• Need the co-ordinates of innerPolygon

  - by user960567

  Let say I have this diagram, Given that i have all the co-ordinates of outer polygon and the distance between inner and outer polygon is d is also given. How to calculate the inner polygon co-ordinates? Edit: I was able to solved the issue by getting the mid-points of all lines. From these mid-points I can move d distance, So I can get three points. No I have 3 points and 3 slopes. From this, I can get three new equations. Simultaneously, solving the equation get the 3 points.

  Ok... changing the question here... I'm getting an error when I try this: SELECT COUNT ( DISTINCT mid, regexp_replace(na_fname, '\\s*', '', 'g'), regexp_replace(na_lname, '\\s*', '', 'g')) FROM masterfile; Is it possible to use regexp in a distinct clause like this?

• Attempting to find a formula for tessellating rectangles onto a board, where middle square can't be

  - by timemirror

  I'm working on a spatial stacking problem... at the moment I'm trying to solve in 2D but will eventually have to make this work in 3D. I divide up space into n x n squares around a central block, therefore n is always odd... and I'm trying to find the number of locations that a rectangle of any dimension less than n x n (eg 1x1, 1x2, 2x2 etc) can be placed, where the middle square is not available. So far I've got this.. total number of rectangles = ((n^2 + n)^2 ) / 4 ..also the total number of squares = (n (n+1) (2n+1)) / 6 However I'm stuck in working out a formula to find how many of those locations are impossible as the middle square would be occupied. So for example: [] [] [] [] [x] [] [] [] [] 3 x 3 board... with 8 possible locations for storing stuff as mid square is in use. I can use 1x1 shapes, 1x2 shapes, 2x1, 3x1, etc... Formula gives me the number of rectangles as: (9+3)^2 / 4 = 144/4 = 36 stacking locations However as the middle square is unoccupiable these can not all be realized. By hand I can see that these are impossible options: 1x1 shapes = 1 impossible (mid square) 2x1 shapes = 4 impossible (anything which uses mid square) 3x1 = 2 impossible 2x2 = 4 impossible etc Total impossible combinations = 16 Therefore the solution I'm after is 36-16 = 20 possible rectangular stacking locations on a 3x3 board. I've coded this in C# to solve it through trial and error, but I'm really after a formula as I want to solve for massive values of n, and also to eventually make this 3D. Can anyone point me to any formulas for these kind of spatial / tessellation problem? Also any idea on how to take the total rectangle formula into 3D very welcome! Thanks!

• Mysql query problem

  - by Sergio

  I have a problem with (for me to complicated) MySql query. Okay, here is what I need to do: First I need to check messages that some specific user received $mid=$_SESSION['user']; $stat1=mysql_query("SELECT id, fromid, toid, subject FROM messages WHERE toid = '".$mid."' AND subject != 'not readed' GROUP BY fromid ") or die(mysql_error()); while ($h = mysql_fetch_array($stat1)) { $whosend=$h['fromid']; Second thing that I need to do is check the status of the users (deleted or not) who sent the messages ("fromid") to my specific user ("toid"). This I must do from another table: $stat2=mysql_query("SELECT id, status FROM members WHERE id='".$whosend."' AND status ='1'")or die(mysql_error()); while ($s = mysql_fetch_array($stat)) { Then my problems begin to show up. How can I get the number of the users who sent messages to my specific user with status =1? Not the number of the messages but the total number of the users who sent them. Is there any easier way to do this query? I tried with join tables like $stat=mysql_query("SELECT memebers.id, memebers.status, messages.toid, messages.fromid,messages.subject,messages.id FROM members, messages WHERE messages.toid='".$mid."' AND members.status ='7' .... But even in this query I need to have id's of the user who sent messages before this query so there will be another query before this join tables.

• php - usort or array_multisort?

  - by Simpson88Keys

  Trying to sort the array below by memnum in ascending order, and I'm a bit confused which is better to use... usort or array_multisort? I was thinking usort because it's multidimensional? Does anyone have an example of this? Array ( [0] => Array ( [memnum] => 3236467423 [mid] => 1104881300 [fname] => JOHN [lname] => DOE [add1] => OMITTED [add2] => [city] => CHESTERFIELD [state] => MI [zip] => 48051 [age] => 50 ) [1] => Array ( [memnum] => 3258467922 [mid] => 1105121457 [fname] => JANE [lname] => DOE [add1] => OMITTED [add2] => [city] => CHESTERFIELD [state] => MI [zip] => 48051 [age] => 50 ) [2] => Array ( [memnum] => 3237769108 [mid] => 1104489312 [fname] => BOB [lname] => DOE [add1] => OMITTED [add2] => [city] => CHESTERFIELD [state] => MI [zip] => 48051 [age] => 50 ) )

• Remove redundant SQL code

  - by Dave Jarvis

  Code The following code calculates the slope and intercept for a linear regression against a slathering of data. It then applies the equation y = mx + b against the same result set to calculate the value of the regression line for each row. Can the two separate sub-selects be joined so that the data and its slope/intercept are calculated without executing the data gathering part of the query twice?

• using ini file in vb6, problem with path to file

  - by DrPut

  I have read many articles about how to use an INI file within my VB6 project. I don't have a problem with the methods, my problem is how to make the EXE file find the INI file. I don't want to hard code the path in the program. I simply want the EXE to expect the INI file to be present in the same folder the EXE is executed from. When I run the program from inside VB6 IDE, the INI is found and processed. When I compile the program and run the EXE, nothing is found. My code looks like: gServer = sGetINI(sINIFile, "TOOLBOM", "ServerName", "?") where TOOLBOM is the [Section] and "ServerName" is the key for the value. I obtained the following code for the API: Rem API DECLARATIONS 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 Declare Function WritePrivateProfileString Lib "kernel32" Alias _ "WritePrivateProfileStringA" (ByVal lpApplicationName _ As String, ByVal lpKeyName As Any, ByVal lpString As Any, _ ByVal lpFileName As String) As Long Public Function sGetINI(sINIFile As String, sSection As String, sKey _ As String, sDefault As String) As String Dim sTemp As String * 256 Dim nLength As Integer sTemp = Space$(256) nLength = GetPrivateProfileString(sSection, sKey, sDefault, sTemp, _ 255, sINIFile) sGetINI = Left$(sTemp, nLength) End Function Public Sub writeINI(sINIFile As String, sSection As String, sKey _ As String, sValue As String) Dim n As Integer Dim sTemp As String sTemp = sValue Rem Replace any CR/LF characters with spaces For n = 1 To Len(sValue) If Mid$(sValue, n, 1) = vbCr Or Mid$(sValue, n, 1) = vbLf _ Then Mid$(sValue, n) = " " Next n n = WritePrivateProfileString(sSection, sKey, sTemp, sINIFile) End Sub

• How to find which delimiter was used during string split (VB.NET)

  - by typoknig

  Hi all, lets say I have a string that I want to split based on several characters, like ".", "!", and "?". How do I figure out which one of those characters split my string so I can add that same character back on to the end of the split segments in question? Dim linePunctuation as Integer = 0 Dim myString As String = "some text. with punctuation! in it?" For i = 1 To Len(myString) If Mid$(entireFile, i, 1) = "." Then linePunctuation += 1 Next For i = 1 To Len(myString) If Mid$(entireFile, i, 1) = "!" Then linePunctuation += 1 Next For i = 1 To Len(myString) If Mid$(entireFile, i, 1) = "?" Then linePunctuation += 1 Next Dim delimiters(3) As Char delimiters(0) = "." delimiters(1) = "!" delimiters(2) = "?" currentLineSplit = myString.Split(delimiters) Dim sentenceArray(linePunctuation) As String Dim count As Integer = 0 While linePunctuation > 0 sentenceArray(count) = currentLineSplit(count)'Here I want to add what ever delimiter was used to make the split back onto the string before it is stored in the array.' count += 1 linePunctuation -= 1 End While

• Unity - Mecanim & Rigidbody on Third Person Controller - Gravity bug?

  - by Celtc

  I'm working on a third person controller which uses physX to interact with the other objects (using the Rigidbody component) and Mecanim to animate the character. All the animations used are baked to Y, and the movement on this axis is controlled by the gravity applied by the rigidbody component. The configuration of the falling animation: And the character components configuration: Since the falling animation doesn't have root motion on XZ, I move the character on XZ by code. Like this: // On the Ground if (IsGrounded()) { GroundedMovementMgm(); // Stores the velocity velocityPreFalling = rigidbody.velocity; } // Mid-Air else { // Continue the pre falling velocity rigidbody.velocity = new Vector3(velocityPreFalling.x, rigidbody.velocity.y, velocityPreFalling.z); } The problem is that when the chracter starts falling and hit against a wall in mid air, it gets stuck to the wall. Here are some pics which explains the problems: Hope someone can help me. Thanks and sory for my bad english! PD.: I was asked for the IsGrounded() function, so I'm adding it: void OnCollisionEnter(Collision collision) { if (!grounded) TrackGrounded(collision); } void OnCollisionStay(Collision collision) { TrackGrounded(collision); } void OnCollisionExit() { grounded = false; } public bool IsGrounded() { return grounded; } private void TrackGrounded(Collision collision) { var maxHeight = capCollider.bounds.min.y + capCollider.radius * .9f; foreach (var contact in collision.contacts) { if (contact.point.y < maxHeight && Vector3.Angle(contact.normal, Vector3.up) < maxSlopeAngle) { grounded = true; break; } } } I'll also add a LINK to download the project if someone wants it.

• handling various frame layouts in android

  - by vaibhav

  i'm new to game development and am trying create a Contra or the old tmnt game (but a simple one) like game for android. for the game i decided to divide my main screen in three parts - upper for stats,mid for the game and lower for controls. my main.xml is <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <FrameLayout android:id="@+id/upper_bar" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1" > </FrameLayout> <FrameLayout android:id="@+id/fl" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="0.5" > </FrameLayout> <FrameLayout android:id="@+id/low_bar" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="0.85" > </FrameLayout> </LinearLayout> so i have created the gameview and gameloopthread classes for the mid surface(which is pretty standard). my problem is that how do i draw in the upper and lower frame layouts? should i make new classes for view and thread for each layout , should i do all this in the gameview class itself or is there any better way to implement this?

• 2D Side Scrolling game and "walk over ground" collision detection

  - by Fire-Dragon-DoL

  The question is not hard, I'm writing a game engine for 2D side scrolling games, however I'm thinking to my 2D side scrolling game and I always come up with the problem of "how should I do collision with the ground". I think I couldn't handle the collision with ground (ground for me is "where the player walk", so something heavily used) in a per-pixel way, and I can't even do it with simple shape comparison (because the ground can be tilted), so what's the correct way? I'know what tiles are and i've read about it, but how much should be big each tile to not appear like a stairs?Are there any other approach? I watched this game and is very nice how he walks on ground: http://www.youtube.com/watch?v=DmSAQwbbig8&feature=player_embedded If there are "platforms" in mid air, how should I handle them?I can walk over them but I can't pass "inside". Imagine a platform in mid air, it allows you to walk over it but limit you because you can't jump in the area she fits Sorry for my english, it's not my native language and this topic has a lot of keywords I don't know so I have to use workarounds Thanks for any answer Additional informations and suggestions: I'm doing a game course in this period and I asked them how to do this, they suggested me this approach (a QuadTree): -All map is divided into "big nodes" -Each bigger node has sub nodes, to find where the player is -You can find player's node with a ray on player position -When you find the node where the player is, you can do collision check through all pixels (which can be 100-200px nothing more) Here is an example, however i didn't show very well the bigger nodes because i'm not very good with photoshop :P How is this approach?

• I don't know C. And why should I learn it?

  - by Stephen

  My first programming language was PHP (gasp). After that I started working with JavaScript. I've recently done work in C#. I've never once looked at low or mid level languages like C. The general consensus in the programming-community-at-large is that "a programmer who hasn't learned something like C, frankly, just can't handle programming concepts like pointers, data types, passing values by reference, etc." I do not agree. I argue that: Because high level languages are easily accessible, more "non-programmers" dive in and make a mess, and In order to really get anything done in a high level language, one needs to understand the same similar concepts that most proponents of "learn-low-level-first" evangelize about. Some people need to know C. Those people have jobs that require them to write low to mid-level code. I'm sure C is awesome. I'm sure there are a few bad programmers who know C. My question is, why the bias? As a good, honest, hungry programmer, if I had to learn C (for some unforeseen reason), I would learn C. Considering the multitude of languages out there, shouldn't good programmers focus on learning what advances us? Shouldn't we learn what interests us? Should we not utilize our finite time moving forward? Why do some programmers disagree with this? I believe that striving for excellence in what you do is the fundamental deterministic trait between good programmers and bad ones. Does anyone have any real world examples of how something written in a high level language--say Java, Pascal, PHP, or Javascript--truely benefitted from a prior knowledge of C? Examples would be most appreciated. (revised to better coincide with the six guidelines.)

• Is SCCM overkill for medium-sized organizations?

  - by Le_Quack

  I am an IT technician in a high school with around 1600 students 250 staff and 800+ client computers mostly running Windows 7. Our team is composed of three members. My boss seems content with a network that works (just about) not necessarily a productive well maintained network that is easy to run and maintain. I'm still fairly early on in my I.T. career so I'm not up to speed on all the different endpoint management solutions that are available. I'm looking for a better way to manage clients (deploy software, track changes, inventory etc) I like the look of SCCM 2012's features but the case studies seem to be aimed at large multi-site infrastructural rather than a single mid sized site. Is SCCM suitable for a mid sized single site or is it aimed at much larger corporations? How can I determine whether or not an endpoint management solution like SCCM is a good fit for our organization? EDIT: Thanks for all the help I'll take a look at SCE and SCCM and get some proposals drawn up to take to my boss/deputy head

But when I run the command sudo aplay -l, I get the following output **** List of PLAYBACK Hardware Devices **** Failed to create secure directory (/home/ganessh/.config/pulse): Permission denied card 0: MID [HDA Intel MID], device 0: STAC92xx Analog [STAC92xx Analog] Subdevices: 0/1 Subdevice #0: subdevice #0 card 1: NVidia [HDA NVidia], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: NVidia [HDA NVidia], device 7: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: NVidia [HDA NVidia], device 8: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: NVidia [HDA NVidia], device 9: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 And the command lspci -v | grep -A7 -i "audio" outputs 00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 06) Subsystem: Dell Device 02a2 Flags: bus master, fast devsel, latency 0, IRQ 48 Memory at f0f20000 (64-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel 00:1c.0 PCI bridge: Intel Corporation 5 Series/3400 Series Chipset PCI Express Root Port 1 (rev 06) (prog-if 00 [Normal decode]) -- 02:00.1 Audio device: NVIDIA Corporation GF106 High Definition Audio Controller (rev a1) Subsystem: Dell Device 02a2 Flags: bus master, fast devsel, latency 0, IRQ 17 Memory at d3efc000 (32-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel 07:00.0 Network controller: Intel Corporation Ultimate N WiFi Link 5300 So, I assume that the drivers are properly installed but still I don't get any option in the settings or volume control. The same card used to work well back in 2010 versions(04 and 10) Any help is appreciated. Thanks

• MySQL/Apache: Replace spaces with underscores only in certain URLs

  - by javipas

  I'm having a problem with some images I'm using on my WordPress blog. After a migration I renamed every image replacing spaces with underscores, so HIDDEN_264_4062_FOTO_IDF los MID.jpg was renamed to HIDDEN_264_4062_FOTO_IDF_los_MID.jpg But althought the trick was necessary and worked for most of the posts, some of them try to find the old image, with spaces: This is not found http://www.example.com/files/HIDDEN_264_4062_FOTO_IDF%20los%20MID.jpg and this should be the right URL http://www.example.com/files/HIDDEN_264_4062_FOTO_IDF_los_MID.jpg Careful, though, 'cause the "%20" is only shown on the browser: the text on the database shows spaces, not "%20". I'd like to know if maybe I could make a SQL query in my WordPress MySQL database that replaces spaces in .jpg files with underscores. The path of the images is always the same, so the rule should transform this: /files/HIDDEN_264_4062_FOTO_IDF los MID.jpg /files/HIDDEN_264_4062_FOTO_IDF_los_MID.jpg the "/files/HIDDEN_264_" part is always the same, but the rest varies. Is some way to perform this? Maybe a rewrite rule on Apache (our current webserver)?

• Issue with domain redirection

  - by phphunger

  I have a flash games website which is hosted at godaddy server. But because of heavy traffic on my site the godaddy server gets down. So I changed the hosting to Midphase server. The strange thing is i have created new name servers and new database in my mid phase server but still the web site is coming from the godaddy server. When i do any modifications from the godaddy ftp i am getting the modifications but when i do any modifications in the mid phase server. No changes are happening. One strange thing is the who.is is showing the new name servers and new server details but not getting the new servers contents. Can anyone help me in this regard?

• SCCM? Overkill?

  - by Le_Quack

  T. technician in a high school with around 1600 students 250 staff and 800+ client computers mostly running W7 I'm looking for a better way to manage clients (deploy software, track changes, inventory etc) I like the look of SCCM 2012 features but the case studies seem to be aimed at large multi-site infrastructural rather than a single mid sized site. Is SCCM suitable for a mid sized single site or is it aimed at much larger corporations, if so what would be more suitable Just a note about me and my situation. I work as a technician in a school part of a team of 3. My boss seems content with a network that works (just about) not a productive well maintained network that is easy to run and maintain. I'm still fairly early on in my I.T. career so sorry if I'm not up to speed on all products. EDIT: Thanks for all the help I'll take a look at SCE and SCCM and get some proposals drawn up to take to my boss/deputy head

• Bug in CF9: values for unique struct keys referenced and overwritten by other keys.

  - by Gin Doe

  We've run into a serious issue with CF9 wherein values for certain struct keys can be referenced by other keys, despite those other keys never being set. See the following examples: Edit: Looks like it isn't just something our servers ate. This is Adobe bug-track ticket 81884: http://cfbugs.adobe.com/cfbugreport/flexbugui/cfbugtracker/main.html#bugId=81884. <cfset a = { AO = "foo" } /> <cfset b = { AO = "foo", B0 = "bar" } /> <cfoutput> The following should throw an error. Instead both keys refer to the same value. <br />Struct a: <cfdump var="#a#" /> <br />a.AO: #a.AO# <br />a.B0: #a.B0# <hr /> The following should show a struct with 2 distinct keys and values. Instead it contains a single key, "AO", with a value of "bar". <br />Struct b: <cfdump var="#b#" /> This is obviously a complete show-stopper for us. I'd be curious to know if anyone has encountered this or can reproduce this in their environment. For us, it happens 100% of the time on Apache/CF9 running on Linux, both RH4 and RH5. We're using the default JRun install on Java 1.6.0_14. To see the extent of the problem, we ran a quick loop to find other naming sequences that are affected and found hundreds of matches for 2 letter key names. A similar loop found more conflicts in 3 letter names. <cfoutput>Testing a range of affected key combinations. This found hundreds of cases on our platform. Aborting after 50 here.</cfoutput> <cfscript> teststring = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"; stringlen = len(teststring); matchesfound = 0; matches = ""; for (i1 = 1; i1 <= stringlen; i1++) { symbol1 = mid(teststring, i1, 1); for (i2 = 1; i2 <= stringlen; i2++) { teststruct = structnew(); symbol2 = mid(teststring, i2, 1); symbolwhole = symbol1 & symbol2; teststruct[ symbolwhole ] = "a string"; for (q1 = 1; q1 <= stringlen; q1++) { innersymbol1 = mid(teststring, q1, 1); for (q2 = 1; q2 <= stringlen; q2++) { innersymbol2 = mid(teststring, q2, 1); innersymbolwhole = innersymbol1 & innersymbol2; if ((i1 != q1 || i2 != q2) && structkeyexists(teststruct, innersymbolwhole)) { // another affected pair of keys! writeoutput ("<br />#symbolwhole# = #innersymbolwhole#"); if (matchesfound++ > 50) { // we've seen enough abort; } } } } } } </cfscript> And edit again: This doesn't just affect struct keys but names in the variables scope as well. At least the variables scope has the presence of mind to throw an error, "can't load a null": <cfset test_b0 = "foo" /> <cfset test_ao = "bar" /> <cfoutput> test_b0: #test_b0# <br />test_ao: #test_ao# </cfoutput>
