-<user01> yeah
-<pjotrp> OK, that means you set the key correctly for that one :)
-<pjotrp> alright we are at the same state now. You can see most packages need
-         to be rebuild because they are no longer cached as binaries on hydra
-                                                                        [07:18]

-<pjotrp> export
-         PATH="/home/wrk/.guix-profile/bin:/home/wrk/.guix-profile/sbin":$PATH
-<pjotrp> to keep things like 'screen' from Debian
-<pjotrp> Once past building guix itself that is normally OK  [07:21]
-<user01> ah, okay
-<user01> will do that
-<pjotrp> the guix build requires certain versions of tools, so you don't want
-         to mix foreign tools in  [07:23]
-<user01> makes sense  [07:24]
-<pjotrp> On my laptop I am trying the main updating list of substitutes from
-         'http://hydra.gnu.org'...  10.5%  [07:27]
-<pjotrp> it is a bit slow, but let's see if there is a difference with the
-         mirror
-<pjotrp> you can see there are two servers here. Actually with recent daemons,
-         if the mirror fails it will try the main server  [07:28]
-<pjotrp> I documented the use of a caching server here  [07:29]
-<pjotrp> https://github.com/pjotrp/guix-notes/blob/master/REPRODUCIBLE.org
-<pjotrp> this is exactly what we are doing now
-<user01> alrighty  [07:35]
-<pjotrp> To see if a remote server has a guix server running it should respond
-                                                                        [07:36]

-<pjotrp>
-<pjotrp> you see that?
-<user01> yes  [07:37]
-<pjotrp> good. The main hydra server is too slow. So on my laptop I forced
-         using the mirror with  [07:38]
-<pjotrp> env GUIX_PACKAGE_PATH=../guix-bioinformatics/ ./pre-inst-env guix
-         package -i genenetwork2 --dry-run

-<pjotrp>
-<pjotrp> the list looks the same to me  [07:40]
-<user01> me too
-<pjotrp> note that some packages will be built and some downloaded, right?
-                                                                        [07:41]
-<user01> yes
-<pjotrp> atlas is actually a binary on my system  [07:43]
-<pjotrp> I mean in that list
-<pjotrp> so, it should not build. Same as yours?
-<user01> yeah, atlas and r-gtable are the ones to be downloaded
-<pjotrp> You should not have seen that error ;)
-<pjotrp> we should try and install it this way, try  [07:44]

-         package -i genenetwork2 --cores=4 --max-jobs=4 --keep-going  [07:46]
-<pjotrp> set CPUs and max-jobs to something sensible
-<pjotrp> Does your VM have multiple cores?
-<pjotrp> note you can always press Ctrl-C during install
-<user01> it doesn't, I'll reboot it and give it another core  [07:47]

-<user02> I'm here
-<user02> Will be stepping away for some breakfast

-<user02> Yes, I can

-<pjotrp> I don't need to build anything  [07:57]
-<pjotrp> (this won't work for you, yet)
-<pjotrp> to get it to work you need to 'trust' it   [07:58]
-<pjotrp> but, first get the build going
-<pjotrp> I'll have a coffee while you and get building
-<user01> yeah it's doing its thing now  [08:01]
-<pjotrp> cool  [08:02]
-<pjotrp> in a separate terminal you can try and install with the gn mirror
-                                                                        [08:05]

-<user01> alright
-<pjotrp> should be in the E-mail  [08:09]
-<pjotrp> getting it working it kinda nasty since the server gives no feedback
-<pjotrp> it works when you see no more in the build list ;)  [08:11]
-<pjotrp> btw, you can install software in parallel. Guix does that.
-<pjotrp> even the same packages
-<pjotrp> so keep building ;)
-<pjotrp> try and do this with Debian...
-<pjotrp> coffee for me  [08:12]
-<user01> the first build failed                                                                        [08:15]
-<pjotrp> OK, Dennis fixed that one yesterday  [08:27]
-<pjotrp> the problem is that sometime source tarballs disappear  [08:28]
-<pjotrp> R is notorious for that
-<user01> haha, that's inconvenient..
-<pjotrp> well, it is good that Guix catches them
-<pjotrp> but we do not cache sources
-<pjotrp> binaries are cached - to some degree - so we don't have to rebuild
-         those  [08:29]
-<pjotrp> time to use the guix cache at guix.genenetwork.org
-<pjotrp> try and install the key (it is in the E-mail)

-         --substitute-urls=http://guix.genenetwork.org --dry-run
-<pjotrp> should be all binary installs
-<user01> it's not..  [08:32]
-<user01> if I remove --substitute-urls, the list changes, does that mean I
-             have the key set up correctly at least?  [08:33]
-<pjotrp> dunno  [08:35]
-<pjotrp> how many packages does it want to build?
-<pjotrp> should be zero
-<user01> four
-<pjotrp> Ah, that is OK - those are default profile things
-<user01> genenetwork2 is among the ones to be downloaded so  [08:36]
-<pjotrp> remove --dry-run
-<pjotrp> yeah, good sign :)
-<pjotrp> we'll still hit a snag, but run it
-<pjotrp> should be fast

-<user01> it worked!  [08:38]

-<user01> complains about not being able to connect to the database  [08:41]
-<pjotrp> last snag :)
-<pjotrp> no database
-<pjotrp> well, we succeeded in installing a same-byte install of a very
-         complex system :)  [08:42]
-<pjotrp> (always take time to congratulate yourself)
-<pjotrp> now we need to install mysql
-<user01> hehe :)
-<pjotrp> this can be done throug guix or through debian  [08:43]
-<pjotrp> the latter is a bit easier here, so let's do that
-<pjotrp> fun note: you can mix debian and guix
-<pjotrp> Follow instructions on   [08:44]
-<pjotrp>
-         https://github.com/genenetwork/genenetwork2/tree/staging/doc#run-mysql-server
-<pjotrp> apt-get install mysql-common  [08:45]
-<pjotrp> may do it
-<pjotrp> You can also install with guix, but I need to document that
-<pjotrp> btw your internet must be fast :)  [08:46]
-<user01> hehe it is ;)
-<pjotrp> when the database is installed  [08:48]
-<pjotrp> be sure to set the password as instructed  [08:50]
-<pjotrp> when mysql is set the genenetwork2 command should fire up the web
-         server on localhost:5003  [08:58]

-<pjotrp> say for r-prepocesscore
-<pjotrp> download or build?
-<pjotrp> mine says download  [09:26]
-<user02> it only lists the derivatives to be built
-<user02> nothing else happens  [09:27]
-<pjotrp> OK, so there is a problem
-<pjotrp> your key may not be working
-<pjotrp> everything should be listed as 'to be download'  [09:28]
-<user02> Hmm
-<user02> Ah
-<user02> I know where I messed up
-<pjotrp> where?
-<user02> I did add the key
-<user02> However
-<pjotrp> (I am documenting)
-<user02> I did not tell guix to trust it
-<pjotrp> yes
-<pjotrp> and there is another potential problem
-<user02> Remember the documentation on installing guix?
-<user02> You have to tell guix to trust the default key  [09:29]
-<user02> Right?
-<user02> So in this case
-<pjotrp> read the IRC log
-<user02> That step is mandatory
-<pjotrp> user01: how are you doing?

-<pjotrp>
-<user03> pjotrp: Possibly we should use the archive utility of Guix to do
-        deployment to avoid such out-of-sync differences :)  [09:34]
-<pjotrp> maybe. I did not get archive to update profiles properly  [09:37]
-<pjotrp> Also it is good that they get to understand guix
-         this way
-<pjotrp> carved in stone, eh  [09:38]
-<user02> Yeah, all good  [09:39]
-<user02> My mistake was skipping the guix archive part
-<user02> Can we begin with the install?
-<user02> It's telling me of derivatives that will be downloaded  [09:40]
-<user02> So we're good
-<user02> Here goes
-<pjotrp> yeeha  [09:42]
-<user02> pjotrp, where is this guix.genenetwork.org located at?
-<pjotrp> Tennessee
-<user02> It's...it's....sloooooooowwwwwwwwwwwwww
-<pjotrp> not from Europe
-<pjotrp> is it downloading at all?
-<user02> It should be extended
-<user02> Yes...like at 100KB/s  [09:43]
-<user02> tear-jerker
-<user02> Verizon problems
-<user02> who's the host?
-<pjotrp> I am getting 500Kb/s
-<pjotrp> UT
-<user02> Guix's servers can run off more than one server, right?
-<user02> I'd like to host that particular server here
-<user02> For speed
-<pjotrp> yes
-<user02> Sooner or later
-<user02> It will be a necessity  [09:45]
-<pjotrp> exactly what I am doing - this is our server
-<pjotrp> guix.genenetwork.org:8080
-<user02> All done installing  [09:46]
-<pjotrp> what?
-<user02> Now the databases
-<pjotrp> what do you mean by slow exactly?
-<user02> Yes, it's installed
-<pjotrp> can you run genenetwork2
-<user02> setting variables
-<user02> If I try running it now, it will fail as I don't have the DBs  [09:47]
-<pjotrp> cool - you had a lot of prebuilt packages already
-<pjotrp> OK, follow the instructions I wrote above
-<user01> now everything seems to be working for me :)
-<user02> OK
-<pjotrp> user01: excellent!
-<pjotrp> you see a webserver?
-<user01> yep, can connect to localhost:5003  [09:48]
-<pjotrp> So now you are running a guix copy of GN2
-<pjotrp> you can see where it lives with `which genenetwork2` or ls -l
-         ~/.guix-profile/bin/genenetwork2  [09:49]
-<pjotrp>
-         /gnu/store/1kma5xszvzsvmbb4k699h7gvdncw901i-genenetwork2-2.0-a8fcff4/bin/genenetwork2
-<pjotrp> it is a script
-<pjotrp> written by guix, open it  [09:50]
-<pjotrp> inside it points to paths and our script at
-<pjotrp>
-         /gnu/store/1kma5xszvzsvmbb4k699h7gvdncw901i-genenetwork2-2.0-a8fcff4/bin/.genenetwork2-real
-<pjotrp> if you open that you can see how the webserver is started  [09:51]
-<pjotrp> next step is to run a recent version of GN2
-<user01> okay  [09:52]
-<pjotrp> See
-         https://github.com/genenetwork/genenetwork2/tree/staging/doc#run-your-own-copy-of-gn2
-<pjotrp> but do not checkout that genetwork2_diet
-<pjotrp> we reverted to the main tree
-<pjotrp> clone git@github.com:genenetwork/genenetwork2.git  [09:53]
-<pjotrp> instead and checkout the staging branch
-<pjotrp> that is effectively my branch  [09:54]
-<pjotrp> when that is done you should be able to fire up the webserver from
-         there  [09:55]
-<pjotrp> using ./bin/genenetwork2
-<user02> now installing DBs
-<user02> Downloading
-<pjotrp> annoyingly the source tree is ~700Mb  [09:56]
-<user02> Can it also be done by installing the guix package
-         genenetwork2-database-small?
-<pjotrp> I changed it in the diet version to 8Mb, but I had to revert
-<user01> I need to make my VM bigger...
-<pjotrp> user02: not ready  [09:57]
-<user02> ok
-<pjotrp> user01: sorry
-<pjotrp> user01: you could mount a local dir inside the VM for development
-<pjotrp> that would allow you to use MAC tools for editing
-<pjotrp> just an idea
-<user01> yeah, I figure I'll do something like that
-<pjotrp> do you use emacs?  [09:58]
-<user01> yep
-<pjotrp> that can also run on remote files over ssh
-<pjotrp> that's an alternative
-<pjotrp> kudos for using emacs :), wdyt user03
-<user02> 79 minutes to go downloading the db
-<pjotrp> user02: sorry about that  [09:59]
-<pjotrp> it is 2GB
-<user02> user, you can also mount the directory via sshfs
-<user02> Mac OSX runs OpenSSH
-<pjotrp> user02: sopa
-<user02> You can therefore mount a directory outside the VM to the VM via
-         sshfs  [10:00]
-<pjotrp> yes, 3 options now
-<user02> That way, you can set up a VM only for it's logic
-<user02> Apps + the OS it runs  [10:01]
-<user02> For data, let it reside on physical host accessible via sshfs
-<user02> Use this Arch wiki reference:
-         https://wiki.archlinux.org/index.php/SSHFS
-<user02> I edited that last somewhere in 2015, may have been updated since
-         then
-<user01> alright, cool!  [10:04]
-<pjotrp> user01: you are almost done  [10:06]
-<pjotrp> I wrote an elixir package for guix :)
-<pjotrp> env GUIX_PACKAGE_PATH=../guix-bioinformatics/ ./pre-inst-env guix
-         package -A elixir
-         --substitute-urls="http://guix.genenetwork.org"   [10:08]
-<pjotrp> elixir  1.2.3   out
-         ../guix-bioinformatics/gn/packages/elixir.scm:31:2
-<pjotrp>
-<pjotrp> I am building it on guix.genenetwork.org right now  [10:09]
-<user01> nice  [10:10]

@@ -41,3 +41,58 @@ JS_GN_PATH (3) is for development purposes. By default is is set to
 $HOME/genenetwork/javascript. Say you are working on an updated
 version of a JS module not yet in (1) you can simply check out that
 module in that path and it should show up.
+
+* Python modules
+
+Python modules are automatically found in the Guix profile.
+
+For development purposes it may be useful to try some Python package.
+Obviously this is only a temporary measure and when you decide to
+include the package it should be packaged in [[http://git.genenetwork.org/guix-bioinformatics/guix-bioinformatics][our GNU Guix software
+stack]]!
+
+To add packages you need to make sure the correct Python is used (currently
+Python 2.7) to install a package. E.g..
+
+#+BEGIN_SRC sh
+python --version
+  Python 2.7.16
+pip --version
+  pip 18.1 from /usr/lib/python2.7/dist-packages/pip (python 2.7)
+#+END_SRC
+
+You can install a Python package locally with pip, e.g.
+
+#+BEGIN_SRC sh
+pip install hjson
+#+END_SRC
+
+This installed in ~$HOME/.local/lib/python2.7/site-packages~. To add
+the search path for GeneNetwork use the environment variable
+
+#+BEGIN_SRC sh
+export PYTHON_GN_PATH=$HOME/.local/lib/python2.7/site-packages
+#+END_SRC
+
+Now you should be able to do
+
+#+BEGIN_SRC python
+import hjson
+#+END_SRC
+
+In fact you can kick off a Python shell with something like
+
+#+BEGIN_SRC python
+env SERVER_PORT=5013 WEBSERVER_MODE=DEBUG LOG_LEVEL=DEBUG \
+  SQL_URI=mysql://gn2:webqtl@localhost/db_webqtl_s \
+  GN2_PROFILE=~/opt/genenetwork2 \
+  ./bin/genenetwork2 ./etc/default_settings.py -c
+Python 2.7.17 (default, Jan  1 1970, 00:00:01)
+[GCC 7.5.0] on linux2
+Type "help", "copyright", "credits" or "license" for more information.
+>>> import hjson
+#+END_SRC
+
+It should now also work in GN2.
