  • Generating new sources via Maven plugin after compile phase

    - by japher
    I have a Maven project within which I need execute two code generation steps. One generates some Java types, then the second depends on those Java types to generate some more code. Is there a way to have both of these steps happening during my build? At the moment my steps are: execute first code generation plugin (during generate-sources) add directory of generated types to build path execute second code generation plugin (during compile) However my problem is that anything generated by the second code generation plugin will not be compiled (because the compile phase has finished). If I attach the second code generation plugin to an earlier phase, it fails because it needs the classes from the first code generation plugin to be present on the classpath. I know I could split this into two modules with one dependent on the other, but I was wondering if this could be achieved in one pom. It seems like a need a way to invoke compile again after the normal compile phase is complete. Any ideas?

  • How can we plan projects realistically while accounting for support issues?

    - by Thomas Clayson
    We're having a problem at work: we're trying to schedule work so that we can assess time scales and get deadline dates. The problem is that it's difficult to plan for a project without knowing everything that's going to happen. For instance, right now we've planned all our projects through the start of December, however in that time we will have various in house and external meetings, teleconferences and extra work. It's all well and good to say that a project will take three weeks, but if there is a week's worth of interruption in that time then the date of completion will be pushed back a week. The problem is 3 fold: When we schedule projects the time scales are taken literally. If we estimate three weeks, the deadline is set for three week's time, the client is told, and there is no room for extension. Interim work and such means that we lose productive time working on the project. Sometimes clients don't have the time that we need to take to do the work, so they'll sometimes come to us and say they need a project done by the end of the month even when we think that the work will take two months - not to mention we already have work to be doing. We have a Gantt chart which we are trying to fill in with all the projects we have and we fill in timesheets, but they're not compared to the Gantt chart at all. This makes it difficult to say "Well, we scheduled 3 weeks for this project, but we've lost a week here so the deadline has to move back a week." It's also not professional to keep missing deadlines we've communicated to the client. How do other people deal with this type of situation? How do you manage the planning of projects? How much "extra" time do you schedule into a project to account for non-project work that occurs during a project? How do you deal with support issues and bugs and stuff? Things you can't account for during planning? UPDATE Lots of good answers thank you.

  • Render rivers in a grid.

    - by Gabriel A. Zorrilla
    I have created a random height map and now i want to create rivers. I've made an algorithm based on a* to make rivers flow from peaks to sea and now i'm in the quest of figuring out an elegant algorithm to render them. It's a 2D, square, mapgrid. The cells which the river pases has a simple integer value with this form :rivernumber && pointOrder. Ie: 10, 11, 12, 13, 14, 15, 16...1+N for the first river, 20,21,22,23...2+N for the second, etc. This is created in the map grid generation time and it's executed just once, when the world is generated. I wanted to treat each river as a vector, but there is a problem, if the same river has branches (because i put some noise to generate branches), i can not just connect the points in order. The second alternative is to generate a complex algorithm where analizes each point, checks if the next is not a branch, if so trigger another algorithm that take care of the branch then returns to the main river, etc. Very complex and inelegant. Perhaps there is a solution in the world generation algorithm or in the river rendering algorithm that is commonly used in these cases and i'm not aware of. Any tips? Thanks!!

  • generating maps

    - by gardian06
    This is a conglomeration question when answering please specify which part you are addressing. I am looking at creating a maze type game that utilizes elevation. I have a few features I would like to have, but am unsure as to some of the implementation. I have done work doing fileIO maze generation (using a key to read the file, and then generate the level based on that file), but I am unsure how to think about this with elevation in the mix. I think height maps might be a good approach, but don't know how to represent them effectively. for a height map which is more beneficial XML(containing h[u,v] data and key definition), CSV (item1 is key reference, item2 is elevation), or another approach that I have not thought of yet? When it comes to placing the elevation values themselves what kind of deltah values are appropriate to have it noticeable at about a 60degree angle while not really effecting gravity driven physics (assuming some effect while moving up/down hill)? I am thinking of maybe going to procedural generation at some point, but am wondering if it is practical to have a procedurally generated grid (wall squares possibly same dimensions as the open space squares), or if designing to a thin wall open spaces is better? this decision will effect the amount of work need on the graphics end for uniform vs. irregular walls. EDIT: game will be a elevation maze shooter. levels/maps will be mazes with elevation the player has to negotiate. elevations will have effects on "combat" vision, and movement

  • WCF code generation for large/complex schema (HR-XML/OAGIS) - is there an alternative?

    - by Sasha Borodin
    Hello, and thank you for reading. I am implementing a WCF Service based on a predefined specification (HR-XML 3.0). As such, I am starting with the schema, and working my way back to code. There are a number of large Schema documents (which import yet more Schema documents) related to my implementation, provided by this specification. I am able to generate code using xsd.exe, by supplying the "main" and "supporting" xsd files as arguments. But there are several issues, and I am wondering if this is the right approach. there are litterally hundreds of classes - the code file is half a meg in size duplicate classes (ex. Type, Type1 - which both represent the same type) there are classes declared as inheriting from a base class, but that base class is not generated/defined I understand that there are limitations to the types of Schema supported by svcutil.exe/xsd.exe when targeting the DataContractSerializer and even XmlSerializer. My question is two-fold: Are code generation "issues" fairly common when dealing with larger, modular xsd files? Has anyone had success with generating data contracts from OAGIS or HR-XML schema? Given the above issues, are there better approaches to this task, avoiding generating code and working with concrete objects? Does it make better sence to read and compose a SOAP message directly, while still taking advantage of the rest of the WCF framework? I understand that I am loosing the convenience of working with .NET objects, and the framekwork-provided (de)serialization; given these losses, would it still be advantageous to base my Service on WCF? Is there some "middle ground" between working with .NET types and pure XML? Thank you very much! -Sasha Borodin DFWHC.org

  • Intelligent search and generation of Java code, preferrably using Python?

    - by Ipsquiggle
    Basically, I do lots of one-off code generation, large-scale refactorings, etc. etc. in Java. My tool language of choice is Python, but I'll take whatever solutions you can offer. Here is a simplified illustration of what I would like, in a pseudocode Generating an implementation for an interface search within my project: for each Interface as iName: write class(name=iName+"Impl", implements=iName) search within the body of iName: for each Method as mName: write method(name=mName, body="// TODO implement this...") Basically, the tool I'm searching for would allow me to: parse files according to their Java structure ("search for interfaces") search for words contextualized by language elements and types ("variables of type SomeClass", "doStuff() method calls on SomeClass instances") to run searches with structural context ("within the body of the current result") easily replace or generate code (with helpers to generate, as above, or functions for replacing, "rename the interface to Foo", "insert the line Blah.Blah()", etc.) The point is, I don't want to spend a lot of time writing these things, as they are usually throwaway. But sometimes I need something just a little smarter than what grep offers. It wouldn't be too hard to write up a simplistic version of this, but if I'm going to use something like this at all, I'd expect it to be robust. Any suggestions of a tool/library that will help me accomplish this?

  • ScheduledThreadPoolExecutor executing a wrong time because of CPU time discrepancy

    - by richs
    I'm scheduling a task using a ScheduledThreadPoolExecutor object. I use the following method: public ScheduledFuture<?> schedule(Runnable command, long delay,TimeUnit unit) and set the delay to 30 seconds (delay = 30,000 and unit=TimeUnit.MILLISECONDS). Sometimes my task occurs immediately and other times it takes 70 seconds. I believe the ScheduledThreadPoolExecutor uses CPU specific clocks. When i run tests comparing System.currentTimeMillis(), System.nanoTime() [which is CPU specific] i see the following schedule: 1272637682651ms, 7858346157228410ns execute: 1272637682667ms, 7858386270968425ns difference is 16ms but 4011374001ns (or 40,113ms) so it looks like there is discrepancy between two CPU clocks of 40 seconds How do i resolve this issue in java code? Unfortunately this is a clients machine and i can't modify their system.

  • How to force a clock update using ntp?

    - by ysap
    I am running Ubuntu on an ARM based embedded system that lacks a battery backed RTC. The wake-up time is somewhere during 1970. Thus, I use the NTP service to update the time to the current time. I added the following line to /etc/rc.local file: sudo ntpdate -s time.nist.gov However, after startup, it still takes a couple of minutes until the time is updated, during which period I cannot work effectively with tar and make. How can I force a clock update at any given time? UPDATE 1: The following (thanks to Eric and Stephan) works fine from command line, but fails to update the clock when put in /etc/rc.local: $ date ; sudo service ntp stop ; sudo ntpdate -s time.nist.gov ; sudo service ntp start ; date Thu Jan 1 00:00:58 UTC 1970 * Stopping NTP server ntpd [ OK ] * Starting NTP server [ OK ] Thu Feb 14 18:52:21 UTC 2013 What am I doing wrong? UPDATE 2: I tried following the few suggestions that came in response to the 1st update, but nothing seems to actually do the job as required. Here's what I tried: Replace the server to us.pool.ntp.org Use explicit paths to the programs Remove the ntp service altogether and leave just sudo ntpdate ... in rc.local Remove the sudo from the above command in rc.local Using the above, the machine still starts at 1970. However, when doing this from command line once logged in (via ssh), the clock gets updated as soon as I invoke ntpdate. Last thing I did was to remove that from rc.local and place a call to ntpdate in my .bashrc file. This does update the clock as expected, and I get the true current time once the command prompt is available. However, this means that if the machine is turned on and no user is logged in, then the time never gets updates. I can, of course, reinstall the ntp service so at least the clock is updated within a few minutes from startup, but then we're back at square 1. So, is there a reason why placing the ntpdate command in rc.local does not perform the required task, while doing so in .bashrc works fine?

  • Visitor pattern and compiler code generation, how to get children attributes?

    - by LeleDumbo
    I'd like to modify my compiler's code generator to use visitor pattern since the current approach must use multiple conditional statement to check the real type of a child before generating the corresponding code. However, I have problems to get children attributes after they're visited. For instance, in binary expression I use this: LHSCode := GenerateExpressionCode(LHSNode); RHSCode := GenerateExpressionCode(RHSNode); CreateBinaryExpression(Self,LHS,RHS); In visitor pattern the visit method is usually void, so I can't get the expression code from LHS and RHS. Keeping shared global variables isn't an option since expression code generation is recursive thus could erase previous values kept in the variables. I'll just show the binary expression as this is the most complicated part (for now): function TLLVMCodeGenerator.GenerateExpressionCode( Expr: TASTExpression): TLLVMValue; var BinExpr: TASTBinaryExpression; UnExpr: TASTUnaryExpression; LHSCode, RHSCode, ExprCode: TLLVMValue; VarExpr: TASTVariableExpression; begin if Expr is TASTBinaryExpression then begin BinExpr := Expr as TASTBinaryExpression; LHSCode := GenerateExpressionCode(BinExpr.LHS); RHSCode := GenerateExpressionCode(BinExpr.RHS); case BinExpr.Op of '<': Result := FBuilder.CreateICmp(ccSLT, LHSCode, RHSCode); '<=': Result := FBuilder.CreateICmp(ccSLE, LHSCode, RHSCode); '>': Result := FBuilder.CreateICmp(ccSGT, LHSCode, RHSCode); '>=': Result := FBuilder.CreateICmp(ccSGE, LHSCode, RHSCode); '==': Result := FBuilder.CreateICmp(ccEQ, LHSCode, RHSCode); '<>': Result := FBuilder.CreateICmp(ccNE, LHSCode, RHSCode); '/\': Result := FBuilder.CreateAnd(LHSCode, RHSCode); '\/': Result := FBuilder.CreateOr(LHSCode, RHSCode); '+': Result := FBuilder.CreateAdd(LHSCode, RHSCode); '-': Result := FBuilder.CreateSub(LHSCode, RHSCode); '*': Result := FBuilder.CreateMul(LHSCode, RHSCode); '/': Result := FBuilder.CreateSDiv(LHSCode, RHSCode); end; end else if Expr is TASTPrimaryExpression then if Expr is TASTBooleanConstant then with Expr as TASTBooleanConstant do Result := FBuilder.CreateConstant(Ord(Value), ltI1) else if Expr is TASTIntegerConstant then with Expr as TASTIntegerConstant do Result := FBuilder.CreateConstant(Value, ltI32) else if Expr is TASTUnaryExpression then begin UnExpr := Expr as TASTUnaryExpression; ExprCode := GenerateExpressionCode(UnExpr.Expr); case UnExpr.Op of '~': Result := FBuilder.CreateXor( FBuilder.CreateConstant(1, ltI1), ExprCode); '-': Result := FBuilder.CreateSub( FBuilder.CreateConstant(0, ltI32), ExprCode); end; end else if Expr is TASTVariableExpression then begin VarExpr := Expr as TASTVariableExpression; with VarExpr.VarDecl do Result := FBuilder.CreateVar(Ident, BaseTypeLLVMTypeMap[BaseType]); end; end; Hope you understand it :)

  • Best way to restore individual folders via Time Machine after clean Lion install?

    - by A4J
    I'm doing a clean erase and install of Lion, and am looking for the best way to restore individual folders into my home directory via Time Machine. I've done a dummy run, clean Lion install, then 'browse other disks' in Time Machine, navigate to my home folder and 'restore' what I need, such as pictures/music and folders inside the .library folder (such as Mail and Keychains). However this method seems to give you odd permissions, like this: http://i43.tinypic.com/15y82v4.png Hence I wondered if anyone knows what the best method is to restore files and folders after a clean install. N.b I do not want to use the migration assistant, or 'restore OS from Time Machine' - as I specifically want to do a clean install, and just copy over what I need (some folders will be moved onto a separate disk to the OS, and some will remain on the same disk). Thanks in advance.

  • Is it reasonable to use my Time Machine backup to migrate to a new primary hard drive?

    - by Michael Haren
    I'm planning to upgrade my MacBook's harddrive. I already use Time Machine to back up the system to an external drive. Is it reasonable to use Time Machine to restore my system to the new laptop drive, once I install it? I mean, a restore like this really ought to be fine, right? That's the point of it, after all! I know imaging the drive would be more appropriate but this plan seems a whole lot easier (albeit probably slower), with practically no risk since my original drive won't be involved. A second question would then be, are there any considerations to be made when doing a Time Machine restore?

  • Is an Ethernet point to point connection without a switch real time capable?

    - by funksoulbrother
    In automation and control, it is commonly stated that ethernet can't be used as a bus because it is not real time capable due to packet collisions. If important control packets collide, they often can't keep the hard real time conditions needed for control. But what if I have a single point to point connection with Ethernet, no switch in between? To be more precise, I have an FPGA board with a giga-Ethernet port that is connected directly to my control PC. I think the benefits of giga Ethernet over CAN or USB for a p2p connection are huge, especially for high sampling rates and lots of data generation on the FPGA board. Am I correct that with a point to point connection there can't be any packet collisions and therefore a real time environment is given even with ethernet? Thanks in advance! ~fsb

  • How to reuse backup on Time Machine on Snow Leopard after a logic board change, after choosing wrong

    - by kmiffy
    After my logic board was replaced, I connected my laptop back to my network, and Time Machine gave me a popup, as shown on this thread: http://superuser.com/questions/78068/recycle-time-machine-for-new-machine/78264#78264 I misread the question and clicked on "Create New Backup" when I should have clicked on "Reuse Backup" to connect to my old backup file. How can I trigger that popup again? Turning Time Machine on and off does not work, and the instructions on forums to fix via terminal doesn't work because snow leopard is missing the fsaclctl command (and I'm also not familiar with terminal commands.) Thanks.

  • What is normal SCSI error handling process (scsi_eh_3) CPU time usage?

    - by Kris Jordan
    Last week I got setup with a new dedicated server that is running 4x SCSI drives in RAID 10 on CentOS. The machine is pretty lightly loaded at the moment and has been running for 8 days. The process 'scsi_eh_3' has a CPU time of 13:09.67 in top. This is 3x the next closest CPU time of 4:03.93 for mysqld. Is it normal for the scsi error handling process to use this much CPU time? (Seems like it goes to 0.3% usage ever 5 seconds.) Could this be an indicator that one or more of the drives is having issues?

  • Is there any software or hardware which lets you stop, slow down, speed up or even reverse time?

    - by tjrobinson
    Obviously I'm talking about time in terms of the PC clock rather than real time. We were testing an application we've developed at work by setting the clock forward and back to simulate different scenarios and I started thinking how useful it would be if you could adjust the rate(?) of the system clock with finer control. So you could make a minute pass in a second or a day pass in 30 seconds and watch how the program you're developing copes with changes in date and time. I'd be interested to hear if anyone knows of any software or hardware which can let you do some or all of the above.

  • Is it safe to change the time on hosting VM server?

    - by hydroparadise
    So, I noticed there's about a 10 minute drift on my VM hosting server from what time it's supposed to be. In traditional environments, I would just restart the system (and change the BIOS time if necassary). The hosting server is Ubuntu 12.04. Undertsanding that some process could be time sensitive (NTP?), I was wondering how this might affect the relation between the host and hosted system (currently hosting 4: 3 Ubuntu 12.04 servers with one being a web server, and 1 Windows Server 2008 file server). I am using Virtual Box 4 with it's headless option. Ultimately, I am trying to avoid from shutting down the host (which ultimately mean shutthing down the other hosted systems). Is this safe?

  • Monitoring the wall time of a process on windows?

    - by Sean Madden
    Windows Task Manager has the ability to show the current CPU time of any given running process on windows, is there any way (not necessarily through Task Manager) to get the current wall time of a process? An example, let's say I have a script that reliably runs for about 45 minutes. Without adding a progress bar to the script, is there any way to figure out for how long it has been running? The math behind this seems pretty straight forward; WallTime = CurrentWallTime - WallTimeProcessStarted. Likewise, since the math is so simple, is there anyway to get the time that a process was started at?

  • Is there a time machine equivalent for windows that can back up network files?

    - by Jim Thio
    This question is similar to Does an equivalent of Time Machine exist for Windows?, with one difference: The files I want to back up are on a network drive. The computer on that network drive is running Windows XP. I want to back up data on Windows 7. How would I do so? I'd like something similar to Mac OS X' time machine. So copy of data every hour, day, week. Then thinning out, data gets deleted automatically as time goes by. For example, the data for last day is kept as hourly snapshots. For last week, as daily snapshots every day. And for last month as weekly snapshots. How can I achieve this?

  • Cloud storage services offering one-time download links? [closed]

    - by TARehman
    Is anyone aware of consumer-targeted cloud storage services that allow users to generate a one-time download link for hosted files? Case in point: I have an encrypted container with some documents I need to send to a vendor. I would prefer to give them a one-time download link, so that I know when they have accessed the file, and then inform them of the passphrase by phone. I have heard that MediaFire offers 1-time links, but that they are buried in tons of advertising. At the moment, I'm not sure that I consider MediaFire fully legitimate; I'm more interested in solutions with Google Drive, Box.net, DropBox, etc.
