How to check a blank bitcoin

I am willing to acquire bitcoins without transaction history (blank bitcoin) for a premium. How do I know that the bitcoins I receive do not have any previous transaction (except the one of extraction)? What evidence should the counterparty provide?

rstudio – R Markdown prints blank tables made with kable ()

Since I had to uninstall and reinstall R and R studio on my PC, I have trouble seeing the tables created with the kable () function in R Markdown.

When I run the block, it does not give me an error with the construction of the array, but in the notebook output, the elements of the array appear in white, with the exception of the titles, and with the exception. white background that appears by default, I do not see the contents of the table unless you select the text with the cursor. However, the table is correctly displayed in the viewer. When I knit HTML, the table also appears correctly with all visible elements. The only problem is that in the same output of the block, I can not correctly view the tables that I could see in the past.

This is problematic because I am a student and I have to be able to visualize correctly the result of my paintings to be able to continue working on my deliveries, because I have to use kable () yes or yes and it is too laborious to know the visualizer or to knit in HTML format to see if my table is done correctly.

I currently have R studio 1.2.5001 and R 3.6.1. I had the most recent version of R studio, but I do not remember the version of R that I had installed, but this one was not up to date and I was not there. had no problem viewing the tables in R Markdown.

I hope you can help me with my problem. Thank you very much.

User-centric design – What is the best blank page / cart message for ecommerce?

I'm looking for an ecommerce experience and I really think that showing a message that your shopping cart is empty is so boring. I think we need to show something more interactive for users.

What is the best message / empty basket page you have seen?
Do you have data / statistics on the conversion of an empty cart?

Look at what I have designed and give me your opinion as to which one should work better, please.

PS: My user is between 25 and 55 years old, mainly men and buys roofing materials. The sales process is not so short, not so impulsive and sometimes the user can add products to the cart, let them go and come back further, and not always the baskets always there (s & rsquo; they do not save).

Option 1) All empty and no value with some opacity, but looks like the real basket. Simulate where the products will be and show the button to go to the home page.

Option 2) All empty and no value with some opacity, but looks like the real basket. Funny picture not to be so boring.

Facebook displays a blank image and preview after sharing an HTTPS link from my website

My site previously was only HTTP. I've used this website to share public information with my friends. I like to post news that I want, then share it on Facebook and when I post a link (HTTP link, my website still being HTTP), it correctly pulls the og tags from my site.

Yesterday I just moved my site from HTTP to HTTPS by getting free CloudFlare SSL. I redirect my website to HTTPS and check for mixed content errors. There is not one. Now, when I share my posts (which is now HTTPS) on Facebook, the name of my website is displayed:

My friend says that I have the og tags currently defined on my site:

Weather Outlook — Updicity



















How can I fix that? Could this be a Facebook cache problem or something?

amazon – Obtaining AdSense approval on blank website homepages

I have a websiteand I plan to publish a growing number of projects (blogs / newsletters / newspapers / photo albums) on a back-end system – something like:

http://website.com/projects/( selected project )

As all projects are of different nature and theme – some are aimed at an adult audience – I do not really want to projects contain a lot of information. Maybe just a central logo or a few words explaining what this section is for if the site is intended – not what it contains.

My main plan is to direct people to projects via social media, forums, groups and offline media, once again emphasizing why I do not need it. projects contain any content.

The problem is … I really intend to use projects for a financial gain, and the best way is with something like AdSense and other networks for adult-focused work. However, registering with them means that you need to list a domain as the root of your website content, which is problematic for the following reasons:

  1. The root is a business site and nothing to do with my projects.

  2. the /projects/ the page is empty as shown above.

  3. If I recorded a brand new URL, there would always be a blank page as an index.

So, how can I register my site on these networks?

The same thing is happening for Amazon affiliates too!
