Why can't we expire two year old transactions?

1

Recycle lost/destroyed bitcoins by giving them back to miners

Miners will continue to get more transactions and thus more fees

If you already own bitcoin, this isn't a good thing as it increases the supply. That said, there is an altcoin called Freicoin that uses demurrage rather than an abrupt 2-year expiration that's got some of the property you're looking for.

Number of unspend transactions may become less speeding up verification

Size of blockchain to keep downloaded can be minimized

This may or may not be true as expiring coins gives people incentive to transfer them in order to not lose them. I would guess that given this fairly major economic incentive, the number of unspent transactions wouldn't actually go down that much.

Broken cryptographic hahes/signatures can be made obsolute

New features can be easily introduced

You seem to be of the opinion that what's keeping bitcoin from innovating is that there's all...

Some adjectives can only be used to modify nouns, for example the adjective indoor. We can talk about:

But we don't usually say:

*The pool was indoor (not good)

We call adjectives that appear before nouns attributive adjectives. The adjective indoor is called an attributive only adjective.

Other adjectives can't usually be used before a noun. We usually find these adjectives as the complements of verbs like BE, FEEL or BECOME. So we can say

She was afraid She felt afraid

But we cannot say:

*an afraid girl (not good)

Adjectives that we use like this are called predicative adjectives. The adjective afraid is a predicative only adjective.

We can use most adjectives as attributive adjective and predicative adjectives:

a huge elephant The elephant was huge.

Sometimes we have two adjectives that look similar and mean the same thing. One of them is attributive only, and the other predicative only. For example, the adjectives live and alive....

With national elections looming, many Americans are getting ready to show up at their polling place and mark paper ballots. Some have already cast their votes via absentee ballots, early voting, or vote-by-mail options.

But in this age of broadband Internet, smartphones, tablets, and near-ubiquitous connectivity, paper ballots – and all the problems they entail – seem tremendously backwards and counterproductive. After all, we trust billions of dollars in financial transactions to the Internet every day: Why can’t we use technology to do something simple like vote?

The reasons, of course, are complicated.

Advantages of online voting

Americans have been casting ballots at polling places for more than 200 years, but few would argue requiring citizens to show up in person at precincts, schools, churches, and other locations to cast votes is a perfect system. Simple access to polling places is a major issue for many voters, including the disabled...

The dr said it was just tantrums and he'd grow out of it....she was right. It took awhile, but he did eventually stop. He's my 2nd child, the 1st didn't do it this extensively. He still throws awful tantrums, but no longer bangs his head. he always had bruises along his whole forehead (all different shades of the rainbow) from all the banging. his speech caught up too, hes no longer in therapy. i never punished him for headbanging because he felt out of control as it is, so I didn't want to add to it by forcing him to be more angry. i let him work it out, have the tantrum, then cuddled him best i could after he was done to let him know i was here for him.

Definitely teach him the words to match what he is feeling. Hopefully he will eventually be able to communicate to you in that way instead of through head banging. How hard is he banging his head? Have you talked to the ped about this?

VIDEO: See Fred Hochberg defend the Ex-Im Bank in The Debrief, a new policy series.

The Export-Import Bank, the 80-year-old behind-the-scenes credit institution that suddenly became a juicy target for anti-government types last year, is on the chopping block. Tomorrow morning, its president and chairman, Fred Hochberg, will try to persuade congressional Republicans not to swing the axe.

The Ex-Im Bank's lending authority will expire June 30 if Congress doesn't agree to extend it, so there will be a lot at stake when Hochberg testifies before the House Financial Services Committee and its chairman, Rep. Jeb Hensarling of Texas, a leader of the effort to kill the bank. Hochberg then returns to the Hill on Thursday to face the Senate Banking Committee.

In the hearings he's sure to face some tough questions: Does the world's most powerful economy really need an export credit agency to help its companies do business abroad? How much of its work is essentially just...

Every bitcoin transaction that's sent flows into what's called the mempool (short for memory pool) before it can be confirmed by miners. When there's a dramatic spike in transaction activity, the mempool can become congested because so many transactions are waiting to be included in the next block.

Bitcoin users across the network may notice their transactions sit as unconfirmed or pending for a longer period of time, and we understand this can cause users to be concerned about the status of their funds.

In most cases, your transactions will eventually confirm. It may just take longer than usual to do so.

Note: The Blockchain Wallet has an Advanced Send option that allows users to specify a custom fee and this can come in handy to help ensure your transaction confirms quickly during periods of congestion. We recommend this option to experienced users with an understanding of transaction fees...

On June 24, 1980, Americans widely viewed a NBC documentary called “If Japan Can… Why Can’t We.” The program, part of NBC’s White Paper series, prominently featured Dr. W. Edwards Deming. Produced by Clare Crawford-Mason and narrated by Lloyd Dobyns, this documentary has been unavailable for public viewing for the past 35 years.

We are proud to announce that we have secured the perpetual rights for the program and are making it available here and on our website, free of charge.

This compelling documentary, about the ever-increasing industrial competition between the United States and Japan, introduced Dr. Deming to Americans. For the first time, they learned of the then 80-year old American who was widely credited with the Japanese industrial resurgence after WWII.

Viewers were astounded to learn that it was this American, Dr. Deming, who went to Japan in 1950 and began teaching his philosophy to their leadership. They listened and learned as he taught them...

Did you ever wonder why you have no memory of when you were a baby or very young child?

Researchers in the United States are investigating this question. The researchers work at Temple University in

Philadelphia, Pennsylvania.

The question of why adults do not remember how they learned to walk or talk has long been a mystery.

Nora Newcombe is a psychology professor at the university. She joined Zoe Ngo, a Temple graduate student, in the memory research project.

Newcombe says: "You know you learned how to walk and talk, but the funny thing is that you don't remember when and how you learned this."

The Temple University study involved computer-based tests. The tests were designed to work like games. They were given to 32 four-year-olds, 32 six-year-olds and 50 young adults.

The tests measured the memory process that helps people recognize differences between experiences. For example: A walk with your dog when...

We have lots of carseats in our household, the inevitable result of having three little kids who have overlapped carseat needs at different times. I look at the ones we don’t need any more, and they’re basically in perfect condition. A bit dirty, but structurally they’re perfect.
So why can’t we buy or sell them legally?
Maybe it’s just an oft-repeated myth that’s become accepted as law, but when we talk to local charities about donating car seats, we’re told that they can’t accept them because the carseats might be damaged or have structural flaws.
Huh?


Look at even the cheapest carseat on the market and you’ll instantly see that it’s basically one big piece of injection molded plastic with some buckles, clips, a seatbelt and a cloth cover. So what could go wrong?
That is, if there was something wrong with a carseat, wouldn’t it be immediately and overtly obvious? I mean, if you looked and there was a visible crack that let you prise the seat...

Bitcoin is the currency of the Internet: a distributed, worldwide, decentralized digital money. Unlike traditional currencies such as dollars, bitcoins are issued and managed without any central authority whatsoever: there is no government, company, or bank in charge of Bitcoin. As such, it is more resistant to wild inflation and corrupt banks. With Bitcoin, you can be your own bank.

The Internal Revenue Code does not make it easy to understand how Federal tax liens work. Hopefully, that is what I am here for.

The starting point to understanding your tax lien is to know that it lasts for the amount of time the IRS has to collect from you – 10 years. After the 10 year statute of limitations on collections expires, the IRS is required to release the lien. To accomplish this on a wide scale, the IRS inserts language into the lien that makes it “self-releasing.” That means it is automatically released when the 10 years is up.

This “self-releasing” aspect of a tax lien is right on the face of the lien. Here is what a Federal tax lien says:

“IMPORTANT RELEASE INFORMATION: For each assessment listed below, unless the lien is refiled by the date given in column(e), this notice shall, on the day following such date, operate as a certificate of release as defined in IRC 6325(a).”

Grab your tax lien (I know it may be painful to look at). The...

Reason #1: It can change the child/parent relationship.

LittleThings / Maya Borenstein

Between the ages of 0 and 2 years, an infant’s brain triples in size. A parent’s voice, touch, and eventually play can help build pathways in their brain that aid them in learning how to bond emotionally with other people.

But for children who spend too much time interacting with a screen, something different happens.

“Their neural pathways change and different ones are created,” says pediatric nurse Denise Daniels. “It affects concentration, self-esteem, in many cases they don’t have as deeply personal relationships.”

Reason #2: It becomes their first "addiction."

Why transactions are marked as pending:

If transactions have less than one confirmation from the Bitcoin network, they are marked as pending.

Why your transaction may have been pending for longer than expected:

Your transaction may take a long time to move from the pending state to the confirmed state for the following reasons: The wallet that the transaction originated from set a low fee on the transaction and has not been accepted by the Bitcoin network yet. The Bitcoin network could be under high contention due to high transaction volumes and so transactions can naturally take a long time to confirm. What can I do if my transaction has been pending for too long: If the transaction has been pending for longer than expected, check with the sender of the transaction to see if the fee set on the transaction was appropriate. If the fee seems appropriate try to request the "transaction ID" of the transaction and contact us at support@bitgo.com so that we can open a...

Many countries do have this mandatory military service policy, and it does have its benefits. For one, countries think more seriously about whether or not to go to war, as does the population since it is their kids going, possibly against their will.

As for arguments against it, a continual rotation of troops in and out of the military makes for a less efficient, well-trained military force. From a practical standpoint, there are more than 10 million Americans aged 18 - 20 (US Census estimates for 2009). We have no need for that many soldiers, nor do we have the facilities or funding to train and pay them. What's more, volunteer soldiers serve longer hitches, and are therefore better trained and experienced.

In the Vietnam War, we constantly cycled out new recruits every 15 months, just when they were learning how to do their jobs and fight a war, then we would bring in new soldiers to learn all over again. Compare that with the Iraq War, where professional soldiers...

Where do you go to find out how to make an app? Well, this is how I approached it, this is what I did. First of all, I've been programming in multiple other programming languages to get the basics down, such as Python, C, Java, etc. And then Apple released the iPhone, and with it, the iPhone software development kit, and the software development kit is a suite of tools for creating and programming an iPhone app. This opened up a whole new world of possibilities for me, and after playing with the software development kit a little bit, I made a couple of apps, I made some test apps. One of them happened to be "Earth Fortune," and I was ready to put "Earth Fortune" on the App Store, and so I persuaded my parents to pay the 99 dollar fee to be able to put my apps on the App Store. They agreed, and now I have apps on the App Store. I've gotten a lot of interest and encouragement ...

Happy May, money nerds—it’s time for our next challenge. This month, we’re bringing back a classic. We want you to flex your negotiation muscle and start haggling.

Negotiating doesn’t come easy for all of us. It can be intimidating, but half the battle is learning to speak up for yourself in the first place. Haggling is a great way to get used to asking for more money in a low-stakes environment. Even if you don’t feel comfortable haggling the cost of your car or your home, you can practice haggling on things like:

We’ve even written a guide on some surprising things you can negotiate (like rent). This is a challenge pretty much anyone can join, so who’s in? If you want to haggle together, let us know below, then tell us three things you plan to haggle this...

There is no excuse, at this point, for a professional technology writer to be confused by Snapchat. It has something like 200 million active users. It is, by some metrics, the fastest-growing social app in the world. It has been the subject of Wall Street Journal think pieces, Forbes profiles, and how-to guides for panicked parents. It’s 2015, for Zuck’s sake, and Snapchat’s basic functionality should be old news by now.

And yet, every time I try to use it, I feel like my father must have felt when I was 9 years old and challenged him to a game of Sonic the Hedgehog. I end up flustered and sweating, haplessly punching runic symbols in a doomed bid to accomplish the basic task of viewing my friends’ messages before they expire. Snapchat, in short, makes me feel old.

I recently discovered, to my great relief, that it isn’t just me. Snapchat makes almost everyone over the age of 25 feel old—even people who had never felt particularly old before. And that might be its...
