• Sync version of the project with Java

  - by Alexadar

  I have a problem, I need to sync version of the project. Changes are performed on main project that resides on central Coldfusion server. There are about 30 remote Coldfusion servers, that has to sync with latest version on central server. New synch application will to be done in Java! I have a direct link to each remote location. Mostly Windows OS and Windows tools are used. My idea: The synchronization is performed at the level of synchronization of folders. I would like to avoid the use of SVN and similar tools. My idea is to carry out comparison of folders on the local server (comparison is performed between the old and new versions),with NO communication with remote servers, make the difference between the versions and the same is sent to the remote machines. We will install Tomcat on every remote server. "Sync application" deployed on Tomcat will take care about differences. Remote server will return me an answer, about the success of the sync. Any kind of suggestion or completely new approach on this topic is more than welcome. Thanks Best regards

• HTML relative links on various domains

  - by Adam Kiss

  I have quickie: When you code/develop themes, how do you link to various files in your html/css code? Example: We at our firm use mostly <base target="http://whatever"> in our main template and then just <img src="./images/file.png"> in our html, "/category/page" as links and something alike in our css. However, when testing on different machines, we use ip address rather than localhost on main dev station of coder, so all base links don't work (because localhost goes to viewing machine, not coder's, in our network). Same thing happens when updating pages - on dev server, we have to edit base target, so browsing site won't take us to live site - this part is actually rather simple PHP (if ... echo else echo something else), but it still not solve problem of more coding-testing problems. So, my question is, how do YOU solve it? How do you use relative links, which basically don't care for what domain is the page on and don't care for url rewrite? (because ../images/ is different for / and different for /something/somethingElse/page)?

• Is MarshalByRefObject special?

  - by Vilx-

  .NET has a thing called remoting where you can pass objects around between separate appdomains or even physical machines. I don't fully understand how the magic is done, hence this question. In remoting there are two base ways of passing objects around - either they can be serialized (converted to a bunch of bytes and the rebuilt at the other end) or they can inherit from MarshalByRefObject, in which case .NET makes some transparent proxies and all method calls are forwarded back to the original instance. This is pretty cool and works like magic. And I don't like magic in programming. Looking at the MarshalByRefObject with the Reflector I don't see anything that would set it apart from any other typical object. Not even a weird internal attribute or anything. So how is the whole transparent proxy thing organized? Can I make such a mechanism myself? Can I make an alternate MyMarshalByRefObject which would not inherit from MarshalByRefObject but would still act the same? Or is MarshalByRefObject receiving some special treatment by the .NET engine itself and the whole remoting feat is non-duplicatable by mere mortals?

• Why is UseCompatibleTextRendering needed here?

  - by HotOil

  Hi, I think I'm missing something fundamental. Please tell me what it is, if you can. I have developed a little C++ WinForms app using VS2008. So it is built using .NET 3.5 SP1. My development box is Win7, if that matters. The default value of UseCompatibleTextRendering property in WinForms controls is false in this version of VStudio. And this should not matter to me, I don't think. I don't have any custom-drawn text or controls. The app looks good running on my Win7 box. If I package it up (dragging along .NET 3.5) and install it on one of our WinXP desktops, the buttons and labels don't look good; the text is chopped off in them. If I set UseCompatibleTextRendering to true and then run it on the XP boxes, the text fits into the buttons and labels. My question is: Why? The installation puts .Net 3.5 on the XP boxes, so the app should be able to find and use the right version of WinForms, right? I should note that before I put my app + .NET 3.5 on these boxes, they have no .NET at all. They do not get automatic Microsoft updates; our IT guy gates the patches and upgrades. [ This sort of thing has happened before with apps I create.. they look/work great on the Engineering machines, because we maintain those and they mostly have up-to-date stuff. When they are run on the corporate boxes, they usually don't run and need the VCredist installed. ] Back to the question at hand: The text looks better with the UseCompatibleTextRendering set to false, so I'd rather keep it that way, if I can. I'd like to understand what might be missing on those XP boxes that is making the text not fit. Thanks S

• Command or tool to display list of connections to a Windows file share

  - by BizTalkMama

  Is there a Windows command or tool that can tell me what users or computers are connected to a Windows fileshare? Here's why I'm looking for this: I've run into issues in the past where our deployment team has deployed BizTalk applications to one of our environments using the wrong bindings, leaving us with two receive locations pointing to the same file share (i.e. both dev and test servers point to dev receive location uri). When this occurs, the two environments in question tend to take turns processing the files received (meaning if I am attempting to debug something in one environment and the other environment has picked the file up, it looks as if my test file has disappeared into thin air). We have several different environments, plus individual developer machines, and I'd rather not have to check each individually to find the culprit. I'm looking for a quick way to detect what locations are connected to the share once I notice my test files vanishing. If I can determine the connections that are invalid, I can go directly to the person responsible for that environment and avoid the time it takes to randomly ask around. Or if the connections appear to be correct, I can go directly to troubleshooting where in the process the message gets lost. Any suggestions?

• asp.net 3.5 app - can not load asemblies, "Strong name signature could not be verified", only when d

  - by hitsolutions

  Have developed an asp.net 3.5 application which consists of a we-site, some developed assemblies and some 3rd party assembles such as Telerik, Jayrock etc, all very much standard 3rd party apps. Created and built this app, tested on Win 2008 Eval running on a VM, all fine. Imagine my frustration when after installing on clients production Win 2008 server, that the app could not run and the error message was the "Strong name signature could not be verified. The assembly may have been tampered with, or it was delay signed ..." one. This was for all assembles in app (removed one and this kept popping up for a different assembly). Attempted to install on a machine on the network and received the same error. I am fairly baffled and a little freaked as I can not figure this out and time is rapidly running out. Have inspected all parts of server I know about (.NET, IIS7) but all seems fine. What could cause this? It sounds like there is a stricter security manifest on the production server - but where would I look and for what? It must be a group policy. only other item is that the machines are running Symantec ante-virus. The IT head is on hols so can't quiz him which is also frustrating - but as they say time waits for no man!

• Suggestions on writing a TCP IP messaging system (Client/Server) using Delphi 2010

  - by Shane

  I would like to write a messaging system using TCP IP in Delphi 2010. I would like to hear what my best options are for using the standard delphi 2010 components/indy components for doing this. I would like to write a server which does the listening and forwarding of messages to all machines on the network running a client. 1.) a.) clients can send a message to server to be forwarded to all other clients b.) clients listen for messages from other senders (via server) and displays messages. 2.) a.) Server can send a message to all clients b.) Server forwards any messages from clients to all other clients thanks for any suggestions NOTE: I am not writing a instant messaging or chat program. This is merely a system where users can send alerts/messages to other users - they can not reply to each other! NO commercial, shareware, etc links - please! I would like to hear about how you would go about writing this type of system and what approachs you would take, and possibly the TCP IP messaging architecture you would use. Whether it be straight Winows API, Indy components, etc, etc.

• PHP IDE with Integrated Web Server

  - by seth

  Note: This is not another "What is the best PHP IDE?" question. I'm looking for a PHP IDE with a specific feature, namely an integrated / embedded (php enabled) web server; ideally with xdebug pre-bundled. I already know that Aptana 1.5 has this functionality (and some older versions of Zend Studio as well), but Aptana 1.5 hasn't been supported for quite some time and as we make the transition to PHP 5.3 and beyond, it's usefulness will diminish significantly. I've looked at some options including Eclipse PDT and NetBeans, but it seems every PHP IDE relies on a separate local/remote web server to actually interpret the code. I know installing a web server locally is fairly trivial, but this is for a classroom solution, where installing, configuring, and maintaining a web server on 1000 machines is simply not feasible. A remote server solution will also not work due to the need to use debugging functionality (xdebug currently requires a hardcoded IP for the debug client). This seems like such an obvious feature/plugin for a PHP IDE, but my research thus far has turned up no results.

• Hosting an Access DB

  - by Mitciv

  Hey, So I'm inexperienced in hosting DB's and I've always had the luxury of someone else getting the db setup. I was going to help a friend out with getting a webpage setup, I've got experience in Asp.Net MVC so I'm going with that. They want to setup a search page to query a db and display the results. My question I have is in getting the DB setup and hosted. They currently just have the Access DB on a local computer. There is basically only one table that would need to be queried for the search. What is the best approach to getting this table/db accessible? They would like to keep the main copy of the db on the local machine, so copying the entire db over to the hosted site would be time consuming, could the lone table needed be solely copied to the host? Should I try to convince them to make changes on the hosted db and just make copies of that for their local machines? Any suggestions are welcome, Again I'm a total noob when it comes to hosting databases. Thanks

• Help me understand WebDAV and Autoversioning

  - by Malfist

  I just read the WebDAV Appendex in the O'Reilly Subversion book. I don't quite understand it. It talked about users being able to "mount" WebDAV directories (trees) and manipulate the files like they would normally and on saves the server would automagically create a new revision. The way it explained it, it sounded like it would work for any program, but then at the end of the appendix, it listed a series of programs that worked with WebDAV servers, which leads me to think that maybe it doesn't work like it originally described it. My question is this: How exactly do you interact with a WebDAV repository? Can I do this for example: Copy a file locally via ftp, edit it with notepad++, and then upload it via ftp to the server and have the server do a commit and create a new revision with the file I just edited and uploaded. Also, if that is possible, what happens if two people edit the file locally (on their machines) and uploaded two reversions to the server? With webDAV will I be able to replace Dreamweaver's "Oops, someone edited this before you" with simple ftp uploads and subversion conflict resolutions?

• Can't get node.js built on cygwin

  - by mwt

  Following the instructions here: https://github.com/ry/node/wiki/Building-node.js-on-Cygwin-(Windows) I've tried installing on two machines, either of which I'd be happy to get up and running. WinXP On 'make', I get: Build failed: -> task failed <err #2>: {task: libv8.a SConstruct -> libv8.a} According to the instructions, this is caused by having $SHELL set to a Windows style path, but I've set it to /bin/bash and get the same error. Win7 On './configure', I get: $ ./configure Checking for program g++ or c++ : /usr/bin/g++ Checking for program cpp : /usr/bin/cpp Checking for program ar : /usr/bin/ar Checking for program ranlib : /usr/bin/ranlib Checking for g++ : ok Checking for program gcc or cc : /usr/bin/gcc 0 [main] python 1092 C:\bin\python.exe: *** fatal error - unable to remap \\?\C:\lib\python2.6\lib-dynload\_functools.dll to same address as parent: 0x360000 != 0x3E0000 Stack trace: Frame Function Args 002891E8 6102749B (002891E8, 00000000, 00000000, 00000000) 002894D8 6102749B (61177B80, 00008000, 00000000, 61179977) 0028A508 61004AFB (611A136C, 61241CF4, 00360000, 003E0000) End of stack trace 0 [main] python 3536 fork: child 1092 - died waiting for dll loading, errno 11 /Users/Michael/Desktop/node/wscript:177: error: could not configure a c compiler! I've run 'rebaseall' and restarted the machine but still get that error. Edit: Ok, rebaseall was apparently erroring on some mingw stuff, so I edited the rebaseall script to fix that, and now it configures on Win7. The new problem is that it emits the exact same error as my XP machine now when I try to make. This is on tag v0.3.5.

• An Erroneous SQL Query makes browser hang until script timeout exceeded

  - by Jimbo

  I have an admin page in a Classic ASP web application that allows the admin user to run queries against the database (SQL Server 2000) Whats really strange is that if the query you send has an error in it (an invalid table join, a column you've forgotten to group by etc) the BROWSER hangs (CPU usage goes to maximum) until the SERVER script timeout is exceeded and then spits out a timeout exceeded error (server and browser are on different machines, so not sure how this happens!) I have tried this in IE 8 and FF 3 with the same result. If you run that same query (with errors) directly from SQL Enterprise Manager, it returns the real error immediately. Is this a security feature? Does anyone know how to turn it off? It even happens when the connection to the database is using 'sa' credentials so I dont think its a security setting :( Dim oRS Set oRS = Server.CreateObject("ADODB.Recordset") oRS.ActiveConnection = sConnectionString // run the query - this is for the admin only so doesnt check for sql safe commands etc. oRS.Open Request.Form("txtSQL") If Not oRS.EOF Then // list the field names from the recordset For i = 0 to oRS.Fields.Count - 1 Response.Write oRS.Fields(i).name & "&nbsp;" Next // show the data for each record in the recordset While Not oRS.EOF For i = 0 to oRS.Fields.Count - 1 Response.Write oRS.Fields(i).value & "&nbsp;" Next Response.Write "<br />" oRS.Movenext() Wend End If

• PHP Check slave status without mysql_connect timeout issues

  - by Jonathon

  I have a web-app that has a master mysql db and four slave dbs. I want to handle all (or almost all) read-only (SELECT) queries from the slaves. Our load-balancer sends the user to one of the slave machines automatically, since they are also running Apache/PHP and serving webpages. I am using an include file to setup the connection to the databases, such as: //for master server (i.e. - UPDATE/INSERT/DELETE statements) $Host = "10.0.0.x"; $User = "xx"; $Password = "xx"; $Link = mysql_connect( $Host, $User, $Password ); if( !$Link ) ) { die( "Master database is currently unavailable. Please try again later." ); } //this connection can be used for READ-ONLY (i.e. - SELECT statements) on the localhost $Host_Local = "localhost"; $User_Local = "xx"; $Password_Local = "xx"; $Link_Local = mysql_connect( $Host_Local, $User_Local, $Password_Local ); //fail back to master if slave db is down if( !$Link_Local ) ) { $Link_Local = mysql_connect( $Host, $User, $Password ); } I then use $Link for all update queries and $Link_Local as the connection for SELECT statements. Everything works fine until the slave server database goes down. If the local db is down, the $Link_Local = mysql_connect() call takes at least 30 seconds before it gives up on trying to connect to the localhost and returns back to the script. This causes a huge backlog of page serves and basically shuts down the system (due to the extremely slow response time). Does anyone know of a better way to handle connections to slave servers via PHP? Or, is there some kind of timeout function that could be used to stop the mysql_connect call after 2-3 seconds? Thanks for the help. I searched the other mysql_connect threads, but didn't see any that addressed this issue.

• MD5CryptoServiceProvider ComputeHash Issues between VS 2003 and VS 2008

  - by owensoroke

  I have a database application that generates a MD5 hash and compares the hash value to a value in our DB (SQL 2K). The original application was written in Visual Studio 2003 and a deployed version has been working for years. Recently, some new machines on the .NET framework 3.5 have been having unrelated issues with our runtime. This has forced us to port our code path from Visual Studio 2003 to Visual Studio 2008. Since that time the hash produced by the code is different than the values in the database. The original call to the function posted in code is: RemoveInvalidPasswordCharactersFromHashedPassword(Text_Scrub(GenerateMD5Hash(strPSW))) I am looking for expert guidance as to whether or not the MD5 methods have changed since VS 2K3 (causing this point of failure), or where other possible problems may be originating from. I realize this may not be the best method to hash, but utimately any changes to the MD5 code would force us to change some 300 values in our DB table and would cost us a lot of time. In addition, I am trying to avoid having to redeploy all of the functioning versions of this application. I am more than happy to post other code including the RemoveInvalidPasswordCharactersFromHashedPassword function, or our Text_Scrub if it is necessary to recieve appropriate feedback. Thank you in advance for your input. Public Function GenerateMD5Hash(ByVal strInput As String) As String Dim md5Provider As MD5 ' generate bytes for the input string Dim inputData() As Byte = ASCIIEncoding.ASCII.GetBytes(strInput) ' compute MD5 hash md5Provider = New MD5CryptoServiceProvider Dim hashResult() As Byte = md5Provider.ComputeHash(inputData) Return ASCIIEncoding.ASCII.GetString(hashResult) End Function

• Bazaar offline + branches

  - by cheez

  I have a Bazaar repository on Host A with multiple branches. This is my main repository. Until now, I have been doing checkouts on my other machines and committing directly to the main repository. However, now I am consolidating all my work to my laptop and multiple VMs. I need to be working offline regularly. In particular, I need to create/delete/merge branches all while offline. I was thinking of continuing to have the master on Host A with a clone of the repository on the laptop with each vms doing checkouts of the clone. Then, when I go offline, I could do bzr unbind on the clone and bzr bind when I am back online. This failed as soon as I tried to bzr clone since bzr clone only clones a branch(!!!!) I need some serious help. If Hg would handle this better please let me know (I need Windows support.) However, at this moment I cannot switch from Bazaar as it is too close to some important deadlines. Thanks in advance!

• Xcode Code Sense horribly broken?

  - by Philippe Leybaert

  Ever since I started using Xcode, I've experienced extremely annoying problems using Xcode and Code Sense. The problem is that when Code Sense kicks in for code completion, sometimes the source code text below the line I'm working on goes "crazy". If I continue typing, the problem gets worse, and after a while the source code is completely screwed up (funny colors, missing lines and characters, ...). Strange enough, the source code itself is unaffected, because when I select another source file and then go back to the one I was working on, everything looks fine again. The problem can be seen in this screencast: http://www.screencast.com/t/OGY3NWE5 Interesting facts: This problem has occurred on 3 different machines, so it's not related to a corrupt installation. Sometimes it's fine for a while (up to one hour) after launching Xcode, but once it starts happening, it's getting worse and worse, until Xcode is restarted. Then it's fine again (for a while) I've searched the web for similar experiences, and I can't find anything. I would think that it is a known problem, since it occurs on 3 different Macs here (both running 10.5 and 10.6). Anyone having the same problems? Or a suggestion for fixing this?

The exact same project compiles perfectly fine on other machines, so it can't be the code itself.. I've spent countless errors researching, which led to desperate attempts of just changing random values in the solution file, including different Windows headers, etc. My last resort is getting to be just reinstalling the OS completely (assuming it's actually a problem with the Windows SDK being incorrect or something). Any suggestions at all would be a huge help. EDIT: I've added /showIncludes on the cpp giving issues, and I do see afxtempl.h being included. It's being included multiple times due to other headers including it, but it is there (and it is from the same directory every time): 1> Note: including file: C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\atlmfc\include\afxtempl.h

• Enterprise Platform in Python, Design Advice

  - by Jason Miesionczek

  I am starting the design of a somewhat large enterprise platform in Python, and was wondering if you guys can give me some advice as to how to organize the various components and which packages would help achieve the goals of scalability, maintainability, and reliability. The system is basically a service that collects data from various outside sources, with each outside source having its own separate application. These applications would poll a central database and get any requests that have been submitted to perform on the external source. There will be a main website and REST/SOAP API that should also have access to the central data service. My initial thought was to use Django for the web site, web service and data access layer (using its built-in ORM), and then the outside source applications can use the web service(s) to get the information they need to process the request and save the results. Using this method would allow me to have multiple instances of the service applications running on the same or different machines to balance out the load. Are there more elegant means of accomplishing this? i've heard of messaging systems such as MQ, would something like that be beneficial in this scenario? My other thought was to use a completely separate data service not based on Django, and use some kind of remoting or remote objects (in they exist in Python) to interact with the data model. The downside here would be with the website which would become much slower if it had to push all of its data requests through a second layer. I would love to hear what other developers have come up with to achieve these goals in the most flexible way possible.

• How-to diagnose and fix such "on-site" crash of dotnet application?

  - by Dmitriy Matveev

  Hello! I'm working on some application which has auto-update function. The implemented idea is simple as following: - There are some "starter" application which is installed to "Program Files/whatever/...". It's the application which is intended to be started by user. - Each time the "starter" application is executed it checks server for updates and downloads it to "%APPDATA%/some/...". And then it starts some application from that folder. Above approach is working on my development machine (running Vista) and on some other machines under XP, but under some different machine (running Windows 7) it isn't working. When "starter" executes the real application it crashes with some unknown problem (Signature = System.UnauthorizedAccess). When real application is executed manually from %APPDATA%/some/ folder then everything is working fine. I've tried to set same working directory in ProcessStartInfo, so "starter" will also execute real application in that folder, but this isn't helped me. How can I diagnose and/or fix that issue?

• Disabling Remote-Debugging Connection on Windows 2000

  - by Kim Leeper

  I have two machines one running Win 2000 and one running Win XP both with VSC++ 6. I created an application on the Win XP machine (local) and sucessfuly used the Win2000 machine (remote) as the target for debugging. The code was in a shared drive on the Win2000 machine. This setup worked well, just like in the movies! However, I now wish to use my Win2000 machine as a develpment machine again and I find I can not. When attempting to execute a natively compiled application on this machine, I get a dialog with the title of "Remote Execution Path And Filename" asking me for same. When dialog is cancelled as the program that is attemptng to execute is not remote, the program terminates without error. Extra info! On the WinXP machine, VSC++, under the Build menu-Debugger Remote Connection-Remote Connection Dialog-the "Connection:" list box has two entries 'Local' and 'Network', on the Win2000 machine the 'Local' entry is not present, only the entry for 'Network'. How do I get back my 'Local' entry on what used to be my target machine?

• Re-authentication required for registered-path links (to ASP.NET site) coming to IE from PowerPoint

  - by Daniel Halsey

  We're using URL routing based on Phil Haack's example, with config modifications based on MSDN Library article #CC668202, to provide "shareable" links for a ASP.NET forms site, and have run into a strange issue: For users attempting to open links from PowerPoint presentations, and who have IE set as their default browser, using one of these links forces (forms-based) re-authentication, even in the same browser instance with a live session. Info: We know the session is still alive. (Page returns information for the currently logged-in user; confirmed via debug watches) This doesn't happen with other browsers (FF, Chrome) or with other programs (Notepad++) as the URL source. We do not have a default path set, as this caused issues with root path handling at initial login. This primarily happens with PowerPoint, but will also happen in Word and OCS. On some machines, even after changing the default browser, Office apps will continue to use IE for these links, forcing this error. (A potential registry fix for this failed, but even if it had worked, we can't control default browser choice for our users.) We can't figure out if this is an Office oddity or is being caused by our decision to use app-level URL routing (rather than IIS rewriting). Has anyone else encountered this and found a solution?

• Using TXMLDocument to serialize form settings to XML and database.

  - by LukLed

  I have an interface: type IXMLSerializable = interface function SaveToXML : DOMString; function SaveToXMLDocument : IXMLDocument; procedure LoadFromXML(AXML : DOMString); end; It is used to serialize some settings of forms or frames to xml. Simple implementation: SaveToXMLDocument: function TSomething.SaveToXMLDocument: IXMLDocument; begin Result := TXMLDocument.Create(nil); with Result do begin Active := True; with AddChild(Self.Name) do begin AddChild(edSomeTextBox.Name).Attributes['Text'] := edSomeTextBox.Text; end; end; Result := XMLDoc; end; LoadFromXML: procedure TSomething.LoadFromXML(AXML: DOMString); var XMLDoc : IXMLDocument; I : Integer; begin XMLDoc := TXMLDocument.Create(nil); with XMLDoc do begin LoadFromXML(AXML); Active := True; with ChildNodes[0] do begin for I := 0 to ChildNodes.Count-1 do begin If ChildNodes[I].NodeName = 'edSomeTextBox' then edSomeTextBox.Text := ChildNodes[I].Attributes['Text']; end; end; end; end; SaveToXML: function TSomething.SaveToXML: DOMString; begin SaveToXMLDocument.SaveToXML(Result); end; DOMString result of SaveToXML is saved to database to blob field. I had some encoding issues with other implementations and this one works fine (right now). Do you see any dangers in this code? Can I have issues with different settings on various machines and systems?

• Anyone Experiencing Slow Builds With VS2010?

  - by MrKWatkins

  Hi, We've recently upgraded to the final release of VS2010 and are experiencing very slow build times compared to the same code under 2008. I was wondering if anyone else is experiencing the same so I can work out whether it's just our environment or not? A few details: Using VS2010 Ultimate on Windows 7 with fairly beefy machines, talking to TFS 2010. The solution has been upgraded from VS2008 but still builds against .NET 3.5 and ASP.NET MVC 1.0. It doesn't seem to be the compilation itself taking long but something else in the build process. This is because even projects that are up to date and don't need compiling are taking a few seconds or so to process. It's not due to an Visual Studio addin because a couple guys in the team haven't installed any. The first build after loading VS2010 is pretty quick, then they seem to slow down over time. For example on of the projects in my solution just took 00:00:00.08 to process after a restart. (The project was up to date and didn't need compiling) I then immediately hit rebuild and it jumps to 00:00:01.33. We're also experiencing the problem with another solution that uses .NET 4.0 that was building perfectly fine under VS2010 RC. There are no build events or anything like that I can blame, just straightforward assembly builds. The IDE is not very responsive during the slow builds. Anyone else has similar problems? Update: It looks like the resolving assembly references is taking a long time. Looking at the MSBuild diagnostic output or the example above the first build has 30ms for ResolveAssemblyReferences, the second build has 800ms. Subsequent builds seem to be taking longer copying stuff around, e.g. CopyFilesToOutputDirectory jumps from 1ms to 27ms.

• Maven build issue with Hibernate for Windows

  - by wishi_

  Hi! I'm getting build errors for for my Maven enabled project related to the Hibernate extension. - It's a very basic app, and I was able to solve this issue on my Linux box by manually installing some required artifacts: mvn install:install-file -DgroupId=javassist -DartifactId=javassist -Dversion=3.9.0 -Dpackaging=jar -Dfile=foo.jar That worked out (Hibernate as a set of required deps). But in case of Windows things are different. How do I add the dependencies manually to Maven on Windows? 1) org.hibernate:hibernate:jar:3.3.2 Try downloading the file manually from the project website. Then, install it using the command: mvn install:install-file -DgroupId=org.hibernate -DartifactId=hibernate -Dversion=3.3.2 -Dpackaging=jar -Dfile=/path/to/file 2) javassist:javassist:jar:3.9.0 Can I automate this cumbersome manual dependency installation for my coworkers on their Windows machines? Are there any helpful tools or GUI that can perform these tasks? The best way would be that Maven does it all automatically. I'm not too familiar with it jet. Thanks for answers.

• unbuffered I/O in Linux

  - by stuck

  I'm writing lots and lots of data that will not be read again for weeks - as my program runs the amount of free memory on the machine (displayed with 'free' or 'top') drops very quickly, the amount of memory my app uses does not increase - neither does the amount of memory used by other processes. This leads me to believe the memory is being consumed by the filesystems cache - since I do not intend to read this data for a long time I'm hoping to bypass the systems buffers, such that my data is written directly to disk. I dont have dreams of improving perf or being a super ninja, my hope is to give a hint to the filesystem that I'm not going to be coming back for this memory any time soon, so dont spend time optimizing for those cases. On Windows I've faced similar problems and fixed the problem using FILE_FLAG_NO_BUFFERING|FILE_FLAG_WRITE_THROUGH - the machines memory was not consumed by my app and the machine was more usable in general. I'm hoping to duplicate the improvements I've seen but on Linux. On Windows there is the restriction of writing in sector sized pieces, I'm happy with this restriction for the amount of gain I've measured. is there a similar way to do this in Linux?
