Glowing silicon nanowire reveals how to put optics in your CPU

Silicon-germanium alloy glows, may be future CPU optical communication laser.

The key term in integrated circuits is integrated. The ability of fabrication facilities to integrate things sets limits on what processes are available, and what materials can be safely used. As soon as you suggest a different material or process, the whole chain is broken, and anybody suggesting it should expect people questioning your suitability for your current position. “Compatibility” is why you will not find laser-powered integrated circuits in your laptop.

The ability to make lasers using integrated-circuit-compatible materials, however, may have gotten a boost, with a demonstration of glowing (but not yet lasing) silicon.

Looking on the bright side

Optics and lasers are the backbone of high speed data transmission. You do not use copper wires to transport data at 1Tb/s. Instead you will use glass and some finely tuned and very expensive laser diodes. But laser diodes are made using processes and materials that are not compatible with those used to make integrated circuits. So, while it is possible to create, say, an optical interconnect between a RAM module and a CPU, you have to somehow glue the optics to the silicon chip in exactly the right location. Research labs are happy to sacrifice PhD students to such ventures, but PhD-bots don’t scale well, are high maintenance, and their deployment leads to dark looks.

Apple and Google detail bold and ambitious plan to track COVID-19 at scale

In a bold and ambitious collaboration, Apple and Google are developing a smartphone platform that tries to track the spread of the novel coronavirus at scale and at the same time preserve the privacy of iOS and Android users who opt in to it.

The cross-platform system will use the proximity capabilities built into Bluetooth Low Energy transmissions to track the physical contacts of participating phone users. If a user later tests positive for COVID-19, the disease caused by the coronavirus, she can choose to enter the result into a health department-approved app. The app will then contact all other participating phone users who have recently come within six or so feet of her.

The system, which Google and Apple described here and here respectively, applies a technological approach to what’s known as contact tracing, or the practice of figuring out everyone an infected individual has recently been in contact with. A recently published study by a group of Oxford researchers suggested that the novel coronavirus is too infectious for contact tracing to work well using traditional methods. The researchers proposed using smartphones, since they’re nearly ubiquitous, don’t rely on faulty memories of people who have been infected, and can track a nearly unlimited number of contacts of other participating users.

Danish Court Throws Out Three Piracy Cases, Plaintiff Had No Right to Sue

A High Court in Denmark has thrown out three copyright infringement cases against alleged BitTorrent pirates, filed by a middle-man operation with links to notorious copyright troll Guardaley. The court found that the company produced no content, distributed none, and wasn’t in a position to sue. The ruling could prove pivotal for hundreds, perhaps thousands of cases still pending in the country.

Legal actions against file-sharers come in all shapes and sizes but perhaps the most common are the mass lawsuits that target alleged BitTorrent users.

Hundreds of thousands of these cases, which usually begin with a demand for cash settlement, end when the target pays up an amount to have a supposed lawsuit disappear. More rarely, however, cases end up in court and under the scrutiny of a judge, things don’t always go so well.

Like many countries in Europe, alleged file-sharers in Denmark have been receiving letters claiming that since they’ve been caught sharing porn without the copyright holders’ permission, they must now pay an informal fine. The threat for non-payment is a court case but for one company and its beneficiaries involved in a pretty big scheme, this has not gone to plan.

Copyright Management Services (CMS) is known for its involvement in mass copyright litigation. Working with Danish law firm NJORD Law, it previously demanded the identities of thousands of individuals in Sweden so it could pursue them for settlements relating to alleged porn downloads. It is also very active in Denmark.

CMS was incorporated in the UK during October 2014. Until fairly recently its sole director was Patrick Achache, who also operates German-based BitTorrent tracking company MaverickEye. Both were part of the notorious international trolling operation Guardaley, which recently changed ownership.

While actual copyright holders are perfectly able to sue alleged file-sharers, there is a tendency among some mass litigation outfits to use middle-man companies instead. There are theories that their purpose is to act as a buffer to protect the actual copyright holders should lawsuits go wrong but in the cases brought by middle-man CMS in Denmark, its involvement in the chain has caused things to unravel.

The development comes after CMS demanded cash settlements from three individuals who failed to pay and were later taken to court. The defendants were ISP account holders of IP addresses that CMS claimed were connected to illegal file-sharing. In all cases, district courts found in favor of CMS, ordering the defendants to pay 7,500 DKK ($1,039) to the company.

When the cases went to appeal, the defendants denied they committed the copyright infringements alleged by CMS. They further alleged that CMS was not a producer of the content, was not a distributor of content, and had no documentation to prove that it was entitled to sue on behalf of the actual copyright holders.

Countering, CMS referred to its successes in the district courts and insisted that it did indeed have agreements in place to prosecute the cases against the alleged pirates. That assertion was rejected this week by the Eastern High Court.

“In all three cases, the High Court found that the company had not proved that it had legal capacity to conduct the cases in its own name,” a statement from the court reads.

As a result, all three cases were dismissed.

“The cases are part of a large number of cases pending before the courts, about the sharing of films, in some cases porn films. The three cases are the first of such cases decided by the Eastern High Court,” the statement notes.

Quite how many other cases Copyright Management Services has filed on the same grounds (i.e with no right to sue) is unclear but having these cases thrown out could present problems for the company. In respect of the company itself, interesting facts are available from public sources.

As previously mentioned, Patrick Achache was the sole director of CMS. However, on November 19, 2019, he ceased to be a director and what Companies House describes as a ‘person with significant control’. In his place as the new officer with ‘significant control’ stepped Lubesly Tellidua, who has the same name as a beauty queen from the Philippines.

This could have been a complete coincidence but thanks to detective work by Danish news site K-News, it’s possible to confirm that Lubesly Tellidua the beauty queen is not only the new person in control of CMS but is also directly linked to Achache, as the photograph in their article shows.

A new director was also appointed to CMS last year, Eleanor Elizabeth Powell of Brecon, Wales, who chose to register modified names and addresses across two different companies – Copyright Management Services Ltd and Powtex Limited. Adding a middle name and tweaking the details of an address is enough for Companies House not to link the same director to two companies, at least without manual research.

Anyone interested in venturing further down the CMS rabbit hole might consider visiting Open Corporates where several familiar names in copyright trolling and anti-piracy enforcement can be found doing business, past and present.

When school is online, the digital divide grows greater

School closings, e-learning tough for the 20% of rural students without broadband.

Like many students around the world, Nora Medina is adapting to online learning. But Medina, a high school senior in Quincy, Washington, who also takes classes at a local community college, faces an additional challenge: She doesn't have reliable Internet service at home. She lives 7 miles outside of town where she says neither cable nor DSL Internet is available.

She can access the Internet on her phone, and her family has a wireless hotspot, but she says the service isn’t up to the task of doing homework online. "It's hit and miss," she says. "Sometimes I can watch a video, but sometimes I can't even refresh a page, or it will take minutes to load something on a page."

Washington governor Jay Inslee this week said the state’s schools will be closed for the rest of the school year. Quincy High School is still planning how best to help students finish the year. But Medina’s classes at Big Bend Community College have shifted online. "I'm just going to hope the hot spot works and wish for the best for my final quarter," she says. "If that doesn't work, I'll do my work from my car in the parking lot at the library to access their Wi-Fi."

The Pirate Bay’s Main Domain ‘Returns’ After a Month of Downtime

After a month, The Pirate Bay is accessible again through its main domain name. The unannounced comeback follows after Thepiratebay.org sent traffic to a black hole for nearly a day. Initially, Cloudflare’s nameservers were removed from the whois records but the site is now reachable again through a new set of Cloudflare nameservers. There are also some other changes.

Over the past several weeks, The Pirate Bay has suffered prolonged downtime. For many people, the popular torrent site was completely unreachable through its main Thepiratebay.org domain.

While regular visitors knew that the site was still accessible over the Tor network, through a separate domain, the problems were unusual.

Yesterday, the situation for more confusing when the .org domain was updated. The usual Cloudflare nameservers were removed and replaced by EasyDNS nameservers. In addition, all traffic to the domain was sent to 127.0.0.1, which essentially meant that all requests dumped into a local black hole.

Without an official explanation from the Pirate Bay team, these changes were fuel for speculation. Today, however, the situation has already completely changed again.

Starting a few hours ago, Thepiratebay.org domain is back online. After another update of the domain records, it is operational again. Not just that, it also uses Cloudflare’s services.

There is a small update though. Over the past few years, The Pirate Bay used the dean.ns.cloudflare.com and sofia.ns.cloudflare.com nameservers. Today, the site uses deb.ns.cloudflare.com and sevki.ns.cloudflare.com.

Other than the nameserver update, nothing has changed domain-wise. The domain is still registered through Fredrik Neij, one of the original Pirate Bay co-founders, and EasyDNS remains the registrar.

Why the Cloudflare nameserver changed is unknown. It is possible, however, that the domain had to be operated through a separate Cloudflare account for some reason.

Previously, we were told that The Pirate Bay team would use the downtime to implement some updates to the code. While that doesn’t have to be visible, there are a few changes in the site’s appearance as well.

Several links have been stripped from the homepage now, including those to the blog and the about page. In addition, the ‘login’ and ‘register’ links simply point back to the homepage. In addition, the site uses the torrindex.net domain to serve some static content.

Perhaps these modifications are part of the previously announced changes, or it’s something that’s still being worked on. Interestingly, the Tor version of the site still shows the old look, with all the other links intact.

We will keep an eye on any other changes during the days to come. If any new information becomes available we will update this article accordingly.
