Thanks for the script, it is very useful :) By running it, I get: Not spur image: 1143.0 Mo Spur image: 1140.1 Mo We are far than the 2Go... even for spur.

The stream API is too wide, people expect hundreds of methods to be there, mixing characters and bytes, encodings, line end conventions, infinite buffering, arbitrary positioning, and so on. Many of these characteristics can be elegantly composed, just when you need then. Right now we have some cool streams in the image, with minimal APIs, targeted at just one function.

But in a deployed application on windows for a Synectique customer they use 2Gb and sometimes windows doesn't want to start the app, as a work around they found out that windows always agrees to start the app just after being reboot. So the .ini file is good on Unix to allow 2Gb instead of the default 1 Gb, but on windows there are additionnal problems.

Hi sven I would like to get Xtreams (with a slightly modified API - no ++ and --) in Pharo 6.0. So I hope that we will be able to clean the stream part of Pharo.

Re: [Pharo-dev] MemoryFileSystemFile>>#readStream forces String

by Max Leske

We introduced #binaryReadStream and friends as a work around in Pharo 4. The reason we didnât fix the problem properly is that weâve been waiting for the introduction of XStreams in hopes of getting a cleaner stream API.

Great to hear. Coincidentally, I heard about the Pi3 last night and ordered one due to ship 7 march. Built-in wireless and more GPIO pins are nice. I found an interesting comparison of ARM A7 and A53 http://www.anandtech.com/show/8718/the-samsung-galaxy-note-4-exynos-review/3 Also I was suddenly disappointed that I had bought a Pine64, but I was happy to read this balanced report that it retains some advantages... http://forum.pine64.org/archive/index.php?thread-379.html cheers -ben
