    Don't know where to start

    Ok so I have been doing the iwd for 3 month now, I am on CSS. On this particular video, stefan says i should start coding this late in the game. I have been following the videos and doing the activity done it on my own, ex: making my own website while watching the video. So now......... I feel overwhelmed because i didn't start my own website from the jump. Its like i know what to do, but i don't know what to do. should i go over the videos again? I know its my fault. Any advice would be appreciated

  5. Okay, I re-downloaded them... looks like it's working now - Thanks!
  6. Hi, Send me an email: stefan at killersites ... and I will give you an alternative download. Or you can try redownloading the damaged zips. It happens sometimes.
  7. Hi - I just downloaded the Beginner's Killer Python 3 files. The Archive 0 zip file won't open. It says Windows cannot open the folder. The compressed Archive (zipped) folder c:\Archive 0.zip is invalid. I get the same message for Archive 3-A.zip and Archive 7.zip. The rest of the zip files open fine. I did try re-downloading Archive 0.zip file, but it still didn't unzip. Any ideas? I'm using a PC.

    Police Can't Force You To Unlock Your Phone Using Face or Fingerprint Scan https://thehackernews.com/2019/01/phone-fingerprint-unlock.html [Let me add a few words here: Although I trust the site, they are not legal experts. This is one ruling in California. It is a fact that you cannot be forced to open your phone if secured with the less secure password/code. Nothing that is in your head. You can up until this point be forced to open your phone if you use the more secure physical methods like finger prints. This has been confirmed by many legal scholars. So outside of California, it may still be an issue. Lastly, I am currently training in cyber forensics and it has included the requirements for a search warrant, as we find evidence used in courts. Search warrants must be very specific about what they expect to find. Note I have bolded above how the judge found that the warrant was not limited to a person or device. They cannot have me open your phone because I happen to be in the room with you or your device. That said, this is an important call made by this judge and I applaud it. I do not use fingerprint or facial recognition as I can be forced to open my phone, I use the less secure options so that I cannot be forced to open it.]

    CSS stylesheet not working properly

    Thanks, after all it was the <style> included in the stylesheet, like you said. Solved.

    CSS stylesheet not working properly

    your style sheet should not have this syntax: <style> </style> just do it like this: body { background: url("images/background-forum.jpg"); } and include it in your html head: <link href="pathTo/style.css" media="all" rel="stylesheet" type="text/css">

    CSS stylesheet not working properly

    I mean that with HTML code it works on the index file, the problem is when I try to set a background image from a stylesheet (img 1), it doesn't. The path seems ok to me (img 2).

    CSS stylesheet not working properly

    The above is not CSS. The reason the CSS is not working, is simply small errors in your code. Just Google 'CSS background image', and you are sure find many examples. Stef

    Java BigDecimal

    actually I think I've solved it: BigDecimal a00 = new BigDecimal(a[0][0]); BigDecimal a01 = new BigDecimal(a[0][1]); BigDecimal a02 = new BigDecimal(a[0][2]); BigDecimal a10 = new BigDecimal(a[1][0]); BigDecimal a11 = new BigDecimal(a[1][1]); BigDecimal a12 = new BigDecimal(a[1][2]); BigDecimal a20 = new BigDecimal(a[2][0]); BigDecimal a21 = new BigDecimal(a[2][1]); BigDecimal a22 = new BigDecimal(a[2][2]); BigDecimal a00a11a22 = new BigDecimal("0.0"); BigDecimal a01a12a20 = new BigDecimal("0.0"); BigDecimal a02a10a21 = new BigDecimal("0.0"); BigDecimal a20a11a02 = new BigDecimal("0.0"); BigDecimal a21a12a00 = new BigDecimal("0.0"); BigDecimal a22a10a01 = new BigDecimal("0.0"); BigDecimal bigDecimalDeterminantMinuend = new BigDecimal("0.0"); BigDecimal bigDecimalDeterminantSubtrahend = new BigDecimal("0.0"); a00a11a22 = a00.multiply(a11).multiply(a22); a01a12a20 = a01.multiply(a12).multiply(a20); a02a10a21 = a02.multiply(a10).multiply(a21); bigDecimalDeterminantMinuend = a00a11a22.add(a01a12a20).add(a02a10a21); a20a11a02 = a20.multiply(a11).multiply(a02); a21a12a00 = a21.multiply(a12).multiply(a00); a22a10a01 = a22.multiply(a10).multiply(a01); bigDecimalDeterminantSubtrahend = a20a11a02.add(a21a12a00).add(a22a10a01);

    CSS stylesheet not working properly

    Hello everybody! I use > background: url("images/background-forum.jpg"); < inside the body of the css stylesheet, but no background image is added, but when I do this in HTML > <body background="images/background-forum.jpg"> < it works, the structure.css is in the same folder as index.html and the one with all the images called " images ". I use sublime text 3, someone can help me out?

    Java BigDecimal

    anyone know how to multiply multiple BigDecimals? not like this example: BigDecimal subTotal, taxRate, tax, total; subTotal = new BigDecimal("32.50"); taxRate = new BigDecimal("0.05"); tax = subTotal.multiply(taxRate); total = subTotal.add(tax); I need to multiple more than two numbers and also do addition. This is the line i'm trying to convert to BigDecimals: double aDeterminantMinuend = (a[0][0] * a[1][1] * a[2][2]) + (a[0][1] * a[1][2] * a[2][0]) + (a[0][2] * a[1][0] * a[2][1]); as you can see those are doubles in an array that i'm doing my arithmetic to. so I've prepped them like: BigDecimal a00 = new BigDecimal(a[0][0]); BigDecimal a01 = new BigDecimal(a[0][1]); BigDecimal a02 = new BigDecimal(a[0][2]); BigDecimal a10 = new BigDecimal(a[1][0]); BigDecimal a11 = new BigDecimal(a[1][1]); BigDecimal a12 = new BigDecimal(a[1][2]); BigDecimal a20 = new BigDecimal(a[2][0]); BigDecimal a21 = new BigDecimal(a[2][1]); BigDecimal a22 = new BigDecimal(a[2][2]); so now I need to do the BigDecimal arithmetic to them, but the only examples i can find are like the one posted above. Just two BigDecimals multiplied together. i've tried embedding multiple calls the multiple() method, but that doesnt work. I'm thinking the only way to do it is to make new BigDecimals for each step of the arithmetic, but surely theres a better, neater way?

    IWD - HTML Ch4.8 - Problem with code??

    Hi Stef I solved the problem. The tab in Sublime Text where I was editing the my_friends.html code was not affecting the code in the sub_pages folder for some reason. When I checked the source code from the web page itself the ../ was not present even though it was in the code editor. Once I closed the tab and dragged it back into Sublime Text from the sub_pages folder it all began to work fine. Thanks for your help. Rich

    IWD - HTML Ch4.8 - Problem with code??

    Hi Stef Thanks for the quick reply. The my_friends.html file is in the folder 'sub_pages' which is a sub-directory of where index.html is. I had all the links working fine when the pages were all in the same directory. I even have the Friends link in the index.html page linking to the friends.html page in the sub-pages folder without any issues so I think the file/folder structure is correct. I just cannot get the link to work going back in the other direction i.e. from friends.html (in the sub_pages folder) back to index.html in the main folder one directory above. The directories are set up exactly as shown in the tutorial video (I think - unless I am missing something)? Thanks Rich

    IWD - HTML Ch4.8 - Problem with code??

    Hi Rich, Paths are one of the big hurdles in learning web coding. So don't let it get to you. Suggestion: Based on what I see in your code and directory screenshot, you are simply not placing your files in the proper directories. So, in your code, you are telling the web browser with this code: ../ ... That the index page is in a directory above the current page. So place your friends.html page in a sub directory and be sure you index page is above that. To test this out and to learn, first get your links working where all your pages are in the same directory. Stef
  25. Hi I am currently working through the IWD course. I am on Chapter 4 part 8 (Paths). I have followed the instructions exactly but I cannot get the ../ part of the code to navigate up a directory when attempting to link back to the index.html page. I have saved the code in Sublime Text and refreshed the page in the browser but all I get is the 'Your file was not found' page. The link to the Friends page from the Index page works fine but not the other way around. I have attached a screenshot containing the code and the file structure. The my_friends.html file is in the sub_pages folder. Any help much appreciated, it was all going very smoothly until this. Thanks Rich
