What [Jan] has built is a 100% browser-based emulator for an Intel 80486DX2-66 PC. Obviously, it’s not just a CPU that’s being emulated here—[Jan] has gone so far as to throw in the motherboard and ISA/VLB adapter card emulation necessary to make this a real and functioning computer that runs inside a solitary browser tab.
It’s all written in ES6 JavaScript. It will happily run SeaBIOS, VGA BIOS, FreeDOS 1.3, and a whole bunch of classic games, like Wolfenstein 3D, Duke Nukem, and DOOM. There’s even a control panel where you can configure the PC how you like, from storage to expansion cards and all the rest.
Once upon a time an emulator was an application you had to download and run, hoping all the while that your new machine had enough grunt to emulate the classic hardware of your desires. These days, we have endless piles of CPU cycles to throw at everything and you can do it all within a browser. Or even on a tiny microcontroller, if you feel like it!
— Xbox Chief Operating Officer Helen Chiang has suddenly left Microsoft after 21 years with the company, just months after landing the role in July. Her past roles include leading Mojang and the Minecraft franchise.
Verge first reported the news on Friday, citing a memo from Xbox CEO Asha Sharma that did not disclose the reason for her departure.
An Xbox spokesperson was likewise mum on details. “We don’t discuss individual personnel matters. We’re grateful for Helen’s years of service and wish her well,” the company said in an email to GeekWire.
Xbox has undergone a massive reorganization that included Chiang’s appointment, roughly 3,200 job cuts through the fiscal year — about 20% of the Xbox workforce — the spinoff of four game studios and a plan to dramatically flatten management.

— More leadership changes are underway at SeekOut, a Bellevue-based recruiting startup launched in 2017. The company announced Monday that co-founder John Tippett is now president, moving from his role as chief client officer.
In April, SeekOut CEO and co-founder Anoop Gupta retired and passed the reins to enterprise software veteran Sean Thompson. In August, co-founder and chief technology officer Aravind Balatook over as CEO. Thompson is now listed as an adviser to the board.
Tippett will lead day-to-day operations and work with Bala “on the company’s direction,” according to a press release. SeekOut said it wants to integrate AI tools into customers’ operations to reduce recruiters’ workload.
SeekOut is No. 68 on the GeekWire 200, a ranked index of the Pacific Northwest’s top startups.

There are some devices which achieve electronic immortality, it’s likely that you have used a few of them yourself. The 555 timer of course, or the 741 op-amp. [ElectronicsNotes] is here with another candidate that might not have been on your mind as you read the previous sentences, and it’s a transistor. The 2N3055 is an NPN power transistor, no, THE NPN power transistor, that has found its way into an astounding array of devices over the last six decades or more.
For such a ubiquitous device one might imagine that there’s not much new to know, but the video delivers on that front. Here as well as probably for you the 3055 has always been an epitaxial device whose quirks you likely know well, but originally it was something different. It used the hometaxial construction process on its launch in the early 1960s, but in the mid 1970s it was replaced by a version with the same capabilities but using the epitaxial process. The consequent higher Ft required modifications to circuits using the device to stop unwanted oscillation.
Where this is being written there are several 2N3055s, in the by now rather old office audio amplifier, in a bench power supply, and probably elsewhere too. It’s been superseded in many ways and its TO3 case now feels antiquated, but it will probably never entirely go away. Meanwhile if you’d like to read about another iconic 1960s device that never went away, we have you covered.

Last year, we reported on Red Viper, a Virtual Boy emulator that added a splash of Super Game Boy-style color to Nintendo's famously failed red-on-black "portable" 3D headset from the '90s. Now, a new emulation experiment, VBoy Color, has taken the concept to a higher level, using a tile-based palette system that allows for many more distinct colors in each individual Virtual Boy frame.
Rather than simply replacing the Virtual Boy's four shades of red with four different colors, VBoy Color's readme files explain how the emulator's game-specific Color Packs can assign a distinct four-color palette to each 8x8 tile in a Virtual Boy scene. That means the emulator can differentiate between green pipes, grey platforms, and red brick wall in Mario Clash, for instance, even though all those in-game objects share the same overlapping red hues in the original game.
The Game Boy Color-esque results feel like being transported into an alternate history where Nintendo invested in a full-color display rather than cheaper red LEDs for the Virtual Boy hardware. The increased contrast between differently colored elements is particularly welcome in games like Jack Bros. or Vertical Force, where the original red-on-red display often makes it hard to differentiate the player-character from busy red background elements.
Unknown hackers hijacked more than 300 Tor exit nodes and reconfigured them to favor unencrypted email traffic and redirect SSH connections through servers they controlled, a researcher reported Tuesday.
The hijacking began in late August, when, according to Tor volunteers, the attacker used a valid password that had been reused to gain access to a Tor management server. The attacker then installed Ebury, a backdoor written for Linux that was discovered 12 years ago.
Mysteries remain
Then the attacker connected from the management server to a second Tor server, called Switzerland2, through SSH, using an RSA key that, for unknown reasons, investigators couldn’t find among Switzerland2’s authorized keys. With administrative control of Switzerland2, the attackers installed Ebury there as well. Finally, the attacker reconfigured settings on two exit nodes that Switzerland2 hosted.

"What we're finding in today's warfare — we see it with Ukraine, we see it with U.S. operational units — that targeting cycle is much faster," Will Cocos said.
The Ottawa Police Service’s tactical unit has added a Roshel Senator armored vehicle fitted with a hydraulic assault ramp that can lift officers to second-floor windows and rooftops in seconds, giving Canada’s capital the same Canadian-built armored vehicle that Ukraine has used in large numbers on the battlefield. U.S. manufacturer Patriot3 announced that its LIBERATOR […]
If you need a micro-manipulator, you probably already have a good idea of what it does. For example, you might be moving a probe over an IC die or wafer. You might be looking at something through a microscope. The key is moving something in very small, precise increments along three axes. An open-source design for a micro-manipulator has seen significant improvements lately. You can see several videos about the device below.
The device uses stepper motors, parallel kinematics, and miniature ball joints to achieve precise motion. The recent version 4.0 update fixes a few problems. According to the GitHub page:
Self-collision during homing fixed.
Connection of the ball joint block with screws only was not well constrained and could be rotated a bit.
No reliable way to ensure consistent linkage rod length
Unnecessary ball joint friction
Accurate ball position heavily dependent on print quality and corner rounding
Rubber bands could not be changed or removed once glued in.
We’ve covered earlier versions of this device, and we were watching the improvements to the ball joints. Since then, the project has updated much of its mechanical design and documentation, and it has also changed the API that drives it. It can even use tools in g-code now to support things like fine control over laser engraving.
If you prefer something old-school manual, consider a 3D-printed one.
