If you have decided you want to buy some zCash but don’t know how to go about doing it, here’s some help. It’s a little complicated to do as of now (May 2017) given that it’s a fairly new currency. There are many different ways to do this, what I have here is just one way that has worked for me.
Before you proceed, please pause to reflect. Cryptocurrencies are highly volatile and are not good investments. Think of the amount of ZEC that you plan to purchase – $100, $1k, $10k, more? Now imagine flushing that much cash down the toilet. How does it feel? If you’ll miss that cash and have better use for it then maybe you shouldn’t be buying ZEC with it. It’s best to only buy the amount that you are very comfortable losing entirely.
Step I: Create a virtual wallet
To hold your cryptocurrency, you need a virtual wallet. There are lots of options available for holding your currency. You can have wallets that are hosted by someone else or you can just physically own your virtual wallet on an electronic device you own. I have found JAXX to be the best wallet option out there. It’s available for every device/platform, syncs your wallets across them, is the most beautifully designed and is very reliable. JAXX is actually multiple wallets – one for each currency – you can choose which currencies you want to store in it. For our purpose here, you only need to initialize the ZEC wallet within JAXX.
- Go to JAXX
- Download JAXX for your device (iOS, Android, OS X, Windows etc).
- Launch JAXX after it is installed
- Select zCash (ZEC) as the wallet you want to initialize
- When it’s initialized, it will display a long gibberish string titled “your zCash(ZEC) wallet address). That is the unique address of your wallet that you will need this for step III.
- Right now your ZEC balance should be 0.00
Step II: Convert Cash (USD) into Bitcoin (BTC)
It’s very easy to exchange one cryptocurrency for another. The most friction is in converting regular Cash (USD) into the first cryptocurrency. Bitcoin (BTC) is the easiest cryptocurrency to work with. Assuming you don’t already have BTC lying around, the very first step is to convert some USD into BTC. There are several options but Coinbase is the easiest to use.
- Create an account on Coinbase
- Connect your bank account or credit card to it
- Get verified
- Go to Buy/Sell and Buy some BTC
Step III: Convert BTC to zCash (ZEC)
There are several exchanges that sell ZEC against various other currencies. I have tried a few and I found Changelly to be the easiest and most reliable way to do it.
- Go to Changelly
- Put in how much BTC you want to convert
- Put in your ZEC wallet address from your JAXX (from Step I in the beginning) where you want to receive the coins
- Send the BTC from your Coinbase wallet to the Changelly address
- Sit back and wait for the ZEC to arrive in your JAXX wallet
It can take time for cryptocurrencies to be transported. This is because “work” has to be done to verify the transfers by independent 3rd parties. But as long as you got the addresses right, it will work. You should now have some ZEC in your JAXX wallet. Please leave a comment if you have any questions, or leave any tips that might help others.
The next 10yrs are going to disrupt a lot more things than anyone can imagine. Design already needs to use AI to keep up with the exploding contexts and use cases they find themselves designing for. This is an example of how previously career jobs are getting replaced with neural networks that can learn all the knowledge and implement newer solutions. Read on to learn more about this experiment.
‘Infrastructure’ is something whose value becomes apparent only when it breaks down. The developed world only notices electricity, water, Internet when the supply/service is disrupted.
30yrs ago, very few people used computers or the Internet. Today, almost all work is influenced/ affected by digital manipulation of data. It’s infrastructural. Humans add most value doing tasks that technology hasn’t quite figured out yet.
Over the next 10 years, almost everyone’s work will begin to be impacted/influenced by Artificial Intelligence. As jobs get smartened, automated, and scaled, human tasks will continue to shift more into newer, higher abstractions that were practically unreachable in the past.This is an example of how User Interface and Interaction design has moved from tangible interfaces (e.g. physical buttons), to mutable digital interfaces and gestures (displays and touch screens) and now to a deeply integrated partnership with Artificial Intelligence. Designers have to be skilled in understanding contexts and distilling down use cases. But now, Artificial Intelligence is beginning to be the only scalable way to keep up with and design for abundantly complicated contexts of rapidly evolving technology and increasing levels of customization. Traditional UI design is already getting outdated.
When I studied engineering, the topic that I found the most philosophical value in was The Fourier Transform. It blew my mind as it took a complex, crazy, unruly world of waves in the time domain and transformed it into an orderly world of discrete frequencies and phases where they could be easily understood and manipulated. I remember realizing for the first time that most complex, emergent behavior in one dimension was something that could still be easily abstracted in another – a template for many problems we encounter in the world. This is the most accessible explanation of the Fourier Transform. Wish I had access to this when I was a student.
These are keys to my Lexus 4WD and my 3 bedroom apartment with a view of Mt Meru. I haven’t signed any papers so far. And hardly fronted any money.
- 8am – I text a guy that rents out cars.
- 10am – he shows up at my door, hands me the keys and leaves. I ask, when do I pay? He says you can pay me later.
- 5pm – I grab $$ from an ATM and pay him, along with a copy of my passport.
- 5pm I stop by to take a look at a house (along with many others)
- 8am (next day) I decide that’s the one I want
- 4pm I show up with my stuff and am handed a key to a just cleaned house. When do I pay you? He says: today I’m busy. Tomorrow I am going somewhere. How about the day after?
- So I will pay him in 2 days.
In Tanzania, trust is important. Relationships matter. The system doesn’t require you to distrust each other. Social reputation systems, and people’s reliance on them, remove the friction (and extra cost) associated with doing things more formally.
Western systems, however, are more universal. Not relying as much on social systems means there’s less biase, better exception handling and more scale.
As technology-mediated reputation systems get better, successfully avoiding all their traps and pitfalls, we can expect more Tanzania style personal, human service at western style scale and access.
I have had a cat for a few years and I use the following tools to help with cat maintenance:
Most cats are good at self regulating their meals. But many pet cats are often a little overweight. Some research shows that animals on slightly low calorie diets live longer. If you care to make sure you know how much your cat is eating and want to have better control on the diet and match it with it’s activity level, and you use dry kibbles anyway, then an automatic cat feeder is very useful. It also helps save a lot of time, there’s a more set routine for the cat, and you can be gone for a day or two and not worry about feeding the cat. I have tried lots of different feeders, and this one is the best so far.
Cat’s prefer drinking running water. They think stagnant, stationary water is unclean. Your cat is more likely to drink water from a fountain than from a dish. The leading cause of kidney issues in aging cats is caused due to not drinking enough water. So if you care about reducing the odds of kidney diseases in your cat, a pet fountain is a good investment. I have tried many different ones and found this one to be the best.
We attempted a late season climb of Mt Baker in Washington state. We were not experience enough to be just a two-person rope team – so that was kinda stupid. But we were quite risk averse in other ways. When we realized that the sun was beating quite hard and the snow bridges were beginning to melt, we decided it wasn’t safe to continue upwards. Given 80% of mountaineering accidents happen on the way down, we didn’t want to push our luck. Two other parties continued ascending and they did summit and also came back down safely. Different risk appetite, and luck.
Finally got to try Apple Pay and it’s the most frictionless payment I have ever made. It happened almost at the speed of thought.
- Sec 1: oh look, I can pay with Apple Pay
- Sec 2: double tap on home button (fingerprint read simultaneously)
- Sec 2: done
The fact that this was also the most secure payment I have ever made at a terminal is just icing on the cake. My credit card is hard-bound to my physical phone (my CC number is not associated with anything in the “cloud”). A unique one-time use string gets generated and transmitted each time I initiate a payment. Even if Whole Foods gets hacked, hackers won’t find any CC numbers, or usable auth codes in their database.
I switched to using OS X in 2007. I continued using OS X for personal use even while I worked for years at Microsoft.I had probably last started with a clean install back in 2011. Over the last 4-5 years I had installed and uninstalled many things. I had messed around with the shell. I had created symbolic links, implemented complicated workarounds to support the various edge cases that I needed to work with at different points in my life.
OS X has come a long way in the last 5yrs. The App Store was announced and I had started installing/updating my apps using it. Many tweaks and workarounds I had gotten used to became core features of the OS. Setting up development enviroments became a breeze with things like Docker and sophisticated package managers like Node/NPM.
I decided it was time to have a clean break and start over again. See, it’s easy to migrate/re-install and get back to where you were before. But I wanted to start clean for real. Make new decisions for my new workflows to reflect how both me and the tools I use had evolved.
I started on a Friday evening. Made a USB installer. Made a full backup of all my data files. I didn’t backup any configurations and settings on purpose. The thing that took the longest time was getting my pictures back up. I have a 1TB SSD drive (astronomical cost component on my laptop) which is mainly filled with pictures and videos.
So now I have a clean, wiped, brand new, fresh off the press copy of El Capitan with no baggage from the past. I install software as I need it and here’s where I am after a week.
So I checked in to my Lufthansa flight last night on my iPhone which ended with the boarding passes being added to my Wallet on my phone. This morning, when I arrived at the airport and swiped up on my Apple Watch screen, the boarding pass was already there!.When I swiped into it I could also have the QR code show up. I didn’t do anything to make it happen. The Apple Watch is just an extension of my phone, which is an extension of my life. Due things like these, I can just leave my phone in my bag and not have to take it out as often as I did before I got my Apple Watch.
I get asked a lot, is an Apple Watch worth it? It all depends on your use case and how much value you put on what it enables. In 2007 when the iPhone was launched, people asked the same question. 8 yrs later today, a lot of people have smartphones that never thought they ever would. In the same way, eventually humans do pay for increasing their capabilities and capacity (ever buy paper, or a notebook to write on?), and they pay for things that reduce friction in their lives (when was the last time you milked a cow?), and they pay for improving the quality of their lives (are shoes worth it?).
The Apple Watch is nice hardware, feels great, has a beautiful display, tracks my steps, my heart rate, my sleep, and it feels way more naturally integrated into my life than holding a phone – the trade-off being the depth of interaction.
