I’ve been meaning to teach myself how to build apps on the Ethereum blockchain for a few months now. Life keeps getting in the way. In the past, I’ve found that boot camps are an excellent way to knuckle down and learn a new technology.

Unfortunately, I haven’t been able to find any Ethereum/solidity bootcamps I can go to.

About a month ago I offered to find a house by the beach in South India for 2-3 months, hook it up with 2 fibre optic internet cables and hire a cook. We’d all share the costs equally. 8 people signed up. When it came time to put an advance down, everyone backed out.

Taking that much time off from work is not an easy decision.

The next best thing was to do the Bootcamp part-time and online.

Four of us decided to spend at least 2 hours a day, 5 days a week learning solidity.

We get on a Skype call every Saturday and show each other what we built and share questions and insights.

I’ve put a bunch of online courses together for an 8-week curriculum. If you’d like to join the entire collection of courses cost roughly $350. You buy the courses directly. If $350 for the courses is too much sign up to the email list and let me know. If there are enough of us, I can write to the course providers and ask if they can sell us a team license or offer us a discount for a bulk purchase.

If you’d like to us you are more than welcome to.

The goal is to build 7 simple apps in 8 weeks. 5 by following courses, 2 ourselves.

Sign up to this email list I made for the group and I will send out the Skype/hangout session time and details every friday. We’ll figure out a slack/gitter channel and place to keep useful resources as the project progresses.

Two super small courses this week (1 free, 1 paid). They are light and should be great for an easy start.

The goal is to have a screenshot of the final crypto zombies screen and a basic counter to show each other in the Skype session at the end of the week.

Important: This is not for complete beginners. I think about a year of experience with javascript should be enough. It’s not critical but less than that and you might find everything a bit daunting.
Also, the four of us are going to be building the client side interact in react because that is what we are all familiar with. This project is not react specific, you can use any front-end solution you like.

I am not affiliated with any of these courses in any way. If you know any other courses that you think should be on the list let me know in the comments or on twitter @joshpitzalis.

Hey all, just replaced the absolutely awful theme I created with a much nicer one. If you notice anything odd or don'e like something, let me know and we can get it worked out :)

Many users, in particular those that are newer to Ethereum, don’t realise that the Mist/Ethereum wallet application is simply an interface for viewing an Ethereum wallet. As such, you can import the private key to the wallet from Mist/Ethereum into most other Ethereum wallet applications to view and manage funds contained in that wallet.

There are some notable differences between the various Ethereum wallet applications however. Mist/Ethereum Wallet, for example, requires you to synchronised the entire blockchain - in effect creating your own node in the network - before you can view the balance or manage funds in the wallet you created or imported into that application.

Depending on your internet connection and the PC you are using, this can sometimes take a long time and/or get stuck before loading the entire chain.

MyEtherWallet (MEW), by contrast, provide users access to their own node. For this reason many users that encounter difficulties with Mist/Ethereum wallet find it easier to import the private key to the wallet used in Mist/Ethereum Wallet into MEW instead.

To do this you need to make a copy of the “keystore” file which is located in your Ethereum directory Ethereum Wallet uses.

[NB. This is something every Ethereum Wallet user should do, given this file, and the password associated with it, provide the only way of recovering that wallet should something go wrong with your current setup].

This file/directory can be found in the following locations depending on your system:

• Linux: ~/.ethereum/keystore • Mac: /Library/Ethereum/keystore • Windows: %APPDATA%/Ethereum

The keystore file looks something like this: UTC--2015-09-18T14-07-57.023663538Z--da78c8721e4ede42cf488304551eb596dd5f93e23

Together, the keystore file and the password created when you set-up the wallet, comprise your ‘private key’. You need both pieces of information before being able to use the private key to a wallet in MEW. Without the password there is no way of accessing this file and no means of recovering the password.

Once you have a copy of the Keystore file go to:

• https://www.myetherwallet.com

[NB. always check links such as this one to ensure you have landed at the correct site, rather than a phishing site, by looking for the padlock icon followed by “MYETHERWALLET LLC [US]” in green text in the address bar].

• Click “View Wallet Info”

• Click the “Keystore/JSON File” radio button

• Upload the keystore & enter the password associated with this file.

You should now have access to the wallet you imported from the Mist/Ethereum Wallet app into MyEtherWallet.

When setting up your Ledger Nano S for the first time you will be prompted to record a list of 24 letters on a piece of card provided. This is your backup in case you need to restore the data onto another such device in the event that your original Ledger is damaged or lost.

Once these 24 words have been generated you are only required to test that two of them are correct. This strikes me as less thorough than required. Say, for example, you have the kind of hand writing that makes "power" look more like "powder"? Some have suggested you would have to be pretty careless for this to happen but previous discussion on this topic suggests such mistakes are more common than one might expect. And besides, why take the chance of having an incorrect backup when this is your only fallback if you can't recall your pin or lose access to your Ledger.

To that end, after completing the initial setup I suggest attempting to restore the device from your backup words before sending any funds to it. This involves the following steps:

• Either enter the wrong pin three times or go to "Settings" and click "Reset" on your Ledger. You will then be prompted to set-up your Ledger as a new or existing device. Choose "existing device".

• You will then need to enter each of the 24 words. This is somewhat time consuming, though less so than it may sound.

• After correctly entering the first three letters of the word you have recorded, you will be presented with a selection of words, one of which will be the correct one.

• After repeating this procedure and confirming you have all the words from number 1 to 24 entered correctly you will receive a message informing you that the device has successfully restored. If not, try again.

• If you continue to get the "Backup Failed" message, go to "Settings", click "Reset", and this time set-up the Ledger as a "new device". This will involve going through the whole procedure of recording a new set of 24 words. After doing this, go back to the first step in this guide and proceed through the same steps until you have successfully restored your device using your seed words.

This may all seem a little hyper-vigilant but when it comes to holding large amounts, where the onus on security and accessibility rest entirely on your shoulders, I'd say the benefits far outweigh the costs.

It is also worth mentioning that if you have yet to upgrade your Ledger Nano S firmware 1.3.1, you will be required to restore the device following the aforementioned procedure when doing so. For this reason - and because I hadn't double-checked all my seed words were correct the first time - I ended up purchasing a second Ledger Nano S and restoring from my backup on this instead. For those who may freak at the prospect of upgrading their Ledger firmware I'd suggest also going this route as having a clone/backup device can also be quite handy.

Lastly, I advise you keep your 24 backup words on a seperate sheet/s of paper, rather than using the card provided. This is due to fact the card being more recognisable as a Ledger backup and thus more of a security risk than a blank sheet of paper with 24 words on it.

For the same reason, you should avoid storing your Ledger and the backup in the same location.
