Test innode
Mocha is a JavaScript test framework for Node.js and browsers that allows for BDD, TDD, and QUnit-style testing with features like asynchronous support, hooks, and skipping/focusing tests. Should.js is an assertion library that keeps test code clean and error messages helpful through expressive matchers. Sinon.js is a standalone test spy, stub, and mock library with no dependencies that works with any testing framework and provides features like spies, stubs, fakes, and assertions. Continuous integration tools like Drone, Travis CI, and Codeship automate running tests and building apps.
如何「畫圖」寫測試 - RxJS Marble Test
This document discusses RxJS marble testing. It provides an overview of Observables, Schedulers, and the TestScheduler. The TestScheduler allows testing asynchronous code by virtualizing time, mocking Observables with marble diagrams, and asserting expected emissions. Examples demonstrate creating cold Observables, time, and testing an Epic that uses delay with the redux-observable-test-helper. Marble testing makes asynchronous code more testable.
Design & Performance - Steve Souders at Fastly Altitude 2015
Fastly Altitude - June 25, 2015. Chief SpeedCurver Steve Souders explains how design and web performance are more interconnected than ever before. Users want a fast website with a rich design, but sometimes the interplay between design and performance feels like a fixed sum game: one side's gain is the other side's loss. Design and performance are indeed connected, but it's more like the yin and yang. They aren't opposing forces, but instead complement each other. Bringing these processes together produces experiences that are rich and fast.
Video from the talk: http://fastly.us/Altitude2015_Design-Performance
Steve's bio: Steve Souders is a co-founder at SpeedCurve, where he develops web performance services. His book, High Performance Web Sites, explains his best practices for performance; it was #1 in Amazon's Computer and Internet bestsellers. His follow-up book, Even Faster Web Sites, provides performance tips for today's Web 2.0 applications. Steve is the creator of many performance tools and services including YSlow, the HTTP Archive, Cuzillion, Jdrop, SpriteMe, ControlJS, and Browserscope. He serves as co-chair of Velocity, the web performance and operations conference from O'Reilly, and is co-founder of the Firebug Working Group.
Google App Engine Developer - Day4
This document summarizes how to connect to Cloud SQL from App Engine using Java. It discusses creating a Cloud SQL instance and bucket, uploading files to the bucket, and connecting to the database using JDBC. The key steps are to use the Google Cloud SQL JDBC connector and connection string, handling both local testing and production environments. Sample code shows querying the database using prepared statements once a connection is established.
Cassandra Summit EU 2014 Lightning talk - Paging (no animation)
This document discusses streaming and paging data from Apache Cassandra using observables. It introduces the speaker as an evangelist for Cassandra and describes how server-side paging and combining result sets with observables allows efficient streaming of large result sets without blocking or out of memory errors. Code examples are provided showing how to create an observable from a Cassandra query result set and subscribe to stream result rows.
Java. Explicit and Implicit Wait. Testing Ajax Applications
This document provides information on explicit and implicit waits in Selenium. It discusses the differences between explicit and implicit waits, provides code examples for each, and covers related topics like WebDriverWait and ExpectedConditions. Key points include:
- Explicit waits are code defined waits for a certain condition, like using Thread.sleep(). Implicit waits set a default wait time for finding elements.
- WebDriverWait can be used with ExpectedConditions to wait for elements to meet a certain condition like being clickable.
- Implicit waits set a default timeout for finding elements across all searches during the WebDriver session.
- There are convenience methods like elementToBeClickable to avoid writing custom ExpectedCondition classes.
- Screenshots can be
Node.js 與 google cloud storage
The document discusses Node.js and Google Cloud Storage. It covers topics like using OAuth2 to authenticate with JSON Web Tokens and service accounts, uploading files via simple, multipart, and resumable upload methods, and managing file metadata, access control lists, versions, and directories without a true folder structure in Cloud Storage. The author reflects on lessons learned like ensuring proper permissions when accessing buckets and the value of sharing knowledge gained from experimenting with Google services.

Opportunities for Tiny House and EcoVillage Communities
An overview of market trends, building options, and funding scenarios for developers of tiny house communities and EcoVillages. (May 30, 2015 Workshop at White Lotus Eco Retreat, Stanardsville, VA, USA)
50 great reasons and creative examples for brands to use branded entertainmen...
Branded entertainment is not only "fun" brand content it's all the types of brand content that can satisfy the centers of interest of an audience on TV or on line : sports, music, films, ... It's not editorial content however it embodies the brand values and communicates on it's products.
1- Brands as fun destinations
Firstly, we're all used to seeing brands sponsoring entertainment as a means to get their logo and messaging in front of consumer eyeballs now brands are becoming destination sites and platforms for entertainment, in and of themselves.
2- Branded fun for new brand fans
Secondly, branded entertainment challenges brands to deliver a more enriching experience that consumers want yet communicate effectively what the brand values or the product benefits. Therefore it requires brands to create high quality branded contents, and not just sponsor an event, advertise within the programs, or create an ephemeral buzz.
3- Fun campaigns to promote fun contents
Brands investing in branded entertainment don‘t simply advertise on line. They use the tools that are available to best promote their content : paid media, owned media, earned media.
4- The new brand to fans relationship
Brands are able to develop an enduring direct-to-consumer relationship thanks to the quality content, however their potential fan base is much wider than their brand fans and they need to animate the extended fan community.
5- Live events for real time experiences
Communication enters a new era of real time marketing and brands come to life when people access their content all together at the same time and share their experience.
6- Data to spot fun insights on consumers
Trust me you are going to need it to do all the above !

Top Ten Web Defenses - DefCamp 2012
The document discusses defenses against SQL injection and cross-site scripting (XSS) attacks. It provides examples of query parameterization in different programming languages to prevent SQL injection and discusses contextual output encoding to prevent XSS attacks. It explains how to securely store passwords by using techniques like salting, hashing, and multiple iterations to make password cracking more difficult.
Metrics stack 2.0
Most metrics systems link timeseries to a string key, some add a few tags. They often lack information, use inconsistent formats and terminology, and are poorly organized. As the amount of people and software generating, processing, storing and visualizing metrics grows, this approach becomes very cumbersome and there is a lot to be gained from taking a step back and re-thinking metric identifiers and metadata.
Metrics 2.0 is a set of conventions around metrics: With barely any extra work metrics become self-describing and standardized. Compatibility between tools increases dramatically, dashboards can automatically convert information needs into graphs, graph renderers can present data more usefully, anomaly detection and aggregators can work more autonomously and avoid common mistakes. Result: less micromanaging of software and configuration, quicker results, more clarity. Less frustration and room for errors.
This talk will also cover the tools that turn this concept into production-ready reality:
Graph-Explorer is an application that integrates with Graphite. Enter an expression that represents an information need and it generates the corresponding graphs or alerting rules, automatically applying unit conversion, aggregation, processing, etc.
Statsdaemon is an aggregation daemon like Etsy's Statsd that expresses performed aggregations and statistical operations by updating the metrics tags, making sure that the metric metadata always corresponds to the data.

Main news related to the CCS TSI 2023 (2023/1695)
An English 🇬🇧 translation of a presentation to the speech I gave about the main changes brought by CCS TSI 2023 at the biggest Czech conference on Communications and signalling systems on Railways, which was held in Clarion Hotel Olomouc from 7th to 9th November 2023 (konferenceszt.cz). Attended by around 500 participants and 200 on-line followers.

Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

How we're using Firebase at Boiler Room
- 2. A custom chat for Boiler Room
- 8. Date mess-up thanks to using client local time
- 10. Moderators could delete single comments but we also needed a way to ban users..
- 13. var until = Date.now() + ($scope.ban.timeframe * 60 * 1000); commentsRef.root().child('banned_users/' + $scope.ban.uid).set(until);
- 15. child() expects a string argument.
- 16. "uid": { ".validate": "!root.child('banned_users').child(auth.id + '').exists()" } Validation Rules
- 17. var setBannedUsers = function(snap) { bannedUsers = snap.val(); }; var checkBannedUsers = function() { var time = Date.now(); for(bannedUser in bannedUsers) { if(bannedUsers[bannedUser] < time) { rootRef.child('banned_users/' + bannedUser).remove(); } } } rootRef.child('banned_users').on('value', setBannedUsers); setInterval(checkBannedUsers, 10000);
- 18. Thank you.
