• Is there a grey-area with Copyright infringement?

  - by Z.O

  Currently a student, I'm trying to put together a game for iOS. From everywhere I've read, it seems any game's sound and art are apart of their IP and covered under their Copyright. That being said, say I wanted to use the coin sound effect from the original Mario (less than 1s long and used sparsely)... would anyone really care? Having no experience with this, I'm just wondering if cases like this are treated like "Ya you're driving slightly over the speed limit, but nobody cares" or as "you stole that car". Thanks for any insight anyone may be able to provide.

• What is the etiquette in negotiating payment for a software development job

  - by EpsilonVector

  The reason I'm taking a general business question and localize it to software development is that I'm curious as to whether there are certain trends/etiquette/nuances that are typical to our industry. For example, I can imagine two different attitudes employers may generally have to payment negotiations: 1) we'll give you the best offer so we can't really be flexible about it because we already pretty much gave you everything we can give you, or 2) we'll give him an average offer and give in to a better one if forced to. If you try to play hard ball in the first attitude it'll probably cost you the job because you ask for more than they can give you, however if you don't insist on better payment in the second one you'll get a worse offer. In short, when applying to a typical job in our industry what are the typical attitudes from employers on the offers they give, what is the correct way to ask for a better payment, do these things differ between different types of companies (for example startups vs well entrenched companies), and how do these things differ between different kinds of applicants (graduate vs student)?

• WIF, ADFS 2 and WCF&ndash;Part 6: Chaining multiple Token Services

  - by Your DisplayName here!

  See the previous posts first. So far we looked at the (simpler) scenario where a client acquires a token from an identity provider and uses that for authentication against a relying party WCF service. Another common scenario is, that the client first requests a token from an identity provider, and then uses this token to request a new token from a Resource STS or a partner’s federation gateway. This sounds complicated, but is actually very easy to achieve using WIF’s WS-Trust client support. The sequence is like this: Request a token from an identity provider. You use some “bootstrap” credential for that like Windows integrated, UserName or a client certificate. The realm used for this request is the identifier of the Resource STS/federation gateway. Use the resulting token to request a new token from the Resource STS/federation gateway. The realm for this request would be the ultimate service you want to talk to. Use this resulting token to authenticate against the ultimate service. Step 1 is very much the same as the code I have shown in the last post. In the following snippet, I use a client certificate to get a token from my STS: private static SecurityToken GetIdPToken() {     var factory = new WSTrustChannelFactory(         new CertificateWSTrustBinding(SecurityMode.TransportWithMessageCredential,         idpEndpoint);     factory.TrustVersion = TrustVersion.WSTrust13;       factory.Credentials.ClientCertificate.SetCertificate(         StoreLocation.CurrentUser,         StoreName.My,         X509FindType.FindBySubjectDistinguishedName,         "CN=Client");       var rst = new RequestSecurityToken     {         RequestType = RequestTypes.Issue,         AppliesTo = new EndpointAddress(rstsRealm),         KeyType = KeyTypes.Symmetric     };       var channel = factory.CreateChannel();     return channel.Issue(rst); } To use a token to request another token is slightly different. First the IssuedTokenWSTrustBinding is used and second the channel factory extension methods are used to send the identity provider token to the Resource STS: private static SecurityToken GetRSTSToken(SecurityToken idpToken) {     var binding = new IssuedTokenWSTrustBinding();     binding.SecurityMode = SecurityMode.TransportWithMessageCredential;       var factory = new WSTrustChannelFactory(         binding,         rstsEndpoint);     factory.TrustVersion = TrustVersion.WSTrust13;     factory.Credentials.SupportInteractive = false;       var rst = new RequestSecurityToken     {         RequestType = RequestTypes.Issue,         AppliesTo = new EndpointAddress(svcRealm),         KeyType = KeyTypes.Symmetric     };       factory.ConfigureChannelFactory();     var channel = factory.CreateChannelWithIssuedToken(idpToken);     return channel.Issue(rst); } For this particular case I chose an ADFS endpoint for issued token authentication (see part 1 for more background). Calling the service now works exactly like I described in my last post. You may now wonder if the same thing can be also achieved using configuration only – absolutely. But there are some gotchas. First of all the configuration files becomes quite complex. As we discussed in part 4, the bindings must be nested for WCF to unwind the token call-stack. But in this case svcutil cannot resolve the first hop since it cannot use metadata to inspect the identity provider. This binding must be supplied manually. The other issue is around the value for the realm/appliesTo when requesting a token for the R-STS. Using the manual approach you have full control over that parameter and you can simply use the R-STS issuer URI. Using the configuration approach, the exact address of the R-STS endpoint will be used. This means that you may have to register multiple R-STS endpoints in the identity provider. Another issue you will run into is, that ADFS does only accepts its configured issuer URI as a known realm by default. You’d have to manually add more audience URIs for the specific endpoints using the ADFS Powershell commandlets. I prefer the “manual” approach. That’s it. Hope this is useful information.

• What is the best currency API out there?

  - by YouBook

  I may be asking an odd question, but webmasters seem like a decent place to post this. I'm in the search for an accurate, easy API (such as using JSON or XML) so I can use my web application. I've been trying Google's secret API, but it's dependency isn't that good because of parsing the string (weird JSON format that PHP sometimes return incorrect data or truncates the string due to parsing error, but Google's API is fair but can be improved. So, all I'm asking is your current best currency API out there, I want to have them to include documented API so I can use it with PHP. Cheers.

• Python: Future as a major programming language?

  - by chrisw

  After reading some Python material and seeing some Python code a few years back I decided to give it a whirl. I decided to start with Python to solve the problems on Project Euler and was throughly impressed with the language. Since then I've went on to learn Django, and now use it primarily for my web applications. I would love to have a career programming in this language, however I fear the future of the language is currently in a state of uncertainness. With Google and other major companies embracing it there may be some hope, what are your thoughts on Python, do you see many job opportunities out there?

• URL good practice for category sub category?

  - by Seting

  I have developed a application and I need to work for SEO-friendly URL. I have following URL structure: http://localhost:3000/posts/product/testing-with-slug-url-2 and http://localhost:3000/posts/product/testing-with-slug-url-2-4-23 Is this a good practice? If not how can I rewrite it? Ok Ill explain about my applicaiton. My application is based on shopping. if a customer searched for mobiles. it will redirect to url like this http://mydomain.com/cat/mobile-3 3 in the url indicates my database id it is used for further searching After the user reached the mobile page he may need to filter for some brand eg. nokia so my url look lik http://mydomain.com/subcat/nokia-3-2 The integer at the end refers to 3 category id and 2 the brand id My doubt is whether the integer at the end of the url will affect seo ranking.

• Can I get any logging and error output from Flash?

  - by Dave M G

  To further provide better information for my other question about browsers and Pulse audio, I wanted to see if I could get some kind of helpful log information. I've looked at logs from both Pulseaudio and Firefox, but don't see anything like an error in either of them. The problem I'm experiencing may be coming from Flash. Is there a way I can trap specifically any log output from Flash? Update: I've downloaded the Linux Flash Player 10.3 Plugin content debugger, and I've installed libflashplayer.so in ~/.mozilla/firefox/plugins/, and copied the user/* files to /user. I've also set up mm.cfg to say: ErrorReportingEnable=1 TraceOutputFileEnable=1 MaxWarnings=50 TraceOutputFileName=/home/dave/.macromedia/Flash_Player/Logs/flashlog.txt And I rebooted just to be sure everything was starting fresh. However, after playing a Flash video from Youtube, flashlog.txt is not being generated. How can I be sure that logging is in fact enabled, so I can tell whether I'm simply not getting errors or I haven't set up logging correctly?

• Resources for improving your comprehension of recursion?

  - by Andrew M

  I know what recursion is (when a patten reoccurs within itself, typically a function that calls itself on one of its lines, after a breakout conditional... right?), and I can understand recursive functions if I study them closely. My problem is, when I see new examples, I'm always initially confused. If I see a loop, or a mapping, zipping, nesting, polymorphic calling, and so on, I know what's going just by looking at it. When I see recursive code, my thought process is usually 'wtf is this?' followed by 'oh it's recursive' followed by 'I guess it must work, if they say it does.' So do you have any tips/plans/resources for building up your skills in this area? Recursion is kind of a wierd concept so I'm thinking the way to tackle it may be equally wierd and inobvious.

• Tips for adapting Date table to Power View forecasting #powerview #powerbi

  - by Marco Russo (SQLBI)

  During the keynote of the PASS Business Analytics Conference, Amir Netz presented the new forecasting capabilities in Power View for Office 365. I immediately tried the new feature (which was immediately available, a welcome surprise in a Microsoft announcement for a new release) and I had several issues trying to use existing data models. The forecasting has a few requirements that are not compatible with the “best practices” commonly used for a calendar table until this announcement. For example, if you have a Year-Month-Day hierarchy and you want to display a line chart aggregating data at the month level, you use a column containing month and year as a string (e.g. May 2014) sorted by a numeric column (such as 201405). Such a column cannot be used in the x-axis of a line chart for forecasting, because you need a date or numeric column. There are also other requirements and I wrote the article Prepare Data for Power View Forecasting in Power BI on SQLBI, describing how to create columns that can be used with the new forecasting capabilities in Power View for Office 365.

• Bad FPS for smaller size (OpenGL ES with SDL)

  - by ber4444

  If you saw my other question, well, there is still a little problem: Click here to watch on youtube Basically, the frame rate is very bad on the actual device, where for some reason the animation is scaled (it looks like the left side on the video). It is quite fast on the simulator where it is not scaled (right side). For a test, I submitted this new changeset that hard-codes the smaller size (plus increases the point size for HII regions to make the dust clouds more visible), and as you see in the video, now it is slow even in the simulator (left side shows the small size, right side shows the original size -- otherwise the code is the same). I'm clueless why it's soooo slow with a smaller galaxy, in fact it should be FASTER. As for general speed optimization (which is not strictly part of my question but is closely related to it, esp. if we need a workaround to speed things up), some initial ideas: reducing the number of items drawn may affect the appearance negatively but screen resolution could be reduced there are too many glBegin(GL_POINTS)/glEnd() blocks, we could draw more than just a single star at once

• Keyboard "type ahead" in CRUD web apps?

  - by user61852

  In some data entry contexts, I've seen data typists, type really fast and know so well the app they use, and have a mechanic quality in their work so that they can "type ahead", ie continue typing and "tab-bing" and "enter-ing" faster than the display updates, so that in many occasions they are typing in the data for the next form before it draws itself. Then when this next entry form appears, their keystrokes fill the text boxes and they continue typing, selecting etc. In contexts like this, this speed is desirable, since this persons are really productive. I think this "type ahead of time" is only possible in desktop apps, but I may be wrong. My question is whether this way of handling the keyboard buffer (which in desktop apps require no extra programming) is achievable in web apps, or is this impossible because of the way web apps work, handle sessions, etc (network latency and the overhead of generating new web pages ) ?

• 4 Alternatives to Google Drive for Linux

  - by Chris Hoffman

  We’ve covered using Google Drive on Linux with third-party software, but why bother jumping through those hoops? You can use a cloud storage service that officially supports Linux instead – several of Google Drive’s competitors do. Google may be leaving Linux users out, but other services like Dropbox, Ubuntu One, SpiderOak, and Wuala don’t ignore Linux users. They even offer more storage and other useful features, such as local encryption of your files.

• Linux for web Development [closed]

  - by Mr.TAMER

  I usually used windows for developing desktop applications, but recently I've almost abandoned desktop apps and have been doing web development so much. I'm using many web technologies and languages, especially Ruby on Rails, and I'm facing too many problems using windows. Besides, I personally want to move to Linux. So, what's the most helpful and comfortable Linux distribution for web development? I have a short but handy experience using Ubuntu desktop, so I'm familiar with the generics of Linux (like -as a simple example- using the command line), and I don't have any problem in getting used to any distribution (I know I may face some difficulties, but again I have no problem), I only want the best one for web development (especially rails!!). If the question doesn't belong to this site, I'll be glad to migrate it to the appropriate one.

• Is code that terminates on a random condition guaranteed to terminate?

  - by Simon Campbell

  If I had a code which terminated based on if a random number generator returned a result (as follows), would it be 100% certain that the code would terminate if it was allowed to run forever. while (random(MAX_NUMBER) != 0): // random returns a random number between 0 and MAX_NUMBER print('Hello World') I am also interested in any distinctions between purely random and the deterministic random that computers generally use. Assume the seed is not able to be known in the case of the deterministic random. Naively it could be suggested that the code will exit, after all every number has some possibility and all of time for that possibility to be exercised. On the other hand it could be argued that there is the random chance it may not ever meet the exit condition-- the generator could generate 1 'randomly' until infinity. (I suppose one would question the validity of the random number generator if it was a deterministic generator returning only 1's 'randomly' though)

• EV SSL Certificates - does anyone care?

  - by pygorex1

  Is any one aware of any data or studies from an impartial source that show the impact of EV SSL certificates on customer behavior? I've been unable to find any such studies. If an EV SSL certificate increases sales on a web store front by even a few points, I can see the value. Aside from data targeted at EV SSL it may be possible to guess at customer behavior based on user interaction with regular SSL certificates. Are users even aware of SSL security? Does regular SSL have any proven effect on web store front sales? Note, that I'm not asking about the necessity of good encryption - I'm asking about a potential customer's perception of security & trust.

Within Windows 7, launch my real install of ubuntu as if it were a VM. That means i would get all the installed software, all of the files, and all of the settings. Launch a VM copy of ubuntu 10.04 but some how make it use all of the installed software and settings from my real copy. Thanks!

• How to design a replay system

  - by daddz

  So how would I design a replay system? You may know it from certain games like Warcraft 3 or Starcraft where you can watch the game again after it has been played already. You end up with a relatively small replay file. So my questions are: How to save the data? (custom format?) (small filesize) What shall be saved? How to make it generic so it can be used in other games to record a time period (and not a complete match for example)? Make it possible to forward and rewind (WC3 couldn't rewind as far as I remember)

• Multi-lingual error messages and error numbers

  - by Jon Hopkins

  So we're looking at the possibility of porting our software to support multiple languages and one of the areas we're going to have to deal with is error messages and other notifications. These obviously have to be reported to the users in their own language. Our team (largely) only speak English and even if we were all multi-lingual we're looking at selling to a wide range of countries and could never expect to have a reasonable number of people speaking all languages (we're a small company). The obvious way to get round the language issue when errors or other messages we may get asked about which are being reported is error numbers which would be consistent across language. While these are going to exist in the backend (if only as key on the error message), I'd really rather not throw them at users if we don't have to but I don't have any other solution. Anyone have any useful suggestions for alternatives?

• A Quantity class with units

  - by Ryan Ohs

  Goals Create a class that associates a numeric quantity with a unit of measurement. Provide support for simple arithmetic and comparison operations. Implementation An immutable class (Could have been struct but I may try inheritance later) Unit is stored in an enumeration Supported operations: Addition w/ like units Subtraction w/ like units Multiplication by scalar Division by scalar Modulus by scalar Equals() >, >=, <, <=, == IComparable ToString() Implicit cast to Decimal The Source The souce can be downloaded from Github. Notes This class does not support any arithmetic that would modify the unit. This class is not suitable for manipulating currencies. Future Ideas Have a CompositeQuantity class that would allow quantities with unlike units to be combined. Similar currency class with support for allocations/distributions. Provide conversion between units. (Actually I think this would be best placed in an external service. Many situations I deal with require some sort of dynamic conversion ratio.)

• Connect to new wireless network
