Re: [racket-users] Re: Boot To Racket

I've been following this discussion with keen interest. Although my Liitin.org project is far from minimal in size (viable sized by design), it does have some common objectives. Racket is used as "the native language" that is meant to be able to control all areas of the cloud-based, native

Re: [racket-users] Order of argument conventions, or ... conventions of argument ordering

Not to give an excuse to design the argument order poorly... it would be great if DrRacket could display named place-holders for each argument dynamically. Then you wouldn't need to guess or try to remember illogical set of parameter orders. The argument name could be taken dynamically from the

Re: [racket-users] Custodian problems/ IoT service

The previous code was messy all over the place. This one seems to work, although I'm not sure whether it can keep the services securely sandboxed as intented and won't run out of memory at some point. Revised code: - #lang racket ; tested in Linux (define target-mode #f); #f/

[racket-users] Custodian problems/ IoT service

Hi all, I want to make a custodian-protected, remotely-controlled service switcher but there's something wrong with my code. The behaviour isn't reliable and it leaves traces behind filling the memory eventually. I've included the code below. TBH, I may have a less optimal approach to it

Re: [racket-users] Anybody done some "Internet of Things" stuff with Racket?

I'm currently experimenting with Tony's racket/stomp package that you might want to check out, too. The idea is to provide more generic messaging services for liitin.org project, not just IoT but also between people, software services, cloud computing and such. Initial target is an

[racket-users] Time-limited evaluation

Hi all, I'm probably doing something wrong here, but for some reason "custodian-shutdown-all" doesn't always interrupt the execution as the last test case below shows. It continues execution until finished. Any ideas how to get this working? br, jukka --- #lang racket/load (require

Re: [racket-users] Time-limited evaluation

Hehe, I think I need a faster computer, because that was the intention. Anyhow, I'm glad it's working. I think what happened was that initially I didn't have it right and lowered the number to make debugging faster. Then tested with another function and got confused. Thank you Matthew for

[racket-users] Racket education & activities in greater Helsinki area?

Hi all racketeers in Helsinki or nearby, I wonder if there are any Racket courses or other Racket-related activities available in Helsinki or the surrounding areas? I'm mainly interested in open university type-of CS lessons, or Internet of Things kind-of hobby activities, but anything

[racket-users] Eval namespace revisited ...again

Hi all, I'm working on a generic solution to distributed computing/ IoT/ M2M/ scheduled task handling etc. basing on messaging. The emphasis is on usability so it is essential to allow running functions identically despite of where they are run. The obvious thing to expect is that when sending an
