  • Applying smart thinking to open organization principles [Ed: What "open org"? IBM is not an open organisation but a proprietary and patent bully corporation whose own president (the author of the "open org") quit abruptly]

    Habits have an unfair reputation of being bad things that need to be stopped. But consider this: Automation and habits have many things in common. First, they're both repetitive. They're done over and over, the exact same way. More importantly, they reduce costs (both cost per piece and cost of energy used).

  • IT leadership: 3 ways CIOs prevent burnout

    Fighting employee burnout is a key priority for CIOs, especially as teams deal with the ongoing impact of the pandemic and embrace new hybrid ways of working. But IT leaders are not immune to the impacts of burnout. In order to truly help their employees manage work stress and find work-life balance, leaders have to start with themselves.

    We asked CIOs who recently won the 2022 Houston CIO of the Year ORBIE Awards how they personally protect themselves from burnout. Read their responses for advice on how to maintain a healthy work-life blend while continually finding inspiration at work.

  • 3 E's of effective leadership

    Almost two years ago, I shared what I learned about leadership from my experience in a leadership development program. The takeaway? In order to be a strong leader, especially in times of crisis, it’s imperative to be vulnerable and create a psychologically safe environment for your team.

    I was reflecting recently on my leadership style and how it may have changed over the past two years. In some ways, I am the same person, the same colleague, and the same leader. In other ways, I have evolved and adjusted my style to fit the new ways that we engage and work together.

    Three distinct words came to me during this reflection time (and I do love alliteration!). These three words represent what I think is most important in effective leadership today, maybe more so than ever.

Where Do Files Go When the rm Command Is Issued?

The data itself is not destroyed or shredded; it is only unlinked from the filesystem that references the data and indicates the block as free when you remove it using the rm command.

In this scenario, recovering the files becomes too complex, and it’s a good choice not to rewrite something on your system (ex: copying, moving, installing), which overwrites the unlinked block

    Learn the steps and commands to install Jenkins software on Ubuntu 22.04 LTS Jammy JellyFish or 20.04 Focal Fossa Linux.

    Jenkins is a software common in the field of professional software development. When more than one developer is working on a software project, it becomes confusing when all of their changes are put together. To solve this Jenkins comes in to picture. Jenkins is a Continuous Integration System (CI system) programmed in Java, which is used in agile software development: It ensures that small code changes are always immediately tested and imported into the software. Jenkins was first known as Hudson but after some dispute, all developers involved in this (open source) project decided to rename it to Jenkins.

    Hence, in a few words, Jenkins is an open-source project that helps software developers in development by automating various aspects of software app coding such as building, testing, and deploying…

Kernel: LWN Articles About Linux and LSFMM

Filed under
  • /dev/userfaultfd

    The userfaultfd() system call allows one thread to handle page faults for another in user space. It has a number of interesting use cases, including the live migration of virtual machines. There are also some less appealing use cases, though, most of which are appreciated by attackers trying to take control of a machine. Attempts have been made over the years to make userfaultfd() less useful as an exploit tool, but this patch set from Axel Rasmussen takes a different approach by circumventing the system call entirely.

    A call to userfaultfd() returns a special file descriptor attached to the current process. Among other things, this descriptor can be used (with ioctl()) to register regions of memory. When any thread in the current process encounters a page fault in a registered area, it will be blocked and an event will be sent to the userfaultfd() file descriptor. The managing thread, on reading that event, has several options for how to resolve the fault; these include copying data into a new page, creating a zero-filled page, or mapping in a page that exists elsewhere in the address space. Once the fault has been dealt with, the faulting thread will continue its execution.

    A thread will normally encounter a page fault while running in user space; it may have dereferenced a pointer to a not-present page, for example. But there are times that page faults can happen within the kernel. As a simple example, consider a read() call; if the buffer provided to read() is not resident in RAM, a page fault will result when the kernel tries to access it. At that point, execution will be blocked as usual, but it will be blocked in the kernel rather than in user space.

  • Zoned storage

    Zoned storage is a form of storage that offers higher capacities by making tradeoffs in the kinds of writes that are allowed to the device. It was the topic of a storage and filesystem session led by Luis Chamberlain at the 2022 Linux Storage, Filesystem, Memory-management and BPF Summit (LSFMM). Over the years, zoned storage has been a frequent topic at LSFMM, going back to LSFMM 2013, where support for shingled magnetic recording (SMR) devices, which were the starting point for zoned storage, was discussed.

    Chamberlain began with the news that a zoned storage microconference had been accepted for this year's Linux Plumbers Conference (LPC). He encouraged attendees to submit topics and hoped it was an opportunity to introduce more user-space developers to zoned-storage concepts. LPC will be held September 12-14 in Dublin, Ireland.

  • Retrieving kernel attributes

    At the 2022 Linux Storage, Filesystem, Memory-management and BPF Summit (LSFMM), Amir Goldstein and Miklos Szeredi led a discussion on a new interface for extracting information from kernel objects using the filesystem extended-attributes (xattr) interface. Since Szeredi was not present in Palm Springs, he co-led the session virtually over Zoom audio, which was the only filesystem session with a virtual leader at LSFMM this year. Szeredi's proposal for an interface of that sort had been posted just the day before the session.

    Goldstein started things off by noting that there are several use cases where there is a need for a new API to obtain bits of information from the kernel, so it seems like a good idea to create a common API that can meet those needs. Szeredi proposed the getfattr mechanism, which builds on the xattr interface; Goldstein said that he was happy with the idea, as were Szeredi and Dave Chinner, who suggested the idea a year or so ago. In addition, other than an objection to binary data, Greg Kroah-Hartman was "not unhappy" with the idea.

    Szeredi took over to describe the proposal in more detail. The intent is to be able to get attributes from some kernel objects; those could be mounts or inodes, but processes or other objects are possible as well. There are several existing interfaces for getting this kind of information, but each has a different way to access the attributes, so it would be nice to have a unified interface, he said.

    The xattr API was repurposed for his proposal. It uses a different namespace for the new attributes, however, in order to ensure that legacy code will not break due to unexpected new attributes. For example, listxattr() would not return attributes from the new namespace. One objection to the interface is that it is not efficient enough if there is a need to retrieve multiple attributes. Szeredi said that would need to be tested to see if it is truly a problem, but if so, the API could be extended with a bulk-retrieval mechanism.

  • A discussion on readahead

    Readahead is an I/O optimization that causes the system to read more data than has been requested by an application—in the belief that the extra data will be requested soon thereafter. At the 2022 Linux Storage, Filesystem, Memory-management and BPF Summit (LSFMM), Matthew Wilcox led a session to discuss readahead, especially as it relates to network filesystems, with assistance from Steve French and David Howells. The latency of the underlying storage needs to factor into the calculation of how much data to read in advance, but it is not entirely clear how to do so.

    Wilcox began by describing readahead a bit. If user space is reading a file one byte at a time, Linux does not actually read the data that way; instead, it issues reads for a bigger chunk, say 64KB, which gets stored in the page cache. There is a certain amount of latency between the time a page is requested from the storage and when it appears in the page cache; that latency varies greatly over the wide variety of storage types that Linux supports. For network storage, those types can range from locally stored data on multi-gigabit Ethernet to data stored halfway around the world over decidedly slower links. Similarly, for local storage it can range from a 5GB-per-second NVMe SSD to some "crappy USB key picked up from a vendor at a trade show". There is "a lot of stuff to contend with there".

  • Remote participation at LSFMM

    As with many conferences these days, the 2022 Linux Storage, Filesystem, Memory-management and BPF Summit (LSFMM) had a virtual component. The main rooms were equipped with a camera trained on the podium, thus the session leader, so that remote participants could watch; this camera connected into a Zoom conference that allowed participation from afar. In a session near the end of the conference, led by conference organizer Josef Bacik, remote participants were invited to share their experiences—on camera—with those who were there in person. It was an opportunity to discuss what went right—and wrong—with an eye toward improving the experience for future events.

    Ric Wheeler was first up; he said that aside from the first few minutes where he could not hear anyone, "it was a good virtual experience". Mel Gorman echoed that and noted that it "was infinitely superior to not being able to participate at all". One thing he noted is that the "raised hands" in the Zoom interface were not monitored in some sessions. There were two sessions that he remembered where the speaker asked for objections or other comments and he was left "screaming at the mic". It is difficult to keep an eye on that when leading a session, he said; it was only a minor detraction from the overall great experience.

  • HDMI Is An Attack Surface, So Here’s An HDMI Firewall

    Many years of using televisions, monitors, and projectors have conditioned us into treating them as simple peripherals whose cables carry only video. A VGA cable may have an i2c interface for monitor detection, but otherwise it presents little security risk. An HDMI interface on the other hand can carry an increasing number of far more capable ports, meaning that it has made the leap from merely a signal cable to being a connector stuffed with interesting attack vectors for a miscreant. Is it time for an HDMI firewall? [King Kévin] thinks so, because he’s made one.

    RISC-V International has grown its pile of royalty-free, open specifications, with additional documents covering firmware, hypervisors, and more.

    RISC-V – pronounced "risk five", and not to be confused with the other architecture of that name, RISC-5 – essentially sets out how a CPU core should work from a software point of view. Chip designers can implement these instruction set specifications in silicon, and there are a good number of big industry players backing it.

    The latest specs lay out four features that compatible processors should adhere to. Two of them, E-Trace and Zmmul, will be useful for organizations building RISC-V hardware and software, and the other two could prove important in future, aiding the development of OSes to run on RISC-V computers.

  • Linux Fu: Roll With The Checksums

    We are often struck by how often we spend time trying to optimize something when we would be better off just picking a better algorithm. There is the old story about the mathematician Gauss who, when in school, was given busy work to add the integers from 1 to 100. While the other students laboriously added each number, Gauss realized that 100+1 is 101 and 99 + 2 is also 101. Guess what 98 + 3 is? Of course, 101. So you can easily find that there are 50 pairs that add up to 101 and know the answer is 5,050. No matter how fast you can add, you aren’t likely to beat someone who knows that algorithm. So here’s a question: You have a large body of text and you want to search for it. What’s the best way?

The main reason behind this is that it improves developers’ problem-solving ability to a great extent.

  • [Reposted] You Need to be Wrong (Sometimes)

    “Well-calibrated” means that if you predict something occurs with X% probability, then that event actually occurs X% of the time. Since predictions are often made on one-off events, another way of expressing calibration is that X% of predictions that you made with X% confidence should resolve in your favor. For example, if you make 100 predictions of 100 independent events, each with probability 75%, then you’d expect that (roughly) 75 of your predictions would be “correct”.

  • What willwould a Chromium-only Web look like?

    On the face of it, there is some sense to it – after all, most W3C and WHATWG specifications have been written algorithmically (rather than declaratively) for a while now. Why not just converge on a single actual codebase? That way, interop on things like HTML parsing is perfect, but people can still choose the browser with the features (e.g., privacy protections) that they want.

    It’s also not that far-fetched. Microsoft has already ditched their engine for Chromium; we’re all worried about Mozilla’s health and long-term (or even medium-term) viability, and Apple is only one competition judgement away from having to open up iOS to other engines.

    After all, the code is what determines what browsers are capable of and therefore it defines the shape of the Web. Chromium already has a high market share of browser engines; why not just formalise it?

    Putting aside the many arguments one might raise about diversity, risk management, innovation, and so on, I want to focus on one aspect of this potential change – governance.

  • Some network speeds and network related speeds we see in mid 2022

    On 1G connections, anything can get wire bandwidth for streaming TCP traffic (or should be able to; if it can't, you have some sort of problem). On 10G connections, a path between Linux machines without a firewall in the middle should readily run over 900 Mbytes/sec for a TCP connection without any specific tuning (and without Ethernet jumbo frames). We haven't tried to measure our OpenBSD firewalls recently but I don't think they can move traffic this fast yet. SSH connections aren't this fast; we can count on hitting 1G wire bandwidth but generally not anywhere near close to 10G TCP bandwidth with a single SSH connection.

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.
