> In the presence of CTCs, quantum mechanics allows one to perform very powerful information-processing tasks, much more than we believe classical or even normal quantum computers could do

That seems like an understatement if I'm understanding it correctly.

Imagine you have a "time machine" and you want to solve some arbitrary computable problem. You try a prospective solution and see if it's correct. If not, you send the next prospective solution back to be tried on the next go around the time loop. Once you arrive at the correct solution, you send that same solution back so that the iteration stops there. Then the loop repeats indefinitely with the correct solution so that the probability of exiting the loop at the correct solution approaches infinity.

It would literally be the end of the world as we know it. P=NP. Forget about quantum cryptography, that would break all public key cryptography, all cryptographic hash functions. It would obsolete algorithmic complexity theory by effectively turning every finite space algorithm into an O(1) algorithm. It would probably bring Strong AI.

But it still couldn't break a one-time pad.

Isis Iraq War: ISIS Claims to Behead American Journalist Steven Sotloff
Say I go back in time. Does it mean I disappear from the time I was in? And I'm in two places at a point in the past (the me from that time and the me from the future)? Now if I want to go back to the time I came from, do I join back at the exact time I left (which means no one would notice my travel), or would I have to travel back to the time I left + the elapsed time I spent in the past? And if I really did return to the exact time I left, does that really mean no one noticed my leave? Because I'm sure when I left time continued and somebody noticed.

> The email protocol is simple and flexible.

Ha, okay. I'm going to include actual emails in "the email protocol", because if you just count the network protocols you're not doing anything useful. Emails are anything but simple. They were born in the early days of the Internet, and no doubt time and the impossibility of predicting the future is responsible for how things turned out — but they are anything but simple.

Email messages are ASCII only. You can put non-ASCII characters into a header however. It looks like this:

Subject: =?UTF-8?B?SMOpbGzDtOKApgo=?=

Writing a parser for this is an unnecessary challenge in this day. (If you ever need to do email, for parsing or outputting, get a library.) Watching a coworker unwilling to take the time to the read the RFC try to write a parser for this… is a very special hell.¹

The body also has to be ASCII, so just about every email client out there has to do:

Content-Transfer-Encoding: base64

And then encode the body in base64, wasting space and network bandwidth. Technically, you can send full 8-bit message bodies, but the sender and receiver have to agree ahead of time. Either GMail doesn't support it, or it just doesn't bother even when the email destinations are all GMail. (Or, it could be because some IMAP client might get the message, and not support it.)

There's also that every message has a text version and an HTML version — hopefully semantically similar — but HTML support in email clients (at least the big ones) is terrible. (see for example http://www.email-standards.org/ ) You'll think support is great on the web after you're done.

I've not covered un-wrapping headers. Or the things people think aren't valid email addresses. (Your average Joe thinks [a-zA-Z0-9]+@<a domain name> matches all valid emails. Oh, and that they're case insensitive too.) Or IMAP. Or encryption. Or even whether email gets encrypted while on the wire from Hotmail to Comcast.

> Slack pretends to be “an email killer”

I'm not sure they're out to kill all emails… just the ones that would be better as a real-time communication.

¹Don't test your library's output email on Gmail, either. Gmail is creepy good at correcting bad input. "It works on Gmail" != it's correct.

I do wish I could send restructured text emails and have the client just render them. In theory, email has everything I need. Clients just need to support it, that's all. I'll admit, that is kinda cool.
It's certainly not trivial to closely stick to a schedule (e.g. 95% of trains within a minute or two of scheduled times), but it's obviously possible for an urban railway to do so, because many do, often with far more aggressive schedules and higher volumes than Caltrain has.

Of course, many American systems are operating at a pretty severe disadvantage, being hamstrung by poor equipment and infrastructure, a lack of funding, understaffing, a hostile political environment, and even pervasive cultural attitudes that dismiss railroads as being something worth investing in. I suppose given all that, it's a wonder they do as well as they do...

But still, I think it's important to never forget: it's absolutely possible to do much better.
I'm going to give you some tough love here. I'm doing it because others have done it for me, and it's been some of the most useful feedback I've gotten. Sugarcoating things does nothing for anyone.

1) Your landing page does not make it at all obvious what Rakable actually does. I already share links privately (via SMS, email, and Facebook, mostly). It's not that efficient, but it's usually about two clicks. I could install plugins to my browser to make it fewer clicks, but I haven't because I just don't care enough.

Your landing page should tell people how Rakable helps them do something they've already been doing, but does it better.

It also needs to be very clear whether the other party must be a Rakable user in order to receive your links. If they must, then that's a dealbreaker. 100% of my friends are reachable via SMS and email, and close to 100% are reachable via Facebook. If Rakable starts out reaching 0% of them, it's not usable. Even if it gets to 90%, it's still not that usable.

2) The "dearth" that you speak of doesn't actually exist[1]. In fact, I'd say there's a glut of services that allow you to privately share links. Many social bookmarking services offer(ed) this feature.

In fact, "social bookmarking startup" became something of a joke a few years ago, much like "photo-sharing app" and "daily deals with a twist" and "Facebook killer". There were just so many pitches and so many indistinguishable startups in those categories that they've become tropes.

Some of the entrants in those areas failed because they were poorly executed, but some of them failed because users just don't want them that badly. Just because a hundred million people want something doesn't mean it's a sustainable business -- they need to want it badly enough to allow you to monetize it. And if you're not seeing a successful [insert startup category here], it's probably because the idea is bad or unworkable, not because no one else has tried to do it.

The question is, what exactly does Rakable do? I'm not going to sign up just to find out. You should tell me on the front page. Does it organize the links I send to others, so they can log in and see all the links I've send them? Or so that I can refer back to them? How is it different from any messaging service?

3) It's often better to start out by piggybacking on existing channels rather than creating your own. Have you considered creating a Gmail plugin or Facebook app that would scour your messages and organize your links by whom you sent them to and when you sent them?

The cost of user acquisition is just massive, so it's better to have some kind of "secret sauce" that makes it easier for you. And when I say cost, I do mean cost. Lots and lots of money.

Here's a seemingly rare example of something that has unambiguously and significantly improved the lives of millions of poor people across the world. What lessons can we learn to try to repeat that success?
After Postgres got replication out of the box I'm pretty sure it's just inertia and the fact that it's installed everywhere keeping mysql usage up. Postgres is so much nicer when dealing with day-to-day things.

Eg disabling connections per database using sql and having built-in query stats (http://www.postgresql.org/docs/9.4/static/pgstatstatements.h...) just made me smile.

They are the one company that has the ability to really push for user privacy, it's a route Google cannot follow - it would hurt their core business (advertising) too much.

On the other hand, Google needs their users to trust them. If they walk away from Google services, Google loses.

If Apple on the other hand, loses an iCloud customer, their lock-in is reduced, but probably the user will continue to use their Apple devices.

In the end, paid services are probably the best for users who want privacy, etc. Losing trust immediately results in a loss of income. But since the user is paying, they don't have to use and link user data for advertisement or sell the data to third parties.

There is also Ecukes[1] which lets you write Cucumber style integration tests for emacs. We use these exclusively when writing the elisp part of clj-refactor[2]. These are so high level, and readable, that they can often double as documentation.

The only real gripe I have with Ecukes is that the diff of the actual and expected output could be better. Turning on whitespace-mode while writing these scenarios have often solved an otherwise inexplicable test failure.

It will be a tough space no doubt. Even Motorola, LG, Sony and others will struggle. But you have an advantage. You can trade on individuality and the tied up emotions that come from hundreds of years of watchmaking, a personal and almost sacred trade. Apple and the others can never offer that. Don't compete with them. Create your own unique value. Emotion and personal connection is still critical with watches..

Agree with the "young entrepreneurs from top schools" bit. Going to a top school doesn't correlate with being a good entrepreneur. It maybe correlates with intelligence and drive, but more closely correlates with privilege and connection.

There's an interesting correlation between immigrants and entrepreneurship (old-school building a profitable business entrepreneurship, not SV-type scaling an unprofitable business entrepreneurship). My take on this (utterly my own opinion) is that immigrants are less likely to get jobs, so more likely to start their own businesses.

So the people who are going to solve these problems are probably not going to be VC's, Ivy leaguers, incubators, or in Silicon Valley. They're probably going to be bootstrapping (nice bonus: if you're used to living on a very low income then bootstrapping is a lot easier). Maybe the problem here then is not the entrepreneurs, but the media and reporting. We only hear about young entrepreneurs building something awesome with technology. Maybe there's an interesting story about poor, underprivileged people dragging themselves out of poverty with technology?

a) It's a useful project for other library authors; of course they want to announce it.

b) I think the part tucked away at the end about a foundation is actually the most important part. Scala's currently owned by one university and also partially by typesafe, and while on the whole they've done a good job there are a lot of stakeholders who aren't really represented there. For a language that so many different organizations are depending on, I think it's time there was something a little more formal and dependable; many other languages have similar foundations.
It's important to not think about certain hypotheticals out loud, so that you can signal what kind of person you are.
Really appreciate your detailed feedback!

I agree, a lot more work has to go into the landing page. I am currently working on it. Regarding the usefulness, I am on almost all social networks, yet when I have to share an interesting link I email or share the links individually on facebook, and I when I have to share the link again at a later point of time, I have to first try to remember where I shared it and then search for it.

I built Rakable to solve my own problem of sharing content. It allows me share, save links with others as well as build a repository of content.

I fully agree that user acquisition is costly, which is why I am taking small steps at a time and validating the product to understand its demand.

Thanks again!
Beaut, thanks for the info.

Does Android really not provide an auto upload of snapped pictures to the cloud? I was under the impression that they did this way before iCloud even came up. First it was to Picasa or some place, then to the google+ place somewhere.

Either way, I don't even remember if the iCloud upload was default or not. When it was introduced I took an interest to find out how to deactivate that in case it was enabled by default. Don't remember if it was. All I know is, it is disabled on my device and it'll stay that way because I really didn't want to use this.
Can someone enlighten me: what is this simulator they speak of? It doesn't seem answered anywhere in the article what it is, whether it's software, let alone how it works. Yet the whole article relies on it. Does it act on real protons? Or are they simulated as well?

And, most important, why do they trust a simulation device built by humans who hardly understand the matter completely, when the device is then used to make assumptions about that same matter? Is it somehow proven this simulator is correct? And how did that happen?

I agree with uptown. Try to look the life in a fresh perspective with the newborn and you will feel like starting a new life. When my second baby was born I felt that I have a lot of things to take care for my family. If your spouse does not work and your saving is approaching zero then you should think for some part time gig and spend the rest of time with family. Try to save something for the rainy day.
To those who commented on the financial or regulatory hurdles in serving these people:

Maybe another way to look at this is: instead of creating a startup to serve veterans or single mothers–why not create a startup that can employ veterans AND single mothers?

One of the biggest problems facing single mothers is the high cost of childcare. In many instances, it makes going to work almost pointless because it eats 50%+ of your paycheck. So, why not a crowdsourcing service (a la mechanical turk/crowdflower) that employs single mothers at home in the United States? (personally I think people would eat that up and even pay a premium for US-based workers)

Veterans could also do crowdsourcing work, on-demand security, and on-demand driving/moving off the top of my head.

Yet another way to tackle this could be to go into an industry that already has the means/access to help these people and partner with them. I'm mainly thinking of education. California's community colleges (there are over 100) cater to these people already. They have night classes and veterans offices. They have programs for in-demand jobs like nursing. Yes, there's the same bureaucratic/regulatory issues since they're a government institution ... but if Starbucks can do a deal with Arizona State, surely a founder who is ambitious enough can get something done.
