Fortunately, we have both a beginner’s primer on linear algebra and a follow-up primer on inner products. The Quest We are on a quest to write a program which recognizes images of faces.

Update 2023-10-17 The script has been verified to work in macOS Sonoma. When I switched from an older MacBook Pro to a MacBook Air the backup from my old MacBook Pro was corrupted and unmountable. However, I had preserved a backup of my Photo Booth Photos and wanted the Photo Booth application to recognize them. This is just a matter of creating a Recents.plist, an ordered list of the image files. While adding these photos to the Recent....

To find the number of days until the end of the month, compare with the first day of the next month

It’s a common enough problem, you want to find out if a date is in a particular month, or you want to know how many days there are left in the current month, and so on. I’ve seen the following awkward solution plenty of times at different companies: To find out if a day is within a month, you see if the date in question is greater than the start of the month and less than the end of the month; this seems logical enough. To determine the n..

It is now possible to share all public tracks and playlists to the connections of the authenticated user. So if a user is already connected e.g. with Facebook on SoundCloud, this connection can be used from your app to share a track.

Hopefully getting pretty well polished by now. New features and fixes include: Twitter fix - spotted by piaqt and Matthieu Guyonnet-Duluc Tile and Breaking news service fix - spotted by fleon and McFly Long press on feeds for pin and remove on home screen, you may need to clear your current feeds for this to function correctly but didn’t want to force this in case it was unnecessary - suggested by Glenn and fleon Added News ma..

Vector spaces alone are not enough to do a lot of the interesting things we’d like them to do. Since a vector space is a generalization of Euclidean space, it is natural for us to investigate more specific types of vector spaces which are more akin to Euclidean space. In particular, we want to include the notion of a dot product. By admitting additional structure to a vector space, we may perform more computations, and hopefully get more in..

We present a video on Möbius transformations and the geometry of the sphere. Anyone who has taken or will take complex analysis (that means you engineers!) should watch this. It shows not only the beautiful correspondence between the two, but it reveals the intuition behind a lot of complex analysis, when more often than not a student is left in the dust of rigorous formulas. In short, this is a proof without words that the Möbius transform..

I have a confession to make. I am not very consistent with upgrading my software. My iPhone 4 is about 6 months out of date and every time that the little updater came up in Snow Leopard on my MacBook Pro I just waved it off and told it to go away.

Tonight’s the Night” A large volume of research goes into the psychological and behavioral analysis of criminals. In particular, serial criminals hold a special place in the imagination and nightmares of the general public (at least, American public). Those criminals with the opportunity to become serial criminals are logical, cool-tempered, methodical, and, of course, dangerous. They walk among us in crowded city streets, or drive slowly d..

Today we announce a better way to share sounds in SoundCloud via the API. The new interface resembles the way sharing happens on the website. You can retrieve, create, update and delete sharings to other users on SoundCloud based on user_id or email address for your tracks and playlists.

It seems that false proofs are quickly becoming some of the most popular posts on Math ∩ Programming. I have been preparing exciting posts on applications of graph coloring, deck stacking, and serial killers. Unfortunately, each requires resources which exist solely on my home desktop, which is currently dismantled in California while I am on vacation in Costa Rica. Until I return from the tropics, I will continue with more of the ever -pop..

A lot of geeks are using Markdown as their markup generation tool today. It’s simple, effective and used everywhere. It allows you to focus on your content and not on the HTML code that will be used to display the content on a web page. I have used Markdown extensively and its simplicity is appealing to me. reStructuredText is similar to Markdown. If you know Markdown, it’s dead simple to learn to use RST. So, why bother? There are many....

Virtually every Christian has been taught that prayer is when you talk to God with your eyes closed . We tell our children, “Close your eyes and we will pray”. The idea of having your eyes closed when you pray is so engrained in our culture that we don’t give it a second thought. As protestant Christians, we believe that the Bible contains actual words of God. We also believe in the sufficiency of the Bible’s instruction. Let’s survey th....
