In its current state, it grabs analog data from an ADC, and dumps it into memory on the BBB, ready to be displayed or further processed. It could be used for gathering analog information from sensors, CCDs or other data acquisition use-cases. To be reasonably useful, the desire was for it to support 20Mbytes/sec of data or more. It does achieve this, but it is for further study to find higher speed methods.
BeagleLogic is a logic analyzer realized using the Programmable Real-Time Units on board the BeagleBone Black and the original BeagleBone. The core of the analyzer is built using a kernel driver that exposes a character-device interface at "/dev/beaglelogic" which can be read out to receive captured data.
Easy tips and tweaks for Linux Mint and Ubuntu, both for beginners and for advanced users!
Vital personal and business information flows over the Internet more frequently than ever, and we don't always know when it's happening. It's clear at this point that encrypting is something all of us should be doing. Then why don’t we use TLS (the successor to SSL) everywhere? Every browser in every device supports it. Every server in every data center supports it. Why don’t we just flip the switch?
The StartSSL™ Free (Class 1) certificates are domain or email validated and mostly referred to as the free certificates. Because the checks are performed mostly by electronic means, they require only minimal human intervention from our side. The validations are here to make sure, that the subscriber is the owner of the domain name, resp. email account. You may find additional information on this subject in our CA policy.
meSpeak.js adds support for Webkit and Safari and introduces loadable voice modules. Also there is no more need for an embedding HTML-element.
Separating the code of the library from config-data and voice definitions should help future optimizations of the core part of speak.js.
All separated data has been compressed to base64-encoded strings from the original binary files to save some bandwidth (compared to JS-arrays of raw 8-bit data).
Browser requirements: Firefox, Chrome/Opera, Webkit, and Safari (MSIE11 is expected to be compliant).
So the case in point is identifying which token to parse next. There are a few ways to go about this. My first attempt was flimsily checking the first character or two and making decisions based on that. I then did some tests with regular expressions and it turned out to make things a lot faster. It cut my parse time at the time back in half! Just for reference, this is the regex that it uses:
A recent storm with horrific winds took down our electrical power. The outage was widespread, straining the power company to get everyone back online. We were without power for almost 3 days - no heating, no hot water, no refrigeration, no range, no microwave, no lighting. No TV, no WiFi, and no hot coffee in the morning. And we were the lucky ones; many were blacked out for over a week. Time for a backup plan.
Here's a cheap way to build your own fully customisable infrared PC remote control. If you already have a suitable infrared remote control going spare you can
For a while now I've been toying with the idea of using the proximity effect of capacitive touch buttons to track motion, which can be used to create a intuitive "touch-less" controller. Such a controller could be used to replace light switches in hospitals where the spread of germs is a serious concern. Also could be used as a cool futuristic light switch for the home. The device would do away with mechanical switch's which wear out over time, and is replaced with solid-state relays coupled with a microcontroller's intelligence. I will add network connectivity so the device/devices can be used via a smartphone or tablet over your local network and abroad. With the use of touch-less hand gestures or your smartphone's app/browser, the controller can be used as a classic toggle switch, multiple switches, a dimmer, timer or any combination of these on anything you feel like controlling.
