The problem: a toddler who is old enough to know how to operate the CD player and bossy enough to insist on doing it himself, but too young to understand that you should treat CDs with respect and care. So the typical CD in my household has probably spent some time scraping along the floor, or served as a Frisbee, or spent time in CD purgatory between the cushions of the couch. The amazing thing is they all still seem to play just fine.

How is this possible? The answer is one of the minor miracles of the digital age: error correction. For that matter, CD-ROMs and virtually any kind of digital storage would be impossible, because in a world where every scratch, scrape, and smudge meant lost data, the odds of actually finding a CD you could play, or a file you could open would be very small indeed. Irving S. CIRC operates on a couple of basic principles. First, extra data is added to the information recorded on the disk. As you probably know, an audio CD can hold up to 74 minutes of music.

What you may not know is that the real capacity is closer to minutes: 25 percent of the information recorded on a CD is actually there to help the CD player read the disk properly. Most of the rest are parity bits used for error correction. In simplest terms, a parity bit is either a one or a zero that is assigned to a short row of bits. Suppose you have a row of eight bits that looks like this: Add the individual ones and zeroes together and you get three.

Three is an odd number, so it gets the parity bit of one. If, on the other hand, the ones and zeroes added up to an even number, the parity bit would be a zero. Now, data on an audio CD are organized into blocks of 24 bytes. For every 24 bytes there are eight parity bytes, for a total of 32 bytes. That group is called a block.

When your CD player reads the data stream, it reads each little row of numbers in a block and adds them up. Got it? Now on to interleaving. If they did, that jelly smear would wreak havoc with your music. Instead, they are distributed among neighboring blocks of bytes — the bytes that makes up a single block are scattered about in a string of physical data blocks on the disk.

During playback, all of that information goes into a buffer and gets sorted out, reassembled.These metrics are regularly updated to reflect usage leading up to the last few days.

Fourier transformation can deconvolve superimposed signals created by the flow of multiple droplets into the message that a single droplet would transmit.

The constraints, advantages and unique error statistics of physical chemistry require us to rethink coding and decoding schemes for these systems. An analysis of our experiments with infofuses shows that the code presented is consistent with these schemes, and encouraging for the field of chemical communication and infochemistry given the vast permutations and combinations of allowable non-binary signals.

This paper investigates the out-of-sample predictability of international bond risk premia. We endogenously construct a global common Cochrane and Piazzesi (2005) factor. We find that the global factor strongly predicts international bond risk premia and delivers economically significant gains relative to the historical average. The forecasting power of the global factor is above and beyond the predictive power contained in country-specific factors. As predicted by economic theories, bond return forecasts appear countercyclical.

He has worked for a number of top bookmakers including Ladbrokes, William Hill and Coral. He's also written for a number of leading news outlets including the Guardian, i (newspaper) and Soccer Lens. More about him here. Matthew Finnegan joined IDG UK in January 2013, having spent two years writing for tech news titles including TechEye and ChannelBiz. Online gambling firm Bet365 has swapped Java for a lesser known programming language, Erlang, enabling it to reduce the complexity of software underpinning its core betting platforms and scale systems to handle a fourfold increase in the number of users on its network.

Created by developers at Ericsson two decades ago to run its telephone exchanges, Erlang is a relatively simple programming language designed for large, high-availability applications. It garnered little attention outside of the telecoms industry since the mid-nineties, but has grown in prominence in recent years, with WhatsApp using it to handle billions of messages sent across its network each day.

It meant that we could get our software out there faster, and we could test it quicker, and from that we could increase the productivity of our developers. The team's aim is to trial technologies that could give the company an advantage in the highly competitive online betting market.

The team began to look at how NoSQL and alternative programming languages can be used to solve the problem of growing complexity of its systems, which were unable to cope with growing customer demand and the need to develop software for modern servers which rely on multiple processor cores to improve performance. This meant that developers were forced to spend too much time maintaining existing systems to cope with bigger workloads, rather than focusing on creating new services.

Macklin says that the idea of using Erlang three years ago was unusual, but made sense for an application that required so much parallel processing - a similar issue to that of Ericsson's developers.

He adds that, to scale systems effectively in this manner, a simplified code base is required - and Erlang is tailored to this task. The firm can now manage sharp increases in demand during busy periods - such as major sporting events - without slowing service to customers.

We are an incredibly peaky business and we find that at the peak of trading we are able to provide our customer with a much more predictable quality product using Erlang," Macklin says.

This allows customers to close their position early and take a return before an event - such as a football match - has finished. Again it was about how we could leverage Erlang into that world. But once you get people through that initial pain barrier, the developers tend to really, really like it," Macklin insists. It is important to make it fun and intriguing, so developers can be passionate about it.

Around 10 percent of the 300 IT staff at the company are now proficient with the language, and Macklin expects it will be used more widely in applications in future. However, the firm will continue to rely on other languages, such as Java and.

NET, which are better suited to certain tasks. Macklin adds that, despite not having the same profile as Scala or other emerging languages, it is likely to continue to gain traction with other businesses. If you wanted a poster child for an organistion that has used Erlang and has been massively successful then they would be one.

But the effect that it has had on our business has been really good, and it has been very effective in the problems we have used it for.They will be once again without Matt Wilms in the middle. That will make the Miners defense much worse considering he's their enforcer type. Extra pressure now on Keith Frazier and Omega Harris.

UTEP has gone over in 14 of their last 21 games when the total is 140 to 149. This game features the 13-11 Sixers and the 18-8 Cavs. This game will be easy pickings as the Sixers will rest their star Joel Embid and this line just is too low.

Cavs lost outrite last night at the Pacers and will not be to happy going into this one. In the last nine years, this situation is sensational 23-3. The 7-5 Baltimore Ravens are in Pittsburgh to take on the 10-2 Steelers and for a number of different reasons, I think this on favors the visitors.

Baltimore has won three straight. Pittsburgh enters off a come-from-behind 23-20 win over Cincinnati on Monday night. Note that this is a revenge game for the Ravens after they fell 26-9 to the Steelers in the first meeting back on October 1st. Denver, which has lost eight in a row after a 3-1 start enters into this game in a shambles.

HC Vance Joseph's first year as head coach hasn't gone as planned, and the entire team looks to be on the verge of mutiny. Meanwhile, the Jets behind veteran quarterback Josh McCown are doing well in what was supposed to be a rebuilding season.

The experienced QB has 18 touchdown passes and only eight interceptions while playing every snap this season. Of the Jets' seven losses the jets have suffered during this campaign, only one has been by double digits, and they've had a fourth-quarter lead in three others and are a very under rated squad. I'm betting the NFL offensive player of the week (McCown) and a cohesive blue collar group will once again be the catalyst behind a Jets victory here today. DENVER is 0-8 ATS in all games where the total is between 35.

The Washington Redskins will visit the L. Chargers at StubHub Center Sunday afternoon, and I think we'll see a high-scoring affair. The Redskins took a 38-14 loss at Dallas last Thursday and need a win here to keep their almost non-existent playoff hopes alive. Over is 14-3 in Redskins last 17 games following a straight up loss and 6-1 in their last seven games in December.
