• I know this is a stupid question but... How many websites can my server potentially hold?

  - by Daniel Kindler

  Sorry for the "noob" question, but... About how many medium-sized websites with average traffic could this server hold? Just like the average website, kind of like a small business site. How many sites could this server hold, but still maintain nice, decent speed?

• IE Information Bar, download file...how do I code for this?

  - by flatline

  I have a web page (asp.net) that compiles a package then redirects the user to the download file via javascript (window.location = ....). This is accompanied by a hard link on the page in case the redirect doesn't work - emulating the download process on many popular sites. When the IE information bar appears at the top due to restricted security settings, and a user clicks on it to download the file, it redirects the user to the page, not the download file, which refreshes the page and removes the hard link. What is the information bar doing here? Shouldn't it send the user to the location of the redirect? Am I setting something wrong in the headers of the download response, or doing something else wrong to send the file in the first place? C# Code: m_context.Response.Buffer = false; m_context.Response.ContentType = "application/zip"; m_context.Response.AddHeader("Content-Length", fs.Length.ToString()); m_context.Response.AddHeader("Content-Disposition", string.Format("attachment; filename={0}_{1}.zip", downloadPrefix, DateTime.Now.ToString("yyyy-MM-dd_HH-mm"))); //send the file

• Why does Resource Monitor in windows 7 show half my memory as "Hardware Reserved"?

  - by Brandon

  Does anyone know why in Windows 7 Resource Monitor shows that I have 8 GB of RAM installed on my computer, but I only have 3.2 GB available as 4.8 GB are in "Hardware Reserve". I researched this issue and tried going into msconfig and making sure that in the boot options the number of processors and max memory options were turned off. I also opened the computer up and reseated each of the memory sticks while clearing out any dust that was in there. Some info on the system I am using: OS: Windows 7 Enterprise 64-bit Edition CPU: AMD Phenom X4 9750 Memory: 4 X 2GB DDR2 memory Motherboard: MS-7548 (Aspen) Any help would be much appreciated.

• Time of splitting and encoding video with ffmpeg increases exponentially

  - by Rnd_d

  I'm trying to split video by subtitles and encode into .mp4(h.264/aac) using ffmpeg, but it takes so much time! First pieces of video are splited and encoded really fast, but for each iteration time increases, and so 40 min video takes all night or more. Small 3 min video takes max 10 mins. cmd for splitting and encoding: ffmpeg -i filename.avi -ss 00:00:0(time of sub start) -t 0:0:3(time of sub duration) -acodec libfaac -vcodec libx264 -bf 0 -f mp4 filename.mp4 ffmpeg version N-34849-g07c7ffc (last, i think) How I can make it faster? Are there, maybe, some magic arguments for ffmpeg or some hacks?

• How lucene indexing ?

  - by user312140

  Hello I read some document about lucene ; also i read the document in this link ( http://lucene.sourceforge.net/talks/pisa ) . I don't really understand how lucene index documents and don't understand lucene work with which algorithm for indexing ? On above link , said lucene use this algorithm for indexing : * incremental algorithm: o maintain a stack of segment indices o create index for each incoming document o push new indexes onto the stack o let b=10 be the merge factor; M=8 for (size = 1; size < M; size *= b) { if (there are b indexes with size docs on top of the stack) { pop them off the stack; merge them into a single index; push the merged index onto the stack; } else { break; } } How this algorithm help us to have an optimize indexing ? Does lucene use B-tree algorithm or any other algorithm like that for indexing or have a paticular algorithm ? Thank you for reading my post .

• Is 50% download speed on a wireless G network normal?

  - by Bartlomiej Skwira

  I have a wired connection of about 36Mb/s, but my wireless speed is max at about 18-19Mb/s. I have a WRT54G-TM (T-Mobile, 802.11G) router with DD-WRT firmware - I've upgraded it to latest build. Done some settings changes: changed channel - 13 wireless network mode - G-only ACK Timing - 0 Fragmentation Threshold and RTS Threshold - 2304 Basic Rate - All Signal/Noise ratio: -46/-94, signal quality ~50-60%. Is this normal with G networks? Edit: The AP is located about 2 meters from laptop, no walls or metal objects, but its next to a TV. I've done a channel scan (had problems locating it, go to "Status - Wireless - Site survey" - lame naming) and everybody else is on channels 1 and 6. Switched to channel 11 but it didn't help. As for trasmit power I got best results with default 71mw. The antenna might be a factor, I'm using the default 2 antennas.

• How to hide an dom element after creating it on the fly with Jquery ?

  - by ismaelsow

  I am trying to build a form where users can add a text field by clicking on a "add option" button. They can also remove added fields by a "remove option" link created on the fly by Jquery, along with the text field. My code looks like this : $(document).ready(function(){ $("#add_option").click(function(){ var form = $("form"); var input_field = '<input type="text" />'; var delete_link = '<a href="#">remove</a>'; form.append(input_field + delete_link); return false; }); $("a").click(function(){ alert('clicked'); return false; }); }); This code is not working : when I click on the "add_option" button, a new text field and the "delete_link" appear. But when clicking on the "delete_link" created by JQuery, the browser follows the link instead of launching a pop-up displaying "clicked". Any idea ? Thanks !

• Convert a binary tree to linked list, breadth first, constant storage/destructive

  - by Merlyn Morgan-Graham

  This is not homework, and I don't need to answer it, but now I have become obsessed :) The problem is: Design an algorithm to destructively flatten a binary tree to a linked list, breadth-first. Okay, easy enough. Just build a queue, and do what you have to. That was the warm-up. Now, implement it with constant storage (recursion, if you can figure out an answer using it, is logarithmic storage, not constant). I found a solution to this problem on the Internet about a year back, but now I've forgotten it, and I want to know :) The trick, as far as I remember, involved using the tree to implement the queue, taking advantage of the destructive nature of the algorithm. When you are linking the list, you are also pushing an item into the queue. Each time I try to solve this, I lose nodes (such as each time I link the next node/add to the queue), I require extra storage, or I can't figure out the convoluted method I need to get back to a node that has the pointer I need. Even the link to that original article/post would be useful to me :) Google is giving me no joy. Edit: Jérémie pointed out that there is a fairly simple (and well known answer) if you have a parent pointer. While I now think he is correct about the original solution containing a parent pointer, I really wanted to solve the problem without it :) The refined requirements use this definition for the node: struct tree_node { int value; tree_node* left; tree_node* right; };

• SEO - Does google+other search engines index links within <noscript> tags?

  - by Joe

  I have setup some dropdown menus allowing users to find pages on my website by selecting options across multiple dropdowns: eg. Color of Car, Year This would generate a link like: mysite.xyz/blue/2010/ The only problem is, because this link is dynamically assembled with Javascript, I've also had to assemble each possible combination from the dropdowns into a list like: <noscript> No javascript enabled? Here are all the links: <a href='mysite.xyz/blue/2009/'>mysite.xyz/blue/2009/</a> <a href='mysite.xyz/blue/2010/'>mysite.xyz/blue/2010/</a> <a href='mysite.xyz/red/2009/'>mysite.xyz/red/2009/</a> <a href='mysite.xyz/red/2010/'>mysite.xyz/red/2010/</a> </noscript> My question is, if I put these in a tag like this, will I be penalized or anything by search engines such as Google? I've already been doing so for some navigational stuff which required offsets etc. However, now I would be listing a whole list of links here too. I want to provide them here, moreso so that google can actually index my pages - but for those without javascript, they can still navigate too. Your thoughts? Also.. even though I have some links that appear to have been indexed, I AM NOT 100% SURE, which is why I'm asking :P

• dojo.parser.parse only working first time it's called.

  - by crazymerlin

  I have a page that when a user clicks on a link for some reporting tools, it first asks them to enter some report parameters. I get the parameters dialog as a form using AJAX, based on the id of the link. Each dialog has some dojo controls on it, so I need to parse them when the dialog appears, because it is not originally part of the page. The first dialog when called works fine, but subsequent calls to dialogs fails to parse the dojo controls. Example: showParametersDialog : function(doc) { var content = doc.firstChild.firstChild.data; var container = document.createElement('div'); container.id = 'dialog'; container.innerHTML = content; container.style.background = 'transparent'; container.style.position = 'absolute'; container.style.top = (document.body.clientHeight / 2) - 124 + "px"; container.style.left = (document.body.clientWidth / 2) - 133 + "px"; container.style.display = 'block'; document.body.appendChild(container); // set up date fields var date_from = dojo.byId('date_from'); var date_to = dojo.byId('date_to'); try { date_from.value = dojo.date.locale.format(new Date(), {selector: 'date'}); date_to.value = dojo.date.locale.format(new Date(), {selector: 'date'}); } catch(e) { var now = new Date(); date_from.value = String(now.getMonth() + "/" + now.getDate() + "/" + now.getFullYear()); date_to.value = String(now.getMonth() + "/" + now.getDate() + "/" + now.getFullYear()); } dojo.parser.parse(); } All dialogs have the common date fields. So when I call this dialog the first time, and dojo.parser.parse() is called, it parses the controls on the dialog, but only the first time...after than, no dojo. Any thoughts? Thanks, Paul.

• WIndows Hosted Network

But on executing this command it get the error C:\Users\user>netsh wlan refresh hostednetwork rambo123 Invalid value "rambo123" for command option "data". Usage: refresh hostednetwork [data=]key I have no idea what is wrong with this command.

• Determining the chances of an event occurring when it hasn't occurred yet

  - by sanity

  A user visits my website at time t, and they may or may not click on a particular link I care about, if they do I record the fact that they clicked the link, and also the duration since t that they clicked it, call this d. I need an algorithm that allows me to create a class like this: class ClickProbabilityEstimate { public void reportImpression(long id); public void reportClick(long id); public double estimateClickProbability(long id); } Every impression gets a unique id, and this is used when reporting a click to indicate which impression the click belongs to. I need an algorithm that will return a probability, based on how much time has past since an impression was reported, that the impression will receive a click, based on how long previous clicks required. Clearly one would expect that this probability will decrease over time if there is still no click. If necessary, we can set an upper-bound, beyond which we consider the click probability to be 0 (eg. if its been an hour since the impression occurred, we can be pretty sure there won't be a click). The algorithm should be both space and time efficient, and hopefully make as few assumptions as possible, while being elegant. Ease of implementation would also be nice. Any ideas?

• Combine MD5 hashes of multiple files

  - by user685869

  I have 7 files that I'm generating MD5 hashes for. The hashes are used to ensure that a remote copy of the data store is identical to the local copy. Unfortunately, the link between these two copies of the data is mind numbingly slow. Changes to the data are very rare but I have a requirement that the data be synchronized at all times (or as soon as possible). Rather than passing 7 different MD5 hashes across my (extremely slow) communications link, I'd like to generate the hash for each file and then combine these hashes into a single hash which I can then transfer and then re-calculate/use for comparison on the remote side. If the "combined hash" differs, then I'd start sending the 7 individual hashes to determine exactly which file(s) have been changed. For example, here are the MD5 hashes for the 7 files as of last week: 0709d609d69385255c496436eb50402c 709465a74411bd596595c7b9b158ae6a 4ab657320ef33e3d5eb498e4c13d41b7 3b49c6ab199994fd776bb63761414e72 0fc28c5a010fc3c06c0c930c88e31a15 c4ecd214662cac5aae0e53f6f252bf0e 8b086431e43148a2c2d943ba30d31cc6 I'd like to combine these hashes together such that I get a single unique value (perhaps another MD5 hash?) that I can then send to the remote system. On the remote system, I'd then perform the same calculation to determine if the data as a whole has been changed. If it has, then I'd start sending the individual hashes, etc. The most important factor is that my "combined hash" be short enough so that it uses less bandwidth than just sending all 7 hashes in the first place. I thought of writing the 7 MD5 hashes to a file and then hashing that file but is there a better way?

• netgear GS108TV2 RSTP configuration

  - by jhowland

  I have a large set of GS108TV2 units--my goal is to set up a network which is comprised of several loops for redundancy/fault tolerance. I have a minimal 3 switch loop configured, with RSTP enabled on two ports on each switch. I have my bridge max age set to 6, and my bridge forward delay set to 4, which are the minimum values allowed. Hello time is fixed at 2 seconds. The switches respond to a cable being removed from a socket, but it takes too long. I cannot get the switch to respond to a loss of connection on one of the redundant ports in less than 20 seconds. Is there any way to configure these switches to respond faster than 20 seconds? That is unacceptable for my application. thanks in advance for any help

• How to use Many to Many in Rails?

  - by Newbie

  Hello! In my project, I have users and quests. One User can join multiple quests and one quest can have multiple users. So I created a table called questing, containing the user_id and the quest_id. In my user.rb I did following: require 'digest/sha1' class User < ActiveRecord::Base has_many :questings has_many :quests ,:through =>:questings ... My Quest.rb: class Quest < ActiveRecord::Base has_many :questings has_many :users ,:through =>:questings ... My Questing.rb: class Questing < ActiveRecord::Base belongs_to :quest belongs_to :user end Now I want to create a link or button on my /quests/show.html.erb, calling an action in my controller, which will create the relationship between user and quest. So, in my quest_controller I did: def join_quest @quest = Quest.find(params[:id]) puts '************************' puts 'join quest:' + @quest.id puts '************************' respond_to do |format| format.html { redirect_to(@quest) } format.xml { head :ok } end end and in my show.html.erb I did: <%= link_to 'join this quest!!!', :action => :join_quest %> Now, clicking on this link will cause an error like: Couldn't find Quest with ID=join_quest and the url points to */quests/join_quest* instead of */quests/1/join_quest* Now my questions: Is my quests_controller the right place for my join_quest action, or should I move it to my users_controller? Why do I get this error? How to solve it? What do I have to write in my join_quest action for saving the relationship? On my /users/show.html.erb I want to output all quests the user joined. How to do this? I have to get all this quests from my relationship table, right? How? I hope you can help me! THX!

• How do I set my main monitor to a higher resolution?

  - by Sean

  My laptop monitor's native resolution is 1280x800 and it just isnt big enough for me. I tried to set the resolution higher, but my graphics card only showed options upto 1280x800, and I figured that was the max res my card would allow. I found a monitor out on the street a few days ago and its native resolution is 1024x768. I have been playing around with it a bit. I was looking under the resolutions for it, and I can set it upto 1400x1050, so apparently my card allows for more than 1280x800, so why can't I set my laptop monitor to higher?

  I have some modifications I want to make WITHOUT installing extensions. eg: max width of tab and height of menu, In previous versions you could have it done via: about:config ->browser.tabs.tab.maxWidth Since FF4 it should be done with CSS.

• DotNetOpenAuth getting return_To url as the provider

  - by Jeff

  I have a provider that I'm upgrading from version 2 to version 3. basically a user comes to one of our sites and we say "if you don't have an openID sign up with this one" They click that and are sent to our in house provider what signs them up for an account and has to verify their email address. In the link I send via Email I included the return to url . This way when they click the link to verify their email (sometimes up to a week later) they are sent to our page that knows to send them back to the returnTo to login. I could not find a good way to do this in version 2 so I used a hack. Sadly this hack broke in version 2 so I'm completely stumped as to how to find the login page url that is the return_To Note: I need the full URL not just the domain. old hack: if (ProviderEndpoint.PendingAuthenticationRequest != null) { req = ProviderEndpoint.PendingAuthenticationRequest.ToString(); int startpos = req.LastIndexOf("CheckIdRequest.ReturnTo = '"); startpos += "CheckIdRequest.ReturnTo = '".Length; int endpos = req.LastIndexOf("token=") - startpos-1; if (endpos > 0) { req = req.Substring(startpos, endpos); } else { log.Fatal("Missing token in url" + ProviderEndpoint.PendingAuthenticationRequest.ToString()); return "~/"; } req = req.Replace("&internalLogin=True", ""); req = req.Replace("?internalLogin=True&", "?"); req = req.Replace("?internalLogin=True", ""); }

• How to do this in a smart way

  - by Azzyh

  Hello SO. My websystem im coding with now is integrated from the originally phpBB system. With this i mean when you log on my websystem, you have actually logged into the forum from the login page. Now i came to the "log out" part, and i want to make it smart. Right now its a simply link with logout: <a href="<?php echo BASEDIR; ?>../../ucp.php?mode=logout&sid=<? echo $user->data['session_id']; ?>" style="margin-left: 14px; font-size: 10px;">- Log Out</a> As you see in the link it refers to the forum´s ucp.php?mode=logout, and you need to have the SID variable in it in order to log out right.. anyway.. I want to do this log out part in a smart way, i mean, not so you land on the forum´s "you have now been logged out", i want something maybe like run this page in background when you click, and then it refreshes the current page your on. Or should it be smarter just try to modify the phpbb file ucp.php? I think its hard coded, and not the way I am coding, so thats why i find it abit tricky. Thank you for your answers and examples on how this could be done, in a smart way..

• $_SERVER['HTTP_REFERER'] not working with Header

  - by EmmyS

  I have a site that allows public access to some pages, but requires a login for others. I have a link to the login from all pages, and what I'd like to do after a successful login is send the user back to the page they were on when they clicked the login link. I know the HTTP_REFERER can be spoofed, and sometimes stripped out by certain hosts and proxies, but since it's strictly within my own site, and only a convenience for users, I'm not too worried about it. I am curious about why it isn't working in conjunction with a redirect, though. I've set a visible field to contain the value of the http referer, and it displays correctly. So the page is getting the value of the referrer variable. But when I try this: $home_url = $_SERVER['HTTP_REFERER']; header('Location: ' . $home_url); it doesn't work. This, on the other hand, does: $home_url = 'http://' . $_SERVER['HTTP_HOST'].dirname($_SERVER['PHP_SELF']).'/discussions.php'; header('Location: ' . $home_url); So I know the header location part works. Any idea why it doesn't want to work in conjunction with the http_referer variable? (Also, does it drive anyone else nuts that referer is spelled incorrectly? I keep mistyping it using the OED spelling, silly me...)
