September 2016 - Pharo-users

Re: [Pharo-users] [ANN] Territorial Re-Licensing

by Dimitris Chloupis

well he did apologize And these things do happen in all communities, I cannot begin to describe the poison I have received in the #common-lisp irc channel. One time also in their mailing list , some old member got annoyed for small reason with a begineer and he gave him code to delete his hard drive, fortunately other members replied immediately after warning the beginner not to execute the code. License wise MIT/BSD are by far the top most popular license , they got so popular that FSF was forced to release LGPL to compete with them but at the same time not upsetting too much their GPL supporters. So as you can see Pharo is no exception, its actually the rule. Also other licenses are very close to MIT/BSD making MIT almost a monopoly on open source software. Don't believe me ? Here are the top trending github repos that contain a code license ( creative commons applies not to code but mainly to assets, music, sound, text, graphics, fonts, etc) https://github.com/facebook/zstd https://github.com/tensorflow/tensorflow https://github.com/vuejs/vue https://github.com/camwiegert/in-view https://github.com/nasa/openmct https://github.com/baidu/Paddle https://github.com/facebookresearch/fastText https://github.com/david-gpu/srez https://github.com/quilljs/quill https://github.com/shekhargulati/52-technologies-in-2016 Mostly they are MIT , others are MIT like licenses like Apache and BSD, only one is a custom made one still similar to MIT. None GPL not even LGPL. https://github.com/trending?since=monthly Actually you can continued down the list and I am sure will take you even more time to find a GPL or even LGPL licensed open source project.

I am consuming the Twitter API and it don't get so much time like this to get a response. Besides, while those profiles were made at a Windows 10 local machine, the same code on a Pharo 5 (get.pharo.org) deployed on a linux deploy on Digital Ocean takes ~6 seconds, which means that a lot less time is spent on I/O. Isn't that Strange? I will try to spin up a local linux machine with both a headfull and headless Pharo to see if this time changes. > > Is there a way to profile a remote image?

Perhaps there is a way to optimize this, but what catch my attention was the huge amount of time spent on the idleProcess. Been that I/O wait, it shouldn't be like this. Why not ? You are doing (lot's of) network I/O. It is normal that your image code has to wait from time to time for data to come in from the network. By definition that is slow (in CPU terms). The Digital Ocean instance is probably faster in that respect. Also, having the IDE UI with lot's of tools open might influence things. Best do some more experiments. But benchmarking is very tricky. > Thanks, > Vitor > > On Thu, Sep 8, 2016 at 4:42 AM, ClÃ©ment Bera <bera.clement(a)gmail.com> wrote: > > > On Thu, Sep 8, 2016 at 3:44 AM, Vitor Medina Cruz <vitormcruz(a)gmail.com> wrote: > Hello, > > While profiling some I/O code that takes ~20 seconds to execute under my local image, the report says that about ~13 seconds is waste on OtherProcesses -> ProcessorScheduler class>>idleProcess. I could not understand what this idleProcess do by looking at the code. First I thought this could be time waiting the I/O operation to terminate, but that don't make much sense because I have the same code on a Digital Ocean Doplet and it takes ~6 seconds to execute. > > Can someone help me understand what does this time on idleProcess means? > > The VM is not event-driven. Hence when all the processes are suspended or terminated, the VM falls back to the idle process. The idle process waits for 1ms, checks if any event has occurred and/or if a process can restart, and if not waits for 1 more ms to check again. That's kind of dumb but it works and we need both time and funds to make the VM event-driven (in the latter case the VM restarts directly when an event happens, instead of checking at the next ms). > > Basically the idle process profiled time is the time where Pharo has nothing to do because all processes are terminated or suspended.

Re: [Pharo-users] Profiling

by Vitor Medina Cruz

Thanks for the answers! If this is time spent on I/O it is really strange. I am consuming the Twitter API and it don't get so much time like this to get a response. Besides, while those profiles were made at a Windows 10 local machine, the same code on a Pharo 5 (get.pharo.org) deployed on a linux deploy on Digital Ocean takes ~6 seconds, which means that a lot less time is spent on I/O. Isn't that Strange? I will try to spin up a local linux machine with both a headfull and headless Pharo to see if this time changes. Is there a way to profile a remote image? I would like to see what is happening in the Digital Ocean deploy. Maybe put the headless Pharo there in profiling mode? Ben: this is a heavy json parser procedure, I would expect to NeoJson to take some time. Perhaps there is a way to optimize this, but what catch my attention was the huge amount of time spent on the idleProcess. Been that I/O wait, it shouldn't be like this.

Hi Tudor, I recognize the impedance with mail as an expression medium and most of the time it was like you said, except when Stef addressed to me with "It is amazing how you like talking" (is this some kind of invitation to "just shut up!"? Is that a "remainder" I have not written enough code to have a valid voice here?). For me, if someone has no the time for a detailed response, going with: "GPL is a plague", "You can argue I don't care" or "Pharo is MIT. Period.", or fighting the person instead of fighting the argument, makes more harm that good. No clarification, because lack of energy or time, seems better that these alternative "clarifications". Not all the people is trying to start a holy war anytime makes a suggestion or shows a different position. Sometimes we're just trying to contribute and understand, even when we come from different places, interests and life paths. Thanks for pointing the LGPL issue (so, 3 BSD, MIT, public domain are a good fit). At least I made my contribution by pointing the Etoile place where there is a *rationale* behind a license choosing that makes this licensing issues clearer for newcomers. Energy is low today, but putting things in perspective, most of the time community is welcoming, even if particular interactions among people are not.

Hi Offray, I am sorry you feel down. The wording of Stef did appear strong. However, please keep in mind that email is a terrible medium for expressing and transmitting feelings. I would kindly ask you to reconsider the emails and focus on the content and you will see that the wording was not about the external project but about the decisions that relate to the licensing of Pharo itself. As Esteban and I clarified, Pharo is MIT and will remain MIT. There is a long history of why this is so and a huge amount of effort to make it clean MIT. To keep it clean we have to be aware of the implications of another kind of a license, and our clarifications were about how we, those that work on the main Pharo code, will not touch a GPL code and that this might have a counter productive impact on the originator of the code in question (due to a lack of engagement from other people). Please also keep in mind that we do not want to prevent people from choosing their own licenses. The decision of the license belongs exclusively to the creators of the code. We are only looking for the interests of the core of Pharo to make sure that you will continue to have whatever options you choose on top of it. And you will always be free to choose what you want for your projects. Just a note about other licenses you mentioned: in the context of Pharo, LGPL has the same effect as GPL given that there is no concept of binary reusability in our system. So, for that purpose, we also do not touch LGPL. A final point: when someone says that "we decided something a long time agoâ, it is easy to take it as a âthis is it, just take itâ, but that would be a bit unfair. A more fair alternative is to understand that time is scarce and sometimes we just do not have the available energy to provide all clarifications on demand right at that point. Please letâs focus on building things together, even if there are misunderstandings or seaming differences in opinion. We need everyoneâs energy.

Nice to know something good came out after taking all the heat. In my case I learn about licensing with the reasons behind and not "just take it!"...

Hence when all the processes are suspended or terminated, the VM falls back to the idle process. The idle process waits for 1ms, checks if any event has occurred and/or if a process can restart, and if not waits for 1 more ms to check again. That's kind of dumb but it works and we need both time and funds to make the VM event-driven (in the latter case the VM restarts directly when an event happens, instead of checking at the next ms). Basically the idle process profiled time is the time where Pharo has nothing to do because all processes are terminated or suspended. You can say that it is the time spent in I/O operations + the time before Pharo notices the I/O operation is terminated, which can be up to 1ms. > > The full report is: > > - 18407 tallies, 18605

Re: [Pharo-users] Spur problem?

Usman I do not think that Synectique should deploy Pharo 50 products before any real experiences have been done and this is good that you are doing them because Synectique as Moos as some special memory setup.

Re: [Pharo-users] SpecBooklet: Strange behavior of ProtocolBrowser

by stepharo

Johan let me know if there is anything that I should do. Stef Le 8/9/16 Ã 01:11, Johan Fabry a Ã©crit : > Excellent, you found a bug in my code! > > What happens is that when one item is selected in a list, in the other list the currently selected item is de-selected. This causes *both* blocks (whenAPIChanged: and whenEventChanged:) to be executed, and depending on what order they are executed the behavior is different. (A classical concurrent programming problem.) This order apparently changes depending on how many windows you have open, et cetera, I guess because of how the announcement system is implemented. > > So, yes the easiest solution is to remove both ifNil: [â¦] lines. The UI will not work as cleanly, but it is a quick fix.
