  • Future of IE9: Opacity + Performance

    - by chris_l
    I just tried the IE9 "Second Internet Explorer Platform Preview" - which supports CSS opacity now. That's nice, but I tried it with one of my website prototypes, and it's quite slow when scrolling etc. Admittedly, the prototype uses hundreds of images with opacity != 1, but everything is snappy with current versions of Firefox, Safari, Chrome and Opera. Does anybody know, if there are plans for IE9 to become faster in this area? Even rumours about this would be interesting in this case.

    - by Agito
    I am working on a solution, most of its core engine is developed as Win32 C++ (and is Platform independent and is also used on OS X), some time ago we needed to call C++ dll's of core engine from C# and I was able to Load main solution's DLL in C# (by the help of some threads here on SO). but now we have certain things implemented in Managed C# dll and need to use it in Win32 C++ project? (and just function definitions and dll are provided)

  • Expire models in Rails

    - by Koning Baard XIV
    I'm creating a simple paste-bin in Ruby on Rails, which will have an expire-feature. With this, people can select a date when the paste will be deleted automatically. How can I implement this? I was thinking of a cronjob, but maybe there is a more platform-independent way, by defining this in the model itself. Can anyone help me? Thanks.

  • Apache on Windows in production environment? Why not?

    - by tillda
    "Everyone" know that Apache is for Linux/Unix and on Windows IIS is the way to go. However, I'm not a pro at Linux and it would be an enormous relief for me to use just the same setup in the production environment that I use during development. I'm a solo developer and I'm trying to make things as simple as possible. I've already got rid of other issues like storage (-cloud) emails (-postmark). So, what are the real drawbacks that can happen when I just put Apache in Windows virtual private server from Rackspace and use it as the main production environment for a PHP project? Money for more VPS resources is not that big issue compared to the possibility of not having to learn a different OS. Super-heavy traffic is not expected. Also my PHP project can be quite optimized. There are some heavy scripts, but only for the inside (logged) users. All else can be served more or less statically.

  • What would Stack Exchange's yearly expenses be if it were to be using a third party host?

    - by abel
    StackExchange manages it's own servers, as it should, but if SE were to be hosted on a 3rd party "cloud" hosting (like Amazon's), what would it's monthly / yearly expenses be(keeping everything else the same)? A detailed answer comparing it to the bills that Stackexchange boots currently (including power/property/staff) would help. (PS: I know that the blog is a good resource. I also understand that managing your own hosting is almost the same as setting up a hosting company and using it for your own needs. Plus is this a question for meta or does it fit within serverfault's purview?)

  • How to treat 64-bit words on a CUDA device?

    - by pikkio
    Hi, I'd like to handle directly 64-bit words on the CUDA platform (eg. uint64_t vars). I understand, however, that addressing space, registers and the SP architecture are all 32-bit based. I actually found this to work correctly (on my CUDA cc1.1 card): __global__ void test64Kernel( uint64_t *word ) { (*word) <<= 56; } but I don't know, for example, how this affects registers usage and the operations per clock cycle count.

  • Chrome to download Gmail attachments to a different place

    - by Joe
    I'm using Chrome and Gmail. When I download stuff from the web, Chrome automatically puts it in Downloads, which is fine. However, I'm aware that everything I download from Gmail is in the cloud anyway and so I don't really need it taking up space on my hard drive as well. Is there a way to have Gmail attachements automatically download to a different folder, say, Downloads\Gmail? That way I could regularly purge the ones that won't be useful for a while. (Yes, I'm aware that Word documents and the like often get changed after they arrive, I'm more focused on images, pdfs, and zip files.)

  • Do null SQLite Data fields take up extra memory?

    - by CSharperWithJava
    I'm using the built in sqlite library on the Android platform. I'm considering adding several general purpose fields that users will be able to use for their own custom applications, but these fields will be blank most of the time. My question is, how much overhead will these blank fields add to my database? Do null fields even take up per record memory in sqlite? If so, how much? I don't quite understand the inner workings of a sqlite database.

  • KVM guest storage difference with NBD and NFS

    - by WojonsTech
    I am setting up my own little private cloud for my own use maybe for a project or to. I am using linux kvm on debian 6. I have 3 servers 2 of them for compute nodes and 1 storage node. I would I have already installed kvm made a few test machines got my networking setup. I have 2 nics on each server 1 nic is for web traffic other nic is for network traffic. My first Idea was to use NFS for storing the guest machines which can range in size, maybe 8gb maybe 100gb, it just depends. I was doing have heard of nbd before seems like it could work but I dont know what the performance differences are and if it will effect my enviroment, nfs looks like it will be easier to use.

  • The Relationship Between Activities and View Objects - Android

    - by Greenhouse Gases
    I am attempting to learn how to develop on the Android platform but do not quite understand the relationship between Activities and Views, because according to the documentation an Activity is link to a UI object that the user can interact with, but if this is the case where does the whole idea of Views come in? There is probably a very basic explanation but I would appreciate a few pointers all the same. Thanks

  • Can I rent exclusive time on a powerful server running linux? [closed]

    - by Mark Borgerding
    My company is involved in a proposal that requires speed estimates of our software on a server with the latest & greatest processors. This is not the first time we've been in this situation. The servers themselves are too expensive to buy a new one every time, so we end up extrapolating from what we have. There are so many variables: processor generation & speed, memory speed, memory channels, cache configurations; it makes extrapolation difficult and error-prone. Is there a business that rents time on the newest servers? At least part of the time we'd need exclusive access to an otherwise quiescent system either via ssh shell access or unattended batch jobs. I am not looking for general cloud computing services. I don't need much time on the server, but it needs to be exclusive. And the server needs to be pretty cutting edge for a solid basis of estimate.

  • Breaking out of the Google App Engine Python lock-in?

    - by Alterlife
    Are there any guidelines to writing Google App Engine Python code that would work without Google's infrastructure on other platforms? Is there any known attempt to create an open source framework which can run applications designed for Google App Engine on other platforms? Edit: To clarify, the question really is: If I develop an application on Google App Engine now, will I be able to migrate to another platform later, or is it a lock in?

  • Is disabling password login for SSH the same as deleting the password for all users?

    - by Arsham Skrenes
    I have a cloud server with only a root user. I SSH to it using RSA keys only. To make it more secure, I wanted to disable the password feature. I know that this can be done by editing the /etc/ssh/sshd_config file and changing PermitRootLogin yes to PermitRootLogin without-password. I was wondering if simply deleting the root password via passwd -d root would be the equivalent (assuming I do not create more users or new users have their passwords deleted too). Are there any security issues with one approach verses the other?

  • Automatic Server Management

    - by Radoslav
    I try to find any kind of automatic management services. What I mean: I purchase dedicated server. Login SSH and install any kind of Daemon. Control security, tune LAMP stack, monitoring etc. from dashboard. Never touch SSH and login in to the server. Pay every month for this service. I already find few providers, but they support only EC2 cloud servers. If you can suggest me anything for dedicated machines? If not- I need to hire anyone for 5h Administrator and 715h "Box-Watcher" every month :|
