  • Fastest bit-blit in C# ?

    - by AttackingHobo
    I know there is Unity, and XNA that both use C#, but I am don't know what else I could use. The reason I say C# is that the syntax and style is similar to AS3, which I am familiar with, and I want to choose the correct framework to start learning with. What should I use to be able to do the most possible bit-blit(direct pixel copy) objects per frame. EDIT: I should not need to add this, but I am looking for the most possible amount of objects per frame because I am making a few Bullet-Hell SHMUPS. I need thousands and thousands of bullets, particles, and hundreds of enemies on the screen at once. I am looking for a solution to do as many bit-blit operations per frame, I am not looking for a general purpose engine. EDIT2: I want bit-blitting because I do not want to exclude people who have lower end video cards but a fast processor from playing my games.

  • Has programming ruined your perception of round numbers?

    - by Jon Purdy
    Most of the world works in base 10 nowadays, but as programmers working on binary systems, we constantly find ourselves working with powers of 2. While most people consider integer multiples of powers of 10 "nice and round" and somehow aesthetically superior, I found early on in my programming adventures that multiples of powers of 2 feel much more intuitively round to me: fewer factors, of course. I'm much more likely to lay out a Web site using, say, 8- or 16-pixel margins rather than 10 or 20, and when someone remarks that 128 is an insanely arbitrary number of ounces to be in a gallon, I have to smile a little inside at how, just perhaps, the U.S. system might be superior to metric in one small way. I'm just curious: has programming ruined (read: altered) your perception of the roundness of a number?

  • Apple New Year alarm bug cause

    - by StasM
    As many people know, Apple has a bug in their iPhone that prevented alarms from going off at 1st and 2nd of January 2011. What is strange is how that bug might happen - i.e., as far as I know this bug happens in all timezones and nobody is switching off DST on Jan 1st, so it's not timezone or DST-related. Also, Jan 1st seems to be nothing special as a UNIX timestamp, so something like sign change or integer overflow can't be the reason. It is highly improbably that alarm code has something like if(date == JANUARY_1_2011 || date == JANUARY_2_2011) turn_alarms_off(); - that would be a sabotage and not a bug. So the question is - could you imagine and describe a bug that would cause the alarm to fail exactly at Jan 1st and 2nd everywhere while letting it work otherwise, without specifically referring to those exact dates? Of course, if somebody knows the real cause, that would be a definite answer, but if nobody knows it - I think it is interesting to think what might be the cause of such strange bug.

  • #altnetseattle in Closing

    - by GeekAgilistMercenary
    So again, the #altnetseattle Conference easily was one of the most useful events of the year for me.  The amount of ideas, thoughts, and conversations that happen in just those two days often outweigh all the presentations I see at other conferences throughout the year.  The reason is simple, they are directed, to the point, and done with the ideal of open spaces.  This makes each session exhaustive on a particular topics.  Throw together some of the smartest people in the field and you have a bang up awesome energy and conversation. I got to talk about cloud computer, a little bit, and REST Architecture as sessions I kicked off myself.  Those were a blast.  I also got to meet a ton of other super talented like minded developers and engineers that are out there kicking the tires of .NET (and other languages/tech stacks like Ruby on Rails). Overall the conference rocked and I will definitely be coming back!  With that, I am headed home to Portland.

  • Why do some opensouce libraries lack comments?

    - by entropy
    I don't know if this happens to most Opensource libraries, but many of I know and use (for example OpenSSL, Webkit, ...) they all lack comments, or contain very few comments. Not to mention their very few documents, it is hard to read their source code. We can hardly understand what a member variable means, or what this function does. This seems to be against coding standard practice Why is that? How can people collaborate to these opensource with very few comments?

  • Web technologies on GUI apps

    - by Apalala
    I developed many GUI applications for the Windows platform during my early professional career, and saw several GUI frameworks come, have whole magazines devoted to them, and then fade away. MFC is iconic. Tasked with writing yet another GUI application, I starter researching cross-platform frameworks like Qt and WxWindows. I found the same steep learning curves I knew from before, and tooling doesn't help much in building a functional and elegant user interface because its clumsy and complicated. But people are building beautiful and functional UIs on the Web all the time (look at this site!). The standards, the libraries, and the tools are certainly there. My thought and my question: Why not write a GUI in which most of the UI is handled by an embedded browser? I already know that the Qt widgets support a large part of CSS and JavaScript, and programmers with good knowledge about web development are relatively easy to find, ..., so... Have you done something like that before? What's your experience/advise?

  • Ideas for making money off a website

    - by bradenkeith
    I'm considering acquiring a website that traffics close to 20k a month. It's currently unprofitable, but obviously I would need to change that to justify the cost. It's a support site for a framework similar to CakePHP. A resource that allows people to find plugins for that site. How would you go about expanding this site so that it would be broad enough to raise traffic and how would you make money off of it? Some ideas I've had: 1- BuySellAds.com seem to make ads classy and relevant 2- Team up with other sites in some way (What ways? ... Ecommerce sites that sell plugins (like CodeCanyon), etc) 3- Write tutorials and such to drive more traffic (time consuming, and already heavily saturated for this framework). Are there resources out there that help webmasters in ways like this?

  • If PHP websites represnt 70% of websites in my country then should I learn it?

    - by Fadi Tiwari
    In my country most of the sites are built using PHP and MySQL. Half of those sites use vbulletin and Wordpress. When it comes to companies, ministries and universities they use ASP.NET. I am not sure what should I learn to get more money as freelacer? Should I learn ASP.NET and focus my area to build companies and universities' sites? (And the question if they will know me one day and ask me to build any of their sites or not?) Or should I learn PHP and focus my business on people's sites and maybe some small formal sites? Which option will give me more money?

  • Google SMTP relay sending limits

    - by Gavin
    I'm considering using Google Apps for email with my company domain and for sending emails to customers from my website using SMTP. On Google's website it says the following: Limits for registered Google Apps users A registered Google Apps user cannot relay messages to more than 2,000 recipients per day. Limits per domain Per-domain sending limits are determined by the number of users in your Google Apps account. There are two per-domain limits: The maximum number of recipients allowed per domain per day is approximately 130 times the number of users in your Google Apps account. The maximum number of recipients allowed per domain in a 10 minute window is approximately 9 times the number of users in your Google Apps account. Additionally, the maximum number of recipients allowed per domain per day for accounts not yet paid for during the first month of service is 100. If I'm a single user, with a single domain, then does that mean I can only email 130 people a day using SMTP? That limit seems low.

  • Moving AI in a multiplayer game

    - by Smallbro
    I've been programming a multiplayer game and its coming together very nicely. It uses both TCP and UDP (UDP for movement and TCP for just about everything else). What I was wondering was how I would go about sending multiple moving AI without much lag. At first I used TCP for everything and it was very slow when people moved. I'm currently using a butchered version of this http://corvstudios.com/tutorials/udpMultiplayer.php for my movement system and I'm wondering what the best method of sending AI movements is. By movements I mean the AI chooses left/right/up/down and the player can see this happening. Thanks.

  • Directory paths for resources and assets

    - by The Communist Duck
    If I have a file stucture for my final, released game something like: Main folder Media Images Other assets Sounds Executable List item And a different one for my 'in development' project, with the same Media folder but: Main Source and .obj, etc. Media with everything Bin folder with executable I obviously cannot hardcode file pathnames into this, like: "../Media/Image/evilguy.png" or "Media/Image/foo.jpg" because they wouldn't work with one of the builds and would require a lot of switching names. Instead, does it make sense for my resource manager, that loads everything, to have some kind of prefix path? Then, I can just do Get("foo.jpg") or Get("Sounds/boom.ogg") And simply switch out, for the final release, the ctr argument from the relative path for the development build to the release layout? If not, how have other people sorted these sorts of things out?

  • Got an idea for an application, but part of it is patented, any suggestions?

    - by tekiegreg
    so I've been working on developing an idea for an application that I think has the potential to be successful, however after some initial research I've discovered that at least part of my ideas are covered by a patent out there, the patent in particular is held by a really large company (I don't want to give away specifics for fear I'd draw their attention for sure). I'm debating a few options: 1) Develop patents around my ideas that don't conflict and maybe approach the company in question for a license exchange 2) Just approach them for a license outright 3) Just develop around it anyways and hope for the best :-p What have other people done in these situations? Are companies generally willing to grant patent licenses? Are they willing to grant them at reasonable prices? Thoughts?

  • SEO and Spelling mistakes in keyword

    - by Sushil
    I am about to register a domain name (suppose) someone.com (with proper spelling), in mind targeting the keyword "SOMEONE". But then I discovered on 'google keyword research tool' that not this but a typo "SOME1" seems to be more popular and people search this significantly more often than the proper keyword. And luckily someone.com and some1.com both are available. I understand that I can register both the domains, but I don't know on which should I keep my website and redirect the other one. Should I make the typo "some1.com" my base site? But that's a typo. P.S., my site has a totally relevant content and not just keyword targeted worthless site. What do you guys suggest? I am confused. How would that affect my SEO ranking?? EDIT: Because the competition for the keyword I am targeting is fairly low, I think nevertheless whatever domain I choose, it will appear on the search engine first page.

  • Shortest Common Superstring: find shortest string that contains all given string fragments

    - by occulus
    Given some string fragments, I would like to find the shortest possible single string ("output string") that contains all the fragments. Fragments can overlap each other in the output string. Example: For the string fragments: BCDA AGF ABC The following output string contains all fragments, and was made by naive appending: BCDAAGFABC However this output string is better (shorter), as it employs overlaps: ABCDAGF ^ ABC ^ BCDA ^ AGF I'm looking for algorithms for this problem. It's not absolutely important to find the strictly shortest output string, but the shorter the better. I'm looking for an algorithm better than the obvious naive one that would try appending all permutations of the input fragments and removing overlaps (which would appear to be NP-Complete). I've started work on a solution and it's proving quite interesting; I'd like to see what other people might come up with. I'll add my work-in-progress to this question in a while.

  • T-SQL Tuesday #36 (#tsql2sday)– Post-PASS Summit Depression

    - by Argenis
    I had an email thread going with a prominent member of the SQL Server community today, where he confessed that he didn’t attend any sessions during the PASS Summit last week. He spent all of this time networking and catching up with people. I, personally, can relate. This year’s Summit was another incarnation of that ritual of SQL Server professionals meeting to share their knowledge, experience, and just have a wonderful time while doing so. It’s been a few days after the Summit is over, and I’m definitely dealing with withdrawal. My name is Argenis, and I’m a #SQLFamilyHolic.         (This post is part of the T-SQL Tuesday series, a monthly series of blog posts from members of the SQL Server community – this month, Chris Yates is hosting)

  • How to add a holding page in front of a domain

    - by Jason Bradberry
    I have set up a holding page to announce a new version of a website coming soon. I wanted people to still be able to access the original site, so my approach was to place the holding page in the root folder on the server, and move the original site to a subfolder and link to it from the holding page. However, on testing this setup it appears to have hurt the SEO placing of the website. Is there a better approach to this? I'm a bit stumped as I want both to share the same URL.

  • The SQL Server Community

    - by AllenMWhite
    In case you weren't aware of it, I absolutely love the SQL Server community. The people I've gotten to know have amazing knowledge, and they love sharing that knowledge with anyone who wants to learn. How can you not love that? It's inspiring and humbling all at the same time. There are a number of venues where the SQL Server community comes together. I'm including Twitter , the PASS Summit , the various SQL Saturday events, SQLBits , Tech Ed , and the local user groups. Each of us takes part in...(read more)

  • Does schema.org improve SEO?

    - by marko
    http://schema.org This site provides a collection of schemas, i.e., html tags, that webmasters can use to markup their pages in ways recognized by major search providers. Search engines including Bing, Google, Yahoo! and Yandex rely on this markup to improve the display of search results, making it easier for people to find the right web pages. It sounds wonderful, but does the search spider ignore the extra attributes and elements? Is it just too clever and ignores it? May it also be that it lowers your visibility because of such alteration?

  • Extension Manager in Visual Studio 2010

    One of the powerful aspect of Visual Studio is its ability to be extended and many people do that. You can find numerous extensions at the Visual Studio Gallery. The VSX team links to a 4-part blog series on how to create and share templates. You can also look find extension examples on the vsx code gallery.With Visual Studio 2010, you can search for items and install them directly from within Visual Studio's new Extension Manager. You launch it from the Tools menu:When the dialog comes up, be sure to explore the various actionable areas on the left and also note the search on the right. For example, I typed "MP" and it quickly filtered the list to show me the MPI Project Template:Others have written about this before me, just bing Extension Manager (and note that Beta2 introduced changes, some of which you can witness in the screenshot above). Comments about this post welcome at the original blog.

  • Are RSS feeds used? [closed]

    - by acidzombie24
    I was thinking about implementing RSS feeds on my site. The one thing that came to mind is Are RSS feeds ever used?! I don't use them nor know anyone who does. I know to use them it must be through an rss feed program or built in with the browser. I like my browser clean and i know many ppl dont know how to use/configure their browser. So with my thoughts i deducted that rss are not used 99.9999% of people (thats 4 decimal places which is really saying something). Now twitter on the other hand or even email may be used. But I have doubts about rss feeds. Can anyone give me statistics or change my mind on implementing it? I suspect it would be simple but i dont think i should bother if no one will ever use it. I dont even use SE/SO RSS feeds.

  • Google analytics: how many visitors have visited n times?

    - by Riley
    I'm trying to guess how many loyal users I have by counting the number of people that have visited the site 10 times. How can I answer this question with Google Analytics? "Visitor Loyalty" is a tempting answer, but the label for loyalty is "Visits that were the visitor's nth visit," and I want something more like "Visitors that visited n times." For example, we have 40 visits in the "51-100" visit range, but I think that could be a single user who visited 91 times. Or two users who visited 71 times each. The whole chart makes a good logic puzzle (I wonder if there's a unique solution) but doesn't easily answer the question I have.

  • Best solution for a team home server

    - by aliasbody
    I created a home server with Ubuntu 12.04 Server (using an old Netbook with an Atom CPU and 512Mb). The idea is just to be used for a small team (maximum 10 persons) that will have constant access by SSH to the main projects and could add features with Git, and will, as well, have their own directory (with VirtualHost configured) for their own personal projects. Everything is configured and running, but my question is : What is the best solution here for everyone to work? It is to have them on the http group and then all have access as normal users to the /var/www folder (that also contains GitWeb and Drupal), or would be to create a new user named after the project (as an example) where only those with the password could have access to work (configured with VirtualHost). Notice: The idea is to have 1 person responsible of the server directly (since he is the one who is hosting it), 2 more people that will have access to the root from their home in order to configure anything from their home, plus anyone else that joins the group without any root access, but just the necessary access to create personal works and work with Git.

  • What is the most effective order to learn SQL Server, LINQ, and Entity Framework?

    - by user1525474
    I am trying to get some advice on what order I should learn about SQL Server, LINQ, and Entity Framework to be able to better work with ASP.NET Webforms and MVC. From what I've been able to learn so far, many recommend learning LINQ or Entity Framework before learning SQL Server. It also appears that many companies are looking for people with knowledge in LINQ-to-SQL and Entity Framework without mentioning SQL Server. However, my understanding is that LINQ-to-SQL and Entity Framework translate code into SQL Server queries, making this a poor approach. Is there a correct or best order in which to learn these technologies?
