Determining when stringByEvaluatingJavaScriptFromString has finished

- by alku83

I have a UIWebView which loads up an HTML page. This page has two buttons on it, say Exit and Submit. I don't want users to be able to click the Exit button, so once the page has finished loading (ie. webViewDidFinishLoad is called), I use stringByEvaluatingJavaScriptFromString to remove one of these buttons, by manipulating the HTML. I also disable user interaction on the UIWebView on webViewDidStartLoad, and enable it again on webViewDidFinishLoad. The problem I am finding is that stringByEvaluatingJavaScriptFromString takes a second or two to complete, and it seems to be done in it's own thread. So what is happening is that webViewDidFinishLoad is called, user interaction is enabled on the UIWebView, and if the user is quick, they can click the Exit button before stringByEvaluatingJavaScriptFromString has finished. As stringByEvaluatingJavaScriptFromString seems to be on it's own thread with no way to know when it's finished (it doesnt call webViewDidFinishLoad), the only way to completely prevent users from tapping the Exit button that I can see is to only enable user interaction on the UIWebView after some delay, which is unreliable (how can I really know how long to delay for?). Am I correct in that stringByEvaluatingJavaScriptFromString is done on it's on thread, and I have no way of being able to tell when it's finished? Any other suggestions for how to get around this problem? EDIT: In short, what I want to know is if it is possible to disable a UIWebView while stringByEvaluatingJavaScriptFromString is executing, and re-enable the UIWebView when the javascript is finished. EDIT 2: There's an article here which seems to imply you can somehow poll the JS engine to see when it's finished, but I can't find any other references saying the same thing: http://drnicwilliams.com/2008/11/10/to-webkit-or-not-to-webkit-within-your-iphone-app/ EDIT 3 Based on the answer from Brad Smith, it seems that I actually need to know when the UIWebView has finished loading itself after the javascript has executed. It's looking more and more like I just need to put a delay of sorts in there.

Group vs role (Any real difference?)

- by Ondrej

Can anyone tell me, what's the real difference between group and role? Ive been trying to figure this out for some time now and the more information I read, the more I get the sence, that this is brought up just to confuse people and there is no proper difference in this. Both can do the other one's job. Ive always used a group to manage users and their access rights. Recently, I've come accross an administration software, where is a bunch of users. Each user can have assigned a module (whole system is split into a few parts called modules ie. Administration module, Survey module, Orders module, Customer module). On top of it, each module have a list of functionalities, that can be allowed or denied for each user. So let's say, a user John Smith can access module Orders and can edit any order, but havent given a right to delete any of them. If there was more users with the same competency, I would use a group to manage that. I would aggregate such users into the same group and assign access rights to modules and their functions to the group. All users in the same group would have the same access rights. Why call it a group and not role? I don't know, I just feel it that way. It seems to me, that simply it just doesnt really matter :] But I still would like to know the real difference. What about you guys? Any suggestions why this should be rather called role than group or the other way round? Thanks to everyone.

Implementing a c/c++ style union as a column in MySQL

- by user81338

Friends, I have a strange need and cannot think my way through the problem. The great and mighty Google is of little help due to keyword recycling (as you'll see). Can you help? What I want to do is store data of multiple types in a single column in MySQL. This is the database equivalent to a C union (and if you search for MySQL and Union, you obviously get a whole bunch of stuff on the UNION keyword in SQL). [Contrived and simplified case follows] So, let us say that we have people - who have names - and STORMTROOPERS - who have TK numbers. You cannot have BOTH a NAME and a TK number. You're either BOB SMITH -or- TK409. In C I could express this as a union, like so: union { char * name; int tkNo; } EmperialPersonnelRecord; This makes it so that I am either storing a pointer to a char array or an ID in the type EmperialPersonnelRecord, but not both. I am looking for a MySQL equivalent on a column. My column would store either an int, double, or varchar(255) (or whatever combination). But would only take up the space of the largest element. Is this possible? (of course anything is possible given enough time, money and will - I mean is it possible if I am poor, lazy and on a deadline... aka "out of the box")

Excessive use of Inner Join for more than 3 tables

- by Archangel08

Good Day, I have 4 tables on my DB (not the actual name but almost similar) which are the ff: employee,education,employment_history,referrence employee_id is the name of the foreign key from employee table. Here's the example (not actual) data: **Employee** ID Name Birthday Gender Email 1 John Smith 08-15-2014 Male [email protected] 2 Jane Doe 00-00-0000 Female [email protected] 3 John Doe 00-00-0000 Male [email protected] **Education** Employee_ID Primary Secondary Vocation 1 Westside School Westshore H.S SouthernBay College 2 Eastside School Eastshore H.S NorthernBay College 3 Northern School SouthernShore H.S WesternBay College **Employment_History** Employee_ID WorkOne StartDate Enddate 1 StarBean Cafe 12-31-2012 01-01-2013 2 Coffebucks Cafe 11-01-2012 11-02-2012 3 Latte Cafe 01-02-2013 04-05-2013 Referrence Employee_ID ReferrenceOne Address Contact 1 Abraham Lincoln Lincoln Memorial 0000000000 2 Frankie N. Stein Thunder St. 0000000000 3 Peter D. Pan Neverland Ave. 0000000000 NOTE: I've only included few columns though the rest are part of the query. And below are the codes I've been working on for 3 consecutive days: $sql=mysql_query("SELECT emp.id,emp.name,emp.birthday,emp.pob,emp.gender,emp.civil,emp.email,emp.contact,emp.address,emp.paddress,emp.citizenship,educ.employee_id,educ.elementary,educ.egrad,educ.highschool,educ.hgrad,educ.vocational,educ.vgrad,ems.employee_id,ems.workOne,ems.estartDate,ems.eendDate,ems.workTwo,ems.wstartDate,ems.wendDate,ems.workThree,ems.hstartDate,ems.hendDate FROM employee AS emp INNER JOIN education AS educ ON educ.employee_id='emp.id' INNER JOIN employment_history AS ems ON ems.employee_id='emp.id' INNER JOIN referrence AS ref ON ref.employee_id='emp.id' WHERE emp.id='$id'"); Is it okay to use INNER JOIN this way? Or should I modify my query to get the results that I wanted? I've also tried to use LEFT JOIN but still it doesn't return anything .I didn't know where did I go wrong. You see, as I have thought, I've been using the INNER JOIN in correct manner, (since it was placed before the WHILE CLAUSE). So I couldn't think of what could've possible went wrong. Do you guys have a suggestion? Thanks in advance.

FileHelpers cannot map converted field into destination array

- by jaffa

I have the following record (reduced for brevity): [DelimitedRecord(",")] [IgnoreFirst] [IgnoreEmptyLines()] public class ImportRecord { [FieldQuoted] [FieldTrim(TrimMode.Both)] public string FirstName; [FieldQuoted] [FieldTrim(TrimMode.Both)] public string LastName; [FieldQuoted] [FieldTrim(TrimMode.Both)] [FieldOptional] [FieldConverter(typeof(TestPropertyConverter))] public int[] TestProperty; } Converter code: public class TestPropertyConverter : ConverterBase { public override object StringToField(string from) { var ret = from.Split('|').Select(x => Convert.ToInt32(x)).ToArray(); return ret; } } So an example record could be: John, Smith, 1|2|3|4 It would expect the values 1,2,3,4 to expand and fill the TestProperty array. However, I'm getting the following exception: At least one element in the source array could not be cast down to the destination array type. I've tried to debug into the code and it seems to blow-up in the ExtractFieldValue() function inside FieldBase.cs where it tries to return out of the function. The following line seems to be the culprit: res.ToArray(ArrayType); It seems to expect the 'res' variable to be the destination type array, but it contains 1 element of the array itself. Can anyone suggest if I'm doing this wrong or a possible fix?

Is it Possible to Use Constraints on Hierarchical Data in a Self-Referential Table?

- by pbarney

Suppose you have the following table, intended to represent hierarchical data: +--------+-------------+ | Field | Type | +--------+-------------+ | id | int(10) | | parent | int(10) | | name | varchar(45) | +--------+-------------+ The table is self-referential in that the parent_id refers to id. So you might have the following data: +----+--------+---------------+ | id | parent | name | +----+--------+---------------+ | 1 | 0 | fruit | | 2 | 0 | vegetable | | 3 | 1 | apple | | 4 | 1 | orange | | 5 | 3 | red delicious | | 6 | 3 | granny smith | | 7 | 3 | gala | +----+--------+---------------+ Using MySQL, I am trying to impose a (self-referential) foreign key constraint upon the data to cascade on update and prevent deletion of a record if it has any "children." So I used the following: CREATE TABLE `test`.`fruit` ( `id` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT, `parent` INT(10) UNSIGNED, `name` VARCHAR(45) NOT NULL, PRIMARY KEY (`id`), CONSTRAINT `fk_parent` FOREIGN KEY (`parent`) REFERENCES `fruit` (`id`) ON UPDATE CASCADE ON DELETE RESTRICT ) ENGINE = InnoDB; From what I understand, this should fit my requirements. (And parent must default to null to allow insertions, correct?) The problem is, if I change the id of a record, it will not cascade: Cannot delete or update a parent row: a foreign key constraint fails (`test`.`fruit`, CONSTRAINT `fk_parent` FOREIGN KEY (`parent`) REFERENCES `fruit` (`id`) ON UPDATE CASCADE) What am I missing? Feel free to correct me if my terminology is screwed up... I'm new to constraints.

UI - How I can make users effectively read what my program says?

- by Magnetic_dud

I have a simple form that searches through the 2000+ issues of a 3rd party webcomic. (Easy, it's like xkcd: http://url/number That form is as easy as possible, is like this: What number do you want? User writes a number, clicks ok, and goes on the 3rd party website on a new tab Then, my form asks a question: "Did you find that issue memorable? Enter the name here, and we will add it to the "best issues" in home page" When the user will write the name of the issue, it is added to the database (pending moderation by me) So, I supposed this design is the easiest and convenient that users can find. Unfortunately, NONE of the users (maybe a 2% behaved correctly) will actually read what I asked. Some of the issues are offline, and gives a 404. On that issues users will write in the textbox a completely wrong title, and correctly capitalized! It's like if i would name http://xkcd.com/627/ as "The Great Adventures of Jack Smith" Users are from around all over the country, with different browsers, and have a different cookie. I cannot believe that my users will not read what I ask, it is a WHITE PAGE with a button that disappears when clicked and a textbox.... easier than that??? Maybe i should put a checkbox with "I acknowledge that this form is for submitting memorable issues, not for fun"? Oh, who will read that? Or maybe i could enable the textbox only if the user has effectively clicked the link?

MySQL running on an EC2 m1.small instance has high load but low memory usage, possible resolutions?

- by Tosh

I have a MySQL server 5.0.75 Ubuntu, on an m1.small instance running on Amazon's EC2 as part of an application. During peak usage the server load will rise very high, while the memory usage stays low and the application server is no longer responsive since it's waiting for query results. The application server has only 5-8 apache processes running (mod_perl processes). The data directory uses only 140MB of data so the MyIsam tables aren't very big. The queries are pretty complicated with some big joins being performed, and the application makes a lot of queries. mysqltuner reports everything OK except "Maximum possible memory usage: 1.7G (99% of installed RAM)" but I'm nowhere close to using that. My question is, where should I be looking to fix this? Is this something that can be tuned away, or do I just need a larger instance/server? Googling indicates either or also upgrading MySQL server. Any pointers in the right direction would be greatly appreciated, thanks! EDIT: I just discovered this in my slow queries log: # Time: 101116 11:17:00 # User@Host: user[pass] @ [host] # Query_time: 4063 Lock_time: 1035 Rows_sent: 0 Rows_examined: 19960174 SELECT * FROM contacts WHERE contacts.contact_id IN (SELECT external_id FROM contact_relations WHERE external_table = 'contacts' AND contact_id IN (SELECT contact_id FROM contacts WHERE (company_name like '%%butan%%%' OR country like '%%butan%%%' OR city like '%%butan%%%' OR email1 like '%%butan%%%') AND (company_name is not null and company_name != ''))); Which actually brings up a different but related question: If I have a contact table containing: John Smith,The Fun Factory,555-1212,[email protected] What's the best way to search for that record using "factory" as a search key? Fulltext rarely seems to find items in the middle of a word, for example "actor" should bring up "Factory"

Predicate usually used for array/list how about here?

- by amit kohan

In following code (Josh Smith's article on MVVM), can somebody give me some insight about return _canExecute == null ? true : _canExecute(parameter); ? it is a normal if/else statement but I'm not getting the last part of it. public class RelayCommand : ICommand { #region Fields readonly Action<object> _execute; readonly Predicate<object> _canExecute; #endregion // Fields #region Constructors public RelayCommand(Action<object> execute) : this(execute, null) { } public RelayCommand(Action<object> execute, Predicate<object> canExecute) { if (execute == null) throw new ArgumentNullException("execute"); _execute = execute; _canExecute = canExecute; } #endregion // Constructors #region ICommand Members [DebuggerStepThrough] public bool CanExecute(object parameter) { return _canExecute == null ? true : _canExecute(parameter); } public event EventHandler CanExecuteChanged { add { CommandManager.RequerySuggested += value; } remove { CommandManager.RequerySuggested -= value; } } public void Execute(object parameter) { _execute(parameter); } #endregion // ICommand Members } Thanks.

Contacts & Autocomplete

- by Vince

First post. I'm new to android and programming in general. What I'm attempting to is to have an autocomplete text box pop up with auto complete names from the contact list. IE, if they type in "john" it will say "John Smith" or any john in their contacts. The code is basic, I pulled it from a few tutorials. private void autoCompleteBox() { ContentResolver cr = getContentResolver(); Uri contacts = Uri.parse("content://contacts/people"); Cursor managedCursor1 = cr.query(contacts, null, null, null, null); if (managedCursor1.moveToFirst()) { String contactname; String cphoneNumber; int nameColumn = managedCursor1.getColumnIndex("name"); int phoneColumn = managedCursor1.getColumnIndex("number"); Log.d("int Name", Integer.toString(nameColumn)); Log.d("int Number", Integer.toString(phoneColumn)); do { // Get the field values contactname = managedCursor1.getString(nameColumn); cphoneNumber = managedCursor1.getString(phoneColumn); if ((contactname != " " || contactname != null) && (cphoneNumber != " " || cphoneNumber != null)) { c_Name.add(contactname); c_Number.add(cphoneNumber); Toast.makeText(this, contactname, Toast.LENGTH_SHORT) .show(); } } while (managedCursor1.moveToNext()); } name_Val = (String[]) c_Name.toArray(new String[c_Name.size()]); phone_Val = (String[]) c_Number.toArray(new String[c_Name.size()]); ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_dropdown_item_1line, name_Val); personName.setAdapter(adapter); } personName is my autocompletetextbox. So it actually works when I use it in the emulator (4.2) with manually entered contacts through the people app, but when I use it on my device, it will not pop up with any names. I'm sure it's something ridiculous but I've tried to find the answer and I'm getting nowhere. Can't learn if I don't ask.

Best way to limit results in MySQL with user subcategories

- by JM4

I am trying to essentially solve for the following: 1) Find all users in the system who ONLY have programID 1. 2) Find all users in the system who have programID 1 AND any other active program. My tables structures (in very simple terms are as follows): users userID | Name ================ 1 | John Smith 2 | Lewis Black 3 | Mickey Mantle 4 | Babe Ruth 5 | Tommy Bahama plans ID | userID | plan | status --------------------------- 1 | 1 | 1 | 1 2 | 1 | 2 | 1 3 | 1 | 3 | 1 4 | 2 | 1 | 1 5 | 2 | 3 | 1 6 | 3 | 1 | 0 7 | 3 | 2 | 1 8 | 3 | 3 | 1 9 | 3 | 4 | 1 10 | 4 | 2 | 1 11 | 4 | 4 | 1 12 | 5 | 1 | 1 I know I can easily find all members with a specific plan with something like the following: SELECT * FROM users a JOIN plans b ON (a.userID = b.userID) WHERE b.plan = 1 AND b.status = 1 but this will only tell me which users have an 'active' plan 1. How can I tell who ONLY has plan 1 (in this case only userID 5) and how to tell who has plan 1 AND any other active plan? Update: This is not to get a count, I will actually need the original member information, including all the plans they have so a COUNT(*) response may not be what I'm trying to achieve.

AttributeError in my Python program regarding classes

- by Axel Finkel

I'm doing an exercise out of the Python book that involves creating a class and a subclass. I am getting the following error when I try to run the program: AttributeError: 'Customer' object has no attribute 'name', when it tries to go through this bit of code: self.name.append(name) As this is my first time dealing with classes and objects in Python, I'm sure I am making some overt mistake somewhere, but I can't seem to figure it out. I've looked over the documentation for creating classes and writing member functions, and it looks correct, but it is obviously not. I want the Customer subclass to inherit the name, address, and telephone attributes from the Person superclass, but it doesn't seem to be doing so? Here is my code: class Person: def __init__(self): self.name = None self.address = None self.telephone = None def changeName(self, name): self.name.append(name) def changeAddress(self, address): self.address.append(address) def changeTelephone(self, telephone): self.telephone.append(telephone) class Customer(Person): def __init__(self): self.customerNumber = None self.onMailingList = False def changeCustomerNumber(self, customerNumber): self.customerNumber.append(customerNumber) def changeOnMailingList(): if onMailingList == False: onMailingList == True else: onMailingList == False def main(): customer1 = Customer() name = 'Bob Smith' address = '123 Somewhere Road' telephone = '111 222 3333' customerNumber = '12345' customer1.changeName(name) customer1.changeAddress(address) customer1.changeTelephone(telephone) customer1.changeCustomerNumber(customerNumber) print("Customer name: " + customer1.name) print("Customer address: " + customer1.address) print("Customer telephone number: " + customer1.telephone) print("Customer number: " + customer1.customerNumber) print("On mailing list: " + customer1.OnMailingList) customer1.changeOnMailingList() print("On mailing list: " + customer1.OnMailingList) main()

HTTP post using php and curl failing

I am trying to send an XML file to an external system. I am using the below code for doing so, which I got over the internet. But I observed that when i put an echo on the xml variable, it does not show me the XML as a string, but it is parsing the xml and showing me the values. Same is happening when I am sending this to external system. Which is failing. Can you please tell me a way, in which the XML is not parsed and I can send the entire XML text as a string to external system? My code is below. <?php $xml = '<?xml version=\"1.0\" encoding="UTF-8" ?><shiporder><orderID>1234</orderID> <orderperson>John Smith</orderperson></shiporder>'; $xml2 = ''; $headers = array( "Content-type: text/xml", "Content-length: " . strlen($xml), "Connection: close", ); // give the path of the Third party site $url = "http://<server>:<port>/XMII/Illuminator?service=WSMessageListener&mode=WSMessageListenerServer&NAME=shiporder&IllumLoginName=<name>&IllumLoginPassword=<pswd>"; echo $xml; echo $url; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL,$url); //curl_setopt($ch, CURLOPT_MUTE, 1); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_TIMEOUT, 10); curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); curl_setopt($ch, CURLOPT_POSTFIELDS, $xml); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $output = curl_exec($ch); echo $output; curl_close($ch); ?> Regards, Gita

Assistance with CC Processing script

- by JM4

I am currently implementing a credit card processing script, most as provided by the merchant gateway. The code calls functions within a class and returns a string based on the response. The end php code I am using (details removed of course) with example information is: <?php $gw = new gwapi; $gw->setLogin("username", "password"); $gw->setBilling("John","Smith","Acme, Inc.","888","Suite 200", "Beverly Hills", "CA","77777","US","555-555-5555","555-555-5556","[email protected]", "www.example.com"); // "CA","90210","US","[email protected]"); $gw->setOrder("1234","Big Order",1, 2, "PO1234","65.192.14.10"); $r = $gw->doSale("1.00","4111111111111111","1010"); print $gw->responses['responsetext']; ?> where setlogin allows me to login, setbilling takes the sample consumer information, set order takes the order id and description, dosale takes the amount charged, cc number and exp date. when all the variables are sent validated then sent off for processing, a string is returned in the following format: response=1&responsetext=SUCCESS&authcode=123456&transactionid=23456&avsresponse=M&orderid=&type=sale&response_code=100 where: response = transaction approved or declined response text = textual response authcode = transaction authorization code transactionid = payment gateway tran id avsresponse = avs response code orderid = original order id passed in tran request response_code = numeric mapping of processor response I am trying to solve for the following: How do I take the data which is passed back and display it appropriately on the page - If the transaction failed or AVS code doesnt match my liking or something is wrong, an error is displayed to the consumer; if the transaction processed, they are taken to a completion page and the transaction id is sent in SESSION as output to the consumer If the response_code value matches a table of values, certain actions are taken, i.e. if code =100, take to success page, if code = 300 print specific error on original page to customer, etc.

XNA Notes 009

This past week the MVPs (myself included) were on Microsoft campus for the MVP summit. So I apologize in advance if you did something cool or heard of something cool happening with XNA and XBLIGs and it’s not in my notes. I did my best to stay on top of things, but honestly this community is fast and furious with what it’s doing and creating. I really can’t keep up and that’s fantastic!

Visual Studio App.config XML Transformation

- by João Angelo

Visual Studio 2010 introduced a much-anticipated feature, Web configuration transformations. This feature allows to configure a web application project to transform the web.config file during deployment based on the current build configuration (Debug, Release, etc). If you haven’t already tried it there is a nice step-by-step introduction post to XML transformations on the Visual Web Developer Team Blog and for a quick reference on the supported syntax you have this MSDN entry. Unfortunately there are some bad news, this new feature is specific to web application projects since it resides in the Web Publishing Pipeline (WPP) and therefore is not officially supported in other project types like such as a Windows applications. The keyword here is officially because Vishal Joshi has a nice blog post on how to extend it’s support to app.config transformations. However, the proposed workaround requires that the build action for the app.config file be changed to Content instead of the default None. Also from the comments to the said post it also seems that the workaround will not work for a ClickOnce deployment. Working around this I tried to remove the build action change requirement and at the same time add ClickOnce support. This effort resulted in a single MSBuild project file (AppConfig.Transformation.targets) available for download from GitHub. It integrates itself in the build process so in order to add app.config transformation support to an existing Windows Application Project you just need to import this targets file after all the other import directives that already exist in the *.csproj file. Before – Without App.config transformation support ... <Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" /> <Target Name="BeforeBuild"> </Target> <Target Name="AfterBuild"> </Target> </Project> After – With App.config transformation support ... <Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" /> <Import Project="C:\MyExtensions\AppConfig.Transformation.targets" /> <Target Name="BeforeBuild"> </Target> <Target Name="AfterBuild"> </Target> </Project> As a final disclaimer, the testing time was limited so any problem that you find let me know. The MSBuild project invokes the mage tool so the Framework SDK must be installed. Update: I finally had some spare time and was able to check the problem reported by Geoff Smith and believe the problem is solved. The Publish command inside Visual Studio triggers a build workflow different than through MSBuild command line and this was causing problems. I posted a new version in GitHub that should now support ClickOnce deployment with app.config tranformation from within Visual Studio and MSBuild command line. Also here is a link for the sample application used to test the new version using the Publish command with the install location set to be from a CD-ROM or DVD-ROM and selected that the application will not check for updates. Thanks to Geoff for spotting the problem.

Sneak peek at next generation Three MiFi unit – Huawei E585

- by Liam Westley

Last Wednesday I was fortunate to be invited to a sneak preview of the next generation Three MiFi unit, the Huawei E585. Many thanks to all those who posted questions both via this blog or via @westleyl on Twitter. I think I made sure I asked every question posed to the MiFi product manager from Three UK, and so here's the answers you were after. What is a MiFi? For those who are wondering, a MiFi unit is a 3G broadband modem combined with a WiFi access point, providing 3G broadband data access to up to five devices simultaneously via standard WiFi connections. What is different? It appears the prime task of enhancing the MiFi was to improve the user experience and user interface, both in terms of the device hardware and within the management software to configure the device. I think this was a very sensible decision as these areas had substantial room for improvement. Single button operation to switch on, enable WiFi and connect to 3G Improved OELD display (see below), replacing the multi coloured LEDs; including signal strength, SMS notifications, the number of connected clients and data usage Management is via a web based dashboard accessible from any web browser. This is a big win for those running Linux, Mac OS/X, iPad users and, for me, as I can now configure the device from Windows 7 64-bit Charging is via micro USB, the new standard for small USB devices; you cannot use your old charger for the new MiFi unit Automatic reconnection when regaining a signal Improved charging time, which should allow recharging of the device when in use Although subjective, the black and silver design does look more classy than the silver and white plastic of the original MiFi What is the same? Virtually the same size and weight The battery is the same unit as the original MiFi so you’ll have a handy spare if you upgrade Data plans remain the same as the current MiFi, so cheapest price for upgraders will be £49 pay as you go Still only works on 3G networks, with no fallback to GPRS or EDGE There is no specific upgrade path for existing three customers, either from dongle or from the original MiFi My opinion I think three have concentrated on the correct areas of usability and user experience rather than trying to add new whizz bang technology features which aren’t of interest to mainstream users. The one button operation and the improved device display will make it much easier to use when out and about. If the automatic reconnection proves reliable that will remove a major bugbear that I experienced the previous evening when travelling on the First Great Western line from Paddington to Didcot Parkway. The signal was repeatedly lost as we sped through tunnels and cuttings, and without automatic reconnection is was a real pain to keep pressing the data button on the MiFi to re-establish my data connection. And finally, the web based dashboard will mean I no longer need to resort to my XP based netbook to configure the SSID and password. My everyday laptop runs Windows 7 64-bit which appears to confuse the older 3 WiFi manager which cannot locate the MiFi when connected. Links to other sites, and other images of the device Good first impressions from Ben Smith, http://thereallymobileproject.com/2010/06/3uk-announce-a-new-mifi-with-a-screen/ Also, a round up of other sneak preview posts, http://www.3mobilebuzz.com/2010/06/11/mifi-round-two-your-view/ Pictures Here is a comparison of the old MiFi device next to the new device, complete with OLED display and the Huawei logo now being a prominent feature on the front of the device. One of my fellow bloggers had a Linux based netbook, showing off the web based dashboard complete with Text messages panel to manage SMS. And finally, I never thought that my blog sub title would ever end up printed onto a cup cake, ... and here's some of the other cup cakes ...

SQLAuthority News – Professional Development and Community

- by pinaldave

I was recently invited by Hyderabad Techies to deliver a keynote for their 16-day online session called TECH THUNDERS. This event has been running from May 15 and will continue up to the end of the month May 30). There would be a total of 30 sessions. In every evening of those 16 day, there will be either one or two sessions from several noted industry experts. It is the same group which has received the Microsoft Community Impact Award as the Best User Group in India as for developers. I have never talked about Professional Development before. Even if this was my first time to do so, I still accepted the wonderful challenge for the sake of the thousands of audience who were expected to attend this online event. Time is of the essence; I had 15 minutes to deliver the keynote and open the event. The reason why I was nervous was because I had to cover precisely only 15 minutes- no more, no less. If I had an hour, I would have been very confident because I knew I could do a good job for sure. However, I still needed to open the event as great as it can be even if the time was short. I finally created a 6-slide small presentation. In reality, there were only two pages which had the main contents of my keynote, and the remaining slides were just wrappers and decors. You can download the complete slide deck from here. The image used in the slide deck is a curtsy of blog reader Roger Smith who sent it to me. The slide in which I spent a good amount of time is the slide which talks about Professional Development. The content of the slide is as follows: Today, Technology and You Keep your eyes, ears and senses open – Stay Active! You are not the first one who faced the problem – Search Online! Learn the web – Blogs, Forums and Friends! Trust the Technology, Not Print – Test Everything! Community and You! I had a very little time creating the slide deck as I was busy the whole day doing the Advanced SQL Server Training. I had put together these slides during the tea/coffee break of my session. Though it was just a six-bullet point, I had received quite a few emails right after keynote requesting me to talk more about this subject and share the details of my slide deck. I have talked with the event organizer and he will put the keynote online very soon. The subject of the talk is very simple; it revolves around the community. Time has changed, and Internet has come a long way from where it was many years ago. Now that we are all connected, help via the Internet and useful software is easily available around us. In fact, RSS, Newletters and few other technologies have progressed so much that the help through news is now being delivered to our door steps, instead of going out and seeking them. Sometimes, a simple search online solves a lot of problems of many developers. The community is now the first stop for any developer when he or she needs help or just wants to hang around and share some thoughts. I strongly suggest everybody to be a part of the Tech Community. Be it online, offline community or just a local user group, I strongly advise all of you to get involved. I am active in the Community, and I must say I recommend getting drawn into it.

Something for the weekend - Whats the most complex query?

- by simonsabin

Whenever I teach about SQL Server performance tuning I try can get across the message that there is no such thing as a table. Does that sound odd, well it isn't, trust me. Rather than tables you need to consider structures. You have 1. Heaps 2. Indexes (b-trees) Some people split indexes in two, clustered and non-clustered, this I feel confuses the situation as people associate clustered indexes with sorting, but don't associate non clustered indexes with sorting, this is wrong. Clustered and non-clustered indexes are the same b-tree structure(and even more so with SQL 2005) with the leaf pages sorted in a linked list according to the keys of the index.. The difference is that non clustered indexes include in their structure either, the clustered key(s), or the row identifier for the row in the table (see http://sqlblog.com/blogs/kalen_delaney/archive/2008/03/16/nonclustered-index-keys.aspx for more details). Beyond that they are the same, they have key columns which are stored on the root and intermediary pages, and included columns which are on the leaf level. The reason this is important is that this is how the optimiser sees the world, this means it can use any of these structures to resolve your query. Even if your query only accesses one table, the optimiser can access multiple structures to get your results. One commonly sees this with a non-clustered index scan and then a key lookup (clustered index seek), but importantly it's not restricted to just using one non-clustered index and the clustered index or heap, and that's the challenge for the weekend. So the challenge for the weekend is to produce the most complex single table query. For those clever bods amongst you that are thinking, great I will just use lots of xquery functions, sorry these are the rules. 1. You have to use a table from AdventureWorks (2005 or 2008) 2. You can add whatever indexes you like, but you must document these 3. You cannot use XQuery, Spatial, HierarchyId, Full Text or any open rowset function. 4. You can only reference your table once, i..e a FROM clause with ONE table and no JOINs 5. No Sub queries. The aim of this is to show how the optimiser can use multiple structures to build the results of a query and to also highlight why the optimiser is doing that. How many structures can you get the optimiser to use? As an example create these two indexes on AdventureWorks2008 create index IX_Person_Person on Person.Person (lastName, FirstName,NameStyle,PersonType) create index IX_Person_Person on Person.Person(BusinessentityId,ModifiedDate)with drop_existing select lastName, ModifiedDate from Person.Person where LastName = 'Smith' You will see that the optimiser has decided to not access the underlying clustered index of the table but to use two indexes above to resolve the query. This highlights how the optimiser considers all storage structures, clustered indexes, non clustered indexes and heaps when trying to resolve a query. So are you up to the challenge for the weekend to produce the most complex single table query? The prize is a pdf version of a popular SQL Server book, or a physical book if you live in the UK.

Configuring Fed Authentication Methods in OIF / IdP

- by Damien Carru

In this article, I will provide examples on how to configure OIF/IdP to map OAM Authentication Schemes to Federation Authentication Methods, based on the concepts introduced in my previous entry. I will show examples for the three protocols supported by OIF: SAML 2.0 SSO SAML 1.1 SSO OpenID 2.0 Enjoy the reading! Configuration As I mentioned in my previous article, mapping Federation Authentication Methods to OAM Authentication Schemes is protocol dependent, since the methods are defined in the various protocols (SAML 2.0, SAML 1.1, OpenID 2.0). As such, the WLST commands to set those mappings will involve: Either the SP Partner Profile and affect all Partners referencing that profile, which do not override the Federation Authentication Method to OAM Authentication Scheme mappings Or the SP Partner entry, which will only affect the SP Partner It is important to note that if an SP Partner is configured to define one or more Federation Authentication Method to OAM Authentication Scheme mappings, then all the mappings defined in the SP Partner Profile will be ignored. WLST Commands The two OIF WLST commands that can be used to define mapping Federation Authentication Methods to OAM Authentication Schemes are: addSPPartnerProfileAuthnMethod() to define a mapping on an SP Partner Profile, taking as parameters: The name of the SP Partner Profile The Federation Authentication Method The OAM Authentication Scheme name addSPPartnerAuthnMethod() to define a mapping on an SP Partner , taking as parameters: The name of the SP Partner The Federation Authentication Method The OAM Authentication Scheme name Note: I will discuss in a subsequent article the other parameters of those commands. In the next sections, I will show examples on how to use those methods: For SAML 2.0, I will configure the SP Partner Profile, that will apply all the mappings to SP Partners referencing this profile, unless they override mapping definition For SAML 1.1, I will configure the SP Partner. For OpenID 2.0, I will configure the SP/RP Partner SAML 2.0 Test Setup In this setup, OIF is acting as an IdP and is integrated with a remote SAML 2.0 SP partner identified by AcmeSP. In this test, I will perform Federation SSO with OIF/IdP configured to: Use LDAPScheme as the Authentication Scheme Use BasicScheme as the Authentication Scheme Map BasicSessionScheme to the urn:oasis:names:tc:SAML:2.0:ac:classes:Password Federation Authentication Method Use OAMLDAPPluginAuthnScheme as the Authentication Scheme Map OAMLDAPPluginAuthnScheme to the urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport Federation Authentication Method LDAPScheme as Authentication Scheme Using the OOTB settings regarding user authentication in OAM, the user will be challenged via a FORM based login page based on the LDAPScheme. Also the default Federation Authentication Method mappings configuration maps only the urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport to LDAPScheme (also marked as the default scheme used for authentication), FAAuthScheme, BasicScheme and BasicFAScheme. After authentication via FORM, OIF/IdP would issue an Assertion similar to: <samlp:Response ...> <saml:Issuer ...>https://idp.com/oam/fed</saml:Issuer> <samlp:Status> <samlp:StatusCode Value="urn:oasis:names:tc:SAML:2.0:status:Success"/> </samlp:Status> <saml:Assertion ...> <saml:Issuer ...>https://idp.com/oam/fed</saml:Issuer> <dsig:Signature> ... </dsig:Signature> <saml:Subject> <saml:NameID ...>[email protected]</saml:NameID> <saml:SubjectConfirmation Method="urn:oasis:names:tc:SAML:2.0:cm:bearer"> <saml:SubjectConfirmationData .../> </saml:SubjectConfirmation> </saml:Subject> <saml:Conditions ...> <saml:AudienceRestriction> <saml:Audience>https://acme.com/sp</saml:Audience> </saml:AudienceRestriction> </saml:Conditions> <saml:AuthnStatement AuthnInstant="2014-03-21T20:53:55Z" SessionIndex="id-6i-Dm0yB-HekG6cejktwcKIFMzYE8Yrmqwfd0azz" SessionNotOnOrAfter="2014-03-21T21:53:55Z"> <saml:AuthnContext> <saml:AuthnContextClassRef> urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport </saml:AuthnContextClassRef> </saml:AuthnContext> </saml:AuthnStatement> </saml:Assertion></samlp:Response> BasicScheme as Authentication Scheme For this test, I will switch the default Authentication Scheme for the SP Partner Profile to BasicScheme instead of LDAPScheme.

SQL SERVER – Merge Operations – Insert, Update, Delete in Single Execution

- by pinaldave

This blog post is written in response to T-SQL Tuesday hosted by Jorge Segarra (aka SQLChicken). I have been very active using these Merge operations in my development. However, I have found out from my consultancy work and friends that these amazing operations are not utilized by them most of the time. Here is my attempt to bring the necessity of using the Merge Operation to surface one more time. MERGE is a new feature that provides an efficient way to do multiple DML operations. In earlier versions of SQL Server, we had to write separate statements to INSERT, UPDATE, or DELETE data based on certain conditions; however, at present, by using the MERGE statement, we can include the logic of such data changes in one statement that even checks when the data is matched and then just update it, and similarly, when the data is unmatched, it is inserted. One of the most important advantages of MERGE statement is that the entire data are read and processed only once. In earlier versions, three different statements had to be written to process three different activities (INSERT, UPDATE or DELETE); however, by using MERGE statement, all the update activities can be done in one pass of database table. I have written about these Merge Operations earlier in my blog post over here SQL SERVER – 2008 – Introduction to Merge Statement – One Statement for INSERT, UPDATE, DELETE. I was asked by one of the readers that how do we know that this operator was doing everything in single pass and was not calling this Merge Operator multiple times. Let us run the same example which I have used earlier; I am listing the same here again for convenience. --Let’s create Student Details and StudentTotalMarks and inserted some records. USE tempdb GO CREATE TABLE StudentDetails ( StudentID INTEGER PRIMARY KEY, StudentName VARCHAR(15) ) GO INSERT INTO StudentDetails VALUES(1,'SMITH') INSERT INTO StudentDetails VALUES(2,'ALLEN') INSERT INTO StudentDetails VALUES(3,'JONES') INSERT INTO StudentDetails VALUES(4,'MARTIN') INSERT INTO StudentDetails VALUES(5,'JAMES') GO CREATE TABLE StudentTotalMarks ( StudentID INTEGER REFERENCES StudentDetails, StudentMarks INTEGER ) GO INSERT INTO StudentTotalMarks VALUES(1,230) INSERT INTO StudentTotalMarks VALUES(2,255) INSERT INTO StudentTotalMarks VALUES(3,200) GO -- Select from Table SELECT * FROM StudentDetails GO SELECT * FROM StudentTotalMarks GO -- Merge Statement MERGE StudentTotalMarks AS stm USING (SELECT StudentID,StudentName FROM StudentDetails) AS sd ON stm.StudentID = sd.StudentID WHEN MATCHED AND stm.StudentMarks > 250 THEN DELETE WHEN MATCHED THEN UPDATE SET stm.StudentMarks = stm.StudentMarks + 25 WHEN NOT MATCHED THEN INSERT(StudentID,StudentMarks) VALUES(sd.StudentID,25); GO -- Select from Table SELECT * FROM StudentDetails GO SELECT * FROM StudentTotalMarks GO -- Clean up DROP TABLE StudentDetails GO DROP TABLE StudentTotalMarks GO The Merge Join performs very well and the following result is obtained. Let us check the execution plan for the merge operator. You can click on following image to enlarge it. Let us evaluate the execution plan for the Table Merge Operator only. We can clearly see that the Number of Executions property suggests value 1. Which is quite clear that in a single PASS, the Merge Operation completes the operations of Insert, Update and Delete. I strongly suggest you all to use this operation, if possible, in your development. I have seen this operation implemented in many data warehousing applications.

Silverlight Cream for March 06, 2011 -- #1054

- by Dave Campbell

In this Back from the Summit Issue, I am overloaded with posts to choose from. Submittals go first, but I'll eventually catch up... hopefully by MIX :) : Ollie Riches(-2-), Colin Eberhardt, John Papa, Jeremy Likness, Martin Krüger, Joost van Schaik, Karl Shifflett, Michael Crump, Georgi Stoyanov, Yochay Kiriaty, Page Brooks, and Deborah Kurata. Above the Fold: Silverlight: "ClassifiedCabinet: A Quick Start" Georgi Stoyanov WP7: "Easy access to WMAppManifest.xml App properties like version and title" Joost van Schaik Multiple: "Flashcards.Show Version 2 for the Desktop, Browser, and Windows Phone" Yochay Kiriaty Shoutouts: Mohamed Mosallem delivered an online session at the Second Riyadh Online Community Summit: Silverlight 4.0 with SharePoint 2010 John-Daniel Trask posted about a release of a new set of tools released for WP7 development... there's a free trial, so definitely worth a look: Mindscape Phone Elements released! From SilverlightCream.com: WP7Contrib: Trickling data to a bound collection Ollie Riches submitted a couple links... first up is this on a way they found to decrease the load on a data template in WP7 to get under the 90 mb limit and then added their solution to the WP7Contrib lib. WP7Contrib: Why we use SilverlightSerializer instead of DataContractSerializer Ollie Riches' next submittal compares the performance of the SilverlightSerializer & DataContractSerializer on the WP7 platform. MVVM Charting – Binding Multiple Series to a Visiblox Chart Colin Eberhardt sent me this post where he describes binding multiple series to a chart with no code-behind... great long multi-phase tutorial all with source. Silverlight TV 64: Dive into 64bit Support, App Model and Security John Papa has Nick Kramer of the Silverlight team up for his latest Silverlight TV episode, discussing some cool new Silverlight stuff: 64-bit support, multiple windows, etc. Building a Windows Phone 7 Application with UltraLight.mvvm Jeremy Likness has a pre-summit tutorial up on his UltraLight.mvvm project, and how he would use it to build a WP7 app... great to meet you, Jeremy! How to: Storyboard only start with the conspicuousness of the application in the browser window Martin Krüger continues his Storyboard startup solutions with this one about what to do if the Silverlight app is small or simply an island on an html page. Easy access to WMAppManifest.xml App properties like version and title Joost van Schaik posted about the WP7 manifest file and how you can get access to that information at runtime... why you ask? How about version number or title? Be sure to read the helpful hints in the last paragraph too! Mole 2010 Released Karl Shifflett, Josh Smith, and others have released the latest version of Mole... well worth the money in my opinion, if only it worked for Silverlight! (not their fault) Changing the Default Windows Phone 7 Deployment Target In Visual Studio 2010 Michael Crump points out an annoyance with the 2011 WP7 tools update... VS2010 defaults to the device rather than the emulator... and he shows us how to get it pointed back to the emulator! ClassifiedCabinet: A Quick Start Georgi Stoyanov posted a QuickStart to a 'ClassifiedCabinet' control posted on CodePlex... check out the demo first, you'll want to read the article after that. He builds a simple project from scratch using the control. Flashcards.Show Version 2 for the Desktop, Browser, and Windows Phone Yochay Kiriaty has a post up about FlashCards.Show version 2 that he worked on with Arik Poznanski and has it now running on the desktop, browser, and WP7, plus you get the source... I've been wanting to write just such an app for WP7, so hey... this saves me some time! A Simple Focus Manager for Jounce Applications Page Brooks has a post up about Jeremy Likness' Jounce... how to set focus to a particular control when a view loads. Silverlight Charting: Formatting the Axis Deborah Kurata is continuing her charting series with this one on setting axis font color and putting the text at an angle... really dresses up the chart!
