I have been delving into Advanced Prompt Engineering and Security techniques for Large Language Models (LLMs). As an exercise, I have created a custom GPT in ChatGPT to help practice spelling of English words. Spell It GPT is secured with Advanced Prompt Engineering techniques to guard against common attack vectors, including Direct Prompt Injection, Prompt Leaking, Role Playing, Simulation, DAN and Code Injection. Spell-It-GPT Play with the Spell It GPT and try to break it. It is not impossible but (probably) fairly difficult to do ;) Regardless, practice spelling and have fun! ...

You can get a free commemorative NFT if you met me at All Things Open Conference in Raleigh, NC. DM me at @ashtewari for the code to redeem your POAP NFT Visit https://app.poap.xyz/claim/ and enter your code Enter your Ethereum address (or ENS/Email) Mint POAP NFT Check [Free minting on Gnosis] for free minting of NFT on xDAI chain If you uncheck this box you can migrate to Ethereum mainnet now but you will have to pay for that transaction. You can also migrate to mainnet later if you wish. Click on Mint POAP button Your NFT will be confirmed after the minting is complete. ...

Mythril is an open-source security analysis tool for EVM bytecode, courtesy of ConsenSys. It is also a component of their Security Analysis Service - Mythx. Mythril detects security vulnerabilities in smart contracts built for Ethereum and other EVM-compatible blockchains. Vulnerabilities found by Mythril are reported with reference to the weaknesses listed on the Smart Contract Weakness Classification Registry (SWC Registry). I will use two entries from SWC Registry for the examples in this article: ...

KhelCoin (KHEL) is an ERC-20 token available on Ethereum blockchain. It is a Smart Contract created with Solidity, OpenZeppelin, Truffle, Ganache, Remix, web3.js and VSCode. It is currently available on Rinkeby test network. It will be launched on the Mainnet in the near future. You can get KHEL coins from this website - KHEL Coin ICO Head over to the ICO website. You will be prompted to install Metamask and connect to your account on Rinkeby testnet. Click on “Buy KHEL Coins” button to get your own coins! ...

Kusto query language can be used to get insights into Azure Kubernetes Service (AKS) clusters. Container insights collects data from AKS clusters and forwards it to Log Analytics workspace, if enabled for a cluster. This data is available for querying in the Azure Monitor. Here is an example of how you can query the pods not in running state in specific namespaces. KubePodInventory | where Namespace in ("dv","test","prod") | where ContainerStatus != "Running" | where ContainerStatusReason !in ("", "Completed") | distinct Namespace, Name The following query includes the name of the AKS cluster and renders the output as a stacked bar chart. ...

You can connect to Azure Kubernetes Service (AKS) nodes using ssh. It is documented here: Connect with SSH to Azure Kubernetes Service (AKS) cluster nodes for maintenance or troubleshooting. I needed to access nodes on the System node pool for collecting some logs recently, but the process documented above was not working for me. It turns out that there were two different issues, both related to adding your SSH keys to the nodes in a virtual machine scale set (VMSS). ...

Azure Kubernetes Service (AKS) supports specific versions of Kubernetes. It is necessary to regularly monitor the release of new versions and upgrade your AKS clusters to supported versions in order to remain in compliance with AKS Kubernetes Version Support Policy. AKS announces the planned date of a new minor version release and corresponding old version deprecation via AKS Release notes at least 30 days prior to removal. An email notification is sent to the subscription administrators with the planned version removal dates. You get 30 days from version removal to upgrade to a supported minor version release. Patch versions can be released anytime and you get 30 days from the removal date to upgrade to a supported patch version. ...

Universal Windows Platform (UWP) provides a common app platform on every device that runs Windows 10. The core APIs in UWP are the same on all Windows devices – including Desktop PC, Mobile Phone, XBox, Hololens, IOT devices and others. You can target specific device capabilities of a device family with extension SDKs, but you don’t have to do that if you are only using core APIs. Those core APIs include a very impressive set of UI capabilities. What that means is that you can create a UWP application using C# and XAML which will run on an ARM based processor on Raspberry Pi – because Windows 10 IOT Core runs on that. ...
