  • syncToy Setup in one step

    Tired of syncToy: “Install .NET Framework 2.0.5072 ..” error message when installing? The site you get redirected to, when following the prompt in the dialogue is useless. Maybe like me, you installed 2 or even 3 versions of .NET only to find that none of them works. Wouldn’t it be great to have everything in…

  • Fixing “Incorrect password” problem when connecting to Wi-Fi on iOS devices

    I noticed a few days ago, that my iPhone wouldn’t connect to my WiFi any more. It kept saying “incorrect password” even though the password hadn’t changed. So I tried a few things: Forget Wi-Fi network and reconnect -> didn’t work Reset network settings -> Just lost all my Wi-Fi passwords, thank you! Reboot and…

  • Why there’s a ‘value’ in value proposition!

    Everyone who starts or runs a business, designs or markets a product will come across the necessity to create a value proposition. Something that adds values to the inputs of the business or product to the customer. Ideally that proposition is unique, and helps the business or product stand out. I’ll use the term business…

  • The immediacy of tools

    „The medium is the message“ – this quote by Marshal Mc Luhan has many truths and depths hidden in a surprisingly simple sentence. I don’t think it starts out that way.

  • CRYPTO CURRENCY MINING AND RENEWABLE ENERGY – A MATCH MADE IN HEAVEN

Especially these two technologies have one problem in common: No one can predict how much electricity will be produced, even just a few minutes away. This makes alternative energy sources mandatory as a means of compensation. Very…

  • Cryptocurrencies and Pollution

    Why are cryptocurrencies and pollution linked, as was reported here and here? Let’s start by reflecting on how a blockchain works. A blockchain is a number of linked data segments, called blocks, that are signed by a cryptographic function. Each new block contains a link, in the form of that cryptographic signature, to the last block before it,…

  • Bitcoin Block Date Calculator

    Didn’t you always want to know at what date a specific Bitcoin block would come? Or what block number a specific date corresponds to? Now, I know, block time isn’t always the same. This can never be exact science. However, block time has been pretty consistent on average over the last few years. So I created a…

  • Regulating Cryptocurrencies – Why? and How?

    “Cryptos are awesome, but they need to be regulated!!” I heard this sentence so often, and from so many different, smart people. It was nauseating. Cryptocurrencies were created so that central authority regulation was NOT, and I repeat, NOT needed. That was the idea behind Satoshi Nakamotos original Bitcoin. It was created in the tradition…

  • Bitcoin hard fork security – what you need to know

    Bitcoin Gold (BTG) hard forked the Bitcoin blockchain at block #491407 to create an alternate chain, where miners can use GPUs instead of single-purpose ASICs for mining. BTG also introduced some improvements like bigger blocksize and shorter time between blocks for higher transaction bandwidth. While the whole motivation behind BTG seems to be profit, especially…
