Semiotics, or the study of symbols and sign processes and meaningful communication, has recently been on my radar because of a class I’m teaching.
Earlier this morning I stumbled on a postÂ by Caitlin Winner on how she pushed forward with a small but meaningful change with the Facebook icon set used to display the now universally recognized Facebook Friends icon.
I shared my complaint with a designer friend and she helpfully pointed me to the poster next to mine which proclaimed, â€œNothing at Facebook is someone elseâ€™s problem.â€ The lady icon needed a shoulder, so I drew it inâ€Šâ€”â€Šand so began my many month descent into the rabbit hole of icon design.
It turns out that others at Facebook have pursued similar changes. For e.g., the globe.
It turns out this kind of self initiated project is not unique at Facebook. Last year, designer Julyanne Liang worked with engineer Brian Jew to give the non-American half of the globe an accurate world view from the notification icon. Since then they’ve added an Asia-centric globe, too.
Symbols are important. The context in which they are used, the global recognition for certain symbols and the misuse of symbols shape our daily interactions.Â More importantly,Â this write up is a great example of how taking personal responsibility and ownership for changingÂ things that seem small to some, but when implemented make a world of difference to others.

Youâ€™ve probably heard of the genetic testing site, 23andMe. The site allows users to send in a swab covered in their saliva for genetic decoding. When that code is translated, itâ€™s viewable online as a pie chart of ancestry. 23andMe even offers an API that allows you to share your genetic information with the REST of the world.Â Genetic information is some powerful stuff: It can countermand information thatâ€™s been passed down through a family, provide a clue to lost relatives, and even offer unexpected insights into oneâ€™s origins. But did you ever think that genetic information could be used as an access control?Â Stumbling around GitHub, I came across this bit of code: Genetic Access Control. Now, budding young racist coders can check out your 23andMe page before they allow you into their website!Â Seriously, this code uses the 23andMe API to pull genetic info, then runs access control on the user based on the results. Just why you decide not to let someone into your site is up to you, but it can be based on any aspect of the 23andMe API.Â This is literally the code to automate racism. The author offers up a number of possible uses, many of which sound fairly legitimate, however. Imagine a womenâ€™s support group online that restricts access to women only. What if JDate didnâ€™t just take your word for it that you were Jewish, and actually checked your DNA to make sure?

Varonis has published a list of introductory web security videos at Web Security Fundamentals.
The main difference between HOTP and TOTP is that the HOTP passwords can be valid for an unknown amount of time, while the TOTP passwords keep on changing and are only valid for a short window in time. Because of this difference generally speaking the TOTP is considered as a more secure One-Time Password solution.
