Thank you very, very much to Carol Foil (dermoidhome) for the identification of this hummingbird!
Listen its song in the site Xeno-canto, at the address www.xeno-canto.org/species.php?query=Colibri+serrirostris
A text, in english, from the site Birdlife Internacional, that is at the following address: www.birdlife.org/datazone/species/index.html?action=SpcHT...
White-vented Violet-ear (Colibri serrirostris)
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence 30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
Family/Sub-family: Trochilidae

Server - an eeePC 701 with 2GB memory and a 100GB external 2.5" USB-powered hard drive. It boots Fedora 9, so the "standard" Xandros-based eeePC software hasn't been touched, and it still works just like a netbook if you want it to.
It does web serving (blogs, photo gallery, etc), mail server (incl webmail), web proxy, media serving, system monitoring and other similar duties quite happily, and draws a fraction of the power of what we used to use. Think of all the carbons we're saving....

This is my new web server, Its running Fedora 15, with Apache MySQL and its running my blog on andrewgomes.net.
the wiznet module (red) is a whole IP stack on a tiny board.
I've run the demo webserver app and it really works!
the grey cable is usb and used only for power (gives the circuit a nice 5v).
the yellow cable goes to my network switch/router. when you ping or web-connect, you can see the yellow LED blink! way cool.
just a proof of concept, really; but in development is support for a simple 'get/set' serial protocol to manage the volume control/preamp system.
in this test, I installed apache on a linux box and connected the linux system to the arduino via the very standard FTDI usb/serial cable. the arduino runs some serial i/o code that responds to requests from the host (the linux webserver). when the user connects to this CGI, it takes the volume up/down request (the arrow keypad) and sends that change request to the arduino, waits for its reply and then dynamically recreates the LCD display in a 'real view' fashion. even the bargraph is true to life.
from any room in the house, you can now vary the volume and address as many of these units as you have /dev/ttyUSB cables for ;)
(note: the colors are actually RGB values for foreground and background and are really stored ON the device! when the management station queries the device, it gets its 'name', its 'location' (8 byte strings) and also the fg/bg colors that the user entered at config time. the web GUI then uses that to draw the LCD colors. it makes it very easy to know, at a glance, which unit you are really talking to.)
the hardware that is running this:

its called an LCDuino-1 and its an arduino-based audio controller for DIY use. more info on the project: www.amb.org/forum/lcduino-1-display-i-o-processor-f21/

I knew something was a bit awry this morning when I polled for my email and didn't get a response. Then I noticed that one of my network shares wasn't active.
My first guess was that we'd had a power interruption during the night and the server had shut down. This was reinforced by my inability to telnet into it. Then I fired a ping request and surprisingly got responses.
This meant a trip down to the cellar to investigate.
Eek. The server was reporting disk errors. I tried to log in to see what was going on and it wouldn't prompt me for a password. Not good. The only available option for a forced power down and reboot. It got as far as the GRUB loader and then crapped out. Primary system drive failure. Bah.
The good news is that the large filestore array looks like it will probably be intact. The photo shows the replacement system drive, and I've carted the lot round to Dave for a recovery assessment. The server didn't actually do that much - with the security cameras on a dedicated unit it was really just a webserver and email box. Rebuilding from scratch will be bloody inconvenient but not really do or die (otherwise it would have been on a mirrored drive).
We'll see if we can get anything back. It's just come at a bad time. Ah well.
Web host are the companies that provides space on a sever they own for use by their client as well as providing internet connectivity, typically in a data center. It can be view by other net users as well.
Brian Behlendorf, inventor of the Apache webserver (and original technologist for the Burning Man festival) is onstage at CloudFest 2019 to talk about using blockchain to return power to everyday users. He sees the blockchain as a living thing, capable of breaking up the silos that tend to erect in set-in-stone networks.

The actual machine that hosted the very first web server in the world in 1991. This is Tim Berners-Lee's computer at CERN. Interestingly, it's a NeXT Cube; NeXT is the company founded by Steve Jobs after he was removed from Apple. Talk about making history with history!
If you run a forum you need CloudFlare! By reducing malicious visitors (web spammers, botnet zombies) and caching my site on its distributed servers, it decreased the CPU time that my forum consumed by over 50% as you can see by these two charts. The top chart is the "GPU" usage on my Media Temple account. A GPU is a measurement that derives from CPU time required by every single hit/request made to a (gs) Grid-Service - including web server activity, programs, scripts, etc. OLPC News Forum was consistently 50% of my overall usage and had me go over my allotment on occasion (continuously using +20% of a processor core per month). Now with CloudFlare you can see that usage drop at the same time CloudFlare took over.
Thanks Cloudflare, and thanks to Media Temple for offering CloudFlare for free to all its customers.

yes, there is now a webserver inside my 'volume control' (actually its better described as a stereo preamplifier).
point your browser at the preamp's IP address (lol) and you get exactly the same display as you'd get if you were in front of the physical box.
the web graphics were created by xpaint and converted to base64 for inlining (!) in the html code that the arduino sends out.
The Mag-Net project file server. This pioneering file server helped bring together a community of educators in the 1990's. It hosted a webserver, mailing lists and a suite of experimental projects that included a data logger, web camera, online quiz and more. This was before Department of Education even had its own website. For some educators including this author, it was their first serious Internet e-mail address. The file server was powered by Linux and located in the basement of the Education faculty of Monash University, Clayton Victoria. These photographs were taken when the final Mag-Net file server was finally decommissioned in 2001 and perhaps ungraciously stripped for parts.
This is the third and fourth generation of the hardware. Originally it ran on just the HP, then I added the cheap dell for a frontend webserver
Yay! I finally have a nearly flat signal graph for a whole day! Things have been so unstable in the past month or so that I've scarcely gone more than six hours without some sort of weird rise or drop in signal strength.
I made a Perl script to connect to the little webserver at 192.168.100.1 on my cable modem and read the signal data, then ran it through the rrdtool graphing program.
Blue is transmit power. The red line is at 54 dBmV, which is roughly the maximum allowable transmit power on modern DOCSIS, though I think my cable modems have occasionally gone to 55 or 56.
The orange is receive power. This is generally supposed to go between +8 and -8 or +9 and -9 dBmV.
The green line is signal-to-noise ratio (barely visible here since it's on a white background on this particular graph). SNR doesn't really seem to be a very good measure of cable modem signal quality, since it barely moves despite big changes in receive and transmit power.
Where my digital life is at.

Webserver running on my RaspberryPi and reading ambient temperature via a 1-wire sensor. 10.31.2.151/cgi-bin/temp.py for those in the lab.
2 external harddrives totalling 1.5 TB of storage, one FW400 and one FW800.
The FW800 1TB MyBook is my current TimeMachine drive. The 500gb MyBook is used for other storage, usually for near-line retrieval of movies, archived music. I also use it for paranoia safe back ups such as school work, in addition to my webserver, dropbox, and Time Machine.
I've lost data before and I don't want to do that again.
Now with actual rack. The application servers are hosted with Rackspace, this is just the in-office stuff. At left, the dev server, office webserver, firewall; at right, the comms rack.

this is cool stuff.
my arduino and ethernet shield can now remotely control my computer based music player.
the config: apache, php, phpMp2, mpd on the linux server. that provides a webserver (apache), the webserver app (phpMp2) and the audio decoder/player (mpd). all formats are supported, mp3, flac and so on.
on the client side, you simply connect to the webserver (apache/php on the linux box) from the arduino and send formated GET requests, like the one shown in the white program edit window. the black run-display window shows the actual dialog, character by character, in requesting that the next song in the playlist be played. all replies are in the 'pound' format that I developed which is just a simple tagged method of getting data quickly.
the arduino parses that 'pound stuff' and displays song name (etc) info to the lcd screen. when the user presses a NEXT or PREVIOUS or PAUSE remote key on the IR keypad, the corresponding html GET request is sent to the server and this causes the song to be paused or played or whatever.

arduino and lady-ada ethernet shield talking to a webserver that talks to 'mpd' sound daemon.
the arduino is now in a metal box, for shielding (noise) purposes.
we can even run the squeezebox SERVER on this little seagate dockstar linux board. amazing. it has its own mysql database and webserver.
