• Getting Internet Explorer to Open Different Sets of Tabs Based on the Day of the Week

  - by Akemi Iwaya

  If you have to use Internet Explorer for work and need to open a different set of work-specific tabs every day, is there a quick and easy way to do it instead of opening each one individually? Today’s Question & Answer session comes to us courtesy of SuperUser—a subdivision of Stack Exchange, a community-driven grouping of Q&A web sites. The Question SuperUser reader bobSmith1432 is looking for a quick and easy way to open different daily sets of tabs in Internet Explorer for his work: When I open Internet Explorer on different days of the week, I want different tabs to be opened automatically. I have to run different reports for work each day of the week and it takes a lot of time to open the 5-10 tabs I use to run the reports. It would be a lot faster if, when I open Internet Explorer, the tabs I needed would automatically load and be ready. Is there a way to open 5-10 different tabs in Internet Explorer depending on the day of the week? Example: Monday – 6 Accounting Pages Tuesday – 7 Billing Pages Wednesday – 5 HR Pages Thursday – 10 Schedule Pages Friday – 8 Work Summary/Order Pages Is there an easier way for Bob to get all those tabs to load and be ready to go each day instead of opening them individually every time? The Answer SuperUser contributor Julian Knight has a simple, non-script solution for us: Rather than trying the brute force method, how about a work around? Open up each set of tabs either in different windows, or one set at a time, and save all tabs to bookmark folders. Put the folders on the bookmark toolbar for ease of access. Each day, right-click on the appropriate folder and click on ‘Open in tab group’ to open all the tabs. You could put all the day folders into a top-level folder to save space if you want, but at the expense of an extra click to get to them. If you really must go further, you need to write a program or script to drive Internet Explorer. The easiest way is probably writing a PowerShell script. Special Note: There are various scripts shared on the discussion page as well, so the solution shown above is just one possibility out of many. If you love the idea of using scripts for a function like this, then make sure to browse on over to the discussion page to see the various ones SuperUser members have shared!

• Game development: “Play Now” via website vs. download & install

  - by Inside

  Heyo, I've spent some time looking over the various threads here on gamedev and also on the regular stackoverflow and while I saw a lot of posts and threads regarding various engines that could be used in game development, I haven't seen very much discussion regarding the various platforms that they can be used on. In particular, I'm talking about browser games vs. desktop games. I want to develop a simple 3D networked multiplayer game - roughly on the graphics level of Paper Mario and gameplay with roughly the same level of interaction as a hack & slash action/adventure game - and I'm having a hard time deciding what platform I want to target with it. I have some experience with using C++/Ogre3D and Python/Panda3D (and also some synchronized/networked programming), but I'm wondering if it's worth it to spend the extra time to learn another language and another engine/toolkit just so that the game can be played in a browser window (I'm looking at jMonkeyEngine right now). For simple & short games the newgrounds approach (go to the site, click "play now", instant gratification) seems to work well. What about for more complex games? Is there a point where the complexity of a game is enough for people to say "ok, I'm going to download and play that"? Is it worth it to go with engines that are less-mature, have less documentation, have fewer features, and smaller communities* just so that a (possibly?) larger audience can be reached? Does it make sense to even go with a web-environment for the kind of game that I want to make? Does anyone have any experiences with decisions like this? Thanks! (* With the exception of flash-based engines it seems like most of the other approaches have these downsides when compared to what is available for desktop-based environments. I'd go with flash, but I'm worried that flash's 3D capabilities aren't mature enough right now to do what I want easily. There's also Unity3D, but I'm not sure how I feel about that at all. It seems highly polished, but requires a plugin to be downloaded for the game to be played -- at that rate I might as well have players download my game.)

• How to get quality sprite sheet generation with rotations

  - by BenMaddox

  I'm working on a game that uses sprite sheets with rotation for animations. While the effect is pretty good, the quality of the rotations is somewhat lacking. I exported a flash animation to png sequence and then used a C# app to do matrix based rotations (System.Drawing.Drawing2D.Matrix). Unfortunately, there are several places where the image gets clipped. What would you suggest for a way to get high quality rotations from either flash or the exported PNGs? A circle should fit within the same image boundaries. I don't mind a new program that I must write or an existing program I must download/buy.

• LibreOffice: Open in current program by default?

  - by David Oneill

  I often need to open pipe delimited .txt files in LibreOffice Calc. However, once I have Calc running, if I do File Open and select a spreadsheet with the extension .txt, it opens it in Writer instead. Is there a way to tell the file I'm trying to open using whatever program instead of trying to pick which one to use? Barring that, is there a way I tell it to always use Calc for .txt files (when I open them from the open dialog in Calc)? I still want them to open in GEdit like they currently do if I double click them from Thunar.

• How can I create tiles that scale to multiple resolutions?

  - by Darestium

  I am trying to create a multiplayer version of the popular Flash game N in Java. However, I'm not sure how to create a tileset that will scale up. Are the tiles for N pre-drawn or are they defined with mathamatical formulas in code? I do see how they would scale up in Flash if they were pre-rendered. So if anyone has any ideas how I should go about creating the tileset, or how they are created in the game please let me know. You can check out the game here.

• Google displaying swf menu in SiteLinks

  - by m90

  I have a website that uses a Flash based menu as its main navigation. A plain HTML fallback version is "lying underneath", the swf is embedded using swfobject. swfobject.embedSWF('MENU.swf', 'menu', '1000', '600', '8.0.0', 'ext/expressInstall.swf', {}, {wmode:'transparent',bgcolor:'#666666'}, {}); Somehow Google now started displaying a link to the swf-file in the SiteLinks (noting [SWF] beforehand) which is pretty ugly as the Flash content gets all scrambled and all you see is a random string of characters and numbers (it looks "hacked" to me, although I do know it is not). Also, the link to the swf is plain useless as it relies on JavaScript-functions in the HTML-document. I already demoted the swf in the Webmaster Tools, yet in some situations the link will still show up. Is anyone aware of this problem (I haven't found too much on this on the Internet) and knows how I can keep the search results from linking to the swf?

• OpenBSD has open ports in default installation

  - by celil

  I have been considering replacing Ubuntu with OpenBSD to improve the security on my local server. I need to have ssh access to it, and I also need it to serve static web content - so the only ports I need open are 22 and 80. However, when I scan my server for open ports after installing OpenBSD 4.8, and enabling ssh and http at /etc/rc.conf httpd_flags="" sshd_flags="" I discovered that it had several other open ports: Port Scan has started… Port Scanning host: 192.168.56.102 Open TCP Port: 13 daytime Open TCP Port: 22 ssh Open TCP Port: 37 time Open TCP Port: 80 http Open TCP Port: 113 ident ssh (22) and http (80) should be open as I enabled httpd and sshd, but why are the other ports open, and should I worry about them creating additional security vulnerabilities? Should they be open in a default installation?

• What is the standard way of delivering HTML5 games to portals and such?

  - by Bane

  Let me explain what I mean by "standard way of delivering"... Think about Flash games sites. Flash games can be delivered as a single file, either hosted by the site, or, I guess, provided by someone else. HTML5 games, on the other hand, don't have something so standard. Usually, they have their own page, and portals just link to that page. I think that it greatly hinders the purpose of that portal, because, well, you want people to stay on your site and look for other games. Now, I think that a some kind of iframe way of delivering games would help solve this problem greatly. I saw some games doing that, and they were often included on tutorial sites to show a live example, which is obviously a great thing. So, is there a standard at all? Any suggestions? Can you create a game that just preloads itself in an iframe (I heard something about a "single document" or something)?

• Are there Negative Impact of opensource on commercial environment?

  - by Lostsoul

  I know this is not a good fit for Stack Overflow but wasn't sure if it was good for this site also so let me know if its not and I'll delete it. I love programming for fun but my role in my company is not technical. I have always loved the hacker culture and have been trying to drive that openness within my company from day one. My company has a very broad range of products and there are a few that are not strategic to us so I wanted to open source them (so we can focus on what makes us unique and open source the products that every firm has). Our industry does not open source(we would be the first firm to try this) and the feedback I'm getting from my management team is either 1) we'll destroy the industry or 2) all competitive commercial firms will unite against us and we'll be wiped out either way. I disagreed on both points because I think transparency will only grow our industry and our firm (think of McDonalds/KFC sharing their recipe openly, people may copy you, competitors may target you, but customers also may feel more comfortable buying your product. The value add, I believe, is in the delivery and experience not in hoarding the recipe). It's a big battle in my firm right now between the IT people who have seen the positive effects of sharing and the business people who think we'll be giving up everything (they prefer we sell parts we want to opensource, but in their defense this is standard when divesting something). Our industry is very secretive and I don't want to put anyone(even my competitors employees) out of a job yet I don't want to protect inefficient people by not being open with everyone. Yet I've seen so many amazing technologies created in interesting ways just by giving people freedom to take apart code and put it back together. I'm interested in hearing people's thoughts(doesn't have to be to my specific situation, I'm looking for the general lessons). Its a very stressful decision(but one I feel I must make) because if we go the open source route then there will be no going back. So what are your thoughts? Does open sourcing apply generally or is it only really applicable to software? Is it overall good for people in the industry and outside? I'm actually more interested in the negativeness effects(although positive are welcomed as well) Update: Long story short, although code is involved this is not so much about code as it is more about the idea of open sourcing. We are a mid sized quant hedge fund. We have some unique strategies but also have the standard long/short, arbitrage, global macro, etc.. funds. We are keeping the unique funds we have but the other stuff that everyone else has we are considering open sourcing (We have put in years of work & millions of dollars into. Our funds is pretty popular and our performance is either in first or second quartile so I suspect there will be interest but I don't know to what extent). The goal is not to get a community to work for us or anything, the goal is to let anyone who wants to tinker with it do so and create anything they want (it will not be part of our product line although I may unofficially allocate some our of staff's time to assist any community that grows). Although the code base is quite large, the value in this is the industry knowledge and approaches we have acquired (there are many books on artificial intelligence and quant trading but they are often years behind what's really going on as most firms forbid their staff from discussing what they are doing). We are also considering after we move our clients out to let the software still run and output the resulting portfolios for free as well so people can at least see the results(as long as we have avail. infrastructure). I think our main choices are, we can continue to fight for market share in a products that are becoming commoditized, we can shut the funds/products down(and keep the code but no one outside of our firm will ever learn from it) or we can open source it and let people do what they want. By open sourcing it, my idea is that the talent pool in the industry will grow because right now most of our hires have the same background (CFA, MBA, similar school, same experience,etc.. because we can't spend time training people so the industry 'standardizes' most people and thus the firms themselves start to look/act similar) but this may allow us to identify talent that has never been in the industry before (if we put a GPU license then as people learn from what we did, we can learn from what they do as well and maybe apply it to other areas of our firm). I see a lot of benefits but not many negatives while my peers at the company see the opposite.

• Youtube controls (sound, etc) not functional in full-screen mode: is that normal?

  - by mlvljr

  When playing youtube videos full-screen, I can't mouse-interact with the player controls, except for the slider (only single-clicking on the video works as play/pause, but not double-click, interestingly, so the only way to leave full-screen mode is via Escape). Is this behavior known? What can I do about it? I'm on Ubuntu 12.04, using Google's Chrome browser. P.S. If that matters, some other flash players I've tried also display the same problem, so this may be an issue with Google-supplied Flash plugin. Thanks in advance.

• Code golf: Word frequency chart

  - by ChristopheD

  The challenge: Build an ASCII chart of the most commonly used words in a given text. The rules: Only accept a-z and A-Z (alphabetic characters) as part of a word. Ignore casing (She == she for our purpose). Ignore the following words (quite arbitary, I know): the, and, of, to, a, i, it, in, or, is Clarification: considering don't: this would be taken as 2 different 'words' in the ranges a-z and A-Z: (don and t). Optionally (it's too late to be formally changing the specifications now) you may choose to drop all single-letter 'words' (this could potentially make for a shortening of the ignore list too). Parse a given text (read a file specified via command line arguments or piped in; presume us-ascii) and build us a word frequency chart with the following characteristics: Display the chart (also see the example below) for the 22 most common words (ordered by descending frequency). The bar width represents the number of occurences (frequency) of the word (proportionally). Append one space and print the word. Make sure these bars (plus space-word-space) always fit: bar + [space] + word + [space] should be always <= 80 characters (make sure you account for possible differing bar and word lenghts: e.g.: the second most common word could be a lot longer then the first while not differing so much in frequency). Maximize bar width within these constraints and scale the bars appropriately (according to the frequencies they represent). An example: The text for the example can be found here (Alice's Adventures in Wonderland, by Lewis Carroll). This specific text would yield the following chart: _________________________________________________________________________ |_________________________________________________________________________| she |_______________________________________________________________| you |____________________________________________________________| said |____________________________________________________| alice |______________________________________________| was |__________________________________________| that |___________________________________| as |_______________________________| her |____________________________| with |____________________________| at |___________________________| s |___________________________| t |_________________________| on |_________________________| all |______________________| this |______________________| for |______________________| had |_____________________| but |____________________| be |____________________| not |___________________| they |__________________| so For your information: these are the frequencies the above chart is built upon: [('she', 553), ('you', 481), ('said', 462), ('alice', 403), ('was', 358), ('that ', 330), ('as', 274), ('her', 248), ('with', 227), ('at', 227), ('s', 219), ('t' , 218), ('on', 204), ('all', 200), ('this', 181), ('for', 179), ('had', 178), (' but', 175), ('be', 167), ('not', 166), ('they', 155), ('so', 152)] A second example (to check if you implemented the complete spec): Replace every occurence of you in the linked Alice in Wonderland file with superlongstringstring: ________________________________________________________________ |________________________________________________________________| she |_______________________________________________________| superlongstringstring |_____________________________________________________| said |______________________________________________| alice |________________________________________| was |_____________________________________| that |______________________________| as |___________________________| her |_________________________| with |_________________________| at |________________________| s |________________________| t |______________________| on |_____________________| all |___________________| this |___________________| for |___________________| had |__________________| but |_________________| be |_________________| not |________________| they |________________| so The winner: Shortest solution (by character count, per language). Have fun! Edit: Table summarizing the results so far (2012-02-15) (originally added by user Nas Banov): Language Relaxed Strict ========= ======= ====== GolfScript 130 143 Perl 185 Windows PowerShell 148 199 Mathematica 199 Ruby 185 205 Unix Toolchain 194 228 Python 183 243 Clojure 282 Scala 311 Haskell 333 Awk 336 R 298 Javascript 304 354 Groovy 321 Matlab 404 C# 422 Smalltalk 386 PHP 450 F# 452 TSQL 483 507 The numbers represent the length of the shortest solution in a specific language. "Strict" refers to a solution that implements the spec completely (draws |____| bars, closes the first bar on top with a ____ line, accounts for the possibility of long words with high frequency etc). "Relaxed" means some liberties were taken to shorten to solution. Only solutions shorter then 500 characters are included. The list of languages is sorted by the length of the 'strict' solution. 'Unix Toolchain' is used to signify various solutions that use traditional *nix shell plus a mix of tools (like grep, tr, sort, uniq, head, perl, awk).

A weak charge will allow a strong current to flow through. Similar to HDDs, flash memory must provide: Bit error correction Bad block management NAND and NOR memories are treated differently when it comes to managing wear In many NOR-based systems no management is used at all, since the NOR is simply used to store code, and data is stored in other devices. In this case, it would take a near-infinite amount of time for wear to become an issue since the only time the chip would see an erase/write cycle is when the code in the system is being upgraded, which rarely if ever happens over the life of a typical system. NAND is usually found in very different application than is NOR Flash memory wears out This is expected to get worse over time Retention: Disappearing data Bits fade away Retention decreases with increasing read/writes Bits may change when adjacent bits are read Time and traffic are concerns Controllers typically groom read disturb errors Like DRAM refresh Increases erase/write frequency Application characteristics Music – reads high / writes very low Video – r high / writes very low Internet Cache – r high / writes low On airplanes Many consumers now have their own content viewing devices – do they need the airlines?

Is there a way to leverage personal and airline viewers and content in new and entertaining ways?

• Excel - graphing mean and standard deviation

  - by joe_shmoe

  Hi all, I have measurements for multiple devices, and have their mean and sd values. I would like to produce a chart that would show these values, and I think the best would be if I could have something that looks like a bar chart(-ish) - the device names in x axis, values in y axis, and for each device to have a 'floating' bar that would represent values (mean - sd :: mean + sd), and some marker in the middle to show the actual mean value. is it doable? or would you suggest some other chart? Thanks a lot

• Close Flash Player from FlashDevelop IDE

  Whenever I compile my project using FlashDevelop in 'Debug' the Flash Player window remains after I have clicked the 'Stop' button in Flash Develop. I have to then switch over to the flash player, click through any error messages and then close the player, which wastes a lot of time in the long run. Any way to make it so Flash Player closes when I click 'Stop' in the Flash Develop debug tools? EDIT: My setup is a fresh install of Windows 7, a new copy of Flash Develop 4 and Flash Player 10.

• Having trouble with Flash, Javascript and JQuery

  - by andypants

  I'm using JQuery with the JQuery flash plugin (http://jquery.lukelutman.com/plugins/flash/) and trying to send a JS call back to the flash, I keep running into "xxx is not a function" so apparently something is off. I'm new to JQuery and very new to this jquery flash plugin and just can't quite wrap my head around what I am doing wrong. Here's where I'm lading up the flash: <div id="tagimgback"> <script language="javascript"> $(document).ready(function(){ $('#tagflash').flash( { src: 'tagflash', width: 200, height: 200, flashvars: {theYear:'2010',theTagNumber:'123'} }, { version: 8 } ); }); </script> </div> And here's where I'm trying to call it: $("#tagflash").gotoNewFrame(theTagNumber); gotoNewFrame is an AS function within my flash. I know the function works as I've been able to test it prior to bringing jQuery into the mix.

• Daylight Saving Time Visualized

  - by Jason Fitzpatrick

  When you map out the Daylight Saving Time adjusted sunrise and sunset times over the course of the year, an interesting pattern emerges. Chart designer Germanium writes: I tried to come up with the reason for the daylight saving time change by just looking at the data for sunset and sunrise times. The figure represents sunset and sunrise times thought the year. It shows that the daylight saving time change marked by the lines (DLS) is keeping the sunrise time pretty much constant throughout the whole year, while making the sunset time change a lot. The spread of sunrise times as measured by the standard deviation is 42 minutes, which means that the sunrise time changes within that range the whole year, while the standard deviation for the sunset times is 1:30 hours. Whatever the argument for doing this is, it’s pretty clear that reason is to keep the sunrise time constant. You can read more about the controversial history of Daylight Saving Time here.

• .NET WPF Charting Control

  - by Randy Minder

  We're very close to wrapping up a WPF dashboarding application using SSRS (.RDLC files) and the Microsoft Report Viewer. For a number of reasons, this combination has turned out to be less than what we had hoped. One of the biggest problems is that the Microsoft Report Viewer is not a WPF control. We've had other problems as well. Our app consists of at least 5 tabs and each tab has at least 4-5 charts on it. All the charts update on their own timed schedules (like every 15-30 minutes). For the next version I'd like to explore other .NET charting tools for WPF. Performance is absolutely critical. As is resource usage. The tool must support WPF and as many chart types as possible. Can anyone recommend (or not recommend) charting tools they have experience with? We own Telerik and I've dabbled with their charting control. At the 30K foot level, it seems quite nice.

• Loading a SWF dynamically causes previously loaded SWFs to misbehave

  - by Aaron

  I have run into a very strange problem with Flash and Flex. It appears that under certain circumstances, movie clips from a SWF loaded at runtime (using Loader) cannot be instantiated if another SWF has been loaded in the mean time. Here is the complete code for a program that reproduces the error. It is compiled using mxmlc, via Ensemble Tofino: package { import flash.display.*; import flash.events.*; import flash.net.*; import flash.system.*; public class DynamicLoading extends Sprite { private var testAppDomain:ApplicationDomain; public function DynamicLoading() { var request:URLRequest = new URLRequest("http://localhost/content/test.swf"); var loader:Loader = new Loader(); loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onTestLoadComplete); loader.load(request); } private function onTestLoadComplete(e:Event):void { var loaderInfo:LoaderInfo = LoaderInfo(e.target); testAppDomain = loaderInfo.applicationDomain; // To get the error, uncomment these lines... //var request:URLRequest = new URLRequest("http://localhost/content/tiny.swf"); //var loader:Loader = new Loader(); //loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onTinyLoadComplete); //loader.load(request); // ...and comment this one: onTinyLoadComplete(); } private function onTinyLoadComplete(e:Event = null):void { var spriteClass:Class = Class(testAppDomain.getDefinition("TopSymbol")); var sprite:Sprite = Sprite(new spriteClass()); sprite.x = sprite.y = 200; addChild(sprite); } } } With the second loading operation commented out as shown above, the code works. However, if the second loading operation is uncommented and onTinyLoadComplete runs after the second SWF is loaded, the line containing new spriteClass() fails with the following exception: TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::MovieClip@2dc8ba1 to SubSymbol. at flash.display::Sprite/constructChildren() at flash.display::Sprite() at flash.display::MovieClip() at TopSymbol() at DynamicLoading/onTinyLoadComplete()[C:\Users\...\TestFlash\DynamicLoading.as:38] test.swf and tiny.swf were created in Flash CS4. test.swf contains two symbols, both exported for ActionScript, one called TopSymbol and one called SubSymbol. SubSymbol contains a simple graphic (a scribble) and TopSymbol contains a single instance of SubSymbol. tiny.swf contains nothing; it is the result of publishing a new, empty ActionScript 3 project. If I modify test.swf so that SubSymbol is not exported for ActionScript, the error goes away, but in our real project we need the ability to dynamically load sprite classes that contain other, exported sprite classes as children. Any ideas as to what is causing this, or how to fix it?

• LoaderContext and ApplicationDomain changes with Adobe AIR ?

  - by Tyn

  Hello, I'm currently experimenting with loading external SWF files from both an standard AS3 application, and an AIR application. It seems that the AIR application doesn't act the same way a standard SWF run by the Flash Player does. According to the documentation, the applicationDomain property of LoaderContext is usable in an AIR application too, but it just seems to be not working. I have the following code : package { import flash.display.Loader; import flash.display.LoaderInfo; import flash.display.Sprite; import flash.events.Event; import flash.net.URLRequest; import flash.system.ApplicationDomain; import flash.system.LoaderContext; public class Invoker extends Sprite { private var _ldr : Loader; public function Invoker() { _ldr = new Loader(); _ldr.contentLoaderInfo.addEventListener(Event.COMPLETE, onChildOneComplete); var ldrC : LoaderContext = new LoaderContext(false, new ApplicationDomain(ApplicationDomain.currentDomain) ); _ldr.load(new URLRequest("otherSwf.swf"), ldrC); } private function onChildOneComplete(e : Event) : void { var c1ad : ApplicationDomain = (e.target as LoaderInfo).applicationDomain; var inad : ApplicationDomain = ApplicationDomain.currentDomain; trace("Child One parentDomain : " + c1ad.parentDomain); trace("Invoker parentDomain : " + inad.parentDomain); trace("Child One has Invoker : " + c1ad.hasDefinition("Invoker")); trace("Invoker has Invoker : " + inad.hasDefinition("Invoker")); } } } Compiling this code as an SWF file and launching it with the Flash Player does this output, which seems right : Child One parentDomain : [object ApplicationDomain] Invoker parentDomain : null Child One has Invoker : true Invoker has Invoker : true But the same code as an AIR application does a different output : Child One parentDomain : null Invoker parentDomain : null Child One has Invoker : false Invoker has Invoker : true According to the documentation, the first output (using a SWF with Flash Player, and not an AIR application) is the right one. Also, playing around with this snippet and changing the application domain to others possible configurations (like new ApplicationDomain(null), or ApplicationDomain.currentDomain) does exaclty what the documentation says with the SWF, but does not change the output of the AIR application. Any clue why AIR is simply ignoring the application domain passed to the loader context ? Any documentation about this particular issue ? Thank you very much.

• Is it illegal to rewrite every line of an open source project in a slightly different way, and use it in a closed source project?

  - by optician

  There is some code which is GPL or LGPL that I am considering using for an iPhone project. If I took that code (javascript) and rewrote it in a different language for use on the iPhone would that be a legal issue? In theory the process that has happened is that I have gone through each line of the project, learnt what it is doing, and then re implemented the ideas in a new language. To me it seems this is like learning how to implement something, but then re-implementing it separate from the original licence. Therefore you have only copied the algorithm, which arguably you could have learnt from somewhere else other than the original project. Does the licence cover the specific implementation or the algorithm as well?
