skysight-inc/HackerNews huggingface dataset:
Depending on at which point these transactions are started and committed and the isolation level of the transaction this would either result in {"a": 1, "b", 22}, failure at step 3, failure at step 4 or failure when one of the transactions is committed. However, since locks are on row level rather than on value (cell) level, this would be the same even if these values were stored separately in ordinary column types.

You could still achieve what you want by using read committed transaction isolation and keeping your values in separate rows, e.g. a row with a/1 and a second row with b/2. But basically you would need a separate record for every property in your object graph that you want this behaviour to apply to, which could get pretty messy. Does that make sense to you?
I wonder what the list would look like if they factored in the value of benefits.
Both Google and Apple have reached this stage at around the same time in my opinion - both are now milking existing users rather than looking for innovative new markets or products. Once companies grow to a certain size it seems almost inevitable.
What about the bots that are not identifying themselves as such?
Right now the "defaulting to original is always OK" rule is encouraging attentional abuse [...]

Quite so, not least among publishers for whom HN is a major source of traffic (various news sources that focus heavily on SV and startups).

BTW, the twitter account @HuffPoSpoilers is a thing of beauty [...] It Is The Future.

Agreed, and thanks for drawing this to my attention. I need bots that do this sort of semantic analysis automatically for everything.
Hopefully it will reduce the cost, albeit slightly.

> Shareholders don't have voting rights, how can they pressure Google to do anything?

Shareholders do have voting rights at present. The problem is that Google Class B shares carry 10x the voting rights of Class A shares. Thus, even an overwhelming majority of market cap would still be unable to outvote the insiders.

Google is in the process of introducing a nonvoting C share class. This innovation was passed despite a mere 12% support among Google's Class A shares, because the insiders voted all of their Class B shares in favor. From now on, new shares created through stock options will no longer dilute insider control of the company.
It's a cat scan.
I think you are answering a different question. He's asking if you can update part of a json column.
Isn't that crazy? You can't write a generic integer array sort routine!

YC is slowly drifting away from its original mission.

I think that they tend to fund people who they think will have the highest chance of success. You end up with priorities like:

1. Previous successes

2. Company with traction

3. Employee at Stripe/Google/Apple/etc

4. Smart MIT/Harvard/Stanford student

5. Misc. high magnitude achievements

I think what you're seeing might be a higher number of 1-3 applying to YC, not leaving much room for 4 and 5. The four and fives who do get accepted are extraordinarily impressive.
Apple recalls last year's MacBook Air due to faulty SSDs
I never liked Pascal verbosity back in school but I loved C right away... Maybe it is just a matter of taste?
Yes, and the broadcast companies don't pay a cent of rent. Why are the public airwaves given free to private corporations?

Why shouldn't, for example, CBS be charged a modest $1,000,000,000/year for their use of the public airwaves?
Thanks! I'll have to take the original poster's word for it I guess :)
I think it's often a reasonable assumption for YC to make.

It would be interesting to see a break-down of school + degree for all successful YC applicants, though. Not sure if that's ever been listed anywhere.
That website has only 1 post. And the post is talking about "SEO" and the various search-engine names... In relation to a SEO business.

I kind of see what he is really trying to do...

Get Google to rank it from the start on long tails of "SEO <name-of-crawler> + other-keyword(s)".

(*I'm not complaining, it's pretty smart to start out like that, and make it on HN's front-page)
Yeah, self driving cars, google glass, and loon are not innovative new markets at all.
Choice quotes from Startup School 2012
Especially if you wanted to do a simple covered-call, e.g:

* Buy 100 GOOG at $1000.
* Sell 1 Nov 16 $1050 Call.

(Edit: Then assuming GOOG doesn't go down significantly it's a profit even if assigned)

Normally that would be a relatively low risk position, but you'd need $100,000 in GOOG underlying to cover it, which is a rather large amount for small investors to throw around even with margin accounts. And that's just for ONE option.

Edit: Oh, and if you thought $1000 is annoying to trade, check out Berkshire Hathaway:

A lot of the value of "more transparency" just comes from "if the title is changed, make certain the old title is also visible from the comments page, so people don't freak out". One time someone submitted a link to a YouTube video of a panel discussion involving Linus Torvalds where he explicitly gave NVIDIA both the finger and the F-word. The link was a link directly to the paragraph in the video where it happened, and the title was clear that that is what was being linked.

Upvoted to the front page, holding there for hours, people were having a discussion about the appropriateness of swearing in this context, the extent to which it was a joke, and about how NVIDIA has treated the Linux community. And, of course, then the title changed: it got reverted to something like "Random Panel from Random Conference".

Now, everyone was really confused: the comments were all concentrating on this one moment in an hour long video (linked to semi-directly, but still like 30 seconds after the link), and freaking out about how people were so uptight and shouldn't be concentrating on that, and that there was all of this other content there.

When the title changes, it drastically changes the character of the discussion: while this website is also a link aggregator, I know of very few people who believe that that is its value; instead, people like Hacker News because of the comments: it is a discussion forum. You can't just change the title of the discussion forum while people are actively discussing things without causing a catastrophic situation.

This is thereby what I mean by "transparency": I don't mean a moderator spending even an extra 30 seconds explaining "why" something happened... I just mean that the site needs to make it clear that something did happen, or these massive arguments break out and a bunch of people are left unhappy and angry. As long as title changes are going to happen to discussion threads that already have hundreds of comments, you at least need to have a boolean "title changed" notice.

That aside, the "nuance" aspect (which I think is even more important than the "transparency" part, as you might just decide "old posts should never have their title changed" and the transparency is less important) would probably require more time from the moderators. I am not certain how to get around that: I think moderation fundamentally requires nuance.
I don't trust some dude on the Internet telling me "that's negligible", or "I totally notice the difference".

I want to see a study done to determine how "worthless" it is...
What about allowing up/down voted on titles (turning downvote rights on for everybody). If the title collects too many downvotes in relation to upvotes then the submitter collects negative karma and the moderators are notified about bad title.
That would be less work for moderators and pointless changes would be reduced as well.
It looks like I just squeezed in - I bought this machine in July 2012, but it's the older model without USB 3.
Thanks for that. I do hope you're right. The prospect of eternal isolation is not a pretty one.
Me neither! It should be possible to build hugely different levels with it, kind of like the StarCraft II map editor (which lets you build first-person shooters, underground, or like 2D sidescroller arcade games.)

I really want to get it so that people can create campaigns for younger students, or for advanced developers.
Those are all research projects at best, you can't buy any of them and you're not likely to be able to anytime soon.
Turbo Pascal Compiler in JS
It took some hustle but we made it happen. If you can dream it you can do it! Here's to the next big thing.
"because they’re not allowed to mess up we’ve created a system where it’s also very hard for them to do things that are new and innovative. The rules all favor incumbents."

So true. From this article:http://www.infoworld.com/t/e-government/how-federal-cronies-...
_______________________________

"All but one of of the 47 contractors who won contracts to carry out work on the Affordable Care Act worked for the government prior to its passage," the report reads. Some of the names ought to be familiar: Northrop Grumman, General Dynamics, Deloitte, and Booz Allen Hamilton, all of whom assumed different roles and worked on different aspects of the project.

As familiar as those names might be, especially to those who follow Beltway lobbying practices, few of them would be as commonly associated with large-scale IT projects as, say, Google, Amazon.com, or Dell would be -- especially when it came to building the public-facing components of the system. (Techdirt concurs.)

Why did they get the work? The report hints at a likely reason: The companies were big lobbyists, with "some 17 contract winners reported spending more than $128 million on lobbying in 2011 and 2012." Granted, some experience with government work is vital for any contractor, and the federal procurement system is geared to favor those already doing government work, but Sunlight pointed out that the list tips heavily toward those with both existing contracts and political leverage."
_______________________________

Unfortunately the US government procurement system is set up to reinforce cronyism. There are a lot of mechanisms in place to try to prevent it, but the way proposals are structured, it's very tough on new entrants. The factors of a typical US Government IT proposal are Past performance, Key personnel, Technical, Management, and Price. Sometimes these factors are blended or worded differently but in nearly all cases, the technical approach can become a small portion of the overall decision. This favors incumbants with some track record (and perhaps some ex-government employees that are still buddies with some of the key players) over ones with no government experience, even if it's not great like CGI Federal.

Adding more issues, procurement officials are under a ton of time pressure and often don't have the skills to understand that the relevant most past performance qualification in the development of a health exchange is not simply having worked on previous contracts in the government health space.
I'm often asked for recommendations on how to learn to program and this will probably be perfect for nerdier types (but looks like it assumes zero initial knowledge, which is awesome). What other things do folks recommend? Coursera? Code School? Khan Academy?
I had heard people say this about Reagan. He took accountability for things that were arguably out of his control, and people later didn't blame him for things that were.

To me the lesson is accepting blame for a problem doesn't just take "Whose fault is this?" off of the table, but it increases the trust in finding a solution.

FNSAIPS: Make Your Data Vanish If Viewed By The NSA
I'm not in any way affiliated with Google but a Google employee has strongly and empathetically suggested to me that the ad people (and algorithms) have absolutely no access to user account data.

That is the reason why AdWords location targeting is kinda broken currently (at least on non-mobile devices it relies on IP geolocation). If one day AdWords start serving geographically correct ads for everyone, that's the day when the ad people got access to account data.
Awesome, that's exactly what I was hoping.
I started with adWords and then quickly got into the first page for organic. It doesn't matter, I still get negligible organic traffic, it's almost all paid. Seems like consumers have been trained to go to adwords results when they're looking for a service or good they want to pay for, and organic when searching pure information (free).
This makes a lot of sense to me - it's not even because the apology is logical, but because it's a gesture that shows the speaker is thinking of the other's welfare.

There's a rule I have followed for many years when doing customer service - if the person is upset, apologize. It doesn't matter if you can't give them what they're asking for, or if they made a silly mistake. Just - make them feel better, then do what you sensibly can. It really works well... I don't get many angry complaints anyway, but this tends to defuse them immediately.

Shouldn't the control group have had a non-apology comment about the weather or something? Instead of comparing, "Sorry for the weather. May I use your phone?" to "May I use your phone?", it would seem much preferable to compare it to "Lousy weather we've been having. May I use your phone?"
Did you mean 14.10 would have XOrg, or am I reading this way wrong?
I'm pretty sure sometime shortly after buying this machine I was able to install a "firmware update" from a USB-booted OS X install, but don't quote me on that :)

I'm somewhat unfamiliar with Apple's software generally (I have always just run Debian) - do they release firmware updates often? What kind of things do they fix?

Exactly right. Turbo Pascal compiled straight to machine language, which made it hard for them to do nice optimizations. But people like me didn't care. IBM's compiler couldn't blow off optimizations, though. Typical worse-is-better.

This compiler started out as a five-pass compiler, then I reduced it to two. I could have reduced it to one and simplified the code quite a bit, but having the intermediate parse tree made debugging easier. The parse and compile passes together take less than 20ms on the largest Pascal program I have (rose.pas).
I performed your experiment and it didn't seem to match your conclusions.

My search was: jwt web toolkit

The search page itself had no Google ads on it.

The top link was the homepage for the toolkit project. There were no ad links on the page.

The second and third links were for wikipedia, which contained no Google ads.

The fourth link did have Google ads on it. The fifth and sixth lengths did not. The seventh link did.

I tried again with a different set of search terms: neutron spin echo

The top of the page did contain a link to Google Scholar, followed by three links to pay walled articles. I am not aware of any profit agreement between Google and the publishers, but it wouldn't surprise me to learn that it's there.

The remaining links were either to pages containing no advertising (Google or otherwise) or to more pay walled articles. Short of Google have a relationship with the publishers, Google again made no money on this search.

For the record, I don't have an ad-blocker turned on, so I would see ads if they were there.

tl;dr - a flawed study concluded something that may not necessarily be true
I'm not going to lie--I think buying any device running 2.3 at this point is a giant waste of money, comparable to buying a laptop with Windows XP on it. There is no reason. Nexus 4s are recently out of stock at $200, and the Nexus 5 will probably compete in that area too.

It's a shame that republic wireless is handing out 2.3 devices--that really should stop.
I'll grant that maybe the immersiveness will somehow lead to useful applications. The therapeautic example given by arrrgh above, for instance. I still don't see good examples of general applications, but I'm probably coming across as moving the goal posts and I don't want to be an unhelpful stick in the mud so I think I'm going to resign the thread shortly. But I have greatly appreciated the replies I've gotten.

I don't think immersiveness is necessarily a desirable property in entertainment. Movies, for instance, seem to be less immersive when they're more realistic (the Hobbit movie, for instance). There is something eerie about daytime soaps that arises partly out of their higher framerate. McLuhan did say something to the effect of movies being a "cool" media, meaning you could be absorbed into them. This characteristic seems to be inverse to higher detail. If I were to make a bald-faced guess, I would mumble something about higher sensory refinement taking processing away from appreciating the other aspects of the art. I don't think it's impossible that the fidelity we have today for film is essentially perfect as far as our perception and enjoyment goes--that is, after all, the case for music. This might sound like a controversial opinion here, amongst people who have inherent appreciation for the technical, but amongst our families I bet it will sound more plausible.

Anyway, thanks.

That's exactly what I thought when I read the article. I'm not quite sure how that was missed during the design of the experiment.
It includes no link to normative documentation, for one, but this isn't one of the most egregious examples of w3schools sitting at the top of search results when it provides absolutely terrible (either wrong, or completely useless) information.

A better example is: "html iframe element". Go ahead and look. What's more interesting here is that if you modify this query to "html iframe element scripting" the top 3 results are now w3schools, one related to the <script> tag, while the relevant section header in MDN on scripting isn't even highlighted in the matching result from MDN. The word "scripting" does not even appear in the rendered DOM of the w3schools page for <iframe>.

At this point, it's pretty safe to say that there's a reason, distinct from content quality, why w3schools is always promoted over better sources of information. Popularity doesn't seem likely either (http://www.alexa.com/siteinfo/mozilla.org vs http://www.alexa.com/siteinfo/w3schools.com). The site is:

1. Covered in questionable and low quality ads.

2. Intentionally misleading in general but especially in name (w3schools is not affiliated with the W3C or any standards body).

3. Abusing its position (in both search rank and in its misleading name) to sell useless "certifications" that not one company in existence would take seriously.

Why doesn't Google consider this a scam and factor that into its search ranking?
People hate that and often call it a link-bait or the top comment ends being "Link to the Original".

But then the top comment on such submissions end up being [Original]: <link>

So it just might work.
I think the question is how does that compare to the usual trick of adding a key/value/attribute table?

create table misc_attrs (maintable_id foreign key, name text, value text)
I once interviewed a guy whose resume implied he played a large part in designing some of these redundant systems for carriers/whatever.

I asked him how he dealt with failover/etc, and said they used master election, and that it was guaranteed to work, and then proceeded to describe exactly a system guaranteed to fail. He had never heard of paxos, and when i described it to him, he was sure it wouldn't work.
That was a good read, congratulations. Would you mind answering how you plan to work, or will you compete with, private ACH networks like these folks:
