  • Will new Twitter API 1.1 allow hashtag/tweet/trend queries without any authentication, i.e. for a client that does not use an user's account at all?

    - by P5music
    I see that, even not being logged in Twitter with an account, if I google hashtags or twitter accounts, twitter show them. I think it should be also possible to get those tweets programmatically but I do not know it for sure, so I ask for confirmation here, especially for the future with the new Twitter API resctrictions. I mean, will it be possible to get tweets from hashtags or accounts without logging in an user account, and so not wanting to access the user settings, subscriptions, etc (because I do not need it), thus not having to respect any token limit? I found these API 1.1 faqs, have I to be concerned? Will an application have to request user authorization just to make public API calls? When API v1.1 is released, user authorization (and access tokens) are required for all API 1.1 requests. In the weeks following release, some methods will require only application-based authentication for certain "userless" contexts. Will an application have to request user authorization just to make public API calls? When API v1.1 is released, user authorization (and access tokens) are required for all API 1.1 requests. In the weeks following release, some methods will require only application-based authentication for certain "userless" contexts. Will the Search API require authentication? The Search API is now part of the official REST API in version 1.1. In addition to serving results in a format consistent with other Tweet resources, usage will also require authentication.

  • Windows Advanced Firewall certificate based IPSEC

    - by Tim Brigham
    I'm working on migrating from using IPSEC settings stored under the 'IP Security Policies on Active Directory' to using the 'Windows Firewall with Advanced Security' for my 2008+ boxes. I have successfully been able to get this set up using Kerberos authentication, however my openswan implementation on my Linux boxes is using certificates. Whenever I try changing the authentication method to computer certificate (using RSA and my root CA) the connection is bombing out. I've made this change at both a connection request policy and on the IPSEC settings on the root Windows Firewall with Advanced Security node. The windows event log shows the authentication request is taking place but failing negotiating a mode. What am I missing here?

  • TCP > COM1 for receiving messages and displaying on POS display pole

    - by JakeTheSnake
    I currently have a Java Applet running on my web page that communicates to a display pole via COM1. However since the Java update I can no longer run self-signed Java Applets and I figure it would just be easier to send an AJAX request back to the server and have the server send a response to a TCP port on the computer...the computer would need a TCP COM virtual adapter. How do I install a virtual adapter to go from a TCP port to COM1? I've looked into com0com and that is just confusing as hell to me, and I don't see how to connect any ports to COM1. I've tried tcp2com but it doesn't seem to install the service in Windows 7 x64. I've tried com2tcp and the interface seems like it WOULD work (I haven't tested), but I don't want an app running on the desktop...it needs to be a service that runs in the background. So to summarize how it would work: Web page on comp1 sends AJAX request to server Server sends text response to comp1 on port 999 comp1 has virtual COM port listening on port 999, sends data to COM1 pole displays data

  • Why is rsync.exe [cwRsync] trying to open a port when in client mode?

    - by hemancuso
    I'm trying to use a cygwin compiled version of rsync [the cwrsync package] on Windows and in seemingly whatever configuration I test in there is a request to the user presented by Windows Firewall to allow inbound traffic. If you deny this request, everything works fine - as expected. I'm doing a vanilla push rsync.exe localpath user@remotepath:/absolutepath and it works just fine. I've also attempted this command having deleted ssh from the path and using rsync on local paths - still a firewall prompt. Why is this listen() happening and is there a way I can force the client to not attempt to listen without recompiling and maintaing a patch?

  • Tomcat access logs - are failed requests included?

    - by Maxim Eliseev
    We have a RESTful web service (Java, hosted in Tomcat on Ubuntu on Amazon EC2). From time to time it fails (not every week). When it fails, Java CPU consumption goes to 100% and it takes all available memory. It does not finish by itself. I have to restart the server. There is nothing suspicious in Tomcat access logs. I guess one of our users could submit a very "heavy" request which brought the server down. Is it possible this request is not in Tomcat logs since it never finished?

  • Spreading incoming batched data into a real-time stream

    - by pr1001
    I would like to display some events in 'real-time'. However, I must fetch the data from another source. I can request the last X minutes, though the source is updated approximately every 5 minutes. This means that there will be a delay between the most recent data retrieved and the point in time that I make the request. Second, because I will be receiving a batch of data, I don't want to just fire out all the events down a socket once my fetcher has retrieved it: I would like to spread out the events so that they are both accurately spaced amongst each other and in sync with their original occurrences (e.g. an event is always displayed 6 minutes after it actually happened). My thought is to fetch the data every 5 minutes from the source, knowing that I won't get the very latest data. The original data would be then queued to be sent down the socket 7.5 minutes from its original timestamp – that is, at least ~2.5 minutes from when its batch was fetched and at most 7.5 minutes since then. My question is this: is this the best way to approach the problem? Does this problem have any standard approaches or associated literature related to implementation best-practices and edge cases? I am a bit worried that the frequency of my fetches and the frequency in which the source is updated will get out of sync, leading to points where no data will be retrieved from the source. However, since my socket delay is greater than my fetch frequency, the subsequent fetch should retrieve newer data before the socket queue is empty. Is that correct? Am I missing something? Thanks!

  • HTTP Caching Server that supports POST

    - by Jeroen
    I am hosting a REST service which is sending appropriate cache-control headers. I use Varnish as a caching server in front of my webserver. However, a limitation of varnish is that it doesn't support caching HTTP POST and HTTP PUT. Is there any alternate caching server that will be able to cache these requests? I understand that caching POST is a bit tricky because you cannot just cache based on the url as a key like for GET; it needs to actually inspect the request body. In case of multipart/form-data requests, there should probably be a limit on the size of the request body for it to be cached (so that big file uploads, etc won't be cached). Nevertheless I really want to be able to cache short HTTP POST, or at least the application/x-www-form-urlencoded ones.

  • Files slow to save sometimes after Ubuntu upgrade

    - by Matchu
    I haven't quite been able to track down why this happens sometimes in Ubuntu 10.04 and not other times. I'll go into gedit or OpenOffice.org and try to save files, and, during some sessions, it will take up to 10 seconds to save the file, sometimes causing the program to become unresponsive. But during these same sessions, the files sometimes save instantly. This didn't start happening until after the 10.04 (Lucid) upgrade. I suspect that something is reading all the changes I make, or that there's some other big file action going on, or something like that. I disabled Tracker a while back, before the upgrade, and don't see it under the settings - could it be back under a different name under Lucid? You probably don't already know the answer, but how can I go about finding the cause of this problem?

  • Log incoming requests on Ubuntu (ports 80, 443)

    - by Maxim Eliseev
    We have Tomcat running on Ubuntu server. It runs a web service, open to the internet. Sometimes it has a sudden spike of traffic and goes down. There is nothing unusual in Tomcat access logs. I guess it is because some of the requests are so 'heavy' that they never finish and hence are not recorded to Tomcat access logs. Is there a way to configure Ubuntu to log incoming requests in the following format (below)? Date, Time, URL (with query string params), IP address (of client) There should be one line per request. Each request should be logged before it is executed. Only incoming requests to ports 80 and 443 should be logged.

  • Passenger, Apache and avoiding page caching

    - by user38382
    I'm hosting a rack application with passenger and apache. The application is setup to cache the content of each request to the public directory after each request. This allows apache to serve the content directly as a static page for future requests. I would like to tell Apache, presumably through some rewrite rules that any requests with query parameters should not be cached, but instead passed down to the rack application. With a mongrel setup I would just redirect it to the balancer if it meets my rewrite conditions. How do you do the same with passenger?

  • Sneak Preview - New CodePlex UI

    We have been busy the last several months working to improve the overall experience for the CodePlex community. We have been working through some of the top requested items, such as our big announcement last week enabling Git. Something that is not explicitly on the feature request list are requests to update the web site look and user experience.  As Brian Harry mentioned, the Future of CodePlex is Bright, so it is time to start brightening up the place. Goals As with any sizeable change you need to decide the scope of changes you want to tackle. We decided that we would optimize on incremental improvements verses taking months to get a completely new experience released. Our goals with this user experience work is to refresh the look and feel of the site, introduce new visual elements and set up the site for future structural changes. So this is not the end, just the beginning. Early Views I want to set a few expectations first, these screen shots are not final, and we are still working through the content and final element placement. Feedback is always welcome, just take that in mind as you review the images. New CodePlex Home The navigation changed a good bit on the home page and we have moved the search to a more consistent location across the site.   User Profile Users Home Page The goal was to make it easier to find and take action on common tasks such as creating projects. Project Home Issue Tracker   This should give you a taste of where we are going with the new user experience.     As always we love the feedback, either comment below, find us on Twitter @codeplex or @mgroves84, or create or vote up suggestions.

  • Which built-in account is used for Anonymous Authentication in IIS 7?

    - by smwikipedia
    We know that Microsoft IIS 7.0 offer a slew of authentication methods such as Anonymous Authentication, Form Based Authentication, Digest Authentication, etc. I read from Professional IIS 7 published by Wrox that: When we use Anonymous Authentication, the end-user does not supply credentials, effectively mak- ing an anonymous request. IIS 7.0 impersonates a fixed user account when attempting to process the request (for example, to read the file off the hard disk). So, what is the fixed user account impersonated by IIS? Where can I see it? If I don't know what this account is, how could I assign proper permissions for the clients who are authenticated as anonymous users? Thanks.

  • Why is domU faster than dom0 on IO?

    - by Paco
    I have installed debian 7 on a physical machine. This is the configuration of the machine: 3 hard drives using RAID 5 Strip element size: 1M Read policy: Adaptive read ahead Write policy: Write Through /boot 200 MB ext2 / 15 GB ext3 SWAP 10GB LVM rest (~500GB) emphasized text I installed postgresql, created a big database (over 1GB). I have an SQL request that takes a lot of time to run (a SELECT statement, so it only reads data from the database). This request takes approximately 5.5 seconds to run. Then, I installed XEN, created a domU, with another debian distro. On this OS, I also installed postgresql, with the same database. The same SQL request takes only 2.5 seconds to run. I checked the kernel on both dom0 and domU. uname-a returns "Linux debian 3.2.0-4-amd64 #1 SMP Debian 3.2.41-2+deb7u2 x86_64 GNU/Linux" on both systems. I checked the kernel parameters, which are approximately the same. For those that are relevant, I changed their values to make them match on both systems using sysctl. I saw no changes (the requests still take the same amount of time). After this, I checked the file systems. I used ext3 on domU. Still no changes. I installed hdparm, and ran hdparm -Tt on both systems, on all my partitions on both systems, and I get similar results. Now, I am stuck, I don't know what is different, and what could be the cause of such a big difference. Additional Info: Debian runs on a Dell server PowerEdge 2950 postgresql: 9.1.9 (both dom0 and domU) xen-linux-system: 3.2.0 xen-hypervisor: 4.1 Thanks EDIT: As Krzysztof Ksiezyk suggested, it might be due to some file caching system. I ran the dd command to test both the read and write speed. Here is domU: root@test1:~# dd if=/dev/zero of=/root/dd count=5MB bs=1MB ^C2020+0 records in 2020+0 records out 2020000000 bytes (2.0 GB) copied, 18.8289 s, 107 MB/s root@test1:~# dd if=/root/dd of=/dev/null count=5MB bs=1MB 2020+0 records in 2020+0 records out 2020000000 bytes (2.0 GB) copied, 15.0549 s, 134 MB/s And here is dom0: root@debian:~# dd if=/dev/zero of=/root/dd count=5MB bs=1MB ^C1693+0 records in 1693+0 records out 1693000000 bytes (1.7 GB) copied, 8.87281 s, 191 MB/s root@debian:~# dd if=/root/dd of=/dev/null count=5MB bs=1MB 1693+0 records in 1693+0 records out 1693000000 bytes (1.7 GB) copied, 0.501509 s, 3.4 GB/s What can be the cause of this caching system? And how can we "fix" it? Can we apply it to dom0? EDIT 2: I switched my virtual disk type. To do so I followed this article. I did a dd if=/dev/vg0/test1-disk of=/mnt/test1-disk.img bs=16M Then in /etc/xen/test1.cfg, I changed the disk parameter to use file: instead of phy: it should have removed the file caching, but I still get the same numbers (domU being much faster for Postgres)

  • Apache2 + FCGI + PHP5 not creating sockets / pools

    - by CodyRo
    I have a pretty vanilla setup with Apache2, FastCGI setup as DSO and serving PHP through an external CGI script that sets the max children / serves the request to PHP. The issue is FastCGI doesn't appear to be creating the PHP sockets / pooling them so each request calls the php-cgi binary, then dies off .. effectively making the reason I want to use FastCGI moot. The only configuration directives I have are: AddHandler php5-fastcgi .php Action php5-fastcgi /cgi-bin/fcgi.cgi FastCgiIpcDir /usr/local/apache2/fastcgi The dyanmic/ directory is getting created as anticipated, but there are no sockets in there. Permissions are indeed correct. Any help would be greatly appreciated, thanks!

  • Generate a Word document from list data

    - by PeterBrunone
    This came up on a discussion list lately, so I threw together some code to meet the need.  In short, a colleague needed to take the results of an InfoPath form survey and give them to the user in Word format.  The form data was already in a list item, so it was a simple matter of using the SharePoint API to get the list item, formatting the data appropriately, and using response headers to make the client machine treat the response as MS Word content.  The following rudimentary code can be run in an ASPX (or an assembly) in the 12 hive.  When you link to the page, send the list name and item ID in the querystring and use them to grab the appropriate data. // Clear the current response headers and set them up to look like a word doc.HttpContext.Current.Response.Clear();HttpContext.Current.Response.Charset ="";HttpContext.Current.Response.ContentType ="application/msword";string strFileName = "ThatWordFileYouWanted"+ ".doc";HttpContext.Current.Response.AddHeader("Content-Disposition", "inline;filename=" + strFileName);// Using the current site, get the List by name and then the Item by ID (from the URL).string myListName = HttpContext.Current.Request.Querystring["listName"];int myID = Convert.ToInt32(HttpContext.Current.Request.Querystring["itemID"]);SPSite oSite = SPContext.Current.Site;SPWeb oWeb = oSite.OpenWeb();SPList oList = oWeb.Lists["MyListName"];SPListItem oListItem = oList.Items.GetItemById(myID);// Build a string with the data -- format it with HTML if you like. StringBuilder strHTMLContent = newStringBuilder();// *// Here's where you pull individual fields out of the list item.// *// Once everything is ready, spit it out to the client machine.HttpContext.Current.Response.Write(strHTMLContent);HttpContext.Current.Response.End();HttpContext.Current.Response.Flush();

  • uWSGI and python virtual env

    - by user27512
    I'm trying to use uWSGI with a virtual env in order to use the Trac bug tracker on it. I've installed system-wide uwsgi via pip. Next, I've installed trac in a virtualenv $ virtualenv venv $ . venv/bin/activate $ pip install trac I've then written a simple uWSGI configuration script: [uwsgi] master = true processes = 1 socket = localhost:3032 home = /srv/http/trac/venv/ no-site = true gid = www-data uid = www-data env = TRAC_ENV=/srv/http/trac/projects/my_project module = trac.web.main:dispatch_request But when I try to launch it, it fails: $ uwsgi --http :8000 --ini /etc/uwsgi/vassals-available/my_project.ini --gid www-data --uid www-data ... Set PythonHome to /srv/http/trac/venv/ ... *** Operational MODE: single process *** ImportError: No module named trac.web.main unable to load app 0 (mountpoint='') (callable not found or import error) I think uWSGI isn't using the virtual env. When inside the virtual env, I can import trac.web.main without having an ImportError. How can I do that ? Thanks

  • Apache Web Server character encoding

    - by OBY
    I've recently transferred my webapp from my localhost (LH) to a VPS, and have had hebrew chars-encoding probs since. Whenever I send a request with a heb-char it results in "?????" saved to the DB. My LH config was tomcat6, MySQL, and centOS 6.2, opened to the web. In the VPS env I'm behind an Apache Web Server, and the rest is quite the same (though I haven't done anything to its installation). Please note I already have had this problem before, on my LH when the request was sent from IE/chrome (not FF!). The solution was to apply a filter on the the context and change the char-type to UTF-8. My webapp content char-encode is utf-8, MySql server set to utf8 using charset utf8;, and my centOS set to iw_IL.UTF8 using export LANG=iw_IL.UTF8. When I use locale the bash output seems to be set correctly. Any suggestions?

  • Hyperic HQ metrics not working

    - by Robin Weston
    I am having a problem with Hyperic HQ. Several metrics, some in IIS 6.x (Request Execution Time, Request Wait Time) and some in .NET 2.0 (Bytes in all Heaps, Exceptions Thrown per Minute), always show 0. If I view perfmon on the server itself I can see that the counters have values greater than zero. There are some metrics that work fine, such as Total Get Requests per Minute and the other IIS defaults. I have looked in the server logs but nothing obvious shows up. Please advise. Am happy to find more information if required.

  • xinet vs iptables for port forwarding performance

    - by jamie.mccrindle
    I have a requirement to run a Java based web server on port 80. The options are: Web proxy (apache, nginx etc.) xinet iptables setuid The baseline would be running the app using setuid but I'd prefer not to for security reasons. Apache is too slow and nginx doesn't support keep-alives so new connections are made for every proxied request. xinet is easy to set up but creates a new process for every request which I've seen cause problems in a high performance environment. The last option is port forwarding with iptables but I have no experience of how fast it is. Of course, the ideal solution would be to do this on a dedicated hardware firewall / load balancer but that's not an option at present.

  • Is sending data to a server via a script tag an outdated paradigm?

    - by KingOfHypocrites
    I inherited some old javascript code for a website tracker that submits data to the server using a script url: var src = "http://domain.zzz/log/method?value1=x&value2=x" var e = document.createElement('script'); e.src = src; I guess the idea was that cross domain requests didn't haven't to be enabled perhaps. Also it was written back in 2005. I'm not sure how well XmlHttpRequests were supported at the time. Anyone could stick this on their website and send data to our server for logging and it ideally would work in most any browser with javascript. The main limitation is all the server can do is send back javascript code and each request has to wait for a response from the server (in the form of a generic acknowledgement javascript method call) to know it was received, then it sends the next. I can't find anyone doing this online or any metrics as to whether this faster or more secure than XmlHttpRequests. I don't know if this is just an old way of doing things or it's still the best way to send data to the server when you are mostly trying to send data one way and you need the best performance possible. So in summary is sending data via a script tag an outdated paradigm? Should I abandon in favor of using XmlHttpRequsts?

  • Is it possible to use bittorrent for a fileserver

    - by sris
    I would like to set up a file server that is searchable, preferable via the web. I'm wondering if it would be possible to achieve this using the bittorrent protocol and have a single client sharing every single torrent on the server. I guess I could use some available tracker solution for the webinterface or write one myself. My concerns are the if there are any limits to the number of torrents a single client can share since this may potentially be 10k torrents. The number of downloading clients is very small, only myself and my relatives. The idea is to have a single place to host everything from vacation photos to musical creations. Is there any other options for this kind of file server. It should also be easy to upload files to the server.

  • Does Apache 2.2 (windows) have any default bandwidth limit?

    - by igino manfre'
    I'm running Apache on a server in cloud (Windows server 2008 R2 on VMware, 1 Gbps of BW, http://95.110.164.61 ). I'm streaming many live DVB MPEG Transport Stream, precompressed in loop, (not flash) generated by VLC on port 640xx and then reverse proxied by Apache on port 80. The server's firewall is open for VLC and Apache on all ports. Above 1.5 Mbps the reproduction is affected by continous stop & go. Please note that if you request a stream generated by VLC directly at http://95.110.164.61:64087/mpg2_6.4 you see a correct stream, while if you request http://95.110.164.61/mpg2_6.4 you do not. I know that Flash streaming Server uses Apache to stream on port 80 (and it works). I'm not an expert with Apache, can anyone tell me if any "special" module is required to increase the bandwidth?

  • Project frozen - what should I leave to the people after me?

    - by Maistora
    So the project I've been working on is now going to be frozen indefinitely. It is possible that if and when the project unfreezes again, it won't be assigned to me or anybody from the current team. Actually, we inherited the project after it had been frozen before, but there was nothing left by the prior team to help us understand even the basic needs of the project, so we wasted a lot of time getting to know the project well. My question is what do you think we should do to help the people after us to best understand the needs of the project, what we have done, why we've done it, etc. I am open to other ideas of why should we leave some tracks to the others that will work on this project also. Some steps we already have taken: technical documentation (not full but at least there is some); source-control system history; estimations on which parts of the project need improvement and why we think so; bunch of unit tests. issue tracker with all the tickets we've done (EDIT) What do you think of what we've already prepared and what else can we do?
