    • Euro-Office must default to ODF to be considered "genuinely European", LibreOffice argues

      By MikeK13 · Posted

      What people who support this position of LibreOffice do not understand is that EuroOffice is not made to appease the open source enthusiasts (I am also one) and evangelists. EuroOffice was made because some European companies wanted independence from Microsoft Office Suite, which is something installable on your computer. This move to independence was pushed by public institutions and governments in Europe, as well. Using a proprietary FORMAT as default, does not make you dependent on MS. The actual program does. A format can be changed with a simple update in the future in a dystopian world where MS would manipulate the format to lock others out. However, using MS Office proprietary format, guarantees that all the current documents used by companies, organizations, institutions, etc, will be compatible with EuroOffice and the suite will have the best chances at adoption, especially by slow moving organizations like governments and the public sector. It is as simple as that. For the same reason, even the UI is incredibly similar to MS Office. For the same reason (adoption) the choice was made to be open source. Not because EU particularly loves open source ideologically, but because it gives the best starting point to create trust in the project and amass developers and contributions to the project quickly, to catch up with proprietary projects like MS Office. I don't understand how people don't realize it.
    • Microsoft hides these secret Windows 11 performance boost settings available on every PC

      By WaltC · Posted

      How old is this tip? Seems 15-20 years old? Processor states for the CPU under Windows power options has been a thing for a long, long time. It certainly isn't new or hidden... Also, with laptops it doesn't make any difference what OS you are running, all of them are configured for battery longevity over performance, for obvious reasons.
    • UK to ban under-16s from social media following a six-week trial with teenagers

      By WaltC · Posted

      I can't believe Starmer is still there...his party lost so big. He's a stubborn coot, but this is largely unenforceable, so I would imagine he'll be resigning soon. A key here is for parents to buy their kids phones sans Internet access--and set up the Internet at home, where mom and day can, you know, act like parents instead expecting the government to raise their kids.
    • EA launches in-game advertising platform for brands to "connect with audiences"

      By LoneWolfSL · Posted

      EA launches in-game advertising platform for brands to "connect with audiences" by Pulasthi Ariyasinghe The gaming giant Electronic Arts is exploring more ways to inject real-life brands into its games. Announced today as EA Advertising, the new platform is attempting to make it easier for brands to reach out for deals with the company and put their products inside titles like EA Sports FC, Madden, NHL, Skate, or The Sims. EA revealed that its EA Sports side of the company brings in "hundreds of millions of players across console, PC, and mobile" every year. Fan engagement of these titles was also touted as being "extraordinary," with 23,000 NFL seasons worth of games being played in Madden NFL daily, while EA Sports FC sees over a billion matches a day. “Players come to EA’s games and live experiences every day to play, watch, create and connect,” said David Tinson, Chief Experiences Officer at Electronic Arts. “That gives brands a meaningful opportunity to show up in ways that add value and respect the player experience, while maintaining authenticity in the worlds our teams are building. With EA Advertising, we’re helping brands become part of those moments in ways that are relevant and built for players.” Using the new program EA Advertising, brands will be able to inject their products into games in real-time via dynamic placement. EA says partners will have access to everything from stadium signage in sports games and targeted adverts to in-game content custom-made for the brands. These are described as additions designed to "enhance, not disrupt" experiences. "In these interactive gameplay environments, brands become part of the game itself, reflecting how players engage with advertising in real-world contexts," adds the company "Brands can activate across live environments, tailoring placements to meet campaign objectives, and update campaigns with ongoing optimization informed by aggregated engagement insights." Current real-world brand partnerships EA has built into its games include Visa (EA Sports FC and College Football), Lowe's (EA Sports FC, Madden NFL, and College Football), Red Bull (EA SPORTS FC), Xfinity and Peacock (EA SPORTS FC), and Mountain Dew’s (College Football).
