Online course reviews written by current university students should be taken with a grain of salt. "Easy" has a special meaning to bright university students; it means "too many people would pass."

I once had a professor introduce me to a colleague as "He was the A." He seemed to think the remark praised him as much as me. Only in primary schools do you hear a few voices saying "90% of the class should be performing at A level".

I note that this reviewer didn't get full marks (perfect score) in the class. It's interesting to contrast the review, also on HN, from one who did. http://henrikwarne.com/2012/05/08/coursera-algorithms-course...

I read another review by a current Stanford student who complained that the pre-Coursera Machine Learning class was too easy. I wonder how he did? A close friend of mine took that course and earned a perfect score. He didn't complain it was too easy; he went back to his company and started a group to apply ML to their business. Easy/hard is beside the point. The point is: students learn.
Having been a beta-tester of DragonDrop from the start, one thing I'd like to add is how important the concept of user-interaction truly is and how Mark really innovated in this regard. Lots of Mark's friends, including myself, suggested using one of the screen corners as a hot-zone. But since most people usually have other actions associated with the corners and the extra distance required to drag the icon far from the center makes the movement tedious, Mark kept looking for a better way to handle it.

He spent weeks & months trying out different UI and actions, finally coming up with the 'shake-your-cursor' action. It seems trivial now that you see it but it was something none of his potential users could imagine. And since then, he's been refining the app constantly to get it to its current state, including the rotating background and optimal thumbnail for a variety of mimetypes. I'm so glad to see the app finally getting the attention it deserves.
I didn't read it that way at all. Instead of seeing oh it was all too easy i heard I wish it had been harder; and I didn't see any competitive thread in it at all.
I mentioned this app in a comment thread on hacker news a few weeks ago and saw a huge influx of traffic so I thought it might interest a wider audience.

It's extremely simple, type to search for what you want, double click or hit enter and the character is in your clipboard.

The main problem is speed. The fact that it takes two days, sometimes more, for a few bits in a few computers to flip, in 2012, is absurd, regardless of how many fraud checking algorithms you have to run it through.
This is just brilliant. Please create a Windows equivalent and make my whole year.
Congrats Mark! Looks like a few HN folks have already used this app in the past. How did you reach out to an audience to build up beta testers? And, more importantly, how do I make sure I'm on people's hit list for beta testing new apps?
Design patterns tend to arise due to linguistic limitations, but not always. They’re mainly a shared vocabulary for talking about software architecture and design, regardless of paradigm.

As for dependency injection: DI ⊆ inversion of control ⊆ decoupling ⊆ factoring, where ⊆ = “is a kind of”. Roughly, DI means externalising dependencies and giving them as parameters in order to reduce coupling. Which, when you put it that way, is obvious, and something we (should) do often in any language.
We're working on a fix for this right now. Thanks for the heads up!
Build it yourself, much more efficient. If you only want a prototype to show investors, etc then you can even just use Keynote.
Could someone please summarize which of LibreOffice or OpenOffice is more useful to follow and why?
Well done. This is the sort of app you look at and think "Why isn't this built into the operating system already?"
You have cool + unique + valuable core capabilities but you lack a distribution mechanism and your site communication/UI is ineffective.

Spend more effort getting the right people involved and less effort on coding. Talk to the guys below who have good landing page and virality suggestions. You dont necessarily need one of them fulltime, but you do necessarily need to listen and internalize what they're saying. Be generous with equity to solve this problem.
I've been using recruiter spam as an opportunity to promote my own project just by replying and asking them to check it out. While the total number of responses are small, I've gotten some decent feedback and made a few interesting contacts through this tactic.

History of Fedora and Red Hat Linux
Social Security is redistributive much in the same way that flood or fire insurance is redistributive: those who never need it have overpaid, and those who do need it have underpaid.

The flaw that exists in the current discourse regarding Social Security is that the program is framed as a retirement program. It is not. It is "end of life insurance". In fact, one correct term to use in describing programs such as Social Security is "Social Insurance":

I always found it odd since there was no such title card present in the Canadian or UK versions. I just assumed it was an overly cautious precaution due to operating in the stereotypically overlitigious United States.
I agree with your general thrust. I believe their founder, when asked why he wasn't moving the company to SV, replied "We could never have launched Dwolla in the Valley"

Dwolla is "old school" start up. Taking on big, entrenched, B2B problems. That just doesn't happen in the Valley anymore like it used to. Look at all the comments here "It's too hard, it'll never work, we're doomed" Not surprising but still sad nonetheless. Back to developing mobile apps.
As the article points out, they must be making good money for this attack to be practical. The back of the envelope calculation seems reasonable: even paying Google reasonably high CPMs they're making it back via Amazon through even casual browsing.

One of the issues is that legitimate affiliates can't tell when their affiliate revenue has been stolen. The cookie lasts 24 hours and any Amazon transaction occurs offsite at a later time -- they have no idea what to expect re: compensation. For that reason Amazon may not be chasing it down as eagerly as Google would with Adwords. With Adwords users can far more easily see when they're being scammed.
This is delightful. Apple, please buy this guy out like you did with CoverFlow.
Something I haven't seemed mentioned, but this makes a BIG difference for the following reason (among others):

If this was twitter that got hacked, it implies that they're storing passwords in plain text.

That news is or should be a Big Deal.
Getting Featured
Reading the description, I felt that waiting for the overloaded page to load was going to be a waste of time. Having seen the video, I am contemplating tossing him some cash.

Drag, think... doh! wiggle, store. Dig, dig, find, unstore, drop.

That wiggle makes all the difference. Come to think of it, I might unconsciously wiggle things while I'm trying to remember where I meant to drag them to.
For a while all sites that deployed "Answer Center" by RightNow (recently acquired by Oracle) were vulnerable, but it seems they've patched it.
I am an Opera user as well but I really tried to do the Chrome switch when I got a new laptop and decided on a fresh install of everything. I was thinking that it might be time to begin a new chapter in my personal browser-history-life and hop on the Chrome bandwagon. It didn't take more than a day or two until I got drawn back to Opera though.

I know it's just mostly/only about "old habits die hard" but I just feel that so much is amiss in Chrome. From small things like that I have to get an app to get a dropdown address bar list (I mean really?) or the lack of intuitive hotkeys (my favourite is Opera's ctrl + z for undoing a closed tab) to bigger things like that I have to put up with Google's constant nagging about logging in to this or that or the lack of features that Opera has out the box (like Opera Turbo and such).

An old usage case before I got a no-limit data package plan was trying to save bandwidth while tethering from my phone. In Opera I could first put on Opera Turbo (like a proxy compressing service) and with another two clicks control what elements I want shown. I could easily and intuitively turn off pictures for example and only choose show those that I may want to look at. It was great for surfing light!

I am no rockstar web developer nor am I interested in figuring out what plugins/apps I need. I just want stuff to work, out of the box, while still having access to some cool stuff. And for that Opera works wonders for me (even though the support for it ain't that great ;) )!
Wow... This is awesome. I actually did a project for my high school science fair that focused on analyzing twitter. It was no where near as sophisticated but it really opened my eyes to the massive amount of data and the availability of commodity hardware that can actually handle terabytes of data.
Tips for Optimizing Big Data
Clojure is all substance and no glitter. It's all about getting the job done, which is why it's the most important language development in 20 years.
I'd follow LibreOffice, it's more feature rich, plus LibreOffice is licensed under the Mozilla Public License and LGPL3, which means OpenOffice won't be able to use all the progress LibreOffice has made. I have a feeling OpenOffice has a very short lifespan at this point. I am however in no way an expert on either of the two, this is just what I have read over the months.
> The article shows that the site works in IE9 and IE10.

To return to the analogy, a closed store will have stocked shelves and a cash register on sundays. The problem is that the store owner doesn't want to pay someone to work sundays making sure things are ok and stay that way. Likewise, supporting IE is not just a process of running through a site once and saying, "looks good." It requires continual testing, and this testing happens every time the site changes.

Also, Chick-fil-a is closed on Sundays and they claim it is a feature. And some people are religious about browsers too.
I had lots and lots of conversations with the App Store appeal board, a plea for direct download customers to write to Apple and tell them they want the app in the store.

Apple rejected it for "interfering" with a standard system operation. What ultimately got me in was an email I wrote pointing out that the app PopClip (a great utility from @pilotmoon) was in the store and also enhanced a system behaviour.
Ha, the idea for the app or the idea for the silly sounds? ;)

Note: my wake-up sound is currently the boot sound effect form OS/2 Warp 4, just because I love weird, retro-computing goodness.
Maybe "finance" was the wrong word.

Whatever you want to call the worship of ratios like "return on equity" without an understanding of the business, that practice is dumb and destroys companies that actually create value.

Dell is a great example -- be a computer manufacturer that owns almost no assets related to the business. Their Taiwanese suppliers like Asus are laughing their way to the bank as the Dell management patted themselves on the back for improving some ratios.
Either you're changing your argument or you failed to articulate your position initially. Nothing justifies Microsoft's abusive practices; that's a non sequitur.

If we take your original statement and change "browser" to "search engine" and "IE" to "Google", we end up with this: "If any single search engine had the marketshare that Google had in its heyday, it would be irresponsible and anticompetitive for them to implement nonstandard features."

If your initial argument was that an illegal monopolist should be unable to introduce any new features, that's an entirely different statement than saying that having a large marketshare means that any new features are irresponsible and anticompetitive.
Radar can handle that problem. To be fair, probably not the automative radars they're already using, but something in the tens of GHz range could do it.
Thank you. Believe me, that video was the hardest part: a bad screencast is a terrible thing, but they're damn hard to do well. I think I spent about 4 hours on that sixty second video, and it means the world to me to know that it was well-received. Thank you.

For the past year LibreOffice has been the one worth following because OpenOffice was put on hold after the Sun acquisition, then shifted to Apache where it has now been resurrected.

My view would be that it is well worth seeing what Apache do with this, however Libre currently seems to have more active development (although I could be completely wrong as I don't know what sort of resources Apache have been throwing at this).

Given they are both free, it would seem like a good idea to pick one for day to day use, but follow both closely, much like the situation with the browser wars.
So, its like doing a 'cut' and then navigating and performing a 'paste'.

Did I miss something in the video?
Eep — traffic it seems to come in spurts. I've got a RewriteRule to send people to the App Store when I notice it being particularly bad, but I prefer to keep the site up so people can see the video and try the trial. Thanks for posting this link.
Don't anthropomorphise design. Computers are better at processing huge quantities of data in structured form. Humans are better at pattern recognition and adaption. Trying to design an autonomous robot by emulating the way humans or animals do it is a recipe for bad design.
As a former employee of one of those banks, I can tell you that you are overestimating them. They are not even thinking about keeping their enemies' close or disrupting the disruptor. Who gets paid a bonus for that??! Nobody.

Can LibreOffice use the improvements to OpenOffice? If so, it seems like the relationship could become quite one sided with LO able to pull in all the fixes to OO and use that to move further ahead, but with OO unable to re-use any of the LO work.
Forbes has been doing it for a while and @Quora retweets them all the time, so they must be OK with it.

Sure, here's a screenshot of my hourly report for the past day. Note that the site hasn't gotten much traffic in general since most people come to it directly through the App Store — that is, despite pretty decent sales, the site has historically only had a few hundred hits a day.

Out of curiosity, is Twitter data such as this freely available to anyone, or was this specially acquired for this set of students? I can imagine a number of interesting projects that might arise out of such a data set.

IMO, I agree with those that say it is a publicity stunt. It costs very little to support IE9+. Even IE8 doesn't take a ton of time to make it work, although you do have to do something about the CSS3 styles (CSS3PIE, for example.) But it is really dumb to make the choice to BLOCK a browser by user agent. How about feature detection or if you must block by browser, at least do IE8 and below.

Note, I am a front-end dev, and I know the pain of developing for IE6 and IE7. But any front end dev with any professional skills can make a site that works in IE8+ without resorting to ugly hacks (I don't call polyfills hacks.) And IE9 supports a large percentage of the standards we use on a daily basis.

Sorry, dumb move by Paydirt, with no monetary payoff.

Isn't foldr/build fusion much closer? A collection is represented by a "build" function that takes the reducer, and list transformers become reducer transformers. The main difference is that it's applied automatically by list library using rewrite rules, so it's not as obvious, the reducer is supplied as a pair of "cons" function and "init" value rather than a variadic function, and there's no parallel fold.

Upon reading this again I realize that you must not understand what a deficit is. A deficit occurs when you spend more than you make. It is the opposite of a surplus. If you earn $5,000 a month but spend $6,000 a month, you are running a deficit. The U.S. is doing this exact thing, but on a much larger scale.
A tip that completely changed copy-paste experience in Finder is "Move item here".
Copy as usual (command-c) but instead of pasting (command-v) you do (option-command-v) and it will _move_ the item.
Such as huge time saver since I use to open two finder windows to accomplish the move since I'm quite bad at dragging with a trackpad.

I can understand why you're redirecting traffic directly to the App Store, but I think it might be doing more harm than good.

I vaguely remember seeing something about this app on HN before, but I don't really remember what it does exactly. Based on all the comments here, it sounds like you made a screencast that does a great job of demonstrating the product. Unfortunately, by redirecting the traffic, I can't see that screencast (and the App Store screenshots don't really demonstrate what the app does).

This product might very well be perfect for me, but I don't know because I can't see the video of it in action because of the redirect.

Just something to think about.
I own a similar app called Yoink that does the same thing. Any reason why I should migrate to Dragondrop/does DND do some things better?
I think it's more critical than just having less IE users in that space... The thing is, 1.6% of total traffic does not equal 1.6% browser usage.

If all your IE visitors are seeing is a landing page and a message saying "sorry, we're too lazy to support for your browser", then of course they'll turn around and never come back. If they were to let IE users through, that number would most likely jump up - significantly.

I know a couple of hardcore IT guys and programmers that are really happy with IE9, and hate Firefox and Chrome with a passion. It happens!
This is an excellent app, but I suppose it works best with a mouse. Using the trackpad is a bit of a pain, maybe it could have been nice to fire up that box with a shortcut?
I'm on iPad and even though I tried to see what this app is, I still have no idea.
This web service asks me to login using my iTunes account to access to my purchase history of my purchased apps.
After logging in using my iTunes account, I have received an e-mail from Apple that my account maybe used by third-party user/apps.
I believe Apple does not allow other service to use iTunes account for login credential.
Is this service using illegal or near illegal method to access to my purchase history of my apps? Or does Apple provide an official API to access to its users purchase history?
I checked, but Apple doesn't seem to provide purchase history API.
This story just adds another data point to my growing belief that I want to minimize or ideally eliminate any further signing of contracts, forms, applications or other legal paperwork. "The big print giveth but the fine print taketh away." Every document you sign has the potential to become a minefield to be exploited by lawyers or unscrupulous types. Minimize your exposure to that as much as possible.
The part that should scare you the most is the arbitration clause. NEVER sign a contract with an arbitration clause, ESPECIALLY if you are an individual and the counterparty is a large corporation. Arbitrators are corporate puppets, and an arbitration clause is essentially a license to screw you in whatever way they want. I learned this lesson first hand the hard way.

"trying to get sites to render pixel-perfect across various versions of various browsers" - That is a big part of the problem. Now, I have designs I have to get pixel-perfect, so I feel their pain, but when developing your own app, you can opt to not go for pixel-perfection.

I don't believe their statistics, but their target market is much more likely to have multiple browsers and is probably willing to jump into a different browser if IE isn't supported.

But I think it is a dumb move to block IE9+. There is no good reason for it. They didn't give one in their blog post, and I have yet to run into a situation where if I am using web standards that I had many issues with IE9. Nothing I've had to hack around enough that I would want to block it. Seems like either an anti-Microsoft for the sake of being anti-Microsoft or just front-end devs not worth their salt (cause a front-end dev worth their salt wouldn't use user-agent detection to block IE in the first place, they'd use feature detection at least.)
Not directly -- I never had the pleasure of using NeXTSTEP. To be honest, this idea has been in my head for a long time, just waiting for me to come up with a proper interaction modality. I'm my own app's #1 user. :)
Basically, however when moving files you can't cut then paste. You can only copy/paste/delete. This is pretty intuitive and can be controlled very easily from the trackpad.
