LarsW@Blogspot: August 2009

http://larswestergren.blogspot.com/2009_08_01_archive.html

Monday, August 10, 2009. I read Chad Fowler's The Passionate Programmer this weekend. All in all a pretty good book which I recommend. Remaining from the previous edition however is one of my least favorite paragraphs in the book. In his essay "Great Hackers", Paul Graham annoyed the industry with the assertion that Java programmers aren't as smart as Python programmers. He made a lot of stupid Java programmers mad (did I say that? Subscribe to: Posts (Atom). View my complete profile.

Wednesday, May 14, 2008. I have been wondering about one thing and throw out this question just in case someone possibly reads my blog - does type inference bring any benefits apart from less typing? I know proponents of dynamic typing consider declaring variable types "noise" because it is the antithesis of their style of coding, and they say the compiler can usually infer the type for you anyway. Scala for instance is designed this way:. Var x = "Hello". Map Integer, Office offMap = .

LarsW@Blogspot: "That" Java example and preaching to the converted

http://larswestergren.blogspot.com/2008/08/that-java-example-and-preaching-to.html

Wednesday, December 23, 2009. That" Java example and preaching to the converted. There is one example of Java code that keeps coming up. I have seen variants of it at conference presentations several times, in Venkat Subramaniam's Programming Groovy. And most recently in an essay by Neal Ford in The ThoughtWorks Anthology. This example compares Java with a scripting language, and goes usually something like this (here I combine all the worst practices from the books in one example):. String line = null;.

Sunday, May 3, 2009. Notes on dataflow concurrency. At a conference, I heard someone say something to the effect of: "Declarative dataflow concurrency is awesome. You can't get deadlocks! It all just works, and it is so beautiful". It is pretty neat, but I thought to myself - "Hang on, if we have two threads that each wait for the other to assign a variable, won't we get a circular dependency between them? Or if there is just one executing thread, won't that block forever? Thread X=Y 1 end. And indeed th...

Tuesday, March 23, 2010. Load log4j.properties from jar file in webapp. Having environment specific log4j.properties inside a jar file is hardly an ideal solution, but if you find yourself in a similar situation:. Import java.net.URL;. Import org.apache.log4j.PropertyConfigurator;. Import javax.servlet.http.HttpServlet;. Public class Log4jConfLoad extends HttpServlet {. Public void init() {. String prefix = jar:file: getServletContext().getRealPath(/);. String path = WEB-INF/lib/the.jar!

LarsW@Blogspot: Simple SOAP client

http://larswestergren.blogspot.com/2011/04/simple-soap-client.html

Friday, April 15, 2011. I needed a quick and simple SOAP client to verify some odd return values from a web service. I also wanted the client to be able to send and receive badly formatted XML for testing purposes, and preferably pretty print the xml. Didn't feel very appealing to try to do this in Java, so I decided to do it with JRuby. Your soapy stuff goes here *. Header = {'Content-Type' = 'application/soap xml'}. Endpoint = http:/ localhost:8080/testService. Client = HTTPClient.new. Dan Bergh Johnss...

Monday, December 8, 2008. Questions to ask employers. After thoroughly grilling the applicant for a job/project, many interviews often end with the question - "So, do you have any questions for us? I've read in articles by career coaches that it is a good idea to have a few questions to ask here - it shows that you are interested. But the first times I had problems coming up with any sincere and interesting questions. Do you use a version control system for your code? Do you have an internal Wiki? Does a...

Tuesday, April 22, 2008. Mobilt bredband med Kubuntu Linux, Tre och Huawei E220. Enklaste sättet att få mobilt bredband från 3 med Huawei E220 ("ovala pucken") att fungera under Kubuntu Linux:. Ladda ner och installera Vodafone Mobile Connect Card driver. Om du stavat fel någonstans i de tre fälten ovan måste du radera profilen och skapa en ny, eftersom en bugg (i alla fall i Beta 2 versionen som jag använder) gör att ändringar gjorda i "edit" mode inte sparas korrekt. Klienten fungerar även bra efter up...

The combination of the two creates very readable error messages and tests that can be quickly and cleanly written by combining predicating matchers. At the end of the session we did a quick recap of what we had learned for the other group. As people came up with new topic ideas, new sticky notes went up on the board during the day. I am a co...
