  • Ajax Form submittion in Google App Engine with jQuery

    - by user271785
    could not figure out why it is not working: i need to send request to server, generate some fragment of html in python with meanCal method, and then want that fragment embedded into submitting html file using calculation method and dynamically shows in dyContent div. all the processes are done by single click on submit button in a form. any suggestions??? thanks in advance. the submitting html: <div id="dyContent" style="height: 200px;"> waiting for user... {{ mgs }} </div> <div id="leturetext"> <form id="mean" method="post" action="/calculation"> <select name="meanselect"> <option value=10>example</option> <option value=11>exercise</option> </select> <input type="button" name="btnMean" value="Check Results" /> </form> </div> <script type="text/javascript"> $(document).ready(function() { //$("#btnMean").live("click", function() { $("#mean").submit(function(){ $.ajax({ type: "POST", cache: false, url: "/meanCal", success: function(html) { $("#dyContent").html(html); } }); return false; }); }); </script> python: class MainHandler(webapp.RequestHandler): def get(self): path = self.request.path if doRender(self, path): return doRender(self,'index.htm') class calculationHandler(webapp.RequestHandler): def post(self): doRender(self, 'Diagnostic_stats.htm', {'mgs' : "refreshed.", }) def get(self): doRender(self, 'Diagnostic_stats.htm') class meanHandler(webapp.RequestHandler): def get(self): global GL index = self.request.get('meanselect'.value) if (index == 10): allData = GL.exampleData dataString = ','.join(map(str, allData)) dataMean = (str)(stats.lmean(allData)) doRender(self, 'Result.htm', { 'dataIn' : dataString, 'MEAN' : "Example Mean is: " + dataMean, }) return else: allData = GL.exerciseData dataString = ','.join(map(str, allData)) dataMean = (str)(stats.lmean(allData)) doRender(self, 'Result.htm', { 'dataIn' : dataString, 'MEAN' : "Exercise Mean is: " + dataMean, }) def main(): global GL GL = GlobalVariables() application = webapp.WSGIApplication( [('/calculation', calculationHandler), ('/meanCal', meanHandler), ('.*', MainHandler), ], debug=True) wsgiref.handlers.CGIHandler().run(application) if __name__ == '__main__': main()

  • Asymptotic runtime of list-to-tree function

    - by Deestan
    I have a merge function which takes time O(log n) to combine two trees into one, and a listToTree function which converts an initial list of elements to singleton trees and repeatedly calls merge on each successive pair of trees until only one tree remains. Function signatures and relevant implementations are as follows: merge :: Tree a -> Tree a -> Tree a --// O(log n) where n is size of input trees singleton :: a -> Tree a --// O(1) empty :: Tree a --// O(1) listToTree :: [a] -> Tree a --// Supposedly O(n) listToTree = listToTreeR . (map singleton) listToTreeR :: [Tree a] -> Tree a listToTreeR [] = empty listToTreeR (x:[]) = x listToTreeR xs = listToTreeR (mergePairs xs) mergePairs :: [Tree a] -> [Tree a] mergePairs [] = [] mergePairs (x:[]) = [x] mergePairs (x:y:xs) = merge x y : mergePairs xs This is a slightly simplified version of exercise 3.3 in Purely Functional Data Structures by Chris Okasaki. According to the exercise, I shall now show that listToTree takes O(n) time. Which I can't. :-( There are trivially ceil(log n) recursive calls to listToTreeR, meaning ceil(log n) calls to mergePairs. The running time of mergePairs is dependent on the length of the list, and the sizes of the trees. The length of the list is 2^h-1, and the sizes of the trees are log(n/(2^h)), where h=log n is the first recursive step, and h=1 is the last recursive step. Each call to mergePairs thus takes time (2^h-1) * log(n/(2^h)) I'm having trouble taking this analysis any further. Can anyone give me a hint in the right direction?

  • Strange Access Denied warning when running the simplest C++ program.

    - by DaveJohnston
    I am just starting to learn C++ (coming from a Java background) and I have come across something that I can't explain. I am working through the C++ Primer book and doing the exercises. Every time I get to a new exercise I create a new .cpp file and set it up with the main method (and any includes I think I will need) e.g.: #include <list> #include <vector> int main(int argc, char **args) { } and just to make sure I go to the command prompt and compile and run: g++ whatever.cpp a.exe Normally this works just fine and I start working on the exercise, but I just did it and got a strange error. It compiles fine, but when I run it it says Access Denied and AVG pops up telling me that a threat has been detected 'Trojan Horse Generic 17.CKZT'. I tried compiling again using the Microsoft Compiler (cl.exe) and it runs fines. So I went back, and added: #include <iostream> compiled using g++ and ran. This time it worked fine. So can anyone tell me why AVG would report an empty main method as a trojan horse but if the iostream header is included it doesn't?

  • Finding Visio Shapes

    - by Julie Hurst
    Is there some way of printing out ALL Visio shapes - I used to manually do a screen shot of all the shapes and then print it out and bind it so I could flip through the pages and pick out shapes that I needed. Was really handy when I didnt know the name of a shape I was looking for. This exercise is now way too time consuming and was hoping there was some sort of gallery that I could scroll through that had ALL the shapes.

  • Integrated Help - Merged Help Indexes

    - by Rob Sanders
    If anyone has had more than a couple of Microsoft tools or products installed (or a local install of the MSDN library) side by side, you might have noticed that opening help (hitting F1) or opening, say, SQL Server Books Online causes the help indexes to be re-indexed - this is usually after installing a new product or tool. This can be a really, really time consuming exercise! Does anyone know a way to prevent or opt out of having combined help indexes? At best, even just preventing the reindexing at all?

  • MySQL keeps adding additional user without rights from specific IP

    - by Niels B.
    I'm running MySQL Server 5.5.29 on Ubuntu Server 13.04 I have a created a user with a wildcard host access % and given him various privileges. However, whenever this user connects from 194.182.245.61, a new user account is created for that specific IP address with no rights and he is unable to exercise his privileges. When he connects from other internet connections, such as his home IP, it works just as it should. Why does this happen and how can I stop it from happening?

  • SQL SERVER – 2008 – Introduction to Snapshot Database – Restore From Snapshot

    - by pinaldave
    Snapshot database is one of the most interesting concepts that I have used at some places recently. Here is a quick definition of the subject from Book On Line: A Database Snapshot is a read-only, static view of a database (the source database). Multiple snapshots can exist on a source database and can always reside on the same server instance as the database. Each database snapshot is consistent, in terms of transactions, with the source database as of the moment of the snapshot’s creation. A snapshot persists until it is explicitly dropped by the database owner. If you do not know how Snapshot database work, here is a quick note on the subject. However, please refer to the official description on Book-on-Line for accuracy. Snapshot database is a read-only database created from an original database called the “source database”. This database operates at page level. When Snapshot database is created, it is produced on sparse files; in fact, it does not occupy any space (or occupies very little space) in the Operating System. When any data page is modified in the source database, that data page is copied to Snapshot database, making the sparse file size increases. When an unmodified data page is read in the Snapshot database, it actually reads the pages of the original database. In other words, the changes that happen in the source database are reflected in the Snapshot database. Let us see a simple example of Snapshot. In the following exercise, we will do a few operations. Please note that this script is for demo purposes only- there are a few considerations of CPU, DISK I/O and memory, which will be discussed in the future posts. Create Snapshot Delete Data from Original DB Restore Data from Snapshot First, let us create the first Snapshot database and observe the sparse file details. USE master GO -- Create Regular Database CREATE DATABASE RegularDB GO USE RegularDB GO -- Populate Regular Database with Sample Table CREATE TABLE FirstTable (ID INT, Value VARCHAR(10)) INSERT INTO FirstTable VALUES(1, 'First'); INSERT INTO FirstTable VALUES(2, 'Second'); INSERT INTO FirstTable VALUES(3, 'Third'); GO -- Create Snapshot Database CREATE DATABASE SnapshotDB ON (Name ='RegularDB', FileName='c:\SSDB.ss1') AS SNAPSHOT OF RegularDB; GO -- Select from Regular and Snapshot Database SELECT * FROM RegularDB.dbo.FirstTable; SELECT * FROM SnapshotDB.dbo.FirstTable; GO Now let us see the resultset for the same. Now let us do delete something from the Original DB and check the same details we checked before. -- Delete from Regular Database DELETE FROM RegularDB.dbo.FirstTable; GO -- Select from Regular and Snapshot Database SELECT * FROM RegularDB.dbo.FirstTable; SELECT * FROM SnapshotDB.dbo.FirstTable; GO When we check the details of sparse file created by Snapshot database, we will find some interesting details. The details of Regular DB remain the same. It clearly shows that when we delete data from Regular/Source DB, it copies the data pages to Snapshot database. This is the reason why the size of the snapshot DB is increased. Now let us take this small exercise to  the next level and restore our deleted data from Snapshot DB to Original Source DB. -- Restore Data from Snapshot Database USE master GO RESTORE DATABASE RegularDB FROM DATABASE_SNAPSHOT = 'SnapshotDB'; GO -- Select from Regular and Snapshot Database SELECT * FROM RegularDB.dbo.FirstTable; SELECT * FROM SnapshotDB.dbo.FirstTable; GO -- Clean up DROP DATABASE [SnapshotDB]; DROP DATABASE [RegularDB]; GO Now let us check the details of the select statement and we can see that we are successful able to restore the database from Snapshot Database. We can clearly see that this is a very useful feature in case you would encounter a good business that needs it. I would like to request the readers to suggest more details if they are using this feature in their business. Also, let me know if you think it can be potentially used to achieve any tasks. Complete Script of the afore- mentioned operation for easy reference is as follows: USE master GO -- Create Regular Database CREATE DATABASE RegularDB GO USE RegularDB GO -- Populate Regular Database with Sample Table CREATE TABLE FirstTable (ID INT, Value VARCHAR(10)) INSERT INTO FirstTable VALUES(1, 'First'); INSERT INTO FirstTable VALUES(2, 'Second'); INSERT INTO FirstTable VALUES(3, 'Third'); GO -- Create Snapshot Database CREATE DATABASE SnapshotDB ON (Name ='RegularDB', FileName='c:\SSDB.ss1') AS SNAPSHOT OF RegularDB; GO -- Select from Regular and Snapshot Database SELECT * FROM RegularDB.dbo.FirstTable; SELECT * FROM SnapshotDB.dbo.FirstTable; GO -- Delete from Regular Database DELETE FROM RegularDB.dbo.FirstTable; GO -- Select from Regular and Snapshot Database SELECT * FROM RegularDB.dbo.FirstTable; SELECT * FROM SnapshotDB.dbo.FirstTable; GO -- Restore Data from Snapshot Database USE master GO RESTORE DATABASE RegularDB FROM DATABASE_SNAPSHOT = 'SnapshotDB'; GO -- Select from Regular and Snapshot Database SELECT * FROM RegularDB.dbo.FirstTable; SELECT * FROM SnapshotDB.dbo.FirstTable; GO -- Clean up DROP DATABASE [SnapshotDB]; DROP DATABASE [RegularDB]; GO Reference : Pinal Dave (http://blog.SQLAuthority.com) Filed under: SQL, SQL Authority, SQL Backup and Restore, SQL Data Storage, SQL Query, SQL Server, SQL Tips and Tricks, SQLServer, T SQL, Technology

  • Unity AddExplosionForce not doing anything

    - by Zero
    Recently I've started learning Unity3D. I'm working on a game as an exercise in which you control a space ship and have to dodge asteroids. If you feel like it's getting a bit too much you can hit the space bar, emitting a blast in all directions that repulses nearby asteroids. To create this blast I have the following code: public class PlayerBlastScript : MonoBehaviour { public ParticleSystem BlastEffect; // Update is called once per frame void Update () { if (Input.GetKeyUp(KeyCode.Space)) { Fire(); } } public void Fire() { ParticleEmitter effect = (ParticleEmitter) Instantiate (BlastEffect, transform.position, Quaternion.identity); effect.Emit(); Vector3 explosionPos = transform.position; Collider[] colliders = Physics.OverlapSphere(explosionPos, 25.0f); foreach(Collider hit in colliders) { if (!hit) { continue; } if (hit.rigidbody) { hit.rigidbody.AddExplosionForce(5000.0f, explosionPos, 100.0f); } } } } Even though the blast effect appears, the asteroids are not affected at all. The asteroids are all rigid bodies so what's the problem?

  • Unit testing is… well, flawed.

    - by Dewald Galjaard
    Hey someone had to say it. I clearly recall my first IT job. I was appointed Systems Co-coordinator for a leading South African retailer at store level. Don’t get me wrong, there is absolutely nothing wrong with an honest day’s labor and in fact I highly recommend it, however I’m obliged to refer to the designation cautiously; in reality all I had to do was monitor in-store prices and two UNIX front line controllers. If anything went wrong – I only had to phone it in… Luckily that wasn’t all I did. My duties extended to some other interesting annual occurrence – stock take. Despite a bit more curious affair, it was still a tedious process that took weeks of preparation and several nights to complete.  Then also I remember that no matter how elaborate our planning was, the entire exercise would be rendered useless if we couldn’t get the basics right – that being the act of counting. Sounds simple right? We’ll with a store which could potentially carry over tens of thousands of different items… we’ll let’s just say I believe that’s when I first became a coffee addict. In those days the act of counting stock was a very humble process. Nothing like we have today. A staff member would be assigned a bin or shelve filled with items he or she had to sort then count. Thereafter they had to record their findings on a complementary piece of paper. Every night I would manage several teams. Each team was divided into two groups - counters and auditors. Both groups had the same task, only auditors followed shortly on the heels of the counters, recounting stock levels, making sure the original count correspond to their findings. It was a simple yet hugely responsible orchestration of people and thankfully there was one fundamental and golden rule I could always abide by to ensure things run smoothly – No-one was allowed to audit their own work. Nope, not even on nights when I didn’t have enough staff available. This meant I too at times had to get up there and get counting, or have the audit stand over until the next evening. The reason for this was obvious - late at night and with so much to do we were prone to make some mistakes, then on the recount, without a fresh set of eyes, you were likely to repeat the offence. Now years later this rule or guideline still holds true as we develop software (as far removed as software development from counting stock may be). For some reason it is a fundamental guideline we’re simply ignorant of. We write our code, we write our tests and thus commit the same horrendous offence. Yes, the procedure of writing unit tests as practiced in most development houses today – is flawed. Most if not all of the tests we write today exercise application logic – our logic. They are based on the way we believe an application or method should/may/will behave or function. As we write our tests, our unit tests mirror our best understanding of the inner workings of our application code. Unfortunately these tests will therefore also include (or be unaware of) any imperfections and errors on our part. If your logic is flawed as you write your initial code, chances are, without a fresh set of eyes, you will commit the same error second time around too. Not even experience seems to be a suitable solution. It certainly helps to have deeper insight, but is that really the answer we should be looking for? Is that really failsafe? What about code review? Code review is certainly an answer. You could have one developer coding away and another (or team) making sure the logic is sound. The practice however has its obvious drawbacks. Firstly and mainly it is resource intensive and from what I’ve seen in most development houses, given heavy deadlines, this guideline is seldom adhered to. Hardly ever do we have the resources, money or time readily available. So what other options are out there? A quest to find some solution revealed a project by Microsoft Research called PEX. PEX is a framework which creates several test scenarios for each method or class you write, automatically. Think of it as your own personal auditor. Within a few clicks the framework will auto generate several unit tests for a given class or method and save them to a single project. PEX help to audit your work. It lends a fresh set of eyes to any project you’re working on and best of all; it is cost effective and fast. Check them out at http://research.microsoft.com/en-us/projects/pex/ In upcoming posts we’ll dive deeper into how it works and how it can help you.   Certainly there are more similar frameworks out there and I would love to hear from you. Please share your experiences and insights.

  • No VB6 to VS2010 direct upgrade path

    - by Chris Williams
    From the "is this really news?" department... From looking at the currently available versions of 2010, there is no direct upgrade path from VB6 to VS2010. Anyone still using VB6 and wishing to upgrade to VS2010 has two options:  Use the upgrade tool from an earlier version of VS (like 2005 or 2008) and then run the upgrade in VS2010 to get the rest of the way... or rewrite your code. I'll leave it as an exercise to the reader which is the better option. I'd like to take a moment to point out the obvious: A) If you're still using VB6 at this point, you probably don't care about VS2010 compatibility. B) Running your code through 2 upgrade wizards isn't going to result in anything resembling best practices. C) Bemoaning the lack of support in 2010 for a 12 year old version of an extinct programming language helps nobody. This public service announcement is brought to you by the letter C. Thank you.

  • Getting a solid understanding of Linux fundamentals

    - by JoshEarl
    I'm delving into the Linux world again as a diversion from my Microsoft-centric day job, and every time I tackle a new project I find it a frustrating exercise in trial and error. One thing that I always try to do when learning something new is figure out what the big pieces are and how they work together. I haven't yet come across a resource that explains Linux at this level. Resources seem to be either aimed at the barely computer literate crowd (Linux doesn't bite. Promise!) or the just compile the kernel and make your own distro crowd. I'm looking for a "JavaScript: The Good Parts" type of road map that doesn't necessarily answer all my questions so much as help me understand what questions I need to be asking. Any suggestions?

  • Keyring Password, Unity in 11.10

    - by Collin Owens
    Login to 11.10 I input my password and shortly afterward I am asked for a keyring password. I realize that I was asked for this during installation (second time lucky!) and I did enter a password (what a mistaka to maka). This now entails my having to input the keyring password on every boot up! Looking at previous answers it would seem that the applications - accesories - password and encryption keys - was the suggested route. However I assume that was in Gnome (At this stage I look back in fondness!!!) Certainly, I don't get the same route in Unity! I saw a reference to seahorse in a terminal - but this results in several error reports and a sub windows which does not seem to open. The objective in this exercise is to log in using the login password and not also the keyring password! any help would be appreciated - thank you

  • Embarking on a website redevelopment and all developers pushing to move to ASP.NET 4.0

    - by Sue
    Our company is going through a website redevelopment / retooling exercise and we are not quite sure which direction to take. We are told that the website was built in ASP classic and that we should be moving to ASP.NET 4.0. Some developers refuse to do any work in the ASP classic framework citing the advantages of ASP.NET 4.0-- stability, compilation, language support. We are generally happy with our website as is. There are some kinks in the backend involving forms and there is little integration between the CRM of the website and any content management system. Does the move from ASP classic to ASP.NET 4.0 give major advantages to the integration between how content is created, and delivered to our customers?

  • How to use multiple monitors effectivelly

    - by maaartinus
    I'm currently using a single monitor, since I see no value in something like this mentioned in this answer. It may be a good exercise for my neck, but besides of this I see no use therein at all. This amounts to 5760x1200 pixels, which is nearly 7M pixels, just fantastic, except for me not being a cyklop-han. The ratio of 24:5 is IMHO too bad for this to be usable. I don't even think that two 16:10 monitors side by side is a good idea. I never tried so I may be completely wrong, but I suppose that the 4:3 ratio would be much better for this. Or even 1:1, but no such thing is available (with some exceptions, either very expensive or very low resolution). Does anybody use two monitors arranged vertically (resulting in 16:20)? or two pivoted monitors side by side (resulting in 20:16)? or another such variant?

  • Physical effects of long term keyboard use- what does the science say and what factors affect it?

    - by glenatron
    This question asks about the ergonomics of a particular keyboard for long programming hours, what I would like to know is about the ergonomics of using a keyboard in general. What are the most significant risks associated with it and how can they best be mitigated? Do the "ergonomic" keyboard designs make a difference and if so which design is most effective? If not do other factors such as wrist-rests, regular exercise or having a suitable height of chair or desk make a difference? Do you have any direct experience of problems deriving from keyboard use and if so how did you resolve them? Is there any good science on this and if so what does it indicate? Edited to add: Wikipedia suggests that there are no proven advantages to "ergonomic" keyboards, but their citation seems pretty old- is that still the current state of play?

  • ING: Scaling Role Management and Access Certification to Thousands of Applications

    - by Tanu Sood
    Organizations deal with employee and user access certifications in different ways.  There’s collation of multiple spreadsheets, an intense two-week exercise by managers or use of access certification tools to do so across a handful of applications. But for most organizations compliance is about certifying user access for thousands of employees across hundreds of systems. Managing and auditing millions of entitlement combinations on a periodic basis poses a huge scale challenge. ING solved the compliance scale challenge using an Identity Platform approach. Join the live webcast featuring ING’s enterprise architect, Mark Robison, as he discusses how a platform approach offers value that is greater than the sum of its parts and enables ING to successfully meet their security and compliance goals. Mark will also share his implementation experiences and discuss the key requirements to manage the complexity and scale of access certification efforts at ING. Mark will be joined by Neil Gandhi, Principal Product Manager for Oracle Identity Analytics.

    I got this question in an interview and I was not able to solve it. You have a circular road, with N number of gas stations. You know the ammount of gas that each station has. You know the ammount of gas you need to GO from one station to the next one. Your car starts with 0. The question is: Create an algorithm, to know from which gas station you must start driving. As an exercise to me, I would translate the algorithm to C#.

  • Books or help on OO Analysis

    - by Pat
    I have this course where we learn about the domain model, use cases, contracts and eventually leap into class diagrams and sequence diagrams to define good software classes. I just had an exam and I got trashed, but part of the reason is we barely have any practical material, I spent at least two good months without drawing a single class diagram by myself from a case study. I'm not here to blame the system or the class I'm in, I'm just wondering if people have some exercise-style books that either provide domain models with glossaries, system sequence diagrams and ask you to use GRASP to make software classes? I could really use some alone-time practicing going from analysis to conception of software entities. I'm almost done with Larman's book called "Applying UML and Patterns An Introduction to Object-Oriented Analysis and Design and Iterative Development, Third Edition". It's a good book, but I'm not doing anything by myself since it doesn't come with exercises. Thanks.

  • Where can I get a list of PDF viewer/form-filler components for C#? [closed]

    - by Volomike
    Where can I get a list of recommended PDF viewer and form-filler components that I can buy and install in C#? I query on C# component PDF viewer on Google and get a lot of hits, but I'm not certain what programmers have tried and liked. Background: See, my employer is wanting me to build one in C# as a kind of training exercise, but also to be a product for sales lead generation for another product they sell. The employer is perfectly okay buying something, as long as it's good. I've learned VB6 and PHP, and know a little C and C++, so I'm trying to learn where people get the best-rated addon components for it, and especially for this PDF viewer and form filler thing he wants.

  • What's the most effective way to perform code reviews?

    - by Paddyslacker
    I've never found the ideal way to perform code reviews and yet often my customers require them. Each customer seems to do them in a different way and I've never felt satisfied in any of them. What has been the most effective way for you to perform code reviews? For example: Is one person regarded as the gatekeeper for quality and reviews the code, or do the team own the standard? Do you do review code as a team exercise using a projector? Is it done in person, via email or using a tool? Do you eschew reviews and use things like pair programming and collective code ownership to ensure code quality?

  • How to write a network game? [closed]

    - by Tom Wijsman
    Based on Why is so hard to develop a MMO?: Networked game development is not trivial; there are large obstacles to overcome in not only latency, but cheat prevention, state management and load balancing. If you're not experienced with writing a networked game, this is going to be a difficult learning exercise. I know the theory about sockets, servers, clients, protocols, connections and such things. Now I wonder how one can learn to write a network game: How to balance load problems? How to manage the game state? How to keep things synchronized? How to protect the communication and client from reverse engineering? How to work around latency problems? Which things should be computed local and which things on the server? ... Are there any good books, tutorials, sites, interesting articles or other questions regarding this? I'm looking for broad answers, but specific ones are fine too to learn the difference.

  • The How-To Geek Guide to Audio Editing: Cutting, Trimming & Arranging

    - by YatriTrivedi
    Audacity novices often start with lofty project ideas, but sometimes they lack the basics. Knowing how to cut and trim tracks is basic audio editing and is a fundamental starting point for making more elaborate arrangements. For this exercise, I’ll be making a ringtone from a Castlevania: Symphony of the Night track. I have the original CD and used that so I started with better quality audio than an MP3. You can follow along with any file you like, just so you get a feel for cutting, trimming, and arranging sound clips for yourself. I know which parts I want to edit in the track, but a quick play-through will help me look for those areas visually.

  • Are there non-programming related activities akin to solving programming problems ?

    - by julien
    I'm talking about particular activities, for which you can draw parallels with the specific kind of reasonning needed when solving programming problems. Counter examples are activities that would help in almost any situation, like : take a shower or any other, somewhat passive activities, which are only helpful in triggering this sort of asynchronous problem solving our brain does exercise, because you brain simply works better when you're fit EDIT : It seems this question was quite misunderstood. I wasn't asking about what you can do when stuck on a problem but rather, what kind of activities you have in you spare time that you think help you, more or less directly, solving programing problems.
