before this article i didn't want to touch scheme macros.

he does a great job by introducing macros using basic syntax transformers, every other tutorial failed for me by introducing define-syntax-rule before explaining how it worked.
IANAL, but a company claiming that you give up your rights is not the same thing as you actually giving up your rights.

All these companies are essentially doing is claiming that you are giving up your rights. It remains to be seen whether these provisions will actually hold up with legal force in court (I doubt most of them will).
And the content of the first block may be unreachable all the time, depending on the implementation of Eq. But you probably have a number of issues to worry about if your implementation of Eq doesn't work for the identity case.

I think the most fundamental advantage is that Photoshop was designed to edit photos, whereas Sketch is clearly built for UI design. Because of that, it has the tools you are more likely to use in the right places and has a lot of built-in features specifically geared to designing UIs.
You know you have an interesting article when the #1 comment has been deleted.
I have stuff with them, Rackspace, and Heroku depending on the task. Usually they get the lowest trafficked, most static websites.

I feel like their support staff could use a boost, but they're OK otherwise.

If you aren't getting a lot of traffic, I'd also recommend https://www.nearlyfreespeech.net/ Which has been nothing but wonderful to me for very low traffic sites.
I like the idea but search on YouTube seems to be so inaccurate I'm not sure if it would work nearly as well.

I'm having trouble thinking of how to improve scInstant as it is--it's so pared down and fast and just works! Great job!
I'd say there is zero learning curve. So much easier to get started for anyone new. My favorite thing about Sketch is the ability to use Pages and Artboards + Symbols for multiple screens design. That's the way I prototype nowadays; focusing on interactions and flows rather than static single screens and branding/image editing.
Seeing this article is rather bittersweet. I came to a similar conclusion in my college years but I never pursuit it further.

Taking Quantum Physics in college was a life changing experience and it reshaped how I viewed the world. I was always obsessed by time and one afternoon it became clear.

I explained my variation not as a cup of coffee but a handful of dice. Essentially every tick of time is rolling these dice. And the variation of dice from one combination to the next is the arrow of time.

Like one of the authors in this article, I got the most amount of resistance from physics major. For most part they had a dogmatic view of anything that they had not studied yet. If it wasn't in their books then it didn't exist.

I also came to the conclusion time travel as depicted in the movies will never happen. It can happen randomly in a smaller body but for anything large the arrow of time is almost impossible to reverse.
> Doesn't work with IE

That's not true. IE has supported it since IE9 at least. http://msdn.microsoft.com/en-us/library/ie/cc304078%28v=vs.8...
Sometimes what bothers me is I sometimes have no idea if a query is slow or not. This holds more true since I've been developing on Rails with Postgres. With MySQL it seems the bottleneck queries seem a lot more exponentially progressively degrading in correlation to the amount of records in a set.
With Postgres this seems to be a lot more linear.

I have just made some crafty work in rails to make use of hstore datatypes in Rails. It stores an array of hashes, which I have not found a way to index the keys of yet.

Is this slow or fast for example?
I'm doing a full-text search over all unnested (hstore) array values over a given column in a table wih 35k records.

development=# SELECT "leads".* FROM "leads" WHERE ( exists ( select * from (SELECT svals(unnest("address"))) x(item) where x.item LIKE '%mst%') );

Time: 57.257 ms

I'm used to MySQL, and this kind of query over unindexed records seems fast, but it also seems this might be slow for Postgres standards ?:/
Bear in mind.. no indices.
I'm glad you like it. Feel free to send any PRs. As long as the UI isn't bloated, I'm happy to merge. :)
Some other downsides:

(1) Store gets to guess on what to do if your item isn't actually in stock - you can provide a bit of guidance, but sometimes the replacement is bad.

(2) Sometimes groceries get delivered with really aggressive sell-by dates (like one lb of ham slices that's got 3 days of shelf life left)... happened on a Safeway delivery.

(3) Occasionally I thought I clicked through and didn't, and other times one of my credit cards has a hold (fraud alert) or has been cancelled (thanks Target!) and the account still has it. (this happened a couple times with Google because they don't charge your card until your delivery is on the road).

Strangely I haven't noticed a significant price increase vs. shopping at stores.

It was only recently i had the pain of looking for a Cloud Storage solution and none of them seems to fit my needs / taste / price.

Yes. Whenever i see unlimited i dont even look further into it. Well unless they are from big companies like Microsoft or Google which could actually afford to do it. Otherwise they dont have a viable business model. And i am weary of that.

I dont (quite) trust Google. And Client of Google Drive just somehow doesn't really suit my taste either. Skydrive is expensive. Dropbox client is the best, but i cant bring to myself to pay 5 times the price. Hubic has crap interface. I am looking at MediaFire and Bitcasa, but both previously had some bad reputation with it. Copy from Barracuda looks like best candidate at the moment.

I have my own NAS at home. 2x2TB Synology. But I know my home's power delivery quality isn't that great. Power Surge and Lighting are things that could easily destroy your NAS or Data even i have Raid 1 with another external backup. Having something in the cloud just removes the hassle of doing it yourself.

I have been dreaming lately of a NAS that does it with Backup in the Cloud in one go. And i just pay an initial fees with a monthly fees. Hoping Apple would do one. But since margin is so low i guess they are not interested.
hey kiro, there's a lot I like, but probably the best thing is that I find it fits the process that goes on back and forth between designers and developers. It's really good for that. Few other things:
- small team (4) that are pushing many builds a day
- really easy to slice and export e.g @2x and 1x
- vector, so easy to scale up and down
- lightweight
- super active community releasing plugins and resources.
- it's cheap.
- lots of good learning resources

I don't use photoshop anymore. really happy with it
I'll have three kids under 4, any day now. I can't remember feeling rested, either, but I've gotten used to it. I'm a professor and about to kick off a startup using free time over summer break. It's worse for my wife, I'm sure. For me, going to the office to work is my "rest".

It is generally hard to take James Fallows' opinions seriously. He is a great writer but always seems to be of the wrong side of history. For example back in the late 1980s he led the "The Japanese are Taking Over the World" scare just before Japan went into a multi-decade decline[1]. The fact that he is now worried about China puts my mind at ease.

He is much more credible when he simply quotes Stephen Chu. That much better batteries would change the world is not controversial. Actually making it happen is the tricky bit.

There has to be a better way than just floating in a grey area and hoping the courts agree with you.

I think the states need to set up some basic standards for how some of these agreements need to happen, and make them very clear. For instance, there could be a law that if you sign away your right to sue, it must be in writing.
Whatever the result, it will be tried, and probably by a huge company with the resources to push a verdict (or verdict-delaying settlement) through, to the degree that's possible. Worse things have persisted, but I don't remember this kind of cowboy tort-reform ever making headlines upon successful application. There are at least as many lawyers who depend on these suing rights to exist that can provide better pushback than any layman. General Mills has to listen to nobody except the courts.

I'm having a difficult time following his explanation. Here are a few of my stumbling points. Maybe you can help me out.

1) What does it mean that entangled particles are supercorrelated? How can S(A|B) = 2 or -1?

2) The formula for Von Neumann entropy is S = -Tr(p log(p)), where p is the density matrix. How do you take a log of a matrix?

3) Why does the interpretation rely on the density matrix? I've always thought of the density matrix as something that gives information about our ignorance rather than the system (this is why the density matrix mixes classical probabilities in alongside quantum amplitudes/probabilities - observer uncertainty is classical). Therefore, to me, any good interpretation of quantum mechanics ought to work without density matrices.

Unfortunately his paper here (http://www.flownet.com/ron/QM.pdf) doens't seem to have significantly more information than his talk.

Thanks for any help you can offer.

Electricity is an area where centralized is much more efficient and reliable, due to the economies of scale when dealing with larger load infrastructures. However, batteries close to the end point could definitely a useful thing, because the grid does work better when there is a constant load. It's easier to plan for both day-to-day activities, and if a plant does need to go down for emergency maintenance.
I don't think Chrome Remote Desktop lets you share a Linux desktop. I tried a few months ago and found it's a long standing (year plus!) request to Google on their support group. Kind of sad that Google can't or won't support Linux here.

Yes, I'm sure they just saw this on Nokia a couple of months back and were like "OH SHIT! We gotta do this NAO!". And then just 2 months later, behold - a perfect clone of Nokia's software (with stolen code from Nokia, too, no doubt, since Google is so used to "stealing" other people's tech).

These sort of things are usually worked on for years before release...And yes that was sarcasm, which I thought was deserving for such a silly comment.
Scanning through the first section, they've got the right idea, but the wrong rationale. The reason why the table is easier to read than the sentence is the spatial semantic grouping of variables. You scan the first column, see the monotonically increasing time, then can directly interpret the numbers in the second column. In the sentence, you have to filter out a lot of chaff before you can understand (or confirm) the basic pattern in the independent variable. They also mixed up the order of the items in the sentence, making for more 'chaff' obscuring analysis It's not about 'familiarity', but the ease of pulling related information - if the sentence was ordered but the table unordered, then depending on the data, the sentence could be easier to interpret, for example.

The second table is unconventional - it is ordered by the independent variable, but it leads with the dependent variable. If we had the convention of putting the independent variable on the right, this table would be perfectly familiar and readable. The rationale isn't "the important information is the temperature", as the article says, but that the table is ordered by the independent variable - we need to know what it is and how it behaves, then we can more easily the relation of the independent variable against it.

My biggest benefit is working with multiple artboards. As we all know, design now starts with going mobile first. Right from the start there is a mobile view, tablet view, and desktop view.

Other pros

+ Text Styles (Save a font style for h1,h2,h3,p. Why hasn't anybody else done this?)

+ Better color picker because it magnifies to the pixel. Much easier/faster to find colors on text.

+ There's like 10 colors on your active palette. Photoshop is 2.

+ Faster to export images.

+ Duplicate/Copy anything faster than Photoshop.

+ Opens up way faster than Photoshop. Similar to opening a text editor.

+ It's $49 vs $50/month for Adobe CC.
Wearables versus there-ables by naveen
Didn't watch but,

1. Super-correlation is entanglement.

2. Tr (ρ log_2 ρ ) = Σ_k of λ_k log2 λ_k where λ_k is the k-th eigenvalue of ρ. Sometimes the log2 is instead ln.

3. Density matrix indicates degree of entanglement. You can measure L or R polarized light but you have an entanglement of the two. Mind you that detecting a bell state without loopholes has, to my knowledge, never been done. A systems density matrix for a system can be measured statistically (Quantum tomography?).
>I used to be a fan of the Many Worlds interpretation, but after seeing this, I'm now a big fan of the Quantum Information Theory explanation.

I know that both MWI and QIT interpret entanglement differently but I am not sure if I understand why one precludes the other (Your g+ post didn't help me much). Can you please point out exactly where the conflict lies, as they still seem compatible to me (perhaps with minor adjustments)?
The biggest problem I see with such effects is that they make the image artificially noisy and hard to see - it gets harder to understand the visuals and get a feel for how the 3D space is structured. It definitely looks pretty in a still image, but most games feature nearly constant movement and a visual designer needs to take into consideration the strain such filters put on one's eyes.
Ask HN:  Game where the participants change the rules?
On HN I once saw some discussion about a game meant to be played via bulletin board or email. Each turn, a participant may change a rule. The game ends when a player wins, but players can also change those win conditions.

Surprisingly, some googling doesn't turn up very much, and I figured an HN post would be more valuable anyway.

It's amusing to think about trying to get a game going via this HN post. Each comment subtree would become its own strange little game. It'd never work; chaos would ensue. Amusing chaos. Probably best not to do that though.

Anyway, does anyone remember this game? What was it called?
It puzzles me why Firefox can't support Antialias fonts and the same video types supported by Chrome and Safari. Will find a fix. Thanks for letting me know.
I have a question. I just went to a source of physical (quantum) randomness http://www.randomnumbers.info/ and I'm giving you a random number between 0 and 10,000 which I've just generated there. Here it goes: 6296.

Ok. Now that light cone had finally reached you. And you (neurons in your brain to be precise) are thoughtfully entangled with that random event (outcome), now in your past.

Now imagine the following. A few days passes. And you forget that number. A few years passes. Connections between the neurons which were storing this information are now gone. Molecules and atoms which were part of these neurons are gone from your body. There are no entanglements any more which link you to that event. Is that event in your future now? Again?

Similarly, I have a sticky note attached to my monitor which states that anyone who runs their code on my machine (via Javascript, for instance) in exchange for any benefit (tracking data or ad impressions, for instance) must submit any claims against me to my chosen artbitrator (hi, mom!). I also plan on stealing a lot of cereal.

When I am effectively the server's server via running code on my machine, it seems like I have exactly the same right to declare unilateral terms-and-conditions for the use of my resources.

Well yeah obviously, I was talking about the second-order effect of the parenting. Like a control signal being modulated onto the main signal (with the main signal being a child's endogenous drives, interests and character), or one-dimensional Perlin noise, the parenting needs to follow the primary amplitude.
The courts have established that certain contracts are simply invalid by their nature, and many instances of "signing away your right to sue" fall in this category. The real reason that companies have you do this is to reduce the chance that you'll sue, not reduce the effectiveness of such a lawsuit.

Well, not really. During the time where you're building up those 50 'lost hours', your body is performing worse. What you owe in sleep you'll (immediately) pay for in reduced quality of wakefulness: lower mental acuity, worse immune system, poorer physical performance, slower recuperation, etc.

> 1) What does it mean that entangled particles are supercorrelated? How can S(A|B) = 2 or -1?

The density matrix does not have the same properties of a joint probability distribution, so quantum entropy doesn't really have the same properties of classical entropy. [1]

> 2) The formula for Von Neumann entropy is S = -Tr(p log(p)), where p is the density matrix. How do you take a log of a matrix?

The log of a matrix is defined as the inverse of the matrix exponential. The matrix exponential can be defined as the usual power series, only using matrices rather than scalars.

What one usually does is: diagonalize the matrix (if possible), take the log of the eigenvalues and rotate again. Obviously taking the log of a matrix is a little trickier than the exponential because if you have negative or complex-valued eigenvalues you have to be a bit more careful.
