What if Twitter and Google had a baby? Twoogle!
Posted by Tyler Wall in Search engine on May 22nd, 2009
There has been plenty of buzz this past week regarding Twitters new search engine and I must admit I am impressed. I won’t go into in this article but I will be doing a post that will be specific to Twitter. This post is about the combination of the Google search engine and Twitter’s code-named Twoogle.
Basically this is a search engine mash-up by our friends at Browsys. Browsys is a folder system for links and resources. Now I can’t say that I would recommend Brosys because Diigo does the same thing an much much more. But the Twitter and Google search engine that it provides is a very handy tool that can be used.
How can this help in education?
- Two searches at once saves time
- Utilize the power of both search engines.
Wolfram: A New Take on Search Engines
Posted by Tyler Wall in Search engine on May 21st, 2009
Wolfram|Alpha via kwout
This past week a new challenger arose to test it’s might against the very powerful Google. Its task is a great one as Google dominates the western world but it appears that Wolfram doesn’t intend to play by the same rules. Instead of the user (you and I) searching for webpages that can bring the answers that we seek, we simply type in the the question to the answer we seek and Wolfram gives an answer.
So how good is it? Actually very good, it’s math and arithmetic is exceptional and should be feared as it seeks to put mathematicians out of work, try it by typing in “x^2 sin(x)”. Also try typing in “n=np”, one of the most persistent unsolved questions within computer science. Or perhaps try typing in your name to see statistics on how often it is used in the world. I also typed in “how tall is the empire state building?” and it promptly gave me a very detailed answer. So instead of searching for several minutes and trying to find a well cross-referenced answer I have it in seconds with Wolfram.
Will it replace Google? No, Google’s place is carved in stone but Wolfram may have a place of its own carved out if subsequent releases impress as much as this did.
I think I should also say that Wolfram isn’t the first search engine to try it’s hand at this sort of searching feature. True knowledge has been out for a little over a year now and has the same sort of search functions (see my article on search engines). But so far I am more impressed by Wolfram.
To test out some of the more humorous answers that it gives you try these searches on for size.
- To be or not to be?
- How much wood could a woodchuck chuck?
- How old are you?
- Where am I?
- How many angels can dance on the head of a pin?
- 88 MPH
- What’s the answer to life?
- Hello
- What’s the speed of an unladen swallow?
How can this be used in education?
Again I am going to refer you to the articles I wrote on search engines.
Twitter It!280 slides to a better course
Posted by Tyler Wall in Presentation on May 20th, 2009
I have run across many online Powerpoint replacements but the one I like the most is 280 slides. Now just so I am not too biased I will list some alternatives at the bottom of the page and will likely write a review of them in the future.
As I mentioned earlier 280 Slides is an online replacement/supplement for Microsoft’s PowerPoint or Apple’s Keynote and it is by far the sleekest and sexiest of all the online presentation tools. It is very full featured and allows you to add videos, pictures, text, shapes and even upload powerpoint files.
280 slides also plays nice with online/rich media making it ideal for engaging presentations. It looks good, is easy to use, and you can even try it out without having an account. 280 slides even allows you to download your presentation to a Powerpoint file so you can use it offline in those instances that the internet connection is a bit sketchy.
How to use this app in education?
- Instead of posting your Powerpoint to an LMS just give a link to your online version.
- Students don’t need to own Powerpoint and you will be the one that is saving them money.
- Have your students create their presentations here and perhaps have them critique each others work.
- You can have access to your presentation from anywhere and any computer, no more needing to have Powerpoint on all your computers saving you money.
- You can use it less as a focal point for presentations and more as a supplement to presentations.
These are just a few examples of how to replace Powerpoint with 280 Slides. In the future I will compile a list of how to effectively use any presentation application in your classroom without causing the yawn factor.
Twitter It!Phone Fun for Podcasting
Posted by Tyler Wall in Podcasting on May 19th, 2009
Phonecasting is a simple way of creating podcasts, all you need is a phone and an account on Phonecasting. With both of those you can phone into the number that they give you, talk, and you are actively recording a podcast from just about anywhere through your cell phone. You can also set it up so anyone can listen to your podcast from their phone or cell phone just by calling a different number that you get from your Phonecasting account.
But what about iTunes U? What if I want to use iTunes U as the way for my students to access my podcasts? Well you can easily download the podcasts that you create on Phonecasting (only the ones you create because we respect copyright) and then you can upload it to iTunes U. Problem solved, all the benefits of both these great tools.
Phonecasting has many other options that allow you to create groups, rss feed, and other great social media goodies but I will leave that exploration up to you if you want to use the extra functionality. The reason I won’t go into that is due to it being slightly more difficult to set up, nothing too intense but I have a feeling people just want an easy way to create a podcast.
How can I use this for education?
Podcasts are great for so many different reasons so I will try to give a few examples of how they are good and a few examples of why to use Phonecasting to create your podcasts.
Podcasts
- Deliver lectures that are always accessible for the student
- Deliver added benefits content (introduction to yourself, explanations, readings, daily course tips, etc ) to students like videos and audio
- Record your computer screen (need to use a different tool like Jing) to easily show students how to do common or complex tasks on the computer
Why use Phonecasting?
- I can record almost anywhere, even on a bus or while I am walking the dog.
- Its easy to record
- I can still download my podcasts
- People can listen to my podcast from their mobile device
A New Look
Posted by Tyler Wall in Uncategorized on May 17th, 2009
I thought it was about time for a bit of an updated look to the blog so don’t be scared all is still right with the world. On a side note I am back from holidays and will be posting regularily agian in the upcoming week so stay tuned.
Twitter It!My head is in the clouds but so are my files.
Posted by Tyler Wall in File Management/Storage on May 13th, 2009
About a year ago I was looking for a good solution to share large files that email couldn’t handle (20+mb), I also needed a few other things that I wanted it to do like:
- Sync files automatically across multiple computers.
- Have access to my files regardless of the computer that I am using i.e. read a PDF from an internet cafe computer.
- Collaborate with people via sharing large files.
- Store files online.
Luckily I found a tool to help with all of that and more, Dropbox. Here is a highlight reel of what Dropbox offers:
- 2 GB free storage space online
- File syncing across multiple computers
- OS independent
- Large and small file sharing via public folders
- Photo sharing via photos folder (includes a web interface web gallery)
- Public folder sharing where multiple Dropbox accounts can have access to specified folders and all accounts gain syncing power to constantly be updated with new files in that folder.
- Invisible syncing and through the web interface you can see Dropbox activity.
- Web interface to access your files while away from your computer
- A public folder that allows you to put up files, grab a url from the file, and give the link to whomever and they can download the file without downloading Dropbox. Try it out for yourself by clicking here. http://dl.getdropbox.com/u/17187/Dropbox%20public.pdf and here http://dl.getdropbox.com/u/17187/division%20of%20power.html . as you can see it allows you to link right to html documents and flash files.
To use Dropbox you just download the software install it and it will create a folder in your computer called, you guessed it, Dropbox. It runs in the background and only syncs when you add a file or take one out of the folder. Install Dropbox on any computer you want to sync files across and it will run in the background making sure that the Dropbox folder is synced.Watch this video to better understand what Dropbox has to offer http://www.youtube.com/watch?v=maQrWC-raFQ and go here for a tour of dropbox http://www.getdropbox.com/tour#1 .
So how could you as an educator use it?
- Well how about posting important files for download into your public Dropbox folder and sending the link to all your students so they can download it?
- What if you are working with another instructor or content expert, you could set up a collaborative folder so you both would be up to date with what the other has done.
- Leave your work computer at work and know that those files will be on your home computer for you to work on later.
- Have your students all get dropbox accounts and you could set up a folder where they can send put up their assignments like an assignment dropbox.
- With an account your students could have group collaboration and you would be able to see their progress (as long as you are invited into their group folders) and who is most active and it keeps track of versions and if a file has been deleted which would reduce the odds of cheating.
- Use it to archive important files (you can undelete deleted items and even restore different versions of the same file)
- Whatever you want!
So how do I (Tyler Wall) use Dropbox? Well I have a fellow comic aficionado back in my home town and we are creating a web comic together so I created a new folder in Dropbox and invited him to it. We now both have access to the folder (and no one else) and if I put up a new drawing it syncs to his computer and it is like sharing a folder on the web. I also use it to backup important files, all in folders that no one else has access to.
It has revolutionized the way I collaborate on a large scale project. I haven’t seen my friend in over a year but I feel like we haven’t missed a beat with thanks to Dropbox.(and a few other online tools). Without Dropbox collaboration would be much more difficult.
So if you have Dropbox and use it regularly or have ideas of how to use it for education by all means post a comment and let me and everyone else know your great idea.
Twitter It!Image and paint editors
Posted by Tyler Wall in Image Editing, multipurpose on May 4th, 2009
My last article focused on the compression side of image editors and I tried to focus on the easiest to use options for that specific purpose. While writing that article I felt that I needed to focus on image editors that act more like a full featured photo and image manipulation program like Photoshop. So here is a list of a few online editors in order of what I would be most likely to use.
Sumo paint
http://www.sumopaint.com/web/
online painting/photo manipulation program. One of the most robust in its field with a focus on illustration and painting. It’s editing features are in the top of the online field and my choice as the best of the best.
Adobe Express
https://www.photoshop.com/express/landing.html
A stripped down photoshop that is all online and free (limited). If you create an account you will get access to a few more options and it still remains free. It’s focus is on photo manipulation in a basic way.
Splashup
http://www.splashup.com/
Online image editor that works really well but could be considered on the difficult side if you have never worked with image editors before. It also boasts easy sharing to popular picture sharing sites like flickr, facebook, and picasa. No registration is required to start drawing but to really draw the power of it you should sign up.
Picnik
http://www.picnik.com/
Online image editor that works really well and is very easy. No registration is required to start editing but to fully realize the application requires a paid registration. This one has the most fun filters of them all but lacks some of the other features that make the others really great.
Synfig
http://synfig.org/Main_Page
Synfig is an open source vector animation application very much like Flash. It works on a PC but not Mac as of now and will be a very difficult program to get into for novice and pro alike.
Pencil
http://www.les-stooges.org/pascal/pencil/
Pencil has no image manipulation or fancy filters, its purpose is for frame by frame animation. It’s very old school but still a very fun, easy application and gives you instant gratification.
How can you use these applications for education?
- Create your own graphics for courses
- And you can refer to my last article for some ideas
What are your ideas for useful ways these types of applications can be used in education?
Twitter It!Speed up your Applications with Smaller Images
Posted by Tyler Wall in Compression on May 1st, 2009
Resizing images can be a pain especially if you don’t have the appropriate hardware and more importantly software like Photoshop. I have found a few free (sometimes limited) tools that resize images quickly, easily, and you are even able to correct colors or add special effects.
Here they are:
Picresize:
http://www.picresize.com/
Pros-extremely easy to use and allows you to resize (shrink only), crop, add effects and even change the type of file. No-account required!
Cons- slow to download resized image if you use the percentages resize. So if you use the manual sizing it works great.
Reshader:
http://reshade.com/online-image-resizer/add-image
Pros- resize both ways, preset sizes to choose from, add effects. No-account required!
Cons- all limitations are exclusive to the free version, limited to only 3 images per day, limited resolution size that you can upload (4000 x 4000).
Pixenate:
http://pixenate.com/
Pros- most options for editing the photo (resize, rotate, brighten, redeye, crop, drawing etc), still fairly easy to use, live preview of changes, upload directly to flickr. No-account required!
Cons-
Photoshop online:
https://www.photoshop.com/
By far the most powerful of all but by far the hardest to use. If you have experience in photo editors or want to get some then this is the one for you. to save any edits you make you also need to have an account.
Resizem:
http://www.resizem.com/
I am only putting this one on as a warning to not use it. At the time of my testing there were some major flaws that compromise what can be done with your picture. For instance if I upload a picture called markhead.jpg and then edit it and someone in New Zealand decides they want to upload a picture that they have called markhead.jpg then they will see the picture that I have uploaded and not thier own. Obviously a major flaw and once they fix it I will let you know. It is otherwise a good application.
How can these apps be used in education?
- Resizing photos and image for their course
- Make your file size smaller so its faster
- Add captions to mundane images
- Have students make their file sizes smaller to ease your inbox
Thats what I have now I would like to hear what you have.
