[i work at meteor]

After we announced 0.9.2 and hot code push for mobile apps, many of our users wanted to be sure it was kosher. It's easy to get confused about this because the App Store review guidelines suggest that downloading code isn't okay. And many Meteor developers don't have a deep background in the iOS ecosystem. The cool part about 0.9.2 is you can build mobile apps with just your basic Meteor/JS/HTML5 knowledge.

Apple's formal developer agreement is both controlling and clarifying, and since it's a bit harder to find we thought it would be good to point Meteor developers at the key part.
64% is the savings when comparing the cost of running the instances before and after scheduling. This directly correlates to the hours we dictated the machine to run (instances "on" about 36% of the time). This is also a very rudimentary example without dynamic scaling.

So getting down to comparative costs, I wrote the script in about 90 mins while watching a TV program. Coming up with the numbers to compare before and after was 10 minutes at most. While neither of these incurred no loss of regular schedule time during the day (done at home on my time), you could account my hours at home by my some hourly rate. Even at very generous consulting rates, the ROI for these 100 minutes was easily realized in the first week that the script was in place.

We were able to save $183 per week with this solution and that only touched 6 of our instances. We still have 1-2 orders of magnitude of instances to apply this to. This was identified as a quick and easy change and had the ROI been something months ahead, we would've addressed the issue in myriad other ways. These machines were already provably not being used during specific hours of the day, so uptime wasn't so much surrendered as the instances are set to be running when needed stopped when unused.
It is not my tool (in the sense that I didn't make it). Also, consider submitting your picture to the forum. Wrote about in another post below.

What is the probability of one person wanting to do damage? Square that.

Now consider that even if two people wanted to do damage, each might not know and trust the other to allow them.
Mm absolutely - hence why 'removal of empathy' to result in the kind of aforementioned controlled psychopath sounds like it might result in the controlled individual, might it not?

You're absolutely on-point about regular psychopaths of course (as you know better than I).
I'm not sure what you're disagreeing with, then. The article specifically points out that playing the "perk war" is a bad idea, and people who are swayed by things like laundry service are likely not the people you want.
Thanks for the USPS tip, didn't know about that.
You aren't the first with that idea, though hopefully you have enough knowledge to pull it off.

It'd probably be more simple to just make one type for each class of device:

That should be #!/usr/bin/env bash, particularly for BSD which does not install bash in /bin. Nothing new about absolute executable paths being non-portable, #!/bin/bash is as bad as #!/usr/bin/python.
Skylab construction cost: 10 billion in modern dollars

ISS construction cost: 150 billion

ISS science projects keep on getting cancelled for budget reasons. I think spending $150,000,000,000.00 building it has something to do with that.
I have an upsell for you to consider. However, a small word of caution regarding artists - they are like herding cats and as the legendary Paul Graham discovered, quite hard to base a start up around! However...

The upsell is for the artist's market. They need to get their pride and joy off to galleries and shows. So even if they are driving the stuff to the gallery themselves, it still needs to be packed and made transportable.

The solution - 'art bags'. These are tailored to the frame with a few inches to spare and are made of that bubble-wrap that has mylar film backing in it - heat welded together, rip-proof and good for shifting framed artwork around without it getting damaged. A simple flap - add velcro if you must - closes the bag. Prominent on the front is an enclosure to add a picture of the picture with the expected fragile notice, artist's name, name of the piece, phone number etc.

Obviously such bags can be used for shipping the frames so you can sell on your packaging :-)

There is an un-developed market for this in the UK, as in a cottage industry. As a standalone business it is a hard sell, however, as part of a framing business it could work out quite nicely. Plus the start up costs for the materials and welding device are not great. Trade building supplies places sell the mylar film bubble wrap stuff so it is not hard to get.
Would this reduce the storage lifespan of the disc? Would this technique make it physically more brittle, if the current form factor is used?
People don't really dislike Macports, they just like shiny new things on github.
I got triptychs on the roadmap - huge fan of how those look!
I'm amazed this got upvoted to the front page. Is this really news for so many of you, or are we being trolled?
I do somewhat believe this, but this ignores the fact that people will trade money for time and convenience. Things like not having to worry about doing laundry, or cook, or pick a place to eat, etc. are often things people will "pay for" via a slightly lower salary.
> Why would you want that? The magnet links alone are rather useless. The whole site can be crawled within 2-3 days easily.

But the entire site archive is already available as a torrent indexed on TPB - why bother crawling? That's what I'm referring to - search "pirate bay archive" on TPB and you'll find it.

The magnet links are not useless, because they are able to query the rest of the metadata from a tracker and/or DHT.

I'm thinking about this from the perspective of 'minimal amount of information needed in order to reproduce TPB', not 'how much information does TPB index (which is obviously much larger).

(Remember that TPB no longer even operates its own tracker, so if TPB itself were taken offline, the magnet links would still work fine).
Do we really need to repost this every 2 months? The first proof of concept for this kind of attack has been demonstrated 7+ years ago at the CCC. It pops up every year and every time people act like this is news.

>The point of a good hash function is to have no such structure.

Our hash functions are not perfect with respect to this.
While the title isn't necessarily false, it's misleading link bait because people click on it thinking that Apple is now allowing us to push out Swift/Objective-C updates in-app. It's more feasible than ever that this could happen now since they've added the ability to include frameworks inside of your apps where previously you couldn't.

The link is referring to using HTML/JS/CSS to update apps, which has been possible since the UIWebView in 2.0 - literally for years and years. You download those files and view them in a web view – technically it's running javascript "hot code" but this isn't news, it's been around since we could develop apps for iOS. A better title might be "Apple allows you to download and view HTML in a web browser inside of your app" but that wouldn't generate many clicks.
We quarantined it because it is connected directly to Internexa and we were unhappy with their accidental route leak.

You're describing MS Access.
nice. Everybody of course knows (at least deep inside oneself if the one is too obtuse to acknowledge it publicly) that, starting from the ancient times, all the encrypted communication stuff around has always been backdoored, yet seeing actual confirmation is always assuring :

"Others contained clues to a secret trips that Friedman had made to Switzerland, where he helped the agency gain backdoor access into encryption systems that a Swiss company was selling to foreign countries."
This is the kind of advice you give to people you want to compete against.
Facebook Linux Mirrors
Potential NFL and Facebook partnership
I'm puzzled as to why there's so much negativity toward the idea of having a social life that involves your co-workers. There was a line in the article that really rang a bell with me, about how you spend a large amount of your waking life at work, so why not try to work with people you'd like to hang out with otherwise.

I have very strong social circles both in and out of my company, and those circles even mix. I've been markedly less happy working at companies where I wouldn't consider going out for a beer with the people I work with.

Now, it's unclear if Thiel is actually advocating centering your entire social life around your company. If that's the case, I certainly disagree with that premise, but I would find it intolerable working just with people who I only cared to see during work hours.
Huh. I had no idea. I've been using MacPorts for what must be a decade, or close to it. Tried Fink a few times, never had any luck -- but never had a reason to find anything new (brew). I guess the Ports versions of everything I use are "good enough". If it ain't broke, and all that.
Separate rooms with separate access control for redundant systems. Preferably made so fire from one room does not spread to the next.
> Also, I can make backups of my blu-rays all day.

I'm not disputing that. It's that backing up files isn't a manually intensive process, whereas backing up blu-rays is. In fact, it might literally take you all day to do so. Backing up files can take 0 seconds of the day, and you don't even need to think about it. That's why I like to buy digital: it saves time.
How Visa Chief Is Fighting Back as Transactions Go Digital
Since the newer versions of Access use SQL Server Express as a backend, I would expect them to be significantly more reliable and performant than MongoDB.
I prefer Homebrew over Macports, because the Homebrew default is to use the stuff your system already has. Macports always wants to pull in (newer versions) a bunch of stuff that's already in OSX.

There's benefits to both approaches. However, I really only need a few extras on my OSX laptop, and I don't really want to end up compiling dozens of extra stuff just to get the latest version. Sometimes I want to force that new version, but only if there's specific functionality I'm after. Others really want to get the latest and greatest of everything constantly...
It takes some time to find some exercise that works for you. I hated the gym, running bored me, I didn't really fit in with the fightsport crowd in my city (all started classes were filled young kids, you might have better luck in a bigger city!) but swimming has been awesome so far. I used to stay in shape by cycling to work everyday but over the years I have become fatter, slower, less attractive, depressed and far less sharp.

I swim almost an hour everyday and during the weekends I sometimes go for 3-4 hours and it has done wonders for my depression, it also enhances your mental clarity and swimming is a great way to work out those hard recursion or architectural problems.

I used to deal with overwhelming negative emotions in less constructive ways, some days I still swim to "destroy", endorphins also work great for emotional pain so after that I usually feel a lot better.

I hear great things about climbing from other programmers. If you're depressed find something that you enjoy as a exercise, once you get the basics down it becomes a "flow" not much different from programming :)

I also take some St John's Wort, some vitamin D and I replaced most breakfasts with Soylent. So far it has done wonders in fighting my depression.
Why Continuous Integration Doesn’t Work
Ask HN: What do you code when you're learning a new language?
Hello there!

preface: CS student here, not working right now.

As many of you, I learn by doing.

But I am in a strange situation: I would like to learn a new language, but I don't have any itches to scratch, I don't need a particularly non-existant piece of software.

So I was wondering: have you ever felt like this ?

What would you code when you want to learn a language but you don't have something to code?

It just came to my mind that maybe I should just prepare a set of algorithms and just rewrite them every time i have to learn a new language. But this doesn't feel like the ``right'' solution.

HN, what's your advice ?
Actually, this doesn't follow at all (although it is what the article author claims). The exact inverse is true.

In the extreme case, where we require no zeros, the problem is trivial (just hash any old data), and any good SAT solver will finish fairly quickly (perhaps with a little guidance). If we require all zeros, we are effectively asking the solver to break SHA2, which no SAT solver is going to do well at at present, or the forseeable future.

While assigning variables does decrease the worst-case complexity, no number of zeroes can be brute forced by exhaustive search before the heat death of the universe, and assigning zeroes makes finding solutions harder in a search problem which is still massive.

I don't know that it's plainly better than a QR code, but your point is presumably well taken that if a broad area were saturated in ID signals that would be better than a single fixed QR code, once the user knows that the physical web is supported. I was thinking mainly of this in the context in which it was presented, which is being embedded in discrete objects like vending machines or the like, in which case the search space for a QR code is fairly small, and advertising that the physical web is supported could be replaced by existing technology.

I also don't see that it's "plainly better" to click on it through a phone. It depends on the different interfaces. How much do each of these things cost? If we're allowed to spend infinite money on any minor improvement, why not give everyone HUDs with high resolution cameras that can scan any QR code within line of sight? How much battery life are these scans taking? How much complexity do they add to the phone UI? What will the security issues be? I'm just not sold on the big benefits here.
> One question, it specifically mentions using the WebKit framework, does that mean that this is not allowed under the old UIWebView class?

This is nothing new. We have been using UIWebView to download JS code in our App Store apps since iOS 3. You can use UIWebView or WKWebView. I don't understand why this is on the front page of HN except that someone over at Meteor is doing a good job at drawing attention to their framework.

edit: I do understand that App Store rules can be confusing and Meteor may need to have this PSA to ensure their developers feel comfortable using their framework. But ultimately it's still nothing new, not news, and probably doesn't belong the HN front page – I'm sure I wasn't the only one who clicked the link thinking it was for native apps only to be disappointed.
Interesting points. This is the source for the quotes in the article you linked to: http://archives.republicans.transportation.house.gov/Media/f...

Germany Considers Banning Work Email After 6PM
Right....but your user shell has nothing to do with shellshock. Shellshock involves things like Apache invoking system calls that need a shell, and those system calls don't care what your user shell is. They care what /bin/sh and /bin/bash are (or wherever your system shells live, it's /bin for OSX).

This guide is claiming that updating your login shell to bash via Homebrew will mitigate shellshock, which is flat-out wrong, and dangerous to boot.
It is true in an absolute, mathematical sense that the search space gets smaller when you fix a variable to a particular value.

However, by fixing a variable (and effectively removing it), you are also removing potential solutions from that search space.

In a sense, you could view the difficulty of a SAT problem as the fraction of valid solutions in the whole search space. By fixing a variable, you are decreasing both the number of valid solutions and the size of the total search space. But the fraction could end up being either greater or smaller, depending on the variable and the value you set it to.

> It helps you answer the only question that matters: is your product something people want?

I've probably read that sentence at least 1000 times in a number of different books and articles. Having gone through a lean startup accelerator a few years ago when they were en vogue we focused on this aspect more than anything else.

The thing I never hear is how people actually figured that out. Cold calling, cold emailing, going to meetups, getting intros, pitching ideas and gathering feedback is never discussed. I want to hear _how_ you found a product market fit. It's obvious that you need to do this.

As an example. A startup that I co-founded my sophomore year in college was accepted into a school run summer business accelerator. They emphasized talking with customers/users more than anything else. The problem was we didn't really know any of our potential customers or users (grade school teachers/public schools). So we had to essentially cold call schools, find teachers/admins emails online, and fish around our personal network for intros. To say it didn't go well is an understatement. Our success rate, of even a phone call, was nearly 1% (roughly one answer per 100 or so emails/calls). We eventually locked down a core group of users simply by contacting so many people. Aside from other bureaucratic factors in the public schooling system we failed simply because we couldn't establish a growing user base.

So, if anyone wants to tell their story with nitty gitty details of not only how they found and retained their users but how they found what they wanted would be greatly appreciated.

I don't want to flag stories like this when they don't actually violate the terms of use. But IMHO, there should be some way for users to express the popular "Why is this on Hacker News?" sentiment without cluttering up the comment thread.

Otherwise, we'll just end up with upvoting cabals, and I'd argue that this story is likely to be a prime example of such.

Case studies in education as applied to non-atypical brains are essentially worthless. You'd think that someone with a newfound scientific disposition might realize that you probably shouldn't make sweeping prescriptions based on personal anecdotes (though honestly, based on the quality of the educational literature I've seen, it's not uncommon even for professional education researchers).

>>"If psychopaths are effectively those people who lack empathy, then who shall we become if we throw it to the wayside?"

A few comments down a good note is made that "[Psychopaths] are more 'broken' than 'empathy selectively turned off.'"

>>"then who shall we become if we throw it to the wayside?"

This question does not end up as rhetorical as you intended if you refine your definition. Maybe now you can put forth some attempt to answer it?

I also have issue with you claiming to find value in utilitarianism with respect towards moral dilemmas but then choosing to simply not believe in an answer it imparts. My impression of your comment is that you are basing your value of this consideration on simply not liking the answer. If this is an unfair judgement please correct me, your original does not have much to go off in the way of developing a full picture of your opinions and leaving your comments as bare as you do leaves them open to interpreting flaws you may have already considered before posting.
PSA: Talk to a doctor about serotonin syndrome before trying St. John Wort if you take a SSRI.
Makes sense. Most of my art is $20-40 prints bought to support artists at conventions and a simple pine frame would do the trick. Eventually I'll just cut my own.

I'm glad to see OP is targeting the higher end market with the possibility of expanding to the low-end later. It's not what I'm after, but it clearly has value and at least he's not trying to do it all.
The article contains original reporting with newly sourced details not available elsewhere. As a result, as of this moment it's the most detailed article available. It's the best you're going to get, like it or leave it.
I would disagree. I know a lot of "normal people," and most use their browser to google or search using their preferred engine or a particular website, as well as load links from emails, or visit websites on the go.

Personally, I'm not sure that using a particular company or product's app really saves me any time. Half the time, the app takes forever to load or is so non-properly story-boarded, that I resort to google anyway. Maybe I'm the outlier.
