[ABCdatos] is a large Spanish language software and tutorials directory. We are using POE to enable [our BotLink robot] daily checking to all the outgoing links contained in our directory, ensuring fresh and live operation.


We use POE to monitor, test, and apply changes to several thousand machines. Further, we gather statistics from those machines each minute.


[Cepstral] is an open source speech technology company with a focus on building synthetic voices for diverse use, such as in toys, gaming, entertainment, interactive voice response systems, and dialog systems. They have released a number of audio and speech related modules, which you can browse in the POE Components List.


DomainSponsor [blogged about their POE-based distributed server architecture]. "Today, as a result, we have a large distributed system handling a huge number of requests across an easily-scalable cluster of machines, it’s relatively easy to write new servers using our POE-based framework."


"Formed in 1998, [Dynamic DNS Network Services] strives to provide superior domain name system (DNS) services with the highest levels of redundancy, service, and support in the industry."

POE is one of the [Open Source technologies they use] to achieve this goal., recently acquired by Monster, is India's leading career portal. We wanted to test the site for scalability before launching a major marketing campaign. To simulate a realistic load scenario, a tool was required which could exactly replay an access log at precise time intervals. After unsuccessfully exploring many free tools, we chose to write one in Perl but ran into problems with threads. At this time, we chanced upon [Randal's article on POE's HTTP Client]. Within a few hours we had cobbled up a script with Rocco's help which could do just what was required. This tool is now used for all capacity planning done at JobsAhead.

[Leader.IT] develops Industrial Control Systems using POE.

Viasta, Inc.

Subject: POE

Mr Caputo,

Viasta, Inc is an online platform for video gamers to meet with each other
and play a variety of games. POE has been instrumental to making our
platform reliable and perform well. Additionally, we were able to rapidly
prototype and develop components at a much cheaper cost as opposed to using
C++ or JAVA. We have implemented Server Booking, Game Management, Billing
and Tournament control, all of which are to some degree controlled by POE.

Keep up the great work!

POE's very first application was as part of an internetworked distribution server for a European company that makes market servers. This particular distribution server has been deployed in markets in Germany and Stockholm, and billions of Euros have passed through POE since.

By the way, the POE engine traded 100,000 shares of stock today. Not profitable... not a loss... break-even, but the model is developing.

A Financial Firm (Unnamed)

I've not yet commited my entire network to some sort of giant POE system. However, in my previous employment I was trapped behind a Microsoft Proxy server configured to only deal with NTLM authentication, and I had no way around it. I borrowed chunks of code from Samba and from POE's sample TCP proxy and hassled Rocco a bit, and eventually had a shim proxy that added authentication tokens to regular HTTP traffic and allowed me to skip happily past the

firewall. Alas, I left that job before I'd bothered rewriting the code cleanly enough for general use, but it's sitting on my website in case anyone feels like picking it up:

Note that the comments include disparaging remarks on the nature of NTLM authentication, and the code demonstrates a clear failure to understand anything about POE.

A Game Competition (Unnamed)

I'm using POE to run our school's Counter-Strike tournament. It's AWESOME. You have no idea how much work it saves me. It configures each server at the beginning of each match, sets up practice times on the servers, sets the server to go live, takes screenshots at the end of the game, and reports scores to the SQL database. Considering we'll have close to a dozen servers and one administrator (me), this will help a LOT.


In the game Counter-Strike, I can log events in the game to a UDP socket server. I have my Counter-Strike server logging events to a POE UDP server, which in turn parses them and dumps them to IRC. It's great for matches when spectators aren't allowed.
