Google AI Unveils A New Open Source Library for Array Storage
|
||||
======
|
||||
*TensorStore, a High-Performance Open Source Library for Array Storage, has been introduced by Google AI.*
|
||||
|
||||
The open source C++ and Python framework TensorStore, developed by Google, aims to accelerate the design for reading and writing huge multidimensional arrays. Multidimensional datasets that cover a single large coordinate system are commonly used in contemporary computer science and machine learning applications. These datasets are challenging to work with because customers frequently wish to conduct investigations involving numerous workstations operating in parallel and may receive and output data at unpredictable intervals and varied scales.
|
||||
|
||||
Google Research developed TensorStore, a library that provides users with access to an API that can manage huge datasets without the requirement for sophisticated hardware, to address issues with data storage and manipulation. Numerous storage systems, including local and network filesystems, Google Cloud Storage, and others are supported by this library.
|
||||
|
||||
To load and work with enormous arrays of data, TensorStore provides a simple Python API. Any arbitrary big underlying datasets can be loaded and updated without having to store the complete dataset in memory because no actual data is read or kept in memory until the precise slice is required.
|
||||
|
||||
This is made possible by the indexing and manipulation grammar, which is quite similar to the syntax used for NumPy operations. Along with virtual views, broadcasting, alignment, and other sophisticated indexing features like data type conversion, downsampling, and haphazardly created arrays, TensorStore also supports these.
|
||||
|
||||
Additionally, TensorStore includes an asynchronous API that enables read or write operations to go concurrently. While performing other duties, a software can perform configurable in-memory caching, which reduces the need to deal with a slower storage system when accessing frequently used data.
|
||||
|
||||
Large numerical datasets demand a lot of processing power to examine and analyse. The usual method for accomplishing this is via parallelizing tasks among a sizable number of CPU or accelerator cores scattered across many devices. The ability to analyse individual datasets in parallel while retaining excellent speed has been a key goal of TensorStore. PaLM, brain mapping, and other complex large-scale machine learning models are some examples of TensorStore application cases.

Ubuntu Pro Now Gives You 10 Years of Security Updates for Free
|
||||
======
|
||||
A free Ubuntu Pro plan for everyone to get 10 years of security updates. This is fantastic news.
|
||||
|
||||
![Ubuntu Pro Now Gives You 10 Years of Security Updates for Free][1]
|
||||
|
||||
Canonical has introduced a free tier to Ubuntu Pro which is aimed at personal use and small-scale deployments.
|
||||
|
||||
**Ubuntu Pro** subscription (formerly known as Ubuntu Advantage) was originally offered to enterprises for providing them with extended security maintenance updates to Ubuntu LTS releases for an extra 5 years of updates.
|
||||
|
||||
The free tier has been made available in public beta.
|
||||
|
||||
### Ubuntu Pro for Personal and Data Centers
|
||||
|
||||
![Canonical launches Ubuntu Pro beta][2]
|
||||
|
||||
Currently available as a beta release, the free tier of Ubuntu Pro can be used by individual users or small-scale data centers for a maximum number of five machines.
|
||||
|
||||
With this launch, CEO of Canonical, Mark Shuttleworth said:
|
||||
|
||||
> Since we first launched Ubuntu LTS, with five years free security coverage for the main OS, our enterprise customers have asked us to cover more and more of the wider open-source landscape under private commercial agreements. Today, we are excited to offer the benefits of all of that work, free of charge, to anyone in the world, with a free personal Ubuntu Pro subscription
|
||||
|
||||
The main advantage of Ubuntu Pro over the standard distribution, are the constant security patches.
|
||||
|
||||
![ubuntu pro benefits][3]
|
||||
|
||||
**This is an incredibly good news for users who want stability on their systems without losing out on security updates.**
|
||||
|
||||
The security maintenance updates are pushed out on a regular basis, especially when a new CVE (Common Vulnerabilities and Exposures) is found.
|
||||
|
||||
Users can take advantage of [Livepatch][4] to apply security patches without shutting down their systems. This is included with the Ubuntu Pro subscription.
|
||||
|
||||
Small businesses and individuals can also make use of various tools required for compliance management, support for compliance standards such as PCI-DSS, HIPAA, FedRAMP and as part of Ubuntu Pro subscription.
|
||||
|
||||
**So, more incentives to use Ubuntu for individuals and businesses?**
|
||||
|
||||
> 💡 If you have up to five machines to work with, Ubuntu Pro's free personal tier should be a no-nonsense option to pick over other platforms.
|
||||
|
||||
With the personal Ubuntu Pro plan small-scale users can now take advantage of the 10-year security coverage (*5 Year LTS updates + 5 Year Extended Security Maintenance updates*), **which includes support for an additional 23,000 packages.**
|
||||
|
||||
The launch of this free tier of the Ubuntu Pro subscription can help [Canonical][5] attract more users to use Ubuntu, which is a good thing for Linux adoption among computer users.
|
||||
|
||||
You just have to sign up for a personal Ubuntu Pro subscription on their [official website][6].
|
||||
|
||||
For more details, check out the [official announcement][7].

谷歌 AI 推出新的阵列存储开源库
|
||||
======
|
||||
*TensorStore，一个用于阵列存储的高性能开源库，已被谷歌 AI 创造。*
|
||||
|
||||
谷歌开发的开源 C++ 和 Python 框架 TensorStore 旨在加速读写大型多维数组的设计。覆盖单个大型坐标系的多维数据集通常用于当代计算机科学和机器学习应用程序中。使用这些数据集具有挑战性，因为客户经常希望进行涉及多个工作站并行操作的调查，并且可能会以不可预测的间隔和不同的规模接收和输出数据。
|
||||
|
||||
谷歌研究院开发了 TensorStore，这是一个为用户提供 API 访问权限的库，该 API 无需复杂的硬件即可管理庞大的数据集，以解决数据存储和操作问题。该库支持许多存储系统，包括本地和网络文件系统、Google Cloud Storage 等。
|
||||
|
||||
为了加载和处理大量数据，TensorStore 提供了一个简单的 Python API。任何大型基础数据集都可以加载和更新，而无需将完整的数据集存储在内存中，因为在需要精确切片之前不会读取或保存实际数据。
|
||||
|
||||
这是通过索引和操作语法实现的，这与用于 NumPy 操作的语法非常相似。除了虚拟视图、广播、对齐和其他复杂的索引功能，TensorStore 还支持，如数据类型转换、降低取样和随意创建的数组这些功能。
|
||||
|
||||
此外，TensorStore 包含一个异步 API，可以同时进行读取或写入操作。在执行其他工作时，软件可以执行可配置的内存缓存，从而减少在访问常用数据时处理较慢存储系统的需要。
|
||||
|
||||
大型数值数据集需要大量的处理能力来检查和分析。实现这一点的常用方法是在分散在许多设备上的大量 CPU 或加速器内核之间并行化任务。在保持出色速度的同时并行分析单个数据集的能力一直是 TensorStore 的关键目标。 PaLM、脑图和其他复杂的大规模机器学习模型是 TensorStore 应用案例的一些例子。

Ubuntu Pro 现在免费为你提供 10 年的安全更新
|
||||
======
|
||||
一个免费的 Ubuntu Pro 计划，每个人都可以获得 10 年的安全更新。 这是个好消息。
|
||||
|
||||
![Ubuntu Pro 现在免费为你提供 10 年的安全更新][1]
|
||||
|
||||
Canonical 为 Ubuntu Pro 引入了一个免费计价层，该层针对个人使用和小规模部署。
|
||||
|
||||
**Ubuntu Pro** 订阅（以前称为 Ubuntu Advantage）最初是为企业提供的，用于为他们提供 Ubuntu LTS 版本的扩展安全维护更新，额外更新 5 年。
|
||||
|
||||
免费计价层已在公共测试版中提供。
|
||||
|
||||
### 对于个人与数据中心的 Ubuntu Pro
|
||||
|
||||
![Canonical 启动 Ubuntu Pro beta][2]
|
||||
|
||||
目前作为测试版提供，Ubuntu Pro 的免费计价层可供个人用户或小型数据中心使用，最多可容纳五台机器。
|
||||
|
||||
随着此次发布，Canonical 首席执行官 Mark Shuttleworth 表示：
|
||||
|
||||
> 自从我们首次推出 Ubuntu LTS 以来，主操作系统免费提供五年的安全保障，我们的企业客户要求我们根据私人商业协议覆盖越来越广泛的开源领域。今天，我们很高兴通过免费的个人 Ubuntu Pro 订阅免费向世界上的任何人提供！
|
||||
|
||||
与标准发行版相比，Ubuntu Pro 的主要优势在于不断提供安全补丁。
|
||||
|
||||
![ubuntu pro 好处][3]
|
||||
|
||||
**对于希望系统稳定而又不会丢失安全更新的用户来说，这是一个难以置信的好消息。**
|
||||
|
||||
安全维护更新会定期推出，尤其是在发现新的 CVE（常见漏洞和暴露）时。
|
||||
|
||||
用户可以利用 [Livepatch][4] 来应用安全补丁，而无需关闭他们的系统。 这包含在 Ubuntu Pro 订阅中。
|
||||
|
||||
小型企业和个人还可以使用合规管理所需的各种工具，支持 PCI-DSS、HIPAA、FedRAMP 等合规标准，并作为 Ubuntu Pro 订阅的一部分。
|
||||
|
||||
**那么，个人和企业使用 Ubuntu 的更多激励措施？**
|
||||
|
||||
> 💡 如果你最多有五台机器要用，Ubuntu Pro 的免费个人层应该是一个不折不扣正确的选择，而不是其他平台。
|
||||
|
||||
借助个人 Ubuntu Pro 计划，小规模用户现在可以享受 10 年安全保障（*5 年 LTS 更新 + 5 年扩展安全维护更新*），**其中包括对额外 23,000 个软件包的支持。**
|
||||
|
||||
这个免费的 Ubuntu Pro 订阅层的推出可以帮助 [Canonical][5] 吸引更多用户使用 Ubuntu，这对于计算机用户采用 Linux 来说是一件好事。
|
||||
|
||||
您只需在他们的 [官方网站][6] 上注册个人 Ubuntu Pro 订阅。
|
||||
|
||||
更多详情，请查看[官方公告][7]。
