| The Latest from Handwaving | MORE | | Ubuntu is too much work It looked good, it appeared to work and all was well. Unfortunately, my laptop has a switch to manually choose between Intel’s integrated graphics and an Nvidia GPU. It took tons of searching to gather clues from cryptic emails and blogs to learn that it probably doesn’t work on Linux 3.2 It took a lot of searching to figure out how to load the right drivers and get unity-3D. The problem with Ubuntu, and Linux in general, is that it always requires some magical incantation to make things work. for some reason. Maybe. DevelopMentor Courses - Thursday, May 17, 2012 Weather Prediction Error I wrote a Python script to download the 1 through 5 day predictions for the weather in the top 50 American cities from the Weather Underground. put the data up here , but I don’t yet know how to add visualizations. In addition to the temperature, I stored things like weather condition (rain, snow, cloudy, etc) which may help make better predictions. ve got almost 2 years of data now. Here are the RMSE for predictions for all cities. believe the RMSE for all cities is 2.24, 2.89, 3.68, 4.29, 4.92 degrees F for 1 through 5 days respectively. Miscellaneous DevelopMentor Courses - Friday, December 30, 2011 Google Interview Prompted by a recruiter, I submitted a resume to Google. So he asked me to implement a hash function. thought he wanted to know the odds of collisions using XOR as a hash. The whole interview went like this, including how to implement a hashtable. They let me skip the phone screen and just do the full-day interview with 5 guys. It was easier than I feared. If you can do the first half of CLR you should be fine, except for trick questions. Unfortunately, I think I blew my last interview. He posed a simple problem: Given a lot of files, find all the duplicates.

The issue is how to map the performance of real programs to a new language using data from simple benchmarks. How would my Java program perform if written in Haskell? People seem to have given up on this sort of comparison, but I think it’s possible to generate a decent approximation. The first step is to break down the performance of a real program using detailed profiling data. suite of micro-benchmarks that exercise these low-level operations can be used to map between languages. The remaining time is the real cost of the PL. Handwaving - Wednesday, May 26, 2010 - Explaining OpenID
I was setting up OpenID for a Drupal site and realized that nobody is going to know how to use it. goes to OpenID’s home page , which greets customers with a Big Wall of Text that nowhere explains what to put in the little OpenID text box. that suggested that non-tech users have no clue what OpenID is or how to use it. This is yet another example of tech people not knowing how to communicate to those outside their tiny circle. They are bound to break into many accounts. The link “What is OpenID?” Handwaving - Friday, March 26, 2010 - The Financial Crisis
money market fund (MMF) has $1B in cash and no safe place to deposit it. But the MMF wants to be able to withdraw money at anytime, so the bank agrees to buy back those bonds the very next day. From the bank’s point of view, the repo market turns their vast holding of Aaa bonds (required for all sorts of purposes) into cash they can use to do more lucrative investments. The repo market got super huge and there wasn’t enough high quality bonds to meet demand. Somehow the banking system must be made more resilient to panics. Handwaving - Friday, March 5, 2010 - A few problems installing Windows 7
I installed Windows 7 64-bit on my desktop and was forced to overcome a few problems. It took a great deal of searching to find the solutions, so I’m detailing it here to help others. The first lesson is never use the Windows tools to upgrade the BIOS. had to send for a replacement motherboard from ASUS (they responded quickly and without any hassles). The solution here is to turn on the “Memory Remap Feature” under Advanced->North Bridge Configuration in the BIOS. It turns out you need to turn on AHCI in the BIOS. Handwaving - Thursday, January 7, 2010 - Spelling Corrector in Factor
A while ago, Peter Norvig posted a lucid explanation of how to write a spelling corrector. He did it in an impressive 21 lines of readable Python code. Here is my attempt at the same spelling corrector using the Factor programming language. It’s 19 lines if you don’t count the unusually verbose USING statement at the top. Handwaving - Monday, December 14, 2009 - Fixing Health Care
This isn’t a good way to transform a $2 trillion chunk of our economy. For posterity, here’s an outline of how to “fix health care”. First, the cost of the current system is growing so fast it will inevitably force the government, businesses and insurance companies to radically scale back medical services available to most people. So the two problems are cost and access to health care. Increase gov’t R&D to offset corporate R&D expense. Solution: Hospitals need an incentive to become more efficient. and government). Handwaving - Tuesday, October 13, 2009 - Scientific Evaluation of Programming Languages
A new workshop at OOPSLA is aimed at finding ways to evaluate the effectiveness of programming languages and tools. Unfortunately, the entire conference rests on a single problem: how to measure programmer productivity. Except for pointy-haired bosses , most software professionals believe productivity can not be accurately measured. This workshop will likely be yet another outlet for HCI research with awful methodologies. Handwaving - Thursday, August 13, 2009 %>

| The Latest from DevelopMentor | MORE | | Integrating the #WebAPI HttpClient and ApiController in a single test 'In the two previous blog posts I showed how to unit test and ASP.NET WebAPI controller and how to unit test the client side code depending on the HttpClient class. After all testing an ApiController by just calling the methods makes it perfectly possible to call them in such a way that would never be possible using a real HTTP request. So in order to complete out testing we should test the integration of the client and server parts using an integration test. However there we added a custom TestingDelegatingHandler to return a fake result message.

The Problem Solver - Monday, May 27, 2013 Unit testing code depending on the ASP.NET WebApi HttpClient 'In a previous post I showed how to unit test an ASP.NET WebAPI Controller. In this case the client application contains the following class to load books from the REST WebAPI controller: 1: public class BooksClient. This class uses the HttpClient to request the data from the service and extracts the books from the body before returning them. If we want to test this class we need to pass in an HttpClient object. This HttpMessageHandler is used as the pipeline to send requests and we can completely replace this with our own implementation. 14: {. Maurice de Bejeir - Monday, May 20, 2013 | -
| The Best from DevelopMentor | MORE | - How to improve a team's velocity?
By way of wrapping up my velocity mini-series ( Two ways to fill and iteration , Filling an iteration too well , and Velocity Targeting and Velocity Inflation ) I’m going to end with some advice on how to improve a team’s velocity. Over time these add up to big improvements. To use economic logic: this is about improving the supply-side. The supply-side argument (largely monetarist) suggests the way to solve unemployment is not to increase demand (Keynes style) but to loosen and liberalise the labour market. But back to software. Allan Kelly's Blog - Thursday, July 1, 2010 - How to rip audio books
So i listen to a lot of audio books, and here's how i create the mp3 of them. Overview we are going to create bite size files about 30 minutes each. link] 4) set your encoding bitrate to 64k & stereo, this is a very high quality audio book. To do this double click a track. then label them, and create the id tags. finally we'll attach a picture. Make sure the book is UNABRIDGED 1) get a ipod - i prefer the nano. link] Ripping 2) download audiograbber & install. link] 3) download lame encoder & install. select the Sectors>Last.

So I ended up running Windows Cerificate Services which proved to be an easy to use, robust solution. just had to rebuild my Test CA (on Hyper-V) so I thought I'll document the important steps (for self-reference and whoever might be interested). They usually expire on the very day where you have to do an important demo. Now by default there is an entry pointing to the CA's Netbios name. better solution is to create a revocation list once, and store that at a publicly available location. Next you have to publish a CRL. Set it to e.g. five years. www.leastprivilege.com - Thursday, August 14, 2008 - How to get started with Knockout.js
Once you get into doing more client side JavaScript code with business applications and REST services you are going to run into the question of how to construct the client side HTML required to show the data to the users. Using jQuery Assuming most people are going to be using jQuery on the client you might start with some jQuery code to generate HTML. And in all likelihood the actual HTML that needs to be generated will be quite a bit more complex. The next step people tend to take is using templates. click( function () {. $.getJSON( The Problem Solver - Monday, February 6, 2012 - How to discover what font was used
Sometimes you’re working on a website and you get some images with text in them, but no one remembers what fonts was used in the image. No fear! There is a website call “What The Font” that will take your picture and tell you what font was used: [link]. ASP.NET DevelopMentor Courses - Monday, December 26, 2011 %>
