• Can't get directory listing on my Apache to work.

  - by joon

  Hi, I'm having trouble enabling the directory listing on apache. I did it a few weeks ago but had to reinstall cause my Wubi ran out of space, and now I can't get it to work and it's driving me crazy. I have a folder /home/joon/Dropbox/Projects/apache, which I want to set as the root for my apache. Here's the first lines of the 'default' file in the sites-available folder: <VirtualHost *:8888> ServerAdmin webmaster@localhost DocumentRoot /home/joon/Dropbox/Projects/apache <Directory /home/joon/Dropbox/Projects/apache> Options +Indexes FollowSymLinks AllowOverride None The rest is unchanged. Ports.conf is set to Listen 8888. I thought the +Indexes should do it, but I must have overlooked something. I get a 403, forbidden. "You don't have permission to access / on this server." If I input the url of an image, http://127.0.0.1:8888/joon/bin/1chart.png, it displays, but no directory listing. Please help.

• Point an external domain to a shared hosting website

  - by dailgez004

  I bought a domain from a seller (GoDaddy), and wish to point it at a shared hosting website (ASmallOrange). Googling tells me it's fairly straightforward: Step 1: On the external domain's DNS, configure two NS records for the two nameservers of the hosting service. Step 2: Wait 2-48 hours. I'm puzzled because it can't be that simple. I've told the DNS where to look, but since it's shared hosting, the hosting service needs to know what site to point the domain to. And indeed, after I've performed the above steps, visiting the domain leads me to a generic message from the shared hosting service. Okay, so I have to configure the DNS on the hosting service, right? The service I use (ASmallOrange) uses cPanel. What I tried is to set up a Parked Domain for the externally bought domain; when I go into the Advanced DNS Zone Editor, sure enough, the DNS for the external domain shows up as something I can configure. Yet, visiting the externally registered domain still points me to the generic shared server page. I'm convinced I'm doing something wrong. Could someone debug my thought process? Or perhaps offer alternate solutions? Right now, I'm considering trying to set up a CNAME record on the external domain to point to the domain I registered through the shared host -- but I have a vague impression that this is bad practice.

• FP for simulation and modelling

  - by heaptobesquare

  I'm about to start a simulation/modelling project. I already know that OOP is used for this kind of projects. However, studying Haskell made me consider using the FP paradigm for modelling a system of components. Let me elaborate: Let's say I have a component of type A, characterised by a set of data (a parameter like temperature or pressure,a PDE and some boundary conditions,etc.) and a component of type B, characterised by a different set of data(different or same parameter, different PDE and boundary conditions). Let's also assume that the functions/methods that are going to be applied on each component are the same (a Galerkin method for example). If I were to use an OOP approach, I would create two objects that would encapsulate each type's data, the methods for solving the PDE(inheritance would be used here for code reuse) and the solution to the PDE. On the other hand, if I were to use an FP approach, each component would be broken down to data parts and the functions that would act upon the data in order to get the solution for the PDE. This approach seems simpler to me assuming that linear operations on data would be trivial and that the parameters are constant. What if the parameters are not constant(for example, temperature increases suddenly and therefore cannot be immutable)? In OOP, the object's (mutable) state can be used. I know that Haskell has Monads for that. To conclude, would implementing the FP approach be actually simpler,less time consuming and easier to manage (add a different type of component or new method to solve the pde) compared to the OOP one? I come from a C++/Fortran background, plus I'm not a professional programmer, so correct me on anything that I've got wrong.

• How do I partition my Hard drive to install Kubuntu?

  - by Xdflames

  I am a complete newbie to partitioning and I would like some guidance here. Can anyone explain what exactly I should be doing here? I am installing Kubuntu 12.04 on a currently Windows 7 laptop. My current Partitions say this: /dev/sda /dev/sda1 ntfs 104 MB 35 MB /dev/sda2 ntfs 319965 MB 87164 MB Basically, what I want is some guidance on what exactly to do here. All I want is a partition for my OS (Which will be Kubuntu 12.04) and a partition for all of my data. I also want to restart fresh with my hard drive, with only what I mentioned on here. I am installing Kubuntu from a flash drive (I set it up as a bootable device with Universal-USB-Installer-1.9.0.9), as I do not have any blank CDs/DVDs to burn to. What should I name my partitions? What should I set the type as? What size do they need to be? Edit: My hard drive is 320GB. Just looked it up in my BIOS. This computer will mainly be used for internet browsing and overall just messing around with the Linux OS.

• Ubuntu Server 12.04, NAT, Router, DNS. It just doesnt work

  - by Bjørnar Kibsgaard

  I recently inherited some server hardware from work and decided that it could be my main router at home (among other things). Ubuntu 12.04 server installation harware wise goes well and everything is found and working when I boot up. So I begin with setting up eth1 with DHCP. This works fine and it gets a public IP address from my modem and we have a working internet connection. Then I set up my other NIC (eth0) as static (192.168.0.1) and this also works fine. I can access it from other computers in the network. The problems are coming when I am trying to set up a DHCP server with isc-dhcp-server. It seems like it is working and giving the computers IP adresses but after one reboot it stops working. After the reboot eth1 will get a public ip from the modem but it doesnt have internet access. I have to manually run dhcpcd eth1 to get it to work again. As far as I know I havent made any changes to DNS. What am I doing wrong? I have never really had problems with this before. :)

• MVC 3: ActionLink VB.Net

  - by xamlnotes

  Theres not a ton of good samples out there on using MVC with VB, so I am going to post some things that I am doing on a project. Lets look at links. I am converting a asp classic app to mvc.  One page has an anchor tag which I modified to look like so to point to a controller action: <A style=color:red; HREF='Detail/" & currentItem.IdNumber & "'>" & currentItem.IdNumber & "</A> This resolves out to what looks like the right URL and in fact the detail action is fired. The actions signature looks like so: Function Detail(ByVal IdNumber As String) As ActionResult But, IdNumber would always be blank, it was never set to the id passed in the url.  Hmm. So, I tried the following by using the ActionLink method of the html helper: Html.ActionLink(currentLead.LeadNumber, "Detail", New With {.IdNumber = currentItem.IdNumber })  Viola! That worked fine and the Detail method parameter was set just like it should be. Very interesting.

• 2D Camera Acceleration/Lag

  - by Cyral

  I have a nice camera set up for my 2D xna game. Im wondering how I should make the camera have 'acceleration' or 'lag' so it smoothly follows the player, instead of 'exactly' like mine does now. Im thinking somehow I need to Lerp the values when I set CameraPosition. Heres my code private void ScrollCamera(Viewport viewport) { float ViewMargin = .35f; float marginWidth = viewport.Width * ViewMargin; float marginLeft = cameraPosition.X + marginWidth; float marginRight = cameraPosition.X + viewport.Width - marginWidth; float TopMargin = .3f; float BottomMargin = .1f; float marginTop = cameraPosition.Y + viewport.Height * TopMargin; float marginBottom = cameraPosition.Y + viewport.Height - viewport.Height * BottomMargin; Vector2 CameraMovement; Vector2 maxCameraPosition; CameraMovement.X = 0.0f; if (Player.Position.X < marginLeft) CameraMovement.X = Player.Position.X - marginLeft; else if (Player.Position.X > marginRight) CameraMovement.X = Player.Position.X - marginRight; maxCameraPosition.X = 16 * Width - viewport.Width; cameraPosition.X = MathHelper.Clamp(cameraPosition.X + CameraMovement.X, 0.0f, maxCameraPosition.X); CameraMovement.Y = 0.0f; if (Player.Position.Y < marginTop) //above the top margin CameraMovement.Y = Player.Position.Y - marginTop; else if (Player.Position.Y > marginBottom) //below the bottom margin CameraMovement.Y = Player.Position.Y - marginBottom; maxCameraPosition.Y = 16 * Height - viewport.Height; cameraPosition.Y = MathHelper.Clamp(cameraPosition.Y + CameraMovement.Y, 0.0f, maxCameraPosition.Y); }

• Opportunities in Cloud Computing

  - by Paul Sorensen

  A recent article from CIO Journal indicates that there is an extreme labor shortage (in certain technology areas) that is is leading to upward pressure on wages for IT Workers. This represents a great opportunity for those with certain skill-sets, among which include Java (Oracle certification is mentioned specifically). The article points out that a key driver of the labor shortage is the expansion of cloud computing. Cloud computing is set up to make life extremely simple for end-users, but the model pushes the complexity to back-end systems which are sophisticated, enterprise-level computing stacks (Oracle has an extensive set of cloud computing solutions). These complex systems require very highly-skilled IT professionals (the best-of-the-best) to successfully develop, implement, administer and maintain them. What this mean for you is that there is opportunity for those who have the appropriate skills at the appropriate levels. If you want to be a part of this opportunity you should do a self-assessment of your own skill-sets and experience. Based upon your results you can decide where it would be most appropriate to spend your time and resources for the highest return on your investment. By expanding and sharpening your skills and by gaining greater experience you will be better prepared to take advantage of career opportunities (like this) that come along periodically. As you evaluate your needs remember that Oracle University has a tremendous selection of high-quality eduction offerings (including training and certification) that can you help move your career forward. Thanks and best of luck!

• Cannot establish ssh connection to computer on local network

  - by ovangle

  I've just (re)installed ubuntu 11.10 on my main pc, and the connection times out every time I try to ssh connect to my laptop (over the local network) to retrieve the files I backed up there. The connection times out every time I try to connect. I can establish a connection in the other direction without issue. Here's the verbose output I get when I try to connect: ovangle@ruby-EP43-DS3:~$ ssh -v [email protected] OpenSSH_5.8p1 Debian-7ubuntu1, OpenSSL 1.0.0e 6 Sep 2011 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug2: ssh_connect: needpriv 0 debug1: Connecting to 10.1.1.4 [10.1.1.4] port 22. debug1: connect to address 10.1.1.4 port 22: Connection timed out ssh: connect to host 10.1.1.4 port 22: Connection timed out ssh is installed on both machines, and I've tried deleting '~/.ssh/known_hosts' on both machines, still nada. I've changed the sshd logging on the laptop to VERBOSE and restarted the daemon (because I wasn't getting any relevant syslog entries otherwise), and this is the log for the most recent connection attempt. EDIT: posted wrong logs last time. They just showed that there was a connection received, they weren't actually the sshd logs (which were in auth.log as I recently discovered). Unfortunately, that log is filling up with extremely weird error messages and it gives me no information about the connection.

• Is the Entity Component System architecture object oriented by definition?

  - by tieTYT

  Is the Entity Component System architecture object oriented, by definition? It seems more procedural or functional to me. My opinion is that it doesn't prevent you from implementing it in an OO language, but it would not be idiomatic to do so in a staunchly OO way. It seems like ECS separates data (E & C) from behavior (S). As evidence: The idea is to have no game methods embedded in the entity. And: The component consists of a minimal set of data needed for a specific purpose Systems are single purpose functions that take a set of entities which have a specific component I think this is not object oriented because a big part of being object oriented is combining your data and behavior together. As evidence: In contrast, the object-oriented approach encourages the programmer to place data where it is not directly accessible by the rest of the program. Instead, the data is accessed by calling specially written functions, commonly called methods, which are bundled in with the data. ECS, on the other hand, seems to be all about separating your data from your behavior.

• NFS users getting a laggy GUI expierence

  - by elzilrac

  I am setting up a system (ubuntu 12.04) that uses ldap, pam, and autofs to load users and their home folders from a remote server. One of the options for login is sitting down at the machine and starting a GUI session. Programs such as chormium (browser) that preform many read/write operations in the ~/.cache and ~/.config files are slowing down the GUI experience as well as putting strain of the NFS server that is causing other users to have problems. Ubuntu had the handy-dandy XDG_CONFIG_HOME and XDG_CACHE_HOME variables that can be set to change the default location of .cache and .config from the home folder to somewhere else. There are several places to set them, but most of them are not optimal. /etc/environment pros: will work across all shells cons: cannot use variables like $USER so that you can't make users have different new locations for .cache and .config. Every users' new location would be the same directory. /etc/bash.bashrc pros: $USER works, so you can place them in different folders cons: only gets run for bash compatible shells ~/.pam_environment pros: works regardless of shell cons: cannot use system variables (like $USER), has it's own syntax, and has to be created for every user

• Cannot access windows share

  - by Wrigley

  I have an accounting program specifically tailored to the IT industry, its called Fincon (exe based). It basically works on a client to server directory base system. the server is currently running on a windows 7 machine with a NTFS partition. I have installed Wine. Have the shared Windows directory mounted with what I assume is the correct command for such being (mount -tsmbfs //servername/sharedir /mnt/fincon -0 usename=username,password=password). I can see the shared dir although it does take a bit long to access it on the Ubuntu machine via the mapped directory but instant via normal network browsing. I have also set up the mapped directory to my D: drive in Wine and have pointed the fincon.ini to read server field from D: directly. Here's my issue, it seems that for some odd reason I cant write to the mapped directory from Ubuntu, yet I can with my Windows machines, the permissions are set correct on the Windows 7 share and I really dunno what I'm missing. I'm quite a Linux noob just switched yesterday. Thanks guys for any help in this would be quite appreciated. As I'm pulling out my hair here and really want to migrate my work PCs to a Linux OS as it just gives less issues than Windows does ever.

• Basic Puppet installation with Solaris 11.2 beta

  - by user13366125

  At the recent announcement we talked a lot about the Puppet integration. But how do you set it up? I want to show this in this blog entry. However this example i'm using is even useful in practice. Due to the extremely low overhead of zones i'm frequently seeing really large numbers of zones on a single system. Changing /etc/hosts or changing an SMF service property on 3 systems is not that hard. Doing it on a system with 500 zones is ... let say it diplomatic ... a job you give to someone you want to punish. Puppet can help in this case making of managing the configuration and to ease the distribution. You describe the changes you want to make in a file or set of file called manifest in the Puppet world and then roll them out to your servers, no matter if they are virtual or physical. A warning at first: Puppet is a really,really vast topic. This article is really basic and it doesn't goes more than just even toe's deep into the possibilities and capabilities of Puppet. It doesn't try to explain Puppet ... just how you get it up and running and do basic tests. There are many good books on Puppet. Please read one of them, and the concepts and the example will get much clearer immediately. (more)

• Game engine lib and editor

  - by luke

  I would like to know the best way/best practice to handle the following situation. Suppose the project you are working on is split in two sub-projects: game engine lib editor gui. Now, you have a method bool Method( const MethodParams &params ) that will be called during game-level initialization. So it is a method belonging to the game engine lib. Now, the parameters of this method, passed as a reference the structure MethodParams can be decided via the editor, in the level design phase. Suppose the structure is the following: enum Enum1 { E1_VAL1, E1_VAL2, }; enum Enum2 { E2_VAL1, E2_VAL2, E2_VAL3, }; struct MethodParams { float value; Enum1 e1; Enum2 e2; // some other member } The editor should present a dialog that will let the user set the MethodParams struct. A text control for the field value. Furthermore, the editor needs to let the user set the fields e1 and e2 using, for example, two combo boxes (a combo box is a window control that has a list of choices). Obviously, every enum should be mapped to a string, so the user can make an informed selection (i have used E1_VAL1 etc.., but normally the enum would be more meaningful). One could even want to map every enum to a string more informative (E1_VAL1 to "Image union algorithm", E1_VAL2 to "Image intersection algorithm" and so on...). The editor will include all the relevant game egine lib files (.h etc...), but this mapping is not automatic and i am confused on how to handle it in a way that, if in future i add E1_VAL3 and E1_VAL4, the code change will be minimal.

• More NASM with GVim

  - by MarkPearl

  Today I am bashing around with nasm again… some useful things I found… Set the current working directory of gvim to the current file path I have found setting the current working directory of gvim to the file location is very useful, especially if you are wanting to use commands in gvim to run your compiled code. It can be done by typing in the following in the command mode in gvim… cd %:p:h Once you have set it, you can use the ! to run commands you would normally run in the dos shell.. e.g. !dir Compiling code to make an executable There are three thing you need to specify to compile a basic file in name, they are… The output file format The output file name The source file name An example of this would be the following (where you have a file called temp.asm which is the source file) nasm –f bin temp.asm –o temp.com Output file format The –f specifies the output file format (in this case a binary file). To get a list of the available output file formats you can type nasm –hf (for my installation bin is the default, in which case I can omit it) Output file name This is just the name you want the compiled file to be called. For windows machines I specify .com as my default format.

• Are specific types still necessary?

  - by MKO

  One thing that occurred to me the other day, are specific types still necessary or a legacy that is holding us back. What I mean is: do we really need short, int, long, bigint etc etc. I understand the reasoning, variables/objects are kept in memory, memory needs to be allocated and therefore we need to know how big a variable can be. But really, shouldn't a modern programming language be able to handle "adaptive types", ie, if something is only ever allocated in the shortint range it uses fewer bytes, and if something is suddenly allocated a very big number the memory is allocated accordinly for that particular instance. Float, real and double's are a bit trickier since the type depends on what precision you need. Strings should however be able to take upp less memory in many instances (in .Net) where mostly ascii is used buth strings always take up double the memory because of unicode encoding. One argument for specific types might be that it's part of the specification, ie for example a variable should not be able to be bigger than a certain value so we set it to shortint. But why not have type constraints instead? It would be much more flexible and powerful to be able to set permissible ranges and values on variables (and properties). I realize the immense problem in revamping the type architecture since it's so tightly integrated with underlying hardware and things like serialization might become tricky indeed. But from a programming perspective it should be great no?

• View the Time & Date in Chrome When Hiding Your Taskbar

  - by Asian Angel

  Do you prefer keeping your Taskbar hidden but still need to keep watch on what time it is? Now you can keep track of the time without the Taskbar using the Date Today extension for Google Chrome. A Look at Date Today with Different Themes This extension does one thing and does it well…it provides you with an “active icon” clock that will let you view the time and date in two fashions. The first is by hovering your mouse over the “Toolbar Clock Button”… And the second is by clicking on the “Toolbar Clock Button” to view an enlarged version. Here you can see the extension in use with five different themes to get an idea of how it might look with the theme that you are currently using. It does stand out very nicely with brighter or darker colored themes. Conclusion While this extension is obviously not for everyone it will make a nice (and useful) addition to Chrome for those who prefer keeping their Taskbar hidden.

• After reboot allocated node gets commissioned again

  - by cloudfan

  i had set up a maas with juju and deployed Openstack into it for testing. During my vacation i shut down all computers. Afterwards i started at first the maas server, then the node where juju was bootstrapped and juju-gui was deployed to. Sadly the node got commissioned again and so all my deployments are gone. I decomissioned the according node from the maas and bootstrapped it again. Afterwards i tested again juju bootstrapping the node, shutting down both nodes and starting them in the same order again. The Juju node gets commisioned again. After bootstrapping everything looked fine in the MAAS GUI (node was set to allocated to root, which was also the case after the restart) and also the JUJU GUI was available and juju status worked fine. Before my vacation i also had some other nodes deployed through juju. They all seem to be still available and have not been commisioned again. Do you have any ideas what might have happened? Is there any issue with a bootstrapped juju node and the commisioning? Any help or hints on what i could check are appreciated! Thank in advance for your help!

• WordPress mod_rewrite redirect specific folders

  As a new user, I'm not allowed to post more than two hyperlinks here. So I have added a space after every http (ignore them and read as full URLs). System: Debian Etch, Apache 2.2 I have a WordPress instance with multiple blogs. I would like to redirect some of the folders based on the year and month, while leaving other folders go to the actual locations. Example: I have archives for a few years, like 2010, 2011 and 2012: http ://mydomain.com/wordpress/myblog/2010/02 http ://mydomain.com/wordpress/myblog/2011/01 http ://mydomain.com/wordpress/myblog/2012/01 I would like to redirect all 2010 and 2011 posts to another blog with the same folder structure: http ://mydomain.com/wordpress/myotherblog/2010/02 http ://mydomain.com/wordpress/myotherblog/2011/01 and so on. I would like to have 2012 and beyond to go to the actual site (http ://mydomain.com/wordpress/myblog/2012/01). I tried mod_rewrite with the following, one rule at a time to test redirection for just one year (and to expand later for other years), and none of them worked! * RewriteEngine is already on since there are some default WordPress rewrites. * RewriteBase is set to http://mydomain.com/wordpress/ . * I put my rule before all the other default WordPress rules are processed. Didn't work solution #1 RedirectMatch 301 /myblog/2010/(.*) /myotherblog/2010/$1 Didn't work solution #2 RewriteRule /myblog/2010/(.*) http ://mydomain.com/myotherblog/2010/$1 [R=301] Didn't work solution #3 RedirectPermanent /myblog/2010/(.*) http ://mydomain.com/myotherblog/2010/$1 I've also tried the above rules with and without a fully qualified URL for the new location. The rewrite log, with log level set to 9, did not provide any useful information. It shows that it looks at the pattern specified against the URL (as mentioned in the rule), but finally what happens is a passthrough to http ://mydomain.com/myblog/ for all URLs or a 500 Internal Server Error. Any ideas on where I could be going wrong or any alternative solutions?

• A tip: Updating Data in SharePoint 2010 using REST API

  - by Sahil Malik

  SharePoint 2010 Training: more information Here is a little tip that will save you hours of head scratching. See there are two ways to update data in SharePoint using REST based API. A PUT request is used to update an entire entity. If no values are specified for fields in the entity, the fields will be set to default values. A MERGE request is used to update only those field values that have changed. Any fields that are not specified by the operation will remain set to their current value.   Now, sit back and think about it. You are going to update the entire entity! Hmm. Which means, you need to a) specify every column value, and b) ensure that the read only values match what was supplied to you. What a pain in the donkey! So 99/100 times, a PUT request will give you a HTTP 500 internal server error occurred, which is just so helpful. Read full article ....

• SharePoint: UI for ordering list items

  - by svdoever

  SharePoint list items have in the the base Item template a field named Order. This field is not shown by default. SharePoint 2007, 2010 and 2013 have a possibility to specify the order in a UI, using the _layouts page: {SiteUrl}/_layouts/Reorder.aspx?List={ListId} In SharePoint 2010 and 2013 it is possible to add a custom action to a list. It is possible to add a custom action to order list items as follows (SharePoint 2010 description): Open SharePoint Designer 2010 Navigate to a list Select Custom Actions > List Item Menu Fill in the dialog box: Open List Settings > Advanced Settings > Content Types, and set Allow management of content types to No  On List Settings select Column Ordering This results in the following UI in the browser: Selecting the custom Order Items action (under List Tools > Items) results in: You can change your custom action in SharePoint designer. On the list screen in the bottom right corner you can find the custom action: We now need to modify the view to include the order by adding the Order field to the view, and sorting on the Order field. Problem is that the Order field is hidden. It is possible to modify the schema of the Order field to set the Hidden attribute to FALSE. If we don’t want to write code to do it and still get the required result it is also possible to modify the view through SharePoint Designer: Modify the code of the view: This results in: Note that if you change the view through the web UI these changes are partly lost. If this is a problem modify the Order field schema for the list.

• Should this code/logic be included in Business Objects class or a separate class?

  - by aspdotnetuser

  I have created a small application which has a three tier architecture and I have business object classes to represent entities such as User, Orders, UserType etc. In these classes I have methods that are executed when the Constuctor method of, for example, User is called. These methods perform calculations and generate details that setup data for attributes that are part of each User object. Here is the structure for the project in Visual Studio: Here is some code from the business object class User.cs: Public Class User { public string Name { get; set; } public int RandomNumber { get; set; } etc public User { Name = GetName(); RandomNumber = GetRandomNumber(); } public string GetName() { .... return name; } public int GetRandomNumber() { ... return randomNumber; } } Should this logic be included in the Business Object classes or should it be included in a Utilities class of some kind? Or in the business rules?

• JDeveloper News &ndash; Did You Know

  - by shay.shmeltzer

  There have been a few issues lately with access to blogs.oracle.com to write new messages – and as a result I’m a little behind on reporting the latest and greatest in JDeveloper. (I’m also unable to approve comments :-( ) But just in case you missed it here are a few note worthy things you should know: ADF Mobile Client went production – this is a solution that let you use ADF to develop on-device applications for mobile devices. You develop once and run on various devices (right now Blackberry and Windows Mobile with other platforms coming soon). For more information check out the ADF Mobile page on OTN. ADF Developer Certification goes production – you can now take the official test and get an official certification that you can include in your resume.Should be a must for any consultant looking to get ADF related gigs. Learn more about the ADF Certification Exam. ADF Vision Stencils Released – If you are looking for a quick way to draw prototypes of ADF screens you probably can’t get any faster and more accurate results than this. This is a set of Vision components that you can drag over and design a page visually. You can also set properties for components and do other advance things. You do need a license for Visio to use this, but the ADF stencils are free. We’ve been using these internally at Oracle for some time now and we thought the ADF community would enjoy these too. Download the ADF Visio Stencils here (and watch a youtube demo of how they work).
