  • Using Mercurial repository inside a Git one: Feasible? Sane?

    - by Portablejim
    I am thinking on creating a Mercurial repository under a Git repository. e.g. ..../git-repository/directory/hg-repo/ The 2 repositories Is it possible to manage (keeping your sanity)? How similiar is it to this? I am a computer science student at University. I manage my work in Git, mainly as a distribution mechanism (after realizing that rsync fails when you have changes in more than one place) between my desktop and usb drive. I try use of Git as a VCS as I do work. I have finished a semester where I did a small group project to prepare for a larger group project next year. We had to use Subversion, and experienced the joys of a centralised VCS (including downtime). I tried to keep the subversion repository separate to my Git repository for the subject**, however it was annoying that it was seperate (not in the place where I store assignments). I therefore moved to using an Subversion repository inside my Git repository. As I think ahead (maybe I am thinking too far ahead) I realise that I will have to try and convince people to use a DVCS and Mercurial will probably be the one that is preferred (Windows and Mac GUI support, closer to Subversion). Having done some research into the whole Git vs Mercurial debate (however not used Mercurial at all) I still prefer Git. Can I have a Mercurial repository inside a Git one without going mad (or it ruining something)? Or is it something that I should not consider at all? (Or is it a bad question that should be deleted?) ** I think outside of Australia it is called a course

  • How to make it so units don't stack up in one location?

    - by Daggio
    So I'm making a game in AS3, it's a strategy DotA-like game (for flash game equivalent, there's UDE) so far so good, I have the A* pathfinding algorithm all sorted out and the minion units move to the desired location as I want them to be. The problem a rise when a unit stops in a node that has already occupied by another friendly unit. Both (or more than two) of them stacks up in one location, it looks like they're one unit. I want to add collision detection so when they collide they don't stack up together. But now they stop when they collide on they way to a node. This isn't good because they won't move at all midway (they won't respond to enemy attacks like that). I've added a deltatime so they only stopped for 2 seconds before they move again to their designated designation. This moves them again but they flicker. Not how I want it. So, like the title said. How to make more than one units don't stack up in a node? And if possible, how to make them not flicker while moving (it's good if they can tell other friendly units on the way and avoid them accordingly)?

  • Herding Cats - That's My Job....

    - by user709270
    Written by Mike Schmitz - Sr. Director, Program Management Oracle JD Edwards  I remember seeing a super bowl commercial several years ago showing some well dressed people on the African savanna herding cats. I remember turning to the people I was watching the game with and telling them, “You just watched my job description”. Releasing software is a multi-facetted undertaking. In addition to making sure the code changes are complete, you also need to make sure the other key parts of a release are ready. For example when you have a question about the software, will the person on the other end of the phone be ready to answer your question? If you need training on that cool new piece of functionality, will there be an online training course ready for you to review? If you want to read about how the software is supposed to function, is there a user manual available? Putting all the release pieces together so they are available at the same time is what the JD Edwards Program Management team does. It is my team’s job to work with all the different functional teams so when a release is made generally available you have all the things you need to be successful. The JD Edwards Program Management team uses an internal planning tool called the Release Process Model (RPM) to ensure all deliverables are accounted for in a release. The RPM makes sure all the release deliverables are ready at the correct time and in the correct format. The RPM really helps all the functional teams in JD Edwards know what release deliverables they are accountable for and when they are to be delivered. It is my team’s job to make sure everyone understands what they need to do and when they need to deliver. We then make sure they are all on track to deliver on-time and in the right format. It is just that some days this feels like herding cats.

  • Is it possible to keep only one Database for both web and desktop applications?

    - by B4NZ41
    I'm experiencing a trouble with my business model, let me explain better. I'm developing a software for 1 year and few months, it's for the food industry, more exactly a software to: Delivery, Take Way, Table Reservation, POS, Accounts Payable and Receivable, Prints(receipt), Kitchen Monitors Orders, Customers Orders Control and Fiscal Area. Well, I had separated the software mainly in two areas, one is web area and the other is desktop area (Used by Admins only) and local installed. 1 - Web Area (Basically do the follow:) Show Catalog with the products Customers Make Orders Customers Pay for the Orders etc ... as mentioned above 2 - Desktop Area Manage Orders Manage Customers Manage Suppliers Manage Accounts Payable and Receivable etc ... as mentioned above The web area is hosted in an online web server (scripts and database are online). The Desktop area is hosted locally in a Linux machine with a local database and local scripts files. My question is: Is it possible to keep only one Database for both applications? If YES, please what is the best approach? Follow my technical specification environment Database: Actually I have two databases working and I would love to keep only one. Operating System: Linux (Kernel 2.6.X and above) or Windows (XP and above) For the Web Area Apache, PHP, Python, Java Script, Shell Script and MySQL. For the Desktop Area: PHP-GTK2, Apache, PHP, MySQL and Shell Script.

  • iDevice for Dummies: Can a device be assigned multiple provisions (Personal/Enterprise)?

    - by Alex
    Hi guys, Is it possible to assign multiple provisions to an iDevice? To be honest, I'm not sure if I'm using the correct terminology, but basically, I'm developing an iPad app for a company and I've only been testing it in the simulator because I don't have a registration to the developer program and they haven't setup their enterprise registration yet either. And I'm sure you all know how limited the simulator is... I don't really care about the $99 it costs to join, but what I'm worried about is having my iDevices locked permanently to my personal registration and unable to switch back and forth to the enterprise registration. I'd appreciate it if someone can explain to me how the registrations work. And keep in mind, I'm a dummy. :) Thanks in advance!

  • What Is The Proper Location For One-Offs In VCS Repos?

    - by Joe Clark
    I have recently started using Mercurial as our VCS. Over the years, I have used RCS, CVS, and - for the last 5 years - SVN. Back 13 years ago, when I primarily used CVS and RCS, large projects went into CVS and one-offs were edited in place on the specific server and stored in RCS. This worked well as the one-offs were usually specific to the server and the servers were backed up nightly. Jump forward a decade and a lot of the one-off scripts became less centralized - they might be needed on any server at some random time. This was also OK, because now I was a begrudging SVN user. Everything (except for docs) got dumped into one repo. Jump to 2010. Now I am using Mercurial and am putting large projects in their own repo again. But what to do with the one-offs? The options as I see them: A repo for each script. It seems a bit cluttered to create a repo for every one page script that might get ran once a year. RCS Not an option. There are many possible servers that might need a specific script. Continuing to use SVN just for one-offs. No. There no advantage I see over the next option. Create a repo in Mercurial named "one-offs". This seems the most workable. The last option seems the best to me - however; is there a best practice regarding this? You also might be wondering if these scripts are truly one-offs if they will be reused. Some of them may be reused 6 months or a year from now - some, never. However, nearly all of them involve several man-hours of work due to either complex logic or extensive error checking. Simply discarding them is not efficient.

  • on Red Hat Enterprise and CentOS, what is creating /var/run/reboot-required?

    - by EdwardTeach
    On CentOS 5.8+ and Red Hat Enterprise 6+, when installing/updating packages, I notice a flag file /var/run/reboot-required is created when appropriate. On Ubuntu (and Debian too, I'm guessing), if package "update-notifier-common" is installed, a package postinst script triggers creation of this flag file. On RHEL/CentOS I can't figure out how this is happening. For instance, on RHEL and CentOS I recently installed several updates and /var/run/reboot-required was created. One of them was an "openssl" package upgrade. I assume this was what created the flag file, since on Ubuntu it also works this way. However I looked at all "rpm -q --scripts" for each updated package, and didn't see anything that was likely to have created that flag file. Mostly I saw "postinstall program: /sbin/ldconfig". So my questions are: What creates this flag file on RHEL/CentOS? Does it require a special package to be installed, analogous to the "update-notifier-common" package on Ubuntu?

  • How can I auto-connect to a WPA2 Enterprise network?

    - by Demetri
    I would like my computer to automatically connect to a WPA2-Enterprise network as soon as it boots whenever the network is available, without any action needed by me. The computer already offers to connect, and even remembers the password, but I must still hit 'Enter' to connect. Also, connection does not occur if my login is at the terminal. I would like to automatically connect every time I login, no matter how I do so, unless a more preferred network is available. What is the best way to do this? I am running Fedora 19. A shell script that can be invoked at the terminal would be preferred. Connecting even if the Gnome-desktop has not launched is a must.

  • Is there a network "tee"-alike with one leg returning to /dev/null ?

    - by Steff Davies
    I've just built a new PostgreSQL server for my employers, which is happily replicating using WALs. I'm now left with the problem of verifying its performance. One nice way which came up in conversation is to break replication with the slave caught up and then direct all production traffic to both servers, discarding the responses from the new server and returning those from the current one to the clients. Once we're sure performance is OK, we re-sync the slave and can fail over with confidence. Bliss. This would require a TCP proxy capable of opening two outgoing connections for each incoming one, and discarding the data returned from one of them, which is a tricky thing to google for, it seems. Do the assembled brains know of such a thing, before I dive into libevent and write one?

  • Is it possible create a 4TB bootable partition in the x86 edition of Windows Server 2003 Enterprise?

    - by Giffyguy
    I'd like to find out if there is any way to accomplish this, since it would benifit my storage server greatly. I am using a Promise FastTrak 8660 and five Seagate ST31000340NS 1TB drives in a RAID 5 array. I figure that if the x86 ENTERPRISE edition of Server 2003 can handle 64GB of RAM, it should have no problem supporting larger HDD volumes as well. I've read (somewhere...) that the Windows Server operating systems are not limited to the standard 2TB like Windows XP and 2000 are. I'm hoping it's something that just needs to be turned on, similar to the way PAE works for the 4GB RAM limit in x86 servers.

  • How to make the jump from consumer support to enterprise support?

    - by Zac Cramer
    I am currently a high level consumer break/fix technician responsible for about 300-400 repairs a month. I am good at my job, but bored, and I want to move into the enterprise side of my company, dealing with Server 2008 R2 and exchange and switches and routers that cost more than I make in a month. How do I make this transition? Whats the best thing to learn first? Is there a standard trajectory for making this leap from consumer to business? I am full time employed, so going back to school is not a great option, but I have no life, so spending my nights and weekends reading and practicing is totally within my realm. I am basically overwhelmed by the number of things to learn, and looking for any advice you may have on the best way to proceed. PS - I apologize if this is a not quite the right forum for this, I know its not a technical question exactly, but I also know the sorts of people I want to answer this question are reading this website.

  • How do I install automake and autoconf on RedHat Enterprise 5?

    - by Kevin Sedgley
    I am attempting to install "uploadprogress" for a PHP application, and have failed on dependencies. Firstly, on phpize, then php-devel, then on autoconf and automake. I have tried yum, and various repositories, with no luck. I think it's to do with the ultra-tight but annoying set up they have on Rackspace Cloud servers. Does anyone know where I can find a repository that I can tell yum to look at that will contain php-devel, autoconf, automake, etc? Thanks ever so much.

  • One vs. many domain user accounts in a server farm

    - by mjustin
    We are in a migration process of a group of related computers (Intranet servers, SQL, application servers of one application) to a new domain. In the past we used one domain user account for every computer (web1, web2, appserver1, appserver2, sql1, sqlbackup ...) to access central Windows resources like network shares. Every computer also has a local user account with the same name. I am not sure if this is necessary, or if it would be easier to configure and maintain to use one domain user account. Are there key advantages / disadvantages of having one single user account vs. dedicated accounts per computer for this group of background servers? If I am not wrong, one advantage besides easier administration of the user account could be that moving installed applications and services around between the computers does not require a check of the access rights anymore. (Except where IP addresses or ports are used)

  • How do I install yum on Redhat Enterprise 4?

    - by Bob Cross
    For historical reasons, one of the machines that I manage has a Redhat Enterprise 4 boot disk (among others). Every now and then, we have to boot into RHEL4 to bring up some of the legacy software that we support and connect to. Since it's a fringe system, the Redhat support has long since lapsed and I can't convince myself that it would be worth paying just to get RPMs that I can go and get for myself. That said, the default RHEL tools are heavily biased against letting you do exactly that. I would like to install yum and use that as my package discovery and installation. So, is there an installation guide to integrating yum with an older RHEL 4 system?

  • How to merge several detached signatures from different people into one?

    - by Petr Pudlák
    A group of people wants to publish a file and they all want to digitally sign the file as different recipients of the file will have different chains of trust. For simplicity, it's desired that there is only one detached signature file with all the signatures, so that the recipients don't need to check them one by one: foo.tar.gz foo.tar.gz.sig However, for security reasons, every person needs to perform the signing on their computer, it's not possible to create the combined signature by having multiple private keys on one computer and performing the operation with one command. Is it possible with GPG to somehow merge detached signatures of a file from multiple participants?

  • Does downloading the same torrent from more than one server increase the sources / seeds?

    - by Petruza
    Does downloading the same torrent from more than one server increase the sources / seeds? edit: What I meant with servers is those like mininova, isohunt and the like. Now I know those aren't the trackers, what I want to know is if when more than one of those indexing sites are linked for the same torrent, if they likely contain different lists of trackers, so getting the torrent from both sites will increase the trackers, hence the seeds, or if it's just in case one of the sites goes down. I guess I can test this getting one torrent from one site with a torrent client and the same torrent, from another site with another client and comparing the list of trackers and the amount of seeders and leechers.

  • How can I put all twill commands together into one piece of code in a .py file?

    - by brilliant
    Hello everybody! I have just started exploring TWILL. Twill is an amazing scripting language for Web browsing and it does all I want!!! So far I've been using twill from a Python shell (IDLE (Python GUI) to be precise) and I do things in the way of executing commands one by one (I mean, I type one command, run it, then type the next command): But I don't know how to put all these commands together in one .py file, so that they would all be executed one by one automatically. It seems that there is such possibility in twill. This example from the twill documentation page (you can see it HERE) shows us one piece of code consisting of several commands: So, my question is: How can I put all commands together in twill?

  • All articles with infinite scroll, or one per page for usability and SEO?

    - by Rana Prathap
    Imagine a hypothetical website with all user generated content of single page articles. Here are some ways to structuring such a website: Putting up more than one article in one page and creating an infinite scroll or a pager. The fact that the articles may not be on the same topic makes this a less search engine friendly way. Giving a unique page to each article and putting up a list of links/titles in the front page with or without a teaser and a thumbnail. This might make the home page look unprofessional. Keeping the front page clean, without direct links to internal pages. Which method would be a search engine friendly and user friendly way to do this?

  • Is sticking to one language on a particular project a good practice?

    - by Ans
    I'm developing a pipeline for processing text that will go into production. The question I keep asking myself is: should I stick to one language for the project when I'm looking for a tool to do a particular task (e.g. NLTK, PDFMiner, CLD, CRFsuite, etc.)? Or is it OK to mix and match languages on the project? So I pick the best tool regardless of what language it's written in (e.g. OpenNLP, ParsCit, poppler, CFR++, etc.) and warp (wrap) my code around it? Note, I am not asking about should a developer stick to just one language for their career.

  • Could not load file or assembly 'AjaxControlToolkit' or one of its dependencies. Access is denied.

    I wanted to post a solution to an issue that comes up every time I have to setup a new developer in our organization:      Could not load file or assembly 'AjaxControlToolkit' or one of its dependencies. Access is denied.  My solution is to grant Full Control to the "Everyone" group to the folder C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files  I know there are other solutions to this problem, but this one seems the simplest for me.  M...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • "sudo cd ..." one-liner?

    - by j-g-faustus
    Occasionally I want to cd into a directory where my user does not have permission, so I resort to sudo. The obvious command sudo cd somedir doesn't work: $ sudo mkdir test $ sudo chmod go-rxw test $ ls -l drwx------ 2 root root [...snip...] test $ cd test -bash: cd: test: Permission denied $ sudo cd test sudo: cd: command not found Using sudo su works: $ sudo su # cd test Is it possible to make this into a one-liner? (Not a big deal, just idle curiosity :) The variations I tried didn't work: $ sudo "cd test" sudo: cd: command not found $ sudo -i cd test -bash: line 0: cd: test: No such file or directory $ sudo -s cd test The last one doesn't give an error, but it cd's within a new shell that exits by the end of the line, so it doesn't actually take me anywhere. Can someone enlighten me as to why this happens? Why is sudo cd not found, when for example sudo ls ... works fine?

  • Simple vs Complex (but performance efficient) solution - which one to choose and when?

    - by ManojGumber
    I have been programming for a couple of years and have often found myself at a dilemma. There are two solutions - one is simple one i.e. simple approach, easier to understand and maintain. It involves some redundancy, some extra work (extra IO, extra processing) and therefore is not the most optimal solution. but other uses a complex approach,difficult to implement, often involving interaction between lot of modules and is a performance efficient solution. Which solution should I strive for when I do not have hard performance SLA to meet and even the simple solution can meet the performance SLA? I have felt disdain among my fellow developers for simple solution. Is it good practice to come up with most optimal complex solution if your performance SLA can be met by a simple solution?
