• Windows Media Player 11 fails to authenticate with proxy (ISA)

  - by Ed Manet

  We have some users who need to use a 3rd party site that embeds Windows Media Player streaming video into a web page. Our users go through an ISA proxy server to connect to the Internet. The browser has no problems accessing the site through the proxy. When Media Player loads, we get prompted for network credentials, but the authentication fails. If we set up Internet Explorer 8 to not use the proxy, Media Player has no problem. Media Player is configured to use the RTSP/TCP and HTTP protocols, but not the RTSP/UDP protocol. Is this necessary? Is there a registry key I can use to enable it? Is this more of a proxy server issue? The proxy guy says it's a desktop issue.

• Should I host my entire web application using https?

  - by user54455

  Actually my only requirement for using SSL encryption is that when a user logs in, the password is transferred encrypted. However after reading a bit about protocol switching, that an HTTPS session can't be taken over as an HTTP session etc. I've been asking myself if it's so bad to just have the entire application use HTTPS only. What are the reasons against it and how would you rate their importance? Please also mention: How much performance do I lose on server side (roughly)? How much performance do I lose on client side (roughly)? Any other problems on server / client side?

• Other options to "balance source" in haproxy

  - by PriceChild

  I have haproxy listening on several ports and pointed at several backend servers. Ideally, I would like it so that repeated communications to the same port get pointed at the same backend. "balance source" isn't workable because often requests come from the same source. Is this doable? I'm also open to non-haproxy solutions. The protocol being used isn't important but is definitely not http. Just assume its ssh and you shouldn't go wrong.

• ssh accepts any password

  - by nodapic

  I'm recovering a server from getting hacked and there is one thing I can't fix: When I ssh (or scp) to the server, no matter what password I give, it lets me log in. I don't know much about the ssh protocol but I'm pretty sure it's not supposed to do that. I've checked in the sshd_config file and the only changes are the ones that I've made (as far as I can remember). Another thought that I had was that there might be something screwed up in the /etc/passwd file that I'm missing. Has anyone seen this?

• How can I push a git repository to a folder over SSH?

  - by Rich

  I have a folder called my-project inside which I've done git init, git commit -a, etc. Now I want to push it to an empty folder at /mnt/foo/bar on a remote server. How can I do this? I did try, based on what I'd read: cd my-project git remote add origin ssh://user@host/mnt/foo/bar/my-project.git git push origin master which didn't seem right (I'd assume source would come before destination) and it failed: fatal: '/mnt/boxee/git/midwinter-physiotherapy.git' does not appear to be a git repository fatal: The remote end hung up unexpectedly I'd like this to work such that I don't have to access the remote host and manually init a git repository every time ... do I have to do that? Am I going down the right route at all? Thanks.

• svn:externals cache and stale URLs

  - by dcaunt

  I have a subversion externals entry in a library folder which looks like this: Z https://svn/Z/trunk/library/Z Fetching external item into '/home/releases/50/library/Z' svn: OPTIONS of 'http://svn/repo/trunk/library/Z': could not connect to server (http://svn) The externals URL was the same, but over the HTTP protocol. Having changed the externals to point to the HTTPS, I can't figure out why subversion is still trying to use the old URL. Does subversion cache the externals path, and if so how can I clear this? If not, what else could be causing this? I can check out from the correct (HTTPS) URL fine from the server. NOTE: svn is an entry in the server's local hosts file, pointing to our subversion server's IP.

• Can I use Server Monitor with a non-server Mac?

  - by Chris

  I have a computer I use as a simple file and web server. I am simply desiring to be able to monitor load, traffic, memory usage, etc via Server Monitor. I have also downloaded an app for my iPhone which does the same thing, but it uses the same protocol that Server Monitor does. Is it possible to get Server Monitor to recognize my non-server box as a server so I can monitor this information? For reference, I am running 10.4.11 on this PPC box. Thanks in advance!

• Is there a good way to prevent a server from emailing a specific address (we control both servers/apps)?

  - by Bms85smb

  When testing a production app we occasionally need to pull from a live site and perform tests on a development server. There are quite a few email addresses stored in the database that we need to modify every time we restore to the development server. Occasionally someone on my team will miss one and accidentally send an email through the distribution list. The email looks legit because it is coming from a clone, it can cause quite the situation. We have a protocol we follow every time we clone the live app and it has helped a lot but I would feel better if it was impossible for the two servers to communicate. Is there a good way to do this? Can firewall rules block email? Does Plesk have a blacklist?

• Delphi Speech recognition delphi

  - by XBasic3000

  I need create a programatic equivalent using delphi language... or could someone post a link on how to do grammars in peech recogniton using the delphi. sorry for my english... XML Grammar Sample(s): <GRAMMAR> <!-- Create a simple "hello world" rule --> <RULE NAME="HelloWorld" TOPLEVEL="ACTIVE"> <P>hello world</P> </RULE> <!-- Create a more advanced "hello world" rule that changes the display form. When the user says "hello world" the display text will be "Hiya there!" --> <RULE NAME="HelloWorld_Disp" TOPLEVEL="ACTIVE"> <P DISP="Hiya there!">hello world</P> </RULE> <!-- Create a rule that changes the pronunciation and the display form of the phrase. When the user says "eh" the display text will be "I don't understand?". Note the user didn't say "huh". The pronunciation for "what" is specific to this phrase tag and is not changed for the user or application lexicon, or even other instances of "what" in the grammar --> <RULE NAME="Question_Pron" TOPLEVEL="ACTIVE"> <P DISP="I don't understand" PRON="eh">what</P> </RULE> <!-- Create a rule demonstrating repetition --> <!-- the rule will only be recognized if the user says "hey diddle diddle" --> <RULE NAME="NurseryRhyme" TOPLEVEL="ACTIVE"> <P>hey</P> <P MIN="2" MAX="2">diddle</P> </RULE> <!-- Create a list with variable phrase weights --> <!-- If the user says similar phrases, the recognizer will use the weights to pick a match --> <RULE NAME="UseWeights" TOPLEVEL="ACTIVE"> <LIST> <!-- Note the higher likelihood that the user is expected to say "recognizer speech" --> <P WEIGHT=".95">recognize speech</P> <P WEIGHT=".05">wreck a nice beach</P> </LIST> </RULE> <!-- Create a phrase with an attached semantic property --> <!-- Speaking "one two three" will return three different unique semantic properties, with different names, and different values --> <RULE NAME="UseProps" TOPLEVEL="ACTIVE"> <!-- named property, without value --> <P PROPNAME="NOVALUE">one</P> <!-- named property, with numeric value --> <P PROPNAME="NUMBER" VAL="2">two</P> <!-- named property, with string value --> <P PROPNAME="STRING" VALSTR="three">three</P> </RULE> </GRAMMAR> **Programmatic Equivalent:** To add a phrase to a rule, SAPI provides an API called ISpGrammarBuilder::AddWordTransition. The application developer can add the sentences as follows: SPSTATEHANDLE hsHelloWorld; // Create new top-level rule called "HelloWorld" hr = cpRecoGrammar->GetRule(L"HelloWorld", NULL, SPRAF_TopLevel | SPRAF_Active, TRUE, &hsHelloWorld); // Check hr // Add the command words "hello world" // Note that the lexical delimiter is " ", a space character. // By using a space delimiter, the entire phrase can be added // in one method call hr = cpRecoGrammar->AddWordTransition(hsHelloWorld, NULL, L"hello world", L" ", SPWT_LEXICAL, NULL, NULL); // Check hr // Add the command words "hiya there" // Note that the lexical delimiter is "|", a pipe character. // By using a pipe delimiter, the entire phrase can be added // in one method call hr = cpRecoGrammar->AddWordTransition(hsHelloWorld, NULL, L"hiya|there", L"|", SPWT_LEXICAL, NULL, NULL); // Check hr // save/commit changes hr = cpRecoGrammar->Commit(NULL); // Check hr

• Installshield Development Error durring the Installation process

  - by Alopekos

  Hey guys, I've been stuck by a problem for the past couple days that makes no sense to me. My installer builds fine in the Installshiled IDE but when it is about to finish the installation, int gets two errors then rollbacks: installation failure. Right when the install bar is at about 100%, an error box pops up that states this: "Error 1001.Exception occurred while initializing the installation: System.IO.FileLoadException: Attempt to load an unverifiable executable with fixups (IAT with more than 2 sections or a TLS section.) (Exception from HRESULT: 0x80131019)." The box pops up once, then the installer flashes its status to "rollback" then pops up another error box, then once 'ok'ed it procedes to rollback as usual. I don't understand that error message so i looked in the msi loggings and found this: "InstallShield 13:20:08: Initializing Property Bag...

The installers that I've tried(and failed) have always needed to be Setup.exes, when i try to build a .msi only setup I get this error message. It may help someone who knows more about this system than I do. Your project contains InstallShield prerequisites. A Setup.exe setup launcher is required if you are build a release that includes InstallShield prerequisites. Change your release settings to build Setup.exe, or remove the prerequisites from your project. -7076 There's nothing on the site that has anything from the error code, so I'm at a loss. Thanks for any help possible, I'm an intern and I'm fresh out of ideas... Josh System: XP SP3 Installshield 2010 Pro Install being tested on a VirtualPC

• Git for beginners: The definitive practical guide

  - by Adam Davis

  Ok, after seeing this post by PJ Hyett, I have decided to skip to the end and go with git. So what I need is a beginners practical guide to git. "Beginner" being defined as someone who knows how to handle their compiler, understands to some level what a makefile is, and has touched source control without understanding it very well. "Practical" being defined as this person doesn't want to get into great detail regarding what git is doing in the background, and doesn't even care (or know) that it's distributed. Your answers might hint at the possibilities, but try to aim for the beginner that wants to keep a 'main' repository on a 'server' which is backed up and secure, and treat their local repository as merely a 'client' resource. Procedural note: PLEASE pick one and only one of the below topics and answer it clearly and concisely in any given answer. Don't try to jam a bunch of information into one answer. Don't just link to other resources - cut and paste with attribution if copyright allows, otherwise learn it and explain it in your own words (ie, don't make people leave this page to learn a task). Please comment on, or edit, an already existing answer unless your explanation is very different and you think the community is better served with a different explanation rather than altering the existing explanation. So: Installation/Setup How to install git How do you set up git? Try to cover linux, windows, mac, think 'client/server' mindset. Setup GIT Server with Msysgit on Windows How do you create a new project/repository? How do you configure it to ignore files (.obj, .user, etc) that are not really part of the codebase? Working with the code How do you get the latest code? How do you check out code? How do you commit changes? How do you see what's uncommitted, or the status of your current codebase? How do you destroy unwanted commits? How do you compare two revisions of a file, or your current file and a previous revision? How do you see the history of revisions to a file? How do you handle binary files (visio docs, for instance, or compiler environments)? How do you merge files changed at the "same time"? How do you undo (revert or reset) a commit? Tagging, branching, releases, baselines How do you 'mark' 'tag' or 'release' a particular set of revisions for a particular set of files so you can always pull that one later? How do you pull a particular 'release'? How do you branch? How do you merge branches? How do you resolve conflicts and complete the merge? How do you merge parts of one branch into another branch? What is rebasing? How do I track remote branches? How can I create a branch on a remote repository? Other Describe and link to a good gui, IDE plugin, etc that makes git a non-command line resource, but please list its limitations as well as its good. msysgit - Cross platform, included with git gitk - Cross platform history viewer, included with git gitnub - OS X gitx - OS X history viewer smartgit - Cross platform, commercial, beta tig - console GUI for Linux qgit - GUI for Windows, Linux Any other common tasks a beginner should know? Git Status tells you what you just did, what branch you have, and other useful information How do I work effectively with a subversion repository set as my source control source? Other git beginner's references git guide git book git magic gitcasts github guides git tutorial Progit - book by Scott Chacon Git - SVN Crash Course Delving into git Understanding git conceptually I will go through the entries from time to time and 'tidy' them up so they have a consistent look/feel and it's easy to scan the list - feel free to follow a simple "header - brief explanation - list of instructions - gotchas and extra info" template. I'll also link to the entries from the bullet list above so it's easy to find them later.

• Using DateTime in a SqlParameter for Stored Procedure, format error

  - by Matt

  I'm trying to call a stored procedure (on a SQL 2005 server) from C#, .NET 2.0 using DateTime as a value to a SqlParameter. The SQL type in the stored procedure is 'datetime'. Executing the sproc from SQL Management Studio works fine. But everytime I call it from C# I get an error about the date format. When I run SQL Profiler to watch the calls, I then copy paste the exec call to see whats going on. These are my observations and notes about what I've attempted: 1) If I pass the DateTime in directly as a DateTime or converted to SqlDateTime, the field is surrounding by a PAIR of single quotes, such as @Date_Of_Birth=N''1/8/2009 8:06:17 PM'' 2) If I pass the DateTime in as a string, I only get the single quotes 3) Using SqlDateTime.ToSqlString() does not result in a UTC formatted datetime string (even after converting to universal time) 4) Using DateTime.ToString() does not result in a UTC formatted datetime string. 5) Manually setting the DbType for the SqlParameter to DateTime does not change the above observations. So, my questions then, is how on earth do I get C# to pass the properly formatted time in the SqlParameter? Surely this is a common use case, why is it so difficult to get working? I can't seem to convert DateTime to a string that is SQL compatable (e.g. '2009-01-08T08:22:45') EDIT RE: BFree, the code to actually execute the sproc is as follows: using (SqlCommand sprocCommand = new SqlCommand(sprocName)) { sprocCommand.Connection = transaction.Connection; sprocCommand.Transaction = transaction; sprocCommand.CommandType = System.Data.CommandType.StoredProcedure; sprocCommand.Parameters.AddRange(parameters.ToArray()); sprocCommand.ExecuteNonQuery(); } To go into more detail about what I have tried: parameters.Add(new SqlParameter("@Date_Of_Birth", DOB)); parameters.Add(new SqlParameter("@Date_Of_Birth", DOB.ToUniversalTime())); parameters.Add(new SqlParameter("@Date_Of_Birth", DOB.ToUniversalTime().ToString())); SqlParameter param = new SqlParameter("@Date_Of_Birth", System.Data.SqlDbType.DateTime); param.Value = DOB.ToUniversalTime(); parameters.Add(param); SqlParameter param = new SqlParameter("@Date_Of_Birth", SqlDbType.DateTime); param.Value = new SqlDateTime(DOB.ToUniversalTime()); parameters.Add(param); parameters.Add(new SqlParameter("@Date_Of_Birth", new SqlDateTime(DOB.ToUniversalTime()).ToSqlString())); Additional EDIT The one I thought most likely to work: SqlParameter param = new SqlParameter("@Date_Of_Birth", System.Data.SqlDbType.DateTime); param.Value = DOB; Results in this value in the exec call as seen in the SQL Profiler @Date_Of_Birth=''2009-01-08 15:08:21:813'' If I modify this to be @Date_Of_Birth='2009-01-08T15:08:21' It works, but it won't parse with pair of single quotes, and it wont convert to a datetime correctly with the space between the date and time and with the milliseconds on the end. Update and Success First and foremost, thank you everyone for the answers. I post this for the sake of completeness and accuracy on SO - because I certainly do not do it for my pride... I had copy/pasted the code above after the request from below. I trimmed things here and there to be concise. Turns out my problem was in the code I left out, which I'm sure any one of you would have spotted in an instant. I had wrapped my sproc calls inside a transaction. Turns out that I was simply not doing transaction.Commit()!!!!! I'm ashamed to say it, but there you have it. I still don't know what's going on with the syntax I get back from the profiler. A coworker watched with his own instance of the profiler from his computer, and it returned proper syntax. Watching the very SAME executions from my profiler showed the incorrect syntax. It acted as a red-herring, making me believe there was a query syntax problem instead of the much more simple and true answer, which was that I need to commit the transaction! I marked an answer below as correct, and threw in some up-votes on others because they did, after all, answer the question, even if they didn't fix my specific (brain lapse) issue. Thanks again for the help.

• Looking for feedback on a first SAML implementation.

  - by morgancodes

  Hello, I've been tasked with designing a very simple SSO (single sign-on) process. My employer has specified that it should be implimented in SAML. I'd like to create messages that are absolutely as simple as possible while confirming to the SAML spec. I'd be really grateful if some of you would look at my request and response messages and tell me if they make sense for my purpose, if they include anything that doesn't need to be there, and if they are missing anything that does need to be there. Addionally, I'd like to know where in the response I should put additional information about the subject; in particular, the subject's email address. The interaction needs to work as follows: 1) User requests service from service provider at this point, the service provider knows nothing about the user. 2) Service provider requests authentication for user from identity provider 3) User is authenticated/registered by identity provider 4) Identity provider responds to Service provider with authentication success message, PLUS user's email address. Here's what I think the request should be: <?xml version="1.0" encoding="UTF-8"?> <samlp:AuthnRequest xmlns:samlp="urn:oasis:names:tc:SAML:2.0:protocol" ID="abc" IssueInstant="1970-01-01T00:00:00.000Z" Version="2.0" AssertionConsumerServiceURL="http://www.IdentityProvider.com/loginPage"> <saml:Issuer xmlns:saml="urn:oasis:names:tc:SAML:2.0:assertion"> http://www.serviceprovider.com </saml:Issuer> <saml:Subject> <saml:NameID Format="urn:oasis:names:tc:SAML:2.0:nameid-format:transient">3f7b3dcf-1674-4ecd-92c8-1544f346baf8</saml:NameID> </saml:Subject> Here's what I think the response should be: <?xml version="1.0" encoding="UTF-8"?> <samlp:Response xmlns:samlp="urn:oasis:names:tc:SAML:2.0:protocol" Destination="http://www.serviceprovider.com/desitnationURL" ID="123" IssueInstant="2008-11-21T17:13:42.872Z" Version="2.0"> <samlp:Status> <samlp:StatusCode Value="urn:oasis:names:tc:SAML:2.0:status:Success"/> </samlp:Status> <saml:Assertion xmlns:saml="urn:oasis:names:tc:SAML:2.0:assertion" Version="2.0"> <saml:Subject> <saml:NameID Format="urn:oasis:names:tc:SAML:2.0:nameid-format:transient">3f7b3dcf-1674-4ecd-92c8-1544f346baf8</saml:NameID> <saml:SubjectConfirmation Method="urn:oasis:names:tc:SAML:2.0:profiles:SSO:browser"> <saml:SubjectConfirmationData InResponseTo="abc"/> </saml:SubjectConfirmation> </saml:Subject> <saml:AuthnStatement AuthnInstant="2008-11-21T17:13:42.899Z"> <saml:AuthnContext> <saml:AuthnContextClassRef>urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport</saml:AuthnContextClassRef> </saml:AuthnContext> </saml:AuthnStatement> </saml:Assertion> </samlp:Response> So, again, my questions are: 1) Is this a valid SAML interaction? 2) Can either the request or response xml be simplified? 3) Where in the response should I put the subject's email address? I really apprecaite your help. Thanks so much! -Morgan

  - by uzay95

  I am dynamically load js files with _tumIsler.js (_allStuff.js) <script src="../js/_tumJsler.js" type="text/javascript"></script> It contains: // url=> http: + // + localhost:4399 + /yabant/ // ---- ---- -------------- -------- // protocol + "//" + host + '/virtualDirectory/' var baseUrl = document.location.protocol + "//" + document.location.host + '/yabant/'; // If there is "~/" at the begining of url, replace it with baseUrl function ResolveUrl(url) { if (url.indexOf("~/") == 0) { url = baseUrl + url.substring(2); } return url; } // Attaching scripts to any tag function addJavascript(jsname, pos) { var th = document.getElementsByTagName(pos)[0]; var s = document.createElement('script'); s.setAttribute('type', 'text/javascript'); s.setAttribute('src', jsname); th.appendChild(s); } // I want to make sure jQuery is loaded? addJavascript(ResolveUrl('~/js/1_jquery-1.4.2.min.js'), 'head'); var loaded = false; // assume it didn't first and if it is change it to true function fControl() { // alert("JQUERY is loaded?"); if (typeof jQuery == 'undefined') { loaded = false; fTry2LoadJquery(); } else { loaded = true; fGetOtherScripts(); } } // Check is jQuery loaded fControl(); function fTry2LoadJquery() { // alert("JQUERY didn't load!

Are they always downloading in every $.getScript requests?

• SQLAlchemy session management in long-running process

  - by codeape

  Scenario: A .NET-based application server (Wonderware IAS/System Platform) hosts automation objects that communicate with various equipment on the factory floor. CPython is hosted inside this application server (using Python for .NET). The automation objects have scripting functionality built-in (using a custom, .NET-based language). These scripts call Python functions. The Python functions are part of a system to track Work-In-Progress on the factory floor. The purpose of the system is to track the produced widgets along the process, ensure that the widgets go through the process in the correct order, and check that certain conditions are met along the process. The widget production history and widget state is stored in a relational database, this is where SQLAlchemy plays its part. For example, when a widget passes a scanner, the automation software triggers the following script (written in the application server's custom scripting language): ' wiget_id and scanner_id provided by automation object ' ExecFunction() takes care of calling a CPython function retval = ExecFunction("WidgetScanned", widget_id, scanner_id); ' if the python function raises an Exception, ErrorOccured will be true ' in this case, any errors should cause the production line to stop. if (retval.ErrorOccured) then ProductionLine.Running = False; InformationBoard.DisplayText = "ERROR: " + retval.Exception.Message; InformationBoard.SoundAlarm = True end if; The script calls the WidgetScanned python function: # pywip/functions.py from pywip.database import session from pywip.model import Widget, WidgetHistoryItem from pywip import validation, StatusMessage from datetime import datetime def WidgetScanned(widget_id, scanner_id): widget = session.query(Widget).get(widget_id) validation.validate_widget_passed_scanner(widget, scanner) # raises exception on error widget.history.append(WidgetHistoryItem(timestamp=datetime.now(), action=u"SCANNED", scanner_id=scanner_id)) widget.last_scanner = scanner_id widget.last_update = datetime.now() return StatusMessage("OK") # ... there are a dozen similar functions My question is: How do I best manage SQLAlchemy sessions in this scenario? The application server is a long-running process, typically running months between restarts. The application server is single-threaded. Currently, I do it the following way: I apply a decorator to the functions I make avaliable to the application server: # pywip/iasfunctions.py from pywip import functions def ias_session_handling(func): def _ias_session_handling(*args, **kwargs): try: retval = func(*args, **kwargs) session.commit() return retval except: session.rollback() raise return _ias_session_handling # ... actually I populate this module with decorated versions of all the functions in pywip.functions dynamically WidgetScanned = ias_session_handling(functions.WidgetScanned) Question: Is the decorator above suitable for handling sessions in a long-running process? Should I call session.remove()? The SQLAlchemy session object is a scoped session: # pywip/database.py from sqlalchemy.orm import scoped_session, sessionmaker session = scoped_session(sessionmaker()) I want to keep the session management out of the basic functions. For two reasons: There is another family of functions, sequence functions. The sequence functions call several of the basic functions. One sequence function should equal one database transaction. I need to be able to use the library from other environments. a) From a TurboGears web application. In that case, session management is done by TurboGears. b) From an IPython shell. In that case, commit/rollback will be explicit. (I am truly sorry for the long question. But I felt I needed to explain the scenario. Perhaps not necessary?)

• Ad Server does not serve ads in Firefox, but works fine in Chrome, IE, & Safari!?

  - by HipHop-opatamus

  I'm having a strange (likely JavaScript) related issue. I'm running Open X Ad Server ( http://www.openx.org ) which serves ads to the website http://upsidedowndogs.com . The ads load fine every time when visiting the site via Chrome, IE, or Safari, but sometimes don't load at all in FireFox - Hence, it is a client side issue, which leads me to believe its something up with the javascript. The fact that the problem is intermittent, and does not through any error codes to FireBug, also doesn't make it any easier to diagnose and address. Any ideas how to diagnose / address this issue? Thanks! Here is the code generated by OpenX (it goes in the page header - additional code is then used in each ad unit, as seen on the page) if (typeof(OA_zones) != 'undefined') { var OA_zoneids = ''; for (var zonename in OA_zones) OA_zoneids += escape(zonename+'=' + OA_zones[zonename] + "|"); OA_zoneids += '&amp;nz=1'; } else { var OA_zoneids = escape('1|2|3|4'); } if (typeof(OA_source) == 'undefined') { OA_source = ''; } var OA_p=location.protocol=='https:'?'https://ads.offleashmedia.com/server/www/delivery/spc.php':'http://ads.offleashmedia.com/server/www/delivery/spc.php'; var OA_r=Math.floor(Math.random()*99999999); OA_output = new Array(); var OA_spc="<"+"script type='text/javascript' "; OA_spc+="src='"+OA_p+"?zones="+OA_zoneids; OA_spc+="&amp;source="+escape(OA_source)+"&amp;r="+OA_r; OA_spc+=(document.charset ?

• WYSIHAT 'resonds_to_parent" undefined method - Ruby on Rails

  - by bgadoci

  I just successfully installed WysiHat in my rails blog. Seems that the 'add a picture' feature is not working. It successfully allows me to find and select a picture from my desktop but upon clicking save, it does nothing. I also have Paperclip successfully installed and can attach images to records outside the WYSIHAT form field. Any ideas? (let me know if I need to post any code). Also, WysiHat-engine uses facebox, not sure if that is relevant. UPDATE: Added Server Log, looks like paperclip is saving it so not sure what else is going wrong.

• sending a $_SESSION array to my class and attempting to get the value fro it in a for loop .php

  - by eoin

  i have a class which in which iam using a method to get information from a session array via a for loop the 2 for loops in each method are used 1.to count total amount of items , and 2. to add up the total price but neither seem to be returning anything. im using the total amount to check it against the mc_gross posted value from an IPN and if the values are equal i plan to commit the sale to a database as it has been verified. for the method where im looking to get the total price im getting 0.00 returned to me. i think ive got the syntax wrong here somehow here is my class for purchase the two methods iam having trouble with are the gettotalcost() and gettotalitems() shown below is my class. <?php class purchase { private $itemnames; // from session array private $amountofitems; // from session array private $itemcost; //session array private $saleid; //posted transaction id value to be used in sale and sale item tables private $orderdate; //get current date time to be entered as datetime in sale table private $lastname; //posted from ipn private $firstname; //posted from ipn private $emailadd; //uses sessionarray value public function __construct($saleid,$firstname,$lastname) { $this->itemnames = $_SESSION['itemnames']; $this->amountofitems =$_SESSION['quantity']; $this->itemcost =$_SESSION['price']; $this->saleid = $saleid; $this->firstname = $firstname; $this->lastname = $lastname; $this->emailadd = $SESSION['username']; mail($myemail, "session vardump ", echo var_dump($_SESSION), "From: [email protected]" ); mail($myemail, "session vardump ",count($_SESSION['itemnames']) , "From: [email protected]" ); } public function commit() { $databaseinst = database::getinstance(); $databaseinst->connect(); $numrows = $databaseinst->querydb($query); //to be completed } public function gettotalitems() { $numitems; $i; for($i=0; $i < count($this->amountofitems);$i++) { $numitems += (int) $this->amountofitems[$i]; } return $numitems; } public function gettotalcost() { $totalcost; $i; for($i=0; $i < count($this->amountofitems);$i++) { $numitems = (int) $this->amountofitems[$i]; $costofitem =doubleval($this->itemcost [$i]); $totalcost += $numitems * $costofitem; } return $totalcost; } } ?> and here is where i create an instance of the class and attempt to use it. include("purchase.php"); $purchase = new purchase($_POST['txn_id'],$_POST['first_name'],$_POST['last_name']); $fullamount = $purchase->gettotalcost(); $fullAmount = number_format($fullAmount, 2); $grossAmount = $_POST['mc_gross']; if ($fullAmount != $grossAmount) { $message = "Possible Price Jack attempt! the amount the customer payed is : " . $grossAmount . " which is not equal to the full amount. the price of the products combined is " . $fullAmount. " the transaction number for which is " . $_POST['txn_id'] . "\n\n\n$req"; mail("XXXXXXXXXXXX", "Price Jack attempt ", $message, "From: [email protected]" ); exit(); // exit } thanks for the help in advance! ive also added these lines to my constructor. the mail returns that there is nothing in the vardump uh oh! mail($myemailaddress, "session vardump ", var_dump($_SESSION), "From: [email protected]" ); also added session_start(); at the top of the constructor and it dont work! help

• NSUserDefaults loses 3 rows each time it's called

  - by Jeff Decker

  Hello Everyone! Brand new programmer here, so off-topic help/constructive criticism welcome. I am saving a default state (such as "New York") in a UIPickerView which is in a FlipSideView. It certainly saves for the first and second time I check to make sure it's the same state (I am clicking "done" and then "info" repeatedly), but on the third check the picker has moved up three states (to "New Hampshire") and then every time I check the picker progresses three more states. Here's the .h and .m files of the FlipSideViewController: #import <UIKit/UIKit.h> import "Calculator.h" @protocol FlipsideViewControllerDelegate; @interface FlipsideViewController : UIViewController { id delegate; UIPickerView *myPickerView; NSArray *pickerViewArray; } @property (nonatomic, assign) id delegate; @property (nonatomic, retain) UIPickerView *myPickerView; @property (nonatomic, retain) NSArray *pickerViewArray; (IBAction)done; @end @protocol FlipsideViewControllerDelegate - (void)flipsideViewControllerDidFinish:(FlipsideViewController *)controller; @end import "FlipsideViewController.h" @implementation FlipsideViewController @synthesize delegate; @synthesize myPickerView, pickerViewArray; -(CGRect)pickerFrameWithSize:(CGSize)size;{ CGRect screenRect = [[UIScreen mainScreen] applicationFrame]; CGRect pickerRect = CGRectMake( 0.0, screenRect.size.height - size.height, size.width, size.height); return pickerRect; } (void)viewDidLoad { [super viewDidLoad]; self.view.backgroundColor = [UIColor viewFlipsideBackgroundColor]; [self createPicker]; } -(void)viewWillAppear:(BOOL)animated;{ [super viewWillAppear:NO]; NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; [myPickerView selectRow:[defaults integerForKey:@"pickerRow"] inComponent:0 animated:NO]; } -(void)createPicker;{ pickerViewArray = [[NSArray arrayWithObjects: @"Alabama",@"Alaska", @"Arizona",@"Arkansas",@"California",@"Colorado",@"Connecticut",@"Delaware", @"District of Columbia",@"Florida",@"Georgia",@"Hawaii",@"Idaho",@"Illinois",@"Indiana",@"Iowa", @"Kansas",@"Kentucky",@"Louisiana",@"Maine",@"Maryland",@"Massachusetts",@"Michigan", @"Minnesota",@"Mississippi",@"Missouri",@"Montana",@"Nebraska",@"Nevada",@"New Hampshire",@"New Jersey", @"New Mexico",@"New York",@"North Carolina",@"North Dakota",@"Ohio",@"Oklahoma", @"Oregon",@"Pennsylvania",@"Rhode Island",@"South Carolina",@"South Dakota",@"Tennessee", @"Texas",@"Utah",@"Vermont",@"Virginia",@"Washington",@"West Virginia",@"Wisconsin",@"Wyoming", nil] retain]; myPickerView = [[UIPickerView alloc] initWithFrame:CGRectZero]; CGSize pickerSize = [myPickerView sizeThatFits:CGSizeZero]; myPickerView.frame = [self pickerFrameWithSize:pickerSize]; myPickerView.autoresizingMask = UIViewAutoresizingFlexibleWidth; myPickerView.showsSelectionIndicator = YES; myPickerView.delegate = self; myPickerView.dataSource = self; [self.view addSubview:myPickerView]; } (IBAction)done { [self.delegate flipsideViewControllerDidFinish:self]; } pragma mark - pragma mark UIPickerViewDataSource (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component { NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; [defaults setInteger:row forKey:@"pickerRow"]; [defaults setObject:[pickerViewArray objectAtIndex:row] forKey:@"pickerString"]; return [pickerViewArray objectAtIndex:row]; } (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component { NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; [defaults setInteger:row forKey:@"pickerRow"]; [defaults setObject:[pickerViewArray objectAtIndex:row] forKey:@"pickerString"]; } (CGFloat)pickerView:(UIPickerView *)pickerView widthForComponent:(NSInteger)component { return 240.0; } (CGFloat)pickerView:(UIPickerView *)pickerView rowHeightForComponent:(NSInteger)component { return 40.0; } (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component { return [pickerViewArray count]; } (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView { return 1; } call me mystified! Thanks for any help. Please let me know if I can make myself more clear...

• Better, simpler example of 'semantic conflict'?

  - by rhubbarb

  I like to distinguish three different types of conflict from a version control system (VCS): textual syntactic semantic A textual conflict is one that is detected by the merge or update process. This is flagged by the system. A commit of the result is not permitted by the VCS until the conflict is resolved. A syntactic conflict is not flagged by the VCS, but the result will not compile. Therefore this should also be picked up by even a slightly careful programmer. (A simple example might be a variable rename by Left and some added lines using that variable by Right. The merge will probably have an unresolved symbol. Alternatively, this might introduce a semantic conflict by variable hiding.) Finally, a semantic conflict is not flagged by the VCS, the result compiles, but the code may have problems running. In mild cases, incorrect results are produced. In severe cases, a crash could be introduced. Even these should be detected before commit by a very careful programmer, through either code review or unit testing. My example of a semantic conflict uses SVN (Subversion) and C++, but those choices are not really relevant to the essence of the question. The base code is: int i = 0; int odds = 0; while (i < 10) { if ((i & 1) != 0) { odds *= 10; odds += i; } // next ++ i; } assert (odds == 13579) The Left (L) and Right (R) changes are as follows. Left's 'optimisation' (changing the values the loop variable takes): int i = 1; // L int odds = 0; while (i < 10) { if ((i & 1) != 0) { odds *= 10; odds += i; } // next i += 2; // L } assert (odds == 13579) Right's 'optimisation' (changing how the loop variable is used): int i = 0; int odds = 0; while (i < 5) // R { odds *= 10; odds += 2 * i + 1; // R // next ++ i; } assert (odds == 13579) This is the result of a merge or update, and is not detected by SVN (which is correct behaviour for the VCS). int i = 1; // L int odds = 0; while (i < 5) // R { odds *= 10; odds += 2 * i + 1; // R // next i += 2; // L } assert (odds == 13579) The assert fails because odds is 37. So my question is as follows. Is there a simpler example than this? Is there a simple example where the compiled executable has a new crash? As a secondary question, are there cases of this that you have encountered in real code? Again, simple examples are especially welcome.
