Overcoming Inertia - How to Just Get Going on Stuff

- by kronoz

I wondered whether you guys could help me - I have a big problem with overcoming inertia, i.e. how to just get started on a project/work when you simply feel the inertia of not being in the right 'zone' to do work such that it really becomes pretty damn tough to actually get on with what you want to do. Forgive me quoting my blog post where I try to express the problem as best I can:- The problem is that it feels so damned difficult to exert the force required to shift from one mode to another, so much so that you find it almost inconceivable to do so at the time. You need to force yourself somehow, or at least find some sort of hack to trick yourself into it. Do you guys have any ideas/hacks as to how to overcome this? Thanks in advance, and hopefully the community feel this question is valid for stack overflow (I have set it community wiki due to its fairly subjective nature.)

Javascript for a prompt which accepts simple math as a value and then returns the answer

- by user1139403

I have written a snippet of code in javascript, for a prompt to appear when clicked. I want to be able to enter a simple math problem (i.e. 230/2) and have it output the answer, rather than the math problem I just entered. Your help will be much appreciated. <!DOCTYPE html> <html> <body> <button onclick="myFunction()">Click me</button> <p id="demo"></p> <script type="text/javascript"> function myFunction() { var x; var mathProblem=prompt("Enter your math problem",""); if (name!=null) { x = mathProblem; document.getElementById("demo").innerHTML = x; } } </script> </body> </html>

Error 3032 during EF 4.0 validation

- by Mohammadreza

Hi guys. I have a table that has a column called "rowguid" with default value of newguid(). After I delete the generated property in the Entity Framework 4.0 designer, whenever I try to build or validate the model I receive the following error message. Error 3023: Problem in mapping fragments starting at line 1460:Column People.rowguid in table People must be mapped: It has no default value and is not nullable. It's an obvious error message but the problem is that the column HAS default value. Does anyone knows what the problem is? Thanks.

how could I pass closure problems in order to increment a global var

- by hyptos

I have a simple goal, I would like to increment a variable but I'm facing the closure problem. I've read why this s happening here How do JavaScript closures work? But I can't find the solution to my problem :/ let's assume this part of code I took from the link. function say667() { // Local variable that ends up within closure var num = 666; var sayAlert = function() { alert(num); //incrementation } num++; return sayAlert; } I would like to increment num within the function and to keep the changes to num. How could I do that ? Here is the JsFiddle where I have my problem, I can't figure out how to increment my totalSize and keep it. http://jsfiddle.net/knLbv/2/ I don't want a local variable that ends up with closure.

Comobox event SelectedValueChanged

- by IordanTanev

Hi, i have simple question may be someone asked it before me but i could not find it.Let say i have datatable that has some data from the database and i want to bind it to a combobox i use standart code like this comboBox1.BeginUpdate( ); comboBox1.ValueMember = "id"; comboBox1.DisplayMember = "name"; comboBox1.DataSource = dt; comboBox1.EndUpdate( ); The problem is during this binding the event SelectedValueChanged is fired.The problem is that rebind combo several times when outher values change and every time i must do sometihn like this comboBox1.SelectedIndexChanged -= new System.EventHandler( this.comboBox1_SelectedValueChanged ); my question is there a smarter way to skip the event when i comes from databinding not from user input.The problem is that i want to do it some how globaly in my control that inherits combobox and not to do it everytime in every from Best Regards, Iordand

How to remove the file which has opened handles?

- by SKINDER

PROBLEM HISTORY: Now I use Windows Media Player SDK 9 to play AVI files in my desktop application. It works well on Windows XP but when I try to run it on Windows 7 I caught an error - I can not remove AVI file immediately after playback. The problem is that there are opened file handles exist. On Windows XP I have 2 opened file handles during the playing file and they are closed after closing of playback window but on Windows 7 I have already 4 opened handles during the playing file and 2 of them remain after the closing of playback window. They are become free only after closing the application. QUESTION: How can I solve this problem? How to remove the file which has opened handles? May be exists something like "force deletion"? Thanks.

Decimal point removed from decimals in a Serialized XML

- by MiguelM

I'm using XmlSerializer with classes created from a xsd using xsd.exe. It has worked fine for months. Now I'm receiving reports that in some cases the created xml file has all decimals serialized without a decimal point, e.g. 123.45 is serialized as 12345. I haven't been able to reproduce the problem, but I'm suspecting it may be related to localization. This is my first C# project, so I may be overlooking something basic. Could localization cause this problem? How can I make the serialization process locale independent? Any idea of something else that could cause this problem?

what are the recent dataStructure and algorithms that one should know?

- by Shamik

Recently I came across the SkipList data structure. It really helped me to solve one otherwise critical problem to be solved. I was struggling to solve the same problem with Balanced Binary tree but it became very complex as the tree needs to be always balanced and I wanted to know the existence of not only a particular value but values in certain range. SkipList helped me to solve that problem effectively. I am wondering what else data structures that I need to know? I know - Array, List, Stack, Queue, Linked List, hashtable, tree and its different forms like B-tree, Trie etc. Would like to know if you find some other data structure/concept very interesting to know yet effective enough to be used in a daily development cycle.

Escaping quotes twice in PHP

- by Genadinik

Hello, I have a complicated form where I first have to take some _GET parameters and obviously I have to do a mysql_real_escape_string() on them since I look stuff up in the database with them. Them problem for me is after the initial db lookup. When the user submits a form, I send them along as a _POST request and obviously have to do this mysql_real_escape_string call again just in case someone tries to hack my site with a faked form submission. Then the problem I have is the arguments are escaped twice and my queries begin to look strange like this: select field1 , field2 , from my_table where some_id = \'.$lookup_id.\' ... So the system seems to be adding \' and it is messing me up :) Also, in my other forms I have not seen such behavior. Any ideas on what may be causing this? One weird thing is that I tried to send unescaped parameters to the post, and the same problem happens. That is a clue, but not a sufficient one for me. :( Thanks, Alex

Python: Pickling highly-recursive objects without using `setrecursionlimit`

- by cool-RR

I've been getting RuntimeError: maximum recursion depth exceeded when trying to pickle a highly-recursive tree object. Much like this asker here. He solved his problem by setting the recursion limit higher with sys.setrecursionlimit. But I don't want to do that: I think that's more of a workaround than a solution. Because I want to be able to pickle my trees even if they have 10,000 nodes in them. (It currently fails at around 200.) (Also, every platform's true recursion limit is different, and I would really like to avoid opening this can of worms.) Is there any way to solve this at the fundamental level? If only the pickle module would pickle using a loop instead of recursion, I wouldn't have had this problem. Maybe someone has an idea how I can cause something like this to happen, without rewriting the pickle module? Any other idea how I can solve this problem will be appreciated.

Android / Java rare and seemingly impossible exception causing force close

- by Guzba

Hello all, I have an interesting problem being reported to me from an android application I have published. I have a two-dimensional array that I am iterating through using two for loops like so: for (int i = 0; i < arr.length; ++i) { for (int j = 0; j < arr[i].length; ++j) { if (arr[i][j] != 0) // does stuff } } The problem is, somehow arr[i][j] != 0 is throwing an ArrayIndexOutOfBoundsException. But very rarely. I have thousands of people use the app on a daily basis and get maybe twenty force close reports. Is this something I can't avoid, maybe a problem with the phones memory, etc. or is there something I can do that I haven't thought of yet? Thanks.

A submenu (`ToolStripMenuItem`) does not show automatically.

- by czuk

I have encountered strange problem with a three-level context menu. In some situation the sub menu does not show automatically. I have following structure of the menu: * AAA - level 1 * BBB - level 1 * CCC - level 2 * xxx - level 3 * yyy - level 3 * DDD - level 2 * zzz - level 3 * vvv - level 3 I start from a menu with two option AAA and BBB. After I move the cursor over BBB the second-level menu appears with two other options CCC and DDD. So far OK. Now, when I quickly move the cursor over DDD the third-level sub menu does not show up, but when I move the cursor back to CCC the sub menu shows up, and when I go back to DDD then the sub menu also shows. Why it does not show at first time? Have you ever encountered such a problem? I fixed the problem with MouseEnter and MouseLeave events, but I still wonder why it does not work properly without the events.

Is it possible to import specific class from project propreties

- by Alex

I have 2 projects. First project need to include second. When I copy sources from second project to first I need to modify manually import path to R.java file. The problem is that I need to use SVN external link connection between this 2 projects, that is mean, one project (the bigger one) will take sources from another through svn and should be able to use it without any modifications. If I would be able to specify R.java file path anywhere in project properties it will resolve my problem by changing manually that path. Need to specify that package name of these 2 projects are different. Another solution to resolve this problem also would be accepted. Thank you.

C# Express 2010 Multi-Threading

- by Chris Evans

Hi, I have a windows app that I have been running in c# Express 2008 for a year and have been trying to convert it over the last few days to 2010. The problem I am having is it is a multi-threaded application that has to run a series of code every second. What it does is have a main thread, that calls 3 worker threads, waits for them to finish then does some additional processing, sleeps till 1 second and runs again. The problem is part of the code can call a web service that takes 8 seconds to respond, so this bit of code gets called using ThreadPool.QueueUserWorkItem. The problem is when running in 2010 when this part of the code gets called the main thread continues to run but when it awakens the sub threads it hangs until the Threadpool method finishes running. This never happens in 2008. Any suggestions? So far I put that bit of code in it's own thread rather than using Threadpool but same issue.

SVN:Team member can checkout, commit; can't update

- by Casey K.

Hi all, got a weird problem for you: I've set up an svn server on a home machine, which is accessible to the members of my game team over DynDNS. So far so good- everyone was able to checkout the repo no problem. In addition, several team members and I were able to update and commit just fine. The conundrum is this: One of my team members, who is able to both checkout and commit, is unable to update. TortoiseSVN proffers: Error Could not open the requested SVN filesystem Has anyone dealt with this problem before? This isn't my first SVN rodeo, but I have to admit I'm stumped. Thanks!

question about missing element in array

- by davit-datuashvili

i have following problem from book introduction algorithm second edition by MIT university problem is following An array A[1 . . n] contains all the integers from 0 to n except one. It would be easy to determine the missing integer in O(n) time by using an auxiliary array B[0 . . n] to record which numbers appear in A. In this problem, however, we cannot access an entire integer in A with a single operation. The elements of A are represented in binary, and the only operation we can use to access them is “fetch the j th bit of A[i],” which takes constant time. Show that if we use only this operation, we can still determine the missing inte- ger in O(n) time please help

Rails - inheritance hierarchy of classes where an subtipe can play two roles

- by Miquel

I need to model Owners and Rentees in an application, so you have stuff that is always owned by someone and can be rented for someone else. I first approached this problem with Single Table Inheritance because both types of person will share all attributes, so you would have a model called Person associated to a table people with Owner and Rentee inheriting from Person. The problem is that Single type inheritance discerns subtypes using a field type and therefore a record in the table can represent either an Owner or a Rentee but not both at the same time, while in the real context you can have an Owner which is renting something from another Owner and therefore that person is at the same time an Owner and a Rentee. How would you approach this problem? Would you use separated tables fro owners and rentees? Is there any other type of table inheritance in Rails?
