  • Design pattern for animation sequence in LibGDX

    - by kevinyu
    What design pattern to use for sequence of animation that involve different actor in libGDX. For example I am making a game to choose a wolf from a group of sheeps. The first animation played when the game begin is the wolf enter the field that is filled with two sheeps.Then the wolf disguise as a sheep and goes to the center of the screen. Then the game will shuffle the sheeps. After it finished it will ask the player where is the wolf. The game wait for player input. After that the game will show animation to show the player whether their answer is right or wrong. I am currently using State design pattern. There are four states wolfEnterState,DisguiseState,ShuffleState,UserInputState, and answerAnimationState. I feel that my code is messy. I use addAction with action sequence and action completion(new Runnable()) a lot. I feel that the action sequence is getting long. Is there a better solution for this kind of problem

  • Integrating Twitter Into An ASP.NET Website

    Twitter is a popular social networking web service for writing and sharing short messages. These tidy text messages are referred to as tweets and are limited to 140 characters. Users can leave tweets and follow other users directly from Twitter's website or by using the Twitter API. Twitter's API makes it possible to integrate Twitter with external applications. For example, you can use the Twitter API to display your latest tweets on your blog. A mom and pop online store could integrate Twitter such that a new tweet was added each time a customer completed an order. And ELMAH, a popular open-source error logging library, can be configured to send error notifications to Twitter. Twitter's API is implemented over HTTP using the design principles of Representational State Transfer (REST). In a nutshell, inter-operating with the Twitter API involves a client - your application - sending an XML-formatted message over HTTP to the server - Twitter's website. The server responds with an XML-formatted message that contains status information and data. While you can certainly interface with this API by writing your own code to communicate with the Twitter API over HTTP along with the code that creates and parses the XML payloads exchanged between the client and server, such work is unnecessary since there are many community-created Twitter API libraries for a variety of programming frameworks. This article shows how to integrate Twitter with an ASP.NET website using the Twitterizer library, which is a free, open-source .NET library for working with the Twitter API. Specifically, this article shows how to retrieve your latest tweets and how to post a tweet using Twitterizer. Read on to learn more! Read More >

  • Atheros wireless not working

    - by Chandru1
    I have been struggling hard since i have installed Ubuntu 10.10 but it has been difficult for me to get my wifi working. So here is what i tried. First i checked whether i have the driver using the ifconfig command and it shows the wireless lan driver as wlan0. Next, i tried the command iwlist wlan0 scanning by becoming the root which gave me the output as no scan results. Next, i visited this link https://help.ubuntu.com/community/WifiDocs/Driver/Atheros to see as to what problem my laptop may have. I do own have an ath5k chipset. And as i followed the instructions in the above link in one of the blacklist-ath_pci.conf file had this written in it. For some Atheros 5K RF MACs, the madwifi driver loads buts fails to correctly initialize the hardware, leaving it in a state from which ath5k cannot recover. To prevent this condition, stop madwifi from loading by default. Use Jockey to select one driver or the other. (Ubuntu: #315056, #323830 I am not that good at Linux but i have given it a try. I am desperate to have my wifi working and i would be glad if this community could help. ADDED: If anyone would like to know as to what drivers i am using this is the output. network description: Wireless interface product: AR2413 802.11bg NIC vendor: Atheros Communications Inc. physical id: 3 bus info: pci@0000:0a:03.0 logical name: wlan0 version: 01 serial: 00:19:7d:d3:0c:fd width: 32 bits clock: 33MHz capabilities: pm bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=ath5k driverversion=2.6.35-24-generic firmware=N/A latency=168 link=no maxlatency=28 mingnt=10 multicast=yes wireless=IEEE 802.11bg resources: irq:18 memory:d0000000-d000ffff Some more information and output as to what i have done. lsmod | grep ath ath5k 130083 0 mac80211 231541 1 ath5k ath 8153 1 ath5k cfg80211 144470 3 ath5k,mac80211,ath led_class 2633 1 ath5k

  • After force-installing a 32-bit deb failed, how can I install the 64-bit version?

  • Why does modx-based site start using different domains for some content?

    - by naxa
    situation I have a modx site on a VPS with multiple domain and subdomain names. The modx site should use what I call the 'primary' domain name's 'primary' subdomain, ie www.intendedname.tld . The problem is that as time pass, the site mysteriously starts using another subdomain for links to content like videos, images, and even pages and (internal) links. The other subdomains doesn't serve this content of course. If I clear the modx cache, the original state is restored. However, the problem comes back again later. The VPS has a domain registered and multiple A records pointing to the VPS's IP, as subdomains. There is the 'primary' whan which is intended to be used as the public content server, the other ones are like docs. and test., etc. On top of that, I have dynamic-dns service client installed from no-ip on the machine and a dynamic domain-name bound. It gives a completely different domain name. I originally used it for ssh login and to serve a completely different site. An nginx server is put into good use to do rewrite the different subdomains to the right places. edit The modx templates use Templates use <base href="[[++site_url]]" />. current attempt to fix The current 'solution' to the problem is to also use the rewrite to rewrite everything to the 'primary' domain and subdomain. In the nginx config file for the site, it utilizes (unsurprisingly) the rewrite directive to rewrite the unexpected server_name entries (ie. the other subdomains) in a server block dedicated to this task. So with this, the main site basically works (sort of) but this renders all the other functions (docs) useless. Before this rewrite was set, the 'solution' was to clear the modx cache on a regular basis. The original modx content is not getting corrupted, only the files in cache are. What can I do to find out what actual the problem is and fix it?

  • Problem with WCF-SQL Adapter

    - by Paul Petrov
    When using WCF receive adapter with SQL binding in Polling mode please be aware of the following problem. Problem: At some regular but seemingly random intervals the application stops processing new requests, places a lock on the database and prevent other application from accessing it. Initially it looked like DTC issue, as it was distributed transaction that stalled most of the time. Symptoms: Orchestration instances in Dehydrated state, receive location not picking up new messages, exclusive locks on database tables, errors in DTC trace. Cause: Microsoft has confirmed that there is a bug in the WCF-SQL adapter. In the receive adapter binding configuration there's receiveTimeout property set to 10 minutes by default. If during this period data is not found in the table the adapter would start new thread and allocate more memory without releasing old resources. Thus if there's no new data in the table for a long time a new thread will be created in the host instance every 10 minutes until it reaches threshold (1000) and then there's no threads left for this host instance and it can't start/complete any tasks. Then this host instance won't be able to do anything. If other artifacts are hosted in the instance they will suffer consequences as well. Solution: - Set receiveTimeout to the maximum time 24.20:31:23.6470000. - Place WCF-SQL receive locations in separate host to provide its own thread pool and eliminate impact on other processes - Ensure WCF-SQL dedicated host instances are restarted at interval less or equal to receiveTimeout to flush threads and memory - Monitor performance counters Process/Thread Count/BTSNTSvc{n} for thread count trend and respond to alert if it grows by restarting host instance If you use WCF-SQL Adapter in the Notification mode then make sure to remove sqlAdapterInboundTransactionBehavior otherwise this location will exhibit the same issue. In this case though, setting receiveTimeout doesn't help and new thread will be created at default intervals (10 min) ignoring maximum setting.

  • Cannot FTP without simultaneous SSH connection?

    - by Lucas
    I'm trying to set up an old box as a backup server (running 10.04.4 LTS). I intend to use 3rd party software on my PC to periodically connect to my server via FTP(S) and to mirror certain files. For some reason, all FTP connection attempts fail UNLESS I'm simultaneously connected via SSH. For example, if I use putty to test the connection to port 21, the system hangs and times out. I get: 220 Connected to LeServer USER lucas 331 Please specify the password. PASS [password] <cursor> However, when I'm simultaneously logged in (in another session) everything works: 220 Connected to LeServer USER lucas 331 Please specify the password. PASS [password] 230 Login successful. Basically, this means that my software will never be able to connect on its own, as intended. I know that the correct port is open because it works (sometimes) and nmap gives me: Starting Nmap 5.00 ( http://nmap.org ) at 2012-03-20 16:15 CDT Interesting ports on xx.xxx.xx.x: Not shown: 995 closed ports PORT STATE SERVICE 21/tcp open ftp 22/tcp open ssh 53/tcp open domain 139/tcp open netbios-ssn 445/tcp open microsoft-ds Nmap done: 1 IP address (1 host up) scanned in 0.15 seconds My only hypothesis is that this has something to do with iptables. Maybe it's allowing only established connections? I don't think that's how I set it up, but maybe? Here's my iptables rules for INPUT: lucas@rearden:~$ sudo iptables -L INPUT Chain INPUT (policy DROP) target prot opt source destination fail2ban-ssh tcp -- anywhere anywhere multiport dports ssh ufw-before-logging-input all -- anywhere anywhere ufw-before-input all -- anywhere anywhere ufw-after-input all -- anywhere anywhere ufw-after-logging-input all -- anywhere anywhere ufw-reject-input all -- anywhere anywhere ufw-track-input all -- anywhere anywhere ACCEPT tcp -- anywhere anywhere tcp dpt:ftp I'm using vsftpd.

  • Boot failure after update and system crash 11.10

    - by Alubuntu
    I'm using: Dell XPS M1330 laptop, Ubuntu 11.10 32bits, single boot (only Linux OS), Virtualbox (with Windows XP on virtual machine). System crashed while working with a very heavy image on GIMP (and Virtualbox was on). During the same session, I made an automatic system update, but don't know what was exactly updated. After the crash the system doesn't boot. Always freezes on terminal screen but at different stages, ""Starting CUPS printing spooler/server", "Checking battery state", "mountall: plymouth command failed", etc. Sometimes indicates [failed] in some of the processes and sometimes they're all [ok]. Did a Boot info summary with boot-repair and gave me this report http://paste.ubuntu.com/1050743/ This is not a new install, have been using it for almost 6 months...though since last month it couldn't halt..it started shutting down and stopped at black screen with fan on and on/off light still on (I used to finish the shutdown process by forcing halt with a long-press of the power button). I don't know if these has anything to do with the boot failure. Is there anyway I can solve this issue (the boot failure) or make some sort of system check to find out what is the cause of the problem? I wasn't sure if this was the right place to ask the question, so I also did it at https://answers.launchpad.net/ubuntu/+question/201004

  • How to set TextureFilter to Point to make example Bloom filter work?

    - by Mr Bell
    I have simple app that renders some particles and now I am trying to apply the bloom shader from the xna samplers ( http://create.msdn.com/en-US/education/catalog/sample/bloom ) to it, but I am running into this exception: "XNA Framework HiDef profile requires TextureFilter to be Point when using texture format Vector4." When the BloomComponent tries to end the sprite batch in the DrawFullscreenQuad method: spriteBatch.Begin(0, BlendState.Opaque, SamplerState.PointWrap, null, null, effect); spriteBatch.Draw(texture, new Rectangle(0, 0, width, height), Color.White); spriteBatch.End(); //<------- Exception thrown here It seems to be related to the pixel shaders that I am using to animate the particle. In a nutshell, I have a texture2d in vector4 format that holds particle positions, and another one for velocities. Here is a snippet from that area: GraphicsDevice.SetRenderTarget(tempRenderTarget); animationEffect.CurrentTechnique = animationEffect.Techniques[technique]; spriteBatch.Begin(SpriteSortMode.Immediate, BlendState.Opaque, SamplerState.PointWrap, DepthStencilState.DepthRead, RasterizerState.CullNone, animationEffect); spriteBatch.Draw(randomValues, new Rectangle(0, 0, width, height), Color.White); spriteBatch.End(); What I comment out the code that calls the particle animation pixel shaders the bloom component runs fine. Is there some state that I need to reset to make the bloom work?

  • Sending Emails via Google SMTP - after some time quit working

    - by Chris
    on a website I use PHPMailer to send automated registration emails, etc and also a newsletter-tool (which loops through the emails and sends them one by one). Also, I configured in Gmail under Settings and confirmed @mydomain addresses, so I can send from @mydomain emails without the gmail address being displayed. Furthermore I authorized the website to send mails with this link: https://accounts.google.com/DisplayUnlockCaptcha Now, after 2 month where everything worked perfectly fine, suddenly users started not to receive emails anymore and most recently emails are not even being sent anymore. Also, I received many error messages like this: Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 5.4.1 [email protected]: Recipient address rejected: Access Denied (state 13). When I check at this link: https://toolbox.googleapps.com/apps/checkmx/ It tells 2 none critical errors: Relayhost configuration detected. There SHOULD be a valid SPF record. So, the questions I would have were: does anybody have any hint why it stopped working, what the error messages mean? what to do to fix it? where do I set a SPF record (Cpanel?)? what is a relayhost and how to fix that? It is about 1000-1400 mails a day (gmail's limit is 2000). Also, what can I do wrong when setting up an SPF record? I've heard there are some testing tools for that. Thank you so much already in advance for your help!

  • What would you do to improve the working of a small Development team?

    - by Omar Kooheji
    My company is having a reshuffle and I'm applying for my boss' job as he's moved up the ladder. The new role would give me a chance to move our development team into the 21st century and I'd like to make sure that: I can provide sensible suggestions in the interview to get the job so I can fix the team If I get the job I can actually enact some changes to actually improve the lives of the developers and their output. I want to know what I can suggest to improve the way we work, because I think it's a mess but every time I've suggested a change it's been shot down because any time spend implementing the change would be time that isn't spent developing software. Here is the state of play at the moment: My team consists of 3-4 developers (Mainly Java but I do some .Net work) Each member of the team is usually works on 2-3 projects at a time We are each responsible for the entire life cycle of the project from design to testing. Usually only one person works on a project (Although we have the odd project that will have more than one person working on it.) Projects tend to be bespoke to single customer, or are really heavilly reliant on a particular customer environment. We have 2-3 "Products" which we evolve to meet customer requirements. We use SVN for source control We don't do continuous integration (I'd like to start) We use a really basic bug tracker for internal issue tracking (I'd like to move to an issue/task management system) Any changes that bring a sudden dip in revenue generation will probably be rejected, the company isn't structured for development most of the rest of the technical team's jobs can be broken down to install this piece of hardware, configure that piece of hardware and once a job is done it's done and you never have to look at it again. This mentality has crept into development team because it's part of the company culture.

  • Vehicle: Boat accelerating and turning in Unity

    - by Emilios S.
    I'm trying to make a player-controllable boat in Unity and I'm running into problems with my code. 1) I want to make the boat to accelerate and decelerate steadily instead of simply moving the speed I'm telling it to right away. 2) I want to make the player unable to steer the boat unless it is moving. 3) If possible, I want to simulate the vertical floating of a boat during its movement (it going up and down) My current code (C#) is this: using UnityEngine; using System.Collections; public class VehicleScript : MonoBehaviour { public float speed=10; public float rotationspeed=50; // Use this for initialization // Update is called once per frame void Update () { // Forward movement if(Input.GetKey(KeyCode.I)) speed = transform.Translate (Vector3.left*speed*Time.deltaTime); // Backward movement if(Input.GetKey(KeyCode.K)) transform.Translate (Vector3.right*speed*Time.deltaTime); // Left movement if(Input.GetKey(KeyCode.J)) transform.Rotate (Vector3.down*rotationspeed*Time.deltaTime); // Right movement if(Input.GetKey(KeyCode.L)) transform.Rotate (Vector3.up*rotationspeed*Time.deltaTime); } } In the current state of my code, when I press the specified keys, the boat simply moves 10 units/sec instantly, and also stops instantly. I'm not really sure how to make the things stated above, so any help would be appreciated. Just to clarify, I don't necessarily need the full code to implement those features, I just want to know what functions to use in order to achieve the desired effects. Thank you very much.

  • Project Corndog: Viva el caliente perro!

    - by Matt Christian
    During one of my last semesters in college we were required to take a class call Computer Graphics which tried (quite unsuccessfully) to teach us a combination of mathematics, OpenGL, and 3D rendering techniques.  The class itself was horrible, but one little gem of an idea came out of it.  See, the final project in the class was to team up and create some kind of demo or game using techniques we learned in class.  My friend Paul and I teamed up and developed a top down shooter that, given the stringent timeline, was much less of a game and much more of 3D objects floating around a screen. The idea itself however I found clever and unique and decided it was time to spend some time developing a proper version of our idea.  Project Corndog as it is tentatively named, pits you as a freshly fried corndog who broke free from the shackles of fair food slavery in a quest to escape the state fair you were born in.  Obviously it's quite a serious game with undertones of racial prejudice, immoral practices, and cheap food sold at high prices. The game itself is a top down shooter in the style of 1942 (NES).  As a delicious corndog you will have to fight through numerous enemies including hungry babies, carnies, and the corndog serial-killer himself the corndog eating champion!  Other more engaging and frighteningly realistic enemies await as the only thing between you and freedom. Project Corndog is being developed in Visual Studio 2008 with XNA Game Studio 3.1.  It is currently being hosted on Google code and will be made available as an open source engine in the coming months.

  • Closer Aero-snap in ubuntu

    - by Andrew Redd
    Before I get screamed at for duplicating a question. Ive read windows 7-like snap window maximize and vertical feature and http://www.omgubuntu.co.uk/2009/11/get-aero-snap-in-ubuntu/ There are two problems with this solution that I am trying to get around. It's not sensitive to dragging a window It's not intelligent for Twin-view monitors. The first problem is the more pressing. I have the compiz settings with wmctrl, but this is not sensitive to dragging windows if I have a window with the focus and place my mouse in the panel I get the window maximized, even though I'm not dragging the window. A good solution would be sensitive to the state of the mouse, clicked, right clicked, middle clicked. An ideal solution would be sensitive to dragging a window or not. Second is a minor annoyance to me at least. With the commands as they are listed are equivalent to maximizing the windows since I have a Twinview monitors setup. Is there any way to add these sensitivities to the commands?

  • DDD Model Design and Repository Persistence Performance Considerations

    - by agarhy
    So I have been reading about DDD for some time and trying to figure out the best approach on several issues. I tend to agree that I should design my model in a persistent agnostic manner. And that repositories should load and persist my models in valid states. But are these approaches realistic practically? I mean its normal for a model to hold a reference to a collection of another type. Persisting that model should mean persist the entire collection. Fine. But do I really need to load the entire collection every time I load the model? Probably not. So I can have specialized repositories. Some that load maybe a subset of the object graph via DTOs and others that load the entire object graph. But when do I use which? If I have DTOs, what's stopping client code from directly calling them and completely bypassing the model? I can have mappers and factories to create my models from DTOs maybe? But depending on the design of my models that might not always work. Or it might not allow my models to be created in a valid state. What's the correct approach here?

  • Recommended main loop style

    - by Frootmig-H
    I've just begun attempting an FPS with JMonkeyEngine, but I'm currently stuck as to the best way to implement the main loop - especially with regards to non-instantaneous user actions. By that, I mean things like reloading a weapon. The user starts the action, and it continues for a while with an animation and some sound, and when it completes, game state updates. (I should mention that it's not technically a loop, it's an update method, called as often as possible. Is that different? Me no understand terminology). So, far I've considered : Animation driven Player presses reload Start reload animation If user stars another action, abort animation, start new action. When the animation_complete event is received (JMonkeyEngine provides this), update ammo counters. Event driven Player presses reload Start reload animation Queue up a out-of-thread method to be called at time t + (duration of reload animation) If user starts another action, cancel both animation and queued method. When queued method executes, update ammo. This avoids relying on the animation event (JMonkeyEngine has a particular quirk), but brings in the possibility of thread problems. 'Blocking' (not sure of the correct term) Player presses reload Start reloading animation reloading = true reloadedStartTime = now while (reloading && ((now - reloadingStartTime) < reloadingDuration)) { If user starts another action, break and cancel reloading. } Update ammo counters reloading = false My main concern is that actions can interrupt each other. Reloading can be interrupted by firing, or by dropping or changing weapon, crouching can be interrupted by running, etc. What's the recommended way to handle this? What are the advantages and disadvantages of each method? I'm leaning towards event-driven, even though it requires more care; failing that, blocking.

  • Google earth will not reinstall

    - by chad
    I was trying to perform the the fix found at this link http://www.omgubuntu.co.uk/2012/01/how-to-make-google-earth-look-native-in-ubuntu It requires you to delete certain files from the /opt/google/earth/free folder and then add some new ones that you download. I deleted the files but the links to download the new ones were unusable. I was using gksudo nautilus so trash was disabled meaning I could not restore the files I had deleted. I the tried to go to the Google Earth website and reinstall it. I downloaded the .deb but when I tried to install it it gav me an error message saying "cannot install ia32-libs" I tried installing this via terminal and it gave me an error message saying chad@chad-Lenovo-G570:~$ sudo apt-get install ia32-libs [sudo] password for chad: Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: ia32-libs : Depends: ia32-libs-multiarch E: Unable to correct problems, you have held broken packages. How do I fix this? Now I am stuck without a functioning Google Earth. How can I fix this?

  • Windows Phone 7 Prototype 002: Animated Page Transitions + Writeable Bitmaps

    Motion is a key part of WP7 application development. Without motion, the WP7 UI is just a bunch of text. Not nearly as exciting. To delight users, you can add some transitions between pages.  The sample app includes some storyboards to animate between two pages. Other people have noted that you can just use the transitioning content control form the SIlverlight toolkit. Peter Torr also had a nice animating frame control in his mix demo code (his blog has some other great code samples for WP7 app dev). I took some of those concepts and the code from the TransitioningContentControl to make a new animating frame control. In this prototype, the frame takes a snapshot of the old content and the new content using writeable bitmaps and animates the snapshots and then replaces those with the actual page. The benefit is smoother animation on pages with lots of controls. Otherwise, if you have a large panorama, it might not animate that cleanly.  Like the other solutions based on the TransitioningContentControl, you can centralize all the animations in one place and not have to handle them on each individual page. Peters code also had a nice snippet for choosing the animation based on the navigation direction so you could just have a forward / backward animation and not have to do anything on each page. You could also probably add some more advanced transitions using pixel shaders or make an default no transition state if you wanted to have some specific animation on a page where individual  controls transitioned out differently like some of the WP7 shell apps. Sample Code 100% guaranteed to work on my emulatorDid you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Keeping multiple root directories in a single partition

    - by intuited
    I'm working out a partition scheme for a new install. I'd like to keep the root filesystem fairly small and static, so that I can use LVM snapshots to do backups without having to allocate a ton of space for the snapshot. However, I'd also like to keep the number of total partitions small. Even with LVM, there's inevitably some wasted space and it's still annoying and vaguely dangerous to allocate more. So there seem to be a couple of different options: Have the partition that will contain bulky, variable files, like /srv, /var, and /home, be the root partition, and arrange for the core system state — /etc, /usr, /lib, etc. — to live in a second partition. These files can (I think) be backed up using a different backup scheme, and I don't think LVM snapshots will be necessary for them. The opposite: putting the big variable directories on the second partition, and having the essential system directories live on the root FS. Either of these options require that certain directories be pointers of some variety to subdirectories of a second partition. I'm aware of two different ways to do this: symlinks and bind-mounts. Is one better than the other for this purpose? Is there another option? Do any of the various Ubuntu installation media/strategies support this style of partition layout?

  • Duck checker in Python: does one exist?

    - by elliot42
    Python uses duck-typing, rather than static type checking. But many of the same concerns ultimately apply: does an object have the desired methods and attributes? Do those attributes have valid, in-range values? Whether you're writing constraints in code, or writing test cases, or validating user input, or just debugging, inevitably somewhere you'll need to verify that an object is still in a proper state--that it still "looks like a duck" and "quacks like a duck." In statically typed languages you can simply declare "int x", and anytime you create or mutate x, it will always be a valid int. It seems feasible to decorate a Python object to ensure that it is valid under certain constraints, and that every time that object is mutated it is still valid under those constraints. Ideally there would be a simple declarative syntax to express "hasattr length and length is non-negative" (not in those words. Not unlike Rails validators, but less human-language and more programming-language). You could think of this as ad-hoc interface/type system, or you could think of it as an ever-present object-level unit test. Does such a library exist to declare and validate constraint/duck-checking on Python-objects? Is this an unreasonable tool to want? :) (Thanks!) Contrived example: rectangle = {'length': 5, 'width': 10} # We live in a fictional universe where multiplication is super expensive. # Therefore any time we multiply, we need to cache the results. def area(rect): if 'area' in rect: return rect['area'] rect['area'] = rect['length'] * rect['width'] return rect['area'] print area(rectangle) rectangle['length'] = 15 print area(rectangle) # compare expected vs. actual output! # imagine the same thing with object attributes rather than dictionary keys.

  • Dirt Cheap DSLR Viewfinder Improves Outdoor DSLR LCD Visibility

    - by Jason Fitzpatrick
    If the excitement you felt about having a DSLR capable of shooting video wore off the second you took it outside and realized you needed an expensive add-on viewfinder to use it in sunlight, this cheap DIY viewfinder is for you. The digital video capabilities of new DSLR cameras are amazing and changing the way people interact with movie production.
