I'm Open Sourcing the Have I Been Pwned Code Base
- Open sourcing the HIBP code base gives me the opportunity to address that original problem I set out to solve with the M&A process: finding other people that can help sustain the project.
- People who live and breathe open source, people who understand .NET and Azure inside and out, people who know HIBP well and above all, people I trust to expose my own shortcomings so that they can help me make this thing more sustainable.
- Let me be clear: I don't have a timeline for each step along the way yet as HIBP remains something I do in my spare time and I've always got a bunch of other stuff on my plate, but the process has already begun and I'll be sharing more on that as soon as I can.
What Latvia Found in the KGB Archives
- A few weeks ago, just before the dawn of the new year, I typed my Latvian national identification number into a crisp online database and watched as an index of more than 4,000 crumbling, yellowed index cards appeared on my screen.
- Finally, in 2014, with a new president in office, parliament passed a measure authorizing the publication of the “Cheka bags”—only after a scientific commission completed a thorough study of their content, but no later than May 2018.
- The “Cheka bags” files provide a window into the workings of the Soviet security state, but not the “whole picture.” The 4,000 or so cards represent a fraction of the more than 24,000 KGB agents recruited in Latvia between 1953 and 1991.
Uber picks up Autocab to push into places its own app doesn't go
- Uber has bought UK based Autocab, which sells SaaS to the taxi and private hire vehicle industry, with the aim of expanding the utility of its own platform by linking users who open its app in places where it doesn’t offer trips to local providers who do.
- We’ve asked whether it will be closing a marketplace service which connects local taxi firms with trip bookers in any locations as a result of the Uber acquisition.
- Uber’s spokeswoman said it plans to support Autocab’s expansion of SaaS and iGo internationally — suggesting the tech giant hopes to be able to integrate the marketplace across its own global footprint in order to be able to offer users a less patchy service.
- It will remain independent with its own board after the acquisition, per the pair’s press release — retaining its focus on serving the taxi and private hire vehicle industry globally.
Leveraging Machine Learning to Fuel New Discoveries with the ArXiv Dataset
- To help make the arXiv more accessible, we present a free, open pipeline on Kaggle to the machine-readable arXiv dataset: a repository of 1.7 million articles, with relevant features such as article titles, authors, categories, abstracts, full text PDFs, and more.
- Our hope is to empower new use cases that can lead to the exploration of richer machine learning techniques that combine multi-modal features towards applications like trend analysis, paper recommender engines, category prediction, co-citation networks, knowledge graph construction, and semantic search interfaces.
- An example of such a semantic search application built on top of a specific corpus would be Google’s COVID-19 Research Explorer, a tool that helps researchers pore through the CORD-19 dataset – a repository of 190,000+ science articles on COVID-19.
New lockdown confusion splinters Team Australia
- The Team Australia unity between government and business during the coronavirus crisis is now splintering, with business left in the dark about the new Lockdown 3.0 rules in Victoria.
- The Team Australia unity between government and business that has saved both lives and livelihoods during the coronavirus crisis is now splintering amid a torrent of complaints from business leaders and business bodies about the state of confusion into which Victoria's virus response has descended.
- With another 725 cases in the state yesterday, Premier Daniel Andrews had little choice but to move to the stage four health restrictions which threatens to send the national economic recovery into reverse and, as S&P warned yesterday, downgrade the state’s AAA credit rating.
- The business confusion over the stage four lockdown due to start today follows bungles with hotel quarantine and contact testing and tracing that let the virus escape and run wild again.
The best Parts of Visual Studio Code are proprietary
- It makes me uneasy to accept VS Code as an "open" project in any wider meaning of the word when compelling features are legally locked to only work inside the family of Visual Studio products.
- There is an open source alternative called Open VSX, but since it isn't the canonical one it is missing a bunch of extensions and the big Liveshare and Remote ones are still not allowed.
- Visual Studio Code is marketed with LiveShare and Remote as powerful extensions.
- It is easy to use the editor, install the extensions and be under the impression that you are using an open source software suite where Microsoft simply hosts the peering service for identifying and connecting you and your collaborator.
- The extensions are not open source projects as far as I can find and they are licensed during distribution in a way that disallows using them with anything but Visual Studio products.
New official DIN standard for Open Source Hardware in Germany (German)
- Ein Indiz für den wachsenden Zuspruch zu Open-Source-Ideen auch im Hardware-Bereich ist ein kürzlich verabschiedeter Standard des Deutschen Instituts für Normung (DIN) mit dem sperrigen Titel „DIN SPEC 3105“.
- Wie es dazu gekommen ist und warum auch der Standard selbst offener als andere DIN-Standards ist, erklärt Open-Hardware-Aktivist Martin Häuer im Interview.
- Martin Häuer: Im Fall von Software ist die Sache einigermaßen einfach: Source Code unter freier/offener Lizenz veröffentlichen und fertig.
- Martin Häuer: In öffentlich geförderten Forschungsprojekten kann ab sofort die Dokumentation eines Prototypen „nach DIN SPEC 3105-1“ als klar definiertes Forschungsergebnis angeführt werden, was die Akquise von Geldern für diesen Zweck erleichtert.
- Martin Häuer: Dieser Open-Source-Standard kann in jeder erdenklichen Weise frei verwertet werden, sofern der Lizenzgeber (DIN e.V.) genannt und das Derivat ebenfalls unter offener Lizenz freigegeben wird.
- Auch die Referenzierung auf andere Standards gestaltete sich mitunter schwierig, da Open-Source-Prinzipien dort noch keine Erwähnung fanden und diese Standards daher nur bedingt für uns passten.

Web apps aren't tech. They're “tech”
- I do hear sometimes from programmers who are kind of sad that they don't have the opportunity to write game engines from scratch like I did and have it matter or make an impact...
- I was definitely a programmer who felt like I'd missed a golden era of opportunity.
- First journalists, and now many of us are referring to everything from web SaaS apps to mobile productivity apps as "tech".
- To an ambitious engineer looking for a market opportunity in "tech", things look crowded.
- Advances in programming languages, frameworks, open source collaboration, dev ops, visual site-building tools and more have made it dramatically easier to create both web apps and mobile apps than it was a decade ago.
- But web apps aren't tech.
- Even he felt like it was "too late" because of missing all the opportunities of the 80s.
