Your comparison to inject molding is correct. The press is used to hold the die mold halves together. I enjoyed this video that explained the process https://youtu.be/FUsicN-wKoY?t=234


I’m confused why the machine needs to apply a ‘pressing’ force to hold the dies together. Once the die is closed, can’t you just slide rigid clamps into place to hold it in position?


I don't think the metal is fully molten. That's why you need the huge pressures to bring it to shape


I don't understand this either.

The mould could have simple locking pins that lock it closed for the actual casting operation, and then unlock to remove the part.


People say this kind of thing a lot, but I’m pretty sure it’s simply not true. bash-completion handles pretty much everything I can imagine already, and can be extended to handle anything you can express programmatically.


We do the simplest thing we could imagine. Our sitemap of ~50,000,000 entries is written to static xml once a week as part of a batch job and pushed to S3. Is there any reason to believe it needs to be updated near real time? How often does Google read yours?


one thing is: freshness is a factor for google ranking. so if you could communicate a fresh page to google in exact the moment when new content arrives (+ there is a chance, that there is a "fresh" spike for search demand) then it's a factor.

but more important:

also with 50 000 000 URLs, as your site gets crawled with about 500 000 pages a day (which is average) or 1M pages a day (which is good) it takes already 50 to 100 days to index your whole site - so it makes sense to communicate only the changed sitemaps (at the exact time when they changed) to google, as the sitemaps get fetched quite fast you up your chances, that the new LP gets crawled/indexed faster. it depends on how fast your page turnaround is (new pages, updated pages, deleted pages) if it makes sense for you, or not.

(p.s.: in most cases for most business, a (near) real-time sitemap is overhead.)


By my math, Eduardo Saverin doesn’t avoid any tax at all by leaving the US, regardless of whether or not his stock goes up or down. If he leaves, the US takes 15% of his stock now. If he stays, the US takes 15% of his stock later. But either way, the US have taken away 15% of his ability to spend.

Let’s work through it with numbers, in case that isn’t clear. Say Saverin has $100 worth of Facebook stock. He renounces US citizenship. He sells enough stock to pay $15 to the government, leaving him with $85 in Facebook stock. Over the next year, Facebook doubles in value, leaving him with $170 in stock. He cashes out, and there’s no tax, so he ends up with $170 in cash.

Now imagine he stays in the US. He has $100 in Facebook stock, which he pays no tax on because there is no taxable event. Facebook doubles in value over the next year, so he ends up with $200 in stock. Then he cashes out, paying 15% in capital gains, leaving him with $170 cash.

Clearly he ends up with the same amount of cash either way. Perhaps Saverin is avoiding tax by leaving the US, but neither this article nor any other article I have read identifies how he is doing so.


See this comment below. Also you could make the case that you are locking in the 15% LT cap gains rate, which could and likely will increase at some unknown point in the future.

>> The numbers on and analysis of his tax liability in the article are demonstrably wrong - at a level of error unworthy of The Economist. His tax liability is calculated on the value of the stock as of the date he renounces citizenship, which was last September. Today, Facebook is worth maybe $100 billion. Early this year, a private equity offering put the value at $50 billion. Last fall, who knows, and it's all subject to negotiation with the IRS - my guess is no more than $25 billion. That means he evades 75 % of the tax bite by renouncing citizenship, and will be paying at most maybe $125 to $150 million of that $500 to $600 million tax liability he would owe if he sold all his stock next week.


If we assume that Saverin had to pay his taxes by selling shares at the same price at which the IRS assessed then, then my logic still holds. Saverin would have to sell 15% of his stock to pay the 15% tax.

If, as you suggest, he is able to sell his shares at a greater valuation than the IRS uses to calculate his exit tax, then you are correct. When you renounce your citizenship, I have no idea how long the IRS gives you to actually pony up the exit tax.


Here's how he's avoiding taxes:

He's making this move before Facebook is public.

Once Facebook is public, the value of his stake is much more transparent (and harder to fool around with). In your first example, the valuation of a privately-held company determines the exit tax. In your second example, Facebook is a public company and its valuation is determined by a public market. Singapore has no capital gains tax, so if he exits now with the lower private company valuation, he won't pay taxes on the difference.


To be clear, you are comparing a sharded Riak cluster against an unsharded MongoDB installation?



In 1729 Jonathan Swift anonymously published “A Modest Proposal for Preventing the Children of Poor People From Being a Burden on Their Parents or Country, and for Making Them Beneficial to the Publick” [1], which suggested that poverty and overpopulation in Ireland could be alleviated if the poor would either eat their children, or sell their children as food to the rich. In allusion to the original, the phrase “A Modest Proposal” is used to introduce suggestions that are satirical, hyperbolic, and sarcastic. Not knowing the origin of the phrase, some authors use it to introduce proposals that are genuinely modest, much to the disappointment of this reader.

While this proposal isn't quite as "modest" as Swift's, I would argue he's using the phrase correctly. You think he's actually suggesting making ratbots that survive off pizza crust and ferretbots to find them?

This sounds like a mockery of the pirate bay's proposal, just as Swift mocked how the people of his time thought about the poor.


To be clear, the title of the post, "Pirate LOSS? An alternative ...", makes no allusion to Swift.


While true, the submission title does, and the submitter is the author.


I find Sparrow for Mac much more pleasant than gmail or Mail.app. I’ve been on Sparrow’s beta build since the Sparrow beta started. I haven’t had any serious issues since version 1.0 was released, and I’ve received grateful replies to all of the minor issues I have emailed them about.

Sparrow for iOS is an insta-buy for me.


Did Kim Dotcom ever leave his house? Could it possibly have been cheaper, safer, and easier to, say, pull over his car and arrest him on the side of the road? Wouldn’t that also leave Dotcom less cause and opportunity to activate Megaupload’s alleged self-destruct mechanism?


They’re interesting problems, a good way to improve your coding skills, and an amazing way to train for interviews.
