that the carrier couldn't do without your help: set up calls, send/receive SMS/USSD, sort of thing. It's not as if they ran on the application processor as root or had DMA to the app pr

The SIM in 3G isn't really much like a DRM thingy, apart from containing a key; it's more like a securid keyfob. The only interesting thing it does (apart from storing constants like its serial number and variables like your phone

add ix iy I'm pretty sure that isn't a thing (the z80 has prefix opcodes for "hl in next instruction is really ix (or (hl) is (ix+dd)" and one for iy, but not one for both in the same instruction like that). So

Because of that feedback, you get to use your load as the lower half of the divider, so the total current drawn from the source is the load current plus a few microamps for the regulator's internals. In the passive voltage divider circ
