[Pharo-project] Switching windows using CMD+right/left
by Benjamin Sept. 23, 2011

Sept. 23, 2011

He guys, I really would like to know if someone is using the shortcut cmd+right/left to switch between windows into Pharo. Because right now on Mac, this shortcut is used to jump to the begin/end of the line, when fn+right/left jump to the begin/end of the file. It means that per day, I lost 15 minutes (and my nerves ^^) because in eclipse I just jump at the end of the file instead the end of the line ( and then I have to scroll back... frustrating), and when I code in pharo, I use cmd, and then it swap the window. And the worst part is that cmd+right followed by cmd+left do NOT bring you back to the original window, so I am lost and it frustrates me a lot ^^ So I would like to propose to change the shortcut binding to be a bit consistent between pharo and mac (could windows/linux user tell me how it works on those platforms ?), and use ctrl+tab to switch between inner windows (like in a web browser or cmd+` like in Mac OSX Please tell me your experience about this, cause http://www.dailymotion.com/video/x4m18_queen-i-m-going-slightly-mad_news ;) Ben

[Pharo-project] Two objects with same hash

If you are on Windows you can use Microsofts GUID. I wrapped them in http://www.squeaksource.com/COM.html as class COMGUID. They are unique in time and location so you need no additional date. If I remember correctly the UUID plugin for Windows used them directly as the underlying generation algorithm ... I also expected UUIDs (for instance if generated on Mac or Linux) as unique in time and location so it should not be possible to generate the same value at the same time on two different computers.

This means that a hash is *not* at all a UUID, and all hashing data structures need to be optimized for the case of hash collision, as it will happen a lot.

Sept. 23, 2011

Hi, Squeaksource is down at this moment. While wating, I send this question. Can Metacello work locally and remotely to squeaksource or other 3rd server? Stack up some versions locally and later sync them with squeaksource?

[Pharo-project] Two objects with same hash
by Denis Kudriashov Sept. 23, 2011

Sept. 23, 2011

Hello, I use hash message to generate unique object id. (unique between current memory objects). And I catch situation when two objects has same hash value. Objects has been created in loop almost at same time. So my question - is it really possible? Can it be bug in my current VM which I used? (it is cog but very old) What you can recomment me for unique object id? Best regards, Denis
