Despite not knowing him personally his name appears a lot in the Squeak mailing lists and in a lot of packages. When I saw this message I thought he passed away earlier and this post was to commemorate the event, not knowing that it was all so sudden. I am sure I will miss his presence and any contributions he would have made if we was still present with us. My condolences to his family.

[Pharo-project] Smalltalkhub project deletion
by Camillo Bruni Jan. 15, 2013

Jan. 15, 2013

I just tried to delete my project to wipe out all versions, but it looks like that the versions all re-appear after you create a new project with the same name as the old one. Is that on purpose? best cami

[Pharo-project] New Cog VMs available
by Eliot Miranda Jan. 15, 2013

Jan. 15, 2013

...at http://www.mirandabanda.org/files/Cog/VM/VM.r2672. CogVM binaries as per VMMaker.oscog-eem.255/r2672 [New[Co]]ObjectMemory: Fix becomeForward: so that objects whose references are deleted are freed and can no longer be resurrected via allObjects or allInstances. Remove freed young roots from the rootsTable. Filter freed objects pointed to from the extraRootsTable (because these locations can change it is wrong to remove entries from the extraRootsTable). Make primitiveIdentityHash pop all arguments, for Newspeak VMMirrors. StackToRegisterMappingCogit: Fix marshalling of absent receiver sends. The items beneath the arguments (and to-be-pushed receiver) must be spilled before the receiver is pushed. Improve code quality for numArgs > numRegArgs sends when receiver is not a spill and there are no uses of ReceiverResultReg amongst args. e.g. now avoids loading ReceiverResultReg from stack in code such as 1 with: 2 with: 3. -- best, Eliot

Dear friends in both Squeak and Pharo communities, I am stunned but felt I just had to write something on this day and I am CCing Pharo because in the end we are all the same community in my book. Andreas was so young and had just started the next chapter of his life together with Kathleen. Now, there are other people in this community who knew Andreas much better than I did, but I still want to write something, especially perhaps to you who aren't that familiar with Andreas and all the work he has done for us. Andreas was *exceptionally* bright and above all perhaps the single most *productive* Squeaker in our community - we use lots of his code every day. In a Squeak 4.4 image there are 6382 methods with his developer initials currently on them touching in total almost a thousand classes. And this is more than *double* the amount of methods as the second developer on that list. And since this is just based on the latest version of the method, his legacy is even bigger in reality. "Top thirty method touchers" ((CompiledMethod allInstances collect: [:m | m timeStamp readStream upTo: Character space]) asBag sortedCounts first: 30) "Classes touched by Andreas" (CompiledMethod allInstances select: [:m | (m timeStamp readStream upTo: Character space) = 'ar'] thenCollect: [:m | m methodClass]) asSet And even in Pharo 1.4 his mark is still there with almost 3000 methods touching almost 400 classes, this places him at *fourth* place. And of course he wrote the Windows VM and was an instrumental developer of Croquet/Teleplace and much, much, *much* more. Now, we have a few VM developers who are very good at those parts. And we have developers who are very good at selected areas of the image level. But people like Andreas who work on *all* levels of Squeak, from the VM and all the way up to 3D and stuff like Croquet... well, we don't have many and at the moment I am not sure I can think of anyone with the same span as Andreas had. I only met him a few times, at OOPSLA I think and once he visited Stockholm and we had some time hacking and talking about Squeak and how to grow the community and so on. He cared quite a lot about the community, perhaps more than most people thought. Two years ago Andreas contacted me for some contract work for Teleplace and he was as always very sharp, friendly and helpful in getting me up to speed and being involved although I was sitting here in Stockholm. We had some late night Skype sessions digging deep together in odd network protocols and it was in the middle of one such session, about 2 years ago that I asked him: Me: And hey, Eliot gossiped that you ... met someone? :) Andreas: Yes, indeed. Madly in love as they say :-) Life is just not fair. This is a very sad day. GÃ¶ran

This news are really shock for me. Shock because we lost one of the brightest Smalltalkers who contributed to our community a lot.

[Pharo-project] Zinc timeouts
by Camillo Bruni Jan. 15, 2013

Jan. 15, 2013

I am trying to make the .sources downloads more stable and give proper feedback. I ran into the following problem with Zinc: | client | (client := ZnClient new) numberOfRetries: 1; timeout: 5; ifFail: [ :e | "ignore" ] url: 'http://an.url.that.does.not.exists.ch/foo'; downloadTo: '.' asFileReference; close Running this code hangs the image indefinitely (so far > 2min). Actually I would like to put #numberOfRetries to 0, since I want to fail as soon as possible during startup. However putting that the retry count to 0 yields an Exception caused by #downloadTo: ZnClient(Object)>>error: "Request not yet executed" ZnClient>>isSuccess ZnClient>>downloadTo: If I omit the #ifFail: block I get a warning about the wrong url, which is of course not what I want during startup? Is this a Zinc bug?

[Pharo-project] PasswordHashingFFI package - users should update
by Paul DeBruicker Jan. 15, 2013

Jan. 15, 2013

Hi - I was using a basic string comparison in the #checkPassword:against: methods and I now understand that that is susceptible to a timing attack on some systems (http://codahale.com/a-lesson-in-timing-attacks/) I'm not sure these types of attack apply to Smalltalk environments or not but its not hard to implement a constant time algorithm. Instead of failing on the first unmatched character it reports passing/failing after checking all characters in the hashes. I think the new version is not susceptible to the timing attacks mentioned in the linked article and if you use the package mentioned in the subject you should update to the latest version. Thanks Paul
