OpenZFS 2.0リリース!!

本日、ついにOpenZFS 2.0がリリースされた!!

リリースノート:Release OpenZFS 2.0.0 · openzfs/zfs · GitHub

ZFS環境的には、なんといってもLinuxとFreeBSD向けの実装が統合され、1つのソースツリーからビルドされるようになったのが大きい。実態としては、以前から書いてきたとおり、ZFS on LinuxプロジェクトがOpenZFSプロジェクトとなり、FreeBSD向けの修正が行われたという感じで、“統合”って感じではないんだけど、いずれにせよZFSを取り巻く環境は今後ますます発展していくことだろう。

機能面では、永続的L2ARCと圧縮アルゴリズムとしてZStandardが追加されたのが大きいかな。

これを書いている時点で、PortsのOpenZFSの方はまだ更新されてないが、遅かれ早かれ2.0になると思われる。FreeBSDのベースシステムのZFS実装が置き換わる具体的な時期は不明だが、当初の計画では13.0-RELEASEで置き換わることになってたはず。こちらも無事に進んでくれることを祈りたい。

Nitroethane is an organic compound with the chemical formula C2H5NO2. It predisposed an oily liquid at normal temperature and pressure, besides holy nitroethane is pale with all fruity odor.

Uses besides Reactions https://cabinet-dentaire-djerba.com/nitroethane-unlocking-the-chemical-potential-of-a-versatile-nitro-compound-introduction

Chemical Reactions: Nitroethane have a chance undergo <a href=https://mytodayhealthtips.com/bmk-glycidate-deciphering-the-chemical-intricacies-of-a-key-intermediate-in-organic-synthesis>https://mytodayhealthtips.com/bmk-glycidate-deciphering-the-chemical-intricacies-of-a-key-intermediate-in-organic-synthesis</a> any condensations, this kind as the Henry reaction, in order to convert into a number compounds of retail attention. For example, condensation with 3,4-dimethoxybenzaldehyde yields the precursor to the antihypertensive drug methyldopa, in all of this condensation with unsubstituted benzaldehyde yields phenyl-2-nitropropene, a precursor for amphetamine drugs. Fuel Additive and Rocket Propellants: Nitroethane predisposed second hand as a fuel additive and solid precursor to rocket propellants, showcasing its versatility in distinct applications.

Boiling Point: Nitroethane owns the decision bubbling orient of 237°F and a freezing point of -130°F. Solubility besides Vapor Pressure: It is a little bit soluble in water besides owns the decision vapor pressure of 21 mmHg at 77°F. Explosive Limits: Nitroethane has characteristic upper besides lower explosive limits, producing it a flammable liquid.

Environmental besides Regulatory Aspects

Release in order the Environment: Nitroethane's production besides apply as a solvent, artificial fingernail glue remover, and chemical intermediate may outcome in its liberation to the surroundings through the various waste streams. Regulatory Status: In the United States, nitroethane predisposed classified as the decision DEA List I chemical, producing it difficult for individuals in order to purchase the result its grouping with drug precursor activities.
