Remember that Floats are not usually exact representations of nice decimal fractions. So most of these numbers are not *exactly* halfway between their possible roundings. 1.15 < (115/100) "true" 1.25 = (125/100) "true" 1.35 > (135/100) "true" 1.45 < (145/100) "true" 1.55 > (155/100) "true" 1.65 < (165/100) "true" In every case except 1.25, the answer is the correct rounding, that, is the one that is closer. For 1.25, the number *is* exactly halfway between two roundings. For round-to-even (which I recommend) the answer should be 1.2, so it gets that one "wrong". Regards, -Martin

There's nothing special about the heartbeat thread apart from needing to have a higher priority than the VM thread. > Isn't possible to run "heartbeat" thread with normal priority and all other threads with lower priorities to provide the same behaviour? This should work provided one can create a thread of lower priority, and providing having the VM thread being lower priority doesn't impact VM performance when other applications are running. IIRC it wasn't possible on the linux pthreads implementation in the 2.4.x kernel dats when I first got Cog working in linux to have a thread at higher or lower priority; there was only one priority available to user programs.

Any new accounts and associated updates since that date are likely to be missing (although the MCZ files will all be present on the server). Root cause of the problem is still not diagnosed, so additional downtime is possible. For reference, here are all of the squeaksource updates that have happened since 5 October. If your name or project appears in this list, your updates may be temporarily unavailable.

Squeaksource.com is down

by David T. Lewis

The squeaksource.com service is down due to a failure in the squeaksource image. Cause of failure and estimated time to fix are not yet known. Recovery may require rebuilding from a backup image from 5 October 2016, so additional downtime and possible loss of account data are likely. All actual files are intact on the server and no data loss is anticipated. Dave

why sparta depends on Taskit?

by stepharo

why sparta depends on Taskit? Since I cannot load it I cannot try to understand. I find strange that a graphical canvas depends on a concurrent task management system. I tried to follow the instruction given by glenn and it failed. So so far I could not see any recent versions of Bloc. I do not understand why the image produced by the jenkins job crashes my vm. Stef wget -O - http://get.pharo.org/60+vm | bash ./pharo Pharo.image config http://www.smalltalkhub.com/mc/Pharo/Bloc/main ConfigurationOfBloc --install=development just failed yesterday for me.

I'd really like, as I told Eliot a long time ago, to have fine control on this sort of choices. Mostly because in low-level libs and performance sensitive code, a 32 bits and a 64bits lib may have a very different API (in terms of structure size, padding and alignment) (and even between versions of, say, a 64bits lib). A C developper is allowed to handle and generate differences by using #ifdefs and __attributes__ and typeof/alignof, including things like that : typedef struct { long long __max_align_ll __attribute__((__aligned__(__alignof__(long long)))); long double __max_align_ld __attribute__((__aligned__(__alignof__(long double)))); } max_align_t; Because a Pharo image (and a package) may be executed on a large set of target platforms / versions, then it seems necessary to me to have the ability to write ourself the code that adapt a FFI interface to the target platform (boiler plate code to detect a target change at image startup, default code for rebuilding the accessors, and the ability to customize that default code).

Re: [Pharo-dev] Instructions for Pharo 6 64bits

by Jan van de Sandt

Hi Esteban, Instantiations is also busy porting their VM to 64bits. They have already created a new API for OStructures so that the offsets are re calculated based on the platform alignment rules and the VM type [1]. I know Pharo is open source and VA Smalltalk is not. But a bit of cooperation should be possible I think. Both platforms benefit if libraries are easy to port and not re-inventing this wheel saves time. Jan.

Newbie(ish) Question on SVG with Athens / Roassal / Spec

by Graham McLeod

Hi I am contemplating moving an old Pharo app (1.4 vintage) which used Morphic heavily into the new Pharo world (Pharo 5). One of the options is to move a proprietary vector graphic implementation which draws symbols to SVG. Looking for examples / documentation on the use of SVG (external files, not image defined paths) has been very frustrating. All examples I have found have been old and none of the file based / load ones work. Can anyone please point me to good documentation / examples? I want to understand how one can use: SVG with Athens SVG with Spec SVG loaded from a file with Roassal Thanks in advance. Graham
