  • Dr. Robert Ballard: Special Guest at Java Strategy Keynote Sunday

    - by Tori Wieldt
    Dr. Robert Ballard, famed explorer who found the Titanic at its final resting place, will be at the Java Strategy Keynote on Sunday. Among the most accomplished and well known of the world's deep-sea explorers, Dr. Ballard is best known for his historic discoveries of hydrothermal vents, the sunken R.M.S. Titanic, the German battleship Bismarck, and numerous other contemporary and ancient shipwrecks around the world. During his long career he has conducted more than 120 deep-sea expeditions using the latest in exploration technology, and he is a pioneer in the early use of deep-diving submarines. You can learn more about Dr. Ballard and undersea exploration at National Geographic and TED. The first 1,000 people to arrive at the JavaOne Keynote hall on Sunday will receive a copy of Dr. Ballard's TV show "The Alien Deep" on Blu-Ray. The Alien Deep explores the sea, thousands of feet beneath the surface, far from the first crack of light, where the planet’s last and greatest secrets hide in the cold darkness of endless night. Viewers get to see underwater worlds via submersible where no one has gone before. The JavaOne Strategy Keynote is on Sunday at 4:00pm PT at Masonic Auditorium, 1111 California Street. See you there!

  • 12.04 No Sound - ALC888 / Radeon 3200HD

    - by Ross
    Evening all. I have a MSI U230 netbook, MV40 processor, 4Gb RAM with integrated ATI Radeon 3200HD grahics & an ALC888 codec integrated soundcard. It has HDMI out as well. I've tried a few distro's and have been around linux for a short time. I reckon I've settled on Ubuntu 12.04 (32bit) due to it doing pretty much everything I want it to. I'm working with a fresh install right now. I recently re-installed when I was going in circles trying to solve my problem before. I install Ubuntu and it works, except for the sound. I have tried things like reinstalling Alsa, editing my asound.conf file, installing HDA Verb and a few other things. Its at the point where I need to ask for help... Some outputs: ross@ross:~$ aplay -l ** List of PLAYBACK Hardware Devices ** card 0: SB [HDA ATI SB], device 0: ALC888 Analog [ALC888 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 ross@ross:~$ uname -r 3.2.0-34-generic-pae ross@ross:~$ lspci | grep VGA 01:05.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RS780M/RS780MN [Mobility Radeon HD 3200 Graphics] ross@ross:~$ lspci | grep Audio 00:14.2 Audio device: Advanced Micro Devices [AMD] nee ATI SBx00 Azalia (Intel HDA) 01:05.1 Audio device: Advanced Micro Devices [AMD] nee ATI RS780 HDMI Audio [Radeon HD 3000-3300 Series] Added options snd-hda-intel position_fix=1 to alsa-base.conf file Unmuted all in alsamixer Can anyone suggest anything more?

  • "Agile Principles, Patterns, and Practices in C#": Is this just a .NET-translation of the popular Uncle Bob book?

    - by Louis Rhys
    I found this book sold on Amazon Agile Principles, Patterns, and Practices in C#, written by Robert C Martin and Micah Martin. Is it merely a .NET port of the older, more popular Agile Software Development, Principles, Patterns, and Practices? Or is it just a new book trying to take advantage of the other book's popularity? If I am a .NET developer who hasn't read either book, which one would you recommend?

  • Sourcecode for Paymentroll example in Robert C. Martin book

    - by bitbonk
    Throughout the book "Agile Principles, Patterns, and Practices in C#" by Robert C. Martin a small Paymentroll application is build. While most of the source code is printed in place, some classes are missing and some are incomplete. The book says on the firest page: The book includes many source code examples that are also available for download from the authors' Web site. Unfortunately this seems to be a lie. Unless either this is not the author's website (the book forgets to mention the authors website adress) or I am blind. Does anyone have the comlete source code for that book preferably in form of a Visual Studio project or knows where I can find it.

  • Question About Example In Robert C Martin's _Clean Code_

    - by Jonah
    This is a question about the concept of a function doing only one thing. It won't make sense without some relevant passages for context, so I'll quote them here. They appear on pgs 37-38: To say this differently, we want to be able to read the program as though it were a set of TO paragraphs, each of which is describing the current level of abstraction and referencing subsequent TO paragraphs at the next level down. To include the setups and teardowns, we include setups, then we include the test page content, and then we include the teardowns. To include the setups, we include the suite setup if this is a suite, then we include the regular setup. It turns out to be very dif?cult for programmers to learn to follow this rule and write functions that stay at a single level of abstraction. But learning this trick is also very important. It is the key to keeping functions short and making sure they do “one thing.” Making the code read like a top-down set of TO paragraphs is an effective technique for keeping the abstraction level consistent. He then gives the following example of poor code: public Money calculatePay(Employee e) throws InvalidEmployeeType { switch (e.type) { case COMMISSIONED: return calculateCommissionedPay(e); case HOURLY: return calculateHourlyPay(e); case SALARIED: return calculateSalariedPay(e); default: throw new InvalidEmployeeType(e.type); } } and explains the problems with it as follows: There are several problems with this function. First, it’s large, and when new employee types are added, it will grow. Second, it very clearly does more than one thing. Third, it violates the Single Responsibility Principle7 (SRP) because there is more than one reason for it to change. Fourth, it violates the Open Closed Principle8 (OCP) because it must change whenever new types are added. Now my questions. To begin, it's clear to me how it violates the OCP, and it's clear to me that this alone makes it poor design. However, I am trying to understand each principle, and it's not clear to me how SRP applies. Specifically, the only reason I can imagine for this method to change is the addition of new employee types. There is only one "axis of change." If details of the calculation needed to change, this would only affect the submethods like "calculateHourlyPay()" Also, while in one sense it is obviously doing 3 things, those three things are all at the same level of abstraction, and can all be put into a TO paragraph no different from the example one: TO calculate pay for an employee, we calculate commissioned pay if the employee is commissioned, hourly pay if he is hourly, etc. So aside from its violation of the OCP, this code seems to conform to Martin's other requirements of clean code, even though he's arguing it does not. Can someone please explain what I am missing? Thanks.

    - by dmccollough
    The Tulsa SharePoint Interest Group set a record for attendance last night at our SharePoint 2010 Mini-Launch Event. Approximately 40+ people showed up to listen to SharePoint MVP Eric Shupps, The SharePoint Cowboy to discuss all of the new features for both administrators and developers. All of the Tulsa SharePoint Interest Group Officers worked very hard to ensure that this event happened. We hosted our event at our local Dave & Busters and it was a great location with good food and great service. All of the officers of the Tulsa SharePoint Interest Group would like to extend a big Thank You to all of our sponsor that helped us in making our SharePoint 2010 Mini-Launch Event a reality.

  • Why don't I have write permission to my vmware virtual network device?

    - by Robert Martin
    I want to allow my VMWare machine to force the virtual network it's on into promiscuous mode so I can play around with honeyd. I received an error message that told me to go to http://vmware.com/info?id=161 to allow this behavior. Based on their advice, I did: $ groupadd promiscuous $ cat /etc/group | grep promiscuous promiscuous:x:1002:robert $ usermod -a -G promiscuous robert $ id robert uid=1000(robert) gid=1000(robert) groups=1000(robert),....,1002(promiscuous) $ chgrp newgroup /dev/vmnet8 $ chmod g+rw /dev/vmnet8 $ ls -l /dev/vmnet8 crw-rw---- 1 root promiscuous 119, 8 2012-03-29 10:29 /dev/vmnet8 Looks like I gave RW permission to the promiscuous group, and added myself. Except that VMWare still gives me an error message that says I cannot enter promiscuous mode. To try out the group thing, I tried: $ echo "1" >/dev/vmnet8 bash: /dev/vmnet8: Permission denied That really surprised me: It makes me think that I still haven't properly given myself the correct permissions... What am I missing?

  • Spawn a multi-threaded Java program from a Windows command line program, spawner won't end until spa

    - by Ross Patterson
    Short version: How can I prevent a spawned Java process in Windows from blocking the spawning process from ending? Long version: I'm trying to spawn a multi-threaded Java program (Selenium RC, not that it should matter) from a program launched from the Windows command line (NAnt's <exec> task, again, not that it should matter). I'm doing it using the Windows "start" command, and the spawned process is started and runs correctly. The spawning process receives control back and finishes (NAnt says "BUILD SUCCEEDED"), but doesn't actually exit to the command line. When the spawned process finally terminates (could be hours later), the command process returns and the command line prompt occurs. For example: <target name="start_rc"> <exec program="cmd" failonerror="false" workingdir="${ross.p5.dir}\Tools\selenium\selenium-server-1.0.1" verbose="true"> <arg value="/C"/> <arg value="start"/> <arg value="java"/> <arg value="-jar"/> <arg path="${ross.p5.dir}\Tools\selenium\selenium-server-1.0.1\selenium-server.jar"/> <arg value="-userExtensions"/> <arg path="${ross.p5.dir}\Tools\selenium\selenium-server-1.0.1\user-extensions.js"/> <arg value="-browserSideLog"/> <arg value="-log"/> <arg value="${ross.p5.dir}\artifacts\selenium.log"/> <arg value="-debug"/> </exec> </target> Produces: C :\Ross>nant start_rc NAnt 0.86 (Build 0.86.2898.0; beta1; 12/8/2007) Copyright (C) 2001-2007 Gerry Shaw http://nant.sourceforge.net Buildfile: file:///C:/Ross/ross.build Target framework: Microsoft .NET Framework 3.5 Target(s) specified: start_rc start_rc: [exec] Starting 'cmd (/C start java -jar C:\p5\Tools\selenium\selenium-server-1.0.1\selenium-server.jar -userExtensions C:\p5\Tools\selenium\selenium-server-1.0.1\user-extensions.js -browserSideLog -log C:\p5\artifacts\selenium.log -debug)' in 'C:\p5\Tools\selenium\selenium-server-1.0.1' BUILD SUCCEEDED Total time: 4.1 seconds. ... and then nothing until I close the window where Java is running, then ... C:\Ross> Obviously something is preventing the nant process from terminating, but shouldn't the Windows START command prevent that?

  • Macports sudo expands ~ to /var/root in python

    - by calavera
    This might be a bit dev-heavy for the site... but here goes. I installed the macports version of sudo. All is well, except for one thing. Using python 2.6 to expand ~ to the user's home directory results in a different output than the version of sudo that comes with Snow Leopard. For example consider the following python code: #expand_home_dir.py import os os.path.expanduser('~') Below are 3 different calls of the code listed above. The first call using sudo is using the Macports version because my $PATH begins with /opt/local/bin: robert$ python2.6 expand_home_dir.py /Users/robert robert$ sudo python2.6 expand_home_dir.py /var/root robert$ /usr/bin/sudo python2.6 expand_home_dir.py /Users/robert Any idea why this is happening?

  • How do I express subtle relationships in my data?

    - by Chuck H
    "A" is related to "B" and "C". How do I show that "B" and "C" might, by this context, be related as well? Example: Here are a few headlines about a recent Broadway play: 1 - David Mamet's Glengarry Glen Ross, Starring Al Pacino, Opens on Broadway 2 - Al Pacino in 'Glengarry Glen Ross': What did the critics think? 3 - Al Pacino earns lackluster reviews for Broadway turn 4 - Theater Review: Glengarry Glen Ross Is Selling Its Stars Hard 5 - Glengarry Glen Ross; Hey, Who Killed the Klieg Lights? Problem: Running a fuzzy-string match over these records will establish some relationships, but not others, even though a human reader could pick them out from context in much larger datasets. How do I find the relationship that suggests #3 is related to #4? Both of them can be easily connected to #1, but not to each other. Is there a (Googlable) name for this kind of data or structure? What kind of algorithm am I looking for? Goal: Given 1,000 headlines, a system that automatically suggests that these 5 items are all probably about the same thing. To be honest, it's been so long since I've programmed I'm at a loss how to properly articulate this problem. (I don't know what I don't know, if that makes sense). This is a personal project and I'm writing it in Python. Thanks in advance for any help, advice, and pointers!

  • Why the “Toilet” Analogy for SQL might be bad

    - by Jonathan Kehayias
    Robert Davis(blog/twitter) recently blogged The Toilet Analogy … or Why I Never Recommend Increasing Worker Threads , in which he uses an analogy for why increasing the value for the ‘max worker threads’ sp_configure option can be bad inside of SQL Server.  While I can’t make an argument against Robert’s assertion that increasing worker threads may not improve performance, I can make an argument against his suggestion that, simply increasing the number of logical processors, for example from...(read more)

  • Easy Listening = CRM On Demand Podcasts

    - by Anne
    OK, here's my NEW favorite resource for CRM On Demand info -- podcasts! Specifically, the CRM On Demand Podcast site -- signed, sealed, and delivered with humor and know-how. Yes, I admit, I know the cast of characters. But let's face it, sometimes dealing with software is just soooo dry! Not so when discussed by the two main commentators, Louis Peters and Robert Davidson, whom someone once referred to as CRM On Demand's "Click and Clack." (Thought that was too good not to pass along!) Anyhow, another huge plus about the site is the option to listen OR to read. Out walking my dog or doing the dishes? Just turn up the podcast. Listening to music or watching TV? I'll read Louis's entertaining write-ups to glean great info about CRM On Demand in a very short period of time. So that you get a better understanding of why I like this site so much, here's a sampling of what's discussed: Five Things about Books of Business As Louis Peters put it in his entry, when you see "Five Things" in the title, "you'll know you're going to get some concrete advice that you can put to work right away." Well, Louis and Robert do just that, pointing you in the right direction when using Books of Business to segment data. Moving to Indexed Fields - A Rough Guide (only an article, not a podcast) I've read all about performance and even helped develop material around it. But nowhere have I heard indexed custom fields referred to as "super heroes." Louis and Robert use imaginative language to describe the process for moving your data to indexed fields for optimal performance. Data Access QA from the Forums I think that everyone would admit that data access and visibility is the most difficult topic to understand in CRM On Demand. Following up on their previous podcast on the same topic, Louis and Robert answer a few key questions from the many postings on the Oracle CRM On Demand forums. And I bet that the scenarios match many companies' business requirements...maybe even yours! We Need to Talk About Adoption Another expert, Tim Koehler, joins Louis to talk about how to drive user adoption: aligning product usage with business results, communicating why and how to use the product, getting feedback on usability, and so on. Hope I've made my point -- turn to these podcasts to hear knowledgeable folks discuss CRM On Demand tips and tricks in entertaining ways. One podcast is even called "SaaS Talk"!

  • Gateway IP Returns to Zero

    - by Robert Smith
    When you set a static IP under Ubuntu 12.04.1, you must supply the desired machine IP and the gateway IP, all using the Network Manager. When I first entered them and rebooted, everything worked great. On the second boot, however, Firefox could find no Web page. Upon checking, I discovered that the gateway IP had returned to zero. Now, no matter how often I resupply it, it returns to zero immediately after NM "saves" it: that is, appears as zero when redisplayed. The only way I can get to the Internet is to restore DHCP operation. I need to use static IP for access to my home network. Would appreciate any suggestion. --Robert Smith
