1. it does have the benefit that it's cross-cultural, you can actually talk to people outside your cultural bubble

2. it's got the advantage that you're using the same measurements as all your trade partners so people don't need two production lines anymore

3. it's got the advantage that people going into science and engineering don't need to build a whole new set of unit references because they've got the one which already works

4. the "huge expense" is pretty much made out of whole cloth for the purpose of saying you can't switch, the UK's metrication cost basically nothing except for road sign replacements which is why those are still imperial

Earthquake resistance isn't an immediate win for low-density housing.
Tall buildings can be safer in an earthquake than single-family homes and low-rise townhouses, both due to a lower structural resonance frequency and the ability to spread the cost of advanced safety features (like mass dampers) across more tenants.
I don't believe that it does cap the range. I see it as:
At least x (where x = 10-20). X is the minimum, and you can always exceed it, whether it is a single value or a range.

If you bake 100 brownies, you satisfy the requirement of baking at least 10 brownies, as well as the requirement of baking at least 10 to 20 brownies.
This is an often repeated claim, but things do not become true by repetition.

First of all, HFTs have certainly taken over market making functions in today's markets, almost entirely in equities, to a lesser extent in some other asset classes.

Yes, it is true that some HFTs will stop trading during extreme volatility events (but they are not consuming volatility either, merely not providing it any more). But the same was true of human market makers of the past (there is a famous story of NASDAQ brokers simply stopping to answer their phones during crashes in the '80s, even though they were required to always make markets by regulation) - so who are you comparing them too?

The flip side is that HFTs (as any market maker) make more money when the volatility is high, so they have strong incentives to get back in there providing liquidity.

Well, it's the same thing, but without the atmoics. Rc and Arc only differ in the instructions used to update the count, Rc uses regular increment, Arc uses atomic increment. The code is otherwise the same.
You should look at crash tests results of your 2000 Subaru and a car more modern than 2013 and decide which you'd rather be in in the result of a crash. I'm less scared of a potential hacker cutting power to my car than I am of the millions of poor drivers cutting lanes and changing lanes without signals (or even looking) resulting in an auto accident.

Things started improving in the 90's (falling from 143m to 115m). In 2000 it was at 112m. 2008 saw the sharpest decline - down to 78m. In 2012 it was 65m.

The difference between 112m and 65m is staggering - and is largely due to newer, safer cars being on the road.

All figures above are driver deaths per million for registered vehicles taken from: http://www.iihs.org/iihs/sr/statusreport/article/50/1/1

E:

Although Subaru has a good track record of safety. I just think the fear is misplaced. For most people driving older cars, I'd be far more scared about my safety during a crash than my safety from a potential hacker.

Both are of concern, of course.
Java (the most popular programming language in the world by many metrics, if you didn't know) works exactly like this.

I understand that C and Java have (sometimes) different use cases, still I feel reasonably confident that 32-bit arithmetic is going to be efficient enough on most platforms of interest (some embedded platforms might be a problem).

It's true that something like the Posix int_fast_16_t (etc) types might be useful though.

Runit is great for wrapping software that runs well in the foreground, but maybe doesn't handle being a daemon very well. This often goes for software written at / by a particular company, and software not written with large-scale use in mind. For system-level services, I usually stick with whatever the system I'm on does.

If you changed the sizes of lumber, I'm pretty sure that someone would come out with "new inch" tapes that were labeled with inches and feet but accounted for the change in size (spreading the extra millimeters out across the distance).

The dimensions in use are something that people are very used to working with and they know how to do the necessary mental arithmetic to work with them.
> costs are lot lower than ever.

Depends on your time frame. Back in 2005 or so (until NASDAQ bought INET), you could get everything INET for ~$1000/month, and be on par with the big guys (as far as INET was concerned). And practically overnight after NASDAQ bought them, the price went up to ~$6000 (for exactly the same service).

And HFTs are (at least partially) to blame - they all used INET, raising the volume there significantly, which got NASDAQ scared, rushed to buy INET, and jack up the price to pay for it (and because now, monopolizing the nasdaq trades again, they could).

Also back in 2005, Eurex did NOT have a fast feed, only a slow one (updating twice a second, if memory serves me right, and fitting on a 512Kb line). And it cost just a couple of hundred dollars to get above infrastructure costs (dedicated line, data providers, trading systems, etc). Then the fast feed came, and it costs thousands of dollars per month (in addition to infrastructure). And it came because of the HFTs.

Costs are lower than ever in the sense that slow data is cheaper than it was, and fast data is cheaper than it was. However, costs are not at all lower than ever in the sense that in 2000 to ~2006, you could be on par with the most sophisticated players for much cheaper than you can today.

> You had to have guys on the floor of the exchange. If you think paying them was cheaper than a direct feed, then you are wrong.

Although the floors still dominated in the early 2000s, you only needed to trade them if you traded huge blocks. Smaller blocks worked perfectly well (and more efficiently, and with much better price discovery) on the electronic exchanges. How far back are you thinking of?

> Direct feeds cost money because....everything costs money. Exchanges are businesses, why should they give away their data for free ?

They shouldn't. Some people (me not among them) think it's unfair that to get that data completely and timely is so expensive.

Personally, I think the unfairness runs so much deeper that it makes no difference. And I also think that expectations of fairness are also misguided. As you mentioned, the exchanges are businesses - they are in business of making money, not of being fair. Unfortunately, most people are blind to that.

While that may be true, as the article points out, all it takes is for someone, anywhere, to slip up once, and then you possibly have a serious security violation. Having the compiler double-check your work is nice.

Any manufacturing component which cannot easily be adjusted to a slightly different measurement is poorly designed, in my opinion. I would expect that much of these tools could be tweaked to produce things in metric measurements. If not, the dimensions can simply be converted and re-labeled. If something manufactures a square piece of metal that is 3" by 3", is it a huge deal to just document it as being 76.2mm by 76.2mm?
> Apart from some things like miles and gallons which would require a massive synchronised change that is.

It's less the synchronisation and more the expense of replacing all road signs throughout the kingdom, making it a political non-priority.
This is a way that fixing income inequality would help certain entrepreneurs. If more money can come from customers (poor/middle class/small business) rather than investors, then early revenue will be more attainable than early fundraising.

Decentralizing economic power would shift our economy away from capital-intensive moonshots and toward consumer products though.
Seems like a different issue. Nothing about the start time says anything about how much sleep you get.

On the other hand people sleep better in the dark so if your start time implies you're going to bed when it's light out it could cause problems. Unless you use a prosthetic night (curtains).

Why should he be the one to decide if the leaking of over a million highly classified documents is a "risk worth taking" to inform Americans of the phone metadata program? Doesn't that seem just odd to you? If I wanted to blow the whistle on a program I thought was illegal, I'd gather supporting documents and evidence of that one program (to include supposed emails I had sent in an attempt to follow the proper "channels" for reporting illegal activity - which in Snowden's case are conspicuously absent from the data he stole) so as to not discredit my work/sacrifice by leaking magnitudes more than I needed to.

Why not just leak documents related to that one issue? If he had, I would not hesitate in the least to call him a whistle blower, and in fact I think he'd be living as a free man right now if that were the case.
A lot of people further neglect all the prior art in init replacements before those. The simpleinit dependency mechanism, depinit, initng, minit, daemond, Seth Nickell's GNOME experiments, eINIT, cinit and so forth.

Instead, the way it was presented in public is that the Linux distros had been battling with brittle sysvinit scripts (true, but also largely self-inflicted) for so long until systemd came in to heroically save the day.

It was pretty shocking to watch how the scene evolved from apathy to having an urgent problem that must be solved now.
On the spam thing, I believe what they're saying is that companies set up a service, then they disappear, the phone number they used gets reassigned to some Joe Random, and then poor hapless Joe gets spammed by all the company's former customers who think the number is still hooked up.

> More like a whole new ballpark in the devastation of human rights.

Depends, if the technique is easy enough for individuals to accomplish, it becomes a health issue rather than a crime one, because nobody will need suppliers/dealers/smugglers.

The real problem is the middle-ground, where it's an easy production mechanism that criminal syndicates can control, but not so easy that individuals can do it without making payments. For example, perhaps the cultivation/extraction/concentration process is too difficult, or the strain is engineered to require a proprietary chemical to live--a reasonable safety precaution in any event--or the "root species" is kept secret while strains that self-destruct after a certain number of generations are used for production at scale or resale.
Modafinil also, in my experience, does not make you likely to sleep less over time. What it does let you, similar to caffeine - but totally different feeling - let you portion out your sleep differently. Whether I delay sleeping with caffeine or modafinil, I end up wearing down until I catch up.

In my opinion, efficiently using our current methods for deferring sleep boils down to understanding that you're merely deferring it, and using it to "schedule" your most awake/concentrated periods when you need it most, rather than try to force yourself to work well all the time.

Maybe one day we have something that can let us cut sleep entirely, but we're still far away from that.

EDIT: As I've clarified in another comment below, my sleep amounts without anything are already fairly low, and that may certainly affect my ability to push it further down with modafinil over the long term.
It isn't just taking on risk by trying something new. Even a known better solution can result in assuming risk.

Take a long existing systematic problem which produces 100 bad effects a day (people getting double billed, database errors, what have you). Someone thinks of an improvement to reduce this to 10 bad effects a day instead. A major improvement. But they don't do it.

Why? Because anyone who approves of the new system is now the person responsible for the 10 errors a day. It goes from 100 errors per day because that is just how the system works to 10 errors a day because of Bob two cubes over. Bob ends up being blamed for the 10 errors far more than being congratulated for the 90 that no longer occur.

It seems more that Curcumin that isn't passed into the kidneys can pass the blood-brain barrier[0], and you can help prevent that by taking it with piperine; most formulations, at least on Amazon, have piperine in it, if it doesn't take it with some black peppercorns. It appears the only difference between most formulations and Longvida is that they pair it with coconut oil? That's what I could gather from their formulation, they don't even list piperine.

I'm skeptical of the brand in particular, not in the sense that it's bio-available, but their claim that only their brand crosses the blood-brain barrier[1][2].

[0] a lot of sites mention this in passing, but here's a study that shows 7 days of supplementation crosses the blood-brain barrier, at least in mice: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2781139/

Even if you want to build a scalable/fundable startup, stop looking for a cofounder. It's needy and the wrong motivation. Start working on the project get help from the smartest people you know / can find. Get their help in any capacity you can. You're more likely to find a cofounder indirectly through on this path than in an overt "cofounder search". Plus you'll actually be making progress.

The fact that sleep still exists seems to suggest that this is hard and involves some nasty tradeoffs between the "dishwasher mode" and more operational neurological states. It's also likely that more than just this occurs, and that sleep is used to take care of a whole laundry list of housekeeping operations.

We have "pausing GC"... heh.
"Is designed for" implies a lot more than what it means here. If I remember correctly, the mechanism behind Modafinil is unclear. The usage is approved for narcoleptics, but also for people who want to shift their circadian rhythm (because it [allegedly] doesn't carry the sleep debt that other stimulants do).

Is there any information (affirmative or negative) about Modafinil's effects on this plaque? Considering how recent this whole discovery seems to be, I doubt there's much conclusive info on this specific interaction.

I am going to venture a guess here that the type (and volume) of music you listen to vastly affects your output productivity. I know people that write code to loud death metal. You see them hammering their fingers on the keyboard obviously in sync to the music, their feet making beats on the floor. Other people listen to altrock or whatever the kids listen to these days; I'm such an awful hipster. I feel like I can guarantee these people aren't making breakthroughs.

I cannot listen to any kind of music while programming except ambient/chillout electronic (Solar Fields, Carbon-Based Lifeforms, Sync24, Aes Dana, Asura, etc). This music has no lyrics, and most importantly gets me into flow extremely quickly and keeps me there longer than if I didn't listen to music. When I am in flow, I have personal "genius breakthroughs", full stop. If there is a benefit to working in a quiet room, I have never noticed it over the twenty years I've been programming.
I'm not saying these people deserve anything here. That's a complex question whose answer I don't know and which I haven't given nearly enough thought to.

I'm merely saying, if you evict these people (which may be an entirely reasonable and justified action) then $20,000 isn't necessarily going to go very far in making it up to them.

As to whether they deserve more, or less, or anything, I don't know. You'll probably want to take that up with the parent comment.
You're confusing vanilla DNSSEC with its proposed uses/abuses. DNSSEC just enforces the trust model that was already in place (the hierarchical nature of DNS) to ensure the authority and integrity of DNS responses. It doesn't provide confidentiality because that simply doesn't work in the shared DNS forwarder+cache model we all currently depend upon, much like HTTPS renders shared HTTP caches useless (which has implications for CDNs for example).

Proposals like DANE, using TLSA records, or deploying SSHFP records on DNSSEC enabled domains, are a different kettle of fish.

Whether or not you believe in DANE really depends on whether you're willing to accept that the DNS infrastructure is already security critical. Truth be told, if I can hijack your DNS, I can get a certificate for your domain using simple domain validation... but that's true of your web server as well. There's no easy answer here.
I think SF is building the Central Subway pretty quickly. It looks like the subway will be completed in a few years. It seems like a success in terms of putting new infrastructure in a crowded city.

The BART SFO extension took about 30 years to complete. That took a lot longer was a lot more litigious than the construction of the Central Subway.

I have a background project of exploring how to compress SMILES strings, which is a notation for storing chemical information. For example, "C" is methane, "CC" is ethane, "C=C" is ethene, "CCO" is ethyl alcohol, "C1CCCCC1" is cyclohexane, and "c1ccccc1", which contains aromatic carbons, is benzene. The average length of a SMILES string for real-world molecules is about 50 characters.

I previously evaluated a special purpose tool which identifies the best n-grams and uses dynamic programming during encoding. That gets about 70% compression on SMILES string. I also tried the off-the-shelf femtozip which got about 60% compression but had more decompression overhead than I like.

Shoco, trained on 1,455,763 SMILES strings (average of 56 letters each), and tested with 100,000 strings from the training set, reports "average compression ratio: 47%".
