Sadly the list is missing my favorite math book, "Linear Algebra Done Right" by Sheldon Axler. It's an absolute must if you are learning linear algebra and want a deep understanding of it.

Rather than make you grind through mechanical operations on matrices, as most books do, this book takes a coordinate-free algebraic approach and does an amazing number of things with it, cutting directly to the chief insights. There are ninja proofs in this book, 4 lines long, showing some deep and useful thing about linear algebra that other books would spend pages proving in a very verbose and uninsightful way.

It is optional! Personally I'd rather the second factor was a little more dependable, the 2nd factor for my LastPass account is a lookup grid. That piece of paper in my wallet is unlikely to run out of battery power or otherwise malfunction, and doesn't have the potential privacy issues you highlighted.

Interesting... it takes money for donations for each transaction, but it's not dependent on the size of transaction. So each time you use your credit car it will "randomly" donate $0.01-0.99 to a charity?

I could see more people signing up for something like this than traditional "10% of gross income" that people tend to promote.

OK so it's been pointed out to me that HTML5 didn't deprecate target=_blank like I thought. It was just XHTML that removed it, and my method uses HTML5 'data-' attributes. So it's pretty irrelevant, just carry on using target=_blank I guess?
Ask HN: What do you want from local retail products search/discovery service
Been focusing my attention towards how online service can help offline shopping I've been trying to clearly understand what this area is missing or could use so it simply doesn't become just another "search comparison" industry. To build just the search engine is obviously not enough - other than results of the search you need to provide excellent "pre-shopping" experience. So I was curious if anyone have thoughts on the problem, limitations, or anything related for the online2offline aspect - any personal frustrations, wishes, maybe even recommendations, etc.
I think this company is a customer of Boeing's. Boeing builds their satellites.

As for the airlines, they are so heavily regulated that they might think twice about filing official comments on stuff like this without permission. No doubt FAA and FCC are talking about this even if it's not official. Their offices are only a few blocks away.
If anyone has questions about what it is like in the prgram, I would be happy to answer.
HP needs to completely open up the application and extension aspect of webOS. As a pre HP Verizon Palm Pre phone user, I find the app store to be extremely lacking. You don't have anywhere near the number or quality of apps available on other platforms to choose from. There needs to be a substantial developer base for webOS to really take off. I have used the Palm SDK, and I think it could use some work as well especially in the area of device hardware support.

The buyout of Palm shocked the system a little and the wheels are looking like they are starting to roll. Hopefully HP decides to leave their devices as 'open' as the Linux based webOS is.
Heads-up for those with a penchant for ignoring the small print... IE9 RC will replace IE8... iow, there's no obvious way to install them side-by-side. As if anyone would really want to do that /sarcasm.
Ask HR:  Review Lissn, my bootstrapped minimum viable product 
Lissn is an instant conversation platform I launched at TechCrunch50. I have since stripped it of all its features and now re-releasing it as a mvp. I would love your feedback.

http://www.lissn.com

Lissn lets you chat with random people around the world in groups of 3. Everyone is anonymous and anyone can Lissn. People can see 2 things about you automatically: Where you are in the world & what site you came from. It uses Chatroulette/Omegle mechanics and we are releasing one new feature every week. There is no signup, you just begin.

I would love to hear your thoughts and feedback. If you enjoy it, please upvote :)

Thanks

for all of WordPress' open sourcey, socialist, hippy goodness

Now I don't think socialism is a dirty word, but saying Open Source is socialist is wrong. If anything it's extreme Libertarianist. It's saying if I give you something, you can do whatever the fuck you want with it.

Open Source is not about the government, or any other organization, providing institutionalized software for the good of all.
It's not clear from that page, is there any limitation on the powers of the application-specific password? While it's less likely, if one of those passwords gets stolen can your entire account still be accessed including your account settings?
I may be preaching to the choir here, but you should really read these docs.

Obviously "everything runs on it" is no longer true.
That's definitely true, and I guess it does feed back into decisions at earlier rounds (i.e. will you accept liquidation preference and a high series A valuation which means your only future exits are at bubble valuations?).
Not sure I agree. I'd say "measure both". If people use it, it clearly has value to them, and that's very interesting whether or not they're more likely to pay. There's a big difference between "useless" and "useful but not something people are willing to pay for with the current pricing/upselling scheme".

I use Google Voice, so I imagine Google already knows all my numbers.
I don't want e-mail/sms updates. I'd want the information to show up on my calendar.

But also, I'd want the information to be accurate, and such package tracking information as is available where I live doesn't seem to be accurate.
Note that at least the $4.30 MSP430 does seem to have open-source support, e.g. http://mspgcc.sourceforge.net/,
Okay, thats pretty encouraging :)
You're the guys running minomonsters aren't you? Hows it going? I had a wander around the site a couple of days ago and its looking incredible!
We peaked several years ago at around 100k credit card transaction a month, but that line of our business is in an area that is in decline generally (I don't want to go into detail since I'm not a spokesman for the company, but basically it involves selling something that some very big and powerful companies have a strong interest in making free as it is a compliment to their products).

I suspect that the smaller companies like us will be out of this line of business in a year or two, and even the big players will be out of it in 5. Nowadays we're down to about 20k transactions a month.

Back then, it was worth it both for cost and flexibility but now there are a lot more options so I'm going to reevaluate.
I switched from the pain of developing Ruby on windows to a 13inch Macbook air with 4Gb of ram and am loving it. I do ruby and mobile development on the machine and couldn't be happier.

This point hasn't been stressed enough ... it is hard to get people to pay you for making things work flawlessly ... really hard.

Either they let you go and have an 'oh shit' moment as your replacement flounders ... or they just won't take you seriously because the stuff you do isn't visible to them ... you have to make a detailed and provocative case, basically outlining what happens if you leave, to get what you want.

The "Barcode Scanner" app is so ubiquitous it seems built in, but I don't think it actually ships. I seem to recall an actual Google Video demoing it as well, but I'm not quite sure.
Transforms yes, transitions no unfortunately. Also, no 3d transforms, just 2d ones.
I love this document. This stuff is my porn.

That said, I'm having quite a hard time grappling with section 4.

First, what is the 'users' keyword all about in the "bad" area?

Second, why is ORM the "bad" approach, and manual construction of SQL strings the "good" one? It seems to me that the abstraction and centralization of query language is paramount (examples: to afford oneself an easy one-day migration to GQL/BigTable, or to a document-oriented database like MongoDB or the upcoming Couchbase).
Sherry Turkle's interview on the Colbert Report (http://www.colbertnation.com/the-colbert-report-videos/37124...)
tl;dr - Article goes into how you have to either limit the API or charge for it... Then says that they instead... Charged for it! -sigh- Not that unique. Okay, they charged for something else and that came with it... It's still charging for it.
We're also doing it for every device imaginable. Just haven't launched the others yet. ;)

We do have a WebSockets API that OP could hit and write a Chrome extension against. E-mail me (jonathan@boxcar.io) if you'd like access to it.
This sends chills down my spine.

Allow me to rephrase that: Eventually the machine will better diagnose your symptoms. More accurately then a human doctor could.
That's a great point. My thinking about metrics got noticeably clearer after I discovered GQM.
One interesting observation, which I don't intend in any way to diminish the significance of this achievement, which I think will be seen as one of the most important milestones in the development of computer science, is that today there is so much information on the web that even Google with it's non-NLP algorithms can "almost" answer Jeopardy questions.

There is an archive of past Jeopardy questions here :

http://www.j-archive.com/

Try choosing a question and typing the category + the clue verbatim into Google. I've tried this a few times and in most cases the correct answer was in the top couple of sites (usually in the summary text on the Google search page).

Of course there's still the problem of actually extracting the answer from the page and presenting it in the proper form.
Thanks for posting my link, codeslush.

Hey nhangen, as I mentioned in that link, I would be happy to pass along any questions or comments that you might have about the CMS to the developer!
you did it!
Maybe I should restate my question, but first - yes, we have a working product/service and yes we want a CTO. We have a strategy, support network, growth plans, ect and are executing them appropriately.

My concern is less about " Hey guys, help me out finding a free developer" There is nothing 'free' about our job position and I'm not looking to scrutinize the semantics of the job title. As we all know, we all wear multiple hats. You can call the title what you'd like, but our job description is clear (posted on startuphire).

My main concern is that during our process of finding the right candidate, I've noticed a dwindling talent pool. I am new to the Silicon Valley area and expected those resources to have more exposure in the area - through networks, meetups, ect. Being the new kid on the block, I feel like I am missing some cool hangout that everyone knows about or something.
I'd settle for a decent Sean Connery impression.
Could use a little more context, examples etc. Good but not perfect.
> but they're doing it at a better price, with far better distribution than Apple currently has, and with features that Apple hasn't managed to launch yet.

The price has not been announced and the Apple iPad 2 will release before this device! I think your enthusiasm is a bit premature.

My question is how many mobile operating systems can the market really support? Apple has a huge lead in both devices and apps but Android is catching up fast. The Touchpad might be a great device, but what good will it be when all the cool apps are on other platforms?

[Edit: Added not]
I know the military checkpoints - I spent some of my childhood there and still visit every few years. But these aren't "military bases turned beach resorts".
Maybe it's just me, but I haven't had a good experience with career fairs - too many people and it's difficult to stand out. I prefer reaching out to someone in the company, in our school's alumni network or asking for a mutual introduction. Hacker News has also been a good source of leads.
One scenario I've heard is that Sarbanes-Oxley might be partially repealed to make it easier for these sort of companies to go public.

I'm not sure whether it's the S-O that's actually keeping companies from going public now.

An alternative scenario is the rise of a hypothetical trend in listing on non-US exchanges.
Is this really a pressing issue? Considering all the other shit that's going wrong with the U.S. today, does a lack of 4G broadband coverage really merit this money and attention?
Agreed. This post is from January 2010 and she had been there for six months. When did they start?
Wordpress codebase sucks by all accounts, I'm just wondering if this is related to PHP or we'd see something like this in every non-framework code, regardless of language.

The posting on Startuphire will help clarify some questions about who we are and what stage we are at. I left the url and description out from this post because I wanted the topic to be less about our company, specifically, and more about the talent pools, networks, and meetups that are in the area for people to connect, talk, and find suitable candidates to join our team.

The startup has a working product/service and generates a modest amount of revenue. Those details are private. The startup is 1.5 yrs old and has thousands of paid customers.

LADR is in fact in the hall of fame: http://math-blog.com/mathematics-books/
This is the first I've heard of this, but I think it actually makes a lot of sense. This allows HP to market WebOS as a true phone/table/desktop OS much like Apple now does with iOS and Mac OS (especially now with the Mac app store). They already have their TouchSmart shell with "TouchSmart Apps" and games, so this is a very smart move.
If the new stuff replaces more expensive old stuff, a recession can make it even easier to grow a new business.

Software that makes a person 2x more productive is very attractive when everybody is trying to do more with less.
Look at the markets they sell to. 37Signals needs to remain professional and appear competent, because they routinely buck established business "truths" and this draws attention.

I wouldn't listen to a person telling me they have a better way of conducting business from inside a green tent. Sorry, I'd think they were an immature kid...

...which is exactly why Zappos' approach works. They distribute a hip, cool product to people based on other businesses' reputation. The only thing they need to do is ship something once the right way to convince a retail customer they are competent enough to take a pair of shoes (or whatever) from point A to point B.

People have very different expectations with regards to the deliverables of the companies. The office space simply flows from that.
Why Twitter is so valuable
My college didn't have a college bowl team, but competing on high school teams and being responsible for more than a few correct two or three word answers, I can vouch for this.

It's all about having enough breadth that the other bits of information presented can help whittle down answers by way of association and relationships. Good trivia players rely quite a bit on intuition.

Ken Jennings mentioned (in his book) how Jeopardy! often has questions about rivers, so it was a fairly simple matter to just memorize river names and some basic associations with which to answer questions.

It seems like Watson is mostly a really sophisticated algorithm on top of lots of brute force (2880 processors?!). Though I guess it could also be said that humans are just ugly bags of mostly water.

That said: in something like medicine (differential diagnoses), such a system could also be extremely useful, given the frequent occurrence of a fairly limited number of "answers".
I don't know that this answer is in the spirit of the question you're asking, but I think anyone who does software development for a living needs to know at least the basics of vi(m).

If it hasn't happened yet, some day you're going to find yourself logged in to an unfamiliar Unix-y system's console and need to edit some files. You may not be able to start X and get to your favorite GUI editor. Emacs may not be installed and you may not have the authority or time to get it installed. (Side question: Do any Linux distros install Emacs out of the box?) But vi(m)? Yes, it will almost certainly be installed, and you're going to want to know how to use it then.
Introducing the File Finder
It wouldn't surprise me, when watching (and playing along) I often start saying the "What is" or "Who was" before I have the answer.
This explains a lot, but thing it doesn't cover is why the patch for Rails ends the session when a CSRF token is missing.

I'm guessing this is just extra paranoia, but it opens an obvious attack to log people out of a site maliciously.

Any ideas on that one?
We (if you'd allow me be presumptuous) don't want to upgrade to windows 7 just to test websites in IE9 ...

When MG Siegler uses title superlatives, such as "Brilliant," "Genius," etc., you can usually replace them with NOP. ;-)
It's weird that this isn't on the front page, 40 points in 2 hours, did I miss it?
From my experience here, I would add:

7. Don't just direct everyone to your web site. This ties in to some extent with #2. If you're not meeting the students, setting up interviews, holding info sessions, etc., then your physical presence is superfluous and distorts students' expectations of career fair.

8. Don't say you're looking for students from all majors. You won't get taken seriously. Maybe your company really does have openings in every field this school offers, but USPTO is the only employer I've seen who can even come close to justifying this claim.

It's also worth noting that students (here, at least) talk to each other about the recruiters they've encountered. Students remember really good recruiters and those who make serious faux pas.
Arguing that consciousness and the brain is different from deterministic algorithms, or neural networks is perfectly valid. It doesn't show lack of understanding of AI. Just that the debater is not an adherer of strong AI functionalism.

Using Gödel's incompleteness theorems one can argue that no set of algorithms is capable of perfectly modeling human consciousness. A logically correct algorithm can not give faulty output, yet internally conclude that output to be correct. We do not make the same mental steps as a set of algorythms: I can't say this post is correct with a 97.77% accuracy. In fact I wonder if you will respect me more or less after this reply, if you'll believe I lack understanding of machine learning... not if I passed the Turing test for intelligence or not. Calculation != Intelligence.

Like the robot in the Chinese room is still a puppet, that doesn't really understand Chinese. Attaching a radar to a flying drone doesn't make it feel or act like a bat.

Much of AI is still Advanced Informatics.
Fortunately, the attack is limited by the fact that the attacker can't see the response from the server. If the attacker could view the response, it would break CSRF protection based on nonces as well.
This is interesting. I'm curious, why did you decide to strip all features and re-release as a mvp?
This is so difficult to follow.

1) Who hosts the flash app? The site owned by the attacker? Or must the flash app be maliciously uploaded to the site being attacked?

2) And seriously, the final result of this scheme to to make a post to "www.victim.com". Doesn't "victim" mean someone who is exploited? I would expect that data would be taken from a victim, not posted to a victim.
I really actually am actively rooting for them to fail because of this ... does it make me a bad person?

As the article says, it's taken no funding. Marco said there would be a point to being a subscriber, it's extra pain on top of having a mobile device that isn't from Apple. My words, not his.
I've noticed something very tiny: Using the Windows Classic theme on Windows 7 x64, the close button of the Favorites Bar (the black X with the mouseover text "Close the Favorites Center") isn't displayed properly if the bar is very slim.
Oddly on Windows Server 2008 R2 x64 this doesn't happen, because here the Favorites Bar has an extra button "Add to Favorites" and the 'X' is on that button's row.

(nevermind the "InPrivate" in the left example, in the normal mode the bar looks exactly the same)
Yeah, I was having a hard time reconciling this:

The obvious choice would have been to either limit the API or charge for it. But neither of those are very appealing options to Arment. Limiting the API leads to half-baked, "fragile" apps, as he calls them. Charging developers for API access or taking a cut of their app sales is tricky from a financial perspective, he notes.

with the following paragraph:

Instead, Arment came up with a smart third way of doing things. Thanks to the subscription test feature Instapaper launched in October of last year, Arment has a way to get paid for API usage -- sort of. You see, the only way users of any service can get access to the Instapaper API is if they’re paying the $1-a-month subscription fee. In other words, Arment has just ensured that he gets directly paid for people hitting his API. And he has just given plenty of users a reason to subscribe. Smart.

I suppose he's not charging developers for API access, but charging customers for something isn't something novel. (I love Instapaper, but this article is just weird).

Quora has the benefit of founders with a solid network, so the early adopters are heavy hitters with interesting things to say. It's a shame, then, that the user experience is just so... tepid.

I'm not really qualified to comment, as I've only encountered Quora via deep links, and sometimes some additional clicking around. But the above summarizes my impression, both from my own limited interaction and from the limited amount of "the buzz" [1] that enters my personal world. Quora became the next cool, limited, (temporarily?) high S/N place to be, after the previous one became too noisy.

--

1 Oops, no pun intended. Although, OT, I have been wondering whether Buzz is going to "make it", longer term, or whether it's already on or being considered for a near term hit list (e.g. Wave's fate (but without an open source spinoff that I can imagine)).
The twist is that he is charging his users for API access - normally it would be a convoluted process where the third party developers pay to use the API, then they try to monetise the users via subscription or ads. This is a smart way to do it.
