Re: [Pharo-users] Moving/rolling average implementations ?

I note that "self species ofSize: n" is not generally a good idea. Consider ByteArray, ShortIntegerArray, WordArray. Computing rolling means of these is perfectly sensible, but the results will not fit into an array of the same species. I'd stick with Array. The suggestion about subtracting an

Hello Pablo Success! I have rerun one of the troublesome cases, with no problem. I then re-ran the test on the latest 16 messages, collecting all the HTML outputs in an array, which took just over 5 secs total; quicker than I expected. The longest texts, from the most verbose newsletters, run

Re: [Pharo-users] Moving/rolling average implementations ?

Hi Cédrick, for smallCharts, I had to implement the same, but for stock market time series, which are a bit bigger than your example (like creating a 38 day moving average over 5 years). Always copying the values to average is far too slow in this case. My solution is to add up the

[Pharo-users] Moving/rolling average implementations ?

Hi, I wanted to do a moving/rolling average on raw data [1]. I haven’t find code for that (maybe this is done in polymath though). So I ended writing that (I thing this is SMA): SequenceableCollection>>movingAverage: anOrder "Answer the moving or rolling average for anOrder window" |

Re: [Pharo-users] Automation of MS Office from Pharo

Hi!!! This was a great report. I have submitted a fix in the master of Pharo-COM. Basically the problem was to free twice the BSTR in the Variant. It was being free in the access to the value and in the free of the struct. Why it works with other BSTR when they are smaller, I cannot know. I

Re: [Pharo-users] Automation of MS Office from Pharo

Tomaz, that was my understanding from the VBA piece you cited yesterday. So presumably it must be something in Pharo-Com which imposes the limits we have seen. I am OK at the moment, because all this work is just an exploration of possibilities; I can wait until you and Pablo have sorted it

Thanks, Stephane, for the acknowledgement. Peter, as I understand, the limits in COM BSTR data type are defined by the header's length prefix (which is 4 bytes) and software implementatios - for instance, string data type in Visual Basic for Applications is described as "a variable-length
