• Minimizing data sent over a webservice call on expensive connection

  - by aceinthehole

  I am working on a system that has many remote laptops all connected to the internet through cellular data connections. The application will synchronize periodically to a central database. The problem is, due to factors outside our control, the cost to move data across the cellular networks are spectacularly expensive. Currently the we are sending a compressed XML file across the wire where it is being processed and various things are done with (mainly stuffing it into a database). My first couple of thoughts were to convert that XML doc to json, just prior to transmission and convert back to XML just after receipt on the other end, and get some extra compression for free without changing much. Another thought was to test various other compression algorithms to determine the smallest one possible. Although, I am not entirely sure how much difference json vs xml would make once it is compressed. I thought that their must be resources available that address this problem from an information theory perspective. Does anyone know of any such resources or suggestions on what direction to go in. This developed on the MS .net stack on windows for reference.

• Is Moving Entity Framework objects over a webservice really the best way?

  - by aceinthehole

  I've inherited a .NET project that has close to 2 thousand clients out in the field that need to push data periodically up to a central repository. The clients wake up and attempt to push the data up via a series of WCF webservices where they are passing each entity framework entity as parameter. Once the service receives this object, it preforms some business logic on the data, and then turns around and sticks it in it's own database that mirrors the database on the client machines. The trick is, is that this data is being transmitted over a metered connection, which is very expensive. So optimizing the data is a serious priority. Now, we are using a custom encoder that compresses the data (and decompresses it on the other end) while it is being transmitted, and this is reducing the data footprint. However, the amount of data that the clients are using, seem ridiculously large, given the amount of information that is actually being transmitted. It seems me that entity framework itself may be to blame. I'm suspecting that the objects are very large when serialized to be sent over wire, with a lot context information and who knows what else, when what we really need is just the 'new' inserts. Is using the entity framework and WCF services as we have done so far the correct way, architecturally, of approaching this n-tiered, asynchronous, push only problem? Or is there a different approach, that could optimize the data use?

• Windows 8 will only recognize the Blu Ray ROM, if the install disk is present at boot time

  - by aceinthehole

  If I have the install disk in the blu ray ROM drive at boot time and subsequently remove the disk and replace it with blu ray media everything functions as I'd expect. However, if I have no media present, or another disk in the drive at boot time, then windows 8 does not seem to recognize that the blu ray player is even present in the computer. It is not present in the 'my computer' screen, device manager does not show the player, and scanning for new hardware yields nothing. It seems that the driver is installed and working as expect, what is it about having the windows 8 install disk in the drive or not that would cause this kind of behavior?

• Windows 8 will only recognize the Blu-Ray drive, if the Windows 8 disc is present at boot time

  - by aceinthehole

  If I have the install disc in the Blu-Ray ROM drive at boot time and subsequently remove the disc and replace it with Blu-Ray media, everything functions as I’d expect. However, if I have no media present, or another disc in the drive at boot time, then Windows 8 does not seem to recognize that the Blu-Ray player is even present in the computer. It is not present in My Computer, the Device Manager does not show the player, and scanning for new hardware yields nothing. It seems that the driver is installed and working as expected, but what is it about having the Windows 8 install disc in the drive or not that would cause this kind of behavior?

• iTunes Over the Air Sync

  - by aceinthehole

  Is there any software or hack in existence that will allow iTunes to sync wirelessly with my iPhone or iPod touch? I'd like the iPhone to be constantly synced without having to plug it into the USB at my computer via the 802.11 connection, or even better I would like it to happen over 3G when I am not at home. I'd heard that is might be possible (albeit slow) but have not been able to find any software or specific steps out anywhere that lets you do it.

• Windows Server 2003 Is there a limit on number of TCP connections per process?

  - by aceinthehole

  We are running into issues with BizTalk host instance intermittently going down. One of the things that we are worried about is the number of FTP connections a single host instance is making which could easily reach into the hundreds perhaps sometimes thousands, depending on traffic. My question is Windows Server 2003 Is there a limit on number of TCP connections per process? If so would putting each application in it's own host instance potentially solve the problem.

• UI Automation in Citrix

  - by aceinthehole

  I would like to be able to use a tool like WatiN to automate somethings that needs to interact with a Web App that is access by using an instance of IE running on Citrix. So far it seems impossible to interact with the window at even a rudimentary level using SendKeys as the internal UI components seemingly do not have a handle. Has anyone been able to do this or anything similar?

• Calling SSIS from BizTalk Orchestration

  - by aceinthehole

  I have a scenario were I need to move a vast amount of data, and I need to use BizTalk to control the flow and contain the business logic. The problem is that BizTalk will not be able to handle the amount of data that needs to be moved. We have decided to a BizTalk Orchestration to kick off an SSIS package that does the actual heavy lifting. However, there is a caveat in that we have to be able to pass information into SSIS such as file location and info about how to split certain data up. My question is, what is the best way to call into SSIS from an Orchestration given those parameters? Should I build a webservice around it? Is there an adapter or stored procedure that I can call? Or is there a way to call it directly from the Orchestration?

• Automatically truncate to MaxLength during mapping

  - by aceinthehole

  I have a schema that has the max length property set on all of its elements, of various size. I am mapping to it and expect that the max length will be exceeded quite often. Is there a way tell BizTalk to automatically truncate without having to go in and manually configure a functoid for each element? Is there a purpose for the max length property other than validation?

• BULK INSERT with inconsitant number of columns

  - by aceinthehole

  I am trying to load a large amount data in SQL server from a flat file using BULK INSERT. However, my file has varying number of column, for instance the first row contains 14 and the second contains 4. That is OK, I just want to make a table with the max number of columns and load the file into it with nulls for the missing columns. I can play with it from that point. But it seems that SQL Server when reaching the end of the line and having more columns to fill for that same row in the destination table, just moves on to the next line and attempts to put the data on that line to the wrong column of the table. Is there a way to get the behavior that I am looking for? Is there a table hint that I can use the specify this? Has anyone run into this before? Here is the code BULK INSERT #t FROM '<path to file>' WITH ( DATAFILETYPE = 'char', KEEPNULLS, FIELDTERMINATOR = '#' )

• Should I learn FLEX, is it a marketable enough?

  - by aceinthehole

  I haven been recently laid off and was considering what to learn in the down time while trying to get another job. I had heard that Adobe's FLEX was starting to become more in-demand, and have seen it increasingly on job postings. Has anyone else been successful (career wise) in learning FLEX? Is it worth spending time to learn FLEX to add a bullet point to a resume, and lead to a possible job or should time be spent else where?

• Removing the Default Wrap Character From all records

  - by aceinthehole

  I am using BizTalk 2009 and I have a flat file that is similar to the following "0162892172","TIM ","LastName ","760 "," ","COMANCHE ","LN " "0143248282","GEORGE ","LastName ","625 "," ","ENID ","AVE " When I parse it and start mapping it I need to get rid of the quotation marks. I have marked the Wrap Character attribute for the schema as a quotation mark but it doesn't remove it when BizTalk is parsing the file. Is there an easy way to specify the removal of a wrap character or am I going to have to run it through a script functiod every time? Also I would like to be able to remove the trailing spaces as well, if at all possible.

• Table Variables in SSIS

  - by aceinthehole

  In one SQL Task can I create a table variable DELCARE @TableVar TABLE (...) Then in another SQL Task or DataSource destination and select or insert into the table variable? The other option I have considered is using a Temp Table. CREATE TABLE #TempTable (...) I would prefer to use Table Variable so that it remains in memory. But can use temp table if it is not possible to use table variable. Also I cannot use the record set destination as I need to preform straight SQL tasks on it later on.
