A New Engine Could Bring Back Supersonic Air-Travel

Slashdot - Fri, 12/14/2018 - 12:41
An anonymous reader shares a report (may be paywalled): Every morning, time once was, a giant roar from Heathrow Airport would announce the departure of flight BA001 to New York. The roar was caused by the injection into the aircraft's four afterburners of the fuel which provided the extra thrust that it needed to take off. Soon afterwards, the pilot lit the afterburners again -- this time to accelerate his charge beyond the speed of sound for the three-and-a-half hour trip to JFK. The plane was Concorde. Supersonic passenger travel came to an end in 2003. The crash three years earlier of a French Concorde had not helped, but the main reasons were wider. One was the aircraft's Rolls-Royce/Snecma Olympus engines, afterburners and all, which gobbled up too much fuel for its flights to be paying propositions. The second was the boom-causing shock wave it generated when travelling supersonically. That meant the overland sections of its route had to be flown below Mach 1. For the Olympus, an engine optimised for travel far beyond the sound barrier, this was commercial death. That, however, was then. And this is now. Materials are lighter and stronger. Aerodynamics and the physics of sonic booms are better understood. There is also a more realistic appreciation of the market. As a result, several groups of aircraft engineers are dipping their toes back into the supersonic pool. Some see potential for planes with about half Concorde's 100-seat capacity. Others plan to start even smaller, with business jets that carry around a dozen passengers. The chances of such aircraft getting airborne have recently increased substantially.

Epic Games' Free Cross-Platform Service Coming in 2019, Harness Announces New 24-7 Service Guard, Vivaldi Version 2.2 Released, KDE Applications 18.2 Are Out and Valve's Steam Link App for RPi Officially Available

Linux Journal - Fri, 12/14/2018 - 08:59

News briefs for December 14, 2018.

Epic Games recently announced it's working on a free cross-platform service for 2019: "Throughout 2019, we'll be launching a large set of cross-platform game services originally built for Fortnite, and battle-tested with 200,000,000 players across 7 platforms. These services will be free for all developers, and will be open to all engines, all platforms, and all stores. As a developer, you're free to choose mix-and-match solutions from Epic and others as you wish." Epic also noted that "all services will be operated in a privacy-friendly, GDPR-compliant manner".

Harness yesterday announced the release of 24x7 Service Guard, a new "Machine Learning-based capability that empowers and protects developers who practice Continuous Delivery". According to the press release, "With 24x7 Service Guard, engineering teams now have the equivalent of a dedicated bodyguard to watch all production services and observe the end user experience across all APM, monitoring, and log tools. When a service is impacted, 24x7 Service Guard can proactively roll back code changes automatically—the equivalent of a 'safety net' for production applications."

Vivaldi, the ultra-customizable browser with a do-not-track policy, released a new version yesterday. Version 2.2 "improves accessibility, navigation and media". The Vivaldi blog post notes that "the update introduces more unique ways to manage tabs, makes Access Keys easier to use, integrates Pop Out video, and makes the browser's toolbars more configurable."

FOSS Project Spotlight: Appaserver

Linux Journal - Fri, 12/14/2018 - 07:00
by Tim Riley

An introduction to an application server that allows you to build MySQL user interfaces without programming.

Assume you are tasked to write a browser-based, MySQL user interface for the table called CITY. CITY has two columns. The column names are city_name and state_code—each combined are the primary key.

Your user interface must enable users to execute the four main SQL operations: select, insert, update and delete. The main characteristics for each operation are:

  • The select operation needs an HTML prompt form to request a query. It also needs a where clause generator to select from CITY. After forking MySQL and retrieving the raw rows, it needs to translate them into an HTML table form.
  • The HTML table form needs to be editable, and user edits need to be translated into update statements.
  • Each resulting row following the execution of a query is a candidate for deletion.
  • The insert operation needs a blank form. It also needs to translate Apache's common gateway interface (CGI) into insert statements.

So, you might create the source file called city.c and type in all the required code. Of course, relational databases have relations. One city has many persons residing in it. Assume the PERSON table has the column names of full_name, street_address, city_name and state_code. full_name and street_address combined are the primary key (Figure 1).

Figure 1. Database Schema of Many Persons Residing in One City

Are you going to create the source file called person.c too? What about customer.c, inventory.c, order.c, ...?

Alternatively, you might create the source files called select.c, insert.c, update.c and delete.c. Then each of these modules would need as input:

  • A single table name.
  • The table's additional attributes.
  • The table's column names and additional attributes.
  • A recursive list of related tables.
  • Apache's CGI dictionary output.

The principle behind Appaserver is this multi-module approach. Appaserver stores table names in a table. Each table's column names and relations are also stored in tables. Taking the table-driven concept to the nth degree forms a database of a database. You can glean a detailed understanding of how the Appaserver database is modeled from https://appahost.com/appaserver_database_schema.pdf.

The Painful, Costly Journey of Returned Goods -- and How You End Up Purchasing Some of Them Again

Slashdot - Fri, 12/14/2018 - 05:00
Buyers return a huge number of packages they buy from Amazon and other e-commerce sites, so much so that retailers are sometimes left with little choice but to get rid of large swaths of inventory at a cost. Last year, customers in the U.S. returned about $351 billion worth of items that they had purchased from brick-and-mortar retailers and online stores, according to estimates by National Retail Federation. CNBC: There's a good chance that the $100 printer, the $300 wide-screen monitor, or the $170 router you recently bought from Amazon weren't supplied to the e-commerce giant by their original manufacturers. In fact, the order may have been fulfilled by someone like Casey Parris, who resells items that customers previously returned to retailers. Based in Florida, Parris spends about five hours each day visiting thrift stores and scanning auction and liquidation websites for interesting items, he told CNBC. Sometimes he finds auto parts, other times it's a pair of sneakers, and occasionally he purchases printer cartridges -- all with the goal of reselling them. Walter Blake, who lives in Michigan, does the same. For years, he's been selling electronic items on Amazon that he acquires from a network of places. Blake and Parris are part of a growing cottage industry where dealers acquire discarded items at very low prices, only to resell some of them back on Amazon and eBay at a premium.
