[racket-users] racket on openwrt devices
What's the current viability of running Racket on a small OpenWRT device? (Anything new, such as due to the recent modularization of the core?) For example of specs of a popular beefy retail home WiFi router that runs OpenWRT well: Processor: Atheros AR7161 rev 2 680MHz (MIPS arch) RAM: 64MiB Flash: 16MiB Getting that up as high as 128MB RAM and 64MB-128MB flash would probably be doable, but fitting Racket on the device within the above specs is strongly preferable, for open source projects. (In the open source application I have in mind, Racket would leave the TCP/IP to OpenWRT and the SoC, and spend most of its time doing a different kind of protocol through a special USB device.)

Nothing that I know of since 2011ish. The smaller core might make it a little easier to assemble a minimal set of collections. > For example of specs of a popular beefy retail home WiFi router that > runs OpenWRT well: > Processor: Atheros AR7161 rev 2 680MHz (MIPS arch) > RAM: 64MiB > Flash: 16MiB Nice. Hmm, that amount of nonvolatile storage will be a challenge. Racket will run in 64MB RAM on a machine of that class, though not well, if my intuitions from 2011 still hold. (Last time I ran Racket on OpenWRT, I was using a Netgear WNDR3700v2.) Tony -- You received this message because you are subscribed to the Google Groups "Racket Users" group.

OK, thanks, Tony. I'll have to give this a try in a week or two. (Last time I ran Racket on OpenWRT, I was using a Netgear WNDR3700v2.) I have a collection of these and similar WNDRs (my home office network is run by two 3700v2 and a 3800, running OpenWRT). For Racket, I'll probably try a 3700v4 or 4300v1 first, since they're 128 RAM and 128 NAND flash, albeit with a different SoC with lower CPU clock rate. I don't want to rely on USB Storage for this project. (Aside: A challenge for an open source project that you want large numbers of people to be able to adopt grassroots-style is to find router model(s) with sufficient specs, and that run OpenWRT well, and yet are still easily available for purchase online and at big-box retailers. Additionally, vendors like Netgear and Linksys often replace the product guts of a model with very different hardware, without changing the model number; so, someone ordering a "WNDR3700" online could be getting any of 4+ different devices, with widely varying specs, and some of which don't run OpenWRT. Some open source projects can also work on Raspberry Pi devices, but sometimes you need the NICs/radios/switch hardware of a cheap router anyway, so you might as well do everything in one appliance box. A soho router is more polished and less expensive than a RasPi with a bunch of daughterboards and USB hubs and devices hanging off of it precariously.)

I should mention also that I couldn't do anything useful with Racket 5.x (as it was at the time) on the WNDR3700v2 without using a swap file on a USB stick (!). Simply not enough RAM or storage for Racket. Tony -- You received this message because you are subscribed to the Google Groups "Racket Users" group.

Simply not enough RAM or storage for Racket. Very good to know. Guess I'll just target the 128MB RAM devices, and not even bother with 64MB. This weekend I'm writing a (hopefully) very-small-footprint HTTP-serving module in pure Racket.
