  1. any one else gets below error after you enter "dfx start",

    Error: Cannot find dfx configuration file in the current working directory. Did you forget to create one?

  2. i was just being nosy because i am not a computer person or techy BUT!!! but!!!! FROM WHAT i SEE, YOUR PRESENTATION AND SKILL IN TEACHING MAKES EVEN A ROCK LIKE ME UNDERSTAND…VERY GOOD!! TEACHING IS A GIFT AND YOU HAVE MASTERED YOUR GIFT

  3. Market cycle still hasn't met its balance, we keep going round in circles while waiting for that bullish run on a great support. However, in the mean time we could always ignore the market ups and downs and stay fully invested. Big thanks to Sarah Elizabeth for helping me earn over 12 btc by implementing her method and following her guide.

  4. The way you just went right into the segment was great. Straight news. Zero fluff. This was one of your best streams. More emphasis should be put into trading since it is way profitable than hodling. Trading went smooth for me as I was able to raise over 10.2 BTC when I started at 4.5 BTC in just few weeks implementing Katelyn Dibbert's daily trading signals and tips.

  5. I installed the software v 0.9.3 and my node is above 16 i initiated npm and deployed the problem arises when i start running npm start, it is a bunch of errors can someone help me to understand it?

  7. Has the way the topUp function changed since you did the video. I'm getting error : Refusing to install canister without approval

  8. Thank you a lot for this video. This is very interesting and informative. Keep posting like those amazing videos, this is awesome.

  9. Wow! The best video i have ever ever ever watched on YouTube in my 42 years of living on earth! Thank you for the amazing piece of knowledge

  10. Predicting< a reversal of a trend is risky, and even worse, I believe there is more to this market than we understand currently. When people are losing, they don't aim to increase their average, but that can only change if you have a personal trade guide and signal provider like that of JEREMY NIEDERSTADT which has made me almost 8.7 on a 2 btc Trade capital over the last 2 months. Make the wise decision. Markets fluctuate in cycles that can last anywhere from a few days to several years. In the case of BTC, it's difficult to make a bullish case simply from looking at the charts

  11. I got all the way to step 23 for installing DFX and my dfx location was in fact added to my path. However when I run dfx –version, I get Command 'dfx' not found. How can this be when all of the previous steps worked as illustrated in your video & install guide? 🤔

  12. as an asian American I must say your voice and accent is soo sexy.. I swear everytime you say "block" I just fold at the knees.. I think im in love lol

  13. At 2.06.09 i did mess around with it, but there is a problem, i can add 10000, check balance, its there, then try to remove 10000, it says cant be less than 0.

  14. I had some problems with starting the project
    First: $npm start – didn’t work, I got an error message. Solution: go to package.json file and overwrite to “webpack-cli” : “4.10.0”
    Second: after successfully running the app on the browser, the welcome message didn’t show up. A new installation of Chrome browser without any extensions didn’t work neither.

  15. Hey Angela! When I put in the command prompt, dfx new hello -it opened up the project, showed the Definity logo… but it doesn't have the extra Motoko code and HTML… like yours in the video. There's nothing (code, html…) in the file when I opened it in the VS code and it won't open up to server on npm start ??

  16. Great Content! How do the Ethereum network limitations change after the merge? Is it a good choice for Dapps now after the merge?

  17. Searched a lot on youtube.. but this is the one vid which made me understand evrything! thank you so much for this 🙌🙌

  18. Angela is a good instructor but doing motoko language I think she did it with some sorts of affiliations from the dfinity team…

  19. ~/ic-projects$ dfx start

    Error: Cannot find dfx configuration file in the current working directory. Did you forget to create one?
