A Chrome Extension for Being a Jerk

What do you do to someone you want to make suffer, slowly? Specifically, at around 70% speed. To [Stephen], the answer is clear, you hit them where it really hurts: YouTube.

Creatively named “Chrome Engine,” [Stephen]’s diabolical Chrome extension has one purpose: be annoying. Every day, it lowers playback rate by 1% on YouTube. It’s a linear progression: 100% the first day, 99% the second day, 98% the third day, etc. It only stops 30 days later, once it hits its target rate of 70% the original speed. This progression is designed to be slow enough not to be noticed. Its icon is nothing more than the standard Chrome icon as [Stephen] firmly believes in the tactic of hiding in plain sight.

But that’s not all, it’s the minute details that drive the ball home. For instance, rather than using local storage to keep track of playback speed, the Chrome sync storage is used. This ensures that, as long as the extension is installed, playback rate will be synchronized between all of your friend’s(if you can even call them that) devices. It even targets casual YouTube users: [Stephen] has specifically designed their extension so that it won’t drop playback by more than 1% at a time. If the victim goes on vacation, the playback speed won’t drop when they’re away and will resume as soon as they’re back.

The last feature, the one [Stephen] is the proudest of, is that the extension manages to keep the YouTube speed controls working as intended. If the victim tries to play at half speed, their videos will be at half speed … of the slower playback rate set by the extension. And it gets even better! You may not know this if you don’t dally around with playback rates, but the audio tends to stop playing when videos are reduced below 50% of their original speed. Fear not! [Stephen] has accounted for this idiosyncrasy! If the victim selects a speed at or above 0.5x, a minimum cap is added so that the actual playback rate will be equal to or above 0.5x. If they select slower than this, they don’t expect sound anyway, so all bets are off.

Check it out here, may your friends (frenemies?) beware. We’re adding it to our April Fools arsenal, even if it is a bit early.

Hackaday Links: April 17, 2016

There have been really cool happenings in the CNC world for the past few years. There is a recent trend of portable, handheld CNC machines. Yes, you read that correctly. This SIGGRAPH paper demonstrated a handheld router with a camera and a few motors that would make slight corrections to the position of the router. Load in a .DXF or other vector file, and you become the largest CNC machine on the planet. We saw it at one of the Maker Faires, and about a year ago the team soft launched. Apparently, the Shaper router is gearing up for production and [Ben Krasnow] got the first look with a full 17-minute demonstration of [Ben] fabricating parts out of aluminum. It looks like a great tool, and we can’t wait to see this thing in production.

Octoprint is the best way to give a 3D printer a web interface. The dev for Octoprint, [Gina Häußge] used to have a sponsor for developing Octoprint. They’re gone now, which means it’s time for [Gina] to start a Patreon. If you use Octoprint, you know it’s worth more than a dollar a month.

Really bad USB power supplies are nothing new around these parts. There are cheap USB supplies that don’t have any fuses, don’t have any circuit protection, and are noisy as hell. This is the worst USB power supply the Internet has to offer. It’s from one of the relatively new designs of USB power supplies that steps down mains voltage to five USB A ports. [bigclive]’s teardown revealed this was passing half wave mains voltage to the USB ports. It can light up a light bulb. It can kill your phone. The fault? A pinhole in the insulation between the windings of the transformer.

Electronic conference badges are getting excessive, but they can be so much cooler. Here’s Atmel’s take on a high-end conference badge. It has a display, sensors, WiFi, Bluetooth, runs Android, and has 512MB of RAM, 4GB of Flash. It’s a freakin’ mini tablet meant to last for three days.

Speaking of Atmel, they’re having a few growing pains in the merger with Microchip. Employees coming to Microchip from Atmel are getting their severance benefits cut in half. Apparently, the severance benefits given to Atmel employees were not communicated to Microchip before the merger.

Raspberry Pi Zeros are back in production. There’s also going to be a mysterious new feature. Is it WiFi? No, it’s confirmed not to be WiFi. How about Ethernet? Bluetooth? an RTC? Full size HDMI port? Actual pin headers? Audio port? Improved CPU / RAM? No, children. It’s none of these.

C.H.I.P., the nine dollar computer that made some waves last summer, has on-board Flash storage. That means you don’t need to put an image on an SD card. The folks behind C.H.I.P. have recently improved the method for flashing a new OS onto their tiny board: a Chrome plugin. Yes, this sounds completely bizarre, but Chrome plugins are becoming increasingly popular for USB gadget wizardry. You can program an Arduino with Chrome and log USB power profiles with a USB tester and Chrome. You will ride eternal, shiny and chrome.

Mooltipass Installation Process is Now Dead Simple

In a few weeks the Hackaday community offline password keeper will reach a crowdfunding platform. This is a necessary step as only a high production volume will allow our $80 early bird perk target. We’ll therefore need you to spread the word.

Thanks to the Chromium development team, a few days ago the Mooltipass installation process became as simple as installing our app & extension. As you may remember, our device is enumerated as composite HID proprietary / HID standard keyboard. This makes it completely driverless for all operating systems and enables standalone operation as the Mooltipass can type logins and passwords selected through its user interface. Management communications are therefore done through the Mooltipass HID proprietary interface, which Chrome 38 now natively supports through its chrome.hid API. The simpler our installation process is, the more likely the final users will appreciate the fruit of our hard labor.

As our last post mentioned there’s still plenty of space for future contributors to implement new functionalities. Our future crowdfunding campaign will allow us to find javascript developers for the remaining app & extensions tasks and also implement other browsers support. Want to stay tuned of the Mooltipass launch date?

Polaroid Catcher make Print Screen do what it says

polaroidcacher_2

As part of their coursework at ITP New York a group of students developed the Polaroid Catcher. It’s a way to make your digital experiences more permanent. When you have something on-screen that you’d like to keep as a memory you can print the screen on this old Polaroid camera. Of course you’re not going to get the chemical-filled container you may remember from ages past. But we thing you’d agree the nostalgic camera makes a nice enclosure for a modern image printer.

The workings of the system are shown off quite well in the clip after the break. But we’re always interested in the particulars of how they pulled it off. The system uses a Google Chrome extension to capture what is being displayed in the browser. Before the image is sent to the printer the user has the opportunity to frame up the subject of the photo. Once decided, the image is pushed to a Bluetooth photo printer using some scripts written by the team.

Recording audio with Chrome using HTML5

recording-audio-with-chrome

The Dubjoy project was stopped dead in its tracks when the newest version of the Google Chrome browser stopped using Adobe’s flash plugin and transitioned to their own called Pepper Flash. The aim of development was to produce a browser-based editor for translating the audio track of a video clip. After a bit of head scratching and a lot of research they decided to try ditching the use of Flash and implemented a way to record audio using HTML5.

There were quite a few issues along the way. The initial recording technique generated raw audio files, which are not playable by Chrome’s HTML5 audio player. This can be worked around by buffering the raw audio, then converting it to a different format once the recording is finished. The user also needs to monkey with the Chromes flags to enable HTML5 audio. So they did get it working, but it’s not yet a smooth process.

We love seeing the neat stuff you can do with HTML5. One of our favorites is the use of a tablet’s accelerometer as a browser game controller.

Hacking Facebook to remove the social value facade

We see [Ben Grosser’s] point that all the metrics found on the Facebook user interface make the experience somewhat of a game to see if you can better your high score. He thinks this detracts from the mission of having social interactions that themselves have a value. So he set out to remove the ‘scores’ from all Facebook pages with a project he calls the Facebook Demetricator.

You can see two UI blocks above. The upper offering is what a normal user will see. The lower is the page seen through the lens of the Demetricator. [Ben’s] feels it doesn’t matter how many people like something or share something, but only that you are genuinely interested in it. With the numbers removed you’re unlikely to follow the herd mentality of only clicking through to things that are liked by a huge number of people. He explains this himself in the clip after the break.

The Demetricator works much like the Reddit Enhancement Suite. It’s a browser add-on for Chrome, Firefox, and Safari that selectively strips out the metrics as the page renders.

Chrome in the Pwn2Own Contest

Google has announced that it will be sponsoring a $20,000 prize at the 2011 CanSecWest Pwn2Own Contest. $20,ooo will be given to the first person to escape Chrome’s sandbox through Google-written code in the first day. If researchers are unsuccessful on the first day, then days two and three will be opened up to non-Google-written code. In addition to the cash, there is also a Google CR-48 running ChromeOS offered as a prize, but it will not be the actual platform used to hack Chrome. We look forward to seeing what comes out of this contest.
