• Post build events using ROBOCOPY instead of XCOPY

  - by Vizioz Limited

  I don't know about you, but for a long time I have used XCOPY statements in my Visual Studio post build events to copy my Umbraco files from the project folders to the local version of the website associated with the project.For the last few months we have been building a website framework for a client, who has subsequently sold the site to 5 clients, each with a different skin and some variations in their functional requirements.So, we now have a single source solutions, that builds and copies the site files into 5 seperate local websites, which enables us to easily test them all, what we had found was that this process was starting to slow up our build process and was reaching 30-45 seconds on a high spec Quad core machine (and slower on others)Today I asked Colin to create seperate Solution Configurations within Visual Studio so that while we were developing we could target a single site, and when we wanted to test all sites, we could target "ALL" and the Post Build script would then copy the files to all sites.This worked well, and with a couple of other optimisations, our build was now taking about 10 seconds for a single site.Then Colin came across ROBOCOPY and suggested that maybe this would be a suitable alternative to XCOPY, well, I had not heard of it.. (shock horror some of you shout, some I am sure like me, are also wondering what it is!)ROBOCOPY is new in Windows Vista & Windows 7 (you can also download it for XP & Windows 2003) and it has a lot of additional features, the two that were most interesting to us were:/MIR = Mirror a folder tree/XD = Exclude Directories/NP = No Progress (i.e. it does not give you a chart of it's results, which just fills up your Output window!)So, we set about implementing ROBOCOPY, we decided to use the /MIR switch on all folders that we knew were always stored in our project folders:- images- css- masterpages- xsltAnd for other files we just used the straight robocopy functionality.We also decided to exclude all the .SVN directories using the /XD switch and finally we added the /NP switch as mentioned above.The beauty of all of this, is the /MIR functionality, as this means that only files that have changed will be copied across which greatly speeds up the process, especially on the images folders which previously copied across on every build, now, if we add a new image to the project it will be copied across automatically and then never again, unless we change it of course!The build time now for all sites is approximately 4 seconds and for a single site, 2 seconds, I would highly recommend the time to make the same optimisations to your build processes if you have not done so already.

• Letöltheto az Oracle Database Firewall 5.0

  - by Lajos Sárecz

  2010 május 20-án jelentettük be, hogy megvettük az adatbázis tuzfal megoldást fejleszto Secerno céget. Azóta viszonylag keveset lehetett hallani errol a termékrol, idehaza egyedül az oszi ITBN konferencián tartott róla eloadást Stuart Sharp szuk fél órában. Ráadásul a felvásárlás óta a terméket sem lehetett megvásárolni, hiszen a merge után folyó fejlesztések még nem voltak készen. Január 11. óta azonban letötlheto az Oracle Database Firewall 5.0 telepítoje az Oracle edelivery oldaláról az Oracle Database Product Pack-en belül Linux x86 platformra. A Database Firewall az adatbázis védelem elso vonalának tekintheto. Valós idoben monitorozza az adatbázis aktivitását a hálózaton. SQL nyelvi elemzojével rendkívül pontosan képes detektálni a külso és belso támadásokat, a jogosultatlanul, támadó szándékkal végrehajtott tranzakciókat. Az SQL nyelvi elemzojének kifinomultsága lehetové teszi a szurés közel 100%-os pontosságát és megbízhatóságát, ami azért rendkívül fontos, mert nem elég minden támadó tranzakciót kiszurni, de fontos hogy a normál üzletmenetnek megfelelo tranzakciók közül egyet se szurjön, hiszen az is komoly üzleti károkat okozhat. Az adatbázis tuzfalról több részletet tudhat meg mindenki, aki regisztrál és ellátogat a január 27-i Oracle Security Summit rendezvényünkre, ahol a tervek szerint ismét Stuart Sharp tart majd eloadást, viszont ezúttal 1 órában sokkal több részletet tud megosztani a magyar ügyfelekkel és partnerekkel. A Database Firewall eloadást megelozoen egyébként én tartok egy kb. félórás áttekintést az Oracle Database biztonsági megoldásairól.

• New version of SQL Server Data Tools is now available

  - by jamiet

  If you don’t follow the SQL Server Data Tools (SSDT) blog then you may not know that two days ago an updated version of SSDT was released (and by SSDT I mean the database projects, not the SSIS/SSRS/SSAS stuff) along with a new version of the SSDT Power Tools. This release incorporates a an updated version of the SQL Server Data Tier Application Framework (aka DAC Framework, aka DacFX) which you can read about on Adam Mahood’s blog post SQL Server Data-Tier Application Framework (September 2012) Available. DacFX is essentially all the gubbins that you need to extract and publish .dacpacs and according to Adam’s post it incorporates a new feature that I think is very interesting indeed: Extract DACPAC with data – Creates a database snapshot file (.dacpac) from a live SQL Server or Windows Azure SQL Database that contains data from user tables in addition to the database schema. These packages can be published to a new or existing SQL Server or Windows Azure SQL Database using the SqlPackage.exe Publish action. Data contained in package replaces the existing data in the target database. In short, .dacpacs can now include data as well as schema. I’m very excited about this because one of my long-standing complaints about SSDT (and its many forebears) is that whilst it has great support for declarative development of schema it does not provide anything similar for data – if you want to deploy data from your SSDT projects then you have to write Post-Deployment MERGE scripts. This new feature for .dacpacs does not change that situation yet however it is a very important pre-requisite so I am hoping that a feature to provide declaration of data (in addition to declaration of schema which we have today) is going to light up in SSDT in the not too distant future.

• Picking a code review tool

  - by marcog

  We are a startup looking to migrate from Fogbugz/Kiln to a new issue tracker/code review system. We are very happy with Jira, especially the configurability, but we are undecided on a code review tool. We have been trialing Bitbucket, but it doesn't fit our workflow well. Here are the problems we have identified with BB: Comments can be hard to find: when commenting on code not visible in the diff when code that is commented on is later changed viewing the full file doesn't include comments (also doesn't show changes) Viewing comments on individual commits can be a pain We have the implementer merge the diff and close the issue, whereas pull requests are more suited to the open source model where someone with commit rights merges We would like to automate creation of the code review (either from Jira or a command line tool) No syntax highlighting Once the pull request exceeds a certain size, BB won't show the whole thing and you have to view individual commits Linking BB pull requests to Jira issues is a bit janky: we have a pull request URL field on Jira, but this doesn't work when there are changes in multiple repositories Does anyone have any good suggestion given the above? We are tight on budget, and Jira integration is a big plus. We also have multiple commits per issue, and would like to have the option of viewing individual commits in the review. It might also be worth noting that we have a separate reviewer and tester for each issue.

• Help with a simple incremental backup script

  - by Evan

  I'd like to run the following incomplete script weekly in as a cron job to backup my home directory to an external drive mounted as /mnt/backups #!/bin/bash # TIMEDATE=$(date +%b-%d-%Y-%k:%M) LASTBACKUP=pathToDirWithLastBackup rsync -avr --numeric-ids --link-dest=$LASTBACKUP /home/myfiles /mnt/backups/myfiles$TIMEDATE My first question is how do I correctly set LASTBACKUP to the the the directory in /backs most recently created? Secondly, I'm under the impression that using --link-desk will mean that files in previous backups will not will not copied in later backups if they still exist but will rather symbolically link back to the originally copied files? However, I don't want to retain old files forever. What would be the best way to remove all the backups before a certain date without losing files that may think linked in those backups by currents backups? Basically I'm looking to merge all the files before a certain date to a certain date if that makes more sense than the way I initially framed the question :). Can --link-dest create hard links, and if so, just deleting previous directories wouldn't actually remove linked file? Finally I'd like to add a line to my script that compresses each newly created backup folder (/mnt/backups/myfiles$TIMEDATE). Based on reading this question, I was wondering if I could just use this line gzip --rsyncable /backups/myfiles$TIMEDATE after I run rsync so that sequential rsync --link-dest executions would find already copied and compressed files? I know that's a lot, so many thanks in advance for your help!!

• How Can I Install LibreOffice Base?

  - by Rob

  Useful info: I have tried running sudo dpkg --configure -a and sudo apt-get install -f with no result. I am running Kubuntu 11.10 (the updater is far too unreliable to ever be trusted with performing a version upgrade) The rest of LibreOffice seems to work fine (apart from an annoying bug where tooltips are shown as black text on black background...) I have need to use LibreOffice Base to complete a mail merge document. However, I noticed it's not installed. When I go to install it however... rob@hydrogen:~$ sudo apt-get install libreoffice-base [sudo] password for rob: Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies. libreoffice-base : Depends: libreoffice-core (= 1:3.4.4-0ubuntu1) but it is not going to be installed Depends: libreoffice-base-core (= 1:3.4.4-0ubuntu1) but it is not going to be installed Depends: libreoffice-java-common (>= 1:3.4.4~) but it is not going to be installed Suggests: libmyodbc but it is not going to be installed or odbc-postgresql but it is not going to be installed or libsqliteodbc but it is not going to be installed or tdsodbc but it is not going to be installed or mdbtools but it is not going to be installed Suggests: libreoffice-gcj but it is not installable Suggests: libreoffice-report-builder but it is not going to be installed E: Unable to correct problems, you have held broken packages.

• Git: Fixing a bug affecting two branches

  - by Aram Kocharyan

  I'm basing my Git repo on http://nvie.com/posts/a-successful-git-branching-model/ and was wondering what happens if you have this situation: Say I'm developing on two feature branches A and B, and B requires code from A. The X node introduces an error in feature A which affects branch B, but this is not detected at node Y where feature A and B were merged and testing was conducted before branching out again and working on the next iteration. As a result, the bug is found at node Z by the people working on feature B. At this stage it's decided that a bugfix is needed. This fix should be applied to both features, since the people working on feature A also need the bug fixed, since its part of their feature. Should a bugfix branch be created from the latest feature A node (the one branching from node Y) and then merged with feature A? After which both features are merged into develop again and tested before branching out? The problem with this is that it requires both branches to merge to fix the issue. Since feature B doesn't touch code in feature A, is there a way to change the history at node Y by implementing the fix and still allowing the feature B branch to remain unmerged yet have the fixed code from feature A? Mildly related: Git bug branching convention

• Nervous about the "real" world

  - by Randy

  I am currently majoring in Computer Science and minoring in mathematics (the minor is embedded in the major). The program has a strong C++ curriculum. We have done some UNIX and assembly language (not fun) and there is C and Java on the way in future classes that I must take. The program I am in did not use the STL, but rather a STL-ish design that was created from the ground up for the program. From what I have read on, the STL and what I have taken are very similar but what I used seemed more user friendly. Some of the programs that I had to write in C++ for assignments include: a password server that utilized hashing of the passwords for security purposes, a router simulator that used a hash table and maps, a maze solver that used depth first search, a tree traveler program that traversed a tree using levelorder, postorder, inorder, selection sort, insertion sort, bit sort, radix sort, merge sort, heap sort, quick sort, topological sort, stacks, queues, priority queues, and my least favorite, red-black trees. All of this was done in three semesters which was just enough time to code them up and turn them in. That being said, if I was told to use a stack to convert an equation to infix notation or something, I would be lost for a few hours. My main concern in writing this is when I graduate and land an interview, what are some of the questions posed to assess my skills? What are some of the most important areas of computer science that are prevalent in the field? I am currently trying to get some ideas of programs I can write in C++ that interest and challenge me to keep learning the language. A sodoku solver came to mind but am lost as to where to start. I apologize for the rant, but I'm just a wee bit nervous about the future. Any tips are appreciated.

• Code review “on a napkin” — could it be useful?

  - by gaRex

  Preconditions Team uses DVCS IDE supports comments parsing (like TODO and etc.) Tools like CodeCollaborator are expensive for budget Tools like gerrit are too complex for install or not usable Workflow Author publishes somewhere on central repo feature branch Reviewer fetch it and start review In case of some question/issue reviewer create comment with special label, like "BLA". Such label MUST not be in production code -- only on review stage: $somevar = 123; // BLA Why do echo this here? echo $somevar; When reviewer finish post comments -- it just commits with stupid message "comments" and pushes back Author pulls feature branch back and answer comments in similar way or improve code and push it back When "BLA" comments have gone we can think, that review has successfully finished. Author interactively rebases feature branch, stashes it to remove those "comment" commits and now is ready to merge feature to develop or make any action that usualy could be after successful internal review IDE support I know, that custom comment tags are possible in eclipse & netbeans. Sure it also should be in blablaStorm family. So my specific questions are Do you think this methodology is viable? Do you know something similar? What can be improved in it? ps: migrated from http://stackoverflow.com/questions/12692695/code-review-on-a-napkin-could-it-be-useful

  @lucasjellema: Book review -- Getting Started With Oracle SOA Suite 11g R1: A Hands-On Tutorial "I have to confess that I may be biased – or at least that I have a personal stake in books about the SOA Suite. I am currently in the final stages of writing the Oracle SOA Suite 11g Handbook, published by Oracle Press (see http://www.mhprofessional.com/product.php?isbn=0071608974 and http://wiki.oracle.com/page/Oracle+11g+SOA+Suite+Handbook for some supporting material and early screenshots) which you could consider a competitor to the book I am discussing here. I would suggest however that the two are quite complementary: after reading the Getting Started With Oracle SOA Suite 11g R1: A Hands-On Tutorial and concluding that you want to learn more and delve deeper into the SOA Suite and the concepts around it, it would make perfect sense to read my book, Oracle SOA Suite 11g Handbook, as that takes you to the next level." -- Oracle ACE Director Lucas Jellema of Amis Technology (tags: oracle otn oracleace soa bookreview soasuite) Terri Noyes: The Scoop: Oracle E-Business Suite Support on 64-bit Linux Terri Noyes addresses frequently asked questions about Oracle E-Business Suite (EBS) 64-bit Linux support.

• Improving the performance of a db import process

  - by mmr

  I have a program in Microsoft Access that processes text and also inserts data in MySQL database. This operation takes 30 mins or less to finished. I translated it into VB.NET and it takes 2 hours to finish. The program goes like this: A text file contains individual swipe from a corresponding person, it contains their id, time and date of swipe in the machine, and an indicator if it is a time-in or a time-out. I process this text, segregate the information and insert the time-in and time-out per row. I also check if there are double occurrences in the database. After checking, I simply merge the time-in and time-out of the corresponding person into one row only. This process takes 2 hours to finished in VB.NET considering I have a table to compare which contains 600,000+ rows. Now, I read in the internet that python is best in text processing, i already have a test but i doubt in database operation. What do you think is the best programming language for this kind of problem? How can I speed up the process? My first idea was using python instead of VB.NET, but since people here telling me here on SO that this most probably won't help I am searching for different solutions.

• Switching website DNS with minimal downtime

  - by Gavin

  I need to change my domain's DNS, but here in Thailand the ISPs don't follow any standards for renewing their cache of records, so it can take the full two days. I have a new website with about 1,000 members currently who are sending messages and uploading photos. I don't want both sites on the old and new server running at the same time because then I'd have to manually merge the database and transfer uploaded photos. It would be a huge pain. Both servers also a unique URL from my host, e.g. website12345.hostingcompany.com (old host) and website67890.hostingcompany.com (new host). I don't have much experience with this, but I think what I can do is on www.mysite.com, use .htaccess to do a masked redirect to the new server's URL (website67890.hostingcompany.com). Is it possible to do this and keep all URLs being masked? For example, www.mysite.com/profile/username will actually be loading website12345.hostingcompany.com/profile/username. From Google searches it sounds like this is possible, but I don't understand why this is possible due to security issues, since what's keeping people from masking their site to URLs like facebook.com? I could really use some advice here! Thanks!

• This update does not come from a source that supports changelogs

  - by blade19899

  When I get an update via update-manager for a software like blender/vlc, I like to see what has been fixed/changed. I added the ppa for blender/vlc (this only applies to the software I added a ppa for) sudo add-apt-repository ppa:cheleb/blender-svn sudo apt-get update sudo apt-get install blender And vlc like this. sudo add-apt-repository ppa:videolan/stable-daily sudo apt-get update sudo apt-get install vlc And when i run update-manager, or update manager pop-ups I see that vlc/blender have updates but, I can't see what has been changed/fixed this is the message I get, the screenshot below is for mupen but it's the same thing. (I updated vlc and blender, didn't wanna wait for the next update) This update does not come from a source that supports changelogs. (by the way I have a dutch Ubuntu, so the above text i Google translated it!) It only shows which version you have and to which version you be upgrading to. So my question is, how do I get the change-log tab of update-manager working. if it's even possible?

Such label MUST not be in production code -- only on review stage: $somevar = 123; // REV Why do echo this here? echo $somevar; When reviewer finish post comments -- it just commits with stupid message "comments" and pushes back Author pulls feature branch back and answer comments in similar way or improve code and push it back When "REV" comments have gone we can think, that review has successfully finished. Author interactively rebases feature branch, squashes it to remove those "comment" commits and now is ready to merge feature to develop or make any action that usualy could be after successful internal review IDE support I know, that custom comment tags are possible in eclipse & netbeans. Sure it also should be in blablaStorm family. Questions Do you think this methodology is viable? Do you know something similar? What can be improved in it?

• What is a good way to store tilemap data?

  - by Stephen Tierney

  I'm developing a 2D platformer with some uni friends. We've based it upon the XNA Platformer Starter Kit which uses .txt files to store the tile map. While this is simple it does not give us enough control and flexibility with level design. Some examples: for multiple layers of content multiple files are required, each object is fixed onto the grid, doesn't allow for rotation of objects, limited number of characters etc. So I'm doing some research into how to store the level data and map file. This concerns only the file system storage of the tile maps, not the data structure to be used by the game while it is running. The tile map is loaded into a 2D array, so this question is about which source to fill the array from. Reasoning for DB: From my perspective I see less redundancy of data using a database to store the tile data. Tiles in the same x,y position with the same characteristics can be reused from level to level. It seems like it would simple enough to write a method to retrieve all the tiles that are used in a particular level from the database. Reasoning for JSON/XML: Visually editable files, changes can be tracked via SVN a lot easier. But there is repeated content. Do either have any drawbacks (load times, access times, memory etc) compared to the other? And what is commonly used in the industry? Currently the file looks like this: .................... .................... .................... .................... .................... .................... .................... .........GGG........ .........###........ .................... ....GGG.......GGG... ....###.......###... .................... .1................X. #################### 1 - Player start point, X - Level Exit, . - Empty space, # - Platform, G - Gem

• Is there a measure of code rot?

  - by DarenW

  I'm dealing, again, with a messy C++ application, tons of classes with confusing names, objects have pointers into each other and all over, longwinded Boost and STL data types, etc. (Pause and consider your favorite terror of messy legacy code. We probably have it.) The phrase "code rot" oft comes to mind when I work on this project. Is there a quantitative way to measure code rot? I wouldn't expect anything highly meaningful or scientific, since no other measure of code productivity or quality is so fine. I'm not looking for a mere opposite of measures of code quality, but specifically a measure of how many bad things happened after a series of maintenance software "engineers" have had turns hacking at the code. A general measure applying to any language, or many languages, would be great. If there's no such thing, at least for C++, which is a better than average language for creating messes. Maybe something involving a measure of topology of how objects connect during runtime, a count of chunks of commented out code, how mane files a typical variable's usage is scattered over, I don't know... but surely now, a decade into the 21st Century, someone has attempted to define some sort of rot measure. It would be especially interesting to automate a series of svn checkouts, measure the "rottenosity" of each, and plot the decay over time.

• Use 3 monitors w/built-in intel adapter + two old nvidia PCI cards on 10.10?

  - by Kendall Gifford

  I'd like to move from windows with my current workstation. The only thing holding me back is that I have 3 monitors connected to the system and I really take advantage of the real estate when working. I just installed Ubuntu 10.10 on the system and one of the monitors is up and running just fine. This monitor is connected to the built-in Intel adapter. I also have two old nVidia GeForce4 MX 4000 (nv19pl) cards in my two PCI slots with two monitors connected to them respectively. I installed the legacy (and proprietary) nVidia drivers (the nvidia-96 package) that claims to support these old cards. Now the question is how to get X configured to use all adapters (using two different drivers) so I can use all three monitors (and is this even possible)? From what I've read, it looks like I'll have to write an xorg.conf file since the nVidia driver doesn't support the auto-magic configuration supported by other drivers. On this site: http://wiki.ubuntu.com/X/Config it says that on 10.10 I just need to write an xorg.conf "containing only those sections and options that you need to override Xorg's autoconfigurated settings". So, does this mean I can get away with only including the nVidia-specific configuration stuff and all else will get auto-configured? Or, will providing a config with a "Device" section overrule the auto-magic from detecting/using the Intel adapter? I ran the included nvidia-xconfig to generate a basic, nVidia-specific xorg.conf but I'm hesitant to reboot with it in place, suspecting I'll have a screwed up display. Also, is there any way (any tool or command) to generate an xorg.conf from the current, auto-configured running state of an X session? If I have to write a full, complete config, I'd rather start with one that includes everything that's been auto-detected thus far (and merge it with my nVidia version). Anyhow, any info and thoughts are greatly appreciated (as are answers).

• What have you learnt that has a steep learning curve?

  - by Jonathan Khoo

  Recently, I've invested time in learning the intricacies of Git and it has got me thinking about time and learning. (My previous experience with version control systems was only limited use of CVS and SVN.) It took me a whole day's worth of reading to be able to understand the concepts and differences of Git. There are an infinite number of things available for us to learn. Some, more useful than others. I don't know Fortran - I'm relatively young. But looking back at the preceding years of my life, I notice that I'm busier and busier as time goes on. The amount of things I have to get through in a day is increasingly out of my control. It doesn't take a genius to extrapolate that information and realise I'll have even less time in the future - unless I get fired, but I have no strong plans relating to that idea for now. So, given that I have much more time and energy now than I will have in the future: what have you learnt, that has a steep learning curve, that you would possibly recommend to a fellow programmer? Edit: I've stumbled upon the excellent question What programming skills have provided you the best return on investment? and hav realised that my way of approaching how to spend learning time was naive - it doesn't matter if ten useful concepts can be learnt in the time of one if they're worth it.

• LLVM-3.1 libLLVMSupport.a undefined reference to `dladdr'

  - by user91387

  I'm trying to compile using the llvm-3.1 package. I'm running 12.04 x64 (3.2.0-26 kernel) && 12.10 (3.5.0-4) x64 backported llvm-3.1 from quantal, then debian experimental.

• Bridging the gap between developers and testers with VS 2010

  - by Etienne Tremblay

  Hey everyone, I know it’s been an eternity since I blogged but I have so much to do that I unfortunately need to prioritize.  Vincent Grondin and I did a 7h presentation on the new developer and tester tools available in the VS 2010 suite.  It was a blast.  We did it in front of an audience (around 120) and it was taped.  We did it as a play and really didn’t look at the crowd at all we were training each other on the technology. It is now available for anyone that would like to watch it at this location: http://www.devteach.com/ALM-TFS2010-Bridgingthegap.aspx What we covered in the full day event was Migration to TFS 2010 (10h00) 1-Migration of VSS to TFS (20 min.) 2-Automating the Build (Something you can't do with VSS) ( 20 Min.) 3-User story (Real application context for this presentation) (20 min.) 10h00 Pause Manuel Tests by Dev ( 11h30) 4-Adding a tester to the team (Into to MTM) (20 min.) 5-Define tests (what is a white bug) (20 min.) 6-Fix the bug and show Intellitrace and Play back the test (20 min.) 12h15 Lunch Manuel testing for maintenance (13h30) 7- Implement new Feature (web service) and Identify bug with MTM and branch for a production fix and also add a new Build script (20 min.) 8- Fix bug in production branch, Playback tests, merge the change in main branch (20 min.) Manuel testing with the lab manager (14h30) 9- Intro to Lab manager and environment (20 min.) 10- Change build script to deploy to lab and test with web service in lab environment.

• 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.

(x) Dreaming: About... Thinking: Not about chaos in ? direction .... n Anything else that comes to mind n+1 Zilion other stuff i know but i can't remember ... 8 some other stuff i (don't) remember i forgot, give up, delete, lost, said to myself never again, i haven't had time stuff, have on computer stuff but can't find or don't even know i have it on my computer at least 2-3 or more times, stuff I said to myself i'll check later and never checked again for all sort of "perfectly justified" reasons (time, memory, wife :), whatever,...), ... what is the reason i'm asking this?:) 8 and beyond looking forward to see a lot of answers ?

• Best practice with branching source code and application lifecycle

  - by Toni Frankola

  We are a small ISV shop and we usually ship a new version of our products every month. We use Subversion as our code repository and Visual Studio 2010 as our IDE. I am aware a lot of people are advocating Mercurial and other distributed source control systems but at this point I do not see how we could benefit from these, but I might be wrong. Our main problem is how to keep branches and main trunk in sync. Here is how we do things today: Release new version (automatically create a tag in Subversion) Continue working on the main trunk that will be released next month And the cycle repeats every month and works perfectly. The problem arises when an urgent service release needs to be released. We cannot release it from the main trunk (2) as it is under heavy development and it is not stable enough to be released urgently. In such case we do the following: Create a branch from the tag we created in step (1) Bug fix Test and release Push the change back to main trunk (if applicable) Our biggest problem is merging these two (branch with main). In most cases we cannot rely on automatic merging because e.g.: a lot of changes has been made to main trunk merging complex files (like Visual Studio XML files etc.) does not work very well another developer / team made changes you do not understand and you cannot just merge it So what you think is the best practice to keep these two different versions (branch and main) in sync. What do you do?
