A team of computer scientists at the University of Massachusetts Amherst, led by Emery Berger, recently unveiled a prize-winning Python profiler called Scalene. Programs written with Python are notoriously slow—up to 60,000 times slower than code written in other programming languages—and Scalene works to efficiently identify exactly where Python is lagging, allowing programmers to troubleshoot and streamline their code for higher performance.
“But Python is crazy inefficient,” says Berger. “It easily runs between 100 to 1,000 times slower than other languages, and some tasks might take 60,000 times as long in Python.”
Programmers have long known this, and to help fight Python’s inefficiency, they can use tools called “profilers.” Profilers run programs and then pinpoint which parts are slow and why.
Unfortunately, existing profilers do surprisingly little to help Python programmers. At best, they indicate that a region of code is slow, and leave it to the programmer to figure out what, if anything, can be done.
Berger’s team, which included UMass computer science graduate students Sam Stern and Juan Altmayer Pizzorno, built Scalene to be the first profiler that not only precisely identifies inefficiencies in Python code, but also uses AI to suggest how the code can be improved.
“Scalene first teases out where your program is wasting time,” Berger says. It focuses on three key areas—the CPU, GPU and memory usage—that are responsible for the majority of Python’s sluggish speed.
Once Scalene has identified where Python is having trouble keeping up, it then uses AI—leveraging the same technology underpinning ChatGPT—to suggest ways to optimize individual lines, or even groupings of code. “This is an actionable dashboard,” says Berger. “It’s not just a speedometer telling you how fast or slow your car is going, it tells you if you could be going faster, why your speed is affected and what you can do to get up to maximum speed.”
Scalene is already in wide use and has been downloaded more than 750,000 times since its public unveiling on GitHub. A paper describing this work appeared at this year’s USENIX Conference on Operating System Design and Implementation, where it won a Best Paper Award.

Alongside its Gemini generative AI model, Google this morning took the wraps off of AlphaCode 2, an improved version of the code-generating AlphaCode introduced by Google’s DeepMind lab roughly a year ago.
AlphaCode 2 is in fact powered by Gemini, or at least some variant of it (Gemini Pro) fine-tuned on coding contest data. And it’s far more capable than its predecessor, Google says — at least on one benchmark.
In a subset of programming competitions hosted on Codeforces, a platform for programming contests, AlphaCode 2 — coding in languages spanning Python, Java, C++ and Go — performed better than an estimated 85% of competitors on average, according to Google. That’s compared to the roughly 50% of competitors its predecessor managed to best on the same subset.
Scrum master on scrum-tiimissä paljon vartijana. Hänen vastuullaan on, että tiimi todella on scrum-tiimi – että tiimi viime kädessä noudattaa scrumin pelisääntöjä.
”Arkipäiväisessä tekemisessä tärkein tehtävä on varmistaa, että tiimi luo asiakasarvoa hyödyntäen ketterää työtapaa”, Nordean kehitysjohtaja Otso Z. Laxenius sanoo. Hänen mukaansa arki syö periaatteellisuuden kovin helposti. ”Scrum masterin tehtävänä on palauttaa ketterät periaatteet tekemiseen.”
Scrumin seremonioista erityisesti päivittäispalaveri, daily scrum, jää erityisen helposti arjen jalkoihin. ”Scrum master saa etenkin kiireessä kuulla usein, että onko pakko pitää dailya, kun olisi oikeasti töitäkin tehtävänä”, Laxenius sanoo.
- QEMU 8.2 adds a new “virtio-sound” device that implements capture and playback from inside a guest using the configured audio backend of the host machine.
- A new VirtIO-GPU “Rutabaga” device that allows various abstractions of GPU and display virtualization. This VirtIO-GPU Rutabaga comes from the Android/CrosVM graphics stack and is intended for use with the Android Emulator on QEMU.
- For Microsoft Hyper-V users is now a new “hv-balloon” device for the Hyper-V Dynamic Memory protocol. QEMU documentation describes this as “virtio-balloon on steroids for Windows guests.”
- Support for UFS emulation via new ufs and ufs-lu devices.
- P2P support for VFIO migration.
- Prep changes for the new IOMMUFD back-end.
- As usual the RISC-V software development continues to be quite active. QEMU 8.2 is supporting a number of new RISC-V ISA extensions, support for virtual IRQs and IRQ filtering, and RISC-V vector crypto v1.0 support.
