The Flippening & How I Learned To Stop Lovingbitcoin

The Flippening & How I Learned To Stop Lovingbitcoin

The Flippening & How I Learned to Stop LovingBitcoin A scientific man ought to have no wishes, no affections, a mere heart of stone. CharlesDarwin The feelings of love and affection for a network protocol may seem a bit absurd to an outsider of the cryptocurrency space, but not to those who have been in the industry for years, in fact, its rather common place. The phenomena of techno-worship did not start with Bitcoin, but surely there have been few loves as devout and developed as the one between Bitcoiners and Bitcoin. The evolution of this fetish or worship did not happen quickly, but rather, as with most strong loves, years of interaction provided the fertile grounds for devotion. I must admit, so as to provide full disclosure I did once love Bitcoin It takes time to be reflective and to gain value from our past experiences. Many of you whom this article finds will not receive it pleasantly, but in fact, it may be received rather threateningly. I cannot blame you for this, as I too know what its like to be blinded by love. Please know that my intentions are friendly but I will not be the friend who enables. If you have been actively watching Bitcoin since the early days 2008 being the start of it all then you know that this was the launch of a new era. Conceived amidst the chaos of the global financial crisis and with such poetic timing, some might call it destiny. On January 3, 2009 the genesis block was generated and thus birth of the first digital talisman. Andreas Antonopoulos, the de facto spokesperson/preacher of Bitcoin, started his involvement in early 2012, quitting all other work to research and promote Bitcoin full time. Antonopoulos deserves massive respect, as he is the spring board from which Bitcoin has jumped. He has spread awareness of the value an Continue reading >>

Paging One-to-many Results In Sql

Paging One-to-many Results In Sql

Pagination in databases, the division of query results into manageable subsets, is oftenimplemented in terms of SQL constructs like LIMIT or FETCH FIRST, and OFFSET. Thisworks well when the result is compromised of one-to-one relationships. On the other hand,hypothesise what happens if the relationship is a one-to-many as in the following DDL [1]: An author can write n books as expressed in the foreign key constraint declaredon Books authorId column. A SELECT * FROM statement joining the two tables by the authors ID will produce a row foreach book the author has written. This means that if you have 3 authors and each one has authored 3 books,the query will return 9 rows: An attempt at formulating a query that sorts the result by author name and fetchesthe results first page, were the page can have at most 2 authors, might go like this: Perhaps to ones surprise, the above SELECT statement, with a LIMIT of 2 and an OFFSET of 0, will only return booksauthored by Antonopoulos: The books authored by Chomsky as well as Antonopouloss book, Mastering Ethereum,werent included in the result because its the many-side of the relationship (i.e., books)which is paginated as opposed to the one-side (i.e., authors). Paging the one-sideof a one-to-many relationship isnt a trivial problem to solve in pure SQL withoutre-writing part of the query as a sub-select: In practice, I find it inconvenient to formulate a query in this way in order to accommodatepagination. It doesnt lend itself easily to runtime string manipulation, andtherefore, automating paging, so that the developer isnt forced to think about limits/offsetsevery time he writes a query, is harder. Most popular vendor DBMSs offer window functions for performing calculations over ranges of rows. One suchfunction is DENSE_RANK. T Continue reading >>

Parity's $280m Ethereum Wallet Freeze Was No Accident: It Was A Hack, Claims Angry Upstart

Parity's $280m Ethereum Wallet Freeze Was No Accident: It Was A Hack, Claims Angry Upstart

A cryptocurrency collector who was locked out of his $1m Ethereum multi-signature wallet this week by a catastrophic bug in Parity's software has claimed the blunder was not an accident it was "deliberate and fraudulent." On Tuesday, Parity confessed all of its multi-signature Ethereum wallets which each require multiple people to sign-off transactions created since July 20 were "accidentally" frozen, quite possibly permanently locking folks out of their cyber-cash collections. The digital money stores contained an estimated $280m of Ethereum; 1 ETH coin is worth about $304 right now. The wallet developer blamed a single user who, apparently, inadvertently triggered a software flaw that brought the shutters down on roughly 70 crypto-purses worldwide. That user, known as devops199 on GitHub although has since deleted their account, claimed they created a buggy wallet and tried to delete it. Thanks to a programming blunder in Parity's code, that act locked down all wallets created after July 20, when Parity updated the multi-signature wallet software following a $30m robbery . Parity calamity! Wallet code bug destroys $280 MEEELLION in Ethereum One of those now-frozen Ethereum wallets belongs to Cappasity, a startup an online marketplace for AR and VR 3D models. It says it had 3,264 ETH in the knackered Parity money store, worth about $1m at current prices, and isn't likely to get the funds back any time soon. Cappasity amassed the Ethereum from punters buying ARtokens, which can be exchanged for designs when the souk launches later this year. The biz still has access to the Bitcoins it received for ARtokens. Now Cappasity has alleged the wallet freeze was no accident: someone deliberately triggered the mass lock down, we're told, and there's evidence to prove it. By stu Continue reading >>

Mastering Ethereum Nick Weisser

Mastering Ethereum Nick Weisser

Last year in October 300 people including myself enjoyed an amazing talk byAndreas M. Antonopoulos at the Bitcoin Meetup Switzerland at Glockenhof in Zrich. Now I understand why 300 came to hear #blockchain author and philosopher @aantonop speak about freedom of speach and finances #bitcoin pic.twitter.com/oCfEzPzlra Nick Weisser (@nickweisser) October 26, 2016 Before his main talk he publicly announced Mastering Ethereum, a book for blockchain developers (75% about smart contracts) co-authored by Ethereum co-founder Gavin Woods. The print edition is supposed to be released inFebruary 2018. You can also check out the current state of the book on Github .On the cover of the book will be bees, an analogy for a decentralized organism. Mastering Bitcoin ( Github , OReilly ) had ants on the cover. It was the first time OReilly put insects on a cover. The purpose of ants was the simple idea of a superorganism that has emergent intelligence from the collaboration of very simple nodes. On his YouTube Andreas just published an interview by Stephan Nilsson, founder of Norway Bitcoin and Blockchain Association which took place at the Kasbah Hub on April 27, 2017 in Oslo, Norway. Heres my favorite quote from the interview and after that the video itself. The really interesting applications, those that are truly disruptive, truly out of the norm of what we do today on the Internet, that if you try to present them to an investor or regulator or a government agent theyre horrified, thats a good test. If what youre trying to do horrifies investors thats probably about just disruptive enough to be a meaningful application. And if theres smiles all around in a conservative board of investors guess what its not disruptive. 0:49 What are better ways to spread knowledge about Bitcoin and b Continue reading >>

How To Get Started: Your First Dapp, Under One Hour.

As of 10-dec-14 this tutorial is no longer up to date with the latest POC 7 feature set - please checkout the updated tutorials starting with this one This tutorial is the result of many days of studying best practices on how to leverage what's available on Ethereum now, and making the technology available to users today, several months away from the network go live date (March 2015). For this reason, keep in mind development practices are likely to change heavily throughout the next few months, and the below is in no way indicative of what you should expect from the finished product. I have also kept a very narrow focus and omitted much information. For more advanced documents please instead refer to 'further reading' at the bottom of this page. And now, onwards to a decentralized web! Please join us on IRC if you have questions! Ethereum enables the decentralized web, referred to as 'web 3'. What makes it different from web 2 is that on Ethereum, there are no webservers, and therefore no middlemen to take commissions, steal your data or offer it to the NSA, and of course nothing to DDoS. A dapp ('decentralized app') consists of two parts: a frontend, written in HTML or QML, and a backend (think of it as the 'database' for your frontend). We'll focus here on an HTML dapp. Good news: if you like bootstrap, or any other framework, you can continue using them, as the frontend of dapps have full network access, and CDNs are accessible. In fact, for all intent and purposes, developing a frontend for a dapp written HTML is the exact same as developing a website, and converting from web 2 to web 3 is in many cases trivial. Even better news: you get reactive programming baked in (which should please angular, meteor and derby fans), by simply using callback functions, and ther Continue reading >>

Downloaded Bitcoin Core From Github, Getting Configure Error: (configure: Error: Libdb_cxx Headers Missing)

Downloaded Bitcoin Core From Github, Getting Configure Error: (configure: Error: Libdb_cxx Headers Missing)

I'm following along with Andreas Antonopoulos Bitcoin book Mastering Bitcoin Chapter 3 (The Bitcoin client) I'm on a Mac and used homebrew to install the dependancies: brew install autoconf automake libtool boost miniupnpc openssl pkg-config protobuf qt Next step was ./autogen.sh which created some configuration scripts Now stuck at the configure script step. After running ./configure, everything looks good until the last line which is: configure: error: libdb_cxx headers missing How do I get libdb_cxx headers installed? Ah figured it out, I didn't completely finish reading all the instructions in the build-osx.md file #### Installing berkeley-db4 using HomebrewThe homebrew package for berkeley-db4 has been broken for some time. It will install without Java though.Running this command takes you into brew's interactive mode, which allows you to configure, make, and install by hand:```$ brew install -without-java ```These rest of these commands are run inside brew interactive mode:```/private/tmp/berkeley-db4-UGpd0O/db-4.8.30 $ cd ../private/tmp/berkeley-db4-UGpd0O $ db-4.8.30/dist/configure -- prefix=/usr/local/Cellar/berkeley-db4/4.8.30 --mandir=/usr/local/Cellar/berkeley-db4/4.8.30/share/man --enable-cxx/private/tmp/berkeley-db4-UGpd0O $ make/private/tmp/berkeley-db4-UGpd0O $ make install/private/tmp/berkeley-db4-UGpd0O $ exit``` After exiting, you'll get a warning that the install is keg-only, which means it wasn't symlinked to /usr/local. You don't need it to link it to build bitcoin, but if you want to, here's how: Continue reading >>

Flash - How To Embed A Video Into Github Readme.md? - Stack Overflow

Flash - How To Embed A Video Into Github Readme.md? - Stack Overflow

How to embed a video into GitHub README.md? Is it possible to embed a flash video into README.md on GitHub? It isn't showing up: The " Github Flavored Markdown " doesn't support this kind of feature for any page: An old support thread "Embed YouTube videos in markdown files" stated: With pages.github.io, yes, everywhere else, no. For instance: " HTML5 video in markdown " (August 2010): Is there any way to implement a HTML5 video into the README.markdown file? Not currently but we might be expanding what you can do with the READMEs in the future. In the meantime, you can do this with GitHub Pages and our Wikis. Benjamin Oakes confirms in the comments (May 2012): I sent in a support request. The response was that embedding videos is not supported. Those links seem to be broken; they take me to github.com/contact now. Does anyone have access to an archived version? I'm having a hard time getting it out of the Google Cache or the Wayback Machine. Benjamin Oakes May 2 '12 at 12:45 For what it's worth HTML5 video in wiki pages no longer seems to work. Benjamin Oakes May 2 '12 at 12:52 Is there a public issue somewhere that I could upvote? Will Feb 1 '14 at 10:26 @Will good question. I didn't see any. VonC Feb 1 '14 at 12:31 @hyipscript Not sure actually: that quotes comes from a 5-years old GitHub support thread (I have restored the link in the answer), from [ Chris Wanstrath -- defunkt]( github.com/defunkt ), one of the co-founders of GitHub. I don't have more details about that. VonC Oct 20 '15 at 20:09 See @aloisdg's answer , result is awesome, gifs are rendered on github's readme ;) If you need a quick fix just like I needed, you could trick the user into thinking the video is on the readme page with a picture. It sounds like an ad trick, it's not perfect, but it works a Continue reading >>

Ethereum In Practice - Quick Start Guide

Ethereum In Practice - Quick Start Guide

Ive found Ethereum documentation to be very thorough. And yet,Ive found it hard to understand how to approach Ethereum in practice - connect to the network, developand debug of a contract, deploy it and actually use it. This is what this post / guide / tutorial, and few coming posts, are about.Straight and to the point. This post certainly doesnt cover the theory which is already well explained in the official documentation, butrather focuses on how to get one up and running in, really, few minutes; because it is really that simple when you know how. And also when you know some theory as well. So, if you didnt read the official documentation, please, do so. Thispost assumes that at the very least one knows what Ethereum is and how it works and what an account, an EOA, a contract, gas and transactions are ,and finally would like to put it all to practice. There is a bare minimum of basic theory below otherwise. Here, in this post, following subject are covered: Run a private network, create a contract and deploy it to Homestad Ethereum network is decentralized. It means that there is no central server and what is called ethereumclient (like eth or geth for example) is really a part of the network when it is online. The network is allclients altogether. You know BitTorrent, right? So this is kind of the same, but better. So, step #1 - install the client. Again, there is no single client, there are multiple to chose from. Ethereum isdescribed in a specification, and multiple clients exist all implementing it. But really, as of the time of thiswriting, the most popular is geth, which is my choice as well, and which is the one used throughout this post in theexamples. Install instructions depend on the OS, so Im just pointing to geth GitHub repository . If you see the geth Continue reading >>

Yung Chou Joins @cloudexpo Ny Faculty | @azure #serverless #devops #jenkins #github #docker

DXWorldEXPO LLC announced today that Yung Chou joined the faculty of CloudEXPO's "10-Year Anniversary Event" which will take place on November 11-13, 2018 in New York City. Yung Chou is a Principal Cloud Architect at BlueMetal, a division of Insight. In his IT career, he has worked closely with customers and communities in various capacities including application development, technical support, solution sales, IT management and technology evangelism. Recently he has focused on hybrid cloud, IaaS solutions and emerging cloud technologies with strong interests in containers, IoT and Machine Learning. From Zero to a CI/CD Pipeline with Jenkins, Github, Docker and Azure in 60 minutes CI/CD is conceptually straightforward, yet often technically intricate to implement since it requires time and opportunities to develop intimate understanding on not only DevOps processes and operations, but likely product integrations with multiple platforms. This session intends to bridge the gap by offering an intense learning experience while witnessing the processes and operations to build from zero to a simple, yet functional CI/CD pipeline integrated with Jenkins, Github, Docker and Azure. Yung is an CloudEXPO faculty alumni member who presented highly popular sessions at CloudEXPO 2017 Silicon Valley, CloudEXPO 2016 Silicon Valley and CloudEXPO 2016 New York.

Mango: Git Completely Decentralised

Mango: Git Completely Decentralised

Software background. #blockchain, #ethereum & #hardware geek. Works on the payment card @meetblend. Git is a distributed (and soon decentralised) versioning or change tracking system, mostly used for managing software source code. It was created 11 years ago with decentralised development in mind. Every copy of a repository contains the entire history of changes. Development can be done entirely offline and without the need to wait for slow servers. Occasionally these offline repositories need to be synchronised if working together with others. This was a giant step after centralised solutions such as CVS and Subversion. Imagine a world where you had to wait up to 1030 seconds to compare or to make changes. That was Subversion in the era of 1 Mbps broadband. With Git it happens in a fraction of a second. This sounds pretty decentralised, doesnt it? It is, save one small issue copying and synchronising repositories. Git is flexible in this matter. It has a concept called remotes, which are remote endpoints for synchronisation and they can use a variety of protocols. The two most widely used ones are Git over SSH and Git over HTTP both are centralised. Initially users had to install their own server software, many times augmented with a web viewer called gitweb. An obvious evolutionary step was the appearance of services like Github, Gitorious/Gitlab, Bitbucket, etc. While these provide a wonderful service, they have the risk of single point of failure and censorship. Remember the denial of service attack against Github which rendered it unavailable for days? Remember that repositories can be removed based on copyright claims which might be invalid and reported by malicious actors, yet the onus to prove they are not infringing is on the creator of the repository? And tha Continue reading >>
