jlafon··on Chemical space is really big (2014)
Many have commented here on the computational challenges of enumerating, storing, and searching very large virtual libraries. While molecules can be represented and stored as strings, that's an oversimplification of the problem (from a CS perspective). Scientists often want to search these large libraries in 2D and 3D, which requires computing & storing those coordinates. It can be cost prohibitive just to store the 3D coordinates for massive virtual libraries, even for large pharmaceutical companies. We've done this for 10^10 molecules [0].

jlafon··on Ask HN: Who is hiring? (November 2016)
OpenEye Scientific | Santa Fe, NM | Onsite/Fulltime | http://www.eyesopen.com/careers

OpenEye Scientific Software provides software to the Pharmaceutical Industry for molecular modeling and cheminformatics. It has done so since 1997 in its continuing mission to provide novel software, new science and better business practices to the industry. Central to our approach is the importance of shape and electrostatics as primary variables of molecular description, platform-independent code for high-throughput 2D and 3D modeling, and a preference for the rigorous rather than the ad hoc.

We have three open positions in Santa Fe, NM. Some of the technologies we use are Python, Go, C++, Django, Docker, and AWS. We are growing our small team and looking for talented backend engineers and DevOps engineers.

Santa Fe is a beautiful mountain town with excellent outdoor recreation (hiking, skiing, cycling) as well as art, music & food culture.

jlafon··on Prison phones are a predatory monopoly – One family fought back and won
First of all, I'm not defending what is obviously predatory. However, there is more involved then what you might think at first glance. Right or wrong, correctional facilities have reasons to discourage phone calls (context: I put myself through college working at a maximum security prison). Calls are supposed to be monitored (usually done manually) to prevent criminal business from being done on prison phones - and there are never enough people to listen to all calls. There are never enough phones either, which frequently causes tension between inmates using phones and those waiting for them. In higher security levels phones are labor intensive. An officer has to escort a (potentially dangerous) person from their cell to the phone, and stand there for the duration of the call. And to the article's point, it's such a problem that prepaid phone cards are a form of currency on the inside.
jlafon··on Ask HN: Who is hiring? (November 2015)
OpenEye Scientific Software (Santa Fe, New Mexico) - various positions: http://www.eyesopen.com/careers
jlafon··on Show HN: Bloop – Declarative Modeling for DynamoDB
Nice work. I implemented something very similar last year: https://github.com/jlafon/pynamodb.
jlafon··on Dynomite – Making Non-Distributed Databases Distributed
That makes sense. I had only seen the Memcache & Redis datastores being used (and both being comparable to DynamoDB).
jlafon··on Dynomite – Making Non-Distributed Databases Distributed
It's interesting that Netflix decided to write this rather than using Amazon's own DynamoDB. I wonder specifically if DynamoDB was too expensive (as I have found), or was there some other reason?
jlafon··on My experience with using cp to copy 432 million files (39 TB)
Author of the paper here. The file operations are distributed strictly without links, otherwise we could make no guarantees that work wouldn't be duplicated, or even that the algorithm would terminate. We were lucky in that because the parallel file system itself wasn't POSIX, so we didn't have to make our tools POSIX either.
jlafon··on Django Query Inspector
What I meant is that getting the toolbar to show up when you aren't serving from localhost isn't as trivial as setting DEBUG=True. It requires other settings (https://github.com/django-debug-toolbar/django-debug-toolbar...) which can be annoying to configure.
jlafon··on Django Query Inspector
I end up using Django Rest Framework (http://www.django-rest-framework.org/) generated UIs along with the debug toolbar, and then disabling the generated UIs when I'm done profiling.
jlafon··on Django Query Inspector
For those interested, here are a couple of differences between this and django-debug-toolbar (an excellent, widely used utility that also provides SQL inspection).

1. django-debug-toolbar can be difficult to enable if you aren't serving from localhost (for security reasons, because your settings are included in the UI). This project looks much simpler to enable, as you just set DEBUG=True in your settings.

2. django-debug-toolbar provides its information through a UI component embedded in your own UIs, but it doesn't help you with profiling HTTP APIs that don't have a UI. In contrast, this project puts some profiling information in the response headers, and SQL logs are sent to a logger. I think this use case is where Django Query Inspector shows a lot of utility.

jlafon··on OAuth 2.0 and OpenID Redirect Vulnerability
I'm trying to understand this too. This is only a problem if the OAuth provider (Google, Twitter, etc) does not validate the URL that the client is trying to redirect the user to after the user has authorized the app, correct?
jlafon··on Space Monkey dumps Python for Go
If you did a line for line transliteration, did you use any of Go's concurrency features such goroutines or channels? I ask because I find that when I translate a program from Python to Go that it's beneficial to structure the program differently so that I can use goroutines.
jlafon··on Pkgr.io: Easy way to get a Debian package out of any app
Well done. All of my questions were answered by browsing the site. +1 for using SSL everywhere.
jlafon··on Show HN: Mogo Chat – open-source team chat app written in Elixir and Ember.js
Out of curiosity, why did you choose Ember? For context, my team is evaluating Angular vs. Ember. Thanks.

jlafon··on Using Django for mostly static sites
The most interesting part to me is that there is no database. It had never occurred to me to use Django without one.
jlafon··on 1 In 4 Americans Thinks The Sun Goes Around The Earth, Survey Says
How can this be? Perhaps, their sample is biased? It would really be sad if 25% of Americans really have this misconception - not to mention the similarly high percentages for other countries.
jlafon··on What aspect of your Java programming is the biggest pain in the arse?
Java has many great features, but I find it to be too tedious for me to experiment. For example: want to read a file into a string? The Python version is open(name).read(), and I've never seen a Java equivalent be that concise.
jlafon··on Keybase.io
This looks pretty cool! I like the story flow.

You might want to include some links that explain what the keys are, what PGP is, etc - because not everyone who lands on your site will know.

jlafon··on Antetype – Design more beautiful UIs faster
This looks really powerful, and I'm glad you offer student pricing.
jlafon··on Show HN: Wagtail, our new Django CMS
Yeah, it's probably a developer focused mindset, but I'm a developer.

Without a test suite, it makes it very difficult for anyone to contribute, because there isn't a clear way to tell if they broke something. How do you decide to accept a pull request?

Then there is the entire issue of security. Without proper tests, how can you test that login/logout/sessions work? How can you tell if the csrf token is present? The list goes on.

What about databases? Does it work with Postgres? MySQL? How do you know?

I'll say it again, I think it's a cool project - but it needs tests. Tests are a developer's best friend.

jlafon··on Show HN: Wagtail, our new Django CMS
I wasn't counting the default django 1 + 1 test, but I did find one actual test. It's obvious that a lot of work was put into this, and I think it has potential. My suggestion to the creators is to start with tests from the beginning. However, it's not too late to start now and add tests for everything. It's a lot of work initially, but it will pay off for years to come.
jlafon··on Show HN: Wagtail, our new Django CMS
This looks interesting, but I can't take it seriously. From what I can tell, you haven't written any tests at all.
jlafon··on Show HN: Clinck – business card app. Type an email and send your card.
Or, I could send an email with my signature line, which includes most of that information. Am I missing something?
jlafon··on Python With Braces (The simple solution to PythonB)
What is the advantage of adding braces to Python? I find Python's indentation based syntax to be very readable, very close to pseudo code.
jlafon··on JetBrains C++ IDE: Status update and Video report
It looks very promising, but watch it on mute!
