Hi,

 

Having a lot of fun lately with Python and pyinstaller is really making things very cool! Initially I just wanted to create 32-bit version of my applications but turns out on Ubuntu the 32-bit version is not working on a 64-bit Ubuntu and vice versa. Is it some kind of restriction on Ubuntu or I have to configure something?

the 32bit libraries aren't installed by default on Ubuntu 64bit (same is true on most other 64bit linux distros as well)

 

to install them run

sudo apt-get install ia32-libs

then you'll be able to run 32bit apps

hmm, bit strange! Not sure why 32-bit libraries are not enabled to begin with. I will take a note of that, thanks!

 

Because you should be running 64bit on a 64bit install, unlike in windows you can just compile all programs to 64bit negating the need for 32

What? Not every program has its source code available for the end user to compile.. you're still at the mercy of the developer for anything outside of the repository, especially if it's not open source.  Pick anything from Steam, proprietary video drivers, etc etc.  Plus you're also negating the fact that some distros are geared towards older hardware, may not even have x64 as an option, or may be using the x86 PAE version of the kernel.  Finally, you're also missing the original point of the question.. PyInstaller.. which turns a Python script into a standalone executable.. compiled in advance, no source.

    • Amazon lays off more staff across Goodreads and Kindle divisions

      By Hamid Ganji · Posted

      Amazon lays off more staff across Goodreads and Kindle divisions by Hamid Ganji Dozens of Amazon employees working on the retailer's book divisions have been laid off. As reported by Reuters, Amazon confirmed that it's cutting jobs across the Goodreads review site and Kindle units, which impacts fewer than 100 workers. Amazon says the recent layoffs across Goodreads and Kindle divisions are meant to improve efficiency and streamline operations. The giant retailer has constantly reduced staff across various divisions over the past few years. According to CEO Andy Jassy, reducing headcounts helps the company to eliminate bureaucracy. "As part of our ongoing work to make our teams and programs operate more efficiently and to better align with our business roadmap, we've made the difficult decision to eliminate a small number of roles within the Books organization," an Amazon spokesperson said. Layoffs recently impacted employees in Amazon's Wondery podcast division, devices and services units, communications, and in-store staff. However, Amazon's Q1 results show the retailer has added about 4,000 jobs compared to Q4 2024. After the Covid pandemic settled down, many companies began laying off thousands of staff they hired during the pandemic to respond to growing demands. The layoff trend among tech firms still exists today, and AI has amplified it. The latest data shows that in 2025, about 62,832 tech employees were laid off across 141 tech companies. Also, 152,922 tech employees across 551 companies were laid off in 2024. More layoffs are expected to occur due to declining economic growth, tariffs, and the expansion of AI across companies. Amazon is also gearing up to double down in AI investments and robotics. The company has recently announced the forming of a new agentic AI team to develop an agentic AI framework for use in robotics. Also, a new report by The Information indicates that Amazon has begun testing humanoid robots for package delivery.

    • OpenAI responds to The New York Times' ChatGPT data demands

      By pradeepviswav · Posted

      OpenAI responds to The New York Times' ChatGPT data demands by Pradeep Viswanathan The New York Times has sued OpenAI for the unauthorized use of its news articles to train large language models. As part of the ongoing lawsuit, the NYT recently asked the court to require OpenAI to retain all ChatGPT user content indefinitely. The NYT's argument is that they may find something in the data that supports their case. Brad Lightcap, COO of OpenAI, wrote the following regarding the NYT's sweeping demand: OpenAI has already filed a motion asking the Magistrate Judge to reconsider the preservation order, since indefinite retention of user data breaches industry norms and its own policies. Additionally, OpenAI has also appealed this order with the District Court Judge. Until OpenAI wins its appeal, it will be complying with the court order. The content defined by the court order will be stored separately in a secure system and will be accessed or used only for meeting legal obligations. Only a small, audited OpenAI legal and security team will be able to access this data as necessary to comply with our legal obligations. As of early 2025, ChatGPT has over 400 million weekly active users, and this data retention order will affect a significant number of them. OpenAI confirmed that ChatGPT Free, Plus, Pro, and Teams subscription users, and developers who use the OpenAI API (without a Zero Data Retention agreement) will be affected by this order. ChatGPT Enterprise, ChatGPT Edu, and API customers who are using Zero Data Retention endpoints will not be affected by this court change.
