Pokémon GO where to get holiday edition Pikachu


While these super cute Santa hat wearing Pikachu's are limited edition, they are not hard to find at all in any major cities and their town center landmarks. Keep in mind, Niantic uses Google Map API and the augmented reality game studio and its Ingres testers prefer artistic cultural centers. In San Francisco, it is easy to find holiday Christmas Pikachu from Pokémon GO at the performance arts center, symphony hall and city street art, city murals.

Some players have been saving extra Pidgey's to evolve during Christmas hoping for another bonus XP event when XP is automatically doubled even without a lucky egg.

Starting Christmas Day, special event, holiday pikachu will appear with much higher frequencies.

I have been playing Pokémon GO religiously. While I am still only at level 29. I have collected nearly all the Pokémon's in the pokedex only missing the legendary, regional (I got mr mime during my visit to the U.K.), and a couple of normal ones. 142 pokemons!

Machine Learning Concept - Cross Validation


  • Split data into chunks and subsequently use one part as testing and all others as training then switch to the next set. 

Machine Learning Concept - Supervised learning versus unsupervised learning


  • Unsupervised learning : data with no labels

Machine Learning Concepts - Classification versus Regression


  • Regression result is continuous
  • Classification result is discrete. Often encoded as numbers 0 to 1 to n in Sklearn. For example, having tumor is 1, not having tumor is 0

Pokemon Go tips to find Christmas Pikachu

Have you heard? Niantic the Pokemon Go team released limited edition Christmas Pikachu into the wild. These cute Pikachu's will not increase your Pokedex count but comes animated with a red mini Christmas hat. It's super cute and you can keep it in your pocket unless your transfer it away. Super cute! How do you get them? First you have to be playing the game. Next be sure to find the landmark spots in your city! No.1 tourist spots like the Eiffel Tower? A great idea! The city's architectural wonder library? Probably! Small town? No problem. Google (Niantic's map partner and previous parent company) really encourages appreciation for nature, arts and culture (many pokestops are arts, sculptures, landmarks and parks). Visit your local art houses - operas, symphony hall, giant wall murals. These are great places to find Christmas Pikachu's! In our city -  San Francisco, you can find it near the Civic Center performance arts center and Roots an art collective with a giant illustration mural on its side wall in SOMA.



From 0 to 1 Getting to your first sales on Shopify

You have set up your Shopify store, now what? It's time to get your first sales. How? While there are many opportunities to make sales online (the entire ecommerce market is huge), it's hard to get a slice of the big pie. At first. Here are a few tips for you. My store was featured in Christmas 2015 by UberRUSH (Uber postmate delivery) as a top 50 San Francisco small business store on the Shopify platform. www.at-lotus.com we sell high quality gifts that you often find in modern art museum stores!

Message to fellow sellers
Hi sellers, I just wrote this blog post. Please give me some feedback if you can. This is my advice to future sellers on Shopify platform. My store was featured on UberRUSH San Francisco as a top 50 small business seller. They featured my store last Christmas. 2 of my products reached the top 5 list!Among my tips mentioned in the above blog post, 1. generating noise on social media (using hashtags is very important) and 2. frequently checking and making discount offers in abandoned carts are two top tips that generate the most increase in sales. 

Generate some noise on Social Media

Social media is your grassroots marketing. Spread the word about your products on Twitter, Facebook, and Pinterest.

Enable store function on Social Media

Did you know that you can sell your products directly on Facebook, Pinterest, and Twitter? Shopify platform allows you to partner up with the big guys: run a Facebook store and enable Buyable pins in minutes. Don't forget Wanelo.

Spread the words to friends and family

I personally emailed my friends to ask them to consider my store for their Christmas shopping. I offered free gift wrapping, tax discount 10% off purchase, steep discount for slow items... They were doing me a favor but also gained value by getting free delivery, free advice and discounts. 

Use the #ShopifyPicks hashtag

Shopify's social media account will feature cool meaningful products on the Shopify platform. You can potentially get them to pay attention to you by using the #ShopifyPicks hashtag. Do not spam. Play nice.

Post to relevant forums

How did you find my blog post? You likely saw it in the Shopify forum just now. Special interest forums guarantees you perfectly targeted audience, who are also supportive and responsive. They are your most relevant audience. Selling  special skateboard and parts, better look for the best forums. You are guaranteed thousands of visitors and some great feedback if you ask.

Check abandoned carts often

Initially when your store needs time to mature and perfect, customers may visit your store and lose trust, interest or encounter difficulties. Use the Abandoned Cart feature to identify these potential customers, write them messages and offer a timely discount code.

Hustle and don't give up. 

I bought startup and entrepreneurship posters and posted them on my wall. I even wrote XyzName Hustles on my coffee mug. Whenever things get difficult, I get a mini boost from those entrepreneurship quotes.

I live and eat in the Silicon Valley. I write about everything Silicon Valley including startup, tech, learn to code, food and ecommerce.
