  • in memory datastore in haskell

    - by Simon
    I want to implement an in memory datastore for a web service in Haskell. I want to run transactions in the stm monad. When I google hash table steam Haskell I only get this: Data. BTree. HashTable. STM. The module name and complexities suggest that this is implemented as a tree. I would think that an array would be more efficient for mutable hash tables. Is there a reason to avoid using an array for an STM hashtable? Do I gain anything with this stem hash table or should I just use a steam ref to an IntMap?

  • What stack of technologies should I use for my online game?

    - by Vee Bee
    I built a TicTacToe game to learn the .Net MVC3 framework. The basic functionality works (display board, make a move, detect winning move etc.) What I'd like to do is make it a "real" application - well-architected and using the right technology at the right layer. For instance, I'm currently saving every move to the database via a service call, which feels klugey and may become a bottleneck if this was an MMO game. How do you determine a good architecture (or right set of technologies) to use in a situation like this? I'd like to learn not just what to do, but why certain decisions are better than others. I noticed a similar thread here but it just offered opinions without explaining WHY something would be better (e.g. why Node instead of MVC3, etc.)

  • How to fix Bluetooth Sound in Ubuntu 11.10

    - by Cerin
    Bluetooth sound worked perfectly for me in Ubuntu 10.04. I recently upgraded to 11.10, and although sound in general works fine, Bluetooth sound almost never works. My headset is paired, and Sound Settings shows it's selected as the output device, but no sound is being output. I've tested the headset with other devices, and confirmed it still works, so the issue is definitely with 11.10. I'm not seeing any explicit errors and I can't find any similar issues with 11.10 through Google. I tried restarting the bluetooth service, but that had no effect. What can I do to fix this?

  • Unable to connect via Mobile Broadband - But its detected - 12.10

    - by Rexford
    Previously (on ubuntu 12.04), i will just connect my 3G mobile broadband modem, and will start browsing after enabling it and going through the setup process. However, on the 12.10, I'm able to setup my connection, but it doesn't connect to the internet. All settings are okay. I've tried two different network providers in Ghana, still, i'm not able to connect. At times, i'm notified that, its connected to the "home network" of the service provider, but disconnects in less than 10 seconds. Is it supposed to be a bug? I've been reading about the wvdial, but I'm wondering something that used to be possible by "default" in Ubuntu should now be "configured" via a software. Help!

  • What options are there for integrating with payment gateways? [closed]

    - by Rowland Shaw
    It seems that there are only two types of payment gateway service out there at the moment; Either that the entire cart logic is handled offsite (with something like Paypal's Standard option) or the other option being that you need to go through the certification for handling credit card numbers and doing pretty much everything yourself. Ideally, for the project I'm working on, I'm after a bit of middle ground such that I can handle the cart on-site, and only pass over to a payment gateway (with an order amount, billing & delivery details, and order ref) for them to handle the card details, before passing back. I'm sure that I've used e-commerce sites using this pattern before, but I cannot find any payment providers out there that offer this sort of option, so are there any? The only over requirement we have at present is that it must accept orders in Sterling.

  • Code to simulate a users actions, such as logging in

    - by Gortron
    I've recently begun working on a PHP application, replacing another developer. I believed the application was using an API to communicate with a remote service but when I looked through the code I found that it was using a set of functions to actually log in, fill out forms and submit them as a user might do in a browser. My intention is to replace this code, to use the services API instead. I've considered leaving the code as is and not replace it. It makes me wonder though is this a common practice in the software industry? To have a programme simulate a users actions in a browser to perform a set of actions? It feels to me that this is clever but poor programming, Have any other developers seen this?

  • Better control on code updates

    - by yes123
    I will briefly explain my situation. I have a website in PHP, this website is powered by a custom framework + some "plug-in" made ad hoc for it. I am the only developer of this. Until now I just test locally any changes than I upload the php files via FTP. I don't feel confortable anymore with this. The code base has grown quite a lot and I need some sort of system that helps to keep track of changes (line by line) and can restore to an old version easly if something goes wrong. Are there any good solution for this? Note: I never used something like version control or subversion because I think they are too much for this situation (I am the only developer and I just need basic feature) Note2: Something with a nice web interface would be perfect, I can pay for a good service too As now I found: http://beanstalkapp.com/ http://github.com/ http://www.codespaces.com/ http://codesion.com/ https://bitbucket.org/

  • Web api authentication techniques

    - by Steve
    We have a asp.net MVC web service framework for serving out xml/json for peoples Get requests but are struggling to figure out the best way (fast, easy, trivial for users coding with javascript or OO languages) to authenticate users. It's not that our data is sensitive or anything, we just want users to register so we can have their email address to notify them of changes and track usage. In our previous attempt we had the username in the URI and would just make sure that username existed and increment db tables with usage. This was super basic but we'd notice people using demo as a username etc so we need it to be a little more sophisticated. What authentication techniques are available? What do the major players use/do.

  • Switching hosting from Google Apps to GoDaddy

    - by Sahir M.
    I am in a pickle here. I just bought a hosting service from GoDaddy and I already have a domain registered with Google Apps. So I went into the domain control center from Google Apps and I changed the nameservers to point to GoDaddy's and then I deleted all the A records and also removed the www and main CNAME. Then I created an A record with host "@" which points to the IP address I got from GoDaddy (this is the server address I see under the category Server in the GoDaddy Hosting Control Center). Also, I see that in this domain center, the domain forwarding is set to forward to my address "www.domainsite.com". So right now when I go to my website I see the error "This website is temporarily unavailable, please try again later." Does anyone know how to set this up properly or know what problem I could be having? Thanks!

  • CS, SE, HCI, Information Science, Please recommendation for further education of the former performing art manager seeking career in IT industries? [on hold]

    - by Baek Seungjoo
    IT specialists there J Thank you very much for your collective efforts here, and I got huge help reading your professional comments and advices on each questions I have searched so far! This time, I would like to ask for your practical advices or recommendation on what I am struggling on at this moment. I am currently seeking higher education for my career transition from performing art manager and director to “IT software and/or service development and management specialist”. However, as this field is quite new to me, and there are lots of different work positions, I have no idea which grad major I better pursue in order to get qualification. Of course I know this question could sounds wired as it is kind of personal choice. But my lack of understanding on how IT software companies work in general, your practical and experience-based advice will be great help to me, who spent more than two months of self-research on net. OK. Before my question, here is my plan and history, which are quite different from those currently in IT industry I think… 1) Target Firstly, get career transition into IT service or products companies and get experiences. Eventually, pursue IT entrepreneurship in combination with my arts and cultural production and business expertise. 2) Background Career: performing arts director and manager in theatre-based scale opera and musical Art education in youth BA in literature and Chinese studies (Art & Humanities) MA in Cultural & Creative Industries (Art & Humanities) – dissertation with focus on digital prosumption and the lived experience of the prosumer. (a qualitative research on the agents in the digital world) 2) Personally Huge interest in IT hardware and software, and their trend. Skills to build up, repair, tune PCs -of course this is no more than personal hobby, but shows my interests in this field. 4) Problem Encounter a question “So, what do you think you can contribute practically in this position”. This question turn me down everytime I go through job interviews, and I decided more education in the relevant area. Here are my questions. 1) In terms of work positions in IT software companies, I wonder if I can put the comparison of what “Artists” is to “Arts Manager or Director” is what “Developer” is to “Product Manager”. (Of course, this stereotypical division of Artist-Art Manager is out of sense because the domain overlaps to some extent, and is blurring at least in my field, and they are in different contexts, but just speaking easily.) Normally, artist comes with special arts educations, and they live in their own world of artistic inspiration and creation, and they feel alive in practice and on stages. Meanwhile, from the point of staging and managing productions, the role of art manager is critical as well. Our role cares how the production appeals to the audience in effective way, how to make profit and future sustainable management through that, how to set up future strategy in consideration of the external conditions such as political and social circumstances, audience trend and level, other production trends from on-going and historical perspectives, how and what the production make voice to the society from political, economic, humanitarian stances. So, we need keen eyes on economic, political, and societal environment, have to understand human-being and their desires, must know how to make presentation and attract investors, must have sense in managing and fighting over the limited financial resource, how to extend networking and so on. It is common that the two agents create productions in collaboration (normally not in that ideal way but in conflict and fight though J ). So, we need to know each other’s expertise to some extent, for better production. What are the work positions in IT software industries equivalent to the role of “art manager” in performing arts? From my view, considering developers come with special education in the world of computer science, software engineering, or others (self-education sometimes), and they express themselves with the arts of coding, computer languages on the black screen, and make sort of their artistic production online to the audience, I guess there might be someone who collaborate with developers in creating, managing, and launching IT services or products. 2) Which education among CS, SE, HCI, Information Science, is needed for those seeking such work position? Especially for person like me. (At this moment, Information Science has the highest possibility to get in, since I lack Calculus and Math in undergrad educaiton. But please let me know irrespective of this concern, I think there are ways to back it up if CS or SE education needed in my case) 3) Which field between Information Science and HCI can be more practical background regarding job hungting? And which of them have more demands in job market? AS I checked, HCI is more close to CS than IS in its focus of study area. Thank you very much for your patience reading such a long inquiry, and I appreciate to your efforts in advance. Have a nice day in this beautiful summer.

  • How to solve dual monitor issue, which happens only during X start?

    - by tamashumi
    When is loading and two monitors are connected, instead of a login screen I see this: ...after clicking OK, selection appears: Then I'm following to console login, disconnecting by hand the secondary monitor cable, restart lightdm with a command sudo service lightdm restart ...and voila! System loads fine. If I disconnect the cable before boot X will be loaded fine too. It's not a nice 'feature' when I have to disconnect the cable each boot or X restart. I was trying to delete monitors.xml but it didn't help. The situation relates to my notebook with Intel integrated GPU. The same happens on two different pairs of monitors: at the office and at home. How can I fix this? Ubuntu 12.04 x64 Desktop with default Unity GUI.
