If you replace 'single threaded' with 'events based' and leave the assumption of 'just a single thread' out (which doesn't necessarily mean 'one thread per connection'), you can then realize that you can use event based servers... with multiple threads - one per each CPU core, and then you're not limited to one core's power. Some servers are even smart enough to figure out the right number automatically.... http://nginx.org/en/docs/ngx_core_module.html#worker_processes (which happens to be my preferable web server for many years now). And... you can always "why not write an Nginx module in C?"

Details here >From their website: Active Geolocation Project This website is part of a research study conducted by *Nicolas Christin* and *Zachary Weinberg* at Carnegie Mellon University. The purpose of our research is to test ?active geolocation? algorithms. These attempt to determine where in the world a computer is, by measuring how long it takes network messages from that computer to reach other computers in known locations. We test them by making measurements from computers in known locations. We can then compare the position calculated by each algorithm with the truth. We?re also comparing with the position reported by commercial geolocation services (such as MaxMind and Geobytes ) for the computer?s IP address. ---------- Forwarded message ---------- From: Sumana Harihareswara Date: Fri, Jul 8, 2016 at 5:37 PM Subject: Re: [FooCampers] request: run this script on computers worldwide to help research censorship To: foocampers at foo.oreilly.com, zackw at cmu.edu In case you want to spread the word about this request, here's a public URL to use: https://research.owlfolio.org/active-geo/ And you can retweet https://twitter.com/elwoz/status/751403093116542976 : "I'm looking for volunteers to help with a research project: https://research.owlfolio.org/active-geo/ Especially want people outside Europe and North America." -- Sumana Harihareswara http://brainwane.net On 11/04/16 15:34, Sumana Harihareswara wrote: > Foo Campers: my friend Zack needs help in his research to measure > Internet censorship.

I recently started "playing" with controlling simple devices using the PI GPIO pins - trivial things like controlling a LED or servo. I want to experiment with some analog sensors - temperature, magnetic, etc. There are several kits available, but from comments I've read about most of them, they are not "really" meant for the PI and the best way to use them is to connect the PI to an Arduino. I have absolutely no knowledge about the Arduino, but I've seen clones advertised on e-bay for less than $2 - link below. Can anyone tell me if this as actually a working solution and if the low price is actually possible? http://www.ebay.com/itm/1PCS-Pro-Mini-atmega328-5V-16M-Replace-ATmega128-Arduino-Compatible-Nano-/152160908037?hash=item236d7f3305:g:MMcAAOSw2GlXLD~U -- Shlomo Solomon http://the-solomons.net Sent by Claws Mail 3.11.1 - KDE 4.14.5 - LINUX Mageia 5 From write.to.jason at gmail.com Sun Jul 31 09:03:15 2016 From: write.to.jason at gmail.com (Jason Friedman) Date: Sun, 31 Jul 2016 09:03:15 +0300 Subject: Raspberry PI - analog sensors with Arduino In-Reply-To: <20160731085048.0be080e9@shlomo1.solomon> References: <20160731085048.0be080e9@shlomo1.solomon> Message-ID: > > I have absolutely no knowledge about the Arduino, but I've seen clones > advertised on e-bay for less than $2 - link below. > > Can anyone tell me if this as actually a working solution and if the > low price is actually possible? > > > > http://www.ebay.com/itm/1PCS-Pro-Mini-atmega328-5V-16M-Replace-ATmega128-Arduino-Compatible-Nano-/152160908037?hash=item236d7f3305:g:MMcAAOSw2GlXLD~U > > Arduino is probably the easiest / cheapest way to access analog sensors. While quality of these do vary, I have had good experience with these very cheap units. Note that you need to program these devices via a USB cable and an FTDI programmer (you can also find one on ebay for a few dollars). I would recommend for someone new to Arduino that you get an Arduino uno / sparkfun redboard (or a chinese clone of one of these) - they have the programmer built into the board (so you just plug it via USB to your computer). They also have headers soldered onto the board already, so you can connect sensors, LEDs, etc without soldering, which is good for getting started.

In the meantime, I've done more research, and I see that there are several ADC (analog digital converter) chips available to help the PI use analog input. Since my main purpose is to learn to use and program the GPIO pins on the PI, I guess that would be a good solution - especially since my C++ skills are REALLY rusty and I'm much more comfortable with Python.
