Known as “Scalene,” the profiler — a kind of debugger for performance issues — has been downloaded more than 900,000 times on GitHub. “It’s awesome in general, and amazing for an academic project,” UMass professor Emery Berger, who worked with PhD students Sam Stern and Juan Altmayer Pizzorno on the open-source tool, told IT Brew…

Scalene measures how much time and memory is spent on each line of code — both on average and at peak, [and] how much time is spent in efficient libraries and how much is spent in Python… By selecting a lightning-bolt icon, a user can “leverage the engine that powers ChatGPT to get an optimization” suggestion, Berger said. In one demo he showed IT Brew, an output recommended a less-memory-intensive move to reduce a very large array created by the code…

“If your Python code already runs fast enough, then you don’t need a profiler. But if it’s running slow, I think it’s a very convenient profiler to reach for,” Berger said.

Halo’s Trailer for Season 2 Teases More Covenant

Halo — the TV series — launches its second season on February 8th. But today a trailer premiered during halftime of the pre-Super Bowl football playoff.

Gizmodo reports:
Even though the Covenant are the other side of Halo’s ongoing conflict, the first season of Paramount+’s TV series largely represented them through a human proxy named Makee. With the upcoming second season, the coalition of alien races is set to become a more prominent threat, and that means they’ll be getting more proper screentime.

IGN had written that Season 1 “isn’t a perfect adaptation of the games, but it ultimately succeeds in expanding the series’ mythology and taking a more character-driven approach to Master Chief’s adventures.” This week Paramount+ also released a 28-minute compilation of “Epic Battle Scenes from Season 1, a season which reportedly cost $200 million to film.
And now the entertainment site Collider reports on what comes next:

While on the set for Halo Season 2, Collider’s Steve Weintraub and some other reporters got the chance to sit down with stars Schreiber and Kate Kennedy to discuss how the show will further flesh out the Covenant in the upcoming episodes. Part of that involves expanding their arsenal with new vehicles like the corvette, a class of ships used in the Halo canon by the Covenant for reconnaissance, stealth, and much more. Kennedy placed it among her favorite Season 2 set designs, saying… “It’s huge, and what the set guys did for it, and the art department, is really, really impressive. They turned it around so quickly, and it’s, like, awe-inspiring, it’s huge.”

Aside from making the Covenant more formidable, Season 2 will also focus on making them more understandable. Part of that involves diving into the thought process of key players within the alien faction, including two that Schreiber could tease. “Yeah, we definitely go into the Covenant mind-state, mentality,” he said… In future seasons, Schreiber believes Halo will only continue to develop the Covenant, their motives, and the relationships and allegiances within the coalition as the story of intergalactic war unfolds.

Famed Financial Analyst’s Final Forecast? ‘The Dollar is Finished’ as World Reserve Currency

An anonymous reader shared this report from the The New York Times:

Over his 54 years as a financial analyst, Richard X. Bove perfected the art of grabbing attention… American Banker once called him “the country’s most quotable bank analyst.” Last week, a few hours after completing a spot on Bloomberg television, the 83-year-old announced his retirement. He took that weekend off — and then jumped right back in. In an interview with The New York Times, Mr. Bove (pronounced “boe-VAY”), who goes by Dick, shared a dire outlook on the U.S. economy and his former profession.

“The dollar is finished as the world’s reserve currency,” Mr. Bove said matter-of-factly, perched in an armchair outside his home office just north of Tampa, from which he predicted that China will overtake the U.S. economy. No other analysts will say the same because they are, as he put it, “monks praying to money,” unwilling to speak out on the mainstream financial system that employs them…

As he spoke, a technician was trying to restore his home internet after his final employer, the boutique brokerage Odeon Capital, pulled the plug on his last day…

He sees the offshoring of American manufacturing as the ultimate threat to the financial sector and the dollar, because “the people making the goods elsewhere are getting greater and greater control of the means of production and therefore greater and greater control of the world economy and therefore greater and greater control of money.”

The article notes that Bove was once called “The Loneliest Analyst.”

“One way that’s still true is that he endorses cryptocurrency — an area that few other financial analysts will touch — which he sees as a natural beneficiary of the decline of the dollar.”

Remembering Unix Desktops – and What We Can Learn From Them

“As important as its historically underhanded business dealings were for its success, Microsoft didn’t have to cheat to win,” argues a new article in the Register.

“The Unix companies were doing a great job of killing themselves off.”

You see, while there were many attempts to create software development standards for Unix, they were too general to do much good — for example Portable Operating System Interface (POSIX) — or they became mired in the business consortium fights between the Open Systems Foundation and Unix International, which became known as the Unix wars.

While the Unix companies were busy ripping each other to shreds, Microsoft was smiling all the way to the bank. The core problem was that the Unix companies couldn’t settle on software standards. Independent Software Vendors (ISV) had to write applications for each Unix platform. Each of these had only a minute desktop market share. It simply made no business sense for programmers to write one version of an application for SCO OpenDesktop (also known as OpenDeathtrap), another for NeXTStep, and still another one for SunOS. Does that sound familiar? That kind of thing is still a problem for the Linux desktop, and it’s why I’m a big fan of Linux containerized desktop applications, such as Red Hat’s Flatpak and Canonical’s Snap.

By the time the two sides finally made peace by joining forces in The Open Group in 1996, it was too late. Unix was crowded out on the conventional desktop, and the workstation became pretty much a Sun Microsystems-only play.
Linux’s GPL license created an “enforced” consortia that allowed it to take over, according to the article — and with Linus Torvalds as Linux’s single leader, “it avoided the old Unix trap of in-fighting…

I’ve been to many Linux Plumbers meetings. There, I’ve seen him and the top Linux kernel developers work with each other without any drama. Today’s Linux is a group effort… The Linux distributors and developers have learned their Unix history lessons. They’ve realized that it takes more than open source; it takes open standards and consensus to make a successful desktop operating system.
And the article also points out that one of those early Unix desktops “is still alive, well, and running in about one in four desktops.”

That operating system, of course, is macOS X, the direct descendent of NeXT’s NeXTSTEP. You could argue that macOS, based on the multi-threaded, multi-processing microkernel operating system Mach, BSD Unix, and the open source Darwin, is the most successful of all Unix operating systems.

Did a Lake on Mars Once Contain Life?

UPI reports:

New research published Friday offers hope that the sediment samples picked up by the Mars rover Perseverance could reveal traces of life — if it ever existed on the Red Planet.

The rover already has confirmed an ancient lake on Mars. The new research published in Science Advances shows the Jezero Crater, where Perseverance verified lake sediments, is theorized to have been filled with water that deposited layers of sediments on the crater floor. “The delta deposits in Jezero Crater contain sedimentary records of potentially habitable conditions on Mars,” the research article’s abstract stated. “NASA’s Perseverance rover is exploring the Jezero western delta with a suite of instruments that include the RIMFAX ground penetrating radar, which provides continuous subsurface images that probe up to 20 meters below the rover.”

The research by UCLA and the University of Oslo shows the lake subsequently shrank and the sediments carried by a river formed a large delta… [R]adar images revealed sediments shaped like lake deposits on Earth. Their existence was confirmed by the new research.

Mozilla Says Apple’s New Browser Rules Are ‘as Painful as Possible’ for Firefox

Apple’s new rules in the European Union mean browsers like Firefox can finally use their own engines on iOS. Although this may seem like a welcome change, Mozilla spokesperson Damiano DeMonte tells The Verge it’s “extremely disappointed” with the way things turned out. From a report: “We are still reviewing the technical details but are extremely disappointed with Apple’s proposed plan to restrict the newly-announced BrowserEngineKit to EU-specific apps,” DeMonte says. “The effect of this would be to force an independent browser like Firefox to build and maintain two separate browser implementations — a burden Apple themselves will not have to bear.” In iOS 17.4, Apple will no longer force browsers in the EU to use WebKit, the underlying engine that powers Safari. The change opens the door for other popular engines, such as Blink, which is used by Google Chrome and Microsoft Edge, as well as Gecko, the engine used by Firefox. It also means third-party browsers could become fully functional on iOS without any of the limitations that come along with WebKit.

Apple’s Large Language Model Shows Up in New iOS Code

An anonymous reader shares a report: Apple is widely expected to unveil major new artificial intelligence features with iOS 18 in June. Code found by 9to5Mac in the first beta of iOS 17.4 shows that Apple is continuing to work on a new version of Siri powered by large language model technology, with a little help from other sources. In fact, Apple appears to be using OpenAI’s ChatGPT API for internal testing to help the development of its own AI models. According to this code, iOS 17.4 includes a new SiriSummarization private framework that makes calls to the OpenAI’s ChatGPT API. This appears to be something Apple is using for internal testing of its new AI features. There are multiple examples of system prompts for the SiriSummarization framework in iOS 17.4 as well. This includes things like “please summarize,” “please answer this questions,” and “please summarize the given text.”

Apple is unlikely to use OpenAI models to power any of its artificial intelligence features in iOS 18. Instead, what it’s doing here is testing its own AI models against ChatGPT. For example, the SiriSummarization framework can do summarization using on-device models. Apple appears to be using its own AI models to power this framework, then internally comparing its results against the results of ChatGPT. In total, iOS 17.4 code suggests Apple is testing four different AI models. This includes Apple’s internal model called “Ajax,” which Bloomberg has previously reported. iOS 17.4 shows that there are two versions of AjaxGPT, including one that is processed on-device and one that is not.
