Dear sir, Am student in master 2 in computer science department in the university of yaoundÃ© 1 and for my master thesis, i have to build an anomaly detection algorithm for a network intrusion detection in pharo.i have started reading about pharo. And i have the following question in mine - How can an application develop in pharo be deployed(web application and stand alone application)? - How can i capture frame and packet in a network using pharo? Best Regards, Arnaud

Highly depends on what kind of application you develop (installable rich client or web application for deployment on a user machine or a hosted system using a cloud provider) Some pointers when you deploy for a machine installation: http://zn.stfx.eu/zn/build-and-deploy-1st-webapp/ https://pharo.fogbugz.com/?W78 http://pillarhub.pharocloud.com/hub/demarey/ez5m8nnaojww0rrnvnih9l4uy http://lists.gforge.inria.fr/pipermail/pharo-project/2010-February/021450.h… or hosted somewhere like on Pharocloud https://www.pharocloud.com/kb >How can i capture frame and packet in a network using pharo? you need something that intercepts network communication. https://www.wireshark.org comes to mind. You could possibly bind directly to libpcap (a portable C/C++ library for network traffic capture that is used by Wireshark) using Pharos Universal FFI. There is also WinPcap for Windows. Bye T.

STON materialization corrupts a dictionary if the keys are references
by Peter UhnÃ¡k April 5, 2016

April 5, 2016

Hi, I ran into a problem with STON that seems to corrupt on materialization. Consider the following script: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ c := OrderedCollection with: UUID new. d := Dictionary with: c first -> nil. o := { c . d }. s := STON toStringPretty: o. o2 := STON reader allowComplexMapKeys: true; on: s readStream; next. o2 second keys. "an Array(an UUID('571bbfb7-78b9-430c-9aad-3e0088a25f4c'))" o2 second printString. "KeyNotFound: key an UUID(''571bbfb7-78b9-430c-9aad-3e0088a25f4c'') not found in Dictionary" o2 second at: o2 second keys first. "the same error" ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ So even though it contains the key it fails to access it. Interestingly enough if I serialize and materialize the "broken" dictionary again it suddenly works again. Thanks, Peter

SMTPClient further - kind of answer
by Robert Kuszinger April 3, 2016

April 3, 2016

Hello, A few days ago I've posted an SMTP related question about timeouts. (SMTPClient sending). I was able the repeat the situation on Linux as well with Postfix SMTP server on the other side (The original question was Windows / Exchange Server) Now smtp works and there are two consequences, at least for Pharo/Seaside beginners like I am :) - Using Halt for debugging in such a Seaside project when sending SMTPClient emails could make this timeout. It waits for signal not coming and it maybe related to timeout handling inside what I don't understand. If you face SMTPClient timeout in the DATA phase of sending an email check if you are debugging (in debugger window, using halts, etc) and try without that (eg. Transcript show: logs or something else to check what is going on). - Pay extra attention to email mime type and content encoding including subject string of the message. Since I'm sending hungarian language emails it was essential. Server answers and sensitivity on exotic email messages depends on the SMTP server implementation in question, but staying minimal on smtp fields is always a good idea. Specify To: and From: fields in the DATA part also. When I created correct email DATA part with correct encoding and removed debugging from the Seaside application code (so debugger was not active when run into SMTP sending) emails started to go out with no problem. good night R
