You have to realize, previously, when a page was "liked" that was equivalent to WANTING to see updates from this Facebook page. That simple like was a 2-way contract, you're interested in us, when we post, you will be aware of it. Now the "liker" could be missing out on items they find important, and the fan page is effectively impotent in reaching that fan unless they pay to promote the post.

It really is a bait and switch and I'm surprised there isn't MORE outrage about it.
Using ECC would solve this particular problem, because in both DKIM and DNSSEC usage of key lengths of 512 to 768 bits and not more are motivated by what can fit into one UDP DNS reply packet. Also for RSA signature size is equal to key length, and not some small multiple of security parameter and you don't want to expand messages by including large signature that might well be larger than actual payload.

You really think we're at that point? I'd be hard pressed to name a single thing I've bought that I discovered from a Facebook marketing effort. I'm currently drawing a blank, off the top of my head. I find local restaurants by walking/driving around or searching Google. I find out about products and the like from TV ads or just seeing them in stores.

I've got friend who "like" companies on Facebook to get discounts and such, but when I've talked to them that's been pretty much the full extent of the interaction—basically a new-style email list that gives them occasional discounts. But is that essential to the survival of most businesses? I'm on FB to connect with my friends, I simply would never even consider "liking" 90% of the companies/products I buy. I don't need constant updates from the company that makes my tires, or my jacket, or the vast majority of mundane stuff that makes up the world.

The first company that comes to mind when I think of recently successful marketing is Apple, and do they use social media marketing at all? They seem very old school, with traditional TV spots and billboards that show you the product and what you'd use it for.
Wait, this is a big deal if swipe is being phased out. Very few us cards have a chip. That will make it impossible for US tourists to use cards in Canada.

He spent weeks trying to get help from them, to no avail. It's more than reasonable for him to post a negative review at this point, explaining the situation, taking blame where he should, and warning others to think twice.

All I want to see from the CEO in a situation like this is: "I'm sorry. We fucked up. Here's how we'll make it right, and here's how we'll make sure it doesn't happen again."

And if you genuinely can't say that because you don't think the customer is right and you're not willing to do anything for them, just keep your mouth shut.

To clarify slightly: Starting in 2015, if your card has a chip, the bank/credit card company will blanket reject all transactions authenticated by swipe. If you have a card from a Canadian institution, it will be replaced by one with both a chip and magnetic strip by that time (and it probably was years ago already).

If your card only has swipe (like US tourists), presumably their institutions will still accept a swipe as valid authentication.

That depends on what you are cooking I think. Most things I am normally inclined to cook require me to attend to them while they are cooking. Slow-cookers eliminate that and do other things instead, like go to work.

Even if you are cooking something relatively hands off in your oven.. how often do you leave your home while your oven is on? You are locked down to that location for the duration of the cooking time.

As soon as someone uses an affiliate link, I become wary of their motives. Are they really linking to this service because they use it themselves, or are they linking because they offer higher kickbacks than their competitors?

I think somewhere between 10 and 12 is the sweet spot right now. Also, just to be clear, 08 is a little more than "less than half". The work factors are exponential. Half of 19 would be 18.
I object to Facebook making this decision for me. I _didn't_ add too many friends. My newsfeed _wasn't_ overrun. Yeah, I had to hide a few annoying Apps, but no big deal.

And then, one day, I stopped seeing posts from lots of people, including many of the people I most wanted to see posts from. It took a while before I even realized this was happening. Then I slowly had to go through and fix the settings for people to tell FB that "yes, really, show me all the posts". And, still, every couple of days Facebook forgets that I've set my sort to "Most Recent" and goes back to "Top Stories" and not showing me everything. This gets tiresome, to say the least.

Right. Either expanding the key length or using ECC would fix it. So saying the problem isn't one of those, but is only the other, doesn't make much sense to me.

ECC may even be a better solution, as you say, but that doesn't mean that the problem isn't also one of an insufficiently long key.
> Arguing anything other than differences in levels of exercise/activity and calorie intake has a large mountain of evidence to overcome. The effects of those two are very large, the effects of everything else comparatively small per decades of animal and longitudinal human studies.

You may have read a different article. As this article noted before even the first of so many page breaks:

"And in Loma Linda, Calif., we identified a population of Seventh-day Adventists in which most of the adherents’ life expectancy exceeded the American average by about a decade."

A full decade, within the same American safety net, is a tremendous difference. Born SDA myself, I can tell you that Loma Linda is not a hotbed of exercise and caloric restriction. (And the benefits are not localized to Loma Linda; the researchers hit upon SDAs there because the concentration in Loma Linda was high enough to show up on zip based data).

You say that anything other than these two makes a difference takes a mountain of evidence to overcome, well, we have that evidence. SDAs are generally just as sedentary and eat just as much as the average non SDA next door.

What SDAs in Loma Linda do differently: don't drink, don't smoke, take 24 hours away from stress each week, and to a large extent, avoid meat with an otherwise normal diet of grains, legumes, vegetables, fruits, and dairy.

While it's awesome that the good folks at Pagely were able to work with you a little to try to address your problem, like most PaaS providers (eg AWS, Heroku) we don't provide consultancy services - there is an amazing WordPress community of consultants and dev shops out there and its just not what we want to get into

Which is fine, but then you website says this:

- http://wpengine.com/wordpress-experts/

Not so at WP Engine. Our staff consists entirely of WordPress experts, so we can help you track down and troubleshoot WordPress issues.

Which is totally misleading, and exactly opposite of what you say. I wouldn't blame the customer for dissing.

Convenient that this is also a windfall for Facebook - you know, it's for OUR benefit.

Consider why Facebook doesn't have a "more" button for users tired of staring at the same Facebook filtered posts. Because that would be giving users what the want without charging anyone. (Even the recent posts sort - a hidden option - doesn't seem to work anymore)

This is extortion and anti-user. No bones about it. Users requested this information in their feed and it would be trivial to give it to them. It's fine to filter, but not fine to not allow unfiltering.

The typical customer support process is bad for the complicated edge cases, which sometimes end up in threads like these. But it's good for business. You don't want your engineers attending to one person's problem. That's called consulting. You want them building product. Building perfect software is bad from a business point of view. In WPEngine's case, the takeaway from all this is to add a line to the customer requirements list on their website (useful for filtering out the undesirable bottom 5% of customers) that says they will not accept any of the few potential customers that use the native WP commenting system because it's poorly built.

I'm not sure if it's true, but based on the poster's description of WPEngine's customer support experience, it sounds like their customer service is the typical poorly structured (from the customer's point of view) customer service experience I've encountered and/or witnessed many times from companies both large and small.

Some startups don't provide phone support. It's nice to see WPEngine does. Sometimes you just have to talk with someone to beat it into their heads that you have a complicated problem. They can't email email you back a link to some topic-related doc page and move on. They're on the phone with you and they have to make meaningful progress before hanging up.

In the case of email support, 95% of the tickets are answered with a link to a doc page and that's the end of the case. The metrics are excellent and every pats themselves on the back. 95%! And the volume was soooo high! Acknowledging positives is necessary, but measuring failure requires different metrics and 95% success does not necessarily imply 5% failure because each one uses different metrics. You think the the metrics on their dashboard will take into account this thread, for example?

The system breaks down when the customer has a more serious problem. It takes support a few emails back and forth to realize it. The case is handled by random folks based on availability, further degrading the experience. The person who'll pick up your latest reply to the thread isn't going to thoroughly read the whole thread, and by this point you've interacted with five support staff already. Finally, they realize it's outside their control and pass it off to Engineering, where it languishes for a month. Creating a system where the engineer is not allowed to reply directly to the customer but instead has to reply to support who then replies to the customer only removes the stress off the engineer, so they can care less and not solve the problem. Meanwhile, the support staff learn to drop lines like "Sorry for the delay. We appreciate your patience. The engineers are still looking into it." without any second thoughts.

Wouldn't that require real AI though? I thought for a minute that NLP (Natural Language Processing, not the other meaning(s) of the acronym) might help, but then thought that it may not work for cases where the comment is quoting another comment. Note: I'm not at all an expert in any of those fields, just interested.

Facebook has enough data to know how close you are to people, and there's even a "Close Friends" list you can add people to in order to see all of their posts. Your friends who want to see your posts will see them. Those who are ambivalent might not, and you can pay to make it show up for them.
> Both Arrington and Siegler left TC because of their involvement in the CrunchFund and the obvious conflicts of interest that arise when you report on companies you invest in

Uhm. Mike wrote about companies he had interest in in TC from the very beginning, with various levels of attention to disclaimers about it.

AOL as the corporate parent in TC is an investor in CrunchFund, so it's not like Mike and Sieglers absence from TC has somehow meant that AOL hasn't had an interest in TC writing favorably about the same companies as the two of them either.

I don't see how this actually materially changes anything. You're free to dislike that. They're free to write. You don't need to pay attention to the,.
Jimmy Wales will be voting write-in for Jimmy Wales. It's his world, you know.
What the post says makes sense if you assume that it's an entirely cosmetic change, which it's not.

YMMV on the styles (I'm undecided on them), but there's a ton of stuff under the hood that just couldn't be slapped into the desktop, without huge drawbacks or compromises. In the second section the post kind of recognizes this saying they're doing it because "the world is going mobile"/low power, but then immediately goes on with "It's change simply for the sake of change", and I don't think it can be both. Simple squares, non-overlapping windows and text rather than (pixel shader'd) graphics aren't just an aesthetic thing, there's a fair amount of practicality in there.
Is water used by hydroponics really "used"? As far as I can tell, aside from "loss" to evaporation and water used in part of the mass that makes up the fruit you send out, nothing should really be wasting water.

It seems likely that lost water due to evaporation with this type of setup should be a great deal less than water lost with traditional farming (spraying water with things like center-pivot irrigation machines should cause much more evaporation. I mean, come on... http://upload.wikimedia.org/wikipedia/commons/6/6e/Irrigatio...), and water lost through fruit mass is irrelevant.
At Rackspace, we use Node.JS and Python out of those.
The whole premise of this article is "Facebook gave me this access to their platform for free hitherto, so I'm entitled to this access on those same terms in perpetuity; it's unfair for them to start charging for it." I don't see the author explaini why s/he is entitled to these same terms forever.

Still, it would be very hard to make sure that the provided code is indeed the one running on the suspicious machines. The only way I see to make sure of that would be to provide tools to compile and flash the hardware, which doesn't make much business sense. This also gives no protection to silicon based backdoors that has nothing to do with OS code.
Or try running an A/B test on it, and submit a blog post with the results to Hacker News!
Yeah but it's a little bit trickier than that. If Facebook does things that alienate users, then those products will walk off the shelf - and not into someone's shopping cart.

> The key issue is that this widget performs a query on the wp_comments table which becomes slower and slower as the number of comments rises..

I dont' see why a selective read based on primary key indexes is taking so long. How many rows are we talking about here ? I'm sure it's under a billion rows - right ? Partitioning it may help but I think there's something significantly wrong with the way the lookup is going through.

The recent comments widget is probably doing things the wrong way around. Is it caching the returned values ? Does it matter if the recent comments widget is based on data that is.. say 2 minutes old ?

I really don't agree with your performance bottlenecks. I run several sites much larger (at-least 20x traffic per day) and granted that they do not all run Wordpress, I know from experience that your system should not be grinding to a halt with just 50k daily uniques.

Even imagining that the comments lookup is like "get all comments for post ID, 2966 --" - that can't possibly be slow enough to destroy your entire server setup. Maybe you just need more RAM ?

Get a dedicated box and get someone to optimize it. If your entire database can be in RAM (Get a box with 16GB of RAM ?), that should work well. That won't cost you $250/month even.

EDIT: I see from another post:
As Sean, my head SysAdmin wrote on a ticket to you, some of your pages were performing a sort on 188590 rows in memory each time.

Was that the recent comments widget doing that ? Well, that can be fixed with some clever caching or even a clever fetch technique!

Is that necessary for every load ? Do you have a particular blog post with that many comments ? The right way to go about that would be to pick out comments for a particular post and then sort them - query-wise. Again, your WP install probably needs some (much needed) tuning.

I understand your desire to have someone else worry about your servers, but someone also (apparently) has to worry about your code, and as I understand right now - that person is you. Well, you could definitely make some code level improvements and save on the 'server management' department.
Impressive that Square can launch in Canada while much of Google's offerings apparently can't.

It'll be interesting to see how it works out for him. Gasketball, the new game by the two guys who made Solipskier, monetizes the same way. Selling Solipskier for $2.99 on the app store earned them a living for quite some time, but selling Gasketball as a $2.99 in-app purchase was so unsuccessful that it left them literally homeless[0].

Having Loren Brichter's name behind Letterpress will definitely help spur initial sales from the HN-type crowd that wants to support him and check out his latest post-Twitter project, but beyond that I'm interested to see if he finds success with this model.
