Any advice? Thanks.

  • Solution for distributing MANY simple network tasks?

    - by EmpireJones
    I would like to create some sort of a distributed setup for running a ton of small/simple REST web queries in a production environment. For each 5-10 related queries which are executed from a node, I will generate a very small amount of derived data, which will need to be stored in a standard relational database (such as PostgreSQL). What platforms are built for this type of problem set? The nature, data sizes, and quantities seem to contradict the mindset of Hadoop. There are also more grid based architectures such as Condor and Sun Grid Engine, which I have seen mentioned. I'm not sure if these platforms have any recovery from errors though (checking if a job succeeds). What I would really like is a FIFO type queue that I could add jobs to, with the end result of my database getting updated. Any suggestions on the best tool for the job?

  • how can i find unused css in ajax app?

    - by Haroldo
    I've been searching and i can't find any ff addons or javascript for finding unused css in ajax apps. dust-me selectors can do a site-crawl, but i'm looking for something that examines loaded-in content... I'd like something where i can press 'record' and then make a load of clicks which will check off the used selectors, and hoping to find an existing one rather than try to write my own with jquery!

  • Sinatra/Rails: Persisting custom class instances during app lifetime

    - by knoopx
    Can I assert rails/sinatra apps are initialized only once and all requests share the same app instance? or do new requests spawn new app instances? Is it possible to instance custom classes and persist them during app lifetime without using sessions, database storages or third party services? If so, what are the implications from a thread-safeness point of view? I'm trying to figure how to implement a web-based download manager and I'm currently evaluating ruby-based frameworks.

  • Redmine & Git integration

    - by archnemesis
    I am considering moving from svn and Trac to git and Redmine. I'm just wondering what everyone's experience is of this. How well does git integrate with Redmine? I'm pretty set on my decision to change from svn to git - our distributed work, and need to frequently branch and merge would make life considerably easier with git. But we would possibly need to split things into multiple projects for this. From what I have been reading, git and multiple projects don't integrate too smoothly with Trac. That aside, in my investigations into git, Redmine has also caught my attention, and some of the features look very useful. However, I haven't found as many user experiences of git and Redmine as what I'd like (possibly due to my lack of searching skills...) and so would like to hear your opinions and examples.

  • even small file upload stops activity on apache/rails

    - by Pavel K.
    on my rails(2.3.5) app(currently 50-70rpm, maximum response time around 0.7s), uploading even 700k file(using paperclip plugin) locks up the server for web requests for everyone for 2 minutes! (other apps on same server work normally) does anyone have a clue why that might be happening? i am using some mysql transactions which lock the database also if that might be an issue i read http://www.therailsway.com/2009/4/23/uploading-files but it couldn't be locking server for 2 minutes for a small file, could it?!

  • Help regarding no sql databases like hadoop, hbase etc

    - by user560370
    I am new to the distributed NoSQL databases like Hadoop, Cassandra, etc. I have few questions for which I seek an expert advice: Can you list problems/challenges one will generally face when making a shift from the present conventional database like MySQL to these large cluster-based databases? What are the difficulties, if any, when one needs to adapt to a newer version of these open source projects? Can you list out the things which are generally stored/kept in memcached for fast rendering of the page? How can I understand the source code of open-source projects so that I can build on it and maybe give back to the community? Above questions may sound to be idiotic and basic but please it's a request for the experts to answer the above questions in detailed and to best of their abilities.

  • Giving proper credit to a projects contributors

    - by Greg B
    I've recently been working with an opensource library for a commercial product. The opensource code is distributed from the website of the company who sells the proprietary product as a zip file. The library is a (direct) port to C# of the original library which is in Java. As such, it uses methods instead of getter/setter properties. The code contains copyright notices to the supplier of the product. The C# port was originally provided to the company by a 3rd party individual. I have modified the source to be more C# like and added a couple of small features. I want to put my version of the code out there (Google code or where ever) so that C# users of the software can benefit from a more native feeling library. How can I and/or how should I amend the copyright notice to give proper credit to The comercial owner of the original source The guy who provided the original C# port Myself and anyone else who contributes to the project in the future The source is provided under the LGPL V2.1,

  • Exhaustive (or even just large) list of languages/stacks used for popular sites?

    - by jacko
    As a result of a conversation with a colleague today, I've been searching (unsuccessfully) for a large'ish list of what technology stacks are being used popular websites and standalone applications today. We're aware of the big ones like Facebook (php/ ), Twitter (scala/cassandra), Youtube (python/?), Digg (php/cassandra), stackoverflow (.net mvc/sqlserver), but we're looking for a more complete list. It would also be interesting to hear about any stats for desktop apps also? Can anyone help?

  • memcached cluster maintenance

    - by Yang
    Scaling up memcached to a cluster of shards/partitions requires either distributed routing/partition table maintenance or centralized proxying (and other stuff like detecting failures). What are the popular/typical approaches/systems here? There's software like libketama, which provides consistent hashing, but this is just a client-side library that reacts to messages about node arrivals/departures---do most users just run something like this, plus separate monitoring nodes that, on detecting failures, notify all the libketamas of the departure? I imagine something like this might be sufficient since typical use of memcached as a soft-state cache doesn't require careful attention to consistency, but I'm curious what people do.

  • Is it OK to try to use Plinq in all Linq queries?

    - by Tony_Henrich
    I read that PLinq will automatically use non parallel Linq if it finds PLinq to be more expensive. So I figured then why not use PLinq for everything (when possible) and let the runtime decide which one to use. The apps will be deployed to multicore servers and I am OK to develop a little more code to deal with parallelism. What are the pitfalls of using plinq as a default?
