  • Should we be using JQuery for Mobile AJAX Page Navigation?

    - by Brad
    I am developing a mobile site that will load page content using AJAX if JavaScript is enabled. I have been using the JQuery load() functionality to load page contents from other static pages but I feel I am wasting precious bandwidth loading the entire JQuery library when I'm only using a small piece of it. With this said should we be avoiding libraries when only using small pieces of them?

  • include line numbers in stack trace without pdb?

    - by JoelFan
    We are currently distributing a WinForms app without .pdb files to conserve space on client machines and download bandwidth. When we get stack traces, we are getting method names but not line numbers. Is there any way to get the line numbers without resorting to distributing the .pdb files?

  • How to limit an upload speed in java servlet?

    - by den-javamaniac
    Hi. I'm working on an app (based on Spring as DI and MVC framework) that has a file upload function which is currently implemented using Spring Multipart Upload (which in it's turn utilizes commons fileupload libs). So what I'm looking for is a way to lower the upload bandwidth consumption. How can I accomplish that?

  • What is holding up HD video conferencing on the web?

    - by Tristan
    What exactly is holding up real-time HD video conferencing on the web? Live, low-latency, video has lots of great applications beyond video chat: for instance, virtual desktops / vnc, remote control of applications, and server-side visualization. So what exactly are the technical barriers that remain? Existing video and remote desktop applications show latency problems are overrated for many applications. Bandwidth for many users now can easily stream 720p and even 1080p. Top-end video conferencing demos already do 1080p

  • use AMF instead of JSON on iPhone?

    - by Henry
    Although iPhone support JSON natively, AMF is a binary protocol and it supposes to use much less bandwidth. Do you think using AMF is a good idea? Just found this AMF library in cocoa (Objective-C): http://github.com/nesium/cocoa-amf/

  • Why does Samba/CIFS suck so badly. [closed]

    - by sean
    Seriously, machines refusing to save data because files THEY HAVE OPEN are locked BY THEMSELVES. Getting 200+ connections simultaneously takes it out despite a plethora of available disk and network bandwidth. You can't turn off CUPS you have to COMPILE WITHOUT IT. DFS support is completely broken and pretty much useless in the current state (as in DFS for load balancing, not replication). We should just move to NFS and find a DFS like namespace aggregator.

  • Connecting private IPs

    - by Greg Roberts
    A friend of mine told me there was a way to connect two private IPs without using a proxy server. The idea was that both computers connected to a public server and some how the server joined the private connections and won't use any more bandwidth. Is this true? How's this technique named? Thanks

  • How many copies of files are needed by video server?

    - by Trilok
    A quick question. How many copies of the same movie are kept in a video server (a video streaming server)? Suppose a particular video is at max requested by 1000 users at the same instant of time, how many copies would be sufficient so that parallel streams can be provided to each user? Ideally 1 copy would solve the purpose, but what is the optimum number keeping the bandwidth and simultaneous access in mind?

  • What's holding up my PHP script?

    - by gAMBOOKa
    We've got a PHP crawler running on our web server. When the crawler is running, there are no cpu, memory or network bandwidth spikes. Everything is normal. But our website (also PHP), hosted on the same server, stops responding. Basically the crawler blocks any other php script from running. What could be the problem? EDIT: ** fsockopen is being used to download files to crawler! **

  • Mixing JQuery Ajax with ASP.NET : is there any security risk

    - by Sayem Ahmed
    I am using jQuery with ASP.NET in a project. Instead of using ASP.NET Ajax, I am using jquery's ajax functions. Is there any security risk if I do that? I mean, since I am using jquery's ajax calls, no view state information will be passed to the server so that it can verify the page's authenticity (though it saves a lot of bandwidth..). I would also like to know what is the best/good practice here.

  • gSOAP: How to send encrypted SOAP header

    - by Kangkan
    I want to send some info, like user credentials in the SOAP header from my gSOAP client to my WCF webservice. I wish I could send them in encrypted form. I am using GPRS to commuicate. As GPRS bandwidth is low, I don't want to use HTTPS. So I want to encrypt the header only. Is it possible? If yes, how? Please guide me.

  • What's a good video upload storage solution?

    - by Nikko
    What's a good video upload storage solution? I'm trying to find a way to offload bandwidth to another storage solution (something like S3), but at the same time, also trying to find a solution which is geared for video storage. Are there any solutions out there for this? Or should I just use S3? Thanks!

    - by Castor
    I generate htm files dynamically using php and .htaccess. I read somewhere that I should remove Etags for files of type text/html? Is that correct? I am wondering if I use etags and If i don't change the content, I could save some bandwidth. I would appreciate if you guys could tell me if I can use etags for htm files.

  • Should we have Browser Side Validation

    - by Raju
    For a back office application which is going to be used in house and users trained to use it, does it make sense to have browser side validation. After training users will seldom make mistakes. These mistakes would get caught at the server side. Also bearing in mind that the bandwidth availability is a lesser concern I feel we should avoid browser side validations. This will save the effort of maintaining the same functionality at two places.

  • set timeout to http response read method in python

    - by nirtayeb
    Hi, I'm building a download manager in python for fun, and sometimes the connection to the server is still on but the server doesn't send me data, so read method (of HTTPResponse) block me forever. This happens, for example, when I download from a server, which located outside of my country, that limit the bandwidth to other countries. How can I set a timeout for the read method (2 minutes for example)? Thanks, Nir.

  • Embedded "Smart" character LCD driver. Is this a good idea?

    - by chris12892
    I have an embedded project that I am working on, and I am currently coding the character LCD driver. At the moment, the LCD driver only supports "dumb" writing. For example, let's say line 1 has some text on it, and I make a call to the function that writes to the line. The function will simply seek to the beginning of the line and write the text (plus enough whitespace to erase whatever was last written). This is well and good, but I get the feeling it is horribly inefficient sometimes, since some lines are simply: "Some-reading: some-Value" Rather than "brute force" replacing the entire line, I wanted to develop some code that would figure out the best way to update the information on the LCD. (just as background, it takes 2 bytes to seek to any char position. I can then begin writing the string) My idea was to first have a loop. This loop would compare the input to the last write, and in doing so, it would cover two things: A: Collect all the differences between the last write and the input. For every contiguous segment (be it same or different) add two bytes to the byte count. This is referenced in B to determine if we are wasting serial bandwidth. B: The loop would determine if this is really a smart thing to do. If we end up using more bytes to update the line than to "brute force" the line, then we should just return and let the brute force method take over. We should exit the smart write function as soon as this condition is met to avoid wasting time. The next part of the function would take all the differences, seek to the required char on the LCD, and write them. Thus, if we have a string like this already on the LCD: "Current Temp: 80F" and we want to update it to "Current Temp: 79F" The function will go through and see that it would take less bandwidth to simply seek to the "8" and write "79". The "7" will cover the "8" and the "9" will cover the "0". That way, we don't waste time writing out the entire string. Does this seem like a practical idea?

  • Statistics of IMAP vs POP vs Exchange ?

    - by Antares
    Hello, I'm desperately looking for some statistics about usage of POP versus IMAP versus Exchange-MAPI, especially in professional context. I know IMAP is used for accessing mails from mobile devices with limited bandwidth, whereas POP is the good old standard, and Exchange is more business-oriented. Does someone know the approximate percentage of usage of each protocol ? Thanks !

  • Hidden limitations of Google App Engine?

    - by Kyle Cronin
    I've been looking into writing a web app that will run on Google App Engine, but before I commit myself to the platform I'd like to know what, if any, limitations there are. I'm aware of the basic CPU/bandwidth restrictions that Google places on the free service, but I'm wondering more about development restrictions like how BigTable compares to a standard relational database and what Python libraries aren't available on the GAE platform (and what alternatives Google provides). Basically I'm looking for any hidden roadblocks before I commit to the platform. Thanks for your help!
