Limit Up Limit Down Calculator in Beta

Luldcalc is an iOS app I wrote to calculate price bands in accordance to the rules put forth by the LULD Committee: http://www.luldplan.com/index.html

In addition to being a basic calculator, there are buttons to select tier 1 or tier 2 stocks, and also buttons to double the bands for market open and close.

For Testers

A public beta is now available at:

https://testflight.apple.com/join/gWOth57S

The link will introduce you to Apple's TestFlight app which is used to gain access to the beta version of LuldCalc.  You'll need an iPhone running iOS 8 or later.

Install the TestFlight app and you'll find an icon that looks like this:

Open the TestFlight app, and you will be presented with a screen to redeem LuldCalc:

Redeem to use LuldCalc


Have fun and let me know your thoughts.

Bookshelf: UNIX A History and a Memoir

  A man page will give you, in black and white, specific information about UNIX. Brian Kernighan's new book adds color and depth about UNIX you won't find anywhere else. I'm not a gray beard (yet), but I imagine they would plow through the book knowingly, but at the same time, learn a few things. Those new to UNIX -- recent college grads or those experimenting with Raspberry Pi -- would be better off starting with Chapter 8 which describes more relatable events and the descendants of UNIX, including Minux and Linux. It's when they start to ask questions like "Where does UNIX come from?" and "Why is Gamora grep?" that they should start from the beginning: Bell Labs, 1969. Kernighan opens with a birds-eye-view of Murray Hill New Jersey, zooms in on the buildings, the offices, the significance of Center 1127, and offers a brief look at some of the key players there. As I progressed through the book, the two factors that made UNIX not just possible, bu

Bookshelf Classic: The C Programming Language

My first job had me programming in Microsoft BASIC for the IBM PC (DOS).  BASIC worked well enough, but its limitations were clear.  The language was interpreted and therefore slow.  More importantly, it wasn't a modern structured language, and instead, relied on line numbers and the GOTO statement.  Anyone who has read Dijkstra knew  GOTO was a bad thing . Having learned a structured language in college ( PL/I ), using BASIC felt unnatural.  When a C compiler became available for the PC, I saw a chance to improve and modernize our software.  The problem was selling the idea -- a problem made harder because I wasn't fluent in C. "It would be a staffing problem.  Not many people know C, but we can find a lot of programmers who know BASIC," noted one manager. The argument was strong as my knowledge of C was weak.  But I knew that C, by design, was a small language and thus easy to learn.  "It has about 30 keywords," I proffered to another manager. U

Opening a drawer in my hotel room in Toronto, I found this.  I worship at the altar of tech, but I imagine the reaction between two priests might go like this: Mormon Priest:  "At least we're wireless!" Catholic Priest: "And from the very beginning too!"
