  • The best way to structure/design game code

    - by Edward
    My question is quite broad and related to the 2D game code design/architecture/structure. Usually the main game consists of the main loop where you update & render your world states. However, it's recommended for many purposes to separate rendering from the game-logic and so on. I am kinda confused about the whole situation. Many game engines/libs/sdks don't follow separation schema. They propagate a way where you define some scenes/stages and they contain some objects and the scene/stage controls the user input and so on. For example, in cocos2d(-x) and libgdx (stage2d) the games are usually done the way that the update logic happens at the same time/place as rendering. Also, the propagated way is to have a structure where an object knows how to draw itself - which is not a separation of updating & rendering. The same with Flash based games, they are usually done the way when an object (class) contains a swf or a texture and some data and holds some update logic itself, or updated from main Scene. And again this object already knows how to draw itself via "addChild". Also, some people recommend to use MVC pattern, which will require to completely obey the structure of those engines/libs/sdks. Maybe I am overthinking everything, but I am totally confused. I would be grateful if somebody could point me to a correct direction with the game code structures. What is your way of doing things in libgdx/cocos2d/flash?

  • How to use batch rendering with an entity component system?

    - by Kiril
    I have an entity component system and a 2D rendering engine. Because I have a lot of repeating sprites (the entities are non-animated, the background is tile based) I would really like to use batch rendering to reduce calls to the drawing routine. What would be the best way to integrate this with an engtity system? I thought about creating and populating the sprite batche every frame update, but that will probably be very slow. A better way would be to add a reference to an entity's quad to the sprite batch at initialization, but that would mean that the entity factory has to be aware of the Rendering System or that the sprite batch has to be a component of some Cache entity. One case violates encapsulation pretty heavily, while the other forces a non-game object entity in the entity system, which I am not sure I like a lot. As for engine, I am using Love2D (Love2D website) and FEZ ( FEZ website) as entity system(so everything is in Lua). I am more interested in a generic pattern of how to properly implement that rather than a language/library specific solution. Thanks in advance!

  • What is the correlation between programming language and experience/skills of their users?

    - by Petr Pudlák
    I'm sure there is such a correlation, because experience and skill leads good programmers to picking languages that are better for them, in which they're more productive, and working in a language forms how programmers think and influences their methods and skills. Is there any research or some statistical data of this phenomenon? Perhaps this is not a purely academic question. For example, if someone is starting a new project, it could be worth considering a language (among other criteria of course) for which there is a higher chance of finding or attracting experienced programmers. Update: Please don't fixate on the last paragraph. It's not my intention to choose a language based on this criterion, and I know there are other far more important ones. My interested is mostly academic. It comes from the (subjective) observation and I wonder if someone has researched it a bit. Also, I'm talking about a correlation, not about a rule. Sure there are both great and terrible programmers in every language. Just that in general it seems to me there is a correlation.

  • hardware leasing vs purchase

    - by musoNic80
    I'm wanting to get a new laptop and desktop. I'm self-employed and so both bits of kit are primarily for business use. I've been looking into leasing both computers as an alternative to purchasing outright. Does anyone have any experience of this? I'm UK based and have found a company called hardsoft which seem to offer a good service. I'm particularly attracted by the upgrade after 18 months option and the fact that the machines are under warranty for the lift of the lease. I'd be really grateful for general thoughts, especially if there are any UK users or hardsoft clients.

  • Blur gets displaced compared to original image

    - by user1294203
    I have implemented a SSAO and I'm using a blur step to smooth it out. The problem is that the blurred texture is slightly displaced compared to the original. I'm blurring using a 4x4 kernel since that was my noise kernel in SSAO. The following is the blurring shader: float result = 0.0; for(int i = 0; i < 4; i++){ for(int j = 0; j < 4; j++){ vec2 offset = vec2(TEXEL_SIZE.x * i, TEXEL_SIZE.y * j); result += texture(aoSampler, TexCoord + offset).r; } } out_AO = vec4(vec3(0.0), result * 0.0625); Where TEXEL_SIZE is one over my window resolution. I was thinking that this is was an error based on how OpenGL counts the Texel center, so I tried displacing the texture coordinate I was using by 0.5 * TEXEL_SIZE, but there was still a slight displacement. The texture input to my blur shader, has wrap parameters: glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP); When I tell the blur shader to just output the the value of the pixel, the result is not displaced, so it must have something to do with how neighboring pixels are sampled. Any thoughts?

  • Observable Adapter

    - by Roman Schindlauer
    .NET 4.0 introduced a pair of interfaces, IObservable<T> and IObserver<T>, supporting subscriptions to and notifications for push-based sequences. In combination with Reactive Extensions (Rx), these interfaces provide a convenient and uniform way of describing event sources and sinks in .NET. The StreamInsight CTP refresh in November 2009 included an Observable adapter supporting “reactive” event inputs and outputs.   While we continue to believe it enables an important programming model, the Observable adapter was not included in the final (RTM) release of Microsoft StreamInsight 1.0. The release takes a dependency on .NET 3.5 but for timing reasons could not take a dependency on .NET 4.0. Shipping a separate copy of the observable interfaces in StreamInsight – as we did in the CTP refresh – was not a viable option in the RTM release.   Within the next months, we will be shipping another preview of the Observable adapter that targets .NET 4.0. We look forward to gathering your feedback on the new adapter design! We plan to include the Observable adapter implementation into the product in a future release of Microsoft StreamInsight.

  • How can I calculate a vertex normal for a hard edge?

    - by K.G.
    Here is a picture of a lovely polygon: Circled is a vertex, and numbered are its adjacent faces. I have calculated the normals of those faces as such (not yet normalized, 0-indexed): Vertex 1 normal 0: 0.000000 0.000000 -0.250000 Vertex 1 normal 1: 0.000000 0.000000 -0.250000 Vertex 1 normal 2: -0.250000 0.000000 0.000000 Vertex 1 normal 3: -0.250000 0.000000 0.000000 Vertex 1 normal 4: 0.250000 0.000000 0.000000 What I'm wondering is, how can I determine, taken as given that I want this vertex to represent a hard edge, whether its normal should be the normal of 1/2 or 3/4? My plan after I glanced at the sketch I used to put this together was "Ha! I'll just use whichever two faces have the same normal!" and now I see that there are two sets of two faces for which this is true. Is there a rule I can apply based on the face winding, angle of the adjacent edges, moon phase, coin flip, to consistently choose a normal direction for this box? For the record, all of the other polygons I plan to use will have their normals dictated in Maya, but after encountering this problem, it made me really curious.

  • Activate Your Monitor via Motion Trigger

    - by ETC
    Most people are in the habit of jiggling their mouse or tapping their keyboard when they want to wake their monitor. This clever electronics hack adds a sensor to your computer for motion-based monitor activation. At the DIY and electronics blog Radio Etcetera they tackled an interesting project and shared the build guide. Their local volunteer fire department needed a monitor on for quick information checks but they didn’t need it on all the time and they didn’t want to have to walk over and activate the monitor when they needed it. The solution involved hacking a simple infrared security sensor and wiring it via USB to send a mouse command when motion is detected in the room. Fire fighter walks in, monitor turns on and displays information; fire fighter leaves and the monitor goes back to sleep. Hit up the link below to see additional photos, schematics, and the complete build guide.

  • A Virtual Dilemma

    - by antony.reynolds
    Solving a Gotcha with VirtualBox Guest Additions I was just building a new virtual machine based off an existing image that didn’t have the Virtual Box Guest Additions enabled.  The guest additions allow tight integration between the guest OS and the host environment, providing seemless mouse transfer and the ability to take advantage of full video screen size.  The guest additions need to be linked with the kernel which requires the kernel-devel package to be installed.  After installing this package and then trying to add the guest additions it failed, suggesting that I might not have the kernel-devel package that I had installed.  After a little though I finally realized what had happened.  When I grabbed the kernel-devel package I hadn’t checked the version of my kernel.  The kernel-devel I downloaded didn’t match the revision of the kernel I was running!  Hence my problems.  I upgraded the kernel to the same revision as my kernel-devel package and rebooted.  I had installed dkms so I was pleased to see that my VBox Additions successfully built and the mouse and screen now worked as expected. So now you know my embarrassing story for the day :-)

  • How to query a DHCP server to get the local DNS serves

    - by Dan Berlyoung
    I have a ClarkConnect (CentOS based) box running as my home router on a RR connection. I had the DNS servers set up to use Google's DNS server. I want to change them back to the local DNS servers but I can't find an obvious/easy way to get those address short of a)reconfiguring the router's network to DHCP them (would rather not interrupt everyone) or b)calling their T/S (kill me now!).

  • How to query a DHCP server to get the local DNS serves

    - by Dan Berlyoung
    I have a ClarkConnect (CentOS based) box running as my home router on a RR connection. I had the DNS servers set up to use Google's DNS server. I want to change them back to the local DNS servers but I can't find an obvious/easy way to get those address short of a)reconfiguring the router's network to DHCP them (would rather not interrupt everyone) or b)calling their T/S (kill me now!). Is there a command line tool/command I can use to query the DHCP server on the external NIC to see what DNS servers it would set me up with w/o munging my existing setup?

  • Duplicate content appearing for multi lingual sites

    - by Rocky Singh
    I have a site which has a default url say "http://www.blahblah.com/" (which is default in english language). In my site there is support for multi languages. I am having few links at my home page say "English" "French" "Spanish" etc. and on clicking these links user is redirected to these links: http://www.blahblah.com/en-us/ (English) http://www.blahblah.com/fr-ca/ (French) http://www.blahblah.com/spanish-culture/ (Spanish) and based on culture in the url I am showing the content accordingly to end users in their desired language. Now, this was how my site is. The issue I am getting is with SEO. I noticed Google is considering (I checked via Google web masters) my site pages as duplicate like: 1. http://www.blahblah.com/documents/ and http://www.blahblah.com/en-us/documents/ 2. http://www.blahblah.com/news/ and http://www.blahblah.com/en-us/news and similarly all the pages are considered as a duplicate content in Google webmasters tools. I am worried of this, since I think my site is getting penalized in ranking because of this. Could you drop some idea how to overcome this situation?

  • Do you tend to write your own name or your company name in your code?

    - by Connell Watkins
    I've been working on various projects at home and at work, and over the years I've developed two main APIs that I use in almost all AJAX based websites. I've compiled both of these into DLLs and called the namespaces Connell.Database and Connell.Json. My boss recently saw these namespaces in a software documentation for a project for the company and said I shouldn't be using my own name in the code. (But it's my code!) One thing to bear in mind is that we're not a software company. We're an IT support company, and I'm the only full-time software developer here, so there's not really any procedures on how we should write software in the company. Another thing to bear in mind is that I do intend on one day releasing these DLLs as open-source projects. How do other developers group their namespaces within their company? Does anyone use the same class libraries in personal and in work projects? Also does this work the other way round? If I write a class library entirely at work, who owns that code? If I've seen the library through from start to finish, designed it and programmed it. Can I use that for another project at home? Thanks, Update I've spoken to my boss about this issue and he agrees that they're my objects and he's fine for me to open-source them. Before this conversation I started changing the objects anyway, which was actually quite productive and the code now suits this specific project more-so than it did previously. But thank you to everyone involved for a very interesting debate. I hope all this text isn't wasted and someone learns from it. I certainly did. Cheers,

  • WordPress is now nicely supported on SQL Server (and SQL Azure for that matter)

    - by Eric Nelson
    WordPress is enormously popular for blogs and full websites thanks to an awesome eco system which has built up around it, the simplicity (relatively) of getting it up and running plus the flexibility to “bend it” in all sorts of directions. When I say bend, check out the following which are all WordPress sites My “back up blog” http://iupdateable.wordpress.com/  My groups “odd site” :) http://ubelly.com My favourite “cheap games” site http://www.frugalgaming.co.uk/  WordPress users typically run their sites on Linux and MySQL, although PHP (the language in which WordPress is written) can be happily run on Windows. Both fine technologies in their own right, but for me (and probably a fair few others) I would love to use WordPress but with the technologies I know best (aka Windows, IIS and SQL Server). However, that has proven to be actually rather tricky in practice to get working – until now. Earlier last month OmniTI released a patch for WordPress which provides SQL Server and SQL Azure support.  In parallel with that some fine folks inside Microsoft have also created http://wordpress.visitmix.com which contains information about running WordPress on the Microsoft platform with a particular focus on SQL Server and SQL Azure.  Top stuff! To run WordPress with SQL Server: Download and Install the WordPress on SQL Server Distro/Patch And then you will quite likely need to migrate: Check out how to Migrate to Windows and SQL Server by Zach Owens who is moving his blog to Windows and SQL Server Enjoy Related Links Running PHP on IIS on Windows http://php.iis.net/  If PHP is not your thing, then the following Blog engines are .NET based BlogEngine http://www.dotnetblogengine.net/ DasBlog http://www.dasblog.info/ Subtext http://subtextproject.com/ (which happens to power http://geekswithblogs.net where my main blog is http://geekswithblogs.net/iupdateable)

  • Changes to the LINQ-to-StreamInsight Dialect

    - by Roman Schindlauer
    In previous versions of StreamInsight (1.0 through 2.0), CepStream<> represents temporal streams of many varieties: Streams with ‘open’ inputs (e.g., those defined and composed over CepStream<T>.Create(string streamName) Streams with ‘partially bound’ inputs (e.g., those defined and composed over CepStream<T>.Create(Type adapterFactory, …)) Streams with fully bound inputs (e.g., those defined and composed over To*Stream – sequences or DQC) The stream may be embedded (where Server.Create is used) The stream may be remote (where Server.Connect is used) When adding support for new programming primitives in StreamInsight 2.1, we faced a choice: Add a fourth variety (use CepStream<> to represent streams that are bound the new programming model constructs), or introduce a separate type that represents temporal streams in the new user model. We opted for the latter. Introducing a new type has the effect of reducing the number of (confusing) runtime failures due to inappropriate uses of CepStream<> instances in the incorrect context. The new types are: IStreamable<>, which logically represents a temporal stream. IQStreamable<> : IStreamable<>, which represents a queryable temporal stream. Its relationship to IStreamable<> is analogous to the relationship of IQueryable<> to IEnumerable<>. The developer can compose temporal queries over remote stream sources using this type. The syntax of temporal queries composed over IQStreamable<> is mostly consistent with the syntax of our existing CepStream<>-based LINQ provider. However, we have taken the opportunity to refine certain aspects of the language surface. Differences are outlined below. Because 2.1 introduces new types to represent temporal queries, the changes outlined in this post do no impact existing StreamInsight applications using the existing types! SelectMany StreamInsight does not support the SelectMany operator in its usual form (which is analogous to SQL’s “CROSS APPLY” operator): static IEnumerable<R> SelectMany<T, R>(this IEnumerable<T> source, Func<T, IEnumerable<R>> collectionSelector) It instead uses SelectMany as a convenient syntactic representation of an inner join. The parameter to the selector function is thus unavailable. Because the parameter isn’t supported, its type in StreamInsight 1.0 – 2.0 wasn’t carefully scrutinized. Unfortunately, the type chosen for the parameter is nonsensical to LINQ programmers: static CepStream<R> SelectMany<T, R>(this CepStream<T> source, Expression<Func<CepStream<T>, CepStream<R>>> streamSelector) Using Unit as the type for the parameter accurately reflects the StreamInsight’s capabilities: static IQStreamable<R> SelectMany<T, R>(this IQStreamable<T> source, Expression<Func<Unit, IQStreamable<R>>> streamSelector) For queries that succeed – that is, queries that do not reference the stream selector parameter – there is no difference between the code written for the two overloads: from x in xs from y in ys select f(x, y) Top-K The Take operator used in StreamInsight causes confusion for LINQ programmers because it is applied to the (unbounded) stream rather than the (bounded) window, suggesting that the query as a whole will return k rows: (from win in xs.SnapshotWindow() from x in win orderby x.A select x.B).Take(k) The use of SelectMany is also unfortunate in this context because it implies the availability of the window parameter within the remainder of the comprehension. The following compiles but fails at runtime: (from win in xs.SnapshotWindow() from x in win orderby x.A select win).Take(k) The Take operator in 2.1 is applied to the window rather than the stream: Before After (from win in xs.SnapshotWindow() from x in win orderby x.A select x.B).Take(k) from win in xs.SnapshotWindow() from b in     (from x in win     orderby x.A     select x.B).Take(k) select b Multicast We are introducing an explicit multicast operator in order to preserve expression identity, which is important given the semantics about moving code to and from StreamInsight. This also better matches existing LINQ dialects, such as Reactive. This pattern enables expressing multicasting in two ways: Implicit Explicit var ys = from x in xs          where x.A > 1          select x; var zs = from y1 in ys          from y2 in ys.ShiftEventTime(_ => TimeSpan.FromSeconds(1))          select y1 + y2; var ys = from x in xs          where x.A > 1          select x; var zs = ys.Multicast(ys1 =>     from y1 in ys1     from y2 in ys1.ShiftEventTime(_ => TimeSpan.FromSeconds(1))     select y1 + y2; Notice the product translates an expression using implicit multicast into an expression using the explicit multicast operator. The user does not see this translation. Default window policies Only default window policies are supported in the new surface. Other policies can be simulated by using AlterEventLifetime. Before After xs.SnapshotWindow(     WindowInputPolicy.ClipToWindow,     SnapshotWindowInputPolicy.Clip) xs.SnapshotWindow() xs.TumblingWindow(     TimeSpan.FromSeconds(1),     HoppingWindowOutputPolicy.PointAlignToWindowEnd) xs.TumblingWindow(     TimeSpan.FromSeconds(1)) xs.TumblingWindow(     TimeSpan.FromSeconds(1),     HoppingWindowOutputPolicy.ClipToWindowEnd) Not supported … LeftAntiJoin Representation of LASJ as a correlated sub-query in the LINQ surface is problematic as the StreamInsight engine does not support correlated sub-queries (see discussion of SelectMany). The current syntax requires the introduction of an otherwise unsupported ‘IsEmpty()’ operator. As a result, the pattern is not discoverable and implies capabilities not present in the server. The direct representation of LASJ is used instead: Before After from x in xs where     (from y in ys     where x.A > y.B     select y).IsEmpty() select x xs.LeftAntiJoin(ys, (x, y) => x.A > y.B) from x in xs where     (from y in ys     where x.A == y.B     select y).IsEmpty() select x xs.LeftAntiJoin(ys, x => x.A, y => y.B) ApplyWithUnion The ApplyWithUnion methods have been deprecated since their signatures are redundant given the standard SelectMany overloads: Before After xs.GroupBy(x => x.A).ApplyWithUnion(gs => from win in gs.SnapshotWindow() select win.Count()) xs.GroupBy(x => x.A).SelectMany(     gs =>     from win in gs.SnapshotWindow()     select win.Count()) xs.GroupBy(x => x.A).ApplyWithUnion(gs => from win in gs.SnapshotWindow() select win.Count(), r => new { r.Key, Count = r.Payload }) from x in xs group x by x.A into gs from win in gs.SnapshotWindow() select new { gs.Key, Count = win.Count() } Alternate UDO syntax The representation of UDOs in the StreamInsight LINQ dialect confuses cardinalities. Based on the semantics of user-defined operators in StreamInsight, one would expect to construct queries in the following form: from win in xs.SnapshotWindow() from y in MyUdo(win) select y Instead, the UDO proxy method is referenced within a projection, and the (many) results returned by the user code are automatically flattened into a stream: from win in xs.SnapshotWindow() select MyUdo(win) The “many-or-one” confusion is exemplified by the following example that compiles but fails at runtime: from win in xs.SnapshotWindow() select MyUdo(win) + win.Count() The above query must fail because the UDO is in fact returning many values per window while the count aggregate is returning one. Original syntax New alternate syntax from win in xs.SnapshotWindow() select win.UdoProxy(1) from win in xs.SnapshotWindow() from y in win.UserDefinedOperator(() => new Udo(1)) select y -or- from win in xs.SnapshotWindow() from y in win.UdoMacro(1) select y Notice that this formulation also sidesteps the dynamic type pitfalls of the existing “proxy method” approach to UDOs, in which the type of the UDO implementation (TInput, TOuput) and the type of its constructor arguments (TConfig) need to align in a precise and non-obvious way with the argument and return types for the corresponding proxy method. UDSO syntax UDSO currently leverages the DataContractSerializer to clone initial state for logical instances of the user operator. Initial state will instead be described by an expression in the new LINQ surface. Before After xs.Scan(new Udso()) xs.Scan(() => new Udso()) Name changes ShiftEventTime => AlterEventStartTime: The alter event lifetime overload taking a new start time value has been renamed. CountByStartTimeWindow => CountWindow

  • How to determine where on a path my object will be at a given point in time?

    - by Dave
    I have map and an obj that is meant to move from start to end in X amount of time. The movements are all straight lines, as curves are beyond my ability at the moment. So I am trying to get the object to move from these points, but along the way there are way points which keep it on a given path. The speed of the object is determined by how long it will take to get from start to end (based on X). This is what i have so far: //get_now() returns seconds since epoch var timepassed = get_now() - myObj[id].start; //seconds since epoch for departure var timeleft = myObj[id].end - get_now(); //seconds since epoch for arrival var journey_time = 60; //this means 60 minutes total journey time var array = [[650,250]]; //way points along the straight paths if(step == 0 || step =< array.length){ var destinationx = array[step][0]; var destinationy = array[step][1]; }else if( step == array.length){ var destinationx = 250; var destinationy = 100; } else { var destinationx = myObj[id].startx; var destinationy = myObj[id].starty; } step++; When the user logs in at any given time, the object needs to be drawn in the correct place of the path, almost as if its been travelling along the path whilst the user has not been at the PC with the available information i have above. How do I do this? Note: The camera angle in the game is a birds eye view so its a straight forward X:Y rather than isometric angles.

  • Long term plan of attack to learn math?

    - by zhenka
    I am a web-developer with a desire to expand my skill-set to mathematics relevant to programming. As 2nd career, I am stuck in college doing some of the requirements while working. I was hoping the my education will teach me the needed skills to apply math, however I am quickly finding it to be too much easily-testable breadth-based approach very inefficient for the time invested. For example in my calculus 2 class, the only remotely useful mind expanding experience I had was volumes and areas under the curve. The rest was just monotonous glorified algebra, which while comes easy to me, could be done by software like wolfram alpha within seconds. This is not my idea of learning math. So here I am a frustrated student looking for a way to improve my understanding of math in a way that focuses on application, understanding and maximally removed needless tedium. However I cannot find a good long term study strategy with this approach in mind. So for those of like mind, how would you go about learning the necessary math without worrying too much about stuff a computer can do much better?

  • Google Chrome not rendering webpages correctly

    - by sumit_gt
    I am facing some serious web page rendering issues with Chrome. It is more prominent during javascript based animations and stuff on websites like youtube. I have tried removing chrome using (sudo apt-get purge google-chrome-stable) and then reinstalling it. But the problems still persist. The same webpages work correctly on firefox on ubuntu and chrome on windows. The problem only shows up when I use chrome on ubuntu. I think the issue has started after I updated to the latest version of Chrome. I have used Chrome previously on this machine without any problems. I have attached a image that demonstrates the issue.

  • Small-scale database options for .NET

    - by raney
    I have a .NET 4.0/WPF based application I've developed and maintain for my company that acts as a friendly GUI central-point-of-information, combining information pulled from a couple of SQL databases, as well as CSV exports from a few other applications. I would like to build out my own database to support the entirety of the information that the application accesses, so that I could have a service running on my server that would read in necessary remote SQL info and file exports, to provide the user's application with a single database to connect to, as well as to remove all of the file handling currently involved in the program (copying new CSV resources from network location, reading them into memory each launch.) I have complete control and flexibility here as long as the user's experience isn't affected, and this is as much a learning experience as it is tidying up. Caveat being, I don't have much in the way of a budget. Right now I recognize my options to be: SQL Express - I'm comfortable with the server setup, I like ADO.NET and LINQ to SQL. I feel that I have the least to learn here, but it would let me focus on SQL in a familiar environment. Perhaps in conjunction with Entity Framework? MongoDB - I don't know a whole lot about, but I've heard the name enough to make me curious. Brief research seems friendly enough, and there is .NET support. I like working with open source projects. My questions are: What's popular and extensible right now? I'm not far from starting to job-hunt, and I'd like this project to be relevant going forward. What am I missing? Pros, cons? Other options? What plays well with .NET? What are the things I should be considering, the questions I should be asking, when making a decision like this? Thanks for your time.

  • Recovering a lost website with no backup?

    - by Jeff Atwood
    Unfortunately, our hosting provider experienced 100% data loss, so I've lost all content for two hosted blog websites: http://blog.stackoverflow.com http://www.codinghorror.com (Yes, yes, I absolutely should have done complete offsite backups. Unfortunately, all my backups were on the server itself. So save the lecture; you're 100% absolutely right, but that doesn't help me at the moment. Let's stay focused on the question here!) I am beginning the slow, painful process of recovering the website from web crawler caches. There are a few automated tools for recovering a website from internet web spider (Yahoo, Bing, Google, etc.) caches, like Warrick, but I had some bad results using this: My IP address was quickly banned from Google for using it I get lots of 500 and 503 errors and "waiting 5 minutes…" Ultimately, I can recover the text content faster by hand I've had much better luck by using a list of all blog posts, clicking through to the Google cache and saving each individual file as HTML. While there are a lot of blog posts, there aren't that many, and I figure I deserve some self-flagellation for not having a better backup strategy. Anyway, the important thing is that I've had good luck getting the blog post text this way, and I am definitely able to get the text of the web pages out of the Internet caches. Based on what I've done so far, I am confident I can recover all the lost blog post text and comments. However, the images that go with each blog post are proving…more difficult. Any general tips for recovering website pages from Internet caches, and in particular, places to recover archived images from website pages? (And, again, please, no backup lectures. You're totally, completely, utterly right! But being right isn't solving my immediate problem… Unless you have a time machine…)
