box2 process terminated for old homepage
by Chris Cunnington 17 Mar '14

17 Mar '14

I went into box2 and killed the old homepage image. You can see the line that was the process here [1]. This also involved deleting the symlink as well. [2] The service directory in /home/website is now gone as well. The wildcard DNS routes unknown subdomain requests to some daemontools service for looking at old mailing lists. I don't think it's a process. It's some kind of cgi-bin thing. Check it out: http://foobar.squeak.org Deleting symlinks and service directories is a tad barbaric. I'm getting under svc -d /service/fooservice and such to stop services instead. But this is a sunset box. By St. Patrick's Day next year, it will be gone.

I've gone over the links on the homepage and they all work. The download links have been changed to the 4.5 all-in-one in the ftp repository. Have a nice weekend, Chris

Backlog of change requests in no particular order: Tim http://lists.squeakfoundation.org/pipermail/webteam/2014-March/001384.html Chris M. http://lists.squeakfoundation.org/pipermail/webteam/2014-March/001392.html http://lists.squeakfoundation.org/pipermail/webteam/2014-March/001399.html Eliot http://lists.squeakfoundation.org/pipermail/webteam/2014-March/001421.html squeak.org issues: - some image links are to chriscunnington.com - zip resources for faster download - use minified versions of files - put 4.5 announcement between Welcome To Squeak and Take Part In The Innovation - says 4.4 instead of 4.5 - get that 404 image (broken paper showing a code browser) out of my email Archive - explore wrapbootstrap.com for ideas - check multi platform layouts (i.e. cell phone, tablet) Update Procedure: I'm going to monopolize site update for the time being, as the update procedure is untried and specific to me. When it settles down we can change it. It works as follows. There is no in-server persistence. The persistence is Desktop persistence -- the master is on my desktop (backed up weekly; maybe I could put it in my Dropbox for people to access?). I change the site in localhost. I then zip the image and changes files for FTP upload. In /home/chriscunnington (someday I think we'll need a directory called /home/website) I execute a script called prepuploadediimage.sh. It looks like this: #!/bin/sh unzip squeak.org.zip rm -rf __MACOSX rm -rf /home/chriscunnington/squeak.org/.DS_Store rm -rf squeak.org.zip chmod 777 /home/chriscunnington/squeak.org/* ln -s /usr/lib/squeak/sources/SqueakV41.sources /home/chriscunnington/squeak.org/SqueakV41.sources There are two things to notice there, I'd say. The first is that the permissions are probably set too high. If anybody has a preference other than 777 (that works), then I'll implement it. The second thing is that Ken wanted to save space by having only one SqueakV41.sources file that people symlink to. Once the new image is in place ( and I guess I missed the part where I delete the old image before uploading) I kill the website process, which at the moment is owned by me. Daemontools restarts the process with the new image. I'm going to review the homepage first and change the download link to 4.5. Chris

final update -- DNS back to normal
by Chris Cunnington 14 Mar '14

14 Mar '14

I did a quick circuit around the subdomains and everything looks fine. Unless somebody sees something else that's been dropped, I'd say things are now back to normal. That being the case, I'll turn tomorrow to updating squeak.org with the backlog of requested changes on the webteam list. I have appreciated your patience and restraint in this matter. Time was. people's reactions could have gone a whole other way. I said as much today talking to Colin. Chris http://www.youtube.com/watch?v=Tsr-XtuKuSw

>I have taken the liberty to tinker with the dns stuff: >I changed the dns data file to: > * make box2 explicit > * point A for 'squeak.org' and 'www.squeak.org' to box4 > * point MX for 'squeak.org' to 'box2.squeakfoundation.org' > * point * to box2 >As soon as the caches update, everything should be fine again™ These changes look great. Thanks, Tobias! Chris

www.squeak.org Cog reference
by Eliot Miranda 13 Mar '14

13 Mar '14

Hi All, I love the look of www.squeak.org's front page, however I think the Cog part is out of date and not particularly helpful. May I make the following suggestions? 1. The text underneath "Cog JIT VM" would be better if it used the text from http://www.mirandabanda.org/cogblog/about-cog/ (see below) 2. the "Cog JIT VM" More... link goes to http://www.squeakvm.org/index.html, which is, I think, a non-sequitur, ecauser the page doesn't say anything obvious about Cog. If the page is to be kept then it needs to say at least "The Squeak Virtual Machine". But better might be to link directly to my blog. Here's the text from http://www.mirandabanda.org/cogblog/about-cog "Cog is a virtual machine designed for Smalltalk and other similar dynamic languages. Cog builds on the Squeak virtual machine adding a stack-to-register-mapping just-in-time compiler, aggressive in-line message cacheing and effective optimization of Smalltalk's first-class activation records. Cog is the virtual machine underlying Teleplace's Croquet-based enterprise virtual collaboration spaces software, the fastest virtual machine for Squeak, and for Gilad Bracha's Newspeak modular language inspired by Beta and Smalltalk. Like the original Squeak VM, Cog is implemented and developed in Smalltalk, and translated into a lower-level language to produce the production VM. Being a Smalltalk program it is a delight to develop. Cog is available under the MIT open source license and is unencumbered for commercial deployment. Cog's performance relative to the existing Squeak interpreter varies, depending on the benchmark chosen. As of early-2011, the Cog JIT uses strong inline cacheing techniques and stack-to-register mapping that results in a register-based calling convention for low-arity methods. Due to the complexity of the Squeak object representation it has a limited set of primitives implemented in machine code that, for example, exclude object allocation. Performance of the early-2011 JIT for the nbody, binarytrees and chameneos redux benchmarks from the computer language shootout is in the range of 4 to 6 times faster than the interpreter. I am writing an occasional series of blog posts describing the implementation on this site. See the Cog category at the left side of the page. Currently I'm working on a new memory manager with a much improved object representation and garbage collector. See the Spur category at the left side of the page. Cog is now the standard VM for Squeak, Pharo and Newspeak." -- best, Eliot

update 1 -- intermezzo
by Chris Cunnington 12 Mar '14

12 Mar '14

It's been brought to my attention that I've been reading the Makefile in box2 wrong. This is certain, because I though the symbols were BASH. They're not. Makefile has it's own, apparently. cat Makefile data.cdb: data /usr/bin/tinydns-data rm data data: data.in cdegroot-secondary.data.in cat $? >$@ I've been concerned with the first part. The second part is about this file [1] which has not been updated since 2007. I think it can be ignored. Try this: http://www.cdegroot.com/ Though I will admit I just had to open Intro To GCC to grok how wrong I was about how Makefiles work. I'm of the opinion that this part of the Makefile is legacy and can be removed. I have to go to an appointment and will be away for several hours. Chris [1] cat cdegroot-secondary.data.in .cdegroot.com:85.10.192.171:a .cdegroot.com:85.10.195.197:b @cdegroot.com:85.10.192.171:a +cdegroot.com:85.10.192.171 +*.cdegroot.com:85.10.192.171 # .klickt.info:85.10.192.171:a .klickt.info:85.10.195.197:b @klickt.info:85.10.192.171:a +klickt.info:85.10.192.171 +*.klickt.info:85.10.192.171 # .stephaniebaquet.com:85.10.192.171:a .stephaniebaquet.com:85.10.195.197:b @stephaniebaquet.com:85.10.192.171:a +stephaniebaquet.com:85.10.192.171 +*.stephaniebaquet.com:85.10.192.171 # .noriensiemons.info:85.10.192.171:a .noriensiemons.info:85.10.195.197:b @noriensiemons.info:85.10.192.171:a +noriensiemons.info:85.10.192.171 +*.noriensiemons.info:85.10.192.171

update 1
by Chris Cunnington 12 Mar '14

12 Mar '14

OK, I've updated /etc/service/tinywiki/data.cdb on box2. 1. I added a 3600 second TTL to all squeak.org subdomains. 2. I commented out the wildcard and added separate lines for each of the following services: ftp; bugs; wiki; map; www; and, source. It's an anomaly of the Makefile on box2 that it deletes the file called data, which I was just editing, so I cannot copy and past it here at the moment. I'll do it on the next rev. The current TTL is 86400, so I imagine that will take 24 hours to completely flush out before hourly iteration can begin. Thank you for your patience, Chris

squeak.org configured for nginx
by Chris Cunnington 12 Mar '14

12 Mar '14

http://box4.squeak.org I've done the first of two parts. I've changed the config file nginx.conf to proxy to the running image. [1] In strict terms, since the port number has been removed (i.e. It is no no longer box4.squeak.org:8624) the image is deployed. Unfortunately, without a "www" subdomain or no subdomain (i.e. http://squeak.org) not many people are going to find it. Thus I now turn to tinydns. When that's done, it's deployed. Chris [1] I copied default.conf into default.conf_master. I then hacked default.conf, which now contains only: server { listen 80; server_name *.squeak.org; location / { proxy_pass http://127.0.0.1:8624; } }
