From The “Too Much Time On Their Hands” Department ...

... comes this pure-CSS recreation <https://www.theregister.co.uk/2020/04/22/windows_98_css/> of the “Windows-98” look for your web pages. Personally, I can relate to this comment of the author: “Buttons just don't look like buttons anymore, it's so sad”. Basically, UI experts nowadays seem to be concentrating more on fashion, and the whole concept of “usability testing” has gone out the window.

Stripe Is Silently Recording Your Movements On Its Customers' Websites
by Peter Reutemann 23 Apr '20

23 Apr '20

'Michael Lynch, blogger and former software engineer at Microsoft and Google, discovered that the payment processing platform Stripe and its official JavaScript library records all browsing activity on its customers' websites and reports it back to the company. Lynch says this data includes the following: 1. Every URL the user visits on my site, including pages that never display Stripe payment forms 2. Telemetry about how the user moves their mouse cursor while browsing my site 3. Unique identifiers that allow Stripe to correlate visitors to my site against other sites that accept payment via Stripe In his blog post, Lynch shares what he found, who else it affects, and how you can limit Stripe's data collection in your web applications. Here's how he says he made the discovery: I discovered this by accident while adding paid plans to my portfolio rebalancer. As part of development, I was using an HTTP proxy that allows me to inspect HTTP traffic from my browser. After successfully implementing my app's payment flow with Stripe, I noticed that every page navigation generated a new HTTP POST request to a Stripe URL. This was strange because none of the pages I visited contained any calls to Stripe's library. In fact, my app doesn't collect payment information from users until they create an account, but Stripe was making HTTP requests when I landed on my app's homepage as a brand new user with no cookies or stored credentials. "I looked around for an official disclosure from Stripe about this behavior, but I couldn't find anything," adds Lynch. "The closest I found is this vague paragraph on their npm package description, which the Stripe support rep quoted to me: 'To best leverage Stripe's advanced fraud functionality, ensure that Stripe.js is loaded on every page, not just your checkout page. This allows Stripe to detect anomalous behavior that may be indicative of fraud as customers browse your website.'" "The privacy policy is a bit more specific about the data they collect, but it implies that they're collecting this data on stripe.com rather than on customer sites," writes Lynch. "Worryingly, the privacy policy also includes loose wording that allows Stripe to sell this data to advertisers: 'When you visit our Sites or online services, both we and certain third parties collect information about your online activities over time and across different sites to provide you with advertising about products and services tailored to your individual interests.'"' -- source: https://yro.slashdot.org/story/20/04/22/0023222 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Vivaldi Browser Gets Built-in Tracking Blocker, Goes GA on Android
by Peter Reutemann 23 Apr '20

23 Apr '20

'Vivaldi, the browser launched by former Opera CEO Jon von Tetzchner, has long positioned itself as a highly customizable alternative to Chrome and Firefox for power users. Today, the team is launching version 3.0 of its desktop browser, with built-in tracker and ad blockers, and it's bringing its Android browser out of beta. From a report: I've long been a fan of Vivaldi, but the company was relatively late to the tracking protection game. Now it's doubling down by integrating a blocklist powered by DuckDuckGo's Tracker Radar. Like competing browsers, Vivaldi offers three blocking levels that users can easily toggle on and off for individual websites. Those blocking levels are relatively blunt, though, with the options to either block trackers, block trackers and ads, or disable blocking. Competitors like Edge offer slightly more nuanced options for blocking trackers, though I would expect Vivaldi to adopt a similar scheme over time.' -- source: https://slashdot.org/story/20/04/22/1550251 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Edge TV Now Online-Only
by Lawrence D'Oliveiro 22 Apr '20

22 Apr '20

If there is anybody else besides me who wondered what happened to Edge TV, as of the beginning of this month it is no longer on Freeview, it can now only be viewed as an online stream <https://www.stuff.co.nz/entertainment/tv-radio/113928839/the-edge-tv-remove…>. In the last few days of June, there was a promo announcing that it was going HD, but I don’t recall it mentioning that it was leaving the broadcast airwaves. Quote: MediaWorks chief executive Michael Anderson says the move is in line with audience trends, which show people primarily consume music videos online. While that may be mostly true, personally I would go look for videos on YouTube after seeing them first on Edge TV.

Discord Switching From Go To Rust
by Lawrence D'Oliveiro 22 Apr '20

22 Apr '20

Came across this blog post <https://blog.discordapp.com/why-discord-is-switching-from-go-to-rust-a190bb…> explaining why Discord, which has been using Google’s Go language to implement its services, has now decided to rewrite them in Mozilla’s Rust. The problem was garbage collection. Go has a similar memory-allocation model to Java or LISP, where you can create objects and simply forget about them when you don’t need them any more, and a background process will automatically reclaim the storage at some point. The trouble is, that reclamation process (the “garbage collector”) tends to be the source of performance bottlenecks in the system. Not to mention that the memory usage of your program can grow to fill all available space, unless you impose arbitrary limits on it. Languages like Perl and Python use a hybrid model, where objects have reference counts attached to them, keeping track of how many other objects or variables still point to them, so they can be automatically freed when the count goes to zero. There are cases where this isn’t enough, and in those cases a full garbage-collection process kicks in. One benefit that I certainly observe with this is that memory usage for a program can remain reasonable, even after it has been running for a long time. Rust avoids the whole issue in a clever way, by having the compiler enforce memory-ownership restrictions in the language itself, so memory can be correctly allocated and freed without resorting to a garbage collector. The result is that Rust can achieve significantly higher performance than Go, while avoiding most of the attendant risks of dumping the whole responsibility for memory management on the programmer, as is done in languages like C++ and C.

Google Wants To Phase Out Browser User-Agent Strings
by Lawrence D'Oliveiro 21 Apr '20

21 Apr '20

Google wants to reduce the large amount of information browsers typically pack into the “User-Agent” header lines they send out, but this has been delayed for now <https://www.theregister.co.uk/2020/04/20/google_useragent_string_revision/>. This makes sense. Sites should not be changing their behaviour based on how browsers identify themselves, but on what functionality they actually support. But I wonder what this will mean for sites that routinely block the default user agents for scripting tools like wget and Python’s urllib ... But who is objecting to Google’s plan? Advertisers, who are apparently relying on user-agent checks as an important part of their mechanism for detecting ad fraud. Which is quite an incredible admission, really.

GhostBSD
by tom butz 21 Apr '20

21 Apr '20

There still are several BSDs around: OpenBSD, NetBSD, FreeBSD, TrueOS and GhostBSD. They usually lack desktops, but GhostBSD has got one, and it looks good. I started with the latest version, 20 something: that one didn't work properly for me Then I used 18.10 where there were issues with the LAN, and finally everything worked using 19.10 - both on my laptop and an old Macmini. BTW, I've also installed it on an external USB3-drive (500 GB) and it can boot from it. GhostBSD supports the ZFS-filesystem and will read/write from/to msdos and linux filesystems. I haven't tried writing to an ext4 system, only read from ext-sticks. You need to do some extra work to enable read/write to extfat. LAN and WiFi worked well and Firefox is very fast. My laptop has 6 GB of RAM and I ran everything in single-user mode, just to get some extra speed. Thanks go to Peter who found the older versions on a US-server - GhostBSD is made in Canada.

XCP-ng Motors Along

First I heard of this XCP-ng project, which aims to produce an open-source version (!) of XenServer <https://www.theregister.co.uk/2020/04/20/xcpng_100000_download_milestone_an…>. To add to the surprise, it is actually getting support from the Xen Project.

As Raspberry Pi Sales Skyrocket, Eben Upton Applauds Efforts of Open Hardware Community
by Peter Reutemann 20 Apr '20

20 Apr '20

'"Sales of Raspberry Pi's single-board computers hit 640,000 in March, the second-biggest month for sales since they started selling," reports TechRepublic, "as consumers flocked to inexpensive ways to work and learn from home." But that's not all, Eben Upton tells them: With the pandemic having highlighted shortages in personal protective equipment (PPE), 3D-printing manufacturers and hobbyists have been building face shields printed on plastic acetate that can be quickly assembled and delivered to hospitals, for free. "A lot of that is Pi-driven," Upton explained, noting that OctoPrint, which is the most popular platform for managing 3D printers, runs on Raspberry Pi... "[M]aking face shields seems to be a community effort. You have people with a home printer, printing these things once a week and then going to a post office and sending them," he said. "Then you'll have some people sat in a hack space receiving the parcels, cutting the acetate and the elastic, assembling them into face shields then sending them to the hospital. It's amazing." Upton suggested this effort could eventually be ramped up to a "massively distributed scale", with the benefit of open source being that, once you have a good design that works, it can be rapidly iterated. In the long term, this could even include the ventilators themselves, he said. "One thing we're seeing with this is people finding a niche within which open hardware really works," he said.

Will Companies Cut Open Source Investment Because of COVID-19?
by Peter Reutemann 20 Apr '20

20 Apr '20

'The editor of TFIR posed an interesting question to Rob Hirschfeld, the Founder/CEO of RackN (which automates and integrates bare-metal infrastructure). Will the financial impact of the COVID-19 pandemic affect the sustainability of open source software? Hirschfeld responded: "The idea that big companies are maintaining open-source projects for the community good is going to get tested, as companies look for places where they can conserve revenue. I think that's a really critical thing." "The same is going to be true with open-source startups that are hoping to monetize support or consulting but have no real gate across the front of their infrastructure... Companies might decide they can use the open-source project and not pay the sustaining engineers that are working in that project. "These are really serious concerns about the whole open-source model, which relies on goodwill and free money."' -- source: https://news.slashdot.org/story/20/04/19/0452247 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
