methods for license conversion

methods for license conversion Hi Pavel, I know you are putting in good effort and trying hard to do what is needed. We are a resource thin community and what you are proposing to accomplish would require a lot of work just to get to first base. http://comtalk.net/public/pub/KernelImage/20070704/info.txt shows: 960 unimplemented calls no morphic DOA and useless as it stands, imho. I have tracked down and fixed some unimplemented calls. Each one takes the resources of an evening at least. Where will we find the resources to fix 960 of them? Meanwhile squeakland is offering the squeak plugin under the apache license. What is stopping us from doing the same or at least starting from there? How did Squeakland and VPRI manage their license change? Why can't we hop on their efforts? Have I missed something in this analysis?

Using a keyboard with Squeak on the Nokia 770/N800
by Aaron Reichow 04 Jul '07

04 Jul '07

Hey all, Just a little note- I've had some luck using my bluetooth Keyboard with my Nokia N800 and Squeak. I mention this specifically because with a keyboard, the Nokia N800/770 makes a cool little laptop- I'm building a simple laptopish case out of cardboard and because teh Maemo platform the Nokias run on is a bit funky with regards to input- e.g. unlike on CE, you don't have access to the OS-level software keyboard, etc to input into Squeak, and as such we've relied on Genie or soft-keyboards inside Squeak to input text. Since the KB doesn't support the HID profile, you have to use a driver. Driver: http://fanoush.wz.cz/maemo/ Keyboard I'm using: http://www.freedominput.com/site/index.php? option=com_content&task=view&id=12&Itemid=28 The keyboard I'm using, but which uses the standard HID profile, which is a better way of doing things in many ways: http://freedominput.com/site/index.php? option=com_content&task=view&id=15&Itemid=34 What is great about the Freedom BT keyboards is that unlike every other foldable I've seen they have a number row. Makes a huge difference if you're coding- on the IrDA keyboard I had for the Zaurus I had to press two keymodifiers to get a lot of punctuation chars like [, etc. The keyboard has been working well, but no Alt- modifiers present or interpreted by the driver; Ctrl- and Shift- clicking work fine, and there is a key which seems to be mapped to escape which is handy for bringing up context menus. Not sure if regular HID-compliant keyboards (which just work on the Nokias) work in Squeak, but I don't see why they wouldn't. Just a little info for those wanting to make a novy-HandheldPC-cum- Dynabook out of a Nokia 770/N800. :) Regards, Aaron

>If you want to send one message and have everyone hear it then you have to use UDP, which is connectionless. Can you elaborate on this? How could this be done? Any sample code or doc on this? Thanks in advance.

SmalltalkImage current
by Norbert Hartl 04 Jul '07

04 Jul '07

Hi, I read in a posting from Andreas that there are problems with the renaming from Smalltalkk to SmalltalkImage current. I discovered problems with it several times myself. That remembers me that I wanted to ask what were the reason to change it? It breaks a lot of code and reading this list it appears to me that nobody likes it :) So how came it has been renamed? Btw. how much smalltalk images I'm able to run. new is disabled. I don't get it. Any hint is appreciated. Norbert

The land of the Mice, a bedtime story
by goran＠krampe.se 04 Jul '07

04 Jul '07

Let me tell you a story... I was around... when King Dan ruled the Land of the Mice, his court the "SqC" was strong and the stream was flowing smoothly. It was a glorious and joyous time and I were there to see sir PWS, sir Comanche and princess Swiki being born as children of Socket. The wizard Morphic was still young and agile at that time... Things were well, but not everyone were happy in the Land of the Mice - the population grew quickly and only the fortunate ones to enter the castle Image could have their fields fully prosper and not wither and die in the harsh outbacks of the Internet. During this era the (oh, so lonely) renegades of Stable Squeak rose and fell. A noteworthy effort and something to learn from, they were probably the first to wander outside of the monarchy trying to create something on their own. But they tried to do everything on their own and soon perished under lack of time. Together we are strong but in few numbers we do not weigh that much. I was around... at the Great Gathering (OOPSLA) when King Dan and his court withdrew from power and left the land in the hands of the Guides, a humble group that tried to guide, but did not manage to lead and capture the hearts and dedication of mice as the formidable King had been able to do before them. Only a few brave souls during this era kept the state apparatus working - wanderer Marcus and blacksmith Doug comes to mind, also being guides at the time and doing a fearful amount of work to keep our stream facilities working. Though clearly undecisive, this era was still to be remembered as a relatively good time - the time when a lot of new useful structures were erected by brave dedicated citizens, like for example monastery Monticello, the castle of SqueakSource and the holy library of SqueakMap. And the new popular plaza - SqP - where citizens could post their writings on walls for all to see. All in all, great accomplishments - but still, an undecisive era becoming more and more vague in direction and loosing momentum. I was around... to see the revolution that begun the short third era - the one year of benevolent dictatorship. A small group took a firmer charge of the land, by force - with the aim to create a new constitution. This was not looked upon as something good by all citizens. It was also the rebirth of Squeak.org and the acquisition of the electronical citadell - box2 - where all holy scrolls and resources were kept. During this year they started a process towards a democracy, strongly believing that this was the only way forward for the land of the mice - a stronger rule enabled by the display of trust from the citizens. This group had many names but promised *one* thing, and that was to step down after exactly one year. And when one year had passed this was also fulfilled and they were replaced with a group elected directly by the people! The land of the mice entered the fourth era - the era of The Board, a Democracy. During the second, third and fourth era, groups of fellow citizens moved off in different directions and created new communities throughout the land like the mysterious Croquet island, the infectious brotherhood of Seaside, the true temple of the Spoon, the state bureau of Mantis and lately even a modest but popular food court called SqueakDev, just to mention a few. The land of the mice is fertile with more citicens than ever, even though spread out in various parts of the continent. We are now in the second year of the fourth era. Are the citizens happy? Or is there confusion and paralysis spreading slowly across the land? Is the bureacracy and constitution working as we hoped or is it slowly eroding the hearts and souls of mice? ...is the magic gone? And if this is so.... what can we learn from history to do something about it? Can our land be yet again changed through a revolution? Would it be wise? Or is it just a lack of strong builders creating new castles and houses of wonder? Can the land sustain more than one castle? ...to change the land of mice... or to raise the sails and find new land across the sea? And with those words my friends, it is time for you to sleep on it. Good night. /Göran

[Help] the meaning of #hex is now quite muddled.
by Jerome Peace 04 Jul '07

04 Jul '07

[Help] the meaning of #hex is now quite muddled. See http://bugs.squeak.org/view.php?id=6441 0006441: [BUG] SmallInteger hex not understood In 3.8 Integer>>hex was deprecated but not the other occurances of the message. In 3.9 Integer>>hex was removed. But still retained callers. So DNU errors occured (see report). johnpf who reported the bug has cared enough to implement several fixes one of which has gotten into 3.10. He has replied to my requests to write tests for the issue. The problem is the answer his fix gives is not equivalent to the answer given by the routine in 3.8 (again see the report) This has lead to several questions that need answers ( see report ) but he is too new to know the answers and so am I. There needs to be a consistent meaning for the message. And we need more knowledgable souls to guide us to it. Yours in curiosity and service, -Jerome Peace ____________________________________________________________________________________ Get the Yahoo! toolbar and be alerted to new email wherever you're surfing. http://new.toolbar.yahoo.com/toolbar/features/mail/index.php

Enter a project and *then* ...
by Jim Rosenberg 04 Jul '07

04 Jul '07

I have some projects where I need to navigate among them via buttons. When I apply the enter method to a project from a mouseUp: method from an object in a different project, it works. But code in that method following targetProject enter is just not executed. It's as though entering a project completely "reboots" code execution from inside that project. How can I enter a project and then execute code from inside that project, where the code is invoked from the "source" project? This is all very puzzling, and seems like magic. Here's an example of something that doesn't work. Bring up an explorer on an object with an instance variable containing a project. Highlight the project, and then doIt the following code: self enter. PopUpMenu inform: 'Hoot' If "self" refers to the same project, the Hoot message appears. But if "self" refers to a different project, the project is entered but the 'Hoot' doesn't happen. How do I do "project-spanning" code? -Thanks, Jim

Hi, Thank you very much for your all answers. As I said in my previous mail, I cannot assume that I can use multicast/broadcast support because there's some routers which do not support these features. It seems that my original idea - though TCP part could be replaced by UDP for efficiency - might be my last choice. My current idea is that all clients are connected to the server and between clients and server, single byte data (kind of ping) is exchanged periodically and if the clients received some new data is received to the server, then client fetched the data and display. Any client can post new data to the server through another transport(maybe TCP for this case?). I think this kind of application will be helpful for broadcasting messages to the people(like flashmob :-) Thank you again. ----- Original Message ----- From: Joshua Gargus <schwa(a)fastmail.us> To: johnmci(a)smalltalkconsulting.com, The general-purpose Squeak developers list <squeak-dev(a)lists.squeakfoundation.org> Sent: 07-07-04 10:13:17 Subject: Re: Re: [OT, Q] Architecture for Message Broadcasting Various versions of Croquet have used UDP broadcast for LAN discovery. I haven't heard of anyone doing IP multicast in Squeak; as others have noted, support for IP multicast is not widespread on the internet at large. We might be wandering away from solving S.J.Chun's real problem. Depending on what he (she?) is trying to accomplish, his original approach may be quite viable. At a very high level of abstraction, a Croquet router could be said to work in that way.
