Air is a pretty bad transport agent for heat compared to water. To heat a house (and especially poorly insulated ones) the air either has to be rather hot or flow pretty fast. The former is not very comfortable because of the large temperature gradients and it can cause a 'scorched dust' smell. The latter is also not very comfortable when you're in the flow path, it's noisy and the increased flow of air in the room means more heat is escaping to outside.

It can work for well insulated and airtight houses but I'm not a fan (pun not intended) because you're tying two different functions (heating and ventilation) together.

I think this policy makes a lot of sense--it's best to ban editorialization of headlines altogether as there's no good objective way for mods to differentiate bad editorialization (sensationalism, inaccuracy) from good editorialization (adding pertinent information, clarifying, and de-sensationalizing).

However, there is also a strong argument to be made that there are good articles with lame titles (such as this one) which would otherwise be glossed over without a title change. Maybe the best solution would be to add a summary field to submissions, restricted to an 80-character, purely factual synopsis of the article's contents. It could show up smaller, beneath the submission headline, like a subtitle.

This way, you gain the benefits of editorialization (providing pertinent info highlighting the article's appeal to HN readers) while minimizing most of the downsides (loss of info provided in the title, misconstruction of the author's intent).

Shanky, not the kind of experience you'd have known Ola for. There could have been some cases of a few inconsistent experience coming your way (surely a function of scale), but that is minimized to a very large extent with aggressive sourcing of feedback, audits and quality checks. As such, Ola doesn't face such issues since it's focus is towards creating micro-entrepreneurship opportunities for drivers (who own their cars) and work with Ola purely on a commission basis, but in adherence to strict quality measures.

On a side note. if you have had a bad experience(s), do share up your CRN on feedback@olacabs.com. The team is generally quick to resolve.
Yeah, don't trust this guy (vasco), he just deleted his comment and run away with my stellars. Total douchebag. :D
I think your latter point is part of my confusion. Is this a proposal for what PHP should be or what it currently is?

As I understand it, the Samurai live by the 7 virtues:
- Rectitude
- Courage
- Benevolence
- Respect
- Honesty
- Honour
- Loyalty

I wouldn't be surprised if these virtues continue to play a huge role in today's society. That said, I'm also not sure how serious people live by these virtues.
Excel had major issues with statistical calculations prior to Excel 2010. Post 2010 there are still a few issues. Have you taken this into account and corrected any, or just duplicated the behaviour, or some other method?
Real pity. I loved the beautiful photography the app provided. It made me want to travel more. Maybe they should have work with the travel industry to make bookings available. Oh well.
Definitely excited. If they win that bid, prepare for some shake up down the line.

Their strategy is to provide service at a fixed, fair price: No options, all included. Although they provide additional services, it's an ISP that actually knows it's a dumb data pipe: on broadband, you get the maximum bandwidth you can have; on mobile, data is data, so tethering is bundled. They were the first to provide native IPv6, FTTH, Gbps ports, etc... to end users. They definitely like to try out new tech (e.g they have additional compression and error correction on their ADSL2+ system, that provides a boost to throughput and stability).

They leverage FOSS products to integrate them into their architecture. For example, their set-top box is an AirPlay audio and video receiver. Back in the day they provided free FTP and web hosting (basically Apache and vsftpd) to their users, along with 1GB of IMAP mail storage when everyone was stuck with a dozen megabytes and POP. On the whole, they have a tendency to please the tech tinkering crowd, the router having features often found on homemade Linux NAS or Sinology systems†.

They regularly stand up for their users. When they were legally required to provide personal data from IP adresses, they did so in the most unpractical way possible (IIRC printed out via fax or snail mail). Recently they refused to pay for unbalanced peering, resulting in slow Youtube performance.

On the bad side, they're known to sacrifice stability to reach the price target, knowing that things will improve later as the system stabilises. Their service usually works well but they often have trouble scaling up to match demand, up to when the demand stabilises and they're finally able to catch up. Customer support used to be weak but has greatly improved. On mobile, SMS suffered delays and delivery issues††, calls failed to connect, power consumption was higher (I bet a failure to negotiate proper power profiles with baseband), but things have largely stabilised. IOW, they release early and often.

† but NO STATIC ROUTES. Seriously.

†† actually left for that reason.
(... nothing like the horror stories coming from the US).

I've had really good experiences with Tmob customer support, so I get aprehensive when there is acquistion talk.
> but is excel speed a common problem for people?

Anyone who sets excel to "manual calculation" mode to avoid pauses whenever they make a change in a big spreadsheet might be interested in this. If this engine removes the need for that, it could be a pretty big deal. It'll definitely make things easier for me when I'm messing with material testing data.

But like you said, how do you market it? How do you reach the people who need it? I suspect that for most people excel is just a tool, and they're not involved in excel communities or excel culture (if such things exist) in a way that would allow them to discover something like this.
The reason is strictly for fundraising. They have Naval Ravikant as an advisor and he is a proponent of using that model to fund a project. It's a viable model, but I don't think you can call yourself a nonprofit and use it.

I work at Stellar. re: the distribution method: mining obviously has many benefits, but it's still limited to people who are highly technical and/or who have money to spend. That eliminates most people in the world. We wanted to provide much broader access to digital currency to normal folks, and so stellars will be given away for free at the click of a button. Hope that helps clarify.

Read my comment again. I said that in the context of the exact laws and regulations you rail against. Obviously, there will always be a need for low density development, especially with a growing population. But the modern suburb is defined by restrictive ordinances that prevent high density development.

I think it's a matter of definitions. Demographically the countries are actually more similar, there is just differences in how people identify. The biggest difference between the two countries and cultures is Uruguayans are secular both in personal culture and with regard to the state. Where as Argentines are Catholic. There's also a big difference in political culture, structures of political parties and faith in institutions. Uruguay has much less corruption.

Hi, I don't blog regularly.

Would make my day if someone more experienced could comment on my blogging style and give me some pointers on how i could make the post more useful or interesting.

Thanks :)
Just checked out the docs, looks like they have an easy call to mark one/multiple articles as read - so could have something running periodically filtering out stuff you're not interested in
This won't work. Both 0 (numeric) and '0' (string) == false, but never === false (because when you === you're checking that it's the same type).

If you expect a string '0', simply check strlen($str) > 0. If the value could be numeric, use a (string) cast.
Could be my mistake, I didn't see a screenshot, maybe I'm blocking something
There's a difference between "having a destructor" and having a first-class representation of it. For instance, basically every language has a destructor for booleans—it's just if.

The trick is that unless you have first-class functions you probably cannot reify such a destructor. It always just lives in your syntax.

On the flip side, that's really what it means for a language to, say, lack sum types. It's not that the language doesn't have the ability to have choice, it's that it lacks the ability to represent choice in data. In other words, you probably can eliminate choice using if/switch/case/what-have-you but you can't construct it.
If you really want to test for empty strings where $a is defined just use:

if ($a == "") { ... }

Empty is merely the function equivalent of the not (!) operator. The semantics are exactly the same except for the handling of undefined variables. It's not something one should use except if you're expecting to deal with undefined variables.

It's so friendly that Uruguayans and Argentines don't identify the other as foreign. Uruguayans didn't want to be their own country when their started their independence war, it was an attempt to not be part of Spain or Brazil and to be joined with what would become Argentina. It was the British who decided Uruguay would be an independent country. Since then in the last 200 years, they've developed somewhat distinct institutions and cultures. It's similar to the relationship between the US and Canada.

In the UK, speed cameras seem to be accompanied by road markings:

http://southport.qlocal.co.uk/southport/news_list/New_Speed_...

I always assumed that the radar was only for deciding to take and submit the pictures, the actual speed measurement (especially if challenged) would be done using the markings on the road.

That only requires the speed camera to have a reliable to 1/100 second clock which isn't exactly rocket science.

That's not true, empty() will call __isset() first, and only if it returns true will it call __get().

This is because empty() is the compliment to the isset() function. There is no reason to use empty() over the not (!) operator unless there is the potential your property doesn't exist.
How does Alloy make Titanium less promising? From my experience, it's been a strong step forward in productivity and code management.
It would be possible to do that, yes. But we didn't want it to turn into a set of options/plugins for varying industries. It's also an issue of resources. We're a 3 person team and we need to focus our efforts accordingly. Deciding to do just restaurants has made it easier to prioritize and delegate tasks.

I understand it could rub you the wrong way to abandon other industries. Trust me, all of us shared the same feelings.

In short, the approach we decided on was to first dominate one industry, the restaurant industry. If we become successful at one, maybe then there is a possibility to look at others. But focusing on several industries will always leave us being the 3rd or 4th best at scheduling for that industry. It's hard and nearly impossible (given our size) to be the best for every industry, and we want to be the best.
This works fine, it just suffers from boolean blindness.

I love the implicit assumption that the standards-of-the-moment are any better. The only useful current HTML standard is "does it render in webkit." I can't even count the number of websites that can't render at all on devices even a year or two old (looking at you, Forbes).

This whole 'effort' is moot since web practice veers so quickly that we'll be back in the same boat by 2020.
This reads as a little conceited or else disconnected. I'm not saying I don't disagree, because I believe that MOOCs are probably better as a supplement to college, but another fact remains that some of us don't have the same opportunities to go to those same hand full of colleges. In other words, I think a huge part that is missing from this is the discussion of inequality.

MOOCs are not going away any time soon. There are professors and educators definitely taking the time to create quality lectures and make sure you get the help you need, and I don't think that's much different from attending an actual college. The only thing missing is probably the importance of human interaction.

Also, I'm not sure about that math because even he seems skeptical about it. Hope somebody can help enlighten me.
While the article may be correct that MOOCs will not achieve the oft-stated outcome of displacing the current higher educational system, I think the argument that the author is making regarding the affordability of college is off base.
Harry Lewis in the article states: "At Harvard and a handful of other schools, nobody graduates with any debt (unless they have intentionally borrowed so they could avoid making money in the summer, etc., and even then the amounts are likely < $10K)."

While according to Harvard itself: "The total 2013-2014 cost of attending Harvard College without financial aid is $38,891 for tuition and $59,950 for tuition, room, board and fees combined."

Unless summer+part time work is a lot more lucrative than I am aware of, the only way this would be true is if the students (or their parents) were financially well-endowed. A student that doesn't have rich parents is going to be incurring a fair amount of debt or spending way too much time working instead of studying.

Edit: Harvard is generous with its financial aid, so the author's message is more accurate than I understood (at least for Harvard). Learned something.
If, like me, you had some trouble wrapping your head around how the conditional operator ?: was being parsed, it may be more apparent while looking at the equivalent Scheme:

> (define initial 'J)
> (define name (if (if (if (if (eq? initial 'M)
'Mike
(eq? initial 'J))
'John
(eq? initial 'C))
'Catherine
(eq? initial 'T))
'Thomas
'unknown))
> name
Thomas

Notice that the "then" clause and the "else" clause have two different types for all but the outermost if. The "then" clause is a symbol, while the "else" clause is a boolean. Furthermore, if the "then" clause is taken, the resulting symbol is considered truthy by the if operator. So, the innermost if expression evaluates to true, then, moving outward, we get 'John (which is truthy), then we get 'Catherine (which is also truthy), then finally we get 'Thomas, which is bound to name.

PHP's truthiness rules are different from Scheme's (and are far more complicated), but for this particular expression, the net result is the same.

For comparison, every other language with a ?: operator behaves like this:

> (define nom (if (eq? initial 'M)
'Mike
(if (eq? initial 'J)
'John
(if (eq? initial 'C)
'Catherine
(if (eq? initial 'T)
'Thomas
'unknown)))))
> nom
John

Which is far more useful.

"If so, then doesn't it have all the same problems and concerns as Ripple?"

Correct. Like Ripple, Stellar requires special (and dangerous) trust in certain nodes. For example, gateways (https://www.stellar.org/blog/introducing-stellar/#gateways) have to be trusted by the Stellar network as they send messages like "a user deposited 100 USD via a bank wire transfer, so please accept this digital representation of 100 USD, trust me". This trust is dangerous as people running an (initially) honest gateway may start acting maliciously and lie about how much USD or EUR or other currency exist on the network. By the time the malice is detected, maybe the network could trace all USD or EUR that was issued by the gateway, and revoke it, suddenly pissing off a lot of users who owns this currency as it would disappear from their wallet. Users would then loose trust in Stellar, and the network would collapse...

Stripe would presumably be the first gateway trusted by the Stellar network. Okay, so what if Stripe decided they could not trust other gateways and wanted to remain the only gateway? Well Stripe would be the only way to inject USD or EUR or other currencies in the network, effectively making Stellar a fully centralized digital currency, with the entire Stellar network being dependent on Stripe not being hacked, not being abused by a malicious employee, not shutting down, etc.

This is the complete opposite design principle of Bitcoin which requires absolutely no trust in any specific authority.

They could hardly wait for the Rabbi to answer their urgent queries." Continued...http://basicindia.typepad.com/basicindia/2005/06/the_rabbis_...
Teamwork!
True. Though of course you also need a certain set of competencies to hold a "guaranteed job" (or it ceases to provide much meaning, if it's just something people maybe show up to and don't get any work done), and if you have sufficient competencies then the guarantee is less necessary. All of that demarcates a region in person-space. It might be a region where there are a ton of people; I'm not convinced that it is, nor that those people aren't better helped in other ways (including, possibly, a BI that lets other people find meaning other ways, letting these people do that work).
