While I understand Twitter from a technical perspective, I have never understood why a large number of people use it. The value proposition for an average person is effectively zero. It's great for businesses and celebrities, but one-sided value propositions tend to not work out long term. We are now starting to see that inevitable result play out. You can only defy gravity for so long.
In other words, they missed earnings by 4.5% (comparing the means of the two ranges) when the original uncertainty range on their estimate was also 4.5%. Doesn't seem very exciting to me.
Social Stacking Technique: How to Grow Your Traffic with Social Media
Yep, same experience here (birthday cards as part of a larger app, which contains a viral component in it).

The added value of a FB login etc just dropped tremendously. And it's made devs wary of building on FB as you may get a notice that a year later your API permissions are getting revoked.

Did you ever find a solution to that by the way? I've had some ideas but they all require some manual actions. We're completely uninterested in the friends' data, we don't store it, it's only used for the individual user to allow him to perform an action at his own will (send a birthday card) and facilitate that. It's really too bad they clamped down on this one.

It seems it could have easily been solved by putting the friends' birthday permission behind an approval wall (which even the user birthday requires, you need to get your app approved by FB if you use it), and offering users (an already existing) the ability to turn off sharing of basic data with friends' apps. Especially when people have it on their public profile, if your data can be scraped publicly because the user makes it public, why restrict an API?

I'm one of those people that is very private about my data, but a lot of my users are 38 year old moms who share their date of birth (not necessarily year) with friends, and would love for them to send them a birthday card and couldn't care less if the day/month of their birth was somehow known to the world, while they're protected by a decent approval process and have the autonomy to turn off sharing.

As a developer, I feel they weren't as practical as they could have been here and there.
I think the writing is on the wall for Twitter. The younger generations are increasingly flocking to snapchat, yik yak, and similar apps. I never hear of anyone using it anymore(college student here). I would have stopped facebook a while back as well if I didn't use OAuth for damn near everything
In the attack described here: http://media.hacking-lab.com/scs3/scs3_pdf/SCS3_2011_Capkun....

the attacker has two devices communicating by radio. Device A is near the keyfob, and device B is near the car. Each is a repeater for the other: Whatever the car sends is picked up by device B and repeated by device A. Then the keyfob's response is picked up by device A and repeated by device B.

This type of setup will defeat both of your proposals. Triangulation won't detect anything out of the ordinary, because device B can be right next to the car. And the ultrasonic challenge/response can be defeated just like a radio challenge/response, using microphones and speakers on the repeaters.
Personally, I find Twitter highly overrated. At least 90% of this service seems to consist of inane nonsense, assorted trolls, blowhards and every *ism imaginable. While other services like Reddit (or HN) offer the community a way to curate content and block out the worst nonsense, Twitter buries you with it. The only way to use it is to only follow select people and stick to your news feed. But there the 140 character limit all to often makes it impossible to deliver anything more meaningful than a headline and a link.
Yeah, I'm at that weird spot where I need to do bulk actions often enough to be bothered by losing them, but not often enough to justify figuring the API out. Appreciate the reply though, definitely glad it's being looked at :)

Audio woo is always worth debunking, this is pretty good.

I wonder if Tidal will try to pivot to selling pure snake-oil 24/96.
I guess you could word that as "it means something if what you are the best at matters to you". If there is something that really matters to you, by all means do all you can to be the best in it. You will love every bit of it while you're trying (okay, not every bit, but you get my point), which will make you happy---for instance, I've never met a great musician who didn't look forward to and didn't love their practice sessions. And, as an added bonus, you might actually become the best, or really, really damn good. That must feel heavenly.

Australia has quite a high urbanization rate (89.2%):
http://en.wikipedia.org/wiki/Urbanization_by_country
"When you have a sedan/suv/minivan, traveling with kids is much more tolerable. You don't have to carry everything on your back or in your hands. You can strap them into car seats once and that's just about the only time you have to worry about it."

From 1st hand experience the main problem is finding a cheap parking spot near your destination. Then you still need the pram or the stroller to get from that spot to where you are going. That pram (or more specifically the carry tray underneath) is like a pack mule for all the junk that your kids need.

Can Google make an auto driving pram please? Something that can handle getting on/off public transport.
>Maybe one can run python on the network card rom too?
The network card ROM isn't microcontroller code, its just x86 code that runs on your main processor, called by the BIOS[1]. You could potentially hence have the OPs project run from the BootROM, if it would fit. It might be slightly tricky, as it runs as part of GRUB, which doesn't expect to find itself running from there.

Alternatively, the article mentions:
> Environments like Mirage OS (and other "just enough operating systems") could also add Python using the BITS code without too much difficulty, he said.

You could therefore probably add this code to iPXE [2] without too much trouble to get python on your BootROM, though I'm unsure how much of the C standard library you would need to borrow or reimplement. By the looks of it, iPXE doesn't have threads or local storage support, so you would be pretty limited in usability without a lot of work.

How to control someone else's arm with your brain
You're assuming that people prioritize anything above work. I work at a "come when you want" company and I always aim to have at least four hours of overlap with my team, even though we have a seven hour time difference.
Why Am I Still Single?
Mad props to you!

Your ex boss is an idiot, if he thought that putting you on the spot over 5 minutes was the right thing to do in that situation.

It's your boss that should review his priorities. Does he want clockwatchers or productive and happy employees?
Disable Javascript or install uMatrix to block frames/XHR entirely.
I can understand why investment type people like y-axes that don't start at zero - they're usually interested in tiny changes a long way from zero. But for the general public to watch? If you didn't already have an up to date feeling for the price of Twitter shares, then this whole report is meaningless without finding the -$9 and doing the calculation yourself. She even points out that it's now $40 but not what it was before. Are most viewers really that tuned into the market that they know the prices of things before they're in the news?

Turns out this is only something like 20% drop making it the same as February this year! Nothing spectacular at all. It endured a similar crash in October last year and took a few months to recover.

This will sound narcisstic, and calculating, but here goes; Make friends with people younger than you.

I never felt comfortable with people from my generation. I seemed to become friends with people older than myself. I didn't do it on a conscious level, but it happened. I would buy things like 8 person rafts, double kayaks, huge tents. Everything I planned for had another close person/girlfriend in mind.

They all passed away.

As to money, save that money you made in your 20-30's. For some reason(I think testosterone) most of the people I knew in life made the big money in their 20-30's. These were people without fancy degrees--four year degree at best.

Oh yea, you can be the best at a lot of things, and feel like you are on top of the world. You can feel like you can accomplish anything. All that can change overnight with mental illness. I had a slight nervous breakdown(not psychotic), and I went from being one of the better students in graduate school--to someone who couldn't drive to the school a week later. Life has been a struggle since. I tried therapy and it just didn't help. Prescription drugs did alleviate some of the missery, but I am now addicted to two drugs going on twenty years. There was no history of mental illness in my family. I didn't even feel stressed when I brokedown. (I did have a fear of death. I had typical worries of a twenty something year old.) I just blew a gasket. Yes, after dealing with psychiatrists who really didn't have any answers--that's what I feel what happened. I know it's rare. None of my classmates from high school/college experienced anything close to my symptomology. It did get better with time though. I usually don't tell anyone because I know it's rare. I do have a innate understanding of homelessness because of my condition though, and cringe when I hear, "You can do anything! It just takes proper planning!". Sometimes your brain just goes haywire.
> they have a nice advantage over Amazon for doing their own deliveries through their physical stores.

That is a nice point. Staples.com has been growing and is robust, while Staples Inc. stores have been shrinking (they're closing 225 stores by the end of 2015).

They don't break out brick & mortar from on-line in their earnings reports, so you have to infer.
Ultrasound helps because the speed of sound in air is much lower than the speed of radio waves. This makes it massively easier to do distance measurements.

Rather than put an ultrasonic speaker in the fob, I'd put a microphone. The car would send an ultrasonic signal, and the fob would send a radio response indicating it heard it. The car could then calculate how far away the fob is.
Thanks for the reply! Interesting use case, I did not think about that angle. Thanks for explaining it. I definitely see some use of this library now.
Left unchecked employers will use all kinds of BS to extract more hours out of their employees.

Being expected to 'work a small amount in the evenings and weekends' is ridiculous if you're not being compensated for that.
Coming soon: more ads. From the article: "Under a new agreement, marketers using Google’s DoubleClick advertising service can buy Twitter’s Promoted Tweets."

Twitter is in danger of pulling a Myspace. At Myspace, revenue went down, ad density was raised to compensate, usage went down, ad density was increased to compensate, then usage crashed. For a publicly held ad-based growth company, a down quarter is a disaster. The valuation as a growth company ends and the company starts to be valued based on its operations and earnings. Twitter currently has negative earnings.

Investors are now asking why Twitter costs so much money to run. Their revenue is $1.3 billion a year, yet they're losing money. They don't pay for content, their basic product isn't that complicated, and bulk compute and network costs are declining. Something is wrong there.
i think the problem is in generating revenue. According to their numbers, Twitter's user base is still trending upwards no?
Agile/scrum makes a valiant attempt with "user stories", but these frequently end up being precise specifications for the wing feathers of the actually desired magical flying unicorn pony.
So ... someone tricked a bot into triggering an uninformed crash of the stock? Pretty clever, if true.
fair enough--your numbers are well documented and are a better representation of the "average" big law firm. I was more pointing to the best of the best. I believe the top firms produce about 6MM profits per partner, though the profits aren't equally distributed among the partners
You read things you like reading.

There's more to be said about why you use Twitter instead of one of the other places you could read things, but the basic "value proposition" is actually simple.
Irony is a black box trading system listening to the firehose and picking up that nugget.
Yes, but the street cares about revenue because they care about profit. If you have high costs you can always just say you had a bad quarter but profit will come when costs come down.

Even if Twitter fired half its people and cut costs like crazy they'd still struggle to justify their current valuation. The street is angry at the reveune numbers since on this current trajectory there's not really a clear path for how the company can generate enough profit to justify its valuation... unless their revenue skyrockets, which is looking less and less likely evey quarter.
This is exactly my problem with systemd. It exposes new problems and issues while does not provide the same functionality that software it is replacing.
One strategy is to consider establishing a success metric as the first step to every project. If you can't design a measurement for success/failure, maybe you shouldn't be doing that project.
I don't see why not. You can take the result of some effort and say, OK, this is a model for the kind of result we'd like, but are not currently getting from our more open, idealistic systems. There would probably be many benefits to such, err...open ways of thinking.
Announcing the Auth0 Open Source Single-Sign-On Dashboard
I think the OP was asking a rhetorical question.
Are you serious? You are incapable of reading and understanding an 8 page document? Or learning general strategies of where to find summary information (hint: the beginning and end of every paper).

There's a lot of information loss when you try to fit an idea into a list of points.

And yes, your comment is quite ironic since it is incoherent, unorganized, lengthy, and ultimately, sounds like nothing more than a bunch of whining.
I don't disagree, but it just felt wrong, gross, and scummy to me to continue working on that project when I saw so clearly how they weren't giving a damn about people's privacy and taking advantage of the fact that, yes, like you said, FB could/would do nothing about it.
This is one dimension of the problem. I think from the technical point of view having a more efficient stack that cost you less and the change in the system is cheap (aka software engineering time) can make your product more profitable even though your competitors offer more features. This sort of angle is missed quite often in the startup scene, while older mature companies care about it a lot more. A good example would be Amazon.
Fortran predates the first examples of what we now think of as operating systems. After turning on the machine you fed in a deck of cards that comprised the Fortran compiler.
My partner and I (heterosexual relationship) have both independently decided to not have children. Personally, I was raised at first with an abysmal parent, and then by a slightly-better-but-still-not-good parent. Never had money, homeless, abusive, etc.

I don't want to have kids not because they left a bad taste in my mouth (I still love them: they were young, made a mistake, but still tried), but because I never got to experience all the things I wanted to as a child. So my life as a 20/30 something is dedicated to experiencing the world. Finding joy in others, in travels, in food, and in contribution.

That said, if children were ever to be an option, it must be adoption. It is so incredibly selfish to say that the (non-existent) child you might produce with a partner is more deserving of safety, freedom, and a fulfilling life, than an already living person. Granted, adoption is full of its own political and socioeconomic issues.
There are a few real devices which boot up into interpreters, like the Espruino, which runs Javascript (!):

"a government surveillance operation run by gullible volunteers, a Stasi for the Angry Birds generation”
I'm a recent college student and most of the people I know still in college use twitter. It seems our anecdotes are conflicting.
If there is one thing that rammed that home it was sitting next to an incubator watching O2 levels and heartbeat of an early born infant. Re-alignment of priorities would be a very mild way to describe the feeling.
While we will never return to the pre-social-media days, perhaps the infatuation had faded. The current generation entering their teens has never really known a time without it. There's no real novelty to it. The distinction between mindless time wasting and real usefulness may be more clear.
I've always wondered about how companies handle increasing complexity of their user base.

One route is to do what CloudFlare has done: create the "pro" UI where you have every setting imaginable across multiple namespaces.

Another is to simply make an API for everything and let your customers implement their own UI (usually integrating your product with the 15 other vendors they probably use).

I'm increasingly in favor of the second approach. A pro-user UI is great, but most of your customers who are complex enough to need a truly pro interface would be better served by an API. That was honestly the revolution that Amazon brought to the infrastructure space: they had an API you could use to provision... Well, anything.

So IMO the API is the new expert mode. There are just too many platforms out there (AWS, CloudFlare, Akamai, etc) that are often used in tandem that a vendor-provided interface will never be enough for the most advanced users.

Developer needed for lifesaving data
I'm an iOS engineer, and the company I work for recently started using Twitter's analytic tool Fabric for mobile crash debugging.

Until then I had also written Twitter off, but if they can monetize Fabric and leverage some of what they've learned about big data and how (not) to scale technical infrastructure, they may be able to position themselves as a technology solutions company that also has a limited character notification system.
Can someone explain hashicorps business model to me?

Love all the projects. Are they contracting out features to companies? Selling support contracts?

Very curious-- I think if people, especially individuals, can make a living from open source projects, that's great for everybody.

But do you have to be "famous" to do it?
that sounds heavy to me.

Generally using multiple channels and select is good when you have multiple threads sending. When there is a single sender, putting everything in one channel feels better to me.
Meh, I don't get it.

They're making money, they grew to 18% more active users (that sounds like a lot), what seems to be the problem?
> You could potentially hence have the OPs project run from the BootROM

Just pointing out as the OP that I'm not the author of the project. I just came across the article on r/python
To the best of my knowledge it comes from contracting/support and mostly their Vagrant Cloud (now Atlas) features that are business/enterprise only, which they charge money for. For example private hosting of Vagrant box images is a paid feature. The costs for that are per-user/per-month.
This is the ol' chunky (all of the bits for a pixel stored adjacently in memory) vs. planar (image broken up into separate "bitplanes") graphics debate. Planar was very common for early 2D hardware, as it was the natural extension of 1-bit monochrome display hardware, which would load a byte at a time into a shift register, shifting a bit out per pixel clock. Instead of needing to redesign the hardware around a larger shift register, you could just duplicate your existing shift register, shift them out in parallel, and combine the results with some simple logic.

It had a variety of benefits for simple 2D composition. For instance, it allowed for flexible bit depths in video modes. The Amiga (IIRC) allowed you to set up video modes with anywhere from 1 to 5 bits per pixel, while the SNES allowed 2, 4, and 8 bits per pixel formats; lower depth modes would simply load the unused shift registers with 0s, and everything would work the same. With chunky pixel hardware, this would have been unfeasible at the time, as the pixel format packing would change too much between bit depths. It was a handy feature to have, so that, say, text in an RPG could be placed on a monochrome layer that would not take up as much video memory, while the rest of the game could be rendered in full color.

The NES doesn't support flexible bit depths, but a similar principle allows a simple kind of "compression" when storing compressed graphics data in ROM: for a monochrome font, you wouldn't need to store the upper bitplane, and you'd just zero it out when loading the font. For chunky hardware, this process would be a bit more involved than that (no pun intended).

Of course, once you advance beyond simple 2D composition to software rasterization, the planar format becomes a liability. Rotating and scaling a bitmap, for instance, would involve making multiple unpredictable read-modify-write memory accesses per pixel, instead of just directly overwriting a pixel at a time.

Here are some links that discuss some of the other tradeoffs of the two formats, like how you can use planar formats to implement simple alpha blending effects for shadows and the like:

The Escher work used as illustration (re: Demons, et. al.) has a decidedly fractal look about it, which prompts the thought that the entanglement described in the article could be understood as a multidimensional fractal.

Kind of like the way polymerization of organic molecules occurs in specific ways and produces shaped structures accordingly, entangled particles build space-time shapes depending on patterns of entanglement, and perhaps not necessarily always the same pattern, leaving unevenness of space-time shape.

Just musing about the significance of the idea. It certainly has a lot of intuitive appeal.
Indeed. This is news if you're actively day trading Twitter shares. Otherwise it's business as usual. Now it's at 2014 prices. It's had bigger swings in both directions in the recent past.
