The Rise and Fall of the Cheat Code 178

Posted by Unknown Lamer from the iddqd dept.
An anonymous reader writes A new feature published this week takes a deep-dive look at the history of the cheat code and its various manifestations over the years, from manual 'pokes' on cassettes to pass phrases with their own dedicated menus — as well as their rise from simple debug tool in the early days of bedroom development to a marketing tactic when game magazines dominated in the 1990s, followed by dedicated strategy guides. Today's era of online play has all but done away with them, but the need for a level playing field isn't the only reason for their decline: as one veteran coder points out, why give away cheats for free when you can charge for them as in-app purchases? "Bigger publishers have now realized you can actually sell these things to players as DLC. Want that special gun? Think you can unlock it with a cheat code? Nope! You've got to give us some money first!"

Over 300,000 Servers Remain Vulnerable To Heartbleed 74

Posted by samzenpus from the protect-ya-neck dept.
An anonymous reader writes Even though it's been a couple months since the Heartbleed bug was discovered, many servers remain unpatched and vulnerable. "Two months ago, security experts and web users panicked when a Google engineer discovered a major bug — known as Heartbleed — that put over a million web servers at risk. The bug doesn't make the news much anymore, but that doesn't mean the problem's solved. Security researcher Robert David Graham has found that at least 309,197 servers are still vulnerable to the exploit. Immediately after the announcement, Graham found some 600,000 servers were exposed by Heartbleed. One month after the bug was announced, that number dropped down to 318,239. In the past month, however, only 9,042 of those servers have been patched to block Heartbleed. That's cause for concern, because it means that smaller sites aren't making the effort to implement a fix."

Teaching Creationism As Science Now Banned In Britain's Schools 649

Posted by Soulskill from the pi-is-exactly-3 dept.
sandbagger sends this news from io9: In what's being heralded as a secular triumph, the U.K. government has banned the teaching of creationism as science in all existing and future academies and free schools. The new clauses, which arrived with very little fanfare last week, state that the "requirement for every academy and free school to provide a broad and balanced curriculum in any case prevents the teaching of creationism as evidence based theory in any academy or free school." So, if an academy or free school teaches creationism as scientifically valid, it's breaking the funding agreement to provide a "broad and balanced curriculum." ... In addition to the new clauses, the UK government clarified the meaning of creationism, reminding everyone that it's a minority view even within the Church of England and the Catholic Church.

Emotional Contagion Spread Through Facebook 127

Posted by Soulskill from the your-opinions-are-my-opinions dept.
Daniel_Stuckey sends this quote from Motherboard: It hopefully doesn't come as a surprise that your friends shape who you are. But we tend to think of that on a micro level: If your close circle of friends tends to have tattoos, wear polo shirts, or say "chill" a lot, it's quite possible that you'll emulate them over time — and they'll emulate you too. But what happens on a macro scale, when your friend circle doesn't just include the dozen people you actually hang out with regularly, but also the hundreds or thousands of acquaintances you have online? All of those feeds may seem filled with frivolities from random people (and they are!) but that steady stream of life updates — photos, rants, slang — are probably shaping you more than you think. A massive Facebook study recently published in PNAS found solid evidence of so-called emotional contagion—emotional states spreading socially, like a virus made of emoji—on the social network.

4K Monitors: Not Now, But Soon 186

Posted by Soulskill from the wait-for-16K dept.
An anonymous reader writes 4K monitor prices have fallen into the range where mainstream consumers are starting to consider them for work and for play. There are enough models that we can compare and contrast, and figure out which are the best of the ones available. But this report at The Wirecutter makes the case that absent a pressing need for 8.29 million pixels, you should just wait before buying one. They say, "The current version of the HDMI specification (1.4a) can only output a 4096×2160 resolution at a refresh rate of 24 Hz or 3840×2160 at 30 Hz—the latter, half that of what we're used to on TVs and monitors. Connect up a 4K monitor at 30 Hz via HDMI and you'll see choppier animations and transitions in your OS. You might also encounter some visible motion stuttering during normal use, and you'll be locked to a maximum of 30 frames per second for your games—it's playable, but not that smooth. ... Most people don't own a system that's good enough for gaming on a 4K display—at least, not at highest-quality settings. You'll be better off if you just plan to surf the Web in 4K: Nvidia cards starting in the 600 series and AMD Radeon HD 6000 and 7000-series GPUs can handle 4K, as can systems built with integrated Intel HD 4000 graphics or AMD Trinity APUs. ... There's a light on the horizon. OS support will strengthen, connection types will be able to handle 4K displays sans digital tricks, and prices will drop as more 4K displays hit the market. By then, there will even be more digital content to play on a 4K display (if gaming or multitasking isn't your thing), and 4K monitors will even start to pull in fancier display technology like Nvidia's G-Sync for even smoother digital shootouts."

Huawei, Vodafone Test Out Hybrid System That Combines LTE and GSM 46

Posted by timothy from the they're-into-bonding dept.
alphadogg (971356) writes "In the hunt for more spectrum to speed up mobile networks, Vodafone and Huawei Technologies have successfully tested a technology that lets LTE and GSM share the same frequencies. The speed of future mobile networks will depend on the amount of spectrum mobile operators can get their hands on. The more they get, the wider the roads they can build. One thing they can do to get more space is to reuse frequencies that are currently used for older technologies such as GSM and 3G. But that isn't as easy as sounds, as operators still have a lot of voice and messaging traffic in those older networks. However, using a technology called GL DSS (GSM-LTE Dynamic Spectrum Sharing) Vodafone and Huawei have shown a way to allow GSM and LTE to coexist."

Book Review: Security Without Obscurity 51

Posted by samzenpus from the read-all-about-it dept.
benrothke (2577567) writes Having worked at the same consulting firm and also on a project with author J.J. Stapleton (full disclosure); I knew he was a really smart guy. In Security without Obscurity: A Guide to Confidentiality, Authentication and Integrity, Stapleton shows how broad his security knowledge is to the world. When it comes to the world of encryption and cryptography, Stapleton has had his hand in a lot of different cryptographic pies. He has been part of cryptographic accreditation committees for many different standard bodies across the globe. Keep reading for the rest of Ben's review.

How To Make Espresso In Space 192

Posted by timothy from the they-finally-saw-airplane-II dept.
In a story that's sure to bring to the surface the long-debunked myth of an over-elaborate NASA quest to create a pen to operate in space, Wired reports that the coffee situation aboard the International Space Station is about to improve: the station will be getting a 20kg, custom designed Lavazza espresso machine, to be delivered along with Italian astronaut Samantha Cristoforetti. Among other differences from terrestrial espresso machines: the resulting beverage must be pumped into a straw-friendly bag rather than a demitasse. I wonder if there could be some way to adapt a (much lighter) Aeropress for space purposes, as a backup.

Civilians Try to Lure an Abandoned NASA Spacecraft Back to Earth 53

Posted by timothy from the tractor-beams-are-the-missing-link dept.
A New York Times piece (as carried by the Pittsburgh Post-Gazette) outlines a fascinating project operating in unlikely circumstances for a quixotic goal. They want to control, and return to earth, the International Sun-Earth Explorer-3, launched in 1978 but which "appears to be in good working order." Engineer Dennis Wingo, along with like minded folks (of whom he says "We call ourselves techno-archaeologists") has established a business called Skycorp that "has its offices in the McDonald's that used to serve the Navy's Moffett air station, 15 minutes northwest of San Jose, Calif. After the base closed, NASA converted it to a research campus for small technology companies, academia and nonprofits. ... The race to revive the craft, ISEE-3, began in earnest in April. At the end of May, using the Arecibo Observatory radio telescope in Puerto Rico, the team succeeded in talking to the spacecraft, a moment Mr. Wingo described as "way cool." This made Skycorp the first private organization to command a spacecraft outside Earth orbit, he said. The most disheartening part: "No one has the full operating manual anymore, and the fragments are sometimes contradictory." The most exciting? "Despite the obstacles, progress has been steady, and Mr. Wingo said the team should be ready to fire the engines within weeks."

I was under the impression that while humans mostly cannot hear ultrasonic sounds, the existence of them can be perceived as a kind of "texture" to other sounds that we can hear. Removing these frequencies all together from all sounds sources can make stuff sounds more artificial.

The timbre of any sound is due to harmonics -- frequencies higher than the fundamental. MP3 and other lossy compression schemes do indeed remove some of the quieter harmonics. However, if the harmonics are outside the hearing range, well, then you can't hear them.

However, there may be nonlinear effects which convert some of the ultrasound to lower frequencies. Also, when a frequency exceeds the Nyquist limit (half the sampling rate), it is aliased to a frequency within the sampling range. (Hence "anti-aliasing", which is simply filtering out too high frequencies to prevent this effect.)

The official ISO 3166-1 2 letter code for the UK is GB though - Short for "United Kingdom of Great Britain and Northern Ireland".

"United" and "kingdom" aren't usually considered part of a country's name according to the ISO. Although it does seem a little odd that no exception was made in this case, since the United Staes of America is US.

In other words, UK = {GB, NI}. There's nothing wrong with metonymy (using a part when referring to the whole), but I think we can all agree that NI is a lot (as in "Sir *lot") is more appropriate for the country known for all the knights.
