So you're talking about TCP slow start here? In that case, yes, I agree that in theory compressing the headers is potentially useful, though for a well-organised site I wouldn't expect it to make much difference in practice.

You do have to try quite hard (or be careless with things like cookies) to get the size of a single request above the MTU for typical Internet usage. Chances are that in practice you are going to be requesting an HTML resource first, then probably prioritising some CSS, then JS, and then other resources like image or multimedia content. And for the responses in each case, the size will usually be dominated by the payload rather than the headers anyway. So it seems likely that in such an environment you'll be more limited initially by the response time for the HTML and the main CSS resources anyway, or by general packet loss on an unreliable network.

By the time you've got those initial resources, parsed them, and started requesting the supporting content, you've probably warmed up the TCP connection enough for slow start not to make much difference any more. Beyond that point, effects like multiplexing, prioritisation and server push seem to have more potential for increasing real world performance by reducing or eliminating certain round-trips at the HTTP layer. (This assumes that the browser and server do actually take full advantage of these new options; there seems very little discussion so far about how we might achieve this in general.)

For me, it greatly depends on the location. At locations where hostels are readily available and cheap, I had easy time couchsurfing, e.g. Mexico, and had a very good time (that was last summer, 2014). In SF, yeah, good luck, and better be a handsome girl/guy (and maybe get some unwanted advances).

Though, actually, back in 2010 I did find a CS host in Brooklyn, NY within maybe 5-10 requests, so YMMV.

Israel, I've been told by my guests, is very easy.
Well a lot of coursera courses come with :

- a community where you can discuss courses like in a real class

- exercises,source,... that are often reviewed by real teachers or peer-review which absolutely invaluable at least for me . I learned a whole lot because of this.

So it's way more than a youtube channel with a bunch of videos. Course are shot specifically for coursera.
I think the regime that you're under would be quite an improvement to here, which is chaos. Crashes were not common, the situation on the road was orderly, almost everyone followed the rules perfectly.

I have been (and still am) using a Pangolin Performance for a few years.

I like:

- All versions of Debian and Ubuntu work flawlessly (no pre-purchase research necessary)

- Sturdy (knock on wood)

- Easy to take apart (for cleaning or upgrades)

- Nice screen

- Keyboard with numeric keypad

I dislike:

- Very rarely (once in a month[1]), the touchpad acquires consciousness.

I am neutral:

- It's not silent but I did not expect silence when I purchased it with the latest i7 at the time.

POJO just means a class that doesn't extend a framework class or have framework annotations. The opposite of a POJO would be something like an Enterprise Java Bean or a Persistence Entity--which are configured via XML to subvert the type system as you put it.

I'm fairly new to Haskell and the type system is still a little scary to me, but learning it feels like a much better use of my time than memorizing the GoF patterns of Java.

Funnily enough, I too have often wondered about that.

I've also often wondered why your gender is the state's business at all. One way to make the whole gay marriage thing a non-issue would be to say it's nobody's business what you have between your legs, except your doctor and your partner.

There are a couple of scenarios where it would be an issue, like if you go to jail and there are no mixed gender jails, but it's likely that a little bit of imagination would fix that.
Yeah, its even a bit slower since it doesn't appear to be using multiple workers.

Slightly OT, but I found that you can detect the number of available cores with "navigator.hardwareConcurrency", but unfortunately that includes HT threads, at least in Chrome on OSX, so it says 8 instead of 4 on my machine. Is there a workaround?
What if someone opened a for-profit prison in the US that focused on rehabilitation? The prison could start by bidding on incarceration contracts for non-violent drug offenders. The prison could take notes from the Scandinavian system:

* Humane housing
* Counseling
* Family visits
* Emphasis on self-reliance

To help reduce the costs of the prison, the inmates could produce something that is very labor intensive and hard to create without cheap labor. Farming? Food production? Laundering uniforms? QA testing for large software companies? (Only half joking.)

Without the political clout that the Corrections Corp of America has, I bet it would be difficult to bid for contracts, but it's a more realistic way of making a change than political pressure.
Your quoted comment came from me (I'm the author of the above comment as well), the CEO of Judicata.
Did an employer ever ask you to show them your university degree after you mentioned that you attended an university on your resume? I'm asking because it never happened to me and I don't think it's a common practice. Just mentioning that you have done some online courses on your resume and being able to talk about them seems enough to me. If the course is relevant to the job you are applying to, I expect the interviewer to be able to verify that you indeed took the course in a quick conversation.

Inherently? No.

Work programs where the pay is a tenth or less that of even minimum wage, though, are easily abused.
The personnel manager (again: they usually have few knowledge about the topic) is usually not able to assess whether these projects were really difficult or just smoke and mirrors.

Distributed auto-routing smaller busses should cut costs drastically, so this should be very feasible either if implemented commercially or as a commercial service.

I have to imagine that paying the bus driver is generally the largest cost for a single bus in any given public transportation system, and being able to route directly during periods of lower traffic (or high traffic even) should be much more efficient in terms of time.

Hell I bet Uber could implement scheduled ride sharing and be competitive with public transport on cost now in many cities. 4 people get grouped with the most similar commute and split a $15 fare? That gets you pretty close.
I don't know much about web workers. According to my understanding, they can only communicate by message passing. This means that, if I have a 50K array and wish to sort it via a web worker, I must copy it twice: once incoming and again outgoing. This copying is likely to be as expensive as sorting it (well, maybe not if you use bubble sort). How do you mitigate this?
I heard of these issues too, on Reddit. After my experience with their support people, I decided that the issues were either an active social media PR campaign against them by one of the other vendors or regular mishaps of the support department or a combination of both.
Coursera has increasingly pushed non-participation in a course's verified certificate process as a signifier of lower status as a student. Originally, certificates were a mark of academic performance and the business model was more akin to a dual license open-source project where the non-paying community was just the non-paying community; the verified certificate was solely a value added proposition based on the value of verification. The change has been that certificates have shifted toward a mark of consumer status.

There has been a trend toward attaching stigma to taking the courses for free. Removing the certificates from free tracks is an obvious part of it.

Scaling objects doesn't preserve their ability to withstand forces: for example cross-section areas scale with square of scaling factor and masses/weights scale with the cube of scaling factor; so objects are close to collapsing due to their own weight if you scale them up.

Could it be a prisoner's dilemma of sorts between states? If one state introduces prisons along the lines of those described in the article, then criminals will flock to that state because it'll be known as the one that has nice prisons.
It's absolutely ridiculous that this type of functionality isn't a native part of Excel, I was doing something recently in Excel that should have been trivially simple but because of the lack of obviously useful functions like a multi-column VLookup or Match function, the hoops you have to jump through are insane and brittle.

One thing I hope changes with Microsoft's seemingly new culture is this deliberate crippling of product functionality so as to not cannibalize revenues from other projects. Another good example is MS-Access - such a highly productive environment, but some fundamental shortcomings in the design make it totally unsuitable for projects beyond a certain size.
I strongly recommend you update your web page title to say the same thing, otherwise the mods here may adjust this title to match that one.

So divide the jurisdictions to where they're manageable. We already do this - each state runs their system independently, just as each EU member state does instead of having a single European prison system.

I have no non-Coursera CS training, so I use it as the "CS training" part of my resume. (I also have relevant work experience and a math degree.)

I would be comfortable hiring someone entry-level most of whose relevant experience was from Coursera, assuming they convinced me they would be a good hire.

If you are a quick learner, IMO you should feel comfortable applying for any job you think you can get hired for, even if it's a stretch based on your experience.

> COPPA affects all websites or services even if you don't target them at children.

I don't believe this to be true. I am not in anyway a lawyer (so please consult one before taking my advice), but I've got a fair degree of experience making COPPA compliant products. For a site or service to fall under COPPA rules, it must explicitly be "directed to children" (https://www.ftc.gov/tips-advice/business-center/guidance/com...). There's a little ambiguity about this term (which is ultimately resolved in court, I suppose), but you can read a little more on that FTC FAQ. It seems to be quite reasonably applied. I also believe if kids self-host their own servers in a Minecraft game, Mojang/Microsoft can't reasonably be accused of storing or sharing PII. It doesn't get near any company owned servers.

I also used IM services and chat rooms as a child, and came to no particular harm. Many, many children use those services everyday and also don't come to harm. Some do. I don't think that has much to do with COPPA. COPPA shouldn't apply to MSN and generic IM services. MSN and the like aren't directed at children; at least I can't see any evidence that would lead someone to believe that children under the 13 are the "primary target audience" for MSN, which triggers the COPPA requirements.

> Re: sex offenders. COPPA isn't about that, is it?

I think it is, yes, amongst other things. One of those P's is 'protection' - whether that's protection from exploitative marketing or groomers, it's about keeping children safe online. Making something explicitly for use by children is very different from making something for use by the general population, and you have a different kind of responsibility as part of that.
ISTM that a fleet of self-driving cars will serve everyone it can. Every car will try to stay occupied as much as possible. Perhaps this means that service will cost a lot during Friday rush hour and very little at 4 AM on Wednesday. In that case the poor may just decide to travel at nontraditional times.

[EDIT:] to clarify, the phrase "just decide" is more of a medium-term phenomenon than a short-term one, and elides a great deal of noteworthy human experience. Of course, being disadvantaged often means one can't make sudden changes to one's routine. The poor are not stupid, however. When using short-term self-driving cars is cheaper than owning "clunkers", they'll sell the clunkers and figure out how best to integrate self-driving cars into their lives.
Roundabouts with unbalanced peak flow traffic can be impossible to enter if a previous entrance has a near-constant peak traffic flow. At rush hour they basically break under this condition. You could mildly gate them with lights to fix that, though.
I did a couple small projects in OCaml and I loved the syntax and style of programming, but I think there would pretty much always be a better language choice for a serious project, regardless of what type of program you are writing. Also, the standard library leaves a lot to be desired and parts of the ecosystem (e.g. docs, and OPAM) are pretty rough. The standard library has a lot of gaps so you end up implementing a lot of low-level functions that will seem tedious and inefficient if you are coming from a more mainstream language with a rich ecosystem. Using the Jane Street's Core library helps a little bit but still leaves a lot of gaps. It's still a fun language though, but I don't think there would be a compelling reason to choose it nowadays for a new project.
fair enough.

I haven't had many of those myself - but that may be a selection bias due to not having accumulated credentials. Have to admit, no body has ever asked me to prove I went to university but they have consistently asked for the types of answers I describe in scenario #1 above.

In the case of the hiring I do, our "personal managers" are code surfacing resumes based on their content and then a lightweight screening before they come to me. That screening might include a check to verify experience or references.
Then I never ask for credential -- only discussion and proof of work (again - maybe a bias of me and those like me).
Roundabouts are for humans. You can have a four way intersection without traffic control if all vehicles are fully automated; they each know when they can proceed and when to yield, with no need to wait on other vehicles except when a conflict occurs.

HBS Class Day 2015: Scott Cook
Since they are paid less than minimum wage it's unfair to external workers and should be illegal. If they cost less than non prisoners to employ and have their food/housing subsidized by tax payers - no one will ever compete for the same jobs. It's nearly-free labor for companies subsidized by everyone else.
The fascinating thing about SD cars is that actually, they don't need to pre-map routes in excruciating detail. They carry enough sensing equipment (the primary being LIDARs) to build high detail maps on the fly, along with recording the location of other road users.
Low-detail, pre-mapped, road maps are mainly used for routefinding rather than second-to-second navigation.

> Did an employer ever ask you to show them your university degree after you mentioned that you attended an university on your resume?Did an employer ever ask you to show them your university degree after you mentioned that you attended an university on your resume?

I live in Germany, so I can just answer this question for Germany and Austria (in the latter country the situation is even a little bit more expressed). But handing in a copy (often even a witnessed copy) of your university degree is nearly always required when making an application even to get an interview.
The problem with the argument is not that it's not worth raising alarm about 6%. It's alarming--that number was basically 0% 20 years ago. However, the argument doesn't explain how our justice system got to be the way it is. Private prison corporations didn't create extreme minimum sentences. They came along after the fact to profit from them. The core problem is a lack of virtue in the American people. We're unsympathetic, unforgiving, and unmerciful. our lack of virtue created the system that opportunists are now profiting from.

In the USA, sales-tax is deductible from your income so you're not required to submit to double taxation.

More important than pressure differences, is the circumferential stress on the fuselage/can, which is what the walls are actually withstanding. For a pressurized circular container, it is given by p*r/t, where p is the pressure, r the radius and t the wall thickness.

If we consider a 3 m wide airplane, with a 1.6 mm thick fuselage at cruise altitude (around 40k feet), you get around 56.5 kPa of pressure difference, and the above equation gives you approximately 52 MPa. (data from a real aircraft that I cannot mention).

For a coca-cola can, internets say 380 kPa of pressure, for a 6.6 cm diameter can, and 0.15 mm aluminum sheet. That results in approx. 85 MPa.

So as you can see, even though you have roughly 7x more pressure in the soda can, its much smaller diameter severely reduces the stress on the walls, resulting in about 1.5x the circumferential stress.

Hope that answers your question.

edit: several errors in my back-of-the-envelope calculations. sorry.
The change is not in charging for value, it's in removing the value from the alternative. It's got some equivalence to a company with dual licensing open source software crippling the community edition in order to sell more of the commercial edition.
good point. I've also lived in non-US countries and saw that.

So question for you is - in your country is the need for the certificate increasing or decreasing?
Regardless of club affiliation, generally speaking it makes no sense to have women stand up for men's rights. Men need to stand up for men's rights because then at least you can assume authenticity based on shared self-interest. In that respect, even MRA is, for men, an improvement on feminism.

I don't mean to single out your comment (the core idea of which I agree with), but I see similar comments on HN a lot. Completely logical, technical observations that are also quite tone deaf. To those in poverty, there's often very little they can "just decide" to do. The ability to commute at nontraditional times is very much a luxury to most.
Seem completely normal to me. However the people who post on articles about criminal justice on HN are not a random sample of the population. The law considers punishment to be a valid role of the justice system, even though punishment should only consist of denial of freedom, and not being raped or killed by fellow prisoners or guards.
