IPO spotlights Twitter co-founders
Investors, over the last 7 days, believe that there is more risk surrounding 1 mo Treasuries.

A treasury is an investment that you get when you lend the government money. They promise to pay you back with X% interest in a certain time period. In this case, we are talking about 1 month.

So, with the increase in interest rate from 0.10% to 0.27%, investors demand more return because they think it is now 170% more risky (Simply calculate the difference of 0.27 - 0.10), to lend the government money for a short-time period (1 mo), than it was just 7 days ago.

Yeah, 8 hours of essentially uninterrupted time is a lot to ask -- in fact it would basically be a deal-breaker for anyone with full-time commitments, or who otherwise values their time.

Also, (explicitly) timed coding tests imply that you don't really trust the candidate. Of course they could be lying when you casually ask how much time it took (or whether they got any help), but the few who go that route will probably quickly test out your other filters.

The trust signal, meanwhile, takes a lot of care and consideration to cultivate -- and shouldn't be discounted lightly.

I lived 1 block from this recycling center for 4 years. It attracts nefarious sort of homeless who among other pleasantries, defecate on sidewalks, break-in to parked cars, yell violently at each other and passerbys (probably due to mental illness of varying severity), and maintain packs of un-domesticated pit-bulls. I am pro-recycling but the patrons of this center are a danger to the community and that is why it is closing and should be closed. NIMBYism takes on a different meaning when your city allows violent, mentally-ill homeless to do as they wish on the streets w/o proper care. I think the recycling policy issue here is sort of tangential.

My point with the "sound collage" wasn't with the CONTENT, rather the MEDIUM. It makes more sense for me to ship a stereo recording across an established channel like a Compact Disc instead of coming up with my own proprietary medium. If I make an art form known as an "album" and I make it available on Compact Disc, I can plug in to an existing industrial infrastructure. Sound engineers, mixing engineers, networks of distribution, journalism, marketing... EVERYTHING has been built on top of the little plastic disc. If I forgo the little plastic disc, the album, well, I can't tap in to this industry. You literally can't get someone to review or promote your work as a musician unless you have a little plastic disc.

If you're interested in my "pet theory" of the medium being the message, I highly recommend you check out Understanding Media by Marshall McLuhan.

There's also what's called prepayment risk (or in this scenario I guess late-payment risk, but they're 2 sides of the same coin). For prepayment risk, essentially an investor thinks "OK, I put a lot of effort into this investment, but I don't have to worry about it for another x years". But the next month the investment returns at say a 15% yield, which would normally be great, but now you suddenly have to figure out what to do with that money and there may not be a similar quality investment around, at least one that's easy to find.

In this case, the bonds are such short term that the banks are probably using them basically as cash on hand to pay bills that are due at the end of the month or something while getting some return along the way. If the payment is delayed (or god forbid defaulted on entirely) suddenly they can't pay their bills. Then they have to either pull out of their other investments early (which will drop the prices of those investments), or turn to their own bond holders/power companies and say "it's not our fault we can't pay, it's the governments" which leads to a not-so-nice cascading effect. That's why Wall Street is so unsure what will happen, they aren't sure what they can do in the situation and how far their actions will cascade out.

Really?

The technical portion of the interview process described here is receiving a lot of well-deserved criticism, but I feel this is worth pointing out as well because it's another example of how out-of-touch this company seems to be.

Any experienced candidate knows The Rule (don't drink during the interview process, even at a social event), so an employer that intentionally puts a prospective employee in the position where he or she is effectively asked to do so is incredibly unthoughtful. And foolish to boot, as this could very well become a legal liability.

"If A then B." does not assume A.

We're not making that assumption.

We're talking about A because Israel extends certain privileges only to A-jews. Orthodox jews only accept A-jews.

If there's some explicit cutoff date (N generations back? 1900?) before which there's no brand attached to not having a jewish mother then I guess we should talk about A' instead.

I agree with you that text is too impersonal. The support page aims to address that somewhat by allowing video content: https://bitbucket.org/djarvis/world-politics/wiki/Supporting...

Corruption is only possible when you know who to bribe. By making the system completely anonymous, bribery becomes extraordinarily difficult, if not impossible.

Further, all ideas should receive equal consideration. Attaching names allows for group-think and bribery. (Imagine if Neil deGrasse Tyson posted a policy, or Neil Patrick Harris, or Neil Young.) Ideas must stand on their own merit, not on the reputation or wealth of the person who conceived the idea.
Sorry, that's not silly at all. You are taking the wrong context and you are fooling yourself thinking it is unimportant to question abililty.

Linked list is the simplest data structure one can pick it up in 5 minutes in using languages like Ruby and Python.

Do you honestly think any serious entrepreneurs would want a company growing hire someone who can't even tell you the basic of a linked list (can you imagine one cannot even tell you what a linked list is and the time complexity?)

You didn't even read my comment at all. A lot of things can be done by integrating with the ecosystem out there; but many of the libraries out there are horribly written and there are things you just can't build out of these libraries you find on PyPI.

People who build successful products cannot rely on an ecosystem forever. There are crucial components must be built by engineers using data structures and algorithms we know from textbook and then write custom algorithms that work for the use case.

Too bad. Some people just want to get away with ecosystem all the time; truth is you just cannot.

If a candidate never heard of linked list, wtf does that say about this candidate? Why would I want to hire him if he didn't even attempt to study a few one? I don't expect anyone to write a damn red-black tree algorithm; I can't and I doubt few people is capable of writing that algorithm from scratch (or even remember half of the properties).

I'm surprised this post received relatively few votes and discussion vs. the value I see in its message. Anecdotally, in addition to hiring and keeping top people this is the only other thing I've been able to identify that successful founders whom I know, do very well.

This has been my focus for the last two years, both personally and in business. It's paying dividends in both.

This, among others, gives me the impression that among VCs A16Z is the Founder's VC. The drive for profits and ruling by the numbers (favoured by accountants and investors) seems to be tempered by a very real grip and understanding of the reality a founder and their team faces.

Basically "the bar" stands more as an internal psychological mechanism than for any set of objective criteria. More about providing frustrated to feel good about themselves -- "we're soooo selective, that's why we can't find engineers that don't suck" -- rather than actually sit down and think about what what they might be doing wrong in their hiring process... or (probing further) why their company may not be doing anything all that interest in the first place.

As if, you know, the candidates don't also have a "bar" that companies have to muster up to. Yet if a candidate where to write a blog post musing that "only 1 in 100 qualified meet my bar", you probably wouldn't want to work with them.

do you want anybody who is interested to be able to dress up like a hobo and sift through your trash with impunity any time they feel like?

As far as I know, that is perfectly legal throughout the USA. Certainly there is no warrant required for the police to do exactly that.

I've actually got a big problem with the police doing that without any judicial supervision, but if it is OK for them to do it carte blanche, then in a just society it must be OK for anyone else to do it too.
What makes me incredibly sad in all this is the reaction of people. Specifically, Americans. I'm used to see this nation as the pinnacle of free spirit and liberty. Bold, fearless, freedom loving culture that will not tolerate any encroachment upon their rights and freedoms.

I can't see any of it. People are either indifferent or compliant. A few protests here and there that amount to nothing on the nation's scale. This is all despite the immense uproar in the press and media worldwide. What's worse, those few brave souls who dare to stand up against the injustice become social outcasts.

I guess these days people would have given up Robin Hood to the sheriff for a few gold coins and a promise of security. Or perhaps they already did.

I never said that. I said if people think the first bullet point is too much to handle, that's blatantly stupid. It isn't like the company is asking you to implement a red-black tree. I am not a fan of puzzle solver so I hate that kind of interview. But linked list? Come on.

it's like asking someone "Well, explain how list is implemented in Python" when you claim you have been programming with Python years. Well, if you can't even answer that question with a good estimate (it has a double space every time you create a list for example) then you probably shouldn't call yourself a Python guru.
It's pretty clear that a Clojure (or any other lisp) IDE would have to expand macros. This could potentially have side-effects, but there's really no (good) way around it. Besides, Clojure programmers are used to "passive" tools evaluating forms. Even documentation generators like marginalia and codox actually load a namespace rather than just examine the file, which could have side effects, too.
Here's a starting point to summarize thoughts on that question from some of the better known researchers involved in human studies.

http://impactaging.com/papers/v5/n7/full/100581.html

"Whether or not CR will extend lifespan in humans is not yet known, but accumulating data indicate that moderate CR with adequate nutrition has a powerful protective effect against obesity, type 2 diabetes, inflammation, hypertension, cardiovascular disease and reduces metabolic risk factors associated with cancer."

My summary of calorie restriction research is that it (a) produces similar-ish short term changes in metabolism and measures of health in mammals tried so far, and (b) is expected to have much smaller effects on life span in humans than in mice.

The present consensus is that 5 years in humans would be on the high end, as I recall.

The most interesting thing to resolve with certainty in this subfield is how the short-term measures can be so similar, how the expected reduction of age-related disease in humans can be so large, and yet the life expectancy outcome be so small. Should be interesting, in a post-facto sort of a way, as the time taken to figure that out will place us well into rejuvenation therapy territory, achieved through means that have nothing to do with CR or CR mimetics.

It feels like you're fishing to be told: quit, follow your dream, but here's some practical advice.

If you don't have a relevant degree, getting another job might take time. Unless you're not worried at all about your finances were you to not have work for around 12 months or so (to be safe), resigning now has some risk.

But there's no reason why you can't look for another job and/or apply to schools while employed at your current job. So why not dust off the resume, start looking for a new opportunity, and see what comes up?

Besides the absolute risks of default, an additional interpretation is that there is a risk that even if the shutdown/debt ceiling were worked out with no ultimate default - your principal and interest might end up tied up in some form of delayed hold on a one month scale, but that those issues are more likely to be resolved with no impact on a three month scale.
I hope everyone learned their lesson after all the panic over Italy/Greece/whoever defaulting and when senior MBS bonds took losses way back in 2009 and the code can handle defaults. I think the bigger risk would be from the portfolio rebalancing that would need to be done as what was assumed to be a 0 risk T-note is no longer 0 risk. That's of course ignoring the sudden "oh shit" heard all the way in southern Jersey when the notes don't actually pay out.

I'm not sure I understand your point about bribery. Are you talking about bribing groups of people to vote a particular way, or about bribing coercing powerful individuals not to express their opinions?

I disagree in practice that all ideas should have equal consideration. If an economist or other professional has a proposal, I think its practical to recognize that that person has extra credibility on a topic, and I don't see why we shouldn't let the public see that person's reputation. Professionals have an incentive not to state false claims--if the do so, especially in an internet forum board, they would be called out and their reputations would suffer.

On the other hand, there needs to be some anonymity to protect people from real life abuse. Do you see any problem with the option of anonymity?
