Where do you turn when you have a fleet of public workstations to manage? If you’re the Czech National Library of Technology (NTK), you turn to Fedora. Located in Prague, the NTK is the Czech Republic’s largest science and technology library. As part of its public service mission, the NTK provides 150 workstations for public use.

In 2018, the NTK moved these workstations from Microsoft Windows to Fedora. In the press release announcing this change, Director Martin Svoboda said switching to Fedora will “reduce operating system support costs by about two-thirds.” The choice to use Fedora was easy, according to NTK Linux Engineer Miroslav Brabenec. “Our entire Linux infrastructure runs on RHEL or CentOS. So for desktop systems, Fedora was the obvious choice,” he told Fedora Magazine.

  • CERN ends trial of Facebook Workplace

    New changes to the status of CERN’s Workplace account prevent the Organization from continuing on the platform. CERN’s presence on Workplace will end on 31 January 2020. In October 2016, Facebook made Workplace available to any company or organisation.

  • CERN Replacing Facebook Workplace With A Set Of Open-Source Software Alternatives

    Facebook Workplace is Facebook's corporate-focused product for internal real-time communication and related communication needs within organizations. CERN had been making use of Facebook Workplace and in addition to data privacy concerns, they were recently confronted with either paying Facebook or losing administrative rights, no more single sign-on access, and Facebook having access to their internal data. But now they have assembled their own set of software packages to fill the void by abandoning Facebook Workplace.

Sci/Tech

There are many online sources available that provide data sets for educational and study purposes. They cover many different areas (physics, statistics, medicine, etc.) and many tools and frameworks provide wrappers for them and allow you to easily play around with the data sets. In many cases, the technical tasks of fetching the data from the server, parsing it and installing it are completely transparent for users.

We recently added a similar functionality to LabPlot and we plan to release this new feature as part of the upcoming 2.8 version. The initial implementation for this was done by Ferencz Kovács during Google Summer of Code 2019.

Stretch Controls

Hy Murveit implemented adjustable and fast stretch controls for mono and color images within the FITS Viewer. These allow fine changes in Shadows, Midtones, and Highlights clipping even for high resolution astro-photos.

Adjusting the controls do not change the underlying data, only the previewed image. After any stretch adjustment is made, the user can always revert to the automatic stretching again by clicking on the small wizard icon at the bottom right corner of the controls panel.

Happy 50th Birthday To All You Epoch Birthers

Sci/Tech

Good morning everyone, and what a lovely start to the new year it is, because it’s your birthday! Happy birthday, it’s your 50th! What’s that you say, you aren’t 50 today? (Looks…) That’s what all these internet databases say, because you’ve spent the last decade or so putting 1970-01-01 as your birth date into every online form that doesn’t really need to know it!

It’s been a staple for a subset of our community for years, to put the UNIX epoch, January 1st 1970, into web forms as a birth date. There are even rumours that some sites now won’t accept that date as a birthday, such is the volume of false entries they have with that date. It’s worth taking a minute though to consider UNIX time, some of its history and how its storage has changed over the years.

CERN to switch to Kopano mail server for its 40,000 users

Filed under
OSS
Sci/Tech

In June the IT trade press reported widely on CERN's Microsoft Alternatives (MALT) project. “It started off as a very unfortunate situation with license costs increasing, but has turned into a great opportunity to review the way we do things in order to move towards open solutions,” Tenaglia told the European Commission’s Open Source Observatory.

The first tangible outcome of this is a switch to the Kopano mail server. CERN is currently evaluating Kopano, aiming in due course to support 40,000 users and some 60 terabytes of mail data. CERN is running an on-premises pilot of the same size as its production server, which uses Microsoft Exchange. The research organisation, based in Meyrin, Switzerland, has a support contract with Kopano, the Dutch/German software company that is developing the eponymous mail server. “Kopano offers support for their 100% open source software. That sets it apart from business that offer support for premium features built onto their basic open source product,” Tanaglia says.

  • An Open Source Toolbox For Studying The Earth

    Fully understanding the planet’s complex ecosystem takes data, and lots of it. Unfortunately, the ability to collect detailed environmental data on a large scale with any sort of accuracy has traditionally been something that only the government or well-funded institutions have been capable of. Building and deploying the sensors necessary to cover large areas or remote locations simply wasn’t something the individual could realistically do.

    But by leveraging modular hardware and open source software, the FieldKit from [Conservify] hopes to even the scales a bit. With an array of standardized sensors and easy to use software tools for collating and visualizing collected data, the project aims to empower independent environmental monitoring systems that can scale from a handful of nodes up to several hundred.

  • The Early History of Usenet, Part II: Hardware and Economics

    There was a planning meeting for what became Usenet at Duke CS. We knew three things, and three things only: we wanted something that could be used locally for administrative messages, we wanted a networked system, and we would use uucp for intersite communication. This last decision was more or less by default: there were no other possibilities available to us or to most other sites that ran standard Unix. Furthermore, all you needed to run uucp was a single dial-up modem port. (I do not remember who had the initial idea for a networked system, but I think it was Tom Truscott and the late Jim Ellis, both grad students at Duke.)

    There was a problem with this last option, though: who would do the dialing? The problems were both economic and technical-economic. The latter issue was rooted in the regulatory climate of the time: hardwired modems were quite unusual, and ones that could automatically dial were all but non-existent. (The famous Hayes Smartmodem was still a few years in the future.) The official solution was a leased Bell 801 autodialer and a DEC DN11 peripheral as the interface between the computer and the Bell 801. This was a non-starter for a skunkworks project; it was hard enough to manage one-time purchases like a modem or a DN11, but getting faculty to pay monthly lease costs for the autodialer just wasn't going to happen. Fortunately, Tom and Jim had already solved that problem.

  • UNIX Version 0, Running On A PDP-7, In 2019

    WIth the 50th birthday of the UNIX operating system being in the news of late, there has been a bit of a spotlight shone upon its earliest origins. At the Living Computers museum in Seattle though they’ve gone well beyond a bit of historical inquiry though, because they’ve had UNIX (or should we in this context say unix instead?) version 0 running on a DEC PDP-7 minicomputer. This primordial version on the original hardware is all the more remarkable because unlike its younger siblings very few PDP-7s have survived.

    The machine running UNIX version 0 belongs to [Fred Yearian], a former Boeing engineer who bought his machine from the company’s surplus channel at the end of the 1970s. He restored it to working order and it sat in his basement for decades, while the vintage computing world labored under the impression that including the museum’s existing machine only four had survived — of which only one worked. [Fred’s] unexpected appearance with a potentially working fifth machine, therefore, came as something of a surprise.

  • New, open-source database improves genomics research collaboration

    Sharing datasets that reveal the function of genomic variants in health and disease has become easier, with the launch of a new, open-source database developed by Australian and North American researchers.

    The MaveDB database is a repository for data from experiments - called multiplex assays of variant effect (MAVEs) - that systematically measure the impact of thousands of individual sequence variants on a gene's function.

  • Open-source database enhances genomics research collaboration

    An open-source database of genomic variants in health and disease has been developed by Australian and North American researchers to simplify the sharing of this information between academics.

    The MaveDB database stores data from multiplex assays of variant effect (MAVE) experiments, which systematically measure the impact of thousands of individual sequence variants on a gene’s function. It was developed by researchers from the Walter and Eliza Hall Institute of Medical Research in Melbourne, Australia, as well as the University of Washington in the US and the University of Toronto in Canada.

  • Open-source Database Enhances Genomics Research Collaboration

    The MaveDB database is a repository for data from experiments – called multiplex assays of variant effect (MAVEs) – that systematically measure the impact of thousands of individual sequence variants on a gene’s function. These experiments can provide valuable information about how proteins produced by that gene function, how variants in that gene may contribute to disease, and how to engineer synthetic versions of naturally occurring proteins that are more effective than the original protein.

    MaveDB is the first publicly accessible database for this data. Its development was led by Alan Rubin from the Walter and Eliza Hall Institute, Australia, Associate Professor Douglas Fowler from the University of Washington, US, and Professor Frederick Roth from the University of Toronto, Canada.

Antitrust Laws and Open Collaboration

If you participate in standards development organizations, open source foundations, trade associations, or the like (Organizations), you already know that you’re required to comply with antitrust laws. The risks of noncompliance are not theoretical – violations can result in severe criminal and civil penalties, both for your organization and the individuals involved. The U.S. Department of Justice (DOJ) has in fact opened investigations into several standards organizations in recent years. Maybe you’ve had a training session at your company, or at least are aware that there’s an antitrust policy you’re supposed to read and comply with. But what if you’re a working group chair, or even an executive director, and therefore responsible for actually making sure nothing happens that’s not supposed to? Beyond paying attention, posting or reviewing an antitrust statement at meetings, and perhaps calling your attorney when member discussions drift into grey zones, what do you actually do to keep antitrust risk in check? Well, the good news is that regulators recognize that standards and other collaboration deliverables are good for consumers. The challenge is knowing where the boundaries of appropriate conduct can be found, whether you’re hosting, leading or just participating in activity involving competitors. Once you know the rules, you can forge ahead, expecting to navigate those risks, and knowing the benefits of collaboration can be powerful and procompetitive. We don’t often get glimpses into the specific criteria regulators use to evaluate potential antitrust violations, particularly as applicable to collaborative organizations. But when we do, it can help consortia and other collaborative foundations focus their efforts and take concrete steps to ensure compliance. In July 2019, the DOJ Antitrust Division (Division) provided a new glimpse, in its Evaluation of Corporate Compliance Programs in Criminal Antitrust Investigations (Guidance). Although the Guidance is specifically intended to assist Division prosecutors evaluating corporate compliance programs when charging and sentencing, it provides valuable insights for building or improving an Organization’s antitrust compliance program (Program). At a high level, the Guidance suggests that an effective Program will be one that is well designed, is applied earnestly and in good faith by management, and includes adequate procedures to maximize effectiveness through efficiency, leadership, training, education, information and due diligence. This is important because organizations that detect violations and self-report to the Division’s Corporate Leniency program may receive credit (e.g. lower charges or penalties) for having an effective antitrust compliance program in place.

  • Certificate validity and a y2k20 bug

    One of the standard fields of an SSL certificate is the validity period. This field includes notBefore and notAfter dates which, according to RFC5280 section 4.1.2.5, indicates the interval "during which the CA warrants that it will maintain information about the status of the certificate" This is one of the fields that should be inspected when accepting new or unknown certificates. When creating certificates, there are a number of theories on how long to set that period of validity. A short period reduces risk if a private key is compromised. The certificate expires soon after and can no longer be used. On the other hand, if the keys are well protected, then there is a need to regularly renew those short-lived certificates.

  • NG Firewall 15.0 is here with better protection for SMB assets

    Here comes the release of NG Firewall 15.0 by Untangle with the creators claiming top-notch security for SMB assets. Let’s thoroughly discuss the latest NG Firewall update. With that being said, it only makes sense to first introduce this software to the readers who aren’t familiar with it. As the name ‘NG Firewall’ suggests, it is indeed a firewall but a very powerful one. It is a Debian-based and network gateway designed for small to medium-sized enterprises. If you want to be up-to-date with the latest firewall technology, your best bet would be to opt for this third-generation firewall. Another factor that distinguishes the NG Firewall from other such products in the market is that it combines network device filtering functions and traditional firewall technology.
