Trump’s New Labor Stats Guy is a Jan 6 ‘Bystander’ Accused of Unhinged Posts

gizmodo.com Lucas Ropek 2025-10-07 08:05:16

President Trump recently fired Erika McEntarfer, the head of the Bureau of Labor Statistics, accusing her of having “rigged” job reports. In her place, Trump has selected E.J. Antoni, a former Heritage Foundation economist who was photographed at the January 6th debacle (but who claims he was just a “bystander” to the chaos) and who, according to reports from CNN and Wired, formerly ran a Twitter account that posted all sorts of gnarly stuff. Earlier this month, Wired reported that a since-dele

Meta is fixing threads on Threads

engadget.com Unknown 2025-10-07 16:01:23

Meta is finally fixing how threads work on its social network Threads. Prior to this, there was no real way to know how long a thread was or even if a post was part of a longer discussion. The company has made "several changes that display threaded posts more clearly." These include a new "view more" label that indicates a post is part of a longer thread. This is an easy way to instantly know if someone's thoughts continue past an initial post. Meta There's also a new design element that auto

Update, Sep 4: The feature is now live. Find the new details below. While Threads already allows up to 500 characters per post (which is more than enough for casual users used to the microblogging format), it is now testing support for long-form posts through “text attachments”.

That was fast. A week after a new feature for sharing long-form text was spotted in the Threads app, Meta is making the experiment official. Threads users will now be able to append text snippets of up to 10,000 characters to their posts in a feature Meta says is meant to support journalists and creators on the platform.

You know how sometimes you start a game of Minesweeper and immediately get stuck? Like maybe there are some cells that you know are mines, but there aren’t any places that are safe to click. In this example there are five different ways you could fill in the mines in the neighbouring cells. Note that there’s no cell which is safe in every possibility, so there’s nowhere we can safely click to get more information.

Instagram Finally Debuts Native iPad App. It Only Took 15 Years

Following earlier rumors in 2025, iPad users finally saw a dedicated Instagram app arrive on their devices on Wednesday. Since the iPad's original release 15 years ago, Instagram had never been available in the App Store as a download for Apple's tablet. Instead, users had been stuck with the workaround mobile version, which awkwardly failed to stretch to the iPad's larger screen size. It's not clear why Instagram took so long to appear on the iPad.

For the past two years, the U.S. has been supplying tens of billions of dollars worth of military aid to Israel so that it can bomb the living crap out of the civilian population in Gaza. Now, as multiple human rights organizations accuse Israel of committing genocide in the region, America’s billionaire developer president seems to think it’s time to spin the bloodshed into real estate gold.

Triangle Grids (2022)

Grids are great for tactical gameplay of turn-based games because they allow discrete movement steps. That means that you can bind positioning to other resources such as movement points, action points, food, etc. Grids divide the infinite variety of movement options into a few specific ones, which can be considered separately by the player’s tactical mind. The most popular grid types are hexes and squares. But what about triangles? Your browser does not support the video tag. Types of Grids: C

Hi, I have a largish (2 GB) corpus of curated, high-quality text in some low-resource language, and I want to build a model that would provide an advanced "auto complete" service for writers.

U.K. law now requires pornography websites to verify their users’ ages through means such as face scans and driver’s licenses; it also requires that online platforms prevent children from being exposed to adult content (which is why sites like Bluesky and Reddit have begun checking some users’ ages).

Probability of typing a wrong Bitcoin address

I heard someone say that Bitcoin is dangerous because you could easily make a typo when entering an address, sending money to the wrong person, and have no recourse. There are dangers associated with Bitcoin, such as losing a private key, but address typos are not a major concern. Checksums There are several kinds of Bitcoin addresses. Each is at least 20 bytes (160 bits) long, with at least 4 bytes (32 bits) of checksum. The chances of a typo resulting in a valid checksum are about 1 in 232.
