Uff, what is happening to my fingers today, keep pressing the send button before the mail is ready. Apologies. I am seeing an error in http://seaside.gemstone.com/ss (that is the repository of metacello packages, I believe): Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator, is(a)gemstone.com and inform them of the time the error occurred, and anything you might have done that may have caused the error. More information about this error may be available in the server error log. ________________________________________________________________________ Apache Server at seaside.gemstone.com Port 80 that maybe is the cause of the error in installing metacello. That is Is the server down? CC to the mail indicated in the error page. Cheers -- Miguel CobÃ¡ http://miguel.leugim.com.mx

It just shouldn't be, OrderedCollection doesn't support this.

Doubling size when growing If it would depend on the size of the memory chunk, these values wouldn't be linear: Array streamContents: [ :stream | | size | size := 10. [ size <= 10000000 ] whileTrue: [ | coll | coll := OrderedCollection new. Smalltalk garbageCollect. stream nextPut: size -> [ 1 to: size do: [ :i | coll add: i ] ] timeToRun. size := size * 10 ] ] "==> {10->0 . 100->0 . 1000->0 . 10000->2 . 100000->22 . 1000000->282 . 10000000->2490}" > is also not an acceptable strategy when getting close to > total ram capacity. If the growth is not exponentional, the O(1) and O(n) runtime will quickly become O(n) and O(n^2). If a single data structure's size is getting close to the total ram capacity you have three options: - buy more ram (this is really cheap nowadays) - use another data struture/another way to represent your data - use another language which is closer to your hardware But this is really an edge case. In the last five years I only had two such cases. I took the hard way and rewrote the programs in C++. It was pretty easy because I just had to translate the Smalltalk code to C++.

[Pharo-project] Problems with ConfigurationOfMetacello in PharoCore 10514

by Miguel Enrique CobÃ¡ Martinez

Sorry, I pressed the button to early... full mail follows: Take a PharoCore 10508, update it with update stream to 10514. open a workspace and evaluate: Gofer it squeaksource: 'MetacelloRepository'; project: 'ConfigurationOfRFB'; load. Then ConfigurationOfRFB project latestVersion load It shows an error: Unable to resolve ConfigurationOfMetacello in method GoferPackageReference>>resolverWith: Installed packages: Gofer-Core-MarkusDenker.117 Gofer-Tests-MarkusDenker.116 ConfigurationOfRFB-tbn.4 Same happens with: Gofer it squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfMagma'; load. ((Smalltalk at: #ConfigurationOfMagma) project version: '1.0r43') load: 'Tester' If I manually install Metacello (not bootstraped from gofer): Gofer it squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfMetacello'; load. I get: ConfigurationOfMetacello-DaleHenrichs.194. If I run now the ConfigurationOfRFB project latestVersion load I get: Error: Unable to resolve Metacello-Core-DaleHenrichs.348 If I run ConfigurationOfMetacello loadLatestVersion I also get the error: Error: Unable to resolve Metacello-Core-DaleHenrichs.348 So, what should we do? I am seeing that ConfigurationOfMetacello>>version10beta24: has blessing #beta and uses package Metacello-Core-Dalehenrichs.349 but ConfigurationOfMetacello>>version10beta23: has blessing #beta and uses package Metacello-Core-Dalehenrichs.348 so, loadLatestVersion is not getting laste 1.0beta24 version but 1.0beta23 version for metacello Can you please check?

Hi list, the purpose of PluggableSet and KeyedSet is the same: they're both sets where the equivalence relation is overwritten by a block. One of the two should be removed. What do you think? Cheers, Niko -- http://scg.unibe.ch/staff/Schwarz twitter.com/nes1983 Tel: +41 076 235 8683
