Python mutable default arguments cause unexpected shared state, experts warn

Using mutable objects like lists as default arguments in Python functions is a common source of bugs. The default value is created only once when the function is defined, not each time the function is called. This means subsequent calls that omit the argument will inadvertently modify and reuse the same list. Experts recommend using None as a default value and creating the mutable object inside the function to avoid this issue.

Troubleshooting Laravel Database Connection Refused Error

A Laravel application can fail with a SQLSTATE[HY000] [2002] connection error when PHP cannot establish a network connection to the MySQL database server. This indicates a problem with the server's availability, network path, or credentials, not with the application's SQL queries or migrations. The article outlines a diagnostic approach, starting with checking if the database service is running and accessible on the correct port and host. It highlights common causes such as the database server not being started or a mismatch between using localhost (Unix socket) versus 127.0.0.1 (TCP) for the connection.

Research proposes study into why AI voices falter in Urdu-English code-switched ads

A researcher in Lahore has proposed a study on AI voice synthesis for Urdu-English advertising, set for 2026. Current AI voices fail at the precise points in ads where languages switch, losing persuasive prosody. The research aims to analyze the specific acoustic patterns at these switch points, which existing systems do not address. It will create the first annotated corpus of Pakistani code-switched ads to measure the gap between human and synthetic speech. The goal is to develop a voice synthesis system that preserves the persuasive impact crucial for advertisers.

B-Draft trains language model from scratch using inference-only NPU chips

South Korean company B-Draft has successfully pre-trained a small language model from scratch using only inference-dedicated NPU chips, a feat previously considered structurally impossible. The resulting model, named VKORE-46M-NPU, has been released publicly on Hugging Face. The training, conducted on 32 first-generation chips, produced a loss trajectory with a 0.99 correlation coefficient to an identical model trained on a GPU under the same conditions. This breakthrough suggests NPUs could be used for affordable, on-premises AI training, reducing dependency on expensive, high-power GPU servers.

VIDRAFT trains language model from scratch on inference-only NPU chip

VIDRAFT has successfully pretrained a small language model entirely on an inference-only NPU chip, challenging the industry assumption that such chips cannot perform backpropagation. The resulting VKORE-46M-NPU model was trained under identical conditions on both the NPU and a GPU, with the two loss trajectories showing a 0.99 correlation. This demonstrates that the NPU performed numerically equivalent training work despite lacking the hardware paths typically considered essential. The model and its weights have been published on Hugging Face, while the proprietary core training technique remains private for IP protection.
