Are there Chi-Square, Power, Normal, Binomial, Uniform, Student's-T etc distributions ?
by Paul DeBruicker March 31, 2010

March 31, 2010

Hi - Is there a standard library access and make calculations from the distributions mentioned in the subject of this email? I'm interested in random draws from those distributions. I haven't found anything looking in the image or on squeaksource. Thanks Paul

[GSoC] Problems, Students bio and projects without mentor
by Mariano Martinez Peck March 27, 2010

March 27, 2010

Hi everybody. I hope everybody is fine. As you may have noticed, the ESUG GSoC has been quite busy the last weeks. Students started to register in the website, discuss with mentors, etc... A little problem that we saw few times: when you register (as a student or mentor) you should receive a confirmation email. I don't know why but some people reported this mail was filtered in the spam folder. So, if you are mentor or student and didn't receive a confirmation email, please check you spam folder. Students, when you edit your profile there is a tab called "Biography". Please, take the time to complete that. There are multiple students per project and that may help the mentor to choose the student. Another problem is that we have two projects without mentors. 1. Native windows for Squeak and Pharo http://gsoc2010.esug.org/projects/native-windows 2. OpenSSL Smalltalk wrapper http://gsoc2010.esug.org/projects/openssl Fortunately no student yet expressed interest on any of them. There is a deadline in Monday to remove them if there won't be any mentor found. That's all for the moment. Mariano ESUG GSoC admin esug.gsoc.adm2010(a)gmail.com http://gsoc2010.esug.org/

using weak collections
by Yoandy RodrÃguez MartÃnez March 25, 2010

March 25, 2010

Hello again: I need to create an object's registry that keeps certain objects in a dictionary and a second registry that keeps only objects currently in the first registry so i thought it was a good idea to user IdentityDictionary and WeakIdentityKeyDictionary so when the any object in the first registry is removed then the second registry remove's it too. Problem is that when i try to test my code, the second assertion fails. Is there anything wrong with my test or weak collections are not suppose to work like that? ColonyTest>>testWeakRefs |registry anotherRegistry object | registry:= Registry uniqueInstance. "this keeps weak references" anotherRegistry := Colony new. object:= ColonyMember new. registry register: anotherRegistry. anotherRegistry addMember: object. registry register: object. "object is into the second registry" self assert:[ anotherRegistry contains: object]. "if we unregister this reference then the registry should lose it too" registry unregister: object. self deny:[ anotherRegistry contains: object]

[GSoC] Call for students
by Mariano Martinez Peck March 24, 2010

March 24, 2010

Dear Students, Now it is your turn! You will have to register in our website, put there some information, show interest for the projects and contact the project mentors. After the registration step you will get all the mentors information in order to contact them. By pressing the button on the project, you will show your interest. This is not something formal yet. Our mentors will vote for the most interesting projects and in the middle of the voting Google will tell us, how many projects will actually be funded. Voting will happen in April, with final results expected at the end of April. At that time you will finally know if you are accepted or not. Of course, there can be many students interested per project. This means that interest for this project is high, but on the other side a chance that you will be chosen is lower. It is up to you to convince a mentor that you are the best! Note also that the Ideas page is deprecated. On ideas page just the project ideas were collected. Now, we are preparing the real projects. So, please from now on always refer to this link for the projects: http://gsoc2010.esug.org/projects So, the initial steps are: 1. Register on our special Smalltalk GSoC website: http://gsoc2010.esug.org/registration 2. Edit your profile to get some more contact information for mentors to let you know, 3. Fulfill your brief Biography page (see Biography tab on profile), 4. Go to Projects page, choose up to three projects and click there I'm interested button, 5. Contact and discuss with project mentors about your interest. You will be also subscribed to a special mailing list [1] where we will help you with further steps. Deadline: as soon as possible, because the deadline to register on official GSoC website [2] is 9.April, which is, well, soon! But about that later... Finally, we will really appreciate if you can help us to distribute this call for students. One of our goals is to increase the Smalltalk community. Those who have access to universities can distribute this among the students.

Dynamic Bindings
by Yoandy RodrÃguez MartÃnez March 23, 2010

March 23, 2010

Hello everyone I've just started in the Smalltalk world and recently moved to Pharo after trying a little Squeak (mostly e-Toys). I want to promote the use of Smalltalk solutions but there seems to be no books on the subject besides Squeak and Pharo by Example. Can anyone point me to any recent book about Smalltalk?

[GSoC] Call for mentors!!!
by Mariano Martinez Peck March 23, 2010

March 23, 2010

Hi folks. We wanted to let you know that we are calling for mentors. As you can see in the ideas page: http://gsoc2010.esug.org/ideas There are some projects that still don't have mentors. Furthermore, it would be GREAT if each project can have also a second mentor. This is very important as they can complement each other, be backup, etc. So, please, if you want to be mentor or second mentor, just let us know. If you want to be second mentor of a project, it would be a good idea to talk with the first mentor so that both agree about that (we don't want problems!!!). Remember ALL mentors and second mentors have to register to our website as soon as possible. To register: http://gsoc2010.esug.org/registration All mentors have to register to the mailing list: http://groups.google.com/group/smalltalk-gsoc-mentors Janko is doing an excellent work with the website as you can see. Here you can see, for example, the list of the current mentors: http://gsoc2010.esug.org/mentors After mentors (when I say mentors are both, included second mentors), students will have to apply. Of course, we will let you know when. Cheers GSoC admin team esug.gsoc.adm2010(a)gmail.com http://gsoc2010.esug.org/

GSoC next steps
by Mariano Martinez Peck March 21, 2010

March 21, 2010

Hi folks. We received several mails asking questions for the next step. So I think it is a good idea to clarify it a bit. Mentors and students, will have to register in Google GSoC website, but first we want them to be registered in our ESUG GSoC website. Why? Several reasons: 1. We are trying to approach this year GSoC on a more organized way, 2. that's why we are building that special Smalltalk GSoc website, 3. to support you, the students and the projects as best as possible. We are developing this registration in our website and it was almost finish. We will call for mentors first. We created a mailing list for all the mentors. If you are mentor, you should be there. If you are not, please contact us. We had already sent an email to mentors mailing list to invite them to register as mentors in our ESUG GSoC website. If we discover bugs during that period, they will be fixed. Once after all mentors have been successfully registered and the registration process is working correctly, then we will invite students to register also. After that, students and mentors will be registered in our website, each of them will have each other's contact information, each will have their own page for the project, etc. Once all of this is done, then mentors and students will register in the Google GSoC webpage. Finally, mentors will vote and choose the projects to be selected. Even more, if there is more than one student for the same project, the mentor will have to choose. Cheers GSoC admin team esug.gsoc.adm2010(a)gmail.com http://gsoc2010.esug.org/

Does vm shipped with Squeak 4.0 support closures? [cross posted]
by Tom.X.Porter＠gmail.com March 20, 2010

March 20, 2010

I know that Pharo (or at least Pharo with seaside) requires a VM with closure support, and the Pharo download page gives access to a vm 4.2.2b1 that supports them. Squeak V4.0 has a vm 4.2.3.b1u, but I am unclear if it was build with support for closures. I just thought I would check on the pharo list and with the mouse folks as well, as I run both on my mac. I guess I might need both VM's. Thanks to both for all the hard work! Tom P.

Re: [Pharo-users] ESUG selected as GSoC 2010 mentoring organization!!!!
by Mariano Martinez Peck March 19, 2010

March 19, 2010

Hi Smalltalkers! Maybe you are not aware of what our selection to this year GSoC really means for the Smalltalk community. And I wasn't aware completely until few hours. Just to give you an example, even such big organizations like Ruby or PHP where not selected. From this viewpoint you can see what we have achieved. Some people said and still says that Smalltalk is old and that it is dead. Ok, we have been selected by the major Informatics and Software company all over the world. The point is that ESUG and the Smalltalk community was selected because of the seriousness mixed with passion of all the application, project and ideas. We have an incredible high quality list of ideas and mentors. We have a unique opportunity to show the rest of the world why we love Smalltalk, why it is much better than other alternatives, etc. So, we invite all of you to make this happens. Thanks to everybody for all the congratulations and nice words!!!

Adding a new reserved word
by Carla F. Griggio March 15, 2010

March 15, 2010

Hi everyone! I want to add a new reserved word to a Pharo image. I tried to find the code that gives special treatment to words like nil, true, false, self, etc. and add my new reserved word, but as though I tried to immitate some things, I was not successful. Â¿What could be the right way to do this? Â¿Can I add a reserved word just adding some code on a Pharo image? Thanks! Carla. PS: The object of doing this is nothing serious, I just want to make a friend laugh with a silly joke :)

A question about application deployment.
by Rayne March 15, 2010

http://code.google.com/p/pharo/wiki/HowToDeployAnApplication Oh that page, it talks about "shrinking" an image: "Reduce the image size by throwing out anything that is not required by your app and which is useless for your customer (unit tests, dev tools)." but it doesn't explain /how/ to do so. How does one "throw out" stuff like unit tests and dev tools? -- View this message in context: http://n4.nabble.com/A-question-about-application-deployment-tp1591431p1591… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Subclassing Float?
by Ch Lamprecht March 6, 2010

March 6, 2010

Hello, I tried to build a subclass of Float without success. More precisely, I did not find out how to build instances from it. Is subclassing Float something I should not do? I am trying to build objects, that represent Audio frequencies. They should behave like Floats but have some additional methods like 'addCent: anOffset' or 'deltaCent: aFrequency' (cent refers to a logarithmic scale used to express frequency relations). Cheers, Chris
