  • Creating an API for an ASP.NET MVC site with rate-limiting and caching

    - by Maxim Z.
    Recently, I've been very interested in APIs, specifically in how to create them. For the purpose of this question, let's say that I have created an ASP.NET MVC site that has some data on it; I want to create an API for this site. I have multiple questions about this: What type of API should I create? I know that REST and oData APIs are very popular. What are the pros and cons of each, and how do I implement them? From what I understand so far, REST APIs with ASP.NET MVC would just be actions that return JSON instead of Views, and oData APIs are documented here. How do I handle writing? Reading from both API types is quite simple. However, writing is more complex. With the REST approach, I understand that I can use HTTP POST, but how do I implement authentication? Also, with oData, how does writing work in the first place? How do I implement basic rate-limiting and caching? From my past experience with APIs, these are very important things, so that the API server isn't overloaded. What's the best way to set these two things up? Can I get some sample code? Any code that relates to C# and ASP.NET MVC would be appreciated. Thanks in advance! While this is a broad question, I think it's not too broad... :) There are some similar questions to this one that are about APIs, but I haven't found any that directly address the questions I outlined here.

  • Obtaining XML from U.S. Postal Service (USPS) rate calculator API with PHP

    - by Chris F
    hoping somebody here can help me. I'm attempting to pull an XML page from the U.S. Postal Service (USPS) rate calculator, using PHP. Here is the code I am using (with my API login and password replaced of course): <? $api = "http://production.shippingapis.com/ShippingAPI.dll?API=RateV4&XML=<RateV4Request ". "USERID=\"MYUSERID\" PASSWORD=\"MYPASSWORD\"><Revision/><Package ID=\"1ST\">". "<Service>FIRST CLASS</Service><FirstClassMailType>PARCEL</FirstClassMailType>". "<ZipOrigination>12345</ZipOrigination><ZipDestination>54321</ZipDestination>". "<Pounds>0</Pounds><Ounces>9</Ounces><Container/><Size>REGULAR</Size></Package></RateV4Request>"; $xml_string = file_get_contents($api); $xml = simplexml_load_string($xml_string); ?> Pretty straightforward. However it never returns anything. I can paste the URL directly into my browser's address bar: http://production.shippingapis.com/ShippingAPI.dll?API=RateV4&XML=<RateV4RequestUSERID="MYUSERID" PASSWORD="MYPASSWORD"><Revision/><Package ID="1ST"><Service>FIRST CLASS</Service><FirstClassMailType>PARCEL</FirstClassMailType><ZipOrigination>12345</ZipOrigination><ZipDestination>54321</ZipDestination><Pounds>0</Pounds><Ounces>9</Ounces><Container/><Size>REGULAR</Size></Package></RateV4Request> And it returns the XML I need, so I know the URL is valid. But I cannot seem to capture it using PHP. Any help would be tremendously appreciated. Thanks in advance.

  • Problem measuring N times the execution time of a code block

    - by Nazgulled
    EDIT: I just found my problem after writing this long post explaining every little detail... If someone can give me a good answer on what I'm doing wrong and how can I get the execution time in seconds (using a float with 5 decimal places or so), I'll mark that as accepted. Hint: The problem was on how I interpreted the clock_getttime() man page. Hi, Let's say I have a function named myOperation that I need to measure the execution time of. To measure it, I'm using clock_gettime() as it was recommend here in one of the comments. My teacher recommends us to measure it N times so we can get an average, standard deviation and median for the final report. He also recommends us to execute myOperation M times instead of just one. If myOperation is a very fast operation, measuring it M times allow us to get a sense of the "real time" it takes; cause the clock being used might not have the required precision to measure such operation. So, execution myOperation only one time or M times really depends if the operation itself takes long enough for the clock precision we are using. I'm having trouble dealing with that M times execution. Increasing M decreases (a lot) the final average value. Which doesn't make sense to me. It's like this, on average you take 3 to 5 seconds to travel from point A to B. But then you go from A to B and back to A 5 times (which makes it 10 times, cause A to B is the same as B to A) and you measure that. Than you divide by 10, the average you get is supposed to be the same average you take traveling from point A to B, which is 3 to 5 seconds. This is what I want my code to do, but it's not working. If I keep increasing the number of times I go from A to B and back A, the average will be lower and lower each time, it makes no sense to me. Enough theory, here's my code: #include <stdio.h> #include <time.h> #define MEASUREMENTS 1 #define OPERATIONS 1 typedef struct timespec TimeClock; TimeClock diffTimeClock(TimeClock start, TimeClock end) { TimeClock aux; if((end.tv_nsec - start.tv_nsec) < 0) { aux.tv_sec = end.tv_sec - start.tv_sec - 1; aux.tv_nsec = 1E9 + end.tv_nsec - start.tv_nsec; } else { aux.tv_sec = end.tv_sec - start.tv_sec; aux.tv_nsec = end.tv_nsec - start.tv_nsec; } return aux; } int main(void) { TimeClock sTime, eTime, dTime; int i, j; for(i = 0; i < MEASUREMENTS; i++) { printf(" » MEASURE %02d\n", i+1); clock_gettime(CLOCK_REALTIME, &sTime); for(j = 0; j < OPERATIONS; j++) { myOperation(); } clock_gettime(CLOCK_REALTIME, &eTime); dTime = diffTimeClock(sTime, eTime); printf(" - NSEC (TOTAL): %ld\n", dTime.tv_nsec); printf(" - NSEC (OP): %ld\n\n", dTime.tv_nsec / OPERATIONS); } return 0; } Notes: The above diffTimeClock function is from this blog post. I replaced my real operation with myOperation() because it doesn't make any sense to post my real functions as I would have to post long blocks of code, you can easily code a myOperation() with whatever you like to compile the code if you wish. As you can see, OPERATIONS = 1 and the results are: » MEASURE 01 - NSEC (TOTAL): 27456580 - NSEC (OP): 27456580 For OPERATIONS = 100 the results are: » MEASURE 01 - NSEC (TOTAL): 218929736 - NSEC (OP): 2189297 For OPERATIONS = 1000 the results are: » MEASURE 01 - NSEC (TOTAL): 862834890 - NSEC (OP): 862834 For OPERATIONS = 10000 the results are: » MEASURE 01 - NSEC (TOTAL): 574133641 - NSEC (OP): 57413 Now, I'm not a math wiz, far from it actually, but this doesn't make any sense to me whatsoever. I've already talked about this with a friend that's on this project with me and he also can't understand the differences. I don't understand why the value is getting lower and lower when I increase OPERATIONS. The operation itself should take the same time (on average of course, not the exact same time), no matter how many times I execute it. You could tell me that that actually depends on the operation itself, the data being read and that some data could already be in the cache and bla bla, but I don't think that's the problem. In my case, myOperation is reading 5000 lines of text from an CSV file, separating the values by ; and inserting those values into a data structure. For each iteration, I'm destroying the data structure and initializing it again. Now that I think of it, I also that think that there's a problem measuring time with clock_gettime(), maybe I'm not using it right. I mean, look at the last example, where OPERATIONS = 10000. The total time it took was 574133641ns, which would be roughly 0,5s; that's impossible, it took a couple of minutes as I couldn't stand looking at the screen waiting and went to eat something.

  • AS3: Synchronize Timer event to actual time?

    - by Nebs
    I plan to use a timer event to fire every second (for a clock application). I may be wrong, but I assume that there will probably be a (very slight) sync issue with the actual system time. For example the timer event might fire when the actual system time milliseconds are at 500 instead of 0 (meaning the seconds will be partially 'out of phase' if you will). Is there a way to either synchronize the timer event to the real time or get some kind of system time event to fire when an second ticks in AS3? Also if I set a Timer to fire every 1000 milliseconds, is that guaranteed or can there be some offset based on the application load? These are probably negligible issues but I'm just curious. Thanks.

  • optimizing iPhone OpenGL ES fill rate

    - by NateS
    I have an Open GL ES game on the iPhone. My framerate is pretty sucky, ~20fps. Using the Xcode OpenGL ES performance tool on an iPhone 3G, it shows: Renderer Utilization: 95% to 99% Tiler Utilization: ~27% I am drawing a lot of pretty large images with a lot of blending. If I reduce the number of images drawn, framerates go from ~20 to ~40, though the performance tool results stay about the same (renderer still maxed). I think I'm being limited by the fill rate of the iPhone 3G, but I'm not sure. My questions are: How can I determine with more granularity where the bottleneck is? That is my biggest problem, I just don't know what is taking all the time. If it is fillrate, is there anything I do to improve it besides just drawing less? I am using texture atlases. I have tried to minimize image binds, though it isn't always possible (drawing order, not everything fits on one 1024x1024 texture, etc). Every frame I do 10 image binds. This seem pretty reasonable, but I could be mistaken. I'm using vertex arrays and glDrawArrays. I don't really have a lot of geometry. I can try to be more precise if needed. Each image is 2 triangles and I try to batch things were possible, though often (maybe half the time) images are drawn with individual glDrawArrays calls. Besides the images, I have ~60 triangles worth of geometry being rendered in ~6 glDrawArrays calls. I often glTranslate before calling glDrawArrays. Would it improve the framerate to switch to VBOs? I don't think it is a huge amount of geometry, but maybe it is faster for other reasons? Are there certain things to watch out for that could reduce performance? Eg, should I avoid glTranslate, glColor4g, etc? I'm using glScissor in a 3 places per frame. Each use consists of 2 glScissor calls, one to set it up, and one to reset it to what it was. I don't know if there is much of a performance impact here. If I used PVRTC would it be able to render faster? Currently all my images are GL_RGBA. I don't have memory issues. Here is a rough idea of what I'm drawing, in this order: 1) Switch to perspective matrix. 2) Draw a full screen background image 3) Draw a full screen image with translucency (this one has a scrolling texture). 4) Draw a few sprites. 5) Switch to ortho matrix. 6) Draw a few sprites. 7) Switch to perspective matrix. 8) Draw sprites and some other textured geometry. 9) Switch to ortho matrix. 10) Draw a few sprites (eg, game HUD). Steps 1-6 draw a bunch of background stuff. 8 draws most of the game content. 10 draws the HUD. As you can see, there are many layers, some of them full screen and some of the sprites are pretty large (1/4 of the screen). The layers use translucency, so I have to draw them in back-to-front order. This is further complicated by needing to draw various layers in ortho and others in perspective. I will gladly provide additional information if reqested. Thanks in advance for any performance tips or general advice on my problem!

  • Why Standards Place Limits on Data Transfer Rates?

    - by Mehrdad
    This is a rather general question about hardware and standards in general: Why do they place limits on data transfer rates, and disallow manufacturers from exceeding those rates? (E.g. 100 Mbit/s for Wireless G, 150 Mbit/s for Wireless N, ...) Why not allow for some sort of handshake protocol, whereby the devices being connected agree upon the maximum throughput that they each support, and use that value instead? Why does there have to be a hard-coded limit, which would require a new standard for every single improvement to a data rate?

  • Games, Windows 8.1 and 144Hz display

    - by Marioysikax
    So I have been having problems with few games after switching from 7 to 8.1, which seems to be related to my 144Hz monitor. Few examples: Shank, Shank 2, Blood of the Werewolf, Astebreed, the Sims 2 and Rayman Legends patch 1.2Had few other as well but it's been long and I have 600+ steam library. From those games at least the Sims 2 and Shank worked without any problems with same setup and Windows 7. So basically these games simply refuse to launch with basic setup. However if I plug 60Hz TV with HDMI instead everything magically starts to work. As for Astebreed and the Sims 2 using windowed mode seems to also work. As for Rayman Demo and version 1.0 works for some reason and 1.2 breaks settings menu. I have already tried contacting supports. EA support stated game simply shouldn't work with 8.1 at all (which is lie as it works with that TV and friend with 8 plays just fine), ubisoft support took few weeks and support said he will forward info for further processing, blood of the werewolf support had no idea what's going on and told me to just use my TV instead.Changing monitors refresh rate to 120Hz or forcing it to 60Hz doesn't do anything. I have DVI right now but I will try with DisplayPort when I get the cable. At PCGW Garrett said it may have something to do how listing resolutions work with 8 compared to earlier Windows versions but my googling skills don't bring anything up and compatibility mode for earlier windows version doesn't work either (not that I expected that to work). My system specs are on my steam profile. How do I get those work with my 144Hz monitor as well as possible future games having same problem? Downgrading to 7 would work but is far from practical and I don't own legit lisence for that one.

  • The clock problem - to if or not to if?

    - by trejder
    Let's say, we have a simple digital clock. To "power" it, we use a routine executed every second. We update seconds part in it. But, what about minutes and hours part? What is better / more professional / offers better performance: Ignore all checking and update hour, minute and seconds part each time, every second. Use if + a variable for checking, if 60 (or 3600) seconds passed and update minute / hour part only at that precise moments. This leads us to a question, what is better -- unnecessary drawings (first approach) or extra ifs? I've just spotted a Javascript digital clock, one of millions similar on one of billions pages. And I noticed that all three parts (hours, minutes and seconds) are updated every second, though first changes its value only once per 3600 seconds and second once per 60 seconds. I'm not to experienced developer, so I might me wrong. But everything, what I've learnt up until now, tells me, that if are far better then executing drawing / refreshing sequences only to draw the same content.

  • How best to calculate derived currency rate conversions using C#/LINQ?

I'm looking for a general purpose algorithm of the form: public double Rate(string baseCode, string targetCode, double currency) { return ... } In the example above a derived rate would be GBP-CHF or EUR-SEK (which would require using the conversions for EUR-USD, USD-CHF, CHF-SEK) Whilst I know how to do the conversions by hand I'm looking for a tidy way (perhaps using LINQ) to perform these derived conversions perhaps involving multiple currency hops, what's the nicest way to go about this?

  • How does Alpha Five Version 10 Rate for Web App Development

    - by Gary B2312321321
    I came across this RDMS via the advert on stackoverflow. Seems to be in the vein of MS Access / Filemaker / Apex database development tools but focused on web based applications. It quotes rave reviews from EWeek and a favourable mention from Dr Dobbs regarding its ability to create AJAX web applications without coding. The Eweek review, apparently written by an ASP.NET programmer, goes on to proclaim the ease at which apps can be extended using the inbuilt XBasic language and how custom javascript can easily be added without wading through code. Has anyone here built a web app with Alpha 5? Does anyone have comments on the development process, the speed of it or limitations they encountered along the way? To me it seems Oracle APEX comes closest to the feature set, has anyone programmed in both and have any comments?

  • Twitter API and rate limiting - I am confused

    - by jeffreyveon
    I am new to the Twitter API, and I looked at their whitelisting policies and I am a little confused... I'm basically writing a twitter aggregrator that crawls the public tweets of a set of users (not more than 200) hourly. I wanted to apply for whitelisting, and they seem to offer account based and IP based whitelisting. Since I am using a shared hosting, my outbound IP address might vary (and twitter does'nt allow IP ranges for whitelisting). So I am considering using account based whitelisting. However, while using OAuth, is it possible for me to use account based whitelisting for a background process that crawls the API hourly?

  • I'm looking for a way to evaluate reading rate in several languages

    - by i30817
    I have a software that is page oriented instead of scrollbar oriented so i can easily count the words, but i'd like a way to filter outliers and some default value for the text language (that is known). The goal is from the remaining text to calculate the remaining time. I'm not sure what is the best unit to use. WPM (words per minute) from here seems very fuzzy and human oriented. Besides i don't know how many "words" remain in the text. http://www.sfsu.edu/~testing/CalReadRate.htm So i came up with this: The user is reading the text. The total text size in characters is known. His position in the text is known. So the remaining characters to read is also known. If a language has a median word length of say 5 chars, then if i had a WPM speed for the user, i could calculate the remaining time. 3 things are needed for this: 1) A table of the median word length of the language. 2) A table of the median WPM of a median user per language. 3) Update the WPM to fit the user as data becomes available, filtering outliers. However i can't find these tables. And i'm not sure how precise it is assuming median word length.
