  • Stand-Up Desk 2012 Update

    - by BuckWoody
    One of the more popular topics here on my technical blog doesn't have to do with technology, per-se - it's about the choice I made to go to a stand-up desk work environment. If you're interested in the history of those, check here: Stand-Up Desk Part One Stand-Up Desk Part Two I have made some changes and I was asked to post those here.Yes, I'm still standing - I think the experiment has worked well, so I'm continuing to work this way. I've become so used to it that I notice when I sit for a long time. If I'm flying, or driving a long way, or have long meetings, I take breaks to stand up and move around. That being said, I don't stand as much as I did. I started out by standing the entire day - which did not end well. As you can read in my second post, I found that sitting down for a few minutes each hour worked out much better. And over time I would say that I now stand about 70-80% of the day, depending on the day. Some days I don't even notice I'm standing, so I don't sit as often. Other days I find that I really tire quickly - so I sit more often. But in both cases, I stand more than I sit. In the first post you can read about how I used a simple coffee-table from Ikea to elevate my desktop to the right height. I then adjusted the height where I stand by using a small plastic square and some carpet. Over time I found this did not work as well as I'd like. The primary reason is that the front of these are at the same depth - so my knees would hit the desk or table when I sat down. Also, the desk was at a certain height, and I had to adjust, rather than the other way around.  Also, I like a lot of surface area on top of a desk - almost more of a table. Routing cables and wiring was a pain, and of course moving it was out of the question.   So I've changed what I use. I found a perfect solution for what I was looking for - industrial wire shelving: I bought one, built only half of it (for the right height I wanted) and arranged the shelves the way I wanted. I then got a 5'x4' piece of wood from Lowes, and mounted it to where the top was balanced, but had an over-hang  I could get my knees under easily.My wife sewed a piece of fake-leather for the top. This arrangement provides the following benefits: Very strong Rolls easily, wheels can lock to prevent rolling Long, wide shelves Wire-frame allows me to route any kind of wiring and other things all over the desk I plugged in my UPS and ran it's longer power-cable to the wall outlet. I then ran the router's LAN connection along that wire, and covered both with a large insulation sleeve. I then plugged in everything to the UPS, and routed all the wiring. I can now roll the desk almost anywhere in the room so that I can record, look out the window, get closer to or farther away from the door and more. I put a few boxes on the shelves as "drawers" and tidied that part up. Even my printer fits on a shelf. Laser-dog not included - some assembly required In the second post you can read about the bar-stool I purchased from Target for the desk. I cheaped-out on this one, and it proved to be a bad choice. Because I had to raise it so high, and was constantly sitting on it and then standing up, the gas-cylinder in it just gave out. So it became a very short stool that I ended up getting rid of. In the end, this one from Ikea proved to be a better choice: And so this arrangement is working out perfectly. I'm finding myself VERY productive this way. I hope these posts help you if you decide to try working at a stand-up desk. Although I was skeptical at first, I've found it to be a very healthy, easy way to code, design and especially present over a web-cam. It's natural to stand to speak when you're presenting, and it feels more energetic than sitting down to talk to others.

  • It's intellisense for SQL Server

    - by Nick Harrison
    It's intellisense for SQL Server Anyone who has ever worked with me, heard me speak, or read any of writings knows that I am a HUGE fan of Reflector.    By extension,  I am a big fan of Red - Gate   I have recently begun exploring some of their other offerings and came across this jewel. SQL Prompt is a plug in for Visual Studio and SQL Server Management Studio.    It provides several tools to make dealing with SQL a little easier for your friendly neighborhood developer. When you a query window in a database, the plugin kicks in and gathers the metadata for the database that you are in.    As you type a query, you get handy feedback like a list of tables after you type select.    You can select one of the tables, specify * and then tab to expand the select clause to include all of the columns from the selected table.    As you are building up the where clause, you are prompted by the names of columns in the selected tables. If you spend any time writing ad hoc queries or building stored procedures by hand, this can save you substantial time. If you are learning a new data model, this can greatly cut down on your frustration level. The other really cool thing here is Format SQL.   I have searched all over the place for a really good SQL formatter.    Badly formatted  SQL is so much harder to read than well formatted SQL.   Unfortunately, management studio offers no support for keeping your SQL well formatted.    There are many tools available to format your SQL.   Some work better than others.    Some don't work that well at all.   Most will give you some measure of control over how the formatted SQL looks.    SQL Prompt produces good results and is easy to configure. Sadly no tool is perfect, and what would we be without a wish list.    There are some features that I would like to see: Make it easier to paste SQL in and out of code.    Strip off string builder, etc Automate replacing hard coded values with bind variables or parameters In addition to reformatting SQL, which is a huge refactor, support for other SQL refactors would be nice.    Convert join to sub query and vice versa come to mind Wish list a side, this is a wonderful tool that easily saves me an hour or more on most weeks.

  • Boot Problem in Asus EEE PC 1015CX

    - by Sâmrat VikrãmAdityá
    I am a newbie to Linux world, although I have previously worked on Ubuntu 11.04 for daily use (Net Access and simple recordings using Audacity). I am not sure, at what level I stand as a newbie. I bought this Asus Eee PC two days back. The model is Asus 1015CX. See the specs here http://www.flipkart.com/asus-1015cx-blk011w-laptop-2nd-gen-atom-dual-core-1gb-320gb-linux/p/itmd8qu4quzu8srr . I created a live USB to install 12.10. The usb booted fine. When I clicked "Try Ubuntu" option, it showed me a black screen with a cursor blinking. I waited for 15 minutes and had to restart using the power button. On clicking the "Install Ubuntu" button, the install process went seamlessly. [I have a Windows7 installed on one of the partitions]. i installed it alongside previous windows installation. The system was then rebooted for the first time. It showed the GRUB menu and I selected the first option Ubuntu. After showing the splash screen for a second, it began showing various messages on a black screen and then it struck on "Stopping Save kernel state message". I had to force shut the system using power button. Sometimes it just gives a blank screen with a cursor blinking and on pressing power button, some messages stating that acpid is doing something and stopping services pops up and the system shuts down. I tried booting with "nomodeset" and other parameters as directed in solution to previous such problems on forums. Also Ctrl+Alt+F1,F2,F3,F4,F5,F6..F12 is not doing anything for me anywhere. At installation, I checked Login automatically option. On booting into recovery several options comes up. Clicking resume just gives me a blank screen with cursor blinking. on dropping to root shell and remounting filesystem as RW, I am able to supply some command that worked for others. startx -- Several messages comes up with last one stating Fatal error: No screen found sudo service lightdm start -- Gives a blank screen with a cursor blinking lspci | grep VGA -- Shows some Intel Integrated Graphic... something I don't remember I had reconfigured xserver-xorg, lightdm, reinstalled ubuntu-desktop, unity. What should I do..?? Will going back to 11.04 work..?? Or I should leave all hopes of running Ubuntu on my netbook. Please help.

  • How to build a Singleton-like dependency injector replacement (Php)

    - by Erparom
    I know out there are a lot of excelent containers, even frameworks almost entirely DI based with good strong IoC classes. However, this doesn't help me to "define" a new pattern. (This is Php code but understandable to anyone) Supose we have: //Declares the singleton class bookSingleton { private $author; private static $bookInstance; private static $isLoaned = FALSE; //The private constructor private function __constructor() { $this->author = "Onecrappy Writer Ofcheap Novels"; } //Sets the global isLoaned state and also gets self instance public static function loanBook() { if (self::$isLoaned === FALSE) { //Book already taken, so return false return FALSE; } else { //Ok, not loaned, lets instantiate (if needed and loan) if (!isset(self::$bookInstance)) { self::$bookInstance = new BookSingleton(); } self::$isLoaned = TRUE; } } //Return loaned state to false, so another book reader can take the book public function returnBook() { $self::$isLoaned = FALSE; } public function getAuthor() { return $this->author; } } Then we get the singelton consumtion class: //Consumes the Singleton class BookBorrower() { private $borrowedBook; private $haveBookState; public function __construct() { this->haveBookState = FALSE; } //Use the singelton-pattern behavior public function borrowBook() { $this->borrowedBook = BookSingleton::loanBook(); //Check if was successfully borrowed if (!this->borrowedBook) { $this->haveBookState = FALSE; } else { $this->haveBookState = TRUE; } } public function returnBook() { $this->borrowedBook->returnBook(); $this->haveBookState = FALSE; } public function getBook() { if ($this->haveBookState) { return "The book is loaned, the author is" . $this->borrowedbook->getAuthor(); } else { return "I don't have the book, perhaps someone else took it"; } } } At last, we got a client, to test the behavior function __autoload($class) { require_once $class . '.php'; } function write ($whatever,$breaks) { for($break = 0;$break<$breaks;$break++) { $whatever .= "\n"; } echo nl2br($whatever); } write("Begin Singleton test", 2); $borrowerJuan = new BookBorrower(); $borrowerPedro = new BookBorrower(); write("Juan asks for the book", 1); $borrowerJuan->borrowBook(); write("Book Borrowed? ", 1); write($borrowerJuan->getAuthorAndTitle(),2); write("Pedro asks for the book", 1); $borrowerPedro->borrowBook(); write("Book Borrowed? ", 1); write($borrowerPedro->getAuthorAndTitle(),2); write("Juan returns the book", 1); $borrowerJuan->returnBook(); write("Returned Book Juan? ", 1); write($borrowerJuan->getAuthorAndTitle(),2); write("Pedro asks again for the book", 1); $borrowerPedro->borrowBook(); write("Book Borrowed? ", 1); write($borrowerPedro->getAuthorAndTitle(),2); This will end up in the expected behavior: Begin Singleton test Juan asks for the book Book Borrowed? The book is loaned, the author is = Onecrappy Writer Ofcheap Novels Pedro asks for the book Book Borrowed? I don't have the book, perhaps someone else took it Juan returns the book Returned Book Juan? I don't have the book, perhaps someone else took it Pedro asks again for the book Book Borrowed? The book is loaned, the author is = Onecrappy Writer Ofcheap Novels So I want to make a pattern based on the DI technique able to do exactly the same, but without singleton pattern. As far as I'm aware, I KNOW I must inject the book inside "borrowBook" function instead of taking a static instance: public function borrowBook(BookNonSingleton $book) { if (isset($this->borrowedBook) || $book->isLoaned()) { $this->haveBook = FALSE; return FALSE; } else { $this->borrowedBook = $book; $this->haveBook = TRUE; return TRUE; } } And at the client, just handle the book: $borrowerJuan = new BookBorrower(); $borrowerJuan-borrowBook(new NonSingletonBook()); Etc... and so far so good, BUT... Im taking the responsability of "single instance" to the borrower, instead of keeping that responsability inside the NonSingletonBook, that since it has not anymore a private constructor, can be instantiated as many times... making instances on each call. So, What does my NonSingletonBook class MUST be in order to never allow borrowers to have this same book twice? (aka) keep the single instance. Because the dependency injector part of the code (borrower) does not solve me this AT ALL. Is it needed the container with an "asShared" method builder with static behavior? No way to encapsulate this functionallity into the Book itself? "Hey Im a book and I shouldn't be instantiated more than once, I'm unique"

  • Tic Tac Toe Winner in Javascript and html [closed]

    - by Yehuda G
    I am writing a tic tac toe game using html, css, and JavaScript. I have my JavaScript in an external .js file being referenced into the .html file. Within the .js file, I have a function called playerMove, which allows the player to make his/her move and switches between player 'x' and 'o'. What I am trying to do is determine the winner. Here is what I have: each square, when onclick(this), references playerMove(piece). After each move is made, I want to run an if statement to check for the winner, but am unsure if the parameters would include a reference to 'piece' or a,b, and c. Any suggestions would be greatly appreciated. Javascript: var turn = 0; a = document.getElementById("topLeftSquare").innerHTML; b = document.getElementById("topMiddleSquare").innerHTML; c = document.getElementById("topRightSquare").innerHTML; function playerMove(piece) { var win; if(piece.innerHTML != 'X' && piece.innerHTML != 'O'){ if(turn % 2 == 0){ document.getElementById('playerDisplay').innerHTML= "X Plays " + printEquation(1); piece.innerHTML = 'X'; window.setInterval("X", 10000) piece.style.color = "red"; if(piece.innerHTML == 'X') window.alert("X WINS!"); } else { document.getElementById('playerDisplay').innerHTML= "O Plays " + printEquation(1); piece.innerHTML = 'O'; piece.style.color = "brown"; } turn+=1; } html: <div id="board"> <div class="topLeftSquare" onclick="playerMove(this)"> </div> <div class="topMiddleSquare" onclick="playerMove(this)"> </div> <div class="topRightSquare" onclick="playerMove(this)"> </div> <div class="middleLeftSquare" onclick="playerMove(this)"> </div> <div class="middleSquare" onclick="playerMove(this)"> </div> <div class="middleRightSquare" onclick="playerMove(this)"> </div> <div class="bottomLeftSquare" onclick="playerMove(this)"> </div> <div class="bottomMiddleSquare" onclick="playerMove(this)"> </div> <div class="bottomRightSquare" onclick="playerMove(this)"> </div> </div>

  • Master Data Management Implementation Styles

    - by david.butler(at)oracle.com
    In any Master Data Management solution deployment, one of the key decisions to be made is the choice of the MDM architecture. Gartner and other analysts describe some different Hub deployment styles, which must be supported by a best of breed MDM solution in order to guarantee the success of the deployment project.   Registry Style: In a Registry Style MDM Hub, the various source systems publish their data and a subscribing Hub stores only the source system IDs, the Foreign Keys (record IDs on source systems) and the key data values needed for matching. The Hub runs the cleansing and matching algorithms and assigns unique global identifiers to the matched records, but does not send any data back to the source systems. The Registry Style MDM Hub uses data federation capabilities to build the "virtual" golden view of the master entity from the connected systems.   Consolidation Style: The Consolidation Style MDM Hub has a physically instantiated, "golden" record stored in the central Hub. The authoring of the data remains distributed across the spoke systems and the master data can be updated based on events, but is not guaranteed to be up to date. The master data in this case is usually not used for transactions, but rather supports reporting; however, it can also be used for reference operationally.   Coexistence Style: The Coexistence Style MDM Hub involves master data that's authored and stored in numerous spoke systems, but includes a physically instantiated golden record in the central Hub and harmonized master data across the application portfolio. The golden record is constructed in the same manner as in the consolidation style, and, in the operational world, Consolidation Style MDM Hubs often evolve into the Coexistence Style. The key difference is that in this architectural style the master data stored in the central MDM system is selectively published out to the subscribing spoke systems.   Transaction Style: In this architecture, the Hub stores, enhances and maintains all the relevant (master) data attributes. It becomes the authoritative source of truth and publishes this valuable information back to the respective source systems. The Hub publishes and writes back the various data elements to the source systems after the linking, cleansing, matching and enriching algorithms have done their work. Upstream, transactional applications can read master data from the MDM Hub, and, potentially, all spoke systems subscribe to updates published from the central system in a form of harmonization. The Hub needs to support merging of master records. Security and visibility policies at the data attribute level need to be supported by the Transaction Style hub, as well.   Adaptive Transaction Style: This is similar to the Transaction Style, but additionally provides the capability to respond to diverse information and process requests across the enterprise. This style emerged most recently to address the limitations of the above approaches. With the Adaptive Transaction Style, the Hub is built as a platform for consolidating data from disparate third party and internal sources and for serving unified master entity views to operational applications, analytical systems or both. This approach delivers a real-time Hub that has a reliable, persistent foundation of master reference and relationship data, along with all the history and lineage of data changes needed for audit and compliance tracking. On top of this persistent master data foundation, the Hub can dynamically aggregate transaction data on demand from different source systems to deliver the unified golden view to downstream systems. Data can also be accessed through batch interfaces, published to a message bus or served through a real-time services layer. New data sources can be readily added in this approach by extending the data model and by configuring the new source mappings and the survivorship rules, meaning that all legacy data hubs can be leveraged to contribute their records/rules into the new transaction hub. Finally, through rich user interfaces for data stewardship, it allows exception handling by business analysts to keep it current with business rules/practices while maintaining the reliability of best-of-breed master records.   Confederation Style: In this architectural style, several Hubs are maintained at departmental and/or agency and/or territorial level, and each of them are connected to the other Hubs either directly or via a central Super-Hub. Each Domain level Hub can be implemented using any of the previously described styles, but normally the Central Super-Hub is a Registry Style one. This is particularly important for Public Sector organizations, where most of the time it is practically or legally impossible to store in a single central hub all the relevant constituent information from all departments.   Oracle MDM Solutions can be deployed according to any of the above MDM architectural styles, and have been specifically designed to fully support the Transaction and Adaptive Transaction styles. Oracle MDM Solutions provide strong data federation and integration capabilities which are key to enabling the use of the Confederated Hub as a possible architectural style approach. Don't lock yourself into a solution that cannot evolve with your needs. With Oracle's support for any type of deployment architecture, its ability to leverage the outstanding capabilities of the Oracle technology stack, and its open interfaces for non-Oracle technology stacks, Oracle MDM Solutions provide a low TCO and a quick ROI by enabling a phased implementation strategy.

  • Retreiving upcoming calendar events from a Google Calendar

    - by brian_ritchie
    Google has a great cloud-based calendar service that is part of their Gmail product.  Besides using it as a personal calendar, you can use it to store events for display on your web site.  The calendar is accessible through Google's GData API for which they provide a C# SDK. Here's some code to retrieve the upcoming entries from the calendar:  .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: Consolas, "Courier New", Courier, Monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } 1: public class CalendarEvent 2: { 3: public string Title { get; set; } 4: public DateTime StartTime { get; set; } 5: } 6:   7: public class CalendarHelper 8: { 9: public static CalendarEvent[] GetUpcomingCalendarEvents 10: (int numberofEvents) 11: { 12: CalendarService service = new CalendarService("youraccount"); 13: EventQuery query = new EventQuery(); 14: query.Uri = new Uri( 15: "http://www.google.com/calendar/feeds/userid/public/full"); 16: query.FutureEvents = true; 17: query.SingleEvents = true; 18: query.SortOrder = CalendarSortOrder.ascending; 19: query.NumberToRetrieve = numberofEvents; 20: query.ExtraParameters = "orderby=starttime"; 21: var events = service.Query(query); 22: return (from e in events.Entries select new CalendarEvent() 23: { StartTime=(e as EventEntry).Times[0].StartTime, 24: Title = e.Title.Text }).ToArray(); 25: } 26: } There are a few special "tricks" to make this work: "SingleEvents" flag will flatten out reoccurring events "FutureEvents", "SortOrder", and the "orderby" parameters will get the upcoming events. "NumberToRetrieve" will limit the amount coming back  I then using Linq to Objects to put the results into my own DTO for use by my model.  It is always a good idea to place data into your own DTO for use within your MVC model.  This protects the rest of your code from changes to the underlying calendar source or API.

  • High Jinks, Hi Jacks, Exceptional DBA Awards and PASS

    - by Rodney
    The countdown to PASS has counted down.  The day after tomorrow I will board a plane, like many others, on my way for the 4th year in a row to SQL PASS Summit.  The anticipation has been excruciating but luckily I have this little thing called a day job as a DBA that has kept me busy and not thinking too much about the event. Well that is not exactly true since my beautiful wife works for PASS so we get to talk about SQL from the time we wake up until late in the evening. I would not have it any other way and I feel very fortunate to be a part of this great event and to have been chosen as the Exceptional DBA Award judge also for the 4th year in a row.  This year, I will have been again tasked with presenting the award to the winner, Mr. Jeff Moden and it will be a true honor to meet him in person as I have read many of his articles on SSC and have attended his session at PASS previously.  The speech is all ready but one item remains, which will be a surprise to all who attend the party on Tuesday night in Seattle (see links below).  Let's face it, Exceptional DBAs everywhere work very hard protecting our data stores, tuning queries, mentoring, saving money, installing clusters, etc and once in a while there is time to be exceptionally non-professional and have a bit of fun. Once incident that happened this year that falls under the High Jinks category was when my network admin asked if I could Telnet into a SQL instance and see if I could make the connection through the firewall that he had just configured. I was able to establish a connection on port 1433 and it occurred to me that it would be very interesting if I could actually run T-SQL queries via a Telnet session much like you might do with an SMTP server. With that thought, I proceeded to demonstrate this could be possible by convincing my senior DBA Shawn McGehee that I was able to do so. At first he did not believe me. It shook his world view.  It was inconceivable.  What I had done, behind the scenes, of course, was to copy and rename SQLCMD.exe to Telnet.exe and used it to connect and run a simple, "Select * from sys.databases" on the SQL instance. I think if it had been anyone other than Shawn I could have extended this ruse indefinitely but he caught on within 30 seconds. It was a fun thirty seconds though. On the High Jacks side of the house, which is really merged to be SQL HACKS, I finally, after several years of struggling with how to connect to an untrusted domain like in a DMZ with a windows account in SSMS, I stumbled upon a solution that does away with the requirement to use SQL Authentication.  While "Runas" is a great command to use to run an application with a higher privileged account, I had not previously been able to figure out how to connect to the remote domain with SSMS and "Runsas". It never connected and caused a login failure every time for the remote windows domain account. Then I ran across an option for "Runas",   "/netonly".  This option postpones the login until a connection is made and only then passes the remote login you supply when you first launch SSMS with the "Runas" command. So a typical shortcut would look like: "C:\Windows\System32\runas.exe /netonly /user:remotedomain.com\rodlandrum "C:\Program Files\Microsoft SQL Server\100\Tools\Binn\VSShell\Common7\IDE\Ssms.exe" You will want to make sure the passwords are synced between the two domains, your local domain and the remote domain, otherwise you may have account lockout issues, but I have found in weeks of testing this is a stable solution. Now it is time to get ready to head for Seattle. Please, if you see me (@SQLBeat) or my wife (@Karlakay22) please run up and high five me (wait..High Jinks.High Jacks.High Fives.Need to change the title) or give me a big bear hug if you are strong enough to lift me off the ground. And if you do actually do that, I will think you are awesome and will not embarrass you by crying out for help or complaining of a broken back or sciatic nerve damage. And now the links to others who have all of the details. First, for the MVP Deep Dives 2, of which, like John, I was lucky enough to be able to participate in this year. http://www.simple-talk.com/community/blogs/johnm/archive/2011/09/29/103577.aspx And the details of the SSC party where the Exceptional DBA of 2011, Jeff Moden, will be awarded. http://www.simple-talk.com/community/blogs/rebecca_amos/archive/2011/10/05/103661.aspx   Cheers!

  • Canonicalization of single, small pages like reviews or product categories

    - by Valorized
    In general I pretty much like the idea of canonicalization. And in most cases, Google explains possible procedures in a clear way. For example: If I have duplicates because of parameters (eg: &sort=desc) it's clear to use the canonical for the site, provided the within the head-tag. However I'm wondering how to handle "small - no to say thin content - sites". What's my definition of a small site? An Example: On one of my main sites, we use a directory based url-structure. Let's see: example.com/ (root) example.com/category-abc/ example.com/category-abc/produkt-xy/ Moreover we provide on page, that includes all products example.com/all-categories/ (lists all products the same way as in the categories) In case of reviews, we use a similar structure: example.com/reviews/product-xy/ shows all review for one certain product example.com/reviews/product-xy/abc-your-product-is-great/ shows one certain review example.com/reviews/ shows all reviews for all products (latest first) Let's make it even more complicated: On every product site, there are the latest 2 reviews at the end of the page. So you see, a lot of potential duplicates. Q1: Should I create canonicals for a: example.com/category-abc/ to example.com/all-categories/ b: example.com/reviews/product-xy/abc-your-product-is-great/ to example.com/reviews/product-xy/ or to example.com/review/ or none of them? Q2: Can I link the collection of categories (all-categories/) and collection of all reviews (reviews/ and reviews/product-xy/) to the single category respectively to the single review. Example: example.com/reviews/ includes - let's say - 100 reviews. Can I somehow use a markup that tells search engines: "Hey, wait, you are now looking at a collection of 100 reviews - do not index this collection, you should rather prefer indexing every single review as a single page!". In HTML it might be something like that (which - of course - does not work, it's only to show you what I mean): <div class="review" rel="canonical" href="http://example.com/reviews/product-xz/abc-your-product-is-great/"> HERE GOES THE REVIEW</div> Reason: I don't think it is a great user experience if the user searches for "your product is great" and lands on example.com/reviews/ instead of example.com/reviews/product-xy/abc-your-product-is-great/. On the first site, he will have to search and might stop because of frustration. The second result, however, might lead to a conversion. The same applies for categories. If the user is searching for category-Z, he might land on the all-categories page and he has to scroll down to the (last) category, to find what he searched for (Z). So what's best practice? What should I do?

  • BizTalk 2009 - Creating a Custom Functoid Library

    - by StuartBrierley
    If you find that you have a need to created multiple Custom Functoids you may also choose to create a Custom Functoid Library - a single project containing many custom functoids.  As previsouly discussed, the Custom Functoid Wizard can be used to create a project with a new custom functoid inside.  But what if you want to extend this project to include more custom functoids and create your Custom Functoid Library?  First create a Custom Functoid Library project and your first Custom Functoid using the Custom Functoid Wizard. When you open your Custom Functoid Library project in Visual Studio you will see that it contains your custom functoid class file along with its resource file.  One of the items this resource file contains is the ID of the the custom functoid.  Each custom functoid needs a unique ID that is over 6000.  When creating a Custom Functoid Library I would first suggest that you delete the ID from this resource file and instead create a _FunctoidIDs class containing constants for each of your custom functoids.  In this way you can easily see which custom functoid IDs are assigned to which custom functoid and which ID is next in the sequence of availability: namespace MyCompany.BizTalk.Functoids.TestFunctoids {     class _FunctoidIDs     {         public const int TestFunctoid                       = 6001;     } } You will then need to update the base() function in your existing functoid class to reference these constant values rather than the current resource file. From:    int functoidID;    // This has to be a number greater than 6000    functoidID = System.Convert.ToInt32(resmgr.GetString("FunctoidId"));    this.ID = functoidID; To: this.ID = _FunctoidIDs.TestFunctoid; To create a new custom functoid you can copy the existing custom functoid, renaming the resultant class file as appropriate.  Once it is renamed you will need to change the Class name, ResourceName reference and Base function name in the class code to those of your new custom functoid.  You will also need to create a new constant value in the _FunctoidIDs class and update the ID reference in your code to match this.  Assuming that you need some different functionalty from your new  customfunctoid you will need to check or amend the following in your functoid class file: Min and Max connections Functoid Category Input and Output connection types The parameters and functionality of the Execute function To change the appearance of you new custom functoid you will need to check or amend the following in the functoid resource file: Name Description Tooltip Exception Icon You can change the String values by double clicking the resource file and amending the value fields in the string table. To amend the functoid icon you will need to create a 16x16 bitmap image.  Once you have saved this you are then ready to import it into the functoid resource file.  In Visual Studio change the resource view to images, right click the icon and choose import from file. You have now completed your new custom functoid and created a Custom Functoid Library.  You can test your new library of functoids by building the project, copying the resultant DLL to C:\Program Files\Microsoft BizTalk Server 2009\Developer Tools\Mapper Extensions and then resetting the toolbox in Visual Studio.

  • Using runtime checking of code contracts in Visual Studio 2010

    - by DigiMortal
    In my last posting about code contracts I introduced how to check input parameters of randomizer using static contracts checking. But you can also compile code contracts to your assemblies and use them also in runtime. In this posting I will show you simple example about runtime checking of code contracts. NB! If you want to play with code and try out things described here feel free to download example solution. if you are speaker and want to use this solution as a part of your sessions then feel free to do so, but don’t forget to refer me and this blog as source of this solution. And please let me know about your session. As a speaker I am very interested about it. :) To see how code contracts are checked at runtime we have to enable runtime checking from project properties. Make sure you have checked the box “Perform Runtime Contract Checking” and make sure you select “Full” from dropdown. These parts are in red box on the screenshot below. Visual Studio 2010 settings for code contracts. Runtime Checking is turned on and checks are made only in public surface. Click on image to see it at original size.  Save project settings. Then compile code and run it. As soon as code execution hits the call to GetRandomFromRangeContracted() exception is thrown. If you are not currently playing with solution referred above take a look at the following screenshot. Visual Studio 2010 runtime checking of code contracts. Exception of type ContractException is thrown when contract is violated. Click on image to see it at original size.  The exact type of exception is ContractException and it is defined in System.Diagnostics.Contracts.__ContractsRuntime namespace. In our example the message of exception is following: "Precondition failed: min < max  Min must be less than max" Besides the description we inserted for the case contract violation the message also contains violated contract type. In this case the type of contract is Precondition. Conclusion Using runtime checking of code contracts enables you to take code contracts with your code and have them checked every time when your methods are called. This way you can assure that all conditions are met to run method or exception is thrown and calling system has to handle the situation.

  • Designing for an algorithm that reports progress

    - by Stefano Borini
    I have an iterative algorithm and I want to print the progress. However, I may also want it not to print any information, or to print it in a different way, or do other logic. In an object oriented language, I would perform the following solutions: Solution 1: virtual method have the algorithm class MyAlgoClass which implements the algo. The class also implements a virtual reportIteration(iterInfo) method which is empty and can be reimplemented. Subclass the MyAlgoClass and override reportIteration so that it does what it needs to do. This solution allows you to carry additional information (for example, the file unit) in the reimplemented class. I don't like this method because it clumps together two functionalities that may be unrelated, but in GUI apps it may be ok. Solution 2: observer pattern the algorithm class has a register(Observer) method, keeps a list of the registered observers and takes care of calling notify() on each of them. Observer::notify() needs a way to get the information from the Subject, so it either has two parameters, one with the Subject and the other with the data the Subject may pass, or just the Subject and the Observer is now in charge of querying it to fetch the relevant information. Solution 3: callbacks I tend to see the callback method as a lightweight observer. Instead of passing an object, you pass a callback, which may be a plain function, but also an instance method in those languages that allow it (for example, in python you can because passing an instance method will remain bound to the instance). C++ however does not allow it, because if you pass a pointer to an instance method, this will not be defined. Please correct me on this regard, my C++ is quite old. The problem with callbacks is that generally you have to pass them together with the data you want the callback to be invoked with. Callbacks don't store state, so you have to pass both the callback and the state to the Subject in order to find it at callback execution, together with any additional data the Subject may provide about the event is reporting. Question My question is relative to the fact that I need to implement the opening problem in a language that is not object oriented, namely Fortran 95, and I am fighting with my usual reasoning which is based on python assumptions and style. I think that in Fortran the concept is similar to C, with the additional trouble that in C you can store a function pointer, while in Fortran 95 you can only pass it around. Do you have any comments, suggestions, tips, and quirks on this regard (in C, C++, Fortran and python, but also in any other language, so to have a comparison of language features that can be exploited on this regard) on how to design for an algorithm that must report progress to some external entity, using state from both the algorithm and the external entity ?

  • How do I reconfigure my GLES frame buffer after a rotation?

    - by Panda Pajama
    I am implementing interface rotation for my GLES based game for iOS, written in Xamarin.iOS with OpenTK. I am detecting the rotation by overriding WillRotate, in my UIViewController, and I correctly re-setup all of my projection matrices. However, when drawing a sprite, the image looks a bit blurrier on the landscape version compared to the portrait version, as you can see in the following closeups magnified 10x. Portrait (before rotating) Landscape (after rotating) In both cases, I'm using the same texture with the same sampler, the same shader, and the same GL state. I just changed the order of the parameters in the projection matrix, so the resulting sizes should be exactly the same pixelwise. Since this could be thought of as a window resize, I suppose that the framebuffer has to be recreated to the new size. When working on desktop apps on Direct3D11 (SharpDX), I would have to call swapChain.ResizeBuffers() to do this. I have tried setting AutoResize = true in my iPhoneOSGameView, but then the framebuffer gets clipped as I rotate the interface, and then everything disappears when rotating the interface again. I'm not doing anything strange, my framebuffer initialization is pretty vanilla: int scaling = (int)UIScreen.MainScreen.Scale; DeviceWidth = (int)UIScreen.MainScreen.Bounds.Width * scaling; DeviceHeight = (int)UIScreen.MainScreen.Bounds.Height * scaling; Size = new System.Drawing.Size((int)(DeviceWidth), (int)(DeviceHeight)); Bounds = new System.Drawing.RectangleF(0, 0, DeviceWidth, DeviceHeight); Frame = new System.Drawing.RectangleF(0, 0, DeviceWidth, DeviceHeight); ContextRenderingApi = EAGLRenderingAPI.OpenGLES2; AutoResize = true; LayerRetainsBacking = true; LayerColorFormat = EAGLColorFormat.RGBA8; I get inconsistent results when changing Size, Bounds and Frame on my CreateFrameBuffer override, but since the documentation is so incomplete (it has nothing on Bounds and Frame), I have resorted to randomly changing stuff here and there without really knowing what is going on. There is a similar question which has no answers. However, I don't know if they're experiencing the same problem as I am. Is my supposition that recreating the framebuffer is necessary, correct? If so, does anybody know how to do it correctly in OpenTK for Xamarin.iOS?

  • Oracle GoldenGate 12c - Leading Enterprise Replication

    - by Doug Reid
    Oracle GoldenGate 12c released  on October 17th and includes several new cutting edge features that firmly establishes GoldenGate's leader position in the data replication space.   In fact, this release more than doubles the performance of data delivery, supports Oracle's new multitenant database feature,  it's more secure, has more options for high availability, and has made great strides to simplify the configuration and deployment of the product.     Read through the press release if you haven't already and do not miss the quote from Cern's Eva Dafonte Perez, regarding Oracle GoldenGate 12c "….performs five times faster compared to previous GoldenGate versions and simplifies the management of a multi-tier environment" There are a variety of new and improved features in the Oracle GoldenGate 12c.  Here are the highlights: Optimized for Oracle Database 12c -  GoldenGate 12c is custom tailored to the unique capabilities of Oracle database 12c and out of the box GoldenGate 12c supports multitenant (pluggable database (PDB)) and non-consolidated deployments of Oracle Database 12c.   The naming convention used by database 12c is now in three parts (PDB-name, schema-name, and object name).  We have made changes to the GoldenGate capture process to support the new naming convention and streamlined the whole process so a single GoldenGate capture process is being used at the container level rather than at each individual PDB.  By having the capture process at the container level resource usage and the number of processes are reduced. To view a conceptual architecture diagram click here. Integrated Delivery for the Oracle Database - Leveraging a lightweight streaming API built exclusively for Oracle GoldenGate 12c, this process distributes load, auto tunes the degree of parallelism, scales better, and delivers blinding rates of changed data delivery to the Oracle database.  One of the goals for Oracle GoldenGate 12c was to reduce IT costs by simplifying the configuration and reduce the time to manage complex infrastructures.  In previous versions of Oracle GoldenGate, customers would split transaction loads by grouping tables into multiple different delivery processes (click here to view the previous method). Each delivery process executed independently and without any interaction or knowledge of other delivery processes.  This setup was complicated to configure and time consuming as the developer needed in-depth knowledge of the source and target schemas and the transaction profile. With GoldenGate 12c and Integrated Delivery we have made it easier to configure and faster to deploy.  To view a conceptual architecture diagram of integrated delivery click here Coordinated Delivery for Non-Oracle Databases - Coordinated Delivery orchestrates high-speed apply processes and simplifies the configuration of GoldenGate for non-Oracle targets. In Oracle GoldenGate 12c a single delivery process is used with multiple threads (click here) and key events, such as primary key updates, event markers, DDL, etc, are coordinated between the various threads to insure that the transactions are applied in the same sequence as they were captured, all while delivery improved performance.  Replication Between On-Premises and Cloud-Based systems. - The trend for business to utilize both on-premises and cloud-based systems is rising and businesses need to replicate data back and forth.   GoldenGate 12c can be configured in a variety of ways to provide real-time replication when unrestricted or restricted (limited ports or HTTP tunneling) networks are between on-premises and cloud-based systems.    Expanded Heterogeneity - It wouldn't be a GoldenGate release without new and improved platform support.   Release 1 includes support for MySQL 5.6 and Sybase 15.7.   Upcoming in the next release GoldenGate, support will be expanded for MS SQL Server, DB2, and Teradata. Tighter Security - Oracle GoldenGate 12c is integrated with the Oracle wallet to shield usernames and passwords using strong encryption and aliases.   Customers accustomed to using the Oracle Wallet with other Oracle products will instantly be familiar with how to use this great new feature Expanded Oracle Application and Technology Support -   GoldenGate can be used along with Oracle Coherence to enable real-time changed data feeds to the Coherence cache using Toplink and the Oracle GoldenGate JMS adapter.     Plus,  Oracle Advanced Customer Services (ACS) now offers a low downtime E-Business Suite platform and database migrations using GoldenGate as the enabling technology.  Keep tuned for more blogs on the new features and the upcoming launch webcast where we will go into these new features in more detail.   In the mean time make sure to read through our white paper "Oracle GoldenGate 12c Release 1 New Features Overview"

  • Walmart and Fusion Apps

    - by ultan o'broin
    Photograph: Misha Vaughan I attended Fusion Apps (yes, I know I am supposed to say "Oracle Fusion Applications", but stuffy old style guides are a turn-off in interwebs conversations) User Experience Advocate (FXA) training in Long Beach, California last week; a suitable location as ODTUG KSCOPE 11 was kicking off and key players were in the area. As a member of Oracle's Apps-UX team I know the Fusion Apps messaging, natch, and done some other Fusion Apps go-to-market content work too. For the messaging details themselves, see Lonneke Dikmans (@lonnekedikmans) great blog, by the way. However, I wanted some 'formal' training combined with the opportunity to meet and learn from people already out there delivering those messages. The idea in me reaching out to Misha Vaughan, Apps-UX FXA maven, to get me onto this training was that in addition to my UX knowledge, I could leverage my location in EMEA and hit up customer events more quickly and easily. Those local user groups do like to hear the voice of locals too you know (so I need to work on that mid-Atlantic accent). I'm looking forward to such opportunities. The training was all smashing stuff, just the right level of detail, delivered professionally and with great style and humor. I was especially honored to be paired off for my er, coaching with Debra Lilley (@debralilley), who shared with everyone all kinds of tips and insights from her experiences of delivering the message and demo. For me, that was the real power of the FXA event--the communal, conversational aspect--the meeting up with people who had done all this for real, the sharing in their experiences, while learning along with other newbies. Sorry, but that all-important social aspect doesn't work so well with remote meetings. Katie Candland (Apps-UX) gave us a great tour of the Fusion Apps demo and included some useful presentational tips too (any excuse to buy that iPad). It's clear to me that the Fusion Apps messaging and demos really come alive with real-world examples that local application users will recognize, and I picked up some "yes, that's my job made easier" scene-stealers from Debra and Karen Brownfield too, to add to the great ones already provided. This power of examples shouldn't surprise anyone, they've long been a mainstay of applications user assistance, popular with users. We'll offer customers different types of example topics in the Fusion Apps online help too (stay tuned), and we know from research how important those 3S's (stories, scenarios, and simulations) are to users when they consume and apply information. Well, we've got the simulation, now it's time for more stories and scenarios. If you get a chance to participate in an FXA event (whether you are an Oracle employee or otherwise), I'd encourage it. It's committing your time and energy for sure, but I got real bang for the buck from it for my everyday job too. Listening to the room's feedback on the application demo really brought our internal design work to life, and I picked up on some things that I need to follow up on (like how you alphabetically sort stuff in other languages). User experience is after all, about users. What will I be doing next, and what would I like to see happen? Obviously, I need to develop my story-telling links with the people I met in Long Beach and do some practicing with the materials, and then get out there and deliver them at a suitable location. The demo is what it is right now, and that's a super-rich demo that I know everyone will want to see and ask questions about. Then, as mentioned by attendees at the FXA event, follow up on those translated and localized messages for EMEA (and APAC), that deal with different statutory or reporting requirements of the target markets. Given my background I would say that, wouldn't I? However, language is part of the UX, and international revenue is greater than US-only revenue for Oracle, so yes dear, we all need to get over the fact that enterprise apps users don't all speak, or want to speak, American-English. Most importantly perhaps, the continued development of a strong messaging community between Oracle and partners and customers where we can swap and share those FXA messaging stories and scenarios about Fusion Apps in a conversational way. The more the better, a combination of online and face-to-face meetings. I must also mention the great dinner after the event at Parker's Lighthouse, and the fun myself and Andrew Gilmour (Apps-UX) had at our end of the table talking about just about everything except Fusion Apps with Ronald Van Luttikhuizen and Ben Prusinski (who now understands the difference between Cork and Dublin people. I hope). Thanks to all the Apps-UXers who helped bring the FXA training to town, and to Debra and all the others that I am too jetlagged to mention right who were instrumental in making it happen for me. Here's to the next one. And the Walmart angle? That was me doing my Robert Scoble (ScO'bilizer?)-style guerilla smart phone research in Walmart in Long Beach, before the FXA event. It's all about stories for me. You can read more about it on the appslab blog (see the comments).

  • Design Pattern for Complex Data Modeling

    - by Aaron Hayman
    I'm developing a program that has a SQL database as a backing store. As a very broad description, the program itself allows a user to generate records in any number of user-defined tables and make connections between them. As for specs: Any record generated must be able to be connected to any other record in any other user table (excluding itself...the record, not the table). These "connections" are directional, and the list of connections a record has is user ordered. Moreover, a record must "know" of connections made from it to others as well as connections made to it from others. The connections are kind of the point of this program, so there is a strong possibility that the number of connections made is very high, especially if the user is using the software as intended. A record's field can also include aggregate information from it's connections (like obtaining average, sum, etc) that must be updated on change from another record it's connected to. To conserve memory, only relevant information must be loaded at any one time (can't load the entire database in memory at load and go from there). I cannot assume the backing store is local. Right now it is, but eventually this program will include syncing to a remote db. Neither the user tables, connections or records are known at design time as they are user generated. I've spent a lot of time trying to figure out how to design the backing store and the object model to best fit these specs. In my first design attempt on this, I had one object managing all a table's records and connections. I attempted this first because it kept the memory footprint smaller (records and connections were simple dicts), but maintaining aggregate and link information between tables became....onerous (ie...a huge spaghettified mess). Tracing dependencies using this method almost became impossible. Instead, I've settled on a distributed graph model where each record and connection is 'aware' of what's around it by managing it own data and connections to other records. Doing this increases my memory footprint but also let me create a faulting system so connections/records aren't loaded into memory until they're needed. It's also much easier to code: trace dependencies, eliminate cycling recursive updates, etc. My biggest problem is storing/loading the connections. I'm not happy with any of my current solutions/ideas so I wanted to ask and see if anybody else has any ideas of how this should be structured. Connections are fairly simple. They contain: fromRecordID, fromTableID, fromRecordOrder, toRecordID, toTableID, toRecordOrder. Here's what I've come up with so far: Store all the connections in one big table. If I do this, either I load all connections at once (one big db call) or make a call every time a user table is loaded. The big issue here: the size of the connections table has the potential to be huge, and I'm afraid it would slow things down. Store in separate tables all the outgoing connections for each user table. This is probably the worst idea I've had. Now my connections are 'spread out' over multiple tables (one for each user table), which means I have to make a separate DB called to each table (or make a huge join) just to find all the incoming connections for a particular user table. I've avoided making "one big ass table", but I'm not sure the cost is worth it. Store in separate tables all outgoing AND incoming connections for each user table (using a flag to distinguish between incoming vs outgoing). This is the idea I'm leaning towards, but it will essentially double the total DB storage for all the connections (as each connection will be stored in two tables). It also means I have to make sure connection information is kept in sync in both places. This is obviously not ideal but it does mean that when I load a user table, I only need to load one 'connection' table and have all the information I need. This also presents a separate problem, that of connection object creation. Since each user table has a list of all connections, there are two opportunities for a connection object to be made. However, connections objects (designed to facilitate communication between records) should only be created once. This means I'll have to devise a common caching/factory object to make sure only one connection object is made per connection. Does anybody have any ideas of a better way to do this? Once I've committed to a particular design pattern I'm pretty much stuck with it, so I want to make sure I've come up with the best one possible.

  • WPF: Reloading app parts to handle persistence as well as memory management.

    - by Ingó Vals
    I created a app using Microsoft's WPF. It mostly handles data reading and input as well as associating relations between data within specific parameters. As a total beginner I made some bad design decision ( not so much decisions as using the first thing I got to work ) but now understanding WPF better I'm getting the urge to refactor my code with better design principles. I had several problems but I guess each deserves it's own question for clarity. Here I'm asking for proper ways to handle the data itself. In the original I wrapped each row in a object when fetched from database ( using LINQ to SQL ) somewhat like Active Record just not active or persistence (each app instance had it's own data handling part). The app has subunits handling different aspects. However as it was setup it loaded everything when started. This creates several problems, for example often it wouldn't be neccesary to load a part unless we were specifically going to work with that part so I wan't some form of lazy loading. Also there was problem with inner persistance because you might create a new object/row in one aspect and perhaps set relation between it and different object but the new object wouldn't appear until the program was restarted. Persistance between instances of the app won't be huge problem because of the small amount of people using the program. While I could solve this now using dirty tricks I would rather refactor the program and do it elegantly, Now the question is how. I know there are several ways and a few come to mind: 1) Each aspect of the program is it's own UserControl that get's reloaded/instanced everytime you navigate to it. This ensures you only load up the data you need and you get some persistancy. DB server located on same LAN and tables are small so that shouldn't be a big problem. Minor drawback is that you would have to remember the state of each aspect so you wouldn't always start at beginners square. 2) Having a ViewModel type object at the base level of the app with lazy loading and some kind of timeout. I would then propegate this object down the visual tree to ensure every aspect is getting it's data from the same instance 3) Semi active record data layer with static load methods. 4) Some other idea What in your opinion is the most practical way in WPF, what does MVVM assume?

    That it seems my blog is more of poor me or pity me or I deserve a job blog.   Hmmm I wont say, I have not wined here as I have used this blog to vent my frustration on the whole out of work thing (lack of money, self worth, family issues and the never end bills coming my way) but, it was also me trying to reach to others in the same boat as well as advertising, hay I am out here, employers.   It was also said, that I don’t have any thing listed here on me, like a cover letter or resume. Well there is but, it was so many months and post ago. Also what I had posted is not current. So here is my most current cover and resume.   Scott L Newman 45219 Dutton Way Callahan, Fl. 32011 To Whom It May Concern: I am really interested in the IT vacancie that you have listed for your company. Maybe I don’t have all the qualifications you want (hold on don’t hit delete yet) yet! But maybe I do, as I have over 20 + years experience in "IT” RIGHT NOW.   Read the rest of my cover and my resume. You will see what my “IT” skills are and it will Show that I can to this work! I can bring to your company along with my, can do attitude, a broad range of skills, including: Certified CompTIA A+, Security+  and Network+ Technician §         2.5 years (NOC) Network experience on large Cisco based Wan – UK to Austria §         20 years experience MIS/DP – Yes I can do IBM mainframes and Tandem  non-stops too §         18 years experience as technical Help Desk support – panicking users, no problem §         18 years experience with PC/Server based system, intranet and internet systems §         10+ years experienced on: Microsoft Office, Windows XP and Data Network Fundamentals (YES I do windows) §         Strong trouble shooting skills for software, hard ware and circuit issues (and I can tell you what kind of horrors I had to face on all of them). §         Very experienced on working with customers on problems – again panicking users, no problem §         Working experience with Remote Access (VPN/SecurID) – I didn’t just study them I worked on/with them §         Skilled in getting info for and creating documentation for Operation procedures (I don’t just wait for them to give it to me I go out and get it. Waiting for info on working applications is, well dumb) Multiple software languages (Hey I have done some programming) And much more experiences in “IT” (Mortgage, stocks and financial information systems experience and have worked “IT” in a hospital) Can multitask, also have ability to adapt to change and learn quickly.

  • career advice for PhD scientist seeking to program?

    - by C SD
    I'm largely a self-taught programmer. In fact, I first started programming about half way through biophysics grad school, and even though I think I've done some pretty nice work, I've never worked as part of a 'serious' development team that had more than one or two other developers (and I wouldn't hesitate to call them equally inexperienced in software development as a profession). After finishing my PhD I applied to Google, on a lark, since I had some confidence in my abilities, if not necessarily my experience, and I was hoping to maybe slip in and absorb all the experience and talent I'd be surrounded with and become productive enough, quickly enough, that they wouldn't immediately regret their decision. I was excited to actually get invited to interview up at Mountain View (this was ~ mid 2008). Overall, my memory of the interview was very positive, but after close to a three month wait (is that normal?) they ended up turning me down. I wasn't too surprised or disappointed (aside from the uncomfortably long wait) given my unusual background and admitted lack of experience. I decided to continue as a postdoc, but focus on improving my skills rather than doing research. I've done about three years of that, and my honest assessment is that I've learned a ton more, but I really need more of a peer group to maintain or accelerate my growth. Google invited me to interview again about eight months ago, and the interview process went even better than the first time around (I thought), though they again declined to give me an offer. I have to admit this second rejection was much more discouraging. They had insisted I interview even after I mentioned to them that a move on my part was unlikely given that I had bought a house, gotten married, etc. since the first interview. I guess I was hoping they'd at least give me an offer that I could parlay into a more conventional, but still interesting, programming position close to home. So here I am, going on my third year out of grad school, a glorified postdoc and I'm starting to get pretty discouraged. Even though I could technically get 'back-on-track' for a career in science, I have been focusing the vast majority of this time on gaining programming experience rather than on research and publications. The problem is, whenever I look, most job listings have requirements that seem impossibly grandiose and I hesitate to apply. That, or the job/project seems incredibly dull. Ironically, applying to Google struck me as less intimidating. I suspect that either most people are just a lot less realistic than I am when it comes to assessing how long it will take for them to get up to speed, or they don't care; my fear is that I'm just woefully unqualified for any interesting, well paying work. IE: I'm confident I could switch fully back into C++ mode with a couple weeks work (I mostly use C,Python,C# daily) but I don't list myself as being 'proficient' in C++ on my CV, or applying for jobs that 'require' such knowledge. The few applications for which I did feel I was a legitimately good match have not elicited a response. I suspect the following things are potential problems with my application/CV and I would like feedback on: I don't have a CS degree. My BS was in biochemistry and molecular biology, my PhD in biophysics. I took a undergrad and grad level CS course at UCSD and completely killed them, but I don't know how to translate that to my CV effectively. I have a PhD, but it's not in CS... I've been debating if I should remove it from my CV, and wether or not it would then be misleading to list at least some of those years as some kind of 'programming' job (in many respects it was). I think there are sometimes strong stigmas associated with 'self-taught' programmers. I am certainly one of those. I even recognize that some of those stigmas hold a hint of truth, but I really do want to be an asset to a team. How do I communicate that even though I have been largely self-directing for ~8 years I can still take marching orders when needed? Do I just say so outright? Should I just become a lot less scrupulous about the whole process? anecdote: I have a friend who applied for positions where he completely fudged his qualifications to get past the first culling. He was much more honest and forthcoming about his actual qualifications when contacted and he still managed to get invited to a couple of interviews and even got some offers. His balls are larger than mine though.

  • BizTalk 2009 - SQL Server Job Configuration

    - by StuartBrierley
    Following the installation of Biztalk Server 2009 on my development laptop I used the BizTalk Server Best Practice Analyser which highlighted the fact that two of the SQL Server Agent jobs that BizTalk relies on were not running successfully.  Upon investigation it turned out that these jobs needed to be configured before they would run successfully. To configure these jobs open SQL Server Management Studio, expand SQL Server Agent > Jobs and double click on the appropriate job.  Select Steps and then edit the appropriate entries. Backup BizTalk Server (BizTalkMgmtDb) This job is comprised of three steps BackupFull, MarkAndBackupLog and ClearBackupHistory. BackupFull exec [dbo].[sp_BackupAllFull_Schedule] ‘d’ /* Frequency */,‘BTS’ /* Name */,‘<destination path>’ /* location of backup files */ The frequency here is set/left as daily The name is left as BTS You must provide a full destination path for the backup files to be stored. There are also two optional parameters: A flag that controls if the job forces a full backup if a partial backup fails A parameter to control the time of day to run the full backup; the default is midnight UTC time For example: exec [dbo].[sp_BackupAllFull_Schedule] ‘d’ /* Frequency */,‘BTS’ /* Name */,‘<destination path>’ /* location of backup files */ , 0, 22 MarkAndBackUpLog exec [dbo].[sp_MarkAll] ‘BTS’ /* Log mark name */,’<destination path>’  /*location of backup files */ You must provide a destination path for the log backups. Optionally you can also add an extra parameter that tells the procedure to use local time: exec [dbo].[sp_MarkAll] ‘BTS’ /* Log mark name */,’<destination path>’  /*location of backup files */ ,1 Clear Backup History exec [dbo].[sp_DeleteBackupHistory] @DaysToKeep=7 This will clear out the instances in the MarkLog table older than 7 days.    DTA Purge and Archive (BizTalkDTADb) This job is comprised of a single step. Archive and Purge exec dtasp_BackupAndPurgeTrackingDatabase 0, --@nLiveHours tinyint, 1, --@nLiveDays tinyint = 0, 30, --@nHardDeleteDays tinyint = 0, null, --@nvcFolder nvarchar(1024) = null, null, --@nvcValidatingServer sysname = null, 0 --@fForceBackup int = 0 Any completed instance that is older than the live days plus live hours will be deleted, as will any associated data. Any data older than the HardDeleteDays will be deleted - this means that those long running orchestration instances that would otherwise never be purged will at some point have their data cleared down while allowing the instance to continue, thus preventing the DTA databse from growing indefinitely.  This should always be greater than the soft purge window. The NVC folder is the path for the backup files, if this is null the job will not run failing with the error : DTA Purge and Archive (BizTalkDTADb) Job failed SQL Server Management Studio, job activity monitor, view history The @nvcFolder parameter cannot be null. Archive and Purge step How long you choose to keep instances in the Tracking Database is really up to you. For development I have set this up as: exec dtasp_BackupAndPurgeTrackingDatabase 0, 1, 30, ’<destination path>’, null, 0 On a live server you may want to adjust these figures: exec dtasp_BackupAndPurgeTrackingDatabase 0, 15, 20, ’<destination path>’, null, 0

  • Build 2012, some thoughts..

    - by Dennis Vroegop
    I think you probably read my rant about the logistics at Build 2012, as posted here, so I am not going into that anymore. Instead, let’s look at the content. (BTW If you did read that post and want some more info then read Nia Angelina’s post about Build. I have nothing to add to that.) As usual, there were good speakers and some speakers who could benefit from some speaker training. I find it hard to understand why Microsoft allows certain people on stage, people who speak English with such strong accents it’s hard for people, especially from abroad, to understand. Some basic training might be useful for some of them. However, it is nice to see that most speakers are project managers, program managers or even devs on the teams that build the stuff they talk about: there was a lot of knowledge on stage! And that means when you ask questions you get very relevant information. I realize I am not the average audience member here, I am regular speaker myself so I tend to look for other things when I am in a room than most audience members so my opinion might differ from others. All in all the knowledge of the speakers was above average but the presentation skills were most of the times below what I would describe as adequate. But let us look at the contents. Since the official name of the conference is Build Windows 2012 it is not surprising most of the talks were focused on building Windows 8 apps. Next to that, there was a lot of focus on Azure and of course Windows Phone 8 that launched the day before Build started. Most sessions dealt with C# and JavaScript although I did see a tendency to use C++ more. Touch. Well, that was the focus on a lot of sessions, that goes without saying. Microsoft is really betting on Touch these days and being a Touch oriented developer I can only applaud this. The term NUI is getting a bit outdated but the principles behind it certainly aren’t. The sessions did cover quite a lot on how to make your applications easy to use and easy to understand. However, not all is touch nowadays; still the majority of people use keyboard and mouse to interact with their machines (or, as I do, use keyboard, mouse AND touch at the same time). Microsoft understands this and has spend some serious thoughts on this as well. It was all about making your apps run everywhere on all sorts of devices and in all sorts of scenarios. I have seen a couple of sessions focusing on the portable class library and on sharing code between Windows 8 and Windows Phone 8. You get the feeling Microsoft is enabling us devs to write software that will be ubiquitous. They want your stuff to be all over the place and they do anything they can to help. To achieve that goal they provide us with brilliant SDK’s, great tooling, a very, very good backend in the form of Windows Azure (I was particularly impressed by the Mobility part of Azure) and some fantastic hardware. And speaking of hardware: the partners such as Acer, Lenovo and Dell are making hardware that puts Apple to a shame nowadays. To illustrate: in Bellevue (very close to Redmond where Microsoft HQ is) they have the Microsoft Store located very close to the Apple Store, so it’s easy to compare devices. And I have to say: the Microsoft offerings are much, much more appealing that what the Cupertino guys have to offer. That was very visible by the number of people visiting the stores: even on the day that Apple launched the iPad Mini there were more people in the Microsoft store than in the Apple store. So, the future looks like it’s going to be fun. Great hardware (did I mention the Nokia Lumia 920? No? It’s brilliant), great software (Windows 8 is in a league of its own), the best dev tools (Visual Studio 2012 is still the champion here) and a fantastic backend (Azure.. need I say more?). It’s up to us devs to fill up the stores with applications that matches this. To summarize: it is great to be a Windows developer. PS. Did I mention Surface RT? Man….. People were drooling all over it wherever I went. It is fantastic :-) Technorati Tags: Build,Windows 8,Windows Phone,Lumia,Surface,Microsoft

  • Part 1 Basic Webtrends REST Examples

    - by GeekAgilistMercenary
    In this entry I just want to cover some examples of how to connect to Webtrends DX Web Services.  The DX Web Services use REST as the architecture, providing simple URI based end points to connect to.  With the Webtrends SDK you can connect to these services with your account information.  Here are the basic steps to retrieve a profile list, the reports from one of those profiles, and then the report you want from that report list. First step is to create a Webtrends User. WebTrends.Sdk.Account.User webtrendsUser = new Account.User(); webtrendsUser.UserName = username; webtrendsUser.Password = password; webtrendsUser.AccountName = account; After you create the Webtrends User, simple request a profile list by getting list of ProfileDefinition Objects. List<WebTrends.Sdk.Profile.ProfileDefinition> profiles = WebTrends.Sdk.Factory.NavigationFactory.BuildListing(webtrendsUser); Next you will want to grab a report based on the profile you are in and your credentials. List<WebTrends.Sdk.Report.ReportDefinition> reports = WebTrends.Sdk.Factory.NavigationFactory.BuildListing(profiles[i], webtrendsUser); In the code above, i would equate to the specific profile you want from the retrieved list of profiles in the profiles list.  The common scenario is that one has pulled the profiles into a drop down, combo, or list box that the user can select.  Then when the user selects the specific profile that profile object can then be used to pull the List of ReportDefinitions. Once we have the report definitions, all sorts of criteria can be added together to query for a specific report.  This is also were things can get a little tricky.  For instance, take a look at the code below. WebTrends.Sdk.Factory.ReportFactory.CreateDimensionalReport( report.ID.ToString(), profiles[i].ID.ToString(), "2010m01", webtrendsUser); The CreateDimensionalReport takes 4 parameters for this particular overload.  The report ID, profile ID, the Webtrends Date Format, and the Webtrends User Object.  There are a number of other overloads available within this factory's method that allow for passing the specific REST URI, and other criteria to retrieve the report of your choice.  In the near future we will be adding some more to this method also, which will provide more flexibility without needing to use the full REST URI. I will have more on this, so all you Coders out there using Webtrends DX Services, I hope this is helpful!  Enjoy. Original Entry
