Slides and Samples for My TechEd / Microsoft BI Conference Talks

- by plitwin

I posted the slides and samples for my talks I delivered in New Orleans on June 8th at Microsoft TechEd and Business Intelligence Conference. They can be downloaded from Paul Litwin's Conference Downloads. #1 Creating Report Subscriptions with SQL Server 2008 Reporting Services at 8 AM on Tuesday. Room 241In this session, learn how to set up standard and data-driven subscriptions using Report Manager. We discuss creating file-share, email, and null subscriptions; and how to deal with potential issues with parameters and security. We also demonstrate a sophisticated Microsoft ASP.NET-based application that creates subscriptions by calling the SSRS Web Services API. #2 ASP.NET MVC for Web Forms Programmers at 3:15 PM Tuesday. Room 391Are you comfortable creating ASP.NET Web Form applications but even a little curious about what all the fuss is about MVC and test-driven development? In this session, Web Form junkie Paul Litwin takes a critical look at the world of ASP.NET MVC, but not from any expert point of view. Instead, Paul shares his experience as a Web Form developer who decided to take a closer look at this radical new approach to ASP.NET development. Come hear what Paul learned and if he plans to employ ASP.NET MVC in his future ASP.NET applications.

unable to read/write CIFS mounts in Ubuntu 11.10

- by Paul Collins

upgraded my laptop from 11.04 too 11.10 and since then the CIFS mounts are not working before the upgrade it would allow mounts on host names, in 11.10 its only IP addresses (not much of an issue) however all the shares i mount are as Read only despite the FStab File declaring the options rw and auto, i have chowned the mount point to be nogroup.nouser and it still wont work, here is an extract from my FSTAB: //192.168.1.1/stories /home/paul/Documents/Stories cifs rw,user,exec,auto,username=,password= 0 0

Hi Sorry if this has been asked many times before I did search and couldnt find anything but perhaps I'm not using the right terminology . I want to install a dual boot, Ubuntu and Windows7 but I want to be able to access my stored files , documents, music, pictures etc from either OS . I already have Ubuntu installed so if there's away without re-installing I am , as you might have guessed new to ubuntu so its all a bit new and strange .

Using Sizer for recording presentations

- by John Paul Cook

I needed to do some screen captures and recordings of SSMS and realized this is a common problem that many of you could use some help with. There is a freeware tool called Sizer (thanks to Paul Nielsen for telling me about it) that lets you chose your window size. I downloaded the zip file instead of the msi because I didn’t want to install anything. The extracted executable works perfectly as a portable application. After double-clicking the Sizer executable, an icon resembling a plus sign appears...(read more)

SQL string formatter

- by Paul D. Eden

Does anyone know of a program, a utility, or some programmatic library, preferably for Linux, that takes an unformatted SQL string and pretty prints it? For example I would like the following select * from users where name = 'Paul' be changed to something like this select * from users where name = 'Paul' The exact formatting is not important. I just need something to take a large SQL string and break it up into something more readable.

Why are so many DBCC commands undocumented?

- by DBA

Paul Randal of SQLskills.com does a great job of answering the question of why there are so many undocumented DBCC commands in his post Why are so many DBCC commands undocumented? I would like to go on to say that not only does this apply to the DBCC commands but is some respect to all parts of SQL, other Servers, IDE's, Operating Systems, just about everywhere. There is always something that just does not make it into the official documentation. And as Paul points out probably never will make it. That could be why there are so many "Tips & Tricks" types of books, blog post, etc. everywhere you look. And I also agree with Janos's comments on Paul's post, which was "I'm fine with them undocumented. All of us who need to use these commands know where to find "documentation" and whom to ask ".

Creating Entity as an aggregation

- by Jamie Dixon

I recently asked about how to separate entities from their behaviour and the main answer linked to this article: http://cowboyprogramming.com/2007/01/05/evolve-your-heirachy/ The ultimate concept written about here is that of: OBJECT AS A PURE AGGREGATION. I'm wondering how I might go about creating game entities as pure aggregation using C#. I've not quite grasped the concept of how this might work yet. (Perhaps the entity is an array of objects implementing a certain interface or base type?) My current thinking still involves having a concrete class for each entity type that then implements the relevant interfaces (IMoveable, ICollectable, ISpeakable etc). How can I go about creating an entity purely as an aggregation without having any concrete type for that entity?

PHP Aspect Oriented Design

- by Devin Dixon

This is a continuation of this Code Review question. What was taken away from that post, and other aspect oriented design is it is hard to debug. To counter that, I implemented the ability to turn tracing of the design patterns on. Turning trace on works like: //This can be added anywhere in the code Run::setAdapterTrace(true); Run::setFilterTrace(true); Run::setObserverTrace(true); //Execute the functon echo Run::goForARun(8); In the actual log with the trace turned on, it outputs like so: adapter 2012-02-12 21:46:19 {"type":"closure","object":"static","call_class":"\/public_html\/examples\/design\/ClosureDesigns.php","class":"Run","method":"goForARun","call_method":"goForARun","trace":"Run::goForARun","start_line":68,"end_line":70} filter 2012-02-12 22:05:15 {"type":"closure","event":"return","object":"static","class":"run_filter","method":"\/home\/prodigyview\/public_html\/examples\/design\/ClosureDesigns.php","trace":"Run::goForARun","start_line":51,"end_line":58} observer 2012-02-12 22:05:15 {"type":"closure","object":"static","class":"run_observer","method":"\/home\/prodigyview\/public_html\/public\/examples\/design\/ClosureDesigns.php","trace":"Run::goForARun","start_line":61,"end_line":63} When the information is broken down, the data translates to: Called by an adapter or filter or observer The function called was a closure The location of the closure Class:method the adapter was implemented on The Trace of where the method was called from Start Line and End Line The code has been proven to work in production environments and features various examples of to implement, so the proof of concept is there. It is not DI and accomplishes things that DI cannot. I wouldn't call the code boilerplate but I would call it bloated. In summary, the weaknesses are bloated code and a learning curve in exchange for aspect oriented functionality. Beyond the normal fear of something new and different, what are other weakness in this implementation of aspect oriented design, if any? PS: More examples of AOP here: https://github.com/ProdigyView/ProdigyView/tree/master/examples/design

Creating the concept of Time

- by Jamie Dixon

So I've reached the point in my exploration of gaming where I'd like to impliment the concept of time into my little demo I've been building. What are some common methodologies for creating the concept of time passing within a game? My thoughts so far: My game loop tendes to spend a fair bit of time sitting around waiting or user input so any time system will likely need to be run in a seperate thread. What I've currently done is create a BackgroundWorker passing in a method that contains a loop triggering every second. This is working fine and I can output information to the console from here etc. Inside this loop I have a DateTime object that is incrimented by 1 minute for every realtime second. (the game begins in the year 01/01/01) Is this a standard way of acheiving this result or are there more tried and tested methods? I'm also curious about how to go about performing time based actions (reducing player energy, moving entities around the game board, life/death etc). Thanks for any pointers or advice. I've searched around however I'm not familiar enough with the terms and so my searches are yeilding little result on this one.

Seperating entities from their actions or behaviours

- by Jamie Dixon

Hi everyone, I'm having a go at creating a very simple text based game and am wondering what the standard design patterns are when it comes to entities (characters, sentient scenery) and the actions those entities can perform. As an example, I have entity that is a 'person' with various properties such as age, gender, height, etc. This 'person' can also perform some actions such as speaking, walking, jumping, flying, etc etc. How would you seperate out the entity from the actions it can perform and what are some common design patterns that solve this kind of problem?

12.04 - Connecting Acer X203H monitor to new Dell XPS 15z laptop

- by Lucy Dixon

I have installed the latest version of Ubuntu (12.04) on my boyfriend's new Dell XPS 15z laptop. He uses a Microsoft wireless keyboard and mouse, and an Acer X203H monitor with his set-up. No problems with the keyboard or mouse, or with connecting the HP printer, but we just can't get the laptop to talk to the Acer monitor. With his old setup he used a VGA cable to connect machine & monitor. New laptop has no VGA port, but we've bought a VGA to HDMI adaptor to connect to the laptop. Have tried using Fn F2 to change the display from laptop to monitor, but it doesn't see the monitor at all. HELP! Is there a driver I can install from somewhere? Or how can I tell Ubuntu to look for the monitor on another port? Completely in the dark, and about to get in trouble!! Thanks

I am trying to round up cases when it makes sense to use a map (set of key-value entries). So far I have five categories (see below). Assuming more exist, what are they? Please limit each answer to one unique category, put up an example, and vote up the fascinating ones. Property values (like a bean) age -> 30 sex -> male loc -> calgary Histograms peter -> 1 john -> 7 paul -> 5 Presence, with O(1) performance peter -> 1 john -> 1 paul -> 1 Functions peter -> treatPeter() john -> dealWithJohn() paul -> managePaul() Conversion peter -> pierre john -> jean paul -> paul

Networking disabled

Both the Wifi and the ethernet connection to the internet are not working. All had been functioning fine until the Ubuntu suspended itself. On re-starting, the connection to internet failed to function and now I get the message "Network Disabled" whenever I re-boot. nm-tool tells me the state is "asleep". Stopping and starting the NetworkManager has no effect The machine is an Inspiron 9300 and work perfectly with Windows. How do I wake the networking up? Thanks

HP 6735s Brightness hotkey problem; where is brightness panel?

- by Paul

I have installed ubuntu 11.10 on my laptop hp 6735s. The screen is often too dark and i want to make it brighter, although the hotkeys Fn+F7/F8 are not working. I have tried some things: Firstly it appears that sometimes they are in fact working, after reboot they either work and continue to do so or they don't. I've read about a brightness applet; but where can i find or install it? I have tried some grub options; acpi_osi=Linux and acpi_backlight=vendor but nothing changes. I don't want to add another question but since it might be related: my laptop also gets quite hot, i'm having doubts whether ubuntu connects to the available sensors and cooling plans (or how does it work???); sensors (or psensor) only shows 2 sensors both named temp1. Any help is greatly appreciated! Paul

SEO Benefits of adding a Tumblr feed to site

- by Paul

A client of ours has a CMS driven Blog in his hotel site - he would like to use the blog to add depth top his site and add seo benefits relating to the blogs content. The current blog is a basic header / text field and doesn't contain any tagging / meta features. Unfortunately we dont have a .net developer in our team to alter the existing blog and add meta / tagging and there isn't budget to hire one - so I considered using a Tumblr blog - setting it up externally - giving it a blog.hotelname.com address and feeding it into the existing page via tumblrs js - which basically does a document.write into the page - which we can style. I understand from a previous post (Poor CMS blog vs Tumblr embed as a general rule most search engines ignore JS created content - but will the above approach act as an improvement on the existing system for now - as the blog will be setup externally with its own url and also feed into the existing site? Cheers Paul

Site inaccessible by some people, fine for others [on hold]

- by Paul Howell

A couple of days ago my website www.howellphoto.com (hosted by one.com, wordpress site) started loading really slowly, and I have been unable to access any pages linked from the homepage. Several of my friends have found the same issue, yet many are able to access the site without problem. Live support at one.com have not been all that much help, requesting the ip addresses of a few people who cannot access the site, and saying it could be a firewall issue. Wordpress support (my site was created in prophotoblogs) have been better and have updated all plugins, etc, but can see no issue from their end. My main issue is that even if there was a local fix that I could do on my computer, this would not help wih any potential customers visiting my site for information! This is driving me crazy!!! Any help will be legendary! Cheers, Paul

C# - Do you use "var"?

- by Paul Stovell

C# 3.0 introduces implicitly typed variables, aka the "var" keyword. var daysInAWeek = 7; var paul = FindPerson("Paul"); var result = null as IPerson; Others have asked about what it does or what the problems with it are: http://stackoverflow.com/questions/527685/anonymous-types-vs-local-variables-when-should-one-be-used http://stackoverflow.com/questions/209199/whats-the-point-of-the-var-keyword http://stackoverflow.com/questions/41479/use-of-var-keyword-in-c I am interested in some numbers - do you use it? If so, how do you use it? I never use var (and I never use anonymous types) I only use var for anonymous types I only use var where the type is obvious I use var all the time!

Have loaded a php variable into flash but cant apply it in a function...

- by Paul Elliot

hi I have created an actionscript function which stops an animation on a specific frame which works fine. I have then loaded in a php file with a variable which will contain the number for the frame i want the animation to stop on. This has loaded in fine and i have loaded it in a function. what i cant seem to do is to get the variable into the function which tells the animation to stop playing. here is my code: //load variables varReceiver = new LoadVars(); // create an object to store the variables varReceiver.load("http://playground.nsdesign6.net/percentage/external.php"); //load variables //function1 varReceiver.onLoad = function() { //value is the var that is created. var paul = this.percentage; } //function1 //function2 this.onEnterFrame = function() { if(this._currentframe==(percentage)) { this.stop(); this.onEnterFrame = undefined; } } play(); //function2 cheers paul

Craftsmanship Tour: Day 3 & 4 8th Light

- by Liam McLennan

Thursday morning the Illinois public transport system came through for me again. I took the Metra train north from Union Station (which was seething with inbound commuters) to Prairie Crossing (Libertyville). At Prairie Crossing I met Paul and Justin from 8th Light and then Justin drove us to the office. The 8th Light office is in an small business park, in a semi-rural area, surrounded by ponds. Upstairs there are two spacious, open areas for developers. At one end of the floor is Doug Bradbury’s walk-and-code station; a treadmill with a desk and computer so that a developer can get exercise at work. At the other end of the floor is a hammock. This irregular office furniture is indicative of the 8th Light philosophy, to pursue excellence without being limited by conventional wisdom. 8th Light have a wall covered in posters, each illustrating one person’s software craftsmanship journey. The posters are a fascinating visualisation of the similarities and differences between each of our progressions. The first thing I did Thursday morning was to create my own poster and add it to the wall. Over two days at 8th Light I did some pairing with the 8th Lighters and we shared thoughts on software development. I am not accustomed to such a progressive and enlightened environment and I found the experience inspirational. At 8th Light TDD, clean code, pairing and kaizen are deeply ingrained in the culture. Friday, during lunch, 8th Light hosted a ‘lunch and learn’ event. Paul Pagel lead us through a coding exercise using micro-pomodori. We worked in pairs, focusing on the pedagogy of pair programming and TDD. After lunch I recorded this interview with Paul Pagel and Justin Martin. We discussed 8th light, craftsmanship, apprenticeships and the limelight framework. Interview with Paul Pagel and Justin Martin My time at Didit, Obtiva and 8th Light has convinced me that I need to give up some of my independence and go back to working in a team. Craftsmen advance their skills by learning from each other, and I can’t do that working at home by myself. The challenge is finding the right team, and becoming a part of it.

Back home :-)

- by Mike Dietrich

Wrote this entry last night in the ICE from Stuttgart to Munich but the conncetion broke: 28.5 hour journey - and close by now. Actually I would have been even closer if our TGV wouldn't have had break problems as soon as we had entered German territory. And you don't want a train which goes up to a speed of 200 mph having issues with its breaks, right? So we missed the connection in Stuttgart but I've catched the last train this night towards Munich. Distance approx 1900 km all together. Usually it takes 2.5 hours with a direct flight with Air Lingus from Munich or a bit more when you'll go through Zurich or Frankfurt. But at least you meet more people and see a bit more from the landscapes passing by :-) Except for the break problem everything worked out well so far (I'm no there finally!). I had 4 hours to change in Paris from Gare de Nord to Gare de l'Est and one thing I really have to point out: the people working for SNCF, the French National Railways, were so organized and helpful, purely amazing. I asked the man at the counter where I had to pick up my prepaid tickets for directions to Gare de l'Est - and after we had a chat about Marlene Dietrich he just grabbed his iPhone, started Google Earth and showed me the way to walk. I pretty sure it's a stupid stereotype that people in Paris or France are so unfriendly to foreigners if they don't speak French. In my past 3 stays or travels to Paris in the past 2 years I had only great experiences. And another thing I really enjoy when being in France: the food!!! The sandwich I had at the train station was packed with yummy goat cheese. And there's always Paul. You might ask yourself: Who the heck is Paul? That's Paul - or actually their website. And at Paul's they serve usually excellent fruit tartes - and this time a nice Gateau Au Chocolate. And very good Cafe Cremé as well :-) That's actually the positive part traveling this way: the food you'll get is much better than the airline food - if your airline still serves something called food ...
