• How to check whether a default browser is opened in the operating system (Java)?

  - by stempel1984

  Hi, I am newbie here. During my work, I faced an interesting problem. I need to: check whether a default html browser is opened; check whether the browser is minimized/maximized (simply, a window's state); get an url address typed in the browser. If any of these conditions is not met, I have to open the browser in a maximized view with a desired url address. I primarily wanted to do all this in Java, but it came to my mind that I should employ many techniques/technologies and combine them appropriately to complete the functionality. But, which ones? That's the problem. I just recalled Windows API, but I'm not sure if it is of any help... Some users on another forum suggested that I should consider JNI (no experience at all)... I only know how to open a default browser (e.g. with use of the 'browse(URI uri)' method of the 'java.awt.Desktop' class) - that's too little to be proud of. Please give me some hints, maybe links to reasonable discussions, I would greatly appreciate any suggestions how to approach the problem.

• comparision of strings

  - by EmiLazE

  i am writing a program, that simulates game mastermind. but i am struggling on how to compare guessed pattern to key pattern. the game conditions are a little bit changed: patterns consist of letters. if an element of guessed pattern is equal to element of key pattern, and also index is equal, then print b. if an element of guessed pattern is equal to element of key pattern, but index is not, then print w. if an element of guessed pattern is not equal to element of key pattern, print dot. in feedback about guessed pattern, 'b's come first, 'w's second, '.'s last. my problem is that i cannot think of a way totally satisfies the answer. for (i=0; i<patternlength; i++) { for (x=0; x<patternlength; x++) { if (guess[i]==key[x] && i==x) printf("b"); if (guess[i]==key[x] && i!=x) printf("w"); if (guess[i]!=key[x]) printf("."); } }

• How to find next (by a single parameter) element in c++? (stl) [closed]

  - by user2136963

  I have n humans of THuman class Each human has scored some points in one of two rounds. (score1 and score2) Each human has its unique id. Score1 and 2 are also unique. Besides, a human has a score_t=score1+score2, which can be the same for two of them. I need to implement 6 variables to THuman which return id of a human with: bigger score1 smaller score1 bigger score2 smaller score2 bigger score_t smaller score_t (if there are many humans those satisfy theese conditions, the one with smallest difference of corresponding parameter should be chosen (like score1 for 1 and 2)) In other words, it's some kind of storing 3 human sortings. Two more functions I need should get argument x, set score1 or score 2 to x, and then refresh some of the 6 variables above. If I needed sorting by only one variable, I would simply create set and defined and < operators for my class. But what is the solution for three of parameters? Is it possible to use STL here, or I should create my own lists/treaps? __ Answer: How to update set of pointers c++?

• What is the difference between Anycast and GeoDNS / GeoIP wrt HA?

  - by Riyad

  Based on the Wikipedia description of Anycast, it includes both the distribution of a domain-name-to-many-IP-mapping across many DNS servers as well as replying to clients with the most geographically close (or fastest) server. In the context of a globally distributed, highly available site like google.com (or any CDN service with many global edge locations) this sounds like the two key features one would need. DNS services like Amazon's Route53, EasyDNS and DNSMadeEasy all advertise themselves as Anycast-enabled networks. Therefore my assumption is that each of these DNS services transparently offer me those two killer features: multi-IP-to-domain mapping AND routing clients to the closest node. However, each of these services seem to separate out these two functionalities, referring to the 2nd one (routing clients to closest node) as "GeoDNS", "GeoIP" or "Global Traffic Director" and charge extra for the service. If a core tenant of an Anycast-capable system is to already do this, why is this functionality being earmarked as this extra feature? What is this "GeoDNS" feature doing that a standard Anycast DNS service won't do (according to the definition of Anycast from Wikipedia -- I understand what is being advertised, just not why it isn't implied already). I get extra-confused when a DNS service like Route53 that doesn't support this nebulous "GeoDNS" feature lists functionality like: Fast – Using a global anycast network of DNS servers around the world, Route 53 is designed to automatically route your users to the optimal location depending on network conditions. As a result, the service offers low query latency for your end users, as well as low update latency for your DNS record management needs. ... which sounds exactly like what GeoDNS is intended to do, but geographically directing clients is something they explicitly don't support it yet. Ultimately I am looking for the two following features from a DNS provider: Map multiple IP addresses to a single domain name (like google.com, amazon.com, etc. does) Utilize a DNS service that will respond to client requests for that domain with the IP address of the nearest server to the requestee. As mentioned, it seems like this is all part of an "Anycast" DNS service (all of which these services are), but the features and marketing I see from them suggest otherwise, making me think I need to learn a bit more about how DNS works before making a deployment choice. Thanks in advance for any clarifications.

• uploading via http post (multipart/form-data) silently fails with big files

  - by matteo

  When uploading multipart/form-data forms via a http post request to my apache web server, very big files (i.e. 30MB) are silently discarded. On the server side all looks as if the attached file was received with 0 bytes size. On the client side all looks like it had been uploaded succesfully (it takes the expected long time to upload and the browser gives no error message). On the server, nothing is logged into the error log. An entry is logged into the access log as if everything was ok (a post request and a 200 ok response). These uploads are being posted to a php script. In the php script, If I print_r $_FILES, I see the following information for the relevant file: [file5] => Array ( [name] => MOV023.3gp [type] => video/3gpp [tmp_name] => /tmp/phpgOdvYQ [error] => 0 [size] => 0 ) Note both [error] = 0 (which should mean no error) and [size] = 0 (as if the file was empty). My php script runs fine and receives all the rest of the data except these files. move_uploaded_file succeeds on these files and actually copies them as 0byte files. I've already changed the php directives max_upload_size to 50M and post_max_size to 200M, so neither the single file nor the request exceed any size limit. max_execution_time is not relevant, because the time to transfer the data does not count; and I've increased max_input_time to 1000 seconds, though this shouldn't be necessary since this is the time taken to parse the input data, not the time taken to upload it. Is there any apache configuration, prior to php, that could be causing these files to be discarded even prior to php execution? Some limit in size or in upload time? I've read about a default 300 seconds timeout limit, but this should apply to the time the connection is idle, not the time it takes while actually transferring data, right? Needless to say, uploads with all exactly identical conditions (including file format, client and everything) except smaller file size, work seamlessly, so the issue is clearly related to the file or request size, or to the time it takes to send it.

• What are some fast methods for navigating to frequently used folders in Windows 7?

  - by fostandy

  (This is a followup question from my previous question.) In windows XP I used to be able to quickly navigate to frequently used folders by making use of the 'Favorites' menu item and the hotkey behaviour. In certain conditions it could be set up so that getting to a particular folder was as easy as alt-a x (and without a file explorer window open it was as fast as win-e alt-a x). I am struggling to get anywhere near this speed in Windows 7 and would like to solicit advice from others regarding fast folder navigation to see if I am missing any methods. My current way to navigate quickly is basically move hand to mouse move cursor to navigation pane/pain. scroll all the way to the top (because normally I the panel is focused on whatever deep directory structure I am already in). sift through my 50+ favorites to get the one I want, or click a link to a folder that contains further links in some sort of 'pseudo-tree' functionality. select it. This is slower than my previous method by upwards of an order of magnitude. There are a couple of things I've contemplated: add expandable folders, not just direct links, to the favorites menu. add expandable folders, not just direct links, to the start menu. add links of my favorite folders to a submenu of the start menu so that they come up when I search them. They do but this still rather cumbersome started using 7stacks - url here (I cannot link the url directly due to lack of reputation but http://www.alastria.com/index.php?p=software-7s). This is about the closest I've gotten to some sort of compact, customizeable, easy to access, tree based navigation structure. How do you power users quickly navigate to your favorite folders? Are there keyboard shortcuts I am missing? Can someone recommend other apps or addon or extensions that can achieve this sort of functionality? The Current solution (thanks to the answers below) I am going to use is a combination of Autohotkey and 7stacks - autohotkey to launch 7stacks, 7stacks with the 'menu' stack type for fast, key-enabled navigation to folders organised in a tree structure. This solves about 90% of the issue, the only issues are (note that these are really minor, I am really splitting hairs more than anything here) Can't use this for existing folder navigation (ie already have a explorer window open, want to go to another directory) A bit more cumbersome to add/remove entries to compared to xp favorites. A little slower than xp favorites. Whatever. I'm happy. Thanks guys. I think the answer is a split to John T and Kelbizzle - I've elected to give the answer to John T and +1 to Kelbizzle as I had already mentioned 7stacks.

• Gateway GT5220 Boot/POST Failure

  - by John Rudy

  I have a Gateway GT5220 I'm troubleshooting. It is, in fact, the machine I just gave my father for his birthday a couple months ago. (Prior to that, it was my home PC. My home PC is now the MacBook on which I'm writing this.) Before going any further, I suspect that the answer will be, "It's worse than that, it's dead, Jim, it's dead, Jim, it's dead, Jim." At least, mobo and/or CPU. The initial symptoms were as follows: Turn on power All fans fire up (thus making it so I can't hear if the hard drive is spinning or not, nor are my hands sensitive enough anymore to feel it) No LEDs remained lit on the front panel. (Initially, the hard drive indicator flashed briefly.) No beep, no video, no nothing. Following some advice I found here, I tried to "drain the stored power." After following those steps, the new symptoms were: Turn on power All fans fire up The front panel LEDs remained lit! After about 20, maybe 30 seconds, we had video! Sort of. We got to the Gateway splash/POST screen, which appeared thoroughly corrupted. How corrupted? Well, I imagine it's what a POST screen would look like after reading the wrong passage out of the Necronomicon: It stayed there. I gave it at least 5, maybe 6 minutes, and it didn't move. So I shut her down, started her up again, and now (this is where we currently stand, symptomatically) we have this: Turn on power All fans fire up The front panel LEDs remain lit No video, no beep, no nothing. I'm a software guy; haven't done real hardware troubleshooting in years. My gut tells me that the mobo and/or CPU is fried, and unfortunately my gut didn't get to be as big as it is being wrong all the time. :( In addition to the link above, I have read all of the following (trying to save you some LMGTFY trouble): Gateway Support POST Error Messages and Handling About a zillion (useless) POST beep code sites A kioskea.net post indicating that most likely we're at what I consider "total loss" (mobo and/or CPU) My questions: Are there any conditions other than mobo/CPU that could cause symptoms like these? Is it worth my time to try the next hardware troubleshooting step?(IE, remove all non-critical hardware from the machine, try to boot, systematically replace one by one until we find the failing component) Which mobos will fit in the Gateway GT5220 case (with rear ports correctly aligned)? (Why this is not a dupe: I wouldn't have posted this question if it hadn't been for the funkadelic possessed video display on the one occasion we got video out. I think that justified this not being an exact dupe. Of course, if the community overrules, I will understand.)

• Setting up a very mixed Active Directory network to work with PowerShell Remote Administration

  - by erictheavg

  Summary: I want to be able to monitor the computers on my network, but don't need it to be automated. We're too small to purchase anything like MOM, but too big to do anything manually (~100 machines in two locations). I just keep running into issues, and was wondering if there's a master list of Group Policy settings I can distribute to my environment to get Remote Powershell working. Environment: Our AD network is pretty mixed. The end users have XP SP3, Win 7, and Win 7 x64. The servers include Win2k3 SP2, Win2k8, Win2k8 x64, Win2k8 R2, and Win2k8 R2 x64. Details: I'm trying to get it to work with Remote Powershell, but I run into errors like the following: Connecting to remote server failed with the following error message : The WinRM client cannot process the request. Default authentication may be used with an IP address under the following conditions: the transport is HTTPS or the destination is in the TrustedHosts list, and explicit credentials are provided. Use winrm.cmd to configure TrustedHosts. Note that computers in the TrustedHosts list might not be authenticated. For more information on how to set TrustedHosts run the following command: winrm help config. For more information, see the about_Remote_Troubleshooting Help topic. + CategoryInfo : OpenError: (:) [], PSRemotingTransportException + FullyQualifiedErrorId : PSSessionStateBroken Then I go to the computer (Win2k3 SP2 server) and run winrm quickconfig per the recommendations via google, and it says: Make these changes [y/n]? y WinRM has been updated to receive requests. WinRM service started. WSManFault Message = The client cannot connect to the destination specified in the request. Verify that the service on the destination is running and is accepting requests. Consult the logs and documentation for the WS-Management service running on the destination, most commonly IIS or WinRM. If the destination is the WinRM service, run the following command on the destination to analyze and configure the WinRM service: "winrm quickconfig". Error number: -2144108526 0x80338012 The client cannot connect to the destination specified in the request. Verify that the service on the destination is running and is accepting requests. Consult the logs and documentation for the WS-Management service running on the destination, most commonly IIS or WinRM. If the destination is the WinRM service, run the following command on the destination to analyze and configure the WinRM service: "winrm quickconfig". That's right. It tells me to remedy my winrm quickconfig failure by running winrm quickconfig. I don't want to band-aid this project one google search at a time. I'm sure there is a step-by-step tutorial out there on how to set up a network for powershell remote administration. Does anyone know of one? Books are acceptable. Thanks in advance! I didn't think my question would get this long.

• How can I simulate blocking RTMP over port 80 on Windows?

  - by Christian Nunciato

  It seems like this should be so simple, but since this isn't my area of expertise, I'm having a hell of a time figuring out how to do it. Basically, I have a Flash app and I'm connecting to a Flash Media Server to stream some content. The URL I'm using to do this, for example, looks like this: rtmp://someserver.com/some/path/mp3:somefile Everything works -- but that's sort of the problem. When I'm trying to do is simulate my users attempting to play back my media under more restrictive conditions than the ones I have here (i.e., none) -- namely being stuck behind firewalls or proxy servers that block access to RTMP streams. Flash, according to Adobe, is equipped to handle proxy servers and firewalls automatically, like so (from the docs): When you do not specify a port number in an RTMP address, Flash will attempt to connect to port 1935. If it fails it will then try to connect to port 443; if that fails, it will try port 80. [And if that fails, it will attempt to connect via RTMPT (i.e., HTTP tunneling) on port 80.] So no coding is required to access ports 1935, 443, or port 80 if you do not specify a port in the RTMP address. The problem I'm having is setting up a reliable environment in which to test that this behavior actually happens. I'm on a Windows machine, for example, so with Windows Firewall, I can block certain ports and protocols (1935, 443), but I don't want to block port 80, because the final fallback protocol (RTMPT) is supposed to run on port 80, and Windows Firewall only gives me enough granularity (as far as I know, anyway) to block "all outbound TCP traffic to remote port 80" -- that is, I can't, apparently, block "all outbound RTMP traffic to port 80" while leaving RTMPT traffic to port 80 unaffected. My understanding thus far is that I'll probably need to set up a proxy server to do this. Is this correct? Or is there a simpler way (on Win 7, at least) to filter out RTMP to 1935, RTMP to 443, RTMP to 80, but still allow RTMPT to 80 (where all four hostnames are identical)? And if I do have to set up a proxy server, what's the simplest way to go on Windows? I've set up WinProxy, which seems a bit janky but apparently works -- but then what I can't figure out is how to tell Windows to force all TCP traffic (including RTMP, RTMPT and HTTO) through this proxy server so I can turn around and reject the requests for RTMP. Any help would be hugely appreciated. This isn't my realm of expertise and I've alreasdy spent more time on it than I probably should. :)

• Handling site not found and page not found with dynamic mass virtual hosting

  - by Rick Moynihan

  I have recently setup mass virtual hosting in Apache so that all we need to do is create a directory to create a new vhost. We're then also using wildcard DNS to map all subdomains to the server running our Apache instance. This works excellently, however I'm now having trouble configuring it to fail-over to an appropriate default/error-page when the vhost directory does not exist. The problem appears to be conflated between by my desire to handle the two error conditions: vhost not found i.e. there was no directory found matching the host supplied in the HTTP host header. I'd like this to display an appropriate site not found error page. The 404 page not found condition of the vhost. Additionally I have a specialised "api" vhost in its own vhost block. I've tried a number of variations and none seem to exhibit the behaviour I want. Here's what I'm working with right now: NameVirtualHost *:80 <VirtualHost *:80> DocumentRoot /var/www/site-not-found ServerName sitenotfound.mydomain.org ErrorDocument 500 /500.html ErrorDocument 404 /500.html </VirtualHost> <VirtualHost *:80> ServerName api.mydomain.org DocumentRoot /var/www/vhosts/api.mydomain.org/current # other directives, e.g. setting up passenger/rails etc... </VirtualHost> <VirtualHost *:80> # get the server name from the Host: header UseCanonicalName Off VirtualDocumentRoot /var/www/vhosts/%0/current # other directives ... e.g proxy passing to api etc... ErrorDocument 404 /404.html </VirtualHost> My understanding is that the first vhost block is used as the default, so I have this here as my catch all site. Next I have my API vhost, and then finally my mass vhost block. So for a domain that doesn't match the first two ServerName's and has no corresponding directory in /var/www/vhosts/ I'd expect it to fall-over to the first vhost, however with this setup, all domains resolve to my default site-not-found. Why is this? By putting the mass-vhost block first, I can get the mass-vhosts to resolve properly, but not my site-not-found vhost... and in this case I can't seem to find a way to distinguish between a page-level 404 in the vhost, and the case where the VirtualDocumentRoot fails to find a vhost directory (this appears to use the 404 also). Any help out of this bind is much appreciated!

• Deployment/provisioning tool for commercial applications (not developed in-house)

  - by mfinni

  I help manage a few hosted commercial applications, and we have a lot of manual processes involved when doing new customer-instance deployments into the shared (multitenant) environment. Allow me to describe the most relevant features, and then we can talk about the tools. We have an application on AIX, that requires dozens of changes to config files (some plain text, some XML) as well as a good number of commands to be run on multiple servers - some to start the new instance, some to restart our shared authentication and reporting engines, etc. The config changes follow templates, of course. The servers in question will also depend on the initial conditions specified by the implementer/deployer - we may choose to deploy a given customer to our servers in Europe, or one set of servers may be active-active whereas a different set of servers is active-passive - in short, there's a lot of complications. We have another application that run on IIS 6 and SQL. The DBAs don't want any automation of the SQL components and that's fine with me, but automating the IIS bit would be great. For a new customer instance, we make a filesystem copy of a template Virtual Directory target named after the new customer, make a new AppPool to match, edit a VirDir template .xml file to replace the filepaths and AppPool names with the new ones, and then make a new VirDir from the modified template XML to point to the new filesystem folder and app pool. For the first case, something like ControlTier or Chef might be good. For the second, the new(ish) Web Deploy from MS would probably do a good job. Has anyone used these tools or others to do something similar for applications? More of a nice-to-have, not a fixed requirement - Has anyone used anything that works on both platforms? I'm looking for something free, because the official word is that within a year, we will have whatever HP has renamed the OpsWare suite, which should be able to do stuff like this. Edit - based on someone's suggestion, looking at CFengine for the AIX application, it doesn't seem to address my pain. The problem isn't keeping a given config synced across dozens of servers, we have rsync for that. The problem is that onboarding a new customer instance touches dozens of files, putting pieces of the same or similar information into them - some are new stanzas in existing files, some are new files, and some are new directories. This is a several-hours-long process that is also error-prone because it's mostly done by hand. I guess I'm looking for config-file generation and management. I have built a small Perl script to do something similar for a much smaller case - it binds a CSV file into variables, and then does a copy-and-search-and-replace from a set of template config files. I could probably do the same here.

• Problem with several USB devices on Windows XP. How to diagnose USB device?

  - by Lukasz Baran

  Hello All, Recently I've bought some electronic devices (like e.g. Sony Ebook reader PRS-600 or HP PDA IPaq) which are connected to PC using USB ports. These devices have own batteries and they are recharged using USB. However, I am experiencing a problem with Ebook Reader and the similiar thing happens with my PDA (but in this case it's more rare). Sometimes, I am unable to make it start recharging, when it's connected to USB port. The LCD diode on my Reader lights up and the icon in the system tray appears. They both indicate that the device has been connected. However, the device should start recharching and it should appear on Windows XP as a 'explorable' device (just like pendrive it offers some HDDs). None of these happens:( This problem appears on two PCs - desktop and laptop. Both have Windows XP SP3 installed. And what's interesting and surprising to me is the fact that these devices sometimes work without any problems. I mean, I just plug them in and they work properly. Besides that, there are some computers (I have tested a variety of possible conditions) on which the problem does not appear! I am confused and, on the other hand, determined to find out what is the real cause of such strange behavior. Maybe I'm wrong but I always assumed that I'm using deterministic machines, but the described situation makes me feel like I was dreaming:) And that's why I'm asking you here. Are there any tools that could help me diagnose USB ports? Or maybe anyone knows the solution? I have a lot experience with low level programming (mostly from the times of MS-DOS applications), but I'm not an expert when it comes to WinXP technology. If this was a problem with network connection, I would know what to do - I know how to track network traffic, but with USB ports I feel powerless. I have a feeling that the problem may lie in a way WinXP handles USB devices. Personally, I hate auto-discovery and P'n'P features available in Windows. I know that some of may suggest to move to Linux or other *Nix system. Unfortunately, I have to use WinXP in my professional life, so it's rather impossible. Besides that, I don't consider XP as a total disaster. Any help from you will be appreciated!

• mixing different technologies using ARR reverse proxy

  - by Jaepetto

  I'm currently trying to put together a proof of concept on mixing various technologies onto one web site in order to ease migrations and add flexibility. The idea is to create one 'mashup' site behind an IIS 7.5 ARR reverse proxy. For the time being the ARR reverse proxy forwards all request to our main site. The request are as follow: client -> ARR: Get / ARR -> Server 1: Get / Server 1 -> ARR: 200: /index.htm ARR -> client: 200: /index.htm ...so far so good. Let's say, I want to add a new site (root of another server) as a subsite of my main website. a simple inbound rule does the trick: <rule name="sub1" stopProcessing="true"> <match url="^mySubsite(.*)" /> <conditions logicalGrouping="MatchAll" trackAllCaptures="false" /> <action type="Rewrite" url="http://server2/{R:1}" /> </rule> The requests now are: client -> ARR: Get /mySubsite ARR -> Server 2: Get / Server 2 -> ARR: 200: /index.htm ARR -> client: 200: /index.htm ... still ok. The issue comes when the site on server2 sends a redirection (e.g. to a login page). In the case of SharePoint, it will redirect the user to: /_layouts/Authenticate.aspx?Source=%2F ...which does not exists: client -> ARR: Get /mySubsite ARR -> Server 2: Get / Server 2 -> ARR: 301: /_layouts/Authenticate.aspx?Source=%2F ARR -> client: 301: /_layouts/Authenticate.aspx?Source=%2F client -> ARR: Get /_layouts/Authenticate.aspx?Source=%2F ARR -> client: 404: Not Found Does anyone know a way write the outbound rule to rewrite the response from server 2 "301: /_layouts/Authenticate.aspx?Source=%2F" to "301: /mySubsite/_layouts/Authenticate.aspx?Source=%2FmySubsite%2F"?

• mod_rewrite all but two files causing loop

  - by mpounsett

  I'm trying to set up a web site to allow the creation of a semaphore file to close the site. The logic I want to follow is: when the semaphore file exists and the request is not for /style.css or /favicon.icon show the content of /closed.html I have 1 and 3 working, but my exceptions for 2 result in a processing loop when style.css or favicon.ico are requested. This is my most recent attempt: RewriteEngine on RewriteCond %{REQUEST_URI} !^/style.css RewriteCond %{REQUEST_URI} !^/favicon.ico RewriteCond /usr/local/etc/site/closed -f RewriteRule ^.*$ /closed.html [L] This is in a VirtualHost block, not in a Directory. There is no .htaccess file in play. I have also recently tried this, based on an answer I found elsewhere, but with the same (looping) result: RewriteCond %{REQUEST_URI} ^/style.css [OR] RewriteCond %{REQUEST_URI} ^/favicon.ico RewriteRule ^.*$ - [L] RewriteCond /usr/local/etc/site/closed -f RewriteRule ^.*$ /closed.html [L] I expect a request for /style.css or /favicon.ico to fail to match one of the first two rewrite conditions, which should prevent the URI from being rewritten, which should stop the mod_rewrite iteration. However, mod_rewrite seems to think the URI has been rewritten in those cases, and iterates over the rules again (and again, and again). The above works properly in all cases except for style.css or favicon.ico. In those cases I exceed the loop limits. What am I missing here to cause the rewrite iteration to stop when someone requests style.css or favicon.ico? EDIT: Here's a loglevel 9 example of what happens using the first ruleset when a request arrives for /style.css. This is just the first two iterations.. it continues to loop identically until the limit is reached. 2001:4900:1044:0:145f:826e:6436:dc1 - - [29/May/2014:15:29:26 +0000] [host.example/sid#80c1c48b0][rid#80c1db0a0/initial] (2) init rewrite engine with requested uri /style.css 2001:4900:1044:0:145f:826e:6436:dc1 - - [29/May/2014:15:29:26 +0000] [host.example/sid#80c1c48b0][rid#80c1db0a0/initial] (3) applying pattern '^.*$' to uri '/style.css' 2001:4900:1044:0:145f:826e:6436:dc1 - - [29/May/2014:15:29:26 +0000] [host.example/sid#80c1c48b0][rid#80c1db0a0/initial] (4) RewriteCond: input='/style.css' pattern='!^/style.css' => not-matched 2001:4900:1044:0:145f:826e:6436:dc1 - - [29/May/2014:15:29:26 +0000] [host.example/sid#80c1c48b0][rid#80c1db0a0/initial] (1) pass through /style.css 2001:4900:1044:0:145f:826e:6436:dc1 - - [29/May/2014:15:29:26 +0000] [host.example/sid#80c1c48b0][rid#80c1dd0a0/initial] (2) init rewrite engine with requested uri /style.css 2001:4900:1044:0:145f:826e:6436:dc1 - - [29/May/2014:15:29:26 +0000] [host.example/sid#80c1c48b0][rid#80c1dd0a0/initial] (3) applying pattern '^.*$' to uri '/style.css' 2001:4900:1044:0:145f:826e:6436:dc1 - - [29/May/2014:15:29:26 +0000] [host.example/sid#80c1c48b0][rid#80c1dd0a0/initial] (4) RewriteCond: input='/style.css' pattern='!^/style.css' => not-matched 2001:4900:1044:0:145f:826e:6436:dc1 - - [29/May/2014:15:29:26 +0000] [host.example/sid#80c1c48b0][rid#80c1dd0a0/initial] (1) pass through /style.css

• Create an iTunes Account without a credit card

  - by Matthew Guay

  iTunes Store offers a large variety of free content, but to download it you have to have an account. Usually you have to enter your credit card information to sign up, but here’s an easy way to get an iTunes account for free downloads without entering any payment info. Although iTunes Store is known for paid downloads of movies, music, and more, it also has a treasure trove of free media.  Some of it, including Podcasts and iTunes U educational content do not require an account to download.  However, any other free content, including free iPhone/iPod Touch apps and free or promotional music, videos, and TV Shows all require an account to download.  If you try to download a free movie or music download, you will be required to enter payment information. Even though your card will not be charged, it will be kept on file so you can be charged if you download a for-pay item.  However, if you only plan to download free items, it may be preferable to not have your account linked to a credit card. The following steps will get you an account without entering your credit card info. Getting Started First, make sure you have iTunes installed.  If you don’t already have it, download and install it (link below) with the default settings. Now open iTunes, and click the iTunes Store link on the left. Click the App Store link on the top of this page. Select a free app to download.  A simple way to do this is to scroll down to the Top Free Apps box on the right side, hover your mouse over the first item, and click on the Free button that appears when you hover over it. A popup will open asking you to sign in with your Apple ID.  Click “Create New Account”. Click Continue to create your account. Check the box to accept the Store Terms and Conditions, and click Continue.   Enter your email address, password, security question, and date of birth, and uncheck the boxes to get email if you don’t want it…then click Continue. Now, you will be asked to provide a payment method.  Notice now that the last option says None!  Click that bullet option… Then enter your billing address.  Simply enter your normal billing address, even though you are not entering a payment method.  Click Continue and your account will be created! If you get the Address Verification screen just verify your county and click Done. An email will be sent to you to verify your account… Click on the link in your email to verify your account, iTunes will launch and you’re prompted to enter in the Apple ID and Password you just created. Your account is successfully created! Now you can easily download any free media from iTunes.  Keep an eye on the Free on iTunes box on the bottom of the iTunes Store page for interesting downloads, or if you have an iPhone or iPod Touch, watch the popular Free downloads on the Apps page. And of course there is always great content on iTunes U to grab free as well. Purchasing for-pay media If you want to purchase an item on the iTunes store later, simply click on the item to download as normal.  Click Buy to proceed with the purchase. iTunes will prompt you that you need to enter payment information to complete the purchase.  Enter your Apple ID email and password, and then add the payment information as prompted.   Remove Payment Information from an iTunes Account If you’ve already entered payment information into your iTunes account, and would like to remove it, click Store in the top iTunes menu, and select View My Account. Enter your Apple ID email and password, and click View Account.   This will open your account information.  Click the Edit Payment Information button.   Now, click the None button to remove your payment information.  Click Done to save the changes. Your account will now prompt you to enter payment information if you try to make a purchase.  You could repeat these steps after making a purchase if you do not want iTunes to keep your payment info on file. Conclusion This is a great way to make an iTunes account without entering your credit card, or to remove your credit card info from your account.  Parents may especially enjoy this tip, as they can have an iTunes account on their kids computer or iPod Touch without worrying about them spending money with it.

• How to Modify Data Security in Fusion Applications

  - by Elie Wazen

  The reference implementation in Fusion Applications is designed with built-in data security on business objects that implement the most common business practices.  For example, the “Sales Representative” job has the following two data security rules implemented on an “Opportunity” to restrict the list of Opportunities that are visible to an Sales Representative: Can view all the Opportunities where they are a member of the Opportunity Team Can view all the Opportunities where they are a resource of a territory in the Opportunity territory team While the above conditions may represent the most common access requirements of an Opportunity, some customers may have additional access constraints. This blog post explains: How to discover the data security implemented in Fusion Applications. How to customize data security Illustrative example. a.) How to discover seeded data security definitions The Security Reference Manuals explain the Function and Data Security implemented on each job role.  Security Reference Manuals are available on Oracle Enterprise Repository for Oracle Fusion Applications. The following is a snap shot of the security documented for the “Sales Representative” Job. The two data security policies define the list of Opportunities a Sales Representative can view. Here is a sample of data security policies on an Opportunity. Business Object Policy Description Policy Store Implementation Opportunity A Sales Representative can view opportunity where they are a territory resource in the opportunity territory team Role: Opportunity Territory Resource Duty Privilege: View Opportunity (Data) Resource: Opportunity A Sales Representative can view opportunity where they are an opportunity sales team member with view, edit, or full access Role: Opportunity Sales Representative Duty Privilege: View Opportunity (Data) Resource: Opportunity Description of Columns Column Name Description Policy Description Explains the data filters that are implemented as a SQL Where Clause in a Data Security Grant Policy Store Implementation Provides the implementation details of the Data Security Grant for this policy. In this example the Opportunities listed for a “Sales Representative” job role are derived from a combination of two grants defined on two separate duty roles at are inherited by the Sales Representative job role. b.) How to customize data security Requirement 1: Opportunities should be viewed only by members of the opportunity team and not by all the members of all the territories on the opportunity. Solution: Remove the role “Opportunity Territory Resource Duty” from the hierarchy of the “Sales Representative” job role. Best Practice: Do not modify the seeded role hierarchy. Create a custom “Sales Representative” job role and build the role hierarchy with the seeded duty roles. Requirement 2: Opportunities must be more restrictive based on a custom attribute that identifies if a Opportunity is confidential or not. Confidential Opportunities must be visible only the owner of the Opportunity. Solution: Modify the (2) data security policy in the above example as follows: A Sales Representative can view opportunity where they are a territory resource in the opportunity territory team and the opportunity is not confidential. Implementation of this policy is more invasive. The seeded SQL where clause of the data security grant on “Opportunity Territory Resource Duty” has to be modified and the condition that checks for the confidential flag must be added. Best Practice: Do not modify the seeded grant. Create a new grant with the modified condition. End Date the seeded grant. c.) Illustrative Example (Implementing Requirement 2) A data security policy contains the following components: Role Object Instance Set Action Of the above four components, the Role and Instance Set are the only components that are customizable. Object and Actions for that object are seed data and cannot be modified. To customize a seeded policy, “A Sales Representative can view opportunity where they are a territory resource in the opportunity territory team”, Find the seeded policy Identify the Role, Object, Instance Set and Action components of the policy Create a new custom instance set based on the seeded instance set. End Date the seeded policies Create a new data security policy with custom instance set c-1: Find the seeded policy Step 1: 1. Find the Role 2. Open 3. Find Policies Step 2: Click on the Data Security Tab Sort by “Resource Name” Find all the policies with the “Condition” as “where they are a territory resource in the opportunity territory team” In this example, we can see there are 5 policies for “Opportunity Territory Resource Duty” on Opportunity object. Step 3: Now that we know the policy details, we need to create new instance set with the custom condition. All instance sets are linked to the object. Find the object using global search option. Open it and click on “condition” tab Sort by Display name Find the Instance set Edit the instance set and copy the “SQL Predicate” to a notepad. Create a new instance set with the modified SQL Predicate from above by clicking on the icon as shown below. Step 4: End date the seeded data security policies on the duty role and create new policies with your custom instance set. Repeat the navigation in step Edit each of the 5 policies and end date them 3. Create new custom policies with the same information as the seeded policies in the “General Information”, “Roles” and “Action” tabs. 4. In the “Rules” tab, please pick the new instance set that was created in Step 3.

• Forcing an External Activation with Service Broker

  - by Davide Mauri

  In these last days I’ve been working quite a lot with Service Broker, a technology I’m really happy to work with, since it can give a lot of satisfaction. The scale-out solution one can easily build is simply astonishing. I’m helping a company to build a very scalable and – yet almost inexpensive – invoicing system that has to be able to scale out using commodity hardware. To offload the work from the main server to satellite “compute nodes” (yes, I’ve borrowed this term from PDW) we’re using Service Broker and the External Activator application available in the SQL Server Feature Pack. For those who are not used to work with SSB, the External Activation is a feature that allows you to intercept the arrival of a message in a queue right from your application code. http://msdn.microsoft.com/en-us/library/ms171617.aspx (Look for “Event-Based Activation”) In order to make life even more easier, Microsoft released the External Activation application that saves you even from writing even this code. http://blogs.msdn.com/b/sql_service_broker/archive/tags/external+activator/ The External Activator application can be configured to execute your own application so that each time a message – an invoice in my case – arrives in the target queue, the invoking application is executed and the invoice is calculated. The very nice feature of External Activator is that it can automatically execute as many configured application in order to process as many messages as your system can handle.  This also a lot of create a scale-out solution, leaving to the developer only a fraction of the problems that usually came with asynchronous programming. Developers are also shielded from Service Broker since everything can be encapsulated in Stored Procedures, so that – for them – developing such scale-out asynchronous solution is not much more complex than just executing a bunch of Stored Procedures. Now, if everything works correctly, you don’t have to bother of anything else. You put messages in the queue and your application, invoked by the External Activator, process them. But what happen if for some reason your application fails to process the messages. For examples, it crashes? The message is safe in the queue so you just need to process it again. But your application is invoked by the External Activator application, so now the question is, how do you wake up that app? Service Broker will engage the activation process only if certain conditions are met: http://msdn.microsoft.com/en-us/library/ms171601.aspx But how we can invoke the activation process manually, without having to wait for another message to arrive (the arrival of a new message is a condition that can fire the activation process)? The “trick” is to do manually with the activation process does: sending a system message to a queue in charge of handling External Activation messages: declare @conversationHandle uniqueidentifier; declare @n xml = N' <EVENT_INSTANCE>   <EventType>QUEUE_ACTIVATION</EventType>   <PostTime>' + CONVERT(CHAR(24),GETDATE(),126) + '</PostTime>   <SPID>' + CAST(@@SPID AS VARCHAR(9)) + '</SPID>   <ServerName>[your_server_name]</ServerName>   <LoginName>[your_login_name]</LoginName>   <UserName>[your_user_name]</UserName>   <DatabaseName>[your_database_name]</DatabaseName>   <SchemaName>[your_queue_schema_name]</SchemaName>   <ObjectName>[your_queue_name]</ObjectName>   <ObjectType>QUEUE</ObjectType> </EVENT_INSTANCE>' begin dialog conversation     @conversationHandle from service        [<your_initiator_service_name>] to service          '<your_event_notification_service>' on contract         [http://schemas.microsoft.com/SQL/Notifications/PostEventNotification] with     encryption = off,     lifetime = 6000 ; send on conversation     @conversationHandle message type     [http://schemas.microsoft.com/SQL/Notifications/EventNotification] (@n) ;     end conversation @conversationHandle; That’s it! Put the code in a Stored Procedure and you can add to your application a button that says “Force Queue Processing” (or something similar) in order to start the activation process whenever you need it (which should not occur too frequently but it may happen). PS I know that the “fire-and-forget” (ending the conversation without waiting for an answer) technique is not a best practice, but in this case I don’t see how it can hurts so I decided to stay very close to the KISS principle []

• SQL SERVER – PAGEIOLATCH_DT, PAGEIOLATCH_EX, PAGEIOLATCH_KP, PAGEIOLATCH_SH, PAGEIOLATCH_UP – Wait Type – Day 9 of 28

  - by pinaldave

  It is very easy to say that you replace your hardware as that is not up to the mark. In reality, it is very difficult to implement. It is really hard to convince an infrastructure team to change any hardware because they are not performing at their best. I had a nightmare related to this issue in a deal with an infrastructure team as I suggested that they replace their faulty hardware. This is because they were initially not accepting the fact that it is the fault of their hardware. But it is really easy to say “Trust me, I am correct”, while it is equally important that you put some logical reasoning along with this statement. PAGEIOLATCH_XX is such a kind of those wait stats that we would directly like to blame on the underlying subsystem. Of course, most of the time, it is correct – the underlying subsystem is usually the problem. From Book On-Line: PAGEIOLATCH_DT Occurs when a task is waiting on a latch for a buffer that is in an I/O request. The latch request is in Destroy mode. Long waits may indicate problems with the disk subsystem. PAGEIOLATCH_EX Occurs when a task is waiting on a latch for a buffer that is in an I/O request. The latch request is in Exclusive mode. Long waits may indicate problems with the disk subsystem. PAGEIOLATCH_KP Occurs when a task is waiting on a latch for a buffer that is in an I/O request. The latch request is in Keep mode. Long waits may indicate problems with the disk subsystem. PAGEIOLATCH_SH Occurs when a task is waiting on a latch for a buffer that is in an I/O request. The latch request is in Shared mode. Long waits may indicate problems with the disk subsystem. PAGEIOLATCH_UP Occurs when a task is waiting on a latch for a buffer that is in an I/O request. The latch request is in Update mode. Long waits may indicate problems with the disk subsystem. PAGEIOLATCH_XX Explanation: Simply put, this particular wait type occurs when any of the tasks is waiting for data from the disk to move to the buffer cache. ReducingPAGEIOLATCH_XX wait: Just like any other wait type, this is again a very challenging and interesting subject to resolve. Here are a few things you can experiment on: Improve your IO subsystem speed (read the first paragraph of this article, if you have not read it, I repeat that it is easy to say a step like this than to actually implement or do it). This type of wait stats can also happen due to memory pressure or any other memory issues. Putting aside the issue of a faulty IO subsystem, this wait type warrants proper analysis of the memory counters. If due to any reasons, the memory is not optimal and unable to receive the IO data. This situation can create this kind of wait type. Proper placing of files is very important. We should check file system for the proper placement of files – LDF and MDF on separate drive, TempDB on separate drive, hot spot tables on separate filegroup (and on separate disk), etc. Check the File Statistics and see if there is higher IO Read and IO Write Stall SQL SERVER – Get File Statistics Using fn_virtualfilestats. It is very possible that there are no proper indexes on the system and there are lots of table scans and heap scans. Creating proper index can reduce the IO bandwidth considerably. If SQL Server can use appropriate cover index instead of clustered index, it can significantly reduce lots of CPU, Memory and IO (considering cover index has much lesser columns than cluster table and all other it depends conditions). You can refer to the two articles’ links below previously written by me that talk about how to optimize indexes. Create Missing Indexes Drop Unused Indexes Updating statistics can help the Query Optimizer to render optimal plan, which can only be either directly or indirectly. I have seen that updating statistics with full scan (again, if your database is huge and you cannot do this – never mind!) can provide optimal information to SQL Server optimizer leading to efficient plan. Checking Memory Related Perfmon Counters SQLServer: Memory Manager\Memory Grants Pending (Consistent higher value than 0-2) SQLServer: Memory Manager\Memory Grants Outstanding (Consistent higher value, Benchmark) SQLServer: Buffer Manager\Buffer Hit Cache Ratio (Higher is better, greater than 90% for usually smooth running system) SQLServer: Buffer Manager\Page Life Expectancy (Consistent lower value than 300 seconds) Memory: Available Mbytes (Information only) Memory: Page Faults/sec (Benchmark only) Memory: Pages/sec (Benchmark only) Checking Disk Related Perfmon Counters Average Disk sec/Read (Consistent higher value than 4-8 millisecond is not good) Average Disk sec/Write (Consistent higher value than 4-8 millisecond is not good) Average Disk Read/Write Queue Length (Consistent higher value than benchmark is not good) Note: The information presented here is from my experience and there is no way that I claim it to be accurate. I suggest reading Book OnLine for further clarification. All of the discussions of Wait Stats in this blog is generic and varies from system to system. It is recommended that you test this on a development server before implementing it to a production server.

• Integrate BING API for Search inside ASP.Net web application

  - by sreejukg

  As you might already know, Bing is the Microsoft Search engine and is getting popular day by day. Bing offers APIs that can be integrated into your website to increase your website functionality. At this moment, there are two important APIs available. They are Bing Search API Bing Maps The Search API enables you to build applications that utilize Bing’s technology. The API allows you to search multiple source types such as web; images, video etc. and supports various output prototypes such as JSON, XML, and SOAP. Also you will be able to customize the search results as you wish for your public facing website. Bing Maps API allows you to build robust applications that use Bing Maps. In this article I am going to describe, how you can integrate Bing search into your website. In order to start using Bing, First you need to sign in to http://www.bing.com/toolbox/bingdeveloper/ using your windows live credentials. Click on the Sign in button, you will be asked to enter your windows live credentials. Once signed in you will be redirected to the Developer page. Here you can create applications and get AppID for each application. Since I am a first time user, I don’t have any applications added. Click on the Add button to add a new application. You will be asked to enter certain details about your application. The fields are straight forward, only thing you need to note is the website field, here you need to enter the website address from where you are going to use this application, and this field is optional too. Of course you need to agree on the terms and conditions and then click Save. Once you click on save, the application will be created and application ID will be available for your use. Now we got the APP Id. Basically Bing supports three protocols. They are JSON, XML and SOAP. JSON is useful if you want to call the search requests directly from the browser and use JavaScript to parse the results, thus JSON is the favorite choice for AJAX application. XML is the alternative for applications that does not support SOAP, e.g. flash/ Silverlight etc. SOAP is ideal for strongly typed languages and gives a request/response object model. In this article I am going to demonstrate how to search BING API using SOAP protocol from an ASP.Net application. For the purpose of this demonstration, I am going to create an ASP.Net project and implement the search functionality in an aspx page. Open Visual Studio, navigate to File-> New Project, select ASP.Net empty web application, I named the project as “BingSearchSample”. Add a Search.aspx page to the project, once added the solution explorer will looks similar to the following. Now you need to add a web reference to the SOAP service available from Bing. To do this, from the solution explorer, right click your project, select Add Service Reference. Now the new service reference dialog will appear. In the left bottom of the dialog, you can find advanced button, click on it. Now the service reference settings dialog will appear. In the bottom left, you can find Add Web Reference button, click on it. The add web reference dialog will appear now. Enter the URL as http://api.bing.net/search.wsdl?AppID=<YourAppIDHere>&version=2.2 (replace <yourAppIDHere> with the appID you have generated previously) and click on the button next to it. This will find the web service methods available. You can change the namespace suggested by Bing, but for the purpose of this demonstration I have accepted all the default settings. Click on the Add reference button once you are done. Now the web reference to Search service will be added your project. You can find this under solution explorer of your project. Now in the Search.aspx, that you previously created, place one textbox, button and a grid view. For the purpose of this demonstration, I have given the identifiers (ID) as txtSearch, btnSearch, gvSearch respectively. The idea is to search the text entered in the text box using Bing service and show the results in the grid view. In the design view, the search.aspx looks as follows. In the search.aspx.cs page, add a using statement that points to net.bing.api. I have added the following code for button click event handler. The code is very straight forward. It just calls the service with your AppID, a query to search and a source for searching. Let us run this page and see the output when I enter Microsoft in my textbox. If you want to search a specific site, you can include the site name in the query parameter. For e.g. the following query will search the word Microsoft from www.microsoft.com website. searchRequest.Query = “site:www.microsoft.com Microsoft”; The output of this query is as follows. Integrating BING search API to your website is easy and there is no limit on the customization of the interface you can do. There is no Bing branding required so I believe this is a great option for web developers when they plan for site search.

• Test-Drive ASP.NET MVC Review

  - by Ben Griswold

  A few years back I started dallying with test-driven development, but I never fully committed to the practice. This wasn’t because I didn’t believe in the value of TDD; it was more a matter of not completely understanding how to incorporate “test first” into my everyday development. Back in my web forms days, I could point fingers at the framework for my ignorance and laziness. After all, web forms weren’t exactly designed for testability so who could blame me for not embracing TDD in those conditions, right? But when I switched to ASP.NET MVC and quickly found myself fresh out of excuses and it became instantly clear that it was time to get my head around red-green-refactor once and for all or I would regretfully miss out on one of the biggest selling points the new framework had to offer. I have previously written about how I learned ASP.NET MVC. It was primarily hands on learning but I did read a couple of ASP.NET MVC books along the way. The books I read dedicated a chapter or two to TDD and they certainly addressed the benefits of TDD and how MVC was designed with testability in mind, but TDD was merely an afterthought compared to, well, teaching one how to code the model, view and controller. This approach made some sense, and I learned a bunch about MVC from those books, but when it came to TDD the books were just a teaser and an opportunity missed.  But then I got lucky – Jonathan McCracken contacted me and asked if I’d review his book, Test-Drive ASP.NET MVC, and it was just what I needed to get over the TDD hump. As the title suggests, Test-Drive ASP.NET MVC takes a different approach to learning MVC as it focuses on testing right from the very start. McCracken wastes no time and swiftly familiarizes us with the framework by building out a trivial Quote-O-Matic application and then dedicates the better part of his book to testing first – first by explaining TDD and then coding a full-featured Getting Organized application inspired by David Allen’s popular book, Getting Things Done. If you are a learn-by-example kind of coder (like me), you will instantly appreciate and enjoy McCracken’s style – its fast-moving, pragmatic and focused on only the most relevant information required to get you going with ASP.NET MVC and TDD. The book continues with the test-first theme but McCracken moves away from the sample application and incorporates other practical skills like persisting models with NHibernate, leveraging Inversion of Control with the IControllerFactory and building a RESTful web service. What I most appreciated about this section was McCracken’s use of and praise for open source libraries like Rhino Mocks, SQLite and StructureMap (to name just a few) and productivity tools like ReSharper, Web Platform Installer and ASP.NET SQL Server Setup Wizard.  McCracken’s emphasis on real world, pragmatic development was clearly demonstrated in every tool choice, straight-forward code block and developer tip. Whether one is already familiar with the tools/tips or not, McCracken’s thought process is easily understood and appreciated. The final section of the book walks the reader through security and deployment – everything from error handling and logging with ELMAH, to ASP.NET Health Monitoring, to using MSBuild with automated builds, to the deployment  of ASP.NET MVC to various web environments. These chapters, like those prior, offer enough information and explanation to simply help you get the job done.  Do I believe Test-Drive ASP.NET MVC will turn you into an expert MVC developer overnight?  Well, no.  I don’t think any book can make that claim.  If that were possible, I think book list prices would skyrocket!  That said, Test-Drive ASP.NET MVC provides a solid foundation and a unique (and dare I say necessary) approach to learning ASP.NET MVC.  Along the way McCracken shares loads of very practical software development tips and references numerous tools and libraries. The bottom line is it’s a great ASP.NET MVC primer – if you’re new to ASP.NET MVC it’s just what you need to get started.  Do I believe Test-Drive ASP.NET MVC will give you everything you need to start employing TDD in your everyday development?  Well, I used to think that learning TDD required a lot of practice and, if you’re lucky enough, the guidance of a mentor or coach.  I used to think that one couldn’t learn TDD from a book alone. Well, I’m still no pro, but I’m testing first now and Jonathan McCracken and his book, Test-Drive ASP.NET MVC, played a big part in making this happen.  If you are an MVC developer and a TDD newb, Test-Drive ASP.NET MVC is just the book for you.

• Installing SharePoint 2013 on Windows 2012- standalone installation

  - by sreejukg

  In this article, I am going to share my experience while installing SharePoint 2013 on Windows 2012. This was the first time I tried SharePoint 2013. So I thought sharing the same will benefit somebody who would like to install SharePoint 2013 as a standalone installation. Standalone installation is meant for evaluation/development purposes. For production environments, you need to follow the best practices and create required service accounts. Microsoft has published the deployment guide for SharePoint 2013, you can download this from the below link. http://www.microsoft.com/en-us/download/details.aspx?id=30384 Since this is for development environment, I am not going to create any service account, I logged in to Windows 2012 as an administrator and just placed my installation DVD on the drive. When I run the setup from the DVD, the below splash screen appears. This reflects the new UI changes happening with all Microsoft based applications; the interface matches the metro style applications (Windows 8 style). As you can see the options are same as that of the SharePoint 2010 installation screen. Click on the “install software prerequisites” link to get all the prerequisites get installed. You need a valid internet connection to do this. Clicking on the install software prerequisites will bring the following dialog. Click Next, you will see the terms and conditions. Select I accept check box and click Next. The installation will start immediately. For any reason, if you stop the installation and start it later, the product preparation tool will check whether a particular component is installed and if yes, then the installation of that particular component will be skipped. If you do not have internet connection, you will face the download error as follows. At any point of failure, the error log will be available for you to review. If all OK, you will reach the below dialog, this means some components will be installed once the PC is rebooted. Be noted that the clicking on finish will not ask you for further confirmation. So make sure to save all your work before clicking on finish button. Once the server is restarted, the product preparation tool will start automatically and you will see the following dialog. Now go to the SharePoint 2013 splash page and click on “Install SharePoint Server” link. You need to enter the product key here. Enter the product key as you received and click continue. Select the Checkbox for the license agreement and click on continue button. Now you need to select the installation type. Select Stand-alone and click on “Install Now” button. A dialog will pop up that updates you with the process and progress. The installation took around 15-20 minutes with 2 GB or Ram installed in the server, seems fair. Once the installation is over, you will see the following Dialog. Make sure you select the Run the products and configuration wizard. If you miss to select the check box, you can find the products and configuration wizard from the start tiles. The products and configuration wizard will start. If you get any dialog saying some of the services will be stopped, you just accept it. Since we selected standalone installation, it will not ask for any user input, as it already knows the database to be configured. Once the configuration is over without any problems you will see the configuration successful message. Also you can find the link to central administration on the Start Screen.     Troubleshooting During my first setup process, I got the below error. System.ArgumentException: The SDDL string contains an invalid sid or a sid that cannot be translated. Parameter name: sddlForm at System.Security.AccessControl.RawSecurityDescriptor.BinaryFormFromSddlForm(String sddlForm) at System.Security.AccessControl.RawSecurityDescriptor..ctor(String sddlForm) at Microsoft.SharePoint.Win32.SPNetApi32.CreateShareSecurityDescriptor(String[] readNames, String[] changeNames, String[] fullControlNames, String& sddl) at Microsoft.SharePoint.Win32.SPNetApi32.CreateFileShare(String name, String description, String path) at Microsoft.SharePoint.Administration.SPServer.CreateFileShare(String name, String description, String path) at Microsoft.Office.Server.Search.Administration.AnalyticsAdministration.CreateAnalyticsUNCShare(String dirParentLocation, String shareName) at Microsoft.Office.Server.Search.Administration.AnalyticsAdministration.ProvisionAnalyticsShare(SearchServiceApplication serviceApplication) ………………………………………… ………………………………………… The configuration wizard displayed the error as below. The error occurred in step 8 of the configuration wizard and by the time the central administration is already provisioned. So from the start, I was able to open the central administration website, but the search service application was showing as error. I found a good blog that specifies the reason for error. http://kbdump.com/sharepoint2013-standalone-config-error-create-sample-data/ The workaround specified in the blog works fine. I think SharePoint must be provisioning Search using the Network Service account, so instead of giving permission to everyone, you could try giving permission to Network Service account(I didn’t try this yet, buy you could try and post your feedback here). In production environment you will have specific accounts that have access rights as recommended by Microsoft guidelines. Installation of SharePoint 2013 is pretty straight forward. Hope you enjoyed the article!

• An Alphabet of Eponymous Aphorisms, Programming Paradigms, Software Sayings, Annoying Alliteration

  - by Brian Schroer

  Malcolm Anderson blogged about “Einstein’s Razor” yesterday, which reminded me of my favorite software development “law”, the name of which I can never remember. It took much Wikipedia-ing to find it (Hofstadter’s Law – see below), but along the way I compiled the following list: Amara’s Law: We tend to overestimate the effect of a technology in the short run and underestimate the effect in the long run. Brook’s Law: Adding manpower to a late software project makes it later. Clarke’s Third Law: Any sufficiently advanced technology is indistinguishable from magic. Law of Demeter: Each unit should only talk to its friends; don't talk to strangers. Einstein’s Razor: “Make things as simple as possible, but not simpler” is the popular paraphrase, but what he actually said was “It can scarcely be denied that the supreme goal of all theory is to make the irreducible basic elements as simple and as few as possible without having to surrender the adequate representation of a single datum of experience”, an overly complicated quote which is an obvious violation of Einstein’s Razor. (You can tell by looking at a picture of Einstein that the dude was hardly an expert on razors or other grooming apparati.) Finagle's Law of Dynamic Negatives: Anything that can go wrong, will—at the worst possible moment. - O'Toole's Corollary: The perversity of the Universe tends towards a maximum. Greenspun's Tenth Rule: Any sufficiently complicated C or Fortran program contains an ad hoc, informally-specified, bug-ridden, slow implementation of half of Common Lisp. (Morris’s Corollary: “…including Common Lisp”) Hofstadter's Law: It always takes longer than you expect, even when you take into account Hofstadter's Law. Issawi’s Omelet Analogy: One cannot make an omelet without breaking eggs - but it is amazing how many eggs one can break without making a decent omelet. Jackson’s Rules of Optimization: Rule 1: Don't do it. Rule 2 (for experts only): Don't do it yet. Kaner’s Caveat: A program which perfectly meets a lousy specification is a lousy program. Liskov Substitution Principle (paraphrased): Functions that use pointers or references to base classes must be able to use objects of derived classes without knowing it Mason’s Maxim: Since human beings themselves are not fully debugged yet, there will be bugs in your code no matter what you do. Nils-Peter Nelson’s Nil I/O Rule: The fastest I/O is no I/O.    Occam's Razor: The simplest explanation is usually the correct one. Parkinson’s Law: Work expands so as to fill the time available for its completion. Quentin Tarantino’s Pie Principle: “…you want to go home have a drink and go and eat pie and talk about it.” (OK, he was talking about movies, not software, but I couldn’t find a “Q” quote about software. And wouldn’t it be cool to write a program so great that the users want to eat pie and talk about it?) Raymond’s Rule: Computer science education cannot make anybody an expert programmer any more than studying brushes and pigment can make somebody an expert painter.  Sowa's Law of Standards: Whenever a major organization develops a new system as an official standard for X, the primary result is the widespread adoption of some simpler system as a de facto standard for X. Turing’s Tenet: We shall do a much better programming job, provided we approach the task with a full appreciation of its tremendous difficulty, provided that we respect the intrinsic limitations of the human mind and approach the task as very humble programmers.  Udi Dahan’s Race Condition Rule: If you think you have a race condition, you don’t understand the domain well enough. These rules didn’t exist in the age of paper, there is no reason for them to exist in the age of computers. When you have race conditions, go back to the business and find out actual rules. Van Vleck’s Kvetching: We know about as much about software quality problems as they knew about the Black Plague in the 1600s. We've seen the victims' agonies and helped burn the corpses. We don't know what causes it; we don't really know if there is only one disease. We just suffer -- and keep pouring our sewage into our water supply. Wheeler’s Law: All problems in computer science can be solved by another level of indirection... Except for the problem of too many layers of indirection. Wheeler also said “Compatibility means deliberately repeating other people's mistakes.”. The Wrong Road Rule of Mr. X (anonymous): No matter how far down the wrong road you've gone, turn back. Yourdon’s Rule of Two Feet: If you think your management doesn't know what it's doing or that your organisation turns out low-quality software crap that embarrasses you, then leave. Zawinski's Law of Software Envelopment: Every program attempts to expand until it can read mail. Zawinski is also responsible for “Some people, when confronted with a problem, think 'I know, I'll use regular expressions.' Now they have two problems.” He once commented about X Windows widget toolkits: “Using these toolkits is like trying to make a bookshelf out of mashed potatoes.”

• Integrate Microsoft Translator into your ASP.Net application

  - by sreejukg

  In this article I am going to explain how easily you can integrate the Microsoft translator API to your ASP.Net application. Why we need a translation API? Once you published a website, you are opening a channel to the global audience. So making the web content available only in one language doesn’t cover all your audience. Especially when you are offering products/services it is important to provide contents in multiple languages. Users will be more comfortable when they see the content in their native language. How to achieve this, hiring translators and translate the content to all your user’s languages will cost you lot of money, and it is not a one time job, you need to translate the contents on the go. What is the alternative, we need to look for machine translation. Thankfully there are some translator engines available that gives you API level access, so that automatically you can translate the content and display to the user. Microsoft Translator API is an excellent set of web service APIs that allows developers to use the machine translation technology in their own applications. The Microsoft Translator API is offered through Windows Azure market place. In order to access the data services published in Windows Azure market place, you need to have an account. The registration process is simple, and it is common for all the services offered through the market place. Last year I had written an article about Bing Search API, where I covered the registration process. You can refer the article here. http://weblogs.asp.net/sreejukg/archive/2012/07/04/integrate-bing-search-api-to-asp-net-application.aspx Once you registered with Windows market place, you will get your APP ID. Now you can visit the Microsoft Translator page and click on the sign up button. http://datamarket.azure.com/dataset/bing/microsofttranslator As you can see, there are several options available for you to subscribe. There is a free version available, great. Click on the sign up button under the package that suits you. Clicking on the sign up button will bring the sign up form, where you need to agree on the terms and conditions and go ahead. You need to have a windows live account in order to sign up for any service available in Windows Azure market place. Once you signed up successfully, you will receive the thank you page. You can download the C# class library from here so that the integration can be made without writing much code. The C# file name is TranslatorContainer.cs. At any point of time, you can visit https://datamarket.azure.com/account/datasets to see the applications you are subscribed to. Click on the Use link next to each service will give you the details of the application. You need to not the primary account key and URL of the service to use in your application. Now let us start our ASP.Net project. I have created an empty ASP.Net web application using Visual Studio 2010 and named it Translator Sample, any name could work. By default, the web application in solution explorer looks as follows. Now right click the project and select Add -> Existing Item and then browse to the TranslatorContainer.cs. Now let us create a page where user enter some data and perform the translation. I have added a new web form to the project with name Translate.aspx. I have placed one textbox control for user to type the text to translate, the dropdown list to select the target language, a label to display the translated text and a button to perform the translation. For the dropdown list I have selected some languages supported by Microsoft translator. You can get all the supported languages with their codes from the below link. http://msdn.microsoft.com/en-us/library/hh456380.aspx The form looks as below in the design surface of Visual Studio. All the class libraries in the windows market place requires reference to System.Data.Services.Client, let us add the reference. You can find the documentation of how to use the downloaded class library from the below link. http://msdn.microsoft.com/en-us/library/gg312154.aspx Let us evaluate the translatorContainer.cs file. You can refer the code and it is self-explanatory. Note the namespace name used (Microsoft), you need to add the namespace reference to your page. I have added the following event for the translate button. The code is self-explanatory. You are creating an object of TranslatorContainer class by passing the translation service URL. Now you need to set credentials for your Translator container object, which will be your account key. The TranslatorContainer support a method that accept a text input, source language and destination language and returns DataServiceQuery<Translation>. Let us see this working, I just ran the application and entered Good Morning in the Textbox. Selected target language and see the output as follows. It is easy to build great translator applications using Microsoft translator API, and there is a reasonable amount of translation you can perform in your application for free. For enterprises, you can subscribe to the appropriate package and make your application multi-lingual.
