Why are there so many confirmations?


new programming languages are built for many different reasons, mostly because there are new programming paradigm, or because of advances in hardware people create new language to take advantage of the new hardware features like multitasking, etc.

in my case, I usually build small compilers( with a new programming language), for specialty reason. if I make allot of games, and I believe that a programming language specifically made for game development will result in smaller faster code and faster development turn around, then I build it. and at then end it turns out that it can also be used for other general purpose programming.

I think most people who create programming languages have a specific purpose in mind, there are those who create them for general purpose from the beginning. but most are not.

By the way, I do think there are way too many programming languages, but hundred of new ones will always come out. some out of fun, some out of a niche purpose,...

Today’s Wonder of the Day was inspired by Irene from , . Irene Wonders, “I wonder how language started.” Thanks for WONDERing with us, Irene!

How many languages do you speak? If you're a student in the United States, the answer might be just one: English. Of course, many U.S. students speak two languages, such as English and Spanish, while other students may speak a few different languages.

You're probably familiar with the foreign languages spoken in many countries. For example, if you lived in France, you would speak what? French, of course! What about Germany? German, naturally! But what about the many other nations around the world? Just how many languages are there, and why are there so many?

Linguists, experts who study language, don't have all the answers. Human beings have been communicating with spoken languages since their earliest days on Earth. Some people theorize that everyone once spoke a common language. Whether that's true or not can't be...

The first version of Google Translate (the Rosetta Stone).

Why would the world ever need 1000s of languages? If you believe we all evolved together as a species, why did we start speaking so many strange tongues? I mean, it’s certainly easier for us to just all speak one language, so why did things evolve differently than they did?

Especially since there is no shortage of variety when it comes to languages. From languages that don’ have words for right and left (they use north, south, east and west instead) to the 800 or so languages spoken in Papua New Guinea. There are relatively simple languages like Indonesian and overly complex languages like Japanese and Arabic.

Even experts can’t really answer this question quite clearly. Noam Chomsky, famous linguist/activist, doesn’t really give us a clear answer. Mostly because we don’t really have any good evidence. The only language fossils we can study are written works, and not many of those have survived from...

Different operating systems support different file systems. Your removable drive should use FAT32 for best compatibility, unless it’s bigger and needs NTFS. Mac-formatted drives use HFS+ and don’t work with Windows. And Linux has its own file systems, too.

Unfortunately, even typical computer users need to think about the different file systems and what they’re compatible with. Here’s what you need to know about file systems — and why there are so many different ones.

File Systems 101

Different file systems are simply different ways of organizing and storing files on a hard drive, flash drive, or any other storage device. Each storage device has one or more partitions, and each partition is “formatted” with a file system. The formatting process simply creates an empty file system of that type on the device.

A file system provides a way of separating the data on the drive into individual pieces, which are the files. It also provides a way to...

If you have sent a bitcoin payment in the last couple of weeks, you may have noticed that your transactions are taking much longer than expected to confirm.

We have received your emails.

Since, like the Bitcoin network, we are currently working through a backlog, we want to thank you for your patience. With the high volume of questions we're getting about delayed payments, we decided it would be best to write a short explanation about what's happening with many bitcoin transactions right now.

Transactions on the Bitcoin network itself aren't controlled or confirmed by BitPay, but by the bitcoin miners which group transactions into "blocks" and add those blocks to the Bitcoin "blockchain" – the shared historical record of all transactions. When a transaction has been added to a block six blocks ago, it's considered a done deal.

Currently, bitcoin network traffic is unusually high due to increasing demand for transactions per block. Block sizes are...

WASHINGTON, D.C.—At his confirmation hearing on Tuesday, Sen. Jeff Sessions did a commendable job keeping up a steady and smooth defense of his nomination to be President elect Donald Trump’s attorney general. Sessions disavowed the most egregious elements of Trump’s attacks on the Constitution, including rejecting the idea of a Muslim registry or surveillance of mosques. He also affirmed that Roe v. Wade is established—although “colossally erroneous”—law, and he offered that he would recuse himself from any investigation involving Hillary Clinton, based on comments he made during the campaign. That promised investigation, Trump has already said, will not happen.

For hours on end, Sessions rebuffed, usually extremely deftly, forceful questioning from Senate Democrats about controversial statements he has made about the Voting Rights Act, his history with civil rights litigation, and his refusal to support legislation punishing violence against women. He confirmed that...

Here's a paradox you don't hear much about: despite a century of creating machines to do our work for us, the proportion of adults in the US with a job has consistently gone up for the past 125 years. Why hasn't human labor become redundant and our skills obsolete? In this talk about the future of work, economist David Autor addresses the question of why there are still so many jobs and comes up with a surprising, hopeful answer.

Question: "Why are there so many atheists?"


Before we can discuss atheism, we need to define it. According to an official atheism website, atheists define themselves this way: “Atheism is not a disbelief in gods or a denial of gods; it is a lack of belief in gods.” Those who identify as atheists prefer to emphasize their lack of belief rather than the refusal to believe. They consider atheism to be intellectually superior to faith in God. However, this definition clashes with the biblical worldview, which states, “The fool says in his heart, ‘There is no God’” (Psalm 14:1; 53:1). Since atheists can agree with people of faith that every human being has the freedom to choose what he or she thinks or believes, we will define atheism here as the choice to disbelieve in any kind of Supreme Being to which mankind is accountable.

Statistics show that atheism is on the rise in countries that have historically had a strong Christian influence. These statistics include those...

Here’s an article that was in the works from July of 2009 that never saw publication.

While people are no longer building ad networks (that game died 5 years ago), understanding how networks behave is critical if you want to make money via optimization (arbitrage between the supply and demand– the publisher and the advertiser).

Tactics like scrubbing don’t work anymore– but the basic principles never change, which is our reason for reviving this article. The game never changes- SEO Consultants become Social Media Gurus who become Content marketing wizards, and so on- like wolves who discard their worn out old sheep skin only to don another.

Why are there SO MANY ad networks? How to start YOURS!

Every day, another ad network launches. What’s the deal? Google “ad network” and you’ll see 137 million results and see thousands of companies. AdKnowledge, AdBrite, Adfish, Adsdaq, GetAds, E-ads. This evening I was driving down the road and saw a sign for “Be...

Why are there so many denominations in the world when Jesus said that He would build His church? Why are there so many churches with so many different doctrines? Didn’t Jesus say that He would build His one true church? Is there such a thing as the universal church?

Why Are There So Many Churches?

There are an estimated 37 million churches in the world with 50,000 new ones added every year and no two are the same. There are so many churches because there are so many Christians in the world. In fact, 1/3rd of the world’s population are Christ followers and it is growing exponentially too. These figures do not count the millions of underground and house churches where it is dangerous to profess your faith publicly. One lady in a Muslim country was thrashed and beaten for simply wearing a cross to school and the local police failed to file any charges against the school and in fact, threatened the lady herself that they could not possibly protect her if she ever wore a...

Have you ever wondered why there are so many different Christian churches and denominations? Until the Protestant Reformation, the Christian Church was largely composed of only two groups or "denominations": the Roman Catholic Church in the west and the Greek Orthodox Church in the east. With the Reformation, however, as neglected Bible truths began to be restored and emphasized, different denominations arose holding different doctrinal positions on a number of issues. Sometimes these differences were rather minor; in other cases, they were quite significant. Other Christian denominations grew up around a gifted spiritual leader, such as Martin Luther (Lutherans), John Calvin (Calvinists), John Wesley (Methodists), or in more modern times Joseph Smith (Mormonism) and Mary Baker Eddy (Christian Science).

Unity Among Christian Denominations?

Jesus prayed that His followers would be one (see John 17:20-23). Unity is an...

I was asked this question twice in the past week, by colleagues who work with our clients. It sounds like a dumb question, but it’s not.

The short answer is that we don’t need so many languages, but we want them. Let’s explore this further.

Aren’t they all the same?

In a sense, yes. You can create a web site using Ruby, Java, Python, C#, Go or JavaScript. You can use C or C++ or Haskell or Rust. Or COBOL or Pascal or Perl.

Underlying this fact is that all of these languages serve the same purpose: to turn human thoughts into the 1’s and 0’s that the computer understands. In highfalutin computer terms, they are all “Turing complete”.

At their most foundational level, these languages are all the same. But on the surface – where humans interact with them – they vary a lot. This is where other concerns come into play.

Programming languages are tools, and we choose different tools for different jobs. A...

It is known by many as the document that ultimately resulted in modern democracy. So why are there so many versions around of Magna Carta?

Magna Carta is one of the most important, well-known documents in history and next year marks its 800th anniversary.

To celebrate this, London Metropolitan Archives is putting on display its version in a new heritage gallery.

"People imagine that it's going to be really pretty, and that it's going to be an illuminated manuscript, and it's not, but that's really interesting because it's a working document," said Geoff Pick, director.

"It was a negotiated peace treaty between warring sides."

It is not the only one that is on display of course - there are in fact 17 copies of the Magna Carta which are known to have survived over the years.

But why are there so many?

The document was a peace treaty first agreed by King John in 1215 to appease rebel barons in the heart of battle.

Once the treaty...

I host several Rails applications on a VPS using Ubuntu 8.04, Nginx, Passenger, Mysql, RVM, so all the usual suspects.

In the last days it was the first time I really had to debug a problem and look at which processes are running. I could fix the problem using passenger-status and passenger-memory-stats, but I am quite confused by the number of processes running and can't quite figure it out.

Take a look at this screenshot for example: http://screencast.com/t/wUMrmy5iQPQi (taken from htop)

It shows lots of Hudson processes (Hudson is the CI server I am running on that machine).

My questions are:

Why are there 34 of them? Are they all separate processes? Are there supposed to be 34 of them or are some of them stale, orphaned processes that didn't shutdown properly on a restart and which I should...

A confirmation is when a transaction makes its way from the transaction pool in to the blockchain.

Or in other words, it's when a bitcoin transaction becomes irreversable.


How does it work?


When you make a bitcoin transaction, you're basically inserting a line of data in to the bitcoin network.

This transaction data then gets relayed from node to node, until everyone on the network holds a copy of your transaction.

But initially, new bitcoin transactions are held the "memory pools" of each node. This is like temporary memory on the bitcoin network.

Transactions in these memory pools are all valid, but they're not permanently stored on the network (yet). For that to happen, they need to be written to a file called the blockchain.

Once a transaction gets written to the blockchain, it's pretty much in there forever.

So until a transaction is "confirmed" and gets written in to the blockchain, it...

Recent years have seen a proliferation of right-wing activist meetings unmatched on the left. The result: a fired-up base for the GOP.


Last Friday morning, the conservative author and commentator Jonah Goldberg began his day with a speech to the Faith and Freedom Coalition's annual conference, a gathering of more than 1,000 social-conservative activists in Washington, D.C. After delivering his fiery address on the evils of liberalism to a packed and attentive hotel ballroom, he headed for the airport -- bound for Las Vegas to address another conservative confab, the RightOnline convention of conservative bloggers.

"It does seem like these things are proliferating," Goldberg, whose willingness to travel is enhanced by the fact that he has a new book to promote, mused in an interview upon his return to D.C. on an unpleasant red-eye flight. Even with the book-tour imperative as motivation, the ceaseless circuit of sometimes overlapping gatherings can get...

By forbidding "interesting" question about practical problems as "too broad", we have drove ourselves into a dead end of "fix my codez for me" one-off issues, and the resulting lack of interesting questions and/or hardness to find them is already making experts drift off the site.

Let's test that theory. If you're right, then we should be able to find some "interesting" questions that have been closed as "too broad", right? I looked through the last 100 questions to be asked on the opengl tag. Here are those that were closed as "Too Broad":

How to draw objects in OpenCV Python and opengl Draw in OpenGL Text by pixels How to put a PNG texture on quad, with gl.h library only?

I see nothing in that list that is the slightest bit interesting. They're all basically "write me a tutorial" questions. They're smaller in scope than "how do I build a website," yes. But they're still asking for large-scale stuff. They're also all "how do I get started" kinds of questions, which...

Why do we still need Black History Month? On its first day alone, this February provided two good answers. One is that we need it because our president and his spokesman seem to have no idea who Frederick Douglass was or even that he is not currently alive. But a second is that, mysteriously, it seems a large number of Americans believe that the inventor of the cotton gin, Eli Whitney, was black.

This became a topic of chatter online on Wednesday when Rembert Browne, a writer-at-large for New York magazine, tweeted about it:

yearly reminder that half the country was incorrectly taught that eli whitney was black

— Rembert Browne (@rembert) February 1, 2017

He was quickly deluged with confirmations that this is indeed a thing:

What’s going on? First things first: Whitney was white. He is not a mysterious figure. He was born in 1765 in Massachusetts to a wealthy farming family, he went to Yale, he married Jonathan Edwards’ granddaughter, and he...

Why do so many religious believers want atheists to lie about our atheism?

It seems backward. Believers are always telling atheists that we need religion for morality; that we have to believe because without religion, people would have no reason not to murder and steal and lie. And yet, all too often, they ask us to lie. When atheists come out of the closet and tell the people in our lives that we don’t believe in God, all too often the reaction is to try to shove us back in.

In some cases, they simply want us to keep our mouths shut: when the topic of religion comes up, they want us to tell the lie of omission. But much of the time, they actually ask us to lie outright. They ask us to lie to other family members. They ask us to attend church or other religious services. They sometimes even ask us to perform important religious rituals, like funerals or confirmations, where we’re not just lying to the people...

Trump claimed that the co-hosts of MSNBC's "Morning Joe," Joe Scarborough and Mika Brzezinski, "insisted" on joining him in Mar-a-Lago earlier in the year, and said Brzezinski was "bleeding from a face-lift" in a tweet sent on June 29, 2017,

"I heard poorly rated @Morning_Joe speaks badly of me (don't watch anymore). Then how come low I.Q. Crazy Mika, along with Psycho Joe, came to Mar-a-Lago 3 nights in a row around New Year's Eve, and insisted on joining me. She was bleeding badly from a face-lift. I said no!" he wrote.

According to reports, Trump actually agreed to speak with Scarborough and Brzezinski when they were in Mar-a-Lago, and there's no evidence that Brzezinski's face was bleeding.

The MSNBC host appeared to respond to Trump's tweet with a photo of a Cheerios box that reads, "Made For Little Hands," likely referring to claims that the president has small hands.

Sen. Lindsey Graham also responded to Trump's tweet, writing, "Mr. President,...

The following cultural patterns may represent many African Americans, but do not represent all people in a community. Each person is an individual, as well as a community member. The term African American generally refers to people descended from Africans who did not come to the US voluntarily—descendants of the four million slaves brought to the US between 1600 and 1800.

Social structure

According to the University of California School of Nursing, in Culture and Clinical Care, many aspects of African American culture today reflect the culture of the general US population. The structure in African American families is often nuclear and extended with non-related “family” members. The family may be matriarchal, although father or mother may take on the decision-making role. For African Americans, women more than men tend to remain unmarried, and more women have been educated at the college level.

In general, the older generation is more conservative, may...

Walmart, Target, and Costco Among Major Retailers Affected

Shoppers’ email inboxes have just started being flooded with a timely and potentially dangerous scam. Cybercrooks are sending out authentic-looking order confirmation emails that appear to be from Walmart, Target, and Costco, among others, to lure unsuspecting shoppers to their fake websites, according to ConsumerWorld.org.

Upon clicking the link for more information about their supposed order, consumers are taken to a foreign website where a malware-infested .zip file is automatically downloaded to their computer.

“This is the perfect crime at the perfect time,” commented Consumer World founder Edgar Dworsky. “Shoppers are busy placing orders between Black Friday and Cyber Monday, so they would naturally expect to find these confirmations in their inbox. And even if they didn’t place an order with the particular retailer, they may believe that a mistake may have taken place and want to see the...

The Supreme Court confirmation process is broken. Republicans say Democrats started it with their ruthless take down of Robert Bork three decades ago. Democrats say Republicans crossed a line when they covered their ears and pretended President Obama had not nominated Merrick Garland to fill the seat left vacant by Justice Antonin Scalia’s death.

It is high time to say to the Senate what a parent says to bickering toddlers: I don’t care who started it, I care who ends it.

In that spirit, I propose a truce on the following terms. First, Republicans must agree not to eliminate the filibuster for the current vacancy. In exchange, Republicans and Democrats make a bipartisan commitment not to invoke the filibuster for the next vacancy. After that, both sides agree to return to the status quo before Scalia’s death, where the filibuster was available but almost never used.

Let’s unpack what this would mean in practical terms. If the Senate retains the filibuster for...
