• Invalid Html Response and JS Errors when you open your Application in Visual Studio 2013

  - by imran_ku07

   I was working on an application which uses Telerik controls. The application was working fine for a while. Suddenly, the application stopped working. I mean lot of my application pages becoming very very ugly. I found JavaScript errors on every Browser's console. When I check the page view-source, the generated HTML was messy and invalid. This was only happening with my local machine. If someone else on my network accesses my application pages, he will get the correct HTML and no JavaScript errors. My mind was blowing because the same page was generating invalid HTML(and JavaScript errors) when I access the page using a local browser but generate correct HTML(and no JavaScript errors) when someone else access my application page remotely. Then I realized that I the only change I made last was opening my application in Visual Studio 2013 RTM which I installed few days ago. I closed the Visual Studio 2013, everything work like a charm. Then I became100% sure that this is only happening due to new Visual Studio 2013 feature called Browser Link. I just open the application again and add this in web.config. Everything become fine Happy coding :)   <add key="vs:EnableBrowserLink" value="false" />

• Optimal sprite size for rotations

  - by Panda Pajama

  I am making a sprite based game, and I have a bunch of images that I get in a ridiculously large resolution and I scale them to the desired sprite size (for example 64x64 pixels) before converting them to a game resource, so when draw my sprite inside the game, I don't have to scale it. However, if I rotate this small sprite inside the game (engine agnostically), some destination pixels will get interpolated, and the sprite will look smudged. This is of course dependent on the rotation angle as well as the interpolation algorithm, but regardless, there is not enough data to correctly sample a specific destination pixel. So there are two solutions I can think of. The first is to use the original huge image, rotate it to the desired angles, and then downscale all the reaulting variations, and put them in an atlas, which has the advantage of being quite simple to implement, but naively consumes twice as much sprite space for each rotation (each rotation must be inscribed in a circle whose diameter is the diagonal of the original sprite's rectangle, whose area is twice of that original rectangle, supposing square sprites). It also has the disadvantage of only having a predefined set of rotations available, which may be okay or not depending on the game. So the other choice would be to store a larger image, and rotate and downscale while rendering, which leads to my question. What is the optimal size for this sprite? Optimal meaning that a larger image will have no effect in the resulting image. This is definitely dependent on the image size, the amount of desired rotations without data loss down to 1/256, which is the minimum representable color difference. I am looking for a theoretical general answer to this problem, because trying a bunch of sizes may be okay, but is far from optimal.

• how to create a mirror of minimum size to install Ubuntu

  - by Registered User

  I need to create an http url at my laptop to have a Ubuntu installation begin within my laptop on a Xen environment. This is how the final thing will look like http://bderzhavets.wordpress.com/2008/10/28/install-ubuntu-intrepid-server-pv-domu-at-xen-33-port-via-httpgetco-centos-52-dom0/ the host and client are both going to be my laptop, I Google d and came across apt-mirror and some other packages. I do not want to archive entire 15 GB Ubuntu repositories on my machine. It is not possible to use a CD,ISO,loop mounted disk (reason mentioned below). I have tried using netboot image on local machine which failed because if you are attempting to create a virtual machine on a hardware which does not support VT virt-manager installer necessarily needs a URL of this sort http://archive.ubuntu.com/ubuntu/dists/hardy/main/installer-i386/current/images/netboot/ any other option to create guest OS is simply grayed out. The unfortunate part is my Ethernet connections do not work when I boot with Xen-4.0 and a pv-ops Dom0 kernel from Jeremy's tree.Which is where I have to do this work.So I have to create a URL structure which is similar to Ubuntu mirrors.So how can I do this in bare minimum so that at least the console boots and once the console comes I can do some work.

• How to organize a larger project with several sub-projects and their dependencies?

  - by RoToRa

  As a software developer until now, I've mostly worked on projects that were quite "monolithic" with hardly any dependencies on other projects, without building automation (no Make, Ant, Maven, etc.) and kept on a simple version control system (mostly Subversion) with just a few easily managed version branches. Now together with some friends I'm planning a project that is intended to run on multiple platforms (mostly mobile: Android, iOS, Kindle, Windows, etc.), thus written in several languages and on different development platforms. This will lead to many dependencies: All projects sharing the same resources (e.g. images) or projects dependent on each other (e.g. a core Java library project used by the Android and other Java based implementations). So what I need is some basic information on how to answer questions such as: How would the VCS be structured? Would a client-base or a decentralized VCS be better? How to decide building automation system(s) to use? Since this quite an open question I guess for now it would be great if you could point me to any books or web resources that you can recommend for this topic.

• Using SQL tables for storing user created level stats. Is there a better way?

  - by Ivan

  I am developing a racing game in which players can create their own tracks and upload them to a server. Players will be able to compare their best track times to their friends and see world records. I was going to generate a table for each track submitted to store the best times of each player who plays the track. However, I can't predict how many will be uploaded and I imagine too many tables might cause problems, or is this a valid method? I considered saving each player's best times in a string in a single table field like so: level1:00.45;level2:00.43;level3:00.12 If I did this I wouldn't need a separate table for each level (each level could just have a row in a 'WorldRecords' table). However, this just causes another problem because the text would eventually reach the limit for varchar length. I also considered storing the times data in XML files. This would avoid database issues and server disk space can be increased if needed. But I imagine this would be very slow. To update one players best time on one level, I would have to check every node in the file to find their time record to update. Apologies for the wall of text. Any suggestions would be appreciated.

• C++ and system exceptions

  - by Abyx

  Why standard C++ doesn't respect system (foreign or hardware) exceptions? E.g. when null pointer dereference occurs, stack isn't unwound, destructors aren't called, and RAII doesn't work. The common advice is "to use system API". But on certain systems, specifically Win32, this doesn't work. To enable stack unwinding for this C++ code // class Foo; // void bar(const Foo&); bar(Foo(1, 2)); one should generate something like this C code Foo tempFoo; Foo_ctor(&tempFoo); __try { bar(&tempFoo); } __finally { Foo_dtor(&tempFoo); } Foo_dtor(&tempFoo); and it's impossible to implement this as C++ library. Upd: Standard doesn't forbid handling system exceptions. But it seems that popular compilers like g++ doesn't respect system exceptions on any platforms just because standard doesn't require this. The only thing that I want - is to use RAII to make code readable and program reliable. I don't want to put hand-crafted try\finally around every call to unknown code. For example in this reusable code, AbstractA::foo is such unknown code: void func(AbstractA* a, AbstractB* b) { TempFile file; a->foo(b, file); } Maybe one will pass to func such implementation of AbstractA, which every Friday will not check if b is NULL, so access violation will happen, application will terminate and temporary file will not be deleted. How many months uses will suffer because of this issue, until either author of func or author of AbstractA will do something with it? Related: Is `catch(...) { throw; }` a bad practice?

• Update Google Sitemap for Mobile

  - by dimo414

  I have a series of utilities to generate Google sitemaps for my whole site. These files are massive, and slow to build. We want to start telling Google these pages are mobile-crawl-able too, by adding them to mobile sitemaps, but the documentation is unclear if I need to specify physically different files for my mobile URLs than for my normal ones. If this is my current sitemap: <?xml version="1.0" encoding="UTF-8" ?> <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"> <url> <loc>http://mobile.example.com/article100.html</loc> </url> </urlset> Can I simply change it to: <?xml version="1.0" encoding="UTF-8" ?> <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:mobile="http://www.google.com/schemas/sitemap-mobile/1.0"> <url> <loc>http://mobile.example.com/article100.html</loc> <mobile:mobile/> </url> </urlset> Or do I need to create new files with the additional markup, alongside my existing files?

• Procedural content (settlement) generation

  - by instancedName

  I have, lets say, something like a homework or assignment to do. Roughly said I need to write an algorithm (pseudo code is not necessary, just in depth description) of procedure that would generate settlements, environment and a people to populate it with, as part of some larger world generation procedure. The genre of game is not specified, it could be any genre (rpg, strategy, colony simulation etc.) where interacting with large and extensive world is central to the game. Procedure should be called once per settlement. At the time of calling, world generation procedure makes geography, culture and history input available. Output should be map of the village and it's immediate area, and various potential additional information like myths, history, demographic facts etc. Bonus would be quest ant similar stuff, but that not really my focus at the moment. I will leave quality of the output for later when I actually dig little deeper into this topic. I am free to change parameters as long as I have strong explanation for doing so. Setting of the game is undetermined so I am free to use anything that I like the most. Ok, so my actual question is: Can anyone who has some experience in this field of game design recommend me some good literature, or point me in the direction where I should look/reed/study? I'm somewhat experienced game programmer, but I've never been into game design till now so any help will be great. I want to do this assignment as good as I can. As for deadline, it's not strictly set, but lets say I don't want it to take longer then few weeks, one month at worst case.

• SEO - different data with same title and keywords

  - by Junaid Saeed

  here is my scenario i have a website where i redirect my users basing upon the device they were using, lets say a user is visiting from an iPad, i take him directly to the page of iPad wallpapers, the user selects iPad version & i take the user to the gallery of wallpapers where the user can select & download any wallpaper. Every wallpaper is the required resolution, i have my reasons for doing this, now the thing is there are diff. resolution. versions of an image appearing one 5 diff. sections of my website, each having their own view page Now there is only one record in db.table for the image, and basing on the my consistent naming convention of the images, i pick the required image. this means when 5 different pages are generated in 5 categorized sections of the website, due to a shared DB record, the keywords, the titles and every single detail of the 5 pages is same besides the resolution of the image, and the section specific details that the page has and yeah the pages also have different paths like wallpapers.com\ipad-1\cars\Ferrari-dino.html wallpapers.com\ipad-2\cars\Ferrari-dino.html wallpapers.com\ipad-3\cars\Ferrari-dino.html wallpapers.com\ipad-4\cars\Ferrari-dino.html wallpapers.com\ipad-5\cars\Ferrari-dino.html now this is my scenario, How do Search Engines see it and how do they rank it? Is it a Good or Normal or Bad SEO practice? If bad how dangerous it is for my sites SEO? i need your comments on my scenario.

• Is it necessary to add an HP printer to CUPS using the hplip URI?

  - by JPbuntu

  I recently setup a CUPS print server (Ubuntu server 12.04) and I having trouble with performance of a HP Color LaserJet Printer CP3505n. The printer pauses for about a second between printing each page, which is annoying when there is a lot of printing to be done. This doesn't happen when the printer is installed directly to a Windows client. In an attempt to fix this I have setup the printer a couple different ways. I decided not to do a Samba share since this wiki said IPP is preferred. First Method Added to HP LaserJet to CUPS as a Discovered Network Printer, and selected HP Color LaserJet cp3505 hpijs pcl3, 3.12.2 (en) driver. I did not use a hplip URI. Second Method (hplip URI) I thought adding hplip to the mix might improve the performance, so I added the printer like this: Ran hp-setup -m 192.168.2.60, prompted to select driver Selected HP Color LaserJet cp3505 hpijs pcl3, 3.12.2 (en) Used hplip to generate a URI: hp-makeuri 192.168.2.60 Then added the printer to CUPS as a Local Printer: HP Printer (HPLIP), and entered: hp:/net/HP_Color_LaserJet_CP3505?ip=192.168.2.60. Either method I use I am able to share the printer on the network by adding a printer as http://192.168.2.2:631/printers/HP_LASER-TERRAC. Does it make a difference which way the printer is added cups? If so, and I install the printer with the hp URI, can I still change the driver using the CUPS web interface? I have been trying out different drivers to try and improve performance, and the cups interface is the easiest way to change them. Thanks in advance.

• "The protocol 'net.msmq' is not supported."

  - by Randolpho St. John

  OMG, a new lesson! Will wonders never cease? So I ran into an interesting issue setting up a WCF service to consume an MSMQ queue. I won't bother you with the details of how to actually build a WCF/MSMQ service; there are plenty of tutorials on the subject. I want to share with you an interesting error that I ran into and the surprisingly simple fix. The error occurs when attempting to generate a Service Reference or even simply browsing to the WSDL of your WCF/MSMQ service in the form of a YSOD with the following error: "The protocol 'net.msmq' is not supported." After a lot of Googling on the subject turning up plenty of questions with the same error but no answers. So I went digging into some application level config files on a server that already had a WCF/MSMQ service successfully set up by the network admin, and the answer was amazingly simple: If you are hosting an MSMQ/WCF service in IIS, you have to tell IIS to allow net.msmq protocol. It's in the advanced settings for the application or site in which you are hosting the service. .... aaaand, that's it.

• What is causing these visual artifacts on my OpenGL sprites?

  - by Amplify91

  What could be the cause of the defects in my characters sprite? I am using OpenGL ES 2.0. I draw my sprites in a sprite batch that uses UV coordinates from one large texture atlas. If you look around the character' edges, you'll see two noticeable problems: The invisible alpha background is not invisible, but shows a strange static-like background. There are unwanted streaks where the character nears the edge of the frame (but only in some frames of the animation, this happened to be one of them). Any idea what could be causing these? I will provide related code if asked for, but I'll try to avoid just dumping the entire project and expecting someone to look through it all. EDIT: Here's a bit of code: This is how I generate my UV coordinates: private float[] createFrameUV(int frameWidth, int frameHeight, int x, int y){ float[] uv = new float[4]; if(numberOfFrames>1){ float width = (float)frameWidth / (float)mBitmap.getWidth(); float height = (float)frameHeight / (float)mBitmap.getHeight(); float u = (float)x / (float)mBitmap.getWidth(); float v = (float)y / (float)mBitmap.getHeight(); uv[0] = u; uv[1] = v; uv[2] = u + width; uv[3] = v + height; }else{ uv[0] = 0f; uv[1] = 0f; uv[2] = 1f; uv[3] = 1f; } return uv; } These are some OpenGL settings: GLES20.glTexParameterf(GLES20.GL_TEXTURE_2D, GLES20.GL_TEXTURE_MIN_FILTER, GLES20.GL_LINEAR); GLES20.glTexParameterf(GLES20.GL_TEXTURE_2D, GLES20.GL_TEXTURE_MAG_FILTER, GLES20.GL_LINEAR); GLES20.glTexParameterf(GLES20.GL_TEXTURE_2D, GLES20.GL_TEXTURE_WRAP_S, GLES20.GL_CLAMP_TO_EDGE); GLES20.glTexParameterf(GLES20.GL_TEXTURE_2D, GLES20.GL_TEXTURE_WRAP_T, GLES20.GL_CLAMP_TO_EDGE);

• High resolution graphical representation of the Earth's surface

  - by Simon

  I've got a library, which I inherited, which presents a zoomable representation of the Earth. It's a Mercator projection and is constructed from triangles, the properties of which are stored in binary files. The surface is built up, for any given view port, by drawing these triangles in an overlapping fashion to produce the image. The definition of each triangle is the lat/long of the vertices. It looks OK at low values of zoom but looks progressively more ragged as the user zooms in. The view ports are primarily referenced though a rectangle of lat/long co-ordinates. I'd like to replace it with a better quality approach. The problem is, I don't know where to begin researching the options as I am not familiar either with the projections needed nor the graphics techniques used to render them. For example, I imagine that I could acquire high resolution images, say Mercator projections although I'm open to anything, break them into tiles and somehow wrap them onto a graphical representation of a sphere. I'm not asking for "how do I", more where should I begin to understand what might be involved and the techniques I will need to learn. I am most grateful for any "Earth rendering 101" pointers folks might have.

• Managing products on a an ecommerce site [closed]

  - by John

  I've had a site that sells widgets for many years. I do not inventory my widgets, but the cost of adding them to the site and makings sure the site is current is becoming cost prohibitive. Here are the facts: I sell a single class of widget. I have about 50,000 widgets on my site. I have about 100 vendors that create and dropship the products when they get an order from me via email. Each vendor carries from 50 to 5000 types of widgets. Vendors all have websites with images and descriptions of their products. Each widget is produced in limited supply and usually sell out in 1-5 years. Prices of the widget often go up, sometimes more than 50% before they sell out. My vendors aren't very tech sophisticated. They have websites with their products, but most can't supply an api or database dump. Their websites usually display retail prices to the public, but I login or refer to a price list (usually excel) for wholesale prices. As it stands now, I hire local people to add and describe each widget to our website. It usually takes a person 4 minutes to add a widget to the site. This doesn't include moving to a new vendor. I feel like the upload/edit process is as good as it can get via a form/website. The problem is that it is getting very expensive to upload and keep the widget inventory current. I often get orders for something after it's sold out from the vendor or the price is wrong. This seems like it would be a problem in many industries. Can anyone suggest the cheapest way to upload inventory and ensure prices are current from my vendors? I'm assuming it will involve outsourcing, but I would like ideas on how to setup the compensation model.

• Bundling in visual studio 2012 for web optimization

  - by Jalpesh P. Vadgama

  I have been writing a series of posts about Visual Studio 2012 features. This series describes what are the new features in the Visual Studio 2012. This post will also be part of Visual Studio 2012 feature series. As we know now days web applications or site are providing more and more features and due to that we have include lots of JavaScript and CSS files in our web application.So once we load site then we will have all the JavaScript  js files and CSS files loaded in the browsers and If you have lots of JavaScript files then its consumes lots of time when browser request them. Following images show the same situation over there.   Here you can see total 25 files loaded into the system and it's almost more than 1MB of total size. As we need to have our web application of site very responsive and need to have high performance application/site, this will be a performance bottleneck to our site. In situation like this, the bundling feature of Visual Studio 2012 and ASP.NET 4.5 comes very handy. With the help of this feature we do optimization there and we can increase performance of our application. To enable this feature in Visual Studio 2012 we just made debug=”false” in web.config of our application like following. Now once you enable this feature and run this application in the browser to see your traffic it will have less items like following. As you can see in the above image there are only 8 items. So after enabling bundling it will automatically convert all js and css files into the one request. Isn’t that cool feature? This feature will surely going to have great impact on performance. Hope you like it. Stay tuned for more.. Till then happy programming!!

• ADF Faces Skin Editor - How to Work with It

  - by Shay Shmeltzer

  The ODTUG Kscop11 conference was a great success with lots of sessions about FMW running in a special track. I did several sessions and labs in the conference, and I thought it might be a good idea to at least give you a taste of what you might have missed. So here is most of what I demoed in my ADF Faces Skinning session (not all though - that session was 60 minutes long, and while everyone did end up going out of the building in the middle because of a fire drill for about 5 minutes, there was other things covered in the session as well). In the demo here you'll see how to generate new images and default color scheme, how to identify a component class with Firebug, how to skin a component, how to identify the global selector of a property, how to change fonts and how to change strings. By the way, for more on ADF Skinning you should also listen to the ADF Insider seminar that Frank Nimphius recorded on skinning, it will give you better understanding of the overall skinning process. P.S. in the demo I add an entry to the web.xml file which prevent ADF Faces from compressing the HTML that is generated. The entry is for org.apache.myfaces.trinidad.DISABLE_CONTENT_COMPRESSION  and I set it to true. This is very useful when you work on creating the skin, but don't forget to un-set it before you go production.

• Is there an alternative to SDL 1.3 for a C++ game that should run on iOS and Android?

  - by futlib

  I've used SDL for many desktop games, always as the cross-platform glue for: Creating a window Processing input Rendering images Rendering fonts Playing sounds/music It has never disappointed me at those tasks. But when it comes to graphics, I prefer to work with the OpenGL API directly, even though all of our games are 2D. In the project I'm currently working on, I've made sure to only use the API subset supported by both OpenGL 1.3 and OpenGL 1.0, so making the thing run on Android should be easy, I thought. Turns out there is no official Android or iOS port of SDL yet. However, there's one in SDL 1.3, which is still in development. SDL 1.3 doesn't seem very appealing to me for three reasons: It's been in development for at least 4 years, and I have no idea when it will be done, not to mention stable. It's not ported to as many platforms as SDL 1.2. From what I've seen, it uses OpenGL for drawing, so I suppose the community will move away from directly using OpenGL. So I'm wondering if I should use a different library for our current project - it doesn't matter much if I need to port my existing code from SDL 1.2 to SDL 1.3 or to some other library. We're planning to release on Windows, Mac OS X, Linux, iOS and Android, so good support for these platforms is essential. Is there anything stable that does what I want?

• Is a "model" branch a common practice?

  - by dukeofgaming

  I just thought it could be a good thing to have a dedicated version control branch for all database schema changes and I wanted to know if anyone else is doing the same and what have the results been. Say that you are working with: Schema model/documentation (some file where you model the database visually to generate the schema source, say MySQL Workbench, with a .mwb file, which is binary) Schema source (a .sql file) Schema-based code generation The normal way we were working was with feature branches, so we would do changes to the model files (the database specific ones), and then have to regenerate points 2 and 3, dealing with the possible conflicts (or even code rewriting). Now say that your workflow goes the same way as the previous item numbering. With a model branch you wouldn't have to reconcile the schema model with binaries in other feature branches, or have to regenerate schema source and regenerate code (which might have human code on top of it). It makes so much sense to me it feels weird not having seen this earlier as a common practice. Edit: I'm counting on branch merges to be the assertions for the model matching the code. I use a DVCS, so I don't fear long-lived branches or scary-looking merges. I'm also doing feature branching.

• Bullet pattern isn't behaving as expected

  - by Fibericon

  I have a boss that's supposed to continuously shoot five streams of bullets, each at a different angle. It starts off just fine, but doesn't seem to want to use its entire array of bullets. No matter how large I set the length of bulletList, the boss simply stops shooting after a couple of seconds, then pick up again shortly. Here's what I'm using to generate the pattern: Vector3 direction = new Vector3(0.5f, -1, 0); for (int r = 0; r < boss.gun.bulletList.Length; r++) { if (!boss.gun.bulletList[r].isActive) { boss.gun.bulletList[r].direction = direction; boss.gun.bulletList[r].speed = boss.gun.BulletSpeedAdjustment; boss.gun.bulletList[r].position = boss.position; boss.gun.bulletList[r].isActive = true; break; } } direction = new Vector3(-0.5f, -1, 0); //Repeat with four similar for loops, to place a bullet in each direction It doesn't seem to matter if the bulletList length is 1000 or 100000. What could be the issue here?

• Should components have sub-components in a component-based system like Artemis?

  - by Daniel Ingraham

  I am designing a game using Artemis, although this is more of philosophical question about component-based design in general. Let's say I have non-primitive data which applies to a given component (a Component "animal" may have qualities such as "teeth" or "diet"). There are three ways to approach this in data-driven design, as I see it: 1) Generate classes for these qualities using "traditional" OOP. I imagine this has negative implications for performance, as systems then must be made aware of these qualities in order to process them. It also seems counter to the overall philosophy of data-driven design. 2) Include these qualities as sub-components. This seems off, in that we are now confusing the role of components with that of entities. Moreover out of the box Artemis isn't capable of mapping these subcomponents onto their parent components. 3) Add "teeth", "diet", etc. as components to the overall entity alongside "animal". While this feels odd hierarchically, it may simply be a peculiarity of component-based systems. I suspect 3 is the correct way to think about things, but I was curious about other ideas.

• 9 Gigapixel Photo Captures 84 Million Stars

  - by Jason Fitzpatrick

  The European Southern Observatory has released an absolutely enormous picture of the center of the Milky Way captured by their VISTA telescope–the image is 9 gigapixels and captures over 84 million stars. From the press release: The large mirror, wide field of view and very sensitive infrared detectors of ESO’s 4.1-metre Visible and Infrared Survey Telescope for Astronomy (VISTA) make it by far the best tool for this job. The team of astronomers is using data from the VISTA Variables in the Via Lactea programme (VVV), one of six public surveys carried out with VISTA. The data have been used to create a monumental 108 200 by 81 500 pixel colour image containing nearly nine billion pixels. This is one of the biggest astronomical images ever produced. The team has now used these data to compile the largest catalogue of the central concentration of stars in the Milky Way ever created. Want to check out all 9 billion glorious pixels in their uncompressed state? Be prepared to wait a bit, the uncompressed image is available for download but it weighs in at a massive 24.6GB. 84 Million Stars and Counting [via Wired] How Hackers Can Disguise Malicious Programs With Fake File Extensions Can Dust Actually Damage My Computer?

• how to create java zip archives with a max file size limit [closed]

  - by Marci Casvan

  I need to write an algorithm in java (for an android app) to read a folder containing more folders and each of those containing images and audio files so the structure is this: mainDir/subfolders/myFile1.jpg It must be in java, something like perl script is not an option. It would preferably be for the compressed archive in order to squeeze as many files as possible before mailing the zip. Just a normal zip (no jar). My problem is that I need to limit the size of the archive to 16mb and at runtime, create as many archives as needed to contain all my files from my main mainDir folder. I tried several examples from the net, I read the java documentation, but I can't manage to understand and put it all together the way I need it. Has someone done this before or has a link or an example for me? I resolved the reading of the files with a recursive method but I can't write the logic for the zip creation I'm open for suggestions or better, a working example. EDIT: FileNotFoundException (no such file or directory) this was my initial post at Stack Overflow. I've got an answer to it, but I can't set the size of the ZipEntry and the logic doesn't work and also when extracting the my files from the zip I get the compression method not supported error.

• How can I avoid a 302 for Fetch as Bot?

  - by CookieMonster

  I originally posted this on Stackoverflow, but I believe here is a better place to ask. My web application is very similar to notepad.cc which redirects to a randomly generated URL upon access, e.g. http://myapp.com/roTr94h4Gd. (Please note that notepad.cc is not my site.) Probably because of this redirect feature, when I do "fetch as Google" or "fetch as Bingbot", I get a 302 and no html content. Not even a <html></html> tag. HTTP/1.1 302 Moved Temporarily Server: nginx/1.4.1 Date: Tue, 01 Oct 2013 04:37:37 GMT Content-Type: text/html Transfer-Encoding: chunked Connection: keep-alive X-Powered-By: PHP/5.4.17-1~dotdeb.1 Set-Cookie: PHPSESSID=vp99q5e5t5810e3bnnnvi6sfo2; expires=Thu, 03-Oct-2013 04:37:37 GMT; path=/ Expires: Thu, 19 Nov 1981 08:52:00 GMT Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0 Pragma: no-cache Location: /roTr94h4Gd How should I avoid 302 in this case? I suppose I could modify my site to prevent the redirect, but it is a necessary feature of my web app to generate a random URL on each access. I added <meta name="fragment" content="!"> tag into my index page and set it to return a static snapshot of my page when the flag is set. But this still returns a 302. I also added a header to return 200 before redirecting, but this had no effect, either. Could someone tell me a good suggestion to solve this problem?
