Summary: We're still running the site 24/7 every day/week of the year; we're managing to cope with slower news cycles

WE RECENTLY passed the sixteenth anniversary of this site, which is peaking in terms of traffic (record levels and all-time highs for several consecutive weeks). This weekend is very, very slow for news. Very.

We're typically managing to cope with the decline of journalism by digging deeper, finding lesser known sites such as blogs. We're hoping to reach the twentieth anniversary of the site. That's 2024.

Camel

When a human doesn't know what to do and people don't know how to tackle the real issue, the animals are becoming the sacrifice. Billion of animals were lost to bushfires alone and millions are slaughtered every day, yet the audacity to kill the camels is astonishing. I wonder what would be the humans' reaction if the animals called for human culling. Think about it.

Koalas Need Our Help

Watching videos/photos of Koalas being rescued from a charred/burning forests in Australia is heart-breaking and devastating. More than 350 Koalas are reported being dead and these numbers are growing. Those who live far from Australia (just like me) can't help physically rescue them, but a small amount of money/donation to sustain the hospital/facilities, volunteers and rescuers is of great help. Koala is just one of the many species that perish from the bushfire and they need our help, so please donate through the GoFundMe page and through other legitimate websites. Help those who support animal welfare.

Meng Meng

About 8 months ago we had the chance to meet Meng Meng (above) and Jiao Qing, the female and male pandas on loan to Berlin Zoo in Germany. I took lots of photos with them and we stayed in their Pagoda sanctuary a little longer. Seeing them eating, napping and wandering inside their secured place brings joy to my heart. I don't really like seeing animals in the zoo, but if this is the only way to keep and protect them from any harm or from becoming extinct, then so be it. Today, in the news (video) the two adorable pandas became parents as they were having twins; this is good news and I'm so happy for them both. To Meng Meng and Jiao Qing (and also to Berlin Zoo), congratulations!

Mask of death

Everything Microsoft touched has died. Remember Nokia, Yahoo and Novell? What happened to these companies and where are they now? This is exactly what Microsoft wants to do to Linux because they don't innovate and they can't compete; so they infiltrate. Sooner or later Linux will be part of those latter companies. Something to watch out for.

Orangutans are some of the most solitary animals critically endangered as human consumption grows; Ban Palm oil Industry.

Orangutan

Orangutans are some of the most solitary animals critically endangered as human consumption grows.

Orangutans are currently only found in the rainforest of Borneo and Sumatra where both species are endangered. The orangutans' habitat has decreased and is rapidly being devastated by loggers, palm oil plantations, gold miners, and unnatural forest fires.

Watching videos of orangutans over hundreds of times is nerve-wracking, seeing them in distress and in great trauma as babies watch their mothers hacked and killed by poachers. They are using their machete which is so inhumane, as many of these infants die without the help of their mother and some other infants are sold as pets, ending in the hands of their 'owner', maltreated and malnourished, making their situation even worse. This happened because of the humongous demand and consumption of humans. Guilt is creeping on me; while enjoying my food and applying all the cosmetics for vanity it is like slaughtering an innocent and beautiful primate slowly and accurately. I wasn't thinking at all; I'm closely blinded of my needs, having never bothered to think that somewhere out there someone is tormented. I can't let this happen any longer. I must act and make a stand and be the voice of orangutans. I'm calling for everyone to ban and stop buying palm oil products. We must stop deforestation and the palm oil industry, strongly and swiftly before orangutans and all other animals sail into extinction.

Beijing Zoo is No Place for Pandas

Pandas in Beijing Zoo
Photo credit: Nick Hopkins

I am a Panda lover. I work as a support engineer in an I.T company here in the United Kingdom. Most of my spare time is spent watching different Panda videos -- both old and new videos. Basically, it is my therapy; a 'stress release' for me. I find them to be adorable and precious creatures. As a matter of fact, I would like to volunteer to come to Sichuan. I want to experience and feel what it's like to be a Panda keeper, to be able to interact with them for real. The Panda is China's National Treasure, so it's a shame to watch the Panda videos from Beijing zoo, as the place is disgusting and not ideal for Pandas to live in (and for sure for all the rest of the animals who unfortunately got stuck in this prison cell).

The place looks like a ghost town. Lifeless and languished. Knowing that Pandas wear a thick fur on their body, can you imagine what it feels for them in 30C or 35C (summer temperature)? What it probably feels like all the time? Come on, if you really care, you must do something now, otherwise these Pandas will die. Please bring them back to their sanctuary where they really belong.

Earlier this month my husband and I needed a replacement for the Chromebook that I had installed Linux on after Christmas because the keyboard developed a fault. This was a good opportunity to get an upgrade and to connect the 28-inch monitor to it, allowing us to watch Wimbledon over the Internet (we don't watch TV).

How my uncle became a Linux user

Filed under
Linux

It has been a month since my relatives from Bradford visited us here in Manchester. Our usual routine if they come to spend the holidays with us is to go to the gym to work out, to run on the treadmill and play pingpong. The best part of the workout, which we enjoy the most, is swimming afterwards. We get relaxed at the jacuzzi and then get hot and sweaty inside the sauna. It is a good exercise and offers relaxation after a stressful day of work. We have so much fun in the gym.

We arrived home around 8:00 pm after having a good round of walk in Manchester City Stadium. We were lucky to see the Manchester City football team; they had a match against Roma, so crowds were flooding in the streets. There were about a thousand spectators coming to watch the game who walked past us.
At home I prepared the meal. We had candlelights and red wine to enjoy while having our soup, vegetable salad and chicken for dinner; mango smoothies were the final dessert.

After the meal we chatted about the economy, healthcare, jobs, business, and technology in the U.K. I have learned a lot from Albert, my aunt's husband. He is an economist.

Albert explained to me that he was struggling with his PC. It was a brand new PC. It had a touchscreen and the laptop was thin and powerful. Albert's problem was not the laptop. As it turns out, his problem was Windows. The computer came with Windows 8. He already wasted a lot of money because shops exploited him. He did not even have an office suite installed. The computer was useless. He hardly used it. He hardly even had any files on it.

I then explained to Albert about GNU/Linux. I told him about Stallman and GNU. I also told him about the dirty tricks of Microsoft and about the true Bill Gates, including his involvement in GMO. Albert listened to me and he wanted to know more. I hope he learned something from me, just as I had learned from him.

The following morning I asked my husband for help. He was working all night and in the morning he was available to help Albert. Based on Roy's analysis, the machine was full of malware or some other mess. It was almost impossible to do anything with it. Windows 8 was hard to work with and it was hardly even possible to download and install a program like LibreOffice. The interface was confusing. It took ages to do very simple things.

Albert insisted that we should install GNU/Linux, but we didn't have a recent version of a distro at that time. Either way, Albert was so frustrated with Windows that he was willing to throw it all down the drain, along with his files.

This was my first time seeing Windows 8. I usually use Android or KDE. Microsoft Windows has become full of pop-ups, spam, marketing and other garbage. I am glad to use GNU/Linux and Albert will soon join us. By all means, Albert now wants to use Open Source and he already learns how to use LibreOffice.

  • By embracing blockchain, a California bill takes the wrong step forward.

    The California legislature is currently considering a bill directing a public board to pilot the use of blockchain-type tools to communicate Covid-19 test results and other medical records. We believe the bill unduly dictates one particular technical approach, and does so without considering the privacy, security, and equity risks it poses. We urge the California Senate to reconsider. The bill in question is A.B. 2004, which would direct the Medical Board of California to create a pilot program using verifiable digital credentials as electronic patient records to communicate COVID-19 test results and other medical information. The bill seems like a well-intentioned attempt to use modern technology to address an important societal problem, the ongoing pandemic. However, by assuming the suitability of cryptography-based verifiable credential models for this purpose, rather than setting out technology-neutral principles and guidelines for the proposed pilot program, the bill would set a dangerous precedent by effectively legislating particular technology outcomes. Furthermore, the chosen direction risks exacerbating the potential for discrimination and exclusion, a lesson Mozilla has learned in our work on digital identity models being proposed around the world. While we appreciate the safeguards that have been introduced into the legislation in its current form, such as its limitations on law enforcement use, they are insufficient. A new approach, one that maximizes public good while minimizing harms of privacy and exclusion, is needed.

  • Mycroft: an open-source voice assistant

    Mycroft is a free and open-source software project aimed at providing voice-assistant technology, licensed under the Apache 2.0 license. It is an interesting alternative to closed-source commercial offerings such as Amazon Alexa, Google Home, or Apple Siri. Use of voice assistants has become common among consumers, but the privacy concerns surrounding them are far-reaching. There have been multiple instances of law enforcement's interest in the data these devices produce for use against their owners. Mycroft claims to offer a privacy-respecting, open-source alternative, giving users a choice on how much of their personal data is shared and with whom. The Mycroft project is backed by the Mycroft AI company. The company was originally funded by a successful one-million-dollar crowdfunding campaign involving over 1,500 supporters. In recent years, it has developed two consumer-focused "smart speaker" devices: the Mark 1 and Mark 2. Both devices were funded through successful Kickstarter campaigns, with the most recent Mark 2 raising $394,572 against a $50,000 goal. In the press, the company has indicated its intention is to focus on the enterprise market for its commercial offerings, while keeping the project free to individual users and developers. On the subject of developers, contributors are expected to sign a contributor license agreement (CLA) to participate in the project. The actual CLA was unavailable at the time of publication, but the project claims it grants the project a license to the contributed code, while retaining ownership of the contribution to the developer.

  • Accelerating the value of multicloud environments: A collaborative DevSecOps approach is critical

    Cloud Native development is not so much about where you run your application, but more about how you develop it. It is an interesting moment in time for enterprise developers, as more emphasis shifts to application modernization and cloud native development. The responsibility is shifting to the application for critical success factors for hybrid cloud environments, including security, reliability, and manageability. I have found that these “interesting” challenges are best addressed by collaborative, cross-disciplinary DevSecOps teams that understand the entire software development lifecycle. In this new environment, your role as developers is more demanding, and we all need better tools. You have increased responsibility for understanding and working directly with security engineers on governance and related management policies. You are being tasked with prioritizing service reliability, and the best practice is to address potential problems early in the application lifecycle. You also need to proactively detect and resolve potential issues with production environments before they have a negative business impact.

    At the start of the year I begun keeping a daily diary for work as a simple text file. I've used various other approaches for this over the years, including many paper diaries and more complex digital systems. One great advantage of the one-page text file was it made assembling my weekly status report email very quick, nearly just a series of copies and pastes. But of course there are drawbacks and room for improvement. vimwiki is a personal wiki plugin for the vim and neovim editors. I've tried to look at it before, years ago, but I found it too invasive, changing key bindings and display settings for any use of vim, and I use vim a lot. I decided to give it another look. The trigger was actually something completely unrelated: Steve Losh's blog post "Coming Home to vim". I've been using vim for around 17 years but I still learned some new things from that blog post. In particular, I've never bothered to Use The Leader for user-specific shortcuts.

  • When Will Open Source Hardware Become a Thing?

    my honest opinion, Free and Open Source Software (FOSS) is probably the best of all innovation to come out of the tech industry in the past four or five decades. As far as I can tell, the Open Source Initiative is predated by Richard Stallman’s famous Free Software Foundation (FSF) (1985), which itself is predated by his own GNU project (1983) which seems as if it pretty much kick-started what we would call Free and Open Source today. Whilst it is true that software programs were often shared amongst academics before GNU, the software industry was a fraction of what it is today and so I believe that it was indeed GNU that kicked it all off. [...] Open Source firmware and drivers have been harder to come by in general than software. However, there have been major efforts made by Open Source and Free Software community members to create projects such as Libreboot which aims to replace proprietary boot firmware. Firmware is often a more contentious issue than software since most hardware we buy comes with firmware baked in. Reverse engineering a device’s firmware is not necessarily a particularly easy task, at least not when compared to just rebuilding an existing software project (eg. LibreOffice and Microsoft Office). To make matters worse, It can be much easier for companies to embed potentially malicious code since it is harder to analyse. I think that Open Source firmware will slowly become a bigger thing. However, its growth will probably be driven by the rise of Open Source hardware. [...] We’ve also seen the introduction of devices for the everyday user (not just hobbyists and tinkerers) including mobile phones and laptops. The company Purism has recently released both Laptops and a model of mobile phone which seem promising. Unfortunately, their laptops do rely on Intel CPUs, even if they claim to have disabled the management engine. It does seem like it will certainly take a while for these devices to meet mainstream though. Still, promising…

  • TLS gets a boost from Arduino for IoT devices

    Arduino devices are a favorite among do-it-yourself (DIY) enthusiasts to create, among other things, Internet of Things (IoT) devices. We have previously covered the Espressif ESP8266 family of devices that can be programmed using the Arduino SDK, but the Arduino project itself also provides WiFi-enabled devices such as the Arduino MKR WiFi 1010 board. Recently, the Arduino Security Team raised the problem of security shortcomings of IoT devices in a post, and how the Arduino project is working to make improvements. We will take the opportunity to share some interesting things from that, and also look at the overall state of TLS support in the Arduino and Espressif SDK projects. When it comes to making a secure IoT device, an important consideration is the TLS implementation. At minimum, TLS can prevent eavesdropping on the communications, but, properly implemented, can also address a number of other security concerns as well (such as man-in-the-middle attacks). Moreover, certificate-based authentication for IoT endpoints is a considerably better approach than usernames and passwords. In certificate-based authentication, a client presents a certificate that can be cryptographically verified as to the client's identity, rather than relying on a username and password to do the same. These certificates are issued by trusted and cryptographically verifiable authorities so they are considerably more difficult to compromise than a simple username and password. Still, according to the team: "As of today, a lot of embedded devices still do not properly implement the full TLS stack". As an example, it pointed out that "a lot of off-brand boards use code that does not actually validate the server's certificate, making them an easy target for server impersonation and man-in-the-middle attacks." The reason for this is often simply a lack of resources available on the device — some devices only offer 32KB of RAM and many TLS implementations require more memory to function. Moreover, validating server certificates requires storing a potentially large number of trusted root certificates. Storing all of the data for Mozilla-trusted certificate authorities on a device takes up over 170KB in a system that potentially only has 1MB of available total flash memory. A general lack of education regarding the importance of security in this space unfortunately also plays a role. After all, TLS isn't the most straightforward subject to begin with, and having to implement it on a resource-limited platform does not make implementing it correctly any easier of a problem to solve.

  • Open-source CNCing

    Last year Sienci Labs finished its Kickstarter campaign for the open-source LongMill Benchtop CNC Router — its second successful open-source CNC machine Kickstarter campaign. CNC routers allow users to mill things (like parts) from raw materials (like a block of aluminum) based on a 3D-model. The LongMill is a significant improvement over the original sold-out Mill One and makes professional-quality machining based entirely on open-source technology a reality. As an owner of a LongMill, I will walk through the various open-source technologies that make this tool a cornerstone of my home workshop. Hardware The Sienci Labs LongMill is an impressive feat of engineering, using a combination of off-the-shelf hardware components alongside a plethora of 3D-printed parts. The machine, once assembled, is designed to be mounted to a board. This board, called a spoilboard, is a board the machine can "accidentally" cut into or otherwise suffer damage — designed to be occasionally replaced. In most circumstances, the spoilboard is the top of a table for the machine, and Sienci provides documentation on several different table builds done by the community. For builders short on space, the machine can be mounted on a wall. The complete 3D plans for the machine are available for download, including a full bill of materials of all of the parts needed. The project also provides instructions to assemble the machine and how best to 3D print relevant components. The machine is controlled by the LongBoard CNC Controller, and Sienci Labs provides full schematics [23MB ZIP] of that as well. All mentioned materials are licensed under a Creative Commons BY-SA 4.0 license. In addition to the open-source design of the machine itself, an open-source-minded community has formed around the project. The company's Facebook user group has 1,600 members, and an active community forum is hosted by the company, which discusses everything from tips to machine support. Community members contribute, among other things, various modifications to improve the original design or to add new features such as a laser engraver.

Intel’s recent announcement of an additional six months delay in delivering 7nm CPUs, pushing back its original roadmap by a year to late 2022 or 2023 has led to further questions about the company’s future dominance. The 7nm defects are severe enough that Intel says it will expand its outsourcing of manufacturing to TSMC.
