There are several levels at play here.

malloc maintains a shared data structure that is used across cpus and must lock for access to that data structure. There are optimizations there being used with some alternative allocators such as per-cpu or per-thread pool but these only reduce the rate of locks taken.

In addition after you have that virtual memory in hand you need to have physical memory behind it which entails a page fault which switches into the kernel to get you a physical page, this happens per-page.

There is also the effect of physical memory layout on performance, if your memory is perfectly contiguous and your data is laid-out properly you can reap benefits from that compared to the quite likely fragmented nature of data in a heap-allocated setting.

This obviously means that the applications needs to manage its memory allocations on its own but when you really care about performance these become important concepts and I too tend to write my libraries for such reuse and avoid memory allocations inside them where possible.

malloc is a general purpose tool and as such needs to cater to many different environments, including multi-threaded programs so it has to lock its access to the shared data structures it holds to main

If there ever comes a day when I actually use yahoo, I may just take your advice and look for that. ;-)
I prefer hearing about _the reasons_ why something new is not appreciated rather than the usual "the older was better".

The poster of the complaint didn't really want to go back to the old My Yahoo. What they want is a new My Yahoo that

* use smaller fonts ("Font way too big and no way to adjust.")

* preserve the user-configured layouts ("Apps are rearranged all over the place, and some old ones are no longer available.")

* provide the useful quick previews for new items ("Hovering over news items no longer gives brief synopses.")

* etc.

Any discussion about "new vs old" is not going to be constructive. Users should learn to report "what" they want, not just filing generic complains. But treating users as intelligent people that can be taught things may go against the current trend of treating users (especially when customers) as spoiled kids.

If I were to deploy such an interface change I would provide a complaints box with these instructions: "0) complain only about one things, you can file as many complaint as you want. 1) Please summarize what you do not like. 2) Please suggest a better alternative. NOTE: generic complains like 'it sucks' will be ignored."

I had the latter happen to me and so have several other people here on HN. LinkedIn ended up sending an invite to everyone I had ever emailed. It was catastrophically embarrassing and caused a lot of grief.
What a pathetically inept Web site. If you go to http://www.sbs.com.au/dateline/story/about/id/601007/n/China... and click on "watch his latest story", you don't watch anything. It just goes to another page with another list of links (possibly most of the same ones).

Not misleading and fairly standard practice. There is no value starting at 0 when the lowest device tested is 55, all you'd do is shift everything to the right or make it smaller and harder to see the distribution (which is the whole point showing the distribution from 55 to 123).

As long as the graph goes up in consistent increments (in this case 10) and shows that all these devices could move to the left (i.e. get quicker than 55) I'd say the graph has done its job.
What is surprising (and scary) to me is that corporates such as Yahoo who have lots of money and great talent can only end up with seriously mediocre at best re-designs?

At first reading the user complaints, I just thought "Bah, they would get used to it" (without actually visiting the page first). And then I visited https://my.yahoo.com, I totally agree with those complaints. as a fellow designer, some points I've noticed:

#Poor selection of font sizes

#Poor selection of colors (especially for background)

#Poor application of borders (remember, in design, borders portray complexity (in this case, unwanted).

#Inconsistent design themes (Search button has borders and gradients and shadows, the rest do not)

http://img809.imageshack.us/img809/9383/hhew.png

It seems to me that the design they had in mind was something iOS7-ish (which is actually good due to the minimal information it shows the user at any point) , but ultimately they ended up with something else more complex, confusing and awful.

Either way I wish Yahoo good luck and wouldn't dare to judge an entire company based on this design alone.

The Customers filing suit should know that LinkedIn is a publicly traded company and not a scam site.

Did you mean to say that? I know nothing about the details of this lawsuit, but I hope you realize that being a publicly traded company is no proof of being virtuous in all one's business operations!
True. When I was actually in high school I had a harder time realizing that, but I recognize that sports aren't inherently bad, it's the way some of the sports are elevated above all else.
Some LinkedIn apps ask for pretty extensive permissions:
https://news.ycombinator.com/item?id=6014842
There's that, but what I meant was they could combine the user's LinkedIn password with their email address and most of the time that would be a valid user/pass combination due to the frequency of password reuse. It's not like LinkedIn don't have access to the plaintext version of the user's password. After all, the hashing isn't done on the client but on the server.

This is the reason why I changed my Android for an iPhone.
LinkedIn provided a pop-up window which, in small print, if you had logged in via Google or Facebook, notified users in legal terms that their e-mail contacts could (potentially, under some circumstances) be accessed.

Thus, in legal proceedings, the user was entirely informed of the possibility of this situation arising.

For future users, this sets a precedent that users are aware of the terms and conditions (as they have always been), and no further accidental leaks of personal information will occur.
Same here. My 21UX is staggeringly more responsive, and I expect the newer ones are better still.

He almost always does short statements often of a slightly ambiguous nature. This helps him avoid having to say he's wrong in the future.

His sterling analysis (i.e. complete failure to see it'd be a success) of the Galaxy Note monster phones is a fine example of this.
Here's how they do it. Various times Linkedin provides me with a form to "import" my contacts from my gmail account.

This dialog looks very similar to the login form to the site. If you use the same password for both sites (I don't), you might be thinking that you're logging in, when in fact you're bringing in everyone in your address book. Not sure, if they then automatically spam everyone on your list or not.

Linkedin clearly has crossed over to the dark side since they went public. They keep reducing their free services and pushing harder and harder to try to get you to sign up for "premium" accounts. It's time for an alternative.
and sports. top center for each team page used to be the most current game with direct links to box-score and recap/preview. below that was news with stats and division standings in a sidebar. everything I wanted on one page. Now it's split into multiple pages that aren't well interlinked.

>ChatRoulette and Omegle require you to actively participate.

Absolutely -- they're not direct replacements. The problem is that a lot of what made Stickam fun is the size of its audience, and the demand for a Stickam-like site is much lower now that ChatRoulette and Omegle exist. So there probably won't be a Stickam-like site that's as fun as Stickam was.

So on the money. How does this happen? Mayer's majdate was all about a culture shift, aligning the company to her old digs at Google. But it remains a thoroughly mediocre interface and service (for some reason I have refused to relinquish my Yahoo Mail account).

I think it comes down to 2 things:

A) there's an AOL-esque aspect to Yahoo. I genuinely believe that they don't want to be innovative, because they have such a white-shoe and casual-user demographic trapped in their walled garden. Yahoo doesn't want or need to re-invent ghe wheel.

Ii) Yahoo, as s company, is such a bloated entity. A fresh, interesting, original design concept would have so many layers to penetrate. Hence, the diluted mediocre crap.

Where is the phrase "identity fraud" agreed to? That is more the line that seems up for debate. Also, LinkedIn forces changes onto otherwise grandfathered accounts (LFN). If you don't actively delete your page, you agree to whatever the worst case is under new terms.

Would I, with my naked senses (eyes, touch) be able to tell the difference between a 55ms response time and 117ms response time? Alternatively, does such a difference add up or combine with other factors that ultimately make it noticeable to me? How? And while we're still at it, is this winning performance by Apple touchscreens a function of the quality of the screen itself (or components), other hardware (ICs and what nots) that work with the screen and are a factor in how it responds, superior code at OS level? I'd love to hear such details, as opposed to merely telling me 55ms vs 120ms.

That's brazen, but if the plaintiffs complied with that prompt then they're basically telling the World that they not only violated the TOS of their e-mail provider but also their terms of employment and common sense.

The casual dismissal of their sincerity is annoying ("don't know if they're telling the truth, or just saying government-friendly things because the governmental people are here right now!"). At least do the due research if such claims are going to be made by trying to get interviews from these folks without governmental people's presence, or just don't doubt their sincerity. But please don't just sprinkle in the there's-no-freedom-in-China FUD willy-nilly that we've all heard enough of already. This is like how when the hacker faction of PLA is talked about there's an ominous music in the background and serious faces of reporters looking at you to set the tone of the piece as if China is this mysterious and strange entity that is going to bring us down, all the while America's Olymic Games programs hardly even ever get a mention.

Anyway, I think we might be looking too hard for large problems where there might not be any. Don't forget that we have a similarly ridiculous situation in America: for every homeless person there are 26 houses that are vacant. Considering that China's population is a 1.35 billion (about a billion more than America's), at least in one respect it would seem like a prudent choice to build high-rises in place of crudely-made one or two-storey building houses in anticipation of future housing issues.
I thought restaurants make more money from drinks (and deserts) than actual meals.
Here's what may have happened: when you go to LinkedIn, you regularly get shown a box (inline) inviting you to do something, like endorse people's skills.

One of those boxes invites you to "grow your network". It's not all that explicit as a call-to-action, as in the text may just be a slogan. The main focal point of that box is a login & password form, which looks exactly like the regular login form that users get when they want to do something that requires explicit re-authentication.

In other words: it's common to have to enter your login/password on LinkedIn, this looks a bit like one of those cases, so users will blindly start typing. If they use the same email/password combo for their email account as for their LinkedIn account, then they've just given LinkedIn access to that email-account.

The box itself is quite deliberately misleading. Unlike the regular invitations to load your addressbook, there are no Google or Yahoo logo's, and no explicit descriptions.

I don't know whether there is a more explicit request for permission at the next step before it starts sucking in conctacts, I don't dare entering a valid password.

If there is a next step that requires explicit confirmation, than this "trap" (which it quite obviously is) is merely annoying and a bit scummy.

If there isn't, I think they have a good case, because this is would basically be phishing in reverse.
I'd really like to live in a world where serving your local community, as these restaurants clearly were, is more important than maximizing profits to the detriment of your community.

I'd say designing user experiences so it no longer feels like you are using a computer is one of the most important problems in technology today. Doing so alters the way the mind and brain deal with feedback and completely changes the way users end up using a tool.

I had the same experience... I visited Montreal last month for a business trip, first time in a couple of years, and had 40 minutes of rather hostile questioning on my way in.

It didn't make much sense to me, and I assumed that they'd picked a middle-aged, grey-haired, white guy so that they couldn't be accused of racial profiling... but from comments here it seems it is a lot more general.

Some of the questions didn't make a lot of sense (especially not at gone midnight), one or two were personally rather insulting, and they seemed to think that I was over here for employment rather than business meetings.

Getting into China the following week, on the other hand, was a model of efficienty and politeness...

The W39 is a revision of the Mark 15.

According to Wikipedia, the Mark 15 had a real thermonuclear second stage that generated significant yield. However, its second stage was also packed with enriched uranium, and it obtained most of its energy from fission.

Essentially, it was a two-stage thermonuclear weapon that had a lower fusion fraction than most two-stage weaopns.

Summary of atomic weapons:

1. Pure fission. Fusion contributes 0% of yield.

2. Boosted fission: Fusion is used solely to improve the explosive yield of the fission. Fusion contributes 1% of yield.

3. Dirty two-stage thermonuclear: Fusion contributes between 1 and 50% of yield. Most of the yield comes from fissioning of the U-238 tamper by fast neutrons.

4. Clean two-stage thermonuclear: Fusion contributes 90-99% of yield. The U-238 tamper is replaced with beryllium or lead, which does not undergo fission when hit with fast neutrons.

5. Three-stage thermonuclear: Same as two-stage. Thermonuclear bombs are considered to be an "unlimited" design, because you can keep stacking stages on top of each other, until you've got enough to blow up the planet.
