Gartner, IDC were both wildly wrong in guessing Apple's Q4 Mac shipments

1 Comment
Article Image

Two research groups that estimate global PC shipments not only served up incorrect data as fact, but also used the bogus figures to reach entirely false conclusions about Apple's Macs in the global PC market. This isn't the first time they've been so wrong but outlines the lack of accuracy from third-party "sales estimates" as Apple prepares to stop reporting its official sales numbers altogether.

Eight Hidden macOS Features You Can Access With the Option Key

1 Comment
The Option () key – or Alt key, depending on your keyboard layout – can be used to unlock all kinds of features hidden in your Mac's operating system.

Try holding it down next time you access an app's menu bar options, for instance, and you'll often see several tweaked actions available to you.

Additional Finder File actions revealed via the Option key

In the Finder File menu shown above, Open becomes Open and Close Window (if you have a file selected in Finder, selecting this opens the file and also closes the Finder window), Close Window becomes Close All, and Move to Trash becomes Delete Immediately, amongst other options.

Below are just some of our favorite uses for the Option key in macOS. Feel free to share any other Option key actions you frequently use in the comments section at the bottom of this article.

Finder View Actions


In Finder's List view, hold Option and click the triangle next to a folder to expand it, and the contents of any subfolders nested inside will also be revealed.


In Column view, you can also resize all columns in a window by Option-clicking on the column selector.

Menu Bar System Icons


Holding the Option key when you click menu bar system icons often reveals hidden actions. Option-click the Wi-Fi icon for example and you'll see extensive information on the currently connected network.


Do the same for the volume icon and you'll be able to change not only the audio output device but the input device, too. Elsewhere, Option-clicking the Time Machine icon will let you Browse Other Backup Disks, and you can also Option-click the Notifications Bar icon to turn it on and off.

Safari Browser


To clear all history including cached website data and cookies, you would select Safari -> Clear History... from the Safari menu bar. If you hold the Option key though, Clear History... becomes Clear History and Keep Website Data.


Hold down the Option key when you click a tab's close button, and all other tabs will close except for that one. In Safari's File menu, the Close Tabs option also becomes Close Other Tabs with Option held down.

Preview File Formats


When you come to save or export a file in Preview, Option-click the Format dropdown to get access to several more available file types.



Open Preference Panes


If your Mac's keyboard has icons printed on some of the functions keys, you can press them to perform special features. For example, pressing the F11/12 keys with speaker icons adjusts the volume.


If you hold down Option when you press one of these keys, this will open the System Preference pane associated with the feature. Option-F11/12 opens the Sound pane, for instance.

Scrollbar Behavior


In the General preference pane, you can select between two forms of scrollbar behavior: Jump to the next page and Jump to the spot that's clicked.


You can actually switch between the two behaviors on the fly: simply Option-click anywhere in a window's scrollbar to jump to that location in the open document or webpage.

Force Quit Apps


If an application is acting up, hold down Option and right-click its icon in the Dock to reveal a Force Quit action in the popup menu.


You can also Option-click an app icon to bring its window to the forefront and simultaneously hide another app's active window.

Resize Windows


When you drag your mouse from one side or corner of a window to resize it, you can hold the Option key to resize the dimensions of the window from its center point instead.

Adjusting from one corner affects all corners with the Option key held

Turning The Deep Note Into A Game

1 Share

One of the most famous pieces of computer-generated music is the Deep Note, the audio trademark for THX. It begins with a dozen or so voices, randomly tuned between 200 and 400 Hz, then glissandos to a frequency spread of three octaves. Put that through a few thousand watts of a speaker system, play it before Jedi, and the audience will be listening.

The original THX Deep Note was created on hundreds of thousands of dollars worth of hardware running 20,000 lines of code, but that was in 1983. Now we have cheap microcontrollers, so of course, you can now fit the Deep Note in your pocket. You can even make it a game. That’s exactly what [Bob] did with his Deep Synth. It’s the Deep Note, in a Game Boy-ish format.

The hardware for this build is the 1Bitsy 1UP, a retro-inspired handheld game console from [Bob]’s friend [Pitor]. Onboard the 1Bitsy is an STM32 F4 running at 168 MHz with a 2.8″ LCD, SD card reader, and the traditional Game Boy control scheme. All the games are up to you.

[Bob] wrote an audio driver for the 1UP, but needed a good audio demo. Since the Deep Note was a good enough demo for Lucasfilms, it would obviously be a good enough demo for a microcontroller. In far less than 20,000 lines of code, [Bob] made the 1UP polyphonic, and it was surprisingly fast enough to synthesize around thirty oscillators. It actually sounds like the Deep Note, too. You can check out a video (and audio) of that after the break.

Vigilante server administrator is fixing insecure routers without permission

1 Comment and 2 Shares

A Russian hacker who calls himself "Alexey" is infiltrating insecure networks and adding security patches to Latvian-made MikroTik routers so they "can't be abused by cryptojackers, botnet herders, or other cyber-criminals," reports ZDNet. Alexey claims to have secured over 100,000 MikroTik routers so far. A security expert told ZDNet that over 420,000 MikroTik routers have been hijacked to mine cryptocurrency on the sly.

Alexey has not been trying to hide his actions and has boasted about his hobby on a Russian blogging platform. He says he accesses routers and makes changes to their settings to prevent further abuse.

"I added firewall rules that blocked access to the router from outside the local network," Alexey said. "In the comments, I wrote information about the vulnerability and left the address of the @router_os Telegram channel, where it was possible for them to ask questions."

But despite adjusting firewall settings for over 100,000 users, Alexey says that only 50 users reached out via Telegram. A few said "thanks," but most were outraged.

The vigilante server administrator says he's been only fixing routers that have not been patched by their owners against a MikroTik vulnerability that came to light in late April.

Banksy’s Barely Believable Batteries

1 Comment

Nearly a decade ago my friend [Dru] gave me an unforgettable tour late at night of Stokes Croft, the inner suburb of Bristol known at the time for its counterculture and artistic scene. It’s a place dominated by building-sized graffiti and murals, and it has a particular association with the Bristolian street artist [Banksy]. If you’ve not seen a Banksy in the wild, the place to do it is by Bristol Saturday night street lighting to the sound of passing revelers and traffic on the A38.

[Banksy] is famous aside from his anonymity, for his pranks upon the art world. The (real) elephant in the room or the Dismalland theme park are his stock in trade, and you may have seen another prank of his in the news in the last day. One of his paintings, the 2006 Girl With A Balloon sold at auction for over a million quid, and as the gavel fell a hidden shredder in the picture frame sprang into life and partially shredded the canvas. The report suggests that a number of [Banksy]’s associates were present at the event, and that one of them was detained with a device that might have been a remote control trigger for the shredder. The quote from Sotheby’s Europe head of Contemporary Art, [Alex Branczik] says it all: “We got Banksy’d”.

[Banksy]’s cool and all that, but where’s the hack? The artist briefly put up a video with a few details, but aside from showing us a row of craft knife blades and a tantalizing but fleeting glimpse of a few equipment enclosures, it’s short on technical details. We can see what appears to be at least one motor, and those white boxes may be batteries, but that’s it.

This hasn’t stopped some fevered speculation as to how the feat was achieved. A home-made shredder would require a significant amount of readily available power, and since this one has seemingly lain undetected within the frame since 2006, that power source needs to have possessed both exceptional  energy density and retention. We can’t imagine many consumer grade batteries in 2018 being able to retain a charge for twelve years, so how on earth did he do it? Our best guess is that a primary battery was involved, as anyone who has found a neglected Duracell in a box of electronics from their youth will tell you it’s not unknown for decent quality alkaline cells to live well beyond their shelf lives, and other chemistries are specifically designed with that property in mind. Even so, for the cells to power a receiver circuit in standby for so long would certainly tax their capabilities, so it has also been suggested that a concealed switch could have been flipped by a [Banksy] accomplice during the viewing phase to activate the system. There are still so many unanswered questions that it’s certainly piqued our technical curiosity. Sadly we don’t know [Banksy] to ask him how he did it, but we welcome speculation both informed and otherwise in the comments.

Our own [Joe Kim]'s tribute to the work in question.

Meanwhile the piece itself lies half shredded and protruding from the base of the frame. On the face of it that’s ruined the painting as an artwork, but of course this is a Banksy. Normal rules seem not to apply, so the notoriety it has received will no doubt mean that its shredded remains are an artwork in themselves, and possibly even one worth more.

Banksy owners worldwide are no doubt now paying a huge amount more attention to the artist’s frames than previously, but Hackaday readers need not worry. Our London Unconference logo and stickers featured a [Joe Kim] homage to the Banksy in question, which we can guarantee does not incorporate an artist’s shredder.
