If you have just the right kernel, and a copy of your CPU key, and a second unbanned Xbox 360, you may be able to reactivate your machine. But how many people have those things available to them? Undoubtedly an Xbox 360’s desirability is greatly diminished if Xbox Live is removed from the equation. This is something Nintendo could learn from when it comes to the Wii (no online multiplayer with New Super Mario Bros Wii?… Really?). So whether you are the one who was banned, or you decided/were tricked in to purchasing a banned console, what are you going to do with it now that online play is out of the picture?
We’ve seen the console emulating SNES games and even XBMC run with the help of Ubuntu. Leave us a comment and tell us if you are planning to just go without Xbox Live, use the machine as a desktop running Ubuntu, or spearhead the effort to repurpose this powerful (and flawed) hardware platform. Will you go out and capitalize on cheaper hardware, or have you been burnt by the grim reality of a crippled rig?
[Cory Doctorow] has published a novel about the near future and a couple of hackers who can make anything from the stuff lying around. We like a good sci-fi novel, and have no shortage of recommendations (go read Snow Crash) for those who need them. We’re adding ‘Makers’ to our must read list.
Not only is this book about you, but its release most likely agrees with your life philosophy. You can download this book, right now, for free, legally. This is because it has been release under the creative commons license. Best of all, if you like the book and want to make a donation, you are directed to purchase a book on behalf of a school or other program that has requested a copy but doesn’t have the funds to acquire it themselves.
So, buy the book if you want a physical copy, download it if you prefer that method, but either way we think this is better than stealing the printed word.
Today we’re going to take a look at writing scripts for the Greasemonkey add-on for Firefox. This add-on allows us to use JavaScript to make changes to the way webpages are displayed on our browser. These changes can only be seen by a copy of Firefox that is running a particular script. As an example, we’re going to write a script that adds a border to the banner image of each article on Hack a Day by overlaying the image you see above. Find out how it’s done after the break.

If you give a mouse a cookie, he will ask for a glass of milk. If you give a team of geeks a box full of parts ranging from aluminum to plywood to motors to RF interfaces, they will build a robot. Introducing Best Robotics, a volunteer group that gives schools a box of hardware and 6 weeks to build a robot that will compete against other schools for the title of champion.
This past Saturday the17th, the OKBest regional competition was held and I, HaD writer [Jakob], was lucky enough to be invited personally to not only watch – but compete. Check out our full breakdown after the jump. Read the rest of this entry »
It’s hard to believe that we haven’t covered this one before. If you enjoyed out Barcodechallenges from last week, perhaps now is the time for you to take the Python Challenge. We made it through the first 18 levels about a year back but with a total of 33 levels we’re not even close to being finished.
This is an excellent opportunity to learn Python if you’ve never tried it, or test your skills if you’ve already got them. We’d suggest using IDLE which is available as part of the Python language download. Because Python is an interpreted language, IDLE allows you to try out each line of the code you are writing and add it to your program as you get different sections working.
The levels start out fairly easy and require some sniffing around, such as looking at the source code, and dissecting images with Python’s various libraries. As you pass each level, you will be granted access to the Python Challenge forums in order to see how others solved the level. By solving each level and then seeing what different solutions entail you grow your knowledge of the language and reinforce your understanding of how to use it.
He printed out one piece of paper for each different enemy, mother ship, laser beam, and player vehicle. The human-based controller is used to move the pieces in all directions. When it comes time for a row to move downward, the pieces are removed from the game grid and relocated to their new position using a scotch-tape-actuator.
We think the most successful part of this hack was [fidepus'] ability to integrate sound effects into the controller system. The human-based controller puts out mono sound with a “pew-pew” for laser blasts and a “dirnk-dirnk… dirnk-dirnk” for the enemy movements.
Although there is no code nor a schematic provided, we think this system shouldn’t be too hard to reverse engineer.
Yesterday we issued a barcode challenge in honor of the Barcode’s birthday. Congratulations to [The Moogle] for winning this challenge. His submission offers a very detailed explanation of how he solved the puzzle using Photoshop, OpenOffice Calc, and some web resources. We’ve got a detailed writeup on it after the break.
Honorable mentions go to [nex] for putting up a Java solution and to [jwmaag] for showing a Python solution. Finally, kudos to all who used a CueCat in one way or another to decode the string. Just having one of those still around is pretty hack-it-y.
Because of the ubiquity of Barcode scanners and online image translation programs the challenge might have been a bit too easy. Do you think you’re up for a greater challenge? Download the new barcode and get to work. This one should be quite a bit harder to decipher. Once again, leave a comment that includes the message stored in the Barcode. Please remember, only entries that solve the puzzle and include a full description of the process will be considered. Good luck, and let the games begin.
Update: It only took [JP] 19 minutes to post a correct solution to the new Barcode. Great work!
This morning we logged into Google to find a Barcode instead of the normal logo (how strange that Google would change their graphic!). Apparently today is the anniversary of the Barcode. This method of easily labeling items for computer scanning is used for every type of commodity in our society. But do you know how to get the cryptic information back out of the Barcode?
Here’s the challenge: The image at the top of the post was created by the devious writers here at Hack a Day. Leave us a comment that tells us what the message says and explains how you deciphered it. There are programs that will do this for you and some smartphones can do this from a picture of the code, but we’re looking for the most creative solutions.
The winner will be decided in a totally unfair and biased way and gets their name plastered all over Hack a Day (and possibly slandered a bit). So get out there and start decoding that machine-readable image.
By now you’ve probably heard something about Google Wave which saw a private preview release last week. The video above is an eight minute overview of the core functionality that the Wave offers. Wave development was based on the premise that email, invented 40 years ago, has not kept pace with our working needs as a technological society. Wave looks to improve on the email model by combining real time chat features, in line conversations, and web tools like document sharing and real-time translation.
The team here at Hack a Day uses a collaborative effort to bring you the best hacks we can find. To do so, we use a combination of email, instant messaging, document sharing, IRC, and old-fashioned conference calling. We’re waiting patiently for our invitation and although we’ve been skeptical of some past Google offerings, we hope the advertised features of Google Wave will allow us to improve our team coverage for the benefit of our readers.
Are you already using Google Wave? Please share your experiences with us in the comments.
Google has unveiled their latest web app. It’s called Google Sidewiki and makes it easy to “Contribute helpful information to any webpage”. We’re not quite so sure. If you have the Google Toolbar installed on your browser, Sidewiki allows you to open a side-panel, add your comments about the page, and read the comments of others.
In a Utopian Internet (Utopernet?) the world’s most predominant experts on all subjects would be browsing websites dropping off clairvoyant nuggets of wisdom like Greek oracles. In reality, letting anyone add to any web page does not equate to instant insight. We’re all familiar with long comment threads and forum posts that contain very low percentages of useful information.
Google considered this “white noise” as a possible problem and implemented a ranking system for which comments are displayed first. This raises another flag, will this become a type of advertising? At some point in the future will comments linking to other pages be ranked based not only on popularity, but on a kickback to the Big G in return for increased exposure?
There is also the consideration that web pages might not like what comments are being left in Sidewiki. We’ve noticed that emails referencing the Labor Movement often have link advertisements in Gmail about how to prevent Unionization. What would the Sidewiki for pages covering controversial topics such as religion, sexual persuasion, and abortion look like?
We will admit this is a well intentioned idea with a lot of potential. But everything depends on how well it is executed.
