  • US GAAP and IFRS Convergence May Be Delayed Even More

    - by Theresa Hickman
    Yesterday, on March 10, the Financial Accounting Standards Board (FASB) met to discuss the changes in financial statement presentation. Over the last six months, the FASB and IASB have been working feverishly to converge US GAAP and IFRS standards to meet the 2011 deadline. In March alone, the standards-setters met eight times. Many people fear that this accelerated pace is compromising the quality of the end product and that maybe they should slow down and do their due diligence. According to WG&L Accounting & Compliance Alert Checkpoint 3/10/2010, (which requires a subscription to view the full article) "Some statement preparers and investors who advise the FASB believe that the process would be better served if it was slowed down so that more attention could be paid to quality." "Should 2011 be looked at as a line in the sand?" asked Joan Amble, executive vice president and corporate comptroller for American Express Co. "We don't think that due process should be compromised for the due date," concurred Lewis Dulitz, vice president of accounting policies and research for medical products supplier Covidien plc. I personally have mixed emotions about this. On one hand, I have been growing impatient with how slow the US has jumped on the IFRS band wagon. On the other hand, being the conservative that I am and knowing this convergence will be costly and disruptive to businesses, I would prefer to be safe than sorry and get it right the first time.

  • How to Transpose Rows and Columns in Excel 2013

    - by Lori Kaufman
    You’ve setup your worksheet with all your row and column headings and you’ve entered all your data. Then, you discover that it would look better if the rows were the columns and the columns were the rows. How do you accomplish this easily? There is an easy way to convert your rows to columns and vice versa using the Transpose feature in Excel. We’ll show you how. Select the cells containing the headings and data you want to transpose. Click Copy or press Ctrl + C. Click in a blank cell on the spreadsheet. This cell will be the top, left corner of the new table of data. Click the down arrow on the Paste button and select Paste Special from the drop-down menu. On the Paste Special dialog box, select the Transpose check box so there is a check mark in the box and click OK. The rows become the columns and the columns become the rows. The original set of data still exists. You can select those cells and delete the headings and data, if desired. Isn’t that a lot easier and faster than retyping all your data?

  • Server freezes at XX:25

    - by Karevan
    We've ordered a 50 euro/month server on hetzner.de, it has debian OS. The problem is that server is freezing in random time of the day and nothing appears in log. Only hardware reboot helps. Part of the log file while it was freezing: Aug 17 22:38:26 Debian-60-squeeze-64-minimal pure-ftpd: ([email protected]) [INFO] New connection from 95.211.120.220 Aug 17 22:38:26 Debian-60-squeeze-64-minimal pure-ftpd: ([email protected]) [INFO] Logout.

No. theres no way to look in server's console right after when it freezes, sadly. Datacenter supporters do not really want to help about that. Server has been installed 30th july, times and dates of freezes are down there: 6 august, 0:25 18 august, 2:27 21 august, 1:25 26 august, 23:26. We decided that freezing around ??:25 isn't a hardware fault, and decided to reinstall the OS. Later, 31 august, our admin backed up all files, reinstalled Debian, and restored the backup. But then, 7 september, server went down again, at 5:05. We thought it was related to Anyone else experiencing high rates of Linux server crashes during a leap second day? and turned ntp off. But then the server went down twice again, 21 september, 17:29 and 24 september, 20:27. I called all linux admins I knew to help with solving it and they said everything is fine about configuring OS and it could be hardware only. But they dont know why it always freezes at XX:25-30. Maybe some of you know about something related to that?

  • SQL SERVER – Function to Round Up Time to Nearest Minutes Interval

    - by pinaldave
    Though I have written more than 2300 blog posts, I always find things which I have not covered earlier in this blog post. Recently I was asked if I have written a function which rounds up or down the time based on the minute interval passed to it. Well, not earlier but it is here today. Here is a very simple example of how one can do the same. ALTER FUNCTION [dbo].[RoundTime] (@Time DATETIME, @RoundToMin INT) RETURNS DATETIME AS BEGIN RETURN ROUND(CAST(CAST(CONVERT(VARCHAR,@Time,121) AS DATETIME) AS FLOAT) * (1440/@RoundToMin),0)/(1440/@RoundToMin) END GO Above function needs two values. 1) The time which needs to be rounded up or down. 2) Time in minutes (the value passed here should be between 0 and 60 – if the value is incorrect the results will be incorrect.) Above function can be enhanced by adding functionalities like a) Validation of the parameters passed b) Accepting values like Quarter Hour, Half Hour etc. Here are few sample examples. SELECT dbo.roundtime1('17:29',30) SELECT dbo.roundtime1(GETDATE(),5) SELECT dbo.roundtime1('2012-11-02 07:27:07.000',15) When you run above code, it will return following results. Well, do you have any other way to achieve the same result? If yes, do share it here and I will be glad to share it on blog with due credit.

  • Project Corndog: Viva el caliente perro!

    - by Matt Christian
    During one of my last semesters in college we were required to take a class call Computer Graphics which tried (quite unsuccessfully) to teach us a combination of mathematics, OpenGL, and 3D rendering techniques.  The class itself was horrible, but one little gem of an idea came out of it.  See, the final project in the class was to team up and create some kind of demo or game using techniques we learned in class.  My friend Paul and I teamed up and developed a top down shooter that, given the stringent timeline, was much less of a game and much more of 3D objects floating around a screen. The idea itself however I found clever and unique and decided it was time to spend some time developing a proper version of our idea.  Project Corndog as it is tentatively named, pits you as a freshly fried corndog who broke free from the shackles of fair food slavery in a quest to escape the state fair you were born in.  Obviously it's quite a serious game with undertones of racial prejudice, immoral practices, and cheap food sold at high prices. The game itself is a top down shooter in the style of 1942 (NES).  As a delicious corndog you will have to fight through numerous enemies including hungry babies, carnies, and the corndog serial-killer himself the corndog eating champion!  Other more engaging and frighteningly realistic enemies await as the only thing between you and freedom. Project Corndog is being developed in Visual Studio 2008 with XNA Game Studio 3.1.  It is currently being hosted on Google code and will be made available as an open source engine in the coming months.

  • Searching Your PL/SQL Source with Oracle SQL Developer

    - by thatjeffsmith
    Version 3.2.1 included a few tweaks along with several hundred bug fixes. One of those tweaks was the addition of ‘ALL_SOURCE’ as a selection for the Type drop down in the Find Database Object panel. Scroll ALL the way down to the bottom Searching the database for your code or objects can be expensive. The ALL_SOURCE view comes in pretty handy when I want to demo how to cancel long running queries or the Task Progress panel – did you know you can manage all of your long running queries here? Yeah, don’t run this I pretty much hosed our demo pod at Open World b/c I ran that same query but added an ORDER BY b.TEXT DESC to the query and blew up the TEMP space and filled the primary partition on the image. Fun stuff. Anyways, where was I going with this? Oh yeah, searching ALL_SOURCE can be expensive. So we took it out of the product for awhile. And now it’s back in. If you select the ‘ALL’ field, it doesn’t actually search EVERYTHING, because that would probably be less than helpful. So if you want to search your PL/SQL objects for a scrap or bit of code, use the ‘ALL_SOURCE’ option in v3.2.1 Double-Click on the search results to go to the code you’re looking for. Be careful what you search for. Just like any query, it could take awhile.

  • Low level programming - what's in it for me?

    - by back2dos
    For years I have considered digging into what I consider "low level" languages. For me this means C and assembly. However I had no time for this yet, nor has it EVER been neccessary. Now because I don't see any neccessity arising, I feel like I should either just schedule some point in time when I will study the subject or drop the plan forever. My Position For the past 4 years I have focused on "web technologies", which may change, and I am an application developer, which is unlikely to change. In application development, I think usability is the most important thing. You write applications to be "consumed" by users. The more usable those applications are, the more value you have produced. In order to achieve good usability, I believe the following things are viable Good design: Well-thought-out features accessible through a well-thought-out user interface. Correctness: The best design isn't worth anything, if not implemented correctly. Flexibility: An application A should constantly evolve, so that its users need not switch to a different application B, that has new features, that A could implement. Applications addressing the same problem should not differ in features but in philosophy. Performance: Performance contributes to a good user experience. An application is ideally always responsive and performs its tasks reasonably fast (based on their frequency). The value of performance optimization beyond the point where it is noticeable by the user is questionable. I think low level programming is not going to help me with that, except for performance. But writing a whole app in a low level language for the sake of performance is premature optimization to me. My Question What could low level programming teach me, what other languages wouldn't teach me? Am I missing something, or is it just a skill, that is of very little use for application development? Please understand, that I am not questioning the value of C and assembly. It's just that in my everyday life, I am quite happy that all the intricacies of that world are abstracted away and managed for me (mostly by layers written in C/C++ and assembly themselves). I just don't see any concepts, that could be new to me, only details I would have to stuff my head with. So what's in it for me? My Conclusion Thanks to everyone for their answers. I must say, nobody really surprised me, but at least now I am quite sure I will drop this area of interest until any need for it arises. To my understanding, writing assembly these days for processors as they are in use in today's CPUs is not only unneccesarily complicated, but risks to result in poorer runtime performance than a C counterpart. Optimizing by hand is nearly impossible due to OOE, while you do not get all kinds of optimizations a compiler can do automatically. Also, the code is either portable, because it uses a small subset of available commands, or it is optimized, but then it probably works on one architecture only. Writing C is not nearly as neccessary anymore, as it was in the past. If I were to write an application in C, I would just as much use tested and established libraries and frameworks, that would spare me implementing string copy routines, sorting algorithms and other kind of stuff serving as exercise at university. My own code would execute faster at the cost of type safety. I am neither keen on reeinventing the wheel in the course of normal app development, nor trying to debug by looking at core dumps :D I am currently experimenting with languages and interpreters, so if there is anything I would like to publish, I suppose I'd port a working concept to C, although C++ might just as well do the trick. Again, thanks to everyone for your answers and your insight.

  • Why Mac cannot connect to Iphone?

    - by martin08
    I couldn't always ssh to my iPhone from my Mac. They're both on the same wifi network but sometimes the connection is established, sometimes it failed. From my Mac: $ ssh [email protected] ssh: connect to host 192.168.0.102 port 22: Operation timed out $ ping 192.168.0.102 PING 192.168.0.102 (192.168.0.102): 56 data bytes ping: sendto: No route to host ping: sendto: Host is down ping: sendto: Host is down I enabled SSH on the phone and am sure it can load webpages. So what might be a reason why they cannot connect? Thanks

  • FileOpenPicker/FileSavePicker doesn't allow *.* wildcard file associations

    - by mbrit
    On Twitter, Matthias Jauernig commented that the FileOpenPicker and FileSavePicker doesn't allow *.* wildcard file associations. I was relaxed about this and wrote back that it was related to sandboxing implying it was a "good thing", however as Matthias commented back, perhaps it's not.In Metro-style the sandboxing works that if something gives you a file (e.g. the picker, or a share operation), you can access it regardless of where on the system. If you find the file yourself, you have to declare the type.The reason why I think it's related to sandboxing is because if you work with files programmatically you have to be explicit about the file types. This is to stop malware that you think is only interested in - say .PDF files, scanning and uploading any .EML files that it can find on the machine. It follows then on the pickers that restriction would continue. It allow's the retail store team to validate that an app is likely to behave itself. If it's an app that works with images, locking down the picker so that it can only access image file types makes sense.However Matthias mentioned that he has an app that should allow files of any arbitrary file. That fits more into the "if the user selects it, it must be OK" camp than the "programmatic scanning" camp. So now I'm left wondering why the picker doesn't allow any type to be selected.I think then maybe the decision comes down to simplicity. A lot of the decisions in Metro-style design relate to ideas about "zero intimidation". Allow the user to select any file is too much like Old Windows, and not enough like Reimagined Windows. What happens in Matthias's app if the user selects Explorer.exe as the file he or she wants to work with? I guess it's fine if you expect your user to know what they're doing (Old Windows), but not so fine if you're expecting a three year old to work with it (Reimagined Windows).

  • Apache 2.2.16 + PHP 5.2.14 sometimes causes Apache to not stop properly

    - by ZiggyTheHamster
    Sometimes, Apache decides not to shut down nicely. killall apache2 or kill -9 (apache2 PID here) shuts it down so that it can actually start back up without the port being in use. Other posts seem to indicate that PHP 5.2 might have issues hanging up Apache. I'm using the worker MPM on an x86_64 Gentoo Linux system if that helps. Any other things I should consider hanging up Apache besides PHP? Should I be stopping Apache with /etc/init.d/apache2 gracefulstop instead of /etc/init.d/apache2 stop?

  • Vehicle: Boat accelerating and turning in Unity

    - by Emilios S.
    I'm trying to make a player-controllable boat in Unity and I'm running into problems with my code. 1) I want to make the boat to accelerate and decelerate steadily instead of simply moving the speed I'm telling it to right away. 2) I want to make the player unable to steer the boat unless it is moving. 3) If possible, I want to simulate the vertical floating of a boat during its movement (it going up and down) My current code (C#) is this: using UnityEngine; using System.Collections; public class VehicleScript : MonoBehaviour { public float speed=10; public float rotationspeed=50; // Use this for initialization // Update is called once per frame void Update () { // Forward movement if(Input.GetKey(KeyCode.I)) speed = transform.Translate (Vector3.left*speed*Time.deltaTime); // Backward movement if(Input.GetKey(KeyCode.K)) transform.Translate (Vector3.right*speed*Time.deltaTime); // Left movement if(Input.GetKey(KeyCode.J)) transform.Rotate (Vector3.down*rotationspeed*Time.deltaTime); // Right movement if(Input.GetKey(KeyCode.L)) transform.Rotate (Vector3.up*rotationspeed*Time.deltaTime); } } In the current state of my code, when I press the specified keys, the boat simply moves 10 units/sec instantly, and also stops instantly. I'm not really sure how to make the things stated above, so any help would be appreciated. Just to clarify, I don't necessarily need the full code to implement those features, I just want to know what functions to use in order to achieve the desired effects. Thank you very much.

  • What would you do to improve the working of a small Development team?

    - by Omar Kooheji
    My company is having a reshuffle and I'm applying for my boss' job as he's moved up the ladder. The new role would give me a chance to move our development team into the 21st century and I'd like to make sure that: I can provide sensible suggestions in the interview to get the job so I can fix the team If I get the job I can actually enact some changes to actually improve the lives of the developers and their output. I want to know what I can suggest to improve the way we work, because I think it's a mess but every time I've suggested a change it's been shot down because any time spend implementing the change would be time that isn't spent developing software. Here is the state of play at the moment: My team consists of 3-4 developers (Mainly Java but I do some .Net work) Each member of the team is usually works on 2-3 projects at a time We are each responsible for the entire life cycle of the project from design to testing. Usually only one person works on a project (Although we have the odd project that will have more than one person working on it.) Projects tend to be bespoke to single customer, or are really heavilly reliant on a particular customer environment. We have 2-3 "Products" which we evolve to meet customer requirements. We use SVN for source control We don't do continuous integration (I'd like to start) We use a really basic bug tracker for internal issue tracking (I'd like to move to an issue/task management system) Any changes that bring a sudden dip in revenue generation will probably be rejected, the company isn't structured for development most of the rest of the technical team's jobs can be broken down to install this piece of hardware, configure that piece of hardware and once a job is done it's done and you never have to look at it again. This mentality has crept into development team because it's part of the company culture.

  • How can I make a game like doodlejump XNA c#

    I wanted to know how can I make the background scroll down like doodlejump.

  • Central Ohio Day of .Net 2010 Slides and Files

    - by Brian Jackett
    This weekend I presented my “The Power of PowerShell + SharePoint 2007” session at the Central Ohio Day of .Net conference in Wilmington, OH this weekend.  This is the second year I’ve attended this conference, first time as a presenter.  For those unfamiliar Day of .Net conferences are a one-day conference on all things .NET organized by developers for developers.  These events are usually offered at no cost to anyone interested in .NET development.     The attendees of my session had some great questions and I hope they all got something worthwhile out of it.  Below are my slides and demo scripts (some of which I didn’t have time to demo) along with my sample profiles.  If you have any questions, comments, or feedback feel free to leave comments here or send me an email at [email protected].   Slides and Files SkyDrive link   Technology and Friends Interview Experience     On a side note, any of you familiar with one of my Sogeti co-workers in Detroit David Giard may know that he hosts a web series called Technology and Friends.  After my session David tracked me down and asked to interview me about PowerShell.  I was happy to oblige so we sat down and taped some material.  I don’t know when that interview will be going live, but look for it on www.davidgiard.com.   Conclusion     A big thanks goes out to all of the sponsors, speakers, and attendees for the Central Ohio Day of .Net conference.  Without all of them this conference couldn’t have been possible.  I had a great time at the conference and look forward to coming back next year whether that is as a speaker or attendee.       -Frog Out

  • Dynamic real-time pathfinding with C# and unity

    - by Yakri
    A buddy and I are working on a simple 2D top down arena combat game similar to OpenGLAD (grew up on ye olde GLADIATOR). Thing is, we want to make some substantial deviation from our source of inspiration, including completely destructible/changeable terrain. Like rivers that can be frozen, walls which can be knocked down, etc. As well as letting players and NPC's build new terrain objects, some of which cannot be moved through or seen through. So I'm tasked with creating the AI, starting with pathfinding. Because of all the changeable terrain, we need something that can check to see if the player/other NPC's are in line of sight, and which can then check to find current paths around existing terrain, without getting completely confused by new terrain popping up, and old terrain vanishing, and even capable of breaking through terrain. A lot of that will just be filling in the framework of the feature, but I really just don't know where to start. What I'm really looking for are relevant websites, books, articles, or keywords to google. I just can't quite find a direction to start in, because most pathfinding types we've googled up just won't give us even the most basic level of robustness we need.

    I recently built a server with hypervm and xen, now i know xen from command line, but hypervm ties into our whmcs and so its a requirement, however my question is this, when i build a new o/s template my partition table is gone, and i know why, but i was wondering if anyone has built anything in hypervm for adding in partition tables, so i dont have to reinvent the wheel :). i can do it command line in the created vm with fdisk, and i have tracked down the creation scripts for hypervm but i am unsure if these insert directly into the machine as it looks like a lot of the things it does are externalized and are for xen to assign things like ip address etc.. oh and on an aside when i go in to modify the .cnf file to change the boot disk from cdrom to drive on windows when i boot using hypervm it overwrites my setting again..frustrating as heck, i've been trying to track down where in the code it does this, has anyone else had this problem and if so how did you fix it if you did?

  • Windows 8 + Ubuntu dualboot problem - ubuntu does not load after windows updates

    - by Michal Biros
    I have installed Windows 8 64-bit and Ubuntu 14.04 64-bit in dualboot with EFI mode. Everything worked great. I could run Ubuntu or Windows without any problems. Only one little issue was that Windows locked NTFS partitions when I shut it down. When I clicked on restart button in Windows and started Ubuntu, partitions mounted successfully. But today ... I opened windows and downloaded all available updates. When I wanted to come back to Ubuntu I noticed that grub did not count down seconds to automatic start. After choosing Ubuntu option manually, the OS did not load. Just black screen with white underscore in the upper left corner. Windows is accessible always without such issues. Last time I solved it by reinstalling ubuntu but I dont want to do it each time windows downloads some updates. Have you ever meet such problem, or do you know how to solve it? EDIT Ubuntu boots, but it won't start. It ends on loading screen.

  • Announcement: Oracle Database Appliance 2.4 patch update now available

    - by uwes
    The Oracle Database Appliance 2.4 patch is now available from My Oracle Support (MOS).  If you search for the Oracle Database Appliance 2.4.0.0.0 Kit under Patches it will display the newly uploaded bundles. The patch highlights include: Normal redundancy (double-mirroring) option providing 6TB of usable storage Enhanced Diagnostics - Trace File Analyzer and ODACHK Also, if you review the README, you may see content that says:        "The grid infrastructure and database patching, both are rolling upgradable. During our patching, we patch the node 1 first and when completed, we patch the node 2." I would like to clarify that the 'infrastructure' updates (OS, Firmware, ILOM, etc) will require a  short downtime of the ODA while it is applied.  When you update the grid infrastructure (--gi), the appliance manager verifies that the infrastructure was updated so you cannot just patch the GI without first updating the infrastructure. The high level update patch steps include (but not limited to): Download patch update to your ODA The --infra (infrastructure) is updated and ODA Databases are down and the ODA is/may be rebooted ODA and GI/Databases are restarted Issue the command to update the Grid Infrastructure/databases (The order of the steps are completed automatically and you cannot control when the nodes are brought up and down during the patching) Node 1 -- shutdown databases and GI Node 1 -- patch GI/database Node 1 -- bring up databases and GI Node 2 -- shutdown databases and GI Node 2 -- patch GI/database Node 2 -- bring up databases and GI A replay from Friday's with Sohan on the 2.4 release can be found here.  The PDF of the presentation is here. The Data Sheet, WP, and 2.4 Configurator are available on the ODA OTN site.

  • SQL Server Transaction Marks: Restoring multiple databases to a common relative point

    - by Mladen Prajdic
    We’re all familiar with the ability to restore a database to point in time using the RESTORE WITH STOPAT statement. But what if we have multiple databases that are accessed from one application or are modifying each other? And over multiple instances? And all databases have different workloads? And we want to restore all of the databases to some known common relative point? The catch here is that this common relative point isn’t the same point in time for all databases. This common relative point in time might be now in DB1, now-1 hour in DB2 and yesterday in DB3. And we don’t know the exact times. Let me introduce you to Transaction Marks. When we run a marked transaction using the WITH MARK option a flag is set in the transaction log and a row is added to msdb..logmarkhistory table. When restoring a transaction log backup we can restore to either before or after that marked transaction. The best thing is that we don’t even need to have one database modifying another database. All we have to do is use a marked transaction with the same name in different database. Let’s see how this works with an example. The code comments say what’s going on. USE master GOCREATE DATABASE TestTxMark1GOUSE TestTxMark1GOCREATE TABLE TestTable1( ID INT, VALUE UNIQUEIDENTIFIER) -- insert some data into the table so we can have a starting pointINSERT INTO TestTable1SELECT ROW_NUMBER() OVER(ORDER BY number) AS RN, NULLFROM master..spt_valuesORDER BY RNSELECT *FROM TestTable1GO-- TAKE A FULL BACKUP of the databseBACKUP DATABASE TestTxMark1 TO DISK = 'c:\TestTxMark1.bak'GO USE master GOCREATE DATABASE TestTxMark2GOUSE TestTxMark2GOCREATE TABLE TestTable2( ID INT, VALUE UNIQUEIDENTIFIER)-- insert some data into the table so we can have a starting pointINSERT INTO TestTable2SELECT ROW_NUMBER() OVER(ORDER BY number) AS RN, NEWID()FROM master..spt_valuesORDER BY RNSELECT *FROM TestTable2GO-- TAKE A FULL BACKUP of our databseBACKUP DATABASE TestTxMark2 TO DISK = 'c:\TestTxMark2.bak'GO -- start a marked transaction that modifies both databasesBEGIN TRAN TxDb WITH MARK -- update values from NULL to random value UPDATE TestTable1 SET VALUE = NEWID(); -- update first 100 values from random value -- to NULL in different DB UPDATE TestTxMark2.dbo.TestTable2 SET VALUE = NULL WHERE ID <= 100;COMMITGO     -- some time goes by here -- with various database activity... -- We see two entries for marks in each database. -- This is just informational and has no bearing on the restore itself.SELECT * FROM msdb..logmarkhistory USE masterGO-- create a log backup to restore to mark pointBACKUP LOG TestTxMark1 TO DISK = 'c:\TestTxMark1.trn'GO-- drop the database so we can restore it backDROP DATABASE TestTxMark1GO USE masterGO-- create a log backup to restore to mark pointBACKUP LOG TestTxMark2 TO DISK = 'c:\TestTxMark2.trn'GO-- drop the database so we can restore it backDROP DATABASE TestTxMark2GO -- RESTORE THE DATABASE BACK BEFORE OUR TRANSACTION-- restore the full backup RESTORE DATABASE TestTxMark1 FROM DISK = 'c:\TestTxMark1.bak' WITH NORECOVERY;-- restore the log backup to the transaction markRESTORE LOG TestTxMark1 FROM DISK = 'c:\TestTxMark1.trn' WITH RECOVERY, -- recover to state before the transaction STOPBEFOREMARK = 'TxDb'; -- recover to state after the transaction -- STOPATMARK = 'TxDb';GO -- RESTORE THE DATABASE BACK BEFORE OUR TRANSACTION-- restore the full backup RESTORE DATABASE TestTxMark2 FROM DISK = 'c:\TestTxMark2.bak' WITH NORECOVERY;-- restore the log backup to the transaction markRESTORE LOG TestTxMark2 FROM DISK = 'c:\TestTxMark2.trn' WITH RECOVERY, -- recover to state before the transaction STOPBEFOREMARK = 'TxDb'; -- recover to state after the transaction -- STOPATMARK = 'TxDb';GO USE TestTxMark1-- we restored to time before the transaction -- so we have NULL values in our tableSELECT * FROM TestTable1 USE TestTxMark2-- we restored to time before the transaction -- so we DON'T have NULL values in our tableSELECT * FROM TestTable2   Transaction marks can be used like a crude sync mechanism for cross database operations. With them we can mark our databases with a common “restore to” point so we know we have a valid state between all databases to restore to.

  • Unit testing statically typed functional code

    - by back2dos
    I wanted to ask you people, in which cases it makes sense to unit test statically typed functional code, as written in haskell, scala, ocaml, nemerle, f# or haXe (the last is what I am really interested in, but I wanted to tap into the knowledge of the bigger communities). I ask this because from my understanding: One aspect of unit tests is to have the specs in runnable form. However when employing a declarative style, that directly maps the formalized specs to language semantics, is it even actually possible to express the specs in runnable form in a separate way, that adds value? The more obvious aspect of unit tests is to track down errors that cannot be revealed through static analysis. Given that type safe functional code is a good tool to code extremely close to what your static analyzer understands. However a simple mistake like using x instead of y (both being coordinates) in your code cannot be covered. However such a mistake could also arise while writing the test code, so I am not sure whether its worth the effort. Unit tests do introduce redundancy, which means that when requirements change, the code implementing them and the tests covering this code must both be changed. This overhead of course is about constant, so one could argue, that it doesn't really matter. In fact, in languages like Ruby it really doesn't compared to the benefits, but given how statically typed functional programming covers a lot of the ground unit tests are intended for, it feels like it's a constant overhead one can simply reduce without penalty. From this I'd deduce that unit tests are somewhat obsolete in this programming style. Of course such a claim can only lead to religious wars, so let me boil this down to a simple question: When you use such a programming style, to which extents do you use unit tests and why (what quality is it you hope to gain for your code)? Or the other way round: do you have criteria by which you can qualify a unit of statically typed functional code as covered by the static analyzer and hence needs no unit test coverage?

  • Camera wont stay behind model after pitch, then rotation

    - by ChocoMan
    I have a camera position behind a model. Currently, if I push the left thumbstick making my model move forward, backward, or strafe, the camera stays with the model. If I push the right thumbstick left or right, the model rotates in those directions fine along with the camera rotating while maintaining its position relatively behind the model. But when I pitch the model up or down, then rotate the model afterwards, the camera moves slightly rotates in a clock-like fashion behind the model. If I do a few rotations of the model and try to pitch the camera, the camera will eventually be looking at the side, then eventually the front of the model while also rotating in a clock-like fashion. My question is, how do I keep the camera to pitch up and down behind the model no matter how much the model has rotated? Here is what I got: // Rotates model and pitches camera on its own axis public void modelRotMovement(GamePadState pController) { // Rotates Camera with model Yaw = pController.ThumbSticks.Right.X * MathHelper.ToRadians(angularSpeed); // Pitches Camera around model Pitch = pController.ThumbSticks.Right.Y * MathHelper.ToRadians(angularSpeed); AddRotation = Quaternion.CreateFromYawPitchRoll(Yaw, 0, 0); ModelLoad.MRotation *= AddRotation; MOrientation = Matrix.CreateFromQuaternion(ModelLoad.MRotation); } // Orbit (yaw) Camera around with model (only seeing back of model) public void cameraYaw(Vector3 axisYaw, float yaw) { ModelLoad.CameraPos = Vector3.Transform(ModelLoad.CameraPos - ModelLoad.camTarget, Matrix.CreateFromAxisAngle(axisYaw, yaw)) + ModelLoad.camTarget; } // Raise camera above or below model's shoulders public void cameraPitch(Vector3 axisPitch, float pitch) { ModelLoad.CameraPos = Vector3.Transform(ModelLoad.CameraPos - ModelLoad.camTarget, Matrix.CreateFromAxisAngle(axisPitch, pitch)) + ModelLoad.camTarget; } // Call in update method public void updateCamera() { cameraYaw(Vector3.Up, Yaw); cameraPitch(Vector3.Right, Pitch); } NOTE: I tried to use addPitch just like addRotation but it didn't work...

  • #altnetseattle &ndash; Collaboration, Why is it so hard!

    - by GeekAgilistMercenary
    The session convened and we began a discussion about why collaboration is so hard. To work together in software better us engineers have to overcome traditional software approaches (silos of work) and the human element of tending to go off in a corner to work through an issue. It was agreed upon that software engineers are jack asses of jack assery. Breaking down the stoic & silent types by presenting a continuous enthusiasm until the stoic and silent types break down and open up to the group.  Knowing it is ok to ask the dumb question or work through basic things once in a while. Non-work interactions are pivotal to work related collaboration. Collaboration is mostly autonomous of process (i.e. Agile or Waterfall) Latency time should be minimal in the feedback loop for software development. Collaboration is enhanced by Agile Ideals, and things like Scrum or Lean Process. Agile is not a process, Lean and Scrum are process.  Agile is an ideal. Lean, Agile, Scrum, Waterfall, Six Sigma, CMMI, oh dear. . . Great session.  Off to the next session and more brain crunching. . . weeeeeeee!
