Settings: where are they stored?
by stepharo Oct. 21, 2015

Oct. 21, 2015

Hi guys I took latest image set up some fonts. Then pressed saved. "Information Settings has been stored on the disk." would be good to know where. I have no clue. Then I tried load I got: no idea what it is. Information Cannot update #Nautilus#emptyCommentWarning. Exception: MessageNotUnderstood: Nautilus class>>emptyCommentWarning: I want to set automatically and programmatically settings and I thought that I could use Ston saved settings but I looks like a not so good idea.

hey Ron, It was actually the Pharo Cryptography team I was thinking of. Perhaps we can get the same package to work in both squeak and Pharo, with use of installable entropy sources or the like. In order to get SqueakElib running in Pharo I need crypto and we may as well do it right.

Stream instead of string concatenation
by Jan Vrany Oct. 20, 2015

Oct. 20, 2015

Hi there,Â it's a little less than a year ago the above issue has been raisedÂ by Uko [1]. I run some benchmarks (a little less than year ago :-) With the integration of QA this issue may deserve some attention again. Besides, Uko asked for a feedback.Â The rule seems to be wrong - it barks on code which is (seems to be)Â perfectly fine performance-wise, For example:Â shutUp Class allInstances do:[:cls | Transcript show: 'barking at' , cls name ] See *some* of the benchmark results:Â http://bit.ly/1GnZ3K0 My interpretation of the result is the following: For small number of concatenations, i.e., up to 5, with no accumulator and with reasonably small strings, i.e., shorter than 50 bytes,Â it's actually faster to use string concatenation.Â Using streams is slower, unless one preallocates stream backingÂ string to exactly the size needed. In that case, it's roughly the same as string concatenation using #, You may find full benchmark data at:Â https://swing.fit.cvut.cz/calipel/archive/943.json https://swing.fit.cvut.cz/calipel/archive/944.json Benchmark source:Â https://bitbucket.org/janvrany/jv-calipel/src/tip/s/benchmarks/micro/Be nchmarkMicroStringConcat.st?fileviewer=file-view-default https://bitbucket.org/janvrany/jv-calipel/src/tip/s/benchmarks/micro/Be nchmarkMicroStringConcatN.st?fileviewer=file-view-default Indeed, I could have messed up things - we all know about lies, damn lies and benchmarks.

VM background reading "porting squeak"

Oct. 20, 2015

Just sharing that I found the following chapter from Mark Guzdial's "Squeak: Open Personal Computing and Multimedia" an interesting background read on the VM. Cross posting since some others not on [vm-dev] might similarly find it interesting. http://sdmeta.gforge.inria.fr/FreeBooks/CollectiveNBlueBook/porting-subfina… cheers -ben
