• hosting environment for delivering FLVs [closed]

  - by Gotys

  What would be the ideal hardware setup for pushing lots of bandwith on a tube site? We have ever-expanding cloud storage where users upload the movies, then we have these web-delivery machines which cache the FLV files on its local harddrives and deliver them to users. Each cache machine can deliver 1200 mbits/s , if it has SAS 8 harddrives. Such a cache machine costs us $550/month for 8x160gb -- so each machine can cache only 160GB at any given time. If we want to cache more then 160gb , we need to add another machine..another $550/month..etc. This is very un-economical so I am wondering if we have any experts here who can figure out a better setup. I've been looking into "gluster FS", but I am not sure if this thing can push a lot of bandwith. Any ideas highly appreciated. Thank you!

• cakePHP paginate with post data without sessions, serialization or post to get

  - by openprojdevel

  I have created a small search and filter form method post in controller/index, which posts to it self the conditions and fields to paginate ( $this-paginate($conditions) ) However that is good for the first page, the subsequent pages the filer conditions are lost. pagination passArgs supports get variables well. Is there an un complex way to pass the post conditions to the other paginated pages? The method I have looked at is pass the $conditions in session , which isnt without complexity of assigning session and unset the session on submitting the form again (more refinements to the filter criteria by the user ) The other method is passing the $conditions as serialized string url_encode as an get parameter. Is there an good cake way to do this more like passArgs, sessions and url encode do not look like cake style. Thanks

• UISearchBar Above Navigation Bar

  - by JonB

  Hi, All the applications I have ever seen, that use UINavigationBars, have the UINavigationBar right at the top of the app. If you want to use a UISearchBar then it's usually in the 'header' of the UITableView such as this... What I would like to do is to put a UISearchBar object above/outside of the UINavigationBar/Controller, but i've been having some problems doing this. Firstly, is what I want to achieve even possible? What would the easiest way to do this be? Starting with the navigation based application seems to make the navigationbar/view un-resizeable! Thanks, Jon

• Removing the image from an IKImageView

  - by Brian Postow

  I have an IKImageView that is coming up effectively un-initialized. This is happening effectively in an error-state (The user is unregistered) so I haven't had a chance to put an image in it yet. In 10.6, this comes up fine, with a black rectangle. In 10.5, however, it comes up with garbage. some rectangles of noise, some rectangles of copies of the desktop, etc. I've tried setting the ZoomFactor to 0.0, I've tried setting the image to nil, but it appears that the problem is beyond that. any ideas? (My next kludge is going to be to ship tiny blank image with the app, and try to get it to load that... but that's kind of silly)

• Can I redistribute Phing with non-free software?

  - by Matt1776

  I am having trouble understanding the terms of the LGPL in light of a program that is not written in C or C++. They speak of libraries being linked and 'derivitive' works. If I were to package a php program and sell it, but within the program the deployment mechanism used the phing package (full up with the entire contents as is and un modified) - would I be violating the terms of the LGPL? For example, If this was a C program that was compiled by linking the phing 'library' then the answer would be easier, it is a derivitive work and therefore unless released under the GPL will not be considered free and also a violation. But this situation is different. I am not linking and not producing a derivitive, i am simply using phing as a deployment tool to move files around and set up the enviornment. Can someone shed some light? Thank you!

• restore default css attributes

  - by pstanton

  hi all. i'm writing a component that is to be used across multiple websites. each website has it's own stylesheets and displays certain things differently. all of my html is wrapped within a div with an id: <div id="myComponent">...</div> my component however is to look consistent across all of the sites. this is fine as i apply styling to most of the attributes in my component. div#myComponent p {font-size:11px;} etc however i've come across a site that removes the border from all input fields input {border: medium none;} i need to 'un-apply' this directive for the input fields within my component, and preferrably use the browser's default styling for inputs, as the border style for input type="text" will need be different to input type="button". how would you achieve this?

• Split ExtJS for incremental (on demand) download.

  - by Kabeer

  Hello. I had earlier asked whether I can remove un-utilized JavaScript code from ExtJS library. JSBuilder was the answer. What about being able to download widgets on-demand? I ask this because I have discovered this from the of markup generated by Coolite (ASP.Net framework that wraps ExtJS). So do I have to go through a meticulous process of splitting the library myself or is there a better way? BTW I'd like to avoid using Coolite.

• Populate JSP dropdown with database info

  - by Cano63

  I'm looking for the way to populate a JSP dropdown. I want that when the JSP loads it fills the dropdown with the info that I have in a database table. I'm including the code of my class that will create the array and fill it with the database info. What I don't know is how to call that class from my JSP and fill the dropdown. // this will create my array public static ArrayList<DropDownBrands> getBrandsMakes() { ArrayList<DropDownBrands> arrayBrandsMake = new ArrayList<DropDownBrands>(); while (rs.next()) { arrayBrandsMake.add(loadOB(rs)); // CARGO MI ARREGLO CON UN OBJETO } return arrayBrandsMake; } // this will load my array object private static DropDownBrands loadOB(ResultSet rs) throws SQLException { DropDownBrands OB = new DropDownBrands(); OB.setBrands("BRAN"); return OB; }

• image archive VS image strip

  - by DevA

  Hi, i've noticed that plenty of games / applications (very common on mobile builds) pack numerous images into an image strip. I figured that the advantages in this are making the program more tidy (file system - wise) and reducing (un)installation time. During the runtime of the application, the entire image strip is allocated and copied from FS to RAM. On the contrary, images can be stored in an image archive and unpacked during runtime to a number of image structures in RAM. The way I see it, the image strip approach is less efficient because of worse caching performance and because that even if the optimal rectangle packing algorithm is used, there will be empty spaces between the stored images in the strip, causing a waste of RAM. What are the advantages in using an image strip over using an image archive file?

• Subclipse plugin doesn't work in Eclipse?

  - by blackicecube

  Hi, even though there was no error when installing Subclipse in Eclipse. I won't see the SVN perspective at all? I have tried with "Eclipse Classic 3.5.1" and with "Eclipse for PHP Developers". After downloading and unzipping the packages I used Eclipse's "Install Software" mechanism to install Subclipse 1.6.x. I followed the steps described here: http://www3.math.tu-berlin.de/jreality/mediawiki/index.php/Subclipse_installation_in_eclipse_galileo. But after Eclipse re-starts I don't get any SVN Repository perspective? I have tried to un-install/re-install all the software components many times now. Finally after 3 hours of trying I am giving up. Does anyone have any hint what I am missing? Thanks! Peter

• Web/HTML: how do referrer work technically?

  - by NoozNooz42

  I don't understand how comes webserver and trackers like Google Analytics are able to track referrals. Is it part of HTTP? Is it some (un)specified behavior of the browsers? Apparently everytime you click on a link on a webpage, the original webpage is passed along the request. What is the exact mechanism behind that? Is it specified by some spec? I've read a few docs and I've played with my own Tomcat server and my own Google Analytics account, but I don't understand how the "magic" happens. Bonus (totally related) question: if, on my own website (served by Tomcat), I put a link to another site, does the other site see my website as the "referrer" without me doing anything special in Tomcat?

• How to make a UserControl with a custom DefaultBackColor?

  - by Blorgbeard

  When I right-click on my custom UserControl's BackColor property in the property-grid, then click Reset, I would like the BackColor property to change to (for example) Color.LightGreen, and the property value to appear un-bolded, to indicate that it is the default value. Currently, I know I can do this: public override void ResetBackColor() { BackColor = Color.LightGreen; } Which works as far as setting it to LightGreen on reset. But it still appears bolded in the property-grid, indicating that the current value is not the default. I notice that the Control class has a static read-only property, DefaultBackColor. Unfortunately, since it's static, I cannot override it. Is there some way to get all the functionality I want?

• Jquery username check

  - by Sergio

  I'm using this Jquery function for available username check. How can I fire this Jquery function only if the username field is greater of 5 characters? Jquery looks like: $(document).ready(function() { $('#usernameLoading').hide(); $('#username').blur(function(){ $('#usernameLoading').show(); $.post("usercheck.php", { un: $('#username').val() }, function(response){ $('#usernameResult').fadeOut(); setTimeout("finishAjax('usernameResult', '"+escape(response)+"')", 400); }); return false; }); }); function finishAjax(id, response) { $('#usernameLoading').hide(); $('#'+id).html(unescape(response)); $('#'+id).fadeIn(); } //finishAjax Can I use something like this and how: var usr = $("#username").val(); if(usr.length >= 5) { }

• What does this suspicious phishing code do?

  - by halohunter

  A few of my non-IT coworkers opened a .html attachment in an email message that looks extremely suspicious.

• What is the bit size of long on 64-bit Windows?

  - by acidzombie24

  Not to long ago someone told me that long are not 64 bits on 64 bit machines and i should always use int. This did not make sense to me. I seen docs (such as the one on apples official site) say that long are indeed 64 bits when compiling for a 64bit CPU. I looked up what it was on windows and found Windows: long and int remain 32-bit in length, and special new data types are defined for 64-bit integers. from http://www.intel.com/cd/ids/developer/asmo-na/eng/197664.htm?page=2 What should i use? should i define something like uw, sw ((un)signed width) as a long if not on windows. Otherwise do a check on the target CPU bitsize?

• Direct2D window black when not in focus

  - by Saul Rennison

  Hi all, I have a Direct2D window which paints fine when in focus; however, when focus moves to another window (same application or another), the entire window goes black. I pinned the issue down to the use of ID2D1HwndRenderTarget::Clear. This function is vital to my application as without it, painting becomes rather... weird. Is there a way an un-focused Direct2D window can paint as normal (note: WM_PAINT is being called as usual, as is Clear, BeginPaint, etc. all without error) Thanks in advance.

• How to decompress/inflate an XML response from ASP

  - by krisg

  Can anyone provide some insight into how i'd go about decompressing an XML response in classic ASP. We've been handed some code and asked to get it working: Set oXMLHttp = Server.CreateObject("MSXML2.ServerXMLHTTP") URL = HttpServer + re_domain + ".do;jsessionid=" + ue_session + "?" + data oXMLHttp.setTimeouts 5000, 60000, 1200000, 1200000 oXMLHttp.open "GET", URL, false oXMLHttp.setRequestHeader "Accept-Encoding", "gzip" oXMLHttp.send() if oXMLHttp.status = 200 Then if oXMLHttp.responseText = "" then htmlrequest_get = "Empty Response from Server" else htmlrequest_get = oXMLHttp.responseText end if else ... Apparently now that the response is compressed using gzip, we have to un-compress the XML response before we can start to work with the data. How should i go about this?

• Hosting a complex online service

  - by jonathanconway

  I have an idea for a web-based service. The implementation is very complex. There will be very few users, and the traffice will be fairly low, but the server-side code could require a lot of resources. Ideally I'd need to have as much control over the servers as possible. How should I arrange hosting for this, when it comes time to release it to the public? Should I do the hosting myself, from my own servers? Trouble is, since I'm not quite an expert on .NET hosting, it might take time to learn and I might make big mistakes. The trouble with using a hosting company is, they might steal my idea, or else, it might cost a lot. Since I'm an un-funded startup I don't have a lot of money to throw at this.

• Is it possible to resize a SpriteAsset without adding it to the display list?

  - by Sophistifunk

  Hi guys, I have an embedded image asset (with a scale9 grid), and I'm trying to get the bitmapdata when it's resized, but I can't seem to do this without adding it to the display list. I try this: spriteAsset.setActualSize(w,h); spriteAsset.width = w; bmd.draw(spriteAsset); But when I then draw out the bitmapdata with graphics.beginBitmapFill(), I just get the original un-stretched image. Any pointers? Or do I need to take 9 separate BitmapData images and make 9 separate bitmap fills? Cheers, -Josh

• What skills are needed to be successful at robotics?

  - by Click Upvote

  I'm considering studying to be a robotics engineer. The desire to work in that field is definitely there.. but I'm wondering what my chances of success would be. Generally I'm good with mental tasks of any sort such as programming, maths, physics, etc, and I think i'd be able to do electrical work such as soldering wires, changing batteries, etc. However, I'm not so good with things of a physical nature where I have to use my hands. For example, if you give me some vegetables to slice and dice, all of them will be diced un-evenly and some will look ugly. This might be because I have poor mind-hand coordination or because of a lack of concentration. Thoughts?

• Scala Lift - Robust method to protect files from hotlinking

  - by sirjamm

  I'm attempting to implement a way to stop hotlinking and/or un-authorised access to resources within my app. The method I'm trying to add is something I've used before in PHP apps. Basically a session is set when the page is first called. The images are added to the page via the image tag with the session value as a parameter: <img src="/files/image/[handle]?session=12345" /> When the image is requested the script checks to see if the session is set and matches the provided value. If the condition is not met the serving page returns null. Right at the end to the code I unset the session so further requests from outside the scope of the page will return null. What would be the best implementation of this method within the lift framework? Thanks in advance for any help, much appreciated :)
