  • What to do with input during movement?

    - by user1895420
    In a concept I'm working on, the player can move from one position in a grid to the next. Once movement starts it can't be changed and takes a predetermined amount of time to finish (about a quarter of a second). Even though their movement can't be altered, the player can still press keys (perhaps in anticipation of their next move). What do I do with this input? Possibilities i've thought of: Ignore all input during movement. Log all input and loop through them one by one once movement finishes. Log the first or last input and move when possible. I'm not really sure which is the most appropriate or most natural. Hence my question: What do I do with player-input during movement?

  • Populate a WCF syndication podcast using MP3 ID3 metadata tags

    - by brian_ritchie
    In the last post, I showed how to create a podcast using WCF syndication.  A podcast is an RSS feed containing a list of audio files to which users can subscribe.  The podcast not only contains links to the audio files, but also metadata about each episode.  A cool approach to building the feed is reading this metadata from the ID3 tags on the MP3 files used for the podcast. One library to do this is TagLib-Sharp.  Here is some sample code: .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: Consolas, "Courier New", Courier, Monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } 1: var taggedFile = TagLib.File.Create(f); 2: var fileInfo = new FileInfo(f); 3: var item = new iTunesPodcastItem() 4: { 5: title = taggedFile.Tag.Title, 6: size = fileInfo.Length, 7: url = feed.baseUrl + fileInfo.Name, 8: duration = taggedFile.Properties.Duration, 9: mediaType = feed.mediaType, 10: summary = taggedFile.Tag.Comment, 11: subTitle = taggedFile.Tag.FirstAlbumArtist, 12: id = fileInfo.Name 13: }; 14: if (!string.IsNullOrEmpty(taggedFile.Tag.Album)) 15: item.publishedDate = DateTimeOffset.Parse(taggedFile.Tag.Album); This reads the ID3 tags into an object for later use in creating the syndication feed.  When the MP3 is created, these tags are set...or they can be set after the fact using the Properties dialog in Windows Explorer.  The only "hack" is that there isn't an easily accessible tag for "subtitle" or "published date" so I used other tags in this example. Feel free to change this to meet your purposes.  You could remove the subtitle & use the file modified data for example. That takes care of the episodes, for the feed level settings we'll load those from an XML file: .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: Consolas, "Courier New", Courier, Monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } 1: <?xml version="1.0" encoding="utf-8" ?> 2: <iTunesPodcastFeed 3: baseUrl ="" 4: title="" 5: subTitle="" 6: description="" 7: copyright="" 8: category="" 9: ownerName="" 10: ownerEmail="" 11: mediaType="audio/mp3" 12: mediaFiles="*.mp3" 13: imageUrl="" 14: link="" 15: /> Here is the full code put together. Read the feed XML file and deserialize it into an iTunesPodcastFeed classLoop over the files in a directory reading the ID3 tags from the audio files .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: Consolas, "Courier New", Courier, Monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } 1: public static iTunesPodcastFeed CreateFeedFromFiles(string podcastDirectory, string podcastFeedFile) 2: { 3: XmlSerializer serializer = new XmlSerializer(typeof(iTunesPodcastFeed)); 4: iTunesPodcastFeed feed; 5: using (var fs = File.OpenRead(Path.Combine(podcastDirectory, podcastFeedFile))) 6: { 7: feed = (iTunesPodcastFeed)serializer.Deserialize(fs); 8: } 9: foreach (var f in Directory.GetFiles(podcastDirectory, feed.mediaFiles)) 10: { 11: try 12: { 13: var taggedFile = TagLib.File.Create(f); 14: var fileInfo = new FileInfo(f); 15: var item = new iTunesPodcastItem() 16: { 17: title = taggedFile.Tag.Title, 18: size = fileInfo.Length, 19: url = feed.baseUrl + fileInfo.Name, 20: duration = taggedFile.Properties.Duration, 21: mediaType = feed.mediaType, 22: summary = taggedFile.Tag.Comment, 23: subTitle = taggedFile.Tag.FirstAlbumArtist, 24: id = fileInfo.Name 25: }; 26: if (!string.IsNullOrEmpty(taggedFile.Tag.Album)) 27: item.publishedDate = DateTimeOffset.Parse(taggedFile.Tag.Album); 28: feed.Items.Add(item); 29: } 30: catch 31: { 32: // ignore files that can't be accessed successfully 33: } 34: } 35: return feed; 36: } Usually putting a "try...catch" like this is bad, but in this case I'm just skipping over files that are locked while they are being uploaded to the web site.Here is the code from the last couple of posts.

  • How do I configure nVidia drivers on a Portable Ubuntu setup?

    - by Nicholas Flynt
    I've been pulling my hair out over this one for a couple of days now, google is no help. I've created a wonderful (until this issue) portable copy of Ubuntu linux that will boot on mostly anything by using a USB enclosure for my laptop's 80GB SATA drive. So far so good, it boots and runs on everything, and on non-nVidia card setups was even detecting the drivers, or letting me install the required drivers for hardware acceleration and compiz. Because you know, the wobble windows are the most awesome thing ever. Anyway, my desktop machine had an nVidia card, so I'm thinking, sure, I'll just install the nVidia drivers like before and everything will work happily. Not so-- now the desktop and any other nVidia cards work great, but it seems to have completely disabled any other graphics cards. When the kernel module detects that an nVidia card isn't present, it shoots up this nasty little dialog box giving me the option to boot into "low graphics" mode, which doesn't even allow me to use the correct screen resolution, much less see the installed graphics card and try to configure a driver for it. Is there any way to configure Ubuntu (with the dreaded nVidia kernel module) so that it can use nVidia's drivers when an nVidia card is present, and default to the normal (not low-graphics) setup in other cases, so that it has a fair chance of using what's actually present? I'm not afraid to much with config files, I just don't know the underlying system well enough to feel comfortable diving in without a push in the right direction. Thanks guys!

  • Morgan Stanley chooses Solaris 11 to run cloud file services

    - by Frederic Pariente
    At the EAKC2012 Conference last week in Edinburg, Robert Milkowski, Unix engineer at Morgan Stanley, presented on deploying OpenAFS on Solaris 11. It makes a great proofpoint on how ZFS and DTrace gives a definite advantage to Solaris over Linux to run AFS distributed file system services, the "cloud file system" as it calls it in his blog. Mike used ZFS to achieve a 2-3x compression ratio on data and greatly lower the TCA and TCO of the storage subsystem, and DTrace to root-cause scalability bottlenecks and improve performance. As future ideas, Mike is looking at leveraging more Solaris features like Zones, ZFS Dedup, SSD for ZFS, etc.

  • Vim key mappings / plugin XCode?

    - by Daniel Upton
    I'm a developer who mostly does web stuff in ruby and C#.. I'd like to start tinkering with iOS and Mac development, Over the last few month i've been trying to get fluent in one set of key bindings (vi / vim because it just feels right).. I have the awesome ViEmu installed for visual studio on windows which gives me a ton of the vim awesomeness side by side with visual studio power toys.. Is there anything like this for xcode? I know i could set up MacVim as the default editor but i'm not too interested in this as it means losing all of xcode's cocoa awareness.. The other option of course would be to go for the lowest common denominator and switch to emacs (as the mac keybindings are based massively on emacs) but lets not think about that for too long. :P

  • News Portal CMS

    - by George Grigorita
    I am looking for a specific news portal CMS. I know all the major "general" CMS (like WordPress, Drupal or Joomla) and even the less known ones (like TYPO3, Expression Engine, Text Pattern or Concrete5). I'm already working with a Drupal distribution called OpenPublish and another WordPress installation to determine which would be better, but these are more of a Plan B. I would like to work directly with a CMS that was build exactly for this kind of tasks specific to a news / media portal. It doesn't matter if the CMS is commercial (however, I don't want to pay a monthly fee) or free, but I need to be able to use it on my own server / hosting and I need to be able to access it's source code (not to modify it, but to integrate it with future plugins / modules). If you know any CMS that qualifies for this job, please let me know. In the last few days I was all over Google but I couldn't anything worth mentioning.

  • Ubuntu on AMD based Sony Vaio VPCY B15AG

    - by Gaurav
    Last week I bought a AMD E350 (AMD Fusion platform) based Sony VAIO (VPCYB15AG) having AMD Radeon HD 6310 graphics, I removed Windows that came along with and installed Ubuntu 10.10 (AMD64) using USB drive. During installation my touchpad was not working, I managed through keyboard, but after completing installation & restarting the machine still there was no touchpad support. Also there's no proper graphic card drivers. Even I tried connecting the USB mouse to it but the left key is not working and had to configure the mouse as left-hand to get the left click enabled. I tried searching for any possible solutions for these but found nothing helpful, is there any hope? What should I do to enable i) enable touch pad support ii) get higher resolution 1366x768, etc?

  • Visual NHibernate Update

    - by Ricardo Peres
    I have previously talked about Visual NHibernate. It has grown since last time, now offering support for multiple databases (SQL Server, Oracle, MySQL, PostgreSQL, Firebird), generates projects from existing databases or from existing Visual Studio projects and produces XML or Fluent mappings, to name just a few. To me it is by far the most interesting tools for working with NHibernate I know of (granted, I haven't tried NHibernate Profiler). For a limited period, Slyce Software is offering a 30% discount, until the final version is released, so you may want to have a look. Please note that I am in no way related to Slyce, but made some feature requests which have been implemented (thanks, Gareth!).

  • Is there a way to use something similar to a capture group for apache2 server name

    - by Zipper
    I have a server that sits behind an AWS load balancer. The LB can't do automatic redirect from HTTP to HTTPs, and the LB is doing my SSL. So I need to setup apache on my servers to redirect any request on port 80 to https://FOOBAR m where FOOBAR is the domain that came in. I haven't been able to find a way of doing that so far. I'm an apache newb though. What I'm trying to do is something similar to this. I'll use regex as an example <VirtualHost *:80> ServerName (.*) Redirect / https://\1 </VirtualHost> If there's a better way to do this, please let me know. EDIT: Sorry I should have explained why this is happening. I actually have a tomcat server running my app on port 8080, and the LB points to that. From what I can tell so far my requests come in on http (which is expected), but when my app server sends redirects (for login purposes) it tries to redirect to http, instead of https. I haven't had a chance to fully investigate this, but I wanted to work around it for now by point the LB to point to the apache server, and have any port 80 requests redirect to 443. EDIT2: The other reason I'm interested in doing this, is that since the LB can't do the redirect, I need to have another redirect mechanism in place to tell the browser to go to https://FOOBAR

  • That pestky Intel Centrino wireless N + WiMAX 6150 wireless card

    - by newb26
    I'm new to linix and just got Ubuntu up and running on my ASUS laptop last night. Aside from the wireless everything seems to be working. The card is able to recognize networks but cannot make a full connection. After I enter my password it will try to connect before asking for the password again after a few minutes. I know the issue isn't the password because I checked that I had the right one. I've done some poking around trying to find a way to get it work. Linix recognizes the card as well. I found a link to some drivers in a question someone had about a WiMAX 6250 card and am curious if anyone knows if they would also work for the 6150 I have in my machine: https://github.com/ago/wimax-tools If not what can I do?

  • Whoosh: PASS Board Year 1, Q4

    - by Denise McInerney
    "Whoosh". That's the sound the last quarter of 2012 made as it rushed by. My first year on the PASS Board is complete, and the last three months of it were probably the busiest. PASS Summit 2012 Much of October was devoted to preparing for Summit. Every Board  member, HQ staffer and dozens of volunteers were busy in the run-up to our flagship event. It takes a lot of work to put on the Summit. The community meetings,  first-timers program, keynotes, sessions and that fabulous Community Appreciation party are the result of many hours of preparation. Virtual Chapters at the Summit With a lot of help from Karla Landrum, Michelle Nalliah, Lana Montgomery and others at HQ the VCs had a good presence at Summit. We started the week with a VC leaders meeting. I shared some information about the activities and growth during the first part of the year.   From January - September 2012: The number of VCs increased from 14 to 20 VC membership  grew from 55,200 to 80,100 Total attendance at VC meetings increased from 1,480 to 2,198 Been part of PASS Global Growth with language-based VC- including Chinese, Spanish and Portuguese. We also heard from some VC leaders and volunteers. Ryan Adams (Performance VC) shared his tips for successful marketing of VC events. Amy Lewis (Business Intelligence VC) described how the BI chapter has expanded to support PASS' global growth by finding volunteers to organize events at times that are convenient for people in Europe and Australia. Felipe Ferreira (Portuguese language VC) described the experience of building a user group first in Brazil, then expanding to work with Portuguese-speaking data professionals around the world. Virtual Chapter leaders and volunteers were in evidence throughout Summit, beginning with the Welcome Reception. For the past several years VCs have had an organized presence at this event, signing up new members and advertising their meetings. Many VC leaders also spent time at the Community Zone. This new addition to the Summit proved to be a vibrant spot were new members and volunteers could network with others and find out how to start a chapter or host a SQL Saturday. Women In Technology 2012 was the 10th WIT Luncheon to be held at Summit. I was honored to be asked to be on the panel to discuss the topic "Where Have We Been and Where are We Going?" The PASS community has come a long way in our understanding of issues facing women in tech and our support of women in the organization. It was great to hear from panelists Stefanie Higgins and Kevin Kline who were there at the beginning as well as Kendra Little and Jen Stirrup who are part of the progress being made by women in our community today. Bylaw Changes The Board spent a good deal of time in 2012 discussing how to move our global growth initiatives forward. An important component of this is a proposed change to how the Board is elected with some seats representing geographic regions. At the end of December we voted on these proposed bylaw changes which have been published for review. The member review and feedback is open until February 8. I encourage all members to review these changes and send any feedback to [email protected]  In addition to reading the bylaws, I recommend reading Bill Graziano's blog post on the subject. Business Analytics Conference At Summit we announced a new event: the PASS Business Analytics Conference. The inaugural event will be April 10-12, 2013 in Chicago. The world of data is changing rapidly. More and more businesses want to extract value and insight from their data. Data professionals who provide these insights or enable others to do so are in demand. The BA Conference offers expert content on predictive analytics, data exploration and visualization, content delivery strategies and more. By holding this new event PASS is participating in important discussions happening in our industry, offering our members more educational value and reaching out to data professionals who are not currently part of our organization. New Year, New Portfolio In addition to my work with the Virtual Chapters I am also now responsible for the 24 Hours of PASS portfolio. Since the first 24HOP of 2013 is scheduled for January 30 we started the transition of the portfolio work from Rob Farley to me right after Summit. Work immediately started to secure speakers for the January event. We have also been evaluating webinar platforms that can be used for 24HOP as well as the Virtual Chapters. Next Up 24 Hours of PASS: Business Analytics Edition will be held on January 30. I'll be there and will moderate one or two sessions. The 24HOP topics are a sneak peek into the type of content that will be offered at the Business Analytics Conference. I hope to see some of you there. The Virtual Chapters have hit the ground running in 2013; many of them have events scheduled. The Application Development VC is getting restarted  and a new Business Analytics VC will be starting soon. Check out the lineup and join the VCs that interest you. And watch the Events page and Connector for announcements of upcoming meetings. At the end of January I will be attending a Board meeting in Seattle, and February 23 I will be at SQL Saturday #177 in Silicon Valley.

  • JavaOne and Oracle Open World Community Run - Monday, Oct 1, 6:17am PT

    - by arungupta
    Following the tradition from last year, inviting all JavaOne and Oracle Open World attendees to run with me in one of the 10 best cities to run in the US. The running route will start at Ferry Plaza on Embarcadero, go through Fisherman's Wharf, straight up Hyde St, couple of loops around Crooked Street and then back the same route to end at Ferry Plaza. Here is the complete clickable map: The Hyde Street (~300ft in 0.75 miles) and Lombard (~200 ft in 0.15 mile) are challenging elevations and you may cover them once only. Alternatively you may take a simpler route out-and-back by running further up to Marina and Crissy Field. When ? Monday, Oct 1, 2012 I plan to leave at 6:17am PT from the starting point and certainly hope you can join me. Oracle is doing several things to keep Oracle Open World and JavaOne sustainable and reduce the conference footprint. Lets do our share to keep the conference green! Of course, don't forget the Geek Bike Ride is tomorrow.

  • Why did Alan Kay say, "The Internet was so well done, but the web was by amateurs"?

    - by kalaracey
    OK, so I paraphrased. The full quote: The Internet was done so well that most people think of it as a natural resource like the Pacific Ocean, rather than something that was man-made. When was the last time a technology with a scale like that was so error-free? The Web, in comparison, is a joke. The Web was done by amateurs. -- Alan Kay. I am trying to understand the history of the Internet and the web, and this statement is hard to understand. I have read elsewhere that the Internet is now used for very different things than it was designed for, and so perhaps that factors in. What makes the Internet so well done, and what makes the web so amateurish? (Of course, Alan Kay is fallible, and no one here is Alan Kay, so we can't know precisely why he said that, but what are some possible explanations?) *See also the original interview*.

  • Is it possible to prioritize which folders get synced first when using Ubuntu One?

    - by Philippe
    I face the problem that u1 syncs my files to a given order. I'd like to change that order. Consider that: On a week end I work and I may also copy the content of my photo SD card onto my notebook. The next time I boot my work computer, I might be sitting there and waiting for some hours until U1 synced/downloaded all the photos to my workstation and the files I need for work are the last in the '--waiting' list. I don't mind if Ubuntu One is a slow downloader, I would be just happy if I could define that all files in a certain folder (and all of it subfolders) always need to be downloaded first. I'm aware that there was once the possibility to move some files to the beginning of the sync list. But that was a very clumsy way with providing the folder id etc. and in the current version of u1 I can't even find it any more. Any suggestions on how to prioritize always the same folder?

  • SQL SERVER – Finding Latch Statistics

    - by pinaldave
    Last month I wrote SQL Server Wait Types and Queues series SQL SERVER – Summary of Month – Wait Type – Day 28 of 28. I had great fun to write the series. I learned a lot and I felt this has created some deep interest on the subject with others. I recently received very interesting question from one of the reader after reading SQL SERVER – PAGELATCH_DT, PAGELATCH_EX, PAGELATCH_KP, PAGELATCH_SH, PAGELATCH_UP – Wait Type – Day 12 of 28 that if they can know what kind of latches are waiting and what is their count. Absolutely! SQL Server team has already provided DMV which does the same. -- Latch SELECT * FROM sys.dm_os_latch_stats ORDER BY wait_time_ms DESC Above script will return you details about how many latches were waiting for how long. After going over this script I feel like going deep into the subject further. I will post a blog post on the subject soon.

  • Geometry shader for multiple primitives

    - by Byte56
    How can I create a geometry shader that can handle multiple primitives? For example when creating a geometry shader for triangles, I define a layout like so: layout(triangles) in; layout(triangle_strip, max_vertices=3) out; But if I use this shader then lines or points won't show up. So adding: layout(triangles) in; layout(triangle_strip, max_vertices=3) out; layout(lines) in; layout(line_strip, max_vertices=2) out; The shader will compile and run, but will only render lines (or whatever the last primitive defined is). So how do I define a single geometry shader that will handle multiple types of primitives? Or is that not possible and I need to create multiple shader programs and change shader programs before drawing each type?

  • How do I run a stable Windows XP kvm guest on Ubuntu 10.04?

    - by Jean-Paul Calderone
    I have three Windows XP guests running on a recently upgraded 64-bit Ubuntu 10.04 system. Occasionally (on the order of once every few days), one of the guests will become non-responsive and the kvm process on the host which is running that guest will start consuming 100% CPU. It will continue to do so until it is killed. When restarted, it will be fine for a while, and then the issue repeats. The kvm command line used to run all three guests is this: /usr/bin/kvm -S -M pc-0.12 -enable-kvm -m 1024 -smp 1 -name bigdog21vmxp1 \ -uuid ea47ff84-125b-16f7-9a4d-a6d0d8bab46a \ -chardev socket,id=monitor,path=/var/lib/libvirt/qemu/bigdog21vmxp1.monitor,server,nowait \ -monitor chardev:monitor \ -localtime \ -boot c \ -drive file=/var/lib/libvirt/images/windowsxp-1.qcow2,if=ide,index=0,boot=on,format=qcow2 \ -net nic,macaddr=54:52:00:02:06:0e,vlan=0,name=nic.0 \ -net tap,fd=58,vlan=0,name=tap.0 \ -chardev pty,id=serial0 \ -serial chardev:serial0 \ -parallel none \ -usb \ -usbdevice tablet \ -vnc 127.0.0.1:1 \ -k en-us \ -vga cirrus \ -soundhw es1370 Why do the systems misbehave this way sometimes? And what configuration can I change in order to fix it? Or, if the problem is due to a bug in kvm, what is the process for isolating a kvm failure so that the developers have a chance of fixing it?

  • Adobe flash plug-in crashed/needs permission in Chromium

    - by sally
    A couple of days ago I started to get these messages when trying to watch videos on Youtube and a couple of other sites. (Using Chromium browser) Normally starts by just seeing a black screen with Missing Plug-in faintly visible, but will also ask me to give permission to run both at top (yellow bar), and if I tell it to 'allow' it follows up with the white puzzle piece on black background requesting permission. Occasionally I have seen the message telling me the flash-player has crashed, too. Giving permission does not fix the problem. Have also navigated to 'about:plugins' and checked that Adobe flash is enabled and permitted. I have just done a fresh installation of Lubuntu 11.10 as a last resort but problem still not fixed.

  • WIF, ADFS 2 and WCF&ndash;Part 6: Chaining multiple Token Services

    - by Your DisplayName here!
    See the previous posts first. So far we looked at the (simpler) scenario where a client acquires a token from an identity provider and uses that for authentication against a relying party WCF service. Another common scenario is, that the client first requests a token from an identity provider, and then uses this token to request a new token from a Resource STS or a partner’s federation gateway. This sounds complicated, but is actually very easy to achieve using WIF’s WS-Trust client support. The sequence is like this: Request a token from an identity provider. You use some “bootstrap” credential for that like Windows integrated, UserName or a client certificate. The realm used for this request is the identifier of the Resource STS/federation gateway. Use the resulting token to request a new token from the Resource STS/federation gateway. The realm for this request would be the ultimate service you want to talk to. Use this resulting token to authenticate against the ultimate service. Step 1 is very much the same as the code I have shown in the last post. In the following snippet, I use a client certificate to get a token from my STS: private static SecurityToken GetIdPToken() {     var factory = new WSTrustChannelFactory(         new CertificateWSTrustBinding(SecurityMode.TransportWithMessageCredential,         idpEndpoint);     factory.TrustVersion = TrustVersion.WSTrust13;       factory.Credentials.ClientCertificate.SetCertificate(         StoreLocation.CurrentUser,         StoreName.My,         X509FindType.FindBySubjectDistinguishedName,         "CN=Client");       var rst = new RequestSecurityToken     {         RequestType = RequestTypes.Issue,         AppliesTo = new EndpointAddress(rstsRealm),         KeyType = KeyTypes.Symmetric     };       var channel = factory.CreateChannel();     return channel.Issue(rst); } To use a token to request another token is slightly different. First the IssuedTokenWSTrustBinding is used and second the channel factory extension methods are used to send the identity provider token to the Resource STS: private static SecurityToken GetRSTSToken(SecurityToken idpToken) {     var binding = new IssuedTokenWSTrustBinding();     binding.SecurityMode = SecurityMode.TransportWithMessageCredential;       var factory = new WSTrustChannelFactory(         binding,         rstsEndpoint);     factory.TrustVersion = TrustVersion.WSTrust13;     factory.Credentials.SupportInteractive = false;       var rst = new RequestSecurityToken     {         RequestType = RequestTypes.Issue,         AppliesTo = new EndpointAddress(svcRealm),         KeyType = KeyTypes.Symmetric     };       factory.ConfigureChannelFactory();     var channel = factory.CreateChannelWithIssuedToken(idpToken);     return channel.Issue(rst); } For this particular case I chose an ADFS endpoint for issued token authentication (see part 1 for more background). Calling the service now works exactly like I described in my last post. You may now wonder if the same thing can be also achieved using configuration only – absolutely. But there are some gotchas. First of all the configuration files becomes quite complex. As we discussed in part 4, the bindings must be nested for WCF to unwind the token call-stack. But in this case svcutil cannot resolve the first hop since it cannot use metadata to inspect the identity provider. This binding must be supplied manually. The other issue is around the value for the realm/appliesTo when requesting a token for the R-STS. Using the manual approach you have full control over that parameter and you can simply use the R-STS issuer URI. Using the configuration approach, the exact address of the R-STS endpoint will be used. This means that you may have to register multiple R-STS endpoints in the identity provider. Another issue you will run into is, that ADFS does only accepts its configured issuer URI as a known realm by default. You’d have to manually add more audience URIs for the specific endpoints using the ADFS Powershell commandlets. I prefer the “manual” approach. That’s it. Hope this is useful information.

  • Project Coin: JSR 334 has a Proposed Final Draft

    - by darcy
    Reaching nearly the last phase of the JCP process, JSR 334 now has a proposed final draft. There have been only a few refinements to the specification since public review: Incorporated language changes into JLS proper. Forbid combining diamond and explicit type arguments to a generic constructor. Removed unusual protocol around Throwable.addSuppressed(null) and added a new constructor to Throwable to allow suppression to be disabled. Added disclaimers that OutOfMemoryError, NullPointerException, and ArithmeticException objects created by the JVM may have suppression disabled. Added thread safely requirements to Throwable.addSuppressed and Throwable.getSuppressed. Next up is the final approval ballot; almost there!

  • How to give wife emergency access to logins, passwords, etc.?

    - by Torben Gundtofte-Bruun
    I'm the digital guru in my household. My wife is good with email and forum websites but she trusts me with all our important digital stuff -- such as online banking and other things that require passwords, but also family photos and the plethora of other digital things in a modern home. We discuss relevant actions but it's always me that executes the actions. If I should get "hit by a bus" then my wife would be thoroughly stranded -- she would have no idea what digital stuff is where on our computer, how to access it, what online accounts we have, and their login credentials are. It would also leave my many public appearances (personal websites, email accounts, social networks, etc.) unresolved. To complicate things, I'm one of those people who don't use password as my password everywhere; I use a mix of SuperGenPass and LastPass, and also two-factor authentication whenever possible. I don't have much hope that she would find her way through a written explanation of all that in a stressful situation. I could just tell her that she should ask my tech-savvy twin brother and then entrust him with my LastPass master passphrase. I feel that would have a high chance of success, but it's inelegant and leaves my wife without control of the information. How can I ensure that my wife has access to my digital remains?

  • SQL SERVER – Weekly Series – Memory Lane – #053 – Final Post in Series

    - by Pinal Dave
    It has been a fantastic journey to write memory lane series for an entire year. This series gave me the opportunity to go back and see what I have contributed to this blog throughout the last 7 years. This was indeed fantastic series as this provided me the opportunity to witness how technology has grown throughout the year and how I have progressed in my career while writing this blog post. This series was indeed fantastic experience readers as many joined during the last few years and were not sure what they have missed in recent years. Let us continue with the final episode of the Memory Lane Series. Here is the list of selected articles of SQLAuthority.com across all these years. Instead of just listing all the articles I have selected a few of my most favorite articles and have listed them here with additional notes below it. Let me know which one of the following is your favorite article from memory lane. 2007 Get Current User – Get Logged In User Here is the straight script which list logged in SQL Server users. Disable All Triggers on a Database – Disable All Triggers on All Servers Question : How to disable all the triggers for a database? Additionally, how to disable all the triggers for all servers? For answer execute the script in the blog post. Importance of Master Database for SQL Server Startup I have received following questions many times. I will list all the questions here and answer them together. What is the purpose of Master database? Should our backup Master database? Which database is must have database for SQL Server for startup? Which are the default system database created when SQL Server 2005 is installed for the first time? What happens if Master database is corrupted? Answers to all of the questions are very much related. 2008 DECLARE Multiple Variables in One Statement SQL Server is a great product and it has many features which are very unique to SQL Server. Regarding feature of SQL Server where multiple variable can be declared in one statement, it is absolutely possible to do. 2009 How to Enable Index – How to Disable Index – Incorrect syntax near ‘ENABLE’ Many times I have seen that the index is disabled when there is a large update operation on the table. Bulk insert of very large file updates in any table using SSIS is usually preceded by disabling the index and followed by enabling the index. I have seen many developers running the following query to disable the index. 2010 List of all the Views from Database Many emails I received suggesting that they have hundreds of the view and now have no clue what is going on and how many of them have indexes and how many does not have an index. Some even asked me if there is any way they can get a list of the views with the property of Index along with it. Here is the quick script which does exactly the same. You can also include many other columns from the same view. Minimum Maximum Memory – Server Memory Options I was recently reading about SQL Server Memory Options over here. While reading this one line really caught my attention is minimum value allowed for maximum memory options. The default setting for min server memory is 0, and the default setting for max server memory is 2147483647. The minimum amount of memory you can specify for max server memory is 16 megabytes (MB). 2011 Fundamentals of Columnstore Index There are two kinds of storage in a database. Row Store and Column Store. Row store does exactly as the name suggests – stores rows of data on a page – and column store stores all the data in a column on the same page. These columns are much easier to search – instead of a query searching all the data in an entire row whether the data are relevant or not, column store queries need only to search a much lesser number of the columns. How to Ignore Columnstore Index Usage in Query In summary the question in simple words “How can we ignore using the column store index in selective queries?” Very interesting question – you can use I can understand there may be the cases when the column store index is not ideal and needs to be ignored the same. You can use the query hint IGNORE_NONCLUSTERED_COLUMNSTORE_INDEX to ignore the column store index. The SQL Server Engine will use any other index which is best after ignoring the column store index. 2012 Storing Variable Values in Temporary Array or Temporary List SQL Server does not support arrays or a dynamic length storage mechanism like list. Absolutely there are some clever workarounds and few extra-ordinary solutions but everybody can;t come up with such solution. Additionally, sometime the requirements are very simple that doing extraordinary coding is not required. Here is the simple case. Move Database Files MDF and LDF to Another Location It is not common to keep the Database on the same location where OS is installed. Usually Database files are in SAN, Separate Disk Array or on SSDs. This is done usually for performance reason and manageability perspective. Now the challenges comes up when database which was installed at not preferred default location and needs to move to a different location. Here is the quick tutorial how you can do it. UNION ALL and ORDER BY – How to Order Table Separately While Using UNION ALL If your requirement is such that you want your top and bottom query of the UNION resultset independently sorted but in the same result set you can add an additional static column and order by that column. Let us re-create the same scenario.
