The PharoForTheEnterprise book has a chapter on Nativeboost. You can find the book here in pdf format https://ci.inria.fr/pharo-contribution/job/PharoForTheEnterprise/lastSucces… also you can click on the folder to download only the Nativeboost chapter, but I advice to download the whole book since it has tons of useful info.

Accessing DLLs in Smalltalk/V

by Bob Williams

I found an old Smalltalk/V imagine from 2000 and tracked down how I was able add calls to Windows DLLs and to add my own. It was in the class DynamicLinkLibrary and its subclasses, e. g., a call to the GDIDLL to draw a Bezier spline (which I believe I added) was: bezierTo: hDC lpPoints: anLPPOINT count: anInt <api: PolyBezierTo ulong struct ulong boolean> ^self invalidArgument I added by own DLL to do matrix transformations that was written in ASSEMBLER to optimized the floating point processor pipelining (a start operation every cycle while it took 3 cycles to complete) and it performed about 15% better. I have not found anything similar in Pharo, but it must if external libraries are used. NativeBoost seems to come close, but I cannot find any documentation. Can someone point me to some documentation, code, anything? It is greatly appreciated. bw

Thank you guys, I'll give Postmark a try. I already defined the DKIM/SPF records in the DNS Zone. It's the first time I see such thing in a DNS table, I hope this works well... Regards! Esteban A.

I used postmark as well some time ago, and it worked like a charm. In the mean time I switched to using the builtin smtp client, because itâs a very low amount of mails and I could use the departmentâs smtp server :-) On May 29, 2014, at 9:17 AM, Marcus Denker <marcus.denker(a)inria.fr> wrote: > > On 29 May 2014, at 15:10, Esteban A.

So you would need to use then the outbound SMTP server of DigitalOcean, if they have one. Sending email is harder than you think these daysâ¦ Marcus

Sending transactional emails from Pharo

by Esteban A. Maringolo

What is the simplest way we have in Pharo to send emails? We're going to send a bunch of "no-reply@mydomain" style mails confirming transactions and similars. ~3000 mails. Anybody already doing this? Regards. Esteban A. Maringolo ps: This will be running in a DigitalOcean droplet, so I could install an email server, but I don't think it is the simplest solution :)
