  • Chrome's Unsafe Ports

    So apparently Chrome maintains a list of "unsafe" ports (or maybe a list of safe ones). I did not know this... and got a minor headache from it.

    I was trying to setup a new printer remotely on one of my workstations that currently is configured to allow access to CUPS only locally on port 631 (default setup). That's easy enough, I'll just use SSH's port forwarding to allow my connection to appear local to cups:

  • Denyhosts 2.6 (< 6.el5) Misses a Large Number of Attacks

    UPDATE (2015/03/09)

    There was a release of denyhosts that finally fixes this bug! (Maybe the RHEL EPEL maintenance crew read my blog post, haha). So as long as you patch through 2.6-6.el5 (or equivalent if you are running a newer version of CentOS/RHEL/etc) then you will not have this issue. Thanks EPEL team!

    So, I hesitate to call this a vulnerability, but it definitely is a critical issue.

  • Cordova Development (don't forget your cordova.js script tag!)

    Recently we have begun to create a few projects using Apache Cordova. It is a great system that has come a long way from the last time I looked into using it (when it was still "PhoneGap"). It allows you to create a cross-platform mobile app using HTML/CSS/JS, which is great for us as we have plenty of experience using web technologies. There are some limitations as to what native APIs are supported but overall there is a ton that you can do!

  • Blog post on Iowa JPEC

    We have worked with the University of Iowa John Pappajohn Entrepreneurial Center (JPEC) since the very beginning of Bio::Neos. In fact, as a group of 6 engineers with zero practical experience running a business, there was little chance we would still be around 10 years later without their continued support and mentorship. So when I was asked to fill a survey out for their blog, I didn't hesitate to help! Here is the article they put together:

  • Community Outreach

    Here at Bio::Neos we believe in encouraging increased software development related education opportunities for K-12 school level children. Even though additional structured in-person programs are ideal because of the benefits of face-to-face communication in educational programs, there are a ton of free resources online that really make the barriers to learning how to code extremely low. This is important for many reasons, and we are not the only ones believe that to be true.

  • Iowa Homecoming Grand Marshal

    Buddy Lazier came to The University of Iowa this fall to serve at this year's homecoming parade grand marshal and look at what he brought with him:

  • Interesting article on Artificial Sweeteners

    I recently came across an interesting article on the effect that artificial sweeteners have on the human body. Many people, myself included, reach for a diet soda instead of a regular for supposed dietary reasons; for the taste; or simply out of habit. Considering the possible link this study has found between artificial sweeteners and glucose intolerance leading to dysbiosis, I plan to (as the article suggests) reassess my intake of these sweeteners and hopefully even cut them from my diet entirely.

  • Faux Full Width Sections (CSS)

    A relevant design trend on the web is the long scroller. Long scrollers are pages with content organized vertically, typically broken into full width sections designated by visually different backgrounds (color or images). This format supports the easiest and most ergonomic movement on a mobile device, the swipe. It works equally as well on a laptop with a touchpad, or desktop with a mouse that has a decent scrollwheel.
