8 Best Open Source CRM Software

Filed under
OSS

CRM stands for Customer Relationship Management. A CRM software enables the companies to interact with their potential and existing customers, understand and manage their requirement. This improved the relation of the organization with customer and you know that a happy customer brings profitability to the business.

No matter how big your team is (small business or a big firm), a CRM software always comes in handy when you want to keep things organized in your business.

You may avoid a CRM software for a couple of employees when you start a business. However, to streamline the process and make the work efficient and fast – you will eventually need a CRM software.

But, what about the level of control (or security) in a CRM software? Do you want a transparent CRM software which you can take control of?

Well, that is when an open source CRM software comes into play. You can host it yourself, and you can customize it as per your requirements. You may also opt for the hosted version where you don’t have to manage it yourself.

Reviews

Today we are looking at the latest snapshot of ArcoLinux 19.07.11. We are looking at the main, edition, the XFCE release. It is based on Arch Linux, Linux Kernel 5.2, XFCE 4.12 and it uses about 600MB of ram when idling.

When I look at ArcoLinux, I can see just how much the developer loves this project and how much work he is putting into it. AcroLinux is clearly one of the best looking, and working great.

What am I doing with Tracker?

Filed under
GNOME

Some years ago I was asked to come up with some support for sandboxed apps wrt indexed data. This drummed up into Tracker 2.0 and domain ontologies, allowing those sandboxed apps to keep their own private data and collection of Tracker services to populate it.

Fast forward to today and… this is still largely unused, Tracker-using flatpak applications still whitelist org.freedesktop.Tracker, and are thus allowed to read and change content there. Despite I’ve been told it’s been mostly lack of time… I cannot blame them, domain ontologies offer the perfect isolation at the cost of the perfect duplication. It may do the job, but is far from optimal.

So I got asked again “we have a credible story for sandboxed tracker?”. One way or another, seems we don’t, back to the drawing board.

  • [GSoC – 4] Achieving consistency between SDDM and Plasma

    This blog post marks the landing of the initial implementation of theme syncing between SDDM and Plasma, which you may already have read about in Nate’s post.

    Those of you running master can test the feature out by going to the Advanced tab in the Login Screen (SDDM) config module.

  • Kate LSP Status – July 21

    The new LSP client by Mark Nauwelaerts keeps making nice progress.

    It will not be shipped with the KDE Applications 19.08 release, but in master it is now compiled & installed per default. You only need to activate it on the plugin configuration page in Kate’s settings dialog to be able to use it.

    For details how to build Kate master with it’s plugins, please take a look at this guide.

    If you want to start to hack on the plugin, you find it in the kate.git, addons/lspclient.

    Feel welcome to show up on kwrite-devel@kde.org and help out! All development discussions regarding this plugin happen there.

    If you are already familiar with Phabricator, post some patch directly at KDE’s Phabricator instance.

  • Second month progress

    So yes, we are gradually moving our way forward towards completely removing our dependence over KAuth. But there are some things which are yet to complete. To name one, I need to finish up QDbus communication from helper to application which sends dbus (Inter Process Communication) messages. Currently I had tried this in QDbus patch, but it is not yet fully complete. All this stuff is done by KAuth currently in master.

First Release Candidate of Linux 5.3

Filed under
Linux
  • Linux 5.3-rc1
    It's been two weeks, and the merge window is over, and Linux 5.3-rc1
    is tagged and pushed out.
    
    This is a pretty big release, judging by the commit count. Not the
    biggest ever (that honor still goes to 4.9-rc1, which was
    exceptionally big), and we've had a couple of comparable ones (4.12,
    4.15 and 4.19 were also big merge windows), but it's definitely up
    there.
    
    The merge window also started out pretty painfully, with me hitting a
    couple of bugs in the first couple of days. That's never a good sign,
    since I don't tend to do anything particularly odd, and if I hit bugs
    it means code wasn't tested well enough. In one case it was due to me
    using a simplified configuration that hadn't been tested, and caused
    an odd issue to show up - it happens. But in the other case, it really
    was code that was too recent and too rough and hadn't baked enough.
    The first got fixed, the second just got reverted.
    
    Anyway, despite the rocky start, and the big size, things mostly
    smoothed out towards the end of the merge window. And there's a lot to
    like in 5.3. Too much to do the shortlog with individual commits, of
    course, so appended is the usual "mergelog" of people I merged from
    and a one-liner very high-level "what got merged". For more detail,
    you should go check the git tree.
    
    As always: the people credited below are just the people I pull from,
    there's about 1600 individual developers (for 12500+ non-merge
    commits) in this merge window.
    
    Go test,

  • Linux 5.3-rc1 Debuts As "A Pretty Big Release"

    Just as expected, Linus Torvalds this afternoon issued the first release candidate of the forthcoming Linux 5.3 kernel.

    It's just not us that have been quite eager for Linux 5.3 and its changes. Torvalds acknowledged in the 5.3-rc1 announcement that this kernel is indeed a big one: "This is a pretty big release, judging by the commit count. Not the biggest ever (that honor still goes to 4.9-rc1, which was exceptionally big), and we've had a couple of comparable ones (4.12, 4.15 and 4.19 were also big merge windows), but it's definitely up there."

  • The New Features & Improvements Of The Linux 5.3 Kernel

    The Linux 5.3 kernel merge window is expected to close today so here is our usual recap of all the changes that made it into the mainline tree over the past two weeks. There is a lot of changes to be excited about from Radeon RX 5700 Navi support to various CPU improvements and ongoing performance work to supporting newer Apple MacBook laptops and Intel Speed Select Technology enablement.

HowTos
  • How to fix Ubuntu live USB not booting
  • How to Create a User Account Without useradd Command in Linux?
  • Container use cases explained in depth
  • Containerization and orchestration concepts explained
  • Set_env.py

    A good practice when writing complicated software is to put in lots of debugging code. This might be extra logging, or special modes that tweak the behavior to be more understandable, or switches to turn off some aspect of your test suite so you can focus on the part you care about at the moment.

    But how do you control that debugging code? Where are the on/off switches? You don’t want to clutter your real UI with controls. A convenient option is environment variables: you can access them simply in the code, your shell has ways to turn them on and off at a variety of scopes, and they are invisible to your users.

    Though if they are invisible to your users, they are also invisible to you! How do you remember what exotic options you’ve coded into your program, and how do you easily see what is set, and change what is set?

  • RPushbullet 0.3.2

    A new release 0.3.2 of the RPushbullet package is now on CRAN. RPushbullet is interfacing the neat Pushbullet service for inter-device messaging, communication, and more. It lets you easily send alerts like the one to the left to your browser, phone, tablet, … – or all at once.

    This is the first new release in almost 2 1/2 years, and it once again benefits greatly from contributed pull requests by Colin (twice !) and Chan-Yub – see below for details.

  • A Makefile for your Go project (2019)

    My most loathed feature of Go was the mandatory use of GOPATH: I do not want to put my own code next to its dependencies. I was not alone and people devised tools or crafted their own Makefile to avoid organizing their code around GOPATH.

  • Writing sustainable Python scripts

    Python is a great language to write a standalone script. Getting to the result can be a matter of a dozen to a few hundred lines of code and, moments later, you can forget about it and focus on your next task.

    Six months later, a co-worker asks you why the script fails and you don’t have a clue: no documentation, hard-coded parameters, nothing logged during the execution and no sensible tests to figure out what may go wrong.

    Turning a “quick-and-dirty” Python script into a sustainable version, which will be easy to use, understand and support by your co-workers and your future self, only takes some moderate effort.

The Status of Fractional Scaling (HiDPI) Between Windows & Linux

Filed under
GNU
Graphics/Benchmarks
Linux

There’s a special type of displays commonly called “HiDPI“, which means that the number of pixels in the screen is doubled (vertically and horizontally), making everything drawn on the screen look sharper and better. One of the most common examples of HiDPI are Apple’s Retina displays, which do come with their desktops and laptops.

However, one issue with HiDPI is that the default screen resolutions are too small to be displayed on them, so we need what’s called as “scaling”; Which is simply also doubling the drawn pixels from the OS side so that they can match that of the display. Otherwise, displaying a 400×400 program window on a 3840×2160 display will give a very horrible user experience, so the OS will need to scale that window (and everything) by a factor of 2x, to make it 800×800, which would make it better.

Fractional scaling is the process of doing the previous work, but by using fractional scaling numbers (E.g 1.25, 1.4, 1.75.. etc), so that they can be customized better according to the user’s setup and needs.

Now where’s the issue, you may ask? Windows operating system has been supporting such kind of displays natively for a very long time, but Linux distributions do lack a lot of things in this field. There are many drawbacks, issues and other things to consider. This article will take you in a tour about that.

Post-$34 billion acquisition by IBM, Red Hat bets big on India

Filed under
Red Hat

After the International Business Machines Corp. (IBM) completed the acquisition of Red Hat for $34 billion earlier this month, a top executive from the iconic software company with an open source development model has said that it was a "match made in heaven" that will help it accelerate growth globally, including in India.

In India, Red Hat, which specialises in Linux operating systems, has engineering facilities in Pune and Bengaluru.

[...]

Founded in 1993, Red Hat is credited for bringing open source -- including technologies like Linux, Kubernetes, Ansible, Java and Ceph, among others -- into the mainstream for the enterprises.

Today, Red Hat products and services are widely used by government agencies as well as emerging companies in technology, finance, healthcare, civil aviation and other industries.

Armonk, New York-headquartered IBM particularly hopes that Red Hat's open hybrid Cloud technologies would help it position itself as a leading hybrid Cloud provider.

"At the core of what we do is turning projects in the open source communities into products because at the end of the day, our customer is an enterprise software customer," Allessio said.

  • Clean out your fonts, people

    Thus, the number of fonts you have currently installed directly affects TenFourFox's performance, and TenFourFox is definitely not the only application that needs to know what fonts are installed. If you have a large (as in several hundred) number of font files and particularly if you are not using an SSD, you should strongly consider thinning them out or using some sort of font management system. Even simply disabling the fonts in Font Book will help, because under the hood this will move the font to a disabled location, and TenFourFox and other applications will then not have to track it further.

  • How open source and AI can take us to the Moon, Mars, and beyond

    Research institutions and national labs across the globe are pouring hundreds of thousands of research hours into every conceivable aspect of space science. And, overwhelmingly, the high performance computing (HPC) systems used for all research are running open source software.

    In fact, 100% of the current TOP500 supercomputers run on some form of Linux.

    Therefore, it’s likely that the future of space exploration will be built on the open source philosophy of knowledge sharing and collaboration among researchers and developers. Success will depend on the adoption of open technologies to stimulate collaboration among nations, as well as advances in the field of AI and machine learning.

    Although these are ambitious objectives that could take several years to fully implement, we are already seeing great progress: open source software is already running in space, AI and machine learning is used in spacecraft communications and navigation, and the number of commercial companies interested in the space economy is growing.

  • ElectrifAi launches AI industry’s first open source machine learning platform

    With the new platform, ElectrifAi’s data scientists – as well as those of its customers – can code and access data in any programming language. According to ElectrifAi, the incorporation of Docker Containers and Kubernetes enables the firm to build and deploy hybrid cloud enterprise solutions at scale.

  • The development of the open source platform – An industry perspective

    There has been much dialog, but not much action with regard to the evolution of retail trading platforms in recent years.

    For many brokerages, relying on the status quo which represents an unholy alliance between third party vendor MetaQuotes, thereby disabling a broker from owning its own client base or infrastructure and becoming subservient to an affiliate marketing platform rather than empowered by a multi-faceted trading platform, remains.

    FinanceFeeds has attended numerous meetings with brokerage senior executives across the globe, all of whom understand the value and importance of going down the multi-asset product expansion route, and almost all of whom understand the clear virtues of having a bespoke user interface which engenders a loyal customer base, enables brokers to own the entire intellectual property base of its business – which let’s face it is why entrepreneurs start businesses in the first place – and offer differentiating services to specific audiences.

    A simple glance at the continuity and geographic location of client bases of companies such as Hargreaves Lansdown or CMC Markets, and the absolute lack of reliance on affiliate networks is testimony to that.

    This week, Richard Goers, CEO of Australian professional trading platform development company ManagedLeverage spoke out about a continuing issue which is something that has been prominent in the viewpoint of FinanceFeeds for some years, that being the development of open source platforms.

  • How Suse is taking open source deeper into the enterprise

    The diversity in the open source software world can be a boon and a bane to wider adoption in the enterprise.

    After all, without the right knowhow, it can be hard to figure out how they are going to work together on existing infrastructure – and if the chosen projects will eventually survive.

    That’s where open source companies such as Suse step in. While smaller than US-based rival Red Hat, Suse has found its footing in identifying and supporting open source projects that help to run mission-critical enterprise workloads, improve developer productivity and solve business problems in industries such as retail.

  • SUSE joins iRODS Consortium

    iRODS is open source storage data management software for data discovery, workflow automation, secure collaboration, and data virtualization. By creating a unified namespace and a metadata catalog of all the data and users within a storage environment, the iRODS rule engine allows users to automate data management.

    [...]

    Alan Clark, SUSE CTO Office lead focused on Industry Initiatives and Emerging Standards and chairman of the OpenStack Foundation board of directors, said, “SUSE is excited to join the iRODS Consortium, lending our open source technical expertise to help advance the iRODS data management software. The integration with SUSE Enterprise Storage helps customers lower total cost of ownership, leveraging commodity hardware to support their iRODS-managed storage environments. As a leading provider of open source software, SUSE helps our customers leverage the latest open source technologies for application delivery and software-defined infrastructure. SUSE tests and hardens our solutions, ensuring they are enterprise ready and backed by our superior support experience.”

  • Why Open Source Matters For Chinese Tech Firms?

    As companies plow more and more investment into AI research, China has finally woken up to the realisation of open source and how it can shape the development of a field that’s becoming increasingly attractive. Over the last few years, open-source has become the foundation of innovation — and the major contributions come from tech giants like Facebook, Microsoft, Google, Uber and Amazon among others. In November 2015, Google made an unparalleled move by open-sourcing its software library — which now rivals Torch, Caffe and Theano.

    These are the open-source lessons that big Chinese companies seem to be learning fast. Traditionally, Chinese firms have trailed behind their US counterparts when it comes to the contributions from the US and Europe, but that’s changing now. Over a period of time, Chinese tech companies are trying to grow their influence in the open-source world by building a robust ecosystem. Not only that, they have learnt that open-sourcing tech can help attract great ML talent and increasingly it is also making good business sense. At a time when the AI tool stack is evolving, enterprises are rushing to grab a pie and provide a unified software and hardware technology stack. Internet and cloud Chinese tech giants have woken up to the promise of open source and AI-related datasets and models can serve the bigger business goals of the companies.

The move, in addition to other updates available now through YugaByte DB 1.3, allows users to more openly collaborate across what is now the world’s most powerful open source distributed SQL database.

  • SD Times Open-Source Project of the Week: YugaByte DB

    This week’s SD Times Open Source Project of the Week is the newly open-sourced YugaByte DB, which allows users to better collaborate on the distributed SQL database.

    The move to the open-source core project distributed under the Apache 2.0 license makes previously closed-sourced features such as distributed backups, data encryption and read replicas more accessible, according to the team. By doing this, YugaByte plans to break the boundaries between YugaByte’s Community and Enterprise editions.

    “YugaByte DB combines PostgreSQL’s language breadth with Oracle-like reliability, but on modern cloud infrastructure. With our licensing changes, we have removed every barrier that developers face in adopting a business-critical database and operations engineers face in running a fleet of database clusters, with extreme ease,” said Kannan Muthukkaruppan, co-founder and CEO of YugaByte.

Security Leftovers

Filed under
Security
  • Alas, Poor PGP

    The first is an assertion that email is inherently insecure and can’t be made secure. There are some fairly convincing arguments to be made on that score; as it currently stands, there is little ability to hide metadata from prying eyes. And any format that is capable of talking on the network — as HTML is — is just begging for vulnerabilities like EFAIL.

    But PGP isn’t used just for this. In fact, one could argue that sending a binary PGP message as an attachment gets around a lot of that email clunkiness — and would be right, at the expense of potentially more clunkiness (and forgetfulness).

    What about the web-of-trust issues? I’m in agreement. I have never really used WoT to authenticate a key, only in rare instances trusting an introducer I know personally and from personal experience understand how stringent they are in signing keys. But this is hardly a problem for PGP alone. Every encryption tool mentioned has the problem of validating keys. The author suggests Signal. Signal has some very strong encryption, but you have to have a phone number and a smartphone to use it. Signal’s strength when setting up a remote contact is as strong as SMS. Let that disheartening reality sink in for a bit. (A little social engineering could probably get many contacts to accept a hijacked SIM in Signal as well.)

    How about forward secrecy? This is protection against a private key that gets compromised in the future, because an ephemeral session key (or more than one) is negotiated on each communication, and the secret key is never stored. This is a great plan, but it really requires synchronous communication (or something approaching it) between the sender and the recipient. It can’t be used if I want to, for instance, burn a backup onto a Bluray and give it to a friend for offsite storage without giving the friend access to its contents. There are many, many situations where synchronous key negotiation is impossible, so although forward secrecy is great and a nice enhancement, we should assume it to be always applicable.

    [...]

    My current estimate is that there’s no magic solution right now. The Sequoia PGP folks seem to have a good thing going, as does Saltpack. Both projects are early in development, so as a privacy-concerned person, should you trust them more than GPG with appropriate options? That’s really hard to say.

  • Open source solutions in autonomous driving: safety is more than an afterthought [Ed: A lot less likely to contain back doors, unlike proprietary software where this has become rather 'standard' a 'feature']

    In the automotive industry, in-vehicle infotainment (IVI) systems were one of the early adopters of open source operating systems, namely Linux. Today’s innovation and success with IVIs can largely be attributed to this approach.

    Collaborative efforts such as the GENIVI Alliance and Automotive Grade Linux—where automakers, suppliers, and their competitors agree to share common elements of the IVI software stack—are enabling rapid development in this area.

    Part of the reason for setting up a foundation lies in the ethos of blockchain and other distributed ledger technology (DLT) systems: to offer decentralised platforms that anyone can use to store and transmit their data – a so-called “open source” model.

Have a great week!

  • Full Circle Magazine: Full Circle Weekly News #140
  • Christopher Allan Webber: ActivityPub Conf 2019

    That's right! We're hosting the first ever ActivityPub Conf. It's immediately following Rebooting Web of Trust in Prague. There's no admission fee to attend. (Relatedly, the conference is kind of being done on the cheap, because it is being funded by organizers who are themselves barely funded.) The venue, however, is quite cool: it's at the DOX Centre for Contemporary Art, which is itself exploring the ways the digital world is affecting our lives. If you plan on attending (and maybe also speaking), you should get in your application soon (see the flier for details). We've never done one of these, and we have no idea what the response will be like, so this is going to be a smaller gathering (about 40 people). In some ways, it will be somewhere between a conference and a gathering of people-who-are-interested-in-activitypub. As said in the flier, by attending, you are agreeing to the code of conduct, so be sure to read that.

Sysadmin Appreciation Day, IBM and Fedora

  • Gift ideas for Sysadmin Appreciation Day

    Sysadmin Appreciation Day is coming up this Friday, July 26. To help honor sysadmins everywhere, we want you to share your best gift ideas. What would be the best way a team member or customer could show their appreciation for you? As a sysadmin, what was the best gift you've ever received? We asked our writers the same question, and here are their answers: "Whilst working in the Ubuntu community on Edubuntu, I took it upon myself to develop the startup/shutdown sound scheme, which became the default in Ubuntu for, from what I can understand, the next decade. Whilst people had a love-hate relationship with my sound scheme, and rightly so, I had a love-hate relationship with my sound card during the development. At the time I had recorded all my sound samples using one sample rate, but my new sound card, as my motherboard had exploded a few days earlier, did not support it. I had two choices, resample all my samples (which I didn't really want to do) or buy a new sound card.

  • Red Hat OpenStack Platform with Red Hat Ceph Storage: Radosbench baseline performance evaluation

    Red Hat Ceph Storage is popular storage for Red Hat OpenStack Platform. Customers around the world run their hyperscale, production workloads on Red Hat Ceph Storage and Red Hat OpenStack Platform. This is driven by the high level of integration between Ceph storage and OpenStack private cloud platforms. With each release of both platforms, the level of integration has grown and performance and automation has increased. As the customer's storage and compute needs for footprints have grown, we have seen more interest towards running compute and storage as one unit and providing a hyperconverged infrastructure (HCI) layer based on OpenStack and Ceph. [...] Continuing the benchmarking series, in the next post you’ll learn performance insights of running multi-instance MySQL database on Red Hat OpenStack Platform and Red Hat Ceph Storage across decoupled and hyperconverged architectures. We’ll also compare results from a near-equal environment backed by all-flash cluster nodes.

  • The State of Java in Flathub

    For maintainers of Java-based applications in Flathub, it's worth noting that even if you consume the Latest OpenJDK extension in your application, users will not be broken by major updates because OpenJDK is bundled into your Flatpak. The implication of this for users is that they won't see updates to their Java version until the application maintainer rebuilds the application in Flathub. If you maintain a Java-based Flatpak application on Flathub, you can consume the latest version of your chosen OpenJDK stream (either LTS or Latest) simply by rebuilding; the latest version of that OpenJDK steam will be pulled in automatically.

  • Fedora Magazine: Contribute at the Fedora Test Week for kernel 5.2

  • Candy Tsai: Outreachy Week 6 – Week 7: Getting Code Merge

    You can’t overhear what others are doing or learn something about your colleagues through gossip over lunch break when working remotely. So after being stuck for quite a bit, terceiro suggested that we try pair programming. After our first remote pair programming session, I think there should be no difference in pair programming in person. We shared the same terminal, looked at the same code and discussed just like people standing side by side. Through our pair programming session, I found out that I had a bad habit. I didn’t run tests on my code that often, so when I had failing tests that didn’t fail before, I spent more time debugging than I should have. Pair programming gave insight to how others work and I think little improvements go a long way.

  • about your wiki page on I/O schedulers and BFQ
    Hi,
    this is basically to report outdated statements in your wiki page on
    I/O schedulers [1].
    
    The main problematic statement is that BFQ "...  is not ideal for
    devices with slow CPUs or high throughput I/O devices" because too
    heavy.  BFQ is definitely more sophisticated than any of the other I/O
    schedulers.  We have designed it that way to provide an incomparably
    better service quality, at a very low overhead.  As reported in [2],
    the execution time of BFQ on an old laptop CPU is 0.6 us per I/O
    event, against 0.2 us for mq-deadline (which is the lightest Linux I/O
    scheduler).
    
    To put these figures into context, BFQ proved to be so good for
    "devices with slow CPUs" that, e.g., Chromium OS migrated to BFQ a few
    months ago.  In particular, Google crew got convinced by a demo [3] I
    made for them, on one of the cheapest and slowest Chromebook on the
    market.  In the demo, a fast download is performed.  Without BFQ, the
    download makes the device completely unresponsive.  With BFQ, the
    device remains as responsive as if it was totally idle.
    
    As for the other part of the statement, "...  not ideal for ...  high
    throughput I/O devices", a few days ago I ran benchmarks (on Ubuntu)
    also with one of the fastest consumer-grade NVMe SSDs: a Samsung SSD
    970 PRO.  Results [4] can be summarized as follows.  Throughput with
    BFQ is about the same as with the other I/O schedulers (it couldn't be
    higher, because this kind of drives just wants the scheduler to stay
    as aside as possible, when it comes to throughput).  But, in the
    presence of writes as background workload, start-up times with BFQ are
    at least 16 times as low as with the other I/O schedulers.  In
    absolute terms, gnome-terminal starts in ~1.8 seconds with BFQ, while
    it takes at least 28.7 (!) seconds with the other I/O schedulers.
    Finally, only with BFQ, no frame gets lost in video-playing
    benchmarks.
    
    BFQ then provides other important benefits, such as from 5x to 10X
    throughput boost in multi-client server workloads [5].
    
    So, is there any chance that the outdated/wrong information on your
    wiki page [1] gets updated somehow?  If I may, I'd be glad to update
    it myself, after providing you with all the results you may ask.
    
    In addition, why doesn't Ubuntu too consider switching to BFQ as
    default I/O scheduler, for all drives that BFQ supports (namely all
    drives with a maximum speed not above ~500 KIOPS)?
    
    Looking forward to your feedback,
    Paolo
    
    
  • Should Ubuntu Use The BFQ I/O Scheduler?

    The BFQ I/O scheduler is working out fairly well these days as shown in our benchmarks. The Budget Fair Queueing scheduler supports both throughput and low-latency modes while working particularly well for consumer-grade hardware. Should the Ubuntu desktop be using BFQ by default? [...] But in addition to wanting to correct that Wiki information, Paolo pops the question of why doesn't Ubuntu switch to BFQ as the default I/O scheduler for supported drives. Though as of yet, no Ubuntu kernel developers have yet commented on the prospect of switching to BFQ.
