S Krish wrote > Pharo Morphic View and Pharo Tabbed Pane IDE. Thanks for the link! I read the blog post and linked document (the second link is a 404). A few comments/questions: - How does Pharo Morphic View differ from / enhance what's already available with Spec? They seem to provide a lot of similar functionality... - Spec conflicts: I was going to load it, but then noticed that it redefines some Spec classes (e.g. CheckboxModel, RadioButtonGroup). Since Spec is becoming more integrated with the system (tools are converting to spec-based), I don't know what the ramifications of that would be and I would rename those classes. - The inbox is probably not a good place to store these, unless you're proposing that they be included, in which case please open an issue Cheers, Sean -- View this message in context: http://forum.world.st/Morphic-View-UI-and-Pharo-Tabbed-Pane-IDE-on-Pharo-2-… Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

[Pharo-project] [ANN] ZTimestamp[Precise]SNTPClient

by Sven Van Caekenberghe

Hi, It is often important, especially for server applications, to know if the current local clock is still OK. The standard way for doing that is part of NTP (http://en.wikipedia.org/wiki/Network_Time_Protocol) I implemented two SNTP clients (one with ZTimestamp's second precision and another one using DateAndTime's nanosecond precision) that can be used to check the difference between the local clock and the clock of any NTP server. ZTimestampPreciseSNTPClient new clockDifference. -0:00:00:00.005786228 This reports that the difference between the local and remote clocks is in the order of 5ms, as computed in one specific way. Other queries are related to the Clock synchronisation algorithm. ZTimestampPreciseSNTPClient new localClockOffset. 0:00:00:00.065466869 ZTimestampPreciseSNTPClient new roundtripDelay. 0:00:00:00.037001908 In practice the following would be a useful practical check. ZTimestampPreciseSNTPClient new enforceClockDifference: 2 seconds ifFail: [ :delta | self warn: ('Clock difference {1} > 2s' format: { delta }) ]; close. As NTP uses UDP datagrams, this is a nice example for that as well. The code can be found in the following repository: http://mc.stfx.eu/Neo It is probably easiest to load the ZTimestamp configuration using the Configuration Browser and then load the bleeding edge version (it is not in de released version). The code is self-contained and loads cleanly. ConfigurationOfZTimestamp project bleedingEdge load. The client contacts a server from pool.ntp.org. The code does only deal with a limited aspect of NTP, which is rather complex and wonderful subject matter (http://tools.ietf.org/html/rfc2030) My goal was to get a dependable result, not be be super accurate.

Re: [Pharo-project] fast #becomeForward: crashes without PharoV10.sources

by Igor Stasenko

we should reafctor the code for changing the method's trailer (source pointer) to avoid using #become: at all. this won't deal with VM bug per se, but at least prevent it from triggering.

[Pharo-project] Morphic View UI and Pharo Tabbed Pane IDE on Pharo 2.0

by S Krish

HI, Just started to use Pharo 2.0 and find it nice overall. The package loading time, is something I need to recheck, profile and see, but feel there is a lag. Few other minor issues, nothing major so far. Smooth integration of the work I had done in 1.4: Pharo Morphic View and Pharo Tabbed Pane IDE. Try it out and let me know: http://skrishnamachari.wordpress.com/2013/02/26/pharo-2-0-morphic-view-and-… Will come back on the Pharo Tablet like interface that I have talked of earlier as also the integrated Brett Taylor like dynamic UI construction...

[Pharo-project] ImageDirectory DirectoryDoesNotExist

by Sean P. DeNigris

Several times in #20567, I've been working for a while, and then all of a sudden: - I lose my temp names - Clicking on Packages in Nautilis -> ImageDirectory DirectoryDoesNotExist - Image save -> Error: Failed to write image file (disk full?) I wasn't doing anything unique at these times that I can point to... Is anyone else experiencing this?
