Ask HN: What's wrong with current advertising system?
In "Startup Ideas We'd Like to Fund" by Paul Graham (http://ycombinator.com/ideas.html) one of the idea is 12. Fix advertising.

According to you what's wrong with current advertising systems on web and mobile? What are the major pains for both advertisers and uses? Do you know of any startups with innovative advertisement model?
I see this site as an illustration of a lean web startup style applied successfully. I don't get the feeling that pg et al. are planning to spiff it up with a fancy UI any time soon. I agree there are some usability issues that could be improved.
Going by Engadget, a bit thinner than the iPhone 4 supposedly.
In that case, while adding fake BTC will not let you actually withdraw coins, it would allow one to issue mass sell orders and crash the price for BTC. Then the exploiter could purchase them at their lower valuation.

'Sell' fake coins. Crash the price. Buy 'real' coins. A virtual coin laundering. Fascinating.
if it makes you feel any better, it's quite new..maybe a couple weeks. PG posted about it at the time.
RIM cuts 200 jobs in Waterloo, reports say
It would be an interesting situation for Nokia. First they announce that the company will be bet on Windows Phone, Symbian gets axed, and MeeGo will be put to the background. Many MeeGo developers saw the writing on the wall and abandoned the ship. Hiring them back would be difficult...
I am aware of the current opportunities.

I think you (and most people here) underestimate what the "old web" could imagine, though. We had all sort of ideas for agents that would go out and grab and analyze data for us in all sorts of clever and interesting ways. Search engines got built, as did one or two other things, and then the web just got too complex.

Hell, even I had a simple app that went out and grabbed all my favorite comics and showed them to me, nicely formatted, and without ads.
Intimates that hiring persons that use Linux will result in "a third" of company infrastructure being surreptitiously converted away from Windows among many other ridiculous claims. This article is disgusting and shows that PC World's readership is primarily tech-illiterate bureaucrats. It panders significantly to that group. The section "The Voyeur" makes no sense at all, as the supposed good guy displayed a random employee's screen to demonstrate some corporate spy tool to a group of executives, and the supposed bad guy was updating his resume, yet the latter is accused as "the voyeur". The whole thing is basically an article for SolarWinds, which apparently makes software that only scared executives buy. There is a comparison between Terry Childs, the SF admin that would not give the passwords to city routers, and Hitler, as "[they both thought they were doing the right thing]".

Just a terribly offensive article to anyone with any degree of technical sense. It is obviously written to scare figureheads and MBAs into distrusting their IT department (and therefore buying a bunch of software that is supposed to "watch the watchers").
Thousands of “hackers for good” build applications for humanity
Exactly. If I see the price of Apple drop precipitously, I might think that somebody is manipulating the market, but I'd be a fool not to buy it at $5/share.

Also, what if it wasn't an attack? What if someone with a lot of bitcoins was running a malconfigured script? We've seen flash crashes in the real world caused by automated trading; why would btc be any different?
Expired links are the result of Arc's web server reclaiming stale continuations. It's a side effect of creating a web application using a continuation-based server.
> I read it as he was watching a market free fall

Yeah, I think initially there was that. But after he bought he began to suspect there was fraudulent activity. And he still transferred the money out. The problem was not the buying, it is suggesting the MtGox is responsible for providing him with a free lunch now.

> wasn't the same . . .

No, but there was a commonality in that foul play was suspected. The point of the car analogy is not the appropriateness of the forum, because MtGox is unquestionably an appropriate forum. It's about how much evidence you have to suggest that something is amiss.

> What about people who had standing buy orders

We're (I'm) not talking about them.
No, please spare us from infinite scrolling. :(

However, I agree that it's annoying to have to reload the page before being able to click on the rapidly-expiring "More" link. I often click on a good number of stories on the front page, and by the time I've read them and get to the "More" link, it will have expired. Then when I reload the page, I'll have to rescan it since some new links will have shown up in the meantime. Then when I click on the "More" link... expired again!

How about a bit of caching? Maybe taking a snapshot of the top 5 pages or so every hour? It wouldn't be up-to-the-minute, but one would be able to scroll through a list of links with a consistent relative order (rather than reencountering the same links as they move up and down.) Maybe the cached version could be offered as a separate section of the site, up there with "new", "threads", "comments", etc.
I just had a friend tell me that he stores PORN on Dropbox.
Nokia's CTO, Rich Green, on Meego back in February after Nokia announced the shift to WP7:

http://www.youtube.com/watch?v=ISjb9E5A2ls

That is, this will be their one and only Meego phone, and they want to "get feedback [for] inclusion in their [WP7 phones]".

This looks like a great phone and OS, and I would actually buy it if Nokia were going to support it.

But they just don't get it, do they?
From the message board:

"Folks, in the grown-up world, trades are unwound when the market malfunctions. --Jeff Garzik, bitcoin core dev team"

In the grown-up world, currency is controlled by governments, the financial industry is regulated, and money cannot be transferred large distances anonymously. The whole sales pitch of BitCoin is that it is free of all this control. Invoking "the grown-up world" to describe BitCoin is absurd.

Gotta love any useful-awesome-open-source technology, but I'd also love to ask the following question: how does this differ from Sencha Touch? Is it library versus framework?

Obviously, I know the two differ, but I'm not sure of the benefits of jQuery Mobile (besides developer mindshare (which is nothing to be sneezed at)). I use jQuery lots in (clients') smart websites and I use ExtJS/SenchaTouch for RIAs. Is that breakdown still valid? Has jQuery Mobile become a consistent, unified development platform for RIAs? Or is jQueryMobile an awesome mobile Javascript library? Or am I missing some greater point? (<- likely)

Ask HN: Visible Comment Scores - My Biggest Problem
Okay, I know.. showing/not-showing comment votes has been rehashed in at least a few front-page posts at this point.. but there's one effect that I feel hits me the hardest with the not-showing-votes change and I'm not seeing it talked about. So, I'm wondering if I'm alone.

Bottom line is that since the display of comment votes was suppressed, I feel like the inertia of early comments is too strong. In summary, I believe there is psychology behind voting on comments whose scores you're aware of that allows users to evaluate the proximity of a comment's score to the 'right' score for that comment.. as opposed to making just a boolean thumbs-up or thumbs-down decision on whether the comment is good or bad without relative context. It's flawed.. the point of the scores are to seqeunce the comments, so not being able to see the scores leaves the reader without any context for making a decision.

Here's how it affects me: I visit the comment thread on a post early-on. Maybe there's 6-20 comments, I get a sense for how the discussion is going and if the story is interesting to me I often want to revisit later to see what people have to say. Since comment scores were suppressed, I'm sure that the likelihood that the comments at the top of the list are much less likely to have changed. That is to say, there's a greater weight now placed on commenting early, and it's hurting the ability for voting to reflect the quality of the comments in the thread. I'd expect a system to stabilize and for the comments scores to become more useful and relevant over the life of the thread, not to begin polarizing in the very beginning of the thread's life. I think this is the biggest fault of the comment score change, and the reason it ought to be undone.

It ought to be provable. I'd posit that if you were to look at timestamps of comments before and after the change you'd find that it's now much more likely for comments with very early dates to appear at the top of the list than later ones...

That said, I feel like if I'm gonna complain I ought to provide an alternative. The comment scores are hidden for a reason, so what would I replace them with? I'm not sure. I've seen or imagined a couple of things that I think are worth trying. One is to quantize the displayed comment score.. "0,1,5,10,20,50,100" or something. That's an interesting idea. Another thought that intrigues me is to weight the comments score by the karma of the scorer.. giving well-respected user's more say in the value of a comment. I wonder if a combination of the two might help us arrive at the 'best' display of compelling comments the fastest.

At any rate. </diatribe>
I'm not sure, but I think we may have just gone nuclear...
side effect is a kind way to put it.

Serving links that break in such a short time is a bug. I'm sure there's plenty of simple ways to make that link work as expected. I haven't looked at the Arc code, but I have implemented pagination dozens of time. Never with links that expire though.

The continuation style seems to imply that "next page" means "the next page of results from the time you requested the initial page". Which doesn't really have to hold true. It'd be better to just give the users more links. (As I said previously in a feature request)

Not that I believe infinite scroll is the right solution though.

[edit: This reply doesn't really convey the rage I feel when I get one of those expired links. I'd tear limbs off a developer for that...]
Ask HN: is it possible to build large scale systems that are secure?
The huge number of hacks recently seems to be pointing to the possibility that it is not practical to build truly secure systems, especially at any sort of scale.

There must be massive opportunities for entrepreneurs who can address parts of this problem.
Someone has to code that feature. That takes time.
There's a lot more to this town than just RIM. I work, for instance, at the Institute for Quantum Computing, which is just one of the things that UWaterloo is pushing forward with. I'll grant you there's probably going to be some real-estate price crashes, but I don't know if it'll be as bad as all that.
So if I get word that Anonymous is planning on doing another blitz trying to create a rumour that Steve Jobs has died, would I be wrong to short Apple? It doesn't matter whether the forces moving the market are legitimate or not; you can't be faulted for playing it. What you're advocating might be moral, but it's not in keeping with the principles of a free market.

If you were making a movie would you rather have 5 A-listers or 1000 extras?
The web hasn't taken enough advantage of the technological advantages it has over TV. So what I'm thinking is more in-depth on page commercials with the ability to checkout (even one click checkout). The call to buy should be more aggressive overall.

That was a great read. If I was Kevin I would give the coins back and not do business with MtGox any longer. It's clear their systems are not secure enough to handle these kind of transfers. It wouldn't surprise me if MtGox was influenced by organized crime, they are in Japan and the Yakuza love these kind of quasi-legal schemes as of late.
When a page is requested, some of the links (fnid=X) map to functions on the server that are held in memory. The id (X) is a key that is associated with a continuation for a specific "session".

It's not a bug, but a feature of Arc and other continuation servers. If continuations aren't reclaimed by the server (and those links invalidated), the server runs out of RAM.

In angers me slightly when I get an expired link, but I like getting expired links rather than items from other pages that I've already seen, like reddit. That is truly maddening.
What bullshit. I send them money and they don't use it and instead give it away to some unrelated third party?

Assholes.
I think it is, but I think security has to be architected into the system from the beginning, and you have to be willing to pay the price in flexibility and development time that that introduces. It's not really something solvable by entrepreneurs, other than security consultants (which is a booming but not all that scalable business).

Building secure software means that you have to think carefully at all levels about precisely what inputs may enter your software, and gracefully reject anything that you're not prepared to handle. The flip side is that you can't easily readjust your software when business needs change, because you've built your system to avoid unintended consequences and everything has to be specified out in careful detail.

The reason systems aren't secure isn't because they can't be - some very secure systems were built way back in the 60s (eg. Multics). It's because it's not economic for them to be. Insecurity is a conscious design decision, and for many markets, it's the right choice.
Advertising is bad because it doesn't positively contribute to the user experience. Advertisements should inform you of something that you either A) Actually want to buy or B) Want to know about. They don't do that.
I think you may be able to argue that it is partially a bitcoin problem because it has been claimed that this attack was based largely on hacked bitcoin accounts (via virus/worm). I think this problem can be solved in the future quite easily though.

Bitcoin currency collapse - where next for digital cash?
After attending 6 different talks about GPUs from various researchers today, it's pretty clear that most the people I've talked to pretty much just use Cuda. The general consensus was that OpenCL has a lot of overhead from setup and less performance despite being more flexible, and nVidia is much more active in actually courting researchers, often handing out machines for free.

Some of the speedups especially for quantum chemistry and other "embarrassingly parallel" computations is pretty nuts.

Bitcoin's own site still isn't saying what happened, but it looks as though the servers of one of its "Bitcoin-to-real-money" gateways, known as Mt. Gox, were hacked. Badly-hashed passwords were stolen and useable logins recovered. Uncontrolled fraudulent trades then quickly pushed the real-world value of Bitcoins close to zero.

This would make no sense if you supported a decentralized cryptocurrency, but would make perfect sense if you were worried about losing the ability to cash out of your penny stock of choice when, due to freak coincidence, a separate scam targeting the same stock imploded prior to you being able to unload the shares you had acquired for fractions of a cent at $17+ each.

The Bitcoin "community" is an emergent, distributed boiler room. They could just as easily be selling pink clam shells, tulips, or shares in an insolvent company that had a business plan to make pool cleaning agents. The underlying commodity doesn't matter. What does matter is that the widely disbursing the underlying commodity early gave them enough of a following, including folks who are savvy enough to think that they are the ones getting rich off the marks (a classic element of fraud), to attempt to convince other people that there is actually intrinsic value in what they are selling.

Every article about Bitcoin which makes it to HN -- yes, including ones in mainstream publications -- is in effect a PR hit planted by a new breed of the old boiler room scam.
While it is hard to believe that 100ms will actually matter, it is precisely what both Amazon and Google found out when they studied latency sensitivity in users.

Phew, thought it was about Bitcoin.

This is one nice concept. We need to think more about it. Isn't it something like "Related Products", "related articles", "Products you might be interested in" type thing?...where user can just simply choose to buy and checkout from ad itself?
Ah, that was what my assumption. In that case, you are likely targeting everyone, so you should make it very clear what the benefit of your service is. Be very blunt, maybe something like "Manage your gift-getting for any occasion".

Unspoken assumption: that competing with desktop alternatives is good or desired.

Personally, I can't think of a single desktop application that I use that is better done in a browser with the possible exception of Google Maps, and I say "possible" because I haven't seen a desktop contender.

I use GMail's web interface solely because I can't stand any of the Mac clients (at work) and Outlook isn't available on Linux (which a couple of my PCs at home run). It is cross-platform, which is a plus; it is painfully ugly and slower than a desktop alternative, which is an overwhelming minus.

I greatly prefer my web browser to be for browsing the web. While I'm all for standards in HTML/CSS/JS, I find the "web browser as your OS!" crap to be disheartening. I like things that work, and for the most part, web applications don't.
100x? Add another zero!

The main prize in the Friendfeed acquisition was Paul Bucheit, who invented and implemented both AdSense and Gmail, which together now bring Google over $10 billion in annual revenue.

They're x86 processors, but rather slow ones. The high FLOPS figures come from the custom vector instruction units, which are 4x as wide as SSE and much more flexible. You're going to need excellent SIMD support in your language to use this chip.
