  • F2FS File-System Adding Zstd Compression Support In Linux 5.7

    Being introduced by Linux 5.6 is optional F2FS transparent data compression support that was implemented with LZO and LZ4. Now for the Linux 5.7 kernel there is Zstd compression support on the way.

    Flash-Friendly File-System (F2FS) maintainer Jaegeuk Kim today merged a patch from a Huawei engineer for supporting the Zstandard compression algorithm with this file-system level compression support. On Linux 5.7 and later it means setting compress_algorithm=zstd when mounting an F2FS file-system can enable this Zstd compression capability.

  • Microsoft discloses new Windows vulnerability that’s being actively exploited

    The flaw involves the Adobe Type Manager Library, which helps Windows render fonts. “There are multiple ways an attacker could exploit the vulnerability, such as convincing a user to open a specially crafted document or viewing it in the Windows Preview pane,” according to Microsoft. The vulnerability has a severity level of “critical,” which is the company’s highest rating.

    There isn’t currently a patch available to fix the flaw, though Microsoft’s advisory notes that updates to address security vulnerabilities are usually released as part of Update Tuesday, typically scheduled for the second Tuesday of every month. That means, in theory, the next Update Tuesday is scheduled for April 14th.

  • macOS, Windows 10 and Ubuntu Hacked at Pwn2Own 2020

    macOS, Windows 10 and Ubuntu were some of the software that fell to exploits on day 1 of Pwn2Own 2020. A total of $180,000 was up for grabs for 9 bugs in 3 categories, and hackers were able to defeat the security mechanisms in three of the most popular desktop operating systems out there.

    Due to coronavirus, the annual Pwn2Own event was held virtually, instead of in Vancouver, Canada. The hackers had prepared exploits in advance and sent them to organizers to demonstrate in a live presentation to all participants.

  • HashiCorp Accelerates Multi-Cloud Transformation Efforts

    "The practical reality for most companies is that they will adopt multi-cloud in some capacity," Armon Dadgar, co-founder and CTO of HashiCorp, told ITPro Today. "So the day-to-day reality and the challenge for companies becomes how to operationalize that."

Programming: micro.sth, RProtoBuf, Perl and Python

  • Introducing micro.sth

    Many developers turn their noses up at PHP, but I have a soft spot for it. For me, it's the most approachable programming language by far. It feels intuitive in a way no other languages do, and it makes it possible to cobble together a working application with just a handful of lines of code. So whenever I can't find a tool for a specific job, I try to build one myself. The latest project of mine is a case in point. I was looking for a simple application for keeping a photographic diary, and I was sure that I'd be able to find an open-source tool for that. I searched high and low, but I came back empty-handed. Sure, there are plenty of static website generators, but I'd prefer something that doesn't require me to perform the write-generate-upload dance every time I want to post a quick update. And I need something that I can use not only to maintain a simple diary, but also store notes, manage tasks, and draft articles -- all this without getting bogged down by configuring templates, defining categories, and tweaking settings. And because I want most of my content to be private, I should be able to protect access to it with a password.

  • Dirk Eddelbuettel: RProtoBuf 0.4.17: Robustified

    A new release 0.4.17 of RProtoBuf is now on CRAN. RProtoBuf provides R with bindings for the Google Protocol Buffers (“ProtoBuf”) data encoding and serialization library used and released by Google, and deployed very widely in numerous projects as a language and operating-system agnostic protocol. This release contains small polishes related to the release 0.4.16 which added JSON support for messages, and switched to ByteSizeLong. This release now makes sure JSON functionality is only tested where available (on version 3 of the Protocol Buffers library), and that ByteSizeLong is only called where available (version 3.6.0 or later). Of course, older versions build as before and remain fully supported.
