  • Splitting build cross the network?

    - by Dandikas
    Is there a known solution for splitting build process cross the network machines? Use case: We are an average software development company. We own around 50 development workstations (Quad Core 2.66Ghz, 4 GB ram, 200 GB raid). No need to tell that at any single moment not every machine is loaded to the max. There are 5 to 15 projects running simultaneously at any single moment. Obviously all of them are continuously build on server, than deployed to proper environment. Single project build is taking from 3 to 15 minutes. The problem: Whenever we build 5 projects in a row the last project is going to be ready after around 25 - 50 minutes. Building in parallel does not solve the problem (build is only a part of the game, than you need to deploy, run tests etc.) YES the correct solution is to add another build server, but "That involves buying new Expensive hardware, and we already spent a lot!". Yea, right(damn them)! Anyway. What about splitting build among developers workstation? Lets say whenever we need to build project "A" we check 5 workstations and start build on all that are not overloaded. The build can be canceled by a developer if he really needs all the power of his machine as long as there is at least 1 machine that is still building. After build is finished deployment can be performed to a proper environment (hosted on some server, not on workstation :) ). The bigger the company the more this makes sense to me. Anyone tried something like this? Are there any good practices? Any helpful software?

  • Problem in accessing Windows shared folder on Ubuntu using terminal

    - by vikramtheone
    Hi Guys, Description I have 2 systems with me, one running on Windows(Host) and one on Ubuntu, both on a LAN. On the Windows(Host) I develop software intended for the Linux system and because the Linux system has little external memory, my idea to overcome this is by making the project folder on the Host side a Shared Folder with full access and access it on Ubuntu over the network. To achieve this, I have installed Samba on Ubuntu, when I go to Places -> Network I can see the shared project folder and I simply mount it. A link appears on the desktop. Next, using Nautilus I open the link and I can access the contents of the shared folder. Problem Even though I mount the shared project folder, I don't see it appearing in the /media or the /mnt folder, as a result of this I don't know what path to use to access this folder, from the terminal. For example: When, I mounted my USB stick, as expected, a link for the device appears on the Desktop and I also see a folder in the media folder. So, similarly, a mounted shared folder should have appeared on the /mnt folder, too. Can anyone suggest what I should do now? There are many posts around, but no solid solution for this problem. Help!!! :) Vikram

  • Barriers to IPv6 deployment: addressing

    - by sysadmin1138
    There are several things that are keeping IPv6 deployment from being a topic of active discussion here at my work. There are the usual technical issues, but one non-technical one appears to be a major stumbling block on the path to actually getting a deployment project going. Addresses, memorizing of. Specifically, IPv4 addresses are comprehensible, and IPv6 addresses just look like a big long string of hex. The human mind has real trouble memorizing lists of more than 7-8 items, and an IPv4 address (192.168.231.148) has four items in it which makes it easy for us to memorize. A fully populated IPv6 address has not only 8 sections, but each section has 4 hex digits in it. IPv6 addresses were not designed for memorization. To the technician who knows that the DNS server is at 192.168.42.42 (or more likely "42.42", since the company prefix is likely memorized), the idea of memorizing an IPv6 address fills them with dread. Which in turn makes them much less enthusiastic about participating in an IPv6 deployment project. Because of how our network works we're not fully dynamic in terms of v4 addressing. We have several to many subnets that are entirely statically assigned for a variety of reasons, chief among them being that the overhead of static DHCP assignments is perceived as being too great. Also, some devices still aren't smart enough to pull DNS addresses out of DHCP while also having a static assignment, and therefore require manually configured DNS settings. Therefore, some v6 address memorization will have to be done. We're not under any mandate to get v6 out the door, so we don't have pressure from the top. However, it is time to start prepping our infrastructure to handle IPv6 even if we don't convert wholesale. For those of you who have been in IPv6-land for a while, what short-cut methods do you use to discuss or keep track of subnets and specific/critical IP addresses? If I can help reduce some of the dread surrounding IPv6 we might get the project going.

  • Time Machine vs Source Control?

    - by Blub
    Finally got convinced to start using some kind of version control for my code instead of zipping down a copy of the project at the end of each day. Downloaded Tortoise SVN and used it to create a repository localy on my hdd. I've been using it for 2 days now but I have to say that using it is actually more hassle than just copying the project manually in explorer. Sure, you only store incremental changes but with the cheap disks of today I can't really say that's an argument when you only have small projects. I haven't realy found a quick way to browse the older versions of my files eighter. What I want is an infinite undo that is completely transparent while I code, if I save the file I want a backup. I don't want to check out, check in and don't even get me started on moving files. I haven't tried Time Machine for OS X but it looks like it's exactly what I'm looking for. Does such a program exist for windows? Preferably free and with some kind of tagging-system so I can tag a timestamp when the project is working etc. Maybe should add that I mostly work alone on a single computer. Update: Some of you asked why I want backup. Since I work alone it's mostly to allow me to quickly hack up a solution without worrying that something will screw up.

  • Deploying a Django application in a virtual Ubuntu Server

    - by mfsaint
    I have a virtualbox machine running Ubuntu Server 10.04LTS. My intention is to this machine to work like a VPS, this way I can learn and prepare for when I get a VPS service. Apache+mod_wsgi for deploying the Django app seems the right choice to me. I have the domain (marianofalcon.com.ar) but nothing else, no DNS. The problem is that I'm pretty lost with all the deployment stuff. I know how to configure mod_wsgi(with the django.wsgi file) and apache(creating a VirtualHost). Something is missing and I don't know what it is. I think that I lack networking skills ant that's the big problem. Trying to host the app on a virtualbox adds some difficulty because I don't know well what IP to use. This is what I've got: file placed at: /etc/apache2/sites-available: NameVirtualHost *:80 <VirtualHost *:80> ServerAdmin [email protected] ServerName www.my-domain.com ServerAlias my-domain.com Alias /media /path/to/my/project/media DocumentRoot /path/to/my/project WSGIScriptAlias / /path/to/your/project/apache/django.wsgi ErrorLog /var/log/apache2/error.log LogLevel warn CustomLog /var/log/apache2/access.log combined </VirtualHost> django.wsgi file: import os, sys wsgi_dir = os.path.abspath(os.path.dirname(__file__)) project_dir = os.path.dirname(wsgi_dir) sys.path.append(project_dir) project_settings = os.path.join(project_dir,'settings') os.environ['DJANGO_SETTINGS_MODULE'] = 'myproject.settings' import django.core.handlers.wsgi application = django.core.handlers.wsgi.WSGIHandler()

  • Replacement for public folder workflow, I'm confused as to how sharepoint does it.

    - by RodH257
    For years Microsoft has been slowly phasing out public folders, perhaps exchange 2010 really is the LAST TIME they'll be shipped... I've heard sharepoint is the replacement, but I don't understand full, can someone give me an idea of how to replace this workflow? In our office, we have projects, they have a project number, ie 10353. Each job folder has a public folder, organized in a hierachy like Projects Year Folder Subfolders The main subfolder we use is for genera correspondence. When an email is received that relates to a project, it is dragged and dropped (or right click move to) a public folder. Adding public folder favourites for each user helps this. When an email is sent, we have a custom email form, which is the default email form, but with a project number field next to the subject line. When you enter the job number in there, it carbon copies our filing system in, which reads the job number and puts the email in the public folder for you. if you need to refer to emails, you go to public folder and find them there. This isn't the best with large jobs, but it works ok. Now, I have limited experience with sharepoint (well, WSS), we've used it to do some neat discussion boards/polls etc as an intranet site, but I haven't seen much of its integration with outlook. The great thing about our solution is how tightly it integrates with outlook which is exactly where the emails are. If you want to forward an old email, you go to public folder and forward it, simple. Any solution that replaces it should be at least as easy as this. Improvements we would like would be to have better searching of emails, better support in exchange (ie future version) and also, custom forms in outlook are being phased out (the VBA kind), so avoiding these would be good. Does sharepoint do this? or what solutions do this kind of thing?

  • Protect all XML-RPC calls with HTTP basic auth but one

    - by bodom_lx
    I set up a Django project for smartphone serving XML-RPC methods over HTTPS and using basic auth. All XML-RPC methods require username and password. I would like to implement a XML-RPC method to provide registration to the system. Obviously, this method should not require username and password. The following is the Apache conf section responsible for basic auth: <Location /RPC2> AuthType Basic AuthName "Login Required" Require valid-user AuthBasicProvider wsgi WSGIAuthUserScript /path/to/auth.wsgi </Location> This is my auth.wsgi: import os import sys sys.stdout = sys.stderr sys.path.append('/path/to/project') os.environ['DJANGO_SETTINGS_MODULE'] = 'project.settings' from django.contrib.auth.models import User from django import db def check_password(environ, user, password): """ Authenticates apache/mod_wsgi against Django's auth database. """ db.reset_queries() kwargs = {'username': user, 'is_active': True} try: # checks that the username is valid try: user = User.objects.get(**kwargs) except User.DoesNotExist: return None # verifies that the password is valid for the user if user.check_password(password): return True else: return False finally: db.connection.close() There are two dirty ways to achieve my aim with current situation: Have a dummy username/password to be used when trying to register to the system Have a separate Django/XML-RPC application on another URL (ie: /register) that is not protected by basic auth Both of them are very ugly, as I would also like to define a standard protocol to be used for services like mine (it's an open Dynamic Ridesharing Architecture) Is there a way to unprotect a single XML-RPC call (ie. a defined POST request) even if all XML-RPC calls over /RPC2 are protected?

  • Specify default group and permissions for new files in a certain directory

    - by mislav
    I have a certain directory in which there is a project shared by multiple users. These users use SSH to gain access to this directory and modify/create files. This project should only be writeable to a certain group of users: lets call it "mygroup". During an SSH session, all files/directories created by the current user should by default be owned by group "mygroup" and have group-writeable permissions. I can solve the permissions problem with umask: $ cd project $ umask 002 $ touch test.txt File "test.txt" is now group-writeable, but still belongs to my default group ("mislav", same as my username) and not to "mygroup". I can chgrp recursively to set the desired group, but I wanted to know is there a way to set some group implicitly like umask changes default permissions during a session. This specific directory is a shared git repo with a working copy and I want git checkout and git reset operations to set the correct mask and group for new files created in the working copy. The OS is Ubuntu Linux. Update: a colleague suggests I should look into getfacl/setfacl of POSIX ACL but the solution below combined with umask 002 in the current session is good enough for me and is much more simple.

  • How to continue an HTTrack mirroring session from the command line?

    - by isme
    I want to drive my mirroring project using the Command Prompt instead of the WinHTTrack interface so that I can script and schedule the mirroring session more easily. The output of httrack --help gives a simple command for continuing an interrupted mirroring session: example: httrack --continue continues a mirror in the current folder When I try httrack --continue in my HTTrack project folder, all I get is output like this: Example: -%F "<!-- Mirrored from %s by HTTrack Website Copier/3.x [XR&CO'2010], %s -->" * Option %F needs to be followed by a blank space, and a footer string With each parameter on a new line for readability, the first line of my doit.log file looks like this: -qiC1%P0s0b0u1j0%s%u0N0%I0p1DaK0c1T30H0%kf2E1800A25000%c0.1%f#f -F "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)" -%F "" -%l "en, en, *" http://saa.gov.uk/search.php?SEARCHED=1&SEARCH_TABLE=council_tax&SEARCH_TERM=City+of+Edinburgh&DISPLAY_COUNT=100 -O1 "C:\\Users\\Iain\\Projects\\Council Tax Analysis\\Code\\HTTrack\\Council Tax Valuation List" -* \ +*search.php?SEARCHED=1* -*DISPLAY_MODE=FULL* The parameter %F "" should tell HTTrack to use an empty footer. I used the WinHTTrack interface to create the project and start the mirroring session. I can interrupt and continue the mirroring session using the interface. The HTML files saved by WinHTTrack have no footer.

  • Folder with files shows as empty

    - by ProfKaos
    Last night I create a new project in Visual Studio 2010, in the folder c:\development\hobby\devices. When I navigate to that folder in a new instance of Windows Explorer, I get the 'This folder is empty.' message in the files pane. If I then, from within Visual Studio, issue the "Open containing folder command", explorer opens to the folder c:\development\hobby\devices\LoopBack, where loopback is a project under the main folder. If I paste that path into another new instance of explorer, explorer correctly opens c:\development\hobby\devices. How is this possible? SOLVED: This is what comes of typing paths instead of selecting them. Some elementary detective work yielded the following interesting results: C:\>dir dev*. Volume in drive C is OS Volume Serial Number is E4B4-0563 Directory of C:\ 2010/11/28 09:20 PM <DIR> Development 2010/12/01 08:57 PM <DIR> Develpment 2010/11/02 06:31 PM <DIR> DevTools 0 File(s) 0 bytes 3 Dir(s) 63 965 368 320 bytes free Where my disappearing project was in the badly spelt one.

  • How can I write an excel formula to do row based calculations; where certain conditions need to be met?

    - by BDY
    I am given: An excel sheet contains around 200 tasks (described in rows 2-201 in Column A). Each task can be elegible for a max of two projects (There are 4 projects in total, called "P1-P4" - drop down lists in Columns B and D); and this with a specific %-rate allocation (columns C & E - Column C refers to the Project Column B, and Column E refers to the Project in Column D). Column F shows the amount of work days spent on each task. Example in row 2: Task 1 (Column A); P1 (Column B) ; 80% (Column C) ; P3 (Column D) ; 20% (Column E) ; 3 (Column F) I need to know the sum of the working days spent on Project P3 respecting the %-rate for elegibility. I know how to calculate it for each Task (each Row) - e.g. for Task 1: =IF(B2="P3";C2*F2)+IF(D2="P3";E2*F2) However instead of repeating this for each task, I need a formula that adds them all together. Unfortunately the following formula shows me an error: =IF(B2:B201="P3";C2:C201*F2:F201)+IF(D2:D201="P3";E2:E201*F2:F201) Can anyone help please? Thank you!!

  • Visual Studio Code Analysis: CA0001 Error Running Code Analysis - object reference not set to an instance of an object

    - by sturdytree
    For a WPF application being developed in VS 2012 (Ultimate), the application runs fine when a particular project's code analysis is disabled. Enabling it results in the error above. This was working fine until recently (i.e. running with code analysis enabled for the particular project) and the only recent change I can think of is removing NHibernate Profiler (using NuGet). Will be grateful for any pointers on how to debug this, or to see a more detailed log/error message.

  • Creating an Objective-C++ Static Library in Xcode

    - by helixed
    So I've developed an engine for the iPhone with which I'd like to build a couple different games. Rather than copy and paste the files for the engine inside of each game's project directory, I'd a way to link to the engine from each game, so if I need to make a change to it I only have to do so once. After reeding around a little bit, it seems like static libraries are the best way to do this on the iPhone. I created a new project called Skeleton and copied all of my engine files over to it. I used this guide to create a static library, and I imported the library into a project called Chooser. However, when I tried to compile the project, Xcode started complaining about some C++ data structures I included in a file called ControlScene.mm. Here's my build errors: "operator delete(void*)", referenced from: -[ControlScene dealloc] in libSkeleton.a(ControlScene.o) -[ControlScene init] in libSkeleton.a(ControlScene.o) __gnu_cxx::new_allocator<operation_t>::deallocate(operation_t*, unsigned long)in libSkeleton.a(ControlScene.o) __gnu_cxx::new_allocator<operation_t*>::deallocate(operation_t**, unsigned long)in libSkeleton.a(ControlScene.o) "operator new(unsigned long)", referenced from: -[ControlScene init] in libSkeleton.a(ControlScene.o) __gnu_cxx::new_allocator<operation_t*>::allocate(unsigned long, void const*)in libSkeleton.a(ControlScene.o) __gnu_cxx::new_allocator<operation_t>::allocate(unsigned long, void const*)in libSkeleton.a(ControlScene.o) "std::__throw_bad_alloc()", referenced from: __gnu_cxx::new_allocator<operation_t*>::allocate(unsigned long, void const*)in libSkeleton.a(ControlScene.o) __gnu_cxx::new_allocator<operation_t>::allocate(unsigned long, void const*)in libSkeleton.a(ControlScene.o) "___cxa_rethrow", referenced from: std::_Deque_base<operation_t, std::allocator<operation_t> >::_M_create_nodes(operation_t**, operation_t**)in libSkeleton.a(ControlScene.o) std::_Deque_base<operation_t, std::allocator<operation_t> >::_M_initialize_map(unsigned long)in libSkeleton.a(ControlScene.o) "___cxa_end_catch", referenced from: std::_Deque_base<operation_t, std::allocator<operation_t> >::_M_create_nodes(operation_t**, operation_t**)in libSkeleton.a(ControlScene.o) std::_Deque_base<operation_t, std::allocator<operation_t> >::_M_initialize_map(unsigned long)in libSkeleton.a(ControlScene.o) "___gxx_personality_v0", referenced from: ___gxx_personality_v0$non_lazy_ptr in libSkeleton.a(ControlScene.o) ___gxx_personality_v0$non_lazy_ptr in libSkeleton.a(MenuLayer.o) "___cxa_begin_catch", referenced from: std::_Deque_base<operation_t, std::allocator<operation_t> >::_M_create_nodes(operation_t**, operation_t**)in libSkeleton.a(ControlScene.o) std::_Deque_base<operation_t, std::allocator<operation_t> >::_M_initialize_map(unsigned long)in libSkeleton.a(ControlScene.o) ld: symbol(s) not found collect2: ld returned 1 exit status If anybody could offer some insight as to why these problems are occuring, I'd appreciate it.

  • Where do all the old programmers go?

    - by Tony Lambert
    I know some people move over to management and some die... but where do the rest go and why? One reason people change to management is that in some companies the "Programmer" career path is very short - you can get to be a senior programmer within a few years. Leaving no way to get more money but to become a manager. In other companies project managers and programmers are parallel career paths so your project manager can be your junior. Tony
