Reading/writing 3D STL files with numpy-stl
As a followup of my earlier article about reading and writing STL files with Numpy, I’ve created a library that can be used easily to read, modify and write STL files in both binary and ascii format. The library automatically detects whether your file is in ascii or binary STL format and is very fast due to all operations being done by numpy. First, install using pip or easy_install: pip install numpy-stl # Or if you don't have pip available easy_install numpy-stl Note that numpy numpy and python-utils version 1.6 or greater are required. While these should both be installed automatically by pip/easy_install, for numpy it’s generally recommended to download a binary release so it installs a bit faster. Example usage: https://github.com/WoLpH/numpy-stl from stl import stl mesh = stl.StlMesh('some_file.stl') # The mesh normals (calculated automatically) mesh.normals # The mesh vectors mesh.v0, mesh.v1, mesh.v2 # Accessing individual points (concatenation of v0, v1 and v2 in triplets) mesh.points[0] == mesh.v0[0] mesh.points[1] == mesh.v1[0] mesh.points[2] == mesh.v2[0] mesh.points[3] == mesh.v0[1] mesh.save('new_stl_file.stl') Documentation can be found here: http://numpy-stl.readthedocs.org/en/latest/ Please let me know if you have any problems using it or just to tell me that you like the project Link to this post! -
Django Logging Configuration: How the Default Settings Interfere with Yours
My colleague Vinod recently found the answer on Stack Overflow to something that's been bugging me for a long time - why do my Django logging configurations so often not do what I think they should? Short answer If you want your logging configuration to behave sensibly, set LOGGING_CONFIG to None in your Django settings, and do the logging configuration from scratch using the Python APIs: LOGGING_CONFIG = None LOGGING = {...} # whatever you want import logging.config logging.config.dictConfig(LOGGING) Explanation The kernel of the explanation is in this Stack Overflow answer by jcotton; kudoes to jcotton for the answer: before processing your settings, Django establishes a default configuration for Python's logging system, but you can't override it the way you would think, because disable_existing_loggers doesn't work quite the way the Django documentation implies. The Django documentation for disable_existing_loggers in 1.6, 1.7, and dev (as of January 8, 2015) says "If the disable_existing_loggers key in the LOGGING dictConfig is set to True (which is the default) the default configuration is completely overridden." (emphasis added) That made me think that I could set disable_existing_loggers to True (or leave it out) and Django's previously established default configuration would have no effect. Unfortunately, that's … -

We’re launching a Django code school: Astro Code School
One of the best ways to grow the Django community is to have more high-quality Django developers. The good news is that we’ve seen sharply increasing demand for Django web applications. The challenge that we and many other firms face is that there’s much higher demand than there is supply: there aren’t enough high-quality Django developers. We’ve talked about this issue intensely internally and with our friends while at DjangoCon and PyCon. We decided that we can offer at least one solution: a new Django-focused code school. We’re pleased to announce the launch of Astro Code School in Spring 2015. Astro will be the first Django code school on the East Coast. Programs include private trainings and weekend, 3-week, and 12-week full-time courses. In addition to Django, students will learn Python (of course), HTML, CSS, and JavaScript. They will come away being able to build web applications. The shorter programs will be geared towards beginners. The longer program will are for those with previous programming experience. Astro will also provide on-site, private corporate training, another area we frequently get asked about. Astro will be a separate company under Caktus. To support Astro, we welcome Brian Russell, the new director of … -

Why I Love Technical Blogging
I love writing blog posts, and today I’m setting out to do something I’ve never tried before: write a blog post about writing blog posts. A big part of our mission at Caktus is to foster and help grow the Python and Django development communities, both locally and nationally. Part of how we’ve tried to accomplish this in the past is through hosting development sprints, sponsoring and attending conferences such as PyCon and DjangoCon, and building a knowledge base of common problems in Python and Django development in our blog. Many in the Django community first get to know Caktus through our blog, and it’s both gratifying and humbling when I meet someone at a conference and the person thanks me for a post Caktus wrote that helped him or her solve a technical problem at some point in the past. -

Why you should donate to the Django fellowship program
Disclaimer: I do not represent the Django Software Foundation in any way, nor has anything below been endorsed by the DSF. The following opinions are my own, unsolicited rambling. If you hadn’t been looking for it specifically, you may have missed it. The Django Softare Foundation is running a fundraising effort for the new Django Fellowship program. It sounds like they’re still trying to figure out how to get the word out, so I wanted to do what I could to tell you why you should chip in. This particular blog post is going to focus on encouraging (peer-pressuring) commercial Django users in particular, though enthusiasts are welcome to read along! Humble beginnings Django is free and open source. Just provide the expertise and the infrastructure and you can build just about whatever web powered contraption you’d like. So you end up doing just that. Your first stop is the Django tutorial, written and maintained by a community of volunteers (just like the rest framework itself). You stumble along, slowly at first. Perhaps you find yourself frustrated at times, or maybe things move along at a faster pace. In no time, you’ve got "Hello World!" rendering, and here comes a business idea! One hundred lines of … -
Caktus is looking for a Web Design Director
Over the last two years Caktus’ design portfolio has rapidly been growing. We’ve taken on new projects primarily focused on design and have received community recognition for those efforts. We are happy to have grown our design capabilities to match the level of quality we demand from our Django developers. We have found it’s important to have strength on both sides of the table as each side challenges the other and forces the final product of our process to be as high quality as possible. In an effort to continue to push ourselves and expand our web design skill sets, Caktus is looking to hire a new Web Design Director. We’re searching for someone who can do a bit of wireframing and user experience and then has the tools necessary to design and code pages. We’re looking for someone who is attune to both form and function and knows where to focus depending on clients’ needs. Caktus is committed to doing good in our development communities as well as through the projects that we choose to work on, so we are also interested in finding someone who is engaged in the design community. If you or someone you know would … -

Introducing High Performance Django Expert Sessions
With the launch of our book, High Performance Django, we’ve received a number of inquiries from people asking for advice, for which the answers are too specific to their application to give good general advice, and too short to sign a consulting engagement. Rather than decline to help, we now offer Expert Sessions - a one-hour online consultation with a member (or members) of the Lincoln Loop team. Schedule an Expert Session and we'll meet up with you via Google Hangouts, Skype, or phone to answer any questions or provide expertise on building and scaling your complex Django application. In the past, we've answered such questions as: What technologies should we use for building a complex, high-performance application? Our app is super complex and it takes us 3 days to onboard a new developer. How can we simplify things to speed up onboarding? Should we move our infrastructure to Amazon Web Services or Heroku? What are the benefits and how do we perform the correct analysis? How can we make our deploys more reliable? How do we move from our legacy system to Django in order to improve reliability and cut costs? Should we use MongoDB or Redis? How do … -

Self-Hosted Server Status Page with Uptime Robot, S3, and Upscuits
For quite a while I've had a public "Status" page online for WhisperGifts via Pingdom. It basically just shows uptime over the past few days, but given my site is relatively low-volume and not ovely critical to my customers, the $10/month for Pingdom was actually one of my largest expenses after hosting. So, I started looking for an alternative. Today I re-deployed the WhisperGifts Status Page using a combination of Uptime Robot, Upscuits and Amazon S3. In short, I have Uptime Robot checking the uptime of my site (including it's subsites, such as the admin and user pages). The statistics are gathered and presented by Upscuits, which is entirely client-side JavaScript hosted on S3. My basic todo list for next time: Sign up for Uptime Robot. I'd been using them for ages on their Free plan as a backup to Pingdom; this gives 5-minute checks. Their paid plan gives 1-minute resolution. Add your sites, make sure they're being monitored correct. On the Uptime Robot dashboard, click My Settings. Open the section labelled Monitor-Specific API Keys and search for your Monitor. Copy the API key to a text file for later; repeat this step for subsequent monitors you want to include … -

Building Django proxies and MUD libraries
2015 is here and there is a lot of activity going on in Evennia's repository, mailing list and IRC channel right now, with plenty of people asking questions and starting to use the system to build online games.We get newcomers of all kinds, from experienced coders wanting to migrate from other code bases to newbies who are well versed in mudding but who aim to use Evennia for learning Python. At the moment the types of games planned or under development seems rather evenly distributed between RPI-style MUDs and MUSH games (maybe with a little dominance of MUSH) but there are also a couple of hack-and-slash concepts thrown into the mix. We also get some really wild concepts pitched to us now and then. What final games actually comes of it, who can tell, but people are certainly getting their MU*-creative urges scratched in greater numbers, which is a good sign. Since Christmas our "devel" branch is visible online and is teeming with activity. So I thought I'd post an summary about it in this blog. The more detailed technical details for active developers can be found on Evennia's mailing list here (note that full docs are not yet written … -
Mirroring my article on Chennai 36 – The Alumni Blog of IITM
Recently, I wrote an article to Chennai36 which is a blog maintained by the Alumni Association of IITM. The article was about my opinions on how to apply to graduate school for an undergrad at IITM. In this post, I am mirroring that article on this blog. The original article can be found here. ——————————————————————————————————————————————————— The Grad Guru : Karthik Abinav at University of Maryland, College Park Note : Whenever I mean grad school, I am going to be referring to a PhD program. Though most of this advice also applies to MS programs, you should bear in mind that my focus is on PhD program. Since, I do not have much knowledge about the MS programs, I will not comment much about them in this article. 1. Please tell us about yourself, the university you are studying at, the research field you are working on, and the scope it has to offer after an MS or PhD. Also tell us about a typical day in the life of a postgraduate student. I recently started my PhD in Computer Science at University of Maryland at College Park. I am broadly interested in theoretical computer science. At a high level, … -
Installation of PhoneGap on Debian system
I have recently been developing an application for IOS using phonegap. I was extremely fascinated by the simplicity of its usage. In this post, I will guide through a step-by-step procedure to setup phone gap on a Debian system. Setting Up PhoneGap application on a local system You will come across the term Cordova often when one talks about PhoneGap. Please note that for most purposes, both are essentially interchangeable. Here, I will give instructions to setup cordova on a Linux Debian system. You can make appropriate modifications for your operating system. The first step is to install the latest version of cordova on your system. The installation using the Command-Line Interface is extremely straight forward. 1) Install NodeJS on your system from their website. 2) Run the following to install cordova sudo npm install -g cordova 3) Once cordova is installed, now create a new project. To do that run the following command sudo cordova create photoFilter com.photoFilter.filter photoFilter Note: I am calling my example application as photoFilter. This will create folder called photoFilter in the current directory. The important files to note here are the config.xml file and the www folder. The config.xml file is where you will … -
Mercurial Mirror For Django 1.8 Branch
Another year, another alpha release for Django and … another “production” mirror for me and anybody else interested. Django has just released the first alpha for Django-1.8. As usual, I create the mirror as soon as the corresponding branch is opened (stable/1.8.x), but this is still alpha stuff for you to test, not anything stable you […] -
Importing your old comments to Disqus site
In one of my latest blogpost on disqus I covered topics on integrating Disqus to the website and disqus SSO. In this post, I will let you know how to migrate the older comments to Disqus. If you sneak peek in to the alluring features of disqus you may make your mind to migrate your custom commenting system on your blog to use disqus commenting system. The threaded comments and replies, powerful moderation and admin tools, RSS options and many more features come in as battaries included with Disqus which makes the commenting more interactive and easy to deal with. Let us kick start the process. Till date importing the old comments directly from the blogger and wordpress to disqus is feasible. This can be achieved by using tools and plugins that are already existing in them and its pretty straight forward. In this post our prime concern will be laid on custom XML import format. If you are using neither blogger, nor wordpress the custom XML import format which is based on the WXR (WordPress eXtended RSS) schema comes to the rescue. Disqus also supports MovableType, and IntenseDebate but preferably WXR is of more concern. I consider a case … -
SSL broken in gevent on Python 2.7.9 – a debugging tale of woe
I thought it would be worth writing this up quickly as a blog post, just so it’s documented, though I’m guessing the bug is common knowledge by now. The process of finding out the issue was (eventually) enlightening for me though, especially how far the initial problem was from the bug. I was having problems last week deploying changes to one of our projects hosted on Heroku. I’d done a full run-down of dependencies trying to bring in security and bug fixes, making everything Python 2.7 and Ubuntu Trusty compatible (or, for Heroku, cedar-14 stack compatible). Everything worked fine locally, even using foreman (which is the Heroku tool that runs your code as if it was deployed on Heroku—in this case running through gunicorn with gevent). However, on deploying to a clean app and database on Heroku, the Persona Single-Sign-On authentication wasn’t working. The project’s settings are slightly involved, but the fact the admin site was working and I was getting a login page at all indicated that things were probably okay on the Django side of things. Persona itself worked fine locally, as well as on stage and production deployments on Heroku. I suspected DNS issues, but this turned …
