What types of tests—or testing software—could be run on a WordPress site? For example, after we update a plugin on a WordPress site we manually check that the site hasn't changed in appearance. What software – or methodology – would you recommend for automating this game of spot-the-difference?

The nearest I've found (but not tried) are:

This is interesting to me... how did you go about finding the space?
If its custom, limited run, or high demand, you'll pay at least MSRP, depending on how many other people you're competing against for a small pool of vehicles.

You're referring to the dealership's working line of credit, which is just interest they pay monthly from time of vehicle delivery to sale. For most vehicles, this amount is negligible (unless its been sitting on the lot for months). You could theoretically get a deal on a car they can't move, but the long-term resale value will likely be lower because its an undesired model/color/etc.
I think this will be great for the community. I didn't realize that you were involved as well Jon, should be interesting to see what comes out of it.
Google already explained why they chose Provo. The infrastructure is already mostly in place, and they can get it cheaply. http://www.provo.org/about-us/current-issues/google-fiber

Others in this thread have already explained why the NSA might build a data center in Utah.
The fact is current day parapsychological research is far more scrutinised than regular research in the social sciences, because of the controversial implications and because there is a large group of people that simply won't entertain the possibility of positive results.

The most prominent paranormal researchers employ far more skeptical rigour than other skeptical commentators who dismiss any finding. Because it's called "paranormal" the default is "there must be something wrong with the methods" and so naturally people find fault with the methods. Hypothetically, even if real paranormal effects are surfacing in the data, the nature of the research works against persuading certain circles.
Oh great, YO for the internet of things.
One thing that was the "killer app" for graphing calculators, at least through college in the last decade (even with wifi), was the fact that there were apps.

Graphing calculators were the first mass market mobile computers under $200 with what you could almost refer to as an app store, via ticalc.org (oh how many hours I spent on there). The interfaces had to be easy to use with low resolution screens and usually four directional buttons. Apps had to be about content. Games were pretty fun.

My TI-89 has survived 11 years. It's survived bike falls, being thrown across the room several times (when I was too quick to grab it and it went flying out of the cover). I use it infrequently but the batteries haven't been changed in over a year. I still have more screen real estate when I am typing on it than I do with my iPhone 5 (both in vertical and landscape). It has actual buttons and I have muscle memory so I don't even have to look at it when I type in numbers and symbols.

I have a periodic table app on my TI-89 that has been on there since 2003. The information someone in chemistry or physics needs is quicker to access than http://www.ptable.com or wikipedia. I'm sure there are apps on an iPod that are probably better now, but an iPod's batteries don't last months.

What could usurp it? Something in the same form factor that can last 48+ hours and take AA or AAA batteries. Something that provides temporary instructor override, allowing an instructor to enforce a policy temporarily (i.e. disable the CAS). Something that might integrate well with tools from TI that are out there. Something that's useful from middle school up to engineering/chemistry/physics.

Maybe something e-ink (and/or e-ink buttons), plastic, ARM or Atmel, Linux, python and some sort of CAS (Mathematica/Maple branded) by default, with an App store/ecosystem. Something $50-$75. WiFi only, but off by default. Something that probably looks a bit like a nokia n800 or blackberry. I think that would be reasonable.
Clearly the only scientific conclusion to make is that there is less magic in the world then there used to be.

In all seriousness though, having worked analyzing data in research, one overwhelming issue is that statisticians are often only involved in the analysis and not the experimental design resulting in studies that are plagued with noise and other confounding factors.

It is hard to know how this would effect a study of ESP etc since even a batch of non randomly selected people who could reliably do this would be significant but non the less replication has failed.
This company has a CEO, CTO, Chief Engineer and Chief Architect. With any luck they will be acquired by Google, Amazon or Apple for a billion dollars.
Do you have an api? I can imagine a bunch of ebay tools making good use of it.

Also, do you still use EasyPost?
Another crazy bias.
Google Tango is attempting to accomplish it by using the camera sensor to measure positional changes.[1] They showed it off at Google I/O, but it was a bit eclipsed by Cardboard (probably to the chagrin of the Tango team).

Rejecting subscription models
> With that said, they only charge a $5 fee for this service, which seems unsustainable.

From the article:

> Because it ships so many packages, Gibbon says Shyp gets significant discounts from the major carriers. This makes sense because pooling packages saves their drivers a bunch of trips. “It’s actually a lot cheaper for them to just go here,” Gibbon says. Meanwhile, he says Shyp charges customers the cheapest retail price they would pay to ship an item, which still ends up being more than what the company pays. Shyp keeps the difference.

As for paying the couriers: if they can pick up several packages in one trip, that could add up to a decent hourly rate. Large items that result in fewer trips will produce a large shipping cost, out of which Shyp could pay the couriers, while small packages will produce many fees for the couriers.
When you buy through the website, either in store or at home, the sale technically takes place in California.
USPS flat rate is actually only the cheapest USPS option if you are shipping > 11 lbs. I guarantee you that if you use us it will be cheaper (even including our $5 pickup fee) than for you to do it yourself with all free packaging materials. Then factor what your time is worth.

UPS ground and fedex ground are actually the best/cheapest option if you are shipping anything > 3 lbs. We choose the cheapest carrier automatically and create a custom box for each item.

btw CEO of Shyp here.

Kevin - What if Amazon, UPS, Fedex start picking up consumers items?

This appears to be your unique advantage which reminds me a lot of Instacart/Uber in a sense of bringing the solution to the customer instead of having the customer coming to you.
How does it handle feedback/errors? If I hit a button to execute a nontrivial task, I want confirmation that it worked. I don't care if it's a physical or digital button.
I dig the idea but the price point seems insane. I also don't quite understand why this needs to be kickstarted, why not just take orders and hand make the first N until you get enough profits to be able to mass produce?

I built a very similar button using an arcade button[0] and a raspberry pi, and it cost <$50 in total parts -- it would've cost a lot less if I didn't decide to use a raspberry pi that I already owned for it. Mine just does a POST to an App Engine URL, but since it's a real computer I can SSH into it and make it do absolutely anything on the planet too.

RE2 – a regex engine not susceptible to denial of service attacks
That effect should have been shown by now. I don't know of any studies specifically looking at this, but various global agencies require post-approval studies and monitoring which should have picked up on this.

Verizon Fined $7.4M for Misusing Customer Data
It looks pretty flimsy too, looking at the video. It seems like not that bad of an idea, but not nearly life-changing or revolutionary enough of an appliance that I'd spend $100 for it.

Most things that need buttons already have them.
This is when the really scrappy innovators, the lifeblood of the valley, head elsewhere.
Hmmm.

Not exactly what I was referring to. I would want a light to indicate some condition, then the button would perform some action. The two do not have to be related to each other.

So I walk in the house. The blue button on the wall is lit up, indicating that I have that email from my brother-in-law that I was waiting for. I push the button, launching a small nuclear strike against the country of Alfredamonia. (Or for a more prosaic situation, the light is lit up telling me my server is overloaded. I push the button to spin up another server)

It's a neat idea. 100 bucks is crazy expensive for something you should be able to order by the thousand from China. Going to need some serious early adoption folks. I would look to the Agile IT guys -- lots of those folks would want some big, physical indicator to show something and some simple way to interact with externalities.
its really about demand and pickup density. This is why we will launch in major cities first. We spend less than 1min on average pickup up peoples items. So once we are able to get enough demand within a close proximity everything works out great.
What cities are they in right now?
I would think it would be smart to do plugins for magento/woocommerce/presta/etc and let that trigger the orders. However not sure how this would work for moderate volume stuff that can't support the $5 eating into the margins.

This seems best suited for periodic sales off of ebay, not full time e-commerce plays.

It can use cell network but SIM is not included... so no data plan for the 100 bucks.

It's certainly interesting.

I was having this discussion with someone the other day. So far the IoT seems to be 200 dollar Locks/Lightswitches, 100 dollar buttons and academic research on how to handle 10 gazillion devices.

Something is missing.
"Shyp charges customers the cheapest retail price they would pay to ship an item, which still ends up being more than what the company pays. Shyp keeps the difference."

This could be very helpful for those that do not have a business account with UPS or FedEx, but if you regularly ship packages then it is cheaper to do it yourself at some point.

Amazon pricing:
http://services.amazon.com/fulfillment-by-amazon/pricing.htm...
Using their Action Toy example costs $6.54 which would retail $8-12 depending on the distance sent from FedEx/UPS

The spot that Amazon really excels is standard verse two-day shipping ($4.75 compared to $7.75 for a non-media item).

It would be interesting if Shyp or someone could graph the optimum depending on your volume (a bit complicated to due to sizes, weight and frequency, but doable).
I upvoted it, though I feel the pain on getting upvotes and reads on here. I think the last article I wrote got more upvotes on Lobsters than here. You gotta get just the right title at the right time, or it slides off the front page before anybody sees it.

I'm not sure what the best way to get going is. A webmail service dedicated to it would get the best UI, but there's the overhead of getting a webmail service with competitive features to Gmail, Yahoo, etc going and keeping it running. Or you could do a plugin or something, where it might be a challenge to put together a good UI and keep it in sync with Gmail's updates.
Or you could spend half as much

Well, plus the PC with wifi and gsm cards connected to that USB port.
Python – Taking Time with Delorean
That is one hell of a story.
agreed. a close second is the confusion between a published application and an issued patent.
Bayesians for the win!
For most "time machines" you read about, you aren't really going to run into the "CPT" issues from quantum field theory.

Unless you're considering a model of time travel where you're still literally in the same room and just living in reverse (while still visible to all the forward-living people around you and interacting with them as you go), this isn't equivalent to CP symmetry reflection.

Most time machine ideas instead picture some sort of wormhole or "stitching" between different points in space-time, in such a way that the local "forward time direction" remains continuous for observers taking the trip (and then connects back up with forward-directed time at some point in the past).

(I'm teaching a low-level course on "Time Travel in Science and Literature" this term. It's fun, but a challenge without using math.)

10 things I’ve learned working from home (~600 days later)
I dono; everywhere I go in santa clara, I pass big construction projects.

I think a big part of it is also the cyclical nature of demand. You know that big apartment development in sunnyvale near murphy st? it started before the big real-estate crash... then sat there, skeleton-like, for several years. It's done now, of course, and more are on the way.

I mean, I'm sure zoning difficulties are part of it... but the dramatic increases and decreases in demand have also got to have something to do with it. The business cycle here is shorter than your typical amortization schedule for a building. And yes, that isn't going to stop anyone from building on the upswing (if you structure it right, bankruptcy laws being what they are, you have a limited downside, and not much limit on the upside) - but when the cycle isn't "up" - people just stop building.
> That's exactly the purpose of the Comsat project, which integrates existing third-party libraries with Quasar fibers.

Indeed! :) And Comsat is a hugely important part of Quasar's growing usability in real-world applications. (I'm using the servlet & JAX-RS code right now. So yeah, it's safe to say I'm thrilled about those integrations.)

Quasar also has great abstractions available if one needs to generate new bindings to any code which can currently produce callbacks: FiberAsync [1] is every bit as simple to use as the docs indicate.

But it is still slightly-more-than-none work required when dealing with hollywood frameworks that haven't already been adapted. It's totally manageable; at the same time, it's my personal hope in the long run we see more frameworks growing up that deal with green threading naturally.

It's based on comment scores only. My sense is that it's an irrelevant distraction and we should get rid of it.

For example, we caught a bunch of users who were gaming it by deleting any comments that brought their average down. We fixed that by treating deleted comments as comments of score 0 for average-computing purposes. It's an example of how, once you publish a metric, people start to care about it and do things based on it, regardless of how meaningful it is.

Comment average used to be used by a few algorithms (like comment ranking) but we turned that off as an experiment a while ago and nothing seemed to get worse. If anything, I think it may have helped a little.
They already pickup peoples items. However they are not setup logistically to handle 5-20min pickup times. They do something called a milk run which requires them to pre-schedule their routes before hand. They absolutely could offer this service in the future, it would just be logistically very difficult to build it into their current operations.

Our unique advantage is our product/experience UX and our focus on packaging. UPS, Fedex, USPS and our other partners all love us. They see us filling a much needed gap in the market. Just as stripe does for visa/mc/etc.

What these shipping companies are the best at is moving many packed items over large distances. Their logistics networks are unparalleled to no one. We just see a large gap in the first mile.
They just copy/pasted the wiki engine, it's even showing "Wikipedia, the free encyclopedia". Looks like a really bad job. However, the Shield looks really neat and worth it.

Relay.js is a user friendly IRC client, see http://relayjs.jit.su/ for a demo. Converse.js (https://conversejs.org/) is an XMPP web client that supports XMPP conference rooms. So I'd say we already have good, nice-looking clients and there's room for improving integration on a single service to reach for the masses.
whats the cheapest if you are shipping 1 lb domestically and need a tracking number?
What hnriot says is pretty true. However, one of the points of using DDG is right on their front page below the search bar: "The search engine that doesn't track you."

As I said, the results can't be tailored to your needs. For instance: when I search Python how does DDG know to bring up? Python can refer to the snake, the programming language, the horror film, the missile, the sports car, the turboprop engine, etc.. DDG doesn't know what I intend. It can try to go off of popularity though, or I have to feed it more keywords for what I'm actually looking for.

Granted other engines can have this issue, but I think DDG more susceptible to this problem.
absolutely. The stuff we already do behind the scenes is quite incredible. Not ready to share anything yet but stay tuned.

I was talking about pure arrays of bits, as a theoretical construct, but you are right to notice that if not all your arrays are the same length, then each array needs to specify a length. 64-bit integers are like bit-arrays where each array is pre-defined to be 64-bits long and therefore doesn't need to store its length. You could define all your bit arrays to be 8 bytes long each and accomplish the same thing. Your better tact at shooting holes in the bit-array approach is not from memory consumption (you loose on those grounds), but you from a 'performance' standpoint, you can make the case the integer comparisons all take one clock cycle, and operations on bit-arrays are slower, because you have to check each bit individually to do logic. Summary: For storage size, bit-arrays win, and for performance integers win. So based on system needs you'd choose a solution, weighing the pros/cons.

Very nice summary of ZooKeeper, it is really an awesome tool for distributed systems.
Not as close as you think.

If it's not calendar months, then it is almost impossible to make actual sense of. If you wanted to limit yourself to 150 cars per year regardless of the start and end months, then you have to limit yourself to 12.5 cars a month which makes a whole lot less sense. Even still, at the day level you then have to restrict yourself to 0.411 cars a day. Then the hourly level...

Things are made simpler if you aren't close to the limit, but what is the purpose of expressing a limit if you aren't intended to get close to that limit?

for example, let's say you have this sequence (assuming the law is 150/year regardless of calendar months:

12.5, 12.5, 12.5, 10.5, 14.5 , 12.5, 12.5, .....

Boom, you're over if you continue to sell at 12.5 a month. You can compensate for the 14.5 by having another month of 10.5 within 12 months of the 14.5 month, but then you are under the limit within a different 12 month period and can/should have another 14.5 month to make up for it. The pattern repeats itself...

The overall point is that this would be a very stupid way to express a limit and it is far from logical to interpret it that way.
Which twenty states?

1. North Carolina

2. Tennessee

...And 18 others, according to the Netflix comments document. But, I don't see a list or a description of the laws.

For context: my goal is to find out if such laws exist in either Nebraska or Illinois (Chicago) and if they do, what are the specific restrictions. I want to find out what legal hurdles I might face if I attempt to build large router<-->router mesh networks.
Very cool idea!

Unfortunately, doesn't look very easy to get into. I'd imagine quite a few people applying to it. So the odds of someone like me getting accepted is probably near the bottom... i.e. Not connected, not a social-media evangelist, no github account, etc.
That's a fair comment. One can't assume that an equal dose per kg will translate reliabily from an animal to a human.

My only reply is that the BSA method of dose conversation has issues of it's own (referred to in your paper) with regards to drug metabolism.

Also, the focus of the paper is on dose translations from animal to human studies. One would obviously want to be conservative in that regard.
Yes, the market is shifting towards affordable smart devices, but there is still a lot of fracturing that makes development hard enough even for premium audiences.

I think that finding this classes problems, a good solution, and mapping them to software is the real problem -- the device proliferation and connectivity is just a compound issue.

There are others that believe the inverse though, devices and connectivity proliferation are the primary problem and solving it will allow for the next generation of startups to address this classes real-life issues without the hardware overhead.

Every time I see stories like this on HN I am very tempted to scream about how my burn rate is $700/mo living a very good life without too many distractions from my work. I cannot imagine why people would lace up with lead boots on their first venture by trying it in SF.
Absolutely not true. As the article points out we actually make our money from the price arbitrage between retail and our discounted shipping price. The $5 covers the pickup of an item.
I agree. I would love to see what plasma concentrations were achieved in the mice at each dose and compare that to what is typically seen in humans.
