A neural network connection that adds the input of a layer directly to its output, forming a skip connection that enables stable gradient flow during backpropagation in very deep architectures. Residual connections mitigate the vanishing gradient problem and allow networks of hundreds of layers to be trained effectively, forming a foundational component of ResNet and Transformer architectures.

GUI Tools for Connecting to OpenVPN
- Both KDE and GNOME offer plugins for their network manager applets that allow VPN connection to an OpenVPN server. The necessary plugins are:
- KDE: network-manager-openvpn-kde
- GNOME: network-manager-openvpn-gnome
- More than likely, those plugins will not be installed on the distribution by default. A quick search using the Add/Remove Software utility will allow for the installation of either plugin. Once installed, the use of the network manager applets is quite simple, just follow these steps (I will demonstrate using the KDE network manager applet):
- Open up the network manager applet by clicking on the network icon in the notification area (aka System Tray.)
- Click on the Manage Connections button.
- Select the VPN tab.
- Click the Add button to open up the VPN type drop-down.
- Select OpenVPN from the list.
- Fill out the necessary information on the OpenVPN tab
- We look forward to seeing you at the ComfyUI for Fashion and Brands event! If you have any questions or concerns, please don’t hesitate to reach out to the event organisers.
- Remember to bring your laptop and a passion for fashion, innovation, and AI-driven creation. Let’s push the boundaries of generative AI together!

Mobile phone users in Nigeria, Tanzania, South Africa, Kenya and five other African countries can now send and receive bitcoin without a smartphone or Internet connection. Just a basic feature phone and text code will suffice, thanks to a digital wallet from software developer Ngako. No internet connection and low power handsets means using SMS and the Lightning network, with the phones SIM acting as the wallet private keys.

President Bukele, who has been a vocal proponent of Bitcoin, stated that the adoption of Bitcoin was a way to promote financial inclusion and stability in the country, where more than 70% of the population is unbanked or underbanked. In a tweet, he stated, “Bitcoin will have the same value as the US dollar. We will support both. They will have the same power of purchase and will be accepted in the same way.”
-
The move was met with a lot of media attention and reaction, with some praising it as a bold and innovative step, while others raised concerns about the volatility of Bitcoin and their potential impact on the economy. President Nayib Bukele himself has faced criticism for his handling of political power and some of his actions have raised concerns about the potential for abuses of power. In 2021, President Bukele faced widespread criticism for his handling of the legislative process and his use of the military to secure the Legislative Assembly building during a political standoff with lawmakers. This led to allegations of intimidation and a violation of democratic norms, and raised concerns about his willingness to use force to achieve his political goals. Additionally, President Bukele has faced criticism for his use of social media to communicate with the public and his tendency to bypass traditional media outlets, which has raised concerns about the potential for censorship and the manipulation of information. With that said he seems much loved in the country, and the previously appalling safety statistics of the nation have radically improved.

There has been a significant increase in the adoption of Bitcoin in El Salvador (to around 12%) and apparently increased inward investment to the country. Many businesses, both small and large, have started accepting Bitcoin as a form of payment, and there has been a growing interest in Bitcoin among the general population. Additionally, the government has been actively promoting the use of Bitcoin through various initiatives. There have also been efforts to educate the public about Bitcoin and its potential benefits, including increased financial security and reduced transaction fees compared to traditional banking systems.
-
Overall, the adoption of Bitcoin in El Salvador has been positive, far outstripping the number of people in the country with traditional bank accounts, and has the potential to greatly impact the country’s economy and financial sector. However, it is important to note that there are still challenges to overcome, such as regulatory and infrastructure limitations, as well as ongoing concerns about the volatility and stability of Bitcoin.
-
Overall, the adoption of Bitcoin in El Salvador marks a significant step forward in the mainstream acceptance and adoption of Bitcoin and has the potential to set a precedent for other countries to follow. However, it is important to monitor the situation and assess the long-term impacts on the economy and financial sector.

Academic Context
-
-
Residual connections are architectural motifs in deep neural networks where the input to a layer is added to its output, forming a “skip connection” or shortcut.
-
This design enables layers to learn residual functions ( F(x) = H(x) - x ), simplifying the learning process by focusing on the difference from the identity mapping.
-
Residual connections were popularised by the ResNet architecture introduced by He et al. in 2015, which won the ImageNet challenge and addressed the vanishing/exploding gradient problem in very deep networks.
-
The academic foundation lies in improving gradient flow and convergence stability in deep networks, enabling training of hundreds of layers without degradation in performance.
Current Landscape (2025)
-
Residual connections are now a standard component in a wide range of deep learning architectures beyond computer vision, including transformers (e.g., BERT, GPT models), reinforcement learning systems (AlphaGo Zero, AlphaStar), and protein folding models (AlphaFold).
-
These connections facilitate training of very deep models by providing alternate gradient pathways, mitigating vanishing gradients.
-
Industry adoption is widespread across AI research labs and commercial platforms, with implementations in frameworks such as TensorFlow, PyTorch, and JAX.
-
In the UK, leading AI research centres in Manchester, Leeds, and Sheffield incorporate residual connections in their deep learning projects, particularly in computer vision and natural language processing.
-
Technical limitations include increased computational overhead due to deeper architectures and challenges in optimising very deep residual networks without overfitting.
-
Standards and frameworks have evolved to include residual blocks as modular components, with best practices for their integration and tuning documented in major deep learning libraries.
