  • Entry level engineer question regarding memory management

    - by Ealianis
    It has been a few months since I started my position as an entry level software developer. Now that I am past some learning curves (e.g. the language, jargon, syntax of VB and C#) I'm starting to focus on more esoteric topics, as to write better software. A simple question I presented to a fellow coworker was responded with "I'm focusing on the wrong things." While I respect this coworker I do disagree that this is a "wrong thing" to focus upon. Here was the code (in VB) and followed by the question. Note: The Function GenerateAlert() returns an integer. Dim alertID as Integer = GenerateAlert() _errorDictionary.Add(argErrorID, NewErrorInfo(Now(), alertID)) vs... _errorDictionary.Add(argErrorID, New ErrorInfo(Now(), GenerateAlert())) I originally wrote the latter and rewrote it with the "Dim alertID" so that someone else might find it easier to read. But here was my concern and question: Should one write this with the Dim AlertID, it would in fact take up more memory; finite but more, and should this method be called many times could it lead to an issue? How will .NET handle this object AlertID. Outside of .NET should one manually dispose of the object after use (near the end of the sub). I want to ensure I become a knowledgeable programmer that does not just rely upon garbage collection. Am I over thinking this? Am I focusing on the wrong things?

  • How to structure reading of commands given at a(n interactive) CLI prompt?

    - by Anto
    Let's say I have a program called theprogram (the marketing team was on strike when the product was to be named). I start that program by typing, perhaps not surprisingly, the program name as a command into a command prompt. After that, I get into a loop (from the users standpoint, an interactive command-line prompt), where one command will be read from the user, and depending on what command was given, the program will execute some instructions. I have been doing something like the following (in C-like pseudocode): main_loop{ in=read_input(); if(in=="command 1") do_something(); else if(in=="command 2") do_something_else(); ... } (In a real program, I would probably encapsulate more things into different procedures, this is just an example.) This works well for a small amount of commands, but let's say you have 100, 1000 or even 10 000 of them (the manual would be huge!). It is clearly a bad idea to have 10 000 ifs and else ifs after each other, for instance, the program would be hard to read, hard to maintain, contain a lot of boilerplate code... Yeah, you don't want to do that, so what approach would you recommend me to use (I will probably never use 10 000 commands in a program, but the solution should, at least preferably, be able to scale to that kind of massive (?) problems. The solution doesn't have to allow for arguments to the commands)?

  • Tips for Making this Code Testable [migrated]

    - by Jesse Bunch
    So I'm writing an abstraction layer that wraps a telephony RESTful service for sending text messages and making phone calls. I should build this in such a way that the low-level provider, in this case Twilio, can be easily swapped without having to re-code the higher level interactions. I'm using a package that is pre-built for Twilio and so I'm thinking that I need to create a wrapper interface to standardize the interaction between the Twilio service package and my application. Let us pretend that I cannot modify this pre-built package. Here is what I have so far (in PHP): <?php namespace Telephony; class Provider_Twilio implements Provider_Interface { public function send_sms(Provider_Request_SMS $request) { if (!$request->is_valid()) throw new Provider_Exception_InvalidRequest(); $sms = \Twilio\Twilio::request('SmsMessage'); $response = $sms->create(array( 'To' => $request->to, 'From' => $request->from, 'Body' => $request->body )); if ($this->_did_request_fail($response)) { throw new Provider_Exception_RequestFailed($response->message); } $response = new Provider_Response_SMS(TRUE); return $response; } private function _did_request_fail($api_response) { return isset($api_response->status); } } So the idea is that I can write another file like this for any other telephony service provided that it implements Provider_Interface making them swappable. Here are my questions: First off, do you think this is a good design? How could it be improved? Second, I'm having a hard time testing this because I need to mock out the Twilio package so that I'm not actually depending on Twilio's API for my tests to pass or fail. Do you see any strategy for mocking this out? Thanks in advance for any advice!

  • Licensing a website's code [on hold]

    - by RosiePea
    I just changed to a new contract that I want to use with all my future clients. I love this contract. It's in plain English, very readable, very understandable. It has this statement regarding ownership of the website after it's been paid for: After any outstanding balance for the project is paid, we will assign to you all copyrights in the graphical and visual elements of the design that we will create under the scope of this project. However, we will retain the copyright to all coding elements, but will provide you with a license for you to use these elements in the deliverables of this project. What is this license of which it speaks? I understand the concept: I maintain all rights to my code but allow them to use it in this particular website. That part's new in this contract, and I like it a lot. But now... what? I have to come up with a license to hand the client when the website is paid for. But which license? And do I physically (or electronically) give them something, a document kind of like the contract itself? I've been reading all about licenses all day today and I'm no closer to answering this question. Any words of advice out there?

  • Dealing with bilingual(spoken language) code?

    - by user1525
    So I've got to work with this set of code here for a re-write, and it's written by people who speak both English and French. Here's a snapshot of what I'm talking about (only, about 4000 lines of this) function refreshDest(FormEnCours,dest,hotel,duration) { var GateEnCours; GateEnCours = FormEnCours.gateway_dep.options[FormEnCours.gateway_dep.selectedIndex].value; if (GateEnCours == "") { FormEnCours.dest_dep.length = 0 } else if (FormEnCours.dest_dep != null && FormEnCours.dest_dep.type && FormEnCours.dest_dep.value != "ALL") { if (Destinations[GateEnCours] == null || Destinations[GateEnCours].length == 0) { RetreiveDestinations(FormEnCours,GateEnCours,dest,hotel,duration); } else { refreshDestSuite(FormEnCours,GateEnCours,dest,hotel,duration); } } } function refreshDuration(FormEnCours,GateEnCours,DestEnCours,hotel,duration) { // Refresh durations var FlagMoinsDe5Jours = ""; var Flag5a10jours = ""; var Flag11a16jours = ""; var FlagPlusDe16Jours = ""; ....... Is there any approach that I, as a speaker of only one of these languages, can use to make this entire process a lot less painful for both figuring out what everything does, and then refactoring it?

  • Parallelize code using CUDA [migrated]

    - by user878944
    If I have a code which takes struct variable as input and manipulate it's elements, how can I parallelize this using CUDA? void BackpropagateLayer(NET* Net, LAYER* Upper, LAYER* Lower) { INT i,j; REAL Out, Err; for (i=1; i<=Lower->Units; i++) { Out = Lower->Output[i]; Err = 0; for (j=1; j<=Upper->Units; j++) { Err += Upper->Weight[j][i] * Upper->Error[j]; } Lower->Error[i] = Net->Gain * Out * (1-Out) * Err; } } Where NET and LAYER are structs defined as: typedef struct { /* A LAYER OF A NET: */ INT Units; /* - number of units in this layer */ REAL* Output; /* - output of ith unit */ REAL* Error; /* - error term of ith unit */ REAL** Weight; /* - connection weights to ith unit */ REAL** WeightSave; /* - saved weights for stopped training */ REAL** dWeight; /* - last weight deltas for momentum */ } LAYER; typedef struct { /* A NET: */ LAYER** Layer; /* - layers of this net */ LAYER* InputLayer; /* - input layer */ LAYER* OutputLayer; /* - output layer */ REAL Alpha; /* - momentum factor */ REAL Eta; /* - learning rate */ REAL Gain; /* - gain of sigmoid function */ REAL Error; /* - total net error */ } NET; What I could think of is to first convert the 2d Weight into 1d. And then send it to kernel to take the product or just use the CUBLAS library. Any suggestions?

  • how to speed up this code? [migrated]

    - by dot
    I have some code that's taking over 3 seconds to complete. I'm just wondering if there's a faster way to do this. I have a string with anywhere from 10 to 70 rows of data. I break it up into an array and then loop through the array to find specific patterns. $this->_data = str_replace(chr(27)," ",$this->_data,$count);//strip out esc character $this->_data = explode("\r\n", $this->_data); $detailsArray = array(); foreach ($this->_data as $details) { $pattern = '/(\s+)([0-9a-z]*)(\s+)(100\/1000T|10|1000SX|\s+)(\s*)(\|)(\s+)(\w+)(\s+)(\w+)(\s+)(\w+)(\s+)(1000FDx|10HDx|100HDx|10FDx|100FDx|\s+)(\s*)(\w+)(\s*)(\w+|\s+)(\s*)(0)/i'; if (preg_match($pattern, $details, $matches)) { array_push($detailsArray, array( 'Port' => $matches[2], 'Type' => $matches[4], 'Alert' => $matches[8], 'Enabled' => $matches[10], 'Status' => $matches[12], 'Mode' => $matches[14], 'MDIMode' => $matches[16], 'FlowCtrl' => $matches[18], 'BcastLimit' => $matches[20])); }//end if }//end for $this->_data = $detailsArray; Just wondering if you think there's a way to make it more efficient. Thanks.

  • A Quick HLSL Question (How to modify some HLSL code)

    - by electroflame
    Thanks for wanting to help! I'm trying to create a circular, repeating ring (that moves outward) on a texture. I've achieved this, to a degree, with the following code: float distance = length(inTex - in_ShipCenter); float time = in_Time; ///* Simple distance/time combination */ float2 colorIndex = float2(distance - time, .3); float4 shipColor = tex2D(BaseTexture, inTex); float4 ringColor = tex2D(ringTexture, colorIndex); float4 finalColor; finalColor.rgb = (shipColor.rgb) + (ringColor.rgb); finalColor.a = shipColor.a; // Use the base texture's alpha (transparency). return finalColor; This works, and works how I want it to. The ring moves outward from the center of the texture at a steady rate, and is constrained to the edges of the base texture (i.e. it won't continue past an edge). However, there are a few issues with it that I would like some help on, though. They are: By combining the color additively (when I set finalColor.rgb), it makes the resulting ring color much lighter than I want (which, is pretty much the definition of additive blending, but I don't really want additive blending in this case). I would really like to be able to pass in the color that I want the ring to be. Currently, I have to pass in a texture that contains the color of the ring, but I think that doing it that way is kind of wasteful and overly-cumbersome. I know that I'm probably being an idiot over this, so I greatly appreciate the help. Some other (possibly relevant) information: I'm using XNA. I'm applying this by providing it to a SpriteBatch (as an Effect). The SpriteBatch is using BlendState.NonPremultiplied. Thanks in advance! EDIT: Thanks for the answers thus far, as they've helped me get a better grasp of the color issue. However, I'm still unsure of how to pass a color in and not use a texture. i.e. Can I create a tex2D by using a float4 instead of a texture? Or can I make a texture from a float4 and pass the texture in to the tex2D? DOUBLE EDIT: Here's some example pictures: With the effect off: With the effect on: With the effect on, but with the color weighting set to full: As you can see, the color weighting makes the base texture completely black (The background is black, so it looks transparent). You can also see the red it's supposed to be, and then the white-ish it really is when blended additively.

  • Binary on the Coat of Arms of the Governor General of Canada

    - by user132636
    Can you help me further this investigation? Here is about 10% of the work I have done on it. I present it only to see if there are any truly curious people among you. I made a video a few weeks ago showing some strange things about the Governor General's Coat of Arms and the binary on it. Today, I noticed something kinda cool and thought I would share. Here is the binary as it appears on the COA: 110010111001001010100100111010011 As DEC: 6830770643 (this is easily found on the web) Take a close look at that number. What do you notice about it? It has a few interesting features, but here is the one no one has pointed out... Split it down the middle and you have 68307 70643. The first digit is double the value of the last digit. The second digit is double the second last digit. The third digit is half of the third to last digit. And the middle ones are even or neutral. At first, I thought of it as energy. ++-nnnn+-- But actually you can create something else with it using the values. 221000211. See how that works. You may be asking why that is significant. Bare with me. I know 99% are rolling their eyes. 221000211 as base3 gives you this as binary: 100011101000111 100011101000111 as HEX is 4747, which converts to "GG". Initials of Governor General. GG.ca is his website. When you convert to base 33 (there are 33 digits in the original code) you get "GOV" Interesting? :D There is a lot more to it. I'll continue to show some strange coincidences if anyone is interested. Sorry if I am not explaining this correctly. By now you have probably figured out that I have no background in this. Which is why I am here. Thank you.

  • How (recipe) to build only one kernel module?

    - by Pro Backup
    I have a bug in a Linux kernel module that causes the stock Ubuntu 14.04 kernel to oops (crash). That is why I want to edit/patch the source of only that single kernel module to add some extra debug output. The kernel module in question is mvsas and not necessary to boot. For that reason I don't see any need to update any initrd images. I have read a lot of information (as shown below) and find the setup and build process confusion. I need two recipes: to setup/configure the build environment once steps to do after editing any source file of this kernel module (.c and .h) and converting that edit into a new kernel module (.ko) The sources that have been used are: build one kernel module - Google search http://www.linuxquestions.org/questions/linux-kernel-70/rebuilding-a-single-kernel-module-595116/ http://stackoverflow.com/questions/8744087/how-to-recompile-just-a-single-kernel-module http://www.pixelbeat.org/docs/rebuild_kernel_module.html How do I build a single in-tree kernel module? http://ubuntuforums.org/showthread.php?t=1153067 http://ubuntuforums.org/showthread.php?t=2112166 http://ubuntuforums.org/showthread.php?t=1115593 build one kernel module ubuntu - Google search 'make +single +kernel +module' - Ask Ubuntu 'make +kernel +module' - Ask Ubuntu My makefile results in: No rule to make target `arch/x86/tools/relocs.c', needed '"Invalid module format"' - Ask Ubuntu Driver installation: compiling source code for newer kernel Modprobe: 'Invalid nodule format', yet works after insmod "Symbol version dump" "is missing" - Google search http://stackoverflow.com/questions/9425523/should-i-care-that-the-symbol-version-dump-is-missing-how-do-i-get-one Where can I find the corresponding Module.symvers and .config files for 12.04.3 i386 server?

  • Upgrading Code from 2007 to 2010

    - by MOSSLover
    So I’ve been doing some upgrades just to see if things will work from 2007 to 2010.  So far most of the stuff I want works, but obviously there are some things that break.  Did you guys know that in 2007 you could add a webpart to the view pages for lists and libraries without losing the toolbar?  In 2010 the ribbon disappears every time you add a webpart.  So if you are using Scot Hillier’s Codeplex project to hide buttons it will not work the same way, because the ribbon is going to disappear altogether. I have also learned another reason why standalone installations are the bane of my existence.  Nine times out of ten the installation is done using Network Service as the application pool account.  You are wondering why is this bad?  Well, let’s just say the site collection administrator with local admin rights wants to attach the IIS Worker process and debug say a webpart.  Visual Studio 2010 will throw a nasty error that tells you that you are not an administrator.  You will say, but I am an administrator?  I have all the correct group permissions on the server and on SQL and in SharePoint.  Then you will go in and decide let’s add my own admin account just to see if I can attach the debugger and you will notice that works properly.  So the morale of the story is create a separate account on your development environment to run all the SharePoint Services and such.  You don’t need to go all out and create the best practices amount of accounts if it’s just your dev environment.  I would at least create one single account to run all your SharePoint process (Services, SQL, and App Pool).  Also, don’t run a standalone install unless you want to kill kittens (this is a quote from Todd Klindt).  We love kittens they are cute and awesome.  Besides you learn more if you click Complete and just skip standalone.  You will learn how to setup SQL Server 2008 and you will learn how to configure your environment.  It will help you in the long run.  So I have ranted enough for today I figure these are enough tidbits for you this time around.  The two of you who read my blog and I know some of you are friends who don’t understand SharePoint.  I might as well have just done “wahwahwahwah” in Charlie Brown adult speak.  Thanks for reading as usual.  I’ll catch you all when I complain more about the upgrade process and share more tidbits, which will inevitably become a presentation at a conference or two.

  • Any reliable polygon normal calculation code?

  • Drawing 2D Grid in 3D View - Need help with method

    - by Deukalion
    I'm trying to draw a simple 2D grid for an editor, to able to navigate more clearly around the 3D space, but I can't render it: Grid2D class, creates a grid of a certain size at a location and should just draw lines. public class Grid2D : IShape { private VertexPositionColor[] _vertices; private Vector2 _size; private Vector3 _location; private int _faces; public Grid2D(Vector2 size, Vector3 location, Color color) { float x = 0, y = 0; if (size.X < 1f) { size.X = 1f; } if (size.Y < 1f) { size.Y = 1f; } _size = size; _location = location; List<VertexPositionColor> vertices = new List<VertexPositionColor>(); _faces = 0; for (y = -size.Y; y <= size.Y; y++) { vertices.Add(new VertexPositionColor(location + new Vector3(-size.X, y, 0), color)); vertices.Add(new VertexPositionColor(location + new Vector3(size.X, y, 0), color)); _faces++; } for (x = -size.X; x <= size.X; x++) { vertices.Add(new VertexPositionColor(location + new Vector3(x, -size.Y, 0), color)); vertices.Add(new VertexPositionColor(location + new Vector3(x, size.Y, 0), color)); _faces++; } _vertices = vertices.ToArray(); } public void Render(GraphicsDevice device) { device.DrawUserPrimitives<VertexPositionColor>(PrimitiveType.LineList, _vertices, 0, _faces); } } Like this: +----+----+----+----+ | | | | | +----+----+----+----+ | | | | | +----+----+----+----+ | | | | | +----+----+----+----+ | | | | | +----+----+----+----+ Anyone knows what I'm doing wrong? If I add a Shape without texture, it's set automatically to VertexColorEnabled and TextureEnabled = false. This is how I render it: foreach (RenderObject render in _renderObjects) { render.Effect.Projection = projection; render.Effect.View = view; render.Effect.World = world; foreach (EffectPass pass in render.Effect.CurrentTechnique.Passes) { pass.Apply(); try { // Could be a Grid2D render.Shape.Render(_device); } catch { throw; } } } Exception is thrown: The current vertex shader declaration does not include all the elements required by the current Vertex Shader. Normal0 is missing. Simply put, I can't figure out how to draw a few lines. I want to draw them one at a time and I guess that's the problem I haven't figured out, and even when I tried rendering vertices[i], vertices[i+1] and primitiveCount = 1, vertices = 2, and so on it didn't work either. Any suggestions?

  • Code Design question, circular reference across classes?

    - by dsollen
    I have no code here, as this is more of a design question (I assume this is still the best place to ask it). I have a very simple server in java which stores a mapping between certain values and UUID which are to be used by many systems across multiple platforms. It accepts a connection from a client and creates a clientSocket which stores the socket and all the other relevant data unique to that connection. Each clientSocket will run in their own thread and will block on the socket waiting for a read. I expect very little strain on this system, it will rarely get called, but when it does get a call it will need to respond quickly and due to the risk of it having a peak time with multiple calls coming in at once threaded is still better. Each thread has a reference to a Mapper class which stores the mapping of UUID which it's reporting to others (with proper synchronization of course). This all works until I have to add a new UUID to the list. When this happens I want to report to all clients that care about that particular UUID that a new one was added. I can't multicast (limitation of the system I'm running on) so I'm having each socket send the message to the client through the established socket. However, since each thread only knows about the socket it's waiting on I didn't have a clear method of looking up every thread/socket that cares about the data to inform them of the new UUID. Polling is out mostly because it seems a little too convoluted to try to maintain a list of newly added UUID. My solution as of now is to have the 'parent' class which creates the mapper class and spawns all the threads pass itself as an argument to the mapper. Then when the mapper creates a new UUID it can make a call to the parent class telling it to send out updates to all the other sockets that care about the change. I'm concerned that this may be a bad design due to the use of a circular reference; parent has a reference to mapper (to pass it to new ClientSocket threads) and mapper points to parent. It doesn't really feel like a bad design to me but I wanted to check since circular references are suppose to be bad. Note: I realize this means that the thread associated with whatever socket originally received the request that spawned the creation of a UUID is going to pay the 'cost' of outputting to all the other clients that care about the new UUID. I don't care about this; as I said I suspect the client to receive only intermittent messages. It's unlikely for one socket to receive multiple messages at one time, and there won't be that many sockets so it shouldn't take too long to send messages to each of them. Perhaps later I'll fix the fact that I'm saddling higher work load on whatever unfortunate thread gets the first request; but for now I think it's fine.

  • Custom HTTP Status Codes (a la Twitter 420: Enhance Your Calm) [migrated]

    - by Max Bucknell
    I'm currently implementing an HTTP API, my first ever. I've been spending a lot of time looking at the Wikipedia page for HTTP status codes, because I'm determined to implement the right codes for the right situations. Listed on that page is a code with number 420, which is a custom code that Twitter used to use for rate limiting. There is already a code for rate limiting, though. It's 429. This led me to wonder why they would set a custom one, when there is already a use case. Is that just being cute? And if so, then which circumstances would make it acceptable to return a different status code, and what, if any problems may clients have with it? I read somewhere that Mozilla doesn't implement the joke 418: I’m a teapot response, which makes me think that clients choose which status codes they implement. If that's true, then I can imagine Twitter's funny little enhance your calm code being problematic. Unless I'm mistaken, and we can appropriate any code number to mean whatever we like, and that only convention dictates that 404 means not found, and 429 means take it easy.

What I want is for the columns to adjust to the size of the largest string within each column, where the total of all width of columns does not exceed the width of the webgrid. At the same time however if the width of all columns is less than the width of the webgrid I want each column to adjust proportionately so that the total of columns widths equal the width of the webgrid. Can anyone help me with this logic?

  • Android: ImageView scales up source image

    - by legr3c
    I can't seem to get my ImageView to display its source image in its original size. The ImageView looks like this: <ImageView android:id="@+id/Logo" android:src="@drawable/logo" android:layout_width="wrap_content" android:layout_height="wrap_content" > </ImageView> The source image is 140 pixels wide, yet on the Nexus One's screen, which is 480 pixels wide it uses up half of the width. Using absolute values in px or dp for the width and height changes nothing. The image also looks very antialiased from the upscaling. Why is this happening and how can I prevent it?

  • Multiplying char and int together in C

    - by teehoo
    Today I found the following: #include <stdio.h> int main(){ char x = 255; int z = ((int)x)*2; printf("%d\n", z); //prints -2 return 0; } So basically I'm getting an overflow because the size limit is determined by the operands on the right side of the = sign?? Why doesn't casting it to int before multiplying work? In this case I'm using a char and int, but if I use "long" and "long long int" (c99), then I get similar behaviour. Is it generally advised against doing arithmetic with operands of different sizes?

  • UIWebView - get total height of contents using Javascript

    - by Emil
    Hey. I'm trying to use a UIWebView for displaying content higher than the screen of the iPhone, without needing to scroll in the webView itself. For that, I need a way to get the total document size, including the scrollable area. I have tried a number of different Javascript solutions: (document.height !== undefined) ? document.height : document.body.offsetHeight // Returns height of UIWebView document.body.offsetHeight // Returns zero document.body.clientHeight // Returns zero document.documentElement.clientHeight // Returns height of UIWebView window.innerHeight // Returns height of UIWebView -2 Can you think of any other way to do it? Thanks.

  • Android multiple screen sizes and density problems

    - by Ben Mc
    I'm having a real problem with my drawables that I just can't seem to figure out. The problem is this: There are screen sizes at approximately 320x480, 480x800, 480x854 Then there are most commonly densities at 1.0 (160) and 1.5 (240) Now, on a Droid, the screen size is 480x800 and the density is reporting using DisplayMetrics as 1.5 On the G1, it's 320x480 and reporting back at a density of 1.0 BUT tablet devices are reporting back at 480x800 with a density of 1.0 (160) So, I'm going mad because I can put 320x480 images in the drawables-mdpi folder and 480x800 images in the drawables-hdpi folder, but on Tablet computers, no matter what it's not resizing up anything to a full screen. Any help would be greatly appreciated. I just want all of my 320x480 images to scale up regardless of the device.

  • What are Android different screens dimensions in dp for different screens (e.g. xlarge = 960dp x 720dp)?

    - by Zizo
    in this link: Range of screens supported, Android team mentioned that: As you design your UI for different screen sizes, you'll discover that each design requires a minimum amount of space. So, each generalized screen size above has an associated minimum resolution that's defined by the system. These minimum sizes are in "dp" units—the same units you should use when defining your layouts—which allows the system to avoid worrying about changes in screen density. xlarge screens are at least 960dp x 720dp large screens are at least 640dp x 480dp normal screens are at least 470dp x 320dp small screens are at least 426dp x 320dp So, If I want to support all Android screens, can I create images, for full screen view, in those dimensions and that will be sufficient condition to support all available screens? or they are just the minimum sizes, and I need other dimensions? If other dimensions are needed, Please list them as in the list above. Thanks in Advance.
