Unicode programming, with examples in C

Unicode programming, with examples in C

The Unicode standard and specifications describe the proper way to divide words and break lines, sort text, format numbers, display text in different directions, split/combine/reorder vowels South Asian languages, and determine when characters may look visually confusable. For instance ộ can be specified in five ways:

The numbers (written U+xxxx) for each abstract character and each combining symbol are called “codepoints.” The Unicode Transformation Formats (UTF) describe different ways to map between codepoints and code units.

Owning nothing is now a luxury, thanks to a number of subscription startups

Owning nothing is now a luxury, thanks to a number of subscription startups

Many young American urbanites have resigned themselves to a life of non-ownership, abandoning the dream of their parents and grandparents and great-grandparents before them, often out of financial necessity. While paying to borrow décor, clothing and offices is nothing new, the options have grown substantially in recent years. “We were raised to save and invest and buy a home and do all of these things,” said Miki Reynolds, 38, who pays a monthly fee for much of what she uses in her day-to-day life in Los Angeles.

Windows 10 Goes to Shell

Windows 10 Goes to Shell

If you have the creator update channel on Windows 10, though, there have been some recent improvements to the console and the Linux system that will eventually trickle down to the mainstream users. Then Windows turned the tables and became the operating system that could run MSDOS. Modern Windows still has an anemic MSDOS shell, but also PowerShell and the WSL bash shell.

Ordinary Security Cameras Could Keep an Eye on Rainfall

Ordinary Security Cameras Could Keep an Eye on Rainfall

The same security cameras used on seemingly every busy city block could also capture instantaneous measurements of rainfall intensity: the depth of rain that falls over a given time period. The new approach highlights the possibility of using existing CCTV networks to opportunistically measure rainfall intensity at high resolution and low cost. The authors suggest several paths for future research, including fine-tuning the raindrop identification algorithm to capture a wider range of raindrop phenomena, such as splashing.

NASA ‘Snoopy’ lunar module likely found 50 years after being jettisoned

NASA ‘Snoopy’ lunar module likely found 50 years after being jettisoned

NASA ‘Snoopy’ lunar module likely found 50 years after being jettisoned into trip to the Moon’s surface in July 1969 was preceded by a lot of preparatory missions — including Apollo 10, which involved a mock mission with everything but the actual landing. Astronauts Thomas Stafford and Eugene Cernan flew a lunar module, nicknamed “Snoopy” by the agency, nearly all the way to the Moon during Apollo 10, and then shot the module off into space once they’d completed their task. Apollo 10 was the fourth crewed mission in NASA’s Apollo Program, and it involved flying the lunar module to within 8.5 miles of the Moon’s surface — everything up to the last landing sequence where the module would perform its powered descent.

Direct to PCB InkJet Resist Printing (2006)

Direct to PCB InkJet Resist Printing (2006)

This page details the use of Epson^ InkJet printers with based inks to feed and directly print resist patterns to copper clad printed circuit board stock, ready for etching. And if you admit that a laminator is required for TT, given the prices for old C84^ or R220^ / R280^ printers and the Inks, direct to PCB InkJet printing is cheaper. The Epson InkJet printer use pizeo electric actuators in the print head (rather than the thermal method used by other brands) which allows for a wider range of ink types to be squirted out.

From Design Patterns to Category Theory (2017)

From Design Patterns to Category Theory (2017)

This makes the category theory concepts more specific, and less ambiguous, than design patterns. The coming article series is an exploration of this space:

I believe that learning about these universal abstractions is the next step in software design. Just like design patterns, you have to learn these things, but once you’ve learned them, you’ve learned something that transcends a particular software library, a particular framework, a particular programming language.

US Customs Database Of Traveler Photos Was Hacked And Stolen

US Customs Database Of Traveler Photos Was Hacked And Stolen

A subcontractor with the US Customs and Border Protection agency has suffered a data breach that exposed the photos of travelers traveling in and out of the United States. “This breach comes just as CBP seeks to expand its massive face recognition apparatus and collection of sensitive information from travelers, including license plate information and social media identifiers,” Neema Singh Guliani, a lawyer for the American Civil Liberties Union, said in a statement. Read CBP’s full statement below:
