Necro Malware Infects 'Modified' Spotify, WhatsApp

"Modified" versions of popular apps have helped distribute a nasty piece of Android malware. The tactic expanded the reach of the Necro Trojan despite Google's security checks. Necro was able to survive for some time before discovery, largely because the infection wasn't obvious to users. Its main purpose was to hijack phones and use them to make money for the people behind the malware. This included displaying paid ads in the background so that users didn't see them, but the scammers were able to claim revenue from advertisers.

The makers of an AI model claim it can take control of a computer and complete tasks such as completing forms. The latest version of "Claude" takes a screenshot and counts pixels to figure out how far to move the cursor. Anthropic, which made Claude, say this is the first time a publicly released AI model has the capability of "computer use". It defines this as "looking at a screen, moving a cursor, clicking buttons, and typing text. The goal is to allow the model to carry out tasks which go beyond simply generating text or images in line with a user's instructions. Instead, it could actually ... (view more)

Textifi: How to OCR Hard Copy Printed Material Even in Airplane Mode

By www.inclusiveandroid.com
Published On :: Tue, 22 May 2018 17:27:16 +0000

Textifi by Virtual Eye is a simple OCR app that doesn't require a data or wi-fi connection. The Play Store link is
https://play.google.com/store/apps/details?id=textifi.virtualeye.iohl=en_US

the interface is straight-forward. In the top right corner is a button for turning on the flashlight/torch, and across the bottom are buttons for detecting text, copying text to the clipboard, and reading the text out loud again. There is no menu icon, and there don’t seem to be any app settings.

To use Textifi, do the following:

• Turn on the flashlight (if necessary).
• Center your phone's viewfinder over the printed page.
• Tap the Detect Text button. Recognition is fairly quick. If nothing happens after a second or two, tap the screen again.

Once text is recognized, it is read automatically. If you want it to be repeated, tap the Speak Again button, and if you want to save it, tap the Copy button, then use TalkBack's editing menu to paste the text into a notepad app.

This app’s OCR results are great, but the key is to position your camera right. I was sitting in my office at school going through junk mail. If I positioned the camera by putting my elbow on the table next to the printed page and holding my hand up in the air, results were very good, almost as good as the Eye-D app by GingerMind Technologies. With Eye-D, recognition was pretty good even if I didn’t keep the camera level; with Textifi, recognition was great if I held the camera right, but results were bad if I wasn’t careful.

force dark mode across android OS version 10 for low vision users

By www.inclusiveandroid.com
Published On :: Sat, 28 Dec 2019 03:26:08 +0000

Step 1Enable Developer Options

To force dark mode across all apps, you need to enable a specific developer setting on your device. You'll need to locate the developer options in your system settings, which is hidden by default.

To get started, open the main Settings menu by either selecting "Settings" from the app drawer or by pressing the gear icon in the Quick Settings menu (the menu that appears when you swipe down from the top edge of any screen).
From there, scroll to the button of the menu and select "About phone." Next, choose "Software information."
Now's the fun part. Scroll down and tap on "Build Number" seven times in rapid succession. You will be prompted to input your PIN, gesture, or password. Once you enter the requested information, you will be returned to the previous page, and you'll see a toast message saying "Developer mode has been turned on."
(this is for a Samsung device but should be close for all other devices)

Step 2Force Dark Mode to All Apps

Since this feature is mainly used for developers to see what their apps look like without any extra tweaks for dark mode, your mileage may vary. Some apps do seem to work quite well with the setting enabled, which is good news for the app developers too. At the same time, some apps will have mismatched background colors, fonts, or icons also — so keep that in mind when enabling this setting.

From the "Developer options" main screen, you need to locate a setting that mentions forcing or overriding dark mode. For Galaxy users, Samsung has opted to call this "Force Dark mode," while Google and OnePlus users need to look for "Override force-dark." Once you locate the proper setting, simply flip the switch to the on position to enable it across the entire system

AI Companies Hit Development Hurdles in Race for Advanced Models

By slashdot.org
Published On :: 2024-11-13T14:01:00+00:00

OpenAI's latest large language model, known internally as Orion, has fallen short of performance targets, marking a broader slowdown in AI advancement across the industry's leading companies, according to Bloomberg, corroborating similar media stories in recent days. The model, which completed initial training in September, showed particular weakness in novel coding tasks and failed to demonstrate the same magnitude of improvement over its predecessor as GPT-4 achieved over GPT-3.5, the publication reported Wednesday. Google's upcoming Gemini software and Anthropic's Claude 3.5 Opus are facing similar challenges. Google's project is not meeting internal benchmarks, while Anthropic has delayed its model's release, Bloomberg said. Industry insiders cited by the publication pointed to growing scarcity of high-quality training data and mounting operational costs as key obstacles. OpenAI's Orion specifically struggled due to insufficient coding data for training, the report said. OpenAI has moved Orion into post-training refinement but is unlikely to release the system before early 2024. The report adds: [...] AI companies continue to pursue a more-is-better playbook. In their quest to build products that approach the level of human intelligence, tech firms are increasing the amount of computing power, data and time they use to train new models -- and driving up costs in the process. Amodei has said companies will spend $100 million to train a bleeding-edge model this year and that amount will hit $100 billion in the coming years. As costs rise, so do the stakes and expectations for each new model under development. Noah Giansiracusa, an associate professor of mathematics at Bentley University in Waltham, Massachusetts, said AI models will keep improving, but the rate at which that will happen is questionable. "We got very excited for a brief period of very fast progress," he said. "That just wasn't sustainable."

Dynamics of Saccade Trajectory Modulation by Distractors: Neural Activity Patterns in the Frontal Eye Field

By www.jneurosci.org
Published On :: 2024-11-13T09:30:19-08:00

The sudden appearance of a visual distractor shortly before saccade initiation can capture spatial attention and modulate the saccade trajectory in spite of the ongoing execution of the initial plan to shift gaze straight to the saccade target. To elucidate the neural correlates underlying these curved saccades, we recorded from single neurons in the frontal eye field of two male rhesus monkeys shifting gaze to a target while a distractor with the same eccentricity appeared either left or right of the target at various delays after target presentation. We found that the population level of presaccadic activity of neurons representing the distractor location encoded the direction of the saccade trajectory. Stronger activity occurred when saccades curved toward the distractor, and weaker when saccades curved away. This relationship held whether the distractor was ipsilateral or contralateral to the recorded neurons. Meanwhile, visually responsive neurons showed asymmetrical patterns of excitatory responses that varied with the location of the distractor and the duration of distractor processing relating to attentional capture and distractor inhibition. During earlier distractor processing, neurons encoded curvature toward the distractor. During later distractor processing, neurons encoded curvature away from the distractor. This was observed when saccades curved away from distractors contralateral to the recording site and when saccades curved toward distractors ipsilateral to the recording site. These findings indicate that saccadic motor planning involves dynamic push–pull hemispheric interactions producing attraction or repulsion for potential but unselected saccade targets.
