• Encrypt correctly caracters in a PHP mail form ("I'm" turns to be "I\'m")

  - by Peanuts

  Hello guys, I'm testing a PHP mail form, a very barebones one, found here: <?php if(isset($_POST['submit'])) { //The form has been submitted, prep a nice thank you message $output = '<h3>Thanks for your message</h3>'; //Deal with the email $to = '[email protected]'; $subject = 'you have a mail'; $contactname = strip_tags($_POST['contactname']); $adress = strip_tags($_POST['adress']); $contactemail = strip_tags($_POST['contactemail']); $textmessage = strip_tags($_POST['textmessage']); $boundary =md5(date('r', time())); $headers = "From: My Site\r\nReply-To: [email protected]"; $message = "Name: ".$contactname."\n"; $message .= "Adress: ".$adress."\n"; $message .= "E-mail: ".$contactemail."\n"; $message .= "Message: ".$textmessage."\n"; mail($to, $subject, $message, $headers); } ?> The problem is I'm receiving an unwanted slash "\" everytime I write a single or a double quote in my message, so "I'm" appear as "I\'m" in my mailbox. I know it have to do with the way PHP distinguishes code quotes from only lecture quotes, but I wouldn't know what to add in my form to get it properly running. Any help is appreciated,

• Symfony generating database from model

  - by Sergej Jevsejev

  Hello, I am having troubles generating a simple database form model. I am using: Doctrine on Symfony 1.4.4 MySQL Workbench 5.2.16 with Doctrine Export 0.4.2dev So my ERL Model is: http://img708.imageshack.us/img708/1716/tmg.png Genereted YAML file: --- detect_relations: true options: collate: utf8_unicode_ci charset: utf8 type: InnoDB Course: columns: id: type: integer(4) primary: true notnull: true autoincrement: true name: type: string(255) notnull: true keywords: type: string(255) notnull: true summary: type: clob(65535) notnull: true Lecture: columns: id: type: integer(4) primary: true notnull: true autoincrement: true course_id: type: integer(4) primary: true notnull: true name: type: string(255) notnull: true description: type: string(255) notnull: true url: type: string(255) relations: Course: class: Course local: course_id foreign: id foreignAlias: Lectures foreignType: many owningSide: true User: columns: id: type: integer(4) primary: true unique: true notnull: true autoincrement: true firstName: type: string(255) notnull: true lastName: type: string(255) notnull: true email: type: string(255) unique: true notnull: true designation: type: string(1024) personalHeadline: type: string(1024) shortBio: type: clob(65535) UserCourse: tableName: user_has_course columns: user_id: type: integer(4) primary: true notnull: true course_id: type: integer(4) primary: true notnull: true relations: User: class: User local: user_id foreign: id foreignAlias: UserCourses foreignType: many owningSide: true Course: class: Course local: course_id foreign: id foreignAlias: UserCourses foreignType: many owningSide: true And no matter what I try this error occurs after: symfony doctrine:build --all --no-confirmation SQLSTATE[42000]: Syntax error or access violation: 1072 Key column 'user_userid' doesn't exist in table.

• Convert VBA to VBS

  - by dnLL

  I have a little VBA script with some functions that I would like to convert to a single VBS file. Here is an example of what I got: Private Declare Function GetPrivateProfileString Lib "kernel32" Alias "GetPrivateProfileStringA" (ByVal lpApplicationName As String, ByVal lpKeyName As Any, ByVal lpDefault As String, ByVal lpReturnedString As String, ByVal nSize As Long, ByVal lpFileName As String) As Long Private Function ReadIniFileString(ByVal Sect As String, ByVal Keyname As String) As String Dim Worked As Long Dim RetStr As String * 128 Dim StrSize As Long Dim iNoOfCharInIni As Integer Dim sIniString, sProfileString As String iNoOfCharInIni = 0 sIniString = "" If Sect = "" Or Keyname = "" Then MsgBox "Erreur lors de la lecture des paramètres dans " & IniFileName, vbExclamation, "INI" Access.Application.Quit Else sProfileString = "" RetStr = Space(128) StrSize = Len(RetStr) Worked = GetPrivateProfileString(Sect, Keyname, "", RetStr, StrSize, IniFileName) If Worked Then iNoOfCharInIni = Worked sIniString = Left$(RetStr, Worked) End If End If ReadIniFileString = sIniString End Function And then, I need to use this function to put some values in strings. VBS doesn't seem to like any of my var declaration ((Dim) MyVar As MyType). If I'm able to adapt that code to VBS, I should be able to do the rest of my functions too. How can I adapt/convert this to VBS? Thank you.

• Basic SQL Query, I am newbie

  - by user3530547

  I just started my database and query class on Monday. We met on Monday and just went over the syllabus, and on Wednesday the network at school was down so we couldn't even do the power point lecture. Right now I am working on my first homework assignment and I am almost finished but I am having trouble on one question. Here is is... Write a SELECT statement that returns one column from the Customers table named FullName that joins the LastName and FirstName columns. Format the columns with the last name, a comma, a space, and the first name like this: Doe, John Sort the result set by last name in ascending sequence. Return only the contacts whose last name begins with letters from M to Z. Here is what I have so far... USE md0577283 SELECT FirstName,LastName FROM Customers ORDER BY LastName,FirstName My question is how do I format is Lastname, FirstName like the professor wants and how do I only select names M-Z? If someone could point me in the right direction I would greatly appreciate it. Thank you. PS With all do respect, I didn't ask for the answer I asked for a nudge in the right direction so why the down vote guys?

• DDD North 3 Presentation and source code &ndash; &lsquo;Event Store - an introduction to a DSD for event sourcing and notifications&rsquo;

  - by Liam Westley

  Originally posted on: http://geekswithblogs.net/twickers/archive/2013/10/15/ddd-north-3-presentation-and-source-code-ndash-lsquoevent-store.aspxThank you everyone at DDD North Thanks to all the people who helped organise the cracking conference that is DDD North 3, returning to Sunderland, and the great facilities at the University of Sunderland, and the fine drinks reception at Sunderland Software City.  The whole event wouldn’t be possible without the sponsors who ensured over 400 people were kept fed and watered so they could enjoy the impressive range of sessions. And lastly, a thank you to all those delegates who gave up their free time on a Saturday to spend a day dashing between lecture rooms, including a late change to my room which saw 40 people having to brave a journey between buildings in the fine drizzle. The enthusiasm from the delegates always helps recharge my geek batteries. Presentation and source code My presentation, source code, Event Store runners and text files containing the various command line parameters used for curl is now available on GitHub; https://github.com/westleyl/DDDNorth3-EventStore. Don’t worry if you don’t have a GitHub account, you don’t need one, you can just click on the Download Zip button on the right hand menu to download all the files as a single ZIP file.  If all you want is the PowerPoint presentation, go to https://github.com/westleyl/DDDNorth3-EventStore/blob/master/Powerpoint/DDDNorth-EventStore.pptx, and click on the View Raw button. Downloading and installing Event Store and Tools Download Event Store http://download.geteventstore.com – I unzipped these files into C:\EventStore\v2.0.1 Download Curl from http://curl.haxx.se/download.html – I downloaded Win64 Generic (with SSL) and unzipped these files into C:\curl version 7.31.0 Running the tools I used in my presentation Demonstration 1 (running Event Store) You can use one of my Event Store runner command files to run the single node version of Event Store, using default ports of 2213 for HTTP and 1113  for TCP, and with a wildcard HTTP pattern.  Both take a single command line parameter to specify the location of the data and log files.  The runners assume the single node executable is located in C:\EventStore\v2.0.1, and will placed data files and logs beneath C:\EventStore\Data, i.e. RunEventStore.cmd TestData1 This will create data files in C:\EventStore\Data\TestData1\Data and log files in C:\EventStore\Data\TestData1\logs. If, when running Event Store you may see the following message, [03288,15,06:23:00.622] Failed to start http server Access is denied You will either need to run Event Store in an administrator console window, or you can use the netsh command to create a firewall permission to allow HTTP listening (this will need to be run, once, in an administrator console window), netsh http add urlacl url=http://*:2213/ user=liam You can always delete this later by running the delete; netsh http delete urlacl url=http://*:2213/ If you want to confirm that everything is running OK, open the management console in a browser by navigating to http://127.0.0.1:2213. If at any point you are asked for a user name and password use the default of ‘admin’/‘changeit’.   Demonstration 2 (reading and adding data, curl) In my second demonstration I used curl directly from the console to read streams, write events and then read back those events. On GitHub I have included is a set of curl commands, CurlCommandLine.txt, and a sample data file, SampleData.json, to load an event into a DDDNorth3 stream. As there is not much data in the Event Store at this point I used the $stats-127.0.0.1:2113 which is a stream containing performance statistics for Event Store and is updated every 30 seconds (default). Demonstration 3 (projections) On GitHub I have included a sample projection, Projection-ByRoom.txt, which will create streams based on the room on which a session was held on the DDDNorth3 agenda. Browse to the management console, http://127.0.0.1:2213.  Click on Projections, New Projection, give it a name, Sessions-ByRoom, and copy in the JavaScript in the Projection-ByRoom.txt file.  Select Continuous, tick Emit Enabled and then click on Post. It should run immediately. You may by challenged for the administration login for the management console, if so use the default user name and password; 'admin'/'changeit'.   Demonstration 4 (C# client) The final demonstration was the Visual Studio 2012 project using the Event Store client – referenced directly as C:\EventStore\v2.0.1\EventStore.ClientAPI.dll, although you can switch this to the latest Event Store client NuGet package. The source code provides a console app for viewing projections with the projection manager (HTTP connection), as well as containing a full set of data for the entire DDDNorth3 agenda.  It also deals with the strategy for reading newest events backwards to older events and ignoring older events that have been superseded. Resources Event Store home page: http://www.geteventstore.com/ Event Store source code on GitHub: https://github.com/eventstore/eventstore Event Store documentation on GitHub: https://github.com/eventstore/eventstore/wiki (includes index to @RobAshton’s blog series on Event Store at https://github.com/eventstore/eventstore/wiki#rob-ashton---projections-series) Event Store forum in Google Groups: https://groups.google.com/forum/?fromgroups#!forum/event-store TopShelf Windows service wrapper is available on github: https://gist.github.com/trbngr/5083266

• How to tell whether your programmers are under-performing?

  - by A Team Lead

  I am a team lead with 5+ developers. I have a developer (let's call him A) who is a good programmer, who writes good clean, easy to understand code. However he is somewhat difficult to manage, and sometimes I wonder whether he is really under-performing or not. Our company requires the developers to indicate the work progress in the bug tracker we use, not so much as to monitor the programmers but to let the stackholders know the progress. The thing is, A only updates a task progress when it is done ( maybe 3 weeks after it is first worked on) and this leaves everyone wondering what is going on in the middle of the development week. He wouldn't change his habit despite repeated probing. ( It's OK, developers hate paperwork, I do, too) Recent 2-3 months he on leave quite often due to various events-- either he is sick, or have to attend a lot of personal events etc. ( It's OK, bad things happen in a string. It's just a coincidence) We define sprints, or roadmaps for each month. And in the beginning of the sprint, we will discuss the amount of work each of the developers have to do in a sprint and the developers get to set the amount of time they need for each task. He usually won't be able to complete all of them. (It's OK, the developers are regularly missing deadlines not due to their fault). If only one or two of the above events happen, I won't feel that A is under-performing, but they all happen together. So I have the feeling that A is under-performing and maybe-- God forbid--- slacking off. This is just a feeling based on my years of experience as programmer. But I could be wrong. It is notoriously hard to measure the work of a programmer, given that not all two tasks are alike, and there lacks a standard objective to measure the commitment of a programmer to your company. It is downright impossible to tell whether the programmer is doing his job or slacking off. All you can do, is to trust them-- yeah, trusting and giving them autonomy is the best way for programmers to work, I know that, so don't start a lecture on why you need to trust your programmers, thank you every much-- but if they abuse your trust, can you know? My question is, how can you tell whether your programmers are under-performing? Surely there are experience team leads who know better than me on this? Outcome: I've a straight talk with him regarding my perception on his performance. He was indignant when I suggested that I had the feeling that he wasn't performing at his best level. He felt that this was a completely unfair feeling. I then replied that this was my feeling and I didn't know whether my feeling was right or not. He would have none of this and ended the discussion immediately. Before he left he said that he "would try to give more to the company" in a very cold tone. I was taken aback by his reaction. I am sure that I offended him in some ways. Not too sure whether that was the right thing to do for me to be so frank with him, though. Extra notes: I hate micromanaging. So all that we have for our software process is Sprint ( where tasks get prioritized and assigned, and at the end of the month, a review of the amount of work done). Developers would require to update the tasks as they go along everyday. There is no standup meeting, or anything of the sort. Mainly because we have the freedom to work from home and everyone cherishes this freedom. Although I am the one who sets the deadline, but the developers will provide the estimate for each tasks and I will decide-- based on the estimate-- the tasks that go into a particular sprint. If they can't finish the tasks at the end of the sprint, I will push them to the next. So theoretically one can just do only 1 or 2 tasks during the whole sprint and then push the remaining 99 tasks to the next sprint and still he will be fine as long as justifies this-- in the form of daily work progress updates

• Microsoft Sql Server 2008 R2 System Databases

  For a majority of software developers little time is spent understanding the inner workings of the database management systems (DBMS) they use to store data for their applications.  I personally place myself in this grouping. In my case, I have used various versions of Microsoft’s SQL Server (2000, 2005, and 2008 R2) and just recently learned how valuable they really are when I was preparing to deliver a lecture on "SQL Server 2008 R2, System Databases". Microsoft Sql Server 2008 R2 System DatabasesSo what are system databases in MS SQL Server, and why should I know them? Microsoft uses system databases to support the SQL Server DBMS, much like a developer uses config files or database tables to support an application. These system databases individually provide specific functionality that allows MS SQL Server to function. Name Database File Log File Master master.mdf mastlog.ldf Resource mssqlsystemresource.mdf mssqlsystemresource.ldf Model model.mdf modellog.ldf MSDB msdbdata.mdf msdblog.ldf Distribution distmdl.mdf distmdl.ldf TempDB tempdb.mdf templog.ldf Master DatabaseIf you have used MS SQL Server then you should recognize the Master database especially if you used the SQL Server Management Studio (SSMS) to connect to a user created database. MS SQL Server requires the Master database in order for DBMS to start due to the information that it stores. Examples of data stored in the Master database User Logins Linked Servers Configuration information Information on User Databases Resource DatabaseHonestly, until recently I never knew this database even existed until I started to research SQL Server system databases. The reason for this is due largely to the fact that the resource database is hidden to users. In fact, the database files are stored within the Binn folder instead of the standard MS SQL Server database folder path. This database contains all system objects that can be accessed by all other databases.  In short, this database contains all system views and store procedures that appear in all other user databases regarding system information. One of the many benefits to storing system views and store procedures in a single hidden database is the fact it improves upgrading a SQL Server database; not to mention that maintenance is decreased since only one code base has to be mainlined for all of the system views and procedures. Model DatabaseThe Model database as the name implies is the model for all new databases created by users. This allows for predefining default database objects for all new databases within a MS SQL Server instance. For example, if every database created by a user needs to have an “Audit” table when it is  created then defining the “Audit” table in the model will guarantees that the table will be located in every new database create after the model is altered. MSDB DatabaseThe MSDBdatabase is used by SQL Server Agent, SQL Server Database Mail, SQL Server Service Broker, along with SQL Server. The SQL Server Agent uses this database to store job configurations and SQL job schedules along with SQL Alerts, and Operators. In addition, this database also stores all SQL job parameters along with each job’s execution history.  Finally, this database is also used to store database backup and maintenance plans as well as details pertaining to SQL Log shipping if it is being used. Distribution DatabaseThe Distribution database is only used during replication and stores meta data and history information pertaining to the act of replication data. Furthermore, when transactional replication is used this database also stores information regarding each transaction. It is important to note that replication is not turned on by default in MS SQL Server and that the distribution database is hidden from SSMS. Tempdb DatabaseThe Tempdb as the name implies is used to store temporary data and data objects. Examples of this include temp tables and temp store procedures. It is important to note that when using this database all data and data objects are cleared from this database when SQL Server restarts. This database is also used by SQL Server when it is performing some internal operations. Typically, SQL Server uses this database for the purpose of large sort and index operations. Finally, this database is used to store row versions if row versioning or snapsot isolation transactions are being used by SQL Server. Additionally, I would love to hear from others about their experiences using system databases, tables, and objects in a real world environments.

• Javascript self contained sandbox events and client side stack

  - by amnon

  I'm in the process of moving a JSF heavy web application to a REST and mainly JS module application . I've watched "scalable javascript application architecture" by Nicholas Zakas on yui theater (excellent video) and implemented much of the talk with good success but i have some questions : I found the lecture a little confusing in regards to the relationship between modules and sandboxes , on one had to my understanding modules should not be effected by something happening outside of their sandbox and this is why they publish events via the sandbox (and not via the core as they do access the core for hiding base libary) but each module in the application gets a new sandbox ? , shouldn't the sandbox limit events to the modoules using it ? or should events be published cross page ? e.g. : if i have two editable tables but i want to contain each one in a different sandbox and it's events effect only the modules inside that sandbox something like messabe box per table which is a different module/widget how can i do that with sandbox per module , ofcourse i can prefix the events with the moduleid but that creates coupling that i want to avoid ... and i don't want to package modules toghter as one module per combination as i already have 6-7 modules ? while i can hide the base library for small things like id selector etc.. i would still like to use the base library for module dependencies and resource loading and use something like yui loader or dojo.require so in fact i'm hiding the base library but the modules themself are defined and loaded by the base library ... seems a little strange to me libraries don't return simple js objects but usualy wrap them e.g. : u can do something like $$('.classname').each(.. which cleans the code alot , it makes no sense to wrap the base and then in the module create a dependency for the base library by executing .each but not using those features makes a lot of code written which can be left out ... and implemnting that functionality is very bug prone does anyonen have any experience with building a front side stack of this order ? how easy is it to change a base library and/or have modules from different libraries , using yui datatable but doing form validation with dojo ... ? some what of a combination of 2+4 if u choose to do something like i said and load dojo form validation widgets for inputs via yui loader would that mean dojocore is a module and the form module is dependant on it ? Thanks .

• How should I ethically approach user password storage for later plaintext retrieval?

  - by Shane

  As I continue to build more and more websites and web applications I am often asked to store user's passwords in a way that they can be retrieved if/when the user has an issue (either to email a forgotten password link, walk them through over the phone, etc.) When I can I fight bitterly against this practice and I do a lot of ‘extra’ programming to make password resets and administrative assistance possible without storing their actual password. When I can’t fight it (or can’t win) then I always encode the password in some way so that it at least isn’t stored as plaintext in the database—though I am aware that if my DB gets hacked that it won’t take much for the culprit to crack the passwords as well—so that makes me uncomfortable. In a perfect world folks would update passwords frequently and not duplicate them across many different sites—unfortunately I know MANY people that have the same work/home/email/bank password, and have even freely given it to me when they need assistance. I don’t want to be the one responsible for their financial demise if my DB security procedures fail for some reason. Morally and ethically I feel responsible for protecting what can be, for some users, their livelihood even if they are treating it with much less respect. I am certain that there are many avenues to approach and arguments to be made for salting hashes and different encoding options, but is there a single ‘best practice’ when you have to store them? In almost all cases I am using PHP and MySQL if that makes any difference in the way I should handle the specifics. Additional Information for Bounty I want to clarify that I know this is not something you want to have to do and that in most cases refusal to do so is best. I am, however, not looking for a lecture on the merits of taking this approach I am looking for the best steps to take if you do take this approach. In a note below I made the point that websites geared largely toward the elderly, mentally challenged, or very young can become confusing for people when they are asked to perform a secure password recovery routine. Though we may find it simple and mundane in those cases some users need the extra assistance of either having a service tech help them into the system or having it emailed/displayed directly to them. In such systems the attrition rate from these demographics could hobble the application if users were not given this level of access assistance, so please answer with such a setup in mind. Thanks to Everyone This has been a fun questions with lots of debate and I have enjoyed it. In the end I selected an answer that both retains password security (I will not have to keep plain text or recoverable passwords), but also makes it possible for the user base I specified to log into a system without the major drawbacks I have found from normal password recovery. As always there were about 5 answers that I would like to have marked correct for different reasons, but I had to choose the best one--all the rest got a +1. Thanks everyone!

• Simplifying const Overloading?

  - by templatetypedef

  Hello all- I've been teaching a C++ programming class for many years now and one of the trickiest things to explain to students is const overloading. I commonly use the example of a vector-like class and its operator[] function: template <typename T> class Vector { public: T& operator[] (size_t index); const T& operator[] (size_t index) const; }; I have little to no trouble explaining why it is that two versions of the operator[] function are needed, but in trying to explain how to unify the two implementations together I often find myself wasting a lot of time with language arcana. The problem is that the only good, reliable way that I know how to implement one of these functions in terms of the other is with the const_cast/static_cast trick: template <typename T> const T& Vector<T>::operator[] (size_t index) const { /* ... your implementation here ... */ } template <typename T> T& Vector<T>::operator[] (size_t index) { return const_cast<T&>(static_cast<const Vector&>(*this)[index]); } The problem with this setup is that it's extremely tricky to explain and not at all intuitively obvious. When you explain it as "cast to const, then call the const version, then strip off constness" it's a little easier to understand, but the actual syntax is frightening,. Explaining what const_cast is, why it's appropriate here, and why it's almost universally inappropriate elsewhere usually takes me five to ten minutes of lecture time, and making sense of this whole expression often requires more effort than the difference between const T* and T* const. I feel that students need to know about const-overloading and how to do it without needlessly duplicating the code in the two functions, but this trick seems a bit excessive in an introductory C++ programming course. My question is this - is there a simpler way to implement const-overloaded functions in terms of one another? Or is there a simpler way of explaining this existing trick to students? Thanks so much!

• Microsoft TechEd 2010 - Day 3 @ Bangalore

  - by sathya

  Microsoft TechEd 2010 - Day 3 @ Bangalore Sorry for my delayed post on day 3 because I had to travel from Blore to Chennai So I couldnt write for the past two days. On day 3 as usual we had lot of simultaneous tracks on various sessions. This day I choose the Your Data, Our Platform Track. It had sessions on the following 5 topics :   Developing Data-tier Applications in Visual Studio 2010 - by Sanjay Nagamangalam SQL Server Query Optimization, Execution and Debugging Query Performance - by Vinod Kumar M SQL Server Utility - Its about more than 1 SQL Server - by Vinod Kumar Jagannathan Data Recovery / Consistency with CheckDB - by Vinod Kumar M Developing with SQL Server Spatial and Deep dive into Spatial Indexing - by Pinal Dave Developing Data-tier Applications in Visual Studio 2010 - by Sanjay Nagamangalam This was one of the superb sessions i have attended. He explained all the concepts in detail with a demo. The important thing in this is there is something called Data-Tier application project which is newly introduced in this VS2010 with which we can manage all our data along with our application inside our VS itself. We can create DB,Tables,Procs,Views etc. here itself and once we deploy it creates a compressed file called .dacpac which stores all the changes in Table Schema,Created procs, etc. on to that single file which reduces our (developer's) effort in preparing the deployment scripts and giving it to the DBA. It also has some policy configurations which can be managed easily by checking some rules like in outlook. For Ex : IF the SQL Server Version > 10 then deploy else dont. This rule specifies that even if we try to deploy on SQL Server DB with version less than 10 It will not do it. And if we deploy some .dacpac to SQL server production db with the option upgrade DB with this dacpac once everything completes successfully it will say success else it rollsback to the prior version. Even if it gets deployed successfully and later @ a point of time you wish to revert it back to the prior version, you can go ahead and delete the existing dacpac version so that it reverts to the older version of the db changes. And for the good questions that were asked in the session T-Shirts were given. SQL Server Query Optimization, Execution and Debugging Query Performance - by Vinod Kumar M This one too was the best session. The speaker Vinod explained everything very much clearly. This was really useful session and you dont believe, as per my knowledge, in the total 3 days in the TechEd except the Keynote, for this session seats were full (House FULL)  People were even standing out to attend this session. Such a great one it was. The speaker did a deep dive in to the Query Plan section and showed which actually causes the problem. Its all about the thing that we need to understand about the execution of SQL server Queries. We think in a way and SQL Server never executes in that way. We need to understand that first. He also told about there might be two plans generated for a single query at a point of time because of parallel processors in the system. The Key is here in every query. There is something called Estimated Row Count and Actual Row Count in the query plan. If the estimated row count by SQL server tallies with the actual row count your performance will be awesome. He said some tweaks to achieve the same. After this as usual we had lunch SQL Server Utility - Its about more than 1 SQL Server - by Vinod Kumar Jagannathan This was more of a DBA's session. Am really sorry I was totally blank and I was not interested to attend this session and walked out to attend Migrating to the cloud by Harish Ranganathan (My favorite Speaker) but unfortunately that was some other persons session. There the speaker was telling about how to configure the connection strings in such a way that we can connect to the SQL Azure platform from our VS and also showed us how to deploy the same in to Windows Azure. In between there were lot of technical problems like laptop hang, user locked and he was switching between systems, also i came in the half so i wasnt able to listen that fully. In between, Since I got an MCTS certification they gave me T-Shirt with the lines 'Iam Certified. Are you?' and they asked me to wear that. If we wear that we might get spotted and they would give us some goodies  So on the 3rd day I was wearing that T-Shirt. I got spotted by the person Tarun who was coordinating things about the certification, and he was accompanied with a cameraman and they interviewed me about the certification and I was shown live in the Teched and was seen by 60000 live viewers of the TechEd. I was really happy on that. Data Recovery / Consistency with CheckDB - by Vinod Kumar M This was one of the best sessions too in the TechEd. This guy is really amazing. In front of us he crashed a DB and showed how to recover the same in 6 different ways for different no of failures. Showed about Different types of error msgs like : 823,824,825 msdb..suspect_pages DBCC CheckDB (different parameters to it) I am really waiting for his session to get uploaded live in the Teched Website. Here is his contact info If you wish to connect to him : Twitter : @vinodk_sql Website : www.ExtremeExperts.com Blog : http://blogs.sqlxml.org/vinodkumar Developing with SQL Server Spatial and Deep dive into Spatial Indexing - by Pinal Dave Pinal Dave is a King in SQL and he is a SQL MVP and he is the owner of SQLAuthority.com He took the session on Spatial Databases from the start. Showed about the different types of Spatial : Geometric and Geographic Geometric : x and y axis its a planar surface Geographic : Spherical surface with 3600  as the maximum which is used to represent the geographic points on the earth and easy to draw maps of different kinds. He had a lot of obstacles during his session like rain coming inside the hall, mic wires got bursted due to rain, Videos off on the display screens. In spite of that he asked the audience to come in the front rows and managed to take a good session without ppts and finally we got the displays on and he was showing demos on the same what he explained orally. That was really a fun filled informative session. He gave some books for the persons who asked good questions and answered well for his questions and I got one too  (It was a book on Data Mining - Wrox Publishers) And finally after all these things there was Keynote session for close of the TechEd. and we all assembled in a big hall where Mr.Ashok Soota, a man of age around 70  co-founder of Mindtree was called to give some lecture on his successes. He was explaining about his past and what all companies he switched and for what reasons and what are all his successes and what are all his failures and the learnings of him from his past failures. and his success and failures on his partnerships with the other concern. And there were some questions for him like What is your suggestion on young entrepreneur? How did you learn from past failures? What is reiterating your success? What is your suggestion on partnerships? How to choose partnerships? etc. And they said @ 7.30 Pm there would be a party night, but unfortunately i was not able to attend that because I had to catch my train and before that i had to pack things, so I started @ 7 itself. Thats it about the TechED!!! Stay tuned for further Technology updates.

• Thoughts on Build 2013

  - by D'Arcy Lussier

  Originally posted on: http://geekswithblogs.net/dlussier/archive/2013/06/30/153294.aspxAnd so another Build conference has come to an end. Below are my thoughts/perspectives on various aspects of the event. I’ll do a separate blog post on my thoughts of the Build message for developers. The Good Moscone center was a great venue for Build! Easy to get around, easy to get to, and well maintained, it was a very comfortable conference venue. Yeah, the free swag was nice. Build has built up an expectation that attendees will always get something; it’ll be interesting to see how Microsoft maintains this expectation over the next few Build events. I still maintain that free swag should never be the main reason one attends an event, and for me this was definitely just an added bonus. I’m planning on trying to use the Surface as a dedicated 2nd device at work for meetings, I’ll share my experiences over the next few months. The hackathon event was a great idea, although personally I couldn’t justify spending the money on a conference registration just to spend the entire conference coding. Still, the apps that were created were really great and there was a lot of passion and excitement around the hackathon. I wonder if they couldn’t have had the hackathon on the Monday/Tuesday for those that wanted to participate so they didn’t miss any of the actual conference over Wed/Thurs. San Francisco was a great city to host Build. Getting from hotels to the conference center was very easy (well especially for me, I was only 3 blocks away) and the city itself felt very safe. However, if I never have to fly into SFO again I’ll be alright with that! Delays going into and out of SFO and both apparently were due to the airport itself. The Bad Build is one of those oddities on the conference landscape where people will pay to commit to attending an event without knowing anything about the sessions. We got our list of conference sessions when we registered on Tuesday, not before. And even then, we only got titles and not descriptions (those were eventually made available via the conference’s mobile application). I get it…they’re going to make announcements and they don’t want to give anything away through the session titles. But honestly, there wasn’t anything in the session titles that I would have considered a surprise. Breakfasts were brutal. High-carb pastries, donuts, and muffins with fruit and hard boiled eggs does not a conference breakfast make. I can’t believe that the difference between a continental breakfast per person and a hot breakfast buffet would have been a huge impact to a conference fee that was already around $2000. The vendor area was anemic. I don’t know why Microsoft forces the vendors into cookie-cutter booth areas (this year they were all made of plywood material). WPC, TechEd – booth areas there allow the vendors to be creative with their displays. Not so much for Build. Really odd was the lack of Microsoft’s own representation around Bing. In the day 1 keynote Microsoft made a big deal about Bing as an API. Yet there was nobody in the vendor area set up to provide more information or have discussions with about the Bing API. The Ugly Our name badges were NFC enabled. The purpose of this, beyond the vendors being able to scan your info, wasn’t really made clear. An attendee I talked to showed how you could get a reader app on your phone so you can scan other members cards and collect their contact info – which is a kewl idea; business cards are so 1990’s. But I was *shocked* at the amount of information that was on our name badges! Here’s what’s displayed on our name badge: - Name - Company - Twitter Handle I’m ok with that. But here’s what actually gets read: - Name - Company - Address Used for Registration - Phone Number Used for Registration So sharing that info with another attendee, they get way more of my info than just how to find me on Twitter! Microsoft, you need to fix this for the future. If vendors want to collect information on attendees, they should be able to collect an ID from the badge, then get a report with corresponding records afterwards. My personal information should not be so readily available, and without my knowledge! Final Verdict Maybe its my older age, maybe its where I’m at in life with family, maybe its where I’m at in my career, but when I consider whether a conference experience was valuable I get to the core reason I attend: opportunities to learn, opportunities to network, opportunities to engage with Microsoft. Opportunities to Learn:  Sessions I attended were generally OK, with some really stand out ones on Day 2. I would love to see Microsoft adopt the Dojo format for a portion of their sessions. Hands On Labs are dull, lecture style sessions are great for information sharing. But a guided hands-on coding session (Read: Dojo) provides the best of both worlds. Being that all content is publically available online to everyone (Build attendee or not), the value of attending the conference sessions is decreased. The value though is in the discussions that take part in person afterwards, which leads to… Opportunities to Network: I enjoyed getting together with old friends and connecting with Twitter friends in person for the first time. I also had an opportunity to meet total strangers. So from a networking perspective, Build was fantastic! I still think it would have been great to have an area for ad-hoc discussions – where speakers could announce they’d be available for more questions after their sessions, or attendees who wanted to discuss more in depth on a topic with other attendees could arrange space. Some people have no problems being outgoing and making these things happen, but others are not and a structured model is more attractive. Opportunities to Engage with Microsoft: Hit and miss on this one. Outside of the vendor area, unless you cornered or reached out to a speaker, there wasn’t any defined way to connect with blue badges. And as I mentioned above, Microsoft didn’t have full representation in the vendor area (no Bing). All in all, Build was a fun party where I was informed about some new stuff and got some free swag. Was it worth the time away from home and the hit to my PD budget? I’d say Somewhat. Build is a great informational conference, but I wouldn’t call it a learning conference. Considering that TechEd seems to be moving to more of an IT Pro focus, independent developer conferences seem to be the best value for those looking to learn and not just be informed. With the rapid development cycle Microsoft is embracing, we’re already seeing Build happening twice within a 12 month period. If that continues, the value of attending Build in person starts to diminish – especially with so much content available online. If Microsoft wants Build to be a must-attend event in the future, they need to start incorporating aspects of Tech Ed, past PDCs, and other conferences so those that want to leave with more than free swag have something to attract them.

• AsyncTask, inner classes and Buttons states

  - by Intern John Smith

  For a musical application (a sequencer), I have a few buttons static ArrayList<Button> Buttonlist = new ArrayList<Button>(); Buttonlist.add(0,(Button) findViewById(R.id.case_kick1)); Buttonlist.add(1,(Button) findViewById(R.id.case_kick2)); Buttonlist.add(2,(Button) findViewById(R.id.case_kick3)); Buttonlist.add(3,(Button) findViewById(R.id.case_kick4)); Buttonlist.add(4,(Button) findViewById(R.id.case_kick5)); Buttonlist.add(5,(Button) findViewById(R.id.case_kick6)); Buttonlist.add(6,(Button) findViewById(R.id.case_kick7)); Buttonlist.add(7,(Button) findViewById(R.id.case_kick8)); that I activate through onClickListeners with for example Buttonlist.get(0).setActivated(true); I played the activated sound via a loop and ifs : if (Buttonlist.get(k).isActivated()) {mSoundManager.playSound(1); Thread.sleep(250);} The app played fine but I couldn't access the play/pause button when it was playing : I searched and found out about AsyncTasks. I have a nested class PlayPause : class PlayPause extends AsyncTask<ArrayList<Button>,Integer,Void> in which I have this : protected Void doInBackground(ArrayList<Button>... params) { for(int k=0;k<8;k++) { boolean isPlayed = false; if (Buttonlist.get(k).isActivated()) { mSoundManager.playSound(1); isPlayed = true; try {Thread.sleep(250); } catch (InterruptedException e) {e.printStackTrace();}} if(!isPlayed){ try {Thread.sleep(250);} catch (InterruptedException e) {e.printStackTrace();} } } return null; } I launch it via Play.setOnClickListener(new PlayClickListener()); with PlayClickListener : public class PlayClickListener implements OnClickListener { private Tutorial acti; public PlayClickListener(){ super(); } @SuppressWarnings("unchecked") public void onClick(View v) { if(Tutorial.play==0){ Tutorial.play=1; Tutorial.Play.setBackgroundResource(R.drawable.action_down); acti = new Tutorial(); Tutorial.PlayPause myPlayPause = acti.new PlayPause(); myLecture.execute(Tutorial.Buttonlist); } else { Tutorial.play=0; Tutorial.lecture.cancel(true); Tutorial.Play.setBackgroundResource(R.drawable.action); } } } But it doesn't work. when I click on buttons and I touch Play/Pause, I have this : 07-02 11:06:01.350: E/AndroidRuntime(7883): FATAL EXCEPTION: AsyncTask #1 07-02 11:06:01.350: E/AndroidRuntime(7883): Caused by: java.lang.NullPointerException 07-02 11:06:01.350: E/AndroidRuntime(7883): at com.Tutorial.Tutorial$PlayPause.doInBackground(Tutorial.java:603) 07-02 11:06:01.350: E/AndroidRuntime(7883): at com.Tutorial.Tutorial$PlayPause.doInBackground(Tutorial.java:1) And I don't know how to get rid of this error. Obviously, the Asynctask doesn't find the Buttonlist activated status, even if the list is static. I don't know how to access these buttons' states, isPressed doesn't work either. Thanks for reading and helping me !

• Linux Kernel not upgraded (from Ubuntu 12.04 to 12.10) - can't remove old kernels and can't install new apps

  - by Tony Breyal

  Question: How do I remove old kernel images which refuse to be removed? Context: Yesterday I upgraded Ubuntu from 12.04 to 12.10. However, the linux kernel has not upgraded from 3.2 to 3.5 as I would have expected. $ uname -r 3.2.0-32-generic $ uname -a Linux tony-b 3.2.0-32-generic #51-Ubuntu SMP Wed Sep 26 21:33:09 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux $ cat /proc/version Linux version 3.2.0-32-generic (buildd@batsu) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) ) #51-Ubuntu SMP Wed Sep 26 21:33:09 UTC 2012 Not sure why that happened there. I wanted to install Audacity (v2.0.1-1_amd64) to edit a lecture audio file.

• Running a simple integration scenario using the Oracle Big Data Connectors on Hadoop/HDFS cluster

  - by hamsun

  Between the elephant ( the tradional image of the Hadoop framework) and the Oracle Iron Man (Big Data..) an english setter could be seen as the link to the right data Data, Data, Data, we are living in a world where data technology based on popular applications , search engines, Webservers, rich sms messages, email clients, weather forecasts and so on, have a predominant role in our life. More and more technologies are used to analyze/track our behavior, try to detect patterns, to propose us "the best/right user experience" from the Google Ad services, to Telco companies or large consumer sites (like Amazon:) ). The more we use all these technologies, the more we generate data, and thus there is a need of huge data marts and specific hardware/software servers (as the Exadata servers) in order to treat/analyze/understand the trends and offer new services to the users. Some of these "data feeds" are raw, unstructured data, and cannot be processed effectively by normal SQL queries. Large scale distributed processing was an emerging infrastructure need and the solution seemed to be the "collocation of compute nodes with the data", which in turn leaded to MapReduce parallel patterns and the development of the Hadoop framework, which is based on MapReduce and a distributed file system (HDFS) that runs on larger clusters of rather inexpensive servers. Several Oracle products are using the distributed / aggregation pattern for data calculation ( Coherence, NoSql, times ten ) so once that you are familiar with one of these technologies, lets says with coherence aggregators, you will find the whole Hadoop, MapReduce concept very similar. Oracle Big Data Appliance is based on the Cloudera Distribution (CDH), and the Oracle Big Data Connectors can be plugged on a Hadoop cluster running the CDH distribution or equivalent Hadoop clusters. In this paper, a "lab like" implementation of this concept is done on a single Linux X64 server, running an Oracle Database 11g Enterprise Edition Release 11.2.0.4.0, and a single node Apache hadoop-1.2.1 HDFS cluster, using the SQL connector for HDFS. The whole setup is fairly simple: Install on a Linux x64 server ( or virtual box appliance) an Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 server Get the Apache Hadoop distribution from: http://mir2.ovh.net/ftp.apache.org/dist/hadoop/common/hadoop-1.2.1. Get the Oracle Big Data Connectors from: http://www.oracle.com/technetwork/bdc/big-data-connectors/downloads/index.html?ssSourceSiteId=ocomen. Check the java version of your Linux server with the command: java -version java version "1.7.0_40" Java(TM) SE Runtime Environment (build 1.7.0_40-b43) Java HotSpot(TM) 64-Bit Server VM (build 24.0-b56, mixed mode) Decompress the hadoop hadoop-1.2.1.tar.gz file to /u01/hadoop-1.2.1 Modify your .bash_profile export HADOOP_HOME=/u01/hadoop-1.2.1 export PATH=$PATH:$HADOOP_HOME/bin export HIVE_HOME=/u01/hive-0.11.0 export PATH=$PATH:$HADOOP_HOME/bin:$HIVE_HOME/bin (also see my sample .bash_profile) Set up ssh trust for Hadoop process, this is a mandatory step, in our case we have to establish a "local trust" as will are using a single node configuration copy the new public keys to the list of authorized keys connect and test the ssh setup to your localhost: We will run a "pseudo-Hadoop cluster", in what is called "local standalone mode", all the Hadoop java components are running in one Java process, this is enough for our demo purposes. We need to "fine tune" some Hadoop configuration files, we have to go at our $HADOOP_HOME/conf, and modify the files: core-site.xml hdfs-site.xml mapred-site.xml check that the hadoop binaries are referenced correctly from the command line by executing: hadoop -version As Hadoop is managing our "clustered HDFS" file system we have to create "the mount point" and format it , the mount point will be declared to core-site.xml as: The layout under the /u01/hadoop-1.2.1/data will be created and used by other hadoop components (MapReduce = /mapred/...) HDFS is using the /dfs/... layout structure format the HDFS hadoop file system: Start the java components for the HDFS system As an additional check, you can use the GUI Hadoop browsers to check the content of your HDFS configurations: Once our HDFS Hadoop setup is done you can use the HDFS file system to store data ( big data : )), and plug them back and forth to Oracle Databases by the means of the Big Data Connectors ( which is the next configuration step). You can create / use a Hive db, but in our case we will make a simple integration of "raw data" , through the creation of an External Table to a local Oracle instance ( on the same Linux box, we run the Hadoop HDFS one node cluster and one Oracle DB). Download some public "big data", I use the site: http://france.meteofrance.com/france/observations, from where I can get *.csv files for my big data simulations :). Here is the data layout of my example file: Download the Big Data Connector from the OTN (oraosch-2.2.0.zip), unzip it to your local file system (see picture below) Modify your environment in order to access the connector libraries , and make the following test: [oracle@dg1 bin]$./hdfs_stream Usage: hdfs_stream locationFile [oracle@dg1 bin]$ Load the data to the Hadoop hdfs file system: hadoop fs -mkdir bgtest_data hadoop fs -put obsFrance.txt bgtest_data/obsFrance.txt hadoop fs -ls /user/oracle/bgtest_data/obsFrance.txt [oracle@dg1 bg-data-raw]$ hadoop fs -ls /user/oracle/bgtest_data/obsFrance.txt Found 1 items -rw-r--r-- 1 oracle supergroup 54103 2013-10-22 06:10 /user/oracle/bgtest_data/obsFrance.txt [oracle@dg1 bg-data-raw]$hadoop fs -ls hdfs:///user/oracle/bgtest_data/obsFrance.txt Found 1 items -rw-r--r-- 1 oracle supergroup 54103 2013-10-22 06:10 /user/oracle/bgtest_data/obsFrance.txt Check the content of the HDFS with the browser UI: Start the Oracle database, and run the following script in order to create the Oracle database user, the Oracle directories for the Oracle Big Data Connector (dg1 it’s my own db id replace accordingly yours): #!/bin/bash export ORAENV_ASK=NO export ORACLE_SID=dg1 . oraenv sqlplus /nolog <<EOF CONNECT / AS sysdba; CREATE OR REPLACE DIRECTORY osch_bin_path AS '/u01/orahdfs-2.2.0/bin'; CREATE USER BGUSER IDENTIFIED BY oracle; GRANT CREATE SESSION, CREATE TABLE TO BGUSER; GRANT EXECUTE ON sys.utl_file TO BGUSER; GRANT READ, EXECUTE ON DIRECTORY osch_bin_path TO BGUSER; CREATE OR REPLACE DIRECTORY BGT_LOG_DIR as '/u01/BG_TEST/logs'; GRANT READ, WRITE ON DIRECTORY BGT_LOG_DIR to BGUSER; CREATE OR REPLACE DIRECTORY BGT_DATA_DIR as '/u01/BG_TEST/data'; GRANT READ, WRITE ON DIRECTORY BGT_DATA_DIR to BGUSER; EOF Put the following in a file named t3.sh and make it executable, hadoop jar $OSCH_HOME/jlib/orahdfs.jar \ oracle.hadoop.exttab.ExternalTable \ -D oracle.hadoop.exttab.tableName=BGTEST_DP_XTAB \ -D oracle.hadoop.exttab.defaultDirectory=BGT_DATA_DIR \ -D oracle.hadoop.exttab.dataPaths="hdfs:///user/oracle/bgtest_data/obsFrance.txt" \ -D oracle.hadoop.exttab.columnCount=7 \ -D oracle.hadoop.connection.url=jdbc:oracle:thin:@//localhost:1521/dg1 \ -D oracle.hadoop.connection.user=BGUSER \ -D oracle.hadoop.exttab.printStackTrace=true \ -createTable --noexecute then test the creation fo the external table with it: [oracle@dg1 samples]$ ./t3.sh ./t3.sh: line 2: /u01/orahdfs-2.2.0: Is a directory Oracle SQL Connector for HDFS Release 2.2.0 - Production Copyright (c) 2011, 2013, Oracle and/or its affiliates.

• Hiding Options of a Select with JQuery

  - by Syed Abdul Rahman

  Okay, let's start with an example. Keep in mind, this is only an example. <select id = "selection1">     <option value = "1" id = "1">Number 1</option>     <option value = "2" id = "2">Number 2</option>     <option value = "3" id = "3">Number 3</option> </select> Now from here, we have a dropdown with 3 options. What I want to do now is to hide an option. Adding style = "display:none" will not help. The option would not appear in the dropdownlist, but using the arrow keys, you can still select it. Essentially, it does exactly what the code says. It isn't displayed, and it stops there. A JQuery function of $("#1").hide() will not work. Plus, I don't only want to hide the option, I want to completely remove it. Any possibility on doing so? Do I have to use parent/sibling/child elements? If so, I'm still not sure how. Any help on this would be greatly appreciated. Thanks.           Another question - It's related Ok, so I found out that there is a .remove() available in JQuery. Works well. But what if I want to bring it back? if(condition)     {     $(this).remove();     } I can loops this. Shouldn't be complicated. But the thing of which I am trying to do is this: Maximum Capacity of Class: (Input field here) Select Room: (Dropdown here) What I'd like for it to do is to update is Dropdown using a function such as .change() or .keyup. I could create the dropdown only after something is typed. At a change or a keyup, execute the dropdown accordingly. But what I am doing is this: $roomarray = mysql_query("SELECT *     FROM         (         SELECT *,         CASE         WHEN type = 'Classroom' THEN 1         WHEN type = 'Computer laboratory' THEN 2         WHEN type = 'Lecture Hall' THEN 3         WHEN type = 'Auditorium' THEN 4         END AS ClassTypeValue         FROM rooms         ) t     ORDER BY ClassTypeValue, maxppl, roomID"); echo "<select id = \"room\">"; while ($rooms = mysql_fetch_array($roomarray)) { ?> <option value=<?php echo $rooms['roomID']; ?> id=<?php echo $rooms['roomID']; ?>><?php echo $rooms['type']; echo "&nbsp;"; echo $rooms['roomID']; echo "&nbsp;("; echo $rooms['maxppl']; echo ")"; ?></option> <?php } echo "</select>"; Yes, I know it is very messy. I plan to change it later on. But the issue now is this: Can I toggle the removal of the options according to what has been typed? Is it possible to do so with a dropdown made from a loop? Because I sure as hell can't keep executing SQL Queries. Or is that even an option? Because if it's possible, I still think it's a bad one.

• HTML/jQuery/CSS Drop Down Menu Issue / Safari

  - by mmundiff

  I have a drop down menu that is coded in HTML, CSS, and jQuery and it works fine in Firefox and IE but not in Safari, and also not in Firefox on Mac. The drop down displays inline as opposed to list-item for the drop down in Safari. Any ideas why? <html> <head> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script> <script type="text/javascript" > $(document).ready(function(){ $('#menu li').hover( function() { //$('ul', this).css('display', 'block'); $('ul', this).fadeIn(200); var src = $('img.item', this).attr('src').match(/[^\.]+/) + '_over.png'; $('img.item', this).attr('src', src); }, function() { //$('ul', this).css('display', 'none'); $('ul', this).fadeOut(350); var src = $('img.item', this).attr('src').replace('_over', ''); $('img.item', this).attr('src', src); }); }); </script> <style type="text/css"> /* General */ body { arial, sans-serif; background-color: white; } * { padding: 0; margin: 0; } #menu{ white-space:nowrap; list-style:none; margin-left: 1px; } #menu ul { list-style: none; position:absolute; left:0; display:none; margin:0 -3px 0 -1px; padding:0; background: #000000; z-index: 500; margin-top: -4px; } #menu li{ display:inline; float: left; /* Added */ position:relative; } #menu li a { display: block; } #menu ul li { width:116px; float:left; border-top:1px dotted #666666; display: block; } #menu li ul { display: none; border-top: 1px black solid; text-align: left; } #menu ul a:hover { text-decoration:none; background: #efda83; color: #000000; } #menu ul a { text-decoration:none; display:block; height:15px; padding: 8px 5px; color:#efda83; font-size: 12px; } img{ border: 0 none; } .clear{ clear: both; } </style> </head> <body> <div> <ul id="menu"> <li ><a href="index.php"><img src="images/ssr_nav_home.png" class="item" alt="Home" /></a> </li> <li ><a href="about.php"><img src="images/ssr_nav_about.png" class="item" alt="About" /></a> <ul> <li><a href="about_contributors.php">Contributors</a></li> <li><a href="about_behind.php">Behind the Exhibit</a></li> <li><a href="about_sponsors.php">Sponsors</a></li> </ul> <div class="clear"></div> </li> <li ><a href="exhibit_intro.php"><img class="item" src="images/ssr_nav_exhibit.png" alt="Exhibit" /></a> <ul> <li><a href="exhibit_intro.php">Intro</a></li> <li><a href="exhibit_silkroad.php">Silk Road</a></li> <li><a href="exhibit_western_regions.php">Western Regions</a></li> <li><a href="exhibit_daily_life.php">Daily Life</a></li> <li><a href="exhibit_burial_practices.php">Burial Practices</a></li> <li><a href="exhibit_relevance.php">Relevance</a></li> </ul> <div class="clear"></div> </li> <li ><a href="visit.php"><img class="item" src="images/ssr_nav_visit.png" alt="Visit" /></a> <ul> <li><a href="visit_tickets.php">Tickets</a></li> <li><a href="visit_specials.php">Special Offers</a></li> <li><a href="visit_tours.php">Tours</a></li> <li><a href="visit_groups.php">Groups</a></li> </ul> <div class="clear"></div> </li> <li ><a href="events.php"><img class="item" src="images/ssr_nav_events.png" alt="Events" /></a> <ul> <li><a href="events_lectures.php">Lecture Series</a></li> <li><a href="events_symposium.php">Symposium</a></li> <li><a href="kids_and_family.php">Kids &amp; Family</a></li> <li><a href="events_calendar.php">Event Calendar</a></li> </ul> <div class="clear"></div> </li> <li ><a href="gallery.php"><img class="item" src="images/ssr_nav_images.png" alt="Gallery" /></a></li> <li ><a href="resources.php"><img class="item" src="images/ssr_nav_resources.png" alt="Resources" /></a> <ul> <li><a href="resources_teachers.php">For Teachers</a></li> <li><a href="kids_and_family.php">Kids &amp; Family</a></li> <li><a href="http://www.penn.museum/podcasts-and-videos/819-secrets-of-the-silk-road.html" rel="external">Podcasts &amp; Videos</a></li> <!-- <li><a href="map.php">Silk Road Map</a></li> <li><a href="resources_timeline.php">Timeline</a></li> --> <li><a href="resources_quiz.php">Quiz</a></li> <li><a href="glossary.php">Glossary</a></li> <li><a href="blogs.php">Blog</a></li> </ul> <div class="clear"></div> </li> <li ><a href="press.php"><img class="item" src="images/ssr_nav_press.png" alt="Press" /></a> <ul> <li><a href="press_release.php">Press Release</a></li> <li><a href="press_images.php">Press Images</a></li> <li><a href="press_bloggers.php">Bloggers</a></li> </ul> <div class="clear"></div> </li> </ul> </div> </body> </html>
