  • Should I avoid or embrace asking questions of other developers on the job?

    - by T.K.
    As a CS undergraduate, the people around me are either learning or are paid to teach me, but as a software developer, the people around me have tasks of their own. They aren't paid to teach me, and conversely, I am paid to contribute. When I first started working as a software developer co-op, I was introduced to a huge code base written in a language I had never used before. I had plenty of questions, but didn't want to bother my co-workers with all of them - it wasted their time and hurt my pride. Instead, I spent a lot of time bouncing between IDE and browser, trying to make sense of what had already been written and differentiate between expected behavior and symptoms of bugs. I'd ask my co-workers when I felt that the root of my lack of understanding was an in-house concept that I wouldn't find on the internet, but aside from that, I tried to confine my questions to lunch hours. Naturally, there were occasions where I wasted time trying to understand something in code on the internet that had, at its heart, an in-house concept, but overall, I felt I was productive enough during my first semester, contributing about as much as one could expect and gaining a pretty decent understanding of large parts of the product. I was wondering what senior developers felt about that mindset. Should new developers ask more questions to get to speed faster, or should they do their own research for themselves? I see benefits to both mindsets, and anticipate a large variety of responses, but I figure new developers might appreciate your answers without thinking to ask this question.

  • How to keep the trunk stable when tests take a long time?

    - by Oak
    We have three sets of test suites: A "small" suite, taking only a couple of hours to run A "medium" suite that takes multiple hours, usually ran every night (nightly) A "large" suite that takes a week+ to run We also have a bunch of shorter test suites, but I'm not focusing on them here. The current methodology is to run the small suite before each commit to the trunk. Then, the medium suite runs every night, and if in the morning it turned out it failed, we try to isolate which of yesterday's commits was to blame, rollback that commit and retry the tests. A similar process, only at a weekly instead of nightly frequency, is done for the large suite. Unfortunately, the medium suite does fail pretty frequently. That means that the trunk is often unstable, which is extremely annoying when you want to make modifications and test them. It's annoying because when I check out from the trunk, I cannot know for certain it's stable, and if a test fails I cannot know for certain if it's my fault or not. My question is, is there some known methodology for handling these kinds of situations in a way which will leave the trunk always in top shape? e.g. "commit into a special precommit branch which will then periodically update the trunk every time the nightly passes". And does it matter if it's a centralized source control system like SVN or a distributed one like git? By the way I am a junior developer with a limited ability to change things, I'm just trying to understand if there's a way to handle this pain I am experiencing.

  • What's the canonical process for backing up a website?

    - by Walkerneo
    This is going to sound terrible, but bear with me. I currently have a cron job that does a mysql dump, a git add all and commit, and a git push to bitbucket. I set this up almost a year ago, when I didn't know much about git, backups, and general web development and administration. I haven't had the time to fix this and do it properly, but the repo has now grown quite big from accumulating large temporary files from my forum, so now I have to do something and I want to do it properly this time around. What processes do semi-large websites and personal site admins use for backing up server content? Based on what I've learned since I set this up, what I'm currently think of doing is: Making changes on a development domain and committing the code frequently Archiving the entire site after a successful deployment from the development domain Having automatic daily database and user-content backups. I still like the idea of backing up sqldumps with git, though. I know git isn't a backup tool and that this is beyond its purpose, but the textual queries that are exported would be easily managed by git and would save a lot of space in archives.

  • Is there a way to save MS Word document as HTML w/o the ms proprietary stuff?

    - by sequoia mcdowell
    So normally I wouldn't use this feature ("Save as Web Page") but I have large documents from clients they just want put on their site as HTML, and formatting it all by hand seems like a waste of time. I have tried "save as webpage" in Word 2007, but it produces all sorts of bad stuff. To wit: <b style='mso-bidi-font-weight:normal'> <span style="mso-spacerun: yes"> as well as a large block of XML formatting info: <!--[if gte mso 9]><xml> <o:DocumentProperties> <o:Subject> </o:Subject> <o:Author> </o:Author> <o:Keywords> </o:Keywords> ... As I said, formatting it all by hand seems like a waste of time, but the way MS exports currently just has too much cruft. Is there a way to export MS Word doc as html without all this?

  • Any examples of fair mmo games with quick completion

    - by Keith Player
    I'm looking for some example games for inspiration that allow from 10 to a large number of players at a time and can be completed in 10 to 30 minutes. I'm looking for something that would have extremely low bandwidth and not be dependent on chance or luck (i.e one player can't gain an unfair advantage because the computer put them in a better position). Realized on the way home that more clarifications might have been helpful. I'm looking to develop a pay-to-play competition that would allow a large number of players to compete in a relatively short period of time. One way would be to have an mmo that can be completed in 30 minutes, another way would be if you could have 10 person games that finish in under 5 minutes and then have the winners compete against each other until a winner is decided. I'm interested in any genre that would make for a fun/interesting game that doesn't depend on luck, so all players should have the same choice/availability of activities/resources and follow the same rules. Some possible games that could possibly be modified into what I want, would be bztanks (too easy to create a bot), diplomacy (takes too long), risk, some chess like game. I was just wondering if there are other game types to the ones I have been considering.

  • Rendering a DOM across multiple displays

    - by meetamit
    I'm building a data-driven animation with HTML and javascript to run in a web browser. I would like to display it tiled across three 1080p monitors. This essentially yields a viewport that's 5760px wide and 1080px tall. Pretty large. Does anyone have experience setting up something like this? I have many questions below, but any tip would be appreciated: Is it reasonable to expect a DOM to render into such a large viewport size at close to 60fps? I might choose to use canvas, instead of SVG or HTML, but that would yield a giant canvas. Can a canvas with such high resolution be performant? Of course everything depends on the complexity of the graphics I want to render, but I'm looking to remove that factor from this question, so assume I'm asking about a canvas animation that can run at 60fps at 1920x1080 resolution. Would it run roughly as fast at 3 times the width? Would three.js and WebGL be a more proper approach at that resolution? How do you actually cause Chrome or FF to span 3 monitors at full screen? Do I need a 3rd party solution of any kind? Thanks!

  • 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?

  • How would you model an objects representing different phases of an entity life cycle?

    - by Ophir Yoktan
    I believe the scenario is common mostly in business workflows - for example: loan management the process starts with a loan application, then there's the loan offer, the 'live' loan, and maybe also finished loans. all these objects are related, and share many fields all these objects have also many fields that are unique for each entity the variety of objects maybe large, and the transformation between the may not be linear (for example: a single loan application may end up as several loans of different types) How would you model this? some options: an entity for each type, each containing the relevant fields (possibly grouping related fields as sub entities) - leads to duplication of data. an entity for each object, but instead of duplicating data, each object has a reference to it's predecessor (the loan doesn't contain the loaner details, but a reference to the loan application) - this causes coupling between the object structure, and the way it was created. if we change the loan application, it shouldn't effect the structure of the loan entity. one large entity, with fields for the whole life cycle - this can create 'mega objects' with many fields. it also doesn't work well when there's a one to many or many to many relation between the phases.

  • I'm a Subversion geek, why should I consider or not consider Mercurial or Git or any other DVCS?

    - by user2567
    I try to understand the benefits of distributed version control system (DVCS). I found Subversion Re-education and this article by Martin Fowler very useful. Mercurial and others DVCS promote a new way of working on code with changesets and local commits. It prevents from merging hell and other collaboration issues We are not affected by this as I practice continuous integration and working alone in a private branch is not an option, unless we are experimenting. We use a branch for every major version, in which we fix bugs merged from the trunk. Mercurial allows you to have lieutenants I understand this can be useful for very large projects like Linux, but I don't see the value in small and highly collaborative teams (5 to 7 people). Mercurial is faster, takes less disk space and full local copy allows faster logs & diffs operations. I'm not concerned by this either, as I didn't notice speed or space problems with SVN even with very large projects I'm working on. I'm seeking for your personal experiences and/or opinions from former SVN geeks. Especially regarding the changesets concept and overall performance boost you measured. UPDATE (12th Jan): I'm now convinced that it worth a try. UPDATE (12th Jun): I kissed Mercurial and I liked it. The taste of his cherry local commits. I kissed Mercurial just to try it. I hope my SVN Server don't mind it. It felt so wrong. It felt so right. Don't mean I'm in love tonight. FINAL UPDATE (29th Jul): I had the privilege to review Eric Sink's next book called Version Control by Example. He finished to convince me. I'll go for Mercurial.

  • External Full HD monitor and Virtual Desktop Size

    - by Stefan
    I have two FullHD monitors attached to my ATI graphics card [2]. The resolution of both of them is detected properly without any modifications to /etc/X11/xorg.conf. I can run both of them in clone mode. However, when I try to run them next to each other, I got the following error: The selected configuration for displays could not be applied. If tried to fix this according to [1]. My xorg.conf now looks like this: Section "Module" Load "glx" EndSection Section "Screen" Identifier "Default Screen" DefaultDepth 24 SubSection "Display" # The 1088 is the smallest multiple of 32 >= 1088 # see manpages Virtual 1920 1088 EndSubSection EndSection This does not seem to be parsed properly. After restarting X, I cannot set resolutions beyond 1600 or so any more. /var/log/Xorg.0.log gives: [ 15.676] (II) fglrx(0): Not using mode "1920x1080" (width too large for virtual size) [ 15.676] (II) fglrx(0): Not using mode "1680x1050" (width too large for virtual size) Are my modifications syntactically incorrect?

  • How to verify the code that could take a substantial time to compile? [on hold]

    - by user18404
    As a follow up to my prev question: What is the best aproach for coding in a slow compilation environment To recap: I am stuck with a large software system with which a TDD ideology of "test often" does not work. And to make it even worse the features like pre-compiled headers/multi-threaded compilation/incremental linking, etc is not available to me - hence I think that the best way out would be to add the extensive logging into the system and to start "coding in large chunks", which I understand as code for a two-three hours first (as opposed to 15-20 mins in TDD) - thoroughly eyeball the code for a 15 minutes and only after all that do the compilation and run the tests. As I have been doing TDD for a quite a while, my code eyeballing / code verification skills got rusty (you don't really need this that much if you can quickly verify what you've done in 5 seconds by running a test or two) - so I am after a recommendations on how to learn these source code verification/error spotting skills again. I know I was able to do that easily some 5-10 years ago when I din't have much support from the compiler/unit testing tools I had until recently, thus there should be a way to get back to the basics.

  • Is There a Cloud Over OpenWorld?

    - by Tony Berk
    If you have been to OpenWorld in the past, you know it can be overwhelming or at least a bit "large." If this is your first time at OpenWorld, get ready! You are in for a big (or I should say HUGE) treat. The first thing you'll notice when you get to San Francisco is there are a lot of people, buses with "Oracle" posters, large exhibit halls filled with demos, games and tchotchkes from vendors with hot new solutions, and then there are the sessions. Yes, in fact there are over 2000 sessions. How can you possibly sort through 2000 sessions to find the best 20 or so for you? Which are the 1% for you? We will try to help with some insight over the next few weeks.  I'm going start at the highest level. Up in the Clouds! Since I know many people are looking for an update on The Oracle Cloud. We will drill down into the cloud and other topics for CRM and Customer Experience sessions in the next set of posts. Below is a list of some of the Oracle executive keynotes during OpenWorld highlighting The Oracle Cloud and applications related topics (the full list is here). In these sessions you will get details on Oracle's strategy and how Oracle is changing the industry to help our customers be more efficient, effective and innovative.

  • Terrible App Review of the Week&ndash;October 2nd

    - by David Paquette
    As some people know, I have a few apps in the Windows Phone Store.  One of these apps was intended to be a gimmicky app that did NOT really do anything useful.  It was just a funny little app that you probably try it once, then almost immediately uninstall.  To my surprise, this app ended up in some of the Top App lists and actually got a large number of downloads (for the Windows Phone Store).  Along with these downloads came a large number of really terrible and offensive reviews.  People are insulting me and saying awful things that they would never say to someone in person (I hope).  I am ok with this.  I can take the bad reviews and it doesn’t really bother me, but I still think that people are incredibly dis-respectful with their app reviews.  So..I am going to start sharing the best of the worst reviews.  If by chance this is your review, please contact me.  I would love to have a quick chat… Literally THE crappiest app I could of downloaded. You might as well rub dog *** in your eyes..... You'd see more!!! Stan8976   P.S. I am not particularly proud of this app, so I am not going to reveal the name. However, as you see more of these amazing reviews, I think you might be able to guess which app it is.

  • Users can benefit from Session Tracking

    I use to work for a large Dental Plan marketing website a few years ago and they had a large customer-driven website that sold Dental Plans to consumers. Their website started tracking users as soon as they hit their web servers, and then they logged everything they could about the user. There are a lot of benefits for using session tracking for both the user and the website. Users can benefit from session tracking due to the fact that a website can retain pertaining information for the user so that they do not have to re-enter the same information repeatedly. In addition, websites can hold specific items in a cart for each user so that they can pay for all of their  items at once when they are ready to complete their purchases. Websites can also benefit from session tracking because they can determine where a specific user came from and which advertising partner gave them a sale. This information is very useful when deciding on where to spend an advertising budget. There is only one real disadvantage when it comes to session tracking, Users can not really control what is actually tracked by a website. Yes, they can disable cookies and this will help, but that means that no tracking can be done at all. Most sites require users to have cookies enabled in order for users to make purchases or login to their accounts.

  • RequireJS: JavaScript for the Enterprise

    - by Geertjan
    I made a small introduction to RequireJS via some of the many cool new RequireJS features in NetBeans IDE. I believe RequireJS, and the modularity and encapsulation and loading solutions that it brings, provides the tools needed for creating large JavaScript applications, i.e., enterprise JavaScript applications. &amp;amp;lt;span id=&amp;amp;quot;XinhaEditingPostion&amp;amp;quot;&amp;amp;gt;&amp;amp;lt;/span&amp;amp;gt; (Sorry for the wobbly sound in the above.) An interesting comment by my colleague John Brock on the above: One other advantage that RequireJS brings, is called lazy loading of resources. In your first example, everyone one of those .js files is loaded when the first file is loaded in the browser. By using the require() call in your modules, your application will only load the javascript modules when they are actually needed. It makes for faster startup in large applications. You could show this by showing the libraries that are loaded in the Network Monitor window. So I did as suggested: Click the screenshot to enlarge it and notice how the Network Monitor is helpful in the context of RequireJS troubleshooting.

  • Fast, accurate 2d collision

    - by Neophyte
    I'm working on a 2d topdown shooter, and now need to go beyond my basic rectangle bounding box collision system. I have large levels with many different sprites, all of which are different shapes and sizes. The textures for the sprites are all square png files with transparent backgrounds, so I also need a way to only have a collision when the player walks into the coloured part of the texture, and not the transparent background. I plan to handle collision as follows: Check if any sprites are in range of the player Do a rect bounding box collision test Do an accurate collision (Where I need help) I don't mind advanced techniques, as I want to get this right with all my requirements in mind, but I'm not sure how to approach this. What techniques or even libraries to try. I know that I will probably need to create and store some kind of shape that accurately represents each sprite minus the transparent background. I've read that per pixel is slow, so given my large levels and number of objects I don't think that would be suitable. I've also looked at Box2d, but haven't been able to find much documentation, or any examples of how to get it up and running with SFML.

  • Most efficient way to store this collection of moduli and remainders?

    - by Bryan
    I have a huge collection of different moduli and associated with each modulus a fairly large list of remainders. I want to store these values so that I can efficiently determine whether an integer is equivalent to any one of the remainders with respect to any of the moduli (it doesn't matter which, I just want a true/false return). I thought about storing these values as a linked-list of balanced binary trees, but I was wondering if there is a better way? EDIT Perhaps a little more detail would be helpful. As for the size of this structure, it will be holding about 10s of thousands of (prime-1) moduli and associated to each modulus will be a variable amount of remainders. Most moduli will only have one or two remainders associated to it, but a very rare few will have a couple hundred associated to it. This is part of a larger program which handles numbers with a couple thousand (decimal) digits. This program will benefit more from this table being as large as possible and being able to be searched quickly. Here's a small part of the dataset where the moduli are in parentheses and the remainders are comma separated: (46) k = 20 (58) k = 15, 44 (70) k = 57 (102) k = 36, 87 (106) k = 66 (156) k = 20, 59, 98, 137 (190) k = 11, 30, 68, 87, 125, 144, 182 (430) k = 234 (520) k = 152, 282 (576) k = 2, 11, 20, 29, 38, 47, 56, 65, 74, ...(add 9 each time), 569 I had said that the moduli were prime, but I was wrong they are each one below a prime.

  • Very basic beginner Ruby question to do with elsif and ranges [migrated]

    - by MattKneale
    I've been trying to get to grasps with Ruby (for all of an hour) and this is my first language. I've got the following code: var_comparison = 5 print "Please enter a number: " my_num = Integer(gets.chomp) if my_num > var_comparison print "You picked a number greater than 5!" elsif my_num < var_comparison print "You picked a number less than 5!" elsif my_num > 99 print "Your number is too large, man." else print "You picked the number 5!" end Clearly the interpreter has no way of distinguishing between accepting the rule 5 or 99. How do I make it so that any number between 6-99 returns "You picked a number greater than 5!", but a number 100 or greater returns "Your number is too large, man!"? Do I need to specifically state a range somehow? How would I best do that? Would it by the normal range methods e.g. if my_num 6..99 or if my_num.between(6..99) ?

  • Using Bulk Operations with Coherence Off-Heap Storage

    - by jpurdy
    Some NamedCache methods (including clear(), entrySet(Filter), aggregate(Filter, …), invoke(Filter, …)) may generate large intermediate results. The size of these intermediate results may result in out-of-memory exceptions on cache servers, and in some cases on cache clients. This may be particularly problematic if out-of-memory exceptions occur on more than one server (since these operations may be cluster-wide) or if these exceptions cause additional memory use on the surviving servers as they take over partitions from the failed servers. This may be particularly problematic with clusters that use off-heap storage (such as NIO or Elastic Data storage options), since these storage options allow greater than normal cache sizes but do nothing to address the size of intermediate results or final result sets. One workaround is to use a PartitionedFilter, which allows the application to break up a larger operation into a number of smaller operations, each targeting either a set of partitions (useful for reducing the load on each cache server) or a set of members (useful for managing client result set sizes). It is also possible to return a key set, and then pull in the full entries using that key set. This also allows the application to take advantage of near caching, though this may be of limited value if the result is large enough to result in near cache thrashing.

  • Salary Negotiation; How Best to Broach the Subject? [closed]

    - by Ed S.
    So I have an upcoming performance review / salary increase and I am at a point in which I believe I will need to negotiate a larger raise than what is to be proposed. As I suspect this may be the case I have been reading as much information on the subject (negotiation) as possible. I work for a great company and fortunately I work under some really talented and reasonable managers. Unfortunately, I am not sure how best to bring up the subject. I don't want to sound greedy and I don't want to start off on the wrong foot. For the sake of argument, assume that I am actually worth more than I am being paid at the moment and I would like to make a counter offer for a relatively large increase (say, boss says 4%, I would like to counter with 15%. I know that seems very large, but I believe I have a case for it.) My question to you, those who are/have been on the other side of this scenario, is how should I start the conversation? What approach would make you most receptive to my plea? I've never negotiated before and I just don't want to start off on the wrong foot. My direct manager is a very straightforward individual, so sugarcoating is not necessary here, but at the same time, I don't want to seem overly aggressive or demanding. Thanks in advance for any advice you can offer.

  • When to open source a project under development? [closed]

    - by QuasarDonkey
    Possible Duplicate: Is it OK to push my code to GitHub while it is still in early development? I've been working on a hobby project for a few months now; it's clocking in at over 15000 source lines of code. A number of people have expressed interest in joining development, and I have full intentions of going open source, since it would not be feasible for me to complete the project alone. I'm just not sure when to open-source it. For context, I've notice many successful open source projects, such as the Linux kernel, had considerable work done before they were open-sourced. In my case, I'd been planning on open-sourcing it after I complete all the underlying libraries and overall architecture. Is this a mistake; should I just release it right now? I'm worried that since certain critical underlying components haven't been finalized, if people build a large codebase around them, it will be very difficult to change or fix things later. On the other hand, it's a very large project that will require multiple developers to complete in a reasonable time. So when is the right time during development to go open source? Preferably, I'd like to hear from some folks who have started their own projects.

  • I am being paid very little(imo), how can I change this? [migrated]

    - by LagWagon
    I am a web developer with about 4 years of relevant work experience in my field. Recently, I went from making $30/hr working from home contracting for large companies to a full time job that only pays 40k/yr. The company I work for now is great, nice people, but a little behind the times. I joined on with very little experience in SQL development but they put me in charge of querying the DB and making reports right away, so I had to go in head first and pick up that skill right away. Which is great, I'm happy I learned more of that, and really make good time when doing SQL now. However, I'm now doing most of their advanced SQL stuff. The day I started, another employee who was running a MVC project based in Yii (which is the sole item that makes this company software) put in his two weeks. Two weeks later, I'm the only one who knows how to use, access, modify, or update this project. Its quite a large responsibility for an "entry level dev", no? I am doing highly advanced jQuery for them to modernize their forms, webpages, amongst other things, a skill that I would bet on few Entry levels being able to do as well as me. I may be wrong, but I feel that what I'm making now is not acceptable. We don't have reviews, ever, so I can't just wait for that.. so I was wondering.. do I sound justified in wanting to be paid more, and how can I make this happen?

  • SqlBulkCopy is slow, doesn't utilize full network speed

    - by Alex
    Hi, for that past couple of weeks I have been creating generic script that is able to copy databases. The goal is to be able to specify any database on some server and copy it to some other location, and it should only copy the specified content. The exact content to be copied over is specified in a configuration file. This script is going to be used on some 10 different databases and run weekly. And in the end we are copying only about 3%-20% of databases which are as large as 500GB. I have been using the SMO assemblies to achieve this. This is my first time working with SMO and it took a while to create generic way to copy the schema objects, filegroups ...etc. (Actually helped find some bad stored procs). Overall I have a working script which is lacking on performance (and at times times out) and was hoping you guys would be able to help. When executing the WriteToServer command to copy large amount of data ( 6GB) it reaches my timeout period of 1hr. Here is the core code for copying table data. The script is written in PowerShell. $query = ("SELECT * FROM $selectedTable " + $global:selectiveTables.Get_Item($selectedTable)).Trim() Write-LogOutput "Copying $selectedTable : '$query'" $cmd = New-Object Data.SqlClient.SqlCommand -argumentList $query, $source $cmd.CommandTimeout = 120; $bulkData = ([Data.SqlClient.SqlBulkCopy]$destination) $bulkData.DestinationTableName = $selectedTable; $bulkData.BulkCopyTimeout = $global:tableCopyDataTimeout # = 3600 $reader = $cmd.ExecuteReader(); $bulkData.WriteToServer($reader); # Takes forever here on large tables The source and target databases are located on different servers so I kept track of the network speed as well. The network utilization never went over 1% which was quite surprising to me. But when I just transfer some large files between the servers, the network utilization spikes up to 10%. I have tried setting the $bulkData.BatchSize to 5000 but nothing really changed. Increasing the BulkCopyTimeout to an even greater amount would only solve the timeout. I really would like to know why the network is not being used fully. Anyone else had this problem? Any suggestions on networking or bulk copy will be appreciated. And please let me know if you need more information. Thanks. UPDATE I have tweaked several options that increase the performance of SqlBulkCopy, such as setting the transaction logging to simple and providing a table lock to SqlBulkCopy instead of the default row lock. Also some tables are better optimized for certain batch sizes. Overall, the duration of the copy was decreased by some 15%. And what we will do is execute the copy of each database simultaneously on different servers. But I am still having a timeout issue when copying one of the databases. When copying one of the larger databases, there is a table for which I consistently get the following exception: System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. It is thrown about 16 after it starts copying the table which is no where near my BulkCopyTimeout. Even though I get the exception that table is fully copied in the end. Also, if I truncate that table and restart my process for that table only, the tables is copied over without any issues. But going through the process of copying that entire database fails always for that one table. I have tried executing the entire process and reseting the connection before copying that faulty table, but it still errored out. My SqlBulkCopy and Reader are closed after each table. Any suggestions as to what else could be causing the script to fail at the point each time?
