unfortunately continued to work on setting up julia (there are one or two threads on their mailing list, I have a script for precompilation, etc.) – and I also learned that their upcoming 0.5 release is compiling even slower.
helped gregory with 3d plotting
did catch the "drop files" vs. "drop text" issue and while doing that, discovered that it doesn't work everywhere. anyways, #826 is closed and it took me more than 15 minutes to finish it, because I made a typo in length.
helping jack didn't help, but now I know how pushing works: it's git@ and not git://
William Stein
Wrote and gave a talk about Sage to about 30 people: https://youtu.be/wOCYTLdvVDM
Tried to make the SMC 3d rendering support the colormap option; I failed (issue https://github.com/sagemathinc/smc/issues/829)
Plan tonight:
- help jlee setup local VirtualBox machines for faster development to reduce load on the network
- finish kubernetes service account control, to make containers more secure (they are wildly insecure on GCE by default!)
- finish uploading all projects to google cloud storage (should be done by 7pm!); maybe then delete (5TB of disk)

Kartik Venkatram

2016-08-18

What do you plan to do today?

IDEAS - review Jack's ticket and if it is fine, put it into the positive review state

People - Jennifer Balakrishnan - sort out Aly and Kartik's housing - set up 7.4.beta0 for student computing twists of p-adic L-functions using OMS - trac #8441 - Gregory Bard - Working on both graphing and the appendix to Sage for Undergraduates. - I should harmonize the syntax of my new plotting commands with the old ones, to the extent possible. - I should make sure as many of the options available with the old commands are available with the new commands. - I should begin documenting (with examples) the new functions. - I need to read Jack Kennedy's remarks on the graphical appendix. - I'm going to split it into two appendices, because a 65-page appendix with 12 sections is intimidating.

Alina Bucur
- snorkled
- brought snacks to campus
- sent course management feedback to william and harald
Tim Clemans
seen on the sidewalk... probably still installing linux?
Aly Deines
- Rebased 16339, please review! (caching hecke modules)
- Working on rebasing an older ticket 16893 -- wrapping pari's pseudobasis
- Snorkeled until chilly, chased a sea turtle from an appropriate distance.
John Jeng
hiked, reddit.
food -- more burgers.
fix one bug, maybe.
Kiran Kedlaya
used GCE; not enough RAM.
Jack Kennedy

not much today so far (but the night is young)
read a bit of subgraph paper
looked at existing subgraph code
hiked
napped

Jonathan Lee
hiked; redid url routing for react SMC -- more consistent code.
Simon Luu
- trying to get it so when you open side chat, it will grab all media streams of everyone currently broadcasting and renders it on the page. Struggling because smc dev server taking a long time to load and it keeps giving the red something bad has happened page.
Michelle Manes
- AC response.
Nicholas Ruhland
hiked; nothing very relevant; other stuff.
Harald Schilly
breakfast discussion with william about kubernetes rewrite.
made http://public-cloud.sagemath.com/ as a demo for GCS backed public files for projects (only the GCS side of things) -- Where?
manola falls
William Stein
breakfast triage with hsy about k8s.
lunch discussion with kiran and kartik about GCE, GF2 linear algebra.
hike & swim
kartik & i: worked on installing SMC on CentOS 7 and creating docker image of full SMC.
Vivek Venkatachalam
issue with dev
Kartik Venkatram
Made more progress on running SMC on centos, but switching to getting an ubuntu docker image working
Thoughts on names
Some ideas for faster computation of char poly of binary matrices for Kiran -- Krylov.

What do you plan to do today?

Gregory Bard
cleaning up last few sections of appendix.
Alina Bucur
???
Tim Clemans
find a file
project log cursor (need a little help)
Aly Deines
rebasing and merging. sigh.
Rob Harron
teaching
John Jeng
asleep or running. react rewrite
Kiran Kedlaya
experiment with GCE and with sparse vs. dense linear algebra over F_2
Jack Kennedy
☞ learn to develop SMC ☜
still looking at subgraph code
Jonathan Lee
react rewrite
Simon Luu
finish video chat
Michelle Manes
teaching
Nicholas Ruhland
??
Harald Schilly
setup http://blog.sagemath.com/
trying to finish that build script for compute images, like in the past few days
tim could teach me a few jenkins tricks
may try again to use dask or ipython parallel to distribute some tasks
William Stein
docker image of single-container SMC (with Kartik)
do the most difficult task involving kubernetes that will benefit from having @hsy around: ssh gateway

What did you do today?

Gregory Bard
- Finished writing all the possibilities for saving your image files. (Appendix G.4)
- Finished writing about the several uses of the show() command (Appendix G.5)
- Discussed linear algebra with Kiran Kedlaya
- Rewrote the code for newPlot3d to be more similar to the old plot3d
- Learned how to use **kwargs to enable passing keywords from newPlot3d to implicit_plot_3d, resulting in a tremendously simpler set of options
- Combined all five operations: 3d graphs where z=real_part, z=imag_part, z=magnitude, z=phase, and z="magnitude but color=phase".
- Rethinking how to organize H.1 (Basic 3D Plots in Cartesian Coordinates)
- Investigating contours=[] option in implicit_plot3d, to draw concentric hemispheres or paraboloids
- Found very cool examples for concentric hemispheres/paraboloids
- Found very cool examples for terrain-style maps z=f(x,y) colored by a terrain map T(x,y,z)=z
- Re-re-thinking how to organize H.1
- Panicking about the complex analysis section
- Proofread G.3, contour plots and density plots, including this huge microeconomics example.
- People, take a look at this link, if you are curious:
Alina Bucur
Tim Clemans
Aly Deines
- Rebased and cleaned up 16893. Please review my ticket!
Rob Harron
John Jeng
Kiran Kedlaya
Experimented with GCE and with sparse vs. dense linear algebra over F_2 (outcomes: GCE takes some getting used to but is very usable for someone at my skill level; dense LA over F_2 beats sparse handily in my problem range, say 5000x5000 matrices)
With Kartik, looked into why computing Hecke operators uses so much memory
Worked on a couple of tickets (11516, 20788)
Jack Kennedy

- Got all the media stream stuff all worked out. I just have to make it render one big video and the rest small videos. So that when you click on one of the small ones, it becomes the big video.
Nicholas Ruhland
Harald Schilly
http://blog.sagemath.com is now kind of ready for use. some template tweaks, and other details missing. content could be from the wiki, as a nice start

looked more into parallelization utilities. the award for the weirdest error message goes to ipyparallel and looks like this:

�cipyparallel.serialize.canning
CannedFunction
q)�q}q(UclosureqNUcodeqcipyparallel.serialize.codeutil
code_ctor
q(KKKKCUtd�}||tSqNUx�qUvarq Uy�q
Ubuffersq]ub.

and finally, a neat python 1-liner: this defines the @distribute decorator discussed a bit with kiran, based on ipyparallel's load balancer: distributed = lambda f : lambda vals : dict(zip(vals, lb.map_sync(f, vals, ordered=False))) used like this @distributed def computation(k): return 2*k + 1
```
computation(range(10)) →
{0: 2, 1: 4, 2: 6, 3: 8, 4: 10, 5: 12, 6: 14, 7: 16, 8: 18, 9: 20}
```
spied a bit on william's new dockerimage setup for distributing a full smc install for a single install
William Stein
Created a complete docker image of SMC for doing offline development, hosting your own SMC easily, etc. To use it, you (1) install docker, then (2) type docker run -P williamstein/sagemathcloud...
- Source code: https://github.com/sagemathinc/smc/tree/master/src/dev/docker
- Docker hub: https://hub.docker.com/r/williamstein/sagemathcloud/
- Worked super hard to do this for Kartik, but he had to leave just as I finished; but maybe tomorrow...
Evening plan: ssh gateway
Kartik Venkatram
something with GF2 linear algebra

Mostly work remotely
Continue to experiment with GCE and linear algebra (particularly, finish off a long-running computation from earlier this summer)
Try to pin down the issue Kartik and I found with the Cremona modular symbols wrapper (#21303)
Work on other tickets (suggestions welcome!)
Pack for the trip home
Jack Kennedy: fly back to Seattle ALOHA! and thanks for all the ~~fish~~
