  • What is the performance impact of tracing in C# and ASP.NET?

    - by SkippyFire
    I found this in some production login code I was looking at recently... HttpContext.Current.Trace.Write(query + ": " + username + ", " + password)); ...where query is a short SQL query to grab matching users. Does this have any sort of performance impact? I assume its very small. Also, what is the purpose of this exact type of trace, using the HTTP Context? Where does this data get traced to? Thanks in advance!

  • MySQL INSERT data does not get stored in proper db, only temporary?

    - by greye
    I'm having trouble with MySQL or Python and can't seem to isolate the problem. INSERTs only seem to last the run of the script and are not stored in the database. I have this script: import MySQLdb db = MySQLdb.connect(host="localhost", user="user", passwd="password", db="example") dbcursor = db.cursor() dbcursor.execute("select * from tablename") temp = dbcursor.fetchall() print 'before: '+str(temp) dbcursor.execute('INSERT INTO tablename (data1, data2, data3) VALUES ("1", "a", "b")') dbcursor.execute("select * from tablename") temp = dbcursor.fetchall() print 'after: '+str(temp) The first time I run it I get the expected output: >>> before: () after: ((1L, 'a', 'b'),) The problem is that if I run it again, the before comes out empty when it should already have the entry in it and the after doesn't break (data 1 is primary key). >>> before: () after: ((1L, 'a', 'b'),) >>> before: () after: ((1L, 'a', 'b'),) >>> before: () after: ((1L, 'a', 'b'),) If I try running the insert command twice in the same script it will break ("Duplicate entry for PRIMARY KEY") Any idea what might be happening here?

  • Dealing with personal failure

    - by codeelegance
    A while ago I was given the task of updating and extending the functionality of a software project. I was given a year to make the needed changes working solo. A month into development I came to the conclusion that it would take longer to change the existing product than to rewrite it from the ground up. I'd never attempted a complete rewrite so I talked with my boss about it and he was thrilled with the idea. I'm a fan of agile development but had never had the opportunity to take advantage of all of the prescribed practices so when I set to work I tried to incorporate as many as I could. I didn't have direct access to the customer and my coworkers (non-programmers) knew the business domain but were already so busy they didn't really have time to participate in design meetings so I resigned to working in the dark and occasionally calling one of them over to my desk to get feedback on my progress. I used TDD and refactored mercilessly and even tried taking a domain driven design approach. Things went well for a while. As the deadline came closer and the complexity of the project grew my productivity start slipping. I found myself cutting corners and ignoring the practices I had established as the pressure increased to meet the deadline. I also started working late nights and weekends to keep up with the load. In the end it made little difference how hard I worked. The project missed its deadline and what was completed wasn't enough to give to the customer. I had failed. Not only had I not finished on time but the previous version had sat untouched for almost a year so it wouldn't be of any help. Luckily we had another product that offered some of the same functionality. My boss decided to cancel the project entirely and moved all our orphaned customers to the other product. I spent weeks (along with everyone else at the company) manning the phones providing technical support for those customers. After it was all over, my boss was gracious enough not to fire me for nearly ruining the company. I was moved to the other product and have been trying to redeem myself ever since. Where did I go wrong? Has anyone else had to deal with this kind of defeat? How did you recover?

  • spring-nullpointerexception- cant access autowired annotated service (or dao) in a no-annotations class

    - by user286806
    I have this problem that I cannot fix. From my @Controller, i can easily access my autowired @Service class and play with it no problem. But when I do that from a separate class without annotations, it gives me a NullPointerException.

My separate Java class (not working)- public final class UsersManagementUtil { @Autowired UserService userService; or @Autowired UserDao userDao; userService or userDao are always null!

  • Converting LDAP from Tomcat to GlassFish

    - by Jon
    Hi, I have a simple web-app that is developed in Netbeans(6.8) and works fine in Tomcat(6) using LDAP(Active Directory). I need to convert this to an EE (JSF2), so I am moving from Tomcat to GlassFish(v3). I have changed the web files to xhtml and configured the xml files. However, I cannot get the GlassFish LDAP configuration to authenticate. I am attaching my old web.xml and server.xml (from Tomcat) snippets and the portions of the new web.xml, sun-web.xml, and the GlassFish configuration. If anyone can help me figure out where I am missing the piece that will allow a user to be authenticated, I would appreciate it. (btw, I am not using roles, just authenticating against the LDAP db is good enought.) As it is right now, my app will prompt me to enter a user when I try to access a file in the 'protected' area and the GlassFish server throws an exception when it fails to authenticate. Because it works under Tomcat, I know I have the right information, I just don't know how to format it to get GlassFish to pass it along. Thanks.

  • How to access GMAIL for storage in custom CRM SQL Server DB?

    - by Optimal Solutions
    I have a client who wants his custom-written CRM to be able to access his sales people's emails so that, effectively, a history of email conversations between customer and salesperson is stored inside the CRM's database. The CRM is written in VB 2008 and the database is SQL Server 2008. The only email these people use, in the shop and on the road, is GMAIL. Each sales person has their own GMAIL address. Thats how they operate. If they're on the road and respond to a customer's email inquiry about a product, they would like that email conversation to be stored in a table in the database. I think thats the part I cant wrap my head around. How to get access to the email data (knowing the user id and password) and doing so from VB 2008

  • What causes subprocess.call to output blank file when attempting db export with mysqldump?

    - by caldazar
    I am having some problems using subprocess.call to export a database using mysqldump. I'm using Python 3.1 installed on Windows 7. from time import gmtime, strftime import subprocess DumpDir = "c:/apps/sqlbackup/"; DumpFile = "mysqldump-" + strftime("%Y-%m-%d-%H-%M-%S", gmtime()) + ".sql"; params = [r"mysqldump --user root --password=mypassword --force --flush-privileges --compress --comments mydatabase --result-file=" + DumpDir + DumpFile]; subprocess.call(params, shell=True); The above code causes a blank file to be created in the DumpDir. I've tried getting python to print the command so I can test it via the CMD prompt using: print(subprocess.list2cmdline(params)); If I paste the output to the CMD prompt and execute it, everything works fine. Any ideas? I'm new to Python, so I am sure the answer is simple but I've tried so many variations to get this working that I just can't figure this out.

  • App logicstics & changes due to scope creep

    - by Kevin Brown
    I started an app that was initially a testing platform--user management, and managers that can view their employees tests. Recently, functionality has been extended (not built yet) to allow users to complete a test in place of an employee--basically adding a record, but no user. I have three tables in use for this: users(contains user info for login/security), profiles (all personal info: address, height, etc.), and survey (contains survey answers for user). How do I extend my application to encompass this functionality with minimal change to the structure? I assume that the best way to do this would be to insert records to the tables profiles and survey, and have no username/password/email? There MUST be a user_id associated b/c the tables are linked through the user_ids...

  • jQuery default/placeholder input text and problems with saved information

    - by user318106
    Hey Guys, I'm new to jQuery and have an annoying problem. I have some login fields that are filled with default text when the field is empty and then removed when clicked. My problem is that when the user has their username/password saved (with browser), if they return to the page the login fields are filled with the users saved input as well as the default input. $('#login input.text').each(function(i, field) { field = $(field); if (field.val().length 0) { field.prev().css('display', 'none'); } field.focus(function() { field.prev().css('display', 'none'); }).blur(function() { if (field.val() == '') field.prev().css('display', 'block'); }); })

  • How do API Keys and Secret Keys work?

    - by viatropos
    I am just starting to think about how api keys and secret keys work. Just 2 days ago I signed up for Amazon S3 and installed the S3Fox Plugin. They asked me for both my Access Key and Secret Access Key, both of which require me to login to access. So I'm wondering, if they're asking me for my secret key, they must be storing it somewhere right? Isn't that basically the same thing as asking me for my credit card numbers or password and storing that in their own database? How are secret keys and api keys supposed to work? How secret do they need to be? Are these applications that use the secret keys storing it somehow? Thanks for the insight.

  • A realistic and usable (VS2010) MVC2 project template?

    - by pomarc
    Hello. everybody. The default MVC2 web project template which VS2010 creates when you select "ASP.NET MVC2 Web Application" is quite a nice start... but nowhere near a realistic app framework. E.G.: user accounts without such features as password recover easily customizabile (and maybe multilingual) error messages an interface to manage users, such a searcheable user list, user edit and so on which an admin can use and these are just the beginning of the usual, mandatory basic features a web site of any size may use. Searching through the online projects templates doesn't seem to help, ehiter. Are there any project template sites or else that you are aware of, that gives such features? thanks a lot!

  • What keying option does the keychain use?

    - by Rudiger
    I have read into the keychain and have found that it uses Triple DES. What I can't find is what keying option it uses. I am guessing / hoping that its keying option 1 where all 3 passwords are unique but if thats the case I can only think of two passwords it can use (user password and App ID that comes from your dev cert) so where is the third coming from? Is it a key private to Apple? If its keying option 2 (first and third key are the same) it might not be secure enough for our company to rely on. Although that might sound paranoid I have to justify to our security department that it is secure enough.

  • Smart Client App: How to give Different Settings for Different Users

    - by Daniel
    Hi! I have a smart client application being deployed with a CickOnce webpage. here's the current scenario. User runs the application, and the application shows a login form. User enters ID/Password in the login form, and the application sends that information to the server. The server authenticates the user and sends configuration and data to the application. Different users have different configuration and data for their application. I was concerned that anyone can download the application from the webpage if they know the URL. So I'm trying to change the authentication scheme, so that users can login at the webpage to download the application. I want to send the authentication info from the webpage(Program running at the server) to the smart client app, so that application can download the configuration information from the server, without prompting users to make a login again. How can the webpage send the ID/Passoword to the application securely?

  • Writing a telnet client

    - by MAC
    HI, I have a device that exposes a telnet interface which you can log into using a username and password and then manipulate the working of the device. I have to write a C program that hides the telnet aspect from the client and instead provides an interface for the user to control the device. What would be a good way to proceed. I tried writing a simple socket program but it stops at the login prompt. My guess is that i am not following the TCP protocol. Has anyone attempted this, is there an opensource library out there to do this? Thanks

Examples (Pseudo-code) val splicedList:List[List[Int]]=biglist.partition(100) val sum:Int=ActorPool.numberOfActors(5).getAllResults(splicedList,foldLeft(_+_)) where spliceIntoParts turns one big list into 100 small lists the numberofactors part, creates a pool which uses 5 actors and receives new jobs after a job is finished and getallresults uses a method on a list. all this done with messages passing in the background. where maybe getFirstResult, calculates the first result, and stops all other threads (like cracking a password)
