Suport technique et veille technologique

Aujourd’hui, les grandes entreprises et administrations publiques hésitent entre continuer à utiliser des logiciels propriétaires ou basculer vers les Logiciels Libres. Pourtant, la plupart des logiciels libres sont capables de bien traiter les données issues des logiciels propriétaire, et parfois avec une meilleur compatibilité.

C’est alors la barrière de la prise en main qui fait peur, et pourtant...

Les logiciels libres

L’aspect « Logiciel Libre » permet une évolution rapide et une plus grande participation des utilisateurs. Les aides et tutoriels foisonnent sur Internet ou sont directement inclus dans le logiciel lui-même.

Enfin, les concepteurs sont plus proches des utilisateurs, ce qui rend les logiciels libres plus agréable à utiliser et conviviaux.

Grâce à la disponibilité des logiciels libres, vous trouverez facilement des services de support techniques et la licence n’est plus un frein à l’utilisation de ces logiciels par votre personnel.

Notre support technique concerne essentiellement les logiciels libres, que ce soit sous forme de services ponctuels ou de tutoriels.

Web3 is going just great [English]  -  Researchers identify an attack strategy actively being used by the second-largest Ethereum mining pool to earn outsized mining rewards

 -  Août 2022 -

Researchers from The Hebrew University have identified an attack on the consensus mechanism used by Ethereum which they describe as risk-free and which can used to "obtain consistently higher mining rewards compared to the honest protocol". They also identified that the attack was being actively used by F2Pool's Ethereum mining pool to attack other mining operations. F2Pool is the second-largest Ethereum mining pool.

By manipulating the timestamps of blocks to be added to the chain, a miner can replace other miners' main-chain blocks with their own blocks, obtaining the fees that would have gone to the other miners. The attack has been called an "Uncle Maker" attack because Ethereum refers to valid but not main-chain blocks as "uncles".

F2Pool co-founder Chun Wang responded on August 8 to the allegations against his mining pool, apparently acknowledging their behavior and suggesting that manipulating a vulnerability in a system is not a "blatant disregard [of] the rules" as the researchers had characterized it. He tweeted: "We respect the *consensus* as is. If you don’t like the consensus, convince [Ethereum developer Tim Beiko] to send me another Announcement and change it." Quote-tweeting a tweet by the lead author of the paper who described F2Pool's technique, he wrote, "I can’t stop appreciate this elegant implementation of what we’ve done over the past two years... A robust system must withstand all kind of tests."
