> It can almost sound simple but that's really really hard.

It really _is_ hard. No way is it easy

> I say that as someone who has spent the last couple years talking with my friends about whether they would be interested in being co-founders for startup ideas and searching for problems in my own experience that would make for scalable ideas.

That is the biggest problem in getting it going. You have to be able to convince others to share your vision. But isn't it easier to do with long-time friends than that guy you met last summer? When you know someone for long enough, you will have the confidence that you'll stick together through the friendly breezes and the wild storms

> Are good hackers

That is a requirement for a good reason. The founders are the only guys initially who give a sh*t about the product. Say a customer makes a support call, being able to quickly respond and fix the bug can mean life or death. You need at least one hacker who can do this. Better if every founder is one.

> I go out and talk to companies and I don't see much of what YC explicitly asks for.

YC in no way has the magic portion. They just have a set of things they believe are positive indicators, which are mostly right, but not fulfulling one/all of these no way means you can't build a successful startup

> It's not far fetched to imagine they interview nearly 100% of the teams that fit the profile above.

That's not surprising, is it? If 70% of the slots were filled with applicants that fulfilled 100% criteria, then they might loosen some of the criteria (like single founder teams, idea stage etc), but with the momentum that YC's gotten, I bet 100% of the slots get filled with startups that fulfill 100% of their criteria (and more, those corner cases). So obviously, they'll stick to their criteria (which has been working for them)
Yep. The article said there is a similar program in Israel.

“They say they’re drinking more coffee than before, about 20 percent more,” says Rotem (who, by the way, drinks four to six cups on a bad day). “Our users save around 30 percent on coffee.”
Ask HN: how do I promote on Hacker News?
So I've made https://pintask.me/. Since it's a hackable task tracker, Hacker News is THE place to promote it. But how do I do that without pissing everybody off? :)
Agreed; I would also say that you should run from Bash not when you need anything more than a simple array, but when you need any kind of array, period.

The advice on functions also gives me pause because that helps you write longer Bash scripts...not a good idea. Functions are of limited use because they can't really return values (just an exit status.) If a function has to return something, it generally prints it to stdout...which requires use of command substitution to get the result...nasty.

Shells are good for interactive use and for starting other programs, but it's a lot easier to take a full-featured language and make it work like a shell than it is to take a shell and make it behave like a full-featured language.

I'd take this blog post, add considerably to the "when you shouldn't use Bash" list, and put that at the top of the blog post, and then say "but if you absolutely must use Bash for something that is not trivial, here are some things that can make the process manageably nasty instead of truly horrid."
Espresso as a Service? I like it.
Sure, use whatever other registrar/host you want, but it quite evidently doesn't exactly help people who aren't using godaddy but still have to deal with abuse related to people who are.
Confessions of a Full Stack DevOp
Publicly discussing the flaws of a technical book actually helps a lot of people. I don't understand how it could possibly be better to have kept these comments private. By making them public, there are people who would have taken this bad advice who now know that it's bad advice. That makes us all more secure.

I really truly cannot understand the critique of an "experts only" attitude when it comes to technical books that make important recommendations for building critical systems. By all means, non-experts should experiment and build and learn. But non-experts definitely should not be giving out large quantities of advice in an authoritative tone.
If you're writing a book on a serious topic like security, you are presenting yourself as an expert and need to be able to stand up to the criticism. It goes with the territory.
I think people involved with it over the long term have always said that it's a risky experiment that might fail. Bitcoin resembles a sandcastle far more than a honey badger, that's for sure.

"Honesty" is defined to mean "following the rules". The first seen rule is a part of that set. BitUndo isn't attempting to fork the chain today, but they certainly could - it's a simple extension of their model. Double spending for a fee doesn't really care whether a tx is unconfirmed or not, it simply alters the price charged.
Not if you only allow the phone to mine when you are not using it, when it is charging, connected to WiFi, and when the temperature sensor is being monitored.
The user could also only give permission for mining in short periods of time.
Yep!

And thanks to oh-my-zsh (https://github.com/robbyrussell/oh-my-zsh) it really requires very little fiddling, maybe 10 minutes worth.
Excellent, bash the good parts. More than 15 minutes though.

Googling bashlint, shlint turns up some discussion (bash -n, ksh -n, zsh -n, some github projects), but I doubt they cover this article's specifics - though most (all?) of it could be automatically checked. I think some could be automatically added (e.g. set -o nounset) - perhaps a bash-subset (or coffeescript-style language) possible...
Morals?

That's a really good point though. I wonder how many people will get a coffee for a friend waiting outside on their subscription or even split a subscription.
Nice job, will be checking in periodically.

Aside: when will LivingSocial be there? ;)
> he instead chose to lambast kyle publicly, which doesn't really help anybody

It helps people who might have read the book and learned to do things the wrong way.

We can model this as "Kyle has disseminated harmful material, and tptacek is trying to contain the damage". Kyle's feelings, intentions, and hard work aren't irrelevant; but they're not what we should be focusing on.
The last paragraph of the article says, "For whatever it’s worth, fiendish subscribers must adhere to at least one limitation: They must wait 30 minutes before ordering another coffee."
Looking at the code used in the OP, ggmaps does not require a dependy on a different program (and it also used a .dll, which may make it difficult to use cross-platform as well.). ggmaps also used ggplot2 syntax, making it easy for style customization which I don't see in the original code.

Although, using a shapefile adds another R package dependency, but not much more LOC. Alternatively, use the maps package, which also contains data for reconstructing popular maps like the world map used.
I'm not sure what good this would do. Wouldn't the spammer just include the ones that had not opted in (while claiming otherwise)? It'd be hard to prove them wrong.
I'm a dev, but got my degree in optical engineering not that long ago.

The reason this is not news is that good microscopes cost money. Saying "hey, I've achieved 2100x magnication!" is pretty meaningless. Anyone who's ever used a nice camera can instantly realize the difference in the photos you get with a $500 Canon lens compared to that disposable camera you bought for $5.

The pictures they've supplied are wonderfully blurry. Three cheers for poor light sources, spherical aberration and diffraction blur. If you're doing slides with results of great import, such as various health tests, you want an accurate image. We don't get to see any shots of optical calibration targets here, which would demonstrate just how poor the optics are. As a rule of thumb, anything over 1000x is usually poor and 1500x is considered the practical limit of optical microscopy (without some really expensive tricks like conjugate points and fluorescence which gets you a $100K+ kit).

So yeah for cheap microscopes!, but I had a $5 one as a kid. Nothing new here. Plus, training people to properly prepare the slides and interpret the images correctly is a far larger problem. I've watch Harvard and other labs haul away truck loads of old equipment to the dumps. Let's send that to anyone in the 3rd world that wants it, but not waste too much time doing what's already been done.
Hmm. I'd like to see a demo of the first claim.

The 2nd claim is nice, I suppose, but FA also has 369 glyphs compared to 218 in OI, so the per-glyph file size advantage isn't actually that dramatic.
> Weight matters? I have never heard "I wish my phone was lighter" from anyone, anywhere.

Your anecdotal evidence is about as valid as mine, and I can guarantee you that weight matters. Tactile feel matters. Looks, of course matter.

In all these cases, a modular device fares poorly compared to an integrated one. This is a handheld device - can you not imagine the amount of dirt and grime that would cake up between the module gaps if you don't have a case on the device? And if you do have a case, now you have to uncase to switch around the modules.

The era of modularity is past, or not yet ready to come back.
"The two settings also have shorthands (“-u” and “-e”) but the longer versions are more readable."
The opt-in argument is useless since there is no way to verify that the user subscribed in the first place, giving them the address or not. All you do is providing value to the spammer since they have now verified that the email is indeed real and read by a person. When reporting abuse you can already forge any email out of nothing, and you cannot prove that the email was forged unless they have a trace of the email being sent by their server (logs), and if they have that trace they can see easily see a pattern of mass distribution and start an investigation by contacting the other recipients on that list, or just wait for more reports to come in. Guess it's been a while since I worked at an ISP, but I have never heard of a spam abuse investigation strategy that involves forwarding the address to the suspected spammer.
Anyone can apply. :)

I'd guess 12V is for lower-power devices, where (slightly) cheaper 16V-rated (the next step below 25V) capacitors can be used. The other parts (switcher ICs and MOSFETs) are usually rated for much higher, and the system would be fine with a 20V input if it weren't for the 16V caps.

E.g. the EEE 1000HE uses a 12V adapter, and it has 16V caps in its power circuit. Probably the same for the Surface/Pixel.
Yes, there is that limit –– and a good one. You could get around it maybe if you were with some friends doing a klatsch with staggered drinking rates and drink start times, but then you'd just look really cheap.
You wouldn't in common cases because as an individual you are not required to care.

However if you are an owner of a database containing personal information (where database means collection, not a particular technology), then rules are different. You then are required to collect only what you need for purposes granted by their owners and have to take care of not disseminating it without approval to others.

Google wasn't allowed to collect Street View data until they could conform to our privacy laws which mostly meant not making photographed people easily identifiable. This requirement is in no way specific to Slovenia (e.g. I think Germany has the same one) and Google complied which is why you can use street view in Slovenia now.

I would not describe our computer-related laws crazy. They are lacking as laws everywhere are and certainly sometimes in uniquely our way. However it is often the enforcement (or lack of) that is the problem, not laws themselves.
Regarding the shoes: making it clear to you that he did not mean any harm is a way of apologizing and defusing a potentially explosive situation. I hesitate to read too much into it.

Regarding tptacek, I suspect that if he had sent this to the author, or posted it as a formal review, I suspect he would have toned down the description of his reactions. I'm not sure where this review came from, but my impression is that he did not think of it as a published review that the author would see. Certainly doing such would be advisable, as people are more receptive to criticism that way.

Perhaps I am wrong regarding how tptacek would have responded had he known the review would be, essentially, published. But I know I phrase things differently in such situations.
Awesome! Can't wait!

Security isn't a binary yes/no thing and double-spending-for-a-fee does not require unconfirmed transactions. Confirmed txns can be replaced too, it just costs more.
After I finished reading this review, I came to check out the HN comments knowing that the tone would be the subject of the top comments.

When did this community become more concerned with tone than correctness? The top of this thread is filled with people saying that the tone is bad, it's unproductive, it's unnecessary, etc. Yet nobody seems concerned about the published book filled with bad information that a lot of people are going to "learn" from. What gives?
Hopefully this is better than WP7(.5), which I personally could not stand and ended up getting an android phone.

My #1 major gripe is that it is a phone second. I could write games for it in C# with XNA, but I couldn't set a custom notification sound. It's dumb priorities like that which made me abandon it.
And note it was closed by blackberry after they purchased qnx.
Ask HN: What happened to "Save"?

Estimote announces RealityHack Challenge for home automation apps
When you are writing about a difficult subject, you should invite reviews from experts to vet your work.
Also, in graphs on random data, using strength on the strings between nodes to separate them is an automatic way to create a layout where all nodes can be seen.
Oh, that's even worse.
> I've never heard of any provider making someone turn over their mailing lists. Do you have any further information about when this has occurred?

---

I didn't mean to imply that was what happened. I said that they'd have to if it's to be checked.

My thoughts were that you're either going to have to trust the accused spammer - in which case you can turn over the SHA of the complaining email address, and the provider can compare it to the SHA hashes of their own. Or... they're going to have to turn the list (again, preferably with the entries hashed) over to you - and then, I suppose, you'll have to trust that they're giving you a truthful list.

But, either way, I don't see how the mere act of hashing the list is going to significantly alter the problems of nuisance complaints or of dealing with large lists. Hashing is a very cheap thing to do after all.
Interesting observations on the flux between fixed and modular here. PCs today are still modular devices with varying degrees of specialization. Macs have less modularity. What they both have in common are peripherals.

Until now, smart phones/tablets have had little in the way of peripherals. Some headsets, keyboards, memory cards, etc., but people seem to be clamoring for certain peripherals above all others. They seem less concerned about CPU types, just like the in Mac and PC world. Key peripherals seem to be camera and some kind of "geekport"/internet of things.

I don't see a need to modularize every part of the phone a la PCs, but to expand the peripherals would help. It might be as simple as adding extra USB ports.
Watches actually listen to WWVB, not WWV. (WWV is on HF, WWVB is on LF.)

On a good propagation day, you can probably hear WWV around the world. If it wasn't for other countries broadcasting their time stations on the same frequency, that is.

Ultimately, LF time synchronization is a good idea. It doesn't depend on additional ionospheric information to get an accurate time transfer, since signals do not travel through the ionosphere. HF signals take different routes at different times of day, and GPS time transfer requires an accurate site survey and accurate ionospheric delay constants.
And if Java isn't trendy^W exciting enough for you, Scala offers many of the same benefits, in particular the use of the JVM and access to the Java ecosystem, but with many more options for functional programming, "expressive" constructs like DSLs, actor-based architecture, etc.

You didn't wonder why the poster mentioned Slovenia specifically? It's a bit of an odd choice for an example. It's like the poster knew something personally identifiable about you.
Significant savings for some.

If you had a 2 cups a day coffee habit, this works out to about $.73 a cup or $1.45 a day. Pretty good deal if you like coffee shop coffee.

Assuming you'll otherwise spend $3 per cup you'll save about $1657 a year. $2190 vs $532.90.

And it is also very niche. The custom PC market has been, and will continue to be a "healthy" market, but it is by no means a growing market. The difference between a custom built PC, and a modular designed phone, is that for the most part, a static device, that is, it doesn't go anywhere, versus a phone, which will be abused just by the nature of the fact that it is a mobile phone (I mean the presentation is proof of this, the phone broke the day before).

Now am I saying that there is no market for this, absolutely not, but this in no way will become the standard for a variety of reasons, but the biggest one to me, is time. I used to build all my PC's, taking the time to compare parts, read reviews, check out overclockability, and look for deals and get the best bang for my buck, but as I have gotten older, I just want a machine that works, my disdain for everything Apple, has completely turned around, I absolutely love my Macs now, not because I think Apple and Steve are gods gift to computing, but because they work, they maintain resale value, and compared to PC hardware, they are superior.
Sleep Hacking: How I went from 11 hours of sleep to 6 hours of sleep
You're right, I should've narrowed the scope to client-server or perhaps "the web" (although the exact lines are blurry).
You've basically done all you can do... submit it. Now wait a few months, make some improvements, and submit it again to show your improvements. Anything more often than that would be considered spam.

You could also put more information in your profile and then just participate enough that people want to click your profile to see who you are and what you do. This is probably the best long-term plan. If someone on HN wants to hire a security research firm, who do you think they are going to go to first? (If you don't know the answer, that's good evidence you need to participate more!)

Lots of products of HNers have become popular on HN because of the creator's participation. DuckDuckGo is another good example.

I'd say that a prevalence of rich kids is alarming, and not from an equality perspective or anything. It's alarming because an advanced and specialized economy like ours is at its most efficient when people are doing the jobs they're best suited for. If I'm well-suited to be a DBA and I'm instead doing something I'm much less well-suited for (like sales) then it's a societal net-loss[1]. Unless we assume there's a reason that the people who are best-suited or at least well-suited to be doctors are disproportionately rich, then we're probably winding up with poor/middle-class folks who'd make excellent doctors doing some other job they're less good at.

[1] This is not and should not be read as an argument that DBAs > sales or anything to that effect.
The word "user" seems strangely appropriate.
Cool idea, but it seems to target a pretty narrow demographic:

- wealthy enough to live in NYC and buy at least
one cup of coffee every single work day

- cheap enough to want to save a few bucks a month on coffee

- can't be bothered to carry a credit card around every day

- can be bothered to carry a smart phone around every day

- trendy enough to frequent NYC coffee shops

- untrendy enough to be seen using "coupons" in public

- techy enough to consider installing a coffee buying app

- non-techy enough to not have built a crazy $10k
coffee roasting-grinding-brewing setup at home

Fortunately for them, starting in NYC, that still leaves around thirty million potential customers.

It'll be fun watching this play out.

This is absolutely the right direction, but not in the way you think. This shouldn't be branded as a phone -- size and look matter too much. It should be branded the tool of the future, designed for people people in the field: electricians / construction workers / scientists / tinkerers.
