I 'hacked' together a FOSCAM IP camera to capture wildlife in my backyard. Was about $70 for the camera. There's a newer IP cam out from them that costs about $150 and has a much higher resolution.

Getting power to the cam was easy as I ran a really long power cord. It is cheaper to run Power Over Ethernet if you have longer distances (just buy an injector and splitter). If I move the cam further into the woods, I will do PoE (although bought the equipment).

If I go any further into the woods, I will use a solar panel, battery, and inverter.

FOSCAM has motion detection software on-board, so it would also work great at bird feeders around your house.

> When using migrations, the schema is written to that file.

You can also run rake db:schema:dump at any time. So it works great with a legacy database. You don't need to run any migrations for this to work.
That's the beauty of this nginx feature. Up until now, the easiest way to add websockets to an existing application was to put them on a separate (weird) port.

But now nginx lets you multiplex those websocket connections over good old port 80 or 443, while still supporting regular HTTP(S) on those ports at the same time.
Where does it imply that?
Amazing way to go kids, but this could also be bit dangerous if the technology lands on wrong hands.
We come up with these problems too and most of them aren't important. And how are these things solutions, when they're always broken? OAuth 1.0, OAuth 2.0, OpenID - all have their issues, none of them is a sensible solution, perhaps the problem they pretend to solve is only a result of other bad designs?

Pinterest is a Social Juggernaut
Ah! I fear Hollywood and TV has corrupted my understanding of Anti-matter. Thanks for clearing that up :)

Aliens could be enticing us to seek new frontiers for scientific knowledge, but unless this comes to us in messages hidden in crop-circles or revealed through abductions, I'm not buying it!
Unpleasant and unnecessary.
The Reason I Just Deleted My Pinterest Account
Ah, that makes sense. I was looking mostly at the poor file, so I haven't considered comments and such.
"Open wirelessly from your iPad when paired with a receipt printer, as included in the Printing package."

It likely doesn't open the register for cash unless there is a receipt to prevent employee fraud.
The design is great. Even though I don't have a brick and mortar store, it kinda makes me want to buy one, inexplicably.

I wonder how many other things you can sell like this, an all-in-one box, that doesn't smell cheap, like a 10-in-1 games CD?

The best thing I can think of right now is 'gardening in a box'. I wonder what 'startup in a box' looks like.
I agree with you completely.

I go as far as putting technologies like social media, smartphones, and immersive never-ending game worlds into the same category as recreational drugs. These things make it far easier to artificially trigger our reward circuits, than to create valuable interactions in the real world.

It is terrifying in the long term as well, because I think if we keep on this road, we will lose all interest in external reality. (there is a great article making the argument that this explains the Fermi paradox, but can't find the link)

Still, part of me wants Glass, because I have terrible memory and forget life events. :-/
Point taken.

I do want to point out I'm not using them to indicate "end of conversion" or "shutup" or anything like that, I'm using them to indicate that is the end of my solution/problem... as in there are no if/buts or maybes.
Yahoo finance is the biggest finance site on the internet. Sure we like to look at Yahoo as the old internet site that consists of former AOL users, but they do have massive traffic . I think it is a bit pretentious say that many people do not own stocks that visit there, it is an older demographic and older people are more likely to own stock.
Lingual: SQL queries as Hadoop/Cascading jobs
I think this is awesome, and have been using it quite a bit during the past few days.

After trying to use it to find a red based color scheme, I found that many of the reds that I wanted to save often fell underneath the scroll bar on the left hand side, which meant that I wasn't able to save their values.
7 Steps to Get Publicity for Your Business
Thanks! Everybody says this in an acquisition, but I honestly could not be more excited to join the Referly team. One of the biggest reasons why is that my day-to-day will, and already has, changed quite a bit. While we remain devoted to maintaining and improving LaunchGram, I'll be doing a good amount of work on the Referly product as well.
Yeah, they're still rolling it out I suppose. Try http://www.yahoo.com/?p=newyahoo (I think that forces you to the new version, or at least did for me)

That's why I prefer to use my local Vim (Emacs with evil-mode) and its remote editing features (Tramp).
The solution is simple: always speak English. This fixes other similar problems.

The other problem with their voice recognition is speaking English with an accent that isn't US or RP.
That pricing is much cheaper than a full $999 price tag and is entitled to $249 upgrades for future, so it seems to be a bargain.
It has ugly syntax and bad standard function names, and some people code ugly things with it.

/sarcasm
Syntax is by far the most superficial difference. If you're going to actually use functional programming, the trick will be learning the paradigm and not worrying about syntax. In fact, from that perspective, I think Haskell syntax actually wins out: it's extremely simple and very well-suited to functional programming. I found things like curried functions and recursion much easier to grasp and use in Haskell than in Scheme when I was learning both simultaneously.

I certainly do not think that syntax is anywhere near why some people find Haskell hard to pick up. Thanks to pattern matching, the syntax is very visual and thanks to having relatively few forms and keywords, it's much simpler than most imperative languages'.

Also, I'm not suggesting necessarily using Haskell exclusively, by any means; I just want more people to consider it at all!
Espresso Framework - Scalable Ruby Web Framework aimed at Speed and Simplicity
Fixed, sorry about that :)
"Open wirelessly from your iPad when paired with a receipt printer, as included in the Printing package."
Seriously, computer language shootout is just harmful. Those benchmarks are bad (but it's unclear whether cross-language comparisons can get much better), implementations are worse. And on top of that it does not include opitmized VMs like PyPy or LuaJIT (in fact, it does not include PyPy because we complained at some point).
There is a product aimed at doing just that: http://filabot.com/ Closing the loop and attaching the output of the Filabot directly to a 3d printer wouldn't be too difficult.

As 2-D Printing Becomes More Accessible, Copyright Questions Arise
I don't think artursapek is arguing that these technologies are bad. There's certainly a time and place for them all, but they shouldn't be a substitute for a social situation. If I invited my friends out to a dinner and everyone brought a book with them and just read the entire time, I'd be just as pissed as if they were on their phone the entire time.

There's' also certainly something fundamentally different about browsing Facebook and Twitter over reading a book. Books are intentional - you've committed to a topic, and there's a finite amount of information to digest. When you're checking social media, you don't know what you're going to get, but it'll probably keep you occupied. You're just consuming mostly trivial information, hoping something interesting happens on your screen. It's like flipping through TV channels to pass the evening. There's nothing inherently wrong with that, but it's probably something best kept in moderation. artursapek's post is about his observations on how people are increasingly consuming this information fast food in excess.
Any news on building apps with F#? These two articles look like a great start, but it would be nice if there was a more official/streamlined way to do it.

I'm still waiting for part 3 if Dave is reading :-)
Well, I'm still not so sure. I've been doing functional programming for 20 years and I thought Haskell syntax was weird.
Plenty of people have no qualms about wearing their Jawbone Bluetooth headsets in public.
Presumably because it needs to work, over and over and over again, and not really break down ever.
Python has real good, battle tested and actively developed libraries for math, scientific computing and analytics. Most of these are written in C and hence give great performance in addition to the flexibility of python. Some great ones are: Numpy/Scipy, LAPACK, Pandas (lots more for machine learning as well). Also, I think the REPL is no match for IPython :). For your specific domain (math and analytics) python could be a great fit. Of course the lack of type systems and no compile step can be scary, but for a startup, which needs to move fast, python gives you the power of quick iteration. Just to round this off, from the zen of python:

"practicality beats purity."
> Eh, I don't know, Twitter bootstrap users don't appear to agree.. I know it's fallen out of favor for DHH

Yeah, that's all I mean. I agree that it hasn't necessarily gone away in the larger sphere. Just that the Rails community has moved to a different default, so LESS gets harder to use.

I personally am glad, though. I find SCSS more powerful. See, for example, the if statements and loops it gives you:

http://sass-lang.com/docs/yardoc/file.SASS_REFERENCE.html#co...

For another example, around the time when Rails made the switch, I started running into serious problems using media queries with LESS, whereas they've always worked great for me in SCSS.
This is fantastic. The POS space has needed massive disruption for decades. Kill the dinosaurs!
Kindles are simply super-books. I own a Kindle, I love my Kindle. There's nothing wrong with Kindles or newspapers. There's also nothing wrong with reading a newspaper or playing with your phone when you're on a subway surrounded by strangers. I do that, everyone has always done that and always will.

There's a huge difference anyway between iPhones and books/newspapers. It's not a good comparison. The only similarity is the posture one holds when consuming them, which is why your photos sort of work for your argument. Reading a book or newspaper takes effort and concentration, whereas flicking through whatever stream on your iPhone takes little to no thought at all. It's active consumption vs. passive consumption.

I believe that to live a healthy life you do need a good balance of production and consumption.

Several of you responding to my post seem to think that I miss a time when everyone used to talk to everyone and people were all "engaged with each other" and that I think socializing is dead. That's not it. I'm simply worried about how ubiquitous and in-front-of-our-faces these devices are becoming, and how addictive they are.

If it clarifies anything, I also don't use Facebook and I didn't grow up on television, so maybe I'm just an outcast in that regard. However, I enjoy reading and going to the cinema and I'm focusing all my energy on starting a software company. So I'm also not Amish. Call me disgruntled, maybe I am. I think I have a reason to be.

Try to convince me that most of the time you spend on your phone is time well spent. It's probably not. Well, not too long from now that shit is going right in front of your eye, wrapped around your cranium.
Supporting a dynamic redirect_uri is optional in the spec, so you could eliminate that without breaking.

In my case, because I don't enjoy programing in Java.
Most CCTV cameras are private and not monitored. You install them and have them record on a loop - old data is automatically erased to make room for new data. When something bad happens (an accident, a robbery, etc) recording is stopped and the existing data is handed over to relevant parties.

This is far less problematic than an omnipresent, monitored, shared, catalogued and indexed in perpetuity, video system.

Not surprising when their phones and the apps on them have millions of man-hours of work put into making them interesting.

What is surprising (at least to me, non-smartphone-owner) is that it's seems to be considered socially acceptable to put real people on a level playing field with them.
Pay Transparency: Is There Such a Thing as "Too Much?" - Salary.com Business
The ease of adding graphics and novelty information to the receipt inside the printer, wireless, cutting hardware, rate of printing are a few things that come to mind.

Its proprietary hardware in a sense.
The Prius doesn't look the way it does, because people let it slide. They look that way, because they want to make a statement and be seen.
Out of curiosity, how will this affect the other members of the LaunchGram team?

I need this. Design of the product is very different from design of the landing/marketing pages. If it turns out as nice as it looks then I am sold.
"Privacy and ads are a huge issue for me (and the reason I will not own one)"

Has there been any indication this product will have ads? It is a paid product, unlike Google services. Google's products so far haven't had any ads in them.
The whole point of models is that they look good no matter what ridiculous crap you put on them.
It's like renting a hotel room and then running the water/power/etc. 24x7 (and via cable to outdoors to power a factory for your 24h stay).
Any startups here operate with similar transparency? How do you plan to scale that out later on?

"The real question for SumAll, and organizations like it, is whether the approach scales beyond the start-up phase. Will the 9 fixed salaries work as the number and diversity of jobs increases? Will this approach work globally or with thousands of employees? Will the corporate culture change over time and be less supportive of pay transparency?"
Depends what you mean by startup. If you mean some kind of infinitely replicable business (e.g. a cleaning company with subcontractors doing the cleaning) then it contains: a specific and workable business plan, a domain name, a list of potential customers/sources of the same, a company registration, a cheap mobile phone, some web hosting with an open source/simple tool set up to run the business – fuck, I just realised I invented franchising.

If you mean a scalable software business (of the sort HN usually means when they refer to a startup) the problem is that execution >>> ideas, and so no-one would sell such a box for less than it was worth, unless they were desperate. Then they'd sell part of it to a VC ;-)
Thats caused by the material, not the gun. The kickstarter says they use standard ABS/PLA 3mm plastic for the material.

The first rep-rap 3D printer used a tweaked hot glue gun as the extruder.
I saw a girl in a bar in SF wearing them. She was a Google Glass model, and it was her job to wear them in public to raise interest.
Also the whole open source movement depends on copyrights.
>We do not actually provide a lowest-common-denominator.

This actually is the reason I keep away from Xamarin, and I guess I'm not alone...

I think that there is a room for having a cross-platform lowest-common-denominator, including UI, File system, Networking, etc... with ability to dive into platform specific details when needed.
Also the Amazon reviews of that cash drawer say you plug it into a printer.
But you told me Linux sucks...

http://www.ruchirablog.com/love-windows-linux-sucks-2/

Also, this is just my opinion but I feel like notepad++/wine is a wasted combination when there are so many better multi-platform text editors that are available for Linux.
Those kinds of cash drawers tend to just have a RJ11-style port that the printer can plug into and trigger whenever something prints. They're very dumb devices otherwise and have no wireless capability.
I love it. Unfortunately, it wouldn't work where you need smartcard chip readers. A lot of the world outside the US uses smartcard + PIN — I can't imagine America is too far behind. Hopefully they have that under development.
If you like working with LibreOffice but you hate printing a LibreOffice document from MS Office just save your document as pdf and you will be able to print this from any Windows/Mac/Linux computer.

A good alternative to Notepad++ is SublimeText 2.
I am curious where they purchase 4TB disk for $195. That is less than half of most places. That's quite a price break, even if buying in bulk.
A separate one than submitting our email via the site?
I have witnessed somewhat normal network situations (being connected to XMPP server while connecting / disconnecting to a VPN server) that have caused a stable and mature Jabber client (psi) not actually send messages even though it seems that it did successfully send them.

For a mature messaging protocol, that smells really really bad for any serious use.
Is the same thing as people trying to buy a Ferrari. Demand vastly exceeds supply so they will have no problem finding people that will think nothing of spending that amount of money. And frankly speaking $1,500 is not a lot of money. If you are poor or stingy I guess it is but at this point in time they are not targeting cheapskates.
I hope they give one to David Brin ASAP.

The "Linux sucks" article is from 2010 and the OP switched to Linux in ... 2013. One can change his mind over time.

The scrollbar (which I assume what is you meant by "sidebar"), as a UI element in general, seems to be getting increasingly less coherent. Like several other sites I've seen recently that are getting "creative" with scrolling, the top header on the new Yahoo page doesn't scroll, but the scrollbar still extends to the top of the page.

Regarding OAuth2 it should be noted that one person quit the OAuth2 board/spec in disgust saying how lame and insecure the whole thing was.

And nobody listened to him. And he was right.

Some things are too complex to ever be secure and OAuth2 seems to be one of these things.
This is a pretty cool deal; nice to see an open-source powered company that has found a self-supporting niche.

It will be interesting to see how they strike a balance between making money and keeping things (like Mono.Mac, MonoDevelop, etc.) open... and if they are able to build a community of outside contributors around the open-source parts of their solution(s).
The downloading seems to be halted on my Mac. I'm using a case-sensitive partition. Does this matter?
This is the first time in a long time I've seen a TLD hack that's actually appropriate and makes sense.

I can see myself using this quite a bit actually. I've been looking for a Sketchup for circuits for a long time and I think I've found it. Good work!

Can't wait for the PCB ordering phase to kick in. I've sent out to a number of shops in the past, but the quality ones are really expensive (considering the small order sizes) or their silkscreening leaves a lot to be desired. Sub 3mm traces in particular suffer quite a lot. I hope this can deliver a better product.

The contract reads:

"The Federal Republic of Germany, represented by the Federal Ministry of Defense, the
latter represented by
The Bundeswehr University, Munich
85577 Neubiberg" (yada-yada-yada)

The contract is between a U.S. corporation and the federal government.
It has to be legal, because the German Army uses some American Weaponry (e.g. the M82 sniper rifle).

And as stated in the FAQ: This has been done before - numerous times.
How is it different from any other industry ever?
This kind of traffic optimization happens more frequently than you might think. Particularly among CDNs.

CDNs don't optimize solely for performance. They optimize for a balance of performance and cost. That means saturating a given 95/5 link for 5% of the month, and then mapping the traffic away right before it starts to get expensive.
Write a C++ application called pptoken that accepts a C++ Source File on standard input, executes phases 1, 2 and 3 of the Phases of Translation (defined below), and describes the resulting sequence of preprocessing-tokens to standard output in the specified format.

In all seriousness, is this a prank?
It's very good and all, and I'm glad more people are switching to Linux for their desktops (I mean, THIS is the year of Linux on the desktop, isn't it?).

But seriously, the rambling about printers and Word... You are not supposed to use Word files as a platform-independent Portable Document Format. I mean, for that we have, you know, the Portable Document Format (euh... PDF), for example. Just export to PDF and you can print it wherever, and it will look just fine.

Also, running Wine for Notepad++ seems... excessive.
I've tried really hard to get a mix of seasoned and newcommer speakers :) Have so much excitement in the quality of the lineup.
This directly competes with Revel POS: http://revelsystems.com, though pricing isn't visible on their site, I would believe that Square's offering is also cheaper -- at least to get setup.
The scary thing is I remember reading about people buying and then GC/MSing the drugs promoted by spammers. 10 seconds of googling doesn't find the result. I think they were mostly real/safe, although some were somewhat under-strength.
