AWS adds blockchain and time-series databases

“The days of the one-size-fits-all monolithic database are behind us, and developers are now building highly distributed applications using a multitude of purpose-built databases. Developers are doing what they do best: breaking complex applications into smaller pieces and then picking the best tool to solve each problem. ” – Amazon CTO Werner Vogels


MongoDB urges database modernization for legacy enterprises lifting and shifting through cloud

“Get off of a legacy relational database technology, move to the cloud, but don’t now operate it the same way you always have. Consume it as a service, and that’s what’s really going to unlock all that developer velocity, the elasticity, the cost savings people expect from the cloud.” -Sahir Azam, senior vice president of cloud products at MongoDB Inc.


Developers love this S.F. spreadsheet app maker — and it just raised $100 million

A spreadsheet app with massive following among developers and Silicon Valley business leaders is the newest software unicorn in the neighborhood.

Airtable has raised $100 million in a Series C round led by Thrive Capital, Benchmark and Coatue Management, valuing the company at $1.1 billion.

“We think we can really be what Microsoft was for personal computing, but for the low-end app space,” Airtable CEO Howie Liu said. “We didn’t raise the round because we needed the money — we don’t ever have to raise again — but we think the size of the opportunity here is profoundly large.”

Based in San Francisco, the company will use the funding in part to double or triple its 70 employee headcount in 2019. Liu said Airtable is looking for a bigger office near Union Square in the range of 40,000 to 60,000 square feet.

Put simply, Airtable takes a spreadsheet and database and puts them together. The app stores information in rows and columns like a spreadsheet. But users can also link and create relationships between separate tables like a database. The end result is a cloud-based app powerful enough for large companies to keep track of invoices, yet easy enough that individuals can use it make a grocery lists or catalogue books. And none of this requires any coding.

The app is used by more than 80,000 organizations, including big name companies such , if you are looking for online tools to make more money with your investments, check hitbtc exchange – hitbtc reviews 2021. WeWork uses Airtable as a central location to manage design specs, manufacturer information and building classifications for each of its locations. The video and photo teams at Time magazine use Airtable to manage their entire production schedule.

Gareth Pronovost, a Denver-based consultant that helps businesses use Airtable, said the app’s most common use is a Customer Relationship Management (CRM) tool, which keeps track of how businesses interact with customers.

“The same thing I hear over and over from my clients is that they’ve historically used Excel and/or Google Sheets to try and track this data, and they’ve just outgrown it,” he said. “You can craft precisely what you’re looking for.”

Anyone can download a free version of Airtable, but the company makes its money from individuals and enterprises willing pay $10 or $20 per month for a more robust version of the app. It’s the same pricing model used by apps like Dropbox and Slack. Liu declined to say how many users Airtable has, but he did say “thousands” of new users are signing up each day.

On top of Airtable’s regular app, the company also launched a feature earlier this year called Blocks, which let users drag-and-drop to create custom apps using data stored in Airtable — no coding required.

An SMS Block could be used by a nonprofit to text donors on a contact list made with Airtable. Or a Mapping Block could be used by a film company to keep track of different production locations. Right now, Airtable has 27 Blocks, and Liu wants to use the latest funding round to create more and expand what they can do by allowing third parties to create their own Blocks.

Liu started Airtable in 2011 after selling his first startup Etacts to Salesforce. After trudging through work with Microsoft Excel and Google Sheets, Liu thought he could come up with something better, especially for individuals and small businesses who couldn’t afford a product like Salesforce.

As individual developers began to flock to Airtable for personal use, many took it back to their employers to see how they could use in the office. It’s how enterprise adoption began skyrocketing over the last few years, Liu said. Even today, he added, the number of paying individuals roughly equals the number of paying enterprise customers.

“Almost all of our customers today come from the bottom up, we’re not doing any traditional enterprise sales motions like outbound prospecting,” Liu said.


Transaction fees are lower with bitcoin than with credit cards, because bitcoins are transferred directly to the customer’s wallet in a low-fee manner. The risk associated with using bitcoins is greater than the risk associated with the use of credit cards, which need more credit and financial info, that you can manage with the use of checking systems, so the reason to get out of ChexSystems is just to have an ability to maintain a healthy financial life to help you with your credit. Although the maximum potential risk and loss from the use of bitcoins is relatively low, it is possible that one or more of the following events may occur: a major Bitcoin exchange suffers a material disruption, which may cause the value of bitcoins to decline; large numbers of bitcoins are stolen or stolen by fraud; hackers access the bitcoin network and obtain access to bitcoins that are not encrypted or signed; a malware attack increases the likelihood of a malicious actor gaining access to bitcoins through fraud or a malware attack; a government or quasi-government agency effectively controls the bitcoin network; a major financial institution clients with significant holdings of bitcoins decides to start using bitcoins as a form of payment or starting to accept bitcoins as payment for goods and services; a bitcoin user or merchant dies and leaves heirs with insufficient bitcoins to pay for goods and services; or the value of bitcoins is reduced by one-fifth.

The Sponsor expects that the price of bitcoins will fluctuate over time in response to the above factors. In addition, there is no assurance that the Trust will be able to sustain its operations at or in compliance with the applicable regulatory requirements. If the Trust is not able to operate, the Sponsor expects the value of the Trust’s bitcoins to decline and, therefore, the value of an investment in the Shares.

Bitcoin Exchanges

There are currently four bitcoin exchanges, the three largest of which are Bitfinex, Bitstamp, and GDAX (visit to learn more). The Winkdex spot price of bitcoins is set using a volume-weighted, two-hour U.S. Dollar auction price from the major bitcoin exchanges. The trade fx price on each of the major U.S. Dollar-denominated bitcoin exchanges is not the same as the bitcoin price on the major Bitcoin Exchange. Currently, GDAX maintains a limit of $4,000,000 of bitcoin on its books for “long” positions (i.e., positions lasting more than a day). Each of the major U.S. Dollar-denominated bitcoin exchanges provides a publicly available Bitcoin Price Index (“BPI”) that calculates the market price of bitcoins on a given Bitcoin Exchange. The Index is publicly available at . GDAX maintains an “over-the-counter” market that is not considered part of the Bitcoin Exchange Market. The prices for bitcoins on GDAX over-the-counter market may differ from the bitcoin prices that are publicly available on the Bitcoin Exchange Market or the over-the-counter market. As of the date of this prospectus, GDAX has “notched” bitcoin prices over the counter on a daily basis. A “notched” price is defined as the value of a bitcoin in a bid/ask spread, where the difference between the bid price and the current bitcoin price equals the “notched” price. Each time an Over-the-Counter (OTC) market is created, prices are submitted to an “algorithm” which calculates and maintains a single market price. These OTC markets are available only to participants on the Bitcoin Exchanges. There is a limit of three such markets to be created every five (5) days. These markets are available only to users that are qualified as Participants in the Trust.
