Ok, strangely, when I go to that page in Firefox it doesn't show that error. Tried to go with Chrome in incognito (so as to get rid of plug ins) and it still fails. Gonna try from within Pharo and if it fails I'll post again. Below are screenshots on how it fails or succeeds on each browser.

[ANN] Pharo Chip Designer

by Pavel Krivanek

Hi, I have created a little program based on an old educational game by Zachtronics (KOHCTPYKTOP: Engineer of the People[1]) named Pharo Chip Designer. It is an inaccurate and highly simplified tool for the design of silicon chip layouts. Unlike common tools for logic circuits designs, in Pharo Chip Designer, you need to face the real-life problems like propagation delays or limited amount of layers and available substrate area. https://github.com/pavel-krivanek/PharoChipDesigner <https://github.com/pavel-krivanek/PharoChipDesigner/blob/master/README.md> It contains levels from the original game, but you can play with your custom designs on larger surfaces. And of course, use all the Pharo power to control the I/O signals. The Pharo Chip Designer required Pharo 8.0 and Spec2.

Re: [Pharo-users] Destructive copy in #replaceFrom:to:with:startingAt:

by Richard O'Keefe

The ANSI Smalltalk standard is characteristically vague here. Both the memmove and memcpy readings are consistent with it. The standard is characteristically buggy here too: the two lines I've flagged with ** disagree. I take the second one to be correct. 5.7.12.5 Message: replaceFrom: start to: stop with: replacementElements startingAt: replacementStart Synopsis Replace the elements of the receiver between positions start and stop inclusive with the elements of replacementElements, in their original order, starting at position replacementStart. Answer the receiver. Definition: "for" <sequencedCollection> The element at position replacementStart in replacementElements is stored in the receiver at position start; the element at replacementStart + 1 is stored at position start + 1; etc. Any previously stored elements at these positions in the receiver are replaced. **If the size of replacementElements is not equal to (replacementStart+stop-start), the result of sending this message is unspecified. Errors, If start < 1 or start > the receiverâs size. If stop < 1 or stop > the receiverâs size. If replacementStart < 1 or replacementStart > replacementElements size. **If replacementElements size - replacementStart + 1 < stop - start + 1. For what it's worth, GNU Smalltalk answers #(1 2 3 1 2 3 4 8), as does my Smalltalk library. So does VisualWorks. It's a primitive in VW, so I can't see what the code does, but the comment is tolerably clear: "No range checks are performed, but overlapping replacements are handled correctly." VisualAge Smalltalk gives the memmove answer too. The Dolphin sources say "Overlapping moves are correctly handled." ST/X makes a special check for the receiver and source being the same object and conditionally calls memmove to do the transfer. Strongtalk doesn't check for receiver == source but does check for repStart < start, so also belongs to the memmove group. So Squeak/Pharo stand out as different here. susie-0.3 and syx-0.1.7 and panda all do the memcpy() thing too, but they don't count as finished.

Also did you use the URL of the page your repo is on? Seems like maybe you did from the image. You shouldn't. You should use the Monticello Repository specification shown on the repo page when you hover over Monticello Repository in the Getting The Code section of the project page on ss3. e.g. MCHttpRepository location: 'http://ss3.gemtalksystems.com/ss/GTDImplementation' user: '' password: '' Paul DeBruicker wrote > what is the repo you're having trouble reading? > > > Sergio Fedi wrote >> Hello, >> >> I'm coming back after a few years (Pharo 5.0) and tried to take a look >> and >> download some projects I have on ss3. >> >> I'm using a Pharo 7.0 image. >> >> Going to the ss3 site I find that I can't access my projects, a "Reading >> a >> number failed: a digit between 0 and 9 expected" error shows in the page. >> >> Trying to view them from Monticello, after adding the appropriate >> repository it shows weird characters for the name and versions and it is >> unable to load them. >> >> [image: image.png] >> >> What am I missing/doing wrong? >> >> Thanks! >> >> >> image.png (182K) >> <http://forum.world.st/attachment/5102137/0/image.png> > > > > > > -- > Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
