'abstract' wood burning.

Not sure if this should be posted here, Outdoors or Square Pegs, but it's art related so I'll ask here. I once saw a how-to video, I am 90% sure is was on this site. but there is a chance it wasn't. I would like help finding it again. From what I remember, the person showing off had: a car battery, a long needle,  plank of wood and some chemical. the process I remember was (but may not be 100% accurate): 1. (s)he painted on a layer of chemical (or acids) on the wood 2. stabbed the needle on the wood 3. connected the battery to the needle 4. turned the battery on. it then made some elegant, fancy patterns, like a bare tree, or a lightning bolt. lots of 'branches' and paths were burned into the wood (without manual intervention. it was 'natral'). like a chemical reaction. if anyone has the name of this technique, or a video/instructable/guide, I would really appreciate a link. Thank! EDIT: solution found: it's called "Fractal Woodburning" (go on youtube for some videos). I should have known, I love fractials! you need: saline wood needles and a high-voltage power source. and patience.

How do you make a 12x1 LED Matrix?

Hi everyone, I'm completely new to this site as well as DIY projects so I would love some help on a uni project I am currently trying to start. My idea is to make an abstract clock which only contains an hour hand only and the clock face itself will rotate to tell the hour. The hand will be made up of a 12x1 LED matrix. Each light is supposed to represent each 12th segment of the clock and will light up when it is past that segment in time. For example, at 3:15, the clock face will have rotated so the hour hand (that always points up) points on the 3 and 3 out of 12 LEDs will be lit. This has to be programmed with an Arduino. Being new to physical computing etc. I am so stuck on how to even begin this project! If anyone has any ideas of how I can begin this please let me know! Or just help me get started by telling me how I can make a simple 12x1 LED matrix to act as the hour hand. I look forward to your replies, many thanks everyone!

When do humans develop abstract reasoning?

This is a great demonstration of abstract reasoning, and the lack thereof in small children. Apparently kids will (almost) always fail this test up to age 4, and almost always pass after age 7. The magic transitional age varies, of course.Parents and siblings, this should give some great hints on how to seem "fair" while still short-changing your child. ;)

Essentially, they're starting to develop abstraction levels for DNA programming, building modular components analogous to those used by mechanical or electrical engineers. Endy speculates that eventually, this will develop into a viable, hackable, source for materials and components that could be used by everyday hackers. I found this incredible, but mostly awesome!

You can help save a rare frog from extinction!

First off, I realize instructables does not want pure advertising on their site through these forms. The voting is optional and I don't want this to be viewed as advertisement. If nothing else, I want to share with you our story in the project, and hopefully you'll see how awesome this is. We are doing something that no high school has ever achieved before, and I think it's more relevant to the site than some re-posting of a blog article. I hope that you take a few minutes and find out what the Frog Project is all about! Want to support the cause of helping endangered species, education, and advancing biotech in schools? Well, take 5 minutes and vote for our school to convince Khols' to give us 1/2 million $$! Unfortunately the contest is over, but we're going to go for a $250,000 grant for a Pepsi contest in November. If you become a fan of our page (noted below) you'll be updated. Check back in November! https://www.facebook.com/pages/The-AAEC-Frog-Project/128763967175416 ======================================================== Not convinced? Well, here's our story: You can help save a rare frog from extinction, and it is free! Kohls the dept. store is donating $500,000 to the 20 schools with the most creative need for the money. Your vote can help our school win this money, and best of all it costs you nothing! We are working on a project to try and save a rare frog from extinction. And we need the cash. At our small high school of 300 students, we are trying to completely sequence the genome of a rare Arizona frog. We hope to accomplish 2 things from this work. 1) We hope to rescue this frog from extinction. 2) We hope to train a new generation of students in modern biotechnology, and rescue the State of Arizona from last place in quality of education in the United States. The Chiricahua Leopard frog is currently listed as a threatened species. We have been working in conjunction with the Phoenix Zoo and Arizona Game and Fish to develop a genetic test that could aid in conservation efforts. We have already spent a year working on the sequence of the mitochondrial chromosome of this frog. Our school actually owns a DNA sequencer. We have made pioneering efforts in the design of genetic tests for this frog. Our students have presented 5 posters on our work at the International Plant and Animal Genome conference (PAG), quite an achievement for a high school. Our project was recently awarded one of only three heritage grants: http://www.gf.state.az.us/w_c/heritage_projects.shtml By the way, the other two Heritage grants were awarded to Arizona State University and Northern Arizona University. What we really wish to do is completely sequence every chromosome in this frog. This is a very ambitious project. Consider that the human genome project completed in 2003, cost $3 billion dollars and took 13 years. Our leopard frog is estimated to contain twice as much DNA as humans! However, we think that with appropriate funding, and new technology that has recently become available we can accomplish this task in 2 years! We wish to construct what are called “DNA libraries”, collections of broken chromosome fragments of known sizes. These can be sequenced quickly using NEXT generation sequencing technology. The Chinese genomic group BGI has agreed to cover the costs of NEXT generation sequencing, and genome assembly for our project (an estimated $1 million) if our school can come up with the remaining funds needed for the construction of the libraries. We need to purchase about $200,000 in new equipment, and extend our existing lab space. With the completed genome sequence, we would like to have a custom “gene chip” manufactured. This chip will have all the DNA of the frog physically printed on it. The chip allows experiments to be carried out without any harm to any frog. This chip could then be used to aid conservation efforts by the Phoenix Zoo and Arizona Game & Fish. It could allow the exact parentage of every Chiricahua frog that is discovered to be known. Eventually this technology will become the backbone of conservation work on all species, but at this early stage it is not possible for Arizona Game & Fish to raise the funds needed to generate a gene chip before it is too late for the frog. Our school hopes to be the first in history to carry out a genome project. We hope this will serve as a guiding light to other schools, and start a grass-roots movement in the conservation and education world. Help us save our frog! Here is the catch. Vote for us on Facebook, and convince all your friends to do the same (forward this message to them), or unfortunately the frog bites it! Everybody can vote up to 5 times for us. In this way YOU can help make the difference not only for this rare species, but if we can succeed you will help pave the way to help many others. https://apps.facebook.com/KohlsCares/school/32741/aaec-paradise-valley Regards, -Mike Dr. Mike Brown Science Dept.

The oldest known astronomical atlas -- ca. 667 CE !

I ran across a preprint today which I find wonderfully impressive. It documents a Chinese astronomical atlas prepared some time between 649-684 CE (AD, for the oldsters) , and covering the complete visible sky of the Northern Hemisphere. Star positions are accurate to within a couple of degrees (with naked eye observations). As the authors write in their abstract, This set of sky maps (12 hour angle maps in quasi-cylindrical projection and a circumpolar map in azimuthal projection), displaying the full sky visible from the Northern hemisphere, is up to now the oldest complete preserved star atlas from any civilisation. It is also the first known pictorial representation of the quasi-totality of the Chinese constellations.

How can I extend my stay in UK?

Hello I hope that you are fine. I need to seek advice in a matter related to my visa/stay extension in UK. I am an international student and have done Masters this year, hence have a tier 4 visa. My visa is going to expire on 3rd of February  next year. There is a good chance that I might stay in UK for a year or two if I get an extension of 2-3 weeks as there is a good chance that I might work for the university from which I graduated. The only hindrance in my way is that it would be until end of January that the job that I am interested in, would be advertised. The description in the job will be well suited to the area of my expertise, so there is a good change that I'll get it. Furthermore I wanted to add that I have been working for the same university for a period of two months as a research assistant, but it was a contract based job and has already been finished. Can I get a tier 2 visa on the basis of that? In addition to that I have a conference paper to be presented in April. the deadline for the submission of abstract is 21/12/12, and I'll submit an abstract before I reach the deadline. I'll receive confirmation that my paper has been included in the conference within one and half month. Will I be able to extend my visa based on my conference paper? I have read on the UK boarder agency website that if you want to appear in a conference then you'll have to apply for a business visa, and it was enlisted that for this visa category you might not have any intentions to work in UK. Can my student visa be extended based on my conference paper and can I apply for visa extension a week or two before that date of my visa expiry? It would be really nice if you could help me out with this mess as my hopes are diminishing as the days pass by. Kind Regards

It's (not) life, Jim ... but not as we know it

From this week's Science magazine online abstracts:Self-Sustained Replication of an RNA EnzymeTracey A. Lincoln and Gerald F. JoyceAn RNA enzyme that catalyzes the RNA-templated joining of RNA was converted to a format whereby two enzymes catalyze each other’s synthesis from a total of four oligonucleotide substrates. These cross-replicating RNA enzymes undergo self-sustained exponential amplification in the absence of proteins or other biological materials. Amplification occurs with a doubling time of about one hour, and can be continued indefinitely. Populations of various cross-replicating enzymes were constructed and allowed to compete for a common pool of substrates, during which recombinant replicators arose and grew to dominate the population. These replicating RNA enzymes can serve as an experimental model of a genetic system. Many such model systems could be constructed, allowing different selective outcomes to be related to the underlying properties of the genetic system.

Jargon ... it's not just for breakfast anymore

Here's the title and abstract of a preprint that was posted to arXiv yesterday. I have no certain idea of what it all mean, and I'm a practicing physicist! I just find the ratio of unintelligible jargon to English really amusing.Monopole and Topological Electron Dynamics in Adiabatic Spintronic and Graphene SystemsAuthors: S. G. Tan, M. B. A. Jalil, Takashi FujitaComments: 21 pagesSubjects: Quantum Physics (quant-ph)A unified theoretical treatment is presented to describe the physics of electron dynamics in semiconductor and graphene systems. Electron spin fast alignment with the Zeeman magnetic field (physical or effective) is treated as a form of adiabatic spin evolution which necessarily generates a monopole in magnetic space. One could transform this monopole into the physical and intuitive topological magnetic fields in the useful momentum (K) or real spaces (R). The physics of electron dynamics related to spin Hall, torque, oscillations and other technologically useful spinor effects can be inferred from the topological magnetic fields in spintronic, graphene and other SU(2) systems.

Corkscrew Robot - can you do it?

Here's one for the more creative engineers - a robot running on corkscrews instead of wheels or legs. Tim Lexen, an engineer in Cumberland, Wisconsin, has come up with a novel design for robots. It has a triangular body 18 centimetres on a side, capped by a round lid, and three stainless steel coils 20 cm in diameter and 40 cm long. Each coil is turned by a motor - and by activating a coil, the robot can move in the direction of the coil's axis. "It runs very well on grass, sand, gravel and other outdoor surfaces," Lexen said when he presented his work earlier this month at the IEEE International Conference on Technologies for Practical Robot Applications in Woburn, Massachusetts. However, the prototype has trouble gaining traction on surfaces like polished wood floors. Here's the thing though; Lexen's prototype is only radio-controlled.  A human operator chooses what direction to rotate which screws. Given the idea, I bet the clever folk here could not only replicate the corkscrew drive, but make it autonomous. I'd bet an Arduino or Raspberry Pi would be up to the job. Go on - imagine the kudos of beating the boffins at their own game! New Scientist article. Abstract of Lexen's work. Video of robot in action.

Existentialists, how do you find a meaning for life? Answered

Lately (and by lately I mean for a while now) I have been experiencing existential/nihilist/teen angst. I'm totally detached from reality, especially the future which is what I'm supposed to care about, what everyone cares about. I think that life is essentially meaningless, it came to exist because of a fluke, and it continues to exist because perpetuates itself (evolution). So I've been trying to make life matter to me, existentialist style. But I can't seem to get the knack of it. I don't know what I want out of life, I'm not clear on what exactly there is to want....I'm not even sure that anything is real except me. Lately I've taken to telling myself that things are meant to be, and there is a greater purpose, I just can't comprehend it yet.....which may be the most ridiculous thing I've ever told myself..... I know most people think this stuff, but don't take it seriously. They just go on living. But I just can't....perhaps because these abstract thoughts seem as real to me as everything else (not very)? Sorry if I'm totally incoherent.... HELP. please?

Since it was suggested by CaitlinsDad over here: https://www.instructables.com/community/Requesting-feedback-on-a-Fire-Breathing-Dragon-tes/ Came up with this.

The knight is abstract, it always bothers me when the horse is the only thing with any detail. The pawn is about 1/2" x 1" tall, the queen would be just under 2" tall, the king is about 2 1/4" tall, both by 1" wide, the other 3 are about 1 1/2" x 3/4". It is done in 18g galvanized steel. Anybody still reading? Great! I'd love to get some feedback, good, bad, anything to either confirm it is just the best thing ever OR how it could be improved towards that goal. So don't hold back.

BUG: Small images are no longer being properly cropped square

It looks like an update was rolled out overnight.  In the Instructables browsing pages, the word "featured" has been replaced with "editor's picks".  Obviously, the underlying URL is the same (since it uses a database keyword).  This change hasn't been done in either the forum topics or Questions areas. There's also a bug in the I'bles browsing.  Instead of pictures being centered to fit in the same sized thumbnail on each image, smaller images now take up less space.  This creates problems with sideshow or video labels, as you can see below. UPDATE 10 Nov 2010:  The bug is not in the page browsing, but rather in the image library system.  The three "square" image versions, TINY, SQUARE, and SQUARE2, are no longer being cropped properly to have equal height and width.  Instead, they are simply reduced in size from the original, but keeping the full image's aspect ratio. UPDATE 14 Nov 2010:  Another user has reported noticing that their step-by-step icon images are different sizes.  This is the same bug, as the TINY version is what is used for the step icons. UPDATE 17 Nov 2010:  Well, the cropping seems to be back to square, but instead of the small images being scaled to the right size before cropping, little chunks are just being taken from the middle.  For large, high resolution images, the result is a blurry bit of abstract art.

Super basic resource for learning electric motors

I watch an insane amount of YouTube, particularly woodworking, as designing and building furniture is my big passion in life. I have, however, become more and more interested in learning about motors. It has become increasingly obvious to me that literally, every tool in a workshop is simply a motor that turns something. Saws, drills, sanders, planers, jointers, even dust collectors are all nothing more than a motor turning something around and around in a circle.   I just bought a new Table Saw, and during my 6 months of researching, I read all about 1, 2, 3, and even 5 horsepower motors. Single-phase vs. three phase. rpms, 110V vs 120V vs 220 vs 240V etc etc etc... It was all mostly abstract, as I could tell that higher horsepower means "good" and lower horsepower means "less good." But now, I have a lot of projects that I want to build, but I know nothing about motors.  I've been watching a lot of Matthias Wandel on YouTube, and I want to know everything there is to know about motors. Unfortunately, I don't know anything really about electronics at all. But I feel like learning about motors is a great place to start learning. Does anyone have a book or a resource that literally takes things back to motors 101 for 10 year olds?

Modeling Mathematical Objects for 3D Print in 3dsmax or Blender3d

Hello, everyone.  I'm making my first post here to share some techniques and tips for getting started with polygonal modeling of interesting mathematical shapes, which could be used in 3d printing.  Math objects are quite popular in the 3d printing community due to their seemingly complex visual appearance, and overall unique aesthetic for creation of jewelry and other useful printed objects.  These tutorials are for use primarily with the modeling and animation software, Autodesk 3dsmax, or the free open-sourse Blender 3d.  However, the basic principals of these techniques can be translated to almost any capable polygonal modeling software. 3D Tutorial | Modeling Triply Twisted Torus With Holes | 3dsmax 3D Tutorial | Model A Mobius Strip Pendant | 3dsmax Modeling a Mobius Strip Pendant In Blender 2.73 3D Tutorial | Model a Scherk-Collins Saddle Surface Ring | 3dsmax 3d Tutorial | Voronoi Style Bracelet | 3dsmax Model A Voronoi Style Bracelet In Blender 2.74 These are but an example of nearly a dozen different mathematical and abstract models at my channel.  All tutorials are 100% free, of course, and I'd be happy to help you with any issues you may face along the way.  Keep in mind, in order to follow along with these videos, you will need to use the Autodesk 3dsmax software, or the free Blender 3d software, and have at least some intermediate  experience in polygonal modeling in general. These tutorials are not intended for total beginners to 3d modeling, unfortunately. Enjoy, and I hope you find something useful.

A sunscreen that keeps you in the shade all day long

I have been thinking about a suncreen that will keep shaded all day long. Rather then to move along as the sun changes position during the day, why not move the suncreen so that it always shades the same spot ? To that end, and after some thinking the idea of a movable abstract tree like shape which projects shade on the ground, was come up with. It would be able to move, let the wind pass trough, and because unlike traditional suncreens it would not be a parasol, it would give shade but cooler wind is also possible. Question remain though. Ho do you know which shape will give which shade ? As the screen would have to automove, a GPs with clock and arduino/wire would be needed. In a later step how to deal with excessive wnds would have to be included. There is also a possible cantilever mecanism and the weight of the whole thing. Also possible is to add a solarcell for the energy. As when one side is giving shade the other is pointing towards the sun. So some of the mecanism for it could be used for other things. I wondered if there is some kind of formula, algortirhm where you put height, surface area , shape/coordinates position of the sun, season in it, and the coordiantes of the area which should be shaded, and then run or show or find which shape would work best, but also to use in the arduino/wire. The shade could be be like big leafs that cover each other, like thick crosses, which allow the wind to move through, or other things. Please let me know if this is not so clear.

Overclocking of my Intel Pentium 4 CPU 3.00GHz 2992 Mhz Processor. How can it be done?

A friend of mine introduced me to the idea of over clocking my processor. He said it can be dangerous due to over heating issues. I am willing to add new fans into my PC so long as the speed can be controlled. I will not be able to obtain a better heatsink however (My heatsink is pretty beefy already). Ive done some research but have only been able to find very broad forums. I need to know how to do it, what to do and what not to do, how far past factory specs i can push it beyond and if my mother board with withstand it.. Also i have a follow up question I notice that the system summery stes that i have 1.57GB Avilible physical memory but i have 2.50 GB Installed physical memory. is there any way to overclock the RAM as well?

Very basic electronics kits for 2 yearolds!?

My 2 year old daughter appears to enjoy the very basic geeky things that she's gotten her hands on so far.  Things like plugging headphones into the iPad to listen to music; building things with large Lego blocks; turning torches on and off; playing with little remote-controlled-cars etc etc. I'd like to see how she gets on with some sort of basic "electronics kit" which allows her to experiment a little while teaching her some very basic principals (like circuits require both a power source and a load). All existing electronics kits I've seen would be way to advanced for her.  For example, she's years away from being able to understand what "completing a circuit" means (i.e. any kits which require you to connect both a negative and positive cable from power source to actuator would be way to abstract for her). I'm thinking of making her a very, very basic "electronics kit".  Each component would be in its own little tinted, semi-transparent box. There would be several "sources" of electrical power (small battery pack, PV cells, little hand-cranked dynamo etc).  Each source module would have a single large DC socket to send power to another module.  Each source would produce about 3 volts and would have short-circuit protection. There would be several "actuator" modules like a lamp, motor, door bell, volt meter, radio etc.  These modules would each have a single small DC socket. Cables would have a large DC socket on one end and a small DC socket on the other.  The use of large DC sockets on the power source modules and small DC sockets on the actuator modules should make it mechanically impossible to create a "wrong" circuit (like connecting a battery pack to a  PV cell). And maybe some basic "control" modules like a switch, light-operated switch, oscillator etc.  Each  control module would have both a small DC socket (power input) and a large DC socket (power output to actuator). Each class of module (actuator, controller, power source) would have its own colour. My first question is: does a similar kit exist for purchase? If not, I'll make the kit for my daughter, unless anyone has good evidence that such a project would still be way to advanced for a 2 year old.  Of course, I'll start with the real basics like just a battery module, switch, light and two cables to see how she gets on with it.

Giant Robot Architecture Talk by Greg Lynn in Berkeley

Here is an interesting talk from the Art, Technology, and Culture Colloquium of the Berkeley Center for New Media...Giant Robot ArchitectureGreg Lynn, UCLA & Angewandte, ViennaMonday, Feb 4, 7:30-9:00pm- Note Special Location: Berkeley Art Museum Theater- Enter on Dwight Ave: http://bampfa.berkeley.edu/visit/visitor- Lecture is free and open to the publicAbstractRobots. In my office, my staff keeps asking for more new machines, and every time I get a new machine, I fire two or three people. By extrapolation, in the next few years I will be sitting in an office by myself with a bunch of robots. We have is a very large CNC (computer numerically controlled) cutting machine, a laser cutter, a 3d printer, and soon we will have a robotic articulated arm. All of these things let us do studies of models, which are very important to architects, but what they also let us do is learn machine language. We spend more and more time talking to machines; speaking their language. It is very easy for us to go to any country that has an automobile industry or an aircraft industry and give their machines instructions and do things with these large machines at an architectural scale that is very perfunctory and affordable. The spread of machine language and programming is more significant than the Anglicization of the world. Learning to talk to robots is very important to my field of design.Speaker BioGreg Lynn is a leading pioneer at the intersection of computing, design, and architecture. His architectural designs have been exhibited in both architecture and art museums including the 2000 Venice Biennale of Architecture where he represented the United States in the American Pavilion. His work is in the permanent collections of CCA, SFMoMA, and MoMA and has been exhibited at the Pompidou, Beyeler, Cooper Hewitt, MAK, MoCA, NAI,Carnegie, ICA and Secession museums among others. In addition to his architectural work, his Alessi "Supple"Mocha Cups and his Vitra "Ravioli" Chair are in production and have been inducted into the Museum of Modern Art's Permanent Collection. He received the American Academy of Arts & Letters Architecture Award in 2003. In 2002, he left his position as the Professor of Spatial Conception and Exploration at the ETHZ (Swiss Federal Institute of Technology Zurich) and became an Ordentlicher University Professor at the University of Applied Arts in Vienna.He is studio professor of Architecture at UCLA and the Davenport Visiting Professor at Yale University. Greg Lynn holds degrees in architecture and philosophy and received an Honorary Doctorate degree from the Academy of Fine Arts &Design; in Bratislava. In 2001, Time Magazine named him one of 100 of the most innovative people in the world for the 21st century. In 2005, Forbes Magazine named him one of the ten most influential living architects.http://www.glform.comMore info on the colloquium here.

Free Code: JSLoad!

UPDATE: JSLoad is now hosted on Google Code. You can find the most recent source, revision history, documentation, and can report bugs, there. What is JSLoad? JSLoad is a Javascript file loader that we wrote for Instructables. You give it a set of dependencies and groupings, and it loads the files you need, when your executing code needs them. We're releasing it under the LGPL because we're cool like that, and because we'd like to use any enhancements that other folks come up with. You can download the code at the bottom of this blog post, or check out the test file to see it in action. Why use JSLoad? Generally, we use dependency managers to avoid having to think about all the couplings that exist within our code. A widget we've made may need a whole mess of stuff -- all spread out between different files -- to run. Dependency managers allow us to say, "Give me everything I need for this widget to run," instead of having to figure it out for ourselves, each time, for each widget. Other, well-written javascript package managers exist (e.g. jspkg, YUI Loader, etc.) So why did we write a new one, and what reasons might you have for using it? In a nutshell, JSLoad is small, flexible, and is designed to work on its own, without the need for any heavyweight framework. How does JSLoad work? JSLoad does the basics: you tell it that file 1 depends on file 2, so it loads file 1 first, then file 2. Throw any number of other dependencies into the mix, and JSload figures out the dependency chain and loads the files in the right order. The real usefulness of JSLoad comes with its ability to group dependencies using tags. Tags are arbitrary labels that you can apply to (i.e. make dependent on) any group of files or other tags. Tags can be applied to single files or multiple files. Multiple tags can be applied to a single file. You can even think of your tags as depending upon a portion of a file (say, class within a file containing several classes.) As a result, you can mimic most other dependency structures: Chains, trees, or more complicated graphs. You can tag things that often appear together, that share a certain aspect; whatever your usage calls for. At Instructables, for example, we generally have a base set of widgets and features whose dependencies are primarily tree-like. Those little bits are then collected into larger groupings like "editable" or "commentable"; abstract labels that approximate the kinds of interfaces that are common on our site. Tags are also very useful while refactoring code. Often, because of the flexibility of Javascript, you won't be sure of the best way to split your code across files. Which portions will be used together most often, and should thus be grouped together to reduce HTTP requests? With JSLoad, you can tag the variant groupings, then organize your code as you wish. Your web pages will just call JSLoad the tags as they need them. Over time, you may find that one tag is used much more often than the others. Using JSLoad, you can refactor your code into a more efficient file structure, without changing any of the script calls in the pages that use the code. How is JSLoad used? Here is an example of how to instantiate a new instance of JSLoad: var jsLoader = new JSLoad(tags); JSLoad instances are intended to be singletons. JSLoad was designed to track state (which files have already been loaded, for example) in one central location. The "tags" variable passed to the JSLoad instance is a list of tag dependencies. Here is an example: var tags = [ { name : "baselib" }, { name : "widget", requires : ["baselib"] } ]; As you can see, "tags" is an array of objects, each defining a tag and its dependencies. In the above example, the "widget" tag depends on "baselib." An implicit part of the tags definition is that, by default (and for conciseness), tags refer to files. So, in the above example, the "baselib" refers to "baselib.js" and "widget" refers to "widget.js". If a tag doesn't actually refer to a file, but is an arbitrary grouping of your own design, you can set the "tagOnly" property of the tag to "true": var tags = [ { name : "baselib" }, { name : "widget", requires : ["baselib"] }, { name : "gadget", requires : ["baselib"] }, { name : "dostuff", requires : ["widget", "gadget"], tagOnly: true } ]; In this case, I've created a tagOnly tag called "dostuff." There isn't any actual file named "dostuff.js." Rather, the tag just indicates that it needs both "widget" and "gadget" (and, by implication, "baselib") to be loaded. All three will thus be loaded in the correct order if I ask for "dostuff." How do I ask for "dostuff"? Well, somewhere on my page, I might want to do stuff, and thus inline the following Javascript code: jsLoader.load(["dostuff"], function () { var widgie = new Widget(); var gadgie = new Gadget(); }); This tells my JSLoad singleton to run the anonymous function that is the second argument, and to do so as soon as the "dostuff" tag has all of its dependencies taken care of. I can make my load() calls at any point on the page, requiring any combination of tags, and I can repeat them; JSLoad will take care of creating HTTP requests to get the necessary files only once, only when necessary, and in the right order. You can download the code at the bottom of this blog post, or check out the test file to see it in action. The archive at the bottom of this blog post includes the test file, too. Limitations JSLoad has some limitations, due to its implementation. First of all, JSLoad runs asynchronously, to speed up load time on a page and to allow for nested iframes to load script into the top level context. As a result, if you inline dependent script in your page, JSLoad will need to wrap that script to ensure that it isn't executed before the necessary files are loaded. See "How JSLoad is used" above for details. Second, the list of dependencies you provide to JSLoad needs to be ordered. That means that no file or tag may depend on a file or tag that appears after it. This allows JSLoad to run faster, as it can calculate the dependency tree in one pass, and protects it (and you) from circular dependencies. We may remove these limitations in future versions, or at least parameterize them so you can decide which side of a trade-off you'd like to take advantage of. In the meantime, enjoy!
