Re: [racket-users] self contained zip file install?
HI, If you do the build like I said it does not need to live in Program Files. It can live in your user directory, for example.

Re: [racket-users] self contained zip file install?
HI, So before I would download the minimal windows tar file to a linux system, untar it, and then zip it back up. Then that could be copied to the corporate windows system and unzipped. And that give a minimal Racket. The part that has stopped working is I used to be able to, from cmd, run: raco pkg install -i racket-lib raco pkg install --deps search-auto -i main-distribution And I would have a fully working Racket. So this required cmd.exe to be run. Can you run Powershell? That can be convinced to do those commands as well but I don't know how to do that. There might even be some way in minimal racket to convince those commands to be run. What does not work anymore is that one of the packages is blocked by the corporate proxy now as a "virus" so minimal racket it is. cheers bruce On 2022-06-18T18:06:54.000+02:00, knigh...@gmail.com wrote: > Hi all > > Is there a plain ZIP file for kind-of installing racket?

Re: [racket-users] Surprising but convenient
HI, It is a touch unclear what you mean by deleting the file and on which OS you are using. On Linux and similar OSes the rm command just calls the unlink system call. This removes the file from the directory and if the link count is now 0 then the file is removed from disk. But this last part happens only if the file is not open. If it open you get a situation where it is still on disk but not visible in any directory. As long as the process does not close the file then all is good. You can write and read to the file with no problems. But when the file is closed then the file will disappear from disk. More than once in my life there has been the "where did all the disk space go?" conversation that has resulted in a multi megabyte, multi gigabyte or now multi terabyte file being found and deleted. Without figuring out that it was open and therefore won't go away until some process is killed as well. Now none of the above could apply to Racket. One would need to know the gory details of how file writing is implemented. But this would explain what you see. cheers bruce On 2021-12-19T18:08:13.000+01:00, Sage Gerard wrote: > If I understand this correctly, there's a difference between > deleting a _reference_ to 50 GB (like an inode), and actually > writing 50 GB. > > When you write to an output port, you are writing to a buffer in > memory.

[racket-users] Racket on Corporate Desktop Windows
Hi, So for quite some while I have been running a minimal racket on my locked down windows desktop. Go to More Installers and Checksums and I grab the Windows 64bit x86-64 tar ball, untar it, and everyone is happy. But no GUI of course. Well I had been building on MacOS for years following the instructions to build a Minimal Racket and then run raco pkg install -i main-distribution and it finally clicked that the instructions were almost identical for Windows. raco pkg update --auto racket-lib raco pkg install -i main-distribution just like the instructions said. In my mind I thought "I don't have a build toolchain on Windows, so that won't work." And I was wrong. It works just fine on my locked down desktop and now I have a GUI Dr Racket as well. cheers bruce -- You received this message because you are subscribed to the Google Groups "Racket Users" group.

Re: [racket-users] Re: Installing Drracket on linux penguin on Chromebook
Hi, If the architecture is aarch64 then most likely you'll need to build from source. In the University of Utah snapshot builds there is an armv6 build, but most likely this won't work, but is worth trying. [https://www.cs.utah.edu/plt/snapshots/](https://www.cs.utah.edu/plt/snapshots/) Whether armv6 binaries work on aarch64 depends on kernel build options and having all the needed 32 bit arm libraries installed. What will not work at all is any x86 build. If the armv6 build does not work download the source plus built packages and untar. Then: cd src/ mkdir build cd build ../configure --prefix=whereyouwantthisinstalled make make install It takes about 600 meg once installed. You probably need a gigabyte free to do the build. Of course you have to have the assorted build tools and libraries installed as well. My builds take about 30-45 minutes or so cheers bruce > What's the result of `file > /home/user/racket-tmp-install/bin/racket` and the result of > `uname -a`? > > (In other words, what hardware are you using?

Hi Edurado, You could just download the linux source + built packages, and then cd racket-version cd src mkdir build cd build ../configure --prefix=where_do_you_want_to_install_racket make make install will build it for you. On one of my systems configure takes less than 10 seconds, make takes about 4 minutes, and a make install takes just over a minute.

[racket-users] Building Racket 7.5 CS on MacOS Catalina
Hi all, I normally build Racket from source, and, for 7.5 I decided to try Racket CS as well. Racket 7.5 builds fine from minimal source. Racket CS builds fine as well from minimal source, but, when I run the command to build the rest of the distribution. ./raco pkg install --deps search-auto -i main-distribution it fails with: Resolving "main-distribution" via [https://download.racket-lang.org/releases/7.5/catalog/](https://download.racket-lang.org/releases/7.5/catalog/) bytes-copy!: contract violation expected: (and/c bytes?

[racket-users] Technical Breakdown of a new NES game written in Lisp (dustmop.io)
Pointed to by hacker news (news.ycombinator.com) "Rather, a custom language was developed in tandem with the game. [Co2](https://github.com/dustmop/co2) is a Lisp-like language, built on Racket Scheme, which compiles into 6502 assembly. This language was originally started by [Dave Griffiths](https://twitter.com/nebogeo) to build the What Remains demo, and I decided to stick with it for the full project."

Re: [racket-users] Experiences with Racket on RISC-V?
Hi, The HiFive1 is a 32 bit integer only machine, sadly. I guess I must admit being a bit old to re-do software floating point. I still have nightmares of ARM and then later 68000 systems. Your right about the HiFive Unleashed would be a good system, but, expensive. There is a group out of China who is doing a RISC-V 64 bit with floating point. I've ordered one and we'll see what it looks like when it arrives. https://www.indiegogo.com/projects/sipeed-maix-the-world-first-risc-v-64-ai-module#/ The campaign seems closed, but, I'm sure if this works and the team doing this doesn't burn out they will start selling them somewhere. cheers bruce > These are pretty new, and the prices are higher than other ISAs with > economies-of-scale and mostly long-amortized development costs (and > there's perhaps no loss-leaders or dumping for market share or lock-in, > like we sometimes see in industry). > > The HiFive1 is more like a $60 Arduino or maybe RasPi: > https://www.sifive.com/boards/hifive1 > > The HiFive Unleashed, when combined with their Expansion Board, could be > used to make a workstation, but is pretty new, and costs thousands of > dollars: > https://www.sifive.com/boards/hifive-unleashed > > I've seen "RISC-V" USB dongle-like boards, but the ones I've seen are > just little FPGA experimenter boards burnt with RISC-V logic. > > That's what I found, last time I looked.
