Hi Mariano. Thanks for this. I'm new to Pharo and have been away from Smalltalk for several years (way too long), so right now I am not ready to start debugging the code; perhaps I will return to this when I have recovered my "Smalltalk legs" :) I had hoped someone more in touch with the Pharo project would be able to fix this. Meanwhile, the point I want to emphasise is that this error shows up for anyone working through the Pharo By Example book. Right from the start, the book advises the reader to use a different image file from the quick start one provided with Pharo. Doing this, the reader will immediately run into the "Error:invalid utf8 input detected." problem. This could be enough to put some people off the idea of learning Smalltalk, which I am sure we all want to avoid. Even if they persevere, the impression this gives if that either Pharo is a bit flakey or the PBE book is at fault, or the PBE.image file is bad. Or all of these! As an aside, I would very much like to be able to contribute errata notices and suggestions for improved wording for the PBE book. I have ordered the hard-copy from Lulu.com and will markup any errors and clarifications as I progress through the book. Does anyone know if I can log errata etc online somewhere? --Thomas. -- View this message in context: http://forum.world.st/Error-invalid-utf8-input-detected-tp2068483p2266742.h… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

I cope paste here what I said before: "More in details, the problem is that when you pass an image, it is interpreted as "SmalltalkImage current getSystemAttribute: 1" When you drag a second file (in your case a second image) it is interpreted as source file, not image, and thus the error with the encoding. Put a breakpoint in the method startUpAfterLogin if you want to experiment a bit. At least with this, you know why it was the problem and how to avoid it. Maybe we should raise a better error or even better, if I have already defined an image in the ini file, but I drag another one, override the first one and take the dragged one. I will ask in Pharodev mailing list." So what I recommend you is to put a breakpoint in startUpAfterLogin and start to play. And let us know what happens.

VM/Settings for Deploy

by Sven Van Caekenberghe

Hi, I am very happy that I managed to create a very small deploy image based on Pharo-1.1-11400-rc2. This image contains all of Seaside and Glorp/PostgreSQL and is still only about 12Mb. All this thanks to ScriptLoader's #cleanUpForProduction. Thanks a lot to all who made this possible. I noticed however that this image is handling my HTTP/Seaside benchmark consistenly faster on my Mac, about 80 to 85 req/s (Mac OS X 10.6.4, 2.4 Ghz Intel Core 2 Duo with 4GB RAM) than on my server (RHEL 4 (update 7), 2 Ghz AMD Opteron 175 Dual Core with 4GB RAM), about 55 to 65 req/s. On my Mac I use the Squeak 4.2.4beta1U VM, on my server the Squeak-4.0.3.2202 Unix VM. Next I tried the Squeak-4.0.3.2202 VM on my Mac. This resulted in about 60 to 70 req/s. Is it normal that the Unix VM is slower than the Mac VM ? Shouldn't a Linux server box be faster at networking/IO/CPU than a MacBook Pro running the full Mac OS X GUI ? Is there anything simple (low hanging fruit kind of stuff) that I can do to improve performance, either using command line options to the VM or using settings at the image level ? I currently run the VM with: Squeak-4.0.3.2202-linux_i386/bin/squeak -vm-display-null -vm-sound-null deploy.image What are others using in the Seaside deploy area ? Thanks, Sven

Pharocasts: How to contribute updated + WorldMenu

by laurent laffont

Hi, Learn how to: - choose an issue to fix from the Pharo issue tracking - create and send a slice with your fix - add entries into the World Menu Code must be sent as a SLICE named SLICE-Issue-xxxx-description. Patrick Barroca and StÃ©phane Ducasse have added a +Slice button in Pharo 1.1 to ensure this convention. For more informations on the contribution process, read "How to contribute" on Pharo wiki. Here I show how issue #2582 (Rearrange WorldMenu) has been fixed, based on WorldMenu registration chapter in the Pharo CollaborActive book.
