Most problems can't be solved by a single map reduce. Map reduce tasks are normally written as a series of map reduce jobs; each map runs on the output of the previous reduce.

Since map reduce jobs write their output to disk at every step, it can be thought of as a form of check pointing. The difference between map reduce and mpi check pointing is that mpi needs to restart the whole job at the checkpoint, but map reduce frameworks can rerun just the work assigned to failed nodes. In the map reduce model, the checkpoint interval stays constant when adding additional nodes. With mpi, the checkpoint interval decreases as nodes are added because adding nodes increases the chance of at least one node failing in a given time interval and forcing the entire job to restart at the checkpoint.

Not all mpi jobs can easily be rewritten as map reduce jobs, but map reduce does address the problem discussed in the article.

Buying an iphone 4S would be a waste of money because the 5 will be usable for at least one year longer than the 4S. I am sure that any employees that want an iphone will be glad to wait a week to get the better phone.

The passage suggests that a seperation of church and state is permissible, but not required. Jesus said that paying taxes was required even if the government did not enforce religious law. If Jesus felt that Government was required to enforce religious law, he would have stated that ceaser's government was illegitimate and that paying taxes to him was forbidden.

I don't believe that there is any passage in the new testament that encourages theocratic government. Groups like the Westbroro Baptist church claim that god wants government to enforce old testament law even though the new testament focuses on spreading religion to people instead of using government to force people to follow divine law.

They don't appear to have banned all wine users. I run diablo 3 under wine and I just logged in and verified that i haven't been banned.

I believe that women don't form large numbers of businesses to bid for these contracts because of restrictions on subcontracting work on set aside contracts. I know that a small business that wins a small business contract must generally perform at least half of the labor on the contract. In particular, subcontracting the majority of the work on a small business to a large contractor is forbidden.

I assume that a woman owned small business would be forbidden to subcontract the majority of the labor on a contract to a male owned business and would need to somehow demonstrate that the owner of the company maintained control over the contract. Attempting to set up a male owned business with a female figurehead in order to win women owned small business contracts would be considered defrauding the government and would be prosecuted as a felony.

In addition, the government doesn't like to award contracts to one person companies on the promise that the company will be able to hire qualified candidates to perform the work after winning the contract. The government generally wants to see evidence that the contractor has successfully executed a similar contract in the past.

Unfortunately, the cheapest diesel you listed is only $300 less than a Prius and gets worse gas mileage. Unless the prices come down, I can't see myself buying a diesel.

The Mormons' rituals were already published at several other sites. The publication of the rituals has not had any impact on the Mormons' freedom of association. They don't like people publishing their rituals, but they still use them. They changed a few aspects of the rituals years ago when they were first published to get rid of elements that suggested Masonic influences, but this kind of revision has been done several times before.

I believe that people considering joining these kinds of organizations should have the ability to find out about the rituals and teachings of the organization before joining. The Mormon church delays participation in the temple rituals until after new members have formed strong social connections to the church. The availability of the Mormon rituals on the Internet allows prospective Mormons to make a more informed choice about joining the church. In contrast, I don't see any public benefit from the cultivation of confidential relations by organizations that aggressively recruit new members.

They do have a pretty good inventory system, but it isn't perfect. The inventory numbers can be off by a few items when product gets stolen, put in the stockroom without scanning the shelf to register the location, or accidentally destroyed or returned to the manufacturer without scanning the item out of inventory. When the store has plenty of stock, a discrepancy of one or two items isn't important. But when the store only shows 2 in stock, there is a significant chance that they don't actually have any. Especially for clearance items or items that have sold out at the warehouse, the last few items shown in inventory can linger for several week before someone clears them out of inventory.

Store employees can see the stock numbers, but directly displaying the numbers on the web site would result in angry customers who demand to know why the store can't find the last item in inventory. If you use the web site to check availability of an item in the store, it will show as in stock, out of stock, or limited stock. Limited stock basically means that the inventory system shows only a few of an item in stock, but the company doesn't want to promise that the number is accurate.

He doesn't need the cargo space of an SUV for the photography equipment, he needs the higher ground clearance to be able to drive on unmaintained backcountry roads. Forrest service roads are often covered with eight inch potholes and nearly impossible to drive in a normal car. I would like to have an SUV to trailheads in the wilderness, but I don't have one because I can't justify the cost of a second car.

If a bulb comes loose or gets twisted, that can still take out the whole strand. I bought a strand recently that wouldn't turn on. I had to pull out each bulb until I found the one with the bent leads. If the strand wasn't attached to a Christmas tree that I bought on clearance, I probably would have returned it to the store and it would have ended at the recycling plant in China.

I think google still made the right decision. Users expect the address bar to behave like a tab specific widget. It has different contents on each tab. If the user starts editing the address and then switches to another tab, they expect their changes to be restored when they switch back. Putting the address bar under the tabs clearly shows the relationship between the tabs and the address bar. For users that haven't used tabbed browsing before, the layout in chrome is more intuitive.

Chrome could include an option to change the location just because 50 people complained about the default on a bug, but that approach to design often leads to a crowded preferences dialog that is difficult to find anything in. Chrome often provides better default behavior that can't be reproduced by any combination of firefox settings. For example, Firefox has several different preferences that control tab behavior, but no combination of the preferences can produce chrome's behavior.

Chrome opens new windows as tabs in the foreground, but tabs explicitly opened by the user load in the background. I believe that I can use 'open in a new tab' to open a new web page in the background even if the page author requested it to load in a new window. Last time I used Firefox, using 'open in a new tab' on a link that the page author wanted to open in a new window didn't do anything at all. The behavior in Firefox doesn't make any sense to people who don't know the difference between a regular link, a link with a target attribute, and a link that uses javascript to open a window. I believe that the Firefox developers closed the bug about fixing 'open in a new tab'.

The Arab League may support the action, but that doesn't mean that the majority of the citizens in Arab League countries support it. A substantial number of those countries have large protest movements pressing for democracy. Some of them would rather shift the focus away from their own efforts to suppress dissent.

I don't think that the objective is clear either. We say that we are acting to prevent harm to civilians, but I don't think anyone really wants to indefinitely enforce a partition of Libya. If the rebels don't win in the next few years, the countries enforcing the no fly zone will probably expand their involvement just like the US did in Iraq.

Unfortunately, I don't think that will happen after the movie wrapped up the story line and killed off major characters.

It may not be part of the budget, but the treasury bonds held by the social security administration are definitely part of the national debt. The fraudulent accounting schemes used to hide the size of the national debt might prevent the government from making social security payments. When the baby boomers start retiring in large numbers, the government will have to issue bonds to the public in order to redeem the bonds held by social security. Unless we get the budget balanced soon, we won't be able to afford to redeem the social security bonds.

The lottery system probably logs ticket sales and ticket checks to a central server. Attempting to check tickets before buying them would probably raise a red flag.
