Earlier this year, I have suggested together with other colleagues to the Icelandic government to use open-source software in order to save money. While we mentioned there already the opportunity to gain digital sovereignty, this has became even more important with the new administration in the U.S., i.e. being dependent on Microsoft or any other US software provider can be dangerous, because a "kill switch" could lead to making US software stop working and loosing access to your data that is stored in the cloud of an US company.
The Dutch parliament just approved a series of motions calling on the Dutch government to reduce dependence on U.S. software companies.

Also, if you check the accesses to the web page of european-alternatives.eu you see that the interest European alternatives for digital service and products is rapidly increasing since mid of January 2025, i.e. when the new US administration came into office.

Currently, the Icelandic government is drafting a bill on the future IT system for the Icelandic administration:

• A draft of a new bill has been made. While the 9 articles of the bill itself are very abstract, the justification that follows towards the end is more interesting to read.
• The first reading was held at the parliament. While Microsoft has been mentioned a couple of times, also Open-Source was mentioned once.

The question is whether a system like Stafrænt Ísland ("Digital Iceland") is created where Icelandic companies win tenders offered by the state and then develop software for the island.is portal (that can be used to access digital government services) (and the developed software is even made available as open-source) or whether one gigantic Microsoft solution is introduced.

In fact, other states are already working on digital sovereignty, for example the German Zentrum Digitale Souveränität, or short: ZenDis, that is working on OpenDesk which is an open-source solution intended for governments and other public institutions as alternative to Microsoft services that are currently used. Therefore, it would be exciting to see the Icelandic government offering tenders for integrating such software into the Icelandic government IT landscape and have then Iceland teams win these tenders. By this, digital sovereignty is achieved and Icelandic tax money stays in Iceland instead of feeding the big US tech companies and expertise is created and stays in Iceland.

I did not find that draft bill number 141 in the comment system of the parliament (umsagnagátt), but the above justification refers to comments that have been made earlier, so maybe this does not even go into the comment process again? In any case, it will be important to follow up on that.

The EU's Digital Europe Programme (DEP) is fostering digital transformation and therefore co-funding projects that improve cybersecurity, artificial intelligence, high-performance computing and other aspects of digital transformation.

We have already established in 2022 Eyvör – the National Cybersecurity Coordination Centre of Iceland (NCC-IS) that received co-funding from the European Cybersecurity Competence Centre (ECCC) for the period 10/2023-9/2025.

Now, we just got the notification that we will receive two further years of co-funding from the the ECCC/EU based on the call Deploying The Network of National Coordination Centres with Member States (DIGITAL-ECCC-2024-DEPLOY-NCC-06-MS-COORDINATION).

The core tasks of the follow-up Eyvör NCC-IS are:

• Acting as contact points at the national level for the Cybersecurity Competence Community to support the ECCC in achieving its objectives and missions;
• Providing expertise and actively contributing to the strategic tasks of the ECCC, taking into account relevant national and regional challenges for cybersecurity in different sectors;
• Promoting, encouraging and facilitating the participation of civil society, industry in particular start-ups and SMEs, academic and research communities and other actors at Member State level in cross-border projects and cybersecurity actions funded through all relevant Union programmes;
• Providing technical assistance to stakeholders by supporting the stakeholders in their application phase for projects managed by the ECCC, and in full compliance with the rules of sound financial management, especially on conflict of interests. This should be done in close coordination with relevant NCPs set up by Member States;
• Seeking to establish synergies with relevant activities at national, regional and local levels, such as addressing cybersecurity in national policies on research, development and innovation in the area of, and in particular in those policies stated in the national cybersecurity strategies;
• Where relevant, implementing specific actions for which grants have been awarded by the ECCC, including through provision of financial support to third parties, i.e. Evyör NCC-IS providing via Rannís funding to Icelandic companies to improve their cybersecurity. The funding should foremost facilitate the adoption and widespread use of state-of-the-art cybersecurity solutions. This should equip organisations with the latest and most effective tools and strategies available for cybersecurity, fortifying their overall cybersecurity capabilities, and helping them to become more resilient and better prepared to face the evolving challenges posed by cyber threats in the digital age.
• Promoting and disseminating the relevant outcomes of the work of the Network and the ECCC at national, regional or local level;
• Assessing requests for becoming part of the Cybersecurity Competence Community by entities established in the same Member State as the NCC;
• Advocating and promoting involvement by relevant entities in the activities arising from the ECCC, the Network of National Coordination Centres, and the Cybersecurity Competence Community, and monitoring, as appropriate, the level of engagement with actions awarded for cybersecurity research, developments and deployments.

To prevent any misunderstandings: Eyvör NCC-IS will not take over the job of CERT-IS (or any other party) nor is Eyvör NCC-IS a Security Operation Center (SOC). Eyvör NCC-IS is rather an add-on to existing activities in order to raise awareness, co-ordinate actions, and improve education and research related to Cybersecurity on national and European level.

Eyvör – the National Cybersecurity Coordination Centre of Iceland (NCC-IS) is co-funded by the ECCC/EU.

With larger screens, tiling windows become an issue. While there are special tiling window managers, KDE/Plasma has built-in tiling:

• System Settings -> Workspace Behaviour -> Screen Edges: enable Tile: Windows dragged to left or right edge: now you can drag windows to left or right edge and it gets tiled horizontally by half of the screen. Depending on the percentage at Trigger quarter tiling in: it depends on whether you drag the window to the upper or lower percentage of the screen to have the window vertically tiled by half of the screen. If you rather drag the window to the left or right centre of the screen, then the window will be only horizontally tiled but get full screen height.
• System Settings -> Workspace Behaviour -> Screen Edges: enable Maximize: Windows dragged to the top edge: now you can drag windows to the top edge to maximize them.
• To get horizontal tiling into three parts, you can hold the shift key while moving a window.
• Unfortunately, there are no mouse gestures to tile a window vertically but have them horizontally full screen size. But there are keyboard combinations: super key (typically: the Windows key) and cursor keys tile the window by half of the screen size in the respective cursor key direction.

The deadline (for students from Iceland) for applying for our B.Sc. programmes in Computer Science and Software Engineering is 5. June for the autumn semester that starts end of August. As I was involved in updating our programmes, I can assure you that you will receive up-to-date education and can really recommend studying with us.

It was just recently in the news that Iceland will need 9000 specialists within next 5 years -- you will be one of them if you studied Computer Science and Software Engineering at University of Iceland.

If you want to learn more about Software Engineering, I have a blog post Why you should study Software Engineering / Af hverju hugbúnaðarverkfræði and a distinction of Software Engineering versus Programming.

The Frostbyte lab is the joint cybersecurity lab of the security researchers and teachers at University of Iceland and Reykjavik University. It is co-funded by the Icelandic government and the EU/ECCC. The official opening to experts is on Friday, 7 February 2025, and to the general public on Saturday, 8 February 2025, 11:00-16:00, in Harpa at the IT fair UT messan. Both University of Iceland and Reykjavik University have at the exhibition day for the public a booth on the 2nd floor of Harpa where you can learn more about the lab. The lab is open to interested parties for their cybersecurity research: please contact people at Frostbyte lab if you have a cybersecurity use case. For example, we offer to do a security scan if your organisation that has computers facing the internet.

From the lab opening to experts on 7.2.2025.

From the lab opening to the general public on 8.2.2025.

Gagnabær ("Datatown") digital twin that visualises cyber attacks in Iceland: each time our server gets attacked, a light goes off.

Presentation slides

To play them:

1. Open link in browser;
2. Slides should automatically advance every 20 seconds (possible to adjust that value via the delayms parameter of the URL) -- if they do not advance: reload page via F5 key;
3. Switch to fullscreen mode:
• In Chrome: F5 (=reload to start), followed by F11 (=fullscreen);
• In Firefox: do not use F11 key (would stop auto advance), but rather 'hamburger' menu and there, in the Zoom entry line on the very right, click the fullscreen icon.

This event is in the context of our cybersecurity activities and the ECCC/EU co-funded projects ICEDEF – Defend Iceland and Eyvör – the National Cybersecurity Coordination Centre of Iceland (NCC-IS).

While Eneloop batteries are the best NiMH AA and AAA batteries that you can get, they have only 1.2 V and some devices need in fact the full 1.5 V of a normal AA battery (e.g. 3.3 V logic that assumes 2 x 1.5 V AA batteries). Li-ion batteries can disguise as 1.5 V AA batteries by using a voltage regulator that step down the Li-ion voltage to 1.5 V. Newer variants have even a USB charging port built in, so that you can charge them without a NiMH charger, but just with any USB power source.

Such Li-ion-based AA batteries typically have two disadvantages:

• The keep the 1.5 V as long as possible and when they are empty, they simply shut down: a device that assumes a normal 1.5 AA battery uses however the voltage drop that a AA 1.5 V battery has when it gets drained to display in advance whether the battery needs to be replaced. This will not work with the Li-ion-based batteries.
• The Li-ion-based batteries can be deep discharged: while they have a protection circuit that switches them off, they recover after some time and the protection circuit enabled the battery again which drains them further and so on.

According to tests (in German), the Keeppower P1450TC (ca. 6.45 EUR with USB C charging port) seems currently to be the only exception that does not have that disadvantage. (However, it starts to drop the voltage somewhat too early so that devices that really need 1.5 V switch off far too early. Would be interesting to see whether future brings even better alternatives).

Have Ghostscript installed, and then

gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/ebook -dNOPAUSE -dQUIET -dBATCH -sOutputFile=compressed_output.pdf input.pdf

The possible -dPDFSETTINGS are:

• /screen selects low-resolution output similar to the Acrobat Distiller "Screen Optimized" setting.
• /ebook selects medium-resolution output similar to the Acrobat Distiller "eBook" setting.
• /printer selects output similar to the Acrobat Distiller "Print Optimized" setting.
• /prepress selects output similar to Acrobat Distiller "Prepress Optimized" setting.
• /default selects output intended to be useful across a wide variety of uses, possibly at the expense of a larger output file.

While there are online services that can compress such documents, these are of course not suitable for privacy-sensitive documents and may in addition insert malware into the created documents.

Marcel Aach defended yesterday successfully his PhD thesis on Parallel and Scalable Hyperparameter Optimization for Distributed Deep Learning Methods on High-Performance Computing Systems.

Marcel's research was rooted in the CoE RAISE project. This PhD is an example of the collaboration between the Faculty of Industrial Engineering, Mechanical Engineering and Computer Science and Jülich Supercomputing Centre (JSC).

University of Iceland, Defend Iceland, Eyvör National Cybersecurity Coordination Centre Iceland (NCC-IS) will have a booth at the public visitor day at at UT messan 2025, the largest IT fair in Iceland. The visitor day is Saturday, 8 February 2025, 11:00-16:00, in Harpa.

We will showcase our cybersecurity lab, i.e. a computer server environment that allows to create virtualised environments to practise cybersecurity activities.

Furthermore, we will have a LEGO model of critical infrastructure in Iceland that show visually when services (that could be a service of a critical infrastructure) get hacked.

In addition, you can try to beat an AI in classification of remote sensing images.

This event is in the context of our cybersecurity activities and the ECCC/EU co-funded projects ICEDEF – Defend Iceland and Eyvör – the National Cybersecurity Coordination Centre of Iceland (NCC-IS).
