Tesla’s Biggest Problem Is Its Own CEO

Tesla is Elon Musk. Elon Musk is Tesla. Rarely has a company’s identity been so inextricably linked to its CEO, for better and for worse. For years, this fusion was a superpower, giving Tesla an innovative mystique that captivated investors and propped up its valuation. Now, that same connection has become a massive liability. In a brutal reaction to Elon Musk’s latest political bombshell—the launch of his own political party—investors wiped nearly $70 billion off Tesla’s market capitalization

Public exploits released for CitrixBleed 2 NetScaler flaw, patch now

Researchers have released proof-of-concept (PoC) exploits for a critical Citrix NetScaler vulnerability, tracked as CVE-2025-5777 and dubbed CitrixBleed2, warning that the flaw is easily exploitable and can successfully steal user session tokens. The CitrixBleed 2 vulnerability, which affects Citrix NetScaler ADC and Gateway devices, allows attackers to retrieve memory contents simply by sending malformed POST requests during login attempts. This flaw is named CitrixBleed2 as it closely resemb

Why don't we trust technology in sport?

For a few minutes on Sunday afternoon, Wimbledon's Centre Court became the perfect encapsulation of the current tensions between humans and machines. When Britain's Sonay Kartal hit a backhand long on a crucial point, her opponent Anastasia Pavlyuchenkova knew it had landed out. She said the umpire did too. Television replays proved it. But the electronic line-calling system - which means humans have been fully replaced this year following earlier trials - remained silent. Minutes ticked by.

Show HN: I Got Tired of Calculator Sites, So I Built My Own

I’ve always found that online calculators tend to have bad UIs, especially on mobile. Most of the calculator websites I’ve come across use outdated and inconvenient ways of inputting data, or they format the results in confusing ways. I’ve noticed that fraction calculators (especially mixed fractions) are terrible to use, even on desktop. I haven’t built one of those yet, but it’s something I’m planning to tackle soon. This is a project I’ve always wanted to work on, but I’m relatively new to

What Happens to Tesla When Musk Picks Politics Over Cars?

Tesla is Elon Musk. Elon Musk is Tesla. Rarely has a company’s identity been so inextricably linked to its CEO, for better and for worse.

I'm not losing sleep over Elon Musk's political ambitions

Just a month after his explosive fallout with Donald Trump, Elon Musk is floating the idea of forming his own political party. In a poll on X, 1.24 million of his followers voted, with 65.4 percent saying they would like to see such a thing happen. The America Party would offer “independence” from a political system Musk says is too focused on “waste & graft.” Like so many things Musk says, it’s not worth paying too much attention to unless he puts his money where his mouth is. But, also like so

Tesla shares drop 7% after Elon Musk says he is launching a political party

Elon Musk Calls the U.S. Dollar ‘Hopeless,’ Says His America Party Will Embrace Bitcoin

As details about his new political venture begin to emerge, Elon Musk has confirmed that the “America Party” will embrace Bitcoin, a move that solidifies the party’s anti-establishment and tech-centric identity.

Async Queue – One of my favorite programming interview questions

For the past 7+ years, I've been conducting a programming interview that has been a true personal favorite of mine. It was passed down to me from good friends (Jeremy Kaplan and Carl Sverre, and it was the latter whom I believe invented it). This interview has probably been given by us between 500-1000 times across different companies, and upon googling for "async queue interview", I see tons of results. So, it's probably fine for me to blog about it. My main goal with this blog post is to disc

Elon Musk Is Selling His Political Party Like a Tesla

Less than 24 hours after launching his political party, Elon Musk is already playing hype man for the movement he claims will disrupt America’s broken political system. The richest man in the world took to X (formerly Twitter), the platform he owns, early Saturday morning to promote and to articulate the need for The American Party, his newly announced third party aimed at breaking what he calls the “uniparty” stranglehold of Democrats and Republicans. The move has drawn sharp criticism from su

Elon Musk Forms a New Political Party to Challenge Trump and the Republicans

As he had previously vowed, Tesla CEO Elon Musk officially announced the formation of a new, third political party on Saturday, July 5, 2025. This dramatic move comes just hours after President Donald Trump signed his “One Big Beautiful Bill” into law, a sweeping budget measure that implements massive spending cuts and eliminates nearly all federal climate and clean energy programs, legislation Musk staunchly opposed. The announcement was definitive. “Today, the America Party is formed to give

Elon Musk’s New Political Party Sparks MAGA Backlash Online

The suspense is finally over. Elon Musk, the visionary behind Tesla and SpaceX, officially declared the formation of a new political party on Saturday, July 5, 2025. His stated aim: to challenge the long-standing dominance of both the Republican and Democratic parties. “Today, the America Party is formed to give you back your freedom,” the controversial tech entrepreneur announced on X (formerly Twitter) at 3:46 PM ET.

Log your weight in Apple Health quickly and cheaply with this iPhone-compatible smart scale

After my last WiFi-enabled smart scale broke and refused to connect to the Internet anymore, I sought something simpler and cheaper to replace it. The old scale had all sorts of fancy service integrations that I never used. I just wanted something that would track my weight and report the measurements to the Health app on my iPhone. The Eufy C20 smart scale is what I landed on and I’m very happy with it — and it’s pretty cheap too. Here’s how it works … Firstly, the scale works completely inde

Sam Altman Feels ‘Politically Homeless’ As Frenemy Musk Proposes Third Party

Sam Altman is grappling with his political alignment. The 40-year-old CEO of OpenAI, like many of his fellow tech executives in recent years, has expressed that he does not feel at home in the Democratic Party or the Republican Party. In an extended post on X, Altman lamented the fact that he’s now “politically homeless” and yearns for a technocratic utopia—something his once friend and current rival Elon Musk has also been calling for with his push to form a third party. Hmm…interesting timing,

xAI prepares Grok 4 Code as it plans to take on Claude and Gemini

xAI is preparing the rollout of Grok 4, which replaces Grok 3 as the new state-of-the-art model. Ahead of the rollout, testers on X have again spotted references to a few new Grok 4 models. One of the models is called "grok-4-prod-mimic," which reportedly excels at enterprise use cases like data extraction, coding, and text summarisation. It also possesses deep domain knowledge in finance, healthcare, law, and science. But "grok-4-prod-mimic" isn't the only new model coming to Grok. Another

Stalking the Statistically Improbable Restaurant with Data

Last summer, I wrote about the statistically improbable restaurant, the restaurant you wouldn’t expect to find in a small American city: the excellent Nepali food in Erie, PA and Akron, OH; a gem of a Gambian restaurant in Springfield, IL. Statistically improbable restaurants often tell you something about the communities they are based in: Erie and Akron have large Lhotshampa refugee populations, Nepali-speaking people who lived in Bhutan for years before being expelled from their county; Sprin

Adding calendar events with a screenshot is AI at its finest

Apple’s AI capabilities have been less than impressive to date, but there’s one new feature coming with iOS 26 that’s actually really handy: adding stuff to your calendar with a screenshot. I’ve been testing this feature out for the past few weeks in the developer beta, and I’m pleased to report that it works, easily making it my favorite Apple Intelligence feature so far. That’s admittedly a low bar to clear — and it’s not quite as capable as Android’s version — but it’s a nice change of pace

The 7 Best Kitchen Scales Reviewed by a Former Chocolatier (2025)

It’s hard to overstate the convenience of a solid kitchen scale for home cooks. Digital kitchen scales open up a new world of possibilities when it comes to upping your cooking or baking game, allowing precision in measuring ingredients, consistency in recipes, and efficiency in the kitchen. As more and more recipes are converted to grams (my favorite measuring metric), there’s no reason to put off investing in a digital scale, especially with how affordable these gadgets can be. Most—like our
