• How can you stream results as json string downloads?

  - by midas06

  I'm interested in presenting results faster in my mobile app. Is it possible to stream results out as the string downloads? I'm thinking about implementing an IObservable to push out the results as they are downloaded, but I don't know what algorithm to use to properly piece together the data which could be incomplete at any given point. Hope that was clear enough. CLARIFICATION: Guess it wasn't clear enough. My issue is the string downloaded is quite long. It can often take 15-20 seconds or more to download. I want to reflect changes faster to my user, so I would like to use reactive extensions to pump out entities as soon as a complete one is received. My issue is I dont know how to build the parser that can pick out complete entities from an incomplete response string.

• Which browser is the most secure? (research and practically based)

  - by wag2639

  I was wondering which browser is the most secure today, Firefox, Internet Explorer, Chrome, or Safari on a Windows machine with the user running as a Power User/Administrator account. This is not a question about which browser is the best because its the most usable, but more of a question if asked for security, which browser is the most secure given an everyday user's experience (JavaScript, Flash, Ads, etc). Also, would the choice for most secure change if the user was running as a restricted user? To clarify, I'm looking for an answer that's based in research on potential and common exploits and how long it takes for critical problems to be patched.

• Where is this error message coming from?

  - by jordanpg

  Recently switched to a new ISP after a move, running Chrome under OSX 10.7. I see the following error when visiting various sites -- no particular pattern -- from time to time. This is the entire message. It is the only thing that appears in my web browser. The problem fixes itself in a few minutes. Probably a lookup error of some sort, but I don't recognize it. What piece of software is serving this message? What is happening? What is this Reference # referencing? Invalid URL The requested URL "/articles/6517181", is invalid. Reference #9.6f200f6c.235618518a.b7e910cf

• Explicitly persist states in Workflow 4.0 rather than everything.

  - by jlafay

  I have ran into an issue with my SQL instance store attached to a WorkflowApplication that is running. When I exit my application I'm calling an Unload() on the WF app to persist it. I didn't think about it during design time, but it does makes sense, it's persisting an arg that was passed in to the WorkflowApplication constructor when instanced. When the application runs, everything in the workflow works as expected. When I call Unload() I get an unhandled exception that states that the arg is not serializable and needs [DataContractAttribute]. What's passed into the workflow is my applications custom logger object that I wrote so that the WF can log to disk in a uniform way that I prefer. How do I prevent the workflow app from persisting this one argument and persist everything else? I'm sure something can be done with extensions but I'm having a hard time finding info on them or finding persistence examples for my scenario.

• SSL encryption standards by browser

  - by hfidgen

  Hiya, Does anyone have a table of the default levels of encryption which the various browsers out there support? For instance I know that IE5 and lower struggle even to cope with 40 bit encryption but the latest browsers easily do 256 and beyond. The reason I ask is that I'm looking to get a wildcard certificate for my domain and the price difference is huge between a server gated certificate (where it enforces a minimum of 128bit) and a non-gated certificate (where the browser sets the encryption level). Obviously I like the idea of paying £300 less for the non-gated certificate, but only if I can be sure that the majority of my users (FF3 / Opera / Chrome / IE7+) are going to get good encryption.

• Certain websites do not open. Instead a 1*1 image gets displayed

  - by Ranjith - SR2GF

  When I try to visit certain websites like www.bidvertiser.com, www.buysellads.com, a white page shows up, the title bar displays the site name followed by (1x1) in brackets. When I right click, 'View Source' option appears disabled. The Save As.. option shows the file type to be gif. However, when I preview the site in Google search results ( by moving the mouse over ) the screenshot of the site displays well. This happens on all the three browsers on my computer: Chrome, Firefox and IE. What is the problem and how can it be resolved? EDIT: At some point of time, they probably worked on my computer! I think it is a more general problem. The same happens when I click on certain links in Google search results.

• Why can't there be an "ultimate" programming language? [closed]

  - by sub

  There is an uncountable sum of programming languages out there. They obviously all have their pro's and con's - but why can't there be one to "beat them all"? The main part of a programming language is it's syntax and what's possible with it. The rest are usually only a bunch of libraries, frameworks and extensions wrapped around it. So couldn't you combine all the great aspects and experiences gained from the thousands of programming languages out there to build one with a syntax that fits every task? Wouldn't it be better having only one programming language? I see only problems with the current amount of the ones in use. Why can't there be a perfect language when thinking of syntax, constructs and typing?

• Having an issue with Java/ minecraft (Windows 7 64bit)

  - by MetroGnome

  I have had issues with java on my computer for a while. First of all, java has never worked on Google Chrome or Firefox, Only IE. Whenever I need to use Java, I use IE. Now, I just tried to play minecraft the other week and I receive the error "fatal error (1)" and get a black screen (this is on the online free version). Now, I searched for java and found that I have Java 32 bit. I cannot uninstall it on Revo uninstaller or Windows uninstaller. What should I do?

• Haskell: foldl' accumulator parameter

  - by Clinton

  I've been asking a few questions about strictness, but I think I've missed the mark before. Hopefully this is more precise. Lets say we have: n = 1000000 f z = foldl' (\(x1, x2) y -> (x1 + y, y - x2)) z [1..n] Without changing f, what should I set z = ... So that f z does not overflow the stack? (i.e. runs in constant space regardless of the size of n) Its okay if the answer requires GHC extensions. My first thought is to define: g (a1, a2) = (!a1, !a2) and then z = g (0, 0) But I don't think g is valid Haskell.

• In what platforms/browsers does Adobe Flash come preinstalled?

  - by Michael Haren

  In what platforms/browsers does Adobe Flash come preinstalled? I'm pretty sure neither FireFox nor Safari include it on any platform but Chrome on Windows does (not sure about Mac or Linux). What about IE on a completely vanilla Win XP system? Or Win 7? Maybe mfgs like Dell add it if MS doesn't? Perhaps we can find (or build) a comprehensive list. Considering that Flash is a significant piece of the web platform, I hope I've asked this on the right place.

• Allow access only to one website

  - by Alex

  Hey. I'd like to allow access on a computer connected directly to the internet to one website ONLY. The solution of IE's "Content advisor" or firefox's "FoxFilter" isn't good enough because it actually downloads the data and just don't display it. I want to block the traffic before the requests are sent. How is it possible? Thanks. Edit: OS is windows xp. The browser can be firefox, iexplorer, chrome... It doesn't matter. The computer is connected directly to the modem.

• How do you stop windows 7 from auto streaming mp3's online?

  - by angryuser

  Be it IE, Firefox or Chrome whenever I try to download a media file windows 7 starts streaming it in the browser instead of giving me options about what I want to do with the file i'm trying to download. I know the problem is with the OS and not the browser because I can download the file just fine off the website when I use Ubuntu. I get the feeling somewhere a setting is saying "open all mp3's in browser" but I dont know where to find or change it. Can anyone help? Edit: If I click on the FLAC version of the audio file, windows 7 automatically downloads it. If I click on the MP3 version, it automatically streams it to the browser.

• Is it possible with Google searches to ban any and all results from a domain? [closed]

  - by Stu Thompson

  Is it possible to configure Google somehow to permanently ban search results from domains that I know 100% are never, ever going to make me happy? Something cookie/session based maybe? E.g. I want to ban (permanently, forever and always) results from experts-exchange.com. Every time I click results that take me to their page I just want to scream. Update! Google has released a Chrome Extension to allow users to block individual site from Google search results! Personal Blocklist (by Google). (Since this question has been closed, I cannot answer it.)

• Why is numpy c extension slow?

  - by Bitwise

  I am working on large numpy arrays, and some native numpy operations are too slow for my needs (for example simple operations such as "bitwise" A&B). I started looking into writing C extensions to try and improve performance. As a test case, I tried the example given here, implementing a simple trace calculation. I was able to get it to work, but was surprised by the performance: for a (1000,1000) numpy array, numpy.trace() was about 1000 times faster than the C extension! This happens whether I run it once or many times. Is this expected? Is the C extension overhead that bad? Any ideas how to speed things up?

• Cannot open some websites

  - by Jayashree

  Hi all, I have a very specific problem. We have a wifi router at home which supports three laptops and a desktop. For the past month or so, I've been unable to open a number of websites on our HP desktop, Dell laptop and my Macbook. These include everything connected with http://wordpress.org and several others. The page simply refuses to load. I can't access some other websites as well. I've tried everything. We've rebooted the router, deleted all the cookies/download history, but nothing works. I've tried accessing these websites on IE, Chrome, Firefox and Safari. Strangely, when friends use their laptops on the same wifi connection, the websites open just fine. What do I do? I'm getting desperate here. Jayashree

• Can you use POST to run a query in Solr (/select)

  - by RyanFetz

  I have queries that I am running against out solr index that sometimes have very long query parameters, I get errors when i run these queries, which i assume are do to the limit of a GET query parameters. Here is the method I use to query (JSON), this is to show I am using the Http Extensions (the client i use is a thin wrapper for HttpClient) not an end to end solution. 90% of the queries run fine, it is just when the params are large i get the 500 error from solr. I have read somewhere you can use POSt's when doing the select command but have not found examples of how to do it. Any help would be fantastic! public string GetJson(HttpQueryString qs) { using (var client = new DAC.US.Web.XmlHttpServiceClient(this.Uri)) { client.Client.DefaultHeaders.Authorization = new Microsoft.Http.Headers.Credential("Basic", DAC.US.Encryption.Hash.WebServiceCredintials); qs.Add("wt", "json"); if (!String.IsNullOrEmpty(this.Version)) qs.Add("version", this.Version); using (var response = client.Get(new Uri(@"select/", UriKind.Relative), qs)) { return response.Content.ReadAsString(); } } }

• Why are my favorite websites becoming slower, over months?

  - by Wolfpack'08

  I spend a lot of my time at sites for watching online videos: youtube, gorillavid, thedailyshow.com etc. I used to watch the videos in full screen mode, and then that became very laggy. So, I started watching them with full-browser zooming. Then that became laggy. Recently, I've had to actually zoom out; otherwise, the video will lag so much that my PC locks. Could this be a symptom of my processor, RAM, or motherboard going bad? Has it, perhaps, anything to do with softwares like Chrome or the playeres the sites are using being updated?

• Windows XP - Website unaccessible on single pc in LAN

  - by DorentuZ

  For serveral days now, a website isn't accessible on a single pc in the LAN. On the other pc's, it works just fine. And it's just a single website that's not accessible as far as I know of. The website generates a timeout on every single web browser I've tried (IE8, Firefox and Chrome). However, traceroute, nmap and telnet all work just fine. I've even tried multiple user accounts and safe mode, but that didn't work either. As a side note: using a linux live cd did work and I could access the website without any problems. The hosts file is the windows default, the ip- and dns settings on the network adapter normal as well. No strange processes are running and no viruses found. According to tcpview and netstat there are connections to the domain, but every request in the browser results in a timeout.. Any idea what's happening?

• Why my Firefox displays XML files as blank pages?

  - by n1313

  Every time I open an XML file, all I get is blank page instead of tag tree. The file itself is correct and loads okay, I can see it via View Source or in the Firebug. I've tried turning off all my addons, but the problem was not solved. All other browsers (Chrome, Opera) render the same file as an XML tree. I'm guessing that I've messed up my configuration somehow and Firefox now tries to render XML files as HTML ones. I've tried googling, but with no success. Help, please?

• Change save to file name but from the client

  - by Rhythmic Algorithm

  This question asks about file name the servers sends and the fix was quite simply a content-disposition header in the http response. What I interested in is does anyone know of any way to do this from the client side if the file name is already known? Is there any special javascript to do this for example? A site I have to use but not mine has a FileDownload.aspx but it doesn't send the content-disposition header. I know the filename and would like to be able to create a firefox extensions to use for the poorly coded web site. Thanks

• Through Java, make a call to Javascript functions on networked device?

  - by stjowa

  I am doing device monitoring on a networked system. I need to know how to make Javascript calls on that device via its IP address to get certain status information (this device's status is only available through Javascript APIs, not SNMP, etc). I am working in Java. ADDED: The specific device is an Amino set-top-box. It has what it calls JMACX: JavaScript Media Access Control Extensions API specification. It allows you within an HTML document to use that API to get MUCH information about the device (cpu usage, channel info, remote-control options, etc.). I need to get this information within a Java program for specific monitoring purposes. Perhaps possible with HTTP requests? Any input would be greatly appreciated. Thanks, Steve
